International cooperation in stockpiles and tariffs for coping with oil supply disruptions

This paper provides a unified treatment of oil stockpiling and demand restraint as policy responses for enhancing energy security and examines the implications of recent changes in the structure and performance of the international oil market for the design of policies. These issues are addressed using a dynamic programming framework in which international policy actions of key oil-importing countries are modeled as a Nash dynamic game. Significant policy implications from the analysis include: (1) the result that, with realistic assumptions about disruption risks and inventory capacities, differences between noncooperative and coordinated stockpile policies appear to be minor and (2) significant mutual gains could be reaped from a modest degree of collective restraint on normal market oil demand. The broader role of international cooperation in enhancing energy security is also discussed.     

DESENSITIZING HERBERT BLUMER'S WORK ON RACE RELATIONS

Recent applications of Herbert Blumer's group position model to the study of contemporary race prejudice have misrepresented the ongoing process of definition and accommodation that, according to Blumer, mediates race relations. By conforming to the canons of research design and using standard sample surveys, public opinion polls, variables analysis, and statistical techniques to study perceptions of group threat, group hostility, and prejudicial attitudes, Blumer's dynamic social imagery, as well as the socially grounded methodology he sought to promote, are undermined. The result is a static depiction of race relations that has nothing to do with the variegated experiential complexities that Blumer claimed underlie all human group life.     

The Symbolic Dilemmas of Suburban Poverty: Challenges and Opportunities Posed by Variations in the Contours of Suburban Poverty1

Poverty has increased significantly in U.S. suburbs since the 1990s. What we know about suburban poverty is largely limited to demographic and economic information. Building off the organizational perspective approach, I use in‐depth interviews with nonprofit, antipoverty organizations in eight Pennsylvania suburbs to better understand the suburban poverty experience. My focus is on how organizations compete for external resources. By working directly with the poverty problem while also working in broader metropolitan political and economic fields of decision making, this “middleman” role ( Marwell, 2007 ) gives us insights into contemporary poverty dynamics for suburbs. I find that how suburban organizational leaders perceive the challenges they face, and what strategies they adopt to confront such difficulties, revolves around symbolic dilemmas posed by the history, distribution, and politics of poverty in the suburbs. Symbolic dilemmas cluster around three different situational contexts of poverty in the suburbs. I use this to develop a three‐part typology of suburban poverty: symbiotic suburbs, skeletal suburbs, and overshadowed suburbs. This typology has implications for future research and for policymakers interested in developing tools to appropriately address this pressing issue.     

Assessing job self-efficacy and organizational commitment considering a mediating role of information asymmetry

This study establishes a model by drawing from key postulates and findings under information asymmetry to explain the formation of organization commitment and job self-efficacy. In the proposed model, organizational commitment and job self-efficacy are influenced indirectly by social support, knowledge creation, and information intensity via the mediation of decision-making quality and perceived opportunism. Knowledge creation is influenced directly by both social support and information intensity. Empirical testing of this model, by investigating personnel from firms in one of Taiwan's well-known industrial zones, confirms the applicability of information asymmetry in understanding employees’ organizational commitment and job self-efficacy. The test results indicate that all the model paths except one (linking perceived opportunism and job self-efficacy) are significant. Finally, the research provides managerial implications and limitations.     

Extreme probabilities for contingency tables under row and column independence with application to fisher's exact test

Theorerms are proved for the maxima and minima of IIR_i!/IIC_j!/T!II_yij ! over r× c contingcncy tables Y=(y_ij) with row sums R₁,…,R_r, column sums C₁,…,C_c, and grand total T. These results are imlplemented into the network algorithm of Mehta and Patel (1983) for computing the P-value of Fisher's exact test for unordered r×c contingency tables. The decrease in the amount of computing time can be substantial when the column sums are very different.     

Developmental Career Counseling with Teenage Parents

Although teenage parenthood is recognized by many counselors as a developmental identity crisis, it rarely has been viewed as a developmental career crisis. This article suggests developmental career assessment and counseling procedures for use with teenage parents.
