Once More about Boesch’s Ontological Predication in Focus

In this article I address some more aspects regarding Boesch’s ontological predication aiming to clarify mistaken comprehensions as appeared in Perez-Campos” (2017) detailed work on my former paper about this issue (Simão 2016b). With this purpose, the following three aspects will be approached: the philosophical roots of my former proposal; the place of Boesch’s symbolic action theory in that proposal and the relevance of this discussion for the relationship between ontology and psychology.     

Effects of repetitive stress during the acute phase of Trypanosoma cruzi infection on chronic Chagas' disease in rats

The effect of repetitive stress during acute infection with Trypanosoma cruzi (T. cruzi) on the chronic phase of ensuing Chagas' disease was the focus of this investigation. The aim of this study was to evaluate in Wistar rats the influence of repetitive stress during the acute phase of infection (7 days) with the Y strain of T. cruzi on the chronic phase of the infection (at 180 days). Exposure to ether vapor for 1 min twice a day was used as a stressor. Repetitive stress enhanced the number of circulating parasites and cardiac tissue disorganization, from a moderate to a severe diffuse mononuclear inflammatory process and the presence of amastigote burden in the cardiac fibers. Immunological parameters revealed that repetitive stress triggered a reduced concanavalin A induced splenocyte proliferation in vitro with major effects on the late chronic phase. Serum interleukin-12 concentration decreased in both stressed and infected rats in the early phase of infection although it was higher on 180 days post-infection. These results suggest that repetitive stress can markedly impair the host's immune system and enhance the pathological process during the chronic phase of Chagas' disease.     

« Porosité » entre travail et vie privée,conflits et aménagements : une étude comparative de deux populations de femmes

At present, little research has been done regarding the links between work and private life from the standpoint of subjective perceptions. The authors present a qualitative research focused on this issue involving women working in the fields of health and management. The content analysis revealed a double dynamic implying autonomy as well as “permeability” between the two worlds. Three subjective dimensions define this paradoxical movement: “dynamics in social relations”, the “subjective function of the body”, and the “perception of a certain mastery”. Outcomes show how psychological conflict can play an essential role in the personalization process. This was described by participants in terms of satisfaction, yet only under certain conditions.     

Customer Satisfaction and Switching Barriers: Effects on Repurchase Intentions,Positive Recommendations,and Price Tolerance1

The current article attempts to extend previous research by testing the effects of customer satisfaction and 2 types of switching barriers—negative and positive—on key manifestations of attitudinal loyalty (repurchase intentions, positive recommendations, and price tolerance). The work also studies whether the effect of customer satisfaction is linear or nonlinear. Finally, the paper analyzes whether switching barriers moderate the relative strength of the customer satisfaction/attitudinal loyalty relation. To this end, a total of 554 private mobile‐phone customers were surveyed. The distinction between negative and positive switching barriers is important to draw theoretical and managerial implications.     

Morphological priming by itself: A study of Portuguese conjugations

Does the language processing system make use of abstract grammatical categories and representations that are not directly visible from the surface form of a linguistic expression? This study examines stem-formation processes and conjugation classes, a case of ‘pure’ morphology that provides insight into the role of grammatical structure in language processing. We report results from a cross-modal priming experiment examining 1st and 3rd conjugation verb forms in Portuguese. Although items were closely matched with respect to a range of non-morphological factors, distinct priming patterns were found for 1st and 3rd conjugation stems. We attribute the observed priming patterns to different representations of conjugational stems, combinatorial morphologically structured ones for 1st conjugation and unanalyzed morphologically unstructured ones for 3rd conjugation stems. Our findings underline the importance of morphology for language comprehension indicating that morphological analysis goes beyond the identification of grammatical morphemes.     

Multiracial Congregations: An Analysis of Their Development and a Typology

Although the overwhelming majority of religious congregations consist of members who share the same racial background, there are a significant number of multiracial congregations in the United States. We begin with an analysis of why most congregations remain uniracial despite racial integration in other institutions. Then, based on our two-year national study, we examine the key variables underlying the development of multiracial congregations. Specifically, we consider the primary impetus for change and the source of racial diversification. Based on the analysis of how some congregations have become multiracial, we present a typology of multiracial congregations. We find seven main types. It is our hope that the typology and analysis will illuminate the effects of racial diversity on the life cycle of congregations and serve as a useful framework to guide future studies of multiracial congregations. Ultimately, we intend this article to facilitate the development of formal theory and research on the genesis and sustainability of multiracial congregations. To that end, we conclude the article by offering hypotheses suggested by the typology and its underlying causes.     

An inhibitory within-compound association attenuates overshadowing

According to the comparator hypothesis (Miller & Matzel, 1988), cue competition depends on the association between a target stimulus (X) and a competing cue (e.g., an overshadowing cue [A]). Thus, it was expected that overshadowing would be reduced by establishing an inhibitory-like relationship between X and A before compound conditioning. In three lever press suppression experiments with rats, this expectation was supported. Experiment 1 showed that establishing an inhibitory X-A relationship reduced overshadowing. In Experiment 2, degrading the inhibitory-like relationship before conditioning allowed reinforced AX compound trials to result in overshadowing. Experiment 3 replicated the results of Experiment 2 when the inhibitory relationship was degraded after compound conditioning. The results support the view that within-compound associations are necessary not only for retrospective revaluation, but also for conventional cue competition.     

Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.     

Group communication and decision-making strategies

In daily life, people frequently make inferences about current and future states of the world. Most of these inferences are not made individually, but by exchanging information about which strategies could be used with other people. In an experiment, we analyzed whether exchanging information socially increased the probability of selecting the most adaptive strategy. In our experiment, take-the-best (TTB; Gigerenzer & Goldstein, 1996), a simple heuristic that employs one-reason decision making, achieved the highest payoff. Results showed that the fit of TTB increased substantially across trial blocks when participants were allowed to exchange information with other group members. In contrast, when participants made inferences individually, they did not select the most adaptive strategy even after seven trial blocks. Overall, our results support the hypothesis that group communication increases the likelihood that participants select the most adaptive strategy for making inferences.
