This article analyzes demographic change in Bremen 1815–1914 against the background of changing employment opportunities. Within the pre-industrial employment structure, which still prevailed in the decades after 1850, in-migrants were particularly disadvantaged. When modern industries developed, the situation changed. At the beginning of the twentieth century both male and female in-migrants benefited from a higher life expectancy than the city-born population had. The strong sectoral changes in employment opportunities in Bremen at the turn of the century reinforced the trends towards family limitation. More skilled in-migrants felt the need to adapt their reproductive behavior to facilitate upward social mobility. The article argues for a wider use of archival data, like those used in their study, to explore issues relating to urban demographic change in German cities during industrialization. 相似文献

Corruption remains one of the key obstacles to democratization and good governance. Given the nature of the subject, corruption is notoriously difficult to study. International comparisons and rankings of good governance such as the World Bank World Governance Indicators, the Bertelsmann Sustainable Governance Index, or Transparency International's Global Corruption Index are very useful for providing the big picture on corruption. To understand trends and mechanisms of corruption, however, it is necessary to conduct case studies on both successful and failed cases of anti-corruption policies. This paper investigates the successes and challenges of the fight against corruption in South Korea since the beginning of democratization in 1987. The investigation shows that Korea has generally been successful in controlling corruption. The paper argues that the remaining problems can be largely explained by the legacy of authoritarian rule and the undermining of state autonomy through the concentration of economic power. 相似文献

This paper presents an ethical framework for decision-making in public administration based on the preeminent value of justice. In discussion of this framework, the paper deals with three major issues. The first of these is the character of the just administrative decision,, the second is the character of of the just public organization, and the third is the impact of a justice-based administrative ethic on the role of the responsible administrator. 相似文献

We compare several risk preference elicitation methods – including incentivised, non-incentivised, and framed methods as well as a traditional Likert survey question – in a developing country and empirically test how well consequent measures of risk attitudes predict risk taking behaviour. We find that Likert scale and non-incentivised framed survey questions are not sufficient substitutes for costlier incentivised methods in rural Niger. Instead, the incentivised framed question works best while a simplified incentivised lottery question works almost as well. More risk and ambiguity averse farmers are less likely to adopt fertiliser microdosing indicating the importance of insurance and strategies to promote learning. 相似文献
