2003-04-01

We designed a questionnaire concerned with attitudes and behaviour towards organic foods, environmentally friendly behaviour (EFB), and perceived consequences of organic food choice in terms of human health, the environment and animal welfare. It was mailed in 1998 to a random nation-wide sample of 2000 Swedish citizens, ages 18-65 years, and 1154 (58%) responded. Self-reported purchase of organic foods was most strongly related to perceived benefit for human health. Performance of EFBs such as refraining from car driving was also a good predictor of purchase frequency. The results indicate that egoistic motives are better predictors of the purchase of organic foods than are altruistic motives.

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.

Intermediate peer contexts and educational outcomes: Do the friends of students' friends matter?

Carbonaro, William; Workman, Joseph

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.

Furman, Wyndol; Shaffer, Laura

2011-01-01

The purpose of the present study was to provide a detailed examination of sexual behavior with different types of partners. A sample of 163 young adults reported on their light nongenital, heavy nongenital, and genital sexual activity with romantic partners, friends, and casual acquaintances. They described their sexual activity with “friends with benefits” as well as with friends in general. Young adults were most likely to engage in sexual behavior with romantic partners, but sexual behavior also often occurred with some type of nonromantic partner. More young adults engaged in some form of sexual behavior with casual acquaintances than with friends with benefits. The frequencies of sexual behavior, however, were greater with friends with benefits than with friends or casual acquaintances. Interview and questionnaire data revealed that friends with benefits were typically friends, but not necessarily. Nonsexual activities were also less common with friends with benefits than other friends. Taken together, the findings illustrate the value of differentiating among different types of nonromantic partners and different levels of sexual behavior. PMID:21128155

Full Text Available A small bakery in regional Tasmania, Australia, has been reimagined as a pop culture destination by Japanese tourists who claim it is the inspiration for a key location in the anime Kiki's Delivery Service. To understand how and why Japanese tourists have located this bakery in the imaginary world of Kiki, two processes are explored: the media pilgrimage, where fans bridge their ordinary reality and enter the special media world, and the media scaffold, where Kiki becomes a way to interpret the world around them.

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

2015-05-01

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.

Distinguishing Family from Friends : Implicit Cognitive Differences Regarding General Dispositions, Attitude Similarity, and Group Membership.

Science.gov (United States)

O'Gorman, Rick; Roberts, Ruth

2017-09-01

Kinship and friendship are key human relationships. Increasingly, data suggest that people are not less altruistic toward friends than close kin. Some accounts suggest that psychologically we do not distinguish between them; countering this is evidence that kinship provides a unique explanatory factor. Using the Implicit Association Test, we examined how people implicitly think about close friends versus close kin in three contexts. In Experiment 1, we examined generic attitudinal dispositions toward friends and family. In Experiment 2, attitude similarity as a marker of family and friends was examined, and in Experiments 3 and 4, strength of in-group membership for family and friends was examined. Findings show that differences exist in implicit cognitive associations toward family and friends. There is some evidence that people hold more positive general dispositions toward friends, associate attitude similarity more with friends, consider family as more representative of the in-group than friends, but see friends as more in-group than distant kin.

Bauminger-Zviely, Nirit; Agam-Ben-Artzi, Galit

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.

2015-12-01

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.

Lewis, David M G; Conroy-Beam, Daniel; Al-Shawaf, Laith; Raja, Annia; DeKay, Todd; Buss, David M

2011-12-08

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 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.

Full Text Available Children and adults consistently match some words (e.g., kiki to jagged shapes and other words (e.g., bouba to rounded shapes, providing evidence for non-arbitrary sound–shape mapping. In this study, we investigated the influence of vowels on sound–shape matching in toddlers, using four contrasting pairs of nonsense words differing in vowel sound (/i/ as in feet vs. /o/ as in boat and four rounded–jagged shape pairs. Crucially, we used reduplicated syllables (e.g., kiki vs. koko rather than confounding vowel sound with consonant context and syllable variability (e.g., kiki vs. bouba. Toddlers consistently matched words with /o/ to rounded shapes and words with /i/ to jagged shapes (p < 0.01. The results suggest that there may be naturally biased correspondences between vowel sound and shape.

1996-01-01

We have developed a human friendly reporting and database system for clinical brain PET (Positron Emission Tomography) scans, which enables statistical data analysis on qualitative information obtained from image interpretation. Our system consists of a Brain PET Data (Input) Tool and Report Writing Tool. In the Brain PET Data Tool, findings and interpretations are input by selecting menu icons in a window panel instead of writing a free text. This method of input enables on-line data entry into and update of the database by means of pre-defined consistent words, which facilitates statistical data analysis. The Report Writing Tool generates a one page report of natural English sentences semi-automatically by using the above input information and the patient information obtained from our PET center's main database. It also has a keyword selection function from the report text so that we can save a set of keywords on the database for further analysis. By means of this system, we can store the data related to patient information and visual interpretation of the PET examination while writing clinical reports in daily work. The database files in our system can be accessed by means of commercially available databases. We have used the 4th Dimension database that runs on a Macintosh computer and analyzed 95 cases of 18 F-FDG brain PET studies. The results showed high specificity of parietal hypometabolism for Alzheimer's patients. (author)

This study assessed early adolescents' sexual communication with dating partners, parents, and best friends about six sexual health topics: condoms, birth control, sexually transmitted diseases (STDs), human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), pregnancy, and abstinence/waiting. Using a school-based sample of 603 youth (ages 12 to 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. More than 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.

From Family to Friends: Does Witnessing Interparental Violence Affect Young Adults’ Relationships with Friends?

Science.gov (United States)

Mandal, Mahua; Hindin, Michelle J.

2013-01-01

Purpose Childhood exposure to violence in one’s family of origin has been closely linked to subsequent perpetration and victimization of intimate partner violence. There is, however, little research on the relationship between witnessing violence and subsequent peer violence. This study investigates the effects of witnessing interparental violence among Filipino young adults on their use and experience of psychological aggression with friends. Methods The data source for this study was the Cebu Longitudinal Health and Nutrition Survey. Recent perpetration and victimization of friend psychological aggression among young adults ages 21–22 years was assessed through self-reports from the 2005 survey, and witnessing interparental violence during childhood was assessed through self-reports from the 2002 survey. Multinomial logistic regression was used to examine the effects of witnessing interparental violence on subsequent use and experience of friend psychological aggression. Analyses were stratified by gender. Results About 13% of females and 4% of males perpetrated psychological aggression towards close friends, and about 4% of females and males were victims. Fourteen percent of females and 3% of males experienced bidirectional psychological aggression. About 44% of females and 47% of males had, during childhood, witnessed their parents physically hurt one another. Witnessing maternal and reciprocal interparental violence during childhood significantly predicted bidirectional friend psychological aggression among males. Among females, witnessing interparental violence did not significantly predict involvement with friend psychological aggression. Conclusions Violence prevention programs should consider using family-centered interventions, and apply a gendered lens to their application. Further research on gender differences in friend aggression is recommended. PMID:23697789

Energetic consequences of human sociality: walking speed choices among friendly dyads.

Directory of Open Access Journals (Sweden)

Janelle Wagnild

Full Text Available Research has shown that individuals have an optimal walking speed-a speed which minimizes energy expenditure for a given distance. Because the optimal walking speed varies with mass and lower limb length, it also varies with sex, with males in any given population tending to have faster optimal walking speeds. This potentially creates an energetic dilemma for mixed-sex walking groups. Here we examine speed choices made by individuals of varying stature, mass, and sex walking together. Individuals (N = 22 walked around a track alone, with a significant other (with and without holding hands, and with friends of the same and opposite sex while their speeds were recorded every 100 m. Our findings show that males walk at a significantly slower pace to match the females' paces (p = 0.009, when the female is their romantic partner. The paces of friends of either same or mixed sex walking together did not significantly change (p>0.05. Thus significant pace adjustment appears to be limited to romantic partners. These findings have implications for both mobility and reproductive strategies of groups. Because the male carries the energetic burden by adjusting his pace (slowing down 7%, the female is spared the potentially increased caloric cost required to walk together. In energetically demanding environments, we will expect to find gender segregation in group composition, particularly when travelling longer distances.

Best friends' interactions and substance use: The role of friend pressure and unsupervised co-deviancy.

Tsakpinoglou, Florence; Poulin, François

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.

Adoptive immunotherapy is a highly effective strategy for treating many human cancers, such as melanoma, cervical cancer, lymphoma, and leukemia. Here, a novel cell culture technology is reported for expanding primary human T cells for adoptive immunotherapy. T cells are suspended and cultured in microscale alginate hydrogel tubes (AlgTubes) that are suspended in the cell culture medium in a culture vessel. The hydrogel tubes protect cells from hydrodynamic stresses and confine the cell mass less than 400 µm (in radial diameter) to ensure efficient mass transport, creating a cell-friendly microenvironment for growing T cells. This system is simple, scalable, highly efficient, defined, cost-effective, and compatible with current good manufacturing practices. Under optimized culture conditions, the AlgTubes enable culturing T cells with high cell viability, low DNA damage, high growth rate (≈320-fold expansion over 14 days), high purity (≈98% CD3+), and high yield (≈3.2 × 10 8 cells mL -1 hydrogel). All offer considerable advantages compared to current T cell culturing approaches. This new culture technology can significantly reduce the culture volume, time, and cost, while increasing the production. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Vyacheslav Vasilevich (V.V.) Klimov (or Slava, as most of us called him) was born on January 12, 1945 and passed away on May 9, 2017. He began his scientific career at the Bach Institute of Biochemistry of the USSR Academy of Sciences (Akademy Nauk (AN) SSSR), Moscow, Russia, and then, he was associated with the Institute of Photosynthesis, Pushchino, Moscow Region, for about 50 years. He worked in the field of biochemistry and biophysics of photosynthesis. He is known for his studies on the molecular organization of photosystem II (PSII). He was an eminent scientist in the field of photobiology, a well-respected professor, and, above all, an outstanding researcher. Further, he was one of the founding members of the Institute of Photosynthesis in Pushchino, Russia. To most, Slava Klimov was a great human being. He was one of the pioneers of research on the understanding of the mechanism of light energy conversion and of water oxidation in photosynthesis. Slava had many collaborations all over the world, and he is (and will be) very much missed by the scientific community and friends in Russia as well as around the World. We present here a brief biography and some comments on his research in photosynthesis. We remember him as a friendly and enthusiastic person who had an unflagging curiosity and energy to conduct outstanding research in many aspects of photosynthesis, especially that related to PSII.

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.

Shaking Takete and Flowing Maluma. Non-Sense Words Are Associated with Motion Patterns.

Full Text Available People assign the artificial words takete and kiki to spiky, angular figures and the artificial words maluma and bouba to rounded figures. We examined whether such a cross-modal correspondence could also be found for human body motion. We transferred the body movements of speakers onto two-dimensional coordinates and created animated stick-figures based on this data. Then we invited people to judge these stimuli using the words takete-maluma, bouba-kiki, and several verbal descriptors that served as measures of angularity/smoothness. In addition to this we extracted the quantity of motion, the velocity of motion and the average angle between motion vectors from the coordinate data. Judgments of takete (and kiki were related to verbal descriptors of angularity, a high quantity of motion, high velocity and sharper angles. Judgments of maluma (or bouba were related to smooth movements, a low velocity, a lower quantity of motion and blunter angles. A forced-choice experiment during which we presented subsets with low and high rankers on our motion measures revealed that people preferably assigned stimuli displaying fast movements with sharp angles in motion vectors to takete and stimuli displaying slow movements with blunter angles in motion vectors to maluma. Results indicated that body movements share features with information inherent in words such as takete and maluma and that people perceive the body movements of speakers on the level of changes in motion direction (e.g., body moves to the left and then back to the right. Follow-up studies are needed to clarify whether impressions of angularity and smoothness have similar communicative values across different modalities and how this affects social judgments and person perception.

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

Risk benefits of climate-friendly energy supply options

Hirschberg, S.; Burgherr, P.

2003-01-01

One of the central goals of sustainable development is the reduction of Greenhouse Gas (GHG) emissions. This is needed in order to prevent the anticipated climate change, and the potentially serious consequences for human beings and the environment. Energy supply systems constitute the dominant contributors to GHG emissions. This paper examines three illustrative emission scenarios for world-wide energy supply in the 21 st Century. These scenarios, including the associated GHG and major pollutant emissions, were chosen from a set established by the Intergovernmental Panel on Climate Change (IPCC). Using the emissions as a starting point, and based on recent findings concerning the impact on the environment and the financial costs resulting from global climate change on the one hand, and regional air pollution on the other hand, the present work provides estimates of the scenario-dependent, world-wide cumulative damage. The fossil-intensive reference scenario leads to overall damages which correspond to very substantial losses in Gross Domestic Product (GDP), and which widely exceed the damages caused by the scenarios reflecting climate-friendly policies. Generally, the somewhat speculative estimates of the GHG-specific damages are much less significant than damages to human health and the environment caused by the major air pollutants. This means that the secondary benefits of climate-friendly, energy-supply options, i.e. those which avoid the impacts due to air pollution, alone justify strategies protecting the climate. (author)

Critical friends and collaborative partnership

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.

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.

To assess faculty perceptions of professional boundaries and trainee-posted content on social networking sites (SNS). In June 2010, the Clerkship Directors in Internal Medicine conducted its annual survey of U.S. and Canadian member institutions. The survey included sections on demographics and social networking. The authors used descriptive statistics and tests of association to analyze the Likert scale responses and qualitatively analyzed the free-text responses. Of 110 institutional members, 82 (75%) responded to the survey. Of the 40 respondents who reported current or past SNS use, 21 (53%) reported receiving a "friend request" from a current student and 25 (63%) from a current resident. Of these, 4 (19%) accepted the student request and 12 (48%) accepted the resident request. Sixty-three of 80 (79%) felt it was inappropriate to send a friend request to a current student, 61 (76%) to accept a current student's request, 42 (53%) to become friends with a current resident, and 61 (81%) to become friends with a current patient. Becoming friends with a former student, former resident, or colleague was perceived as more appropriate. Younger respondents were less likely to deem specific student behaviors inappropriate (odds ratio [OR] 0.18-0.79; adjusted OR 0.12-0.86, controlling for respondents' sex, rank, and SNS use), although none reached statistical significance. Some internal medicine educators are using SNSs and interacting with trainees online. Their perceptions on the appropriateness of social networking behaviors provide some consensus for professional boundaries between faculty and trainees in the digital world.

It is accepted that newborns lose weight in the first few days of life. Baby-Friendly practices that support breastfeeding may affect newborn weight loss. The objective of this study were: 1) To determine whether Baby-Friendly practices are associated with term newborn weight loss day 0-2 in three feeding categories (exclusively breastfed, mixed formula fed and breastfed, and formula fed). 2) To determine whether Baby-Friendly practices increase exclusive breast feeding rates in different ethnic populations. This was a retrospective case-control study. Term newborn birth weight, neonatal weights days 0-2, feeding type, type of birth, and demographic information were collected for 1,000 births for the year before Baby-Friendly designation (2010) and 1,000 in 2013 (after designation). Ultimately 683 in the first group and 518 in the second met the inclusion criteria. Mean weight loss decreased day 0-2 for infants in all feeding types after the initiation of Baby-Friendly practices. There was a statistically significant effect of Baby-Friendly designation on weight loss for day 0-2 in exclusively breastfed infants (p Baby-Friendly practices were put in place. There was a decrease in mean weight loss day 0-2 regardless of feeding type after Baby-Friendly designation. Exclusive breast feeding increased in the presence of Baby-Friendly practices.

Miriam Mbasera

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.

In this study, we videotaped two 10-min. free-play interactions and coded speech acts (SAs) in peer talk of 51 preschoolers (21 ASD, 30 typical), interacting with friend versus non-friend partners. Groups were matched for maternal education, IQ (verbal/nonverbal), and CA. We compared SAs by group (ASD/typical), by partner's friendship status (friend/non-friend), and by partner's disability status. Main results yielded a higher amount and diversity of SAs in the typical than the ASD group (mainly in assertive acts, organizational devices, object-dubbing, and pretend-play); yet, those categories, among others, showed better performance with friends versus non-friends. Overall, a more nuanced perception of the pragmatic deficit in ASD should be adopted, highlighting friendship as an important context for children's development of SAs.

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.

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.

Influence of friends on children's physical activity: a review.

Science.gov (United States)

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.

When Sandpaper Is 'Kiki' and Satin Is 'Bouba': an Exploration of the Associations Between Words, Emotional States, and the Tactile Attributes of Everyday Materials.

Etzi, Roberta; Spence, Charles; Zampini, Massimiliano; Gallace, Alberto

2016-01-01

Over the last decade, scientists working on the topic of multisensory integration, as well as designers and marketers involved in trying to understand consumer behavior, have become increasingly interested in the non-arbitrary associations (e.g., sound symbolism) between different sensorial attributes of the stimuli they work with. Nevertheless, to date, little research in this area has investigated the presence of these crossmodal correspondences in the tactile evaluation of everyday materials. Here, we explore the presence and nature of the associations between tactile sensations, the sound of non-words, and people's emotional states. Samples of cotton, satin, tinfoil, sandpaper, and abrasive sponge, were stroked along the participants' forearm at the speed of 5 cm/s. Participants evaluated the materials along several dimensions, comprising scales anchored by pairs of non-words (e.g., Kiki/Bouba) and adjectives (e.g., ugly/beautiful). The results revealed that smoother textures were associated with non-words made up of round-shaped sounds (e.g., Maluma), whereas rougher textures were more strongly associated with sharp-transient sounds (e.g., Takete). The results also revealed the presence of a number of correspondences between tactile surfaces and adjectives related to visual and auditory attributes. For example, smooth textures were associated with features evoked by words such as 'bright' and 'quiet'; by contrast, the rougher textures were associated with adjectives such as 'dim' and 'loud'. The textures were also found to be associated with a number of emotional labels. Taken together, these results further our understanding of crossmodal correspondences involving the tactile modality and provide interesting insights in the applied field of design and marketing.

The authors evaluated the role parent-child relationship quality has on two types of memories, those of parents and those of friends. Participants were 198 Italian university students who recalled memories during 4 separate timed memory-fluency tasks about their preschool, elementary school, middle school, high school and university years. Half were instructed to recall memories involving parents and the remainder memories involving friends. Moreover, parent-child relationships were assessed by the Network of Relationships Inventory (NRI; W. Furman & D. Buhrmester, 1985) and Adolescents' Report of Parental Monitoring (D. M. Capaldi & G. R. Patterson, 1989). Results showed that men with positive parent-son relationships had more memories of parents and more affectively positive memories of friends, supporting a consistency model positing similarity between parent-child relationships and memories of friends. Women with positive parental relationship quality had more affectively positive memories of parents but for friends, positive relationship quality only predicted positive memories when young. At older ages, especially middle school-aged children, negative parent-daughter relationships predicted more positive memories of friends, supporting a compensatory model. The gender of parent also mattered, with fathers having a more influential role on affect for memories of friends.

Best friends' discussions of social dilemmas.

Science.gov (United States)

McDonald, Kristina L; Malti, Tina; Killen, Melanie; Rubin, Kenneth H

2014-02-01

Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4% female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents' social and moral development.

The main aim of this paper was to assess the in vitro response of healthy and coeliac human faecal microbiota to gluten-friendly bread (GFB). Thus, GFB and control bread (CB) were fermented with faecal microbiota in pH-controlled batch cultures. The effects on the major groups of microbiota were monitored over 48 h incubations by fluorescence in situ hybridisation. Short-chain fatty acids (SCFAs) were measured by high-performance liquid chromatography (HPLC). Furthermore, the death kinetics of Lactobacillus acidophilus, Bifidobacterium animalis subsp. lactis, Staphylococcus aureus, and Salmonella Typhimurium in a saline solution supplemented with GFB or CB were also assessed. The experiments in saline solution pinpointed that GFB prolonged the survival of L. acidophilus and exerted an antibacterial effect towards S. aureus and S. Typhimurium. Moreover, GFB modulated the intestinal microbiota in vitro, promoting changes in lactobacilli and bifidobacteria members in coeliac subjects. A final multivariate approach combining both viable counts and metabolites suggested that GFB could beneficially modulate the coeliac gut microbiome; however, human studies are needed to prove its efficacy.

Simple friend recommendation algorithms such as similarity, popularity and social aspects is the basic requirement to be explored to methodically form high-performance social friend recommendation. Suggestion of friends is followed. No tags of character were followed. In the proposed system, we use an algorithm for network correlation-based social friend recommendation (NC-based SFR).It includes user activities like where one lives and works. A new friend recommendation method, based on network correlation, by considering the effect of different social roles. To model the correlation between different networks, we develop a method that aligns these networks through important feature selection. We consider by preserving the network structure for a more better recommendations so that it significantly improves the accuracy for better friend-recommendation.

2016-01-01

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.

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.

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.

Exploring the Notion of the Family Friendly City

There is a common perception that downtown areas will never attract families and big cities are not the best place to raise children. Particularly the downtown areas of cities been depicted as the place where criminals, prostitutes, drug-sellers, and other dangerous strangers live. People with children are more likely to look for the suburbs to find bigger housing with more affordable prices, cleaner air, richer nature, a slower lifestyle, and safer environment. However, living in the modern suburb is not always easy and cheap, especially for those who need to commute to the central city. Dealing with the long commutes can be stressful and it affects the health, happiness, and well-being of family members. As the number of modern families with both parents in the workforce is rising, the demand to live closer to the workplace is getting stronger and growing. In some parts of the world, more families increasingly want to live in the cities. This trend can be seen in the United States, Japan, Korea, and Canada. Being family-friendly has become increasingly important for modern cities as more millennial generation show the tendency to raise their families in the urban area. Moreover, it is predicted that two-thirds of world’s population will live in cities by 2030. To accommodate the growing population, in particular, those with children, modern cities should be developed to suit urban families. But what criteria and qualities make one city more family-friendly than another? What would a family-friendly city look like? To date, the number studies exploring the notion of the family-friendly city has been very limited. Most studies have been focusing on the notion of family-friendly dwellings, family-friendly workplaces, or child-friendly cities. This paper brings together and examines the dominant and recurring ideas about the family-friendly city represented in the relevant literature and current urban practices. This paper also questions whether the concept of the

The social genome of friends and schoolmates in the National Longitudinal Study of Adolescent to Adult Health

Humans tend to form social relationships with others who resemble them. Whether this sorting of like with like arises from historical patterns of migration, meso-level social structures in modern society, or individual-level selection of similar peers remains unsettled. Recent research has evaluated the possibility that unobserved genotypes may play an important role in the creation of homophilous relationships. We extend this work by using data from 5,500 adolescents from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine genetic similarities among pairs of friends. Although there is some evidence that friends have correlated genotypes, both at the whole-genome level as well as at trait-associated loci (via polygenic scores), further analysis suggests that meso-level forces, such as school assignment, are a principal source of genetic similarity between friends. We also observe apparent social–genetic effects in which polygenic scores of an individual’s friends and schoolmates predict the individual’s own educational attainment. In contrast, an individual’s height is unassociated with the height genetics of peers. PMID:29317533

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 demonstration that humans can learn to modulate their own brain activity based on feedback of neurophysiological signals opened up exciting opportunities for fundamental and applied neuroscience. Although EEG-based neurofeedback has been long employed both in experimental and clinical investigation, functional MRI (fMRI)-based neurofeedback emerged as a promising method, given its superior spatial resolution and ability to gauge deep cortical and subcortical brain regions. In combination with improved computational approaches, such as pattern recognition analysis (e.g., Support Vector Machines, SVM), fMRI neurofeedback and brain decoding represent key innovations in the field of neuromodulation and functional plasticity. Expansion in this field and its applications critically depend on the existence of freely available, integrated and user-friendly tools for the neuroimaging research community. Here, we introduce FRIEND, a graphic-oriented user-friendly interface package for fMRI neurofeedback and real-time multivoxel pattern decoding. The package integrates routines for image preprocessing in real-time, ROI-based feedback (single-ROI BOLD level and functional connectivity) and brain decoding-based feedback using SVM. FRIEND delivers an intuitive graphic interface with flexible processing pipelines involving optimized procedures embedding widely validated packages, such as FSL and libSVM. In addition, a user-defined visual neurofeedback module allows users to easily design and run fMRI neurofeedback experiments using ROI-based or multivariate classification approaches. FRIEND is open-source and free for non-commercial use. Processing tutorials and extensive documentation are available.

