Novel monitoring systems to obtain dairy cattle phenotypes associated with sustainable production
Improvements in production efficiencies and profitability of products from cattle are of great interest to farmers. Furthermore, improvements in production efficiencies associated with feed utilization and fitness traits have also been shown to reduce the environmental impact of cattle systems, which is of great importance to society. The aim of this paper was to discuss selected novel monitoring systems to measure dairy cattle phenotypic traits that are considered to bring more sustainable production with increased productivity and reduced environmental impact through reduced greenhouse gas emissions. With resource constraints and high or fluctuating commodity prices the agricultural industry has seen a growing need by producers for efficiency savings (and innovation) to reduce waste and costs associated with production. New data obtained using fast, in some cases real-time, and affordable objective measures are becoming more readily available to aid farm level monitoring, awareness, and decision making. These objective measures may additionally provide an accurate and repeatable method for improving animal health and welfare, and phenotypes for selecting animals. Such new data sources include image analysis and further data-driven technologies (e.g., infrared spectra, gas analysis), which bring non-invasive methods to obtain animal phenotypes (e.g., enteric methane, feed utilization, health, fertility, and behavioral traits) on commercial farms; this information may have been costly or not possible to obtain previously. Productivity and efficiency gains often move largely in parallel and thus bringing more sustainable systems
Pleural fluid soluble triggering receptor expressed on myeloid cells-1 as a marker of bacterial infection: a meta-analysis
<p>Abstract</p> <p>Background</p> <p>Pleural infection is a common clinical problem. Its successful treatment depends on rapid diagnosis and early initiation of antibiotics. The measurement of soluble triggering receptor expressed in myeloid cells-1 (sTREM-1) level in pleural effusions has proven to be a valuable diagnostic tool for differentiating bacterial effusions from effusions of other etiologies. Herein, we performed a meta-analysis to assess the accuracy of pleural fluid sTREM-1 in the diagnosis of bacterial infection.</p> <p>Methods</p> <p>We searched Web of Knowledge and Medline from 1990 through March 2011 for studies reporting diagnostic accuracy data regarding the use of sTREM-1 in the diagnosis of bacterial pleural effusions. Pooled sensitivity and specificity and summary measures of accuracy and Q* were calculated.</p> <p>Results</p> <p>Overall, the sensitivity of sTREM-1was 78% (95% CI: 72%-83%); the specificity was 84% (95% CI: 80%-87%); the positive likelihood ratio was 6.0 (95% CI: 3.3-10.7); and the negative likelihood ratio was 0.22 (95% CI: 0.12-0.40). The area under the SROC curve for sTREM-1 was 0.92. Statistical heterogeneity and inconsistency were found for sensitivity (p = 0.015, χ<sup>2 </sup>= 15.73, I<sup>2 </sup>= 61.9%), specificity (p = 0.000, χ<sup>2 </sup>= 29.90, I<sup>2 </sup>= 79.9%), positive likelihood ratio (p = 0.000, χ<sup>2 </sup>= 33.09, I<sup>2 </sup>= 81.9%), negative likelihood ratio (p = 0.008, χ<sup>2 </sup>= 17.25, I<sup>2 </sup>= 65.2%), and diagnostic odds ratio (p = 0.000, χ<sup>2 </sup>= 28.49, I<sup>2 </sup>= 78.9%). A meta-regression analysis performed showed that the Quality Assessment of Diagnostic Accuracy Studies score (p = 0.3245; RDOR, 4.34; 95% CI, 0.11 to 164.01), the Standards for Reporting of Diagnostic Accuracy score (p = 0.3331; RDOR, 1.70; 95% CI, 0.44 to 6.52), lack of blinding (p = 0.7439; RDOR, 0.60; 95% CI, 0.01 to 33.80), and whether the studies were prospective or retrospective studies (p = 0.2068; RDOR, 7.44; 95% CI, 0.18 to 301.17) did not affect the test accuracy. A funnel plot for publication bias suggested a remarkable trend of publication bias.</p> <p>Conclusions</p> <p>Our findings suggest that sTREM-1 has a good diagnostic accuracy and may provide a useful adjunctive tool for the diagnosis of bacterial pleural effusions. However, further studies are needed in order to identify any differences in the diagnostic performance of sTREM-1 of parapneumonic effusions and empyemas.</p
Peddling a semiotics of fear: a critical examination of scare tactics and commercial strategies in public health promotion
