5‐Month‐Olds’ Categorization of Novel Objects: Task and Measure Dependence

To examine key parameters of the initial conditions in early category learning, two studies compared 5‐month‐olds’ object categorization between tasks involving previously unseen novel objects, and between measures within tasks. Infants in Experiment 1 participated in a visual familiarization–novelty preference (VFNP) task with two‐dimensional (2D) stimulus images. Infants provided no evidence of categorization by either their looking or their examining even though infants in previous research systematically categorized the same objects by examining when they could handle them directly. Infants in Experiment 2 participated in a VFNP task with 3D stimulus objects that allowed visual examination of objects’ 3D instantiation while denying manual contact with the objects. Under these conditions, infants demonstrated categorization by examining but not by looking. Focused examination appears to be a key component of young infants’ ability to form category representations of novel objects, and 3D instantiation appears to better engage such examining.     

The debt trap: A two-compartment train wreck… and how to avoid it

We explore sustainable paths out of a debt trap with a highly stylized two-sector differential equations model for the stocks of money in Government and Society. The model fits the data for the U.S. between 1981 and 2012 with a coefficient of correlation of 0.996. The solutions provide detailed “escape conditions” from the debt trap. A primary surplus is required. Then a government can escape its debt trap either through sustained annual monetary outflows from society to the government (taxation) but with a low initial growth rate, or through annual monetary inflows into both sectors (stimulus) with higher initial growth rate. We illustrate the use of our model with simulations which show how five indebted countries can escape their debt trap in 30 (or 70) years.     

Expressing Induced Emotions Through Free Dance Movement

The aim of this study was to examine the effect of two basic emotions, happiness and sadness, on dance movement. A total of 32 adult participants were induced to feel emotional states of either happiness or sadness and then danced intuitively to an emotionally ‘neutral’ piece of music, composed specifically for the experiment. Based on an Effort-Shape analysis of body movement, full body movement was captured and seven different movement cues were examined, in order to explore whether differences in corporeal articulations between the happy and sad condition existed. Results revealed that in the happy condition, participants moved faster, with more acceleration, and made more expanded and more impulsive movements than in the sad condition. Results are discussed with respect to possible consequences for future research on human movement.     

Reconfiguring Sovereignty in Foucauldian Genealogies of Power: The Case of English Master and Servant Law and the Dispersion and the Exercise of Sovereignty in the Modern Age

This paper is a critique and partial reconfiguration of the Foucauldian genealogy of sovereignty. Sovereignty is largely conceptualized as the antithesis of governmentality and disciplinary power in the modern age; presented as a negative case as a juridical and centralized power of interdiction and containment in the classical age. I argue that we can genealogically examine how sovereignty in the modern age underwent transformation and dispersion. My empirical focus is on how master and servant law in the eighteenth and nineteenth centuries, along with the development and transformations of local courts, led to the increasingly dispersal of sovereign power as it as practiced in specific industrial sites and regions.     

In and Out of the Ethnic Economy: A Longitudinal Analysis of Ethnic Networks and Pathways to Economic Success across Immigrant Categories1

The economic benefits to immigrants of taking jobs in ethnic workplaces, relative to the open economy, are heavily debated. We examine longitudinally differences across immigrant categories in how the choice of ethnic or non‐ethnic workplace influences the ethnic composition of social networks and how these factors impact immigrants’ economic success. Using the Longitudinal Survey of Immigrants to Canada, with data 6 months, 2 years, and 4 years after arrival, we find support for both sides of the ethnic economy debate when it is qualified by immigrant category. While economic immigrants benefit from non‐ethnic workplaces, family immigrants face economic penalties in the open economy and do better in ethnic workplaces. We argue that policies sorting immigrants into visa categories do much of the work of leading them into segmented paths of incorporation.     

Revisiting the Role of Impulsivity and Compulsivity in Problematic Sexual Behaviors

Impulsivity and compulsivity are transdiagnostic features associated with clinically relevant aspects of psychiatric disorders, including addictions. However, little research has investigated how impulsivity and compulsivity relate to hypersexuality and problematic pornography use. Thus, the aims of the present study were to investigate (a) self-reported impulsivity and compulsivity with respect to hypersexuality and problematic pornography use and (b) the similarities and possible differences between hypersexuality and problematic pornography use in these domains. Utilizing structural equation modeling (SEM) in a large community sample (N = 13,778 participants; female = 4,151, 30.1%), results indicated that impulsivity (β = .28, β = .26) and compulsivity (β = .23, β = .14) were weakly related to problematic pornography use among men and women, respectively. Impulsivity had a stronger relationship (β = .41, β = .42) with hypersexuality than did compulsivity (β = .21, β = .16) among men and women, respectively. Consequently, impulsivity and compulsivity may not contribute as substantially to problematic pornography use as some scholars have proposed. On the other hand, impulsivity might have a more prominent role in hypersexuality than in problematic pornography use. Future research should examine further social and situational factors associated with problematic pornography use.
