<p>Chapter 1: Currently there is no hunting or trapping season on bobcats in Indiana. While a season is being considered by wildlife administrators, there is no basis for establishing a price or understanding potential demand for this species. We use contingent valuation to estimate furbearer hunter and trapper willingness-to-pay (WTP) for a hypothetical bobcat harvest permit in Indiana, USA. Using a mail survey of 2000 randomly selected Indiana registered hunters and trappers, we presented respondents with a description of a hypothetical harvest season, including season dates, equipment restrictions, check-in procedures, counties open for the legal harvest, bag limit (the number of animals that can be legally harvested per individual), and statewide quota (the number of animals that can be legally harvested in aggregate). Following the description, respondents were asked a single-bounded dichotomous choice question about purchasing the proposed permit. By applying the Turnbull estimation method to our collected data, we estimate mean WTP of $21.73 for the proposed permit. Our estimates are sensitive to scope effects, which may be linked to perceived congestion: if hunters believe the bag limit may not be filled, WTP may actually decrease with the bag limit due to perceived congestion, necessitating the simultaneous examination of the bag limit and statewide quota.</p> <p><br></p> <p>Chapter 2: One Health initiatives employed by the Centers for Disease Control and Prevention place emphasis on the interconnectedness of animals, people, plants, and the environment. As new disease threats emerge, the interactions of humans and animals with their environments becomes increasingly important. Deer represent a large, prolific, and suitable host for several diseases that are potentially threatening in the One Health context. Previous works have studied deer-related diseases, such as Bovine tuberculosis and Lyme Disease, and examined risks of transmission in households of varying compositions, such as with and without pets or children. However, research quantifying public perceptions of deer and their role(s) in modern society is lacking. Our research applies social media listening to study perceptions of deer among the general U.S. population through volume (number of mentions) and assessment of tone, in terms of positivity versus negativity (analyzed as online media net sentiment). We study media about five prominent deer-related diseases from January 2018 through December 2021 and demonstrate that while aggregate mentions of the deer diseases we study compose a small proportion of total mentions for deer, net sentiment surrounding outbreaks reflects the seriousness of the health consequences these present. Additionally, we explain fluctuations in deer-disease mentions and net sentiment through real-world events, and demonstrate seasonality in mentions and net sentiment for some diseases of interest. Better understanding of public perceptions of the roles of wildlife, particularly deer who are generally perceived as non-threatening wildlife, is particularly important in today’s One Health context.</p> <p><br></p> <p>Chapter 3: The presence of deer in shared environments with humans may result in both positive and negative affinity towards deer. While literature shows deer-related damages to humans and their property, literature also suggests that deer are a way for humans to connect with nature. Managing deer populations is vital to balancing the positive and negative impacts of deer. Currently, hunting is the most cost-effective way to manage deer populations. We are interested in how hunting impacts the affinity for deer, in addition to how the COVID-19 pandemic plays a role in the perception of deer. Online media posts were analyzed using a social media listening platform, NetBase, for the time period of January 1, 2018 to December 31, 2021. Volume of mentions and affinity via net sentiment were collected at the state level on a weekly basis, and the national level on a daily basis. We utilize an OLS regression with dummies for deer hunting season and COVID at the state level to determine the impacts of hunting seasons and the pandemic on net sentiment. We find that deer hunting being open negatively impacts net sentiment of deer. We utilize Pearson correlations to study the impact of deer management via OTC deer hunting privilege issuance in relation to affinity for deer. We find that OTC privilege issuance is positively correlated with affinity for deer in some states, but the impact on affinity may diminish over time.</p>

