The corporate energy policy: A management planning perspective

The energy problems facing the world have been receiving increasing attention in the press and in business journals. This article examines the attitudes of 224 U.S. business executives toward the energy crisis and examines the role of a corporate energy policy in minimizing the economic impact of future energy price increases and/or shortages. A plan for a corporate energy policy is proposed.     

Telling and Re‐telling Stories: The Use of Narrative and Drawing in a Group Intervention with Parents and Children in a Remote Aboriginal Community

The Let's Start Parent‐Child Program is a manualised parent‐child program which aims to improve educational, social and emotional outcomes for Aboriginal parents and their four‐ to seven‐year‐old children. It has been implemented in the Northern Territory, Australia on the Tiwi Islands and in Darwin since 2005. This paper outlines the adaptation of the program to include narrative approaches, the sharing of stories and the use of expressive arts as a way to build understanding between program leaders and participating families. An example from a recent program is used to illustrate how the sharing of stories and expressive use of art engages and binds group participants together. It supports parents to tell their own stories, to speak about their lived experience, to reconsider aspects of their own and their children's experiences and to achieve an increased awareness of their personal resources and a sense of self‐empowerment. The program is designed and delivered with sensitivity to individual parents, children and families, where cultural and interpersonal differences and different developmental and family situations can be taken into account.     

Academic economists behaving badly? A survey on three areas of unethical behavior

This article measures the degree to which academic economists have engaged in unethical behavior and the degree to which academic economists believe the profession as a whole engages in unethical behavior. Three main types of unethical behavior are examined: (1) falsification of research; (2) expropriation of graduate student research or including an undeserving co-author on a research paper; and (3) exchange of grades for gifts, money, or sex. Using a unique data set gathered at the 1998 American Economic Association (AEA) meetings, we find that there is a significant amount of misconduct, particularly in the second category.     

Sociology and the Mix Tape: A Metaphor of Creativity

Creative endeavors often resemble one another. This paper explores similarities between sociology and art based on the use of conventions and creativity. More specifically, by comparing the construction of musical mix tapes, the author draws parallels between creating sociology and mix tapes. Looking at the process of how a mix tape is created using other artists’ songs and music for a specified purpose illuminates sociology and our roles as sociologists in a new light that leaves open new possibilities.     

Positive and negative affect: A maximum-likelihood approach

Using the LISREL maximum-likelihood program, the relation between Bradburn's positive affect and negative affect scales is examined for three age groups of adults. It is found that (a) unequal item loadings fit significantly better than equal item loadings; (b) the best-fitting loadings for the elderly are significantly different from those of the non-elderly; (c) the positive and negative affect scales are substantially correlated and (d) correlations with related variables are stronger when positive and negative affect scales are formed by maximum-likelihood loadings rather than by unit loadings. Given the widespread use of Bradburn's scales, implications of these results for subjective well-being are discussed.     

中国股票市场风险因素的相关性研究

近年来国外关于资本资产定价模型(CAPM)的实证研究不断对该模型提出严厉的质疑,其中很多研究认为除了贝塔系数外,市值size、账面市值比be/me、市盈率p/e这三个风险因素都对股票的收益率具有一定的解释能力。然而这些风险因素能否独立地解释股票的收益率还没有定论。就因素本身来说,size与p/e之间存在较强的相关性,而be/me与其余两因素之间几乎不存在相关性。就因素对投资组合收益率的解释能力来说,p/e几乎不具有独立的解释能力,size的独立解释能力最强,而be/me在较大公司中有一定的独立解释能力。     

Language delays among foster children: implications for policy and practice

This article highlights the centrality of language in early childhood development and the potential for language delays to negatively affect long-term outcomes in educational and social domains. Given the high rate of language delays in the foster care population, an emphasis should be placed on assessing language skills among children ages 6 and younger entering foster care. The authors describe several existing approaches to assessing language skills and discuss obstacles to the widespread implementation of systematic evaluation among foster children. Finally, the authors discuss the need for research and programming to establish evidence-based practices that encourage the remediation of language delays in this highly vulnerable population.     

GMM with Weak Identification

This paper develops asymptotic distribution theory for GMM estimators and test statistics when some or all of the parameters are weakly identified. General results are obtained and are specialized to two important cases: linear instrumental variables regression and Euler equations estimation of the CCAPM. Numerical results for the CCAPM demonstrate that weak‐identification asymptotics explains the breakdown of conventional GMM procedures documented in previous Monte Carlo studies. Confidence sets immune to weak identification are proposed. We use these results to inform an empirical investigation of various CCAPM specifications; the substantive conclusions reached differ from those obtained using conventional methods.
