Empirical studies have shown that cyclical preferences are infrequent, but they have been less clear about why. Using thermometer ratings from nationally-representative samples of the U.S., we examine preferences for presidential candidates in order to determine what it is about them that leads to few cycles. Single-peaked preferences as usually construed (meaning that all of a set of preferences satisfy single-peakedness criteria) are, of course, rare. Yet we find a high degree of unidimensionality in the sense that for any given set of preferences, a relatively high proportion of the preference orders are consistent with single-peakedness. We also find that the highest amounts of unidimensionality often do not occur along partisan or left/right lines. Strong feelings for or against candidates, often not derived from an issue base, form the basis for the dimensionality discovered.We would like to thank Daniel Severance for programming the random model calculations and three anonymous referees, whose comments were very helpful in clarifying the presentation in this paper.  相似文献

The verbal and nonverbal communication of warmth was examined in a study in which undergraduate women taught a block design task to a listener who was either a six-year-old child, a retarded adult, a peer who spoke English as a second language (foreigner), or a peer who was a native speaker of English. The degree of warmth conveyed by the speakers differed only minimally across different categories of listeners. However, these communications did vary systematically within each category, in accord with the levels of cognitive and linguistic sophistication of each particular listener. Speakers tended to fine-tune communications by conveying more warmth to the more sophisticated children and foreigners than to the less sophisticated members of these categories. To the more sophisticated retarded persons, however, they conveyed—nonverbally—less warmth than to the less sophisticated retarded persons. The relevance of these findings to the communication of expectancy effects and to the social psychology of stigma is discussed.This paper was written while the first author was visiting at the University of Florida.

An experiment was designed to examine the role of a person's predispositions toward communication in reactions to violations of proxemic expectations. Working with Burgoon's (1983) violations of nonverbal expectations model, Buller and Burgoon (1986) predicted that predispositions may bias evaluations of initiator reward and violation valence. Apprehensive individuals should unfavorably evaluate the initiator, negatively valence a violation and comply less, while nonapprehensive individuals should favorably evaluate the initiator, positively valence a violation, and comply more. Alternately, this paper proposes that predispositions may affect arousal-induction rather than initiator evaluation and violation valencing. Following Patterson (1983), apprehensives should experience more arousal and comply more to reduce the arousal, whereas nonapprehensives should experience less arousal and comply less. Four initiators engaged 90 subjects in experimental conversations which ended with a request for the subjects' signature on a petition. Initiators either remained at the normative distance, moved one seat closer, or moved one seat farther from the subject. Results showed that apprehensives and subjects experiencing close violations complied more, suggesting that communication apprehension influences arousal-induction. Communication apprehension had no main effect on perceptions of initiator attractiveness and similarity, implying that arousal not perceptions of the initiator is affected by predispositions toward communication. Initiator gender again emerged as an important characteristic which influences a subject's perceptions of initiator reward.  相似文献

Polls taken in late 1980 and 1984 varied by up to 20 pointsin the spread they reported between Democratic and Republicanidentifiers. We found three systematic and sizable differencesacross polls: polls that sample only voters, polls that emphasize"today" or the present in their question wording, and pollsthat are taken close to election day (at least in circumstanceslike those of 1984) tend to favor the party currently advantagedin the presidential race.  相似文献

Evidence of self reported morbidity from two household surveys, carried out in London and Manchester is discussed. These data permitted intra-urban and interurban comparisons of patterns of morbidity reporting. The morbidity reported in response to two different instruments is compared: for the items used in the British General Household Survey (GHS) Health Section, and for the Nottingham Health Profile. The results from the London survey are analysed in more detail to examine the nature of self reported morbidity in the inner and outer city. The influence of interviewer effects is analysed, showing that the GHS items were more liable to interviewer effect than the NHP. The type and number of illnesses reported in response in response to the GHS also appeared to vary between the inner and outer London samples: The NHP appeared to be less affected by interviewer effects and variation in interpretation.  相似文献

Knowledge is a vital source of competitive advantage and renewal for contemporary organizations. However, to date, few studies have scrutinized how mergers and acquisitions (M&As)—processes dependent on knowledge sharing—offer a valuable inter-organizational context through which to understand the attainment of customer knowledge sharing following M&As. Applying an integrated theoretical perspective from customer relationship management and M&A performance research, we study a Chinese–Finnish acquisition and customer firms of the acquired party across four advanced Western countries. We find that customer knowledge sharing is an active relationship management process that relies on the factors of customer dedication-based motivation vs. customer concerns about M&As to maintain relationships after acquisitions. In addition, and more importantly, we find that the promise management mechanisms—making promises, enabling promises, and keeping promises—of the M&A parties reinforce the motivational factors to maintain customer knowledge sharing in cross-border M&As. We propose a conceptual framework of customer knowledge sharing in cross-border M&As.  相似文献

This paper examines the mediating mechanism of the relationship between institutional voids (IVs) and inter‐firm cooperation and the moderating role of economic adversity in the context of small and medium‐sized enterprises (SMEs) based in emerging markets. The hypotheses are tested using time‐lagged survey data from 214 SMEs in Ghana. The findings provide support for the hypotheses by showing that: (1) IVs positively influence the use of government research and development (R&D) support; (2) the use of government R&D support mediates the relationship between IVs and inter‐firm cooperation; and (3) economic adversity positively moderates the relationship between IVs and the use of government R&D support. The findings contribute to understanding the role of IVs in inter‐firm cooperation. The wider implications for theory and practice are examined.  相似文献

Model building in physical, statistical, simulation or other form, is making an increasing contribution to the problem solving methodology in economics, industry, government, and technological development (1). More specifically, in the present context, simulation models can offer a distinctive and valuable contribution to the understanding by management of complex business systems, interactions and environment and indicate ways toward improvement, financial and otherwise (2). The advent of powerful computers in the last few years is the decisive factor which has decided the means of realizing the full potential of simulation models, hitherto unattainable because of the vast amount of data processing and calculation required. The purpose of this article is to indicate the approach to and scope of a computerized simulation model for long term production strategy decision making (3). While the model relates to the system and data of a specific production unit, manufacturing electronic components, the principles are widely applicable in any size and type of company. It is not a specifically large company technique.  相似文献
