Migration of innumerable chronically retained acupuncture needles
Directory of Open Access Journals (Sweden)
Frances Lazarow, MD
2017-09-01
Full Text Available We present a case of a 50-year-old female with a 2-day history of back and abdominal pain who was discovered to have innumerable chronically retained acupuncture needles, which had migrated throughout her abdomen and pelvis. Although many of these needles were in precarious positions, including the epidural space, renal parenchyma, small bowel, and vasculature, there was no evidence for acute injury. We also briefly discuss evidence for the magnetic resonance imaging compatibility of acupuncture needles. Although a rare complication, given the high frequency of acupuncture therapy in the United States, physicians must be aware of the potential for retained and migrated needles.

Access to healthcare for disabled persons. How are blind people reached by HIV services?
Saulo, Bryson; Walakira, Eddy; Darj, Elisabeth
2012-03-01
Disabled people are overlooked and marginalised globally. There is a lack of information on blind people and HIV-related services and it is unclear how HIV-services target blind people in a sub-Saharan urban setting. To explore how blind people are reached by HIV-services in Kampala, Uganda. A purposeful sample of blind people and seeing healthcare workers were interviewed, and data on their opinions and experiences were collected. The data were analysed by qualitative content analysis, with a focus on manifest content. Three categories emerged from the study, reaching for HIV information and knowledge, lack of services, and experiences of discrimination. General knowledge on HIV prevention/transmission methods was good; however, there was scepticism about condom use. Blind people mainly relied on others for accessing HIV information, and a lack of special services for blind people to be able to test for HIV was expressed. The health service for blind people was considered inadequate, unequal and discriminatory, and harassment by healthcare staff was expressed, but not sexual abuse. Concerns about disclosure of personal medical information were revealed. Access to HIV services and other healthcare related services for blind people is limited and the objectives of the National Strategic Plan for HIV/AIDS 2007-2012 have not been achieved. There is a need for alternative methods for sensitisation and voluntary counselling and testing (VCT) for blind people. Copyright © 2011 Elsevier B.V. All rights reserved.

Innumerable treasures of the Zheleznaya Mountain
International Nuclear Information System (INIS)
Yakovlev, Nikolai E.
2001-01-01
Full text: In 2000 in Russia one of sharp problems, concerning a public, was the problem of importation of the foreign irradiated nuclear fuel (INF), unloaded from atomic power stations, on long-term storage (with its possible reprocessing in the future). The problem was, that, not looking on availability for Russia of major practical experience and most advanced technologies, economic, social and ecological validity of sharing of the Russian nuclear enterprises in the international market of a storage and reprocessing INF, the importation foreign INF required change of the current Russian legislation. It insufficiently legibly defined state policy in the field of the management with INF. With the initiative of change of the current legislation in 1999 the group of the deputies of State Duma (SD) has acted. However this initiative has not found broad support both among the deputies and the public. In this connection in 2000 the broad PR campaign to provide an explanation of necessity of the legislative solution of all problems of the management with INF, including possibility of importation for long-term storage foreign INF, was conducted. The basic purpose of this company was to bring to Russian public, authority bodies an economic feasibility, ecological safety of a storage and reprocessing INF at the Russian nuclear enterprises. Video film 'Innumerable Treasures of the Zheleznaya Mountain' tells about one of PR - shares of this company, namely, about trip of the group of the deputies on Mining Chemical Combine (MCC), city Zheleznogorsk (former Krasnoyarsk - 26). On this trip the deputies could personally on site acquaint with modern technologies of storage and reprocessing INF, ecological safety and economic efficiency. For many from the deputies this visit on MCC was the first visit on the Russian nuclear complex enterprise. Plants of MCC itself, the acting INF depository, laid up construction of the PT-2 plant on processing INF are widely presented in the

Paralysis following spinal cord injury (SCI), brainstem stroke, amyotrophic lateral sclerosis (ALS) and other disorders can disconnect the brain from the body, eliminating the ability to carry out volitional movements. A neural interface system (NIS)1–5 could restore mobility and independence for people with paralysis by translating neuronal activity directly into control signals for assistive devices. We have previously shown that people with longstanding tetraplegia can use an NIS to move and click a computer cursor and to control physical devices6–8. Able-bodied monkeys have used an NIS to control a robotic arm9, but it is unknown whether people with profound upper extremity paralysis or limb loss could use cortical neuronal ensemble signals to direct useful arm actions. Here, we demonstrate the ability of two people with long-standing tetraplegia to use NIS-based control of a robotic arm to perform three-dimensional reach and grasp movements. Participants controlled the arm over a broad space without explicit training, using signals decoded from a small, local population of motor cortex (MI) neurons recorded from a 96-channel microelectrode array. One of the study participants, implanted with the sensor five years earlier, also used a robotic arm to drink coffee from a bottle. While robotic reach and grasp actions were not as fast or accurate as those of an able-bodied person, our results demonstrate the feasibility for people with tetraplegia, years after CNS injury, to recreate useful multidimensional control of complex devices directly from a small sample of neural signals.

Centers for independent living (CILs) provide critical supports, services, and advocacy for assisting people with disabilities in living independently. As there is a rapidly increasing population of older people with disabilities, many CILs are now considering how to actively engage older adults in their organizations. This study utilized a survey of older people with disabilities to help identify social marketing techniques that community organizations like CILs can use to effectively reach older people with disabilities. Utilizing the components of the social marketing mix in designing outreach efforts, including a critical examination of product, place, price, participants, and partnering, CILs and other community agencies can better reach older adults with disabilities.

Auditory hallucinations (eg, hearing voices) are relatively common and underreported false sensory experiences that may produce distress and impairment. A large proportion of those who experience auditory hallucinations go unidentified and untreated. Traditional engagement methods oftentimes fall short in reaching the diverse population of people who experience auditory hallucinations. The objective of this proof-of-concept study was to examine the viability of leveraging Web-based social media as a method of engaging people who experience auditory hallucinations and to evaluate their attitudes toward using social media platforms as a resource for Web-based support and technology-based treatment. We used Facebook advertisements to recruit individuals who experience auditory hallucinations to complete an 18-item Web-based survey focused on issues related to auditory hallucinations and technology use in American adults. We systematically tested multiple elements of the advertisement and survey layout including image selection, survey pagination, question ordering, and advertising targeting strategy. Each element was evaluated sequentially and the most cost-effective strategy was implemented in the subsequent steps, eventually deriving an optimized approach. Three open-ended question responses were analyzed using conventional inductive content analysis. Coded responses were quantified into binary codes, and frequencies were then calculated. Recruitment netted N=264 total sample over a 6-week period. Ninety-seven participants fully completed all measures at a total cost of $8.14 per participant across testing phases. Systematic adjustments to advertisement design, survey layout, and targeting strategies improved data quality and cost efficiency. People were willing to provide information on what triggered their auditory hallucinations along with strategies they use to cope, as well as provide suggestions to others who experience auditory hallucinations.

This systematic review aimed to identify facilitators, barriers and strategies for engaging 'hard to reach' older people in research on health promotion; the oldest old (≥80 years), older people from black and minority ethnic groups (BME) and older people living in deprived areas. Eight databases were searched to identify eligible studies using quantitative, qualitative, and mixed research methods. Using elements of narrative synthesis, engagement strategies, and reported facilitators and barriers were identified, tabulated and analysed thematically for each of the three groups of older people. Twenty-three studies (3 with oldest-old, 16 with BME older people, 2 within deprived areas, 1 with both oldest-old and BME, 1 with both BME and deprived areas) were included. Methods included 10 quantitative studies (of which 1 was an RCT), 12 qualitative studies and one mixed-methods study. Facilitators for engaging the oldest old included gaining family support and having flexible sessions. Facilitators for BME groups included building trust through known professionals/community leaders, targeting personal interests, and addressing ethnic and cultural characteristics. Among older people in deprived areas, facilitators for engagement included encouragement by peers and providing refreshments. Across all groups, barriers for engagement were deteriorating health, having other priorities and lack of transport/inaccessibility. Feeling too tired and lacking support from family members were additional barriers for the oldest old. Similarly, feeling too tired and too old to participate in research on health promotion were reported by BME groups. Barriers for BME groups included lack of motivation and self-confidence, and cultural and language differences. Barriers identified in deprived areas included use of written recruitment materials. Strategies to successfully engage with the oldest old included home visits and professionals securing consent if needed. Strategies to engage

To explore ideas of the target population about a community-based intervention to stimulate physical activity in hard-to-reach physically disabled people. Semi-structured interviews were performed with 21 physically disabled people, and analyzed using thematic analyses. Findings were interpreted using the integrated Physical Activity for People with a Disability and Intervention Mapping model. The intervention should aim to stimulate intrinsic motivation and raise awareness for the health effects of physical activity. It should provide diverse activities, increase visibility of these activities, and improve image of physical activity for physically disabled people. Participants suggested to provide individual coaching sessions, increase marketing, present role models, and assign buddies. Potential users should be approached personally through intermediate organizations, or via social media and word of mouth promotion. Participants suggested that users, government, sponsors, and health insurers should finance the intervention. Self-responsibility for being physically active was strongly emphasized by participants. An intervention to stimulate physical activity in hard-to-reach physically disabled people should be individualized, include personal support, and should include marketing to improve image of physical activity of physically disabled people. The intervention that fulfills these requirements should be developed and tested for effects in future research. Implications for rehabilitation An intervention to stimulate physical activity in physically disabled people should aim to raise awareness for the health effects of physical activity, stimulate intrinsic motivation, offer diverse activities, increase the visibility of the possible activities, and improve the image of physical activity for physically disabled people. An intervention should include both individual- and environmental-level intervention methods. Physically disabled people most emphasized

Numbers for the Innumerate: Everyday Arithmetic and Atlantic Capitalism.
Rosenthal, Caitlin
In nineteenth-century America and the Atlantic world, the "rule of three" was usually regarded as the endpoint of a basic mathematics education. This essay considers the importance of the rule as a technology that enabled broader access to the calculations necessary to participate in the increasingly global market economy. Used by workmen, women, and even the enslaved, the rule and related tools translated basic literacy into practical numeracy. By doing so, it offered a diverse range of people the ability to negotiate more effectively. At the same time, however, the rule's spread helped to legitimate particular types of exchange and commensuration, and with them the emerging capitalist economy.

Embodied in the child survival revolution are ideological, methodological, and organizational innovations aimed at radical change in the condition of the world's children as rapidly as possible. In countries such as Sri Lanka, child survival and health for all by the year 2000 often seem to be impossible goals, given the tumultuous socioeconomic and political conditions. In Sri Lanka, the quality of life has been eroded, not enhanced, by the importation of Western technology and managerial capitalism and the destruction of indigenous processes. The chaos and violence that have been brought into the country have made it difficult to reach the poor children, women, and refugees in rural areas with primary health care interventions. Sri Lanka's unreachable--the decision making elites--have blocked access to the unreached--the urban and rural poor. If governments are to reach the unreached, they must remove the obstacles to a people-centered, community development process. It is the people themselves, and the institutions of their creation, that can reach the children amidst them in greatest need. To achieve this task, local communities must be provided with basic human rights, the power to make decisions that affect their lives, necessary resources, and appropriate technologies. Nongovernmental organizations can play a crucial role as bridges between the unreached and the unreachable by promoting community empowerment, aiding in the formation of networks of community organizations, and establishing linkages with government programs. If the ruling elites in developing countries can be persuaded to accommodate the needs and aspirations of those who, to date, have been excluded from the development process, the child survival revolution can be a nonviolent one.

Full Text Available We studied the behavioral and emotional dynamics displayed by two people trying to resolve a conflict. 59 groups of two people were asked to talk for 20 minutes to try to reach a consensus about a topic on which they disagreed. The topics were abortion, affirmative action, death penalty, and euthanasia. Behavior data were determined from audio recordings where each second of the conversation was assessed as proself, neutral, or prosocial. We determined the probability density function of the durations of time spent in each behavioral state. These durations were well fit by a stretched exponential distribution, [Formula: see text] with an exponent, [Formula: see text], of approximately 0.3. This indicates that the switching between behavioral states is not a random Markov process, but one where the probability to switch behavioral states decreases with the time already spent in that behavioral state. The degree of this "memory" was stronger in those groups who did not reach a consensus and where the conflict grew more destructive than in those that did. Emotion data were measured by having each person listen to the audio recording and moving a computer mouse to recall their negative or positive emotional valence at each moment in the conversation. We used the Hurst rescaled range analysis and power spectrum to determine the correlations in the fluctuations of the emotional valence. The emotional valence was well described by a random walk whose increments were uncorrelated. Thus, the behavior data demonstrated a "memory" of the duration already spent in a behavioral state while the emotion data fluctuated as a random walk whose steps did not have a "memory" of previous steps. This work demonstrates that statistical analysis, more commonly used to analyze physical phenomena, can also shed interesting light on the dynamics of processes in social psychology and conflict management.

Physically disabled people are less physically active compared with healthy people. Existing physical activity (PA) interventions are limited in reach, since they are primarily rehabilitation or school based. The current study aims to develop a community-based intervention for stimulating PA in hard-to-reach physically disabled people. To systematically develop a PA-stimulating intervention, intervention mapping (six steps) was applied. PA level and health-related quality of life of patients after rehabilitation was determined using questionnaires (step 1). Qualitative research was performed to study professionals' and physically disabled people's ideas about intervention objectives, determinants and design (steps 2 and 3). Since experts expressed no need for a new intervention, the existing intervention 'Activity coach' was adapted to the specific target population. The adapted intervention 'Activity coach+' composes a network of intermediate organisations that refers participants to an activity coach, who coaches participants during 1 year. After a preintervention physical assessment by a physiotherapist, participants will be individually guided to existing organised or non-organised activities. An activity tracker will be used to monitor and stimulate PA in daily life (step 4). To support adoption and implementation, meetings between involved parties are organised (step 5). 'Activity coach+' is implemented in community in March 2017, and will be evaluated using a mixed-method analysis. Quantitative evaluation of intervention effects on PA, health and social participation takes place after 0, 2, 4, 6 and 12 months. The implementation process and experiences with the intervention will be determined using qualitative research (step 6). Insights from this study will be used for dissemination and further development of the intervention. The Medical Ethical Committee of the University Medical Center Groningen confirmed that formal ethical approval was not required

Feedforward control strategies of subjects with transradial amputation in planar reaching.
Metzger, Anthony J; Dromerick, Alexander W; Schabowsky, Christopher N; Holley, Rahsaan J; Monroe, Brian; Lum, Peter S
2010-01-01
The rate of upper-limb amputations is increasing, and the rejection rate of prosthetic devices remains high. People with upper-limb amputation do not fully incorporate prosthetic devices into their activities of daily living. By understanding the reaching behaviors of prosthesis users, researchers can alter prosthetic devices and develop training protocols to improve the acceptance of prosthetic limbs. By observing the reaching characteristics of the nondisabled arms of people with amputation, we can begin to understand how the brain alters its motor commands after amputation. We asked subjects to perform rapid reaching movements to two targets with and without visual feedback. Subjects performed the tasks with both their prosthetic and nondisabled arms. We calculated endpoint error, trajectory error, and variability and compared them with those of nondisabled control subjects. We found no significant abnormalities in the prosthetic limb. However, we found an abnormal leftward trajectory error (in right arms) in the nondisabled arm of prosthetic users in the vision condition. In the no-vision condition, the nondisabled arm displayed abnormal leftward endpoint errors and abnormally higher endpoint variability. In the vision condition, peak velocity was lower and movement duration was longer in both arms of subjects with amputation. These abnormalities may reflect the cortical reorganization associated with limb loss.

Everyone has a role to play in realizing the goals of the International Conference on Population and Development (ICPD) program of action. The concerns of young people presented at the Youth Forum will hopefully be kept at the forefront of Cairo+5 deliberations. Innumerable women around the world in every country struggle daily to care for and education their children, to gain greater control over their lives, and to contribute to the progress being made in their communities and countries. The nongovernmental organization (NGO) and youth fora of the Cairo+5 proceedings demonstrate that the discussions about global challenges and their solutions are no longer being held and decided upon solely by government officials and policy-makers behind closed doors. Rather, NGOs have finally taken their proper place in the debate, to help ordinary citizens be heard on the critical issues which affect their lives. Efforts must also continue to be made to reach out to young people, as well as fathers, sons, and husbands.

Guatemala's family planning (FP) programs are innovative but contraceptive use is only 23%. Total fertility is 5.3 children/woman, and the 9.5 million population will double in 23 years. The problem is poverty and illiteracy among rural residents removed from health services. 80% live in poverty and 80% are illiterate. Government effort is devoted to combating diseases such as diarrhea so there are few funds for implementing a comprehensive population policy. There is support within the national government but FP lacks priority status. APROFAM's goals are to use innovative marketing methods to inform the rural population who lack access to and knowledge about FP. Service delivery is constrained by the difficulty in reaching remote areas where 4 out of 10 indigenous Guatemalans live. Infant mortality can reach as high as 200/1000 live births. Population growth has slowed, and APROFAM plans to reach 16,000 more in the future. Promotions are conducted in several languages and aired on radio, television, and in the print media. It has been found that market research is the most effective strategy in reaching indigenous families. APROFAM has also been effective in upgrading service facilities through training, client surveys, and setting improved clinic standards. Breastfeeding, training, and voluntary sterilization programs contribute to the primary care effort. The example is given of Paulina Lebron from a very poor area who has learned how to space her children and thus improve the standard of living for her family. Eventually, she convinced herself and her family that sterilization was necessary, and now the couple enjoy the bliss of newlyweds without fear of pregnancy.

Reach Out Central (ROC) is a serious game drawing on the principles of cognitive behaviour theory that has been designed to improve the mental health and wellbeing of young people, particularly men. ROC was developed over a 3-year period from 2003 to 2006, in consultation with young people aged 16-25 years who use the Reach Out mental health website http://www.reachout.com). ROC was launched online in September 2007. A traditional and viral awareness campaign was designed to engage young men, particularly "gamers". In the first month after launch, ROC had 76 045 unique website visits, with 10 542 new members (52% male) joining Reach Out. An independent online evaluation involving 266 young people aged 18-25 years was conducted between August 2007 and February 2008 to examine psychological wellbeing, stigma and help seeking in ROC players. Overall results indicated that ROC was successful in attracting, engaging and educating young people. Young women reported reduced psychological distress and improved life satisfaction, problem solving and help seeking; however, no significant changes were observed for young men. Although ROC was successful in attracting young men, demonstrating that the concept resonates with them, the service failed to keep them engaged. Further research is needed to explore how (or what changes need to be made) to sustain young men's engagement in the game.

We aimed to establish the support needs of people with heart failure and their caregivers and develop an intervention to improve their health-related quality of life. We used intervention mapping to guide the development of our intervention. We identified "targets for change" by synthesising research evidence and international guidelines and consulting with patients, caregivers and health service providers. We then used behaviour change theory, expert opinion and a taxonomy of behaviour change techniques, to identify barriers to and facilitators of change and to match intervention strategies to each target. A patient and public involvement group helped to identify patient and caregiver needs, refine the intervention objectives and strategies and deliver training to the intervention facilitators. A feasibility study (ISRCTN25032672) involving 23 patients, 12 caregivers and seven trained facilitators at four sites assessed the feasibility and acceptability of the intervention and quality of delivery and generated ideas to help refine the intervention. The Rehabilitation Enablement in Chronic Heart Failure (REACH-HF) intervention is a comprehensive self-care support programme comprising the "Heart Failure Manual", a choice of two exercise programmes for patients, a "Family and Friends Resource" for caregivers, a "Progress Tracker" tool and a facilitator training course. The main targets for change are engaging in exercise training, monitoring for symptom deterioration, managing stress and anxiety, managing medications and understanding heart failure. Secondary targets include managing low mood and smoking cessation. The intervention is facilitated by trained healthcare professionals with specialist cardiac experience over 12 weeks, via home and telephone contacts. The feasibility study found high levels of satisfaction and engagement with the intervention from facilitators, patients and caregivers.

Full Text Available Cervical spinal cord injury (SCI paralyzes muscles of the hand and arm, making it difficult to perform activities of daily living. Restoring the ability to reach can dramatically improve quality of life for people with cervical SCI. Any reaching system requires a user interface to decode parameters of an intended reach, such as trajectory and target. A challenge in developing such decoders is that often few physiological signals related to the intended reach remain under voluntary control, especially in patients with high cervical injuries. Furthermore, the decoding problem changes when the user is controlling the motion of their limb, as opposed to an external device. The purpose of this study was to investigate the benefits of combining disparate signal sources to control reach in people with a range of impairments, and to consider the effect of two feedback approaches. Subjects with cervical SCI performed robot-assisted reaching, controlling trajectories with either shoulder electromyograms (EMGs or EMGs combined with gaze. We then evaluated how reaching performance was influenced by task-related sensory feedback, testing the EMG-only decoder in two conditions. The first involved moving the arm with the robot, providing congruent sensory feedback through their remaining sense of proprioception. In the second, the subjects moved the robot without the arm attached, as in applications that control external devices. We found that the multimodal decoding algorithm worked well for all subjects, enabling them to perform straight, accurate reaches. The inclusion of gaze information, used to estimate target location, was especially important for the most impaired subjects. In the absence of gaze information, congruent sensory feedback improved performance. These results highlight the importance of proprioceptive feedback, and suggest that multi-modal decoders are likely to be most beneficial for highly impaired subjects and in tasks where such

Audience reach of science on television in 10 European countries: An analysis of people-meter data.
Lehmkuhl, Markus; Boyadjieva, Pepka; Cunningham, Yvonne; Karamanidou, Christina; Mörä, Tuomo
2016-02-01
Beginning with a differentiation of science programmes into five different editorial concepts, this article explores the audience reach of science on television in 10 European countries with a special emphasis on young audiences aged between 14 and 29 years. In relation to the share of this age group in the entire population, science programmes in all countries reach a considerably smaller proportion of younger viewers. Specific preferences for science content on television do not seem to be relevant in explaining aggregated viewing behaviours especially of young audiences. Unlike all other segments, the young science viewer segment is almost intangible as an aggregated group, as a definable segment of a mass audience that can be targeted by science programme makers. © The Author(s) 2014.

The creation of the world's largest sandstone cavern, not a small feat! At the bottom, cave-in preventing steel mesh can be seen clinging to the top of the tunnel. The digging of UX-15, the cavern that will house ATLAS, reached the upper ceiling of LEP on October 10th. The breakthrough which took place nearly 100 metres underground occurred precisely on schedule and exactly as planned. But much caution was taken beforehand to make the LEP breakthrough clean and safe. To prevent the possibility of cave-ins in the side tunnels that will eventually be attached to the completed UX-15 cavern, reinforcing steel mesh was fixed into the walls with bolts. Obviously no people were allowed in the LEP tunnels below UX-15 as the breakthrough occurred. The area was completely evacuated and fences were put into place to keep all personnel out. However, while personnel were being kept out of the tunnels below, this has been anything but the case for the work taking place up above. With the creation of the world's largest...

With large numbers of young people experiencing mental health difficulties but not seeking help, there is a need to develop not only innovative but also well-promoted strategies that are appealing to this population and reduce barriers to help seeking. Reach Out! (http://www.reachout.com.au) is presented as a case study, demonstrating an internet-based initiative that sucessfully incorporates technology and social branding to provide a service that promotes the mental health and wellbeing of young people in Australia aged 16 to 25. With over seven million visits since its launch in 1998 and one in three young Australians aware of the website, Reach Out! is a trusted service that young people in Australia use when going through a tough time. Online user profiling suggests that after visiting Reach Out!, 38% of young people contact a mental health professional. The implications of these results will be discussed. Reach Out! can serve as a model for the social sector to utilize technology and social branding to enhance existing community-based services and promote the mental health and wellbeing of young people.

Media perspective - new opportunities for reaching audiences
Haswell, Katy
2007-08-01
The world of media is experiencing a period of extreme and rapid change with the rise of internet television and the download generation. Many young people no longer watch standard TV. Instead, they go on-line, talking to friends and downloading pictures, videos, music clips to put on their own websites and watch/ listen to on their laptops and mobile phones. Gone are the days when TV controllers determined what you watched and when you watched it. Now the buzzword is IPTV, Internet Protocol Television, with companies such as JOOST offering hundreds of channels on a wide range of subjects, all of which you can choose to watch when and where you wish, on your high-def widescreen with stereo surround sound at home or on your mobile phone on the train. This media revolution is changing the way organisations get their message out. And it is encouraging companies such as advertising agencies to be creative about new ways of accessing audiences. The good news is that we have fresh opportunities to reach young people through internet-based media and material downloaded through tools such as games machines, as well as through the traditional media. And it is important for Europlanet to make the most of these new and exciting developments.

Full Text Available This article acknowledges the need for Church Planting Movements among the unreached peoples of India. Of particular concern to this study is the application of Church Planting Movement strategy to forward caste Hindus of India. It is shown that evangelizing households (family or �oikos� evangelism is a New Testament strategy and the most appropriate strategy for reaching forward caste Hindus. It is concluded that Christian disciples remaining within Hindu culture and familial systems hold the potential for the most indigenous approach to evangelizing forward caste Hindus.

Despite a dominant view within Western biomedicine that children and medicines should be kept apart, a growing literature suggests that children and adolescents often take active roles in health-seeking. Here, we consider young people's health-seeking practices in Ghana: a country with a rapidly-changing therapeutic landscape, characterised by the recent introduction of a National Health Insurance Scheme, mass advertising of medicines, and increased use of mobile phones. Qualitative and quantitative data are presented from eight field-sites in urban and rural Ghana, including 131 individual interviews, focus groups, plus a questionnaire survey of 1005 8-to-18-year-olds. The data show that many young people in Ghana play a major role in seeking healthcare for themselves and others. Young people's ability to secure effective healthcare is often constrained by their limited access to social, economic and cultural resources and information; however, many interviewees actively generated, developed and consolidated such resources in their quest for healthcare. Health insurance and the growth of telecommunications and advertising present new opportunities and challenges for young people's health-seeking practices. We argue that policy should take young people's medical realities as a starting point for interventions to facilitate safe and effective health-seeking. Copyright © 2011 Elsevier Ltd.

Delays in using chromatic and luminance information to correct rapid reaches.
Kane, Adam; Wade, Alex; Ma-Wyatt, Anna
2011-09-07
People can use feedback to make online corrections to movements but only if there is sufficient time to integrate the new information and make the correction. A key variable in this process is therefore the speed at which the new information about the target location is coded. Conduction velocities for chromatic signals are lower than for achromatic signals so it may take longer to correct reaches to chromatic stimuli. In addition to this delay, the sensorimotor system may prefer achromatic information over the chromatic information as delayed information may be less valuable when movements are made under time pressure. A down-weighting of chromatic information may result in additional latencies for chromatically directed reaches. In our study, participants made online corrections to reaches to achromatic, (L-M)-cone, and S-cone stimuli. Our chromatic stimuli were carefully adjusted to minimize stimulation of achromatic pathways, and we equated stimuli both in terms of detection thresholds and also by their estimated neural responses. Similar stimuli were used throughout the subjective adjustments and final reaching experiment. Using this paradigm, we found that responses to achromatic stimuli were only slightly faster than responses to (L-M)-cone and S-cone stimuli. We conclude that the sensorimotor system treats chromatic and achromatic information similarly and that the delayed chromatic responses primarily reflect early conduction delays.

Reaching High-Need Youth Populations With Evidence-Based Sexual Health Education in California.
Campa, Mary I; Leff, Sarah Z; Tufts, Margaret
2018-02-01
To explore the programmatic reach and experience of high-need adolescents who received sexual health education in 3 distinct implementation settings (targeted-prevention settings, traditional schools, and alternative schools) through a statewide sexual health education program. Data are from youth surveys collected between September 2013 and December 2014 in the California Personal Responsibility Education Program. A sample of high-need participants (n = 747) provided data to examine the impact of implementation setting on reach and program experience. Implementation in targeted-prevention settings was equal to or more effective at providing a positive program experience for high-need participants. More than 5 times as many high-need participants were served in targeted-prevention settings compared with traditional schools. Reaching the same number of high-need participants served in targeted-prevention settings over 15 months would take nearly 7 years of programming in traditional schools. To maximize the reach and experience of high-need youth populations receiving sexual health education, state and local agencies should consider the importance of implementation setting. Targeted resources and efforts should be directed toward high-need young people by expanding beyond traditional school settings.

Agents That Negotiate Proficiently with People
Kraus, Sarit
Negotiation is a process by which interested parties confer with the aim of reaching agreements. The dissemination of technologies such as the Internet has created opportunities for computer agents to negotiate with people, despite being distributed geographically and in time. The inclusion of people presents novel problems for the design of autonomous agent negotiation strategies. People do not adhere to the optimal, monolithic strategies that can be derived analytically, as is the case in settings comprising computer agents alone. Their negotiation behavior is affected by a multitude of social and psychological factors, such as social attributes that influence negotiation deals (e.g., social welfare, inequity aversion) and traits of individual negotiators (e.g., altruism, trustworthiness, helpfulness). Furthermore, culture plays an important role in their decision making and people of varying cultures differ in the way they make offers and fulfill their commitments in negotiation.

Bimanual reach to grasp movements after cervical spinal cord injury.
Directory of Open Access Journals (Sweden)
Laura Britten
Full Text Available Injury to the cervical spinal cord results in bilateral deficits in arm/hand function reducing functional independence and quality of life. To date little research has been undertaken to investigate control strategies of arm/hand movements following cervical spinal cord injury (cSCI. This study aimed to investigate unimanual and bimanual coordination in patients with acute cSCI using 3D kinematic analysis as they performed naturalistic reach to grasp actions with one hand, or with both hands together (symmetrical task, and compare this to the movement patterns of uninjured younger and older adults. Eighteen adults with a cSCI (mean 61.61 years with lesions at C4-C8, with an American Spinal Injury Association (ASIA grade B to D and 16 uninjured younger adults (mean 23.68 years and sixteen uninjured older adults (mean 70.92 years were recruited. Participants with a cSCI produced reach-to-grasp actions which took longer, were slower, and had longer deceleration phases than uninjured participants. These differences were exacerbated during bimanual reach-to-grasp tasks. Maximal grasp aperture was no different between groups, but reached earlier by people with cSCI. Participants with a cSCI were less synchronous than younger and older adults but all groups used the deceleration phase for error correction to end the movement in a synchronous fashion. Overall, this study suggests that after cSCI a level of bimanual coordination is retained. While there seems to be a greater reliance on feedback to produce both the reach to grasp, we observed minimal disruption of the more impaired limb on the less impaired limb. This suggests that bimanual movements should be integrated into therapy.

The posterior parietal cortex (PPC) has traditionally been considered important for awareness, spatial perception, and attention. However, recent findings provide evidence that the PPC also encodes information important for making decisions. These findings have initiated a running argument of whether the PPC is critically involved in decision making. To examine this issue, we reversibly inactivated the parietal reach region (PRR), the area of the PPC that is specialized for reaching movements, while two monkeys performed a memory-guided reaching or saccade task. The task included choices between two equally rewarded targets presented simultaneously in opposite visual fields. Free-choice trials were interleaved with instructed trials, in which a single cue presented in the peripheral visual field defined the reach and saccade target unequivocally. We found that PRR inactivation led to a strong reduction of contralesional choices, but only for reaches. On the other hand, saccade choices were not affected by PRR inactivation. Importantly, reaching and saccade movements to single instructed targets remained largely intact. These results cannot be explained as an effector-nonspecific deficit in spatial attention or awareness, since the temporary "lesion" had an impact only on reach choices. Hence, the PPR is a part of a network for reach decisions and not just reach planning. There has been an ongoing debate on whether the posterior parietal cortex (PPC) represents only spatial awareness, perception, and attention or whether it is also involved in decision making for actions. In this study we explore whether the parietal reach region (PRR), the region of the PPC that is specialized for reaches, is involved in the decision process. We inactivated the PRR while two monkeys performed reach and saccade choices between two targets presented simultaneously in both hemifields. We found that inactivation affected only the reach choices, while leaving saccade choices intact

Reaching remote areas in Latin America.
Jaimes, R
1994-01-01
Poor communities in remote and inaccessible areas tend to not only be cut off from family planning education and services, but they are also deprived of basic primary health care services. Efforts to bring family planning to such communities and populations should therefore be linked with other services. The author presents three examples of programs to bring effective family planning services to remote communities in Central and South America. Outside of the municipal center in the Tuxtlas region of Mexico, education and health levels are low and people live according to ancient customs. Ten years ago with the help of MEXFAM, the IPPF affiliate in Mexico, two social promoters established themselves in the town of Catemaco to develop a community program of family planning and health care offering education and prevention to improve the quality of people's lives. Through their health brigades taking health services to towns without an established health center, the program has influenced an estimated 100,000 people in 50 villages and towns. The program also has a clinic. In Guatemala, the Family Welfare Association (APROFAM) gave bicycles to 240 volunteer health care workers to facilitate their outreach work in rural areas. APROFAM since 1988 has operated an integrated program to treat intestinal parasites and promote family planning in San Lucas de Toliman, an Indian town close to Lake Atitlan. Providing health care to more than 10,000 people, the volunteer staff has covered the entire department of Solola, reaching each family in the area. Field educators travel on motorcycles through the rural areas of Guatemala coordinating with the health volunteers the distribution of contraceptives at the community level. The Integrated Project's Clinic was founded in 1992 and currently carries out pregnancy and Pap tests, as well as general lab tests. Finally, Puna is an island in the middle of the Gulf of Guayaquil, Ecuador. Women on the island typically have 10

The aim of the study was to evaluate the effectiveness of Dry Blood Spot testing (DBST) for hepatitis C within a geographical area. This is a prospective cohort study of all individuals living in Tayside who had received a hepatitis C virus (HCV) DBST between 2009 and 2011. During the study, 1123 DBSTs were carried out. 946 individuals had one test. 295 (31.2%) of these individuals were HCV antibody positive on their first test. Overall, 94.3% (902/956) individuals returned for the results of their test. During the course of the study 177 individuals were retested and 29 new cases of hepatitis C were detected. 249 individuals attended for further follow-up, and 164 (65.5%) were PCR positive. All 164 PCR-positive individuals were offered referral into specialist HCV services for further assessment. Data showed 62.5% were genotype 3, 65.1% had a low viral load (<600 000 iu/ml) and 77.5% had a Fibroscan score below 7 KPa. To date, 40 have commenced treatment and a further 16 are currently in the assessment period. Overall, we have retained in services or treated 63.6% (105/164) of patients who were initially referred and with effective support mechanisms in place we have achieved sustained viral response rates of 90%. The study has shown that DBST is a complementary technique to conventional venepuncture for the diagnosis of HCV. The majority of patients have low viral loads and low fibrosis scores, so that while this group of patients may be difficult to reach and may be challenging to maintain in therapy, they are easier to cure.

Somatosensory impairments are common in multiple sclerosis. However, little data are available to characterize the nature and frequency of these problems in people with multiple sclerosis. To investigate the frequency of somatosensory impairments and identify any association with balance limitations in people with multiple sclerosis. The design was a prospective cross-sectional study, involving 82 people with multiple sclerosis and 30 healthy controls. Tactile and proprioceptive sensory acuity were measured using the Rivermead Assessment of Somatosensory Performance. Vibration duration was assessed using a tuning fork. Duration for the Timed Up and Go Test and reaching distance of the Functional Reach Test were measured to assess balance limitations. The normative range of sensory modalities was defined using cut-off points in the healthy participants. The multivariate linear regression was used to identify the significant predictors of balance in people with multiple sclerosis. Proprioceptive impairments (66.7%) were more common than tactile (60.8%) and vibration impairments (44.9%). Somatosensory impairments were more frequent in the lower limb (78.2%) than the upper limb (64.1%). All sensory modalities were significantly associated with the Timed Up and Go and Functional Reach tests (plimitation. Copyright © 2017 Elsevier B.V. All rights reserved.

How Physics World reaches out in a digital age
Durrani, Matin
Physics World is an award-winning international magazine that exists in print and digital formats. Exploiting the opportunities available with digital publishing and apps, our output has expanded hugely in recent years to include technology-linked focus issues, regional special reports on the likes of China, India, Mexico and Brazil, plus audio, video and interactive material too. This growth in content - and new media for presenting physics - reflects wider changes in communication. People increasingly want to access content in a manner and time of their choosing, seeking out information presented in a way that suits them and their needs. That can be challenging for physics communicators because it means tailoring your message to different audiences and the medium they are using. But it's exciting too as you can reach out to many more people into physics - and in many different ways - than was possible in the past. This talk outlines some principles of good communication, including telling a good story, bearing the reader, viewer or listener in mind, using appropriate media, keeping up with social media, and exploiting the power of video. But with new forms of communication constantly emerging, it's worth remembering there is no one ``right answer''.

This article highlights findings from an evaluation that explored the impact of mobile versus clinic-based testing, rapid versus central-lab based testing, incentives for testing, and the use of a computer counseling program to guide counseling and automate evaluation in a mobile program reaching people of color at risk for HIV. The program’s results show that an increased focus on mobile outreach using rapid testing, incentives and health information technology tools may improve program acceptability, quality, productivity and timeliness of reports. This article describes program design decisions based on continuous quality assessment efforts. It also examines the impact of the Computer Assessment and Risk Reduction Education computer tool on HIV testing rates, staff perception of counseling quality, program productivity, and on the timeliness of evaluation reports. The article concludes with a discussion of implications for programmatic responses to the Centers for Disease Control and Prevention’s HIV testing recommendations. PMID:21689041

LEP Dismantling Reaches Half-Way Stage
2001-01-01
LEP's last superconducting module leaves its home port... Just seven months into the operation, LEP dismantling is forging ahead. Two of the eight arcs which form the tunnel have already been emptied and the last of the accelerator's radiofrequency (RF) cavities has just been raised to the surface. The 160 people working on LEP dismantling have reason to feel pleased with their progress. All of the accelerator's 72 superconducting RF modules have already been brought to the surface, with the last one being extracted on 2nd May. This represents an important step in the dismantling process, as head of the project, John Poole, explains. 'This was the most delicate part of the project, because the modules are very big and they could only come out at one place', he says. The shaft at point 1.8 through which the RF cavity modules pass is 18 metres in diameter, while each module is 11.5 metres long. Some modules had to travel more than 10 kilometres to reach the shaft. ... is lifted up the PM 1.8 shaft, after a m...

The meaning of the body schema in reaching maturity during late adolescence
Directory of Open Access Journals (Sweden)
Mirucka Beata
2016-04-01
Full Text Available The objective of the research presented in this paper was to investigate whether an association existed between the activation of the body schema and reaching adulthood among people in late adolescence. Three activities that are known to enjoy popularity among young people were analysed, namely: dancing, playing computer games that require motor involvement (e.g. Kinect, and playing computer games of an educational and entertaining character. It was assumed that the chosen forms of activity correspond to three levels of activation of the body schema. The following research methods have been applied to this study: the Rosenberg Self-Esteem Scale (SES, the Defence Style Questionnaire (DSQ, and the Bodily Self Representation Questionnaire. The study has proven that the activation of body schema through dance is significantly related to high self-esteem and the use of mainly mature and neurotic defence mechanisms in threat situations.

On geo-basis of river regulation——A case study for the middle reaches of the Yangtze River
Institute of Scientific and Technical Information of China (English)
2008-01-01
From the point of view that people have to obey the river’s geo-attributes in the river regulation, the definition and the meaning of the geo-attributes of a river are discussed. The geo-basis of the river regulation of the middle reaches of the Yangtze River is expounded in five aspects, including the structural geomorphology environment of flood storage and discharge, the distribution characteristics of subsidence and the sedimentation areas of Dongting Basin, the history evolution of Jianghan Basin, the function of Jianghan Basin and Dongting Basin as the flood water detention areas of Jingjiang River reach in ancient time, and the geological characteristic of Jingjiang River reach. Based on the geo-attributes of the middle reaches of the Yangtze River, some ideas about the middle reach regulation of the Yangtze River are put forward: to process the interchange between the lakes and diked marsh areas in Dongting Basin, to canal the new river route as the flood diversion channel of Jingjiang River reach with the paleo river, to recover the function of Jianghan Basin as flood detention area of the middle reaches. And we should take into consideration the geo-environment of the whole Yangtze River in the river regulation of middle reaches.

Reaching the hip-hop generation: Final (symposium proceedings) report
Energy Technology Data Exchange (ETDEWEB)
1993-05-01
The goal of this final (closing) report is to capture the flavor of the symposium held March 1 and 2, 1993 in New York City convened by Motivational Educational Entertainment, Inc. (MEE), a black-owned communications research, consulting, and video production company based in Philadelphia, Pennsylvania. The mission of MEE is to understand, reach, and positively affect inner-city youth. Traditional communication approaches from mainstream sources to at-risk youth often don`t account for the unique way youth communicate among themselves and how they relate to the media. This understanding, however, is crucial. To understand youth communication, the people who create and send both entertaining and educational messages to urban youth must be brought into the dialogue. The meeting in New York was intended to provide an important opportunity for senders to meet and evaluate the appropriateness and effectiveness of their messages. In addition, the MEE symposium provided a forum for the continuing public debate about what needs to be done to reach today`s urban teens. Included in this document is a description of symposium goals/objectives, symposium activities, the reaction to and analysis of the symposium, recommendations for future MEE courses of action, and an appendix containing copies of press articles.

Do transgender people get old?
Directory of Open Access Journals (Sweden)
Pedro Paulo Sammarco Antunes
2012-06-01
Full Text Available This study is aimed to understand transgender aging context in Brazil. Normal and abnormal were especially created by biological sciences. For being considered deviants, transgender people are not seen as human beings. They end up living in violent environments. Their life expectancy is low. Many of them do not believe to reach old age. They face a lot of prejudice and death threat. Those who get to what we call old age are considered survivals. This investigation was able to show satisfactorily their demands and needs. To be considered visible, they have to count on public policies to give them existence since their childhood. That way, we believe they will reach what we call old age with respect and dignity, already assured by theUniversal Human Rights.

Bibliotherapy in a Library Setting: Reaching out to Vulnerable Youth
Directory of Open Access Journals (Sweden)
Natalia Tukhareli
2011-07-01
Full Text Available Bibliotherapy, as a part of expressive therapy, involves the systematic use of books to help people cope with mental, physical, emotional, or social problems. It has been widely recognized as an approach that holds great promise in helping librarians to better address emotional, behavioural and socials concerns of various groups of people. The benefits of bibliotherapeutic services such as reading groups, expanded readers’ advisory, books-on-prescription and information-on-prescription services as well as various outreach programs are well documented in the library literature. On the other hand, health professionals who work in cooperation with educators and librarians share medical records on the healing and consoling power of books. The paper will explore the role of bibliotherapy in a library setting and identify particular bibliotherapeutic schemes to be used when serving people affected by HIV/AIDS. The paper will provide an overview of the library project developed to address educational and recreational needs of the African people living with HIV/AIDS. The project was successfully implemented at the Nkosi’s Haven Library in Johannesburg, South Africa in 2010. Although the project targeted all the residents of Nkosi’s Haven, the paper will focus mostly on the part of the program developed for children and young adults. The paper will identify psychological and social factors that affect the targeted group of children within the African environment. Particularly, it will highlight a negative effect that stigmatization around the disease has on the lives of the HIV-infected individuals and their families. Within this context, bibliotherapy is seen as an effective way of reaching out and breaking the isolation of people, especially children living with HIV/AIDS. The paper will describe specific activities strategically chosen for the bibliotherapy sessions to provide a channel through which the participants of the program could analyze

The meaning of spasticity to people with multiple sclerosis: what can health professionals learn?
Morley, Alex; Tod, Angela; Cramp, Mary; Mawson, Sue
2013-07-01
Multiple sclerosis (MS) is the most common disabling neurological condition affecting young adults. One third of people on an American registry of people with MS (PWMS) reported having activities affected by spasticity. The psychosocial effects of spasticity in people with MS have been shown to be distressing and detrimental to emotional and social relationships when investigated from a psychology perspective. This paper investigates the impact of spasticity on the lives of people living with MS from a physiotherapeutic perspective. This study involved 12 semi-structured interviews with individuals experiencing MS-related spasticity. Ten sets of data were analyzed following framework analysis principles. Results suggest spasticity effects life experience of these PWMS in diverse and complex ways. Physical, psychological and social consequences of spasticity are closely linked and can be far reaching. Therapists need to be aware of links between specific physical symptoms and their psychosocial consequences if they want to improve peoples' quality of life. This paper provides in depth qualitative research evidence for the complexity of the spasticity experience for each individual, strengthening the argument for a patient-centred approach to treatment. These results also support the case for targeted interventions with effectiveness recorded in a patient-centred way. • Spasticity is suggested here to affect the lives of individuals with multiple sclerosis in diverse and far reaching ways. Therapists need to investigate this fully in subjective assessment to impact on people's quality of life. • Direct links were identified between treatable physical symptoms and far reaching consequences of spasticity. • Knowledge about the complexity of the spasticity experience for each individual will allow therapists to target interventions appropriately and accurately record effectiveness in a patient-centred way.

The profile of attention differs between locations orthogonal to and in line with reach direction.
Stewart, Emma E M; Ma-Wyatt, Anna
2017-11-01
People make movements in a variety of directions when interacting with the world around them. It has been well documented that attention shifts to the goal of an upcoming movement, whether the movement is a saccade or a reach. However, recent evidence suggests that the direction of a movement may influence the spatial spread of attention (Stewart & Ma-Wyatt, 2015, Journal of Vision, 15(5), 10). We investigated whether the spatiotemporal profile of attention differs depending on where that location is situated relative to the direction of movement, and if this pattern is consistent across different movement effectors. We compared attentional facilitation at locations in line with or orthogonal to the movement, for reach-only, reach-plus-saccade, and saccade-only conditions. Results show that the spatiotemporal profile of attention differs across different movement combinations, and is also different at target locations orthogonal to and in line with the movement direction. Specifically, when a reach alone was made, there was a general decrease in attention at all locations during the movement and a general increase in attention at all locations with a saccade only. However, the concurrent reach and saccade condition showed a premovement attentional facilitation at locations orthogonal to movement direction, but not those in line with the movement direction. These results suggest attentional guidance may be more important at differing time points, depending on the type of movement.

