    Full Text Available Abstract Background Behavioural approaches to knowledge translation inform interventions to improve healthcare. However, such approaches often focus on a single behaviour without considering that health professionals perform multiple behaviours in pursuit of multiple goals in a given clinical context. In resource-limited consultations, performing these other goal-directed behaviours may influence optimal performance of a particular evidence-based behaviour. This study aimed to investigate whether a multiple goal-directed behaviour perspective might inform implementation research beyond single-behaviour approaches. Methods We conducted theory-based semi-structured interviews with 12 general medical practitioners (GPs in Scotland on their views regarding two focal clinical behaviours--providing physical activity (PA advice and prescribing to reduce blood pressure (BP to Results Most GPs reported strong intention to prescribe to reduce BP but expressed reasons why they would not. Intention to provide PA advice was variable. Most GPs reported that time constraints and patient preference detrimentally affected their control over providing PA advice and prescribing to reduce BP, respectively. Most GPs perceived many of their other goal-directed behaviours as interfering with providing PA advice, while fewer GPs reported goal-directed behaviours that interfere with prescribing to reduce BP. Providing PA advice and prescribing to reduce BP were perceived to be facilitated by similar diabetes-related behaviours (e.g., discussing cholesterol. While providing PA advice was perceived to be mainly facilitated by providing other lifestyle-related clinical advice (e.g., talking about weight, BP prescribing was reported as facilitated by pursuing ongoing standard consultation-related goals (e.g., clearly structuring the consultation. Conclusion GPs readily relate their other goal-directed behaviours with having a facilitating and interfering influence on their

    The strategic importance of ecosystem service valuation as an operational basis for policy decisions on natural restoration has been increasingly recognized in order to align the provision of ecosystem services with the expectation of human society. The contingent valuation method (CVM) is widely used to quantify various ecosystem services. However, two areas of concern arise: (1) whether people value specific functional ecosystem services and overlook some intrinsic aspects of natural restoration, and (2) whether people understand the temporal dimension of ecosystem services and payment schedules given in the contingent scenarios. Using a peri-urban riparian meadow restoration project in Flanders, Belgium as a case, we explored the impacts of residents' perceived importance of various ecosystem services and stated financial constraints on their willingness-to-pay for the proposed restoration project employing the CVM. The results indicated that people tended to value all the benefits of riparian ecosystem restoration concurrently, although they accorded different importances to each individual category of ecosystem services. A longer payment scheme can help the respondents to think more about the flow of ecosystem services into future generations. A weak temporal embedding effect can be detected, which might be attributed to respondents' concern about current financial constraints, rather than financial bindings associated with their income and perceived future financial constraints. This demonstrates the multidimensionality of respondents' financial concerns in CV. This study sheds light on refining future CV studies, especially with regard to public expectation of ecosystem services and the temporal dimension of ecosystem services and payment schedules.

    Research shows that implicit motives influence social relationships. However, little is known about their role in fatherhood and, particularly, how men experience their paternal role. Therefore, this study examined the association of implicit motives and fathers' perceived constraint due to fatherhood. Furthermore, we explored their relation to fathers' life satisfaction. Participants were fathers with biological children ( N = 276). They were asked to write picture stories, which were then coded for implicit affiliation and power motives. Perceived constraint and life satisfaction were assessed on a visual analog scale. A higher implicit need for affiliation was significantly associated with lower perceived constraint, whereas the implicit need for power had the opposite effect. Perceived constraint had a negative influence on life satisfaction. Structural equation modeling revealed significant indirect effects of implicit affiliation and power motives on life satisfaction mediated by perceived constraint. Our findings indicate that men with a higher implicit need for affiliation experience less constraint due to fatherhood, resulting in higher life satisfaction. The implicit need for power, however, results in more perceived constraint and is related to decreased life satisfaction.

  10. Do older adults perceive postural constraints for reach estimation?

    Science.gov (United States)

    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.

    Previous studies primarily fo c used on how disease- and treatment-related variables affect cancer survivors' sleep quality. Little is known about the impact of the psychosocial factors on their sleep quality. Social constraints are perceived negative social interactions inhibiting one's disclosure. This study examined the association between social constraints and Chinese American breast cancer survivors' (BCS) sleep quality and tested perceived stress as a mediator explaining the association. Chinese American BCS (n = 94) were recruited from Southern California. Participants' social constraints, perceived stress, and sleep quality were measured in a questionnaire package. Social constraints were associated with higher perceived stress (r = 0.32, p = .002) and poorer sleep quality (r = 0.33, p stress was associated with poorer sleep quality (r = 0.47, p social constraints to poor sleep quality (indicated by the Pittsburgh Sleep Quality Index; PSQI) via perceived stress was significant (β = 0.20; 95% confidence intervals (CI) = 0.06, 0.40). The path coefficient for direct effect from social constraints to PSQI significantly dropped from β = 0.32 (95% CI = 0.11, 0.51) to β = 0.13 (95% CI = -0.12, 0.35) after considering perceived stress as a mediator, suggesting a mediation effect. This study implied that social constraints may worsen sleep quality among Chinese American BCS through increasing perceived stress. Interventions to reduce social constraints and perceived stress may improve sleep quality.

    Gabbard, Carl; Caçola, Priscila; Cordova, Alberto

    2009-06-01

    A form of action representation of developmental interest is reach estimation-the perceptual and cognitive judgment of whether an object is within or out of reach. A common observation among children is overestimation, which, speculatively, has been linked to perceived motor competence (PMC). The authors examined the PMC effect on reachability among 7-, 9-, and 11-year-old children. The authors predicted that with higher PMC, participants would display greater overestimation and that this outcome would show a developmental trend with younger children displaying greater overestimation complementing higher PMC scores. Results revealed no age differences in total error for reach, and all age groups overestimated. Regarding PMC, the 7-year-old childrens' scores were significantly higher than those of their older counterparts. However, relation analyses revealed no support for the idea that PMC was significantly associated with reachability. The findings suggested that a general measure of PMC is not a good predictor of childrens' action planning through reach estimation. Furthermore, if PMC in some form is a psychological constraint, future studies should be tied to context-specific measures of perceived abilities in relation to the specificity of the task.

  18. Do children perceive postural constraints when estimating reach or action planning?

    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.

  1. The impact of financial constraints and incentives on professional autonomy.

    2003-01-01

    General practice has been the subject of extensive reforms over the 1990s in Australia as elsewhere. Reforms have attempted to improve quality and contain the overall cost of health care, and have often been seen as reducing the autonomy of medical professionals. This paper examines the impact of financial constraints and incentives introduced during the 1990s on Australian GPs' perceptions of autonomy. An existing seven component definition of autonomy and six themes that emerged from reviewing publications were used to construct focus group questions. A total of 25 GPs participated in four focus groups. Those who participated believe that their financial autonomy has been diminished by policy changes and consumer expectations. They also perceive that their ability to control clinical decisions, which they regard as the most important aspect of professional autonomy, has been reduced along with financial autonomy. Organized medicine in Australia sees financial accountability and clinical decision making as polar opposites, and has continued to argue that fee-for-service payment is the only appropriate method of remuneration, despite increasing evidence that this does not guarantee clinical autonomy. Major changes to the financing of general practice in Australia are required to address the concerns of GPs, governments and patients.

  2. Perceived agricultural runoff impact on drinking water.

    2014-09-01

    Agricultural runoff into surface water is a problem in Australia, as it is in arguably all agriculturally active countries. While farm practices and resource management measures are employed to reduce downstream effects, they are often either technically insufficient or practically unsustainable. Therefore, consumers may still be exposed to agrichemicals whenever they turn on the tap. For rural residents surrounded by agriculture, the link between agriculture and water quality is easy to make and thus informed decisions about water consumption are possible. Urban residents, however, are removed from agricultural activity and indeed drinking water sources. Urban and rural residents were interviewed to identify perceptions of agriculture's impact on drinking water. Rural residents thought agriculture could impact their water quality and, in many cases, actively avoided it, often preferring tank to surface water sources. Urban residents generally did not perceive agriculture to pose health risks to their drinking water. Although there are more agricultural contaminants recognised in the latest Australian Drinking Water Guidelines than previously, we argue this is insufficient to enhance consumer protection. Health authorities may better serve the public by improving their proactivity and providing communities and water utilities with the capacity to effectively monitor and address agricultural runoff.

  3. Experimental constraints on impact-induced winds

    A new class of wind streaks on Mars uniquely associated with impact craters is most clearly detected in nighttime thermal infrared imaging. Thermally bright streaks radiate from some well-preserved impact craters and are related to the impact process. Using laboratory experiments performed at the NASA Ames Vertical Gun Range, we test the hypothesis that these streaks are formed from either the winds within an air-blast or winds set up by expanding impact vapor interacting with the atmosphere. The experiments use a variety of tracers and instruments to document three interrelated processes occurring in the impact of a Pyrex projectile into an easily vaporized powdered dolomite target: (1) a surface roughening spreading outward from the impact point, (2) an expanding vapor plume, and (3) outward winds made visible by dust trails from vertically placed, dusty pipe cleaners. The clear connection between the surface roughening, vapor expansion, and outward winds implicate an expanding vapor interacting with the atmosphere as the controlling process.

    Gunilla Ström

    Full Text Available Keeping pigs in urban and peri-urban areas may not only provide many benefits for the urban households, but may also be challenging and a potential health hazard. The aim of this cross-sectional study was to describe household characteristics and to evaluate perceived benefits and constraints among pig-keepers in the urban and peri-urban areas of Phnom Penh, Cambodia. The study included 204 households and a structured questionnaire was used to interview the household member responsible for taking care of the pigs. Descriptive analyses showed that most households kept between 5 and 15 pigs and that all households kept their pigs in confinement. About 97% of the households owned the pigs themselves and the pigs were generally managed by female household members (43%. Pigs were mainly kept for commercial purposes and more than 60% of the households stated that income from pig-keeping was the main or one of the main sources of revenue for the household. More than 82% reported that they had experienced disease outbreaks among their pigs during the past three years and disease outbreaks were more commonly reported in households with lower socio-economic position (P = 0.025. Disease outbreaks were considered one of the main constraints, along with expensive feed and low payment prices for the slaughter pigs, but few households considered sanitary or other public health issues problematic. Thus, pig-keeping makes an important contribution to the livelihoods of urban and peri-urban households, but many households face external constraints on their production, such as diseases and low revenues, which may have a negative impact on their livelihoods.

  8. Synchronization of impacting mechanical systems with a single constraint

    2018-01-01

    This paper addresses the synchronization problem of mechanical systems subjected to a single geometric unilateral constraint. The impacts of the individual systems, induced by the unilateral constraint, generally do not coincide even if the solutions are arbitrarily 'close' to each other. The mismatch in the impact time instants demands a careful choice of the distance function to allow for an intuitively correct comparison of the discontinuous solutions resulting from the impacts. We propose a distance function induced by the quotient metric, which is based on an equivalence relation using the impact map. The distance function obtained in this way is continuous in time when evaluated along jumping solutions. The property of maximal monotonicity, which is fulfilled by most commonly used impact laws, is used to significantly reduce the complexity of the distance function. Based on the simplified distance function, a Lyapunov function is constructed to investigate the synchronization problem for two identical one-dimensional mechanical systems. Sufficient conditions for the uncoupled individual systems are provided under which local synchronization is guaranteed. Furthermore, we present an interaction law which ensures global synchronization, also in the presence of grazing trajectories and accumulation points (Zeno behavior). The results are illustrated using numerical examples of a 1-DOF mechanical impact oscillator which serves as stepping stone in the direction of more general systems.

    1992-01-01

    This paper describes methods for evaluating perception-based economic impacts resulting from siting hazardous waste facilities. Socioeconomic impact analysis has devoted increasing attention to the potential implications of changed public perceptions of risk due to an activity or situation. This contrasts with traditional socioecconomic impact analysis, which has been limited to measuring direct and indirect consequences of activities, e.g., the employment effects of placing a military base in a specified location. Approaches to estimating economic impacts due to changes in public perceptions are ex ante or ex post. The former predict impacts prior to the construction and operation of a facility, while the later is based on impacts that become evident only when the facility is up and running. The theoretical foundations and practical requirements for demonstrating impacts, resulting from the siting of a hazardous facility are described. The theoretical rationale supporting the study of perceived risk research is presented along with discussion of problems that arise in demonstrating the existence and measuring the quantitative importance of economic impacts due to changes in perceived risk. The high-level nuclear waste facility being considered in Nevada is presented as an example in which there is potential for impacts, but where the link between perceived risk and economic conditions has not yet been developed

    2003-06-01

    Functional facial deformities are usually described as those that impair respiration, eating, hearing, or speech. Yet facial scars and cutaneous deformities have a significant negative effect on social functionality that has been poorly documented in the scientific literature. Insurance companies are declining payments for reconstructive surgical procedures for facial deformities caused by congenital disabilities and after cancer or trauma operations that do not affect mechanical facial activity. The purpose of this study was to establish a large, sample-based evaluation of the perceived social functioning, interpersonal characteristics, and employability indices for a range of facial appearances (normal and abnormal). Adult volunteer evaluators (n = 210) provided their subjective perceptions based on facial physical appearance, and an analysis of the consequences of facial deformity on parameters of preferential treatment was performed. A two-group comparative research design rated the differences among 10 examples of digitally altered facial photographs of actual patients among various age and ethnic groups with "normal" and "abnormal" congenital deformities or posttrauma scars. Photographs of adult patients with observable congenital and posttraumatic deformities (abnormal) were digitally retouched to eliminate the stigmatic defects (normal). The normal and abnormal photographs of identical patients were evaluated by the large sample study group on nine parameters of social functioning, such as honesty, employability, attractiveness, and effectiveness, using a visual analogue rating scale. Patients with abnormal facial characteristics were rated as significantly less honest (p = 0.007), less employable (p = 0.001), less trustworthy (p = 0.01), less optimistic (p = 0.001), less effective (p = 0.02), less capable (p = 0.002), less intelligent (p = 0.03), less popular (p = 0.001), and less attractive (p = 0.001) than were the same patients with normal facial

  13. Perceived and calculated health risks: do the impacts differ

    Payne, B.A.; Williams, R.G.

    1986-01-01

    In many cases of radioactive and hazardous waste management, some members of the general public perceive that human health risks associated with the wastes are higher than the calculated risks. Calculated risks are projections that have been derived from models, and it is these risks that are usually used as the basis for waste management. However, for various reasons, the calculated risks are often considered by the public as too low or inappropriate. The reasons that calculated risks are not perceived as accurate and the factors that affect these perceptions are explored in this paper. Also discussed are the impacts related to the perceived and calculated health risks: what they are, and if and how they differ. The kinds of potential impacts examined are health effects, land value changes, and social, transportation, and economic effects. The paper concludes with a discussion of the implications of incorporating these different risk perspectives in decisions on waste management

The guidance law is first developed with the prior-assumption of a stationary target, which is followed by the practical extension to a maneuvering target scenario. To derive the closed-form guidance law, the trajectory reshaping technique is utilized and it results in defining a specific polynomial function with two unknown coefficients. These coefficients are determined to satisfy the impact time and angle constraints as well as the zero miss distance. Furthermore, the proposed guidance law has three additional guidance gains as design parameters which make it possible to adjust the guided trajectory according to the operational conditions and missile’s capability. Numerical simulations are presented to validate the effectiveness of the proposed guidance law.

    As Federal waste Management Systems (FWMS) receiving facilities become available, the US Department of Energy (DOE) intends to begin accepting spent nuclear fuel from US utilities for eventual permanent disposal. Transporting the radioactive spent fuel to the repository will require development of a complex network of equipment, services, and operations personnel that will comprise the Transportation Operations System. This paper identifies and discusses, in a qualitative manner, the key reactor facility constraints that will eventually need to be assessed in detail on a site-specific basis to guide the development of the FWMS transportation cask fleet. This evaluation of constraints is needed to assess their impact on the size, composition, availability, and use of the cask fleet and to assist in the development of the transportation system support facilities such as a cask maintenance facility. Such assessment will also be needed to support decisions on modifying shipping facilities (i.e., reactors), identification and design of interface hardware, and on the designs of receiving facilities

    To assess the frequency of use by and perceived impact of various educational technologies on student pharmacists. Data were obtained using a validated, Web-based survey instrument designed to evaluate the frequency of use and impact on learning of various technologies used in educating first-, second-, and third-year student pharmacists. Basic demographic data also were collected and analyzed. The majority (89.4%) of the 179 respondents were comfortable with the technology used in the academic program. The most frequently used technologies for educational purposes were in class electronic presentations, course materials posted on the school Web site, and e-mail. The technologies cited as having the most beneficial impact on learning were course materials posted on the Web site and in-class electronic presentations, and those cited as most detrimental were video-teleconferencing and online testing. Compared to the course textbook, students reported more frequent use of technologies such as electronic course materials, presentations, digital lecture recordings, e-mail, and hand-held devices. Because students' opinions of educational technologies varied, colleges and schools should incorporate educational technologies that students frequently use and that positively impact learning.

    Consuming a healthy diet forms an important component of diabetes management; however, adhering to a healthy diet is challenging. Dietary behaviour is often guided by socio-cultural, environmental and emotional factors, and not necessarily by physical and nutritional needs. This study explored Nepalese patients' perceptions of the impact of diet, diet management requirement for diabetes and how Nepalese food culture in particular influenced diet management. Interviews were conducted with Nepalese participants with type 2 diabetes in Sydney and Kathmandu; and data was thematically analysed. Diet was recognized as a cause of, and a key treatment modality, in diabetes. Besides doctors, participants in Nepal received a large amount of dietary information from the community. Dietary changes formed a major component of lifestyle modifications adopted after diagnosis, and mostly consisted of removal of foods with added sugar and foods with high total sugar content from the diet, and a reduction in overall quantity of foods consumed. Perceived dietary restriction requirements created social and emotional discomfort to patients. Most participants perceived the Nepalese food culture as a barrier to effective diet management. Meals high in carbohydrates, limited food choices, and food preparation methods were identified as barriers, particularly in Nepal. In Australia, participants reported greater availability and easier access to appropriate food, and healthier cooking options. The socio-cultural aspects of food behaviour, mainly, food practices during social events were identified as significant barriers. Although diet was acknowledged as an important component of diabetes care, and most adopted changes in their diet post-diagnosis, effective and sustained changes were difficult to achieve. Future public health campaigns and education strategies should focus on improving diet knowledge, awareness of food options for diabetes, and effective dietary management. Copyright

    We aimed to assess perceptions of the effects of the 80-hour workweek (80hWW) restriction on patient care, education, and resident quality of life. In April 2007, attending surgeons and residents in nine surgical specialties at our institution were surveyed. Respondents were categorized into three groups: (1) attending surgeons; (2) residents beginning their training before the 80hWW implementation (ResBefore); and (3) residents beginning training after the 80hWW implementation (ResAfter). Differences between groups were assessed with univariate analysis. The overall response rate was 57%. A minority in all three groups ( or =84%) agreed that midlevel providers were now critical to successfully deliver health care (P = 0.40). Fewer attending surgeons (21%) and ResBefore (29%) perceived improvements in education compared with ResAfter (68%; P work-life balance for residents (attending surgeons [85%], ResBefore [71%], and ResAfter [92%]; P = 0.008), but 76% of attending surgeons reported decreased job satisfaction. We showed a discrepancy between perceptions of attending surgeons and residents regarding the effect of the 80hWW on patient care and surgical education. Quality of life was improved for residents but not for attending surgeons. The impact of the 80hWW on patient care and surgical education needs to be quantified.

    An emerging nursing education trend is to utilize simulated learning experiences as a means to optimize competency and decision making skills. The purpose of this study was to examine differences in students' perception of clinical decision making and clinical decision making-related self-confidence and anxiety based on the sequence (order) in which they participated in a block of simulated versus hospital-based learning experiences. A quasi-experimental crossover design was used. Between and within group differences were found relative to self-confidence with the decision making process. When comparing groups, at baseline the simulation followed by hospital group had significantly higher self-confidence scores, however, at 14-weeks both groups were not significantly different. Significant within group differences were found in the simulation followed by hospital group only, demonstrating a significant decrease in clinical decision making related anxiety across the semester. Finally, there were no significant difference in; perceived clinical decision making within or between the groups at the two measurement points. Preliminary findings suggest that simulated learning experiences can be offered with alternating sequences without impacting the process, anxiety or confidence with clinical decision making. This study provides beginning evidence to guide curriculum development and allow flexibility based on student needs and available resources. Copyright © 2017. Published by Elsevier Ltd.

  11. Impact of carbon constraint on the European electricity sector

    International Nuclear Information System (INIS)

    Stankeviciute, Loreta

    2010-01-01

    Two sets of factors will be decisive for the future evolution of European electricity sector: on the one hand, the necessity of new wave of investments for the renewal and the expansion of production capacities and, on the other hand, the emergency and the reinforcement of greenhouse gas emissions (GHG) constraints imposed by European policies and directives. The general idea of thesis is that European Emissions Trading system (ETS) is the instrument that can facilitate the decarbonization of European electricity system. However, the necessary conditions ought to be brought together in the context of liberalisation in terms of risk management, market architecture and setting up of the complementary public policy instruments, in order for the carbon price signal to be effective. The purpose of the thesis is to provide details on these conditions and to examine the potentials scenarios for the evolution of European electricity production mix under the carbon constraint. The introduction of liberalisation in the electricity industry conditions significantly the investment choice. The analysis of theoretical market model allows demonstrating organisational inadequacy for developing an optimal technological mix and for adapting to long-term issues due to the extreme difficulty of interpreting the price signals. Indeed, the logic of a market and a concurrence disadvantages the investments in capital-intensive technologies, even though some of them less polluting like renewable energies, nuclear, hydraulic and thermal technologies integrating carbon capture and sequestration (CCS). In face of numerous uncertainties, the role of long-term risk management becomes therefore crucial. The employment of transaction cost theory allows studying the combinations of vertical arrangements that remain necessary in order to manage the risk and to facilitate the investments (e.g. vertical integration). The introduction of ETS overlaps with the market risks inherent to liberalisation

    1996-02-01

    A new method for mitigating unexpected impact of a redundant manipulator with an object in its environment is presented. Kinematic constraints are utilized with the recently developed method known as Full Space Parameterization (FSP). System performance criterion and constraints are changed at impact to return the end effector to the point of impact and halt the arm. Since large joint accelerations could occur as the manipulator is halted, joint acceleration bounds are imposed to simulate physical actuator limitations. Simulation results are presented for the case of a simple redundant planar manipulator.

  15. The Impact of Geometrical Constraints on Collisionless Magnetic Reconnection

    2012-01-01

    One of the most often cited features associated with collisionless magnetic reconnection is a Hall-type magnetic field, which leads, in antiparallel geometries, to a quadrupolar magnetic field signature. The combination of this out of plane magnetic field with the reconnection in-plane magnetic field leads to angling of magnetic flux tubes out of the plane defined by the incoming magnetic flux. Because it is propagated by Whistler waves, the quadrupolar field can extend over large distances in relatively short amounts of time - in fact, it will extend to the boundary of any modeling domain. In reality, however, the surrounding plasma and magnetic field geometry, defined, for example, by the overall solar wind flow, will in practice limit the extend over which a flux tube can be angled out of the main plain. This poses the question to what extent geometric constraints limit or control the reconnection process and this is the question investigated in this presentation. The investigation will involve a comparison of calculations, where open boundary conditions are set up to mimic either free or constrained geometries. We will compare momentum transport, the geometry of the reconnection regions, and the acceleration if ions and electrons to provide the current sheet in the outflow jet.

    2015-01-01

    Healthcare service quality studies primarily examine the relationships between patients' perceived quality and satisfaction with healthcare services, clinical effectiveness, service use, recommendations and value for money. These studies suggest that patient-independent quality dimensions (structure, process and outcome) are antecedents to quality. The purpose of this paper is to propose an alternative by looking at the relationship between hospital atmosphere and healthcare quality with perceived outcome. Data were collected from Finland, India, Nigeria and the People's Republic of China. Regression analysis used perceived outcome as the dependent variable and atmosphere and healthcare service quality as independent variables. Findings - Results showed that atmosphere and healthcare service quality have a statistically significant relationship with patient perceived outcomes. The sample size was small and the sampling units were selected on convenience; thus, caution must be exercised in generalizing the findings. The study determined that service quality and atmosphere are considered significant for developing and developed nations. This result could have significant implications for policy makers and service providers developing healthcare quality and hospital atmosphere. Studies concentrate on healthcare outcome primarily regarding population health status, mortality, morbidity, customer satisfaction, loyalty, quality of life, customer behavior and consumption. However, the study exposes how patients perceive their health after treatment. Furthermore, the authors develop the healthcare service literature by considering atmosphere and perceived outcome.

  17. Exploring the impact of constraints in quantum optimal control through a kinematic formulation

    Donovan, Ashley; Beltrani, Vincent; Rabitz, Herschel

    2013-01-01

    Highlights: • This work lays a foundation for studying constraints in quantum control simulations. • The underlying quantum control landscape in the presence of constraints is explored. • Constrained controls can encounter suboptimal traps in the landscape. • The controls are kinematic stand-ins for dynamic time-dependent controls. • A method is developed to transfer between constrained kinematic and dynamic controls. - Abstract: The control of quantum dynamics with tailored laser fields is finding growing experimental success. In practice, experiments will be subject to constraints on the controls that may prevent full optimization of the objective. A framework is presented for systematically investigating the impact of constraints in quantum optimal control simulations using a two-stage process starting with simple time-independent kinematic controls, which act as stand-ins for the traditional dynamic controls. The objective is a state-to-state transition probability, and constraints are introduced by restricting the kinematic control variables during optimization. As a second stage, the means to map from kinematic to dynamic controls is presented, thus enabling a simplified overall procedure for exploring how limited resources affect the ability to optimize the objective. A demonstration of the impact of imposing several types of kinematic constraints is investigated, thereby offering insight into constrained quantum controls

    To explore the stress related to motherhood and its perceived impact on adherence to therapy in women with cystic fibrosis (CF). Cross-sectional study with a purpose-designed questionnaire. 46/73 eligible women were enrolled and 38 returned the questionnaire. Mean age of mothers was 33.8 y  ± 7.1 y, mean age of firstborn child was 6.9 y  ± 5.7 y. Nine women had more than one biological child. 18 mothers (47%) were currently employed, 12 of whom worked 19 to 30 hours per week and none full-time. There were mothers who reported a detrimental effect on adherence (time constraints 38%; intentional nonadherence 42%), and mothers who reported that adherence had actually improved (29%). Both of these effects were related to daily CF therapy at home. By contrast, i. v. antibiotic therapy was less impaired by role strains, mainly due to home i. v. therapy being an alternative and/or due to intensive social support (husband, parents). Participants clearly addressed the importance of adherence and the need for adequate self-management in narrative comments. Motherhood may improve adherence to CF therapy as well as it may affect it negatively. Health caregivers are well-advised to address a possible detrimental effect, proactively. © Georg Thieme Verlag KG Stuttgart · New York.

    To examine attitudes, priorities, and constraints pertaining to herd reproductive management perceived by farmers managing seasonal-calving, pasture-based dairy herds in four regions of New Zealand, and to explore how these varied with demographic and biophysical factors. Key decision makers (KDM) on 133 dairy herds in four dairy regions (Waikato, Taranaki, and north and south Canterbury) were interviewed between May and July 2009. They were asked to provide demographic and biophysical data about the farm, and to rate their attitude in relation to their own personality traits, management issues and priorities, and likely constraints affecting reproductive performance in their herds. Associations between demographic factors and attitudes, priorities and constraints were analysed using univariable and multivariable proportional-odds regression models. Farms in the regions studied in the South Island were larger, had larger herds and more staff than farms in the regions studied in the North Island. The farms in the South Island were more likely to be owned by a corporation, managed by younger people or people who had more education, and the herds were more likely to be fed a higher percentage of supplementary feed. The majority of KDM rated the current genetics, milksolids performance and reproductive performance of their herds as high or very high, and >70% believed that the reproductive performance had remained the same or improved over the preceding 3 years. Despite this, improving reproductive performance was the most highly rated priority for the next 3 years. The constraints considered most likely to have affected reproductive performance in the last 2 years were anoestrous cows, protracted calving periods, and low body condition scores; those considered least likely were artificial breeding and heat detection. Of the variables examined related to attitudes, priorities and likely constraints, there were significant differences between region for 10/40, and with

    2018-03-01

    We provide a fast method for computing constraints on impactor pre-impact orbits, applying this to the late giant impacts in the Solar system. These constraints can be used to make quick, broad comparisons of different collision scenarios, identifying some immediately as low-probability events, and narrowing the parameter space in which to target follow-up studies with expensive N-body simulations. We benchmark our parameter space predictions, finding good agreement with existing N-body studies for the Moon. We suggest that high-velocity impact scenarios in the inner Solar system, including all currently proposed single impact scenarios for the formation of Mercury, should be disfavoured. This leaves a multiple hit-and-run scenario as the most probable currently proposed for the formation of Mercury.

    As indoor air quality complaints cannot be explained satisfactorily and building materials can be a major source of indoor air pollution, we hypothesized that emissions from building materials perceived as unfamiliar or annoying odors may contribute to such complaints. To test this hypothesis....... Similarly, OA was increased significantly for most organic  samples, but not the synthetic  ones. The major effect is probably that OA is increased when the panel is given information about the odor source....

    Obstetric anal sphincter injury is common but the effect on body image is unreported. The aim of this study was to explore patient perceived changes in body image and other psychological aspects in women attending a perineal follow-up clinic. This retrospective study analysed women's responses to a self-reported questionnaire. Consecutive women with anal sphincter injury who attended a United Kingdom Maternity Hospital perineal follow-up clinic between January 1999 and January 2012 were identified and the records obtained and reviewed. Multivariate regression analyses were performed to examine variables influencing self-reported change in body image. Questionnaires and operation notes were analysed from 422 women who attended at a median of four months after delivery. 222 (53%) reported a change in body image with 80 (19%) reporting lower self-esteem and 75 (18%) a change in their personality due to the change in body image. 248 (59%) perceived an anatomical change due to the delivery. Factors associated with increased likelihood of reporting a change in body image were reporting a perceived change in anatomy due to the delivery, adjusted OR 6.11 (3.56-10.49), anal incontinence, OR 1.97 (1.16-3.36), and delivery by forceps, OR 2.59 (1.23-5.43). This is the first study to quantify body image changes in women after anal sphincter injury sustained in childbirth. These were found to be very common, affecting up to 50% of women. The study has several limitations but it does highlight the significant psychosocial problems of negative self-esteem and personality changes associated with a perceived change in body image that has not previously been reported. It also outlines the further research questions that need to be addressed. Copyright © 2017 Elsevier B.V. All rights reserved.

  11. Impact of leaf motion constraints on IMAT plan quality, deliver accuracy, and efficiency

    2011-01-01

    Purpose: Intensity modulated arc therapy (IMAT) is a radiation therapy delivery technique that combines the efficiency of arc based delivery with the dose painting capabilities of intensity modulated radiation therapy (IMRT). A key challenge in developing robust inverse planning solutions for IMAT is the need to account for the connectivity of the beam shapes as the gantry rotates from one beam angle to the next. To overcome this challenge, inverse planning solutions typically impose a leaf motion constraint that defines the maximum distance a multileaf collimator (MLC) leaf can travel between adjacent control points. The leaf motion constraint ensures the deliverability of the optimized plan, but it also impacts the plan quality, the delivery accuracy, and the delivery efficiency. In this work, the authors have studied leaf motion constraints in detail and have developed recommendations for optimizing the balance between plan quality and delivery efficiency. Methods: Two steps were used to generate optimized IMAT treatment plans. The first was the direct machine parameter optimization (DMPO) inverse planning module in the Pinnacle 3 planning system. Then, a home-grown arc sequencer was applied to convert the optimized intensity maps into deliverable IMAT arcs. IMAT leaf motion constraints were imposed using limits of between 1 and 30 mm/deg. Dose distributions were calculated using the convolution/superposition algorithm in the Pinnacle 3 planning system. The IMAT plan dose calculation accuracy was examined using a finer sampling calculation and the quality assurance verification. All plans were delivered on an Elekta Synergy with an 80-leaf MLC and were verified using an IBA MatriXX 2D ion chamber array inserted in a MultiCube solid water phantom. Results: The use of a more restrictive leaf motion constraint (less than 1-2 mm/deg) results in inferior plan quality. A less restrictive leaf motion constraint (greater than 5 mm/deg) results in improved plan quality

  13. Optimal Ordering and Pricing Policies for Seasonal Products: Impacts of Demand Uncertainty and Capital Constraint

    Directory of Open Access Journals (Sweden)

    Jinzhao Shi

    2016-01-01

    Full Text Available With a stochastic price-dependent market demand, this paper investigates how demand uncertainty and capital constraint affect retailer’s integrated ordering and pricing policies towards seasonal products. The retailer with capital constraint is normalized to be with zero capital endowment while it can be financed by an external bank. The problems are studied under a low and high demand uncertainty scenario, respectively. Results show that when demand uncertainty level is relatively low, the retailer faced with demand uncertainty always sets a lower price than the riskless one, while its order quantity may be smaller or larger than the riskless retailer’s which depends on the level of market size. When adding a capital constraint, the retailer will strictly prefer a higher price but smaller quantity policy. However, in a high demand uncertainty scenario, the impacts are more intricate. The retailer faced with demand uncertainty will always order a larger quantity than the riskless one if demand uncertainty level is high enough (above a critical value, while the capital-constrained retailer is likely to set a lower price than the well-funded one when demand uncertainty level falls within a specific interval. Therefore, it can be further concluded that the impact of capital constraint on the retailer’s pricing decision can be influenced by different demand uncertainty levels.

    Anthropogenic debris contaminates marine habitats globally, leading to several perceived ecological impacts. Here, we critically and systematically review the literature regarding impacts of debris from several scientific fields to understand the weight of evidence regarding the ecological impacts of marine debris. We quantified perceived and demonstrated impacts across several levels of biological organization that make up the ecosystem and found 366 perceived threats of debris across all levels. Two hundred and ninety-six of these perceived threats were tested, 83% of which were demonstrated. The majority (82%) of demonstrated impacts were due to plastic, relative to other materials (e.g., metals, glass) and largely (89%) at suborganismal levels (e.g., molecular, cellular, tissue). The remaining impacts, demonstrated at higher levels of organization (i.e., death to individual organisms, changes in assemblages), were largely due to plastic marine debris (> 1 mm; e.g., rope, straws, and fragments). Thus, we show evidence of ecological impacts from marine debris, but conclude that the quantity and quality of research requires improvement to allow the risk of ecological impacts of marine debris to be determined with precision. Still, our systematic review suggests that sufficient evidence exists for decision makers to begin to mitigate problematic plastic debris now, to avoid risk of irreversible harm.

    Westrick, Salisa C; Mount, Jeanine K

    2009-02-01

    An in-house immunization service in which staff pharmacists administer vaccines was conceptualized as an innovation. Prior to making adoption decisions, community pharmacies evaluated characteristics of in-house immunization services. This study examined the impact of three specific characteristics (perceived benefit, perceived compatibility and perceived complexity) of in-house immunization services on community pharmacies' adoption decisions. A multi-stage mixed-mode survey design was used to collect data from key informants of community pharmacies in Washington State, USA. Key informants included pharmacy managers or pharmacists-on-duty who were able to answer questions related to immunization activities in their pharmacies. Perceived characteristics of in-house immunization services and pharmacy adoption decisions were measured in 2004 and in 2006-2007, respectively. Each perceived characteristic individually predicted adoption of in-house immunization services. When all three characteristics were included in logistic regression, perceived benefit was the only significant predictor of in-house immunization service adoption. Appropriate strategies, particularly promoting the benefit of in-house immunization services, should be implemented. The proposed model and findings may be applicable to other pharmacy-based innovative practices or other public health initiatives. We recommend that organizational leaders, researchers and practitioners consider the impact of perceived benefit and incorporate it when they design strategies to foster adoption of innovative practices. Doing this may increase the number of adopters and also increase diffusion rates for innovative services.

    Full Text Available Information concerning the occurrence and consequences of depression in the workplace is scarce. This study estimates how workers perceive depression, to investigate depression-related disabilities, and management of depression in the workplace. This investigation is based on a cross-sectional web-based survey of 1,000 workers recruited from online sources. The participants were Brazilian workers, aged 16–64 years, current workers and managers, or who have worked within the past year. Subjects answered a 13-item questionnaire about depression, its related consequences in the workplace, and available resources to handle depression. Common symptoms attributable to depression were crying, loss of interest, and sadness. Almost one in five participants reported having ever been labeled by a doctor/medical professional as suffering from depression. However, the majority of ever-depressed workers (73.5% remained working. Performance-related impairments were reported by around 60% of depressed workers who continued working. Over half of them also complained about cognitive symptoms (concentration difficulties, indecisiveness, forgetfulness. One in three workers had taken off work due to depression (mean 65.7 out-of-role days, with these periods being lengthier for men than women. Managers underestimated the number of days out-of-role (29.5 days. The findings suggested that identification and management of symptoms of depression should be set as a priority in worker’s health care.

    Facebook is the leading online media platform used by plastic surgeons. This study examined Facebook use among plastic surgeons and its perceived impact. A survey on Facebook use was distributed to two groups of plastic surgeons: 500 with professional Facebook pages and 500 without Facebook pages. Responses were stripped of identifying information and analyzed for statistical significance (p Facebook reported a negative impact on their practice, whereas 57 percent reported a very positive or positive impact. There was no correlation with perceived impact and number of "likes." Perceived advantages of Facebook included facilitation of patient feedback/communication (77 percent) and increased practice exposure (67 percent). Many surgeons (15 to 36 percent) did not follow the direct impact of Facebook on their practices. Some reported that Facebook was responsible for only one to 50 professional Web site hits and less than 5 percent of their new patient referrals in the past year. Estimated conversion-to-surgery rates were highly variable for Facebook users and nonusers. Most Facebook nonusers (67 percent) expected a "neutral" impact, expressing more concerns about unsolicited advertising (51 percent) and wasting time (47 percent). Plastic surgeons tend to perceive Facebook's impact on their practices as positive, but most do not track its direct effects on professional Web site hits, new referrals, or conversion-to-surgery rates. Plastic surgeons using Facebook are encouraged to monitor these parameters to determine whether its continued use is actually worthwhile.

  6. Assessment of the economic impact of environmental constraints on short-term hydropower plant operation

    International Nuclear Information System (INIS)

    Perez-Diaz, Juan I.; Wilhelmi, Jose R.

