Oxytocin increases eye contact during a real-time, naturalistic social interaction in males with and without autism

Autism spectrum conditions (autism) affect ~1% of the population and are characterized by deficits in social communication. Oxytocin has been widely reported to affect social-communicative function and its neural underpinnings. Here we report the first evidence that intranasal oxytocin administration improves a core problem that individuals with autism have in using eye contact appropriately in real-world social settings. A randomized double-blind, placebo-controlled, within-subjects design is used to examine how intranasal administration of 24 IU of oxytocin affects gaze behavior for 32 adult males with autism and 34 controls in a real-time interaction with a researcher. This interactive paradigm bypasses many of the limitations encountered with conventional static or computer-based stimuli. Eye movements are recorded using eye tracking, providing an objective measurement of looking patterns. The measure is shown to be sensitive to the reduced eye contact commonly reported in autism, with the autism group spending less time looking to the eye region of the face than controls. Oxytocin administration selectively enhanced gaze to the eyes in both the autism and control groups (transformed mean eye-fixation difference per second=0.082; 95% CI:0.025–0.14, P=0.006). Within the autism group, oxytocin has the most effect on fixation duration in individuals with impaired levels of eye contact at baseline (Cohen’s d=0.86). These findings demonstrate that the potential benefits of oxytocin in autism extend to a real-time interaction, providing evidence of a therapeutic effect in a key aspect of social communication.

Analysis and modeling of Diacamma workers’ behavior

It is well-known that social insects such as ants show interesting collective behaviors. How do they organize such behaviors? To expand understanding of collective behaviors of social insects, we focused on ants, Diacamma, and analyzed the behavior of a few individuals. In an experimental set-up, ants are placed in hemisphere without a nest and food and the trajectory of ants is recorded. From this bottom-up approach, we found following characteristics: 1. Activity of individuals increases and decreases periodically. 2. Spontaneous meeting process is observed between two ants and meeting spot of two ants is localized in the experimental field.

Targeting medication non-adherence behavior in selected autoimmune diseases: a systematic approach to digital health program development

Background 29 autoimmune diseases, including Rheumatoid Arthritis, gout, Crohn’s Disease, and Systematic Lupus Erythematosus affect 7.6-9.4% of the population. While effective therapy is available, many patients do not follow treatment or use medications as directed. Digital health and Web 2.0 interventions have demonstrated much promise in increasing medication and treatment adherence, but to date many Internet tools have proven disappointing. In fact, most digital interventions continue to suffer from high attrition in patient populations, are burdensome for healthcare professionals, and have relatively short life spans. Objective Digital health tools have traditionally centered on the transformation of existing interventions (such as diaries, trackers, stage-based or cognitive behavioral therapy programs, coupons, or symptom checklists) to electronic format. Advanced digital interventions have also incorporated attributes of Web 2.0 such as social networking, text messaging, and the use of video. Despite these efforts, there has not been little measurable impact in non-adherence for illnesses that require medical interventions, and research must look to other strategies or development methodologies. As a first step in investigating the feasibility of developing such a tool, the objective of the current study is to systematically rate factors of non-adherence that have been reported in past research studies. Methods Grounded Theory, recognized as a rigorous method that facilitates the emergence of new themes through systematic analysis, data collection and coding, was used to analyze quantitative, qualitative and mixed method studies addressing the following autoimmune diseases: Rheumatoid Arthritis, gout, Crohn’s Disease, Systematic Lupus Erythematosus, and inflammatory bowel disease. Studies were only included if they contained primary data addressing the relationship with non-adherence. Results Out of the 27 studies, four non-modifiable and 11 modifiable risk factors were discovered. Over one third of articles identified the following risk factors as common contributors to medication non-adherence (percent of studies reporting): patients not understanding treatment (44%), side effects (41%), age (37%), dose regimen (33%), and perceived medication ineffectiveness (33%). An unanticipated finding that emerged was the need for risk stratification tools (81%) with patient-centric approaches (67%). Conclusions This study systematically identifies and categorizes medication non-adherence risk factors in select autoimmune diseases. Findings indicate that patients understanding of their disease and the role of medication are paramount. An unexpected finding was that the majority of research articles called for the creation of tailored, patient-centric interventions that dispel personal misconceptions about disease, pharmacotherapy, and how the body responds to treatment. To our knowledge, these interventions do not yet exist in digital format. Rather than adopting a systems level approach, digital health programs should focus on cohorts with heterogeneous needs, and develop tailored interventions based on individual non-adherence patterns.

