Clarifying The Links Between Perceived Emotional Intelligence and Well-Being in Older People: Pathways Through Perceived Social Support from Family and Friends

Applied Research in Quality of Life - Although emotional intelligence (EI) and social support are important predictors of well-being in adolescents and adults, there has been little research on...     

Experimental results of affective valence and arousal to avatar's facial expressions.

The objectives of this study were to propose a method of presenting dynamic facial expressions to experimental subjects, in order to investigate human perception of avatar's facial expressions of different levels of emotional intensity. The investigation concerned how perception varies according to the strength of facial expression, as well as according to an avatar's gender. To accomplish these goals, we generated a male and a female virtual avatar with five levels of intensity of happiness and anger using a morphing technique. We then recruited 16 normal healthy subjects and measured each subject's emotional reaction by scoring affective arousal and valence after showing them the avatar's face. Through this study, we were able to investigate human perceptual characteristics evoked by male and female avatars' graduated facial expressions of happiness and anger. In addition, we were able to identify that a virtual avatar's facial expression could affect human emotion in different ways according to the avatar's gender and the intensity of its facial expressions. However, we could also see that virtual faces have some limitations because they are not real, so subjects recognized the expressions well, but were not influenced to the same extent. Although a virtual avatar has some limitations in conveying its emotion using facial expressions, this study is significant in that it shows that a new potential exists to use or manipulate emotional intensity by controlling a virtual avatar's facial expression linearly using a morphing technique. Therefore, it is predicted that this technique may be used for assessing emotional characteristics of humans, and may be of particular benefit for work with people with emotional disorders through a presentation of dynamic expression of various emotional intensities.     

An encompassing framework for Paraconsistent Logic Programs

We propose a framework which extends Antitonic Logic Programs [Damásio and Pereira, in: Proc. 6th Int. Conf. on Logic Programming and Nonmonotonic Reasoning, Springer, 2001, p. 748] to an arbitrary complete bilattice of truth-values, where belief and doubt are explicitly represented. Inspired by Ginsberg and Fitting's bilattice approaches, this framework allows a precise definition of important operators found in logic programming, such as explicit and default negation. In particular, it leads to a natural semantical integration of explicit and default negation through the Coherence Principle [Pereira and Alferes, in: European Conference on Artificial Intelligence, 1992, p. 102], according to which explicit negation entails default negation. We then define Coherent Answer Sets, and the Paraconsistent Well-founded Model semantics, generalizing many paraconsistent semantics for logic programs. In particular, Paraconsistent Well-Founded Semantics with eXplicit negation (WFSX_p) [Alferes et al., J. Automated Reas. 14 (1) (1995) 93–147; Damásio, PhD thesis, 1996]. The framework is an extension of Antitonic Logic Programs for most cases, and is general enough to capture Probabilistic Deductive Databases, Possibilistic Logic Programming, Hybrid Probabilistic Logic Programs, and Fuzzy Logic Programming. Thus, we have a powerful mathematical formalism for dealing simultaneously with default, paraconsistency, and uncertainty reasoning. Results are provided about how our semantical framework deals with inconsistent information and with its propagation by the rules of the program.     

Stress in Academic Life: Work Characteristics as Predictors of Student Well-being and Performance

La relation entre les caractéristiques du travail, le bien-être des étudiants et la performance a étéévaluée à partir du modèle de Karasck & Theorell ≪Travail, exigences, contrôle, soutien≫ (1990). Un échantillon d'étudiants portugais ( N = 825) a répondu à un questionnaire comprenant des mesures du contrôle et des exigences du travail universitaire, du soutien des pairs, de la satisfaction relative à la vie universitaire, de l'anxiété/dépression et des résultats aux examens. Il apparut, comme dans d'aures contextes de travail, que la satisfaction des étudiants pour ce qui est de la vie universitaire, ainsi que les niveaux d'anxiété/dépression étaient fortement dépendants de leur perception des caractéristiques du travail. Les niveaux de satisfaction ont un effet direct sur la performance et agissent sur la relation entre la maîtrise du travail universitaire et la performance.
The relationship between work characteristics, student well-being and performance was assessed, based upon Karasek and Theorell's (1990 ) Job Demands–Control–Support model. A sample of Portuguese university students ( N = 825) answered a questionnaire comprising measures of academic work demands and control, peer support, satisfaction with academic life, anxiety/depression and academic performance. Results suggested that, similar to other work contexts, student satisfaction with academic life and anxiety/depression levels are strongly dependent on their perceptions of work characteristics. Levels of satisfaction have a direct impact on student performance and mediate the relationship between academic work control and performance.     