    2010-01-01

    Environmental constraints imposed on hydropower plant operation are usually given in the form of minimum environmental flows and, in some cases, in the form of maximum and minimum rates of change of flows, or ramping rates. Environmental constraints reduce the amount of water available to produce electricity and limit the contribution of peak hydropower plants to adapting the power supply to the demand and to providing certain ancillary services to the electrical grid, such as spinning reserve or load-frequency control. The objective of this paper is to assess the economic impact of environmental constraints on short-term hydropower plant operation. For that purpose, a revenue-driven daily optimization model based on mixed integer linear programming is used. The model considers the head variation and its influence on the units' efficiency, as well as the option of starting-up or shutting-down the plant at any hour of the day, should it be advantageous, while releasing the environmental flow through the bottom outlets. In order to illustrate the applicability of the methodology, it is applied in a real hydropower plant under different operating conditions and environmental constraints. (author)

    Provencher, Véronique; Jacob, Raphaëlle

    2016-03-01

    Healthy eating is an important determinant of health, but adherence to dietary guidelines remains a public health concern. Identifying factors that impact dietary habits is therefore important to facilitate healthy eating. One widely used strategy to help consumers make healthier food choices is nutrition information, such as labeling and claims. Despite the intention of these strategies to improve decision making, they can also be misunderstood or misinterpreted by consumers. The aim of this review is to explore food perceptions by examining how cognitive factors influence perceived healthiness of food, and the impact of perceived healthiness of food on food choices and intake. Overall findings of this review suggest that cognitive factors, such as type of food and branding, significantly contribute to judgmental bias and have an impact on perceived healthiness while not consistently or systematically influencing choice and intake.

  9. Impact Angle and Time Control Guidance Under Field-of-View Constraints and Maneuver Limits

    2018-04-01

    This paper proposes a guidance law which considers the constraints of seeker field-of-view (FOV) as well as the requirements on impact angle and time. The proposed guidance law is designed for a constant speed missile against a stationary target. The guidance law consists of two terms of acceleration commands. The first one is to achieve zero-miss distance and the desired impact angle, while the second is to meet the desired impact time. To consider the limits of FOV and lateral maneuver capability, a varying-gain approach is applied on the second term. Reduction of realizable impact times due to these limits is then analyzed by finding the longest course among the feasible ones. The performance of the proposed guidance law is demonstrated by numerical simulation for various engagement conditions.

    Chen, Weiping; Scott, Steffanie

    2014-12-01

    This study explores the concept of perceived embeddedness (PE) and its impact on purchasing behavior at an organic farmers' market. Based on a review of the prior literature, the study refines the conceptualization and measurement of PE as a second-order factor construct reflected in its three dimensions: perceived social embeddedness, perceived spatial embeddedness, and perceived natural embeddedness. The study also suggests that organic farmers' market shoppers' PE is positively related to the two measures of purchasing behavior: expenditure per visit and repurchase intention. In a sample of 492 organic farmers' market shoppers in Beijing municipality, China, the study find support for the second-order factor structure of PE and the theorized relationship between the shoppers' PE and their purchasing behavior. The study also discusses theoretical and managerial implications of the findings. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2008-12-01

    Full Text Available The purpose of this empirical study was to determine the impacts of distribution intensity on perceived quality and brand awareness, and to analyze the effects of perceived quality and brand awareness on brand loyalty. A structural equation model was used to identify the size and the direction of proposed relationships. The model was tested on a sample of 956 students using three brand categories in the manufacturing industry and three brand categories in the service industry. The proposed hypotheses were supported by the model. The results show that distribution intensity is positively related to perceived quality and brand awareness. Moreover, perceived quality and brand awareness were shown to be significant and positive predictors of brand loyalty. Managerial implications are discussed in the paper. The findings of this study could be of special interests to managers, professionals and those doing research in the field of distribution and brand management.

    2014-12-01

    Full Text Available To avoid risks, consumers tend to be failry thoughtful decision makers. Research has shown that consumers perceive risks associated with purchasing online and as a result online purchasing has not yet reached the numbers that were projected. In order for e-commerce to live up to its full potential, online retailers should gain an understanding of which perceived risks online purchasing consumers are most concerned with. This study aimed to assess the impact of perceived risk on online buying behaviour. Personal interview surveys were conducted in an emerging market whereby 200 respondents that have access to the internet were interviewed in selected malls with regards to their perceived risks when buying online. The results showed that perceived risk does have an impact on online buying behaviour, and that consumers that have not bought online in the past are likely not to do so in the future. The results show that characteristics of emerging markets are sufficiently distinct from developed markets in that consumers in developed markets seem to be more conservative when buying online. Marketers should therefore developed alternative marketing programs when communicating to these markets in an attempt to persuade consumers to buy online

    Full Text Available Orientation: Understanding the impact of resilience and perceived organisational support on employee engagement in a competitive sales environment. Research purpose: The aim of this study was to explore the relationship between resilience, perceived organisational support and employee engagement among pharmaceutical sales employees in a competitive sales environment; and to establish whether resilience and perceived organisational support hold predictive value for employee engagement. Motivation for the study: Limited research has focused on the unique context of employee engagement as a construct in professional sales. A broader understanding of resilience and perceived organisational support can provide sales organisations with a lever to create an environment where sales employees are more fully engaged. Research design, approach and method: A quantitative, exploratory, cross-sectional survey approach was used. A sample of 125 sales representatives from a South African pharmaceutical organisation participated in the research. The measuring instruments included the Utrecht Work Engagement Scale (UWES, Brief Resilience Scale (BRS and the Perceived Organisational Support Scale (POS. Main findings: Perceived organisational support, but not resilience impacted employee engagement in a competitive sales environment. Practical and managerial implications: Sales organisations’ interventions to improve sales employee engagement should focus on perceived organisational support. Contribution: The individual role of each construct provided insight into the sales context. The relationship between the constructs offered a different lens through which the drivers of employee engagement in sales can be viewed. This study contributes towards sales literature by including positive psychology and organisational support in a model of employee engagement.

  1. Olivine on Vesta as exogenous contaminants brought by impacts: Constraints from modeling Vesta's collisional history and from impact simulations

    Science.gov (United States)

    Turrini, D.; Svetsov, V.; Consolmagno, G.; Sirono, S.; Pirani, S.

    2016-12-01

    The survival of asteroid Vesta during the violent early history of the Solar System is a pivotal constraint on theories of planetary formation. Particularly important from this perspective is the amount of olivine excavated from the vestan mantle by impacts, as this constrains both the interior structure of Vesta and the number of major impacts the asteroid suffered during its life. The NASA Dawn mission revealed that olivine is present on Vesta's surface in limited quantities, concentrated in small patches at a handful of sites not associated with the two large impact basins Rheasilvia and Veneneia. The first detections were interpreted as the result of the excavation of endogenous olivine, even if the depth at which the detected olivine originated was a matter of debate. Later works raised instead the possibility that the olivine had an exogenous origin, based on the geologic and spectral features of the deposits. In this work, we quantitatively explore the proposed scenario of a exogenous origin for the detected vestan olivine to investigate whether its presence on Vesta can be explained as a natural outcome of the collisional history of the asteroid over the last one or more billion years. To perform this study we took advantage of the impact contamination model previously developed to study the origin and amount of dark and hydrated materials observed by Dawn on Vesta, a model we updated by performing dedicated hydrocode impact simulations. We show that the exogenous delivery of olivine by the same impacts that shaped the vestan surface can offer a viable explanation for the currently identified olivine-rich sites without violating the constraint posed by the lack of global olivine signatures on Vesta. Our results indicate that no mantle excavation is in principle required to explain the observations of the Dawn mission and support the idea that the vestan crust could be thicker than indicated by simple geochemical models based on the Howardite

    The present study measured the perceived impact and political and implementation feasibility of state-level policy strategies related to increasing access to healthy foods and limiting unhealthy foods. Potential state-level policy strategies to improve access to healthy foods were identified through a review of evidence-based literature and policy recommendations. Respondents rated the perceived impact and political and implementation feasibility of each policy on a five-point scale using online surveys. Washington State policy process. Forty-nine content experts (national researchers and subject experts), forty policy experts (state elected officials or their staff, gubernatorial or legislative policy analysts) and forty-five other stakeholders (state-level advocates, programme administrators, food producers). In aggregate, respondents rated policy impact and implementation feasibility higher than political feasibility. Policy experts rated policy strategies as less politically feasible compared with content experts (P political and implementation feasibility. These included policies related to nutrition standards in schools and child-care facilities, food distribution systems, urban planning projects, water availability, joint use agreements and breast-feeding supports. Although they may be perceived as potentially impactful, some policies will be more difficult to enact than others. Information about the potential feasibility of policies to improve access to healthy foods can be used to focus limited policy process resources on strategies with the highest potential for enactment, implementation and impact.

    As Earth accreted, volatiles were delivered by accreting material and lost by degassing and impact-driven ejection to space. The Moon-forming giant impact initiated the final catastrophic outgassing and bulk volatile ejection event on the early Earth. I-Pu-U-Xe systematics provide a powerful tool to probe degassing of the early Earth. Radiogenic 129Xe was produced by β-decay of the extinct nuclide 129I (t1/2 = 15.7 Ma) in the first ~90 Myr of Earth history. Fissiogenic 131Xe, 132Xe, 134Xe, 136Xe were produced in distinct, characteristic proportions by the fission of extinct short-lived 244Pu (t1/2 = 80.0 Myr) and extant long-lived 238U (t1/2 = 4.468 Gyr). Here we present radiogenic and fission Xe data in basalts from the Southwest Indian Ridge, and discuss them with other mantle-derived samples to shed light on early Earth volatile accretion and loss. Based on the ratio of radiogenic 129Xe to plutogenic 136Xe determined for the MORB source, we calculate an I-Pu-Xe closure age for the upper mantle of ~44-70 Myr after the start of the Solar System. The closure age should correspond to the end of catastrophic mantle outgassing during accretion, and thus constrains the age of the last giant impact (LGI). Our closure age is significantly older than previous Xe closure age determinations of ~100 Myr, and is also older than some direct radiometric ages of lunar crustal samples. In order to explore the effects of accretion timescales, partial early retention of Xe, and degassing associated with long-term mantle processing on Xe closure age, we develop a new model of I-Pu-U-Xe systematics. We find that for LGI's between ~35 and 70 Myr after the start of the Solar System, we are able to satisfy constraints on I-Pu-U-Xe systematics simultaneously without invoking partial retention of Xe prior to the last giant impact. For LGI's after ~80 Myr, partial retention of Xe prior to the LGI is required. Non-zero early retention of Xe is necessary to explain the budgets of primordial

    Full Text Available Two studies extended the communal goal congruity perspective to examine perceived incongruity between science careers and family caregiving goals. Study 1 examined beliefs about science careers among young adolescents, older adolescents, and young adults. Science careers were perceived as unlikely to afford family goals, and this belief emerged more strongly with age cohort. Study 1 also documented that the perception that science affords family goals predicts interest in pursuing science. Study 2 then employed an experimental methodology to investigate the impact of framing a science career as integrated with family life or not. For family-oriented women, the family-friendly framing of science produced greater personal favorability toward pursuing a science career. In addition, perceived fulfilment of the scientist described predicted personal favorability toward a science career path. We discuss the implications of these findings for research and for policy.

  5. Shopping the way to my goals: an analysis of purchase impact on perceived goal progress

    Directory of Open Access Journals (Sweden)

    Manuela Albornoz Gonçalves

    Full Text Available Abstract This article examines the impact of goal related purchases on goal progress perception, and whether this perception depends on the strength of association between product and goal. To test how consumers perceive the act of purchasing goal-related products, three experiments were conducted in an online setting. Participants exposed to purchasing situations perceived greater goal progress than participants exposed to usage situation or a control group. In addition, studies show that this effect is a result of strength of association between product and goal, since participants exposed to more instrumental products perceived greater goal progress than participants exposed to less instrumental products. Therefore, these studies demonstrate how consumers interpret goal related purchases, and the mechanism that influences this interpretation.

    Research demonstrates a negative impact of sleep disturbance on mood and affect; however, the biological mechanisms mediating these links are poorly understood. Amygdala reactivity to negative stimuli has emerged as one potential pathway. Here, we investigate the influence of self-reported sleep quality on associations between threat-related amygdala reactivity and measures of negative affect and perceived stress. Analyses on data from 299 participants (125 men, 50.5% white, mean [standard deviation] age = 19.6 [1.3] years) who completed the Duke Neurogenetics Study were conducted. Participants completed several self-report measures of negative affect and perceived stress. Threat-related (i.e., angry and fearful facial expressions) amygdala reactivity was assayed using blood oxygen level-dependent functional magnetic resonance imaging. Global sleep quality was assessed using the Pittsburgh Sleep Quality Index. Amygdala reactivity to fearful facial expressions predicted greater depressive symptoms and higher perceived stress in poor (β values = 0.18-1.86, p values .05). In sex-specific analyses, men reporting poorer global sleep quality showed a significant association between amygdala reactivity and levels of depression and perceived stress (β values = 0.29-0.44, p values sleep quality or in women, irrespective of sleep quality. This study provides novel evidence that self-reported sleep quality moderates the relationships between amygdala reactivity, negative affect, and perceived stress, particularly among men.

    Currently, only four states have legalized recreational marijuana use for adults over 21 years of age. Therefore, little is known about the influence that legalization will have on adolescent marijuana use. This study examines how marijuana legalization has impacted the frequency and consequences of adolescent use in a sample of participants in a school-based, substance use intervention. We hypothesized that adolescents enrolled in the intervention in years after marijuana legalization would present with more problematic use compared to those enrolled prior, and that changes in the perceived risk of marijuana would be a mechanism of problematic use. Participants were 262 students enrolled in a school-based substance use intervention in 2010 to 2015. The Customary Drinking and Drug Use Record, Alcohol and Drug Use Consequences Questionnaire, and a decisional balance matrix were used to assess marijuana frequency, negative consequences, and perceived risk of use. A mediation model was used to test the degree to which marijuana legalization may lead to increased frequency and consequences of use through perceived risk. Findings indicated a significantly positive correlation between marijuana-related consequences and perceived risk post legalization. Despite relatively equal use between both groups, adolescents in the legalization group experienced higher levels of perceived risk and increased negative consequences. Due to the rising legalization status of marijuana in the United States, it is imperative that psychoeducation is provided to adults and adolescents about the consequences of underage marijuana use.

    In recent time climate change and its impact on human health and awareness constitute a set of complex and serious consequences to be tackled by an individual country. Climate change is not merely an environmental issue, but also it is a threat that goes beyond national borders. The purpose of this study is to identify the awareness and the impact of climate change, perceived by the young citizens in Malaysia by focusing on gender differences. Based on a survey of 200 respondents from different public and private University's students in Malaysia, this research used descriptive statistics and T-test to look into the research objective. The results revealed media can play an important role in the awareness of climate change. Meanwhile the male respondents have shown considerable attention on the physical impact of climate change like heat related stress. On the other hand female respondents have shown considerable attention to the psychological impact by the climate change. From a pragmatic perspective, the findings from this research will assists the policy makers to understand more about the perceived awareness on the climate change issues of the young citizens which ultimately assist them to inaugurate new initiatives to confront the challenges of climate changes. This research is among the pioneer study on the issue of the perceived awareness in regards to climate change in Malaysia by focusing on gender differences.

  9. Errorful and errorless learning: The impact of cue-target constraint in learning from errors.

    The benefits of testing on learning are well described, and attention has recently turned to what happens when errors are elicited during learning: Is testing nonetheless beneficial, or can errors hinder learning? Whilst recent findings have indicated that tests boost learning even if errors are made on every trial, other reports, emphasizing the benefits of errorless learning, have indicated that errors lead to poorer later memory performance. The possibility that this discrepancy is a function of the materials that must be learned-in particular, the relationship between the cues and targets-was addressed here. Cued recall after either a study-only errorless condition or an errorful learning condition was contrasted across cue-target associations, for which the extent to which the target was constrained by the cue was either high or low. Experiment 1 showed that whereas errorful learning led to greater recall for low-constraint stimuli, it led to a significant decrease in recall for high-constraint stimuli. This interaction is thought to reflect the extent to which retrieval is constrained by the cue-target association, as well as by the presence of preexisting semantic associations. The advantage of errorful retrieval for low-constraint stimuli was replicated in Experiment 2, and the interaction with stimulus type was replicated in Experiment 3, even when guesses were randomly designated as being either correct or incorrect. This pattern provides support for inferences derived from reports in which participants made errors on all learning trials, whilst highlighting the impact of material characteristics on the benefits and disadvantages that accrue from errorful learning in episodic memory.

    Extant literature suggested that positive organizational climate leads to higher levels of organizational commitment, which is an important concept in terms of employee attitudes, likewise, the concept of perceived organizational performance, which can be assumed as a mirror of the actual performance. For healthcare settings, these are important matters to consider due to the fact that the service is delivered thoroughly by healthcare workers to the patients. Therefore, attitudes and perceptions of the employees can influence how they deliver the service. The aim of this study was to evaluate healthcare employees' perceptions of organizational climate and test the hypothesized impact of organizational climate on organizational commitment and perceived organizational performance. The study adopted a quantitative approach, by collecting data from the healthcare workers currently employed in public hospitals in North Cyprus, utilizing a self-administered questionnaire. Collected data was analyzed with the help of Statistical Package for Social Sciences, and ANOVA and Linear Regression analyses were used to test the hypothesis. Results revealed that organizational climate is highly correlated with organizational commitment and perceived organizational performance. Simple linear regression outcomes indicated that organizational climate is significant in predicting organizational commitment and perceived organizational performance. There was a positive and linear relationship between organizational climate with organizational commitment and perceived organizational performance. Results from the regression analysis suggested that organizational climate has an impact on predicting organizational commitment and perceived organizational performance of the employees in public hospitals of North Cyprus. Organizational climate was found to be statistically significant in determining the organizational commitment of the employees. The results of the study provided some critical

  11. The aesthetics of hazardous waste - Distinguishing visual impacts from publicly perceived risk

    Sheppard, S.

    1986-01-01

    The need to address the aesthetic impacts of hazardous waste projects on the environment and the public stems from two sources: government regulations which specifically require assessment of aesthetic effects; and rapidly increasing public concern for perceived impacts and risks of existing or proposed hazardous waste facilities. How aesthetic issues are handled on hazardous waste projects can potentially have significant implications on the fate of those projects. These implications range from delays in the permitting process to denial of sites or costly legal judgments in damage suits. This paper discusses strategies for evaluating the aesthetic/perceptual aspects of hazardous waste. In particular, it focuses upon ways to distinguish visual concerns from other influences on public perceptions such as perceived health and safety risks

    Approximately a quarter of medication errors in the hospital occur at the administration phase, which is solely under the purview of the bedside nurse. The purpose of this study was to assess bedside nurses' perceived skills and attitudes about updated safety concepts and examine their impact on medication administration errors and adherence to safe medication administration practices. Findings support the premise that medication administration errors result from an interplay among system-, unit-, and nurse-level factors.

    The Shared Socioeconomic Pathways (SSPs) represent the next generation of future global change scenarios and their inclusion in the Coupled Model Intercomparison Project Phase 6 (CMIP6) scenarios reinforces the importance of a complete understanding of the SSPs. This study uses the Global Change Assessment Model (GCAM) to investigate the effects of limited water supplies on future withdrawals at regional and water basin scales across all SSPs in combination with various climate mitigation scenarios. Water supply is calculated using a global hydrologic model and water data from five ISI-MIP models across the four RCP scenarios. When water constraints are incorporated, our results show that water withdrawals are reduced by as much as 40% across all SSP scenarios without climate policies. As climate policies are imposed and become more stringent, water withdrawals increase in regions already affected by water stress in order to allow for greater biomass production. The results of this research show the importance of including water resource constraints within the SSP scenarios for establishing water withdrawal scenarios under a wide range of scenarios including different climate policies. The results will also provide data products - such as gridded land use and water demand estimates - of potential interest to the impact, adaptation, and vulnerability community following the SSP scenarios.

    This report examines constraints due to the connection of distributed generators to the distribution network focusing on small generators with the aim of developing technical and economic models to examine the relationship between the initial investment and the ensuing cost of the constraints under different scenarios. Constraints are defined as limitations to operation of connected generators, and the types of constraints, and the allocation of reinforcement and constraint costs are considered. Details are given of the modeling of sections of urban, rural and semi-rural network at Faversham, and the current constraints on this network are described.

    2018-01-07

    The aim of this two-wave study has been to test the spillover and crossover of job and family demands on changes in perceived stress at work and in the family. Specifically, we proposed that demands from one domain (work or family) spilled over to another domain through interrrole conflict (work-family/family-work conflict) and context-specific self-efficacy. Additionally, we hypothesized that changes in perceived stress were impacted not only by a person's own demands through interrole conflict but also by the demands of one's significant other, in the process of crossover. The study was of dyadic design and it was conducted online, among 130 heterosexual couples, at 2 time points separated by 3 months interval. Hypotheses were verified by means of the path analysis. No support was found for the spillover of job and family demands on changes in perceived stress through interrole conflict and self-efficacy, neither for women nor for men. With regard to the crossover, no support was found for the actor effects, i.e., a person's demands did not impact changes in one's own work- and family-related perceived stress but partial support was found for the partner effects, i.e., women's job demands were associated with men's changes in work and family-related stress through women's work-family conflict, and men's family demands were associated with women's change in family-related perceived stress through men's family-work conflict. The study is a longitudinal test of the Spillover-Crossover model and Work-Home Resources model demonstrating that job and family demands are transmitted across domains and across partners in the intimate relationships through the interrole conflict but the nature of this crossover is different for men and women.

    Full Text Available The negative effects of traditional bullying and, recently, cyberbullying on victims are well documented, and abundant empirical evidence for it exists. Cybervictimization affects areas such as academic performance, social integration and self-esteem, and causes emotions ranging from anger and sadness to more complex problems such as depression. However, not all victims are equally affected, and the differences seem to be due to certain situational and personal characteristics. The objective of this study is to analyze the relationship between perceived emotional intelligence and the emotional impact of cybervictimization. We hypothesize that emotional intelligence, which has previously been found to play a role in traditional bullying and cyberbullying, may also affect the emotional impact of cyberbullying.The participants in our study were 636 university students from two universities in the south of Spain. Three self-report questionnaires were used: the European Cyberbullying Intervention Project Questionnaire, the Cyberbullying Emotional Impact Scale; and Trait Meta-Mood Scale-24. Structural Equation Models were used to test the relationships between the analyzed variables.The results support the idea that perceived emotional intelligence, by way of a moderator effect, affects the relationship between cybervictimization and emotional impact. Taken together, cybervictimization and perceived emotional intelligence explain much of the variance observed in the emotional impact in general and in the negative dimensions of that impact in particular. Attention and Repair were found to be inversely related to Annoyance and Dejection, and positively related to Invigoration. Clarity has the opposite pattern; a positive relationship with Annoyance and Dejection and an inverse relationship with Invigoration. Various hypothetical explanations of these patterns are discussed.

    Background Oral health is not merely the absence of oral disease and dysfunction, but also influences the subject's social life and dento-facial self confidence. Objective To assess and correlate self perceived psychosocial impact of dental aesthetics among young adults based on gender. Subjects A convenience sample of Young adults of degree college in the age group of 18-23 years of Hyderabad city, India. Method Self perceived psychosocial impact of dental aesthetics was assessed using the psychosocial impact of dental aesthetics questionnaire (PIDAQ). The dental aesthetic index (DAI) was used to evaluate dental aesthetics among participants which includes 10 parameters of dento-facial anomalies related to both clinical and aesthetic aspects of the anterior teeth. Results The majority of the study population were 18 years of age (96; 31.4%) with a mean age of 19.2 ± 1.1 years. When the mean total score and individual domain scores of PIDAQ was compared based on gender, females showed higher statistical mean (p ≤ 0.05) for all except the psychology impact domain (p = 0.12). Based on DAI grading and gender, among both males [70 (32.9%)] and females [31 (33.3%)] the majority of them had a DAI score of ≤25 (grade1; normal/minor dental malocclusion). A significant negative correlation was observed between DAI, with PIDAQ and its domains (p ≤ 0.05) except for the dental self confidence (p = 0.72). Conclusion This study had examined the relationship between self-perceived psychosocial impact and dental aesthetics. So, early preventive or interceptive procedures should be carried out to prevent further psychosocial impacts on human life.

    Full Text Available Much has been written about service quality impacts on customer satisfaction. However, little research on this perspective has been carried out in military settings. The aim of this study is to examine the relationship between service quality and customer satisfaction, and moderating effects of perceived value in military medical centre. A survey method was employed and data was collected from customers at medical centers under the administration of Malaysian army organization. Analysis was performed using SmartPLS path model analysis. The results show two important findings: first, the interaction between four service quality components (i.e., tangible, reliability, responsiveness and assurance and customers’ perceived value were significantly correlated with customer satisfaction. Second, the interaction between one service quality component (i.e., tangible were not significantly correlated with customer satisfaction. In overall, this result confirms that effect of tangible, reliability, responsiveness and assurance on customer satisfaction has been moderated by customers’ perceived value. Conversely, effect empathy on customer satisfaction has not been moderated by customers’ perceived value. Further, this study offers discussion, implications and conclusion.

  1. The Impact of Perceived Stress and Coping Adequacy on the Health of Nurses: A Pilot Investigation

    2016-01-01

    Full Text Available Stress and coping abilities influence the health and work performance of nurses. However, little is known about the combined influence of stress perception and perceived coping adequacy and its impact on the health of nurses. This study examined the relationship between stress, coping, and the combined influences of perceived stress and coping abilities on health and work performance. A valid and reliable questionnaire was completed by 120 nurses in a Midwestern hospital in the USA. In general, the nurses were not healthy: 92% had moderate-to-very high stress levels; 78% slept less than 8 hours of sleep per night; 69% did not exercise regularly; 63% consumed less than 5 servings of fruits and vegetables per day; and 22% were classified as binge drinkers. When confronted with workplace stress, 70% of nurses reported that they consumed more junk food and 63% reported that they consumed more food than usual as a way of coping. Nurses in the “high stress/poor coping” group had the poorest health outcomes and highest health risk behaviors compared to those in other groups. The combined variables of perceived stress and perceived coping adequacy influenced the health of nurses. Therefore, worksite health promotion programs for nurses should focus equally on stress reduction, stress management, and the development of healthy coping skills.

    The impact of hop variety and hop aroma on perceived beer bitterness intensity and character was investigated using analytical and sensory methods. Beers made from malt extract were hopped with 3 distinctive hop varieties (Hersbrucker, East Kent Goldings, Zeus) to achieve equi-bitter levels. A trained sensory panel determined the bitterness character profile of each singly-hopped beer using a novel lexicon. Results showed different bitterness character profiles for each beer, with hop aroma also found to change the hop variety-derived bitterness character profiles of the beer. Rank-rating evaluations further showed the significant effect of hop aroma on selected key bitterness character attributes, by increasing perceived harsh and lingering bitterness, astringency, and bitterness intensity via cross-modal flavour interactions. This study advances understanding of the complexity of beer bitterness perception by demonstrating that hop variety selection and hop aroma both impact significantly on the perceived intensity and character of this key sensory attribute.

    The impact of perceived wellness on a range of external load parameters, rating of perceived exertion (RPE) and external load:RPE ratios, was explored during skill-based training in Australian footballers. Fifteen training sessions involving 36 participants were analysed. Each morning before any physical training, players completed a customised perceived wellness questionnaire (sleep quality, fatigue, stress, mood and muscle soreness). Microtechnology devices provided external load (average speed, high-speed running distance, player load and player load slow). Players provided RPE using the modified Borg category-ratio 10 RPE scale. Mixed-effect linear models revealed significant effects of wellness Z-score on player load and player load slow. Effects are reported with 95% confidence limits. A wellness Z-score of -1 corresponded to a -4.9 ± 3.1 and -8.6 ± 3.9% reduction in player load and player load slow, respectively, compared to those without reduced wellness. Small significant effects were also seen in the average speed:RPE and player load slow:RPE models. A wellness Z-score of -1 corresponded to a 0.43 ± 0.38 m·min(-1) and -0.02 ± 0.01 au·min(-1) change in the average speed:RPE and player load slow:RPE ratios, respectively. Magnitude-based analysis revealed that the practical size of the effect of a pre-training perceived wellness Z-score of -1 would have on player load slow was likely negative. The results of this study suggests that monitoring pre-training perceived wellness may provide coaches with information about the intensity of output that can be expected from individual players during a training session.

    The relationships between selected condition characteristics and self-esteem were investigated in a randomly drawn, community-based sample of 286 young adults with chronic illnesses and disabilities. Whether appraisals of the impact of the condition mediated relationships between condition characteristics and self-esteem, as measured by the Rosenberg Self-Esteem Scale, was also measured. As a group, the youth in this sample reported positive self-esteem. When sociodemographic and condition-related variables were considered simultaneously, maternal education, unpredictability of symptoms, prognosis, sensory impairment, and the presence of a co-occurring learning disability were found to have direct effects on esteem. Perceived impact mediated the relationship between condition characteristics and self-esteem. The results are discussed in relation to the role of impact appraisal in determining the emotional well-being of young adults with chronic illnesses.

    Full Text Available This study was conducted to examine the probable effect of perceived empowerment on job performance and the sample of research consisted of 230 participants working in tourism sector as front-line employees. The outcomes of this study indicated that psychological empowerment was positively correlated with employee job performance and employees’ job performance were mostly effected from self-determination and impact dimensions of empowerment. Moreover, tests were conducted to analyze the significant differences in participants’ perception of empowerment and job performance according to their demographic characteristics. There was a significant difference between perceived empowerment and gender, age and work experience where as there was no significant difference between empowerment and education levels. On the other hand, the relationship between job performance and work experience was supported however no relationship was found between job performance and gender, age and education level of the participants. Trying to find out what might possibly lead front-line employees to increased job performance, it can be claimed that psychological empowerment still turns out to be a central issue and therefore this research makes useful contributions to the current knowledge by entirely investigating the direct effect of perceived empowerment on employee job performance in hospitality industry where especially front-line employees spend most of their time directly with customers.

    Perceived self-efficacy (SE) is an important factor underlying psychological well-being. Refugees suffer many experiences that can compromise SE. This study tested the impact of enhancing perceived SE on coping with trauma reminders and distress tolerance in tortured refugees. Torture survivors (N = 40) were administered a positive SE induction in which they retrieved mastery-related autobiographical memories, or a non-SE (NSE) induction, and then viewed trauma-related images. Participants rated their distress following presentation of each image. Participants then completed a frustration-inducing mirror-tracing task to index distress tolerance. Participants in the SE condition reported less distress and negative affect, and improved coping in relation to viewing the trauma-related images than those in the NSE condition. The SE induction also led to greater persistence with the mirror-tracing task than the NSE induction. These findings provide initial evidence that promoting SE in tortured refugees can assist with managing distress from trauma reminders, and promoting greater distress tolerance. Enhancing perceived SE in tortured refugees may increase their capacity to tolerate distress during therapy, and may be a useful means to improve treatment response. © 2017 Wiley Periodicals, Inc.

  9. Impacts of Base-Case and Post-Contingency Constraint Relaxations on Static and Dynamic Operational Security

    Science.gov (United States)

    Salloum, Ahmed

    Constraint relaxation by definition means that certain security, operational, or financial constraints are allowed to be violated in the energy market model for a predetermined penalty price. System operators utilize this mechanism in an effort to impose a price-cap on shadow prices throughout the market. In addition, constraint relaxations can serve as corrective approximations that help in reducing the occurrence of infeasible or extreme solutions in the day-ahead markets. This work aims to capture the impact constraint relaxations have on system operational security. Moreover, this analysis also provides a better understanding of the correlation between DC market models and AC real-time systems and analyzes how relaxations in market models propagate to real-time systems. This information can be used not only to assess the criticality of constraint relaxations, but also as a basis for determining penalty prices more accurately. Constraint relaxations practice was replicated in this work using a test case and a real-life large-scale system, while capturing both energy market aspects and AC real-time system performance. System performance investigation included static and dynamic security analysis for base-case and post-contingency operating conditions. PJM peak hour loads were dynamically modeled in order to capture delayed voltage recovery and sustained depressed voltage profiles as a result of reactive power deficiency caused by constraint relaxations. Moreover, impacts of constraint relaxations on operational system security were investigated when risk based penalty prices are used. Transmission lines in the PJM system were categorized according to their risk index and each category was as-signed a different penalty price accordingly in order to avoid real-time overloads on high risk lines. This work also extends the investigation of constraint relaxations to post-contingency relaxations, where emergency limits are allowed to be relaxed in energy market models

    Full Text Available Background: Pregnancy loss is a distressing problem and retention of dead fetus in utero has its own ill effects on physical, psychological, and social aspects, and hence, it is better to recommend medical induction, provided this can be safely undertaken. Aims: The aim of this study is to compare the efficacy, tolerability, induction-delivery interval, and perceived stress scores between induction methods in late intrauterine fetal death (IUFD with misoprostol alone and mifepristone with misoprostol combination in a rural population of Eastern India. Materials and Methods: This pilot study was conducted on 125 patients after taking institutional ethical clearance and informed consent of the patients in a time span of 1 year. Group 2 patients received 200 mg of mifepristone per orally and observed for 48 h, followed by 50 μg misoprostol administered in the posterior vaginal fornix, and repeated 6th hourly up to a maximum of four doses. Group 1 received 50 μg misoprostol per vaginally 6 hourly for four doses. Induction-delivery interval was calculated. Perceived stress level was calculated on admission and before discharge. Results: Significantly lower induction-delivery interval was observed in Group 2 as compared to Group 1 with P < 0.001. There was no significant difference of Cohen's perceived stress scores on admission, but the difference was significantly lower in Group 2 on discharge with the value of P = 0.03. Group 1 had significantly lower hospital stay in days as compared to Group 2 of patients with P < 0.001. Conclusions: Patients with IUFD administered misoprostol per vaginally only may require shorter hospital stay as compared to patients administered with oral mifepristone followed by misoprostol vaginally but the delivery induction time increases significantly and may increase perceived stress levels which may have short- and long-term negative psychological impact.

    An approximate, semi-analytical heat conduction model for predicting the time-dependent temperature distribution in the region of a high-level waste repository has been developed. The model provides the basis for a systematic, inexpensive examination of the impact of several independent thermal design constraints on key repository design parameters and for determining the optimal set of design parameters which satisfy these constraints. Illustrative calculations have been carried out for conceptual repository designs for spent pressurized water reactor (PWR) fuel and reprocessed PWR high-level waste in salt and granite media.

    Current research in psychology suggests that unconscious processes influence a significant proportion of choices and decisions. To study the impact of a non-attentively perceived odour on food choices, we used a priming paradigm. We had previously shown that non-attentively perceived fruity odours could impact food choice intentions (on a menu card), guiding participants toward items containing more fruit and/or vegetables. The present study was designed to extend these findings, in a real-life consumption setting. One hundred and fifteen participants took part in this study, and were assigned randomly to either a control or a scented condition. On arrival in the laboratory, they were seated in a waiting room. For the scented condition, they were unobtrusively exposed to a pear odour, while under the control condition the waiting room was non-odorised. Following this waiting period, all participants moved into a non-odorised test room where they were asked to choose, from dishes served buffet-style, the starter, main course and dessert that they would actually eat for lunch. The results showed that participants subjected to the scented condition chose to consume the 'fruity' dessert (compote) more frequently than those who had waited under the control condition, who chose more frequently the dessert without fruit (brownie). In line with the findings of our previous study, these results confirm the idea of priming effects 'specific to the food cue'. To conclude, a non-attentively perceived fruity odour was shown to influence actual food choices, guiding individuals towards more fruity desserts. The involvement of implicit processes in food choices should be taken into account in guidelines and strategies designed to promote healthy eating. Copyright © 2014 Elsevier Ltd.

    The purpose of this study was to explore the perceived impact of an interprofessional education (IPE) program for health sciences students on two culturally diverse, underserved communities. A community resilience/capacity framework, consisting of catalysts (primarily the creation of awareness) and capital components: human (workforce development), social (networking and empowerment) and economic (volunteer labor and money spent by the program), provided the conceptual underpinnings for the study. Focus groups with stakeholders in two communities, one rural and one metropolitan, were audio-recorded, transcribed and analyzed by categorizing data according to each capital component. In addition to the concepts contained in the capacity framework a new category, informational capital (data specific to the community) emerged during the analysis. We suggest that by acting as a catalyst a community based interprofessional program can affect components of community resilience/capacity, primarily human, social, and informational capital. Using the community resilience/capacity framework facilitated exploration of the perceived impact of an educational program on one rural and one urban underserved community beyond assessing student outcomes or number of clients served.

    Full Text Available The purpose of this study is to determine which AMT has the greatest perceived impact on producer’s value and to identify which AMTs has been most successfully employed. The study population consists of senior manufacturing executives in electrical and electronic firms located in the northern region of Malaysia. The study addresses the senior manufacturing executives’ perceptions on how well specific AMTs have achieved the expectation of the firms implementing them. They are selected as respondents because of their understanding of the technology and their effects, and because as top manufacturing decision makers, their opinions are likely to shape the future technology of the organization. This study found that the type of AMT that perceived the greatest impact on producer’s value is Flexible Manufacturing System, due to its high effects on two dimensions of producer’s value: quality and cost while Just-in-Time is found to be the most successfully employed AMT among respondents. The findings of this study are significant as they contribute to the AMT literature especially in the context of Electrical and Electronic firms.

  16. Impact of environmental constraints and aircraft technology on airline fleet composition

    Moolchandani, Kushal A.

    This thesis models an airline's decisions about fleet evolution in order to maintain economic and regulatory viability. The aim is to analyze the fleet evolution under different scenarios of environmental policy and technology availability in order to suggest an optimal fleet under each case. An understanding of the effect of aircraft technologies, fleet size and age distribution, and operational procedures on airline performance may improve the quality of policies to achieve environmental goals. Additionally, the effect of decisions about fleet evolution on air travel is assessed as the change in market demand and profits of an abstracted, benevolent monopolist airline. Attention to the environmental impact of aviation has grown, and this has prompted several organizations such as ICAO (and, in response, NASA) to establish emissions reduction targets to reduce aviation's global climate impact. The introduction of new technology, change in operational procedures, etc. are some of the proposed means to achieve these targets. Of these, this thesis studies the efficacy of implementation of environmental policies in form of emissions constraints as a means to achieve these goals and assesses their impact on an airline's fleet evolution and technology use (along with resulting effects on air travel demand). All studies in this thesis are conducted using the Fleet-level Environmental Evaluation Tool (FLEET), a NASA sponsored simulation tool developed at Purdue University. This tool models airline operational decisions via a resource allocation problem and uses a system dynamics type approach to mimic airline economics, their decisions regarding retirement and acquisition of aircraft and evolution of market demand in response to the economic conditions. The development of an aircraft acquisition model for FLEET is a significant contribution of the author. Further, the author conducted a study of various environmental policies using FLEET.

