Records of all registered deaths due to injuries maintained by the Legal Medicine Department in Maputo City for the period 1 January to 31 December 2000 were reviewed. Among the 1135 registered deaths, road traffic injuries accounted for the most common underlying cause of death (43.7%), followed by firearm discharge (8.7%) and burns (7.8%). For all deaths, skull fracture (21.9%), organ system injury (17.2%) and brain tissue injury (9.3%) were the most important intermediate causes of death and among the immediate causes of death acute anaemia (21.9%) was the most common followed by asphyxia (14.4%) and traumatic shock (12.0%). Overall, most cases were seen in the age group 20-29 years (27.0%) and comprising mainly males (male/female ratio 3.1). The most commonly reported cause for the victims to sustain injuries leading to death were accidents (59.4%), followed by homicides (19.8%), unknown causes (16.1%) and suicides (4.2%). Prevention of road traffic injuries and improved emergency care and health facility-based treatment is needed to reduce injury-related mortality. 相似文献

How should we understand the relationship between urban environments and infectious diseases? This article addresses this question from three particular perspectives: that of the materialities of health, that of nature and that of networks. The first perspective analytically blends biological dynamics, environmental influence and social practice. The second perspective, mainly influenced by multispecies ethnographies, foregrounds the liveliness and unboundedness of cities. Finally, the third perspective analyses how health is drawn into the domain of security. The article argues that while globalization and urbanization are often discussed as having triggered the emergence and spread of pathogens, urban epidemics are not self‐evident and ‘natural' consequences of these pro‐cesses. They do not fall neatly into universal categories of space, modernity or risk; rather, they are produced and shaped by a range of social, political, biological and economic sites and scales. Accordingly, the emergence of pathogens depends on its articulation through specific analytical frameworks. This article suggests that a critical focus on how infectious diseases manifest themselves differently in different local contexts may not only provide insights into the manifold forms of urban life, but also into the multiple, complex and highly political constitution of health. 相似文献

We analyze the effect of worker inflows on establishments’ productivity, using German data. Previous studies for other countries have found positive effects of hiring workers from superior (more productive or higher paying) firms. Ranking establishments by their median wage, we find that inflows from inferior establishments seem to increase hiring establishments’ productivity. Further empirical analyses suggest our findings are due to a positive selection of such inflows from their sending establishments. These workers might have to find a better job match in order to advance their careers, an interpretation supported by the finding that the effect is driven by workers with short tenure at their previous employer. Our findings reflect the increasingly assortative pattern of worker mobility in Germany found in a related strand of literature. 相似文献

Recent literature (Boyd and De Nicoló, J Finance 60:1329–1343, 2005) has argued that competition in the loan market lowers bank risk by reducing the risk-taking incentives of borrowers. Using
a model where competition arises from falling switching costs for entrepreneurs, we show that the impact of loan market competition
on banks is reversed if banks can adjust their loan portfolios. The reason is that when borrowers become safer, banks want
to offset the effect on their balance sheet and switch to higher-risk lending. They even overcompensate the effect of safer
borrowers because loan market competition erodes their franchise values and thus increases their risk-taking incentives. 相似文献

It has become increasingly popular to advise investors to relocate their funds from a primarily stock portfolio to a primarily bond portfolio as they get older. However, the well-known decision rules such as mean–variance or stochastic dominance rules are unable to explain this common practice. Almost stochastic dominance (ASD) and almost mean–variance (AMV) approaches are used to examine the dominance of stock and bond portfolios. ASD and AMV rules unambiguously support the popular practice of advising higher stock to bond ratio for long investment horizons. Hence, we provide an explanation to the practitioners’ recommendation within the expected utility paradigm. 相似文献

Onshore wind energy utilisation in Germany has developed very dynamically in the last decade. This has mainly been driven
by the renewable energy laws that systematically support the expansion of renewable energy in the electricity sector. In 2009
a revised law with increased feed-in tariffs for wind energy has come into force. Existing studies already predict a wide
range of development patterns under the Renewable Energy Sources Acts 2000 and 2004. This paper investigates the long term
impact of different feed-in tariffs implemented by the legislative authorities and it provides corresponding future development
patterns of onshore wind energy utilisation in Germany. The underlying System Dynamics model considers technical as well as
economic conditions and constraints. The approach and the model’s results are contrasted with other published predictions
qualitatively and quantitatively. This comparison shows that the model’s outcome lies in the range of predictions by existing
studies, but also shows some interesting differences.
Zusammenfassung Die Entwicklung der Windenergienutzung in Deutschland wahrend der letzten Dekade verlief sehr dynamisch. MagBgeblich dafur war die systematische Forde-rung mittels der Erneuerbare Energien Gesetze (EEG) bzw. deren Vorlaufer. Vom Jahr 2009 an gilt ein uberarbeitetes Gesetz, welches u.a. erhohte Einspeisever-gutungen furWindenergie beinhaltet.Vorliegende Studien, die sich mit derzu-kunftigen Entwicklung auseinandersetzten, zeigen bereits deutlich unterschied-liche Szenarien fur die Entwicklung unter dem EEG 2000 und 2004. Diese Arbeit setzt sich mit den langfristigen Auswirkungen der verschiedenen vom Gesetz-geber festgelegten Einspeisetarife auseinander und stellt entsprechend unter-schiedliche Ausbauszenarien fur die deutsche Onshore Windenergienutzung dar. Das zugrunde liegende System Dynamics Modell berucksichtigt dabei sowohl technische als auch okonomische Parameter. Der Ansatz sowie die Ergebnisse werden anderen veroffentlichten Prognosen gegenubergestellt. Die Ergebnisse liegen innerhalb der Spannbreite der anderen berucksichtigten Studien, zei-gen jedoch auch interessante Unterschiede.相似文献

Modality analysis is a text analysis methodology that affords comparisons of how people from distinct cultural contexts differ
in their accounts of why one or more of their numbers find specific activities possible, impossible, inevitable, or contingent.
The technique is built around a two-part semantic grammar, the application of which involves the identification of modal clauses
in texts, the classification of these clauses according to their modal forms, and the identification of rationales associated
with the clauses’ modalities. We show that with sufficient training the method affords high interrater agreement. After providing
a few tips on data-collection strategies, results are presented from a modality analysis of editorials sampled from the Arab
newspaper, Al Riyadh, and the Hindi newspaper, Hindustan. The analysis illustrates how modal expressions can be used in locating well-known (e.g., Islamic and Hindu) cultural characteristics
from among the vast quantities of discourse that societies continuously generate. 相似文献

This paper introduces optimal matching analysis (OMA) to the field of top management research. With this method, we develop six career patterns of top management team (TMT) members from five countries based on their international experience, organizational tenure and professional experience. The results provide strong support for the significance of these patterns, since each country (Denmark, Germany, Japan, the United Kingdom and the United States) shows one to four predominant career patterns of their managers and the occurrence of these patterns also differs significantly between the fields of activity within the TMT (chairperson, head of a division, primary activities and support activities). 相似文献
