Accountability in grant-making requires a valid, fair and transparent selection process. This study proposes a four-step framework for validating such a process: determine standards for qualified applicants, assess inter-reviewer reliability, assess factorial validity, and assess reliability. This framework is applied to the Corporation for National and Community Service’s 2013 RSVP grant-making process. The standards were close to the highest points of reliability. Inter-reviewer reliability was above 0.90, a common threshold for high-stakes measurement. After conducting confirmatory factor analysis, the final model merged two of the original five domains of selection criteria, resulting in four domains. The final model was found to have strict measurement invariance, high convergent validity, and measurement reliability between 0.88 and 0.93 for all domains. The results validate the 2013 review process and indicated that the scores exhibited high degrees of reliability, giving public assurance that the process was sufficiently objective and accurately reflected program priorities. 相似文献

The Bronte family produced three major authors of the Victorian period, only one of whom, Charlotte, lived to enjoy her fame. Since the beginning, this family has elicited controversy, myth and speculation. The authors attempt an analysis of the complex dynamics of the Brontes, including its constituent ‘family cultures’, parent‐child alliances, sibling bonds and rivalries, the traumatic effects of three early deaths, and the strong theme of secrecy and ‘protection’ in a family dominated by Branwell Bronte's instability and eventual alcoholism. The authors speculate on how this family might have presented for treatment, and invite readers to consider how they, as family therapists, might have responded. 相似文献

Stormwater ponds now comprise a significant portion of standing water in urban areas. These ponds act to sequester excess run-off and pollutants, such as road salt deicers. While these man-made ponds are not intended to serve as freshwater ecosystems, it is becoming clear that they do provide habitat for many organisms, but we know little of their ecosystem structure, function and interactions with pollutants. From April through June 2009, we surveyed 8 stormwater ponds in the Red Run Watershed, Baltimore County, Maryland, USA to describe patterns in aquatic food webs associated with a gradient in road salt inputs. Periphyton, phytoplankton and zooplankton samples were collected from each pond every 4–6 weeks. Specific conductance, a measure of chloride salt loading, among the 8 ponds varied widely throughout the survey, ranging from 99 μS cm−1 to 19,320 μS cm−1. Low (average = 404 +/− 82.6 (SE) μS cm−1) and medium (average = 1749 +/− 267 (SE) μS cm−1) conductance ponds had lower algal biomass and higher densities of zooplankton taxa relative to high (average = 7231 +/− 2143 (SE) μS cm−1) conductance ponds, which were largely devoid of all zooplankton through the end of May. The observed decline in zooplankton density along an increasing chloride gradient is consistent with experimental results of road deicer effects, suggesting algal resources are possibly freed from grazing pressure as zooplankton consumers are negatively impacted by road salt exposure. Our results highlight the potential for both direct and indirect effects of road deicers on freshwater communities. 相似文献

This study investigates infants’ discrimination abilities for familiar and unfamiliar regional English accents. Using a variation of the head‐turn preference procedure, 5‐month‐old infants demonstrated that they were able to distinguish between their own South‐West English accent and an unfamiliar Welsh English accent. However, this distinction was not seen when two unfamiliar accents (Welsh English and Scottish English) were presented to the infants, indicating they had not acquired the general ability to distinguish between regional varieties, but only the distinction between their home accent and unfamiliar regional variations. This ability was also confirmed with 7‐month‐olds, challenging recent claims that infants lose their sensitivity to dialects at around that age. Taken together, our results argue in favor of an early sensitivity to the intonation system of languages, and to the early learning of accent‐specific intonation and potentially segmental patterns. Implications for the development of accent normalization abilities are discussed. 相似文献

The courtship disorder hypothesis maintains that voyeurism, exhibitionism, toucheurism‐frotteurism, and the preferential rape pattern are expressions of the same disorder (courtship disorder). Earlier studies had shown that with the exception of the preferential rape pattern these paraphilias co‐occur to a reasonably high degree. The present study (1) demonstrated that the preferential rape pattern co‐occurs with the above reasonably well established expressions of courtship disorder to a higher degree than other main paraphilic activity patterns do and (2) supported the conjecture that in addition to an erotic preference for unfamiliarity of target person‐or‐object (noted by earlier authors), three other paraphilic target‐person or object preferences may be connected with courtship disorder, though they are not at all virtually obligatory as is erotic unfamiliarity. These are choosing children and adults alike as target persons of the paraphilic activities, non‐gender dysphoric transvestism, and fetishism. 相似文献

