Trust me, I'm your boss: Trust and power in supervisor-supervisee communication

This study examined employees' perceptions of trust, power and mentoring in manager-employee relationships in a variety of sectors, including health care, education, hospitality and retail. The main theoretical frameworks used were communication accommodation theory and social identity theory, in examining the manager-employee relationships from an in-group/out-group perspective. Computer-aided content analyses revealed a number of emergent communication and relationship themes that impact upon the level of 'in-groupness' and therefore trust in supervisor-supervisee relationships. While it may be illusory to believe that any organization can enjoy complete trust among its workforce, it is clear that certain communication characteristics can result in greater trust in manager-employee relationships, even within the context of organizational constraints. It is argued that the results of the study could be used to inform human resource management academics of key aspects of managerial communication that should be further researched, and also provide insights into the main communication skills that managers should focus upon to improve trust in the workplace.

Reactions to positive deviance: Social identity and attribution dimensions

This research examines whether evaluations of positive deviates (i.e. high achieving group members) are influenced by the attributions they make for their performance. We argue that ingroup positive deviates who make group attributions help enhance the ingroup's image and thus attract favorable evaluations. In Experiment 1, ingroup positive deviates who made group attributions were generally evaluated more favorably than ingroup positive deviates who made individual attributions. There was also evidence that the positive deviates' attribution style influenced group and self-evaluations. Evaluations of outgroup positive deviates were not influenced by their attribution style. In Experiment 2, an ingroup positive deviate who was successful and attributed that success to the group was upgraded relative to an ingroup positive deviate who made individual attributions. Group evaluations were also higher when the positive deviate made group attributions. This pattern did not emerge when the positive deviate failed. The results are discussed from a social identity perspective.

Why organizational and community diversity matter:the emergence of incivility and organizational outcomes

Integrating sociological and psychological perspectives, this research considers the value of organizational ethnic diversity as a function of community diversity. Employee and patient surveys, census data, and performance indexes relevant to 142 hospitals in the United Kingdom suggest that intraorganizational ethnic diversity is associated with reduced civility toward patients. However, the degree to which organizational demography was representative of community demography was positively related to civility experienced by patients and ultimately enhanced organizational performance. These findings underscore the understudied effects of community context and imply that intergroup biases manifested in incivility toward out-group members hinder organizational performance.

The relationship between expatriate job level and host country national categorization:an investigation in the UK

Using data from 493 host country nationals (HCNs) in the UK, we investigated relationships between expatriate gender, national origin, and job level, and HCN characteristics and willingness to help expatriates. Results showed that HCNs from the UK are likely to categorize expatriates as in-group or out-group members based on perceived values similarity, ethnocentrism, and collectivism. This categorization is also likely to affect HCN willingness to provide role information and social support to expatriates. Overall, our results suggest that HCNs would be more likely to provide role-related information to subordinates and peers than supervisors, and social support to male peers regardless of their nationality (i.e. USA vs. India). The analysis contributes to the fields of expatriate management, social categorization, and international human resource management. It also has key messages for multinational companies regarding the development of efficient expatriate management systems. © 2011 Taylor & Francis.

A influência da relevância social no viés de grupo

Behaviors found in every culture, general human tendencies, are knew in Evolutionary Psychology as evolved psychological mechanisms. Those behaviors date back the Environment of Evolutionary Adaptedness, and a well know example of such behavior is the group bias (or intergroup bias). This bias consists of recognizing members of your own group and favor them, while disregarding or even harming outsiders. This behavior was and still is extensively studies, among the most important conclusions about this phenomenon is the Minimal Groups Paradigm, in which it was discovered that the group bias could trigger even when the groupings were done in following very arbitrary criteria. In the current study, our goal was to test if the participants, when playing an economic game, would behave in a similar fashion under a minimal group situation and real groups, with social meaning. With this in mind we made two experimental conditions, a Low Social Meaning one (LSM) where the groups were represented by letters (H, B, O and Y) in which participants would be ramdomly assorted to each group; and the High Social Meaning condition (HSM) in which religion was used as a group marker, containing the two most dominating religious groups in Brazil, catholic and evangelic, another group containing all the other affiliations e the fourth and last group representing atheists and agnostics. The ratio of donations in-group/out-group was roughly the same across both conditions. However, the amount of wafers donated to ingroup was significantly bigger in the HSM condition. By verifying which aspects of the individual best predicted the observed group bias, we discovered that the in-group Entitativity perception as well as the Group Identification were the most relevant variables, however, only in the HSM condition. Simultaneously, by verifying the generosity, biased or not, we observed that the agreeableness personality factor was the only variable able to predict it, and only in the LSM condition. We conclude that our generosity, or the lack of it, is for most part defined by our personality, the Agreeableness factor in particular. But this very generosity can be biased by the social meaning of the involved groups and that, if the social meaning is big enough, even people who, thanks to their personality, normally wouldn’t show generosity, are able to do so when the receiver is an in-group member.

