    Since disabled persons increase with a progress of an aging society, while a care power decreases with a decrease in birth rate, development and practical use of the welfare equipment contributing to self-support of aged and handicapped persons, reduction of doctors' or therapists' burdens, and as a result, reduction of medical care costs are desirable. Among them, R and D and practical use are expected of the advanced welfare equipment and system based on human engineering technology contributing to improvement of lives of aged and handicapped persons, and support of nurses and cares of disabled persons. In fiscal 1998, on both human friendly care support intelligent equipment and home welfare equipment system, this project clarified essential technical issues based on the future view, selected some themes to be newly developed in the future, and surveyed and evaluated the details of their R and D concretely. For the former, 'heart disease diagnosis and treatment total support system,' and for the latter, 'body function rehabilitation support system' were surveyed. (NEDO)

    A frailty index for Japanese older people is not yet available. This study examined the validity of "Kaigo-Yobo Check-List" (CL) as a frailty index. The study site was Kusatsu town, Gunma prefecture. Out of 612 older persons aged 65 years and over who undertook a comprehensive geriatric assessment in 2007, results from 526 who had no missing data were used to examine the cross-sectional relationship between frailty as defined by Fried's criteria (= external criteria) and CL scores in order to evaluate concurrent and construct validity. Further, 916 older individuals aged 70 years and over who responded to the baseline survey in 2001 were followed for the subsequent 4 years and 4 months regarding the onset of ADL disability, service use under the Long Term Care Insurance program, and mortality. We examined the predictive validity of the CL for such adverse outcomes after adjustment for gender, age, and comorbidity. The CL (cut-off point = 3/4) discriminated frailty from non-frailty at the sensitivity of 70.0% and specificity of 89.3%. The higher the CL score, the higher the prevalence of frailty; the trend was highly significant (P Check-List" showed good concurrent and predictive validity as a frailty index. Since it comprises 15 easy-to-answer questions, it could be widely used for research on frailty and its preventive intervention.

    2014-12-01

    Full Text Available One of Fay Weldon’s early novels, Female Friends (1975, published at the peak of her feminist ’phase’, deconstructs female and feminine stereotypes in order to present the writer’s own views on feminism. It speaks for a generation of women, who struggle to find their place in a male-dominated world, through three protagonists, who are neither happy, nor perfect. Narrated by the character Chloe, the novel revolves around her and her friends, Grace and Marjorie, with an aim at depicting the falsehood and hypocrisy that surround female friendship. It is precisely where Weldon’s specificity as a feminist writer lies: in her rendering the imperfections of women’s characters and relationships. This paper attempts to trace such elements of ‘fayminism’ in Female Friends by resorting to the tools of the feminist critic.

    This paper summarizes the research results on the friendly network robotics in fiscal 1996. This research assumes an android robot as an ultimate robot and the future robot system utilizing computer network technology. The robot aiming at human daily work activities in factories or under extreme environments is required to work under usual human work environments. The human robot with similar size, shape and functions to human being is desirable. Such robot having a head with two eyes, two ears and mouth can hold a conversation with human being, can walk with two legs by autonomous adaptive control, and has a behavior intelligence. Remote operation of such robot is also possible through high-speed computer network. As a key technology to use this robot under coexistence with human being, establishment of human coexistent robotics was studied. As network based robotics, use of robots connected with computer networks was also studied. In addition, the R-cube (R{sup 3}) plan (realtime remote control robot technology) was proposed. 82 refs., 86 figs., 12 tabs.

    2018-03-09

    Background Lipedema is a chronic disorder presenting in women during puberty or other times of hormonal change such as childbirth or menopause, characterized by symmetric enlargement of nodular, painful subcutaneous adipose tissue (fat) in the limbs, sparing the hands, feet and trunk. Healthcare providers underdiagnose or misdiagnose lipedema as obesity or lymphedema. Materials and methods The benefits (friend) and negative aspects (foe) of lipedema were collected from published literature, discussions with women with lipedema, and institutional review board approved evaluation of medical charts of 46 women with lipedema. Results Lipedema is a foe because lifestyle change does not reduce lipedema fat, the fat is painful, can become obese, causes gait and joint abnormalities, fatigue, lymphedema and psychosocial distress. Hypermobility associated with lipedema can exacerbate joint disease and aortic disease. In contrast, lipedema fat can be a friend as it is associated with relative reductions in obesity-related metabolic dysfunction. In new data collected, lipedema was associated with a low risk of diabetes (2%), dyslipidemia (11.7%) and hypertension (13%) despite an obese average body mass index (BMI) of 35.3 ± 1.7 kg/m2. Conclusion Lipedema is a painful psychologically distressing fat disorder, more foe than friend especially due to associated obesity and lymphedema. More controlled studies are needed to study the mechanisms and treatments for lipedema.

    Full Text Available Environmental pollution is a major problem in developing countries like Egypt. Reuse of waste polymers is considered an attractive solution for environmental white pollution and reducing of the costs of road pavement and maintenance. This research aims to prepare environmentally friendly hot mix asphalt (HMA for paving using some industrial wastes as polypropylene and polyester fibers. The solid materials in the mix include normal and highly porous aggregates. 5% and 10% of waste polymers by weight of the asphalt were used to prepare special binders. The samples were tested for their physical properties, chemical properties, aging, scanning electron microscopy (SEM and thermo-gravimetric analysis (TGA. The results revealed that the prepared HMA using 5% of waste polymer had high performance as compared to the ordinary one and the waste polymer could be used in road construction.

    The debate on the safety of and regulatory approaches for caffeine continues among various stakeholders and regulatory authorities. This decision-making process comes with significant challenges, particularly when considering the complexities of the available scientific data, making the formulation of clear science-based regulatory guidance more difficult. To allow for discussions of a number of key issues, the North American Branch of the International Life Sciences Institute (ILSI) convened a panel of subject matter experts for a caffeine-focused session entitled "Caffeine: Friend or Foe?," which was held during the 2015 ILSI Annual Meeting. The panelists' expertise covered topics ranging from the natural occurrence of caffeine in plants and interindividual metabolism of caffeine in humans to specific behavioral, reproductive, and cardiovascular effects related to caffeine consumption. Each presentation highlighted the potential risks, benefits, and challenges that inform whether caffeine exposure warrants concern. This paper aims to summarize the key topics discussed during the session.

  16. Cyber Friendly Fire

    Energy Technology Data Exchange (ETDEWEB)

    Greitzer, Frank L.; Carroll, Thomas E.; Roberts, Adam D.

    2011-09-01

    Cyber friendly fire (FF) is a new concept that has been brought to the attention of Department of Defense (DoD) stakeholders through two workshops that were planned and conducted by the Air Force Research Laboratory (AFRL) and research conducted for AFRL by the Pacific Northwest National Laboratory. With this previous work in mind, we offer a definition of cyber FF as intentional offensive or defensive cyber/electronic actions intended to protect cyber systems against enemy forces or to attack enemy cyber systems, which unintentionally harms the mission effectiveness of friendly or neutral forces. Just as with combat friendly fire, a fundamental need in avoiding cyber FF is to maintain situation awareness (SA). We suggest that cyber SA concerns knowledge of a system's topology (connectedness and relationships of the nodes in a system), and critical knowledge elements such as the characteristics and vulnerabilities of the components that comprise the system (and that populate the nodes), the nature of the activities or work performed, and the available defensive (and offensive) countermeasures that may be applied to thwart network attacks. A training implication is to raise awareness and understanding of these critical knowledge units; an approach to decision aids and/or visualizations is to focus on supporting these critical knowledge units. To study cyber FF, we developed an unclassified security test range comprising a combination of virtual and physical devices that present a closed network for testing, simulation, and evaluation. This network offers services found on a production network without the associated costs of a real production network. Containing enough detail to appear realistic, this virtual and physical environment can be customized to represent different configurations. For our purposes, the test range was configured to appear as an Internet-connected Managed Service Provider (MSP) offering specialized web applications to the general public

    2009-06-15

    Environmental protection has become an integral part of the entire cask life cycle: - Design and Fabrication; - Transportation; - Loading, Unloading and Operation; - Maintenance, End of Life Cycle and Dismantling. Three new environmentally-friendly cask concepts were developed: the MX6, the TN112 and the multipurpose Shell. Eco design approach was used to reduce their environmental impacts and address environmental issues such as waste generation and management, greenhouse gases linked to transportation, and scarcity of raw materials, all while improving operating performance. The result is greater responsiveness to the customer and a more comprehensive approach to potential regulatory changes. The cask design optimizes all of the impacting factors, such as raw materials quantity, radiological protection capacity, and the use of more environmentally-friendly materials and fabrication processes. To illustrate, the new MX6 concept may be compared to the standard FS65 concept. In the area of Design and Fabrication, the MX6 requires fewer raw materials and can lower the cask weight/transported assembly weight ratio. An adjustable basket concept was developed. - The new cask is also more effective in terms of radiation protection as a result of improved materials performance. - In the area of fabrication, all waste is transferred to suitable processing systems that promote recycling. In the area of Transportation, shipments are reduced by 33%, thus reducing diesel fuel consumption and greenhouse gas emissions. Also, in the area of Operations, the amount of waste generated per assembly shipped is minimized, as are the number of operations and the time spent on them by the operators. In the area of Maintenance and Dismantling, extensive, time-consuming maintenance operations are minimized, as is the waste generated by them. The TN112 cask reduces exposure by 15%, uses fewer raw materials, and has a faster turnaround time due to optimized tooling. For waste subject to

    2011-09-01

    On the political and policy front, interest has increased in making communities more "age-friendly", an ongoing trend since the World Health Organization launched its global Age-Friendly Cities project. We conceptualize age-friendly communities by building on the WHO framework and applying an ecological perspective. We thereby aim to make explicit key assumptions of the interplay between the person and the environment to advance research or policy decisions in this area. Ecological premises (e.g., there must be a fit between the older adult and environmental conditions) suggest the need for a holistic and interdisciplinary research approach. Such an approach is needed because age-friendly domains (the physical environment, housing, the social environment, opportunities for participation, informal and formal community supports and health services, transportation, communication, and information) cannot be treated in isolation from intrapersonal factors, such as age, gender, income, and functional status, and other levels of influence, including the policy environment.

    Full Text Available Critical friends: a method for peer feedback The Critical Friend-method has been used in various educational settings to facilitate the process of continuous improvement in teaching. The aim of this study was to implement Critical Friends, and to find out if this method could be used for feedback on teaching as part of a librarians' professional development. The project was carried out within the Library Unit of the Faculty of Medicine at Lund University, Sweden, in collaboration with the faculty's Centre for Teaching and Learning. Seven librarians and an educational consultant from the Centre for Teaching and Learning participated; the educational consultant played an essential role in supervising and structuring the project and the evaluation process, preparing readings as well as being an active participant. The participants worked in pairs; the performance of one teacher and the associated classroom activities were observed by the critical friend, and then evaluated and discussed. Evaluation and results After two preparatory group meetings, a final meeting was held where all pairs reported what they had done and how they perceived the critical friend process. The experiences of the participating librarians were explored using a questionnaire. The questionnaire was analyzed using content analysis by one librarian and the educational consultant independently. The results suggested that use of the critical friend method could have a positive impact by achieving the following: strengthening shared values concerning teaching issues; promoting self-reflection on teaching; facilitating communication with colleagues; and reducing the sense of 'loneliness‘ in teaching. The difficulties in the implementation were lack of time and competing duties. It was perceived as an advantage to work in close partnership with the faculty's educational consultants, who were familiar with the organization.

    2016-07-01

    Sociologists of education have long been interested in the effects of peer relations on educational outcomes. Recent theory and research on adolescence suggest that peers on the boundaries of students' friendship networks may play an important role in shaping behaviors and educational outcomes. In this study, we examine the importance of a key "intermediate peer context" for students' outcomes: the friends of a student's friends. Our findings indicate both friends' and friends' friends' characteristics independently predict students' college expectations and their risk of dropping out of high school (although only friends' characteristics predict GPA). Our models suggest the magnitude of students' friends-of-friends' characteristics are at least as large their friends' characteristics. Together, the association between the peer context and students outcomes is considerably larger when accounting for both the characteristics of students' friends and the friends of their friends.

    The objective of the Ground Systems Development and Operations Program Environmentally Friendly Corrosion Protective Coatings and Corrosion Preventive Compounds (CPCs) project is to identify, test, and develop qualification criteria for the use of environmentally friendly corrosion protective coatings and CPCs for flight hardware and ground support equipment. This document is the Final Report for Phase I evaluations, which included physical property, corrosion resistance, and NASA spaceport environment compatibility testing and analysis of fifteen CPC types. The CPCs consisted of ten different oily film CPCs and five different wax or grease CPC types. Physical property testing encompassed measuring various properties of the bulk CPCs, while corrosion resistance testing directly measured the ability of each CPC material to protect various metals against corrosion. The NASA spaceport environment compatibility testing included common tests required by NASA-STD-6001, "Flammability, Odor, Offgassing, and Compatibility Requirements and Test Procedures for Materials in Environments that Support Combustion". At the end of Phase I, CPC materials were down-selected for inclusion in the next test phases. This final report includes all data and analysis of results obtained by following the experimental test plan that was developed as part of the project. Highlights of the results are summarized by test criteria type.

    Most soft drinks contain high concentration of simple carbohydrates and have a pH of 3 or even lower. Therefore, they are harmful for tooth structure. A tooth friendly soft drink (T.F.S.D) should have the following characteristics and elements; fluoride (approximately 1 ppm), casein phosphopeptide-amorphous calcium phosphate (2%), xylitol (4-6g/serving), tea polyphenols (2-4 mg/ml), cranberry extract (250 mg/ml of the flavonoids quercetin and myricetin), sugar free, pH close to 5.5 and super oxygenation (240,000 ppm) vs. carbonation. T.F.S.D can be packaged in a container which gaseous oxygen is dissolved in a liquid in the form of bubbles. However, looking at opportunities for so-called sophisticated soft drinks, T.F.S.D will be an example for a functional and health oriented soft drink.

    To evaluate the qualitative aspects of the Hispanic Labor Friends Initiative. "Hispanic Labor Friends," bilingual Hispanic community women who were themselves mothers, were recruited by clinic and hospital personnel. Women who agreed were educated, received translation certification, and were oriented to the initiative. Pregnant Hispanic immigrant women seen in the health center who met criteria set by the multidisciplinary health care team were assigned a Hispanic Labor Friend by 32 weeks' gestation. Hispanic Labor Friends assisted women with communication with healthcare providers and provided social support. Qualitative evaluation of the program consisted of interviews with several groups: (1) Hispanic immigrant women who had a Hispanic Labor Friend, (2) Hispanic immigrant women who were not in the Hispanic Labor Friends program, (3) Hispanic Labor Friends, (4) healthcare providers for Hispanic women. Data saturation was reached, and data were analyzed by the research team using descriptive qualitative inquiry. The Hispanic immigrant women described positive outcomes from being involved in the Hispanic Labor Friends program, including feeling supported and comforted. "I felt as though my family were at my side." One woman who had standard care said, "It is hard for me to communicate. When I gave birth, the nurses asked me things, and I didn't understand anything. I stayed quiet." One of the nurses who was interviewed said: "I think they [the HLF patients] get better care. Sometimes we think we can communicate with them with their little bit of English and our little bit of Spanish. But you get an HLF and it's a totally different story. We can more adequately tell what's going on with them...They end up getting better care." One Hispanic Labor Friend said, "The women are very appreciative that I was there to help them through a critical time." Women who participated in the study identified the need to have a continuing association with Hispanic Labor Friends in

    The present study examined associations between use of protective behavioral strategies (PBS) by college students and their friends and drinking-related outcomes during Spring Break (SB). Moreover, this study examined the influence of friends' own PBS use on participants' PBS use during SB. Participants included college students (N = 694) and their nominated friends (N = 131) who were part of a larger study of SB drinking. Data were collected via web-based surveys that participants and friends took after SB, which assessed SB PBS, drinking, and related negative consequences. Results indicated that higher levels of Serious Harm Reduction (SHR) strategies and Limiting/Stopping (LS) strategies were associated with increased consumption, higher likelihood of experiencing any consequences, and an increased number of consequences. A different pattern emerged for Manner of Drinking (MD) strategy use; participants utilizing higher levels of MD strategies drank less and had fewer consequences. LS and MD strategies used by the participant's friends appeared to have less of an impact on the participant's drinking outcomes. However, greater friends' use of SHR strategies was associated with increased alcohol use by the participant, but not with consequences. Greater friends' use of SHR strategies was associated with greater SHR strategy use by the participant. Friends' LS and MD strategies were not associated with participant drinking, consequences, or PBS. These findings highlight the potential utility of interventions that focus on drinking behaviors on specific high-risk occasions for those at risk as well as for their friends.

    2016-06-01

    Research purpose: To determine the environmentally-friendly practices in hotels in Zimbabwe and South Africa and establish the contribution that hotels are making towards mitigation of the negative environmental effects. Motivation for the study: Currently, the world is facing environmental issues, which include global climate change, ozone depletion, pollution, high consumption of resources and increasing amounts of solid waste. Hotels, as part of the tourism industry, exert a significant impact on the environment. While the extent and range of the impact that hotels exert on the environment suggest an urgent need to address this problem, the question that arises is whether hoteliers appreciate the need for environmentally-friendly initiatives in their establishments. Research design, approach and method: A qualitative research was carried out in eight hotels that employ the strategy of the case study in the aforementioned countries. Main findings: Currently, no policies for green management exist, although some hotels do engage in some environmentally-friendly practices. Some hotel managers do not implement green management initiatives to mitigate the environmental problems emanating from their hotel operations. Practical and/or managerial implications: This indicates that a gap exists between managers’ awareness of appropriate environmentally-friendly practices for hotels, implying a need for training and increased awareness of green management. Contribution and/or value-add: The results could guide managers in the implementation of environmentally-friendly practices in an effort to mitigate environmental problems facing the present generation.

    Little is known about how interpersonal friend relationships are associated with obesity in young people, particularly with regard to how race/ethnicity, type of friendship, and sex affect the association between friends' and adolescents' weight status. This study examined associations in weight status among adolescents and their friends, exploring magnitudes of associations across friendship type, sex, and race/ethnicity. As part of EAT-2010 (Eating and Activity in Teens), friend nominations and anthropometrics were obtained from adolescents (n = 2099: 54% female; 80% nonwhite; mean age: 14.2 ± 1.9 years). Generalized estimating equation logistic regression models were used to test associations between adolescents' overweight/obese status and friends' (i.e., friend group, female friends, male friends, female best friends, and male best friends) overweight/obese status. Interactions by adolescent race/ethnicity were examined. The majority of significant associations were observed among white female adolescents' who had a 22-40% higher prevalence of overweight/obesity if their friends were overweight compared to white females whose friends were not overweight. In contrast, there were few significant differences for other adolescent female and male racial/ethnic groups for girls and boys. Results for friend groups and best friends were generally similar to one another. The association between friend and adolescent overweight/obese status depended on adolescents' sex, race/ethnicity, and friendship type. Given the similarities among friends, obesity interventions targeting youth, especially white females, should consider involving friends.

    2014-07-01

    This study conducted comparative assessment of friendship in preschoolers with high-functioning autism spectrum disorder (HFASD, n = 29) versus preschoolers with typical development (n = 30), focusing on interactions with friends versus acquaintances. Groups were matched on SES, verbal/nonverbal MA, IQ, and CA. Multidimensional assessments included: mothers' and teachers' reports about friends' and friendship characteristics and observed individual and dyadic behaviors throughout interactions with friends versus non-friends during construction, drawing, and free-play situations. Findings revealed group differences in peer interaction favoring the typical development group, thus supporting the neuropsychological profile of HFASD. However, both groups' interactions with friends surpassed interactions with acquaintances on several key socio-communicative and intersubjective capabilities, thus suggesting that friendship may contribute to enhancement and practice of social interaction in HFASD.

    LGBT (lesbian, gay, bisexual, transgender) patients suffer from stigma and discrimination when seeking healthcare. A large LGBT healthcare survey revealed that 56% of gay patients and 70% of transgender patients suffered some type of discrimination while seeking healthcare in 2014. The fostering of LGBT-friendly healthcare services is not just an advanced step of gender mainstreaming but also a fulfillment of health equality and equity. Additionally, LGBT-friendly healthcare services are expected to provide new opportunities for healthcare workers. Therefore, proactive government policies, education, research, and clinical practice should all encourage the development of these healthcare services. We look forward to a well-developed LGBT-friendly healthcare system in Taiwan.

    2016-01-01

    In this paper, a standard susceptible-infected-recovered-susceptible(SIRS) epidemic model based on the Watts–Strogatz (WS) small-world network model and the Barabsi–Albert (BA) scale-free network model is established, and a new immunization scheme — “the most common friend first immunization” is proposed, in which the most common friend’s node is described as being the first immune on the second layer protection of complex networks. The propagation situations of three different immunization schemes — random immunization, high-risk immunization, and the most common friend first immunization are studied. At the same time, the dynamic behaviors are also studied on the WS small-world and the BA scale-free network. Moreover, the analytic and simulated results indicate that the immune effect of the most common friend first immunization is better than random immunization, but slightly worse than high-risk immunization. However, high-risk immunization still has some limitations. For example, it is difficult to accurately define who a direct neighbor in the life is. Compared with the traditional immunization strategies having some shortcomings, the most common friend first immunization is effective, and it is nicely consistent with the actual situation. (paper)

    Young people's engagement in political discussions with parents and friends represents a significant component of the political socialization process and can be seen as an activity where they learn some very basic democratic skills. Based on data from qualitative interviews and a questionnaire...... survey, this article explores how young people experience political discussions in their everyday life. Our data indicate that young people who feel that their father, mother or friends, respectively, hold more distant political views are less likely to engage in political discussions with each of them....... These findings support previous studies in political communication suggesting that people tend to avoid social situations where political disagreements are likely to appear. Furthermore, the results show that there are significant gender differences when analysing the role of the parents as political discussion...

    2017-10-01

    Best friends exert a substantial influence on rising alcohol and marijuana use during adolescence. Two mechanisms occurring within friendship - friend pressure and unsupervised co-deviancy - may partially capture the way friends influence one another. The current study aims to: (1) examine the psychometric properties of a new instrument designed to assess pressure from a youth's best friend and unsupervised co-deviancy; (2) investigate the relative contribution of these processes to alcohol and marijuana use; and (3) determine whether gender moderates these associations. Data were collected through self-report questionnaires completed by 294 Canadian youths (62% female) across two time points (ages 15-16). Principal component analysis yielded a two-factor solution corresponding to friend pressure and unsupervised co-deviancy. Logistic regressions subsequently showed that unsupervised co-deviancy was predictive of an increase in marijuana use one year later. Neither process predicted an increase in alcohol use. Results did not differ as a function of gender. Copyright © 2017 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd. All rights reserved.

  7. I and My Friends are Good People: The Perception of Incivility by Self, Friends and Strangers

    Directory of Open Access Journals (Sweden)

    Ursula Hess

    2016-02-01

    Full Text Available Three studies were conducted to assess self-serving biases in participants’ beliefs about incivility, its antecedents and consequences as well as restitution behaviors and forgiveness as a function of whether a behavior was performed by themselves, strangers or friends. Participants who imagined themselves in the active role not only described their own behavior as more excusable, congruent with an actor-observer bias, but more importantly, they showed strong self-serving biases with regard to all their reactions to the situation – even though this leads to logical contradictions. This self-serving expectation generalized to friends and contrasted sharply with expectations for strangers, whose behaviors were described as logically consistent. The difference between what is expected from self and friends and what is expected from others may account for much of the popular moral outrage at incivility in various social realms.

    2008-08-01

    Full Text Available Abstract The mass media have the potential to be powerful friends or foes in promoting breastfeeding. The media could help by putting the issue of breastfeeding on policy agendas and by framing breastfeeding as healthy and normative for baby and mother. Currently, however, it looks as if the media are more often contributing to perceptions that breastfeeding is difficult for mothers and potentially dangerous for babies. This paper presents a brief overview of research on the media and breastfeeding, some insights into the market forces and human psychological factors that may play into media representations of breastfeeding, and strategies to help breastfeeding advocates work more effectively with the media.

    Maturo, Claire C; Cunningham, Solveig A

    2013-07-01

    We examined evidence for friendship influences on children's physical activity (PA) through systematic searches of online databases in May 2012. We identified 106 studies (25 qualitative) published in English since 2000 that analyzed indicators of friendship influences (e.g., communication about PA, friends' PA, and PA with friends) among persons younger than 19 years. Children's PA was positively associated with encouragement from friends (43 of 55 studies indicating a positive relationship), friends' own PA (30/35), and engagement with friends in PA (9/10). These findings are consistent with friends influencing PA, but most studies did not isolate influence from other factors that could explain similarity. Understanding friendship influences in childhood can facilitate the promotion of lifelong healthy habits. PA with friends should be considered in health promotion programs.

  13. Friend Effects and Racial Disparities in Academic Achievement

    Directory of Open Access Journals (Sweden)

    Jennifer Flashman

    2014-07-01

    Full Text Available Racial disparities in achievement are a persistent fact of the US educational system. An often cited but rarely directly studied explanation for these disparities is that adolescents from different racial and ethnic backgrounds are exposed to different peers and have different friends. In this article I identify the impact of friends on racial and ethnic achievement disparities. Using data from Add Health and an instrumental variable approach, I show that the achievement characteristics of youths’ friends drive friend effects; adolescents with friends with higher grades are more likely to increase their grades compared to those with lower-achieving friends. Although these effects do not differ across race/ethnicity, given differences in friendship patterns, if black and Latino adolescents had friends with the achievement characteristics of white students, the GPA gap would be 17 to 19 percent smaller. Although modest, this effect represents an important and often overlooked source of difference among black and Latino youth.

    Full Text Available The paper focuses on identifying the methods useful for improving the process of creating an innovation ­friendly environment. For this purpose, conditions for innovation activity in industry were investigated, and the expert evaluation of the selected knowledge and the assessment of the importance of skills for the successful development of innovations were car­ ried out. The work referred to the analysis of the sources of scientific information, a sociological inquiry of the personnel of industrial enterprises, correlation analysis and expert evaluation. The study has found that for building the innovation ­friendly environment, knowledge of the psychology of creativity, personnel management, formation and implementation of the innova­ tion strategy, risk management, business development and sales organization are of a particular importance. Expert assessment has showed that abilities to work in a team, be an entrepreneur, use marketing tools, generate ideas and create new products play a crucial role in innovation development. A situation in industry companies has shown the currently existing various groups of employees with a different point of view on the surveyed parameter. Managers, workers, engineers and other staff have different opinions and knowledge, and therefore a well thought­out policy is required for wider innovative activities. The directives of such a policy must be available for everyone.

    2002-01-01

    This project assesses the possibilities of constructing a market for climate-friendly energy technologies by applying the process of 'societal embedding of innovations'. The term refers to an interactive learning process amongst three groups of key actors: producers, users and societal actors. Their co-operation shapes the innovation to fit the needs of the market and contributes to creation of conditions in which the innovation can be adopted. The project consists of two case studies: (1) Shaping of the ESCO energy service concept in Finnish municipalities and (2) Increasing the use of wood pellets in single-family houses. The case studies have illustrated the possibilities and limitations concerning the application of societal embedding in the energy sector. The project indicates that societal embedding may promote the implementation of climate-friendly energy technologies in at least three ways. Firstly, the process mobilises key actors to cooperation. This generates interactive learning on the problem and its solving. Market construction is forged ahead by mutual adaptation of the innovation and its environment. Secondly, this approach offers a tool to examine the societal quality of the innovation, a question related vitally to climate change. Thirdly, by producing new knowledge of the needs on the market this approach supports the societal actors in choosing different instruments to induce the intended transition to sustainability.

    Han, Sohyun C; Margolin, Gayla

    2016-06-01

    This study investigated whether having friends who engaged in more prosocial than antisocial behaviors buffered the associations between family-of-origin aggression and later victimization. Adolescent participants ( N =125) and their parents reported on different types of family aggression in early adolescence. Approximately 5 years later, adolescents reported on their victimization experiences with dating partners and friends, and their friends' prosocial and antisocial behaviors. Only father-to-child aggression was significantly associated with dating and friend victimization, with stronger risk for females' dating victimization. Moreover, having friends who engaged in more prosocial than antisocial behaviors had both a direct inverse relationship with dating partner victimization. This also buffered the risk for dating victimization associated with father-daughter aggression. Findings suggest that greater attention be paid to the father-daughter relationship and to the importance of having friends who engage in prosocial behaviors in the prevention of adolescents' victimization.

