Toward integrated global models: From economic engineering to social science modeling

It is argued that political and military variables are so crucial in decision making that they ought to be included in world models. Three projects, including our own, are described in brief to give a sense of the theories and data that have been employed in some existing global modeling efforts based on this assumption. The project entitled Computer Simulations for Decision Making in International Affairs utilizes an adaptive macromodel of global political, military, and economic processes into which a host of empirically based minimodules are introduced. The Nations in Conflict studies have focused thus far on an econometric model comprised of three primary components: domestic growth and external expansions, competition for foreign resources, market, allies, and strategic advantage, and the dynamics of crisis behavior. The Alker simulation studies have utilized artificial intelligence techniques to study the structuring and restructuring of international systems of social interaction.The theoretical and empirical materials developed in these projects are highly relevant to the enterprise of integrated global modeling. The earliest efforts were begun to build models of the political and military components of international processes. Subsequent world modelers of the Forrester-Meadows inspired genre focused on the economic aspects of the globe, including its demography. It is argued that the convergence of these two traditions be accomplished in a synthetic fashion in ongoing as well as future work.     

The Industrial Transformation of Farm Communities: Implications for Family Structure and Socioeconomic Conditions

Abstract The industrialization of agriculture has resulted in extensive declines in the number of farms and in the number of people employed in agriculture. For many farm communities, this has resulted in rapid population declines. Other farm communities have been able to attract alternative sources of employment. This study analyzes family structure and socioeconomic conditions in 281 Great Plains counties that were economically dependent on agriculture at one time. Surprisingly, it was found that, while communities remaining agriculturally dependent had extensive population declines, they also had higher rates of employment, lower poverty rates, higher proportions of married couple households, and income levels equal to counties now economically dependent on nonfarm industries. Conditions in counties that have become service based were especially troubling.     

Closed-Form Deterministic End-to-End Performance Bounds for the Generalized Processor Sharing Scheduling Discipline

The Generalized Processor Sharing (GPS) schedulingdiscipline is an important scheduling mechanism that can support both class isolation and bandwidth sharing among different service classes, thus making itan appealing choice for networks providing multiple services with Quality-of-Service guarantees. In this paper, we study a broad classof GPS networks known as Consistent Relative Session Treatment}(CRST) GPS networks and establish closed-form end-to-end performance boundsfor CRST GPS networks. This result generalizes the results of Parekhand Gallager (1994) where simple, closed-form end-to-end performancebounds are derived for a special sub-class of CRST GPS networks, theso-called Rate Proportional Processor Sharing (RPPS) GPS networks, but performance bounds for the general CRST GPS networks do not haveclosed-form. Our result is obtained through the notion of CRSTpartition, which in fact yields a broader class of CRST GPS networksthan the one originally defined in (Parekh and Gallager, 1993). Moreover,our approach is quite general. It not only applies to the deterministicanalysis of GPS networks, but can also be employed in the study of GPSnetworks in a stochastic setting.     

Nationalism and the Linguistic Rights of Deaf Communities: Linguistic Imperialism and the Recognition and Development of Sign Languages

This paper examines the impact of nationalism on the linguistic rights of Deaf communities. In exploring the subtle hegemony of nationalism in relation to linguistic minorities, the paper discusses the impact of nationalisms on sign languages from two perspectives and in two contrasting situations. First, the paper examines the impact of nationalism on the recognition and promotion of natural sign languages. Second, it examines a particularly potent form of linguistic imperialism as the dominant linguistic forces seek not only to destroy minority languages but to transform existing minority linguistic processes to conform with the form and content of the national language, through the development and promotion of manually coded versions of national spoken and written languages in formal education. These issues are examined in relation to the nationalisms and indigenous sign languages of Australia and Indonesia.     

Understanding the diverse needs of the Medicare population: implications for Medicare reform

Meeting the health care needs of millions of elderly and disabled Americans is central to the debate over Medicare's future. Using data from a nationally representative survey of 3,309 beneficiaries, Medicare's most vulnerable beneficiaries were profiled, examining variations in coverage, satisfaction, access, and financial difficulties. A substantial portion of the Medicare population--two thirds--were found to have health problems or low incomes. The analysis found that about 40% of beneficiaries with incomes below the poverty level, in fair or poor health, or with ADL limitations, have difficulties paying their medical bills or getting needed health care. Medicare's disabled, under-65 beneficiaries are at even higher risk: nearly half (47%) have health care access problems or deal with financial hardship due to medical bills. The diverse needs and experiences of the Medicare population are underscored, providing new insights into the challenge of maintaining or improving protection for those with greatest need while assuring the long-term fiscal viability of the program.     