Self-concept clarity, social support, and Compulsive Internet Use: a study of the USA and the UAE

Compulsive Internet Use (CIU) has been mostly studied among adolescents, yet some studies reveal that this can be a problem for the adult population, too. The lack of agreement on diagnostic tools and cut-off points results in markedly different prevalence figures. Building on Charlton’s (2002) distinction between core CIU and positive engagement dimensions, the first objective was to confirm that prevalence figures including the core dimensions of CIU were lower than those including the engagement dimensions as well. Second, building on Davis’s (2001) diathesis-stress model, we tested the role that self-concept clarity (SCC) and social support play in predicting core CIU in US subjects (NUS = 268). Finally, we expected that, because self-concept clarity is mostly linked to well-being in Western countries, the association between this variable and core CIU would be weak in the Eastern culture sample (NUAE = 270). Our findings confirmed that prevalence figures were 20–40% lower when including the core dimensions only, and that SCC is a key predictor of CIU at low levels of social support in the US. We also confirmed that this is not the case in the UAE. Future research opportunities to advance this study were discussed.

Women's work choices in Kenya: the role of social institutions and household gender attitudes

This study considers the factors that influence women’s work behavior in Kenya. In particular, it examines whether gender attitudes and certain types of social institutions influence the probability of employment or type of employment for women. Using data from the Demographic and Health Survey of 2008–9, we find that religion and ethnicity are significant determinants of women’s employment in Kenya. While personal experience of female genital mutilation is insignificant, spousal age and education differences, as well as marital status (which reflect attitudes both in women’s natal and marital families), are significant determinants of women’s employment choices.

Cohabitation with a B16F10 melanoma-bearer cage mate influences behavior and dendritic cell phenotype in mice

This study evaluated the effects of cohabitation with a B16F10 melanoma-bearer cage mate on behavior and immune functions in mice. Five different experiments were conducted. In each of them, the female mice were divided into two groups: control and experimental. One mouse of each control pair was kept undisturbed and called ""companion of health partner"" (CHP). One mouse of each experimental pair was inoculated with B16FI0 cells and the other, the subject of this study, was called ""companion sick partner"" (CSP). On Day 20 of cohabitation, behavior and immune parameters from CHP and CSP mice were analyzed. In comparison to the CHP, the CSP mice: (1) presented an increased general locomotion in the open field and a decreased exploration time and number of entries in the plus-maze open arms; (2) had an enhanced expression of the CD80 costimulatory molecule on Iab(+)CD11c(+) spleen cells, but no differences were found on lymph nodes cells; (3) presented an altered differentiation of bone marrow cells in the presence of GM-CSF, IL-4, and LPS in vitro, resulting in a lower percentage of Iab(+)CD80(+) cells; (4) had a deficit in the establishment of a Delayed Type of Hypersensitivity to ovalbumin, which was associated to an in vitro proliferation of an IL-10-producing lymphocyte subpopulation after ovalbumin stimulation. Corticosterone levels detected on Day 20 of cohabitation were similar in CHP and CSP mice. It is shown here that DCs phenotype in mice is affected by conditions associated with behavioral alterations indicative of an anxiety-like state induced by the cohabitation with a tumor-bearer conspecific. This phenomenon occurred probably through a nondependent corticosterone mechanism. (C) 2009 Elsevier Inc. All rights reserved.

Circadian phase and intertrial interval interfere with social recognition memory

A modified version of the social habituation/dis-habituation paradigm was employed to examine social recognition memory in Wistar rats during two opposing (active and inactive) circadian phases, using different intertrial intervals (30 and 60 min). Wheel-running activity was monitored continuously to identify circadian phase. To avoid possible masking effects of the light-dark cycle, the rats were synchronized to a skeleton photoperiod, which allowed testing during different circadian phases under identical lighting conditions. In each trial, an infantile intruder was introduced into an adult`s home-cage for a 5-minute interaction session, and social behaviors were registered. Rats were exposed to 5 trials per day for 4 consecutive days: oil days I and 2, each resident was exposed to the same intruder; on days 3 and 4, each resident was exposed to a different intruder in each trial. I he resident`s social investigatory behavior was more intense when different intruders were presented compared to repeated presentation of the same intruder, suggesting social recognition memory. This effect was stronger when the rats were tested during the inactive phase and when the intertrial interval was 60 min, These findings Suggest that social recognition memory, as evaluated in this modified habituation/dis-habituation paradigm, is influenced by the circadian rhythm phase during which testing is performed, and by intertrial interval.

