Enabling Empowerment: The Role of Adults in ‘Youth Led’ Climate Groups

This research explores young people’s attitudes towards adult involvement within ‘youth led’ youth climate groups. Young people were acutely aware of their marginalisation and overall, there was a consensus that adults played a useful role as a resource, as experienced adult activists possessed knowledge that they lacked, or in offering practical support on legal issues or liaising with the police. The attitudes of young people to adult involvement is at times paradoxical in that whilst they were aware of its necessity, adults altered the dynamics of the groups, as there was a ‘power gap’ and that adult’s views could take precedence. As a result, on some occasions the young people parted ways from the adults. A continual theme from the research was that young people’s involvement in ‘youth climate groups’ gave them a sense of empowerment and they were much more aware of how to effect change, and to some extent they did need the support of adults in this process, often due to their structural disempowerment. The findings suggest that adult involvement was most successful when adults were committed to empowering young people and the researchers suggest that Kirshner’s model of ‘cycles of fading’ is a useful framework for adult involvement

‘You Don’t Get Ditched’—Young People’s Mental Health and Youth Work: Challenging Dominant Perspectives

This paper presents the findings of research focused on a youth work project which specializes in working with young people experiencing a variety of mental health issues, in the southwest of England. The qualitative data from the young people, youth workers, and stakeholders demonstrate the significance of a person-centered, asset-based approach to improving young people’s experiences with mental health. It provides a countervailing narrative to the dominant diagnostic and problematized focus of mental health services for young people. The research provides evidence that mental health for young people can be strengthened—even for those experiencing significant problems—through group work activities that develop resilience, confidence, and builds on their inherent strengths. This approach enables young people to develop their own responses to their problems rather than rely on external interventions that are orientated toward treatment. The research suggests that young people’s mental ill health in certain circumstances may well be improved by youth work rather than through a medicalized approach

A Common Cavity Coordinate System

In this report a coordinate system for cavities is defined. The purpose is to establish a standard for common use in order to avoid confusion while communicating features of certaincavities. By the help of this common system, information gained in different inspection processes can be easily compared. An additional projection, used during second sound measurements is introduced as well

Structure, Function, and Evolution of the Pseudomonas aeruginosa Lysine Decarboxylase LdcA

International audienceThe only enzyme responsible for cadaverine production in the major multidrug-resistant human pathogen Pseudomonas aeruginosa is the lysine decarboxylase LdcA. This enzyme modulates the general polyamine homeostasis, promotes growth, and reduces bacterial persistence during carbenicillin treatment. Here we present a 3.7-Å resolution cryoelectron microscopy structure of LdcA. We introduce an original approach correlating phylogenetic signal with structural information and reveal possible recombination among LdcA and arginine decarboxylase subfamilies within structural domain boundaries. We show that LdcA is involved in full virulence in an insect pathogenesis model. Furthermore, unlike its enterobacterial counterparts, LdcA is regulated neither by the stringent response alarmone ppGpp nor by the AAA+ ATPase RavA. Instead, the P. aeruginosa ravA gene seems to play a defensive role. Altogether, our study identifies LdcA as an important player in P. aeruginosa physiology and virulence and as a potential drug target

Registration for computer-navigated surgery in edentulous patients: A problem-based decision concept

BACKGROUND: Surgical navigation is a commonly used tool in cranio-maxillofacial surgery. Registration is the key element for precision, and a number of studies have shown different techniques to be accurate. Nonetheless, uncertainty surrounds the special situation in edentulous patients and a practical approach to what can be a challenging problem. MATERIALS AND METHODS: Four registration strategies for the Brainlab VectorVision(2) system are presented for surgical navigation of edentulous patients: three landmark-based, point-to-point techniques and one surface-based matching strategy are evaluated. RESULTS: The methods described differ in overall accuracy as well as in the region covered. In general, the more time-consuming and invasive the technique, the more precise it is. The non-invasive techniques are less precise, and they cover only small regions with sufficient accuracy. CONCLUSIONS: Taking into account which type of accuracy is clinically relevant and that the whole skull does not always need to be covered with the greatest possible accuracy, all the described techniques have their indications. The simpler and less invasive techniques can spare time, decrease costs, and harm patient. A decision tree is presented to the reader
