Clear Yet Crossed: Athletes' Retrospective Reports of Coach Violence.

AIMS: This study aimed at examining coach-athlete violence based on the retrospective reports of adults who had been athletes as children and adolescents; predict variables that contribute to the existence of such violence; describe difficulties that the participants encountered as young athletes following such violence; and reveal the outcomes of such violence on their emotions and behaviors, in the past and present. METHODOLOGY: The applied mixed methods comprised quantitative self-reporting questionnaires and qualitative interviews. The former included 440 participants (mean age 27.6) who had trained for at least one year in a sports union youth department; the latter included 14 participants (aged 23-37). These competitive athletes came from eight branches of sports. The interviews were analyzed based on the Narrative Approach. RESULTS: According to the quantitative study, all participants had experienced coach violence at least once during their career, mainly psychological violence and neglect, followed by physical violence. Sexual violence was least reported. The age of their retirement from sports and the number of coaches that they had had were significant predictors of violence. Thematic analysis of the qualitative interviews resulted in six types of coach-athlete violence: (1) psychological violence; (2) verbal violence; (3) starvation and food fattening; (4) non-proportional punishing; (5) physical violence; and (6) sexual violence. CONCLUSIONS: It is vital that coach-athlete violence is addressed in public discourse, that the topic of young athletes' safety is introduced into coaching education, and that a position holder is nominated to be in charge of such safety in all sports organizations.

How Can Governmental Positive Power Decrease Violence in Crime-Oriented Arenas? The Case of English Football.

This article will survey the dramatic change English football had undergone since the end of the last century. The authors will closely explore the implementation of the Taylor Report recommendations, to convince that which power and management techniques were used to decrease violence in public areas that were previously considered dangerous and crime-oriented. It will be argued that disciplinarian techniques were practiced, much like those described in Foucault's Discipline and Punish, while this very power has proven to be positive and revitalizing. It will be therefore concluded that power is at its most effective when operated via techniques of discipline and social inclusion. These arguments correspond with the positive criminology theory whose popularity within the discipline is gradually increasing.

Inhibition of ice growth and recrystallization by zirconium acetate and zirconium acetate hydroxide.

The control over ice crystal growth, melting, and shaping is important in a variety of fields, including cell and food preservation and ice templating for the production of composite materials. Control over ice growth remains a challenge in industry, and the demand for new cryoprotectants is high. Naturally occurring cryoprotectants, such as antifreeze proteins (AFPs), present one solution for modulating ice crystal growth; however, the production of AFPs is expensive and inefficient. These obstacles can be overcome by identifying synthetic substitutes with similar AFP properties. Zirconium acetate (ZRA) was recently found to induce the formation of hexagonal cavities in materials prepared by ice templating. Here, we continue this line of study and examine the effects of ZRA and a related compound, zirconium acetate hydroxide (ZRAH), on ice growth, shaping, and recrystallization. We found that the growth rate of ice crystals was significantly reduced in the presence of ZRA and ZRAH, and that solutions containing these compounds display a small degree of thermal hysteresis, depending on the solution pH. The compounds were found to inhibit recrystallization in a manner similar to that observed in the presence of AFPs. The favorable properties of ZRA and ZRAH suggest tremendous potential utility in industrial applications.

Monitoring the HIV-1 integrase enzymatic activity using atomic force microscopy in a 2LTR system.

Integration of the HIV cDNA into the host chromosome is a key event in the viral replication cycle. It is mediated by the viral integrase (IN) enzyme, which is an attractive anti-HIV drug target. Here we present the first AFM imaging of IN-mediated DNA integration products in a two-LTR system.
