[Sterility--a woman's concern? Coping behavior and partnership structure of sterile couples of various diagnostic groups].

Three groups of sterile couples with functional, tubal and andrologically caused sterility were compared for the evaluation of sex- and diagnosis-dependent kinds of overcoming of their disease. Anamnestic data, anxiety, the coping strategy of sterility and as well the couple and personality structure are analysed. Independent of the organic cause of sterility the women showed a higher emotional reaction level (anxiety, coping stress) than their husbands. In all groups the "healthy" partners dominate. The subfertile men seem to be more subordinate, less engaged and interested and not so anxious as their wives and as the husbands of tubal sterile women. The healthy women with andrologically caused sterility present a highly emotional engagement in the overcoming and treatment of their disease. Possible emotional mechanisms and social stereotypes of self-presentation are discussed, which may cause the intense engagement of the women independent of the organic cause of sterility.

The reliability and validity of empirically scaled measures of psychological/verbal control and physical/sexual abuse: relationship between current negative mood and a history of abuse independent of other negative life events.

A history of psychological, physical, and sexual abuse, and circumscribed negative life events are precursors of current psychosomatic symptomatology. However, it is not known whether a history of abuse predicts current symptomatology, independent of other negative life events. We developed three new abuse scales: Psychological/Verbal; Control; and Physical/Sexual, which emerged when survey evidence of a random sample of the general public (N = 195) was factor analyzed. Test-retest reliabilities conducted on university students (N = 62) were moderate to high: Psychological/Verbal (r = 0.86); Control (r = 0.76); Physical/Sexual (r = 0.74); and Negative Life Events (r = 0.84). A Negative Life Event scale was developed to measure the cumulative effects of events (over the lifespan). A total score was calculated by summing event scores, weighted in proportion to 11 independent judges' ratings of distress for later use (Kendall's W; chi 2 = 183.67, df = 67, p < 0.0001). Thirteen criterion measures of current symptomatology were administered to a subsample of the original sample (N = 92), and collapsed into one factor for use as the criterion in a regression analysis; results showed that, independent of negative life events and respondent demographics, the Psychological/Verbal and Control Abuse Scales predicted current negative mood and psychosomatic complaints, and the association between current symptomatology and the Physical/Sexual Abuse Scale approached, but did not achieve, statistical significance (t = 1.99, df = 71, p < .0501). The present study demonstrates that the three abuse scales may be powerful predictors of current symptomatology, and that they have the potential for further investigating a wider range of current medical, physiological, and psychological problems.

Parasitism and behavioral dominance among male mice.

Infestations by the nematode Heligmosomoides polygyrus can prevent adult male mice from becoming behaviorally dominant. The effect is dose-dependent and is more likely to influence the development of dominance than to disrupt existing dominance relationships. Doses capable of exerting this effect are not lethal and do not affect weight.

Leadership in diversity.

As principal change agents, healthcare leaders are well positioned to integrate diversity into their institutions' organizational structure. Thus healthcare leaders must be competent in handling diversity issues. Diversity refers to any characteristic that helps shape a person's attitudes, behaviors, perspective, and interpretation of what is "normal." In the healthcare ministry, diversity encompasses the cultural differences that can be found across functions or among organizations when they merge or partner. Managers and supervisors will have to be familiar with the nuances of diversity if they are to be effective. Those managers who are not adept at incorporating diversity into human resource management may incorrectly evaluate subordinates' capabilities and provide inappropriate training or supervision. As a result, some employees may be underutilized. Others may resist needed direction, overlook instructions, or hide problems such as a language barrier. If executives, marketers, and strategic planners are to develop relevant healthcare services that take into account the needs of their constituencies, they will need to determine how different groups understand and access healthcare. Healthcare leaders who know how to uncover cultural dynamics and challenge cultural assumptions will go far in enabling their staff and managers to confront personal attitudes about community residents. Ultimately, quality of service delivery will be improved.

Are perceptions of fairness relationship-specific? The case of noblesse oblige.

Research in experimental economics suggests that decision making in strategic interactions is often guided by a concern for fairness. However, experimental economics studies routinely place participants of equal social status and no prior social history in anonymous interactions, a context that would tend to foster the adoption of an egalitarian fairness norm. Extensive research in anthropology (Fiske, 1991) and psychology (Bugental, 2000) suggests that social norms, including fairness norms, are relationship-specific, raising doubts about whether the concern for egalitarian fairness observed in the experimental economics literature would generalize to a wider range of social relations. In this paper we focus on an alternative social norm characteristic of hierarchical relationships: noblesse oblige--the obligation of high-ranking individuals to act honorably and beneficently towards subordinates. In a series of five experiments, we show that the norm of noblesse oblige predicts tolerance of free riding better than individual self-interest does.

