Promoting comprehensive sun protection policies and practices in outdoor sports: a qualitative study of perceived priorities and practicalities

Sun protection policies, environments, practices, and attitudes in sporting club contexts might be significant determinants of sun exposure among adult sporting participants. Face-to-face interviews, using standardised, open-ended questions were conducted with 20 club officials from four sports: soccer, hockey, tennis and surf lifesaving. Thematic content analysis identified a number of salient themes. Formal sun protection policies were well-implemented in surf lifesaving, but less so in soccer, hockey and tennis clubs, which often had informal sun protection practices in place. Officials perceived sun protection to be important, which was related to perceived exposure levels, the type of sport, length of time played and the season. Consistent logistical and practical considerations emerged, including limited resources, availability of shade, and lack of control over sporting facilities, uniform regulations and games scheduling. Sun protection efforts often focused on children more than adult players. Reciprocal responsibility was an important theme, where it was perceived that responsibility for sun protection should be equally shared between the club and the member. In this study it was found that reciprocal responsibility, duty of care and sport-specific practical requirements might significantly influence the success of policy, environmental and education initiatives for sun protection in sporting settings.

Who is responsible for the protection of children? Implicit and explicit interpretations of marketing messages

In this paper, we examine ethical issues related to advertising to children in light of evidence that people can hold ‘implicit’ as well as ‘explicit’ consumer attitudes. From a review of the important features of implicit versus explicit attitudes, we hypothesise three important features of implicit consumer attitudes in children. First, we suggest they are likely to be acquired automatically from, in part, exposure to marketing messages. Second, we predict that these attitudes will be resistant to change through reflection or reason by the child or other person. Third, we hypothesise that children’s implicit consumer attitudes will be powerful predictors of their consumer choices in many situations. We discuss the implications for the ethics of marketing to children, and propose a research framework to begin investigating this important issue.

Including teachers as 'real' partners in child protection

Simultaneous downsizing of child protection services and increasing numbers of child abuse notifications often result in many notifications remaining un-investigated. One possible solution to this problem is to extend the capacity of the child protection system by delegating some of the tasks commonly undertaken by child protection workers to allied professionals. One such group of allied professionals is teachers. In the past, teachers have been recognised for their unique role in notifying suspicions of abuse, however, education professionals are often overlooked for their potential to contribute more than they currently do to child protection. In this paper we suggest that teachers can be included as 'real' and credible partners in the child protection process in a way not previously considered possible.

Influence of chromium content on the dry machining performance of cathodic arc evaporated TiA1N coatings

Physical vapour deposition (PVD) titanium aluminium nitride coated cutting tools are used extensively in global manufacturing for reducing production costs and improving productivity in a number of aggressive metal-cutting operations, namely, dry and high-speed machining. In this investigation, the performance of Ti1−xAlxN and Ti1−x−yAlxCryN coatings was assessed on Co-HSS twist drills used to machine grey cast iron. The failure criterion for drills was defined as a critical sized flank wear land at the outer corners of the drills. Using this criterion, the average tool life of uncoated twist drills was increased by factors of 2.5, 3.0 and 3.0 by Ti0.59Al0.41N, Ti0.27Al0.19Cr0.54N and Ti0.21Al0.14Cr0.65N coatings, respectively. Notwithstanding the similar increase in average tool life, the Ti1−x−yAlxCryN coatings produced more consistent results than the Ti1−xAlxN coated drills with standard deviations of 67, 3 and 19 holes, respectively. This result has significant practical implications in manufacturing, since drills are not replaced on an individual basis, but rather on a preset tool change frequency. The present paper discusses the performance of Ti1−xAlxN and Ti1−x−yAlxCryN coated drills in terms of average and practical drill life and concludes with remarks on the characterisation of PVD coatings and their significance on the performance of Co-HSS twist drills when dry machining grey cast iron.

