    The role of second-neighbor effects in photoemission: Are silicon surfaces and interfaces special?

    Full text link
    A widely used assignment scheme for Si 2p2p core-level photoemission studies of silicon oxidation relies solely on the formal oxidation state of the silicon. The tacit assumption of this assignment methodology is that second-neighbor effects have no measurable effect on observed Si 2p2p binding energies. In this letter, new experiments are combined with literature precedents to make the case that the second-neighbor effects play an important role in determining binding energy shifts.

    Assigning stranded bottlenose dolphins to source stocks using stable isotope ratios following the Deepwater Horizon oil spill

    The potential for stranded dolphins to serve as a tool for monitoring free-ranging populations would be enhanced if their stocks of origin were known. We used stable isotopes of carbon, nitrogen, and sulfur from skin to assign stranded bottlenose dolphins Tursiops truncatus to different habitats, as a proxy for stocks (demographically independent populations), following the Deepwater Horizon oil spill. Model results from biopsy samples collected from dolphins from known habitats (n = 205) resulted in an 80.5% probability of correct assignment. These results were applied to data from stranded dolphins (n = 217), resulting in predicted assignment probabilities of 0.473, 0.172, and 0.355 to Estuarine, Barrier Island (BI), and Coastal stocks, respectively. Differences were found west and east of the Mississippi River, with more Coastal dolphins stranding in western Louisiana and more Estuarine dolphins stranding in Mississippi. Within the Estuarine East Stock, 2 groups were identified, one predominantly associated with Mississippi and Alabama estuaries and another with western Florida. Ī“15N values were higher in stranded samples for both Estuarine and BI stocks, potentially indicating nutritional stress. High probabilities of correct assignment of the biopsy samples indicate predictable variation in stable isotopes and fidelity to habitat. The power of Ī“34S to discriminate habitats relative to salinity was essential. Stable isotopes may provide guidance regarding where additional testing is warranted to confirm demographic independence and aid in determining the source habitat of stranded dolphins, thus increasing the value of biological data collected from stranded individuals.Publisher PDFPeer reviewe

    The development of the British Red Cross' psychosocial framework: 'calmer'

    Get PDF
    This paper presents the history, development and approach of the new psychosocial framework which in 2008 was adopted by the British Red Cross, and a piece of research designed to review its fitness for purpose as an educational tool. The framework CALMER is a single, overarching approach for considering and delivering psychosocial services across all of the British Red Cross. It is being included in all relevant training programmes, such as within first aid and psychosocial support and within services in emergency response, event first aid, health and social care, international tracing and message and refugee services and across human resources. The framework includes six prompts which should be followed sequentially, with guidance on facilitative behaviours within each. The research considered the levels of confidence and worry of participants on one day training programmes delivered to three different groups of personnel in three different countries. While finding support for the CALMER framework, further recommendations are made for future research

    Challenges and Opportunities in Sourcing, Preparing and Developing a Teaching Force for the UAE

    Teacher education occurs along a continuum that encompasses teacher candidate recruitment, teacher candidate preparation, novice teacher induction, teacher professional development, and advanced teacher qualifications. Since the formation of the state in 1971, teacher recruitment and teacher education in the UAE have undergone several stages of development, beginning with the sourcing of teachers from the Arab world, through the establishment of in-country teacher education programs designed to produce native teachers, to the hiring of teachers from high performing school systems in the Anglophone world. Teacher education is quite a challenging enterprise, being impacted by changes in the constantly evolving education system in this young nation. High-quality teacher education candidates can be elusive, and it is difficult to attract nationals to teaching, especially males. Yet, at the same time, there are opportunities for teacher education as the country works valiantly to raise educational standards, including the development of Arabic language teacher education, the provision of continuing professional development around teacher licensure, and induction programs for novice teachers

    Internet-based prevention of posttraumatic stress symptoms in injured trauma patients: design of a randomized controlled trial.

    Get PDF
    Background: Injured trauma victims are at risk of developing Posttraumatic Stress Disorder (PTSD) and other post-trauma psychopathology. So far, interventions using cognitive behavioral techniques (CBT) have proven most efficacious in treating early PTSD in highly symptomatic individuals. No early intervention for the prevention of PTSD for all victims has yet proven effective. In the acute psychosocial care for trauma victims, there is a clear need for easily applicable, accessible, cost-efficient early interventions. Objective: To describe the design of a randomized controlled trial (RCT) evaluating the effectiveness of a brief Internet-based early intervention that incorporates CBT techniques with the aim of reducing acute psychological distress and preventing long-term PTSD symptoms in injured trauma victims. Method: In a two armed RCT, 300 injured trauma victims from two Level-1 trauma centers in Amsterdam, the Netherlands, will be assigned to an intervention or a control group. Inclusion criteria are: being 18 years of age or older, having experienced a traumatic event according to the diagnostic criteria of the DSM-IV and understanding the Dutch language. The intervention group will be given access to the intervention's website (www.traumatips.nl), and are specifically requested to login within the first month postinjury. The primary clinical study outcome is PTSD symptom severity. Secondary outcomes include symptoms of depression and anxiety, quality of life, and social support. In addition, a cost-effectiveness analysis of the intervention will be performed. Data are collected at one week post-injury, prior to first login (baseline), and at 1, 3, 6 and 12 months. Analyses will be on an intention-to-treat basis. Discussion: The results will provide more insight into the effects of preventive interventions in general, and Internet-based early interventions specifically, on acute stress reactions and PTSD, in an injured population, during the acute phase after trauma. We will discuss possible strengths and limitations

    Police officers and post traumatic stress disorder: discussing the deficit in research, identification and prevention in England and Wales

    Get PDF
    This article will review available literature regarding Post Traumatic Stress Disorder (PTSD) within policing in England and Wales, with a particular focus on its early identification and prevention. An overview of PTSD will be given as well as an exploration of why police officers are potentially more susceptible to this mental health condition compared to other members of society. Key factors in the early identification and prevention of PTSD will be outlined, with a focus on crisis intervention techniques which have been subject to considerable academic study. There is limited research available from England and Wales that looks specifically at PTSD in policing, this research deficit will be highlighted and key areas of research which need to be explored further will be given so that this problem can be both identified and prevented in officers
