Evidence to Suggest that Copulatory Vocalizations in Women Are Not a Reflexive Consequence of Orgasm

The current studies were conducted in order to investigate the phenomenon of copulatory vocalizations and their relationship to orgasm in women. Data were collected from 71 sexually active heterosexual women (M age = 21.68 years ± .52) recruited from the local community through opportunity sampling. The studies revealed that orgasm was most frequently reported by women following self-manipulation of the clitoris, manipulation by the partner, oral sex delivered to the woman by a man, and least frequently during vaginal penetration. More detailed examination of responses during intercourse revealed that, while female orgasms were most commonly experienced during foreplay, copulatory vocalizations were reported to be made most often before and simultaneously with male ejaculation. These data together clearly demonstrate a dissociation of the timing of women experiencing orgasm and making copulatory vocalizations and indicate that there is at least an element of these responses that are under conscious control, providing women with an opportunity to manipulate male behavior to their advantage

Understanding the effects of socioeconomic status along the breast cancer continuum in Australian women: A systematic review of evidence

© 2017 The Author(s). Background: Globally, the provision of equitable outcomes for women with breast cancer is a priority for governments. However, there is growing evidence that a socioeconomic status (SES) gradient exists in outcomes across the breast cancer continuum - namely incidence, diagnosis, treatment, survival and mortality. This systematic review describes this evidence and, because of the importance of place in defining SES, findings are limited to the Australian experience. Methods: An on-line search of PubMed and the Web of Science identified 44 studies published since 1995 which examined the influence of SES along the continuum. The critique of studies included the study design, the types and scales of SES variable measured, and the results in terms of direction and significance of the relationships found. To aid in the interpretation of results, the findings were discussed in the context of a systems dynamic feedback diagram. Results: We found 67 findings which reported 107 relationships between SES within outcomes along the continuum. Results suggest no differences in the participation in screening by SES. Higher incidence was reported in women with higher SES whereas a negative association was reported between SES and diagnosis. Associations with treatment choice were specific to the treatment choice undertaken. Some evidence was found towards greater survival for women with higher SES, however, the evidence for a SES relationship with mortality was less conclusive. Conclusions: In a universal health system such as that in Australia, evidence of an SES gradient exists, however, the strength and direction of this relationship varies along the continuum. This is a complex relationship and the heterogeneity in study design, the SES indicator selected and its representative scale further complicates our understanding of its influence. More complex multilevel studies are needed to better understand these relationships, the interactions between predictors and to reduce biases introduced by methodological issues

Evidence to Suggest That Teeth Act as Human Ornament Displays Signalling Mate Quality

Ornament displays seen in animals convey information about genetic quality, developmental history and current disease state to both prospective sexual partners and potential rivals. In this context, showing of teeth through smiles etc is a characteristic feature of human social interaction. Tooth development is influenced by genetic and environmental factors. Adult teeth record environmental and traumatic events, as well as the effects of disease and ageing. Teeth are therefore a rich source of information about individuals and their histories. This study examined the effects of digital manipulations of tooth colour and spacing. Results showed that deviation away from normal spacing and/or the presence of yellowed colouration had negative effects on ratings of attractiveness and that these effects were markedly stronger in female models. Whitening had no effect beyond that produced by natural colouration. This indicates that these colour induced alterations in ratings of attractiveness are mediated by increased/decreased yellowing rather than whitening per se. Teeth become yellower and darker with age. Therefore it is suggested that whilst the teeth of both sexes act as human ornament displays, the female display is more complex because it additionally signals residual reproductive value

Evidence to Suggest that Women’s Sexual Behavior is Influenced by Hip Width Rather than Waist-to-Hip Ratio