Defence and safety: their function in social behaviour and psychopathology.

This paper suggests that our intuitive use and understanding of the concepts defence and safety can be opened up to more systematic study and theory. This may provide a powerful framework for biopsychosocial approaches in clinical psychology. Defence and safety can be seen as two fundamental, evolutionary adaptive, information-organizing systems. The operation of these two systems has major effects on biological patterns, social behaviour, relationships and the maturation of self-constructs. It is suggested that many forms of psychopathology represent the activation of evolved, defensive strategies. This paper explores the organization and operation of these two systems and attempts to integrate data from neuropsychological work with ideas from evolutionary theory and social psychology on the effects of threat sensitivity and defensiveness, and safety. It is suggested that interpersonal threats are the most common sources of human defensive behaviour and these are often about separation-rejection or power and subordination. In the latter part of the paper discussion will be on the way people try to create safe environments by putting others down, or by submitting to more powerful others.

From diffusion to anomalous diffusion: a century after Einstein's Brownian motion.

Einstein's explanation of Brownian motion provided one of the cornerstones which underlie the modern approaches to stochastic processes. His approach is based on a random walk picture and is valid for Markovian processes lacking long-term memory. The coarse-grained behavior of such processes is described by the diffusion equation. However, many natural processes do not possess the Markovian property and exhibit anomalous diffusion. We consider here the case of subdiffusive processes, which correspond to continuous-time random walks in which the waiting time for a step is given by a probability distribution with a diverging mean value. Such a process can be considered as a process subordinated to normal diffusion under operational time which depends on this pathological waiting-time distribution. We derive two different but equivalent forms of kinetic equations, which reduce to known fractional diffusion or Fokker-Planck equations for waiting-time distributions following a power law. For waiting time distributions which are not pure power laws one or the other form of the kinetic equation is advantageous, depending on whether the process slows down or accelerates in the course of time.

Ethics, a neglected dimension of power relationships of physician leaders.

OBJECTIVE: Physician leaders in obstetrics and gynecology find themselves in complex power relationships with administrative subordinates, administrative peers, and administrative superiors. The ethical dimensions of these power relationships have not been examined previously. STUDY DESIGN: The authors draw on the work of 3 major historic figures (John Gregory, Thomas Hobbes, and Friedrich Hoffmann) to identify for the first time 3 major types of power relationships and organizational cultures. Gregorian power relationships and organizational cultures are characterized by shared fiduciary responsibility that advances the core mission of a health care organization. Hobbesian power relationships and organizational cultures are characterized by relentless self-interest in a zero-sum game. Hoffmannian power relationships and organizational cultures are characterized by enlightened self-interest in a win-win game. RESULTS: The authors analyze the ethical dimensions of power relationships of physician leaders with subordinates, peers, and superiors and of organizational cultures. CONCLUSION: The authors support transformational leadership toward Gregorian power relationships and organizational cultures, using, when necessary, Hoffmannian power relationships and organizational cultures as a way station.

Gonadal hormones modulate the display of submissive behavior in socially defeated female Syrian hamsters.

There are striking differences in the behavioral response to social defeat between male and female Syrian hamsters. Whereas males exhibit a prolonged behavioral response to defeat (i.e., conditioned defeat), many females remain aggressive or show only a transient submissive response following defeat. The current study tested the hypothesis that sex steroids underlie this differential behavioral responsivity to social defeat. Female hamsters were ovariectomized and implanted with Silastic capsules containing estradiol (E(2)), testosterone (T), progesterone (P), dihydrotestosterone (DHT), or a blank capsule (no hormone replacement). After a 3-week recovery period, each subject was placed inside the home cage of a larger, more aggressive female for four 5-min defeat trials. The following day, each animal was tested for conditioned defeat by testing it in its own home cage in the presence of a smaller, non-aggressive intruder. Submissive, aggressive, social, and nonsocial behaviors were subsequently scored. Hamsters receiving E(2) or T displayed significantly lower levels of submissive behavior than did animals receiving P, DHT, or no hormone replacement. There were no significant differences in aggressive behavior among groups. These data suggest that gonadal hormones can influence submissive behavior in female hamsters. Collectively, these results suggest that the sex differences observed in conditioned defeat may, in part, be explained by sex differences in circulating gonadal hormones.

