Squares in Fork Arrow Logic

In this paper we show that the class of fork squares has a complete orthodox axiomatization in fork arrow logic (FAL). This result may be seen as an orthodox counterpart of Venema's non-orthodox axiomatization for the class of squares in arrow logic. FAL is the modal logic of fork algebras (FAs) just as arrow logic is the modal logic of relation algebras (RAs). FAs extend RAs by a binary fork operator and are axiomatized by adding three equations to RAs equational axiomatization. A proper FA is an algebra of relations where the fork is induced by an injective operation coding pair formation. In contrast to RAs, FAs are representable by proper ones and their equational theory has the expressive power of full first-order logic. A square semantics (the set of arrows is U×U for some set U) for arrow logic was defined by Y. Venema. Due to the negative results about the finite axiomatizability of representable RAs, Venema provided a non-orthodox finite axiomatization for arrow logic by adding a new rule governing the applications of a difference operator. We address here the question of extending the type of relational structures to define orthodox axiomatizations for the class of squares. Given the connections between this problem and the finitization problem addressed by I. Németi, we suspect that this cannot be done by using only logical operations. The modal version of the FA equations provides an orthodox axiomatization for FAL which is complete in view of the representability of FAs. Here we review this result and carry it further to prove that this orthodox axiomatization for FAL also axiomatizes the class of fork squares.     

Self-Perceived Health among School-Aged Adolescents: a School-Based Study in Southern Brazil

This study identified which aspects regarding the dimensions of quality of life, in terms of body image, relationships with family and friends, rest and free time, school, well-being and lifestyles function as predictors of self-perceived health among school adolescents in the southern Brazil. The sample was composed of 3360 students, ninth graders in public schools in the metropolitan area of Porto Alegre/RS (Brazil). The instruments used were: a) Health Behaviour in School Children, b) Happiness Overall Life, c) Positive and Negative Affect Scale, d) General Health Questionnaire (GHQ-12), e) Brief Multidimensional Scale of Life Satisfaction in Students (BMSLSS), and f) Subscale of Cohesion of the Family Environment Scale (FES). Multiple linear regression analysis was conducted to identify the predictors of perceived health. The results revealed a model with nine predictor variables in the sense that being more satisfied with one’s own body, perceiving one’s eating habits as healthier compared to others of the same age, having a greater sense of happiness in their current life, being able to talk to one’s brothers/sisters about issues of concern, a perception of being thinner compared to other people of the same age, greater consumption of healthy food, greater presence of positive affects and being male contribute to a greater perception of health. The results show that, for this population, the health issues are beyond the concern over physical health or the presence or absence of symptoms, but also encompass behavioral, relational and psychological aspects, as well.

     

Measuring change in psychotherapeutic work with a traumatised child on the autistic spectrum

This paper describes a developmental psychotherapy undertaken with a physically disabled latency boy, with a background of significant developmental deficits and multiple psychological trauma, diagnosed by CAMHS as being on the autistic spectrum. Using an assessment framework following Anna Freud’s conceptualisation of developmental lines, pathology as a deviation from the norm was formulated. Assessments using standard psychological tests were made at the beginning, in the middle, and at the end of his therapy, in order to study the changes in his personality development. Standard assessment findings were also used to portray the fragmentation of the boy’s psyche in a concrete fashion, in order to facilitate his re-integration.     

Child Maltreatment in Vietnam: Prevalence and Cross-Cultural Comparison

This Vietnam prevalence study on child maltreatment (VPM-2014) was designed to examine the prevalence of child maltreatment in Vietnam and to compare it with the child maltreatment prevalence in the Netherlands using the same measures and procedure. Questionnaires were filled out by 1,851 students aged 12 to 17 years (47.3% were boys). Results indicated that half of the students (49.9%) reported at least 1 event of child maltreatment in the past year. Emotional abuse was most frequently reported (31.8%), followed by physical abuse, neglect, and witnessing parental conflict. Sexual abuse was the least prevalent (2.6%). Compared with the Netherlands, the prevalence rates of most types of child maltreatment were higher in Vietnam: The largest difference was with emotional abuse, followed by neglect, physical abuse, and witnessing parental conflict. Only the past-year sexual abuse prevalence in Vietnam was lower. These findings highlight the alarming problem of child maltreatment in Vietnam.     

