Abstract

This paper analyses work, childcare, and earnings of mothers in the slums of Guatemala City and Accra. Similar factors affect decisions to work and to use formal daycare, but the importance of childcare varies with the role of the formal labour sector. In Guatemala, where formal sector work is important, higher prices for informal care increase formal daycare use. However, daycare prices and proximity to daycare centers do not significantly affect earnings in Guatemala City and Accra, respectively. Providing formal daycare may be more important to mothers' decision to work in cities where formal sector work dominates.  相似文献

For all of their centralized power and undisputed authority, even crisis leaders are susceptible to breakdowns in political communication. This is particularly significant when martial rule or a state of emergency—most effective when of short duration— becomes open‐ended; the sense of urgency no longer prevails.

In the initial stage of proclaiming a constitutional emergency it is perhaps easiest to create an atmosphere of crisis and to promote a collective sense of danger. A climate of national fear and insecurity, in turn, enables the constitutional dictator to mobilize broad support even for draconian measures imposed at the expense of individual freedoms. With the prolongation of the emergency, however, and the institutionalization of crisis government, certain immunities to authoritarianism do begin to surface. As suggested by periods of prolonged emergency rule in India and South Korea, the leader becomes remote and isolated; he or she no longer feels quite so compelled to communicate; domestic opposition increases.

The experience of President Marcos and the Philippines since 1972 illustrates some of the political dynamics of the modern, permanent “emergency state.” What has happened to the New Society program of reforms should help in understanding the critical link of communication between leaders and their followers under conditions of either real or manipulative domestic political stress.  相似文献

This study revisited the Philadelphia Foot Patrol Experiment and explored the longitudinal deterrent effects of foot patrol in violent crime hot spots using Sherman's (1990) concepts of initial and residual deterrence decay as a theoretical framework. It also explored whether the displacement uncovered during the initial evaluation decayed after the experiment ended. Multilevel growth curve models revealed that beats staffed for 22 weeks had a decaying deterrent effect during the course of the experiment, whereas those staffed for 12 weeks did not. None of the beats had residual deterrence effects relative to the control areas. The displacement uncovered had decayed during the 3 months after the experiment, and it is theoretically plausible that previously displaced offenders returned to the original target areas causing inverse displacement. These results are discussed in the context of Durlauf and Nagin's (2011) recent proposal that prison sentences should be shortened, mandatory minimum statutes repealed, and the cost savings generated by these policy changes shifted into policing budgets to convey more effectively the certainty of detection. It is concluded that if Durlauf and Nagin's proposal is to succeed, then more holistic policing strategies would likely be necessary. Foot patrol as a specific policing tactic seems to fit nicely into a variety of policing paradigms, and suggestions for incorporating them to move beyond strictly enforcement‐based responses are presented.  相似文献

This pioneer work builds upon the systems of social control (synnomie) developed by Freda Adler (1983). Its intent is to assess the low crime profile of Bahrain and in so doing to offer explanations for this country's low crime rates. While there is crime in Bahrain, this country appears to be the exception to the rule that rapid industrialization breeds high crime. The unique situation in Bahrain will be analyzed by: giving an overview of the country of Bahrain, examining recent crime statistics reported by official agencies in Bahrain, the United States, and in addition, the state of Vermont. The official sources of these data are not considered to be the most reliable indicators of crime, but they are the most comparable. Vermont is used for the comparison of numbers since it has an approximate population to Bahrain.

Low statistics of the amount of crime are reported for Bahrain which form the foundation for this paper. This paper offers possible explanations of low crime by using as its base the theory of synnomie (the consistency of norm and values sharing); and summarizes the main points in this paper and draws conclusions which point in the direction for the future of Bahrain, its citizens, and incidences of reported crime as Bahrain continues with its mission of modernization.  相似文献

Pressure in the 1970's to reform the sentencing process can be attributed to a change in perceived public sentiment regarding the utility of treatment and to the belief that sentencing disparity was a severe problem in the sentencing process. Primary reform occurred in the federal judicial system with the development and implementation of rigorous sentencing guidelines. An evaluation of sentencing patterns for one federal judicial district indicates that sentencing disparity was not severe. Most federal offenders are relatively mild and consistently receive relatively mild sentences.  相似文献

During the 1970s, analyses of state and government in Western Europe were preoccupied with crises of governability and legitimacy. The early 1980s witnessed sharply differing responses to these crises, exemplified by the socialist experiment in France and Thatcherism in the UK. By the end of the 1980s, ‘governance’– in both national and European arenas – began to be regarded as the dominant institutional response to problems of governability. Considered from the perspective of comparative European government, the oft-claimed shift from government to governance appears overstated. Governance is less widespread and consequential both at national and European levels than its proponents suggest, as a survey of the propellants, conditions and national and European constellations of governance shows. Viewed historically, governance does not so much indicate a shift from government as towards government, as the core institutions of the state build up capacity to deal authoritatively and hierarchically with new governing challenges.  相似文献
