Counselors of unruly, runaway, truant, or delinquent children and their families run the risk of emotional overexposure– “burnout” as a result of intense client needs and problems. Survival on the job requires taking steps to avoid internalizing caseload pressures. These steps include: helping-not replacing-parents, keeping meetings brief, responding to emergencies selectively, taking simple steps first, using humor, taking care of oneself, expecting complications, avoiding panic, and knowing when to withdraw.  相似文献

Reviews, compares and evaluates a self-justijication and a decision theoretical conceptualization of equity. It is argued that the latter approach reveals an important and often neglected distinction between equity as a goal of social interaction and equity as an interpersonal strategy employed in rhe pursuit of other valued goals. Associated problems of definition and measurement are discussed. After a review of relevant research it is concluded that equity serves predominantly as an accommodative interpersonal strategy, and that future research should focus on analyzing the various functional bases of equity, their relationships, and their eflects on behaviour.  相似文献

We use a deontic logic of collective agency to study reducibility questions about collective agency and collective obligations. The logic that is at the basis of our study is a multi-modal logic in the tradition of stit (‘sees to it that’) logics of agency. Our full formal language has constants for collective and individual deontic admissibility, modalities for collective and individual agency, and modalities for collective and individual obligations. We classify its twenty-seven sublanguages in terms of their expressive power. This classification enables us to investigate reducibility relations between collective deontic admissibility, collective agency, and collective obligations, on the one hand, and individual deontic admissibility, individual agency, and individual obligations, on the other.

Assessments for spatial working memory (SWM) in pet dogs that can detect age-related cognitive deficits in a single session may aid in diagnosing canine dementia and may facilitate translational research on Alzheimer’s disease in humans. Adaptive testing procedures are widely used in single-session assessments for humans with diverse cognitive abilities. In this study, we designed and deployed two up-down staircase assessments for SWM in which 26 pet dogs were required to recall the location of a treat hidden behind one of two identical boxes following delays of variable length. In the first experiment, performance tended to decline with age but few dogs completed the test (n?=?10). However, all of the dogs that participated in the second experiment (n?=?24) completed the assessment and provided reliable evidence of learning and retaining the task. Delay length and age significantly predicted performance supporting the validity of this assessment. The relationships between age and performance were described by inverted U-shaped functions as both old and young dogs displayed deficits in weighted cumulative-scores and trial-by-trial performance. Thus, SWM in pet dogs may develop until midlife and decline thereafter. Exploratory analyses of non-mnemonic fixation strategies, sustained engagement, inhibitory control, and potential improvements for future SWM assessments which adopt this paradigm are also discussed.