Semiochemicals and social signaling in the wild European rabbit in Australia: I. Scent profiles of chin gland secretion from the field.

The European rabbit (Oryctolagus cuniculus) uses the secretion of the chin gland in the maintenance of social status. Previous work has concentrated on secretion collected directly from the animal. In this study, the analysis was conducted by collecting scent marks made by free-ranging animals. Scent marks were found to be concentrated at the center of the area controlled by a social group, and at the boundaries between two adjacent social groups. Only the mark from dominant animals could be identified. Marks were also collected from the skin of rabbits, where they had been placed by the dominant individual. The mark found on the head of a subordinate animal may, in the future, be used to identify the dominant animal of the social group, who placed the mark.

A multilevel analysis of the interpersonal behavior of socially anxious people.

We investigate the interpersonal behavior of socially anxious (SA) and non-socially anxious (NSA) individuals at three different levels of analysis, focusing on the dimensions of warmth and dominance. Study 1 examines self-reported general interaction styles, Study 2 explores behavior occurring within the context of a single interaction, and in Study 3 we focus on the performance of a single conversational act (a disagreement). Studies 1 and 2 adopt the framework of Interpersonal Circumplex Theory (IPC; Kiesler, 1983), which is well suited for studying trait-level and interaction-level social behaviors, while Study 3 is grounded in Politeness Theory (PT; Brown & Levinson, 1987), which can be used to analyze individual acts at the microstructural level. The potential mutual relevance of PT and IPC is also discussed.

Urinary endocrine monitoring of the ovarian cycle and pregnancy in Goeldi's monkey (Callimico goeldii).

A non-invasive study of urinary hormones in 6 captive female Goeldi's monkeys provided accurate information on reproductive function. Conjugated oestrone accounted for 80-85% of the urinary oestrone and oestradiol measured. Radioimmunoassay measurements of conjugated oestrone provided a reliable indicator of cyclic ovarian function (mean cycle length: 24.1 +/- 0.9 days; n = 9) and pregnancy (gestation: 145, 155 days; n = 2). Measurements of urinary progesterone and pregnanediol glucuronide were only reliable as indicators of ovarian cyclicity. Elevations in urinary conjugated oestrone coincided with luteal-phase elevations of urinary progesterone and pregnanediol glucuronide. Urinary LH concentrations provided no indication of pituitary activity. However, the frequencies of female sexual solicitations of males were maximal when oestrone conjugate concentrations rose, suggesting a peri-ovulatory period. Ovulation was suppressed in 1 of 3 subordinate females housed in male-female-female trios.

[Effect of the activation of GABA A, benzodiazepine, and D2 dopamine receptors on the passive avoidance extinction in submissive and aggressive mice].

The effect of activation of GABAA, benzodiazepine, and D2 dopamine receptors on extinction of passive avoidance and their dependence on the initial state of aggressive and submissive C57BL/6J mice were studied. It was found that in mice with the submissive stereotype of behavior produced by experience of defeats in daily agonistic confrontations, extinction of the conditioned reaction occurred faster than in control mice. The activation of D2 receptors by quinpirole and of benzodiazepine receptors by medasepam before training restored the retrieval of the memory trace. A prolongation of extinction was observed in aggressive mice in comparison with control and submissive animals, and activation of GABAA by muscimol and benzodiazepine receptors by medazepam led to acceleration of extinction. Activation of D2 receptors was ineffective. Thus, the difference in initial behavioral strategy determined both the development of extinction of the passive avoidance and variability of participation of D2, GABAA, and benzodiazepine receptors in the maintenance of availability of the memory trace to retrieval.

Experimental evidence that kin discrimination in the Seychelles warbler is based on association and not on genetic relatedness.

In cooperative breeding systems driven by kin selection, effective kin-recognition cues are important. Recognition could be achieved by the direct assessment of the genetic relatedness of individuals or by learning through association. In the Seychelles warbler, Acrocephalus sechellensis, female subordinates maximize indirect fitness by preferentially helping genetically related nestlings. Help seems to be based on the continued presence of the primary female who previously fed the subordinate in the nest but it has, so far, been impossible to discount the direct assessment of genetic relatedness. We used a cross-fostering experiment to separate the two possible cues. Adult birds did not discriminate between their own and cross-fostered eggs or nestlings. Cross-fostering resulted in nestlings that were unrelated to the primary female that raised them, but control nestlings were closely related to their primary females. The proportions of cross-fostered and control female offspring that stayed and became helpers on their 'natal' territory were similar. However, for both groups the chance of becoming a subordinate helper was associated with the continued presence of the primary female and not with any other factor tested. Our study provides strong evidence that helping decisions are based on associative-learning cues.

