A DECISION THEORY EXAMPLE IN FOOTBALL

In the 1967 Harvard-Cornell football game, Harvard was ahead 14–0 late in the game when Cornell scored two touchdowns. On both occasions, Cornell tried and failed on the two-point conversion attempt and lost the game 14–12. Postgame arguments were divided on the merits of Cornell's strategy. For this frequently occurring scenario in college football, we derive a maximum expected utility decision rule for the decision of kicking versus running/passing based on the relative utility of a win, a tie, or a loss and the probabilities of success with a kick as opposed to a run/pass.     

COST-VOLUME-PROFIT ANALYSIS IN STOCHASTIC PROGRAMMING MODELS

This paper applies mathematical programming to cost-volume-profit (CVP) analysis under contribution margin uncertainty. Three CVP probabilistic chance-constraint models based on various safety-first criteria for decisions under uncertainty are presented and compared. It is shown that a break-even segment of the mean-standard deviation frontier is a set of optimal solutions for the proposed models. An operational parametric quadratic programming (QP) model is constructed, and the efficiency frontier is generated. The procedures for locating an optimal solution on the efficiency frontier are then presented. The recommended QP procedure offers both technical relief from the computational difficulties posed by the probabilistic constraints and a desired flexibility in generating and presenting the relevant information for decisions under uncertainty.     

From Mothers of the “People's Home” to Biologically Rational Consumers

The aim of the present article is to study how women's alcohol consumption has been defined and contested in the Swedish press from 1955 to 2010 in relation to the development of Swedish society from a social democratic welfare state to a neoliberal competition state. Our material consists of articles published in the largest Swedish national and regional newspapers in 1955, 1965, 1977, 1982, 1995, 2004, and 2010. In the study, we apply Fraser's concepts of recognition and redistribution to analyse how the press contributed to the formation of cultural injustices and counter-claims through its recognition of women's drinking, and how these cultural injustices and counter-claims have conditioned the redistribution of societal resources. Our analysis shows that, during the study period, women were recognized in the Swedish press in limited and stigmatizing subject positions. These dominating representations of drinking women changed over time in an unpredictable way. As collectively shared, widely accepted cultural images, they tended to downplay the possibility of women achieving equal and just participation in cultural interaction, social activities, and healthcare services. In counter-discourses, the possibilities for women to formulate public claims in order to make surrounding structures more “enabling” of their independency, weakened during the study period.     

Methods for spatial and temporal land use and land cover assessment for urban ecosystems and application in the greater Baltimore-Chesapeake region

Understanding contemporary urban landscapes requires multiple sets of spatially and temporally compatible data that can integrate historical land use patterns and disturbances to land cover. This paper presents three principal methods: (1) core analysis; (2) historic mapping; and (3) gradient analysis, to link spatial and temporal data for urban ecosystems and applies their use in the Baltimore-Chesapeake region. Paleoecological evidence derived from the geochronology of sediment cores provides data on long-term as well as recent changes in vegetative land cover. This information, combined with contemporary vegetation maps, provides a baseline for conducting trend analyses to evaluate urbanization of the landscape. A 200-year historical land use database created from historical maps, census data, and remotely sensed data provides a spatial framework for investigating human impacts on the region. A geographic information system (GIS) integrates core analyses with historic data on land use change to yield a comprehensive land use and land cover framework and rates of change. These data resources establish the regional foundation for investigating the ecological components of an urban ecosystem. Urban-rural gradient analyses and patch analyses are proposed as the most appropriate methods for studying the urban ecosystem as they link ecological and social patterns and processes for varying degrees of urbanization.     