Full Text Available Background: Despite the proven effectiveness of colorectal cancer (CRC screening on reduction of CRC mortality, the uptake of CRC screening remains low. Participation rate is one of determinants for the success of organized population-based screening program. This review aims to identify those who are hard-to-reach, and summarize the strategies to increase their screening rate from individual, provider and system levels. Methods: A systematic search of electronic English databases was conducted on the factors and strategies of uptake in CRC screening for the hard-to-reach population up to May 2017. Discussion: The coverage rate and participation rate are two indexes to identify the hard-to-reach population in organized CRC screening program. However, the homeless, new immigrants, people with severe mental illness, the jail intimates, and people with characteristics including lower education levels and/or low socioeconomic status, living in rural/remote areas, without insurance, and racial minorities are usually recognized as hard-to-reach populations. For them, organized screening programs offer a better coverage, while novel invitation approaches for eligible individuals and multiple strategies from primary care physicians are still needed to enhance screening rates among subjects who are hard-to-reach. Suggestions implied the effectiveness of interventions at the system level, including linkages to general practice; use of decision making tools; enlisting supports from coalition; and the continuum from screening to diagnosis and treatment. Conclusion: Organized CRC screening offers a system access to approach the hard-to-reach populations. To increase their uptake, multiple and novel strategies from individual, provider and system levels should be applied. For policymakers, public healthcare providers and community stakeholders, it is a test to tailor their potential needs and increase their participation rates through continuous efforts to

Ana Angélica Ribeiro de Lima
Full Text Available Abstract Introduction: Functional reach (FR and lateral reach (LR tests are widely used in scientific research and clinical practice. Assessment tools are useful in assessing subjects with greater accuracy and are usually adapted according to the limitations of each condition. Objective: To adapt FR and LR tests for use in an aquatic environment and assess the performance of healthy young adults. Methods: We collected anthropometric data and information on whether the participant exercised regularly or not. The FR and LR tests were adapted for use in an aquatic environment and administered to 47 healthy subjects aged 20-30 years. Each test was repeated three times. Results: Forty-one females and six males were assessed. The mean FR test score for men was 24.06 cm, whereas the mean value for right lateral reach (RLR was 10.94 cm and for left lateral reach (LLR was 9.78 cm. For females, the mean FR score was 17.57 cm, while the mean values for RLR was 8.84cm and for LLR was 7.76 cm. Men performed better in the FR (p < 0.001 and RLR tests than women (p = 0.037. Individuals who exercised regularly showed no differences in performance level when compared with their counterparts. Conclusion: The FR and LR tests were adapted for use in an aquatic environment. Males performed better on the FR and RLR tests, when compared to females. There was no correlation between the FR and LR tests and weight, height, Body Mass Index (BMI, foot length or length of the dominant upper limb.

Full Text Available The effect of the crisis is often multiple on people in rural poverty that secluded and away from the reach of government. Main factor cannot be ignored in crisis is communication. Prolonged crisis will occur when the channels of communication in society clogged. This study establishes three specific targets: (1 To obtain a comprehensive overview of the rural poor people’s knowledge about the crisis and the potential impact, (2 To discover crisis problems faced by the rural people poor, (3 To enlist communication problems in a crisis situation. This study used a qualitative method with a case study approach. Research data collect by conducting FGD of 40 informants selected based on purposive sampling, furthermore eight people were interviewed in depth, plus other supporting informant. The results of the research show people on those two locations have understood the crisis based on their experience of dealing with it. They believe the economic crisis as the first aspect that must be resolved. The completion of crisis should consider indigenous wisdom to avoid a new crisis.

Grace Elisabeth Spencer
2008-07-01
Full Text Available Drawing upon current socio-cultural understandings of risk, this study highlights the disjunction between the expert risk discourses that permeate official public health policy and practice, and young people’s own perspectives on health and risk. Data were collected from young people aged 14-16 years through the use of group and individual interviews in a school and community youth centre setting. Findings from this study question the saliency of expert-defined health-related risks to young people’s everyday lives. Young people in this study saw health as closely linked to ‘being happy’. Friendships and a sense of personal achievement were particularly important to participants’ health and well-being. When accounting for their participation in health-related practices identified as ‘risky’ in government policy – such as smoking, alcohol and substance use – young people emphasised the levels of pressure they experienced. Sources of pressure included arguments and bullying, school work, and negative stereotypes of young people in general. These areas indicated young people’s concerns that reach beyond the official prescriptions permeating current health policy.

Full Text Available Thousands of social gatherings - online communities – occur via ICTs across the Internet. They use listservers, bulletin boards, instant messaging, blogs, social network and meeting facilitation systems and purpose-build platforms. Each community is the product of a complex set of interacting variables. Some of these variables come from usability of the software but social factors have a strong influence. Direct cause and effect relationships are often difficult to tease out and identifying criteria for successful online communities can be difficult. Furthermore several disciplines own this topic, each with its own theories, research methods, community of researchers and publication outlets. This is good for multidisciplinary research but it can be challenging. In this paper I discuss two research projects. Each focuses on community populations that are hard to reach. The first analyses why people do not actively participate in online discussions, i.e., lurk. The second is a new project to develop cross-cultural online book communities for children across the world who do not speak each other’s languages. I present the key findings from each project and suggest ways of working with these hard to reach populations.

Full Text Available Experimental evidence suggests the existence of a sophisticated brain circuit specifically dedicated to reach-to-grasp planning and execution, both in human and non human primates (Castiello, 2005. Studies accomplished by means of neuroimaging techniques suggest the hypothesis of a dichotomy between a reach-to-grasp circuit, involving the intraparietal area (AIP, the dorsal and ventral premotor cortices (PMd and PMv - Castiello and Begliomini, 2008; Filimon, 2010 and a reaching circuit involving the medial intraparietal area (mIP and the Superior Parieto-Occipital Cortex (SPOC (Culham et al., 2006. However, the time course characterizing the involvement of these regions during the planning and execution of these two types of movements has yet to be delineated. A functional magnetic resonance imaging (fMRI study has been conducted, including reach-to grasp and reaching only movements, performed towards either a small or a large stimulus, and Finite Impulse Response model (FIR - Henson, 2003 was adopted to monitor activation patterns from stimulus onset for a time window of 10 seconds duration. Data analysis focused on brain regions belonging either to the reaching or to the grasping network, as suggested by Castiello & Begliomini (2008.Results suggest that reaching and grasping movements planning and execution might share a common brain network, providing further confirmation to the idea that the neural underpinnings of reaching and grasping may overlap in both spatial and temporal terms (Verhagen et al., 2013.

REACH: impact on the US cosmetics industry?
Pouillot, Anne; Polla, Barbara; Polla, Ada
2009-03-01
The Registration, Evaluation, Authorization and restriction of Chemicals (REACH) is a recent European regulation on chemical substances meant to protect human health and the environment. REACH imposes the "precautionary principle" where additional data and definitive action are required when uncertainty is identified. The cosmetics industry is only partially concerned by REACH: while the stages of registration and evaluation apply to cosmetics, those of authorization and restriction most likely will not, as cosmetic ingredients are already subject to regulation by various agencies and directives. REACH has potential benefits to the industry including the possibility of reassuring consumers and improving their image of chemicals and cosmetics. However, REACH also has potential disadvantages, mainly with regard to impeding innovation. The American cosmetics industry will be affected by REACH, because all US manufacturers who export substances to Europe will have to fully comply with REACH.

Models of Self in Families of People with Spina Bifida
Directory of Open Access Journals (Sweden)
Viviam Rafaela Barbosa Pinheiro Freire
Full Text Available Abstract: Models of self reveal cultural views regarding the competences that children should acquire, and these views tend to be shared by people within the same environment. Thus, this study aims to evaluate the models of self in families of people with spina bifida. Seventeen caregivers answered an online questionnaire containing socio-demographic questions and three scales of self: autonomous, related and autonomous-related. The data were analyzed using descriptive statistics and techniques of multivariate analysis. The main results indicate that the most valued model of self was the autonomous-related model, reflecting the desire that children develop autonomy as well as interpersonal relationships. Such a model, however, is distinct from that of family groups of people with typical development living in the same cultural environment, indicating the need for families of people with spina bifida to receive support to reach their developmental goals.

The long reach of Alzheimer's disease: patients, practice, and policy.
Bynum, Julie P W
2014-04-01
The impact of Alzheimer's disease and related dementias reaches well beyond the health care needs of the person with dementia. As dementia inexorably progresses, the patient becomes increasingly dependent on others for basic daily care and routine tasks, a physically safe environment, and protection from exploitation or abuse. Addressing the diverse medical and social care needs of the burgeoning US population with Alzheimer's disease and related dementias requires the adoption of a broad-based policy framework and agenda that explicitly acknowledge the complex and unique needs of people with dementia and the impacts of dementia on caregivers and society at large. Public policies related to social service providers, agencies that provide appropriate housing, financial and legal services, and law enforcement must complement other policies focused on prevention and risk reduction, effective treatment development, and efficient health care delivery.

The database for reaching experiments and models.
Directory of Open Access Journals (Sweden)
Ben Walker
Full Text Available Reaching is one of the central experimental paradigms in the field of motor control, and many computational models of reaching have been published. While most of these models try to explain subject data (such as movement kinematics, reaching performance, forces, etc. from only a single experiment, distinct experiments often share experimental conditions and record similar kinematics. This suggests that reaching models could be applied to (and falsified by multiple experiments. However, using multiple datasets is difficult because experimental data formats vary widely. Standardizing data formats promises to enable scientists to test model predictions against many experiments and to compare experimental results across labs. Here we report on the development of a new resource available to scientists: a database of reaching called the Database for Reaching Experiments And Models (DREAM. DREAM collects both experimental datasets and models and facilitates their comparison by standardizing formats. The DREAM project promises to be useful for experimentalists who want to understand how their data relates to models, for modelers who want to test their theories, and for educators who want to help students better understand reaching experiments, models, and data analysis.

A reach and get technique includes invoking a reach command from a reach location within a computing environment. A user can then navigate to an object within the computing environment and invoke a get command on the object. In response to invoking the get command, the computing environment is automatically navigated back to the reach location and the object copied into the reach location.

Health research on transgender people has been hampered by the challenges inherent in studying a hard-to-reach, relatively small, and geographically dispersed population. The Internet has the potential to facilitate access to transgender samples large enough to permit examination of the diversity and syndemic health disparities found among this population. In this article, we describe the experiences of a team of investigators using the Internet to study HIV risk behaviors of transgender people in the United States. We developed an online instrument, recruited participants exclusively via websites frequented by members of the target population, and collected data using online quantitative survey and qualitative synchronous and asynchronous interview methods. Our experiences indicate that the Internet environment presents the investigator with some unique challenges and that commonly expressed criticisms about Internet research (e.g., lack of generalizable samples, invalid study participants, and multiple participation by the same subject) can be overcome with careful method design, usability testing, and pilot testing. The importance of both usability and pilot testing are described with respect to participant engagement and retention and the quality of data obtained online.

Seventy-six men (mean age ± SD: 23.45 ± 3.96 years and 67 women (mean age ± SD: 23.85 ± 5.36 years were asked to perform three trials of SR, BS left (BSl, right (BSr, and passive straight leg raise (PSLR right and left (hamstring criterion measure in a randomized order. The thoracic, lumbar, and pelvis angles (measured with a Uni-level inclinometer and forward reach scores were recorded once the subjects reached forward as far as possible without flexing the knees. A repeated measure ANOVA was performed followed by Bonferroni´s post hoc test. Pearson correlation coefficients were used to define the relationships between SR and BS scores with respect to PSLR. In both men and women, the thoracic angle in BS was significantly greater than in SR (p<0.016. However, no significant differences were found between the tests in lumbar angle, pelvic angle, and forward reach scores. The concurrent validity of the forward reach score as a measure of hamstring extensibility was moderate in women (0.66 0. 76 and weak to moderate in men (0.51 0.59. The concurrent validity was slightly higher in SR than in BS, although no significant differences between the correlation values were observed. There were significant differences in the thoracic angle between the SR and BS, but not in the forward reach score. There was no difference in concurrent validity between the two tests. However, the traditional SR was preferred because it reached better concurrent validity than the BS

Full Text Available BACKGROUND: In 2009 an estimated 5.3 million people in the United States were afflicted with Alzheimer's disease, a degenerative form of dementia. The impact of this disease is not limited to the patient but also has significant impact on the lives and health of their family caregivers. The Resources for Enhancing Alzheimer's Caregiver Health (REACH II program was developed and tested in clinical studies. The REACH II program is now being delivered by community agencies in several locations. This study examines the impact of the REACH II program on caregiver lives and health in a city in north Texas. STUDY DESIGN: Family caregivers of Alzheimer's patients were assessed using an instrument covering the multi-item domains of Caregiver Burden, Depression, Self-Care, and Social Support upon enrollment in the program and at the completion of the 6 month intervention. The domain scores were analyzed using a multivariate paired t-test and Bonferroni confidence interval for the differences in pre- and post-service domain scores. RESULTS: A total of 494 families were enrolled in the program during the period January 1, 2011 through June 30, 2012. Of these families 177 completed the 6 month program and have pre - and post service domain scores. The median age for the caregivers was 62 years. The domain scores for Depression and Caregiver Burden demonstrated statistically significant improvements upon program completion. CONCLUSION: The REACH II intervention was successfully implemented by a community agency with comparable impacts to those of the clinical trial warranting wider scale implementation.

[Aging and quality of life: challenges and opportunities for people with intellectual disabilities].
Schäper, S; Graumann, S
2012-10-01
In the coming years, a growing number of people with an intellectual disability will reach retirement age. In line with the change of paradigms, the leading ideas of participation, inclusion and self-determination have become the principles of the ideological and conceptual framework in social services for people with disabilities. However, in many places convincing concepts and arrangements of support for elderly people with intellectual disabilities are lacking, particularly beyond institutionalized concepts. The research project "Lebensqualität inklusiv(e)" (quality of life included) tries to bridge this gap. On the base of an estimation of the demographic development for this group of people, models of best practice have been documented and evaluated focusing on living conditions and the special requirements for elderly people with intellectual disabilities in order to gather ideas for the development of arrangements of support. The results show that an interdisciplinary cooperation is indispensable.

Alcohol consumption by adolescents and young adults is an issue of significant public concern. Internet-based Social Networking sites, such as Facebook, are potential avenues to reach young people easily. to underline the innovation in proposing surveys to collect health-related information regarding young people alcohol consumption and other substances abuse by using Social Networking Websites, particularly Facebook. A questionnaire investigating modalities of alcohol consumption, drinking patterns' risk behaviors and other substances abuse was proposed through a "Facebook event" to young Italian Facebook users aged between 16 and 32. Each Facebook user invited to the event was free to participate, to answer to the questionnaire and to invite his "Facebook friends". During the 89 days of permanence on the Social Network, 1846 Facebook users participated the event and 732 of them decided spontaneously to answer the questionnaire. The frequency of answering was 8.2 people per day. About 200 users wrote a positive comment to the initiative on the wall of the event. Sixty% of subjects participating the survey were females. Ninety-one% of people answering the questionnaire were alcohol consumers. More than 50% of alcohol consumers were also smokers. Approximately 50% of subjects were binge drinkers. Illegal drugs were used by the 22.2% of the interviewed people. Facebook resulted an efficient and rapid tool to reach young people from all over Italy and to propose surveys in order to investigate alcohol consumption and alcohol-related health problems in the youth.

Simple Smartphone-Based Guiding System for Visually Impaired People.
Lin, Bor-Shing; Lee, Cheng-Che; Chiang, Pei-Ying
2017-06-13
Visually impaired people are often unaware of dangers in front of them, even in familiar environments. Furthermore, in unfamiliar environments, such people require guidance to reduce the risk of colliding with obstacles. This study proposes a simple smartphone-based guiding system for solving the navigation problems for visually impaired people and achieving obstacle avoidance to enable visually impaired people to travel smoothly from a beginning point to a destination with greater awareness of their surroundings. In this study, a computer image recognition system and smartphone application were integrated to form a simple assisted guiding system. Two operating modes, online mode and offline mode, can be chosen depending on network availability. When the system begins to operate, the smartphone captures the scene in front of the user and sends the captured images to the backend server to be processed. The backend server uses the faster region convolutional neural network algorithm or the you only look once algorithm to recognize multiple obstacles in every image, and it subsequently sends the results back to the smartphone. The results of obstacle recognition in this study reached 60%, which is sufficient for assisting visually impaired people in realizing the types and locations of obstacles around them.

Intelligent Interfaces to Empower People with Disabilities
Betke, Margrit
Severe motion impairments can result from non-progressive disorders, such as cerebral palsy, or degenerative neurological diseases, such as Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), or muscular dystrophy (MD). They can be due to traumatic brain injuries, for example, due to a traffic accident, or to brainstem strokes [9, 84]. Worldwide, these disorders affect millions of individuals of all races and ethnic backgrounds [4, 75, 52]. Because disease onset of MS and ALS typically occurs in adulthood, afflicted people are usually computer literate. Intelligent interfaces can immensely improve their daily lives by allowing them to communicate and participate in the information society, for example, by browsing the web, posting messages, or emailing friends. However, people with advanced ALS, MS, or MD may reach a point when they cannot control the keyboard and mouse anymore and also cannot rely on automated voice recognition because their speech has become slurred.

Elderly people are less able to manipulate objects skilfully than young adults. Although previous studies have examined age-related deterioration of hand movements with a focus on the phase after grasping objects, the changes in the reaching phase have not been studied thus far. We aimed to examine whether changes in hand shape patterns during the reaching phase of grasping movements differ between young adults and the elderly. Ten healthy elderly adults and 10 healthy young adults were examined using the Simple Test for Evaluating Hand Functions and kinetic analysis of hand pre-shaping reach-to-grasp tasks. The results were then compared between the two groups. For kinetic analysis, we measured the time of peak tangential velocity of the wrist and the inter-fingertip distance (the distance between the tips of the thumb and index finger) at different time points. The results showed that the elderly group's performance on the Simple Test for Evaluating Hand Functions was significantly lower than that of the young adult group, irrespective of whether the dominant or non-dominant hand was used, indicating deterioration of hand movement in the elderly. The peak tangential velocity of the wrist in either hand appeared significantly earlier in the elderly group than in the young adult group. The elderly group also showed larger inter-fingertip distances with arch-like fingertip trajectories compared to the young adult group for all object sizes. To perform accurate prehension, elderly people have an earlier peak tangential velocity point than young adults. This allows for a longer adjustment time for reaching and grasping movements and for reducing errors in object prehension by opening the hand and fingers wider. Elderly individuals gradually modify their strategy based on previous successes and failures during daily living to compensate for their decline in dexterity and operational capabilities. © 2017 Japanese Psychogeriatric Society.

Methods: Ten people with a history of traumatic anterior shoulder dislocation and 15 with healthy shoulders volunteered for this study. After viewing targets in space, participants pointed with the unconstrained arm to remembered target locations in space without visual guidance. Nine different targets were located in various planes and heights. Endpoint reaching errors were determined by comparing the finger endpoint position without visual guidance to the target location. Shoulder rotation angle at the endpoint was also compared between groups. Results: Participants with injured shoulders were able to point voluntarily to visually specified targets as accurately as participants with healthy shoulders (1 cm difference. However, participants with injured shoulders showed less shoulder external rotation (average 12° difference at the target location when compared with healthy shoulders. This difference was consistent over a large range of target locations. Conclusion: Individuals with a history of traumatic anterior shoulder dislocation have sufficient kinesthetic information about their upper limb orientation to point accurately to visually specified targets in space. However, individuals with injured shoulders acquired a new motor strategy to reach with less shoulder external rotation, presumably to protect the injured shoulder from recurrent injuries.

The new chemical regulation, REACH (1997/2006/EC), Registration, Evaluation, Authorization and restriction of Chemicals, took effect the 1st of June 2007. The background to this report was the introduction of REACH and the difficulties to understand the implications for ash. The most important consequence of REACH is that all chemical substances that are manufactured, handled and used above one tonne per annum per legal entity shall be registered according to this regulation. The registration includes specifying the chemical, physical, toxicity and ecotoxicity properties of the substance and risk assessing the identified areas of use. The report describes the use of ash in connection to the waste legislation and its planned end-of-waste-criteria, the chemical legislation and the Construction Products Directive. The target audience of this report is companies producing ashes and having a use or seeing a use for its ash. The report describes how to make a REACH registration of ash independent if a company did or did not pre-register ash during 2008. It describes how to change from one ash registration into another if the pre-registration was done for one type of ash but the company changes opinion during the sameness check, i.e. changing SIEF (Appendix A). Taking part in REACH registration projects during 2009-2010 can be advantageous since knowledge and financing are shared. Ash can be REACH registered also in the future but it is important to know that the registration have to be done prior the production and marketing starts. If ash is consider to be a waste the handling is covered by the community and national waste legislation. In Sweden ashes are by and large being regarded as waste, and recycling is risk assessed and permits are given case by case. End-of-waste criteria for different waste material are being elaborated within the EU. Such criteria will among other details cover chemical safety. When a material fulfils the end-of-waste criteria such material

Physical fitness is a crucial variable in people with severe mental illness as these people could be more independent and improve their job opportunities. The present study compared the physical fitness of physically active and inactive people with severe mental illness. Physical fitness was evaluated in sixty-two people with severe mental illness using 11 physical tests that include strength, flexibility, balance and aerobic condition. Significant differences were found between both groups in muscle strength (handgrip test) and balance (single leg balance test and functional reach) with better performance in the group of physically active people. The results of the present study suggest that physical fitness (strength and balance) is higher in people with severe mental illness who practise regular physical activity that those who are inactive people. Physical active people may have a reduced risk of falls and fractures due to their higher levels of physical fitness.

How to Increase Reach and Adherence of Web-Based Interventions: A Design Research Viewpoint.
Ludden, Geke D S; van Rompay, Thomas J L; Kelders, Saskia M; van Gemert-Pijnen, Julia E W C
2015-07-10
Nowadays, technology is increasingly used to increase people's well-being. For example, many mobile and Web-based apps have been developed that can support people to become mentally fit or to manage their daily diet. However, analyses of current Web-based interventions show that many systems are only used by a specific group of users (eg, women, highly educated), and that even they often do not persist and drop out as the intervention unfolds. In this paper, we assess the impact of design features of Web-based interventions on reach and adherence and conclude that the power that design can have has not been used to its full potential. We propose looking at design research as a source of inspiration for new (to the field) design approaches. The paper goes on to specify and discuss three of these approaches: personalization, ambient information, and use of metaphors. Central to our viewpoint is the role of positive affect triggered by well-designed persuasive features to boost adherence and well-being. Finally, we discuss the future of persuasive eHealth interventions and suggest avenues for follow-up research.

Health research on transgender people has been hampered by the challenges inherent in studying a hard-to-reach, relatively small, and geographically dispersed population. The Internet has the potential to facilitate access to transgender samples large enough to permit examination of the diversity and syndemic health disparities found among this population. In this article, we describe the experiences of a team of investigators using the Internet to study HIV risk behaviors of transgender people in the United States. We developed an online instrument, recruited participants exclusively via websites frequented by members of the target population, and collected data using online quantitative survey and qualitative synchronous and asynchronous interview methods. Our experiences indicate that the Internet environment presents the investigator with some unique challenges and that commonly expressed criticisms about Internet research (e.g., lack of generalizable samples, invalid study participants, and multiple participation by the same subject) can be overcome with careful method design, usability testing, and pilot testing. The importance of both usability and pilot testing are described with respect to participant engagement and retention and the quality of data obtained online. PMID:24031157

Adaptive mixed reality rehabilitation (AMRR) is a novel integration of motion capture technology and high-level media computing that provides precise kinematic measurements and engaging multimodal feedback for self-assessment during a therapeutic task. We describe the first proof-of-concept study to compare outcomes of AMRR and traditional upper-extremity physical therapy. Two groups of participants with chronic stroke received either a month of AMRR therapy (n = 11) or matched dosing of traditional repetitive task therapy (n = 10). Participants were right handed, between 35 and 85 years old, and could independently reach to and at least partially grasp an object in front of them. Upper-extremity clinical scale scores and kinematic performances were measured before and after treatment. Both groups showed increased function after therapy, demonstrated by statistically significant improvements in Wolf Motor Function Test and upper-extremity Fugl-Meyer Assessment (FMA) scores, with the traditional therapy group improving significantly more on the FMA. However, only participants who received AMRR therapy showed a consistent improvement in kinematic measurements, both for the trained task of reaching to grasp a cone and the untrained task of reaching to push a lighted button. AMRR may be useful in improving both functionality and the kinematics of reaching. Further study is needed to determine if AMRR therapy induces long-term changes in movement quality that foster better functional recovery.

Outcomes of older adults referred for care management and mental health services through the senior reach gatekeeper model of case finding were examined in this study and compared with the Spokane gatekeeper model Colorado Senior Reach and the Mid-Kansas Senior Outreach (MKSO) programs are the two Senior Reach Gatekeeper programs modeled after the Spokane program, employing the same community education and gatekeeper model and with mental health treatment for elderly adults in need of support. The three mature programs were compared on seniors served isolation, and depression ratings. Nontraditional community gatekeepers were trained and referred seniors in need. Findings indicate that individuals served by the two Senior Reach Gatekeeper programs demonstrated significant improvements. Isolation indicators such as social isolation decreased and depression symptoms and suicide ideation also decreased. These findings for two Senior Reach Gatekeeper programs demonstrate that the gatekeeper approach to training community partners worked in referring at-risk seniors in need in meeting their needs, and in having a positive impact on their lives.

Full Text Available Recent reports indicate that Facebook (FB may facilitate recruitment of hard to reach participants into mental health research. The present study aimed to contribute to this emerging literature by exploring recruitment data from a recently completed trial of online treatment for symptoms of anxiety and depression that targeted Arab people. The present study compared traditional recruitment strategies such as media releases, emails, and print advertisements with Facebook strategies including boosting posts, promoting websites, events and FB public fan pages. The main outcomes of interest were the number of started applications and the time and cost per application associated with the FB and traditional recruitment strategies. A target sample of 350 was sought and a total of 81 participants applied to participate over the 42-week recruitment period. Overall, 86% of the resultant applications occurred via FB recruitment and a Poisson regression analysis indicated the FB strategies were more time-effective, recruiting participants 2.5 times faster than the traditional strategies. However, there were no differences in cost-effectiveness for FB ($US37 per participant and traditional strategies ($US40 per participant. The findings of the current study add to existing literature detailing the value of FB recruitment strategies, alongside more traditional strategies, as a way of recruiting hard-to-reach populations for research. However, more research is needed to explore alternative and optimal strategies for the successful recruitment of hard to reach populations via FB and other online social media platforms.

To explore and describe health professionals' experience of working with return to work (RTW) in multimodal rehabilitation for people with non-specific back pain. An interview study using qualitative content analysis. Fifteen participants were interviewed, all were working with multimodal rehabilitation for people with non-specific back pain in eight different rehabilitation units. The participants experienced RTW as a long-term process reaching beyond the time frames of the multimodal rehabilitation (MMR). Their attitudes and, their patients' condition, impacted on their work which focused on psychological and physical well-being as well as participation in everyday life. They often created an action plan for the RTW process, however the responsibility for its realisation was transferred to other actors. The participants described limited interventions in connection with patients' workplaces. Recommended support in the RTW process in MMR comprises the provision of continuous supervision of vocational issues for the health care professionals, the development of guidelines and a checklist for how to work in close collaboration with patients' workplaces and employers, the provision of long-term follow-up in relation to the patients' work, and the development of proper interventions in order to promote transitions between all the different actors involved. Rehabilitation programs targeting return to work (RTW) for people with non-specific back pain needs to include features concretely focusing on vocational issues. Health and RTW is often seen as a linear process in which health comes before RTW. Rehabilitation programs could be tailored to better address the reciprocal relationship between health and work, in which they are interconnected and affect each other. The RTW process is reaching beyond the time frames of the multimodal rehabilitation but further support from the patients are asked for. The rehabilitation programs needs to be designed to provide long

Runeson (Scandanavian Journal of Psychology 18:172-179, 1977) suggested that the polar planimeter might serve as an informative model system of perceptual mechanism. The key aspect of the polar planimeter is that it registers a higher order property of the environment without computational mediation on the basis of lower order properties, detecting task-specific information only. This aspect was posited as a hypothesis for the perception of jumping and reaching affordances for the self and another person. The findings supported this hypothesis. The perception of reaching while jumping significantly differed from an additive combination of jump-without-reaching and reach-without-jumping perception. The results are consistent with Gibson's (The senses considered as perceptual systems, Houghton Mifflin, Boston, MA; Gibson, The senses considered as perceptual systems, Houghton Mifflin, Boston, MA, 1966; The ecological approach to visual perception, Houghton Mifflin, Boston, MA; Gibson, The ecological approach to visual perception, Houghton Mifflin, Boston, MA, 1979) theory of information-that aspects of the environment are specified by patterns in energetic media.

Increasing levels of carbon dioxide in the atmosphere put shallow, warm-water coral reef ecosystems, and the people who depend upon them at risk from two key global environmental stresses: 1) elevated sea surface temperature (that can cause coral bleaching and related mortality), and 2) ocean acidification. These global stressors: cannot be avoided by local management, compound local stressors, and hasten the loss of ecosystem services. Impacts to people will be most grave where a) human dependence on coral reef ecosystems is high, b) sea surface temperature reaches critical levels soonest, and c) ocean acidification levels are most severe. Where these elements align, swift action will be needed to protect people's lives and livelihoods, but such action must be informed by data and science. Designing policies to offset potential harm to coral reef ecosystems and people requires a better understanding of where CO2-related global environmental stresses could cause the most severe impacts. Mapping indicators has been proposed as a way of combining natural and social science data to identify policy actions even when the needed science is relatively nascent. To identify where people are at risk and where more science is needed, we map indicators of biological, physical and social science factors to understand how human dependence on coral reef ecosystems will be affected by globally-driven threats to corals expected in a high-CO2 world. Western Mexico, Micronesia, Indonesia and parts of Australia have high human dependence and will likely face severe combined threats. As a region, Southeast Asia is particularly at risk. Many of the countries most dependent upon coral reef ecosystems are places for which we have the least robust data on ocean acidification. These areas require new data and interdisciplinary scientific research to help coral reef-dependent human communities better prepare for a high CO2 world.

Lack of diversity among study participants in clinical research limits progress in eliminating health disparities. The engagement of lay stakeholders, such as patient or community advisory boards (CABs), has the potential to increase recruitment and retention of underrepresented groups by providing a structure for gathering feedback on research plans and materials from this target population. However, many CABs intentionally recruit prominent stakeholders who are connected to or comfortable with research and academia and thus may not accurately represent the perspectives of underrepresented groups who have been labeled hard-to-reach, including racial minorities and low-income or low-literacy populations. We developed a partnership between the University of Wisconsin-Madison School of Nursing and two community centers to deliberately engage hard-to-reach people in two lay advisory groups, the Community Advisors on Research Design and Strategies (CARDS)®. Community center staff recruited the CARDS from center programs, including parenting and childcare programs, women's support groups, food pantries, and senior meal programs. The CARDS model differs from other CABs in its participants, processes, and outcomes. Since 2010, the CARDS have met monthly with nurses and other researchers, helping them understand how research processes and the language, tone, appearance, and organization of research materials can discourage people from enrolling in clinical studies. We have successfully used the CARDS model to bring hard-to-reach populations into the research process and have sustained their participation. The model represents a promising strategy for increasing the diversity of participants in clinical research. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Full Text Available This study is aimed to understand transgender aging context in Brazil. Normal and abnormal were especially created by biological sciences. For being considered deviants, transgender people are not seen as human beings. They end up living in violent environments. Their life expectancy is low. Many of them do not believe to reach old age. They face a lot of prejudice and death threat. Those who get to what we call old age are considered survivals. This investigation was able to show satisfactorily their demands and needs. To be considered visible, they have to count on public policies to give them existence since their childhood. That way, we believe they will reach what we call old age with respect and dignity, already assured by the Universal Human Rights.

Current mass vaccination campaigns in measles outbreak response are nonselective with respect to the immune status of individuals. However, the heterogeneity in immunity, due to previous vaccination coverage or infection, may lead to potential bias of such campaigns toward those with previous high access to vaccination and may result in a lower-than-expected effective impact. During the 2010 measles outbreak in Malawi, only 3 of the 8 districts where vaccination occurred achieved a measureable effective campaign impact (i.e., a reduction in measles cases in the targeted age groups greater than that observed in nonvaccinated districts). Simulation models suggest that selective campaigns targeting hard-to-reach individuals are of greater benefit, particularly in highly vaccinated populations, even for low target coverage and with late implementation. However, the choice between targeted and nonselective campaigns should be context specific, achieving a reasonable balance of feasibility, cost, and expected impact. In addition, it is critical to develop operational strategies to identify and target hard-to-reach individuals. PMID:24131555

Applying attachment theory to effective practice with hard-to-reach youth: the AMBIT approach.
Bevington, Dickon; Fuggle, Peter; Fonagy, Peter
2015-01-01
Adolescent Mentalization-Based Integrative Treatment (AMBIT) is a developing approach to working with "hard-to-reach" youth burdened with multiple co-occurring morbidities. This article reviews the core features of AMBIT, exploring applications of attachment theory to understand what makes young people "hard to reach," and provide routes toward increased security in their attachment to a worker. Using the theory of the pedagogical stance and epistemic ("pertaining to knowledge") trust, we show how it is the therapeutic worker's accurate mentalizing of the adolescent that creates conditions for new learning, including the establishment of alternative (more secure) internal working models of helping relationships. This justifies an individual keyworker model focused on maintaining a mentalizing stance toward the adolescent, but simultaneously emphasizing the critical need for such keyworkers to remain well connected to their wider team, avoiding activation of their own attachment behaviors. We consider the role of AMBIT in developing a shared team culture (shared experiences, shared language, shared meanings), toward creating systemic contexts supportive of such relationships. We describe how team training may enhance the team's ability to serve as a secure base for keyworkers, and describe an innovative approach to treatment manualization, using a wiki format as one way of supporting this process.

REACH: next step to a sound chemicals management.
Van der Wielen, Arnold
2007-12-01
REACH is the new European Regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals. It entered into force on 1st June 2007 to streamline and improve the former legislative framework on new and on existing chemical substances of the European Union. Companies which manufacture or import more than 1 tonne of a substance per year will be required to register the substance at the new EU Chemicals Agency located in Helsinki. REACH places greater responsibility on industry to manage the risks that chemicals may pose to the health and the environment and to provide safety information that will be passed down the supply chain. In principle, REACH applies to all chemicals as such, as components in preparations and as used in articles. REACH is a radical step forward in the EU chemicals management. The onus will move from the authorities to industry. In addition, REACH will allow the further evaluation of substances where there are grounds for concern, foresees an authorisation system for the use of substances of very high concern and a system of restrictions, where applicable, for substances of concern. The Authorisation system will require companies to switch progressively to safer alternatives where a suitable alternative exists. Current use restrictions will remain under REACH system.

More than 40 major wars took place during the past decade. The origins and the warlike means that were engaged were very different from those of older conflicts. Wars between nations are less numerous. They have been replaced by civilian wars that are more rooted on cultural and religious grounds than on economic interests alone. During this short period of time, warfare was responsible for about 2 millions of direct deaths and 20 millions displaced people and refugees. The injured and victims of starvation and epidemics were innumerable and awaited for civilian medical help.

Can Seeking Happiness Make People Happy? Paradoxical Effects of Valuing Happiness
Mauss, Iris B.; Tamir, Maya; Anderson, Craig L.; Savino, Nicole S.
2011-01-01
Happiness is a key ingredient of well-being. It is thus reasonable to expect that valuing happiness will have beneficial outcomes. We argue that this may not always be the case. Instead, valuing happiness could be self-defeating because the more people value happiness, the more likely they will feel disappointed. This should apply particularly in positive situations, in which people have every reason to be happy. Two studies support this hypothesis. In Study 1, female participants who valued happiness more (vs. less) reported lower happiness when under conditions of low, but not high, life stress. In Study 2, compared to a control group, female participants who were experimentally induced to value happiness reacted less positively to a happy, but not a sad, emotion induction. This effect was mediated by participants’ disappointment at their own feelings. Paradoxically, therefore, valuing happiness may lead people to be less happy just when happiness is within reach.

Peer Support for the Hardly Reached: A Systematic Review.
Sokol, Rebeccah; Fisher, Edwin
2016-07-01
Health disparities are aggravated when prevention and care initiatives fail to reach those they are intended to help. Groups can be classified as hardly reached according to a variety of circumstances that fall into 3 domains: individual (e.g., psychological factors), demographic (e.g., socioeconomic status), and cultural-environmental (e.g., social network). Several reports have indicated that peer support is an effective means of reaching hardly reached individuals. However, no review has explored peer support effectiveness in relation to the circumstances associated with being hardly reached or across diverse health problems. To conduct a systematic review assessing the reach and effectiveness of peer support among hardly reached individuals, as well as peer support strategies used. Three systematic searches conducted in PubMed identified studies that evaluated peer support programs among hardly reached individuals. In aggregate, the searches covered articles published from 2000 to 2015. Eligible interventions provided ongoing support for complex health behaviors, including prioritization of hardly reached populations, assistance in applying behavior change plans, and social-emotional support directed toward disease management or quality of life. Studies were excluded if they addressed temporally isolated behaviors, were limited to protocol group classes, included peer support as the dependent variable, did not include statistical tests of significance, or incorporated comparison conditions that provided appreciable social support. We abstracted data regarding the primary health topic, categorizations of hardly reached groups, program reach, outcomes, and strategies employed. We conducted a 2-sample t test to determine whether reported strategies were related to reach. Forty-seven studies met our inclusion criteria, and these studies represented each of the 3 domains of circumstances assessed (individual, demographic, and cultural-environmental). Interventions

Do working environment interventions reach shift workers?
Nabe-Nielsen, Kirsten; Jørgensen, Marie Birk; Garde, Anne Helene; Clausen, Thomas
2016-01-01
Shift workers are exposed to more physical and psychosocial stressors in the working environment as compared to day workers. Despite the need for targeted prevention, it is likely that workplace interventions less frequently reach shift workers. The aim was therefore to investigate whether the reach of workplace interventions varied between shift workers and day workers and whether such differences could be explained by the quality of leadership exhibited at different times of the day. We used questionnaire data from 5361 female care workers in the Danish eldercare sector. The questions concerned usual working hours, quality of leadership, and self-reported implementation of workplace activities aimed at stress reduction, reorganization of the working hours, and participation in improvements of working procedures or qualifications. Compared with day workers, shift workers were less likely to be reached by workplace interventions. For example, night workers less frequently reported that they had got more flexibility (OR 0.5; 95 % CI 0.3-0.7) or that they had participated in improvements of the working procedures (OR 0.6; 95 % CI 0.5-0.8). Quality of leadership to some extent explained the lack of reach of interventions especially among fixed evening workers. In the light of the evidence of shift workers' stressful working conditions, we suggest that future studies focus on the generalizability of results of the present study and on how to reach this group and meet their needs when designing and implementing workplace interventions.

Action plans can interact to hinder or facilitate reach performance.
Fournier, Lisa R; Wiediger, Matthew D; Taddese, Ezana F
2015-11-01
Executing a reach action can be delayed while retaining another action in working memory (WM) if the two action plans partly overlap rather than do not overlap. This delay (partial repetition cost) occurs when reach responses are under cognitive control. In this study, we investigated whether facilitation (a partial repetition benefit) occurs when reach responses are automatic. We also examined whether the hemisphere controlling the limb or selection of the preferred limb (based on a free-reach task) influences reach performance when the actions partly overlap. Left- and right-handers reached to different stimulus locations to the left and right of body midline with their ipsilateral hand while maintaining an action plan in WM that required the same or the different hand. The results showed a partial repetition benefit for spatially compatible reaches to left and right stimulus locations far from the body midline, but not for those near the body midline. Also, no partial repetition cost was found at any of the stimulus-reach locations. This indicates that automatic reach responses that partly overlap with an action plan maintained in WM are not delayed, but instead can be facilitated (partial repetition benefit). The roles of hemisphere and reach-hand preference in action control and the importance of the degree of feature overlap in obtaining a partial repetition benefit (and cost) are discussed.

Task-dependent vestibular feedback responses in reaching.
Keyser, Johannes; Medendorp, W Pieter; Selen, Luc P J
2017-07-01
When reaching for an earth-fixed object during self-rotation, the motor system should appropriately integrate vestibular signals and sensory predictions to compensate for the intervening motion and its induced inertial forces. While it is well established that this integration occurs rapidly, it is unknown whether vestibular feedback is specifically processed dependent on the behavioral goal. Here, we studied whether vestibular signals evoke fixed responses with the aim to preserve the hand trajectory in space or are processed more flexibly, correcting trajectories only in task-relevant spatial dimensions. We used galvanic vestibular stimulation to perturb reaching movements toward a narrow or a wide target. Results show that the same vestibular stimulation led to smaller trajectory corrections to the wide than the narrow target. We interpret this reduced compensation as a task-dependent modulation of vestibular feedback responses, tuned to minimally intervene with the task-irrelevant dimension of the reach. These task-dependent vestibular feedback corrections are in accordance with a central prediction of optimal feedback control theory and mirror the sophistication seen in feedback responses to mechanical and visual perturbations of the upper limb. NEW & NOTEWORTHY Correcting limb movements for external perturbations is a hallmark of flexible sensorimotor behavior. While visual and mechanical perturbations are corrected in a task-dependent manner, it is unclear whether a vestibular perturbation, naturally arising when the body moves, is selectively processed in reach control. We show, using galvanic vestibular stimulation, that reach corrections to vestibular perturbations are task dependent, consistent with a prediction of optimal feedback control theory.

Mental health in-reach in an urban UK remand prison.
Forrester, Andrew; Singh, Jagmohan; Slade, Karen; Exworthy, Tim; Sen, Piyal
2014-01-01
Prison mental health in-reach teams (MHITs) have developed in England and Wales over the last decade. Services have been nationally reviewed, but detailed descriptions of their work have been scarce. The purpose of this paper is to describe the functions of one MHIT in a busy, ethnically diverse, male remand prison in London, UK. Clinical and demographic data were collected for prisoners referred to the MHIT using a retrospective design over an 18-week period in 2008/2009 (n=111). Foreign national prisoners and sentenced prisoners were significantly under-referred. Most referrals were already known to community mental health services, although around a quarter accessed services for the first time in prison. Around a third presented with self-harm/suicide risks. Substance misuse problems were common. Although the MHIT had evolved systems to promote service access, prisoner self-referrals were limited. Foreign national prisoners require enhanced investment to improve service access. MHITs identify people with mental disorders for the first time in prisons, but better screening arrangements are needed across systems. An evaluation of multiple MHIT models could inform a wider delivery template. Originality/value - One of the first ground-level evaluations of MHITs in England and Wales.

Background The use of reactive strategies to disseminate effective Internet-delivered lifestyle interventions restricts their level of reach within the target population. This stresses the need to invest in proactive strategies to offer these interventions to the target population. The present study used a proactive strategy to increase reach of an Internet-delivered multi component computer tailored intervention, by embedding the intervention in an existing online health monitoring system of the Regional Public Health Services in the Netherlands. Methods The research population consisted of Dutch adults who were invited to participate in the Adult Health Monitor (N = 96,388) offered by the Regional Public Health Services. This Monitor consisted of an online or a written questionnaire. A prospective design was used to determine levels of reach, by focusing on actual participation in the lifestyle intervention. Furthermore, adequacy of reach among the target group was assessed by composing detailed profiles of intervention users. Participants’ characteristics, like demographics, behavioral and mental health status and quality of life, were included in the model as predictors. Results A total of 41,155 (43%) people participated in the Adult Health Monitor, of which 41% (n = 16,940) filled out the online version. More than half of the online participants indicated their interest (n = 9169; 54%) in the computer tailored intervention and 5168 participants (31%) actually participated in the Internet-delivered computer tailored intervention. Males, older respondents and individuals with a higher educational degree were significantly more likely to participate in the intervention. Furthermore, results indicated that especially participants with a relatively healthier lifestyle and a healthy BMI were likely to participate.

People adopt optimal policies in simple decision-making, after practice and guidance.
Evans, Nathan J; Brown, Scott D
2017-04-01
Organisms making repeated simple decisions are faced with a tradeoff between urgent and cautious strategies. While animals can adopt a statistically optimal policy for this tradeoff, findings about human decision-makers have been mixed. Some studies have shown that people can optimize this "speed-accuracy tradeoff", while others have identified a systematic bias towards excessive caution. These issues have driven theoretical development and spurred debate about the nature of human decision-making. We investigated a potential resolution to the debate, based on two factors that routinely differ between human and animal studies of decision-making: the effects of practice, and of longer-term feedback. Our study replicated the finding that most people, by default, are overly cautious. When given both practice and detailed feedback, people moved rapidly towards the optimal policy, with many participants reaching optimality with less than 1 h of practice. Our findings have theoretical implications for cognitive and neural models of simple decision-making, as well as methodological implications.

Coral Reefs and People in a High-CO2 World: Where Can Science Make a Difference to People?

