A Theory of Truthmaker Content I: Conjunction,Disjunction and Negation

I develop a basic theory of content within the framework of truthmaker semantics and, in the second part, consider some of the applications to subject matter, common content, logical subtraction and ground.     

Problem-solving training via videoconferencing for family caregivers of persons with spinal cord injuries: a randomized controlled trial

Objective

To examine the effectiveness of an individualized problem-solving intervention delivered in videoconferencing sessions with family caregivers of persons living with a spinal cord injury (SCI) and possible contagion effects on care recipients.

Design

Family caregivers were randomly assigned to an education-only control group or an intervention group in which participants received problem-solving training (PST) in monthly videoconference session for a year.

Participants

Sixty-one caregivers (54 women, 7 men) and their care recipients (40 men, 21 women) consented to participate.

Main outcome measures

The Social Problem-Solving Inventory-Revised was administered to caregivers. Caregivers and care recipients completed the Inventory to Diagnose Depression, the SF-36 and the Satisfaction with Life scale at pre-treatment, 6 months and 12 months.

Results

Twenty-eight caregivers discontinued the study and their follow-up data were unavailable at the final assessment. Older caregivers were more likely than younger caregivers to remain in the study. Intent-to-treat analyses projected a significant decrease in depression among caregivers receiving PST; efficacy analyses indicated this effect was pronounced at the 6th month assessment. ITT analyses and efficacy analyses revealed that care recipients of caregivers receiving PST reported gains in social functioning over time.

Conclusions

Community-based, telehealth interventions may benefit family caregivers and their care recipients, but the mechanisms of these effects are unclear. Attrition and sample issues should be considered in future studies with these populations.     

Nonspatial attributes of stimuli can influence spatial limitations of attentional control

A wide variety of psychophysical and neurophysiological research suggests that when stimuli are very close together, they cannot be attended separately. As a consequence, they cannot be represented as individual items with specific feature information associated with them. Here we report evidence that the spatial control of attention can be modulated by nonspatial features of the stimuli (such as color and luminance). Observers shifted attention from item to item within highly dense arrays of stimuli. Performance was extremely poor when all of the items in the array were an identical gray. In contrast, performance improved when items differed in color. This finding indicates that nonspatial features, such as color, can facilitate spatial selection and suggests moreover that features can be reliably associated with particular items even when the items are densely clustered.     

The RealIty of Tense

I argue for a version of tense-logical realism that privileges tensed facts without privileging any particular temporal standpoint from which they obtain.     

Pre-employment integrity testing across multiple industries

Despite the robust meta-analytic data available, very little comparative research exists on validities of integrity measures within specific industries. Among a sample of 2456 Israeli job applicants, integrity scores were found to be significantly correlated with self-reported counterproductive work behaviors across eight different industries, with no evidence of adverse impact by gender, age, or national origin. These results are believed to be of practical importance to the diverse organizations administering integrity tests.     

Identity criteria and ground

I propose formulating identity criteria as generic statements of ground, thereby avoiding objections that have been made to the more usual formulations.     

On Defining “Reliance” and “Trust”: Purposes,Conditions of Adequacy,and New Definitions

Philosophia - Trust is often perceived as having great value. For example, there is a strong belief that trust will bring different sorts of public goods and help us preserve common resources. A...
