Community-Based Participatory Research is a research paradigm that encourages community participation in designing and implementing evaluation research, though the actual outcome measures usually reflect the “external” academic researchers’ view of program effect and the policy-makers’ needs for decision-making. This paper describes a replicable process by which existing standardized psychometric scales commonly used in youth-related intervention programs were modified to measure indicators of program success defined by community partners. This study utilizes a secondary analysis of data gathered in the context of a community-based youth violence prevention program. Data were retooled into new measures developed using items from the Alabama Parenting Questionnaire, the Hare Area Specific Self-Esteem Scale, and the Youth Asset Survey. These measures evaluated two community-defined outcome indicators, “More Parental Involvement” and “Showing Kids Love.” Results showed that existing scale items can be re-organized to create measures of community-defined outcomes that are psychometrically reliable and valid. Results also show that the community definitions of parent or parenting caregivers exemplified by the two indicators are similar to how these constructs have been defined in previous research, but they are not synonymous. There are nuanced differences that are important and worthy of better understanding, in part through better measurement. 相似文献

I seem to know that I won't experience spaceflight but also that if I win the lottery, then I will take a flight into space. Suppose I competently deduce from these propositions that I won't win the lottery. Competent deduction from known premises seems to yield knowledge of the deduced conclusion. So it seems that I know that I won't win the lottery; but it also seems clear that I don't know this, despite the minuscule probability of my winning (if I have a lottery ticket). So we have a puzzle. It seems to generalize, for analogues of the lottery-proposition threaten almost all ordinary knowledge attributions. For example, my apparent knowledge that my bike is parked outside seems threatened by the possibility that it's been stolen since I parked it, a proposition with a low but non-zero probability; and it seems that I don't know this proposition to be false. Familiar solutions to this family of puzzles incur unacceptable costs—either by rejecting deductive closure for knowledge, or by yielding untenable consequences for ordinary attributions of knowledge or of ignorance. After canvassing and criticizing these solutions, I offer a new solution free of these costs. Knowledge that p requires an explanatory link between the fact that p and the belief that p. This necessary but insufficient condition on knowledge distinguishes actual lottery cases from typical, apparently analogous ‘quasi-lottery’ cases. It does yield scepticism about my not winning the lottery and not experiencing spaceflight, but the scepticism doesn't generalize to quasi-lottery cases such as that involving my bike. 相似文献

The purpose of the present paper was to test the effectiveness of the r-cards in sport performance, and to examine what kind of benefits and challenges the head coach, team manager and female basketball players (N = 12) faced when using the r-cards. Mixed methods were employed to gather specific data to answer the research questions. Inferential statistical analyses were conducted to examine whether players’ performances in terms of their targeted defensive rebound percentage and free-throw percentage differed across the five matches played. No significant differences were found. However, evidence from the qualitative data provides a contrasting but insightful perspective. Subjectively, the r-cards strategy was seen as beneficial because it improved the team’s performance and preparations, helped the players in goal setting, identification of weaknesses, and recognition of effort. In contrast, realistic goal setting, irrelevance of some reflection questions, effort recognition, and feedback to head coach were found challenging in r-cards usage. The paper closes with a critical discussion on the implications for future use of r-cards in the field of sport coaching. 相似文献

In eye movements, saccade trajectory deviation has often been used as a physiological operationalization of visual attention, distraction, or the visual system’s prioritization of different sources of information. However, there are many ways to measure saccade trajectories and to quantify their deviation. This may lead to noncomparable results and poses the problem of choosing a method that will maximize statistical power. Using data from existing studies and from our own experiments, we used principal components analysis to carry out a systematic quantification of the relationships among eight different measures of saccade trajectory deviation and their power to detect the effects of experimental manipulations, as measured by standardized effect size. We concluded that (1) the saccade deviation measure is a good default measure of saccade trajectory deviation, because it is somewhat correlated with all other measures and shows relatively high effect sizes for two well-known experimental effects; (2) more generally, measures made relative to the position of the saccade target are more powerful; and (3) measures of deviation based on the early part of the saccade are made more stable when they are based on data from an eyetracker with a high sampling rate. Our recommendations may be of use to future eye movement researchers seeking to optimize the designs of their studies. 相似文献

