A convex approach for multicriteria decision making in hierarchical systems

In this paper hierarchical multicriteria optimization problems are addressed in a convex programming framework. It is assumed that the criteria are aggregated into a nonlinear function, which renders the problem nonseparable, in general. The projection of the problem onto the criteria space is used to obtain an equivalent separable problem, solved through a relaxation procedure implemented on basis of a multilevel structure. At the upper level of the structure, the decision making process involves the solution of a multicriteria problem formulated in the criteria space. The solution encountered at the upper level originates a lower level parametric optimization problem with separable structure that can be treated by standard coordination-decomposition techniques. The convergence of the overall procedure is ensured. The paper includes an application of the approach proposed for the control of dynamic systems with linear quadratic structure. © 1998 John Wiley & Sons, Ltd.     

Understanding Our Understanding of Strategic Scenarios: What Role Do Chunks Play?

There is a crucial debate concerning the nature of chess chunks: One current possibility states that chunks are built by encoding particular combinations of pieces-on-squares (POSs), and that chunks are formed mostly by "close" pieces (in a "Euclidean" sense). A complementary hypothesis is that chunks are encoded by abstract, semantic information. This article extends recent experiments and shows that chess players are able to perceive strong similarity between very different positions if the pieces retain the same abstract roles in both of them. This casts doubt on the idea that POS information is the key information encoded in chess chunks, and this article proposes, instead, that the key encoding involves the abstract roles that pieces (and sets of pieces) play-a theoretical standpoint in line with the research program in semantics that places analogy at the core of cognition.     

COCAINE ADDICTS AND THEIR FAMILIES: AN EMPIRICAL STUDY OF THE PROCESSES OF IDENTIFICATION

The processes of identification between adolescent cocaine addicts and their parents were studied in 402 subjects, in total 134 familial triads (father"mother"son), subdivided into two groups of 67 triads, one of these groups having as the child an adolescent of masculine sex dependent on cocaine and the other, equal in number, being a control group, duly matched for age and socio-economic status. The instrument employed was the Rorschach test (1922), limited to the application of the Lerner Defense Scale (LDS; Lerner & Lerner, 1980). The findings in the affected triads showed up as consistent statistically for the presence of intense processes of pathological identification, especially between father and son, a sign of the importance of the presence of disturbances of paternal function in the development of this addiction. The utilisation of very regressive defence mechanisms, above all of projective identification, was the predominant mode of procedure in triads with a dependent child. In comparisons between the fathers the odds ratio (OR) for projective identification was 8.66 to 1, which points to the association between cocaine addiction and the primitive mental functioning of the fathers. With empirical methodology these findings serve to corroborate the psychoanalytical conclusions based on studies of single case studies, testifying that the dysfunctions of identificatory phenomena in familial functioning are predominant in the mental organisation of cocaine addicts.     

Testing a modified cognitive interview with category clustering recall in Iran

The cognitive interview (CI) has been an effective method for interviewing eyewitnesses often leading to changes in legislation and practice in many countries. This study was the first to employ the CI in Iran and test whether category clustering recall (CCR) was superior to a free recall when incorporated within an investigative interview. A between‐subjects design assigned 66 participants to one of three interview conditions after they watched a mock robbery. The participants were interviewed 48 hr later using either a structured interview (SI), the CI, or a modified cognitive interview (MCI) that replaced free recall with CCR at the first retrieval attempt. Analysis of variance suggests CCR was more effective than free recall and the CI group recalled more information than the SI group, replicating the CI superiority effect. This has implications for law enforcement in Iran and worldwide by suggesting these techniques can be used to enhance recall.     

Cerebellum and processing of negative facial emotions: Cerebellar transcranial DC stimulation specifically enhances the emotional recognition of facial anger and sadness

Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognising facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=.0021; cathodal tDCS, p=.018), but left positive emotion and neutral facial expressions unchanged (p>.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.     

Perversion on the other side of the couch

Abstract

Taking as his starting point the fact that, according to Freudian theory, perversion is inherent to the human being, the author focuses upon an aspect of perversion that has been little discussed: perversion on the other side of the couch, and thereby questions of how, in psychoanalytic theoretical and clinical practice, perverted drive motions may be presented. Such a phenomenon takes various forms: actually being enacted with patients; using psychoanalytic theory as a normative rule; the individual choice of profession and so forth. To exemplify his point of view, the author presents four different expressions of sexuality in Freudian theory: genital sexuality, perverted sexuality, the sexuality of the Ideals and narcissistic sexuality. After differentiating these four sexual expressions, the author shows how each of them may generate perversion in both clinical and theoretical psychoanalysis.

