The celebrated Sherpas of Himalayan mountaineering, who lived in the rugged high-altitude environment of the Everest area of Nepal, lacked Western style medical services and so iconic New Zealander, Sir Edmund Hillary, 'hero' of Everest, built them a small hospital in 1966. He administered Khunde Hospital through the Himalayan Trust, but with substantial support, since the late-1970s, from the Sir Edmund Hillary Foundation in Canada. Overseas medical volunteers assisted by local staff provided a range of outpatient and inpatient, curative and preventive services. The history of Khunde Hospital, therefore, provides a case study for the introduction of modern medicine, as Sherpas referred to Western or biomedicine, and for the implementation of an overseas aid project. In my analysis I have moved away from a binary, oppositional examination of a cross-cultural encounter and have situated Khunde Hospital in a conceptual device of 'worlds'. I argue that the hospital existed and operated simultaneously within multiple separate yet interconnected worlds, but do not privilege one discourse over another. These worlds work beyond culture, encompassing institutions, political structures and knowledge communities and were physical, social and intellectual spaces within which there were rules and norms of behaviour that structured action. In order to explore the histories of Khunde Hospital I set it within four distinct but overlapping worlds: that of Sir Edmund Hillary, the Sherpa, Western medicine and international aid. These are worlds that I have identified as being important for the questions I am looking at. My central discussion is the ongoing encounter between Sherpa beliefs and practices about sickness and modern medicine, particularly looking at the individual patient�s use and non-use of the hospital and how staff there responded. The response was neither a one-way diffusion of Western medical practice, nor a collision between the spirit-suffused system of the Sherpa and scientific biomedicine. People used the hospital for some things but not others, based on their perception as to whether the hospital was the effective, appropriate option to take. Over the years, the hospital and community became used to each other in a relationship that was in practice a coexistence of difference. Each acknowledged and could incorporate aspects of the other�s beliefs and practices when dealing with a person�s sickness, but remained separate. Using the conceptual device of worlds, however, suggests the need for this example of the introduction and spread of Western medicine to be grounded in a consideration of Hillary�s particular form of aid, the shifting discourse of international medical aid between the 1960s and the 1990s and the unique world of the Sherpa of Khumbu. All of these worlds influenced the provision of health care at and from Khunde Hospital in different ways, sometimes separately but often simultaneously, and at some times and for some issues more than others. People, place and relationships often had as much influence as - and sometimes more than - the medicine. If the key to understanding Khunde Hospital is the relationship between Sherpas and Hillary and the respect that began in a partnership on the mountains in the 1950s, then the multiple worlds of Khunde Hospital underscore the complexities of implementing Sherpa requests to build a hospital in their rugged home near the world�s highest mountain.

The insect society living in oilseed rape is large. Change of the crop characteristics affects both harmful species and beneficious ones. The latter group consists of a lot of members of order Hymenoptera. This work focuses on the evaluation of impact of white oilseed rape cultivation on the insect society in comparison with two yellow winter varieties. Newly bred winter oilseed rape line variety Witt was compared to two hybrid varieties of yellow rape; Sherpa and DK Sensei. The experiment was carried out in 2015 and its plots were placed at Ruzyně at Crop Reserach Institute (VÚRV, v. v. i.) and also at the Experimental Unit of Czech University of Life Sciences (ČZU) in Uhříněves. The insects were collected by sweeping net, soil larvae traps and soil emergence traps. The occurrence of serious pests (pollen beetle Brassicogethes aeneus, brassica pod midge Dasineura brassicae, cabbage seed weevil Ceutorhynchus obstrictus, stem flea beetle Psylliodes chrysocephalus and cabbage flea beetles Phyllotreta sp.) was recorded. Dominant parasitoid species were Tersilochus heterocerus, Platygaster subuliformis, Trichomalus perfectus, Mesopolobus morys and Omphale clypealis. The level of pest mortality was evaluated. Numbers of species identified by key were processed using generalized linear model method in R statistical software. The results confirm suitability of the assessed varieties in the white oilseed rape cultivation system, notably in the combination of Sherpa and Witt. They give an insight into parasitoid community of oilseed rape in Czech republic, which is useful for management of serious pest species.

The Trivers-Willard hypothesis predicts a sex ratio bias contingent on maternal condition in species characterized by variation in male reproductive success. A male-biased sex ratio among mothers in good condition, and a female-biased sex ratio among mothers in poor condition is expected. Studies in humans have thus far provided mixed answers to the question of whether or not sex ratio is affected by maternal condition. The present study assessed whether or not the introduction of a western cash economy influenced the observed secondary sex ratio in Nepal's Khumbu region. Because acculturated villages provided better access to the cash economy and to health facilities, residence in an acculturated village was used as a proxy for "good" maternal condition. I analyzed demographic data gathered by survey in 1971 and 1982. The sample included 734 children from the 1971 survey and 1598 children from the 1982 survey. Using Poisson regression I analyzed the extent to which the sex ratios in age-stratified groups differed between the acculturated and unacculturated villages. In the 1971 dataset, the younger women in the acculturated villages displayed a significantly higher (p=.014) proportion of male offspring. It is likely that older women were subjected to minimal acculturation effects during their child-bearing years and among these data there was a lack of significant deviation between acculturated and unacculturated post-menopausal women. The rapid overall increase in acculturation between 1971 and 1982 likely made conditions in the two sets of villages much more similar by 1982. The results of this study underscore the impact that the transition to a market economy had on women in Nepal's Khumbu region. / Anthropology