Reefs and People at Risk Increasing levels of carbon dioxide in the atmosphere put shallow, warm-water coral reef ecosystems, and the people who depend upon them at risk from two key global environmental stresses: 1) elevated sea surface temperature (that can cause coral bleaching and related mortality), and 2) ocean acidification. These global stressors: cannot be avoided by local management, compound local stressors, and hasten the loss of ecosystem services. Impacts to people will be most grave where a) human dependence on coral reef ecosystems is high, b) sea surface temperature reaches critical levels soonest, and c) ocean acidification levels are most severe. Where these elements align, swift action will be needed to protect people’s lives and livelihoods, but such action must be informed by data and science. An Indicator Approach Designing policies to offset potential harm to coral reef ecosystems and people requires a better understanding of where CO2-related global environmental stresses could cause the most severe impacts. Mapping indicators has been proposed as a way of combining natural and social science data to identify policy actions even when the needed science is relatively nascent. To identify where people are at risk and where more science is needed, we map indicators of biological, physical and social science factors to understand how human dependence on coral reef ecosystems will be affected by globally-driven threats to corals expected in a high-CO2 world. Western Mexico, Micronesia, Indonesia and parts of Australia have high human dependence and will likely face severe combined threats. As a region, Southeast Asia is particularly at risk. Many of the countries most dependent upon coral reef ecosystems are places for which we have the least robust data on ocean acidification. These areas require new data and interdisciplinary scientific research to help coral reef-dependent human communities better prepare for a high CO2 world. PMID:27828972

THE POINT OF VIEW OF POOR PEOPLE WORKING IN INFORMAL SECTOR ON POVERTY
Directory of Open Access Journals (Sweden)
Gonul ICLI
2010-01-01
Full Text Available Even though the poor with a lower income than poverty line though hired to be paid constitute the majority of the whole population in many countries, they have not been researched sufficiently. Working poor people can not reach the sufficient level of income to meet their expenses as a result of familial circumstances like insufficient education, divorce, excessiveness of the number of children, loss of a spouse as well as working for low wage due to the labour market. This research is supposed to be about poor people working as wage earners in informal sector in Denizli. 100 apartment doorkeepers, 100 house cleaners and 100 baby sitters have been included into the research as its samples. This research is concerned with the point of view about poverty of working poor people, their strategies of coping with poverty and their social relations

The 1994 International Conference on Population and Development proposed increasing contraceptive couple protection from 550 million in 1995 to 880 million in 2015. The task for family planning (FP) programs is to provide access to services for, sometimes, inaccessible rural populations. FP need based on desire for no more children has ranged from under 20% in Senegal to almost 80% in Peru. Socioeconomic development was found not to be a prerequisite for fertility change. Gender inequalities in education and social autonomy must be changed. FP access is very important among women with a disadvantaged background or among women unsure about FP. Bangladesh is a good example of a country with increased contraceptive prevalence despite low income. The rule of thumb is that contraception increases of 15% contribute to a drop in family size of about one child. Program effectiveness is related to a variety of factors: contraceptive availability at many locations, acceptable price of contraception, delivery of the oral contraceptives without prescriptions, and other strategies. FP is a service not a medical treatment. A range of methods must be promoted and available from a range of facilities. Contraceptive use is dependent on the woman's stage in her lifecycle and is dependent on informed choice. Community-based distribution systems are effective, whereas free distribution by poorly-trained field workers is not always very effective because patient payment of all or part of the cost assures quality and freedom of choice. Effective programs for underprivileged groups involve aggressive, easy to manage programs that can be replicated rapidly. FP serves a useful function in depressing maternal mortality among the poor in Africa, who have no access to quality health services. Social marketing is an effective strategy for reaching remote areas. Political will and robust management are necessary commodities.

Cerebellar inactivation impairs memory of learned prism gaze-reach calibrations.
Norris, Scott A; Hathaway, Emily N; Taylor, Jordan A; Thach, W Thomas
2011-05-01
Three monkeys performed a visually guided reach-touch task with and without laterally displacing prisms. The prisms offset the normally aligned gaze/reach and subsequent touch. Naive monkeys showed adaptation, such that on repeated prism trials the gaze-reach angle widened and touches hit nearer the target. On the first subsequent no-prism trial the monkeys exhibited an aftereffect, such that the widened gaze-reach angle persisted and touches missed the target in the direction opposite that of initial prism-induced error. After 20-30 days of training, monkeys showed long-term learning and storage of the prism gaze-reach calibration: they switched between prism and no-prism and touched the target on the first trials without adaptation or aftereffect. Injections of lidocaine into posterolateral cerebellar cortex or muscimol or lidocaine into dentate nucleus temporarily inactivated these structures. Immediately after injections into cortex or dentate, reaches were displaced in the direction of prism-displaced gaze, but no-prism reaches were relatively unimpaired. There was little or no adaptation on the day of injection. On days after injection, there was no adaptation and both prism and no-prism reaches were horizontally, and often vertically, displaced. A single permanent lesion (kainic acid) in the lateral dentate nucleus of one monkey immediately impaired only the learned prism gaze-reach calibration and in subsequent days disrupted both learning and performance. This effect persisted for the 18 days of observation, with little or no adaptation.

Objective. Despite the high number of degrees of freedom of the human hand, most actions of daily life can be executed incorporating only palmar, pincer and lateral grasp. In this study we attempt to discriminate these three different executed reach-and-grasp actions utilizing their EEG neural correlates. Approach. In a cue-guided experiment, 15 healthy individuals were asked to perform these actions using daily life objects. We recorded 72 trials for each reach-and-grasp condition and from a no-movement condition. Main results. Using low-frequency time domain features from 0.3 to 3 Hz, we achieved binary classification accuracies of 72.4%, STD ± 5.8% between grasp types, for grasps versus no-movement condition peak performances of 93.5%, STD ± 4.6% could be reached. In an offline multiclass classification scenario which incorporated not only all reach-and-grasp actions but also the no-movement condition, the highest performance could be reached using a window of 1000 ms for feature extraction. Classification performance peaked at 65.9%, STD ± 8.1%. Underlying neural correlates of the reach-and-grasp actions, investigated over the primary motor cortex, showed significant differences starting from approximately 800 ms to 1200 ms after the movement onset which is also the same time frame where classification performance reached its maximum. Significance. We could show that it is possible to discriminate three executed reach-and-grasp actions prominent in people’s everyday use from non-invasive EEG. Underlying neural correlates showed significant differences between all tested conditions. These findings will eventually contribute to our attempt of controlling a neuroprosthesis in a natural and intuitive way, which could ultimately benefit motor impaired end users in their daily life actions.

Determining how the human nervous system contends with neuro-motor noise is vital to understanding how humans achieve accurate goal-directed movements. Experimentally, people learning skilled tasks tend to reduce variability in distal joint movements more than in proximal joint movements. This suggests that they might be imposing greater control over distal joints than proximal joints. However, the reasons for this remain unclear, largely because it is not experimentally possible to directly manipulate either the noise or the control at each joint independently. Therefore, this study used a 2 degree-of-freedom torque driven arm model to determine how different combinations of noise and/or control independently applied at each joint affected the reaching accuracy and the total work required to make the movement. Signal-dependent noise was simultaneously and independently added to the shoulder and elbow torques to induce endpoint errors during planar reaching. Feedback control was then applied, independently and jointly, at each joint to reduce endpoint error due to the added neuromuscular noise. Movement direction and the inertia distribution along the arm were varied to quantify how these biomechanical variations affected the system performance. Endpoint error and total net work were computed as dependent measures. When each joint was independently subjected to noise in the absence of control, endpoint errors were more sensitive to distal (elbow) noise than to proximal (shoulder) noise for nearly all combinations of reaching direction and inertia ratio. The effects of distal noise on endpoint errors were more pronounced when inertia was distributed more toward the forearm. In contrast, the total net work decreased as mass was shifted to the upper arm for reaching movements in all directions. When noise was present at both joints and joint control was implemented, controlling the distal joint alone reduced endpoint errors more than controlling the proximal joint

Conservation reaches new heights.
Pepall, J; Khanal, P
1992-10-01
The conservation program with the management assistance of the Woodlands Mountain Institute in 2 contiguous parks, the Mount Everest National Park in Nepal and the Qomolangma Nature Reserve in China, in 2 countries is described. The focus is on conservation of the complex ecosystem with sustainable development by showing local people how to benefit from the park without environmental damage. Cultural diversity is as important as biological diversity. The area has been designated by UNESCO as a World Heritage Site with the "last pure ecological seed" of the Himalayas. The regional geography and culture are presented. Population growth has impacted natural resources through overgrazing, cultivation of marginal land, and deforestation; future plans to build a dam and road bordering the nature reserve pose other threats. Proposed management plans for the Makalu-Barun Nature Park (established in November 1991) and Conservation Area include a division of the park into nature reserve areas free of human activity, protected areas which permit traditional land use, and special sites and trail for tourists and religious pilgrims. The conservation area will act as a buffer for the park and provide economic opportunities; further subdivisions include land use for biodiversity protection, community forest and pasture, agroforestry, and agriculture and settlement. Efforts will be made to increase the welfare of women and local people; proposed projects include the introduction of higher milk-producing animals for stall feeding. Also proposed is a cultural and natural history museum. 70% of the project's resources will be directed to local community participation in consultation and park maintenance. The project is a model of how conservation and protection of natural resources can coexist with local economic development and participation; an integration of preservation of biological diversity, mountain wisdom, and the value of local people as resources for conservation.

Probing the reaching-grasping network in humans through multivoxel pattern decoding.
Di Bono, Maria Grazia; Begliomini, Chiara; Castiello, Umberto; Zorzi, Marco
2015-11-01
The quest for a putative human homolog of the reaching-grasping network identified in monkeys has been the focus of many neuropsychological and neuroimaging studies in recent years. These studies have shown that the network underlying reaching-only and reach-to-grasp movements includes the superior parieto-occipital cortex (SPOC), the anterior part of the human intraparietal sulcus (hAIP), the ventral and the dorsal portion of the premotor cortex, and the primary motor cortex (M1). Recent evidence for a wider frontoparietal network coding for different aspects of reaching-only and reach-to-grasp actions calls for a more fine-grained assessment of the reaching-grasping network in humans by exploiting pattern decoding methods (multivoxel pattern analysis--MVPA). Here, we used MPVA on functional magnetic resonance imaging (fMRI) data to assess whether regions of the frontoparietal network discriminate between reaching-only and reach-to-grasp actions, natural and constrained grasping, different grasp types, and object sizes. Participants were required to perform either reaching-only movements or two reach-to-grasp types (precision or whole hand grasp) upon spherical objects of different sizes. Multivoxel pattern analysis highlighted that, independently from the object size, all the selected regions of both hemispheres contribute in coding for grasp type, with the exception of SPOC and the right hAIP. Consistent with recent neurophysiological findings on monkeys, there was no evidence for a clear-cut distinction between a dorsomedial and a dorsolateral pathway that would be specialized for reaching-only and reach-to-grasp actions, respectively. Nevertheless, the comparison of decoding accuracy across brain areas highlighted their different contributions to reaching-only and grasping actions. Altogether, our findings enrich the current knowledge regarding the functional role of key brain areas involved in the cortical control of reaching-only and reach-to-grasp actions

We partnered with 3 social service organizations to identify hard-to-reach populations, barriers to reach, and strategies for improving recruitment and retention for Program to Encourage Active, Rewarding Lives (PEARLS), a home-based depression-care management program for elders. We conducted semistructured interviews with staff and former PEARLS participants. All interviews were transcribed verbatim and thematically analyzed. Veterans, African Americans, Filipino men, other immigrants and English-language learners, old-older adults, rural communities, and people with limited education were identified as hard to reach. The themes of trust, cultural appropriateness, meet them where they are, and framing and reframing, cut across barriers to participation in PEARLS and approaches for overcoming these barriers. Research findings will be used to inform technical assistance activities with PEARLS providers, changes to PEARLS program and training materials, and future PEARLS research activities. © The Author 2013.

Many young people at high risk for Chlamydia trachomatis (Ct) are not reached by current sexual health care systems, such as general practitioners and public sexual health care centres (sexually transmitted infection clinics).Ct is the most frequently diagnosed bacterial sexually transmitted infection (STI) among sexually active people and in particular young heterosexuals. Innovative screening strategies are needed to interrupt the transmission of Ct among young people and connect the hidden cases to care. Intervention Mapping (IM), a systematic approach to develop theory- and evidence-based interventions, was used to develop a strategy to target Ct testing towards young people who are currently hidden to care in The Netherlands. Both clinical users (i.e. sexual health care nurses) and public users (i.e., young people at risk for Ct) were closely involved in the IM process. A needs assessment study was carried out using semi-structured interviews among users (N = 21), a literature search and by taking lessons learned from existing screening programmes. Theoretical methods and practical applications to reach high risk young people and influence testing were selected and translated into specific programme components. The IM approach resulted in the development of a secure and web-based outreach Ct screening strategy, named SafeFriend. It is developed to target groups of high-risk young people who are currently hidden to care. Key methods include web-based Respondent Driven Sampling, starting from young Ct positive sexual health care centre clients, to reach and motivate peers (i.e., sex partners and friends) to get tested for Ct. Testing and the motivation of peers were proposed as the desired behavioural outcomes and the Precaution Adoption Process Model was chosen as theoretical framework. End users, i.e., young people and sexual health care nurses were interviewed and included in the development process to increase the success of implementation. IM proved useful

The appearance of people associated with the Lapita culture in the South Pacific ~3,000 years ago1 marked the beginning of the last major human dispersal to unpopulated lands. However, the relationship of these pioneers to the long established Papuans of the New Guinea region is unclear. We report genome-wide ancient DNA data from four individuals from Vanuatu (~3100-2700 years before present) and Tonga (~2700-2300 years before present), and co-analyze them with 778 present-day East Asians and Oceanians. Today, indigenous peoples of the South Pacific harbor a mixture of ancestry from Papuans and a population of East Asian origin that does not exist in unmixed form today, but is a match to the ancient individuals. Most analyses have interpreted the minimum of twenty-five percent Papuan ancestry in the region today as evidence that the first humans to reach Remote Oceania, including Polynesia, were derived from population mixtures near New Guinea, prior to the further expansion into Remote Oceania2–5. However, our finding that the ancient individuals had little to no Papuan ancestry implies later human population movements that spread Papuan ancestry through the South Pacific after the islands’ first peopling.

Growing awareness of health and health care disparities highlights the importance of including information about race, ethnicity, and culture (REC) in health research. Reporting of REC factors in research publications, however, is notoriously imprecise and unsystematic. This article describes the development of a checklist to assess the comprehensiveness and the applicability of REC factor reporting in psychiatric research publications. The 16-itemGAP-REACH© checklist was developed through a rigorous process of expert consensus, empirical content analysis in a sample of publications (N = 1205), and interrater reliability (IRR) assessment (N = 30). The items assess each section in the conventional structure of a health research article. Data from the assessment may be considered on an item-by-item basis or as a total score ranging from 0% to 100%. The final checklist has excellent IRR (κ = 0.91). The GAP-REACH may be used by multiple research stakeholders to assess the scope of REC reporting in a research article. PMID:24080673

The author evaluates two different ways of estimating reach and frequency of plans for printed media. The first assigns reading probabilities to groups of respondents and calculates reach and frequency by simulation. the second estimates parameters to a model for reach/frequency. It is concluded ...... and estiamtes from such models are shown to be closer to panel data. the problem, however, is to get valid input for such models from readership surveys. Means for this are discussed....

[The REACH legislation: the consumer and environment protection perspective].
Gundert-Remy, Ursula
2008-12-01
REACH has been initiated with the aim of improving existing legislation. In order to assist in the interpretation of the REACH legislation, guidance documents have been developed, which have only lately become available. According to the REACH annexes and supported by guidance documents, waiving of test requirements will be possible, thus, opening the possibility that under REACH no new (eco)toxicological data will be required. Concerning products, a guidance document was released in April 2008 stating that the substance concentration threshold of 0.1 % (w/w) applies to the article as produced or imported and it does not relate to the homogeneous materials or parts of an article, but relates to the article as such (i.e., as produced or imported). Hence, notification will not be required for many products containing chemicals with properties which place them on the candidate list for authorization. In summary, it is at present not foreseeable whether the expected benefit of the REACH legislation will materialise for the environment and for the health of consumers and at the work place.

Robot-assisted training is a widely used technique to promote motor re-learning on post-stroke patients that suffer from motor impairment. While it is commonly accepted that robot-based therapies are potentially helpful, strong insights about their efficacy are still lacking. The motor re-learning process may act on muscular synergies, which are groups of co-activating muscles that, being controlled as a synergic group, allow simplifying the problem of motor control. In fact, by coordinating a reduced amount of neural signals, complex motor patterns can be elicited. This paper aims at analyzing the effects of robot assistance during 3D-reaching movements in the framework of muscular synergies. 5 healthy people and 3 neurological patients performed free and robot-assisted reaching movements at 2 different speeds (slow and quasi-physiological). EMG recordings were used to extract muscular synergies. Results indicate that the interaction with the robot very slightly alters healthy people patterns but, on the contrary, it may promote the emergency of physiological-like synergies on neurological patients.

Full Text Available Technology has penetrated in all human activities in a positive way, but there are many questions about the impact on society due to the significant time devoted to it, especially by young people. Activities such as reading, homework or self-education are relegated by others linked to virtual communication and entertainment. The research underlying this article, undertaken in Quito, Ecuador, has established that young people between 12 and 18 years old spend on average 7h50 per day using the television, computer, video game consoles, music players, mobile phones and landlines. The intensive use of these devices shows that the behavior of young people and the strategies to reach them have changed. It is necessary to understand this new reality.

PURPOSE: Shift workers are exposed to more physical and psychosocial stressors in the working environment as compared to day workers. Despite the need for targeted prevention, it is likely that workplace interventions less frequently reach shift workers. The aim was therefore to investigate whether...... the reach of workplace interventions varied between shift workers and day workers and whether such differences could be explained by the quality of leadership exhibited at different times of the day. METHODS: We used questionnaire data from 5361 female care workers in the Danish eldercare sector...

In response to the growing numbers of young people affected by HIV around the world, MTV (Music TV), the world's largest television network, has aired a global HIV prevention campaign since 1999, expanding it into a multicomponent campaign in 2002. Questions have been raised, however, about whether MTV is an appropriate channel for these messages, given its provocative content and its reach to those at the upper end of the socioeconomic scale. To address questions about who MTV reaches, viewership data were analyzed from baseline surveys conducted as part of an evaluation of the 2002 HIV prevention campaign. The two sites included in this analysis were Kathmandu, Nepal, and São Paulo, Brazil-each with very different cultures and media environments. We found that, in general, heavier viewers of MTV are younger, better educated, and more dependent on their parents, and they have more access to satellite television and the Internet. MTV viewing was associated with positive attitudes toward HIV prevention behaviors (except for abstinence until marriage) but not with premarital sexual activity.

Memory-guided reaching in a patient with visual hemiagnosia.
Cornelsen, Sonja; Rennig, Johannes; Himmelbach, Marc
2016-06-01
The two-visual-systems hypothesis (TVSH) postulates that memory-guided movements rely on intact functions of the ventral stream. Its particular importance for memory-guided actions was initially inferred from behavioral dissociations in the well-known patient DF. Despite of rather accurate reaching and grasping movements to visible targets, she demonstrated grossly impaired memory-guided grasping as much as impaired memory-guided reaching. These dissociations were later complemented by apparently reversed dissociations in patients with dorsal damage and optic ataxia. However, grasping studies in DF and optic ataxia patients differed with respect to the retinotopic position of target objects, questioning the interpretation of the respective findings as a double dissociation. In contrast, the findings for reaching errors in both types of patients came from similar peripheral target presentations. However, new data on brain structural changes and visuomotor deficits in DF also questioned the validity of a double dissociation in reaching. A severe visuospatial short-term memory deficit in DF further questioned the specificity of her memory-guided reaching deficit. Therefore, we compared movement accuracy in visually-guided and memory-guided reaching in a new patient who suffered a confined unilateral damage to the ventral visual system due to stroke. Our results indeed support previous descriptions of memory-guided movements' inaccuracies in DF. Furthermore, our data suggest that recently discovered optic-ataxia like misreaching in DF is most likely caused by her parieto-occipital and not by her ventral stream damage. Finally, multiple visuospatial memory measurements in HWS suggest that inaccuracies in memory-guided reaching tasks in patients with ventral damage cannot be explained by visuospatial short-term memory or perceptual deficits, but by a specific deficit in visuomotor processing.

Full Text Available Anders Johan W Andersen,1 Tommy Svensson21Department of Psychosocial Health, University of Agder, Grimstad, Norway; 2Department of Behavioural Sciences and Learning, Linköping University, Linköping, SwedenAbstract: The Internet has enlarged the scope of human communication, opening new avenues for connecting with people who are struggling with their lives. This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services’ answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples’ messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity.Keywords: depression, e-mental health, health psychology, Internet, public health

2015-01-01
New challenges for regulators are emerging about a specific assessment and appropriate management of the potential risks of nanomaterials. In the framework of European legislation on chemicals, Regulation (EC) No. 1907/2006 REACH aims to ensure the safety of human health and the environment through the collection of information on the physico-chemical characteristics of the substances and on their profile (eco) toxicological and the identification of appropriate risk management linked to 'exposure to these substances without impeding scientific progress and the competitiveness of industry. In order to cover the current shortage of information on the safety of nanomaterials and tackle the acknowledged legal vacuum, are being a rich activities, carried out both by regulators both by stake holders, and discussions on the proposals for adapting the European regulatory framework for chemicals . The European Commission is geared to strengthen the REACH Regulation by means of updates of its annexes. The importance of responding to the regulatory requirements has highlighted the need for cooperation between European organizations, scientists and industries to promote and ensure the safe use of nanomaterials.

Shulman, Caroline; Low, Joseph; Hewett, Nigel; Daley, Julian; Davis, Sarah; Brophy, Nimah; Howard, Diana; Vivat, Bella; Kennedy, Peter; Stone, Patrick
2017-01-01
Objectives To explore the views and experiences of people who are homeless and those supporting them regarding conversations and approaches to palliative care Setting Data were collected between October 2015 and October 2016 in homeless hostels and day centres and with staff from primary and secondary healthcare providers and social care services from three London boroughs. Participants People experiencing homelessness (n=28), formerly homeless people (n=10), health and social care providers (n=48), hostel staff (n=30) and outreach staff (n=10). Methods In this qualitative descriptive study, participants were recruited to interviews and focus groups across three London boroughs. Views and experiences of end-of-life care were explored with people with personal experience of homelessness, health and social care professionals and hostel and outreach staff. Saturation was reached when no new themes emerged from discussions. Results 28 focus groups and 10 individual interviews were conducted. Participants highlighted that conversations exploring future care preferences and palliative care with people experiencing homelessness are rare. Themes identified as challenges to such conversations included attitudes to death; the recovery focused nature of services for people experiencing homelessness; uncertainty regarding prognosis and place of care; and fear of negative impact. Conclusions This research highlights the need for a different approach to supporting people who are homeless and are experiencing advanced ill health, one that incorporates uncertainty and promotes well-being, dignity and choice. We propose parallel planning and mapping as a way of working with uncertainty. We acknowledge that these approaches will not always be straightforward, nor will they be suitable for everyone, yet moving the focus of conversations about the future away from death and dying, towards the present and the future may facilitate conversations and enable the wishes of people who are

Lee, Jihyun; Pizzol, Massimo; Thomsen, Marianne
In recent years, the paradigm of chemical management system has changed from being toxicity oriented and media based to being risk oriented and receptor based. This trend is evident not only regarding environmental quality standards, but also for industrial chemical regulations. Political...... instruments to support a precautionary chemicals management system and to protect receptor’s health have also been increasing. Since 2007, the European Union adopted REACH (the Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals): REACH makes industry responsible for assessing...... and managing the risks posed by industrial chemicals and providing appropriate safety information to their users (EC, 2007). However, to ensure a high level of protection of human health and the environment, there is a need to consider ‘aggregate exposure’ including background exposures from environment which...

The organizers of the 2014 US National Climate Assessment (NCA) made a concerted effort to reach out to and collaborate with Indigenous peoples, resulting in the most comprehensive information to date on climate change impacts to Indigenous peoples in a US national assessment. Yet, there is still much room for improvement in assessment processes to ensure adequate recognition of Indigenous perspectives and Indigenous knowledge systems. This article discusses the process used in creating the Indigenous Peoples, Land, and Resources NCA chapter by a team comprised of tribal members, agencies, academics, and non-governmental organizations, who worked together to solicit, collect, and synthesize traditional knowledges and data from a diverse array of Indigenous communities across the US. It also discusses the synergy and discord between traditional knowledge systems and science and the emergence of cross-cutting issues and vulnerabilities for Indigenous peoples. The challenges of coalescing information about climate change and its impacts on Indigenous communities are outlined along with recommendations on the types of information to include in future assessment outputs. We recommend that future assessments – not only NCA, but other relevant local, regional, national, and international efforts aimed at the translation of climate information and assessments into meaningful actions – should support integration of Indigenous perspectives in a sustained way that builds respectful relationships and effectively engages Indigenous communities. Given the large number of tribes in the US and the current challenges and unique vulnerabilities of Indigenous communities, a special report focusing solely on climate change and Indigenous peoples is warranted.This article is part of a special issue on “The National Climate Assessment: Innovations in Science and Engagement” edited by Katharine Jacobs, Susanne Moser, and James Buizer.

Continuation and maintenance treatments for depression in older people.
Wilkinson, Philip; Izmeth, Zehanah
2016-09-09
Depressive illness is common in old age. Prevalence in the community of case level depression is around 15% and milder forms of depression are more common. It causes significant distress and disability. The number of people over the age of 60 years is expected to double by 2050 and so interventions for this often long-term and recurrent condition are increasingly important. The causes of late-life depression differ from depression in younger adults and so it is appropriate to study it separately.This is an update of a Cochrane review first published in 2012. To examine the efficacy of antidepressants and psychological therapies in preventing the relapse and recurrence of depression in older people. We performed a search of the Cochrane Common Mental Disorders Group's specialised register (the CCMDCTR) to 13 July 2015. The CCMDCTR includes relevant randomised controlled trials (RCTs) from the following bibliographic databases: The Cochrane Library (all years), MEDLINE (1950 to date), EMBASE (1974 to date), and PsycINFO (1967 to date). We also conducted a cited reference search on 13 July 2015 of the Web of Science for citations of primary reports of included studies. Both review authors independently selected studies. We included RCTs involving people aged 60 years and over successfully treated for an episode of depression and randomised to receive continuation and maintenance treatment with antidepressants, psychological therapies, or a combination. Two review authors independently extracted data. The primary outcome for benefit was recurrence rate of depression (reaching a cut-off on any depression rating scale) at 12 months and the primary outcome for harm was drop-outs at 12 months. Secondary outcomes included relapse/recurrence rates at other time points, global impression of change, social functioning, and deaths. We performed meta-analysis using risk ratio (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, with 95% confidence

2016-05-27
Cost-effective and efficient methods to attract people to Web-based health behavior interventions need to be identified. Traditional print methods including leaflets, posters, and newspaper advertisements remain popular despite the expanding range of Web-based advertising options that have the potential to reach larger numbers at lower cost. This study evaluated the effectiveness of multiple Web-based and print-based methods to attract people to a Web-based physical activity intervention. A range of print-based (newspaper advertisements, newspaper articles, letterboxing, leaflets, and posters) and Web-based (Facebook advertisements, Google AdWords, and community calendars) methods were applied to attract participants to a Web-based physical activity intervention in Australia. The time investment, cost, number of first time website visits, the number of completed sign-up questionnaires, and the demographics of participants were recorded for each advertising method. A total of 278 people signed up to participate in the physical activity program. Of the print-based methods, newspaper advertisements totaled AUD $145, letterboxing AUD $135, leaflets AUD $66, posters AUD $52, and newspaper article AUD $3 per sign-up. Of the Web-based methods, Google AdWords totaled AUD $495, non-targeted Facebook advertisements AUD $68, targeted Facebook advertisements AUD $42, and community calendars AUD $12 per sign-up. Although the newspaper article and community calendars cost the least per sign-up, they resulted in only 17 and 6 sign-ups respectively. The targeted Facebook advertisements were the next most cost-effective method and reached a large number of sign-ups (n=184). The newspaper article and the targeted Facebook advertisements required the lowest time investment per sign-up (5 and 7 minutes respectively). People reached through the targeted Facebook advertisements were on average older (60 years vs 50 years, Padvertising is the most cost-effective and efficient method at

Full Text Available To evaluate the equilibrium and flexibility of elderly people submitted to a training program involving physical therapy exercises. Six elderly people were selected, average age 69.66 years. Wells’s Bench and the Functional Reach Test (FRT plus Timed Up and Go Test (TUG were employed respectively to assess muscle flexibility and balance analysis. Tests were performed before and after the exercise program which consisted of thirty-five 50 min physical therapy group sessions, twice a week, with stretching exercises, gait training, active exercises, postural correction exercises and breathing exercises. Statistical analysis was done with Sigma-Stat® 3.5. Assessments occurred before and after sessions, and the final test was undertaken after 35 sessions. There was a statistically significant increase in the flexibility of the posterior muscle chain. In the TUG test, the group achieved a shorter time after treatment, with statistical significance between tests. There was a statistically significant increase in the average FRT after the sessions. Current study showed better results in the execution of tests evaluated after the program of physiotherapy activities, contributing towards the improvement of muscle flexibility and balance of elderly people.

Management of children and young people with headache.
Whitehouse, William P; Agrawal, Shakti
2017-04-01
Headache is very common in children and young people. The correct advice and treatment requires consideration of a wide differential diagnosis between primary and secondary headaches, and also of the different types of primary headache. The International Classification of Headache Disorders gives useful descriptions and diagnostic criteria that are especially useful for primary headaches. The National Institute for Health and Care Excellence (NICE) Clinical Guideline 150 provides evidence-based recommendations on treatments for adults and young people from age 12 years. However, the same principles can be applied to younger children when a specific diagnosis can be made. Key recommendations from the NICE Quality Standards include, establishing a precise diagnosis if possible, avoiding, diagnosing and treating medication overuse headache, and combining a triptan with a non-steroidal anti-inflammatory drug or paracetamol as the first-line acute/rescue treatment for migraine with or without aura. Although rare in children and young people, it is important to diagnose new daily persistent headache, as it responds poorly or not at all to medication; and paroxysmal hemicrania as it responds very well to indomethacin but not to other commonly used analgesics. When faced with difficulties in reaching a precise diagnosis or in finding effective therapies, further advice should be sought from a children's headache clinic or specialist.

Proprioceptive body illusions modulate the visual perception of reaching distance.
Directory of Open Access Journals (Sweden)
Agustin Petroni
Full Text Available The neurobiology of reaching has been extensively studied in human and non-human primates. However, the mechanisms that allow a subject to decide-without engaging in explicit action-whether an object is reachable are not fully understood. Some studies conclude that decisions near the reach limit depend on motor simulations of the reaching movement. Others have shown that the body schema plays a role in explicit and implicit distance estimation, especially after motor practice with a tool. In this study we evaluate the causal role of multisensory body representations in the perception of reachable space. We reasoned that if body schema is used to estimate reach, an illusion of the finger size induced by proprioceptive stimulation should propagate to the perception of reaching distances. To test this hypothesis we induced a proprioceptive illusion of extension or shrinkage of the right index finger while participants judged a series of LEDs as reachable or non-reachable without actual movement. Our results show that reach distance estimation depends on the illusory perceived size of the finger: illusory elongation produced a shift of reaching distance away from the body whereas illusory shrinkage produced the opposite effect. Combining these results with previous findings, we suggest that deciding if a target is reachable requires an integration of body inputs in high order multisensory parietal areas that engage in movement simulations through connections with frontal premotor areas.

Sampling in the absence of accurate or comprehensive information routinely poses logistical, ethical, and resource allocation challenges in social science, clinical, epidemiological, health service and population health research. These challenges are compounded if few members of a target population know each other or regularly interact. This paper reports on the sampling methods adopted in ethnographic case study research with a 'hard-to-reach' population. To identify and engage a small yet diverse sample of people who met an unusual set of criteria (i.e., pet owners who had been treating cats or dogs for diabetes), four sampling strategies were used. First, copies of a recruitment letter were posted in pet-friendly places. Second, information about the study was diffused throughout the study period via word of mouth. Third, the lead investigator personally sent the recruitment letter via email to a pet owner, who then circulated the information to others, and so on. Fourth, veterinarians were enlisted to refer people who had diabetic pets. The second, third and fourth strategies rely on social networks and represent forms of chain referral sampling. Chain referral sampling via email proved to be the most efficient and effective, yielding a small yet diverse group of respondents within one month, and at negligible cost. The widespread popularity of electronic communication technologies offers new methodological opportunities for researchers seeking to recruit from hard-to-reach populations.

Tuberculosis is over-represented in hard-to-reach (underserved) populations in high-income countries of low tuberculosis incidence. The mainstay of tuberculosis care is early detection of active tuberculosis (case finding), contact tracing, and treatment completion. We did a systematic review with a scoping component of relevant studies published between 1990 and 2015 to update and extend previous National Institute for Health and Care Excellence (NICE) reviews on the effectiveness of interventions for identifying and managing tuberculosis in hard-to-reach populations. The analyses showed that tuberculosis screening by (mobile) chest radiography improved screening coverage and tuberculosis identification, reduced diagnostic delay, and was cost-effective among several hard-to-reach populations. Sputum culture for pre-migration screening and active referral to a tuberculosis clinic improved identification. Furthermore, monetary incentives improved tuberculosis identification and management among drug users and homeless people. Enhanced case management, good cooperation between services, and directly observed therapy improved treatment outcome and compliance. Strong conclusions cannot be drawn because of the heterogeneity of evidence with regard to study population, methodology, and quality. Copyright © 2017 Elsevier Ltd. All rights reserved.

Rahola, T.; Suomela, M.; Illukka, E.; Pusa, S.
1991-03-01
After the reactor accident at Chernobyl radioactive fallout was carried by air streams to most parts of Europe. In 1988 radionuclides causing internal contamination were transported to man only via foodchains and no longer via inhalation, as had happened immediately after the Chernobyl accident. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the Chemobyl accident, whole-body counting measurements were performed. Nine different groups of people were measured during 1988. Three were local reference groups, two groups of radiation workers, one a population group representing the whole country and three groups representing those with special dietary habits. The weighted mean 137 Cs body burden in the population group was 1300 Bq at the end of 1988, the minimum body burden being 50 Bq and the maximum 7700 Bq. The measurement data showed that the maximum body burdens were reached in summer 1987. The group with special diets did not necessarily follow this pattern. The mean effective dose equivalents delivered to people in Finland in 1988, estimated by using the measurement data on the population goup, was 0.05 mSv the corresponding dose equivalent in 1987 being 0.08 mSv

Falling off the bandwagon? Exploring the challenges to sustained digital engagement by older people.
Damodaran, L; Olphert, C W; Sandhu, J
2014-01-01
This study examines older people's use of information and communication technologies (ICTs) and identifies the factors which can prevent or promote their sustained use. A mixed methods approach was adopted. Quantitative and qualitative data were collected by a survey of 323 older ICT users (aged ≥50 years) between 2011 and 2012. These data were supplemented by qualitative data obtained through in-depth interviews, focus groups and storytelling. Quantitative data were analysed using PASW including bivariate and multivariate analyses. Qualitative data were analysed using an inductive, thematic approach. The findings show that, contrary to some stereotypes, many older people are enthusiastic, competent and confident users of ICTs. However, they report a range of challenges in reaching and maintaining this situation. These include technological complexity and change, age-related capability changes and a lack of learning and support mechanisms. Intrinsic motivation and social support are important in enabling older people to overcome these challenges. Getting older people online has been a high priority in many countries over the past decade. However, little attention has been paid to whether and how their usage can be sustained over time. We discuss the implications of the findings for policy and practice.

Environmental stressors afflicting tailwater stream reaches across the United States
Miranda, Leandro E.; Krogman, R. M.
2014-01-01
The tailwater is the reach of a stream immediately below an impoundment that is hydrologically, physicochemically and biologically altered by the presence and operation of a dam. The overall goal of this study was to gain a nationwide awareness of the issues afflicting tailwater reaches in the United States. Specific objectives included the following: (i) estimate the percentage of reservoirs that support tailwater reaches with environmental conditions suitable for fish assemblages throughout the year, (ii) identify and quantify major sources of environmental stress in those tailwaters that do support fish assemblages and (iii) identify environmental features of tailwater reaches that determine prevalence of key fish taxa. Data were collected through an online survey of fishery managers. Relative to objective 1, 42% of the 1306 reservoirs included in this study had tailwater reaches with sufficient flow to support a fish assemblage throughout the year. The surface area of the reservoir and catchment most strongly delineated reservoirs maintaining tailwater reaches with or without sufficient flow to support a fish assemblage throughout the year. Relative to objective 2, major sources of environmental stress generally reflected flow variables, followed by water quality variables. Relative to objective 3, zoogeography was the primary factor discriminating fish taxa in tailwaters, followed by a wide range of flow and water quality variables. Results for objectives 1–3 varied greatly among nine geographic regions distributed throughout the continental United States. Our results provide a large-scale view of the effects of reservoirs on tailwater reaches and may help guide research and management needs.

Do People Really Want Freedom of Choice? Assessing preferences of pension participants
van Dalen, H.P.; Henkens, K.
2017-01-01
Reforms in private pension plans across the world are opening up more options for pension participants to make choices to suit their preferences. Freedom of choice is however not a unidimensional concept as it is commonly perceived by policy makers. People can value both the freedom to choose as well as the freedom not to choose This observation can have far-reaching implications for pension policy design. By using a unique panel survey among Dutch employees we are able to offer a more refine...

Ricardo Esteban Legarreta
2014-06-01
Full Text Available This paper is aimed at a critical analysis of the main tools existing in Spain to foster the employment of people with disabilities in the open labour market considering the new Consolidated Text of the General Act on the Rights of People with Disabilities and its social inclusion (Royal Legislative Decree 1/2013 and the Global Strategy on Employment of People with Disabilities 2008-2012. The main incentives are reductions in Social Security contributions and financial bonuses. The paper’s methodology is based in the study of both the law and the case law. Firstly, with regard to the reductions in Social Security contributions, the paper evaluates its reach, the different types of employment contracts concerned and the circumstances which could hamper employers’ access to bonuses. Secondly, the article evaluates some key issues regarding employment grants like their amount, the specific concept of disabled person to be hired or the possibility to pile up national and autonomous (regional grants. Finally, the article evaluates the existing limited grant to carry out workplace adjustments.

The Cognition of Maximal Reach Distance in Parkinson’s Disease
Directory of Open Access Journals (Sweden)
Satoru Otsuki
2016-01-01
Full Text Available This study aimed to investigate whether the cognition of spatial distance in reaching movements was decreased in patients with Parkinson’s disease (PD and whether this cognition was associated with various symptoms of PD. Estimated and actual maximal reaching distances were measured in three directions in PD patients and healthy elderly volunteers. Differences between estimated and actual measurements were compared within each group. In the PD patients, the associations between “error in cognition” of reaching distance and “clinical findings” were also examined. The results showed that no differences were observed in any values regardless of dominance of hand and severity of symptoms. The differences between the estimated and actual measurements were negatively deviated in the PD patients, indicating that they tended to underestimate reaching distance. “Error in cognition” of reaching distance correlated with the items of posture in the motor section of the Unified Parkinson’s Disease Rating Scale. This suggests that, in PD patients, postural deviation and postural instability might affect the cognition of the distance from a target object.

Diagnostic Accuracy of Fall Risk Assessment Tools in People With Diabetic Peripheral Neuropathy
Pohl, Patricia S.; Mahnken, Jonathan D.; Kluding, Patricia M.
2012-01-01
Background Diabetic peripheral neuropathy affects nearly half of individuals with diabetes and leads to increased fall risk. Evidence addressing fall risk assessment for these individuals is lacking. Objective The purpose of this study was to identify which of 4 functional mobility fall risk assessment tools best discriminates, in people with diabetic peripheral neuropathy, between recurrent “fallers” and those who are not recurrent fallers. Design A cross-sectional study was conducted. Setting The study was conducted in a medical research university setting. Participants The participants were a convenience sample of 36 individuals between 40 and 65 years of age with diabetic peripheral neuropathy. Measurements Fall history was assessed retrospectively and was the criterion standard. Fall risk was assessed using the Functional Reach Test, the Timed “Up & Go” Test, the Berg Balance Scale, and the Dynamic Gait Index. Sensitivity, specificity, positive and negative likelihood ratios, and overall diagnostic accuracy were calculated for each fall risk assessment tool. Receiver operating characteristic curves were used to estimate modified cutoff scores for each fall risk assessment tool; indexes then were recalculated. Results Ten of the 36 participants were classified as recurrent fallers. When traditional cutoff scores were used, the Dynamic Gait Index and Functional Reach Test demonstrated the highest sensitivity at only 30%; the Dynamic Gait Index also demonstrated the highest overall diagnostic accuracy. When modified cutoff scores were used, all tools demonstrated improved sensitivity (80% or 90%). Overall diagnostic accuracy improved for all tests except the Functional Reach Test; the Timed “Up & Go” Test demonstrated the highest diagnostic accuracy at 88.9%. Limitations The small sample size and retrospective fall history assessment were limitations of the study. Conclusions Modified cutoff scores improved diagnostic accuracy for 3 of 4 fall risk

Key Design Requirements for Long-Reach Manipulators
Energy Technology Data Exchange (ETDEWEB)
Kwon, D.S.
2001-01-01
Long-reach manipulators differ from industrial robots and teleoperators typically used in the nuclear industry in that the aspect ratio (length to diameter) of links is much greater and link flexibility, as well as joint or drive train flexibility, is likely to be significant. Long-reach manipulators will be required for a variety of applications in the Environmental Restoration and Waste Management Program. While each application will present specific functional, kinematic, and performance requirements, an approach for determining the kinematic applicability and performance characteristics is presented, with a focus on waste storage tank remediation. Requirements are identified, kinematic configurations are considered, and a parametric study of link design parameters and their effects on performance characteristics is presented.

Dynamic channel adjustments in the Jingjiang Reach of the Middle Yangtze River
Xia, Junqiang; Deng, Shanshan; Lu, Jinyou; Xu, Quanxi; Zong, Quanli; Tan, Guangming
2016-03-01
Significant channel adjustments have occurred in the Jingjiang Reach of the Middle Yangtze River, because of the operation of the Three Gorges Project (TGP). The Jingjiang Reach is selected as the study area, covering the Upper Jingjiang Reach (UJR) and Lower Jingjiang Reach (LJR). The reach-scale bankfull channel dimensions in the study reach were calculated annually from 2002 to 2013 by means of a reach-averaged approach and surveyed post-flood profiles at 171 sections. We find from the calculated results that: the reach-scale bankfull widths changed slightly in the UJR and LJR, with the corresponding depths increasing by 1.6 m and 1.0 m the channel adjustments occurred mainly with respect to bankfull depth because of the construction of large-scale bank revetment works, although there were significant bank erosion processes in local regions without the bank protection engineering. The reach-scale bankfull dimensions in the UJR and LJR generally responded to the previous five-year average fluvial erosion intensity during flood seasons, with higher correlations being obtained for the depth and cross-sectional area. It is concluded that these dynamic adjustments of the channel geometry are a direct result of recent human activities such as the TGP operation.

Differential Recruitment of Parietal Cortex during Spatial and Non-spatial Reach Planning
Directory of Open Access Journals (Sweden)
Pierre-Michel Bernier
2017-05-01
Full Text Available The planning of goal-directed arm reaching movements is associated with activity in the dorsal parieto-frontal cortex, within which multiple regions subserve the integration of arm- and target-related sensory signals to encode a motor goal. Surprisingly, many of these regions show sustained activity during reach preparation even when target location is not specified, i.e., when a motor goal cannot be unambiguously formed. The functional role of these non-spatial preparatory signals remains unresolved. Here this process was investigated in humans by comparing reach preparatory activity in the presence or absence of information regarding upcoming target location. In order to isolate the processes specific to reaching and to control for visuospatial attentional factors, the reaching task was contrasted to a finger movement task. Functional MRI and electroencephalography (EEG were used to characterize the spatio-temporal pattern of reach-related activity in the parieto-frontal cortex. Reach planning with advance knowledge of target location induced robust blood oxygenated level dependent and EEG responses across parietal and premotor regions contralateral to the reaching arm. In contrast, reach preparation without knowledge of target location was associated with a significant BOLD response bilaterally in the parietal cortex. Furthermore, EEG alpha- and beta-band activity was restricted to parietal scalp sites, the magnitude of the latter being correlated with reach reaction times. These results suggest an intermediate stage of sensorimotor transformations in bilateral parietal cortex when target location is not specified.

Efficacy of REACH Forgiveness across cultures.
Lin, Yin; Worthington, Everett L; Griffin, Brandon J; Greer, Chelsea L; Opare-Henaku, Annabella; Lavelock, Caroline R; Hook, Joshua N; Ho, Man Yee; Muller, Holly
2014-09-01
This study investigates the efficacy of the 6-hour REACH Forgiveness intervention among culturally diverse undergraduates. Female undergraduates (N = 102) and foreign extraction (46.2%) and domestic (43.8%) students in the United States were randomly assigned to immediate treatment or waitlist conditions. Treatment efficacy and the effect of culture on treatment response were assessed using measures of emotional and decisional forgiveness across 3 time periods. Students in the treatment condition reported greater improvement in emotional forgiveness, but not decisional forgiveness, relative to those in the waitlist condition. Gains were maintained at a 1-week follow-up. Although culture did not moderate the effect of treatment, a main effect of culture on emotional forgiveness and marginally significant interaction effect of culture on decisional forgiveness were found. The REACH Forgiveness intervention was efficacious for college students from different cultural backgrounds when conducted in the United States. However, some evidence may warrant development of culturally adapted forgiveness interventions. © 2014 Wiley Periodicals, Inc.