    To predict, for French women, the impact of a cost constraint on the food choices required to provide a nutritionally adequate diet. Isocaloric daily diets fulfilling both palatability and nutritional constraints were modeled in linear programming, using different cost constraint levels. For each modeled diet, total departure from an observed French population's average food group pattern ("mean observed diet") was minimized. To achieve the nutritional recommendations without a cost constraint, the modeled diet provided more energy from fish, fresh fruits and green vegetables and less energy from animal fats and cheese than the "mean observed diet." Introducing and strengthening a cost constraint decreased the energy provided by meat, fresh vegetables, fresh fruits, vegetable fat, and yogurts and increased the energy from processed meat, eggs, offal, and milk. For the lowest cost diet (ie, 3.18 euros/d), marked changes from the "mean observed diet" were required, including a marked reduction in the amount of energy from fresh fruits (-85%) and green vegetables (-70%), and an increase in the amount of energy from nuts, dried fruits, roots, legumes, and fruit juices. Nutrition education for low-income French women must emphasize these affordable food choices.

    Full Text Available The study investigated the impact of liquidity constraints on development of new financial products in commercial banks. The descriptive research design was adopted and a case study of ZB Bank employed. A census sampling technique was adopted and questionnaires and interviews were self-administered by the researchers. Research outcomes proved that liquidity constraints are a major impediment to firm`s innovativeness. Financial project innovations are either not started, delayed or abandoned, but mostly the distribution and delivery of developed services for financial products are highly affected. The results of this study have contributed to existing literature in revealing that financial regulation tends to be another constraint for commercial banks discouraging product innovations. Rapid technological changes seem to fuel the need for new software and hardware for new product development thus necessitating the employment of a skilled workforce for new product development. Furthermore, customer demands are changing on a daily basis due to rapid changes in information technology thus making customer maintenance difficult for commercial banks. Based on the data gathered, the researchers concluded that there is a negative impact on new financial product development due to liquidity constraints. In such constrained times, we recommend that commercial banks should emphasize more the best technique suitable for successful new product development or invest their available funds in the development thereof.

    1990-08-01

    A sensitivity analysis based on weighted least-squares regression is presented to evaluate alternative methods for fitting lumped-parameter models to respiratory impedance data. The goal is to maintain parameter accuracy simultaneously with practical experiment design. The analysis focuses on predicting parameter uncertainties using a linearized approximation for joint confidence regions. Applications are with four-element parallel and viscoelastic models for 0.125- to 4-Hz data and a six-element model with separate tissue and airway properties for input and transfer impedance data from 2-64 Hz. The criterion function form was evaluated by comparing parameter uncertainties when data are fit as magnitude and phase, dynamic resistance and compliance, or real and imaginary parts of input impedance. The proper choice of weighting can make all three criterion variables comparable. For the six-element model, parameter uncertainties were predicted when both input impedance and transfer impedance are acquired and fit simultaneously. A fit to both data sets from 4 to 64 Hz could reduce parameter estimate uncertainties considerably from those achievable by fitting either alone. For the four-element models, use of an independent, but noisy, measure of static compliance was assessed as a constraint on model parameters. This may allow acceptable parameter uncertainties for a minimum frequency of 0.275-0.375 Hz rather than 0.125 Hz. This reduces data acquisition requirements from a 16- to a 5.33- to 8-s breath holding period. These results are approximations, and the impact of using the linearized approximation for the confidence regions is discussed.

    When solving constraint satisfaction problems (CSPs), it is a common practice to rely on heuristics to decide which variable should be instantiated at each stage of the search. But, this ordering influences the search cost. Even so, and to the best of our knowledge, no earlier work has dealt with how first variable orderings affect the overall cost. In this paper, we explore the cost of finding high-quality orderings of variables within constraint satisfaction problems. We also study differen...

    The negative effects of traditional bullying and, recently, cyberbullying on victims are well-documented, and abundant empirical evidence for it exists. Cybervictimization affects areas such as academic performance, social integration and self-esteem, and causes emotions ranging from anger and sadness to more complex problems such as depression. However, not all victims are equally affected, and the differences seem to be due to certain situational and personal characteristics. The objective of this study is to analyze the relationship between perceived emotional intelligence (PEI) and the emotional impact of cybervictimization. We hypothesize that EI, which has previously been found to play a role in traditional bullying and cyberbullying, may also affect the emotional impact of cyberbullying. The participants in our study were 636 university students from two universities in the south of Spain. Three self-report questionnaires were used: the "European Cyberbullying Intervention Project Questionnaire," the "Cyberbullying Emotional Impact Scale"; and "Trait Meta-Mood Scale-24." Structural Equation Models were used to test the relationships between the analyzed variables. The results support the idea that PEI, by way of a moderator effect, affects the relationship between cybervictimization and emotional impact. Taken together, cybervictimization and PEI explain much of the variance observed in the emotional impact in general and in the negative dimensions of that impact in particular. Attention and Repair were found to be inversely related to Annoyance and Dejection, and positively related to Invigoration. Clarity has the opposite pattern; a positive relationship with Annoyance and Dejection and an inverse relationship with Invigoration. Various hypothetical explanations of these patterns are discussed.

    Full Text Available For the understanding of the impact of meteorological stressors on human perceptions of thermal comfort, it is essential to examine in detail the joint variability of atmospheric conditions and human perception. We designed an interdisciplinary experimental setup to generate data of both human-biometeorological and individual human perception at two different urban public places in the city of Aachen, Germany. Meteorological measurements at the human-biometeorological standard height of 1.1 m a.g.l. were taken during typical winter weather situations as well as extreme summer weather situations to analyze potentially seasonal effects. Pedestrians and tourists at the study site were selected as participants for face-to-face questionnaire-based interviews. We took measurements and held interviews between 10:00 h and 17:00 h (CEST/CET to record the daytime agreement/deviations at different inner urban measurement locations. Based on an overall physical approach of thermal load, UTCI (Universal Thermal Climate Index values are calculated. A maximum of +34.1 °C for summertime and a minimum of +2.6 °C for wintertime could be found. The meteorological parameters of air temperature (Ta$T_{a}$, mean radiant temperature (Tmrt$T_{\\text{mrt}}$ and vapor pressure (VP are compared with data perceived by the persons interviewed. In winter, Ta$T_{a }$ shows a significant relation to the overall weather perception (r=0.28$r = 0.28$; p<0.05$p<0.05$ while the overall comfort of the participants is significantly related to perceived solar heat (r=0.27$r = 0.27$; p<0.5$p<0.5$ as well as to perceived Ta$T_{a}$ (r=0.4$r = 0.4$; p<0.002$p<0.002$. Quite different resulting patterns occurred for the summer campaign. None of the physical variables significantly affected the weather perception. Only the perceived Ta$T_{a}$ revealed a significant relation to the overall weather perception (r=0.27$r=0.27$; p<0.002$p<0.002$.

    Women are still underrepresented at the highest management levels. The think-manager-think-male phenomenon suggests that leadership is associated with male rather than female attributes. Although styling has been shown to influence the evaluation of women's leadership abilities, the relevant specific features have been left remarkably unaddressed. In a 2 × 2 × 2 × 2 (skirt/pants, with/without jewelry, loose hair/braid, with/without makeup) between-subjects design, 354 participants evaluated a woman in a photograph. Women with makeup, pants, or with jewelry were rated as more competent than women without makeup, with skirts, or without jewelry. A combination of loose hair and no makeup was perceived as warmest, and women with loose hair were more likely to be hired than those with braids. In sum, even subtle changes in styling have a strong impact on how women's leadership abilities are evaluated.

    High fidelity simulation allows training of foundation doctors in a safe, structured environment. We explored the perceived impact of such training on subsequent clinical practice. 82 doctors attended and 52% responded to a follow up questionnaire sent two months after their training. 88% felt better able to manage the acutely ill patient than they did before their training. All cited simulation training as a reason for this and 44% felt simulation training was the main contributor. The remainder cited clinical experience as the main contributor. 53% gave real clinical examples where they applied skills attributed to simulation training. Doctors reflected positively on simulation training sometime after the experience, demonstrated transference of learnt skills and felt more confident at work.

    The aim of the current study was to determine the impact of acculturation, ethnic identity, and religious affiliation on perceived discrimination for persons of Arab and Middle Eastern descent. Two aspects of acculturation (ethnic society immersion and dominant society immersion), religious affiliation, and ethnic identity were measured using a final sample of 177 individuals of Arab or Middle Eastern descent. Results indicated that Arab/Middle Eastern Americans who reported lower levels of dominant society immersion tended to report higher levels of discrimination. Furthermore, Muslims reported a higher level of discrimination than Christians but this finding was moderated by level of acculturation. Specifically, Muslims who reported a high level of dominant society immersion experienced the most discrimination, whereas Christians who reported a high level of dominant society immersion reported less discrimination. Study implications are discussed. (c) 2009 APA, all rights reserved.

    Cash transfer programmes are increasingly recognised as promising and scalable interventions that can promote the health and development of children. However, concerns have been raised about the potential for cash transfers to contribute to social division, jealousy and conflict at a community level. Against this background, and in our interest to promote community participation in cash transfer programmes, we examine local perceptions of a community-led cash transfer programme in Eastern Zimbabwe. We collected and analysed data from 35 individual interviews and three focus group discussions, involving 24 key informants (community committee members and programme implementers), 24 cash transfer beneficiaries, of which four were youth, and 14 non-beneficiaries. Transcripts were subjected to thematic analysis and coding to generate concepts. Study participants described the programme as participatory, fair and transparent - reducing the likelihood of jealousy. The programme was perceived to have had a substantial impact on children's health and education, primarily through aiding parents and guardians to better cater for their children's needs. Moreover, participants alluded to the potential of the programme to facilitate more transformational change, for example by enabling families to invest money in assets and income generating activities and by promoting a community-wide sense of responsibility for the support of orphaned and vulnerable children. Community participation, combined with the perceived impact of the cash transfer programme, led community members to speak enthusiastically about the programme. We conclude that community-led cash transfer programmes have the potential to open up for possibilities of participation and community agency that enable social acceptability and limit social divisiveness.

    The current study compared the predicted social and career impact of socially withdrawn and reticent behaviors among participants from Western and East Asian countries. Three hundred sixty-one college students from 5 Western countries and 455 students from 3 East Asian countries read hypothetical vignettes describing socially withdrawn and shy behaviors versus socially outgoing and confident behaviors. Participants then answered questions following each vignette indicating the extent to which they would expect the subject of the vignette to be socially liked and to succeed in their career. Participants also completed measures of their own social anxiety and quality of life. The results indicated significant vignette-by-country interactions in that the difference in perceived social and career impact between shy and outgoing vignettes was smaller among participants from East Asian countries than from Western countries. In addition, significant negative correlations were shown between personal level of shyness and experienced quality of life for participants from both groups of countries, but the size of this relationship was greater for participants from Western than East Asian countries. The results point to the more negative impact of withdrawn and socially reticent behaviors for people from Western countries relative to those from East Asia. Copyright © 2011.

    A growing body of research has highlighted the importance of identifying resilience factors against suicidal behavior. However, no previous study has investigated potential resilience factors among individuals with Posttraumatic Stress Disorder (PTSD). The aim of this study was to examine whether perceived social support buffered the impact of PTSD symptoms on suicidal behavior. Fifty-six individuals who had previously been exposed to a traumatic event and reported PTSD symptoms in the past month (n = 34, 60.7% participants met the full criteria for a current PTSD diagnosis) completed a range of self-report measures assessing PTSD symptoms, perceived social support and suicidal behavior. Hierarchical regression analyses were conducted to examine whether perceived social support moderates the effects of PTSD symptoms on suicidal behavior. The results showed that perceived social support moderated the impact of the number and severity of PTSD symptoms on suicidal behavior. For those who perceived themselves as having high levels of social support, an increased number and severity of PTSD symptoms were less likely to lead to suicidal behavior. The current findings suggest that perceived social support might confer resilience to individuals with PTSD and counter the development of suicidal thoughts and behaviors. The milieu of social support potentially provides an area of further research and an important aspect to incorporate into clinical interventions for suicidal behavior in PTSD or trauma populations. © 2013.

    As the number of adults with autism spectrum disorder (ASD) grows, the need to identify modifiable correlates of positive outcomes and quality of life (QoL) gains in importance. Research indicates that perceived stress is significantly correlated with QoL in adults with ASD. Studies in the general population of individuals without disabilities indicate that greater participation in social and recreational activities may lessen the negative impact of perceived stress on well-being, and this association may also hold among adults with ASD. We hypothesized that: (1) perceived stress would be negatively associated with QoL; and (2) higher frequency of participation in social activities and recreational activities would moderate the relationship between perceived stress and QoL. We used data collected from 60 adults with ASD aged 24-55 and their mothers to address our hypotheses. Findings indicate that adults with ASD with higher perceived stress are likely to have poorer QoL. Furthermore, greater participation in recreational activities buffers the impact of perceived stress on QoL, but no buffering effect was observed for participation in social activities. These findings suggest that interventions and services that provide supports and opportunities for participation in recreational activities may help adults with ASD manage their stress and lead to better QoL.

    Full Text Available Background: Unpredictable spells of epileptic seizures would result in embarrassment in society and have some negative impact on the patients’ social activities. The aim of this study was to show the perceived impact of epilepsy by patients on different aspect of their social activities including occupation, marriage and education.Materials and Methods: We studied 179 epileptic patients age 16 years and over with face to face interview. Nine domains including relation to spouses, relation to family members, social life, general health, interpersonal communications and friendships, feelings about success, hope for future, ordinary life and cope with others were considered.Results: One hundred and seven men and 72 women were studied. Nearly 78% of the patients had generalized tonic-clonic seizures. More than half of the patients believed that epilepsy had affected their social life and activities. General health was negatively affected by this disease more than any other item; this may be due to uncontrolled spells or taking medications. About 15.5% of married and 39% of the single patients considered epilepsy as an obstacle to marry with their ideal spouses and more than half of the employed persons considered epilepsy as an obstacle for their job promotions.Conclusion: Epilepsy frequently impact on several aspects of life. The disease negatively affects social lives and activities, overall health, feelings about self, ability to work in paid employments, relationship with spouses, friends, and other family members, future plans, standards of living and ambitions of epileptic patients. Decreasing such impacts should be considered as an important part of treatment and proper management can certainly increase various aspects of life in these patients.

  1. False alarms and missed events: the impact and origins of perceived inaccuracy in tornado warning systems.

    Ripberger, Joseph T; Silva, Carol L; Jenkins-Smith, Hank C; Carlson, Deven E; James, Mark; Herron, Kerry G

    Theory and conventional wisdom suggest that errors undermine the credibility of tornado warning systems and thus decrease the probability that individuals will comply (i.e., engage in protective action) when future warnings are issued. Unfortunately, empirical research on the influence of warning system accuracy on public responses to tornado warnings is incomplete and inconclusive. This study adds to existing research by analyzing two sets of relationships. First, we assess the relationship between perceptions of accuracy, credibility, and warning response. Using data collected via a large regional survey, we find that trust in the National Weather Service (NWS; the agency responsible for issuing tornado warnings) increases the likelihood that an individual will opt for protective action when responding to a hypothetical warning. More importantly, we find that subjective perceptions of warning system accuracy are, as theory suggests, systematically related to trust in the NWS and (by extension) stated responses to future warnings. The second half of the study matches survey data against NWS warning and event archives to investigate a critical follow-up question--Why do some people perceive that their warning system is accurate, whereas others perceive that their system is error prone? We find that subjective perceptions are--in part-a function of objective experience, knowledge, and demographic characteristics. When considered in tandem, these findings support the proposition that errors influence perceptions about the accuracy of warning systems, which in turn impact the credibility that people assign to information provided by systems and, ultimately, public decisions about how to respond when warnings are issued. © 2014 Society for Risk Analysis.

  2. Impact of carbon intensity and energy security constraints on China's coal import

    2012-01-01

    Logistic and Gaussian Curves are adopted in this article to predict the coal production peak for Shanxi province, Henan province as well as the whole of China. According to the prediction based on the basic coal reserve data, coal production in China will reach its peak in the 2030 s while that of Shanxi and Henan provinces will be achieved by the 2040 s and 2020 s respectively. This article also assesses the influential factors of China's coal peak and revises the forecast of about China's coal demand by taking the CO2 intensity constraint into consideration, and then predicting the corresponding coal import. The results show that China would import 983 million tonnes of coal in 2020; which takes as high as 27% of China's total coal consumption. This article demonstrates that even if China fulfills CO2 intensity constraint, the country's energy situation would still be grim as a result of its high GDP growth rate. Therefore, China has to consider both CO2 intensity and energy security constraints when establishing strategic energy plan. Finally, this article suggests an adjustment of energy structure by which those constraints can be addressed and further assesses the effect of the adjusted energy structure. - Highlights: ► China's coal peak will arrive in 2040s when basic reserve data is used. ► China's peak production would be 4.8–5.8 billion tons. ► The energy security is still grim even if China meets CO 2 intensity constraint. ► The energy structure suggested should be “natural gas in place of oil and coal”.

    Parkinson's disease (PD) is characterized by a wide spectrum of non-motor symptoms that may impact negatively on the activities of the patient's daily life and reduce Health-related quality of life (HRQoL). The present study explored the impact of specific non-motor symptoms on the HRQoL in PD. Eighty-four outpatients underwent the Montreal Cognitive Assessment (MoCA) assessing global functioning and several questionnaires to assess depression, apathy, impulse control disorders (ICD), anxiety, anhedonia and functional impact of cognitive impairment. The perceived QoL was assessed by Parkinson's Disease Questionnaire (PDQ-8). The PD sample was divided into patients with high and low HRQoL around the median of PDQ-8 and compared on clinical features, cognitive and neuropsychiatric variables. A linear regression analysis, in which the global functioning, apathy, depression, anxiety, anhedonia, ICD and the functional autonomy scores were entered as independent variables and PDQ-8 score as dependent variable, was applied. Patients with lower HRQoL were more depressed, apathetic, anxious and showed more severe reduction of functional autonomy and global functioning than patients with high HRQoL. The regression analysis revealed that higher level of anxiety, executive apathy and more reduced functional autonomy were significantly associated with higher score on PDQ-8. The finding indicated that anxiety, apathy associated with impaired planning, attention and organization (i.e., executive apathy evaluated by the Dimensional Apathy Scale) and reduced functional autonomy contribute significantly to reduce the HRQoL in PD. Therefore, early identification and management of these neuropsychiatric symptoms should be relevant to preserve HRQoL in PD. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Environmental pollution is a significant global issue. Both objective (scientifically measured) environmental pollution and perceived levels of pollution are important predictors of self-reported health. The purpose of this study was to compare the associations between perceived environmental pollution and health in China, Japan, and South Korea. Data were obtained from the East Asian Social Survey and the Cross-National Survey Data Sets: Health and Society in East Asia, 2010 (n=7938; China, n=3866; Japan, n=2496; South Korea, n=1576). South Koreans perceived environmental pollution to be the most severe, while Japanese participants perceived environmental pollution to be the least severe. Although the Japanese did not perceive environmental pollution to be very severe, their self-rated physical health was significantly related to perceived environmental pollution, while the analogous relationships were not significant for the Chinese or Korean participants. Better mental health was related to lower levels of perceived air pollution in China, as well as lower levels of perceived all types of pollution in Japan and lower levels of perceived noise pollution in South Korea. Physical and mental health and individual socio-demographic characteristics were associated with levels of perceived environmental pollution, but with different patterns among these three countries.

    2018-05-01

    Previous research has indicated that perceived discrimination has harmful effects on migrant children's physical, mental and behavioral health. However, little is known as to whether these harmful effects cumulate to impact on migrant children's personalities. This study examines the effect of perceived discrimination on personality, as well as the moderating role of parental support in the discrimination-personality linkage. A purposeful convenience sample of 215 migrant children in Beijing, China, completed a standardized questionnaire. Migrant children experienced a moderate level of perceived discrimination, with Form 8 students experiencing greater discrimination than lower grades and those with lower family incomes also experiencing greater discrimination than those with higher family incomes. Perceived discrimination significantly predicted neuroticism; parental support significantly predicted extraversion, openness, agreeableness and conscientiousness, but the moderating effect of parental support was only marginally significant for the relation between discrimination and conscientiousness. This study underlines the need for researchers and policy makers to pay more attention to the impact of perceived discrimination on migrant children's personality development.

    There is a 40-year history of interest in the use of arm and hand gestures in treatments that target the reduction of aphasic linguistic impairment and compensatory methods of communication (Rose, 2006). Arguments for constraining aphasia treatment to the verbal modality have arisen from proponents of constraint-induced aphasia therapy (Pulvermüller et al., 2001). Confusion exists concerning the role of nonverbal treatments in treating people with aphasia. The central argument of this paper is that given the state of the empirical evidence and the strong theoretical accounts of modality interactions in human communication, gesture-based and multimodality aphasia treatments are at least as legitimate an option as constraint-based aphasia treatment. Theoretical accounts of modality interactions in human communication and the gesture production abilities of individuals with aphasia that are harnessed in treatments are reviewed. The negative effects on word retrieval of restricting gesture production are also reviewed, and an overview of the neurological architecture subserving language processing is provided as rationale for multimodality treatments. The evidence for constrained and unconstrained treatments is critically reviewed. Together, these data suggest that constraint treatments and multimodality treatments are equally efficacious, and there is limited support for constraining client responses to the spoken modality.

  14. Do Financial Constraints Moderate the Impact of Financing Decisions From Internal-financing Sources on Investment?

    Full Text Available To prevent investment growth in 2013 to 2015 from decreasing, the Industrial Ministry provided fiscal incentives to stimulate investment-growth. Nevertheless, the investment growth of manufacturing firms still declined. This condition indicated that fiscal stimulus might be ineffective to prevent investment-growth from declining. The decline of investment might be influenced by the increase of firm financial constraints to access a source of long term debts. This study aimed to examine the influence of financial constraints in moderating the effect of financing decisions from internal financing sources on investment. The population of the study was all listed-manufacturing firms in Indonesia from 2013 to 2015. Samples were chosen based on the availability of firms’ financial report covering the period of the study. The study concluded that financial constraints significantly weaken the effect of internal funding decision on investment. Unconstrained firms had a higher beta than constrained firms. Although unconstrained firms had an opportunity to choose their source of funding, they preferred to finance their investment from cash flows because the cost of debts might be much higher than the cost of equity.Hence, to help firms to finance their feasible investment opportunity, the government should not only provide tax incentives but also provide a low-interest loan.

    To collate and synthesize current knowledge of components of urban agriculture (UA) with a thematic emphasis on human health impact and a geographic emphasis on East Africa. Data management followed a structured approach in which key issues were first identified and then studies selected through literature search and personal communication. Evidence-based principles. Urban agriculture is an important source of food security for urban dwellers in East Africa. Descriptors of UA are location, areas, activities, scale, products, destinations, stakeholders and motivation. Many zoonotic and food-borne diseases have been associated with UA but evidence on human health impact and management is lacking. Major constraints to UA are illegality and lack of access to input and market; policy options have been developed for overcoming these. Urban agriculture is an important activity and likely to remain so. Both positive and negative human health impacts are potentially important but more research is needed to understand these and set appropriate policy and support levels.

    Full Text Available Abstract Background Dental caries, dental pain and reported oral problems influence people's oral quality of life and thus their perceived need for dental care. So far there is scant information as to the psychosocial impacts of dental diseases and the perceived treatment need in child populations of sub-Saharan Africa. Objectives Focusing on primary school students in Kilwa, Tanzania, a district deprived of dental services and with low fluoride concentration in drinking water, this study aimed to assess the prevalence of dental pain and oral impacts on daily performances (OIDP, and to describe the distribution of OIDP by socio-demographics, dental caries, dental pain and reported oral problems. The relationship of perceived need estimates with OIDP was also investigated. Methods A cross-sectional study was conducted in 2008. A total of 1745 students (mean age 13.8 yr, sd = 1.67 completed an extensive personal interview and under-went clinical examination. The impacts on daily performances were assessed using a Kiswahili version of the Child-OIDP instrument and caries experience was recorded using WHO (1997 criteria. Results A total of 36.2% (41.3% urban and 31.4% rural, p Conclusion Substantial proportions of students suffered from untreated dental caries, oral impacts on daily performances and perceived need for dental care. Dental pain and reported oral problems varied systematically with OIDP across the eight impacts considered. Eating and tooth cleaning problems discriminated between subjects who perceived need for dental treatment and those who did not.

    The aim of this study was to determine the influence of perceived authority on pediatric resuscitation teams' response to an incorrect order given by a medical superior. As part of a larger multicenter prospective interventional study, interprofessional pediatric resuscitation teams (n = 48) participated in a video-recorded simulated resuscitation scenario with an infant in unstable, refractory supraventricular tachycardia. A confederate actor playing a senior physician entered the scenario partway through and ordered the incorrect dose and delivery method of the antiarrhythmic, procainamide. Video recordings were analyzed with a modified Advocacy Inquiry Scale, assessing the teams' ability to challenge the incorrect order, and a novel confederate hierarchical demeanor rating. The association between Advocacy Inquiry score and hierarchical demeanor rating, and whether or not the confederate's incorrect order was followed were determined. Fifty percent (n = 24) of resuscitation teams followed the confederate's incorrect order. The teams' ability to challenge the incorrect order (P authority figure. Institution-based factors may impact this rate of incorrect medication administration.

    Current models of autobiographical memory suggest that self-identity guides autobiographical memory retrieval. Further, the capacity to recall the past and imagine one's self in the future (mental time travel) can influence social problem solving. We examined whether manipulating self-identity, through an induction task in which students were led to believe they possessed high or low self-efficacy, impacted episodic specificity and content of retrieved and imagined events, as well as social problem solving. Compared to individuals in the low self efficacy group, individuals in the high self efficacy group generated past and future events with greater (a) specificity, (b) positive words, and (c) self-efficacious statements, and also performed better on social problem solving indices. A lack of episodic detail for future events predicted poorer performance on social problem solving tasks. Strategies that increase perceived self-efficacy may help individuals to selectively construct a past and future that aids in negotiating social problems. Copyright © 2011 Elsevier Inc.

    Homophily, or "love for similar others," has been shown to play a fundamental role in the formation of interpersonal ties and social networks. Yet no study has investigated whether perceived similarities can affect tacit coordination. We had 68 participants attempt to maximize real monetary earnings by choosing between a safe but low paying option (that could be obtained with certainty) and a potentially higher paying but "risky" one, which depended on the choice of a matched counterpart. While making their choices participants were mutually informed of whether their counterparts similarly or dissimilarly identified with three person-descriptive words as themselves. We found that similarity increased the rate of "risky" choices only when the game required counterparts to match their choices (stag hunt games). Conversely, similarity led to decreased risk rates when they were to tacitly decouple their choices (entry games). Notably, though similarity increased coordination in the matching environment, it did not did not increase it in the decoupling game. In spite of this, similarity increased (expected) payoffs across both coordination environments. This could shed light on why homophily is so successful as a social attractor. Finally, this propensity for matching and aversion to decoupling choices was not observed when participants "liked" their counterparts but were dissimilar to them. We thus conclude that the impact of similarity of coordination should not be reduced to "liking" others (i.e., social preferences) but it is also about predicting them.

    The NEO-FFI has been widely used to demonstrate personality differences between people who stutter (PWS) and those who do not. These differences can be interpreted as indicators of internal sources of disability that contribute to handicaps associated with stuttering. The aim of the current study was to use this same tool to determine the perceived impact of stuttering on personality in order to provide a similar indicator of how external factors may contribute to the stuttering disability. A total of 49 non-stuttering young adults were given the NEO-FFI-3 after watching a video of someone stuttering (moderately to severely) and after watching a video of someone speaking fluently. Participants were asked to answer test items while imagining that they had spoken like the persons in the videos for their entire lives. When asked to assume the stuttering perspective, participants reported themselves to be significantly more neurotic (P stuttered perspectives are consistent with existing stereotypes about PWS. These differences are greater than and only partially consistent with differences in personality found between PWS and non-stuttering individuals. The findings support the notion that external factors (e.g. listener reactions and stereotypes about PWS) contribute strongly to the manner in which stuttering restricts function and results in handicaps.

    This study proposes a model explaining how social capital helps ease excessively required mental effort. Although organizational researchers have studied both social capital and cognitive load, no prior research has critically examined the role of social capital in improving individuals' mental load and effort and consequently enhancing job learning effectiveness. This study surveys participants made up of professionals in Taiwan's information technology industry. It measures the constructs with the use of 5-point Likert-type scale items modified from existing literature. The survey data were analyzed with the use of structural equation modeling. Job learning effectiveness is negatively influenced by role ambiguity and role conflict. Time pressure has a positive influence on role ambiguity and role conflict Although the relationship between task complexity and role ambiguity is insignificant, task complexity has a positive influence on role conflict. Because the relationship between network ties and role conflict is insignificant, trust has a negative influence on role conflict. Last, shared vision has a negative influence on role ambiguity. This study provides an example of how social capital can be applied as a useful remedy to ease the negative impact of perceived cognitive load on job learning effectiveness. The negative relationship between shared vision and role ambiguity suggests that a shared vision helps in disseminating organizationally common goals and directions among employees to alleviate individuals' mental efforts in dealing with the ambiguity of their job roles. A firm's management team should take actions to decrease role conflict by strengthening trust among employees.

    The study was conducted to determine whether perceived racial, economic and gender discrimination has an impact on contraception use and choice of method. We analyzed the first 2,500 women aged 14-45 years enrolled in the Contraceptive CHOICE Project, a prospective cohort study aimed to reduce barriers to obtaining long-acting reversible contraception. Items from the "Experiences of Discrimination" (EOD) scale measured experienced race-, gender- and economic-based discrimination. Overall, 57% of women reported a history of discrimination. Thirty-three percent reported gender- or race-based discrimination, and 24% reported discrimination attributed to socioeconomic status (SES). Prior to study enrollment, women reporting discrimination were more likely to report any contraception use (61% vs. 52%, pgender-, race- or SES-based discrimination were associated with increased current use of less effective methods [adjusted risk ratio (aRR) 1.22, 95% confidence interval (CI) 1.06-1.41; aRR 1.25, CI 1.08-1.45; aRR 1.23, CI 1.06-1.43, respectively]. After enrollment, 66% of women with a history of experience of discrimination chose a long-acting reversible contraceptive method (intrauterine device or implantable) and 35% chose a depo-medroxyprogesterone acetate or contraceptive pill, patch or ring. Discrimination negatively impacts a woman's use of contraception. However, after financial and structural barriers to contraceptive use were eliminated, women with EOD overwhelmingly selected effective methods of contraception. Future interventions to improve access and utilization of contraception should focus on eliminating barriers and targeting interventions that encompass race-, gender- and economic-based discrimination.

    Low compliance with training programs is likely to be one of the major reasons for inconsistency of the data regarding the effectiveness of current anterior cruciate ligament (ACL) injury prevention programs. Training methods that reduce training time and cost could favorably influence the effectiveness of ACL injury prevention programs. A newly designed knee extension constraint training device may serve this purpose. (1) Knee extension constraint training for 4 weeks would significantly increase the knee flexion angle at the time of peak impact posterior ground-reaction force and decrease peak impact ground-reaction forces during landing of a stop-jump task and a side-cutting task, and (2) the training effects would be retained 4 weeks after completion of the training program. Controlled laboratory study. Twenty-four recreational athletes were randomly assigned to group A or B. Participants in group A played sports without wearing a knee extension constraint device for 4 weeks and then played sports while wearing the device for 4 weeks, while participants in group B underwent a reversed protocol. Both groups were tested at the beginning of week 1 and at the ends of weeks 4 and 8 without wearing the device. Knee joint angles were obtained from 3-dimensional videographic data, while ground-reaction forces were measured simultaneously using force plates. Analyses of variance were performed to determine the training effects and the retention of training effects. Participants in group A significantly increased knee flexion angles and decreased ground-reaction forces at the end of week 8 (P ≤ .012). Participants in group B significantly increased knee flexion angles and decreased ground-reaction forces at the ends of weeks 4 and 8 (P ≤ .007). However, participants in group B decreased knee flexion angles and increased ground-reaction forces at the end of week 8 in comparison with the end of week 4 (P ≤ .009).

    Full Text Available Aim: The purpose of this study was to assess the self-perception of patients toward their dental appearance using the aesthetic component (AC of index of orthodontic treatment need (IOTN index and whether age and gender had any influence on it. Methods: A cross-sectional study was carried out to assess the perceived esthetic impact of malocclusion in 16-24 year-old subjects selected from the rural population of Faridabad, Haryana, India. The sample was divided into two groups, older adolescents and younger adults, and the AC of the IOTN index was applied. Results: The results showed that most subjects scored themselves as having an attractive dentition with no need for orthodontic treatment (60.91%. Gender-wise differences were not found to be statistically significant in relation to the perceived needs (P = 0.095, whereas age-wise differences were found to be statistically significant in relation to the perceived needs (P < 0.001. Conclusion: While the age seemed to have an impact on the perceived esthetic impact of malocclusion, the gender did not seemingly influence this self-perception.

  6. Control-Informed Geometric Optimization of Wave Energy Converters: The Impact of Device Motion and Force Constraints

    2015-12-01

    Full Text Available The energy cost for producing electricity via wave energy converters (WECs is still not competitive with other renewable energy sources, especially wind energy. It is well known that energy maximising control plays an important role to improve the performance of WECs, allowing the energy conversion to be performed as economically as possible. The control strategies are usually subsequently employed on a device that was designed and optimized in the absence of control for the prevailing sea conditions in a particular location. If an optimal unconstrained control strategy, such as pseudo-spectral optimal control (PSOC, is adopted, an overall optimized system can be obtained no matter whether the control design is incorporated at the geometry optimization stage or not. Nonetheless, strategies, such as latching control (LC, must be incorporated at the optimization design stage of the WEC geometry if an overall optimized system is to be realised. In this paper, the impact of device motion and force constraints in the design of control-informed optimized WEC geometries is addressed. The aim is to verify to what extent the constraints modify the connection between the control and the optimal device design. Intuitively, one might expect that if the constraints are very tight, the optimal device shape is the same regardless of incorporating or not the constrained control at the geometry optimization stage. However, this paper tests the hypothesis that the imposition of constraints will limit the control influence on the optimal device shape. PSOC, LC and passive control (PC are considered in this study. In addition, constrained versions of LC and PC are presented.

    Balancing groundwater depletion, socioeconomic development and food security in Saudi Arabia will require policy that promotes expansion of unconventional freshwater supply options, such as wastewater recycling and desalination. As these processes consume more electricity than conventional freshwater supply technologies, Saudi Arabia's electricity system is vulnerable to groundwater conservation policy. This paper examines strategies for adapting to long-term groundwater constraints in Saudi Arabia's freshwater and electricity supply sectors with an integrated modeling framework. The approach combines electricity and freshwater supply planning models across provinces to provide an improved representation of coupled infrastructure systems. The tool is applied to study the interaction between policy aimed at a complete phase-out of nonrenewable groundwater extraction and concurrent policy aimed at achieving deep reductions in electricity sector carbon emissions. We find that transitioning away from nonrenewable groundwater use by the year 2050 could increase electricity demand by more than 40% relative to 2010 conditions, and require investments similar to strategies aimed at transitioning away from fossil fuels in the electricity sector. Higher electricity demands under groundwater constraints reduce flexibility of supply side options in the electricity sector to limit carbon emissions, making it more expensive to fulfill climate sustainability objectives. The results of this analysis underscore the importance of integrated long-term planning approaches for Saudi Arabia's electricity and freshwater supply systems.

    Full Text Available When solving constraint satisfaction problems (CSPs, it is a common practice to rely on heuristics to decide which variable should be instantiated at each stage of the search. But, this ordering influences the search cost. Even so, and to the best of our knowledge, no earlier work has dealt with how first variable orderings affect the overall cost. In this paper, we explore the cost of finding high-quality orderings of variables within constraint satisfaction problems. We also study differences among the orderings produced by some commonly used heuristics and the way bad first decisions affect the search cost. One of the most important findings of this work confirms the paramount importance of first decisions.

    Objective Insufficient time for recovery between workdays may cause fatigue and disturbed sleep. This study evaluated the impact of an intervention that reduced weekly working hours by 25% on sleep, sleepiness and perceived stress for employees within the public sector. Method Participating workplaces (N=33) were randomized into intervention and control groups. Participants (N=580, 76% women) worked full-time at baseline. The intervention group (N=354) reduced worktime to 75% with preserved salary during 18 months. Data were collected at baseline and after 9 and 18 months follow-up. Sleep quality, sleep duration, sleepiness, perceived stress,and worries and stress at bedtime were measured with diary during one week per data collection. Result A multilevel mixed model showed that compared with the control group, at the 18-month follow-up, the intervention group had improved sleep quality and sleep duration (+23 minutes) and displayed reduced levels of sleepiness, perceived stress, and worries and stress at bedtime on workdays (Psleep length. Effect sizes were small (Cohen's f2sleep quality and worries and stress at bedtime as additional between-group factors did not influence the results. Conclusion A 25% reduction of weekly work hours with retained salary resulted in beneficial effects on sleep, sleepiness and perceived stress both on workdays and days off. These effects were maintained over an 18-month period. This randomized intervention thus indicates that reduced worktime may improve recovery and perceived stress.

    Regression mixture models are a novel approach to modeling the heterogeneous effects of predictors on an outcome. In the model-building process, often residual variances are disregarded and simplifying assumptions are made without thorough examination of the consequences. In this simulation study, we investigated the impact of an equality constraint on the residual variances across latent classes. We examined the consequences of constraining the residual variances on class enumeration (finding the true number of latent classes) and on the parameter estimates, under a number of different simulation conditions meant to reflect the types of heterogeneity likely to exist in applied analyses. The results showed that bias in class enumeration increased as the difference in residual variances between the classes increased. Also, an inappropriate equality constraint on the residual variances greatly impacted on the estimated class sizes and showed the potential to greatly affect the parameter estimates in each class. These results suggest that it is important to make assumptions about residual variances with care and to carefully report what assumptions are made.

    Pharmacists by their training have the competences and skills to promote safe use of medicines which is an essential component of patient safety. This study explored the perceptions of hospital pharmacists' role in medication safety in Ghana, identified their attendant challenges and ways of enhancing such roles in the future. A self-administered questionnaire was delivered to 200 pharmacists selected conveniently from the 10 regions of Ghana. Questions in the questionnaire were based on a systematic literature review that had catalogued and summarised all the activities of hospital pharmacists related to medication safety. A total of 176 (88% response rate) questionnaires were completed and returned. Almost all pharmacists (97.7%) believed that they were involved in medication safety activities in their daily routine. The frequently performed activities were counselling of out-patient (91.8%), training pharmacy and other clinical students (72.2%), reporting on medication errors (70%), and reconciling medications (69.2%). The mean weekly time spent on the activities ranged from 6.5 to 19.8 hours. Participants who had clinical pharmacy related additional qualifications (χ2 = 37.749; p = 0.049) and worked in tertiary care hospitals (χ2 = 26.6; p = 0.377) undertook more medication safety activities than those without. The cited challenges faced by participants included inadequate time available (62.7%), spending most time in managerial activities (47.3%), lack of formal structures of engagement (43.8%), lack of motivation by superiors (34.9%), and no formal schedule by supervisor (32%). Only 7.7% stated they lack interest in performing those activities. Pharmacists undertake many medication safety activities routinely that they perceive to have impact on patient care outcomes. Restructuring of their managerial roles will contribute to freeing time for pharmacists to engage more in those activities.

