Wu-Wei: Concept Analysis of a Conceptual Paradox.

The Taoist concept of wu-wei is explored through a concept analysis, as delineated by Walker and Avant. The paradoxical nature of wu-wei is explored through different uses, defining attributes, a model case, related and illegitimate cases, antecedents and consequences, and empirical referents. Practical applications for mental health nursing assessment and interventions are offered to show potential improved outcomes with the stance of wu-wei in practice.

Older adults' marijuana use, injuries, and emergency department visits.

Background: Despite increasing marijuana use among older adults, little research has been done on marijuana's effects on their healthcare use.

Objectives: To examine whether (1) marijuana use is associated with the likelihood of emergency department (ED) visits through increased injury risk, and (2) marijuana use patterns are associated with injury risk and ED visits among older adults.

Methods: Using the 2012-2013 National Epidemiologic Survey on Alcohol and Related Problems (N = 14,715 aged 50+; 6,379 men and 8,336 women), descriptive statistics were used to compare past-year marijuana users to nonusers on sociodemographic and physical/mental health characteristics.

Giordano Bruno and the heresy of many worlds.

This paper analyses the importance of Giordano Bruno's belief in many worlds, including the Moon, the planets and the stars, in the context of his trial by the Inquisitions in Venice and Rome. Historians have claimed that this belief was not heretical and therefore was not a major factor in Bruno's trial or execution. On the contrary, by examining neglected treatises on theology, heresies and Catholic canon law, I show that the belief in many worlds was formally heretical.

Contemporary Issues of Social Justice: A Focus on Race and Physical Education in the United States.

Ongoing events in the United States show the continual need to address issues of social justice in every social context. Of particular note in this article, the contemporary national focus on race has thrust social justice issues into the forefront of the country's conscious. Although legal segregation has ran its course, schools and many neighborhoods remain, to a large degree, culturally, ethnically, linguistically, economically, and racially segregated and unequal (Orfield & Lee, 2005).

Predictors of attrition from an expressive writing intervention for sexual abuse survivors.

This study examined predictors of attrition from a clinical trial examining the effects of an expressive writing intervention for sexual problems among female survivors of child sexual abuse. Participants were 124 women all reporting sexual difficulties, who were randomized to a trauma-focused condition (n = 45), an experimental sexual schema-focused condition (n = 37), or a control condition (n = 42). Thirty-five women (28%) dropped out before completing posttreatment assessments.

Category and Position Competition in Free Recall.

The present two experiments were designed to investigate the effects of two competing retrieval strategies-category and position cueing. One hundred college students participated in Experiment I in which Presentation Rate, List Type, and Stimulus Position were manipulated within an FR paradigm. Sixty students participated in Experiment II in which Formal Response Similarity and Stimulus Position were manipulated within a PA paradigm.
