Examining Phenotypic Structural Traits as Indicators for Reproductive Longevity Success in Sows

The objective of this study was to examine structure and body conformation traits of 494 gilts/sows as a prediction of reproductive longevity in sows. This study focused on specific traits including body length, body depth, front and rear pastern angles, knee angle, and hock angle. The primary method of data collection was based on videos. Still images were pulled from the videos when the sow was standing in a natural stance. The images were analyzed and interpreted objectively with Image J which gives the availability to measure distance and angles given known references in the images. The structural data was analyzed for association with reproductive efficiency including feed intake, wean to estrus interval, weight loss, number born alive, and number of parities achieved. The angle measurements on young sows are not as consistent as older, calmer sows. Front pastern angle was significantly associated with P1 Success at 112 days of age. This trait is critical to early survival before any animals are culled. Angles showed significance or trended toward significance predominately at the early first gestation timepoint. Height at flank at all timepoints is significantly associated with LTNP. Smaller animals have a greater success reaching parity 4 and significant advantages in lifetime reproduction traits compared to the larger animals. As producers are making selections on their replacement gilts, they should avoid selecting the largest females

Test-retest; The reliability of the DEM, King-Devick, and Visagraph

The Developmental Eye Movement Test (DEM), King-Devick (K-D), and Visagraph are three of the most frequently employed tests currently being utilized to assess eye movements in Optometric practice today. Although these tests have been normed, there have been no studies that assess the test-retest reliability and correlations between these most commonly used eye movement tests. Thirty-four elementary school children, between the ages of 9 and 11, were screened for visual abnormalities: Three trials for each test were presented in random order, with one week intervals between tests 1 and 2, and 2 and 3. The DEM showed significant differences between trials 1 and 2, and 1 and 3. K-D showed significant differences for subtest III between trials 1 and 3, and Visagraph showed significant differences between trials 1 and 3 for rate without rereading. A high correlation (R=.841) between DEM and K-D was also found. Correlations between Visagraph and DEM and Visagraph and KD were not quite as high, but still good (R=.500), (R=.506) respectively. These results indicate a change in performance, possibly due to test familiarity existing. Single administration of these tests may not be adequate with pretesting strongly recommended. High correlations between the DEM and K-D may preclude the need for performing both tests

Segment reporting and trade unions in South Africa.

Thesis (M.Acc.)-University of Natal, 1997.During the early 1970's two trends emerged in the South African business environment. The first trend was that the number of diversified enterprises started increasing, and the second trend was that there was a steady increase in the activities and power of trade unions. These two trends were considered during the evaluation of prior research on the topic of segment reporting. Prior research on segment reporting focused on the usefulness of segment reporting, the problems associated with segment identification, the objections to providing segment information, and the extent to which diversified companies disclose segment information. Using the trends identified and the prior research, the research problem developed was as follows: are the segment disclosures of South African listed companies sufficient to meet the information needs of trade unions in South Africa, and if not, what additional information do trade unions require? The research problem was limited to listed companies as it was identified that trade unions may experience difficulty in obtaining information which is not available to the general public. In addressing the problem, the following three objectives were formulated: (i) to determine if trade unions use segment information, (ii) to determine what their requirements are in respect of segment information, and (iii) if trade unions do not use segment information, to determine why segment information is not used. In order to achieve these three objectives, it was necessary to conduct a survey of trade unions on their use of segment information. This survey was undertaken as a series of replicative case studies with the primary data being obtained by means of interviews. Generalisations were then made about the use that trade unions make of segment information. The main conclusions to this research were: (i) trade unions use segment information unless they are part of a national bargaining forum, (ii) trade unions consider segment information to be at least as useful as consolidated information, and (iii) trade unions use segment information primarily to form the basis for wage negotiations and to assess overall company performance. Once these conclusions had been drawn, the results were compared to results of a survey of investment analysts in South Africa, and evaluated against proposals contained in the International Exposure Draft (E51) on segment reporting. There were similarities between the segment itnformation needs of trade unions and investment analysts, although the trade unions required more information regarding employees and the remuneration of management. Trade unions also indicated that the proposals contained in the exposure draft would be acceptable, although the unions would require more employee information on a segment basis to be disclosed. Thus, the research project achieved its objectives. In addition, areas for further research within the area of segment reporting were identified

The appeal of the Functional Fitness MOT to older adults and health professionals in an outpatient setting: a mixed-method feasibility study

Purpose: To understand the views and perceptions regarding the Functional Fitness MOT (FFMOT), a battery of functional tests followed by a brief motivational interview, of both the older people undergoing it and the health professionals delivering it. Patients and methods: Physically inactive older adults (n=29) underwent the FFMOT and subsequently attended focus groups to share their perceptions of it and to discuss the barriers, motivators, health behavior change, and scope to improve physical activity (PA) levels. PA levels were recorded at baseline and again at 12 weeks together with a post-intervention questionnaire concerning behavior change. Participating physiotherapists and technical instructors were interviewed. Results: Most participants felt they had learned about their abilities and comparisons with their peers, had a change in perception about the importance of good balance and strength, and felt the FFMOT helped raise their awareness of local and self-directed physical activity opportunities. Most felt their awareness of the need for PA had not changed, but 25% of participants started a new organized PA opportunity. The health professionals perceived the FFMOT as being easy to administer, educating, and motivating for participants to increase their PA. Space, time, finances, and insecurity about having the necessary skills to conduct the FFMOTs were seen as barriers in implementing the FFMOT in daily practice. Conclusion: Over half of those offered the FFMOT accepted it, suggesting it is appealing. However, most participants felt they were already active enough and that their awareness of the need for PA had not changed. There were positive perceptions of the FFMOT from both professionals and older people, but both felt the FFMOT could be held in a community venue. The overall findings suggest that the FFMOT is feasible in the clinical setting, but its effectiveness has yet to be determined

