The present study was aimed at investigating whether different personality profiles could be found among Italian police Special Force (SF) officers. Our hypothesis was that different personality profiles would be found, and that they would differ with respect to psychological and organizational functioning. This conjecture was tested on anonymously collected Big Five scores of all members of a 'Reparto Mobile' unit (n?=?289) by means of a Two-Step cluster analysis. Two distinct personality profiles were found: two-thirds of participants showed a personality profile that was quite similar to the general population, with the exception of a higher self-reported emotional stability and self-deceptive enhancement, while the remaining third showed higher levels of any personality domain than both the other cluster and the general population. These officers also endorsed lower scores in measures of depression, anxiety, professional exhaustion, loss of empathy, and higher scores in a measure of organizational resilience, suggesting that they may represent the most suitable personnel for the delicate tasks their unit usually has to accomplish. In addition, self-deceptive enhancement emerged as a likely personality trait of police SF officers.  相似文献

This study focused on two-dimensional fast Fourier transform (2D-FFT) as a new technique for the discrimination of kraft tapes, which is a kind of adhesive packing tape. The 2D power spectrum (2D-PS) obtained by applying 2D-FFT to an image enables us to obtain information about the spatial periodicity, even if the periodicity is invisible within the image. However, in the case of kraft tape, peaks in the 2D-PS are too unclear to determine its periodicity. We developed novel analytical image processes combined with 2D-FFT. 2D-FFT was applied to 50 randomly selected areas in a transmitted light image of kraft tape. The 2D-PSs were calculated from each area without applying a logarithmic transformation, accumulated, and processed by the removal of the area surrounding the center, and finally normalized for visualization. These processes enhanced the peaks and eliminated local variations. Through an intra-roll comparison, the 2D-PSs collected from a roll were similar in the location of the peaks and in their patterns at low frequency area. Using an inter-roll comparison, the 2D-PSs from 50 commercially available brand-name products were classified into 26 groups based on these peaks and patterns. All results demonstrate that this method, which is convenient, rapid, and non-destructive, could be a valuable tool for the identification of kraft tapes.  相似文献

The rapid growth in the number of children participating in the Supplemental Security Income (SSI) program before the age of 18 has led policymakers to consider new methods of assisting children with disabilities in their transition from school to work. Postsecondary education represents one path that SSI children may take to acquire the skills necessary to enter employment and reduce dependency on the SSI disability program as adults. Yet little is known about SSI children's experience with postsecondary education, let alone their ability to increase their labor market earnings and reduce their time on SSI as adults in the long term. This lack of information on long-term outcomes is due in part to a lack of longitudinal data. This article uses a unique longitudinal data set to conduct a case study of SSI children who applied for postsecondary education at the National Technical Institute for the Deaf (NTID) within the Rochester Institute of Technology. The data set was created by merging NTID administrative data on the characteristics and experiences of its applicants to Social Security Administration (SSA) longitudinal data on earnings and program participation. We used this data file to estimate the likelihood that an SSI child will graduate from NTID relative to other hearing-impaired NTID applicants, and we estimated the influence of graduation from NTID on participation in the SSI adult program and later success in the labor market. The results of our analysis show that the percentage of NTID applicants who were SSI children increased over time, from a low of 10 percent in 1982 to more than 41 percent in 2000. However, the differences in the probability of graduation from NTID between deaf SSI children and deaf applicants who were not SSI children did not change accordingly. The probability of graduation for SSI children who applied to NTID was 13.5 percentage points lower than for those who were not SSI children. The estimated disparity indicates that targeting college retention programs toward SSI children may be an effective way to improve overall graduation rates. Our results also show that SSI children who graduated from NTID spent less time in the SSI adult program and had higher earnings than SSI children who did not gradu- ate. Compared with SSI children who were accepted to NTID but chose not to attend, SSI children who graduated from NTID left the SSI program 19 months earlier, were less likely to reenter the program, and at age 30 had increased their earnings by an estimated 49 percent. Our findings demonstrate that SSI children need not be relegated to a lifetime of SSI participation as adults, despite the poor overall labor market experience of this population since the creation of the SSI program in 1974.  相似文献

Boys engage in notably higher levels of resistance to schooling than girls. While scholars argue that peer processes contribute to this gender gap, this claim has not been tested with longitudinal quantitative data. This study fills this lacuna by examining the role of dynamic peer-selection and influence processes in the gender gap in resistance to schooling (i.e., arguing with teachers, skipping class, not putting effort into school, receiving punishments at school, and coming late to class) with two-wave panel data. We expect that, compared to girls, boys are more exposed and more responsive to peers who exhibit resistant behavior. We estimate hybrid models on 5448 students from 251 school classes in Sweden (14–15 years, 49% boys), and stochastic actor-based models (SIENA) on a subsample of these data (2480 students in 98 classes; 49% boys). We find that boys are more exposed to resistant friends than girls, and that adolescents are influenced by the resistant behavior of friends. These peer processes do not contribute to a widening of the gender gap in resistance to schooling, yet they contribute somewhat to the persistence of the initial gender gap. Boys are not more responsive to the resistant behavior of friends than girls. Instead, girls are influenced more by the resistant behavior of lower status friends than boys. This explains to some extent why boys increase their resistance to schooling more over time. All in all, peer-influence and selection processes seem to play a minor role in gender differences in resistance to schooling. These findings nuance under investigated claims that have been made in the literature.  相似文献

The treatment of youthful offenders in correctional settings presents psychologists with a range of challenging ethical concerns. The inherent discord between psychologically based goals and correctional objectives yields a complicated ethical landscape for clinicians. These concerns can be partially addressed through the APA's revised Ethical Principles of Psychologists and Code of Conduct (2010) and field-specific practice guidelines but also require extensive further guidance to ensure competent and ethical practice. This article analyzes current information about youthful offenders, outlines disparities in stakeholder goals, provides an overview of ethical considerations of treating youthful offenders in correctional settings, and offers recommendations for education and practice.  相似文献

Abstract

Congress gave the Resolution Trust Corporation (RTC) authority to sell modestly valued housing at below‐market prices and with concessionary financing to enable lower income families to become homeowners and to expedite sales. Nonprofits and public agencies seeking to buy properties for occupancy by lower income people also qualified for these favorable terms. Setting a precedent for future housing policy initiatives, Congress conditioned access to this special program on the imposition of permanent low‐income use and affordability restrictions.

This paper considers whether the RTC can reconcile its mandate to maximize preservation of affordable housing with its duty to maximize return on assets and minimize negative impacts on local markets. This issue is addressed through a comparative review of property disposition programs administered by three other federal agencies. The author concludes that the RTC's three goals can be harmonized and suggests criteria for evaluating the RTC's performance in meeting its affordable housing mandate.  相似文献