Rooting for (and Then Abandoning) the Underdog

Although people prefer to associate with winners, there is also a strong desire to support the lovable loser or underdog. In 4 studies, we demonstrate the underdog effect and its delimiting conditions. In Studies 1 and 2, participants rooted for the underdog in judgments of athletic, business, and artistic competition. In Study 3, participants watched animated clips of struggling and nonstruggling geometric shapes. The results showed that participants showed more rooting, sympathy, and identification with struggling shapes than with nonstruggling ones. Study 4 identified conditions under which people abandon the underdog, showing that participants rooted for the underdog only when both self‐relevance and consequences were high. Theoretical implications of these findings are discussed.     

Appraisals of obsessional thoughts in normal samples

Cognitive theories of obsessive-compulsive disorder (OCD) posit that appraisals about the significance of thoughts are critical in the development and persistence of obsessions. Rachman [(1997). A cognitive theory of obsessions. Behaviour Research and Therapy, 35, 793-802.] proposes that appraisals of unwanted thoughts distinguish clinical obsessions from normal intrusive thoughts; thoughts appraised as important and personally significant are expected to be upsetting and recur. Appraisals are also expected to be related to symptoms of OCD. To explore the features of normal appraisals of obsession-like thoughts, nonclinical participants in two studies rated the personal significance of intrusive thoughts portrayed in vignettes containing prototypical themes associated with primary obsessions: aggressive, sexual, and blasphemous thoughts. Unwanted intrusive thoughts that were described as occurring more frequently were appraised as more personally significant, but participants appraised these socially unacceptable thoughts similarly whether they imagined having personally experienced them or a friend confiding about having experienced them. Appraisals in both studies were related to subclinical OC symptoms and OC beliefs.     

Effects of Self-graphing on Written Expression of Fourth Grade Students with High-Incidence Disabilities

The purpose of this study was to determine the effects of self-graphing on the writing of 3 fourth grade students with high-incidence disabilities. Measures of written expression included total number of words written and number of correct word sequences. During intervention, students self-graphed their total number of words written in response to a timed story starter. A functional relationship was found between the self-graphing intervention and the total words written and number of correct word sequences. Implications for future research and practice are discussed.     

Mothers' and fathers' speech to infants in a teaching situation

The purpose of this study was to compare mothers' and fathers' speech to their preverbal infants in a teaching situation. Thirty-two parents of 16 8-month-olds were asked to teach their infants to put a small cube into a cup. Infant Gender (2) x Birth Order (2) x Parent (2) analyses of variance were performed with repeated measures on parent. Results indicated that fathers issued more utterances and used more words per utterance than did mothers. Although there was no difference in the proportion of imperatives used by mothers and fathers, fathers' imperatives were significantly longer than mothers'; this difference was not evident for utterances that contained indirect instructions. Mothers tended to use more exact repetitions. There were differences in parental speech related to infant gender: Parents directed more utterances, particularly utterances that contained negative statements, imperatives, and exhortations, to girls than to boys. Infant Gender x Parent effects for imperatives and exhortations indicated that these differences were especially true for fathers. Overall, it appeared that fathers made greater efforts to control the situation and to direct their infants' behavior, which might have reflected mothers' and fathers' different perceptions of both their infants' ability and their own role as teachers.     

WHEN WOMEN IMBIBE

The present research examines how alcohol, or even the illusion of imbibing alcohol, affects women's perceived self-efficacy for avoiding HIV. Women ( N = 82) were randomly assigned to one of four conditions in a 2 (alcohol or no alcohol) X 2 (expect alcohol or not) balanced placebo design. After consuming alcoholic or nonalcoholic beverages, participants assessed their self-efficacy for HIV risk prevention. Both alcohol consumption and alcohol expectancy increased women's confidence that they could detect whether a potential partner was HIV positive simply by interacting with the potential partner.
