There is inconsistency in the outcome measures of biological and psychosocial studies using measures of puberty as a predictor. For example, some studies show that maturational timing may have differential influences (positive, negative, or no effect) depending on the specific disorder, dimension of measure, and gender. Other studies have suggested that some effects may be more directly linked to pubertal stage or hormone concentrations rather than timing per se. This study outlines several conceptual and methodological issues that may be relevant to addressing these inconsistencies, in the context of examining data from a study of maturational hormones obtained from a unique longitudinal cohort of 24 girls (age 10.0 ± 1.6 years) and 36 boys (age 10.4 ± 1.6 years) in the early part of puberty, where the developmental trajectory of these hormones were tracked annually in 65% of the sample. We explored the contributions of measures of pubertal growth and sociodemographic factors on hormone concentrations. In brief, it appears that no single measure best captures the maturational processes during puberty and suggests that multiple processes are occurring in parallel. Several conceptual and methodological implications are discussed that may guide investigators in interpreting existing studies of pubertal timing and behavior as well as in conducting future studies. 相似文献

Nonprofit organisations comprise a growing and important sector of the Australian economy. This sector is being used by governments to an increasing extent for the delivery of services. The most common manner in which nonprofit organisations are funded by government is through the provision of grants, contracts or service agreements. Nonprofits discharge their accountability for these funds through reporting guidelines issued by the government funders. This article examines the financial accountability requirements of government funders, in one jurisdiction in Australia to support the central argument that the emphasis on ‘upward and external’ accountabilities serve as a functional and control tool on the sector. This emphasis detracts from the development of the ‘downward and internal’ mechanisms of accountability which are the essential building blocks for the strategic development of the capacity of the sector to respond to calls for greater accountability. 相似文献

Improved MtDNA sequence analysis of forensic remains using a "mini-primer set" amplification strategy 总被引:5,自引:0,他引:5
Gabriel MN Huffine EF Ryan JH Holland MM Parsons TJ 《Journal of forensic sciences》2001,46(2):247-253
Mitochondrial DNA (mtDNA) analysis of highly degraded skeletal remains is often used for forensic identification due largely to the high genome copy number per cell. Literature from the "ancient DNA" field has shown that highly degraded samples contain populations of intact DNA molecules that are severely restricted in size (1-4). Hand et al. have demonstrated the targeting and preferential amplification of authentic human DNA sequences with small amplicon products of 150 bp or less (1,2). Given this understanding of ancient DNA preservation and amplification, we report an improved approach to forensic mtDNA analysis of hypervariable regions 1 and 2 (HV1/HV2) in highly degraded specimens. This "mini-primer set" (MPS) amplification strategy consists of four overlapping products that span each of the HV regions and range from 126 to 170 bp, with an average size of 141 bp. For this study, 11 extracts representing a range of sample quality were prepared from nonprobative forensic specimens. We demonstrate a significant increase in MPS amplification success when compared to testing methods using approximately 250 bp amplicons. Further, 16 of 17 independent amplifications previously "unreported" due to mixed sequences provided potentially reportable sequence data from a single, authentic template with MPS testing. 相似文献

Although clinicians, educators and parents have been alarmed by the decline in the mental health of children and adolescents commensurate with the Covid-19 pandemic, statistics indicate there has been a downward spiral over the last decade. This has been evident in the overall increase in suicide rates for young people. For legal and mental health professionals working in the Family Court system, this has provided unique challenges. Most vulnerable has been those children and adolescents embroiled in high conflict divorces, especially those exhibiting parent child contact problems. This article focuses upon that population exhibiting parent child contact problems, and their treatment, specifically Family Intensive Intervention. Building Family Resilience is an Intensive family treatment program that has had to address this deterioration in child and adolescent mental health and increase in suicidality. The role of social media in both exacerbating and/or ameliorating mental health issues is explored. 相似文献

