How negotiators get to yes: Predicting the constellation of strategies used across cultures to negotiate conflict.

Individualism, hierarchy, polychronicity, and explicit-contracting values explain why managers from Germany, Japan, and the United States use a different mix of strategies to negotiate workplace conflict. Hypotheses extend prior research in showing that conflict behavior is multiply determined and that each culture uses a variety of interests, regulations, and power-based conflict management strategies. Results of actual (rather than survey-based) conflict resolution behavior suggest several fruitful avenues for future research, including examining the inferred meaning of negotiation arguments, analyzing interaction effects of cultural value dimensions, studying the effectiveness of different strategies across cultures, and examining whether strategic adjustments are made during intercultural conflict management.

Exploring the role of individual differences in the prediction of workplace aggression.

This study investigates the relationship between individual differences and the incidence of workplace aggression in a sample of employees from a transportation company and a public school system. Hierarchical multiple regression analysis indicated that measures of trait anger, attribution style, negative affectivity, attitudes toward revenge, self-control, and previous exposure to aggressive cultures accounted for 62% of the variance in the participants' self-reported incidence of workplace aggression. Further research on workplace aggression is advocated, focusing on the role of individual differences and their interactions with organizational and group-level variables.

Effects of variable lighting intensities and colour temperatures on sulphatoxymelatonin and subjective mood in an experimental office workplace

Workplace illumination is of paramount importance in determining the employee's productivity and well-being. Moreover, light exerts non-visual effects with respect to biological rhythms. In this study, we investigated the impact of different lighting conditions (500-1800 lx, 6500 K; 500 lx, 4000 K) on sulphatoxymelatonin (aMT6-s) and subjective mood in an experimental office accommodation. Urinary aMT6-s concentrations were significantly decreased at all days of the experiment in both lights. On day 3, differences between aMT6-s concentrations in specimen collected at 05:00 p.m. and at 09:00 a.m. were significantly higher under variable lighting conditions. Analyses of a mood rating inventory revealed a benefit of variable light with respect to the dimensions of "Activity", while "Deactivation" and "Fatigue" were increased in regular light on day 1. "Activity", "Concentration", and "Deactivation" changed in opposite directions when comparing variable with regular illumination on two consecutive days. In conclusion, variable light exerts a potential advantage in indoor office accommodations with respect to subjective mood, although no unequivocal differences in the profile of aMT6-s were found as compared to regular light.     

Analysis of integrated circuit fault data using generalized linear models

Fault data for integrated circuits manufactured on silicon wafers are usually presented using wafer maps to indicate the spatial distribution of defects. This paper shows how this type of spatial data can be analyzed under the framework of generalized linear models. This provides a systematic method for monitoring the quality of a manufacturing process, and identifying fault sources with assignable causes that may possibly be eliminated with process improvement as a result. We consider models that account for different spatial patterns and, in particular, the observed phenomenon that the faults are distributed non‐uniformly across the wafer. Furthermore, we demonstrate how designed experiments can be used in optimizing the setting of important process parameters. Copyright © 2000 John Wiley & Sons, Ltd.     

Language exclusion and the consequences of perceived ostracism in the workplace.

The current research examined the impact of workplace ostracism on work-related attitudes and behaviors. Participants read a vignette describing a series of workplace interactions between the participant and two coworkers. During the interactions, participants were included in a group discussion, ostracized by coworkers in English or ostracized in Spanish. Consistent with predictions, ostracized participants reported lower levels of organizational commitment and organizational citizenship behaviors than included participants. Ostracism by language resulted in lower work group commitment and higher levels of symbolic threat compared with included participants and those ostracized in English. Increased prejudice was also reported by participants exposed to language ostracism. Results are discussed in terms of their implications for general attitudinal processes and employee-related work attitudes and behaviors.

The fit and implementation of sexual harassment law to workplace evaluations.

Three studies used videotaped harassment complaints to examine the impact of legal standards on the evaluation of social-sexual conduct at work. Study 1 demonstrated that without legal instructions, college students' judgment strategies were highly variable. Study 2 compared 2 current legal standards, the "severity or pervasiveness test" and a proposed utilitarian alternative (i.e., the rational woman approach). Undergraduate participants taking the perspective of the complainant were more sensitive to offensive conduct than were those adopting an objective perspective. Although the utilitarian alternative further increased sensitivity on some measures, it failed to produce a principled judgment strategy. Finally, Study 3 examined the kinds of errors that full-time workers make when applying the "severity or pervasiveness" test to examine more closely the sensitivity of the subjective approach.

Assessing Variation in Development Effort Consistency Using a Data Source with Missing Data

In this study the authors analyse the International Software Benchmarking Standards Group data repository, Release 8.0. The data repository comprises project data from several different companies. However, the repository exhibits missing data, which must be handled in an appropriate manner, otherwise inferences may be made that are biased and misleading. The authors re-examine a statistical model that explained about 62% of the variability in actual software development effort (Summary Work Effort) which was conditioned on a sample from the repository of 339 observations. This model exhibited covariates Adjusted Function Points and Maximum Team Size and dependence on Language Type (which includes categories 2nd, 3rd, 4th Generation Languages and Application Program Generators) and Development Type (enhancement, new development and re-development). The authors now use Bayesian inference and the Bayesian statistical simulation program, BUGS, to impute missing data avoiding deletion of observations with missing Maximum Team size and increasing sample size to 616. Providing that by imputing data distributional biases are not introduced, the accuracy of inferences made from models that fit the data will increase. As a consequence of imputation, models that fit the data and explain about 59% of the variability in actual effort are identified. These models enable new inferences to be made about Language Type and Development Type. The sensitivity of the inferences to alternative distributions for imputing missing data is also considered. Furthermore, the authors contemplate the impact of these distributions on the explained variability of actual effort and show how valid effort estimates can be derived to improve estimate consistency.
