This paper uses a natural experiment to document the impact of social pressure on voting behavior. The main hypothesis is that social pressure creates incentives to vote for the purpose of being seen at the voting act. This incentive is particularly high in small and close‐knit communities. Empirically, I analyze the effect of postal voting on voter participation in Switzerland. Optional postal voting decreased the voting costs, but simultaneously removed the social pressure to vote. In spite of the large reduction in voting costs, the effect on aggregate turnout was small. However, voter participation was more negatively affected in the smaller communities. This lends support to the view that social incentives played a role for certain people's voting decisions. (JEL: H0, Z13) 相似文献

In preparation for an electronic mail (e-mail) and web-based health promotion intervention across multiple worksites, secure, regulatory-compliant, user-friendly e-mail and Internet applications were used to recruit potential participants across worksites, to enroll participants, and to collect baseline health assessment data. Specific hardware and software information technology environments were required of the 19 participating worksites. Sequential e-mails introduced the study and invited participation. Twenty-four percent of all employees (1106 of approximately 4600) provided consent. E-mail delivered a web link for the baseline study assessment, and reminder e-mails were sent to prompt completion. Of those who consented, 888 (80%) completed baseline health and behavior data surveys. An HTML-native web survey software was more stable across computing environments. Using e-mail and web assessment, this research recruited, enrolled, and collected data from more than 850 participants. Technical and operational challenges emerged at each step. Solutions and recommendations are discussed. Overall, this experience suggests that the use of e-mail and web software can facilitate recruitment, enrollment, and data acquisition through direct contact with study participants. This experience yields a series of lessons learned for using e-mail and the Internet to support multi-site trials. 相似文献

This article explored retention patterns, as well as factors that predicted these patterns, in the evaluation of a relationship-based substance abuse prevention intervention study that targeted inner-city African American youth. A total of 851 contacts were made to retain 82% (n = 104) of the baseline sample (N = 127) in the evaluation. Results from multinomial regression analyses indicated that participants who were retained in the evaluation were more likely to perceive alcohol, tobacco, and other drug use as less risky and were more likely to report higher levels of family supervision than were evaluation attrits. Those who were easy to retain reported lower family conflict and fewer family relocations during the past year than those who were difficult to retain. Implications of these findings for developing retention strategies, as well as future research, are discussed. 相似文献

Proportional hazards model(Cox, 1972) is reviewed for the case of grouped data with one continuously measured covariate. This leads to a logit-rank procedure for tied data which is reduced to the test proposed by O’Brien(1978) and studied by O’Quigley and Prentice(1991) in the absence of ties. The proposed test is then applied to a special ranking method in order to study non-monotonic associations. 相似文献

A number of robust methods for testing variability have been reported in previous literature. An examination of these procedures for a wide variety of populations confirms their general robustness. Shoemaker's improvement of the F test extends that test use to a realistic variety of population shapes. However, a combination of the Brown–Forsythe and O'Brien methods based on testing kurtosis is shown to be conservative for a wide range of sample sizes and population distributions. The composite test is also shown to be more powerful in most conditions than other conservative procedures. 相似文献

This article discusses how young mothers in London, a mid-size city in Canada, utilize a drop-in centre service while attending an alternative programme to acquire secondary school credits. The central arguments made here are informed by key concepts in the field of girlhood studies. With its attention to the interconnections between gender, age, and generation as well as other aspects of social identity, girlhood studies provides crucial insight into the lived experiences of young mothers who straddle the space between girlhood and adulthood. We interpret the experiences of the young mothers who participated in this study in light of shifting meanings and expectations of girls and girlhood in the neoliberal era. Drawing on the concept of the ideal neoliberal girl subject embodied in the ‘can do’ and ‘at risk’ girl, this paper highlights the tensions in accessing a drop-in centre, which functions as both a site of security and surveillance, for a group of young mothers receiving social services. The findings revealed how girls who are mothers struggle to live in the present to assert a legitimate maternal identity even as they are prepared for the future through neoliberal public policies and other disciplinary practices. 相似文献

The current study evaluated whether training intraverbal naming would be sufficient to establish visual-visual matching-to-sample (MTS) performances in college students. In the first experiment, we used a multiple-probe design across stimulus sets to assess whether six participants could match arbitrary visual stimuli (AB) after learning to tact their two experimentally defined classes (A’ and B’) and then intraverbally relate their names (i.e., “A’ goes with B’”). All participants matched the stimuli accurately after training, as well as emitted the trained intraverbals. In the second experiment, we used a multiple baseline design across four participants to assess whether the same training would produce bi-directional intraverbals in the form of “B’ goes with A’,” and MTS performance consistent with symmetry (BA). All participants responded accurately during matching and intraverbal tests. Across both experiments, participants stated the trained intraverbals while performing the matching task. Results showed that MTS performance can be established solely by verbal behavior training. 相似文献
