Service diversification and growth of professional service firms

This study investigates the impact of service diversification on the rate and mode of firm growth in professional service firms (PSFs). Drawing on the extant PSF literature, we identify differing views regarding the growth impact of service diversification. Specifically, some scholars suggest that the external client benefits associated with service diversification should allow PSFs to expand revenues at a rapid pace and pursue less merger and acquisition activity, whereas others imply that increased diversification can cause internal challenges with respect to learning costs, coordination and innovation that can limit the rate of revenue growth and encourage more mergers and acquisitions. We test these competing views using longitudinal data on 137 accounting firms and cross-sectional data on 125 law firms and find that service diversification is negatively associated with the rate of firm revenue growth and positively associated with the use of mergers and acquisitions.     

Infant screen exposure links to toddlers' inhibition,but not other EF constructs: A propensity score study

Technology is pervasive in homes of families with young children, despite evidence for negative associations between infant exposure to screen‐based media and cognitive development that has led the American Academy of Pediatrics (AAP) to discourage parents from exposing children under the age of 18 months to any kind of screen time (AAP, 2016). Here, we apply a propensity score matching approach to estimate relations between electronic screen‐based media use in infancy and executive function in early toddlerhood. In an international sample of 416 firstborn infants, parental report of regular exposure to screen‐based media at 4 months predicted poorer performance on a test of inhibition at 14 months, but was unrelated to either cognitive flexibility or working memory at 14 months. Results of this study are therefore consistent with the view that early exposure to screen‐based media adversely affects the development of executive function.     

Monstrosities and moral publics

Interdisciplinary scholarship on neoliberal urban governmentality has been attentive to the knowledges and techniques of government currently emerging at the interface of local state politics and invested claims of voluntary private actors such as corporate partners and philanthropic agencies. This article draws attention to the workings of the aesthetic as an epistemological grounding for the rationalization of urban rule. Specifically, I explore a Toronto, Canada-based philanthropic agency’s reliance on a mise-en-scene of urban terror to animate its own self-validated knowledges about targeted inner-suburban subjects and spaces. In their circulation and demand for public address, the agency’s graphic public service announcements, launched in 2007, herald what I argue is a moralized set of knowledges about municipal renewal that has its own normative orientations grounded in a neoliberal political rationality, and tangentially, in racialized security imperatives. I detail various dimensions of the social life of a video associated with this public service campaign targeting ‘youth at risk’, considering the ethical, political and economic valences it was expected to convey; its semiotic exchange with other images and representations of disenfranchised spaces, subjects and communities; and the publics it attempted to interpellate. Importantly, given the agency’s current standing as a prominent player in Canadian urban policy arenas, I pay analytical attention to the visual campaign as a site for the production of knowledges about proper urban citizenship and social governance, and as such, a strategic-orienting device for urban policy interventions and directives.     

Who Protests in America: An Analysis of Three Political Alternatives—Inaction,Institutionalized Politics,or Protest

Theories of social movements and collective action typically present social protest as one of three alternatives available to the individual: inaction, institutionalized political action, or protest. These political alternatives are rarely considered simultaneously nor are they modeled explicitly. In this paper we make use of survey data from a representative sample of the United States population. We employ multinomial logistic regression to determine what differentiates those who protest from those who engage only in institutionalized politics and from those who engage in no political action. We find that those who engage in social protest are similar in many respects to those who engage actively in institutionalized politics, yet education on social and political issues, participation in community organizations, and frequent church attendance increases the likelihood that individuals will engage in protest relative to institutionalized politics.     

The Relationship Between Divorce and Children with AD/HD of Different Subtypes and Comorbidity: Results from a Clinically Referred Sample

This study investigated the relationship between divorce and the symptom profile of children with attention deficit/hyperactivity disorder (AD/HD). The files of 1,201 children from a pediatric practice in Sydney, Australia were used in this study. Children were aged 6 to 18 years, and were diagnosed with either the inattentive or combined type of AD/HD. Results show that 213 children had parents who were divorced. Children with the combined type, and especially boys with comorbid conduct disorder/oppositional defiant disorder (CD/ODD) were more common in the divorced group, and children of the inattentive type with comorbid learning disabilities were overrepresented in nondivorced families. Results suggest that divorce is associated with disruptive behavior patterns in children with AD/HD. The importance of including marital status as an important correlate in AD/HD treatment outcomes is discussed.     

“Did I just do that?”—Six-month-olds learn the contingency between their vocalizations and a visual reward in 5 minutes

It has been shown that infants can increase or modify a motorically available behavior such as sucking, kicking, arm waving, etc., in response to a positive visual reinforcement (e.g., DeCasper & Fifer, 1980; Millar, 1990; Rochat & Striano, 1999; Rovee-Collier, 1997; Watson & Ramey, 1972). We tested infants to determine if they would also change their vocal behavior in response to contingent feedback, which lacks the social, emotional, and auditory modeling typical of parent-child interaction. Here, we show that in a single five-minute session infants increase the rate of their vocalizations in order to control the appearance of colorful shapes on an iPad screen. This is the first experimental study to demonstrate that infants can rapidly learn to increase their vocalizations, when given positive reinforcement with no social element. This work sets the foundations for future studies into the causal relationship between the number of early vocalizations and the onset of words. In addition, there are potential clinical applications for reinforcing vocal practice in infant populations who are at risk for poor language skills.     

A Different Take on the Big Bang Theory: Examining the Influence of Asperger Traits on the Perception and Attributional Confidence of a Fictional TV Character Portraying Characteristics of Asperger Syndrome

Research shows that media figures can influence the construction of one’s personal and social identity. However, there are few studies that examine representations of stigmatized groups with developmental disorders, such as those with autism spectrum disorders. This research examines the effect of a viewer’s scores on the autism quotient (AQ) and their relationship with homophily and attributional confidence towards Sheldon on The Big Bang Theory, who is suspected of having Asperger’s syndrome (AS). Guided by uncertainty reduction theory the results indicated a positive relationship between the dimensions of the AQ and homophily with Sheldon, and a positive relationship between higher scores on the AQ and attributional confidence towards Sheldon. The implications of identification with fictional television characters for individuals with AS, and the application of the AQ in future research are discussed relative to the current findings.
