Scientific research has made major contributions to adolescent health by providing insights into factors that influence it and by defining ways to improve it. However, US adolescent sexual and reproductive health policies—particularly sexuality health education policies and programs—have not benefited from the full scope of scientific understanding. From 1998 to 2009, federal funding for sexuality education focused almost exclusively on ineffective and scientifically inaccurate abstinence-only-until-marriage (AOUM) programs. Since 2010, the largest source of federal funding for sexual health education has been the “tier 1” funding of the Office of Adolescent Health’s Teen Pregnancy Prevention Initiative. To be eligible for such funds, public and private entities must choose from a list of 35 programs that have been designated as “evidence-based” interventions (EBIs), determined based on their effectiveness at preventing teen pregnancies, reducing sexually transmitted infections, or reducing rates of sexual risk behaviors (i.e., sexual activity, contraceptive use, or number of partners). Although the transition from primarily AOUM to EBI is important progress, this definition of evidence is narrow and ignores factors known to play key roles in adolescent sexual and reproductive health. Important bodies of evidence are not treated as part of the essential evidence base, including research on lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth; gender; and economic inequalities and health. These bodies of evidence underscore the need for sexual health education to approach adolescent sexuality holistically, to be inclusive of all youth, and to address and mitigate the impact of structural inequities. We provide recommendations to improve US sexual health education and to strengthen the translation of science into programs and policy.  相似文献

By making an embroiderer her central narrative voice and embroidery both the structural and the thematic focus of her most recent novel (Le Passé empiété [The Back Stitch]), Marie Cardinal complements Rozsika Parker's efforts (The Subversive Stitch: Embroidery and the Making of the Feminine) to trace the parallel histories of embroidery and femininity through the novel. For both Parker and Cardinal, embroidery figures the creative tension between conformity and subversion that Cardinal posits as common to all women and that results in Le Passe empiete in a complex reevaluation not only of the female artist herself but of both the traditional and the feminist critical context within which she currently creates. In particular, Cardinal explores the relationship between women's traditional domestic tasks and their artistic production, and she uses the specific qualities of embroidery to rethink common assumptions about literary influence and authority, the writing process, and the mythic tradition.  相似文献

This article explores the complex relationship between democracy and long-term policy design for sustainability. At one extreme, democracy can be framed as problematic for policy planning because of the myopia fostered by some democratic institutions, such as regular elections. Alternatively, democracy can be seen as an ally of long-term policy design to the extent that it can generate public legitimacy and accountability, and potentially foster more equitable and just outcomes. Recent debates on how to ‘manage’ policy transitions to sustainability have been curiously silent on democratic matters, despite their potential implications for democracy. To explore what democracy might mean for transition management this article considers empirically how actors engaged in the Dutch Energy Transition Program make democratic sense of their activities. The analysis finds that in practice transition policies promote implicit narratives or democratic storylines on how reforms should be developed, who should participate in these, and how they should be legitimised and accountable to the public. The dominant narrative, which espouses elite theory and technocracy, privileges epistemic matters over democratic considerations. Other democratic storylines draw on representative democracy and interest group pluralism. The paper considers some possible ways to foster more productive interfaces between the governance structures of transition management, and the polycentric context of contemporary democratic systems.  相似文献

Plastic bags are frequently used to package drugs, explosives and other contraband. There exists, therefore, a requirement in forensic casework to compare bags found at different locations. This is currently achieved almost exclusively by the use of physical comparisons such as birefringence patterns. This paper discusses some of the advantages and shortcomings of this approach, and presents stable isotope ratio mass spectrometry (IRMS) as a supplementary tool for effecting comparisons of this nature. Carbon and hydrogen isotopic data are presented for sixteen grip-seal plastic bags from a wide range of sources, in order to demonstrate the range of values which is likely to be encountered. Both isotopic and physical comparison (specifically birefringence) techniques are then applied to the analysis of rolls of bags from different manufacturing lots from a leading manufacturer. Both approaches are able to associate bags from a common production batch. IRMS can be applied to small fragments which are not amenable to physical comparisons, and is able to discriminate bags which could be confused using birefringence patterns alone. Similarly, in certain cases birefringence patterns discriminate bags with similar isotopic compositions. The two approaches are therefore complementary. When more than one isotopically distinct region exists within a bag (e.g. the grip-seal is distinct from the body) the ability to discriminate and associate bags is greatly increased.  相似文献

