Accessing external innovation in drug discovery and development.

Tufféry, Pierre

2015-06-01

A decline in the productivity of the pharmaceutical industry research and development (R&D) pipeline has highlighted the need to reconsider the classical strategies of drug discovery and development, which are based on internal resources, and to identify new means to improve the drug discovery process. Accepting that the combination of internal and external ideas can improve innovation, ways to access external innovation, that is, opening projects to external contributions, have recently been sought. In this review, the authors look at a number of external innovation opportunities. These include increased interactions with academia via academic centers of excellence/innovation centers, better communication on projects using crowdsourcing or social media and new models centered on external providers such as built-to-buy startups or virtual pharmaceutical companies. The buzz for accessing external innovation relies on the pharmaceutical industry's major challenge to improve R&D productivity, a conjuncture favorable to increase interactions with academia and new business models supporting access to external innovation. So far, access to external innovation has mostly been considered during early stages of drug development, and there is room for enhancement. First outcomes suggest that external innovation should become part of drug development in the long term. However, the balance between internal and external developments in drug discovery can vary largely depending on the company strategies.

Smoking bans and the secondhand smoking problem: an economic analysis.

Hofmann, Annette; Nell, Martin

Smoking bans are gaining widespread support in the European Union and other countries. The vast majority of these bans are partial bans given that smoking is still permitted in certain places. This article investigates the role of partial smoking bans in coping with externalities caused by the secondhand smoking problem. Although it is widely known that Pigouvian taxation is superior to a perfect ban, this result does not necessarily carry over to a partial ban because taxes cannot (easily) be differentiated according to location. We show that under an easy and intuitive condition, (1) enacting a partial smoking ban alone always improves social welfare (a) in an unregulated society and (b) even in a regulated society if externalities can be eliminated, and (2) it is ensured that a combination of Pigouvian tax and a partial smoking ban leads to a higher social optimum than implementing corrective Pigouvian taxation alone.

Institutional narratives in the discourse between oncology social workers and cancer patients' self-help organization.

Kacen, Lea; Bakshy, Iris

2005-09-01

In this study, the authors examine a discourse between members of a cancer patients' self-help organization (CP-SHO) and oncological social workers (OSWs) on support groups for cancer patients. Eight OSWs and 8 CP-SHO volunteers served as the key research population. Using the interpretive-narrative approach to research, the authors apply a variety of data collection methods and a combination of data analysis methods: narrative analysis and discourse analysis. The findings point to the simultaneous existence of two institutional narratives for each organization, one internal and the other external. Discourse between the organizations takes place mainly at the external institutional narrative level, with each body maintaining the mistaken impression that the other's perception of reality is similar to its own (false consensus). In the meantime, the internal narratives that attest to the latent meaning of the discourse govern the interaction and prevent effective dialogue between the respective organizations.

Cognitive Abilities, Social Adaptation, and Externalizing Behavior Problems in Childhood and Adolescence: Specific Cascade Effects Across Development.

Children's and adolescents' cognitive abilities, social adaptation, and externalizing behaviors are broadly associated with each other at the bivariate level; however, the direction, ordering, and uniqueness of these associations have yet to be identified. Developmental cascade models are particularly well-suited to (1) discern unique pathways among psychological domains and (2) model stability in and covariation among constructs, allowing for conservative tests of longitudinal associations. The current study aimed to identify specific cascade effects among children's cognitive abilities, social adaptation, and externalizing behaviors, beginning in preschool and extending through adolescence. Children (46.2 % female) and mothers (N = 351 families) provided data when children were 4, 10, and 14 years old. Cascade effects highlighted significant stability in these domains. Unique longitudinal associations were identified between (1) age-10 cognitive abilities and age-14 social adaptation, (2) age-4 social adaptation and age-10 externalizing behavior, and (3) age-10 externalizing behavior and age-14 social adaptation. These findings suggest that children's social adaptation in preschool and externalizing behavior in middle childhood may be ideal intervention targets to enhance adolescent well-being.

Sibling relationship patterns and their associations with child competence and problem behavior.

Buist, Kirsten L; Vermande, Marjolijn

2014-08-01

The present study is the first to examine patterns in sibling relationship quality and the associations of these patterns with internalizing and externalizing problem behavior, as well as self-perceived competence, in middle childhood. Self-report questionnaires (e.g., Sibling Relationship Questionnaire, Self-Perception Profile for Children, Youth Self Report) were administered among 1,670 Dutch children (Mage = 11.40 years, SD = .83) attending 51 different Dutch schools. Three sibling relationship clusters were found: a conflictual cluster (low on warmth, high on conflict), an affect-intense cluster (above average on warmth and conflict), and a harmonious cluster (high on warmth, low on conflict). Sister pairs were underrepresented in the conflictual cluster and overrepresented in the harmonious cluster. Children with conflictual sibling relationships reported significantly more internalizing and externalizing problems, and lower academic and social competence and global self-worth, than children with harmonious sibling relationships. Children with affect-intense sibling relationships reported less aggression and better social competence than children with conflictual sibling relationships. Our findings indicate that it is fruitful to combine indices of sibling warmth and conflict to examine sibling relationship types. Relationship types differed significantly concerning internalizing and externalizing problems, but also concerning self-perceived competence. These findings extend our knowledge about sibling relationship types and their impact on different aspects of child adjustment. Whereas harmonious sibling relationships are the most beneficial for adjustment, sibling conflict mainly has a negative effect on adjustment in combination with lack of sibling warmth. Implications and future directions are discussed.

Aims: To examine the influence of country-level characteristics and individual socio-economic status (SES) on individual alcohol-related consequences. Methods: Data from 42,655 men and women collected by cross-sectional surveys in 25 countries of the Gender, Alcohol and Culture: An International Study study were used. The individual SES was measured by the highest attained educational level. Alcohol-related consequences were defined as the self-report of at least one internal or one external consequence in the last year. The relationship between individuals’ education and alcohol-related consequences was examined by meta-analysis. In a second step, the individual level data and country data were combined in multilevel models. As country-level indicators, we used the purchasing power parity of the gross national income (GNI), the Gini coefficient and the Gender Gap Index. Results: Lower educated men and women were more likely to report consequences than higher educated men and women even after controlling for drinking patterns. For men, this relation was significant for both internal and external problems. For women, it was only significant for external problems. The GNI was significantly associated with reporting external consequences for men such that in lower income countries men were more likely to report social problems. Conclusion: The fact that problems accrue more quickly for lower educated persons even if they drink in the same manner can be linked to the social or environmental dimension surrounding problems. That is, those of fewer resources are less protected from the experience of a problem or the impact of a stressful life event. PMID:22542707

The Difference Between Ice Cream and Nazis: Moral Externalization and the Evolution of Human Cooperation.

PubMed

Stanford, P Kyle

2017-07-06

A range of empirical findings are first used to more precisely characterize our distinctive tendency to objectify or externalize moral demands, and it is then argued that this salient feature of our moral cognition represents a profound puzzle for evolutionary approaches to human moral psychology that existing proposals do not help to resolve. It is then proposed that such externalization facilitated a broader shift to a vastly more cooperative form of social life by establishing and maintaining a connection between the extent to which an agent is herself motivated by a given moral norm and the extent to which she uses conformity to that same norm as a criterion in evaluating candidate partners in social interaction generally. This connection ensures the correlated interaction necessary to protect those prepared to adopt increasingly cooperative, altruistic, and other prosocial norms of interaction from exploitation, especially as such norms were applied in novel ways and/or to novel circumstances and as the rapid establishment of new norms allowed us to reap still greater rewards from hypercooperation. A wide range of empirical findings are then used to support this hypothesis, showing why the status we ascribe to moral demands and considerations exhibits the otherwise puzzling combination of objective and subjective elements that it does as well as showing how the need to effectively advertise our externalization of particular moral commitments generates features of our social interaction so familiar that they rarely strike us as standing in need of any explanation in the first place.

Eating behavior in Portuguese higher education students: the effect of social desirability.

Poínhos, Rui; Oliveira, Bruno M P M; Correia, Flora

2015-02-01

The aim of this study was to relate social desirability with eating behavior dimensions among higher education students in Portugal, and to assess the effect of social desirability on the association between pairs of eating behavior dimensions. Data from 266 higher education students (62.8% women) aged between 18 and 27 y were evaluated. Social desirability and several eating behavior dimensions (emotional and external eating, flexible and rigid restraint, binge eating, and eating self-efficacy) were assessed. In both women and men, social desirability showed negative associations with emotional, external, and binge eating, and positive associations with eating self-efficacy. For the majority of the correlations, the control for social desirability led to a decrease in the strength of the association: Social desirability showed a greater effect on the associations between external and binge eating, external eating and eating self-efficacy, binge eating and eating self-efficacy, and emotional and external eating. This study demonstrated that social desirability should be considered when assessing the dimensions of eating behavior, namely eating self-efficacy and dimensions related to overeating.

A tenth of all people who inject drugs in Kenya are women, yet their social contexts and experiences remain poorly understood. This paper reports how multiple forms of stigma are experienced by women who inject drugs in coastal Kenya and the impact that they have on their ability to access essential health services. In 2015, in-depth interviews and focus group discussions were held with 45 women who inject drugs in two coastal towns. These data were supplemented with in-depth interviews with five individual stakeholders involved in service provision to this population. Data were analyzed thematically using NVivo. Women who inject drugs experience multiple stigmas, often simultaneously. These included the external stigma and self-stigma of injection drug use, external gender-related stigma of being a female injecting drug user, and the external stigma of being HIV positive (i.e., among those living with HIV). Stigma led to rejection, social exclusion, low self-esteem, and delay or denial of services at health facilities. HIV and harm reduction programs should incorporate interventions that address different forms of stigma among women who inject drugs in coastal Kenya. Addressing stigma will require a combination of individual, social, and structural interventions, such as collective empowerment of injecting drug users, training of healthcare providers on issues and needs of women who inject drugs, peer accompaniment to health facilities, addressing wider social determinants of stigma and discrimination, and expansion of harm reduction interventions to change perceptions of communities towards women who inject drugs.

Peer influences on internalizing and externalizing problems among adolescents: a longitudinal social network analysis.

Fortuin, Janna; van Geel, Mitch; Vedder, Paul

2015-04-01

Adolescents who like each other may become more similar to each other with regard to internalizing and externalizing problems, though it is not yet clear which social mechanisms explain these similarities. In this longitudinal study, we analyzed four mechanisms that may explain similarity in adolescent peer networks with regard to externalizing and internalizing problems: selection, socialization, avoidance and withdrawal. At three moments during one school-year, we asked 542 adolescents (8th grade, M-age = 13.3 years, 51 % female) to report who they liked in their classroom, and their own internalizing and externalizing problems. Adolescents tend to prefer peers who have similar externalizing problem scores, but no significant selection effect was found for internalizing problems. Adolescents who share the same group of friends socialize each other and then become more similar with respect to externalizing problems, but not with respect to internalizing problems. We found no significant effects for avoidance or withdrawal. Adolescents may choose to belong to a peer group that is similar to them in terms of externalizing problem behaviors, and through peer group socialization (e.g., enticing, modelling, mimicking, and peer pressure) become more similar to that group over time.

[Musculoskeletal system as a target organ of a frailty processes].

PubMed

Zlobina, I A; Krivtsunov, A N; Bogat, S V; Prashchayeu, K I

Pathology of the musculoskeletal system is widespread in the population and is one of the most common diseases of patients in older age groups. The most significant of them are osteoporosis, osteoarthritis and sarcopenia. All three components separately, of course, lead to lower quality of life. In our work we show the mechanisms of interference of these states at each other, and their combined impact on the musculoskeletal system as a target organ processes senile asthenia. Osteoarthritis, osteoporosis, and sarcopenia, and especially their combination lead to hypomobility. Hypomobility under the influence of external factors is one of the leading syndromes potentiating aggravation processes senile asthenia. Thus, the mechanism of re-entry is triggered, and a vicious circle leading to fatal medical-social and social consequences. It is shown that changes in the musculoskeletal system should be considered as a single aging within senile asthenia, and all used and newly created medical and social rehabilitation and prevention programs should be integrated in nature.

RELATIONS BETWEEN PSYCHOPATHY FACETS AND EXTERNALIZING IN A CRIMINAL OFFENDER SAMPLE

Patrick, Christopher J.; Hicks, Brian M.; Krueger, Robert F.; Lang, Alan R.

2008-01-01

The construct of psychopathy is viewed as comprising distinctive but correlated affective-interpersonal and social deviance facets. Here, we examined these facets of Hare's Psychopathy Checklist-Revised (PCL-R) in terms of their associations with the externalizing dimension of adult psychopathology, defined as the common factor underlying symptoms of conduct disorder, adult antisocial behavior, alcohol use/abuse, and drug abuse, along with disinhibitory personality traits. Correlational analyses revealed a strong relationship between this externalizing dimension and the social deviance facet of psychopathy (r = .84), and a lesser relationship with the emotional-interpersonal component (r = .44). Structural models controlling for the moderate overlap between the PCL-R factors revealed that externalizing was substantially related to the unique variance in the social deviance features of psychopathy, but unrelated to the unique variance of the emotional and interpersonal features whether modeled together or as separate factors. These results indicate that the social deviance factor of the PCL-R reflects the externalizing dimension of psychopathology, whereas the emotional-interpersonal component taps something distinct aside from externalizing. In addition, based on our finding of an association between PCL-R social deviance and externalizing, we were able to predict new relations between this facet of psychopathy and criterion variables, including nicotine use and gambling, that have previously been linked to externalizing. Implications for future research on the causes and correlates of psychopathy are discussed. PMID:16178678

Social life and sanitary risks: evolutionary and current ecological conditions determine waste management in leaf-cutting ants.

Adequate waste management is vital for the success of social life, because waste accumulation increases sanitary risks in dense societies. We explored why different leaf-cutting ants (LCA) species locate their waste in internal nest chambers or external piles, including ecological context and accounting for phylogenetic relations. We propose that waste location depends on whether the environmental conditions enhance or reduce the risk of infection. We obtained the geographical range, habitat and refuse location of LCA from published literature, and experimentally determined whether pathogens on ant waste survived to the high soil temperatures typical of xeric habitats. The habitat of the LCA determined waste location after phylogenetic correction: species with external waste piles mainly occur in xeric environments, whereas those with internal waste chambers mainly inhabit more humid habitats. The ancestral reconstruction suggests that dumping waste externally is less derived than digging waste nest chambers. Empirical results showed that high soil surface temperatures reduce pathogen prevalence from LCA waste. We proposed that LCA living in environments unfavourable for pathogens (i.e. xeric habitats) avoid digging costs by dumping the refuse above ground. Conversely, in environments suitable for pathogens, LCA species prevent the spread of diseases by storing waste underground, presumably, a behaviour that contributed to the colonization of humid habitats. These results highlight the adaptation of organisms to the hygienic challenges of social living, and illustrate how sanitary behaviours can result from a combination of evolutionary history and current environmental conditions. © 2016 The Author(s).

Crossing boundaries in interprofessional education: A call for instructional integration of two script concepts.

2016-09-01

Clinical work occurs in a context which is heavily influenced by social interactions. The absence of theoretical frameworks underpinning the design of collaborative learning has become a roadblock for interprofessional education (IPE). This article proposes a script-based framework for the design of IPE. This framework provides suggestions for designing learning environments intended to foster competences we feel are fundamental to successful interprofessional care. The current literature describes two script concepts: "illness scripts" and "internal/external collaboration scripts". Illness scripts are specific knowledge structures that link general disease categories and specific examples of diseases. "Internal collaboration scripts" refer to an individual's knowledge about how to interact with others in a social situation. "External collaboration scripts" are instructional scaffolds designed to help groups collaborate. Instructional research relating to illness scripts and internal collaboration scripts supports (a) putting learners in authentic situations in which they need to engage in clinical reasoning, and (b) scaffolding their interaction with others with "external collaboration scripts". Thus, well-established experiential instructional approaches should be combined with more fine-grained script-based scaffolding approaches. The resulting script-based framework offers instructional designers insights into how students can be supported to develop the necessary skills to master complex interprofessional clinical situations.

An innovation diffusion model of a local electricity network that is influenced by internal and external factors

Hattam, Laura; Greetham, Danica Vukadinović

2018-01-01

Haynes et al. (1977) derived a nonlinear differential equation to determine the spread of innovations within a social network across space and time. This model depends upon the imitators and the innovators within the social system, where the imitators respond to internal influences, whilst the innovators react to external factors. Here, this differential equation is applied to simulate the uptake of a low-carbon technology (LCT) within a real local electricity network that is situated in the UK. This network comprises of many households that are assigned to certain feeders. Firstly, travelling wave solutions of Haynes' model are used to predict adoption times as a function of the imitation and innovation influences. Then, the grid that represents the electricity network is created so that the finite element method (FEM) can be implemented. Next, innovation diffusion is modelled with Haynes' equation and the FEM, where varying magnitudes of the internal and external pressures are imposed. Consequently, the impact of these model parameters is investigated. Moreover, LCT adoption trajectories at fixed feeder locations are calculated, which give a macroscopic understanding of the uptake behaviour at specific network sites. Lastly, the adoption of LCTs at a household level is examined, where microscopic and macroscopic approaches are combined.

Tracking Effects of Problematic Social Networking on Adolescent Psychopathology: The Mediating Role of Sleep Disruptions.

2017-01-01

Concerns are growing about adolescents' problematic social networking and possible links to depressed mood and externalizing behavior. Yet there remains little understanding of underlying processes that may account for these associations, including the mediating role of sleep disruption. This study tests this putative mediating process and examines change in problematic social networking investment and disrupted sleep, in relation to change in depressed mood and externalizing behavior. A sample of 874 students (41% male; 57.2% Caucasian; baseline M age = 14.4 years) from 27 high schools were surveyed. Participants' problematic social networking, sleep disruption, and psychopathology (depressed mood, externalizing behaviors) were measured annually over 3 years. Longitudinal mediation was tested using latent trajectories of problematic social networking use, sleep disruption, and psychopathology. Both problematic social networking and sleep disruption underwent positive linear growth over time. Adolescents who increasingly invested in social networking reported increased depressed mood, with around 53% of this association explained by the indirect effect of increased sleep disruptions. Further, adolescents who increasingly invested in social networking also reported increased externalizing behavior; some of this relation was explained (13%) via increased sleep disruptions. However an alternative model in which increased externalizing was associated with increased social networking, mediated by sleep disruptions, indicated a reciprocal relation of similar magnitude. It is important for parents, teachers, and psychologists to minimize the negative effects of social networking on adolescents' psychopathology. Interventions should potentially target promoting healthy sleep habits through reductions in social networking investment and rescheduling usage away from bedtime.

Freshman, Brenda; Rubino, Louis

2004-01-01

For healthcare organizations to survive in these increasingly challenging times, leadership and management must face mounting interpersonal concerns. The authors present the boundaries of internal and external social networks with respect to leadership and managerial functions: Social networks within the organization are stretched by reductions in available resources and structural ambiguity, whereas external social networks are stressed by interorganizational competitive pressures. The authors present the development of emotional intelligence skills in employees as a strategic training objective that can strengthen the internal and external social networks of healthcare organizations. The authors delineate the unique functions of leadership and management with respect to the application of emotional intelligence skills and discuss training and future research implications for emotional intelligence skill sets and social networks.

Internal and external factors affecting the development of neuropathic pain in rodents. Is it all about pain?

PubMed

Vissers, K; De Jongh, R; Hoffmann, V; Heylen, R; Crul, B; Meert, T

2003-12-01

It is important to know the factors that will influence animal models of neuropathic pain. A good reproducibility and predictability in different strains of animals for a given test increases the clinical relevance and possible targeting. An obligatory requirement for enabling comparisons of results of different origin is a meticulous definition of the specific sensitivities of a model for neuropathic pain and a description of the test conditions. Factors influencing neuropathic pain behavior can be subdivided in external and internal factors. The most important external factors are; timing of the measurement of pain after induction of neuropathy, circadian rhythms, seasonal influences, air humidity, influence of order of testing, diet, social variables, housing and manipulation, cage density, sexual activity, external stress factors, and influences of the experimenter. The internal factors are related to the type of animal, its genetic background, gender, age, and the presence of homeostatic adaptation mechanisms to specific situations or stress. In practice, the behavioral presentations to pain depend on the combination of genetic and environmental factors such as accepted social behavior. It also depends on the use of genetic manipulation of the animals such as in transgenic animals. These make the interpretation of data even more difficult. Differences of pain behavior between in- and outbred animals will be better understood by using modern analysis techniques. Substrains of animals with a high likelihood for developing neuropathic pain make the unraveling of specific pathophysiological mechanisms possible. Concerning the effect of stress on pain, it is important to differentiate between external and internal stress such as social coping behavior. The individual dealing with this stress is species sensitive, and depends on the genotype and the social learning. In the future, histo-immunological and genetic analysis will highlight similarities of the different pathophysiological mechanisms of pain between different species and human subjects. The final objective for the study of pain is to describe the genetics of the eliciting pain mechanisms in humans and to look for correlations with the knowledge from basic research. Therefore, it is necessary to know the genetic evolution of the different mechanisms in chronic pain. In order to be able to control the clinical predictability of a putative treatment the evolutionary pharmacogenomic structure of specific transmitters and receptors must be clarified.

2017-01-01

For the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) together, this study examined support for a bifactor model, and also the internal consistency reliability and external validity of the factors in this model. Participants ( N = 526) were adults from the general community who completed the SPS and SIAS. Confirmatory factor analysis (CFA) of their ratings indicated good support for the bifactor model. For this model, the loadings for all but six items were higher on the general factor than the specific factors. The three positively worded items had negligible loadings on the general factor. The general factor explained most of the common variance in the SPS and SIAS, and demonstrated good model-based internal consistency reliability (omega hierarchical) and a strong association with fear of negative evaluation and extraversion. The practical implications of the findings for the utilization of the SPS and SIAS, and the theoretical and clinical implications for social anxiety are discussed.

Internal and external attention in speech anxiety.

Cognitive models of social phobia propose that socially anxious individuals engage in heightened self-focused attention. Evidence for this assumption was provided by dot probe and feedback tasks measuring attention and reactions to internal cues. However, it is unclear whether similar patterns of attentional processing can be revealed while participants actually engage in a social situation. The current study used a novel paradigm, simultaneously measuring attention to internal and external stimuli in anticipation of and during a speech task. Participants with speech anxiety and non-anxious controls were asked to press a button in response to external or internal probes, while giving a speech on a controversial topic in front of an audience. The external probe consisted of a LED attached to the head of one spectator and the internal probe was a light vibration, which ostensibly signaled changes in participants' pulse or skin conductance. The results indicate that during speech anticipation, high speech anxious participants responded significantly faster to internal probes than low speech anxious participants, while during the speech no differences were revealed between internal and external probes. Generalization of our results is restricted to speech anxious individuals. Our results provide support for the pivotal role of self-focused attention in anticipatory social anxiety. Furthermore, they provide a new framework for understanding interaction effects of internal and external attention in anticipation of and during actual social situations.

We introduce a simple model of opinion dynamics in which a two-state agent modified Sznajd model evolves due to the simultaneous action of stochastic driving and a periodic signal. The stochastic effect mimics a social temperature, so the agents may adopt decisions in support for or against some opinion or position, according to a modified Sznajd rule with a varying probability. The external force represents a simplified picture by which society feels the influence of the external effects of propaganda. By means of Monte Carlo simulations we have shown the dynamical interplay between the social condition or mood and the external influence, finding a stochastic resonance-like phenomenon when we depict the noise-to-signal ratio as a function of the social temperature. In addition, we have also studied the effects of the system size and the external signal strength on the opinion formation dynamics.

2009-01-01

Relations among externalizing behavior, therapeutic context (community care vs. residential care), and social problem-solving by children with mild intellectual disabilities or borderline intelligence were examined. Participants were 186 children (12 to 14 years of age) who responded to a video-based social problem-solving task. Of these, 130 received residential care and the majority suffered from severe externalizing behavior problems. The results indicated that externalizing behavior was related to encoding, generation of aggressive responses, and negative evaluation of assertive responses. Therapeutic context was related to encoding, positive evaluation of assertive responses, and negative evaluation of aggressive responses. Results indicate a discrepancy between appropriate problem-solving skills and behavior in daily life. Implications for interventions are discussed.

Relationship among prospective parents' locus of control, social desirability, and choice of psychoprophylaxis.

Windwer, C

1977-01-01

This study sought to determine if there is a relationship among locus of control, social desirability, and choice of psychoprophylaxis (PPM). It was hypothesized that internal locus of control and low social desirability would correlate significantly with the choice of PPM by husbands and wives; that externally controlled wives who participated in PPM would have more internally controlled husbands than externally controlled wives who participated in PPM would have more internally controlled husbands than externally controlled wives who did not participate; and that locus of control and social desirability, when taken together, would be better predictors of choice of PPM than either taken separately. Ninety-eight middle-class nulliparous couples, participant and non-participant, were studied in the seventh or eighth month of the wife's pregnancy. Rotter's I-E Scale and the Marlowe-Crowne Social Desirability Scale were used to measure locus of control and social desirability. Study findings did not support the hypotheses.

How events determine spreading patterns: information transmission via internal and external influences on social networks

Liu, Chuang; Zhan, Xiu-Xiu; Zhang, Zi-Ke; Sun, Gui-Quan; Hui, Pak Ming

2015-11-01

Recently, information transmission models motivated by the classical epidemic propagation, have been applied to a wide-range of social systems, generally assume that information mainly transmits among individuals via peer-to-peer interactions on social networks. In this paper, we consider one more approach for users to get information: the out-of-social-network influence. Empirical analyzes of eight typical events’ diffusion on a very large micro-blogging system, Sina Weibo, show that the external influence has significant impact on information spreading along with social activities. In addition, we propose a theoretical model to interpret the spreading process via both internal and external channels, considering three essential properties: (i) memory effect; (ii) role of spreaders; and (iii) non-redundancy of contacts. Experimental and mathematical results indicate that the information indeed spreads much quicker and broader with mutual effects of the internal and external influences. More importantly, the present model reveals that the event characteristic would highly determine the essential spreading patterns once the network structure is established. The results may shed some light on the in-depth understanding of the underlying dynamics of information transmission on real social networks.

Risk communication and human biomonitoring: which practical lessons from the Belgian experience are of use for the EU perspective?

PubMed

Keune, Hans; Morrens, Bert; Loots, Ilse

2008-06-05

In order to investigate and monitor environmental health in Flanders (the Dutch speaking part of Belgium), the Flemish government funded the Centre of Expertise for Environment and Health, which started a human biomonitoring campaign in 2001. In addition to environmental health experts measuring environmental pollutants and health effects in human beings, social scientific experts at the Centre focus on risk communication associated with the human biomonitoring campaign. In the literature about risk communication an evolution can be traced from traditional, one-way communication, restricted to the dissemination of information from experts to the public, to more modern, two-way risk communication, with a focus on participation and cooperation between scientists, policy-makers and the public.Within the Centre of Expertise for Environment and Health this discourse was first translated into some general principles and guidelines for external communication, at a 'Ten Commandments level'. These principles needed to be incorporated in the day-to-day practice of human biomonitoring research. The social scientific experts at the Centre developed a combined risk communication strategy. On the one hand the strategy consists of traditional risk communication for external communication purposes, for example information meetings and digital newsletters. On the other hand it consists of a step by step approach of incorporating more modern risk communication, for example a risk perception questionnaire, dialogical experiments for involving local stakeholders, and an action-plan for interpreting results for policy making. With a parallel strategy of traditional and modern communication, of external and internal reflection, and through different social scientific projects, the Flemish Centre of Expertise of Environment and Health incorporates risk communication in the day-to-day practice of human biomonitoring research. A direct and continuous involvement of the social scientist, an openness between all colleagues involved, and the awareness of a fine balance between quality and practicability are important success factors. These lessons may be helpful and inspirational for a European human biomonitoring project.

Peer Victimization and Social Alienation: Predicting Deviant Peer Affiliation in Middle School

2013-01-01

Two prospective studies examined a theoretical model wherein exposure to victimization, resulting from early behavioral risk, heightens children’s social alienation and subsequent deviant peer affiliation (DPA). Across Study 1 (298 girls, 287 boys; K – 7th grade; 5 – 12 years) and Study 2 (338 girls, 298 boys; 2nd – 6th grade; 7 – 11 years), children, parents, peers, and teachers reported on children’s externalizing behavior and internalizing symptoms, peer victimization, social alienation, and DPA. Path analyses supported the proposed pathway: Peer victimization predicted social alienation, which then predicted DPA. Early externalizing behavior set this path in motion and made an independent contribution to DPA. This research identifies an important pathway through which externalizing behavior and consequent peer victimization launch children onto a risky social trajectory. PMID:23621796

2012-06-01

The purpose of the present study was to compare children with a cochlear implant and normal hearing children on aspects of emotion regulation (emotion expression and coping strategies) and social functioning (social competence and externalizing behaviors) and the relation between emotion regulation and social functioning. Participants were 69 children with cochlear implants (CI children) and 67 normal hearing children (NH children) aged 1.5-5 years. Parents answered questionnaires about their children's language skills, social functioning, and emotion regulation. Children also completed simple tasks to measure their emotion regulation abilities. Cochlear implant children had fewer adequate emotion regulation strategies and were less socially competent than normal hearing children. The parents of cochlear implant children did not report fewer externalizing behaviors than those of normal hearing children. While social competence in normal hearing children was strongly related to emotion regulation, cochlear implant children regulated their emotions in ways that were unrelated with social competence. On the other hand, emotion regulation explained externalizing behaviors better in cochlear implant children than in normal hearing children. While better language skills were related to higher social competence in both groups, they were related to fewer externalizing behaviors only in cochlear implant children. Our results indicate that cochlear implant children have less adequate emotion-regulation strategies and less social competence than normal hearing children. Since they received their implants relatively recently, they might eventually catch up with their hearing peers. Longitudinal studies should further explore the development of emotion regulation and social functioning in cochlear implant children. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Dynamic response and transfer function of social systems: A neuro-inspired model of collective human activity patterns.

PubMed

Lymperopoulos, Ilias N

2017-10-01

The interaction of social networks with the external environment gives rise to non-stationary activity patterns reflecting the temporal structure and strength of exogenous influences that drive social dynamical processes far from an equilibrium state. Following a neuro-inspired approach, based on the dynamics of a passive neuronal membrane, and the firing rate dynamics of single neurons and neuronal populations, we build a state-of-the-art model of the collective social response to exogenous interventions. In this regard, we analyze online activity patterns with a view to determining the transfer function of social systems, that is, the dynamic relationship between external influences and the resulting activity. To this end, first we estimate the impulse response (Green's function) of collective activity, and then we show that the convolution of the impulse response with a time-varying external influence field accurately reproduces empirical activity patterns. To capture the dynamics of collective activity when the generating process is in a state of statistical equilibrium, we incorporate into the model a noisy input convolved with the impulse response function, thus precisely reproducing the fluctuations of stationary collective activity around a resting value. The outstanding goodness-of-fit of the model results to empirical observations, indicates that the model explains human activity patterns generated by time-dependent external influences in various socio-economic contexts. The proposed model can be used for inferring the temporal structure and strength of external influences, as well as the inertia of collective social activity. Furthermore, it can potentially predict social activity patterns. Copyright © 2017 Elsevier Ltd. All rights reserved.

Self-Determination and Meaningful Work: Exploring Socioeconomic Constraints.

Allan, Blake A; Autin, Kelsey L; Duffy, Ryan D

2016-01-01

This study examined a model of meaningful work among a diverse sample of working adults. From the perspectives of Self-Determination Theory and the Psychology of Working Framework, we tested a structural model with social class and work volition predicting SDT motivation variables, which in turn predicted meaningful work. Partially supporting hypotheses, work volition was positively related to internal regulation and negatively related to amotivation, whereas social class was positively related to external regulation and amotivation. In turn, internal regulation was positively related to meaningful work, whereas external regulation and amotivation were negatively related to meaningful work. Indirect effects from work volition to meaningful work via internal regulation and amotivation were significant, and indirect effects from social class to meaningful work via external regulation and amotivation were significant. This study highlights the important relations between SDT motivation variables and meaningful work, especially the large positive relation between internal regulation and meaningful work. However, results also reveal that work volition and social class may play critical roles in predicting internal regulation, external regulation, and amotivation.

Workplace Ostracism Seen through the Lens of Power

Fiset, John; Al Hajj, Raghid; Vongas, John G.

2017-01-01

Drawing on approach/inhibition theory of power, we investigated two factors that influence the manner by which victims react to workplace ostracism: the hierarchical status of the ostracizer and the level of an ostracizee’s external social support including family, friends, and significant others. Across an experimental vignette study (Study 1) and a field study (Study 2), we found support for a three-way interaction with felt ostracism, ostracizee external social support, and ostracizer status influencing victims’ organizational citizenship behavior and deviance directed toward other individuals. In addition, felt ostracism and ostracizee external social support interacted to predict turnover intentions. Overall, victims who were ostracized by a legitimate higher-status authority (e.g., manager) and whose external social support network was limited experienced the most negative outcomes across both studies. Our findings suggest that contextual factors both inside and outside the organization jointly impact the way in which individuals react to perceived workplace ostracism. Implications and future research directions are discussed. PMID:28928702

Antisocial Peer Affiliation and Externalizing Disorders in the Transition from Adolescence to Young Adulthood: Selection versus Socialization Effects

Prior research has demonstrated both socialization and selection effects for the relationship between antisocial peer affiliation and externalizing problems in adolescence. Less research has evaluated such effects post-adolescence. In this study, a cross-lagged panel analysis was used to evaluate the extent of socialization (i.e., the effect of antisocial peer affiliation on subsequent externalizing disorders) and selection (i.e., the effect of externalizing disorders on subsequent antisocial peer affiliation) in the prospective relationships between antisocial peer affiliation and externalizing disorders from adolescence through young adulthood. Data from a community sample of 2,769 individuals (52% female) with assessments at ages 17, 20, 24, and 29 were used. Analyses with a latent externalizing measure (estimated using clinical symptom counts of nicotine dependence, alcohol use disorder, illicit drug use disorder, and adult antisocial behavior) and self-reported antisocial peer affiliation revealed significantly stronger socialization effects from age 17 to 20, followed by significantly stronger selection effects from age 20 to 24 and 24 to 29. To better understand the impact of college experience, moderation by college status was evaluated at each developmental transition. Results were generally consistent for those who were in or were not in college. Results suggest selection effects are more important in later developmental periods than earlier periods, particularly in relation to an overall liability towards externalizing disorders, likely due to more freedom in peer selection post-adolescence.

Despite social marketing campaigns and behavior change interventions, young adults remain among the lowest consumers of vegetables. The digital era offers potential new avenues for both social marketing and individually tailored programs, through texting, web, and mobile applications. The effectiveness and generalizability of such programs have not been well documented. The aim of this systematic review is to evaluate the efficacy and external validity of social marketing, electronic, and mobile phone-based (mHealth) interventions aimed at increasing vegetable intake in young adults. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol will be used to conduct this systematic review. The search strategy will be executed across eleven electronic databases using combinations of the following search terms: "online intervention", "computer-assisted therapy", "internet", "website", "cell phones", "cyber", "telemedicine", "email", "social marketing", "social media", "mass media", "young adult", and "fruit and vegetables". The reference lists of included studies will also be searched for additional citations. Titles and abstracts will be screened against inclusion criteria and full texts of potentially eligible papers will be assessed by two independent reviewers. Data from eligible papers will be extracted. Quality and risk of bias will be assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies and The Cochrane Collaboration Risk of Bias assessment tool respectively. The external validity of the studies will be determined based on components such as reach, adoption, and representativeness of participants; intervention implementation and adaption; and program maintenance and institutionalization. Results will be reported quantitatively and qualitatively. Our research is in progress. A draft of the systematic review is currently being produced for publication by the end of 2015. The review findings will assist the design and implementation of future eHealth and mHealth programs aimed at improving vegetable consumption in young adults.

