Previous postmortem microbiome studies have focused on characterizing taxa turnover during an undisturbed decomposition process. How coexisting conditions (e.g., frozen, buried, burned) affect the human microbiome at the time of discovery is less well understood. Microbiome data were collected from two pediatric cases at the Wayne County Medical Examiner in Michigan. The bodies were found frozen, hidden in a freezer for an extended time. Microbial communities were sampled from six external anatomic locations at three time points during the thawing process, prior to autopsy. The 16S rRNA V4 gene amplicon region was sequenced using high‐throughput sequencing (Illumina MiSeq). Microbial diversity increased, and there was a distinct shift in microbial community structure and abundance throughout the thawing process. Overall, these data demonstrate that the postmortem human microbiome changes during the thawing process, and have important forensic implications when bodies have been substantially altered, modified, and concealed after death. 相似文献

When members of Congress neglect the needs of their districts or vote contrary to the wishes of their constituents, their public approval suffers. Does the same hold true for representatives at the state level? Using experiments, I explore whether people dole out similar rewards and penalties to state legislators and members of Congress for their successes and shortfalls in representing constituents. I find that a similar model of political accountability travels from national politics to state politics. People value policy representation, casework, and attention to the district as much from state legislators as they do from members of Congress. 相似文献

Don't Sweat the Details! Enhancing Congressional Committee Expertise Through the Use of Detailees 下载免费PDF全文
In contrast to the dramatic growth in the size and influence of the executive branch over the past 40 years, congressional committee staffing levels are at an all‐time low. Faced with growing demands to produce legislation and to conduct oversight of executive branch policymaking, Congress can and does supplement its existing staff by borrowing personnel, known as detailees, from federal agencies. Using an original dataset of detailees from 1997 to 2015, we analyze the degree to which congressional committees rely on detailees to increase legislative capacity. We find that committees in the House and Senate use detailees in different ways to further both legislative and oversight initiatives. 相似文献

In recent years an increasing quantity of UK legislation has introduced blended or ‘hybridised’ procedures that blur the previously clear demarcation between civil and criminal legal processes, typically on the grounds of normatively-motivated political expediency. This paper provides a critical perspective on instances of procedural hybridisation in order to illustrate that, first, the reliance upon civil law measures to remedy criminal law infractions can raise human rights issues and, second, that such instrumental criminal justice strategies deliberately circumvent the enhanced procedural protections of the criminal law. By conceptualising the rule of law as a structural coupling between the political and legal systems, and due process rights as necessary and self-imposed limitations upon systemic operations, this paper employs a systems-theoretical approach to critique this balancing act between expediency and principle, and queries the circumstances under which legislation contravening the rule of law can be said to lack legitimacy. 相似文献

Abstract: Since the mid‐1980s, the traditional “bricks‐and‐mortar” approach to delivering a single service through face‐to‐face contacts in government offices has been improved by the creation of one‐stop walk‐in centres that provide multiple services of a related or unrelated nature, by telephone call centres that provide both personal service and interactive voice response, and by the rapid growth of service delivery through the Internet. The challenge for governments is to determine how best to join up services within and between departments, across levels of government, between governmental and non‐governmental service providers, and across channels. This article focuses on the delivery of government services by bringing them together in “clusters” and delivering them through more than one service channel. The article explains the concept of service clustering and provides a model of its major components; uses this model as a framework for describing innovative clustering initiatives in several countries; and examines the implications of service clustering for public administration, with particular reference to privacy and security issues. Sommaire: Depuis le milieu des années 1980, I'approche traditionnelle brique et mortier adoptée pour la prestation d'un service unique par le biais de contacts personnels dans les bureaux du gouvernement a connu une amelioration avec la mise en place des guichets uniques qui offrent de nombreux services de nature connexe ou non, de centres d'appels téléphoniques fournissant à la fois des services personnels et une réponse vocale interactive, et grâce au développement rapide de la prestation de services par Internet. Pour les gouvernements, le défi consiste à déterminer comment regrouper les services au sein d'un ministère et entre les ministères, entre les paliers de gouvernement, entre les foumisseurs de services gouvernementaux et non gouvernementaux, et entre les mécanismes de prestation. Le présent article se concentre sur la prestation des services gouvernementaux regroupés et fournis par l'intermédiaire de plusieurs mécanismes de prestation. Il explique le concept de regroupement des services et présente un modèle de ses principales composantes; il se sert de ce modèle comme cadre pour décrire les initiatives innovatrices en matière de regroupernent de services dans plusieurs pays; enfin, il examine les répercussions du regroupernent des services sur l'administration publique, en particulier du point de vue de la confidentialité et de la sécurité. 相似文献