This study critically examines the ways in which the nationwide Diabetes UK/Tesco public health promotion campaign (2013-2014) sought to raise awareness of Type 2 diabetes. Conducting a multimodal critical discourse analysis of six campaign images, we identify the presence of fear-inducing, stigmatising and commercial strategies, through which the campaign emphasises the dangers of diabetes and advocates personal responsibility for assessing both individual and others’ risk of the disease. Specifically, three discursive techniques are deployed in this campaign to achieve these ends: (1) the depiction of grief and amplification of diabetes-related danger, (2) the promotion of diabetes risk and responsibilization of individuals for their health, and (3) the commercial branding and framing of the Diabetes UK/Tesco partnership as providing tools for diabetes prevention and management. Our findings raise concerns about the moral legitimacy of using fear-inducing and commercial strategies in public health campaigns, strategies which do little to address the environmental factors which are associated with increasing rates of the disease
UK bioenergy innovation priorities: Making expectations credible in state-industry arenas
AbstractThe UK government has promoted bioenergy for several policy aims. Future expectations for bioenergy innovation encompass various pathways and their potential benefits. Some pathways have been relatively favoured by specific state-industry arrangements, which serve as ‘arenas of expectations’. Through these arrangements, some expectations have been made more credible, thus justifying and directing resource allocation. Conversely, to incentivise private-sector investment, government has sought credibility for its commitment to bioenergy innovation. These dual efforts illustrate the reciprocal character of promise-requirement cycles, whereby promises are turned into requirements for state sponsors as well as for innovators.Collective expectations have been shaped by close exchanges between state bodies, industry and experts. As promoters build collective expectations, their credibility has been linked with UK economic and environmental aims. When encountering technical difficulties or delays in earlier expectations, pathways and their benefits have been broadened, especially through new arenas—as grounds to allocate considerable state investment. Thus the concept ‘arenas of expectations’ helps to explain how some pathways gain favour as innovation priorities
Estimated differences in economic and environmental performance of forage-based dairy herds across the UK
Differences in performance among the areas of England, Scotland, Wales and Northern Ireland can provide some insight into the resilience of UK milk supplies from forage-based dairy herds. This study used a Markov Chain approach to model the average herd in each region between the years 2010 to 2015. The effect of a single unit change in milk production (milk volume, fat yield and protein yield), fitness (survival, somatic cell count, mastitis and calving interval) and efficiency (methane) traits on the economic value and GHG emissions intensity (expressed as carbon dioxide equivalents per cow and per kg milk solids) were assessed. Production data were obtained from a total of about half a million milk recorded dairy cows in the UK and the Farm Business Surveys for each region. Across the UK improving the health (SCC and mastitis), fertility (calving intervals) and survival of cows will increase profitability and reduce emissions intensity of milk production. In Scotland, herds had higher milk yields but poorer survival, which potentially could be due to poor fertility indicated by a longer calving interval compared to other regions. Herds in Northern Ireland had the shortest average calving interval but the highest somatic cell counts (SCC), and thus greater estimated mastitis incidence and wasted milk. Notably, England had considerably higher economic values (between 10 and 30%) and emission intensity values (between 11 and 37%) for SCC and mastitis incidence than other regions, due to lost milk production and the higher gross margin. This study provides a framework that can be customised for individual herds to allow assessment of resilience and resource efficiency of milk production not only in the UK but for comparison with international dairy systems

On the organisation of round robin tournaments with constraints
A sporting league places every team into one of several divisions of equal size, and runs a round robin tournament for each division. Some teams are paired with another team, not necessarily in the same division, to share facilities. It is shown that however many teams are paired and whatever the pairings, it is always possible to schedule the fixtures in the minimum time, so that no two paired teams have home matches simultaneously.