Many studies have focused on Type A and Type D personality types in the context of cardiovascular diseases (CVDs), but nothing is known about how these personality types combine to create new profiles. The present study aimed to develop a typology of Type A and Type D personality in two groups of patients affected by and at risk for coronary disease. The study involved 711 patients: 51.6% with acute coronary syndrome, 48.4% with essential hypertension (mean age = 56.4 years; SD = 9.7 years; 70.7% men). Cluster analysis was applied. External variables, such as socio-demographic, psychological, lifestyle, and clinical parameters, were assessed. Six groups, each with its own unique combined personality profile scores, were identified: Type D, Type A-Negatively Affected, Not Type A-Negatively Affected, Socially Inhibited-Positively Affected, Not Socially Inhibited, and Not Type A-Not Type D. The Type A-Negatively Affected cluster and, to a lesser extent, the Type D cluster, displayed the worst profile: namely higher total cardiovascular risk index, physical inactivity, higher anxiety and depression, and lower self-esteem, optimism, and health status. Identifying combined personality profiles is important in clinical research and practice in cardiovascular diseases. Practical implications are discussed. PMID:27589065

Philpott, Thomas G; Swettenham, Julie

2012-01-01

The complexity of governing has increased with the Internet's introduction of social media. Boards need to be aware of social media impact upon external stakeholder relations, as well as legal responsibilities within the organization. This paper outlines the various implications of social media that a board needs to consider. A governance framework is used to help put the issues in perspective. The conclusion is that boards need to take social media seriously and ensure that their organization has a social media risk mitigation strategy for external communications, as well as eDiscovery. Various other strategies and tactics are suggested to help boards address the challenge.

Adapting Social Neuroscience Measures for Schizophrenia Clinical Trials, Part 3: Fathoming External Validity

PubMed Central

Olbert, Charles M.

2013-01-01

It is unknown whether measures adapted from social neuroscience linked to specific neural systems will demonstrate relationships to external variables. Four paradigms adapted from social neuroscience were administered to 173 clinically stable outpatients with schizophrenia to determine their relationships to functionally meaningful variables and to investigate their incremental validity beyond standard measures of social and nonsocial cognition. The 4 paradigms included 2 that assess perception of nonverbal social and action cues (basic biological motion and emotion in biological motion) and 2 that involve higher level inferences about self and others’ mental states (self- referential memory and empathic accuracy). Overall, social neuroscience paradigms showed significant relationships to functional capacity but weak relationships to community functioning; the paradigms also showed weak correlations to clinical symptoms. Evidence for incremental validity beyond standard measures of social and nonsocial cognition was mixed with additional predictive power shown for functional capacity but not community functioning. Of the newly adapted paradigms, the empathic accuracy task had the broadest external validity. These results underscore the difficulty of translating developments from neuroscience into clinically useful tasks with functional significance. PMID:24072806

Physiological tibiofemoral kinematics have been shown to be important for good knee function after total knee arthroplasty (TKA). The purpose of the present study was to investigate the influence of component rotation on tibiofemoral kinematics during knee flexion. We asked which axial component alignment best reconstructs physiological tibiofemoral kinematics and which combinations should be avoided. Ten healthy cadaveric knees were examined. By means of a navigational device, tibiofemoral kinematics between 0° and 90° of flexion were assessed before and after TKA using the following different rotational component alignment: femoral components: ligament balanced, 6° internal, 3° external rotation, and 6° external rotation in relation to the posterior condylar line; tibial components: self-adapted, 6° internal rotation, and 6° external rotation. Physiological tibiofemoral kinematics could be partly reconstructed by TKA. Ligament-balanced femoral rotation and 6° femoral external rotation both in combination with 6° tibial component external rotation, and 3° femoral external rotation in combination with 6° tibial component internal rotation or self-aligning tibial component were able to restore tibial longitudinal rotation. Largest kinematical differences were found for the combination femoral component internal and tibial component external rotations. From a kinematic-based view, surgeons should avoid internal rotation of femoral components. However, even often recommended combinations of rotational component alignment (3° femoral external and tibial external rotation) significantly change tibiofemoral kinematics. Self-aligning tibial components solely restored tibiofemoral kinematics with the combination of 3° femoral component of external rotation. For the future, navigational devices might help to axially align components to restore patient-specific and natural tibiofemoral kinematics. Copyright © 2017 Elsevier Inc. All rights reserved.

To examine adoption of telehealth in a rural public health district and to explain how the innovation became sustainable. Longitudinal, qualitative study (1988-2008) of the largest public health district in Georgia. Case study design provided deep insights into the innovation's social dynamics. Punctuated equilibrium theory helped present and make sense of the process. We identified antecedent conditions and outcomes, and we distinguished between episodes and encounters based on the disruptive effects of events. Twenty-five semistructured interviews with 19 decision makers and professionals, direct observations, published papers, grant proposals, technical specifications, and other written materials. Strong collaboration within the district, with local community, and with external partners energized the process. Well-functioning outreach clinics made telehealth desirable. Local champions cultivated participation and generative capability, and overcame barriers through opportunistic exploitation of technological and financial options. Telehealth usage fluctuated between medical and administrative operations in response to internal needs and contextual dynamics. External agencies provided initial funding and supported later expansion.

Hofer, Claire; Eisenberg, Nancy; Reiser, Mark

2010-01-01

The relations among effortful control, ego resiliency, socialization, and social functioning were examined with a sample of 182 French adolescents (14–20 years old). Adolescents, their parents, and/or teachers completed questionnaires on these constructs. Effortful control and ego resiliency were correlated with adolescents’ social functioning, especially with low externalizing and internalizing behaviors and sometimes with high peer competence. Furthermore, aspects of socialization (parenting practices more than family expressiveness) were associated with adolescents’ effortful control, ego resiliency, and social functioning. Effortful control and ego resiliency mediated the relations between parental socialization and adolescents’ peer competence and internalizing problems. Furthermore, effortful control mediated the relations between socialization and adolescents’ externalizing behavior. Findings are discussed in terms of cultural and developmental variation.

Sandstrom, Marlene J; Cramer, Phebe

2003-08-01

The association between maturity of defense use and psychological functioning was assessed in a group of 95 elementary school children. Defense mechanisms were measured using a valid and reliable storytelling task, and psychological adjustment was assessed through a combination of parent and self-report questionnaires. Correlational analyses indicated that children who relied on the developmentally immature defense of denial reported higher levels of self-rated social anxiety and depression and received higher ratings of parent-reported internalizing and externalizing behavior problems. However, children who made use of the developmentally mature defense of identification exhibited higher scores on perceived competence in social, academic, conduct, athletic, and global domains. Significantly, there was no relationship between children's use of denial and their level of perceived competence or between children's use of identification and their degree of maladjustment.

Social Ontology Documentation for Knowledge Externalization

Aranda-Corral, Gonzalo A.; Borrego-Díaz, Joaquín; Jiménez-Mavillard, Antonio

Knowledge externalization and organization is a major challenge that companies must face. Also, they have to ask whether is possible to enhance its management. Mechanical processing of information represents a chance to carry out these tasks, as well as to turn intangible knowledge assets into real assets. Machine-readable knowledge provides a basis to enhance knowledge management. A promising approach is the empowering of Knowledge Externalization by the community (users, employees). In this paper, a social semantic tool (called OntoxicWiki) for enhancing the quality of knowledge is presented.

Social Networks and Externalities from Gift Exchange: Evidence from A Field Experiment☆

Currie, Janet; Lin, Wanchuan; Meng, Juanjuan

2016-01-01

This paper asks whether gift exchange generates externalities for people outside of the bilateral relationship between the gift giver and recipient, and whether the nature of this relationship is affected by social networks. We examine this question in the context of a field experiment in urban Chinese hospital outpatient clinics. We first show that when patients give a small gift, doctors reciprocate with better service and a fewer unnecessary prescriptions of antibiotics. We then show that gift giving creates externalities for third parties. If two patients, A and B are perceived as unrelated, B receives worse care when A gives a gift. However, if A identifies B as a friend, then both A and B benefit from A’s gift giving. Hence, we show that gift giving can create positive or negative externalities, depending on the giver’s social distance to the third party. PMID:26949272

Inducing Peer Pressure to Promote Cooperation

2013-01-01

Cooperation in a large society of self-interested individuals is notoriously difficult to achieve when the externality of one individual's action is spread thin and wide on the whole society. This leads to the ‘tragedy of the commons’ in which rational action will ultimately make everyone worse-off. Traditional policies to promote cooperation involve Pigouvian taxation or subsidies that make individuals internalize the externality they incur. We introduce a new approach to achieving global cooperation by localizing externalities to one's peers in a social network, thus leveraging the power of peer-pressure to regulate behavior. The mechanism relies on a joint model of externalities and peer-pressure. Surprisingly, this mechanism can require a lower budget to operate than the Pigouvian mechanism, even when accounting for the social cost of peer pressure. Even when the available budget is very low, the social mechanisms achieve greater improvement in the outcome. PMID:23619166

This study used a large (N = 519), longitudinal sample of adoptive families to test overreactive parenting as a mediator of associations between parental depressive symptoms and early childhood externalizing, and parents' social support satisfaction as a moderator. Maternal parenting (18 months) mediated the association between maternal depressive symptoms (9 months) and child externalizing problems (27 months). Paternal parenting was not a significant mediator. Unexpectedly, we found a cross-over effect for the moderating role of social support satisfaction, such that partners' social support satisfaction reduced the strength of the association between each parent's own depressive symptoms and overreactive parenting. Results point to the importance of accounting for broader family context in predicting early childhood parenting and child outcomes. © 2018 The Authors.

Self-Determination and Meaningful Work: Exploring Socioeconomic Constraints

Allan, Blake A.

2016-01-01

This study examined a model of meaningful work among a diverse sample of working adults. From the perspectives of Self-Determination Theory and the Psychology of Working Framework, we tested a structural model with social class and work volition predicting SDT motivation variables, which in turn predicted meaningful work. Partially supporting hypotheses, work volition was positively related to internal regulation and negatively related to amotivation, whereas social class was positively related to external regulation and amotivation. In turn, internal regulation was positively related to meaningful work, whereas external regulation and amotivation were negatively related to meaningful work. Indirect effects from work volition to meaningful work via internal regulation and amotivation were significant, and indirect effects from social class to meaningful work via external regulation and amotivation were significant. This study highlights the important relations between SDT motivation variables and meaningful work, especially the large positive relation between internal regulation and meaningful work. However, results also reveal that work volition and social class may play critical roles in predicting internal regulation, external regulation, and amotivation. PMID:26869970

In this work we focus on surfaces, which exhibit controlled, switchable wettability in response to one or more external stimuli as well as photocatalytic activity. For this we are inspired from nature to produce surfaces with a dual-scale hierarchical roughness and combine them with the appropriate inorganic and/or polymer coating. The combination of the hierarchical surface with a ZnO coating and a pH- or temperature-responsive polymer results in efficient photo-active properties as well as reversible superhydrophobic / superhydrophilic surfaces. Furthermore, we fabricate surfaces with unidirectional wettability variation. Overall, such complex surfaces require advanced design, combining hierarchically structured surfaces with suitable polymeric materials.

Facial expressions of emotion and psychopathology in adolescent boys.

PubMed

Keltner, D; Moffitt, T E; Stouthamer-Loeber, M

1995-11-01

On the basis of the widespread belief that emotions underpin psychological adjustment, the authors tested 3 predicted relations between externalizing problems and anger, internalizing problems and fear and sadness, and the absence of externalizing problems and social-moral emotion (embarrassment). Seventy adolescent boys were classified into 1 of 4 comparison groups on the basis of teacher reports using a behavior problem checklist: internalizers, externalizers, mixed (both internalizers and externalizers), and nondisordered boys. The authors coded the facial expressions of emotion shown by the boys during a structured social interaction. Results supported the 3 hypotheses: (a) Externalizing adolescents showed increased facial expressions of anger, (b) on 1 measure internalizing adolescents showed increased facial expressions of fear, and (c) the absence of externalizing problems (or nondisordered classification) was related to increased displays of embarrassment. Discussion focused on the relations of these findings to hypotheses concerning the role of impulse control in antisocial behavior.

Effects of post-weaning social isolation and environment al enrichment on exploratory behavior and ankiety in Wistar rats.

2015-01-01

Adverse early experience is generally regarded as a risk factor for both externalizing and internalizing behavioral disorders in humans. It can be modeled in rats by a post-weaning social isolation procedure. Effects of social isolation might possibly be ameliorated by environmental enrichment. In the current study, 24 male Wistar rats were divided post-weaning into four rearing conditions: control, environmental enrichment (EE), social isolation (SI) and a combination of the two experimental conditions; (EE+SI). Two observations of the effects of rearing conditions on the rate of social and object interactions were conducted during the juvenile and post-pubertal stages of development. The SI condition led to a marked increase of social interactions during the juvenile phase, but did not affect object interactions. The EE condition increased the level of social interactions during both the juvenile and post-pubertal measurements. The effects of early rearing conditions on adult exploratory behavior were less clear, with a significant difference between the groups obtained in one of three behavioral tests. Results suggest a general robustness in the development of adult exploratory behavior and anxiety when rats were exposed to early social isolation and provided brief opportunities for social play during the juvenile period. Further studies, aimed at distinguishing play-related protective factors serving against long-term adverse effects of juvenile social isolation, are suggested.

Social withdrawal in early childhood is a risk factor for later socioemotional difficulties. This study examined the joint effects of children's social withdrawal and mothers' and fathers' parenting styles on children's socioemotional development. Based on diatheses-stress, vantage sensitivity, and differential susceptibility models, socially withdrawn children were assumed to be more prone to parental influences than others. Teachers rated 314 children on prosocial skills, and internalizing and externalizing behaviors at three points in time between grades 1-3. Mothers (n = 279) and fathers (n = 182) filled in questionnaires measuring their affection, and their behavioral and psychological control at the same points in time. Teacher reports on children's level of social withdrawal were obtained at the end of kindergarten. Panel analysis showed that particularly those children who showed signs of social withdrawal were vulnerable to the negative effects of low maternal affection in terms of externalizing behavior. Moreover, among these children, mothers' and fathers' psychological control predicted high levels of internalizing problem but, at the same time, mothers' psychological control predicted also a high level of prosocial behavior and low levels of externalizing problem. The results supported the diathesis-stress model more than the differential susceptibility model. For example, socially withdrawn children were found to be particularly vulnerable to the negative effects of low maternal affection. Although maternal psychological control had positive effects on the prosocial skills of socially withdrawn children, and reduced the amount of externalizing problems, it was at the same time associated with an increase in their internalizing problems. In this way, socially withdrawn children seem to be at risk of pleasing their mothers at the cost of their own well-being. © 2014 The Authors.

External immunity in ant societies: sociality and colony size do not predict investment in antimicrobials

Social insects live in dense groups with a high probability of disease transmission and have therefore faced strong pressures to develop defences against pathogens. For this reason, social insects have been hypothesized to invest in antimicrobial secretions as a mechanism of external immunity to prevent the spread of disease. However, empirical studies linking the evolution of sociality with increased investment in antimicrobials have been relatively few. Here we quantify the strength of antimicrobial secretions among 20 ant species that cover a broad spectrum of ant diversity and colony sizes. We extracted external compounds from ant workers to test whether they inhibited the growth of the bacterium Staphylococcus epidermidis. Because all ant species are highly social, we predicted that all species would exhibit some antimicrobial activity and that species that form the largest colonies would exhibit the strongest antimicrobial response. Our comparative approach revealed that strong surface antimicrobials are common to particular ant clades, but 40% of species exhibited no antimicrobial activity at all. We also found no correlation between antimicrobial activity and colony size. Rather than relying on antimicrobial secretions as external immunity to control pathogen spread, many ant species have probably developed alternative strategies to defend against disease pressure.

2009-01-01

The purpose of this study was to explore the role of social preference and perceived acceptance as moderators of the relation between child temperament and externalizing behavior. Participants included 399 children evaluated at pre-kindergarten and kindergarten assessments. Pre-kindergarten children characterized by high temperamental Surgency/Extraversion were more likely to exhibit hyperactivity and aggression in the kindergarten classroom. In addition, kindergarten perceived acceptance and social preference moderated the relation between pre-kindergarten Surgency/Extraversion and kindergarten hyperactivity for girls only. Girls who were characterized by high temperamental Surgency/Extraversion, high perceived acceptance, and low social preference were at risk for higher levels of teacher-reported and peer-nominated hyperactivity. In contrast, accurately high perceived acceptance was a protective factor for high temperamental Surgency/Extraversion. Findings are discussed in terms of risk and protective factors for externalizing behavior. PMID:18605827

Respiratory Sinus Arrhythmia Activity Predicts Internalizing and Externalizing Behaviors in Non-referred Boys

Atypical respiratory sinus arrhythmia (RSA), a biomarker of emotion dysregulation, is associated with both externalizing and internalizing behaviors. In addition, social adversity and gender may moderate this association. In this study, we investigated if RSA (both resting RSA and RSA reactivity in an emotion regulation task) predicts externalizing and/or internalizing behaviors and the extent to which social adversity moderates this relationship. Two hundred and fifty-three children (at Time 1, mean age = 9.05, SD = 0.60, 48% boys) and their caregivers from the community participated in this study. Resting RSA and RSA reactivity were assessed, and caregivers reported children’s externalizing and internalizing behaviors at both Time 1 and Time 2 (1 year later). We found that lower resting RSA (but not RSA reactivity) at Time 1 was associated with increased externalizing and internalizing behaviors at Time 2 in boys, even after controlling for the effects of Time 1 behavioral problems and Time 2 age. Moreover, there was a significant interaction effect between Time 1 resting RSA and social adversity such that lower resting RSA predicted higher externalizing and internalizing behaviors in boys only under conditions of high social adversity. Follow-up analyses revealed that these predictive effects were stronger for externalizing behavior than for internalizing behavior. No significant effects were found for girls. Our findings provide further evidence that low resting RSA may be a transdiagnostic biomarker of emotion dysregulation and a predisposing risk factor for both types of behavior problems, in particular for boys who grow up in adverse environments. We conclude that biosocial interaction effects and gender differences should be considered when examining the etiological mechanisms of child psychopathology. PMID:28955262

Students who do not get along with their peers are at elevated risk for academic disengagement and school failure. Research has predominantly focused on factors within such children that contribute to their peer problems. This study considers whether teacher practices also predict social preference for children in that classroom. Participants were 26 elementary school teachers and 490 students in their classrooms followed for one school year. Results suggested that teachers who favored the most academically talented students in the fall had classrooms where children had lower average social preference in the spring after statistical control of children's fall social preference and externalizing behavior problems. Teachers who demonstrated emotionally supportive relationships with students in the fall had classrooms where children had greater possibility of changing their social preference from fall to spring. Although children with high externalizing behaviors tended to experience declining social preference over the course of the school year, teachers' learner-centered practices attenuated this progression. However, teachers' favoring of the most academically talented accentuated the negative relation between externalizing behaviors and social preference. Implications for school psychology practitioners are discussed. Copyright © 2011 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

The development of technological applications that allow people to control and embody external devices within social interaction settings represents a major goal for current and future brain-computer interface (BCI) systems. Prior research has suggested that embodied systems may ameliorate BCI end-user's experience and accuracy in controlling external devices. Along these lines, we developed an immersive P300-based BCI application with a head-mounted display for virtual-local and robotic-remote social interactions and explored in a group of healthy participants the role of proprioceptive feedback in the control of a virtual surrogate (Study 1). Moreover, we compared the performance of a small group of people with spinal cord injury (SCI) to a control group of healthy subjects during virtual and robotic social interactions (Study 2), where both groups received a proprioceptive stimulation. Our attempt to combine immersive environments, BCI technologies and neuroscience of body ownership suggests that providing realistic multisensory feedback still represents a challenge. Results have shown that healthy and people living with SCI used the BCI within the immersive scenarios with good levels of performance (as indexed by task accuracy, optimizations calls and Information Transfer Rate) and perceived control of the surrogates. Proprioceptive feedback did not contribute to alter performance measures and body ownership sensations. Further studies are necessary to test whether sensorimotor experience represents an opportunity to improve the use of future embodied BCI applications.

Codevelopment of externalizing and internalizing symptoms in middle to late childhood: Sex, baseline respiratory sinus arrhythmia, and respiratory sinus arrhythmia reactivity as predictors

2013-01-01

We investigated the roles of sex and respiratory sinus arrhythmia (RSA), an index of autonomic parasympathetic nervous system activity, as predictors of codeveloping externalizing and internalizing symptoms in middle childhood. We expected that sex, baseline RSA (RSA-B), and RSA reactivity (RSA-R) to two types of tasks would interact to differentiate co-occurring trajectories of symptoms. We tested these hypotheses by combining longitudinal data from two independent samples (n = 390; 210 girls, 180 boys) with repeated measures at ages 8, 9, 10, and 11. RSA-R was measured in response to a socially stressful and frustrating stressor. Indicators of growth in externalizing and internalizing symptoms were derived from multiple domain growth models and used in person-centered growth mixture analyses. Three groups of externalizing and internalizing trajectories were found. Profile membership was predicted by several two-way interactions among sex, RSA-B, or RSA-R but was not predicted by three-way interactions. Children with low RSA-B and strong RSA withdrawal, girls with low RSA-B, and girls with strong RSA withdrawal were more likely to be on a developmental trajectory of low externalizing symptoms and moderately elevated internalizing symptoms. Membership in the high externalizing and high internalizing trajectory was predicted by weak RSA withdrawal for boys and strong RSA withdrawal for girls. The type of stressor task also played a role in predicting probability of profile membership. Results are discussed in the context of developmental psychobiology and implications for the codevelopment of psychopathology symptoms in childhood. PMID:23627954

Increasing social welfare by taxing pesticide externalities in the Indian cotton sector.

Pesticide use in the Indian cotton industry has decreased with the introduction of Bt cotton, but rates are still high in comparison with other countries. The adoption of alternative strategies, such as integrated pest management, has been slow, even though benefits are potentially high, more so if the full costs of the external effects of the technologies are taken into account. In order to estimate true societal benefits of different strategies, we compare their external costs and economic performance under external cost taxation, using a state-of-the-art partial equilibrium model of the Indian agricultural sector. Pesticide externalities lower social welfare in the Indian cotton sector by $US 400-2200 million, depending on the technologies employed. A full internalisation reduces producer revenues by $US 100 ha -1 if only Bt cotton is used, and by $US 30 ha -1 if IPM is another option. Consumers do not start to lose surplus until 20-70% are internalised, and losses are smaller if all technologies are available. External pesticide costs can be internalised partially without substantially affecting consumer surplus while still increasing social welfare, but producers need to have access to and the knowledge to employ all available cotton production technologies to minimise losses. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Smoker Identity Development among Adolescents who Smoke

Adolescents who smoke are more likely to escalate their smoking frequency if they believe smoking is self-defining. Knowing factors that are associated with development of a smoker identity among adolescents who smoke may help to identify who will become a regular smoker. We investigated whether smoker identity development is associated with internal and external motives for smoking. For comparison, we also investigated whether social smoker identity development is associated with internal and external motives for smoking. Adolescents who smoke (n = 292) completed measures of smoker and social smoker identity, internal motives for smoking (negative affect coping, positive affect enhancement), and external motives for smoking (social fit) at baseline, 6-, 15-, and 24-month assessments of an ongoing longitudinal study of smoking patterns. We examined whether change in smoker and social smoker identity from 6 to 24 months was associated with change in motives at earlier assessment waves. We also explored whether gender moderated these relationships. Increases in negative affect coping motives were associated with smoker identity development among both males and females. Increases in social motives were associated with smoker identity development among males, and increases in negative affect coping motives were associated with social smoker identity development among females. Smoker and social smoker identities are signaled by negative affect coping as well as social motives for smoking. PMID:27136374

2012-01-01

The extent to which peer influences on substance use in adolescence systematically vary in strength based on qualities of the adolescent and his or her close friend was assessed in a study of 157 adolescents (Age: M = 13.35, SD = 0.64), their close friends and their parents assessed longitudinally with a combination of observational, analogue, sociometric, and self-report measures from early to mid-adolescence. The degree to which adolescents changed their levels of substance use in accord with their peers' baseline levels of use was predicted by a range of theoretically-salient factors including: observed teen lack of autonomy and social support in prior interactions with mothers, low teen refusal skills, and the level of social acceptance of their close friend. Findings suggest the importance of both internal factors (e.g., autonomy and relatedness struggles) and external factors (e.g., social status of friends) in explaining why vulnerability to peer influence processes may be much greater for some adolescents than others.

Risk communication and human biomonitoring: which practical lessons from the Belgian experience are of use for the EU perspective?

PubMed Central

Keune, Hans; Morrens, Bert; Loots, Ilse

2008-01-01

Background In order to investigate and monitor environmental health in Flanders (the Dutch speaking part of Belgium), the Flemish government funded the Centre of Expertise for Environment and Health, which started a human biomonitoring campaign in 2001. In addition to environmental health experts measuring environmental pollutants and health effects in human beings, social scientific experts at the Centre focus on risk communication associated with the human biomonitoring campaign. Methods In the literature about risk communication an evolution can be traced from traditional, one-way communication, restricted to the dissemination of information from experts to the public, to more modern, two-way risk communication, with a focus on participation and cooperation between scientists, policy-makers and the public. Within the Centre of Expertise for Environment and Health this discourse was first translated into some general principles and guidelines for external communication, at a 'Ten Commandments level'. These principles needed to be incorporated in the day-to-day practice of human biomonitoring research. Results The social scientific experts at the Centre developed a combined risk communication strategy. On the one hand the strategy consists of traditional risk communication for external communication purposes, for example information meetings and digital newsletters. On the other hand it consists of a step by step approach of incorporating more modern risk communication, for example a risk perception questionnaire, dialogical experiments for involving local stakeholders, and an action-plan for interpreting results for policy making. Conclusion With a parallel strategy of traditional and modern communication, of external and internal reflection, and through different social scientific projects, the Flemish Centre of Expertise of Environment and Health incorporates risk communication in the day-to-day practice of human biomonitoring research. A direct and continuous involvement of the social scientist, an openness between all colleagues involved, and the awareness of a fine balance between quality and practicability are important success factors. These lessons may be helpful and inspirational for a European human biomonitoring project. PMID:18541065

Neighborhood characteristics have been shown to impact child well-being. However, it remains unclear how these factors combine with family characteristics to influence child development. The current study helps develop that understanding by investigating how neighborhoods directly impact child and adolescent behavior problems as well as moderate the influence of family characteristics on behavior. Using multilevel linear models, we examined the relationship among neighborhood conditions (poverty and social capital) and maternal depression on child and adolescent behavior problems. The sample included 741 children, age 5–11, and 564 adolescents, age 12–17. Outcomes were internalizing (e.g. anxious/depressed) and externalizing (e.g. aggressive/hyperactive) behavior problems. Neighborhood poverty and maternal depression were both positively associated with behavior problems for children and adolescents. However, while neighborhood social capital was not directly associated with behavior problems, the interaction of social capital and maternal depression was significantly related to behavior problems for adolescents. This interaction showed that living in neighborhoods with higher levels of social capital attenuated the relationship between maternal depression and adolescent behavior problems and confirmed the expectation that raising healthy well-adjusted children depends not only on the family, but also the context in which the family lives.

Prior research suggests that heightened emotional reactivity to emotionally distressing stimuli may be associated with elevated internalizing and externalizing behaviors, and contribute to impaired social functioning. These links were explored in a sample of 169 economically-disadvantaged kindergarteners (66 % male; 68 % African American, 22 % Hispanic, 10 % Caucasian) oversampled for elevated aggression. Physiological measures of emotional reactivity (respiratory sinus arrhythmia [RSA], heart rate [HR], and cardiac pre-ejection period [PEP]) were collected, and teachers and peers provided ratings of externalizing and internalizing behavior, prosocial competence, and peer rejection. RSA withdrawal, HR reactivity, and PEP shortening (indicating increased arousal) were correlated with reduced prosocial competence, and RSA withdrawal and HR reactivity were correlated with elevated internalizing problems. HR reactivity was also correlated with elevated externalizing problems and peer rejection. Linear regressions controlling for age, sex, race, verbal proficiency, and resting physiology showed that HR reactivity explained unique variance in both teacher-rated prosocial competence and peer rejection, and contributed indirectly to these outcomes through pathways mediated by internalizing and externalizing problems. A trend also emerged for the unique contribution of PEP reactivity to peer-rated prosocial competence. These findings support the contribution of emotional reactivity to behavior problems and social adjustment among children living in disadvantaged urban contexts, and further suggest that elevated reactivity may confer risk for social difficulties in ways that overlap only partially with internalizing and externalizing behavior problems.

Relationships between internal-external control and romantic love were hypothesized on the basis of a social influence interpretation and the view that romantic love is culturally stereotyped as an external force. Consistent with these perspectives, proportionally fewer internals than externals reported having been romantically attached. (Author)

The External Performance Appraisal of China Energy Regulation: An Empirical Study Using a TOPSIS Method Based on Entropy Weight and Mahalanobis Distance.

In China's industrialization process, the effective regulation of energy and environment can promote the positive externality of energy consumption while reducing negative externality, which is an important means for realizing the sustainable development of an economic society. The study puts forward an improved technique for order preference by similarity to an ideal solution based on entropy weight and Mahalanobis distance (briefly referred as E-M-TOPSIS). The performance of the approach was verified to be satisfactory. By separately using traditional and improved TOPSIS methods, the study carried out the empirical appraisals on the external performance of China's energy regulation during 1999~2015. The results show that the correlation between the performance indexes causes the significant difference between the appraisal results of E-M-TOPSIS and traditional TOPSIS. The E-M-TOPSIS takes the correlation between indexes into account and generally softens the closeness degree compared with traditional TOPSIS. Moreover, it makes the relative closeness degree fluctuate within a small-amplitude. The results conform to the practical condition of China's energy regulation and therefore the E-M-TOPSIS is favorably applicable for the external performance appraisal of energy regulation. Additionally, the external economic performance and social responsibility performance (including environmental and energy safety performances) based on the E-M-TOPSIS exhibit significantly different fluctuation trends. The external economic performance dramatically fluctuates with a larger fluctuation amplitude, while the social responsibility performance exhibits a relatively stable interval fluctuation. This indicates that compared to the social responsibility performance, the fluctuation of external economic performance is more sensitive to energy regulation.

Heart rate variability indicates emotional value during pro-social economic laboratory decisions with large external validity.

PubMed

Fooken, Jonas

2017-03-10

The present study investigates the external validity of emotional value measured in economic laboratory experiments by using a physiological indicator of stress, heart rate variability (HRV). While there is ample evidence supporting the external validity of economic experiments, there is little evidence comparing the magnitude of internal levels of emotional stress during decision making with external stress. The current study addresses this gap by comparing the magnitudes of decision stress experienced in the laboratory with the stress from outside the laboratory. To quantify a large change in HRV, measures observed in the laboratory during decision-making are compared to the difference between HRV during a university exam and other mental activity for the same individuals in and outside of the laboratory. The results outside the laboratory inform about the relevance of laboratory findings in terms of their relative magnitude. Results show that psychologically induced HRV changes observed in the laboratory, particularly in connection with social preferences, correspond to large effects outside. This underscores the external validity of laboratory findings and shows the magnitude of emotional value connected to pro-social economic decisions in the laboratory.

Social desirability response tendencies in psychiatric inpatient children.

PubMed

Mabe, P A; Treiber, F A

1989-03-01

This study examined the substantive features of children's social desirability (SD) tendencies that could influence the nature and severity of psychopathology. Examinations of substantive features of SD responding in an inpatient child psychiatry unit (N = 76) suggested that higher scores on the Children's Social Desirability questionnaire were associated strongly with (1) lower mental age; (2) higher scores on self-reported social competence; (3) lower scores on self-reported anger; and (4) lower scores on parent-reported externalization behavioral disturbance. Results were interpreted as suggesting that SD responding for child inpatients may reflect a mixed picture of negative features of cognitive and social immaturity that could affect adversely their ability to judge their own and others' social behavior and of positive features of less external behavioral disturbance and more prosocial attitudes and behaviors.

Objective To examine adoption of telehealth in a rural public health district and to explain how the innovation became sustainable. Study Setting Longitudinal, qualitative study (1988–2008) of the largest public health district in Georgia. Study Design Case study design provided deep insights into the innovation's social dynamics. Punctuated equilibrium theory helped present and make sense of the process. We identified antecedent conditions and outcomes, and we distinguished between episodes and encounters based on the disruptive effects of events. Data Collection Twenty-five semistructured interviews with 19 decision makers and professionals, direct observations, published papers, grant proposals, technical specifications, and other written materials. Principal Findings Strong collaboration within the district, with local community, and with external partners energized the process. Well-functioning outreach clinics made telehealth desirable. Local champions cultivated participation and generative capability, and overcame barriers through opportunistic exploitation of technological and financial options. Telehealth usage fluctuated between medical and administrative operations in response to internal needs and contextual dynamics. External agencies provided initial funding and supported later expansion. Conclusions Extensive internal and external collaboration, and a combination of technology push and opportunistic exploitation, can enable sustainable rural telehealth innovation. PMID:20459449

A Self-Regulatory Model of Behavioral Disinhibition in Late Adolescence: Integrating Personality Traits, Externalizing Psychopathology, and Cognitive Capacity

PubMed Central

Bogg, Tim; Finn, Peter R.

2011-01-01

Two samples with heterogeneous prevalence of externalizing psychopathology were used to investigate the structure of self-regulatory models of behavioral disinhibition and cognitive capacity. Consistent with expectations, structural equation modeling in the first sample (N = 541) showed a hierarchical model with three lower-order factors of impulsive sensation-seeking, anti-sociality/unconventionality, and lifetime externalizing problem counts, with a behavioral disinhibition superfactor best accounted for the pattern of covariation among six disinhibited personality trait indicators and four externalizing problem indicators. The structure was replicated in a second sample (N = 463) and showed that the behavioral disinhibition superfactor, and not the lower-order impulsive sensation-seeking, anti-sociality/unconventionality, and externalizing problem factors, was associated with lower IQ, reduced short-term memory capacity, and reduced working memory capacity. The results provide a systemic and meaningful integration of major self-regulatory influences during a developmentally important stage of life. PMID:20433626

The dorsal striatum and ventral striatum play different roles in the programming of social behaviour: a tribute to Lex Cools.

PubMed

van den Bos, Ruud

2015-02-01

Early work by Lex Cools suggested that the caudate nucleus (dorsal striatum) plays a role in programming social behaviour: enhanced activity in the caudate nucleus increased the extent to which ongoing behaviour is controlled by the individual's own behaviour (internal control) rather than by that of its partners (external control). Interestingly, later studies by others have indicated that the ventral striatum plays a role in external rather than internal control. Here, I discuss the role of these different striatal areas - and the emotional (ventral striatum) and cognitive control (dorsal striatum) system in which they are embedded - in the organization of social behaviour in the context of locus of control. Following on from this discussion, I will pay particular attention to individual differences in social behaviour (individuals with more internal or external control), focusing on the role of dopamine, serotonin and the effects of stress-related challenges in relation to their different position in a dominance hierarchy. I will subsequently allude to potential psychological and behavioural problems in the social domain following on from these differences in locus of control ['social obliviousness' (dorsal stratum) and 'social impulsivity' (ventral striatum)]. In doing so, I provide as a tribute a historical account of the early research by Lex Cools.

Early Adolescent Friendship Selection Based on Externalizing Behavior: the Moderating Role of Pubertal Development. The SNARE Study.

2016-11-01

This study examined friendship (de-)selection processes in early adolescence. Pubertal development was examined as a potential moderator. It was expected that pubertal development would be associated with an increased tendency for adolescents to select their friends based on their similarities in externalizing behavior engagement (i.e., delinquency, alcohol use, and tobacco use). Data were used from the first three waves of the SNARE (Social Network Analysis of Risk behavior in Early adolescence) study (N = 1144; 50 % boys; M age  = 12.7; SD = 0.47), including students who entered the first year of secondary school. The hypothesis was tested using Stochastic Actor-Based Modeling in SIENA. While taking the network structure into account, and controlling for peer influence effects, the results supported this hypothesis. Early adolescents with higher pubertal development were as likely as their peers to select friends based on similarity in externalizing behavior and especially likely to remain friends with peers who had a similar level of externalizing behavior, and thus break friendship ties with dissimilar friends in this respect. As early adolescents are actively engaged in reorganizing their social context, adolescents with a higher pubertal development are especially likely to lose friendships with peers who do not engage in externalizing behavior, thus losing an important source of adaptive social control (i.e., friends who do not engage in externalizing behavior).

Procedures involving needles are the most common and major sources of pain in children. External cold and vibration via Buzzy (MMJ Labs, Atlanta, GA) is a method that combines cooling and vibration. This study investigated the effect of the combined stimulation of skin with external cold and vibration via Buzzy on the pain and anxiety levels in children during immunization. This study was a prospective, randomized controlled trial. Children were randomized into two groups: experimental (external cold and Buzzy) and control (no intervention). The pain and anxiety levels of the children were assessed using the Wong-Baker FACES scale and Children Fear Scale. The experimental group showed significantly lower pain and anxiety levels than the control group during immunization. The combined stimulation of skin with external cold and vibration can be used to reduce pain and anxiety during pediatric immunization. Copyright © 2015 American Society of PeriAnesthesia Nurses.

