Wright Back to Dretske,or Why You Might as Well Deny Knowledge Closure

Fred Dretske notoriously claimed that knowledge closure sometimes fails. Crispin Wright agrees that warrant does not transmit in the relevant cases, but only because the agent must already be warranted in believing the conclusion in order to acquire her warrant for the premise. So the agent ends up being warranted in believing, and so knowing, the conclusion in those cases too: closure is preserved. Wright's argument requires that the conclusion's having to be warranted beforehand explains transmission failure. I argue that it doesn't, and that the correct explanation does not imply that the agent will end up warranted in believing the conclusion when transmission fails. Those who agree that transmission does fail in those cases, therefore, might as well follow Dretske in denying knowledge closure too.     

Care Ethics and Confucianism: Caring through Li

The role of li, or ritual, in Confucianism is a perceived impediment to interpreting Confucianism to share a similar ethical framework with care ethics because care ethics is a form of moral particularism. I argue that this perception is false. The form of moral particularism promoted by care ethicists does not entail the abandonment of social conventions such as li. On the contrary, providing good care often requires employing systems of readily recognizable norms in order to ensure that care is successfully communicated and completed through one's care‐giving practices. I argue that li performs this communicative function well and that the early Confucians recommend breaching li precisely when its efficacy in performing this function is compromised.     

Teachers' and coaches' role perceptions for supporting young people's mental health: Multiple group path analyses

Teachers and youth sports coaches are in prominent positions to support young people and their mental health. However, the way these professionals perceive their roles is likely to be a powerful influence on such behaviour. This article investigates and compares the effect of four types of role perceptions—role breadth, instrumentality, efficacy, and discretion—on teachers' and coaches' engagement in helping behaviour that supports young people's mental health through promotion, prevention, and early intervention. An online survey was completed by 117 teachers and 131 coaches. Results from three multiple group path analyses revealed role breadth, instrumentality, and efficacy significantly influenced teachers' and coaches' helping behaviour. The extent to which role perceptions predicted helping behaviour did not differ between teachers and coaches. Assisting teachers and coaches to carry out promotion, prevention, and early intervention behaviour increases young people's access to mental health support and may help to reduce the burden of mental health problems among Australian young people.     

HIV Testing Experience and Risk Behavior Among Sexually Active Black Young Adults: A CBPR-Based Study Using Respondent-Driven Sampling in Durham,North Carolina

African Americans are disproportionately affected by the HIV epidemic inclusive of men who have sex with men, heterosexual men, and women. As part of a community‐based participatory research study we assessed HIV testing experience among sexually active 18–30 year old Black men and women in Durham, NC. Of 508 participants, 173 (74 %) men and 236 (86 %; p = 0.0008) women reported ever being tested. Barriers to testing (e.g., perceived risk and stigma) were the same for men and women, but men fell behind mainly because a primary facilitator of testing—routine screening in clinical settings—was more effective at reaching women. Structural and behavioral risk factors associated with HIV infection were prevalent but did not predict HIV testing experience. Reduced access to health care services for low income Black young adults may exacerbate HIV testing barriers that already exist for men and undermine previous success rates in reaching women.     

Effects of Presession Pairing on the Challenging Behavior and Academic Responding of Children with Autism

Presession pairing is an antecedent‐based procedure in which an instructor engages with preferred items with a child for a few minutes before an instructional session. Although this procedure has been described in manualized treatment guidelines for working with children with autism, there are currently no direct investigations of whether this manipulation has a beneficial impact on target responding or the child's social interactions. Functional analyses with three children with autism showed escape or attention and escape as reinforcers for their challenging behavior. Preference assessments identified highly and moderately preferred stimuli. In the context of a multiple baseline across participants design, the participants exhibited fewer challenging behaviors when instructional sessions were preceded by presession pairing than when they were not. Academic responding showed modest increases. Subsequently, in the presence of presession pairing with a novel task, the participants emitted no challenging behavior and similar or higher levels of accurate academic responding. One participant was available for a maintenance session without presession pairing 5 months later and showed near‐zero levels of challenging behavior and comparable levels of accurate academic responding. The implications of the findings and future directions are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