Building Child Friendly Cities in the MENA region

Nour, Osman El Hassan M.

2013-09-01

The notion of Child Friendly Cities (CFCs) was first developed during the Second United Nations Conference on Human Settlements (HABITAT II), held in Istanbul in 1996. The concept is based on four general principles of the United Nations Convention on the rights of the child: (1) fair treatment of every child, regardless of ethnicity, gender, religion, socioeconomic background etc.; (2) top priority of the best interests of the child; (3) the child's right to a better life and development; and (4) respect of children's views. In a CFC, children are encouraged to take part in the decision making processes that affect their lives. Instead of starting yet another programme for children, the development of a CFC mobilises and connects existing agencies and actors. Giving examples of some cities in the Middle East and North Africa (MENA) region, this paper demonstrates that building CFCs has induced the development of mechanisms and structures which have enabled cities to address children's issues in a systematic manner. These mechanisms and structures include: a municipal child-friendly legal framework, local development councils and NGO networks and local municipal development offices. The author argues that in building CFCs, the role of municipal authorities is indispensable in responding to the needs of children and young people within the municipalities' mandates.

Taking a step towards greener future: A practical guideline for eco-friendly dentistry

Full Text Available Humans have had a tremendous impact on the ecology and of late have rapidly damaged its delicate balance. Dentists as protectors of oral health should not limit their responsibilities to patient treatment but also inculcate methods to protect the environment as well. Thus the concept of eco-friendly dentistry or green dentistry has been introduced. Eco-dentistry or "green dentistry" is a practice of dentistry using technologies and materials that promote and protect the planet. It is a thought process, an attitude, and a guide for making earth friendly choices in dental practice. This article intends to provide guidance to practitioners about the practical changes we can make in practice, so as to minimizing the release of potential pollutants and reduce the impact of dentistry on Earth.

[The family-friendly hospital: (how) does it work?].

Heller, A R; Heller, S C

The demographic development in Germany is heading towards a significant shortage in specialists within the next 10-15 years with an increased demand for health services at the same time. The three-stage model of family life planning (work, family phase, return) will also be gradually replaced by a model of simultaneous compatibility of family and work. This change in values, although initiated by the parents themselves, may turn out to be a crucial countermeasure in national economy against the demography-related loss of qualified personnel. For these three trends the economic need arises to minimize family-related absence of our well-trained, motivated and reliable doctors from the clinical departments through implementation of family-friendly human resources policies and supporting measures by the employers. In a representative survey 26% of respondents with children had in the past already changed their workplace to ensure a better match of work and family duties. In this regard the compatibility of family and professional responsibilities had a higher impact on the selection of the employer than a high income. Accordingly, a work-life competence oriented business plan will represent the crucial factor within the competition between universities, hospitals and professional disciplines to attract high potential bearers although a sustained change of the traditional hospital culture is mandatory. Anaesthesia-related fields of development regarding family-friendly corporate governance are working hours and organization of work, part-time jobs even for managers and fathers, and staff development. In the hospital daily routine, in particular, creative solutions meeting the local demands are deemed necessary that do not involve the use of high financial resources. Family-friendly personnel policy not only arises from altruistic enthusiasm but also pays off economically. This article discusses the necessity, opportunities and threads of family-oriented hospital

The most common friend first immunization

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)

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

Savage, Matthew W; Menegatos, Lisa; Roberto, Anthony J

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.

Eco-friendly dentistry: Need of future. An overview

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.

Influence of Friends on Children’s Physical Activity: A Review

Science.gov (United States)

Maturo, Claire C.

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

To determine changes in the breastfeeding practices of mothers after receiving counseling on Ten Steps to Successful Breastfeeding as defined by the Baby Friendly Hospital Initiative comparing baby friendly hospitals (BFHs) and non-baby-friendly hospitals in Sindh, Pakistan. Methods: The observational study was conducted from June 2007 to June 2009 in randomly selected baby-friendly and non-baby-friendly hospitals of Sindh, Pakistan. Non-probability purposive sampling was employed. The maternity staff was trained on Ten Steps to Successful Breastfeeding. The changes in breastfeeding practices were analysed by SPSS version 15. Results: A total of 236 women were included in the study. Of them, 196 (83.05%) were from baby-friendly hospitals and 40 (16.94%) from non-baby-friendly hospitals. Besides, 174 (88.7%) mothers in baby-friendly hospitals and 5 (12.5%) in non-baby-friendly hospitals during antenatal care received counseling by healthcare providers. There was an increase in breastfeeding practice up to 194 (98.97%) in the first category compared to 12 (30%) in the other category. Conclusion: Counseling under the Baby Friendly Hospital Initiative improved breastfeeding practices up to 98.97% in baby-friendly compared to non-baby-friendly hospitals. (author)

Parents and friends both matter: simultaneous and interactive influences of parents and friends on European schoolchildren's energy balance-related behaviours - the ENERGY cross-sectional study.

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 paper contributes empirical input to current reasoning about consumers' propensity to behave in an environmentally friendly way in different domains. Spe-cifically, we investigate whether environmentally friendly behaviours spread to more and more areas of the consumption pattern in a virtuous...... circle and whether it is a necessary prerequisite for a virtuous circle to emerge and to continue to work that the individual possesses certain general values or ethical norms. The data material is a three-wave panel study with a large random sample of Danish consumers. The data were analysed by means...... of structural equation modelling and other techniques. Cases of transfer of environment-friendly conduct between behavioural categories are found, but only in a few of the possible instances and only of a modest size. The panel analysis also identifies a few negative cross-lagged effects. Such effects may...

Lipedema: friend and foe.

Torre, Yanira Sanchez-De la; Wadeea, Rita; Rosas, Victoria; Herbst, Karen L

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.

Huisman, Chip

2014-05-01

Using stochastic actor-based models for longitudinal network analysis, this study examines the role of friends' smoking attitudes and behavior for Dutch adolescents' smoking behavior in four secondary schools (N = 875). The data were collected in two waves in two small suburban towns under second graders in 2008 to 2009 by means of a standardized questionnaire. Stochastic actor-based models for longitudinal network analysis can control for friendship selection while examining the effect of friends' attitudes and smoking behavior on the smoking behavior of a student. The findings suggest that friends tend to select each other on similar smoking behavior. Influence of friends' smoking behavior seems to play no role. In one school, an effect of friends' attitudes towards smoking on the smoking behavior is found. The implications for future research are to consider attitudes when examining the influence of friendship network on smoking behavior. The main limitation of this study lies in the limited sample, which makes generalizations to the general population difficult.

Global baby-friendly hospital initiative monitoring data: update and discussion.

The World Health Organization (WHO)/UNICEF Baby-Friendly Hospital Initiative (BFHI) was developed to support the implementation of the Ten Steps for Successful Breastfeeding. The purpose of this study is to assess trends in the numbers facilities ever-designated "baby-friendly," to consider uptake of the new WHO/UNICEF BFHI materials, and to consider implications for future breastfeeding support. The national contacts from the 2006-2007 UNICEF BFHI update were recontacted, as were WHO and UNICEF officers worldwide, to ascertain the number of hospitals ever-designated "baby-friendly," presence of a government breastfeeding oversight committee, use of the new BFHI materials and, if yes, use of the new maternity or human immunodeficiency virus (HIV) materials. Seventy countries reporting in 2010-2011 and the updates from an additional 61 reporting in 2006-2007 (n=131, or 66% of the 198 countries) confirm that there are at least 21,328 ever-designated facilities. This is 27.5% of maternities worldwide: 8.5% of those in industrialized countries and 31% in less developed settings. In 2010, government committees were reported by 18 countries, and 34 reported using the new BFHI materials: 14 reported using the maternity care and 11 reported using the HIV materials. Rates of increase in the number of ever-certified "baby-friendly" hospitals vary by region and show some chronological correlation with trends in breastfeeding rates. Although it is not possible to attribute this increase to the BFHI alone, there is ongoing interest in Ten Steps implementation and in BFHI. The continued growth may reflect the dedication of ministries of health and national BFHI groups, as well as increasing recognition that the Ten Steps are effective quality improvement practices that increase breastfeeding and synergize with community interventions and other program efforts. With renewed interest in maternal/neonatal health, revitalization of support for Ten Steps and their effective

Parental Strategies for Knowledge of Adolescents’ Friends: Distinct from Monitoring?

Miller, Brenda A.; Duke, Michael R.; Ames, Genevieve M.

2012-01-01

Parental monitoring is defined as a set of behaviors used to gain knowledge about an adolescent’s whereabouts, friends and associates, and activities. However, can knowledge of adolescents’ whereabouts/activities, and friends all be attained through the same strategies? Or do they require their own strategies? This study used qualitative interviews with 173 parents of older adolescents from 100 families. Emergent themes described strategies by which parents gain information about their adolescents’ friends and the substance use of those friends. The strategies included direct interaction with the friend, gaining information from the teen, using second-hand sources, and making assumptions. Some of these strategies were consistent with previous research, while others raise new questions and provide interesting new directions to pursue. Primarily, additional consideration needs to be given to assessments of parental monitoring that include strategies for gaining knowledge of adolescents’ friends and their substance use.

2016-11-01

Intimate partner violence (IPV) affects people connected to survivors as well as survivors themselves. Despite this, we do not have measures assessing IPV's impact on others. The Impact on Friends measure was developed to understand the impact of disclosure of sexual assault (SA) on friends of survivors. In the present study, the Impact on Friends measure was modified to apply to IPV and administered to two separate online samples. Exploratory factor analysis in one sample (U.S.-based participants) revealed a very similar factor structure to the original Impact on Friends measure, consisting of Emotional Distress, Validation, and Confusion. This factor solution was then applied to the next sample (mostly Indian participants), resulting in an adequate model fit. The Impact on Friends-IPV measure has adequate reliability. One of its factors, Emotional Distress, is related to increased depression and post-traumatic distress disorder symptoms of friends, but only in the U.S. These findings suggest that even though the same dimensions have been found in both a U.S. and an Indian sample, how disclosure of IPV on friends relates to psychological symptoms may differ. This study suggest that there is at least some overlap in the experiences of friends of IPV and SA survivors, but that certain dimensions of the measure may have different relationships to other phenomena in different cultures. © The Author(s) 2015.

Why acting environmentally-friendly feels good: Exploring the role of self-image

Directory of Open Access Journals (Sweden)

Leonie A Venhoeven

2016-11-01

Full Text Available Recent research suggests that engagement in environmentally-friendly behavior can feel good. Current explanations for such a link do not focus on the nature of environmentally-friendly behavior itself, but rather propose well-being is more or less a side-benefit; behaviors that benefit environmental quality (e.g. spending one’s money on people rather than products also tend to make us feel good. We propose that the moral nature of environmentally-friendly behavior itself may elicit positive emotions as well, because engaging in this behavior can signal one is an environmentally-friendly and thus a good person. Our results show that engagement in environmentally-friendly behavior can indeed affect how people see themselves: participants saw themselves as being more environmentally-friendly when they engaged in more environmentally-friendly behavior (Study 1. Furthermore, environmentally-friendly behavior resulted in a more positive self-image, more strongly when it was voluntarily engaged in, compared to when it was driven by situational constraints (Study 2. In turn, the more environmentally-friendly (Study 1 and positive (Study 2 people saw themselves, the better they felt about acting environmentally-friendly. Together, these results suggest that the specific self-signal that ensues from engaging in environmentally-friendly behavior can explain why environmentally-friendly actions may elicit a good feeling.

Network-Friendly Gossiping

Serbu, Sabina; Rivière, Étienne; Felber, Pascal

The emergence of large-scale distributed applications based on many-to-many communication models, e.g., broadcast and decentralized group communication, has an important impact on the underlying layers, notably the Internet routing infrastructure. To make an effective use of network resources, protocols should both limit the stress (amount of messages) on each infrastructure entity like routers and links, and balance as much as possible the load in the network. Most protocols use application-level metrics such as delays to improve efficiency of content dissemination or routing, but the extend to which such application-centric optimizations help reduce and balance the load imposed to the infrastructure is unclear. In this paper, we elaborate on the design of such network-friendly protocols and associated metrics. More specifically, we investigate random-based gossip dissemination. We propose and evaluate different ways of making this representative protocol network-friendly while keeping its desirable properties (robustness and low delays). Simulations of the proposed methods using synthetic and real network topologies convey and compare their abilities to reduce and balance the load while keeping good performance.

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.

Getting to Family-Friendly in Your Department

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.

Persistent application of pesticides often leads to accumulation in the environment and to the development of resistance in various organisms. These chemicals frequently degrade slowly and have the potential to bio-accumulate across the food chain and in top predators. Cancer and neuronal damage at genomic and proteomic levels have been linked to exposure to pesticides in humans. These negative effects encourage search for new sources of biopesticides that are more "environmentally-friendly" to the environment and human health. Many plant or fungal compounds have significant biological activity associated with the presence of secondary metabolites. Plant biotechnology and new molecular methods offer ways to understand regulation and to improve production of secondary metabolites of interest. Naturally occurring crop protection chemicals offer new approaches for pest management by providing new sources of biologically active natural products with biodegradability, low mammalian toxicity and environmentally-friendly qualities. Latin America is one of the world's most biodiverse regions and provide a previously unsuspected reservoir of new and potentially useful molecules. Phytochemicals from a number of families of plants and fungi from the southern Andes and from Mexico have now been evaluated. Andean basidiomycetes are also a great source of scientifically new compounds that are interesting and potentially useful. Use of biopesticides is an important component of integrated pest management (IPM) and can improve the risks and benefits of production of many crops all over the world.

What's in a Friendship? Partner Visibility Supports Cognitive Collaboration between Friends.

Science.gov (United States)

Brennan, Allison A; Enns, James T

2015-01-01

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.

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.

Daily well-being of older adults with friends and family.

Larson, R; Mannell, R; Zuzanek, J

1986-06-01

Family members are the major source of physical and emotional support for older adults, yet researchers suggest that friendships have a stronger bearing on subjective well-being. In this research we sought an explanation for this inconsistency in older adults' immediate experiences with friends. Retired adults provided self-reports on their subjective states at random moments during a typical week. Analyses of these reports confirmed the prediction that older adults have more favorable experiences with their friends than with family members. The difference is partly attributable to the greater frequency of active leisure activities with friends, but is also due to unique qualities of interactions with friends that facilitate transcendence of mundane daily realities. We propose that friends provide an immediate situation of openness, reciprocity, and positive feedback that engenders enjoyment and subjectively meaningful exchanges.

Perceptions of friendship among youth with distressed friends.

Hill, Erin N; Swenson, Lance P

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.

By changing individual food consumption patterns, it might be possible to reduce greenhouse gas emissions associated with climate change. The aim of the current study was to examine how perceptions of the moral intensity of climate change are related to climate friendly-food choices. The participants were 350 Finnish university students in the social and behavioral sciences who completed a questionnaire during class. The results indicated that moral perceptions mainly affected the moral evaluation and intentions to make climate-friendly food choices. We suggest that the results can be used to promote climate-friendly food choices, for example, by increasing the recognition of climate change as a moral imperative and by combining environmental motives with other relevant food choice motives.

Three friendly walkers

Jensen, Iwan

2017-01-01

More than 15 years ago Guttmann and Vöge (2002 J. Stat. Plan. Inference 101 107), introduced a model of friendly walkers. Since then it has remained unsolved. In this paper we provide the exact solution to a closely allied model which essentially only differs in the boundary conditions. The exact solution is expressed in terms of the reciprocal of the generating function for vicious walkers which is a D-finite function. However, ratios of D-finite functions are inherently not D-finite and in this case we prove that the friendly walkers generating function is the solution to a non-linear differential equation with polynomial coefficients, it is in other words D-algebraic. We find using numerically exact calculations a conjectured expression for the generating function of the original model as a ratio of a D-finite function and the generating function for vicious walkers. We obtain an expression for this D-finite function in terms of a {{}2}{{F}1} hypergeometric function with a rational pullback and its first and second derivatives. Dedicated to Tony Guttmann on the occasion of his 70th birthday.

Friends First? The Peer Network Origins of Adolescent Dating

Kreager, Derek A.; Molloy, Lauren E.; Moody, James; Feinberg, Mark E.

2015-01-01

The proximity of dating partners in peer friendship networks has important implications for the diffusion of health-risk behaviors and adolescent social development. We derive two competing hypotheses for the friendship-romance association. The first predicts that daters are proximally positioned in friendship networks prior to dating and that opposite-gender friends are likely to transition to dating. The second predicts that dating typically crosses group boundaries and opposite-gender friends are unlikely to later date. We test these hypotheses with longitudinal friendship data for 626 9th grade PROSPER heterosexual dating couples. Results primarily support the second hypothesis: romantic partners are unlikely to be friends in the previous year or share the same cohesive subgroup, and opposite-gender friends are unlikely to transition into dating.

NGAL is a promising novel biomarker for acute kidney injury (AKI) and chronic kidney disease (CKD). More rapid and user-friendly methods are needed for the timely monitoring of NGAL in human urine and serum. UCP technology-based lateral flow assay (UPT-LFA) was developed for rapid, user-friendly and quantitative detection of the NGAL in human serum specimens and urine specimens. Under optimal conditions, the UPT-LFA displayed a rapid response to NGAL with a LOD of 7.68ng/mL and detection range from 7.68 to 1000ng/mL. The UPT-LFA method was compared with commercial immunoturbidimetry (103 urine specimens), and by ELISA (26 serum specimens), respectively. The results demonstrated that the UPT-LFA was consistent with immunoturbidimetry assay, reporting a 97.92% of positive and 92.73% of negative coincidence rates, respectively. Meanwhile, the concordance rate between UPT-LFA and ELISA, as shown by correlative regression analysis, was also high (R 2 =0.95). The whole assay can be completed within 30min compared to 4h consuming with ELISA. The research implies that, the UPT-LFA provides a potential to be used in point of care testing (POCT) to define early acute kidney injury with advantages of user-friendly and rapid testing, promising this new assay a bright future.

Zeng, Defang; Fan, Zhao; Tian, Xu; Wang, Wenjin; Zhou, Mingchun; Li, Haochuan

2018-06-01

Traditional seed coating agents often contain toxic ingredients, which contaminate the environment and threaten human health. This paper expounds a method of preparing a novel environment-friendly seed coating agent for maize and researches its mechanism of action. The natural polysaccharide polymer, which is the main active ingredient of this environment-friendly seed coating agent, has the characteristics of innocuity and harmlessness, and it can replace the toxic ingredients used in traditional seed coating agents. This environment-friendly seed coating agent for maize was mainly made up of the natural polysaccharide polymer and other additives. The field trials results showed that the control efficacy of Helminthosporium maydis came to 93.72%, the anti-feeding rate of cutworms came to 81.29%, and the maize yield was increased by 17.75%. Besides, the LD 50 value (half the lethal dose in rats) of this seed coating agent was 10 times higher than that of the traditional seed coating agents. This seed coating agent could improve the activity of plant protective enzymes (peroxidase, catalase and superoxidase dismutase) and increase the chlorophyll content. This seed coating agent has four characteristics of disease prevention, desinsectization, increasing yield and safety. Results of mechanism analyses showed that this seed coating agent could enhance disease control effectiveness by improving plant protective enzymes activity and increase maize yield by improving chlorophyll content. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

A fast algorithm for identifying friends-of-friends halos

Science.gov (United States)

Feng, Y.; Modi, C.

2017-07-01

We describe a simple and fast algorithm for identifying friends-of-friends features and prove its correctness. The algorithm avoids unnecessary expensive neighbor queries, uses minimal memory overhead, and rejects slowdown in high over-density regions. We define our algorithm formally based on pair enumeration, a problem that has been heavily studied in fast 2-point correlation codes and our reference implementation employs a dual KD-tree correlation function code. We construct features in a hierarchical tree structure, and use a splay operation to reduce the average cost of identifying the root of a feature from O [ log L ] to O [ 1 ] (L is the size of a feature) without additional memory costs. This reduces the overall time complexity of merging trees from O [ L log L ] to O [ L ] , reducing the number of operations per splay by orders of magnitude. We next introduce a pruning operation that skips merge operations between two fully self-connected KD-tree nodes. This improves the robustness of the algorithm, reducing the number of merge operations in high density peaks from O [δ2 ] to O [ δ ] . We show that for cosmological data set the algorithm eliminates more than half of merge operations for typically used linking lengths b ∼ 0 . 2 (relative to mean separation). Furthermore, our algorithm is extremely simple and easy to implement on top of an existing pair enumeration code, reusing the optimization effort that has been invested in fast correlation function codes.

Stereotype Threat and Perceptions of Family-Friendly Policies among Female Employees.

von Hippel, Courtney; Kalokerinos, Elise K; Zacher, Hannes

2016-01-01

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.

The more friends, the less political talk? Predictors of Facebook discussions among college students.

Jang, S Mo; Lee, Hoon; Park, Yong Jin

2014-05-01

Although previous research has indicated that Facebook users, especially young adults, can cultivate their civic values by talking about public matters with their Facebook friends, little research has examined the predictors of political discussion on Facebook. Using survey data from 442 college students in the United States, this study finds that individual characteristics and network size influence college students' expressive behavior on Facebook related to two controversial topics: gay rights issues and politics. In line with previous studies about offline political discussion, the results show that conflict avoidance and ambivalence about target issues are negatively associated with Facebook discussions. Perhaps the most interesting finding is that users who have a large number of Facebook friends are less likely to talk about politics and gay rights issues on Facebook despite having access to increasing human and information resources. Theoretical implications of these findings and future directions are addressed.