BROOKHAVEN: Proton goal reached

1995-01-01
On March 30 the 35-year old Alternating Gradient Synchrotron (AGS) exceeded its updated design goal of 6 x 10 13 protons per pulse (ppp), by accelerating 6.3 x 10 13 ppp, a world record intensity. This goal was set 11 years ago and achieving it called for the construction of a new booster and the reconstruction of much of the AGS. The booster was completed in 1991, and reached its design intensity of 1.5 x 10 13 ppp in 1993. The AGS reconstruction was finished in 1994, and by July of that year the AGS claimed a new US record intensity for a proton synchrotron of 4 x 10 13 ppp, using four booster pulses. Reaching the design intensity was scheduled for 1995. In 1994, the AGS had seemed to be solidly limited to 4 x 10 13 ppp, but in 1995 the operations crew, working on their own in the quiet of the owl shift, steadily improved the intensity, regularly setting new records, much to the bemusement of the machine physicists. The physicists, however, did contribute. A second harmonic radiofrequency cavity in the booster increased the radiofrequency bucket area for capture, raising the booster intensity from 1.7 to 2.1 x 10 13 ppp. In the AGS, new radiofrequency power supplies raised the available voltage from 8 to 13 kV, greatly enhancing the beam loading capabilities of the system. A powerful new transverse damping system successfully controlled instabilities that otherwise would have destroyed the beam in less than a millisecond. Also in the AGS, 35th harmonic octupole resonances were found

To explore the views and experiences of people who are homeless and those supporting them regarding conversations and approaches to palliative care SETTING: Data were collected between October 2015 and October 2016 in homeless hostels and day centres and with staff from primary and secondary healthcare providers and social care services from three London boroughs. People experiencing homelessness (n=28), formerly homeless people (n=10), health and social care providers (n=48), hostel staff (n=30) and outreach staff (n=10 ). METHODS: In this qualitative descriptive study, participants were recruited to interviews and focus groups across three London boroughs. Views and experiences of end-of-life care were explored with people with personal experience of homelessness, health and social care professionals and hostel and outreach staff. Saturation was reached when no new themes emerged from discussions. 28 focus groups and 10 individual interviews were conducted. Participants highlighted that conversations exploring future care preferences and palliative care with people experiencing homelessness are rare. Themes identified as challenges to such conversations included attitudes to death; the recovery focused nature of services for people experiencing homelessness; uncertainty regarding prognosis and place of care; and fear of negative impact. This research highlights the need for a different approach to supporting people who are homeless and are experiencing advanced ill health, one that incorporates uncertainty and promotes well-being, dignity and choice. We propose parallel planning and mapping as a way of working with uncertainty. We acknowledge that these approaches will not always be straightforward, nor will they be suitable for everyone, yet moving the focus of conversations about the future away from death and dying, towards the present and the future may facilitate conversations and enable the wishes of people who are homeless to be known and explored.

Channel morphodynamics in four reaches of the Lower Missouri River, 2006-07
Elliott, Caroline M.; Reuter, Joanna M.; Jacobson, Robert B.
2009-01-01
Channel morphodynamics in response to flow modifications from Gavins Point Dam are examined in four reaches of the Lower Missouri River. Measures include changes in channel morphology and indicators of sediment transport in four 6 kilometer long reaches located downstream from Gavins Point Dam, near Yankton, South Dakota, Kenslers Bend, Nebraska, Little Sioux, Iowa, and Miami, Missouri. Each of the four reaches was divided into 300 transects with a 20-meter spacing and surveyed during the summer in 2006 and 2007. A subset of 30 transects was randomly selected and surveyed 7-10 times in 2006-07 over a wide range of discharges including managed and natural flow events. Hydroacoustic mapping used a survey-grade echosounder and a Real Time Kinematic Global Positioning System to evaluate channel change. Acoustic Doppler current profiler measurements were used to evaluate bed-sediment velocity. Results indicate varying amounts of deposition, erosion, net change, and sediment transport in the four Lower Missouri River reaches. The Yankton reach was the most stable over monthly and annual time-frames. The Kenslers Bend and Little Sioux reaches exhibited substantial amounts of deposition and erosion, although net change was generally low in both reaches. Total, or gross geomorphic change was greatest in the Kenslers Bend reach. The Miami reach exhibited varying rates of deposition and erosion, and low net change. The Yankton, Kenslers Bend, and Miami reaches experienced net erosion during the time period that bracketed the managed May 2006 spring rise event from Gavins Point Dam.

Whisker and Nose Tactile Sense Guide Rat Behavior in a Skilled Reaching Task
Directory of Open Access Journals (Sweden)
Pierantonio Parmiani
2018-02-01
Full Text Available Skilled reaching is a complex movement in which a forelimb is extended to grasp food for eating. Video-recordings analysis of control rats enables us to distinguish several components of skilled reaching: Orient, approaching the front wall of the reaching box and poking the nose into the slot to locate the food pellet; Transport, advancing the forelimb through the slot to reach-grasp the pellet; and Withdrawal of the grasped food to eat. Although food location and skilled reaching is guided by olfaction, the importance of whisker/nose tactile sense in rats suggests that this too could play a role in reaching behavior. To test this hypothesis, we studied skilled reaching in rats trained in a single-pellet reaching task before and after bilateral whisker trimming and bilateral infraorbital nerve (ION severing. During the task, bilaterally trimmed rats showed impaired Orient with respect to controls. Specifically, they detected the presence of the wall by hitting it with their nose (rather than their whiskers, and then located the slot through repetitive nose touches. The number of nose touches preceding poking was significantly higher in comparison to controls. On the other hand, macrovibrissae trimming resulted in no change in reaching/grasping or withdrawal components of skilled reaching. Bilaterally ION-severed rats, displayed a marked change in the structure of their skilled reaching. With respect to controls, in ION-severed rats: (a approaches to the front wall were significantly reduced at 3–5 and 6–8 days; (b nose pokes were significantly reduced at 3–5 days, and the slot was only located after many repetitive nose touches; (c the reaching-grasping-retracting movement never appeared at 3–5 days; (d explorative paw movements, equal to zero in controls, reached significance at 9–11 days; and (e the restored reaching-grasping-retracting sequence was globally slower than in controls, but the success rate was the same. These findings

How infants' reaches reveal principles of sensorimotor decision making
Dineva, Evelina; Schöner, Gregor
2018-01-01
In Piaget's classical A-not-B-task, infants repeatedly make a sensorimotor decision to reach to one of two cued targets. Perseverative errors are induced by switching the cue from A to B, while spontaneous errors are unsolicited reaches to B when only A is cued. We argue that theoretical accounts of sensorimotor decision-making fail to address how motor decisions leave a memory trace that may impact future sensorimotor decisions. Instead, in extant neural models, perseveration is caused solely by the history of stimulation. We present a neural dynamic model of sensorimotor decision-making within the framework of Dynamic Field Theory, in which a dynamic instability amplifies fluctuations in neural activation into macroscopic, stable neural activation states that leave memory traces. The model predicts perseveration, but also a tendency to repeat spontaneous errors. To test the account, we pool data from several A-not-B experiments. A conditional probabilities analysis accounts quantitatively how motor decisions depend on the history of reaching. The results provide evidence for the interdependence among subsequent reaching decisions that is explained by the model, showing that by amplifying small differences in activation and affecting learning, decisions have consequences beyond the individual behavioural act.

Amplified Erosion above Waterfalls and Oversteepened Bedrock Reaches
Haviv, I.; Enzel, Y.; Whipple, K. X.; Zilberman, E.; Stone, J.; Matmon, A.; Fifield, K. L.
2005-12-01
Although waterfalls are abundant along steep bedrock channels, none of the conventional erosion laws can predict incision at the lip of a waterfall where flow is non-uniform and bed slope can be vertical. Considering the expected increase in flow velocity and shear stress at the lip of a vertical waterfall we determine erosion amplification at a waterfall lip as: Elip/Enormal= (1+0.4/Fr2)3n, where Fr is the Froude number and n ranges between 0.5-1.7. This amplification expression suggests that erosion at the lip could be as much as 2-5 times higher than normally expected in a setting with identical hydraulic geometry. It also demonstrates that a freefall is expected to amplify upstream incision rates even when the flow approaching the waterfall is highly supercritical. Utilizing this erosion amplification expression in numerical simulations in conjunction with a standard detachment-limited incision model we demonstrate its impact on reach-scale morphology above waterfalls. These simulations indicate that amplified erosion at the lip of a waterfall can trigger the formation of an oversteepened reach whose length is longer than the flow acceleration zone, provided incision velocity (Vi) at the edge of the flow acceleration zone is higher than the retreat velocity of the waterfall face. Such an oversteepened reach is expected to be more pronounced when Vi increases with increasing slope. The simulations also suggest that oversteepening can eventually lead to quasi steady-state gradients upstream from a waterfall provided Vi decreases with increasing slope. Flow acceleration above waterfalls can thus account, at least partially, for oversteepened bedrock reaches that are prevalent above waterfalls. Such reaches have been reported for the escarpments of southeast Australia, western Dead Sea, and at Niagara Falls. Using the cosmogenic isotope 36Cl we demonstrate that Vi upstream of a waterfall at the Dead Sea western escarpment is high enough for freefall

Adaptation of reach-to-grasp movement in response to force perturbations.
Rand, M K; Shimansky, Y; Stelmach, G E; Bloedel, J R
2004-01-01
This study examined how reach-to-grasp movements are modified during adaptation to external force perturbations applied on the arm during reach. Specifically, we examined whether the organization of these movements was dependent upon the condition under which the perturbation was applied. In response to an auditory signal, all subjects were asked to reach for a vertical dowel, grasp it between the index finger and thumb, and lift it a short distance off the table. The subjects were instructed to do the task as fast as possible. The perturbation was an elastic load acting on the wrist at an angle of 105 deg lateral to the reaching direction. The condition was modified by changing the predictability with which the perturbation was applied in a given trial. After recording unperturbed control trials, perturbations were applied first on successive trials (predictable perturbations) and then were applied randomly (unpredictable perturbations). In the early predictable perturbation trials, reach path length became longer and reaching duration increased. As more predictable perturbations were applied, the reach path length gradually decreased and became similar to that of control trials. Reaching duration also decreased gradually as the subjects adapted by exerting force against the perturbation. In addition, the amplitude of peak grip aperture during arm transport initially increased in response to repeated perturbations. During the course of learning, it reached its maximum and thereafter slightly decreased. However, it did not return to the normal level. The subjects also adapted to the unpredictable perturbations through changes in both arm transport and grasping components, indicating that they can compensate even when the occurrence of the perturbation cannot be predicted during the inter-trial interval. Throughout random perturbation trials, large grip aperture values were observed, suggesting that a conservative aperture level is set regardless of whether the

Full Text Available Abstract Background Sampling in the absence of accurate or comprehensive information routinely poses logistical, ethical, and resource allocation challenges in social science, clinical, epidemiological, health service and population health research. These challenges are compounded if few members of a target population know each other or regularly interact. This paper reports on the sampling methods adopted in ethnographic case study research with a 'hard-to-reach' population. Methods To identify and engage a small yet diverse sample of people who met an unusual set of criteria (i.e., pet owners who had been treating cats or dogs for diabetes, four sampling strategies were used. First, copies of a recruitment letter were posted in pet-friendly places. Second, information about the study was diffused throughout the study period via word of mouth. Third, the lead investigator personally sent the recruitment letter via email to a pet owner, who then circulated the information to others, and so on. Fourth, veterinarians were enlisted to refer people who had diabetic pets. The second, third and fourth strategies rely on social networks and represent forms of chain referral sampling. Results Chain referral sampling via email proved to be the most efficient and effective, yielding a small yet diverse group of respondents within one month, and at negligible cost. Conclusions The widespread popularity of electronic communication technologies offers new methodological opportunities for researchers seeking to recruit from hard-to-reach populations.

Bringing Terra Science to the People: 10 years of education and public outreach
Riebeek, H.; Chambers, L. H.; Yuen, K.; Herring, D.
2009-12-01
The default image on Apple's iPhone is a blue, white, green and tan globe: the Blue Marble. The iconic image was produced using Terra data as part of the mission's education and public outreach efforts. As far-reaching and innovative as Terra science has been over the past decade, Terra education and public outreach efforts have been equally successful. This talk will provide an overview of Terra's crosscutting education and public outreach projects, which have reached into educational facilities—classrooms, museums, and science centers, across the Internet, and into everyday life. The Earth Observatory web site was the first web site designed for the public that told the unified story of what we can learn about our planet from all space-based platforms. Initially conceived as part of Terra mission outreach in 1999, the web site has won five Webby awards, the highest recognition a web site can receive. The Visible Earth image gallery is a catalogue of NASA Earth imagery that receives more than one million page views per month. The NEO (NASA Earth Observations) web site and WMS (web mapping service) tool serves global data sets to museums and science centers across the world. Terra educational products, including the My NASA Data web service and the Students' Cloud Observations Online (S'COOL) project, bring Terra data into the classroom. Both projects target multiple grade levels, ranging from elementary school to graduate school. S'COOL uses student observations of clouds to help validate Terra data. Students and their parents have puzzled over weekly "Where on Earth" geography quizzes published on line. Perhaps the most difficult group to reach is the large segment of the public that does not seek out science information online or in a science museum or classroom. To reach these people, EarthSky produced a series of podcasts and radio broadcasts that brought Terra science to more than 30 million people in 2009. Terra imagery, including the Blue Marble, have

An Evaluation of Web- and Print-Based Methods to Attract People to a Physical Activity Intervention
Jennings, Cally; Plotnikoff, Ronald C; Vandelanotte, Corneel
2016-01-01
Background Cost-effective and efficient methods to attract people to Web-based health behavior interventions need to be identified. Traditional print methods including leaflets, posters, and newspaper advertisements remain popular despite the expanding range of Web-based advertising options that have the potential to reach larger numbers at lower cost. Objective This study evaluated the effectiveness of multiple Web-based and print-based methods to attract people to a Web-based physical activity intervention. Methods A range of print-based (newspaper advertisements, newspaper articles, letterboxing, leaflets, and posters) and Web-based (Facebook advertisements, Google AdWords, and community calendars) methods were applied to attract participants to a Web-based physical activity intervention in Australia. The time investment, cost, number of first time website visits, the number of completed sign-up questionnaires, and the demographics of participants were recorded for each advertising method. Results A total of 278 people signed up to participate in the physical activity program. Of the print-based methods, newspaper advertisements totaled AUD $145, letterboxing AUD $135, leaflets AUD $66, posters AUD $52, and newspaper article AUD $3 per sign-up. Of the Web-based methods, Google AdWords totaled AUD $495, non-targeted Facebook advertisements AUD $68, targeted Facebook advertisements AUD $42, and community calendars AUD $12 per sign-up. Although the newspaper article and community calendars cost the least per sign-up, they resulted in only 17 and 6 sign-ups respectively. The targeted Facebook advertisements were the next most cost-effective method and reached a large number of sign-ups (n=184). The newspaper article and the targeted Facebook advertisements required the lowest time investment per sign-up (5 and 7 minutes respectively). People reached through the targeted Facebook advertisements were on average older (60 years vs 50 years, PFacebook advertising is the

The wavelength division multiplexing-time division multiplexing (WDM-TDM) passive optical network (PON) using reflective semiconductor optical amplifier (RSOA)-based colorless optical networking units (ONUs) is considered as a promising candidate for the realization of fiber-to-the-home (FTTH). And this architecture is actively considered by Industrial Technology Research Institute (ITRI) for the realization of FTTH in Taiwan. However, different fiber distances and optical components would introduce different power budgets to different ONUs in the PON. Besides, due to the aging of optical transmitter (Tx), the power decay of the distributed optical carrier from the central office (CO) could also reduce the injection power into each ONU. The situation will be more severe in the long-reach (LR) PON, which is considered as an option for the future access. In this work, we investigate a WDM-TDM PON using RSOA-based ONU for upstream data rate adjustment depending on different continuous wave (CW) injection powers. Both standard-reach (25 km) and LR (100 km) transmissions are evaluated. Moreover, a detail analysis of the upstream signal bit-error rate (BER) performances at different injection powers, upstream data rates, PON split-ratios under stand-reach and long-reach is presented.

Full Text Available Background. HIV-infected women are disproportionately burdened by gynaecological complications, psychological disorders, and certain sexually transmitted infections that may not be adequately addressed by HIV-specific care. We estimate the prevalence and covariates of women’s health care (WHC utilization among harder-to-reach, treatment-experienced HIV-infected women in British Columbia (BC, Canada. Methods. We used survey data from 231 HIV-infected, treatment-experienced women enrolled in the Longitudinal Investigations into Supportive and Ancillary Health Services (LISA study, which recruited harder-to-reach populations, including aboriginal people and individuals using injection drugs. Independent covariates of interest included sociodemographic, psychosocial, behavioural, individual health status, structural factors, and HIV clinical variables. Logistic regression was used to generate adjusted estimates of associations between use of WHC and covariates of interest. Results. Overall, 77% of women reported regularly utilizing WHC. WHC utilization varied significantly by region of residence (P value <0.01. In addition, women with lower annual income (AOR (95% CI = 0.14 (0.04–0.54, who used illicit drugs (AOR (95% CI = 0.42 (0.19–0.92 and who had lower provider trust (AOR (95% CI = 0.97 (0.95–0.99, were significantly less likely to report using WHC. Conclusion. A health service gap exists along geographical and social axes for harder-to-reach HIV-infected women in BC. Women-centered WHC and HIV-specific care should be streamlined and integrated to better address women’s holistic health.

People and Places Forum Workshop Report | Science ...
In November 2015, the Twin Ports-based People and Places Work Group (PPWG) coordinated a special gathering to bring together researchers and scholars from diverse fields to discuss environment-human research, scholarship and collaboration opportunities. Hosted by the US Environmental Protection Agency (USEPA), the group approached and invited over 150 individuals from eight regional universities. The goals were to learn who was doing or interested in doing applied research on human-environment interactions, who might have students to engage in work, who might partner with the Lake Superior National Estuarine Research Reserve (Reserve), USEPA, University of Minnesota Duluth’s Natural Resource Research Institute (NRRI), Minnesota and Wisconsin Sea Grant Institutes (Sea Grant), and other partnering institutes and who might be interested in ecosystem services work in particular. A pre-gathering survey collected initial information about this community and the adapted, open-space design gathering allowed for even more data collection about potential new colleagues to engage in the work of understanding people and place in our region. This summary reviews some of findings and presents what may be considered the beginning of a network directory to encourage and facilitate interdisciplinary research and collaboration. This report outlines the process to identify and reach out to health, social science, and humanities scholars to participate in environmental research w

Rahola, T.; Suomela, M.; Illukka, E.; Pusa, S.
1989-08-01
The atmospheric nuclear bomb tests in the 1950s, '60s and '70s caused global radioactive fallout. After the reactor accident at Chernobyl on April 26, 1986, radioactive fallout was carried by by air streams to most parts of Europe. In 1987 radionuclides causing internal contamination were transported to man only via different foodchains and no longer via inhalation, as had happened immediately after the Chernobyl accident. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the Chernobyl accident, whole-body counting measurements were performed. Ten different groups of people were measured during 1987. Three were local reference groups, two groups of radiation workers, one a population group representing the whole country and four groups representing those with special dietary habits. The weighted mean 137 Cs body burden in the population group was 2000 Bq at the end of 1987, the minimum body burden being 200 Bq and the maximum 10000 Bq. The measurement results showed that the maximum body burdens were reached in the summer 1987. The groups with special diets did not necessarily follow this pattern. The mean effective dose equivalents delivered in 1987 to people in Finland, estimated by using the measurement results of the population group, was 0.08 mSv, the corresponding dose equivalent in 1986 bein 0.06 mSv

Full Text Available When a major flooding event is expected the authorities in charge of the crisis management often consider bringing people to safety by making them leaving temporarily the threatened area before the onset of the flood. This strategy is called “horizontal evacuation”. It has to be distinguished from “vertical evacuation”, which means that people reach a shelter above the wtaer level within the flood area. Vertical evacuation is often the spontaneousbehaviourof people who are surprised by the flood and are trying to reach a tree, a floor upstairs, a roof of a building etc. in order to get away from the rising water. But vertical evacuation could also be consideredas an alternative strategy to horizontal evacuation when moving outside the flood area is neither a faisible nor a relevant option, for example in high-population density areas. In order to be a credible alternative to horizontal evacuation, vertical evacuation has to be carefully planned. This paper aims to explain why horizontal evacuation is not always a suitable option in case of major flood and to explore under what conditions vertical evacuation can be a relevantalternative solution to horizontal evacuation. It also adresses some general recommendations about how to prepare a vertical evacuation strategy..

Olefins and chemical regulation in Europe: REACH.
Penman, Mike; Banton, Marcy; Erler, Steffen; Moore, Nigel; Semmler, Klaus
2015-11-05
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is the European Union's chemical regulation for the management of risk to human health and the environment (European Chemicals Agency, 2006). This regulation entered into force in June 2007 and required manufacturers and importers to register substances produced in annual quantities of 1000 tonnes or more by December 2010, with further deadlines for lower tonnages in 2013 and 2018. Depending on the type of registration, required information included the substance's identification, the hazards of the substance, the potential exposure arising from the manufacture or import, the identified uses of the substance, and the operational conditions and risk management measures applied or recommended to downstream users. Among the content developed to support this information were Derived No-Effect Levels or Derived Minimal Effect Levels (DNELs/DMELs) for human health hazard assessment, Predicted No Effect Concentrations (PNECs) for environmental hazard assessment, and exposure scenarios for exposure and risk assessment. Once registered, substances may undergo evaluation by the European Chemicals Agency (ECHA) or Member State authorities and be subject to requests for additional information or testing as well as additional risk reduction measures. To manage the REACH registration and related activities for the European olefins and aromatics industry, the Lower Olefins and Aromatics REACH Consortium was formed in 2008 with administrative and technical support provided by Penman Consulting. A total of 135 substances are managed by this group including 26 individual chemical registrations (e.g. benzene, 1,3-butadiene) and 13 categories consisting of 5-26 substances. This presentation will describe the content of selected registrations prepared for 2010 in addition to the significant post-2010 activities. Beyond REACH, content of the registrations may also be relevant to other European activities, for

Employment, career advancement, and financial independence are highly valued in the United States. As expectations, they are often instilled at a young age and incentivized throughout adulthood. Despite their importance, employment and economic sufficiency continue to be out of reach for most people with intellectual and developmental disabilities (IDD). Over the last quarter century, extensive research and effort has been committed to understanding and improving these phenomena. This paper summarizes this employment research base by reviewing the literature on the effectiveness of the current employment support system, employment-specific interventions, and the economics and cost benefits of employment for people with IDD. Recommendations and directions for future research are also presented.

Taking Research and Knowledge to the Common People
Hossain, F.
2017-12-01
Most sponsored research in this world is driven by the need to improve livelihood and the environment around us. This is particularly true for the case of earth and environmental issues involving the resources of water, food, energy and health. However, is such research guaranteed of bringing positive benefits for society as soon as it is documented in peer-reviewed forums or in media publications? More than 2 decades ago the United States National Research Council popularized the term "Valley of Death" to describe the region where research findings struggle to survive before reaching maturity for societal applications. Recent experience in the field of earth and environmental sciences shows that many of the potential beneficiaries (i.e., the common people), who are not as familiar with the motivation behind sponsored research in the field, may have a more skeptical view based on their current and archaic practices in their livelihood. This talk will shed light this "Valley of Death" for research and ways to accelerate the societal impact of research to the common people. Using examples drawing from technology, water, food and physical modeling of earth, this talk will also share lessons learned on ways to be effective agents of change for making a direct impact with scientific research.

Proximal and distal adjustments of reaching behavior in preterm infants.
de Toledo, Aline Martins; Soares, Daniele de Almeida; Tudella, Eloisa
2011-01-01
The authors aimed to investigate proximal and distal adjustments of reaching behavior and grasping in 5-, 6-, and 7-month-old preterm infants. Nine low-risk preterm and 10 full-term infants participated. Both groups showed the predominance of unimanual reaching, an age-related increase in the frequency of vertical-oriented and open hand movement, and also an increase in successful grasping from 6 to 7 months. The frequency of open hand was higher in the preterm group at 6 months. Intrinsic restrictions imposed by prematurity did not seem to have impaired reaching performance of preterm infants throughout the months of age.

Effect of tonic pain on motor acquisition and retention while learning to reach in a force field.
Lamothe, Mélanie; Roy, Jean-Sébastien; Bouffard, Jason; Gagné, Martin; Bouyer, Laurent J; Mercier, Catherine
2014-01-01
Most patients receiving intensive rehabilitation to improve their upper limb function experience pain. Despite this, the impact of pain on the ability to learn a specific motor task is still unknown. The aim of this study was to determine whether the presence of experimental tonic pain interferes with the acquisition and retention stages of motor learning associated with training in a reaching task. Twenty-nine healthy subjects were randomized to either a Control or Pain Group (receiving topical capsaicin cream on the upper arm during training on Day 1). On two consecutive days, subjects made ballistic movements towards two targets (NEAR/FAR) using a robotized exoskeleton. On Day 1, the task was performed without (baseline) and with a force field (adaptation). The adaptation task was repeated on Day 2. Task performance was assessed using index distance from the target at the end of the reaching movement. Motor planning was assessed using initial angle of deviation of index trajectory from a straight line to the target. Results show that tonic pain did not affect baseline reaching. Both groups improved task performance across time (pControl group for the FAR target (p = 0.030) during both acquisition and retention. Moreover, a Group x Time interaction (p = 0.028) was observed on initial angle of deviation, suggesting that subjects with Pain made larger adjustments in the feedforward component of the movement over time. Interestingly, behaviour of the Pain group was very stable from the end of Day 1 (with pain) to the beginning of Day 2 (pain-free), indicating that the differences observed could not solely be explained by the impact of pain on immediate performance. This suggests that if people learn to move differently in the presence of pain, they might maintain this altered strategy over time.

Access to primary health care services for Indigenous peoples: A framework synthesis.
Davy, Carol; Harfield, Stephen; McArthur, Alexa; Munn, Zachary; Brown, Alex
2016-09-30
Indigenous peoples often find it difficult to access appropriate mainstream primary health care services. Securing access to primary health care services requires more than just services that are situated within easy reach. Ensuring the accessibility of health care for Indigenous peoples who are often faced with a vast array of additional barriers including experiences of discrimination and racism, can be complex. This framework synthesis aimed to identify issues that hindered Indigenous peoples from accessing primary health care and then explore how, if at all, these were addressed by Indigenous health care services. To be included in this framework synthesis papers must have presented findings focused on access to (factors relating to Indigenous peoples, their families and their communities) or accessibility of Indigenous primary health care services. Findings were imported into NVivo and a framework analysis undertaken whereby findings were coded to and then thematically analysed using Levesque and colleague's accessibility framework. Issues relating to the cultural and social determinants of health such as unemployment and low levels of education influenced whether Indigenous patients, their families and communities were able to access health care. Indigenous health care services addressed these issues in a number of ways including the provision of transport to and from appointments, a reduction in health care costs for people on low incomes and close consultation with, if not the direct involvement of, community members in identifying and then addressing health care needs. Indigenous health care services appear to be best placed to overcome both the social and cultural determinants of health which hamper Indigenous peoples from accessing health care. Findings of this synthesis also suggest that Levesque and colleague's accessibility framework should be broadened to include factors related to the health care system such as funding.

Call to action: A new path for improving diabetes care for Indigenous peoples, a global review.
Harris, Stewart B; Tompkins, Jordan W; TeHiwi, Braden
2017-01-01
Diabetes has reached epidemic proportions in Indigenous populations around the globe, and there is an urgent need to improve the health and health equity of Indigenous peoples with diabetes through timely and appropriate diabetes prevention and management strategies. This review describes the evolution of the diabetes epidemic in Indigenous populations and associated risk factors, highlighting gestational diabetes and intergenerational risk, lifestyle risk factors and social determinants as having particular importance and impact on Indigenous peoples. This review further describes the impact of chronic disease and diabetes on Indigenous peoples and communities, specifically diabetes-related comorbidities and complications. This review provides continued evidence that dramatic changes are necessary to reduce diabetes-related inequities in Indigenous populations, with a call to action to support programmatic primary healthcare transformation capable of empowering Indigenous peoples and communities and improving chronic disease prevention and management. Promising strategies for transforming health services and care for Indigenous peoples include quality improvement initiatives, facilitating diabetes and chronic disease registry and surveillance systems to identify care gaps, and prioritizing evaluation to build the evidence-base necessary to guide future health policy and planning locally and on a global scale.

Mobile Phones and Psychosocial Therapies with Vulnerable People: a First State of the Art.
Vázquez, Maria Yolanda García; Sexto, Carlos Ferrás; Rocha, Álvaro; Aguilera, Adrián
2016-06-01
Mobile phones are becoming a communication tool commonly used by people all over the world; and they are started to be adopted in psychosocial therapies involving vulnerable people. We are herein presenting the results of an academic literature review. We identified scientific papers published between 2006 and 2015 resorting to academic databases available on the Internet, applying a systematic selection method based on quality criteria. Secondly, we analysed contents, highlighting the scarcity of research involving vulnerable people. The available literature specialized in psychosocial therapies offers investigation results which involve mobile phones and patients in general, focusing particularly on the clinical psychology field and, to a lesser extent, on the social work field. Particularly significant are the investigation works developed in the United States. In the present paper we introduce a first "state of the art", identifying opportunities and also the limitations surrounding the use of mobile phones in psychosocial therapies targeting the vulnerable. Issues concerning privacy and data confidentiality, and the access of vulnerable people to mobile phones and how they use them, pose significant challenges; but they offer the opportunity to reach isolated or impoverished populations, or even to facilitate access to social and healthcare services. We close this paper formulating possible orientations, hypotheses and goals to design new investigation works involving vulnerable populations.

As a part of the Department of Energy's Environmental Restoration and Waste Management Program, long-reach manipulators are being considered for the retrieval of waste from large storage tanks. Long-reach manipulators may have characteristics significantly different from those of typical industrial robots because of the flexibility of long links needed to cover the large workspace. To avoid structural vibrations during operation, control algorithms employing various types of shaping filters were investigated. A new approach that uses embedded simulation was developed and compared with others. In the new approach, generation of joint trajectories considering link flexibility was also investigated

Young Idea People Mix with Old Idea People to Make the World Better
Hall, M.
2017-12-01
Groups of young idea people come to eat, drink, and talk about new ideas that old idea people are working on to change the world for the better. The ideas may fix our body and mind, make our lives easier or harder, and more. The young idea people lead, learn, listen and act, so they can become old idea people. The young idea people scare the old idea people because their ideas are different. And, sometimes, the young idea people have new ideas that the old idea people have not thought about. When this happens it makes the old idea people happy and better at their work. The old idea people get to go places and share their ideas around the world. They make good money and have fun lives. They write about their work and can be well known, or not. The young idea people learn from the old idea people how they can be like them. Together the young and old idea people build things and talk about crazy ideas that may come to be. Sometimes the old idea people talk too much and don't listen. They use big words that can be hard to understand. But, the young idea people help them learn to use known words so everyone learns. We know the young idea people learn and grow from this act and they grow happier about their life. We also know that the old idea people get happy that the young idea people are so bright.

Reach-to-grasp movement as a minimization process.
Yang, Fang; Feldman, Anatol G
2010-02-01
It is known that hand transport and grasping are functionally different but spatially coordinated components of reach-to-grasp (RTG) movements. As an extension of this notion, we suggested that body segments involved in RTG movements are controlled as a coherent ensemble by a global minimization process associated with the necessity for the hand to reach the motor goal. Different RTG components emerge following this process without pre-programming. Specifically, the minimization process may result from the tendency of neuromuscular elements to diminish the spatial gap between the actual arm-hand configuration and its virtual (referent) configuration specified by the brain. The referent configuration is specified depending on the object shape, localization, and orientation. Since the minimization process is gradual, it can be interrupted and resumed following mechanical perturbations, at any phase during RTG movements, including hand closure. To test this prediction of the minimization hypothesis, we asked subjects to reach and grasp a cube placed within the reach of the arm. Vision was prevented during movement until the hand returned to its initial position. As predicted, by arresting wrist motion at different points of hand transport in randomly selected trials, it was possible to halt changes in hand aperture at any phase, not only during hand opening but also during hand closure. Aperture changes resumed soon after the wrist was released. Another test of the minimization hypothesis was made in RTG movements to an object placed beyond the reach of the arm. It has previously been shown (Rossi et al. in J Physiol 538:659-671, 2002) that in such movements, the trunk motion begins to contribute to hand transport only after a critical phase when the shifts in the referent arm configuration have finished (at about the time when hand velocity is maximal). The minimization rule suggests that when the virtual contribution of the arm to hand transport is completed

Leadership in moving human groups.
Directory of Open Access Journals (Sweden)
Margarete Boos
2014-04-01
Full Text Available How is movement of individuals coordinated as a group? This is a fundamental question of social behaviour, encompassing phenomena such as bird flocking, fish schooling, and the innumerable activities in human groups that require people to synchronise their actions. We have developed an experimental paradigm, the HoneyComb computer-based multi-client game, to empirically investigate human movement coordination and leadership. Using economic games as a model, we set monetary incentives to motivate players on a virtual playfield to reach goals via players' movements. We asked whether (I humans coordinate their movements when information is limited to an individual group member's observation of adjacent group member motion, (II whether an informed group minority can lead an uninformed group majority to the minority's goal, and if so, (III how this minority exerts its influence. We showed that in a human group--on the basis of movement alone--a minority can successfully lead a majority. Minorities lead successfully when (a their members choose similar initial steps towards their goal field and (b they are among the first in the whole group to make a move. Using our approach, we empirically demonstrate that the rules of swarming behaviour apply to humans. Even complex human behaviour, such as leadership and directed group movement, follow simple rules that are based on visual perception of local movement.

Do children perceive postural constraints when estimating reach or action planning?
Gabbard, Carl; Cordova, Alberto; Lee, Sunghan
2009-03-01
Estimation of whether an object is reachable from a specific body position constitutes an important aspect in effective motor planning. Researchers who estimate reachability by way of motor imagery with adults consistently report the tendency to overestimate, with some evidence of a postural effect (postural stability hypothesis). This idea suggests that perceived reaching limits depend on an individual's perceived postural constraints. Based on previous work with adults, the authors expected a significant postural effect with the Reach 2 condition, as evidenced by reduced overestimation. Furthermore, the authors hypothesized that the postural effect would be greater in younger children. They then tested these propositions among children aged 7, 9, and 11 years by asking them to estimate reach while seated (Reach 1) and in the more demanding posture of standing on 1 foot and leaning forward (Reach 2). Results indicated no age or condition difference, therefore providing no support for a postural effect. When the authors compared these data to a published report of adults, a developmental difference emerged. That is, adults recognize the perceived postural constraint of the standing position resulting in under- rather than overestimation, as displayed in the seated condition. Although preliminary, these observations suggest that estimates of reach (action planning) continue to be refined between late childhood and young adulthood.

2004-01-01
Exploring the influence of the Internet on the lives of indigenous and diasporic peoples, Kyra Landzelius leads a team of expert anthropologists and ethnographers who go on-site and on-line to explore how a diverse range of indigenous and transnational diasporic communities actually use the Internet. From the Taino Indians of the Caribbean, the U'wa of the Amazon rainforest, and the Tunomans and Assyrians of Iraq, to the Tingas and Zapatistas, Native on the Net is a lively and intriguing exploration of how new technologies have enabled these previously isolated peoples to reach new levels of communication and community: creating new communities online, confronting global corporations, or even challenging their own native traditions. Featuring case studies ranging from the Artic to the Australian outback, this book addresses important recurrent themes, such as the relationship between identity and place, community, traditional cultures and the nature of the 'indigenous'. Native on the Net is a unique contribut...

Locations of serial reach targets are coded in multiple reference frames.
Thompson, Aidan A; Henriques, Denise Y P
2010-12-01
Previous work from our lab, and elsewhere, has demonstrated that remembered target locations are stored and updated in an eye-fixed reference frame. That is, reach errors systematically vary as a function of gaze direction relative to a remembered target location, not only when the target is viewed in the periphery (Bock, 1986, known as the retinal magnification effect), but also when the target has been foveated, and the eyes subsequently move after the target has disappeared but prior to reaching (e.g., Henriques, Klier, Smith, Lowy, & Crawford, 1998; Sorrento & Henriques, 2008; Thompson & Henriques, 2008). These gaze-dependent errors, following intervening eye movements, cannot be explained by representations whose frame is fixed to the head, body or even the world. However, it is unknown whether targets presented sequentially would all be coded relative to gaze (i.e., egocentrically/absolutely), or if they would be coded relative to the previous target (i.e., allocentrically/relatively). It might be expected that the reaching movements to two targets separated by 5° would differ by that distance. But, if gaze were to shift between the first and second reaches, would the movement amplitude between the targets differ? If the target locations are coded allocentrically (i.e., the location of the second target coded relative to the first) then the movement amplitude should be about 5°. But, if the second target is coded egocentrically (i.e., relative to current gaze direction), then the reaches to this target and the distances between the subsequent movements should vary systematically with gaze as described above. We found that requiring an intervening saccade to the opposite side of 2 briefly presented targets between reaches to them resulted in a pattern of reaching error that systematically varied as a function of the distance between current gaze and target, and led to a systematic change in the distance between the sequential reach endpoints as predicted by

Robot-mediated therapy (RMT) has been a very dynamic area of research in recent years. Robotics devices are in fact capable to quantify the performances of a rehabilitation task in treatments of several disorders of the arm and the shoulder of various central and peripheral etiology. Different systems for robot-aided neuro-rehabilitation are available for upper limb rehabilitation but the biomechanical parameters proposed until today, to evaluate the quality of the movement, are related to the specific robot used and to the type of exercise performed. Besides, none study indicated a standardized quantitative evaluation of robot assisted upper arm reaching movements, so the RMT is still far to be considered a standardised tool. In this paper a quantitative kinematic assessment of robot assisted upper arm reaching movements, considering also the effect of gravity on the quality of the movements, is proposed. We studied a group of 10 healthy subjects and results indicate that our advised protocol can be useful for characterising normal pattern in reaching movements.

Artarxerxes Tiago Tácito Modesto
2012-02-01
Full Text Available The emergence of the Internet has caused a revolution with regard to new forms of interaction between people, offering experiences of real-time communication in so-called virtual environments. Given this scenario, new textual genres emerge, making room for innumerous possibilities of analysis under various approaches. In this paper, we aim at analyzing digital conversations, trying to verify, at first, the extent to which they approach or move away from face-to-face conversations. We also seek to identify, describe and analyze some interactional strategies inherent in this new genre. We base our analyzes on Conversation Analysis theory and Interactional Sociolinguistics to define conversational strategies of the “spoken written text” on the Internet. The corpus used in this work consists of digital conversations coming from the MSN instant messaging software from Microsoft Corporation, chosen because of its wide use among people who use the internet for communication.

Use of Social Media During Public Emergencies by People with Disabilities
Directory of Open Access Journals (Sweden)
John T. Morris
2014-08-01
Full Text Available Introduction: People with disabilities are generally more vulnerable during disasters and public emergencies than the general population. Physical, sensory and cognitive impairments may result in greater difficulty in receiving and understanding emergency alert information, and greater difficulty in taking appropriate action. The use of social media in the United States has grown considerably in recent years. This has generated increasing interest on the part of national, state and local jurisdictions in leveraging these channels to communicate public health and safety information. How and to what extent people with disabilities use social and other communications media during public emergencies can help public safety organizations understand the communication needs of the citizens in their jurisdictions, and plan their social media and other communications strategies accordingly. Methods: This article presents data from a survey on the use of social media and other communications media during public emergencies by people with disabilities conducted from November 1, 2012 through March 30, 2013. Results: The data presented here show four key results. First, levels of use of social media in general are high for people with disabilities, as well as for the general population. Second, use of social media during emergencies is still low for both groups. Third, levels of use of social media are not associated with income levels, but are significantly and strongly associated with age: younger people use social media at higher rates than older people in both groups (p,0.001. Fourth, differences in the use of social media during emergencies across disability types are slight, with the exception of deaf and hard-of-hearing respondents, the former more likely to have used social media to receive (p¼0.002, verify (p¼0.092 and share (p¼0.007 emergency information . Conclusion: These last two results suggest that effective emergency communications

[Purpose] An earlier study divided reaching activity into characteristic phases based on hand velocity profiles. By synchronizing muscle activities and the acceleration profile, a phasing approach for reaching movement, based on hand acceleration profiles, was attempted in order to elucidate the roles of individual muscle activities in the different phases of the acceleration profile in reaching movements. [Subjects and Methods] Ten healthy volunteer subjects participated in this study. The aim was to electromyographically evaluate muscles around the shoulder, the upper trapezius, the anterior deltoid, the biceps brachii, and the triceps brachii, most of which have been used to evaluate arm motion, as well as the acceleration of the upper limb during simple reaching movement in the reach-to-grasp task. [Results] Analysis showed the kinematic trajectories of the acceleration during a simple biphasic profile of the reaching movement could be divided into four phases: increasing acceleration (IA), decreasing acceleration (DA), increasing deceleration (ID), and decreasing deceleration (DD). Muscles around the shoulder showed different activity patterns, which were closely associated with these acceleration phases. [Conclusion] These results suggest the important role of the four phases, derived from the acceleration trajectory, in the elucidation of the muscular mechanisms which regulate and coordinate the muscles around the shoulder in reaching movements.

Full Text Available An aging population is associated with an increased prevalence of diabetes, cardiovascular diseases and depression. Important aspects of programmes targeted at older people are: to reach those at risk, effective screening, optimising advice, and referral to local interventions. We examined the effect of a preventive health consultation (PRIMUS, a multi-behavioural screening programme for persons aged 55–74 years in primary care. In a multi-centre randomised controlled trial, the effects of participating in the PRIMUS intervention were compared to a comparison group receiving personalised summaries and advice by postal mail, both preceded by a health risk assessment via a questionnaire. The intervention consisted of a baseline health risk assessment, followed by a preventive health consultation (after 4 weeks, and a follow-up visit (2 weeks later in the primary care centre. A newly developed web-based computer-tailored programme supported the nurse practitioner during the consultation. Main outcomes measures were awareness of, and compliance with referral advice for changing unhealthy lifestyles. The PRIMUS preventive health consultation was successful in older people at risk for cardio metabolic diseases compared to the comparison group (compliance: RR 1.43; 95% CI 1.12–1.79; p < 0.05. The intervention was less successful in older people at risk for mental health problems. This preventive health consultation for older people resulted in positive changes in unhealthy behaviours by optimising reach, raising awareness, motivating and assisting individuals to change, and referring to local interventions.

Full Text Available For the past few decades, the Eastern Mediterranean Region has been one area of the world profoundly shaped by war and political instability. On-going conflict and destruction have left the region struggling with innumerable health concerns that have claimed the lives of many. Wars, and the chaos they leave behind, often provide the optimal conditions for the growth and re-emergence of communicable diseases. In this article, we highlight a few of the major re-emerging vaccine preventable diseases in four countries of the Eastern Mediterranean Region that are currently affected by war leading to a migration crisis: Iraq, South Sudan, Syria, and Yemen. We will also describe the impact these infections have had on patients, societies, and national health care services. This article also describes the efforts, both local and international, which have been made to address these crises, as well as future endeavors that can be done to contain and control further devastation left by these diseases.

Decoding Grasping Movements from the Parieto-Frontal Reaching Circuit in the Nonhuman Primate.
Nelissen, Koen; Fiave, Prosper Agbesi; Vanduffel, Wim
2018-04-01
Prehension movements typically include a reaching phase, guiding the hand toward the object, and a grip phase, shaping the hand around it. The dominant view posits that these components rely upon largely independent parieto-frontal circuits: a dorso-medial circuit involved in reaching and a dorso-lateral circuit involved in grasping. However, mounting evidence suggests a more complex arrangement, with dorso-medial areas contributing to both reaching and grasping. To investigate the role of the dorso-medial reaching circuit in grasping, we trained monkeys to reach-and-grasp different objects in the dark and determined if hand configurations could be decoded from functional magnetic resonance imaging (MRI) responses obtained from the reaching and grasping circuits. Indicative of their established role in grasping, object-specific grasp decoding was found in anterior intraparietal (AIP) area, inferior parietal lobule area PFG and ventral premotor region F5 of the lateral grasping circuit, and primary motor cortex. Importantly, the medial reaching circuit also conveyed robust grasp-specific information, as evidenced by significant decoding in parietal reach regions (particular V6A) and dorsal premotor region F2. These data support the proposed role of dorso-medial "reach" regions in controlling aspects of grasping and demonstrate the value of complementing univariate with more sensitive multivariate analyses of functional MRI (fMRI) data in uncovering information coding in the brain.

