In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction. 相似文献

The specific goal of the study is to look how tensions, competing values and trade-offs manifest in the management of nuclear power plants. Second goal is to inspect how existing frameworks, such as Competing Values Framework, can be used to model the tensions. Empirical data consists of thirty interviews that were conducted as part of a NKS study on safety culture in the Nordic nuclear branch. Eight trade-offs are identified based on a grounded theory based analysis of the interview data. The competing values and potential tensions involved in the trade-offs are discussed. 相似文献

In this study the authors assessed the effects of disability beliefs, conceptualization and labeling of emotional disabilities, and perceived barriers on help-seeking behaviors among depressed Chinese Americans in a primary care setting. Forty-two Chinese Americans participated in semistructured interviews using established psychological measures and open-ended questions adapted from the Explanatory Model Interview Catalogue. The authors found that care utilization appears to be complicated by somatization of emotional problems, variations in causal attribution to depression, barriers to receiving mental health care, and the burden of comorbid physical conditions. Their findings highlight the importance of addressing these issues and educating patients about body-mind dialectic common to depression. 相似文献

Through a comprehensive literature search, the authors of this systematic review identified 21 articles focused on primary prevention of HIV/AIDS for adults aged 50 and over. Three major challenges to providing HIV/AIDS education for older adults include health professionals' ageism, older adults' reluctance to discuss sexuality, and their misconception of their HIV risk. Clinical guidelines for social workers, nurses, and physicians identified the importance of sharing information and assessing risk, considering cultural diversity, and devising creative delivery strategies. Three models of HIV/AIDS education include group education programs delivered by social workers or other health professionals, peer education models, and one-on-one early intervention models including HIV/AIDS testing. Additional outreach and research on HIV/AIDS prevention among older adults is needed. 相似文献

数字营销未来要解决的问题
本篇我们来谈谈数字营销未来可能要面对的问题和风险,下面分三个方面来探讨:
一、碎片化问题
虽然能够从近15年的研究分析中找出周期性的研究主题,但我们也注意到,顶级期刊中关于DSMM的研究主题碎片化程度很高,许多有趣的研究之间可以说毫无相关性.高质量的专业期刊中,要么是宽泛的概念研究,要么是很窄的深度模型研究,缺乏全视野的研究.一般期刊中的研究则倾向于提供片面的理论或模型的片段.我们其实缺乏对前人提出的理论进行深刻或全面的认识,也缺乏支持或反驳先前概念的研究. 相似文献

数字营销的第一阶段:2000-2004
2000年之所以可以成为数字营销历史的起点,主要有如下几点原因:
首先,关注数字互动营销的学术研究在2000年前后开始大量增加.《直效营销杂志》(Journal of Direct Marketing)在1998年更名为《互动营销杂志》(Journal of Interactive Marketing)并开始发行. 相似文献

小隐孢子虫(Cryptosporidium parvum)污染是对水工程的一个挑战也威胁到公众健康。在此项研究中,我们开发了一种细胞培养-定量PCR分析法来评估消毒后小隐孢子虫的活性。我们用这种方法对水工程中多种消毒法包括低压紫外光(LP-UV),臭氧,混合氧化剂(MIOX),氯气进行评估。证实该检测方法是可信和敏感的,最低能检测到一个感染卵囊。有效的卵囊消毒(灭活率>2 log10 units)是采用LP-UV(20 mJ/cm2)或2 mg臭氧/公升(10分钟)。MIOX和氯气消毒卵囊效果最差(灭活率<0.1 log10 unit)。这些结果证实了MIOX对小隐孢子虫消毒的无效性。该检测方法是对饮用水和循环水消毒系统有效的评估方法。 相似文献

Moving and union dissolution 总被引:1,自引:0,他引:1
This paper examines the effect of migration and residential mobility on union dissolution among married and cohabiting couples. Moving is a stressful life event, and a large, multidisciplinary literature has shown that family migration often benefits one partner (usually the man) more than the other Even so, no study to date has examined the possible impact of within-nation geographical mobility on union dissolution. We base our longitudinal analysis on retrospective event-history data from Austria. Our results show that couples who move frequently have a significantly higher risk of union dissolution, and we suggest a variety of mechanisms that may explain this. 相似文献

我很喜欢宋文京先生……每次青岛文化沙龙上和宋先生交流都带着愉悦、带着欣赏、苦涩地探究但是又渴望融入的交织心情。很简单地,他让我明白一件小事情,就是我自己在英译汉的学习中为什么有段时间感觉"译"的语感堵塞了,我无法痛快地把一个我内心很明白的东西说出来。 相似文献