    Objectives To study the impact of performance obstacles on intensive care nurses‘ workload, quality and safety of care, and quality of working life (QWL). Performance obstacles are factors that hinder nurses‘ capacity to perform their job and that are closely associated with their immediate work system. Data Sources/Study Setting Data were collected from 265 nurses in 17 intensive care units (ICUs) between February and August 2004 via a structured questionnaire, yielding a response rate of 80 percent. Study Design A cross-sectional study design was used. Data were analyzed by correlation analyses and structural equation modeling. Principal Findings Performance obstacles were found to affect perceived quality and safety of care and QWL of ICU nurses. Workload mediated the impact of performance obstacles with the exception of equipment-related issues on perceived quality and safety of care as well as QWL. Conclusions Performance obstacles in ICUs are a major determinant of nursing workload, perceived quality and safety of care, and QWL. In general, performance obstacles increase nursing workload, which in turn negatively affect perceived quality and safety of care and QWL. Redesigning the ICU work system to reduce performance obstacles may improve nurses‘ work. PMID:19207589

    2010-01-01

    Lignocellulosic biomass is expected to become a key feedstock for renewable energy production. However, the potential supply strongly depends on farmers' willingness to grow the new perennial energy crops. Many economic assessments have been led at the farm level, all based on the standard net present value approach. This paper looks into the effect of farmers' liquidity constraints and risk preferences on switchgrass and miscanthus adoption by farmers. We study the problem of the land allocation between a traditional cropping system and an innovative one in a static framework, using four intertemporal choice models. We find that, in central France agronomic and economic conditions, switchgrass and miscanthus result to be less profitable in terms of annualised net margin than the usual rape/wheat/barley rotation. Nevertheless, they can be highly competitive as diversification crops when appropriate contracts are offered to farmers, despite the additional liquidity they require.

    Objectives: The purpose of the current study was to evaluate how weight classification influences safety by examining adults’ ability to meet a timing constraint: walking to the pace of an audio metronome. Methods: With a cross-sectional design, walking parameters were collected as 55 adults with normal (n=30) and overweight (n=25) body mass index scores walked to slow, normal, and fast audio metronome paces. Results: Between group comparisons showed that at the fast pace, those with overweight body mass index (BMI) had longer double limb support and stance times and slower cadences than the normal weight group (all psmetronome paces revealed that participants who were overweight had higher cadences at the slow and fast paces (all ps<0.05). Conclusions: Findings suggest that those with overweight BMI alter their gait to maintain biomechanical stability. Understanding how excess weight influences gait adaptation can inform interventions to improve safety for individuals with obesity. PMID:25730658

    Although potentially beneficial, task conflict may threaten teams because it often leads to relationship conflict. Prior research has identified a set of interpersonal factors (e.g., team communication, team trust) that help attenuate this association. The purpose of this article is to provide an alternative perspective that focuses on the moderating role of performance-related factors (i.e., perceived team performance). Using social identity theory, we build a model that predicts how task conflict associates with growth in relationship conflict and how perceived team performance influences this association. We test a three-wave longitudinal model by means of random coefficient growth modeling, using data from 60 ongoing teams working in a health care organization. Results provide partial support for our hypotheses. Only when perceived team performance is low, do task conflicts relate with growth in relationship conflict. We conclude that perceived team performance seems to enable teams to uncouple task from relationship conflict.

    The present research focused on bereaved parents' perceived grief similarity, and aimed to investigate the concurrent and longitudinal effects of the perceptions that the partner has less, equal, or more grief intensity than oneself on relationship satisfaction. Participants of our longitudinal study were 229 heterosexual bereaved Dutch couples who completed questionnaires 6, 13, and 20 months after the loss of their child. Average age of participants was 40.7 (SD = 9.5). Across 3 study waves, participants' perceived grief similarity and relationship satisfaction were assessed. To control for their effects, own grief level, child's gender, expectedness of loss, parent's age, parent's gender, and time were also included in the analyses. Consistent with the hypotheses, cross-sectional results revealed that bereaved parents who perceived dissimilar levels of grief (less or more grief) had lower relationship satisfaction than bereaved parents who perceived similar levels of grief. This effect remained significant controlling for the effects of possible confounding variables and actual similarity in grief between partners. We also found that perceived grief similarity at the first study wave was related to the highest level of relationship satisfaction at the second study wave. Moreover, results showed that perceived grief similarity was associated with a higher level in partner's relationship satisfaction. Results are discussed considering the comparison and similarity in grief across bereaved partners after child loss. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  4. The training value and constraints of established beliefs within teacher training: what is not seen but is perceived in the classroom

    2009-04-01

    Full Text Available The present article is a reflection on the value of beliefs in both initial and in-service teacher training, and the constraints that they may entail for learning and change. It is framed within the investigation on teachers’ thoughts and focuses on the construction of professional knowledge from the training-innovation relation taking an ecological perspective of knowledge. The concept of belief is defined as an affective and emotional personal dimension, intimately bound to one’s own culture that is manifested in the context in which we are immersed and of which we form part, which in turn exerts an influence on us and on what we do. It is argued that there is a need to take training in this dimension into account in order to promote autonomy as well as professional knowledge self-regulation. Significant constraints which can be overcome are pointed out: not to allow for variation, not to provide arguments, not to promote security to keep on advancing.

    This paper examines the impacts of CO 2 emission reduction target and carbon tax on future technologies selection and energy use in Bangladesh power sector during 2005-2035. The analyses are based on a long-term energy system model of Bangladesh using the MARKAL framework. The analysis shows that Bangladesh will not be able to meet the future energy demand without importing energy. However, alternative policies on CO 2 emission constraints reduce the burden of imported fuel, improve energy security and reduce environmental impacts. The results show that the introduction of the CO 2 emission reduction targets and carbon taxes directly affect the shift of technologies from high carbon content fossil-based to low carbon content fossil-based and clean renewable energy-based technologies compared to the base scenario. With the cumulative CO 2 emission reduction target of 10-20% and carbon tax of 2500 Taka/ton, the cumulative net energy imports during 2005-2035 would be reduced in the range of 39-65% and 37%, respectively, compared to the base scenario emission level. The total primary energy requirement would be reduced in the range of 4.5-22.3% in the CO 2 emission reduction targets and carbon tax 2500 Taka/ton scenarios and the primary energy supply system would be diversified compared to the base scenario. - Research highlights: → MARKAL model is used for the analysis in Bangladesh power sector. → The analysis shows that Bangladesh will not be able to meet the future electricity demand without importing fuel. → Alternative policies on CO 2 emission constraints reduce the burden of imported fuel, improve energy security and reduce environmental impacts.

    Recent models involving the Moon-forming giant impact hypothesis have managed to reproduce the striking isotopic similarity between the two bodies, albeit using two extreme models: one involves a high-energy small impactor that makes the Moon out of Earth's proto-mantle; the other supposes a gigantic collision between two half-Earths creating the Earth-Moon system from both bodies. Here we modeled the geochemical influence of the giant impact on Earth's mantle and found that impactors larger than 15% of Earth mass result in mantles always violating the present-day concentrations of four refractory moderately siderophile trace elements (Ni, Co, Cr, and V). In the aftermath of the impact, our models cannot further discriminate between a fully and a partially molten bulk silicate Earth. Then, the preservation of primordial geochemical reservoirs predating the Moon remains the sole argument against a fully molten mantle after the Moon-forming impact.

  9. Impact of a Diagnostic Pressure Equation Constraint on Tornadic Supercell Thunderstorm Forecasts Initialized Using 3DVAR Radar Data Assimilation

    2013-01-01

    Full Text Available A diagnostic pressure equation constraint has been incorporated into a storm-scale three-dimensional variational (3DVAR data assimilation system. This diagnostic pressure equation constraint (DPEC is aimed to improve dynamic consistency among different model variables so as to produce better data assimilation results and improve the subsequent forecasts. Ge et al. (2012 described the development of DPEC and testing of it with idealized experiments. DPEC was also applied to a real supercell case, but only radial velocity was assimilated. In this paper, DPEC is further applied to two real tornadic supercell thunderstorm cases, where both radial velocity and radar reflectivity data are assimilated. The impact of DPEC on radar data assimilation is examined mainly based on the storm forecasts. It is found that the experiments using DPEC generally predict higher low-level vertical vorticity than the experiments not using DPEC near the time of observed tornadoes. Therefore, it is concluded that the use of DPEC improves the forecast of mesocyclone rotation within supercell thunderstorms. The experiments using different weighting coefficients generate similar results. This suggests that DPEC is not very sensitive to the weighting coefficients.

  10. Project Plans, Constraints to Growth and the Impact of Cost Escalation through The Middle East and North Africa (MENA) Prism

    MENA national oil companies (NOCs) are targeting ambitious energy expansion, with mid-term plans for a 5.8 million b/d net boost to crude capacity, 1.9 million b/d more NGLs and 400 Bcm/year more gas, alongside significant refining and LNG additions. Nevertheless, a review of historical project delivery sounds a note of caution over timing - with a number of countries prone to delays and others, outright deferrals, even if market leaders, Saudi Arabia and Qatar, remain more resolutely on course. Cost escalation since 2002 has compounded the regional tendency towards delays, although the impact on project delivery has been moderated by a willingness to increase budgets where project economics remain sound. That leaves political factors as the principal constraint to regional expansion, complicated in part by increasing pluralism in political participation and valid concerns about the management of resources for long-term sustainability, rather than near-term profit. With most constraints to development expected to remain at the political level, there is a clear case for consumers to be more explicit about future needs. There is also a need to engage with growing constituencies in some states favouring a 'go slow' approach to hydrocarbon development where policymakers have made the case for considered expansion.

    2012-12-01

    Despite the efficacy of Brief Alcohol Screening and Intervention for College Students (BASICS), students with higher social anxiety appear vulnerable to poorer outcomes. A possible explanation for these outcomes is that corrective normative feedback (an active component of BASICS) may be less effective for socially anxious students if their beliefs about others' drinking are less malleable because of intense fear of negative evaluation for deviating from perceived drinking norms. This study evaluated whether socially anxious students demonstrated less change in perceived norms during BASICS. We also examined whether change in norm endorsement moderated the relation between social anxiety and BASICS outcomes. Undergraduates (n = 52) who underwent BASICS completed measures of drinking, social anxiety, and perceived norms at baseline and 4 weeks post-BASICS. Higher social anxiety was related to less change in norm endorsement after receiving BASICS. Change in perceived norms during treatment moderated the relation between social anxiety and follow-up drinking. Among students with smaller change in norm endorsement after BASICS, higher social anxiety was related to heavier follow-up drinking. Among students with greater changes to norm endorsement during BASICS, the effect of social anxiety was nonsignificant. Results suggest that corrective perceived norms interventions may be less effective among socially anxious students, contributing to continued heavy drinking. Development of social anxiety-specific BASICS components warrants attention. 2013 APA, all rights reserved

    1995-10-01

    Much of the discussion about the effects of an end-of-Cretaceous impact by a large extraterrestrial body in northwestern Yucatán has been done in the context of limited and partly erroneous published data on the Mesozoic stratigraphy of that area. Reexamination of cores and geophysical logs taken in several Pemex wells has produced improved lithologic and biostratigraphic correlation of the Jurassic to Maastrichtian section across the northern Yucatán peninsula. These data suggest that major disturbance of strata by an impact would have been confined to within about 100 km of the proposed impact center near Chicxulub. The only unusual lithologic unit is polymict breccia, which apparently was penetrated at or near the top of the Cretaceous section in all the deep wells of northern Yucatán. This breccia in Pemex wells Yucatán 1, 2, 4, 5A, and 6 is composed predominantly of detrital dolomite, limestone, and anhydrite clasts set in dolomitized carbonate mud matrix, which contains upper Maastrichtian foraminifers. These constituents, mixed with fragments of altered glass or melt rock, shocked quartz and feldspar, and basement rock, suggest an impact as the most likely origin for the breccia. The timing of brecciation is poorly constrained by biostratigraphic data. There is some evidence, however, that the breccia unit is overlain by about 18 m of uppermost Maastrichtian marls, suggesting an impact before the Cretaceous-Tertiary boundary. In addition, there may have been more than one episode of breccia deposition.

    The dynamic nature of healthcare ensures that early career nurses enter an uncertain and complex world of practice and consequently require support to develop their practice, build confidence and reach their potential. The New Zealand Nurse Entry to Practice programme for registered nurses in their first year of practice has been operating since 2005 to enable safe and confident practice, improve the quality of care, and positively impact on recruitment and retention. This academic and clinical programme was offered as a partnership between a university and a clinical provider with postgraduate academic credits gained. The aim of this study was to explore the perceived impact of postgraduate university education for early career nurses in one regional health area of New Zealand. Participants were registered nurses who had completed the early career nurse programme and their clinical preceptors. The research was conducted via an online survey of 248 nurses and three focus groups to explore how the programme was experienced and its impact on knowledge and practice. Early career nurses and their preceptors found that the programme enables improved knowledge and skills of patient assessment, application of critical thinking to clinical practice, perceived improvement in patient care delivery and outcomes, enhanced interprofessional communication and knowledge sharing, and had a positive impact on professional awareness and career planning. This clinical-academic partnership positively impacted on the clinical practice and transition experience of early career nurses and was closely aligned to an organization's strategic plan for nursing workforce development.

    Full Text Available The advances of information technology have significantly changed ways of teaching and learning in education. Compared to Computer Aided Instruction (CAI, Computer Aided Learning (CAL is student-centered and has become one of the popular ways in learning in different fields. As we all know, the Internet has been commonly used, and a variety of e-learning systems and materials have been designed and applied in schools. Researchers have applied theoretical models, such as TAM, TPB and UTAUT to explore individuals’ adoption and acceptance of technologies. In some researches, demographic individual difference has been proposed as an essential factor in adopting technologies. However, more studies have examined cognitiveoriented individual difference, especially Learning Style and Teaching Style, for users’ acceptance toward system usage. In this study, we explored how Perceived Teaching Style affects ESL/EFL (English as a Second/Foreign Language students’ adoption of the Moodle Reader System by using a revised TAM. Our results indicated that the ways how Perceived Ease to Use (PE relates to Perceived Usefulness (PU from the two Perceived Teaching Style clusters are different. This is valuable information for English course designers or instructors when they consider incorporating e-learning projects into their curriculum. It is also useful for system designers for developing their new learning management systems. For future studies, both Learning Style and Teaching Style will be examined to find out the relationship between the two factors and how they influence system users’ acceptance toward the learning management platform.

    Full Text Available Abstract Background The Perceived Impact of Problem Profile (PIPP was developed to provide a tool for measuring the impact of a health condition from the individual's perspective, using the ICF model as a framework. One of the aims of the ICF is to enable the comparison of data across countries, however, relatively little is known about the subjective experience of disability in middle and low-income countries. The aim of this study was to assess the validity of the Perceived Impact of Problem Profile (PIPP for use among adults with a disability in Thailand using Rasch analysis. Methods A total of 210 adults with mobility impairment from the urban, rural and remote areas of northeast Thailand completed the PIPP, which contains 23 items assessing both impact and distress across five key domains (Self-care, Mobility, Participation, Relationships, and Psychological Well-being. Rasch analysis, using RUMM2020, was conducted to assess the internal validity and psychometric properties of the PIPP Impact subscales. Validation of the PIPP Impact scales was conducted by comparing scores across the different response levels of the EQ5D items. Results Rasch analysis indicated that participants did not clearly differentiate between 'impact' and 'distress,' the two aspects assessed by the PIPP. Further analyses were therefore limited to the PIPP Impact subscales. These showed adequate psychometric properties, demonstrating fit to the Rasch model and good person separation reliability. Preliminary validity testing using the EQ5D items provided support for the PIPP Impact subscales. Conclusion The results provide further support for the psychometric properties of the PIPP Impact scales and indicate that it is a suitable tool for use among adults with a locomotor disability in Thailand. Further research is needed to validate the PIPP across different cultural contexts and health conditions and to assess the usefulness of separate Impact and Distress subscales.

    2006-01-01

    This paper outlines a theoretical approach to the problem of estimating and choosing dose-volume constraints. Following this approach, a method of choosing dose-volume constraints based on biological criteria is proposed. This method is called ''reverse normal tissue complication probability (NTCP) mapping into dose-volume space'' and may be used as a general guidance to the problem of dose-volume constraint estimation. Dose-volume histograms (DVHs) are randomly simulated, and those resulting in clinically acceptable levels of complication, such as NTCP of 5±0.5%, are selected and averaged producing a mean DVH that is proven to result in the same level of NTCP. The points from the averaged DVH are proposed to serve as physical dose-volume constraints. The population-based critical volume and Lyman NTCP models with parameter sets taken from literature sources were used for the NTCP estimation. The impact of the prescribed value of the maximum dose to the organ, D max , on the averaged DVH and the dose-volume constraint points is investigated. Constraint points for 16 organs are calculated. The impact of the number of constraints to be fulfilled based on the likelihood that a DVH satisfying them will result in an acceptable NTCP is also investigated. It is theoretically proven that the radiation treatment optimization based on physical objective functions can sufficiently well restrict the dose to the organs at risk, resulting in sufficiently low NTCP values through the employment of several appropriate dose-volume constraints. At the same time, the pure physical approach to optimization is self-restrictive due to the preassignment of acceptable NTCP levels thus excluding possible better solutions to the problem

  19. National Identification, Endorsement of Acculturation Ideologies and Prejudice: The Impact of the Perceived Threat of Immigration

    Directory of Open Access Journals (Sweden)

    Constantina Badea

    2018-05-01

    Full Text Available This paper examines how the perceived threat of immigration affects the links between national identification, endorsement of assimilation or multiculturalism, and prejudice against immigrants in France. One hundred thirty-five French undergraduates completed a questionnaire measuring these factors. Path analysis showed that higher national identification increased perception of immigrants as a threat, which in turn predicted increased endorsement of assimilation for immigrants. The link between endorsement of assimilation and prejudice was not significant. In contrast, lower national identification decreased perception of immigrants as a threat and, in turn, increased endorsement of multiculturalism and reduced levels of prejudice. An alternative model specifying perception of threat as an outcome of preferences for multiculturalism or assimilation did not fit the data well. Results suggest that perceived threat from immigration is the key factor that guides the preferences of the majority group for acculturation ideologies and, through these preferences, shapes intergroup attitudes.

    Full Text Available This study aimed to identify the relationships between green brand dimension (green brand awareness, green brand image, and green brand trust, green perceived value and customer’s intention to use green products. Data was collected through structured survey questionnaire from 384 customers of three hypermarkets in Kuala-Lumpur. Data was analyzed based on multiple regression analysis. The results indicate that there are significant relationships between green brand awareness, green brand trust, green perceived value, and customer’s intention to use green products. However, green brand image was not found to have significant relationship with customer’s intention to use green products. The discussion presented suggestions for marketers and researchers interested in green branding.

    2012-01-01

    Despite the efficacy of Brief Alcohol Screening and Intervention for College Students (BASICS), students with higher social anxiety appear vulnerable to poorer outcomes. A possible explanation for these outcomes is that corrective normative feedback (an active component of BASICS) may be less effective for socially anxious students if their beliefs about others’ drinking are less malleable due to intense fear of negative evaluation for deviating from perceived drinking norms. This study evalu...

    Much work has been done on the study of the biochemical mechanisms that result in ultrasensitive behavior of simple biochemical modules. However, in a living cell, such modules are embedded in a bigger network that constrains the range of inputs that the module will receive as well as the range of the module’s outputs that network will be able to detect. Here, we studied how the effective ultrasensitivity of a modular system is affected by these restrictions. We use a simple setup to explore to what extent the dynamic range spanned by upstream and downstream components of an ultrasensitive module impact on the effective sensitivity of the system. Interestingly, we found for some ultrasensitive motifs that dynamic range limitations imposed by downstream components can produce effective sensitivities much larger than that of the original module when considered in isolation.

  5. Experts: despite time constraints, motivational interviewing techniques can have lasting impact on drinkers, drug abusers.

    Science.gov (United States)

    2013-04-01

    Researchers have found that the Brief Negotiation Interview (BNI), a tool developed at Yale School of Medicine in New Haven, CT, can curb harmful drinking in patients when the tool is used with these patients in the emergency setting. Further, by using the same motivational interviewing techniques employed in the tool, experts say providers can help patients curb other harmful behaviors as well. The BNI consists of a series of questions that take about seven minutes to discuss with patients. The tool prompts patients to come up with their own reasons for changing harmful behaviors. To implement the BNI, emergency providers need training and constant reinforcement. Ideally, experts say the motivational interviewing techniques employed in the BNI need to become routine to have a lasting impact on patient care.

    An economic impact market analysis was conducted for 16 leading sectors of commercial Unmanned Aerial System (UAS) applications predicted to be enabled by 2020 through the NASA UAS Traffic Management (UTM) program. Subject matter experts from seven industries were interviewed to validate concept of operations (ConOps) and market adoption assumptions for each sector. The market analysis was used to estimate direct economic impacts for each sector including serviceable addressable market, capital investment, revenue recovery potential, and operations cost savings. The resultant economic picture distinguishes the agricultural, pipeline and railroad inspection, construction, and maritime sectors of the nascent commercial UAS industry as providing the highest potential economic value in the United States. Sensitivity studies characterized the variability of select UAS sectors economic value to key regulatory or UTM ConOps requirements such as weight, altitude, and flight over populated area constraints. Takeaways from the analysis inform the validation of UTM requirements, technologies and timetables from a commercial market need and value viewpoint. This work concluded in August 2015 and reflects the state of the UAS industry and market projections at that time.

    2017-09-01

    To examine whether perceptions of the impact of cancer are related to health-related quality of life (HRQoL) and psychological distress among survivors of cancer in adolescence and young adulthood (AYA). One hundred seventy-three AYA cancer survivors (aged 18-35 and 15-29 years at time of diagnosis) completed a mailed survey assessing impact of cancer (IOC-AYA), HRQoL (SF-36), and distress (BSI-18). Hierarchical linear regression models analyzed the independent effects of perceived impacts of cancer on HRQoL and distress after controlling for clinical and sociodemographic characteristics. Multivariate analyses also examined the extent to which positive and negative perceptions attenuated the effects of control variables on HRQoL and distress. Being unemployed or not in school, and self-reported health problems were significantly associated with worse physical HRQoL. Mental HRQoL and psychological distress appeared as a function of reporting both positive and negative impacts of cancer; mental health outcomes were better in AYAs reporting more positive and less negative impact of cancer in their lives. Perceived impact of cancer, in both positive and negative ways, attenuated the effects of sociodemographic and clinical factors on mental HRQoL and psychological distress. Results suggest that mental HRQoL and psychological distress, but not physical HRQoL, are a function of survivors' perceptions of how cancer has affected them and continues to affect them in both positive and negative ways. Findings suggest that opportunities for AYA cancer survivors to reframe or better understand the context of cancer in their lives may result in improved mental health outcomes.

    Full Text Available Background: Research has shown that orphans in sub-Saharan Africa are at increased risk for mental health problems. Exposure to maltreatment and HIV/AIDS-related stigmatization are related to orphans’ psychological distress. Yet, researchers stress the need for more research in low-income countries to identify which factors of being an orphan may lead to psychological distress. Objectives: The present study aims to systematically investigate orphans’ experiences of maltreatment and stigmatization to identify factors that relate to their psychological distress. Methods: In total, 89 Tanzanian children who had lost at least one parent were compared to 89 matched non-orphans (mean age: 11 years; 51% boys. We measured exposure to maltreatment and perceived stigmatization as an orphan. Mental health was assessed using the Strengths and Difficulties Questionnaire, the Children's Depression Inventory, the UCLA PTSD Index for Children, and the Reactive–Proactive Questionnaire. Results: Orphans reported significantly more experiences of neglect, but not of abuse. A group comparison revealed more depressive symptoms, posttraumatic stress symptoms, and aggressive behavior among orphans. Neglect, abuse, and stigmatization correlated with orphans’ internalizing and externalizing problems, yet only neglect and stigmatization were related to orphans’ depression severity. Perceived stigmatization moderated the relationship between neglect and depression. Conclusions: Our findings suggest that orphans in Tanzania are at increased risk of experiencing neglect. Maltreatment and perceived stigmatization may play a role in orphans’ psychological distress. Culturally appropriate and evidence-based interventions may help to prevent maltreatment and stigmatization of orphans.

    2011-03-01

    The alarming rates of medication nonadherence and its detrimental effect on long-term graft survival in pediatric kidney transplantation has called attention to identifying modifiable factors that promote better adherence and subsequent transplant outcomes. In a sample of 45 adolescent kidney transplant recipients (14.7 ± 3.3 years, 77.8% Caucasian, 39.5% female) and their primary caregivers, study aims included: 1) identifying sociodemographic and medical correlates of both caregiver- and patient-reported general family functioning (i.e., efficacy, flexibility, and communication) and 2) determining the unique contributions of these family functioning indices to perceived posttransplant adherence barriers. During a routine clinic visit, caregivers completed a sociodemographic form and questionnaire on general family functioning. Both caregivers and the adolescents completed a measure on perceived medication adherence barriers. Data identified household income and family structure as persistent correlates of family functioning. Familial efficacy and flexibility contributed significant variance to perceived adherence barriers. Family-based interventions enhancing modifiable family factors, such as flexibility and efficacy, in overcoming medication adherence barriers would likely promote more optimal health outcomes in the pediatric kidney transplant population.

    This study investigated the messages individuals receive from their partners about their bodies and their perceived impact on body image and sexual well-being. Young adult men (n=35) and women (n=57) completed open-ended questions identifying messages they had received from partners and the impact of these messages on their body image and sexual well-being. Content coding revealed three verbal (expressions of approval and pride, challenging negative beliefs, expressions of sexual attraction/arousal/desire) and two nonverbal (physical affection, physical expressions of sexual attraction/arousal/desire) positive messages as well as one verbal (disapproval/disgust) and two nonverbal (rejection, humiliation) negative messages. Some participants reported gender-related messages (muscularity/strength, genital appearance, breast appearance, weight, and comparison to others). Positive messages were seen to increase confidence, self-acceptance, and sexual empowerment/fulfillment, whereas negative messages decreased these feelings. Our findings suggest that even everyday, seemingly neutral messages are perceived to have an important impact on young adults. Copyright © 2016 Elsevier Ltd. All rights reserved.

  11. Threat appeals in health communication: messages that elicit fear and enhance perceived efficacy positively impact on young male drivers.

    2016-07-27

    Health communications often present graphic, threat-based representations of the potential consequences of health-risk behaviours. These 'threat appeals' feature prominently in public health campaigns, but their use is controversial, with studies investigating their efficacy reporting inconsistent, and often negative, findings. This research examined the impact of a threat-based road safety advertisement on the driving behaviour of young male drivers. To address limitations of previous research, we first identified a road safety advertisement that objectively and subjectively elicited fear using physiological and subjective measures. Study 1 (n = 62) examined the effect of this advertisement, combined with a manipulation designed to increase perceived efficacy, on speed choice. Study 2 (n = 81) investigated whether a state emotion, anger, impacts on the effectiveness of the advertisement in changing four distinct driving behaviours. Both studies examined short-term effects only. Study 1 findings indicated that a high threat message, when combined with high perceived efficacy, can lead to a decrease in speed choice. Study 2 results suggested that increased levels of state anger may counteract the potential value of combining fear-arousing threats and efficacy-building messages. Findings suggest that threat-based road safety communications that target affective (fear) and cognitive (perceived efficacy) mechanisms can positively affect driving behaviours. State emotions, such as anger, may negatively impact on the effectiveness of the message. Taken together, these findings provide additional support for the use of efficacy-building messages in threat-based communications, but highlight the need for further research into the complex array of affective influences on driving.

    Low alcohol labels are a set of labels that carry descriptors such as 'low' or 'lighter' to denote alcohol content in beverages. There is growing interest from policymakers and producers in lower strength alcohol products. However, there is a lack of evidence on how the general population perceives verbal descriptors of strength. The present research examines consumers' perceptions of strength (% ABV) and appeal of alcohol products using low or high alcohol verbal descriptors. A within-subjects experimental study in which participants rated the strength and appeal of 18 terms denoting low (nine terms), high (eight terms) and regular (one term) strengths for either (1) wine or (2) beer according to drinking preference. Thousand six hundred adults (796 wine and 804 beer drinkers) sampled from a nationally representative UK panel. Low, Lower, Light, Lighter, and Reduced formed a cluster and were rated as denoting lower strength products than Regular, but higher strength than the cluster with intensifiers consisting of Extra Low, Super Low, Extra Light, and Super Light. Similar clustering in perceived strength was observed amongst the high verbal descriptors. Regular was the most appealing strength descriptor, with the low and high verbal descriptors using intensifiers rated least appealing. The perceived strength and appeal of alcohol products diminished the more the verbal descriptors implied a deviation from Regular. The implications of these findings are discussed in terms of policy implications for lower strength alcohol labelling and associated public health outcomes. Statement of contribution What is already known about this subject? Current UK and EU legislation limits the number of low strength verbal descriptors and the associated alcohol by volume (ABV) to 1.2% ABV and lower. There is growing interest from policymakers and producers to extend the range of lower strength alcohol products above the current cap of 1.2% ABV set out in national legislation. There

  14. Impact of an e-learning program regarding patients' harmful alcohol consumption on the knowledge, attitudes and perceived competencies

    Evers, Eva; Hahn, Sabine; Metzenthin, Petra

    2018-01-24

    Background: Harmful alcohol consumption is associated with approximately 1600 deaths in Switzerland annually, and is the third-largest risk factor for various diseases worldwide. It has been shown that through early identification of problematic drinking behaviours along with preventive intervention, alcohol-related illnesses and mortality can be reduced. Therefore, nurses play a crucial role for patients with alcohol problems. However, the most common reasons for nurses not providing preventive intervention are a lack of knowledge, personal attitudes and uncertainty. Learning programs hold the potential for influencing these factors. Aim: The aim of this study was to assess the impact of an e-learning program regarding patients’ harmful alcohol consumption on the knowledge, attitudes and perceived competencies of nurses in an acute care hospital. Method: A pretest-posttest-study was conducted with 33 registered nurses prior to and upon completion of the e-learning program. Data was collected from December 2013 to March 2014 using a literature-based questionnaire. Results: It was shown that knowledge and perceived competencies significantly improved from pre-test to post-test. No significant differences were measured with regard to the attitudes. Conclusions: The results suggest that the alcohol e-learning program could be used to enhance nurses’ knowledge and perceived competencies, both of which are related to the reduction of uncertainty and improvement of confidence. To foster non-judgemental attitudes towards affected people, classroom courses are recommended in addition to the e-learning program and the implementation of directives.

    While the ocean’s large-scale overturning circulation is thought to have been significantly different under the climatic conditions of the Last Glacial Maximum (LGM), the exact nature of the glacial circulation and its implications for global carbon cycling continue to be debated. Here we use a global array of ocean–atmosphere radiocarbon disequilibrium estimates to demonstrate a ∼689±53 14C-yr increase in the average residence time of carbon in the deep ocean at the LGM. A predominantly southern-sourced abyssal overturning limb that was more isolated from its shallower northern counterparts is interpreted to have extended from the Southern Ocean, producing a widespread radiocarbon age maximum at mid-depths and depriving the deep ocean of a fast escape route for accumulating respired carbon. While the exact magnitude of the resulting carbon cycle impacts remains to be confirmed, the radiocarbon data suggest an increase in the efficiency of the biological carbon pump that could have accounted for as much as half of the glacial–interglacial CO2 change.

  16. National Coal Utilization Assessment. An integrated assessment of increased coal use in the Midwest: impacts and constraints. [14 states Midwest region

    Energy Technology Data Exchange (ETDEWEB)

    1977-10-01

    This study examines the impacts and constraints to increased coal production and use for a 14-state Midwestern region. The assessment considers technology characteristics, energy supply and demand trends, siting constraints, impacts on water availability and coal reserves, impacts on air and water quality, and ecosystems, effects of trace elements, social and economic impacts, and health risks. The significant air quality constraints to coal use are related to the short-term National Ambient Air Quality Standards, PSD standards, and exposure to sulfates. In general, cumulative water supply in the 14-state region is adequate to satisfy foreseeable energy requirements; however, on a localized basis significant water shortages may develop which could constrain a smaller portion of the energy development. Water quality impacts are primarily restricted to areas with insufficient water resources. Coal mining will continue to have significant effects on water quality in smaller streams draining the major coal regions unless strict control practices are maintained. Coal-conversion plants may cause localized water quality problems; however, the effluent characteristics of these plants are not well-known. A significant amount of the coal development is anticipated to occur in counties with high susceptibility to social and economic impacts. The timing, magnitude, and nature of these impacts could be mitigated by the development of effective management strategies.

  17. Impact of Information Technology, Clinical Resource Constraints, and Patient-Centered Practice Characteristics on Quality of Care

    2015-02-01

    Full Text Available Objective: Factors in the practice environment, such as health information technology (IT infrastructure, availability of other clinical resources, and financial incentives, may influence whether practices are able to successfully implement the patient-centered medical home (PCMH model and realize its benefits. This study investigates the impacts of those PCMH-related elements on primary care physicians’ perception of quality of care. Methods: A multiple logistic regression model was estimated using the 2004 to 2005 CTS Physician Survey, a national sample of salaried primary care physicians (n = 1733. Results: The patient-centered practice environment and availability of clinical resources increased physicians’ perceived quality of care. Although IT use for clinical information access did enhance physicians’ ability to provide high quality of care, a similar positive impact of IT use was not found for e-prescribing or the exchange of clinical patient information. Lack of resources was negatively associated with physician perception of quality of care. Conclusion: Since health IT is an important foundation of PCMH, patient-centered practices are more likely to have health IT in place to support care delivery. However, despite its potential to enhance delivery of primary care, simply making health IT available does not necessarily translate into physicians’ perceptions that it enhances the quality of care they provide. It is critical for health-care managers and policy makers to ensure that primary care physicians fully recognize and embrace the use of new technology to improve both the quality of care provided and the patient outcomes.

    Uncertainty in the simulation of the carbon cycle contributes significantly to uncertainty in the projections of future climate change. We use observations of forest fraction to constrain carbon cycle and land surface input parameters of the global climate model FAMOUS, in the presence of an uncertain structural error. Using an ensemble of climate model runs to build a computationally cheap statistical proxy (emulator) of the climate model, we use history matching to rule out input parameter settings where the corresponding climate model output is judged sufficiently different from observations, even allowing for uncertainty. Regions of parameter space where FAMOUS best simulates the Amazon forest fraction are incompatible with the regions where FAMOUS best simulates other forests, indicating a structural error in the model. We use the emulator to simulate the forest fraction at the best set of parameters implied by matching the model to the Amazon, Central African, South East Asian, and North American forests in turn. We can find parameters that lead to a realistic forest fraction in the Amazon, but that using the Amazon alone to tune the simulator would result in a significant overestimate of forest fraction in the other forests. Conversely, using the other forests to tune the simulator leads to a larger underestimate of the Amazon forest fraction. We use sensitivity analysis to find the parameters which have the most impact on simulator output and perform a history-matching exercise using credible estimates for simulator discrepancy and observational uncertainty terms. We are unable to constrain the parameters individually, but we rule out just under half of joint parameter space as being incompatible with forest observations. We discuss the possible sources of the discrepancy in the simulated Amazon, including missing processes in the land surface component and a bias in the climatology of the Amazon.

    To identify residents' perceived barriers to learning phacoemulsification surgical procedures and to evaluate whether virtual reality simulation training changed these perceptions. The ophthalmology residents undertook a simulation phacoemulsification course and proficiency assessment on the Eyesi system using the previously validated training modules of intracapsular navigation, anti-tremor, capsulorrhexis, and cracking/chopping. A cross-sectional, multicenter survey on the perceived difficulties in performing phacoemulsification tasks on patients, based on the validated International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric (ICO-OSCAR), using a 5-point Likert scale (1 = least and 5 = most difficulty), was conducted among residents with or without prior simulation training. Mann-Whitney U tests were carried out to compare the mean scores, and multivariate regression analyses were performed to evaluate the association of lower scores with the following potential predictors: 1) higher level trainee, 2) can complete phacoemulsification most of the time (>90%) without supervisor's intervention, and 3) prior simulation training. The study was conducted in ophthalmology residency training programs in five regional hospitals in Hong Kong. Of the 22 residents, 19 responded (86.3%), of which 13 (68.4%) had completed simulation training. Nucleus cracking/chopping was ranked highest in difficulty by all respondents followed by capsulorrhexis completion and nucleus rotation/manipulation. Respondents with prior simulation training had significantly lower difficulty scores on these three tasks (nucleus cracking/chopping 3.85 vs 4.75, P = 0.03; capsulorrhexis completion 3.31 vs 4.40, P = 0.02; and nucleus rotation/manipulation 3.00 vs 4.75, P = 0.01). In multivariate analyses, simulation training was significantly associated with lower difficulty scores on these three tasks. Residents who had completed Eyesi simulation training had higher

    This paper considers an asset allocation strategy over a finite period under investment uncertainty and short-sale constraints as a continuous time stochastic control problem. Investment uncertainty is characterised by a stochastic interest rate and inflation risk. If there are no short-sale constraints, the optimal asset allocation strategy can be solved analytically. We consider several kinds of short-sale constraints and employ the backward Markov chain approximation method to explore the ...

    The aims of this study were to evaluate (i) the effect of ethnicity, social deprivation, and normative orthodontic treatment need on orthodontic aesthetic self-perception, self-perceived need for orthodontic treatment, and oral aesthetic impact of malocclusion; (ii) the effect of ethnicity, social deprivation, and gender on perceived orthodontic treatment need and use of orthodontic services; (iii) the influence of perceived oral aesthetic impact of malocclusion on perceived need and wish for orthodontic treatment; and (iv) whether orthodontic treatment experience influences perceived oral aesthetic impact of malocclusion. A stratified, random sample of 434 14-15-year-old children from schools in Manchester, UK, was obtained. Information was collected on orthodontic aesthetic self-perception and orthodontic treatment experience using a questionnaire. The former data were combined to form an Oral Aesthetic Subjective Impact Scale (OASIS). Normative orthodontic treatment need was measured with the Index of Orthodontic Treatment Need (IOTN). Children with higher clinical need for orthodontic treatment perceived themselves as worse off than their peers with lower need. More socially deprived children or those with high IOTN aesthetic component (AC) scores had a higher (i.e. more negative) aesthetic impact (OASIS) score. Asians and females had higher IOTN dental health component (DHC) scores, but a better aesthetic appearance than Caucasians and males. More deprived children were less likely to have received orthodontic treatment. Despite this, OASIS scores were similar between treated and untreated children. Untreated children who wished for orthodontic treatment had higher IOTN AC and OASIS scores.

