Amounts Spent on Engagement Rings Reflect Aspects of Male and Female Mate Quality

Previous research has shown that the qualities of nuptial gifts among nonhumans and marriage-related property transfers in human societies such as bridewealth and dowry covary with aspects of mate quality. This article explores this issue for another type of marriage-related property transfer: engagement rings. We obtained data on engagement ring costs and other variables through a mail survey sent to recently married individuals living in the American Midwest. This article focuses on survey responses regarding rings that were purchased by men acting alone and using only their own funds who then presented the rings while making surprise proposals of marriage (n = 127). Men marrying younger women spent more on rings, as did men who earned more money and whose fiancées earned more money. These findings suggest that the amounts spent on engagement rings, like bridewealth and dowry payments in other societies, reflect aspects of both male and female mate quality.     

Dowry and Public Policy in Contemporary India

In modern Indian political discourse the custom of dowry is often represented as the cause of serious social problems, including the neglect of daughters, sex-selective abortion, female infanticide, and the harassment, abuse, and murder of brides. Attempts to deal with these problems through legislative prohibition of dowry, however, have resulted in virtually no diminution of either dowry or violence against women. In contrast, radically different interpretations of dowry can be found in the literatures of structural-functionalist anthropology, economics, and human behavioral ecology which muster wide-ranging forms of qualitative and quantitative evidence to support functional models of dowry as a form of inheritance or investment in daughters and/or their children. This paper argues that a functionalist perspective on dowry could lead to improved dowry policy, and that an approach based in human behavioral ecology (HBE) is uniquely suited to this task. After reviewing the relevant literature on dowry in South Asia, I discuss current dowry legislation and its limitations. I then develop a behavioral ecology model of Indian dowry and test it with quantitative and qualitative data. I conclude that if dowry legislation is to achieve broad support or bring about effective social change, it must address and support the positive motivations for and effects of dowry and take a targeted approach to dowry violence, which is not uniformly distributed across regions, castes, or social classes.     

Education,gender, and generational change: The transformation of dowry in village Nepal

In a small Bahun village in Gorkha district, West Nepal, in only one generation, there has been a huge shift to educating young women and including them in modernity. Ideologies of ‘gender equality’ in education that are promoted in development programs and discourse, and in Maoist rhetoric, have been powerful drivers behind this. In this paper I highlight the gender and generational dynamics of the changing relationship of women to education in Nepal. I argue that the move to educating women is not a simple one, nor is it necessarily a development success story. The importance placed on educating the younger generation, including women, is also very much tied to local Bahun culture, marriage values and status. Bahun villagers of Ludigaun place great importance on both education and marriage. When combined, I argue, education has in fact become dowry. While there have been transformations in education and other modernising processes, as well as in dowry practices, in this paper I show that they have come to maintain traditional hierarchies and to support the status making of the educated Bahun man.     

From bridewealth to dowry?

Significant amounts of wealth have been exchanged as part of marriage settlements throughout history. Although various models have been proposed for interpreting these practices, their development over time has not been investigated systematically. In this paper we use a Bayesian MCMC phylogenetic comparative approach to reconstruct the evolution of two forms of wealth transfers at marriage, dowry and bridewealth, for 51 Indo-European cultural groups. Results indicate that dowry is more likely to have been the ancestral practice, and that a minimum of four changes to bridewealth is necessary to explain the observed distribution of the two states across the cultural groups.

Studies of Dravidian kinship have neglected the importance of the cross‐sibling relationship. A comparative analysis of data gathered in a Sri Lankan Muslim community shows: (1) normative depictions of cross‐sibling relationships do not reflect or explain actual behavior patterns; and (2) variation in post‐marital cross‐sibling relationships is largely accounted for by the presence or absence and use of the dowry. The overarching purpose is to show that any comprehensive analysis of the Dravidian kinship system must include an analysis of cross‐sibling relationships and dowry practices.     

