The Number of Times an Anonymous Rule Violates Independence in the 3 × 3 Case

If an anonymous rule f always outputs a transitive relation and satisfies Pareto, then, by Arrow’s theorem, f violates the condition of independence. We give lower and upper bounds for the number of times an anonymous rule violates independence in the case of three alternatives and three voters.     

Early Child Care and the School Readiness of Children from Mexican Immigrant Families1

Combining conceptual models from immigration and educational research, this study investigated whether a normative antecedent to the transition to formal schooling in the contemporary U.S. – early child care – links Mexican immigrant status to various aspects of school readiness. Regression models with nationally representative data revealed that children from Mexican immigrant families were overrepresented in parental care and underrepresented in center‐based care compared to their native peers from other race/ethnic populations, which helped to explain a significant but small portion of their generally lower rates of both math achievement and externalizing symptoms in kindergarten. This mediating role of early child care, however, paled in comparison to family socioeconomic circumstances.     

Effects of segmentation patterns on the perception of deception

Subjects viewed videotapes of truthful and deceptive messages. Channels presented were either face or body with or without speech. Subjects were instructed to segment each message into either large, medium, or small units; following the segmentation of a message, subjects rated its truthfulness. Results showed that subjects who organized the behavior into small units perceived the messages as more truthful than those who organized the behavior into either medium or large units. In addition, when speech was available, accuracy of lie detection was highest when the behavior was segmented into medium units; when speech was not available, accuracy of lie detection was highest when the behavior was segmented into small units. The effects of observation set on the perception of deception were discussed.     

Markov bridges and enlarged filtrations

The semimartingale decomposition of a Markov chain, whose value at some future time is known, is obtained by considering an enlarged filtration.     

A Holland Perspective on the U.S. Workforce From 1960 to 2000

The authors analyze civilian occupations and employment data collected by the U.S. Census Bureau in 1960, 1970, 1980, 1990, and 2000 with respect to 6 kinds of work (Holland's RIASEC [Realistic, Investigative, Artistic, Social, Enterprising, Conventional] classification), employment, and gender. For the 1990 and 2000 censuses, kinds of work, gender, and income are analyzed, and for the 2000 census, kinds of work, age, and gender are examined. Past employment trends developed from census data are further analyzed with respect to Bureau of Labor Statistics employment projections through 2012. Implications for further research, employment policy, and career services are offered.     

Network Neutrality Versus Paid Prioritization: Analyzing the Impact on Content Innovation

We examine the link between network neutrality (NN) and content innovation on the Internet by comparing the impact of NN and packet discrimination (PD) regimes on content innovation. We do this in the context of a two‐sided market model that simultaneously considers content provider (CP) and consumer decisions concerning market entry and participation while taking into account consumers’ response to network congestion. We find that content innovation flourishes under NN to a greater degree than under PD due to two effects we uncover: the generation of what we call a pro bono innovation zone in which CPs are able to enter the market without contributing to network provider profits; and the cross‐side congestion effect, a negative network externality wherein higher broadband market coverage levels result in greater congestion for CPs, and increased content results in greater congestion for consumers, taking into account consumers’ strategic response to network congestion. These results have important implications for current public policy debates regarding the Federal Communications Commission's Open Internet Rules.     

Complex Interrelations of Trait Vulnerabilities in Mothers and their Infants

Despite the developmental and clinical relevance of this area of inquiry, no studies have examined the interrelations of trait vulnerabilities in the affective, behavioral, and interpersonal domains between mothers and their infants. Thus, this study examined the interrelations of three trait vulnerabilities (i.e., negative affective intensity, impulsivity, and insecure attachment) between mothers and their 12‐ to 23‐month‐old infants, focusing in particular on the unique and interactive influence of these maternal trait vulnerabilities on the expression of and precursors to these traits in their infants. Mother–infant dyads (N = 101) completed several laboratory procedures, and mothers reported on their own and their infants' expressions of the trait vulnerabilities of interest. Findings from this study provide preliminary evidence for intergenerational relations between these traits and suggest that it is the confluence of trait vulnerabilities in mothers that relates to the early expression of some of these traits in infants.