To investigate the implementation of eco-friendly dental office strategies by Jordanian dentists. Self-designed questionnaires were provided to 150 dentists working in private dental practices in the city of Amman, the capital of Jordan. Dentists' names and addresses were obtained from the Jordanian Dental Association. Overall, the level of knowledge about eco-friendly dental offices strategies was high for amalgam, radiology, paper waste, infection control and energy and water conservation. In terms of implementation, the majority of Jordanian dentists apply few eco-friendly dental offices strategies. The most frequently identified barriers to implementation of eco-friendly dental offices strategies were cost and lack of incentives from the government. Most Jordanian dental practices are not eco-friendly. A continued focus on the impact of dental practices on the environment is needed through formal and continuing dental education. Results of this study can guide policy development to encourage implementation of eco-friendly strategies. © 2013 FDI World Dental Federation.

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.

Higgs friends and counterfeits at hadron colliders

International Nuclear Information System (INIS)

Fox, Patrick J.; Tucker-Smith, David; Weiner, Neal

2011-01-01

We consider the possibility of 'Higgs counterfeits' - scalars that can be produced with cross sections comparable to the SM Higgs, and which decay with identical relative observable branching ratios, but which are nonetheless not responsible for electroweak symmetry breaking. We also consider a related scenario involving 'Higgs friends,' fields similarly produced through gg fusion processes, which would be discovered through diboson channels WW,ZZ,γγ, or even γZ, potentially with larger cross sections times branching ratios than for the Higgs. The discovery of either a Higgs friend or a Higgs counterfeit, rather than directly pointing towards the origin of the weak scale, would indicate the presence of new colored fields necessary for the sizable production cross section (and possibly new colorless but electroweakly charged states as well, in the case of the diboson decays of a Higgs friend). These particles could easily be confused for an ordinary Higgs, perhaps with an additional generation to explain the different cross section, and we emphasize the importance of vector boson fusion as a channel to distinguish a Higgs counterfeit from a true Higgs. Such fields would naturally be expected in scenarios with 'effective Z's,' where heavy states charged under the SM produce effective charges for SM fields under a new gauge force. We discuss the prospects for discovery of Higgs counterfeits, Higgs friends, and associated charged fields at the LHC.

von Hippel, Courtney; Kalokerinos, Elise K.; Zacher, Hannes

2017-01-01

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. PMID:28111560

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. 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. Girls' binge eating was associated with their male friends' (odds ratio = 2.33; p = 0.03) and fathers' binge eating (odds ratio = 3.38; p = 0.02), but not with their female friends' or mothers' binge eating (p > 0.05). For boys, binge eating was not associated with parents' or friends' behavior. 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. Copyright © 2013 Wiley Periodicals, Inc.

Parents and friends both matter: simultaneous and interactive influences of parents and friends on European schoolchildren’s energy balance-related behaviours – the ENERGY cross-sectional study

Science.gov (United States)

2014-01-01

Background 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. Methods 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. Results 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

What’s in a Friendship? Partner Visibility Supports Cognitive Collaboration between Friends

Brennan, Allison A.; Enns, James T.

2015-01-01

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

Introduction of Microbial Biopolymers in Soil Treatment for Future Environmentally-Friendly and Sustainable Geotechnical Engineering

Directory of Open Access Journals (Sweden)

Ilhan Chang

2016-03-01

Full Text Available Soil treatment and improvement is commonly performed in the field of geotechnical engineering. Methods and materials to achieve this such as soil stabilization and mixing with cementitious binders have been utilized in engineered soil applications since the beginning of human civilization. Demand for environment-friendly and sustainable alternatives is currently rising. Since cement, the most commonly applied and effective soil treatment material, is responsible for heavy greenhouse gas emissions, alternatives such as geosynthetics, chemical polymers, geopolymers, microbial induction, and biopolymers are being actively studied. This study provides an overall review of the recent applications of biopolymers in geotechnical engineering. Biopolymers are microbially induced polymers that are high-tensile, innocuous, and eco-friendly. Soil–biopolymer interactions and related soil strengthening mechanisms are discussed in the context of recent experimental and microscopic studies. In addition, the economic feasibility of biopolymer implementation in the field is analyzed in comparison to ordinary cement, from environmental perspectives. Findings from this study demonstrate that biopolymers have strong potential to replace cement as a soil treatment material within the context of environment-friendly construction and development. Moreover, continuing research is suggested to ensure performance in terms of practical implementation, reliability, and durability of in situ biopolymer applications for geotechnical engineering purposes.

McAdams, Tom A; Salekin, Randall T; Marti, C Nathan; Lester, Whiney S; Barker, Edward D

2014-04-01

Delinquency and substance use (SU) are commonly comorbid during adolescence. In the present study we investigate this co-morbidity with 3 main objectives: 1. Evaluate reciprocal relationships between delinquency/SU across early adolescence. 2. Assess the impact of older male friends, low parental knowledge and friends' delinquency on subsequent development and inter-relationships of delinquency and SU. 3. Evaluate sex differences in these relationships. We applied cross-lagged structural equation models to the analysis of a longitudinal sample (n=3699). Findings demonstrated: (1) At ages 13-14 delinquency predicted SU more so than vice versa but effects became equal between ages 14 and 15. (2) Low parental knowledge and friends' delinquency predicted delinquency and SU. Older male friends predicted ASB. (3) Sex differences were present. For example, in the absence of antisocial friends low parent knowledge at age 12 indirectly predicted increased age 15 SU for girls more than boys.

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.

Loureiro-Vieira, Sara; Costa, Vera Marisa; de Lourdes Bastos, Maria; Carvalho, Félix; Capela, João Paulo

2017-08-01

Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent neuropsychiatry disorders in children and adolescents, and methylphenidate (MPH) is a first-line stimulant drug available worldwide for its treatment. Despite the proven therapeutic efficacy, concerns have been raised regarding the possible consequences of chronic MPH exposure during childhood and adolescence. Disturbances in the neurodevelopment at these crucial stages are major concerns given the unknown future life consequences. This review is focused on the long-term adverse effects of MPH to the brain biochemistry. Reports conducted with young and/or adolescent animals and studies with humans are reviewed in the context of long-term consequences after early life-exposure. MPH pharmacokinetics is also reviewed as there are differences among laboratory animals and humans that may be relevant to extrapolate the findings. Studies reveal that exposure to MPH in laboratory animals during young and/or adolescent ages can impact the brain, but the outcomes are dependent on MPH dose, treatment period, and animal's age. Importantly, the female sex is largely overlooked in both animal and human studies. Unfortunately, human reports that evaluate adults following adolescent or child exposure to MPH are very scarce. In general, human data indicates that MPH is generally safe, although it can promote several brain changes in early ages. Even so, there is a lack of long course patient evaluation to clearly establish whether MPH-induced changes are friendly or foe to the brain and more human studies are needed to assess the adult brain changes that arise from early MPH treatment.

Ayotte, Brian; Mehta, Clare; Alfonso, Jacqueline

2017-09-01

Objective We examined health-related communication between same-sex and other-sex friends and how communication was related to health-related behavior. Participants Data from 243 emerging adults attending college ( Mage = 18.96, SD = 1.43; 55.6% male) were analyzed. Methods Participants completed measures assessing the frequency in which they talked about and made plans to engage in exercise and nutrition-related behaviors with friends, as well as how often they engaged in exercise and nutrition-related behaviors. Results In general, participants reported more health-related communication with same-sex friends. Health-related communication with same-sex friends was positively related to health behaviors for men and women. However, the pattern of results differed for men and women depending on the topic of communication and the behavior being examined. Conclusion Our study extends the literature by examining the role of sex of friends in health communication and planning and how interactions with friends relate to health-promoting behavior.

Can friends protect genetically vulnerable children from depression?

Brendgen, Mara; Vitaro, Frank; Bukowski, William M; Dionne, Ginette; Tremblay, Richard E; Boivin, Michel

2013-05-01

The study examined whether reciprocal friendship quantity or quality can mitigate genetic vulnerability for depression symptoms in children. The sample comprised 168 monozygotic twin pairs and 126 same-sex dizygotic twin pairs assessed in Grade 4 (mean age = 10.04 years). Friendship participation was measured via reciprocal nominations of close friendships within the classroom. Friendship quality was measured through self-reports. Depression symptoms were measured through teacher and peer reports. Genetic vulnerability for depression symptoms was unrelated to friendship participation or the number of reciprocal friends, but it was negatively related to positive friendship quality. In line with gene-environment interaction, genetic risk effects on depression symptoms were mitigated in girls who had at least one close reciprocal friend. In boys, only moderate main effects of genetic vulnerability and friendship participation were found but no interaction between them. However, among boys with at least one reciprocal friend, a greater number of friends was related to fewer depression symptoms whereas no cumulative effect of friendship was found for girls. Finally, positive friendship quality was related to fewer depression symptoms in girls and boys even when controlling for genetic risk. The findings emphasize the importance of teaching social interactional skills that promote high-quality friendship relations to help prevent the development of depression symptoms in children.

2011-01-01

Objective: This study employed a prospective design to examine the role of friend and partner relationship quality 1 year following substance use disorder treatment in the association between depressive symptoms at discharge from treatment and abstinence from substance use 2 years after treatment. Method: The sample consisted of 1,453 male veterans who used alcohol and at least one other substance in the 3 months before treatment admission, who completed treatment, and who were abstinent from substances during the 2 weeks before discharge. Results: Fewer depressive symptoms at treatment discharge predicted better relationship quality with friends and a partner at 1 -year follow-up, as well as abstinence from substance use at 2-year follow-up. Furthermore, friend and partner relationship quality at 1 year predicted abstinence from substance use at 2 years. Friend relationship quality at 1 year mediated part of the association between fewer depressive symptoms at treatment discharge and abstinence at 2-year follow-up. Conclusions: A stronger focus in treatment on reducing depressive symptoms and enhancing the quality of patients' relationships with their friends and partner may increase the likelihood of long-term abstinence.

Raudsepp, Lennart; Riso, Eva-Maria

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.

In this study, a new eco-friendly approach for green synthesis of silver nanoparticles (AgNPs) by using the fruits of Cornus officinalis aqueous extract as a reducing and stabilizing agent. The so-synthesized AgNPs showed quasi-spherical in shape with uniform dispersal and an average mean size of 11.7nm. Water soluble biomolecules such as flavonoids and/or anthocyanins from the extract played important roles in the nanoparticles formation. The AgNPs displayed distinctive cytotoxicity activities against human prostate cancer (PC-3) and human liver cancer (HepG2) cell lines. The results provided a low cost, nontoxic and eco-friendly approach for synthesizing metal nanoparticles to explore alternative anticancer agents on the way fighting against cancer in future.

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.

A Summary of Environmentally Friendly Turbine Design Concepts

Energy Technology Data Exchange (ETDEWEB)

Odeh, Mufeed [United States Geological Survey - BRD, Turners Falls, MA (United States)

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.

Establishing an environmental friendly taxation system, designing to have a sustainable development and environmental conservation simultaneously, is an important problem to be solved. Following the study on calculation of water and energy subsidy in previous year, the amount of environmental unfriendly subsidy in transportation and agriculture was calculated. Based on the introduction plan of new environmental tax, such as carbon tax and product share, a scheme of environmental friendly taxation reform was proposed. 48 refs., 5 figs., 88 tabs.

The effect of friend selection on social influences in obesity.

Science.gov (United States)

Trogdon, Justin G; Allaire, Benjamin T

2014-12-01

We present an agent-based model of weight choice and peer selection that simulates the effect of peer selection on social multipliers for weight loss interventions. The model generates social clustering around weight through two mechanisms: a causal link from others' weight to an individual's weight and the propensity to select peers based on weight. We simulated weight loss interventions and tried to identify intervention targets that maximized the spillover of weight loss from intervention participants to nonparticipants. Social multipliers increase with the number of intervention participants' friends. For example, when friend selection was based on a variable exogenous to weight, the weight lost among non-participants increased by 23% (14.3lb vs. 11.6lb) when targeting the most popular obese. Holding constant the number of participants' friends, multipliers increase with increased weight clustering due to selection, up to a point. For example, among the most popular obese, social multipliers when matching on a characteristic correlated with weight (1.189) were higher than when matching on the exogenous characteristic (1.168) and when matching on weight (1.180). Increased weight clustering also implies more obese "friends of friends" of participants, who reduce social multipliers. Copyright © 2014 Elsevier B.V. All rights reserved.

Full Text Available Abstract Friends and colleagues remember John N. Brady, Ph.D., Chief of the Virus Tumor Biology Section of the Laboratory of Cellular Oncology, who died much too young at the age of 57 on April 27, 2009 of colon cancer. John grew up in Illinois and received his Ph.D. with Dr. Richard Consigli at Kansas State University studying the molecular structure of polyomavirus. In 1984 John came to the National Institutes of Health as a Staff Fellow in the laboratory of Dr. Norman Salzman, Laboratory of Biology of Viruses NIAID, where he was among the first to analyze SV40 transcription using in vitro transcription systems and to analyze regulatory sequences for SV40 late transcription. He then trained with Dr. George Khoury in the Laboratory of Molecular Virology NCI, where he identified SV40 T-antigen as a transcriptional activator protein. His research interests grew to focus on the human retroviruses: human T-cell lymphotropic virus type I (HTLV-I and human immunodeficiency virus (HIV, analyzing how interactions between these viruses and the host cell influence viral gene regulation, viral pathogenesis and viral transformation. His research also impacted the fields of eukaryotic gene regulation and tumor suppressor proteins. John is survived by his wife, Laraine, and two sons, Matt and Kevin.

Human friendly man-machine system with advanced media technology

International Nuclear Information System (INIS)

1993-01-01

This paper deals with the methodology to implement the man-machine system (MMS) with enhanced human friendliness for nuclear power plants. The relevant technologies are investigated from the two view points: One is integrated multi-media usage for user-computer interface and the other cognitive engineering for user-task interaction. Promising MMS design methodologies, concepts, and their limitations are discussed. To overcome uncertain factors found in human behaviors or individual differences in performance and preference of operators, a design appproach to natural and flexible man-computer interactive environment is proposed by intergrated use of not only cognitive and psychological knowledge but also advanced media technology. Multi-media operator support system under development is shown as an example to evaluate the effectiveness of the new approach and future advancement is prospected. (orig.)

2017-10-20

A majority of urban residents in sub-Saharan Africa (SSA) and other developing regions live in informal settlements, or slums. Much of the discourse on slum health centres on younger generations, while an intensifying agenda on healthy ageing as yet lacks a systematic focus on slums. Similarly, the global age-friendly cities (AFC) movement does not, thus far, extend to slums. This paper examines the particular challenges that a slum-focused age-friendly initiative in SSA may need to address, and the relevance of present AFC indicators and domains for initiatives to advance the health and well-being of older slum dwellers. The analysis builds on the case of two slum communities in Nairobi, Kenya. It analyzes two bodies of relevant evidence from these settlements, namely on the health and social circumstances of older residents, and on the local application and measurement of AFC indicators. The findings point to a set of unsurprising, but also less obvious, core health and social adversities that an age-friendly initiative in such settlements would need to consider. The findings show, further, that the current AFC domains and indicators framework only partly capture these adversities, but that there is potential for adapting the framework to be meaningful for slum settings. The paper concludes by underscoring the need for, and opportunities inherent in, the pursuit of an "age-friendly slums" initiative going forward.

2010-01-01

The aim of this study was to examine the importance of family-friendly features in residency program selection, benefits offered to and used by residents, and importance of benefits in future job selection. A survey of a random, national sample of 1000 graduating pediatric residents in 2008 was mailed and e-mailed. Survey response rate for graduating resident respondents was 59%. Among the respondents, 76% were women. Thirty-seven percent of men and 32% of women were parents. Residents with children were more likely than residents without children to rate family-friendly characteristics as very important in their residency selection (P maternity leave (88%), paternity leave (59%), individual flexibility with schedule (63%), and lactation rooms (55%), but fewer reported on-site child care (24%), care for ill children (19%), and part-time residency positions (12%). Among residents reporting availability, 77% of women with children used maternity leave and lactation rooms. Few held part-time residency positions (2%), but many expressed interest (23% of women with children). The majority of residents with and without children reported that flexibility with schedule was important in their future job selection. Most women with children (71%) and many women without children (52%) considered part-time work to be very important in their job selection. Family-friendly benefits are important to residents, particularly those with children. The data provides a benchmark for the availability and use of family-friendly features at pediatric training programs. The data also shows that many residents are unaware if benefits are offered, which suggests a need to make available benefits more transparent to residents.

Critical friends: A way to develop preceptor competence?

Science.gov (United States)

Carlson, Elisabeth

2015-11-01

Preceptorship entails for nurses to create a supportive learning and working climate where students or newcomers are given opportunities to develop professional competence. However, being a skilled and experienced nurse does not automatically turn the professional into a skilled educator as teaching of a subject is a whole different story. Preceptors need to continuously and critically reflect on their practices in order to facilitate the development of professional pedagogical competence. Critical friends are colleagues with comparable educational background evaluating the work of each other. The relationship should rely on friendship and mutual trust, adding new dimensions to the reflective process. Being engaged in a critical friendship allows the "friends" to become aware of their own shortcomings which can then be reflected on in relation to clinical as well as pedagogical practices. Being and having a critical friend might be one promising way forward for preceptors to develop pedagogical and professional competence. Copyright © 2014 Elsevier Ltd. All rights reserved.

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.

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 "Digital Friend": A knowledge-based decision support system for space crews

Science.gov (United States)

Hoermann, Hans-Juergen; Johannes, Bernd; Petrovich Salnitski, Vyacheslav

Space travel of far distances presents exceptional strain on the medical and psychological well-being of the astronauts who undertake such missions. An intelligent knowledge management system has been developed, to assist space crews on long-duration missions as an autonomous decision support system, called the "Digital Friend". This system will become available upon request for the purpose of coaching group processes and individual performance levels as well as aiding in tactical decision processes by taking crew condition parameters into account. In its initial stage, the "Digital Friend" utilizes interconnected layers of knowledge, which encompass relevant models of operational, situational, individual psycho-physiological as well as group processes. An example is the human life science model that contains historic, diagnostic, and prognostic knowledge about the habitual, actual, and anticipated patterns of physiological, cognitive, and group psychology parameters of the crew members. Depending on the available data derived from pre-mission screening, regular check-ups, or non-intrusive onboard monitoring, the "Digital Friend" can generate a situational analysis and diagnose potential problems. When coping with the effects of foreseeable and unforeseen stressors encountered during the mission, the system can provide feedback and support the crew with a recommended course of actions. The first prototype of the "Digital Friend" employs the Neurolab/Healthlab platform developed in a cooperation of DLR and IBMP. The prototype contains psycho-physiological sensors with multiple Heally Satellites that relay data to the intelligent Heally Masters and a telemetric Host station. The analysis of data from a long-term simulation study illustrates how the system can be used to estimate the operators' current level of skill reliability based on Salnitski's model [V.

What's in a Name? Sound Symbolism and Gender in First Names.

Directory of Open Access Journals (Sweden)

David M Sidhu

Full Text Available Although the arbitrariness of language has been considered one of its defining features, studies have demonstrated that certain phonemes tend to be associated with certain kinds of meaning. A well-known example is the Bouba/Kiki effect, in which nonwords like bouba are associated with round shapes while nonwords like kiki are associated with sharp shapes. These sound symbolic associations have thus far been limited to nonwords. Here we tested whether or not the Bouba/Kiki effect extends to existing lexical stimuli; in particular, real first names. We found that the roundness/sharpness of the phonemes in first names impacted whether the names were associated with round or sharp shapes in the form of character silhouettes (Experiments 1a and 1b. We also observed an association between femaleness and round shapes, and maleness and sharp shapes. We next investigated whether this association would extend to the features of language and found the proportion of round-sounding phonemes was related to name gender (Analysis of Category Norms. Finally, we investigated whether sound symbolic associations for first names would be observed for other abstract properties; in particular, personality traits (Experiment 2. We found that adjectives previously judged to be either descriptive of a figuratively 'round' or a 'sharp' personality were associated with names containing either round- or sharp-sounding phonemes, respectively. These results demonstrate that sound symbolic associations extend to existing lexical stimuli, providing a new example of non-arbitrary mappings between form and meaning.

Full Text Available 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 towards 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 towards 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.

2015-12-01

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.

Stanton, Cassandra A; Papandonatos, George; Lloyd-Richardson, Elizabeth E; Kazura, Alessandra; Shiu, Shang-Ying; Niaura, Raymond

2009-01-01

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.

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

How Adolescents with Diabetes Experience Social Support from Friends: Two Qualitative Studies

Directory of Open Access Journals (Sweden)

Louk W. H. Peters

2014-01-01

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.

2016-04-01

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.

Compare the effect of parental and best friend smoking across the stages of adolescent smoking, from being a never smoker susceptible to smoking, to being a daily smoker National cross-sectional annual survey (2002-2006 combined) of 157,637 Year 10 students aged 14 and 15 years who answered an anonymous self-administered questionnaire. The effects of smoking by parents and best friend varied with stage of adolescent tobacco smoking. Attributable risk calculations showed that parental and best friend smoking explained only 6.3% of susceptibility to smoking among never smokers, and 21.7% of non-smoking students who had ever experimented with cigarettes. The attributable risk for parental and best friend smoking progressively increased with smoking frequency, up to 78.7% for daily smoking. The effect of best friend smoking was stronger than parental smoking, although there was a synergistic effect of both variables on the risk of daily smoking. Smoking by best friend and parents are strongly associated with current smoking by adolescents, but unrelated to susceptibility to smoke among those who are non-smokers.

An algorithm for identifying the best current friend in a social network

Directory of Open Access Journals (Sweden)

Francisco Javier Moreno

2015-05-01

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.

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

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.

Great names in science represent an inexhaustible source and richness of inspiration, satisfaction and consolation, a moving and victorious force. Throughout her exemplifying life, Maria Sklodowska remained modest but with a keen sense of humor, of an outstanding style, a mine of knowledge and experience, of innovative ideas and a rich inner life. Full of love, of passion to give and to share, of natural optimism, mixed with a light melancholy, so typical for sages. She vehemently defended the love of scientific research, of the spirit of adventure and entrepreneurship and fought for international culture, for the protection of personality and talent. Maria Sklodowska left her passion to science, her dedication to work including education and training of young people, her passionate adherence to her family, her belief in her friends, her pure and profound humanity and warmth! The paper should be a homage to her, an appreciation of her work over the years, but not less a correspondence, a conversation with her! On the other hand, the present solemn occasion resuscitates the personalities of Maria and Pierre Curie and their work, in particular of Maria Sklodowska in her own native land! In this manner, it truly contributes to her immortality!

Employers' readiness for the mother-friendly workplace: an elicitation study.