2014-02-01

The current study examined how parental ethnic socialization informed adolescents' ethnic identity development and, in turn, youths' psychosocial functioning (i.e., mental health, social competence, academic efficacy, externalizing behaviors) among 749 Mexican-origin families. In addition, school ethnic composition was examined as a moderator of these associations. Findings indicated that mothers' and fathers' ethnic socialization were significant longitudinal predictors of adolescents' ethnic identity, although fathers' ethnic socialization interacted significantly with youths' school ethnic composition in 5 th grade to influence ethnic identity in 7 th grade. Furthermore, adolescents' ethnic identity was significantly associated with increased academic self-efficacy and social competence, and decreased depressive symptoms and externalizing behaviors. Findings support theoretical predictions regarding the central role parents play in Mexican-origin adolescents' normative developmental processes and adjustment and, importantly, underscore the need to consider variability that is introduced into these processes by features of the social context such as school ethnic composition.

Experimental manipulation of avian social structure reveals segregation is carried over across contexts

PubMed Central

Firth, Josh A.; Sheldon, Ben C.

2015-01-01

Our current understanding of animal social networks is largely based on observations or experiments that do not directly manipulate associations between individuals. Consequently, evidence relating to the causal processes underlying such networks is limited. By imposing specified rules controlling individual access to feeding stations, we directly manipulated the foraging social network of a wild bird community, thus demonstrating how external factors can shape social structure. We show that experimentally imposed constraints were carried over into patterns of association at unrestricted, ephemeral food patches, as well as at nesting sites during breeding territory prospecting. Hence, different social contexts can be causally linked, and constraints at one level may have consequences that extend into other aspects of sociality. Finally, the imposed assortment was lost following the cessation of the experimental manipulation, indicating the potential for previously perturbed social networks of wild animals to recover from segregation driven by external constraints.

Social dilemma in the external immune system of the red flour beetle? It is a matter of time.

PubMed

Gokhale, Chaitanya S; Traulsen, Arne; Joop, Gerrit

2017-09-01

Sociobiology has revolutionized our understanding of interactions between organisms. Interactions may present a social dilemma where the interests of individual actors do not align with those of the group as a whole. Viewed through a sociobiological lens, nearly all interactions can be described regarding their costs and benefits, and a number of them then resemble a social dilemma. Numerous experimental systems, from bacteria to mammals, have been proposed as models for studying such dilemmas. Here, we make use of the external immune system of the red flour beetle, Tribolium castaneum , to investigate how the experimental duration can affect whether the external secretion comprises a social dilemma or not. Some beetles (secretors) produce a costly quinone-rich external secretion that inhibits microbial growth in the surrounding environment, providing the secretors with direct personal benefits. However, as the antimicrobial secretion acts in the environment of the beetle, it is potentially also advantageous to other beetles (nonsecretors), who avoid the cost of producing the secretion. We test experimentally if the secretion qualifies as a public good. We find that in the short term, costly quinone secretion can be interpreted as a public good presenting a social dilemma where the presence of secretors increases the fitness of the group. In the long run, the benefit to the group of having more secretors vanishes and becomes detrimental to the group. Therefore, in such seminatural environmental conditions, it turns out that qualifying a trait as social can be a matter of timing.

This paper analyses the role of local social, cultural, and political institutions in post-disaster reconstruction projects. It contends that such institutions are important considerations within community-driven reconstruction initiatives, but are often viewed with ambivalence by external aid organisations. This paper draws upon in-depth qualitative interviews with aid workers involved in the post-tsunami reconstruction in Aceh, Indonesia, to establish: (i) what roles community institutions were suited to play in the reconstruction; (ii) what were the limitations of community institutions when engaging with external aid agencies; (iii) how did external aid agencies engage with local community institutions; and (iv) how did external aid agencies perceive community institutions. © 2015 The Author(s).

Previous research has found a strong correlation between children's academic self-concept and their behavioral problems. The present study examined whether children's peer rejection moderated the relationship between children's math and verbal self-concepts and their behavioral problems at school. We expected that children's social competence, as measured by peer rejection, moderated the negative effect of low self-concept on children's externalizing behaviors. Participants were 173 children (males = 93, M age = 10.31 years, SD = 1.43). The main findings showed that peer rejection moderated the effect of both low verbal and math self-concepts on children's externalizing behavior. The results are discussed in terms of the protective factor played by children's social competence reducing the impact of low self-concept on children's externalizing behaviors.

Specificity of relations between children's control-related beliefs and internalizing and externalizing psychopathology.

The authors examined the specificity of the relation between 3 types of control-related beliefs and internalizing and externalizing psychopathology in a sample of 290 clinic-referred children aged 7 to 17 years. Self-reported beliefs about control (the capacity to cause an intended outcome), contingency (the degree to which a desired outcome can be controlled by a relevant behavior), and competence (an individual's ability to produce the relevant behavior) across 3 domains (academic, behavioral, and social) showed more specific relations with psychopathology than have been previously reported. Among children with externalizing psychopathology, internalizing psychopathology may be specifically associated with increased self-critical awareness about their conduct; externalizing psychopathology may attenuate the specific negative relation between internalizing psychopathology and control-related beliefs in the social domain.

Social media are increasingly being used for educational purposes. The first part of this article briefly reviews literature that reports on educational applications of social media tools. The second part discusses theories that may provide a basis for analyzing the processes that are relevant for individual learning and collective knowledge construction. We argue that a systems-theoretical constructivist approach is appropriate to examine the processes of educational social media use, namely, self-organization, the internalization of information, the externalization of knowledge, and the interplay of externalization and internalization providing the basis of a co-evolution of cognitive and social systems. In the third part we present research findings that illustrate and support this systems-theoretical framework. Concluding, we discuss the implications for educational design and for future research on learning and collective knowledge construction with social media. PMID:26246643

This study compared the efficacy between external fixator combined with palmar T-plate internal fixation and simple plate internal fixation for the treatment of comminuted distal radius fractures. A total of 61 patients classified as type C according to the AO/ASIF classification underwent surgery for comminuted distal radius fractures. There were 54 and 7 cases of closed and open fractures, respectively. Moreover, 19 patients received an external fixator combined with T-plate internal fixation, and 42 received simple plate internal fixation. All patients were treated successfully during 12-month postoperative follow-up. The follow-up results show that the palmar flexion and dorsiflexion of the wrist, radial height, and palmar angle were significantly better in those treated with the external fixator combined with T-plate compared to those treated with the simple plate only (P < 0.05); however, there were no significant differences in radial-ulnar deviation, wrist range of motion, or wrist function score between groups (P > 0.05). Hence, the effectiveness of external fixator combined with T-plate internal fixation for the treatment of comminuted distal radius fractures was satisfactory. Patients sufficiently recovered wrist, forearm, and hand function. In conclusion, compared to the simple T-plate, the external fixator combined with T-plate internal fixation can reduce the possibility of the postoperative re-shifting of broken bones and keep the distraction of fractures to maintain radial height and prevent radial shortening.

Towards Humanlike Social Touch for Prosthetics and Sociable Robotics: Three-Dimensional Finite Element Simulations of Synthetic Finger Phalanges

NASA Astrophysics Data System (ADS)

Cabibihan, John-John; Ge, Shuzhi Sam

Synthetic skins with humanlike characteristic would make it possible to address some of the psychosocial requirements of prosthetic hands as well as the safety and acceptance issues in social robotics. This paper describes the development of three-dimensional finite element models of synthetic finger phalanges. With the aim of duplicating the skin compliance of human finger phalanges, the model was used to investigate the effects of (i) introducing open pockets in the internal structure and (ii) combining different materials as external and internal layers. The results show that having pockets in the internal structure of the design can increase the skin compliance of the synthetic phalanges and make it comparable with the human counterpart. Moreover, having different layers can be used to satisfy skin compliance and other design requirements such as wear and tear.

Parent emotion socialization plays an important role in shaping emotional and behavioral development during adolescence. The Tuning in to Teens (TINT) program aims to improve parents' responses to young people's emotions with a focus on teaching emotion coaching. This study examined the efficacy of the TINT program in improving emotion socialization practices in parents and whether this reduced family conflict and youth externalizing difficulties. Schools were randomized into intervention and control conditions and 225 primary caregiving parents and 224 youth took part in the study. Self-report data was collected from parents and youth during the young person's final year of elementary school and again in their first year of secondary school. Multilevel analyses showed significant improvements in parent's impulse control difficulties and emotion socialization, as well as significant reductions in family conflict and youth externalizing difficulties. This study provides support for the TINT program in reducing youth externalizing behavior problems. Copyright © 2015 The Foundation for Professionals in Services for Adolescents.

The current study investigated concurrent and longitudinal mediated and mediated moderation pathways among maltreatment, self-perception (i.e., loneliness and self-esteem), social support, and internalizing and externalizing behavior problems. For both genders, early childhood maltreatment (i.e., ages 0-6) was related directly to internalizing and externalizing behavior problems at age 6, and later maltreatment (i.e., ages 6-8) was directly related to internalizing and externalizing behavior problems at age 8. Results of concurrent mediation and mediated moderation indicated that early maltreatment was significantly related to internalizing and externalizing behavior problems at age 6 indirectly both through age 6 loneliness and self-esteem for boys and through age 6 loneliness for girls. Significant moderation of the pathway from early maltreatment to self-esteem, and for boys, significant mediated moderation to emotional and behavioral problems were found, such that the mediated effect through self-esteem varied across levels of social support, though in an unexpected direction. No significant longitudinal mediation or mediated moderation was found, however, between the age 6 mediators and moderator and internalizing or externalizing problems at age 8. The roles of the hypothesized mediating and moderating mechanisms are discussed, with implications for designing intervention and prevention programs.

Other changes result from external trends such as emerging foreign competition. These circumstances intensify the need to understand the production, transfer, and utilization of knowledge as a precursor to the rapid diffusion of technology. This article presents a conceptual framework for understanding the diffusion of aerospace knowledge. The framework focuses on the information channels and members of the social system associated with the aerospace knowledge diffusion process, placing particular emphasis on aerospace librarians as information intermediaries.

In this paper, we examine common methods for using individual-level data to represent classroom composition by examining exemplary studies that thoughtfully incorporate such measures. Building on these studies, and using data from the Chicago School Readiness Project (CSRP), this paper examines theoretical and analytical implications of a set of different transformations of individual ratings of child externalizing behaviors in order to examine and compare the influence of these representations of classroom composition on Kindergarten internalizing behaviors, social competence, and attention/impulsivity problems. Results indicate that each Kindergarten outcome is influenced by distinct aspects of classroom composition of externalizing behaviors. Kindergarten internalizing behaviors are positively associated with the proportion of children in the Head Start classroom who started with externalizing scores above the 75th percentile regardless of the average value of externalizing behaviors in the classroom. In contrast, Kindergarten social competence is predicted by three aspects of the classroom distribution of externalizing behaviors in the fall of Head Start—the classroom mean, standard deviation, and skew. Finally, Kindergarten attention/impulsivity problems were not associated with any aspect of classroom composition of externalizing behavior examined in this paper. PMID:28275289

This study explored responsibility attribution (RA) of HIV/AIDS infection (i.e., how an individual perceives the cause of their HIV/AIDS infection) and its relationship to coping styles among injection drug users (IDUs) with HIV/AIDS. In addition, this study investigated whether self-esteem, social support, and religiosity mediate the relationship between RA and coping styles of IDUs with HIV/AIDS. Participants were 201 adult IDUs with HIV/AIDS participating in the National Drug Rehabilitation Center in Malaysia. Five measures were used to assess the above constructs. Cluster analysis, analysis of variance, and mediation analyses were conducted. Results of this study indicated that IDUs with HIV/AIDS in Malaysia can be classified into four homogenous attribution groups: external, fatalistic, internal, and indeterminate. Mediator analyses revealed that combination of self-esteem, social support, and religiosity mediate the relationship between RA and coping behaviors. Clinicians working with IDUs with HIV/AIDS need to address the role of RA, self-esteem, religiosity, and social support as these psychosocial constructs are linked to coping with HIV/AIDS. Future researchers should investigate whether enhancing self-esteem, social support, and religiosity can promote active problem-solving coping and reduce the use of avoidance coping behaviors.

Events in an online social network can be categorized roughly into endogenous events, where users just respond to the actions of their neighbors within the network, or exogenous events, where users take actions due to drives external to the network. How much external drive should be provided to each user, such that the network activity can be steered towards a target state? In this paper, we model social events using multivariate Hawkes processes, which can capture both endogenous and exogenous event intensities, and derive a time dependent linear relation between the intensity of exogenous events and the overall network activity. Exploiting this connection, we develop a convex optimization framework for determining the required level of external drive in order for the network to reach a desired activity level. We experimented with event data gathered from Twitter, and show that our method can steer the activity of the network more accurately than alternatives. PMID:26005312

Does Neighborhood Social Capital Buffer the Effects of Maternal Depression on Adolescent Behavior Problems?

Neighborhood characteristics have been shown to impact child well-being. However, it remains unclear how these factors combine with family characteristics to influence child development. The current study helps develop that understanding by investigating how neighborhoods directly impact child and adolescent behavior problems as well as moderate the influence of family characteristics on behavior. Using multilevel linear models, we examined the relationship among neighborhood conditions (poverty and social capital) and maternal depression on child and adolescent behavior problems. The sample included 741 children, age 5–11, and 564 adolescents, age 12–17. Outcomes were internalizing (e.g. anxious/depressed) and externalizing (e.g. aggressive/hyperactive) behavior problems. Neighborhood poverty and maternal depression were both positively associated with behavior problems for children and adolescents. However, while neighborhood social capital was not directly associated with behavior problems, the interaction of social capital and maternal depression was significantly related to behavior problems for adolescents. This interaction showed that living in neighborhoods with higher levels of social capital attenuated the relationship between maternal depression and adolescent behavior problems and confirmed the expectation that raising healthy well-adjusted children depends not only on the family, but also the context in which the family lives.

"Sustaining the Shrinking City: Concepts, Dynamics and ...

EPA Pesticide Factsheets

Sustainability can be broadly defined as the resilient outcome of the interaction among social equity, economic stability, and environmental quality factors. For example, the utilization of natural resource capitals are constrained by economic forces, and further modulated by social norms and perceptions. Nowhere is this more apparent than in cities, where the social, economic and environmental capital within the city and in its supporting region may wax and wane due to internal dynamics and external drivers. These changes may be charted as shifts in land use, the type and qualities of infrastructure, population and its demography, and other characteristics that drive the trajectory of a city toward shrinkage. Our authors will discuss how fluxes of different capitals (social, cultural, financial, technological, natural resources, governance/political) might align or substitute for each other to create conditions in the structure and function of city to attain a sustainable size after undergoing a rapid depopulation. Other authors focus on how the misalignment of capitals can doom a city to shrink uncontrollably, and in combination with shifts in environmental quality, the may destroy a city’s ability to function as an integrative center for social and economic interactions. We see this special issue as an attractive venue for data-based research on environmental factors as they impact change in the socio-cultural, economic, political, and physiographic feature

Concerns regarding the social-behavioral maladjustment of U.S. youth have spurred efforts among educators and policymakers to identify and remedy educational contexts that exacerbate children's anxiety, depression, aggression, and misconduct. However, investigations of the influence of collective classroom student characteristics on individuals' social-behavioral functioning are few. The present study examined concurrent and longitudinal relations between adversity factors facing the collective classroom student group and levels of children's internalizing and externalizing behaviors across the elementary school years, and whether the pattern of relations differed for girls and boys. First-, third-, and fifth-grade teachers reported on the extent to which adversity-related factors (e.g., home/family life, academic readiness, social readiness, English proficiency, tardiness/absenteeism, student mobility, health) presented a challenge in their classrooms (i.e., classroom-level adversity [CLA]). Mothers reported on their child's internalizing and externalizing behavior at each grade. Autoregressive, lagged panel models controlled for prior levels of internalizing and externalizing behavior, mothers' education, family income-to-needs, and class size. For all children at each grade, CLA was concurrently and positively associated with externalizing behavior. For first-grade girls, but not boys, CLA was also concurrently and positively associated with internalizing behavior. Indirect effects suggested CLA influenced later internalizing and externalizing behavior through its influence on maladjustment in a given year. Discussion highlights possible methods of intervention to reduce CLA or the negative consequences associated with being in a higher-adversity classroom.

The authors examined the relations of maternal supportive parenting to effortful control and internalizing problems (i.e., separation distress, inhibition to novelty), externalizing problems, and social competence when toddlers were 18 months old (n = 256) and a year later (n = 230). Mothers completed the Coping With Toddlers' Negative Emotions Scale, and their sensitivity and warmth were observed. Toddlers' effortful control was measured with a delay task and adults' reports (Early Childhood Behavior Questionnaire). Toddlers' social functioning was assessed with the Infant/Toddler Social and Emotional Assessment. Within each age, children's regulation significantly mediated the relation between supportive parenting and low levels of externalizing problems and separation distress, and high social competence. When using stronger tests of mediation, controlling for stability over time, the authors found only partial evidence for mediation. The findings suggest these relations may be set at an early age.

Research suggests that perceived social stress influences illness presentation and course among youth in the clinical high-risk (CHR) phase of psychosis. Little is known, however, about the social cognitive factors associated with social stress perception in this population, particularly relative to youth with non-CHR psychopathology. Individuals with psychosis tend to endorse an external locus of control (LOC), which is associated with the stress response in healthy individuals. LOC may therefore be related to perceived social stress in youth at CHR. We examined the differential relations of self-reported LOC and perceived social stress, as measured by the Behavior Assessment System for Children, Second Edition, across 45 CHR and 65 help-seeking control (HSC) participants. Youth at CHR reported more social stress (F[1, 107]=6.28, p=0.01) and a more external LOC (F[1, 107]=4.98, p=0.03) than HSCs. Further, external LOC was more strongly associated with feelings of social stress in the CHR group relative to the HSC group (interaction: b=0.35, t[105]=2.32, p<0.05, f 2 =0.05). Group differences in social stress, however, were nonsignificant at internal levels of LOC (b=-2.0, t[105]=-0.72, p=0.48; f 2 =0.00). Results suggest that perceptions of uncontrollability over one's social environment may more often induce or exacerbate feelings of stress and tension in CHR youth relative to HSCs. A better understanding of the social cognition-stress relation may improve understanding of CHR phenomenology, etiology, and treatment. Copyright © 2016 Elsevier B.V. All rights reserved.

Mentalization and the left inferior frontal gyrus and insula.

To determine if an interpersonal attribution bias associated with self-perception, the externalizing bias, was related to neural activations during mentalization. A functional magnetic resonance imaging task involving verbal appraisals measured neural activations when thinking about oneself and others in 59 adults, including healthy women as well as women with and recovered from anorexia nervosa. Whole-brain regressions correlated brain function during mentalization with the externalizing bias measured using the Internal, Personal, and Situational Attributions Questionnaire. Women with anorexia nervosa had a lower externalizing bias, demonstrating a tendency to self-attribute more negative than positive social interactions, unlike the other groups. The externalizing bias was correlated with activation of the left inferior frontal gyrus and posterior insula, when comparing thinking about others evaluating oneself with direct self-evaluation. Externalizing biases may provide an office-based assay reflecting neurocognitive disturbances in social self-perception that are common during anorexia nervosa.

2016-09-01

In this article, our aim is to analyze institutional practices guided to promote the development of moral values within the context of military education of Brazilian Army combatant commissioned officers. From a cultural psychological approach, we discuss how social guidance within military culture operates at different levels of the affective-semiotic regulation of individuals, structuring complex experiences that give rise to hypergeneralized meaning fields regarding morality and military values. For this goal, we first introduce some theoretical topics related to values development, emphasizing their affective roots and role in the emergence, maintenance, amplification and attenuation of all relations between the person and the environment. Following a brief discussion on how social institutions try to promote changes in personal values, we provide an overview of values present in the military culture and socialization. Finally, the text focuses on the education of Brazilian Army combatant commissioned officers, describing how practices related to different levels of affective-semiotic experience combine in order to promote the internalization and externalization of specific moral values. We conclude suggesting issues for future investigation.

[Regulation of Positive and Negative Emotions as Mediator between Maternal Emotion Socialization and Child Problem Behavior].

2015-01-01

The present study investigated five to six year old children's ability to regulate negative and positive emotions in relation to psychosocial problem behavior (N=53). It was explored, whether mothers' supportive and nonsupportive strategies of emotion socialization influence children's problem behavior by shaping their emotion regulation ability. Mothers reported on children's emotion regulation and internalizing and externalizing problem behavior via questionnaire, and were interviewed about their preferences for socialization strategies in response to children's expression of negative affect. Results showed that children with more adaptive expression of adequate positive emotions had less internalizing behavior problems. When children showed more control of inadequate negative emotions, children were less internalizing as well as externalizing in their behavior. Furthermore, results indicated indirect relations of mothers' socialization strategies with children's problem behavior. Control of inadequate negative emotions mediated the link between non-supportive strategies on externalizing problem behavior. Results suggest that emotion regulatory processes should be part of interventions to reduce the development of problematic behavior in young children. Parents should be trained in dealing with children's emotions in a constructive way.

Despite high rates of grandmother involvement with young grandchildren, very little research has examined the associations between non-residential grandmother involvement and grandchild social adjustment. The present study draws 127 families enrolled in the Family Transitions Project to consider the degree to which mother-reported maternal grandmother involvement buffers 3- and 4-year old grandchildren from economic, parenting, and child temperamental risks for reduced social competence and elevated externalizing behaviors. Findings indicate that higher levels of mother-reported grandmother involvement reduced the negative association between observed grandchild negative emotional reactivity and social competence. Further, high levels of mother-reported grandmother involvement protected grandchildren from the positive association between observed harsh mother parenting and grandchild externalizing behaviors. These findings underscore the relevance of moving beyond the nuclear family to understand factors linked to social adjustment during early childhood. PMID:20954774

Young children exhibiting severe externalizing problems in school are at risk of developing several poor outcomes. School-based intervention programs have been found to be effective for students with different problems, including those with behavioral problems, emotional distress, or social problems. The present study investigated whether the IY-TCM programme, as a universal stand-alone school intervention programme, reduced severe child externalizing problems as reported by the teacher, and evaluated if these children improved their social competence, internalizing problems, academic performances and student- teacher relationship as a result of the IY TCM training. A quasi-experimental pre-post study was conducted, including 21 intervention schools and 22 control schools. Children in 1 st - 3 rd grade (age 6-8 years) assessed by their teacher as having severe externalizing problems on the Sutter-Eyberg Student Behavior Inventory-Revised (SESBI-R) total Intensity score, were included in the study, N = 83 (65 boys and 18 girls). Treatment effects were evaluated using 3- level linear mixed models analysis. In our study we found no differences in change between the two conditions from baseline to follow-up in externalizing problems, social skills, internalizing problems and closeness with teacher. The intervention condition did however show advantageous development in terms of student-teacher conflicts and increased academic performances. The IY Teacher Classroom Management program is not sufficient being a stand-alone universal program in a Norwegian primary school setting, for students with severe externalizing problems. However; some important secondary findings were found. Still, young school children with severe externalizing problems are in need of more comprehensive and tailored interventions.

How Are Scientists Using Social Media in the Workplace?

2016-01-01

Social media has created networked communication channels that facilitate interactions and allow information to proliferate within professional academic communities as well as in informal social circumstances. A significant contemporary discussion in the field of science communication is how scientists are using (or might use) social media to communicate their research. This includes the role of social media in facilitating the exchange of knowledge internally within and among scientific communities, as well as externally for outreach to engage the public. This study investigates how a surveyed sample of 587 scientists from a variety of academic disciplines, but predominantly the academic life sciences, use social media to communicate internally and externally. Our results demonstrate that while social media usage has yet to be widely adopted, scientists in a variety of disciplines use these platforms to exchange scientific knowledge, generally via either Twitter, Facebook, LinkedIn, or blogs. Despite the low frequency of use, our work evidences that scientists perceive numerous potential advantages to using social media in the workplace. Our data provides a baseline from which to assess future trends in social media use within the science academy.

The study of eating behaviour should consider the presence of potential sources of bias, including social desirability. This is particularly relevant among students of Nutrition Sciences, since they have a higher risk of eating disorders. To analyse the effect of social desirability in the assessment of eating behaviour dimensions among nutrition students. In this cross-sectional study, we analysed data from 149 students of Nutrition Sciences. Participants completed a questionnaire assessing social desirability and eating behaviour dimensions (emotional, external and binge eating, flexible and rigid control, and eating self-efficacy). Among males, social desirability had a negative association with binge eating, while among women it had a negative association with emotional, external and binge eating and a positive association with eating self-efficacy. In both subsamples, social desirability showed no significant association with any of the two types of dietary restraint (rigid and flexible control). Overall, the association between social desirability and eating behaviour dimensions among students of Nutrition Sciences occurs in the same direction as found in students from other areas. However, alongside these similarities, there is a stronger association between social desirability and binge eating among male students of Nutrition Sciences. We hypothesize that this may be related with the different knowledge of students from different areas, and the way they perceive and face the treatment of eating disorders. Our study shows that social desirability should be considered while assessing eating behaviour among nutrition students, particularly when studying external eating, binge eating and eating self-efficacy. Moreover, when tailoring interventions to reduce the possible effects of eating behaviour on nutritionists and dieticians' practice, we should consider the influence of social desirability.

The objective was to determine to what extent daily physical education can be implemented in primary schools, what barriers exist and how to overcome the mentioned barriers. Moreover, it was analysed to what extent daily physical education is accepted by teachers, external trainers, parents and students. Semi-structured interviews with parents (n=7), teachers (n=5) and external trainers (n=6) of the intervention schools. The intervention students (n=44) were surveyed within focus groups. All surveyed groups appraised the implementation of daily school sports as successful. The cooperation between the schools and the sports club should be maintained during a comprehensive implementation of daily physical education. Besides an improved lessons quality teachers and external trainers reported an improved social behaviour of the children. Parents perceived positive effects on the child development. All groups believe that daily physical education increases the enjoyment of children in sports. As a certain barrier a lack of resources (e. g., facilities, equipment, financial resources) in the schools were mentioned. The cooperation between the schools and the sports club proved to be an applicable model to implement daily physical education. The combination of teachers and external trainers can contribute to a higher lesson quality. Considering the perceived potentials of daily physical education by all surveyed groups, a comprehensive implementation of systematic daily physical activity promotion in the primary school setting should be tapped more strongly in future. © Georg Thieme Verlag KG Stuttgart · New York.

[Evidence-based medicine - the current self-reflection of an individualised approach to medicine as an action science].

PubMed

Behrens, Johann

2010-01-01

Evidence-based Medicine (EbM) is the ongoing self-reflection of an individualised approach to medicine in terms of a science that originates from and focuses on clinical decision-making (pragmatic science="Handlungswissenschaft"). EbM is particularly suitable for self-reflecting individualised medicine on the basis of decision-oriented pragmatic science because it consistently distinguishes between external evidence (i.e., other subjects' experience gained through "qualitative" and "quantitative" scientific methods) and internal evidence, i.e., the individual user's, or patient's, own experience manifesting and developing in the individual contact between therapist and patient. Therefore, internal evidence is completely different from the individual clinical experience, expertise, and conviction which therapists contribute to the encounter with clients. A deeper understanding of internal evidence as a result of this encounter has emerged only in the past 15 years. However, it is an integral part of the logic of evidence-based professional decision-making. Scientifically justified beneficial and effective treatment in the individual case cannot be deduced from external evidence but can only be gathered from internal evidence for which the best external evidence available has been utilised. In the past 15 years nursing science has not only carved out the decision-oriented scientific core of evidence-based practice but has also tried to increase the validity of studies on external evidence by employing a combination of 'qualitative' social science studies and clinical epidemiological methods.

2009-11-01

We examined associations between basal respiratory sinus arrhythmia (RSA) in conjunction with RSA regulation with the hypothesis that their interaction would explain unique variability in children's prospective adjustment 2 years later. Participants were 176 children (98 girls; 78 boys) in middle childhood. RSA regulation was assessed through social and problem-solving challenges. Parents reported on children's internalizing and externalizing symptoms. Interactions between RSA baseline and regulation to the social stressor predicted children's later internalizing symptoms. Interactions between RSA baseline and responding to the problem-solving stressor predicted children's externalizing symptoms. The highest levels of internalizing symptoms were predicted for children with both lower basal RSA and higher RSA suppression. The highest levels of externalizing symptoms were predicted for children who demonstrated lower basal RSA in conjunction with RSA augmentation. Findings highlight the importance of the contemporaneous consideration of basal RSA and RSA regulation in the prediction of developmental psychopathology symptomology.

Previous research has found a strong correlation between children’s academic self-concept and their behavioral problems. The present study examined whether children’s peer rejection moderated the relationship between children’s math and verbal self-concepts and their behavioral problems at school. We expected that children’s social competence, as measured by peer rejection, moderated the negative effect of low self-concept on children’s externalizing behaviors. Participants were 173 children (males = 93, Mage = 10.31 years, SD = 1.43). The main findings showed that peer rejection moderated the effect of both low verbal and math self-concepts on children’s externalizing behavior. The results are discussed in terms of the protective factor played by children’s social competence reducing the impact of low self-concept on children’s externalizing behaviors. PMID:29163290

Racial socialization messages appear to have varying impacts on the adjustment of African American youth. To further explore this, we examined how two types of racial socialization messages might influence African American youth internalizing and externalizing behavior. The Youth Self Report was used to measure these behavior outcomes. Given that racial socialization messages may not be directly linked to behavior outcomes, we considered private regard, an aspect of racial identity, to serve as a mediator. Additionally, we examined global self-esteem as a mediator of the complex dynamic between racial socialization messages and behavior outcomes. Adolescents in our study completed paper assessments. Majority of the participants were female (56 %) and reside in a metropolitan area in the Mid-Atlantic region. Adolescent’s ages ranged from 14 to 17 years with the average age being 15 years old. Path analysis revealed cultural pride and alertness to discrimination messages varied in their relation to private regard. Results also indicated a strong linkage between private regard, global self-esteem, and internalizing behaviors. Interestingly, the linkage between private regard, global self-esteem and externalizing behaviors was not as robust. Further, private regard appeared to directly and indirectly impact externalizing behaviors. The implications of these findings for racial socialization strategies, identity development (racial and global) as it pertains to behavior problems for African American adolescents are discussed.

Advantage and choice: social relationships and staff assistance in assisted living.

Burge, Stephanie; Street, Debra

2010-05-01

OBJECTIVES. To understand how "cumulative inequality" (CI), expressed as individual advantage and choice, and "external social supports" contribute to the quality of social relationships and perceptions of staff assistance for older individuals in different assisted living (AL) settings. Data are from 429 cognitively intact AL residents aged 60 years and older interviewed for the Florida Study of Assisted Living. Bivariate and multivariate statistical analyses show how individual advantage and choice and external social networks influence respondents' social relationships and staff assistance in AL. Controlling for resident and facility characteristics, being able to pay privately enhances resident satisfaction with staff assistance and having control over the move to AL is positively associated with perceptions of staff relationships and assistance. Maintaining contact with pre-AL friends predicts quality of coresident relationships, as does family contact. Regular contact with family buffers some of the disadvantages associated with CI for perceptions of staff relationships but not perceptions of staff assistance. Discussion. Individual advantage and choice influence the quality of staff relationships and assistance for AL residents but matter little for coresident relationships. External social relationships buffer some of the risks associated with CI for perceptions of staff relationships but not perceived quality of staff assistance. Findings highlight outcomes associated with CI, including predictable risks that disadvantaged elders face in particular types of AL settings, differential advantages others enjoy that influence positive perceptions of staff relationships and staff assistance, and the enduring importance of supportive social relationships.

Predicting externalizing and internalizing behavior in kindergarten: examining the buffering role of early social support.

2015-01-01

This study tested an ecological model predicting children's behavior problems in kindergarten from risk and protective factors (parent psychological distress, parenting behavior, and social support) during early childhood. Study participants were 1,161 sociodemographically diverse mother-child pairs that participated in a longitudinal birth cohort study. The predictor variables were collected at two separate time points and based on parent reports; children were an average of 2 years old at Time 1 and 3 years old at Time 2. The outcome measures were collected when children reached kindergarten and were 6 years old on average. Our results show that early maternal psychological distress, mediated by suboptimal parenting behavior, predicts children's externalizing and internalizing behaviors in kindergarten. Moreover, early social support buffers the relations between psychological distress and later suboptimal parenting behavior and between suboptimal parenting behavior and later depressive/withdrawn behavior. Our findings have several implications for early intervention and prevention efforts. Of note, informal social support appears to play an important protective role in the development of externalizing and internalizing behavior problems, weakening the link between psychological distress and less optimal parenting behavior and between suboptimal parenting behavior and children's withdrawal/depression symptoms. Increasing social support may be a productive goal for family and community-level intervention.

The purpose of this study was to investigate whether the core members' social capital was associated with individually perceived and externally evaluated prestige and cooperation among the HIV/AIDS-related civil society organizations (CSOs). To accomplish this, a cross-sectional study using multistage sampling was carried out in eight provinces of China. Data were collected from the 327 core members via questionnaires and self-evaluated performance of the respondents were evaluated and measured. The interviews were conducted with all core members and the supervisory staff of the local Centers for Disease Control and Prevention. Multivariate logistic regression analysis indicated that social support (adjusted odds ratio [a OR] = 1.87) and organizational commitment (a OR = 1.57) were significantly associated with a higher odds of prestige performance in self-evaluation. Furthermore, social support (a OR = 1.65), trust (a OR = 1.33), and organizational commitment (a OR = 1.52) were significantly correlated with cooperation performance. Trust was positively associated with the cooperation performance on external evaluation. These findings may provide a new perspective on challenges that the CSOs face in response to a growing HIV/AIDS epidemic in China. Social capital may increase performance and accelerate organizational growth, ultimately improving HIV/AIDS prevention and care.

Mathematics learning achievement is influenced by the internal and external factor of the students. One of the influencing external factors is social interaction with friends in learning activities. In modern learning, the learning is student-centered, so the student interaction is needed to learn about certain basic competence. Potential and motivation of students in learning are expected to develop with good social interaction in order to get maximum results. Social interaction is an important aspect of learning Mathematics because students get the opportunity to express their own thoughts in order to encourage a reflection on the knowledge they have. This research uses the correlational descriptive method involving 36 students for the tenth grade, eleventh grade, and twelfth grade of SMA Negeri 1 Wuryantoro and data collecting technique using questionnaire for social interaction and documentation for learning outcome. The result of this research shows that learning achievement and social interaction of students are not good. Based on the result of data analysis, it is shown that the social interaction and Mathematics learning achievement are still in the low level. This research concludes that students’ social interaction influences student learning achievement in Mathematics subjects.

Exposure to Violence, Social Information Processing, and Problem Behavior in Preschool Children

2012-01-01

Understanding the mechanisms by which early risk factors for social maladjustment contribute to disruptive behaviors in social settings is vital to developmental research and practice. A major risk factor for social maladjustment is early exposure to violence which was examined in this short-term longitudinal study in relation to social information processing patterns and externalizing and internalizing behaviors in a sample of 256 preschool children. Data on exposure to violence were obtained via parent report, data on social information processing were obtained via child interview, and data on child problem behavior were obtained via teacher report. Findings supported the hypothesis that, compared to children not exposed to violence, children reported to witness and/or experience violence are more likely to attribute hostile intent to peers, generate aggressive responses, and evaluate socially unaccepted responses (aggressive and inept) as socially suitable. The former were also found to exhibit higher levels of externalizing and internalizing behaviors. Finally, social information processing mediated the link between exposure to violence and problem behavior thus supporting this study’s general approach which argues that the link between exposure to violence and children’s problem behaviors are better understood within the context of their perceptions about social relationships.

Adverse early life experience and development may have long-term health consequences, but later environmental conditions may perhaps protect against the effects of such early life adversities. The aim was to investigate whether cause-specific and overall mortality rates among adoptees are associated with the age at which they were transferred to the adoptive family and whether the social class of the adoptive family modifies this association. A cohort of 10,592 non-familial adoptions (biologically unrelated adoptee and adoptive parents) of Danish-born children formally granted in 1924-47 and with follow-up of total and cause-specific mortality through ages up to 85 years. The rates of death after the age of 16 from all causes combined, all natural causes, all external causes, and suicide were compared according to the age at which adoptees were transferred to their adoptive family by estimating hazard ratios in Cox regression models. Death rates from all causes were significantly higher in adoptees transferred between age 1 month and 4 years compared to those transferred immediately after birth with the hazard ratio peaking at 1.19 (95% confidence limit: 1.08 to 1.32) for adoptees transferred between 6 and 11 months. This result was primarily driven by a similar pattern for natural causes of death. For death from external causes and for suicide the hazard ratios were increasing with increasing age at transfer, and tests for trend were statistically significant. The social class of the adoptive family did not significantly modify these associations. Transfer to an adoptive family later than at the time of birth may have adverse long-term consequences affecting overall and cause-specific mortality. These effects were not modified by the environment provided by the adoptive family as indicated by the social class of these families.

