Information sharing research has largely focused on capturing operational practices related to the exchange of information. A noticeable shortcoming of this developing literature is the lack of scholarly attention focused specifically on analytic personnel. The present study employs semi-structured interviews with 23 personnel that comprise the analytic unit within a regional fusion center located in a large metropolitan area in the United States. Findings indicate that there is significant ambiguity surrounding the organizational and geographic audiences to which intelligence products should be tailored. Moreover, it appears information sharing is sparse and reliant upon personal relationships between analysts and external organizations. Lastly, analysts do not receive feedback pertaining to the content and effectiveness of intelligence products created. These findings may be generalized to other analytical organizations whose primary goal is to gather, analyze and disseminate intelligence. Action steps for policymakers are provided. 相似文献

This paper examines race-based peremptory challenges. Such challenges occur during the voir dire jury selection process. The process allows both the defense and the prosecution to strike jurors who they believe will not
decide cases fairly. However, in the case of Batson v. Kentucky 476 U.S. 79 (1986), the Supreme Court ruled that race could not be used as a factor in eliminating prospective jurors. This
paper examines federal litigation for five years in which it was alleged that race was used as a factor in removing a juror.
An examination of the cases revealed that most of the cases involved sole male litigants who allege that there were multiple
race-based peremptory challenges used in their cases. Moreover, most of the cases that led to the allegations involved violent
offenses. Other case characteristics are noted, but of most significance was the finding that most appellants lost their cases.
As such, the courts felt that most of the challenges were, in fact, race neutral. The implications of this research are discussed.

This study evaluated the use of different degree day (DD) models, developmental thresholds and developmental data sources for estimating postmortem interval (PMI) based on developmental rates of blow flies (Diptera: Calliphoridae). Blow fly evidence was collected from three mock crime scenes and sent for blind analysis of PMI. PMI estimates were calculated using averaging, single sine, double sine, single triangle, and double triangle models of DD calculation with minimum developmental thresholds of 0, 6 and 10 °C and Anderson's, Byrd and Allen's, Greenberg's, Nishida's and Kamal's developmental data sets. These estimates were compared with the actual PMI to determine which combination of DD model, developmental threshold and developmental data provided the most accurate estimate. For all three cases, at least one method gave a PMI estimation that was within 1 day of the actual date of death. There was no variability between PMI estimated using the five models of DD calculation. Overall, as lower developmental threshold increased, the PMI interval estimates increased. Depending on the developmental data set used, increasing the lower developmental threshold caused some overestimations of the date of oviposition, with estimates given that were prior to the actual death. Future PMI estimates should include error ranges, so that overestimation of PMI is avoided. 相似文献

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR® SGM Plus® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h. 相似文献

At least one‐quarter of covered workplaces violated the parental leave requirements of the Family and Medical Leave Act of 1993 (FMLA) when surveyed in 1997. What explains this noncompliance? Using a survey of 389 U.S. workplaces and qualitative interviews with managers in 40 organizations, I demonstrate that noncompliance comes in distinct forms. Some forms of noncompliance result from a failure to update institutionalized—and gendered—policies, practices, and norms. This form of noncompliance (indicated by illegally short leaves) is better explained by the institutional perspective, while outright noncompliance (as evidenced by a lack of leaves) is best explained by rational choice and deviant culture theories. 相似文献

When I first arrived here a few months ago, I couldn't help but notice several work projects going on all around me. A new dorm was being built on campus where I would be teach-ing, as well as a courtyard being repaved and bricked in front of the female students' dormitory, and a building next to my gym was being renovated. I wondered how long it would take to finish these large tasks, espe-cially the courtyard, as school would begin in about a week, and it would be a mess for students to have to walk through mud, over piles of sand, and around stacks of bricks to get where they wanted to go. 相似文献
