Detection of change in shape: an advantage for concavities

Shape representation was studied using a change detection task. Observers viewed two individual shapes in succession, either identical or one a slightly altered version of the other, and reported whether they detected a change. We found a dramatic advantage for concave compared to convex changes of equal magnitude. Observers were more accurate when a concavity along the contour was introduced, or removed, compared to a convexity. This result sheds light on the underlying representation of visual shape, and in particular the central role played by part-boundaries. Moreover, this finding shows how change detection methodology can serve as a useful tool in studying the specific form of visual representations.     

Counsellor role perceptions and preferences of Zimbabwe teachers of a Shona cultural background

Thurstone's Case V paired comparisons procedure was used to investigate the perceived role status and preferences of counsellor for a sample of Zimbabwe teachers of a Shona cultural backgroud (n = 312) in relation to type of presenting problem (personal; educational; employment) and as the teachers varied by gender, age, level of formal educationa and marital status. Counsellor expertise contrasted those of modern status (psychologist; church pastor; work supervisor) and traditional status (family members; traditional healer; friend). The teachers seemed to have an undifferentiated perception of counselling needs as measured by preferences for helper. Age jand level of formal education were significantly related to counsellor prefernces, with the older and less schooled teachers tending to endorse counsellors of a traditional status. The results are considered with respect to the provision as well as public image of counselling services in an African culture.     

The curfew bill as it relates to the juvenile and his family

Curfew laws have been instituted in cities across the United States in an attempt to control the rise in juvenile crime. This article discusses the advantages and disadvantages of a curfew law for Baltimore City based on interviews with city officals and concludes that the law in its present form will not bring about any significant change in the rate of delinquency. Alternative are suggested that might better get to the source of the problem. These include more youth and family counseling services, rehabilitative facilities, work study programs and shelter areas.     

Triadic transferences of pathological family images

Traditionally, self-object and psychosexual transferences have been thought of as dyadic processes. This paper emphasizes the importance of seeing the triadic transferences that are contained within the more visible dyadic transferences. Triadic transferences are the partial recreation of replicas of pathological family images that were constructed from experiences with father-motherchild triads during childhood. Detecting them lessens the likelihood of therapeutic impasses occurring which resemble family of origin dyadic alliances. Childhood development and developmental arrest are discussed from a triadic perspective. In a healthy psychological family a triadic heterosexual family image is constructed which contains a triadic self and a resolved Oedipus.Revision of a paper presented at the 12th International Congress of the International Association for Child and Adolescent Psychiatry and Allied Professions, Kyoto, Japan, July 20, 1990. A preliminary version, entitled Triadic Transferences, was presented at the 12th Annual Meeting of the American Family Therapy Association, Philadelphia, PA, June 21, 1990.The masculine gender form is used for convenience, but with the recognition that statements apply to both genders.     

Paraconsistent logic and model theory

The object of this paper is to show how one is able to construct a paraconsistent theory of models that reflects much of the classical one. In other words the aim is to demonstrate that there is a very smooth and natural transition from the model theory of classical logic to that of certain categories of paraconsistent logic. To this end we take an extension of da Costa'sC ₁ ⁼ (obtained by adding the axiom A A) and prove for it results which correspond to many major classical model theories, taken from Shoenfield [5]. In particular we prove counterparts of the theorems of o-Tarski and Chang-o-Suszko, Craig-Robinson and the Beth definability theorem.     

Effects of the medical resonance therapy music® on haemodynamic parameter in children with autonomic nervous system disturbances

The present investigation is dedicated to the effects of the Medical Resonance Therapy Music^® (MRT-Music) on basic haemodynamic parameter in children with transient arterial hypertension due to disturbances of the autonomic nervous system with different degrees of initial sympatheticotonia. After the nuclear accident at Chernobyl many children developed blood pressure too high for their age norm. Having already observed a decrease in high blood pressure in pregnant women during Medical Resonance Therapy Music (Gerasimovich, Einysh, 1999; Gerasimovich, Sidorenko, 1995; Sidorenko, Tetiorkina, Korotkov, 1997) we studied the effects of the Medical Resonance Therapy Music^® (MRT-Music) on such children—with very positive results: the treatment with the music preparations demonstrated a clear sympatholythic effect and led the disturbed haemodynamic state back to its healthy age norm.     

Effects of the medical resonance therapy music in the complex treatment of epileptic patients

The purpose of the study was to evaluate the effectiveness of Medical Resonance Therapy Music (MRT-Music) as a psycho-physiological method for the treatment of epilepsy in severe epileptic patients, whose attacks persevered despite comprehensive drug treatments. Under investigation were frequency and severity of epileptic attacks, the subjective state, the dynamics of the inter-paroxysmal symptoms and the individual parameters of the functional asymmetry of the brain (IPFA). Frequency and severity of the paroxysms changed positively in 80 percent of the cases: frequency of attacks were reduced by 75 percent and many attacks manifested in the form of abortive variants. The paroxysmal component, the degree of amnesia and the polymorphism of the attacks were reduced. Such positive changes were 4 times less frequent in the control group. Changes in subjective state were 90 percent positive: the patients felt more healthy, were calmer, had a better mood and fewer ups and downs in mood, released tension, and reduced unrest, wrath, and irritation. The evaluation of the Minnesota Multiphasic Personality Inventory (MMPI) showed clear improvements in the inter-paroxysmal clinical picture, particularly in those paramaters that characterise the general degree of sickness, psychasthenic and paranoid traits, hypochondria, aggression and depressive states. Similar positive changes in the control group were observed two times less frequently. The changes of the IPFA-values were positive in 73.3 percent of the patients (27.8 percent in controls), had differently directed shiftings, were dependent on the initial level, and were determined by the location of the epileptic focus. *** DIRECT SUPPORT *** A31BB039 00004     

A consciousness-based quantum objective collapse model

Ever since the early days of quantum mechanics it has been suggested that consciousness could be linked to the collapse of the wave function. However, no detailed account of such an interplay is usually provided. In this paper we present an objective collapse model (a variation of the Continuous Spontaneous Location model) where the collapse operator depends on integrated information, which has been argued to measure consciousness. By doing so, we construct an empirically adequate scheme in which superpositions of conscious states are dynamically suppressed. Unlike other proposals in which “consciousness causes the collapse of the wave function,” our model is fully consistent with a materialistic view of the world and does not require the postulation of entities suspicious of laying outside of the quantum realm.

     

Classroom racial proportion: influence on self-concept and social competence in Zimbabwean adolescents

The authors measured self-concept and social competence relationships in 372 Zimbabwean adolescents (41% Black, 59% White) who attended classrooms in which they were either a racial minority or a racial majority (M age = 12.95 years, SD = 1.47). The authors used self-, peer-, and teacher-rating scale sociometric measures of social competence and a multidimensional measure of self-concept. The regression analysis predicted self-concept from social competence measures. Teacher-rated social competence predicted physical appearance self-concept in the Black adolescents and reading self-concept in White adolescents in White-majority classrooms. Self-rated social competence and peer-rated social competence predicted school self-concept in Black adolescents attending Black-majority classrooms. The authors concluded that classroom racial proportions influence aspects of social perception of Black and White adolescents.