This thesis seeks to investigate the influence and applicability of three technical writing principles across electronic maintenance manuals in the aerospace defense industry: military standard (MIL-STD) guidelines, plain language, and audience scope. Aerospace defense technical writers are liaisons tasked with coherent communication on advanced technological developments for technicians maintaining equipment. Their primary responsibility involves synthesizing specialized content from subject matter experts to draft comprehensive instructions for personnel safety and product sustainment during critical military operations. Current literature insufficiently examines the significance between aerospace defense technical documents and product performance following routine maintenance. Poorly composed manuals contribute to technician misinterpretation or disregard due to convoluted procedures and disorganized appearances increasing malfunction probabilities. Writing-based MIL-STDs and Simplified English emerged as efforts to mitigate understanding obstructs amongst domestic and international novice technicians. Maintenance manuals must conform to governmental guidelines including product liability laws, cultural variables, and audience expectations. Interview findings with two practitioners each from a different aerospace defense company supports the prediction that technical writing theories considerably impacts maintenance manual quality and recipience throughout the aerospace defense industry.

To determine the impact of an administrator's decision on student placement in kindergarten classrooms, teachers were asked to share their perceptions on how that decision impacted their ability to deliver instruction and follow the district scope and sequence, as well as how that decision impacts student academic achievement and social and emotional development. This qualitative study was designed to gather data from kindergarten teachers using focus group interviews and individual interviews of campus principals from two campuses within the same district. The following two ways in which kindergarten classrooms were created were explored: (a) by random assignment or (b) knowledge of students' academic and behavioral performance based on information relevant to their Pre-K experience. Campus principal participants reported that they each chose their method to provide equity in the classrooms and fairness amongst their teachers. Teacher participants reported that overall, they preferred to have as much information about incoming students as possible and to be a part of the process of placing students into classrooms for the following year. By examining these teachers' perspectives, the findings from this study may positively influence policy and practice for campus administrators as they decide how they will place students in kindergarten classrooms. Continued qualitative examination of student achievement could help determine if one method of placement positively impacts student achievement. Data collected from a larger sample within the district or expanded to compare between districts could help campus administrators make positive classroom placements for kindergarten students. Also, a quantitative study using a survey might provide a more expansive view of the impact of administrators' process of assigning kindergarten students to classrooms.

Industrial-organisational (I-O) Psychology is known for specialising in the study of human behaviour in the workplace (Van Vuuren, 2010). It is clear that the problems associated with individuals in the workplace form the basis for the existence of I-O psychology. Veldsman (2001) stated that it is imperative to reflect upon the future of I-O psychology and that I-O psychology must be repositioned in future. Therefore, it is emphasised that additional roles should be elicited for I-O psychologists in South Africa (Barnard & Fourie, 2007). Moalusi (2001) has recognised the need for I-O psychologists to reposition themselves in future by focusing on significant workplace issues. Upon further investigation it should be noted that many factors that exert an influence upon workplace behaviour do not necessarily derive from the workplace. These factors, such as family responsibilities, cultural influences and traumatic events, suggest that the sphere of influence of the I-O psychologists stretches far beyond the physical borders of the workplace (Landy & Conte, 2004; Van Vuuren, 2010). According to Strümpfer (2007), it is the I-O psychologist who is concerned with the deep-rooted problems of individuals. The objective of the study was therefore to critically review the role I-O psychologists play as counsellors, and to determine whether counselling should form part of the I-O psychologist’ scope of practice. A qualitative research design was utilised in the study following a phenomenology strategy. Convenience and snowball sampling were used to identify (n=22) I-O psychologists across the Gauteng and North West provinces. Semi-structured interviews were conducted, where the participants were asked to reflect upon seven interview questions which were later transcribed verbatim and analysed using content analysis. Nine themes were extracted from the data, namely, the meaning of counselling, counselling situations that I-O psychologists face, counselling skills required by I-O psychologists, characteristics displayed by I-O psychologist during counselling, counsellor competencies required of I-O psychologists, post graduate counselling training received by I-O psychologists, additional counselling training received by I-O psychologists, recommendations made for future training of I-O psychology students and lastly the inclusion of counselling in the scope of practice From the results it was clear the I-O psychologists are familiar with the meaning of counselling and that they are faced with a diverse range of counselling situations requiring a unique set of skills and competencies. Participants had divergent experience and opinions with regard to the training received in preparation of their role as counsellor. In relation to their training participants made recommendations for the future training of I-O psychologists. Finally, participants mentioned that it would be in their best interest if counselling is formally included in the scope of practice of the I-O psychologists. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2014

