Hashtags Functions in the Protests Across Brazil

In this article, we discuss the communicative functions of hashtags during a period of major social protests in Brazil. Drawing from a theoretical background of the use of Twitter and hashtags in protests and the functions of language, we extracted a sample of 46,090 hashtags from 2,321,249 tweets related to Brazilian protests in June 2013. We analyzed the hashtags through content analysis, focusing on functions, and co-occurrences. We also qualitatively analyzed a group of 500 most retweeted tweets to understand the users’ tagging behavior. Our results show how users appropriate tags to accomplish different effects on the narrative of the protests

65-micron thin monocrystalline silicon solar cell technology allowing 12-fold reduction in silicon usage

Thin (<70 micron) single crystal silicon solar cells have been manufactured through the use of a novel process involving selective etching. Narrow grooves are micromachined through the wafer using a standard micromachining technique with cells manufactured on the resulting silicon strips. These bifacial cells have a much greater surface area than the original wafer, leading to dramatic decreases in processing effort and silicon usage. Individual cells fabricated using the new process have displayed efficiencies up to 17.5% while a 560cm2 prototype module has displayed an efficiency of 12.3%. The size, thickness and bifacial nature of the cells offer the opportunity for a wide variety of module architectures and applications

Theses and dissertations on the geology of Oregon : bibliography and index, 1899-1982

The present bibliography is the third compilation by the Oregon Department of Geology and Mineral Industries (DOGAMI) of theses and dissertations containing information on the geology of the state. It follows and incorporates the Bibliography of Theses on Oregon Geology by H.G. Schlicker (DOGAMI Miscellaneous Paper 7, 1959) and the Bibliography of Theses and Dissertations on Oregon Geology from January 1, 1959 to December 31, 1965, by M. Roberts (Supplement to DOGAMI Miscellaneous Paper 7, 1966). The considerable in­crease in the number of titles, from 137 in Schlicker and 70 in Roberts to the present 662 titles, reflects both the welcome growth of geologic study of the state and renewed attempts to improve the completeness of the older bibliographies. The years "1899-1982" in the title are meant to indicate that the listed titles are dated within this time span. We have not found any thesis dated before 1899; and we know that theses completed in most recent years, especially 1982, did not all come to our attention before this bibliography went to press. This compilation consists of an alphabetic list by author and an index map. Entries are numbered in sequence, and the index map is keyed to those numbers. For most theses, the numbers are placed on the map, as exactly as practicable, in the coun­ties, quadrangles, or quadrangle portions of the respective study areas. In those cases where the study area is too large or where the subject cannot be located geographically, the thesis numbers are listed under a few index categories on the map margin. The DOGAMI library maintains a growing collection of significant theses and dissertations for in-house use. About 56 percent of the titles listed here are currently in this collection. Abstracts of new acquisitions are periodically printed in DOGAMI's monthly magazine Oregon Geology. Apart from access through the libraries of degree-granting institutions, copies of many doctoral dissertations and a growing number of master's theses are available from University Microfilms Inter-national at Ann Arbor, Michigan. The compilation of this bibliography has been aided con­siderably by the information supplied by a great many geosci­ence departments in colleges and universities across the coun­try. We are deeply grateful to all of them for their cooperation

Beyond the Refugee Crisis how the UK news media represent asylum seekers across national boundaries

Migration is one of the most pressing, divisive issues in global politics today, and media play a crucial role in how communities understand and respond. This study examines how UK newspapers (n = 974) and popular news websites (n = 1044) reported on asylum seekers throughout 2017. It contributes to previous literature in two important ways. First, by examining the ‘new normal’ of daily news coverage in the wake of the 2015 ‘refugee crisis’ in Europe. Second, by looking at how asylum seekers from different regions are represented. The content analysis finds significant variations in how asylum seekers are reported, including terminology use and topics they are associated with. The paper also identifies important commonalities in how all asylum seekers are represented - most notably, the dominance of political elites as sources across all media content. It argues that Entman’s ‘cascade network model’ can help to explain this, with elites in one country able to influence transnational reports

