Development of automated tools based on electronic identification for the improvement of organic livestock production systems

Technical constraints of livestock production in organic farming systems are numerous and require more attention than in conventional systems. The implementation of individual electronic identification that is planned in Europe offers the possibility of developing automated devices that may be well adapted to the practices of organic breeders. We developed an automated mounting detector, carried by a male, which makes it possible to detect any female in oestrus. Hence, this device is the unique solution for inseminating females when they are fertile, thus ensuring links with selection programmes. The second device developed is a dynamic sorting door based on respect for animal behaviour, preventing stress by allowing animals not to be unnecessarily confined. When associated with an electronic weighing device, it offers the possibility of adapting health treatments to the appropriate animals, in agreement with organic breeding specifications. Finally, electronic identification combined with GPS offers the breeder the possibility of simplifying the certification of animals in areas converted to organic farming. We believe that these technologies may greatly reduce the workload of breeders while improving animal welfare

Conceptualising knowledge for access in the sciences: academic development from a social realist perspective

Whilst arguing from a social realist perspective that knowledge matters in academic development (AD) curricula, this paper addresses the question of what knowledge types and practices are necessary for enabling epistemological access. It presents a single, in-depth, qualitative case study in which the curriculum of a science AD course is characterised using Legitimation Code Theory (LCT). Analysis of the course curriculum reveals legitimation of four main categories of knowledge types along a continuum of stronger to weaker epistemic relations: disciplinary knowledge, scientific literacies knowledge, general academic practices knowledge and everyday knowledge. These categories are ‘mapped’ onto an LCT(Semantics)(how meaning relates to both context and empirical referents) topological plane to reveal a curriculum that operates in three distinct but interrelated spaces by facing towards both the field of science and the practice of academia. It is argued that this empirically derived differentiated curriculum framework offers a conceptual means for considering the notion of access to ‘powerful’ knowledge in a range of AD and mainstream contexts

Becoming a Performance Analyst : Autoethnographic Reflections on Agency, and Facilitated Transformational Growth

This is an Accepted Manuscript of an article published by Taylor & Francis Group in Reflective Practice, on 3 September 2014, available online at: http://dx.doi.org/10.1080/14623943.2014.900014.This paper features an autoethnographic approach in presenting and reflecting upon the story of one higher education student’s rapid vocational and academic transformation. Initially an inconspicuous undergraduate student, Andrew experienced an accelerated development that catapulted him to working in elite sport performance analysis (PA) environments, within a year. PA is a sub-discipline of sports coaching that involves using the latest technological advances to influence sporting performance, through the objective analysis of performance data. This autoethnographic piece is partly Andrew’s personal reflection upon that journey towards his newfound profession, which initially grew out of his experience of a generic sports degree at a university. Through stepping out of his comfort zone, and analysing sports previously unknown to him, extraordinary progress was made, and various vocational and academic opportunities arose. The initial catalyst for this developmental journey was facilitated by coaching lecturer David, who reflects upon how Andrew’s story links to his own educational philosophies. Andrew and David explore what these stories might mean to them personally, including potential links to the metaphor of learning as becoming, and notions around the concepts of learner agency, and educational facilitation. The paper ends by exploring the theoretical frameworks that guided this paper’s structure and focusPeer reviewedFinal Accepted Versio

The necessity and possibility of powerful ‘regional’ knowledge: curriculum change and renewal

© 2016 Taylor & Francis. The paper argues that powerful regional knowledge is necessary and possible and that there are historical precedents supporting these claims. Regional knowledge is being used in a double sense: the first Bernsteinian, the second in relation to knowledge generated outside the academy. Both are important if the debate is not to be confined solely to the global north and if the curriculum is to be responsive to geo-political realities. In order to think critically about access to higher education, we need to consider the sorts of knowledge, engagement, and opportunities that are open to newer actors. This includes recognising the contextual nature of professional practice and also that social movements beyond the academy can and do challenge academic knowledge. The paper concludes that many of issues addressed are not capable of theoretical resolution alone and that we need more empirical work to inform curriculum change and renewal

Myopia and misrecognition : the impact of managerialism on the management of compliance

This article explores the construction of a particular form of compliance in probation practice during a period in which policy shifted from enforcement towards compliance. The article uses four concepts from Bourdieu's field theory (habitus, field, misrecognition and symbolic violence) to highlight the way in which the shift in policy was attuned to the subjective structure of probation practitioners' habitus but resulted in a form of compliance which was myopic in nature and thus did not adhere to what we know about habitus in probation from other research. The article explores this phenomenon through Bourdieu's notion of misrecognition suggesting that whilst the policy change was regarded generally positively, it is an example of 'symbolic violence'. In turn, this tells us about practitioners' position in the field which is useful in terms of future analyses of how changes to the delivery of community sanctions will manifest in the coming years

Less is more: Antibiotics at the beginning of life

Antibiotic exposure at the beginning of life can lead to increased antimicrobial resistance and perturbations of the developing microbiome. Early-life microbiome disruption increases the risks of developing chronic diseases later in life. Fear of missing evolving neonatal sepsis is the key driver for antibiotic overtreatment early in life. Bias (a systemic deviation towards overtreatment) and noise (a random scatter) affect the decision-making process. In this perspective, we advocate for a factual approach quantifying the burden of treatment in relation to the burden of disease balancing antimicrobial stewardship and effective sepsis management