Protection versus promotion: an empirical investigation

Using Turkish industry-level data from 1983 to 1990, we find that politically organized industries receive both higher protection and promotion than unorganized ones. Tariff rates are decreasing (increasing) in the import-penetration ratio and the absolute value of the import-demandelasticity for organized (unorganized) industries. Subsidy rates are decreasing (increasing) in the output-supply elasticity for organized (unorganized) industries. The results are consistent with the predictions of the Grossman–Helpman model and its extension in this paper. The mix of protection and promotion is inversely related to the ratio of their respective marginal deadweight cost measures.

Reducing the macroparticle content of cathodic arc evaporated TiN coatings

Cathodic arc evaporation (CAE) is a widely used technique for generating highly ionised plasma from which hard, wear-resistant PVD coatings can be deposited. A major drawback of this technique is the emission of micrometer-sized droplets of cathode material from the arc spot, which are commonly referred to as ‘macroparticles’. In this study, the effect of cathode poisoning was investigated as a method to reduce the number of macroparticles in PVD coatings. While the study focuses on the reduction of macroparticles in titanium nitride coatings, the outcomes and key findings can be broadly applied to the cathodic arc process, in particular, for the reduction of macroparticles in more advanced CAE coatings. The results support earlier findings that have shown that poisoning of the cathode can reduce the number of macroparticles emitted from the arc spot. The results of glow discharge optical emission spectroscopy (GD-OES) showed that the titanium content of the coatings varied little between the respective coatings despite changes in the deposition pressure from 0.1 to 1.2 Pa. The GD-OES results also showed the presence of oxide contamination at the surface of the coatings, which was significantly reduced with increasing deposition pressure. The coatings were also deposited onto high-speed steel twist drills to compare the metal-cutting performance when dry drilling a workpiece of cast iron. The results of the drill tests showed that tool life increased with a reduction in the number of macroparticles.

A comparison study of cerebral protection using Ginkgo biloba extract and Losartan on stroked rats

It has been well documented that oxidative stress is involved in stroke. Currently, many neuroprotective strategies have been targeted at molecules that are able to act as an oxidant to intervene with free-radical mediated apoptosis in the ischemic penumbra. In particular, natural products which contain antioxidant properties have undoubtedly efficacious for stroke treatment. In the current study, therapeutic effects of Ginkgo biloba extract (EGb) against cerebral protection in Wistar rats underwent middle cerebral artery occlusion (MCAO) was evaluated. A comparison study was conducted by using Losartan, an antihypertensive drug. Gene expression levels of pro-apoptotic genes (AT2 receptor, Fas, Bax and Bcl-xS) have shown to have significant reduction by EGb- and Losartan-treated groups as compared to vehicle group. Significant reduction of immunoreactivity of protein production of these genes, together with least nuclear green fluorescence observed in TUNEL, EGb, as an antioxidant drug, is concluded to have potent and promising therapeutic effect for stroke treatment.

Clinical supervision in child protection for community nurses

Community nurses have been recognized as having a key role in the protection and care of children, particularly in relation to the identification and detection of child abuse. In order to fulfill this role in a competent manner, they need to have access to appropriate supervision. The aim of this paper is to explore community nurses' and health care managers' understanding and experience of clinical supervision in child protection. The findings presented here were collected as part of a larger study commissioned by the Greater Glasgow Primary Health Care National Health Service (NHS) Trust. Ninety-nine nurses and nursing managers were interviewed, either individually or in groups, about their professional involvement in child protection issues and support for their involvement in child protection work, as well as their current knowledge and perceived training needs. The interview data was subjected to a thematic analysis. A lack of consensus was found among nurses and managers in Glasgow as to what constitutes clinical supervision and a good deal of variation in nurses' experiences of clinical supervision in the field of child protection. The historical difficulties with regard to supervision were attributed to several aspects of nursing culture. However, both nurses and managers emphasized the need for formal, regular, systematic supervision for all nurses regardless of their specific role with regard to child protection.