    To explore the mediation and moderation effects of personality traits on the relationship between self-perceived malocclusion and the psychosocial impact of dental esthetics. The sample included 252 subjects (62% female) aged 12-39 years. Self-perceived malocclusion was estimated using the 10-point scale Aesthetic Component of the Index of Orthodontic Treatment Need. The Psychosocial Impact of Dental Aesthetics Questionnaire was used to assess the psychological impact and the Big Five Inventory for personality traits. Moderation and mediation effects were evaluated with Pearson correlations and stepwise regression analysis, respectively. Self-perceived malocclusion ranged from 1 to 8 and was the most significant predictor of psychosocial impact of dental esthetics, whose unique contribution accounted for 11%-36.4% of variability, while age and sex accounted for 1.2%-2.5%.

The moderating effect of agreeableness was present in the relationship between self-perceived degree of malocclusion and Social Impact (SI), Psychological Impact (PI), and Aesthetic Concern (AC) (ΔR2  =  0.035, 0.020, and 0.013, respectively; P personality traits. Adolescents and young adults with lower agreeableness and conscientiousness seem to be less affected by the increased severity of self-perceived malocclusion, as demonstrated in reporting some psychosocial impacts.

    There is increasing pressure for reduction of user fees, but this can have adverse effects by decreasing facility-level funds. To address this, direct facility funding (DFF) was piloted in Coast Province, Kenya, with health facility committees (HFCs) responsible for managing the funds. We evaluated the implementation and perceived impact 2.5 years after DFF introduction. Quantitative data collection at 30 public health centres and dispensaries included a structured interview with the in-charge, record reviews and exit interviews. In addition, in-depth interviews were conducted with the in-charge and HFC members at 12 facilities, and with district staff and other stakeholders. DFF procedures were well established: HFCs met regularly and accounting procedures were broadly followed. DFF made an important contribution to facility cash income, accounting for 47% in health centres and 62% in dispensaries. The main items of expenditure were wages for support staff (32%), travel (21%), and construction and maintenance (18%). DFF was perceived to have a highly positive impact through funding support staff such as cleaners and patient attendants, outreach activities, renovations, patient referrals and increasing HFC activity. This was perceived to have improved health worker motivation, utilization and quality of care. A number of problems were identified. HFC training was reportedly inadequate, and no DFF documentation was available at facility level, leading to confusion. Charging user fees above those specified in the national policy remained common, and understanding of DFF among the broader community was very limited. Finally, relationships between HFCs and health workers were sometimes characterized by mistrust and resentment. Relatively small increases in funding may significantly affect facility performance when the funds are managed at the periphery. Kenya plans to scale up DFF nationwide. Our findings indicate this is warranted, but should include improved training

    This paper reports on the outcomes of a locally designed educational programme to support leadership capability of junior registered nurses. The Developing Leader Programme is an in-house programme delivered in three face-to-face workshops, comprising self-directed reflective and application activities. Surveys were used to evaluate self-perceived leadership capability over a 9-month period. The survey comprised a Leadership Capability Instrument adapted from two existing tools. Participants completed surveys at the commencement of the programme, after the third and final workshop and approximately 6 months afterwards. In addition, examples of descriptive accounts of programme activities submitted by individual participants were included to enrich data. Of 124 participants, 79 completed surveys at the first workshop, 28 at the final workshop and 31 were returned 6 months after completion of the programme. Mean scores for each area of leadership capability significantly improved throughout the duration of the programme (P leadership behaviours through reported activities. Survey responses indicated that participants perceived improved leadership capability after completing the Developing Leader Programme. Early educational intervention to facilitate the development of leadership skills as well as clinical skills in junior registered nurses can assist with how they interact with the team.

    This study on competition in human groups was performed within the context of the competitive outcome interdependence concept: the degree to which personal outcomes among group members are affected by the consequences of task performance of others, e.g. when one group member gains a high reward for a task, this lowers the available reward for other group members. Our computer-based multi-participant game empirically assessed how competitive versus neutral conditions influenced the reward-maximising behaviour of 200 undergraduate students functioning in ten-person groups - each playing two games (1 neutral and 1 competitive), their perceived pay satisfaction as well as perceived stress levels and sense of calmness within the games' task to search for coins. Participants were represented by black dots moving on a virtual playground. Results showed that competition led to reward-maximising but fellow group member disadvantaging behaviour, and all participants experienced lower pay satisfaction, higher stress levels and less calmness. We conclude that short-term behavioural consequences of positive individual competitive behaviour were gained at the above-mentioned potential long-term negative costs for all group members. This implies group paradigms aimed at sustainability should avoid introducing competitive factors that at best result in short-lived gains and at worst cause widespread dissatisfaction, stress and a pervasive lack of calmness.

    This study examines how life satisfaction changes as a function of the transition into retirement, distinguishing between different types of voluntary and involuntary exits. Perceived satisfaction with life (SWL) was measured among 1,388 older Dutch workers on two occasions, separated by 6 years. During that time, more than half of participants (54%) left full-time employment and entered retirement. Those who made a voluntarily departure from the workforce reported higher levels of perceived SWL compared with those who remained employed, whereas the life satisfaction scores of those whose departure was involuntary (due to health reasons, organizational reasons) were found to be the lowest. Other factors that had an effect on satisfaction included positive and negative health changes experienced during the 6-year interim, as well as changes in marital status due to divorce or loss of a spouse. These findings have important theoretical implications for the understanding of factors that shape individuals' perceptions of how they view the quality of their lives. From an applied perspective, the findings have implications for the development of organizational initiatives aimed at helping workers transition into retirement in such a way as to maintain high levels of subjective well-being.

    This study aimed to assess the impact of target faces' skin tone and perceivers' skin tone on the participants' attractiveness judgment regarding a symmetrical representative range of target faces as stimuli. Presented with a set of facial features, 240 Mozambican adults rated their attractiveness along a continuous scale. ANOVA and Chi-square were used to analyze the data. The results revealed that the skin tone of the target faces had an impact on the participants' attractiveness judgment. Overall, participants preferred light-skinned faces over dark-skinned ones. This finding is not only consistent with previous results on skin tone preferences, but it is even more powerful because it demonstrates that the light skin tone preference occurs regardless of the symmetry and baseline attractiveness of the stimuli.

    The use of ePortfolios has been implemented in several regulatory organizations to encourage clinicians' engagement in continuing professional development (CPD). However, their use has achieved mixed success, and multiple personal and contextual factors can influence their impacts on practice change. The aim of this study was to identify which factors influence the acceptability and perceived impacts of an ePortfolio implemented by an occupational therapy regulatory organization in one Canadian province. A cross-sectional online survey design was used. The survey was sent to registered occupational therapists in Quebec. Multiple regression analyses were conducted to identify factors influencing acceptability and outcomes: ease of use, satisfaction, impact on implementation of the CPD plan, and competence improvement. The survey was fully completed by 546 participants. Factors significantly influencing the ePortfolio acceptability and perceived impacts were attitude toward and familiarity with the portfolio, confidence in reflective skills, engagement in the CPD plan, and desire for feedback. Time spent completing the ePortfolio and the fact of completing it in teams were negatively associated with the outcomes. Shaping more favorable user attitudes, helping users recognize and experience the tool's benefits for their practice, and fostering confidence in their reflective skills are important factors that can be addressed to improve ePortfolio acceptability and outcomes. Contextual factors, such as time spent completing the ePortfolio and completing it in teams, seem to reflect greater difficulty with using the tool. Study findings can contribute to improving ePortfolio implementation in the CPD context.

    To explore the perceived impact among a group of Scottish 16- and 17-year-old school leavers of the recent increase in age of sale of cigarettes (1 October 2007) from 16 to 18 years on their ability to purchase and access cigarettes. Qualitative interviews with friendship pairs. Twelve paired qualitative interviews conducted in June 2008. Participants were 16- and 17-year-old early school leavers undertaking a work skills programme in Lothian who smoked at least one cigarette per week. Data were analysed thematically. The increase in the age of sale affected participants' perceived ability to purchase cigarettes to differing extents. Three groups were identified: those who were unable to purchase cigarettes either before or after the change in the law, those who could purchase cigarettes before the change in the law but who found it very difficult to do so afterwards, and those who were relatively unaffected as they could purchase cigarettes both before and after the age was raised to 18 years, mostly from small corner shops. Smoking was embedded in participants' social lives and networks. Thus, there was only a limited impact upon their reported ability to access cigarettes due to the availability of alternative social sources of cigarettes from family, friends and others. This exploratory study raises questions about the nature and extent of the impact of raising the age of sale on young smokers' ability to purchase and access cigarettes. The importance of alternative social sources of cigarettes highlights the need for further research to investigate whether the change in legislation had less of an impact on more disadvantaged adolescent smokers, as they are likely to have greater access to alternative sources from their family, friends and community.

    Full Text Available Abstract Background To determine the prevalence, intensity and extent of the Oral Impacts on Daily Performances associated with self-perceived malocclusion among Peruvian schoolchildren. Methods Eight hundred and five children aged 11 to 12 years attending 4 of 7 randomly selected schools linked to a Health Centre in Lima, Peru, participated in the study. The Spanish (PeruChild-OIDP was used to assess the prevalence, intensity and extent of oral impacts on 8 daily performances (eating, speaking, teeth cleaning, sleeping, smiling, studying, emotion and social contact. Self-perceived malocclusion included complaints about position of teeth, spacing of teeth and deformity of mouth or face. The prevalence of oral impacts was compared by covariables using the Chi-square test, whereas the intensity and extent of oral impacts were compared by covariables through the Mann-Whitney test. Results Only 15.5% of children reported impacts associated with self-perceived malocclusion during the last 3 months. Of them, 18.4% reported impacts of severe or very severe intensity and 76.0% reported impacts on only one daily performance. Psychosocial activities such as smiling, emotion and social contact were the most frequently and severely impacted everyday activities. Conclusion Impacts of self-perceived malocclusion primarily affected psychological and social everyday activities. These findings provide further evidence to support the importance of psychological and social components of oral health on children's lives.

  15. Misconceptions and constraints

    In theory, the sterile insect technique (SIT) is applicable to a wide variety of invertebrate pests. However, in practice, the approach has been successfully applied to only a few major pests. Chapters in this volume address possible reasons for this discrepancy, e.g. Klassen, Lance and McInnis, and Robinson and Hendrichs. The shortfall between theory and practice is partly due to the persistence of some common misconceptions, but it is mainly due to one constraint, or a combination of constraints, that are biological, financial, social or political in nature. This chapter's goal is to dispel some major misconceptions, and view the constraints as challenges to overcome, seeing them as opportunities to exploit. Some of the common misconceptions include: (1) released insects retain residual radiation, (2) females must be monogamous, (3) released males must be fully sterile, (4) eradication is the only goal, (5) the SIT is too sophisticated for developing countries, and (6) the SIT is not a component of an area-wide integrated pest management (AW-IPM) strategy. The more obvious constraints are the perceived high costs of the SIT, and the low competitiveness of released sterile males. The perceived high up-front costs of the SIT, their visibility, and the lack of private investment (compared with alternative suppression measures) emerge as serious constraints. Failure to appreciate the true nature of genetic approaches, such as the SIT, may pose a significant constraint to the wider adoption of the SIT and other genetically-based tactics, e.g. transgenic genetically modified organisms (GMOs). Lack of support for the necessary underpinning strategic research also appears to be an important constraint. Hence the case for extensive strategic research in ecology, population dynamics, genetics, and insect behaviour and nutrition is a compelling one. Raising the competitiveness of released sterile males remains the major research objective of the SIT. (author)

    The effect of facially applied air movement on perceived air quality (PAQ) at high humidity was studied. Thirty subjects (21 males and 9 females) participated in three, 3-h experiments performed in a climate chamber. The experimental conditions covered three combinations of relative humidity and local air velocity under a constant air temperature of 26 C, namely: 70% relative humidity without air movement, 30% relative humidity without air movement and 70% relative humidity with air movement under isothermal conditions. Personalized ventilation was used to supply room air from the front toward the upper part of the body (upper chest, head). The subjects could control the flow rate (velocity) of the supplied air in the vicinity of their bodies. The results indicate an airflow with elevated velocity applied to the face significantly improves the acceptability of the air quality at the room air temperature of 26 C and relative humidity of 70%.

    Background: Immediate reporting, commonly referred to as a ‘hot reporting’, has been advocated as a method of effectively supporting clinical decision making. However, its implementation nationally has been limited with poor understanding of its value in practice. Method: A cross sectional attitudinal survey was distributed to emergency department clinicians (medical and nursing staff) and radiographers to explore perceptions of an immediate reporting service in terms of its influence on professional role and autonomy, patient care and service quality. Results: A total of 87 (n = 87/155; 56.1%) completed questionnaires were returned. The findings suggest that significant support for immediate reporting exists. Immediate reporting is believed to improve service quality, reduce clinical errors and provide opportunity for image interpretation skills development. However, responses were not consistent across clinical professions and staff grades. Conclusion: The immediate reporting of emergency department images is perceived to benefit patient, emergency department clinicians and hospital organisation

    Recent literature suggests that middle manager affective commitment (emotional attachment, identification, and involvement) to an improvement program may influence implementation success. However, less is known about the interplay between middle manager affective commitment and frontline worker commitment, another important driver of implementation success. We contribute to this research by surveying middle managers who directly manage frontline workers on nursing units. We assess how middle manager affective commitment is related to their perceptions of implementation success and whether their perceptions of frontline worker support mediate this relationship. We also test whether a set of organizational support factors foster middle manager affective commitment. We adapt survey measures of manager affective commitment to our research context of hospitals. We surveyed 67 nurse managers from 19 U.S. hospitals. We use hierarchical linear regression to assess relationships among middle manager affective commitment to their units' falls reduction program and their perceptions of three constructs related to the program: frontline worker support, organizational support, and implementation success. Middle manager affective commitment to their unit's falls reduction program is positively associated with their perception of implementation success. This relationship is mediated by their perception of frontline worker support for the falls program. Moreover, middle managers' affective commitment to their unit's falls program mediates the relationship between perceived organizational support for the program and perceived implementation success. We, through this research, offer an important contribution by providing empirical support of factors that may influence successful implementation of an improvement program: middle manager affective commitment, frontline worker support, and organizational support for an improvement program.

Residents’ perception of sustainable tourism development potential, sense of place, perceived tourism impacts, and tourism development support were involved in this study. A total of 331 completed questionnaire surveys were collected in Luozhou, a historical-cultural village in China. The empirical data were analyzed using a structural equation modeling (SEM technique, and the results revealed that perceived collective benefits had a significant positive effect on tourism development support, whereas the other three perceived impacts’ influence were not significant. The relationship between residents’ sense of place and perceived collective and personal benefits, perceived personal costs and tourism development support, were significant. Additionally, residents’ perceptions of tourism development potential had a significant influence on perceived impact and tourism development support except for perceived personal benefits. Some practical implications of those findings for tourism planning and development are also discussed.

    Adults with congenital heart disease seem to be more distressed than their healthy counterparts, which might render them even more susceptible to developing detrimental health outcomes. Previous research has confirmed the relationship between the perceived impact of stress on health and self-rated health. However, it remains unknown whether sense of coherence, a person's capacity to cope with stressors, moderates this relationship. This cross-sectional study aims to explore: the relationship between demographic and clinical characteristics, sense of coherence, and the perceived impact of stress on health; the relationship between the perceived impact of stress on health and self-rated health; and the moderating effect of sense of coherence in a sample of adults with congenital heart disease. Patients were recruited from the database of congenital and structural cardiology of a university hospital. The analytic sample included 255 patients (median age 35 years; 50% men). Data were obtained using self-report questionnaires and through medical record view. Univariate analyses and multiple regression analysis were conducted. The perceived impact of stress on health was negatively associated with sense of coherence (Pstress on health and self-rated health were negatively associated (Prelationship. Our findings support the need for further research on the perceived impact of stress on health. Such insights can be valuable for developing interventions aimed at reducing the negative health consequences of stress in patients with congenital heart disease. © The European Society of Cardiology 2015.

    Human activities extract and displace different substances and materials from the earthAEs crust, thus causing various environmental problems, such as climate change, acidification and eutrophication. As problems have become more complicated, more holistic measures that consider the origins and sources of pollutants have been called for. Industrial ecology is a field of science that forms a comprehensive framework for studying the interactions between the modern technological society and the environment. Industrial ecology considers humans and their technologies to be part of the natural environment, not separate from it. Industrial operations form natural systems that must also function as such within the constraints set by the biosphere. Industrial symbiosis (IS) is a central concept of industrial ecology. Industrial symbiosis studies look at the physical flows of materials and energy in local industrial systems. In an ideal IS, waste material and energy are exchanged by the actors of the system, thereby reducing the consumption of virgin material and energy inputs and the generation of waste and emissions. Companies are seen as part of the chains of suppliers and consumers that resemble those of natural ecosystems. The aim of this study was to analyse the environmental performance of an industrial symbiosis based on pulp and paper production, taking into account life cycle impacts as well. Life Cycle Assessment (LCA) is a tool for quantitatively and systematically evaluating the environmental aspects of a product, technology or service throughout its whole life cycle. Moreover, the Natural Step Sustainability Principles formed a conceptual framework for assessing the environmental performance of the case study symbiosis (Paper 1). The environmental performance of the case study symbiosis was compared to four counterfactual reference scenarios in which the actors of the symbiosis operated on their own. The research methods used were process-based life cycle

    Full Text Available Aspects such as the growing importance of teamwork and the emergence of new organizational schemes based on information and communication technologies highlight the need for understanding the mechanisms that promote effective leadership. In this sense, this paper analyzes the determinants of perceived risk and trust on a team leader. The research consists of two experiments. The first analyzes the influence of working environment—virtual or traditional—on the two dependent variables considered. The second experiment focuses on the virtual environment and analyzes the importance of the inclusion of a photo on the electronic leader’s profile in order to generate trust. Moreover, it analyzes the impact of perceived leader traits (attractive or expert on the ability to build trust and the perception of risk. It shouldbe noted that these analyzes are contextualized in the initial stage of team development, poorly studied in the literature. Among others, the results reveal the greater difficulty of building trust in virtual environments, as well as the relevance of including graphical information on the profile and that the leader with expert traits has the greatest potential to buildtrust. These results have interesting managerial implications, which are discussed along with the main future research lines and limitations.

    Safety at work is a core issue for mental health staff working on in-patient units. At present, there is a limited theoretical base regarding which factors may affect staff perceptions of safety. This study attempted to identify which factors affect perceived staff safety working on in-patient mental health wards. A cross-sectional design was employed across 101 forensic and non-forensic mental health wards, over seven National Health Service trusts nationally. Measures included an online staff survey, Ward Features Checklist and recorded incident data. Data were analysed using categorical principal components analysis and ordinal regression. Perceptions of staff safety were increased by ward brightness, higher number of patient beds, lower staff to patient ratios, less dayroom space and more urban views. The findings from this study do not represent common-sense assumptions. Results are discussed in the context of the literature and may have implications for current initiatives aimed at managing in-patient violence and aggression.

    Consumer neuroscience can provide useful insights into the neural foundations of consumer decisions, such as perceived quality. One of the applications is to guide attribute configuration of products to fit consumers' expectations on the basis of individual preferences. In this study, we required 20 participants to decide whether to buy the product provided in the stimuli and to respond as soon as possible. According to their reports of expectations after the experiment, we subdivided the stimuli into two conditions. Condition 1 contained the stimuli that fit individual preferences, whereas Condition 2 contained the other stimuli. An essential component of event-related potentials (ERPs), the P300, was elicited in the two conditions and distributed over almost all parietal and occipital regions. Products in Condition 1 induced a higher P300 amplitude than those in Condition 2. The results show that evaluating product attributes is a cognitive process that modulates attention in the aforementioned regions. When participants evaluate the alternatives, categorical processing occurred on the basis of similarity judgment. The situation in Condition 1 produced a similarity overlap between the product and the expectation and resulted in a higher P300. Otherwise, there was no overlap, leading to a smaller P300. Hence, the P300 may be a useful neural endogenous indicator for measuring consumers' evaluations of products in marketing research.

    The perceived temperature (PT) is a measure for the quantification of human thermal comfort developed by the German Meteorological Service (DWD). In the present article, the sensitivity of PT on air temperature, water vapour pressure, wind speed, mean radiant temperature, street canyon width, and building heights is investigated. The mesoscale atmospheric model METRAS is integrated for a domain covering the city of Hamburg at 250 m horizontal resolution to calculate the meteorological input data for PT. The sensitivities of PT are determined by automatic differentiation of the basic DWD program. The sensitivities show how local adaptation measures and regional climate change can influence PT. The sensitivities also allow to estimate how accurate different input variables need to be known in order to achieve a desired accuracy in PT. The results are discussed in detail for 10 June 2007, a cloudless day with advection of warm air masses from south-east. A comparison with results obtained for different synoptic situations during summer is made. The sensitivities of PT on air temperature, water vapour pressure and mean radiant temperature are higher during warm and humid conditions than in situations with thermal comfort. The sensitivity of PT on wind speed is highest for low wind speeds. Around noon, increasing the building heights by 5 m can reduce PT up to 2.4 K due to shading effects in street canyons with aspect ratios above 0.5. After sunset, increasing the building heights by 5 m tends to moderately increase PT due to increased longwave radiation. (orig.)

    Full Text Available Incarcerated women enter the prison setting with remarkable histories of trauma, mental health and substance abuse issues. Given the stress of incarceration and separation from their children, families, and significant others, it is not surprising that many women experience increased anxiety, depression, and problems with sleep. Due to these negative outcomes, it is imperative to find efficient non-pharmacological interventions. This pilot study examined the impact of a 12-week mindfulness based program on the stress, anxiety, depression and sleep of women with a total of 33 completing the study. In one group, women’s perceived stress, anxiety and depression were all significantly lower following the intervention compared to prior to the intervention. Challenges with implementing the pilot study are addressed. Despite challenges and limitations, the low-cost non-pharmacological intervention has potential for a reducing the symptoms of anxiety and depression.

    Young people in low and middle income countries (LMICs) in societal transitions with rapidly changing norms face an increased risk of suicide. This study explores how young people in Cambodia understand the impact on suicidal behaviour from societal attitudes, media and religion. Focus group discussions were held with school students from a suburban area. Thematic analysis was used to interpret the data. Participants perceived the prevailing suicide-stigmatizing societal attitudes, the double-edged media and suicide-ambiguity in Buddhist religion as challenging. Globalization was recognized as contradicting with traditional Cambodian norms and values. Suicide prevention programmes should take into consideration the complex picture of suicide that young people are exposed to. © The Author(s) 2015.

    Full Text Available Abstract Background Although the promotion of mental health (MHP through education and training is widely accepted, there is scarce evidence for its effectiveness in the literature from outcome studies worldwide. The present study aimed to assess the effect of a three-semester MHP educational program on the recipients' opinions towards mental illness and on their own self-assessed health. Methods Respondents were 78 attendees who completed the assessment battery at the first (baseline and the last session (end of the training course. They were primary care physicians or other professionals, or key community agents, working in the greater Athens area. The course consisted of 44 sessions (4 h each, over a 3-semester period, focusing on the principles and methods of mental health promotion, the main aspects of major psychiatric disorders, and on relevant to health skills. Assessment instruments included the Opinion about Mental Illness (OMI scale and the General Health Questionnaire (GHQ-28. Results The mean scores of three OMI factors, that is, social discrimination, social restriction and social integration, and the two GHQ-28 subscales, that is, anxiety/insomnia and social dysfunction, were significantly improved by the end of the training course. Conclusions The results of this study provide evidence, with limitations, for the short-term effectiveness of the implemented educational MHP program on an adult group of recipients-key agents in their community. Because interventions for strengthening positive opinions about mental illness and enhancing self-assessed health constitute priority aims of mental health promotion, it would be beneficial to further investigate the sustainability of the observed positive changes. In addition it would be useful to examine (a the possible interplay between the two outcome measures, that is, the effect of opinions of recipients about mental health on their perceived health, and (b the applicability of this

    To describe staff nurses' perceptions related to the leadership styles adopted by their nurse managers, identify which leadership style ensured job satisfaction in staff nurses and describe which behaviours nurse managers should change. Empirical literature suggests that leadership styles of nurse managers significantly influence staff satisfaction. However, few studies investigate how staff nurses perceive the leadership styles of their nurse managers, and how these impact upon the staff nurses' job satisfaction. This was a mixed method study, which included the administration of the Multi-factor Leadership Questionnaire and three focus groups. Ward nurse managers mostly adopted a transactional leadership style ('Management by exception active') aimed at monitoring errors and intervening to correct errors and punish, which had a negative impact on staff nurses' levels of job satisfaction. In contrast, the transformational leadership style, which is mostly correlated with satisfaction ('Idealized Influence Attributed', which staff nurses perceived as 'respect', 'caring for others', 'professional development' and 'appreciation'), was rarely practiced by nurse managers. The transformational leadership skills of Italian nurse managers need to be improved through behaviours based on greater respect, caring for others, professional development and appreciation. The present study could also serve as model to improve the leadership style of nurse managers in other countries. The themes of transformational leadership could serve as a guide for nurse managers to help them improve their leadership style, and improve the levels of job satisfaction in staff nurses. Owing to the complexity and the importance of this issue, classroom educational interventions would not be sufficient: it should be dealt as a strategic priority by nursing directors. © 2016 John Wiley & Sons Ltd.

    This study aimed to develop a suitable instrument for a comprehensive quantitative and qualitative assessment of perceived psychosocial impact, levels of stress and learning effect in undergraduate dental students during the transition from pre-clinical to clinical education. These findings might improve curricular structures and didactic organisation during this period. At the beginning of their first clinical year, undergraduate dental students were asked to complete an anonymous forty-item questionnaire. Two hundred and seventy-six undergraduate dental students were willing to participate and completed the questionnaire and participated during the years 2011-2016. The response rate was between 45% and 96%. Correlational analysis (Spearman-Rho) in the field of psychosocial impact showed the dental teacher to be the most important multiplier of students' feelings. If the students feel that their teacher acts cooperatively, positive items increase and negative items decrease significantly (P < .0001). Also, students who report high levels of stress are affected significantly in their psychosocial interaction (P < .0001). Wilcoxon test yielded highest levels of stress in endodontology during the first weeks (P < .0001). During the same period, the greatest learning increment was seen for diagnostics and caries excavation. In conclusion, teaching of undergraduate dental students during the transition period from pre-clinical to clinical education can be positively influenced by a supportive learning environment and by specific chronological modifications in the curriculum. Students should start their clinical training with diagnostics, preventive dentistry and initial periodontal treatment. Due to high levels of perceived stress, endodontology should be introduced later in the clinical curriculum. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Objective: To assess how families perceive the positive and negative impacts of caring for a child with mental retardation. Methods: The quantitative descriptive study was conducted from January to August 2007 and comprised 54 families attending a private day-care centre for children with special needs in Karachi, Pakistan. The Kansas Inventory of Parental Perceptions was used to assess mothers' perceptions on the impact of caring for a child with mental retardation. Positive contributions, social comparisons with others, understanding of disability and perception of control were assessed. SPSS 16 was used for statistical analysis. Results: Mothers reported positive contribution to family life as a result of caring for a child with mental retardation (Mean: 2.95+-0.37). There was an acceptance of the situation and a trend towards upward favourable comparison with other families (Mean: 3.13+-0.07). Conclusions: Contrary to earlier studies exploring the impact of caring for a child with disabilities having largely focused on negative contributions, the study highlights some positive contributions.

    Abbatiello, James

    Human beings have an innate need to spend time outside, but in recent years children are spending less time outdoors. It is possible that this decline in time spent outdoors could have a negative impact on child development. Science teachers can combat the decline in the amount of time children spend outside by taking their science classes outdoors for regular classroom instruction. This study identified the potential impacts that learning in an outdoor setting might have on student engagement when learning middle school science. One sixth-grade middle school class participated in this case study, and students participated in outdoor intervention lessons where the instructional environment was a courtyard on the middle school campus. The outdoor lessons consisted of the same objectives and content as lessons delivered in an indoor setting during a middle school astronomy unit. Multiple sources of data were collected including questionnaires after each lesson, a focus group, student work samples, and researcher observations. The data was triangulated, and a vignette was written about the class' experiences learning in an outdoor setting. This study found that the feeling of autonomy and freedom gained by learning in an outdoor setting, and the novelty of the outdoor environment did increase student engagement for learning middle school science. In addition, as a result of this study, more work is needed to identify how peer to peer relationships are impacted by learning outdoors, how teachers could best utilize the outdoor setting for regular science instruction, and how learning in an outdoor setting might impact a feeling of stewardship for the environment in young adults.

    The purpose of this study was to assess if a clinical group practice model has an impact on enhancing the interpersonal skills of predoctoral dental students, what factors may influence the development of these skills, and what, if any, are innovative and technological solutions that can potentially influence interpersonal skills in predoctoral dental students. This study surveyed the faculty responsible for teaching the dental students in a recently developed group practice model. Out of 18 eligible group practice leaders at one US dental school, 17 respondents (94.4%) completed the survey. In addition, this study asked the faculty to provide qualitative response and recommendations to improve interpersonal skills. Based on the feedback, a focus group was conducted to explore opportunities to further enhance the skills. The results of the study suggest that the group practice model has a positive and distinct impact on the development of overall interpersonal skills for students. Further research suggests that the greatest impacted areas of personal development are critical thinking skills and teamwork. However, as a way to make the model more effectual, most faculty suggested the need for additional time, for both students and faculty. To some extent, using technology and innovative teaching pedagogies could potentially address the challenge of limited time. Based on the results of the survey, one may conclude that with adequate design and conditions, the group practice model can have a positive effect on the interpersonal skills of its students.

    This study investigated the impact of weight magnitude and distribution of body armour and carrying loads on military personnel's walking patterns and comfort perceptions. Spatio-temporal parameters of walking, plantar pressure and contact area were measured while seven healthy male right-handed military students wore seven different garments of varying weight (0.06, 9, 18 and 27 kg) and load distribution (balanced and unbalanced, on the front and back torso). Higher weight increased the foot contact time with the floor. In particular, weight placement on the non-dominant side of the front torso resulted in the greatest stance phase and double support. Increased plantar pressure and contact area observed during heavier loads entail increased impact forces, which can cause overuse injuries and foot blisters. Participants reported increasingly disagreeable pressure and strain in the shoulder, neck and lower back during heavier weight conditions and unnatural walking while wearing unbalanced weight distributed loads. This study shows the potentially synergistic impact of wearing body armour vest with differential loads on body movement and comfort perception. This study found that soldiers should balance loads, avoiding load placement on the non-dominant side front torso, thus minimising mobility restriction and potential injury risk. Implications for armour vest design modifications can also be found in the results.

    The aim of the European Board of Medical Genetics has been to develop and promote academic and professional standards necessary in order to provide competent genetic counselling services. The aim of this study was to explore the impact of the European registration system for genetic nurses and counsellors from the perspectives of those professionals who have registered. Registration system was launched in 2013. A cross-sectional, online survey was used to explore the motivations and experiences of those applying for, and the effect of registration on their career. Fifty-five Genetic Nurses and Counsellors are registered till now, from them, thirty-three agreed to participate on this study. The main motivations for registering were for recognition of their work value and competence (30.3%); due to the absence of a registration system in their own country (15.2%) and the possibility of obtaining a European/international certification (27.3%), while 27.3% of respondents registered to support recognition of the genetic counselling profession. Some participants valued the registration process as an educational activity in its own right, while the majority indicated the greatest impact of the registration process was on their clinical practice. The results confirm that registrants value the opportunity to both confirm their own competence and advance the genetic counselling profession in Europe.

    The current study examined the impact of the PROSPER delivery system for evidence-based prevention programs on multiple indicators of social capital in a rural and semi-rural community sample. Utilizing a randomized blocked design, 317 individuals in 28 communities across two states were interviewed at three time points over the course of 2.5 years. Bridging, linking, and the public life skills forms of social capital were assessed via community members' and leaders' reports on the perceptions of school functioning and the Cooperative Extension System, collaboration among organizations, communication and collaboration around youth problems, and other measures. Longitudinal mixed model results indicate significant improvements in some aspects of bridging and linking social capital in PROSPER intervention communities. Given the strength of the longitudinal and randomized research design, results advance prevention science by suggesting that community collaborative prevention initiatives can significantly impact community social capital in a rural and semi-rural sample. Future research should further investigate changes in social capital in different contexts and how changes in social capital relate to other intervention effects.

    The relationship between fatigue impact and walking capacity and perceived ability in patients with multiple sclerosis (MS) is inconclusive in the existing literature. A better understanding might guide new treatment avenues for fatigue and/or walking capacity in patients with MS. To investigate the relationship between the subjective impact of fatigue and objective walking capacity as well as subjective walking ability in MS patients. A cross-sectional multicenter study design was applied. Ambulatory MS patients (n = 189, age: 47.6 ± 10.5 years; gender: 115/74 women/men; Expanded Disability Status Scale (EDSS): 4.1 ± 1.8 [range: 0-6.5]) were tested at 11 sites. Objective tests of walking capacity included short walking tests (Timed 25-Foot Walk (T25FW), 10-Metre Walk Test (10mWT) at usual and fastest speed and the timed up and go (TUG)), and long walking tests (2- and 6-Minute Walk Tests (MWT). Subjective walking ability was tested applying the Multiple Sclerosis Walking Scale-12 (MSWS-12). Fatigue impact was measured by the self-reported modified fatigue impact scale (MFIS) consisting of a total score (MFIS total ) and three subscales (MFIS physical , MFIS cognitive and MFIS psychosocial ). Uni- and multivariate regression analysis were performed to evaluate the relation between walking and fatigue impact. MFIS total was negatively related with long (6MWT, r = -0.14, p = 0.05) and short composite (TUG, r = -0.22, p = 0.003) walking measures. MFIS physical showed a significant albeit weak relationship to walking speed in all walking capacity tests (r = -0.22 to -0.33, p < .0001), which persisted in the multivariate linear regression analysis. Subjective walking ability (MSWS-12) was related to MFIS total (r = 0.49, p < 0.0001), as well as to all other subscales of MFIS (r = 0.24-0.63, p < 0.001), showing stronger relationships than objective measures of walking. The physical impact of fatigue is weakly

    The foregoing has pointed out that the public had a false sense of security about TMI. The plant was designed to withstand an accident. What the public heard was that an accident could not happen. A lack of knowledge and misconceptions about nuclear reactors contributed to an interpretation that the accident would have a devastating effect on such things as real-estate, tourism, farming, infant mortality, health, business and jobs. This perception changed as data was reported. The community is alive and prospering. Some still have strong apprehensions. The drawn out cleanup process does not help. The large majority have learned to accept the presence of TMI and are assured that the impact has been more psychological than real

    Full Text Available It is well established that negative work-home interference (NegWHI impacts upon several work attitudes and behaviors. In the interests of both organizational effectiveness and employee well-being, it is important to identify concepts related to NegWHI and investigate their effects on well-being outcomes. This study examines the mediating role of (1 perceived organizational support (POS in the relationship between organizational justice (OJ and NegWHI; and (2 NegWHI in the relationships between POS and four well-being outcomes. A total of 509 employees of a Belgian hospital were surveyed. Data were analyzed using structural equation modeling and the bootstrapping method. Results showed that POS partially mediates the relationships between distributive and passive procedural justice and NegWHI, and fully mediates the relationship between the other justice dimensions and NegWHI. NegWHI partially mediates the relationships between POS and both job satisfaction and intention to quit, and fully mediates the relationship between POS and job strain. Furthermore, POS is positively related to job engagement. This study showed that organizations can help employees to better manage their work and family lives and reduce the impact of NegWHI by enhancing employees’ feeling that they are supported by their organization. In order to increase POS, organizations need to promote justice in the workplace.

    Background The aim of this study was to develop and conduct preliminary validation of the Perceived Impact of Problem Profile (PIPP). Based on the biopsychosocial model of health and functioning, the PIPP was intended as a generic research and clinical measurement tool to assess the impact and distress of health conditions from the individuals' perspective. The ICF classification system was used to guide the structure of the PIPP with subscales included to assess impact on self-care, mobility, participation, relationships and psychological well-being. While the ICF focuses on the classification of objective health and health related status, the PIPP broadens this focus to address the individuals' subjective experience of their health condition. Methods An item pool of 23 items assessing both impact and distress on five key domains was generated. These were administered to 169 adults with mobility impairment. Rasch analysis using RUMM2020 was conducted to assess the psychometric properties of each set of items. Preliminary construct validation of the PIPP was performed using the EQ5D. Results For both the Impact and Distress scales of the PIPP, the five subscales (Self-care, Mobility, Participation, Relationships, and Psychological Well-being) showed adequate psychometric properties, demonstrating fit to the Rasch model. All subscales showed adequate person separation reliability and no evidence of differential item functioning for sex, age, educational level or rural vs urban residence. Preliminary validity testing using the EQ5D items provided support for the subscales. Conclusion This preliminary study, using a sample of adults with mobility impairment, provides support for the psychometric properties of the PIPP as a potential clinical and research measurement tool. The PIPP provides a brief, but comprehensive means to assess the key ICF components, focusing on the individuals' perspective of the impact and distress caused by their health condition. Further

    Full Text Available Facial expression and gaze direction play an important role in social communication. Previous research has demonstrated the perception of anger is enhanced by direct gaze, whereas, it is unclear whether perception of fear is enhanced by averted gaze. In addition, previous research has shown the anxiety affects the processing of facial expression and gaze direction, but hasn’t measured or controlled for depression. As a result, firm conclusions cannot be made regarding the impact of individual differences in anxiety and depression on perceptions of face expressions and gaze direction. The current study attempted to reexamine the effect of the anxiety level on the processing of facial expressions and gaze direction by matching participants on depression scores. A reliable psychophysical index of the range of eye gaze angles judged as being directed at oneself [the cone of direct gaze (CoDG] was used as the dependent variable in this study. Participants were stratified into high/low trait anxiety groups and asked to judge the gaze of angry, fearful, and neutral faces across a range of gaze directions. The result showed: (1 the perception of gaze direction was influenced by facial expression and this was modulated by trait anxiety. For the high trait anxiety group, the CoDG for angry expressions was wider than for fearful and neutral expressions, and no significant difference emerged between fearful and neutral expressions; For the low trait anxiety group, the CoDG for both angry and fearful expressions was wider than for neutral, and no significant difference emerged between angry and fearful expressions. (2 Trait anxiety modulated the perception of gaze direction only in the fearful condition, such that the fearful CoDG for the high trait anxiety group was narrower than the low trait anxiety group. This demonstrated that anxiety distinctly affected gaze perception in expressions that convey threat (angry, fearful, such that a high trait anxiety

    judged each speech sample using the perceptual construct of Speech Severity using a visual analog scale. Additional measures obtained to describe participants included the Sentence Intelligibility Test (SIT), the 10-item Communication Participation Item Bank (CPIB), and standard biopsychosocial measures of depression (Beck Depression Inventory-Fast Screen; BDI-FS), fatigue (Fatigue Severity Scale; FSS), and overall disease severity (Expanded Disability Status Scale; EDSS). Healthy controls completed all measures, with the exception of the CPIB and EDSS. All data were analyzed using standard, descriptive and parametric statistics. For the MSCI group, the relationship between neuropsychological test scores and speech-language variables were explored for each speech task using Pearson correlations. The relationship between neuropsychological test scores and Speech Severity also was explored. Results and Discussion: Topic familiarity for descriptive discourse did not strongly influence speech production or perceptual variables; however, results indicated predicted task-related differences for some spoken language measures. With the exception of the MSCI group, all speaker groups produced the same or slower global speech timing (i.e., speech and articulatory rates), more silent and filled pauses, more grammatical and longer silent pause durations in spontaneous discourse compared to reading aloud. Results revealed no appreciable task differences for linguistic complexity measures. Results indicated group differences for speech rate. The MSCI group produced significantly faster speech rates compared to the MSDYS group. Both the MSDYS and the MSCI groups were judged to have significantly poorer perceived Speech Severity compared to typically aging adults. The Task x Group interaction was only significant for the number of silent pauses.