Tibial lengthening using a humeral intramedullary nail combined with a single-plane external fixator for leg discrepancy in sequelae of poliomyelitis.

2011-03-01

The sequelae of poliomyelitis are the common causes of leg discrepancy. Tibial lengthening is an effective way to solve this problem but it is associated with a high rate of complications. In this study, we combined the use of humeral nail and external fixator in tibial lengthening with the purpose of reducing lengthening complications. Compared with the cases lengthened by a single-plane external fixator alone, this combined strategy was found to be beneficial in maintaining the tibial alignment. Therefore, it can be recommended as a good technique for tibial lengthening in patients with sequelae of poliomyelitis.

The purpose of this study was to examine factors associated with the presence of secondary external and internal lymphedema in patients with head-and-neck cancer (HNC). The sample included 81 patients ≥3 months after HNC treatment. Physical and endoscopic examinations were conducted to determine if participants had external, internal, and/or combined head-and-neck lymphedema. Logistic regression analysis was used to examine the factors associated with the presence of lymphedema. The following factors were statistically significantly associated with presence of lymphedema: (1) location of tumor associated with presence of external (P=.009) and combined lymphedema (P=.032); (2) time since end of HNC treatment associated with presence of external (P=.004) and combined lymphedema (P=.005); (3) total dosage of radiation therapy (P=.010) and days of radiation (P=.017) associated with the presence of combined lymphedema; (4) radiation status of surgical bed was associated with the presence of internal lymphedema, including surgery with postoperative radiation (P=.030) and (salvage) surgery in the irradiated field (P=.008); and (5) number of treatment modalities associated with external (P=.002), internal (P=.039), and combined lymphedema (P=.004). No demographic, health behavior-related, or comorbidity factors were associated with the presence of lymphedema in the sample. Select tumor and treatment parameters are associated with increased occurrence of lymphedema in patients with HNC. Larger and longitudinal studies are needed to identify adjusted effects and causative risk factors contributing to the development of lymphedema in patients with HNC. Copyright © 2012 Elsevier Inc.

Mulder, Juul; Bogt, Tom Ter; Raaijmakers, Quinten; Vollebergh, Wilma

2007-04-01

Internalizing and externalizing problems differ by musical tastes. A high school-based sample of 4159 adolescents, representative of Dutch youth aged 12 to 16, reported on their personal and social characteristics, music preferences and social-psychological functioning, measured with the Youth Self-Report (YSR). Cluster analysis on their music preferences revealed six taste groups: Middle-of-the-road (MOR) listeners, Urban fans, Exclusive Rock fans, Rock-Pop fans, Elitists, and Omnivores. A seventh group of musically Low-Involved youth was added. Multivariate analyses revealed that when gender, age, parenting, school, and peer variables were controlled, Omnivores and fans within the Exclusive Rock groups showed relatively high scores on internalizing YSR measures, and social, thought and attention problems. Omnivores, Exclusive Rock, Rock-Pop and Urban fans reported more externalizing problem behavior. Belonging to the MOR group that highly appreciates the most popular, chart-based pop music appears to buffer problem behavior. Music taste group membership uniquely explains variance in both internalizing and externalizing problem behavior.

Kopala-Sibley, Daniel C; Klein, Daniel N

2017-04-01

Little research has examined the effect of subtypes of social withdrawal on the development of psychopathology across childhood. Parents of 493 children (220 females) completed a measure of their child's conflicted shyness and social disinterest as well as the Child Behaviour Checklist (CBCL) when their child was age 3, and again at age 6. When children were age 9, parents completed the CBCL. From 3 to 6, conflicted shyness predicted increases in anxiety symptoms in boys and girls, and predicted depressive symptoms in boys. From 6 to 9, social disinterest predicted increases in anxiety symptoms in girls and boys, and predicted increases in depressive symptoms in boys. In addition, in boys, conflicted shyness at age 6 predicted increases in externalizing symptoms at age 9. Conflicted shyness appears to be particularly problematic in early to middle childhood, while social disinterest appears to be more maladaptive in later childhood, with some differences by gender.

In science findings which cannot be extrapolated to other settings are of little value. Recruitment methods vary widely across chronic whiplash studies, but it remains unclear whether this generates recruitment bias. The present study aimed to examine whether the recruitment method accounts for differences in health status, social support, and personality traits in patients with chronic whiplash-associated disorders (WAD). Two different recruitment methods were compared: recruiting patients through a local whiplash patient support group (group 1) and local hospital emergency department (group 2). The participants (n=118) filled in a set of questionnaires: the Neck Disability Index, Medical Outcome Study Short-Form General Health Survey, Anamnestic Comparative Self-Assessment measure of overall well-being, Symptom Checklist-90, Dutch Personality Questionnaire, and the Social Support List. The recruitment method (either through the local emergency department or patient support group) accounted for the differences in insufficiency, somatization, disability, quality of life, self-satisfaction, and dominance (all p values <.01). The recruitment methods generated chronic WAD patients comparable for psychoneurotism, social support, self-sufficiency, (social) inadequacy, rigidity, and resentment (p>.01). The recruitment of chronic WAD patients solely through patient support groups generates bias with respect to the various aspects of health status and personality, but not social support. In order to enhance the external validity of study findings, chronic WAD studies should combine a variety of recruitment procedures.

Examining social competence, self-perception, quality of life, and internalizing and externalizing symptoms in adolescent females with and without autism spectrum disorder: a quantitative design including between-groups and correlational analyses.

Adolescent females with an autism spectrum disorder (ASD) are an understudied population, yet are also quite vulnerable, due to the increased complexities of social interaction and increased risk for internalizing symptoms in adolescence. Most research literature currently focuses on males with ASD, limiting our understanding of social experiences for females with ASD, and thus the potential to better inform supports and intervention to promote social-emotional functioning. This study examined similarities and differences in selected indicators of social-emotional health (social competence, self-perception, quality of life) and problematic behaviors such as externalizing and internalizing symptoms for adolescent females with and without ASD. This study employed a quantitative design utilizing correlational analysis as well as t test comparisons to examine selected indicators of social-emotional health and problematic symptoms using the Social Skills Improvement System (SSIS), Youth Quality of Life Instrument (YQOL), and the Self-Perceptions Profile for Adolescents (SPPA) for adolescent females with ASD in relation to their typically developing peers. Significant differences were found between females with and without ASD in terms of their self-ratings of social-emotional health and problematic behaviors. The no-ASD group rated themselves higher across all areas of social-emotional health. Findings also suggest strong relationships between these constructs, especially for females without ASD. Parent reports of autism symptoms and social-emotional health indicated that as symptoms of autism are more severe, so too was the impact on individuals' social competence. Adolescent females with ASD perceive themselves as having lower social competence, self-worth, and quality of life and higher levels of internalizing and externalizing symptoms as compared to their typically developing peers. Parent ratings indicate that higher levels of autism symptoms relate to lower levels of social competence. These findings lend support to the postulate that adolescent females with ASD are more vulnerable than their typically developing counterparts due to the compounded impact of ASD symptoms on social-emotional health and the higher risk for internalizing disorders for adolescent girls. Limitations and implications for further research and intervention are discussed.

Paths from Mother-Child and Father-Child Relationships to Externalizing Behavior Problems in Children Differing in Electrodermal Reactivity: a Longitudinal Study from Infancy to Age 10

Electrodermal hyporeactivity (or low skin conductance level, SCL) has been long established as a correlate of and diathesis for antisocial behavior, aggression, disregard for rules of conduct and feelings of others, and generally, externalizing behavior problems in children and adults. Much less is known, however, about how individual differences in children’s SCL and qualities of their early experiences in relationships with parents interact to produce antisocial outcomes. In a community sample of 102 families (51 girls), we examined children’s SCL, assessed in standard laboratory tasks at age 8 (N=81), as a moderator of the links between parent–child socialization history and children’s externalizing behavior problems at ages 8 and 10, reported by mothers and fathers in well-established instruments and by children in clinical interviews. Mother- and father-child socialization history was assessed in frequent, intensive observations. Parent–child mutually responsive orientation (MRO) was observed from infancy to age 10, parental power assertion was observed from 15 months to age 6 ½, and children reported their attachment security in interviews at age 8 and 10. For children with lower SCL, variations in mothers’ power assertion and father-child MRO were associated with parent-rated externalizing problems. The former interaction was consistent with diathesis-stress, and the latter with differential susceptibility. For children with higher SCL, there were no links between socialization history and externalizing problems. PMID:25218772

Background Worldwide, over one billion children and adolescents live in war-affected settings. At present, only limited research has investigated linkages between disrupted social ecology and adverse mental health outcomes among war-affected youth. In this study, we examine three community-level characteristics—social disorder and collective efficacy within the community, as reported by caregivers, and perceived stigma as reported by youth—in relation to externalizing behaviors and internalizing symptoms among male and female former child soldiers in post-conflict Sierra Leone. Methods 243 former child soldiers (30% female, mean age at baseline: 16.6 years) and their primary caregivers participated in interviews in 2004 and 2008, as part of a larger prospective cohort study of war-affected youth in Sierra Leone. Two-point growth models were estimated to examine the relationship between community-level characteristics and externalizing and internalizing outcomes across the time points. Results Both social disorder within the community, reported by caregivers, and perceived stigma, reported by youth, positively co-varied with youths’ externalizing and internalizing scores—indicating that higher levels of each at baseline and follow-up were associated with higher levels of mental health problems at both time points (p<0.05). The relationship between collective efficacy and mental health outcomes was non-significant (p>0.05). Conclusions This study offers a rare glimpse into the role that the post-conflict social context plays in shaping mental health among former child soldiers. Results indicate that both social disorder and perceived stigma within the community demonstrate an important relationship to externalizing and internalizing problems among adolescent ex-combatants. Moreover, these relationships persisted over a four-year period of follow up. These results underscore the importance of the post-conflict social environment and the need to develop post-conflict interventions that address community-level processes in addition to the needs of the individual.

Economic exchange games have rarely been applied to examine psychopathology in youth. In the current study we adapted a trust game to investigate the relations between externalizing behavior problems, trust, and trustworthiness. We were particularly interested in the differential modulating impact of "known identity" (vs. anonymous) condition of the task. Second, we examined whether anomalies in trust behavior would correspond to social cognition manifested in children with externalizing problems. A total of 171 (79 age-matched pairs) boys (mean age = 12.84; SD = 1.80) were recruited from community groups where social networks and relationships amongst peers have been established. A trust game was played under two conditions: an anonymous version where the identity of the trust game partner was not known and a "known identity" version where identities were revealed. Results supported the conclusion that boys with externalizing behavior problems are generally less trustworthy, but not less trusting and that this was true especially for the known identity version of the game. Moreover, anomalies in trust behavior were associated with hostile intentions, but not reflective of a general theory of mind deficit. This study contributes to an emerging literature using economic exchange games to investigate real-time, real-life exchanges in relation to psychopathology.

Heberle, Amy E.; Krill, Sarah C.; Briggs-Gowan, Margaret J.; Carter, Alice S.

2014-01-01

Objective This study tested an ecological model predicting children’s behavior problems in kindergarten from risk and protective factors (parent psychological distress, parenting behavior, and social support) during early childhood. Method Study participants were 1161 socio-demographically diverse mother-child pairs who participated in a longitudinal birth cohort study. The predictor variables were collected at two separate time points and based on parent reports; children were an average of two years old at Time 1 and three years old at Time 2. The outcome measures were collected when children reached Kindergarten and were six years old on average. Results Our results show that early maternal psychological distress, mediated by sub-optimal parenting behavior, predicts children’s externalizing and internalizing behaviors in kindergarten. Moreover, early social support buffers the relations between psychological distress and later sub-optimal parenting behaviors and between sub-optimal parenting behavior and later depressive/withdrawn behavior. Conclusions Our findings have several implications for early intervention and prevention efforts. Of note, informal social support appears to play an important protective role in the development of externalizing and internalizing behavior problems, weakening the link between psychological distress and less optimal parenting behavior and between sub-optimal parenting behavior and children’s withdrawal/depression symptoms. Increasing social support may be a productive goal for family and community-level intervention. PMID:24697587

Concern in patients with bladder exstrophy after reconstruction regarding potential injury to pelvic neurourological anatomy and a resultant functional deficit prompted combined (simultaneous) cystometrography and electromyography after complete primary repair of bladder exstrophy. We determined whether complete primary repair of bladder exstrophy would adversely affect the innervation controlling bladder and external urethral sphincter function. Complete primary repair of bladder exstrophy was performed via a modified Mitchell technique in newborns without osteotomy. Postoperative evaluation included combined cystometrography and needle electrode electromyography via the perineum, approximating the external urethral sphincter muscle complex. Electromyography was done to evaluate the external urethral sphincter response to sacral reflex stimulation and during voiding. Nine boys and 4 girls underwent combined cystometrography/electromyography after complete primary repair of bladder exstrophy. Age at study and time after complete primary repair of bladder exstrophy was 3 months to 10 years (median 11.5 months). Cystometrography revealed absent detrusor overactivity and the presence of a sustained detrusor voiding contraction in all cases. Electromyography showed universally normal individual motor unit action potentials of biphasic pattern, amplitude and duration. The external urethral sphincter sacral reflex response was intact with a normal caliber with respect to Valsalva, Credé, bulbocavernosus and anocutaneous (bilateral) stimulation. Synergy was documented by abrupt silencing of external urethral sphincter electromyography activity during voiding. After complete primary repair of bladder exstrophy combined cystometrography/electromyography in patients with bladder exstrophy showed normal neurourological findings, including sacral reflex responses, sustained detrusor voiding contraction and synergic voiding, in all patients postoperatively. These findings confirm the safety of complete primary repair of bladder exstrophy. Based on our results we have discontinued routine electromyography in these patients.

Exposure to violence, social information processing, and problem behavior in preschool children.

PubMed

Ziv, Yair

2012-01-01

Understanding the mechanisms by which early risk factors for social maladjustment contribute to disruptive behaviors in social settings is vital to developmental research and practice. A major risk factor for social maladjustment is early exposure to violence, which was examined in this short-term longitudinal study in relation to social information processing (SIP) patterns and externalizing and internalizing behaviors in a sample of 256 preschool children. Data on exposure to violence were obtained via parent report, data on SIP were obtained via child interview, and data on child problem behavior were obtained via teacher report. Findings supported the hypothesis that, compared to children not exposed to violence, children reported to witness and/or experience violence are more likely to attribute hostile intent to peers, generate aggressive responses, and evaluate socially unaccepted responses (aggressive and inept) as socially suitable. The former were also found to exhibit higher levels of externalizing and internalizing behaviors. Finally, SIP mediated the link between exposure to violence and problem behavior thus supporting this study's general approach, which argues that the link between exposure to violence and children's problem behaviors are better understood within the context of their perceptions about social relationships. © 2012 Wiley Periodicals, Inc.

To study effects of long-term administration of fenspiride in combination with broncholytic drugs on dynamics of clinical symptoms, external respiration function and quality of life in patients with chronic obstructive pulmonary disease (COPD). A comparative randomized trial of fenspiride used for 6 months in combination with broncholytic drugs enrolled 68 COPD patients. A clinical status, external respiration function were examined. Quality of life was evaluated with WHO questionnaire WHOQOL-100. Addition of fenspiride to combined treatment of COPD attenuates COPD symptoms, normalizes blood biochemistry, improves external respiration function, raises exercise tolerance. Quality of life improved by physical and mental state scales. Fenspiride addition to COPD treatment improves efficacy of the standard treatment and is recommended for treatment of COPD of stage I and II in combination with broncholytic drugs.

Does sexual selection explain human sex differences in aggression?

PubMed

Archer, John

2009-08-01

I argue that the magnitude and nature of sex differences in aggression, their development, causation, and variability, can be better explained by sexual selection than by the alternative biosocial version of social role theory. Thus, sex differences in physical aggression increase with the degree of risk, occur early in life, peak in young adulthood, and are likely to be mediated by greater male impulsiveness, and greater female fear of physical danger. Male variability in physical aggression is consistent with an alternative life history perspective, and context-dependent variability with responses to reproductive competition, although some variability follows the internal and external influences of social roles. Other sex differences, in variance in reproductive output, threat displays, size and strength, maturation rates, and mortality and conception rates, all indicate that male aggression is part of a sexually selected adaptive complex. Physical aggression between partners can be explained using different evolutionary principles, arising from the conflicts of interest between males and females entering a reproductive alliance, combined with variability following differences in societal gender roles. In this case, social roles are particularly important since they enable both the relatively equality in physical aggression between partners from Western nations, and the considerable cross-national variability, to be explained.

Adaptation of the ESPA29 Parental Socialization Styles Scale to the Basque language: evidence of validity.

PubMed

López-Jáuregui, Alicia; Oliden, Paula Elosua

2009-11-01

The aim of this study is to adapt the ESPA29 scale of parental socialization styles in adolescence to the Basque language. The study of its psychometric properties is based on the search for evidence of internal and external validity. The first focuses on the assessment of the dimensionality of the scale by means of exploratory factor analysis. The relationship between the dimensions of parental socialization styles and gender and age guarantee the external validity of the scale. The study of the equivalence of the adapted and original versions is based on the comparisons of the reliability coefficients and on factor congruence. The results allow us to conclude the equivalence of the two scales.

Enhanced male-evoked responses in the ventromedial hypothalamus of sexually receptive female mice.

PubMed

Nomoto, Kensaku; Lima, Susana Q

2015-03-02

Social encounters often start with routine investigatory behaviors before developing into distinct outcomes, such as affiliative or aggressive actions. For example, a female mouse will initially engage in investigatory behavior with a male but will then show copulation or rejection, depending on her reproductive state. To promote adaptive social behavior, her brain must combine internal ovarian signals and external social stimuli, but little is known about how socially evoked neural activity is modulated across the reproductive cycle [1]. To investigate this, we performed single-unit recordings in the ventrolateral region of the ventromedial hypothalamus (VMHvl) in freely behaving, naturally cycling, female mice interacting with conspecifics of both genders. The VMHvl has been implicated in rodent sociosexual behavior [2, 3]: it has access to social sensory stimuli [4-8] and is involved in aggression and mating [9-11]. Furthermore, many VMHvl neurons express ovarian hormone receptors [12, 13], which play a central role in female sociosexual behavior [14-16]. We found that a large fraction of VMHvl neurons was activated in the presence of conspecifics with preference to male stimuli and that the activity of most VMHvl neurons was modulated throughout social interactions rather than in response to specific social events. Furthermore, neuronal responses to male, but not female, conspecifics in the VMHvl were enhanced during the sexually receptive state. Thus, male-evoked VMHvl responses are modulated by the reproductive state, and VMHvl neural activity could drive gender-specific and reproductive state-dependent sociosexual behavior.

Identifying Childhood Characteristics that Underlie Pre-Morbid Risk for Substance Use Disorders: Socialization and Boldness

PubMed Central

Hicks, Brian M.; Iacono, William G.; McGue, Matt

2013-01-01

Utilizing a longitudinal twin study (N = 2510), we identified the child characteristics present prior to initiation of substance use that best predicted later substance use disorders. Two independent traits accounted for the majority of pre-morbid risk: socialization (conformity to rules and conventional values) and boldness (sociability and social assurance, stress resilience, and thrill seeking). Low socialization was associated with disruptive behavior disorders, parental externalizing disorders, and environmental adversity, and exhibited moderate genetic (.45) and shared environmental influences (.30). Boldness was highly heritable (.71) and associated with less internalizing distress and environmental adversity. Together, these traits exhibited robust associations with adolescent and young adult substance use disorders (R = .48 and .50, respectively), and incremental prediction over disruptive behavior disorders, parental externalizing disorders, and environmental adversity. Results were replicated in an independent sample. Socialization and boldness offer a novel conceptualization of underlying risk for substance use disorders that has the potential to improve prediction and theory with implications for basic research, prevention, and intervention.

Seeking for the Definition of "Culture": Current Concerns and their Implications. A Comment on Gustav Jahoda's Article "Critical Reflections on some Recent Definitions of "Culture'"'.

PubMed

Mironenko, Irina A; Sorokin, Pavel S

2018-06-01

This article takes as a starting point the critical analysis of attempts to define "culture", offered by Jahoda in 2012. Basing on the observed proliferation of various, often contradicting, definitions of "culture" (for instance, trying to refer to its both internal and external aspects), Jahoda arrives at the conclusion that attempts to define the concept of "culture" are vain and useless and it is quite practicable simply to use the term without seeking to define it. We find it hard to agree with this statement. Elaborating on Jahoda reflections and drawing on the recent debates in social sciences, cultural studies and philosophy, we argue that seeking for the definition of culture is necessary in the context of contemporary development of social and humanitarian knowledge. Moreover, we claim that the debates about culture indicate the need for a large-scale methodological reorganization of the social and humanitarian sciences, in response to the novel ontological congruence between internal and external, the fundamental "ontological shift", "reversing the poles" of the human-related reality. The human individual becomes its core element and pivot. Other "objects", "external" in relation to the individual (for instance, social structures and institutions), undergo such massive and rapid changes that grow progressively fuzzy and sometimes even less "real", comparing to the individual. The "inner" nature of the individual also transforms: from being "subjected" to think, act and feel according to certain external conditions, an individual becomes an Actor, who is empowered to change the environment following his purposive plans, desires and visions.

Working from the inside out: a case study of Mackay Safe Community.

Hanson, Dale; Gunning, Colleen; Rose, Judy; McFarlane, Kathryn; Franklin, Richard C

2015-04-01

Mackay Whitsunday Safe Community (MWSC) was established in 2000 in response to high rates of injury observed in the region. MWSC assumed an ecological perspective, incorporating targeted safety promotion campaigns reinforced by supportive environments and policy. By involving the community in finding its own solutions, MWSC attempted to catalyze structural, social, and political changes that empowered the community and, ultimately, individuals within the community, to modify their environment and their behavior to reduce the risk of injury. A community network consisting of 118 members and an external support network of 50 members was established. A social network analysis conducted in 2000 and 2004 indicated that the network doubled its cohesiveness, thereby strengthening its ability to collaborate for mutual benefit. However, while MWSC was rich in social resources, human and financial resources were largely controlled by external agencies. The bridging and linking relationships that connected MWSC to its external support network were the social mechanism MWSC used to access the resources it required to run programs. These boundary-spanning relationships accessed an estimated 6.5 full-time equivalents of human resources and US$750,000 in 2004 that it used to deliver a suite of injury control and safety promotion activities, associated with a 33% reduction in injury deaths over the period 2002 to 2010. MWSC can only be understood in its ecological context. The productivity of MWSC was vulnerable to the changing policy priorities of external sponsoring agents and critically dependent on the advocacy skills of its leaders. © 2015 Society for Public Health Education.

Agent-Based Models in Social Physics

NASA Astrophysics Data System (ADS)

Quang, Le Anh; Jung, Nam; Cho, Eun Sung; Choi, Jae Han; Lee, Jae Woo

2018-06-01

We review the agent-based models (ABM) on social physics including econophysics. The ABM consists of agent, system space, and external environment. The agent is autonomous and decides his/her behavior by interacting with the neighbors or the external environment with the rules of behavior. Agents are irrational because they have only limited information when they make decisions. They adapt using learning from past memories. Agents have various attributes and are heterogeneous. ABM is a non-equilibrium complex system that exhibits various emergence phenomena. The social complexity ABM describes human behavioral characteristics. In ABMs of econophysics, we introduce the Sugarscape model and the artificial market models. We review minority games and majority games in ABMs of game theory. Social flow ABM introduces crowding, evacuation, traffic congestion, and pedestrian dynamics. We also review ABM for opinion dynamics and voter model. We discuss features and advantages and disadvantages of Netlogo, Repast, Swarm, and Mason, which are representative platforms for implementing ABM.

A longitudinal study of child maltreatment, mother-child relationship quality and maladjustment: the role of self-esteem and social competence.

PubMed

Kim, Jungmeen; Cicchetti, Dante

2004-08-01

This study examined the concurrent and longitudinal relations of mother-child relationship quality, self-esteem, social competence, and maladjustment among maltreated (n = 206) and nonmaltreated (n = 139) school-aged children from low-income families. Results of the path analysis using structural equation modeling revealed that maltreatment at Time 1 was related to internalizing and externalizing symptomatology at Time 1, both directly as well as indirectly, through its influence on social competence at Time 1. Regardless of maltreatment status, secure mother-child relationship quality was negatively related to internalizing symptomatology at Time 1 and to internalizing and externalizing symptomatology at Time 2 via its influence on self-esteem at Time 1. The results are discussed as suggestive of the role of self-esteem and social competence as mediating mechanisms in the link between relational risks and children's maladjustment.

Self-regulation and social pressure reduce prejudiced responding and increase the motivation to be non-prejudiced.

PubMed

Buzinski, Steven G; Kitchens, Michael B

2017-01-01

Self-regulation constrains the expression of prejudice, but when self-regulation falters, the immediate environment can act as an external source of prejudice regulation. This hypothesis derives from work demonstrating that external controls and internal self-regulation can prompt goal pursuit in the absence of self-imposed controls. Across four studies, we found support for this complementary model of prejudice regulation. In Study 1, self-regulatory fatigue resulted in less motivation to be non-prejudiced, compared to a non-fatigued control. In Study 2, strong (vs. weak) perceived social pressure was related to greater motivation to be non-prejudiced. In Study 3, dispositional self-regulation predicted non-prejudice motivation when perceived social pressure was weak or moderate, but not when it was strong. Finally, in Study 4 self-regulatory fatigue increased prejudice when social pressure was weak but not when it was strong.

Social class, contextualism, and empathic accuracy.

PubMed

Kraus, Michael W; Côté, Stéphane; Keltner, Dacher

2010-11-01

Recent research suggests that lower-class individuals favor explanations of personal and political outcomes that are oriented to features of the external environment. We extended this work by testing the hypothesis that, as a result, individuals of a lower social class are more empathically accurate in judging the emotions of other people. In three studies, lower-class individuals (compared with upper-class individuals) received higher scores on a test of empathic accuracy (Study 1), judged the emotions of an interaction partner more accurately (Study 2), and made more accurate inferences about emotion from static images of muscle movements in the eyes (Study 3). Moreover, the association between social class and empathic accuracy was explained by the tendency for lower-class individuals to explain social events in terms of features of the external environment. The implications of class-based patterns in empathic accuracy for well-being and relationship outcomes are discussed.

Hosokawa, Rikuya; Katsura, Toshiki

2017-01-01

Using a short-term longitudinal design, this study examined the concurrent and longitudinal relationships among familial socioeconomic status (SES; i.e., family income and maternal and paternal education levels), marital conflict (i.e., constructive and destructive marital conflict), parenting practices (i.e., positive and negative parenting practices), child social competence (i.e., social skills), and child behavioral adjustment (i.e., internalizing and externalizing problems) in a comprehensive model. The sample included a total of 1604 preschoolers aged 5 years at Time 1 and first graders aged 6 years at Time 2 (51.5% male). Parents completed a self-reported questionnaire regarding their SES, marital conflict, parenting practices, and their children's behavioral adjustment. Teachers also evaluated the children's social competence. The path analysis results revealed that Time 1 family income and maternal and paternal education levels were respectively related to Time 1 social skills and Time 2 internalizing and externalizing problems, both directly and indirectly, through their influence on destructive and constructive marital conflict, as well as negative and positive parenting practices. Notably, after controlling for Time 1 behavioral problems as mediating mechanisms in the link between family factors (i.e., SES, marital conflict, and parenting practices) and behavioral adjustment, Time 1 social skills significantly and inversely influenced both the internalization and externalization of problems at Time 2. The merit of examining SES, marital conflict, and parenting practices as multidimensional constructs is discussed in relation to an understanding of processes and pathways within families that affect child mental health functioning. The results suggest social competence, which is influenced by the multidimensional constructs of family factors, may prove protective in reducing the risk of child maladjustment, especially for children who are socioeconomically disadvantaged.

Self-reported Cognitive Biases Moderate the Associations Between Social Stress and Paranoid Ideation in a Virtual Reality Experimental Study.

PubMed

2018-06-06

Cognitive biases are associated with psychosis liability and paranoid ideation. This study investigated the moderating relationship between pre-existing self-reported cognitive biases and the occurrence of paranoid ideation in response to different levels of social stress in a virtual reality environment. This study included 170 participants with different levels of psychosis liability (55 recent onset psychosis, 20 ultrahigh risk for psychosis, 42 siblings of psychotic patients, and 53 controls). All participants were exposed to virtual environments with different levels of social stress. The level of experienced paranoia in the virtual environments was measured with the State Social Paranoia Scale. Cognitive biases were assessed with a self-report continuous measure. Also, cumulative number of cognitive biases was calculated using dichotomous measures of the separate biases, based on general population norm scores. Higher belief inflexibility bias (Z = 2.83, P < .001), attention to threat bias (Z = 3.40, P < .001), external attribution bias (Z = 2.60, P < .001), and data-gathering bias (Z = 2.07, P < .05) were all positively associated with reported paranoid ideation in the social virtual environments. Level of paranoid response increased with number of cognitive biases present (B = 1.73, P < .001). The effect of environmental stressors on paranoid ideation was moderated by attention to threat bias (Z = 2.78, P < .01) and external attribution bias (Z = 2.75, P < .01), whereas data-gathering bias and belief inflexibility did not moderate the relationship. There is an additive effect of separate cognitive biases on paranoid response to social stress. The effect of social environmental stressors on paranoid ideation is further enhanced by attention to threat bias and external attribution bias.

The United States aerospace industry is experiencing profound changes created by a combination of domestic actions and circumstances such as airline deregulation. Other changes result from external trends such as emerging foreign competition. These circumstances intensify the need to understand the production, transfer, and utilization of knowledge as a precursor to the rapid diffusion of technology. Presented here is a conceptual framework for understanding the diffusion of technology. A conceptual framework is given for understanding the diffusion of aerospace knowledge. The framework focuses on the information channels and members of the social system associated with the aerospace knowledge diffusion process, placing particular emphasis on aerospace librarians as information intermediaries.

An attributional analysis of excuse giving: studies of a naive theory of emotion.

Weiner, B; Amirkhan, J; Folkes, V S; Verette, J A

1987-02-01

We conducted four studies that pertained to excuses given for a broken social contract. In an initial field investigation, participants recalled occasions in which they had given true and false reasons for not fulfilling a social obligation. Communicated reasons tended to be external to the person, uncontrollable, and unintentional (e.g., "My car broke down"), whereas withheld reasons tended to be internal, controllable, and either intentional (e.g., "I did not want to go") or unintentional (e.g., "I forgot"). The external uncontrollable excuses were anticipated to lessen the anger of the wronged party. In a subsequent simulation study, excuses based on the categories detected in Experiment 1 were manipulated and related to anger ratings. The same pattern of results was displayed, with intent and negligence provoking the highest anger ratings. The final two studies involved laboratory manipulation of a communicated reason for coming late to an experiment. In Experiment 3, a confederate conveyed either an internal controllable, an external uncontrollable, or no reason for making a subject wait, whereas in Experiment 4, subjects were detained and created their own good, bad, any, or no excuse for being tardy, which was communicated to a second, waiting subject. A consistent pattern of good excuse/external uncontrollable reason and bad excuse/internal controllable reason was displayed; offering no excuse resulted in the same judgments as giving a poor excuse. Relative to the external uncontrollable reasons, internal controllable excuses for being late augmented aversive emotional reactions, increased negative personality ratings, and resulted in a desire for no further social contact.(ABSTRACT TRUNCATED AT 250 WORDS)

We used an Ilizarov external fixator and a nail (10 mm diameter in 17 tibiae and 11 mm in one tibia) in combination. Average limb lengthening was 4.19 cm (range, 2.5–5.5). The mean duration of external fixation was 12.58 days per centimetre gain in length, and the mean consolidation index was 40.53 (range, 35.45–51.85). All distracted segments healed spontaneously without refracture or malalignment. Gradual limb lengthening using a reamed type intramedullary nail and circular external fixation in combination was found to be reliable and effective and reduced external fixation time with fewer complications.

Spectral beam combining of a broad area diode laser is a promising technique for direct diode laser applications. We present an experimental study of three mini-bar stacks in an external cavity on spectral beam combining in conjunction with spatial beam combining. At the pump current of 70 A, a CW output power of 579 W, spectral bandwidth of 18.8 nm and electro-optical conversion efficiency of 47% are achieved. The measured M 2 values of spectral beam combining are 18.4 and 14.7 for the fast and the slow axis, respectively. The brightness of the spectral beam combining output is 232 MW · cm-2 · sr-1.

Good intentions, increased inequities: developing social care services in Emergency Departments in the UK.

Addressing the quality of services provided in Emergency Departments (EDs) has been a central area of development for UK government policy since 1997. Amongst other aspects of this concern has been the recognition that EDs constitute a critical boundary between the community and the hospital and a key point for the identification of social care needs. Consequently, EDs have become the focus for a variety of service developments which combine the provision of acute medical and nursing assessment and care with a range of activities in which social care is a prominent feature. One approach to this has been the establishment of multidisciplinary teams aiming to prevent re-attendance or admission, re-direct patients to other services, or speed patients through EDs with the aim of providing improved quality of care. This study, carried out between September 2007 and April 2008, was the first UK national survey of social care initiatives based in EDs and aimed to determine the objectives, organisation, extent, functions, funding and evidence on outcomes of such interventions. Eighty-three per cent of UK Type I and II EDs responded to the survey. Approximately, one-third of EDs had embedded social care teams, with two-thirds relying on referrals to external social care services. These teams varied in their focus, size and composition, leadership, availability, funding and permanence. As a result, the unintended effect has been to increase inequities in access to social care services through EDs. Three further conclusions are drawn about policy led, locally-based service development. This survey adds to international evidence pointing to the potential benefits of a variety of social care interventions being based in EDs and justifies the establishment of a research programme which can provide answers to key outstanding questions. © 2011 Blackwell Publishing Ltd.

Clinical trials on technology transfer models are rare, even with the interest in advancing the uptake of evidence-based practices in social service agencies. This article presents the results from a trial examining different transfer strategies to assist juvenile justice caseworkers in using screening, assessment, and case planning practices to address mental health and substance use needs. Study findings examine factors that promote organizational readiness. A clinical trial was conducted examining the impact of three post-training strategies: an external coach to build the social network of the justice office (build social climate), an external coach to educate staff (build skills and knowledge), and a control condition consisting of traditional management directives (directives to staff of agency priorities). All groups were exposed to a 1 day refresher course in motivational interviewing. The social network and skill building groups also attended an intensive 3-day training followed by three on-site booster sessions over a 12 month period of time. Twelve juvenile justice offices (with their 231 juvenile justice staff) were assigned to one of three conditions. The study examined the impact of different transfer conditions on organizational readiness to implement the innovation of screening, assessment, and referral strategies. External coaching targeting the social climate of the justice office to support innovations improved organizational readiness to change, regardless of office size. Coaching that targeted either the social climate or staff knowledge and skills both improved organizational readiness for change compared to management directives, but social climate coaching resulted in greater improvements in receptivity to change. No individual level features of case workers (e.g., age, gender, years of experience) significantly predicted organizational readiness to change. Unexpectedly, the skill and knowledge building approach did not perform any better than management directives only (no post training) efforts. Organizational readiness has been found to be an important factor supporting agencies' adoption of evidence-based practices. Techniques devoted to attending to the social climate are critical to increasing organizational readiness. External coach facilitators can accomplish this through modest means (three post training booster sessions) that build internal expertise and resiliency in support of the change. This is a low cost method of preparing a low resourced environment such as juvenile justice agencies to use evidence-based practices.

Allahbakhsh, Hamidreza; Shariati, Mahmoud

2013-10-01

A series of finite element analysis on the cracked composite cylindrical shells under combined loading is carried out to study the effect of loading condition, crack size and orientation on the buckling behavior of laminated composite cylindrical shells. The interaction buckling curves of cracked laminated composite cylinders subject to different combinations of axial compression, bending, internal pressure and external pressure are obtained, using the finite element method. Results show that the internal pressure increases the critical buckling load of the CFRP cylindrical shells and bending and external pressure decrease it. Numerical analysis show that axial crack has the most detrimental effect on the buckling load of a cylindrical shell and results show that for lower values of the axial compressive load and higher values of the external pressure, the buckling is usually in the global mode and for higher values of axial compressive load and lower levels of external pressure the buckling mode is mostly in the local mode.