Science.gov (United States)

Bai, Yeon K; Wunderlich, Shahla M; Weinstock, Marni

2012-10-01

Currently over half of mothers of infants under 1-year-old are in the workforce in the United States. These women face challenges to continue breastfeeding when they return to work 3 to 6 months post-partum. This study explored the perspectives of employers on mother-friendly environments to assess their readiness to provide breastfeeding accommodation using the elicitation under the theory of planned behaviour. Researchers conducted phone/in-person interviews with a convenient sample of 20 human resource managers from companies that had 500 or more employees in the New York metropolitan area in 2009. Content analyses identified the common concepts that represent underlying beliefs of the constructs of the theory. The demography of the participants is 40% male and 80% White, with mean ages of 34.3±8.5 years. 'Happy employees' and 'high retention rate and improved loyalty' were the most frequently mentioned (95%) benefits to the company (behavioural beliefs). Supporters of a mother-friendly environment (normative beliefs) in the workplace included 'mothers and expectant mothers (70%)', and 'managers supervising women and new mothers (55%)'. Most frequently mentioned company drawbacks (control beliefs) were 'not cost effective (65%)' and 'time consuming (65%)', followed by 'perception of special favours for some (50%)'. Workplace breastfeeding promotion efforts can be successful by reinforcing positive beliefs and addressing the challenges associated with implementation of breastfeeding accommodation through education and other incentives such as recognition of model companies and tax breaks. The identified beliefs provide a basis for the development of a quantitative instrument to study workplace breastfeeding support further. © 2011 Blackwell Publishing Ltd.

Children's perceptions of relationships with siblings, friends, and mothers: compensatory processes and links with adjustment.

Stocker, C M

1994-11-01

Links between children's psychological adjustment and individual differences in their perceptions of relationships with siblings, mothers, and friends were studied in a sample of 85 second-graders. Results indicated that characteristics of these relationships were significantly correlated with children's loneliness, depressive mood, self-esteem, and behavioral conduct. There were some links among children's perceptions of their relationships with siblings, friends, and mothers. A compensatory model of associations among adjustment and warmth in children's relationships with friends and mothers was supported. Children who reported that their relationships with either mothers, friends, or mothers and friends were characterized by high levels of warmth had significantly better adjustment outcomes than children who reported low levels of warmth in relationships with both friends and mothers. The importance of the network of children's relationships for their mental health is discussed.

A number of longitudinal studies have explored the role of friends', parents', and older siblings' smoking in children's smoking acquisition. A reasonable implication of this previous research is that intervention efforts could be beneficially directed toward countering the potential influence of friends' and possibly older siblings' smoking but not parents' smoking. However, methodological limitations of this previous research motivated our reevaluation of the role of friends', parents', and older siblings' smoking in children's smoking. Close friends' smoking status was assessed when children were in 5th grade, whereas parents' and older siblings' smoking status was assessed when children were in 3rd grade. The outcome, children's daily smoking status, was assessed in 12th grade. The setting was 40 Washington state school districts that participated in the long-term Hutchinson Smoking Prevention Project. Participants were the 4,576 families for whom close friends', parents', and older siblings' smoking status as well as children's smoking status were available. The probability that each close friend's smoking influenced the child to smoke daily was 9% (95% CI = 6%-12%), the probability that each parent's smoking influenced the child to smoke daily was 11% (95% CI = 9%-14%), and the probability that each older sibling's smoking influenced the child to smoke daily was 7% (95% CI = 1%-13%). These results suggest that close friends', parents', and siblings' smoking were similarly important influences on children's smoking. Family-focused interventions could be a valuable future direction of prevention research.

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.

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

Van Zalk, Nejra; Van Zalk, Maarten

2015-06-01

Nonclinical social anxiety in adolescence can be highly problematic, as it likely affects current and especially new social interactions. Relationships with significant others, such as close friends, mothers, and fathers, could aid socially anxious adolescents' participation in social situations, thereby helping reduce feelings of social anxiety. We examined whether making friends as well as high friendship quality help reduce social anxiety over time, and whether friends', mothers', and fathers' care interact in reducing social anxiety. Using longitudinal data from 2,194 participants in a social network (48% girls; Mage  = 13.58) followed for 3 years, we estimated friendship selection and influence processes via a continuous time-modeling approach using SIENA. We controlled for the effects of depressive symptoms, self-esteem, gender, age, and family structure. Our findings suggest that perceived care by friends mediated the effect of making friends on social anxiety. Perceptions of mother and father, as well as friend care and connectedness, respectively, did not interact in decreasing social anxiety. Nonetheless, care and connectedness with mothers, fathers, and friends jointly predicted decreases in social anxiety. Caring relationships with friends and parents each play a role in mutually protecting early adolescents against increasing in social anxiety over time. © 2014 Wiley Periodicals, Inc.

Gut Protozoa: Friends or Foes of the Human Gut Microbiota?

Science.gov (United States)

Chabé, Magali; Lokmer, Ana; Ségurel, Laure

2017-12-01

The importance of the gut microbiota for human health has sparked a strong interest in the study of the factors that shape its composition and diversity. Despite the growing evidence suggesting that helminths and protozoa significantly interact with gut bacteria, gut microbiome studies remain mostly focused on prokaryotes and on populations living in industrialized countries that typically have a low parasite burden. We argue that protozoa, like helminths, represent an important factor to take into account when studying the gut microbiome, and that their presence - especially considering their long coevolutionary history with humans - may be beneficial. From this perspective, we examine the relationship between the protozoa and their hosts, as well as their relevance for public health. Copyright © 2017 Elsevier Ltd. All rights reserved.

Widman, Laura; Choukas-Bradley, Sophia; Helms, Sarah W.; Golin, Carol E.; Prinstein, Mitchell J.

2014-01-01

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 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.

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.

The transmission of attitudes towards food: twofold specificity of similarities with parents and friends.

Science.gov (United States)

Guidetti, Margherita; Conner, Mark; Prestwich, Andrew; Cavazza, Nicoletta

2012-05-01

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.

Comparing sexual-minority and heterosexual young women's friends and parents as sources of support for sexual issues.

Science.gov (United States)

Friedman, Carly K; Morgan, Elizabeth M

2009-08-01

The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women's experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends' responses as helpful, though sexual-minority participants perceived both parents and friends' responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women's experiences seeking support for sexual issues from parents and friends.

The increased use of the Internet as a new tool in communication has changed the way people interact. This fact is even more evident in the recent development and use of friend-networking sites. However, no research has evaluated these sites and their impact on college students. Therefore, the present study was conducted to evaluate: (a) why people use these friend-networking sites, (b) what the characteristics are of the typical college user, and (c) what uses and gratifications are met by using these sites. Results indicated that the vast majority of college students are using these friend-networking sites for a significant portion of their day for reasons such as making new friends and locating old friends. Additionally, both men and women of traditional college age are equally engaging in this form of online communication with this result holding true for nearly all ethnic groups. Finally, results showed that many uses and gratifications are met by users (e.g., "keeping in touch with friends"). Results are discussed in light of the impact that friend-networking sites have on communication and social needs of college students.

The purpose of this study was to examine the structural validity of a parent and a child questionnaire that assessed parental and friends' influences on children's physical activity and investigate the associations between the derived factors, physical activity, and time spent outside. Children ( N = 154, mean age = 11.7) and 144 of their parents completed questionnaires assessing parental and friends' influences on children's physical activity. Children wore a pedometer for six days. Exploratory factor analyses revealed four factors for the parental and five for the child's questionnaire that explained 66.71% and 63.85% of the variance, respectively. Five factors were significantly associated with physical activity and five significantly associated with time spent outside. Higher correlations were revealed between "general friend support," "friends' activity norms," and physical activity ( r = 0.343 and 0.333 resp., p friend support" and time spent outside ( r = 0.460, p parental and friends' influences on physical activity from both parents and children may provide a more complete picture of influences. Parents and friends seem to influence children's physical activity behavior and time spent outside, but friends' influences may have a stronger impact on children's behaviors.

Academic Achievement and Its Impact on Friend Dynamics.

Science.gov (United States)

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.

An environmentally friendly and highly efficient gas pressure-assisted sample introduction system (GPASIS) was developed for inductively-coupled plasma mass spectrometry. A GPASIS consisting of a gas-pressure control device, a customized nebulizer, and a custom-made spray chamber was fabricated. The advantages of this GPASIS derive from its high nebulization efficiencies, small sample volume requirements, low memory effects, good precision, and zero waste emission. A GPASIS can continuously, and stably, nebulize 10% NaCl solution for more than an hour without clogging. Sensitivity, detection limits, precision, long-term stability, double charge and oxide ion levels, nebulization efficiencies, and matrix effects of the sample introduction system were evaluated. Experimental results indicated that the performance of this GPASIS, was equivalent to, or better than, those obtained by conventional sample introduction systems. This GPASIS was successfully used to determine Cd and Pb by ICP-MS in human plasma. Copyright © 2017 Elsevier B.V. All rights reserved.

Friend affiliations and school adjustment among Mexican-American adolescents: the moderating role of peer and parent support.

Espinoza, Guadalupe; Gillen-O'Neel, Cari; Gonzales, Nancy A; Fuligni, Andrew J

2014-12-01

Studies examining friendships among Mexican-American adolescents have largely focused on their potentially negative influence. The current study examined the extent to which deviant and achievement-oriented friend affiliations are associated with Mexican-American adolescents' school adjustment and also tested whether support from friends and parents moderates these associations. High school students (N = 412; 49 % male) completed questionnaires and daily diaries; primary caregivers also completed a questionnaire. Although results revealed few direct associations between friend affiliations and school adjustment, several moderations emerged. In general, the influence of friends' affiliation was strongest when support from friends was high and parental support was low. The findings suggest that only examining links between friend affiliations and school outcomes does not fully capture how friends promote or hinder school adjustment.

Full Text Available The market for environmentally friendly products in Turkey is growing, and marketing experts are trying to understand the behavior of the consumers in this market with the help of variables such as demographic factors, information, attitudes, values and life styles. This study analyzes the effects of environmental activism, environmental knowledge and the perceived seriousness of environmental problems on green buying behavior. The study involved 516 Turkish consumers, over eighteen years of age. The results show that environmental activism, environmental knowledge and the perceived seriousness of environmental problems are all meaningful factors in environmentally friendly buying behavior. It was found that the most explanatory variables are environmental activism for proactive environmentally friendly buying behavior and the perceived seriousness of environmental problems for optional environmentally friendly buying behavior. The study is significant since it will offer insights for green marketing experts who especially target specific segments as activists, voluntary simplifiers or green consumers in Turkey.

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.

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

DEMOGRAPHIC-ANAMNESTIC PARAMETERS WHICH AFFECT IMPLEMENTATION OF BABY FRIENDLY PROGRAM

Directory of Open Access Journals (Sweden)

Bozidar Jovanovic

2005-12-01

Full Text Available Various studies and extensive researches, particularly during recent years, on the advantages of breastfeeding and the use of breast milk in infant`s nourishment, have stressed its immeasurable benefit to mothers, infants, family and society. The objective of the research was to ascertain demographic and anamnestic factors affecting the implementation of the baby friendly program. The study was undertaken at OGC CC Kragujevac and based on data from 432 women. The mean age of the examinees was 25,9 years and they were 6 months younger than the corresponding examinees from similar world researches. In most cases, the examinees were from urban areas and lived in bigger families, which did not affect the implementation of the program. With equal probability, it was the first or second pregnancy and in most cases, there were no hospitalizations during the pregnancy in both tested groups. Medications are more often used during the implementation of the baby friendly program. The reason for positive influence of the use of medications during the pregnancy on implementation of the baby friendly program probably lies in better supervision of the pregnancy. The gestation age did not influence the selection into the program. By means of higher level of supervision and by the use of medications during pregnancy, we can positively influence mother`s and infant`s starting with the baby friendly programme implementation.

Barriers to climate-friendly food choices among young adults in Finland.

Mäkiniemi, Jaana-Piia; Vainio, Annukka

2014-03-01

The aim of the study was to examine how young adults in Finland perceive barriers to climate-friendly food choices and how these barriers are associated with their choices. The participants were 350 university students of the social and behavioral sciences who completed a questionnaire during class. The study found that the barriers the participants perceived as being the most relevant were different from those that were associated with the omission of climate-friendly food choices. High prices were perceived as the most relevant barrier, but were only weakly associated with the participants' food choices. Instead, habit and disbelief in the effects of food consumption on the climate were found to be the barriers that had the greatest association with climate-friendly choices. Moreover, women considered high prices and poor supply more important compared to men, whereas men considered disbelief and habit more important. In addition, vegetarians perceived fewer barriers than those who followed other diets. The findings increase our understanding of young adults' perceptions of barriers to climate-friendly food choices, as well as their effects. Copyright © 2013 Elsevier Ltd. All rights reserved.

NEPAL and China are good neighbors. In the 1980s many Chinese technicians went to Nepal to help build roads and other projects. As an interpreter with a Chinese construction cooperative, I worked there from 1993 to 1994. During my stay in Nepal, I met many different Nepalese women who impressed me deeply. My landlady Sumiyala, was the first Nepalese woman to come into my life. She was over 40 years old, a healthy and good-humored housewife. Whenever Ⅰ had time, I liked to chat with her and gradually we became friends. I remember my landlady was busy in and out of her house all day long— cleaning, cooking and taking care of her grandchildren and her parents-in-laws.

A comparison of the impact of 'seagrass-friendly' boat mooring systems on Posidonia australis.

Science.gov (United States)

Demers, Marie-Claire A; Davis, Andrew R; Knott, Nathan A

2013-02-01

Permanent boat moorings have contributed to the decline of seagrasses worldwide, prompting the development of 'seagrass-friendly' moorings. We contrasted seagrass cover and density (predominantly Posidonia australis) in the vicinity of three mooring types and nearby reference areas lacking moorings in Jervis Bay, Australia. We examined two types of 'seagrass-friendly' mooring and a conventional 'swing' mooring. 'Swing' moorings produced significant seagrass scour, denuding patches of ~9 m radius. Seagrass-friendly 'cyclone' moorings produced extensive denuded patches (average radius of ~18 m). Seagrass-friendly 'screw' moorings, conversely, had similar seagrass cover to nearby reference areas. Our findings reinforce previous work highlighting the negative effects of 'swing' and 'cyclone' moorings. In contrast, the previously unstudied 'screw' moorings were highly effective. We conclude that regular maintenance of moorings and the monitoring of surrounding seagrass are required to ensure that 'seagrass-friendly' moorings are operating effectively. This is important, as following damage Posidonia will take many decades to recover. Copyright © 2012 Elsevier Ltd. All rights reserved.

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

Alharbi, Basma Mohammed; Zhang, Xiangliang

2017-01-01

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.

Kiselica, Mark S

2003-11-01

The purpose of this article is to describe a "male-friendly" therapeutic process with troubled adolescent boys. A male-friendly process is one in which the therapist employs a wide variety of strategies and activities that are likely to appeal to male youth and that facilitate the establishment and maintenance of rapport. The nuances of practicing a male-friendly approach are highlighted and then applied in a case study of psychotherapy with a depressed adolescent boy. The implications of this approach for redefining professional conceptions about boundaries in the client-therapist relationship and reexamining inaccurate stereotypes about the emotional lives of boys are discussed.

1974-01-01

The in vitro antivirion activities of five different streptovaricin complex lots against the polycythemic strain of the Friend virus were evaluated. The assay system was based on the inhibition of the Friend virus-induced spleen foci. The virus inactivation process was shown to be susceptible to variation in temperature, pH, and time. The antivirion activity and the acute toxicity for mice, as well as the optical properties of these streptovaricin complexes, do not co-vary; this suggests that their biological activities are not associated with a single molecular structure. In addition, the antivirion activity of the five preparations of streptovaricin complex differs about 30-fold, indicating that this activity does not reside in a major component of the complex.

Koch, Anna R; Binnewies, Carmen

2015-01-01

This multisource, multilevel study examined the importance of supervisors as work-life-friendly role models for employees' boundary management. Particularly, we tested whether supervisors' work-home segmentation behavior represents work-life-friendly role modeling for their employees. Furthermore, we tested whether work-life-friendly role modeling is positively related to employees' work-home segmentation behavior. Also, we examined whether work-life-friendly role modeling is positively related to employees' well-being in terms of feeling less exhausted and disengaged. In total, 237 employees and their 75 supervisors participated in our study. Results from hierarchical linear models revealed that supervisors who showed more segmentation behavior to separate work and home were more likely perceived as work-life-friendly role models. Employees with work-life-friendly role models were more likely to segment between work and home, and they felt less exhausted and disengaged. One may conclude that supervisors as work-life-friendly role models are highly important for employees' work-home segmentation behavior and gatekeepers to implement a work-life-friendly organizational culture.

To compare and contrast military hospital and civilian hospital experiences of achieving Baby-Friendly designation, and to examine administration and staff responses as well as institutional and patient postimplementation outcomes. Staff, administration, and chairs of Baby-Friendly committees at both hospitals were interviewed. Motivating factors and perceived administrative support were similar at both institutions. Both sites saw an increase in exclusive breastfeeding rates upon discharge to a rate of 80-90%, and both noted an overall increase in delivery rates, which may also be attributed to achieving Baby-Friendly designation. Significant differences included the amount of time it took to achieve Baby-Friendly status, the number of specialties represented on the Baby-friendly committee, the percentage of employees who received training, pediatrics involvement and support, and funding sources for staff training.

To assess how euthanasia in terminally ill cancer patients affects the grief response of bereaved family and friends. Cross sectional study. Tertiary referral centre for oncology patients in Utrecht, the Netherlands. 189 bereaved family members and close friends of terminally ill cancer patients who died by euthanasia and 316 bereaved family members and close friends of comparable cancer patients who died a natural death between 1992 and 1999. Symptoms of traumatic grief assessed by the inventory of traumatic grief, current feelings of grief assessed by the Texas revised inventory of grief, and post-traumatic stress reactions assessed by the impact of event scale. The bereaved family and friends of cancer patients who died by euthanasia had less traumatic grief symptoms (adjusted difference -5.29 (95% confidence interval -8.44 to -2.15)), less current feeling of grief (adjusted difference 2.93 (0.85 to 5.01)); and less post-traumatic stress reactions (adjusted difference -2.79 (-5.33 to -0.25)) than the family and friends of patients who died of natural causes. These differences were independent of other risk factors. The bereaved family and friends of cancer patients who died by euthanasia coped better with respect to grief symptoms and post-traumatic stress reactions than the bereaved of comparable cancer patients who died a natural death. These results should not be interpreted as a plea for euthanasia, but as a plea for the same level of care and openness in all patients who are terminally ill.

Full Text Available Generally, deaf and hard of hearing (D/HH children have fewer friends than hearing peers and their friendships are of a lower quality. 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. In addition, the study examined whether the different friendship qualities were related to the participants' well-being. 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.

When experiencing mental health difficulties, university students turn to their friends for support. This study assessed the consequences of caregiving among a university sample, identifying predictors of caregiving burden among students. A total of 79 students with experience of supporting a friend with mental health difficulties were recruited through a UK student mental health charity to complete an online survey. Alongside qualitative data, the online survey used the Experience of Caregiving Inventory and the Involvement Evaluation Questionnaire as measures of the consequences of caregiving. Students supporting friends, housemates or partners were found to experience significant consequences of caregiving. Frequency of face-to-face contact and duration of illness predicted more negative consequences of caregiving, but these relationships were not straightforward. The presence and intensity of professional support did not influence the experience of caregiving. The study suggests that the impact of supporting friends with mental health difficulties is not insubstantial for students. Broadening the network of informal social support may help improve the experience for students supporting a friend, but currently, contact with professional services appears to have a limited effect. © 2017 John Wiley & Sons Australia, Ltd.

Supporting cystic fibrosis disease management during adolescence: the role of family and friends.

Barker, D H; Driscoll, K A; Modi, A C; Light, M J; Quittner, A L

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.

Friends-enemies: endogenous retroviruses are major transcriptional regulators of human DNA

Science.gov (United States)

Buzdin, Anton A.; Prassolov, Vladimir; Garazha, Andrew V.

2017-06-01

Endogenous retroviruses are mobile genetic elements hardly distinguishable from infectious, or “exogenous”, retroviruses at the time of insertion in the host DNA. Human endogenous retroviruses (HERVs) are not rare. They gave rise to multiple families of closely related mobile elements that occupy 8% of the human genome. Together, they shape genomic regulatory landscape by providing at least 320,000 human transcription factor binding sites (TFBS) located on 110,000 individual HERV elements. The HERVs host as many as 155,000 mapped DNaseI hypersensitivity sites, which denote loci active in the regulation of gene expression or chromatin structure. The contemporary view of the HERVs evolutionary dynamics suggests that at the early stages after insertion, the HERV is treated by the host cells as a foreign genetic element, and is likely to be suppressed by the targeted methylation and mutations. However, at the later stages, when significant number of mutations has been already accumulated and when the retroviral genes are broken, the regulatory potential of a HERV may be released and recruited to modify the genomic balance of transcription factor binding sites. This process goes together with further accumulation and selection of mutations, which reshape the regulatory landscape of the human DNA. However, developmental reprogramming, stress or pathological conditions like cancer, inflammation and infectious diseases, can remove the blocks limiting expression and HERV-mediated host gene regulation. This, in turn, can dramatically alter the gene expression equilibrium and shift it to a newer state, thus further amplifying instability and exacerbating the stressful situation.

The impact of Nordic countries' family friendly policies on employment, wages, and children

Gupta, Nabanita Datta; Smith, Nina; Verner, Mette

2008-01-01

-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......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...

Constructing alignments and phylogenies for a given locus from large genome sequencing studies with relevant outgroups allow novel evolutionary and anthropological insights. However, no user-friendly tool has been developed to integrate thousands of recently available and anthropologically relevant genome sequences to construct complete sequence alignments and phylogenies. Here, we provide VCFtoTree, a user friendly tool with a graphical user interface that directly accesses online databases to download, parse and analyze genome variation data for regions of interest. Our pipeline combines popular sequence datasets and tree building algorithms with custom data parsing to generate accurate alignments and phylogenies using all the individuals from the 1000 Genomes Project, Neanderthal and Denisovan genomes, as well as reference genomes of Chimpanzee and Rhesus Macaque. It can also be applied to other phased human genomes, as well as genomes from other species. The output of our pipeline includes an alignment in FASTA format and a tree file in newick format. VCFtoTree fulfills the increasing demand for constructing alignments and phylogenies for a given loci from thousands of available genomes. Our software provides a user friendly interface for a wider audience without prerequisite knowledge in programming. VCFtoTree can be accessed from https://github.com/duoduoo/VCFtoTree_3.0.0 .

Vaca, Federico E; Anderson, Craig L

2011-01-01

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.

Secrets from friends and parents: longitudinal links with depression and antisocial behavior.

Science.gov (United States)

Laird, Robert D; Bridges, Brittanee J; Marsee, Monica A

2013-08-01

Keeping secrets from parents is associated with depression and antisocial behavior. The current study tested whether keeping secrets from best friends is similarly linked to maladjustment, and whether associations between secrecy and maladjustment are moderated by the quality of the friendship. Adolescents (N = 181; 51% female, 48% white, non-Hispanic, 45% African American) reported their secrecy from parents and best friends, the quality of their parent-adolescent relationships and best friendships, and their depression and antisocial behavior at ages 12 and 13. Keeping more secrets from best friends was associated with more depression, but not with more antisocial behavior, when controlling for earlier adjustment, secrecy from parents, and the quality of the friendship. For girls associations between maladjustment and secrecy were conditioned by the quality of the relationships and whether secrets were kept from parents and friends. Discussion argues for expanding the study of secrecy in adolescence beyond the parent-child dyad. Copyright © 2013 The Foundation for Professionals in Services for Adolescents.