Enhancing early engagement with mental health services by young people

Full Text Available Jane Burns, Emma Birrell Young and Well Cooperative Research Centre, Abbotsford, VIC, Australia Abstract: International studies have shown that the prevalence of mental illness, and the fundamental contribution it make to the overall disease burden, is greatest in children and young people. Despite this high burden, adolescents and young adults are the least likely population group to seek help or to access professional care for mental health problems. This issue is particularly problematic given that untreated, or poorly treated, mental disorders are associated with both short- and long-term functional impairment, including poorer education and employment opportunities, potential comorbidity, including drug and alcohol problems, and a greater risk for antisocial behavior, including violence and aggression. This cycle of poor mental health creates a significant burden for the young person, their family and friends, and society as a whole. Australia is enviably positioned to substantially enhance the well-being of young people, to improve their engagement with mental health services, and – ultimately – to improve mental health. High prevalence but potentially debilitating disorders, such as depression and anxiety, are targeted by the specialized youth mental health service, headspace: the National Youth Mental Health Foundation and a series of Early Psychosis Prevention and Intervention Centres, will provide early intervention specialist services for low prevalence, complex illnesses. Online services, such as ReachOut.com by Inspire Foundation, Youthbeyondblue, Kids Helpline, and Lifeline Australia, and evidence-based online interventions, such as MoodGYM, are also freely available, yet a major challenge still exists in ensuring that young people receive effective evidence-based care at the right time. This article describes Australian innovation in shaping a comprehensive youth mental health system, which is informed by an evidence

People with mental illnesses face stigma that hinders their full integration into society. Work is a major determinant of social inclusion, however, people with mental disorders have fewer opportunities to work. Emerging evidence suggests that social enterprises help disadvantaged people with their work integration process. The purpose of this study is to enhance our understanding about how perceptions of stigma can be decreased for people with mental disorders throughout their work experience in a social enterprise. Using a longitudinal study design, 310 individuals with mental disorders employed in Italian social enterprises completed a battery of questionnaires on individual (e.g., severity of symptoms; occupational self-efficacy) and environmental (e.g., social support; organizational constraints) variables. Of the 223 individuals potentially eligible at the 12-month follow up, 139 completed a battery of questionnaires on social and working skills, perceived work productivity and perceived stigma. Path analyses were used to test a model delineating how people with mental disorders working in social enterprises improve social and work outcomes (i.e., motivation, skills and productivity), and reduce the perception of being stigmatized. Working in a social enterprise enhances working social skills, which leads to a perception of higher productivity and, consequently, the perception of being discriminated against and stigmatized is reduced. Social enterprise provides a context in which people with mental disorders reach a sense of work-related and social competence. This sense of competence helps them to reduce perceived stigma, which is a crucial step toward social inclusion. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

International reach of tobacco marketing among young children.
Borzekowski, Dina L G; Cohen, Joanna E
2013-10-01
Prosmoking messages, delivered through marketing and the media, can reach very young children and influence attitudes and behaviors around smoking. This study examined the reach of tobacco marketing to 5 and 6 year olds in 6 low- and middle-income countries. Researchers worked one-on-one with 5 and 6 year olds in Brazil, China, India, Nigeria, Pakistan, and Russia (N = 2423). The children were asked to match logos with pictures of products, including 8 logos for cigarette brands. Analyses examined, overall and by country, whether gender, age, location, household use of tobacco, and knowledge of media characters were associated with awareness of cigarette brand logos. Additional analyses considered the relationship between cigarette brand logo awareness and intentions to smoke. Overall, 68% of 5 and 6 year olds could identify at least 1 cigarette brand logo, ranging from 50% in Russia to 86% in China. Across countries, being slightly older and having someone in the household who used tobacco, were significantly associated with greater odds of being able to identify at least 1 cigarette brand logo. The majority of young children from low- and middle-income countries are familiar with cigarette brands. This study's findings suggest that more effective measures are needed to restrict the reach of tobacco marketing.

Suicide remains a major global public health issue for young people. The reach and accessibility of online and social media-based interventions herald a unique opportunity for suicide prevention. To date, the large body of research into suicide prevention has been undertaken atheoretically. This paper provides a rationale and theoretical framework (based on the interpersonal theory of suicide), and draws on our experiences of developing and testing online and social media-based interventions. The implementation of three distinct online and social media-based intervention studies, undertaken with young people at risk of suicide, are discussed. We highlight the ways that these interventions can serve to bolster social connectedness in young people, and outline key aspects of intervention implementation and moderation. Insights regarding the implementation of these studies include careful protocol development mindful of risk and ethical issues, establishment of suitably qualified teams to oversee development and delivery of the intervention, and utilisation of key aspects of human support (i.e., moderation) to encourage longer-term intervention engagement. Online and social media-based interventions provide an opportunity to enhance feelings of connectedness in young people, a key component of the interpersonal theory of suicide. Our experience has shown that such interventions can be feasibly and safely conducted with young people at risk of suicide. Further studies, with controlled designs, are required to demonstrate intervention efficacy.

Pilot study to test effectiveness of video game on reaching performance in stroke.
Acosta, Ana Maria; Dewald, Hendrik A; Dewald, Jules P A
2011-01-01
Robotic systems currently used in upper-limb rehabilitation following stroke rely on some form of visual feedback as part of the intervention program. We evaluated the effect of a video game environment (air hockey) on reaching in stroke with various levels of arm support. We used the Arm Coordination Training 3D system to provide variable arm support and to control the hockey stick. We instructed seven subjects to reach to one of three targets covering the workspace of the impaired arm during the reaching task and to reach as far as possible while playing the video game. The results from this study showed that across subjects, support levels, and targets, the reaching distances achieved with the reaching task were greater than those covered with the video game. This held even after further restricting the mapped workspace of the arm to the area most affected by the flexion synergy (effectively forcing subjects to fight the synergy to reach the hockey puck). The results from this study highlight the importance of designing video games that include specific reaching targets in the workspace compromised by the expression of the flexion synergy. Such video games would also adapt the target location online as a subject's success rate increases.

Simulation of Columbia River Floods in the Hanford Reach
Energy Technology Data Exchange (ETDEWEB)
Waichler, Scott R.; Serkowski, John A.; Perkins, William A.; Richmond, Marshall C.
2017-01-30
Columbia River water elevations and flows in the Hanford Reach affect the environment and facilities along the shoreline, including movement of contaminants in groundwater, fish habitat, and infrastructure subject to flooding. This report describes the hydraulic simulation of hypothetical flood flows using the best available topographic and bathymetric data for the Hanford Reach and the Modular Aquatic Simulation System in 1 Dimension (MASS1) hydrodynamic model. The MASS1 model of the Hanford Reach was previously calibrated to field measurements of water surface elevations. The current model setup can be used for other studies of flow, water levels, and temperature in the Reach. The existing MASS1 channel geometry and roughness and other model configuration inputs for the Hanford Reach were used for this study, and previous calibration and validation results for the model are reprinted here for reference. The flood flows for this study were simulated by setting constant flow rates obtained from the U.S. Army Corps of Engineers (USACE) for the Columbia, Snake, and Yakima Rivers, and a constant water level at McNary Dam, and then running the model to steady state. The discharge levels simulated were all low-probability events; for example, a 100-year flood is one that would occur on average every 100 years, or put another way, in any given year there is a 1% chance that a discharge of that level or higher will occur. The simulated floods and their corresponding Columbia River discharges were 100-year (445,000 cfs), 500-year (520,000 cfs), and the USACE-defined Standard Project Flood (960,000 cfs). The resulting water levels from the steady-state floods can be viewed as “worst case” outcomes for the respective discharge levels. The MASS1 output for water surface elevations was converted to the North American Vertical Datum of 1988 and projected across the channel and land surface to enable mapping of the floodplain for each scenario. Floodplain maps show that for

Who should make the decision on the use of GPS for people with dementia?
Landau, Ruth; Auslander, Gail K; Werner, Shirli; Shoval, Noam; Heinik, Jeremia
2011-01-01
In recent years advanced technologies, such as Global Positioning Systems (GPS), allow for tracking of human spatial activity and provide the ability to intervene to manage that activity. The purpose of this study is to examine the issue of who should decide about the use of electronic tracking using GPS for people with dementia. Based on quantitative data collected from 296 participants comprising cognitively intact elderly, family caregivers of people with dementia, social workers, other professionals, and social work students, study participants were asked to rate nine different potential decision-makers to make this decision. The results show that figures inside the family, particularly the spouse or the most involved family caregiver, were perceived more important in the decision-making process than figures outside the family, whereas the person with dementia was ranked third in the order of the figures. Since the decision to use GPS for tracking raises the ethical dilemma of personal safety versus autonomy and privacy of people with dementia, the findings seem to indicate that the reluctance of professional caregivers to assist family caregivers to make this decision is experienced as frustrating. The findings imply that in order to reach a balance between the wishes and interests of both people with dementia and their family caregivers, there is a need for more active involvement of the professional caregivers to facilitate the family decision-making process.

Objective: To determine the added effects of virtual reality training on turning capacity, gait parameters and functional reach capacity of stroke patients compared to task oriented training alone. Methodology: A randomized control trial was conducted from February 2016 to July 2106 at Physical Rehabilitation Department Pakistan Railway Hospital, Rawalpindi, Pakistan. Twenty stroke patients were selected through purposive sampling. The patients were randomly assigned through sealed envelope method into two groups; Task Oriented Training (TOT) and Virtual Reality Training (VRT) Group. The standardized tools were used for assessment. The TOT was provided for 4 days per week for 6 weeks while VRT group received additional exer-gaming training during sessions. Results: Significant improvement was observed in both groups regarding reaching forward, turning 360, gait pivot turn (p a 0.01) and FRT (p a 0.001). The two groups were statistically different from each other in terms of turning capacity, reaching forward, gait pivot turn and functional reach after 6 weeks of intervention (p a 0.05) Conclusion: Addition of virtual reality training further improves the significant improvement caused by task oriented training on turning capacity, reaching forward, gait pivot turn and functional reach in stroke patients.

Dry Stream Reaches in Carbonate Terranes: Surface Indicators of Ground-Water Reservoirs
Brahana, J.V.; Hollyday, E.F.
1988-01-01
In areas where dry stream reaches occur, subsurface drainage successfully competes with surface drainage, and sheet-like dissolution openings have developed parallel to bedding creating the ground-water reservoir. Union Hollow in south-central Tennessee is the setting for a case study that illustrates the application of the dry stream reach technique. In this technique, dry stream reach identification is based on two types of readily acquired information: remotely sensed black and white infrared aerial photography; and surface reconnaissance of stream channel characteristics. Test drilling in Union Hollow subsequent to identification of the dry reach proved that a localized ground-water reservoir was present.

Background: The current study aimed to examine the psychometric properties of an attributional style measure that can be administered remotely, to people who have multiple sclerosis (MS). Methods: A total of 495 participants with MS were recruited. Participants completed the Attributional Style Questionnaire-Survey (ASQ-S) and two comparison measures of cognitive variables via postal survey on three occasions, each 12 months apart. Internal reliability, test-retest reliability and congruent validity were considered. Results: The internal reliability of the ASQ-S was good (α > 0.7). The test-retest correlations were significant, but failed to reach the 0.7 set. The congruent validity of the ASQ-S was established relative to the comparisons. Conclusions: The psychometric properties of the ASQ-S indicate that it shows promise as a tool for researchers investigating depression in people with MS and is likely sound to use clinically in this population.

2018-05-02
Quality of life of people with severe mental illness may be decrease by the high occurrence of metabolic and cardiovascular diseases. Physical fitness emerges as a modifying factor in this population through physical activity and this modification could influence in the quality of life of this population. The aim of the present study is to determine the contribution of physical fitness to the quality of life of people with severe mental illness. In the current study, a physiotherapist and an occupational therapist assessed 62 people with severe mental illness. Physical fitness was measured with a range of 11 fitness tests that covered flexibility, strength, balance, and endurance. To assess quality of life the EQ-5D-3 L scale was used, which measures five dimensions (mobility, self-care, usual activities, pain-discomfort, and anxiety-depression). Significant correlations are presented between the quality of life and primary variables of physical fitness (balance, endurance, and upper limb strength). Endurance explained 22.9% of the variance of the quality of life in people with severe mental illness. Functional reach added another 36.2% variance to the prediction of quality of life. The results of the present study suggest that some variables of physical fitness are associated with quality of life in people with severe mental illness. The improvement in physical fitness of this population should be a primary objective. ClinicalTrials.gov Identifier: NCT02413164 "retrospective registered" Registered Febr 2017.

Laterality, 2(2), 81-89] and Cornish, Pigram, and Shaw [(1997). Do anomalies of handedness exist in children with fragile-X syndrome? Laterality, 2(2), 91-101], the aim of this paper was to determine laterality in people with fragile X syndrome (FXS). The sample comprised three study groups: the first with 30 people with FXS (mean age 17.9 years), the second 34 people with various intellectual disabilities (ID, mean age 20.9 years), and the third 160 people with typical development (mean age 14.7 years). Laterality was assessed with a test adapted for this study. The results confirm the preponderance of right-handedness (93.3%) in people with FXS and present new data regarding footedness and sensory dominance (eyedness and earedness), indicating inconsistent footedness and ocular cross-dominance. Almost three-quarters (73.5%) of people with other ID were right-handed. The results corroborate those of McManus and Cornish (1997). People with FXS tend to be right-handed but have ocular cross-dominance.

Access to expert stroke care with telemedicine: REACH MUSC
Directory of Open Access Journals (Sweden)
Abby Swanson Kazley
2012-03-01
Full Text Available Stroke is a leading cause of death and disability, and rtPA can significantly reduce the long-term impact of acute ischemic stroke (AIS if given within 3 hours of symptom onset. South Carolina is located in the stroke belt and has a high rate of stroke and stroke mortality. Many small rural SC hospitals do not maintain the expertise needed to treat AIS patients with rtPA. MUSC is an academic medical center using REACH MUSC telemedicine to deliver stroke care to 15 hospitals in the state, increasing the likelihood of timely treatment with rtPA. The purpose of this study is to determine the increase in access to rtPA through the use of telemedicine for AIS in the general population and in specific segments of the population based on age, gender, race, ethnicity, education, urban/rural residence, poverty, and stroke mortality.We used a retrospective cross-sectional design examining Census data from 2000 and Geographic Information Systems (GIS analysis to identify South Carolina residents that live within 30 or 60 minutes of a Primary Stroke Center (PSC or a REACH MUSC site. We include all South Carolina citizens in our analysis and specifically examine the population’s age, gender, race, ethnicity, education, urban/rural residence, poverty, and stroke mortality. Our sample includes 4,012,012 South Carolinians. The main measure is access to expert stroke care at a Primary Stroke Center (PSC or a REACH MUSC hospital within 30 or 60 minutes. We find that without REACH MUSC, only 38% of the population has potential access to expert stroke care in SC within sixty minutes given that most PSCs will maintain expert stroke coverage. REACH MUSC allows 76% of the population to be within sixty minutes of expert stroke care, and 43% of the population to be within 30 minute drive time of expert stroke care. These increases in access are especially significant for groups that have faced disparities in care and high rates of AIS. The use of telemedicine can

This study tested the use of a customized body-machine interface (BoMI) for enhancing functional capabilities in persons with cervical spinal cord injury (cSCI). The interface allows people with cSCI to operate external devices by reorganizing their residual movements. This was a proof-of-concept phase 0 interventional nonrandomized clinical trial. Eight cSCI participants wore a custom-made garment with motion sensors placed on the shoulders. Signals derived from the sensors controlled a computer cursor. A standard algorithm extracted the combinations of sensor signals that best captured each participant's capacity for controlling a computer cursor. Participants practiced with the BoMI for 24 sessions over 12 weeks performing 3 tasks: reaching, typing, and game playing. Learning and performance were evaluated by the evolution of movement time, errors, smoothness, and performance metrics specific to each task. Through practice, participants were able to reduce the movement time and the distance from the target at the 1-second mark in the reaching task. They also made straighter and smoother movements while reaching to different targets. All participants became faster in the typing task and more skilled in game playing, as the pong hit rate increased significantly with practice. The results provide proof-of-concept for the customized BoMI as a means for people with absent or severely impaired hand movements to control assistive devices that otherwise would be manually operated.

Interrupted object-based updating of reach program leads to a negative compatibility effect.
Vainio, Lari
2009-07-01
The author investigated how the motor program elicited by an object's orientation is updated by object-based information while a participant reaches for the object. Participants selected the hand of response according to the thickness of the graspable object and then reached toward the location in which the object appeared. Reach initiation times decreased when the handle of the object was oriented toward the responding hand. This positive compatibility effect turned into a negative compatibility effect (NCE) during reach execution when the object was removed from the display 300 ms after object onset or replaced with a mask at movement onset. The results demonstrate that interrupted object-based updating of an ongoing reach movement triggers the NCE.

Following an increase in tobacco consumption among 12 to 17 year olds between 1993 and 1997, a policy mix comprising various structural and behavioral prevention measures was implemented in Germany. One element of this policy mix is the "rauchfrei" ("smoke-free") youth campaign of the BZgA (Federal Centre for Health Education), a combination of media that reaches a large number of youth, personal communication, and setting-based interventions. The aim is to prevent young people from starting to smoke and to promote the cessation of smoking at an early stage. Based on a multistage intervention model, wide coverage of the measures should be achieved among young people, as well as changes in knowledge, attitudes, social norms, and behavioral intentions. Based on the intervention model, repeated, representative cross-sectional surveys were conducted to examine the development of these indicators and of tobacco consumption. Five studies were conducted during the period from 2003 to 2008, each comprising between 1,220 and 2,780 computer-assisted telephone interviews with randomly selected young people between the ages of 12 and 17. The percentage of young people reached by information offered on the subject of not smoking rose between 2003 and 2008. Participation in school-based prevention measures also rose. There was an increase in knowledge regarding the harmful substances contained in cigarette smoke, and in the percentage of young people who rated active and passive smoking as being harmful to health. In addition, the attitude towards smoking of young people who have never smoked became more critical, as did that perceived in the social environment. The proportion of young people who smoke declined substantially, from 27.5% (2001) to 15.4% (2008), and there was been a major rise in the number who have never smoked, from 40.5% (2001) to 60.6% (2008). The change in knowledge-based risk assessments, attitudes, and social norms should be further promoted by mass media

Do older adults perceive postural constraints for reach estimation?
Cordova, Alberto; Gabbard, Carl
2014-01-01
BACKGROUND/STUDY CONTEXT: Recent evidence indicates that older persons have difficulty mentally representing intended movements. Furthermore, in an estimation of reach paradigm using motor imagery, a form of mental representation, older persons significantly overestimated their ability compared with young adults. The authors tested the notion that older adults may also have difficulty perceiving the postural constraints associated with reach estimation. The authors compared young (Mage = 22 years) and older (Mage = 67) adults on reach estimation while seated and in a more postural demanding standing and leaning forward position. The expectation was a significant postural effect with the standing condition, as evidenced by reduced overestimation. Whereas there was no difference between groups in the seated condition (both overestimated), older adults underestimated whereas the younger group once again overestimated in the standing condition. From one perspective, these results show that older adults do perceive postural constraints in light of their own physical capabilities. That is, that group perceived greater postural demands with the standing posture and elected to program a more conservative strategy, resulting in underestimation.

Respondent-driven sampling and the recruitment of people with small injecting networks.
Paquette, Dana; Bryant, Joanne; de Wit, John
2012-05-01
Respondent-driven sampling (RDS) is a form of chain-referral sampling, similar to snowball sampling, which was developed to reach hidden populations such as people who inject drugs (PWID). RDS is said to reach members of a hidden population that may not be accessible through other sampling methods. However, less attention has been paid as to whether there are segments of the population that are more likely to be missed by RDS. This study examined the ability of RDS to capture people with small injecting networks. A study of PWID, using RDS, was conducted in 2009 in Sydney, Australia. The size of participants' injecting networks was examined by recruitment chain and wave. Participants' injecting network characteristics were compared to those of participants from a separate pharmacy-based study. A logistic regression analysis was conducted to examine the characteristics independently associated with having small injecting networks, using the combined RDS and pharmacy-based samples. In comparison with the pharmacy-recruited participants, RDS participants were almost 80% less likely to have small injecting networks, after adjusting for other variables. RDS participants were also more likely to have their injecting networks form a larger proportion of those in their social networks, and to have acquaintances as part of their injecting networks. Compared to those with larger injecting networks, individuals with small injecting networks were equally likely to engage in receptive sharing of injecting equipment, but less likely to have had contact with prevention services. These findings suggest that those with small injecting networks are an important group to recruit, and that RDS is less likely to capture these individuals.

Prediction of Reach Goals in Depth and Direction from the Parietal Cortex
Directory of Open Access Journals (Sweden)
Matteo Filippini
2018-04-01
Full Text Available Summary: The posterior parietal cortex is well known to mediate sensorimotor transformations during the generation of movement plans, but its ability to control prosthetic limbs in 3D environments has not yet been fully demonstrated. With this aim, we trained monkeys to perform reaches to targets located at various depths and directions and tested whether the reach goal position can be extracted from parietal signals. The reach goal location was reliably decoded with accuracy close to optimal (>90%, and this occurred also well before movement onset. These results, together with recent work showing a reliable decoding of hand grip in the same area, suggest that this is a suitable site to decode the entire prehension action, to be considered in the development of brain-computer interfaces. : Filippini et al. show that it is possible to use parietal cortex activity to predict in which direction the arm will move and how far it will reach. This opens up the possibility of neural prostheses that can accurately guide reach and grasp using signals from this part of the brain. Keywords: neuroprosthetics, offline neural decoding, reaching in depth, monkey, V6A, machine learning, visuomotor transformations, hand guidance, prehension, robotics

Contribution of River Mouth Reach to Sediment Load of the Yangtze River
Directory of Open Access Journals (Sweden)
C. Wang
2015-01-01
Full Text Available This paper examined the sediment gain and loss in the river mouth reach of the Yangtze River by considering sediment load from the local tributaries, erosion/accretion of the river course, impacts of sand mining, and water extraction. A quantitative estimation of the contribution of the river mouth reach to the sediment load of the Yangtze River was conducted before and after impoundment of the Three Gorges Dam (TGD in 2003. The results showed that a net sediment load loss of 1.78 million ton/yr (Mt/yr occurred from 1965 to 2002 in the study area. The contribution of this reach to the sediment discharge into the sea is not as high as what was expected before the TGD. With impoundment of the TGD, channel deposition (29.90 Mt/yr and a net sediment loss of 30.89 Mt/yr occurred in the river mouth reach from 2003 to 2012. The river mouth reach has acted as a sink but not a source of sediment since impoundment of the TGD, which has exacerbated the decrease in sediment load. Technologies should be advanced to measure changes in river channel morphology, as well as in water and sediment discharges at the river mouth reach.

Being homeless or vulnerably housed is associated with death at a young age, frequently related to medical problems complicated by drug or alcohol dependence. Homeless people experience high symptom burden at the end of life, yet palliative care service use is limited. To explore the views and experiences of current and formerly homeless people, frontline homelessness staff (from hostels, day centres and outreach teams) and health- and social-care providers, regarding challenges to supporting homeless people with advanced ill health, and to make suggestions for improving care. Thematic analysis of data collected using focus groups and interviews. Single homeless people ( n = 28), formerly homeless people ( n = 10), health- and social-care providers ( n = 48), hostel staff ( n = 30) and outreach staff ( n = 10). This research documents growing concern that many homeless people are dying in unsupported, unacceptable situations. It highlights the complexities of identifying who is palliative and lack of appropriate places of care for people who are homeless with high support needs, particularly in combination with substance misuse issues. Due to the lack of alternatives, homeless people with advanced ill health often remain in hostels. Conflict between the recovery-focused nature of many services and the realities of health and illness for often young homeless people result in a lack of person-centred care. Greater multidisciplinary working, extended in-reach into hostels from health and social services and training for all professional groups along with more access to appropriate supported accommodation are required to improve care for homeless people with advanced ill health.

Let's talk sex on the air: ReachOut launches radio campaign.
This article reports on the launching of the National Radio and Public Relations Campaign to Promote Modern Methods of Contraception by the ReachOut AIDS Foundation Incorporated in the Philippines. ReachOut has tapped radio veteran Tiya Dely Magpayo as the official campaign spokesperson, thus, putting a mother's touch to a serious promotional drive to reach the far-flung areas of the country. It is noted that the project promotes the wider use of modern methods of contraception as its contribution to the Philippines Population Program goals of controlling the population rate. Since radio is the most patronized media in the country, ReachOut hopes that the radio soap opera format will attract the listeners to use contraceptives. The campaign encourages men and women of reproductive age to seek information and services regarding modern methods of contraception from health service providers in their respective areas. The Department of Health will provide the technical support to ensure that the campaign is keeping with the government's programs.

The German REACH Congress 2016: a workshop report.
Reihlen, Antonia; Jepsen, Dirk; Broschinski, Lutz; Luch, Andreas; Schulte, Agnes
2018-03-01
In October 2016, the German REACH Congress was held at the German Federal Institute for Risk Assessment (BfR) in Berlin. Here, the associated improvement made in the fields of consumer protection and the progress in and experiences gained from the implementation of the authorisation procedure were discussed. Several speakers from EU institutions, German authorities, industry, and civil society organisations were invited to present their views. There was a shared consensus that REACH contributes to the advancement of consumer protection against chemical risks, mainly because more and higher quality information on substance-related hazards and potential exposures becomes available. In addition, risk management measures, particularly regarding restrictions on uses, scale down consumer exposures to chemicals. Opportunities for improvements identified at the congress include the quality of registration dossiers and the management of and communication on substances of very high concern (SVHC) that may be present in consumer articles. Although regarded as being in an early implementation phase, the authorisation process was generally found to be operational and progressing well. Criticism was expressed with regard to the consistency of authorisation decisions and the costs and uncertainties related to authorisation applications. Consumer protection legislation consists of several legal provisions which are interlinked. The congress participants agreed that REACH is an important element of this legal framework as it enhances and complements other legal provisions.

Distractor interference during a choice limb reaching task.
Directory of Open Access Journals (Sweden)
Matthew Ray
Full Text Available According to action-centered models of attention, the patterns of distractor interference that emerge in selective reaching tasks are related to the time and effort required to resolve a race for activation between competing target and non-target response producing processes. Previous studies have only used unimanual aiming tasks and, as such, only examined the effects of competition that occurs within a limb. The results of studies using unimanual aiming movements often reveal an "ipsilateral effect"--distractors on the same side of space as the effector cause greater interference than distractors on the opposite side of space. The cost of the competition when response selection is between the limbs has yet to be addressed. Participants in the present study executed reaching movements to 1 of 4 (2 left, 2 right possible target locations with and without a distractor. Participants made ipsilateral reaches (left hand to left targets, right hand to right targets. In contrast to studies using unimanual aiming movements, a "contralateral effect" was observed; distractors affording responses for the other hand (in contralateral space caused more interference than distractors affording responses for the same hand. The findings from the present research demonstrate that when certain portions of response planning must be resolved prior to response initiation, distractors that code for that dimension cause the greatest interference.

Infant manual performance during reaching and grasping for objects moving in depth.
Domellöf, Erik; Barbu-Roth, Marianne; Rönnqvist, Louise; Jacquet, Anne-Yvonne; Fagard, Jacqueline
2015-01-01
Few studies have investigated manual performance in infants when reaching and grasping for objects moving in directions other than across the fronto-parallel plane. The present preliminary study explored object-oriented behavioral strategies and side preference in 8- and 10-month-old infants during reaching and grasping for objects approaching in depth from three positions (midline, and 27° diagonally from the left and right). Effects of task constraint by using objects of three different types and two sizes were further examined for behavioral strategies and hand opening prior to grasping. Additionally, assessments of hand preference by a dedicated handedness test were performed. Regardless of object starting position, the 8-month-old infants predominantly displayed right-handed reaches for objects approaching in depth. In contrast, the older infants showed more varied strategies and performed more ipsilateral reaches in correspondence with the side of the approaching object. Conversely, 10-month-old infants were more successful than the younger infants in grasping the objects, independent of object starting position. The findings regarding infant hand use strategies when reaching and grasping for objects moving in depth are similar to those from earlier studies using objects moving along a horizontal path. Still, initiation times of reaching onset were generally long in the present study, indicating that the object motion paths seemingly affected how the infants perceived the intrinsic properties and spatial locations of the objects, possibly with an effect on motor planning. Findings are further discussed in relation to future investigations of infant reaching and grasping for objects approaching in depth.

Despite the increasing number of specialized addiction services and the constant deployment of health care resources, a coordinated needs-based treatment is not always available for people with severe drugs and/or alcohol problems. Too often the involved health care professionals feel helpless and overwhelmed by the complexity of the situation. In order to promote the treatment engagement of the hard-to-reach substance users, a multidisciplinary mobile team project for addiction (SIMA) was developed in Lausanne, Switzerland, in 20174. This paper describes the model of intervention, the profile of the population followed during the first year of intervention and illustrates, through two clinical cases, the advantages of this approach.

Effect of tonic pain on motor acquisition and retention while learning to reach in a force field.
Directory of Open Access Journals (Sweden)
Mélanie Lamothe
Full Text Available Most patients receiving intensive rehabilitation to improve their upper limb function experience pain. Despite this, the impact of pain on the ability to learn a specific motor task is still unknown. The aim of this study was to determine whether the presence of experimental tonic pain interferes with the acquisition and retention stages of motor learning associated with training in a reaching task. Twenty-nine healthy subjects were randomized to either a Control or Pain Group (receiving topical capsaicin cream on the upper arm during training on Day 1. On two consecutive days, subjects made ballistic movements towards two targets (NEAR/FAR using a robotized exoskeleton. On Day 1, the task was performed without (baseline and with a force field (adaptation. The adaptation task was repeated on Day 2. Task performance was assessed using index distance from the target at the end of the reaching movement. Motor planning was assessed using initial angle of deviation of index trajectory from a straight line to the target. Results show that tonic pain did not affect baseline reaching. Both groups improved task performance across time (p<0.001, but the Pain group showed a larger final error (under-compensation than the Control group for the FAR target (p = 0.030 during both acquisition and retention. Moreover, a Group x Time interaction (p = 0.028 was observed on initial angle of deviation, suggesting that subjects with Pain made larger adjustments in the feedforward component of the movement over time. Interestingly, behaviour of the Pain group was very stable from the end of Day 1 (with pain to the beginning of Day 2 (pain-free, indicating that the differences observed could not solely be explained by the impact of pain on immediate performance. This suggests that if people learn to move differently in the presence of pain, they might maintain this altered strategy over time.

A survey of redundant facilities at Sellafield has identified that in many cases the conventional means of deploying remote handling equipment are not appropriate and that novel means must be employed. However, decommissioning is not a value adding activity and so expensive one off designs must be avoided. The paper will describe BNFL's approach to the synthesis from proprietary parts of a manipulator which can lift 3 te at a horizontal reach of over 5 metres and yet can still perform the dextrous manipulation necessary to remove small items. It will also cover the development of the manipulator control systems and the adaption of commercial handtools to be manipulator friendly. (author)

Grip type and task goal modify reach-to-grasp performance in post-stroke hemiparesis
Schaefer, Sydney Y.; DeJong, Stacey L.; Cherry, Kendra M.; Lang, Catherine E.
2011-01-01
This study investigated whether grip type and/or task goal influenced reaching and grasping performance in post-stroke hemiparesis. Sixteen adults with post-stroke hemiparesis and twelve healthy adults reached to and grasped a cylindrical object using one of two grip types (3-finger or palmar) to achieve one of two task goals (hold or lift). Performance of the stroke group was characteristic of hemiparetic limb movement during reach-to-grasp, with more curved handpaths and slower velocities compared to the control group. These effects were present regardless of grip type or task goal. Other measures of reaching (reach time and reach velocity at object contact) and grasping (peak thumb-index finger aperture during the reach and peak grip force during the grasp) were differentially affected by grip type, task goal, or both, despite the presence of hemiparesis, providing new evidence that changes in motor patterns after stroke may occur to compensate for stroke-related motor impairment.

[Purpose] The increase in the Taiwanese older population is associated with age-related inconveniences. Finding adequate and simple physical activities to help the older people maintaining their physiological function and preventing them from falls has become an urgent social issue. [Subjects and Methods] This study aimed to design a virtual exercise training game suitable for Taiwanese older people. This system will allow for the maintenance of the physiological function and standing stability through physical exercise, while using a virtual reality game. The participants can easily exercise in a carefree, interactive environment. This study will use Kinect for Windows for physical movement detection and Unity software for virtual world development. [Results] Group A and B subjects were involved in the exercise training method of Kinect interactive multimedia for 12 weeks. The results showed that the functional reach test and the unipedal stance test improved significantly. [Conclusion] The physiological function and standing stability of the group A subjects were examined at six weeks post training. The results showed that these parameters remained constant. This proved that the proposed system provide substantial support toward the preservation of the Taiwanese older people' physiological function and standing stability.

Taking family planning services to hard-to-reach populations.
Donovan, P
1996-01-01
Interviews were conducted in 1995 among 100 US family planning program personnel who serve hard-to-reach populations, such as drug abusers, prisoners, the disabled, homeless persons, and non-English speaking minorities. Findings indicate that a range of services is available for hard-to-reach groups. Most family planning agencies focus on drug abusers because of the severity of HIV infections and the availability of funding. This article describes the activities of various agencies in Michigan, Pennsylvania, and Massachusetts that serve substance abuse centers with family planning services. One recommendation for a service provider is to present services in an environment where it is safe to talk about a person's needs. One other program offered personal greetings upon arrival and the continuity of having a familiar face to oversee all reproductive and health needs. Programs for prisoners ranged from basic sex education classes to comprehensive reproductive health care. Some prisons offered individual counseling. Some programs were presented in juvenile offender facilities. Outreach to the homeless involved services at homeless shelters, outreach workers who recruited women into traditional family planning clinics, and establishment of nontraditional sites for the homeless and other hard-to-reach persons. One provider's suggestion was to offer services where high-risk women already go for other services. Most services to the disabled target the developmentally disabled rather than the physically disabled. Experience has shown that many professionals working with the disabled do not recognize their clients' sexual needs. Other hard-to-reach groups include women in housing projects and shelters for battered women, welfare applicants, and sex workers. Key to service provision is creating trust, overcoming language and cultural differences, and subsidizing the cost of care.

Workspace location influences joint coordination during reaching in post-stroke hemiparesis
Reisman, Darcy S.; Scholz, John P.
2006-01-01
The purpose of this study was to determine the influence of workspace location on joint coordination in persons with post-stroke hemiparesis when trunk motion was required to complete reaches beyond the arm’s functional reach length. Seven subjects with mild right hemiparesis following a stroke and seven age and gender matched control subjects participated. Joint motions and characteristics of hand and trunk movement were measured over multiple repetitions. The variance (across trials) of joint combinations was partitioned into two components at every point in the hand’s trajectory using the uncontrolled manifold approach; the first component is a measure of the extent to which equivalent joint combinations are used to control a given hand path, and reflects performance flexibility. The second component of joint variance reflects the use of non-equivalent joint combinations, which lead to hand path error. Compared to the control subjects, persons with hemiparesis demonstrated a significantly greater amount of non-equivalent joint variability related to control of the hand’s path and of the hand’s position relative to the trunk when reaching toward the hemiparetic side (ipsilaterally), but not when reaching to the less involved side. The relative timing of the hand and trunk was also altered when reaching ipsilaterally. The current findings support the idea that the previously proposed “arm compensatory synergy” may be deficient in subjects with hemiparesis. This deficiency may be due to one or a combination of factors: changes in central commands that are thought to set the gain of the arm compensatory synergy; a limited ability to combine shoulder abduction and elbow extension that limits the expression of an appropriately set arm compensatory synergy; or a reduction of the necessary degrees-of-freedom needed to adequately compensate for poor trunk control when reaching ipsilaterally.

Full Text Available People-to-people exchange has become a heated topic of the Chinese foreign policy. Since the beginning of the twenty-first century, China has established people-to-people dialogues with the United States, the European Union, the United Kingdom, France and Russia. In 2012, China and the EU established a high-level dialogue for people-to-people exchange, making people-to-people exchange the third pillar of China-EU relations. However, China is not a newcomer to people-to-people exchanges with Europe. Why does China launch the people-to-people diplomacy? Is it a plus or a must for China as well as for China-EU relations? The author reviews the history and current situation of China's people-to-people exchange and investigates China’s motivations behind the policy. Using the historical institutionalism as an approach, this paper argues that people-to-people diplomacy is a key component of the contemporary Chinese foreign policy towards Europe. China has long been an unequal counterpart to Europe since the 1840s. After the development of bilateral political and economic cooperation in the past four decades, people-to-people diplomacy is the last part that China needs to finish in order to regain equal status with Europe. In addition, it is also a step towards realising the "great rejuvenation of the Chinese nation".

In the United States, National Chemistry Week is November 7-13. (For more NCW information, go to http://www.acs.org/ncw/.) NCW's theme, celebrating polymers, is echoed in this issue (pages 1497-1501, 1512-1513, 1521-1540). Almost certainly there will be chemists in your area spending a great deal of their time on outreach activities for children and the general public during NCW. Chances are good that many Journal readers like you will be among them. And there are probably many more outreach programs that you or your acquaintances lead during the rest of the year. This month of NCW seems an appropriate time to reflect on the tremendous benefits that outreach programs provide. Early examples of outreach involved books, public lectures, and chemical demonstrations. In 1800 Count Rumford collaborated with influential Londoners to establish the Royal Institution as a means of providing lectures on science and technology to help working people to improve their lot. Humphry Davy, Michael Faraday, and many others continued the tradition. Faraday's own interest in science was sparked in part by Jane Marcet's book Conversations in Chemistry, whose friendly style made its contents accessible and fascinating to the young, highly intelligent bookbinder's apprentice. In the United States, Benjamin Silliman, first professor of chemistry at Yale, became widely known for his textbooks on geology and chemistry and for his ability as a popular lecturer. Silliman's lecture tours took him as far from New Haven as St. Louis and New Orleans. By the mid-1800s societies for the advancement of science and of chemistry were being set up in Europe. In 1876 American chemists who gathered at Priestley's grave in Northumberland, Pennsylvania, to commemorate the centennial of the discovery of oxygen saw the need for a permanent organization and founded the American Chemical Society. By the beginning of the 20th century these societies were supporting education and public awareness of science

To evaluate factors associated with reaching or not reaching target glycated haemoglobin (HbA 1c ) levels by analysing the respective contributions of fasting hyperglycaemia (FHG), also referred to as basal hyperglycaemia, vs postprandial hyperglycaemia (PHG) before and after initiation of a basal or premixed insulin regimen in patients with type 2 diabetes. This post-hoc analysis of insulin-naïve patients in the DURABLE study randomised to receive either insulin glargine or insulin lispro mix 25 evaluated the percentages of patients achieving a target HbA 1c of <7.0% (<53mmol/mol) per baseline HbA 1c quartiles, and the effect of each insulin regimen on the relative contributions of PHG and FHG to overall hyperglycaemia. Patients had comparable demographic characteristics and similar HbA 1c and FHG values at baseline in each HbA 1c quartile regardless of whether they reached the target HbA 1c . The higher the HbA 1c quartile, the greater was the decrease in HbA 1c , but also the smaller the percentage of patients achieving the target HbA 1c . HbA 1c and FHG decreased more in patients reaching the target, resulting in significantly lower values at endpoint in all baseline HbA 1c quartiles with either insulin treatment. Patients not achieving the target HbA 1c had slightly higher insulin doses, but lower total hypoglycaemia rates. Smaller decreases in FHG were associated with not reaching the target HbA 1c , suggesting a need to increase basal or premixed insulin doses to achieve targeted fasting plasma glucose and improve patient response before introducing more intensive prandial insulin regimens.

The neural control of this coordination is quite complex because the various body parts have their own kinematic and dynamic properties. Behavioral inferences about the neural solution to the coordination problem could be obtained by examining the emerging phase relationship and its stability. Here, we studied the phase relationships that characterize the coordination of arm-reaching movements with passively-induced whole-body motion. Participants were laterally translated using a vestibular chair that oscillated at a fixed frequency of 0.83 Hz. They were instructed to reach between two targets that were aligned either parallel or orthogonal to the whole body motion. During the first cycles of body motion, a metronome entrained either an in-phase or an anti-phase relationship between hand and body motion, which was released at later cycles to test phase stability. Results suggest that inertial forces play an important role when coordinating reaches with cyclic whole-body motion. For parallel reaches, we found a stable in-phase and an unstable anti-phase relationship. When the latter was imposed, it readily transitioned or drifted back toward an in-phase relationship at cycles without metronomic entrainment. For orthogonal reaches, we did not find a clear difference in stability between in-phase and anti-phase relationships. Computer simulations further show that cost models that minimize energy expenditure (i.e. net torques or endpoint variance of the reach cannot fully explain the observed coordination patterns. We discuss how predictive control and impedance control processes could be considered important mechanisms underlying the rhythmic coordination of arm reaches and body motion.

Full Text Available Few studies have observed investigated manual asymmetries performance in infants when reaching and grasping for objects moving in directions other than across the fronto-parallel plane. The present preliminary study explored manual object-oriented behavioral strategies and hand side preference in 8- and 10-month-old infants during reaching and grasping for objects approaching in depth from three positions (midline, and 27° diagonally from the left, and right, midline. Effects of task constraint by using objects of three different types and two sizes were further examined for behavioral strategies and . The study also involved measurements of hand position opening prior to grasping., and Additionally, assessments of general hand preference by a dedicated handedness test were performed. Regardless of object starting position, the 8-month-old infants predominantly displayed right-handed reaches for objects approaching in depth. In contrast, the older infants showed more varied strategies and performed more ipsilateral reaches in correspondence with the side of the approaching object. Conversely, 10-month-old infants were more successful than the younger infants in grasping the objects, independent of object starting position. The findings support the possibility of a shared underlying mechanism regarding for infant hand use strategies when reaching and grasping for horizontally objects moving in depth are similar to those from earlier studies using objects moving along a horizontal pathand vertically moving objects. Still, initiation times of reaching onset were generally long in the present study, indicating that the object motion paths seemingly affected how the infants perceived the intrinsic properties and spatial locations of the objects, possibly with an effect on motor planning. Findings are further discussed in relation to future investigations of infant reaching and grasping for objects approaching in depth.

Action without awareness: reaching to an object you do not remember seeing.
Directory of Open Access Journals (Sweden)
Matthew Heath
Full Text Available BACKGROUND: Previous work by our group has shown that the scaling of reach trajectories to target size is independent of obligatory awareness of that target property and that "action without awareness" can persist for up to 2000 ms of visual delay. In the present investigation we sought to determine if the ability to scale reaching trajectories to target size following a delay is related to the pre-computing of movement parameters during initial stimulus presentation or the maintenance of a sensory (i.e., visual representation for on-demand response parameterization. METHODOLOGY/PRINCIPAL FINDINGS: Participants completed immediate or delayed (i.e., 2000 ms perceptual reports and reaching responses to different sized targets under non-masked and masked target conditions. For the reaching task, the limb associated with a trial (i.e., left or right was not specified until the time of response cuing: a manipulation that prevented participants from pre-computing the effector-related parameters of their response. In terms of the immediate and delayed perceptual tasks, target size was accurately reported during non-masked trials; however, for masked trials only a chance level of accuracy was observed. For the immediate and delayed reaching tasks, movement time as well as other temporal kinematic measures (e.g., times to peak acceleration, velocity and deceleration increased in relation to decreasing target size across non-masked and masked trials. CONCLUSIONS/SIGNIFICANCE: Our results demonstrate that speed-accuracy relations were observed regardless of whether participants were aware (i.e., non-masked trials or unaware (i.e., masked trials of target size. Moreover, the equivalent scaling of immediate and delayed reaches during masked trials indicates that a persistent sensory-based representation supports the unconscious and metrical scaling of memory-guided reaching.

Coffee, Cake & Culture: Evaluation of an art for health programme for older people in the community.
Roe, Brenda; McCormick, Sheila; Lucas, Terri; Gallagher, Wendy; Winn, Andrea; Elkin, Sophie
2016-07-01
Arts for health initiatives and networks are being developed in a number of countries and an international literature is emerging on the evidence of their benefits to people's health, wellbeing and quality of life. Engagement in cultural and creative arts by older people can increase their morale and self-confidence and provides opportunities for social connection. Museums and galleries are increasingly required to justify their expenditure, reach and impact and some are working in partnership with local councils, hospitals, schools and communities to improve access to their collections. There is a body of literature emerging that describes such initiatives but empirical evidence of their benefits is less developed. This article reports an evaluation of an art for health initiative - Coffee, Cake & Culture organised and delivered by Whitworth Art Gallery and Manchester Museum in 2012 for older people living in a care home and a supported living facility. The study has identified the benefits and impacts of the arts for health programme and its feasibility for older people, with or without diagnosed memory loss - dementia, living in a care home or supported living facility and their care staff. The findings demonstrate there were benefits to the older people and their care staff in terms of wellbeing, social engagement, learning, social inclusion and creativity. These benefits were immediate and continued in the short term on their return home. The majority of older people and care staff had not previously been to the art gallery or museum and the programme encouraged creative arts and cultural appreciation which promoted social inclusion, wellbeing and quality of life. The programme is feasible and important lessons were identified for future planning. Further research involving partnerships of researchers, arts for health curators, artists, care staff, older people and their families is warranted. © The Author(s) 2014.

Reach-to-grasp movements feature the integration of a reach directed by the extrinsic (location) features of a target and a grasp directed by the intrinsic (size, shape) features of a target. The action-perception theory suggests that integration and scaling of a reach-to-grasp movement, including its trajectory and the concurrent digit shaping, are features that depend upon online action pathways of the dorsal visuomotor stream. Scaling is much less accurate for a pantomime reach-to-grasp movement, a pretend reach with the target object absent. Thus, the action-perception theory proposes that pantomime movement is mediated by perceptual pathways of the ventral visuomotor stream. A distinguishing visual feature of a real reach-to-grasp movement is gaze anchoring, in which a participant visually fixates the target throughout the reach and disengages, often by blinking or looking away/averting the head, at about the time that the target is grasped. The present study examined whether gaze anchoring is associated with pantomime reaching. The eye and hand movements of participants were recorded as they reached for a ball of one of three sizes, located on a pedestal at arms' length, or pantomimed the same reach with the ball and pedestal absent. The kinematic measures for real reach-to-grasp movements were coupled to the location and size of the target, whereas the kinematic measures for pantomime reach-to-grasp, although grossly reflecting target features, were significantly altered. Gaze anchoring was also tightly coupled to the target for real reach-to-grasp movements, but there was no systematic focus for gaze, either in relation with the virtual target, the previous location of the target, or the participant's reaching hand, for pantomime reach-to-grasp. The presence of gaze anchoring during real vs. its absence in pantomime reach-to-grasp supports the action-perception theory that real, but not pantomime, reaches are online visuomotor actions and is discussed in

The development of coordinated reach-to-grasp movement has been well studied in infants and children. However, the role of motor cortex during this development is unclear because it is difficult to study in humans. We took the approach of using a brain-machine interface (BMI) paradigm in rhesus macaques with prior therapeutic amputations to examine the emergence of novel, coordinated reach to grasp. Previous research has shown that after amputation, the cortical area previously involved in the control of the lost limb undergoes reorganization, but prior BMI work has largely relied on finding neurons that already encode specific movement-related information. In this study, we taught macaques to cortically control a robotic arm and hand through operant conditioning, using neurons that were not explicitly reach or grasp related. Over the course of training, stereotypical patterns emerged and stabilized in the cross-covariance between the reaching and grasping velocity profiles, between pairs of neurons involved in controlling reach and grasp, and to a comparable, but lesser, extent between other stable neurons in the network. In fact, we found evidence of this structured coordination between pairs composed of all combinations of neurons decoding reach or grasp and other stable neurons in the network. The degree of and participation in coordination was highly correlated across all pair types. Our approach provides a unique model for studying the development of novel, coordinated reach-to-grasp movement at the behavioral and cortical levels. NEW & NOTEWORTHY Given that motor cortex undergoes reorganization after amputation, our work focuses on training nonhuman primates with chronic amputations to use neurons that are not reach or grasp related to control a robotic arm to reach to grasp through the use of operant conditioning, mimicking early development. We studied the development of a novel, coordinated behavior at the behavioral and cortical level, and the neural

Mechanical energy expenditures and movement efficiency in full body reaching movements.
Sha, Daohang; France, Christopher R; Thomas, James S
2010-02-01
The effect of target location, speed, and handedness on the average total mechanical energy and movement efficiency is studied in 15 healthy subjects (7 males and 8 females with age 22.9 +/- 1.79 years old) performing full body reaching movements. The average total mechanical energy is measured as the time average of integration of joint power, potential energy, and kinetic energy respectively. Movement efficiency is calculated as the ratio of total kinetic energy to the total joint power and potential energy. Results show that speed and target location have significant effects on total mechanical energy and movement efficiency, but reaching hand only effects kinetic energy. From our findings we conclude that (1) efficiency in whole body reaching is dependent on whether the height of the body center of mass is raised or lowered during the task; (2) efficiency is increased as movement speed is increased, in part because of greater changes in potential energy; and (3) the CNS does not appear to use movement efficiency as a primary planning variable in full body reaching. It may be dependent on a combination of other factors or constraints.

