A Note on Inconsistency of NPMLE of the Distribution Function from Left Truncated and Case I Interval Censored Data

We show that under reasonable conditions the nonparametric maximum likelihood estimate (NPMLE) of the distribution function from left-truncated and case 1 interval-censored data is inconsistent, in contrast to the consistency properties of the NPMLE from only left-truncated data or only interval-censored data. However, the conditional NPMLE is shown to be consistent. Numerical examples are provided to illustrate their finite sample properties.     

Stages of Change Among Ethnically Diverse College Students

Abstract

The authors applied the stage-of-change construct in the transtheoretical model to examine the distribution of Asian (n = 869), African American (n = 373), White (n = 1322), and Hispanic (n = 535) American undergraduate students across the 5 stages of change for exercise. Stage of change varied as a function of ethnicity. Higher percentages of minorities were in the precontemplation and contemplation stages. The likelihood of being in these stages was from 43% to 82% greater for minorities than for White students. Also examined were the congruency between stage of change and self-reported levels of physical activity. Half of the sedentary students and 15.6% of the active students were misclassified by the stage-of-change procedure. Misclassification rates were higher for minority women (27.8%) than for White women (17.8%) and for Asian students (24.6%) compared with all others (20.6%). The results of this study have implications for the design of physical activity interventions based on stage of change.     

Jose Marti’s Confederate Affinities

ABSTRACT

Jose Marti examines the American Civil War and the period of Reconstruction through the lens of Cuba’s failed attempts at independence as a way of disenchanting modernizers and annexationists who, seeking rapprochement with the U.S., would compromise South American and, more specifically, Cuban sovereignty. More to the point, as much as Marti draws parallels between Cuba and the U.S. South vis-à-vis Spain and the U.S. North, respectively, his troubling affinity with the Confederacy and the postbellum South chiefly exposes the North’s ideological elision of its imperial project.     

The Influence of Gaming Expenditure on Crime Rates in South Australia: A Local Area Empirical Investigation

Although there has been much speculation about the possible links between gambling and crime rates, relevant quantitative evidence has been practically non-existent in Australia to date. This paper reports the results of research that utilised a model designed to investigate the potential relationship between electronic gaming machine expenditures and property (income-generating) crime rates reported to police in local areas in South Australia in 2002–2003. The research found that the higher the expenditures on gaming machines in a particular local area per adult, the higher the income-generating crime rate in that area. No such relationship was found between gaming machine expenditure and non-income-generating crime rates. However, further research is required before any policy-relevant conclusions can be drawn.     

Explaining the association of race and ethnicity with the HIV/AIDS-related attitudes,behaviors and skills of high school students

This study deals with intervening factors such as family composition, religiosity, and HIV/AIDS knowledge in understanding the association of race and ethnicity with HIV/AIDS-related attitudes and behaviors. Data represent Wave 1 of a five-month panel design involving 10th grade students in eight public high schools in Dade County (greater Miami) Florida. Significant differences in attitudes and behaviors were found among racial/ethnic groups. Specifically, Hispanics had more negative attitudes about condom use than blacks or whites. Whites had the most permissive, and blacks the least permissive, sexual attitudes. Hispanics felt least confident and blacks felt most confident about interpersonal sexual skills. Blacks were most likely to have had sexual intercourse, and whites least likely. Religiosity was found to be a significant intervening variable in the less permissive sexual attitudes of both blacks and Hispanics. The most significant implication of this study is that racial/ethnic differences in sexual behavior can be explained more fully by socio-environmental factors such as family structure or religiosity than by knowledge or attitudes. Thus, interventions directed toward minority populations should focus on the development of alternative social environments that would support more positive behaviors. More specifically, extended family, religious youth groups, and other community organizations should be brought into the HIV/AIDS risk-reduction arena.     