Crossing the border: immigrant student identities in Swaziland schools

This paper sets out to explore how the resettlement of immigrant students in a host country and schooling context influenced the constitution, negotiation and representation of their identities. Data capture included a mix of semi-structured interviews, focus group interviews, observations and a researcher journal. Data were analyzed by means of the content analysis method. Findings were fivefold. First, the sociocultural context influenced the way immigrant students constructed their identities. Second, categorization was based on phenotypical features, accent, negative attitudes and stereotypical perceptions of immigrants by Swaziland society. Third negotiated identities were multiple in nature and rooted in their culture of origin. Fourth, self-determination was a strong trait of immigrants; reflected in their work ethic, in the resolution of culture conflicts, and in their drive to achieve linguistic competency. And fifth, psychosocial passing was consistent with second generation immigrants. New knowledge generated from this study revealed that African immigrants preferred to be clustered with Mozambican immigrants, as it provided solid ground from which they negotiated identities in Swaziland schools. Mozambican immigrants recruited other African immigrants into their cluster, which they referred to as the ‘Chico nation’. And, the culture of non-Christian immigrants was suppressed to promote Christian religious beliefs and values.     

Finding the niche to reposition leadership in Africa’s developing economies for the global highway: review of literature on leadership development programmes – methods and techniques*

Africa’s developing economies remain in critical need for leadership. This paper asserts that Africa’s new growth opportunities rest with leadership that could champion organizational performance, innovativeness, and good ethics among others. A review of extant literature on leadership development programmes (LDPs) was done to examine possible initiatives that leadership developers can use to influence leadership practices in Africa. This paper proposes that in Africa, LDPs can be used to inculcate authentic leadership practices and enhance networking and acquisition of innovative skills among others. Furthermore, LDPs could target the youth considering them as an investment into tomorrow’s leadership talent pool. The paper suggests that Africa’s niche for the global highway rests in contextualization of LDPs from other regions to Africa’s unique environment.     

Children’s educational attainment,occupation, and income and their parents’ mortality

Using data from Finland, this paper contributes to a small but growing body of research regarding adult children's education, occupation, and income and their parents' mortality at ages 50+ in 1970–2007. Higher levels of children's education are associated with 30–36 per cent lower parental mortality at ages 50–75, controlling for parents' education, occupation, and income. This association is fully mediated by children's occupation and income, except for cancer mortality. Having at least one child educated in healthcare is associated with 11–16 per cent lower all-cause mortality at ages 50–75, an association that is largely driven by mortality from cardiovascular diseases. Children's higher white-collar occupation and higher income is associated with 39–46 per cent lower mortality in the fully adjusted models. At ages 75+, these associations are much smaller overall and children's schooling remains more strongly associated with mortality than children's occupation or income.     

Negotiating Symbolic Boundaries in Conflict Resolution: Religion and Ethnicity in Turkey’s Kurdish Conflict

This article is an inquiry into understanding why supranational religious identity often fails to act as a conflict resolution tool in religiously homogenous ethnic conflicts. Narrowing its focus down to the role of religious elites as potential peacemakers in such conflict zones, it proposes the divergence in their conceptualizations of religious and ethnic identities as an explanatory factor. Building on 62 in-depth interviews conducted in Turkey with Sunni Muslim Kurdish and Turkish religious elites, it identifies a three-fold typology of religious and ethnic identities, as conceptualized by these elites: 1) religio-ethnic; 2) ethno-religious; 3) religious. After exemplifying each category with interview data it demonstrates the role these distinctions play in preventing the successful implementation of “Muslim fraternity” as a solution to the Kurdish conflict in Turkey. With these findings, the article contributes to both the literature on religion in conflict resolution and that on identity formation and boundary making. While it invites the former to turn its gaze from macro-level structural factors to meso- and micro-level cultural factors in analyzing religious elite involvement in conflict resolution, it invites the latter to stop employing “ethnicity” as an all-encompassing term (that covers a vast array of identity markers including religion) and focus, instead, on the gradations between religion and ethnicity as sources of identity.     

The Influence of Career Planning on Career Thoughts in STEM‐Interested Undergraduates

Undergraduate career planning courses have shown efficacy in decreasing students’ negative career thoughts; however, universities have minimally applied these courses to science, technology, engineering, and math (STEM) populations. This study compared the influence of a STEM‐focused career planning course for undecided STEM students with a seminar course for decided STEM majors. An analysis of covariance with covariate adjustment revealed that undecided career planning students had lower adjusted mean scores on a measure of negative career thinking than the decided STEM majors after the first semester of college. The results provide support for the efficacy of STEM‐focused career planning courses and measuring negative career thoughts with STEM undergraduates.
