Selected behavioral features of patients with borderline personality traits

Selected behavioral features felt historically and empirically to be significant in the borderline personality disorder were evaluated in 4,800 psychiatric inpatients. Variables measured included number of hospitalizations and type of discharge, suicidal behavior, physical violence, and outcome after discharge. A statistical analysis was performed to determine the relationship between depth and severity of borderline traits and the aforementioned behavioral features. Results indicated that irregular discharges, frequent suicide attempts, first suicide attempt prior to age 40, violence within and outside the hospital, and gradual deterioration in social and occupational functioning were found significantly more often in patients with high levels of borderline personality traits.     

Permissible Use and Interdependence: Against Principled Veganism

Are animals not ours to use? According to proponents of veganism such as Gary Francione, any and all use of animals by humans is exploitative and wrong. It is wrong because animals have intrinsic worth and humans' use of animals fails to respect that worth. Contra Francione, I argue that that there are conditions under which it may be morally appropriate to collect, consume, sell, or otherwise use animal products. Francione is mistaken in his belief that assigning intrinsic worth to a being is impossible if said being is also conceived as a resource. Using and (non‐instrumental) valuing are not mutually exclusive; if they were, many if not most human relationships would be deemed morally unacceptable. Through a series of thought experiments involving intra‐human relationships, I suggest that moral condemnation of relationships within which a less dependent party regularly takes from a more dependent party is indefensible. In fact, relationships of use between asymmetrically dependent parties are essential to the functioning of cooperative society, and are therefore desirable. My aims with this article are to convince readers of the need to reject principled veganism, and to garner support for new philosophical accounts of morally appropriate human‐nonhuman animal relationships.     

Effects of a multicomponent intervention on motivation and sun protection behaviors among midwestern beachgoers.

Skin cancer is the most prevalent of all cancers in the United States. Although avoiding sun exposure and using sun protection reduces skin cancer risk, rates of such behaviors are moderate at best. The present study examined the impact of a multicomponent intervention that aimed to increase the saliency of skin cancer risk while promoting the use of sun protection. Midwestern beachgoers (n = 100) participated in an intervention or questionnaire-only control group. Sun protection, stage of change, and sun exposure were measured at baseline and 2-month follow-up. The intervention group significantly improved in sun protection use and stage of change, but not sun exposure, compared with the control group. Personalizing the risks of unprotected sun exposure combined with providing education about sun protection facilitated healthy changes in behavior and motivation.     

Effects of chlordiazepoxide on pausing during rich-to-lean transitions

Extended pausing during discriminable transitions from rich-to-lean conditions can be viewed as escape (i.e., rich-to-lean transitions function aversively). Thus, an anxiolytic drug would be predicted to mitigate the aversiveness and decrease pausing. In the current experiment, pigeons' key pecking was maintained by a multiple fixed-ratio fixed-ratio schedule of rich (i.e., larger) or lean (i.e., smaller) reinforcers. Intermediate doses (3.0-10.0 mg/kg) of chlordiazepoxide differentially decreased median pauses during rich-to-lean transitions. Relatively small decreases in pauses occurred during lean-to-lean and rich-to-rich transitions. Effects of chlordiazepoxide on pausing occurred without appreciable effects on run rates. These findings suggest that signaled rich-to-lean transitions function aversively.
