Economic Impact of Accelerated Cleanup on Regions Surrounding the U.S. DOE's Major Nuclear Weapons Sites

The regional economic impacts of the U.S. Department of Energy's accelerated environmental cleanup plan are estimated for the major nuclear weapons sites in Colorado, Idaho, New Mexico, South Carolina, Tennessee, and Washington. The analysis shows that the impact falls heavily on the three relatively rural regions around the Savannah River (SC), Hanford (WA), and Idaho National Engineering and Environmental Laboratory (ID) sites. A less aggressive phase-down of environmental management funds and separate funds to invest in education and infrastructure in the regions helps buffer the impacts on jobs, personal income, and gross regional product. Policy options open to the federal and state and local governments are discussed.     

论洛杉矶文学先锋创作：詹姆斯·凯恩和 霍勒斯·麦科伊

凯恩和麦科伊被称作洛杉矶文学开拓先锋,他们的创作存在许多相似之处。首先,他们有着相似的城市经历。其次,他们作品中的主人公都没有归属感,都是无根之人。 他们背离自己的生命之源土地,被蛊惑来到这片精神贫瘠之地寻找希望和梦想。在这片梦幻的空间,人类基本的关系遭受了巨大的冲击以致最终崩溃。这两位作家赋予洛杉矶一种 全新的文学身份。     

Private thoughts and public actions:: A commentary on articles dealing with ethical issues in evaluation

This commentary represents a personal reaction to seven articles on ethical issues in evaluation. The author of the commentary begins with two assumptions: (1) Professional evaluators might not have the vocabulary and constructs to analyze their thoughts and actions in ethical terms, and (2) professional evaluators have often confronted troubling situations that probably contain ethical issues embedded within them. Consequently, she queries the seven articles individually and collectively in terms of the following questions: 1. What is the range of ethical problems I might encounter as an evaluator; and how do I recognize the ethical characteristics of professional dilemmas? 2. How do I describe troubling evaluation problems I have encountered that seem to have an ethical component? 3. What are some approaches I have used or might use in thinking about a proper course of action? 4. How do I know if, in a given situation, I have behaved ethically? 5. Where do we go from here?     

Understanding the etiology of child abuse: A preliminary typology of cases

This paper examines various conceptual approaches to the etiology of child abuse and reports the results of an original study. Data on 99 families with children who were court adjudicated as having suffered non-accidental trauma were analyzed by means of a cluster analysis (hierarchical nearest-neighbor clustering). Four empirically-derived clusters of family/case attributes are described and then discussed as representing separate etiologies of child abuse. The implications of this typology are also discussed as they relate to clinical practice and social policy.     

洛杉矶模式:大都市区多中心模式的经济效用分析

20世纪70年代以来,美国城市化进程中出现了新趋势,即多中心格局大都市区显著增长。洛杉矶因其独特的发展历程成为多中心大都市区的典型代表,并因其称为"洛杉矶模式"。该模式的出现对整个大都市区经济产生了积极、深刻的影响,这是以往单核式大都市区所无法达到的。

International Trade Inoperability Input-Output Model (IT-IIM): Theory and Application

The inoperability input-output model (IIM) has been used for analyzing disruptions due to man-made or natural disasters that can adversely affect the operation of economic systems or critical infrastructures. Taking economic perturbation for each sector as inputs, the IIM provides the degree of economic production impacts on all industry sectors as the outputs for the model. The current version of the IIM does not provide a separate analysis for the international trade component of the inoperability. If an important port of entry (e.g., Port of Los Angeles) is disrupted, then international trade inoperability becomes a highly relevant subject for analysis. To complement the current IIM, this article develops the International Trade-IIM (IT-IIM). The IT-IIM investigates the resulting international trade inoperability for all industry sectors resulting from disruptions to a major port of entry. Similar to traditional IIM analysis, the inoperability metrics that the IT-IIM provides can be used to prioritize economic sectors based on the losses they could potentially incur. The IT-IIM is used to analyze two types of direct perturbations: (1) the reduced capacity of ports of entry, including harbors and airports (e.g., a shutdown of any port of entry); and (2) restrictions on commercial goods that foreign countries trade with the base nation (e.g., embargo).     

Great Masters of Mexican Folk Art in Los Angeles: transnational exhibition,diasporic emplacement,and the expedient politics of display

In this essay, I trace the Great Masters of Mexican Folk Art exhibition from its inception in a privatized programme managed by the transnational bank Banamex through its multiple instantiations within U.S. museums in order to explore the transnational politics of the exhibition, as well as its role in the diasporic emplacement of Mexican Americans. In so doing, I unsettle the ways we understand the commodification of difference through museum display and argue for the re-conceptualization of the museum as a transnational space in which varied multicultural imaginaries can be engaged and mobilized.