Sliding Mode Tracking Control of Manipulator Based on the Improved Reaching Law

Wei-Na ZHAI
2013-04-01
Full Text Available Due to the mechanical hand often have serious uncertainty, as the state in which the different and external changes, also its parameters are changing, this is very adverse to achieve precise control. In this paper, the traditional sliding mode variable structure was improved, the sign function is replaced by saturated function based on the double power reaching law, by adjusting the values of e1, e2, a, b, g and k to effectively improve the manipulator joint reaching speed, track expected trajectory fast and shorten the system response time. Finally, the method is used for simulation of manipulator trajectory tracking, compared to two reaching law control algorithms. The simulation results show that the control algorithm has good dynamic performance, which can effectively restrain the chattering and quickly track the desired trajectory. Therefore, the improved reaching law can effectively improve the performance of robotic manipulator.

Public health policy calls for intervention programmes to reduce loneliness in the ageing population. So far, numerous loneliness interventions have been developed, with effectiveness demonstrated for few of these interventions. The loneliness intervention described in this manuscript distinguishes itself from others by including multiple intervention components and targeting individuals and their environment. Intervention components included a mass media campaign, information meetings, psychosocial group courses, social activities organised by neighbours, and training of intermediaries. The aim of this manuscript is to study the effects of this integrated approach on initial and long-term outcomes. A quasi-experimental pre-test post-test intervention study was conducted among non-institutionalised elderly people aged 65 years and over to evaluate the effectiveness of the intervention by comparing the intervention community and the control community. Data on outputs, initial and long-term outcomes, and the overall goal were collected by self-administered questionnaires. Data of 858 elderly people were available for the analyses. To assess the effect linear regression analyses with adjustments for age, gender, church attendance, and mental health were used. In addition, the process evaluation provided information about the reach of the intervention components. After two years, 39% of the elderly people were familiar with the intervention programme. The intervention group scored more favourably than the control group on three subscales of the initial outcome, motivation (-4.4%, 95% CI-8.3--0.7), perceived social support (-8.2%, 95% CI-13.6--2.4), and subjective norm (-11.5%, 95% CI-17.4--5.4). However, no overall effects were observed for the long-term outcome, social support, and overall goal, loneliness. Two years after its initiation the reach of the intervention programme was modest. Though no effect of the complex intervention was found on social support and

Patterns of arm muscle activation involved in octopus reaching movements.
Gutfreund, Y; Flash, T; Fiorito, G; Hochner, B
1998-08-01
The extreme flexibility of the octopus arm allows it to perform many different movements, yet octopuses reach toward a target in a stereotyped manner using a basic invariant motor structure: a bend traveling from the base of the arm toward the tip (Gutfreund et al., 1996a). To study the neuronal control of these movements, arm muscle activation [electromyogram (EMG)] was measured together with the kinematics of reaching movements. The traveling bend is associated with a propagating wave of muscle activation, with maximal muscle activation slightly preceding the traveling bend. Tonic activation was occasionally maintained afterward. Correlation of the EMG signals with the kinematic variables (velocities and accelerations) reveals that a significant part of the kinematic variability can be explained by the level of muscle activation. Furthermore, the EMG level measured during the initial stages of movement predicts the peak velocity attained toward the end of the reaching movement. These results suggest that feed-forward motor commands play an important role in the control of movement velocity and that simple adjustment of the excitation levels at the initial stages of the movement can set the velocity profile of the whole movement. A simple model of octopus arm extension is proposed in which the driving force is set initially and is then decreased in proportion to arm diameter at the bend. The model qualitatively reproduces the typical velocity profiles of octopus reaching movements, suggesting a simple control mechanism for bend propagation in the octopus arm.

Population ageing fosters new models of care delivery for older people that are increasingly integrated into existing care systems. In the Netherlands, a primary-care based preventive home visitation programme has been developed for potentially frail community-dwelling older people (aged ≥75 years), consisting of a comprehensive geriatric assessment during a home visit by a practice nurse followed by targeted interdisciplinary care and follow-up over time. A theory-based process evaluation was designed to examine (1) the extent to which the home visitation programme was implemented as planned and (2) the extent to which general practices successfully redesigned their care delivery. Using a mixed-methods approach, the focus was on fidelity (quality of implementation), dose delivered (completeness), dose received (exposure and satisfaction), reach (participation rate), recruitment, and context. Twenty-four general practices participated, of which 13 implemented the home visitation programme and 11 delivered usual care to older people. Data collection consisted of semi-structured interviews with practice nurses (PNs), general practitioners (GPs), and older people; feedback meetings with PNs; structured registration forms filled-out by PNs; and narrative descriptions of the recruitment procedures and registration of inclusion and drop-outs by members of the research team. Fidelity of implementation was acceptable, but time constraints and inadequate reach (i.e., the relatively healthy older people participated) negatively influenced complete delivery of protocol elements, such as interdisciplinary cooperation and follow-up of older people over time. The home visitation programme was judged positively by PNs, GPs, and older people. Useful tools were offered to general practices for organising proactive geriatric care. The home visitation programme did not have major shortcomings in itself, but the delivery offered room for improvement. General practices received

REACH Medical University of South Carolina (MUSC) provides stroke consults via the internet in South Carolina. From May 2008 to April 2011 231 patients were treated with intravenous (IV) thrombolysis and 369 were transferred to MUSC including 42 for intra-arterial revascularization [with or without IV tissue plasminogen activator (tPA)]. Medical outcomes and hemorrhage rates, reported elsewhere, were good (Lazaridis et al., 2011). Here we report operational features of REACH MUSC which covers 15 sites with 2,482 beds and 471,875 Emergency Department (ED) visits per year. Eight Academic Faculty from MUSC worked with 165 different physicians and 325 different nurses in the conduct of 1085 consults. For the 231 who received tPA, time milestones (in minutes) were: Onset to Door: 62 (mean), 50 (median); Door to REACH Consult: 43 and 33, Consult Request to Consult Start: was 9 and 7, Consult Start to tPA Decision: 31 and 25; Decision to Infusion: 20 and 14, and total Door to Needle: 98 and 87. The comparable times for the 854 not receiving tPA were: Onset to Door: 140 and 75; Door to REACH Consult: 61 and 41; Consult Request to Consult Start: 9 and 7, Consult Start to tPA Decision: 27 and 23. While the consultants respond to consult requests in <10, there is a long delay between arrival and Consult request. Tracking of operations indicates if we target shortening Door to Call time and time from tPA decision to start of drug infusion we may be able to improve Door to Needle times to target of <60. The large number of individuals involved in the care of these patients, most of whom had no training in REACH usage, will require novel approaches to staff education in ED based operations where turnover is high. Despite these challenges, this robust system delivered tPA safely and in a high fraction of patients evaluated using the REACH MUSC system. PMID:22435064

The mirror game as a paradigm for studying the dynamics of two people improvising motion together
Noy, Lior; Dekel, Erez; Alon, Uri
2011-01-01
Joint improvisation is the creative action of two or more people without a script or designated leader. Examples include improvisational theater and music, and day-to-day activities such as conversations. In joint improvisation, novel action is created, emerging from the interaction between people. Although central to creative processes and social interaction, joint improvisation remains largely unexplored due to the lack of experimental paradigms. Here we introduce a paradigm based on a theater practice called the mirror game. We measured the hand motions of two people mirroring each other at high temporal and spatial resolution. We focused on expert actors and musicians skilled in joint improvisation. We found that players can jointly create novel complex motion without a designated leader, synchronized to less than 40 ms. In contrast, we found that designating one player as leader deteriorated performance: The follower showed 2–3 Hz oscillation around the leader's smooth trajectory, decreasing synchrony and reducing the range of velocities reached. A mathematical model suggests a mechanism for these observations based on mutual agreement on future motion in mirrored reactive–predictive controllers. This is a step toward understanding the human ability to create novelty by improvising together. PMID:22160696

Full Text Available Estimating the size of key risk populations is essential for determining the resources needed to implement effective public health intervention programs. Several standard methods for population size estimation exist, but the statistical and practical assumptions required for their use may not be met when applied to HIV risk groups. We apply three approaches to estimate the number of people who inject drugs (PWID in the Kohtla-Järve region of Estonia using data from a respondent-driven sampling (RDS study: the standard "multiplier" estimate gives 654 people (95% CI 509-804, the "successive sampling" method gives estimates between 600 and 2500 people, and a network-based estimate that uses the RDS recruitment chain gives between 700 and 2800 people. We critically assess the strengths and weaknesses of these statistical approaches for estimating the size of hidden or hard-to-reach HIV risk groups.

Quantitative model of transport-aperture coordination during reach-to-grasp movements.
Rand, Miya K; Shimansky, Y P; Hossain, Abul B M I; Stelmach, George E
2008-06-01
It has been found in our previous studies that the initiation of aperture closure during reach-to-grasp movements occurs when the hand distance to target crosses a threshold that is a function of peak aperture amplitude, hand velocity, and hand acceleration. Thus, a stable relationship between those four movement parameters is observed at the moment of aperture closure initiation. Based on the concept of optimal control of movements (Naslin 1969) and its application for reach-to-grasp movement regulation (Hoff and Arbib 1993), it was hypothesized that the mathematical equation expressing that relationship can be generalized to describe coordination between hand transport and finger aperture during the entire reach-to-grasp movement by adding aperture velocity and acceleration to the above four movement parameters. The present study examines whether this hypothesis is supported by the data obtained in experiments in which young adults performed reach-to-grasp movements in eight combinations of two reach-amplitude conditions and four movement-speed conditions. It was found that linear approximation of the mathematical model described the relationship among the six movement parameters for the entire aperture-closure phase with very high precision for each condition, thus supporting the hypothesis for that phase. Testing whether one mathematical model could approximate the data across all the experimental conditions revealed that it was possible to achieve the same high level of data-fitting precision only by including in the model two additional, condition-encoding parameters and using a nonlinear, artificial neural network-based approximator with two hidden layers comprising three and two neurons, respectively. This result indicates that transport-aperture coordination, as a specific relationship between the parameters of hand transport and finger aperture, significantly depends on the condition-encoding variables. The data from the aperture-opening phase also fit a

Full Text Available Abstract Reaching hard-to-reach and high-risk injecting drug users (IDUs is one of the most important challenges for contemporary needle syringe programs (NSPs. The aim of this review is to examine, based upon the available international experience, the effectiveness of syringe vending machines and mobile van/bus based NSPs in making services more accessible to these hard-to-reach and high-risk groups of IDUs. A literature search revealed 40 papers/reports, of which 18 were on dispensing machines (including vending and exchange machines and 22 on mobile vans. The findings demonstrate that syringe dispensing machines and mobile vans are promising modalities of NSPs, which can make services more accessible to the target group and in particular to the harder-to-reach and higher-risk groups of IDUs. Their anonymous and confidential approaches make services attractive, accessible and acceptable to these groups. These two outlets were found to be complementary to each other and to other modes of NSPs. Services through dispensing machines and mobile vans in strategically important sites are crucial elements in continuing efforts in reducing the spread of HIV and other blood borne viruses among IDUs.

Riparian Vegetation Mapping Along the Hanford Reach
International Nuclear Information System (INIS)
FOGWELL, T.W.
2003-01-01
During the biological survey and inventory of the Hanford Site conducted in the mid-1990s (1995 and 1996), preliminary surveys of the riparian vegetation were conducted along the Hanford Reach. These preliminary data were reported to The Nature Conservancy (TNC), but were not included in any TNC reports to DOE or stakeholders. During the latter part of FY2001, PNNL contracted with SEE Botanical, the parties that performed the original surveys in the mid 1990s, to complete the data summaries and mapping associated with the earlier survey data. Those data sets were delivered to PNNL and the riparian mapping by vegetation type for the Hanford Reach is being digitized during the first quarter of FY2002. These mapping efforts provide the information necessary to create subsequent spatial data layers to describe the riparian zone according to plant functional types (trees, shrubs, grasses, sedges, forbs). Quantification of the riparian zone by vegetation types is important to a number of DOE'S priority issues including modeling contaminant transport and uptake in the near-riverine environment and the determination of ecological risk. This work included the identification of vegetative zones along the Reach by changes in dominant plant species covering the shoreline from just to the north of the 300 Area to China Bar near Vernita. Dominant and indicator species included Agropyron dasytachyudA. smithii, Apocynum cannabinum, Aristida longiseta, Artemisia campestris ssp. borealis var scouleriana, Artemisa dracunculus, Artemisia lindleyana, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Coreopsis atkinsoniana.

Quantification of the riparian zone by vegetation types is important to a number of DOE'S priority issues including modeling contaminant transport and uptake in the near-riverine environment and the determination of ecological risk. This work included the identification of vegetative zones along the Reach by changes in dominant plant species covering the shoreline from just to the north of the 300 Area to China Bar near Vernita. Dominant and indicator species included Agropyron dasytachyudA. smithii, Apocynum cannabinum, Aristida longiseta, Artemisia campestris ssp. borealis var scouleriana, Artemisa dracunculus, Artemisia lindleyana, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Coreopsis atkinsoniana.

Cycling as a mode of transport for people over 30 years old on a mountainous town
Energy Technology Data Exchange (ETDEWEB)
Maciel, L.
2016-07-01
The relationship between active transportation and its role in health of population motivated the continuation of a pilot study evaluating the use of bicycles in a mountain town. The objective was to evaluate people over 30 years old, with different physical abilities, in a predefined route and check if the relief was impediment. The studied divided the riders into 2 groups: active and sedentary. It was performed a comparison of the physiological impact (heart rate, blood pressure) and a subjective perception (modified Borg's scale), ranking the degrees of difficulty during route stretches. The participants filled in a form before and after the course. Most sedentary participants, despite having greater difficulty and reaching higher heart rates on certain stretches, managed to make the trip. It suggests that the current technology of the bike allows people less physically conditioned to be able to use the bike in mountain cities. (Author)

People into Employment: supporting people with disabilities and carers into work.
Arksey, Hilary
2003-05-01
Carers and people with disabilities are two disadvantaged groups at risk of social exclusion. Work is an important route to social inclusion, but carers and people with disabilities are under-represented in the work force. The present paper reports key findings from a new study that evaluated People into Employment (PIE), a pilot employment project in the north-east of England designed to support people with disabilities, carers and former carers in gaining mainstream work. The study aimed to identify what clients, partner agencies and employers perceived to be PIE's most important services, its strengths and areas where there was scope for further development. The study collected quantitative and qualitative data at the mid-point and at the end of the project through two questionnaire surveys, and interviews with PIE clients, the project development officer, partner agencies and employers. Drawing on the 'pathway model', the findings show that PIE's interventions included mobilising, matching, mediating and supporting activities. Key ingredients in PIE's success include: tailor-made job-search activities and training; adjusting the pace at which people move towards sustained employment; recognising and responding to the differing needs of people with disabilities, carers and former carers; confidence boosting; accompanying clients to job interviews; good job matching; and ongoing practical and emotional support for both clients and employers. Rudimentary calculations suggest that the cost per job to the project is less than the cost per job for large national projects. Overall, these findings illustrate how access to employment via flexible job-search services geared up to the local labour market can successfully promote social inclusion for carers and people with disabilities.

Full Text Available Police policy documents often articulate strategies and approaches that police organizations want to implement in their efforts to break down barriers with minority groups. However, most police policy documents are written for police audiences and not for members of the public. Police policy documents serve as a reflection of the aspirations of the agency and not necessarily the practice of the officers. Differential policing has been a salient experience for members of transgender communities because, as individuals who express gender in ways that deviate from the norm, they have experienced numerous documented cases of police mismanaged practice. In Australia, achieving police reform in the area of policing of diverse community groups has been difficult as new initiatives implemented to educate police officers about diverse groups such as transgender communities are scarce. My study sought to analyze a police policy document to assess how one police agency’s policy aspires to shape police contact/experiences with transgender people and how this document might shape intergroup identity differences between transgender people and the police. It is argued that the policy document will negatively affect police perceptions of transgender people and may enhance adverse perceptions of intergroup difference between police and transgender people. I also argue that using this document to achieve police reform in the area of policing of transgender people will be problematic as the policy document lacks substantial procedural guidelines regarding interaction with transgender people and may not favorably constrain discretionary police power.

Background An international review of the Cambodian Expanded Programme on Immunization (EPI) in 2010 and other data show that despite immunization coverage increases and vaccine preventable diseases incidence reductions, inequities in access to immunization services exist. Utilizing immunization and health systems literature, analysis of global health databases and the EPI review findings, this paper examines the characteristics of immunization access and outcome inequities, and describes proposed longer-term strategic and operational responses to these problems. Findings The national programme has evolved from earlier central and provincial level planning to strengthening routine immunization coverage through the District level ‘Reaching Every District Strategy’. However, despite remarkable improvements, the review found over 20% of children surveyed were not fully immunized, primarily from communities where inequities of both access and impact persist. These inequities relate mainly to socio-economic exposures including wealth and education level, population mobility and ethnicity. To address these problems, a shift in strategic and operational response is proposed that will include (a) a re-focus of planning on facility level to detect disadvantaged communities, (b) establishment of monitoring systems to provide detailed information on community access and utilization, (c) development of communication strategies and health networks that enable providers to adjust service delivery according to the needs of vulnerable populations, and (d) securing financial, management and political commitment for ‘reaching every community’. Conclusions For Cambodia to achieve its immunization equity objectives and disease reduction goals, a shift of emphasis to health centre and community is needed. This approach will maximize the benefits of new vaccine introduction in the coming ‘Decade of Vaccines’, plus potentially extend the reach of other life-saving maternal

[Giving up life in the labyrinth].
Portera Sánchez, A
2001-01-01
A brief historic survey of the labyrinth, from prehistoric images carved in stone, to gardens, Renaissance drawings and architectonic constructions will presented. The metaphor of the labyrinths, which began with Theseus killing the Minotaur with the help of Ariadne, can be applied to all: scientific investigation, artistic creation, wickedness, theology ... to life. In these eculiar and chaotic designs, structural simplicity and functional complexity coincide and therefore may produce repeated erroneous decisions. To wander successfully through these labyrinths, caution and repeated decision-makings are required to enable the traveller to reach the desired and elusive center. In each instant, decisions are made in our mind as a consequence of complex cerebral systems, activated by stimuli which originate in the intimate regions of the mind, the most complex labyrinth of all. These types of mental labyrinths are immaterial, without paths or walks, where each successive decision made facing multiple bifurcations, causes the mental traveller to advance until reaching the center. This center deceptively becomes the entrance to another of the innumerable and unknown mental labyrinths that the intimate life proposes.

Implementation of digital interventions for sexual health for young people
Directory of Open Access Journals (Sweden)
Sue Mann
2015-10-01
We conducted a scoping review of evidence on digital interventions for sexual health promotion for young people aged 13 to 24 years in the UK, defining sexual health in holistic terms, to include physical, emotional, mental and social well-being in relation to sexuality. Interactive digital interventions (IDI are defined as digital media programmes that provide sexual health information and tailored decision support, behaviour-change support, and/or emotional support for sexual health issues. We conducted a thorough review of literature to locate and synthesise available evidence on digital interventions for sexual health spanning the last ten years, integrating the findings with the views of key informants (young people, parents, and experts in digital media/sexual health. Results and conclusions There were few studies that assess the factors related to successful implementation of sexual health promotion IDIs. Potential barriers and facilitators to implementation of IDI should be addressed at the very beginning of an intervention development process. Engaging with sexual health promotion interventions online allows private and convenient access as well as potentially reaching populations who engage less frequently with mainstream services. However, it is difficult to ensure that users will find the intervention, or engage for long enough for them to be effective. The reach of online IDI could be enhanced by linking sexual health promotion interventions with existing digital systems such as STI self-test websites, or with trusted branded websites or popular social networking sites. Offering interventions in static settings such as the clinic or classroom encourages engagement and enables interventions to be delivered with fidelity but potentially at the expense of the privacy and convenience offered by online interventions. Using the knowledge of local staff is vital for both successful intervention development and successful implementation. An effective

The processing of visual and auditory information for reaching movements.
Glazebrook, Cheryl M; Welsh, Timothy N; Tremblay, Luc
2016-09-01
Presenting target and non-target information in different modalities influences target localization if the non-target is within the spatiotemporal limits of perceptual integration. When using auditory and visual stimuli, the influence of a visual non-target on auditory target localization is greater than the reverse. It is not known, however, whether or how such perceptual effects extend to goal-directed behaviours. To gain insight into how audio-visual stimuli are integrated for motor tasks, the kinematics of reaching movements towards visual or auditory targets with or without a non-target in the other modality were examined. When present, the simultaneously presented non-target could be spatially coincident, to the left, or to the right of the target. Results revealed that auditory non-targets did not influence reaching trajectories towards a visual target, whereas visual non-targets influenced trajectories towards an auditory target. Interestingly, the biases induced by visual non-targets were present early in the trajectory and persisted until movement end. Subsequent experimentation indicated that the magnitude of the biases was equivalent whether participants performed a perceptual or motor task, whereas variability was greater for the motor versus the perceptual tasks. We propose that visually induced trajectory biases were driven by the perceived mislocation of the auditory target, which in turn affected both the movement plan and subsequent control of the movement. Such findings provide further evidence of the dominant role visual information processing plays in encoding spatial locations as well as planning and executing reaching action, even when reaching towards auditory targets.

Restoring Maximum Vertical Browsing Reach in Sauropod Dinosaurs.
Paul, Gregory S
2017-10-01
The ongoing controversy centered on neck posture and function in sauropod dinosaurs is misplaced for a number of reasons. Because of an absence of pertinent data it is not possible to accurately restore the posture and range of motion in long necked fossil animals, only gross approximations are possible. The existence of a single "neutral posture" in animals with long, slender necks may not exist, and its relationship to feeding habits is weak. Restorations of neutral osteological neck posture based on seemingly detailed diagrams of cervical articulations are not reliable because the pictures are not sufficiently accurate due to a combination of illustration errors, and distortion of the fossil cervicals. This is all the more true because fossil cervical series lack the critical inter-centra cartilage. Maximum vertical reach is more readily restorable and biologically informative for long necked herbivores. Modest extension of 10° between each caudal cervical allowed high shouldered sauropods to raise the cranial portion of their necks to vertical postures that allowed them to reach floral resources far higher than seen in the tallest mammals. This hypothesis is supported by the dorsally extended articulation of the only known co-fused sauropod cervicals. Many sauropods appear to have been well adapted for rearing in order to boost vertical reach, some possessed retroverted pelves that may have allowed them to walk slowly while bipedal. A combination of improved high browsing abilities and sexual selection probably explains the unusually long necks of tall ungulates and super tall sauropods.

Motivated mind perception: treating pets as people and people as animals.
Epley, Nicholas; Schroeder, Juliana; Waytz, Adam
2013-01-01
Human beings have a sophisticated ability to reason about the minds of others, often referred to as using one's theory of mind or mentalizing. Just like any other cognitive ability, people engage in reasoning about other minds when it seems useful for achieving particular goals, but this ability remains disengaged otherwise. We suggest that understanding the factors that engage our ability to reason about the minds of others helps to explain anthropomorphism: cases in which people attribute minds to a wide range of nonhuman agents, including animals, mechanical and technological objects, and supernatural entities such as God. We suggest that engagement is guided by two basic motivations: (1) the motivation to explain and predict others' actions, and (2) the motivation to connect socially with others. When present, these motivational forces can lead people to attribute minds to almost any agent. When absent, the likelihood of attributing a mind to others, even other human beings, decreases. We suggest that understanding the factors that engage our theory of mind can help to explain the inverse process of dehumanization, and also why people might be indifferent to other people even when connecting to them would improve their momentary wellbeing.

This article analyzes the epidemiological situation of tuberculosis in the state of Rio Grande do Sul, emphasizing the indigenous population. The data are based on the Information System of Grievance Notification (Sinan) between 2003 and 2012. The notified cases of tuberculosis were analyzed according to age, sex, zone of residence, input type, means of diagnosis, clinical form, anti-HIV exam, medical care, supervised treatment (in Portuguese, TDO), closure, and race. The highest incidence rates in the period were among Afro-Brazilians, yellow, and indigenous peoples. The cases affected mainly adult men living in urban areas. Indigenous peoples showed the highest rates of notifications among people aged less than 10 years (12%). In the sputum test, missing information and not-performed exams reached more than 50.0% in all periods and groups. The cure was more prevalent among white people (66.2%); indigenous, brown, and Afro-Brazilian people presented the lowest cure rates: 59.4, 58.4, and 60%, respectively. Tuberculosis is one of the biggest problems in Rio Grande do Sul. The actions of diagnosis, clinical form, and treatment of the cases have not been implemented as proposed. The indigenous peoples' situation is similar and diverse at the same time in comparison with other peoples from different areas of Brazil. Nevertheless, it is unfavorable on a balanced evaluation of the whole scenario. Furthermore, the discrepancies among races are evident: the indigenous and Afro-Brazilian peoples fill the spread sheet, in general terms, on the worst situation, whereas the white people fill the data with the best health situation.

Vestibular feedback maintains reaching accuracy during body movement
Reynolds, Raymond F.
2016-01-01
Key points Reaching movements can be perturbed by vestibular input, but the function of this response is unclear.Here, we applied galvanic vestibular stimulation concurrently with real body movement while subjects maintained arm position either fixed in space or fixed with respect to their body.During the fixed‐in‐space conditions, galvanic vestibular stimulation caused large changes in arm trajectory consistent with a compensatory response to maintain upper‐limb accuracy in the face of body movement.Galvanic vestibular stimulation responses were absent during the body‐fixed task, demonstrating task dependency in vestibular control of the upper limb.The results suggest that the function of vestibular‐evoked arm movements is to maintain the accuracy of the upper limb during unpredictable body movement, but only when reaching in an earth‐fixed reference frame. Abstract When using our arms to interact with the world, unintended body motion can introduce movement error. A mechanism that could detect and compensate for such motion would be beneficial. Observations of arm movements evoked by vestibular stimulation provide some support for this mechanism. However, the physiological function underlying these artificially evoked movements is unclear from previous research. For such a mechanism to be functional, it should operate only when the arm is being controlled in an earth‐fixed rather than a body‐fixed reference frame. In the latter case, compensation would be unnecessary and even deleterious. To test this hypothesis, subjects were gently rotated in a chair while being asked to maintain their outstretched arm pointing towards either earth‐fixed or body‐fixed memorized targets. Galvanic vestibular stimulation was applied concurrently during rotation to isolate the influence of vestibular input, uncontaminated by inertial factors. During the earth‐fixed task, galvanic vestibular stimulation produced large polarity‐dependent corrections in arm

Exploring REACH as a potential data source for characterizing ecotoxicity in life cycle assessment.
Müller, Nienke; de Zwart, Dick; Hauschild, Michael; Kijko, Gaël; Fantke, Peter
2017-02-01
Toxicity models in life cycle impact assessment (LCIA) currently only characterize a small fraction of marketed substances, mostly because of limitations in the underlying ecotoxicity data. One approach to improve the current data situation in LCIA is to identify new data sources, such as the European Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) database. The present study explored REACH as a potential data source for LCIA based on matching reported ecotoxicity data for substances that are currently also included in the United Nations Environment Programme/Society for Environmental Toxicology and Chemistry (UNEP/SETAC) scientific consensus model USEtox for characterizing toxicity impacts. Data are evaluated with respect to number of data points, reported reliability, and test duration, and are compared with data listed in USEtox at the level of hazardous concentration for 50% of the covered species per substance. The results emphasize differences between data available via REACH and in USEtox. The comparison of ecotoxicity data from REACH and USEtox shows potential for using REACH ecotoxicity data in LCIA toxicity characterization, but also highlights issues related to compliance of submitted data with REACH requirements as well as different assumptions underlying regulatory risk assessment under REACH versus data needed for LCIA. Thus, further research is required to address data quality, pre-processing, and applicability, before considering data submitted under REACH as a data source for use in LCIA, and also to explore additionally available data sources, published studies, and reports.

Full Text Available In this work, an innovative robotic solution for human care and assistance is presented. Our main objective is to develop a new concept of portable robot able to support the elderly and those people with different levels of disability during the execution of daily tasks, such as washing their face or hands, brushing their teeth, combing their hair, eating, drinking, and bringing objects closer, among others. Our prototype, ASIBOT, is a five degrees of freedom (DOF self-contained manipulator that includes the control system and electronic equipment on board. The main advantages of the robot are its light weight, about 11 kg for a 1.3 m reach, its autonomy, and its ability to move between different points (docking stations of the room or from the environment to a wheelchair and vice versa, which facilitates its supportive functions. The functional evaluation of ASIBOT is addressed in this paper. For this purpose the robotic arm is tested in different experiments with disabled people, gathering and discussing the results according to a methodology that allows us to assess users' satisfaction.

Radioactivity of people in Finland after the Chernobyl accident in 1986
International Nuclear Information System (INIS)
Rahola, T.; Suomela, M.; Illukka, E.; Puhakainen, M.; Pusa, S.
1987-06-01
After the reactor accident at Chernobyl on April 26, 1986 radioactive fallout was carried by air currents to most parts of Europe. The radioactive air currents reached Finland on April 27. Immediately after the arrival of such air in Finland, contamination of people by radioactive nuclides began via inhalation of this air. The ingestion route become important later, when radionuclides were transported via different foodchains to man. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the Chernobyl accident, whole-body counting measurements were performed. The results of whole-body counting of six different groups of Finnish people measured during 1986 after the accident at Chernobyl are reported. Three were reference groups measured routinely once or twice annually, two groups were comprised of workers at nuclear power stations and one group consisted of 262 persons not belonging to any other group. The total number of whole-body counting measurements of persons in these groups in 1986 from the end of April to the end of December was 624. In April and May small amounts of 131 I were detected in the thyroid. In June the first signs of 134 Cs in the body were noticed. At the end of 1986 the mean 134 Cs body burden for women and men in the Helsinki reference group was 730 Bq. The mean 137 Cs body burden in women and men increased from 150 Bq in June to 1500 Bq in December. The differences in the deposition levels in the five fallout regions into which Finland was divided were reflected in the activity levels of the measured people. The weighted annual mean body burden for people in Finland at the end of 1986 was 370 Bq 134 Cs and 820 Bq 137 Cs. The maximum body burdens of 134 Cs and 137 Cs found in Finns in 1986 were 6300 Bq and 13000 Bq, respectively. The mean internal committed effective dose equivalent 0.06 mSv from 134 Cs and 137 Cs in the body of Finnish people in 1986 was calculated using the whole

Reaching people with energy conservation information: four statewide residential case studies
Energy Technology Data Exchange (ETDEWEB)
Peelle, E.; Braid, R.B.; Jones, D.W.; Reed, J.H.
1983-09-01
Four state residential energy conservation programs are reviewed in terms of their origins, evolutions, purposes and goals, administration, organization, and outcomes. The four programs chosen were selected from among 30 nominated by state energy offices and regional Department of Energy personnel as being illustrative in terms of organization and/or outcomes. While intended primarily for state-level program managers and staff, the profiles of programs, conclusions, and recommendations should be useful to anyone interested in developing viable, action-oriented conservation programs. The four case studies included Oregon's Master Conserver program, Oklahoma's energy education project for low-income and elderly families, Virginia's workshops for heating dealers service and contractors, and Maine's three energy education projects - the Energy Bus, Energy Conservation Month, and the Home Energy Check-up. All four programs utilized Energy Extension Service (EES) funds from the federal government, and three were directly managed through the state EES organization. The findings of the study indicate that these programs (1) had flexibility to experiment, iterate, and reorganize as a result of their initial experiences, (2) made extensive use of networking to involve local groups in program delivery, (3) employed a large variety of delivery methods, and (4) made substantial efforts to tailor literature and handouts to the target audiences.

Characterizing and predicting submovements during human three-dimensional arm reaches.
Directory of Open Access Journals (Sweden)
James Y Liao
Full Text Available We have demonstrated that 3D target-oriented human arm reaches can be represented as linear combinations of discrete submovements, where the submovements are a set of minimum-jerk basis functions for the reaches. We have also demonstrated the ability of deterministic feed-forward Artificial Neural Networks (ANNs to predict the parameters of the submovements. ANNs were trained using kinematic data obtained experimentally from five human participants making target-directed movements that were decomposed offline into minimum-jerk submovements using an optimization algorithm. Under cross-validation, the ANNs were able to accurately predict the parameters (initiation-time, amplitude, and duration of the individual submovements. We also demonstrated that the ANNs can together form a closed-loop model of human reaching capable of predicting 3D trajectories with VAF >95.9% and RMSE ≤4.32 cm relative to the actual recorded trajectories. This closed-loop model is a step towards a practical arm trajectory generator based on submovements, and should be useful for the development of future arm prosthetic devices that are controlled by brain computer interfaces or other user interfaces.

Partnerships: The Key to Sustainability and Reach for E/PO
Eisenhamer, Bonnie; McCallister, D.; Ryer, H.
2013-06-01
The Space Telescope Science Institute (STScI) is the home institution for the E/PO activities of the Hubble and future James Webb space telescopes. Over time, STScI’s Office of Public Outreach has established the infrastructure needed for an E/PO program that reaches various audiences at the local, regional, and national levels. Partnerships are a critical element of this infrastructure, and sustainability of our E/PO program is ensured through our ongoing partnerships with organizations and institutions with staying power and reach. We have learned from past efforts that strategic partnerships can foster innovation, support diversity initiatives, and increase impact in a cost-effective way while providing target audiences with greater access to NASA SMD science and resources. Partnerships are utilized to field-test educational products and programs, disseminate materials and initiatives, and support professional development activities. Partners are selected based upon specific criteria such as potential for reach, the percentage of underrepresented educators and students served, complementary program goals, and willingness to collect and share evaluation data and results with us. This poster will highlight examples and benefits of strategic partnerships over time.

Phenomena and characteristics of barrier river reaches in the middle and lower Yangtze River, China
You, Xingying; Tang, Jinwu
2017-06-01
Alluvial river self-adjustment describes the mechanism whereby a river that was originally in an equilibrium state of sediment transport encounters some disturbance that destroys the balance and results in responses such as riverbed deformation. A systematic study of historical and recent aerial photographs and topographic maps in the Middle and Lower Reaches of the Yangtze River (MLYR) shows that river self-adjustment has the distinguishing feature of transferring from upstream to downstream, which may affect flood safety, waterway morphology, bank stability, and aquatic environmental safety over relatively long reaches downstream. As a result, it is necessary to take measures to control or block this transfer. Using the relationship of the occurrence time of channel adjustments between the upstream and downstream, 34 single-thread river reaches in the MLYR were classified into four types: corresponding, basically corresponding, basically not corresponding, not corresponding. The latter two types, because of their ability to prevent upstream channel adjustment from transferring downstream, are called barrier river reaches in this study. Statistics indicate that barrier river reaches are generally single thread and slightly curved, with a narrow and deep cross-sectional morphology, and without flow deflecting nodes in the upper and middle parts of reaches. Moreover, in the MLYR, barrier river reaches have a hydrogeometric coefficient of {}1.2‱, a silty clay content of the concave bank {>}{9.5}%, and a median diameter of the bed sediment {>}{0.158} mm. The barrier river reach mechanism lies in that can effectively centralise the planimetric position of the main stream from different upstream directions, meaning that no matter how the upper channel adjusts, the main stream shows little change, providing relatively stable inflow conditions for the lower reaches. Regarding river regulation, it is necessary to optimise the benefits of barrier river reaches; long river

Home care service demands are increasing in Japan; this necessitates improved service allocation. This study examined the relationship between home visit nursing (HVN) service use and the proportion of elderly people living within 10 min' travel of HVN agencies. The population of elderly people living within reach of HVN agencies for each of 17 municipalities in one low-density prefecture was calculated using public data and geographic information systems. Multilevel logistic analysis for 2641 elderly people was conducted using medical and long-term care insurance claims data from October 2010 to examine the association between the proportion of elderly people reachable by HVNs and service usage in 13 municipalities. Municipality variables included HVN agency allocation appropriateness. Individual variables included HVN usage and demographic variables. The reachable proportion of the elderly population ranged from 0.0 to 90.2% in the examined municipalities. The reachable proportion of the elderly population was significantly positively correlated with HVN use (odds ratio: 1.938; confidence interval: 1.265-2.967). Residents living in municipalities with a lower reachable proportion of the elderly population are less likely to use HVN services. Public health interventions should increase the reachable proportion of the elderly population in order to improve HVN service use.

Registered Nurses working together with family members of older people.
Weman, Karin; Fagerberg, Ingegerd
2006-03-01
The aim of the study was to reach a more profound understanding, through looking at nurses' working situation, of those factors that influence how nurses are able to work together with family members of older people living in nursing homes or similar facilities. Working with the care of older people as a Registered Nurse provides a varied job with many challenges. Nurses have to co-operate with family members of those in community health care. Co-operation is important and necessary for all involved. Nurses working in elder care in a geographically defined area received a questionnaire with three open-ended questions, on the difficulties and/or problems involved with working together with family members, and the positive or negative aspects of this co-operation. Analysis was carried out using the latent content analysis method. Three themes, problems within the system, interaction with families and caring in nursing work, are presented with categories and their subcategories. The nurses wanted their superior to be a nurse so that their working situation would be better understood. Appreciation from their superior and family members was also a very important part of their work as nurses in community health care. The frequent changes and the lack of time in the work of elder care often put nurses under considerable psychological pressure. For the most part family members are a resource for the elder, but sometimes they will avoid contact, which will make co-operating difficult. Registered Nurses and family members are dependent on each other in their care of the elder. Relevance to clinical practice. More attention should be paid to the working situation of Registered Nurses in community health care, and their ability to work together with family members of older people.

What's different about older people.
Crome, Peter
2003-10-01
Older people can be regarded as a marginalised group within society from a number of perspectives including that of health. When it comes to the use of medication older people have suffered from a double whammy. Not only are they more at risk from the adverse effects of drugs but also their involvement in clinical trials has been limited so that rational prescribing both to maximise benefit and to reduce risk has been problematic. Their special problems have been recognised formerly by the Department of Health in its NSF for Older People [National Service Framework for Older People. Department of Health, London (2001a)], [Medicines and Older People. Implementing medicines-related aspects of the NSF for Older People. Department of Health (2001b)]. Early studies focussed on compliance, the avoidance of poly-pharmacy and the high prevalence of adverse effects of drugs and the reasons for this. Studies in long-stay patients showed dramatic differences in pharmacokinetics between such older people and young healthy volunteers. Initially such differences were ascribed to age alone and the overall message became "start low and go slow". Studies in healthy older people then revealed that age differences in drug metabolism were, as a rule, not so marked although clearance of renally excreted drugs was reduced in line with the age associated decline in renal function. Including older people in clinical trials poses challenges. Many traditional trialists do not have ready access to older people, co-morbidity and poly-pharmacy are common and most people feel reluctant to ask older people to take part in complex and potentially hazardous trials. Concern about compliance is unwarranted. Adverse events may be more serious. Thus in a younger patient postural hypotension may make a subject unsteady but in an older subject the unsteadiness may lead to a fall, the fall to a fracture, and the fracture to poor recovery. The choice of end-points is crucial. Although reduction of

Dialectical behavior therapy (DBT) is an evidence-based treatment for borderline personality disorder. The DBT Intensive Training™ is widely used to train community clinicians to deliver DBT, but little is known about its effectiveness. This study prospectively evaluated predictors of adoption and reach of DBT among 52 community teams (212 clinicians) after DBT Intensive Training™. Pre-post training questionnaires were completed by trainees and a follow-up survey by team leaders approximately 8 months later. Overall, 75% of teams adopted all DBT modes and delivered DBT to an average of 118 clients. Lower training and program needs, fewer bachelor's-level clinicians, and greater prior DBT experience predicted adoption of more DBT modes. More prior DBT experience, smaller team size, more negative team functioning, and staff with lower job satisfaction, growth, efficacy, and influence predicted greater DBT reach. DBT Intensive Training™ appears effective in promoting DBT adoption and reach in routine clinical practice settings.

Science communication is at an all-time high but public faith in expertise is low. However, within this climate of suspicion, research scientists remain a publicly trusted expert group. While there is both academic and public appetite for Public Engagement with Research (PER), there are barriers to reaching a wide range of publics. Attempts to connect the public with research often end up targeting the `already engaged'; the hard-to-reach remain just that. Engaging scientific curiosity in a wider demographic is crucial to promote scientific curiosity, itself known to profoundly counter the politically motivated reasoning that threatens informed debate around contemporary environmental issues. This requires the creation of opportunities for the public to engage with research in places in which they feel they belong. We report here on an 8 month pilot of a science centre model for PER. Oriel Science (www.orielscience.co.uk) is a research-led science exhibition in Swansea city centre delivering Swansea University's PER and run by academics and student ambassadors. Oriel Science (Oriel is Gallery in Welsh) received 16,000 visitors in 8 months, 40% of whom had no previous interaction with the university or its research and >40% of whom came from socio-economically deprived areas. We report on the public engagement leadership we enabled, working with 18 research groups over 8 months and our achievements in giving a broad range of publics the most direct access to participate in contemporary science.

Role of limb and target vision in the online control of memory-guided reaches.
Heath, Matthew
2005-07-01
This investigation tested the proposal that a "highly accurate" and temporally unstable stored target representation is available to the motor system for the online control of memory-guided reaches. Participants reached to a target that was: (a) visible during the response, (b) extinguished at movement onset, and (c) occluded for 0, 500, 1,500 and 2,500 ms in advance of response cueing. Additionally, trials were performed with (i.e., limb visible) and without (i.e., limb occluded) vision of the reaching limb. Results showed that limb occluded trials undershot the target location in each target condition, and were characterized by a primarily offline mode of control. In contrast, limb visible trials showed a consistent level of endpoint accuracy for each target condition and elicited more online reaching corrections than limb occluded trials. It is therefore proposed that a reasonably accurate and temporally stable stored target representation can be combined with vision of the moving limb for the online control of memory-guided reaches.

The objective was to estimate the reliability and criterion-related validity of the Jump-and-Reach Test for the assessment of squat, countermovement, and drop jump performance of 32 male Brazilian professional volleyball players. Performance of squat, countermovement, and drop jumps with different dropping heights was assessed on the Jump-and-Reach Test and the measurement of flight time, then compared across different jump trials. The very high reliability coefficients of both assessment methods and the lower correlation coefficients between scores on the assessments indicate a very high consistency of each method but only moderate covariation, which means that they measure partly different items. As a consequence, the Jump-and-Reach Test has good ecological validity in situations when reaching height during the flight phase is critical for performance (e.g., basketball and volleyball) but only limited accuracy for the assessment of vertical impulse production with different jump techniques and conditions.

Full Text Available The purpose of this study was using an accelerometer to access the kinematics of reach-to-grasp movements in subjects with hemiparesis. Eight subjects (59.4 ± 6.9 years old with chronic hemiparesis (50.9 ± 25.8 months post-stroke participated in this study. Kinematic assessment was performed using a triaxial accelerometer (EMG Systems, Brazil attached to the subjects' forearm. Ten reach-to-grasp movements of grabbing a 500ml-size bottle were performed by the subjects with the paretic and the non-paretic upper limbs (ULs. The following space-temporal variables were calculated and used to compare the paretic and non-paretic ULs: movement time (MT, time to reach the peak velocity, absolute and relative (TPV and TPV%MT, relative deceleration duration (DEC%MT, time to peak acceleration (TPA and peak hand acceleration (PA. Movements were slower in the paretic UL with increased MT, TPA and DEC. The accelerometer allowed to identify of changes in reaching-to-grasp movements of subjects with hemiparesis. When complex systems are not available, accelerometers can be an alternative to measure UL movements.

An increasing number of people with intellectual disability (ID) are reaching older ages today although they experience more health problems than the older population without ID. Leaders in intellectual disability services can greatly influence the conditions for a healthy ageing, and the aim of the present study was to explore healthy ageing in this group from the perspective of the leaders. Interviews with 20 leaders were subjected to qualitative content analysis. The findings gave rise to the overall theme ageing in dependence, which emerged from the following six categories: Supporting self-determination; Inaccessible activities after retirement; Signs of decline; Increased and specific needs for support and care; A non-question of gender; Aspects concerning the end of life and death. A prerequisite for healthy ageing in the case of people with ID is, according to the leaders, that they can live the life according to their preferences and make independent choices whilst at the same time receiving adequate support. With the shrinking of their social network after retirement, they become increasingly dependent on staff and leaders in the group home, who need to know what healthy ageing implies.