    Background In 2008, the Centers for Medicare and Medicaid Services (CMS) ceased additional payment for hospitalizations resulting in complications deemed preventable, including several health care-associated infections. We sought to understand the impact of the CMS payment policy on infection prevention efforts. Methods A national survey of infection preventionists from a random sample of US hospitals was conducted in December 2010. Results Eighty-one percent reported increased attention to HAIs targeted by the CMS policy, whereas one-third reported spending less time on nontargeted HAIs. Only 15% reported increased funding for infection control as a result of the CMS policy, whereas most reported stable (77%) funding. Respondents reported faster removal of urinary (71%) and central venous (50%) catheters as a result of the CMS policy, whereas routine urine and blood cultures on admission occurred infrequently (27% and 13%, respectively). Resource shifting (ie, less time spent on nontargeted HAIs) occurred more commonly in large hospitals (odds ratio, 2.3; 95% confidence interval: 1.0–5.1; P = .038) but less often in hospitals where front-line staff were receptive to changes in clinical processes (odds ratio, 0.5; 95% confidence interval: 0.3–0.8; P = .005). Conclusion Infection preventionists reported greater hospital attention to preventing targeted HAIs as a result of the CMS nonpayment policy. Whether the increased focus and greater engagement in HAI prevention practices has led to better patient outcomes is unclear. PMID:22541855

    Full Text Available There is heightened interest in identifying the impact of the federally-funded Public Health Training Center (PHTC program. Although evaluation studies have been conducted of public health training in general, evaluations of PHTC programs are rare. Field placement components are Congressionally-mandated requirements of PHTCs. Field placements are typically intensive, supervised externships for students to gain public health experience with local health departments or non-profit organizations. We have found no published evaluations of PHTC field placement components. This may be because of their small size and unique nature. We designed and evaluated a 200-hour field placement program at an established Public Health Training Center. The evaluation included pre/post surveys measuring public health core competencies, and post-experience interviews. We found significant increases in three competency domains among trainees: policy development and program planning, communication skills, and community dimensions of practice. These outcomes contribute to an evidence base on the efficacy of PHTC field placement programs, and underscore their role in public health training.

    Full Text Available In the last two decades, the medical understanding of Cystic Fibrosis (CF has dramatically improved, however, there are still significant gaps in our understanding of the psychological adjustment of families coping with CF. We examined the utility of the Social Cognitive Processing (SCP Model in understanding the interactions of parents and young people with CF. We also examined the relationship between social constraints, a key construct in the SCP model, sense of coherence (SOC and other psychological adjustment indicators for young people with CF. Participants comprised 49 individuals with CF, aged 16–25, recruited through state-based CF organisations in Australia. The results indicated that participant ratings of difficulties with communication (social constraints were positively associated with ratings of depression, anxiety, and stress and negatively related to ratings of positive affect and seeing life challenges as predictable, manageable and meaningful (SOC. Ratings of SOC were also positively related to ratings of positive affect and negatively related to ratings of depression, anxiety and stress. A significant mediating effect of SOC was also identified in the relationships between social constraints and positive affect and social constraints and stress. The theoretical and clinical implications of these findings are discussed.

    energetic (reported by 68%) and more active during the day (62%), being able to control their life (67%), proving themselves they could quit (60%), saving money (60%), as well being less worried about their health (57%) were also reported as motivations to quit cannabis use. Different coping and adaptation strategies were also reported. First, environmental strategies such as disposing of both cannabis (71%) and equipment to smoke (71%), no longer going to places where cannabis is smoked (33%) or lifestyle changes (68%) were used to cope with cannabis cessation. Then cognitive strategies such as motivation, willingness (71%), self-control and having a positive perception of the situation (68%) were also reported. Regarding coping strategies, participants accepted and learned how to live with the new situation (68%), and social support from family (32%) and friends (30%) were reported. Perceived benefits were linked with motivations for cannabis cessation. Thus, participants reported having more energy (75%), being more active (73%), less tired (70%) and recovering memory (57%) after cannabis cessation. Fifty-two percent of participants relapsed after the quit attempt. Abstainers had significantly higher scores on two subscales: the "negative impact of cannabis use on one's health and on self and social image" (t(61)=-3.84; Pchange, relapse, and abstinence. Social and family support, as well as social network appears to be of prime importance in relapses and prevention programs for cannabis use. New perspectives for research on cannabis cessation self-change and relapses are thus highlighted, notably regarding factors that could predict relapse or success in cessation of smoking cannabis. Research on cannabis self-change and relapse are warranted for both prevention and therapeutic programs. Copyright © 2013 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

    Objective To explore areas of consensus and conflict in relation to perceived public involvement (PI) barriers and drivers, perceived impacts of PI and ways of evaluating PI approaches in health and social care research. Background Internationally and within the UK the recognition of potential benefits of PI in health and social care research is gathering momentum and PI is increasingly identified by organisations as a prerequisite for funding. However, there is relatively little examination of the impacts of PI and how those impacts might be measured. Design Mixed method, three-phase, modified Delphi technique, conducted as part of a larger MRC multiphase project. Sample Clinical and non-clinical academics, members of the public, research managers, commissioners and funders. Findings This study found high levels of consensus about the most important barriers and drivers to PI. There was acknowledgement that tokenism was common in relation to PI; and strong support for the view that demonstrating the impacts and value of PI was made more difficult by tokenistic practice. PI was seen as having intrinsic value; nonetheless, there was clear support for the importance of evaluating its impact. Research team cohesion and appropriate resources were considered essential to effective PI implementation. Panellists agreed that PI can be challenging, but can be facilitated by clear guidance, together with models of good practice and measurable standards. Conclusions This study is the first to present empirical evidence of the opinions voiced by key stakeholders on areas of consensus and conflict in relation to perceived PI barriers and drivers, perceived impacts of PI and the need to evaluate PI. As such it further contributes to debate around best practice in PI, the potential for tokenism and how best to evaluate the impacts of PI. These findings have been used in the development of the Public Involvement Impact Assessment Framework (PiiAF), an online resource which offers

    Previous reports have indicated that raising a child with Gilles de la Tourette syndrome (GTS) could be considered a stressful experience. Thus our study aimed to assess the impact of perceived stress (i.e. parental cognitive perception of their child's disorder) and social support (number of people surrounding the subject providing support) on coping strategies-defined as processes of restoring balance between excessive demands and inadequate resources-of parents having a child with GTS. Twenty-eight parents of 21 patients with GTS (aged 6 to 16years) completed questionnaires on perceived stress (ALE Scale), social support (SSQ6), coping strategies (WCC-R) and anxiety-depression (HAD). Principal component analysis showed a negative correlation between social support on one side and perceived stress and anxiety/depression on the other. Problem- and emotion-focused coping both correlated with social support, all of them being independent from perceived stress and anxiety/depression. Hierarchical ascendant classification showed three clusters of individuals in our parents' groups: i) those having high scores in perceived stress and anxiety-depression; ii) those having high scores in social support associated with low scores in perceived stress; iii) parents having lower than average scores on both problem- and emotion- focused coping and social support. Our results reinforce the need for developing training programs for parents with GTS children to better understand and tolerate the disorder to decrease their stress. Copyright © 2015 Elsevier Inc.

    Full Text Available Background and Objectives: Nowadays, with the appearance of competitive environment, quality of services is important. The sector of health has a special status compared with other sectors of services. Patients determine the quality of services that are provided by hospitals which are regarded as large and complex service organizations within the health system. The aim of this study was to investigate the relationship between perceived service quality, perceived services value, patients’ satisfaction, word of mouth advertising and tendency to patients’ return. Material and Methods: This study was a descriptive and functional and from aspect of results, is practical and was done by one cross-sectional and fieldwork. The sample of study of 135 health care receivers, who were referred at least once from Feiz eye clinic in Isfahan were selected by using Cochran formula and stratified with random sampling. The data collected with a questionnaire which its reliability and validity were confirmed. The collected data were analyzed with SPSS and Smart PLS2 software. Results: The findings showed that all indices have acceptable load factor. Perceived service quality had a significant positive impact on perceived value (0.57 and patient satisfaction (0.28. Perceived value had a significant positive effect on patients’ satisfaction and patients’ return. Also, patients’ satisfaction had effect on word of mouth advertising and word of mouth advertising had effect on the patients’ return. Conclusion: The results of the study indicated that perceived value and patients’ satisfaction meditate between the relationship of perceived service quality and patients’ return. In addition, the indirect effect of perceived value on patients’ return, with changeable mediation of patients’ satisfaction is more than direct effect. Also, among the variables, patients’ satisfaction had greatest effect on patients return.

    Conflict resolution skills are important for all healthcare professionals as conflict and mis-communication can have detrimental effects on decision-making, potentially impacting significantly on patient care, morbidity, and mortality. Interprofessional learning (IPL) has been found to increase collaboration and improve collegial relationships and hence may be an appropriate way to increase conflict resolution skills among healthcare graduates. This study examined transference of conflict resolution skills, motivation-to-learn, and attitudes to IPL of medical (n = 52) and nursing (n = 74) undergraduate students who undertook an IPL conflict resolution program. Results indicated that motivation-to-learn, attitudes to IPL, and transfer of conflict resolution skills were significantly related to each other, even when controlling for other variables, such as age and gender. When comparing the two groups, undergraduate nursing students were found to have statistically higher motivation-to-learn and transference of conflict resolution skills, and reported a more positive attitude to IPL than medical students. Some of these differences may be attributed to lack of clinical placements for medical students in the first half of their degree at their university, giving them less opportunity to apply the conflict resolution skills taught, as well as less contextual relevance. This may potentially affect their motivation-to-learn and attitude to IPL thus impacting on how they perceive the relevance of learning conflict resolution skills. Without the contextual relevancy of placements at the time of learning for medical students, the newly acquired conflict resolution skills are less likely to transfer to practice in an optimal fashion.

    Accurate tests of the theory of stellar structure and evolution are available from the Sun's observations. The solar constraints are reviewed, with a special attention to the recent progress in observing global solar oscillations. Each constraint is sensitive to a given region of the Sun. The present solar models (standard, low Z, mixed) are discussed with respect to neutrino flux, low and high degree five-minute oscillations and low degree internal gravity modes. It appears that actually there do not exist solar models able to fully account for all the observed quantities. (Auth.)

    Full Text Available Four studies specify how moral evaluations of the self regulate behavior aimed at restoring a moral reputation. We propose that people care about evaluations of themselves as moral or immoral because these are perceived as more consequential than other types of information. Therefore people are more inclined to restore their image after being negatively evaluated in terms of morality rather than competence. Studies 1 and 2 revealed that moral information was perceived as having a more enduring impact on one’s reputation, and was more strongly related to anticipated intra-group respect and self-views, than competence and sociability information. This perceived pervasiveness of moral (versus competence evaluations mediated intentions to justify and explain one’s behavior (Study 3. Study 4 finally showed that being seen as lacking in morality elicited threat and coping responses, which induced subsequent tendencies to repair one’s moral reputation.

    Women in Pakistan have been overlooked during and after the planning anti implementation of household energy projects for decades. The immediate impact of domestic household energy projects falls on the women first. Since women are the ones who deal mostly with energy at the domestic level A sample of 100 women users of solar cookers was selected randomly. Majority of the respondents were in the age group 30-55 years (80%) and possessed solar cooker for more than one year (74%). Nutritional aspects (preserving nutritive value and food flavors) environmental aspects (keeping environment clean) and economical aspects (saving fuel and money) were perceived at most beneficial. Personal benefits (saving of time me and convenience) ranked low under benefit. Situational constraints like no cooking after evening find seasonal use of the cooker were perceived as severe constraints followed by technical constraints (device not being durable) and personal constraints (shifting of device). The paper also highlights the modification desired in the design of the solar cooker. (author)

    With the entry to WRO and development of IT, banks in China are adjusting their competitive strategies to meet the competition. Internet banking has become a kind of strategic choice to response to the entry to WTO. Based on relevantly selective reviews of literature of strategy theory and research, a model is developed to study banks' strategic response to entry to WTO. According to a survey of 192 sets of questionnaires, this study finds that external pressure, business strategy and perceived benefits of Internet banking would influence banks' perceived increase in Internet banking investment. And banks'perceived increase in Internet banking investment has no difference between big banks and small banks.

    There are considerable incentives for the use of nuclear in preference to other sources for base load electricity generation in most of the developed world. These are economic, strategic, environmental and climatic. However, there are two potential constraints which could hinder the development of nuclear power to its full economic potential. These are public opinion and financial regulations which distort the nuclear economic advantage. The concerns of the anti-nuclear lobby are over safety, (especially following the Chernobyl accident), the management of radioactive waste, the potential effects of large scale exposure of the population to radiation and weapons proliferation. These are discussed. The financial constraint is over two factors, the availability of funds and the perception of cost, both of which are discussed. (U.K.)

    Concerns for health and social impacts have arisen as a result of Marcellus Shale unconventional natural gas development. Our goal was to document the self-reported health impacts and mental and physical health stressors perceived to result from Marcellus Shale development. Two sets of interviews were conducted with a convenience sample of community members living proximal to Marcellus Shale development, session 1 March-September 2010 (n = 33) and session 2 January-April 2012 (n = 20). Symptoms of health impacts and sources of psychological stress were coded. Symptom and stressor counts were quantified for each interview. The counts for each participant were compared longitudinally. Participants attributed 59 unique health impacts and 13 stressors to Marcellus Shale development. Stress was the most frequently-reported symptom. Over time, perceived health impacts increased (P = 0·042), while stressors remained constant (P = 0·855). Exposure-based epidemiological studies are needed to address identified health impacts and those that may develop as unconventional natural gas extraction continues. Many of the stressors can be addressed immediately.

  18. Controversy matters: Impacts of topic and solution controversy on the perceived credibility of a scientist who advocates.

    Lindsey Beall

    Full Text Available In this article, we focus on the potential influence of a scientist's advocacy position on the public's perceived credibility of scientists as a whole. Further, we examine how the scientist's solution position (information only, non-controversial, and controversial affects the public's perception of the scientist's motivation for sharing information about specific issues (flu, marijuana, climate change, severe weather. Finally, we assess how perceived motivations mediate the relationship between solution position and credibility. Using data from a quota sample of American adults obtained by Qualtrics (n = 2,453, we found that in some conditions advocating for a solution positively predicted credibility, while in one condition, it negatively predicted scientist credibility. We also found that the influence of solution position on perceived credibility was mediated by several motivation perceptions; most notably through perception that the scientist was motivated to: (a serve the public and (b persuade the public. Further results and implications are discussed.

    Full Text Available The translator’s role and responsibility are high in any act of interlingual communication, and even higher when irony, an indirect and deliberately elusive form of communication, is involved in the translation process. By allowing more than one possible interpretation, irony is inevitably exposed to the risk of being misunderstood. This paper attempts to capture the complexity of translating irony, making use of theoretical frameworks provided by literary studies and translation studies. It analyses if and how the types of irony, the literary genres and the cultural, normative factors, perceived as potential contextual constraints, have an impact on the translator’ choices in rendering irony in translation, taking illustrative examples from Jonathan Swift, Oscar Wilde, Aldous Huxley and David Lodge’s works.

    We have studied cloudy taenite, metallographic cooling rates, and shock effects in 30 H3-6 chondrites to elucidate the thermal and early impact history of the H chondrite parent body. We focused on H chondrites with old Ar-Ar ages (>4.4 Gyr) and unshocked and mildly shocked H chondrites, as strongly shocked chondrites with such old ages are very rare. Cooling rates for most H chondrites at 500 °C are 10-50 °C/Myr and do not decrease systematically with increasing petrologic type as predicted by the onion-shell model in which types 3-5 are arranged in concentric layers around a type 6 core. Some type 4 chondrites cooled slower than some type 6 chondrites and type 3 chondrites did not cool faster than other types, contrary to the onion-shell model. Cloudy taenite particle sizes, which range from 40 to 120 nm, are inversely correlated with metallographic cooling rates and show that the latter were not compromised by shock heating. The three H4 chondrites that were used to develop the onion-shell model, Ste. Marguerite, Beaver Creek, and Forest Vale, cooled through 500 °C at ⩾5000 °C/Myr. Our thermal modeling shows that these rates are 50× higher than could be achieved in a body that was heated by 26Al and cooled without disturbance by impact. Published Ar-Ar ages do not decrease systematically with increasing petrologic type but do correlate inversely with cloudy taenite particle size suggesting that impact mixing decreased during metamorphism. Metal and silicate compositions in regolith breccias show that impacts mixed material after metamorphism without causing significant heating. Impacts during metamorphism created Portales Valley and two other H6 chondrites with large metallic veins, excavated the fast-cooled H4 chondrites around 3-4 Myr after accretion, and mixed petrologic types. Metallographic data do not require catastrophic disruption by impact during cooling.

    Retaining perceptions of autonomy is a key component of successful aging. Perceived autonomy refers to the capacity to make and enact self-directed decisions. These perceptions are often threatened in older adults with multiple illnesses, when functional limitations resulting from these illnesses impede the enactment of self-directed decisions. Regional resources (in Germany specifically at the level of administrative districts) might counteract these impediments of autonomy. Economically stronger districts can provide more-concrete support resources for older adults, buffering the negative effect of functional limitations on self-perceived autonomy. This study assessed participants aged over 65 with 2 or more chronic conditions. In total, N = 287 provided data (Mage = 73.3, SD = 5.07), and n = 97 were women. Gross domestic product (GDP) per capita was used as a proxy measure of administrative district wealth in Germany. Hierarchical multilevel regression analyses with cross-level interactions were conducted. Results suggest that the detrimental effect of functional limitations on perceived autonomy is less pronounced for participants residing in higher GDP districts. Conversely, for participants in lower GDP districts, the effect is exacerbated. This finding suggests that districts with greater financial resources might be better able to invest in supports that promote and facilitate autonomy and, thus, provide a buffer against threats to individual perceived autonomy.

    It is well known that cancer patients' perception of social support is associated with their depressive symptoms and health-related quality of life. However, there have been little studies that compared the variates of cancer patients with the general population. We sought to compare differences in the level of perceived social support and the impact of perceived social support on depressive symptoms and health-related quality of life between cancer survivors and the general population. Data were collected from 1818 cancer patients treated at the National Cancer Center and regional cancer centers in South Korea. The control group of the general population was composed of 2000 individuals without cancer from community. Cancer patients reported significantly higher level of perceived social support than the general population, while they reported lower health-related quality of life and were more susceptible to depression. The positive associations of higher perceived social support with lower depressive symptoms, as well as with higher health-related quality of life, were stronger among cancer patients than among the general population. The interaction effect suggests that the impact of social support would be stronger among cancer patients than the general public. Thus, it would be beneficial to pay attention to providing social support to cancer patients, particularly to those who are more vulnerable. Furthermore, investigation of the most effective and efficient methods to deliver social support interventions would be worthwhile. © The Author 2017. Published by Oxford University Press.

    The aim of this study was to determine the influence of work conditions, psychosocial factors and perceived health on the association between the presence of a chronic health condition and (single-item) work ability among workers aged 45 years and older. In addition, we aimed to examine variables associated with work ability for workers with and without a chronic health condition separately. The data of this cross-sectional study were obtained from 5,247 workers aged 45 years and older in five different work sectors. Work ability was assessed with the first item of the Work Ability Index. The presence of a chronic health condition was assessed by self-report. Independent variables in the multivariable linear regression analysis were work conditions, psychosocial factors and perceived health status. The presence of a chronic health condition was negatively associated with work ability (B = -0.848). The strength of this association slightly attenuated after subsequently adding individual characteristics (B = -0.824), work conditions (B = -0.805) and more so after adding psychosocial factors (B = -0.704) and especially perceived health variables (B = -0.049) to the model. Variables associated with work ability for workers with and without a chronic health condition were similar. Perceived health and psychosocial factors, rather than work conditions, explained the association between the presence of a chronic health condition and work ability. Substantial differences in variables associated with work ability for workers with and without a chronic health condition were not found. Based on the lower mean scores for workers with a chronic health condition and work ability as well for predictors, these workers might have the most benefit by a policy focussing on enhancing these associated variables.

    The aim of this study was to describe the current state of nurses' shift work in Taiwan and how it affects nurses' stress, sleep quality and self-perceived health status. To enable the provision of 24-hour patient care, nurses need to work various shifts. Long-term shift work significantly affects nurses' overall physical and mental health. Nurses from four Chiayi County district hospitals in Taiwan (n = 266) participated in this cross-sectional study from August to September 2010. Demographics, work schedule forms, a stress checklist, a sleep-quality measure and a health-status measure were used to collect data. Independent t-test, one-way anova, Pearson's r, and hierarchical regression were applied for analysis. The results showed that regardless of the amount of shift work they performed, nurses reported moderate job stress, poor sleep quality and moderate self-perceived health. The following significant relationships were observed: job stress was inversely related to sleep quality, which was directly related to self-perceived health status. Hospital managers need to ensure more healthy shift work scheduling in order to improve nurses' clinical performance and personal health status, thereby also improving the quality of patient care. © 2012 John Wiley & Sons Ltd.

    The present study examined generational differences in the patterns and predictors of formal and informal mental health service utilization among a nationally representative sample of 1850 Asian Americans from the National Latino and Asian American Study. We focused on the effects of perceived need and relational factors on service utilization among 1st-, 1.5-, and 2nd-generation Asian Americans. Results of hierarchical logistic regression showed significant intergenerational differences. Specifically, 1.5-generation Asian Americans exhibited distinctive pattern of service use, with perceived need being associated with a higher likelihood of using formal mental health services, but only for those with high level of social support. First- and second-generation Asian Americans, on the other hand, perceived need was independently associated with formal service use, and a significant predictor of informal service use for first generation. Greater family conflict was also associated with greater use of formal and informal services for both first- and second generations. However, family cohesion was associated with only informal service use among first -generation Asian Americans. Implications for mental health service policy were discussed.

    Full Text Available The objective of this paper is to analyze the influence of the sources of motivation that lead companies to adopt a global standard of the Environmental Management System and the barriers found in the process, on the perceived benefits of the implementation and certification of the standard. To achieve the objectives proposed, primary data were collected using a survey questionnaire that was administered to a representative sample of companies certified as EMAS-Eco-Management and Audit Scheme of the Autonomous Community of Galicia (sample of 114 of the 255 companies. An extensive review of the academic literature published on ISO 14001 and EMAS about motivations, barriers and benefits was carried out in order to establish the working hypotheses that are analyzed using structural equation models as the statistical tool. The findings of this study show that the motivations positively affect the benefits derived from implementation, noting that the internal motivations (related to efficiency; improved performance, productivity and profitability have a stronger influence on the benefits than the external motivations (related to stakeholders’ social pressure. In addition, the motivations also affect the perceived barriers, and these affect the benefits negatively, i.e., the higher the barriers encountered, the lower the perceived benefits. The results obtained allow us to identify important implications for managers, which will help them establish management strategies in the field of environmental management.

    Study context: This paper is the third paper arising from a two year long, in-depth case study exploring various components of the role of consultant radiographers in the UK. This paper focuses particularly upon the perceived impact of the role and factors that support and hinder the role in practice. Methods: A longitudinal case study method was used to explore the role of consultant radiographers. Interviewing was informed and guided by a phenomenological approach to promote a deeper understanding of consultants' experiences in the role. Eight consultant radiographers participated, with six involved throughout the whole study. Over an 18 month period each of those six consultants was interviewed three times. Two consultants only participated in the first interview; these interviews are also reported here. A total of 20 interviews were conducted. Findings: Interviews explored the impact of the consultant role as perceived by consultants themselves, and encouraged individual reflection on factors which had both supported and hindered success therein. Analysis demonstrated that there was substantial variation in the experiences communicated yet, and without any exception, all consultants reported that the introduction of their role had been beneficial to service delivery and quality of patient care. A number of obstacles were outlined, as well as a range of support mechanisms. Recommendations are thus made as to how the consultant role might be more effectively supported in the future. - Highlights: • The perceived impact of the consultant radiographer role in practice. • Reflections upon what supported the consultants in their role. • Reflections upon what hindered the consultants in their role.

    The Chinese government has established compulsory targets to reduce sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions by 8% and 10%, respectively, during 2010-2015. In this study, the effect of the policy was evaluated by predicting the recovery of acidified forest soil in Chongqing, an area severely impacted by acid rain in southwest China. Since precipitation has decreased significantly in this area in recent years, the impact of drought on soil acidification was also considered. A dynamic acidification model, MAGIC, was used to predict future trends in soil chemistry under different scenarios for deposition reduction as well as drought. We found that the current regulation of SO2 emission abatement did not significantly increase soil water pH values, the Ca2+ to Al3+ molar ratio (Ca/Al), or soil base saturation to the level of 2000 before 2050. NOx emission control would have less of an effect on acidification recovery, while emission reduction of particulate matter could offset the benefits of SO2 reduction by greatly decreasing the deposition of base cations, particularly Ca(2+). Continuous droughts in the future might also delay acidification recovery. Therefore, more stringent SO2 emission control should be implemented to facilitate the recovery of seriously acidified areas in China. © 2013 Elsevier B.V. All rights reserved.

  17. System-Level Operational and Adequacy Impact Assessment of Photovoltaic and Distributed Energy Storage, with Consideration of Inertial Constraints, Dynamic Reserve and Interconnection Flexibility

    Full Text Available The growing penetration of solar photovoltaic (PV systems requires a fundamental understanding of its impact at a system-level. Furthermore, distributed energy storage (DES technologies, such as batteries, are attracting great interest owing to their ability to provide support to systems with large-scale renewable generation, such as PV. In this light, the system-level impacts of PV and DES are assessed from both operational and adequacy perspectives. Different control strategies for DES are proposed, namely: (1 centralised, to support system operation in the presence of increasing requirements on system ramping and frequency control; and (2 decentralised, to maximise the harnessing of solar energy from individual households while storing electricity generated by PV panels to provide system capacity on request. The operational impacts are assessed by deploying a multi-service unit commitment model with consideration of inertial constraints, dynamic reserve allocation, and interconnection flexibility, while the impacts on adequacy of supply are analysed by assessing the capacity credit of PV and DES through different metrics. The models developed are then applied to different future scenarios for the Great Britain power system, whereby an electricity demand increase due to electrification is also considered. The numerical results highlight the importance of interconnectors to provide flexibility. On the other hand, provision of reserves, as opposed to energy arbitrage, from DES that are integrated into system operation is seen as the most effective contribution to improve system performance, which in turn also decreases the role of interconnectors. DES can also contribute to providing system capacity, but to an extent that is limited by their individual and aggregated energy availability under different control strategies.

  18. Individual uncertainty and the uncertainty of science: The impact of perceived conflict and general self-efficacy on the perception of tentativeness and credibility of scientific information

    Full Text Available We examined in two empirical studies how situational and personal aspects of uncertainty influence laypeople’s understanding of the uncertainty of scientific information, with focus on the detection of tentativeness and perception of scientific credibility. In the first study (N = 48, we investigated the impact of a perceived conflict due to contradicting information as a situational, text-inherent aspect of uncertainty. The aim of the second study (N = 61 was to explore the role of general self-efficacy as an intra-personal uncertainty factor. In Study 1, participants read one of two versions of an introductory text in a between-group design. This text provided them with an overview about the neurosurgical procedure of deep brain stimulation (DBS. The text expressed a positive attitude toward DBS in one experimental condition or focused on the negative aspects of this method in the other condition. Then participants in both conditions read the same text that dealt with a study about DBS as experimental treatment in a small sample of patients with major depression. Perceived conflict between the two texts was found to increase the perception of tentativeness and to decrease the perception of scientific credibility, implicating that text-inherent aspects have significant effects on critical appraisal. The results of Study 2 demonstrated that participants with higher general self-efficacy detected the tentativeness to a lesser degree and assumed a higher level of scientific credibility, indicating a more naïve understanding of scientific information. This appears to be contradictory to large parts of previous findings that showed positive effects of high self-efficacy on learning. Both studies showed that perceived tentativeness and perceived scientific credibility of medical information contradicted each other. We conclude that there is a need for supporting laypeople in understanding the uncertainty of scientific information and that

    Full Text Available Lymphatic filariasis (LF infects approximately 120 million people worldwide. As many as 40 million have symptoms of LF disease, including lymphedema, elephantiasis, and hydrocele. India constitutes approximately 45% of the world's burden of LF. The Indian NGO Church's Auxiliary for Social Action (CASA has been conducting a community-based lymphedema management program in Orissa State since 2007 that aims to reduce the morbidity associated with lymphedema and elephantiasis. The objective of this analysis is to evaluate the effects of this program on lymphedema patients' perceived disability.For this prospective cohort study, 370 patients ≥14 years of age, who reported lymphedema lasting more than three months in one or both legs, were recruited from villages in the Bolagarh sub-district, Khurda District, Orissa, India. The World Health Organization Disability Assessment Schedule II was administered to participants at baseline (July, 2009, and then at regular intervals through 24 months (July, 2011, to assess patients' perceived disability. Disability scores decreased significantly (p<0.0001 from baseline to 24 months. Multivariable analysis using mixed effects modeling found that employment and time in the program were significantly associated with lower disability scores after two years of program involvement. Older age, female gender, the presence of other chronic health conditions, moderate (Stage 3 or advanced (Stage 4-7 lymphedema, reporting an adenolymphangitis (ADL episode during the previous 30 days, and the presence of inter-digital lesions were associated with higher disability scores. Patients with moderate or advanced lymphedema experienced greater improvements in perceived disability over time. Patients participating in the program for at least 12 months also reported losing 2.5 fewer work days per month (p<0.001 due to their lymphedema, compared to baseline.These results indicate that community-based lymphedema management programs

    Binary near-Earth asteroid (65803) Didymos is the target of the proposed NASA Double Asteroid Redirection Test (DART), part of the Asteroid Impact & Deflection Assessment (AIDA) mission concept. In this mission, the DART spacecraft is planned to impact the secondary body of Didymos, perturbing mutual dynamics of the system. The primary body is currently rotating at a spin period close to the spin barrier of asteroids, and materials ejected from the secondary due to the DART impact are likely to reach the primary. These conditions may cause the primary to reshape, due to landslides or internal deformation, changing the permanent gravity field. Here, we propose that if shape deformation of the primary occurs, the mutual orbit of the system would be perturbed due to a change in the gravity field. We use a numerical simulation technique based on the full two-body problem to investigate the shape effect on the mutual dynamics in Didymos after the DART impact. The results show that under constant volume, shape deformation induces strong perturbation in the mutual motion. We find that the deformation process always causes the orbital period of the system to become shorter. If surface layers with a thickness greater than ∼0.4 m on the poles of the primary move down to the equatorial region due to the DART impact, a change in the orbital period of the system and in the spin period of the primary will be detected by ground-based measurement.

    The aims of the this prospective study were to analyse physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women's perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages--at 10-12 weeks' gestation (T1) and 20-22 weeks' gestation (T2)--were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants' characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters.

    Providing high-quality teaching to residents during attending rounds is challenging. Reasons include structural factors that affect rounds, which are beyond the attending's teaching style and control. To develop a new evaluation tool to identify the structural components of ward rounds that most affect teaching quality in an internal medicine (IM) residency program. The authors developed a 10-item Ecological Momentary Assessment (EMA) tool and collected daily evaluations for 18 months from IM residents rotating on inpatient services. Residents ranked the quality of teaching on rounds that day, and questions related to their service (general medicine, medical intensive care unit, and subspecialty services), patient census, absenteeism of team members, call status, and number of teaching methods used by the attending. Residents completed 488 evaluation cards over 18 months. This found no association between perceived teaching quality and training level, team absenteeism, and call status. We observed differences by service (P service, census was no longer significant. Use of a larger variety of teaching methods was associated with higher perceived teaching quality, regardless of service or census (P for trend quality, but the results were also influenced by the type of teaching service. We found that, regardless of census or teaching service, attendings can improve their teaching by diversifying the number of methods used in daily rounds.

    Transgender and gender nonconforming (TGNC) persons have routinely experienced high rates of violence and discrimination. Discrimination in healthcare can affect the ability of TGNC persons to age successfully as it often deters them from seeking care. The purpose of this study was to determine if anticipation of bias from healthcare professionals, as well as other variables, predicted perceived successful aging in a sample of TGNC adults. A total of 384 (of the original 1963) participants older than 50 years completed the relevant parts of an 83-item online survey as part of the Trans MetLife Survey on Later-Life Preparedness and Perceptions in Transgender-Identified Individuals. Larger social support networks and higher levels of confidence that a healthcare professional will treat them with dignity and respect as a TGNC person at the end of their life were associated with increased odds of perceiving that they were aging successfully. With high rates of discrimination and prejudice toward TGNC persons in various contexts (e.g., healthcare, education, and housing), it is imperative that practitioners, researchers, policymakers, and institutions work together to eradicate healthcare disparities, promote social change, and support an environment that encourages successful aging. This calls for a coordinated, proactive outreach effort to put trust back into a system that has historically let down an entire subset of the population.

    Objectives: How do students experience and perceive the innovative undergraduate radiology curriculum at Ghent University, and what explains differences in student perception? Methods: A survey was presented to the 2008 cohort of students enrolled in the undergraduate medical curriculum at Ghent University. The survey focused on their experiences and perceptions in relation to the innovative undergraduate radiology teaching. Results and conclusion: The present research results point at a favorable perception of the innovative radiology curriculum components. The study points - both during pre-clinical and clinical years - at the appreciation for curriculum components that combine traditional curriculum components (ex-cathedra lessons with syllabus) with distance learning components such as E-learning and E-testing. In clinical years - as expected - students switch to the application of knowledge and skills and therefore heavily appreciate practice linked curriculum components.

    While previous studies have examined motivational aspects of self-directed violence, few studies have included specific motivations in predictive models for future suicide attempts. The current study utilized a sample of 160 individuals treated in an acute emergency setting following a suicide attempt who completed an interview battery that included an assessment of functional aspects of the index suicide attempt. A follow-up interview was conducted at 6 months to ascertain subsequent suicide attempts. The functional domains of suicide attempts were labeled as reduction-of-distress, communication, perceived better alternative to living, and self-loathing. Above and beyond other known risk factors, including history and highest lethality of previous self-injury, suicide attempts that served a communication function (OR = 0.18, p = .02, CI = 0.04, 0.73) and higher ratings of clinical dysfunction (OR = 3.41, p = .05, CI = 1.02, 11.36) were associated with a significant reduction in likelihood to engage in a suicide attempt during the 6-month follow-up window. Including the perceived effectiveness of the index suicide attempt in getting one's needs met strengthened the overall model predicting a suicide attempt in the follow-up window and was an independent risk factor above and beyond other variables in the model OR = 1.75, p = .04, CI = 1.02, 3.01). Assessment of functional aspects of suicide attempt is feasible and may improve formulation of risk in a population where typical risk factors for suicide are ubiquitous. Copyright © 2016.

    Objective To evaluate the effect of anatomy-specific virtual reality (VR) surgical rehearsal on surgeon confidence and temporal bone dissection performance. Study Design Prospective pre- and poststudy of a novel virtual surgical rehearsal platform. Setting Academic otolaryngology-head and neck surgery residency training programs. Subjects and Methods Sixteen otolaryngology-head and neck surgery residents from 2 North American training institutions were recruited. Surveys were administered to assess subjects' baseline confidence in performing 12 subtasks of cortical mastoidectomy with facial recess. A cadaver temporal bone was randomly assigned to each subject. Cadaver specimens were scanned with a clinical computed tomography protocol, allowing the creation of anatomy-specific models for use in a VR surgical rehearsal platform. Subjects then rehearsed a virtual mastoidectomy on data sets derived from their specimens. Surgical confidence surveys were administered again. Subjects then dissected assigned cadaver specimens, which were blindly graded with a modified Welling scale. A final survey assessed the perceived utility of rehearsal on dissection performance. Results Of 16 subjects, 14 (87.5%) reported a significant increase in overall confidence after conducting an anatomy-specific VR rehearsal. A significant correlation existed between perceived utility of rehearsal and confidence improvement. The effect of rehearsal on confidence was dependent on trainee experience and the inherent difficulty of the surgical subtask. Postrehearsal confidence correlated strongly with graded dissection performance. Subjects rated anatomy-specific rehearsal as having a moderate to high contribution to their dissection performance. Conclusion Anatomy-specific virtual rehearsal improves surgeon confidence in performing mastoid dissection, dependent on surgeon experience and task difficulty. The subjective confidence gained through rehearsal correlates positively with subsequent

    Much discussion in the area of radioactive waste management has centered on the topic of siting waste facilities in the face of public opposition. Waste managers frequently believe that the public perceives risks associated with radioactive waste as much higher than objective risk. Previous research on this topic confirms that waste managers and the public view the risks differently. The scientific literature in this area has been focused on factors that shape risk perception such as how risk perception varies by group and associations among different types of perceived risk. Research in the area of natural hazards and emergency response has focused on how the public obtains information and how that information is interpreted. In addition, much attention has been given to public involvement and public information programs. Critical to each of these research areas is the role of perception of how informed an individual is on a given risk versus how the individual rates a given risk. This paper seeks to do three things: Look at perception of health risk of radioactive waste in the context of other things related to nuclear technology and radioactivity; Investigate the relationship between perceived knowledge and perceived risk; and Determine social and psychological consequences of perceived risk

    Quality improvement (QI) requires measurement, but medical schools rarely provide opportunities for students to measure their patient outcomes. The authors tested the feasibility and perceived impact of a quality metric report card as part of an Education-Centered Medical Home longitudinal curriculum. Student teams were embedded into faculty practices and assigned a panel of patients to follow longitudinally. Students performed retrospective chart reviews and reported deidentified data on 30 nationally endorsed QI metrics for their assigned patients. Scorecards were created for each clinic team. Students completed pre/post surveys on self-perceived QI skills. A total of 405 of their patients' charts were abstracted by 149 students (76% response rate; mean 2.7 charts/student). Median abstraction time was 21.8 (range: 13.1-37.1) minutes. Abstracted data confirmed that the students had successfully recruited a "high-risk" patient panel. Initial performance on abstracted quality measures ranged from 100% adherence on the use of beta-blockers in postmyocardial infarction patients to 24% on documentation of dilated diabetic eye exams. After the chart abstraction assignment, grand rounds, and background readings, student self-assessment of their perceived QI skills significantly increased for all metrics, though it remained low. Creation of an actionable health care quality report card as part of an ambulatory longitudinal experience is feasible, and it improves student perception of QI skills. Future research will aim to use statistical process control methods to track health care quality prospectively as our students use their scorecards to drive clinic-level improvement efforts.