Host country nationals' support to expatriates:an investigation in Turkey

Using data from 243 executives in Turkey, we investigate the relationship(s) between perceived values similarity, in-group/out-group categorisation, interpersonal effect and Host Country National (HCN) willingness to offer role information and social support to expatriates. Results of this study confirm that HCNs are more likely to offer support to expatriates whom they categorise as in-group, as well as to those who they perceive as holding similar values. In addition, our data suggest that Turkish HCNs are more likely to offer support to Indian expatriates as compared to expatriates from the USA, and to expatriates who are assigned to work as their supervisors rather than to expatriate subordinates. We discuss implications of our findings for multinational corporations and suggest future research ideas.

Identification with the neighborhood: Discrimination and neighborhood size

This paper analyzes the impact of a geographical social grouping (neighborhood) and its relative perceived size in the spontaneous group’s identiication level and place satisfaction, as well as the intensity of and motives for discrimination against inhabitants of other places. Two studies are presented: an experimental one using the minimal group categorization paradigm and an onsite investigation of a city neighborhood. Consistent with the predictions, the results showed that smaller neighborhoods reported higher identiication and satisfaction with the place of residence, as well as higher discrimination of other neighborhoods. In line with the optimal distinctiveness theory (ODT), the indings showed that the motivation for discrimination varies as a function of the in-group size. Thus, the members of larger groups discriminate by increasing the diferentiation between the in-group and the out-group, whereas the members of smaller groups increased the value of the in-group. Furthermore, the results were consistent with a social identity theory and ODT explanation of diverse research that shows the non-trivial nature of geographical bounded social grouping and its importance in a diverse set of contexts and its impact in inter-neighborhood relationships.

Efeito do sistema de produção nas características físico-químicas e no perfil lipídico de três músculos de suínos alentejanos

O presente trabalho tem como objetivo testar o efeito do sistema de produção com dieta rica em ácido oleico nas características zootécnicas, de carcaça, físico-químicas e no perfil lipídico dos músculos Longissimus dorsi (LD), Biceps femoris (BF) e Semimembranosus (SM) de suínos de raça Alentejana. Foram utilizados 15 animais, divididos em dois grupos, o grupo IN (n=9) foi mantido em parques individuais abertos ao exterior com 3 m2 e o grupo OUT (n=6) foi mantido numa área de 3 ha com acesso a pastagem. O grupo OUT obteve melhores performances zootécnicas. O rendimento de carcaça foi igual para ambos os grupos, e o rendimento comercial e proporção de peças nobres foi superior nos OUT. Estes obtiveram menores teores de lípidos intramusculares mas maiores teores de PUFA (ácidos gordos polinsaturados) e melhores valores para os rácios PUFA/SFA (ácido gordos saturados) e n-6/n-3. O SM foi menos afetado pelo sistema de produção; Abstract: Effect of the rearing system in the physical-chemical characteristics and the lipid profile of three muscles from Alentejano pigs The present study aims to test the effect of rearing system with oleic acid rich diet on performance, carcass and physical-chemical characteristics, and lipid profile of the muscles Longissimus dorsi (LD), Biceps femoris (BF) and Semimembranosus (SM) from Alentejano pigs. The study used 15 animals, divided into two groups. The Group IN (n = 9) was kept in individual parks open to the exterior with 3 m2, and the OUT (n = 6) was held in an area of 3 ha with access to pasture. The OUT group obtained the best performances. The carcass yield was the same for both groups, meat yield and the proportion of noble parts was superior in the OUT. These obtained lower levels of intramuscular fat but larger PUFA levels (polyunsaturated fatty acids) and best values for the ratios PUFA/SFA (saturated fatty acids) and n-6/n-3. The SM was the least affected by the rearing system

Drivers of in-group and out-of-group electronic word-of-mouth (eWOM)