Cues and knowledge structures used by mental-health professionals when making risk assessments

Background: Research into mental-health risks has tended to focus on epidemiological approaches and to consider pieces of evidence in isolation. Less is known about the particular factors and their patterns of occurrence that influence clinicians’ risk judgements in practice. Aims: To identify the cues used by clinicians to make risk judgements and to explore how these combine within clinicians’ psychological representations of suicide, self-harm, self-neglect, and harm to others. Method: Content analysis was applied to semi-structured interviews conducted with 46 practitioners from various mental-health disciplines, using mind maps to represent the hierarchical relationships of data and concepts. Results: Strong consensus between experts meant their knowledge could be integrated into a single hierarchical structure for each risk. This revealed contrasting emphases between data and concepts underpinning risks, including: reflection and forethought for suicide; motivation for self-harm; situation and context for harm to others; and current presentation for self-neglect. Conclusions: Analysis of experts’ risk-assessment knowledge identified influential cues and their relationships to risks. It can inform development of valid risk-screening decision support systems that combine actuarial evidence with clinical expertise

Configuring the PrEP user: Framing Pre-exposure Prophylaxis in UK newsprint 2012 – 2016

Pre-exposure prophylaxis (PrEP) has been hailed as a revolutionary intervention for HIV prevention. PrEP’s controversial status in the UK has generated significant media coverage. It is important to understand what role the media plays in framing PrEP policy issues. We undertook a qualitative analysis of UK newsprint articles between 2012 and 2016 to examine how PrEP was framed as a public health intervention up until a controversial policy decision not to provide PrEP in England. We identified how scientific evidence was deployed to shape two narratives: ir/responsible citizens focused on imagined PrEP users and their capacity to use PrEP effectively; and the public health imperative, which described the need for PrEP. Our analysis demonstrates the particular ways in which scientific evidence contributed to the certainty of PrEP as an effective intervention within UK newsprint. Scientific evidence also played a key role in framing PrEP as an intervention specifically for cis-gendered gay and bisexual men, playing into wider debates about who is a deserving patient and the appropriate use of public resources. Practitioners in the UK and elsewhere should be aware of these constructions of the PrEP user to ensure equitable access to PrEP beyond gay and bisexual men

'20 days protected learning' - students' experiences of an Overseas Nurses Programme - 4 years on: A retrospective survey

Background From September 2005 the Nursing and Midwifery Council (NMC) introduced new arrangements for the registration of non-EU overseas nurses which requires all applicants to undertake '20 days of protected learning' time in the UK and for some, a period of supervised practice. A survey was undertaken at Bournemouth University, which offers a '20 days protected learning only' programme, to elicit overseas nurses' demographic details, experiences in completing the programme and their 'final destinations' once registered. Methods An online survey was devised which contained a mixture of tick box and open ended questions which covered demographic details, views on the programme and final destinations This was uploaded to www.SurveyMonkey.com and sent out to nurses who had completed the Overseas Nurses Programme (ONP) with Bournemouth University (n=1050). Quantiative data were analysed using descriptive statistics and the qualitative data were coded and analysed using content analysis . Results There were 251 respondents (27.7% response rate). The typical 'profile' of a nurse who responded to the survey was female, aged 25-40 years and had been qualified for more than 5 years with a bachelors degree. The majority came from Australia on a 2 year working holiday visa and the key final destination in the UK, on registration with the NMC, was working for an agency. There were five key findings regarding experience of the programe. Of those surveyed 61.2% did not feel it necessary to undergo an ONP; 71.6% felt that they should be able to complete the programme on-line in their own country; 64.2% that the ONP should only contain information about delivery of healthcare in UK and Legal and professional (NMC) issues; 57% that European nurses should also undergo the same programme and sit an IELTS test; and 68.2% that the programme was too theory orientated; and should have links to practice (21%). Conclusions The NMC set the admissions criteria for entry to the register and Standards for an ONP. The findings of this survey raise issues regarding the percieved value and use of this approach for overseas nurses, and it may be helpful to take this into account when considering future policy
