The role of group identification in the well-being of Spaniards with gypsy ethnicity

ABSTRACT

Objective: To describe the role of sex, age, educational level and psychosocial group-identification factors in well-being and satisfaction with life. Method: 229 Spanish Gypsies completed a survey of demographic data, psychological well-being, life satisfaction, ethnic identity and the individual’s inclusion of self within the ingroup. Results: (a) only level of studies is related to satisfaction with life; (b) participants with higher scores in ethnic identity reported more well-being and more life satisfaction; and (c) assessment of ethnic belonging affects more areas of well-being than does perception of closeness to the ingroup. Conclusion: objective conditions of deprivation are not related to well-being as reported by the participants; it is important to study how Spanish Gypsies value and perceive their ethnicity in order to predict their well-being and satisfaction with life.     

The American South: Explorations on southern attachments and personal values

ABSTRACT

Group membership is central to understanding political behavior and political psychology. However, regional group membership is rarely examined, despite its relevance to political psychology and personal values. To address this, we investigated the relationships among southern identity, southern nationalism, southern pride, and southern constructive patriotism for the U.S. South, as well as the connections between personal values and southern attachments. Results from the structural equation modeling (N = 268) revealed that stronger southern identity predicted more southern nationalism, southern pride, and southern constructive patriotism. Additionally, greater endorsement of conservation values predicted stronger southern identity and southern pride; those favoring self-transcendence values exhibited less southern nationalism and more southern constructive patriotism; and those with higher self-enhancement values expressed more southern nationalism. This study confirms the predictive role of southern identity on other southern attachments and provides support for how different southern attachments are related to but distinctive from each other.     

Group decision as a twice multicriteria optimum problem

This paper studies the problem of aggregation of preferences, preserving the multicriteria nature of the individual decision process. The resulting group decision problem is in effect a twice multicriteria optimum problem. We give a structural theory for the efficient set of this optimum problem. Moreover, on the basis of this theory we study the relationships between optimality, consensus and evaluation. We confirm the pathological nature of aggregation of preferences, but in a new setting and with a different meaning.     

Study of unique merging behavior under mixed traffic conditions

Roads in developing countries carry mixed traffic with wide variations in static and dynamic characteristics of vehicles. The traffic flow is also generally devoid of lane discipline, with vehicles occupying any available road space ahead. In such a regime of traffic flow, the phenomena of merging of vehicles at intersections of two roads is complex, warranting further study. The merging maneuvers at T-intersections under congested traffic conditions were studied microscopically through video-recording. In congested situations, the merging vehicle attempts a complex merging maneuver to enter the main traffic stream. Two unique merging processes are commonly observed in mixed traffic: group and vehicle cover merging (these are generally not observed in countries such as US). The author is using these words first time in this study. These reflect the different types of driver behavior – merging in groups, and by taking cover of another vehicle. Probabilistic models for group and vehicle cover merging are developed that capture this unique merging behavior. Comprehensive microscopic data collection and extraction were carried out to study the merging process at T-intersection under congested conditions. Merging models were then estimated using maximum likelihood method with disaggregate data that was collected for a case study T-intersection in Chennai city, India. Such models can find applications in simulation of highly congested traffic flow in a realistic manner under mixed traffic conditions. They can also give insights on devising better traffic control measures at such intersections.     

Aggregating preference rankings: An AHP-based approach

The problem considered here involves the selection of an alternative by a group of decision makers in a context that involves the aggregating of votes from a preferential ballot. A popular approach for solving such problems is the well-known weighting problem formulation. However, with such a formulation two issues become of critical importance: (a) the weights should reflect the decision-making group's belief on the importance of each rank position and (b) the weights should accord each alternative a fair (if not its best) assessment. Many researchers have studied this problem and proposed various solution strategies. None of these strategies, however, appears to have adequately addressed both issues. The objective of this research is to develop a group decision-making model that solves the problem in a manner that adequately addresses the two critical issues identified, as well as allows for sensitivity analysis and is fairly robust with respect to the various paradoxes identified in voting systems.
