Juvenile hormone titers, juvenile hormone biosynthesis, ovarian development and social environment in Bombus terrestris.

The effects of the social environment and age on juvenile hormone (JH) and reproduction were investigated by measuring ovarian development, hemolymph levels of JH III, and rates of JH biosynthesis from the same individual bumble bees (Bombus terrestris). Differences in social environment were associated with differences in rates of JH biosynthesis, JH titer and ovarian development. Young queenless workers had a higher rate of JH biosynthesis, JH titer and ovarian development than queenright (QR) workers of similar age. Dominant workers in QR colonies had a higher rate of JH biosynthesis, JH titer and ovarian development than low ranked workers of similar size. There was a positive correlation between JH titer and ovarian development, but no correlation between rate of JH biosynthesis and ovarian development or between JH biosynthesis and JH titer. Both JH titer and rate of JH biosynthesis increased with age from emergence to 3 days of age, but 6-day-old workers, egg-laying workers, and actively reproducing queens had high JH titers and highly developed ovaries but low rates of JH biosynthesis. These results show that reproduction in B. terrestris is strongly affected by the social environment and the influence of the environment on reproduction is mediated by JH. Our data also indicate that the rate of JH biosynthesis measured in vitro is not a reliable indicator of JH titer or ovarian development in B. terrestris; possible reasons are discussed.

Religion as a resource for positive youth development: religion, social capital, and moral outcomes.

Although existing literature demonstrates that developmental benefits are associated with religion for adolescents, little is understood about the dynamics of this relationship. Drawing on social capital theory, this study tested a conceptual model exploring socially embedded religious influences on moral outcomes. A three-dimensional model of social capital demonstrated how social interaction, trust, and shared vision enable social ties associated with religiousness to influence moral behavior. Structural equation modeling was used with data gathered from 735 urban youths to test a proposed model of the effects of religiousness on moral outcomes. Results suggested that religiously active youths report higher levels of social capital resources and that the influence of adolescent religiousness on moral outcomes was mediated through social capital resources. Suggestions for further research and implications for faith-based youth development organizations are considered.

Population structure in the Arab world and its impact on integration and development trends.

The author examines three issues: "population structure in the Arab world; trends making for integration and unity among the Arab countries; and economic and social development trends." Data from the United Nations for 1985 and from recent censuses are used to discuss population size, growth, and spatial distribution; the labor force; age and sex distribution; and fertility, mortality, and natural increase. Figures are presented separately for 22 Arab countries. Attention is then given to the relationships between population structure and economic and social development and between development and Arab unity and integration.

Intelligence and behaviour in children born after in-vitro fertilization treatment.

This study is the first to examine a large group of children born after in-vitro fertilization (IVF) who were old enough at the time of the investigation to make it possible to draw conclusions about the outcome. The aim of the study was to assess the cognitive, behavioural and social development of the children. The study comprised 99 IVF children, 33-85 months of age, from the University Hospitals of Lund and Malmö, Sweden. The children's development was assessed with the Griffiths' scales of mental development. The children's behaviour was delineated through semi-structured interviews with their mothers, covering 50 different behaviours. The mothers also filled in Achenbach's Child Behaviour Checklist (CBCL). All children were examined by a paediatric neurologist. The results were compared to Swedish population groups. Of the children born, 66% were singletons, 22% were twins, 12% were triplets and 28% were born prematurely in gestational weeks 32-36. The cognitive development of the IVF children was excellent, and their behaviour was normal when compared with two Swedish population groups. Our conclusion was that the development, behaviour and social adaptation of the children was very satisfactory.

Gender differences in schizophrenia.

Sex differences in schizophrenia can be caused by the disease process itself, by genetic and hormonal differences, by differences in the maturation and morphology of the brain and in age- and gender-specific behavioural patterns. These hypotheses will be tested on the major results reported in the literature as well as on different levels (epidemiology, risk factors, animal experiments, a controlled clinical study) on data from the ABC Schizophrenia Study. Symptomatology, lifetime risk and symptom-related course of illness-the latter without consideration of age-show no gender differences. However, until menopause illness onset is delayed and severity of illness is reduced by oestrogen on the level of gene expression and transmitter functioning. Oestrogen has an antagonistic effect on the-familial or exogenous-predisposition to illness. As a result, the age distribution of onset and the severity of first-episode illness in young men and post-menopausal women differ from the normal. First intervention trials with oestrogen substitution of neuroleptic therapy have demonstrated antipsychotic effects. The poorer social course of schizophrenia in men than in premenopausal women is accounted for by men's lower level of social development at illness onset and the subsequent impediment of their further development. Men's socially adverse illness behaviour, too, is a contributing factor. Scarcity of the knowledge of differences in the development, morphology and functioning of the male and female brain does not yet allow any definitive conclusions about gender differences in schizophrenia.