The Dynamic Capability View in Strategic Management: A Bibliometric Review

The dynamic capability view (DCV) is one of the most vibrant approaches to strategic management. In this study, the extant literature published between 1994 and 2011 is analysed, using bibliometric methods in order to explore the scope of this approach and detect current research priorities. For this purpose, the method of bibliographic coupling is introduced in management research, which shifts the focus of analysis from past traditions to current trends. Several clusters of thematically related research are extracted from bibliographic networks, which represent interconnected yet distinct subfields of inquiry within the DCV. The core cluster of the current DCV, which visualizes this research field's nascent but fragile identity, focuses on learning and change capabilities and relates them to firm performance, thus merging aspects of organization theory and strategic management. In addition, several peripheral clusters of research are identified, which reflect a parallel process of differentiation in the overall field. Both trends, i.e. of integration and differentiation, attest to the emancipation of the DCV as a distinct approach to strategic management. However, the DCV still lacks consensual concepts that allow comparisons of empirical studies and advance the theoretical understanding of dynamic capabilities. In the light of the above, some implications of this analysis for further research are discussed.     

International Experience in International Business Research: A Conceptualization and Exploration of Key Themes

International experience, the experience that firms accrue from operating internationally, is a key concept in explaining firm internationalization. This paper reviews the conceptualization of international experience in the international business literature. It highlights how prior research has identified three dimensions of the international experience construct (length, scope and diversity), thereby demonstrating that international experience should be treated as a multidimensional construct. In addition, intensity is presented as a fourth and novel dimension of international experience. The importance of this multidimensional conceptualization is highlighted in an explanation of why the international diversification and international experience constructs are not synonymous. In light of the importance of international experience in explaining firm internationalization, the authors explore how the source of the firm's international experience will determine the limits to its application in foreign markets. In particular, the authors distinguish between location‐bound international experience and non‐location‐bound international experience as sources of firm‐specific advantages (FSAs). The FSAs that the firm develops from its experience with equity and non‐equity entry modes are presented as examples of specific FSAs developed within the firm's bundle of FSAs concerning internationalization. The paper concludes with some implications of the conceptualization of international experience for several issues of international business research as well as providing managerial implications.     

Vertical Coordination,Producer Response,and the Locus of Control over Agricultural Production Decisions1

Abstract Structural change in U.S. agriculture in part has been characterized by shifts in control over agricultural production decisions from the farm-level to off-farm firms. In the past decade, this process has accelerated as increasing concentration in production and processing has led to increased vertical integration and contract production. To retain control, some farmers have formed bargaining units, have created production and marketing networks, and have petitioned subnational state governments for regulation of production contracts. Concurrently, there has been an impressive increase in alternative marketing outlets linked with smaller-scale production based on farm-level control over production decisions. Structural change and producer collective response has a long history in U.S. agriculture. Using Mooney's and Hunt's (1996) recent contribution on recurrent ideologies of agrarian social movements, this paper outlines recent structural changes and collective responses to those changes with reference to the shifting locus of control over agricultural production decisions.     

The Production Function,Crop Diversity,and the Debate Between Conventional and Sustainable Agriculture1

Abstract Organizational assumptions embedded in the production function of neoclassical economics have served to structure production agriculture in the United States for the past 100 years. The narrow focus of the production function on the inputs of land, labor, capital, and management and the use of on-farm profitability as the primary definition of sustainability have come under attack from sustainable agriculturalists, who argue that the social and environmental consequences of production are as important as the economic outcomes. Using diversity of crops harvested as an indicator of sustainability, the production function is operationalized to inform the debate between the conventional, neoclassical model of production and the alternative, sustainable model. Census of agriculture data from 1978, 1982, and 1987 are used in both cross-sectional and temporal models. Results show that increases in expenditures for equipment and machinery, prevalence of corporate farms, higher rates of tenancy, and the prevalence of large farms are associated with lower levels of diversity at the county level. Conversely, higher levels of diversity are found in counties with greater farm labor expenses, where there are more medium-size farms, and where farmers are more likely to farm full-time.