Situational Power and Interpersonal Dominance Facilitate Bias and Inequality

A model is proposed that describes interpersonal phenomena that maintain intergroup hierarchies and conflict. Situational control and interpersonal dominance are identified as conditions that promote motives to stereotype, leading to cognitive and judgment biases that cumulatively reinforce the status quo. Three general hypotheses are derived from the model. First, powerholders are predicted to use attention strategies that favor stereotype maintenance, stereotyping subordinates by default (ignoring counterstereotypic information) and by design (increasing attention to stereotypic information). Second, high-dominance perceivers are predicted to respond with the same cognitive biases as people with situational power. Finally, power and dominance are predicted independently to facilitate bias in explicit judgments. Results from our research program support the hypotheses. Implications for future change are discussed.     

When the relationships fail: A microperspective on consumer responses to service failure

This article investigated the consumer response mechanism in a service failure context. A service failure response model was introduced that incorporated emotive antecedents, a mediation process, and 4 behavioral outcomes. Data were collected via an online survey (N = 371) and further analyzed using the structural equation modeling approach. The results confirmed the service failure response model: Anger and dissatisfaction were emotive antecedents that lead to consumers’ exit, voice, and revenge responses. This process was mediated by desire for avoidance and desire for revenge.     

You are where you live: Methodological challenges to measuring children’s exposure to hazards

Many of the challenges that affect children living in poverty are directly related to the neighborhoods in which they live. Places that inhibit healthy living and those that expose children to environmental pollution tend to more heavily affect children in poverty. This environmental injustice is a natural concern of the fields of urban planning, geography, and children’s health. Yet many decisions that affect opportunities for healthy living are made without a full understanding of how neighborhood context influences such opportunities. In this brief, we paint inequalities in child health outcomes as a spatial problem, review some of the geospatial tools used by urban planners and geographers, discuss common reasons for misclassification or misrepresentation of spatially explicit problems, and propose more suitable methods for measuring opportunities and exposures germane to the field of child poverty. Throughout, we emphasize the need for evidence-driven, spatially grounded responses to child poverty issues with a spatial dimension.     

The Symbolic Type Revisited: Semiotics in Practice and the Reformation of the Israeli Commemorative Context

Revisiting Grathoff's theory of symbolic type (ST), we examine the personal evolution and commemorative work of Tsipi Kichler, a cultural entrepreneur and founder of an alternative Israeli Holocaust museum/geriatric center. As hybrid product of Israeli social cleavages, Kichler exteriorizes her paradoxical vision in the museum aiming to reform Holocaust‐related discourse and practice. Early biographical positioning and resultant contradictions become translated into resistant commemorative performance where serious humor deconstructs the binaries of life/death and past/present. We consider the implications of the ST's self‐referential closure to interaction, and the transformative potential of the alignment of cultural entrepreneurs' personal memory with collective memory.     

The Association Between School Stress,Life Satisfaction and Depressive Symptoms in Adolescents: Life Satisfaction as a Potential Mediator

The aim of the present study was to investigate the interrelationships between school-related stress (school performance, teacher interaction), life satisfaction, and depressive symptoms, as well as the potential mediating role of life satisfaction on the association between school-related stress and depressive symptoms. A total of 1,239 adolescents (13–18 years of age) from public elementary and secondary schools in mid-Norway participated in the school-based survey. The data were analysed using structural equations modelling. The present study showed that stress of school performance was significantly and positively related to depressive symptoms and significantly and inversely related to life satisfaction. At the bivariate levels, stress of teacher interaction was associated with more depressive symptoms and reduced life satisfaction. However, these associations were non-significant in the multivariate analyses, controlled for stress of school performance. A significant inverse association was found between life satisfaction and depressive symptoms. Further, life satisfaction partly mediated the association between stress of school performance and depressive symptoms. The results reflect the complexity of the interaction between adolescents’ experience of school performance stress and mental health, and the role of life satisfaction as a potentially relevant mediator of this association.
