Kinship and Population Subdivision

The coefficient of kinship between two diploid organisms describes their overall genetic similarity to each other relative to some base population. For example, kinship between parent and offspring of 1/4 describes gene sharing in excess of random sharing in a random mating population. In a subdivided population the statistic F _st describes gene sharing within subdivisions in the same way. Since F _st among human populations on a world scale is reliably 10 to 15%, kinship between two individuals of the same human population is equivalent to kinship between grandparent and grandchild or between half siblings. The widespread assertion that this is small and insignificant should be reexamined.

Ageing-driven pension reforms

This paper stems from the observation that there are two worldwide trends, pension reform and population ageing, and asks whether the two may be related. Exploring the cases of pension reform in different countries, we find that, although they are very different, the cases share a common characteristic: they shift risks away from workers towards those who are retired. Furthermore, population ageing, by increasing the weight of the elderly relative to working generations, raises the price of intergenerational risk sharing. Combining these findings, we argue and show formally that pension reform can be seen as a welfare-best response to population ageing.     

Voluntary income sharing and the design of unemployment insurance

This paper uses a model of search unemployment to discuss the interaction between publicly provided insurance and informal insurance through voluntary income sharing, e.g., between spouses. Income sharing reduces the optimal level of public unemployment insurance. While it is always individually rational for partners to share income, the effect of voluntary income sharing on welfare will be negative unless partners can either observe each other's search behavior or are sufficiently altruistic towards each other. The model is also used to examine a family-based policy. The welfare gains from using such policy are argued to be small. Received: 14 December 2000/Accepted: 5 November 2001     

Inter- and intraspecific interactions among larvae of specialist and generalist parasitoids

Intra- and interspecific larval interactions that take place in a host body were investigated for two tachnid fliesEpicampocera succincta andCompsilura concinnata (Diptera: Tachinidae) parasitizingPieris butterfly larvae.E. succincta, a specialist onPieris butterflies, showed contest-type intraspecific competition, eliminating all the other conspecific larvae. On the other hand, an extreme generalist parasitoidC. concinnata exhibited scramble-type competition, sharing the host with other conspecifics and suffering reduced body size as a result. However, when these two species occurred together in a single host,C. concinnata had a much higher chance of survival. Moreover,C. concinnata could often survive in the presence of a parasitoid waspCotesia glomerata (Hymenoptera: Braconidae) whileE. succincta could not. The high tolerance ofC. concinnata could be attributable to its being an extreme generalist: To attack and survive on many different hosts, one has to be able to deal with various competitors. The competitive inferiority of the specialistE. succincta, on the other hand, may be a result of relatively recent encounter with, those competitors.

Gewalt in ihren Deutungen

The article addresses relations between violence and culture. One central characteristic of violence is its culturality. Violent interactions, as well as fantasies of violence, depend on cultural patterns of meaning. A certain act of violence can be interpreted differently from one culture to the other. At the same time, cultures generate specific forms of violence. Violence is imagined, enacted and interpreted in cultural opportunity spaces. These do not necessarily limit violence to the forms already known, but they do shape their developments. The culturality of violence is countered by the possibility of its purposive culturalization. Violent action is open to interpretation, this is, multiple and disparate meanings can be given to a certain act. Also, violence is tightly connected with power. These two characteristics predestine violence as an object of conflicts about definitions. Certain meanings of violence can be propagated and thus used politically, which may also influence further violent actions. Confronting these two relations between violence and culture, the problem is addressed as to how sociological research on violence can, on the one hand, take into account the culturality of violence without, on the other hand, adopting purposeful culturalizations of violent phenomena by political forces, instead of probing into them analytically.     

The Myth of Openness and Secrecy in Intimate Relationships: The Case of Spouses of Mixed-Orientation Marriage

The phenomenon of mixed-orientation marriages, in which one of the partners is straight and the other is non-straight, is invisible, yet not insignificant. Focusing on gay and bisexual men who are married to straight women, this article was designed to explore one of the essential themes in their relationship: the dynamics between secrecy and openness regarding the men’s sexual orientation and gay practices. Based on the phenomenological paradigm, 38 men and eight women of mixed-orientation marriages in Israel were interviewed and shared their subjective life reality. Six patterns of secrecy and openness were identified, including complete secrecy, conspiracy of silence, initiated concealment (of the husband and wife), disloyalty/violation of the agreement, selective sharing, and complete openness. The findings challenge the idea that secrecy is detrimental and openness is beneficial in the context of mixed-orientation marriages. Findings are discussed within the framework of the dialectical approach.     

Was ist neu am Neo-Institutionalismus?