Management and resistance in the digital newsroom

What happens when there is conflict between the profit motivations of a news outlet and the professional values of its journalists? Questions of managerial influence and journalistic autonomy have interested media scholars from the seminal work of Warren Breed onwards. However, there have only been a handful of studies since the introduction of audience metrics which, this research suggests, allow managers to more efficiently monitor and discipline their journalists. This article presents an ethnographic case study of a Reuters newswire bureau during a time of conflict between the management and journalists. The article outlines the strategies that management used to incentivize their journalists to change their reporting priorities. These included the strategic dissemination of audience metrics and praise, and the hiring and promotion of ‘appropriate’ journalists to positions of influence. These interventions changed who was considered a ‘good journalist’ at the newswire, disrupting existing hierarchies, and eventually changing the culture of the newsroom. The article draws on the insights of Pierre Bourdieu’s field theory to help explain how managerial power operates, and the role that individual journalists play producing and reinforcing newsroom norms

Claw and limb disorders in 12 Norwegian beef-cow herds

<p>Abstract</p> <p>Background</p> <p>The main aim of the study was to assess the prevalence of claw and limb disorders in Norwegian beef-cow herds.</p> <p>Methods</p> <p>Twenty-six herds with ≥15 cow-years were selected by computerized systematic assignment from the three most beef cattle-dense regions of Norway. The study population consisted of 12 herds with 28 heifers and 334 cows. The animals were trimmed and examined once by claw trimmers during the late winter and spring of 2003. The seven claw trimmers had been taught diagnosing and recording of claw lesions. Environment, feeding and management routines, age and breed, culling and carcass characteristics were also recorded.</p> <p>Results</p> <p>Lameness was recorded in 1.1% of the animals, and only in hind claws. Pericarpal swellings were recorded in one animal and peritarsal lesions in none. In total, claw and limb disorders including lameness were recorded in 29.6% of the animals, 4.1% with front and 28.2% with hind limb disorders, respectively. Most lesions were mild. Laminitis-related claw lesions were recorded in 18.0% of the animals and infectious lesions in 16.6%. The average claw length was 84 mm in front claws and 89 mm in hind claw. Both laminitis-related and infectious claw lesions were more prevalent with increasing age. Carcasses from animals with claw and limb disorders were on average 34 kg heavier than carcasses from animals without such disorders (p = 0.02). Our results also indicate association between some management factors and claw lesions.</p> <p>Conclusion</p> <p>The study shows that the prevalence of lameness was low in 12 Norwegian beef-cow herds compared to beef-cattle herds in other countries and also that there were less claw and limb disorders in these herds compared to foreign dairy-cattle herds. The prevalence of lameness and white-line fissures was approximately the same as in Norwegian dairy herds whereas less dermatitis, heel-horn erosions, haemorrhages of the sole and the white line and sole ulcers were recorded.</p

Metabolomic-Based Noninvasive Serum Test to Diagnose Nonalcoholic Steatohepatitis: Results From Discovery and Validation Cohorts

Nonalcoholic fatty liver disease (NAFLD) is the most common type of chronic liver disease worldwide and includes a broad spectrum of histologic phenotypes, ranging from simple hepatic steatosis or nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis (NASH). While liver biopsy is the reference gold standard for NAFLD diagnosis and staging, it has limitations due to its sampling variability, invasive nature, and high cost. Thus, there is a need for noninvasive biomarkers that are robust, reliable, and cost effective. In this study, we measured 540 lipids and amino acids in serum samples from biopsy-proven subjects with normal liver (NL), NAFL, and NASH. Using logistic regression analysis, we identified two panels of triglycerides that could first discriminate between NAFLD and NL and second between NASH and NAFL. These noninvasive tests were compared to blinded histology as a reference standard. We performed these tests in an original cohort of 467 patients with NAFLD (90 NL, 246 NAFL, and 131 NASH) that was subsequently validated in a separate cohort of 192 patients (7 NL, 109 NAFL, 76 NASH). The diagnostic performances of the validated tests showed an area under the receiver operating characteristic curve, sensitivity, and specificity of 0.88 +/- 0.05, 0.94, and 0.57, respectively, for the discrimination between NAFLD and NL and 0.79 +/- 0.04, 0.70, and 0.81, respectively, for the discrimination between NASH and NAFL. When the analysis was performed excluding patients with glucose levels >136 mg/dL, the area under the receiver operating characteristic curve for the discrimination between NASH and NAFL increased to 0.81 +/- 0.04 with sensitivity and specificity of 0.73 and 0.80, respectively. Conclusion: The assessed noninvasive lipidomic serum tests distinguish between NAFLD and NL and between NASH and NAFL with high accuracy.Supported by the National Institutes of Health Blueprint for Neuroscience Research (R01AT001576 to S.C.L., J.M.M.), Agencia Estatal de Investigacion of the Ministerio de Economia, Industria y Competitividad (SAF2014-52097R to J.M.M.), CIBER Hepatic and Digestive Diseases and Instituto de Salud Carlos III (PIE14/0003 to J.M.M.), Etorgai 2015-Gobierno Vasco (ER-2015/00015 to R.M., I.M.A., C.A., A.C.), Plan de Promocion de la Innovacion 2015-Diputacion Foral de Bizkaia (6/12/IN/2015/00131 to A.C., C.A.), National Institute of Diabetes and Digestive and Kidney Diseases (RO1DK81410 to A.J.S.), and Czech Ministry of Health (RVO VFN64165 to L.V.)
