Analyses of Model Fit and Robustness. A New Look at the PISA Scaling Model Underlying Ranking of Countries According to Reading Literacy

This paper addresses methodological issues that concern the scaling model used in the international comparison of student attainment in the Programme for International Student Attainment (PISA), specifically with reference to whether PISA’s ranking of countries is confounded by model misfit and differential item functioning (DIF). To determine this, we reanalyzed the publicly accessible data on reading skills from the 2006 PISA survey. We also examined whether the ranking of countries is robust in relation to the errors of the scaling model. This was done by studying invariance across subscales, and by comparing ranks based on the scaling model and ranks based on models where some of the flaws of PISA’s scaling model are taken into account. Our analyses provide strong evidence of misfit of the PISA scaling model and very strong evidence of DIF. These findings do not support the claims that the country rankings reported by PISA are robust.     

Biological attributions for postdeployment distress relate to higher likelihood of seeking mental health treatment in Iraq/Afghanistan service members/veterans

Service members/veterans (SM/Vs) underuse mental health care. Attribution theory suggests that attributions for psychological distress might inform help-seeking. Given recent mental health campaigns leveraging military values aimed at facilitating help-seeking for postdeployment distress, understanding how SM/Vs explain psychological distress may contribute to a better grasp of the low help-seeking rate in this population. The authors examined the association of biological and psychological attributions for postdeployment distress with help-seeking intentions from a mental health professional and medical doctor in 162 Iraq/Afghanistan SM/Vs. At the bivariate level, biological attributions were positively associated with help-seeking intentions from a mental health professional and medical doctor with small effect sizes. Psychological attributions were unrelated to help-seeking intentions from either provider. Path analysis revealed that biological attributions were positively correlated with help-seeking intentions from a medical doctor with a small effect size above and beyond the effects of psychological attributions and correlates. Biological attributions were also positively correlated with help-seeking intentions from a mental health professional with a small effect size but the significance value only trended toward significance (p = .06). Emphasizing the role of biology in postdeployment distress may promote help-seeking in SM/Vs, particularly help-seeking from medical professionals. Interventions that test the effectiveness of promoting biological explanations in campaigns aimed at increasing help-seeking may be a necessary next step in this area of inquiry.     

The association between change in cognitive ability and cause-specific mortality in a community sample of older adults

While there is consistent evidence that initial levels of cognitive ability predict mortality, there is mixed evidence for a relationship between changes in cognition and mortality. There have been few studies that have examined whether the level and slope of cognitive performance is predictive of subsequent mortality from all causes or from cardiovascular disease, stroke, heart disease, respiratory disease, or cancer. This study aimed to assess whether the level and slope of cognitive ability were associated with all-cause or cause-specific mortality. A cohort of 896 community-based elderly people in Australia was interviewed four times over 12 years, with vital status followed for up to 17 years. Of these, 592 participants completed two or more interviews and were included in survival models of six mortality outcomes. Cognitive change in five domains of ability was estimated using latent growth models. Poorer initial processing speed or verbal fluency was significantly associated with greater all-cause and/or cardiovascular mortality. In addition, declines in global ability were associated with greater all-cause, cardiovascular, and heart disease mortality. Vocabulary and episodic memory were not associated with mortality, and none of the cognitive tests significantly predicted respiratory or cancer mortality. Initial levels of cognitive ability tended to be better predictors of subsequent mortality than were changes in ability. The results suggest that vascular events may be largely responsible for the overall relationship between cognition and mortality.     

Neuropsychological profile following suicide attempt by hanging: two adolescent case reports

Hippocampal damage and amnesia following hypoxia and ischemia are described in the few published adult cases of suicide attempt by hanging. However, a recent review (Caine &; Watson, 2000 Caine, D. and Watson, J. D. 2000. Neuropsychological and neuropathological sequelae of cerebral anoxia: A critical review. Journal of the International Neuropsychology Society, 6: 86–99. [CROSSREF][Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) suggests a variable pattern of brain involvement and neuropsychological impairments following hypoxic-ischemic injury that may or may not involve amnesia. To help clarify the impact of hanging on the developing brain, we examined neuropsychological functioning in two adolescents who survived suicide attempt by hanging. Despite differences in Glasgow Coma Scale (GCS), coma duration, and structural imaging findings, both patients had similar IQ (VIQ > PIQ) and presented with various combinations of deficits in expressive/receptive language, visual-constructional and perceptual ability, processing speed, attention, working memory, and/or executive functioning shortly after injury. In spite of their similarities, only one of the patients presented with classic amnesia symptoms in his early recovery. This patient was evaluated 1 year postinjury, and persistent deficits in processing speed and memory encoding were noted. Several hanging-related variables, including longer estimated hanging duration, greater weight, and severe airway edema, were thought to place this patient at increased risk for cognitive deficits. Clinical MRI scans of this patient obtained 6 weeks postinjury revealed mild volume loss as well as abnormalities in bilateral superior cortex. However, CT and MRI scans obtained throughout early recovery did not reveal overt evidence of injury to specific memory-related structures. Comprehensive neuropsychological evaluation of all adolescent survivors of suicide attempt by hanging is recommended, as a variety of postacute cognitive deficits were observed in these patients despite relatively short (≤ 15 minutes) estimated hanging durations.     

