Pregnancy discrimination exhibits a coherent social logic. The exclusion of women from employment on the basis of pregnancy perpetuates the sexual division of productive and reproductive labor, thereby confirming women's second class status in the work force. The Pregnancy Discrimination Act of 1978 amends Title VII of the Civil Rights Act of 1964 by clarifying that the Act's proscription of se...

Background: Sexual abuse and harassment are among the major threats to labor children, especially girls, which can be associated with anxiety and loneliness. The current study aimed to investigate the effect of Gestalt play therapy on anxiety and loneliness in Afghan female labor children with sexual abuse histories. Methods: This was a Single Case Research Design (SCRD) study of the AB model....

As is well known (and seen in a previous post), compilers optimize unsigned division by constants into multiplication by a "magic number." But not all constants are created equal, and approximately 30% of divisors require magic numbers that are one bit too large, which necessitates special handling (read: are slower). Of these 30%, slightly less than half (46%) are even, which can be handled at...

The division of labor is an important component of the organization of human society. However, why this division evolved in hominids requires further investigation. Archeological evidence suggests that it appeared after the emergence of Homo sapiens and contributed to the great success of our species. We develop a mathematical model to investigate under what conditions division of labor should ...

Sexual reproductive behavior has a necessary social coordination component as willing and capable partners must both be in the right place at the right time. It has recently been demonstrated that many social organizations that support sexual reproduction can evolve in the absence of social coordination between agents (e.g. herding, assortative mating, and natal philopatry). In this paper we ex...

In this paper we propose a mathematical model for studying the phenomenon of division of labor in ant colonies. Inside this model we investigate how simple task allocation mechanisms can be used to achieve an optimal division of labor. We believe the proposed model captures the essential biological features of division of labor in ant colonies and is general enough to study a variety of differe...

This study aims to shed a light on children’s pragmatic development by examining Mandarin-speaking requests in interactions with their parents. It is found that children between 24 and 36 months old appear use various request forms, primarily simple imperatives WANT statements. A closer examination reveals prefer activity-based while both primary forms are unstructured daily conversations. The ...
