Introduction to the special issue: Social construct within an information society

Managing Information Systems (IS) is increasingly complex, as multiple stakeholders try to communicate, act, and interact for social and business gain. Understanding and managing these complex stakeholder relations and the contingencies of successful communication among culturally diverse stakeholder groups are some of the major challenges for professional communicators in the third millennium. Such challenges have important implications for communication between user and developer groups as training and education of the users becomes more complex. In an effort to connect information system practice with communication theory, this special issue of IEEE Transactions on Professional Communication looks at information systems as social constructs of an information societ

First Do No Harm?: Tort Reform and Birth Outcomes

We examine the impact of tort reforms using U.S. birth records for 1989-2001. We make four contributions: First, we develop a model that analyzes the incentives created by specific tort reforms. Second, we assemble new data on tort reform. Third, we examine a range of outcomes. Finally, we allow for differential effects by demographic/risk group. We find that reforms of the "deep pockets rule" reduce complications of labor and C-sections, while caps on noneconomic damages increase them. Our results demonstrate there are important interactions between incentives created by tort law and other incentives facing physicians.

Traffic Congestion and Infant Health: Evidence from E-ZPass

We exploit the introduction of electronic toll collection, (E-ZPass), which greatly reduced both traffic congestion and vehicle emissions near highway toll plazas. We show that the introduction of E-ZPass reduced prematurity and low birth weight among mothers within 2km of a toll plaza by 10.8% and 11.8% respectively relative to mothers 2-10km from a toll plaza. There were no immediate changes in the characteristics of mothers or in housing prices near toll plazas that could explain these changes. The results are robust to many changes in specification and suggest that traffic congestion contributes significantly to poor health among infants.

Cut to the Bone? Hospital Takeovers and Nurse Employment Contracts

This paper uses data from the 1990s to examine changes in the wages, employment, and effort of nurses in California hospitals following takeovers by large chains. The market for nurses has been described as a classic monopsony, so that one might expect increases in firm market power to be associated with declines in wages. However, we show that if one extends the monopsony model to consider effort, or if we apply a basic contracting model to the data, then we would expect to see effects on effort rather than on wages. This prediction is bourne out by the data nurses see few declines in wages following takeovers, but see increases in the number of patients per nurse, our measure of effort. We also find that these changes are similar in the largest for-profit and non-profit chains, suggesting that market forces are more more important than institutional form.

Gender inequality and sex differences in physical fighting, physical activity, and injury among adolescents across 36 countries

Purpose: Sex differences in adolescent health are widely documented, but social explanations for these sex differences are scarce. This study examines whether societal gender inequality (i.e., men’s and women’s unequal share in political participation, decision-making power, economic participation and command over resources) relates to sex differences in adolescent physical fighting, physical activity, and injuries. Methods: National-level data on gender inequality (i.e. the United Nations Development Program’s Gender Inequality Index) were linked to health data from 71,255 15-year olds from 36 countries in the 2009/10 Health Behavior in School-aged Children (HBSC) study. Using multilevel logistic regression analyses, we tested the association between gender inequality and sex differences in health while controlling for country wealth (GDP per capita). Results: In all countries, boys reported more physical fighting, physical activity, and injuries than girls, but the magnitude of these sex differences varied greatly between countries. Societal gender inequality positively related to sex differences in all three outcomes. In more gender unequal countries, boys reported higher levels of fighting and physical activity, compared to boys in more gender equal countries. In girls, scores were consistently low for these outcomes, however injury was more common in countries with less gender inequality. Conclusions: Societal gender inequality appears to relate to sex differences in some adolescent health behaviors and may contribute to the establishment of sex differences in morbidity and mortality. To reduce inequalities in the health of future generations, public health policy should target social and cultural factors that shape perceived gender norms in young people

Diagnosis and Unnecessary Procedure Use: Evidence from C-Section

This paper develops and applies a model in which doctors have two dimensions of skill: diagnostic skill and skill performing procedures. Higher procedural skill increases the use of intensive procedures across the board, while better diagnostic skill results in fewer intensive procedures for the low risk, but more for the high risk. Deriving empirical analogues to our theoretical measures for the case of C- section, we show that improving diagnostic skill would reduce C-section rates by 15.8% among the lowest risk, and increase them by 4.7% among the high risk while improving outcomes among all women