HIV and development.

BACKGROUND: Epidemics of disease are milestones in the history of humanity, nodes in the web of causes and consequences which shape the development of societies. HIV has been with us for long enough to reveal global patterns of distribution which can be linked to currently accepted indicators of social development. Its highest prevalence is found in poor societies, societies in turmoil, among the displaced, the powerless, and the marginalized. The prevalence of HIV is an indicator of uneven or dysfunctional social development. DISCUSSION: How HIV will affect the development of nations is difficult to predict. A major impact on national macro-economic indicators such as gross national product is unlikely. The most important social and economic effect of the epidemic in developing countries will be an increasing gap between rich and poor, and the feminization of poverty.

Developmental effects of early immune stress on aggressive, socially reactive, and inhibited behaviors.

The origins of individual differences in social development are examined in relation to early stress (immune challenge) and social milieu (maternal behavior) in a genetic-developmental analysis using an animal model. Neonatal male mice (5 or 6 days of age) from two lines of mice selectively bred for high versus low levels of inter-male aggressive behavior received a standard immune challenge (i.p. injections of 0.05 mg/kg endotoxin or saline). Animals were reared by their line-specific biological dam or by a foster dam from a line bred without selection. Adult levels of social behaviors were assessed in a dyadic test (age 45-50 days). Mice from the high-aggressive line show more developmental sensitivity to immune challenge than mice from the low-aggressive line, and line differences persist regardless of the early maternal environment. As adults, endotoxin-treated mice from the high-aggressive line have lower levels of aggressive behavior, longer latency to attack, and higher rates of socially reactive and inhibited behaviors compared to saline controls. Developmental effects of endotoxin in the low-aggressive line are minimal: endotoxin increases socially reactive behaviors, compared to saline controls, but only for mice reared by their biological dams. Rearing by foster dams increases social exploration in the low-aggressive line. The findings raise novel questions regarding the openness of behavioral systems to effects of nonobvious but omnipresent features of the environment, such as antigenic load, how these effects are integrated to affect social development and psychopathology, and the nature of intrinsic factors that contribute to individual differences in sensitivity to early stressors.

Community-based survey versus sentinel site sampling in determining the nutritional status of rural children. Implications for nutritional surveillance and the development of nutritional programmes.

A study of the anthropometric status of under-5-year-olds was conducted in the Nqutu district of KwaZulu by means of a representative community-based sample and concurrent samples from primary health care clinics, preschools and primary schools. The first objective of this exercise was to determine the extent of acute nutritional stress in the district as an indication of the appropriateness of food relief efforts in the region. The absence of wasting and the high prevalence of stunting (37.5%) in the community-based sample suggested that the main problem is chronic socio-economic underdevelopment, rather than a severe or immediate lack of food. The fact that fewer than 20% of households are in any way reliant on domestic production for their maize requirements explains why the recent drought has not had a greater impact on the nutritional status of this vulnerable group. This study confirms that the more recent emphasis of the National Nutrition and Social Development Programme on social development is appropriate. An equally important objective of this study was to evaluate the usefulness of clinics, preschools and schools as sites for the collection of anthropometric data and the development of nutritional programmes. This preliminary attempt to develop the methodology for district-based nutrition surveillance suggested that all these sites have limitations both in respect of data collection and community access. The implications of using these sites and the developments needed to improve their usefulness in a future nutrition surveillance system are discussed.

The role of optimism in social network development, coping, and psychological adjustment during a life transition.

The authors investigated the extent to which social support and coping account for the association between greater optimism and better adjustment to stressful life events. College students of both genders completed measures of perceived stress, depression, friendship network size, and perceived social support at the beginning and end of their 1st semester of college. Coping was assessed at the end of the 1st semester. Greater optimism, assessed at the beginning of the 1st semester of college, was prospectively associated with smaller increases in stress and depression and greater increases in perceived social support (but not in friendship network size) over the course of the 1st semester of college. Mediational analyses were consistent with a model in which increases in social support and greater use of positive reinterpretation and growth contributed to the superior adjustment that optimists experienced.

[Influences on neuromotor development of 5 to 10-year-old children in Basel].

