In recent years, a series of important emergencies have been taken place worldwide in industrial plants. After the occurrence of a disaster, it is essential to activate the correct emergency procedures. Particularly, it is important to direct people injured in hospitals which are able to handle emergencies. Thus, nowadays, the emergency services require a management process starting from the disaster moment to the involvement of all actors participating in the process to provide integral, safe, and quality attention. The aim of this study is to help hospitals become better prepared for major disasters and public health emergencies and to evaluate the readiness of emergency departments for a disaster situation. A hybrid model called the “analytic decision‐making preference model” based on analytic hierarchy process, decision‐making trial and evaluation laboratory, and technique for order of preference by similarity to ideal solution methods is proposed. Analytic hierarchy process is used to determine the criteria and subcriteria weights. Then, decision‐making trial and evaluation laboratory is used to evaluate interdependence between criteria and subcriteria. After this, technique for order of preference by similarity to ideal solution is applied to rank the emergency departments from highest to lowest according to their closeness coefficient. A real‐life application in Colombia is presented.  相似文献

With 21,000 people annually killed in road traffic (estimated figure by World Health Organization), Bangladesh has one of the highest fatality rates in the world. Vulnerable road users (VRUs) account for over 50% of road traffic casualties, and 70% of casualties occur in rural areas. As in many Low and Middle Income Countries (LMICs), the official road accident statistics are incomplete and biased.Safe Crossings (Netherlands) and the Centre for Injury Prevention and Research Bangladesh (CIPRB) (Bangladesh) received permission from the Bangladesh government in 2014 to design and implement an integrated speed management program (consisting of a combination of small-scale infrastructural measures, active community involvement and road user education) at three locations where a national highway intersects small communities. The infrastructural countermeasures to improve road safety consisted of speed humps, rumble strips, signs and road markings and were designed following the Dutch road design guidelines. In a Before–After study design, we used a combination of three research methods to monitor and evaluate the road safety interventions. We created our own traffic accident recording system with trained local record keepers, we conducted laser-gun speed measurements of motorized traffic (both at intervention and control locations), and we applied the Dutch Objective Conflict Technique for Operation and Research (DOCTOR) for observing serious traffic conflicts at the intervention locations. The latter was based upon DOCTOR scores from video recordings of the behaviour at the three experimental locations Before and After the interventions.Prior to installing the intervention program, the three locations combined had, on average, about 100 serious accidents, 10 deaths, and 200 injured people on a yearly basis. In April 2015, all infrastructural measures were completed. In the after period (till the end of January 2016), the alternative accident recording system showed a 66% reduction in the number of serious accidents, a 73% reduction in the number of injured people, and a 67% reduction in the number of people killed.The unobtrusive laser-gun speed measurements resulted in a net reduction of 13.3 km/h (or 20% in relative terms) on average at the intervention locations by taking the general speed development at the control locations into account. According to Nilsson’s power law this would result in a 59% reduction of the number of people killed, well in line with the actual accident figures.The total number of serious conflicts (only DOCTOR scores 3, 4, and 5) was significantly reduced from 64 serious conflicts per location in a 4.5 h period Before to 29 serious conflicts in the After period, on average (Poisson distributed variable, p < 0.01), or a 55% reduction in relative terms. By including the traffic volumes, the reduction in conflict risk overall is 54%. Moreover, the severity of conflicts was reduced in the After period with only one most severe conflict (DOCTOR score 5) left. Buses represent the largest portion of road users involved in serious conflicts at all three locations, followed by cars and CNGs (Compressed Natural Gas vehicle). By far, the most frequently occurring conflict is of the type head-on conflict between an overtaking bus or car that is encountering a road user in opposite direction (for the greater part a CNG).All three evaluation measures point to a similar impact of the intervention program and unveil an improvement in road safety between 54% and 60%. The speed-reducing measures indeed considerably reduce the speed of motorized traffic, both the mean speed and 85th percentile values, both the number and severity of serious conflicts are reduced, and the actual number of accidents has decreased. It appears that Nilsson’s power law for the relation between a difference in mean speed and the change in the number of accidents also applies to LMICs.Speed management measures as common in high-income countries appear to be also effective in LMICs. For evaluation purposes of road safety impacts, a Traffic Conflicts Technique approach (also developed in high-income countries) seems valid and effective as well for application in LMICs.As there are thousands of traffic black spots with similar characteristics as the three intervention locations in Bangladesh, this integrated approach may well offer similar road safety improvements elsewhere.  相似文献

The objective of the study was to assess the relationship between conflict management styles and work-related well-being of employees in a higher education institution in South Africa. Participants were academic personnel (n = 180) and support staff (n = 201), of which 59.9% were females and 29.9% were black African participants of a large South African university. They completed self-report measures of conflict management and work-related well-being. The data were analysed to predict work-related well-being from conflict management styles and to determine the differences between support staff and academic personnel regarding conflict management styles and work-related well-being. Findings indicated the conflict management style of compromise to predict lower levels of engagement and higher levels of disengagement. Support staff reported to utilise the compromising and dominating style more than did academic personnel. Diversity in conflict management styles may serve organisations better than a monolithic conflict management style.  相似文献

