The production and deployment of an on-line video learning bank in a skills training environment

This paper describes the introduction of videos as aids in clinical skills teaching. Although the process explored focuses on a nursing clinical skills environment it is relevant to many other disciplines. With the introduction of the pre-registration degree in nursing in Ireland in 2002, the formerly hospital-based schools of nursing amalgamated into larger programmes with their affiliated higher education institutes (HEIs). The result was a considerable increase in class sizes. The current average annual cohort in the School of Nursing, Dublin City University (DCU) is 240 students. This has resulted in a need to review the way we teach clinical skills on campus. These skills form a large part of the programme and are taught to students in the school-based simulated nursing environment to prepare them for their practical experience in the clinical environment. Until 2006 the skills had been taught to groups of 25-30 students using a demonstration and practice technique. This teaching method has posed a number of problems: •Learning experiences vary depending on the mix of demonstration and practice in each session. •It can be difficult for students to absorb all of the information presented in a single demonstration. •It is highly resource intensive. It was decided that video technology incorporating a large scale deployment of skills videos over a video web server, in conjunction with a shift in emphasis in the teaching contact sessions could offer a useful tool to aid the teaching process. This paper will discuss the production process, the implementation of the project in the teaching environment and the evaluation findings

Dancing Up the Glass Escalator: Institutional Advantages for Men in Ballet Choreography

A dearth of women exists in the upper echelons of ballet choreography. Both academia and the popular press have noted and documented this phenomenon. For instance, in “Breaking the Glass Slipper,” New York Times journalist Michael Cooper recently noted, “When it comes to choreography, at least at most major companies, ballet remains overwhelmingly a man’s world” [1]. Similarly, critic Luke Jennings has noted, “In professional ballet companies, faced with heavier workloads and greater competitive stress than their male colleagues (not to mention the exigencies of pointe work), few women have the time, energy or inclination to consider choreography” [2]. And yet many arguments (such as Jennings’) as to why women do not become choreographers reflect back on women in ballet – claiming a lack of interest, ambition, or even ability – and fail to acknowledge the structural and systemic inequities that promote men in ballet at the expense of their female peers. Even women choreographers themselves tend to claim that women do not become choreographers because of their own choices, constraints, etc., instead of citing systemic structures of unequal opportunity [3]. Failing to acknowledge institutional inequality places the fault of discrimination upon its victims, and ignores the gendered hierarchy within ballet institutions. As an alternative, situating ballet choreography in the context of sociological theory can shed light on how institutions promote token men in ballet to artistic leadership positions, and may help disprove the notion that women do not become choreographers simply because of cultural reasons that relate back to the women themselves

Resource and physiological constraints on global crop production enhancements from atmospheric particulate matter and nitrogen deposition

Changing atmospheric composition, induced primarily by industrialization and climate change, can impact plant health and may have implications for global food security. Atmospheric particulate matter (PM) can enhance crop production through the redistribution of light from sunlight to shaded leaves. Nitrogen transported through the atmosphere can also increase crop production when deposited onto cropland by reducing nutrient limitations in these areas. We employ a crop model (pDSSAT), coupled to input from an atmospheric chemistry model (GEOS-Chem), to estimate the impact of PM and nitrogen deposition on crop production. In particular, the crop model considers the resource and physiological restrictions to enhancements in growth from these atmospheric inputs. We find that the global enhancement in crop production due to PM in 2010 under the most realistic scenario is 2.3, 11.0, and 3.4 % for maize, wheat, and rice, respectively. These crop enhancements are smaller than those previously found when resource restrictions were not accounted for. Using the same model setup, we assess the effect of nitrogen deposition on crops and find modest increases (∼ 2 % in global production for all three crops). This study highlights the need for better observations of the impacts of PM on crop growth and the cycling of nitrogen throughout the plant–soil system to reduce uncertainty in these interactions

Aceite de oliva y la hemostasia

Olive oil is a key component of the traditional Mediterranean diet; a diet that may explain the low rate of cardiovascular disease (CVD) in Southern European. (Extra virgin) Olive oil is a good source of monounsaturated fatty acids (MUFA) and phenolic compounds, both of which have been investigated for their effects on plasma lipids and lipoproteins, measures of oxidation and factors related to thrombosis. This issue aims to summarise the current understanding of the effects of such dietary components on the haemostatic system and subsequent risk of CVD. To date, evidence suggests that diets rich in MUFA and thus in olive oil attenuate the thrombotic response via a reduction in platelet aggregation and in postprandial FVII levels. Thrombosis is a key event in causing heart attacks and strokes, which if modulated by diet could pose a cost-effective way of reducing CVD incidence in populations that adhere to MUFA/olive oil-rich diets long-term.El aceite de oliva es un componente esencial de la dieta Mediterránea que puede explicar el bajo índice de enfermedad cardiovascular (CVD) en los países del sur de Europa. El aceite de oliva (extra virgen) es una fuente de ácidos grasos monoinsaturados (MUFA) y de compuestos fenólicos, de gran interés por sus efectos, entre otros, sobre las lipoproteínas y los lípidos plasmáticos, su capacidad antioxidante y su papel en la expresión de factores relacionados con la trombosis. En este capítulo se presenta un resumen del conocimiento actual sobre la influencia derivada del consumo de aceite de oliva (extra virgen) en el sistema hemostático y el riesgo de CVD. Por ahora se sabe que dietas ricas en MUFA (aceite de oliva) pueden atenuar la respuesta trombótica mediante la reducción de la agregación plaquetaria y de las concentraciones postprandiales del factor VII de coagulación (FVII). La trombosis es un evento relevante en los ataques al corazón y el ictus, de manera que su modulación con la dieta puede constituir una forma rentable para la disminución de la incidencia de CVD en poblaciones que consumen dietas enriquecidas en MUFA/aceite de oliva durante largo tiempo