This paper discusses the specific characteristic of the new institutionalism in comparison with other dominant approaches within US organization studies. The argument is led by the theses that within contingency theory, resource dependency theory, and population ecology the economic environment is of utmost importance and that the economy is regarded as the major sphere of reference, either implicitly or explicitly. A multi-contextual embeddedness between organizations and society is hardly to be found within these theoretical approaches. The new institutionalism departs from this line of thinking, because it considers a variety of different environmental realms and sees organizations as always being embedded within a societal context. I regard this as the central new and distinguishing feature of the new institutionalism. The aim of the paper is to show this distinguishing difference between the new institutionalism and the three approaches.     

Categorization in concentration camps as a collective fate: a comparison of homosexuals, Jehovah's Witnesses and political prisoners

Using socio-historical data some critical features of Nazi Concentration Camps are discussed: uniqueness vs. normality; extermination vs. re-education of gay prisoners. The special fate of the Pink Triangle in comparison to other non-Jewish victims is demonstrated. The determinative qualities of life and death conditions in the camps are: the National Socialist interpretation of the prisoner category; the repressive content of social control; the marginalisation in general society. The relative strength of a single influence cannot be separated one from the other.     

Active female courtship behavior and male nutritional contribution to female fecundity in Bruchidius dorsalis (Fahraeus) (Coleoptera: Bruchidae)

Mating behavior and the male's contribution to female fecundity were studied in the bean weevil Bruchidius dorsalis (Fahraeus) (Coleoptera: Bruchidae) in comparison with two other species, Callosobruchus chinensis (which infests stored beans) and Kytorhinus sharpianus (which feeds on wild legumes). Only females of B. dorsalis showed multiple mating and characteristic precopulatory behavior that appeared to solicit the male's nutritious secretion. In contrast, all females of the other two species did not copulate multiply and did not show such precopulatory behavior. In B. dorsalis, the decrement of male body weight just after copulation indicated that seminal fluid weighing as much as approximately 7% of the male's body weight was transferred to the female. Fecundity was more than eight times higher in females that had copulated ten times than in females that had copulated only once, indicating that males paid most of the nutritional cost of egg production. These facts suggest that the sex role is reversed in B. dorsalis. Received: May 22, 1998 / Accepted: July 19, 1999     

Women's experiences of participation in a pregnancy and postnatal group incorporating yoga and facilitated group discussion: A qualitative evaluation

BackgroundThis paper reports on a small qualitative research study which explored women's experiences of participation in a pregnancy and postnatal group that incorporated yoga and facilitated discussion. The group is offered through a community based feminist non-government women's health Centre in Northern NSW Australia.QuestionThe purpose of the research was to explore women's experiences of attending this pregnancy and postnatal group.MethodsAn exploratory qualitative approach was used to explore women's experiences of attending the group. Fifteen women participated in individual, in-depth face-to-face interviews. Interviews were recorded and transcribed verbatim. Thematic analysis was undertaken to analyse the qualitative data.FindingsSix themes were developed, one with 3 subthemes. One theme was labelled as: ‘the pregnancy and motherhood journey’ and included 3 sub-themes which were labelled: ‘preparation for birth’, ‘connecting with the baby’ and ‘sharing birth stories.’ The other five themes were: ‘feminine nurturing safe space’, ‘watching and learning the mothering’, ‘building mental health, well-being and connections’, the “group like a rock and a seed’ and ‘different from mainstream’.ConclusionThis research adds to the overall body of knowledge about the value of yoga in pre and postnatal care. It demonstrates the value of sharing birth stories and the strong capacity women have to support one another, bringing benefits of emotional and social well-being, information, resources and support derived from group based models of care.     

Old-age security, religious celibacy, and aggregate fertility in a Tibetan population

Using the family system as a framework, this study investigates the connection between old-age security concerns and aggregate fertility in Sama and Lho, two ethnically Tibetan villages of highland Nepal. The microdemographic approach reveals a difference in family systems between the two villages that results in Sama having a significantly lower level of fertility than Lho. The key difference lies in the practice of Sama’s (but not Lho’s) householders of designating a daughter to be a nun, a strategy meant to retain female labour within the household and thereby guarantee a caretaker in old age. Although the effect of this practice on individual fertility is unclear, the comparison with Lho reveals how it sharply curtails aggregate fertility by preventing nearly one in five women from marrying. In this case the motivation to ensure old-age security acts as an unintentional preventive check on population growth. Comparisons with other societies illustrate how the population of Sama combines elements of both the historical European and Asian demographic experiences.

Dutch gay emancipation history (1911-1986)

The Dutch homosexual movement is one of the oldest and most influential in the world. The aim of this article is to describe how this success can be explained both by some specific characteristics of Dutch society and ideologies, strategies, and tactics as developed by the gay movement. Although it is always risky to make a comparison with other countries and the homosexual movements there, I try to point out briefly some distinct differences and similarities.     