Antisocial boys and their friends in early adolescence: relationship characteristics, quality, and interactional process.

Science.gov (United States)

Dishion, T J; Andrews, D W; Crosby, L

1995-02-01

This study examines the close friendships of early adolescent boys in relation to antisocial behavior. 186 13-14-year-old boys and their close friends were interviewed, assessed at school, and videotaped in a problem-solving task. Similarity was observed between the demographic characteristics and antisocial behavior of the boys and their close friends. There was a tendency for the close friends of antisocial boys to live within the same neighborhood block and to have met in unstructured, unsupervised activities. Direct observations of interactions with close friends revealed a reliable correlation between antisocial behavior, directives, and negative reciprocity. Positive interactions within the friendship were uncorrelated with antisocial behavior and relationship quality. Implications of these findings for clinical and developmental theory are discussed.

Effect of Trajectories of Friends' and Parents' School Involvement on Adolescents' Engagement and Achievement.

Im, Myung Hee; Hughes, Jan N; West, Stephen G

2016-12-01

In a sample of 527 academically at-risk youth, we investigated trajectories of friends' and parents' school involvement across ages 12-14 and the joint contributions of these trajectories to adolescents' age 15 school engagement and academic achievement. Girls reported higher levels of friends' and parents' school involvement than boys. Both parents' and friends' school involvement declined across ages 12-14. Combined latent growth models and structural equation models showed effects of the trajectories of friends' and parents' school involvement on adolescents' age 15 school engagement and academic achievement, over and above adolescents' prior performance. These effects were additive rather than interactive. Strategies for enhancing parent involvement in school and students' affiliation with peers who are positively engaged in school are discussed.

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.

"Enjoy Your Sexuality, but Do it in Secret": Exploring Undergraduate Women's Reports of Friends' Sexual Communications.

Science.gov (United States)

Trinh, Sarah L

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.

Hamilton, Kyra; Warner, Lisa M; Schwarzer, Ralf

2017-02-01

Physical activity, including some form of vigorous activity, is a key component of a healthy lifestyle in young people. Self-efficacy and social support have been identified as key determinants of physical activity; however, the mechanism that reflects the interplay of these two factors is not well understood. The aim of the current study was to test social cognitive theory's notion that self-efficacy relates to intention that translates into behavior and to investigate whether friend support and self-efficacy synergize, interfere, or compensate for one another to predict vigorous physical activity in adolescents-a population at risk of rapid decreases in physical activity. A survey at two points in time was conducted in 226 students aged 12 to 16 years. In a conditional process analysis, friend support and physical activity self-efficacy were specified as interacting predictors of intention. The latter was specified as a mediator between self-efficacy and later vigorous physical activity, controlling for sex and age. Self-efficacy emerged as the dominant predictor of intention, followed by friend support, and an interaction between support and self-efficacy. In adolescents with high self-efficacy, intention was independent of support. In those with low self-efficacy, receiving friend support partly compensated for lack of self-efficacy. The effect of self-efficacy on vigorous physical activity was mediated by intention. Adolescent vigorous physical activity was indirectly predicted by self-efficacy via intention, and this mediation was further moderated by levels of friend support, indicating that friend support can partly buffer lack of self-efficacy.

Background Many older people are vulnerable with multiple health problems and need of extensive care and support for quality of life. 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 focus on older people’s health benefits and friendly services. PMID:26028980

The Angel and the Devil on your shoulder: Friends mitigate and exacerbate 21st birthday alcohol-related consequences.

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

The Behavior of Environmentally Friendly Corrosion Preventative Compounds in an Aggressive Coastal Marine Environment

Montgomery, Eliza L.; Calle, Luz Marina; Curran Jerome C.; Kolody, Mark R.

2013-01-01

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.

2013-12-01

In order to manufacture an eco-friendly stud, the sheared pattern is designed by the Taguchi method and expanded by the side rolls. The seven geometrical shape of sheared pattern are considered in the structural and thermal analyses to select the best functional one in terms of the durability and fire resistance of dry wall. For optimizing the size of the sheared pattern chosen, the L9 orthogonal array and smaller-the-better characteristics of the Taguchi method are used. As the roll gap causes forming defects when the upper-and-lower roll type is adopted for expanding the sheared pattern, the side roll type is introduced. The stress and strain distributions obtained by the FEM simulation of roll-forming processes are utilized for the design of expanding process. The expanding process by side rolls shortens the length of expanding process and minimizes the cost of dies. Furthermore, the stud manufactured by expanding the sheared pattern of the web is an eco-friend because of the scrapless roll-forming process. In addition, compared to the conventionally roll-formed stud, the material cost is lessened about 13.6% and the weight is lightened about 15.5%.

Three Degrees of Inclusion: the Gossip-Effect in Human Networks

Szekfu˝, Balázs; Szvetelszky, Zsuzsanna

2005-06-01

Using the scientific definition of gossip, an ancient and ubiquitous phenomenon of the social networks, we present our preliminary study and its results on how to measure the networks based on dissemination of connections and information. We try to accurately calculate the gossip-effects in networks with our hypothesis of "three degrees of inclusion". Our preliminary study on the subject of "three degrees of inclusion" gives latency to a very important property of social networks. Observing the human communication of closely knit social groups we came to the conclusion that the human networks are based on not more than three degrees of links. Taking the strong human ties into account our research indicates that whoever is on the fourth degree rarely counts as an in-group member. Our close friend's close friend's close friend — that is about the farthest — three steps — our network can reach out when it comes to telling a story or asking for a favor. Up to now no investigations have been performed to see whether the effects of gossip lead to the phase transition of the content of network's self-organizing communication. Our conclusion is that the gossip-effect must be considered as the prefactor of the news and opinions diffusion and dynamics at the social level.

Patients usually require long-term training for effective EEG-based brain-computer interface (BCI) control due to fatigue caused by the demands for focused attention during prolonged BCI operation. We intended to develop a user-friendly BCI requiring minimal training and less mental load. Testing of BCI performance was investigated in three patients with amyotrophic lateral sclerosis (ALS) and three patients with primary lateral sclerosis (PLS), who had no previous BCI experience. All patients performed binary control of cursor movement. One ALS patient and one PLS patient performed four-directional cursor control in a two-dimensional domain under a BCI paradigm associated with human natural motor behavior using motor execution and motor imagery. Subjects practiced for 5-10min and then participated in a multi-session study of either binary control or four-directional control including online BCI game over 1.5-2h in a single visit. Event-related desynchronization and event-related synchronization in the beta band were observed in all patients during the production of voluntary movement either by motor execution or motor imagery. The online binary control of cursor movement was achieved with an average accuracy about 82.1+/-8.2% with motor execution and about 80% with motor imagery, whereas offline accuracy was achieved with 91.4+/-3.4% with motor execution and 83.3+/-8.9% with motor imagery after optimization. In addition, four-directional cursor control was achieved with an accuracy of 50-60% with motor execution and motor imagery. Patients with ALS or PLS may achieve BCI control without extended training, and fatigue might be reduced during operation of a BCI associated with human natural motor behavior. The development of a user-friendly BCI will promote practical BCI applications in paralyzed patients. Copyright 2010 International Federation of Clinical Neurophysiology. All rights reserved.

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.

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.

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

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

2017-12-14

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.

2018-02-01

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.

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

Directory of Open Access Journals (Sweden)

Full Text Available 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.

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.

This study examines two sources of informal support-perceived family and friend support-and the psychological well-being-self-esteem, depression and loneliness-of 150 Chinese and 145 American elders. There were no significant differences between the elderly American and Chinese persons' mean scores on family and friend support. The multiple linear regression analyses with interaction terms (country x family support and country x friend support), however, indicated that the relationship between family support and depression and family support and loneliness was stronger for the Chinese elderly than the US elderly. Conversely, the relationship between friend support and depression and friend support and loneliness is stronger for US elderly than Chinese elderly. The implications of these findings for social work practice in both countries is discussed.

Lawrence, Estelle; Struthers, Patricia; Van Hove, Geert

2016-12-01

Despite an increase in HIV Counselling and Testing (HCT), few young people have been tested. It has been suggested that they do not test because formal health services (where HCT is provided) are often not youth friendly. The World Health Organisation describes a youth-friendly health service (YFHS) as one which is accessible, equitable, acceptable, appropriate, and effective. A mobile school-based model has been implemented by a non-governmental organisation in Cape Town in an attempt to make HCT more youth friendly and accessible to young people. The objective of this study was to explore whether this mobile school-based HCT service is youth friendly. The study was descriptive, using three qualitative data collection methods: observation of the HCT site at two secondary schools; interviews with six service providers; and direct observation of 21 HCT counselling sessions. The mobile school-based HCT service fulfilled some of the criteria for being a YFHS. The service was equitable in that all students, irrespective of race, gender, age, or socio-economic status, were free to use the service. It was accessible in terms of location and cost, but students were not well informed to make decisions about using the service. The service was acceptable in that confidentiality was guaranteed and the service providers were friendly and non-judgemental, but it was not considered acceptable in that there was limited privacy. The service was appropriate in that HCT is recommended as an intervention for decreasing the transmission of HIV, based on evidence and expert opinion; however, in this case, HCT was provided as a stand-alone service rather than part of a full package of services. Moreover, studies have suggested that young people want to know their HIV status. The service was ineffective in that it identified students who are HIV positive; however, these students were not assisted to access care. Providing HCT in the school setting may make HCT more accessible for

The Baby-Friendly Hospital Initiative requires hospitals to pay market price for infant formula. No studies have specifically examined the effect of hospitals paying for infant formula on breastfeeding mothers' exposure to Baby-Friendly steps. To investigate the effect of hospitals implementing a policy of paying for infant formula on new mothers' exposure to Baby-Friendly steps and examine the effect of exposure to Baby-Friendly steps on breastfeeding rates. We used a repeated prospective cohort study design. We recruited 2 cohorts of breastfeeding mother-infant pairs (n = 2470) in the immediate postnatal period from 4 Hong Kong public hospitals and followed them by telephone up to 12 months postpartum. We assessed participants' exposure to 6 Baby-Friendly steps by extracting data from the medical record and by maternal self-report. After hospitals began paying for infant formula, new mothers were more likely to experience 4 out of 6 Baby-Friendly steps. Breastfeeding initiation within the first hour increased from 28.7% to 45%, and in-hospital exclusive breastfeeding rates increased from 17.9% to 41.4%. The proportion of mothers who experienced all 6 Baby-Friendly steps increased from 4.8% to 20.5%. The risk of weaning was progressively higher among participants experiencing fewer Baby-Friendly steps. Each additional step experienced by new mothers decreased the risk of breastfeeding cessation by 8% (hazard ratio = 0.92; 95% CI, 0.89-0.95). After implementing a policy of paying for infant formula, breastfeeding mothers were exposed to more Baby-Friendly steps, and exposure to more steps was significantly associated with a lower risk of breastfeeding cessation. © The Author(s) 2015.

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.

Conventional, Partially Converted and Environmentally Friendly Farming in South Korea: Profitability and Factors Affecting Farmers’ Choice

Directory of Open Access Journals (Sweden)

Saem Lee

2016-07-01

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.

Griffiths, Kathleen M; Crisp, Dimity A; Barney, Lisa; Reid, Russell

2011-12-15

People with depression often seek help from family and friends and public health campaigns frequently encourage such help seeking behaviours. However, there has been little systematically collected empirical data concerning the effects of such informal help seeking. The current study sought to investigate the views of consumers about the advantages and disadvantages of seeking support from family and friends for depression. Participants were the subset of 417 respondents to a survey, sent to 7000 randomly selected members of an Australian electoral community, who indicated that they had sought help for depression from family or friends. One item on the survey asked participants to indicate the advantages or disadvantages of seeking help from family or friends. A coding system was developed based on a content analysis of the responses to the item. Each of the responses was then coded by two raters. Respondents identified both advantages and disadvantages of seeking support from friends. The most commonly cited advantage was social support (n = 282) including emotional support (n = 154), informational support (n = 93), companionship support (n = 36) and instrumental support (n = 23). Other advantages related to family's or friend's background knowledge of the person and their circumstances (n = 72), the opportunity to offload the burden associated with depression (n = 62), the personal attributes of family and friends (n = 49), their accessibility (n = 36), and the opportunity to educate family and friends and increase their awareness about the respondent's depression (n = 30). The most commonly cited disadvantages were stigma (n = 53), inappropriate support (n = 45), the family member's lack of knowledge, training and expertise (n = 32) and the adverse impact of the help seeking on the family/friend (n = 20) and the relationship (n = 18). Family and friends are well placed to provide support which consumers perceive to be positive and which can assist them in

Is the self always better than a friend? Self-face recognition in Christians and atheists.

Science.gov (United States)

Ma, Yina; Han, Shihui

2012-01-01

Early behavioral studies found that human adults responded faster to their own faces than faces of familiar others or strangers, a finding referred to as self-face advantage. Recent research suggests that the self-face advantage is mediated by implicit positive association with the self and is influenced by sociocultural experience. The current study investigated whether and how Christian belief and practice affect the processing of self-face in a Chinese population. Christian and Atheist participants were recruited for an implicit association test (IAT) in Experiment 1 and a face-owner identification task in Experiment 2. Experiment 1 found that atheists responded faster to self-face when it shared the same response key with positive compared to negative trait adjectives. This IAT effect, however, was significantly reduced in Christians. Experiment 2 found that atheists responded faster to self-face compared to a friend's face, but this self-face advantage was significantly reduced in Christians. Hierarchical regression analyses further showed that the IAT effect positively predicted self-face advantage in atheists but not in Christians. Our findings suggest that Christian belief and practice may weaken implicit positive association with the self and thus decrease the advantage of the self over a friend during face recognition in the believers.

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. 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). 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, ptelevision 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.

Inhibition of human placental aromatase activity by hydroxylated polybrominated diphenyl ethers (OH-PBDEs).

Polybrominated diphenyl ethers (PBDEs) are widely used as flame retardants in many different polymers, resins and substrates. Due to their widespread production and use, their high binding affinity to particles, and their lipophilic properties, several PBDE congeners can bioaccumulate in the environment. As a result, PBDEs and their hydroxylated metabolites (OH-PBDEs) have been detected in humans and various wildlife samples, such as birds, seals, and whales. Furthermore, certain OH-PBDEs and their methoxylated derivatives (MeO-PBDEs) are natural products in the marine environment. Recently, our laboratory focused on the possible effects on steroidogenesis of PBDEs and OH-PBDEs, e.g. in the human adrenocortical carcinoma (H295R) cell line indicating that some OH-PBDEs can significantly influence steroidogenic enzymes like CYP19 (aromatase) and CYP17. In the present study, human placental microsomes have been used to study the possible interaction of twenty two OH-PBDEs and MeO-PBDEs with aromatase, the enzyme that mediates the conversion of androgens into estrogens. All OH-PBDE derivates showed significant inhibition of placental aromatase activity with IC(50) values in the low micromolar range, while the MeO-PBDEs did not have any effect on this enzyme activity. Enzyme kinetics studies indicated that two OH-PBDEs, 5-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (5-OH-BDE47) and 6-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (6-OH-BDE47), had a mixed-type inhibition of aromatase activity with apparent K(i)/K(i)' of 7.68/0,02 microM and 5.01/0.04 microM respectively. For comparison, some structurally related compounds, a dihydroxylated polybrominated biphenyl, which is a natural product (2,2'-dihyroxy-3,3',5,5'-tetrabromobiphenyl (2,2'-diOH-BB80)) and its non-bromo derivative were also included in the study. Again inhibition of aromatase activity could be measured, but their potency was significantly less than those observed for the OH-PBDEs. These results show that a

Mechanism of inactivation of human leukocyte elastase by a chloromethyl ketone: kinetic and solvent isotope effect studies

Stein, R.L.; Trainor, D.A.

1986-01-01

The mechanism of inactivation of human leukocyte elastase (HLE) by the chloromethyl ketone MeOSuc-Ala-Ala-Pro-Val-CH 2 Cl was investigated. The dependence of the first-order rate constant for inactivation on concentration of chloromethyl ketone is hyperbolic and suggests formation of a reversible Michaelis complex prior to covalent interaction between the enzyme and inhibitor. However, the observed Ki value is 10 microM, at least 10-fold lower than dissociation constants for complexes formed from interaction of HLE with structurally related substrates or reversible inhibitors, and suggests that Ki is a complex kinetic constant, reflecting the formation and accumulation of both the Michaelis complex and a second complex. It is proposed that this second complex is a hemiketal formed from attack of the active site serine on the carbonyl carbon of the inhibitor. The accumulation of this intermediate may be a general feature of reactions of serine proteases and chloromethyl ketones derived from specific peptides and accounts for the very low Ki values observed for these reactions. The solvent deuterium isotope effect (SIE) on the inactivation step (ki) is 1.58 +/- 0.07 and is consistent with rate-limiting, general-catalyzed attack of the active site His on the methylene carbon of the inhibitor with displacement of chloride anion. The general catalyst is thought to be the active site Asp. In contrast, the SIE on the second-order rate constant for HLE inactivation, ki/Ki, is inverse and equals 0.64 +/- 0.05

The world has witnessed growing complexities in disease scenario influenced by the drastic changes in host-pathogen- environment triadic relation. Pharmaceutical R&Ds are in constant search of novel therapeutic entities to hasten transition of drug molecules from lab bench to patient bedside. Extensive animal studies and human pharmacokinetics are still the "gold standard" in investigational new drug research and bio-equivalency studies. Apart from cost, time and ethical issues on animal experimentation, burning questions arise relating to ecological disturbances, environmental hazards and biodiversity issues. Grave concerns arises when the adverse outcomes of continued studies on one particular disease on environment gives rise to several other pathogenic agents finally complicating the total scenario. Thus Pharma R&Ds face a challenge to develop bio-waiver protocols. Lead optimization, drug candidate selection with favorable pharmacokinetics and pharmacodynamics, toxicity assessment are vital steps in drug development. Simulation tools like Gastro Plus™, PK Sim®, SimCyp find applications for the purpose. Advanced technologies like organ-on-a chip or human-on-a chip where a 3D representation of human organs and systems can mimic the related processes and activities, thereby linking them to major features of human biology can be successfully incorporated in the drug development tool box. PBPK provides the State of Art to serve as an optional of animal experimentation. PBPK models can successfully bypass bio-equivalency studies, predict bioavailability, drug interactions and on hyphenation with in vitro-in vivo correlation can be extrapolated to humans thus serving as bio-waiver. PBPK can serve as an eco-friendly bio-waiver predictive tool in drug development. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

This study considered the unique and interactive roles of social norms from parents, friends and schools in predicting developmental trajectories of adolescent drinking and intoxication. Using data from the National Longitudinal Study of Adolescent Health, which followed adolescents (N = 18,921) for 13 years, we used discrete mixture modelling to identify unique developmental trajectories of drinking and of intoxication. Next, multilevel multinomial regression models examined the role of alcohol-related social norms from parents, friends and schoolmates in the prediction of youths' trajectory group membership. Results demonstrated that social norms from parents, friends and schoolmates that were favourable towards alcohol use uniquely predicted drinking and intoxication trajectory group membership. Interactions between social norms revealed that schoolmate drinking played an important moderating role, frequently augmenting social norms from parents and friends. The current findings suggest that social norms from multiple sources (parents, friends and schools) work both independently and interactively to predict longitudinal trajectories of adolescent alcohol use. Results highlight the need to identify and understand social messages from multiple developmental contexts in efforts to reduce adolescent alcohol consumption and alcohol-related risk-taking.

Children with medical conditions often experience a combination of positive and negative social interactions with parents and friends. Adult research examining cross-domain buffering effects has documented that supportive social ties can make up for shortcomings in other social relationships. This study examined whether negative effects of strained relationships with loved ones can be buffered when children feel supported by individuals in different support networks (i.e., cross-domain buffering effects). Children with Type I diabetes (n = 56), chronic asthma (n = 54), and cystic fibrosis (n = 17) completed questionnaires during an outpatient hospital visit that assessed perceptions of support and strain from parents and friends, quality of life, self-concept, and emotional/behavioral difficulties. Parental strain was conceptualized as parental overprotection and parental rejection. Hierarchical regression analyses showed that friend support buffered the adverse effects of parental strain on child quality of life, self-concept, and emotional/behavioral difficulties. Interestingly, parental support did not buffer the negative effects of experiencing strained relationships with friends; only main effects on outcome were found. These findings partially support our hypotheses of cross-domain buffering. In this study, friendships were a protective factor for children who experienced strained relationships with parents. In contrast, although parent support had a direct impact on child outcome, it did not make up for feeling rejected by friends. Because close relationships are often strained during medical stressors, findings underscore the importance of promoting social connectedness in chronically ill children to maximize opportunities for experiencing positive social relationships.

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.

The objective of this pilot study was to determine women's perceptions of their levels of maternal role competence at discharge from a Baby-Friendly hospital. A convenience sample of 30 women completed two self-report questionnaires: a demographic questionnaire and the Perceived Maternal Parenting Self-Efficacy scale. Women report that they perceived high levels of maternal role competence with a mean total score of 69.80 (standard deviation = 6.86) out of 80. As women experience breastfeeding in Baby-Friendly hospitals, maternal role competence may develop with appropriate support. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

This paper discusses the relationship of customers to the Space Station Program currently being defined by NASA. Emphasis is on definition of the Program such that the Space Station will be conducive to use by customers, that is by people who utilize the services provided by the Space Station and its associated platforms and vehicles. Potential types of customers are identified. Scenarios are developed for ways in which different types of customers can utilize the Space Station. Both management and technical issues involved in making the Station 'customer friendly' are discussed.

When friends disappoint: boys' and girls' responses to transgressions of friendship expectations.

MacEvoy, Julie Paquette; Asher, Steven R

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.

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

Hanging Out with Which Friends? Friendship-Level Predictors of Unstructured and Unsupervised Socializing in Adolescence.

Siennick, Sonja E; Osgood, D Wayne

2012-12-01

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.

Tang, Hao; Chen, Kunfeng; Li, Xiaonan; Ao, Man; Guo, Xinwen; Xue, Dongfeng

Halogen-free and environment-friendly magnesium hydroxide (Mg(OH)2) was synthesized to enhance the flame retardant properties of thermoplastic elastomer (TPE). When the Mg(OH)2 content was optimized to 35wt.%, the TPE-Mg(OH)2 composites exhibited the best flame retardant properties. The results showed that there was a delay of ignition time of the samples containing Mg(OH)2; compared with the samples without Mg(OH)2, the heat release rate and total heat release decrease by 31.4% and 35.6%, while total smoke production and mass loss rate reduce by 56% and 34.2%, respectively. This work opens a door to manufacture fire-resistant polymer-based composites with environmental-friendly flame retardant additives by controllable crystallization and chemical strategies.