This article investigates knowledge and perceptions of women’s empowerment from the perspective of female livestock keepers and elucidates linkages between women’s empowerment and household nutrition in relation to livestock. Eight focus groups with 62 female livestock keepers were conducted in Tanzania. Women’s empowerment in livestock was associated with improved household nutrition. Other opportunities for empowerment were identified that could contribute to women’s decision-making power. The article recommends that all development interventions in the livestock sector be gender sensitive and engage local men in conversations about gender inequities. It also discusses other pathways to increase women’s empowerment and household nutrition. 相似文献

Achievement, engagement, and students’ quality of experience were compared by racial and ethnic group in a sample of students
(N = 586) drawn from 13 high schools with diverse ethnic and socioeconomic student populations. Using the Experience Sampling
Method (ESM), 3,529 samples of classroom experiences were analyzed along with self-reported grades. Similarities and differences
in achievement, engagement, and quality of experience among white, black, Latino, and Asian students were examined. The most
marked differences found were between black and white students. Consistent with several previous studies, an engagement–achievement
paradox was found in which black students reported higher engagement, intrinsic motivation, and affect in classrooms, but
lower GPA relative to white students. A similar engagement–achievement paradox was found for students from low SES communities
compared to those from high SES communities. Analyses also revealed racial and ethnic differences in the relationship of engagement
with on-task behavior and contextual factors. Being on-task when in classrooms had a more positive effect on the engagement
of black students relative to white students. The contextual effect of being in school versus home or in public on engagement
was also more positive for black students than white students. Contextual factors and measurement issues are emphasized in
the interpretation of findings and suggestions for future research.

The involvement of adolescents with deviant peer groups is one of the strongest proximal correlates to juvenile delinquency
and stems from a variety of causes. Past research has linked ineffective parenting with peer variables, including deviant
peer group involvement and peer conflict during adolescence. In this study, adolescents’ appraisals of procedural justice
within the family (adolescents’ appraisals of how fairly they are treated by parents in the process of resolving family conflict)
were examined as one aspect of effective parenting that may relate to deviant peer group involvement in early adolescence.
Data from 1660 middle school students (ages 11–14, mean = 12.6) indicated that higher appraisals by adolescents of procedural
justice during family conflict resolution were related to lower levels of both peer conflict and deviant peer group involvement.
A structural model was tested in which the relationship between adolescents’ appraisals of procedural justice in the family
and deviant peer group involvement was partially mediated by measures of peer conflict. This model was found to have adequate
fit to the data, indicating that part of the relationship between procedural justice appraisals and deviant peer group involvement
can be explained by levels of peer conflict. Implications of these findings are discussed.

The current study, using data from 374 African American students (59.4% female) in grades 7–12 attending a rural, southern
county public school, addressed associations of self-efficacy, ethnic identity and parental support with “future education
orientation.” Both gender and current level of achievement distinguished adolescents with differing levels of future education
orientation. The strongest predictors of future education orientation were self-efficacy, ethnic identity and maternal support.
Gender did not moderate these associations. Implications for future research include the need to conduct longitudinal studies
and research that integrates quantitative and qualitative methods to elucidate further the nature and importance of future
education orientation for African American youth. Also needed are policies and programs that facilitate school bonding and
academic performance, as are efforts that focus specifically on enhancing the future education orientation and academic success
of African American male adolescents.