The prevalence of male same‐gender sexual behavior in Mexico City in relation to HIV transmission was studied. A household probability survey of 8,068 adult men was conducted in 1992–93 using the Mexican National Health Survey sampling frame. The response rate was 59%. Differences between respondents and nonrespondents indicated no evidence for significant bias. A random subsample of 1,116 individuals provided serum or saliva for HIV testing. An estimated 2.5% of men practiced same‐gender sex in their lifetime: 2.1% (95% CI: 1.7 ‐ 2.4%) reported bisexual behavior and 0.4% (95% CI: 0.3 ‐ 0.6%) reported exclusively homosexual behavior. Among bisexuals, 70% reported sex only with women in the previous year, 7% reported sex only with men, 13% reported sex with both, and 10% were sexually inactive. A condom was used by 46% in their last homosexual encounter. An estimated 0.1% of married men were homosexually active in the previous year. The HTV prevalence estimate was 0.2% in the sample. The rate was 4% among homosexual/bisexual men and 0.09% in heterosexual men (p < 0.0001). Estimates of homosexual behavior and HTV infection from this population‐based sample are lower than results from nonprobability studies. The low prevalence of condom use anticipates future growth of the epidemic in the homosexual population. Bisexual behavior appeared to be infrequent and transitory, particularly among married men. 相似文献

Numerical uncertainty ranges are often used to convey the precision of a forecast. In three studies, we examined how users perceive the distribution underlying numerical ranges and test specific hypotheses about the display characteristics that affect these perceptions. We discuss five primary conclusions from these studies: (1) substantial variation exists in how people perceive the distribution underlying numerical ranges; (2) distributional perceptions appear similar whether the uncertain variable is a probability or an outcome; (3) the variation in distributional perceptions is due in part to individual differences in numeracy, with more numerate individuals more likely to perceive the distribution as roughly normal; (4) the variation is also due in part to the presence versus absence of common cues used to convey the correct interpretation (e.g., including a best estimate increases perceptions that the distribution is roughly normal); and (5) simple graphical representations can decrease the variance in distributional perceptions. These results point toward significant opportunities to improve uncertainty communication in climate change and other domains. 相似文献

This paper reviews the literature on the emergence of industries and the theoretical and methodological approaches employed. The analysis reveals that industry emergence can be depicted as a three‐stage process. In the first, initial stage, a disruption to the existing industrial order triggers the second, the co‐evolutionary stage, which includes four sub‐processes related to developments in technology, markets, activity networks and industry identity. The convergence of these sub‐processes leads to the third stage, a growth stage and the birth of a new industry. While these three stages and the four sub‐processes are well covered in the literature, the authors find that there is a lack of understanding in terms of the transitions between the stages, the interactions and interdependencies between sub‐processes and moderating factors of industry emergence. Future research can bridge these gaps by exploring the different origins and initial conditions of industries, the processes and interactions in the earliest stages of industry emergence, and the role of facilitating and managing industry emergence. This implies a shift in the research focus from the industries that have emerged to the nascent processes of emergence. 相似文献

OBJECTIVE AND PARTICIPANTS: From 2002 to 2005, the authors tested an interactive, Web-based method to encourage college students at risk for suicide to seek treatment. METHODS: The authors invited students at 2 universities to complete an online questionnaire that screened for depression and other suicide risk factors. Respondents received a personalized assessment and were able to communicate anonymously with a clinical counselor online. At-risk students were urged to attend in-person evaluation and treatment. RESULTS: A total of 1,162 students (8% of those invited) completed the screening questionnaire; 981 (84.4%) were designated as at high or moderate risk. Among this group, 190 (19.4%) attended an in-person evaluation session with the counselor, and 132 (13.5%) entered treatment. Students who engaged in online dialogues with the counselor were 3 times more likely than were those who did not to come for evaluation and enter treatment. CONCLUSIONS: The method has considerable promise for encouraging previously untreated, at-risk college students to get help. 相似文献
