D.) University of Missouri-Columbia 2005.Dissertations, Academic -- University of Missouri--Columbia -- Agricultural education.Federal initiatives, state legislation, and educational leaders have encouraged educators to teach higher-order thinking skills. Teacher behaviors have been identified as variables of influence for higher-order thinking. The purpose of this study was to investigate the level of cognitive behavior exhibited by secondary agriculture teachers, how they compare to science teachers, and what characteristics are indicators of specific cognitive behaviors. The sample consisted of agriculture teachers in Central Missouri. Biology teachers from each school were utilized as a comparison group. For this descriptive-correlational study, the Florida Taxonomy of Cognitive Behaviors was used. Additionally, an attitudinal questionnaire was used to collect the teachers' attitude toward teaching at higher cognitive levels. Agriculture teachers had a slightly favorable attitude toward teaching at higher cognitive levels. Eighty-two percent of agriculture teachers' observed class time was spent on lower-order behavior. Science teachers were found to have similar results. No differences were found between agriculture and science teachers' cognitive behaviors. Measures should be taken at both the in-service and pre-service level to inform teachers of the importance of cognitive behavior and techniques for exhibiting cognitive behavior. Teacher, school, and class characteristics did not predict cognitive behavior with the current data

Drivers of farmers’ adoption of hermetic storage bags in Ghana

Post-harvest loss is a global challenge due to its serious threat to food security. Hermetic storage bags offer one way to combat the loss of food after harvest. The rate at which farmers adopt hermetic bags largely depends upon their access to information and training about the technology. The adoption of hermetic storage bags in Dormaa, Ghana, was the focus of this quantitative cross-sectional research study. This study sought to describe maize farmers’ perceptions of the hermetic storage bags in Dormaa, Ghana, based on the perceived innovation attributes and to ascertain farmers’ stages of adoption of the hermetic storage bags using Rogers’s (2003) innovation-decision model. A multistage systematic sampling technique was used to survey 217 maize farmers in four communities where maize production was the main economic activity. Data indicated that the largest group of farmers were at the confirmation stage of Rogers’ model. The logistic regression model was used to ascertain the influence of the innovation attributes on adoption. The findings reveal that of the five innovation characteristics, relative advantage, compatibility, and complexity are the key and significant drivers of the adoption of hermetic storage bags, with relative advantage and compatibility increasing the adoption likelihood and complexity reducing it. The study, therefore, recommends that communities lagging behind others in adoption should be targeted for additional training

Beyond the Post: Exploring Equine Operators’ Understanding and Role in Conservation Best Management Practices

The equine industry is an established part of Maryland agriculture with 79,100 equines valued at approximately $714 million in the state; approximately 10% of these animals are housed in one county. Equine operators are a unique demographic in the agricultural realm, because they are not managing land to produce food or fiber and often are employed in other professions unrelated to agriculture. These operators tend to be unaware of land conservation practices and can have a detrimental effect on areas, like the Chesapeake Bay economy and ecosystem, if shared resources are exploited. The purpose of this study was to explore equine operators’ knowledge and connection of conservation best management practices (BMPs) and their role in being a caretaker of the land. The study was informed by the diffusion of innovations theory and gathered data through semi-structured, qualitative interviews. Equine operators in the study were found to use a variety of informational sources, had a high level of adoption of the BMPs they used, and overall, a majority of participants saw their role as caretakers of the land as an important aspect of their environmental actions. Recommendations from this research include improving communication processes to increase the spread of BMPs and adjusting specific infrastructure aspects to improve retention of equine operators practicing conservation efforts. Further research should investigate other niche areas of agriculture that could potentially be struggling with a knowledge deficit of BMPs and communication neglect between conservation offices and audiences

Maize farmers’ use, preference, and trustworthiness of information sources and communication channels in Dormaa, Ghana: A gender comparison.