Ceccarelli P Perversion auf der anderen Seite der Couch

Indem er als Ausgangspunkt die Tatsache nimmt, daß entsprechend der Freudianischen Theorie Perversion dem menschlichen Sein inhärent ist, fokussiert der Autor auf einen Aspekt der Perversion, der wenig diskutiert wurde: Perversion auf der anderen Seite der Couch und damit Fragen, wie in der psychoanalytischen und klinischen Praxis pervertierte Triebbewegungen dargestellt werden können. Ein solches Phänomen zeigt sich in verschiedenartigen Formen: tatsächlich mit Patienten in Szene gesetzt; im Gebrauch psychoanalytischer Theorie als einer normativen Regel; die individuelle Wahl des Berufs und so weiter. Um seinen Standpunkt zu exempifizieren, stellt der Autor vier verschiedene Ausdrücke von Sexualität in der Freudianischen Theorie dar: genitale Sexualität; perverse Sexiualität; die Sexualität der Ideale; und narzißtische Sexualität. Nach einer Differenzierung dieser vier Ausdrücke für Sexualität zeigt der Autor, wie jeder von ihnen Perversion in klinischer und theoretischer Psychoanalyse generieren kann.

Ceccarelli P. Perversión del otro lado del diván.

Tomando como punto de partida el hecho de que de acuerdo a la teoría Freudiana la perversión es inherente al ser humano, el autor se enfoca en un aspecto de la perversión que ha sido muy poco discutido: la perversión del otro lado del diván, se pregunta cómo en la práctica psicoanalítica clínica y teórica, algunos impulsos pervertidos pueden estar presentes. Un fenómeno así puede tomar diversas formas: pasos al acto con pacientes, usar la teoría psicoanalítica como regla normativa, la elección individual de profesión y así. Para ejemplificar su punto de vista, el autor presenta cuatro diferentes expresiones de la sexualidad en la teoría freudiana: la sexualidad genital, sexualidad pervertida, la sexualidad de los Ideales, y la sexualidad narcisista. Además de diferenciar estas cuatro expresiones sexuales, el autor demuestra como cada una de estas formas puede generar perversión en el psicoanálisis clínico y teórico.     

Anomalous spin diffusion in 3He films: Expected behaviour in two-dimensional Fermi liquids

It is shown that the recently observed and unexplained behaviour for spin diffusion in ³He films can be understood in terms of the Fermi-liquid theory, provided that non-perturbative effects characteristic of two dimensions are taken into account. It is conjectured that such a behaviour suggests the onset of a regime in which spin current is conserved.     

Dysfunctional body investment versus body dissatisfaction: Relations with well-being and controlled motivations for obesity treatment

In this study, we investigated the associations between body image and psychological well-being, exploring the mediating role of controlled regulation for entering obesity treatment. In addition, we analyzed whether investment body image was more strongly associated with controlled regulation (and subsequent well-being) compared to evaluative body image. These analyses were performed controlling for baseline BMI effects. Participants were 139 overweight women (age: 38.0 ± 6.7 year; BMI: 32.0 ± 4.1 kg/m²) entering treatment. Evaluative and investment body image, controlled regulation, and psychological well-being were assessed. Body image investment was positively associated with controlled regulation; evaluative body image was not. Controlled regulation was negatively associated with self-esteem and psychological functioning. Controlled regulation partially mediated the effects of body image investment on self-esteem, but did not mediate its effects on psychological functioning. Results suggest that dysfunctional body image investment might undermine well-being within overweight women, partly by increasing controlled regulation for entering obesity treatment. Discussion focuses on the importance of enhancing body image and autonomy during treatment to improve well-being and weight outcomes.     

Paraconsistent algebras

The prepositional calculiC _n , 1 n introduced by N.C.A. da Costa constitute special kinds of paraconsistent logics. A question which remained open for some time concerned whether it was possible to obtain a Lindenbaum's algebra forC _n . C. Mortensen settled the problem, proving that no equivalence relation forC _n . determines a non-trivial quotient algebra.The concept of da Costa algebra, which reflects most of the logical properties ofC _n , as well as the concept of paraconsistent closure system, are introduced in this paper.We show that every da Costa algebra is isomorphic with a paraconsistent algebra of sets, and that the closure system of all filters of a da Costa algebra is paraconsistent.     

Medicine: The first step on the road to holiness?

The connections of Medicine and Religion are thoroughly documented in the primitive societies, and it comes as no surprise to see them together. Here we describe the true story of a Portuguese physician of the late 19th century whose image today is venerated in such a way as to compare him to a saint and to bestow upon him miraculous powers of healing. We propose that modern day physicians can learn from the example of this man that the role of doctor encompasses not only scientific and technical mastery but, most of all, piety, humanity and compassion.