Pregnant Adolescents in Vietnam : Social context and health care needs

Background: The number of childbearing adolescents in Vietnam is relatively low but they are more prone to experience adverse outcome than adult women. Reports of increasing rates of abortion and prevalence of STIs including HIV among youth indicate a need to improve services and counselling for these groups. Midwives are key persons in the promotion of young people’s sexual and reproductive health in Vietnam. Aim: The overall aim of this thesis is to describe the prevalence and outcome of adolescent pregnancies in Vietnam (I), to explore the social context and health care seeking behavior of pregnant adolescents (II), as well as to explore the perspectives of health care providers and midwifery students regarding adolescent sexuality and reproductive health service needs (III, IV). Methods: The studies were conducted from 2002 to 2005, combining qualitative and quantitative research methods. A population based prospective survey was used to estimate rates and outcomes of adolescent pregnancies (I). Pregnant and newly delivered adolescents’ experiences of childbearing and their encounters with health care providers were studied using qualitative interviews (II). Health care providers’ perspective on adolescent sexual and reproductive health (ASRH) and views on how to improve the quality of abortion care was explored in focus group discussions (FGD). The values and attitudes of midwifery students about ASRH were investigated using questionnaires and interviews (IV). Descriptive statistics was used to analyse quantitative data (I, IV) and content analysis were applied for qualitative data (II, III, and IV). Findings: Adolescent birth rate was similar to previously reported in Vietnam but lower when compared to other Asian countries. The incidence of stillborn among adolescents was higher than for women in higher reproductive ages. The proportion of preterm deliveries was 20 % of all births, higher than previous findings from Vietnam. About 2 % of the deliveries were home deliveries, more common among women with low education, belonging to ethnic minority and/or living in mountainous areas (I). Ambivalence facing motherhood, pride and happiness but also worries and lack of self-confidence emerged as themes from the interviews; and experience of ‘being in the hands of others’ in a positive, caring sense but also in a sense of subordination in relation to husband, family and health care providers (II). Health care providers at abortion clinics and midwifery students generally disapproved of pre-marital sex, but had a pragmatic view on the need for contraceptive services and counselling to reduce the burden of unwanted pregnancies and abortions for young women. Providers and midwifery students expressed a need for training on ASRH issues (III, IV). Conclusion: Cultural norms and gender inequity make pregnant adolescent women in Vietnam vulnerable to sexual and reproductive health risks. Health care providers experience ethical dilemmas while counselling unmarried adolescents who come for abortion and this has a negative impact on the quality of care. Integrated ASRH in education and training programmes for health care providers, including midwives, as well as continued in-service training on these issues are suggested to improve reproductive health care services in Vietnam.

Marketing Social Change: A Comparative Historical and Methodological Analysis of Anti-Smoking Endeavors

Even though assessing social marketing endeavors proves to be challenging, evaluators can learn from previous campaigns and identify which facets of social marketing events, programs and campaigns need to be improved. Additionally, by analyzing social movements and evaluating how they connect to social marketing, we can gain a clearer view on ways to ameliorate the field of social marketing. As social marketing becomes increasingly sophisticated and similar to commercial marketing, there is hope that social marketing can yield higher rates of success in the future. Friend and Levy (2002) claimed that it was nearly impossible to compare social marketing endeavors using quantitative criteria and advocate the use of qualitative methods. However, if social marketing scholars developed a more systematic paradigm to assess events, programs and campaigns employing a combination of both quantitative and qualitative methods, then it would be easier to establish which social marketing efforts generated more success than others. When there are too many confounding variables, conclusions cannot always be drawn and evaluations may not be viewed as legitimate. As a result, critics become skeptical of social marketing’s value and both the importance and credibility of social marketing decline. With the establishment of proper criteria and evaluation methods, social marketing can progress and initiate more social change.