    This paper describes a program of research designed to assess the potential impacts of a high-level nuclear waste repository at Yucca Mountain, Nevada, upon tourism, retirement and job-related migration, and business development in Las Vegas and the state. Adverse economic impacts may be expected to result from two related social processes. One has to do with perceptions of risk and socially amplified reactions to ''unfortunate events'' associated with the repository (major and minor accidents, discoveries of radiation releases, evidence of mismanagement, attempts to sabotage or disrupt the facility, etc.). The second process that may trigger significant adverse impacts is that of stigmatization. The conceptual underpinnings of risk perception, social amplification, and stigmatization are discussed in this paper and empirical data are presented to demonstrate how nuclear images associated with Las Vegas and the State of Nevada might trigger adverse effects on tourism, migration, and business development

    There is increasing acceptance that children are not unaware of when they are targets of discrimination. However, discrimination as a consequence of socio-economic disadvantage remains understudied. The aim of this study was to examine the impact of perceived discrimination on well-being, perceptions of safety and school integration amongst children growing up within socio-economically disadvantaged communities in Limerick, Ireland. Mediation analysis was used to explore these relationships and to examine the potential role of parental support and community identity in boys and girls in the 6th to 9th year of compulsory education (N = 199). Results indicate perceived discrimination contributed to negative outcomes in terms of school integration, perceptions of safety and levels of well-being. Age and gender differences were observed which disadvantaged boys and younger children. All negative outcomes were buffered by parental support. Community identity also protected young people in terms of feelings of school integration and risk but not in terms of psychological well-being. Findings are discussed in terms of the different role of family and community supports for children negotiating negative social representations of their community. © 2015 The British Psychological Society.

    The use of standardized patients is not very common in psychiatric nursing education and there has been no study conducted in Turkey. This study evaluated the impact of using standardized patients in psychiatric cases on the levels of motivation and perceived learning of the nursing students. This manuscript addressed the quantitative aspect of a doctoral thesis study in which both quantitative and qualitative methods were used. A pre-test and post-test were employed in the quantitative analysis in a randomized and controlled study design. The motivation scores, and interim and post-test scores for perceived learning were higher in the experimental group compared to pre-test scores and the scores of the control group. The students in the experimental group reported that they felt more competent about practical training in clinical psychiatry, as well as in performing interviews with patients having mental problems, and reported less anxiety about performing an interview when compared to students in the control group. It is considered that the inclusion of standardized patient methodology in the nursing education curriculum in order to improve the knowledge level and skills of students would be beneficial in the training of mental health nurses.

    Cardiologists need to decide which treatments are appropriate for seriously ill patients and whether they align with patient goals. Reconciling medical options with patients' wishes requires skilled communication. Although there is evidence that communication is teachable, few cardiologists receive formal training. To demonstrate that providing communication skills training to cardiologists is feasible and improves their perceived preparedness (PP) for leading difficult conversations. CardioTalk is a workshop to improve communication through short didactic sessions followed by interactions with standardized patients. Competencies include giving bad news, defining goals of care, responding to emotion, supporting religious beliefs, and withdrawing therapies. Settings/Subjects: First year cardiology fellows, heart failure fellows, and cardiac intensive care unit attendings. Surveys evaluated the curriculum's efficacy and learners' PP before and after the workshop. Eight cardiology attendings and 20 cardiology fellows participated. Eighty-nine percent reported having any prior education in communication. Fellows reported more prior education than attendings (100% vs. 62.5%, p = 0.017). Level of PP improved in all competencies for all learners. Ninety-six percent of respondents would recommend the training to peers. All attendings felt that it should be required for cardiologists in the cardiac intensive care unit and reported improved preparedness to teach communication to learners. All learners improved in levels of PP in communication competencies. CardioTalk is the first described training program that prepares cardiologists for the challenges they face when having conversations with seriously ill patients.

    The purpose of this study is to evaluate an educational programme, 'Diabetes Connect: Connecting Professions', which was developed to enhance communication across primary care networks, to support best practice in clinical interventions and progress multidisciplinary team work to benefit patients in diabetes care. A total of 26 workshops were successfully delivered for 309 primary care professionals across the state of Queensland in Australia from November 2011. It consists of two separate, but complementary training elements: a series of online clinical education training modules and state-wide interprofessional learning workshops developed to enhance professional competencies. The evaluation design included completion of online surveys by the participants at two time points: first upon registering for the online modules or workshops; second, one week after attending a workshop. The survey included questions to evaluate the change in role performance measures. Overall, significant increases in participants' current knowledge, perceived ability to adopt this knowledge at work and willingness to change professional behaviour in the short term were observed. The study suggests that for maximum benefit both, workshop and online training, should be combined and made available widely. Future programmes should use a randomised trial design to test the delivery model.

    Parental racial socialization is a parenting tool used to prepare African American adolescents for managing racial stressors. While it is known that parents' racial discrimination experiences affect the racial socialization messages they provide, little is known about the influence of factors that promote supportive and communal parenting, such as perceived neighborhood cohesion. In cohesive neighborhoods, neighbors may help parents address racial discrimination by monitoring youth and conveying racial socialization messages; additionally, the effect of neighborhood cohesion on parents' racial socialization may differ for boys and girls because parents socialize adolescents about race differently based on expected encounters with racial discrimination. Therefore, the current study examines how parents' perception of neighborhood cohesion and adolescents' gender moderate associations between parents' racial discrimination experiences and the racial socialization messages they deliver to their adolescents. Participants were a community sample of 608 African American adolescents (54 % girls; mean age = 15.5) and their primary caregivers (86 % biological mothers; mean age = 42.0). Structural equation modeling indicated that parental racial discrimination was associated with more promotion of mistrust messages for boys and girls in communities with low neighborhood cohesion. In addition, parental racial discrimination was associated with more cultural socialization messages about racial pride and history for boys in neighborhoods with low neighborhood cohesion. The findings suggest that parents' racial socialization messages are influenced by their own racial discrimination experiences and the cohesiveness of the neighborhood; furthermore, the content of parental messages delivered varies based on adolescents' gender.

    Full Text Available Local residents play an important role in the process of sustainable development in tourism. Resident support for tourism development contributes to the health of tourism industry and successful community development. Therefore, it is in the best interest of local residents, the tourism industry, and tourists, that residents have a positive outlook on and positive experiences with tourism development. In order to understand resident support for tourism development from tourism impacts and community quality of life perspective within the rural communities of Orange County, Indiana, USA, this study has examined a proposed structural model which incorporates eight latent variables: (a six types of positive and negative tourism impacts serve as exogenous latent variables; (b tourism-related community quality of life (TCQOL is proposed as the mediating variable; and (c resident support for tourism development is the ultimate dependent variable. The results show that both sociocultural and environmental benefits contribute to the host community’s living experience. Economic and sociocultural benefits, negative sociocultural and environmental impacts, and TCQOL influence resident support for tourism development. This study identified specific tourism impacts that affect TCQOL and resident support for local tourism development. This study affirms that community quality of life (QOL serves an effective predictor of support for tourism development.

    This study investigates the potential impacts of the proposed nuclear waste repository at Yucca Mountain, Nevada, upon tourism, retirement and job-related migration, and business development in Las Vegas and the state. Adverse impacts may be expected to result from perceptions of risk, stigmatization, and socially amplified reactions to 'unfortunate events' associated with the repository (major and minor accidents, discoveries of radiation releases, evidence of mismanagement, attempts to sabotage or disrupt the facility, etc.). The conceptual underpinnings of risk perception, stigmatization, and social amplification are discussed and empirical data are presented to demonstrate how nuclear images associated with Las Vegas and the State of Nevada might trigger adverse economic effects. The possibility that intense negative imagery associated with the repository may cause significant harm to Nevada's economy can no longer be ignored by serious attempts to assess the risks and impacts of this unique facility. The behavioral processes described here appear relevant as well to the social impact assessment of any proposed facility that produces, uses, transports, or disposes of hazardous materials

    2017-08-01

    The current research examines the impact of Deepika Padukone's (one of the most popular Bollywood celebrities) public announcement of struggle with depression on people's perceived efficacy and intentions to seek help for mental healthcare. A survey conducted with 206 participants from India, the country with the highest depression rates in the world, revealed that parasocial interaction with the celebrity mediated the effect of exposure on intentions and efficacy perceptions regarding seeking mental healthcare. Our study expands the research on celebrity influence on health conditions in an international realm and in a mental health context. The findings have immense practical implications and may raise awareness about mental health in India given the popularity and reach of Bollywood among audiences in India and beyond, the level of stigmatization attached to mental health issues in India, and the lack of available resources for care. Theoretically, the study explores processes and effects of involvement with a celebrity and discusses potential implications for the behaviors related to health.

    Clear and complete communication between health care providers is a prerequisite for safe patient management and is a major priority of the Joint Commission's 2008 National Patient Safety Goals. The goal of this study was to describe nurses' perceptions of nurse-physician communication in the long-term care (LTC) setting. Mixed-method study including a self-administered questionnaire and qualitative semistructured telephone interviews of licensed nurses from 26 LTC facilities in Connecticut. The questionnaire measured perceived openness to communication, mutual understanding, language comprehension, frustration, professional respect, nurse preparedness, time burden, and logistical barriers. Qualitative interviews focused on identifying barriers to effective nurse-physician communication that may not have previously been considered and eliciting nurses' recommendations for overcoming those barriers. Three hundred seventy-five nurses completed the questionnaire, and 21 nurses completed qualitative interviews. Nurses identified several barriers to effective nurse-physician communication: lack of physician openness to communication, logistic challenges, lack of professionalism, and language barriers. Feeling hurried by the physician was the most frequent barrier (28%), followed by finding a quiet place to call (25%), and difficulty reaching the physician (21%). In qualitative interviews, there was consensus that nurses needed to be brief and prepared with relevant clinical information when communicating with physicians and that physicians needed to be more open to listening. A combination of nurse and physician behaviors contributes to ineffective communication in the LTC setting. These findings have important implications for patient safety and support the development of structured communication interventions to improve quality of nurse-physician communication.

    The impact of vertigo and dizziness on healthy ageing, and especially on participation, is not fully understood. The objective of this study was to investigate the association of vertigo and dizziness with self-perceived participation and autonomy in older non-institutionalised individuals, adjusted for the presence of other health conditions. Specifically, we wanted to investigate the different effects of vertigo and dizziness on specific components of participation, i.e. restrictions in indoor and outdoor autonomy, family role, social life and relationships, and work and education. Data originate from the second wave of the German KORA-Age cohort study collected in 2012. Participation and autonomy was investigated with the Impact on Participation and Autonomy Questionnaire. We used robust regression to analyse the association of vertigo and dizziness with self-perceived participation and autonomy adjusted for covariates. A total of 822 participants (49.6% female) had a mean age of 78.1 years (SD 6.39). Participation and autonomy were significantly lower in participants with vertigo and dizziness across all domains. Adjusted for age, sex, and chronic conditions, vertigo and dizziness were significantly associated with participation restrictions in all domains except social life and relationships. The results of our study indicate that vertigo and dizziness contribute to restrictions in participation and autonomy in individuals of older age. Recognising vertigo and dizziness as independent contributors to loss of autonomy and decreased chances for independent living may create new options for patient care and population health, such as the designing of complex interventions to maintain participation and autonomy.

    Interpersonal factors play a major role in causing and maintaining depression. This study sought to investigate how patients' self-perceived interpersonal problems and impact messages as perceived by significant others are interrelated, change over therapy, and differentially predict process and outcome in psychotherapy of depression. For the present study, we used data from 144 outpatients suffering from major depression that were treated within a psychotherapy study. Interpersonal variables were assessed pre- and posttherapy with the self-report Inventory of Interpersonal Problems-Circumplex Scale (IIP-32; Thomas, Brähler, & Strauss, 2011) and with the informant-based Impact Message Inventory (Caspar, Berger, Fingerle, & Werner, 2016). Patients' levels on the dimensions of Agency and Communion were calculated from both measures; their levels on Interpersonal Distress were measured with the IIP. Depressive and general symptomatology was assessed at pre-, post-, and at 3-month follow-up; patient-reported process measures were assessed during therapy. The Agency scores of IIP and IMI correlated moderately, but the Communion scores did not. IIP Communion was positively associated with the quality of the early therapeutic alliance and with the average level of cognitive-emotional processing during therapy. Whereas IIP Communion and IMI Agency increased over therapy, IIP Distress decreased. A pre-post-decrease in IIP Distress was positively associated with pre-postsymptomatic change over and above the other interpersonal variables, but pre-post-increase in IMI Agency was positively associated with symptomatic improvement from post- to 3-month follow-up. These findings suggest that significant others seem to provide important additional information about the patients' interpersonal style. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    This study aimed to investigate the perceptions of primary care workers about the impacts of the national essential medicines policy (NEMP). A cross-sectional questionnaire survey was undertaken in 42 urban community health centres randomly selected from four provinces in China. 791 primary care workers rated the impacts of the NEMP on a 5-point Likert scale. An average score for the impacts of the NEMP on four aspects (the practice of health workers, interactions of patients with health workers, operations of health centres and provision of medicines) was calculated, each ranging from 0 to 100. A higher score indicates a more positive rating. Linear regression models were established to determine the sociodemographic characteristics (region, age, gender, profession, training, income) that were associated with the ratings. The respondents gave an average rating score of 65.61±11.76, 63.17±13.62, 66.35±13.02 and 67.26±11.60 for the impacts of the NEMP on health workers, patients, health centres and provision of medicines, respectively. Respondents from the central region rated the NEMP higher than those from the eastern and western regions. The pharmacists (β=5.457~7.558, pimpacts (as perceived by the health workers) on health services delivery in primary care settings. However, the impacts of the NEMP vary by region, professional practice and the income level of health workers.

    This preliminary study investigated both the impact of oily skin on quality of life (QoL) and the agreement between subjective oily skin self-assessment and objective skin surface sebum measurement in young to middle-aged Chinese women in Beijing. A 18-item Chinese version of the Oily Skin Self-Image Questionnaire (OSSIQ) was used to assess the impact of oily skin on QoL in 300 healthy female subjects (age groups: 20-25; 26-30; 31-35,). The subjects were divided equally into the oily skin group and the non-oily skin group based on their self-perception of skin oiliness. The level of skin surface lipids (SSL) was measured on the middle of the forehead, and both cheeks using the Sebumeter(®). In order to assess the agreement between self-perceived skin oiliness and measured SSL, we tentatively used the SSL median value as a dividing point to regroup all subjects. The results indicate that the Chinese version of the OSSIQ distinguished the oily skin group from the non-oily skin group. Subjects in the oily skin group had significant higher emotional status score and behavior score when compared with subjects in the non-oily skin group. Subjects in the oily skin group had higher SSL when compared with subjects in the non-oily skin group, especially in younger age groups. The agreement between self-perceived skin oiliness and measured SSL was moderately strong in younger age groups, and declined with age. These results strongly suggest that having oily skin can cause a significant negative impact on QoL among Chinese women. The Chinese version of the OSSIQ is a reliable and valid tool for assessing the impact of oily skin on QoL. The accuracy of oily skin self-assessment declines with age. © 2013 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    Much research focuses on organizational culture and its impact on customer orientation or emotional states and their impact on job satisfaction and well-being. This study aims to combine the complex roles of nurses' emotion states and job satisfaction in a model that identifies the effects of standards for service delivery (organizational culture), supervisor and co-worker support and the development of customer orientation. A previous study examined the relationships between nurses' personal resources, job satisfaction and customer orientation. This study examines how these variables relate to organizational standards and social support. A cross-sectional survey using a self-completion questionnaire with validated, existing scales to measure standards for service delivery, supervisor and co-worker support, job satisfaction, empathic concern, emotional exhaustion and customer orientation. Nurses (159) completed the questionnaire in 2010. The data were analysed using WarpPLS, a structural equation modelling software package. The results indicate that the final model fits the data well and explains 84% of the variance in customer orientation. The findings show the importance of standard for service delivery (organizational culture), supervisor and co-worker support on customer orientation. Nurses' personal resources interact with these, particularly supervisor and co-worker support, to develop staff job satisfaction and empathy. The need for support mechanisms in stressful times is discussed. We propose that training in compassion and empathy would help leaders to model desirable attributes that contribute towards customer orientation. © 2015 John Wiley & Sons Ltd.

    This paper presents the results of a study conducted in a pastoral community in Kenya using participatory appraisal approaches. The objective of the study was to assess the socio-economic impact of camel trypanosomosis (surra) according to the perceptions of the pastoralists. Four livestock grazing units were conveniently selected and in each of them, three groups of key informants comprising five to eight persons were selected for the participatory exercises. Five camel diseases were listed in order of importance according to their severity and frequency of occurrence including trypanosomosis, mange, non-specific diarrhoea, tick infestations and haemorrhagic septicaemia. The losses listed as incurred due to the five diseases were: losses in milk, meat, blood, fats and hides, dowry payments, and depreciation in sale of animals, losses due to infertility and abortions, and losses due to the cost of treatment. There was good agreement (P impact. There is a need for veterinary and policy decision-makers to focus more attention on the control of surra in this arid and semi-arid area of Kenya.

  6. Work-family conflict in context: the impact of structural and perceived neighborhood disadvantage on work-family conflict.

    2015-03-01

    Despite increasing levels of work-family conflict (WFC) among North Americans, few scholars examine the broader contexts in which these conflicts occur. I address this gap by examining how the neighborhood of residence impacts WFC, with a focus on social inequality and disadvantage across neighborhoods. I hypothesize that neighborhood disadvantage may impact WFC directly-by introducing ambient stressors that inhibit individuals from successfully balancing competing domain demands, and indirectly-by undermining the psychological resources that would combat the harmful effects of disadvantaged contexts. Using individual and census-level data from Canada, I consider both objective and subjective measures of neighborhood disadvantage and find that, overall, individuals in more disadvantaged neighborhoods are worse off because these contexts increase WFC, while reducing the psychological resources that would otherwise buffer these deleterious effects. However, some of these associations vary by gender. I discuss the broader implications of these findings for neighborhood effects and WFC research. Copyright © 2014 Elsevier Inc.

    This study aimed to evaluate a new service role in mental health services, namely, the senior dual disability coordinator role (SDDC) for its impact on the perceived self-efficacy of mental health clinicians in managing clients with dual disability (mental illness and acquired brain injury and/or intellectual disability) and their job satisfaction. Mental health clinicians from a health service district in Queensland, Australia who contacted the SDDC for clinical consultation and liaison between July 2011 and July 2013 were asked to complete a questionnaire assessing perceived self-efficacy in working with clients with dual disability as well as their job satisfaction, prior to (T1) and following (T2) their contact with the SDDC. Twenty-five clinicians completed and returned pre- and post-measure questionnaires. Self-reported knowledge of dual disability, clinical skills in dual disability, service knowledge in dual disability as well as perceived self-efficacy, and job satisfaction increased significantly from T1 to T2. There were no significant differences across professional discipline or years of service. The delivery of a clinical consultation liaison service as part of the role of SDDC may assist mental health clinicians with self-efficacy and job satisfaction, regardless of the number of years they have worked in the service or their professional discipline. Mental health clinicians with improved self-efficacy for working with clients with dual disability may be more likely to consider the client suitable for services through mental health and follow-up with treatment and linking the client with other identified suitable services. Implications for Rehabilitation Dual disability (mental illness and acquired brain injury and/or intellectual disability) presents specific challenges for mental health services Specific strategies are needed to build capacity among mental health practitioners in order to meet the needs of people with dual disability and provide

    Full Text Available INTRODUCTION: Doctors are increasingly involved in the management of chronic disease and counsel patients about their lifestyle behaviours, including nutrition, to improve their health outcomes. AIM: This study aimed to assess the impact of a medical undergraduate course containing nutrition content on medical students’ self-perceived nutrition intake and self-efficacy to improve their health behaviours and counselling practices. METHODS: A total of 239 medical students enrolled in a 12-week nutrition-related course at The University of Auckland were invited to complete an anonymous questionnaire before and after the course. The questionnaire was adapted from a previous evaluation of a preventive medicine and nutrition course at Harvard Medical School. RESULTS: Sixty-one medical students completed both pre- and post-course questionnaires (25.5%. At baseline, medical students described their eating habits to be more healthy than non-medical students (p=0.0261. Post-course, medical students reported a higher frequency of wholegrain food intake (p=0.0229. Medical students also reported being less comfortable making nutrition recommendations to family and friends post-course (p=0.008. Most medical students (63.9% perceived increased awareness of their own dietary choices, and some (15.3% reported an increased likelihood to counsel patients on lifestyle behaviour post-course. DISCUSSION: Students can increase awareness of their own nutrition behaviour after undertaking a course that includes nutrition in the initial phase of their medical degree. Further investigation of how medical students’ confidence to provide nutrition advice evolves throughout their training and in future practice is required.

    Purpose: Complex intensity modulated arc therapy tends to spread low dose to normal tissue(NT)regions to obtain improved target conformity and homogeneity and OAR sparing.This work evaluates the trade-offs between PTV homogeneity and reduction of the maximum dose(Dmax)spread to NT while planning of IMRT,VMAT and Tomotherapy. Methods: Ten prostate patients,previously planned with step-and-shoot IMRT,were selected.To fairly evaluate how PTV homogeneity was affected by NT Dmax constraints,original IMRT DVH objectives for PTV and OARs(femoral heads,and rectal and bladder wall)applied to 2 VMAT plans in Pinnacle(V9.0), and Tomotherapy(V4.2).The only constraint difference was the NT which was defined as body contours excluding targets,OARs and dose rings.NT Dmax constraint for 1st VMAT was set to the prescription dose(Dp).For 2nd VMAT(VMAT-NT)and Tomotherapy,it was set to the Dmax achieved in IMRT(~70-80% of Dp).All NT constraints were set to the lowest priority.Three common homogeneity indices(HI),RTOG-HI=Dmax/Dp,moderated-HI=D95%/D5% and complex-HI=(D2%-D98%)/Dp*100 were calculated. Results: All modalities with similar dosimetric endpoints for PTV and OARs.The complex-HI shows the most variability of indices,with average values of 5.9,4.9,9.3 and 6.1 for IMRT,VMAT,VMAT-NT and Tomotherapy,respectively.VMAT provided the best PTV homogeneity without compromising any OAR/NT sparing.Both VMAT-NT and Tomotherapy,planned with more restrictive NT constraints,showed reduced homogeneity,with VMAT-NT showing the worst homogeneity(P<0.0001)for all HI.Tomotherapy gave the lowest NT Dmax,with slightly decreased homogeneity compared to VMAT. Finally, there was no significant difference in NT Dmax or Dmean between VMAT and VMAT-NT. Conclusion: PTV HI is highly dependent on permitted NT constraints. Results demonstrated that VMAT-NT with more restrictive NT constraints does not reduce Dmax NT,but significantly receives higher Dmax and worse target homogeneity.Therefore, it is critical

    2015-11-01

    Full Text Available The present study explored whether the optic flow deficit in Alzheimer’s disease (AD reported in the literature transfers to different types of optic flow, in particular, one that specifies collision impacts with upcoming surfaces, with a special focus on the effect of retinal eccentricity. Displays simulated observer movement over a ground plane toward obstacles lying in the observer’s path. Optical expansion was modulated by varying tau-dot. The visual field was masked either centrally (peripheral vision or peripherally (central vision using masks ranging from 10° to 30° in diameter in steps of 10°. Participants were asked to indicate whether their approach would result in collision or no collision with the obstacles. Results showed that AD patients’ sensitivity to tau-dot was severely compromised, not only for central vision but also for peripheral vision, compared to age- and education-matched elderly controls. The results demonstrated that AD patients’ optic flow deficit is not limited to radial optic flow but includes also the optical pattern engendered by tau-dot. Further deterioration in the capacity to extract tau-dot to determine potential collisions in conjunction with the inability to extract heading information from radial optic flow would exacerbate AD patients’ difficulties in navigation and visuospatial orientation.

    To determine the extent of restrictions to medical student documentation in patients' records and the opinions of medical education leaders about such restrictions' impact on medical student education and patient care. Education deans (n = 126) of medical schools in the United States and Canada were surveyed to determine policies regarding placement of medical student notes in the patient record, the value of medical students' documentation in the medical record, and the use of electronic medical records (EMRs) for patient notes. The instrument was a 23-item anonymous Web survey. Seventy-nine deans responded. Over 90% believed student notes belong in medical records, but only 42% had a policy regarding this. Ninety-three percent indicated that without student notes, student education would be negatively affected. Fewer (56%) indicated that patient care would be negatively affected. Most thought limiting students' notes would negatively affect several other issues: feeling a part of the team (96%), preparation for internship (95%), and students' sense of involvement (94%). Half (52%) reported that fourth-year students could place notes in paper charts at "all" affiliated hospitals, and 6% reported that fourth-year students could do so at "no" hospitals. Although students' ability to enter notes in patients' records is believed to be important for student education, only about half of all hospitals allow all students' notes in the EMR. Policies regarding placement of student notes should be implemented to ensure students' competency in note writing and their value as members of the patient care team.

    Whereas the psychosocial benefits of orthognathic treatment for the individual patient are established, there is little data relating to social perceptions in relation to changes in facial appearance as a result of combined orthodontic and orthognathic treatment. This study aimed to investigate the social impact of combined orthodontic-orthognathic surgical correction for class III malocclusion in Caucasian subjects. This cross-sectional study compared perceptions of facial appearance prior to and after orthognathic correction of class III malocclusion. Eighty undergraduate students were shown photographs of four Caucasian subjects (2 male and 2 female) pre- and post-orthognathic class III correction. Observers were asked to rate these subjects in relation to four different outcomes: (i) social competence (SC); (ii) intellectual ability (IA); (iii) psychological adjustment (PA); (iv) attractiveness. A mixed-model analysis of variance (ANOVA) was calculated to determine the effect of each variable. Statistically significant differences were found in ratings of the same face before and after treatment. After treatment, faces were rated as more psychologically adjusted, more sociable, more likely to be successful and more attractive; with the mean psychological adjustment rating being associated with the most change (before treatment=8.06 [SD 2.30]; after treatment=6.64 [SD 2.03], t=2.04, pclass III malocclusion in Caucasians, individuals are rated by young adults as being better adjusted both psychologically and socially, more likely to be successful and more attractive.

    Full Text Available Abstract Background Healthcare professionals have shown concern about performing mouth-to-mouth ventilation due to the risks to themselves with the procedure. However, little is known about healthcare professionals' fears and attitudes to start CPR and the impact of training. Objective To examine whether there were any changes in the attitudes among healthcare professionals to performing CPR from before to after training. Methods Healthcare professionals from two Swedish hospitals were asked to answer a questionnaire before and after training. The questions were relating to physical and mental discomfort and attitudes to CPR. Statistical analysis used was generalized McNemar's test. Results Overall, there was significant improvement in 10 of 11 items, reflecting various aspects of attitudes to CPR. All groups of health care professionals (physicians, nurses, assistant nurses, and "others" = physiotherapists, occupational therapists, social welfare officers, psychologists, biomedical analysts felt more secure in CPR knowledge after education. In other aspects, such as anxiety prior to a possible cardiac arrest, only nurses and assistant nurses improved. The concern about being infected, when performing mouth to mouth ventilation, was reduced with the most marked reduction in physicians (75%; P Conclusion In this hospital-based setting, we found a positive outcome of education and training in CPR concerning healthcare professionals' attitudes to perform CPR. They felt more secure in their knowledge of cardiopulmonary resuscitation. In some aspects of attitudes to resuscitation nurses and assistant nurses appeared to be the groups that were most markedly influenced. The concern of being infected by a disease was low.

    The "all-natural" label is used extensively in the United States. At many point-of-purchase locations, employed servers provide food samples and call out specific label information to influence consumers' purchase decisions. Despite these ubiquitous practices, it is unclear what information is conveyed to consumers by the all-natural label or how it impacts judgments of perceived food quality, nutritional content, and acceptance. We used a novel approach incorporating immersive technology to simulate a virtual in-store sampling scenario where consumers were asked by a server to evaluate identical products with only one being labeled all-natural. Another condition evaluated the impact of the in-store server additionally emphasizing the all-natural status of one sample. Results indicated the all-natural label significantly improved consumer's perception of product quality and nutritional content, but not liking or willingness to pay, when compared to the regular sample. With the simple emphasis of the all-natural claim by the in-store server, these differences in quality and nutritional content became even more pronounced, and willingness to pay increased significantly by an average of 8%. These results indicate that in a virtual setting consistent with making food purchases, an all-natural front-of-pack label improves consumer perceptions of product quality and nutritional content. In addition, information conveyed to consumers by employed servers has a further, substantial impact on these variables suggesting that consumers are highly susceptible to social influence at the point of purchase. © 2017 Institute of Food Technologists®.

    Utah is rich in oil shale and oil sands resources. Chief among the challenges facing prospective unconventional fuel developers is the ability to access these resources. Access is heavily dependent upon land ownership and applicable management requirements. Understanding constraints on resource access and the prospect of consolidating resource holdings across a fragmented management landscape is critical to understanding the role Utah’s unconventional fuel resources may play in our nation’s energy policy. This Topical Report explains the historic roots of the “crazy quilt” of western land ownership, how current controversies over management of federal public land with wilderness character could impact access to unconventional fuels resources, and how land exchanges could improve management efficiency. Upon admission to the Union, the State of Utah received the right to title to more than one-ninth of all land within the newly formed state. This land is held in trust to support public schools and institutions, and is managed to generate revenue for trust beneficiaries. State trust lands are scattered across the state in mostly discontinuous 640-acre parcels, many of which are surrounded by federal land and too small to develop on their own. Where state trust lands are developable but surrounded by federal land, federal land management objectives can complicate state trust land development. The difficulty generating revenue from state trust lands can frustrate state and local government officials as well as citizens advocating for economic development. Likewise, the prospect of industrial development of inholdings within prized conservation landscapes creates management challenges for federal agencies. One major tension involves whether certain federal public lands possess wilderness character, and if so, whether management of those lands should emphasize wilderness values over other uses.

    2009-01-01

    Recently we have proposed the use of Tikhonov regularization with temporal smoothness constraints to estimate the BOLD fMRI hemodynamic response function (HRF). The temporal smoothness constraint was imposed on the estimates by using second derivative information while the regularization parameter was selected based on the generalized cross-validation function (GCV). Using one-dimensional simulations, we previously found this method to produce reliable estimates of the HRF time course, especially its time to peak (TTP), being at the same time fast and robust to over-sampling in the HRF estimation. Here, we extend the method to include simultaneous temporal and spatial smoothness constraints. This method does not need Gaussian smoothing as a pre-processing step as usually done in fMRI data analysis. We carried out two-dimensional simulations to compare the two methods: Tikhonov regularization with temporal (Tik-GCV-T) and spatio-temporal (Tik-GCV-ST) smoothness constraints on the estimated HRF. We focus our attention on quantifying the influence of the Gaussian data smoothing and the presence of edges on the performance of these techniques. Our results suggest that the spatial smoothing introduced by regularization is less severe than that produced by Gaussian smoothing. This allows more accurate estimates of the response amplitudes while producing similar estimates of the TTP. We illustrate these ideas using real data. (note)

    Gestational Trophoblastic Disease (GTD) comprises a group of disorders that derive from the placenta. Even if full recovery is generally expected, women diagnosed with GTD have to confront: the loss of a pregnancy, a potentially life-threatening diagnosis and delays in future pregnancies. The aim of the study is to evaluate the psychological impact of GTD, focusing on perceived fertility, depression and anxiety. 37 patients treated for GTD at San Raffaele Hospital, Milan, took part in the study. The STAI-Y (State-Trait Anxiety Inventory), the BDI-SF (Beck Depression Scale-Short Form) and the FPI (Fertility Problem Inventory) were used. Patients were grouped on the basis of presence of children (with or without), age (statistic. Three-way ANOVAs were also carried out considering the same block factors. The study highlights that women suffering from GTN had higher depression scores compared to women suffering from HM. A significant correlation was found between anxiety (state and trait) and depression. Younger women presented higher Global Stress scores on the FPI, especially tied to Need for Parenthood and Relationship Concern subscales. Need for Parenthood mean scores significantly varied between women with and without children too. We can conclude that fertility perception seems to be negatively affected by GTD diagnosis, particularly in younger women and in those without children. Patients should be followed by a multidisciplinary team so as to be supported in the disease's psychological aspects too.

  2. Constraints on the Nature and Distribution of Iridium Host Phases at the Cretaceous-Tertiary Boundary: Implications for Projectile Identity and dispersal on impact

    Among Cretaceous-Tertiary boundary sites worldwide, variations in the concentrations and ratios of elements commonly enriched in meteorites complicate traditional geochemical attempts at impactor identification. Yet they may provide constraints on the physical and chemical processes associated with large-body disruption and dispersal, as well as with diagenesis of projectile components. To this end, we continue our efforts to identify the mineral host-phases of projectile-derived elements, particularly for Ir, and to document their partitioning between crater deposits and ejecta resulting from the Chicxulub basin-forming impact. Building on earlier work, we used INAA to measure Ir concentrations in successively smaller splits of finely powdered impact melt breccia from the Chicxulub Crater in Mexico (sample Y6Nl9-R(b)), and K/T boundary fish clay from Stevns Klint, Denmark (sample FC-1, split from 40 kg of homogenized material intended as an analytical standard). Results for the Chicxulub sample show a heterogeneous Ir distribution and document that at least five discrete Ir-bearing host phases were isolated in subsequent splits, having Ir masses equivalent to pure Ir spheres from about 0.8 to about 3.5 mm in diameter. Three of these are within a sufficiently reduced mass of powder to warrant searching for them using backscattered electron microscopy. In contrast, successively smaller splits of the Stevns Klint fish clay show no statistically significant deviation from the reported value of 32 +/- 2 ng/g Ir, suggesting a uniform Ir host-phase distribution. For the smallest split obtained thus far (100 +/- 40 ng/g Ir), a pure Ir sphere of equivalent Ir mass would be <0.05 min in diameter. (n.b. Although homogenizing and sieving of FC-1 to <75 min obviously obscured variations in stratigraphic distribution, it is unlikely to have affected the size-frequency distribution of Ir host phases.) We previously identified micrometer-scale Ir host phases by electron

    Chest wall toxicities are recognized complications of stereotactic radiotherapy (SBRT) in non-small cell lung cancer. To minimize toxicity, the Trans-Tasman Radiation Oncology Group (TROG) 09.02 ‘CHISEL’ study protocol excluded patients with tumours within 1cm of the chest wall. The purpose of this study is to evaluate the implication of chest wall proximity constraints on patient eligibility, toxicity and potential accrual. Exclusion zones of 1cm beyond the mediastinum and 2cm beyond the bifurcation of the lobar bronchi were incorporated into the CHISEL credentialing CT dataset. Volumes of lung within which tumours varying from 1cm to 5cm in diameter may occupy and remain eligible for the CHISEL study were calculated. These volumes were compared to a hypothetical model in which the 1cm chest wall proximity restriction was removed. The percentage of lung area in which a tumour mass can occupy and be suitable for CHISEL in the left and right lung were 54% and 60% respectively. Removing the constraint increased the percentage of available lung to 83% and 87% respectively. Considering a 2cm spherical tumour, only 21% and 31% of tumours in the left and right lung would be eligible with the chest wall constraint, whilst 39% and 50% respectively would be eligible without the constraint. The exclusion of tumours less than 1cm to chest wall significantly reduces the proportion of patients eligible for the CHISEL protocol. A review of the literature pertaining to chest wall toxicity after stereotactic radiotherapy supports a change in chest wall exclusion criteria for the CHISEL study.

    Media presentations of e-cigarettes may affect perception of the devices which may influence use. To assess in a cohort of past-year smokers (1) if perceived harm of e-cigarettes relative to cigarettes changed over time, (2) predictors of perceived relative harm, (3) if perceived relative harm predicted subsequent e-cigarette use among never-users. Longitudinal web-based survey of a general population sample of British smokers and ex-smokers, waves in 2012 (n=4553), 2013 and 2014 (44%, 31% response rate, respectively). Changes over time were assessed using Friedman and McNemar tests, n=1204. Perceived relative harm at wave 3 was regressed onto perceived relative harm at waves 1 and 2, while adjusting for socio-demographics and change in smoking and e-cigarette status, n=1204. Wave 2 e-cigarette use among 1588 wave 1 never-users was regressed onto wave 1 socio-demographics, smoking status and perceived relative harm. Perceived relative harm changed (χ(2)=20.67, pe-cigarette use in never-users; this perception declined over time. Clear information on the relative harm of cigarettes and e-cigarettes is needed.

  9. A multicase study of the impact of perceived gender roles on the career decisions of women in science-related careers

    Hren, Stephen Frank

    The purpose of this study was to determine how perceived gender roles developed throughout childhood and early adulthood impacted the career decisions of women in science-related career fields. An additional purpose was to determine if my experiences as I analyzed the data and the propositions discovered in the study would become a transformative agent for me. A multicase framework was utilized so that within and between case analyses could be achieved. Four women who showed early promise in science were chosen as the case study participants. The relationship of gender roles to the career decisions made by the four cases were arbitrated through three areas: (a) supports, which came from parents, immediate family members, spouses, teachers, mentors, and collaborators; (b) opportunities, which were separated into family experiences and opportunities, school and community opportunities, and postsecondary/current opportunities; and (c) postmodern feminism, which was the lens that grounded this study and fit well with the lives of the cases. As seen through a postmodern feminist lens, the cases' social class, their lived experiences tied to their opportunities and supports, and the culture of growing up in a small rural community helped them develop personas for the professions they chose even where those professions did not necessarily follow from the early promise shown for a science-related career. In addition, as related to my transformation as a male researcher, being a male conducting research in a realm most often shared by women, I was able to gain greater empathy and understanding of what it takes for women to be successful in a career and at the same time maintain a fruitful family life.