    Waesterlund, I.; Hassan, A.E.

    1995-01-01

    The trend in forestry practices today in Europe and U.S.A. in general and Scandinavian countries in particular, is towards adapting systems based on landscape planning. Thus common harvesting equipment available on the market will have to be replaced to meet these tough demands. Environmentalists recommend that wood fiber should be harvested either by selection cutting or commercial thinning thus leaving the site undisturbed with no sign of machine traffic. This mandate will preserve ground water quality and assist in soil conservation. However, to meet the pulp and paper as well as saw mill industries demand for wood from this method of cutting (selection or commercial thinning), requires a thorough examination of our harvesting systems and techniques. This paper will discuss present and future machines that are friendly to the environment. Hypothetical designs and improvements of existing machine systems will be addressed and recommendations will be made for future research activities. 75 refs, 8 figs, 1 tab

  19. Autophagy in endometriosis: Friend or foe?

    Science.gov (United States)

    Zhan, Lei; Li, Jun; Wei, Bing

    2018-01-01

    Endometriosis is a chronic, estrogen-dependent disease and characterized by the implantation of endometrial glands and stroma deep and haphazardly into the outside the uterine cavity. It affects an estimated 10% of the female population of reproductive age and results in obvious reduction in health-related quality of life. Unfortunately, there is no a consistent theory for the etiology of endometriosis. Furthermore, the endometriosis is hard to diagnose in early stage and the treatment methods are limited. Importantly, emerging evidence has investigated that there is a close relationship between endometriosis and autophagy. However, autophagy is a friend or foe in endometriosis is puzzling, the precise mechanism underlying autophagy in endometriosis has not been fully elucidated yet. Here, we provide an integrated view on the acquired findings of the connections between endometriosis and autophagy. We also discuss which may contribute to the abnormal level of autophagy in endometriosis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Dieting, unhealthy weight control and muscle-enhancing behaviors are common among adolescents: friends are a probable source of influence on these behaviors. The present study uses data provided by nominated friends to examine associations between friends' disordered eating and muscle-enhancing behaviors and participants' own behaviors in a diverse sample of American youth. Male and female adolescents (mean age = 14.4) completed surveys and identified their friends from a class roster; friends' survey data were then linked to each participant. Participants (N = 2126) who had at least one nominated friend were included in the analytic sample. Independent variables were created using the same weight control and muscle-enhancing behaviors reported by nominated friends, and were used in logistic regression models to test associations between participants' and their friends' behaviors, stratified by gender. Results indicated that dieting, disordered eating and muscle-enhancing behaviors were common in this sample, and selected friends' behaviors were associated with the same behaviors in participants. For example, girls whose friends reported extreme weight control behaviors had significantly greater odds of using these behaviors than girls whose friends did not report these same behaviors (OR = 2.39). This research suggests that friends' weight- and shape-related behaviors are a feature of social relationships, and is the first report demonstrating these associations for muscle-enhancing behaviors. Capitalizing on the social element may be important to the development of increasingly effective intervention and prevention programs. Copyright © 2012 Elsevier Ltd. All rights reserved.

  1. The effects of receiving a rape disclosure: college friends' stories.

    Branch, Kathryn A; Richards, Tara N

    2013-05-01

    Research suggests that college women are at greater risk for rape and sexual assault than women in the general population or in a comparable age group. College women, away from home and family, may turn to friends for support. Friends may experience emotional reactions that affect their own functioning and may not feel they have anywhere to turn. In this study, we interviewed male and female college students who had received a rape disclosure from a friend. Their unique stories provide insight into the secondary effects of rape disclosure on friends. Implications of these findings for college campuses are discussed.

  12. Making Rice Production More Environmentally-Friendly

    Directory of Open Access Journals (Sweden)

    Norman Uphoff

    2016-05-01

    Full Text Available Irrigated rice production is one of the most essential agricultural activities for sustaining our global population, and at the same time, one of the agricultural sectors considered most eco-unfriendly. This is because it consumes a larger share of available freshwater resources, competing with varied ecosystems as well as other economic sectors; its paddy fields are responsible for significant emission of greenhouse gases; and the reliance on chemical fertilizers and various agrochemicals contributes to pollution of soils and water systems. These stresses on soils, hydrology and atmosphere are actually not necessary for rice production, which can be increased by modifying agronomic practices though more agroecologically-sound management practices. These, combined under the rubric of the System of Rice Intensification (SRI, can reduce requirements of irrigation water, chemical fertilizer and agrochemicals while increasing paddy yields and farmer’s net incomes. Here we discuss how irrigated rice production can be made more eco-friendly for the benefit of farmers, consumers and the environment. This is achieved by introducing practices that improve the growth and functioning of rice plants’ root systems and enhance the abundance, diversity and activity of beneficial soil organisms that live around plant roots and within the plants themselves as symbiotic endophytes.

    2017-05-01

    The landscape of breastfeeding has changed over the past several decades as more women initiate breastfeeding in the postpartum period and more hospitals are designated as Baby-Friendly Hospitals by following the evidence-based Ten Steps to Successful Breastfeeding. The number of births in such facilities has increased more than sixfold over the past decade. With more women breastfeeding and stays in the maternity facilities lasting only a few days, the vast majority of continued breastfeeding support occurs in the community. Pediatric care providers evaluate breastfeeding infants and their mothers in the office setting frequently during the first year of life. The office setting should be conducive to providing ongoing breastfeeding support. Likewise, the office practice should avoid creating barriers for breastfeeding mothers and families or unduly promoting infant formula. This clinical report aims to review practices shown to support breastfeeding that can be implemented in the outpatient setting, with the ultimate goal of increasing the duration of exclusive breastfeeding and the continuation of any breastfeeding.

    2002-01-01

    The dyestuff industry is suffering from the increases in costs of feedstock and energy for dye synthesis, and they are under increasing pressure to minimize the damage to the environment. The industries are continuously looking for cheaper, more environmentally friendly routes to existing dyes. The aim of this minireview is to discuss the most important advances in the fungal pigment area and its interest in biotechnological applications. Characteristic pigments are produced by a wide variety of fungi and the chemical composition of natural dyes are described. These pigments exhibit several biological activities besides cytotoxicity. The synthetic pigments authorized by the EC and in USA and the natural pigments available in the world market are discussed. The obstacle to the exploitation of new natural pigments sources is the food legislation, requesting costly toxicological research, manufacturing costs, and acceptance by consumers. The dislike for novel ingredients is likely to be the biggest impediment for expansion of the pigment list in the near future. If the necessary toxicological testing and the comparison with accepted pigments are made, the fungal pigments, could be acceptable by the current consumer. The potentiality of pigment production in Brazil is possible due to tremendous Amazonian region biodiversity.

  17. Bonobos protect and console friends and kin.

    Directory of Open Access Journals (Sweden)

    Elisabetta Palagi

    Full Text Available Post-conflict third-party affiliation has been reported to have different functional meanings, one of them being consolation. Here, we tested the main hypotheses that have been put forth to explain the presence of this phenomenon at a functional level in the bonobo: Self-Protection Hypothesis, Victim-Protection Hypothesis, Relationship-Repair or Substitute for Reconciliation Hypothesis, and Consolation Hypothesis. By analyzing the data collected over 10 years, we investigated what factors affected the distribution of both spontaneous third party affiliation (initiated by the bystander and solicited third party affiliation (initiated by the victim. We considered factors related to the individual features (sex, rank, age of victim and bystander, their relationship quality (kinship, affiliation, and the effect that third party affiliation had on the victim (such as protection against further attacks and anxiety reduction. Both spontaneous and solicited third party affiliation reduced the probability of further aggression by group members on the victim (Victim-Protection Hypothesis supported. Yet, only spontaneous affiliation reduced victim anxiety (measured via self-scratching, thus suggesting that the spontaneous gesture--more than the protection itself--works in calming the distressed subject. The victim may perceive the motivational autonomy of the bystander, who does not require an invitation to provide post-conflict affiliative contact. Moreover, spontaneous--but not solicited--third party affiliation was affected by the bond between consoler and victim, being the relationship between consoler and aggressor irrelevant to the phenomenon distribution (Consolation Hypothesis supported. Spontaneous affiliation followed the empathic gradient described for humans, being mostly offered to kin, then friends, then acquaintances. Overall, our findings do not only indicate the consolatory function of spontaneous third-party affiliation but they also

  18. Microbial 'old friends', immunoregulation and socioeconomic status.

    Science.gov (United States)

    Rook, G A W; Raison, C L; Lowry, C A

    2014-07-01

    The immune system evolved to require input from at least three sources that we collectively term the 'old friends': (i) the commensal microbiotas transmitted by mothers and other family members; (ii) organisms from the natural environment that modulate and diversify the commensal microbiotas; and (iii) the 'old' infections that could persist in small isolated hunter-gatherer groups as relatively harmless subclinical infections or carrier states. These categories of organism had to be tolerated and co-evolved roles in the development and regulation of the immune system. By contrast, the 'crowd infections' (such as childhood virus infections) evolved later, when urbanization led to large communities. They did not evolve immunoregulatory roles because they either killed the host or induced solid immunity, and could not persist in hunter-gatherer groups. Because the western lifestyle and medical practice deplete the 'old' infections (for example helminths), immunoregulatory disorders have increased, and the immune system has become more dependent upon microbiotas and the natural environment. However, urbanization maintains exposure to the crowd infections that lack immunoregulatory roles, while accelerating loss of exposure to the natural environment. This effect is most pronounced in individuals of low socioeconomic status (SES) who lack rural second homes and rural holidays. Interestingly, large epidemiological studies indicate that the health benefits of living close to green spaces are most pronounced for individuals of low SES. Here we discuss the immunoregulatory role of the natural environment, and how this may interact with, and modulate, the proinflammatory effects of psychosocial stressors in low SES individuals. © 2014 The Authors.

  19. Gratitude for help among adult friends and siblings.

    Rotkirch, Anna; Lyons, Minna; David-Barrett, Tamas; Jokela, Markus

    2014-07-06

    Although gratitude is a key prosocial emotion reinforcing reciprocal altruism, it has been largely ignored in the empirical literature. We examined feelings of gratitude and the importance of reciprocity in same-sex peer relations. Participants were 772 individuals (189 men; mean age = 28.80) who completed an online survey using a vignette design. We investigated (i) differences in reported gratitude and the importance of reciprocity among same-sex siblings and same-sex friends, and (ii) how relationship closeness moderates these associations. Based on the theory of kin altruism, we expect that people would feel more grateful towards friends than towards their siblings, and that lack of gratitude or failure to pay back a loan would bother more with friends than with siblings, irrespective of emotional closeness. Results showed that levels of gratitude and expectations of reciprocity were higher towards friends compared to siblings. This was the case also after controlling for emotional closeness. Being close generally made participants feel more grateful and expect lower displays of gratitude in the other. Closeness was also strongly associated with emotional gratitude among siblings compared to friends. We conclude that feelings and displays of gratitude have a special role in friendships. Although a close sibling may elicit as much gratitude as a friend does, even a very close friend is not exempt from the logic of reciprocity in the same way that a sibling is.

  1. Friends, family and social belonging as we age

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Aims: This study investigated if perceptions of social belonging in late adulthood are differentiated by the quality of family and friend relationships. Method:  The study consisted of two phases.  In Phase 1, 260 university staff and students, aged 18 to 75, completed an online survey investigating the quality of family and friend relationships and their association with social belonging.  In Phase 2, 88 older adults completed a refined print version of the survey.   Results:  Multiple regression was used to analyse the predictive ability of family and friend relationships on social belonging. In Phase 1, significant associations were found between both family and friend relationships and social belonging, with friendship yielding the strongest relationship.  Interestingly, in Phase 2 the association between quality of family and friend relationships and social belonging was mediated by age. Those aged 65 to 74 reported a significant relationship between friends and social belonging, which contrasted with those aged over 75.  A significant association between social belonging and family relationships was also found for the entire cohort aged over 65, while high quality friend relationships enhanced social belonging when family relationships were not strong. Conclusions: These results are tentative, but suggest that future research should consider the role that both friendships and family play in promoting social belonging in older adults.

    2011-01-01

    It is well-known that people lose friends after a stroke; what is less well understood is why this occurs. This study explored why people lose contact with their friends, and whether there are any protective factors. It also examined how friendship loss and change is perceived by the individual. Participants with a first stroke were recruited from one acute stroke unit in the UK. In-depth qualitative interviews took place between 8 and 15 months post stroke. 29 participants were recruited of whom 10 had aphasia. The main reasons given for losing friends were: loss of shared activities, reduced energy levels, physical disability, aphasia, unhelpful responses of others, environmental barriers, and changing social desires. The subset of participants who experienced the most extensive loss of friends were those who described a sense that they were 'closing in' on themselves leading to a withdrawal from social contact and a new preference for meeting only close friends and family. Those with aphasia experienced the most hurtful negative responses from others and found it more difficult to retain their friends unless they had strong supportive friendship patterns prior to the stroke. The factors which helped to protect friendships included: having a shared history, friends who showed concern, who lived locally, where the friendship was not activity-based, and where the participant had a 'friends-based' social network prior to the stroke. Given the link between depression and loss of friends post stroke, supporting an individual in maintaining a social network is likely to be beneficial. For intervention to be effective, however, it may need to take into account not only the impact of new physical and language disabilities, but also changing social desires. © 2011 Royal College of Speech & Language Therapists.

  3. Friends of friends: are indirect connections in social networks important to animal behaviour?

    2015-01-01

    Friend of a friend relationships, or the indirect connections between people, influence our health, well-being, financial success and reproductive output. As with humans, social behaviours in other animals often occur within a broad interconnected network of social ties. Yet studies of animal social behaviour tend to focus on associations between pairs of individuals. With the increase in popularity of social network analysis, researchers have started to look beyond the dyad to examine the role of indirect connections in animal societies. Here, I provide an overview of the new knowledge that has been uncovered by these studies. I focus on research that has addressed both the causes of social behaviours, i.e. the cognitive and genetic basis of indirect connections, as well as their consequences, i.e. the impact of indirect connections on social cohesion, information transfer, cultural practices and fitness. From these studies, it is apparent that indirect connections play an important role in animal behaviour, although future research is needed to clarify their contribution. PMID:25937639

    One of the crucial challenges of the aviation industry in upcoming years is to reduce emissions not only in the vicinity of airfields but also in cruise. Amongst other transport methods, airplanes emissions count for 3% of the CO 2 emissions. Initiatives to reduce this include not only investing in more fuel-efficient aircrafts or adapting existing ones to make them more efficient (e.g. by fitting fuel-saving winglets), but also more actively researching novel propulsion systems that incorporate environmentally friendly technologies. The Boeing Company through its European subsidiary, Boeing Research and Technology Europe (BR&TE) in collaboration with industry partners throughout Europe is working towards this goal by studying the possible application of advanced batteries and fuel-cell systems in aeronautical applications. One example is the development of a small manned two-seater prototype airplane powered only by proton exchange membrane (PEM) fuel-cell stacks, which runs on compressed hydrogen gas as fuel and pressurized air as oxidant, and Li-ion batteries. The efficient all composite motorglider is an all electric prototype airplane which does not produce any of the noxious engine exhaust by-products, such as carbon dioxide, carbon monoxide or NO x, that can contribute to climate change and adversely affect local air quality. Water and heat are the only exhaust products. The main objective is to demonstrate for the first time in aviation history a straight level manned flight with fuel-cells as the only power source. For this purpose, the original engine of a super Dimona HK36TTC glider from Diamond Aircraft Industries (Austria) was replaced by a hybrid power system, which feeds a brushless dc electrical motor that rotates a variable pitch propeller. Amongst the many technical challenges encountered when developing this test platform are maintaining the weight and balance of the aircraft, designing the thermal management system and the power management

    2014-02-01

    This cross-sectional study examined the relationship between a friend's level of internalizing distress and the focal child's perceptions of friendship amongst 5th, 8th, and 11th grade youth. Participants completed the Youth Self-Report to assess internalizing distress and measures assessing perceptions of friendship quality, social support, and self-disclosure within reciprocal, same-sex friendship dyads. Results indicated that youth with friends experiencing low levels of internalizing distress reported poorer friendship quality and decreased levels of social support and self-disclosure within the friendship compared to youth with friends experiencing average or high internalizing distress. In a second set of analyses controlling for the focal child's own internalizing symptoms, gender, and age, friend's level of internalizing distress remained a significant, unique predictor of target participants' self-disclosure about their own problems within the friendship. The findings suggest that a mild degree of internalizing distress may enhance, rather than harm, friendships amongst youth.

    This article investigates self-reported interventions by students in the alcohol, tobacco, illicit drug use, and drinking-driving of their friends. The data came from a study of 1184 students in Ontario schools in grades 7, 9, 11, and 13. We found that about a third of students intervened in friends' illegal drug use and drinking-driving but about half intervened about smoking. Students who intervened were more likely to be older and spend fewer nights at home. They were less likely to use cannabis, but had more friends using cannabis and illegal drugs. Also, they had more exposure to drug education and were more disapproving of drug use. Drug education may give students the knowledge and confidence to intervene in friends' drug use.

    Mitochondria are defining components of most eukaryotes. However, higher plant mitochondria differ biochemically, morphologically, and dynamically from those in other eukaryotes. FRIENDLY, a member of the CLUSTERED MITOCHONDRIA superfamily, is conserved among eukaryotes and is required for correct distribution of mitochondria within the cell. We sought to understand how disruption of FRIENDLY function in Arabidopsis (Arabidopsis thaliana) leads to mitochondrial clustering and the effects of this aberrant chondriome on cell and whole-plant physiology. We present evidence for a role of FRIENDLY in mediating intermitochondrial association, which is a necessary prelude to mitochondrial fusion. We demonstrate that disruption of mitochondrial association, motility, and chondriome structure in friendly affects mitochondrial quality control and leads to mitochondrial stress, cell death, and strong growth phenotypes. © 2014 American Society of Plant Biologists.

    We investigated whether losses of inhibitory control could be responsible for some friendly-fire incidents. Several factors are commonly cited to explain friendly-fire incidents, but failure of inhibitory control has not yet been explored. The Sustained Attention to Response Task (SART) could be a valid model for inhibition failures in some combat scenarios. Participants completed small-arms simulations using near infrared emitter guns, confronting research assistants acting as friends or foes. In Experiment 1, seven participants completed three conditions with three different proportions of foes (high, medium, low). In Experiment 2, 13 participants completed high-foe (high-go) and low-foe (low-go) versions of a small-arms simulation as well as comparative computer tasks. Participants made more friendly-fire errors (errors of commission) when foe proportion was high. A speed-accuracy trade-off was apparent, with participants who were faster to fire on foes also more likely to accidentally shoot friends. When foe proportion was higher, response times to foe stimuli were faster, and subjective workload ratings were higher. Failures of inhibitory control may be responsible for some friendly-fire incidents and the SART could be a suitable empirical model for some battlefield environments. The effect appears to be disproportionately greater at higher foe proportions. The exact nature of performance reductions associated with high-foe proportions requires further investigation. The SART may be a useful model of friendly-fire scenarios. It could be used to indicate a soldier's likelihood to commit a friendly-fire mistake and to identify high-risk environments. © 2015, Human Factors and Ergonomics Society.

    2014-01-01

    This article addresses the question of how creating an age-friendly city has come to be an important policy and planning issue in Portland, Oregon. In 2006, researchers from Portland State University's Institute on Aging examined the meanings of age friendliness among a broad range of participants in Portland, Oregon. The research was conducted in conjunction with the World Health Organization's (WHO) Age-Friendly Cities project and followed the completion of two earlier non-WHO-related projects. The city of Portland, through the Institute on Aging, was one of nine original members to apply for and be accepted into the WHO Global Network of Age-Friendly Cities and Communities. An Age-Friendly Portland Advisory Council was formed to guide the development of an action plan, monitor progress over time, and suggest additional research. To understand how Portland's age-friendly policy effort has developed over time, we use Kingdon's (1984) agenda-setting framework to explain how the policy problem was formulated, how solutions were developed, and the influence of local politics. The policy actors, including individuals and organizations working within and outside of government, are described. The Portland experience provides a case study that other cities, especially those with a strong commitment to community-engaged urban planning, may find useful as they develop age-friendly initiatives.

  2. Eco-friendly dentistry: Need of future. An overview

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available In today's world, it is very necessary to understand the importance of being eco-friendly in every facet of our lives. The color “green” has healing power and denotes renewal, growth, and hope. “Eco-friendly dentistry” attempts to reduce the detrimental impact of dental practices on the environment and promote environmental awareness and sustainability to patients. This paper attempts to cover all possible aspects of making a dental practice eco-friendly, both in a dental perspective as well as a general perspective. While establishing an eco-friendly dental workplace, the dentist needs to assess his choices in planning the infrastructure and purchasing of equipment and dental materials. Eco-friendly dentistry is a newly evolving practice of dentistry, which encompasses a simultaneous devotion to sustainability, prevention, precaution, and a minimally invasive patient-centric, as well as global-centric treatment. There are two main avenues for implementing eco-friendly dentistry: (1 appropriate policy development and implementation and (2 dentists taking responsibility/ownership in the absence of policies and regulations. Although in some cases, it may take a little extra effort or money; dentists throughout the world are doing their best to reduce the environmental impact of the dental practice. Although the commitment of one small dental office cannot save the planet, certainly, the collective efforts of many small offices as well as large dental hospitals/colleges can ensure that dentists, at least, will not be responsible for destroying it. This article discusses various factors that can be incorporated into dental practice that can help make dentistry eco-friendly.

  3. Global climate-friendly trade : Canada's chance to clean up

    International Nuclear Information System (INIS)

    Goldfarb, D.

    2010-03-01

    This paper discussed the global trade and investment in climate-friendly technologies, Canada's current position in this market, and the policy changes that are necessary for Canadian businesses to gain a stronger foothold in this sector. The global market for climate-friendly technologies is growing rapidly, but Canadian businesses have generally failed to exploit opportunities to export climate-friendly technologies and have generally lagged other countries in adopting such technologies developed elsewhere. Although Canadian businesses generally underperform in this sector, Canada does have notable strengths in 13 identified areas, including waste management technologies, energy technologies, and in parts of the value chains associated with wind and solar power. Targeting these areas of relative strength for further development could position Canada as a global leader in some climate-friendly technologies. For this to happen, Canadian governments need to establish clear policies, invest in research and development, and remove domestic and international barriers to the development and trade in climate-friendly technologies. 30 refs., 5 tabs., 5 figs.

    Portable, telemedicine-friendly devices offer novel opportunity for screening and monitoring glaucoma in the remote and rural regions of the world. This study examines the effective combination of telemedicine-friendly screening devices for detection of glaucoma in relation with conventional, hospital-based devices. A total of 399 eyes were screened with telemedicine-friendly devices and conventional, hospital-based devices such as ophthalmoscope, tonometer and perimeter. Combination of age and family history of glaucoma alone has a sensitivity of 35.6% (specificity 94.2%, area under the curve 0.81, correctly classified 81.1%) and an addition of telemedicine-friendly or conventional visual field tests optimized the sensitivity to 91.1% (specificity 93.6%, area under the curve 0.95, correctly classified 93%). Analysis indicates good agreement between vertical cup-to-disc ratio by ophthalmoscopy and digital image reading. An addition of intraocular pressure test does not change sensitivity (35.6%) and specificity (94.2%). This study indicates that evaluations of cup-to-disc ratio and visual field, using telemedicine-friendly devices, are most useful tools in screening for glaucoma. When used together these devices may be an alternative for conventional glaucoma screenings.

    The behavior and properties of associated bodies were studied through measurement of surface tension considering acetone-soluble fraction relatively light among various solvent extracts of coal. In experiment, the acetone-soluble fraction was extracted from the substances extracted from Upper Freeport coal as standard specimen using the mixed solvent of carbon disulfide (CS2) and N-methyl-2-pyrrolidinone (NMP), and it was dissolved into NMP after drying. Surface tension was measured by Wilhelmy method. The experimental results are as follows. Equilibrium surface tension is equal to the surface tension of pure solvent in a low concentration range of solution, and decreases with an increase in concentration approaching a fixed value at 0 in log concentration, nearly showing an S curve. Adsorption of species with non-polar aromatic ring of the acetone-soluble fraction on a solution surface probably decreases surface tension. Change with time in surface tension is observed which suggests fast initial reaction and slow subsequent reaction. 4 figs.

    Pilachowski, Catherine A.

    2012-01-01

    These days, most academic and research institutions recognize the importance of a family-friendly workplace, and have implemented at least some policies to support a sustainable work-life balance: family and medical leave, parental leave, stopping or extending tenure clocks, modified duty policies, breast feeding policies and lactation rooms, partner hiring programs, childcare programs, eldercare programs, emergency and sick child care programs, dependent care travel funds, etc. But while institutions may offer a menu of policies and free or low-cost services to support families, what's happening in your department? Achieving a supportive workplace culture requires that we dispel some of the myths associated with family-friendly policies, and establish that family-friendly policies not only benefit all employees, but also help the institution be more successful.

  9. That's What Friends Are For: Bystander Responses to Friends or Strangers at Risk for Party Rape Victimization.

    Katz, Jennifer; Pazienza, Rena; Olin, Rachel; Rich, Hillary

    2015-10-01

    The present research examined bystander responses to potential party rape scenarios involving either a friend or a stranger at risk. Undergraduate students (N = 151) imagined attending a party and seeing a man lead an intoxicated woman (friend or stranger) into a bedroom. After random assignment to conditions, participants reported on intentions to help, barriers to helping, victim blame, and empathic concern. As expected, based on their shared social group membership, bystanders intended to offer more help to friends than to strangers. Bystanders also reported more personal responsibility to help and more empathic concern when the potential victim was a friend rather than stranger. Observing a friend versus stranger at risk did not affect audience inhibition or perceived victim blame. Compared with women, men reported more blame and less empathic concern for potential victims. However, there were no gender differences in bystander intent to help or barriers to helping. In multivariate analyses, both responsibility to help and empathic concern for the potential victim uniquely predicted bystanders' intent to help a woman at risk for party rape. Results suggest that promoting social identification with peers at risk could increase bystander intervention. © The Author(s) 2014.

  10. When Do Friends Prevent Friends from Hooking Up Intoxicated? An Examination of Sex Differences and Hypothetical Intoxication in Peer Interventions.

    2017-08-01

    Despite the risks involved when mixing alcohol with casual sexual activity, the majority of college students engage in hookups, and the majority of those hookups involve alcohol. This study focused on the protective role college students' peers can play and the situational factors that might influence their willingness to intervene when a close friend is about to hook up intoxicated. Drawing on the theory of planned behavior (TPB), this study investigated differences in students' (N = 1270) attitudes, norms, perceived behavioral control, and intentions to persuade a close friend not to engage in a hypothetical drunken hookup using a 2 (friend sex) × 2 (participant sex) × 2 (sober/intoxicated) factorial design. Results indicated significant differences in the TPB variables. Participants intended to intervene with female friends, but not male friends, and women were more likely to intervene than men. Participants in the sober condition had stronger intentions to intervene than those in the intoxicated condition, but this effect was driven by increases in men's intentions when sober. Implications for theory and prevention programming are discussed.

  11. Achieving Child Friendly Justice through Child Friendly Methods: Let’s Start with the Right to Information

    Directory of Open Access Journals (Sweden)

    Helen Stalford

    2017-09-01

    Full Text Available Making the justice process ‘child friendly’ is a key priority for the children’s rights community. An abundance of commentary has been produced by the UN Committee on the Rights of the Child to highlight how justice proceedings can be made more accessible for children and, in 2010, the Council of Europe issued its comprehensive ‘Guidelines on Child Friendly Justice’. Despite these efforts, children remain ill-informed, not just about the nature of justice proceedings in which they may be implicated, but about the very existence and scope of their rights and how to enforce them. Despite unequivocal acknowledgement that the availability and accessibility of information is the crucial starting point in a children’s rights-based approach to dispensing justice, there has been surprisingly little attempt to scrutinise the availability, quality and accessibility of information about laws and policies affecting children. This article takes a closer look at what, exactly, ‘child friendly’ information means in practice. In doing so, we argue that attempts to develop child friendly information have yet to progress beyond adult-driven, largely tokenistic and superficial re-branding exercises. As such, efforts to develop child friendly resources are often of limited value in empowering young people to develop their legal literacy and realise their rights in practice. We reflect on our attempt to develop an explicitly children’s rights-based approach to the development of child friendly resources with a view to enhancing their purchase. This took place in the context of a pilot project, commissioned by the Council of Europe in June 2014, to create a child friendly version of their Child Friendly Justice Guidelines.