Escolha social e valores irredutíveis: uma aproximação da economia política e a ideologia

No presente paper, nós provamos que qualquer função da escolha social satisfaz o princípio da independência das alternativas irrelevantes (IIA) de Arrow se o comportamento individual é menu-dependente. Portanto, o 'Teorema da Possibilidade Geral' de Arrow não é válido quando as preferências individuais são determinadas por valores irredutíveis. Nesse contexto, qualquer instrumento de agregação que satisfaça os princípios não-ditatoriais e paretianos de unanimidade (maioria simples, por exemplo) também faz IIA. Esse poderia ser um resultado importante para a teoria da escolha social, enquanto um comportamento individual determinado por valores irredutíveis (interesse próprio, ideologia, Ética e normas sociais, por exemplo) podendo validar democracia representativa. A importância relativa de tais valores e da possibilidade de reversão da preferência determina a dinâmica da escolha social, de acordo com os princípios democráticos.

Responsabilidade social das empresas e valores humanos: um estudo sobre a atitude dos gestores brasileiros

In the last decades of the 21st century, Corporate Social Responsibility (CSR) has become one of the most widely debated issues in business management, concerning researchers, politicians, managers and society at large. With multilateral implications in economic and social life, CSR refers, essentially, to the discussion about the boundaries of business intervention in society and the ethical limits that should regulate that intervention. It questions the impact of business practices in social well-being, the role left for corporations and for the State in attending to community needs, and which are, at last, the responsibilities that tie enterprises to society. In this research, CSR is approached from the perspective of its ethical foundations, based on the moral reasoning of the business manager, as a key organizational leader with relevant decision power. Specifically, the research aims to understand how the personal human value system and the ethical orientation of managers influence their attitude towards CSR, considering this attitude as an indicator of managerial behavior that translates into corporate performance. Theoretically, CSR concept is discussed and presented as a set of social commitments, based on a strict interpretation of its meaning. As to human values, its philosophical roots are briefly analyzed and Schwartz modern motivational theory is addressed as main reference for studying the personal value system of managers in this research. Concerning ethics, based on classical theory from moral philosophy, references are seek in John Stuart Mill¿s utilitarianism, Immanuel Kant¿s deontological absolutism, John Rawls¿s theory of justice and the ethics of virtue inspired by Aristotle¿s moral thoughts. Based on an extended literature review, research hypothesis are proposed as part of a theoretical model of analysis named Individual Attitude Towards Social Responsibility Model. In order to test the theory¿s empirical validity, it was conducted a field study with 252 Brazilian managers, mainly from the metropolitan areas of São Paulo and Rio de Janeiro. Results show that managerial attitude aligned with CSR principles is favored by conservative personal values, protectors of stability and centered on collective will, and by an ethical orientation based on egalitarianism as postulated by distributive justice principles. However, results also show that the influence of values and personal ethics on managerial attitude towards CSR only occur in managers younger than 30 years old. Findings and their meanings are discussed, as well as summarized in the Axiological and Ethical Determinants of Managers¿ Social Commitment Model. Finally, methodological limitations are evaluated and clues for further research are suggested.

A representação social do fenômeno participativo em organizações publicas do Rio de Janeiro

O presente trabalho, tomando como referencial a teoria das representações sociais, propõe-se a esboçar, a partir dos resultados de uma pesquisa empírica realizada junto a uma amostra privilegiada de servidores públicos, o campo comunicacional pelos quais se define o lugar da participação no contexto da administração pública do Estado. No âmbito teórico destacou-se a relação entre representação social e comportamento, conferindo uma maior ênfase na análise das propriedades estruturais da representação através da identificação de seu núcleo central e de seu sistema periférico associado. Os resultados indicam que, longe de estimular práticas corporativas, a adoção de formas participativas de gestão pode contribuir para a construção de um modelo de administração pública que responda aos requisitos de eficiência, eficácia e efetividade.