The production and deployment of an on-line video learning bank in a skills training environment

Context and Background: Nursing students are taught many skills to prepare them for their practical experience in the clinical environment. To date these skills have been taught to students using a demonstration and practice technique. This teaching method has a number of disadvantages: - it is highly resource intensive - learning experiences vary depending on the mix of demonstration and practice in each session - it can be difficult for students to absorb all of the information presented in a single demonstration. It was decided that video technology incorporating the deployment of a skills video bank over a web server, in conjunction with a shift in emphasis in the teaching contact sessions could provide a useful tool to aid the teaching process. Aim of the paper The aim of the paper is to disseminate our experiences of producing a large scale audiovisual learning package. The Production Process The first step involved the production of a video demonstrating a particular clinical skill, aseptic technique. This replaced the demonstration element of the skills session. Students viewed it online before the skills session and then spent the time allotted to this skill practising it under supervision. It was evaluated positively by students and the lecturer involved. As a result, a bank of 17 more videos focussing on fundamental skills within one first year module was developed in-house. The main focus of this paper will be on the production processes involved in this and its introduction into teaching practice

News media framing of food poverty and insecurity in high-income countries: A rapid review

Food poverty and insecurity have become a public health emergency in many high-income countries. News media coverage can shape public and political views towards such issues. This rapid review synthesizes the evidence on how food poverty and insecurity are represented in the news media. Peer-reviewed publications were accessed through three electronic databases, with reference lists of all included studies screened. Primary research studies conducted in high-income countries and published in English since 1995 were included, with no restrictions on study methods. A combination of deductive coding to Entman's framing theory and inductive analysis was used. Ten studies, mostly rated as low quality, were included in the review. Newspapers were the only type of news media examined. The findings showed a largely absent nuanced understanding of food poverty and insecurity, with the problem often defined by food bank use and the consequences mainly focused on physical health. The causes were mostly attributed to structural factors, with the solutions largely focused on charitable food aid. The discourse of recipient (un)deservingness of food aid was evident. Articles often contained views from government officials and charities, with individuals' experiences of food poverty and insecurity largely absent. The findings of this review highlight that a major shift in print media discourse on food poverty and insecurity is required. More balanced and critical news reporting is required to present a more realistic picture of food poverty and insecurity, including its multi-dimensional nature, limitations of food charity and the need for structural solutions to this important issue.</p

Nitrite cycling in the primary nitrite maxima of the eastern tropical North Pacific

The primary nitrite maximum (PNM) is a ubiquitous feature of the upper ocean, where nitrite accumulates in a sharp peak at the base of the euphotic zone. This feature is situated where many chemical and hydrographic properties have strong gradients and the activities of several microbial processes overlap. Near the PNM, four major microbial processes are active in nitrite cycling: ammonia oxidation, nitrite oxidation, nitrate reduction and nitrite uptake. The first two processes are mediated by the nitrifying archaeal/bacterial community, while the second two processes are primarily conducted by phytoplankton. The overlapping spatial habitats and substrate requirements for these microbes have made understanding the formation and maintenance of the PNM difficult. In this work, we leverage high-resolution nutrient and hydrographic data and direct rate measurements of the four microbial processes to assess the controls on the PNM in the eastern tropical North Pacific (ETNP). The depths of the nitrite maxima showed strong correlations with several water column features (e.g., top of the nitracline, top of the oxycline, depth of the chlorophyll maximum), whereas the maximum concentration of nitrite correlated weakly with only a few water column features (e.g., nitrate concentration at the nitrite maximum). The balance between microbial production and consumption of nitrite was a poor predictor of the concentration of the nitrite maximum, but rate measurements showed that nitrification was a major source of nitrite in the ETNP, while phytoplankton release occasionally accounted for large nitrite contributions near the coast. The temporal mismatch between rate measurements and nitrite standing stocks suggests that studies of the PNM across multiple timescales are necessary.</p
