“Primary Relations” In a New Foundational Axiomatic Framework

The new system of axioms we propose is based on the foundational theory of De Giorgi et al. Scuola Normale Superiore di Pisa, Preprints di Matematica 26: 1 (1996) slightly modified. In that paper (which is dedicated to a new axiomatic framework for mathematics, informatics and logic) the authors use two kinds of primitive notions: relations and qualities. Since their system is based on the distribution paradigm, they start from distinction. We propose to shift the perspective and to start from unity and then from within unity to pass to distinction; to this end we apply ideas of Lesniewski, Nijhoff International Philosophy Series 44 (1992). We introduce only one kind of entity as a primitive notion, namely relations, and treat qualities as articulations of relations. The new concept of “primary relation” permits the introduction of a dynamic, non-standard form of identity, which we hope will find application in various fields where self-referential structures are required.     

Syntactic component in language responsible cognitive structure: Neurological evidence

From the results of a broad ranging comprehension test, a hierarchy of difficulty emerged that is shared by the two groups of aphasics (Broca's and Wernicke's aphasics) and by the control group of normal subjects. The parallelism has been interpreted as a confirmation of the hypothesis that syntactic competence is not inaccessible either in Wernicke's or in Broca's aphasia. The Minimal Distance Principle, as a relevant recognition principle, has been studied, and although not confirmed by the scores has been brought to the fore both by the correlations between the variables under study and by the correlations with the concomitant variables of age and level of education.     

Decision making and job satisfaction among youth workers in community-based agencies

Sixty-four counselors and 32 alternative school teachers in 13 grass-roots agencies reported on levels of participation, influence, and competence in making clinical and administrative decisions. The data supported predictions that (a) professionals would report greater decision-making opportunities and abilities than nonprofessionals, and (b) that workers in general would report higher levels of participation, influence, and competence in clinical than in administrative domains, and higher levels of competence than influence in both domains. However, regression analyses testing the effects of the decision-making variables on different aspects of job satisfaction did not support predicted interactions among participation, influence, and competence. Rather, decision-making involvements had positive effects and decision-making abilities had negative effects on worker morale. The discussion high-lights the need for further research to identify the underlying processes involved in the observed relationships.     

Context fear learning specifically activates distinct populations of neurons in amygdala and hypothalamus

The identity and distribution of neurons that are involved in any learning or memory event is not known. In previous studies, we identified a discrete population of neurons in the lateral amygdala that show learning-specific activation of a c-fos-regulated transgene following context fear conditioning. Here, we have extended these studies to look throughout the amygdala for learning-specific activation. We identified two further neuronal populations, in the amygdalo-striatal transition area and medial amygdala, that show learning-specific activation. We also identified a population of hypothalamic neurons that show strong learning-specific activation. In addition, we asked whether these neurons are activated following recall of fear-conditioning memory. None of the populations of neurons we identified showed significant memory-recall-related activation. These findings suggest that a series of discrete populations of neurons are involved in fear learning in amygdala and hypothalamus. The lack of reactivation during memory recall suggests that these neurons either do not undergo substantial change following recall, or that c-fos is not involved in any such activation and change.     

Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents,and 13 islands

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize sex differences in the evolved design of short-term mating provide the most compelling account of these robust empirical findings.     

Neuropsychological disorders indicative of postresuscitation encephalopaty in rats

The aim of this research was to study the effect of 12-minute clinical death on innate and acquired behavior, biogenic amine concentration, and the composition and quantity of neural populations in specific brain regions of white rats. The study shows that in animals during the postresuscitation period with formal restoration of neurological status, there are changes in emotional reactivity, orientation-exploration reactions, impairment of learning and memory, decrease in exercise tolerance and pain sensitivity. These processes are accompanied by alterations in serotonin and norepinephrine levels in the frontal cerebral cortex, dopamine and serotonin levels in the striatum, certain biochemical indices in blood plasma and neural loss in the CA1 sector of the hippocampus and lateral portions of the cerebellum.     

Cues and concerns by patients in medical consultations: a literature review

The aim of the current article is to review the peer-reviewed research literature on cues and concerns published between 1975 and 2006. To be included, articles had to report observational studies based on patient-physician consultations and report findings on patient expressions of cues and/or concerns. Quantitative and qualitative studies from different medical settings were considered. Fifty-eight original articles based on the analysis of audio- or videotaped medical consultations were tracked down. Definition of cues and concerns and methodological approaches differed widely. Physicians missed most cues and concerns and adopted behaviors that discouraged disclosure. Communication training improved the detection of cues and concerns. Future research progress would require different methodological approaches more appropriate for studying verbal interactions and the complexity of the various levels that influence interactions.     

Stress as a trigger for headaches: relationship between exposure and sensitivity

This study investigated the relationship between length of exposure to a stressor and capacity of the stressor to elicit head pain. Some 127 participants, 93 of whom suffered from regular headaches, were randomly assigned to five experimental conditions, defined by length of exposure to a stressor. Participants attended a single laboratory session divided into three phases: pre-intervention test, intervention and post-intervention test. The main finding was a significant cubic trend between length of exposure to the stressor and ratings of head pain. This trend indicated that very short exposure to the stressor increased sensitivity, whilst longer exposure decreased sensitivity, but even longer exposure increased sensitivity. These results build on earlier studies that suggest the traditional clinical advice to headache sufferers, that the best way to prevent headaches is to avoid the triggers, runs the risk of establishing an insidious sensitization process, thereby increasing headache frequency.