    Concern about the welfare of production animals is growing among various stakeholders, including the general public. Citizens can influence the market for premium welfare products by expressing public concerns, and consumers-the actors who actually purchase products-can do so through their purchasing behavior. However, current market shares for premium welfare products are small in Europe. To better align purchase behavior with public and individuals' concerns, insight is needed into determinants that influence the intention to purchase premium welfare products. A cross-sectional online survey of 787 Flemish milk consumers was conducted to investigate attitudes toward and intention to purchase animal-friendly milk. More than half of the sample (52.5%) expressed the intention to purchase animal-friendly milk. Linear regression modeling indicated that intention was positively influenced by (1) higher perceived product benefits from animal-friendly milk (milk with more health benefits and higher quality); (2) higher personal importance of extrinsic product attributes such as local production and country of origin; (3) higher personal importance of animal welfare; (4) a more natural living oriented attitude toward cows; and (5) a more positive general attitude toward milk. Intention was negatively influenced by (1) a stronger business-oriented attitude toward cows; and (2) by a higher personal importance attached to price. These insights in key components of purchase intention can assist producers, the dairy industry, and retailers to position and market animal-friendly milk.

    2013-01-01

    This two-study report identifies and validates a typology containing seven types of "friends with benefits relationships" (FWBRs). Study 1 asked heterosexual students to define the term FWBR and to describe their experience with the relationship type. Qualitative analysis of these data identified seven types of FWBRs (true friends, network opportunism, just sex, three types of transition in [successful, failed, and unintentional], and transition out). Study 2 quantitatively differentiates these relationship types in the amount of nonsexual interaction, strength of the friendship at the first sexual interaction, and history of romantic relationships with the FWBR partner (before the FWBR, after it, or both). Results from both studies clearly suggest that FWBRs represent a diverse set of relationship formulations where both the benefits (i.e., repeated sexual contact) and the friends (i.e., relationship between partners) vary widely. In many cases, FWBRs represent a desire for, or an attempt at, shifting the relationship from friends to a romantic partnership. Other implications are discussed, as are limitations and directions for future research. The diverse nature of FWBRs provides challenges for researchers that likely require multiple methods and theoretical frames.

  5. A Summary of Environmentally Friendly Turbine Design Concepts

    1999-07-01

    The Advanced Hydropower Turbine System Program (AHTS) was created in 1994 by the U.S. Department of Energy, Electric Power Research Institute, and the Hydropower Research Foundation. The Program’s main goal is to develop “environmentally friendly” hydropower turbines. The Program’s first accomplishment was the development of conceptual designs of new environmentally friendly turbines. In order to do so, two contractors were competitively selected. The ARL/NREC team of engineers and biologists provided a conceptual design for a new turbine runner*. The new runner has the potential to generate hydroelectricity at close to 90% efficiency. The Voith team produced new fish-friendly design criteria for Kaplan and Francis turbines that can be incorporated in units during rehabilitation projects or in new hydroelectric facilities**. These include the use of advanced plant operation, minimum gap runners, placement of wicket gates behind stay vanes, among others. The Voith team will also provide design criteria on aerating Francis turbines to increase dissolved oxygen content. Detailed reviews of the available literature on fish mortality studies, causation of injuries to fish, and available biological design criteria that would assist in the design of fish-friendly turbines were performed. This review identified a need for more biological studies in order to develop performance criteria to assist turbine manufacturers in designing a more fish-friendly turbine.

    The need to use environmentally friendly technologies throughout future space-related launch programs prompted a study aimed at replacing current petroleum and solvent-based Corrosion Preventive Compounds (CPCs) with environmentally friendly alternatives. The work in this paper focused on the identification and evaluation of environmentally friendly CPCs for use in protecting flight hardware and ground support equipment from atmospheric corrosion. CPCs are used as temporary protective coatings and must survive in the aggressive coastal marine environment that exists throughout the Kennedy Space Center, Florida. The different protection behaviors of fifteen different oily film CPCs, both common petroleum-based and newer environmentally friendly types, were evaluated on various steel and aluminum substrates. CPC and substrate systems were subjected to atmospheric testing at the Kennedy Space Center's Beachside Atmospheric Corrosion Test Site, as well as cyclic accelerated corrosion testing. Each CPC also underwent physical characterization and launch-related compatibility testing. The results for the fifteen CPC systems are presented in this paper.

    Communion among people is easily identifiable. Close friends or relatives frequently touch each other and this physical contact helps identifying the type of relationship they have. We tested whether a friendly touch and benefits elicit the emotion of gratitude given the close link between gratitude and communal relations. In Study 1, we induced a communal mindset and manipulated friendly touch (vs. non-touch) and benefit to female participants by a female confederate. We measured pre- and post-benefit gratitude, communal feelings, and liking toward the toucher, as well as general affect. In Study 2, we manipulated mindset, friendly touch and benefit, and measured the same variables in female pairs (confederate and participants). In both studies the results showed a main effect of touch on pre-benefit gratitude: participants who were touched by the confederate indicated more gratitude than those not touched. Moreover, benefit increased gratitude toward a confederate in the absence of touch, but not in the presence of touch. Additionally, perceiving the relationship as communal, and not merely liking the confederate, or a positive mood mediated the link between touch and gratitude. The results further support a causal model where touch increases communal feelings, which in turn increase gratitude at the end of the interaction, after having received a benefit from the interaction partner. These results support a broader definition of gratitude as an emotion embodied in communal relationship cues.

    Full Text Available Mother’s breast milk is the best product that the new born infant could be fed with. It contains nutritious matters necessary for growth and progress of the new born infants, ideally adapted for the baby. This is not only the food. It provides the support for protection against infections.The aim of the investigation was to establish whether the newborn condition right after the birth and anthropometric measures affect entering the baby friendly program. The study was conducted during 2003 in OGC CC Kragujevac and included 216 new born infants included in baby friendly program and 216 new born infants outside the program.The following parameters in newborn infants were observed: Apgar score, body mass, body length, head circumference.Significantly most often in both examined groups (73 up to 75%, the value of Apgar score of the new born infants was in the interval 9 – 10 and it did not affect the selection into baby friendly program.New born infants from baby friendly program statistically had significantly greater weight than the infants outside the program-on average for about 80 g. The greater weight positively affects entering the baby friendly program.Body length and infant head circumference did not statistically significantly differed between the examined groups.Statistically important difference in body mass can be justified by higher surveillance of pregnant women from the program. The treatment should reflect in controlled nourishment, avoidance of all harmful causes like consumption of cigarettes and alcoholic drinks, which are proven risks for the newborn infants from such pregnancies to have lesser body mass. The advantage of greater body mass lies in the fact that after the childbirth, the relative loss of the body weight is lesser compared to the infants outside the program.

    We use data from a population-based twin study to examine the association between characteristics of the friendship group and adolescents' own alcohol use at age 14, with focus on gender differences, both with respect to the adolescent's own gender and the gender composition of his/her friendship group. (1) We conducted analyses on the full epidemiological sample of individuals to determine the magnitude of association between friendship characteristics and alcohol use, and to test for interaction with gender and gender of friends. (2) We used the twin structure of the dataset to study the extent to which similarity in drinking behaviors between adolescents and their friends was due to shared genetic and/or environmental pathways. Friends' drinking, smoking, and delinquency were more strongly related to alcohol use in girls, compared to boys, and in adolescents with opposite-sex friends, compared to adolescents with only same-sex friends. Friends' alcohol use showed modest evidence of genetic influence in girls, suggesting peer selection; however, there was no evidence of genetic influence on friends' alcohol use in boys. The correlation between adolescent and friend drinking was largely attributable to shared environmental effects across genders. Gender and gender of friends moderate the associations between friends' behavior and adolescents' alcohol use, with evidence that girls, and those with opposite-sex friends, may be more susceptible to friends' influence. Genetically informative analyses suggest that similarity in alcohol use between adolescents and their friends is mediated, at least partially, through environmental pathways.

    dominant-looking leaders more than liberals. For the first time, we demonstrate that the effects of these contextual and individual differences are non-existent when subjects are asked to choose a friend instead of a leader: irrespective of ideology and context, people strongly prefer non-dominant friends...... these effects as evidence of a problem-sensitive and distinct psychology of followership. In two studies, we extend this research by demonstrating that preferences for physical traits in leaders' faces arise from an integration of both contextual and individual differences related to perceptions of social...... conflict and that these effects relate only to leader choices. Theoretically, we argue that increased preferences for facial dominance in leaders reflect increased needs for enforced coordinated action when one's group is seen to face threats from other coordinated groups rather than from random natural...

    This paper reports a novel environmentally friendly antibacterial cotton textile finished with reactive siloxane sulfopropylbetaine(SSPB). The results show that SSPB can be covalently bound onto the cotton textile surface, imparting perdurable antibacterial activity. The textiles finished with SSPB have been investigated systematically from the mechanical properties, thermal stability, hydrophilic properties and antibacterial properties. It is found that the hydrophilicity and breaking strength are improved greatly after the cotton textiles are finished with SSPB. Additionally, the cotton textiles finished with SSPB exhibit good antibacterial activities against gram-positive bacteria Staphylococcus aureus (S.aureus, ATCC 6538), gram-negative bacteria Escherichia coli (E.coli, 8099) and fungi Candida albicans (C.albicans, ATCC 10231). Moreover, SSPB is nonleachable from the textiles, and it does not induce skin stimulation and is nontoxic to animals. Thus, SSPB is ideal candidate for environmentally friendly antibacterial textile applications. © 2011 American Chemical Society

    Research efforts are under way to replace current corrosion inhibitors with more environmentally friendly alternatives. However, problems with corrosion inhibition efficiency, coating compatibility and solubility have hindered the use of many of these materials as simple pigment additives.This paper will present technical details on how the Corrosion Technology Lab at NASAs Kennedy Space Center (KSC) has addressed these issues by encapsulating environmentally friendly inhibitors into organic and inorganic microparticles and microcapsules. The synthetic process for polymer particles was characterized and post-synthesis analysis was performed to determine the interactions between the inhibitors and the encapsulation material. The pH-controlled release of inhibitors from various particle formulations in aqueous base was monitored and compared to both electrochemical and salt immersion accelerated corrosion experiment. Furthermore, synergistic corrosion inhibition effects observed during the corrosion testing of several inhibitor combinations will be presented.

  12. Academic Achievement and Its Impact on Friend Dynamics.

    Flashman, Jennifer

    2012-01-01

    Academic achievement in adolescence is a key determinant of future educational and occupational success. Friends play an important role in the educational process. They provide support and resources and can both encourage and discourage academic achievement. As a result, the friends adolescents make may help to maintain and exacerbate inequality if friends are sorted on the basis of academic achievement. These observations prompt the question: How does academic achievement affect the friendship ties made? Using data from the high schools in the Add Health saturated sample, the author models network change using a stochastic actor-based Markov model for the co-evolution of networks and behavior. This model is carried out at the school level for each of the high schools included in the saturated sample. Results show that in the most typical American schools, similarity in academic achievement is an important and consistent predictor of friendship ties in a dynamic context. High-achieving students are more likely to extend ties to other high-achieving students, net of other sociodemographic, network, and proximity characteristics, while low-achieving students are more likely to extend ties to other low-achieving students. Adolescents respond to changes in academic achievement by changing their friendship ties.

    Breastfeeding is widely viewed as the optimal feeding method for infants among professional nursing and medical organizations. Its health benefits have been comprehensively studied and documented for both infants and mothers. Hospitals and birthing centers can strongly influence the outcomes for mothers who choose to breastfeed by establishing effective breastfeeding behaviors immediately after birth and during the hospital stay. The Baby-Friendly USA initiative outlines 10 steps to successful breastfeeding. Although these steps have been successfully supported in practice, they can be difficult to implement due to a variety of factors, including resistance to change. Specific steps generate more barriers to overcome than others--namely exclusive breastfeeding without supplementation or pacifiers, rooming-in for 23 out of 24 hours, and skin-to-skin contact with a parent immediately after birth and during the hospital stay. Our hospital spent 5 years implementing Baby-Friendly practices to prepare for a successful site visit. In the process, barriers to key Baby-Friendly steps were overcome through creative approaches and strategic education for staff, physicians, and parents. The purpose of this article is to outline specific actions taken that assisted our hospital in its successful journey. Those actions and strategies will hopefully be of value to others in their journey toward designation.

    To evaluate whether the risk of DSM-III major depressive disorder (MDD) is uniform across the 6 months after adolescent exposure to a friend's suicide, and to examine potential moderating or mediating processes that may influence the risk of new-onset MDD. One-month incidence rates of MDD were compared between 129 adolescents who were exposed to a friend's suicide between December 1988 and March 1991 and 145 similar-aged, unexposed community controls participating in the Youth Exposed to Suicide study. Clinical, family, and social factors that antedated the exposure were examined as predictors of new-onset MDD within 1 month of the suicide. Exposed adolescents had a markedly increased risk of developing new-onset MDD that was restricted to a narrow period of time, within 1 month after exposure. In contrast, there were no differences in the incidence of MDD between the groups in months 2 to 6. Past history of alcohol abuse increased the risk of exposure to suicide, which subsequently increased the risk of new-onset MDD within 1 month of exposure. Exposed youths who had both a family history of MDD and feelings of accountability for the death were at considerably increased risk of new-onset MDD. For adolescents exposed to a friend's suicide, events surrounding the death interact with family history of MDD to greatly increase the risk for new-onset MDD.

    2016-05-01

    We present an introduction to the patented OS Friendly Microprocessor Architecture (OSFA) and hardware level computer security. Conventional microprocessors have not tried to balance hardware performance and OS performance at the same time. Conventional microprocessors have depended on the Operating System for computer security and information assurance. The goal of the OS Friendly Architecture is to provide a high performance and secure microprocessor and OS system. We are interested in cyber security, information technology (IT), and SCADA control professionals reviewing the hardware level security features. The OS Friendly Architecture is a switched set of cache memory banks in a pipeline configuration. For light-weight threads, the memory pipeline configuration provides near instantaneous context switching times. The pipelining and parallelism provided by the cache memory pipeline provides for background cache read and write operations while the microprocessor's execution pipeline is running instructions. The cache bank selection controllers provide arbitration to prevent the memory pipeline and microprocessor's execution pipeline from accessing the same cache bank at the same time. This separation allows the cache memory pages to transfer to and from level 1 (L1) caching while the microprocessor pipeline is executing instructions. Computer security operations are implemented in hardware. By extending Unix file permissions bits to each cache memory bank and memory address, the OSFA provides hardware level computer security.

    This study tests the hypothesis that adolescents with romantic partners are less similar to their friends on rates of alcohol abuse than adolescents without romantic partners. Participants (662 girls, 574 boys) ranging in age from 12 to 19 years nominated friends and romantic partners, and completed a measure of alcohol abuse. In hierarchical linear models, friends with romantic partners were less similar on rates of alcohol abuse than friends without romantic partners, especially if they were older and less accepted. Follow-up longitudinal analyses were conducted on a subsample (266 boys, 374 girls) of adolescents who reported friendships that were stable across 2 consecutive years. Associations between friend reports of alcohol abuse declined after adolescents became involved in a romantic relationship, to the point at which they became more similar to their romantic partners than to their friends.

    2012-12-01

    Full Text Available Social norms govern what is considered an acceptable show of emotions as a function of social circumstances. Yet, very little empirical work has been done on how the nature of a relationship influences reactions to faked emotions. Faking emotions has primarily been discussed in the context of service encounters. Popular theories encourage authenticity in a relationship. Our purpose was to examine the possibility that under certain conditions, people prefer their relationship partners to fake their emotions. We studied partners' preferences with best friends and with colleagues as regards their counterparts’ expression of authentic anger. Our results showed that people preferred their colleagues not to express their anger, and to fake their emotions to a significantly greater extent than their best friends. In exchanges between colleagues, individuals preferred their partners to fake their emotions more in situations of high intensity anger than in situations of low intensity anger.

    The number of factories and home industries, both upper and lower middle class certainly adds waste generated, resulting in environmental pollution. The development of buildings is one of the largest contributors to global warming. For that, it takes technological innovations that lead to the criteria of green building. The application of green material is important aspects of environmentally friendly development, the selection of materials on the green material criteria of both roles should be applied continuously in order to realize the environmental sustainability of the material. Utilization Waste eggshell and bagasse which is a community waste, has the potential to become innovative environmentally friendly building materials. The eggshell is composed of 94% calcium carbonate, 1% magnesium carbonate, 1% calcium phosphate, and 4% organic material, especially protein, while the bagasse has a high content of silica (SiO2). In this study, the compounds are used as raw material for making alternative drywall in the form of DECO FRECASE. DECO FRECASE is an innovation of environmentally friendly building materials as an interior wall construction. Through DECO FRECASE, it is expected that building material innovation in Indonesia can be improved and of course environmental problems can be minimized by utilizing it as raw material for building construction.

    The family, and parents in particular, are considered the most important influencers regarding children's energy-balance related behaviours (EBRBs). When children become older and gain more behavioural autonomy regarding different behaviours, the parental influences may become less important and peer influences may gain importance. Therefore the current study aims to investigate simultaneous and interactive associations of family rules, parent and friend norms and modelling with soft drink intake, TV viewing, daily breakfast consumption and sport participation among schoolchildren across Europe. A school-based cross-sectional survey in eight countries across Europe among 10-12 year old schoolchildren. Child questionnaires were used to assess EBRBs (soft drink intake, TV viewing, breakfast consumption, sport participation), and potential determinants of these behaviours as perceived by the child, including family rules, parental and friend norms and modelling. Linear and logistic regression analyses (n = 7811) were applied to study the association of parental (norms, modelling and rules) and friend influences (norm and modelling) with the EBRBs. In addition, potential moderating effects of parental influences on the associations of friend influences with the EBRBs were studied by including interaction terms. Children reported more unfavourable friend norms and modelling regarding soft drink intake and TV viewing, while they reported more favourable friend and parental norms and modelling for breakfast consumption and physical activity. Perceived friend and parental norms and modelling were significantly positively associated with soft drink intake, breakfast consumption, physical activity (only modelling) and TV time. Across the different behaviours, ten significant interactions between parental and friend influencing variables were found and suggested a weaker association of friend norms and modelling when rules were in place.

    This study examined the correlates of objective social isolation from extended family members and friends among older adults. The analysis is based on the older adult sub-sample of the National Survey of American Life (n = 1321). Multinomial logistic regression analyses examined race/ethnicity, demographics, functional health and family and friend network factors as correlates of objective isolation from family and friends. Only 4.47% of respondents were objectively isolated from both their extended family and friends, 10.82% were isolated from their friends, and 7.43% were isolated from their family members. Men were more likely to be objectively isolated from both family and friends and older adults who live with others were significantly more likely to be objectively isolated from their friends. When controlling for subjective social isolation, the two measures of functional health were significantly associated with objective social isolation. In particular, higher levels of self-care impairment decreased the risk of being objectively isolated from friends only, whereas higher mobility impairment was associated with an increased likelihood of being objectively isolated from friends only. Subjective evaluations of social isolation from family and friends were consistently associated with being objectively isolated from family and friends. There were no significant differences between African-Americans, Black Caribbeans and non-Hispanic Whites in objective isolation. These and other findings are discussed in detail. PMID:29510504

    Skipping meals is particularly common during adolescence and can have a detrimental effect on multiple aspects of adolescent health. Understanding the correlates of meal-skipping behaviours is important for the design of nutrition interventions. The present study examined maternal and best friends' influences on adolescent meal-skipping behaviours. Frequency of skipping breakfast, lunch and dinner was assessed using a Web-based survey completed by 3001 adolescent boys and girls from years 7 and 9 of secondary schools in Victoria, Australia. Perceived best friend and maternal meal skipping, modelling of healthy eating (eating healthy food, limiting junk food, eating fruit and vegetables) and weight watching were assessed. Best friend and maternal factors were differentially associated with meal-skipping behaviours. For example, boys and girls who perceived that their best friend often skipped meals were more likely to skip lunch (OR = 2·01, 95 % CI 1·33, 3·04 and OR = 1·93, 95 % CI 1·41, 2·65; P < 0·001). Boys and girls who perceived that their mother often skipped meals were more likely to skip breakfast (OR = 1·48, 95 % CI 1·01, 2·15; P < 0·05 and OR = 1·93, 95 % CI 1·42, 2·59; P < 0·001) and lunch (OR = 2·05, 95 % CI 1·35, 3·12 and OR = 2·02, 95 % CI 1·43, 2·86; P < 0·001). Educating adolescents on how to assess and interpret unhealthy eating behaviours that they observe from significant others may be one nutrition promotion strategy to reduce meal-skipping behaviour. The involvement of mothers may be particularly important in such efforts. Encouraging a peer subculture that promotes regular consumption of meals and educates adolescents on the detrimental impact of meal-skipping behaviour on health may also offer a promising nutrition promotion strategy.

    2014-09-01

    Adolescence is marked by complex physical, cognitive, social, and emotional development, which can be stressful for families and adolescents. Before the onset of puberty, providers should clearly lay the groundwork for clinical care and office visits during the adolescent years. This article addresses the guidelines and current legal standards for confidentiality in adolescent care, the most frequently used psychosocial screening tools, and current recommendations for preventive health services and immunizations. Through the creation of teen-friendly clinics, primary care providers are well positioned to offer guidance and support to teens and their parents during this time of transition and growth.

    2016-06-01

    Recognition that the live yellow fever vaccine may rarely be associated with viscerotropic disease (YEL-AVD) has diminished its safety status. However, the vaccine remains the principal tool for limiting the occurrence of yellow fever, making large portions of Africa and South America more habitable. The subject has previously been exhaustively reviewed. Novel concepts in the current report include the description of a systematic method for deciding whom to vaccinate, recommendations for obtaining data helpful in making that decision, and suggestions for additional study. The vaccine is indeed a worthy friend, but its adverse reactions need to be recognized.

    The purpose of this study was to assess rural North Dakota adolescents' experiences in accessing adolescent-friendly health services and to examine the relationship between rural adolescents' communication with health care providers and risk behaviors. Data are from the Rural Adolescent Health Survey (RAHS), an anonymous survey of 14- to 19-year-olds (n = 322) attending secondary schools in four frontier counties of North Dakota. Descriptive statistics were used to assess participants' access to adolescent-friendly health services characterized as accessible, acceptable, and appropriate. Logistic regressions were used to examine whether participant-reported risk behaviors predicted communication with health care providers about individual health risk behaviors. Rural adolescents reported high access to acceptable primary health care services but low levels of effective health care services. Participant report of engaging in high-risk behaviors was associated with having received information from health care providers about the leading causes of morbidity and mortality. These findings reveal missed opportunities for primary care providers in rural settings to provide fundamental health promotion to adolescents.

    Fly ash (FA) and Alccofine are the eco-friendly materials that can be used in the production of concrete composites. Initially, concrete mixes of M30 grade with replacement of cement by 0%, 5%, 10%, 15%, 20% and 25% by weight of Fly ash were prepared. They were subjected to compression test so as to select the optimum replacement percentage of FA. Keeping this optimum percentage of FA as constant, additional replacement of cement with Alccofine was done varying its replacement in the range of 8%, 10%, 12% and 14%. The mechanical properties such as compressive, split tensile and flexural strengths of these mixes were computed for 7, 14 and 28 days. The results of Eco-Friendly Concrete (EFC) are compared with those of control concrete. It was observed that EFC mixes exhibited superior qualities like quick setting and enhanced workability, their mechanical properties were found to be higher than that of the conventional concrete. This goes to prove that the combination of FA and Alccofine together as replacement for cement would enhance the properties of EFC.

    De Boer, Solke H; López, María M

    2012-01-01

    Accurate plant disease diagnoses and rapid detection and identification of plant pathogens are of utmost importance for controlling plant diseases and mitigating the economic losses they incur. Technological advances have increasingly simplified the tools available for the identification of pathogens to the extent that, in some cases, this can be done directly by growers and producers themselves. Commercially available immunoprinting kits and lateral flow devices (LFDs) for detection of selected plant pathogens are among the first tools of what can be considered grower-friendly pathogen monitoring methods. Research efforts, spurned on by point-of-care needs in the medical field, are paving the way for the further development of on-the-spot diagnostics and multiplex technologies in plant pathology. Grower-friendly methods need to be practical, robust, readily available, and cost-effective. Such methods are not restricted to on-the-spot testing but extend to laboratory services, which are sometimes more practicable for growers, extension agents, regulators, and other users of diagnostic tests.

    Each stage of the human life course is characterised by a distinctive pattern of social relations. We study how the intensity and importance of the closest social contacts vary across the life course, using a large database of mobile communication from a European country. We first determine the most likely social relationship type from these mobile phone records by relating the age and gender of the caller and recipient to the frequency, length, and direction of calls. We then show how communication patterns between parents and children, romantic partner, and friends vary across the six main stages of the adult family life course. Young adulthood is dominated by a gradual shift of call activity from parents to close friends, and then to a romantic partner, culminating in the period of early family formation during which the focus is on the romantic partner. During middle adulthood call patterns suggest a high dependence on the parents of the ego, who, presumably often provide alloparental care, while at this stage female same-gender friendship also peaks. During post-reproductive adulthood, individuals and especially women balance close social contacts among three generations. The age of grandparenthood brings the children entering adulthood and family formation into the focus, and is associated with a realignment of close social contacts especially among women, while the old age is dominated by dependence on their children.

    Full Text Available In the Italian market, voluntary certifications implying higher levels of animal welfare generally fall into wider production schemes. Despite of the results of EU surveys indicating that about 50% of Italian consumers can easily identify and find animal-friendly products, they still are distributed scarcely or discontinuously in the main retail chains. To assess the apparent contradiction between the intricate information consumers receive from labels and their declared awareness about animal welfare, a survey was conducted in Emilia Romagna region on 355 Italian consumers (face-to-face interviews based on a structured, semi-close-ended questionnaire. Overall, consumers showed a low degree of knowledge about animal welfare attributes, animal farming conditions and animal protection policies (about 30% of correct answers, and a low level of awareness of the effects of their purchasing choices on the welfare of farmed animals (22%. The respondents also showed difficulties in identifying animal-friendly products and often confused them with other certified foods, having sometimes a weak connection (or none at all to animal welfare (e.g., Protected Designation of Origin products. However, most consumers declared to be ready to pay a premium price in name of animal welfare. In conclusion, a labelling system for the welfare content of animal-derived foods is confirmed to be an effective strategy to compensate the efforts of farmers in improving animal welfare, provided that the information given is clear and able to fill the substantial lack of consumer knowledge.

    Developing various approaches for preparing high performance materials has long been topics and tasks both for scientists and for engineers. Despite that many methods have been developed for preparing nanomaterials, developing simple and environment-friendly ways for preparing nanomaterials is very attractive. Here a simple approach of synthesizing Fe3O4 nanoparticles by arc-discharge submerging in water was reported. The results showed that by this method Fe3O4 nanoparticles can be synthesized at large scale. The as-prepared Fe3O4 nanoparticles exhibited uniform spherical shape and their diameters varied with arc-discharging parameters. The experimental results showed that the size of the synthesized Fe3O4 nanoparticles can be controlled through adjusting the processing parameters. Since no vacuum system has been used, the synthesizing process is greatly simplified. In addition, only cheap deionized water and industrial iron bar are used and no pollution or harmful byproducts are found in the synthesis process. It indicated that the present approach is a simple, low-cost and environment-friendly one for preparing nanoparticles.

    Historical assessments of combat fratricide reveal principal contributing factors in the effects of stress, degradation of skills due to continuous operations or sleep deprivation, poor situation awareness, and lack of training and discipline in offensive/defense response selection. While these problems are typically addressed in R&D focusing on traditional ground-based combat, there is also an emerging need for improving situation awareness and decision making on defensive/offensive response options in the cyber defense arena, where a mistaken response to an actual or perceived cyber attack could lead to destruction or compromise of friendly cyber assets. The purpose of this report is to examine cognitive factors that may affect cyber situation awareness and describe possible research needs to reduce the likelihood and effects of "friendly cyber fire" on cyber defenses, information infrastructures, and data. The approach is to examine concepts and methods that have been described in research applied to the more traditional problem of mitigating the occurrence of combat identification and fratricide. Application domains of interest include cyber security defense against external or internal (insider) threats.

