How to Sociologically Read a Movie

Movies embody cultural values; those of class, gender, ethnicity, region, and nation come immediately to mind. They also reflect deeper civilizational assumptions such as Enlightenment values of moral redemption through human agency toward social progress that will be examined here by comparing the movies Avatar (2009) and District 9 (2009). The methodology is to identify backstage cultural assumptions that have to be assumed to make sense out of frontstage plot development. The idea of “species jumping” is introduced to illustrate the deteriorating idea that distinctly human agency is capable of producing a better social world and attaining secular moral redemption as the protagonists in both films reincarnate into alien species.     

Turnover‐induced Forgetting and its Impact on Productivity

In this paper we investigate organizational forgetting, the notion that a firm's knowledge does not persist over time, exploring knowledge depreciation caused by changes in human capital. We first conduct an in‐depth exploratory case study to identify organizational forgetting. The empirical evidence suggests that organizational forgetting occurs when abrupt personnel turnover takes place. The data reveal a forgetting pattern that is entirely episodic in nature. Thereupon we conduct a confirmatory piece, using multiple regression models, to measure the impact of organizational forgetting on overall productivity. We find that, as a result of repeated forgetting processes, productivity falls in spite of continued output accumulation because of changes in the characteristics of the resource where experience resides.     

Democracy Cannot Survive Overpopulation

This article addresses increasing concerns about the decline of democracy at all levels of government. It is shown that overpopulation and technology are major causes of this decline. It would be unwise to try to stop the development of technology; therefore it is urgent that we move quickly to address the problems of overpopulation.     

Diabetes, aging and physical activity

Diabetes mellitus (DM) is a metabolic disease affecting the regulation of insulin and glucose causing a disruption in the normal control of counterregulatory hormones and macronutrients, resulting in blood glucose accumulation. Metabolic deregulation leads to the production of noxious substances that have a particular propensity for damaging vascular and nervous structures. Physiological changes observed with aging are correlated with a concomitant increase in DM and its associated complications. Long-term complications, including peripheral and central neuropathies, micro- and macrovascular damage, retinopathy, and nephropathy are the major causes of mortality in diabetics [cardiovascular disease (CVD) being the primary complication causing death in this population]. All-cause mortality is three to four times greater in the DM population; hence, management of DM is of timely importance, particularly with a projected prevalence increase of 134% within the next 25 years among individuals over the age of 65 years. Exercise modalities, including endurance and resistance training, were employed to improve glycemic/metabolic control and to ameliorate the progression of DM-related complications. Several risk factors, including glucose levels, blood pressure, lipid/cholesterol profile, and BMI, are reportedly improved with these modes of exercise. However, not all studies demonstrate an improvement in risk factors, but consistently note improvement in complications and a reduction of DM incidence. There is convincing evidence that exercise, with or without specific improvements to traditional DM-related risk factors, is an effective therapy for the management of DM.The Canadian Centre for Activity and Aging is affiliated with St. Joseph’s Health Care and The University of Western Ontario, London, Ontario, Canada.     

Empirical bayes estimation in contingency tables

In the estimation of cell probabilities from a two–way contingency table, suppose that a priori the classification variables are believed independent. New empirical Bayes and Bayes estimators are proposed which shrink the observed proportions towards classical estimates under the model of independence. The estimators, based on a Dirichlet mixture class of priors, compare favorably to an estimator of Laird (1978) that is based on a normal prior on terms of a log–linear model. The methods are generalized to three–way tables.     

Citizenship Status and TANF Exits: A Proportional Hazard Model

ABSTRACT

This study compared exits between citizen and noncitizen heads of household from the Temporary Assistance to Needy Families (TANF) program. With longitudinal monthly administrative data and a Cox proportional hazard model, the study examined how the economy and recipients’ personal characteristics affected their exits. The sample consisted of 28,308 families headed by citizens and 2,547 families headed by a noncitizen on TANF. Key findings reveal that families on TANF exit the rolls primarily during the first 8 months after entrance. Results showed that families headed by a noncitizen remain on TANF longer than families headed by a citizen. The roles of minimum wage and unemployment in shaping the risk of exit for noncitizen compared to citizen families were explored. Suggestions for further research and how to serve recipients best in times of economic downturns are provided. Similar research needs to be conducted in states where temporary TANF time limits do not exist.     

中国环境与规划（二）

中国人常说：“良药苦口，忠言逆耳”。在中国做了10年规划，我看到了一些不是简单的问题。有些问题不知道是否应该说出来，但是如果不说出来，我认为有愧领导的爱护。有一次，我与好朋友前纽约环境保护局局长、世界上一流的水处理专家ALAPPLETON交谈这些问题。没想到，他与我有许多共同的看法。后来。我告诉他我正在写一本有关对中国规划建议的书，不如他来个“友情演出”，替我写—篇我们对环境保护共同看法的文章。为了得到更多“外脑”的意见和支持，我要求编辑必须将原文登出。     

Labor Union Political Strategy in an Era of Decline and Revitalization

U.S. labor unions faced sharp membership losses over the last few decades, and some responded by ushering in a new, revitalized model of organizing. Yet we know little about how these forces may be shaping the political activities of the labor movement. Has crisis prompted unions to take aim at public policies inhibiting union vitality, or have unions turned outward to embrace broader social causes? This paper uses an original dataset of union appearances in congressional hearings to analyze unions’ legislative advocacy activities. Findings suggest substantial differences between those unions that are likely to appear in hearings on core labor‐related topics and those that appear in hearings on broad social issues: AFL‐CIO unions are more likely to participate in hearings on core labor issues, while unions commonly cited as “revitalized” and public sector unions are more likely to appear in hearings on broad social issues.     

Interpersonal Amplification of Risk? Citizen Discussions and Their Impact on Perceptions of Risks and Benefits of a Biological Research Facility

Much risk communication research has demonstrated how mass media can influence individual risk perceptions, but lacks a comprehensive conceptual understanding of another key channel of communication: interpersonal discussion. Using the social amplification of risk as a theoretical framework, we consider the potential for discussions to function as amplification stations. We explore this possibility using data from a public opinion survey of residents living in potential locations for a new biological research facility in the United States. Controlling for a variety of key information variables, our results show that two dimensions of discussion—frequency and valence—have impacts on residents’ perceptions of the facility's benefits and its risks. We also explore the possibility that an individual's overall attitude moderates the effect of discussion on their perceptions of risks and benefits. Our results demonstrate the potential for discussions to operate as amplifiers or attenuators of perceptions of both risks and benefits.     

Drug Use Among Latino Youth: Two Popular Criminological Perspectives Infused with Latino Culture

Drug use among Latino youth in the United States is a persistent problem which has been examined from a variety of academic disciplines, including psychology, sociology, and social work. These share significant overlap with mainstream criminological approaches to explaining delinquency and drug use, which have virtually ignored these issues or investigated them exclusively from an ethnocentric perspective. The naturally multidisciplinary topics of Latino youth, culture, and drug use can be readily situated within two popular frameworks (social control and strain), and these can also be enriched with core aspects of Latino culture. Complimentary cultural values enhance these two perspectives and significantly contribute to our criminological understanding of some of the reasons why Latino youth become involved in drug use. After reviewing our current knowledge on this subject, suggestions are made for ways future criminological research can more deeply explore these rich cultural reasons related to why some Latino youth use drugs. This can ultimately help inform more relevant drug use reduction strategies and also decrease the proportion of Latino youth who come into contact with the criminal justice system for drug‐related offenses.
