试论鲁迅的文化性格及其越文化印痕

新世纪的鲁迅研究应该进一步"回到鲁迅那儿去",要重视鲁迅自身,重视鲁迅身上最恒定的,最富于个性色彩的,明显的与他人有别的带有基本特征的东西,如鲁迅的文化性格和鲁迅身上的越文化印痕就是值得我们关注的两个问题.鲁迅之为鲁迅,是由于他有特殊的文化性格,即独立自由的现代人格精神,这种文化性格不仅仅在殖民地半殖民地时代,而且在这之后仍然是中国人民最可宝贵的性格.形成鲁迅宝贵的文化性格的原因是多方面的,其中我们可以发现越文化深层的印痕.     

Evaluation of a tobacco prevention program on knowledge, attitudes, intention and behavior of tobacco use among fourth grade students--a preliminary study

This was a preliminary study to evaluate the effectiveness of a tobacco prevention program on knowledge, attitude, intention, and behavior of tobacco use among fourth-grade students in four north central Florida counties. The results suggest that the program was effective in improving students' knowledge, attitudes, and intention toward not using tobacco products. Data analysis showed that students in the education group had a greater improvement in knowledge than the comparison group. Students in the education group also improved their attitude and intention scores while the comparison group did not show any improvement. The results also indicated positive responses from the students. In addition, teachers also gave a very positive response to the program.     

Role of workplace safety: a revisit of the relationship between job satisfaction and employment status

This study evaluated the relationship between employment status (i.e., part- and full-time) and job satisfaction, with the focus on the moderating roles of perceived injury risk and injury incidence. The results found that the level of job satisfaction for full-time workers was about the same regardless of the level of injury risk they perceived. In contrast, job satisfaction of part-time workers was significantly higher when they perceived low injury risk rather than high injury risk. The findings also supported the potential adverse impact of injury incidence and injury risk on job satisfaction for both part- and full-time workers. This study highlighted the importance of understanding both workplace safety and job satisfaction when attempting to understand the differences between part-time and full-time workers.     

Marginal Regression of Gaps Between Recurrent Events

Recurrent event data typically exhibit the phenomenon of intra-individual correlation, owing to not only observed covariates but also random effects. In many applications, the population may be reasonably postulated as a heterogeneous mixture of individual renewal processes, and the inference of interest is the effect of individual-level covariates. In this article, we suggest and investigate a marginal proportional hazards model for gaps between recurrent events. A connection is established between observed gap times and clustered survival data with informative cluster size. We subsequently construct a novel and general inference procedure for the latter, based on a functional formulation of standard Cox regression. Large-sample theory is established for the proposed estimators. Numerical studies demonstrate that the procedure performs well with practical sample sizes. Application to the well-known bladder tumor data is given as an illustration.

Assessing the impact of new technology in information systems

Computer and communication technology is changing at an increasing rate. New technologies are emerging: the price- performance of current technology is improving. There is a need to assess the impact of technology on new information systems projects, particularly those dealing with distributed processing and electronic office systems. Such an assessment provides direction and guidance in long range and intermediate term information services planning. It can potentially prevent costly conversion efforts. An approach is developed for obtaining this assessment. Two case examples of applications are provided which illustrated the method, results and benefits.
