Workplace violence is a leading form of occupational injury and fatality, but has received little attention from the ergonomics research community. The paper reports findings from the 2012 New Zealand Workplace Violence Survey, and examines the workplace violence experience of 86 New Zealand organisations and the perceptions of occupational health and safety professionals from a systems perspective. Over 50% of respondents reported violence cases in their organisation, with perpetrators evenly split between co-workers and external sources such as patients. Highest reported levels of violence were observed for agriculture, forestry and construction sectors. Highest risk factor ratings were reported for interpersonal and organisational factors, notably interpersonal communication, time pressure and workloads, with lowest ratings for environmental factors. A range of violence prevention measures were reported, although most organisations relied on single control measures, suggesting unmanaged violence risks were common among the sample. 相似文献

The present research examined how problem characteristics might influence the online helping behavior of shy individuals. Three hundred undergraduates were recruited and assessed using the College Students’ Shyness Scale. According to the scores, 68 high-shy students and 68 low-shy students were selected to participate in simulated experiments designed to determine the influence of the shyness level, the presence of a foreseeable reward, the complexity of the problem, and the urgency of the problem influence online helping behavior. The results showed that (a) High-shy individuals tended to exhibit online helping behavior more for low-complexity problems and high-urgency problems than for high-complexity problems and low-urgency problems. (b) Low-shy individuals always exhibited online helping behavior less for high-complexity problems and when no reward was offered than they did for low-complexity problems and when a reward was offered. (c) High-shy individuals showed online helping behavior more than low-shy individuals did for no-reward, high-complexity problems and high-urgency problems. (d) Participants online had higher shyness scores for showing helping behavior than those offline. 相似文献

Comments by on an article entitled "Racial microaggression? How do you know?" by Rafael S. Harris Jr. (see record2008-05553-011). The author states that in our original article we asserted that the racial reality of POC was generally different from the racial reality of White Americans and that often times interpretations of situations and events are the result of worldviews or racial identity. When references are made to POC, or to “visible racial/ethnic groups,” reference is being made not only to the shared cultural characteristics, norms, values, and attitudes of the group (African American, Asian American, American Indian, and Latino/Hispanic American) but to a self-designation of racial identity formed from sociopolitical experiences of unequal social, economic, legal, and political power in U.S. society that are based on visible racial characteristics.

Eric Verdeil 《Planning Perspectives》2013,28(2):249-266
The architect and planner Michel Ecochard has had a long career in developing countries, from its first works in Syria under the French rule, until the 1970s. He represented the modernist and functionalist approach to planning in a time of modernization. In this article, we concentrate on his work in Lebanon and Syria between the end of the 1950s and the 1960s. He prepared the master plans of Beirut and of Damascus. Those works represented the end of an era rooted in colonial planning. It was also the beginning of a new time, with the local planners taking on, sometimes sharing, sometimes contesting Ecochard's visions. Building on recent scholarship on the circulation of planning ideas, we focus on the reception of Ecochard's proposals. Though most political elites and planning professionals shared most of Ecochard's views, the political circumstances and the changing social conditions led to adjustments and reorientations. The new planning framework was also a major factor of change. 相似文献

Mentoring can have a significant positive impact on the lives of individuals. People with disabilities seeking to locate mentors face a variety of potential challenges and benefits. This article addresses mentoring-related issues faced by professionals with disabilities. The article presents a model of mentoring and discusses the difficulties faced by individuals with disabilities in locating mentors. It describes the negative impact of the lack of available mentors upon the educational and vocational development of people with disabilities.

Notes that the Visiting Psychologist Program has completed its eighth year of operation under the sponsorship of the National Institute of Mental Health. The program is designed to facilitate the dissemination of up-to-date knowledge generated in recent research findings and to provide for the demonstration of innovations in psychological procedures to mental health professionals in service settings by psychologists who are significantly involved in research, training, and delivery of services. Agencies that received initial visits are listed, with their Visiting Psychologists as well. Agencies and Visiting Psychologists involved in return visits are also listed. The Advisory Committee would like to thank all of those who contributed to the success of the program. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Examines the two sets of criteria that generally categorize mental health: those that emphasize internal events and those that deal with external events. The author discusses the future of mental health in light of many of its current trends, including greater acceptance of diversity, and he discusses the potential future role of the mental health professional. The author notes that greater numbers of mental health professionals have gotten involved with different populations, and suggests that the majority of mental health professionals will probably be experts in handling small units of behavior or experience for a limited time. The very process of making predictions changes the future course of events. Let us hope that this intricate process will result in greater satisfaction for greater numbers of people.
