This article examines Russia's position on the Senkaku/Diaoyu dispute. It focuses particularly on the claim that Russia and China are forming an anti-Japanese territorial front. Looking closely at official statements and actions, as well as Russian-language media and scholarship, it finds that Russia, while retaining a position of formal neutrality, clearly considers China's claims more favourably. While this could be seen to have alarming implications by arraying China and Russia on one side against Japan and the USA on the other, the article also finds that Russia's support is not without qualifications and that its place in the conflict is not yet entrenched. 相似文献

Adolescent Girls’ Experiences and Gender-Related Beliefs in Relation to Their Motivation in Math/Science and English 总被引:1,自引:0,他引:1

Although the gender gap has dramatically narrowed in recent decades, women remain underrepresented in many science, technology,
engineering, and mathematics (STEM) fields. This study examined social and personal factors in relation to adolescent girls’
motivation in STEM (math/science) versus non-STEM (English) subjects. An ethnically diverse sample of 579 girls ages 13–18 years
(M = 15) in the U.S. completed questionnaires measuring their academic achievement, ability beliefs, values, and experiences.
Social and personal factors were hypothesized to predict motivation (expectancy-value) differently in math/science (M/S) and
English. Social factors included perceived M/S and English support from parents and peers. Personal factors included facets
of gender identity (felt conformity pressure, gender typicality, gender-role contentedness), gender-related attitudes, and
exposure to feminism. In addition, grades, age, parents’ education, and ethnicity were controlled. Girls’ M/S motivation was
positively associated with mother M/S support, peer M/S support, gender-egalitarian beliefs, and exposure to feminism; it
was negatively related to peer English support. Girls’ English motivation was positively associated with peer English support
as well as felt pressure from parents; it was negatively related to peer M/S support and felt peer pressure. The findings
suggest that social and personal factors may influence girls’ motivation in domain-specific ways. 相似文献

Residential fires are a significant cause for morbidity and mortality in the United States. Death is often the result of soot and smoke inhalation causing carbon monoxide (CO) toxicity. The approximate lethal level of carboxyhemoglobin (COHb) in healthy adults has been well described. However, a significant number of medical examiner cases involve infirmed decedents, often elderly, with complex cardiovascular disease burdens. It is well known that death in these cases will occur at sublethal levels of COHb; however, increased lethality has been largely documented via anecdotal experience and lacks quantification. Fifty-five cases were identified where death resulted from smoke and soot inhalation suffered in a residential fire. The control group, with no cardiovascular disease, had an age-adjusted mean COHb level of 61.6% at the time of death. Presence of hypertensive cardiovascular disease showed a 30% reduction in COHb (age-adjusted mean 43.2%), atherosclerotic disease showed a 33% reduction (age-adjusted mean 41.5%), and combined disease presentation accounted for 41% reduction (age-adjusted mean 36.3%). When controlling for age, atherosclerotic and hypertensive cardiovascular diseases were each associated with statistically significant decreases in COHb (p < 0.01). Increasing age was associated with decreased COHb levels at 2.8% per 10 years of life (p < 0.01), even when modeled with hypertensive and atherosclerotic disease. These findings carry important public health significance, as well as practical significance for the medical examiner when interpreting COHb levels in cases of suspected deaths due to smoke and soot inhalation. 相似文献

Peer crowds serve as an identity marker for adolescents, indicating their image and status among peers; but adolescents do
not always endorse peer appraisals of crowd affiliation. We report on two studies—one with 924 adolescents in grades 7–12
and a second with a more diverse population of 2,728 students in grades 9–11, followed for 2 years—that examined how congruence
between peer and self-appraisals of crowd affiliation relate to self-esteem and internalizing symptoms. Analyses indicate
that high-status crowd members may suffer and low-status crowd members benefit by denying their peer crowd affiliation, but
effects are modest in size and not entirely consistent across the two studies. Findings underscore the value of symbolic interactionist
principles concerning reflected appraisal processes in understanding how peer crowd affiliation affects adolescent self-image.

We examine the behavior of not-for-profits using utility maximization. This leads to testable hypotheses regarding the costs of agency associated with the activities of not-for-profits. Our tests are similar to those previously employed regarding not-for-profit objectives, but our interpretation is different. Our empirical test uses data on environmental groups. Unlike previous studies biased toward a finding of service maximization, we account for endogenous explanatory variables. A weak statement of our results is that managers of environmental groups derive positive marginal utility from expenditures for purposes other than providing services. There may also be empirical support for a stronger conclusion. 相似文献

The discovery in 1934 of the badly burned, pyjama clad body of a young woman protruding from a roadside culvert near Albury, N.S.W., led to one of the largest investigations in the history of Australian crime. Two simple errors, made by a local dentist with no previous experience in forensic odontology called by the police to examine the teeth of the victim, resulted in a delay in identification for 10 years. This paper examines the background of the odontological evidence which ultimately led to the identification of the victim and the conviction of the offender. 相似文献
