Negative affectivity,coping, immune status,and disease progression in hiv iwected individuals

Abstract

The primary goal of the study was to assess the relationship between personality dispositions, coping styles, immune markers, clinical status, and subjective somatic symptoms in a mixed sample of HIV positive individuals. Specifically, the prognostic value of psychological and immunological measures in HIV progression was emphasized. Subjects (n = 104) were recruited from a cohort of 422 HIV positive individuals enrolled in the Oslo HIV Cohort Study. The partkipants were given self-administered questionnaires assessing behavioral, psychological, and psychdal variables. Clinical assessment and immunological tests were performed at regular follow-up visits. Clinical status was assessed according to the Centers for Disurse Control criteria. The immune markers used were CD4 T cell counts, beta2-microglobulin concentration, sewn levels of HIV-1 p24 core protein, and levels of antibodies to core protein. In addition, subjective somatic symptoms were assessed.

The results showed that measure-s of negative affectivity (NA; e.g. anxiety, distress, tension) were consistently related to subjective somatic symptoms and passivedefensive coping style. However, no amistent association between NA measures and immune markers was found. Individuals who developed AIDS in the study period had significantly lower initial CD4 cell counts as well as lower scores on measures of active-pmblem related wping (e.g. Positive reappraisal, Seeking social support) and passivedefensive coping (i.e. Escape-Avoidance, Self-control).

The results suggest (1) that coping styles may merit a specific focus in future research of psychological factors and medical outcomes in HIV infection, and (2) because of associations of NA measures with symptom reports studies of the relationship between e.g. stress, depression and HIV outcome should consider these variables as confounders.     

Emotional competence and quality of life of children with asthma: The mediating effect of coping strategies

This study explored the mediating effect of coping strategies on the relationship between emotional competence (EC) and quality of life (QOL) among children with asthma. Participants were 87 children (M age?=?11.72, SD?=?2.58) with controlled and partially controlled asthma, undergoing everyday treatment. They filled in questionnaires assessing EC, coping strategies and QOL. Results showed that the association between some ECs and the QOL of children with asthma was fully mediated by two maladaptive cognitive coping strategies. Among children with asthma, a greater ability to differentiate their emotions, a reduced attention to bodily signals of emotions and a reduced analysis of their current emotional state were related to decreased engagement in two coping strategies (‘Ignoring Asthma’ and ‘Worrying about Asthma’), which in turn increased their QOL. These findings show that EC has an indirect effect on QOL through very specific coping strategies. They also emphasise the importance of screening EC in children with asthma and the importance of developing and using multidisciplinary interventions for them.     

Stable singular or negative stiffness systems in the presence of energy flux

We report stable systems which exhibit quasistatic stiffness that can be negative or tend to infinity without external constraint. They are based on coupled fields in the non-equilibrium presence of energy flux that is modulated by force. They evade thermodynamic restrictions by relaxing a restrictive assumption: equilibrium. Negative values of physical properties, including compressibility and heat capacity, are considered forbidden in classical thermodynamics; such analyses provide bounds on the stiffness and other properties of multiphase materials. Stable negative and singular stiffness is demonstrated experimentally in a piezoelectric system and in a thermoelastic granular material. Coupled fields occur naturally under a wide range of conditions and form the basis for many forms of technology including sensors, actuators, and electric coolers. Because all materials exhibit at least one coupled field effect, the concept is broadly general and is applicable to attaining extreme values of any physical property e.g. stiffness, permittivity, piezoelectricity.     

Spinoza: une lecture d'Aristote

Does (affirmative) judgement have a logical dual, negative judgement? Whether there is such a logical dualism was hotly debated at the beginning of the twentieth century. Frege argued in ‘Negation’ (1918/9) that logic can dispense with negative judgement. Frege's arguments shaped the views of later generations of analytic philosophers, but they will not have convinced such opponents as Brentano or Windelband. These philosophers believed in negative judgement for psychological, not logical, reasons. Reinach's ‘On the Theory of Negative Judgement’ (1911) spoke to the concerns of these philosophers. While Frege took the distinction between affirmative and negative judgement to be logically redundant, Reinach argued that it is the result of confusing judgement with a different mental act. In this article, I present Reinach's arguments against the ‘old logical dualism’ in context, analyse them and discuss Reinach's innovative use of the notion of focus in the theory of judgement. Recently, there has been a revival of the view that sentential negation is grounded in a prior mental act of rejection. In the final section, I argue that Reinach's analysis of rejection poses a challenge for the revivalists.     