THE INDIVIDUAL AND TRANSFORMATION OF BRIDEWEALTH IN RURAL NORTH CHINA

Drawing on data collected from longitudinal fieldwork, this article explores how the practice of bridewealth in a north China village has been transformed into a new form of property division within the groom's family and how the bride has replaced her parents as the recipient of bridewealth. At the individual level, this transformation has evolved through a long process during which individual brides and grooms negotiated with their parents over control of bridewealth. A misunderstanding about Western individualism provides village youths with a new ideological tool to justify their relentless extraction of money from their parents. At the level of family life, the changing norm of bridewealth has shaped and in turn has helped to re-shape mate choice, family division, and support for the elderly. These family changes occurred within the context of other social changes at the macro level and are closely linked to the role of the powerful state. While emphasizing the active role of the individual in transforming the practice of bridewealth, an important phenomenon that by and large has been overlooked in most studies of marriage transactions, the article also examines the specific strategies by which individuals exercise their agency, choosing to take advantage of the custom of bridewealth instead of abandoning it when it affords them greater autonomy in mate choice and marriage negotiations.

For Love,Labour, and Lifestyle: European Men Moving to Northeast Brazil

ABSTRACT

This article debates the specific case of the migration of European men to Northeast Brazil and its relation to the creation of intimacy bonds with local women that have been made possible by previous tourist visits. The analysis has the principal objective of understanding the dense framework of social conditions and circumstances that cause the transatlantic mobility of men, and gives particular emphasis to the emotional and marital factors that fuel this type of movement, trying to show that they also migrate for intimacy reasons, and not only for economic reasons as studies based on a neoclassical approach have often seemed to indicate. While central, in these examples of international mobility, the intention to marry is not as determining a factor as the concept of ‘marriage migrations’ would suggest. Poetic motivations related to passion coexist dynamically with a much wider set of (micro)political economy and existential drives, related not only to employment and investment but also to recreation and the minutiae of everyday life. For this reason, it is important to avoid any unicausal schema based on exclusive or dichotomous conceptual frameworks that foreground migration for marital, lifestyle and/or employment motives. The migrations in question tend to be motivated, simultaneously, by the desire for matrimony and to secure assets, and even by what we might call ‘civilisational’ issues. The material that sustains both this and other perspectives presented in the article is the result of a multisited ethnographic fieldwork undertaken in various spaces within Euro-Brazilian configurations of intimacy.     

Characteristics of RecA-independent recombination of plasmids in E. coli cells producing restriction endonuclease EcoRI

The restriction endonuclease EcoRI dependent recombination of compatible plasmids has been studied in RecA cells of Escherichia coli. Plasmid RP4 and the isogenic ColE1 type plasmids pSA14 or pSA25, differing in restriction-modification RM EcoRI genes, have been used to study this type of recombination. EcoRI dependent recombination of plasmids is demonstrated in RecA cells and, thus, is independent of general system of homologous recombination. The classes of recombinant plasmids isolated from RecA cells differ from the classes isolated from wild type cells. Levels of tetracycline resistance conferred by plasmid RP4 are shown to be dependent on the alleles of RecA+ gene, being extremely low in RecA cells. This property is demonstrated to be useful for obtaining the multicopy recombinant plasmids resulting from EcoRI dependent recombination in RecA cells of Escherichia coli.     

Differential fertility in Bangladesh: A path analysis

Abstract

This study attempts to show both theoretically and empirically the causal links between selected background, socioeconomic, and demographic variables, on the one hand, and between these variables and cumulative fertility, on the other. Two distinct models, urban and rural, emerge as a result of a statistical test. In both models, neither wife's nor husband's childhood background is found to have any significant direct effects on fertility. Wife's age, religion, and age at marriage are the common variables which directly affect the number of children ever born. While age and religion bear positive direct effects, age at marriage exerts a negative direct effect. The indirect effect of religion is positive both in the rural and urban area. Both the direct and indirect effects of wife's education on fertility in urban Bangladesh are negative. Husband's education, in contrast, has a positive direct effect in the urban area and no effect at all in the rural area.     

Kinship, Cultural Preference and Immigration: Consanguineous Marriage Among British Pakistanis

This article offers an analysis and interpretation of a high rate of marriage to relatives, especially first cousins, in a sample of second-generation British Pakistanis. It argues that the high rate of such marriage is not a simple reflection of a cultural preference. A better explanation requires an analysis of the factors that influence the decisions and choices of the marriage arrangers in the particular context of Pakistani migration to Britain. The article also underlines the inadequacy of a blanket category 'Pakistani' in relation to marriage patterns and choices. Variation according to region of origin, caste, socio-economic status, and upbringing must be brought into focus to reveal the processes that have generated the pattern, and to offer clues to its likely persistence.     