Pricing landfill externalities: emissions and disamenity costs in Cape Town, South Africa.

PubMed

Nahman, Anton

2011-01-01

The external (environmental and social) costs of landfilling (e.g. emissions to air, soil and water; and 'disamenities' such as odours and pests) are difficult to quantify in monetary terms, and are therefore not generally reflected in waste disposal charges or taken into account in decision making regarding waste management options. This results in a bias against alternatives such as recycling, which may be more expensive than landfilling from a purely financial perspective, but preferable from an environmental and social perspective. There is therefore a need to quantify external costs in monetary terms, so that different disposal options can be compared on the basis of their overall costs to society (financial plus external costs). This study attempts to estimate the external costs of landfilling in the City of Cape Town for different scenarios, using the benefits transfer method (for emissions) and the hedonic pricing method (for disamenities). Both methods (in particular the process of transferring and adjusting estimates from one study site to another) are described in detail, allowing the procedures to be replicated elsewhere. The results show that external costs are currently R111 (in South African Rands, or approximately US$16) per tonne of waste, although these could decline under a scenario in which energy is recovered, or in which the existing urban landfills are replaced with a new regional landfill.

This report is the proceedings of the National Conference on Environmental Externalities. A environmental externality is the environmental impact of a process or a plant that society must endure. It is a social cost and is paid, but not by the company who produced it or the company`s customers who endure it. The main purpose of this report is to gather the many designs and ideas of how and why to internalize the externalities into the pricing systems of the public utility commissions, especially that of the electric utilities. Economic and sociological aspects of the internalization of these externalities aremore » given in these proceedings. Individual papers are processed separately for databases. (MB)« less

Intelligence, Attention, and Behavioral Outcomes in Internationally Adopted Girls with a History of Institutionalization.

2015-01-01

The aim of this study was to investigate the association of neurocognitive functioning with internalizing and externalizing problems and school and social competence in children adopted internationally. Participants included girls between the ages of 6-12 years who were internationally adopted from China (n = 32) or Eastern Europe (n = 25) and a control group of never-adopted girls (n = 25). Children completed the Vocabulary and Matrix Reasoning subtests from the Wechsler Abbreviated Scale of Intelligence and the Score! and Sky Search subtests from the Test of Everyday Attention for Children. Parents completed the Child Behavior Checklist and the Home and Community Social Behavior Scales. Compared to the controls, the Eastern European group evidenced significantly more problems with externalizing behaviors and school and social competence and poorer performance on measures of verbal intelligence, perceptual reasoning, and auditory attention. More internalizing problems were reported in the Chinese group compared to the controls. Using generalized linear regression, interaction terms were examined to determine whether the associations of neurocognitive functioning with behavior varied across groups. Eastern European group status was associated with more externalizing problems and poorer school and social competence, irrespective of neurocognitive test performance. In the Chinese group, poorer auditory attention was associated with more problems with social competence. Neurocognitive functioning may be related to behavior in children adopted internationally. Knowledge about neurocognitive functioning may further our understanding of the impact of early institutionalization on post-adoption behavior.

Stress, social behavior, and resilience: Insights from rodents

PubMed Central

Beery, Annaliese K.; Kaufer, Daniela

2014-01-01

The neurobiology of stress and the neurobiology of social behavior are deeply intertwined. The social environment interacts with stress on almost every front: social interactions can be potent stressors; they can buffer the response to an external stressor; and social behavior often changes in response to stressful life experience. This review explores mechanistic and behavioral links between stress, anxiety, resilience, and social behavior in rodents, with particular attention to different social contexts. We consider variation between several different rodent species and make connections to research on humans and non-human primates. PMID:25562050

Voting contagion: Modeling and analysis of a century of U.S. presidential elections

de Aguiar, Marcus A. M.

2017-01-01

Social influence plays an important role in human behavior and decisions. Sources of influence can be divided as external, which are independent of social context, or as originating from peers, such as family and friends. An important question is how to disentangle the social contagion by peers from external influences. While a variety of experimental and observational studies provided insight into this problem, identifying the extent of contagion based on large-scale observational data with an unknown network structure remains largely unexplored. By bridging the gap between the large-scale complex systems perspective of collective human dynamics and the detailed approach of social sciences, we present a parsimonious model of social influence, and apply it to a central topic in political science—elections and voting behavior. We provide an analytical expression of the county vote-share distribution, which is in excellent agreement with almost a century of observed U.S. presidential election data. Analyzing the social influence topography over this period reveals an abrupt phase transition from low to high levels of social contagion, and robust differences among regions. These results suggest that social contagion effects are becoming more instrumental in shaping large-scale collective political behavior, with implications on democratic electoral processes and policies.

Criss, Michael M.; Pettit, Gregory S.; Bates, John E.; Dodge, Kenneth A.; Lapp, Amie L.

2009-01-01

Peer acceptance and friendships were examined as moderators in the link between family adversity and child externalizing behavioral problems. Data on family adversity (i.e., ecological disadvantage, violent marital conflict, and harsh discipline) and child temperament and social information processing were collected during home visits from 585 families with 5-year-old children. Children's peer acceptance, friendship, and friends' aggressiveness were assessed with sociometric methods in kindergarten and grade 1. Teachers provided ratings of children's externalizing behavior problems in grade 2. Peer acceptance served as a moderator for all three measures of family adversity, and friendship served as a moderator for harsh discipline. Examination of regression slopes indicated that family adversity was not significantly associated with child externalizing behavior at high levels of positive peer relationships. These moderating effects generally were not qualified by child gender, ethnicity, or friends' aggressiveness, nor were they accounted for by child temperament or social information-processing patterns. The need for process-oriented studies of risk and protective factors is stressed. PMID:12146744

2008-09-01

Dietary-reporting validation study data and school foodservice production records were used to examine intrusions (reports of uneaten items) in school meals in 24-h recalls. Fourth-grade children [20 low-BMI (> or = 5th and < 50th percentiles); 20 high-BMI (> or = 85th percentile); 50% boys; 75% black] were each observed eating two school meals (breakfast, lunch) and interviewed about the prior 24h that evening (24E) or the previous day the next morning (PDM). Social desirability was assessed. Intrusions were classified as stretches (on meal tray), internal confabulations (in school foodservice environment but not on meal tray), and external confabulations (not in school foodservice environment). For breakfast, reported items were less likely to be intrusions for black than white children, and for low-BMI boys than the other BMI-x-sex groups, and to be external confabulations for high-BMI girls than high-BMI boys. For lunch, reported items and intrusions were more likely to be stretches for 24E than PDM interviews. As social desirability increased, fewer items were reported for breakfast, and reported items and intrusions were more likely to be internal confabulations for lunch. For breakfast, compared to low-BMI girls, as social desirability increased, intruded amounts were larger for high-BMI boys and smaller for high-BMI girls. For lunch, intruded amounts were smaller for high-BMI girls than the other BMI-x-sex groups. Amounts reported were smaller for stretches than internal confabulations and external confabulations for breakfast, and external confabulations for lunch. To better understand intrusions, dietary-reporting validation studies are needed with larger samples by BMI-group, sex, and race.

The role of grandparents in preventing aggressive and other externalizing behavior problems in children from rural, methamphetamine-involved families

Sheridan, Kathryn; Haight, Wendy L.; Cleeland, Leah

2011-01-01

Preventive interventions are urgently needed for children from rural, methamphetamine-involved families, who are at risk for the development of aggressive and other externalizing behavioral problems. This mixed method study explored naturally occurring sources of protection and considers the implications for targeted interventions. Participants were 41 children aged six to 14 years from rural families involved with methamphetamine and the public child welfare system, their primary caregivers, and 19 parents recovering from methamphetamine addiction. When invited during semi-structured interviews to talk about their families, 48% of children spontaneously described socially and emotionally supportive relationships with healthy grandparents. Children’s reports of support from grandparents were associated with lower scores on CBCL Social Problems, [t(37)= 2.23, p<.05 ]; externalizing behaviors, [t(37)= 2.07, p<.05]; and aggressive behaviors, [t(37)= 2.75, p<.01]. When asked to talk about their families, 58% of parents spontaneously described the support their children received from grandparents, and 26% also described the support that they had received from their own grandparents. Children’s and parents’ descriptions of grandparent support suggest how grandparents may protect children from the development of aggressive and other externalizing behavior problems. First, grandparents may prevent obstacles to healthy development by providing their grandchildren with safe shelter and basic child care when parents are incapacitated from substance misuse. Second, they may promote their grandchildren’s positive social-emotional development through supportive relationships. Third, they may promote social competence through enjoyable leisure activities with healthy adults and non-delinquent peers. Understanding naturally occurring sources of protection for children can inform the development of interventions by identifying strengths on which to build, and suggesting culturally sensitive approaches when children are struggling.

Time on your hands: Perceived duration of sensory events is biased toward concurrent actions.

PubMed

Yon, Daniel; Edey, Rosanna; Ivry, Richard B; Press, Clare

2017-02-01

Perceptual systems must rapidly generate accurate representations of the world from sensory inputs that are corrupted by internal and external noise. We can typically obtain more veridical representations by integrating information from multiple channels, but this integration can lead to biases when inputs are, in fact, not from the same source. Although a considerable amount is known about how different sources of information are combined to influence what we perceive, it is not known whether temporal features are combined. It is vital to address this question given the divergent predictions made by different models of cue combination and time perception concerning the plausibility of cross-modal temporal integration, and the implications that such integration would have for research programs in action control and social cognition. Here we present four experiments investigating the influence of movement duration on the perceived duration of an auditory tone. Participants either explicitly (Experiments 1-2) or implicitly (Experiments 3-4) produced hand movements of shorter or longer durations, while judging the duration of a concurrently presented tone (500-950 ms in duration). Across all experiments, judgments of tone duration were attracted toward the duration of executed movements (i.e., tones were perceived to be longer when executing a movement of longer duration). Our results demonstrate that temporal information associated with movement biases perceived auditory duration, placing important constraints on theories modeling cue integration for state estimation, as well as models of time perception, action control and social cognition.

The Administration on Aging funded six New York University Caregiver Intervention (NYUCI) demonstration projects, a counseling/support intervention targeting dementia caregivers and families. Three sites (Georgia, Utah, Wisconsin) pooled data to inform external validity in nonresearch settings. This study (a) assesses collective changes over time, and (b) compares outcomes across sites on caregiver burden, depressive symptoms, satisfaction with social support, family conflict, and quality of life. Data included baseline/preintervention ( N = 294) and follow-up visits (approximately 4, 8, 12 months). Linear mixed models showed that social support satisfaction increased ( p < .05) and family conflict decreased ( p < .05; Cohen's d = 0.49 and 0.35, respectively). Marginally significant findings emerged for quality of life increases ( p = .05) and burden decreases ( p < .10). Depressive symptoms remained stable. Slopes did not differ much by site. NYUCI demonstrated external validity in nonresearch settings across diverse caregiver samples.

The Significance of Attachment Security for Children’s Social Competence with Peers: A Meta-Analytic Study

This meta-analytic review examines the association between attachment during the early life course and social competence with peers during childhood, and compares the strength of this association with those for externalizing and internalizing symptomatology. Based on eighty independent samples (N = 4,441), the association between security and peer competence was significant (d = 0.39, CI 0.32; 0.47) and not moderated by the age at which peer competence was assessed. Avoidance (d = 0.17, CI 0.05; 0.30), resistance (d = 0.29, CI 0.09; 0.48), and disorganization (d = 0.25, CI 0.10; 0.40) were significantly associated with lower peer competence. Attachment security was significantly more strongly associated with peer competence than internalizing (but not externalizing) symptomatology. Discussion focuses on the significance of early attachment for the development of peer competence versus externalizing and internalizing psychopathology. PMID:24547936

This new Theory has proposed: (a) in general, the importance of the cyclical model of individual self-regulation (SR) and of external regulation stemming from the context (ER), as two different and complementary variables, both in combination and in interaction; (b) specifically, in the teaching-learning context, the relevance of different types of combinations between levels of self-regulation (SR) and of external regulation (ER) in the prediction of self-regulated learning (SRL), and of cognitive-emotional achievement. This review analyzes the assumptions, conceptual elements, empirical evidence, benefits and limitations of SRL vs. ERL Theory . Finally, professional fields of application and future lines of research are suggested.

In daily life, interpersonal interactions are influenced by uncertainty about other people's intentions. Face-to-face (FF) interaction reduces such uncertainty by providing external visible cues such as facial expression or body gestures and facilitates shared intentionality to promote belief of cooperative decisions and actual cooperative behaviors in interaction. However, so far little is known about interpersonal brain synchronization between two people engaged in naturally occurring FF interactions. In this study, we combined an adapted ultimatum game with functional near-infrared spectroscopy (fNIRS) hyperscanning to investigate how FF interaction impacts interpersonal brain synchronization during economic exchange. Pairs of strangers interacted repeatedly either FF or face-blocked (FB), while their activation was simultaneously measured in the right temporo-parietal junction (rTPJ) and the control region, right dorsolateral prefrontal cortex (rDLPFC). Behaviorally, FF interactions increased shared intentionality between strangers, leading more positive belief of cooperative decisions and more actual gains in the game. FNIRS results indicated increased interpersonal brain synchronizations during FF interactions in rTPJ (but not in rDLPFC) with greater shared intentionality between partners. These results highlighted the importance of rTPJ in collaborative social interactions during FF economic exchange and warrant future research that combines FF interactions with fNIRS hyperscanning to study social brain disorders such as autism. © The Author (2015).

Externalizing disorders are the most common and persistent forms of maladjustment in childhood. The aim of this study was to conduct a meta-analysis evaluating the effectiveness of Cognitive Behavioral Therapy (CBT) to reduce externalizing symptoms in two disorders: Attention Deficit Hyperactivity Disorder (ADHD) and Oppositive Defiant Disorder (ODD). The efficacy of CBT to improve social competence and positive parenting and reduce internalizing behaviors, parent stress and maternal depression was also explored. The database PsycInfo, PsycARTICLES, Medline and PubMed were searched to identify relevant studies. Twenty-one trials met the inclusion criteria. Results showed that the biggest improvement, after CBT, was in ODD symptoms (-0.879) followed by parental stress (-0.607), externalizing symptoms (-0.52), parenting skills (-0.381), social competence (-0.390) and ADHD symptoms (-0.343). CBT was also associated with improved attention (-0.378), aggressive behaviors (-0.284), internalizing symptoms (-0.272) and maternal depressive symptoms (-0.231). Overall, CBT is an effective treatment option for externalizing disorders and is also associated with reduced parental distress and maternal depressive symptoms. Multimodal treatments targeting both children and caregivers' symptoms (e.g. maternal depressive symptoms) appear important to produce sustained and generalized benefits.

Panic attacks are a source of individual suffering and are an independent risk factor for later psychopathology. However, much less is known about risk factors for the development of panic attacks, particularly during adolescence when the incidence of panic attacks increases dramatically. We examined whether internalizing and externalizing problems in childhood predict the onset of panic attacks in adolescence. This study is part of the TRacking Adolescents' Individual Lives Survey (TRAILS), a Dutch longitudinal population cohort study (N = 1,584). Internalizing and Externalizing Problems were collected using the Youth Self-Report (YSR) and the parent-report Child Behavior Checklist (CBCL) at baseline (age 10-12). At age 18-20, DSM-IV defined panic attacks since baseline were assessed with the Composite International Diagnostic Interview (CIDI). We investigated whether early adolescent Internalizing and Externalizing Problems predicted panic attacks between ages 10-20 years, using survival analysis in univariate and multivariate models. There were N = 314 (19.8%) cases who experienced at least one DSM-IV defined panic attack during adolescence and N = 18 (1.2%) who developed panic disorder during adolescence. In univariate analyses, CBCL Total Problems, Internalizing Problems and three of the eight syndrome scales predicted panic attack onset, while on the YSR all broad-band problem scales and each narrow-band syndrome scale predicted panic attack onset. In multivariate analyses, CBCL Social Problems (HR 1.19, p<.05), and YSR Thought Problems (HR 1.15, p<.05) and Social Problems (HR 1.26, p<.01) predicted panic attack onset. Risk indicators of panic attack include the wide range of internalizing and externalizing problems. Yet, when adjusted for co-occurring problem behaviors, Social Problems were the most consistent risk factor for panic attack onsets in adolescence.

How could Theory of Mind contribute to the differentiation of social adjustment profiles of children with externalizing behavior disorders and children with intellectual disabilities?

PubMed

Nader-Grosbois, Nathalie; Houssa, Marine; Mazzone, Stéphanie

2013-09-01

This study compared Theory of Mind (ToM) emotion and belief abilities in 43 children with externalized behavior (EB) disorders presenting low intelligence, 40 children with intellectual disabilities (ID) and 33 typically developing (TD) preschoolers (as a control group), matched for developmental age. The links between their ToM abilities, their level in seven self-regulation strategies as displayed in social problem-solving tasks and their social adjustment profiles (assessed by the Social Competence and Behavior Evaluation, completed by their teachers) were examined. Children with EB presented lower comprehension of causes of emotions and lower self-regulation of joint attention and of attention than children with ID and TD children. In comparison with TD children, lower social adjustment was observed in nearly all dimensions of profiles in both atypical groups. Specifically, children with EB were significantly angrier than children with ID. Although variable patterns of positive correlations were obtained in atypical groups between self-regulation strategies and ToM abilities, the most numerous positive links were obtained in the group with EB. Regression analyses showed that developmental age predicted ToM abilities and certain dimensions of social adjustment profiles in atypical groups. In the ID group, ToM emotions predicted general adaptation, affective adaptation, interactions with peers and with adults and low internalizing problems. In the EB group, general adaptation was predicted by ToM emotions and self-regulation, interactions with peers by ToM beliefs, and a low level of externalizing problems by ToM emotions. Some implications for intervention and perspectives for research are suggested. Copyright © 2013 Elsevier Ltd. All rights reserved.

The Social Attribution Task-Multiple Choice (SAT-MC) tests the ability to extract social themes from viewed object motion. This form of animacy perception is thought to aid the development of social inference, but appears impaired in schizophrenia. The current study was undertaken to examine psychometric equivalence of two forms of the SAT-MC and to compare their performance against social cognitive tests recommended for schizophrenia research. Thirty-two schizophrenia (SZ) and 30 substance use disorder (SUD) participants completed both SAT-MC forms, the Bell-Lysaker Emotion Recognition Task (BLERT), Hinting Task, The Awareness of Social Inference Test (TASIT), Ambiguous Intentions and Hostility Questionnaire (AIHQ) and questionnaire measures of interpersonal function. Test sensitivity, construct and external validity, test-retest reliability, and internal consistency were evaluated. SZ scored significantly lower than SUD on both SAT-MC forms, each classifying ~60% of SZ as impaired, compared with ~30% of SUD. SAT-MC forms demonstrated good test-retest and parallel form reliability, minimal practice effect, high internal consistency, and similar patterns of correlation with social cognitive and external validity measures. The SAT-MC compared favorably to recommended social cognitive tests across psychometric features and, with exception of TASIT, was most sensitive to impairment in schizophrenia when compared to a chronic substance use sample.

Interdisciplinary Matchmaking: Choosing Collaborators by Skill, Acquaintance and Trust

Social networks are commonly used to enhance recommender systems. Most of such systems recommend a single resource or a person. However, complex problems or projects usually require a team of experts that must work together on a solution. Team recommendation is much more challenging, mostly because of the complex interpersonal relations between members. This chapter presents fundamental concepts on how to score a team based on members' social context and their suitability for a particular project. We represent the social context of an individual as a three-dimensional social network (3DSN) composed of a knowledge dimension expressing skills, a trust dimension and an acquaintance dimension. Dimensions of a 3DSN are used to mathematically formalize the criteria for prediction of the team's performance. We use these criteria to formulate the team recommendation problem as a multi-criteria optimization problem. We demonstrate our approach on empirical data crawled from two web2.0 sites: onephoto.net and a social networking site. We construct 3DSNs and analyze properties of team's performance criteria.

Sex-specific relationships among attachment security, social values, and sensation seeking in early adolescence: implications for adolescents' externalizing problem behaviour.

In early adolescence, attachment security reflects not only the quality of ongoing relationships with parents, but also how adolescents process social relationships with "others" - that is, their "social value orientation" - with possible implications for adolescents' risk-taking. In this study, a sample of Italian early adolescents were administered self-report measures in order to examine the relationships (a) between early adolescents' perceived attachment security to mothers and fathers, social values (related to family and the socio-cultural context), and sensation seeking (as a temperamental predisposition to risk-taking), and (b) between these variables and adolescents' externalizing problem behaviour. Adolescents were more securely attached to the same-sexed parent. Further, attachment security with the opposite-sexed parent predicted more conservative social value orientations, and lower levels of problem behaviour. In contrast, sensation seeking predicted self-enhancement and openness-to-change values to a greater extent, and, in girls, lower levels of attachment security to mothers and fathers.

Impact of an individualist vs. collectivist context on the social valorization of internal explanations.

Testé, Benoît

2012-01-01

The theory of the norm of internality emphasizes the role of Western individualism in the normativity of internal explanations. The present study examines the link between the social value accorded to targets expressing internal vs. external explanations and individualist vs. collectivist contexts. Sixty-three male and female French management sciences students evaluated two targets (internal vs. external) in a simulated recruitment situation. The job vacancy was partially manipulated to create individualist vs. collectivist contexts. Participants were asked to state whether or not they would recruit the targets and to describe the targets on traits relating to social utility (market value) and social desirability (likeability). As expected, the results showed that the effect of the targets' internality on recruitment judgments and perceived social utility was stronger in the individualist context than in the collectivist context. However, the analysis also revealed that the participant's gender moderated the impact of the context on the evaluation of the targets. The results showed that the context strongly affected the men's judgments, whereas it had no effect on the women's judgments.

Socially Extended Cognition and Shared Intentionality

PubMed Central

Lyre, Holger

2018-01-01

The paper looks at the intersection of extended cognition and social cognition. The central claim is that the mechanisms of shared intentionality can equally be considered as coupling mechanisms of cognitive extension into the social domain. This claim will be demonstrated by investigating a detailed example of cooperative action, and it will be argued that such cases imply that socially extended cognition is not only about cognitive vehicles, but that content must additionally be taken into account. It is finally outlined how social content externalism can in principle be grounded in socially extended cognition. PMID:29892254

Introduction: Maternal obesity has been shown to be a risk factor for obesity in children and may also affect children's psychosocial outcomes. It is not yet clear whether there are also psycho-emotional mechanisms explaining the effects of maternal weight on young children's weight and psychosocial development. We aimed to evaluate whether maternal body mass index (BMI), mother–child emotional availability (EA), and maternal parenting stress are associated with children's weight and psychosocial development (i.e., internalizing/externalizing symptoms and social competence) and whether these predictors interact with each other. Methods: This longitudinal study included three assessment points (~11 months apart). The baseline sample consisted of N = 194 mothers and their children aged 5–47 months (M = 28.18, SD = 8.44, 99 girls). At t1, we measured maternal weight and height to calculate maternal BMI. We videotaped mother–child interactions, coding them with the EA Scales (fourth edition). We assessed maternal parenting stress with the Parenting Stress Index (PSI) short form. At t1 to t3, we measured height and weight of children and calculated BMI–SDS scores. Children's externalizing and internalizing problems (t1–t3) and social competence (t3, N = 118) were assessed using questionnaires: Child Behavior Checklist (CBCL 1.5–5), Strengths and Difficulties Questionnaire (SDQ: prosocial behavior), and a checklist for behavioral problems at preschool age (VBV 3–6: social-emotional competence). Results: By applying structural equation modeling (SEM) and a latent regression analysis, we found maternal BMI to predict higher BMI–SDS and a poorer psychosocial development (higher externalizing symptoms, lower social competence) in children. Higher parenting stress predicted higher levels of externalizing and internalizing symptoms and lower social competence. Better maternal EA was associated with higher social competence. We found parenting stress to serve as a mediator in the association between maternal weight and children's psychosocial outcomes. Moreover, children of mothers with an elevated BMI were at greater risk of lower social competence only when their mothers showed low levels of maternal EA (moderation). Conclusion: Interventional studies are needed that investigate the causal pathways between parenting stress, mother–child interaction quality and child outcomes. These aspects might be targets to improve the psychosocial development of the offspring of overweight or obese mothers. PMID:27559321

The authors compared the protective effects of 3 sources of perceived social support-from family members, friends, and school personnel-on internalizing and externalizing symptoms in adolescents exposed to rocket attacks. Data were based on 362 Israeli adolescents (median age = 14), chronically exposed to rockets from the Gaza Strip, for whom robust effects of exposure on internalizing and externalizing symptoms were reported during the 2009-2010 period (Henrich & Shahar, 2013). New analyses revealed that perceived family social support assessed in 2009 buffered against the effect of exposure to rocket attacks on depression, aggression, and severe violence during 2009-2010. Findings are consistent with a human-ecological perspective exposure to political violence and encourage the employment of family-based preventive interventions in afflicted areas.

Social support in marriage may be associated with reduced risk for mental illness. Past studies are limited by short follow up and a focus on depression. A two-wave nationally representative survey in the United States (n = 2,503) is used to examine whether social support in marriage is associated with the onset of each of four clusters of disorders-internalizing, externalizing, phobic, and bipolar-10 years later. Results indicate that higher levels of perceived marital support were protective against internalizing, fear, and bipolar disorders, and against incident externalizing disorders for women. Protective effects of social support in marriage against mental illness are long-lasting, and sometimes differ by gender. Findings suggest the importance of mental health assessment in clinical practice. © 2018 American Association for Marriage and Family Therapy.

2013-07-01

The present study examined the role of early fathering in subsequent trajectories of social emotional and academic functioning of preschool children with behavior problems. Participants were 128 preschool-aged children (73 boys, 55 girls) with behavior problems whose biological fathers took part in a longitudinal study. Children were 3 years of age at the beginning of the study and were assessed annually for 3 years. Early paternal depressive symptoms predicted many aspects of children's outcome 3 years later, including externalizing and internalizing problems, social skills deficits, and lower cognitive and academic functioning, and predicted changes in children's externalizing, internalizing, and social problems across the preschool years. Paternal socioeconomic status (SES) also consistently predicted children's later functioning across these domains. Furthermore, self-reported paternal attention-deficit hyperactivity disorder (ADHD) symptoms and laxness, as well as observed frequent commands were associated with later externalizing problems in children. Paternal depressive symptoms and laxness mediated the relation between paternal ADHD symptoms and child functioning. Results suggest that aspects of early father functioning play an important role in the psychosocial, cognitive, and academic development of preschool-aged children with behavior problems.

Grid oscillators

Popovic, Zorana B.; Kim, Moonil; Rutledge, David B.

1988-01-01

Loading a two-dimensional grid with active devices offers a means of combining the power of solid-state oscillators in the microwave and millimeter-wave range. The grid structure allows a large number of negative resistance devices to be combined. This approach is attractive because the active devices do not require an external locking signal, and the combining is done in free space. In addition, the loaded grid is a planar structure amenable to monolithic integration. Measurements on a 25-MESFET grid at 9.7 GHz show power-combining and frequency-locking without an external locking signal, with an ERP of 37 W. Experimental far-field patterns agree with theoretical results obtained using reciprocity.

We demonstrate an external-cavity (EC) beam combining of 4-channel quantum cascade lasers (QCLs) with an output coupler which makes different QCL beams propagating coaxially. A beam combining efficiency of 35% (up to 75% near threshold) is obtained with a beam quality M2 of 5.5. A peak power of 0.64 W is achieved at a wavelength of 4.7 μm. The differences of spot characteristic between coupled and uncoupled are also showed in this letter. The QCLs in this EC system do not have heat crosstalk so that the system can be used for high power beam combining of QCLs.

Structural interventions focused on community mobilisation to engender an enabling social context have reduced sexual risk behaviours among sex workers. Interventions to date have increased social participation and shown an association between participation and safer sex. Social participation could modify risk for other health behaviours, particularly drug use. We assessed social participation and drug use before and after implementation of a clinical, social and structural intervention with sex workers intended to prevent sexually transmitted infections/HIV infection. We followed 420 sex workers participating in the Encontros intervention in Corumbá, Brazil, between 2003 and 2005. We estimated the association of participation in external social groups with drug use at baseline and follow-up using logistic regression and marginal modelling. Follow-up analyses of preintervention/postintervention change in drug use employed inverse probability weighting to account for censoring and were stratified by exposure to the intervention. Social participation showed a protective association with drug use at baseline (1 SD higher level of social participation associated with 3.8% lower prevalence of drug use, 95% CI -0.1 to 8.3). Among individuals exposed to Encontros, higher social participation was associated with an 8.6% lower level of drug use (95% CI 0.1 to 23.3). No significant association was found among the unexposed. A structural intervention that modified sex workers' social environment, specifically participation in external social groups, was associated with reduced drug use. These findings suggest that sexual risk prevention initiatives that enhance social integration among marginalised populations can produce broad health impacts, including reductions in drug use.

Background Although radiation therapy is a primary treatment for craniopharyngioma, it can exacerbate existing problems related to the tumor and pre-irradiation management. Survival is often marked by neurologic deficits, panhypopituitarism, diabetes insipidus, cognitive deficiencies and behavioral and social problems. Procedure The Achenbach Child Behavior Checklist (CBCL) was used to evaluate behavioral and social problems during the first five years of follow-up in 27 patients with craniopharyngioma treated with conformal radiation therapy. Results All group averages for the CBCL scales were within the age-typical range at pre-irradiation baseline. Extent of surgical resection was implicated in baseline differences for the Internalizing, Externalizing, Behavior Problem and Social scores. Significant longitudinal changes were found in Internalizing, Externalizing, Behavior Problem and School scores that correlated with tumor and treatment related factors. Conclusions The most common variables implicated in post-irradiation behavioral and social problems were CSF shunting, presence of an Ommaya reservoir, diabetes insipidus, and low pre-irradiation growth hormone levels.

2013-03-01

Social rank theory has been applied to psychosis, in particular the relationship between an individual and their voices. However, perceived peer group rank has not been empirically tested in an early psychosis group. The purpose of the study was to test the prediction that individuals with early psychosis will have lower perceived social status, engage in submissive behaviours more frequently, and will feel more entrapped by external events compared to a healthy control group. The study employed a cross-sectional design, comparing individuals with early psychosis and healthy controls. A total of 24 participants with early psychosis and 24 matched controls completed self-report measures of social rank, including social comparison, submissive behaviours and entrapment, measures of depression, anxiety and psychotic symptoms, and measures of peer network size and peer relationship quality. Individuals with early psychosis viewed themselves as being of lower social rank and inferior in relation to matched controls, and also reported engaging in submissive behaviours more frequently and felt more entrapped by external events. Perception of lower social rank and inferiority amongst individuals with early psychosis may impact on engagement in peer relationships and impact on the social decline in early psychosis, which could have significant implications for interventions and recovery. ©2012 The British Psychological Society.

The objectives of this study were to examine the association of structural language and pragmatic communication with behavior problems and social competence in girls adopted internationally. Participants included girls between 6-12 years of age who were internationally adopted from China (n = 32) and Eastern-Europe (n = 25) and a control group of never-adopted girls (n = 25). Children completed the Wechsler Abbreviated Scale of Intelligence. Parents completed the Child Communication Checklist- second edition, the Child Behavior Checklist, and the Home and Community Social Behavior Scales. Compared to the controls, parents in the Eastern European group reported more problems with social competence, externalizing behaviors, structural language, and pragmatic communication. The Chinese group evidenced more internalizing problems. Using generalized linear regression, interaction terms were examined to determine if the associations of pragmatic communication and structural language with behavior problems and social competence varied across groups. Controlling for general intellectual functioning, poorer pragmatic communication was associated with more externalizing problems and poorer social competence. In the Chinese group, poorer pragmatic communication was associated with more internalizing problems. Post-adoption weaknesses in pragmatic communication are associated with behavior problems and social competence. Internationally adopted children may benefit from interventions that target pragmatic communication.

Building agribusiness model of LEISA is needed as a prototype of sustainable regional and economic development (SRRED) in the watersheds (DAS) of West Java Province. Agribusiness model of LEISA is a sustainable agribusiness system applying low external input. The system was developed in the framework of optimizing local-based productive resources including soil, water, vegetation, microclimate, renewable energy, appropriate technology, social capital, environment and human resources by combining various subsystems including integrated production subsystems of crops, livestock and fish to provide a maximum synergy effect, post-harvest subsystem and processing of results, marketing subsystems and supporting subsystems. In this study, the ecological boundary of Cipunegara sub-watershed ecosystem, administrative boundaries are Surian Subdistricts in Sumedang. The purpose of this study are to identify the potency of natural resources and local agricultural technologies that could support the LEISA model in Surian and to identify the potency of internal and external inputs in the LEISA model. The research used qualitative descriptive method and technical action research. Data were obtained through interviews, documentation, and observation. The results showed that natural resources in the form of agricultural land, water resources, livestock resources, and human labor are sufficient to support agribusiness model of LEISA. LEISA agribusiness model that has been applied in the research location is the integration of beef cattle, agroforestry, and agrosilvopasture. By building LEISA model, agribusiness can optimize the utilization of locally based productive resources, reduce dependence on external resources, and support sustainable food security.

2016-06-01

In this article, we draw on current research to explore notions of socially just health and physical education (HPE) programs, in light of claims that a neoliberal globalization promotes markets over the states and a new individualism that privileges self-interest over the collective good. We also invite readers to consider the UN Educational, Scientific, and Cultural Organization's ambition for physical education in light of preliminary findings from an Australian-led research project exploring national and international patterns of outsourcing HPE curricula. Data were sourced from this international research project through a mixed-methods approach. Each external provider engaged in 4 phases of research activity: (a) Web audits, (b) interviews with external providers, (c) network diagrams, and (d) school partner interviews and observations. We then used these data to pose what we believe to be three emerging lines of inquiry and challenge for a socially just school HPE in neoliberal times. In particular, our data indicate that the marketization of school HPE is strengthening an emphasis on individual responsibility for personal health, thereby elevating expectations that schools and teachers will "fill the welfare gap" and, finally, influencing the nature and purchase of educative HPE programs in schools. The apparent proliferation of external providers of health work and HPE resources and services reflects the rise and pervasiveness of neoliberalism in education. We conclude that this global HPE landscape warrants attention to investigate the extent to which external providers' resources are compatible with schooling's educative and inclusive mandates.

Reactive aggression and peer victimization from pre-kindergarten to first grade: accounting for hyperactivity and teacher-child conflict.

PubMed

Runions, Kevin C

2014-12-01

The role of reactive aggression in the development of peer victimization remains unclear due in part to a failure to account for confounding problems of behavioural undercontrol (e.g., hyperactivity). As well, the school social context has rarely been examined to see whether these risks are mediated by relationships with teachers. This study tests the prospective relations between reactive aggression, hyperactivity, victimization, and teacher-child (T-C) relationship, to determine whether conflict mediates the relationships between externalizing problems and victimization. A sample of 1,114 Australian students were followed from pre-kindergarten through first grade. Cross-lagged path analyses were conducted, with comparison of gender-moderating models and autocorrelation models. Full-information maximum likelihood was deployed to account for missingness. Best fitting models found that the relationship of early externalizing problems to later victimization was mediated by T-C conflict. No evidence of victimization increasing externalizing problems nor gender differences were observed. T-C conflict in kindergarten predicted subsequent increases in victimization, reactive aggression, and hyperactivity. Understanding the processes whereby externalizing problems confer risk of victimization involves understanding the whole social context of classrooms, including relationships with teachers. Finer-grained research is needed to better understand how peer dynamics may be influenced by observation of T-C relationships. Pre-service teacher education needs to ensure a focus on the potential social impact of teacher's relationships with students. © 2014 The British Psychological Society.

Research suggests that genetic, prenatal, endocrine, and parenting influences across development individually contribute to internalizing and externalizing problems in children. The present study tests the combined contributions of genetic risk for psychopathology, prenatal environments (maternal drug use and internalizing symptoms), child cortisol at age 4.5 years, and overreactive parenting influences across childhood on 6-year-old children's internalizing and externalizing problems. We used data from an adoption design that included 361 domestically adopted children and their biological and adopted parents prospectively followed from birth. Only parenting influences contributed (independently) to externalizing problems. However, genetic influences were indirectly associated with internalizing problems (through increased prenatal risk and subsequent morning cortisol), and parenting factors were both directly and indirectly associated with internalizing problems (through morning cortisol). Results suggest that prenatal maternal drug use/symptoms and children's morning cortisol levels are mechanisms of genetic and environmental influences on internalizing problems, but not externalizing problems, in childhood.

