DS14 is more likely to measure depression rather than a personality disposition in patients with acute coronary syndrome

It has been suggested that Type D Personality is a risk factor for acute coronary syndrome (ACS) and the DS14 has been developed for its assessment. However, some of the items on the DS14 seem to evaluate depressive symptoms rather than personality features. Therefore, the present study aims to verify whether an overlap exists between the constructs of Type D Personality and depression. Three‐hundred‐and‐four consecutive patients who were both presenting their first ACS and had no history of major depression completed the Hospital Anxiety and Depression Scale (HADS) and the DS14 to assess Type D personality at baseline and have been re‐evaluated at 1, 2, 4, 6, 9 and 12‐month follow‐ups. Out of 304 subjects (80.6% males), 40 were diagnosed as depressed. An exploratory factor analysis of HADS and the DS14 in the second month revealed that four out of seven items on the depressive subscale of HADS (HADS‐D) and six out of seven items on the Negative Affectivity (NA) subscale of the DS14 segregated on the same factor. Results were verified by a Partial Confirmatory Factor Analysis performed at the twelfth month when most of the patients achieved complete remission from the depressive episode. Temporal stability was poor for NA and Type D Personality and these construct co‐vary with HADS‐D over time. Our data suggests that NA and depression are overlapping constructs, supporting the idea that the DS14 measures depressed features, rather than a personality disposition.     

Sacrifice In Hegel's Phenomenology Of Spirit

In this paper I rely on recent literature that emphasises the importance of recognition in Hegel's philosophy in order to apply the recognition-theoretic approach to the notion of sacrifice in the Phenomenology of Spirit. Firstly, I conduct a preliminary analysis by examining the general meaning of sacrifice as a form of determinate negation. Secondly, I focus on two phenomenological moments (the struggle between ‘faith’ and ‘pure insight’, and the cult) in order to answer the question, ‘Is a real (effective and unselfish) sacrifice possible?’ Finally, I argue that sacrifice should be considered as a Darstellung, and I explain the twofold connection between sacrifice and recognition. I conclude that there is no sacrifice without recognition, and the process of recognition is intrinsically sacrificial.     

Defect analysis of Fe3(Al1– x Si x ) alloys by positron-lifetime spectroscopy

The recovery behaviour of vacancy-type defects created at 1000°C in Fe₃(Al_{1– x} Si _x ) alloys has been investigated by positron-lifetime measurements in samples cooled to room temperature by water quenching, air quenching and furnace cooling. In addition, a set of samples was aged for one week at 520°C. After water quenching, measurements reveal a high concentration of thermal vacancies, and from the decrease of the average positron lifetime it is inferred that vacancy recovery is strongly composition-dependent. Greater decreases of the positron lifetime were found for Si-rich samples, suggesting diffusion enhancement as the Si concentration increases. For the Fe₃Al alloy, the retained vacancy concentration depends strongly on the cooling rate. This is related to atomic ordering and a rebuilding of the D0₃ structure.     

Solger and Hegel: Negation and Privation

Abstract

This paper has two related goals. Firstly, after briefly clarifying the theoretical core of Solger’s thought, it will analyse his metaphysics from Hegel’s point of view, emphasizing that sacrifice is, for Solger, the fundamental structure of the relationship between the finite and the Infinite. Secondly, it will investigate the main reasons behind Hegel’s criticism of Solger, showing that they have different conceptions of privation and negation and concluding that Solger and Hegel have different aims. Hegel’s aim consists in recomposing the unity of finite and infinite, whereas Solger’s thought is structured on the rupture between these two.     

Asymmetry in resting intracortical activity as a buffer to social threat

Social rejection can create powerful changes in people's brains and bodies. In the study reported here, we examined brain-based individual differences associated with buffering against cardiovascular threat responses to social rejection. Using EEG source-localization techniques, we examined differences in intracortical asymmetry. We predicted that individuals with greater left relative to right dorsolateral prefrontal activity would show a more approach-motivated response to social rejection. Eighty-four female participants were randomly assigned to one of three stressful situations: social rejection, social evaluation without rejection, or self-evaluation. Among participants assigned to the social-rejection condition, greater left relative to right prefrontal intracortical activity at baseline was associated with more adaptive cardiovascular profiles and more self-reported approach-oriented emotions. Participants in the other conditions did not show these relationships. Our data are the first to show that social context matters when attempting to link individual differences in cortical asymmetry with approach-related cardiovascular and emotional outcomes.     