Cocaine (COC) is a highly addictive plant alkaloid expressing strong psychostimulatory effect. It has no medical use in equine veterinary practice. The contamination of the environment with cocaine such as its presence on the US paper currency has been reported few times. There are anecdotal reports of low benzoylecgonine (BE) concentrations (usually much less than 100 ng/mL) being found in urine of race horses. In order to protect horsemen against harsh penalties associated with the presence of trace amounts of BE in horse urine as a result of environmental contamination, in February 2005 the Illinois Racing Board issued new medication rules that established the threshold level of 150 ng/mL for BE in equine urine. The penalties associated with this rule provide for increasing fines ($250, $500, $1000) with successive positive reports against a trainer for levels of BE below 150 ng/mL. A total of 19,315 urine samples were collected over the 2-year period of time from winning horses (both harness and thoroughbred) at race tracks in Illinois for routine drug screening (ELISA). The presence of BE was confirmed by GC/MS in 28 urine samples (0.14%). The concentration range for BE in harness horses (21 detections) was < 5-91 ng/mL, and for thoroughbred (seven detections) was 7-52 ng/mL. To date, the laboratory has not reported concentrations of BE that exceed the established threshold concentration of 150 ng/mL.  相似文献

Postmortem fingerprint collection is a routine part of many forensic death investigations. Although the production of postmortem prints is usually straight forward, several obstacles and scenarios can make the collection difficult. A common challenge occurs when finger pads are mummified. Several current techniques allow for softening and rehydration of mummified finger pads; however, despite the employment of such techniques, the production of adequate postmortem fingerprints can remain elusive. The authors present two techniques that can improve the chances of obtaining suitable fingerprints from mummified remains. The “baby powder method” involves applying a cornstarch‐based powder, such as baby powder, onto the darkened and mummified finger pads, to allow better visualization of the fingerprint detail. The “transillumination method” involves carefully dissecting away the tissues underlying the finger pad, followed by placement of a bright light source underneath the finger pad, such that the finger ridge pattern is illuminated.  相似文献

Varied curricula among public school districts within the same state often result in localized core courses and high school graduation requirements. This inconsistency makes it difficult for highly mobile students–who make frequent non‐promotional school transfers during the school year–to obtain full or partial credit for successfully completed coursework, hindering progress toward graduation and increasing dropout rates. While student mobility permeates all communities, it is particularly devastating to some of the most vulnerable children in our society, including homeless children, foster youth, children from low‐income and single‐parent households, migrant students, youth in juvenile correctional facilities, and children of military families. Current federal legislation addresses only some of these groups, leaving many students underserved by the education system. This Note advocates for states to adopt legislation that specifically requires a standardized credit‐recognition system, allowing schools to award full and partial credit for coursework completed elsewhere within the state. Specifically, it addresses the importance of keeping highly mobile students in their schools of origin, when it is in their best interest. It further focuses on the need for state and local policies to require school districts to award and accept full and partial credit for coursework completed in another in‐state school district.  相似文献

Abstract

At the outset of the 2015 refugee crisis, Germany pursued an accepting asylum policy, potentially to mitigate its declining population. Austria, facing the same demographic challenges, closed itself to refugees. Differences in radical right-wing populism (RRP) in the two countries provide the basis for understanding their asylum policies. After the Second World War, Germany’s collective memory stigmatized far-right parties, while Austria’s did not. The radicalization spiral reproduces these differences today, allowing Austria’s Freedom Party to influence migration policy by pulling voters and mainstream parties to the right, while Germany’s RRP parties were unable to do the same before the crisis.  相似文献