Theory of Self- vs. Externally-Regulated LearningTM: Fundamentals, Evidence, and Applicability

PubMed Central

de la Fuente-Arias, Jesús

2017-01-01

The Theory of Self- vs. Externally-Regulated LearningTM has integrated the variables of SRL theory, the DEDEPRO model, and the 3P model. This new Theory has proposed: (a) in general, the importance of the cyclical model of individual self-regulation (SR) and of external regulation stemming from the context (ER), as two different and complementary variables, both in combination and in interaction; (b) specifically, in the teaching-learning context, the relevance of different types of combinations between levels of self-regulation (SR) and of external regulation (ER) in the prediction of self-regulated learning (SRL), and of cognitive-emotional achievement. This review analyzes the assumptions, conceptual elements, empirical evidence, benefits and limitations of SRL vs. ERL Theory. Finally, professional fields of application and future lines of research are suggested. PMID:29033872

Alcohol-related Genes Show an Enrichment of Associations with a Persistent Externalizing Factor

PubMed Central

Ashenhurst, James R.; Harden, K. Paige; Corbin, William R.; Fromme, Kim

2016-01-01

Research using twins has found that much of the variability in externalizing phenotypes – including alcohol and drug use, impulsive personality traits, risky sex and property crime – is explained by genetic factors. Nevertheless, identification of specific genes and variants associated with these traits has proven to be difficult, likely because individual differences in externalizing are explained by many genes of small individual effect. Moreover, twin research indicates that heritable variance in externalizing behaviors is mostly shared across the externalizing spectrum rather than specific to any behavior. We use a longitudinal, “deep phenotyping” approach to model a general externalizing factor reflecting persistent engagement in a variety of socially problematic behaviors measured at eleven assessment occasions spanning early adulthood (ages 18 to 28). In an ancestrally homogenous sample of non-Hispanic Whites (N = 337), we then tested for enrichment of associations between the persistent externalizing factor and a set of 3,281 polymorphisms within 104 genes that were previously identified as associated with alcohol-use behaviors. Next we tested for enrichment among domain-specific factors (e.g., property crime) composed of residual variance not accounted for by the common factor. Significance was determined relative to bootstrapped empirical thresholds derived from permutations of phenotypic data. Results indicated significant enrichment of genetic associations for persistent externalizing, but not for domain-specific factors. Consistent with twin research findings, these results suggest that genetic variants are broadly associated with externalizing behaviors rather than unique to specific behaviors. General Scientific Summary This study shows that variation in 104 genes is associated with socially problematic “externalizing” behavior, including substance misuse, property crime, risky sex, and aspects of impulsive personality. Importantly, this association was with the common variation across these behaviors rather than with the variation unique to any given behavior. The manuscript demonstrates a potentially advantageous technique for relating sets of hypothesized genes to complex traits or behaviors. PMID:27505405

2012-07-01

This study examined the mental health and academic functioning of 442 4- and 5-year old children of Mexican (MA) and Dominican (DA) immigrant mothers using a cultural framework of Latino parenting. Data were collected on mothers' self-reported acculturative status, parenting practices and cultural socialization, and on children's behavioral functioning (mother- and teacher-report) and school readiness (child test). Results provide partial support for the validity of the framework in which mothers' acculturative status and socialization of respeto (a Latino cultural value of respect) and independence (a U.S. American cultural value) predict parenting practices. For both groups, English language competence was related to less socialization of respeto, and other domains of acculturative status (i.e., U.S. American/ethnic identity, and U.S. American/ethnic cultural competence) were related to more socialization of respeto and independence. Socialization of respeto was related to the use of authoritarian practices and socialization of independence was related to the use of authoritative practices. Socialization of respeto was also related to lower school readiness for DA children, whereas socialization of independence was related to higher school readiness for MA children. Independence was also related to higher teacher-rated externalizing problems for MA children. For both groups, authoritarian parenting was associated with more parent-reported internalizing and externalizing problems. The discussion focuses on ethnic subgroup differences and similarities to further understanding of Latino parenting from a cultural perspective.

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.

PubMed

Starr, Kimberly; Conley, Virginia M

2006-01-01

Little is known about the perceptions of nursing students externing in newly developed hospital-based programs that focus on socialization and transition to the registered nurse (RN) role rather than on institutional recruitment and retention goals. This qualitative study explored student nurse externs' expectations, experiences, and benefits of participation in a student-focused externship program. Externs wanted to gain experience with skills and learn what it was like to be an RN. Goals were met or exceeded by becoming comfortable in the externship role, growing in skill performance and confidence, and becoming members of the healthcare team. The experience fostered growth from the novice to advanced beginner level of nursing practice. Externs saw the program participation as a valuable way to gain experience and learn what it was like to be an RN.

Application of DuPont photopolymer films to automotive holographic display

Automotive holographic head-up display (HUD) systems employing DuPont holographic photopolymer films are presented. Holographic materials for automotive application are exposed to severe environmental conditions and are required high performance. This paper describes the improvement of DuPont photopolymer films for the automotive use, critical technical issues such as optical design, external color and stray light. The holographic HUD combiner embedded in a windshield of an automobile has peculiar problems called external color. Diffraction light from holographic combiner makes its external color tone stimulative. We have introduced RGB three color recording and color simulation in order to improve the external color. A moderate external color tone was realized by the optimization in terms of wavelengths and diffraction efficiencies of the combiner hologram. The stray light called flare arises from a reflection by glass surface of windshield. We have developed two techniques to avoid the flare. First is a diffuser type trap beam guard hologram which reduces the intensity of the flare. Second is the optimization of the design of hologram so that the incident direction of flare is lower than the horizon line. As an example of automotive display a stand-alone type holographic HUD system attached on the dashboard of an automobile is demonstrated, which provides useful driving information such as route guidance. The display has a very simple optical system that consists of only a holographic combiner and a vacuum fluorescent display. Its thin body is only 35 mm high and does not obstruct driver's view. The display gives high contrast and wide image.

This research investigated whether parent-teacher relationship quality mediated the relation between parents' motivational beliefs and children's adaptive functioning and externalizing behaviors. The sample consisted of kindergarten through third-grade children with behavioral concerns (N=206). Parents reported on their motivational beliefs (i.e., role construction and efficacy), and teachers reported on the quality of their relationships with parents and children's adaptive functioning (i.e., social and adaptive skills) and externalizing behaviors. Results indicated that parents' motivational beliefs were related significantly and positively to children's adaptive functioning and negatively to children's externalizing behaviors. Parents' motivational beliefs were also significantly associated with enhanced parent-teacher relationship quality. There was a significant medium-sized indirect effect of parents' motivational beliefs on children's adaptive functioning through parent-teacher relationship quality (k(2)=.12) and a small indirect effect of parents' motivational beliefs on children's externalizing behaviors (k(2)=.05). This research suggests that parent-teacher relationship quality may be one mechanism by which the benefits of parents' motivational beliefs are transmitted to children.

Paquet, Y; Scoffier, S; d'Arripe-Longueville, F

2016-10-01

In the field of health psychology, the control has consistently been considered as a protective factor. This protective role has been also highlighted in eating attitudes' domain. However, current studies use the one-dimensional scale of Rotter or the multidimensional health locus of control scale, and no specific eating attitudes' scale in the sport context exists. Moreover, the social influence in previous scales is limited. According to recent works, the purpose of this study was to test the internal and external validity of a multidimensional locus of control scale of eating attitudes for athletes. One hundred and seventy-nine participants were solicited. A confirmatory factorial analysis was conducted in order to test the internal validity of the scale. The scale external validity was tested in relation to eating attitudes. The internal validity of the scale was verified as well as the external validity, which confirmed the importance of taking into consideration social influences. Indeed, the 2 subscales "Trainers, friends" and "Parents, family" are related respectively positively and negatively in eating disorders. Copyright © 2016 L'Encéphale, Paris.

Gated Community Housing develops rapidly in Medan City and other big cities in Indonesia. These housing types initially reserved for middle to high-income residents. Transformation can describe as changes from one condition to another condition that can happen continuously in time. Change is affected by internal and external factors. Internal factors include culture, perspective, and social system while external factors include science progress and other cultural influence. This research is a descriptive study which tries to describe the phenomenon that is currently ongoing. Gated housing chosen are Perumahan Taman Setia Budi Indah, Perumahan Bumi Asri dan Perumahan Graha Helvetia. Characteristics of gated housing’s residents transform by the regional or national socioeconomic transformation. The structure and function of human social life are not uniform; meaning in every social life setting each of the structure and function are different. The characteristic of a community will transform in continuity.

Black churches and HIV/AIDS: factors influencing congregations’ responsiveness to social issues.

PubMed

Fulton, Brad R

2011-01-01

The ambivalent response of many black churches to current social issues has caused some scholars to question the centrality of black churches within African-American communities. Using a nationally representative sample of black congregations, this study engages the debate about the institutional centrality of black churches by focusing on their response to HIV/AIDS. Although many congregational studies treat black churches as a monolithic whole, this analysis identifies heterogeneity among black churches that shapes their responsiveness to social issues. Contrary to prior claims, a congregation's liberal-conservative ideological orientation does not significantly affect its likelihood of having an HIV/AIDS program. Beyond assessing churches’ internal characteristics, this study uses institutional theory to analyze churches as open systems that can be influenced by their surrounding environment. It demonstrates that externally engaged congregations are significantly more likely to have a program. These results indicate that black churches maintain institutional centrality by engaging their external environment.

Sociology: a view from the diaspora.

PubMed

Rosenfeld, Richard

2010-12-01

From the vantage point of criminology, one of sociology's main export subject areas, the present and future of sociology appear a good deal more promising than John Holmwood's essay on the discipline's misfortune would suggest. Sociology remains in high demand by students and faculty hiring remains strong, even in its more critical sub-fields, such as race and ethnicity, sex and gender, and social inequality. Holmwood is correct that sociology is vulnerable to external pressures to demonstrate its relevance to social practice, but those pressures come from left-wing social movements as well as from centres of power. He is also correct that external pressures contribute to internal disagreement, but sociology has been at war with itself since the 1960s, with little evident decline in its academic standing or intellectual vitality. Those of us on the discipline's diaspora, who depend on sociology for both support and light, must remain hopeful about sociology's continued good fortune.

Replicable Facets of Positive Emotionality and Their Relations to Psychopathology.

PubMed

Stanton, Kasey; Watson, David

2015-12-01

General individual differences in positive emotionality are negatively related to depression, social anxiety, and schizotypy/schizophrenia, and positively related to mania. However, the structure of positive emotionality remains unclear at the facet level, as there are significant disparities in the types of content assessed across emotionality measures. This study analyzed the lower order structure of positive emotionality in two samples, finding evidence for a replicable two-factor structure of Joviality and Experience Seeking. These factors demonstrated a markedly different pattern of relations in both direction and magnitude with internalizing, externalizing, and schizotypal symptoms. Joviality seems to represent an adaptive variant of positive emotionality, as it showed strong positive relations with well-being and moderate negative relations with measures of depression, social anxiety, and social anhedonia. In contrast, Experience Seeking appears to be somewhat maladaptive. It generally related positively to psychopathology, correlating most strongly with indicators of manic and externalizing symptoms. © The Author(s) 2014.

Assessment of generalizability, applicability and predictability (GAP) for evaluating external validity in studies of universal family-based prevention of alcohol misuse in young people: systematic methodological review of randomized controlled trials.

2012-09-01

To assess external validity characteristics of studies from two Cochrane Systematic Reviews of the effectiveness of universal family-based prevention of alcohol misuse in young people. Two reviewers used an a priori developed external validity rating form and independently assessed three external validity dimensions of generalizability, applicability and predictability (GAP) in randomized controlled trials. The majority (69%) of the included 29 studies were rated 'unclear' on the reporting of sufficient information for judging generalizability from sample to study population. Ten studies (35%) were rated 'unclear' on the reporting of sufficient information for judging applicability to other populations and settings. No study provided an assessment of the validity of the trial end-point measures for subsequent mortality, morbidity, quality of life or other economic or social outcomes. Similarly, no study reported on the validity of surrogate measures using established criteria for assessing surrogate end-points. Studies evaluating the benefits of family-based prevention of alcohol misuse in young people are generally inadequate at reporting information relevant to generalizability of the findings or implications for health or social outcomes. Researchers, study authors, peer reviewers, journal editors and scientific societies should take steps to improve the reporting of information relevant to external validity in prevention trials. © 2012 The Authors.

Niche construction, social cognition, and language: hypothesizing the human as the production of place.

PubMed

Davies, Oliver

2016-01-01

New data is emerging from evolutionary anthropology and the neuroscience of social cognition on our species-specific hyper-cooperation (HC). This paper attempts an integration of third-person archaeological and second-person, neuroscientific perspectives on the structure of HC, through a post-Ricoeurian development in hermeneutical phenomenology. We argue for the relatively late evolution of advanced linguistic consciousness (ALC) (Hiscock in Biological Theory 9:27-41, 2014), as a reflexive system based on the 'in-between' or 'cognitive system' as reported by Vogeley et al. (in: Interdisziplinäre anthropologie, Heidelberg, Springer, 2014) of face-to-face social cognition, as well as tool use. The possibility of a positive or negative tension between the more recent ALC and the more ancient, pre-thematic, self-organizing 'in-between' frames an 'internal' niche construction. This indexes the internal structure of HC as 'convergence', where complex, engaged, social reasoning in ALC mirrors the cognitive structure of the pre-thematic 'in-between', extending the bio-energy of our social cognition, through reflexive amplification, in the production of 'social place' as 'humanized space'. If individual word/phrase acquisition, in contextual actuality, is the distinctive feature of human language (Hurford in European Reviews 12:551-565, 2004), then human language is a hyperbolic, species-wide training in particularized co-location, developing consciousness of a shared world. The humanization of space and production of HC, through co-location, requires the 'disarming' of language as a medium of control, and a foregrounding of the materiality of the sign. The production of 'hyper-place' as solidarity beyond the face-to-face, typical of world religions, becomes possible where internal niche construction as convergence with the 'in-between' (world in us) combines with religious cosmologies reflecting an external 'cosmic' niche construction (world outside us).

Functional mechanisms involved in the internal inhibition of taboo words.

The present study used functional magnetic resonance imaging to investigate brain processes associated with the inhibition of socially undesirable speech. It is tested whether the inhibition of undesirable speech is solely related to brain areas associated with classical stop signal tasks or rather also involves brain areas involved in endogenous self-control. During the experiment, subjects had to do a SLIP task, which was designed to elicit taboo or neutral spoonerisms. Here we show that the internal inhibition of taboo words activates the right inferior frontal gyrus, an area that has previously been associated with externally triggered inhibition. This finding strongly suggests that external social rules become internalized and act as a stop-signal.

2014-01-01

This article presents 2 studies testing Paulhus's (2002) assumption that unconscious self-enhancement and conscious impression management represent separate processes of socially desirable responding (SDR) that can be observed within 2 content domains (egoistic and moralistic bias). In Study 1, we devised egoistic and moralistic SDR scales intended to measure self-enhancement in honest responding and impression management under demands for positive self-presentation. In Study 2, we correlated scores on these scales with external indicators of self-enhancement and impression management. In honest responding, both SDR scales most strongly correlated with self-enhancement indicators, whereas under demands for positive self-presentation they correlated more strongly with external measures of impression management.

Efficient management of marine resources in conflict: an empirical study of marine sand mining, Korea.

PubMed

Kim, Tae-Goun

2009-10-01

This article develops a dynamic model of efficient use of exhaustible marine sand resources in the context of marine mining externalities. The classical Hotelling extraction model is applied to sand mining in Ongjin, Korea and extended to include the estimated marginal external costs that mining imposes on marine fisheries. The socially efficient sand extraction plan is compared with the extraction paths suggested by scientific research. If marginal environmental costs are correctly estimated, the developed efficient extraction plan considering the resource rent may increase the social welfare and reduce the conflicts among the marine sand resource users. The empirical results are interpreted with an emphasis on guidelines for coastal resource management policy.

Purpose: In this study, the adequacy of target expansions on the combined external beam and implant dose was examined based on the measured daily motion of the prostate. Methods: Thirty patients received an I–125 prostate implant prescribed to dose of 90Gy. This was followed by external beam to deliver a dose of 90Gyeq (external beam equivalent) to the prostate over 25 to 30 fractions. An ideal IMRT plan was developed by optimizing the external beam dose based on the delivered implant dose. The implant dose was converted to an equivalent external beam dose using the linear quadratic model. Patients weremore » set up on the treatment table by daily orthogonal imaging and aligning the marker seeds in the prostate. Orthogonal images were obtained at the end of treatment to assess prostate intrafraction motion. Based on the observed motion of the markers between the initial and final images, 5 individual plans showing the actual dose delivered to the patient were calculated. A final true dose distribution was established based on summing the implant dose and the 5 external beam plans. Dose to the prostate, seminal vesicles, lymphnodes and normal tissues, rectal wall, urethra and lower sphincter were calculated and compared to ideal. On 18 patients who were sexually active, dose to the corpus cavernosum and internal pudendal artery was also calculated. Results: The average prostate motion in 3 orthogonal directions was less than 1 mm with a standard deviation of less than +2 mm. Dose and volume parameters showed that there was no decrease in dose to the targets and a marginal decrease in dose to in normal tissues. Conclusion: Dose delivered by seed implant moves with the prostate, decreasing the impact of intrafractions dose movement on actual dose delivered. Combined brachytherapy and external beam dose delivered to the prostate was not sensitive to prostate motion.« less

Effects of internal and external environment on health and well-being: from cell to society.

PubMed

Tomljenović, Andrea

2014-03-01

Stem cell fate in cell culture depends on the composition of the culturing media. Every single cell in an organism is influenced by its microenvironment and surrounding cells. Biology, psychology, emotions, spirit, energy, lifestyle, culture, economic and political influences, social interactions in family, work, living area and the possibilities to expresses oneself and live full life with a sense of well-being have influence on people appearances. Disease is as much social as biological. It is a reaction of an organism to unbalancing changes in the internal environment caused by the changes in the external environment and/or by the structural and functional failures or unfortunate legacies. Health gradient in the society depends on the every day circumstances in which people live and work. The health of the population is an insight into the society. The problem facing medicine in the complex society of today cannot be resolved without the aid of social sciences, as cultural, social, ecological and mental processes affect physiological responses and health outcomes. Anthropology could be a bridge between biomedicine and social sciences and influence strategies in public health to prevent rather than cure and in education for fulfillment in life and improvement of society.

Mexican American adolescents have higher rates of externalizing problems than their peers from other ethnic and racial groups. To begin the process of understanding factors related to externalizing problems in this population, this study used the Social Development Model and prospective data across the transition to junior high school from 750 diverse Mexican American families. In addition, we examined whether familism values provided a protective effect for relations within the model. Results showed that the SDM worked well for this sample. As expected, association with deviant peers was the primary predictor of externalizing behaviors. There was support for a protective effect in that adolescents with higher familism values had slower rates of increase in association with deviant peers from 5th to 7th grades than those with lower familism values. Future research needs to determine whether additional culturally appropriate modifications of the SDM would increase its usefulness for Mexican American adolescents. PMID:21142368

Adults with severe traumatic brain injury (TBI) often suffer poor social cognition. Social cognition is complex, requiring verbal, non-verbal, auditory, visual and affective input and integration. While damage to focal temporal and frontal areas has been implicated in disorders of social cognition after TBI, the role of white matter pathology has not been examined. In this study 17 adults with chronic, severe TBI and 17 control participants underwent structural MRI scans and Diffusion Tensor Imaging. The Awareness of Social Inference Test (TASIT) was used to assess their ability to understand emotional states, thoughts, intentions and conversational meaning in everyday exchanges. Track-based spatial statistics were used to perform voxelwise analysis of Fractional Anisotropy (FA) and Mean Diffusivity (MD) of white matter tracts associated with poor social cognitive performance. FA suggested a wide range of tracts were implicated in poor TASIT performance including tracts known to mediate, auditory localisation (planum temporale) communication between nonverbal and verbal processes in general (corpus callosum) and in memory in particular (fornix) as well as tracts and structures associated with semantics and verbal recall (left temporal lobe and hippocampus), multimodal processing and integration (thalamus, external capsule, cerebellum) and with social cognition (orbitofrontal cortex, frontopolar cortex, right temporal lobe). Even when controlling for non-social cognition, the corpus callosum, fornix, bilateral thalamus, right external capsule and right temporal lobe remained significant contributors to social cognitive performance. This study highlights the importance of loss of white matter connectivity in producing complex social information processing deficits after TBI.

Automated external defibrillators are pervasive computing devices designed for the treatment and management of acute sudden cardiac arrest. This study aims to explain users' actual use behavior in teams formed by different professions taken after a short time span of interaction with automated external defibrillator. Before the intervention, all the participants were certified with the American Heart Association Basic Life Support for healthcare providers. A statistically significant difference was revealed in mean individual automated external defibrillator technical skills between uniprofessional and interprofessional groups. The technical automated external defibrillator team scores were greater for groups with interprofessional than for those with uniprofessional education. The nontechnical automated external defibrillator skills of interprofessional and uniprofessional teams revealed differences in advantage of interprofessional teams. Students positively accept automated external defibrillators if well-defined and validated training opportunities to use them expertly are available. Uniprofessional teams were successfully supported by their members and, thereby, used automated external defibrillator effectively. Furthermore, the interprofessional approach resulted in as much effective teamwork as the uniprofessional approach.

Improving external beam radiotherapy by combination with internal irradiation.

PubMed

Dietrich, A; Koi, L; Zöphel, K; Sihver, W; Kotzerke, J; Baumann, M; Krause, M

2015-07-01

The efficacy of external beam radiotherapy (EBRT) is dose dependent, but the dose that can be applied to solid tumour lesions is limited by the sensitivity of the surrounding tissue. The combination of EBRT with systemically applied radioimmunotherapy (RIT) is a promising approach to increase efficacy of radiotherapy. Toxicities of both treatment modalities of this combination of internal and external radiotherapy (CIERT) are not additive, as different organs at risk are in target. However, advantages of both single treatments are combined, for example, precise high dose delivery to the bulk tumour via standard EBRT, which can be increased by addition of RIT, and potential targeting of micrometastases by RIT. Eventually, theragnostic radionuclide pairs can be used to predict uptake of the radiotherapeutic drug prior to and during therapy and find individual patients who may benefit from this treatment. This review aims to highlight the outcome of pre-clinical studies on CIERT and resultant questions for translation into the clinic. Few clinical data are available until now and reasons as well as challenges for clinical implementation are discussed.

Mercury risk assessment combining internal and external exposure methods for a population living near a municipal solid waste incinerator.

Risk assessments for human health have been conducted for municipal solid waste incinerators (MSWIs) in many western countries, whereas only a few risk assessments have been performed for MSWIs in developing countries such as China where the use of waste incineration is increasing rapidly. To assess the mercury exposure risks of a population living near the largest MSWI in South China, we combined internal exposure and external exposure assessment with an individual-specific questionnaire. The mercury concentrations in air, soil, and locally collected food around the MSWI were assessed. The total mercury (T-Hg) and methylmercury (MeHg) of 447 blood samples from a control group, residential exposure group, and MSWI workers were measured. The internal and external exposures of the subject population were analyzed. Significant difference in MeHg concentrations was observed between the control group and the exposed group, between the control group and the MSWI workers, and between the exposed group and the MSWI workers (median levels: 0.70 μg/L, 0.81 μg/L, and 1.02 μg/L for the control group, exposed group, and MSWI workers, respectively). The MeHg/T-Hg ratio was 0.51 ± 0.19, 0.59 ± 0.17 and 0.58 ± 0.25, respectively. Multiple linear regression analysis indicated that MeHg concentrations were positively correlated with the gaseous mercury in the air. Combining internal and external exposure assessment showed that the direct contribution of MSWI emissions was minor compared with the dietary contribution. The external and internal exposures were well matched with each other. This study also suggested that an integrated method combining internal and external exposure assessment with an individual-specific questionnaire is feasible to assess the risks for a population living near a MSWI.

A hypothesis on the biological origins and social evolution of music and dance.

PubMed

Wang, Tianyan

2015-01-01

The origins of music and musical emotions is still an enigma, here I propose a comprehensive hypothesis on the origins and evolution of music, dance, and speech from a biological and sociological perspective. I suggest that every pitch interval between neighboring notes in music represents corresponding movement pattern through interpreting the Doppler effect of sound, which not only provides a possible explanation for the transposition invariance of music, but also integrates music and dance into a common form-rhythmic movements. Accordingly, investigating the origins of music poses the question: why do humans appreciate rhythmic movements? I suggest that human appreciation of rhythmic movements and rhythmic events developed from the natural selection of organisms adapting to the internal and external rhythmic environments. The perception and production of, as well as synchronization with external and internal rhythms are so vital for an organism's survival and reproduction, that animals have a rhythm-related reward and emotion (RRRE) system. The RRRE system enables the appreciation of rhythmic movements and events, and is integral to the origination of music, dance and speech. The first type of rewards and emotions (rhythm-related rewards and emotions, RRREs) are evoked by music and dance, and have biological and social functions, which in turn, promote the evolution of music, dance and speech. These functions also evoke a second type of rewards and emotions, which I name society-related rewards and emotions (SRREs). The neural circuits of RRREs and SRREs develop in species formation and personal growth, with congenital and acquired characteristics, respectively, namely music is the combination of nature and culture. This hypothesis provides probable selection pressures and outlines the evolution of music, dance, and speech. The links between the Doppler effect and the RRREs and SRREs can be empirically tested, making the current hypothesis scientifically concrete.

Automatic online and real-time tumour motion monitoring during stereotactic liver treatments on a conventional linac by combined optical and sparse monoscopic imaging with kilovoltage x-rays (COSMIK)

The purpose of this study was to develop, validate and clinically demonstrate fully automatic tumour motion monitoring on a conventional linear accelerator by combined optical and sparse monoscopic imaging with kilovoltage x-rays (COSMIK). COSMIK combines auto-segmentation of implanted fiducial markers in cone-beam computed tomography (CBCT) projections and intra-treatment kV images with simultaneous streaming of an external motion signal. A pre-treatment CBCT is acquired with simultaneous recording of the motion of an external marker block on the abdomen. The 3-dimensional (3D) marker motion during the CBCT is estimated from the auto-segmented positions in the projections and used to optimize an external correlation model (ECM) of internal motion as a function of external motion. During treatment, the ECM estimates the internal motion from the external motion at 20 Hz. KV images are acquired every 3 s, auto-segmented, and used to update the ECM for baseline shifts between internal and external motion. The COSMIK method was validated using Calypso-recorded internal tumour motion with simultaneous camera-recorded external motion for 15 liver stereotactic body radiotherapy (SBRT) patients. The validation included phantom experiments and simulations hereof for 12 fractions and further simulations for 42 fractions. The simulations compared the accuracy of COSMIK with ECM-based monitoring without model updates and with model updates based on stereoscopic imaging as well as continuous kilovoltage intrafraction monitoring (KIM) at 10 Hz without an external signal. Clinical real-time tumour motion monitoring with COSMIK was performed offline for 14 liver SBRT patients (41 fractions) and online for one patient (two fractions). The mean 3D root-mean-square error for the four monitoring methods was 1.61 mm (COSMIK), 2.31 mm (ECM without updates), 1.49 mm (ECM with stereoscopic updates) and 0.75 mm (KIM). COSMIK is the first combined kV/optical real-time motion monitoring method used clinically online on a conventional accelerator. COSMIK gives less imaging dose than KIM and is in addition applicable when the kV imager cannot be deployed such as during non-coplanar fields.

Eating behaviors and weight over time in a prospective study: the Healthy Twin Study.

PubMed

Song, Yun-Mi; Lee, Kayoung; Sung, Joohon

2014-01-01

We examined the relationships of combined initial restrained and external/emotional eating with initial BMI and change in weight and these subscales over time. BMI and the Dutch Eating Behavior Questionnaire were twicemeasured in 1361 Korean twins and families (482 men, 879 women) over a period of 2.7±0.9 years. Subjects were classified by combination of initial sex-specific restrained and external (or emotional) eating tertiles. Linear mixed models were performed after adjusting for confounders at baseline (household, sibling relations, sex, age, education level, smoking, alcohol use, energy intake, physical activity, and medical history). In adjusted models, initial BMI increased with increasing tertiles of initial restrained eating across initial external/emotional eating tertiles. Weight was less likely to increase over time with increasing tertiles of initial restrained eating in the lowest external eating tertile and middle tertile of emotional eating at baseline. Subscale scores decreased over time with increasing tertiles of corresponding subscales at baseline. These findings suggest that high dietary restraint and external/emotional eating may indicate concurrent high BMI and attenuated weight gain and decreases in corresponding subscales over time.

A Model of Human Cooperation in Social Dilemmas

PubMed Central

Capraro, Valerio

2013-01-01

Social dilemmas are situations in which collective interests are at odds with private interests: pollution, depletion of natural resources, and intergroup conflicts, are at their core social dilemmas. Because of their multidisciplinarity and their importance, social dilemmas have been studied by economists, biologists, psychologists, sociologists, and political scientists. These studies typically explain tendency to cooperation by dividing people in proself and prosocial types, or appealing to forms of external control or, in iterated social dilemmas, to long-term strategies. But recent experiments have shown that cooperation is possible even in one-shot social dilemmas without forms of external control and the rate of cooperation typically depends on the payoffs. This makes impossible a predictive division between proself and prosocial people and proves that people have attitude to cooperation by nature. The key innovation of this article is in fact to postulate that humans have attitude to cooperation by nature and consequently they do not act a priori as single agents, as assumed by standard economic models, but they forecast how a social dilemma would evolve if they formed coalitions and then they act according to their most optimistic forecast. Formalizing this idea we propose the first predictive model of human cooperation able to organize a number of different experimental findings that are not explained by the standard model. We show also that the model makes satisfactorily accurate quantitative predictions of population average behavior in one-shot social dilemmas. PMID:24009679

Calzada, Esther J.; Huang, Keng-Yen; Anicama, Catherine; Fernandez, Yenny; Brotman, Laurie Miller

2015-01-01

This study examined the mental health and academic functioning of 442 4- and 5-year old children of Mexican (MA) and Dominican (DA) immigrant mothers using a cultural framework of Latino parenting. Data were collected on mothers' self-reported acculturative status, parenting practices and cultural socialization, and on children's behavioral functioning (mother- and teacher-report) and school readiness (child test). Results provide partial support for the validity of the framework in which mothers' acculturative status and socialization of respeto (a Latino cultural value of respect) and independence (a U.S. American cultural value) predict parenting practices. For both groups, English language competence was related to less socialization of respeto, and other domains of acculturative status (i.e., U.S. American/ethnic identity, and U.S. American/ethnic cultural competence) were related to more socialization of respeto and independence. Socialization of respeto was related to the use of authoritarian practices and socialization of independence was related to the use of authoritative practices. Socialization of respeto was also related to lower school readiness for DA children, whereas socialization of independence was related to higher school readiness for MA children. Independence was also related to higher teacher-rated externalizing problems for MA children. For both groups, authoritarian parenting was associated with more parent-reported internalizing and externalizing problems. The discussion focuses on ethnic subgroup differences and similarities to further understanding of Latino parenting from a cultural perspective. PMID:22686147

2017-06-19

Purpose The purpose of this paper is to explore work motivation among professionals at well-functioning primary healthcare centers subject to a national healthcare reform which include financial incentives. Design/methodology/approach Five primary healthcare centers in Sweden were purposively selected for being well-operated and representing public/private and small/large units. In total, 43 interviews were completed with different medical professions and qualitative deductive content analysis was conducted. Findings Work motivation exists for professionals when their individual goals are aligned with the organizational goals and the design of the reform. The centers' positive management was due to a unique combination of factors, such as clear direction of goals, a culture of non-hierarchical collaboration, and systematic quality improvement work. The financial incentives need to be translated in terms of quality patient care to provide clear direction for the professionals. Social processes where professionals work together as cohesive groups, and provided space for quality improvement work is pivotal in addressing how alignment is created. Practical implications Leaders need to consistently translate and integrate reforms with the professionals' drives and values. This is done by encouraging participation through teamwork, time for structured reflection, and quality improvement work. Social implications The design of the reforms and leadership are essential preconditions for work motivation. Originality/value The study offers a more complete picture of how reforms are managed at primary healthcare centers, as different medical professionals are included. The value also consists of showing how a range of aspects combine for primary healthcare professionals to successfully manage external reforms.

International Institutions and Domestic Reform: Equal Pay and British Membership in the European Economic Community.

PubMed

Frader, Laura Levine

2018-03-01

Despite having been overlooked in the standard histories of the UK and the European Community, gender politics and gender policies played a significant role in Britain's applications for membership in the EEC in the 1960s. Joining the European Community required that Britain comply with Article 119 on equal pay for equal work. A combination of domestic feminist and labour movement activism, the commitment of unions and parties, and the internationalization of formal commitments to women's rights constituted internal and external pressures for the passage of an Equal Pay Act in 1970. The article argues that the formal legislative commitment to gender pay equality, changing public attitudes towards women's employment, and European membership impacted further domestic social policy reform and slowly began to shift government attitudes towards gender equality.

To investigate the application and effect of minimally invasive percutaneous anterior pelvic pubic ramus screw fixation in Tile B fractures. A retrospective review was conducted on 56 patients with posterior pelvic ring injury combined with fractures of anterior pubic and ischiadic ramus treated between May 2010 and August 2015, including 31 males and 25 females with an average age of 36.8 years old ranging from 35 to 65 years old. Based on the Tile classification, there were 13 cases of Tile B1 type, 28 cases of Tile B2 type and 15 cases of Tile B3 type. Among them, 26 patients were treated with sacroiliac screws combined with external fixation (external fixator group) and the other 30 patients underwent sacroiliac screw fixation combined with anterior screw fixation (pubic ramus screw group). Postoperative complications, postoperative ambulation time, fracture healing, blood loss, Majeed pelvic function score and visual analogue scale(VAS) were compared between two groups. Fifty-four patients were followed up from 3 to 24 months with a mean of 12 months. There were no significant difference in the peri-operative bleeding and operation time between two groups( P >0.05). The postoperative activity time and fracture healing time of pubic ramus screw group were shorter than those of the external fixator group, the differences were statistically significant( P <0.05). The Majeed score, VAS score of pubic ramus screw group were higher than those of the external fixator group, the differences were statistically significant( P <0.05). The incidence of postoperative complications of pubic ramus screw was lower than that of the external fixator group, the difference was statistically significant ( P <0.05). Percutaneous iliosacral screws fixation combined with the pubic ramus screw is an effective and safty treatment method to the Tile B pelvic fracture. It has advantages of early ambulation, relief of the pain and few complications.

Childhood Internalizing and Externalizing Problems Predict the Onset of Clinical Panic Attacks over Adolescence: The TRAILS Study

PubMed Central

Mathyssek, Christina M.; Olino, Thomas M.; Verhulst, Frank C.; van Oort, Floor V. A.

2012-01-01

Background Panic attacks are a source of individual suffering and are an independent risk factor for later psychopathology. However, much less is known about risk factors for the development of panic attacks, particularly during adolescence when the incidence of panic attacks increases dramatically. We examined whether internalizing and externalizing problems in childhood predict the onset of panic attacks in adolescence. Method This study is part of the TRacking Adolescents’ Individual Lives Survey (TRAILS), a Dutch longitudinal population cohort study (N = 1,584). Internalizing and Externalizing Problems were collected using the Youth Self-Report (YSR) and the parent-report Child Behavior Checklist (CBCL) at baseline (age 10–12). At age 18–20, DSM-IV defined panic attacks since baseline were assessed with the Composite International Diagnostic Interview (CIDI). We investigated whether early adolescent Internalizing and Externalizing Problems predicted panic attacks between ages 10–20 years, using survival analysis in univariate and multivariate models. Results There were N = 314 (19.8%) cases who experienced at least one DSM-IV defined panic attack during adolescence and N = 18 (1.2%) who developed panic disorder during adolescence. In univariate analyses, CBCL Total Problems, Internalizing Problems and three of the eight syndrome scales predicted panic attack onset, while on the YSR all broad-band problem scales and each narrow-band syndrome scale predicted panic attack onset. In multivariate analyses, CBCL Social Problems (HR 1.19, p<.05), and YSR Thought Problems (HR 1.15, p<.05) and Social Problems (HR 1.26, p<.01) predicted panic attack onset. Conclusion Risk indicators of panic attack include the wide range of internalizing and externalizing problems. Yet, when adjusted for co-occurring problem behaviors, Social Problems were the most consistent risk factor for panic attack onsets in adolescence. PMID:23251576

To evaluate the use of external fixation of the humerus after missile injuries. Retrospective. University medical center. Twenty-six soldiers with twenty-six open Gustilo type III fractures. Immediate external fixation. Clinical, functional, social, and rehabilitation criteria were evaluated. Excellent in fourteen patients (61%), good in four (17%), fair in three (13%), and poor in two (9%). All fractures eventually healed. External fixation is the preferred initial treatment for stabilizing severe open missile fractures of the humerus. Its use, together with radical debridement of dead bone, has reduced the incidence of chronic infection and improved the prognosis of vascular repairs. As a result, the rate of morbidity and upper limb amputation has been reduced significantly, compared with our previous experience.