Stability of mood states and biochemistry across pregnancy

Four hundred and thirty pregnant women were recruited during their second trimester of pregnancy (M=20 weeks). They were designated depressed (N=172) or nondepressed (N=258) on the Structured Clinical Interview of Depression (SCID) and the Center for Epidemiological Studies Depression scale (CES-D). They were given a second assessment when they were approximately 32 weeks gestational age. At both assessments they were given self-report measures (CES-D, the State Anxiety Inventory, and the State Anger Inventory) and provided urine samples for assays of cortisol, catecholamines (norepinephrine, epinephrine and dopamine) and serotonin. They were also given the VITAS scale for lower back pain and leg pain and a sleep disturbance scale. The stability of mood states and biochemistry across pregnancy (20 and 32 weeks) were assessed inasmuch as mood states, and biochemistry have been noted to predict prematurity and low birthweight. Significant correlations were noted for all variables except serotonin. Relationships between mood states and biochemistry were also noted but only between cortisol and depression, cortisol and anxiety, and epinephrine and anxiety. Significant stability was noted between the 20-week measures and the 32-week measures including depression, anxiety, anger, and cortisol. These were, in turn, correlated with each other and with, low back pain, leg pain, and sleep disturbance. These data suggest the stability of mood states and cortisol across pregnancy.     

Withdrawn and intrusive maternal interaction style and infant frontal EEG asymmetry shifts in infants of depressed and non-depressed mothers

The effects of maternal interaction style (intrusive/withdrawn) on the development of brain electrical activity were studied in infants of depressed and non-depressed mothers shortly after birth and again at 3-6 months of age. Infants of depressed mothers exhibited significantly greater relative right frontal EEG activation than infants of non-depressed mothers. Infants of depressed withdrawn mothers exhibited greater relative right frontal EEG activation than infants of depressed intrusive mothers. Furthermore, while infants of depressed mothers with intrusive interaction styles showed a shift towards greater relative left frontal EEG activation from birth to 3-6 months, infants of depressed mothers with withdrawn interaction styles showed a shift towards greater relative right frontal EEG activation.     

Overcoming illusory inferences in a probabilistic counterintuitive problem: The role of explicit representations

In the context of conditional probabilities, a good example of the marked discrepancy between intuition and formal reasoning is the Monty Hall dilemma (MHD). We used the MHD to study the effects of practicing the game, making explicit the underlying structure, or enhancing the representation of the different possibilities, on reaching and stating the correct answer. The results of the experiments showed that accumulated experience with the MHD increased the proportion of switching responses but did not change erroneous intuitions (Experiment 1). However, when the dilemma was presented in the form of an adversary game that made the underlying structure more explicit, more participants formed complete mental representations that enabled them to reason correctly (Experiment 2). This result was observed even without any practice with the game if the participants were encouraged to represent possibilities (Experiment 3). Therefore, in this context, correct reasoning seems to depend more on the ability to consider different possibilities than on extensive practice with the game.     

Moderate involvement in sports is related to lower depression levels among adolescents

Sports involvement has been found to be related to social and psychological well-being in Icelandic adolescents. The present study investigated whether similar relationships exist for American adolescents. A group of 89 high school seniors completed a questionnaire that gathered data on sports involvement, depression, intimacy with parents and friends, and grade point average. It was found that the moderate sports involvement group (3 to 6 hours per week) had lower depression scores than did the low sports involvement group (2 hours or less per week). The findings are discussed.     

Using token reinforcement to increase walking for adults with intellectual disabilities

The purpose of this study was to evaluate the effectiveness of token reinforcement, using an ABAB reversal design, for increasing distance walked for adults with mild to moderate intellectual disabilities at an adult day‐training center. Five participants earned tokens for walking 50‐m laps and exchanged tokens for back‐up reinforcers that had been identified through preference assessments. Token reinforcement resulted in a substantial increase from baseline in laps walked for 4 participants.