  11. Perceived overprotection: support gone bad?

    2006-01-01

    This article focuses on the effects of perceived overprotection, a potentially problematic aspect of receiving support, on the ability to adjust to a chronic impairment, specifically, age-related vision loss. Perceived overprotection is an especially critical issue in this population of chronically ill older adults because of the safety issues associated with vision impairment and because perceptions on the part of the older adult that the support providers are overprotective may lead to excess disability. Participants were 584 older men and women with age-related vision impairment who applied for services at a vision rehabilitation agency. Path analysis was used to examine the effects of perceived overprotection on two positive indicators of adjustment: vision-specific adaptation and environmental mastery. Moreover, antecedents of perceived overprotection were examined. Higher levels of perceived overprotection were associated with less optimal adjustment to age-related vision loss, with lower scores on measures of vision-specific adaptation and environmental mastery. Higher levels of functional disability and instrumental support received were associated with higher levels of perceived overprotection. Findings indicate that support providers of older adults with visual impairment as well as vision rehabilitation service providers need to be aware of the detrimental impact of perceived overprotection.

    In patients with chronic obstructive pulmonary disease (COPD), exercise capacity is reduced, resulting over time in physical inactivity and worsened health status. It is unknown whether ventilatory constraints occur during activities of daily life (ADL) in early stages of COPD. The aim of this study was to assess respiratory mechanics during ADL and to study its consequences on dyspnoea, physical activity and health status in early-stage COPD compared with healthy controls. In this cross-sectional study, 39 early-stage COPD patients (mean FEV 1 88±s.d. 12% predicted) and 20 controls performed 3 ADL: climbing stairs, vacuum cleaning and displacing groceries in a cupboard. Respiratory mechanics were measured during ADL. Physical activity was measured with accelerometry. Health status was assessed by the Nijmegen Clinical Screening Instrument. Compared with controls, COPD patients had greater ventilatory inefficiency and higher ventilatory requirements during ADL (P50% of the patients developed dynamic hyperinflation in contrast to 10-35% of the controls. Higher dyspnoea was scored by patients with dynamic hyperinflation. Physical activity was low but comparable between both groups. From the patients, 55-84% experienced mild-to-severe problems in health status compared with 5-25% of the controls. Significant ventilatory constraints already occur in early-stage COPD patients during common ADL and result in increased dyspnoea. Physical activity level is not yet reduced, but many patients already experience limitations in health status. These findings reinforce the importance of early diagnosis of COPD and assessment of more than just spirometry.

  2. Constraint-based reachability

    Full Text Available Iterative imperative programs can be considered as infinite-state systems computing over possibly unbounded domains. Studying reachability in these systems is challenging as it requires to deal with an infinite number of states with standard backward or forward exploration strategies. An approach that we call Constraint-based reachability, is proposed to address reachability problems by exploring program states using a constraint model of the whole program. The keypoint of the approach is to interpret imperative constructions such as conditionals, loops, array and memory manipulations with the fundamental notion of constraint over a computational domain. By combining constraint filtering and abstraction techniques, Constraint-based reachability is able to solve reachability problems which are usually outside the scope of backward or forward exploration strategies. This paper proposes an interpretation of classical filtering consistencies used in Constraint Programming as abstract domain computations, and shows how this approach can be used to produce a constraint solver that efficiently generates solutions for reachability problems that are unsolvable by other approaches.

    Space tourism appears today as a new Eldorado in a relatively near future. Private operators are already proposing services for leisure trips in Low Earth Orbit, and some happy few even tested them. But are these exceptional events really marking the dawn of a new space age ? The constraints associated to the space tourism are severe : - the economical balance of space tourism is tricky; development costs of large manned - the technical definition of such large vehicles is challenging, mainly when considering - the physiological aptitude of passengers will have a major impact on the mission - the orbital environment will also lead to mission constraints on aspects such as radiation, However, these constraints never appear as show-stoppers and have to be dealt with pragmatically: - what are the recommendations one can make for future research in the field of space - which typical roadmap shall one consider to develop realistically this new market ? - what are the synergies with the conventional missions and with the existing infrastructure, - how can a phased development start soon ? The paper proposes hints aiming at improving the credibility of Space Tourism and describes the orientations to follow in order to solve the major hurdles found in such an exciting development.

    Identifying modifiable correlates of good quality of life in adults with autism spectrum disorder is of paramount importance for intervention development as the population of adults with autism spectrum disorder increases. This study sought to examine social support and perceived stress as potential modifiable correlates of quality of life in adults with autism spectrum disorder. We hypothesized that adults with autism spectrum disorder without co-occurring intellectual disabilities ( N = 40; aged 18-44 years) would report lower levels of social support and quality of life than typical community volunteers who were matched for age, sex, and race ( N = 25). We additionally hypothesized that social support would buffer the effect of perceived stress on quality of life in adults with autism spectrum disorder. Results indicated that adults with autism spectrum disorder reported significantly lower levels of social support and quality of life than matched typical community volunteers. In addition, findings showed significant direct effects of social support and perceived stress on quality of life in adults with autism spectrum disorder. Social support did not buffer the effect of perceived stress on quality of life. Interventions that teach adults with autism spectrum disorder skills to help them better manage stress and cultivate supportive social relationships have the potential to improve quality of life.

  12. Momentum constraint relaxation

    Marronetti, Pedro

    2006-01-01

    Full relativistic simulations in three dimensions invariably develop runaway modes that grow exponentially and are accompanied by violations of the Hamiltonian and momentum constraints. Recently, we introduced a numerical method (Hamiltonian relaxation) that greatly reduces the Hamiltonian constraint violation and helps improve the quality of the numerical model. We present here a method that controls the violation of the momentum constraint. The method is based on the addition of a longitudinal component to the traceless extrinsic curvature A ij -tilde, generated by a vector potential w i , as outlined by York. The components of w i are relaxed to solve approximately the momentum constraint equations, slowly pushing the evolution towards the space of solutions of the constraint equations. We test this method with simulations of binary neutron stars in circular orbits and show that it effectively controls the growth of the aforementioned violations. We also show that a full numerical enforcement of the constraints, as opposed to the gentle correction of the momentum relaxation scheme, results in the development of instabilities that stop the runs shortly

  13. Selection of new constraints

    International Nuclear Information System (INIS)

    Sugier, A.

    2003-01-01

    The selected new constraints should be consistent with the scale of concern i.e. be expressed roughly as fractions or multiples of the average annual background. They should take into account risk considerations and include the values of the currents limits, constraints and other action levels. The recommendation is to select four leading values for the new constraints: 500 mSv ( single event or in a decade) as a maximum value, 0.01 mSv/year as a minimum value; and two intermediate values: 20 mSv/year and 0.3 mSv/year. This new set of dose constraints, representing basic minimum standards of protection for the individuals taking into account the specificity of the exposure situations are thus coherent with the current values which can be found in ICRP Publications. A few warning need however to be noticed: There is no more multi sources limit set by ICRP. The coherence between the proposed value of dose constraint (20 mSv/year) and the current occupational dose limit of 20 mSv/year is valid only if the workers are exposed to one single source. When there is more than one source, it will be necessary to apportion. The value of 1000 mSv lifetimes used for relocation can be expressed into annual dose, which gives approximately 10 mSv/year and is coherent with the proposed dose constraint. (N.C.)

    Monetary cutbacks have occurred in the healthcare industry with increasing incidence since the mid-1980s. Attempts at self-preservation through cost-constraint have been instituted by hospitals, Medicare and Medicaid, and private insurance companies. Curtailment of expenditures, as well as reestablishing profit, has taken many forms. These include managed care, mergers, changing profit status, and aggressive competition. The purpose of this study was to evaluate whether directors of nurse anesthesia programs (NAPs) perceived these items as being detrimental to their NAPs. Data were gathered by descriptive survey design by completing a survey tool. Findings identified directors perceived NAPs at moderate to high risk for closure because of the financial constraints hospitals are experiencing as a result of healthcare reimbursement cutbacks. We found it interesting that many directors were either unaware or considered the hospitals' financial burdens as not impacting their NAP. However, directors who had taken courses or seminars with a focus on issues affecting the financing and reimbursement of healthcare institutions perceived significantly greater risk than those who did not. Potential learning opportunities and strategies to ameliorate risk were identified. Additional education may provide the knowledge and insight to find alternatives to risk, develop strategies, and promote more successful and stable nurse anesthesia educational programs.

    Full Text Available Previous quantitative studies suggest that the burden researchers who use English as an additional language perceive when writing research articles (RAs for publication in English (as L2 is 24% greater than the burden they perceive when they write RAs for publication in their L1. It remains unclear precisely which aspects of research article (RA writing in English present these writers with the greatest challenge and just why they perceive this increase in difficulty. A structured questionnaire comprising thirty-seven questions about researchers’ publication experiences in scientific journals in English and in Spanish was designed and sent out to all (n = 8,794 Spanish postdoctoral researchers at one research-only institution and four universities in Spain, yielding responses from 1,717 researchers. Our first results show that the discussion is the section that is perceived as more difficult to write for English-medium journals, across the four broad knowledge areas in a way that cannot be fully explained by their lower level of proficiency in English (as L2. This article proposes the rhetorical transfer hypothesis as a possible explanation for their additional difficulty. Our results also reveal that their increased perceived difficulty writing RA discussions in English (as L2 does not decrease noticeably until Spanish researchers report high or very high levels of proficiency in English (as L2 for academic or general purposes or have published on average at least 37 RAs as corresponding author in English-medium journals over the last ten years. Implications for English for Academic Purposes (EAP research and pedagogy are discussed.

  16. Energy constraints and organizational change in US production

    Energy Technology Data Exchange (ETDEWEB)

    1980-12-01

    There is still considerable uncertainty about the way in which energy-supply constraints affect industrial thinking and activity. Yet, this is an important issue in determining the effectiveness of conservation programs and in formulating energy policy. The authors expand on a survey of US business attitudes and responses to energy constraints first published in the September 1979 Energy Policy with the results of further analysis of their survey. In particular, they examine correlations between perceived causes and preferred solutions of energy problems, organizational adjustments to energy constraints in energy-intensive industries, and the ways in which production operations have changed in response to supply problems. 5 references, 5 tables.

    We investigate whether thinking aloud influences perceived time. Thinking aloud is widely used in usability evaluation, yet it is debated whether thinking aloud influences thought and behavior. If thinking aloud is restricted to the verbalization of information to which a person is already attending, there is evidence that thinking aloud does not influence thought and behavior. In an experiment, 16 thinking-aloud participants and 16 control participants solved a code-breaking task 24 times each. Participants estimated task duration. The 24 trials involved two levels of time constraint (timed, untimed) and resulted in two levels of success (solved, unsolved). The ratio of perceived time to clock time was lower for thinking-aloud than control participants. Participants overestimated time by an average of 47% (thinking aloud) and 94% (control). The effect of thinking aloud on time perception also held separately for timed, untimed, solved, and unsolved trials. Thinking aloud (verbalization at Levels 1 and 2) influences perceived time. Possible explanations of this effect include that thinking aloud may require attention, cause a processing shift that overshadows the perception of time, or increase mental workload. For usability evaluation, this study implies that time estimates made while thinking aloud cannot be compared with time estimates made while not thinking aloud, that ratings of systems experienced while thinking aloud may be inaccurate (because the experience of time influences other experiences), and that it may therefore be considered to replace concurrent thinking aloud with retrospective thinking aloud when evaluations involve time estimation.

    Overestimation of the severity of mitral regurgitation (MR) by the proximal isovelocity surface area (PISA) method has been reported. We sought to test whether angle correction (AC) of the constrained flow field is helpful to eliminate overestimation in patients with eccentric MR. In a total of 33 patients with MR due to prolapse or flail mitral valve, both echocardiography and cardiac magnetic resonance image (CMR) were performed to calculate regurgitant volume (RV). In addition to RV by conventional PISA (RV PISA ), convergence angle (α) was measured from 2-dimensional Doppler color flow maps and RV was corrected by multiplying by α/180 (RV AC ). RV measured by CMR (RV CMR ) was used as a gold standard, which was calculated by the difference between total stroke volume measured by planimetry of the short axis slices and aortic stroke volume by phase-contrast image. The correlation between RV CMR and RV by echocardiography was modest [RV CMR vs. RV PISA (r = 0.712, p < 0.001) and RV CMR vs. RV AC (r = 0.766, p < 0.001)]. However, RV PISA showed significant overestimation (RV PISA - RV CMR = 50.6 ± 40.6 mL vs. RV AC - RV CMR = 7.7 ± 23.4 mL, p < 0.001). The overall accuracy of RV PISA for diagnosis of severe MR, defined as RV ≥ 60 mL, was 57.6% (19/33), whereas it increased to 84.8% (28/33) by using RV AC ( p = 0.028). Conventional PISA method tends to provide falsely large RV in patients with eccentric MR and a simple geometric AC of the proximal constraint flow largely eliminates overestimation.

    We examined the cultural influence on perceived body weight and the level of health practices at a national and individual level. At a national level, we found that Japanese women (n = 80) overestimate body weight more than Korean (n = 82) and American (n = 63) women. At an individual level, individuals with interdependent self-construal were more prone to overestimate weight than those with independent self-construal (N = 182; American women). Based on the data, we identify that the relationship is mediated by self-criticism, and, importantly, it is self-criticism rather than perceived overweight that predicts the level of health activities. Health practitioners and campaign designers across cultures are recommended to concentrate on promoting positive body esteem instead of encouraging engagement in corrective health behaviors for weight loss.

  1. Do you get where I'm coming from?: Perceived understanding buffers against the negative impact of conflict on relationship satisfaction.

    Gordon, Amie M; Chen, Serena

    2016-02-01

    Conflict can have damaging effects on relationship health. But is all conflict detrimental? Across 7 studies, we tested the overarching hypothesis that conflict in close relationships is only detrimental when people do not feel their thoughts, feelings, and point of view are understood by their relationship partners. Supporting this, conflict was negatively associated with relationship satisfaction among participants who perceived their romantic partner as less understanding, but not among those who felt more understood by their partners. This was true cross-sectionally (Study 1), experimentally (Studies 2, 3, 6a, and 6b), in daily life (Study 4), and for both members of couples pre- to postconflict conversation in the laboratory (Study 5). The buffering effects of feeling understood could not be explained by people who felt more understood being more understanding themselves, having more general positive perceptions of their partners, fighting about less important or different types of issues, engaging in more pleasant conflict conversations, or being more satisfied with their relationships before the conflict. Perceived understanding was positively associated with conflict resolution, but this did not explain the benefits of feeling understood. Evidence from Studies 6a and 6b suggests that feeling understood during conflict may buffer against reduced relationship satisfaction in part because it strengthens the relationship and signals that one's partner is invested. Overall, these studies suggest that perceived understanding may be a critical buffer against the potentially detrimental effects of relationship conflict. (c) 2016 APA, all rights reserved).

    In this project, we examined the effect of a 4-month intervention with horses on perceived social support, self-esteem and general self-efficacy among Norwegian adolescents aged 12–15 years. The intervention took place at farm-based stables and included work with the horses and riding. A waiting-list crossover design was used and the participants answered questionnaires at three time periods. Study I (N = 49) examined the effect of the intervention compared with the control group. Study II (N = 41) examined the relationship between the same psychological variables and change in mastering skills with horse. The intervention group reported a significant increase in perceived social support compared with the control group. There were no differences in self-esteem and general self-efficacy between the groups. The results from study II showed that a lower level of perceived social support prior to the intervention predicted an increase in mastering skills with the horse during the intervention.

    The meanings attached to the nation can be consequential for group members' attitudes and beliefs. We examined how national identity definition can influence the extent of individuals' homophobia with 159 Lithuanian and 176 Scottish university students who completed a questionnaire which measured their national identification, homophobia, and the extent to which they felt traditional family values were central to their nation's identity. Consistent with nation-wide differences in the significance given to the family, Lithuanian participants perceived family values to be more important for their national identity and expressed higher levels of homophobia than did Scottish participants. Moreover, the relationship between level of national identification and homophobia was stronger in Lithuania than in Scotland. Analyses revealed that the perceived importance of family values helped explain the difference between homophobia levels in Lithuania and Scotland. In both sites we found an indirect effect of national identification on homophobia via the perceived importance of family values, but this effect was significantly stronger for Lithuanian participants. These findings illustrate the ways in which identification with the nation is relevant to attitudes concerning sexuality, and how this varies according to national context. Our work indicates that LGBT rights campaigns should be informed by the knowledge that homophobia may be perpetuated by national valorisation of the family.

    The revision process of the international radiological protection regulations has resulted in the adoption of new concepts, such as practice, intervention, avoidable and restriction of dose (dose constraint). The latter deserving of special mention since it may involve reducing a priori of the dose limits established both for the public and to individuals occupationally exposed, values that can be further reduced, depending on the application of the principle of optimization. This article aims to present, with clarity, from the criteria adopted to define dose constraint values to the public, a methodology to establish the dose constraint values for occupationally exposed individuals, as well as an example of the application of this methodology to the practice of industrial radiography

    Students seeking degrees in healthcare in Ecuador participate in community improvement projects and provide free health services under the supervision of faculty health professionals. The aim of this study is to determine the impact of a community-based intervention delivered by nursing students on health-related quality of life (HRQoL) and perceived social support of a rural population in Ecuador. A quasi-experimental non-equivalent control group design study was conducted in two rural communities in Tumbaco, Ecuador. Families from one rural community were invited to participate in the intervention, receiving 8 weekly home visits from nursing students. Families from a neighboring community were similarly recruited as wait-list controls. One member of each family was consented into the study; the final sample included 43 intervention participants and 55 control participants. HRQoL and perceived social support were assessed before and after the intervention in both groups. The SF-12 was used to measure HRQoL, including eight domain scores and two composite scores, and the Interpersonal Support Evaluation List was used as an indicator of perceived social support. Difference-in-differences (DD) analyses were conducted to mitigate the effects of any baseline differences in the non- equivalent control group design. When compared to the control group, the intervention group realized significant improvements in the physical component summary score of the SF-12 (4.20, p based learning on recipient populations.

    Parents of children and adolescents with diabetes type 1 (DT1) usually experience high stress levels, as they have to cope with multiple demands in their everyday life. Different complex interventions have been implemented, which sometimes have led to opposite results. The purpose of this study was to assess stress levels in parents of children and adolescents with DT1 and to evaluate the effectiveness of a stress management program (progressive muscle relaxation combined with diaphragmatic breathing) in reducing perceived and parenting stress, increasing internal locus of control, promoting healthy lifestyle, and normalizing cortisol levels. Randomized controlled trial. A total of 44 parents were randomly assigned to the intervention group (performing relaxation for eight weeks, n = 19) and control group (n = 25). Pre-post measurements included cortisol levels, lifestyle characteristics, perceived stress, perception of health, and parenting stress. A statistically significant decrease in perceived stress (from 27.21 to 19.00, P = .001), as well as in parenting stress (from 85.79 to 73.68, P = .003), was observed in the intervention group. A statistically significant difference was found in perceived stress between the two groups after the intervention (Dmean = 6.64, P = .010). No significant difference was revealed between or within the groups in cortisol levels. Significant improvement was reported by the subjects of the intervention group in various lifestyle parameters. Relaxation techniques seem to have a positive impact on stress and on various lifestyle factors in parents of children and adolescents with DT1. Future research on long-term benefits of an intervention program comprising of various relaxation schemes is warranted. Copyright © 2014 Elsevier Inc. All rights reserved.

  12. Constraint-based scheduling applying constraint programming to scheduling problems

    Baptiste, Philippe; Nuijten, Wim

    2001-01-01

    Constraint Programming is a problem-solving paradigm that establishes a clear distinction between two pivotal aspects of a problem: (1) a precise definition of the constraints that define the problem to be solved and (2) the algorithms and heuristics enabling the selection of decisions to solve the problem. It is because of these capabilities that Constraint Programming is increasingly being employed as a problem-solving tool to solve scheduling problems. Hence the development of Constraint-Based Scheduling as a field of study. The aim of this book is to provide an overview of the most widely used Constraint-Based Scheduling techniques. Following the principles of Constraint Programming, the book consists of three distinct parts: The first chapter introduces the basic principles of Constraint Programming and provides a model of the constraints that are the most often encountered in scheduling problems. Chapters 2, 3, 4, and 5 are focused on the propagation of resource constraints, which usually are responsibl...

    Full Text Available The research of employability shows tension in the social field of career, where variables such as market value, gender, and personal skills are important. The aim of this study was to identify the predicted weight of market value of type of occupation, sex, and career competences (self-efficacy, pro-activity, and locus of control over objective employability and perceived opportunities for a future career and satisfaction of young professionals. In this study, 294 graduates from 27 different undergraduate degree programs participated, describing their labor situation, satisfaction with career opportunities, and their level in the studied competences. Each type of occupation has a specific market value score, according to national and international criteria. It was possible to identify that the market value of their occupations had significant effects on objective employability (p < .000, f = .48. Also, self-efficacy and locus of control were significant predictors of perceived employability opportunities (p < .000, f = .26. This predictive value of personal variables was different between males (p = .011, f = .82, and females (p < .000, f = .34, and between occupations with low market value (p=.016, f=.45, medium market value (p < .000, f = .34, and high market value (p = .006, f = .21, which allows the development of specific intervention strategies to promote equality in labor opportunities and job placement.

    This paper examines the impacts of wind power generation on the future choice of fuels and technologies in the power sector of Vietnam. The study covers a time frame of 20 yr from 2005 to 2025 and the MARKAL model has been chosen to be adaptable to this specific task. The results of the study show that on a simple cost base, power generated from wind is not yet competitive with that of fossil fuel-based power plants. In order to make wind energy competitive, either carbon tax or an emission reduction target on the system must be imposed. The presence of wind power could affect not only the change in generation mix from coal-based power plants to wind turbines but also an increase in the capacity of other technologies which emit less carbon dioxide. It thus helps reduce fossil fuel requirement and consequently enhances energy security for the country. The study also shows that wind turbine in Vietnam could be a potential CDM project for annex I party countries. (author)

  19. New insights on entrainment and condensation in volcanic plumes: Constraints from independent observations of explosive eruptions and implications for assessing their impacts

    Science.gov (United States)

    Aubry, Thomas J.; Jellinek, A. Mark

    2018-05-01

    The turbulent entrainment of atmosphere and the condensation of water vapor govern the heights of explosive volcanic plumes. These processes thus determine the delivery and the lifetime of volcanic ash and aerosols into the atmosphere. Predictions of plume heights using one-dimensional "integral" models of volcanic plumes, however, suffer from very large uncertainties, related to parameterizations for entrainment and condensation. In particular, the wind entrainment coefficient β, which governs the contribution of crosswinds to turbulent entrainment, is subject to uncertainties of one order of magnitude, leading to relative uncertainties of the order of 50% on plume height. In this study, we use a database of 94 eruptive phases with independent estimates of mass eruption rate and plume height to constrain and evaluate four popular 1D models. We employ re-sampling methods to account for observational uncertainties. We show that plume height predictions are significantly improved when: i) the contribution of water vapor condensation to the plume buoyancy flux is excluded; and ii) the wind entrainment coefficient β is held constant between 0.1 and 0.4. We explore implications of these results for predicting the climate impacts of explosive eruptions and the likelihood that eruptions will form stable umbrella clouds or devastating pyroclastic flows. Last, we discuss the sensitivity of our results to the definition of plume height in the model in light of a recent set of laboratory experiments and draw conclusions for improving future databases of eruption parameters.

  20. Sustainability constraints on UK bioenergy development

    Thornley, Patricia; Upham, Paul; Tomei, Julia

    2009-01-01

    Use of bioenergy as a renewable resource is increasing in many parts of the world and can generate significant environmental, economic and social benefits if managed with due regard to sustainability constraints. This work reviews the environmental, social and economic constraints on key feedstocks for UK heat, power and transport fuel. Key sustainability constraints include greenhouse gas savings achieved for different fuels, land availability, air quality impacts and facility siting. Applying those constraints, we estimate that existing technologies would facilitate a sustainability constrained level of medium-term bioenergy/biofuel supply to the UK of 4.9% of total energy demand, broken down into 4.3% of heat demands, 4.3% of electricity, and 5.8% of transport fuel. This suggests that attempts to increase the supply above these levels could have counterproductive sustainability impacts in the absence of compensating technology developments or identification of additional resources. The barriers that currently prevent this level of supply being achieved have been analysed and classified. This suggests that the biggest policy impacts would be in stimulating the market for heat demand in rural areas, supporting feedstock prices in a manner that incentivised efficient use/maximum greenhouse gas savings and targeting investment capital that improves yield and reduces land-take.

  2. [The Nature and Issues of Drug Addiction Treatment under Constraint].

    Science.gov (United States)

    Quirion, Bastien

    This article is exploring different forms of constraint that are exerted in the field of drug addiction treatment. The objective of this article is to establish benchmarks and to stimulate reflection about the ethical and clinical implications of those constraints in the field of drug addiction treatment. This article is presenting a critical review of different forms of constraint that can be exerted in Canada in regard to the treatment of drug addiction. In the first section of the article, a definition of therapeutic intervention is proposed, that includes the dimension of power, which justifies the importance of considering the coercive aspects of treatment. The second section, which represents the core section of the paper, is devoted to the presentation of different levels of constraint that can be distinguished in regard to drug addicts who are under treatment. Three levels of constraint are exposed: judicial constraint, institutional constraint and relational constraint. The coercive aspect of treatment can then be recognized as a combination of all tree levels of constraint. Judicial constraint refers to any form of constraint in which the court or the judge is imposing or recommending treatment. This particular level of constraint can take different forms, such as therapeutic remands, conditions of a probation order, conditions of a conditional sentence of imprisonment, and coercive treatment such as the ones provided through drug courts. Institutional constraint refers to any form of constraint exerted within any institutional setting, such as correctional facilities and programs offered in community. Correctional facilities being limited by their own specific mission, it might have a major impact on the way the objectives of treatment are defined. Those limitations can then be considered as a form of constraint, in which drug users don't have much space to express their personal needs. Finally, relational constraint refers to any form of constraint in

    This pilot study used a prospective longitudinal design to compare the effect of adjuvant whole breast radiation therapy (WBRT) versus partial breast radiation therapy (PBRT) on fatigue, perceived stress, quality of life and natural killer cell activity (NKCA) in women receiving radiation after breast cancer surgery. Women (N = 30) with early-stage breast cancer received either PBRT, Mammosite brachytherapy at dose of 34 Gy 10 fractions/5 days, (N = 15) or WBRT, 3-D conformal techniques at dose of 50 Gy +10 Gy Boost/30 fractions, (N = 15). Treatment was determined by the attending oncologist after discussion with the patient and the choice was based on tumor stage and clinical need. Women were assessed prior to initiation of radiation therapy and twice after completion of radiation therapy. At each assessment, blood was obtained for determination of NKCA and the following instruments were administered: Perceived Stress Scale (PSS), Functional Assessment of Cancer Therapy-Fatigue (FACT-F), and Functional Assessment of Cancer Therapy-General (FACT-G). Hierarchical linear modeling (HLM) was used to evaluate group differences in initial outcomes and change in outcomes over time. Fatigue (FACT-F) levels, which were similar prior to radiation therapy, demonstrated a significant difference in trajectory. Women who received PBRT reported progressively lower fatigue; conversely fatigue worsened over time for women who received WBRT. No difference in perceived stress was observed between women who received PBRT or WBRT. Both groups of women reported similar levels of quality of life (FACT-G) prior to initiation of radiation therapy. However, HLM analysis revealed significant group differences in the trajectory of quality of life, such that women receiving PBRT exhibited a linear increase in quality of life over time after completion of radiation therapy; whereas women receiving WBRT showed a decreasing trajectory. NKCA was also similar between therapy

    Full Text Available In this article we identified a number of factors influencing the consumers’ perceived risk. In the first part we conducted a review of the main issues that define the perceived risk by the consumer at the time of purchase, some of the lines of action of the organizations to diminish this risk perception and a number of influencing factors presented in the literature, with significant impact on the intensity with which risk is perceived by consumers. The second part of the article is based on the statistical information regarding e-commerce market, market in which the perceived risk plays an important role in the purchasing decision. Thus, based on available official statistics provided by Eurostat we have revealed the existence of certain links between electronic commerce and orientation towards risk and income levels, age and consumer educational level. The review is not intended to be exhaustive, the study taking into consideration only those links that can be identified from using official statistical data.

    A constraint satisfaction problem is a classical artificial intelligence paradigm characterized by a set of variables (each variable with an associated domain of possible values), and a set of constraints that specify relations among subsets of these variables. Solutions are assignments of values to all variables that satisfy all the constraints. Many real world problems may be modelled by means of constraints. The range of problems that can use this representation is very diverse and embrace...

    Studies have examined university students' fear of crime focusing on the relationship between the fear of sexual assault and fear of other crimes, termed the shadow of sexual assault hypothesis; however, no study to date has examined the shadow thesis in a Turkish context. Drawing on the shadow thesis, using a sample of 723 university students in Istanbul, this study focuses on the effect of fear of sexual assault and perceived risk of crime to general fear of crime among university students in Istanbul. Also, the predictors of fear of crime are explored to examine the relationship between lifestyle characteristics, constrained behaviors, and fear. The findings of the study supported the shadow thesis, indicating that fear of sexual assault shaped the nonsexual crimes, especially crimes involving face-to-face confrontations between the victim and offender. Furthermore, lifestyle characteristics are correlated with the men's fear of nonsexual crimes, particularly fear of robbery, aggravated assault, and burglary home.

    We study the complexity of constraint satisfaction problems for templates Γ that are first-order definable in ({ Z}; {suc}), the integers with the successor relation. Assuming a widely believed conjecture from finite domain constraint satisfaction (we require the tractability conjecture by Bulatov, Jeavons and Krokhin in the special case of transitive finite templates), we provide a full classification for the case that Γ is locally finite (i.e., the Gaifman graph of Γ has finite degree). We show that one of the following is true: The structure Γ is homomorphically equivalent to a structure with a certain majority polymorphism (which we call modular median) and CSP(Γ) can be solved in polynomial time, or Γ is homomorphically equivalent to a finite transitive structure, or CSP(Γ) is NP-complete.

    The GERRY scheduling system developed by NASA Ames with assistance from the Lockheed Space Operations Company, and the Lockheed Artificial Intelligence Center, uses a method called constraint-based iterative repair. Using this technique, one encodes both hard rules and preference criteria into data structures called constraints. GERRY repeatedly attempts to improve schedules by seeking repairs for violated constraints. The system provides a general scheduling framework which is being tested on two NASA applications. The larger of the two is the Space Shuttle Ground Processing problem which entails the scheduling of all the inspection, repair, and maintenance tasks required to prepare the orbiter for flight. The other application involves power allocation for the NASA Ames wind tunnels. Here the system will be used to schedule wind tunnel tests with the goal of minimizing power costs. In this paper, we describe the GERRY system and its application to the Space Shuttle problem. We also speculate as to how the system would be used for manufacturing, transportation, and military problems.

As a result, busts gradually become deeper than booms. Based...

    New research assessment frameworks that include societal impact criteria, also require the inclusion on non-academic evaluators (users) as part of the assessment panels. Little research has been conducted on how these user evaluators are received by traditionally academic-led panels, and how their presence influences evaluation outcomes. This is especially the case for evaluations including societal impact criteria. This article uses a mixed-methods approach to explore academic-evaluator concerns about the inclusion of user-evaluators in the assessment process. In addition, it explores how their involvement, influenced the outcomes of the evaluation process. (Author)

    Recent work has shown that Chinese Americans caring for a family member with dementia experience considerable psychological distress. However, few studies evaluate treatments for them. This study evaluated the efficacy of in-home intervention, based on cognitive behavior therapy principles, to relieve stress and depression in female Chinese American caregivers (CGs). Fifty-five CGs who met inclusion criteria were randomly assigned to a telephone support condition (TSC) or to an in-home behavioral management program (IHBMP) for 4 months. In the TSC, biweekly calls were made and relevant material was mailed. In the IHBMP, specific psychological skills were taught to deal with caregiving stress. CGs were assessed before and after treatment. Outcome measures evaluated overall perceived stress, caregiving-specific stress, and depressive symptoms. CGs in IHBMP were less bothered by caregiving-specific stressors and had lower depression levels than CGs in TSC. There was no difference in overall stress. CGs with low baseline level of self-efficacy for obtaining respite benefited from IHBMP, but showed little improvement in the TSC. CGs with higher self-efficacy benefited from both treatments. This intervention is promising and warrants replication in future studies. Additional research is needed to evaluate longer-term effects and to identify individual differences associated with improvement.

  13. Reduction Of Constraints For Coupled Operations

    The homogeneity constraint was implemented in the Defense Waste Processing Facility (DWPF) Product Composition Control System (PCCS) to help ensure that the current durability models would be applicable to the glass compositions being processed during DWPF operations. While the homogeneity constraint is typically an issue at lower waste loadings (WLs), it may impact the operating windows for DWPF operations, where the glass forming systems may be limited to lower waste loadings based on fissile or heat load limits. In the sludge batch 1b (SB1b) variability study, application of the homogeneity constraint at the measurement acceptability region (MAR) limit eliminated much of the potential operating window for DWPF. As a result, Edwards and Brown developed criteria that allowed DWPF to relax the homogeneity constraint from the MAR to the property acceptance region (PAR) criterion, which opened up the operating window for DWPF operations. These criteria are defined as: (1) use the alumina constraint as currently implemented in PCCS (Al 2 O 3 (ge) 3 wt%) and add a sum of alkali constraint with an upper limit of 19.3 wt% (ΣM 2 O 2 O 3 constraint to 4 wt% (Al 2 O 3 (ge) 4 wt%). Herman et al. previously demonstrated that these criteria could be used to replace the homogeneity constraint for future sludge-only batches. The compositional region encompassing coupled operations flowsheets could not be bounded as these flowsheets were unknown at the time. With the initiation of coupled operations at DWPF in 2008, the need to revisit the homogeneity constraint was realized. This constraint was specifically addressed through the variability study for SB5 where it was shown that the homogeneity constraint could be ignored if the alumina and alkali constraints were imposed. Additional benefit could be gained if the homogeneity constraint could be replaced by the Al 2 O 3 and sum of alkali constraint for future coupled operations processing based on projections from Revision 14 of

    This pilot double-blind sham-controlled randomized trial aimed to determine if the addition of anodal tDCS on the affected hemisphere or cathodal tDCS on unaffected hemisphere to modified constraint-induced movement therapy (mCIMT) would be superior to constraints therapy alone in improving upper limb function in chronic stroke patients. Twenty-one patients with chronic stroke were randomly assigned to receive 12 sessions of either (i) anodal, (ii) cathodal or (iii) sham tDCS combined with mCIMT. Fugl-Meyer assessment (FMA), motor activity log scale (MAL), and handgrip strength were analyzed before, immediately, and 1 month (follow-up) after the treatment. Minimal clinically important difference (mCID) was defined as an increase of ≥5.25 in the upper limb FMA. An increase in the FMA scores between the baseline and post-intervention and follow-up for active tDCS group was observed, whereas no difference was observed in the sham group. At post-intervention and follow-up, when compared with the sham group, only the anodal tDCS group achieved an improvement in the FMA scores. ANOVA showed that all groups demonstrated similar improvement over time for MAL and handgrip strength. In the active tDCS groups, 7/7 (anodal tDCS) 5/7 (cathodal tDCS) of patients experienced mCID against 3/7 in the sham group. The results support the merit of association of mCIMT with brain stimulation to augment clinical gains in rehabilitation after stroke. However, the anodal tDCS seems to have greater impact than the cathodal tDCS in increasing the mCIMT effects on motor function of chronic stroke patients. The association of mCIMT with brain stimulation improves clinical gains in rehabilitation after stroke. The improvement in motor recovery (assessed by Fugl-Meyer scale) was only observed after anodal tDCS. The modulation of damaged hemisphere demonstrated greater improvements than the modulation of unaffected hemispheres.

    As a common mental disorder, depressive symptoms had been studied extensively all over the world. However, positive resources for combating depressive symptoms among Chinese doctors were rarely studied. Our study aimed to investigate the relationships between work-family conflict (WFC) and family-work conflict (FWC) with depressive symptoms among Chinese doctors. Meanwhile, the role of perceived organizational support (POS) in this association was explored at an organizational level. The investigation was conducted between March and April 2014. Questionnaires that measured WFC, FWC, depressive symptoms and POS were distributed to 1200 doctors in Shenyang, China. The final study subjects were 931 doctors (effective response rate: 77.6%). In all analyses, male and female doctors were analyzed separately because of possible gender differences. Hierarchical linear regression analyses were used to examine the moderating role of POS. Baron and Kenny's technique and asymptotic and resampling strategies were used to explore the mediating role of POS on the associations of WFC or FWC with depressive symptoms. WFC and FWC had positive relations with depressive symptoms among doctors. POS played a partial mediating role on the correlation of FWC with depressive symptoms among male doctors, and POS played a partial mediating role on the correlation of WFC with depressive symptoms among female doctors. POS had a positive moderating effect on the relationship between WFC and depressive symptoms among doctors. WFC and FWC could aggravate doctors' depressive symptoms, and POS, as an organizational resource, could fight against doctors' depressive symptoms. When POS functioned as a mediator, FWC had a negative effect on POS, which could increase male doctors' depressive symptoms, and WFC had a negative effect on POS, which could increase female doctors' depressive symptoms. In the meantime, POS, as a moderator, could enhance the effects of WFC on depressive symptoms.

    Most modern industrial and architectural designs need to satisfy the requirements of their targeted performance and respect the limitations of available fabrication technologies. At the same time, they should reflect the artistic considerations and personal taste of the designers, which cannot be simply formulated as optimization goals with single best solutions. This thesis aims at a general, flexible yet e cient computational framework for interactive creation, exploration and discovery of serviceable, constructible, and stylish designs. By formulating nonlinear engineering considerations as linear or quadratic expressions by introducing auxiliary variables, the constrained space could be e ciently accessed by the proposed algorithm Guided Projection, with the guidance of aesthetic formulations. The approach is introduced through applications in different scenarios, its effectiveness is demonstrated by examples that were difficult or even impossible to be computationally designed before. The first application is the design of meshes under both geometric and static constraints, including self-supporting polyhedral meshes that are not height fields. Then, with a formulation bridging mesh based and spline based representations, the application is extended to developable surfaces including origami with curved creases. Finally, general approaches to extend hard constraints and soft energies are discussed, followed by a concluding remark outlooking possible future studies.

    The authors have analyzed general properties of very long DNA sequences belonging to simple and complex organisms, by using different correlation methods. They have distinguished those base compositional rules that concern the entire genome which they call `genomic constraints` from the rules that depend on the `external natural selection` acting on single genes, i. e. protein-centered constraints. They show that G + C content, purine / pyrimidine distributions and biological complexity of the organism are the most important factors which determine base compositional rules and genome complexity. Three main facts are here reported: bacteria with high G + C content have more restrictions on base composition than those with low G + C content; at constant G + C content more complex organisms, ranging from prokaryotes to higher eukaryotes (e.g. human) display an increase of repeats 10-20 nucleotides long, which are also partly responsible for long-range correlations; work selection of length 3 to 10 is stronger in human and in bacteria for two distinct reasons. With respect to previous studies, they have also compared the genomic sequence of the archeon Methanococcus jannaschii with those of bacteria and eukaryotes: it shows sometimes an intermediate statistical behaviour.