Social Worker Identity: A Profession in Context.

PubMed

Forenza, Brad; Eckert, Caitlin

2018-01-01

Social work is a broad field encompassing micro, mezzo, and macro areas of practice. Consequently, the field lacks a unifying professional identity due to the expansiveness of the profession. Professional identity is conceptualized as an extension of social identity, vis-à-vis the embodiment of three qualities: connectedness, expansiveness, and effectiveness. This study used 12 in-depth, individual interviews with practicing social workers to explore these qualities. Findings from interviews reveal six primary themes and 21 subthemes pertaining to social worker identity. Themes and subthemes are organized according to three broad families (social work in context, professional trajectories, and external influences). Implications for policy, practice, and future research are presented. © 2017 National Association of Social Workers.

Singled out by statistics as the third leading cause of mortality in our country, external causes (accidents and violence) entail a great impact with economic, social and emotional rebound. Knowing the factors related to the event is essential, because it allows identifying and breaking the web that determines morbidity and mortality from external causes. The study aims to analyze the existing publications on the factors associated with accidents and violence, in order to provide theoretical support for professionals in their practices. This is a bibliographical study of the Liliacs, Medline and Scielo databanks.

Bosco, Susan M

2002-12-01

Research on the career decision processes of women has focused primarily on internal considerations such as mathematical ability, intelligence, and self-esteem; however, the external environment also has an influence on these processes. To date, the environmental factors have primarily been researched separately, if at all. They include government policies, industry/economics, social trends/expected sex roles, and educational opportunities. This pilot study investigated these four external factors simultaneously. In addition, a survey of literature on career decision indicated such research to be based on a limited pool of highly educated, management/professional women. This study also uses a wider group including housewives, blue collar, and pink collar women.

Do African American mothers really "love" their sons and "raise" their daughters?

PubMed

Mandara, Jelani; Varner, Fatima; Richman, Scott

2010-02-01

This study assessed 1500 adolescents from the National Longitudinal Study of Youth to test the hypothesis that African American mothers differentially socialize their girls and boys. The results showed that later-born boys had fewer chores, argued more with their mothers, lived in less cognitively stimulating homes, and were not allowed to make the same decisions as were the girls or firstborn boys at the same age. The later-born boys were also lowest in achievement and highest in externalizing behaviors. Parenting differences accounted for the achievement differences but not for the externalizing behavior differences. It was concluded that the later-born boys would achieve at the same rates as their siblings if they were socialized in the same manner as their siblings.

Computer-mediated communication and time pressure induce higher cardiovascular responses in the preparatory and execution phases of cooperative tasks.

Costa Ferrer, Raquel; Serrano Rosa, Miguel Ángel; Zornoza Abad, Ana; Salvador Fernández-Montejo, Alicia

2010-11-01

The cardiovascular (CV) response to social challenge and stress is associated with the etiology of cardiovascular diseases. New ways of communication, time pressure and different types of information are common in our society. In this study, the cardiovascular response to two different tasks (open vs. closed information) was examined employing different communication channels (computer-mediated vs. face-to-face) and with different pace control (self vs. external). Our results indicate that there was a higher CV response in the computer-mediated condition, on the closed information task and in the externally paced condition. These role of these factors should be considered when studying the consequences of social stress and their underlying mechanisms.

Latent profiles of problem behavior within learning, peer, and teacher contexts: identifying subgroups of children at academic risk across the preschool year.

Bulotsky-Shearer, Rebecca J; Bell, Elizabeth R; Domínguez, Ximena

2012-12-01

Employing a developmental and ecological model, the study identified initial levels and rates of change in academic skills for subgroups of preschool children exhibiting problem behavior within routine classroom situations. Six distinct latent profile types of emotional and behavioral adjustment were identified for a cohort of low-income children early in the preschool year (N=4417). Profile types provided a descriptive picture of patterns of classroom externalizing, internalizing, and situational adjustment problems common to subgroups of children early in the preschool year. The largest profile type included children who exhibited low problem behavior and were characterized as well-adjusted to the preschool classroom early in the year. The other profile types were characterized by distinct combinations of elevated internalizing, externalizing, and situational problem behavior. Multinomial logistic regression identified younger children and boys at increased risk for classification in problem types, relative to the well-adjusted type. Latent growth models indicated that children classified within the extremely socially and academically disengaged profile type, started and ended the year with the lowest academic skills, relative to all other types. Implications for future research, policy, and practice are discussed. Copyright © 2012 Society for the Study of School Psychology. Published by Elsevier Ltd. All rights reserved.

Music Preferences, Friendship, and Externalizing Behavior in Early Adolescence: A SIENA Examination of the Music Marker Theory Using the SNARE Study.

PubMed

Franken, Aart; Keijsers, Loes; Dijkstra, Jan Kornelis; Ter Bogt, Tom

2017-08-01

Music Marker Theory posits that music is relevant for the structuring of peer groups and that rock, urban, or dance music preferences relate to externalizing behavior. The present study tested these hypotheses, by investigating the role of music preference similarity in friendship selection and the development of externalizing behavior, while taking the effects of friends' externalizing behavior into account. Data were used from the first three waves of the SNARE (Social Network Analysis of Risk behavior in Early adolescence) study (N = 1144; 50% boys; M age  = 12.7; SD = 0.47), including students who entered the first-year of secondary school. Two hypotheses were tested. First, adolescents were expected to select friends based both on a similarity in externalizing behavior and music genre preference. Second, a preference for rock, urban, or dance, music types was expected to predict the development of externalizing behavior, even when taking friends' influence on externalizing behavior into account. Stochastic Actor-Based Modeling indicated that adolescents select their friends based on both externalizing behavior and highbrow music preference. Moreover, both friends' externalizing behavior and a preference for dance music predicted the development of externalizing behavior. Intervention programs might focus on adolescents with dance music preferences.

While studies suggest that nutritional supplementation may reduce aggressive behavior in children, few have examined their effects on specific forms of aggression. This study tests the primary hypothesis that omega-3 (ω-3), both alone and in conjunction with social skills training, will have particular post-treatment efficacy for reducing childhood reactive aggression relative to baseline. In this randomized, double-blind, stratified, placebo-controlled, factorial trial, a clinical sample of 282 children with externalizing behavior aged 7-16 years was randomized into ω-3 only, social skills only, ω-3 + social skills, and placebo control groups. Treatment duration was 6 months. The primary outcome measure was reactive aggression collected at 0, 3, 6, 9, and 12 months, with antisocial behavior as a secondary outcome. Children in the ω-3-only group showed a short-term reduction (at 3 and 6 months) in self-report reactive aggression, and also a short-term reduction in overall antisocial behavior. Sensitivity analyses and a robustness check replicated significant interaction effects. Effect sizes (d) were small, ranging from 0.17 to 0.31. Findings provide some initial support for the efficacy of ω-3 in reducing reactive aggression over and above standard care (medication and parent training), but yield only preliminary and limited support for the efficacy of ω-3 in reducing overall externalizing behavior in children. Future studies could test further whether ω-3 shows promise in reducing more reactive, impulsive forms of aggression.

Latent profile analysis of sixth graders based on teacher ratings: Association with school dropout.

2015-12-01

The goal of this study was to identify meaningful groups of sixth graders with common characteristics based on teacher ratings of assets and maladaptive behaviors, describe dropout rates for each group, and examine the validity of these groups using students' self-reports. The sample consisted of racially diverse students (n = 675) attending sixth grade in public schools in Northeast Georgia. The majority of the sample was randomly selected; a smaller group was identified by teachers as high risk for aggression. Based on teacher ratings of externalizing behaviors, internalizing problems, academic skills, leadership, and social assets, latent profile analysis yielded 7 classes that can be displayed along a continuum: Well-Adapted, Average, Average-Social Skills Deficit, Internalizing, Externalizing, Disruptive Behavior with School Problems, and Severe Problems. Dropout rate was lowest for the Well-adapted class (4%) and highest for the Severe Problems class (58%). However, students in the Average-Social Skills Deficit class did not follow the continuum, with a large proportion of students who abandoned high school (29%). The proportion of students identified by teachers as high in aggression consistently increased across the continuum from none in the Well-Adapted class to 84% in the Severe Problems class. Students' self-reports were generally consistent with the latent profile classes. Students in the Well-Adapted class reported low aggression, drug use, and delinquency, and high life satisfaction; self-reports went in the opposite direction for the Disruptive Behaviors with School Problems class. Results highlight the importance of early interventions to improve academic performance, reduce externalizing behaviors, and enhance social assets. (c) 2015 APA, all rights reserved).

Patterns of Adolescent Bullying Behaviors: Physical, Verbal, Exclusion, Rumor, and Cyber

2012-01-01

Patterns of engagement in cyber bullying and four types of traditional bullying were examined using latent class analysis (LCA). Demographic differences and externalizing problems were evaluated across latent class membership. Data were obtained from the 2005–2006 Health Behavior in School-aged Survey and the analytic sample included 7,508 U.S. adolescents in grades 6 through 10. LCA models were tested on physical bullying, verbal bullying, social exclusion, spreading rumors, and cyber bullying behaviors. Three latent classes were identified for each gender: All-Types Bullies (10.5% for boys and 4.0% for girls), Verbal/Social Bullies (29.3% for boys and 29.4% for girls), and a Non-Involved class (60.2% for boys and 66.6% for girls). Boys were more likely to be All-Types Bullies than girls. The prevalence rates of All-Types and Verbal/Social Bullies peaked during grades 6 to 8 and grades 7 & 8, respectively. Pairwise comparisons across the three latent classes on externalizing problems were conducted. Overall, the All-Types Bullies were at highest risk of using substances and carrying weapons, the Non-Involved were at lowest risk, and the Verbal/Social Bullies were in the middle. Results also suggest that most cyber bullies belong to a group of highly aggressive adolescents who conduct all types of bullying. This finding does not only improve our understanding of the relation between cyber bullying and traditional bullying, but it also suggests that prevention and intervention efforts could target cyber bullies as a high-risk group for elevated externalizing problems.

Environmental externalities: Thinking globally, taxing locally

1993-03-01

Assigning monetary externality values to the airborne emissions of electric power plants is gaining the attention of state utility commissions as a means to measure the social costs of alternative energy investments. Some commissions are using environmental externalities to encourage utility investments in energy conservation and renewable energy technologies such as solar, wind, and biomass. However, the monetization of externalities through so-called adders to direct generation costs can lead to inefficient resource allocation and expose consumers to electric rate increases without corresponding environmental benefits. The addition of externality values to direct electric generation costs distorts the economics of power supplymore » planning by creating artificial subsidies for generation sources that are not currently competitive in the market. Businesses and consumers will be forced to support higher-cost sources of electric generation as a consequence. Because pollutant emissions of all new sources of electric generation are stringently regulated, and generally are well below those of existing fossil-fired sources, little demonstrable environmental benefit would result from the expanded use of externality valuation.« less

The purpose of this study was to assess the association of positive and negative parenting with child externalizing problems. Quantitative data were collected during face-to-face interviews with 320 parents of children 9–16 years of age (50% males) in 11 communities in Eastern, Southern and Central Ukraine. The study estimated the relationship between parenting practices and child externalizing behaviors, such as aggression, delinquency and attention problems. Results revealed that positive parenting, child monitoring, and avoidance of corporal punishment were associated with fewer child externalizing symptoms. Results also indicated that child male gender and single parenting had significant and positive association with child externalizing behaviors. This study extends international psychosocial knowledge on children and families. These findings can be used to design programs and foster dialogues about the role of family and social environments in the development of externalizing disorder among researchers, representatives of governmental and non-governmental organizations and mass media that work with child abuse prevention in Ukraine.

The purpose of this study was to examine how selected internal and external control variables influence lifetime use, frequency of use, and cessation of use of marijuana. The internal control factor, comprising the variables 1) perceived risk of marijuana use and 2) attitudes toward prohibition of marijuana use, refers to a built-in personal tendency toward conventionality. The external control factor refers to social-environmental forces which discourage marijuana use. External control is indicated by factors including the number of extra-curricular activities in which an individual is involved; place of residence; the availability of marijuana; peer attitudes toward marijuana use; the number of an individual's friends who use marijuana; and the number of occasions on which an individual has observed others using marijuana. The study's results show that both internal and external control factors are significant predictors of the frequency of marijuana use. The external control factor, however, plays a more important role in explaining lifetime marijuana use and cessation of marijuana use.

2016-05-18

To describe minimally-invasive lag screw osteosynthesis combined with external coaptation for the treatment of Salter-Harris type II third metacarpal and third metatarsal bone fractures. Three foals aged two weeks to four months with a Salter-Harris type II third metacarpal or third metatarsal fracture. Surgery was carried out under general anaesthesia in lateral recumbency. After fracture reduction, the metaphyseal fragment was stabilized with two cortical screws placed in lag fashion under fluoroscopic control. A cast was applied for at least two weeks. All foals had a good outcome with complete fracture healing and return to complete soundness without any angular limb deformity. All foals had moderate transient digital hyperextension after cast removal. Internal fixation of Salter-Harris type II third metacarpal or third metatarsal fractures with two cortical screws in lag fashion, combined with external coaptation provided good stabilization and preserved the longitudinal growth potential of the injured physis.

Hadronic Lorentz violation in chiral perturbation theory including the coupling to external fields

NASA Astrophysics Data System (ADS)

Kamand, Rasha; Altschul, Brett; Schindler, Matthias R.

2018-05-01

If any violation of Lorentz symmetry exists in the hadron sector, its ultimate origins must lie at the quark level. We continue the analysis of how the theories at these two levels are connected, using chiral perturbation theory. Considering a 2-flavor quark theory, with dimension-4 operators that break Lorentz symmetry, we derive a low-energy theory of pions and nucleons that is invariant under local chiral transformations and includes the coupling to external fields. The pure meson and baryon sectors, as well as the couplings between them and the couplings to external electromagnetic and weak gauge fields, contain forms of Lorentz violation which depend on linear combinations of quark-level coefficients. In particular, at leading order the electromagnetic couplings depend on the very same combinations as appear in the free particle propagators. This means that observations of electromagnetic processes involving hadrons—such as vacuum Cerenkov radiation, which may be allowed in Lorentz-violating theories—can only reliably constrain certain particular combinations of quark coefficients.

Surface deformation and fracture processes of materials under external force are important for understanding and developing materials. Here, a combined horizontal universal mechanical testing machine (HUMTM)-atomic force microscope (AFM) system is developed by modifying UMTM to combine with AFM and designing a height-adjustable stabilizing apparatus. Then the combined HUMTM-AFM system is evaluated. Finally, as initial demonstrations, it is applied to analyze the relationship among macroscopic mechanical properties, surface nanomorphological changes under external force, and fracture processes of two kinds of representative large scale thin film materials: polymer material with high strain rate (Parafilm) and metal material with low strain rate (aluminum foil). All the results demonstrate the combined HUMTM-AFM system overcomes several disadvantages of current AFM-combined tensile/compression devices including small load force, incapability for large scale specimens, disability for materials with high strain rate, and etc. Therefore, the combined HUMTM-AFM system is a promising tool for materials research in the future.

Gender Roles, Externalizing Behaviors, and Substance Use Among Mexican-American Adolescents

PubMed Central

KULIS, STEPHEN; MARSIGLIA, FLAVIO F.; NAGOSHI, JULIE L.

2010-01-01

A sample of 60 male and 91 female Mexican-American adolescents (age 13–18) were administered measures of positive (i.e., assertive masculinity, affective femininity) and negative (i.e., aggressive masculinity, submissive femininity) gender roles, internalizing and externalizing problem behaviors, peer substance use, and own substance use (alcohol, cigarettes, marijuana). Negative gender roles were significantly correlated with internalizing and externalizing problems for both boys and girls, with aggressive masculinity also predicting peer substance use for both genders. Assertive masculinity significantly predicted lower alcohol use in boys, and this effect was not mediated by internalizing problems, externalizing problems, or peer substance use. Negative gender roles significantly predicted higher alcohol use in girls, but this effect was almost completely mediated by internalizing problems, externalizing problems, and peer substance use. Results are discussed in terms of gender role socialization among Mexican Americans. PMID:21031145

Effects of reinforcement on children's academic behavior as a function of self-determined and externally imposed contingencies1

PubMed Central

Felixbrod, Jeffrey J.; O'Leary, K. Daniel

1973-01-01

This experiment was designed to compare the effects of contingent reinforcement under conditions of self-determined and externally imposed performance standards. A major purpose was to examine the maintenance of self-imposed performance standards over time. Children in one contingent reinforcement condition self-determined their academic performance standards. The same performance standards were externally imposed upon children in a second contingent reinforcement condition who were yoked to subjects in the first condition. Children in a no-reinforcement control condition performed in the absence of external reward. Behavioral productivity of the self-determination condition was greater than that of the no-reinforcement condition. Further, no attenuation of the efficacy of contingent reinforcement occurred when performance standards were self-determined rather than externally imposed. Over six sessions, children became progressively more lenient in their self-imposed performance demands in the absence of social surveillance. PMID:16795405

Promoting justice or perpetuating prejudice? Interrupting external motivation in multicultural training.

PubMed

Gushue, George V; Hinman, Kimberly A

2018-01-01

The effects of responding to social pressure (external motivation) are short-lived. Multicultural training, however, seeks to promote change in students and trainees that will be transformative and long-lasting. To this end, understanding the motivational factors that inform training is key. The present study was an investigation of the factors underlying external motivation to respond without prejudice for White individuals from the perspective of Higgins's regulatory focus (promotion and prevention) and regulatory mode (assessment and locomotion) theories. The results indicate that locomotion was negatively associated with external motivation to respond without prejudice, while assessment and prevention were positively associated with external motivation. Taken together, findings highlight the importance of cultivating locomotion (action oriented) motivation and inhibiting prevention (loss oriented) and assessment (preoccupation with finding the correct answer) motivations in multicultural training. Implications for training, effective action for justice, and future research are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

[Multi-Target Recognition of Internal and External Defects of Potato by Semi-Transmission Hyperspectral Imaging and Manifold Learning Algorithm].

The present paper put forward a non-destructive detection method which combines semi-transmission hyperspectral imaging technology with manifold learning dimension reduction algorithm and least squares support vector machine (LSSVM) to recognize internal and external defects in potatoes simultaneously. Three hundred fifteen potatoes were bought in farmers market as research object, and semi-transmission hyperspectral image acquisition system was constructed to acquire the hyperspectral images of normal external defects (bud and green rind) and internal defect (hollow heart) potatoes. In order to conform to the actual production, defect part is randomly put right, side and back to the acquisition probe when the hyperspectral images of external defects potatoes are acquired. The average spectrums (390-1,040 nm) were extracted from the region of interests for spectral preprocessing. Then three kinds of manifold learning algorithm were respectively utilized to reduce the dimension of spectrum data, including supervised locally linear embedding (SLLE), locally linear embedding (LLE) and isometric mapping (ISOMAP), the low-dimensional data gotten by manifold learning algorithms is used as model input, Error Correcting Output Code (ECOC) and LSSVM were combined to develop the multi-target classification model. By comparing and analyzing results of the three models, we concluded that SLLE is the optimal manifold learning dimension reduction algorithm, and the SLLE-LSSVM model is determined to get the best recognition rate for recognizing internal and external defects potatoes. For test set data, the single recognition rate of normal, bud, green rind and hollow heart potato reached 96.83%, 86.96%, 86.96% and 95% respectively, and he hybrid recognition rate was 93.02%. The results indicate that combining the semi-transmission hyperspectral imaging technology with SLLE-LSSVM is a feasible qualitative analytical method which can simultaneously recognize the internal and external defects potatoes and also provide technical reference for rapid on-line non-destructive detecting of the internal and external defects potatoes.

[Modeling of an influence of indicators of social stress on demographic processes in regions of the Russian Federation].

PubMed

Burkin, M M; Molchanova, E V

To assess an impact of indicators of social stress on demographic processes in regions of the Russian Federation using statistical methods. The data of Rosstat «Regions of Russia» and «Health care in Russia» were used as information base. Indicators of about 80 subjects of the Russian Federation (without autonomous areas) for the ten-year period (2005-2014) have been created in the form of the database consisting of the following blocks: medico-demographic situation, level of economic development of the territory and wellbeing of the population, development of social infrastructure, ecological and climatic conditions, scientific researches and innovations. In total, there were about 70 indicators. Panel data for 80 regions of Russia in 10 years, which combine both indicators of spatial type (cross-section data), and information on temporary ranks (time-series data), were used. Various models of regression according to the panel data have been realized: the integrated model of regression (pooled model), regression model with the fixed effects (fixed effect model), regression model with random effects (random effect model). Main demographic indicators (life expectancy, birth rate, mortality from the external reasons) are to a great extent connected with socio-economic factors. Social tension (social stress) caused by transition to market economy plays an important role. The integral assessment of the impact of the average per capita monetary income, incidence of alcoholism and alcoholic psychoses, criminality, sales volume of alcoholic beverages per capita and marriage relations on demographic indicators is presented. Results of modeling allow to define the priority directions in the field of development of mental health and psychotherapeutic services in the regions of the Russian Federation.

Conceptions of ability as stable and self-evaluative processes: a longitudinal examination.

PubMed

Pomerantz, E M; Saxon, J L

2001-01-01

It has generally been taken for granted that conceiving of ability as stable leads to negative self-evaluative processes, particularly in the face of failure. Yet, a close examination of the empirical findings suggests that the picture may be more complex. In this research, a three-wave longitudinal design spanning 12 months was employed. Older elementary school children (N = 932) indicated their conceptions of academic and social ability as stable to external forces and to internal forces. They also provided information about the importance they place on academic and social competence, their knowledge about academic and social performance, their preference for academic challenge, their perceptions of academic and social competence, and their attributions for academic and social performance. Children's grades in school and their acceptance by peers were obtained as indicators of performance. Over time, conceiving of ability as stable to external forces, particularly in the academic domain, appeared to heighten the importance placed on competence, performance knowledge, preference for challenge, perceptions of competence, and self-enhancing attributions. In contrast, conceptions of ability as stable to internal forces, particularly in the academic domain, appeared to be fostered by placing little importance on competence, a lack of performance knowledge, avoidance of challenge, negative perceptions of competence, self-deprecating attributions, and poor performance.

Social capital, collective action, and communal grazing lands in Uganda

PubMed Central

Call, Maia; Jagger, Pamela

2018-01-01

Recent scholars have found that collective action can be harnessed to sustainably manage common property, contrary to longstanding hypotheses that without effective external regulation community members will exploit communal resources. Researchers have also found that social capital, in addition to biophysical conditions and community attributes, is an important element of successful collective action. However, few studies exploring this topic have specifically examined communal grazing land, which is a critical component of rural livelihoods in many parts of the developing world. To address this gap, we explore the role that collective action plays in maintaining communal grazing lands through bridging, bonding, and linking social capital. In cases where the community does have communal grazing lands, we also explore the role of social capital in determining the condition of the land and the inclusiveness of access. Our analyses draw upon a community-level dataset composed of Uganda RePEAT survey data linked with high resolution gridded socio-environmental data. We observe that strong community bonds are associated with higher odds of successful collective action. However, increased links to external market forces may decrease the odds of successful collective action. These findings provide additional evidence for the complex relationship between social capital, collective action, and common property natural resource management. PMID:29377036

Monitoring tobacco brand websites to understand marketing strategies aimed at tobacco product users and potential users.

Limited information exists about strategies and methods used on brand marketing websites to transmit pro-tobacco messages to tobacco users and potential users. This study compared age verification methods, themes, interactive activities and links to social media across tobacco brand websites. This study examined 12 tobacco brand websites representing four tobacco product categories: cigarettes, cigar/cigarillos, smokeless tobacco, and e-cigarettes. Website content was analyzed by tobacco product category and data from all website visits (n = 699) were analyzed. Adult smokers (n=32) coded websites during a one-year period, indicating whether or not they observed any of 53 marketing themes, seven interactive activities, or five external links to social media sites. Most (58%) websites required online registration before entering, however e-cigarette websites used click-through age verification. Compared to cigarette sites, cigar/cigarillo sites were more likely to feature themes related to "party" lifestyle, and e-cigarette websites were much more likely to feature themes related to harm reduction. Cigarette sites featured greater levels of interactive content compared to other tobacco products. Compared to cigarette sites, cigar/cigarillo sites were more likely to feature activities related to events and music. Compared to cigarette sites, both cigar and e-cigarette sites were more likely to direct visitors to external social media sites. Marketing methods and strategies normalize tobacco use by providing website visitors with positive themes combined with interactive content, and is an area of future research. Moreover, all tobacco products under federal regulatory authority should be required to use more stringent age verification gates. Findings indicate the Food and Drug Administration (FDA) should require brand websites of all tobacco products under its regulatory authority use more stringent age verification gates by requiring all visitors be at least 18 years of age and register online prior to entry. This is important given that marketing strategies may encourage experimentation with tobacco or deter quit attempts among website visitors. Future research should examine the use of interactive activities and social media on a wide variety of tobacco brand websites as interactive content is associated with more active information processing. © The Author 2017.

Does the Presence of Anxiety and ADHD Symptoms Add to Social Impairment in Children with Autism Spectrum Disorder?

PubMed

Factor, Reina S; Ryan, Sarah M; Farley, Julee P; Ollendick, Thomas H; Scarpa, Angela

2017-04-01

Children with autism spectrum disorder (ASD) experience internalizing and externalizing problems at higher rates than typically developing children, which could worsen social impairment. The present study compared impairment scores (social responsiveness scale, 2nd edition; SRS-2 scores) in 57 children (3-17 years, 82.5% male) with ASD, either with or without heightened levels of anxiety or ADHD symptoms, all per parent report. Children with heightened anxiety problems showed higher scores on four SRS-2 subscales (Social Cognition, Social Communication, Social Motivation, and Restricted Interests and Repetitive Behavior). Children with heightened ADHD traits showed higher scores on two subscales (Social Communication and Social Awareness). These findings suggest similarities and differences in how social deficits in ASD may worsen with anxiety or ADHD symptoms.

Economic evaluation of interventions for problem drinking and alcohol dependence: do within-family external effects make a difference?

PubMed

Mortimer, Duncan; Segal, Leonie

2006-01-01

To propose methods for the inclusion of within-family external effects in clinical and economic evaluations. To demonstrate the extent of bias due to the exclusion of within-family external effects when measuring the relative performance of interventions for problem drinking and alcohol dependence. The timing and magnitude of treatment effects are modified to accommodate the external health-related quality of life impact of having a problem or dependent drinker in the family home. The inclusion of within-family external effects reduces cost per QALY estimates of interventions for problem drinking and alcohol dependence thereby improving the performance of all evaluated interventions. In addition, the inclusion of within-family external effects improves the relative performance of interventions targeted at those with moderate-to-severe alcohol dependence as compared to interventions targeted at less severe alcohol problems. Failure to take account of external effects in clinical and economic evaluations results in an uneven playing field. Interventions with readily quantifiable health benefits (where social costs and benefits are predominantly comprised of private costs and benefits) are at a distinct advantage when competing for public funding against interventions with quantitatively important external effects.

To determine what should be done as a preventive medicine physician by analysing the effect of polypharmacy and herbal treatment. This survey-based, cross-sectional study was carried out at Istanbul Okmeydani Training and Research Hospital, Istanbul, Turkey, from February to May 2015, and comprised patients using two or more medicines at full strength for at least 240 days. The patients were classified into two groups. Group A comprised those who were using less than 4 medications (at least 2), while group B comprised patients using more than 4 medications. The short version of World Health Organisation's quality-of-life questionnaire was applied. SPSS 22 was used for data analysis. Of the 350 participants, 106(30.3%) were receiving herbal treatment while 244(69.7%) had no such treatment. Group B patients had meaningfully lower scores for body, spiritual, social and external environment (p=0.001). Moreover, the patients having no herbal or supportive treatment scored significantly higher in the physical, spiritual, social relations and external environment (p=0.001). In group A, patients receiving no herbal treatment scored meaningfully higher in all fields, including physical (p=0.009), social relations (p=0.043) and external environment (p=0.001). Old age, living alone, level of education, having a regular monthly income, the number of drugs used, chronic diseases and herbal treatments affected the life quality.

Generation of powerful microwave pulses by channel power summation of two X-band phase-locked relativistic backward wave oscillators

NASA Astrophysics Data System (ADS)

Xiao, Renzhen; Deng, Yuqun; Chen, Changhua; Shi, Yanchao; Sun, Jun

2018-03-01

We demonstrate both theoretically and experimentally the possibility of the generation of powerful microwave pulses by channel power summation of two X-band phase-locked relativistic backward wave oscillators (RBWOs). A modulated electron beam induced by an external signal can lead the microwave field with an arbitrary initial phase to the same equilibrium phase, which is determined by the initial phase of the external signal. A high-current dual-beam accelerator was built to drive the two RBWOs. An external signal was divided into two channels with an adjusted relative phase and injected into the two RBWOs through two TE10-TEM mode converters. The generated microwaves were combined with a power combiner consisting of two TM01-TE11 serpentine mode converters with a common output. In the experiments, as the input power for each channel was 150 kW, the two RBWOs output 3.1 GW and 3.7 GW, respectively, the jitter of the relative phase of two output microwaves was about 20°, and the summation power from the power combiner is 6.2 GW, corresponding to a combination efficiency of 91%.

Instruments to measure social support and related constructs in pregnant adolescents: a review.

PubMed

Perrin, K M; McDermott, R J

1997-01-01

This review examines some of the key issues related to measuring social support and identifies 28 instruments which have been used in research with pregnant adolescents. The major external and internal variables that affect social support for pregnant adolescents are defined. Relevant questions are offered to guide the researcher in the choice of a social support instrument, and the 28 social support instruments are described by author, availability, length and item type, psychometric properties, and selected references and notes. Although not an exhaustive list, these 28 instruments are representative of the broad spectrum of measurement tools available which were chosen because they have been used in a variety of social support research endeavors.

Extrapolating Survival from Randomized Trials Using External Data: A Review of Methods

2016-01-01

This article describes methods used to estimate parameters governing long-term survival, or times to other events, for health economic models. Specifically, the focus is on methods that combine shorter-term individual-level survival data from randomized trials with longer-term external data, thus using the longer-term data to aid extrapolation of the short-term data. This requires assumptions about how trends in survival for each treatment arm will continue after the follow-up period of the trial. Furthermore, using external data requires assumptions about how survival differs between the populations represented by the trial and external data. Study reports from a national health technology assessment program in the United Kingdom were searched, and the findings were combined with “pearl-growing” searches of the academic literature. We categorized the methods that have been used according to the assumptions they made about how the hazards of death vary between the external and internal data and through time, and we discuss the appropriateness of the assumptions in different circumstances. Modeling choices, parameter estimation, and characterization of uncertainty are discussed, and some suggestions for future research priorities in this area are given. PMID:27005519

Coping with birthparent loss in adopted children.

PubMed

Smith, Daniel W; Brodzinsky, David M

2002-02-01

Relationships among adopted children's appraisals of birthparent loss, their coping strategies for managing such loss, and child and parent reports of child adjustment were investigated within the context of a stress and coping model of adoption adjustment. Eighty-two 8-12-year-old adopted children and one of their parents participated. Children completed questionnaires assessing their negative affect about birthparent loss, their curiosity about birthparents, their use of coping strategies to manage birthparent-related distress, and their levels of depression, anxiety, and global self-worth. Parents reported on children's externalizing and internalizing behavior problems and social competence. Children who reported higher levels of negative affect about birthparent loss also reported higher levels of depression and lower self-worth. Curiosity about birthparents predicted parent-rated externalizing behavior. Behavioral avoidant coping was associated with greater self-reported anxiety and parent-rated externalizing behavior, whereas problem solving coping was associated with increased parent-rated social competence. The findings, though limited by issues of measurement and sampling, add to the knowledge base regarding adopted children's appraisal and coping behaviors, and provide partial support for a stress and coping model of adopted children's adjustment.

Meeting stroke survivors' perceived needs: a qualitative study of a community-based exercise and education scheme.

PubMed

Reed, Mary; Harrington, Rachel; Duggan, Aine; Wood, Victorine A

2010-01-01

A qualitative study using a phenomenological approach, to explore stroke survivors' needs and their perceptions of whether a community stroke scheme met these needs. Semi-structured in-depth interviews of 12 stroke survivors, purposively selected from participants attending a new community stroke scheme. Interpretative phenomenological analysis of interviews by two researchers independently. Participants attending the community stroke scheme sought to reconstruct their lives in the aftermath of their stroke. To enable this they needed internal resources of confidence and sense of purpose to 'create their social self', and external resources of 'responsive services' and an 'informal support network', to provide direction and encouragement. Participants felt the community stroke scheme met some of these needs through exercise, goal setting and peer group interaction, which included social support and knowledge acquisition. Stroke survivors need a variety of internal and external resources so that they can rebuild their lives positively post stroke. A stroke-specific community scheme, based on exercise, life-centred goal setting, peer support and knowledge acquisition, is an external resource that can help with meeting some of the stroke survivor's needs.

Effects of Mass Media and Cultural Drift in a Model for Social Influence

NASA Astrophysics Data System (ADS)

Mazzitello, Karina I.; Candia, Julián; Dossetti, Víctor

In the context of an extension of Axelrod's model for social influence, we study the interplay and competition between the cultural drift, represented as random perturbations, and mass media, introduced by means of an external homogeneous field. Unlike previous studies [J. C. González-Avella et al., Phys. Rev. E 72, 065102(R) (2005)], the mass media coupling proposed here is capable of affecting the cultural traits of any individual in the society, including those who do not share any features with the external message. A noise-driven transition is found: for large noise rates, both the ordered (culturally polarized) phase and the disordered (culturally fragmented) phase are observed, while, for lower noise rates, the ordered phase prevails. In the former case, the external field is found to induce cultural ordering, a behavior opposite to that reported in previous studies using a different prescription for the mass media interaction. We compare the predictions of this model to statistical data measuring the impact of a mass media vasectomy promotion campaign in Brazil.

Sustaining Community Participation: What Remains After the Money Ends?

SUSTAINING COMMUNITY PARTICIPATION: WHAT REMAINS AFTER THE MONEY ENDS? - A major concern confronting development specialists in the education sector is the sustainability of project activities and outcomes, that is, their ability to persist once external funding ends. The increased attention of international development-assistance organizations to sustainability reflects the greater recent focus on outcome-based funding. The present study investigates differences between six communities in Ghana that varied in their ability to sustain externally initiated community-participation activities beyond the life of the external development-assistance project that promoted those activities. It was hypothesized that high- and low-sustaining communities differ in eight managerial and socio-cultural dimensions suggested by earlier research to be important for sustainability of community-level activities: planning, transparency, leadership, and participation, on one hand, and, on the other, social cohesion, resources, community skills, and valuing of education. Findings indicate that leadership and social cohesion are the two most vital elements in the sustainability of organizational structures intended to promote community participation in the oversight of local schools. Other factors suggested by the model are largely subsumed under leadership, so that the model can be simplified.