User experience and clinical effectiveness with two wearable global positioning system devices in home dementia care

Introduction: The user experience and clinical effectiveness with wearable global positioning system (GPS) devices for persons with dementia (PwDs) and caregivers (CGs) remain unclear although many are available. Methods: Using a crossover design, 20 dyads tested two similar commercial GPS watches (products A and B) at home for 4 weeks each. Usability, product functions, design features and product satisfaction at home and the clinic were investigated. Caregiver burden and quality of life assessed clinical effectiveness. Results: The final 17 dyads rated the usability, telephone function, overall design features, font, buttons, and battery life of B significantly better than A. PwDs rated the overall design features and buttons of A significantly better than CGs. Product satisfaction with both products was significantly lower at home. Clinical effectiveness was not found. Discussion: User experience can be improved by optimizing specific product details. This might translate to clinical effectiveness. Social desirability bias may explain different product satisfaction ratings

Tactical Themes for Rangeland Research

The problems threatening the conservation and management of rangeland, over one-half of the world’s terrestrial surfaces, are significant and growing. Current assessments of drivers and externalities shaping these problems have resulted in strategies intended to result in sustainable development of these lands and their resources. However, how can individual scientists and individual research programs support the needed strategies and goals? What can we realistically contribute and accomplish? We believe that technology can connect individual scientists and their science to the problems manifest in rangelands over the world, in a more rapid exchange than has occurred in the past. Recognition of local challenges, innovations, and scientific tests of the effectiveness of our technological solutions to these problems can keep pace with rapid change and help us adapt to that change. However, to do this, we have to invest in a process of connecting science to landscapes. Our tactics are to link, openly and collaboratively, the scientific method to discrete, specific, managed landscapes. We term these collective tactics, our fundamental research theme, “Landscape Portals”. All of the elements of this theme exist currently, to various degrees, but they lack cohesion and interactive, real-time connections. Future investment requires two basic, tactical scientific behaviors: a post-normal application of science in support of land management by hypothesis and a scientific method modified to accommodate a data intensive scientific inquiry directed towards adaptive management. These behaviors support our “Landscape Portals” theme: science conducted in a highly interactive, transparent, data enriched, locally relevant, globally connected, popularly translated, and ecologically robust manner

Transportation Energy Pathways LDRD.

This report presents a system dynamics based model of the supply-demand interactions between the USlight-duty vehicle (LDV) fleet, its fuels, and the corresponding primary energy sources through the year2050. An important capability of our model is the ability to conduct parametric analyses. Others have reliedupon scenario-based analysis, where one discrete set of values is assigned to the input variables and used togenerate one possible realization of the future. While these scenarios can be illustrative of dominant trendsand tradeoffs under certain circumstances, changes in input values or assumptions can have a significantimpact on results, especially when output metrics are associated with projections far into the future. Thistype of uncertainty can be addressed by using a parametric study to examine a range of values for the inputvariables, offering a richer source of data to an analyst.The parametric analysis featured here focuses on a trade space exploration, with emphasis on factors thatinfluence the adoption rates of electric vehicles (EVs), the reduction of GHG emissions, and the reduction ofpetroleum consumption within the US LDV fleet. The underlying model emphasizes competition between13 different types of powertrains, including conventional internal combustion engine (ICE) vehicles, flex-fuel vehicles (FFVs), conventional hybrids(HEVs), plug-in hybrids (PHEVs), and battery electric vehicles(BEVs).We find that many factors contribute to the adoption rates of EVs. These include the pace of technologicaldevelopment for the electric powertrain, battery performance, as well as the efficiency improvements inconventional vehicles. Policy initiatives can also have a dramatic impact on the degree of EV adoption. Theconsumer effective payback period, in particular, can significantly increase the market penetration rates ifextended towards the vehicle lifetime.Widespread EV adoption can have noticeable impact on petroleum consumption and greenhouse gas(GHG) emission by the LDV fleet. However, EVs alone cannot drive compliance with the most aggressiveGHG emission reduction targets, even as the current electricity source mix shifts away from coal and towardsnatural gas. Since ICEs will comprise the majority of the LDV fleet for up to forty years, conventional vehicleefficiency improvements have the greatest potential for reductions in LDV GHG emissions over this time.These findings seem robust even if global oil prices rise to two to three times current projections. Thus,investment in improving the internal combustion engine might be the cheapest, lowest risk avenue towardsmeeting ambitious GHG emission and petroleum consumption reduction targets out to 2050.3 AcknowledgmentThe authors would like to thank Dr. Andrew Lutz, Dr. Benjamin Wu, Prof. Joan Ogden and Dr. ChristopherYang for their suggestions over the course of this project.
