Increased activation in superior temporal gyri as a function of increment in phonetic features

A common assumption is that phonetic sounds initiate unique processing in the superior temporal gyri and sulci (STG/STS). The anatomical areas subserving these processes are also implicated in the processing of non-phonetic stimuli such as music instrument sounds. The differential processing of phonetic and non-phonetic sounds was investigated in this study by applying a “sound-morphing” paradigm, where the presence of phonetic features were parametrically varied, creating a step-wise transition from a non-phonetic sound into a phonetic sound. The stimuli were presented in an event-related fMRI design. The fMRI-BOLD data were analysed using parametric contrasts. The results showed a higher sensitivity for sounds containing phonetic features compared to non-phonetic sounds in the middle part of STG, and in the anterior part of the planum temporale (PT) bilaterally. Although the same areas were involved in the processing of non-phonetic sounds, a difference in activation was evident in the STG, with an increase in activation related to increment of phonetic features in the sounds. The results indicate a stimulus-driven, bottom-up process that utilizes general auditory resources in the secondary auditory cortex, depending on specific phonetic features in the sounds.     

Breaking through the loss cycle of burnout: The role of motivation

We aimed to study burnout as a process that develops over time. On the basis of the Conservation of Resources theory ( Hobfoll, 2002 ), we tested whether burnout induces a loss cycle, depleting resources, and enhancing demands. In addition, we investigated whether intrinsic job motivation and externally regulated job motivation attenuated or aggravated this loss cycle. Using a sample of 352 employees who answered online questionnaires in 2005 and 2007, we found that baseline burnout predicted future burnout that results from an increase in job demands (e.g., work overload) and a decrease in job resources (e.g., social support, information). Furthermore, external regulation aggravated the positive relationship between baseline burnout and demand accumulation. Intrinsic motivation attenuated the positive relationship between baseline burnout and resource loss. We conclude that intrinsic motivation is an important factor enabling employees to break through the negative cycle of burnout.     

Body satisfaction during pregnancy

The current study examines how body satisfaction of pregnant women compares to that of nonpregnant women. The sample included 68 pregnant and 927 nonpregnant young women who participated in a population-based longitudinal study examining eating and weight concerns in young adults. Body satisfaction was assessed using a 10-item modified version of the Body Shape Satisfaction Scale. The longitudinal design allowed for the assessment of body satisfaction among women both prior to and during their pregnancy. Mean body satisfaction was higher in pregnant women (32.6, 95% CI: 30.7-34.5) than nonpregnant women (29.6, 95% CI: 29.1-30.1) with moderate effect size 0.32, after adjusting for body satisfaction and body mass index prior to pregnancy, indicating that pregnant women experienced a significant increase in body satisfaction from the time prior to their pregnancy (p=.003) despite weight gain. These findings have important implications for clinicians delivering weight-related messages to women during pregnancy.     

Predicting proactive behaviour at work: Exploring the role of personality as an antecedent of whistleblowing behaviour

This paper reports on the role of personality as an antecedent of proactive behaviour at work in the form of whistleblowing. In the interest of triangulation, two studies were used, along with two personality measures. The results of Study 1, conducted among 503 municipality employees, show that the NEO Five‐Factor Inventory dimensions of extraversion and agreeableness are significantly associated with whistleblowing, with odds ratios of 1.13 and 0.91, respectively. The result from Study 2, conducted among a representative sample of employees, shows that the circumplex of interpersonal problems dimension domineering was significantly associated with whistleblowing, with an odds ratio of 1.66. The results suggest that personality, in the form of high extraversion and dominance and low agreeableness, do play a role as antecedents of whistleblowing.     

Multimo dal Logics of Products of Topologies

We introduce the horizontal and vertical topologies on the product of topological spaces, and study their relationship with the standard product topology. We show that the modal logic of products of topological spaces with horizontal and vertical topologies is the fusion S4 ⊕ S4. We axiomatize the modal logic of products of spaces with horizontal, vertical, and standard product topologies.We prove that both of these logics are complete for the product of rational numbers ℚ × ℚ with the appropriate topologies.

The activities of UNESCO in the area of ethics

The member states of the United Nations Educational, Scientific and Cultural Organization (UNESCO) decided in 2002 that ethics is one of the five priority areas of the organization. This article describes three categories of past and current activities in the ethics of science and technology, in particular bioethics. The first category is the global standard setting with the Universal Declaration on Bioethics and Human Rights as the most recently adopted normative instrument. The second category focuses on capacity building in order to enable member states to apply the provisions of the declarations, through, for example, the establishment of national bioethics committees, the introduction of ethics teaching programs, and drafting of legislation and guidelines. The final category of activities is awareness raising through publications, events, and conferences. The challenges and difficulties UNESCO may face in its various activities are highlighted.