The existing audit risk model does not take business risk into account. The aims of this study are, firstly, to do research on the necessity of taking business risk into account in the audit risk model, and secondly, to indicate the influence of business risk on the audit risk model and on the scope of an audit. In this study, both audit and business risks were researched and it was determined that the existing audit risk model only considers the probabilities that auditors can give incorrect opinions. This study proposes a method whereby an auditor can consider both his own business risk and that ofhis client in determining an audit risk that is acceptable to him and in determining the scope ofhis audit. In addition to the probabilities of incorrect decisions by auditors the consequences thereof are also considered, thus limiting the auditor's engagement risk. / Die huidige ouditrisikomodel neem nie besigheidrisiko in ag nie. Die doel van hierdie studie is eerstens, om die noodsaaklikheid van die inagnerning van besigheidsrisiko in die ouditrisikomodel te ondersoek en tweedens, om die invloed van besigheidsrisiko op die ouditrisikomodel en op die omvang van 'n oudit aan te dui. In hierdie studie is literatuur oor ouditrisiko en besigheidsrisiko ondersoek waaruit aan die lig kom dat die huidige ouditrisikomodel net die waarskynlikhede in ag neem dat ouditeurs foutiewe menings kan uitspreek. Gevolglik stel die studie 'n metode voor waardeur 'n ouditeur beide sy eie besigheidsrisiko asook die van sy klient in ag kan neem tydens die bepaling van 'n ouditrisiko wat vir hom aanvaarbaar is en tydens die vasstelling van die omvang van sy oudit. Daardeur word nie alleen die waarskynlikhede nie, maar ook die gevolge van foutiewe besluitnemings deur ouditeurs oorweeg en 'n ouditeur se aanstellingsrisiko sodoende beperk. / Auditing / MCom (Ouditkunde)

To improve quality of software systems, change-based fault prediction and scope-bounded checking have been used to predict or detect faults during software development. In fault prediction, changes to program source code, such as added lines or deleted lines, are used to predict potential faults. In fault detection, scope-bounded checking of programs is an effective technique for finding subtle faults. The central idea is to check all program executions up to a given bound. The technique takes two basic forms: scope-bounded static checking, where all bounded executions of a program are transformed into a formula that represents the violation of a correctness property and any solution to the formula represents a counterexample; or scope-bounded testing where a program is tested against all (small) inputs up to a given bound on the input size. Although the accuracies of change-based fault prediction and scope-bounded checking have been evaluated with experiments, both of them have effectiveness and efficiency limitations. Previous change-based fault predictions only consider the code modified by a change while ignoring the code impacted by a change. Scope-bounded testing only concerns the correctness specifications, and the internal structure of a program is ignored. Although scope-bounded static checking considers the internal structure of programs, formulae translated from structurally complex programs might choke the backend analyzer and fail to give a result within a reasonable time. To improve effectiveness and efficiency of these approaches, we introduce local semantic analysis into change-based fault prediction and scope-bounded checking. We use data-flow analysis to disclose internal dependencies within a program. Based on these dependencies, we identify code segments impacted by a change and apply fault prediction metrics on impacted code. Empirical studies with real data showed that semantic analysis is effective and efficient in predicting faults in large-size changes or short-interval changes. While generating inputs for scope-bounded testing, we use control-flow to guide test generation so that code coverage can be achieved with minimal tests. To increase the scalability of scope-bounded checking, we split a bounded program into smaller sub-programs according to data-flow and control-flow analysis. Thus the problem of scope-bounded checking for the given program reduces to several sub-problems, where each sub-problem requires the constraint solver to check a less complex formula, thereby likely reducing the solver’s overall workload. Experimental results show that our approach provides significant speed-ups over the traditional approach. / text