Therapists' perspectives on home-based family therapy

Abstract

As a result of the passage of Public Law 96-272, home-based family services have proliferated throughout the United States, with family therapy playing a vital role. Voices of therapists providing these services have been absent from literature. Ten therapists participated in this study; each had experience providing home-based and clinic-based family therapy. A qualitative strategy was used to explore therapists' perspectives on factors regarding home-based family preservation services. Four themes emerged from semistructured interviews: the home environment, safety, context preference, and efficiency and effectiveness. Three recommendations are drawn from results and discussed.     

Exploring a new paradigm for empathy research / Explorando un nuevo paradigma para el estudio de la empatía

Abstract

The present paper proposes an alternative experimental procedure for studies on empathy. It is intended as a simple and reliable alternative to the commonly used designs, which are certainly very elegant, but costly, as they require delicate real-life experimental manipulations. We advocate that studies using simple well-formulated text stimuli can be methodologically as reliable and valid as game task approaches. To underscore our claim, we report first behavioural evidence that supports this conclusion. The clear advantage of the method we present is that it is less susceptible to bias and, more importantly, more accessible to laboratories that do not have the financial means and the spatial infrastructure to manoeuvre complex and costly experimental setups and techniques. It is an easy to use, computer-based paradigm.     

Dispersion in Cognitive Ability as a Function of Age: A Longitudinal Study of an Elderly Community Sample

This longitudinal study investigated whether age is associated with increased dispersion among major domains of cognitive ability. Three samples were examined: the full sample of 760 elderly community dwellers aged 70 years and older who were tested in 1990; a subset of the original sample who died between testing occasions; and the sample of 426 who survived with full data sets in 1994 (followed up for a mean 3.5 years). Dispersion, as measured by the within-individual standard deviation of ability scores and by the within-individual deviations from crystallized intelligence for speed, memory and spatial functioning, was significantly correlated with age in all three samples at Wave 1 and at Wave 2 (for the longitudinal sample). The rate at which dispersion increased was not significantly correlated with age. In a more detailed analysis of the 426 survivors, dispersion as a function of age was similar for demented persons within this sample, those without dementia, those with poor and excellent educational levels, and those with a physical disability. Activities of daily living was a predictor of larger-than-average changes in dispersion – but not age, education, or activity. Greater dispersion was associated with faster deterioration in memory and speed performance. Contrary to some recent reports, there was evidence for greater within-individual variability among cognitive domains in older individuals.     

Escape from Twin Earth: Putnam's 'Logic' of Natural Kind Terms

Many still seem confident that the kind of semantic theory Putnam once proposed for natural kind terms is right. This paper seeks to show that this confidence is misplaced because the general idea underlying the theory is incoherent. Consequently, the theory must be rejected prior to any consideration of its epistemological, ontological or metaphysical acceptability. Part I sets the stage by showing that falsehoods, indeed absurdities, follow from the theory when one deliberately suspends certain devices Putnam built into it , presumably in order to block such entailments. Part II then raises the decisive issue of at what cost these devices do the job they need to do. It argues that - apart from possessing no other motivation than their capacity to block the consequences derived in Part I - they only fulfil this blocking function if they render the theory unable to deal with fiction and related 'make-believe' activities. Part III indicates the affinity Putnam's account has with the classically 'denotative' view of meaning, and thus how its weaknesses may be seen as a variant of the classical weakness of 'denotative' approaches. It concludes that the theory is a conceptual muddle.     

The Problem of das Man—A Simmelian Solution

Current interpretations of Heidegger's notion of das Man are caught in a dilemma: either they cannot accommodate the ontological status Heidegger accords it or they cannot explain his negative evaluation of it, in which it is treated as ontic. This paper uses Simmel's agonistic account of human sociality to integrate the ontological and the ontic, indeed perjorative aspects of Heidegger's account. Section I introduces the general problem, breaks the exclusive link of Heidegger's account to Kierkegaard and delineates the general form of a solution. Section II then sketches Simmel's conception of sociology and sociality. Section III determines what Heidegger is trying to do in Chapter Four of Division I in Being and Time in order to formulate a strictly ontological account of das Man. Section IV uses Simmel's account of sociality to build into this ontological account an inherent tendency to display the negative features Heidegger ascribes to das Man. In conclusion, section V points to how the proposed account of das Man intimates the character of fundamental ontology as nascently a form of critical theory. It also explains the extent to which Heidegger's perjorative characterisations of das Man and the Man-selbst are legitimate.
