As a consequence of a concatenation of external and internal events, the economy of the Democratic Republic of the Congo (DRC) has informalized to an unprecedented level over the last few decades. A comparison of budget surveys carried out in 1975 and 2004 respectively allows us to ascertain the effect of this process on income inequality and poverty in Kinshasa. We find that the extent of inequality in the capital city of the DRC has remained largely unchanged, which strongly suggests that informalization has been a viable survival strategy for those at the lower-income end of society. Unexpectedly, whereas distinctions such as gender and age lost much of their profiling power in the period considered, other cleavages such as education and geography, which may be assumed to be much more intimately related to the formal sector, continued to play an important role in structuring inequality in Kinshasa’s deeply informalized economy.  相似文献

The paper presents lifetime and six-month prevalence of substance use by 1st, 4th, and 7th graders (N=2573). Smoking and alcohol consumption was surprisingly high even for 1st graders. The use of developmentally more advanced substances, such as marijuana, was associated with the use of substances that typically emerge earlier, such as beer. Significantly more of the multiple substance users in the 1st and 4th grade were already engaged in a variety of conduct problems and delinquent acts than were either single users or nonusers. The findings show that substance use, even at Grades 1 and 4, is an indicator of boys who commit a wide variety of problem behaviors. For the 7th graders, the use of marijuana was especially associated with the commission of more serious delinquent acts. Multiple substance use reported by the 7th graders also signified a higher frequency and volume of use. The results of the study are related to a developmental conceptualization of conduct problems, delinquency and substance use.Research interests: antisocial behavior and substance use.Research interests: the development of antisocial behavior and substance use; familial processes leading to deviant behavior; the prediction of delinquency.Research interests: development of concealing antisocial behaviors and processes that affect such development.  相似文献

The fundamental developmental hypothesis of the identity status model is that as adolescents become older they undergo progressive developmental shifts in identity status: from diffusion to foreclosure or moratorium, from foreclosure to moratorium, and from moratorium to identity achievement. In Study I we give an overview of identity status studies carried out during the period 1966–1993 and show that progressive developmental trends (PDTs) are found in most of these studies. However, they usually involve progressive developmental trends in one of the higher or lower statuses (PDT 1), while only a small minority involve systematic progressive developmental trends, i.e., in at least three statuses (PDT3). It is easier to show progressive developmental trends with separate measures for commitment and exploration than with identity status classification. Study II reports on our own research into relational identity, measured with a new instrument: the Utrecht-Groningen Identity Development Scale (U-GIDS). Application of the U-GIDS allows the construction of four statuses: diffusion, moratorium, closed commitment and achieving commitment. For these four statuses progressive developmental trends were found for relational identity in both one of the higher and one of the lower statuses. The four statuses of our model display exactly the same connection with psychological well-being as the statuses of Marcia's model. The high commitment statuses show the highest level of psychological well-being, followed by the diffusions, while the moratoriums are the least happy. This result offers a new perspective on moratorium as a high identity status. Finally it was found that the differences in psychological well-being among the statuses become greater as adolescents become older.This research was supported by a grant from the Dutch Organization for Scientific Research (NWO) to the Utrecht Study on Adolescent Development (USAD) 1991–1997.Research interests include personality and social development in adolescence.  相似文献

This paper shows that political institutions matter in explaining defaults on external and domestic debt obligations. We explore a large number of political and macroeconomic variables using a non-parametric technique to predict safety from default. The advantage of this technique is that it is able to identify patterns in the data that are not captured in standard probit analysis. We find that political factors matter, and do so in different ways for democratic and non-democratic regimes, and for domestic and external debt. In democracies, a parliamentary system or sufficient checks and balances almost guarantee the absence of default on external debt when economic fundamentals or liquidity are sufficiently strong. In dictatorships, high stability and tenure play a similar role for default on domestic debt.  相似文献

This paper contends that copyright is a product of the invention of print. Before that time, writings were seen as part of the common heritage of humanity and if someone copied a book by hand they deserved the right to own the copy. The digitalization of not only print, but also intellectual products such as music, graphics and video has caused problems more deep-seated than many copyright lawyers would admit to. In fact, a paradigm shift has occurred with information at the core. The older paradigm comes from the world of Descartes and Newton and focuses on material things. The legal system of that era correspondingly focused on material things, making it impossible to own, possess or have any other real right in incorporeals. To cover intellectual property a special subsystem of law was designed which is now starting to show the strain. It is argued that information ages quickly and by over-protecting it one loses the value of the asset. Power and wealth will come from transmitting and adding value to information. In this regard personal rights might be more valuable than real or intellectual property rights, unless the latter adapts to change more rapidly.  相似文献

As part of a larger study of probation workload and workforce challenges in one southeastern state, this study reports the results from a statewide survey of probation officers’ experiences supervising probationers with mental illness. A total of 615 officers responded to closed- and open-ended questions about the challenges and barriers to supervising offenders with mental illness, and the responses of officers from rural versus urban settings were compared. Officers reported that probationers with mental illness are difficult to supervise and supervision challenges are exacerbated by a scarcity of mental health and substance abuse treatment resources, limited social support, and a lack of employment opportunities for this population of probationers. Officers report unique and similar challenges across rural and urban settings. This study contributes to our understanding of the challenges of supervising probationers with mental illness and informs practice, policy and research at the interface of the criminal justice and mental health systems.  相似文献

Social research that informs the implementation of natural resource policies is frequently driven by the logic of the policy system itself. A prevailing concern with achieving policy outcomes can lead, however, to lack of attention to equally important aspects, for example the challenges the policy instruments present to those they are targeting and the consequences this might have for government–citizen relationships. To help guide research into these issues we have developed a situational–interactional approach to interpretive policy analysis that seeks to examine the processes involved when people collectively make sense of government instruments. The theoretical basis is provided to a large extent by Luhmann’s theory of self-referential social systems. In addition, we operationalise the concepts of interactional framing and resemiotisation to capture the active work of the citizens in sense-making processes. We then apply our situational–interactional analysis to small-scale forest ownership in Flanders. Analysis of data from focus groups with forest owners reveals how interactions build on each other in the co-development of particular strategies to cope with government intervention. Finally, we discuss two future directions for research. First, the forest owners find themselves in an inescapable relationship with the government, and feel their autonomy is threatened. Government intervention, therefore, will almost necessarily lead to resistance. Second, forest groups enhance compatibility between the government system and the forest owners, but rather than narrowing the gap between the two worlds they tend to emphasise it.  相似文献
