Respiration and postural sway: detection of phase synchronizations and interactions

The aim of the central nervous system in upright stance is to control an intrinsically unstable plant. Internal disturbances, such as haemodynamics and respiration, constitute an endogenous threat to equilibrium. The way CNS reacts to those perturbations was studied in this work, through the analysis of summary scores taken from posturographic and pneumographic data. Signals were recorded simultaneously during trials administered on a sample population of healthy young adults, while sitting and standing and at paced and spontaneous uncontrolled breathing. The extraction of posturographic and pneumographic parameters was accompanied by the utilization of techniques for the detection of phase synchronization in bivariate data, and the extraction of an interaction index, the mutual information MI. The effects of the biomechanical condition and respiratory amplitude on MI and summary measures were tested with a two-way ANOVA. Summary scores clearly depend on posture condition. Synchronization between breath and postural sway is always present, depends on both biomechanical condition and respiratory threat, and cannot be reduced to a simple linear relation.     

Depression, self-esteem, and complex attributions for life problems

Past research has suggested that mild and moderate depression are associated with increased attributional processing and a tendency to make complex attributions involving two or more causes. The present research tested the hypothesis that depression and low self-esteem are associated with a tendency to make attributions to multiple causes when faced with life problems. The results were used to demonstrate that the tendency to make multiple attributions for specific life problems accounts for unique variance in depression and self-esteem scores, even after removing variance due to general attributional style. The findings are discussed with reference to the need for multidimensional models of attribution in depression and attributional retraining efforts to include an emphasis on individual differences in the number of multiple attributions made by people.     

Customer experience in coffee stores: A multidisciplinary Neuromarketing approach

Companies in the service retailing industry are constantly looking for strategies to provide a customer experience that improves brand perception and increases customer loyalty. This study provides a deeper understanding of customer experience in two coffee stores in Vietnam by providing a multidisciplinary approach, including a quantitative and a neuromarketing approach. Two-hundred participants participated in the study, combining mystery shopping visits with the Brand Association Reaction Time Test (BARTT). Results from the mystery shopping visits confirm the holistic concept of customer experience. Store atmosphere, employee service, drink quality, price, and previous visits significantly impact customer experience. Empirical results also confirm the impact of customer experience on loyalty. Furthermore, the BARTT analysis shows that in-store customer experience can influence customers' short-term brand perceptions. The national brand is associated with friendly, expensive, globalized, and unique, whereas the local brand revealed significant associations with clean, smells good, welcoming, and unique. From the mystery shopping results and the BARTT, we can infer that customer experience needs multi-methodological capturing of its multifaceted aspects. Our findings are relevant to researchers and practitioners seeking to understand and bolster customer experiences, justifying a multidisciplinary approach and the application of new insightful tools.     

Suicide after surgical treatment in patients with epilepsy: a meta-analytic investigation

Suicide is a major issue in surgically treated epileptic patients. A meta-analysis was performed comparing suicides in a sample of such patients and in the general population. The Index Medicus and the World Health Statistics Annual were searched to ascertain the suicide rates in the age groups indicated in the studies of epileptic patients for specific years and country. 11 studies were selected, comprising 2,425 patients, 24 of whom committed suicide. Data obtained for each study were processed together to calculate the mean number of suicides per 100,000 individuals with surgically treated epilepsy for each year. This meta-analysis shows that suicide in patients with epilepsy after surgical treatment is more frequent than in the general population. Results are discussed with particular attention to possible causative factors.     

The medical student experience with disasters and disaster response

Medical students from New York City were integrally involved in the response by health professionals to aid the families of victims of the September 11, 2001, attacks on the World Trade Center. The present study was performed to investigate the emotional impact of this involvement on medical students from the Mount Sinai School of Medicine in New York City. One hundred fifty-seven students responded to a mail survey that explored their personal and professional involvement in the disaster as well as their psychiatric symptoms in the week after the event and at the time of the survey (3.5 months after the event). Findings suggested a differential emotional impact on female students and on students involved in less supervised and more emotionally intense activities. However, involvement in the relief effort, per se, did not contribute to psychiatric symptomatology. It may have been associated with enhanced professional self-esteem among the students. These findings have implications for future planning of psychiatric response to disasters.     

Transforming animal species: the case of ‘oncomouse’

In this paper I deal with ethical implications arising from animal biotechnology. I analyse some general questions surrounding the production of transgenic animals through a specific case study: the oncomouse. In particular, I explore ethical factors involved in the production of oncomice. This is because biologists genetically modify animals’ germ cells and refuse to modify human germ cells. I will underline how the international community has thus far justified this ‘ethical difference’. The opinions here expressed are personal and do not commit the European Commission. Maurizio Salvi is member of the Scientific Staff of the Higher Institute of Philosophy, University of Leuven. Currently he is a Scientific Officer (National Expert Detached) of the European Commission, (Directorate-General XII, Science Research and Development, Directorate B.II.3) dealing with Bioethics research.     

Artificial organisms as tools for the development of psychological theory: Tolman’s lesson

In the 1930s and 1940s, Edward Tolman developed a psychological theory of spatial orientation in rats and humans. He expressed his theory as an automaton (the "schematic sowbug") or what today we would call an "artificial organism." With the technology of the day, he could not implement his model. Nonetheless, he used it to develop empirical predictions which tested with animals in the laboratory. This way of proceeding was in line with scientific practice dating back to Galileo. The way psychologists use artificial organisms in their work today breaks with this tradition. Modern "artificial organisms" are constructed a posteriori, working from experimental or ethological observations. As a result, researchers can use them to confirm a theoretical model or to simulate its operation. But they make no contribution to the actual building of models. In this paper, we try to return to Tolman's original strategy: implementing his theory of "vicarious trial and error" in a simulated robot, forecasting the robot's behavior and conducting experiments that verify or falsify these predictions.     

Church Attendance,Problems of Measurement,and Interpreting Indicators: A Study of Religious Practice in the United States, 1975–2010

Church attendance is usually measured in surveys by asking a direct question about frequency of churchgoing over a preset period of time, which is typically a year. Different studies have cast doubt over the validity of this indicator as it tends to overestimate actual attendance to a significant degree. The aim of this article is to compare data on church attendance provided by two different types of research conducted in the United States between 1975 and 2010: survey data (GSS) and data obtained from time use surveys (ATUS). This comparison has three main objectives: (1) to confirm the hypothesis that survey data tend to overestimate actual attendance; (2) to show that this overestimation is not constant over time and space, but tends to vary in an erratic and unpredictable way; and (3) to demonstrate that data provided by time use surveys are more reliable than the frequencies of churchgoing provided by traditional surveys when the objective is to identify trends in religiosity in a population.