    The NASA Kennedy Space Center's Corrosion Technology Lab at the Kennedy Space Center in Florida, U.S.A. has been developing multifunctional smart coatings based on the microencapsulation of environmentally friendly corrosion indicators, inhibitors and self-healing agents. This allows the incorporation of autonomous corrosion control functionalities, such as corrosion detection and inhibition as well as the self-healing of mechanical damage, into coatings. This paper presents technical details on the characterization of inhibitor-containing particles and their corrosion inhibitive effects using electrochemical and mass loss methods. Three organic environmentally friendly corrosion inhibitors were encapsulated in organic microparticles that are compatible with desired coatings. The release of the inhibitors from the microparticles in basic solution was studied. Fast release, for immediate corrosion protection, as well as long-term release for continued protection, was observed. The inhibition efficacy of the inhibitors, incorporated directly and in microparticles, on carbon steel was evaluated. Polarization curves and mass loss measurements showed that, in the case of 2MBT, its corrosion inhibition effectiveness was greater when it was delivered from microparticles.

    Friendships play a major role in cognitive, emotional and social development in middle childhood. We employed the online Cyberball social exclusion paradigm to understand the neural correlates of dyadic social exclusion among best friends assessed simultaneously. Each child played with their friend and an unfamiliar player. Event-related potentials (ERPs) were assessed via electroencephalogram during exclusion by friend and unfamiliar peer. Data were analyzed with hierarchical linear modeling to account for nesting of children within friendship dyads. Results showed that stranger rejection was associated with larger P2 and positive slow wave ERP responses compared to exclusion by a friend. Psychological distress differentially moderated the effects of friend and stranger exclusion such that children with greater psychological distress were observed to have larger neural responses (larger P2 and slow wave) to exclusion by a stranger compared to exclusion by a friend. Conversely, children with lower levels of psychological distress had larger neural responses for exclusion by a friend than by a stranger. Psychological distress within the dyad differentially predicted the P2 and slow wave response. Findings highlight the prominent, but differential role of individual and dyadic psychological distress levels in moderating responses to social exclusion in middle childhood. © The Author (2016).

    The purpose of this study was to assess dieting behavior, the number of friends who diet, and number of friends who pressure to go on a diet among a sample of 2,519 Thai adolescents. More than half of the girls (52.2%) and over one-fourth of boys (28.0%) reported going on a diet in the past 30 days. Dieting among friends was very common with only 14.2% of girls and 34.3% of boys saying none of their friends dieted. Results also showed significant associations between 1) number of friends who diet and 2) number of friends who pressure to diet with dieting behavior, body mass index (BMI), weight satisfaction, perceived body fatness, effort to look like people in the media, and frequency of thinking about wanting to be thinner in girls. In addition, several of these associations for boys were significant. The role of BMI in these relationships was also explored.

    2013-01-01

    We examined evidence for friendship influences on children's physical activity (PA) through systematic searches of online databases in May 2012. We identified 106 studies (25 qualitative) published in English since 2000 that analyzed indicators of friendship influences (e.g., communication about PA, friends’ PA, and PA with friends) among persons younger than 19 years. Children's PA was positively associated with encouragement from friends (43 of 55 studies indicating a positive relationship), friends' own PA (30/35), and engagement with friends in PA (9/10). These findings are consistent with friends influencing PA, but most studies did not isolate influence from other factors that could explain similarity. Understanding friendship influences in childhood can facilitate the promotion of lifelong healthy habits. PA with friends should be considered in health promotion programs. PMID:23678914

    This narrative study examined the process of personal storytelling between college-age friends who were similarly introverted or extraverted. Participants were 19 introverted and 20 extraverted same-sex pairs (49 percent female) who had been friends for an average of 18 months. Stories emerged spontaneously during 10-minute catch-up conversations. Extraverted friends more often told stories that changed the topic, and more often co-constructed story plots. Introverted friends more often told stories that were embedded in a developing theme, and constructed story plots solo. With regard to content, extraverted friends told stories about romance more so than introverted friends, whose stories more often concerned family/hometown, and older events. The findings suggest that the traits of extraversion and introversion channel the identity-making process. PMID:19325709

    Previous research has indicated that friends' drinking may influence alcohol use in adolescents and young adults. We explored whether similarities in the drinking behavior of friends of twins influence the genetic architecture of alcohol use in adolescence and young adulthood. Survey data from The Netherlands Twin Register were available for 1,526 twin pairs aged 16-25 years. We categorized the twin pairs as concordant (both report similar alcohol use in their friends) or discordant for the alcohol use of their friends. Genetic moderator models were tested by carrying out multi-group analyzes in Mplus. Findings showed a significant moderation effect. Genetic factors were more and common environment less important in the explanation of variation in alcohol use in twins discordant for alcohol use of friends than in twins concordant for alcohol use of friends.

    : The Baby-Friendly Hospital Initiative (BFHI) is a program developed by the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) to promote breastfeeding in hospitals and birthing facilities worldwide. Since the program was launched in 1991, breastfeeding initiation, duration, and exclusivity have increased globally, a trend largely attributed to changes in hospital policies and practices brought about by the BFHI. This article provides an overview of these practices and policies, the institutional benefits of achieving BFHI certification, and the process through which health care facilities can do so. All nurses-whether they work in maternity care or another nursing specialty in a hospital, ambulatory, or community setting-can play a role in promoting societal health through their support of long-term breastfeeding as recommended by the WHO and UNICEF.

    These days it seems that what chemistry needs more than anything else is a good p.r. agent. If you ask John or Joan Q. Public about the accomplishments of the chemical industry, chances are they'll mention Love Canal, CFCs destroying the ozone layer, or carcinogens in food. However, if the national meeting of the American Chemical Society in Washington, D.C., 2 weeks ago is any indication, chemists are working hard to fix the image problem. Nearly all of the two dozen press conferences held during the meeting focused on food, health topics, environment-friendly technology, or some other subject close to consumers' hearts. And the scientific talks themselves reflected the same interests, with sessions such as 'Environmental Successes in the Chemical Industry', 'Food Phytochemicals for Cancer Prevention', 'Chemistry of Electrophilic Metal Complexes', 'New Advances in Polyolefin Polymers', 'Zapping acid rain with microwaves.'

    Quantity of waste toner cartridges has been generated following the increasing demand for printer and duplicator. Waste toner cartridge contains abundant valuable metals, plastics as well as toxic residual toner. Therefore, the recovery of waste toner cartridges is a meaningful subject, not only from waste treatment but also from environment protection. This study proposed a mechanical production line for recovering waste toner cartridges. The recovery process involved shearing process, magnetic separation, and eddy current separation. The recovery rates of steel (magnet), toner, aluminum, and plastic were 98.4%, 95%, 97.5%, and 98.8%, respectively. The results of the comparison between the production line and full manual dismantling indicated that the production line succeed in recovering waste toner cartridges. In addition, the proposed production line is an efficient and environmental friendly way for recovering waste toner cartridges. Copyright © 2010 Elsevier B.V. All rights reserved.

    2011-12-01

    The manned mission to Mars is expected to last almost three years. A human factor must be taken seriously into account in such a long-term mission. A big comfortable habitat can help to overcome sociopsychological problems, that occur in ICEs (Isolated and Confined Environments). Authors have come forward to this issue and have developed a Martian base design as a human friendly habitat. The project is based on researches of extreme conditions on Mars, architecture in ICEs and contemporary building technologies. The base consists of five modules: a Central Module (CM), an Agriculture Dome (AD), a Residential Dome (RD), a Laboratory Dome (LD) and a Garage (G). Each element has its own functional purpose. The CM is a metal capsule similar to the Reference Mission module (RM, NASA, 1997). Domes are inflatable multilayer structures, which interiors are "open planned". Interiors can be arranged and divided into rooms by using modular partition walls designed by authors.

    Full Text Available Oil from J. multifida was extracted and it was first converted into N,N-bis(2-hydroxyethyl Jatropha fatty amide (HEJFA. HEJFA has been synthesized by reaction between Jatropha oil and diethanol amine in presence of zinc oxide as a catalyst. The reaction is relatively rapid and proceeded to high yield at 200±5 OC. The resulting HEJFA was used to formulate thermosetting coating compositions. Films were cured at ambient (air drying and elevated (stove drying temperatures using N, N-bis(2-hydroxyethyl Jatropha fatty amide (HEJFA as eco-friendly crosslinking agent for acrylic resin. The coating performance of the various compositions was tested by measurement of scratch hardness, impact strength and chemical resistance. The results show better performance of the HEJFA based compositions compared to butylated melamine formaldehyde (MF based compositions.

    Natural-based polyelectrolytes (PELs), with all the advantages coming from being produced from renewable and biodegradable sources, are a potential solution for the removal of dyes from wastewater. In this work, surplus Eucalyptus bleached cellulose fibres from a paper mill were modified to increase the charge and solubility of cellulose. First, reactive aldehyde groups were introduced in the cellulose backbone by periodate oxidation of cellulose. Further modification with alkylammonium produced positively charged cellulose-based PELs. The final products were characterized by several analytical techniques. The PEL with the highest substitution degree of cationic groups was evaluated for its performance in decolouration processes, bentonite being used as aid. This was found to be effective for colour removal of either anionic or cationic dyes. Bio-PELs can thus be considered as very favourable eco-friendly flocculation agents for decolouration of harsh effluents from several industries, considering their biodegradable nature and thus the ability to produce less sludge.

    Rapidly dividing and invasive cancer cells are strongly dependent on effective lysosomal function. Accordingly, transformation and cancer progression are characterized by dramatic changes in lysosomal volume, composition and cellular distribution. Depending on one's point of view, the cancer-associated changes in the lysosomal compartment can be regarded as friends or foes. Most of them are clearly transforming as they promote invasive growth, angiogenesis and drug resistance. The same changes can, however, strongly sensitize cells to lysosomal membrane permeabilization and thereby to lysosome-targeting anti-cancer drugs. In this review we compile our current knowledge on cancer-associated changes in lysosomal composition and discuss the consequences of these alterations to cancer progression and the possibilities they can bring to cancer therapy.

    These days it seems that what chemistry needs more than anything else is a good p.r. agent. If you ask John or Joan Q. Public about the accomplishments of the chemical industry, chances are they'll mention Love Canal, CFCs destroying the ozone layer, or carcinogens in food. However, if the national meeting of the American Chemical Society in Washington, D.C., 2 weeks ago is any indication, chemists are working hard to fix the image problem. Nearly all of the two dozen press conferences held during the meeting focused on food, health topics, environment-friendly technology, or some other subject close to consumers' hearts. And the scientific talks themselves reflected the same interests, with sessions such as Environmental Successes in the Chemical Industry', Food Phytochemicals for Cancer Prevention', Chemistry of Electrophilic Metal Complexes', New Advances in Polyolefin Polymers', Zapping acid rain with microwaves.'

    Biomineralization is a natural process aided by living organisms. Due to its applicability in ground improvement and bioremediation, Microbially Induced Calcite Precipitation (MICP) is an interdisciplinary field of study combining engineering, chemistry and microbiology. Bioremediation has been applied widely for contamination containment or removal, in this case it will be containment. MICP can also be applied to improve the efficiency of insitu bioremediation. Urease is an enzyme which can facilitate increased calcite precipitation. However the production of urease by bacteria and thus the resulting carbonate precipitation are inhibited by environmental factors including calcium concentration, bacterial concentration, pH and temperature. Under good conditions MICP can be used for heavy metal and radionuclide immobilization. However technologies such as bioconsolidation and biocementation require improvement such as time and cost. This paper highlights the application of MICP in addition to suggested improvements to make it more eco-friendly and sustainable.

    2008-01-01

    Main base ingredients of lip balm such as petroleum jelly and coloring materials are harmful to customers. Side effects from impurities in petroleum jelly in the manufacturing process have been implicated at causing cancer and long term damage to health. Artificial colours have been found to cause cancer in animals and many people experienced allergic reactions i.e. skin irritation and contact dermatitis. Therefore 'friendly' lip balm was formulated by substituting the base ingredient, i.e. petroleum jelly, with vegetable fats and incorporated with anthocyanin pigments from Hibiscus sabdariffa L. (roselle) and Brassica oleracea var. capitata f. rubra (red cabbage) as natural colorants. Anthocyanins are considered secondary metabolites, allowed as food additives and act as powerful antioxidants. The herbal lip balm samples were gamma irradiated (2.5, 5.0 and 10 kGy) at Mintec SINAGAMA, Malaysian Nuclear Agency, Bangi. The samples were tested for microbiology quality i.e. total microbial count and presence of yeast and mold. The results showed that there were no microbial and yeast/mold colonies were detected in non-irradiated samples (control) and after irradiation. The essential oils from herbs and spices included in the herbal lip balms not only improve the taste and aroma but also had potential as natural preservatives due to their antibacterial properties. Gamma irradiation at dose 2.5 kGy was suitable as minimum dose to decontaminate the herbal lip balm without affecting the colour and texture. From market survey, friendly lip balm is considered as a safe and attractive product, with multifunctional uses i.e. to prevent chapped lips, freshen the breath, reduces mouth odour and contributes to improving general health quality.

    In this project, the core technologies such as fabrication of eco-friendly and high-performance bioplastics, anionic exchange membranes for the energy generation, and anisotropic conductive films (ACF) for the electronic devices were developed by using an eco-friendly and low-energy consumption radiation. In the 1 st project group, the fabrication technologies of biodegradable polymer-based blends, biocompoistes, and foam were developed using a radiation crosslinking technology, and the possibility of their commercialization was evaluated through the fabrication of prototype products (fruits packaging material and adhesive) in the practical production lines. In the 2 nd project group, the fabrication technology of the anion exchange membranes for alkaline fuel cell were prepared by utilizing the inherent property of radiation such as high ionizing energy and penetrating depth. The ion exchange capacity, ion conductivity, high ionizing energy and penetrating depth. The ion exchange capacity, ion conductivity, high ionizing energy and penetrating depth. The ion exchange capacity, ion conductivity, mechanical property, and chemical stability of the prepared membranes were measured. The results of the MEA performance test, the maximum power density of 115 mW and operation for 200 hours, indicates the possibility of the use of anion exchange membranes for alkaline fuel cell. In the 3rd project group, the electron beam-induced room temperature and fast curable epoxy was developed and the mechanism of electron beam-induced curing was investigated using various analytical methods. On the basis of the physical and electrical characterization, the prepared ACF exhibited lower resistance and higher tensile strength compared to that of the commercialized one

    Full Text Available Demand for energy is growing across the globe due to the direct relationship between the well-being and prosperity of people and energy usage. However, meeting this growing energy demand in a safe and environmentally friendly manner is a key challenge. To this end, methyl esters (biodiesels have been and are being widely investigated as alternatives to fossil fuels in compression ignition engines. In this study, melon (Colocynthis Citrullus Lanatus oil was used to synthesize biodiesel (methyl ester using the transesterification method in the presence of a sodium hydroxide promoter. The emissions profile of the biodiesel was investigated by setting up a single-cylinder four-stroke air-cooled CI engine connected to a TD115-hydraulic dynamometer and an Eclipse Flue Gas Analyzer (FGA with model number EGA4 flue gas analyzer. The engine was run at engine speeds of 675, 1200 and 1900rpm for biodiesel/diesel blends at 21°C on a volume basis of 0/100(B0, 10/90(B10, 20/80(B20, 30/70(B30, 40/60(B40 and 50/50(B50. The test showed a downward trend in the emissions profile of the biodiesel, with remarkable reductions of about 55% in the dangerous-carbon monoxide exhaust gas pollutant and 33.3% in the unfriendly SOX from 100% diesel to B30-biodiesel concentration. Increasing the speed from 675 to 1200 and then to 1900 rpm also afforded further reductions in CO and SOX exhaust emissions. NOX however increased marginally by 2.1% from the same 100% diesel to the B30-biodiesel composition. Based on the remarkable reduction in CO and SOX and the marginal increase in NOX as the concentration of the biodiesel increased in the blends, the study concludes that melon oil methyl ester is an environmentally friendly fuel.

    Although guidelines generally state that physicians should not treat their family members or friends (nonpatients), physicians regularly receive medical requests from nonpatients. We aimed to explore junior and senior family physicians' experiences with and attitudes toward managing medical requests from nonpatients. We conducted a qualitative study with 7 focus groups with junior and senior physicians. We performed a thematic analysis during an iterative cycle of data collection and analysis. When confronted with a medical request from a nonpatient, physicians first oriented themselves to the situation: who is this person, what is he or she asking of me, and where are we? Physicians next considered the following interrelated factors: (1) nature/strength of the relationship with the nonpatient, (2) amount of trust in his/her own knowledge and skills, (3) expected consequences of making mistakes, (4) importance of work-life balance, and (5) risk of disturbing the physician-patient process. Senior physicians applied more nuanced considerations when deciding whether to respond, whereas junior physicians experienced more difficulties dealing with these requests, were less inclined to respond, and were more concerned about disturbing the existing relationship that a person had with his/her own physician. This study provides insight into the complexity that physicians face when managing medical questions and requests from nonpatients. Facilitated group discussions during which experiences are shared can help junior physicians become more confident in dealing with these complex issues as they formulate their own personal strategy regarding provision of medical advice or treatment to family and friends. © 2018 Annals of Family Medicine, Inc.

    Adolescent friends are often found to be similar. Similarity can be caused by selection and influence processes. This book examines selection and influence processes for delinquency, school attitudes, and alcohol use in early adolescence. For selection processes, we hypothesize that adolescents whose attributes are positively associated tend to become and stay friends. For influence processes, we hypothesize that adolescents tend to adjust their attributes to their friends' attributes. We ana...

    Friendship networks are an important source of peer influence. However, existing network studies vary in terms of how they operationalize friendship and friend's influence on adolescent substance use. This study uses social network analysis to characterize three types of friendship relations: (1) mutual or reciprocated, (2) directional, and (3) intimate friends. We then examine the relative effects of each friendship type on adolescent drinking and smoking behavior. Using a saturated sample from the Add Health data, a nationally representative sample of high school adolescents (N = 2,533 nested in 12 schools), we computed the level of exposure to drinking and smoking of friends using a network exposure model, and their association with individual drinking and smoking using fixed effect models. Results indicated that the influence from mutual or reciprocated type of friendship relations is stronger on adolescent substance use than directional, especially for smoking. Regarding the directionality of directional type of friendship relations, adolescents are equally influenced by both nominating and nominated friends on their drinking and smoking behavior. Results for intimate friends friendship relations indicated that the influence from "best friends" was weaker than the one from non-"best friends," which indicates that the order of friend nomination may not matter as much as nomination reciprocation. This study demonstrates that considering different features of friendship relationships is important in evaluating friends' influence on adolescent substance use. Related policy implications are discussed. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    2017-08-01

    The objective of this study was to examine the prospective relationship and changes in sedentary behavior between adolescent girls, their mothers and best friends over time. The results are based on 122 girls aged 11-12 years at baseline measurement, their mothers and best friends who completed ecological momentary assessment diary for the assessment of sedentary behavior. All measurements were taken at 3 time points separated by one year. We used structural equation modeling to examine associations among sedentary behavior of adolescent girls, their mothers and best friends. A linear growth model for adolescent girls' and their best friends' sedentary behavior fit the data well, revealing an overall significant increase in sedentary behavior across time. Initial levels of mothers' and best friends' sedentary behavior were positively related with sedentary behavior of adolescent girls. The changes of adolescent girls' and best friends' sedentary behavior across 3 years were positively related. Cross-lagged panel analysis demonstrated significant reciprocal effects between adolescent girls' and best friends' sedentary behavior. Mothers' sedentary behavior at baseline predicted daughters' sedentary behavior at 1-year follow-up and vice versa. From early to midadolescence, changes in adolescent girls' sedentary behavior were associated with changes in best friends' sedentary behavior. These findings suggest reciprocal associations between sedentary behavior of adolescent girls and their best friends.

  16. THE OVERDENSITY AND MASSES OF THE FRIENDS-OF-FRIENDS HALOS AND UNIVERSALITY OF HALO MASS FUNCTION

    2011-01-01

    The friends-of-friends algorithm (hereafter FOF) is a percolation algorithm which is routinely used to identify dark matter halos from N-body simulations. We use results from percolation theory to show that the boundary of FOF halos does not correspond to a single density threshold but to a range of densities close to a critical value that depends upon the linking length parameter, b. We show that for the commonly used choice of b = 0.2, this critical density is equal to 81.62 times the mean matter density. Consequently, halos identified by the FOF algorithm enclose an average overdensity which depends on their density profile (concentration) and therefore changes with halo mass, contrary to the popular belief that the average overdensity is ∼180. We derive an analytical expression for the overdensity as a function of the linking length parameter b and the concentration of the halo. Results of tests carried out using simulated and actual FOF halos identified in cosmological simulations show excellent agreement with our analytical prediction. We also find that the mass of the halo that the FOF algorithm selects crucially depends upon mass resolution. We find a percolation-theory-motivated formula that is able to accurately correct for the dependence on number of particles for the mock realizations of spherical and triaxial Navarro-Frenk-White halos. However, we show that this correction breaks down when applied to the real cosmological FOF halos due to the presence of substructures. Given that abundance of substructure depends on redshift and cosmology, we expect that the resolution effects due to substructure on the FOF mass and halo mass function will also depend on redshift and cosmology and will be difficult to correct for in general. Finally, we discuss the implications of our results for the universality of the mass function.

    Full Text Available Silver is a known disinfectant from ancient times, and it has been widely used for various purposes: for food and water disinfection, curing of wounds and as a universal antibiotic for a wide spectrum of diseases - until the Second World War and the discovery of penicillin. Until recently, it was assumed that silver, being a heavy metal, was toxic for humans and living beings. However, the newest research provides facts that the usage of silver, even for drinking water disinfection, is benign if it is added in small concentrations (in parts per billion. It has been shown in the newer scientific and technical literature that silver in colloidal form is a powerful (secondary disinfectant for drinking water, that it can be effectively used for the disinfection of water containers including swimming pools, installations in food industry, medicine, etc. Particularly, it has been shown that colloidal silver combined with hydrogen peroxide shows synergism having strong bactericidal and antiviral effects. The combination can be successfully used as a disinfectant in agriculture, food production and medicine. The original electrochemical process of production, the mechanism of physical-chemical reactions in that process and the mechanism of the antiseptic affect of the environmentally friendly disinfectant, based on the synergism of colloidal silver and hydrogen peroxide and the activity of electrochemically activated water, is shown. The starting solution was anolyte, obtained in electrochemical activation by water electrolysis of a highly diluted solution of K-tartarate in demineralized water (5.5-1CT4 M. The problem of electrolysis of very dilute aqueous solutions in membrane cells was particularly treated. It was shown that the efficiency of the electrolysis depends on the competition between the two processes: the rates of the processes of hydrogen and oxygen generation at the electrodes and the process of diffusion of hydrogen and hydroxyl ions

    Full text: Bio fuel production and use have been discussed this time in EC and in Latvia as alternative energy sources. The national resources allow producing liquid fuels - bio diesel and bi oethanol from rape seeds and grain correspondingly. Liquid bio fuels can be recommended especially for auto transport in big towns to reduce the pollution of air. A system for environmentally friendly production of bio fuel from agricultural raw materials has been developed, which permit a complex utilization of byproducts an wastes for obtaining of valuable food-stuffs and industrial products, providing the agricultural production requirements and supporting with local mineral fertilizers. Such a bio fuel production includes the agricultural and industrial productions in a united biotechnological system. Production objects of system interact: the products, by-products and wastes from one object are used as raw materials, auxiliary materials or heat carriers in other system's objects. This integrated agro-industrial production system would allow the production of feeds and chemical products, along with bio fuels. In this work, a model of a system for a conventional administrative rural region is presented, exemplified with the case of Latvia. The model is developed for three forms of bio fuel production, i.e. ethanol, bio diesel and biogas as local energy source. Bio diesel is produced using ethanol as transesterifying agent of rape-seed oil fatty acids. This bio diesel is a blend of rape-seed oil fatty acid ethyl esters (REE) and consists solely from renewable raw materials. The capacity of distillery of system is 40 million litters per year and bio diesel 35000 ton. Important for agriculture is protein reach press cakes the byproduct from bio diesel production (66000 t/y). This byproduct can be exported as well. Biogas reactors of system can be used for utilization of wastes from town if necessary. Recommended bio system occupates up to 150.000 ha of agriculture lands

    In recent years, waste disposal at workmen camp is one of the major problems being faced by many nations across the world. In the workmen colony at Chittapur, a series of kitchens were built for cooking purpose and a number of small canteens are also functioning. Considerable quantity of food waste is collected daily from these eateries and disposed at a faraway place. Food waste is highly degradable in nature, if not disposed properly it causes problems related to environmental pollution. Hence, it is very important to identify an environment friendly process rather than opt for land filling or any disposal method. We worked together to find a suitable eco-friendly solution for the food waste disposal at Chittapur site and suggested that biogas production through anaerobic digestion is a solution for the disposal and utilization of food waste for better purpose. This resulted in setting up a 500 kg per day food waste treatment biogas plant at Chittapur. This establishment is the first time in the construction industry at workmen camp in India. Anaerobic Digestion has been recognized as one of the best options that is available for treating food waste, as it generates two valuable end products, biogas and compost. Biogas is a mixture of CH4 and CO2 about (55:45). Biogas generated can be used for thermal applications such as cooking or for generating electricity. The digested slurry is a well stabilized organic manure and can be used as soil fertilizer. Plant design is to handle 500 kg of food waste /day. 27 kg LPG is obtained from 500kg of kitchen waste. The Value of 27 kg of LPG is Rs.2700/day. Daily 1000 litres of digested effluent was obtained. It is good organic manure with plant micro nutrients and macro nutrients. This can be used for growing plants and in agriculture. The value of manure per day is Rs.250/-. The annual revenue is Rs.10.62 lakhs and the annual expenditure is 1.8 lakhs. The net benefit is 8.82 lakhs. Payback period is 2.1 years. This process

    The adolescent Latino male mortality profile is an anomaly when compared to an otherwise more favorable overall U.S. Latino population mortality profile. Motor vehicle crash fatalities bear a considerable proportion of mortality burden in this vulnerable population. Friend influence and relational connection are two contextual domains that may mediate crash injury risk behavior in these adolescents. Our study goal was to assess the role of friend influence over time and relational connections associated with crash injury risk behavior (CIRB) in adolescent Latino males. Waves I and II data from the National Longitudinal Study of Adolescent Health were used. Scale of CIRB, and three relational connections; school connectedness, parent connectedness, and expectation of academic success were developed and tested. Friend nomination data were available and the index student responses were linked to friend responses. Linear regression was used to assess the relationship of relational connections and friend CIRB on index student CIRB at wave I and II. Longitudinal analysis did not show significant evidence for friend influence among adolescent Latino males on CIRB. The best predictor of CIRB at wave II for adolescent Latino males was their CIRB at wave I. Relational connections were important yet exaggerated cross-sectionally but their effect was substantially attenuated longitudinally. The lack of friend influence on CIRB for adolescent Latino males may be specific to this demographic group or characteristic of the sample studied. Prevention strategies that focus on modulating friend influence in adolescent Latino males may not yield the desired prevention effects on CIRB.

    In this paper, biodegradation performance of rapeseed insulating oil (RDB) and FR3 insulating oil (FR3) was studied by means of ready biodegradation method which was performed with Organization for Economic Co-operation and Development (OECD) 301B. For comparison, the biodegradation behaviour of 25# mineral insulating oil was also characterized with the same method. The testing results shown that the biodegradation degree of rapeseed insulating oil, FR3 insulating oil and 25# mineral insulating oil was 95.8%, 98.9% and 38.4% respectively. Following the “new chemical risk assessment guidelines” (HJ/T 154 - 2004), which illustrates the methods used to identify and assess the process safety hazards inherent. The guidelines can draw that the two vegetable insulating oils, i.e. rapeseed insulating oil and FR3 insulating oil are easily biodegradable. Therefore, the both can be classified as environmentally-friendly insulating oil. As expected, 25# mineral insulating oil is hardly biodegradable. The main reason is that 25# mineral insulating oil consists of isoalkanes, cyclanes and a few arenes, which has few unsaturated bonds. Biodegradation of rapeseed insulating oil and FR3 insulating oil also remain some difference. Biodegradation mechanism of vegetable insulating oil was revealed from the perspective of hydrolysis kinetics.

