The recent catastrophic explosion in Beirut highlights how the safe handling and storage of solid ammonium nitrate (AN) is of paramount importance. This article discusses the explosion hazard of solid AN from a fundamental and historical perspective and focuses on the main mechanisms that contributed to past events, including fire, contamination, product degradation, and shock. Critical loss prevention recommendations are summarized, referencing the recent major update to FM Global Loss Prevention Data Sheet 7-89 from January 2021. Last, a method to predict the explosive yield for explosions of solid AN in storage is presented. 相似文献

Drawing on systems theory, we conducted a moderated meta‐analysis of the training and organisational performance relationship using 119 primary studies. We examined the moderating effects of quality versus quantity of training, time, institutional and organisational context factors in the relationship between training and organisational performance. Our findings reveal that training is positively and directly related to organisational performance with no statistically significant difference between measures of training quality and quantity. We found that the relationship was stronger over time and that country performance orientation and country labour cost moderate the training and organisational performance relationship. We found no evidence for the moderating effects of the three organisational context moderators we examined (i.e. industry sector, organisational size and technology intensity). Finally, our results reveal that training type (i.e. general or firm‐specific) does not moderate the training and organisational performance relationship. 相似文献

We examine the influence of firm ownership composition on both the abnormal returns at the announcement of a stock split and liquidity changes following a stock split. We find three results. First, the largest post‐split increase in institutional ownership occurs for firms that had low institutional ownership before the split. Second, changes in liquidity are negatively related to the level of institutional ownership before the split. Last, the abnormal return following a split is negatively related to the level of institutional ownership before the split. These findings are important as they shed new light on the source of stock split announcement returns. 相似文献

The global property boom of the 1980s and its aftermath has prompted considerable debate among academics. For the most part research has been directed toward the global cities of London, New York and Tokyo. Notwithstanding the significance of property processes within these global cities, metropolitan areas outside of the core financial centres have also experienced major transformations in their property markets. This paper examines the character of Auckland's speculative office property boom of the 1980s which resulted in a level of output comparable to global cities such as Paris and Frankfurt. We argue that the wholesale reregulation of the New Zealand economy in the 1980s, and in particular the liberalization of financial markets and the share market, provided a context in which the structure of agents associated with the provision of office space was radically altered. The rise of property companies, and their dominance of the development process throughout the boom and subsequent crash, is detailed. Whilst Auckland's property boom conforms to the global experience, we argue that the specific character and intensity of the development process in Auckland highlights the need to appreciate the ‘particularity of place’. 相似文献