Sexual coercion refers to strategies that result in an individual engaging in sexual activity against his or her will. Ecological factors influence the way sexual interactions occur; however, the relationship between these factors and sexual coercion has not been explored among university students in Ghana. The purpose of this study was to examine sexual coercion among university students in Ghana by specifically examining individual-level factors (age, gender, sexual debut, age differential with first partner, being in an intimate relationship, history of abortion, and past experiences with transactional sex) and the experience of forced and coerced sex. Residential students at the University of Cape Coast were invited to participate and completed a survey on a tablet computer. Questions included demographics; sexual and reproductive health experiences and knowledge; and attitudes and experiences with abortion. Bivariate and multivariate analyses were used to examine individual-level factors associated with experiences of sexual coercion and forced sex. There were 480 females and 556 males that completed the survey; 26.3 and 16.4% reported having had intercourse either because they were forced or coerced, or when they were “very unwilling”. These students were more likely to be female (OR 3.5), to have had an abortion (OR 2.9), and to have engaged in transactional sex (OR 1.9). Many University of Cape Coast students are experiencing forced or coerced sex. Programs targeting both female and male students as both victims and perpetrators of sexual violence in this population are sorely needed. Primary prevention of sexual violence is one promising field. 相似文献

The present study relies on symbolic politics theory to predict public attitudes toward the federal regulation of conventional tobacco products (a familiar attitude object) and reduced‐exposure tobacco products (a relatively novel attitude object). We predicted that attitudes toward most forms of regulation would be more strongly influenced by symbolic beliefs about the role of government in society than by self‐interested concerns, with the exception of taxation. We predicted that the financial consequences of taxation policies would be less ambiguous for those who are affected, resulting in a stronger relationship between self‐interest and policy attitudes. The results strongly supported our hypotheses, suggesting a process by which symbolic beliefs and self‐interested concerns influence attitude formation. Theoretical and policy implications are discussed. 相似文献

The aim of this study was to examine whether memorizing advertised products of television advertisements with magical effects (i.e., talking animals, inanimate objects which turn into humans, objects that appear from thin air or instantly turn into other objects) is easier than memorizing products of advertisements without such effects, by testing immediate and delayed retention. Adolescents and adults viewed two films containing television advertisements and were asked to recall and recognize the films' characters, events, and advertised products. Film 1 included magical effects, but Film 2 did not. On a free-recall test, no differences in the number of items recalled were noted for the two films. On the immediate recognition test, adolescents, but not adults, showed significantly better recognition for the magical than the nonmagical film. When this test was repeated two weeks later, results were reversed: adults, but not adolescents, recognized a significantly larger number of items from the magical film than the nonmagical one. These results are interpreted to accentuate the role of magical thinking in cognitive processes. 相似文献

This study examines the time course and neural generators of oscillatory beta and gamma motor responses in typically-developing children. Participants completed a unilateral flexion–extension task using each index finger as whole-head magnetoencephalography (MEG) data were acquired. These MEG data were imaged in the frequency-domain using spatial filtering and the resulting event-related synchronizations and desynchronizations (ERS/ERD) were subjected to voxel-wise statistical analyses to illuminate time–frequency specific activation patterns. Consistent with adult data, these children exhibited a pre-movement ERD that was strongest over the contralateral post-central gyrus, and a post-movement ERS response with the most prominent peak being in the contralateral precentral gyrus near premotor cortices. We also observed a high-frequency (∼80 Hz) ERS response that coincided with movement onset and was centered on the contralateral precentral gyrus, slightly superior and posterior to the beta ERS. In addition to pre- and post-central gyri activations, these children exhibited beta and gamma activity in supplementary motor areas (SMA) before and during movement, and beta activation in cerebellar cortices before and after movement. We believe the gamma synchronization may be an excellent candidate signal of basic cortical motor control, as the spatiotemporal dynamics indicate the primary motor cortex generates this response (and not the beta oscillations) which is closely yoked to the initial muscle activation. Lastly, these data suggest several additional neural regions including the SMA and cerebellum are involved in basic movements during development. 相似文献

Abstract: Two common ways of explaining akrasia will be presented, one which focuses on strength of desire and the other which focuses on action issuing from practical judgment. Though each is intuitive in a certain way, they both fail as explanations of the most interesting cases of akrasia. Spinoza's own thoughts on bondage and the affects follow, from which a Spinozist explanation of akrasia is constructed. This account is based in Spinoza's mechanistic psychology of cognitive affects. Because Spinoza's account explains action asissuing from modes of mind that are both cognitive and affective, it captures the intuitions that motivate the two traditional views while avoiding the pitfalls that result from their one-sided approaches. This project will allow us a fuller understanding of Spinozist moral psychology. In addition to this historical value, the Spinozist theory may offer a satisfactory explanation of certain hard cases of akrasia while avoiding the problems be set by other theories. For this reason, the Spinozist account could also be seen as a useful contribution to our philosophical understanding of the phenomenon of akrasia. 相似文献