Waist-to-hip ratio (WHR) is an important ornament display that signals women’s health and fertility. Its significance derives from human development as a bipedal species. This required fundamental changes to hip morphology/musculature to accommodate the demands of both reproduction and locomotion. The result has been an obstetric dilemma whereby women’s hips are only just wide enough to allow the passage of an infant. Childbirth therefore poses a significant hip width related threat to maternal mortality/risk of gynecological injury. It was predicted that this would have a significant influence on women’s sexual behavior. To investigate this, hip width and WHR were measured in 148 women (M age = 20.93 + 0.17 years) and sexual histories were recorded via questionnaire. Data revealed that hip width per se was correlated with total number of sexual partners, total number of one night stands, percentage of sexual partners that were one night stands, number of sexual partners within the context of a relationship per year sexually active, and number of one night stands per year sexually active. By contrast, WHR was not correlated with any of these measures. Further analysis indicated that women who predominantly engaged in one night stand behavior had wider hips than those who did not. WHR was again without effect in this context. Women’s hip morphology has a direct impact on their risk of potentially fatal childbirth related injury. It is concluded that when they have control over this, women’s sexual behavior reflects this risk and is therefore at least in part influenced by hip width

Contemporary and Historical Evidence to Suggest that Women’s Preference for Age at Birth of First Child Remains Consistent Across Time

Women’s ability to reproduce is restricted by menarche and menopause. First children are, however, not typically born until some years after the onset of puberty. Other factors therefore contribute towards this delay. In this context, women’s hips do not reach full adult form until they are in their mid-20s. Therefore, physiological and morphological factors appear to determine an optimum age-range for reproduction. The following studies were conducted in order to investigate this hypothesis. Study 1 asked nulliparous women questions about ages at which particular life events related to reproduction should ideally occur. This revealed their preferred age at birth of first child to be approximately 27 years old. Study 2 replicated these findings and further showed that women with children actually had their first child at a very similar age (27.93 [±0.79]). Findings from Study 3 were also remarkably consistent (28.15 [±0.39]). Study 4 examined the 1901 UK Census record and incorporated an analysis of the influence of wealth. Middle class women were on average 24.88 (±0.22) years old at the birth of their first child. Poor women were on average 23.50 (±0.20) years old. These figures at least approximate to findings from Studies 1–3, which is noteworthy given that modern contraceptive methods were not widely available at the time. It is concluded that female strategies to delay giving birth to their first child until they are of an age that approaches or coincides with their full hip maturation are enduring across time

"Now the people are like the Lord": Local effects of revolutionary reform in a Tigray village, northern Ethiopia

The thesis examines aspects of social change in rural Tigray, northern Ethiopia. It is based on fieldwork conducted between February 1993 and February 1995 in two villages located on the south central highland plateau: Enda Mariyam, and Tegula. The majority of fieldwork was conducted in Enda Mariyam - a village of some 228 farming households - and spanned two complete agricultural years. The thesis considers the local implications of reform measures implemented by nationalist rebels - the Tigray People's Liberation Front - as part of a revolutionary agenda for the transformation of "traditional" Ethiopian peasant society. These measures included, most notably, land tenure reform, as well as changes in customary law and the re-organisation of rural administration. In addition, campaigns were mounted aimed at modifying certain aspects of peasant practice. In the context of a village-based ethnography, the thesis aims to qualify the most significant effects of these measures on social life and livelihoods. A key concern is how reform measures have affected the relationship between subsistence-oriented production, social organisation, and social stratification. In a setting where agricultural inputs - including land, oxen, and seed - are scarce, differential abilities amongst farming households to access agricultural inputs informs the pattern of social relationships. In this context, land reform is intimately linked to changes in the dynamics of wealth differentiation and social stratification in the village. The implications for the position of "big men" and cultural notions of status-honour are considered. Together with land reform, reform of customary law in the area of marriage and divorce has wrought subtle but important changes in marriage and divorce practices, and the nature of intra-household relationships. It is argued that public campaigns for the "emancipation" of women have probably had less effect on the ability of women to exert power within marriage, than the economic penalties that men now face upon divorce. Attempts to modify peasant religious practice are also examined, including efforts to minimise the number of holidays in the Ethiopian Orthodox calendar. The outcome of these attempts is explored in terms of notions of disaster and risk, the traditional authority of the Church, and the fragmentation of consensus around religious practice in the village
