A Tale of Two “Unorganizables”

How should we define “organizability?” I identify here four factors that contribute to a group’s organizability: organizers’ expectations, labor market structures, employers’ actions, and workers’ union sentiments. I briefly discuss how the first three factors correspond with workers’ union sentiments in comparing two divergent occupations: teaching assistants (TAs) and web designers. Workers must choose between conflicting identities in constructing themselves as “organizable” workers. While TAs ultimately framed their identities primarily as employees, web designers still consider themselves unorganizable. I explore similarities and differences between these cases and propose some steps union organizers and web designers could take in unionizing.

基于Peti网的WEB服务组合建模及验证

Web服务组合是为了应对日益复杂的业务处理流程,将单一的web服务组合在一起形成一个新的服务。正确的组合web服务是有效应用这些服务的前提,为此研究了利用Petri网组合Web服务的方法和web服务组合模型的验证算法。在对工作流和Web服务组合进行分析对比的基础上,借鉴基于Petri网的工作流建模技术,给出了一种基于Petri网技术的Web服务组合建模方法．采用直观的图形表示Web服务组合模型。结合Web服务组合模型的合理性定义,设计出Web服务组合模型合理性验证算法,利用库所向量和服务集合的表示方法对Web服务组合模型进行分析验证。最后用一个具体实例对Web服务组合建模和验证方法作进一步说明。     

Sociodemographic and Health-Related Risk Factors Among African-American,Caucasian and Hispanic Homeless Men: A Comparative Study

Data from a 1989-1990 cross-sectional survey of homeless adults in California were stratified by ethnicity to examine whether adverse childhood events and adult medical disorders preceding homelessness differed between 269 African-American, 599 Caucasian, 201 foreign-born Hispanic, and 136 native-born Hispanic men. Although African-Americans were overrepresented (21%) compared with their presence in local (3%) and state (7%) populations, within the homeless they were better educated and more likely to have held white collar jobs than Caucasians or Hispanics. In addition, despite being more likely to grow up in poverty, African-Americans reporled lower prevalences of alcohol and drug abuse, overnight psychiatric hospitalizations, placement in foster care, and physical or sexual abuse than Caucasians. Foreign-born Hispanics were the most likely to have low levels of education and job skills, but were least impaired by adult medical disorders. Native-born Hispanics reported lower rates of adverse childhood events, illegal drug use, and psychiatric hospitalizations than Caucasians, but were most likely among the three ethnic groups to suffer from alcohol abuse. The lower prevalences of adverse childhood events, addictive disorders, and psychiatric hospitalizations among homeless African-Americans, despite their higher representation in absolute numbers, suggests that factors such as childhood poverty may play a disproportionate role in homelessness among this ethnic minority group.     

一种基于QoS综合匹配的Web服务选择方法

当前基于QoS的Web服务选择方法,缺乏同时考虑QoS语义和数值处理及用户的个性化需求。基于多属性理论,提出一种QoS综合匹配方法用于筛选功能相同但QoS属性不同的候选Web服务。本方法包含QoS语义和数值综合匹配、构建多属性决策矩阵、个性化服务选择这几个阶段。实验验证本方法推荐结果符合用户需求。     

Computer Technology Utilization and Community-Based AIDS Organizations

SUMMARY

This study explores the computer utilization patterns of 107 community-based AIDS organizations in Canada. A questionnaire examined the current hardware/software capacities of agencies, knowledge and use of the Internet and its capabilities as a tool for psychosocial support, and barriers to computerized service provision. It also explored consumers' utilization and knowledge of computer-mediated technologies, and barriers to service. Results suggest agencies have resource-related dilemmas, relating to limited finances, time and personnel capacities. Consumers are challenged by a lack of access to computers, limited awareness of computer-mediated technologies, and other inhibiting factors. Future directions for community-based AIDS organizations are considered.     

Improving response to an establishment survey through the use of web-push data collection methods

ABSTRACT

The web-push method has been shown to increase web response rates in general public surveys. Response rates from two waves of the Emergency Medical Services for Children Program’s Performance Measures Survey, a state-administered establishment survey, were compared to determine if the second wave's revised, centralized implementation strategy improved response rates and consistency across states. The centralized strategy included the web-push design; a carefully timed contacts; and a three-month timeline. The results of the centralized web-push method included a higher overall response rate for a three-month period (81.0% compared to 56.6%) as well as greater consistency in results across states.
