A Meta‐Analysis of Parent–Adolescent Conflict: Disagreement, Hostility, and Youth Maladjustment

Abstract: Parent–adolescent conflict is a normative characteristic of adolescence. However, research findings have been inconsistent, and the relative contributions of specific dimensions of parent–adolescent conflict (disagreement and hostility) to youth maladjustment are unknown. This meta-analysis synthesized the literature on parent–adolescent conflict and distinguished disagreement, hostility, and composite measures of disagreement and hostility. A multilevel model was utilized to analyze 401 effects from 52 studies. Results indicate that parent–adolescent conflict is positively associated with youth maladjustment. The strength of this association varied as a function of youth maladjustment dimensions but not conflict dimensions. The association between parent–adolescent conflict and youth maladjustment also varied by youth gender and by longitudinal versus cross-sectional design. Results suggest that both disagreement and hostility in parent–adolescent relationships have negative effects on youth development.

A Cooperative Caching Scheme Based on Mobility Prediction in Vehicular Content Centric Networks

Abstract: Vehicular content centric networks (VCCNs) emerge as a strong candidate to be deployed in information-rich applications of vehicular communications. Due to vehicles’ mobility, it becomes rather inefficient to establish end-to-end connections in VCCNs. Consequently, content packets are usually sent back to the requesting node via different paths in VCCNs. To improve network performance of VCCNs, node mobility should be exploited for vehicles to serve as relays and to carry data for delivery. In this paper, we propose a scheme called cooperative caching based on mobility prediction (CCMP) for VCCNs. The main idea of CCMP is to cache popular contents at a set of mobile nodes that may visit the same hot spot areas repeatedly. In our CCMP scheme, we use prediction based on partial matching to predict mobile nodes’ probability of reaching different hot spot regions based on their past trajectories. Vehicles with longer sojourn time in a hot region can provide more services and should be preferred as caching nodes. To solve the problem of limited buffer at each node, we design a cache replacement based on content popularity to guarantee that only popular contents are cached. We evaluate CCMP through the opportunistic network environment simulator for its salient features in success ratio and content access delay compared to other state-of-the-art schemes.

Delay or rate of food delivery as a determiner of response rate

Abstract: Pigeons were confronted with two keys: a green food key and a white changeover key. Food became available for a peck to the green key after variable intervals of time (mean = 113 seconds). A single peck on the changeover key changed the color of the food key to red for a fixed period of time during which the timing of the variable-interval schedule in green was suspended and the switching option eliminated and after which the conditions associated with green were reinstated. In Experiment 1 a single food presentation was obtainable during each red-key period after a minimum delay timed from the switch. This delay and the duration of the red-key period were held constant during a condition but varied between conditions (delay = 2.5, 7.5, 15, or 30 seconds; red-period duration = 30, 60, 120, 240, or 480 seconds). In Experiment 2 additional food presentations were scheduled during a 240-second red-key period with the delay to the first food delivery held constant at 30 seconds, and the delays to later food deliveries varied over conditions. Considering the data from both experiments, the rate of switching to red was a decreasing function of the delay to the first food, the delay to the second food, and perhaps the delay to the third food after a switch. There was no clear evidence that the rate of food in the red-key period made an independent contribution. The ordering of response rates among conditions was consistent with the view that each food presentation after a response adds an incremental effect to the rate of the response and that each food presentation's contribution is a decreasing function of its delay timed from the response.

A nursing manifesto: An emancipatory call for knowledge development, conscience, and praxis

Abstract: The purpose of this paper is to present the theoretical and philosophical assumptions of the Nursing Manifesto, written by three activist scholars whose objective was to promote emancipatory nursing research, practice, and education within the dialogue and praxis of social justice. Inspired by discussions with a number of nurse philosophers at the 2008 Knowledge Conference in Boston, two of the original Manifesto authors and two colleagues discussed the need to explicate emancipatory knowing as it emerged from the Manifesto. Our analysis yielded an epistemological framework based on liberation principles to advance praxis in the discipline of nursing. This paper adds to what is already known on this topic, as there is not an explicit contribution to the literature of this specific Manifesto, its significance, and utility for the discipline. While each of us have written on emancipatory knowing and social justice in a variety of works, it is in this article that we identify, as a unit of knowledge production and as a direction towards praxis, a set of critical values that arose from the emancipatory conscience-ness and intention seen in the framework of the Nursing Manifesto.

Post‐Degree Supervision: Existing and Preferred Practices

Abstract: A survey of National Certified Counselors (NCCs) was conducted to (a) document existing supervision practices and (b) determine the type of supervision these counselors preferred at this point in their careers. Descriptive statistics and chi-square analyses were conducted for the total sample (N=357) and subgroups classified by work setting, counseling experience, degree level, and hours of post-degree supervision. Results indicated that existing practices varied, with school-based respondents receiving the least supervision. A majority of respondents said that they currently were being supervised by noncounseling professionals. Almost every respondent wanted some supervision, and most preferred a supervisor who had additional training in supervision.
