Effects of fear of negative social evaluation in interaction with potential partners: experimental study of first encounters / Efectos del temor a la evaluación social negativa en interacción con parejas potenciales: estudio experimental de los primeros encuentros

Abstract

This study used an experimental procedure to evaluate the effects of fear of negative social evaluation (FNSE) on courtship strategies and the ability to interact with the opposite sex. 108 university students participated in this study with a mean age of 19.6. Prior to the experimental procedure, FNSE levels were measured. Then two photographs of people of the opposite sex were shown, one more attractive than the other, and the participants were informed that they would meet one of them. Levels of anxiety and self-presentation motivation (SPM) were measured before the planned interaction. Results show that people with low levels of FNSE have positive expectations of reciprocity when they are about to meet a person that they find attractive. Women, but not men, with high levels of FNSE report higher SPM with less attractive people than with more attractive people. High levels of FNSE are associated with a loss of calm in the situation of meeting a person of the opposite sex. Implications of these results are discussed in the context of courtship strategies.     

Capacity constraints and the dynamics of underwriting profits

The presence of an underwriting profit cycle in property/liability insurance has become a stylized fact. Models of this'underwriting cycle'imply that the insurance market is governed by two regimes, as capacity is constrained or not. We apply the smooth transition regression model to insurance industry data for 1934–1993 to test for a regime shift. We find a rapid shift between two distinct regimes with different dynamics. When capacity is not restricted, we find no evidence of a cycle. The cycle is present in periods when capacity is restricted, immediately following World War II and after 1968. The underwriting cycle appears to be a recent phenomenon.     

The effects of smoking laws on seating allocations of restaurants, bars, and taverns

Supporters of smoking laws often argue that they do not harm restaurants, bars, and taverns and may even raise their profits. Opponents argue that owners cater to customer preferences regarding smoking and that laws mandating specific smoking policies will therefore negatively impact profits of some firms. This article tests hypotheses regarding how smoking laws affect seating allocations, using data from a nationwide survey of restaurant and bar owners. The empirical evidence indicates that smoking laws exert no significant effect on seating allocations. Firms are shown to allocate greater shares of seating to nonsmoking use when customers exhibit stronger preferences for such seating.

Use of a case study in sequencing/scheduling research

This paper describes a study of an industrial sequencing/scheduling problem. The study contains the definition of the problem, data requirements and examination of solution technique. Definition of the problem is discussed from the aspect of uniqueness of the specific system. Discussion of data requirements includes availability and accuracy, while examination of solution technique considers limitation of time, computer capacity, etc., as well as the possibility of imbedding available algorithms into the solution procedure. Conclusions are presented relative to the use of the case study approach in sequencing/scheduling research.     

Variations in horizontal and vertical individualism-collectivism in four regions of Mexico / Variaciones en el individualismo-colectivismo horizontal y vertical en cuatro regiones de México

Cultures can be analysed through cultural syndromes (shared patterns of beliefs, attitudes, norms, roles and values organized around a theme). One of these syndromes, individualism-collectivism, distinguishes collectivist cultures, which prioritize collective over individual interests, from individualist cultures, which value individual autonomy, achievement and freedom. These dimensions intersect with the horizontal-vertical syndrome, where verticality means the preference for a society organized by hierarchies, in contrast to a horizontal culture, which privileges equality. This paper explores these dimensions using a new instrument in a sample of 990 participants from four regions in Mexico. The results of exploratory and confirmatory factorial analyses show four theoretically congruent factors with adequate levels of internal consistency reaching metric equivalence criteria in three of the four samples. The scores show greater support for horizontal individualism and less support for vertical collectivism. These results are discussed within the context of a cultural shift towards individualism.     

A hierarchical theory of occupational segregation and wage discrimination

Becker's model of discrimination is extended to the case where men exhibit distastes for working under female managers. The distribution of women in the resulting occupational hierarchy depends on the number of women in lower occupations, the wages of male workers in lower occupations, and male distastes for female management. Thus, there exists an occupational sorting function, related to wages, that determines the occupational distribution of women. We integrate this sorting function into a standard wage equation to derive a new decomposition of male-female wage differentials and apply it to a sample of insurance industry workers from the 1988 CPS.     

Unruly women and invisible workers: the shrimp traders of Mazatlán, Mexico

During the 1980s, a group of women from rural communities in the Mexican state of Sinaloa organized a grassroots social movement in order to gain legal access to the sale of shrimp. The movement reached its peak in 1984, with the formation of a shrimp traders union and the establishment of a shrimp marketplace in the tourist city of Mazatlán. Despite the long trajectory of the movement and the success of the shrimp market, these women and their work have been completely ignored by government agencies in charge of the development and management of the fishing industry. For the most part, one gets to read about the shrimp traders only in tourist-oriented brochures depicting them as a “local attraction,” something to be seen while one is touring the city on a private charter bus en route to the Archaeological Museum or to the upscale jewelry shops in the Golden Zone. In this article, I examine how women used their gender and their identity as rural workers to defy the state and its policies, overcome poverty, and take control of the local marketing of shrimp. Another objective of this article is to show why and how women engaged in collective action so they could be legitimized as workers and how gender shaped their individual experiences.     

Testing the equality of location parameters of exponential populations from censored samples

The modified Tiku test and the modified likelihood ratio test proposed by Tiku and Vaughan (1991) for k=2 exponential populations are extended to . k > 2 populations. These tests are shown to be more powerful than the test proposed by Kambo and Awad (1985). Unlike the Kambo-Awad test, the proposed tests are shown to have almost symmetric power functions. Further, these tests can be applied when there is both left or right censoring present, in contrast to the tests of Sukhatme (1937), Bain and Englehardt (1991) and Elewa et al. (1992), who assume that there is no left censoring.
