Suicide by crashing into a heavy vehicle: Focus on professional drivers using in-depth crash data

Objective: Road traffic suicides typically involve a passenger car driver crashing his or her vehicle into a heavy vehicle, because death is almost certain due to the large mass difference between these vehicles. For the same reason, heavy-vehicle drivers typically suffer minor injuries, if any, and have thus received little attention in the research literature. In this study, we focused on heavy-vehicle drivers who were involved as the second party in road suicides in Finland.

Methods: We analyzed 138 road suicides (2011–2016) involving a passenger car crashing into a heavy vehicle. We used in-depth road crash investigation data from the Finnish Crash Data Institute.

Results: The results showed that all but 2 crashes were head-on collisions. Almost 30% of truck drivers were injured, but only a few suffered serious injuries. More than a quarter reported sick leave following their crash. Injury insurance compensation to heavy-vehicle drivers was just above €9,000 on average. Material damage to heavy vehicles was significant, with average insurance compensation paid being €70,500. Three out of 4 truck drivers reported that drivers committing suicide acted abruptly and left them little opportunity for preventive action.

Conclusions: Suicides by crashing into heavy vehicles can have an impact on drivers’ well-being; however, it is difficult to see how heavy-vehicle drivers could avoid a suicide attempt involving their vehicle.     

Tracking managerial conflict adaptivity: Introducing a dynamic measure of adaptive conflict management in organizations

Since Darwin, adaptation to change has been associated with survival and fit. Yet, despite this, leaders and managers often get stuck in dominating approaches to conflict, and few scholars have examined the role of adaptation in managing conflicts effectively over time and across changing situations. The goal of this paper is threefold. First, we develop a new measure for assessing conflict adaptivity of managers [the Managerial Conflict Adaptivity Assessment (MCAA)], based on a situated model of conflict in social relations. We define conflict adaptivity as the capacity to respond to different conflict situations in accordance with the demands specified by the situation. The measure consists of 15 distinct work‐conflict scenarios and provides five behavioral response options, which represent five primary strategies employed in conflict. Individuals who tend to respond to the conflicts in a manner consistent with the situations provided are considered to be more adaptive. Second, we test and find that managerial conflict adaptivity is related to higher levels of satisfaction with conflict processes at work as well as higher levels of well‐being at work. Third, we test the MCAA's construct validity and provide evidence that the MCAA is positively related to behavioral flexibility and self‐efficacy. Copyright © 2014 John Wiley & Sons, Ltd.

Prediction of thermal hazards from fireballs

Various models of fireball diameter have been evaluated by statistical techniques. The model of Gayle for fireball diameter estimation showed good agreement between the predicted and experimental data. The models relating to fireball duration, transmissivity and view factor have been selected based on their relative merits. A user interactive computer program has been developed to predict thermal hazards from fireballs in chemical process industries.

On the relationship between objective increases in pay and employees' subjective reactions

This study explored whether two principles describe the relationship between the size of a pay increase (a bonus expressed as a percentage of current salary) and the attractiveness of that increase. Based on a sample of sales personnel (N = 639) and consistent with the constant proportion principle of the psychophysical law, pay increase attractiveness was unrelated to current salary level after controlling for the size of the percentage increase. In addition, at any given salary level, the relationship between the size of the increase and its attractiveness was curvilinear. The attractiveness of larger and larger bonus percentages continues to increase, but at a decreasing rate supporting the principle of diminishing returns.     

安全网试验方法的探索

安全网是一种极其普遍的特种劳动防护用品,在人们日常生产生活中应用十分广泛,尤其适用于建筑工地等高处作业.安全网对保护劳动者生命安全起着举足轻重的作用.因此,国家安监局、国家质监总局分别把该产品列为LA和QS管理产品.由于安全网质量要求至关重要,国家已制订出安全网的相关检验标准.其中安全网的耐冲击性能是安全网的一项重要物理指标,本文依据国家现行标准,对安全网的耐冲击性试验方法进行探索.     

内窥镜检查在电站锅炉内部检验中的应用

工业内窥镜是电站锅炉内部检验中不可或缺的设备,主要用来对集箱、减温器、受热面管等内部人眼无法观察到的地方进行检验,从而确定承压部件内部是否存在严重影响锅炉安全运行的缺陷.本文通过对锅炉内窥实例进行分析和总结,阐述内窥镜检查在锅炉内检中的重要性并给相关工作人员提供借鉴与参考.