This study examined the changes in friends' and parental influences on cigarette smoking across two developmentally distinct social environments for adolescents: junior high school and high school. Longitudinal data consisting of seven repeated measures following 1,001 adolescents from 7th to 12th grade was obtained from the Midwestern Prevention Project. A two-piece Growth Curve Model (GCM) was used to assess the growth trajectory of current cigarette use: one piece for the junior high school period, and the other for the high school period. Perceived friends' and parental cigarette use were each used as a time-varying covariate in separate GCMs. Effects of friends' and parental cigarette use remained significant on adolescent cigarette smoking across the two developmental periods. The magnitude of friends' effect was in general higher during junior high school than high school. The magnitude of the parental effect remained relatively stable between the two periods. However, decreasing trends in both effects were observed from 10th to 12th grade. Gender differences also emerged. Friends' and parental effects were greater for girls in their early high school years, whereas friends' effect decreased in magnitude among girls and increased among boys during high school. The transition from junior high school to high school represents an opportunity for interventions to counteract peer influence given that such influence appeared to be much weaker during this period. However, interventions should continue to target parents as their behavior remains influential through the end of high school. Copyright © 2013 Society for Adolescent Health and Medicine.

Larsen, Britta A; Strong, David; Linke, Sarah E

2014-06-01

Social integration predicts morbidity and mortality, but its relationships with specific health behaviors that could explain this relationship, such as physical activity, have not been established. Additionally, studies associating social integration with health have not distinguished between sources of social contact (family vs. friends), which could be differentially related to health. The purpose of this study was to examine the association between social integration and physical activity and to explore differences in family and friend social integration. Data came from the 2001 wave of the National Health Interview Survey. Adult participants (N = 33,326) indicated levels of social integration by reporting whether they had seen and/or called friends and/or family in the past 2 weeks and also reported their weekly minutes of physical activity. Logistic regression was used to determine odds of meeting physical activity (PA) guidelines (≥ 150 min/week) and odds of inactivity (0 min/week) based on levels of social integration. Greater integration predicted higher odds of meeting PA guidelines and lower odds of inactivity after controlling for sociodemographic variables. This association was stronger and dose-dependent for integration with friends, whereas moderate family contact predicted greater activity than high levels of family contact. Those who are more socially integrated, particularly with friends rather than family, are also more physically active, which could partially explain the link between social integration and morbidity and mortality. Future studies examining this association should distinguish between sources of integration and explore why and how contact with friends vs. family is differentially associated with health behaviors.

Many adults suffering from mental disorders never receive the care they need. The role of family and friends in overcoming mental health treatment barriers is poorly understood. We investigated the association between awareness of lifetime mental health treatment history in one's family or friends, and likelihood of having recently received mental health care for oneself. Using Canadian Community Health Survey 2012-Mental Health data, we defined care seekers as individuals who talked about mental health issues to at least one health professional in the past 12 months. Seekers were matched to non-seekers based on estimated care seeking propensity, and 1933 matched pairs were created. Reported awareness of lifetime treatment history in family and friends was compared between seekers and non-seekers. There were no differences in the distribution of any confounder of interest between seekers and non-seekers. 73% of seekers were aware of treatment history in family or friends, compared to only 56% of non-seekers (RR 1.3; 95% CI 1.2, 1.3). Awareness of treatment history in family members had nearly identical associations with care seeking as awareness of treatment history in friends. We have found a social clustering of mental health care seeking behavior; individuals who were aware of lifetime treatment history in family or friends were more likely to have recently sought care for themselves. These novel results are consistent with a social learning model of care seeking behavior, and could inform efforts to bridge the current mental health treatment gap.

John F Helliwell

Full Text Available A recent large Canadian survey permits us to compare face-to-face ('real-life' and on-line social networks as sources of subjective well-being. The sample of 5,000 is drawn randomly from an on-line pool of respondents, a group well placed to have and value on-line friendships. We find three key results. First, the number of real-life friends is positively correlated with subjective well-being (SWB even after controlling for income, demographic variables and personality differences. Doubling the number of friends in real life has an equivalent effect on well-being as a 50% increase in income. Second, the size of online networks is largely uncorrelated with subjective well-being. Third, we find that real-life friends are much more important for people who are single, divorced, separated or widowed than they are for people who are married or living with a partner. Findings from large international surveys (the European Social Surveys 2002-2008 are used to confirm the importance of real-life social networks to SWB; they also indicate a significantly smaller value of social networks to married or partnered couples.

Modeling Age-Friendly Environment, Active Aging, and Social Connectedness in an Emerging Asian Economy

Full Text Available This paper empirically tested eight key features of WHO guidelines to age-friendly community by surveying 211 informal caregivers and 402 self-care adults (aged 45 to 85 and above in Malaysia. We examined the associations of these eight features with active aging and social connectedness through exploratory and confirmatory factor analyses. A structural model with satisfactory goodness-of-fit indices (CMIN/df = 1.11, RMSEA = 0.02, NFI = 0.97, TLI = 1.00, CFI = 1.00, and GFI = 0.96 indicates that transportation and housing, community support and health services, and outdoor spaces and buildings are statistically significant in creating an age-friendly environment. We found a statistically significant positive relationship between an age-friendly environment and active aging. This relationship is mediated by social connectedness. The results indicate that built environments such as accessible public transportations and housing, affordable and accessible healthcare services, and elderly friendly outdoor spaces and buildings have to be put into place before social environment in building an age-friendly environment. Otherwise, the structural barriers would hinder social interactions for the aged. The removal of the environmental barriers and improved public transportation services provide short-term solutions to meet the varied and growing needs of the older population.

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 role of gender and friends' gender on peer socialization of adolescent drinking: a prospective multilevel social network analysis.

Deutsch, Arielle R; Steinley, Douglas; Slutske, Wendy S

2014-09-01

Although socializing effects of friends' drinking on adolescent drinking behavior have been firmly established in previous literature, study results on the importance of gender, as well as the specific role that gender may play in peer socialization, are very mixed. Given the increasing importance of gender in friendships (particularly opposite-sex friendships) during adolescence, it is necessary to better understand the nuanced roles that gender can play in peer socialization effects on alcohol use. In addition, previous studies focusing on the interplay between individual gender and friends' gender have been largely dyadic; less is known about potential gendered effects of broader social networks. The current study sought to further investigate potential effects of gender on friends' influence on adolescent drinking behavior with particular emphasis on the number of same-sex and opposite-sex friends within one's friendship network, as well as closeness to these friends. Using Waves I and II of the saturated sample of the National Longitudinal Study of Adolescent Health (Add Health), adolescent friendship networks were used to calculate the mean drinking behaviors of adolescent friends. Multi-level models estimated the effects of individual drinking behaviors, friend drinking behaviors, and school-level drinking behaviors on adolescent drinking 1 year later, as well as moderating effects of gender composition of friendship groups and male and female friend closeness on the relationship between friends' drinking behaviors and adolescent drinking behavior. Results documented that gender composition of friendship groups did not influence the effect of friends' drinking on individual drinking 1 year later. However, closeness to friends did influence this relationship. As closeness to male friends decreased, the influence of their drinking behavior increased, for both boys and girls. A similar effect was found for female friends, but only for boys. Female friend

The relation of close friends to cognitive performance in old age: the mediating role of leisure activities.

ABSTRACTBackground:From a conceptual point of view, close friends are an important resource for promoting activity engagement in old age. Leisure activity engagement in turn is a key predictor of cognitive performance. Empirically, it remains unclear so far whether leisure activity engagement mediates between having close friends on the one hand and cognitive performance on the other, which we investigated in a large sample of older adults. We assessed cognitive performance (Mill Hill vocabulary scale and Trail Making Test (TMT) parts A and B) in 2,812 older adults. Participants reported information on leisure activity engagement and close friends. A larger number of leisure activities and a larger number of close friends were significantly related to better cognitive performance in the Mill Hill vocabulary scale and TMT parts A and B. A larger number of close friends were significantly related to a larger number of leisure activities. The number of leisure activities mediated more than half of the relation of the number of close friends to performance in all three cognitive measures. Having close friends may be helpful to stimulate and promote activity participation in old age. By enhancing individuals' cognitive reserve, this may finally preserve their cognitive performance level in old age.

Zhao, Jingxin; Liu, Xia; Wang, Meifang

2015-10-01

Using cross-sectional data from rural left-behind children aged 10-17 years in the Henan Province of China, the present study examined the roles of father-child cohesion, mother-child cohesion, and friend companionship in emotional adaptation (loneliness, depression, and life satisfaction) among children left behind by both of their rural-to-urban migrant parents compared to those with only a migrating father. The results indicated that the children with two migrating parents were disadvantaged according to their demonstration of depression but not in loneliness or life satisfaction. Both parent-child cohesion and friend companionship were directly associated with, to varying extents, the left-behind children's emotional outcomes. Moreover, friend companionship moderated the association between father-child cohesion and emotional outcomes among children with two migrating parents, but the moderating effects of friend companionship did not exist among children with only a migrating father. The implications of these findings for interventions directed at left-behind children are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

A mobile school-based HCT service – is it youth friendly?

Directory of Open Access Journals (Sweden)

Estelle Lawrence

2016-01-01

Full Text Available Background: Despite an increase in HIV Counselling and Testing (HCT, few young people have been tested. It has been suggested that they do not test because formal health services (where HCT is provided are often not youth friendly. The World Health Organisation describes a youth-friendly health service (YFHS as one which is accessible, equitable, acceptable, appropriate, and effective. A mobile school-based model has been implemented by a non-governmental organisation in Cape Town in an attempt to make HCT more youth friendly and accessible to young people. The objective of this study was to explore whether this mobile school-based HCT service is youth friendly. Methods: The study was descriptive, using three qualitative data collection methods: observation of the HCT site at two secondary schools; interviews with six service providers; and direct observation of 21 HCT counselling sessions. Key Results: The mobile school-based HCT service fulfilled some of the criteria for being a YFHS. The service was equitable in that all students, irrespective of race, gender, age, or socio-economic status, were free to use the service. It was accessible in terms of location and cost, but students were not well informed to make decisions about using the service. The service was acceptable in that confidentiality was guaranteed and the service providers were friendly and non-judgemental, but it was not considered acceptable in that there was limited privacy. The service was appropriate in that HCT is recommended as an intervention for decreasing the transmission of HIV, based on evidence and expert opinion; however, in this case, HCT was provided as a stand-alone service rather than part of a full package of services. Moreover, studies have suggested that young people want to know their HIV status. The service was ineffective in that it identified students who are HIV positive; however, these students were not assisted to access care. Conclusion: Providing HCT

Fitzgerald, Amanda; Fitzgerald, Noelle; Aherne, Cian

2012-08-01

This systematic review investigated the relationship between peer and/or friend variables and physical activity among adolescents by synthesising cross-sectional, longitudinal, and experimental research conducted in the US. Seven electronic databases were searched to identify related articles published within the last 10 years and the articles reviewed included adolescents between 10 and 18 years. Studies reporting a measure of physical activity for adolescents and at least one potential peer and/or friend variable were included. Research demonstrated that peers and friends have an important role to play in the physical activity behavior of adolescents. Six processes were identified through which peers and/or friends may have an influence on physical activity including: peer and/or friend support, presence of peers and friends, peer norms, friendship quality and acceptance, peer crowds, and peer victimization. The theoretical significance of these results is assessed and the development of peer-related physical activity programs for adolescents is discussed.

Haney, S.W.; Freidberg, J.P.; Solomon, C.J.

1995-01-01

Using variational techniques, we have developed a fast, user-friendly code for computing approximate, but highly accurate fixed boundary magnetohydrodynamic equilibria for tokamak plasmas. The variational procedure simplifies the problem---a two-dimensional nonlinear partial differential equation---to a set of nonlinear algebraic equations. The reduced problem can be readily solved on workstations or personal computers. This allows us to exploit sophisticated graphical user interfaces that make supplying calculation data and viewing results easy. This ease-of-use, along with the semianalytic nature of our calculation, allows researchers to routinely incorporate equilibrium information into their work. It also provides a tool for educators teaching fusion theory. We describe the variational formulation, the speed and accuracy of the computer implementation, and the design and operation of a user-friendly graphical interface

Full Text Available With social development, requirements on the spiritual and material life have increased. However, some environmental issues appear, for example, in food packaging. Application of environment-friendly materials in food packaging has been more and more attractive. This study analyses the characteristics of degradable food packaging material and the existing problems, proposes the manufacturing of food packaging with poly(lactic acid/nanocrystalline cellulose composite material, tests its thermal and mechanical properties, and applies it to the design of food packaging. The results demonstrate that the thermal and mechanical properties of the material could satisfy the requirements of food packaging and that the material is applicable to the design of food packaging in the future. This work provides a reference for the application of green, environment-friendly materials in the design of food packaging.

Mahon, Noreen E; Yarcheski, Adela

2017-04-01

The purpose of this study was to conduct two meta-analyses. The first examined social support from parents in relation to adolescent hope, and the second examined social support from friends in relation to adolescent hope. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for the literature reviewed, nine published studies or doctoral dissertations completed between 1990 and 2014 met the inclusion criteria. Using meta-analytic techniques and the mean weighted r statistic, the results indicated that social support from friends had a stronger mean effect size (ES = .31) than social support from parents (ES = .21); there was a statistically significant difference between the two ESs. Two of the four moderators for the parent social support-adolescent hope relationship were statistically significant. They were quality score and health status. Implications for school nurses and nurses in all settings are addressed, and conclusions are drawn based on the findings.

Robinson, Sarah; Davey, Barbara; Murrells, Trevor

2003-01-01

While European Union policy emphasises that one of the aims of family-friendly working arrangements is to increasing gender equality, in the UK the focus has been primarily on workforce retention. Drawing on a study of Registered General Nurses who returned to work after breaks for maternity leave, this paper considers their preferences and experiences in light of current UK family-friendly policies and the implications of the findings for increasing gender equality. Questionnaires were completed by respondents in three regional health authorities and focused on the four to eight year period after qualification. The following topics were investigated: views about length of maternity break and reasons for returning to work sooner than preferred; hours sought after a return and hours obtained; the availability of preferred patterns of work and of flexible hours; retention of grade on return; the availability and use of workplace crèches, and childcare arrangements when children were unwell.

2015-10-01

We tested whether effects of the Strengthening Families Program for Youth 10-14 (SFP10-14) diffused from intervention participants to their friends. We also tested which program effects on participants accounted for diffusion. Data are from 5,449 students (51% female; mean initial age = 12.3 years) in the PROmoting School-community-university Partnerships to Enhance Resilience community intervention trial (2001-2006) who did not participate in SFP10-14 (i.e., nonparticipants). At each of five waves, students identified up to seven friends and self-reported past month drunkenness and cigarette use, substance use attitudes, parenting practices, and unsupervised time spent with friends. We computed two measures of indirect exposure to SFP10-14: total number of SFP-attending friends at each wave and cumulative proportion of SFP-attending friends averaged across the current and all previous post-intervention waves. Three years post-intervention, the odds of getting drunk (odds ratio = 1.4) and using cigarettes (odds ratio = 2.7) were higher among nonparticipants with zero SFP-attending friends compared with nonparticipants with three or more SFP-attending friends. Multilevel analyses also provided evidence of diffusion: nonparticipants with a higher cumulative proportion of SFP-attending friends at a given wave were less likely than their peers to use drugs at that wave. Effects from SFP10-14 primarily diffused through friendship networks by reducing the amount of unstructured socializing (unsupervised time that nonparticipants spent with friends), changing friends' substance use attitudes, and then changing nonparticipants' own substance use attitudes. Program developers should consider and test how interventions may facilitate diffusion to extend program reach and promote program sustainability.

Nikken, Peter; de Graaf, Hanneke

2013-11-01

Research has argued that adolescents are at risk for harmful effects of sexual media, but little is known about the role of parents and friends on adolescents' media use in regard of these effects. The present two-wave study investigated whether prior parental and friends' influences on adolescents' use of sexual media shape their sexual attitudes and behaviors, and vice versa if prior sexual attitudes and behaviors predict parental and friends' media mediation. At two measurement points 18 months apart, 528 adolescents (12-17 years; 51.3% girls) reported on permissive sexual attitudes, sexual experience, perceived parental and friends' mediation of sexual media use, and communication with parents and friends about sex. Structural Equation Modeling shows that parents' mediation activities on adolescents' media use were not followed by less sexual experience and less permissive attitudes. On the contrary, parental restrictive mediation of girls' media use unexpectedly was followed by somewhat more sexual experience. Friends' interventions with media use did not predict adolescents' sexual experience and attitudes neither. Inverse relationships showed that prior sexual experience was followed by less restrictive parental mediation among boys, and both among boys and girls that permissive sexual attitudes were followed by less restrictive and less active parental mediation. At the same time, sexually more experienced and more permissive boys and girls did report more media pressure from and sexual communication with their friends later on. Our study thus indicates that the opposite agent roles of parents and friends for adolescents also applies to their usage of sexual media.

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

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.

Chen, Xi; McElwain, Nancy L; Lansford, Jennifer E

2017-12-20

Using data from a subsample of 913 study children and their friends who participated in the NICHD Study of Early Child Care and Youth Development, the interactive contributions of child-reported attribution biases and teacher-reported child emotional intensity (EI) at Grade 4 (M = 9.9 years) to observed child-friend interaction at Grade 6 (M = 11.9 years) were examined. Study children's hostile attribution bias, combined with high EI, predicted more negative child-friend interaction. In contrast, benign attribution bias, combined with high EI, predicted more positive child-friend interaction. The findings are discussed in light of the "fuel" interpretation of EI, in which high-intensity emotions may motivate children to act on their cognitive biases for better or for worse. © 2017 The Authors.

This study extends research on receptivity to tobacco marketing over a key developmental period for cigarette smoking experimentation. The purpose of this study was to understand the effect of receptivity to tobacco marketing and exposure to friends who smoke on smoking experimentation. Participants were 10 to 13 years old who had never tried cigarettes (n = 878), interviewed six times at 8-month intervals. At baseline, 25% percent of the 10 and 11 years old in the sample of never smokers were receptive to tobacco marketing, while less than 5% had friends who smoked. Having a friend who smoked at study baseline and acquiring such friends for the first time during the study were the strongest predictors of smoking experimentation. Initial receptivity to tobacco marketing increased the risk of smoking experimentation independently of having friends who smoke at baseline or acquiring friends who smoke throughout the study period. The high level of receptivity observed even among 10 and 11 years old and its robust relationship with cigarette smoking experimentation independent of the significant risk associated with having friends who smoke suggests that successful prevention of receptivity may require intervention at an early age.

Creation of an Innovation-Friendly Environment

Directory of Open Access Journals (Sweden)

Augustinas Maceika

2014-06-01

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.

Societal embedding of climate-friendly innovations

International Nuclear Information System (INIS)

Vaeyrynen, E.; Kivisaari, Sirkku; Lovio, R.

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.

Of the four most important atmospheric greenhouse gasses (GHG) enriched through human activities, only nitrous oxide (N2O) emissions are due primarily to agriculture. However, reductions in the application of synthetic N fertilizers could have significant negative consequences for a growing world population given the crucial role that these fertilizers have played in cereal yield increases since WWII. Increasing N use efficiency (NUE) through precision management of agricultural N in space and time will therefore play a central role in the reduction of agricultural N2O emissions. Precision N management requires a greater understanding of the spatio-temporal variability of factors supporting N management decisions such as crop yield, water and N availability, utilization and losses. We present an overview of a large, collaborative, multi-disciplinary project designed to improve our basic understanding of nitrogen (N), carbon (C) and water (H2O) spatio-temporal dynamics for wheat-based cropping systems on complex landscapes, and develop management tools to optimize water- and nitrogen-use efficiency for these systems and landscapes. Major components of this project include: (a) cropping systems experiments addressing nitrogen application rate and seeding density for different landscape positions; (b) GHG flux experiments and monitoring; (c) soil microbial genetics and stable isotope analyses to elucidate biochemical pathways for N2O production; (d) proximal soil sensing for construction of detailed soil maps; (e) LiDAR and optical remote sensing for crop growth monitoring; (f) hydrologic experiments, monitoring, and modeling; (g) refining the CropSyst simulation model to estimate biophysical processes and GHG emissions under a variety of management and climatic scenarios; and (h) linking farm-scale enterprise budgets to simulation modeling in order to provide growers with economically viable site-specific climate-friendly farming guidance.

Based on clinical presentation, glioblastoma (GBM) is stratified into primary and secondary types. The protein 53 (p53) pathway is functionally incapacitated in most GBMs by distinctive type-specific mechanisms. To model human gliomagenesis, we used a GFAP-HRas(V12) mouse model crossed into the p53ER(TAM) background, such that either one or both copies of endogenous p53 is replaced by a conditional p53ER(TAM) allele. The p53ER(TAM) protein can be toggled reversibly in vivo between wild-type and inactive conformations by administration or withdrawal of 4-hydroxytamoxifen (4-OHT), respectively. Surprisingly, gliomas that develop in GFAP-HRas(V12);p53(+/KI) mice abrogate the p53 pathway by mutating p19(ARF)/MDM2 while retaining wild-type p53 allele. Consequently, such tumors are unaffected by restoration of their p53ER(TAM) allele. By contrast, gliomas arising in GFAP-HRas(V12);p53(KI/KI) mice develop in the absence of functional p53. Such tumors retain a functional p19(ARF)/MDM2-signaling pathway, and restoration of p53ER(TAM) allele triggers p53-tumor-suppressor activity. Congruently, growth inhibition upon normalization of mutant p53 by a small molecule, Prima-1, in human GBM cultures also requires p14(ARF)/MDM2 functionality. Notably, the antitumoral efficacy of p53 restoration in tumor-bearing GFAP-HRas(V12);p53(KI/KI) animals depends on the duration and frequency of p53 restoration. Thus, intermittent exposure to p53ER(TAM) activity mitigated the selective pressure to inactivate the p19(ARF)/MDM2/p53 pathway as a means of resistance, extending progression-free survival. Our results suggest that intermittent dosing regimes of drugs that restore wild-type tumor-suppressor function onto mutant, inactive p53 proteins will prove to be more efficacious than traditional chronic dosing by similarly reducing adaptive resistance.

Control of heme synthesis during Friend cell differentiation: role of iron and transferrin

International Nuclear Information System (INIS)

Laskey, J.D.; Ponka, P.; Schulman, H.M.

