A laboratory study on the predatory mite,Typhlodromus pyri (Acarina: Phytoseiidae). II The effect of temperature and prey consumption on the numerical reponse of adult females

Summary The numerical response of adult femaleT. pyri feeding on different levels of ERM larvae, and at a range of temperatures was examined. The duration of the pre-oviposition period decreased as larval consumption increased, and the rate of oviposition was linearly related to the rate of consumption of larvae. Mathematical models were used to describe these relationships in terms of temperature and consumption of ERM larvae. The results were discussed in relation to the nature of theT. pyri/ERM interaction in New Zealand apple orchards.     

The child and adolescent social perception measure

Tests currently available for measuring children's sensitivity to nonverbal aspects of communication have been criticized on methodological and conceptual grounds. The Child and Adolescent Social Perception Measure (CASP) was developed to meet the need for a clinically useful measure which examines social perception within a semi-naturalistic context. The CASP consists of 10 videotaped scenes, each of which lasts 19–40 seconds. The verbal content was removed through electronic filtering so that the ability to receive and interpret nonverbal social cues could be measured without bias from verbal cues. Children are shown the scenes and then questioned about the emotions portrayed. Based on standardization with 212 children and adolescents ages 6 to 15 years old, reliability (interrater, test-retest, internal consistency) and initial validity information are reported.Portions of this paper have been presented at the Congress of the World Federation of Occupational Therapists, London, England, 1994, and at the joint conference of the Canadian and American Occupational Therapists, Boston, 1994.We acknowledge funding from the Glenrose Rehabilitation Hospital Research Grants Program. We thank each of the actors and actresses who generously volunteered their time to produce the videotape; the students and teachers in the schools who participated in the collection of the normative data; and the research assistants who worked many hard hours to make this all possible (Janet L.

Familiarity effects in nonverbal understanding: Recognizing our own facial expressions and our friends'

In this study we explored how individuals' private expressions are interpreted by the self, same-sex friends, and strangers. Videotapes were made of participants as they watched pleasant, unpleasant, and unusual slides. Approximately a year later, the tapes were shown to the participant, a same-sex friend, another participant, and the other participant's friend. Judges were able to read the facial expressions at levels of accuracy that were significantly greater than chance. They were no better at reading familiar targets (themselves or their friends) than unfamiliar ones (strangers), with only one exception (men were better at recognizing the reactions of familiar targets than unfamiliar targets viewing pleasant slides). In their abilities to understand nonverbal cues, female friends showed resemblances to each other on all accuracy measures (pleasant/unpleasant/unusual X familiar/unfamiliar). Male friends resembled each other only in their understanding of the reactions of unfamiliar men viewing unpleasant slides.This research was supported in part by an NSF grant and an NIMH Research Scientist Development Award to the second author.

Health and Aging-in-Place: Implications for Community Practice

ABSTRACT

There is increasing interest in helping elders to remain independent in their homes. As the nation experiences the unprecedented growth among its oldest residents, public and private efforts are emerging to facilitate aging-in-place. However older people, particularly the oldest old, experience a myriad of issues impacting their health and ability to remain at home. This article presents the findings from a needs assessment of a Naturally Occurring Retirement Community (NORC) (n?=?114) that revealed multiple health-related issues among older people residing in high-need neighborhoods. The study utilized a holistic perspective of health to measure physical, mental, and social well-being among the older residents. Implications for community-based health interventions to enhance aging-in-place are discussed.     

Trauma-informed care training in a child welfare system: Moving it to the front line

The use of trauma-informed practices in the child welfare system is critically important to prevent system-induced trauma and encourage timely assessment, triage and referral for care when indicated. Ultimately, such measures have the potential over time to decrease the risk for mental health problems in children exposed to a trauma. This study evaluates an initiative in Arkansas to train child welfare front-line staff members in trauma-informed care practices. We evaluated the impact of the training on knowledge and use of trauma-informed care practices among three types of child welfare staff (Caseworkers, Program Assistants and Other front-line staff). Results suggest that this training process was highly successful in improving knowledge of trauma-informed care practices, especially among staff with the least formal education and training. We also found a significant increase in staff use of trauma-informed care practices at the three-month follow-up with little difference observed across staff groups. Barriers that may prevent staff from full implementation of training concepts are described and strategies to address barriers are proposed.