    Summer brings the opportunity for many of us to spend time enjoying the company of our families and friends. It also brings a new generation of young people to CERN – the summer students.   We often talk about the extended CERN community as a being like a big family, where the common bond is the science we do. The summer students who join us every year are in many ways the newest additions to this family. This year we have welcomed 276 students in total, with an impressive 133 from non-Member states. As usual they are joining in the learning experience that the programme offers and taking the opportunity to socialise. However, this year they are showing a particular enthusiasm for developing activities together that are linked to spreading the message about CERN. They’ve shown great support for the CERN Summer Student Webfest – now in its second year - where they were invited to work in teams and design web apps that will encourage the public to learn more abou...

    This study examines coresident relationships in assisted living (AL) and identifies factors influencing relationships. We draw on qualitative data collected from 2008 to 2009 from three AL communities varying in size, location, and resident characteristics. Data collection methods included participant observation, and informal and formal, in-depth interviews with residents, administrators, and AL staff. Data analysis was guided by principles of grounded theory method, an iterative approach that seeks to discover core categories, processes, and patterns and link these together to construct theory. The dynamic, evolutionary nature of relationships and the individual patterns that comprise residents' overall experiences with coresidents are captured by our core category, "negotiating social careers in AL." Across facilities, relationships ranged from stranger to friend. Neighboring was a common way of relating and often involved social support, but was not universal. We offer a conceptual model explaining the multilevel factors influencing residents' relationships and social careers. Our explanatory framework reveals the dynamic and variable nature of coresident relationships and raises additional questions about social career variability, trajectories, and transitions. We discuss implications for practice including the need for useable spaces, thoughtful activity programming, and the promotion of neighboring through staff and family involvement.

    The E136 Tresfjord Bridge opened in October 2015, and crosses the Tresfjorden on the west coast of Norway. It is a concrete bridge with a total length of 1290 m, consisting of 19 viaduct spans, 60 m each, and a FCM (free cantilever method) main span of 160 m. The E136 is one of the most important transportation routes in the county of Møre and Romsdal and starts in Ålesund, and passes along Tresfjorden to Åndalsnes. The existing road is very narrow with speed limit of 60 km/h and characterizes by many accidents involving cars and people. The traffic flow is approximately ca 2500 vehicles a day, of this is 25% heavy vehicles. Those transport fresh salmon from the breeders in the fjords along the coast. To try to decrease the transportation time is very important for the fresh salmon. The bridge reduces the distance between Ålesund and Åndalsnes by 13 km. The speed limit is now 80 km/h, and with much less risk for accidents since there are separate lanes for cars and pedestrians over the whole bridge. This means that the bridge represents a human friendly and traffic efficient structure to the benefit for the people and the region.

    The primary objective of this study was to evaluate a range of calculation points on water retention curves (WRC) instead of the singularity point at air-entry suction in the pore-solid fractal (PSF) model, which additionally considered the hysteresis effect based on the PSF theory. The modified pore-solid fractal (M-PSF) model was tested using 26 soil samples from Yangling on the Loess Plateau in China and 54 soil samples from the Unsaturated Soil Hydraulic Database. The derivation results showed that the M-PSF model is user-friendly and flexible for a wide range of calculation point options. This model theoretically describes the primary differences between the soil moisture desorption and the adsorption processes by the fractal dimensions. The M-PSF model demonstrated good performance particularly at the calculation points corresponding to the suctions from 100 cm to 1000 cm. Furthermore, the M-PSF model, used the fractal dimension of the particle size distribution, exhibited an accepted performance of WRC predictions for different textured soils when the suction values were ≥100 cm. To fully understand the function of hysteresis in the PSF theory, the role of allowable and accessible pores must be examined.

    Most seedlings of crops are produced in solar greenhouse or nursery, from which some problems about energy waste and environment pollution arise. This study aims at investigating the characteristics and effect of an environmental friendly type seedling breeding system. The results demonstrate that crops can grow with a short period and little pollution in the new seedling breeding system with total manpower controllable environment that is not influenced by geography, climate and other natural conditions. By multilayer, nonplanar seedling breeding and annual batches arrangement, utilization ratio of unit area land and seedlings yield can be improved for several times and even more than 10 times. Conclusions can be obtained from the tomato seedling breeding experiments: (1) each growth index of tomato seedlings that are under the conditions of 291 μmol/m2 s artificial illumination intensity is remarkably better than those produced in greenhouse with natural lights. (2) The environment of the seedling breeding system can be accurately controlled. The segmented temperature changed management can be applied according to the photosynthetic characteristics of plants, and not affected by the outside environment, which makes each growth index of tomato seedling constant in different seasons. The seedlings thus grow strong and can achieve the level of commodity seedlings after 20-30 days. (3) The temperature and humidity environment of the seedling breeding system can be accurately controlled according to plants growth demands.

    Saving of toner/ink consumption is an important task in modern printing devices. It has a positive ecological and social impact. We propose technique for converting print-job pictures to a recognizable and pleasant color sketches. Drawing a "pencil sketch" from a photo relates to a special area in image processing and computer graphics - non-photorealistic rendering. We describe a new approach for automatic sketch generation which allows to create well-recognizable sketches and to preserve partly colors of the initial picture. Our sketches contain significantly less color dots then initial images and this helps to save toner/ink. Our bio-inspired approach is based on sophisticated edge detection technique for a mask creation and multiplication of source image with increased contrast by this mask. To construct the mask we use DoG edge detection, which is a result of blending of initial image with its blurred copy through the alpha-channel, which is created from Saliency Map according to Pre-attentive Human Vision model. Measurement of percentage of saved toner and user study proves effectiveness of proposed technique for toner saving in eco-friendly printing mode.

    In order to tap the full potential of optical metrology, a comprehensive knowledge of the measuring system properties is of particular importance. The surface characteristics, the sensor's orientation towards the device under test and even the measuring frequency affect the result. Understanding the function of particular components of the device under test must also be seen as a basic prerequisite for the definition of the inspection features which will make up the inspection plan. The problems arising from the complex application of optical metrology, mainly in machine integration and embedment into existing quality management, will be the central theme of two research projects. An emphases of the technical development will be on the integration of optical metrology into machine tools and production-related coordinate measuring machines while ensuring consistency of data and on the conceptual design of software interfaces for user-friendly application of optical metrology. For that purpose, database-supported automatic generation of measurement and digitization procedures from CAD data will be implemented. This work will centre around the definition of variable sensor parameters and the allocation and configuration of these parameters according to the measurement task at hand. The technological basis for these studies are a conoscopic sensor mounted on a coordinate measuring machine and a scanning triangulation sensor integrated into a five axis machine tool.

    Full Text Available The low density and good mechanical properties make magnesium and its alloys attractive construction materials in the electronics, automotive, and aerospace industry, together with application in medicine due to their biocompatibility. Magnesium AZ91D alloy is an alloy with a high content of aluminum, whose mechanical properties overshadow the low corrosion resistance caused by the composition of the alloy and the existence of two phases: α magnesium matrix and β magnesium aluminum intermetallic compound. To improve the corrosion resistance, it is necessary to find an effective protection method for the alloy surface. Knowing and predicting electrochemical processes is an essential for the design and optimization of protective coatings on magnesium and its alloys. In this work, the formations of nickel protective coatings on the magnesium AZ91D alloy surface by electrodeposition and chemical deposition, are presented. For this purpose, environmentally friendly electrolytes were used. The corrosion resistance of the protected alloy was determined in chloride medium using appropriate electrochemical techniques. Characterization of the surface was performed with highly sophisticated surface-analytical methods.

    Understanding how organ donors' families recover from their grief can help organ procurement organizations improve consent rates and increase the number of deceased donor organs available for transplant. To determine what helps the loved ones of deceased organ donors heal from their grief and loss, and to better understand families' needs during the consent process as a way of improving overall consent rates for organ donation. Written survey of all organ and tissue donors' families in the San Diego and Imperial County (California) service area during 2006 and 2007. Responses to the 20-question survey addressing factors that help healing from grief, as well as contextual information about the families' experience at the hospital and the consent process. Most respondents (84%) indicated that family support was the most helpful thing in dealing with their grief, followed by the support of friends (74%) and religious and cultural beliefs (37%). Most (75%) indicated that they agreed to donation so that something positive could result from their loss. Most respondents (93%) felt that they were given enough information to make an informed decision about donation, and 6% indicated that the donation process interfered with funeral or memorial arrangements. More than 95% understood that their loved one had died before they were approached for consent. Consistent with previous studies, 12% said they still had unanswered questions about aspects of donation, and 15% of respondents indicated that the discussion about organ donation added more emotional stress to their overall experience.

    2010-01-01

    Development of herbal lip balm using natural bio resources namely plat pigments and essential oils was carried out with the main objective to replace chemical based ingredients that have been implicated at causing side effects and damages to health. Edible vegetable fats such as cocoa butter or shea butter in the range of 20-30 % could replace petroleum jelly as base ingredient. Side effects from impurities in petroleum jelly in the manufacturing process have been implicated at causing cancer and long term effects. Anthocyanin pigments, extracted from selected local plants, were used as natural coloring agent for lip balms. Pigment from Hibiscus sabdariffa L. (roselle) and Hylocereus polyrhizus (pittaya fruit) at 10-20 % could provide acceptable colours, act as secondary metabolite and seemed to be the most stable compared to other pigments from Hibiscus rosa sinensis, Brassica oleracea, Amaranthus gangeticus and Solanum lycopersicum. Honey (10-20 %) with its known benefits to health was added into the formulation to increase the intensity of the colour. Essential oils from spices and local herbs that added to the products for flavours and aroma have the potential as preservative due to its antibacterial properties. Irradiation at 2.5 kGy was sufficient to decontaminate the products without affecting the products physical characteristics. With this technology and incorporation of natural ingredients, friendly herbal lip balm is considered as a safe and attractive product, with multifunctional uses namely to prevent chapped lips, freshen the breath, reduces mouth odour and contributes to improving general quality.

    2012-02-01

    Full Text Available If the sentences or phrases like Fast Food-Konzept in Chile, Leonardo goes Gastronomie, Der Claim „Inspiration for modern living“, WM-Countdown läuft; Deutschland ist die fünftgrößte Incoming-Destination weltweit und … are considered, the first impression is that this is a typical mixture of both English and German. To all intents and purposes, they support the main part of a definition of pidgin language. Communication plays a central role in tourism. As emphasized by numerous authors, it is a personification of tourism; conversely tourism could be said to totally encompass a system of communication. As it is a crucial component of the industry, tourist discourse not only serves as a medium for buying/selling tourist products, it also assumes the role of the product itself within the complexity of various economic, technological and political processes in tourism. If analyzed within linguistic norms, discussion of Anglo-American influence on the German tourist discourse should focus on the problem of erosion of the national language, due to the impact of these Ango-Americanisms. The German tourist discourse aims at a customer-friendly approach in order to attract potential buyers or guests, all of which results in a slightly pidginized version of the German tourist discourse.

    In this work, positively charged nanocapsules have been developed for potential ocular delivery exploiting the deposition of PLA onto the droplet surface of a W/O nanoemulsion prepared by the reversed procedure of the PIT method. PLA in combination with different amounts of various oils and surfactants have been studied in order to select the best formulation for polymeric nanocapsule preparation. The traditional visual observation together with the Turbiscan(®) technology were exploited in order to identify the best combination of polymer/oil for nanocapsule preparation. Two different primary surfactants (Span(®) 60 and Span(®) 80) have been tested to select their influence on the field of existence of the nanoemulsion by the construction of the pseudoternary phase diagrams. Cationic hybrid NC have been prepared by the addition of a coating layer of DDAB. The physico-chemical and morphological properties of all the prepared nanocapsules have been evaluated and compared by PCS, DSC and AFM. Therefore, positively charged nanocapsules can be easily prepared by a simple eco-friendly technique that exploits biocompatible materials avoiding a large input of mechanical energy as a potential ocular delivery systems for hydrophilic compounds or gene materials.

    Nowadays, the refrigeration is responsible of about 15% of the overall energy consumption all over the world. Actually most of the refrigerant fluids working in vapor compression plants (VCPs) are environmentally harmful, since they presents high GWP (Global Warming Potential), which leads to a substantial warming of both earth surface and atmosphere. Electrocaloric refrigeration (ER) is an innovative, emerging refrigeration technique based on solid state refrigerant that shows a great potential. It fits in the context of environment-friendly refrigeration systems, whom are spreading increasingly to replace VCPs. ER is founded on electrocaloric effect that is a physical phenomenon found in materials with dielectric properties, electrocaloric materials. The thermodynamical cycle that best is addressed to the electrocaloric refrigeration is Active Electrocaloric Regeneration cycle (AER) that consists of two adiabatic and two isofield stages. The core of an electrocaloric refrigerator is the regenerator whom operates both as refrigerant and regenerator in an AER cycle. In this paper, we compare the energetic performance of a commercial R134a refrigeration plant to that of an electrocaloric refrigerator working with an AER cycle. The comparison is performed in term of TEWI index (Total Equivalent Warming Impact) that includes both direct and indirect contributions to global warming.

    2017-12-01

    Full Text Available Concrete pavements as concrete road slab, appear as a strong alternative for flexible superstructures especially because of their low cost for maintenance and repair and the high performance they show under heavy axle loads. The design of these concrete road slabs is quite different from the traditional concrete and reinforced concrete structures’ design. In the design for this kind of pavements, traffic conditions should be defined properly and considered an addition to the concrete and platform properties. There have been designing methods developed based on both experimental and mechanic foundations for concrete pavements. The most important ones of these methods are AASHTO (1993 and PCA (1984. In both design methods, it’s significant to know the maximum deflections and maximum strains the vehicles’ loads cause on the pavement. The calculation of this maximum deflections and maximum strains can be done via the finite element method or the closed formulas which have been developed by Westergaard. In this study, a user-friendly software has been developed based on AASHTO 1993, PCA 1984 design methods and Westergaard formulas. Thanks to this software, the user who wants to design the concrete pavement as concrete road slab can obtain the essential parameters automatically by entering the required data for the design.

    2005-01-01

    One of CERN's electrical substations, at Prévessin. Electricity is one of CERN's closest allies. Without it, none of the physicists' extraordinary instruments would work. It is electricity that will guide and accelerate particles around the 27-km ring of the world's most powerful accelerator, the LHC. In the giant magnets inside the experiments electricity is also used to produce a magnetic field 200,000 times greater than the Earth's own magnetic field. Inside the detectors, the resulting magnetic force is used to bend the trajectories of the particles, allowing them to be identified and helping us gain a better understanding of what has happened at the heart of the collisions.

    Full Text Available Environment friendly products such as fuels and lubricants are among the candidates which are studied in several countries including Egypt. The purpose of this work was to utilize commercially available palm oil and Jatropha oil for the production of biolubricants, through two stages of Transesterification. The first stage is the process of using methanol in the presence of potassium hydroxide to produce biodiesel. The second stage is the reaction of biodiesel with trimethylolpropane using sodium methoxide as catalyst to yield palm or Jatropha oil base trimethylolpropane esters (biolubricants. Palm oil based trimethylolpropane esters with yield of 97.8% was obtained after 4 h of reaction at 130 °C. Under similar reaction conditions, Jatropha oil based trimethylolpropane esters with a yield of 98.2% was obtained. The resulting products were confirmed by FTIR and evaluated by ASTM analyses. The obtained Jatropha oil based trimethylolpropane esters exhibited high viscosity indices (140, low pour point temperature (−3 °C, and moderate thermal stabilities and met the requirement of commercial industrial oil ISO VG46 grade. In spite of the high pour point of Palm oil based trimethylolpropane esters (5 °C, which needs pour point depressant to reduce the pour point, other lubrication properties such as viscosity, viscosity indices and flash point are comparable to commercial industrial oil ISO VG32 and VG46.

    Studies on the significance of age-friendly environments towards quality of life among older adults have been limited. This study aimed to examine the association between age-friendly environments and quality of life among Thai older adults. Cross-sectional interview survey data were collected from 4183 older adults (≥60 years) using multistage stratified systematic sampling from all four regions in Thailand. The outcome variable was the World Health Organization Quality of Life (WHOQOL-BREF) scale, while independent variables included sociodemographic factors, having a health problem, and neighbourhood age-friendly environment variables. In multivariable logistic regression, significant age-friendly environments predictors of quality of life included walkable neighbourhood, neighbourhood aesthetics, neighbourhood service accessibility, neighbourhood criminal safety, neighbourhood social trust, neighbourhood social support, and neighbourhood social cohesion. The present study confirms the important role of age-friendly neighbourhoods in terms of physical and social environments towards the quality of life of older adults. PMID:28282942

    The goal of the present study was to explore patterns of communication between adolescents and their friends across both "online" and "in-person" contexts. The participants were adolescents (n = 727) aged 11-16 years attending middle schools in urban and rural areas of Italy. Participants completed daily logs of their in-person and online contacts with friends for 20 consecutive school days. Girls reported more total contacts with their friends than did boys as well as friendships that were closer and more intimate. However, boys indicated more contact than girls via electronic communication and online. Contacts with peers in general were less frequent among the older participants, perhaps because of increasing academic demands. Participants who complemented in-person contact with friends with electronic contact were less lonely than their counterparts who were less versatile in accessing different modalities of making contact with friends.

    Using panel data from a junior high school system in an urban area of Florida, we examine whether adolescents' best same-sex and best opposite-sex friends' sexual intercourse behavior increases the likelihood that respondents who are virgins at round 1 will make the transition to intercourse between rounds of our study. We find no significant influence effects of friends of either sex for black males or females, or white males. In contrast, white females are influenced by the sexual behavior of both their best female friend and best male friend. A virgin white female whose best friends of both sexes were sexually experience at round 1 was almost certain to have sexual intercourse within the two years of our study.

    With the growing interest worldwide in making communities more age-friendly, it is becoming increasingly important to understand the factors that help or hinder communities in attaining this goal. In this article, we focus on rural and remote communities and present perspectives of 42 experts in the areas of aging, rural and remote issues, and policy who participated in a consensus conference on age-friendly rural and remote communities. Discussions highlighted that strengths in rural and remote communities, such as easy access to local leaders and existing partnerships, can help to further age-friendly goals; however, addressing major challenges, such as lack of infrastructure and limited availability of social and health services, requires regional or national government buy-in and funding opportunities. Age-friendly work in rural and remote communities is, therefore, ideally embedded in larger age-friendly initiatives and supported by regional or national policies, programs, and funding sources.

    The objectives of this study were to provide an economic assessment as well as a calculated projection of the costs that typical U.S. tertiary-care hospitals would incur through policy reconfiguration and implementation to achieve the UNICEF/World Health Organization Baby-Friendly® Hospital designation and to examine the associated challenges and benefits of becoming a Baby-Friendly Hospital. We analyzed hospital resource utilization, focusing on formula use and staffing profiles at one U.S. urban tertiary-care teaching hospital, as well as conducted an online survey and telephone interviews with a selection of Baby-Friendly Hospitals to obtain their perspective on costs, challenges, and benefits. Findings indicate that added costs for a new Baby-Friendly Hospital will approximate $148 per birth, but these costs sharply decrease over time as breastfeeding rates increase in a Baby-Friendly environment.

    Full Text Available The present study was created in order to customise the marketing mix for non-purchasers of eco-friendly products by studying their perspectives on the introduction of eco-friendly variants of the regular products that they are using in particular product categories (personal care and home care. Overall previous literature reviews in this area imply that there is a gap in the scientific literature on the marketing mix formulation for converting non-purchasers into purchasers of eco-friendly products to augment eco-friendly product sales and adopt green marketing. As literature reviews had clearly indicated that green purchasers have a very low percentage when compared to non-purchasers, the purpose is to create new opportunities for successful green marketing as the study tries to convert non-purchasers into purchasers. We used descriptive research design to study a sample of 885 respondents, who were surveyed in 2 cities in the Tamil Nadu state in India, to acquire an in-depth understanding of consumer behaviour that would enable the consumption of eco-friendly products among non-purchasers. The results reveal the marketing mix requirement and the eco-friendly aspects needed by the non-purchasers in order to buy the eco-friendly variants. The research sheds light on the product, price and promotion components that will attract non-purchases of eco-friendly products to buy eco-friendly products, thus facilitating green marketing mix adaptation. The study will provide valuable input for further research in formulating the marketing mix necessary to enable consumption of eco-friendly products in different geographical locations and various product categories.

    The Baby-Friendly Hospital Initiative (BFHI) increases exclusive breastfeeding. Breastfeeding protects against obesity and diabetes, conditions to which American Indians and Alaska Natives are particularly prone. As part of the First Lady'sLet's Move! in Indian Countryinitiative, the US Department of Health and Human Services' Indian Health Service (IHS) began implementing the BFHI in 2011. The IHS administers 13 US birthing hospitals. There are 5 tribally administered hospitals in the lower 48 states that receive IHS funding, and the IHS encouraged them to seek Baby-Friendly designation also. In the 13 federally administered hospitals, the IHS implemented a Baby-Friendly infant feeding policy, extensive clinician training, and Baby-Friendly compatible medical records. All hospitals also became compliant with the World Health Organization's International Code of Marketing of Breast-Milk Substitutes. Strategies and solutions were shared systemwide via webinars and conference calls. Quality improvement methods, technical assistance, and site visits assisted with the implementation process. Between 2011 and December 2014, 100% (13 of 13) of IHS federally administered hospitals gained Baby-Friendly designation. The first Baby-Friendly hospitals in Arizona, New Mexico, North Dakota, Oklahoma, and South Dakota were all IHS sites; 6% of all US Baby-Friendly hospitals are currently IHS hospitals. One tribal site has also been Baby-Friendly designated and 3 of the 5 remaining tribally administered hospitals in the lower 48 states are pursuing Baby-Friendly status. Baby-Friendly Hospital Initiative implementation systemwide is possible in a US government agency serving a high-risk, underprivileged population. Other systems looking to implement the BFHI can learn from the IHS model. © International Lactation Consultant Association 2015.

    High expectations for Norway's Centres for Environment-friendly Energy Research (FME).The FME centres address a broad range of areas, allcentral to developing the energy sector of the future. The activities of the eight centres established in 2009 focus on renewable energy, raising energy efficiency, energy planning, and carbon capture and storage (CCS). In 2011 three new FME centres were established which focus on social science-related energy research. The FME scheme is a direct follow-up of the broad-based political agreement on climate policy achieved in the Storting in January 2008, and of the national RandD Energi21 strategy submitted in February 2008 to the Ministry of Petroleum and Energy. In April 2008 the Research Council of Norway's Executive Board decided to launch a process to establish centres for environment-friendly energy research, and a funding announcement was issued that same year. In 2010 it was decided that additional FME centres would be established in the field of social science-related energy research. After a thorough assessment of each project (based on feasibility, scientific merit, potential to generate value creation and innovation, and composition of the consortium) eight applicants were selected to become FME centres in February 2009. A new call for proposals was issued in 2010, and three more centres were awarded FME status in February 2011. The objective of the FME scheme is to establish time-limited research centres which conduct concentrated, focused and long-term research of high international calibre in order to solve specific challenges in the energy sphere. The selected centres must exhibit higher goals, a longer-term perspective and a more concentrated focus than is required under other funding instruments for the same scientific area. The make-up of the centres is critical to achieving this objective. The centres bring together Norway's leading research institutions and key players in private enterprise, the

    Full Text Available This study is about child-friendly city (KLA. This research is motivated by the lack of attention of the local government in protecting children and the issuance of Law No. 35 of 2014 on Protection of Children, which mandates local government obligations in the care of the child. This study sought to describe the various efforts made by the government of Surakarta and Makassar in realizing the KLA, the following supporting factors and obstacles surrounding the KLA embodiment. By using descriptive method and combine it with a qualitative approach, this study found some important points about the efforts of local governments in realizing the KLA. In Surakarta, for example, there have been several child-friendly community health centers (puskesmas. The Puskesmas is equipped with a private lounge complete with a children’s playground. In addition, services for children such as nutrition garden, corner of breast milk, pediatrician, child counseling services and a child abuse victim services also continue to be equipped, and many other programs. No wonder the Ministry of Women Empowerment and Child Protection Republic of Indonesia assessment scoring 713 from a total value of 31 indicators contained in the KLA who had filled the city of Surakarta. Meanwhile, Makassar City has not done a lot of local government programs, because the relatively new Makassar proclaimed KLA and is still central to reform. Among the new programs are being implemented and the Government of Makassar is giving birth certificate free of charge, to build flats in slums, and make the two villages as a pilot project KLA. The factors that affect the embodiment of the KLA it is a commitment. Not only the commitment of the head region, but also all relevant parties. As a cross cutting issue, the KLA also requires institutional capacity. Not only is the capacity of Women Empowerment and Child Protection Agency as a leading sector in the KLA, but also all work units other related

    Full Text Available One of the main problem of inland waterways fisheries is the transportation of fish from ponds to fish market during low tide trough inland waterways with 0.6m water depth.The boat is experiences grounding due to water depth of the river is not sufficient for the fishing boat to carry fish at it’s maximum2 tones capacity or experience dead freight . This condition forces fisherman to wait until the high tide from the sea, this delay causes the quality of the fish is decreasing.Besides the problem dead freight  problem the existing vessel is causes environmental problem such as erosion of the river bank due to wake wash. The other important issue is the increases of fuel price and it’s scarcity.  This paper presents the results of comparison of existing monohull fishing boat and two other alternativecatamaran designs. The catamaran design alternatives are is ordinary catamaran and flat side catamaran.  Both of the catamaran fishing boat design shows that the catamaran boat with 0.5m draft is able to carry more than 2 tonnes payload during low tide water depth.  The CFD simulation results shows that flat side catamaran resistance is more than 17.7% lower compared to ordinary catamaran and 44% lower compared to monohull. It means that the consumption of flat side catamaran is lowest compared to two other type of hull design. The flat side catamaran also produces lowest wake wash compared to o two other design. The low wake wash means more friendly to environment.

    Full Text Available Nitration of toluene has been studied in the liquid phase over a series of modified zirconia catalysts.  Zirconia, zirconia- ceria (Zr0.98Ce0.02O2, sulfated zirconia and sulfated zirconia- ceria were synthesised by co precipitation method and were characterised by X-ray diffraction, BET surface area, Infra red spectroscopy analysis (FTIR, Thermogravimetric analysis (TGA, Scanning Electron Microscopy (SEM and Energy Dispersive X ray analysis (EDAX. The acidity of the prepared catalysts was determined by FTIR pyridine adsorption study. X-ray diffraction studies reveal that the catalysts prepared mainly consist of tetragonal phase with the crystallite size in the nano range and the tetragonal phase of zirconia is stabilized by the addition of ceria. The modified zirconia samples have higher surface area and exhibits uniform pore size distribution aggregated by zirconia nanoparticles. The onset of sulfate decomposition was observed around 723 K for sulfated samples. The catalytic performance was determined for the liquid phase nitration of toluene to ortho-, meta- and para- nitro toluene. The effect of reaction temperature, concentration of nitric acid, catalyst reusability and reaction time was also investigated. © 2013 BCREC UNDIP.

    Griebel, Anne; Watson, David; Pendall, Elise

    2017-11-01

    Biotic disturbances are affecting a wide range of tree species in all climates, and their occurrence is contributing to increasing rates of tree mortality globally. Mistletoe is a widespread group of parasitic plants that establishes long-lasting relationships with a diverse range of host tree species. With climate change, ecophysiological stress is increasing, potentially making trees more susceptible to mistletoe infection, which in turn leads to higher forest mortality rates. The perception of mistletoe presence in individual trees and forest stands is divided within the scientific community, leading to an ongoing debate regarding its impacts. Forest managers concerned about stand health and carbon sequestration may view mistletoe as a foe that leads to reduced productivity. In contrast, ecologists may see mistletoe as a friend, in light of the wildlife habitat, biodiversity and nutrient cycling it promotes. However, individual studies typically focus on isolated effects of mistletoe presence within their respective research area and lack a balanced, interdisciplinary perspective of mistletoe disturbance. With this conceptual paper we aim to bring together the positive and negative impacts of mistletoe presence on tree physiology, soil nutrient cycling as well as stand health and stand dynamics. We focus on the role of mistletoe-induced tree mortality in ecosystem succession and biodiversity. In addition, we present potential modifications of mistletoe presence on the energy budget and on forest vulnerability to climate change, which could feed back into stand dynamics and disturbance patterns. Lastly, we will identify the most pressing remaining knowledge gaps and highlight priorities for future research on this widespread agent of biotic disturbance.

