The vocal attractiveness stereotype: Replication and elaboration

We examined personality impressions on five NEO subscales (Costa & McCrae, 1985) as a function of senders' vocal and physical attractiveness. There were four major findings: (a) both vocal and physical attractiveness produced more favorable ratings, and these effects were more pronounced in a single channel (voice only or face only, respectively) than in a multiple channel (voice plus face); (b) the influence of attractiveness, both vocal and physical, was moderated by subscale—the effect of vocal attractiveness was most pronounced for Neuroticism and nonexistent for Agreeableness; the effect of physical attractiveness was most pronounced for Extraversion and nonexistent for Conscientiousness; (c) a vocal attractiveness × physical attractiveness interaction indicated that effects of the two stereotypes were particularly strong for senders who were attractive on both channels; (d) the effects of attractiveness, both vocal and physical, diminished when judges were familiar with the target persons.This research was supported in part by National Institute of Mental Health Grant RO1 MH 40498.     

The relative equivalence of senders in studies of nonverbal encoding and decoding

As an aid to researchers who study encoding and decoding of nonverbal cues, we compared the relative equivalence of encoders sending a single scene with the relative equivalence of scenes when one encoder sent many scenes. Length-corrected internal consistency was identical in both cases, indicating that no necessary gain in generality results from employing more senders each of whom sends fewer scenes rather than one sender who sends more scenes.Preparation of this paper was supported by a grant from the Milton Fund of Harvard University to the first author and by a grant to the second author (BRSG Grant 5 So 7 RR07041-11) awarded by the Biomedical Research Support Grant Program, Division of Research Resources, National Institutes of Health.     

Accuracy of nonverbal communication as determinant of interpersonal expectancy effects

The person perception paradigm was used to address the effects of experimenters' ability to encode nonverbal cues and subjects' ability to decode nonverbal cues on magnitude of expectancy effects. Greater expectancy effects were obtained when experimenters were better encoders and subjects were better decoders of nonverbal cues and the separate contributions of experimenter's and subject's nonverbal skills were of similar magnitudes.The authors wish to express their thanks to Rena Baskin for her help.Preparation of this article and the research described was facilitated by a grant [GS-3942] from the Division of Social Sciences of the National Science Foundation to Robert Rosenthal.     

How Does Centrality in Coopetition Networks Matter? An Empirical Investigation in the Mobile Telephone Industry

This research examines how a firm's position in a coopetitive network (formed through cooperation among firms within an industry) influences the extent of the firm's competitive aggressiveness and market performance. The authors collected data on the competitive and cooperative actions of firms in the mobile telephone industry from 2000 to 2006, using structured content analysis of news reports. The results show that the centrality of a firm in a coopetitive network contributes to the firm's competitive aggressiveness through increased volume and variety of competitive actions. Further, the more central a firm is in the network, the greater is its market performance. Firms that undertake more volume and variety of competitive actions improve their market performance. Overall, these results show that being in a central position in a coopetition network is quite advantageous for the firm.     

Distribution and Expected Time of Residence for U.S. Households

For risk assessments, the average current residence time (time since moving into current residence) has often been used as a surrogate for the average total residence time (time between moving into and out of a residence). Since the distributions of the two quantities are not necessarily the same, neither are their averages. Housing surveys provide current residence time data; total residence times must, therefore, be inferred. By modeling the moving process, the total residence time distribution can be estimated from current residence time data. Using 1985 and 1987 U.S. housing survey data, distributions and averages for both current and total residence times were calculated for several housing categories. The average total residence time calculated for all U.S. households, 4.6 ( se = 0.6) years, is less than half the average current residence time, 10.6 ( se = 0.1) years.     

East meets West: a case example of knowledge transfer

This article highlights some of the similarities and differences in management theory and practice between the UK and the Former Soviet Union (FSU) and Central and East European (CEE) states. It does so in the context of a debate over the appropriateness and extent of cultural dominance in knowledge transfer of theory and practice, which has occurred during the last decade, and which is still unresolved. It reviews a scheme for knowledge transfer which offered a flexible structure within which the organizers could amend their material in the light of their growing experience with the way in which the scheme operated, and whereby they might avoid some of the mistakes of cultural dominance made within other schemes offered elsewhere The Joint Industrial and Commercial Attachment Programme (JICAP), its structure, approach and some outcomes are outlined as a case example. Sponsored by the British Council to arrange visits by middle and senior managers from the post-command economies to the UK for intensive management training and work placement in an organization complementary to their home employment, JICAP was typical of the best Western thinking in management development of the time. The espousals and realities, the benefits and flaws in this approach are examined, drawing on the perceptions of the JICAP delegates themselves in terms of their personal and business development. Czarniawska's model of the travel of ideas (Czarniawska and Joerges 1996) is used as an organizing framework within which the problems of knowledge transfer, culturally dominant or maximally flexible, can be examined, and the underlying issues identified. This notion of flexibility, within which alternative perspectives can be negotiated and new meanings created, constitutes the main contribution proposed by this paper.     

Considering the best interests of infants in foster care placed separately from their siblings

This article offers a perspective on the child welfare practice of placing infants and their siblings in foster care using the theoretical frameworks of attachment and infant mental health. The authors highlight issues for child welfare workers to consider when determining if moving an infant or young child from one home to another for the purpose of placing him with his siblings would cause trauma or disruption; and also issues to consider when determining the infant or young child's best interest when separated from siblings. First, the authors summarize the literature regarding attachment relationships and attachment disruptions. Then, they review outcome studies of children residing in foster care who are placed with their siblings and of those who are placed separately. Finally, the authors conclude with specific recommendations for child welfare workers to aid in making such difficult decisions about placing infants in foster care.     

The effects of temperature on human fertility

Monthly birth and temperature data for a variety of states and countries are used to estimate the effect of short-run temperature fluctuations on fertility. Regressions of monthly births on a flexible specification of lagged monthly temperature show that temperature has quantitatively important effects on both seasonal and nonseasonal variation in births. Summer temperature extremes reduce conceptions in the southern United States, explaining a substantial part of the observed seasonal birth pattern. Extreme cold shows no evidence of affecting conceptions. The results also show significant seasonality in births even after accounting for temperature. Controls for monthly temperature do not explain the persistent spring peak in births in northern Europe. This finding suggests that other factors play an important role.
