Cofinal Stable Logics

We generalize the \({(\wedge, \vee)}\)-canonical formulas to \({(\wedge, \vee)}\)-canonical rules, and prove that each intuitionistic multi-conclusion consequence relation is axiomatizable by \({(\wedge, \vee)}\)-canonical rules. This yields a convenient characterization of stable superintuitionistic logics. The \({(\wedge, \vee)}\)-canonical formulas are analogues of the \({(\wedge,\to)}\)-canonical formulas, which are the algebraic counterpart of Zakharyaschev’s canonical formulas for superintuitionistic logics (si-logics for short). Consequently, stable si-logics are analogues of subframe si-logics. We introduce cofinal stable intuitionistic multi-conclusion consequence relations and cofinal stable si-logics, thus answering the question of what the analogues of cofinal subframe logics should be. This is done by utilizing the \({(\wedge,\vee,\neg)}\)-reduct of Heyting algebras. We prove that every cofinal stable si-logic has the finite model property, and that there are continuum many cofinal stable si-logics that are not stable. We conclude with several examples showing the similarities and differences between the classes of stable, cofinal stable, subframe, and cofinal subframe si-logics.     

Vital Wheels: Disability,Relationality, and the Queer Animacy of Vibrant Things

This article probes the philosophical and political significance of the relationships between wheelchair activists and their wheelchairs. Analyzing disability memoirs and the work of a professional wheelchair dancer, I argue that wheelers frequently experience complex relationality and queer kinships with their wheels. By bringing the artistry of disabled writers and dancers into conversation with the notions of human–material relations in the work of Donna Haraway, Jane Bennett, Stacy Alaimo, and Mel Chen, I show how alternative animacies shape wheelers’ conceptions of interdependence and movement. The sensuous pleasure they take in their wheels queers conventional conceptions of how humans should relate to things. New materialist philosophy has increasingly drawn attention to the porous boundaries between the human and material world. But where posthumanist philosophers have largely aimed to dethrone the sovereignty of the human, disability activists use alternative animacies to raise up a devalued and discounted portion of humanity: to emphasize the agency and capacity of those whose lives are often cast as pitiable and powerless, to express a queer feminist disability culture and politics, and to claim the transgressive vitality and vibrant artistry of life with disability.     

Me,Myself, and Mobility: The Relevance of Region for Young Adults' Identity Development

As residential mobility is a common life event that particularly affects young adults, regional identity may be relevant for young adults. We therefore extended the three‐dimensional identity model to the regional domain. The development of regional identity was studied using a prospective design over six months with a sample of 1,795 post‐secondary graduates (71% female, mean age of 24.54 years), containing both movers and non‐movers. Latent profile analyses and latent profile transition analyses revealed three main findings: First, solutions with four regional identity statuses—moratorium, searching moratorium, closure, and achievement—were found to be most interpretable. Second, the emergent statuses differed substantially in terms of Big Five personality traits and life satisfaction, as well as with moving experience. Third, the stability of identity status membership across a period of six months was highest for the non‐movers group. Comparatively less stability across time was found for the movers, underscoring the relevance of transitions for identity development. Taken together, these findings show that even in a mobile world, region matters in identity development. Copyright © 2016 European Association of Personality Psychology     

Self‐Efficacy Among Adults in Substance Abuse Treatment: The Role of Religious Coping

In substance abuse treatment, general self‐efficacy and religiousness are factors that may support positive outcomes. The authors surveyed clients receiving substance abuse treatment (N = 121) and found that religious coping predicted general self‐efficacy scores. Clinical implications are discussed.     

