Distinguishing Absentee Students from Regular Attenders: The Combined Influence of Personal,Family, and School Factors 总被引:1,自引:0,他引:1
Corville-Smith Jane Ryan Bruce A. Adams Gerald R. Dalicandro Tom 《Journal of youth and adolescence》1998,27(5):629-640
In the present study, the relationship between student attendance and personal characteristics of the student, the student's family relations, and school variables were examined in a sample of 54 high school students. Consistent with earlier reports, t-tests revealed statistically significant relationships between school absence and many student, family, and school variables. The data were also analyzed using a stepwise discriminant analysis. The results showed that the absentee and regular attending students could be distinguished based on a combined set of 6 variables representing each of the three domains of student, family, and school characteristics. The results further revealed that several variables that were statistically significant in the univariate analyses failed to be retained in the discriminant analysis, suggesting that these variables did not contribute sufficient unique variance to warrant their inclusion in the discriminant function. The implications of school absence as a multifactored problem is discussed with respect to assessment and treatment effectiveness. 相似文献

We fielded an experiment in the 2012 Cooperative Congressional Election Study testing the theory that motivated reasoning governs reactions to news about misdeeds on the campaign trail. Treated subjects either encountered a fabricated news story involving phone calls with deceptive information about polling times or one involving disappearing yard signs (the offending party was varied at random). Control subjects received no treatment. We then inquired about how the treated subjects felt about dirty tricks in political campaigns and about all subjects’ trust in government. We find that partisans process information about dirty campaign tricks in a motivated way, expressing exceptional concern when the perpetrators are political opponents. However, there is almost no evidence that partisans’ evaluations of dirty political tricks in turn color other political attitudes, such as political trust. 相似文献

AbstractLocation affordability measures a household’s combined cost of housing and transportation. Low-income households have the most to gain from housing with lower transportation costs. This research analyzes whether Housing Choice Voucher Program households—participants in a program designed to provide low-income households with a greater degree of housing choice—are able to choose housing that lowers their transportation costs in a metropolitan region with a compact, vital urban core. A mixed-methods approach is used to investigate the differences in location affordability and efficiency among 2,026 voucher recipients who moved within the Portland, Oregon, region during 2012–2013. Location mattered to movers, but in some unexpected ways. Urban movers relocated to less location efficient areas, whereas suburban movers’ location efficiency remained stable. In tight housing markets, voucher holders may be edged out of location-efficient neighborhoods and thus incur increased transportation costs. 相似文献

Objectives
Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect on recorded incidents of police use of force. In some sites, rates of use of force decreased and in others increased. We wanted to understand these counter-intuitive findings and report pre-specified subgroup analyses related to officers’ discretion on activating the BWCs.Methods
Using pre-established criteria for experimental protocol breakdown in terms of treatment integrity, ten experimental sites were subgrouped into “high-compliance” (no officer discretion applied to when and where BWCs should be used; n?=?3), “no-compliance” (treatment integrity failure in both treatment and control conditions; n?=?4), and tests where officers applied discretion during treatment group but followed protocol in control conditions only (n?=?4).Results
When officers complied with the experimental protocol and did not use discretion, use of force rates were 37 % lower [SMD?=?(?.346); SE?= .137; 95?% CI (?.614) – (?.077)]; when officers did not comply with treatment protocol (i.e., officers chose when to turn cameras on/off), use of force rates were 71 % higher [SMD?= .392; SE?= .130; 95?% CI (.136) – (.647)], compared to control conditions. When full discretion (i.e., overall breakdown of protocol) was applied to both treatment and control conditions, null effects were registered [SMD?= .009; SE=.070; 95?% CI (?.127) – (.146)], compared to control conditions.Conclusions
BWCs can reduce police use of force when then officers’ discretion to turn cameras on or off is minimized—in terms of both case types as well as individual incidents. BWCs ought to be switched on and the recording announced to suspects at early stages of police–public interactions. Future BWCs tests should pay close attention to adherence to experimental protocols.398.
This article examines what states are doing to help Temporary Assistance to Needy Families (TANF) recipients move into the workforce and become self‐supporting. We first present documentation regarding many different state TANF policies aimed at encouraging work, including benefit structures, time limits, work requirements, sanctions, and work supports. We then discuss how effective these policies are at helping welfare recipients get jobs and increase their income, by reviewing research on each of these elements. We conclude that the TANF program has been effective in increasing employment and decreasing welfare caseloads and expenses, but that this has not resulted in overall income gains for welfare recipients in the long run. We also conclude that the most promising state programs have a strong employment focus combined with focused training and educational opportunities. In addition, we also find that sanctions appear to be harming those most in need of assistance, and therefore that such policies should be reevaluated and refocused. 相似文献

Traditionally, new technology has been slow to enter the paper industry, which turns over its capital stock in about 40 years. In this paper, we will examine some of the reasons for this long transition period and the implications of such a transition period for government policy. If the turnover time could be cut in half, the potential energy savings could be 4 quadrillion Btu (Quads) in 20 years. Examples of new technologies that will become prominent throughout the paper industry by the year 2000 include vapor recompression evaporation, oxygen bleaching, twin-wire forming and extended nip pressing. We present explicit projections of production shares (based on a computer model) for selected new technologies. New technology blends into an industry over a period of years. This paper examines some of the factors that accelerate or retard this transition in the capital-intensive (“heavy”) industries. For purposes of this article, our example is the paper industry, and so the examples of new innovations are drawn from pulp and paper-making processes. (Incidentally, we use the term “paper” throughout as a shorthand for SIC 26, Pulp, Paper and Paperboard.) The examination of paper-industry technology reported here is based to a great extent on a study of industrial energy use [1] conducted by the Office of Technology Assessment (OTA) for the U.S. Congress. The OTA study examined the four most energy-intensive American industries (paper, steel, chemicals and petroleum refining), to identify technologies to improve energy efficiency, to project industrial energy use in each industry between now and the end of the century, and to assess the impact of various policies on energy use and energy efficiency. The study found remarkable similarities between the four industries. One notable commonality is the attitude of management towards introduction of new technology. 相似文献