Role relationships: lesbian perspectives

This questionnaire study of 140 lesbians, 70 couples who have lived together for one or more years, explores equality and role relationships. We predicted that lesbians would achieve partnerships characterized by equality and freedom from traditional butch-femme role playing. Financial sharing and decision-making were found to be characterized by high degrees of equality. Household responsibilities tended to be performed individually, but no role-playing was evident. Sexual intimacy items indicated less perceived equality than other areas. And overall, some partners were viewed as unequal. The variables of age, income, education, occupation, assets, and years living together did not explain the inequality observed.     

Comparison and fairness in family planning]

There are two kinds of comparison in family planning (FP) practice. First, people compare the number of children they have with their desired family size. Second, people compare their number of children with other's. The extent of their satisfaction from the comparison often depends on their expectation. And people's expectation about their family size may have an impact on the level of fertility. One task in a FP program is to regulate people's objects for comparison and to reduce the number of children they expect to have. But, changes in people's desired number of children are largely dependent upon the socio economic charges which can not be achieved in short time. Therefore, it would be more advisable to direct people to compare their fertility behavior with those of couples who have only one child, rather than those who have 3 or 4. Satisfaction with family size also comes from a feeling of fairness. People not only look at what they get, but also at what others get. Fairness and justice in FP program implementation is important. If those who violate local birth control policies and regulations are not properly punished, other people would feel that the situation is unfair and they would regret that they did not do the same. The pressure brought by over-population to socio-economic development has been gradually felt by most people. But, it is still difficult to have them strictly observe the present fertility regulation policy. If restrictions of various kinds are enforced and education and publicity are used, people will feel that they are being treated fairly. This will facilitate the promotion of the FP program.     

Midwife-led continuity of care improved maternal and neonatal health outcomes in north Shoa zone,Amhara regional state,Ethiopia: A quasi-experimental study

BackgroundIn a low-resource setting, information on the effect of midwife-led continuity of care (MLCC) is limited. Therefore, this study aimed to determine the effect of MLCC on maternal and neonatal health outcomes in the Ethiopian context.MethodA study with a quasi-experimental design was conducted from August 2019 to September 2020 in four primary hospitals of the north Shoa zone, Amhara regional state, Ethiopia. A total of 1178 low risk women were allocated to one of two groups; the midwife-led continuity of care (MLCC or intervention group) (received all antenatal, labour, birth, and immediate postnatal care from a single midwife or backup midwife) (n = 589) and the Shared model of care (SMC or comparison group) (received care from different staff members at different times) (n = 589). The two outcomes studied were Spontaneous vaginal birth and preterm birth. Outcome variables were compared using multivariate generalized linear models (GLMs) and reported using adjusted risk ratios (aRR) with 95% confidence intervals.FindingsWomen in MLCC were, in comparison with women in the SMC group more likely to have spontaneous vaginal birth (aRR of 1.198 (95% CI 1.101–1.303)). Neonates of women in MLCC were in comparison with those in SMC less likely to be preterm (aRR of 0.394; 95% CI (0.227–0.683)).ConclusionIn this study, use of the MLCC model improved maternal and neonatal health outcomes. To scale up and further investigate the effect and feasibility of this model in a low resource setting could be of considerable importance in Ethiopia and other Sub-Saharan Africa countries.     

The Greek mirror: the Uranians and their use of Greece

The Uranians comprised a loosely knit group of British and American homosexual poets writing between approximately 1880 and 1930, sharing a number of basic cultural and literary assumptions derived on one hand from Walter Pater, and on the other from Walt Whitman. Although they used Oriental, Christian and other motifs, one of the major elements many shared was a use of various allusions and themes from ancient Greece, including paganism, male companionship or intimate friendship (which was not defined in terms of sameness), and democracy and a natural aristocracy of virtue, which they applied to the concerns of their own society and era. The model of male relationships which they advocated (and in at least some cases practiced) was almost uniformly asymmetrical, either by age or class, or both. In addition to their poetry, various theoretical writings by members of the group are also involved in the discussion, and this article argues that these historical/ literary allusions and themes should not be understood as means of evasion which allowed them to write of tabooed subjects safely, but as part of a consciously adopted artistic/cultural strategy for homosexual emancipation. It also suggests that their arguments should be reexamined as a corrective to the present egalitarian model of homosexuality.     

An examination of referent selection processes underlying job satisfaction

Using two different methods of assessment, the goal of the present research was twofold: (1) to examine the relative influence that different standards of comparison have in determining satisfaction with various job facets; and (2) to examine the relative consistency of each standard's influence across job facets. According to both direct reports and the strength of empirical relationships, the results indicated that some standards of comparison were stronger predictors of facet satisfaction than others. The consistency of a standard's influence or predictive power depended on the particular standard of comparison under consideration. Some standards were consistently strong or consistently weak predictors of facet satisfaction, regardless of the particular job facet. However, for other standards of comparison, the amount of predictive influence depended on the particular job facet. Within the context of discrepancy-based theories of job satisfaction, results are discussed in terms of their comparability across the two different methods of assessment, and the directions they suggest for future research.
