Communication and performance in software development projects

A study of 21 software development (SD) project groups using data from 170 participants holding different positions (engineers, user representatives, project managers) and a quasi-longitudinal design shows that user participation inhibits, and standardization of methods and tools facilitates, effective SD project performance. Over and above these effects, hierarchical regression analysis reveals taskrelated internal communication to predict performance positively. Moderated regression analysis reveals that high communication facilitates project performance more strongly in late stages of the project life-cycle and when standardization of methods and tools is low. Implications for facilitating SD projects' functioning, for future research and theory building, are discussed.     

The Relationship Between Parenting Style and Children's Adjustment: The Parents' Perspective

We examined the relationship between authoritative and authoritarian parenting styles and socio-emotional adjustment in elementary school children as reported from the parents' perspective. Mothers of first through fifth graders provided information about parenting style as well as children's competencies and problem behaviors. Teachers provided ratings of children's adjustment for a subset of the participants. Results indicated that authoritative parenting was associated negatively with parent- and teacher-rated maladaptive behavior, and positively with indicators of healthy adjustment. Correlations between authoritarian parenting and adjustment were either small or non-significant. Regression analyses indicated that authoritative parenting was more predictive of children's competence than maladaptation (22% versus 10% of variance). The effects of parenting style on adjustment were not moderated by demographic variables, such as the child's gender, grade level, ethnicity, and family income.     

Reducing faking on personality tests: Testing a new faking‐mitigation procedure in a U.S. job applicant sample

Faking has remained a major concern for organizations using self‐report personality measures for selection. Scholars recenlty developed a new middle‐warning faking‐mitigation procedure. The present replication study was the first field test in the United States using 193 applicants for an entry‐level position in a New York‐based consulting firm. Results replicated most of Fan et al.'s findings including (a) the middle‐warning significantly lowered fakers' personality scores over retesting, whereas the control message had little influence on nonfakers; (b) the above warning effect carried over to personality scales that were not retested; and (c) the persistent tendency of potential fakers rising to the top of personality score distribution was weakened. In addition, applicants' perceptions were not being negatively affected by the warning.     

The Occipital Cortex in the Blind

ABSTRACT— Studying the brains of blind individuals provides a unique opportunity to investigate how the brain changes and adapts in response to afferent (input) and efferent (output) demands. We discuss evidence suggesting that regions of the brain normally associated with the processing of visual information undergo remarkable dynamic change in response to blindness. These neuroplastic changes implicate not only processing carried out by the remaining senses but also higher cognitive functions such as language and memory. A strong emphasis is placed on evidence obtained from advanced neuroimaging techniques that allow researchers to identify areas of human brain activity, as well as from lesion approaches (both reversible and irreversible) to address the functional relevance and role of these activated areas. A possible mechanism and conceptual framework for these physiological and behavioral changes is proposed.     

Conditioning against the Grain

This paper discusses counterexamples to the thesis that the probabilities of conditionals are conditional probabilities. It is argued that the discrepancy is systematic and predictable, and that conditional probabilities are crucially involved in the apparently deviant interpretations. Furthermore, the examples suggest that such conditionals have a less prominent reading on which their probability is in fact the conditional probability, and that the two readings are related by a simple step of abductive inference. Central to the proposal is a distinction between causal and purely stochastic dependence between variables.     

Impact of mood,framing, and need for cognition on decision makers' recall and confidence

This study examined the impact of mood, information framing, and need for cognition on participants' amount of recall and level of confidence in a simulated business‐decision‐making setting. No main effect was obtained for either positive or negative mood. However, in support of the congruity–incongruity hypothesis, participants who received mood‐congruent framing information (positive mood/positive framing and negative mood/negative framing) showed significantly better recall and were significantly less overconfident than those who received mood‐incongruent framing information (positive mood/negative framing and negative mood/positive framing). Yet, congruity–incongruity effects were moderated by decision makers' need for cognition and were obtained only among participants' with a lower cognitive processing requirement.

Quality of Life in Mexico: A Formative Measurement Approach

Improving quality of life for community members has become increasingly important for policy makers and society in general. This article presents the results from a representative sample of citizens from south-western Mexico. Because it is argued that quality of life indexes are formative rather than reflective, an advanced statistical method (partial least square) is used to analyze the data. The quality of life index used in the study includes the domains of health, income, work, education, safety, public services, non-governmental community services, social contact, and happiness. The results suggest that monetary-oriented indicators such as income and work are less important for respondents than domains such as happiness, social contact, or community services. However, for some of the domains, age and gender inequalities are observed.