In many types of cells the synthesis of σ-aminolevulinic acid (ALA) limits the rate of heme formation. However, results from this laboratory with reticulocytes suggest that the rate of iron uptake from 125 I-transferrin (Tf), rather than ALA synthase activity, limits the rate of heme synthesis in erythroid cells. To determine whether changes occur in iron metabolism and the control of heme synthesis during erythroid cell development Friend erythroleukemia cells induced to erythroid differentiation by dimethylsulfoxide (DMSO) were studied. While added ALA stimulated heme synthesis in uninduced Friend cells (suggesting ALA synthase is limiting) it did not do so in induced cells. Therefore the possibility was investigated that, in induced cells, iron uptake from Tf limits and controls heme synthesis. Several aspects of iron metabolism were investigated using the synthetic iron chelator salicylaldehyde isonicotinoyl hydrazone (SIH). Both induced and uninduced Friend cells take up and utilize Fe for heme synthesis directly from Fe-SIH without the involvement of transferrin and transferrin receptors and to a much greater extent than from saturating levels or 59 Fe-Tf (20 μM). Furthermore, in induced Friend cells 100 μM Fe-SIH stimulated 2- 14 C-glycine incorporation into heme up to 3.6-fold as compared to the incorporation observed with saturating concentrations of Fe-Tf. These results indicate that some step(s) in the pathway of iron from extracellular Tf to protoporphyrin, rather than the activity of ALA synthase, limits and controls the overall rate of heme and possibly hemoglobin synthesis in differentiating Friend erythroleukemia cells

FRIEND: a brain-monitoring agent for adaptive and assistive systems.

Science.gov (United States)

Morris, Alexis; Ulieru, Mihaela

2012-01-01

This paper presents an architectural design for adaptive-systems agents (FRIEND) that use brain state information to make more effective decisions on behalf of a user; measuring brain context versus situational demands. These systems could be useful for alerting users to cognitive workload levels or fatigue, and could attempt to compensate for higher cognitive activity by filtering noise information. In some cases such systems could also share control of devices, such as pulling over in an automated vehicle. These aim to assist people in everyday systems to perform tasks better and be more aware of internal states. Achieving a functioning system of this sort is a challenge, involving a unification of brain- computer-interfaces, human-computer-interaction, soft-computin deliberative multi-agent systems disciplines. Until recently, these were not able to be combined into a usable platform due largely to technological limitations (e.g., size, cost, and processing speed), insufficient research on extracting behavioral states from EEG signals, and lack of low-cost wireless sensing headsets. We aim to surpass these limitations and develop control architectures for making sense of brain state in applications by realizing an agent architecture for adaptive (human-aware) technology. In this paper we present an early, high-level design towards implementing a multi-purpose brain-monitoring agent system to improve user quality of life through the assistive applications of psycho-physiological monitoring, noise-filtering, and shared system control.

2016-04-01

Full Text Available Awareness of wheat farmers’ personal preferences towards environmental issues and weed types is important in pricing bioherbicides for sustainable weed management and could consequently be a fundamental guide to agricultural authorities and policy-makers. In the present study, a survey was carried out by using data collected from 180 wheat farmers of Korasan Razavi province during 2008, together with hedonic pricing method. The role of environmental qualitative factors and weed type on pricing environmental-friendly herbicides on the basis of “willingness to pay” was studied. Results from the estimation of hedonic pricing method indicated that reduction of water pollution, human health risk, farmers information about negative effects of chemical herbicides and the virtual variable of weed type had significant effects on pricing environmental friendly herbicides. Variables of soil pollution and weed perenniality had no significant effects on pricing herbicide applicable to sustainable agricultural systems. Based on the results of this study, possibilities of using bioherbicide or less pollutant herbicides and also the rate of farmers willingness to pay for alternatives in the region are important factors recommended for additional studies

Using environment friendly finely divided materials in brittle matrix composites

Rizwan, S.A.; Ahmad, H.

2005-01-01

Material engineers the world over are increasingly recommending the use of environment friendly efficient construction materials, which otherwise would have been classed as waste materials for improving the durability of concrete. Pakistan has been blessed by nature with huge natural resources of lime, and fly-ash is also becoming increasingly available with the induction of thermal power generation plants. To introduce the benefits of such concrete modifying materials to the engineering community in our country, an investigation has been carried out on the use of locally available powdered hydrated lime, fly-ash and their combinations in making concretes with a view to evaluate their strength, workability, durability and cost effectiveness. As such there is no documented data of local materials available on the topic in Pakistan. ACI mentions powdered hydrated lime and fly-ash as finely divided admixtures which can be used to improve concrete properties at microstructure level. It is commonly believed by the engineers that the use of such materials is especially desirable for durability purposes. Moreover, lime when added in concrete absorbs CO/sub 2/ from the environment thus making it friendly flexible material. he results of investigation are encouraging especially when the two were used in combination as some weight fraction of cement to make quality and environment friendly concrete.

Rulison, Kelly L.; Feinberg, Mark; Gest, Scott D.; Osgood, D. Wayne

2015-01-01

Purpose We tested whether effects of the Strengthening Families Program for Youth 10–14 (SFP10–14) diffused from intervention participants to their friends. We also tested which program effects on participants accounted for diffusion. Methods Data are from 5,449 students (51% female; mean initial age=12.3 years) in the PROSPER community intervention trial (2001–2006) who did not participate in SFP10–14 (i.e., non-participants). At each of 5 waves, students identified up to 7 friends and self-reported past month drunkenness and cigarette use, substance use attitudes, parenting practices, and unsupervised time spent with friends. We computed two measures of indirect exposure to SFP10–14: total number of SFP-attending friends at each wave and cumulative proportion of SFP-attending friends averaged across the current and all previous post-intervention waves. Results Three years post-intervention, the odds of getting drunk (OR=1.4) and using cigarettes (OR=2.7) were higher among non-participants with 0 SFP-attending friends compared to non-participants with 3 or more SFP-attending friends. Multilevel analyses also provided evidence of diffusion: non-participants with a higher cumulative proportion of SFP-attending friends at a given wave were less likely than their peers to use drugs at that wave. Effects from SFP10–14 primarily diffused through friendship networks by reducing the amount of unstructured socializing (unsupervised time that non-participants spent with friends), changing friends’ substance use attitudes, and then changing non-participants’ own substance use attitudes. Conclusions Program developers should consider and test how interventions may facilitate diffusion to extend program reach and promote program sustainability. PMID:26210856

2015-03-01

Although self-rated personality traits predict mortality risk, no study has examined whether one's friends can perceive personality characteristics that predict one's mortality risk. Moreover, it is unclear whether observers' reports (compared with self-reports) provide better or unique information concerning the personal characteristics that result in longer and healthier lives. To test whether friends' reports of personality predict mortality risk, we used data from a 75-year longitudinal study (the Kelly/Connolly Longitudinal Study on Personality and Aging). In that study, 600 participants were observed beginning in 1935 through 1938, when they were in their mid-20s, and continuing through 2013. Male participants seen by their friends as more conscientious and open lived longer, whereas friend-rated emotional stability and agreeableness were protective for women. Friends' ratings were better predictors of longevity than were self-reports of personality, in part because friends' ratings could be aggregated to provide a more reliable assessment. Our findings demonstrate the utility of observers' reports in the study of health and provide insights concerning the pathways by which personality traits influence health. © The Author(s) 2015.

2018-03-01

This paper presents the development of an operational forecasting service focusing on human-biometeorological conditions. The service is based on the coupling of numerical weather prediction models with an advanced human-biometeorological model. Human thermal perception and stress forecasts are issued on a daily basis for Greece, in both point and gridded format. A user-friendly presentation approach is adopted for communicating the forecasts to the public via the worldwide web. The development of the presented service highlights the feasibility of replacing standard meteorological parameters and/or indices used in operational weather forecasting activities for assessing the thermal environment. This is of particular significance for providing effective, human-biometeorology-oriented, warnings for both heat waves and cold outbreaks.

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.

Marriage work in older couples: Disclosure of marital problems to spouses and friends over time.

Science.gov (United States)

Jensen, Jakob F; Rauer, Amy J

2015-10-01

This study examined the frequency and impact of "marriage work" (MW), or the act of discussing marital problems with spouses and friends, among a sample of older married couples (N = 64). Using actor-partner interdependence models, we examined how turning to one's spouse and one's friend was linked to changes in both spouses' marital satisfaction and conflict 1 year later. We also investigated whether satisfaction and conflict predicted change in MW for older spouses. Both wives and husbands engaged in more MW with spouses than with friends, and only husbands' MW with spouses decreased over time. Wives' MW with spouses was associated with decreased marital satisfaction for husbands, whereas husbands' MW with spouses was linked with increased satisfaction for husbands. Furthermore, wives' MW with spouses predicted increases in wives' marital conflict over time. When examining effects in the opposite direction, wives' marital satisfaction predicted decreases in wives' MW with spouse. Husbands' satisfaction was linked with increases in wives' MW with spouses, increases in wives' MW with friends, and decreases in husbands' MW with friends. Finally, husbands' conflict predicted increases in husbands' MW with friends. Findings suggest that openly engaging in discussions of marital problems may not be as uniformly helpful for aging couples as it is for their younger counterparts. Given that many older adults tend to actively avoid conflictual interactions in an attempt to maximize emotional rewards, researchers and clinicians should note that traditional approaches to working through romantic conflict may not be ideal for aging couples.

Ukrainian realities of labeling of environmentally friendly products

I.M. Tsaruk

2016-12-01

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.

Obaidurrahman, K.; Singh, Om Pal

2009-01-01

When viewed from a large set of criteria such as abundance of energy resources, environmental impacts, low fuel inventory, quantum of waste generated and green house gas emissions, nuclear power can be considered as a large scale sustainable energy source. Among all energy sources, nuclear energy has perhaps the lowest impact on the environment, especially in relation to kilowatt-hr produced, because nuclear plants do not emit harmful gases and produce small quantity of waste. In other words, nuclear energy is the most environmental friendly electricity source. There are no significant adverse effects to water, land, habitat, species and air resources. The present paper discusses the sustainability and feasibility of nuclear power as an eco friendly energy source in the changing and challenging competitive power market. (author)

2013-12-01

This study examined the association between types of loss (i.e., sibling or close friend) and relationship quality (i.e., depth and conflict) with complicated grief, depression, somatic symptoms, and world assumptions in bereaved young adults. Participants were 107 young adults aged 17-29 years who were either bereaved or had never experienced a loss. Among bereaved participants, 66 lost a close friend and seven lost a sibling within the past 3 years (M = 1.63 years). Nineteen percent of the young adults met criteria for complicated grief and 31% had mild to severe depression. Participants with a deceased sibling reported greater depth in the relationship as compared to those who lost a friend. They were also more likely to have complicated grief (57% versus 15%) and report significantly higher levels of grief, depression, and somatic symptoms. Those who lost a sibling reported a lower sense of meaningfulness and benevolence of the world and self-worth as compared with those who lost a close friend or had not experienced a loss. Complicated grief and depression are common among bereaved young adults. Sibling loss is particularly distressing to young adults, due in part to the high level of relationship depth, and is associated with increased psychological and physical symptoms postloss. © 2013 Wiley Periodicals, Inc.

Massengale, Kelley E. C.; Ma, Alice; Rulison, Kelly L.; Milroy, Jeffrey J.; Wyrick, David L.

2017-01-01

Objective To describe first-year college student-athletes’ friendship contexts and test whether their perceptions of alcohol use and approval by different types of friends are associated with their own alcohol use. Participants First-year student-athletes (N=2,622) from 47 colleges and universities participating in National Collegiate Athletic Association (NCAA) sports during February–March 2013. Methods Student-athletes completed online surveys during the baseline assessment of an alcohol and other drug prevention program evaluation. Analyses tested whether perceptions of friends’ alcohol use (descriptive norms) and perceptions of friends’ approval of alcohol use (injunctive norms) predicted their alcohol use. Results Both use and approval perceptions by upperclassmen, same-team, and most influential friends significantly predicted alcohol use. By contrast, only perceived use by first-year, non-team, and less influential friends significantly predicted alcohol use. Conclusions Athletics departments’ alcohol policies and prevention programming for first-year student-athletes should address the potential influence of different types of friends on alcohol use.

2011-12-05

In contrast to Internet search engines, social media on the Internet such as Facebook, Twitter, etc. reach a large number of people, who are ready to help answering questions. This type of information aggregation has been dubbed "crowdsourcing" i.e. outsourcing a task to a large group of people or community (a crowd) through an open call. Our aim was to explore whether laypersons via Facebook friends could crowd source their way to a medical diagnosis based on a brief medical history, posted as a status update on Facebook. The participants posted a brief case story on their Facebook profile and asked their "Facebook friends" to come up with possible diagnoses. The correct diagnosis was suggested in five of the six case stories, and the correct diagnosis was made after a median of ten minutes. The quality of the responses varied from relevant differential diagnoses to very silly diagnostic suggestions. Based on this study, we believe that laypersons can use his or her "Facebook friends" to identify the need to see a doctor for their symptoms rather than relying on them to give them a specific diagnosis for their symptoms.

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.

Towards a Research Agenda for Cyber Friendly Fire

2009-11-18

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.

2013-10-01

We examined the potential moderating role of Block's personality types (i.e., overcontrollers, undercontrollers, and resilients) on the longitudinal associations between adolescents' and their best friends' delinquency. Across three annual waves, 497 Dutch adolescents (283 boys, M(Age) = 13 years at Wave 1) and their best friends reported on their delinquent behaviors. Adolescents' three personality types were obtained by latent class growth analysis on their annual reports on Big Five personality. A three-group cross-lagged panel analysis was performed on three waves of data. Delinquency of overcontrollers was predicted by their best friends' delinquency, whereas delinquency of undercontrollers and resilients was not. Delinquency of undercontrollers and resilients predicted their best friends' delinquency, but overcontrollers' delinquency did not. These findings suggest that personality may play an important role in adolescents' susceptibility to the influence of friends' delinquency, as well as in youths' ability to influence friends through their own delinquency. © 2013 Wiley Periodicals, Inc.

Eco-friendly or green dentistry can be a reality by effectively designing dental clinics and using more eco-friendly materials in the clinical practice. To determine the awareness of eco-friendly dentistry among dental faculty and students in preparation for future implementation. Assessment of knowledge regarding eco-friendly dentistry was done using an 18 item self-administered questionnaire among 160 participants. After baseline data collection, the intervention was done by educating participants with a power point presentation. The post-intervention data was then collected for analysis. Statistical analysis was done using Wilcoxon's signed rank test and one-way ANOVA. The educational intervention increased the knowledge about eco-friendly dentistry confirming the importance of continuing education. There was a statistically significant gain in knowledge among the participants after the presentation. The gain was highest for department of Preventive Dental Sciences (PDS) followed by Substitute Dental Sciences (SDS), No specialty, Maxillofacial Dental Sciences (MDS), and Restorative Dental Sciences (RDS) respectively. (F=5.5091, p<0.05). Lack of knowledge of green dentistry amongst the dental fraternity is highly prevailing. The same can be substantiated with effective training in the respective fields if channelized through the curriculum in an educational set-up.

The aim of this study was to verify the association between different types and sources of social support and physical activity among adolescents from Curitiba, Paraná State, Brazil. A school-based survey was conducted with a representative sample of adolescents from public schools (n = 1,469). Multiple regression models were used to test the association between weekly frequency and sources of social support from family and friends and weekly frequency of physical activity. Among boys, frequent company of family (PR: 2.88; 95%CI: 2.00-4.13) and friends (PR: 5.46; 95%CI: 2.33-12.78) and positive reinforcement from friends (PR: 1.81; 95%CI: 1.18-2.77) were positively associated with physical activity. Sporadic invitation by the family was negatively associated with physical activity (PR: 0.66; 95%CI: 0.46-1.14). For girls, frequent company of family (PR: 3.39; 95%CI: 1.49-7.69) and friends (PR: 4.06; 95%CI: 2.22-7.45) increased the likelihood of physical activity. Company of friends was the most important type of social support for physical activity among these adolescents.

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.

 High-profile sportspeople are posited as role models for others. We examine whether university sportspeople and non-sportspeople's perceptions of high-profile sportspeople's (sports stars) and friends perceived drinking behaviours are related to their own drinking behaviours. Further, we examine the importance of drinking with competitors after sports events.  A convenience sample of 1028 participants (58% females, n=652 sportspeople) from two Australian universities were approached at sporting and university venues. Participants completed a survey booklet containing demographic questions, the Alcohol Use Disorders Identification Test (AUDIT, alcohol measure), perceived drinking of high-profile sportspeople and friends (social norms), and for sportspeople only, items assessing the importance of drinking with competitors. Bivariate and multivariate analyses were used to assess relationships.  Both sporting and non-sporting participants perceived high-profile sportspeople to drink less than themselves and their friends. Small significant bivariate relationships were found between high-profile sportspeople's perceived drinking and self-reported drinking for sportspeople (r=0.20, P competitors after sports and games accounted for an additional 6.1% of the unique variance in AUDIT-scores (P<0.0005).  Sports stars are touted as negative role models when it comes to drinking. Contrary to expectations high-profile sportspeople were not perceived to be heavy drinkers and their perceived drinking was not predictive of others drinking. Friends' and normative drinking practices were predictors of drinking.[O'Brien KS, Kolt GS, Webber A, Hunter JA.

Friends' knowledge of youth internalizing and externalizing adjustment: accuracy, bias, and the influences of gender, grade, positive friendship quality, and self-disclosure.

Science.gov (United States)

Swenson, Lance P; Rose, Amanda J

2009-08-01

Some evidence suggests that close friends may be knowledgeable of youth's psychological adjustment. However, friends are understudied as reporters of adjustment. The current study examines associations between self- and friend-reports of internalizing and externalizing adjustment in a community sample of fifth-, eighth-, and eleventh-grade youth. The study extends prior work by considering the degree to which friends' reports of youth adjustment are accurate (i.e., predicted by youths' actual adjustment) versus biased (i.e., predicted by the friend reporters' own adjustment). Findings indicated stronger bias effects than accuracy effects, but the accuracy effects were significant for both internalizing and externalizing adjustment. Additionally, friends who perceived their relationships as high in positive quality, friends in relationships high in disclosure, and girls perceived youths' internalizing symptoms most accurately. Knowledge of externalizing adjustment was not influenced by gender, grade, relationship quality, or self-disclosure. Findings suggest that friends could play an important role in prevention efforts.

Using budget-friendly methods to analyze sport specific movements

Science.gov (United States)

Jackson, Lindsay; Williams, Sarah; Ferrara, Davon

2015-03-01

When breaking down the physics behind sport specific movements, athletes, usually professional, are often assessed in multimillion-dollar laboratories and facilities. Budget-friendly methods, such as video analysis using low-cost cameras, iPhone sensors, or inexpensive force sensors can make this process more accessible to amateur athletes, which in-turn can give insight into injury mechanisms. Here we present a comparison of two methods of determining the forces experienced by a cheerleader during co-education stunting and soccer goalies while side-diving. For the cheerleader, accelerometer measurements were taken by an iPhone 5 and compared to video analysis. The measurements done on the soccer players were taken using FlexiForce force sensors and again compared to video analysis. While these budget-friendly methods could use some refining, they show promise for producing usable measurements for possibly increasing our understanding of injury in amateur players. Furthermore, low-cost physics experiments with sports can foster an active learning environment for students with minimum physics and mathematical background.

Friend networking sites and their relationship to adolescents' well-being and social self-esteem.

Science.gov (United States)

Valkenburg, Patti M; Peter, Jochen; Schouten, Alexander P

2006-10-01

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.

A child-centred exploration of the relevance of family and friends to theory of mind development.

Science.gov (United States)

Wright, Barlow C; Mahfoud, Janina

2012-02-01

Theory of Mind (ToM) is said to develop at around 4 years old. But some studies suggest it develops considerably earlier than this, with others suggesting it develops much later. Although several recent studies have found that social factors (like gender, family size, number of siblings, and number of friends) can impact on ToM, other studies contradict those findings. We wondered whether addressing several procedural issues and ensuring the task concerns real protagonists in real time, would bear on the above issues. Here, 114 children of 3-6 years completed four ToM tasks incorporating controls from experimental psychology, including randomly varying the order of ToM and non-ToM questions across participants. Now, children passed ToM tasks from around 5 years old, rather than 4 years or earlier. Girls did not develop ToM any earlier than boys. There was clear correlational evidence for the older-sibling effect and effects of friends but no reliable effects of nuclear or extended family. However, when these factors were set in the context of one another, the sibling effect was driven by a negative influence from younger siblings (as opposed to older siblings) and the friends effect was driven by friends at school (as opposed to friends at home). Finally, "friends" was a stronger predictor than siblings but memory (a cognitive factor) and age (a maturational factor) were the strongest predictors of all. © 2011 The Authors.

Burk, William J.; Stoltz, Sabine E. M. J.; van den Berg, Yvonne H. M.; Cillessen, Antonius H. N.

2018-01-01

Research on gaming effects has focused on adolescence, a developmental period in which peer relationships become increasingly salient. However, the impact of peers on the effects of violent gaming on adolescents has been understudied. This study examined whether adolescents’ exposure to violent video games predicted their own and their friend's aggression one year later. Among 705 gaming adolescents, 141 dyads were identified based on reciprocated best friend nominations (73.8% male, Mage = 13.98). Actor‐Partner Interdependence Models indicated that adolescent males’ (but not females’) exposure to violent games positively predicted the aggression of their best friend 1 year later. This effect appeared regardless of whether the friends played video games together or not. The study illustrates the importance of peers in the association between violent gaming and aggression.

An argument is developed through a narrative review of (i) the proven efficacy of family interventions, and (by comparison) a relative absence of friend-based interventions; (ii) the particular primacy of friendships and dating for young people, and typical effects of exclusion; and (iii) reduced friendship networks and dating experiences in psychosis, in pre-, during and post-psychosis phases, also links between exclusion and psychosis. We put forward a model of how poor friendships can potentially be a causal and/or maintenance factor for psychotic symptoms. Given this model, our thesis is that interventions aiming to maintain social networks can be hugely beneficial clinically for young people with psychosis. We give a case study to show how such an intervention can work. We call for 'friends interventions' for young people with psychosis to be developed, where professionals directly work with a young person's authentic social group to support key friendships and maintain social continuity. An agenda for future research is presented that will develop and test theoretically driven interventions. © 2014 Wiley Publishing Asia Pty Ltd.

A Hero in the Friendly Arctic: Deconstructing Vilhjalmur Stefansson's Rhetorical Maneuver

Full Text Available The article deals with Arctic explorer and anthropologist Vilhjalmur Stefansson's self-presentation in the expedition account The Friendly Arctic: The Story of Five Years in Polar Regions (1921, which tells the story of his travels and trials in the Canadian High Arctic in the years between 1913-1918. The account has been considered a key text to Stefansson's Arctic career, and provides a textbook example of his characteristic theory of living off the country in the so-called Eskimo way. Against the background of Stefansson's debated position as Arctic expert and visionary, I ask if it is possible to read the kind of criticism with which Stefansson frequently was met as rooted in some of the narrative aspects of his account. The narrative persona or implied author is a central element in the literature of exploration, as several literary scholars have pointed out. My reading is centred around the implied author of The Friendly Arctic, which I argue must be read in light of the sometimes conflicting roles given to Stefansson as protagonist and narrator in his own story. Close-readings of passages from the account raise the dilemma of how it is possible to present oneself as a hero in an essentially friendly Arctic.

Background: 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. Methods: 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. Results: 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. Conclusions: 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.

