This study investigated a multi-mediation model of the relationship between bullying behavior, peer victimization, personal
identity, and family characteristics to adolescent depressive symptoms in 194 high school students, 12–18 years of age. In
the first model, peer victimization mediated the relation between bullying behavior and depressive symptoms. In the second
model, personal identity mediated the relation between peer victimization and depressive symptoms. In the final model, the
two mediation models were combined. The relative influence of family characteristics on all variables in the two mediation
models was studied using structural equation modeling. The results supported both mediation models and confirmed the influence
of family characteristics on all variables in the mediation models. This study indicates that victimization by one’s peers
has consequences for adolescents’ psychological health when their personal identity is affected. In addition, the study was
able to model several processes in which family characteristics were related to adolescent depressive symptoms. Moreover,
the final combined model (in which the two mediation models and the influence of family characteristics on all variables were
confirmed) explained half of the variance in adolescent depressive symptoms.
We explore the impact of social institutions on economic performance in Jamaica through a reinterpretation of the plantation
economic model. In its original form, the plantation model fails to develop a causal link between the plantation legacy and
persistent underdevelopment. Despite its marginalization, the model remains useful for discussions on growth and development.
Consequently, we offer a reappraisal using the causal insights from Kenneth Sokoloff and Stanley Engerman. We use two examples
to demonstrate how inequality encourages the formation of institutions that are inconsistent with growth, and an empirical
analysis to confirm the hypothesized relationship between inequality, institutions, and economic development. Since inequality
is expected to influence growth indirectly, we use a structural specification, which follows William Easterly’s recent test
of Sokoloff and Engerman’s argument. Our reliance on a time-series specification is unique. We demonstrate that the expectation
that, on average, inequality and growth is negatively related and that institutions may compromise growth are accurate for
Jamaica, the most cited Caribbean nation in the current discourse. Our results carry several policy implications, including
support for the recent calls in Jamaica for political restructuring. However, both the paucity of similar studies and the
importance of the implications for sustainable growth and development demand further analyses.

A review of recent quantitative studies on the International Monetary Fund reveals that much of the conventional wisdom is
incorrect. Recent studies have demonstrated a new degree of methodological rigor, have drawn more heavily upon insights from
political science, and have asked a number of new questions. We review studies of participation in IMF programs, design of
IMF conditionality, implementation and enforcement of IMF conditions, conventional program effects and catalytic effects.
At every stage, we find substantial evidence of the influence of major IMF shareholders, of the Fund’s own organizational
imperatives, and of domestic politics within borrowing countries. We conclude that very little is known with certainty about
the effects of IMF lending, but that a great deal has been learned about the mechanics of IMF programs that will have to be
taken into account in order to obtain unbiased estimates of those effects.
In 2005 Indonesian and European institutes joined to start the first step for the implementation of an Ocean Operational System
in the Indonesian archipelago. The system will support the decision making process for the sustainable use of marine resources,
providing useful information and added value products as well as a service for an improved management of the sea with high
business impact to targeted groups as public authorities and commercial operators (coastal managers, fishermen, shipping companies).
In this paper the System is shortly described with its potential benefits and economic and social impacts.
We investigate the role of Congress in the growth of federal public expenditure since 1930, building on the work of Kau and Rubin (Public Choice, 113:389–402, 2002). The model incorporates majority party strength and the extent of party control of Congress in addition to the median ideological position of elected representatives. We first provide estimates of the relative importance of the state of Congress and of trending supply and demand-side economic factors in the evolution of federal spending. The resulting models are then used to simulate the consequences of the radical and historically unprecedented shift to the right of Congress in 1994/95. 相似文献
This paper investigates China's economic growth potentials and limitation up to 2020 and recommends a trend of economic regionalization. A sustainable growing economy is a necessity for China's future stability. The growth sustainability of the Chinese economy depends essentially on its continued commitments to institutional reform and economic deregulation. China's relaxation of government intervention in economic activities has led and will be leading China to decentralize its central governmental authority over economic planning and control. This will consequently stimulate the emergence of regional economies in Mainland China. In the next two decades, there will likely be 10 regional economies with relatively independent industrial structures emerging in Greater China (or the Chinese Economic Area of Hong Kong, Macao, Taiwan and the Mainland) as a result of economic liberalization and decentralization. 相似文献
Interpreting a myocardial inflammation as causal, contributory or as of no significance at all in the cause of death can be challenging, especially in cases where other pathologic and/or medico-legal findings are also present. To further evaluate the significance of myocardial inflammation as a cause of death we performed a retrospective cohort study of forensic and clinical autopsy cases. We revised the spectrum of histological inflammatory parameters in the myocardium of 79 adult autopsy cases and related these to the reported cause of death. Myocardial slides were reviewed for the distribution and intensity of inflammatory cell infiltrations, the predominant inflammatory cell type, and the presence of inflammation-associated myocyte injury, fibrosis, edema and hemorrhage. Next, the cases were divided over three groups, based on the reported cause of death. Group 1 (n = 27) consisted of all individuals with an obvious unnatural cause of death. Group 2 (n = 29) included all individuals in which myocarditis was interpreted to be one out of more possible causes of death. Group 3 (n = 23) consisted of all individuals in which myocarditis was reported to be the only significant finding at autopsy, and no other cause of death was found. Systematic application of our histological parameters showed that only a diffuse increase of inflammatory cells could discriminate between an incidental presence of inflammation (Group 1) or a potentially significant one (Groups 2 and 3). No other histological parameter showed significant differences between the groups. Our results suggest that generally used histological parameters are often insufficient to differentiate an incidental myocarditis from a (potentially) significant one. 相似文献