Executive function is the key area of cognitive impairment in Parkinson's disease. This study investigated how cognitive difficulties impact on everyday life of people with Parkinson's disease and their carers, and whether they explicitly mention executive-type difficulties. Semistructured interviews with 11 people with Parkinson's disease and six carers were analyzed thematically. People with Parkinson's disease performed within the normal range on cognitive screening tests, but all had abnormal scores on tests of executive function. Despite relatively mild executive deficits and no global cognitive impairment, participants described executive-type difficulties as well as a range of problems in other cognitive domains, such as memory, processing speed and apathy. Cognitive difficulties had a far-reaching impact on everyday life and their significance depended on personal circumstances, such as the level of responsibilities of the person with Parkinson's disease and the extent of available support. By presenting subjective accounts of living with Parkinson's disease and cognitive difficulties, this study improves our understanding of how the observed level of cognitive impairment translates into everyday functioning. The study results have implications for recognizing cognitive difficulties and for planning support for people with Parkinson's disease and their families, and can help identify ways of promoting effective self-management. Implications for rehabilitation Treatment of Parkinson's disease tends to focus on the movement disorder, meaning that cognitive difficulties and their impact can be overlooked. Participants in this study had only relatively mild executive deficits but described a range of cognitive problems, including executive-type difficulties. Cognitive difficulties have an emotional impact and can cause a range of challenges in everyday life, adding to the burden of physical symptoms of Parkinson's disease. Results of this study provide insights

Trauma, in the form of pressure and/or friction from footwear, is a common cause of foot ulceration in people with diabetes. These practical recommendations regarding the provision of footwear for people with diabetes were agreed upon following review of existing position statements and clinical guidelines. The aim of this process was not to re-invent existing guidelines but to provide practical guidance for health professionals on how they can best deliver these recommendations within the Australian health system. Where information was lacking or inconsistent, a consensus was reached following discussion by all authors. Appropriately prescribed footwear, used alone or in conjunction with custom-made foot orthoses, can reduce pedal pressures and reduce the risk of foot ulceration. It is important for all health professionals involved in the care of people with diabetes to both assess and make recommendations on the footwear needs of their clients or to refer to health professionals with such skills and knowledge. Individuals with more complex footwear needs (for example those who require custom-made medical grade footwear and orthoses) should be referred to health professionals with experience in the prescription of these modalities and who are able to provide appropriate and timely follow-up. Where financial disadvantage is a barrier to individuals acquiring appropriate footwear, health care professionals should be aware of state and territory based equipment funding schemes that can provide financial assistance. Aboriginal and Torres Strait Islanders and people living in rural and remote areas are likely to have limited access to a broad range of footwear. Provision of appropriate footwear to people with diabetes in these communities needs be addressed as part of a comprehensive national strategy to reduce the burden of diabetes and its complications on the health system.

With a passing of time, sport evolved to integrated part of rehabilitation as an element of improvement. Moreover, he became as a tool to improve the social integration of people which finished the treatment or/and have deficits. We can notice the huge sport development of people with disabilities, which was initiated by Sir Ludwig Guttmann’s who claimed that view of sport is equal for people with disabilities and able-bodied people. The quality of physical activity of people with disabilities is indicated by motor preparation, training and sport (wellness, nutritionist, sport and exercise psychologist which currently is all the same except individual approach to particular dysfunction of the person with disability.

Transcranial magnetic stimulation and preparation of visually-guided reaching movements
Directory of Open Access Journals (Sweden)
Pierpaolo eBusan
2012-08-01
Full Text Available To better define the neural networks related to preparation of reaching, we applied transcranial magnetic stimulation (TMS to the lateral parietal and frontal cortex. TMS did not evoke effects closely related to preparation of reaching, suggesting that neural networks already identified by our group are not larger than previously thought. We also replicated previous TMS/EEG data by applying TMS to the parietal cortex: new analyses were performed to better support reliability of already reported findings (Zanon et al., 2010; Brain Topography 22, 307-317. We showed the existence of neural circuits ranging from posterior to frontal regions of the brain after the stimulation of parietal cortex, supporting the idea of strong connections among these areas and suggesting their possible temporal dynamic. Connection with ventral stream was confirmed.The present work helps to define those areas which are involved in preparation of natural reaching in humans. They correspond to parieto-occipital, parietal and premotor medial regions of the left hemisphere, i.e. the contralateral one with respect to the moving hand, as suggested by previous studies. Behavioral data support the existence of a discrete stream involved in reaching. Besides the serial flow of activation from posterior to anterior direction, a parallel elaboration of information among parietal and premotor areas seems also to exist. Present cortico-cortical interactions (TMS/EEG experiment show propagation of activity to frontal, temporal, parietal and more posterior regions, exhibiting distributed communication among various areas in the brain.The neural system highlighted by TMS/EEG experiments is wider with respect to the one disclosed by the TMS behavioral approach. Further studies are needed to unravel this paucity of overlap. Moreover, the understanding of these mechanisms is crucial for the comprehension of response inhibition and changes in prepared actions, which are common behaviors in

The upcoming Surface Water and Ocean Topography (SWOT) mission will measure water surface heights and widths for rivers wider than 100 m. At its native resolution, SWOT height errors are expected to be on the order of meters, which prevent the calculation of water surface slopes and the use of slope-dependent discharge equations. To mitigate height and width errors, the high-resolution measurements will be grouped into reaches (˜5 to 15 km), where slope and discharge are estimated. We describe three automated river segmentation strategies for defining optimum reaches for discharge estimation: (1) arbitrary lengths, (2) identification of hydraulic controls, and (3) sinuosity. We test our methodologies on 9 and 14 simulated SWOT overpasses over the Sacramento and the Po Rivers, respectively, which we compare against hydraulic models of each river. Our results show that generally, height, width, and slope errors decrease with increasing reach length. However, the hydraulic controls and the sinuosity methods led to better slopes and often height errors that were either smaller or comparable to those of arbitrary reaches of compatible sizes. Estimated discharge errors caused by the propagation of height, width, and slope errors through the discharge equation were often smaller for sinuosity (on average 8.5% for the Sacramento and 6.9% for the Po) and hydraulic control (Sacramento: 7.3% and Po: 5.9%) reaches than for arbitrary reaches of comparable lengths (Sacramento: 8.6% and Po: 7.8%). This analysis suggests that reach definition methods that preserve the hydraulic properties of the river network may lead to better discharge estimates.

Clinical measures of balance in people with type two diabetes: A systematic literature review.
Dixon, C J; Knight, T; Binns, E; Ihaka, B; O'Brien, D
2017-10-01
Approximately 422 million people have diabetes mellitus worldwide, with the majority diagnosed with type 2 diabetes mellitus (T2DM). The complications of diabetes mellitus include diabetic peripheral neuropathy (DPN) and retinopathy, both of which can lead to balance impairments. Balance assessment is therefore an integral component of the clinical assessment of a person with T2DM. Although there are a variety of balance measures available, it is uncertain which measures are the most appropriate for this population. Therefore, the aim of this study was to conduct a systematic review on clinical balance measures used with people with T2DM and DPN. Databases searched included: CINAHL plus, MEDLINE, SPORTDiscus, Dentistry and Oral Sciences source, and SCOPUS. Key terms, inclusion and exclusion criteria were used to identify appropriate studies. Identified studies were critiqued using the Downs and Black appraisal tool. Eight studies were included, these studies incorporated a total of ten different clinical balance measures. The balance measures identified included the Dynamic Balance Test, balance walk, tandem and unipedal stance, Functional Reach Test, Clinical Test of Sensory Interaction and Balance, Berg Balance Scale, Tinetti Performance-Oriented Mobility Assessment, Activity-Specific Balance Confidence Scale, Timed Up and Go test, and the Dynamic Gait Index. Numerous clinical balance measures were used for people with T2DM. However, the identified balance measures did not assess all of the systems of balance, and most had not been validated in a T2DM population. Therefore, future research is needed to identify the validity of a balance measure that assesses these systems in people with T2DM. Copyright © 2017 The Authors. Published by Elsevier B.V.

Measles supplementary immunization activities (SIAs) are vaccination campaigns that supplement routine vaccination programs with a recommended second dose opportunity to children of different ages regardless of their previous history of measles vaccination. They are conducted every 2-4 years and over a few weeks in many low- and middle-income countries. While SIAs have high vaccination coverage, it is unclear whether they reach the children who miss their routine measles vaccine dose. Determining who is reached by SIAs is vital to understanding their effectiveness, as well as measure progress towards measles control. We examined SIAs in low- and middle-income countries from 2000 to 2014 using data from the Demographic and Health Surveys. Conditional on a child's routine measles vaccination status, we examined whether children participated in the most recent measles SIA. The average proportion of zero-dose children (no previous routine measles vaccination defined as no vaccination date before the SIA) reached by SIAs across 14 countries was 66%, ranging from 28% in São Tomé and Príncipe to 91% in Nigeria. However, when also including all children with routine measles vaccination data, this proportion decreased to 12% and to 58% when imputing data for children with vaccination reported by the mother and vaccination marks on the vaccination card across countries. Overall, the proportions of zero-dose children reached by SIAs declined with increasing household wealth. Some countries appeared to reach a higher proportion of zero-dose children using SIAs than others, with proportions reached varying according to the definition of measles vaccination (e.g., vaccination dates on the vaccination card, vaccination marks on the vaccination card, and/or self-reported data). This suggests that some countries could improve their targeting of SIAs to children who miss other measles vaccine opportunities. Across all countries, SIAs played an important role in reaching

Full Text Available Today, the economic and financial crisis is brought to light and it is now clear that many people are directly impacted by this phenomenon. However, a lot of situations are obviously hidden and in particular those concerning over-indebted people. These people often find that it is difficult to express the hardship they are going through and keep silent because is more comfortable for them. The media also does not tackle this burning issue because the complexity of some situations complicates the message. Therefore, a giant gap has appeared leaving over-indebted people entrapped in their secret. Starting from this hypothesis, this article will examine the results of a research conducted on the over-indebted people (survey on written press, analysis of TV broadcasts, analysis of records related to person in debts and responses of people in debts and the secrets that this phenomenon involves.

In Hong Kong, the general view still follows the biomedical discourse to define aging. The government and leading gerontologists follow the prevailing representation of elderly and describe growing old as a process of becoming "frail, infirm, and vulnerable" (Fealy et al., 2012: 91). Discussions of demographic trends often focus on the drastic effects of an aging society on economic development. Our research indicates that Hong Kong's construction of aging is a product of its market-driven economy. Drawing from the life stories of eight participants born in the 1930s, we examine the meaning of aging and the formation of character in a specific historical context, adopting the life-course perspective. We wish to understand how larger movements in the social and political world shaped the experiences of the participants and the strategies they developed to maintain agency and control in life. The participants in our study struggled for survival through unprecedented political disasters and social turmoil in their youth. When they reached maturity in the 1960s and 1970s, they devoted themselves to bettering their lives and contributed to the economic boom of the city. We maintain that the biomedical model offers a reductive and unjust means of viewing the people in this cohort, who are often seen as a problem and a burden. Challenging the prevailing ageist attitude, we set the life stories of the participants against the dominant biomedical model of aging. Our work aims to establish a just description of the life experiences of Hong Kong people. Copyright © 2015 Elsevier Inc. All rights reserved.

The new European Union framework directive on waste is to be implemented during the year 2010. According to this directive, much of what today is regarded as waste will instead be assessed as by-products and in many cases fall under the new European union regulation REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals). REACH applies in conjunction with the new European Union regulation CLP (Classification, Labelling and Packaging of substances and mixtures). There are introductory periods for both of these regulations, and in the case of CLP this regards transition from the present and previous rules under the dangerous substances and dangerous preparations directives (DSD and DPD, respectively). Similarly, the new framework directive on waste supersedes the previous directive and some other statements. There is a connection between the directives of waste and the rules for classification and labelling in that the classification of waste (in the categories hazardous and non-hazardous) build on (but are not identical to) the rules for labelling. Similarly, the national Swedish rules for acceptance of recycled material (waste) for use in geotechnical constructions relate to the provisions in REACH on assessment of chemical safety in the both request that the risk be assessed to be small, and that the same or similar methodologies can be applied to verify this.

Tobacco use among lesbian, gay, bisexual, and transgender (LGBT) people is double the general population. Limited evidence suggests high smoking rates among intersex people. Lesbian, gay, bisexual, transgender, and intersex (LGBTI) people are a priority population in Australian health policy, particularly mental health and aging. Despite associations between smoking and noncommunicable diseases relevant to aging and mental health, LGBTI-targeted smoking cessation interventions in Australia have been limited to people living with HIV. Applying existing interventions to marginalized populations without modification and evaluation may fail and exacerbate inequities. To assess outcomes and characterize the populations served, cultural modifications, and behavior change techniques (BCTs) of interventions to reduce LGBTI smoking. We searched MEDLINE, six additional databases, and contacted authors to retrieve published and unpublished program evaluations. We retrieved 19 studies (3663 participants). None used control groups. Overall quit rate was 61.0% at the end of interventions and stabilized at 38.6% at 3-6 months. All studies included gay men, 13 included lesbians, 13 "LGBT," 12 bisexual people, five transgender people, and none included intersex people. Transgender people comprised 3% of participants. Of programs open to women, 27.8% of participants were women. Cultural modifications were used by 17 (89.5%) studies, commonly meeting in LGBT spaces, discussing social justice, and discussing LGBT-specific triggers. Common BCTs included providing normative information, boosting motivation/self-efficacy, relapse prevention, social support, action planning, and discussing consequences. Quit rates were high; using control groups would improve evaluation. Existing programs may fail to reach groups other than gay men. This review examines the evidence for LGBTI-targeted smoking cessation interventions. Populations within LGBTI are not proportionally represented in smoking

The objective of this study is to compare the balance and gait of 11 people with multiple sclerosis (MS) to 11 healthy controls and to investigate the immediate change after a single intervention based on the Bobath concept on these activities in the MS group. Balance was assessed by ground reaction forces (GRF) and centre of pressure movements during single limb standing (SLS), the Lateral Reach Test (LRT) and the Four Square Step Test (FSST). Gait was evaluated by GRF, ankle kinematics and spatiotemporal measures. Baseline measures in the MS group showed significantly greater vertical GRF variability (p = 0.008) during SLS reached less distance on the LRT (p = 0.001) and were slower completing the FSST (p Bobath concept delivered to the most impaired foot and ankle. After the intervention, the MS group had significant changes towards the control group values with reduced mediolateral (p = 0.002) and vertical (p = 0.016) GRF variability in the SLS task, faster FSST time (p = 0.006) and increased ankle PF during gait (p = 0.002). This study provides further evidence of balance and gait limitations in people with MS and indicates that a single treatment based on principles of the Bobath concept to the foot and ankle can result in immediate improvements in balance and ankle PF during gait in people with MS.

Adaptation to delayed force perturbations in reaching movements.
Directory of Open Access Journals (Sweden)
Noa Levy
Full Text Available Adaptation to deterministic force perturbations during reaching movements was extensively studied in the last few decades. Here, we use this methodology to explore the ability of the brain to adapt to a delayed velocity-dependent force field. Two groups of subjects preformed a standard reaching experiment under a velocity dependent force field. The force was either immediately proportional to the current velocity (Control or lagged it by 50 ms (Test. The results demonstrate clear adaptation to the delayed force perturbations. Deviations from a straight line during catch trials were shifted in time compared to post-adaptation to a non-delayed velocity dependent field (Control, indicating expectation to the delayed force field. Adaptation to force fields is considered to be a process in which the motor system predicts the forces to be expected based on the state that a limb will assume in response to motor commands. This study demonstrates for the first time that the temporal window of this prediction needs not to be fixed. This is relevant to the ability of the adaptive mechanisms to compensate for variability in the transmission of information across the sensory-motor system.

Evaluating Regime Change of Sediment Transport in the Jingjiang River Reach, Yangtze River, China
Directory of Open Access Journals (Sweden)
Li He
2018-03-01
Full Text Available The sediment regime in the Jingjiang river reach of the middle Yangtze River has been significantly changed from quasi-equilibrium to unsaturated since the impoundment of the Three Gorges Dam (TGD. Vertical profiles of suspended sediment concentration (SSC and sediment flux can be adopted to evaluate the sediment regime at the local and reach scale, respectively. However, the connection between the vertical concentration profiles and the hydrologic conditions of the sub-saturated channel has rarely been examined based on field data. Thus, vertical concentration data at three hydrological stations in the reach (Zhicheng, Shashi, and Jianli are collected. Analyses show that the near-bed concentration (within 10% of water depth from the riverbed may reach up to 15 times that of the vertical average concentration. By comparing the fractions of the suspended sediment and bed material before and after TGD operation, the geomorphic condition under which the distinct large near-bed concentrations occur have been examined. Based on daily discharge-sediment hydrographs, the reach scale sediment regime and availability of sediment sources are analyzed. In total, remarkable large near-bed concentrations may respond to the combination of wide grading suspended particles and bed material. Finally, several future challenges caused by the anomalous vertical concentration profiles in the unsaturated reach are discussed. This indicates that more detailed measurements or new measuring technologies may help us to provide accurate measurements, while a fractional dispersion equation may help us in describing. The present study aims to gain new insights into regime change of sediment suspension in the river reaches downstream of a very large reservoir.

The mangrove area has an important meaning in beach ecosystem, both from ecological and economical aspects. For this, the rehabilitation of mangrove forest is done as one effort that aims to maintain and return the mangrove forest function as one of life system supporters, especially in beach area. The most respondent ages of coast people of Gending, Pajarakan, dan Kraksaan districts, Probolinggo Regency are between 30 to 59 years old, i.e. as 86 people or 95.55% indicates that coast people are productive ages so they can be hoped very potential for having role in supporting mangrove ecosystem management of Probolinggo Regency coast. The average respondent educational rates are mostly Elementary School to Senior High School, i.e. as 76 people. Generally, human resources of coast people have relatively good education level. Thereby, it can be hoped to have positive potencies for the role of coast people themselves toward the mangrove ecosystem management support of Probolinggo Regency coast. The average most respondents have family burdens two and three people as six people or 6.67 percent. But, there are still three respondents who have not have family burdens. Generally, more and more members help in respondent’s jobs. The mangrove ecosystem management strategy of Probolinggo Regency coast is by involving people role (people and people figures) and governmental supports through the models of mangrove forest management strategy, the model of embankment cultivation management by entering mangrove as input resources of production facilities, and ecotourism management by the purpose of improving people income.

Full Text Available Awareness among people of reproductive age about the factors that influence fertility and reproductive outcomes, including medically assisted reproduction outcomes, is generally low. To improve awareness about the potentially modifiable factors that affect fertility and reproductive outcomes, ‘Your Fertility’, a fertility health promotion programme funded by the Australian Government, was established in 2011. This paper describes the development and evaluation of the reach of the Your Fertility programme from its inception in 2011 to June 2016. Systematically recorded outcomes for the programme’s key focus areas and Google Analytics data were collated. Key achievements include developing and maintaining an internationally renowned website that experiences high growth and demand for fertility-related information; by 2016, over 5 million users had viewed more than 10 million webpages, and over 96,000 users had engaged in programme messages across social media. Programme messages have reached more than 4 million Australian social media users, and a potential audience of 150 million through media coverage across more than 320 media features. More than 4200 education and health professionals have completed online learning modules, and external partnerships have been established with 14 separate organizations. Data collected over 5 years indicate that the Your Fertility programme meets a need for targeted, evidence-based, accessible fertility-related information.

We provide a solution to a major problem in visually guided reaching. Research has shown that binocular vision plays an important role in the online visual guidance of reaching, but the visual information and strategy used to guide a reach remains unknown. We propose a new theory of visual guidance of reaching including a new information variable, tau(alpha) (relative disparity tau), and a novel control strategy that allows actors to guide their reach trajectories visually by maintaining a constant proportion between tau(alpha) and its rate of change. The dynamical model couples the information to the reaching movement to generate trajectories characteristic of human reaching. We tested the theory in two experiments in which participants reached under conditions of darkness to guide a visible point either on a sliding apparatus or on their finger to a point-light target in depth. Slider apparatus controlled for a simple mapping from visual to proprioceptive space. When reaching with their finger, participants were forced, by perturbation of visual information used for feedforward control, to use online control with only binocular disparity-based information for guidance. Statistical analyses of trajectories strongly supported the theory. Simulations of the model were compared statistically to actual reaching trajectories. The results supported the theory, showing that tau(alpha) provides a source of information for the control of visually guided reaching and that participants use this information in a proportional rate control strategy.

Can donated media placements reach intended audiences?
Cooper, Crystale Purvis; Gelb, Cynthia A; Chu, Jennifer; Polonec, Lindsey
2013-09-01
Donated media placements for public service announcements (PSAs) can be difficult to secure, and may not always reach intended audiences. Strategies used by the Centers for Disease Control and Prevention's (CDC) Screen for Life: National Colorectal Cancer Action Campaign (SFL) to obtain donated media placements include producing a diverse mix of high-quality PSAs, co-branding with state and tribal health agencies, securing celebrity involvement, monitoring media trends to identify new distribution opportunities, and strategically timing the release of PSAs. To investigate open-ended recall of PSAs promoting colorectal cancer screening, CDC conducted 12 focus groups in three U.S. cities with men and women either nearing age 50 years, when screening is recommended to begin, or aged 50-75 years who were not in compliance with screening guidelines. In most focus groups, multiple participants recalled exposure to PSAs promoting colorectal cancer screening, and most of these individuals reported having seen SFL PSAs on television, in transit stations, or on the sides of public buses. Some participants reported exposure to SFL PSAs without prompting from the moderator, as they explained how they learned about the disease. Several participants reported learning key campaign messages from PSAs, including that colorectal cancer screening should begin at age 50 years and screening can find polyps so they can be removed before becoming cancerous. Donated media placements can reach and educate mass audiences, including millions of U.S. adults who have not been screened appropriately for colorectal cancer.

Recent studies indicate that the ability to mentally represent action using motor imagery declines with advanced age (>64 years). As the ability to represent action declines, the elderly may experience increasing difficulty with movement planning and execution. Here, we determined the association between estimation of reach via use of motor imagery and actual FR. Young adults (M=22 years) and older adults (M=66 years) estimated reach while standing with targets randomly presented in peripersonal (within actual reach) and extrapersonal (beyond reach) space. Imagined responses were compared to the individual's scaled maximum reach. FR, also while standing, was assessed using the standardized Functional Reach Test (FRT). Results for total score estimation accuracy showed that there was no difference for age; however, results for mean bias and distribution of error revealed that the older group underestimated while the younger group overestimated. In reference to FR, younger adults outperformed older adults (30 versus 14in.) and most prominent, only the younger group showed a significant relationship between estimation and FR. In addition to gaining insight to the effects of advanced age on the ability to mentally represent action and its association with movement execution, these results although preliminary, may have clinical implications based on the question of whether motor imagery training could improve movement estimations and how that might affect actual reach.

The rapid development of multiple national geospatial datasets related to topography, hydrology, and environmental characteristics in the past decade have provided new opportunities for the refinement of hydropower resource potential from undeveloped stream-reaches. Through 2011 to 2013, the Oak Ridge National Laboratory (ORNL) was tasked by the Department of Energy (DOE) Water Power Program to evaluate the new stream-reach development (NSD) resource potential for more than 3 million US streams. A methodology was designed that contains three main components: (1) identification of stream-reaches with high energy density, (2) topographical analysis of stream-reaches to estimate inundated surface area and reservoir storage, and (3) environmental attribution to spatially join information related to the natural ecological systems, social and cultural settings, policies, management, and legal constraints to stream-reaches of energy potential. An initial report on methodology (Hadjerioua et al., 2013) was later reviewed and revised based on the comments gathered from two peer review workshops. After implementing the assessment across the entire United States, major findings were summarized in this final report. The estimated NSD capacity and generation, including both higher-energy-density (>1 MW per reach) and lower-energy-density (<1 MW per reach) stream-reaches is 84.7 GW, around the same size as the existing US conventional hydropower nameplate capacity (79.5 GW; NHAAP, 2013). In terms of energy, the total undeveloped NSD generation is estimated to be 460 TWh/year, around 169% of average 2002 2011 net annual generation from existing conventional hydropower plants (272 TWh/year; EIA, 2013). Given the run-of-river assumption, NSD stream-reaches have higher capacity factors (53 71%), especially compared with conventional larger-storage peaking-operation projects that usually have capacity factors of around 30%. The highest potential is identified in the Pacific Northwest

Transparency of chemical risk assessment data under REACH.
Ingre-Khans, Ellen; Ågerstrand, Marlene; Beronius, Anna; Rudén, Christina
2016-12-08
The REACH regulation requires EU manufacturers and importers of substances to register information on the hazard and risk of their substances with the European Chemicals Agency (ECHA). Risk management of the substances is based on the provided information. It is known that conclusions on hazard and risk are influenced by expert judgements as well as potential conflict of interests. Thus, it is important that hazard and risk assessments are transparent and can be evaluated by a third party. The aim of this study is to scrutinize the transparency, i.e. the accessibility and comprehensibility, of information on substances registered under REACH. Data on repeated dose toxicity and hazard assessment conclusions were extracted for 60 substances from the REACH registration database available on the ECHA website. The data were compiled in a database for systematically evaluating the transparency of information related to the conclusions on hazard or risk. In addition, chemical safety reports (CSR) were requested from ECHA for five substances. The transparency of information on the hazard and risk of substances was found to be limited for several reasons. First, certain information was removed due to confidentiality and certain fields were not published because they could contain confidential information although the information had not been claimed confidential. Also, the extent to which registrants reported information varied, and the presentation of some data and certain terminology required further clarification. In addition, the data source for the majority of the key and supporting studies could not be identified due to confidentiality. Since registrants are only required to summarise studies, it cannot be verified whether all relevant information from non-public industry reports have been reported. Lastly, certain information related to the hazard and risk assessment were only reported in the CSR which is only available upon request; a time-consuming and work

Trends in radionuclide concentrations in Hanford Reach fish, 1982 through 1992
International Nuclear Information System (INIS)
Poston, T.M.
1994-06-01
Environmental monitoring has been conducted at the US Department of Energy's Hanford Site in southeast Washington State since 1945. Fish from the Hanford Reach of the Columbia River, which borders the Site, are monitored annually. The two objectives of this report were (1) to evaluate trends in the concentrations of radionuclides [e.g., 90 Sr and 137 Cs] in two species of Columbia River fish [smallmouth bass and mountain whitefish] sampled from the Hanford Reach from 1982 through 1992; and (2) to determine the impact of Hanford Site releases on these two species and carp and fall chinook salmon collected during this time frame. The evaluation found gradual reductions of 137 Cs in bass muscle and 90 Sr in bass and whitefish carcass from 1982 through 1992. Concentrations of 90 Sr in bass and whitefish followed the pattern established by reported Hanford Site releases from 1982 through 1992 and was supported by significant regression analyses comparing annual releases to sample concentration. Because data for carp have been collected only since 1990, the data base was inadequate for determining trends. Moreover, fall chinook salmon were only sampled once in this 11-year period. Concentrations of 90 Sr and 137 Cs in fish samples collected from distant background locations exceeded concentrations in Hanford Reach fish. Estimates of the dose from consumption of Hanford Reach fish were less than 0.001 times the National Council on Radiation Protection and Measurements and the US Department of Energy guideline of 100 mrem/yr

Full Text Available Under international law there are moral obligations on Nation States to ensure, protect and adhere to certain human rights standards. The difficulty is that if people do not know they have rights, do not have the confidence to assert their human rights or do not know the pathways to gain access to legal support and advice to action their human rights, then those human rights become unrealisable. It is now empirically established that unresolved legal problems result in poorer health and social outcomes. This article argues that the use of secondary consultations where a lawyer gives advice in a timely and approachable way to non-legal professionals (‘trusted intermediaries’ likely to have contact with the most vulnerable and disadvantaged clients, then this is an effective way of reaching clients who would otherwise not gain help or advice. The thesis for this article is that legal secondary consultations build capacity and confidence in professionals to both identify legal or human rights so they either support a client or, where appropriate, refer clients who would otherwise not get help because of a range of inhibitors. Legal secondary consultations enable people to identify their human rights and action them where otherwise they would be overlooked. The author draws on personal practical experience and initial findings from recent research in urban, outer urban and rural settings in Australia.

We interviewed 38 adults (ages 62–85 who lived in San Francisco or Oakland, California. Seven key themes emerged: (1 people express a wide range of expectations for neighborliness, from “we do not bother each other” to “we have keys to each other’s houses”, (2 social distance between “other” people impede a sense of connection, (3 ethnic differences in living arrangements affect activities and activity locations, (4 people try to stay busy, (5 people able to leave their homes do many activities outside their immediate residential neighborhoods, (6 access to a car is a necessity for most, and (7 it is unusual to plan for the future when mobility might become limited. Multiple locations influence older adults’ health, including residential neighborhoods. Older adults value mobility, active lives, and social connections.

Since 1996, CLASP and its implementing partner, LBNL, have assisted China in developing 11 minimum energy performance standards (MEPS) for 9 products and endorsement labels for 11 products including: refrigerators; air conditioners; clothes washers; televisions; printers; computers; monitors; fax machines; copiers; DVD/VCD players; external power supplies; and set-top boxes (under development). Before 2003, China's traditional approach to standards development involved small increases in efficiency requirements for implementation within 6 months of a standard's approval. Since 2003, China has adopted a new approach in setting MEPS. This new approach involves the development of two tiers of standards--one for initial implementation and a second tier at a more aggressive level of energy efficiency for implementation three to five years later. The second-tier standard is also referred to as a 'reach standard'. Reach standards have now been developed in China for: color TVs; refrigerators; air conditioners; and external power supplies. This report is presented in five sections. After the introduction in Section 1, Section 2 analyzes the distribution of the efficiency of refrigerators and air-conditioners in China based on data collected by the China Energy Label Center for the mandatory energy information label program. The results provide an assessment of the adoption of reach standards for these two products. Section 3 summarizes on-going collaborations with Shanghai related to early local adoption of reach standards, and presents both the impact and an analysis of barriers to the local adoption of reach standard for air-conditioners. Section 4 offers suggestions for local governments on how to move forward in adopting reach standards in their localities and concludes with a summary of the results and a plan for developing local capacity in

REACH: an effective catalyst for scaling up priority nutrition interventions at the country level.
Pearson, Brenda L; Ljungqvist, Björn
2011-06-01
Renewed Efforts Against Child Hunger (REACH) is the joint United Nations initiative to address Millennium Development Goal (MDG) 10, Target 3, i.e., to halve the proportion of underweight children under 5 years old by 2015. The United Nations Food and Agriculture Organization (FAO), the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), the World Food Programme (WFP), and the International Fund for Agricultural Development (IFAD) developed and tested a facilitation mechanism to act as a catalyst for scaling up multisectoral nutrition activities. The UN-REACH partners developed pilot projects in Mauritania and Lao PDR from 2008 to 2010 and deployed facilitators to improve nutrition governance and coordination. Review missions were conducted in February 2011 to assess the REACH approach and what it achieved. The UN review mission members reviewed documents, assessed policy and management indicators, conducted qualitative interviews, and discussed findings with key stakeholders, including the most senior UN nutrition directors from all agencies. Among other UN-REACH achievements, the Prime Minister of Mauritania agreed to preside over a new National Nutrition Development Council responsible for high-level decision-making and setting national policy objectives. REACH facilitated the completion of Lao's first national Nutrition Strategy and Plan of Action and formation of the multistakeholder Nutrition Task Force. During the REACH engagement, coordination, joint advocacy, situation analysis, policy development, and joint UN programming for nutrition were strengthened in Lao PDR and Mauritania. Improvements in the nutrition governance and management mechanisms in Mauritania and Lao PDR were observed during the period of REACH support through increased awareness of nutrition as a key development objective, establishment of governmental multisectoral coordinating mechanisms, improved government capacity, and new joint UN-government nutrition

Pharmaceutical intervention targets arm flexor spasticity with an often-unsuccessful goal of improving function. Flexion synergy is a related motor impairment that may be inadvertently neglected. Here, flexor spasticity and flexion synergy are disentangled to determine their contributions to reaching dysfunction. Twenty-six individuals participated. A robotic device systematically modulated shoulder abduction loading during ballistic reaching. Elbow muscle electromyography data were partitioned into windows delineated by elbow joint velocity allowing for the separation of synergy- and spasticity-related activation. Reaching velocity decreased with abduction loading (psynergy increased with abduction loading (psynergy is the predominant contributor to reaching dysfunction while flexor spasticity appears only relevant during unnaturally occurring passively supported movement. Interventions targeting flexion synergy should be leveraged in future stroke recovery trials. Copyright © 2017 International Federation of Clinical Neurophysiology. Published by Elsevier B.V.

The typically elevated natural attenuation capacity of riverbed-hyporheic zones is expected to decrease chlorinated hydrocarbon (CHC) groundwater plume discharges to river receptors through dechlorination reactions. The aim of this study was to assess physico-chemical processes controlling field-scale variation in riverbed-hyporheic zone dechlorination of a TCE groundwater plume discharge to an urban river reach. The 50-m long pool-riffle-glide reach of the River Tame in Birmingham (UK) studied is a heterogeneous high energy river environment. The shallow riverbed was instrumented with a detailed network of multilevel samplers. Freeze coring revealed a geologically heterogeneous and poorly sorted riverbed. A chlorine number reduction approach provided a quantitative indicator of CHC dechlorination. Three sub-reaches of contrasting behaviour were identified. Greatest dechlorination occurred in the riffle sub-reach that was characterised by hyporheic zone flows, moderate sulphate concentrations and pH, anaerobic conditions, low iron, but elevated manganese concentrations with evidence of sulphate reduction. Transient hyporheic zone flows allowing input to varying riverbed depths of organic matter are anticipated to be a key control. The glide sub-reach displayed negligible dechlorination attributed to the predominant groundwater baseflow discharge condition, absence of hyporheic zone, transition to more oxic conditions and elevated sulphate concentrations expected to locally inhibit dechlorination. The tail-of-pool-riffle sub-reach exhibited patchy dechlorination that was attributed to sub-reach complexities including significant flow bypass of a low permeability, high organic matter, silty unit of high dechlorination potential. A process-based conceptual model of reach-scale dechlorination variability was developed. Key findings of practitioner relevance were: riverbed-hyporheic zone CHC dechlorination may provide only a partial, somewhat patchy barrier to CHC

This review seeks to connect the scientific theory of mixture toxicity to its implementation within different regulatory frameworks. The aim is to demonstrate how mixture toxicity assessment can be more thoroughly integrated into the European chemical regulations, REACH and the Water Framework...... of how the methods could be applied within REACH and WFD. It is concluded that oncentration addition should be applied as a default model for mixture toxicity assessment. Furthermore, it is concluded that REACH and WFD only include mixture toxicity assessments in specific situations. However, it is shown...

Intensity refers to the amount of effort or rate of work undertaken during exercise. People receiving rehabilitation after stroke frequently do not reach the moderate to high intensity exercise recommended to maximise gains. To explore the factors that influence the acceptability of, and engagement with, a high intensity group-based exercise programme for people with stroke. This qualitative descriptive study included 14 people with stroke who had completed a 12-week, high intensity group-based exercise rehabilitation programme. Semi-structured interviews were used to explore the acceptability of high intensity exercise and the barriers and facilitators to engagement. Interviews were recorded, transcribed and analysed using qualitative content analysis. The participants found high intensity exercise rehabilitation acceptable despite describing the exercise intensity as hard and reporting post-exercise fatigue. Participants accepted the fatigue as a normal response to exercise, and it did not appear to negatively influence engagement. The ease with which an individual engaged in high intensity exercise rehabilitation appeared to be mediated by inter-related factors, including: seeing progress, sourcing motivation, working hard, the people involved and the fit with the person and their life. Participants directly related the intensity of their effort to the gains that they made. In this study, people with stroke viewed training at higher intensities as a facilitator, not a barrier, to engagement in exercise rehabilitation. The findings may challenge assumptions about the influence of exercise intensity on engagement.

To unravel the factors that regulate DOC dynamics in the freshwater tidal reaches of the Schelde estuary, DOC concentration and biodegradability were monitored in the upper Schelde estuary and its major tributaries. Although the Schelde estuary possesses a densely populated and industrialized...... catchment, our data suggest that the bulk of DOC in the freshwater tidal reaches is not derived from waste water. This was concluded from the low biodegradability of DOC (on average 9%), DOC concentrations that are close to the mean for European rivers (4.61 mg/l) and the absence of an inverse relationship....../l), these blooms did not appear to produce large quantities of DOC in the freshwater tidal reaches as DOC concentrations were low when phytoplankton biomass was high. The fact that DOC concentrations were high in winter and decreased in summer suggests a predominantly terrestrial source of DOC in the freshwater...

Effects of accuracy constraints on reach-to-grasp movements in cerebellar patients.
Rand, M K; Shimansky, Y; Stelmach, G E; Bracha, V; Bloedel, J R
2000-11-01
Reach-to-grasp movements of patients with pathology restricted to the cerebellum were compared with those of normal controls. Two types of paradigms with different accuracy constraints were used to examine whether cerebellar impairment disrupts the stereotypic relationship between arm transport and grip aperture and whether the variability of this relationship is altered when greater accuracy is required. The movements were made to either a vertical dowel or to a cross bar of a small cross. All subjects were asked to reach for either target at a fast but comfortable speed, grasp the object between the index finger and thumb, and lift it a short distance off the table. In terms of the relationship between arm transport and grip aperture, the control subjects showed a high consistency in grip aperture and wrist velocity profiles from trial to trial for movements to both the dowel and the cross. The relationship between the maximum velocity of the wrist and the time at which grip aperture was maximal during the reach was highly consistent throughout the experiment. In contrast, the time of maximum grip aperture and maximum wrist velocity of the cerebellar patients was quite variable from trial to trial, and the relationship of these measurements also varied considerably. These abnormalities were present regardless of the accuracy requirement. In addition, the cerebellar patients required a significantly longer time to grasp and lift the objects than the control subjects. Furthermore, the patients exhibited a greater grip aperture during reach than the controls. These data indicate that the cerebellum contributes substantially to the coordination of movements required to perform reach-to-grasp movements. Specifically, the cerebellum is critical for executing this behavior with a consistent, well-timed relationship between the transport and grasp components. This contribution is apparent even when accuracy demands are minimal.

Effects of turbulent hyporheic mixing on reach-scale solute transport
Roche, K. R.; Li, A.; Packman, A. I.
2017-12-01
Turbulence rapidly mixes solutes and fine particles into coarse-grained streambeds. Both hyporheic exchange rates and spatial variability of hyporheic mixing are known to be controlled by turbulence, but it is unclear how turbulent mixing influences mass transport at the scale of stream reaches. We used a process-based particle-tracking model to simulate local- and reach-scale solute transport for a coarse-bed stream. Two vertical mixing profiles, one with a smooth transition from in-stream to hyporheic transport conditions and a second with enhanced turbulent transport at the sediment-water interface, were fit to steady-state subsurface concentration profiles observed in laboratory experiments. The mixing profile with enhanced interfacial transport better matched the observed concentration profiles and overall mass retention in the streambed. The best-fit mixing profiles were then used to simulate upscaled solute transport in a stream. Enhanced mixing coupled in-stream and hyporheic solute transport, causing solutes exchanged into the shallow subsurface to have travel times similar to the water column. This extended the exponential region of the in-stream solute breakthrough curve, and delayed the onset of the heavy power-law tailing induced by deeper and slower hyporheic porewater velocities. Slopes of observed power-law tails were greater than those predicted from stochastic transport theory, and also changed in time. In addition, rapid hyporheic transport velocities truncated the hyporheic residence time distribution by causing mass to exit the stream reach via subsurface advection, yielding strong exponential tempering in the in-stream breakthrough curves at the timescale of advective hyporheic transport through the reach. These results show that strong turbulent mixing across the sediment-water interface violates the conventional separation of surface and subsurface flows used in current models for solute transport in rivers. Instead, the full distribution of

Understanding "people" people.
Butler, Timothy; Waldroop, James
2004-06-01
Nearly all areas of business--not just sales and human resources--call for interpersonal savvy. Relational know-how comprises a greater variety of aptitudes than many executives think. Some people can "talk a dog off a meat truck," as the saying goes. Others are great at resolving interpersonal conflicts. Some have a knack for translating high-level concepts for the masses. And others thrive when they're managing a team. Since people do their best work when it most closely matches their interests, the authors contend, managers can increase productivity by taking into account employees' relational interests and skills when making personnel choices and project assignments. After analyzing psychological tests of more than 7,000 business professionals, the authors have identified four dimensions of relational work: influence, interpersonal facilitation, relational creativity, and team leadership. This article explains each one and offers practical advice to managers--how to build a well-balanced team, for instance, and how to gauge the relational skills of potential employees during interviews. To determine whether a job candidate excels in, say, relational creativity, ask her to describe her favorite advertising campaign, slogan, or image and tell you why she finds it to be so effective. Understanding these four dimensions will help you get optimal performance from your employees, appropriately reward their work, and assist them in setting career goals. It will also help you make better choices when it comes to your own career development. To get started, try the authors' free online assessment tool, which will measure both your orientation toward relational work in general and your interest level in each of its four dimensions.

To assess the effects of a texture-modified food program for dysphagia on the nutritional, biochemical and functional profile in a cohort of institutionalised older people in Italy. Dysphagic institutionalised older people, often also affected by dementia, are frequently exposed to malnutrition. Malnutrition in older people has negative effects on mortality, days of hospitalisation, infection, wound healing and risk of pressure injuries. Therefore, it is very important to prevent malnutrition in this frail population. A pre-post study without a control group. The study included 479 dysphagic institutionalised older people from 20 nursing homes. Anthropometrical, biochemical, nutritional and functional parameters were collected retrospectively, 6 months before the study intervention, at time zero and, prospectively for 6 months after implementing the NUTRICARE food programme, for a total of nine evaluations. The NUTRICARE programme includes meals without nutritional supplementation, and personalised levels of density, viscosity, texture and particle size. The total mean body mass index of our sample passed from 17.88-19.00; body weight averagely improved by 7.19%, as well as their nutritional and biochemical profiles. There was a progressive improvement of total protein and serum albumin values. Nutritional parameters (serum transferrin and lymphocytes) displayed similar changes. Plasma lymphocytes reached normal levels in 98.23% of the sample. Plasma creatinine levels remained steady throughout the study and within the normal range. No side effects were reported. The NUTRICARE food programme with a adequate proteins, calories, balanced nutritional and bromatological properties, and appropriate texture and palatability significantly improved the nutritional, biochemical and functional profile in a cohort of institutionalised dysphagic older people. The introduction of a balanced nutritional programme, using high-quality natural ingredients, appropriate texture and

Interaction torque contributes to planar reaching at slow speed
Directory of Open Access Journals (Sweden)
Hoshi Fumihiko
2008-10-01
Full Text Available Abstract Background How the central nervous system (CNS organizes the joint dynamics for multi-joint movement is a complex problem, because of the passive interaction among segmental movements. Previous studies have demonstrated that the CNS predictively compensates for interaction torque (INT which is arising from the movement of the adjacent joints. However, most of these studies have mainly examined quick movements, presumably because the current belief is that the effects of INT are not significant at slow speeds. The functional contribution of INT for multijoint movements performed in various speeds is still unclear. The purpose of this study was to examine the contribution of INT to a planer reaching in a wide range of motion speeds for healthy subjects. Methods Subjects performed reaching movements toward five targets under three different speed conditions. Joint position data were recorded using a 3-D motion analysis device (50 Hz. Torque components, muscle torque (MUS, interaction torque (INT, gravity torque (G, and net torque (NET were calculated by solving the dynamic equations for the shoulder and elbow. NET at a joint which produces the joint kinematics will be an algebraic sum of torque components; NET = MUS - G - INT. Dynamic muscle torque (DMUS = MUS-G was also calculated. Contributions of INT impulse and DMUS impulse to NET impulse were examined. Results The relative contribution of INT to NET was not dependent on speed for both joints at every target. INT was additive (same direction to DMUS at the shoulder joint, while in the elbow DMUS counteracted (opposed to INT. The trajectory of reach was linear and two-joint movements were coordinated with a specific combination at each target, regardless of motion speed. However, DMUS at the elbow was opposed to the direction of elbow movement, and its magnitude varied from trial to trial in order to compensate for the variability of INT. Conclusion Interaction torque was important at

Evaluating Remapped Physical Reach for Hand Interactions with Passive Haptics in Virtual Reality.
Han, Dustin T; Suhail, Mohamed; Ragan, Eric D
2018-04-01
Virtual reality often uses motion tracking to incorporate physical hand movements into interaction techniques for selection and manipulation of virtual objects. To increase realism and allow direct hand interaction, real-world physical objects can be aligned with virtual objects to provide tactile feedback and physical grasping. However, unless a physical space is custom configured to match a specific virtual reality experience, the ability to perfectly match the physical and virtual objects is limited. Our research addresses this challenge by studying methods that allow one physical object to be mapped to multiple virtual objects that can exist at different virtual locations in an egocentric reference frame. We study two such techniques: one that introduces a static translational offset between the virtual and physical hand before a reaching action, and one that dynamically interpolates the position of the virtual hand during a reaching motion. We conducted two experiments to assess how the two methods affect reaching effectiveness, comfort, and ability to adapt to the remapping techniques when reaching for objects with different types of mismatches between physical and virtual locations. We also present a case study to demonstrate how the hand remapping techniques could be used in an immersive game application to support realistic hand interaction while optimizing usability. Overall, the translational technique performed better than the interpolated reach technique and was more robust for situations with larger mismatches between virtual and physical objects.