In a longitudinal study concerning somatic, psychic, and social development of children in Basle, the neuromotor development at the age of 5 and 10 years was examined. Motor retardation shows significant correlations with psychic and social development. The way 5 year old children of working mothers have been taken care of showed a significant influence on motor development. A retardation in motor development of kindergarten children indicates an increased probability for further retardations in school age, too.

[Future needs in health protection and preventive health].

Health protection is a social political program and dosely connected with the social development. It is pointed out that progress in health protection demands progress in social development. One of the main problems of preparing health protection strategies is to assess the numberless risks for health. Because of the fact that risk assessment is full of social implications people have to be involved in assessing risks. Stressing this fact it is concluded that concepts of health protection mainly reflect ideas about people and social life more than ideas about health and illness. Promoting health protection in the GDR four key problems of major concern are summarized: 1) improving information and education, 2) netting the responsibility of the whole society, 3) further progress in socialist democracy and communal life, 4) increasing the role of health protection in the whole social-political activities.

Developing a social contract between the medical school and the community.

Medical schools are under considerable pressure to reform their conventional curricula. Problem-based and community-oriented instruction are the predominant choices of change. The focus on the community as a teaching resource has occurred partly in order to make medical education relevant to community health needs, and partly in an attempt to replace the declining teaching opportunities available in specialized tertiary care hospitals. This paper offers a theoretical perspective on community-oriented initiatives by examining how one such initiative has been developed in an attempt to establish a social contract between a medical school and a community. An evaluation of the experience is described as a means to assess the success of the social contract at an early stage of its development.

The stress-disequilibrium theory: chronic disease development, low social control, and physiological de-regulation.

The Stress-Disequilibrium Theory is based on a new generalized analytic three-level model based on thermodynamics to describe the process of physiological risk development. This approach explains how low social control could cause chronic disease through chronic de-regulation of our highly integrated physiological systems. Could low external social control lead to low internal physiological control: i.e. compromised self-regulation--and then disease? The theory implicitly explores the evidence for the physiological causes of chronic diseases, including cardiovascular diseases, at a high level (i.e. a non-reductionist level) and in a unifying manner--to provide a potentially easier linkage to the broad social policy consequences implied by the global economy. Evidence from our own recent Heart Rate Variability monitoring and job strain research (5) is presented which assesses the effect of low control on autonomic regulation on the heart. The theory is consistent with the Demand/Control Model, and could be considered its underlying theoretical explanation.

Social dramatics: social skills development for the chronically mentally ill.

The purpose of this study was to investigate the use of social dramatics as a clinical tool for teaching social skills to the chronically mentally ill on adult inpatient units of a state hospital. The research tested the hypothesis that patients exposed to social dramatics with videotape feedback would demonstrate greater ability to perform social skills as measured by the Nurses' Observation Scale for Inpatient Evaluation (NOSIE-30). Fifteen schizophrenic adults of both sexes meeting specific criteria were randomly assigned to experimental and control groups. Subjects were exposed over an 8-week period to randomly introduced social dramatic scenarios. The Wilcoxin test for two independent samples was used for testing differences between experimental and control groups. The research findings supported the hypothesis for one positive factor, social competence. The findings did not support any treatment effect on either social interest and personal neatness or irritability, manifest psychosis, and psychotic depression. There were no significant differences on the total score NOSIE-30. Recommendations for psychiatric nursing are made. Limitations of research methodologies and sample size were addressed.

Causes of changes in brain noradrenaline systems and later effects on responses to social stressors in rhesus monkeys: the cascade hypothesis.

Disruption of social attachments in social primates produces a protest-despair response. In rhesus monkeys, the response is probably adaptive in the feral environment, although the despair stage resembles human depression in many respects. The severity of the response varies between individuals and is affected by deprivation of certain classes of social stimuli during development. Social deprivation is associated with differences in the concentrations of noradrenaline (NA) in cerebrospinal fluid and in responses to agents that affect catecholamine systems. Thus, early rearing conditions and pre-existing genetic or perinatal differences between monkeys can have long-term effects on the response to social separation, and NA system release and/or receptor mechanisms are involved. NA systems appear to mediate adaptation to the environment from the level of perception to reorganization of neural tissue. Adaptation to the social environment may involve a cascade of changes that begins with behavioural coping attempts and terminates in structural reorganization of regions of the cerebral cortex. Processes at each level occur within environmentally appropriate but neurobiologically constrained time-frames. The cerebral NA system may be an adaptive mechanism that can fail or be damaged. Behavioural changes caused by such damage or failure would be manifested by inappropriate responses to environmental contingencies and inability to change behaviour to adapt to the prevailing environment. These features of NA system disorder could be common to depression and several other forms of human psychopathology.
