in recent years, preservation of fertility in women has been of great importance, especially in patients exposed to deleterious conditions on fertility. thus, cryopre-servation of human gametes, embryos and ovarian tissue has become an essential part of assisted reproduction. this approach limits the number of embryos transferred, while supernumerary oocytes and/ or embryos can be used in subse...

to establish the behavioral indicator of reproductive success of female captive alpine musk deer(moschus sifanicus), the focal sampling was used to record the individual behaviors at xinglongshan muskdeer farm (xmdf), gansu province, china. conducted between june 2008 and january 2009, 31 adultfemales were observed, of which 26 had successfully bred in the previous year, and five of which wereb...

in recent decades, the concept of cultural capital has created a lot of scientific studies over the world in the sociology of education. these studies mainly based on the two models: bourdieu's cultural reproduction and dimaggio's cultural mobility. these have achieved different results. this study aimed at evaluating the theoretical models in an empirical condition. middle and high school stud...

Fifteen years ago, DeLone and McLean published their original model of IS success, which received considerable attention in the literature. Given the widespread acceptance of the model, we conducted a meta-analysis to determine whether the model had been validated by research studies reported in the literature. By aggregating the results of 52 empirical studies that examined relationships withi...

The relationship between foraging success and reproduction is commonly assumed to be linear in theoretical investigations. Although the exact relationship (e.g., linear or nonlinear) does not influence qualitative conclusions of models under some assumptions, an inclusion of individual behavioral variation can make it otherwise due to Jensen's inequality. In particular, a mechanism that stabili...

Reproductive success of females in iteroparous species usually increases early in life, then remains constant or declines. The restraint hypothesis suggests that primiparous females limit their 1st reproduction in order to avoid future costs to survival, reproduction, or both, whereas constraint indicates that primiparous females are limited in their 1st reproductive attempt either because they...
