北京市城区公交停靠与道路通行状态的互动研究

在对公交停靠站点分类的基础上,通过对工作日平峰、高峰时段北京市典型道路通行状态和公交停靠站进行实地观测,利用调查统计数据考察公交停靠与道路通行状态的相互作用。为特大型城市公交停靠站设置模式、公交线路规划以及缓解城市交通拥堵提供新的思路和对策。结果表明,交叉口附近设置公交停靠站、公交排队至机动车道、站点占用机动车道以及连续多站点占用机动车道降低道路通行速度;道路拥堵越严重,公交进出站时间越长,且港湾式停靠站公交进出站时间普遍长于直线式停靠站。     

我国公共交通场站建设模式研究

一、我国公共交通场站建设现状我国城市公共交通系统由公共交通工具、公共交通线网及公共交通场站等部分组成,其中公共交通场站是公共交通系统中最为重要的部分。在提升城市公共交通系统的服务水平的过程中,公共交通场站建设有着举足轻重的作用。笔者所提及的公共交通场站是指城市公共汽、电车场站,包括首末站、中途站、换乘枢纽、停车场及保养场等。公共交通场站不但在整个交通系统中发挥着重要作用,其建设布局也为城市服务提供了关键

中心城市建设综合交通系统的经验、启示与对策——以伦敦、广州为例

通过分析伦敦的交通规划、建设、运营与管理措施,发现我国中心城市的严重交通拥堵主要源于落后的城市交通规划理念,大量引入多层高架公路进入市中心而忽视轨道交通建设,对公交优先存在认识上的误区和执行不力;城市公共交通工具营运各自为政,缺乏有效的协调与接驳;运营的低效率和管理不当,由此造成了典型的“大城市病”。根据后现代主义城市建设思想,结合当前中心城市公共交通体系建设的现状,提出了广州市综合交通体系建设的12项具体措施。

International Financial Integration and Its Distinctions in Transition Economies

We discuss the main tendencies and forms of international financial integration in both developing and developed economies. Integration of financial markets is a topic of economic debates especially for developed and transition economies, particularly Armenia, because it is the most effective way of overcoming the main problems of financial-sector development of transition economies. But there are many problems on the way of financial integration, which are summarized into four groups: institutional problems, legislative problems, macroeconomic instability, and technical problems. All of these problems are analyzed in the article for Armenia, though they are quite relevant for most transition countries.

An investigation of cognitive style and alcohol/work-related problems among Naval personnel.

This study examines the relationship between cognitive style (i.e., information, normative, and diffuse orientation, and commitment) and alcohol/work-related problems. A random sample of Naval personnel (n = 2000) with less than two years of service toward their first enlistment was sent a questionnaire to assess cognitive style [1] and alcohol/work-related problems. A total of 899 respondents (45.0%) returned their questionnaires. Findings support prevention strategies that incorporate problem-solving, decision-making, and coping strategies, particularly among participants who employ diffuse problem-solving/coping strategies (lack of exploration and commitment, avoidance of problems). Correlations between cognitive style and alcohol/work-related problems are theoretically compatible. Diffuse orientation scores are positively related to both alcohol- and work-related problems, while norm and information orientation scores are negatively related to both measures. Collectively, cognitive style measures explain 11.4 percent of the variability in alcohol-related problems, and 14.0 percent of the variability in work-related problems.     

Heavy alcohol use compared to alcohol and marijuana use: do college students experience a difference in substance use problems?

This study examines the risk for alcohol and other drug (AOD) problems resulting from alcohol plus marijuana use compared to alcohol-only use. Data are from telephone interviews with 1113 randomly selected college students attending two large urban universities in the southwestern United States. Alcohol and marijuana users (dual users) were more likely to be younger and report a higher mean number of drinks per occasion and experiencing all AOD problems studied compared to alcohol-only users. Multivariate logistic regression analysis findings reveal the relationship between dual-substance use and increased risk for AOD problems remained after controlling for demographics and alcohol use behaviors. Such problems include greater odds of legal problems and riding with or being an intoxicated driver. College students using alcohol and marijuana are at much higher risk for AOD problems than are students who use alcohol only, even when heavy drinking is taken into account.     

Some characteristics of moral problems in evaluation practice

In order to understand better the nature of moral problems in evaluation, an actual incident from evaluation practice is examined. Based on the incident, six characteristics of moral problems are identified and briefly discussed. The types of research needed on moral aspects of evaluation practice are presented, and ways in which the evaluation profession can aid practitioners in dealing with moral problems are outlined.     

Adoption,personality disorder and parental guilt: Implications of genetic research for social work

Few adoptive parents are aware that serious behavioral and personality problems can occur in adopted children. When such problems are manifested, parents are often guilt-ridden, believing that they are to blame. Recent research suggests that the risks associated with adoption may be genetically linked. Social workers who counsel adoptive parents need to be aware of potential problems, explain possible risks to them, and use these research findings to positive effect.     

Mexican-American families: A psychoeducational approach for addressing chemical dependency and codependency

Chemical dependency and codependency are often referred to as family problems, and the ways in which families frame these problems may be influenced by their ethnic and cultural background. Increased efforts are being made to help families understand the problems that arise from alcohol and other drug abuse by utilizing approaches that take into consideration their unique cultural aspects. This article reviews some of the ways in which Mexican-American families, in particular, may view chemical dependency and codependency. More importantly, it describes the cultural adaptation of a psychoeducational program to help. Mexican-American parents, primarily mothers whose children are drug involved or who are considered to be at risk for drug use, better address these problems.     

CULTIVATING SOCIETY'S CIVIC INTELLIGENCE: PATTERNS FOR A NEW 'WORLD BRAIN'

In spite of remarkable advances in science and technology, humankind is beset with a number of serious problems. These are not just problems that 'won't go away'; they are problems that are worsening considerably. These problems include the growing gap between rich and poor, between those who have too much and those who have too little, as well as a broad range of environmental issues that may have major consequences but, at the same time, are little understood. This essay explores the idea of 'civic intelligence'. What projects, perspectives, policy and technology might humankind develop that would help us collectively address these problems? This essay discusses six aspects of 'civic intelligence' (orientation, organization, engagement, intelligence, products and projects, and resources) as well as ways to make cultivating our 'civic intelligence' a practical - non-utopian - enterprise.     

“What problems do you confront?” an approach to doing qualitative research

Social life is filled with problems — situations that are perceived and defined as problems by individuals as they interact with each other. As such, these problems are often of more concern to those individuals than are other matters. The sociologist can gain insight into the structure of social relations by focusing the investigation on those problems rather than directly on the underlying structure. That is, the discussion of the problems that those being studied see in their situation or setting is revealing of the structured relations in those settings. This approach to doing social research is illustrated by two of the author's studies — one a study of an emergency department, and the second a study of how commercial art galleries affect the production and consumption of art.     

Sex differences in psychosocial consequences of alcohol and drug abuse

This paper reports analyses of the 1985 National Household Survey on Drug Abuse to evaluate three perspectives on sex differences in the relationship of psychosocial problems to levels of substance use. The results are more consistent with a styles of deviance perspective than with either the generalized feminine vulnerability or the convergence theses. Compared to women, men report higher levels of alcohol and drug abuse during the past year and are more likely than women to have experienced each of 17 psychosocial problems resulting from alcohol or drug use. Significant sex by substance use interaction tests for problem indices and for individual problems suggest that substance abuse is related more strongly to intrapsychic problems among women and to problems in social functioning among men. Decompositions of the sex differences in mean levels of psychological and social/behavioral problems suggest that most of the differences can be explained by males' greater frequency of intoxication and drug use.
