This study investigated the differences in parental attitudes toward cross gender behavior in children. It was hypothesized that cross gender behavior would be seen as more acceptable for girls than boys, that this effect would be more prominent in fathers than in mothers, and that parental acceptance of cross gender behavior would decrease as a child got older. Instruments were sent to both pa...

Numbers of nematodes recovered per culture varied greatly among five species cultured on carrot disks. Radopholus similis and Pratylenchus vulnus showed the highest population densities, with 23,400-fold and 16,600-fold increases, respectively, in 90 days. Final populations of P. thornei and Zygotytenchus guevarai were similar but lower than those of R. similis and P. vulnus. The population of ...

Character displacement is the process by which traits evolve in response to selection to lessen resource competition or reproductive interactions between species. Although character displacement has long been viewed as an important mechanism for enabling closely related species to coexist, the causes and consequences of character displacement have not been fully explored. Moreover, character di...

As judged by any sentinel marker, ESHRE houses the most successful journals in reproductive health and disease, namely,Human Reproduction Update,Human Reproduction andMolecular Human Reproduction (MHR). This position has been achieved by continual publication of only the highest quality articles and constant innovation. With the change in editorship of all three ESHRE journals in 2013, the oppo...

eurasian perch, perca fluviatilis l., is one of the most important species in european freshwater aquaculture and probably one of most important of cold freshwater species in nearest future. the aim of this study was to test the ovaprim in artificial reproduction in eurasian perch in two temperatures (12 and 14°c) with using new oocyte maturation stage system. the results obtained in present st...

a two-year laboratory study on the biology (including self-fertilization) of bulinus truncatus, the intermediate host of schistosoma haematobium, s. bovis and paramphistomum microbotrium in iran, has revealed information on the longevity, reproduction, hatchability rate, hatching time during various months of the year, and growth and mortality rates of this snail. it was found that the reproduc...

A new structure learning approach for Bayesian networks (BNs) based on asexual reproduction optimization (ARO) is proposed in this letter. ARO can be essentially considered as an evolutionary based algorithm that mathematically models the budding mechanism of asexual reproduction. In ARO, a parent produces a bud through a reproduction operator; thereafter the parent and its bud compete to survi...

rapid development in assisted reproductive techniques along with relieving the pain of childlessness has brought new ethical and policy dilemmas. posthumous assisted reproduction is the most challenging, difficult and sensitive issue to be discussed ethically and religiously. in this paper the acceptability of the posthumous reproduction in islamic contexts is evaluated and major concerns like ...
