VC++中基于ODBC的数据库访问技术研究

ODBC是一个允许应用程序连接外部数据库服务器和文件、并执行查询操作的标准协议。应用程序只需要相同的ODBC源代码就可以访问不同的数据库管理系统。VC++提供了多种方法使用ODBC,比如ATL和MFC类库。对Windows2000环境下VisualC++6.0中MFC类库的ODBC数据库访问技术进行探讨。     

DURATION MODELS FOR CREDIT RATING MIGRATION: EVIDENCE FROM THE FINANCIAL CRISIS

We introduce a specific duration model to analyze the prediction of the credit rating migration. We consider hazard rate processes based on multi‐state autoregressive conditional duration models. To take account of the economic context, we model the conditional mean of the duration between two ratings by means of a latent process. To this purpose, a dynamic‐ordered probit model is developed to describe the directions taken by the ratings in the presence of multiple states. As an illustration, we study the migration of credit rating during periods before and after the financial crisis. (JEL C14, C41, G24)     

ACADEMIC PROBATION,STUDENT PERFORMANCE,AND STRATEGIC COURSE‐TAKING

We use a regression discontinuity design to study how academic probation affects outcomes and course‐taking behaviors at a large public university in the United States. Consistent with past work, students placed on probation improve their grade point average (GPA) in the subsequent semester. We document that part of this GPA improvement is attributable to strategic course‐taking, and there is significant heterogeneity in these behaviors across race. Non‐minority students placed on probation attempt fewer credits, easier courses, and are more likely to withdraw from courses in the following term. In contrast, underrepresented minorities exhibit few of these behaviors, consistent with past work that suggests black and Hispanic students are less likely to possess helpful institutional knowledge and use available support systems such as academic counseling.

Aesthetic matters: writing and Cultural Studies

What would it mean to treat Cultural Studies as a project that has had amongst its accomplishments the production of new forms and styles of writing, and a generative approach to aesthetics? An initial answer to this question would be that this would recognize how Cultural Studies interceded in an academic environment not only through its concern with supplying ambitious questions and insisting on a broad range of objects of scrutiny, but also by showing how this often entailed reconfiguring the forms through which intellectual inquiry conveyed its cargo. This article doesn’t seek to provide a taxonomy of Cultural Studies’ forms and styles; what it seeks to do is to encourage a self-reflexive attention to aesthetics within Cultural Studies as a form of practice. It suggests that there are two guiding questions that might frame such an attention: how might Cultural Studies generate forms that are adequate to the complexity of the configurations that it seeks to register; and how might Cultural Studies generate forms that could reach the ear of new audiences not attuned to the cadences of scholarly writing? The tension between these two questions should be seen as an invitation to purposeful experimentation within Cultural Studies.     

Immigration and violence: The offsetting effects of immigrant concentration on Latino violence

Despite longstanding interest in the effects of immigration on American society, there are few studies that examine the relationship between immigration and crime. Drawing from social disorganization theory and community resource/social capital perspectives, this study examines the effects of Latino immigration on Latino violence. Data on violence (i.e., homicide, robbery, and Violent Index) and the structural conditions of Latino populations are drawn from the California Arrest Data (CAL), New York State Arrest Data (NYSAD), and U.S. Census data for approximately 400 census places during the 1999–2001 period. Findings suggest that immigrant concentration has no direct effect on Latino homicide or Violent Index rates but may reduce Latino robbery. Immigration also appears to have multiple, offsetting indirect effects on Latino violence that work through social disorganization and community resource measures. These results suggest that (1) immigrant concentration does not contribute to Latino violence and may even reduce some forms of violence, (2) immigration simultaneously stabilizes and destabilizes structural conditions in Latino populations, and (3) it is useful to examine both the direct and indirect effects of immigration on crime.

Personal sacrifice and corporate cultures: career progression for disabled staff in higher education

Disabled people are under-represented in higher education (HE), especially in senior posts. This article reports research on the perspectives of career progression into leadership held by disabled staff in one post-1992 university. Findings indicated that some participants were already engaged in leadership or aspired to such roles, and reported positive experiences. However, participants also experienced barriers to progression, including a lack of awareness of equality and diversity among managers and colleagues, inadequate professional development opportunities and the competitive organisational culture of management that could impact on their health and work–life balance. We conclude that disabled staff in HE do not yet have equal opportunities for progression into leadership roles compared with their non-disabled peers. There is a need for realignment of the culture of leadership and management to make it more compatible with the full inclusion of disabled staff in HE such that their unique contributions are valued.
