There has been a steady trend of adopting children from other countries. Families who adopt children internationally are faced with not only the acknowledgement of the adoption but the recognition of the birth culture. Thirty four families were surveyed to assess issues regarding the relevance, frequency, and means of acknowledgement of the adoption and birth culture. Findings are reported with suggestions for adoption professionals included. 相似文献

Cultural norms may restrict the demonstration of intimacy between men, such that male adults are relatively unlikely (in comparison to females) to display affection in public by hugging or putting hands around one another's waists. Study 1 examined via a role playing technique how the gender composition of a dyad and types of friendship influence tactile greetings. Males displayed less physical intimacy with male friends than with female (platonic or dating) friends and less than females displayed with their same-sex friends. Study 2 examined subjects' perceptions of and attributions about reciprocal touch. Male-male behavior was rated as less normal as a function of the level of physical touch (going from no touch, hugging, to arms around the waist). The normalcy rating of opposite-sex pairs did not vary as a function of the touch manipulation, but female, same-sex pairs' behavior was rated as less normal in the arms around the waist than in either the no touch or hug conditions. In the male same-sex pairs, hugging was seen as more likely to reflect a sexual relationship than no touch, while arms around one another's waist was rated as even more likely to represent a sexual relationship. It was suggested that homophobia, the fear of appearing or being homosexual, may operate to inhibit physical intimacy between men. 相似文献

Assessing the Relationship Between Environmental Lead Concentrations and Adult Blood Lead Levels 总被引:2,自引:0,他引:2
This paper presents a model for predicting blood lead levels in adults who are exposed to elevated environmental levels of lead. The model assumes a baseline blood lead level based on average blood lead levels for adults described in two recent U.S. studies. The baseline blood lead level in adults arises primarily from exposure to lead in diet. Media-specific ingestion and absorption parameters are assessed for the adult population, and a biokinetic slope factor that relates uptake of lead into the body to blood lead levels is estimated. These parameters are applied to predict blood lead levels for adults exposed to a hypothetical site with elevated lead levels in soil, dust and air. Blood lead levels ranging from approximately 3-57 μg/dl are predicted, depending on the exposure scenarios and assumptions. 相似文献

Nearest–neighbour balance is considered a desirable property for an experiment to possess in situations where experimental units are influenced by their neighbours. This paper introduces a measure of the degree of nearest–neighbour balance of a design. The measure is used in an algorithm which generates nearest–neighbour balanced designs and is readily modified to obtain designs with various types of nearest–neighbour balance. Nearest–neighbour balanced designs are produced for a wide class of parameter settings, and in particular for those settings for which such designs cannot be found by existing direct combinatorial methods. In addition, designs with unequal row and column sizes, and designs with border plots are constructed using the approach presented here. 相似文献
