Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals (132 swamp buffaloes and 98 river buffaloes) sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production. 相似文献

Reflecting through the Indian experiences, a brief attempt is made to explore how disability as a noun takes shape in popular common sense “call names” (adjectives) and how does the popular common sense legitimise and normalise the oppressive language and the oppressed reality of the persons with disabilities? In the Indian context, the contempt for persons with disabilities is writ large in the language used to address them. However, to be conscious of this contempt, one needs to be conscious of the hegemonic nature of the popular common sense which normalises an oppressive reality as a natural social reality. The discussion on disability and popular common sense in India through the framework of “noun vs. adjective” might be helpful in gauging the challenges to the disability rights movement and the socio-cultural specificities to be reckon with for any meaningful intervention in the field of disability. 相似文献

Homeowner insurance rate making is an important public policy issue in the State of Florida. The State of Florida has over 2 trillion dollars of residential properties exposed to hurricane risk. The State has declared that it shall adopt public policy to encourage the use of sophisticated actuarial methods to assure that consumers are charged lawful insurance rates (Section 627.0628(1)(a)). To that effect, the State's insurance regulatory agency, the Florida Office of Insurance Regulation (OIR), sponsored the development of a Florida Public Hurricane Loss Model (FPHLM) to assess the risk and project insured residential losses. The FPHLM is an open and public model that has been developed primarily by university experts without influence from either the insurance industry or the state regulators. It is open to public scrutiny and provides an understandable baseline to check the assumptions as well as the outputs of the proprietary models. The FPHLM thus makes the rate evaluation process more objective and less political. It enables the state to justify rejecting or accepting rate increases based on an independent and transparent model, rather than a process that can be influenced politically. As a multi-disciplinary large scale research project with an iterative and incremental development cycle, the FPHLM system development and integration faced numerous challenges varying from technical factors to project management aspects. This paper will discuss the research experiences accumulated during the development of the FPHLM and the impact it has had on the homeowner insurance rate filing process in the State of Florida. 相似文献

Abstract Customer orientation has been suggested to create competitive advantage of firms (Kohli &; Jaworski, 1990). Therefore, the recommendation to media managers has been to let the creation and delivery of customer value guide their strategies for advertising sales (Aris &; Bughin, 2005). However, the concept of customer value, what it is, and how it is created remains unclear in many ways. This article explores the concept of customer value in advertising media purchasing from the media seller's perspective. Between December 2007 and February 2008, sales representatives from three Swedish TV networks were studied through in-depth interviews and observations as they progressed through a negotiation process with a large advertiser and its media agency. A qualitative analysis of the media sellers' experiences shows that they see advertiser and agency to perceiving the value of advertising media differently. Also, they see the customer side parties as diverging in the processes by which these value perceptions are formed. The article reveals the inherent problem of customer orientation on advertising markets—that within media purchasing practice, several actors have their own idea of value, and an advertiser's understanding of value is not always a decisive factor. The TV networks in the study have all chosen different strategies to deal with these dualities. 相似文献

External written examinations are commonly used for determining student academic achievement. The influence of question type and cognitive process on examination performance in senior-secondary physical education is unclear. A secondary data analysis of Victorian Certificate of Education (VCE) Physical Education examination data (2011; n?=?9,323, 2012; n?=?8,781) was conducted. Question type (multiple choice and short answer) and overall examination performance were compared and the predictive value of question type, cognitive process (based on Bloom’s revised taxonomy), and overall examination scores determined. In 2011 and 2012, students performed significantly better on multiple-choice questions; however, short-answer performance better predicted overall exam performance. A significant difference between marks achieved by cognitive level and grade (Ungraded [UG] – A+) was found. Low-achieving students (UG – D) were performing well below the examination mean across all questions. Developing higher order thinking skills for all students may lead to improved overall examination performance in VCE Physical Education. 相似文献