Purpose – The purpose of this study is to address a recent call for additional research on electronic word-of-mouth (eWOM). In response to this call, this study draws on the social network paradigm and the uses and gratification theory (UGT) to propose and empirically test a conceptual framework of key drivers of two types of eWOM, namely in-group and out-of-group. Design/methodology/approach – The proposed model, which examines the impact of usage motivations on eWOM in-group and eWOM out-of-group, is tested in a sample of 302 internet users in Portugal. Findings – Results from the survey show that the different drivers (i.e. mood-enhancement, escapism, experiential learning and social interaction) vary in terms of their impact on the two different types of eWOM. Surprisingly, while results show a positive relationship between experiential learning and eWOM out-of-group, no relationship is found between experiential learning and eWOM in-group. Research limitations/implications – This is the first study investigating the drivers of both eWOM in-group and eWOM out-of-group. Additional research in this area will contribute to the development of a general theory of eWOM. Practical implications – By understanding the drivers of different eWOM types, this study provides guidance to marketing managers on how to allocate resources more efficiently in order to achieve the company's strategic objectives. Originality/value – No published study has investigated the determinants of these two types of eWOM. This is the first study offering empirical considerations of how the various drivers differentially impact eWOM in-group and eWOM out-of-group.

Assessing homogeneity in workplace exposure under stationary and non-stationary scenarios

In most epidemiological studies, historical monitoring data are scant and must be pooled to identify occupational groups with homogeneous exposures. Homogeneity of exposure is generally assessed in a group of workers who share a common job title or work in a common area. While published results suggest that the degree of homogeneity varies widely across job groups, less is known whether such variation differs across industrial sectors, classes of contaminants, or in the methods used to group workers. Relying upon a compilation of results presented in the literature, patterns of homogeneity among nearly 500 occupational groups of workers were evaluated on the basis of type of industry and agent. Additionally, effects of the characteristics of the sampling strategy on estimated indicators of homogeneity of exposure were assessed. ^ Exposure profiles for occupational groups of workers have typically been assessed under the assumption of stationarity, i.e., the mean exposure level and variance of the distribution that describes the underlying population of exposures are constant over time. Yet, the literature has shown that occupational exposures have declined in the last decades. This renders traditional methods for the description of exposure profiles inadequate. Thus, work was needed to develop appropriate methods to assess homogeneity for groups of workers whose exposures have changed over time. A study was carried out applying mixed effects models with a term for temporal trend to appropriately describe exposure profiles of groups of workers in the nickel-producing industry over a 20-year period. Using a sub-set of groups of nickel-exposed workers, another study was conducted to develop and apply a framework to evaluate the assumption of stationarity of the variances in the presence of systematic changes in exposure levels over time. ^

Time-differentiated target temperature management after out-of-hospital cardiac arrest: a multicentre, randomised, parallel-group, assessor-blinded clinical trial (the TTH48 trial): study protocol for a randomised controlled trial

BACKGROUND The application of therapeutic hypothermia (TH) for 12 to 24 hours following out-of-hospital cardiac arrest (OHCA) has been associated with decreased mortality and improved neurological function. However, the optimal duration of cooling is not known. We aimed to investigate whether targeted temperature management (TTM) at 33 ± 1 °C for 48 hours compared to 24 hours results in a better long-term neurological outcome. METHODS The TTH48 trial is an investigator-initiated pragmatic international trial in which patients resuscitated from OHCA are randomised to TTM at 33 ± 1 °C for either 24 or 48 hours. Inclusion criteria are: age older than 17 and below 80 years; presumed cardiac origin of arrest; and Glasgow Coma Score (GCS) <8, on admission. The primary outcome is neurological outcome at 6 months using the Cerebral Performance Category score (CPC) by an assessor blinded to treatment allocation and dichotomised to good (CPC 1-2) or poor (CPC 3-5) outcome. Secondary outcomes are: 6-month mortality, incidence of infection, bleeding and organ failure and CPC at hospital discharge, at day 28 and at day 90 following OHCA. Assuming that 50 % of the patients treated for 24 hours will have a poor outcome at 6 months, a study including 350 patients (175/arm) will have 80 % power (with a significance level of 5 %) to detect an absolute 15 % difference in primary outcome between treatment groups. A safety interim analysis was performed after the inclusion of 175 patients. DISCUSSION This is the first randomised trial to investigate the effect of the duration of TTM at 33 ± 1 °C in adult OHCA patients. We anticipate that the results of this trial will add significant knowledge regarding the management of cooling procedures in OHCA patients. TRIAL REGISTRATION NCT01689077.
