Time ordering in frontal lobe patients: a stochastic model approach

Frontal lobe patients reproduced a sequence of capital letters or abstract shapes. Immediate and delayed reproduction trials allowed the analysis of short- and long-term memory for time order by means of suitable Markov chain stochastic models. Patients were as proficient as healthy subjects on the immediate reproduction trial, thus showing spared encoding and short-term memory. They failed, instead, on the delayed trials with capital letters, but not with random shapes, suggesting that their long-term memory impairment did not depend on primary deficits for ordering, but on inability to benefit from the organisational strategies that improve the retention and retrieval in normal subjects.     

Egalitarianism and the Great Recession: A Tale of Missed Connections?

The main aim of this paper is to act as a corrective to the comparatively deafening silence of egalitarian political philosophy’s response to the Great Recession. The paper thus provides an accessible analysis of a new strand of empirical research into the causes of the crisis. This new literature, which has largely gone unnoticed by the broader philosophical community, maintains that the main driver of financial instability is income and wealth inequality coupled with income stagnation at the bottom of the income distribution. Building on this empirical research, the paper puts forward six connections between egalitarian political philosophy broadly construed, and the findings of the new literature it surveys. These connections are understood as operating in two directions: that is, they both provide reasons for egalitarians to play a larger role in debates concerning the moral aspects of financial instability, and also offer valuable insights to egalitarians to reorient their position concerning central facets of their arguments.     

Dual commitment profiles and job satisfaction among temporary agency workers

Temporary agency workers (TAWs) are an ever-increasing type of employees which establish a double work relationship with both the agency and the client organization. Within this context, the concept of dual commitment has received considerable attention in the last years. The present contribution integrates dual commitment line of research with the one adopting a person-centered approach to the study of commitment configurations, to investigate commitment profiles on a large sample of TAWs. According to Sinclair et al.'s framework, we aimed to identify TAWs' commitment profiles based on their levels of dual affective commitment (to the agency and to the client organization) and on their general continuance commitment and to investigate differences in job satisfaction among profiles. Latent profile analyses on 7225 TAWs revealed 5 distinct profiles, namely Dually Free Agents, Dually Involved, Dually Allied, (Unilaterally) Client Allied and (Unilaterally) Agency Invested. The Dually Involved profile, followed by the Dually Allied profile, had the highest level of job satisfaction, whereas the Dually Free Agent profile and the (Unilaterally) Agency Invested had the lowest. Furthermore, the (Unilaterally) Client Allied group had a higher level of job satisfaction as compared to the (Unilaterally) Agency Invested profile. Implications are discussed.     

Experimental manipulation of infant temperament affects amygdala functional connectivity

In this functional magnetic resonance imaging (fMRI) study we examined neural processing of infant faces associated with a happy or a sad temperament in nulliparous women. We experimentally manipulated adult perception of infant temperament in a probabilistic learning task. In this task, participants learned about an infant's temperament through repeated pairing of the infant face with positive or negative facial expressions and vocalizations. At the end of the task, participants were able to differentiate between “mostly sad” infants who cried often and “mostly happy” infants who laughed often. Afterwards, brain responses to neutral faces of infants with a happy or a sad temperament were measured with fMRI and compared to brain responses to neutral infants with no temperament association. Our findings show that a brief experimental manipulation of temperament can change brain responses to infant signals. We found increased amygdala connectivity with frontal regions and the visual cortex, including the occipital fusiform gyrus, during the perception of infants with a happy temperament. In addition, amygdala connectivity was positively related to the post-manipulation ratings of infant temperament, indicating that amygdala connectivity is involved in the encoding of the rewarding value of an infant with a happy temperament.