The study aimed to identify maize farmers\u27 use, preference, and trustworthiness of the various information sources and communication channels farmers in Dormaa, Ghana, used to receive information about their farming activities. A questionnaire was developed, and data was collected from 217 maize farmers. The result revealed more males are involved in maize production than females. Most males indicated they received training in using hermetic bags more than female farmers. Respondents ranked Extension agents highest as the source from which they receive their farming information. Based on the level of preference for the information sources, the results show a statistically significant difference between male and female farmers\u27 preference for Extension agents, friends/neighbors, and church leaders, with male farmers preferring these information sources more than females. The result indicated a significant difference between male and female preferences for phone calls, with more males indicating they preferred telephone calls. The t-test results of farmers’ trustworthiness for the information sources revealed a significant difference between male and female farmers’ trustworthiness for fellow farmers, friends/neighbors, telephone calls, and posters/billboards for communication channels. Given that Extension professionals are the most preferred and trustworthy source of information, we recommend that the government and stakeholders organize extension training programs to strengthen local extension. We recommend greater women involvement and given strategic roles in the planning and organization of training programs

In Their Own Words: Student Mental Health in Rural, Low Socioeconomic High Schools

The purpose of this research paper was to highlight the factors students and school staff identify as contributors to mental health issues students attending rural, low socioeconomic high schools experience and the specific mental health issues they witness most. A collective case study was conducted in four rural high schools, two in Kansas and two in West Virginia. Field work at each school involved observations, document collection, and semi-structured focus group interviews with students and school staff. The factors identified as contributors to poor student mental health were pressure, technology, home life, bullying, and stigma. Anxiety, stress, depression, lack of health coping, and suicidal comments emerged as the specific mental health struggles students deal with the most. Recommendations for practice include practical ways to address the identified contributors of poor student mental health in rural schools and strategies to normalize mental health in the rural school environment

Dark Matter Candidates: A Ten-Point Test

An extraordinarily rich zoo of non-baryonic Dark Matter candidates has been proposed over the last three decades. Here we present a 10-point test that a new particle has to pass, in order to be considered a viable DM candidate: I.) Does it match the appropriate relic density? II.) Is it {\it cold}? III.) Is it neutral? IV.) Is it consistent with BBN? V.) Does it leave stellar evolution unchanged? VI.) Is it compatible with constraints on self-interactions? VII.) Is it consistent with {\it direct} DM searches? VIII.) Is it compatible with gamma-ray constraints? IX.) Is it compatible with other astrophysical bounds? X.) Can it be probed experimentally?Comment: 29 pages, 12 figure

Polygenic Risk Scores for Prediction of Breast Cancer and Breast Cancer Subtypes

Stratification of women according to their risk of breast cancer based on polygenic risk scores (PRSs) could improve screening and prevention strategies. Our aim was to develop PRSs, optimized for prediction of estrogen receptor (ER)-specific disease, from the largest available genome-wide association dataset and to empirically validate the PRSs in prospective studies. The development dataset comprised 94,075 case subjects and 75,017 control subjects of European ancestry from 69 studies, divided into training and validation sets. Samples were genotyped using genome-wide arrays, and single-nucleotide polymorphisms (SNPs) were selected by stepwise regression or lasso penalized regression. The best performing PRSs were validated in an independent test set comprising 11,428 case subjects and 18,323 control subjects from 10 prospective studies and 190,040 women from UK Biobank (3,215 incident breast cancers). For the best PRSs (313 SNPs), the odds ratio for overall disease per 1 standard deviation in ten prospective studies was 1.61 (95%CI: 1.57-1.65) with area under receiver-operator curve (AUC) = 0.630 (95%CI: 0.628-0.651). The lifetime risk of overall breast cancer in the top centile of the PRSs was 32.6%. Compared with women in the middle quintile, those in the highest 1% of risk had 4.37- and 2.78-fold risks, and those in the lowest 1% of risk had 0.16- and 0.27-fold risks, of developing ER-positive and ER-negative disease, respectively. Goodness-of-fit tests indicated that this PRS was well calibrated and predicts disease risk accurately in the tails of the distribution. This PRS is a powerful and reliable predictor of breast cancer risk that may improve breast cancer prevention programs.NovartisEli Lilly and CompanyAstraZenecaAbbViePfizer UKCelgeneEisaiGenentechMerck Sharp and DohmeRocheCancer Research UKGovernment of CanadaArray BioPharmaGenome CanadaNational Institutes of HealthEuropean CommissionMinistère de l'Économie, de l’Innovation et des Exportations du QuébecSeventh Framework ProgrammeCanadian Institutes of Health Researc

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