WHOM TO BLAME FOR THE CHARGE OF SECULARIZATION?

Abstract. In the last century science and technology have been viewed as guilty of contributing to the modern secularization process and also to a crisis in religion. The extent of this influence is less clear today: while technology is stronger, and an easy target for any kind of social and cultural criticism, science seems weaker than it used to. The aim of this commentary is to examine in a critical way the arguments for and against scientific and technological involvement in the crisis religion faces today. In the end, a revision of the future of religion is called into question, especially in the light of a more “technological theology.”     

The effects of acoustic mismatch and selective listening on repetition deafness

Previous research (i.e., M. Miller & D. O. MacKay, 1994, 1996) has suggested that repetition deafness (RD), like repetition blindness, is robust to physical identity and that it consists in a failure to recall specifically the 2nd of the 2 critical targets (C1 and C2). However, some confounds due to memory load and response biases make available evidence inconclusive. Experiment 1 provided a strong test of RD between physically mismatching stimuli using a low memory load methodology. In Experiment 2, the same presentation method was combined with a selective recall task to find that RD is specific of C2. Experiments 3A and 3B showed, through an attentional manipulation, that RD is eliminated when people can successfully ignore C1 but not otherwise. It is argued that present data favor a perceptual interpretation of the RD. Furthermore, the present results support the hypothesis of recognition failure as opposed to the alternative token individuation failure hypothesis.     

Risky decision making across three arenas of choice: are younger and older adults differently susceptible to framing effects?

In the present study, the authors investigated the effects of framing of options on risky decision making in groups of younger adults (M = 23.8 years, n = 192) and older adults (M = 69.1 years, n = 192). The participants were assigned to one of three scenarios varying in the goods at stake (human lives, paintings, money). The authors observed a majority preference in favor of the risky options after negative, but not positive framing. They also found, as they had predicted, that the type of framing effect varied across scenarios, with a bidirectional framing effect for the life-death scenario and unidirectional (risk averse) framing effects when public property (paintings) or personal property (money) were at stake. It is important to note that these choice preference patterns were highly similar across the age groups, which reinforced the conclusion that younger and older adults are equally susceptible to framing effects.     

History and Method of Charles V. Gerkin’s Pastoral Theology: Toward an Identity-Embodied and Community-Embedded Pastoral Theology,Part I. History

The purpose of this article is to explore the legacy of Charles V. Gerkin’s pastoral theology and to construct a method of pastoral theology. In Part I, I will trace within a larger context of pastoral theology the history of Gerkin’s pastoral theology since his early clinical praxis. In Part II, I will explore his method of developing pastoral theology and construct a renewed critical and constructive method of pastoral theology, reflecting on the implications of exploring the history and method of his pastoral theology.     

Stress, glucocorticoids and ageing of the immune system

Ageing has been associated with immunological changes (immunosenescence) that resemble those observed following chronic stress or glucocorticoid (GC) treatment. These changes include thymic involution, lower number of na?ve T cells, reduced cell-mediated immunity, and poor vaccination response to new antigens. It follows that immunosenescence could be associated with changes of peripheral GC levels. Indeed, when compared with young subjects, healthy elders are more stressed and show activation of the hypothalamus-pituitary-adrenal (HPA) axis. However, both beneficial and undesirable effects of GCs ultimately depend on the target tissue sensitivity to these steroids. Recent data indicate that peripheral lymphocytes from elders respond poorly to GC treatment in vitro. The present review summarizes recent findings which suggest that immunosenescence may be closely related to both psychological distress and stress hormones. Furthermore, chronically stressed elderly subjects may be particularly at risk of stress-related pathology because of further alterations in GC-immune signalling. Finally, the neuroendocrine hypothesis of immunosenescence is finally reconsidered in which the age-related increase in the cortisol/DHEA ratio is major determinant of immunological changes observed during ageing.     

Spatial orienting of tactile attention induced by social cues

Several studies have established that humans orient their visual attention reflexively in response to social cues such as the direction of someone else’s gaze. However, the consequences of this kind of orienting have been addressed only for the visual system. We investigated whether visual social attention cues can induce shifts in tactile attention by combining a central noninformative eye-gaze cue with tactile targets presented to participants’ fingertips. Data from speeded detection, speeded discrimination, and signal detection tasks converged on the same conclusion: Eye-gaze-based orienting facilitates the processing of tactile targets at the location of the gazed-at body location. In addition, we examined the effects of other directional cues, such as conventional arrows, and found that they can be equally effective. This is the first demonstration that social attention cues have consequences that reach beyond their own sensory modality.