    2005-11-15

    The success or failure of any biodigester depends mainly upon the suitability of the design, site for construction and quality of construction works, as well as quality of construction materials and workmanship involved during construction. This booklet provides the extensive information on various methods for selecting the appropriate size and site for construction, as well as construction work steps related to the Farmer's Friend model (2005) of biodigester. First, mason's responsibilities are explained. Second, the report continues with the sizes of available biodigesters and the quantity of feeding required. Then, the components of the biogas plant and instructions as to how to select the appropriate size are described. It continues with construction materials and appliances, and the selection of the construction site. Finally, the plant construction is explained from lay-out work to the construction of compost pits, finishing work and instructions to users. If the concerned mason/plumber strictly follows the instruction as described in this construction manual, the biodigester will function properly with the anticipated efficiency and the owner will get the return of his/her investment. This will encourage his/her relatives and neighbours to install biodigesters. However, if the biodigester functions poorly, nobody will be motivated to install it. Poor quality plants will harm the reputation of biogas technology and will have serious negative effects on promotion and extension activities. The masons should, therefore, be well aware that good quality plants will certainly increase the rate of installation with the demonstration effect that ultimately benefits itself, the farmer, and the country as a whole.

  8. Prospects of DLC coating as environment friendly surface treatment process.

    2011-06-01

    After first commercialization in 90's, the applications of diamond-like carbon (DLC) have been significantly expanded to tool, automobile parts, machineries and moulds to enhance wear and friction properties. Although DLC has many advantages like high hardness, low friction electrical insulating and chemical stability and has the possible market, its application in the field is still very limited due to the gaps of understanding between end-user and developer of its advantage of costing. Recently, one of the most popular issues in the surface modification is providing the long lasting super-hydrophilic or -hydrophobic properties on the material surface for the outdoor usage. A lot of material loss is caused due to water corrosion which has to do with the flow and contacts of water like fuel cell separator and air conditioner parts. The consequence of development of functional surface based on the hydrophilic or hydrophobic design for the important parts would be really helpful for materials to be cleaner and more energy effective. Here, we first reviewed the DLC technology and then examined the kind of surface modification as well as its merits and disadvantage. We also looked at how we can improve super-hydrophilic and super hydrophobic for the DLC coating layer as well as current status of technology and arts of DLC. In the end, we would like to suggest it as one of the environmental friendly industrial technology. Copyright © 2011 The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences.

  9. Thermal baths as quantum resources: more friends than foes?

    Science.gov (United States)

    Kurizki, Gershon; Shahmoon, Ephraim; Zwick, Analia

    2015-12-01

    In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One may try to suppress the bath effects by means of dynamical control, but such control does not always yield the desired results. We wish instead to take advantage of bath effects, that do not obliterate ‘quantumness’ in the system-bath compound. To this end, three possible approaches have been pursued by us. (i) Control of a quantum system faster than the correlation time of the bath to which it couples: such control allows us to reveal quasi-reversible/coherent dynamical phenomena of quantum open systems, manifest by the quantum Zeno or anti-Zeno effects (QZE or AZE, respectively). Dynamical control methods based on the QZE are aimed not only at protecting the quantumness of the system, but also diagnosing the bath spectra or transferring quantum information via noisy media. By contrast, AZE-based control is useful for fast cooling of thermalized quantum systems. (ii) Engineering the coupling of quantum systems to selected bath modes: this approach, based on field-atom coupling control in cavities, waveguides and photonic band structures, allows one to drastically enhance the strength and range of atom-atom coupling through the mediation of the selected bath modes. More dramatically, it allows us to achieve bath-induced entanglement that may appear paradoxical if one takes the conventional view that coupling to baths destroys quantumness. (iii) Engineering baths with appropriate non-flat spectra: this approach is a prerequisite for the construction of the simplest and most efficient quantum heat machines (engines and refrigerators). We may thus conclude that often thermal baths are ‘more friends than foes’ in quantum technologies.

    This work concerns the development of environmentally friendly encapsulation technology, specifically designed to incorporate corrosion indicators, inhibitors, and self-healing agents into a coating, in such a way that the delivery of the indicators and inhibitors is triggered by the corrosion process, and the delivery of self-healing agents is triggered by mechanical damage to the coating. Encapsulation of the active corrosion control ingredients allows the incorporation of desired autonomous corrosion control functions such as: early corrosion detection, hidden corrosion detection, corrosion inhibition, and self-healing of mechanical damage into a coating. The technology offers the versatility needed to include one or several corrosion control functions into the same coating.The development of the encapsulation technology has progressed from the initial proof-of-concept work, in which a corrosion indicator was encapsulated into an oil-core (hydrophobic) microcapsule and shown to be delivered autonomously, under simulated corrosion conditions, to a sophisticated portfolio of micro carriers (organic, inorganic, and hybrid) that can be used to deliver a wide range of active corrosion ingredients at a rate that can be adjusted to offer immediate as well as long-term corrosion control. The micro carriers have been incorporated into different coating formulas to test and optimize the autonomous corrosion detection, inhibition, and self-healing functions of the coatings. This paper provides an overview of progress made to date and highlights recent technical developments, such as improved corrosion detection sensitivity, inhibitor test results in various types of coatings, and highly effective self-healing coatings based on green chemistry.

    Although major etiological models highlight the importance of friends in the development of adolescent body image and eating problems, longitudinal research that comprehensively investigates possible direct and mediational relationships between these variables is lacking. Thus, this study aimed to examine prospective interrelationships between perceived friend influence, body dissatisfaction, and disordered eating in early adolescent girls, and whether these relationships differed across levels of body mass. A large Australian community sample of female high school students (N = 1,094; Time 1 M age = 12.3 years) completed a battery of self-report questionnaires assessing perceived friend influence, body dissatisfaction, and disordered eating at 3 yearly intervals. Height and weight were also measured at each time point. Structural equation modeling was used to investigate two separate models, in which Time 2 body dissatisfaction was hypothesized to mediate the relationship between Time 1 perceived friend influence and Time 3 dieting and bulimic behaviors. No significant direct or indirect pathways were found between friend influence and disordered eating. Unexpectedly, however, body dissatisfaction was found to prospectively predict girls' perception of friend influence. These findings were remarkably similar in both healthy and overweight girls. The findings suggest that friends may be more influential for those adolescents who have higher levels of body image concern, rather than contributing directly to the development of body dissatisfaction. The peer environment represents an important consideration in adolescent prevention and intervention programs.

    Not all cognitive collaborations are equally effective. We tested whether friendship and communication influenced collaborative efficiency by randomly assigning participants to complete a cognitive task with a friend or non-friend, while visible to their partner or separated by a partition. Collaborative efficiency was indexed by comparing each pair’s performance to an optimal individual performance model of the same two people. The outcome was a strong interaction between friendship and partner visibility. Friends collaborated more efficiently than non-friends when visible to one another, but a partition that prevented pair members from seeing one another reduced the collaborative efficiency of friends and non-friends to a similar lower level. Secondary measures suggested that verbal communication differences, but not psychophysiological arousal, contributed to these effects. Analysis of covariance indicated that females contributed more than males to overall levels of collaboration, but that the interaction of friendship and visibility was independent of that effect. These findings highlight the critical role of partner visibility in the collaborative success of friends. PMID:26619079

    Full Text Available While organic farming is well established in Europe a nd USA, it is still catching up in Asian countries. The government of South Korea has implemented environmentally friendly farming that encompasses organic farming. Despite the promotion of environmentally friendly farming, it still has a low share in South Korea and partially converted farming has emerged in some districts of South Korea. However, the partially converted farming has not yet been investigated by the government. Thus, our study implemented a financial analysis to compare the annual costs and net returns of conventional, partially converted and environmentally friendly farming in Gangwon Province. The result showed that environmentally friendly farming was more profitable with respect to farm net returns. To find out the factors affecting the adoption of environmentally friendly farming, multinomial logistic regression was implemented. The findings revealed that education and subsidy positively and significantly influenced the probability of farmers’ choice on partially converted and environmentally friendly farming. Farm size had a negative and significant relationship with only environmentally friendly farming. This study will contribute to future policy establishment for sustainable agriculture as recommended by improving the quality of fertilizers, suggesting the additional investigation associated with partially converted farmers.

  15. Adolescent alcohol use: Social comparison orientation moderates the impact of friend and sibling behaviour.

    2015-09-01

    Research has indicated that both peers and siblings influence adolescents' alcohol use (e.g., Windle, 2000, Appl. Dev. Sci., 4, 98). The present two studies examined whether social comparison orientation (SCO) moderates the effects of perceived friend and sibling alcohol use on adolescents' alcohol use cognitions and behaviours. Two studies examined the role of SCO as a moderator of social influence (perceived friend alcohol use in Study 1 and both perceived friend use and sibling-reported alcohol use in Study 2) on prototype perceptions and willingness to drink alcohol (Studies 1 and 2) as well as actual alcohol consumption (Study 2) among early adolescents. In Study 1, cross-sectional results indicated that SCO moderated the effect of perceived friend alcohol use on favourable images of drinkers and willingness to drink. Study 2 found that SCO moderated the effects of perceived friend use and sibling use on favourable images of alcohol users, willingness to use alcohol, and change in alcohol use over 3 years such that adolescents who reported engaging in social comparison more often reported greater willingness, more favourable images, and increases in alcohol use when perceived friend use or sibling use was high. These studies highlight the importance of SCO as a moderator of susceptibility to the social influences of friends and siblings and may hold important implications for adolescent alcohol use prevention programmes and models of health risk behaviour. © 2014 The British Psychological Society.

    Objectives Research has indicated that both peers and siblings influence adolescents' alcohol use (e.g. Windle, 2000). The present two studies examined if social comparison orientation (SCO) moderates the effects of perceived friend and sibling alcohol use on adolescents' alcohol use cognitions and behaviors. Design & Methods Two studies examined the role of SCO as a moderator of social influence (perceived friend alcohol use in Study 1 and both perceived friend use and sibling-reported alcohol use in Study 2) on prototype perceptions and willingness to drink alcohol (Studies 1 & 2) as well as actual alcohol consumption (Study 2) among early adolescents. Results In Study 1, cross-sectional results indicated that SCO moderated the effect of perceived friend alcohol use on favorable images of drinkers and willingness to drink. Study 2 found that SCO moderated the effects of perceived friend use and sibling use on favorable images of alcohol users, willingness to use alcohol, and change in alcohol use over three years such that adolescents who reported engaging in social comparison more often reported greater willingness, more favorable images, and increases in alcohol use when perceived friend use or sibling use was high. Conclusions These studies highlight the importance of SCO as a moderator of susceptibility to the social influences of friends and siblings and may hold important implications for adolescent alcohol use prevention programs and models of health-risk behavior.

    In their efforts to recruit and retain female employees, organizations often attempt to make their workplaces "family-friendly." Yet there is little research on how women view family-friendly policies, particularly women who experience gender-based stereotype threat, or the concern of being viewed through the lens of gender stereotypes at work. Pilot research with female managers ( N = 169) showed that women who experienced stereotype threat perceived more negative career consequences for utilizing family-friendly policies. We then conducted two studies to further probe this relationship. Study 1 replicated the relationship between stereotype threat and the perceived consequences of utilizing family-friendly policies among women who recently returned to work after the birth of a child ( N = 65). In Study 2 ( N = 473), female employees who reported feelings of stereotype threat perceived more negative consequences of utilizing family-friendly policies, but they also reported greater intentions to use these policies. Our findings suggest that female employees are susceptible to stereotype threat, which in turn is associated with more negative views of family-friendly policies. Thus, the mere provision of such policies may not create the kind of family-friendly workplaces that organizations are attempting to provide.

  18. Learning from Your Network of Friends: A Trajectory Representation Learning Model Based on Online Social Ties

    2017-02-07

    Location-Based Social Networks (LBSNs) capture individuals whereabouts for a large portion of the population. To utilize this data for user (location)-similarity based tasks, one must map the raw data into a low-dimensional uniform feature space. However, due to the nature of LBSNs, many users have sparse and incomplete check-ins. In this work, we propose to overcome this issue by leveraging the network of friends, when learning the new feature space. We first analyze the impact of friends on individuals\\'s mobility, and show that individuals trajectories are correlated with thoseof their friends and friends of friends (2-hop friends) in an online setting. Based on our observation, we propose a mixed-membership model that infers global mobility patterns from users\\' check-ins and their network of friends, without impairing the model\\'s complexity. Our proposed model infers global patterns and learns new representations for both usersand locations simultaneously. We evaluate the inferred patterns and compare the quality of the new user representation against baseline methods on a social link prediction problem.

    Rejection sensitivity (RS) refers to the tendency to anxiously expect, readily perceive, and overreact to experiences of possible rejection. RS is a clear risk factor for psychological maladaptation during early adolescence. However, there is growing evidence of significant heterogeneity in the psychological correlates of RS. To investigate when RS poses the greatest psychological risk during early adolescence, this study examines mutual best friendship involvement (or lack thereof) and the best friends' RS as potential moderators of the associations between RS and psychological difficulties. Participants were 150 7th grade students (58 boys; M age = 13.05 years) who nominated their best friends, and reported on their RS, social anxiety, and self-esteem. Results from a series of hierarchical multiple regression analyses indicated that mutual best friendship involvement and best friends' RS were both significant moderators when fear of negative evaluation (a type of social anxiety) served as the dependent variable. The association between RS and fear of negative evaluation was stronger for adolescents without mutual best friends than adolescents with mutual best friends. In addition, the association between RS and fear of negative evaluation was the strongest for adolescents whose best friends were highly rejection sensitive (relative to adolescents whose best friends were moderately or low in RS). Findings highlight the importance of considering best friendships in studies of RS and strongly suggest that, although having mutual best friendships may be protective for rejection sensitive adolescents, having a rejection sensitive best friend may exacerbate difficulties. The significance of friends in the lives of rejection sensitive adolescents is discussed as well as possible applied implications of the findings and study limitations.

  1. Best friends and alcohol use in adolescence: the role of the dopamine D4 receptor gene.

    The influence of friends and peers is theoretically one of the most consistent and important factors explaining adolescent alcohol use. However, not all adolescents are equally likely to be influenced by their friends' drinking behaviors. Genetic factors may underlie these inter-individual differences in susceptibility to the drinking behavior of friends. Because the long allele (≥ 7 repeats) of the dopamine D4 receptor (DRD4) gene has been associated with susceptibility to alcohol and alcohol-related cues, we tested whether associations between best friend's and adolescent's alcohol use differed for DRD4 genotypes. A Dutch nationwide sample of 308 adolescents (age 13 at baseline) participated in a prospective, community-based study with five annual waves. A cross-lagged path analysis was carried out in Mplus to examine bi-directional relations between friends' and adolescents' weekly alcohol use (number of drinks). A multi-group approach was applied to test for moderation effects of a 48-base pair variable number of tandem repeats polymorphism in exon 3 of the DRD4 gene. Additionally, with latent growth curve models, it was examined whether the interaction between friends' drinking and DRD4 genotype predicted the development of adolescents' alcohol use. Results showed that both cross-sectionally and longitudinally higher levels of friends' alcohol use resulted in higher levels of adolescents' alcohol consumption over time (and vice versa). No significant moderation of DRD4 genotype was found: Associations between adolescents' and friends' drinking did not differ for adolescent carriers of the DRD4 long allele, when compared with adolescents without the DRD4 long allele. Because this is the first study to examine DRD4 × friends' drinking effects prospectively, replication is essential. Future longitudinal studies, possibly with observational or diary designs, are needed to increase our understanding of the interplay between genetic and environmental risk factors

    The aim of the study was to assess the validity of family members/friends as proxies by comparing perceptions of satisfaction with care and decision making between critically ill patients and their family/friends. A comparative, descriptive cross-sectional study. Seven Critical Care Units across four public and military hospitals in the centre and southern regions of Jordan. A modified version of the Family Satisfaction-ICU (FS-ICU) questionnaire was distributed to Critical Care Unit (CCU) patients before hospital discharge. In addition, up to two family members/close friends were also asked to complete the questionnaire. A total of 213 patients (response rate 72%) and 246 family members/friends (response rate 79%) completed and returned the questionnaire. Although the majority of family members/friends and patients were satisfied with overall care, patients were generally significantly less satisfied (mean (SD) care subscale 75.6 (17.8) and 70.9 (17.3), respectively, (p=0.005). When individual items were examined, significant differences in nursing care (family/friends 80.1 (20.7) versus patient 75.9 (22.2), p=0.038) and inclusion in decision making (family/friends 53.9 (33.2) versus patient 62.0 (34.2), p=0.010) were found. The study showed a degree of congruence between patients and their family members/friends in relation to their satisfaction with the CCU experience. Thus, views of family/friends may serve as a proxy in assessing care and decision making processes of critically ill patients. Appropriate training of the critical care team and provision of strategies to address the concerns of patients' families are needed to improve overall patient satisfaction.

  5. Dr Google, porn and friend-of-a-friend: where are young men really getting their sexual health information?

    Science.gov (United States)

    Litras, Amy; Latreille, Sarah; Temple-Smith, Meredith

    2015-11-01

    Background Young men are vulnerable when it comes to sexual health. They attend the general practitioner (GP) less often than females and are less likely to be offered testing for sexually transmissible infections. Access to accurate health information and education is a cornerstone of primary prevention, yet we know very little about how, where and why young people obtain information about sexual health. One-on-one semi-structured interviews were conducted with 35 male students aged 16-19 years from two Victorian educational institutions for trade skills until data saturation was reached. Interviews were audio-recorded, transcribed and thematically analysed. The young men were poorly informed about sexual health. Their existing knowledge mainly came from school-based sexual health education, which while valued, was generally poorly recalled and provided only a narrow scope of physiological information. Young men seek sexual health information from various sources including family, the Internet, friends and pornography, with information from the latter three sources perceived as unreliable. GPs were seen as a source of trust-worthy information but were not accessed for this purpose due to embarrassment. Young men preferred the GP to initiate such conversations. A desire for privacy and avoidance of embarrassment heavily influenced young men's preferences and behaviours in relation to sexual health information seeking. The current available sources of sexual health information for young men are failing to meet their needs. Results identify potential improvements to school-based sexual education and online resources, and describe a need for innovative technology-based sources of sexual health education.

  6. Ukrainian realities of labeling of environmentally friendly products

    Full Text Available The basis of life of any society is a safe environment that is not only the guarantee of welfare and quality of life, but also the guarantee of the further development of human civilization. That is why in the modern world the issue of the preservation of the natural environment is of special actuality. The gradual awareness by humanity of new threats (high degree of concentration of harmful industries; high level of resource and energy consumption; lack of modern environmental technologies; slow but inevitable degradation of the gene pool of a population due to the consumption of poor quality and in most cases harmful products, etc. forced the society to seek new approaches to socio-economic development and environmental management. One of such approaches is the introduction of ecological and organic labeling. Marking is a source of information about the purity, safety and quality of the products offered in the market; effective information mechanism, which is a kind of quality mark for the offered products. The current practice of ecological and organic labeling aimed at the increase of level consumer's awareness and the changing models of purchasing behavior in the direction of environmental protection. The feature of most marking systems of environmentally friendly and safe products is the obligation of compliance with the established requirements used by producers of raw materials and technologies taking into account their potential environmental impact. Labeling of ecologically clean and safe products is reducing the negative impact on the environment and on the human's health. It is the consequence of changes in the economic environment, namely: the improvement of socio-ethical requirements to production; the increasing level of integration of producers and service providers; the customer's satisfaction in varieties of products; globalization of economic space; reduction of time for development, standardization and production. Labeling is

  8. A Climate-friendly Energy Future: Prospects for Wind

    Science.gov (United States)

    Huang, Junling

    The objective of this thesis is to evaluate the potential for wind as an alternative energy source to replace fossil fuels and reduce global CO 2 emissions. From 1995 to 2007, fossil fuels as the major energy source accounted for an addition of 89.3 Gt of carbon to the atmosphere over this period, 29 % of which was transferred to the ocean, 15 % to the global biosphere, with the balance (57 %) retained in the atmosphere. Building a low-carbon and climate-friendly energy system is becoming increasingly urgent to combat the threat of global warming. Onshore wind resources in the contiguous US could readily accommodate present and anticipated future US demand for electricity. The problem with the output from a single wind farm located in any particular region is that it is variable on time scales ranging from minutes to days posing difficulties to incorporate relevant outputs into an integrated power system. The issue of interconnection of wind farms is studied with specific attention to the physical factors that determine the temporal variability of winds in the near surface region of the atmosphere. From a global perspective, generation of electricity from wind is determined ultimately by the balance between the production and dissipation of kinetic energy in the atmosphere. The origin of wind energy from 1979 to 2010 is investigated. The atmosphere acts as a thermal engine to produce wind energy, absorbing heat at higher temperatures (approximately 256 K), releasing heat at lower temperatures (approximately 253 K), as a consequence producing wind energy at a rate of 2.45 W/m2, with a thermodynamic efficiency of 1.03 %. The continuous blowing of wind is maintained by the thermodynamic instability of the atmospheric system. A framework is constructed to probe the relationship between the energy and entropy of the atmosphere, and to quantify two variables, the maximum work and the maximum increase in entropy which represent the thermodynamic instability.

  9. Paul Ehrenfest, Niels Bohr, and Albert Einstein: Colleagues and Friends

    Science.gov (United States)

    Klein, Martin J.

    2010-09-01

    In May 1918 Paul Ehrenfest received a monograph from Niels Bohr in which Bohr had used Ehrenfest's adiabatic principle as an essential assumption for understanding atomic structure. Ehrenfest responded by inviting Bohr, whom he had never met, to give a talk at a meeting in Leiden in late April 1919, which Bohr accepted; he lived with Ehrenfest, his mathematician wife Tatyana, and their young family for two weeks. Albert Einstein was unable to attend this meeting, but in October 1919 he visited his old friend Ehrenfest and his family in Leiden, where Ehrenfest told him how much he had enjoyed and profited from Bohr's visit. Einstein first met Bohr when Bohr gave a lecture in Berlin at the end of April 1920, and the two immediately proclaimed unbounded admiration for each other as physicists and as human beings. Ehrenfest hoped that he and they would meet at the Third Solvay Conference in Brussels in early April 1921, but his hope was unfulfilled. Einstein, the only physicist from Germany who was invited to it in this bitter postwar atmosphere, decided instead to accompany Chaim Weizmann on a trip to the United States to help raise money for the new Hebrew University in Jerusalem. Bohr became so overworked with the planning and construction of his new Institute for Theoretical Physics in Copenhagen that he could only draft the first part of his Solvay report and ask Ehrenfest to present it, which Ehrenfest agreed to do following the presentation of his own report. After recovering his strength, Bohr invited Ehrenfest to give a lecture in Copenhagen that fall, and Ehrenfest, battling his deep-seated self-doubts, spent three weeks in Copenhagen in December 1921 accompanied by his daughter Tanya and her future husband, the two Ehrenfests staying with the Bohrs in their apartment in Bohr's new Institute for Theoretical Physics. Immediately after leaving Copenhagen, Ehrenfest wrote to Einstein, telling him once again that Bohr was a prodigious physicist, and again

    The Nordic countries at the same time exhibit a remarkably high participation rate of mothers and a more moderate decline in fertility rates compared to other Western countries. This has been attributed to the fact that the welfare state model and, especially, the family friendly policies chosen...... in the Nordic countries are unique. In this paper we evaluate the impact of Nordic countries' family friendly policies on employment, wages and children's well-being. We demonstrate that, although the `Nordic model' has been successful in boosting female employment, it is a costly solution. Furthermore, family......-friendly policies mainly directed towards giving mothers the right to be on long paid maternal leave have adverse effects on women's wages with consequences for gender equality. Indeed, extensive family-friendly schemes may even have created a `system-based glass ceiling' hindering women's career progression...

    Who is willing to expose himself or herself to narcissists on a long-term basis? Studies that address the interactions of narcissists focus mainly on their interactions with strangers. Hence, the aim of the present study was to investigate the extent to which two best friends' similarity in narcissism would influence their similarities in other personality profiles. A total of 290 best friends' dyads filled out measurements of the whole Dark Triad as well as the Big Five. For each personality domain, profile similarity and its dependence on the similarity in the Dark Triad were determined. Results showed that the friends' similarity in narcissism significantly predicted similarity in all Big Five domains. For the general Big Five similarity as well as extraversion, the effect of narcissism similarity was stronger for male than female or mixed friends. Similarity in psychopathy and Machiavellianism significantly predicted all domains except for openness and extraversion, respectively. © 2016 by the Society for Personality and Social Psychology, Inc.

  9. Marketing Animal-Friendly Products: Addressing the Consumer Social Dilemma with Reinforcement Positioning Strategies

    Science.gov (United States)

    Ingenbleek, Paul T.M.; van Trijp, Hans C.M.; van der Veen, Gerrita

    2017-01-01

    Simple Summary Modern production systems aimed at improving animal welfare are more costly than traditional systems. Animal-friendly products are therefore typically more expensive than mainstream products, which presents one of the main barriers to consumer animal-friendly product choice. To overcome this barrier, marketing strategies that associate animal welfare with different types of value, such as taste, healthiness or good feeling, may be useful. This article presents a theoretical framework with marketing strategies using various types of value, suitable for animal-friendly products to encourage consumers to buy animal-friendly instead of mainstream products. We also explain why some consumers, such as those with a rational or an intuitive thinking style, may be more sensitive to some strategies over others, giving directions to marketing managers on how to approach different types of consumers. Because the credibility of animal welfare claims is a critical issue in marketing animal-friendly products, we address this issue as well. Specifically, we propose that, to gain consumer trust, companies selling animal-friendly products need to take into account the impact of their overall strategy on the effectiveness of marketing strategies for individual products and that they may need to collaborate with relevant stakeholders, such as media or animal-interest organizations. Abstract This article presents a conceptual framework that aims to encourage consumer animal-friendly product choice by introducing positioning strategies for animal-friendly products. These strategies reinforce the animal welfare with different types of consumption values and can therefore reduce consumers’ social dilemma, which is a major barrier to animal-friendly consumer choices. The article suggests how animal-friendly products can use various types of consumption values (functional, sensory, emotional, social, epistemic and situational) to create an attractive position relative to

    The present study explored whether similarity of students' food attitudes with those of their parents and friends varies as a function of both the food and type of measurement. We expected greater resemblance with parents for attitudes towards fruit and for implicit attitudes and greater resemblance with friends for attitudes towards snacks and for explicit attitudes. We compared the resemblance in implicit and explicit attitudes towards fruit and preference for sweet over savoury snacks between target-parent and target-friend pairings. The parental-peer mutual influence effect was separated from cultural effect by comparing real and random dyads. Target participants were 85 students who recruited one parent and one best friend each. All participants completed online two Implicit Association Tests and rated their liking for fruit and sweet/savoury snacks. Our target participants' attitudes towards fruit were predicted by those of their parents rather than friends, with this relationship being detected through implicit but not explicit measures. Conversely, target participants' preference for sweet over savoury snacks was predicted with those of their friends but not parents, with this relationship being detected through explicit but not implicit measures. Young adults' resemblance to parents and friends, in terms of food attitudes, seems specific both to the food type and to the attitude measure, suggesting that parents' influence concerns healthy food and is exerted at an implicit attitude level; whereas friends' influence concerns junk food and is exerted at an explicit attitude level. The theoretical and practical implications are discussed. ©2011 The British Psychological Society.

    Use of disordered eating behaviors is common among adolescents, and cross-sectional research has suggested that friends may be an important influence, especially among females. The current study seeks to expand upon this literature using a longitudinal design and a large, diverse sample of male and female youth. A total of 2,516 adolescents provided survey data at baseline (1998-1999) and follow-up (2003-2004) regarding their friends' involvement in dieting and their own experience of chronic dieting, unhealthy weight control, extreme weight control, and binge eating. General linear modeling was used to generate predicted probabilities of disordered eating at follow-up across four levels of friends' dieting at baseline, adjusting for baseline use of disordered eating, and other covariates. Interaction terms were used to determine whether the association between friends' dieting and disordered eating differed across age cohorts. One-third of participants reported that their friends were "not at all" involved in dieting at baseline, and 8.8% reported that their friends were very involved in dieting. Friends' dieting at baseline was positively associated with chronic dieting, unhealthy weight control behaviors, extreme weight control behaviors, and binge eating 5 years later among females, and with extreme weight control behaviors five years later among males. For both males and females, these associations were similar across age groups. Interventions targeting friendship groups rather than focusing solely on individuals may be an important strategy for the prevention of disordered eating. Health care providers may wish to ask adolescents about their friends' eating and dieting practices so as to address these issues in a clinical setting.

