Facilities and HIV prevention in bathhouse and sex club environments

This project evaluated the extent to which businesses with a primary purpose of providing opportunities for sexual encounters between men (e.g., bathhouses and sex clubs) have implemented strategies that target their customers with important HIV and STD prevention messages. Between October 1996 and February 1997, we conducted structured telephone interviews with 63 businesses throughout the United States in order to describe their facilities and their HIV education and prevention efforts. Types of facilities offered were related to what businesses called themselves and the kinds of sex space they provided. All of the businesses reported that they provided condoms and lubricant on site; 95% provided educational materials such as posters and flyers about HIV/AIDS; and 40% provided HIV testing on site, with half of these also providing some type of STD testing. Although some level of HIV prevention and educational efforts by these businesses are described, further investigation into their efficacy is required.     

Testing an Economic Model of Nonprofit Growth: Analyzing the Behaviors and Decisions of Nonprofit Organizations,Private Donors,and Governments

This study draws an economic model of the growth of nonprofit organizations by analyzing the behaviors of three major actors—nonprofit organizations, private donors, and governments—in making decisions on the allocation of limited resources for nonprofit services. Since decisions made by each actor affect resource allocation, it is important to understand what drives these decisions. The model was tested using an unbalanced, 463 panel dataset collected from 28 OECD countries over a 23-year period. The results indicated that macro- and micro-economic trends and government policies framed the decision premises of the three major actors, which led them to leverage the supply and demand for goods and services and, in turn, determined how they allocated limited resources for nonprofit services. This result implies that understanding the interdependencies of all sectors of the economy is critical to comprehending the size and development of the nonprofit sector. Effective management of micro-economic policies and macro-economic stability is necessary. More important, however, is understanding how a decision in one part of the economy will have intended and unintended effects on the nonprofit sector.     

Impact of the National Minimum Wage on Disabled People

The survey reported here found disparities in the impact of the introduction of the National Minimum Wage on disabled people. These were associated with age, gender, impairment and type of employment setting. The main determinant of whether individuals gained from the NMW was their status as claimants of welfare benefits. We also found evidence that paid hours had been reduced to implement the NMW with no net increase in earnings, possibly to enable people to retain benefits entitlements. We make recommendations about how the anomalies can be tackled. It may be unrealistic to expect the Act to have been implemented fully so soon after it became law and some of the anomalies found may eventually disappear. However, many of the inequalities uncovered by this survey are not addressed by the NMW, specifically those inequalities associated with impairment and gender.     

A Semiparametric Regression Model for Longitudinal Data with Non‐stationary Errors

Motivated by the need to analyze the National Longitudinal Surveys data, we propose a new semiparametric longitudinal mean‐covariance model in which the effects on dependent variable of some explanatory variables are linear and others are non‐linear, while the within‐subject correlations are modelled by a non‐stationary autoregressive error structure. We develop an estimation machinery based on least squares technique by approximating non‐parametric functions via B‐spline expansions and establish the asymptotic normality of parametric estimators as well as the rate of convergence for the non‐parametric estimators. We further advocate a new model selection strategy in the varying‐coefficient model framework, for distinguishing whether a component is significant and subsequently whether it is linear or non‐linear. Besides, the proposed method can also be employed for identifying the true order of lagged terms consistently. Monte Carlo studies are conducted to examine the finite sample performance of our approach, and an application of real data is also illustrated.     

Simultaneous confidence band for the difference of segmented linear models

Consider comparing between two treatments a response variable, whose expectation depends on the value of a continuous covariate in some nonlinear fashion. We fit separate segmented linear models to each treatment to approximate the nonlinear relationship. For this setting, we provide a simultaneous confidence band for the difference between treatments of the expected value functions. The treatments are said to differ significantly on intervals of the covariate where the simultaneous confidence band does not contain zero. We consider segmented linear models where the locations of the changepoints are both known and unknown. The band is obtained from asymptotic results.     

试论人文管理在高校教学管理中的应用

人文管理理论目前广泛应用于企业管理之中。人文管理不仅以人为中心,而且要以德育人,以科学、文化武装人,以伦理道德、文化修养调剂人际关系,培养人的灵魂,提高人的素质,挖掘人的潜力,目标是促进人的全面自由发展。实行人文管理应遵循的基本原则是:应顾及到民族的文化传统的信念。人文管理适合于教学管理。在高等教育大众化背景下,人文管理通过良好文化氛围的营造,以文化影响人,以文化管理人,推动高校教学管理开创新的局面。

Proportional Trapping-Removal Model with a Known Ratio

ABSTRACT

Population size estimator is derived for a proportional trapping-removal model with a known ratio between two sub-population sizes, and the corresponding asymptotic properties is obtained. The performance of the proposed estimator is checked via simulation studies and an example.