With the constantly increasing precision of experimental data acquired at the current collider experiments Tevatron and LHC the theoretical uncertainty on the prediction of multiparticle final states has to decrease accordingly in order to have meaningful tests of the underlying theories such as the Standard Model. A pure leading order calculation, defined in the perturbative expansion of said theory in the interaction constant, represents the classical limit to such a quantum field theory and was already found to be insufficient at past collider experiments, e.g. LEP or Hera. Such a leading order calculation can be systematically improved in various limits. If the typical scales of a process are large and the respective coupling constants are small, the inclusion of fixed-order higher-order corrections then yields quickly converging predictions with much reduced uncertainties. In certain regions of the phase space, still well within the perturbative regime of the underlying theory, a clear hierarchy of the inherent scales, however, leads to large logarithms occurring at every order in perturbation theory. In many cases these logarithms are universal and can be resummed to all orders leading to precise predictions in these limits. Multiparticle final states now exhibit both small and large scales, necessitating a description using both resummed and fixed-order results. This thesis presents the consistent combination of two such resummation schemes with fixed-order results. The main objective therefor is to identify and properly treat terms that are present in both formulations in a process and observable independent manner. In the first part the resummation scheme introduced by Yennie, Frautschi and Suura (YFS), resumming large logarithms associated with the emission of soft photons in massive Qed, is combined with fixed-order next-to-leading matrix elements. The implementation of a universal algorithm is detailed and results are studied for various precision observables in e.g. Drell-Yan production or semileptonic B meson decays. The results obtained for radiative tau and muon decays are also compared to experimental data. In the second part the resummation scheme introduced by Dokshitzer, Gribov, Lipatov, Altarelli and Parisi (DGLAP), resumming large logarithms associated with the emission of collinear partons applicable to both Qcd and Qed, is combined with fixed-order next-to-leading matrix elements. While the focus rests on its application to Qcd corrections, this combination is discussed in detail and the implementation is presented. The resulting predictions are evaluated and compared to experimental data for a multitude of processes in four different collider environments. This formulation has been further extended to accommodate real emission corrections to beyond next-to-leading order radiation otherwise described only by the DGLAP resummation. Its results are also carefully evaluated and compared to a wide range of experimental data.

East Tennessee State University developed a workflow to add journal publications to their institutional repository and faculty profiles using three tools: Zotero for entering metadata, SHERPA/RoMEO for checking copyright permissions, and Unpaywall for locating full-text documents. This study evaluates availability and accuracy of the information and documents provided by Zotero, SHERPA/RoMEO, and Unpaywall for journal publications in four disciplines. The tools were less successful with works authored by arts and humanities and education faculty in comparison to works authored by medicine and health sciences and social and behavioral sciences faculty. The findings suggest that publisher practices contributed to the disciplinary differences.

Several analytical techniques including use case diagrams, process flow diagrams (PFDs), hierarchical task analysis (HTA), failure mode and effects analysis (FMEA), systematic human error reduction and prediction approach (SHERPA), hazard analysis and critical control point (HACCP), heuristics, the Safe Living Guide and the Resident Assessment Instrument – Home Care (RAI-HC) are applied to data obtained from two pilot home visits to determine whether common failure modes, causes, effects and recommendations are yielded by the techniques. The time required to apply each analytical technique to processes uncovered from the pilot data was measured and outputs of the techniques were reviewed for commonality. Of the tools considered, SHERPA was found to return the most failure modes, effects and recommendations, while FMEA was the only human factors tool to yield causes. Additionally, FMEA and SHERPA provided a means of ranking potential failure modes based on severity and probability.

The number of prehospital deaths caused by large bleedings could be decreased if civilian people would act in time to help the injured patient. One way to help is to stop the bleeding with a tourniquet application. However, the tourniquet needs to be placed correctly in order to stop the bleeding. Therefore laypersons need to be educated in bleeding control to increase the rate of successful tourniquet application. This study used human error identification techniques such as Hierarchical Task Analysis and Systematic Human Error Reduction and Prediction Approach to identify possible errors of four commonly used tourniquet models: the CAT-7, Delfi-EMT, SAM-X and SWAT-T. The results show that many predicted errors are time-oriented and critical. Video analysis of tourniquet application was performed to map occurred use errors from the videos with the predicted ones. The goal was to identify problems that could be solved by training or redesigns of the tourniquets. The results show that the most common errors for all participants during tourniquet application were of six error types. The errors were to not check time or write down time of application, to take too much time to place the tourniquet around the limb, to place the tourniquet upside down, to place the tourniquet band over the securing mechanism instead of between and lastly to not secure the tourniquet correctly before transporting the patient. The untrained laypersons made more errors than the trained laypersons and professional emergency personnel group. The trained laypersons also made fewer errors in a calm setting than in a stressed setting, comparing to the professional group who did the same error types in both settings. The results indicate that untrained laypersons not only make more errors but also more critical errors than trained laypersons and professional emergency personnel. Future research should empirically test other tourniquet models than the CAT in the goal of finding use errors to be reduced. Overall the results are in line with previous studies that show the need for education of bleeding control techniques in the civilian population.