When faced with threats of violence, it is of great importance to assess the risk for actual harm to occur. Over the last decades, this task has developed into a domain of its own and professionals have specialised in threat assessment . However, it is yet unknown whether professional experience affects the quality of threat assessments. The present study examined how threat assessment professionals (N  = 44), university students (N  = 44), and laypersons (N  = 45) assessed the risk for violence in three fictitious cases. The assessments (i.e., assigning risk values to different pieces of information) were found to be strikingly similar across the three groups. Yet, professionals agreed more with one another on their assessments, and professionals identified more relevant (empirically supported) threat cues when given the opportunity to request additional information. These results suggest that threat assessment professionals know better than nonprofessionals what information to look for, and hence, they may contribute most in the process of gathering information to clarify the threat. Such knowledge can help to optimise the use of expertise, which may improve the quality of threat assessments. The current findings can be of value to those who consult threat assessment professionals, as well as to the professionals themselves.  相似文献

女性员工性别身份印象管理是指女性员工为了扭转他人对自己女性身份的偏见和消极印象,而影响他人看法的过程。性别身份印象管理策略包括社会再范畴化策略和积极区分策略,前者旨在减少与女性身份的联系,后者意在强调女性身份的积极意义。两类策略会对女性获得的评价、职业发展和个人福祉产生不同的效果;工作场所偏好、性别刻板印象强弱等因素调节了这两类策略的效果。未来研究应继续从性别身份印象管理、组织干预和中国文化背景等方面探讨如何减少性别歧视对女性员工的影响。  相似文献

This article theoretically discusses Arlie Hochschild's (1983, 1998) concept of the ‘real’ and ‘false’ self (1983: 194) and how this holds together her model about how it is we manage our emotions. Hochschild draws on ideas about surface acting, deep acting and authenticity to support her theory of emotion management. In this discussion I argue that these ideas undermine the clarity of the theoretical model Hochschild tries to develop to explain emotion management. The first aim here is to demonstrate that this concept of the real and false self acts as an unnecessary conceptual linchpin making Hochschild's ideas about emotion management opaque. The second aim in this article is to theoretically engage with Pierre Bourdieu's (1984, 1990) concept of habitus as a way of overcoming Hochschild's idea of the real and false self.  相似文献

死亡提醒效应是指个体在死亡提醒后会产生世界观防御或自尊寻求的一种普遍现象。其心理机制是以死亡想法通达性为指标的潜在死亡焦虑,影响因素则包括年龄、宗教信仰、结构需求、自我控制、依恋类型等个体差异和不同的情境启动。未来研究应解释与死亡无直接关联的刺激可引发类似效应的原因,进一步阐释与证实潜在的死亡焦虑,并明确自尊对死亡提醒效应的影响。  相似文献

The present study examined babies as death anxiety buffers with Chinese participants in three experiments. In Experiment 1, death-related thoughts increased college-aged participants' interest in human babies. In Experiment 2, images of newborn animals reduced the number of death-related thoughts recorded by college-aged participants. In Experiment 3, female factory workers who read news articles describing deaths of babies had pessimistic estimations of their own life expectancies. An explanation of these results is provided within a terror management theory framework, with a primary focus on how babies reinforce cultural worldviews and enhance self-esteem via the notion of symbolic immortality. Thus, the anxiety-buffering function of baby is subsumed under cultural worldviews validation and self-esteem enhancement.  相似文献

This article is about a case of successful introduction of a technological change in a police department. It presents the links observed between the approach used to manage the transition and the perception that end-users reported regarding their stress, their health condition, and their efficiency at work. End-users of the new system reported a high level of satisfaction towards the method used, with few problems related to their stress, their health condition, and their global efficiency. People who reported such problems also reported more problems integrating the change. Close guidance provided to workers at field level and active support to enhance a fast mastering of the new skills seem to have played a major role.  相似文献

大学生时间管理倾向对其社会适应能力的影响   总被引:4,自引:0,他引:4  
该研究对180名大学生的时间管理倾向及其社会适应能力的关系进行探讨。结果发现,被试的时间管理倾向及其3个维度(时间价值感、时间监控观、时间效能感),以及社会适应能力在性别、学科等因素上没有显著差异;时间管理倾向高分组和低分组被试在社会适应能力上有极其显著的差异。将社会适应能力对时间管理倾向3个维度进行逐步回归分析,结果表明,时间效能感对社会适应能力有好的预见性。因此,开展卓有成效的时间管理训练可以作为提高大学生社会适应能力的一种方法。  相似文献
