This quarter's column features a report from Electronic Resources and Libraries held March 16–19, 2014, in Austin, TX; another from Potomac Technical Processing Librarians (PTPL) held in Annapolis, MD, on October 17, 2014; and several reports from ALA Midwinter held January 30–February 3, 2015, in Chicago, IL. By necessity, these reports are not exhaustive in covering the respective conferences.  相似文献

Abstract

The extremely low prevalence of steroid use among college students makes it virtually impossible to conduct analyses on any single college campus. By studying a cohort of 58,625 college students from 78 institutions that administered the Core Alcohol and Drug Survey in 1990 and 1991, a critical mass of 175 users on which it was possible to conduct statistical analyses was identified. Compared with a randomly selected group of nonusers, the steroid users reported consuming dramatically more alcohol and demonstrated higher rates of binge drinking. In addition, a significantly higher percentage of steroid users reported using tobacco, marijuana, cocaine, amphetamines, sedatives, hallucinogens, opiates, inhalants, and designer drugs. A higher percentage of steroid users than nonusers also reported experiencing negative consequences as a result of substance abuse, and a greater percentage of the steroid users reported family histories of abuse of alcohol and other drugs. Implications from the standpoint of student development are discussed.  相似文献

Abstract

In recent years mental health professionals have become increasingly aware of their role in ameliorating the impact of disaster and have begun to develop models for systematizing interventions. As many have noted, however, these models are largely based on clinical wisdom due to the dearth of empirical data on disaster and its social and psychological consequences. This article describes one model of disaster intervention, the Triple ABCD Model, and provides evidence-based guidelines for determining possible hazards and risks to both individuals and communities. Key factors considered are intentionality, predictability, time frame, degree of threat, location, extent of disruption and destruction, and timeliness and sustainability of the outside resources. Implications for practice include the importance of considering both individual and community factors in assessing risk and resilience; the need for mental health practitioners to exercise both clinical and community building skills when responding to disaster; and the importance of training and education of mental health professionals that include emergency planning and response with a focus on supporting the public at both an individual and community level.  相似文献

Two hundred and seventy African-American and Caucasian families referred to child protection for alleged maltreatment were compared to assess the degree to which they were differentially referred to and processed by child protection. Results indicated that, although African-Americans were referred to child protection by different sources than Caucasian families, reporter bias was unlikely to account for the differences. Those African-American families referred to child protection were more likely to come from female headed households and presumed to be poorer as a result. However, once reported, they were neither substantiated at a higher rate nor kept open for services at a higher rate compared to Caucasian families. Finally, there was very little evidence of differential caseworker attention to African-Americans compared with Caucasian families. The study concluded that differential referral source and/or differential worker attention were inadequate explanations for the over-representation of African-Americans in the child protection system.  相似文献

Abstract

Korean–Australian intercountry adoption has been practiced for 30 years. This longevity provides unique opportunities to develop critical perspectives on a complex, global practice. This paper presents understandings drawn from a study that explores Korean intercountry adoption using Actor Network Theory. It argues that the practice of intercountry adoption in Australia has been shaped by adoption-driven influences and characterised by controversy and competing discourses. It concludes that contemporary understandings necessitate a global, contextual, and critical view that is inclusive of emerging voices and alternate discourses. The challenge for practitioners and policy makers is to ensure the complex nature of the phenomenon is understood by all stakeholders. This will involve remaining child-focused, promoting multilevel interventions, incorporating research findings, and resisting wholly positive discourse that promotes singular perspectives. An awareness of how the internet is used to forge networks and promote discourses is crucial in ensuring multiple perspectives are considered in this contentious practice field.  相似文献

Background

Little qualitative research has been done to explore the quality of breastfeeding support through social media in New Zealand.

Aim

This article aims to explore the influence of social media on exclusive breastfeeding practice.

Methods

A qualitative study involving face-to-face postpartum interviews with 30 mothers who were recruited from the lower North Island of New Zealand. Each participant was followed via short monthly audio-recorded telephone interviews until giving up exclusive breastfeeding or until six months after the birth. The theories “strength of weak ties” and “landscapes of care” are applied to the thematic analysis of the interview material to illuminate the influence of social media on breastfeeding practices.

Results

Qualitative analysis of the interview material identified four themes: 1) Mothers need reliable online infant feeding information; 2) Smartphone apps can be a good option for promoting breastfeeding; 3) Information is accessed through weak ties among breastfeeding mothers on Facebook, and 4) the utility of geographically distant infant feeding support via Skype.

Discussion

Most participants sourced post-partum information and advice to support breastfeeding through the Internet, while those with geographically distant family members accessed emotional and practical breastfeeding support via Skype.

Implications for Practice

Breastfeeding advocates should use social media to promote and support exclusive breast-feeding practice.

Conclusion

The influence of social media on breastfeeding points to the relational nature of breastfeeding which is embedded in ‘real’ world and virtual social networks as well as the cultural, geographic and social contexts of a mother’s life.  相似文献

We introduce a two‐period Stackelberg game of a supplier and buyer. We recognize that learning from manufacturing experience has many advantages. Consistent with the literature, we assume both the buyer and supplier realize reductions in their respective production costs in period 2 due to volume‐based learning from period 1 production. In addition, we introduce another learning concept, the future value, to capture the buyer's benefits of transferring current manufacturing experience for the design and development of future products and technologies. In contrast to the literature, we allow the supplier two mechanisms to impact the buyer's outsourcing decision: price and the investment in integration process improvement (IPI) that reduces the buyer's unit cost of integration. IPI may include the investment in new materials, specialized technology, or the re‐design of the integration process. Conditions are given whereby the buyer partially outsources component demand as opposed to fully outsourcing or fully producing in‐house. Furthermore, conditions are given characterizing when the supplier's price and investment in IPI are substitute strategies versus complements. Both analytic and numerical results are presented.  相似文献

Introducing environmental innovations in product and process design can affect the product's cost and demand, as well as the environmental impact in different stages of its life cycle (such as manufacturing and use stages). In this article, we advance understanding on where such design changes can be most effective economically to the firm and examine their corresponding environmental consequences. We consider a profit maximizing firm (newsvendor) deciding on the production quantity as well as its environmentally focused design efforts. We focus our results along the two dimensions of demand characteristics and life‐cycle environmental impact levels, specifically functional vs. innovative products, and higher manufacturing stage environmental impact vs. higher use stage environmental impact. We also discuss the environmental impact of overproduction and how it relates to the different types of products and their salvage options. We find that although the environmental impact per unit always improves when firms use eco‐efficient or demand‐enhancing innovations, the total environmental impact can either increase or decrease due to increased production quantities. We identify the conditions for such cases by looking at the environmentally focused design efforts needed to compensate for the increase in production. We also show that the environmental impact of overproduction plays an important role in the overall environmental impact of the firm. We conclude by applying our model to different product categories.  相似文献