Age-friendly initiatives are increasingly promoted as a policy solution to healthy aging, The primary objective of this article was to examine older adults' and key stakeholders' perceptions of the factors that either help or hinder a community from becoming age-friendly in the context of rural Manitoba, a Canadian prairie province. Twenty-four older adults and 17 key informants completed a qualitative interview. The findings show that contextual factors including size, location, demographic composition, ability to secure investments, and leadership influence rural communities' ability to become age-friendly. Government must consider the challenges these communities face in becoming more age-friendly and develop strategies to support communities. © The Author(s) 2013.

Regular physical activity, even at modest intensities, is associated with many health benefits. Most Americans, however, do not engage in the recommended levels. As practitioners seek ways to increase population rates of physical activity, interventions and advocacy efforts are being targeted to the community level. Yet, advocates, community leaders, and researchers lack the tools needed to assess local barriers to and opportunities for more active, healthy lifestyles. Investigators used a systematic review process to identify key indicators of activity-friendly communities that can assess and improve opportunities for regular physical activity. Investigators conducted a comprehensive literature review of both peer-reviewed literature and fugitive information (e.g., reports and websites) to generate an initial list of indicators for review (n=230). The review included a three-tiered, modified Delphi consensus-development process that incorporated input of international, national, state, and local researchers and practitioners from academic institutions, federal and state government agencies, nonprofit organizations, and funding agencies in public health, transportation, urban planning, parks and recreation, and public policy. Ten promising indicators of activity-friendly communities were identified: land use environment, access to exercise facilities, transportation environment, aesthetics, travel patterns, social environment, land use economics, transportation economics, institutional and organizational policies, and promotion. Collaborative, multidisciplinary approaches are underway to test, refine, and expand this initial list of indicators and to develop measures that communities, community leaders, and policymakers can use to design more activity-friendly community environments.

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.

Environmentally friendly supercapacitors are fabricated using commercial grade aluminum coated paper as a substrate and symmetrical activated carbon electrodes as large area electrodes. Different choline chloride-based eutectic solvents are used as electrolyte. These are inexpensive, environmentally friendly and have a larger operating window compared to that of water electrolytes. As the entire device is printed and the materials used are inexpensive, both small- and large-area power sources can be fabricated to be used in cheap, disposable and recyclable devices. Supercapacitors with different eutectic solvents are measured using cyclic charge-discharge and impedance spectroscopy measurements and compared to one widely used and one "green" imidazolium ionic liquid; EMIM:TFSI and EcoEng 212™, respectively. A mixture of ethylene glycol and choline chloride, Glyceline™, show the highest capacitance and power densities of the electrolytes being tested, including the imidazolium alternatives.

Smurf1 Inhibits Osteoblast Differentiation, Bone Formation, and Glucose Homeostasis through Serine 148

Directory of Open Access Journals (Sweden)

2016-04-01

Full Text Available The E3 ubiquitin ligase Smurf1 targets the master regulator of osteoblast differentiation, Runx2, for degradation, yet the function of Smurf1, if any, during osteoblast differentiation in vivo is ill defined. Here, we show that Smurf1 prevents osteoblast differentiation by decreasing Runx2 accumulation in osteoblasts. Remarkably, mice harboring a substitution mutation at serine 148 (S148 in Smurf1 that prevents its phosphorylation by AMPK (Smurf1ki/ki display a premature osteoblast differentiation phenotype that is equally severe as that of Smurf1−/− mice, as well as a high bone mass, and are also hyperinsulinemic and hypoglycemic. Consistent with the fact that Smurf1 targets the insulin receptor for degradation, there is, in Smurf1ki/ki mice, an increase in insulin signaling in osteoblasts that triggers a rise in the circulating levels of osteocalcin, a hormone that favors insulin secretion. These results identify Smurf1 as a determinant of osteoblast differentiation during the development of bone formation and glucose homeostasis post-natally and demonstrate the necessity of S148 for these functions.

Man's best friend: How humans can develop Dirofilaria immitis infections

Directory of Open Access Journals (Sweden)

Devin Malik

2016-01-01

Full Text Available Canine heartworm, Dirofilaria immitis, is a nematode parasite that infects dogs by way of mosquito bite. Rarely, humans play accidental hosts to this parasite and are not a suitable environment for the nematode to live. As the parasite dies in the pulmonary vessels it embolizes the vessels causing infarction and eventual nodule formation in the lungs. In the right clinical context, a nodule can be considered malignant prompting invasive tissue sampling. We describe a case of a 48-year-old man who was found to have multiple asymptomatic scattered pulmonary nodules during imaging workup for an insulinoma. Fine needle biopsy of the largest nodule revealed a necrotic granuloma, lab testing and culture ruled out fungal and bacterial causes. Clinically, this picture was consistent with D. immitis infection.

Research on gaming effects has focused on adolescence, a developmental period in which peer relationships become increasingly salient. However, the impact of peers on the effects of violent gaming on adolescents has been understudied. This study examined whether adolescents' exposure to violent video games predicted their own and their friend's aggression one year later. Among 705 gaming adolescents, 141 dyads were identified based on reciprocated best friend nominations (73.8% male, M age  = 13.98). Actor-Partner Interdependence Models indicated that adolescent males' (but not females') exposure to violent games positively predicted the aggression of their best friend 1 year later. This effect appeared regardless of whether the friends played video games together or not. The study illustrates the importance of peers in the association between violent gaming and aggression. © 2018 The Authors. Aggressive Behavior Published by Wiley Periodicals, Inc.

Hanging Out with Which Friends? Friendship-Level Predictors of Unstructured and Unsupervised Socializing in Adolescence

Science.gov (United States)

Siennick, Sonja E.; Osgood, D. Wayne

2012-01-01

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.

This study investigates the independent and combined effects of smoking of parents and best friend on smoking and the intention to initiate or quit smoking in adolescents. In this school-based survey, 6,553 Hong Kong students aged 13-18 reported their demographic characteristics, smoking status of themselves, parents, and best friend; and intention to smoke (initiation among never-smokers and reinitiation among ex-smokers) or quit smoking among current smokers. Logistic regression yielded adjusted odds ratios (AORs) of student smoking (current/ever) and intention to smoke or quit smoking for parental (paternal/maternal/both parents vs. none) and best friend (yes vs. no) smoking. Parental smoking and having a smoking best friend were associated with adolescent current smoking, ever smoking, and intention to initiate smoking. Having a smoking best friend was also associated with reinitiating and quitting smoking. The AORs (95% CI) of current smoking for having a smoking best friend, in addition to smoking father, mother, or both were 19.14 (14.36-25.51), 20.38 (12.42-33.43), and 24.18 (15.89-36.77). The respective AORs of ever smoking were 8.30 (6.74-10.22), 8.92 (5.63-14.12), and 11.99 (8.05-17.87). Parental smoking and best friend smoking have independent effects on adolescent smoking behaviors. Their combined effects on current and ever smoking were particularly large. Smoking prevention programs should pay special attention to adolescents with both best friend and parents who smoke.

Towards eco-friendly crop protection: natural deep eutectic solvents and defensive secondary metabolites.

With mounting concerns over health and environmental effects of pesticides, the search for environmentally acceptable substitutes has amplified. Plant secondary metabolites appear in the horizon as an attractive solution for green crop protection. This paper reviews the need for changes in the techniques and compounds that, until recently, have been the mainstay for dealing with pest insects. Here we describe and discuss main strategies for selecting plant-derived metabolites as candidates for sustainable agriculture. The second part surveys ten important insecticidal compounds, with special emphasis on those involved in human health. Many of these insecticidal metabolites, however, are crystalline solids with limited solubility which might potentially hamper commercial formulation. As such, we introduce the concept of natural deep eutectic solvents for enhancing solubility and stability of such compounds. The concept, principles and examples of green pest control discussed here offer a new suite of environmental-friendly tools designed to promote and adopt sustainable agriculture.

Li, Xuran; Wang, Qiu; Dai, Hong-Ning; Wang, Hao

2018-06-14

Eavesdropping attack is one of the most serious threats in industrial crowdsensing networks. In this paper, we propose a novel anti-eavesdropping scheme by introducing friendly jammers to an industrial crowdsensing network. In particular, we establish a theoretical framework considering both the probability of eavesdropping attacks and the probability of successful transmission to evaluate the effectiveness of our scheme. Our framework takes into account various channel conditions such as path loss, Rayleigh fading, and the antenna type of friendly jammers. Our results show that using jammers in industrial crowdsensing networks can effectively reduce the eavesdropping risk while having no significant influence on legitimate communications.

Time spent with friends in adolescence relates to less neural sensitivity to later peer rejection.

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.

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.

Advanced Environment Friendly Nanotechnologies

Figovsky, O.; Beilin, D.; Blank, N.

The economic, security, military and environmental implications of molecular manufacturing are extreme. Unfortunately, conflicting definitions of nanotechnology and blurry distinctions between significantly different fields have complicated the effort to understand those differences and to develop sensible, effective policy for each. The risks of today's nanoscale technologies cannot be treated the same as the risks of longer-term molecular manufacturing. It is a mistake to put them together in one basket for policy consideration — each is important to address, but they offer different problems and will require far different solutions. As used today, the term nanotechnology usually refers to a broad collection of mostly disconnected fields. Essentially, anything sufficiently small and interesting can be called nanotechnology. Much of it is harmless. For the rest, much of the harm is of familiar and limited quality. Molecular manufacturing, by contrast, will bring unfamiliar risks and new classes of problems. The advanced environment friendly nanotechnologies elaborated by Israel Company Polymate Ltd. — International Research Center are illustrated.

Friends are important in childhood and adolescence, especially to bullied children. Technology mediated communication (TMC) could be used both to develop and maintain friendship. The present study examined (1) trends in the use of TMC with friends between 2001 and 2010; (2) possible differences between bullied and not bullied children and (3) differences between children with few close friends and children with several close friends. Data were obtained from three waves of the serial cross-sectional Health Behaviour in School-Aged Children survey conducted in Denmark, Finland, Iceland and Sweden during 2001/2002, 2005/2006 and 2009/2010. The total sample consisted of 65 953 children aged 11, 13 and 15. Two trends were observed. The first trend showed an increased use of TMC in all countries. Children that were not bullied and/or had several close friends had increased their use of TMC with friends from 2001 to 2010. The second trend was applicable only for bullied children with few close friends; they had not as other children increased their use of TMC and thus remained at the same levels as in 2001/2002. Bullied children with few close friends were excluded from communication forums that usually allow children to maintain and develop friendships. This is a concern because friends are important during childhood and adolescence, especially for bullied children. © 2016 John Wiley & Sons Ltd.

“Dude, You’re Such a Slut!” Barriers and Facilitators of Sexual Communication Among Young Gay Men and Their Best Friends

Science.gov (United States)

McDavitt, Bryce; Mutchler, Matt G.

2014-01-01

Conversations with friends are a crucial source of information about sexuality for young gay men, and a key way that sexual health norms are shared during emerging adulthood. However, friends can only provide this support if they are able to talk openly about sexuality. We explored this issue through qualitative interviews with an ethnically diverse sample of young gay men and their best friends. Using theories of sexual scripts, stigma, and emerging adulthood, we examined how conversations about sex could be obstructed or facilitated by several key factors, including judgmentalism, comfort/discomfort, and receptivity. Gay male friends sometimes spoke about unprotected sex in judgmental ways (e.g., calling a friend “slut” or “whore” for having sex without condoms). In some cases, this language could be used playfully, while in others it had the effect of shaming a friend and obstructing further communication about sexual risk. Female friends were rarely openly judgmental, but often felt uncomfortable talking about gay male sexuality, which could render this topic taboo. Sexual communication was facilitated most effectively when friends encouraged it through humor or supportive questioning. Drawing on these findings, we show how judgmentalism and discomfort may generate sexual scripts with contradictory norms, and potentially obstruct support from friends around sexual exploration during a period of life when it may be most developmentally important.

This integrative review aimed to identify and synthesize information on the barriers, facilitators, and recommendations related to the BFI from the international, peer-reviewed literature. Thirteen databases were searched using the keywords Baby Friendly, Baby-Friendly Hospital Initiative, BFI, BFHI, Ten Steps, implementation, adoption, barriers, facilitators, and their combinations. A total of 45 English-language articles from 16 different countries met the inclusion criteria for the review. Data analysis was guided by Cooper's five stages of integrative research review. Using a multiple intervention program framework, findings were categorized into sociopolitical, organizational-level, and individual-level barriers and facilitators to implementing the BFI, as well as intra-, inter-, and extraorganizational recommendations for strengthening BFI implementation. A wide variety of obstacles and potential solutions to BFI implementation were identified. Findings suggest some priority issues to address when pursuing Baby-Friendly designation, including the endorsements of both local administrators and governmental policy makers, effective leadership of the practice change process, health care worker training, the marketing influence of formula companies, and integrating hospital and community health services. Framing the BFI as a complex, multilevel, evidence-based change process and using context-focused research implementation models to guide BFI implementation efforts may help identify effective strategies for promoting wider adoption of the BFI in health services.

Lesbian, gay, bisexual, and transgender (LGBT) older adult caregivers may encounter obstacles in obtaining health and aging services due to discrimination in service and legal systems. The caregiving relationships in LGBT communities also differ from the general population in that friends are providing a large portion of informal care. This article examines how the relational context of caregiving relates to caregiving demands and resources, which in turn, influence perceived stress and depressive symptomatology among older LGBT caregivers. Using data from the National Health, Aging, and Sexuality Study: Caring and Aging with Pride, this study examines 451 participants who are providing caregiving to partners and friends. Structural equation modeling was applied to estimate the associations among the caregiver-care recipient relationship and caregiving demands, resources, perceived stress, and depressive symptomatology. On average, as compared with those caring for partners, those who provided care to friends reported experiencing lower levels of caregiving demands and lower levels of social support. The lower caregiving demands correlated positively with both lower perceived stress and less severe depressive symptomatology; however, the lower levels of social support were related to higher perceived stress and higher depressive symptomatology. Caregiving provided by friends, which has long been under recognized, plays an important role in the LGBT community. Because lower levels of caregiving demands are offset by less social support, LGBT friend-caregivers experience similar levels of perceived stress and depressive symptomatology to those providing care to spouses and partners. Policy and service reforms are needed to better acknowledge the continuum of informal caregiving relationships.

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

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.

In-vehicle human factors for integrated multi-function systems: Making ITS user-friendly

As more and more Intelligent Transportation System in-vehicle equipment enters the general consumer market, the authors are about to find out how different design engineers are from ordinary drivers. Driver information systems are being developed and installed in vehicles at an ever-increasing rate. These systems provide information on diverse topics of concern and convenience to the driver, such as routing and navigation, emergency and collision warnings, and a variety of motorists services, or yellow pages functions. Most of these systems are being developed and installed in isolation from each other, with separate means of gathering the information and of displaying it to the driver. The current lack of coordination among on-board systems threatens to create a situation in which different messages on separate displays will be competing with each other for the drivers attention. Urgent messages may go unnoticed, and the number of messages may distract the driver from the most critical task of controlling the vehicle. Thus, without good human factors design and engineering for integrating multiple systems in the vehicle, consumers may find ITS systems confusing and frustrating to use. The current state of the art in human factors research and design for in-vehicle systems has a number of fundamental gaps. Some of these gaps were identified during the Intelligent Vehicle Initiative Human Factors Technology Workshop, sponsored by the US Department of Transportation, in Troy, Michigan, December 10--11, 1997. One task for workshop participants was to identify needed research areas or topics relating to in-vehicle human factors. The top ten unmet research needs from this workshop are presented. Many of these gaps in human factors research knowledge indicate the need for standardization in the functioning of interfaces for safety-related devices such as collision avoidance systems (CAS) and adaptive cruise controls (ACC). Such standards and guidelines will serve to make

To assess the influence of smoking and tombak (local smokeless tobacco) dipping by parents, teachers and friends on cigarette smoking and tombak dipping by school-going Sudanese adolescents. This was a school-based cross-sectional survey was conducted in 2005-2006. Logistic regression was used for the analysis. A total of 4277 Sudanese school-going adolescents (aged 11-17 years) from 23 schools who completed an anonymous self-administered questionnaire on the use of tobacco products. Main outcome measures were self-reported tobacco use during the previous month defined current tobacco use. Ever smoking, tombak dipping and other tobacco products were also considered as outcomes. After adjusting for sex, age and school grade, adolescents' smoking habits were strongly associated with the habit in their parents and friends and, more weakly, with tombak dipping by teachers. When adjusted for each other, the association with smoking in friends was unaffected and remained significant (prevalence OR (POR) of having ever smoked was 1.94, 95% CI 1.64 to 2.29; OR of being current smoker was 3.77, 95% CI 2.80 to 5.07). Tobacco smoking in friends was positively associated with adolescents ever tombak dipping (POR 1.81, 95% CI 1.41 to 2.33) and current dipping (OR 3.33, 95% CI 2.20 to 5.05). The association with parental habits was reduced but still significantly elevated. Tombak dipping by teachers was only associated with adolescents ever tobacco smoking. Tobacco use by parents, teachers and friends was associated with adolescents' tobacco habits. The influence of friends was the strongest. In developing programmes against adolescents' tobacco habits, there is need to target the influence of these 'significant others'. Sudan needs to develop and implement comprehensive anti-smoking and anti-tombak dipping legislation to reduce the growing prevalence of such habits.

Durations of breastfeeding activity in the United States fall short of established recommendations by leading public health institutions. In response to this problem, this study sought to develop environmentally friendly messages to promote continued breastfeeding for moms already breastfeeding in order to help them reach recommended breastfeeding durations. Messages were successfully cultivated to encourage moms already breastfeeding to meet recommended breastfeeding durations. In addition, this study cultivated strategies by which to use environmentally friendly messages to urge mothers who still need to decide whether to breastfeed or formula feed to breastfeed, although this was not the purpose of the research. Avenues for future communication-based breastfeeding research were also elucidated. The Elaboration Likelihood Model serves as useful theory to assess the role of environmentally friendly messages in the promotion of continued breastfeeding.

The tendency to keep secrets in adolescents has been studied in particular in their relationships with their parents and associated with psychosocial disadvantages. The current study focused on peer relationships and investigated the effects of friendship quality, loneliness in a multidimensional perspective, and self-esteem on secrecy from friends. Italian adolescents (N = 457; 47% male; 100% white) aged between 13 and 19 years (M = 16.11; SD = 1.53) reported their secrecy from friends, peer and parent-related loneliness, aversion and affinity for aloneness, their self-esteem and the quality of their relationships with their friends. The results showed that peer-related loneliness, affinity for aloneness and self-esteem in particular affect keeping secrets from friends, independent of the participant's gender. Moreover, peer-related loneliness and affinity for aloneness mediated the relationship between self-esteem and secrecy. The data were discussed in the light of adolescence developmental tasks.

Prinstein, Mitchell J; Wang, Shirley S

2005-06-01

Adolescents' perceptions of their friends' behavior strongly predict adolescents' own behavior, however, these perceptions often are erroneous. This study examined correlates of discrepancies between adolescents' perceptions and friends' reports of behavior. A total of 120 11th-grade adolescents provided data regarding their engagement in deviant and health risk behaviors, as well as their perceptions of the behavior of their best friend, as identified through sociometric assessment. Data from friends' own report were used to calculate discrepancy measures of adolescents' overestimations and estimation errors (absolute value of discrepancies) of friends' behavior. Adolescents also completed a measure of friendship quality, and a sociometric assessment yielding measures of peer acceptance/rejection and aggression. Findings revealed that adolescents' peer rejection and aggression were associated with greater overestimations of friends' behavior. This effect was partially mediated by adolescents' own behavior, consistent with a false consensus effect. Low levels of positive friendship quality were significantly associated with estimation errors, but not overestimations specifically.

The DMT has developed an industrial briquette consisting of about 87% hardcoal, 7% molasses pulp and 6% hydration limestone which meets the requirements of the clean air authority as an environmentally friendly fuel for travelling grate boilers. In extensive tests in a 4.4 MW travelling grate boiler these briquettes with molasses and limestone additives proved to be particularly effective in terms of reducing sulphur dioxide emission in the flue gas. They exhibited good ignition and combustion behaviour as well as a considerable reduction in nitrogen oxide emission. In a large-scale test with 1000 t of briquettes in a 46.5 MW travelling grate furnace it proved possible to confirm the good combustion behaviour and the reduced emission of sulphur oxide and nitrogen oxide in the flue gas.

Friend tumor cells (FTC) have been studied by growing them in lethally irradiated syngeneic mice. After establishing the FTC dilution factor (delta), extinction factor (Q), and the optimal time for colony counts, the FTC kinetic was analyzed by the recovery curve method. It was found that FTC growth is different from that experienced by normal or leukemic Friend stem cells when tested by the same in vivo assay. The most interesting differences were the high metastatic activity, the lack of differentiation, the deterministic growth, and the independence from the spleen microenvironment experienced by the FTC, in contrast with the normal and leukemic stem cells. In addition, the estimate of the critical size the FTC colony has to reach before releasing the first metastatic cells is presented. (U.S.)

Despite increasing research on indiscriminate friendliness in children, almost no research exists on social-cognitive deficits that are supposed to underlie indiscriminately friendly behavior. In this study, we compared indiscriminately friendly children with controls regarding their perceptions of self, reliability trust in significant others, and perceptions of the teacher-child relationship. Children's perceptions were compared in two samples: a sample of 33 likely cases for disinhibited reactive attachment disorder (RAD) from special education for children with emotional and behavioral disorders (75.76% boys, Mage=8.52, 96.9% Caucasian, 33.3% and 45.5% of their mothers completed primary or secondary education, respectively) was matched on sex, age, and socio-economic status with a sample of 33 controls from general education. Children participated individually in several interviews assessing global and social self-concept, reliability trust in significant others, teacher-child relationship perceptions, and vocabulary. Parents and teachers completed a screening questionnaire for RAD and the Strengths and Difficulties Questionnaire. Likely disinhibited RAD-cases showed more indiscriminate friendliness and more problem behavior in general according to their parents and teachers than controls. Furthermore, likely RAD-cases reported a more positive global self-concept, more reliability trust in significant others, and more dependency in the teacher-child relationship than controls. The results are in line with clinical observations of indiscriminately friendly children and findings in clinical samples of maltreated or attachment disrupted children but contrast hypotheses from developmental attachment research. Further research is needed to explain the more positive perceptions of indiscriminately friendly children. Copyright © 2014 Elsevier Ltd. All rights reserved.

Country roads, take me home… to my friends: How intelligence, population density, and friendship affect modern happiness.

2016-11-01

We propose the savanna theory of happiness, which suggests that it is not only the current consequences of a given situation but also its ancestral consequences that affect individuals' life satisfaction and explains why such influences of ancestral consequences might interact with intelligence. We choose two varied factors that characterize basic differences between ancestral and modern life - population density and frequency of socialization with friends - as empirical test cases. As predicted by the theory, population density is negatively, and frequency of socialization with friends is positively, associated with life satisfaction. More importantly, the main associations of life satisfaction with population density and socialization with friends significantly interact with intelligence, and, in the latter case, the main association is reversed among the extremely intelligent. More intelligent individuals experience lower life satisfaction with more frequent socialization with friends. This study highlights the utility of incorporating evolutionary perspectives in the study of subjective well-being. © 2016 The British Psychological Society.