    Background Though bivariate relationships between childhood obesity, physical activity, friendships and television viewing are well documented, empirical assessment of the extent to which links between obesity and television may be mediated by these factors is scarce. This study examines the possibility that time with friends and physical activity are potential mechanisms linking overweight/obesity to television viewing in youth. Methods Data were drawn from children ages 10-18 years old (M = 13.81, SD = 2.55) participating in the 2002 wave of Child Development Supplement (CDS) to the Panel Study of Income Dynamics (PSID) (n = 1,545). Data were collected both directly and via self-report from children and their parents. Path analysis was employed to examine a model whereby the relationships between youth overweight/obesity and television viewing were mediated by time spent with friends and moderate-to-vigorous physical activity (MVPA). Results Overweight/obesity was directly related to less time spent with friends, but not to MVPA. Time spent with friends was directly and positively related to MVPA, and directly and negatively related to time spent watching television without friends. In turn, MVPA was directly and negatively related to watching television without friends. There were significant indirect effects of both overweight/obesity and time with friends on television viewing through MVPA, and of overweight/obesity on MVPA through time with friends. Net of any indirect effects, the direct effect of overweight/obesity on television viewing remained. The final model fit the data extremely well (χ2 = 5.77, df = 5, pobesity and television viewing in youth. These findings highlight the importance of moving from examinations of bivariate relationships between weight status and television viewing to more nuanced explanatory models which attempt to identify and unpack the possible mechanisms linking them.

    The constant and massive increase of biological data offers unprecedented opportunities to decipher the function and evolution of genes and their roles in human diseases. However, the multiplicity of sources and flow of data mean that efficient access to useful information and knowledge production has become a major challenge. This challenge can be addressed by taking inspiration from Web 2.0 and particularly social networks, which are at the forefront of big data exploration and human-data interaction. MyGeneFriends is a Web platform inspired by social networks, devoted to genetic disease analysis, and organized around three types of proactive agents: genes, humans, and genetic diseases. The aim of this study was to improve exploration and exploitation of biological, postgenomic era big data. MyGeneFriends leverages conventions popularized by top social networks (Facebook, LinkedIn, etc), such as networks of friends, profile pages, friendship recommendations, affinity scores, news feeds, content recommendation, and data visualization. MyGeneFriends provides simple and intuitive interactions with data through evaluation and visualization of connections (friendships) between genes, humans, and diseases. The platform suggests new friends and publications and allows agents to follow the activity of their friends. It dynamically personalizes information depending on the user's specific interests and provides an efficient way to share information with collaborators. Furthermore, the user's behavior itself generates new information that constitutes an added value integrated in the network, which can be used to discover new connections between biological agents. We have developed MyGeneFriends, a Web platform leveraging conventions from popular social networks to redefine the relationship between humans and biological big data and improve human processing of biomedical data.

The main objective of this study was to explore the older people's perspectives on an "elderly-friendly" hospital. Methods: Hospital was stratified by four domains including government, semi-government, community, and private. We interviewed 33 hospitalized older patients and four hospital managers between June and December 2014 in Kathmandu, Nepal, using purposive sampling technique. We executed a qualitative content analysis step with extensive review of the interviews. Final name of the theme was given after the agreement between the research team and experts to improve trustworthiness. Elderly-friendly services, expectation from government and hospital, and health policy related to senior citizen were developed as main themes. Results: Most of the participants were satisfied with the behavior of health personnel. However, none of the health personnel were trained with geriatric health care. Elderly-friendly hospital guidelines and policy were not developed by any hospitals. Older people health card, advocacy for older people's health and benefit, and hospital environment were the common expectations of older patients. Government policy and budget constraint were the main obstacles to promote elderly-friendly health care services. Conclusion: Elderly-related health policies, physical environments of hospital, elderly-friendly health manpower, advocacy, and other facilities and benefits should be improved and developed. There are urgent needs to develop elderly-friendly hospital policies and guidelines that

    Full Text Available OBJECTIVE: To analyze the association between physical activity and social support from parents and friends on the physical activity level among adolescents. METHODS: Data from 2,361 adolescents (56.6% females; mean age 16.4; SD = 1.2, from public and private high schools were analyzed. The physical activity level of the adolescents, parents, and friends were measured through a questionnaire. Parents' and friends' support and self-efficacy were measured using two previously tested scales. Data analysis was performed usingthe structural equation modeling in IBM(r SPSS(r AmosTM 20.0. RESULTS: Physical activity of friends was directly associated with physical activity level of adolescents. Physical activity of the father was associated with their sons, and the physical activity of mother was associated with their daughters. An indirect association was identified between the physical activity of parents and friends with physical activity level of the adolescents, mediated by social support. Social support was directly associated with physical activity in adolescents of both genders and indirectly mediated by self-efficacy. CONCLUSIONS: Parents and friends have a social influence on adolescents' level of physical activity through the mechanism of behavior modeling or through social support, mediated by self-efficacy.

    The influence of parents versus friends on youths' eating behavior has not been directly compared, and little is known about the developmental effects of social influences on their eating behavior. The objective was to compare the effects of mothers and friends on children's and adolescents' energy intake from sandwiches and from healthy and unhealthy snacks and dessert foods. Twenty-three children (ages 5-7 y) and 27 adolescents (ages 13-15 y) ate a meal with their mother on one occasion and with a same-sex friend on another occasion. Male and female children consumed less energy from unhealthy snacks when in the presence of their mothers than when in the company of their friends. Conversely, female adolescents consumed less energy from unhealthy snacks and more energy from healthy snacks when they were with their friends than when with their mothers. Food selection is differentially influenced by the source of social influence and the age and sex of the child. Parents may act as an inhibitory influence on unhealthy eating for younger children. Adolescent girls may try to convey a good impression of healthy eating when eating with same-sex friends, but the eating habits of teenage boys are not as influenced by the social context. This trial is registered at clinicaltrials.gov as NCT00875576.

    During human evolution, men and women faced distinct adaptive problems, including pregnancy, hunting, childcare, and warfare. Due to these sex-linked adaptive problems, natural selection would have favored psychological mechanisms that oriented men and women toward forming friendships with individuals possessing characteristics valuable for solving these problems. The current study explored sex-differentiated friend preferences and the psychological design features of same- and opposite-sex friendship in two tasks. In Task 1, participants (N = 121) categorized their same-sex friends (SSFs) and opposite-sex friends (OSFs) according to the functions these friends serve in their lives. In Task 2, participants designed their ideal SSFs and OSFs using limited budgets that forced them to make trade-offs between the characteristics they desire in their friends. In Task 1, men, more than women, reported maintaining SSFs for functions related to athleticism and status enhancement and OSFs for mating opportunities. In Task 2, both sexes prioritized agreeableness and dependability in their ideal SSFs, but men prioritized physical attractiveness in their OSFs, whereas women prioritized economic resources and physical prowess. These findings suggest that friend preferences may have evolved to solve ancestrally sex-linked adaptive problems, and that opposite-sex friendship may directly or indirectly serve mating functions.

    The aim of this study was to determine the influence of dyadic friendship relationships on adolescent physical activity (PA) behavior. Unique to this study was examination of the "best friend" dyad. Participants were 268 adolescents (13-18 years of age) of both sexes (boys n = 140, girls n = 128), constituting 134 best friendship dyads; 84 were reciprocal best friends and 50 were not. PA was evaluated with the short version of the International Physical Activity Questionnaire. The Actor-Partner Interdependence Model was tested using a hierarchical linear model. First, a null model was run to calculate intraclass correlation coefficient for each type of PA. Next, sex, age, and reciprocity in friendship were included in the model as PA predictors. The null models revealed significant intraclass correlation coefficient values for vigorous PA (VPA) (.32) moderate PA (MPA) (.31), and sitting behavior (.21), but not for walking. Age was the only predictor for VPA, whereas for MPA the predictors were sex and age of the partner. Reciprocity in friendship (best friend) was not a significant predictor for PA. These results indicate a high degree of similarity between best friend dyad in PA, except for walking. The age and sex of the best friend (partner) were important predictors of MPA. The reciprocity in friendship (being reciprocal best friends) was not a relevant variable. Copyright © 2013 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    The ability to form and maintain relationships with friends and romantic partners is a major developmental task for adolescents. Disagreeable youth are likely to struggle with this task, yet little is known about how they maintain their oppositional style from adolescence to adulthood. The current study examines the long-term implications of disagreeableness in a diverse sample of 164 adolescents assessed repeatedly across a 10-year period along with their friends and romantic partners. Disagreeableness at age 14-15 was assessed in observation with friends. Disagreeableness was then examined as a predictor of both future relationship quality with friends at age 16 and romantic relationships at age 21. The results indicate that although disagreeable youth do not report any relationship struggles, both their friends and romantic partners see their relationships as being low in quality. Findings suggest a developmental process by which disagreeable adolescents maintain their oppositional style through a mechanism of relationship blindness, as they simply are unable to see the relationship issues that their friends and partners clearly perceive.

    The present study was designed to examine best friend influence over alcohol intoxication and truancy as a function of relative perceptions of friendship satisfaction. The participants were 700 adolescents (306 boys, 394 girls) who were involved in same-sex best friendships that were stable from one academic year to the next. Participants completed self-report measures of alcohol intoxication frequency and truancy at 1-year intervals. Each member of each friendship dyad also rated his or her satisfaction with the relationship. At the outset, participants were in secondary school (approximately 13-14 years old) or high school (approximately 16-17 years old). More satisfied friends had greater influence than less satisfied friends over changes in intoxication frequency and truancy. Problem behaviors of less satisfied friends increased over time if the more satisfied friend reported relatively higher, but not relatively lower, initial levels of drinking or truancy. The results support the hypothesis that adolescent friends are not similarly influential. The power to socialize, for better and for worse, rests with the partner who has a more positive perception of the relationship.

    Although friends and siblings are considered to be important role models in adolescents' peer contexts, these peer influences on adolescent alcohol consumption over time are seldom examined simultaneously in a within-family design. The present study examined the relative impact of alcohol use of the best friend, adolescent sibling and sibling's best friend on the development of alcohol consumption during adolescence. Data reported in this study are part of an ongoing longitudinal questionnaire study among families with two adolescent siblings (N=416). Results from structural equation modeling showed a strong similarity in drinking between best friends and adolescents cross-sectionally. Over time, however, only marginal effects of friends alcohol use on drinking of the youngest sibling, and no effects for the oldest sibling were found. Robust evidence was found for peer-selection processes. In addition, we found a moderate to high relative similarity in drinking within sibling pairs, but no longitudinal effect of sibling's drinking. We also found no support for a possible additional influence of sibling's best friend's drinking on adolescent drinking. Therefore, we tested several potential moderating variables on peer influences, but found no effects of a set of relationship characteristics or individual characteristics on the links between peer and adolescent drinking over time.

    Physical activity (PA) tends to decline throughout the college years, and close friends' influence is known to be an important factor in maintaining PA. This study examined the actor effect and partner effect between an individual and his/her friend regarding the influence of self-efficacy and social support on PA among Korean college students. Cross-sectional survey data from 108 pairs of individual students and friends were analyzed. The survey questionnaire measured PA, self-efficacy toward exercise, social support for PA, anxiety and depression, community environments, and perceived health status. Structural equation modeling with path analysis was conducted to test Actor-Partner Interdependence Model (APIM) explaining close relationships on PA.

    Full Text Available Self-management of diabetes is challenging, especially for adolescents who face multiple changes, including closer peer relationships. Few studies have explored how friends can provide constructive support in this effort. The present research investigated, in two qualitative studies, the perceptions of adolescents with diabetes and their friends with respect to the positive social support that friends can offer. In study 1, 28 adolescents aged 12–15 with type 1 diabetes participated in online focus groups. In study 2, 11 of these adolescents were interviewed in person together with their best friends. The data were analysed by means of content analysis. In study 1, the adolescents with diabetes identified various supportive behaviours of friends, particularly concerning emotional support: treating them normally, showing interest, having fun, providing a distraction, and taking their diabetes into account. They differed in their attitude towards support, and this influenced which behaviours they perceived as supportive. Study 2 showed that the adolescents with diabetes and their friends often had similar opinions on the desired degree of support. Fear of stigmatization and sense of autonomy withheld some adolescents with diabetes from soliciting more support. These insights can be useful in patient education aiming to promote social support.

    2016-03-01

    In the current study I used mixed methods to explore the messages that undergraduate women ( n = 415) reported receiving from their male and female friends regarding sex and romantic relationships. Reports of friends' messages varied widely and entailed both support for and criticism of sexual gatekeeping and sex positivity (e.g., sexual agency) and advice regarding sex and romantic relationships. Four individuals, including the author, developed codes to examine this wide range of responses to sexual expectations and prohibitions and independently and reliably coded the data. Response patterns illustrate that reports of female friends' messages were typically longer and more nuanced than reports of male friends' messages. Sex-positive messages and sexual gatekeeping messages were frequently reported simultaneously, and this pattern of co-occurrence illustrates the tensions between diverse discourses regarding women's sexuality. The diversity in reports of friends' messages challenges popular notions that friends' influences are wholly problematic and highlights a need for more gender-focused sex education curricula.

    This study assessed early adolescents' sexual communication with dating partners, parents, and best friends about six sexual health topics: condoms, birth control, STDs, HIV/AIDS, pregnancy, and abstinence/waiting. Using a school-based sample of 603 youth (ages = 12–15; 57% female; 46% Caucasian), we examined communication differences across demographic and developmental factors, tested whether communication with parents and best friends was associated with greater communication with partners, and examined associations between communication and condom use. Over half of participants had not discussed any sexual topics with their dating partners (54%), and many had not communicated with parents (29%) or best friends (25%). On average, communication was more frequent among adolescents who were female, African American, older, and sexually active, despite some variation in subgroups across partner, parent, and friend communication. Importantly, communication with parents and friends – and the interaction between parent and friend communication – was associated with increased communication with dating partners. Further, among sexually active youth, increased sexual communication with partners was associated with more frequent condom use. Results highlight the importance of understanding the broader family and peer context surrounding adolescent sexual decision-making and suggest a possible need to tailor sexual communication interventions.

    Full Text Available A research field in the area of social networks (SNs is the identification of some types of users and groups. To facilitate this process, a SN is usually represented by a graph. The centrality measures, which identify the most important vertices in a graph according to some criterion, are usual tools to analyze a graph. One of these measures is the PageRank (a measure originally designed to classify web pages. Informally, in the context of a SN, the PageRank of a user i represents the probability that another user of the SN is seeing the page of i after a considerable time of navigation in the SN. In this paper, we define a new type of user in a SN: the best current friend. The idea is to identify, among the friends of a user i, who is the friend k that would generate the highest decrease in the PageRank of i if k stops being his/her friend. This may be useful to identify the users/customers whose friendship/relationship should be a priority to keep. We provide formal definitions, algorithms and some experiments for this subject. Our experiments showed that the best current friend of a user is not necessarily the one who has the highest PageRank in the SN nor the one who has more friends.

    We present MADANALYSIS 5, a new framework for phenomenological investigations at particle colliders. Based on a C++ kernel, this program allows us to efficiently perform, in a straightforward and user-friendly fashion, sophisticated physics analyses of event files such as those generated by a large class of Monte Carlo event generators. MADANALYSIS 5 comes with two modes of running. The first one, easier to handle, uses the strengths of a powerful PYTHON interface in order to implement physics analyses by means of a set of intuitive commands. The second one requires one to implement the analyses in the C++ programming language, directly within the core of the analysis framework. This opens unlimited possibilities concerning the level of complexity which can be reached, being only limited by the programming skills and the originality of the user.

    It is well documented that friends' externalizing problems and negative parent-child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings' externalizing problems and sibling-adolescent negative interactions on adolescents' externalizing problems, while examining and controlling for similar linkages with friends and parents. Questionnaire data on externalizing problems and negative interactions were annually collected from 497 Dutch adolescents (M = 13.03 years, SD = 0.52, at baseline), as well as their siblings, mothers, fathers, and friends. Cross-lagged panel analyses revealed modest unique longitudinal paths from sibling externalizing problems to adolescent externalizing problems, for male and female adolescents, and for same-sex and mixed-sex sibling dyads, but only from older to younger siblings. Moreover, these paths were above and beyond significant paths from mother-adolescent negative interaction and friend externalizing problems to adolescent externalizing problems, 1 year later. No cross-lagged paths existed between sibling-adolescent negative interaction and adolescent externalizing problems. Taken together, it appears that especially older sibling externalizing problems may be a unique social risk factor for adolescent externalizing problems, equal in strength to significant parents' and friends' risk factors. © 2013 The Authors.

    This article presents a conceptual framework that aims to encourage consumer animal-friendly product choice by introducing positioning strategies for animal-friendly products. These strategies reinforce the animal welfare with different types of consumption values and can therefore reduce consumers' social dilemma, which is a major barrier to animal-friendly consumer choices. The article suggests how animal-friendly products can use various types of consumption values (functional, sensory, emotional, social, epistemic and situational) to create an attractive position relative to their competitors. It also explains why some consumer segments, such as those with a specific thinking style, may experience a stronger effect of some strategies, giving directions on how to approach different types of consumers. Finally, building on research asserting that animal welfare is a credence product attribute, the article proposes moderating effects of two factors that help consumers to evaluate the credibility of animal welfare claims, namely corporate social responsibility strategy and the role of stakeholders. Here it concludes that companies selling animal-friendly products need to be aware of the impact of their overall strategy on the effectiveness of positioning strategies for individual products and that, to gain consumer trust, they may need to collaborate with relevant stakeholders, such as media or animal-interest organizations.

The research hypothesis was that using the computer to communicate with new online friends through social network sites or playing games with offline friends is associated with D/HH friendship qualities, because it removes certain communication barriers D/HH face in offline communication settings. With online questionnaires the relation between computer use and online, mixed (offline friend who you also speak in online settings, and offline friendship quality of D/HH and hearing students (18-25 years was compared in both the Netherlands (n = 100 and the United States (n = 122.

Results showed that, in general, D/HH students' friendship qualities and levels of well-being were similar to their hearing peers. The quality of the mixed friendships was positively related to well-being. Furthermore, the frequency of pc use with both online and offline friends was positively related to friendships qualities in both hearing and D/HH students. A combination of the online and offline friendship seems to be the most important friendship type for both hearing and D/HH students and it is worthwhile to encourage this friendship type.

    To examine the long-term effect of a female adolescent's exposure to a peer's childbirth on fertility, schooling, and earnings. Estimating causal peer effects in fertility is challenging because the exposure variable (peer pregnancy and childbirth) is nonrandomly assigned. Miscarriages in early pregnancy occur spontaneously in a significant proportion of pregnancies and, therefore, create a natural experiment within which the causal effect of childbirth can be examined. This exploratory study compared adjusted fertility, educational, and labor market outcomes of female adolescents whose adolescent pregnant friend gave birth to female adolescents whose pregnant friend miscarried. Longitudinal data from the National Longitudinal Study of Adolescent Health were analyzed using logistic, ordinal logistic, linear, and log-linear regressions. Females whose adolescent pregnant friends gave birth (instead of miscarried) had decreased adolescent sexual activity, pregnancy, and teen childbearing and increased educational attainment, but there were no significant long-term effects on total fertility or differences in labor market outcomes, relative to females whose pregnant adolescent friend miscarried. Adolescent females appear to learn vicariously from teen childbearing experiences of their friends, resulting in delayed childbearing and higher educational attainment. Interventions that expose adolescents to the reality of teen motherhood may be an effective way of reducing the rates of teen childbearing and improving schooling.

    The present study examined associations between use of protective behavioral strategies (PBS) by college students and their friends and drinking-related outcomes during Spring Break (SB). Moreover, this study examined the influence of friends’ own PBS use on participants’ PBS use during SB. Participants included college students (N = 694) and their nominated friends (N = 131) who were part of a larger study of SB drinking. Data were collected via web-based surveys that participants and friends took after SB, which assessed SB PBS, drinking, and related negative consequences. Results indicated that higher levels of Serious Harm Reduction (SHR) strategies and Limiting/Stopping (LS) strategies were associated with increased consumption, higher likelihood of experiencing any consequences, and an increased number of consequences. A different pattern emerged for Manner of Drinking (MD) strategy use; participants utilizing higher levels of MD strategies drank less and had fewer consequences. LS and MD strategies used by the participant’s friends appeared to have less of an impact on the participant’s drinking outcomes. However, greater friends’ use of SHR strategies was associated with increased alcohol use by the participant, but not with consequences. Greater friends’ use of SHR strategies was associated with greater SHR strategy use by the participant. Friends’ LS and MD strategies were not associated with participant drinking, consequences, or PBS. These findings highlight the potential utility of interventions that focus on drinking behaviors on specific high-risk occasions for those at risk as well as for their friends. PMID:26114981

    The shift to use environmentally friendly technologies throughout future space-related launch programs prompted a study aimed at replacing current petroleum and solvent-based Corrosion Preventive Compounds (CPCs) with environmentally friendly alternatives. The work in this paper focused on the identification and evaluation of environmentally friendly CPCs for use in protecting flight hardware and ground support equipment from atmospheric corrosion. The CPCs, while a temporary protective coating, must survive in the aggressive coastal marine environment that exists throughout the Kennedy Space Center, Florida. The different protection behaviors of fifteen different soft film CPCs, both common petroleum-based and newer environmentally friendly types, were evaluated on various steel and aluminum substrates. The CPC and substrate systems were subjected to atmospheric testing at the Kennedy Space Center's Beachside Atmospheric Corrosion Test Site, as well as cyclic accelerated corrosion testing. Each CPC also underwent physical characterization and launch-related compatibility testing . The initial results for the fifteen CPC systems are reported : Key words: corrosion preventive compound, CPC, spaceport, environmentally friendly, atmospheric exposure, marine, carbon steel, aluminum alloy, galvanic corrosion, wire on bolt.

    The current study examined between- and within-person processes related to friendship intimacy, close-friend substance use, negative affect, and self-medication. We tested between-person hypotheses that global negative affect, friendship intimacy, and close-friend drug use predict increased substance use, and the within-person hypothesis that friendship intimacy and close-friend substance use moderate the temporal relationship between daily negative affect and subsequent substance use (i.e., self-medication). Experience sampling methodology (ESM) was employed to capture daily variations in mood and substance use, and multilevel modeling techniques were used to parse between- versus within-person differences in risk for use. Findings supported between-person hypotheses that higher levels of negative affect and lower levels of friendship intimacy predicted greater substance use, and a consistent trend indicated that friendship intimacy and close-friend drug use interact to predict substance use more generally (though not for self-medication). Risk and protective mechanisms emerged from this interaction such that the effect of friendship intimacy on adolescent use depends on the degree of close-friend drug use. More specific reformulations of the risk processes involving friendships and self-medication among younger youth are indicated.

    Full Text Available Consumers have increasing, but highly variable, interest in sustainability attributes of food, including ethical aspects, such as animal welfare. We explored market opportunities for animal-friendly cow’s milk based on segmentation (cluster analysis. Flemish survey participants (n = 787 were clustered (n = 6 based on their intention to purchase (IP animal-friendly milk, and their evaluation of cows’ welfare state (EV. Three market opportunity segments were derived from clusters and labelled as “high”, “moderate” and “limited”. Only 8% of the participants belong to the “high market opportunities” segment, characterized by a high IP and a low EV. The “limited” segment (44% indicated a neutral to low IP and a positive EV. The “moderate” segment (48% had a moderately positive IP and positive/negative EV. Reported willingness to pay, interest in information about the state of animal welfare and importance of the product attribute “animal welfare” differed among segments and were strongly related to IP. Most promising selling propositions about animal-friendly milk were related to pasture access. The high degree of differentiation within the Flemish milk market reveals market opportunities for animal-friendly milk, but for an effective market share increase supply of animal-friendly products needs to get more aligned with the heterogeneous demand.

    Although the majority of our social interactions are with people we know, few studies have investigated the neural correlates of sharing valuable resources with familiar others. Using an ecologically valid research paradigm, this functional magnetic resonance imaging study examined the neural correlates of prosocial and selfish behavior in interactions with real-life friends and disliked peers in young adults. Participants (N = 27) distributed coins between themselves and another person, where they could make selfish choices that maximized their own gains or prosocial choices that maximized outcomes of the other. Participants were more prosocial toward friends and more selfish toward disliked peers. Individual prosociality levels toward friends were associated negatively with supplementary motor area and anterior insula activity. Further preliminary analyses showed that prosocial decisions involving friends were associated with heightened activity in the bilateral posterior temporoparietal junction, and selfish decisions involving disliked peers were associated with heightened superior temporal sulcus activity, which are brain regions consistently shown to be involved in mentalizing and perspective taking in prior studies. Further, activation of the putamen was observed during prosocial choices involving friends and selfish choices involving disliked peers. These findings provide insights into the modulation of neural processes that underlie prosocial behavior as a function of a positive or negative relationship with the interaction partner.

    Parent and friend influences may differentially promote or deter adolescent smoking at discrete stages. Drawing from national (Add Health) data, a partial proportional odds ordinal regression model was utilized to examine the multivariate influence of parent and friend variables and their interactions on transitions across smoking stages (Never Smokers, Experimenters, Intermittent, Regular/Established) separately for mother-child pairs (N = 15,983) and father-child pairs (N = 1,142). Friend smoking status was by far the strongest predictor across smoking stages. Gender differences indicated males with one or more daily smoking friends are at higher risk for regular smoking relative to females. Fathers' smoking status had a direct effect on teen smoking across all stages, whereas mothers' smoking was significant in influencing which stage of smoking teens exhibited. Moreover, maternal smoking status had an indirect effect by moderating the association between teen smoking and the closeness of the mother-teen relationship. Mothers who smoke were found to have a stronger impact on the transition to regular smoking compared to mothers who do not smoke regardless of the number of smoking friends the teen reports. Results have implications for stage-matched and family-based prevention and intervention programs.

    2012-07-01

    Successful management of a complex disease, such as cystic fibrosis (CF), requires support from family and friends; however, few studies have examined social support in adolescents with CF. Twenty-four adolescents were interviewed about the support they receive from family and friends. Interviews were transcribed, coded and analysed to determine the types, frequency and perceived supportiveness of specific behaviours. Both family and friends provided treatment-related support to adolescents with CF. Family provided more tangible support and friends provided more relational support. Adolescents also reported that the manner, timing and context of support behaviours influenced their perceptions of the behaviours' supportiveness. A subset of adolescents (17%) chose not to disclose their diagnosis to their friends. The provision of support appears to be distinct from adolescent's perception of support and there may be some behaviours, such as treatment reminders, that are important to disease management but viewed as less supportive by adolescents. Facilitating increased social support holds the promise of improving disease management during adolescents, but more work is need to understand which aspects of support are related to management outcomes. © 2011 Blackwell Publishing Ltd.

    The school environment is extremely salient in young adolescents' lives. Adolescents who have unfavorable attitudes toward school and teachers are at elevated risk for dropping out of school and engaging in behavioral health risks. Peer network health-a summation of the positive and negative behaviors in which one's close friend group engages-may be one way by which attitudes toward school exert influence on youth substance use. Utilizing a sample of 248 primarily African-American young urban adolescents, we tested a moderated mediation model to determine if the indirect effect of attitude to school on cannabis involvement through peer network health was conditioned on gender. Attitude toward school measured at baseline was the predictor (X), peer network health measured at 6 months was the mediator (M), cannabis involvement (including use, offers to use, and refusals to use) measured at 24 months was the outcome (Y), and gender was the moderator (W). Results indicated that negative attitudes toward school were indirectly associated with increased cannabis involvement through peer network health. This relationship was not moderated by gender. Adolescents in our sample with negative attitudes toward school were more likely to receive more offers to use cannabis and to use cannabis more frequently through the perceived health behaviors of their close friends. Implications from these results point to opportunities to leverage the dynamic associations among school experiences, friends, and cannabis involvement, such as offers and use.

    In this study, we examined the content of adolescents' conversations with their friends about substance use, adolescents' reactions to such conversations, and reasons why some adolescents did not engage in such conversations. Based on 25 semistructured interviews with high school students, we identified three themes: informational, persuasive, and relational messages. Informational messages included discussing how many peers use substances and clarifying rumors about a friend's substance use. Persuasive messages involved direct anti-substance-use messages (e.g., warning), direct pro-substance-use messages (e.g., legalizing marijuana), indirect anti-substance-use messages (e.g., disliking their substance-use experience), and indirect pro-substance-use messages (e.g., intentions to use substances). Relational messages included joking about substance use and establishing code words for use. Adolescents reacted to their conversations in several ways, such as shock and increased relational closeness. When adolescents did not talk about substance use with their friend, they offered several reasons, including low response efficacy and fear of ruining the friendship.

