The Therapeutic Promise of Pluripotency and its Political use in the Italian Stem Cell Debate

Stem cell research is considered one of the most promising branches of contemporary biomedicine. The capacity to develop into almost any cell type of the mature organism—pluripotency—is associated with human embryonic stem cells (hESCs) and is regarded as having great therapeutic potential. Harvesting stem cells destroys the human embryo, however; so research on embryonic stem cells has provoked controversies. In some countries such as Italy, the use of human embryos for research and therapeutic purposes is strictly forbidden. The Italian restrictive regulation has been explained by structural–cultural factors such as religion, but a better explanation lies in the policy dramaturgies deployed in the Italian debate. It was a struggle between two research trajectories—research on hESCs and on adult stem cells—for monopoly over the most credible therapeutic promise. Each was linked to different views of the Italian social order; each was epistemically legitimized by discourses on pluripotency and on the therapeutic potential of different stem cell types. Catholic actors articulated epistemic discourses on the therapeutic promises of different stem cell sources. The battle to define the social order—between a secular and a confessional view—became a struggle between two research trajectories for monopoly over the most credible therapeutic promise. The restrictive regulatory framework resulted from successfully transforming a policy dramaturgy into a new regulatory order. Thus structural–cultural variables such as religiosity matter only through the agency of institutional actors in local political cultures.

EEG decoding of semantic category reveals distributed representations for single concepts

Achieving a clearer picture of categorial distinctions in the brain is essential for our understanding of the conceptual lexicon, but much more fine-grained investigations are required in order for this evidence to contribute to lexical research. Here we present a collection of advanced data-mining techniques that allows the category of individual concepts to be decoded from single trials of EEG data. Neural activity was recorded while participants silently named images of mammals and tools, and category could be detected in single trials with an accuracy well above chance, both when considering data from single participants, and when group-training across participants. By aggregating across all trials, single concepts could be correctly assigned to their category with an accuracy of 98%. The pattern of classifications made by the algorithm confirmed that the neural patterns identified are due to conceptual category, and not any of a series of processing-related confounds. The time intervals, frequency bands and scalp locations that proved most informative for prediction permit physiological interpretation: the widespread activation shortly after appearance of the stimulus (from 100 ms) is consistent both with accounts of multi-pass processing, and distributed representations of categories. These methods provide an alternative to fMRI for fine-grained, large-scale investigations of the conceptual lexicon.     

What is beautiful is good and more accurately understood. Physical attractiveness and accuracy in first impressions of personality

Beautiful people are seen more positively than others, but are they also seen more accurately? In a round-robin design in which previously unacquainted individuals met for 3 min, results were consistent with the "beautiful is good" stereotype: More physically attractive individuals were viewed with greater normative accuracy; that is, they were viewed more in line with the highly desirable normative profile. Notably, more physically attractive targets were viewed more in line with their unique self-reported personality traits, that is, with greater distinctive accuracy. Further analyses revealed that both positivity and accuracy were to some extent in the eye of the beholder: Perceivers' idiosyncratic impressions of a target's attractiveness were also positively related to the positivity and accuracy of impressions. Overall, people do judge a book by its cover, but a beautiful cover prompts a closer reading, leading more physically attractive people to be seen both more positively and more accurately.     

Valence specific laterality effects in free viewing conditions: the role of expectancy and gender of image

Recent research has looked at whether the expectancy of an emotion can account for subsequent valence specific laterality effects of prosodic emotion, though no research has examined this effect for facial emotion. In the study here (n=58), we investigated this issue using two tasks; an emotional face perception task and a novel word task that involved categorising positive and negative words. In the face perception task a valence specific laterality effect was found for surprise (positive) and anger (negative) faces in the control but not expectancy condition. Interestingly, lateralisation differed for face gender, revealing a left hemisphere advantage for male faces and a right hemisphere advantage for female faces. In the word task, an affective priming effect was found, with higher accuracy when valence of picture prime and word target were congruent. Target words were also responded to faster when presented to the LVF versus RVF in the expectancy but not control condition. These findings suggest that expecting an emotion influences laterality processing but that this differs in terms of the perceptual/experience dimension of the task. Further, that hemispheric processing of emotional expressions appear to differ in the gender of the image.

Resilience and the burnout-engagement model in formal caregivers of the elderly

This paper investigates the relationship between resilience and positive/negative mental aspects of psychological well-being in formal caregivers for the elderly. The sample consisted of 265 caregivers who work in different residential homes in Extremadura and Castilla y León (Spain). The instruments used included the Connor-Davidson Resilience Scale , the Maslach Burnout Inventory-General Survey and the Utrecht Work Engagement Scale. The most significant findings show that caregivers with higher levels of resilience also have higher levels of professional efficacy and job engagement (vigor, dedication and absorption) and appear to be less emotionally exhausted or cynical than caregivers with lower levels of resilience. It cannot be concluded that more resilient caregivers will not get burned out, but they develop better engagement skills. As they strengthen these personal attributes, they become less vulnerable to burnout.
