Food insecurity, or limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire acceptable foods in socially acceptable ways, affects more than 10% of Americans. The U.S. Department of Agriculture's 18‐item Household Food Security Survey Module (HFSSM) is the most common measure used in the United States to assess food insecurity. This measure is to be completed by one adult who reports on the severity of disruptions in the quality and quantity of the household food supply. Recent work suggests that men and women might respond differently to some of the items in this measure. Therefore, the aim of the current study was to further explore how men and women interpret each of the items and specific concepts in this measure. Pairs (n = 25) of low‐income and food‐insecure mothers and fathers of children aged 2.5–10 years participated in one‐on‐one interviews to answer the HFSSM questions using the think‐aloud method. The data were analyzed using basic inductive qualitative methods, and the findings suggest that gender is related to interpretation of key concepts relevant to food insecurity including “household,” “balanced meal,” and “worry.” These findings have policy implications for the use of this measure as a national benchmark of food insecurity such as the potential need for an additional, complementary instrument to include several male reference questions with different terminology.  相似文献

Substantial evidence from cross-sectional and short time-span longitudinal studies exists about negative associations between early pubertal maturation on a number of psychological outcomes. The objective of the present study was to assess the association between early maturation and developmental trajectories of social skills and internalizing and externalizing problems in girls from grades 1 through 9, including pre- and post-pubertal periods. The sample came from the NICHD Study of Early Child Care and Youth Development and included 398 Caucasian and 60 African American girls. Multilevel modeling revealed early maturing Caucasian girls were at risk for higher internalizing and externalizing problems and experiencing higher levels of problems pre-pubertally. African American youth had lower social skills and internalizing problems with no group differences due to early pubertal development. Findings are discussed in light of literature on continuity of girls' psychosocial development before and during the pubertal transition.  相似文献

Measuring student progress toward the achievement of learning outcomes in negotiation skills courses is a difficult task. Measuring the effectiveness of the delivery of course instruction can be equally challenging. This article proposes some answers to these questions: How can student performance in skills such as negotiation, leadership, and teamwork (sometimes referred to as “soft skills”) be effectively measured and accurately evaluated? What standards can be used to determine whether student performance is superior, adequate, or inferior? How can teaching effectiveness be evaluated to determine whether students are receiving the instruction necessary to achieve the course learning objectives? This article describes how the authors collaborated on an adaptation of the assessment processes used in the U.S. Army Reserve Officer Training Corps (ROTC) cadet Leadership Development Program for use in an MBA course on negotiation skills. We report on a pilot effort that has demonstrated that the ROTC‐style leadership assessment process can be successfully adapted for use in a graduate course on negotiation and that it provides useful means for evaluating both individual student performance and overall course effectiveness. While our work involved a negotiation course, we suggest that the process could be adapted for use in other skills‐oriented courses such as leadership.  相似文献

This study examined adults’ abilities to detect the veracity of children's (ages 6–11) initial disclosures and their later recantations about a crime. Children (N?=?32) were asked to make a false denial or a false accusation of an alleged theft, while some were asked to tell the truth. Afterwards, children recanted their initial statements in a second interview; thus, children who initially denied the theft accused a researcher of the transgression in the second interview, and vice-versa. Adult raters (ages 18–25; N?=?108) watched both interviews and completed a questionnaire that required them to determine the veracity (i.e. whether the report was true or false) and credibility of the disclosure. Adults accurately detected the veracity of children's reports 53% of the time (55% of original reports, 50% of recantations). Raters were more accurate when detecting false denials than false accusations in the children's original and recanted reports. Despite being more difficult to detect, children's recanted denials that became accusations were rated as the least credible. Furthermore, self-reported level of experience with children and ratings confidence were not significant predictors of truth/lie detection accuracy.  相似文献

The outcome of batterer programs has become a topic of research and clinical concern in recent years. There has been little assessment, however, of the input of these programs and its implications. This study analyzes the records of 200 inquirers to a batterer program during 1989–1990 to determine the attrition rates based on the initial number of inquirers. The attrition from inquiry to intake is 73%, from inquiry to counseling attendance is 86%, and from inquiry to 12 counseling sessions is 93%. Only 1% actually completed the contracted 8 months of counseling sessions. The only background and protocol variable significantly associated with intake attrition was marital status. Those inquirers referred from informal referral sources and paying high monthly fees were more likely to attend over 12 counseling sessions. The 1990 inquiry-to-counseling attrition rates were higher than the program rates in the early 80s and higher than a comparable program with no separate intake session. The implications of these findings for pre-program protocol are discussed.  相似文献

In order to make greater use of dog hairs as forensic evidence, we have developed a robust method for duplex amplification of adjacent 306 and 332bp amplicons within the 5' hypervariable region (5' HVR) of the canine mitochondrial control region. In support of this, a 595bp region covering 35 polymorphic sites has been sequenced from the blood of 105 UK dogs. In total, 30 different haplotypes were observed, 13 only once whilst the commonest was seen 14 times; the overall exclusion capacity is 0.929. One animal was heteroplasmic in blood for a single base deletion and showed phenotypes ranging from near complete deletion to a predominance of the base among a sample of 12 hairs. In contrast, no evidence of heteroplasmy was seen in single hairs from 20 dogs which were not visibly heteroplasmic in blood. Phylogenetic analysis and comparisons with other published databases highlighted instances of possible recurrent mutation which may be relevant when interpreting single base differences between samples.  相似文献

This paper examines the policies and directions framing the professional practice of Australian combat photographers in the Second World War. It argues that while their endeavours to offer an account of the nation at war were constrained by predictable considerations of politics and censorship, their commitment to truth was also framed and constricted by an array of cultural considerations. The nation’s ongoing engagement with the history of the First World War, the contrasting organisational cultures of the bureaucracies that the photographers served, and Australian culture’s visual inarticulacy concerning death on the battlefield played key roles both individually and collectively in shaping the photographers’ practices and outputs. The paper will trace the operations of these influences and contend that, as a result, the photographers’ visual record of the Second World War, particularly as it related to the death of Australian servicemen, served to conceal rather than reveal the ultimate truth about the Australian experience of the war.  相似文献

A world-system analysis of the ecological rift generated by capitalism requires as one of its elements a developed theory of the unequal ecological exchange between center and periphery. After reviewing the literature on unequal exchange (both economic and ecological) from Ricardo and Marx to the present, a new approach is provided, based on a critical appropriation of systems ecologist Howard Odum's emergy (spelled with an m) analysis. Odum's contribution offers key elements of a wider dialectical synthesis, made possible in part by his intensive studies of Marx's political-economic critique of capitalism and by Marx's own theory of metabolic rift.  相似文献