    Dentistry is most importantly and foremost a healing profession. In today's world, it is very necessary to understand the importance of being eco-friendly in every facet of our lives, including dental practice which has a huge impact on the environment due to the large amount of metallic waste generated by various dental procedures along with excessive use of water and electricity, which specifically emphasis the thrust to move towards 'Green dentistry'. Green dentistry is an innovative way of dental practice which is environment friendly and at the same time conserves money and time by reducing waste, conserving energy and decreasing pollution with the use of latest techniques and procedures. Green dentistry therefore, protects the environment and mankind from the hazards of rapid urbanisation in developing countries. The authors wish to emphasize the practice of eco-friendly, green dentistry in a developing country like India which needs to conserve resources and curb environmental pollution.

    The aim of this study was to investigate the consequences of friend networking sites (e.g., Friendster, MySpace) for adolescents' self-esteem and well-being. We conducted a survey among 881 adolescents (10-19-year-olds) who had an online profile on a Dutch friend networking site. Using structural equation modeling, we found that the frequency with which adolescents used the site had an indirect effect on their social self-esteem and well-being. The use of the friend networking site stimulated the number of relationships formed on the site, the frequency with which adolescents received feedback on their profiles, and the tone (i.e., positive vs. negative) of this feedback. Positive feedback on the profiles enhanced adolescents' social self-esteem and well-being, whereas negative feedback decreased their self-esteem and well-being.

    In this study, the prevailing view that girls are pervasively more skilled in their friendships than boys was challenged by examining whether girls respond more negatively than boys when a friend violates core friendship expectations. Fourth- and fifth-grade children (n = 267) responded to vignettes depicting transgressions involving a friend's betrayal, unreliability, or failure to provide support or help. Results indicated that girls were more troubled by the transgressions, more strongly endorsed various types of negative relationship interpretations of the friend's actions, and reported more anger and sadness than did boys. Girls also endorsed revenge goals and aggressive strategies just as much as boys. These findings lead to a more complex view of boys' and girls' friendship competencies. © 2011 The Authors.

    Companions are central to explanations of the risky nature of unstructured and unsupervised socializing, yet we know little about whom adolescents are with when hanging out. We examine predictors of how often friendship dyads hang out via multilevel analyses of longitudinal friendship-level data on over 5,000 middle schoolers. Adolescents hang out most with their most available friends and their most generally similar friends, not with their most at-risk or similarly at-risk friends. These findings vary little by gender and wave. Together, the findings suggest that the risks of hanging out stem from the nature of hanging out as an activity, not the nature of adolescents’ companions, and that hanging out is a context for friends’ mutual reinforcement of pre-existing characteristics.

    Developing environments responsive to the aspirations of older people has become a major concern for social and public policy. Policies and programs directed at achieving "age-friendly" communities are considered to require a wide range of interventions, including actions at the level of the social and physical environment. This article compares the age-friendly approaches of two European cities, Brussels and Manchester, with a particular focus on policies and initiatives that promote active aging in an urban context. The article examines, first, the demographic, social, and multicultural contexts of Brussels and Manchester; second, the way in which both cities became members of the World Health Organization Global Network of Age-Friendly Cities and Communities; third, similarities and differences in the age-friendly approaches and actions adopted by both cities; and fourth, opportunities and barriers to the implementation of age-friendly policies. The article concludes by discussing the key elements and resources needed to develop age-friendly cities.

    Simple Summary This article takes a future focus on the direction in which social forces develop the market for animal-friendly products in Europe. Although many stakeholders believe that the market is the most viable direction to improve farm animal welfare, economic productivity of the chain remains an issue that on a fundamental level conflicts with the objective to improve animal welfare. The European market for animal-friendly products is still largely fragmented and the differences between European countries are considerable. A more animal-friendly future that is achieved through the market will therefore need substantial policy attention from stakeholders in society. Abstract This article takes a future focus on the direction in which social forces develop the market for animal-friendly products in Europe. On the basis of qualitative data gathered in the context of the European EconWelfare project, the differences across eight European countries are studied. The findings suggest that, given international trade barriers that prevent an improvement of animal welfare through legislation, many stakeholders believe that the market is the most viable direction to improve farm animal welfare. Economic productivity of the chain remains, however, an issue that on a fundamental level conflicts with the objective to improve animal welfare. With the help of a deeper conceptual understanding of willingness to pay for animal welfare, the paper finds that the European market for animal-friendly products is still largely fragmented and that the differences between European countries are considerable. A more animal-friendly future that is achieved through the market will therefore need substantial policy attention from stakeholders in society. PMID:26479535

  6. Is baby-friendly breastfeeding support in maternity hospitals associated with breastfeeding satisfaction among Japanese mothers?

    While the World Health Organization's Baby-Friendly Hospital Initiative has increased breastfeeding duration and exclusivity, a survey found that only 8.5 % of maternity hospitals in 31 developed countries could be designated baby-friendly. Baby-friendly breastfeeding support is sometimes criticized as mother unfriendly. This study examined whether baby-friendly breastfeeding support was associated with breastfeeding satisfaction, duration, and exclusivity among Japanese mothers. In this cross-sectional study, 601 breastfeeding Japanese mothers completed questionnaires at their infants' 4-month health checkups at two wards in Yokohama, Japan; 363 were included in the analysis. Baby-friendly breastfeeding support was measured based on the WHO's "Ten Steps to Successful Breastfeeding." We measured satisfaction using two subscales of the Japanese version of the Maternal Breastfeeding Evaluation Scale. The association of baby-friendly support with maternal satisfaction was assessed using multiple linear regression, while the prevalence ratios (PRs) for breastfeeding were estimated using Poisson regression. Mothers were stratified by prepartum exclusive breastfeeding intention (yes, n = 256; no, n = 107). Mothers who experienced early skin-to-skin contact with their infants were more likely to report breastfeeding satisfaction than those who did not. Among mothers without exclusive breastfeeding intention, those who were encouraged to feed on demand were more likely to be breastfeeding without formula at 1 month (PR 2.66 [95 % CI 1.32, 5.36]) and to perceive breastfeeding as beneficial for their baby (regression coefficient = 3.14 [95 % CI 0.11, 6.17]) than those who were not so encouraged. Breastfeeding satisfaction was a useful measure of breastfeeding outcome. Early skin-to-skin contact and encouragement to feed on demand in the hospital facilitate breastfeeding satisfaction.

  7. Anticipating Early Fatality: Friends', Schoolmates' and Individual Perceptions of Fatality on Adolescent Risk Behaviors

    Soller, Brian; Williams, Kristi

    2015-01-01

    Past research indicates that anticipating adverse outcomes, such as early death (fatalism), is associated positively with adolescents' likelihood of engaging in risky behaviors. Health researchers and criminologists have argued that fatalism influences present risk taking in part by informing individuals' motivation for delaying gratification for the promise of future benefits. While past findings highlight the association between the anticipation of early death and a number of developmental outcomes, no known research has assessed the impact of location in a context characterized by high perceptions of fatality. Using data from Add Health and a sample of 9,584 adolescents (51 % female and 71 % white) nested in 113 schools, our study builds upon prior research by examining the association between friends', school mates', and individual perceptions of early fatality and adolescent risk behaviors. We test whether friends' anticipation of being killed prior to age 21 or location in a school where a high proportion of the student body subscribes to attitudes of high fatality, is associated with risky behaviors. Results indicate that friends' fatalism is positively associated with engaging in violent delinquency, non-violent delinquency, and drug use after controlling for individual covariates and prior individual risk-taking. Although friends' delinquency accounts for much of the effect of friends' fatalism on violence, none of the potential intervening variables fully explain the effect of friends' fatalism on youth involvement in nonviolent delinquency and drug use. Our results underscore the importance of friendship contextual effects in shaping adolescent risk-taking behavior and the very serious consequences perceptions of fatality have for adolescents' involvement in delinquency and drug use.

    Twenty-first birthdays are associated with heavier drinking and more negative consequences than any other high-risk drinking event. Friends are the strongest social influence on young adult drinking; however, previous research on college students' drinking has often only examined individuals' perceptions of "friends" generally. Unfortunately, this may obscure the positive influence of some friends and the negative influence of others. Using data drawn from a larger intervention study aimed at reducing 21st birthday drinking, this research examined how specific friends (N = 166) who were present at 21st birthday celebrations may have exacerbated or mitigated celebrants' (N = 166) experience of alcohol-related consequences, as well as how characteristics of that friendship moderate these effects. Controlling for sex, alcohol consumption, and friend prointoxication intentions for the celebrants' 21st birthday drinking, higher friend prosafety/support intentions predicted the celebrants experiencing fewer alcohol-related consequences. Higher prosafety/support intentions also buffered participants from the negative influence of friend prointoxication intentions. Furthermore, the closeness of the friendship moderated this effect. At high levels of closeness, having a friend with lower prosafety/support intentions was associated with more alcohol-related consequences for the celebrant. Post hoc analyses revealed that this effect may have been driven by discrepancies between celebrants' and friends' reports of friendship closeness; celebrants' perception of closeness that was higher than the friends' perception was associated with the celebrant experiencing more alcohol-related consequences. Results demonstrate the ways that specific friends can both mitigate and exacerbate 21st birthday alcohol-related consequences. The implications of the present findings for incorporating specific friends into drinking-related interventions are discussed. (PsycINFO Database Record (c

    Full Text Available In this article, environmental-friendly finishing of wool fabric were processed with several water extract plants, such as hibiscus, St. John's wort, and marigold. The plant extracts have good basis in the commercial dyeing of wool, for garment and carpet industry. At the same time, the environmental-friendly finishing by water extracts plants shows very good fastness of the antimicrobial properties and coloration of wool fabric. From an ecological viewpoint, the substitution of chemical dyes with "natural products" may represent not only a strategy to reduce risk and pollutants but also an opportunity for new markets and new businesses, which can expend involving of ecology in trade policy.

    The relationship between autobiographical memories and self is important in many theories. Promising recent approaches from cross-cultural psychology use a concept of “self-construal”, in which reference to others can be as important as indicators of autonomy. However, these studies typically ask...... also most frequently on their mind. Furthermore, family memories referred most to other people, friend memories marginally less and school memories least, suggesting different contributions of these settings to self-construal. We conclude that characteristics of adolescents’ meaningful memories reflect...... shifting settings’ dominance during development and complementary roles of family, school and friends for adolescents’ current self-construal....

    Aging is an inevitable part of life. One can maintain well-being and wellness even after discharge and/or transition if his or her functional decline is minimized, sudden decline is prevented, and functioning is promoted during hospitalization. Caring appropriately for elderly patients requires the systematic application of Senior-Friendly Hospital principles to all operating systems, including medical centres' organization and environment, as well as patient treatment processes. The Senior-Friendly Hospital framework is valid and important for patient safety and quality improvement. This study aimed to make recommendations regarding the development of the Korean Framework for Senior-Friendly Hospitals for older patients' care management, patient safety interventions, and health promotion, via a Delphi survey. Two rounds of Delphi surveying were conducted with 15 participants who had at least 3 years' experience in accreditation surveying and medical accreditation standards, survey methods, and accreditation investigator education. In each round, we calculated statistics describing each standard's validity and feasibility. The Korean Framework for Senior-Friendly Hospitals included 4 Chapters, 11 categories, and 67 standards through consensus of the Senior-Friendly Hospitals task force and experts' peer review. After the two rounds of Delphi surveying, validity evaluation led to no changes in standards of the Senior-Friendly Hospitals; however, the number of standards showing adequate validity decreased from 67 to 58. Regarding feasibility, no changes were necessary in the standards; however, the number of categories showing adequate feasibility decreased from 11 to 8 and from 67 to 30, respectively. The excluded categories were 3.2, 4.2, and 4.3 (service, transportation, and signage and identification). The highest feasibility values were given to standards 2.1.1, 4.1.4, and 4.1.6. The highest feasibility score was given to standard 2.4.2. The Korean Framework for

    Full Text Available Online friend recommendation is a fast developing topic in web mining. In this paper, we used SVD matrix factorization to model user and item feature vector and used stochastic gradient descent to amend parameter and improve accuracy. To tackle cold start problem and data sparsity, we used KNN model to influence user feature vector. At the same time, we used graph theory to partition communities with fairly low time and space complexity. What is more, matrix factorization can combine online and offline recommendation. Experiments showed that the hybrid recommendation algorithm is able to recommend online friends with good accuracy.

    Objective Binge eating is prevalent among adolescents, but little is known about how parents and friends may influence such behaviors. This study examined associations between adolescent binge eating behaviors, and similar behaviors in their parents and friends. Method Participants were 2,770 target adolescent boys and girls who had at least one friend and/or parent who also participated. Logistic regression, stratified by gender, examined associations between parents’ and friends’ self-reported binge eating, and similar behaviors in target adolescents. Results Girls’ binge eating was associated with their male friends’ (odds ratio=2.33; p=.03) and fathers’ binge eating (odds ratio=3.38; p=.02), but not with their female friends’ or mothers’ binge eating (p>.05). For boys, binge eating was not associated with parents’ or friends’ behavior. Discussion Adolescent girls’ binge eating is associated with similar behaviors in their other-sex parents and friends. Results should be replicated, and mechanisms explaining this relation should be further explored. PMID:24105696

    Drawing from social comparison theory, we examine how perceptions of friends’ body sizes may influence adolescents’ subjective evaluations of their own body (e.g., how accurate they are in judging their weight, how much body dissatisfaction they feel), particularly for adolescent females. Participants were low-income, minority adolescents (Study 1: N = 194 females, Mean age = 15.4; Study 2: N = 409 males and females; Mean age = 14.9). Adolescents used figure rating scales to indicate their perceived size and that of four of their closest friends and completed several measures of subjective weight evaluation (e.g., weight classification, body dissatisfaction, internalized weight bias). In both studies, how adolescents perceived their body size and the body sizes of their thinnest and heaviest friends were positively correlated. In Study 1, overweight females based on measured BMI were less likely to accurately judge themselves as overweight if they had a close friend they perceived as heavy. In addition, females who viewed themselves as having a larger figure reported more internalized weight bias when they had friends they viewed as relatively thin. Findings from Study 2 suggest that how friends’ bodies are perceived is predictive of subjective weight evaluation measures only for adolescent females. Programs that address negative aspects of social comparison may be important in preventing both obesity and eating disorder symptoms in adolescent females. PMID:26403505

    Full Text Available Physical layer security is an emerging security area that achieves perfect secrecy data transmission between intended network nodes, while malicious nodes that eavesdrop the communication obtain zero information. The so-called secrecy capacity can be improved using friendly jammers that introduce extra interference to the eavesdroppers. We investigate the interaction between the source that transmits the useful data and friendly jammers who assist the source by "masking" the eavesdropper. To obtain distributed solution, we introduce a game theoretic approach. The game is defined such that the source pays the jammers to interfere the eavesdropper, therefore, increasing the secrecy capacity. The friendly jammers charge the source with a certain price for the jamming, and there is a tradeoff for the price. If too low, the profit of the jammers is low; and if too high, the source would not buy the "service" (jamming power or would buy it from other jammers. To analyze the game outcome, we investigate a Stackelburg type of game and construct a distributed algorithm. Our analysis and simulation results show the effectiveness of friendly jamming and the tradeoff for setting the price. The distributed game solution is shown to have similar performances to those of the centralized one.

    2012-01-01

    Involvement with friends carries many advantages for adolescents, including protection from the detrimental effects of being rejected by peers. However, little is known about the mechanisms through which friendships may serve their protective role at this age, or the potential benefit of these friendships as adolescents transition to adulthood. As such, this investigation tested whether friend involvement during adolescence related to less neural sensitivity to social threats during young adulthood. Twenty-one adolescents reported the amount of time they spent with friends outside of school using a daily diary. Two years later they underwent an fMRI scan, during which they were ostensibly excluded from an online ball-tossing game by two same-age peers. Findings from region of interest and whole brain analyses revealed that spending more time with friends during adolescence related to less activity in the dorsal anterior cingulate cortex and anterior insula--regions previously linked with negative affect and pain processing--during an experience of peer rejection 2 years later. These findings are consistent with the notion that positive relationships during adolescence may relate to individuals being less sensitive to negative social experiences later on.

    2018-01-01

    The present study examines the short-term changes and longitudinal relations between adolescents' materialism and prosocial behavior toward family, friends, and strangers over a year. A total of 434 Chinese adolescents (mean age at Time 1 = 11.27; 54% girls) participated in the two time points. From 6 th grade to 7 th grade, boys' and girls' materialism increased, whereas their prosocial behavior toward family, friends, and strangers declined, despite the stable trend in boys' prosocial behavior toward strangers. Furthermore, a cross-lagged model was conducted and the results showed that, adolescent materialism was associated longitudinally with decreased prosocial behavior toward friends and strangers, but not toward family. However, earlier prosocial behavior toward family, friends, and strangers were not associated with subsequent adolescent materialism. The findings point toward an understanding of materialism as a precursor rather than an outcome or byproduct to prosocial behavior.

  7. Implementing the Critical Friend Method for Peer Feedback among Teaching Librarians

    Directory of Open Access Journals (Sweden)

    Yvonne Hultman Özek

    2012-12-01

    Full Text Available Objective – The role of the academic librarian has become increasingly educative innature. In this study, the critical friend method was introduced among teachinglibrarians in an academic setting of medicine and health sciences to ascertainwhether this approach could be implemented for feedback on teaching of theselibrarians as part of their professional development.Methods – We used a single intrinsic case study. Seven teaching librarians and one educator from the faculty of medicine participated, and they all provided and received feedback. These eight teachers worked in pairs, and each of them gave at least one lecture or seminar during the study period. The performance of one teacher and the associated classroom activities were observed by the critical friend and then evaluated and discussed. The outcome and effects of critical friendship were assessed by use of a questionnaire.Results – The present results suggest that use of the critical friend method among teaching academic librarians can have a positive impact by achieving the following: strengthening shared values concerning teaching issues; promoting self-reflection, which can improve teaching; facilitating communication with colleagues; and reducing the sense of “loneliness” in teaching. This conclusion is also supported by the findings of previous studies.Conclusion – The critical friend method described in this study can easily be implemented and developed among teaching librarians, provided that there is support from the organization. This will benefit the individual teaching librarian, as well as the organization at large.

    Cleveland, H Harrington; Wiebe, Richard P; Rowe, David C

    2005-06-01

    Substance-using friends expose adolescents to models of, and opportunities for, substance use that may lead to its initiation or reinforce existing use. Using genetically informative data from the National Longitudinal Study of Adolescent Health (P. S. Bearman, J. Jones, & J. R. Udry, 1998), the authors examined whether adolescents' exposure to friends' tobacco smoking and alcohol drinking was better explained by family-social or genetic influences. To conduct analyses, the authors constructed substance use exposure scores for adolescent siblings from the responses of siblings' nominated friends to self-reported smoking and drinking items. Using behavioral-genetic analyses of these substance use exposure scores, the authors estimated that 64% of the variance in adolescents' exposure to friends who smoke and drink could be explained by genetic influences, whereas shared environmental influences were zero. These results provide evidence of active, evocative, or both types of gene-environment correlations. Genetic factors can influence the formation of friendships with substance-using peers, thereby contributing to adolescents' exposure to substance use behaviors.

  5. Friends as a Bridge to Parental Influence: Implications for Adolescent Alcohol Use.

    Science.gov (United States)

    Ragan, Daniel T; Osgood, D Wayne; Feinberg, Mark E

    2014-01-01

    The current study investigates the possibility that friendship networks connect adolescents to influence from a broader group of adults beyond their own families. In doing so, we combine two rich traditions of research on adult influence on children and adolescents. Family research has suggested a number of ways in which effective parenting can reduce deviant behavior among adolescents. In addition, research on neighborhoods has advanced the idea that adults outside of the immediate family can exert social control that may reduce deviance. We employ longitudinal social network analysis to examine data drawn from the PROSPER Peers Project, a longitudinal study of adolescents following over 12,000 students in 27 non-metropolitan communities as they moved from 6th through 9th grade. We find evidence that the behavior of friends' parents is linked, both directly and indirectly, to adolescent alcohol use. Findings suggest that much of the influence from friends' parents is mediated through peer behavior, but that parental knowledge reported by friends continues to be associated with alcohol use even when controlling for competing mechanisms. Furthermore, adolescents tend to choose friends who report similar levels of parenting as themselves. Our results provide support for the position that friendships in adolescence connect youth to a broader network of adults and illustrate how adults outside of the family contribute to the social control of adolescents.

  11. Early Risk Factors for Alcohol Use Across High School and Its Covariation With Deviant Friends

    Armstrong, Jeffrey M.; Ruttle, Paula L.; Burk, Linnea R.; Costanzo, Philip R.; Strauman, Timothy J.; Essex, Marilyn J.

    2013-01-01

    Objective: Past research has associated childhood characteristics and experiences with alcohol use at single time points in adolescence. Other work has focused on drinking trajectories across adolescence but with risk factors typically no earlier than middle or high school. Similarly, although the connection between underage drinking and affiliation with deviant friends is well established, early risk factors for their covariation across adolescence are uncertain. The present study examines the influence of early individual and contextual factors on (a) trajectories across high school of per-occasion alcohol use and (b) the covariation of alcohol use and deviant friends over time. Method: In a longitudinal community sample (n = 374; 51% female), temperamental disinhibition, authoritarian and authoritative parenting, and parental alcohol use were assessed during childhood, and adolescents reported on alcohol use and affiliation with deviant friends in the spring of Grades 9, 10, 11, and 12. Results: Early parental alcohol use predicted the intercept of adolescent drinking. Subsequent patterns of adolescent alcohol use were predicted by sex and interactions of sex and childhood disinhibition with early authoritarian parenting. Additionally, childhood disinhibition interacted with parental alcohol use to moderate the covariation of drinking and deviant friends. Conclusions: These findings highlight early individual and contextual risk factors for alcohol use across high school, extending previous work and underscoring the importance of developmental approaches and longitudinal techniques for understanding patterns of growth in underage drinking.

  10. The Role of Friends Groups in the Development and management of Parks

    2008-07-01

    Full Text Available In the United Kingdom, community involvement in environmental design and management has become increasingly important and encouraged by government through grant schemes which require the participation of the local community. Many local authorities are now working with friends groups, which are voluntary groups for park development and management. In a study established to investigate the role of friends groups, it was found that such groups act not only as a supplier of resources, but they contribute to the broadening base of decision-making through the empowerment of the community. This study classifies friends groups into four main roles: a supplier of resources, b pressure group, c intermediary and d facilitator for empowerment of the community. Based on these classifications, a case study located in England's northeast is discussed. The catalyst of the action there was the resistance to proposed park change. Although the Friends of Leazes Park played all four roles during the restoration of the park, their present role is one of management restricted to the supplier of resources.

    Full Text Available The present paper stems from the evidence that one of the reasons of the “crisis” of today's cities probably depend on mobility issues.   But what should be done to confront all the negative impacts of passenger transportation, without curbing mobility? Can Urban Engineering be applied to promote a friendlier mobility, that should be not only environment and climate friendly, but user friendly as well? And how? A "people friendly" accessibility approach is presented and conceived as a solution to better integrate land uses with the transport system, satisfying people's expectations (especially those of vulnerable users to easily reach the opportunities they wish to engage with.  The case study of Amsterdam, as walkable and cycle friendly city, is briefly presented and reveal good practices in the field of urban and mobility planning.  Finally, an isochronical accessibility analysis of Amsterdam is applied: it represent catchment areas of railways stations and of supermarkets, and it highlights how much the structure of the city supports bicycle use.

  20. Perceptions of alcohol use by friends compared to peers: Associations with middle adolescents' own use.

    Beckmeyer, Jonathon J; Weybright, Elizabeth H

    2016-01-01

    In this study, the authors (a) distinguished between adolescents' perceptions of their peers' and friends' alcohol use to examine the unique associations these perceptions have on adolescents' own alcohol use and (b) tested if the ability to resist peer influence moderated those associations. Data were from the Study of Early Child Care and Youth Development (N = 876, all aged 15). Adolescents reported (a) perceptions of alcohol use by their peers, (b) perceptions of alcohol use by their friends, (c) their own alcohol use in the last year, and (d) a measure of their ability to resist peer influence. Data were analyzed with hierarchical logistic regression (HLR), controlling for demographic variables and parental knowledge. Three HLR models were computed: 1 for the full sample, 1 for only males, and 1 for only females. In all models, perceptions of alcohol use by friends (odds ratios [ORs]: OR Full = 10.17, OR Female = 15.51, OR Male = 7.25) were associated with a greater likelihood of adolescents using alcohol themselves. Perceptions of alcohol use by peers (OR Full = 1.13, OR Female = 1.11, OR Male = 1.14) were not significantly associated with adolescents' own alcohol use. The ability to resist peer influence did not moderate any of those associations. It appears that when adolescents perceive more of their friends, but not their peers, consume alcohol, they themselves are at greater risk for alcohol use, and those associations do not depend upon their ability to resist peer influence.

    Friendships play an important role in the development of school involvement and academic performance during adolescence. This study examined the interdependence of depressive symptoms, school involvement, and academic performance between adolescent same-sex friends. Using cross-sectional data, we examined whether the link between depressive symptoms and academic performance would be mediated by school involvement at the intrapersonal (actor) and interpersonal (partner) levels. Data came from 155 pairs of same-sex adolescent friends (80 boys; M(age) = 16.17, SD = 0.44). The actor-partner interdependence model was used to examine the dyadic data and mediation hypotheses. Mediated actor effects showed that adolescents who had more depressive symptoms reported lower academic performance, and such an association was mediated by their own and their friend's lower school involvement. Mediated partner effects showed that adolescents who had more depressive symptoms also had a friend with lower academic performance, and such an association was mediated by both individuals' lower school involvement. This study provided evidence to support the broader interpersonal framework for understanding school involvement and academic performance. The current findings also have potential practical implications, especially for programmes targeted at addressing adolescents' school problems. © 2015 The British Psychological Society.

    This study examines sociocultural influences affecting both body image and body change methods in adolescent boys. Twenty boys in grade 7 (aged 12-13) and twenty boys in grade 9 (aged 14-15) were individually interviewed. The influence of parents, siblings, friends and the media on both body image and body change methods was evaluated. For approximately a third of the boys, parents, siblings, friends and the media were perceived to have at least some influence over boys' feelings about their bodies and body change methods. In particular, feedback from mothers and female friends were viewed as having a positive impact on boys' body image whereas feed-back from fathers and male friends was viewed as more important in influencing body change methods. The media was also viewed as contributing to boys' body satisfaction but it was seen to encourage greater exercise to alter body size and shape. The differences and similarities between the sociocultural messages received by males and females are discussed. The implication of these findings in fostering better health among adolescent males are explored.

For the purpose of study the relationships with parents, friends and romantic partners we translated and adapted Inventory of parent and peer attachment IPPA (Armsden & Greenberg, 1987. Attachment styles were measured using their descriptions. We developed the scales of characteristics of the subjects' romantic relationships and openness towards their parents and partners. The results showed significant positive relations between subject's quality relationships with his/her partner, secure attachment style, and quality relationships with friends and parent. Subjects with different attachment styles significantly differed in the characteristics of their romantic relationships. The results showed some significant gender differences. Female subjects had more quality relationships with their mothers, friends and partners than male subjects.

    Armstrong, Jeffrey M; Ruttle, Paula L; Burk, Linnea R; Costanzo, Philip R; Strauman, Timothy J; Essex, Marilyn J

    Past research has associated childhood characteristics and experiences with alcohol use at single time points in adolescence. Other work has focused on drinking trajectories across adolescence but with risk factors typically no earlier than middle or high school. Similarly, although the connection between underage drinking and affiliation with deviant friends is well established, early risk factors for their covariation across adolescence are uncertain. The present study examines the influence of early individual and contextual factors on (a) trajectories across high school of per-occasion alcohol use and (b) the covariation of alcohol use and deviant friends over time. In a longitudinal community sample (n = 374; 51% female), temperamental disinhibition, authoritarian and authoritative parenting, and parental alcohol use were assessed during childhood, and adolescents reported on alcohol use and affiliation with deviant friends in the spring of Grades 9, 10, 11, and 12. Early parental alcohol use predicted the intercept of adolescent drinking. Subsequent patterns of adolescent alcohol use were predicted by sex and interactions of sex and childhood disinhibition with early authoritarian parenting. Additionally, childhood disinhibition interacted with parental alcohol use to moderate the covariation of drinking and deviant friends. These findings highlight early individual and contextual risk factors for alcohol use across high school, extending previous work and underscoring the importance of developmental approaches and longitudinal techniques for understanding patterns of growth in underage drinking.
