Does Ethnic Diversity Mean Cultural Diversity?

This paper examines the degree of cultural diversity between two ethnic groups in South Florida. The cultural attitudes and causal attributions for unethical work behavior of 269 Anglo and Hispanic business graduate students and of 255 Anglo and Hispanic business executives were investigated. Findings from t-test comparisons for both of these samples suggest a strong agreement between Hispanics and Anglos in their individualism and collectivism orientation, as well as in their process of justifying potentially unethical decisions. Implications for theory, research and practices will be discussed. This revised version was published online in July 2006 with corrections to the Cover Date.     

Factors Affecting Hurricane Evacuation Intentions

Protective actions for hurricane threats are a function of the environmental and information context; individual and household characteristics, including cultural worldviews, past hurricane experiences, and risk perceptions; and motivations and barriers to actions. Using survey data from the Miami‐Dade and Houston‐Galveston areas, we regress individuals’ stated evacuation intentions on these factors in two information conditions: (1) seeing a forecast that a hurricane will hit one's area, and (2) receiving an evacuation order. In both information conditions having an evacuation plan, wanting to keep one's family safe, and viewing one's home as vulnerable to wind damage predict increased evacuation intentions. Some predictors of evacuation intentions differ between locations; for example, Florida respondents with more egalitarian worldviews are more likely to evacuate under both information conditions, and Florida respondents with more individualist worldviews are less likely to evacuate under an evacuation order, but worldview was not significantly associated with evacuation intention for Texas respondents. Differences by information condition also emerge, including: (1) evacuation intentions decrease with age in the evacuation order condition but increase with age in the saw forecast condition, and (2) evacuation intention in the evacuation order condition increases among those who rely on public sources of information on hurricane threats, whereas in the saw forecast condition evacuation intention increases among those who rely on personal sources. Results reinforce the value of focusing hurricane information efforts on evacuation plans and residential vulnerability and suggest avenues for future research on how hurricane contexts shape decision making.     

Approximations to Optimal k‐Unit Cycles for Single‐Gripper and Dual‐Gripper Robotic Cells

We consider the problem of scheduling operations in bufferless robotic cells that produce identical parts using either single‐gripper or dual‐gripper robots. The objective is to find a cyclic sequence of robot moves that minimizes the long‐run average time to produce a part or, equivalently, maximizes the throughput. Obtaining an efficient algorithm for an optimum k‐unit cyclic solution (k ≥ 1) has been a longstanding open problem. For both single‐gripper and dual‐gripper cells, the approximation algorithms in this paper provide the best‐known performance guarantees (obtainable in polynomial time) for an optimal cyclic solution. We provide two algorithms that have a running time linear in the number of machines: for single‐gripper cells (respectively, dual‐gripper cells), the performance guarantee is 9/7 (respectively, 3/2). The domain considered is free‐pickup cells with constant intermachine travel time. Our structural analysis is an important step toward resolving the complexity status of finding an optimal cyclic solution in either a single‐gripper or a dual‐gripper cell. We also identify optimal cyclic solutions for a variety of special cases. Our analysis provides production managers valuable insights into the schedules that maximize productivity for both single‐gripper and dual‐gripper cells for any combination of processing requirements and physical parameters.     

Family Time and the Psychosocial Adjustment of Adolescent Siblings and Their Parents

This study examined the implications of family time for firstborn and secondborn adolescent offspring, mothers, and fathers in 192 dual‐earner families, defining family time as time shared by the foursome in activities across 7 days. Data were gathered in daily telephone interviews. For firstborns, higher levels of family time at Time 1 predicted less involvement in risky behavior 2 years later, controlling for Time 1 risky behavior. Longitudinal analyses predicting depressive symptoms revealed family time X parent education interactions for firstborns, fathers, and mothers, suggesting that the implications of family time depended on social class. The pattern of results suggests that family time is protective when chosen by family members but not when it represents a default use of time.     

International Perspectives on the Use of Community Treatment Orders: Implications for Mental Health Social Workers

Substantial changes to mental health law and policy have occurredthroughout the Western world during the last decade. The drifttowards control, particularly in the form of Community TreatmentOrders (CTOs), has profound implications for the role of mentalhealth social workers, yet this issue is rarely discussed inacademic literature. This paper seeks to redress this gap inknowledge by examining aspects of law, policy and practice usingthree case studies: Victoria, Australia; Ontario, Canada; andregions of the UK. The paper begins by critically reviewingselected literature on CTOs, revealing competing claims aboutefficacy and their impact upon service users¹ and practitioners.A discussion of policy and practice contexts in the three jurisdictionsis then presented and supported with a typology, to illustratecontrasts and comparisons. In their conclusions, the authorsassert that mental health social workers often have a crucialpart to play in the implementation of CTOs but that this isnot always acknowledged in law and organizational policy. Socialworkers’ roles and responsibilities need to be more explicitlyidentified in mental health law. At the same time, there shouldbe a continuing debate about how such coercive powers fit withcodes of ethics and practice standards, at national and internationallevels.     

Ethnocentrism and History Textbooks: Representation of the Irish Famine 1845-49 in history textbooks in English secondary schools

This case study examines how a topic of Irish history, the Irish Famine 1845-49, is represented over time in history textbooks used in English secondary schools and whether and to what extent ethnocentrism is inherent in this presentation. The concept of ethnocentrism is used as a framework for interpreting the presentation of the topic. A strategy of content analysis of samples of history textbooks from the 1920s, 1970s, 1980s and 1990s to the present is used. The conclusion drawn from the analysis is that the history of the Irish Famine is marginalised in the overall sample and that the textbooks contain examples of both direct and indirect ethnocentrism. The conclusion also highlights the importance of maintaining an intercultural approach when designing school curricula and of providing alternative accounts of history to that of the dominant culture.     

SOCIALLY EMBEDDED IDENTITIES: Theories, Typologies, and Processes of Racial Identity among Black/White Biracials

Current research on racial identity construction among biracial people derives primarily from small convenience samples and assumes that individuals with one black and one white parent have only two options for racial identity: "black" or "biracial." Rockquemore's (1999) taxonomy of racial identity options is used as a framework to synthesize existing research and to generate hypotheses that are explored using survey data from a sample of 177 biracial respondents. The findings support a multidimensional view of racial identity by illustrating that biracial people make various identity choices, albeit "choices" that are differentially available due to an individual's structural iocation.     

Attachment status and complexity of infants' self- and other-knowledge when tested with mother and father

At 13 and 20 months, infants' featural knowledge of self and parent was assessed separately with mother and father. Infants' featural knowledge was measured by a scale that included tasks reflecting infants' knowledge of facial features, spatial location, name, possession and gender. No significant relation between attachment status and featural knowledge was obtained at 13 months when tested with either parent. At 20 months, in contrast, more complex featural knowledge of self and parent was demonstrated by infants who were securely attached than by those who were insecurely attached. Independent of age, however, infants' featural knowledge of their mothers was more complex than that of their fathers, although no differences in self-knowledge were obtained as a function of parent gender. These data are understood in the context of cognitive development and the differences in interactional qualities assessed by attachment status and parent gender.