Significance of kin relations and individual preferences in the social behaviour of Cebus apella.

Captive tufted capuchins (Cebus apella) formed a group characterized by greater affiliative behaviour within matrilines. Affiliation within the matriline is dependent upon social intimacy during infancy with matriline members. Courtship and mating are not identically distributed: subordinate and subadult males participate in a larger proportion of matings than of courtships. In all these aspects of social behaviour, variability across individuals contributes to the complex dynamics of the social group.

Single- and multilocus DNA fingerprinting of communally breeding pukeko: do copulations or dominance ensure reproductive success?

In behavioral and ecological studies the "function" of dominance hierarchies is thought to be related to reproductive success. In particular, dominant males are regarded as likely to gain a reproductive advantage due to enhanced "access" to females. We compare the dominance status of adults with the frequency of copulations and the patterns of parentage in communally breeding pukeko or purple swamphen (Porphyrio porphyrio melanotus). This avian species has an unusual social system, often breeding in polygynandrous groups in which there is a strong dominance hierarchy. Typically, during the breeding season, there is considerable sexual activity, with heterosexual and homosexual copulations between adults being commonplace. Hae III-digested DNA from individuals belonging to breeding groups was hybridized to the minisatellite DNA probe YNH24, revealing putative single-locus profiles, while hybridization of the same DNA to the minisatellite probes pV47-2, 3'HVR, and per revealed typical multilocus profiles. The numbers of unattributable restriction fragments allowed the maternity and paternity of all individuals to be conclusively determined, despite high levels of band sharing among individuals within breeding groups. These close genetic similarities are a likely consequence of strong philopatry and inbreeding. We report instances of males which are high on the dominance hierarchy but have only a limited reproductive output in comparison with others and males which are subordinate but achieve a significant proportion of fertilizations. Generally these data reveal no consistent relationship between dominance, the frequency of copulations, and parentage among males. We conclude that pukeko highlight some difficulties with conventional explanations for the "function" of dominance.

Short-term effects of fights for social dominance and the establishment of dominant-subordinate relationships on brain monoamines and cortisol in rainbow trout.

We report changes in brain serotonergic, noradrenergic and dopaminergic activity, along with plasma cortisol concentrations, occurring during the initial 24-h period following the establishment of dominant-subordinate relationships in pairs of rainbow trout. Immediately (within 5 min) after the termination of staged fights for social dominance, a large increase in blood plasma cortisol was observed in both fight losers (future subordinate fish) and winners (future dominant fish). In dominant fish, cortisol decreased rapidly (within 3 h) to the level of unstressed controls, while continuing to increase in subordinate fish. At 3 h following fights, the brain serotonergic system was activated in both dominant fish and subordinate fish, at least in some brain regions (telencephalon). This effect was reversed in dominant individuals within 24 h of social interaction, whereas in subordinate fish a substantial activation of the serotonergic system was manifest in all brain regions by 24 h. Similarly, a strong increase in brain catecholaminergic activation was indicated after 24 h of social interaction in subordinate fish, but not in dominant fish. Relationships between plasma cortisol and brain serotonergic and noradrenergic activity in the various experimental groups suggest that these systems influence cortisol secretion under normal conditions and during moderate or short-term stress.

Social grooming in assamese macaques (Macaca assamensis).

Reciprocity and social bonding hypotheses were evaluated as explanations for observed patterns of social grooming in assamese macaques (Macaca assamensis). In accordance with social bonding, females, as the long-term residents of this matrifocal group, groomed each other and juveniles more often than males groomed one another or juveniles. On the other hand, males groomed females more often and for longer durations than females groomed males and, whereas both males and females groomed juveniles more often than juveniles groomed them, juveniles groomed their elders for longer durations. Male grooming of females did not seem directly related to matings as males are single mount ejaculators and use coercive mating tactics. Male grooming of females could not be accounted for in terms of reciprocity; it was not a simple function of dominance. Although both sexes groomed subordinate females more than vice versa, males groomed dominant males more and females groomed subordinate males more than they received grooming from them. Grooming was concluded to function to establish and maintain affiliative social bonds rather than as a specific mechanism to obtain matings or any other specific reciprocation in terms of services or favors.
