Zusammenfassung Viele l?ndliche Regionen sind mit einer Ausdehnung der Waldfl?chen konfrontiert. Dies wird
vor allem dann als problematisch empfunden, wenn die betroffenen R?ume bereits waldreich sind. Zur
Steuerung der Waldzunahmedynamik bieten sich verschiedene rechtliche Instrumente an, deren Potenziale derzeit
nicht voll ausgesch?pft werden. Weiterentwicklungsm?glichkeiten bestehen insbesondere im Hinblick
auf die Normen zur Aufforstungsgenehmigung. Hier ist ein grunds?tzlicher normativer Paradigmenwechsel
denkbar. Neureglungen k?nnten aber auch über die Einrichtung einer Experimentiergesetzgebung
zun?chst beispielhaft erprobt werden. Der Beitrag entwickelt zudem einen Leitfaden für die Beurteilung
einer “erheblichen Beeintr?chtigung des Landschaftsbilds”, einem bisher nicht ausreichend
konkretisierten Versagungsgrund für eine Aufforstungsgenehmigung. 相似文献

Recent years have witnessed growing research interest in citizen perceptions of the police. This was likely the result of the community policing movement, which sought to strengthen ties between citizens and the police, as well as to concerns about the legitimacy of the police. Most of this research focused on police agencies in the United States, and little research had been conducted on citizen perceptions of the police in Asian countries. This study sought to fill this void through an analysis of citizen perceptions of the police in South Korea. To address these issues, telephone interview survey data gathered from 11,500 randomly selected citizens were obtained in the rapidly industrializing country, South Korea. Several sets of multiple-regression models were estimated to assess the effect of urbanization, demographics, evaluations of police services, and perceived corruption on citizen satisfaction with police. The results suggested that citizens in small to mid-sized cities and large urban cities were less satisfied with police than were residents of rural areas. In addition, age, evaluations of police service, and perceptions of corruption were related to citizen satisfaction. The results were discussed in comparison to previous research in Asia and the United States and other Western countries. 相似文献

Middle‐class families face a range of challenges, including uneven income growth, imposing child care costs, and affordability gaps for higher education. The ideal policies by which policy makers and public administrators can aid the middle class are far from obvious. Policy solutions are likely to mirror our government and population, meaning that they will be decentralized and varied. Achieving a “growing and thriving middle class” requires understanding the composition of the middle class across the country. Benchmarking and measuring the middle‐class condition at the state and substate levels is critical to crafting and adopting effective policy solutions. This Viewpoint essay highlights the Colorado context to demonstrate the measurement of the middle class and tracking of its lived experiences. 相似文献

Abstract Despite many predictions to the contrary, the Republic of Korea (ROK) is currently one of the countries with most pro-American attitudes. We investigate what is behind the extraordinary resilience in US popular standing in an allegedly least likely setting. Using survey data from 2002 and 2007 and a novel methodology, Classification and Regression Tree models, we test whether US standing is: (1) a matter of interests, i.e. a reward that the USA receives because it either provides security or international public goods; or (2) whether it is a matter of image, i.e. the recognition that the USA is a role model to emulate. We find that across a large number of predictors, the Korean public mostly liked the USA because they liked American ways of doing business, which gives support to the image hypothesis. Security interests played a secondary role in shaping US standing, while the provision of international public goods had no impact in the popular assessment of the USA in the ROK. 相似文献

In February 2005, Illinois became the first U.S. state to grant home‐based child care providers (HBCPs) the right to form a labor union in order to bargain collectively with the state government. This policy inspired similar efforts across the country and represents a potentially important direction for child care policy. To date, the implications of labor unions for the cost, type, and availability of subsidized child care have not been evaluated empirically. In this study, we examine the impact of granting Illinois HBCPs the right to form a labor union on (a) the type of child care (licensed vs. license‐exempt/home‐based vs. center‐based) used by subsidy‐receiving Illinois infants and toddlers; (b) the per‐child cost of subsidized child care for infants and toddlers; and (c) the percentage of Illinois infants and toddlers who use child care subsidies. To conduct these analyses, we combine data from the Current Population Survey with Child Care and Development Fund administrative records on U.S. infants and toddlers whose families received child care subsidies during the period from 2002 to 2008. We use both a traditional difference‐in‐differences as well as a comparative case study with a “synthetic” control group approach. The synthetic control group approach improves on traditional comparative case studies by providing a transparent, empirical approach for constructing the counterfactual, documenting comparison units’ contribution to the synthetically created control group and detailing the degree to which the synthetic control group is, or is not, similar to the treated unit on preintervention measures of the outcome as well as on other selected characteristics. We find that subsidy‐receiving Illinois infants and toddlers spent an average of between 6.4 and 7 percentage points more hours in licensed care settings, as compared to license‐exempt settings, in the three years following child care unionization. We also find that between 0.7 and 1.1 percentage points fewer Illinois infants and toddlers used child care subsidies following unionization. 相似文献

This paper investigates the role that International Criminal Police Organization (INTERPOL) surveillance—the Mobile INTERPOL Network Database (MIND) and the Fixed INTERPOL Network Database (FIND)—played in the War on Terror since its inception in 2005. MIND/FIND surveillance allows countries to screen people and documents systematically at border crossings against INTERPOL databases on terrorists, fugitives, and stolen and lost travel documents. Such documents have been used in the past by terrorists to transit borders. By applying methods developed in the treatment‐effects literature, this paper establishes that countries adopting MIND/FIND experienced fewer transnational terrorist attacks than they would have had they not adopted MIND/FIND. Our estimates indicate that, on average, from 2008 to 2011, adopting and using MIND/FIND results in 0.5 fewer transnational terrorist incidents each year per 100 million people. Thus, a country like France with a population just above 64 million people in 2008 would have 0.32 fewer transnational terrorist incidents per year owing to its use of INTERPOL surveillance. This amounts to a sizeable average proportional reduction of about 30 percent. 相似文献
