Elementary agriculture for city high schools

Approved, May 14, J.L. MeriamTypescriptM.A. University of Missouri 1913The experience of teaching Agriculture in the high school for a number of years has impressed upon the writer the need of a more careful selection of material than is indicated by most of the text book in Elementary Agriculture. From this broad and indefinite problem numerous problems arose. Wherein does agricultural subject-matter meet the needs of pupils? How do the needs of different pupils vary? How should the choice of subject-matter vary for different pupils? It appears that the needs of only those students who are to continue into college have been considered or that what is best to prepare for college is best to prepare for life. It is known that a very small percent of the pupils of the public school remains to graduate from the high school and a much smaller percent enters a high institution. It is being seriously questioned whether the training that prepares best for college prepares best for life if the student does not continue through to the college. It is not the purpose of this study to discuss the means of preventing withdrawals from school, but to suggest for high school students a line of work closely connected with the activities of life and yet not vocational in its purpose.Includes bibliographical reference

CamGrid: Experiences in constructing a university-wide, Condor-based grid at the University of Cambridge

Proceedings of the 2004 UK e-Science All Hands Meeting, 31st August - 3rd September, Nottingham UKIn this article we describe recent work done in building a university-wide grid at the University of Cambridge based on the Condor middleware [1]. Once the issues of stakeholder concerns (e.g. security policies) and technical problems (e.g. firewalls and private IP addresses) have been taken into account, a solution based on two separate Condor environments was decided on. The first of these is a single large pool administered centrally by the University Computing Service (UCS) and the second a federated service of flocked Condor pools belonging to various departments and run over a Virtual Private Network (VPN). We report on the current status of this ongoing work

On the computation of the maximal structured singular value for aeronautical applications

peer-reviewed                                                                                                                             This paper considers the necessary transformations and the computational issues associated with the determination of the maximal structured singular value without the use of a frequency gridding strategy. It is shown that, for the case of purely real model perturbations, convergence difficulties exist in determining bounds on the maximal structured singular value using existing Matlab software. A new computational scheme is presented which improves on existing methods for the computation of the worst case combination of real uncertain parameters. This scheme easily outperforms regularisation type solutions, which have been suggested as one way of improving the convergence properties of a strictly real robustness analysis. The improvement is illustrated on a well known civil aircraft robustness analysis example.    ACCEPTEDpeer-reviewe

Senior thesis, Kansas State Agricultural College, 1908.Introduction: Glanders is one of the most important infectious diseases of horses, asses and mules, and when transmitted to man one of the most fatal diseases of the human species.

Reconsidering the classification of sweet taste liker phenotypes: a methodological review

Human ingestive behavior depends on myriad factors, including both sensory and non-sensory determinants. Of the sensory determinants, sweet taste is a powerful stimulus and liking for sweetness is widely accepted as an innate human trait. However, the universality of sweet-liking has been challenged. Sub-groups exhibiting strong liking (sweet likers) or having aversive responses to sweet taste (sweet dislikers) have been described, but the methods defining these phenotypes are varied and inconsistent across studies. Here, we explore the strengths and weaknesses of different methodological approaches in identifying sweet taste liker phenotypes in a comprehensive review. Prior studies (N = 71) using aqueous sucrose solution-based taste tests and a definition of two or more distinct hedonic responses reported between 1970 and 2017 were summarized. Broadly speaking, four different phenotyping methods have been used: 1. Interpretation (visual or statistical) of the shape of hedonic response curves, 2. Highest preference using ratings, 3. Average liking above mid-point or Positive/Negative average liking method, and 4. Highest preference via paired comparisons. Key methodological weaknesses included the use of subjective or arbitrary criteria as well as adoption of protocols unsuitable for large-scale implementation. Overall, we did not identify a method distinctly superior to the others. Given the role of both hedonics and reward in food intake, a better understanding of individual variations in sweet taste perception could clarify how sweet-liking interplays with obesity or addictive behaviors such as alcohol misuse and abuse. The development of a universally used statistically robust and less time-consuming classification method is needed

Quantifying sweet taste liker phenotypes: time for some consistency in the classification criteria

Taste hedonics is a well-documented driver of food consumption. The role of sweetness in directing ingestive behavior is largely rooted in biology. One can then intuit that individual differences in sweet-liking may constitute an indicator of variations in the susceptibility to diet-related health outcomes. Despite half a century of research on sweet-liking, the best method to identify the distinct responses to sweet taste is still debated. To help resolve this issue, liking and intensity ratings for eight sucrose solutions ranging from 0 to 1 M were collected from 148 young adults (29% men). Hierarchical cluster analysis (HCA) revealed three response patterns: a sweet-liker (SL) phenotype characterized by a rise in liking as concentration increased, an inverted U-shaped phenotype with maximum liking at 0.25 M, and a sweet-disliker (SD) phenotype characterized by a decline in liking as a function of concentration. Based on sensitivity and specificity analyses, present data suggest the clearest discrimination between phenotypes is seen with 1.0 M sucrose, where a liking rating between −15 and +15 on a −50/+50 scale reliably distinguished individuals with an inverted U-shaped response from the SLs and the SDs. If the efficacy of this approach is confirmed in other populations, the discrimination criteria identified here can serve as the basis for a standard method for classifying sweet taste liker phenotypes in adults
