Frequency of judgment as a context-like determinant of predictive judgments

Several studies have shown that predictive and causal judgments vary depending on whether the question used to assess the relationship between events is presented after each piece of information or only after all the available information has been observed. This effect could be understood by assuming that in the two cases people perceive that the test question requires that different sets of evidence be taken into account. This hypothesis is tested in the present experiments through contextual manipulations that take place at the time of training and at the time of test. Our results show that people use this contextual information to infer which set of events should be considered when making their subjective assessments. The results are at odds with current theoretical approaches, but it is possible to develop mechanisms that would allow these models to account for the observed evidence.     

Treatment of children with ADHD: psychopedagogical program at school versus psychostimulant medication

This study examined the impact of medication management compared to a psycho-educational program on parent and teacher ratings of children with combined type ADHD. The study lasted 14 weeks and included 50 children. 17 children took medication, 17 received psycho-educational intervention, and 16 children were assigned to the control group. The measures used were the IOWA Conners Scale, the School Problem Inventory, the Abbreviated Conners, and the DSM-IV Inattention-Disorganization and Hyperactivity-Impulsivity rating scales. Regarding teacher ratings, improvements were observed on: a) inattention and school problems in the medication group versus the control group; and b) hyperactivity symptoms in the psycho-pedagogical group versus the control and medication groups. Regarding to parent ratings, improvements were observed on: a)inattention in the psycho-pedagogical group versus the control and medication groups; and b) hyperactivity symptoms in the psycho-pedagogical group versus the control and the medication groups.     

Measuring stress resilience and coping in vulnerable youth: the Social Competence Interview

A brief interview to measure stress coping capabilities was developed and tested in 4 samples of African American and White adolescents in low-income neighborhoods of 2 large U.S. cities. The Social Competence Interview (SCI) is a 10-min social stressor that assesses physiological and social-emotional responses to a recurring real-life problem. A new behavioral coding system using audiotapes permits reliable and valid assessment of components of social competence, including Interpersonal Skills (expressiveness, empathy), Goal-Oriented Strivings in coping (self defense, social acceptance, competitiveness, stimulation-pleasure, approval, self improvement), and Social Impact (high vs. low affiliation/control). High SCI expressiveness and self-defensive striving create a critical-aggressive social impact, which is correlated with increased hostility and anger.     

Linking organizational resources and work engagement to employee performance and customer loyalty: the mediation of service climate

This study examined the mediating role of service climate in the prediction of employee performance and customer loyalty. Contact employees (N=342) from 114 service units (58 hotel front desks and 56 restaurants) provided information about organizational resources, engagement, and service climate. Furthermore, customers (N=1,140) from these units provided information on employee performance and customer loyalty. Structural equation modeling analyses were consistent with a full mediation model in which organizational resources and work engagement predict service climate, which in turn predicts employee performance and then customer loyalty. Further analyses revealed a potential reciprocal effect between service climate and customer loyalty. Implications of the study are discussed, together with limitations and suggestions for future research.     

Feeding upon awakening in breastfeeding and bottlefeeding mothers does not affect the awakening cortisol response

An acute breastfeeding stimulus is generally followed by a transient decrease in cortisol levels in mothers. It is currently not clear whether breastfeeding upon waking up would affect the awakening cortisol response (ACR), a significant increase in salivary cortisol levels occurring within 30-45 min after awakening. In the present study, we measured the amplitude and stability of the ACR in response to infant feeding in women who were exclusively bottle-feeding (n = 16), or breastfeeding (n = 13) or feeding their child solid food (n = 12). The results show that the type of infant feeding did not affect the amplitude and stability of the ACR. Given that the ACR has been reported to reflect physical and psychological well-being, our finding that infant feeding upon waking up might not be a confounding factor in ACR studies on the postpartum population represents valuable methodological information.     

Role of Stressful Life Events in Homelessness: An Intragroup Analysis

The present paper describes the results of an analysis of individual differences—using multidimensional strategies—in stressful life event data collected from a representative sample of homeless people (N = 289) in Madrid, Spain, which revealed the existence of three subgroups within the sample. Each subgroup can be defined by the following differentiating characteristics: The first cluster (n = 124) was characterized by economic problems; the second (n = 80) by health problems, alcohol abuse, and death of one or both parents; and the third cluster (n = 50) by an accumulation of stressful life in childhood events and alcohol abuse. In order to define the subgroups, the article also examines the differences found in other variables such as total duration of homelessness, mental and physical health status, and social support availability, among others. The existence of such subgroups within the homeless population emphasizes the importance of designing different interventions for each of these groups, adapted to their diverse needs.     

Identity Politics and Dialectical Reason: Beyond an Epistemology of Provenance

Identity politics is important within feminism. However, it often presupposes an overly subjectivist theory of knowledge that I term an epistemology of provenance. I explore some works of feminist standpoint theory that begin to address the difficulties of such an epistemology. I then bring Sartre's account of knowledge in the Critique of Dialectical Reason to bear on these difficulties, arguing that his work offers tools for addressing them more adequately.     

R&D system in the petrochemical industry in Brazil: Institutional challenge under privatization

Brazil has achieved a tremendous, short-term growth in its petrochemical sector. In 1989 it placed eleventh in the world ranking of petrochemical producers. The main factor responsible for this success was the establishment of three integrated petrochemical complexes in which the government stimulated joint-ventures between a state enterprise, national private and foreign corporations: the so-called “tripartite model.” In this model, foreign partners should provide the necessary technology, state enterprise financial capital and access to raw materials, and the national private bouregoisie legitimacy to the state, as well as, access to the Brazilian market. The tripartite model promoted the creation of several small, single-product petrochemical firms without entrepreneurial scale to carry out efficient R&;D activities. The result is that the Brazilian petrochemical sector is at risk of becoming technologically static and, consequently, uncompetitive; hampering further national capital accumulation. The R&;D system, originally designed to complement the inventive activities of firms, was based on government research centers. In 1988, a new institutional design was proposed, based on a research center managed by the state holding company PETROQUISA. The conception changed from state intervention toward shared responsability by stockholders. This institutional change opens two basic questions: Given that the locus of innovation in this industry has been historically located in the firm, can any other institutional arrangement substitute it?; and, will it be possible, given the government privatization program, to develop a R&;D system on the assumption that stockholders are willing to share the cost of R&;D activities? This article addresses these two questions.     

Debating drunk driving: The construction of causal explanations in television discussion programmes

The mass media are an important source of social understandings and representations. The growing genre of audience discussion programmes functions as a public forum for airing opinions on issues of social concern. The genre is structured so as to involve viewers, to validate ordinary experiences and to express opinion. Four programmes on drunk driving were analysed for the causal explanations they offer viewers. The causes, effects and causal interconnections used within each programme were analysed, and networks of the overall representations of drunk driving were constructed. These showed a broad consensus of causes and effects across programmes, but different explanations in terms of locus, stability and controllability. Programmes typically offered lists of important factors, rather than structured arguments, despite the debating framework. There was an emphasis on external, stable, controllable causes in the programmes.
