Suicidal and help‐seeking behaviors of students of color remain a significant problem on college campuses. Self‐reported suicidal experiences and help‐seeking behavior of diverse students are examined on the basis of results from a national survey of college student mental health. The results suggest significant differences in the expression of suicidal thoughts and behavior across racial and ethnic groups and different experiences in their referral for, and utilization of, professional help.  相似文献

Abstract

Developed countries are rapidly evolving into information economies, and given the increasing internationalization of trade and interdependence, developing countries will also have to become information economies if they are to achieve higher economic growth rates. The essence of the information economy is that information is now the main capital input into manufacturing industry and as such is the key input to economic development. The activities of enquiring, communicating, evaluating, and deciding have become the activities absorbing the major proportion of national resources, with the need to know of the business decision‐maker as the main driving force. In developed information economies, industrial firms have become learning systems and a new division of labor in the economic productive system has evolved. The government‐controlled primary information sector is the source of much of the information input and the provider of the means of information transfer. Developing countries must develop their own primary information sectors as an integrated part of the agricultural and manufacturing sectors. The problems of developing countries are highlighted in the isolation on the one hand of their information generating sectors from the productive sector and on the other of the native small firm sector from all sectors of information. Telematics, as the integration of computing, communication, and information services offers the means to integrate national resources with international and supply the required inputs to local agricultural and industrial development.  相似文献

茶小绿叶蝉优势种的归属的分子依据   总被引:2,自引:0,他引:2

从中国农业科学院茶叶研究所的国家茶树资源圃随机采集茶小绿叶蝉个体,用RAPD标记技术,拟从DNA水平上探索茶小绿叶蝉个体间的遗传距离和亲缘关系,为茶小绿叶蝉优势种的归属提供分子水平上的依据。所选的14个随机引物共扩增出81条谱带,59条多态性条带,多态性为72.84%,表明叶蝉个体间有较丰富的遗传多样性,但未发现可以区别不同种的特异性条带和引物。UPGMA法聚类分析也表明,叶蝉个体间遗传距离在0.17~0.46之间,说明茶小绿叶蝉的遗传基础较一致,存在异种的可能性几乎没有。本文为茶小绿叶蝉的优势种的归属提供了一定的分子基础,结合前人对茶小绿叶蝉的形态学研究,认为茶小绿叶蝉的优势种为假眼小绿叶蝉,小绿叶蝉未在茶园中未形成种群。  相似文献

Guided by communicated narrative sense-making, the present study explored the themes that characterize adult siblings’ stories about their experiences with sharing care of aging parents. Interviews with 20 adult siblings revealed the varied and emotional nature of their shared parental caregiving stories. Adult siblings primarily constructed meaning of their caregiving experiences by drawing upon three overarching narratives: (1) the narrative of (in)equity, (2) the narrative of ideal versus real, and (3) the narrative of interconnectedness. These findings highlight the need for adult siblings providing care for their parents to work together as a team, exercise empathy in their interactions, and express gratitude for one another’s contributions. Several practical applications are discussed that can help siblings manage and overcome the relational challenges associated with caring for a parent.  相似文献

ABSTRACT

Technical Services departments have been navigating rough and uncertain waters while charting courses toward hazy horizons for years. Battling swelling expenses, blustering winds of reduced resources, and tumultuous tempests of electronic resources clashing with print resources, we steer toward an increasingly digital skyline with steadily leaner crews, needing support and new skills to sail these seas of continuous change and challenge. Now more than ever it is necessary to build a team empowered to maneuver efficiently and effectively. Leading and managing are central to positioning for and embracing these emerging horizons. The presenters have been studying and implementing various aspects of “servant leadership” with an eye toward growing people within our departments and communicating in multiple directions. During this session, we will focus particularly on the following processes: discernment, discovering purpose, and building capacity (relationships and communication). This presentation will explore the what, how, where, who, and when for leading and managing toward our Technical Services horizons.  相似文献

This article draws on the concepts of narrative interactivity and closure to investigate three World War II-era print media characters. The analysis details how Al Parker’s Mary & Jane and Norman Rockwell’s Willie Gillis developed a perceived authenticity that invited fans to envision the propaganda drawings as having lives beyond their artistic origins. The essay concludes that the narrative arcs of these characters prefigured the imagined relationships that subsequent generations developed with televised characters.  相似文献
