In sub-Saharan Africa, the exchange of sex for material support-labeled "transactional sex" by Western observers--is claimed by some to be a major driver of the AIDS pandemic. Transactional sex is described as akin to prostitution, a degraded form of sexual expression forced on vulnerable women by economic desperation. Using evidence from rural Malawi, we demonstrate that patron-client ties and...

growth and reproductive attributes were determined for capoeta damascina, an endemic fish species from west of iran. a total of 147 specimens of both sexes were sampled monthly from november 2008 to october 2009. the overall sex ratio was female biased. males were aged 0-4 years and females 0-5 years. the von bertalanffy growth parameters were estimated as; linf=34.81 cm, k=0.27 year-1, t0=-0.6...

A Markovian susceptible --> infectious --> removed (SIR) epidemic model is considered in a community partitioned into households. A vaccination strategy, which is implemented during the early stages of the disease following the detection of infected individuals is proposed. In this strategy, the detection occurs while an individual is infectious and other susceptible household members are vacci...

In this paper, the question arises as to whether modern social theories about education make sense, among other things, of identity person who is a carrier disability autism. The critical view for common educational "place" regarding specificity lifelong attempted be understood through deficit in skills and with dominant characteristic invisible autism examined based on Goffman's theoretical vi...

Abstract This article uses Taiwan as an example to argue that reproductive justice for gay men should be conceptualised within social, legal, and political contexts. is the first Asian country legalise same‐sex marriage, yet law favours heterosexual couples denies LGBTQ+ rights. Thus, Taiwanese seek third‐party reproduction overseas become parents. exemplifies men's unequal conditions from a no...

The Bethe-Salpeter amplitudes of the bound states formed by two scalar particles with unequal masses are analyzed in the massive scalar particle exchange ladder model. The norms of the amplitudes are calculated numerically, and it is confirmed that the norm vanishes for the bound state corresponding to the complex eigenvalue of the coupling constant. The behaviour of the Bethe-Salpeter amplitud...
