Body Dissatisfaction and Disordered Eating in Three Cultures: Argentina, Brazil, and the U.S.

Body dissatisfaction and associated attitudes were studied in 18–24?years old women from universities in Rosario, Santa Fe, Argentina (N?=?118), Jo?o Pessoa, Paraíba, Brazil (N?=?81), and mid-Atlantic U.S. (N?=?102). Based on anecdotal reports, theoretical concerns, and empirical studies, we expected greater body dissatisfaction and negative body attitudes in our Argentine and Brazilian samples than in the U.S. sample. Body dissatisfaction was a significant problem in all samples, but we found few differences in levels of body dissatisfaction. The Argentine and Brazilian samples scored lower than the U.S. sample on measures associated with disordered eating, experienced less pressure to be thin, and were less likely to internalize the thin body ideal. Body shame was highest in the Brazilian sample and lowest in the Argentine sample. Cultural features in Argentina and Brazil that may offer some level of protection against the thin body ideal were discussed.     

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.     

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.     

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.     

Acquisition and generalization of action effects

Three experiments studied the acquisition of action-contingent events (action effects). In a first, acquisition phase participants performed free-choice reactions with each keypress leading to the presentation of either a particular category word (e.g., animal or furniture) or an exemplar word (e.g., dog or chair). In the test phase, choice responses were made to category or exemplar words by using a word-key mapping that was either compatible or incompatible with the key-word mapping during acquisition. Compatible mapping produced better performance than incompatible mapping if the words in the practice and the test phase were the same (e.g., animal M animal), if they had a subordinate-superordinate relationship (e.g., dog M animal), belonged to the same category (e.g., dog M cat), or referred to visually related concepts (e.g., orange M circle). The findings support the assumption that action effects are acquired and integrated with the accompanying action automatically, so that perceiving the effect leads to the priming of the associated response. And, most importantly, they demonstrate that effect acquisition generalizes to other, feature-overlapping events.     

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.