News media play a central role in democratic politics, yet we know little about how media affect the behavior of policy makers. To understand the conditions under which news media influence political elites, we advance a theory of strategic responsiveness, which contends that elected representatives are more likely to heed their constituents' preferences when voters are attentive. Accordingly, news media's influence on legislative behavior should be most apparent near elections and dependent on the partisan composition of the constituency. We capitalize on the incremental rollout of the conservative Fox News Channel in the late 1990s to evaluate our theoretical predictions. Fox News caused both Republicans and Democrats in Congress to increase support for the Republican Party position on divisive votes, but only in the waning months of the election cycle and among those members who represent districts with a sizable portion of Republican voters. 相似文献

Debate over municipal amalgamations in Australian continues to dominate local government reform agendas, with the putative need to achieve economies of scale and scope consistently set against anti‐amalgamation arguments designed to preserve extant communities. Following from an examination of recent episodes of consolidation in Australia, this paper reports on citizens' attitudes to amalgamation garnered from a national survey of 2,006 individuals. We found that generally, citizens are ambivalent toward amalgamation, although attitudes were influenced by particular demographic characteristics and attitudes to representation, belonging, service delivery requirements and the costs thereof. The results suggest that, away from the local government sector itself, structural reform may not be the vexatious issue it is often portrayed as. The implications of this are explored here. 相似文献

We examine whether public opinion leads Supreme Court justices to alter the content of their opinions. We argue that when justices anticipate public opposition to their decisions, they write clearer opinions. We develop a novel measure of opinion clarity based on multifaceted textual readability scores, which we validate using human raters. We examine an aggregate time series analysis of the influence of public mood on opinion clarity and an individual‐level sample of Supreme Court cases paired with issue‐specific public opinion polls. The empirical results from both models show that justices write clearer opinions when their rulings contradict popular sentiment. These results suggest public opinion influences the Court, and suggest that future scholarship should analyze how public opinion influences the written content of decision makers’ policies. 相似文献

Regulatory negotiation is a process by which representatives of affected interests, along with the regulatory agency, attempt to negotiate a consensus agreement on the content of a regulation. This study represents an empirical effort to begin to identify and sort out the roles that an agency plays in a collaborative policy-making process such as regulatory negotiation. Three regulatory negotiation cases were examined to determine the perceived roles of the U.S. Environmental Protection Agency (EPA) officials and other participants, and the study suggests a number of findings. First, that EPA fulfills a number of different roles (Expert, Analyst, Stakeholder, Facilitator and Leader) in a negotiation process; second, that EPA is expected to be an active participant in the negotiations, not simply an overseer or facilitator of interests; and finally, EPA interprets its primary role much more narrowly – as that of an expert – than do other participants. Non-agency participants view EPA's primary role as a leader, which combines technical and substantive components as well as process components. Where previously and in the theoretical literature, agencies exercise leadership through statutory authority or technical expertise, this study suggests that there are additional dimensions to that leadership role. In a collaborative process such as regulatory negotiation, the agency finds itself in a realm that demands that they effectively merge the roles of expert, analyst, and stakeholder into a more complex leadership role than has been suggested in the past. 相似文献

This essay examines the way that the language of rights has been used to both justify and challenge xenophobia in South Africa. South Africa has struggled with incidents of xenophobic violence against African migrants, with major outbreaks of violence taking place in 2008 and in 2015, and despite substantial anti-xenophobia efforts, African migrants continue to be subject to discrimination and abuse. Part of the reason for the persistence of anti-African migrant sentiment is a prevailing rhetoric of victimization, which frames irregular African migrants as a threat to the rights of South Africa’s poor. This essay analyzes that rhetoric, as well as analyzing how a grassroots movement of shackdwellers, Abhlali baseMjondolo, has challenged that rhetoric by highlighting the interconnection between the rights of citizens and noncitizens in the country. In examining the contestation over rights in South Africa, this essay seeks to engage with the ambivalence of citizenship in South Africa and the conflict between the human rights framework that has been established in the country and the necessary limitation of the rights of noncitizens. 相似文献