Mother–Daughter Relationship Quality and Body Image in Preadolescent Girls

Research suggests that mothers may play a role in girls’ body image development. The “interactive” hypothesis specifies that qualities of the mother–daughter relationship, as opposed to maternal modeling alone, predict daughter’s body image. We sought to understand how maternal relationship quality, from the perception of both daughters and mothers, was associated with preadolescent girls’ body image. The relationship between mother–daughter relationship quality and daughters’ body image was examined in 152 girls (ages 8–12) and their mothers. Mothers and daughters primarily identified as non-Hispanic white or Hispanic. Hierarchical linear regression analyses indicated that daughters’ perception of mother–daughter relationship quality was associated with daughters’ body esteem and body dissatisfaction, adding a small, but significant, amount of variance above the larger effect of child z-BMI and age. In contrast, maternal perception of mother–daughter relationship quality was not associated with any child body image measures. Young girls who perceived their relationships with their mothers more positively had healthier body images. Although effect sizes were relatively small and the cross-sectional design precludes conclusions regarding causality, these results support the “interactive” model of body image development whereby the characteristics of the mother–daughter relationship (as perceived by the daughter) are related to body image. Our findings support the notion that daughters’ perceptions of strong mother–daughter relationships are associated with healthy child body image, and fall in line with family-based prevention efforts that attempt to enhance parent–child relationships.     

A Positive Psychology Intervention for Patients with an Acute Coronary Syndrome: Treatment Development and Proof-of-Concept Trial

Positive psychological constructs are associated with superior outcomes in cardiac patients, but there has been minimal study of positive psychology (PP) interventions in this population. Our objective was to describe the intervention development and pilot testing of an 8-week phone-based PP intervention for patients following an acute coronary syndrome (ACS). Initial intervention development and single-arm proof-of-concept trial, plus comparison of the PP intervention to a subsequently-recruited treatment as usual (TAU) cohort. PP development utilized existing literature, expert input, and qualitative interview data in ACS patients. In the proof-of-concept trial, the primary outcomes were feasibility and acceptability, measured by rates of exercise completion and participant ratings of exercise ease/utility. Secondary outcomes were pre-post changes in psychological outcomes and TAU comparisons, measured using effect sizes (Cohen’s d). The PP intervention and treatment manual were successfully created. In the proof-of-concept trial, 17/23 PP participants (74 %) completed at least 5 of 8 exercises. Participants rated the ease (M = 7.4/10; SD = 2.1) and utility (M = 8.1/10, SD = 1.6) of PP exercises highly. There were moderate pre-post improvements (ds = .46–.69) in positive affect, anxiety, and depression, but minimal effects on dispositional optimism (d = .08). Compared to TAU participants (n = 22), PP participants demonstrated greater improvements in positive affect, anxiety, and depression (ds = . 47–.71), but not optimism. A PP intervention was feasible, well-accepted, and associated with improvements in most psychological measures among cardiac patients. These results provide support for a larger trial focusing on behavioral outcomes.     

The roles of family history of dyslexia,language, speech production and phonological processing in predicting literacy progress

It is well established that speech, language and phonological skills are closely associated with literacy, and that children with a family risk of dyslexia (FRD) tend to show deficits in each of these areas in the preschool years. This paper examines what the relationships are between FRD and these skills, and whether deficits in speech, language and phonological processing fully account for the increased risk of dyslexia in children with FRD. One hundred and fifty‐three 4–6‐year‐old children, 44 of whom had FRD, completed a battery of speech, language, phonology and literacy tasks. Word reading and spelling were retested 6 months later, and text reading accuracy and reading comprehension were tested 3 years later. The children with FRD were at increased risk of developing difficulties in reading accuracy, but not reading comprehension. Four groups were compared: good and poor readers with and without FRD. In most cases good readers outperformed poor readers regardless of family history, but there was an effect of family history on naming and nonword repetition regardless of literacy outcome, suggesting a role for speech production skills as an endophenotype of dyslexia. Phonological processing predicted spelling, while language predicted text reading accuracy and comprehension. FRD was a significant additional predictor of reading and spelling after controlling for speech production, language and phonological processing, suggesting that children with FRD show additional difficulties in literacy that cannot be fully explained in terms of their language and phonological skills.