Responsabilidade social corporativa em períodos de desaquecimento econômico: o comprometimento das empresas com seus funcionários

o estudo objetivou verificar se empresas comprometidas com questões sociais, ambientais e trabalhistas, e que adotam instrumentos de gestão baseados na valorização da diversidade e de princípios éticos, sustentam esses valores mesmo em períodos recessivos de nossa economia. Para responder essa questão, analisamos o comportamento de empresas socialmente responsáveis com os seus empregados durante o período compreendido entre 1988 e 2000. As empresas selecionadas foram avaliadas como socialmente responsáveis pelo Instituto Ethos de Responsabilidade Social e compõem o fundo de investimento Ethical do Banco Real Os resultados da pesquisa demonstram a existência de uma falta de coerência entre o discurso e a prática da responsabilidade social corporativa pelas empresas.

A influência do capital social e do comportamento de cidadania organizacional na satisfação de vida e desempenho no trabalho: um estudo comparativo entre Brasil e Portugal

Desde à muito, os temas, capital social e comportamento de cidadania organizacional (CCO) têm sido extensivamente pesquisado e estudados nos EUA, no entanto estes têm recebido pouca relevância a nível de outros contextos internacionais. Se por um lado, a sua importância e inferência na performance dentro do contexto empresarial têm sido crescente, caracterizando a necessidade de um entendimento cada vez maior por parte das empresas, por outro, o investimento das corporações de grande porte, caminham cada vez mais em direção dos países com crescimento exponencial sustentado, como são o BRIC, o que cna uma necessidade fomentada de pesquisa nesta área de pesquisa para estas regiões. Este estudo pretendeu investigar, avaliar e mapear a influência do capital e do CCO na satisfação de vida e desempenho no trabalho do funcionário de nível superior, no contexto empresarial brasileiro e português, com o objetivo de identificar quais as diferenças existentes nestes duas realidade, devido ao investimento crescente do segundo para com o primeiro. Genericamente, encontramos clara influência das dimensões do CCO tanto para o desempenho no trabalho como para a satisfação de vida do trabalhador, assim como presença também marcada das duas dimensões do capital Social. Mais especificamente, foi entendido pelo nosso estudo que a realidade empresarial brasileira necessita que as empresas criem mecanismos que fomentem os laços entre colegas, a conscienciosidade, altruísmo e virtude cívica dos seus funcionários, pois assim aumentará o desempenho. Já para o contexto português, apenas a conscienciosidade e a virtude apresentaram significativa relação. Desta forma, conclui-se que para o investimento das empresas português no Brasil, estas precisam ter atenção à dimensão estrutural - relação com colegas - promovendo-a e à necessidade patente que os brasileiros têm de ajudar os seus colegas - comportamento altruísta - para aumentar o desempenho no trabalho. No que se refere a satisfação de vida, que se mostrou estreitamente relacionada com o desempenho, o brasileiro apenas precisa notar confiança nos colegas, senti-se altruísta e consciencioso, ao passo que o português necessita criar fortes laços com os colegas, mas não fomentar o comportamento altruístico. Desta forma as empresas investidoras apenas precisam ter atenção mais uma vez a necessidade de prestar ajuda especifica que o brasileiro sente, promovendo workshops com os próprios funcionários, por forma a estes passarem o seu conhecimento, monitorias, estágios, entre outros. Estes resultados demonstraram que cada continente, país (possuidor ou não da mesma língua) e/ou cultura comporta diferenças significativas no contexto empresarial, assim tornase difícil implementar técnicas e comportamentos internacionais e esperar que os resultados sejam exatamente iguais. Este estudo espera dar alguns instrumentos de comparação para que as empresas portuguesas entendam, a este nível, a realidade brasileira.

The effect of social security, health, demography and technology on retirement

This article studies the determinants of the labor force participation of the elderly and investigates the factors that may account for the increase in retirement in the second half of the last century. We develop a life-cycle general equilibrium model with endogenous retirement that embeds Social Security legislation and Medicare. Individuals are ex ante heterogeneous with respect to their preferences for leisure and face uncertainty about labor productivity, health status and out-of-pocket medical expenses. The model is calibrated to the U.S. economy in 2000 and is able to reproduce very closely the retirement behavior of the American population. It reproduces the peaks in the distribution of Social Security applications at ages 62 and 65 and the observed facts that low earners and unhealthy individuals retire earlier. It also matches very closely the increase in retirement from 1950 to 2000. Changes in Social Security policy - which became much more generous - and the introduction of Medicare account for most of the expansion of retirement. In contrast, the isolated impact of the increase in longevity was a delaying of retirement.