Recent studies suggest that stream restoration at the reach scale may not increase stream biodiversity, raising concerns about the utility of this conservation practice. We examined whether reach-scale restoration in disturbed agricultural streams was associated with changes in macroinvertebrate community structure (total macroinvertebrate taxon richness, total macroinvertebrate density, Ephemeroptera, Plecoptera, Trichoptera [EPT] taxon richness, % abundance of EPT taxa) or secondary production (macroinvertebrate biomass over time). We collected macroinvertebrate samples over the course of 1 y from restored and unrestored reaches of 3 streams in southern Minnesota and used generalized least-square (GLS) models to assess whether measures of community structure were related to reach type, stream site, or sampling month. After accounting for effects of stream site and time, we found no significant difference in total taxon richness or % abundance of EPT taxa between restored and unrestored reaches. However, the number of EPT taxa and macroinvertebrate density were significantly higher in restored than in unrestored reaches. We compared secondary production estimates among study reaches based on 95th-percentile confidence intervals generated via bootstrapping. In each study stream, secondary production was significantly (2–3×) higher in the restored than in the unrestored reach. Higher productivity in the restored reaches was largely a result of the disproportionate success of a few dominant, tolerant taxa. Our findings suggest that reach-scale restoration may have ecological effects that are not detected by measures of total taxon richness alone.

Excessive amounts of nutrients and dissolved organic matter in freshwater bodies affect aquatic ecosystems. In this study, the spatial and temporal variability in nitrate (NO3), dissolved organic carbon (DOC) and soluble reactive phosphorus (SRP) was analyzed in the Selke river continuum from headwaters draining 1 - 3 km² catchments to downstream reaches representing spatially integrated signals from 184 - 456 km² catchments (part of TERENO - Terrestrial Environmental Observatories, in Germany). Three headwater catchments were selected as archetypes of the main landscape units (land use x lithology) present in the Selke catchment. Export regimes in headwater catchments were interpreted in terms of NO3, DOC and SRP land-to-stream transfer processes. Headwater signals were subtracted from downstream signals, with the differences interpreted in terms of in-stream processes and contribution of point-source emissions. The seasonal dynamics for NO3 were opposite those of DOC and SRP in all three headwater catchments, and spatial differences also showed NO3 contrasting with DOC and SRP. These dynamics were interpreted as the result of the interplay of hydrological and biogeochemical processes, for which riparian zones were hypothesized to play a determining role. In the two downstream reaches, NO3 was transported almost conservatively, whereas DOC was consumed and produced in the upper and lower river sections, respectively. The natural export regime of SRP in the three headwater catchments mimicked a point-source signal, which may lead to overestimation of domestic contributions in the downstream reaches. Monitoring the river continuum from headwaters to downstream reaches proved effective to investigate jointly land-to-stream and in-stream transport and transformation processes.

Development of reaching during mid-childhood from a Developmental Systems perspective.
Golenia, Laura; Schoemaker, Marina M; Otten, Egbert; Mouton, Leonora J; Bongers, Raoul M
2018-01-01
Inspired by the Developmental Systems perspective, we studied the development of reaching during mid-childhood (5-10 years of age) not just at the performance level (i.e., endpoint movements), as commonly done in earlier studies, but also at the joint angle level. Because the endpoint position (i.e., the tip of the index finger) at the reaching target can be achieved with multiple joint angle combinations, we partitioned variability in joint angles over trials into variability that does not (goal-equivalent variability, GEV) and that does (non-goal-equivalent variability, NGEV) influence the endpoint position, using the Uncontrolled Manifold method. Quantifying this structure in joint angle variability allowed us to examine whether and how spatial variability of the endpoint at the reaching target is related to variability in joint angles and how this changes over development. 6-, 8- and 10-year-old children and young adults performed reaching movements to a target with the index finger. Polynomial trend analysis revealed a linear and a quadratic decreasing trend for the variable error. Linear decreasing and cubic trends were found for joint angle standard deviations at movement end. GEV and NGEV decreased gradually with age, but interestingly, the decrease of GEV was steeper than the decrease of NGEV, showing that the different parts of the joint angle variability changed differently over age. We interpreted these changes in the structure of variability as indicating changes over age in exploration for synergies (a family of task solutions), a concept that links the performance level with the joint angle level. Our results suggest changes in the search for synergies during mid-childhood development.

How are we supposed to decide the rights and wrongs of banning smoking in bars, restricting adverts for junk food, nagging people into being screened for cancers, or banning the sale of party pills? The aim of this paper is to think through the political ethics of trying to make people healthier through influencing or restricting their choices. This paper covers: (1) Paternalism. What it is, what it assumes. (2) The place of health in well-being, and how this makes paternalism problematic. (3) The mistakes people make in acting in their own interests, and the implications for pro-health paternalism. (4) Autonomy objections to paternalism. The paper (5) finishes on a note of hope, by commending the currently fashionable libertarian paternalism: trying to have one's carrot cake and eat it too. A persistent theme is that thinking sensibly about making people healthier needs subtlety, not broad, ringing declarations.

Generalization of unconstrained reaching with hand-weight changes.
Yan, Xiang; Wang, Qining; Lu, Zhengchuan; Stevenson, Ian H; Körding, Konrad; Wei, Kunlin
2013-01-01
Studies of motor generalization usually perturb hand reaches by distorting visual feedback with virtual reality or by applying forces with a robotic manipulandum. Whereas such perturbations are useful for studying how the central nervous system adapts and generalizes to novel dynamics, they are rarely encountered in daily life. The most common perturbations that we experience are changes in the weights of objects that we hold. Here, we use a center-out, free-reaching task, in which we can manipulate the weight of a participant's hand to examine adaptation and generalization following naturalistic perturbations. In both trial-by-trial paradigms and block-based paradigms, we find that learning converges rapidly (on a timescale of approximately two trials), and this learning generalizes mostly to movements in nearby directions with a unimodal pattern. However, contrary to studies using more artificial perturbations, we find that the generalization has a strong global component. Furthermore, the generalization is enhanced with repeated exposure of the same perturbation. These results suggest that the familiarity of a perturbation is a major factor in movement generalization and that several theories of the neural control of movement, based on perturbations applied by robots or in virtual reality, may need to be extended by incorporating prior influence that is characterized by the familiarity of the perturbation.

Networks of conforming or nonconforming individuals tend to reach satisfactory decisions.
Ramazi, Pouria; Riehl, James; Cao, Ming
2016-11-15
Binary decisions of agents coupled in networks can often be classified into two types: "coordination," where an agent takes an action if enough neighbors are using that action, as in the spread of social norms, innovations, and viral epidemics, and "anticoordination," where too many neighbors taking a particular action causes an agent to take the opposite action, as in traffic congestion, crowd dispersion, and division of labor. Both of these cases can be modeled using linear-threshold-based dynamics, and a fundamental question is whether the individuals in such networks are likely to reach decisions with which they are satisfied. We show that, in the coordination case, and perhaps more surprisingly, also in the anticoordination case, the agents will indeed always tend to reach satisfactory decisions, that is, the network will almost surely reach an equilibrium state. This holds for every network topology and every distribution of thresholds, for both asynchronous and partially synchronous decision-making updates. These results reveal that irregular network topology, population heterogeneity, and partial synchrony are not sufficient to cause cycles or nonconvergence in linear-threshold dynamics; rather, other factors such as imitation or the coexistence of coordinating and anticoordinating agents must play a role.

In this paper, we propose a novel polar coded intensity modulation direct detection (IM/DD) optical orthogonal frequency division multiplexing (OFDM) system for short reach system. A method of evaluating the channel signal noise ratio (SNR) is proposed for soft-demodulation. The experimental results demonstrate that, compared to the conventional case, ∼9.5 dB net coding gain (NCG) at the bit error rate (BER) of 1E-3 can be achieved after 40-km standard single mode fiber (SSMF) transmission. Based on the experimental result, (512,256) polar code with low complexity and satisfactory BER performance meets the requirement of low latency in short reach system, which is a promising candidate for latency-stringent short reach optical system.

Among adults with type 2 diabetes mellitus (T2DM), adherence to recommended self-care activities is suboptimal, especially among racial and ethnic minorities with low income. Self-care nonadherence is associated with having worse glycemic control and diabetes complications. Text messaging interventions are improving the self-care of adults with T2DM, but few have been tested with disadvantaged populations. To develop Rapid Education/Encouragement And Communications for Health (REACH), a tailored, text messaging intervention to support the self-care adherence of disadvantaged patients with T2DM, based on the Information-Motivation-Behavioral skills model. We then tested REACH's usability to make improvements before evaluating its effects. We developed REACH's content and functionality using an empirical and theory-based approach, findings from a previously pilot-tested intervention, and the expertise of our interdisciplinary research team. We recruited 36 adults with T2DM from Federally Qualified Health Centers to participate in 1 of 3 rounds of usability testing. For 2 weeks, participants received daily text messages assessing and promoting self-care, including tailored messages addressing users' unique barriers to adherence, and weekly text messages with adherence feedback. We analyzed quantitative and qualitative user feedback and system-collected data to improve REACH. Participants were, on average, 52.4 (SD 9.5) years old, 56% (20/36) female, 63% (22/35) were a racial or ethnic minority, and 67% (22/33) had an income less than US $35,000. About half were taking insulin, and average hemoglobin A1c level was 8.2% (SD 2.2%). We identified issues (eg, user concerns with message phrasing, technical restrictions with responding to assessment messages) and made improvements between testing rounds. Overall, participants favorably rated the ease of understanding (mean 9.6, SD 0.7) and helpfulness (mean 9.3, SD 1.4) of self-care promoting text messages on a scale of 1

Full Text Available We are moving away from the year 2000, and the goal of "health for all" remains distant. Economic globalization, which many consider to be one of the most serious threats to health, moves ahead, along with globalization of international health policies. A small number of powerful actors are in charge of setting the agenda, and they relegate to an inferior position the World Health Organization, which has moved away from the goal of "health for all." All of this has helped to promote a neoliberal mentality in the field of health. The People's Health Movement was created with the objective of reestablishing the right to comprehensive health and to development with equity as principal priorities of health policies at the local, national, and international levels. The People's Health Movement uses as a strategy the People's Charter for Health, which was approved at the first People's Health Assembly, which was held in Bangladesh in 2000. The Charter expresses collective concerns and the belief in a better and healthier world as a meeting point in order to promote a world health movement and a call for radical action. In July 2005 the People's Health Movement will hold the People's Health Assembly 2, in the city of Cuenca, Ecuador. The slogan of that meeting will be "The voices of the earth are calling!-let's build a healthy world." Among the topics that will be examined at the meeting are: health as a fundamental human right; militarization and occupation; environmental degradation; emerging and reemerging pandemics; equity, poverty, and health; the importance of cultural diversity; social and political violence; health in the hands of the people; health at work; traditional medicine and bioenergetic medicine; gender; and health sector reform. The objective of the People's Health Movement is to help to reach the Millennium Development Goals and to smooth the path toward attaining health for all, in Latin America and the Caribbean as well as in the

Physics reach of β-beams and ν-factories: the problem of degeneracies
International Nuclear Information System (INIS)
Rigolin, S.
2006-01-01
We discuss the physics reach of β-Beams and ν-Factories from a theoretical perspective, having as a guideline the problem of degeneracies. The presence of degenerate solutions in the measure of the neutrino oscillation parameters θ 13 and δ is, in fact, the main problem that have to be addressed in planning future neutrino oscillation experiments. If degeneracies are not (at least partially) solved, it will be almost impossible to perform, at any future facility, precise measurements of θ 13 and/or δ. After a pedagogical introduction on why degenerate solutions arise and how we can get rid of them, we analyze the physics reach of current β-beam and ν-factory configurations. The physics reach of the 'standard' β-Beam is severely affected by degeneracies while a better result can be obtained by higher-γ setups. At the ν-Factory the combination of Golden and Silver channels can solve the eightfold degeneracy down to sin 2 θ 13 = -3

To study the ability to reach orgasm after robot-assisted laparoscopic prostatectomy (RALP) in relation to demographic, cancer-related, and surgical variables, and the use of erectile aids. In this cross-sectional study at a mean of 3 years after RALP at Oslo University Hospital, 982 men were invited to complete a mailed questionnaire, and 777 responded. Respondents who reported postoperative radiotherapy or hormone treatment, or did not report on orgasm were omitted, leaving 609 patients for analysis. Ability to reach orgasm was rated on 1 question from The Expanded Prostate Cancer Index Composite 26-item version, and dichotomized into "good" or "poor." Overall, 27% of the men reported good ability to reach orgasm: 22% among those did not use erectile aids and 34% among those did (P = .001). Univariate analysis of men with good versus poor ability to reach orgasm showed many significant differences. In multivariate analysis, being older, having a reduced physical quality of life, and erectile dysfunction were significantly associated with poor ability to reach orgasm. Erectile dysfunction showed an odds ratio of 4.86 for poor orgasmic ability. The 48% of men who used erectile aids had significantly better orgasmic ability than the nonusers. In our sample, 27% had good ability to reach orgasm at a mean of 3 years after RALP. Poor orgasmic ability was associated with being older, poor erectile function, and a reduced physical quality of life. Using erectile aids increased the rate of good ability to reach orgasm.

The purpose of this study was to determine whether a face-to-face meeting with patients by a telephonic case manager prehospital discharge would result in increased telephone follow-up (TFU) reach rates posthospital discharge. Acute care adult medicine inpatient units. A quasiexperimental design was utilized. Two adult inpatient medicine units were selected as the intervention and comparison groups. The framework of the study is the transitions theory. A convenience sampling technique was used, whereby 88 eligible patients on the intervention unit received face-to-face meetings prehospital discharge whereas 123 patients on the comparison unit received standard care (no face-to-face meetings). Cross-tabulation and chi-square tests were employed to examine the association of face-to-face meeting intervention and TFU reach rates. Implementing brief (face-to-face meetings by a telephonic case manager prehospital discharge resulted in a TFU reach rate of 87% on the intervention unit, whereas the comparison unit only had a 58% TFU reach rate (p communication with more patients posthospital discharge. A brief prehospital discharge face-to-face meeting with patients assisted them to understand the reasons for a posthospital discharge telephone call, identified the best times to call using accurate telephone numbers, and taught patients how best to prepare for the call. In addition, by meeting patients face-to-face, the telephonic case manager was no longer an unknown person on the telephone asking them questions about their medical condition. These factors combined may have significantly helped to increase TFU reach rates.

ICT Interface Design for Ageing People and People with Dementia
Wallace, Jonathan; Mulvenna, Maurice D.; Martin, Suzanne; Stephens, Sharon; Burns, William
Ageing population trends, rising healthcare costs and social and digital inclusion are all factors in the background to the problem of older adults interacting with technology. Approaches to address "physical accessibility" and "access to technology" issues, as well as training for existing systems are evident, yet a usability issue still prevails. The primary aim of this chapter is to provide an overview of the research and literature and discuss the differing contexts in which older people and people with dementia interact with computerised systems and their associated issues.

Neurons in Primary Motor Cortex Encode Hand Orientation in a Reach-to-Grasp Task.
Ma, Chaolin; Ma, Xuan; Fan, Jing; He, Jiping
2017-08-01
It is disputed whether those neurons in the primary motor cortex (M1) that encode hand orientation constitute an independent channel for orientation control in reach-to-grasp behaviors. Here, we trained two monkeys to reach forward and grasp objects positioned in the frontal plane at different orientation angles, and simultaneously recorded the activity of M1 neurons. Among the 2235 neurons recorded in M1, we found that 18.7% had a high correlation exclusively with hand orientation, 15.9% with movement direction, and 29.5% with both movement direction and hand orientation. The distributions of neurons encoding hand orientation and those encoding movement direction were not uniform but coexisted in the same region. The trajectory of hand rotation was reproduced by the firing patterns of the orientation-related neurons independent of the hand reaching direction. These results suggest that hand orientation is an independent component for the control of reaching and grasping activity.

Stereotypical reaching movements of the octopus involve both bend propagation and arm elongation.
Hanassy, S; Botvinnik, A; Flash, T; Hochner, B
2015-05-13
The bend propagation involved in the stereotypical reaching movement of the octopus arm has been extensively studied. While these studies have analyzed the kinematics of bend propagation along the arm during its extension, possible length changes have been ignored. Here, the elongation profiles of the reaching movements of Octopus vulgaris were assessed using three-dimensional reconstructions. The analysis revealed that, in addition to bend propagation, arm extension movements involve elongation of the proximal part of the arm, i.e., the section from the base of the arm to the propagating bend. The elongations are quite substantial and highly variable, ranging from an average strain along the arm of -0.12 (i.e. shortening) up to 1.8 at the end of the movement (0.57 ± 0.41, n = 64 movements, four animals). Less variability was discovered in an additional set of experiments on reaching movements (0.64 ± 0.28, n = 30 movements, two animals), where target and octopus positions were kept more stationary. Visual observation and subsequent kinematic analysis suggest that the reaching movements can be broadly segregated into two groups. The first group involves bend propagation beginning at the base of the arm and propagating towards the arm tip. In the second, the bend is formed or present more distally and reaching is achieved mainly by elongation and straightening of the segment proximal to the bend. Only in the second type of movements is elongation significantly positively correlated with the distance of the bend from the target. We suggest that reaching towards a target is generated by a combination of both propagation of a bend along the arm and arm elongation. These two motor primitives may be combined to create a broad spectrum of reaching movements. The dynamical model, which recapitulates the biomechanics of the octopus muscular hydrostatic arm, suggests that achieving the observed elongation requires an extremely low ratio of longitudinal to transverse muscle

Full Text Available Background: Among health care workers the highest level of work related back injuries are more affected in nurses. There were many studies done to assess low back pain by using different tools. So this study aimed to identify the prevalence low back pain disability among female nursing professionals and the association between BMI, functional reach test and low back pain, so that a better tool can be used during the clinical examination for the betterment of the patient. The objective of the study is to identify the prevalence of low back pain disability, the association of Low Back Pain(LBP with BMI and functional reach test among female nursing professionals. Methods: A total of 256 subjects were assessed for disability due to back pain using OswestryLBP Disability Questionnaire and the prevalence of disability was determined. The sit and reach test, forward reach test and their BMI were calculated for those who had a disability score of 20 and above (n=87. Results: Data was analyzed using Pearson’s correlation.The study result showed a significant correlation (p=0.03 of sit and reach test with low back pain disability scores. There was a negative correlationseen among BMI and LBP disability score forward reach test and LBP disability score, and BMI and no low back pain disability score. Conclusion: The prevalence of LBP disability among nursing professionals was 33.9%. This study suggest that sit and reach test can be used as an indicator of low back pain. Whereas BMI and forward reach test do not indicate low back pain.

With an interest in identifying the variables that constrain arm choice when reaching, the authors had 11 right-handed participants perform free-choice and assigned-limb reaches at 9 object positions. The right arm was freely selected 100% of the time when reaching to positions at 30° and 40° into right hemispace. However, the left arm was freely selected to reach to positions at -30° and -40° in left hemispace 85% of the time. A comparison between free- and assigned-limb reaching kinematics revealed that free limb selection when reaching to the farthest positions was constrained by joint amplitude requirements and the time devoted to limb deceleration. Differences between free- and assigned-arm reaches were not evident when reaching to the midline and positions of ±10°, even though the right arm was freely selected most often for these positions. Different factors contribute to limb selection as a function of distance into a specific hemispace.

Reach on sound: a key to object permanence in visually impaired children.

2011-04-01
The capacity to reach an object presented through sound clue indicates, in the blind child, the acquisition of object permanence and gives information over his/her cognitive development. To assess cognitive development in congenitally blind children with or without multiple disabilities. Cohort study. Thirty-seven congenitally blind subjects (17 with associated multiple disabilities, 20 mainly blind) were enrolled. We used Bigelow's protocol to evaluate "reach on sound" capacity over time (at 6, 12, 18, 24, and 36 months), and a battery of clinical, neurophysiological and cognitive instruments to assess clinical features. Tasks n.1 to 5 were acquired by most of the mainly blind children by 12 months of age. Task 6 coincided with a drop in performance, and the acquisition of the subsequent tasks showed a less agehomogeneous pattern. In blind children with multiple disabilities, task acquisition rates were lower, with the curves dipping in relation to the more complex tasks. The mainly blind subjects managed to overcome Fraiberg's "conceptual problem"--i.e., they acquired the ability to attribute an external object with identity and substance even when it manifested its presence through sound only--and thus developed the ability to reach an object presented through sound. Instead, most of the blind children with multiple disabilities presented poor performances on the "reach on sound" protocol and were unable, before 36 months of age, to develop the strategies needed to resolve Fraiberg's "conceptual problem".

Explaining Sad People's Memory Advantage for Faces.
Hills, Peter J; Marquardt, Zoe; Young, Isabel; Goodenough, Imogen
2017-01-01
Sad people recognize faces more accurately than happy people (Hills et al., 2011). We devised four hypotheses for this finding that are tested between in the current study. The four hypotheses are: (1) sad people engage in more expert processing associated with face processing; (2) sad people are motivated to be more accurate than happy people in an attempt to repair their mood; (3) sad people have a defocused attentional strategy that allows more information about a face to be encoded; and (4) sad people scan more of the face than happy people leading to more facial features to be encoded. In Experiment 1, we found that dysphoria (sad mood often associated with depression) was not correlated with the face-inversion effect (a measure of expert processing) nor with response times but was correlated with defocused attention and recognition accuracy. Experiment 2 established that dysphoric participants detected changes made to more facial features than happy participants. In Experiment 3, using eye-tracking we found that sad-induced participants sampled more of the face whilst avoiding the eyes. Experiment 4 showed that sad-induced people demonstrated a smaller own-ethnicity bias. These results indicate that sad people show different attentional allocation to faces than happy and neutral people.

Rahola, T.; Suomela, M.; Illukka, E.; Puhakainen, M.; Pusa, S.
1993-02-01
The atmospheric nuclear weapons tests of the 1950s, '60s and '70s caused global radioactive fallout. After the reactor accident at Chernobyl, radioactive fallout was carried by air streams to most parts of Europe. In 1989-90 radionuclides causing internal contamination were transported to man only via foodchains and no longer via inhalation, as had happened immediately after the accident. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the accident, whole-body counting measurements were performed. Ten different groups of people resident in Finland were measured during 1989-90. Three were local reference groups, two groups consisted of radiation workers, one was a population group presenting the entire country, and four were groups representative of people with special dietary habits. The weighted mean 137 Cs body burden in the population group was 1200 Bq at the end of 1989, and 900 Bq at the end of 1990. The burdens varied from less than 50 Bq to 13 000 Bq in 1990. The measurement data showed that the maximum body burdens were reached in the summer 1987, after which a continuous decrease could be observed. In the groups with special diets, the highest mean Cs-137 body burden in 1990 was found in the Lapp group from Inari. Within this group, the maximum mean body burden, 10 000 Bq, was found in male reindeer herders their body burdens varying from 3000 to 30 000 Bq. The mean effective doses delivered to the population in Finland, estimated by using the measurement data on the population group, was 0.04 mSv in 1989, 0.03 mSv in 1990 and the corresponding committed effective doses were 0.06 mSv and 0.04 mSv, respectively.

Emergence of motor synergy in vertical reaching task via tacit learning.
Hayashibe, Mitsuhiro; Shimoda, Shingo
2013-01-01
The dynamics of multijoint limbs often causes complex dynamic interaction torques which are the inertial effect of other joints motion. It is known that Cerebellum takes important role in a motor learning by developing the internal model. In this paper, we propose a novel computational control paradigm in vertical reaching task which involves the management of interaction torques and gravitational effect. The obtained results demonstrate that the proposed method is valid for acquiring motor synergy in the system with actuation redundancy and resulted in the energy efficient solutions. It is highlighted that the tacit learning in vertical reaching task can bring computational adaptability and optimality with model-free and cost-function-free approach differently from previous studies.

The prevalence of high hyperlipemia is increasing around the world. Our aims are to analyze the relationship of triglyceride (TG) and cholesterol (TC) with indexes of liver function and kidney function, and to develop a prediction model of TG, TC in overweight people. A total of 302 adult healthy subjects and 273 overweight subjects were enrolled in this study. The levels of fasting indexes of TG (fs-TG), TC (fs-TC), blood glucose, liver function, and kidney function were measured and analyzed by correlation analysis and multiple linear regression (MRL). The back propagation artificial neural network (BP-ANN) was applied to develop prediction models of fs-TG and fs-TC. The results showed there was significant difference in biochemical indexes between healthy people and overweight people. The correlation analysis showed fs-TG was related to weight, height, blood glucose, and indexes of liver and kidney function; while fs-TC was correlated with age, indexes of liver function (P < 0.01). The MRL analysis indicated regression equations of fs-TG and fs-TC both had statistic significant (P < 0.01) when included independent indexes. The BP-ANN model of fs-TG reached training goal at 59 epoch, while fs-TC model achieved high prediction accuracy after training 1000 epoch. In conclusions, there was high relationship of fs-TG and fs-TC with weight, height, age, blood glucose, indexes of liver function and kidney function. Based on related variables, the indexes of fs-TG and fs-TC can be predicted by BP-ANN models in overweight people.

Most of us in the science community have been rewarded for our brainpower throughout our lives. Therefore we've learned to rely heavily on our intellectual skills, even though we're clearly much more than disembodied brainiacs. What would happen if we tried to combine our emotions and intellect to communicate with the public? Would it foster deeper connections? NASA's Earth Right Now blog author Laura Faye Tenenbaum noticed that science communication sometimes flat-lines at "Wow," as if that's the only acceptable emotion we can feel. And even though emotions such as anger, frustration disappointment, or joy are messy and uncomfortable, and even though we sometimes worry that showing too much playfulness might prevent our scientific messages from being taken seriously, we decided that writing personal and emotional science stories would be worth a try. In January 2014, Tenenbaum brought her teaching and public speaking experience and her entertainment industry communication knowledge to the Earth Right Now blog. It quickly became one of NASA's most popular, most heavily commented and most shared blogs. We found that, when we combined "feeling" and "thinking," communication thrived and we were able to reach a much wider audience. We learned that to move people, we could begin by tapping into what we were moved by. We saw how lifting the mask of the starchy, nerdy stereotype to show that scientists are real people who experience deep emotions on the job is a best practice for enhancing the public perception of science. As a case study on the effect of using emotional content in communication, the Earth Right Now blog showed not only that it's possible, it's actually beneficial to include complex and authentic emotion in solid science communication.

Approaches to Recruiting 'Hard-To-Reach' Populations into Re-search: A Review of the Literature.
Shaghaghi, Abdolreza; Bhopal, Raj S; Sheikh, Aziz
2011-01-01
'Hard-to-reach' is a term used to describe those sub-groups of the population that may be difficult to reach or involve in research or public health programmes. Application of a single term to call these sub-sections of populations implies a homogeneity within distinct groups, which does not necessarily exist. Different sampling techniques were introduced so far to recruit hard-to-reach populations. In this article, we have reviewed a range of ap-proaches that have been used to widen participation in studies. We performed a Pubmed and Google search for relevant English language articles using the keywords and phrases: (hard-to-reach AND population* OR sampl*), (hidden AND population* OR sample*) and ("hard to reach" AND population* OR sample*) and a consul-tation of the retrieved articles' bibliographies to extract empirical evidence from publications that discussed or examined the use of sampling techniques to recruit hidden or hard-to-reach populations in health studies. Reviewing the literature has identified a range of techniques to recruit hard-to-reach populations, including snowball sampling, respondent-driven sampling (RDS), indigenous field worker sampling (IFWS), facility-based sampling (FBS), targeted sampling (TS), time-location (space) sampling (TLS), conventional cluster sampling (CCS) and capture re-capture sampling (CR). The degree of compliance with a study by a certain 'hard-to-reach' group de-pends on the characteristics of that group, recruitment technique used and the subject of inter-est. Irrespective of potential advantages or limitations of the recruitment techniques reviewed, their successful use depends mainly upon our knowledge about specific characteristics of the target populations. Thus in line with attempts to expand the current boundaries of our know-ledge about recruitment techniques in health studies and their applications in varying situa-tions, we should also focus on possibly all contributing factors which may have an impact on

Young people in adult education
Directory of Open Access Journals (Sweden)
Albert Mrgole
1997-01-01
Full Text Available The increasing number of young people participating in adult education programmes has, in the recent years, raised the question of transfer from regular education system to labour market where a large proportion of young people remain socially marginalized and isolated. Young people in adult education are a special target group; in order to plan educational programmes properly, we need to be familiar with their specific characteristics. The article, on the level of a statistical data outline and its paradoxes, introduces the category of young people in adult education as an impact of system factors, and defines related problems in the register, which - for more thorough understanding - dictates sociologically and anthropologically directed analytical approach. The first effect of this, not solely pedagogical view, is presented in the second part of the article, where Mrgole proposes an analysis of educational needs definition and its dangerous consequences in original planning of educational programmes. The concluding part takes a wider perspective and treats the factors of early school-leaving of young people, taking into consideration direct experience in experimental educational programmes for the young. The article ends with an outline of basic elements which the planners of andragogical educational programmes intended for young people should consider in their planning to achieve effective curricula.

Validity of an Interactive Functional Reach Test.
Galen, Sujay S; Pardo, Vicky; Wyatt, Douglas; Diamond, Andrew; Brodith, Victor; Pavlov, Alex
2015-08-01
Videogaming platforms such as the Microsoft (Redmond, WA) Kinect(®) are increasingly being used in rehabilitation to improve balance performance and mobility. These gaming platforms do not have built-in clinical measures that offer clinically meaningful data. We have now developed software that will enable the Kinect sensor to assess a patient's balance using an interactive functional reach test (I-FRT). The aim of the study was to test the concurrent validity of the I-FRT and to establish the feasibility of implementing the I-FRT in a clinical setting. The concurrent validity of the I-FRT was tested among 20 healthy adults (mean age, 25.8±3.4 years; 14 women). The Functional Reach Test (FRT) was measured simultaneously by both the Kinect sensor using the I-FRT software and the Optotrak Certus(®) 3D motion-capture system (Northern Digital Inc., Waterloo, ON, Canada). The feasibility of implementing the I-FRT in a clinical setting was assessed by performing the I-FRT in 10 participants with mild balance impairments recruited from the outpatient physical therapy clinic (mean age, 55.8±13.5 years; four women) and obtaining their feedback using a NASA Task Load Index (NASA-TLX) questionnaire. There was moderate to good agreement between FRT measures made by the two measurement systems. The greatest agreement between the two measurement system was found with the Kinect sensor placed at a distance of 2.5 m [intraclass correlation coefficient (2,k)=0.786; PNASA/TLX questionnaire. FRT measures made using the Kinect sensor I-FRT software provides a valid clinical measure that can be used with the gaming platforms.

Streamflow investigations on a reach of Hobble Creek near Springville, Utah
Gerner, Steven J.
2017-07-27
The Central Utah Water Conservancy District (CUWCD) is proposing to deliver supplemental flow to Hobble Creek from Strawberry Reservoir through the Mapleton-Springville Lateral pipeline. A substantial portion of the supplemental water is intended to benefit June Sucker recovery and other fish and wildlife along Hobble Creek. The objective of this study was to determine gains or losses of water in a section of Hobble Creek between the Island Dam and the Swenson Dam (the primary study reach) during different seasons and flow conditions.Paired measurements of flow in Hobble Creek were made during June to November 2016, at sites bracketing the primary study reach from site HC3 to HC6. These measurements showed increased streamflow in this reach that ranged from 6.1 cubic feet per second (ft3/s) to 9.3 ft3/s. During August and November, two sets of measurements were made at several locations along the study reach to document baseline conditions, and then an additional amount of water (a pulse of about 9–10 ft3/s) from Strawberry Reservoir through the Mapleton-Springville Lateral pipeline, was added to the reach. During the August 23 measurements, the average change at the upstream site (HC3) relative to the pulse was 9.3 ft3/s, and the average change at the downstream site (HC6) was about 8.4 ft3/s, leaving about 0.9 ft3/s of the additional water unaccounted for at site HC6. However, there was no significant difference between the net streamflow volume at sites HC3 and HC6 associated with the pulse that would indicate water was being lost. During the November 7–9 streamflow measurements, the average change in discharge at site HC3 relative to an increase in flow from the Mapleton-Springville Lateral pipeline (the pulse) was 9.6 ft3/s, and the average change at site HC6 was about 9.8 ft3/s. On the basis of these measurements it appears that the entire amount of the pulse added to the stream at site HC3 was accounted for at site HC6. Additionally, there was no

Peer support programmes use individuals with specific experiences to improve engagement and outcomes among new clients. However, the skills and techniques used to achieve this engagement have not been mapped. This potentially restricts the development and replication of successful peer advocate models of care. This study explored how a group of peer advocates with experience of homelessness, alcohol and drug misuse made and sustained relationships with their client group. For the purposes of this project, the client group were located among a hepatitis C-positive cohort of people who have a history of injecting drug use and homelessness. Five self-selecting advocates gave a narrative interview lasting 40-90 min. These interviews were double transcribed using both thematic analysis and narrative analysis in order to triangulate the data and provide a robust set of findings about the unique skills of peer advocates in creating and sustaining relationships with clients from hard-to-reach populations. Peer advocates build rapport with clients through disclosing personal details about their lives. While this runs counter to assumptions about the need to maintain distance in client-patient relationships, the therapeutic benefits appear to outweigh the potential costs of this engagement. We conclude the therapeutic benefits of self-disclosure between peer advocates and their clients offer a moral grounding for self-disclosure as a means of building relationships with key hard-to-reach populations.

Full Text Available Abstract Background and purpose Providing active assistance to complete desired arm movements is a common technique in upper extremity rehabilitation after stroke. Such active assistance may improve recovery by affecting somatosensory input, motor planning, spasticity or soft tissue properties, but it is labor intensive and has not been validated in controlled trials. The purpose of this study was to investigate the effects of robotically administered active-assistive exercise and compare those with free reaching voluntary exercise in improving arm movement ability after chronic stroke. Methods Nineteen individuals at least one year post-stroke were randomized into one of two groups. One group performed 24 sessions of active-assistive reaching exercise with a simple robotic device, while a second group performed a task-matched amount of unassisted reaching. The main outcome measures were range and speed of supported arm movement, range, straightness and smoothness of unsupported reaching, and the Rancho Los Amigos Functional Test of Upper Extremity Function. Results and discussion There were significant improvements with training for range of motion and velocity of supported reaching, straightness of unsupported reaching, and functional movement ability. These improvements were not significantly different between the two training groups. The group that performed unassisted reaching exercise improved the smoothness of their reaching movements more than the robot-assisted group. Conclusion Improvements with both forms of exercise confirmed that repeated, task-related voluntary activation of the damaged motor system is a key stimulus to motor recovery following chronic stroke. Robotically assisting in reaching successfully improved arm movement ability, although it did not provide any detectable, additional value beyond the movement practice that occurred concurrently with it. The inability to detect any additional value of robot-assisted reaching

Reach-scale land use drives the stress responses of a resident stream fish.
Blevins, Zachary W; Wahl, David H; Suski, Cory D
2014-01-01
Abstract To date, relatively few studies have tried to determine the practicality of using physiological information to help answer complex ecological questions and assist in conservation actions aimed at improving conditions for fish populations. In this study, the physiological stress responses of fish were evaluated in-stream between agricultural and forested stream reaches to determine whether differences in these responses can be used as tools to evaluate conservation actions. Creek chub Semotilus atromaculatus sampled directly from forested and agricultural stream segments did not show differences in a suite of physiological indicators. When given a thermal challenge in the laboratory, creek chub sampled from cooler forested stream reaches had higher cortisol levels and higher metabolic stress responses to thermal challenge than creek chub collected from warmer and more thermally variable agricultural reaches within the same stream. Despite fish from agricultural and forested stream segments having different primary and secondary stress responses, fish were able to maintain homeostasis of other physiological indicators to thermal challenge. These results demonstrate that local habitat conditions within discrete stream reaches may impact the stress responses of resident fish and provide insight into changes in community structure and the ability of tolerant fish species to persist in agricultural areas.

Building machines that learn and think like people.
Lake, Brenden M; Ullman, Tomer D; Tenenbaum, Joshua B; Gershman, Samuel J
2017-01-01
Recent progress in artificial intelligence has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object recognition, video games, and board games, achieving performance that equals or even beats that of humans in some respects. Despite their biological inspiration and performance achievements, these systems differ from human intelligence in crucial ways. We review progress in cognitive science suggesting that truly human-like learning and thinking machines will have to reach beyond current engineering trends in both what they learn and how they learn it. Specifically, we argue that these machines should (1) build causal models of the world that support explanation and understanding, rather than merely solving pattern recognition problems; (2) ground learning in intuitive theories of physics and psychology to support and enrich the knowledge that is learned; and (3) harness compositionality and learning-to-learn to rapidly acquire and generalize knowledge to new tasks and situations. We suggest concrete challenges and promising routes toward these goals that can combine the strengths of recent neural network advances with more structured cognitive models.

Full Text Available Background and Purpose: The modified functional reach test (MFRT is the objective measure for dynamic sitting balance. It quantifies sitting balance in two directions: Forward and lateral reach. So, the purpose of the study was to 1 provide clinical reference value and 2 examine the factors that may influence the anthropometrics measures. Materials and Methods: A total of 200 apparently healthy subjects participated in this descriptive study. All subjects were divided in two groups: Younger (20-39 yr and middle-aged (40-59 yr. After anthropometric measurement, all subjects performed test by reaching forward and lateral with a closed fist while sitting. MFRT was taken with 3 trials with 15 sec break in between. Results: The mean score of the forward and lateral reach of right and left in group 1 was higher compared to group 2. The normative value of forward reach in group 1 was 34.05 ± 9.03 cm; for lateral reach right and left, it was 18.2 ± 5.26 cm and 17.32 ± 5.21 cm, respectively. For group 2, normative values for forward reach, lateral right and left were 25.18 ± 5.71 cm, 14.02 ± 3.98 cm and 13.53 ± 4.25 cm, respectively. There was no significant correlation of forward and lateral reach measures with the anthropometric characteristics in both the groups, except trunk length and BMI in group 1, which was significantly correlated ( P < 0.001. Conclusion: This study provides clinical reference value for younger and middle age group subjects while anthropometrics do not affect performance except trunk length and BMI in younger age group.

Consumption patterns and why people fish

Burger, Joanna
2002-01-01
Recreational and subsistence fishing play major roles in the lives of any people, although their importance in urban areas is often underestimated. There are fish and shellfish consumption advisories in the new York-New Jersey harbor estuary, particularly in the waters of the Newark Bay Complex. This paper examines fishing behavior, consumption patterns, and the reasons that people fish in the Newark Bay Complex. I test the null hypotheses that there are no differences among Asians, Blacks, Hispanics, and whites in consumption patterns for fish and crabs and in the reasons that they fish or crab. Most people either fished or crabbed, but not both. People who fish and crab ate more grams of crab than fish in a given meal; people who crab only consumed more grams of crab at a meal than those who fish only consumed of fish. Although 30% or more of the people who fished and crabbed in the Newark Bay Complex did not eat their self-caught fish or crabs 8-25% of the people ate more than 1500 g/month. Some people angling in the Newark Bay Complex are eating crabs at a rate well over 1500 g/month, and about 70% are eating crabs even though there is a total ban on both harvest and consumption because of the health risks from dioxin. Consumption patterns were negatively correlated with mean income and positively correlated with mean age. Most people rated relaxation and being outdoors the highest reasons or angling, although on an open-ended question they usually listed recreation. There were no ethnic differences in reasons for angling, although other studies have shown ethnic differences in consumption. Obtaining fish or crabs to eat, give away, trade, or sell were rated low, suggesting that consumption advisories fail partly because people are not primarily fishing or food

[Understanding people with Steinert’s disease to better care for them.
Lecordier, Didier; Cartron, Emmanuelle; Jovic, Ljiljana
2017-12-01
the lifestyles of people with myotonic dystrophy type 1 (DM1) are poorly understood and yet their consideration is essential for effective long-term care. The nursing care provided in the reference centers integrates the diversity clinic of this disease in interdisciplinary care, but it is more complicated from a relational point of view. The objective of this qualitative study was to understand the ways of living for a person with DM1, his body and the coping strategies developed. this research in social sciences and nursing is based on a problem of care and is based on an ethnosociological problematization. the aim is to make visible the evolution of the body affected by Steinert’s disease, participating in the construction of the body pattern and the social identity of the person, which allows him to maintain himself in a “normal” daily life as long as possible but can reach limits imposing him radical reorientations in his life. These results are discussed in the light of a framework of analysis based on the four levels of reading of the body proposed by Nicolas Vonarx: the “material body” ; the “capable body”, the “body feeling” and the “knowing/judging body” ; “socializing body” will be proposed to discuss the place the body takes for people living with a DM1 when it comes to living within a normative society.

Hyporheic invertebrate assemblages at reach scale in a Neotropical stream in Brazil.
Mugnai, R; Messana, G; Di Lorenzo, T
2015-11-01
In the Neotropical Region, information concerning hyporheic communities is virtually non-existent. We carried out a sampling survey in the hyporheic zone of the Tijuca River, in the Tijuca National Park, located in the urban area of the city of Rio de Janeiro. Biological samples from the hyporheic zone were collected in three different stream reaches, in June 2012. The main objectives were: 1) to describe the structure of invertebrate assemblages in the hyporheic zone of a neotropical stream; 2) to apply a reach-scale approach in order to investigate spatial patterns of the hyporheic assemblages in relation to hydrology, depth and microhabitat typology. A total of 1460 individuals were collected and identified in 31 taxa belonging to Nematoda, Annelida, Crustacea, Hydrachnidia and Insecta. The class Insecta dominated the upper layer of the hyporheic zone. Copepods were the most abundant taxon among crustaceans and occurred mostly in the upwelling areas of the reaches. The results of this study represent one of the few contributions so far about hyporheic invertebrate assemblages of the Neotropical Region.

Navigational and reaching spaces are known to involve different cognitive strategies and brain networks, whose development in humans is still debated. In fact, high-level spatial processing, including allocentric location encoding, is already available to very young children, but navigational strategies are not mature until late childhood. The Magic Carpet (MC) is a new electronic device translating the traditional Corsi Block-tapping Test (CBT) to navigational space. In this study, the MC and the CBT were used to assess spatial memory for navigation and for reaching, respectively. Our hypothesis was that school-age children would not treat MC stimuli as navigational paths, assimilating them to reaching sequences. Ninety-one healthy children aged 6 to 11 years and 18 adults were enrolled. Overall short-term memory performance (span) on both tests, effects of sequence geometry, and error patterns according to a new classification were studied. Span increased with age on both tests, but relatively more in navigational than in reaching space, particularly in males. Sequence geometry specifically influenced navigation, not reaching. The number of body rotations along the path affected MC performance in children more than in adults, and in women more than in men. Error patterns indicated that navigational sequences were increasingly retained as global paths across development, in contrast to separately stored reaching locations. A sequence of spatial locations can be coded as a navigational path only if a cognitive switch from a reaching mode to a navigation mode occurs. This implies the integration of egocentric and allocentric reference frames, of visual and idiothetic cues, and access to long-term memory. This switch is not yet fulfilled at school age due to immature executive functions. © 2014 John Wiley & Sons Ltd.

The Portuguese background of Ludovicus Nonnius.
Ricon Ferraz, A
1996-01-01
The Portuguese Renaissance was a period of great prestige for national arts and sciences. Innumerable acts concerning the teaching and practice of medicine at the universities and surgical schools of the kingdom were promulgated and contributed to the development of medicine and surgery. However, the 'Físico-Mor' (the principal physician of the country) and the 'Cirurgiäo-Mor' (the principal surgeon of the country) granted certificates to unqualified, non-graduated people. Therefore the medical assistance in Portugal began to decline. On the other hand the Portuguese Parliament did not allow Jews to practise medicine. When the Inquisition was established in Portugal, its extreme religious intolerance led many Jewish physicians to emigrate. Throughout history an important number of these physicians have been highly praised for their humanism, knowledge, pedagogy and with regard to the social repercussions of their medical practising abroad.

Full Text Available This paper focuses on the situation of older people in the information society. In the theoretical part of article phenomena of aging population and information society were described. This paper includes results of research conducted in qualitative strategy. The method of collecting data was biographical method. The method for data processing was qualitative content analysis. In the research 2 older, educationally active people took part. Results of research shows how older people understand the information society and what risk and opportunities they notice in this new reality. Narratives of the respondents indicated that education is of crucial importance for participation in the information society. Older people who take part in lifelong learning cope better with the new reality than people who do not learn. Based on the research results we can point out areas of education which should be development. Moreover, it is visible that educational activity of older people is very important in adaptation to the information society. Narratives of seniors indicate reasons for the lack of educational activity of other seniors. According to this, it can be specified what action should be undertaken to prevent the exclusion of older people in this new reality

Deafblind people, communication, independence, and isolation.
Hersh, Marion
2013-10-01
This paper discusses issues related to communication, independence, and isolation for an understudied group of deaf people who also have visual impairments. The discussion is based on the experiences of 28 deafblind people in 6 different countries, obtained from interviews that were carried out as part of a larger research project on travel issues. However, the similarities in experiences between countries were stronger than the differences. In particular, barriers to communication and inadequate support, with resulting problems of isolation and depression, were found in all the countries. Equally, deafblind people in all the countries were interested in being involved in and contributing to society and supporting other people, particularly through organizations of blind and deafblind people. This runs counter to the tendency to present deafblind and other disabled people purely as recipients of support rather than also as active participants in society. However, there were some differences in the support available in the different countries.

Livestock First Reached Southern Africa in Two Separate Events.
Sadr, Karim
2015-01-01
After several decades of research on the subject, we now know when the first livestock reached southern Africa but the question of how they got there remains a contentious topic. Debate centres on whether they were brought with a large migration of Khoe-speakers who originated from East Africa; or whether the livestock were traded down-the-line among hunter-gatherer communities; or indeed whether there was a long history of diverse small scale population movements in this part of the world, one or more of which 'infiltrated' livestock into southern Africa. A new analysis of the distribution of stone toolkits from a sizeable sample of sub-equatorial African Later Stone Age sites, coupled with existing knowledge of the distribution of the earliest livestock remains and ceramics vessels, has allowed us to isolate two separate infiltration events that brought the first livestock into southern Africa just over 2000 years ago; one infiltration was along the Atlantic seaboard and another entered the middle reaches of the Limpopo River Basin. These findings agree well with the latest results of genetic research which together indicate that multiple, small-scale infiltrations probably were responsible for bringing the first livestock into southern Africa.
