Of the 39 states that permit some form of public sector collective bargaining, union security agreements are prohibited in 19. Employees may join and pay dues to the union representing them in these states but they are not required to do so. This study of 372 state government workers compares union dues-payers and non-dues-payers on a variety of personal, positional, economic, and noneconomic variables. Workers who were exposed to more physical danger and less noise were more likely to be dues-payers; higher seniority workers and skilled craftworkers were more likely to pay dues. Results suggest that union voting and union dues-paying have different antecedents. They also raise questions about the generalizability of previous dues-paying research to blue-collar settings. Holding a union card in a right-to-work environment seems to have little to do with the traditional collective pursuit of economic power.  相似文献

The California Agricultural Labor Relations Act (CALRA) evolved in the 1970s because the National Labor Relations Act (NLRA) excluded agricultural workers. CALRA effectively placed the United Farm Workers Union in a stronger bargaining position vis-a-vis farmers than the NLRA had done for industrial unions vis-a-vis nonfarm business firms. Society has suffered a net economic loss from CALRA and the events preceding its enactment. Since passage of the act, at least three effects have been verified: Relative to conditions that would otherwise have been expected to exist, consumers are facing higher prices; agricultural workers are earning lower wages; and landowners have suffered losses in land values.  相似文献

This article examines the relationship between President LyndonJohnson and those who take published polls. As his poll ratingsdeclined, Johnson used a number of methods to convince thosewith influence that he was more popular than the polls indicated.These methods included direct and indirect attacks on the polls,leaks of private polls, attempts to influence the results, andcourting the pollsters. The article argues that the last ofthese poses a danger to the objectivity of the pollsters. Secretlygiving advice to and taking private polls for a president areincompatible with the role of objective measurer of public opinion.  相似文献

The various costs of Type I and Type II errors of inference from data are discussed. Unfortunately, other things equal, Types I and II errors are inversely related. Six methods of minimizing Type I error in studies are presented, each of which may be employed even after data are collected. Type II errors may also be minimized by a combination of study design and analytic means. Although some of these techniques must be built into the study others can be undertaken when beginning work on a data set. Only one of these techniques will increase Type I error, and those involving data reduction may decrease both types of error.  相似文献

Two training procedures were compared with respect to the average number of training trials it took to teach new verbal responses to normal children. Mand contingencies were alternated with tact contingencies in one condition while only tact contingencies were in effect in the other condition. Normal, preschool children served as subjects and toy parts were the objects that were to be named. The results indicated that it took, on the average, fewer trials to teach part names (tacts) in the mand-tact condition than in the tact only condition. Although more research is needed to confirm this, it appears that mand contingencies involve stronger controlling variables and can facilitate the acquisition of a tact repertoire.

The Internet is seen by many as a form of cyberspace or environment in which to interact and socialise. This research project drew from the data of a quantitative and qualitative study of gay men in Perth, Western Australia. We examined gay men's usage patterns of chat rooms and other social aspects of the Internet to meet sexual partners. We then reviewed in detail the meanings gay men have for the various Internet environments, and the range of friendship, relationship, casual, or esoteric sex-seeking goals. We argue that gay men view and engage with the Internet differently from how they view and engage with other more traditional gay spaces. This different approach influences how interaction between the men, either online or face-to-face, progresses and how assumptions and expectations are built. This has implications for how sexual health promotion interventions determine the appropriate role and relationship they have with these online social spaces.  相似文献