Background: Senior secondary physical education courses for certification continue to evolve with curricula reform occurring to ensure content is contemporary, student learning outcomes are maximised and assessment practices are valid for determining certification of students. The content of examinable senior secondary physical education courses privilege theoretical concepts over student physical performance of motor skills and this is reflected in the use of written assessment of cognitive outcomes in many courses internationally.Purpose: Student examination data were analysed from the year 12 (exit year) written examination of Victorian Certificate of Education (VCE) Physical Education to determine if student performance varied by Area of Study (content). Additionally, it investigated whether there was a relationship between student performance in each of the four Areas of Study examined and overall examination performance and considered the alignment of curriculum, assessment and pedagogy and the implications the findings may have on the teaching of VCE Physical Education in the future.Methods: A secondary data analysis of student results from the 2011 (n?=?9323; M?=?5212, F?=?4111) and 2012 (n?=?8781; M?=?5011, F?=?3770) VCE Physical Education (Victoria, Australia) examinations were conducted. Examination questions were categorised by content, and means and standard deviations (SD) for discrete and continuous data were calculated, and categorical variables were presented as percentages. Regression analysis was also performed to establish the relationship between student cohort size and examination scores. An independent sample t-test was used to explore the examination scores and each Area of Study scores across 2011 and 2012. A one-way ANOVA were performed to investigate the differences of each Area of Study scores between examination grades from UG to A+.Results: The results showed a positive correlation between VCE Physical Education student cohort size in a school and examination score in 2011 and 2012. Student performance differed across both years (2011 and 2012) and across Areas of Study within each of the years analysed. Students performed significantly lower on questions relating to the ‘planning, implementing and evaluating a training program’ Area of Study in 8 of the 11 possible grades (2011) and 10 of the possible 11 grades (2012) than in each of the other Areas of Study.Discussion and conclusions: This study reveals that student performance on the external VCE Physical Education examination is not consistent across all content areas (Areas of Study). This may suggest that student difficulties in answering questions based on content in ‘planning, implementing and evaluating a training program’ result from topic or content difficulty rather than process or question difficulty. From these findings, implications for teaching examinable physical education effectively include the use of experiential learning and practical experiences to provide students with experiences from which they can draw knowledge when completing written assessment tasks. Additionally, the importance of having the required content knowledge to teach examinable physical education confidently for pre-service and in-service teachers is discussed. 相似文献

Multiple individual and neighbourhood characteristics are theorised to influence adult sedentary behaviour. The aim of this study was to examine associations between individual and neighbourhood-level characteristics in 40 deprived neighbourhoods in London, UK. A cross-sectional design was utilised with baseline data from the Well London Cluster Randomised Controlled Trial in 40 deprived neighbourhoods in London. Multilevel linear regression was used to examine associations between individual characteristics (measured by household survey), neighbourhood characteristics (neighbourhood audit, GIS and routinely available datasets) and sedentary behaviour (sitting time). Individual-level positive mental well-being and health behaviours were associated with sedentary time. Individual-level social networks were associated with decreased sedentary time in men and increased sedentary time in women. Neighbourhood-level measures of social networks and perceived neighbourhood quality were associated with reduced sedentary time. Fifteen per cent of the variance in sedentary time was attributable to differences at the neighbourhood level (intra-class correlation coefficient?=?0.15). These findings suggest that social networks at the individual and neighbourhood levels, collective perceptions of neighbourhood quality, individual-level positive mental well-being and other health behaviours may be important components of interventions developed to reduce sedentary time in deprived populations. 相似文献

Wild cotton species can contribute a valuable gene pool for agronomically desirable cultivated tetraploid cultivars. In order to exploit diploid cotton a regeneration system is required to achieve transformation based goals. The present studies aimed at optimizing the conditions for regeneration of local varieties as well as wild species of cotton. Different callus induction media were tested with varying concentrations of hormones in which sucrose was used as nutritional source. Different explants （hypocotyls, cotyledon, root） were used to check the regeneration of both local cotton plants and wild relatives using T ＆ G medium, BAP medium, CIM medium, EMMS medium, and cell suspension medium. Different stages of embryogenicity such as early torpedo stage, late torpedo stage, heart stage, globular stage and cotyledonary stage were observed in wild relatives of cotton. The results of this study pave the way for establishing future transformation methods. 相似文献