Social conditions are the first environment that modulate external factors which impact on health. In turn gender is a decisive factor in these social determinants of health. This paper analyzes gender bias in the health system as a relevant part in social determinants. We can distinguish three types of bias: cognitive, social, and institutional. In the institutional biases, we analyze the risks of gender and costs originated from the coordination between the health system and the system of social protection. Finally, we suggest a series of measures to minimize these biases and risks. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Host Plant Use by Competing Acacia-Ants: Mutualists Monopolize While Parasites Share Hosts

PubMed Central

Kautz, Stefanie; Ballhorn, Daniel J.; Kroiss, Johannes; Pauls, Steffen U.; Moreau, Corrie S.; Eilmus, Sascha; Strohm, Erhard; Heil, Martin

2012-01-01

Protective ant-plant mutualisms that are exploited by non-defending parasitic ants represent prominent model systems for ecology and evolutionary biology. The mutualist Pseudomyrmex ferrugineus is an obligate plant-ant and fully depends on acacias for nesting space and food. The parasite Pseudomyrmex gracilis facultatively nests on acacias and uses host-derived food rewards but also external food sources. Integrative analyses of genetic microsatellite data, cuticular hydrocarbons and behavioral assays showed that an individual acacia might be inhabited by the workers of several P. gracilis queens, whereas one P. ferrugineus colony monopolizes one or more host trees. Despite these differences in social organization, neither of the species exhibited aggressive behavior among conspecific workers sharing a tree regardless of their relatedness. This lack of aggression corresponds to the high similarity of cuticular hydrocarbon profiles among ants living on the same tree. Host sharing by unrelated colonies, or the presence of several queens in a single colony are discussed as strategies by which parasite colonies could achieve the observed social organization. We argue that in ecological terms, the non-aggressive behavior of non-sibling P. gracilis workers — regardless of the route to achieve this social structure — enables this species to efficiently occupy and exploit a host plant. By contrast, single large and long-lived colonies of the mutualist P. ferrugineus monopolize individual host plants and defend them aggressively against invaders from other trees. Our findings highlight the necessity for using several methods in combination to fully understand how differing life history strategies affect social organization in ants. PMID:22662191

Psychological theory in an interdisciplinary context: psychological, demographic, health-related, social, and environmental correlates of physical activity in a representative cohort of community-dwelling older adults.

Physical activity (PA) in older adults is influenced by a range of environmental, demographic, health-related, social, and psychological variables. Social cognitive psychological models assume that all influences on behaviour operate indirectly through the models constructs, i.e., via intention and self-efficacy. We evaluated direct, indirect, and moderating relationships of a broad range of external variables with physical activity levels alongside intention and self-efficacy. We performed a cross-sectional survey of a representative and stratified (65-80 and 80+ years; deprived and affluent) sample of 584 community-dwelling people, resident in Scotland. Objectively measured physical activity and questionnaire data were collected. Self-efficacy showed unique relationships with physical activity, controlling for demographic, mental health, social, environmental, and weather variables separately, but the relationship was not significant when controlling for physical health. Overall, results indicating support for a mediation hypothesis, intention and self-efficacy statistically mediate the relationship of most domain variables with physical activity. Moderation analyses show that the relationship between social cognitions and physical activity was stronger for individuals with better physical health and lower levels of socio-economic deprivation. Social cognitive variables reflect a range of known environmental, demographic, health-related and social correlates of physical activity, they mediate the relationships of those correlates with physical activity and account for additional variance in physical activity when external correlates are controlled for, except for the physical health domain. The finding that the social cognition-physical activity relationship is higher for participants with better health and higher levels of affluence raises issues for the applicability of social cognitive models to the most disadvantaged older people.

Explaining Differential Reporting of Victimization between Parents and Children: A Consideration of Social Biases.

PubMed

John, Sufna Gheyara; DiLalla, Lisabeth F

2013-09-01

Studies have shown that children and parents provide different reports of children's victimization, with children often reporting more victimization. However, the reason for this differential reporting is unclear. This study explored two types of social biases (emotion recognition and perceived impairment) in parents and children as possible reasons underlying differential reporting. Six- to 10-year-old children and one of their parents were tested in a lab. Testing included subjective measures of parent alexithymic traits, child perceived impairment from victimization, and child- and parent-reported frequency of children's peer victimization and internalizing and externalizing difficulties. Parents and children also completed an objective measure of emotion recognition. Both types of social bias significantly predicted reports of children's peer victimization frequency as well as internalizing and externalizing difficulties, as rated by parents and children. Moreover, child perceived impairment bias, rather than parent emotion bias, best predicted differential reporting of peer victimization. Finally, a significant interaction demonstrated that the influence of child perceived impairment bias on differential reporting was most salient in the presence of parent emotion bias. This underscores the importance of expanding interventions for victimized youth to include the restructuring of social biases.

Understanding health constraints among rural-to-urban migrants in China.

PubMed

Li, Yan

2013-11-01

The main purpose of this article is to examine the understanding and experience of health and health care among rural-to-urban migrants in China, and to explain the impact of the internal factors of migrants themselves and the external factors of their social environment. Understanding the perceptions and consciousness of health issues among migrants is crucial to prevention, intervention, and other health-related measures for the migrant population in China, but this has rarely been explored in studies. On the basis of a case study of a migrant community in Beijing, I explore the migrants' understandings of health and health care and analyze factors in the social environment, including exclusion from the social system and the possibility of health participation, exclusion from social relation networks, obstructed channels of health maintenance, and exclusion of crowd psychology, which impact heavily on their health understanding and health behavior. I argue that the internal and the external factors are linked together closely and interact as reciprocal causation. However, the migrants should not be seen as primarily responsible, because their poor understanding of health mainly results from the socioeconomic environment in which they live and work.

Experiences of homophobia among gay and bisexual men: results from a cross-sectional study in seven countries.

Chard, Anna N; Finneran, Catherine; Sullivan, Patrick S; Stephenson, Rob

2015-01-01

Experiences of homophobic discrimination are associated with an increased prevalence of psychological disorders and increased odds of reporting suicidal ideation among gay and bisexual men. We examine two domains of homophobia--external homophobic discrimination and internalised homophobia--and their associations with sexual orientation, demographic characteristics, relationships and social support among a sample of gay and bisexual men from seven countries. Sexually active gay and bisexual men aged over 18 and residing in Australia, Brazil, Canada, South Africa, Thailand, the UK and the USA were recruited through banner advertisements on Facebook. Two outcomes were examined: reporting experiences of homophobic discrimination and reporting feelings of internalised homophobia. No covariates were consistently significantly associated with experiencing external homophobic discrimination across countries. Across all countries, bisexually identifying respondents reported significantly greater feelings of internalised homophobia. Respondents in Brazil and the UK reporting a main partner, and respondents in Australia, Brazil, Canada, South Africa, Thailand and the USA reporting a larger gay/bisexual social network, reported significantly fewer feelings of internalised homophobia. Results suggest an ameliorative effect of social networks on experiencing homophobia. Additional research should focus on the mechanisms through which social networks reduce feelings of internalised homophobia.

Social skills and behavior problems of urban, African American preschoolers: role of parenting practices, family conflict, and maternal depression.

2006-10-01

This study examined the role of parenting, family routines, family conflict, and maternal depression in predicting the social skills and behavior problems of low-income African American preschoolers. A sample of 184 African American mothers of Head Start children completed participant and child measures in a structured interview. Results of regression analyses revealed that mothers who utilized more positive parenting practices and engaged in more family routines had children who displayed higher levels of total prosocial skills. Positive parenting and lower levels of maternal depressive symptoms were predictive of fewer externalizing and internalizing child behavior problems. Lower family conflict was linked with fewer externalizing problems. Implications of the study for future research and intervention are discussed. (c) 2007 APA, all rights reserved

Mobile Context Provider for Social Networking

NASA Astrophysics Data System (ADS)

Santos, André C.; Cardoso, João M. P.; Ferreira, Diogo R.; Diniz, Pedro C.

The ability to infer user context based on a mobile device together with a set of external sensors opens up the way to new context-aware services and applications. In this paper, we describe a mobile context provider that makes use of sensors available in a smartphone as well as sensors externally connected via bluetooth. We describe the system architecture from sensor data acquisition to feature extraction, context inference and the publication of context information to well-known social networking services such as Twitter and Hi5. In the current prototype, context inference is based on decision trees, but the middleware allows the integration of other inference engines. Experimental results suggest that the proposed solution is a promising approach to provide user context to both local and network-level services.

The external field perpendicular to the silicene monolayer affects in increasing of the current. Under 0.2 eV external field, the current reaches the maximum peak at Vb = 0.3 eV with the increase is about 60% from what it is in zero external field.

Motivation for aggressive religious radicalization: goal regulation theory and a personality × threat × affordance hypothesis

PubMed Central

McGregor, Ian; Hayes, Joseph; Prentice, Mike

2015-01-01

A new set of hypotheses is presented regarding the cause of aggressive religious radicalization (ARR). It is grounded in classic and contemporary theory of human motivation and goal regulation, together with recent empirical advances in personality, social, and neurophysiological psychology. We specify personality traits, threats, and group affordances that combine to divert normal motivational processes toward ARR. Conducive personality traits are oppositional, anxiety-prone, and identity-weak (i.e., morally bewildered). Conducive threats are those that arise from seemingly insurmountable external forces and frustrate effective goal regulation. Conducive affordances include opportunity for immediate and concrete engagement in active groups that are powered by conspiracy narratives, infused with cosmic significance, encouraging of moral violence, and sealed with religious unfalsifiability. We propose that ARR is rewarding because it can spur approach motivated states that mask vulnerability for people whose dispositions and circumstances would otherwise leave them mired in anxious distress.

2016-12-01

The relationship between sleep disorders and Internet addiction has been little work. Given the importance of these disorders, we felt it appropriate to make a synthesis of available data and to establish causality or accountability between Internet addiction and the onset of sleep disorders. A literature review was then performed. We selected scientific articles in English and French, published between 1987 and 2016 by consulting the databases Medline, Embase, PsycINFO and Google Scholar. The words used alone or in combination are as follows: addiction, dependence, Internet, behavioral addiction, sleep. A computer screen light inhibits melatonin secretion and acts as a real external desynchronizer circadian rhythm resulting in a withdrawal syndrome or syndrome sleep phase delay when the stress of social awakening is suppressed. We assume here that the specific treatment of addictive disorders have an influence on sleep disorders. Copyright © 2016. Published by Elsevier Masson SAS.

Sperm competition risk drives rapid ejaculate adjustments mediated by seminal fluid

PubMed Central

Steeves, Tammy E; Gemmell, Neil J; Rosengrave, Patrice C

2017-01-01

In many species, males can make rapid adjustments to ejaculate performance in response to sperm competition risk; however, the mechanisms behind these changes are not understood. Here, we manipulate male social status in an externally fertilising fish, chinook salmon (Oncorhynchus tshawytscha), and find that in less than 48 hr, males can upregulate sperm velocity when faced with an increased risk of sperm competition. Using a series of in vitro sperm manipulation and competition experiments, we show that rapid changes in sperm velocity are mediated by seminal fluid and the effect of seminal fluid on sperm velocity directly impacts paternity share and therefore reproductive success. These combined findings, completely consistent with sperm competition theory, provide unequivocal evidence that sperm competition risk drives plastic adjustment of ejaculate quality, that seminal fluid harbours the mechanism for the rapid adjustment of sperm velocity and that fitness benefits accrue to males from such adjustment.

The Prospective Association Between Internalizing Symptoms and Adolescent Alcohol Involvement and the Moderating Role of Age and Externalizing Symptoms.

Colder, Craig R; Shyhalla, Kathleen; Frndak, Seth; Read, Jennifer P; Lengua, Liliana J; Hawk, Larry W; Wieczorek, William F

2017-12-01

As predicted by self-medication theories that drinking is motivated by a desire to ameliorate emotional distress, some studies find internalizing symptoms (e.g., anxiety, depression) increase risk of adolescent drinking; however, such a risk effect has not been supported consistently. Our prior work examined externalizing symptoms as a potential moderator of the association between internalizing symptoms and adolescent alcohol use to explain some of the inconsistencies in the literature. We found that internalizing symptoms were protective against early adolescent alcohol use particularly for youth elevated on externalizing symptoms (a 2-way interaction). Our sample has now been followed for several additional assessments that extend into young adulthood, and the current study tests whether the protective effect of internalizing symptoms may change as youth age into young adulthood, and whether this age-moderating effect varied across different clusters of internalizing symptoms (social anxiety, generalized anxiety, and depression). Internalizing symptoms were hypothesized to shift from a protective factor to a risk factor with age, particularly for youth elevated on externalizing symptoms. A community sample of 387 adolescents was followed for 9 annual assessments (mean age = 12.1 years at the first assessment and 55% female). Multilevel cross-lagged 2-part zero-inflated Poisson models were used to test hypotheses. The most robust moderating effects were for levels of alcohol use, such that the protective effect of all internalizing symptom clusters was most evident in the context of moderate to high levels of externalizing problems. A risk effect of internalizing symptoms was evident at low levels of externalizing symptoms. With age, the risk and protective effects of internalizing symptoms were evident at less extreme levels of externalizing behavior. With respect to alcohol-related problems, findings did not support age moderation for generalized anxiety or depression, but it was supported for social anxiety. Findings highlight the importance of considering the role of emotional distress from a developmental perspective and in the context of externalizing behavior problems.

In external-beam radiotherapy, using external markers is one of the most reliable tools to predict tumor position, in clinical applications. The main challenge in this approach is tumor motion tracking with highest accuracy that depends heavily on external markers location, and this issue is the objective of this study. Four commercially available feature selection algorithms entitled 1) Correlation-based Feature Selection, 2) Classifier, 3) Principal Components, and 4) Relief were proposed to find optimum location of external markers in combination with two "Genetic" and "Ranker" searching procedures. The performance of these algorithms has been evaluated using four-dimensional extended cardiac-torso anthropomorphic phantom. Six tumors in lung, three tumors in liver, and 49 points on the thorax surface were taken into account to simulate internal and external motions, respectively. The root mean square error of an adaptive neuro-fuzzy inference system (ANFIS) as prediction model was considered as metric for quantitatively evaluating the performance of proposed feature selection algorithms. To do this, the thorax surface region was divided into nine smaller segments and predefined tumors motion was predicted by ANFIS using external motion data of given markers at each small segment, separately. Our comparative results showed that all feature selection algorithms can reasonably select specific external markers from those segments where the root mean square error of the ANFIS model is minimum. Moreover, the performance accuracy of proposed feature selection algorithms was compared, separately. For this, each tumor motion was predicted using motion data of those external markers selected by each feature selection algorithm. Duncan statistical test, followed by F-test, on final results reflected that all proposed feature selection algorithms have the same performance accuracy for lung tumors. But for liver tumors, a correlation-based feature selection algorithm, in combination with a genetic search algorithm, proved to yield best performance accuracy for selecting optimum markers.

Multiple environmental risk factors in early childhood predict a broad range of adverse developmental outcomes. However, most prior longitudinal research has not illuminated explanatory mechanisms. Our main goals were to examine predictive associations between cumulative ecological risk factors in early childhood and children's later externalizing problems and to determine whether these associations were explained by variations in parenting quality. Participants were 241 children (118 girls) at risk for school-age conduct problems and their parents and teachers. Children were approximately 3 years old at Time 1 (T1) and 10 years old at Time 2 (T2). Reports of contextual risk at T1 were used to develop a cumulative risk index consisting of 6 singular risk variables from 3 ecological levels: social resources (low income; social isolation), family resources (marital aggression; poor total family functioning), and maternal resources (single parent status; poor maternal mental health). At T1, parenting variables were measured (corporal punishment, warm responsiveness, maternal efficacy, and negative perceptions of child behavior). At T2, mothers, fathers, and teachers reported child externalizing problems. Johnson's relative weight analysis revealed that the cumulative risk index was a more powerful predictor of age 10 years externalizing behavior than any of the singular contextual risk variables. Adverse parenting mediated the effects of cumulative risk on later child externalizing problems. Our findings have significant implications for understanding long-term effects of multiple contextual risk factors present in early childhood and for the implementation of positive parenting interventions early on.

To develop the combined method of treatment of hemorrhoids with arterial ligation under Doppler control and laser destruction of internal and external hemorrhoids. The study included 100 patients with chronic hemorrhoids stage II and III. Combined method of HAL-laser was used in study group, HAL RAR-technique in control group 1 and closed hemorrhoidectomy with linear stapler in control group 2. Сomparative evaluation of results in both groups was performed. Combined method overcomes the drawbacks of traditional surgical treatment and limitations in external components elimination which are inherent for HAL-RAR. Moreover, it has a higher efficiency in treating of hemorrhoids stage II-III compared with HAL-RAR and is equally safe and well tolerable for patients. This method does not increase the risk of recurrence, reduces incidence of complications and time of disability.

The management of pilon fractures is controversial primarily due to the high rate of complications irrespective of the mode of treatment. Limited internal fixation with external fixation is associated with minimal soft tissue handling. This may reduce the chances of wound dehiscence and infection. This study was designed to evaluate the functional and clinical outcomes in patients treated with limited internal fixation combined with external fixation in pilon fractures. This study was conducted as a prospective clinical study on 56 skeletally mature patients with closed fractures with poor skin condition, and with open grade 1 and grade 2 distal tibial intra-articular fractures. All patients were treated with combined limited internal fixation and ankle spanning external fixation. All fractures in this series united with an average time period of union of 18.3weeks (ranging from 13 weeks to 30 weeks). There was no non-union in any case. There was malunion in 4 cases, varus malunion (>5 degree) in 2 cases and recurvatum in another 2 cases). Excellent to good functional results were observed in 88% cases based on the modified Ovadia and Beals score. The mean ankle dorsiflexion and planter flexion movements were 10.2±5.3 degrees and 27.4±7.2 degrees respectively. infections occurred in 6 patients which included 4 pin tract infections and 2 superficial wound infection, all 6 healed after removal of pin tract and with oral antibiotics. The technique of combined external fixation with internal fixation is safe and effective management option for intra-articular distal tibial fractures.

The emergence of large communities is inherently associated with the creation of social structures. Connections between individuals are indispensable for cooperative action of agents building social groups. Moreover, social groups usually evolve and their structure changes over time. Consequently, an underlying network connecting individuals is not static, reflecting an ongoing adaptation to new conditions. The evolution of social connections is influenced by the relative position (hierarchy) of individuals building the system as well as by the availability of resources. We explore this aspect of human ambition by modeling the interplay of social networking and an uneven distribution of external resources. The model naturally generates social hierarchies. Remarkably, this social structure exhibits a rise-and-fall behavior. A well pronounced quasi-periodic dynamics, which is closely associated with the dissipation of resources that are needed to sustain the social links, is revealed.

Patterns of engagement in cyber bullying and four types of traditional bullying were examined using latent class analysis (LCA). Demographic differences and externalizing problems were evaluated across latent class membership. Data were obtained from the 2005-2006 Health Behavior in School-aged Survey and the analytic sample included 7,508 U.S. adolescents in grades 6 through 10. LCA models were tested on physical bullying, verbal bullying, social exclusion, spreading rumors, and cyber bullying behaviors. Three latent classes were identified for each gender: All-Types Bullies (10.5% for boys and 4.0% for girls), Verbal/Social Bullies (29.3% for boys and 29.4% for girls), and a Non-Involved class (60.2% for boys and 66.6% for girls). Boys were more likely to be All-Types Bullies than girls. The prevalence rates of All-Types and Verbal/Social Bullies peaked during grades 6 to 8 and grades 7 and 8, respectively. Pairwise comparisons across the three latent classes on externalizing problems were conducted. Overall, the All-Types Bullies were at highest risk of using substances and carrying weapons, the Non-Involved were at lowest risk, and the Verbal/Social Bullies were in the middle. Results also suggest that most cyber bullies belong to a group of highly aggressive adolescents who conduct all types of bullying. This finding does not only improve our understanding of the relation between cyber bullying and traditional bullying, but it also suggests that prevention and intervention efforts could target cyber bullies as a high-risk group for elevated externalizing problems.

Investigations Into Internal and External Aspects of Dynamic Agent-Environment Couplings

NASA Astrophysics Data System (ADS)

Dautenhahn, Kerstin

This paper originates from my work on `social agents'. An issue which I consider important to this kind of research is the dynamic coupling of an agent with its social and non-social environment. I hypothesize `internal dynamics' inside an agent as a basic step towards understanding. The paper therefore focuses on the internal and external dynamics which couple an agent to its environment. The issue of embodiment in animals and artifacts and its relation to `social dynamics' is discussed first. I argue that embodiment is linked to a concept of a body and is not necessarily given when running a control program on robot hardware. I stress the individual characteristics of an embodied cognitive system, as well as its social embeddedness. I outline the framework of a physical-psychological state space which changes dynamically in a self-modifying way as a holistic approach towards embodied human and artificial cognition. This framework is meant to discuss internal and external dynamics of an embodied, natural or artificial agent. In order to stress the importance of a dynamic memory I introduce the concept of an `autobiographical agent'. The second part of the paper gives an example of the implementation of a physical agent, a robot, which is dynamically coupled to its environment by balancing on a seesaw. For the control of the robot a behavior-oriented approach using the dynamical systems metaphor is used. The problem is studied through building a complete and co-adapted robot-environment system. A seesaw which varies its orientation with one or two degrees of freedom is used as the artificial `habitat'. The problem of stabilizing the body axis by active motion on a seesaw is solved by using two inclination sensors and a parallel, behavior-oriented control architecture. Some experiments are described which demonstrate the exploitation of the dynamics of the robot-environment system.

The sense of controlling one's own actions is fundamental to normal human mental function, and also underlies concepts of social responsibility for action. However, it remains unclear how the wider social context of human action influences sense of agency. Using a simple experimental design, we investigated, for the first time, how observing the action of another person or a robot could potentially influence one's own sense of agency. We assessed how observing another's action might change the perceived temporal relationship between one's own voluntary actions and their outcomes, which has been proposed as an implicit measure of sense of agency. Working in pairs, participants chose between two action alternatives, one rewarded more frequently than the other, while watching a rotating clock hand. They judged, in separate blocks, either the time of their own action, or the time of a tone that followed the action. These were compared to baseline judgements of actions alone, or tones alone, to calculate the perceptual shift of action toward outcome and vice versa. Our design focused on how these two dependent variables, which jointly provide an implicit measure of sense of agency, might be influenced by observing another's action. In the observational group, each participant could see the other's actions. Multivariate analysis showed that the perceived time of action and tone shifted progressively toward the actual time of outcome with repeated experience of this social situation. No such progressive change occurred in other groups for whom a barrier hid participants' actions from each other. However, a similar effect was observed in the group that viewed movements of a human-like robotic hand, rather than actions of another person. This finding suggests that observing the actions of others increases the salience of the external outcomes of action and this effect is not unique to observing human agents. Social contexts in which we see others controlling external events may play an important role in mentally representing the impact of our own actions on the external world.

Demographic and Indication-Specific Characteristics Have Limited Association With Social Network Engagement: Evidence From 24,954 Members of Four Health Care Support Groups

PubMed Central

2017-01-01

Background Digital health social networks (DHSNs) are widespread, and the consensus is that they contribute to wellness by offering social support and knowledge sharing. The success of a DHSN is based on the number of participants and their consistent creation of externalities through the generation of new content. To promote network growth, it would be helpful to identify characteristics of superusers or actors who create value by generating positive network externalities. Objective The aim of the study was to investigate the feasibility of developing predictive models that identify potential superusers in real time. This study examined associations between posting behavior, 4 demographic variables, and 20 indication-specific variables. Methods Data were extracted from the custom structured query language (SQL) databases of 4 digital health behavior change interventions with DHSNs. Of these, 2 were designed to assist in the treatment of addictions (problem drinking and smoking cessation), and 2 for mental health (depressive disorder, panic disorder). To analyze posting behavior, 10 models were developed, and negative binomial regressions were conducted to examine associations between number of posts, and demographic and indication-specific variables. Results The DHSNs varied in number of days active (3658-5210), number of registrants (5049-52,396), number of actors (1085-8452), and number of posts (16,231-521,997). In the sample, all 10 models had low R2 values (.013-.086) with limited statistically significant demographic and indication-specific variables. Conclusions Very few variables were associated with social network engagement. Although some variables were statistically significant, they did not appear to be practically significant. Based on the large number of study participants, variation in DHSN theme, and extensive time-period, we did not find strong evidence that demographic characteristics or indication severity sufficiently explain the variability in number of posts per actor. Researchers should investigate alternative models that identify superusers or other individuals who create social network externalities. PMID:28213340

Adherence in severe asthma is a difficult health problem. Although psychosocial factors may be responsible for non-adherence, few longitudinal studies have investigated their link with adherence, with most studies having focused on pharmacology. Sixty patients with severe asthma were recruited. Adherence was electronically monitored using peak flow measurements at entry and after 1 year of follow-up. Eysenck's Personality Inventory, Rotter's Locus of Control (LOC), and health control beliefs were all studied. Multiple logistic regression (MLR) was used for risk calculations. Initially, subjects with poor adherence had an external LOC (P=.001) and a high extraversion score (P=.003) compared to those with good adherence. The lie score was high in all patients. Nocturnal awakenings were highly significantly correlated with poor adherence (P=.006). After 1 year, patient adherence, extraversion, and neuroticism remained unchanged. The LOC changed in subjects with poor adherence, showing a less "external" orientation (P=.007). The health parameters were better at the end of the study. By MLR analysis, externality, extraversion, and low social desirability were associated with poor adherence. Patients with poor adherence had a greater probability of nocturnal symptoms. No specific personality type was associated with lack of adherence in the present study, but a high extraversion score, a low social desirability score, and a high level of externality were all predictors of poor adherence.

Welfare standards in hospital mergers.

There is a broad literature on the consequences of applying different welfare standards in merger control. Total welfare is usually defined as the sum of consumer and provider surplus, i.e., potential external effects are not considered. The general result is then that consumer welfare is a more restrictive standard than total welfare, which is advantageous in certain situations. This relationship between the two standards is not necessarily true when the merger has significant external effects. We model mergers on hospital markets and allow for not-profit-maximizing behavior of providers and mandatory health insurance. Mandatory health insurance detaches the financial and consumption side of health care markets, and the concept consumer in merger control becomes non-evident. Patients not visiting the merging hospitals still are affected by price changes through their insurance premiums. External financial effects emerge on not directly affected consumers. We show that applying a restricted interpretation of consumer (neglecting externality) in health care merger control can reverse the relation between the two standards; consumer welfare standard can be weaker than total welfare. Consequently, applying the wrong standard can lead to both clearing socially undesirable and to blocking socially desirable mergers. The possible negative consequences of applying a simple consumer welfare standard in merger control can be even stronger when hospitals maximize quality and put less weight on financial considerations. We also investigate the implications of these results for the practice of merger control.

Effects of combined anterior and posterior plication of the glenohumeral ligament complex for the repair of anterior glenohumeral instability: a biomechanical study.

Arthroscopic repair techniques for anterior instability most commonly address only the anterior band of the inferior glenohumeral ligament. This study quantitatively evaluated and compared the combined anterior and posterior arthroscopic plication by repairing both the anterior and posterior bands of the inferior glenohumeral ligament with the anterior arthroscopic plication alone. Six cadaveric shoulders were tested in 60° of glenohumeral abduction with 22 N of compressive force in the coronal plane for intact, after anterior capsular stretching, after anterior repair, and after posterior arthroscopic repair. Range of motion, glenohumeral translation, and glenohumeral kinematics throughout the rotational range of motion were measured with a MicroScribe 3DLX (Immersion, San Jose, CA, USA). Glenohumeral contact pressure and area were measured with a pressure measurement system (Tekscan Inc, South Boston, MA, USA). Stretching the anterior capsule significantly increased external rotation and anterior translation (P < .05). After anterior plication, external rotation was restored to the intact condition, and anterior translation was significantly decreased compared with stretched condition (P < .05). The combined anterior and posterior plication significantly decreased internal rotation compared with the intact condition. The anterior plication shifted the humeral head posterior in external rotation, whereas the combined anterior and posterior plication shifted the humeral head anterior in internal rotation (P < .05). Both repairs led to a decrease in glenohumeral contact area at 45° external rotation (P < .07). The addition of a posterior plication to anterior plication for anterior instability has no biomechanical advantage over a typical arthroscopic anterior repair for anterior glenohumeral instability.

2010-03-01

Every mass or mass group, from atoms and molecules to stars and galaxies,has no motion, is vibrating, rotating,or moving linearly, singularly or in some combination. When created, the excess energy of creation will generate a vibration, rotation and/or linear motion besides the mass or mass group. Curvilinear or orbital motion is linear motion in an external force field. External forces, such as photon, molecular or stellar collisions may over time modify the inital rotational, vibratory or linear motions of the mass of mass group. The energy equation for each mass or mass group is E=mc^2 + 1/2mv^2 + 1/2I2̂+ 1/2kx0^2 + WG+ WE+ WM.

Although combined changes in eating habits and physical activity are pivotal to hypercholesterolemia management and the prevention of cardiovascular disease, little is known about the factors influencing the adoption of both behaviors by adults with hypercholesterolemia. The goal of this study was to identify psychological factors that predict a combined adoption of dietary modification and physical activity among adults with hypercholesterolemia. We recruited a sample of 1100 adults with hypercholesterolemia (56.9% male, mean age=56.5 years) through a nationally representative online panel. Participants reported their physical activity using the International Physical Activity Questionnaire (IPAQ) and their eating habits using a Food-Frequency Questionnaire (FFQ). We assessed a comprehensive set of psychological variables, including hypercholesterolemia knowledge and perception, patient's cardiovascular history, doctor-patient relationship, social-cognitive beliefs, and personality traits. Based on IPAQ and FFQ scores, we classified participants into four groups (dietary modification plus physical exercise, dietary modification, physical exercise, passive). Our analysis showed that subjective hypercholesterolemia knowledge, beliefs about the effects of hypercholesterolemia, external locus of control (other people and chance), nutrition and physical exercise self-efficacy, and trait self-control significantly influenced the simultaneous adoption of physical exercise and dietary modification. This study highlights the importance of psychological factors in predicting the combined adoption of physical exercise and dietary modification among adults with hypercholesterolemia. Addressing these factors could help improve hypercholesterolemia prevention strategies. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Internet based social media websites represent a growing space for interpersonal interaction. Research has been conducted in relation to the potential role of social media in the support of individuals with physical health conditions. However, limited research exists exploring such utilisation by individuals with experience of mental health problems. It could be proposed that access to wider support networks and knowledge could be beneficial for all users, although this positive interpretation has been challenged. The present study focusses on a specific discussion as a case study to assess the role of the website www.twitter.com as a medium for interpersonal communication by individuals with experience of mental disorder and possible source of feedback to mental health service providers. An electronic search was performed to identify material contributing to an online conversation entitled #dearmentalhealthprofessionals. Output from the search strategy was combined in such a way that repeated material was eliminated and all individual material anonymised. The remaining textual material was reviewed and combined in a thematic analysis to identify common themes of discussion. 515 unique communications were identified relating to the specified conversation. The majority of the material related to four overarching thematic headings: The impact of diagnosis on personal identity and as a facilitator for accessing care; Balance of power between professional and service user; Therapeutic relationship and developing professional communication; and Support provision through medication, crisis planning, service provision and the wider society. Remaining material was identified as being direct expression of thanks, self-referential in its content relating to the on-going conversation or providing a link to external resources and further discussion. The present study demonstrates the utility of online social media as both a discursive space in which individuals with experience of mental disorder may share information and develop understanding, and a medium of feedback to mental health service providers. Further research is required to establish potential individual benefit from the utilisation of such networks, its suitability as a means of service provision feedback and the potential role for, and user acceptability of, mental health service providers operating within the space.

To discuss the clinical effects of external fixator combined with limited internal fixation in the treatment of pediatric distal femur fractures. From January 2008 to June 2014, 17 children of distal femur fractures were treated by external fixator combined with limited internal fixation. There were 12 males and 5 females, aged from 6 to 13 years old with an average of 10.2 years, ranged in the course of disease from 1 h to 2 d. Preoperative diagnoses were confirmed by X-ray films in all children. There were 11 patients with supracondylar fracture , and 6 patients with intercondylar comminuted fracture. According to AO/ASIF classification, 9 fractures were type A1, 5 cases were type A2,and 3 cases were type C1. The intraoperative and postoperative complications, postoperative radiological examination, lower limbs length and motion of knee joints were observed. Knee joint function was assessed by KSS score. All the patients were followed up from 6 to 38 months with an average of 24.4 months. No nerve or blood vessel injury was found. One case complicated with the external fixation loosening, 2 cases with the infection of pin hole and 3 cases with the leg length discrepancy. Knee joint mobility and length measurement (compared with the contralateral), the average limited inflexion was 10 degrees (0 degrees to 20 degrees), the average limited straight was 4 degrees (0 degrees to 10), the average varus or valgus angle was 3 degrees (0 degrees to 5 degrees). KSS of the injured side was (96.4 +/- 5.0) points at final follow-up, 16 cases got excellent results and 1 good. All fractures obtained healing and no epiphyseal closed early was found. External fixator combined with limited internal fixation has advantages of simple operation, reliable fixation, early functional exercise in treating pediatric distal femurs fractures.

Purpose: To observe, by retrospective analysis, the curative effects and complications due to californium-252 ({sup 252}Cf) neutron intracavitary brachytherapy (ICBT) combined with external-beam radiotherapy (EBRT) in the treatment of cervical cancer. Methods and Materials: From February 1999 to December 2007, 696 patients with cervical cancer (Stages IB to IIIB) were treated with {sup 252}Cf-ICBT in combination of EBRT. Of all, 31 patients were at Stage IB, 104 at IIA, 363 at IIB, 64 at IIIA, and 134 at IIIB. Californium-252 ICBT was delivered at 7-12 Gy per insertion per week, with a total dose of 29-45 Gy to reference pointmore » A in three to five insertions. The whole pelvic cavity was treated with 8-MV X-ray external irradiation at 2 Gy per fraction, four times per week. After 16-38 Gy of external irradiation, the center of the whole pelvic field was blocked with a 4-cm-wide lead shield, with a total external irradiation dose of 44-56 Gy. The total treatment course was 5 to 6 weeks. Results: Overall survival rate at 3 and 5 years for all patients was 76.0% and 64.9%, respectively. Disease-free 3- and 5-year survival rates of patients were 71.2% and 58.4%, respectively. Late complications included vaginal contracture and adhesion, radiation proctitis, radiation cystitis, and inflammatory bowel, which accounted for 5.8%, 7.1%, 6.2%, and 4.9%, respectively. Univariate analysis results showed significant correlation of stage, age, histopathologic grade, and lymph node status with overall survival. Cox multiple regression analysis showed that the independent variables were stage, histopathologic grade, tumor size, and lymphatic metastasis in all patients. Conclusion: Results of this series suggest that the combined use of {sup 252}Cf-ICBT with EBRT is an effective method for treatment of cervical cancer.« less

Schizophrenia and affective psychoses are both associated with impaired social functioning, but the extent to which childhood behavioral impairments are present prior to onset of illness is less well studied. Moreover, the concurrent relationship of childhood behavior problems and premorbid IQ with subsequent psychotic disorder has not been established. We investigated whether childhood behavior problems are associated with increased risk for adult schizophrenia or affective psychosis, independently and in combination with IQ. The study included individuals with schizophrenia (N=47), affective psychoses (N=45) and non-psychotic controls (N=1496) from the New England Family Study. Behavior problems were prospectively assessed from standardized clinician observations at ages 4 and 7. IQ was assessed with the Stanford-Binet at age 4 and the Wechsler Intelligence Scale for Children at age 7. We found externalizing problems at age 4 and externalizing and internalizing problems at age 7 were associated with later schizophrenia, and both internalizing and externalizing problems at ages 4 and 7 were associated with later development of affective psychoses. Lower IQ at ages 4 and 7 was associated with schizophrenia, while lower IQ was associated with affective psychoses at age 7 only. Examined simultaneously, both lower IQ and behavior problems remained associated with risk of schizophrenia, while only behavior problems remained associated with affective psychoses. Behavior problems appear to be a general marker of risk of adult psychotic disorder, while lower childhood IQ is more specific to risk of schizophrenia. Future research should clarify the premorbid evolution of behavior and cognitive problems into adult psychosis. Copyright © 2016 Elsevier B.V. All rights reserved.

The aim of this study was to compare inequalities in mortality (all causes and by cause) by occupational group and educational level between men and women living in France in the 1990s. Data were analysed from a permanent demographic sample currently including about one million people. The French Institute of Statistics (INSEE) follows the subjects and collects demographic, social and occupational information from the census schedules and vital status forms. Causes of death were obtained from the national file of the French Institute of Health and Medical Research (INSERM). A relative index of inequality (RII) was calculated to quantify inequalities as a function of educational level and occupational group. Overall all-cause mortality, mortality due to cancer, mortality due to cardiovascular disease and mortality due to external causes (accident, suicide, violence) were considered. Overall, social inequalities were found to be wider among men than among women, for all-cause mortality, cancer mortality and external-cause mortality. However, this trend was not observed for cardiovascular mortality, for which the social inequalities were greater for women than for men, particularly for mortality due to ischaemic cardiac diseases. This study provides evidence for persistent social inequalities in mortality in France, in both men and women. These findings highlight the need for greater attention to social determinants of health. The reduction of cardiovascular disease mortality in low educational level groups should be treated as a major public health priority.