Social class differences in infant mortality: the problem of competing hypotheses

The authors acknowledge there is no agreed upon explanation of the social class gradient in infant mortality. Some individuals favor explanations based on natural or social selection; some stress the influence of environmental circumstances. Often, theories are presented in articles in such a way that implies an absolute choice is needed. The authors critically examine such a controversial article to point out that erroneous conclusions may be reached and attention may be diverted away from the basic concern of improving infant survival. The controversial article argues that maternal competence is responsible for infant survival. This competence comes from the attributes of intelligence, education, and initiative, which are genetically determined. The attributes are distributed differently between social classes, as evidenced by the social mobility of women in marriage. Class differences in genetically determined maternal competence, therefore, explain the social class gradient in infant mortality. The authors argue that the article is based on the assumption that the issues can be analyzed as mutually exclusive alternatives. For example, the 1st dichotomy is that socially mobile women are either swamped or uplifted by their new environment, or that the women are stratified socially through marriage, on the basis of certain personal attributes such as intelligence, education, health, and height. The 1st option is ignored on the basis that evidence is cited to support the 2nd option, and no allowance is made for the possibility that both explanations may play a part. The differences in opinions about the hypotheses reflect varying political implications. Much well-founded evidence about environmental health risks, for example, are dangerously ignored, such as poor housing or inadequate housing.     

Social and biological determinants of age at first marriage in Taiwan, 1970

Abstract

This study examines the social and biological determinants of age at first marriage in two townships in northern Taiwan, one very rural and traditional and the other urban and modernized. For a sample of 5,707 once‐married women a path analysis was performed in which age at first marriage was considered a function of age, educational attainment, urban origin, premarital labor‐force participation, and age at menarche. Age at menarche, with a positive effect on the dependent variable, was the most important direct cause of age at first marriage. Although exogenous variables associated with modernization (urban origin, educational attainment and younger age) had a positive direct effect on age at first marriage, they also had a negative indirect effect on age at first marriage through their negative direct effect on age at menarche.     

Relationship between muscle fiber types and sizes and muscle architectural properties in the mouse hindlimb

Skeletal muscle fiber and architectural properties both contribute to the functional behavior of a muscle. This study uses discriminant analysis and mathematical modeling to identify the structurally and functionally significant properties. The architectural properties of fiber length, muscle length, and pennation angle are found to be the most structurally significant parameters, whereas fiber length, muscle length, and fiber type distribution are found to be most functionally determining. Architectural speed and fiber type do not appear to be complimentary (i.e., the architectural determinant of sspeed, fiber length, is not associated with fibers of high intrinsic velocity). However, there does seem to be a synergistic relation between the two property classes and force production. Muscles with large physiological cross sectional areas (PCSAs) tend to contain a greater proportion of larger, faster fibers. Structurally or morphologically significant parameters are not always found to have a large functional effect. Pennation angle, though one of the most structurally significant variables, was found to have very little functional effect. © 1994 Wiley-Liss, Inc.     

The influence of female education,labor force participation,and age at marriage on fertility behavior in Bangladesh

Abstract

This paper studies the relationship between three aspects of female status (education, work experience, and age at marriage) and the use of contraception and fertility in Bangladesh. Education is found to be the variable most strongly correlated with use of contraception and is also one of the significant variables explaining fertility behavior. The most important factor explaining fertility behavior is age at marriage. The higher the age at marriage, the lower the fertility, when all other factors are held constant. Work experience has very little or no effect on current use of contraception and fertility.     

Plant sulfite reductase: molecular structure, catalytic function and interaction with ferredoxin

Plant sulfite reductase contains the siroheme and the [4Fe-4S] cluster as catalytically active redox centers and catalyzes the six-electron reductions of sulfite and nitrite using electrons donated from ferredoxin. A heterologous expression of a cDNA for maize sulfite reductase in E. coli has enabled us to produce the wild-type and mutant enzymes. Putative substrate-binding basic residues, located at the siroheme distal side, have been substituted for other residues with neutral or negatively charged side chains. Kinetic studies of the resulting mutant enzymes have demonstrated that substrate specificity for the two anions is remarkably changed by amino acid substitutions at a single site. We have also produced two classes of ferredoxin mutants with less ability to donate electrons to sulfite reductase: one with a defect in the recognition of the partner enzyme and the other with an unfavorable redox property. This article summarizes our knowledge about the structure function relationships of plant sulfite reductase.     

