开放式公园使用情况调研--以人民公园为例

开放公园是城市重要的公共活动平台。本文通过实地调研典型开放式公园的使用情况,采用观察、问卷等形式进行数据收集,并分析数据,从而反思开放式公园是否真正的满足市民的需求,是否在设计上真正做到了公园开放思路的初衷。

What Difference Does a Civil Union Make? Changing Public Policies and the Experiences of Same-Sex Couples: Comment on Solomon, Rothblum, and Balsam (2004).

Comments on the article by Solomon, et al. (see record 2004-14778-001). When Vermont became the first state in the United States to legalize civil unions for same-sex couples, it marked an important milestone in lesbian and gay Americans' struggle for equal rights. Against this background, S. E. Solomon, E. D. Rothblum, and K. F. Balsam's (2004) study, the first to examine experiences of same-sex couples who have undertaken civil unions, is a significant effort. The study provides valuable data about these couples, yet much remains to be learned. Further study of the impact of changing legal landscapes on experiences of same-sex couples and their families has the potential to add significantly to knowledge about contemporary family lives.

Personality and risk for Alzheimer's disease in adults 72 years of age and older: A 6-year follow-up.

[Correction Notice: An erratum for this article was reported in Vol 26(2) of Psychology and Aging (see record 2011-05802-001). This article contains an error in the Discussion, under the Implications, Caveats, Future Directions heading. The third paragraph includes the sentences that should have been removed. The corrected paragraph appears in the correction.] We conducted secondary analyses to determine the relationship between longstanding personality traits and risk for Alzheimer's disease (AD) among 767 participants 72 years of age or older who were followed for more than 6 years. Personality was assessed with the NEO-FFI. We hypothesized that elevated Neuroticism, lower Openness, and lower Conscientiousness would be independently associated with risk of AD. Hypotheses were supported. The finding that AD risk is associated with elevated Neuroticism and lower Conscientiousness can be added to the accumulating literature documenting the pathogenic effects of these two traits. The link between lower Openness and AD risk is consistent with recent findings on cognitive activity and AD risk. Findings have implications for prevention research and for the conceptualization of the etiology of AD. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

全周期变时段“三公”调度发电计划优化模型

以年度合同进度为主要控制目标的"三公"调度是我国目前最为普遍的调度模式,常用的安全约束机组组合(security constrained unit commitment,SCUC)/安全约束经济调度(security constrained economic dispatch,SCED)模型不能满足"三公"调度计算周期要求,为此建立了考虑电网安全约束的全周期发电计划优化模型,并依据不同时段发电计划的需求差异,进一步建立了全周期变时段发电计划优化模型,该模型可根据时段长度自动选择各种约束。算例结果表明全周期变时段发电计划优化模型能够适应"三公"调度需要,计算性能能够满足大规模电网发电计划精细化管理需要。     

Postplacement relationships between birth mothers and their romantic partners.

Using a mixed-methods approach, the understudied population of birth mothers who placed their infants for adoption 12–20 years ago was explored in the context of their romantic relationships. In a semistructured interview, 104 birth mothers answered detailed questions about their romantic relationships and adoption-related experiences. All birth mothers had disclosed the adoption placement to their romantic partners, and most had done so early because they wanted to be truthful about their past. On average, the birth mothers were satisfied with their romantic relationships and almost half did not believe that the adoption had affected it. Regarding contact in the adoption, a majority of the birth mothers' romantic partners (63.5%) were not directly involved in contact with the adoptive family or adopted youth. Implications about how adoption is perceived and processed within intimate relationships are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Determinants of carbon dioxide emissions: Empirical evidence from 69 countries

This study investigates the determinants of carbon dioxide emissions (CO₂) for a global panel consisting of 69 countries using a dynamic panel data model. To make the panel data analysis more homogenous, we also investigate the determinants of CO₂ emissions for a number of sub-panels. These sub-panels are constructed based on the income level of countries. In this way, we end up with three income panels; namely, high income, middle income, and low income panels. The time component of our dataset is 1985–2005 inclusive. Our main findings are that trade openness, per capita GDP, and energy consumption, proxied by per capita electric power consumption and per capita total primary energy consumption, have positive effects on CO₂ emissions. Urbanisation is found to have a negative impact on CO₂ emissions in high income, middle income, and low income panels. For the global panel, only GDP per capita and per capita total primary energy consumption are found to be statistically significant determinants of CO₂ emission, while urbanisation, trade openness, and per capita electric power consumption have negative effects on the CO₂ emissions.     

基于学生个性的研究型大学实验室模式研究

本课题针对传统实验教学内容单一,学生能力培养受限以及沿用计划性教学模式,学生只能被动记性学习等问题,着眼学生可开发的学习研究能力,提出一种基于学生个性的开放式实验教学模式,有针对性地研究探索在研究型大学实验室教学环节中,如何科学培养学生独立和协同进行科学研究和创新的能力,并使学生由被动学习转变为主动学习。通过实验教学在时间、空间、设备等方面的全面开放以及学生个体差异,在保证完成实践基本要求的基础上,采用不同层次的实验教学,给学生足够的自主选择空间,以充分发挥每个学生的主观能动性、想象力和创造力。
