Every day 25,000 people die of hunger and hunger-related causes. While it is recognised that the international development system is not as effective as it should be, years of endeavours to achieve greater harmonisation of international aid and to create an effective architecture pass by without adequate results. The article introduces a framework for enhancing the effectiveness of the international development system, based on fundamental concepts of Systems Thinking. It discusses the complex systemic challenges to development and suggests that more effective control is a key precondition for greater effectiveness in development as a whole.  相似文献

Zusammenfassung Durch Urteil vom 10. Januar 2006 hat der Europ?ische Gerichtshof die Umsetzung der Vogelschutz-Richtlinie (V-RL) und der FFH-Richtlinie (FFH-RL) beanstandet, insbesondere der Projektbegriff der FFH-Vertr?glichkeitsprüfung sowie bestimmte Freistellungen von den artenschutzrechtlichen Verboten wurden als europarechtswidrig verworfen. Die Korrektur dieser M?ngel ist durch die sog. kleine Novelle des Bundesnaturschutzgesetzes erfolgt. Nachfolgend werden die ?nderungen des Artenschutzrechts sowie die Auswirkungen der Aufhebung des Projektbegriffs vorgestellt.  相似文献

Abstract: The mass media are assigned an important role in political campaigns on popular votes. This article asks how the press communicates political issues to citizens during referendum campaigns, and whether some minimal criteria for successful public deliberation are met. The press coverage of all 24 ballot votes on welfare state issues from 1995 to 2004 in Switzerland is examined, distinguishing seven criteria to judge how news coverage compares to idealized notions of the media’s role in the democratic process: coverage intensity, time for public deliberation, balance in media coverage, source independence and inclusiveness, substantive coverage, and spatial homogeneity. The results of our quantitative analysis suggest that the press does fulfil these normative requirements to a reasonable extent and that fears about biased or deceitful media treatment of ballot issues are not well‐founded. However, some potential for optimizing the coverage of referendum campaigns by the Swiss press does exist.  相似文献

Fully participatory jury deliberations figure prominently in the idealized view of the American jury system, where balanced participation among diverse jurors leads to more accurate fact‐finding and instills public confidence in the legal system. However, research more than 50 years ago indicated that jury‐room interactions are shaped by social status, with upper‐class men participating more than their lower‐class and female counterparts. The effects of social status on juror participation have been examined only sporadically since then, and rarely with actual jurors. We utilize data from 2,189 criminal jurors serving on 302 juries in four jurisdictions to consider whether—and in what conditions—participation in jury deliberations differs across social groups. Our results indicate the continuing importance of social status in structuring jury‐room interactions, but also reveal some surprising patterns with respect to race and gender that depart from earlier research. We also find that contextual factors including location, case characteristics, and faction size shape the relationship between social status and participation. We conclude with a critical discussion of our results and urge other researchers to take into account contextual factors when examining how individual juror characteristics shape what happens inside the jury room.  相似文献

Urban regeneration companies (URCs) are public‐private entities appearing across Europe. They are created specifically to manage and implement more effectively urban regeneration projects. Core ideas behind the establishment of these newly emerging partnerships aim to tackle the challenging process of restructuring these organizations so as to function at arm’s length from political oversight. However, contemporary literature on governance suggests that organizational form may be less a factor than managerial capability. Using survey data obtained from individuals who are heavily involved in Dutch urban regeneration partnerships, this article points out why twin URC organizational characteristics, i.e., functioning at arm’s length from politics plus its tight organizational format, are not significant to their effective performance. Instead, use of multiple management strategies is ultimately more relevant to their effective performance.  相似文献

Electronic control devices (ECDs) deliver high‐voltage, low‐current energy pulses temporarily paralyzing a person. For the ECD–human interaction, we have developed a computer model using the SEMCAD program within which to simulate the electrical effects throughout the body resulting from the imposition of an ECD pulse at a particular point on the body surface. Our human body models were based on cross‐sectional MRIs and CT scans, with the dielectric properties of the various tissues assigned based on previously published values. We simulated the application of a single ECD pulse and calculated the resulting electric field strength and current and charge densities at different body locations. The results were compared with corresponding values obtained by other researchers in similar simulations. Furthermore, we simulated an application of a pulse of 20‐millisecond duration equal to the European household current of 50 Hz and to the ventricular fibrillation threshold. The resulting current level indicated at the heart muscle was 1/5 the level considered the threshold for triggering ventricular fibrillation.  相似文献