Sex in the City: The ambiguity of female mating strategies

Abstract

The purpose of this paper is to discuss the limitations of evolutionary explanations of female mating strategies, and to present an alternative theory that accounts for the ambiguity of mating strategies throughout a woman's life. While mating strategies are considered to be discrete entities, it is clear that women's decision making in everyday life is based on mutually fused, ambiguous courses of actions. The current perspective addresses the commonality of female mating experiences while highlighting the uniqueness of each woman's mating strategy and outlines a multi-level perspective on strategies of women's reproductive decision making.     

Entropy,information and predictability of evolutionary systems

We investigate first several entropy concepts, from static to dynamic entropy. Dynamic entropy is introduced as a measure of predictability. Then the relation between entropy and information is studied. Following Wiener information is considered as a non‐physical quantity, not matter or energy. Information is understood as a binary relation between a sender and a receiver. We differentiate between bound and free information. Information can be created by selforganization, historically it is connected with the origin of life. The structure and predictability of informational strings is investigated. For example we study symbolic sequences generated by evolution, as e.g. texts. It is shown that several information carriers show criticality connected with the existence of long‐range correlations, long memory in time and historical behaviour (self‐tuned criticality). The higher order Shannon entropies and the conditional entropies (dynamical entropies and there limit) are calculated, characteristic scaling laws are found.     

Darwinian Happiness: Can the Evolutionary Perspective on Well-Being Help us Improve Society?

The concept of Darwinian Happiness was coined to help people take advantage of knowledge on how evolution has shaped the brain; as processes within this organ are the main contributors to well-being. Fortuitously, the concept has implications that may prove beneficial for society: Compassionate behavior offers more in terms of Darwinian Happiness than malicious behavior; and the probability of obtaining sustainable development may be improved by pointing out that consumption beyond sustenance is not important for well-being. It is difficult to motivate people to act against their own best interests. Darwinian Happiness offers a concept that, to some extent, combines the interests of the individual with the interests of society.     

Social Values and the Creative Ethos in the Greek Knowledge Society: A Phenomenological Analysis

Departing from Richard Florida's theory of the Creative Class, this article attempts to delineate the Greek creative ethos. The research involved in-depth interviews with knowledge and service workers in Greece. Adopting an existential view of creativity, which emphasizes the natural human inclination to create and engage with one's acts, and using valuing processes as tools to analyze workers’ discourses opens up the elements that underpin workers’ efforts to experience authenticity across life spheres and construct the meaning of work and good living. These efforts were sketched against a backdrop of adverse lived realities and intersected with anxious, alienated, and disempowered constructions of selfhood. Contrary to Florida's claims, the present article goes beyond positions of more or less creative workers and examines the various meanings of creativity underpinned by different lived realities.     

Mens sana in corpore sano: Psychotherapy with a cerebral palsy child aged nine months

This paper is the acount of the psychoanalytic understanding and treatment of a nine-month-old cerebral-palsy infant and her mother. When first seen, Abigail hung over her mother's arm, and would scream unceasingly if moved from this position. The mother-child relationship seemed to involve their sticking to each other without looking or losing contact. The mother's hidden hate, anger and resentment were communicated non-verbally and Abigail showed signs of finding it difficult or impossible to integrate experiences, given the amount of trauma she had suffered from an attempted abortion and the lack of enough experience of being loved to enable her to grow internally.

The process of assessing the internal world of the infant and her mother, and the thinking and planning of the psychotherapy that followed, are described. In order to promote the secure attachment of the mother-child dyad, and the emotional growth of both, the helping process focused on understanding both the baby's and mother's states in order to make sense of the child's inner world to the mother. Because of the acute pain this process involved for the mother, she was treated individually too, by a different therapist.     

Affect as a motivational state

Using Brehm's (1999) intensity of emotion paradigm, we investigated whether basic positive or negative affect operates like a motivational state. We focused on one of the most basic affects, the sensory affect experienced when eating food. Participants tasted a delicious chocolate truffle (Study 1) or some bitter chocolate (Study 2) and were exposed to either a weak, moderately strong, or a very strong reason for feeling an opposing-valence affect or to no reason. In line with the predictions, the affect that participants reported in response to chocolate functioned like a motivational state as its intensity was a cubic function of the importance of the reason for feeling an opposing affect. We discussed the implications of these findings for the conceptualisation of affect and consider several applications for food advertising and consumer rating research.