Duration between marriage and first birth and marital instability

This paper considers whether marital instability varies by the duration between marriage and 1st birth among ever-married white and black American women. Analysis of data from the June 1985 Current Population Survey suggests that the duration between marriage and 1st birth has a generally monotonic relationship with the probability of white women separating or divorcing from their 1st marriage; the relationship has remained relatively constant over time. For blacks, no consistent association is found between marital dissolution and the duration between marriage and 1st birth. Black women having a premarital conception and postmarital birth and those having their 1st birth during their 2nd year of marriage have a similarly high risk of dissolution. Conversely, blacks having their 1st birth 8-12 or 25-42 months after marrying have a low probability of dissolution. Childless women and those with premarital births generally has the greatest probability of marital disruption for whites. Racial differences may occur because blacks view the 1st birth and marriage differently than whites. That is, because blacks are much more likely to have premarital births and to have a shorter duration between marriage and 1st birth, blacks and whites in the same 1st birth interval category may be dissimilar and have different values resulting in a differential effect of the timing of the 1st birth on marital instability by race. Caution is needed when interpreting the pattern of association between delayed childbearing (and to a lesser extent, births occuring a few years after marriage) and marital instability. Results for whites were similar at each marriage duration and it is assumed delayed childbearing was not a result of marital instability. Marital instability was expected to have its strongest effect on the timing of the 1st birth during the 1st years of marriage. Marital instability may be partially responsible for the delaying of childbearing among blacks. However, blacks who delay but are married at 1st birth have a relatively low risk of separating or divorcing.     

Making 'bad' deaths 'good': the kinship consequences of posthumous conception

Recent developments in assisted reproduction mean that a child may now be born long after its father's demise. Acts of posthumous conception raise a host of complex ethical and social issues. The article draws attention to these by means of an analysis of the medical, legal, and political commentaries generated by the case of Diane Blood in her dispute with the Human Fertilisation and Embryology Authority, which had prevented her from using her deceased husband's sperm to become pregnant. Analysis of this and similar cases reveals that the desire for offspring following the death of a husband or partner has significant consequences for notions of marriage, paternity, memoriam, and inheritance .The article identifies as an underlying theme in acts of posthumous conception an attempt to ameliorate the grief of a widow, a family, and the wider society by making 'bad' deaths to some extent 'good'. To achieve this transformation the meaning of sperm within reproductive transactions is subject to radical reinterpretations which simultaneously commodotize and sacralize human gametes.     

Exponential growth in age-structured two-sex populations

We consider a continuous age-structured two-sex population model which is given by a semilinear system of partial differential equations with nonlocal boundary conditions and is a simpler case of Fredrickson-Hoppensteadt model. The non-linearity is introduced by a source term, called from its physical meaning, the marriage function. The explicit form of the marriage function is not known; however, there is an understanding among the demographers about the properties it should satisfy. We have shown that the homogeneity property of the non-linearity leads to the fact that the system supports exponentially growing persistent solutions using a general form of the marriage function and its properties. This suggests that the model can be viewed as a possible extension of the one-sex stable population theory to monogamously mating two-sex populations.     

Sexual Desire,Piety, and Law in a Javanese Pesantren: Interpreting Varieties of Secret Divorce and Polygamy

Very little anthropological research has explored the polygamous worlds of women in Indonesia's traditional Islamic boarding schools known as pesantren. These traditional schools are patriarchal institutions that teach women to be ideal Muslims according to male-defined notions of shari'ah-based piety that construct polygamy as normative. This article challenges dominant discourses on polygamy, which are mostly concerned with public protest and feminist agendas that seek to have the practice banned, and instead reveals an agentive side of women in polygamous marriages. It examines the experiences of a group of pesantren women whose actions transgress state and Islamic laws on marriage and divorce in their endorsement of polygamous union and nikah batin (Sufi spiritual marriage). It builds on feminist arguments that recognise female agency in polygamy by considering the legal ambiguity surrounding secret and informal divorce and polygamous practices initiated by women restricted from obtaining legal divorces for socio-cultural reasons. In doing so, it further considers some aspects of a notion of a woman-centric polygamy that includes polyandry, which women create based on their understanding that Islam acknowledges women's sexual rights in marriage.
