Since the early 1990s, the rapid growth of international hotel chains and its effects on managerial work have drawn the attention of researchers (Gilbert & Guerrier, 1997 and Ladkin & Juwaheer 2000). There is a current need to investigate how management in hotels is adapting to the significant change in the last decade (McKenney, 2016). The contemporary Hotel General Manager’s (HGM’s) role, responsibility, and ultimately autonomy, are seen to be largely influenced by the owners, management companies or the franchise the hotel is operating under. “Understanding the scope and limits of HGMs decision autonomy is an understudied yet important topic for hospitality research” Hodari & Sturman, 2014 p.434 How management is practiced at the highest level in the hotel is the research problem to be investigated. Kotter (2010), Whitley (1989) and Hales (1986) emphasised how the nature of managerial work is closely linked to its organisational context. Accepting that managerial work is shaped and exercised in context (Dierdorff et al, 2009; Akrivos, Ladkin and Reklitis 2007), the aim of this research is to explore and understand the way in which contemporary HGMs manage and what influences how they manage. This work aims to shed light on hotel general management across three contemporary business models in the operating environment of Aberdeen city and Aberdeenshire. The research strategy will be interpretivist, with a qualitative approach taken to elicit HGMs’ experiences about their working life and chosen activity to understand the influences on their management practice. Dann (1990), credits Hales (1987) with providing a methodology, which allows the conduct of managerial work to be placed within the context of the management process. On account of this Hale’s five broad questions are built into the interview schedule. Semi-structured face-to-face interviews are held with HGMs who were members of the Aberdeen City and Shire Hotel Association. This Association has a membership of thirty-eight hotels operating through private, chain and franchise models. In total 21 HGMs are interviewed. From this data a profile of the HGM is provided, as found in each of the three ownership/business models (private, chain and franchise). The data were analysed by the constant comparison method. This study contributes to the body of research through looking at what HGM’s actually do, and how these individuals practice management. This work provides new knowledge in the form of a model, which maps out the identified management context (characteristics) that influence HGM behaviour/activity and the consequences for management across business models surveyed. The business model under which the HGM manages is found to be the primary influence on HGM activity and behaviour. The work sheds light on the meaning of work, and why it is the way it is. At the first level of analysis management context across three business models is identified. These then map onto the second level of analysis, which explains how these influences shape management behaviour and activity. The model identifies consequences for management across the business models. The proposition in the study is that HGMs have not been de-skilled; they have instead prioritised skills and activity in line with the demands of the business model and the ownership style under which they manage. In effect new skills have been learnt, and behaviour and activity tailored to meet the contemporary demands in context of the business model. This research has found that although HGMs have the same title, they are found to be very different managers that are managing different things. Not only do the HGMs manage differently the priorities of management are also quite different. The contribution to knowledge is considered at theoretical and practical levels. At the theoretical level a modern take on Taylorism shows that specialisation is relevant to contemporary hotel management. Silos are created on account of the business models, with markedly different ways of hotel services being delivered. The priorities of HGMs, dictated by the business model, are different. The extreme cases being the people centric, long term focus of the private sector manager juxtaposed with the short financial term focus by the chain HGMs. At the practical level, accepting that hotel general management is not homogeneous, and driven by the business model, hotel organisations need to develop their own organisationspecific competency framework for their HGMs. Success across the business models is measured differently; for chain and franchise HGMs there is a need to generate higher gross profits and for results to reported frequently, and for the private sector HGMs success is linked to long term sustainability, serving the community and providing a personal service. A challenge for each HGM in each of the models is managing stakeholders. These stakeholders vary with the model; managing the owners and operating company superiors are vital in chains, while the customers and staff are more important to HGMs in private model. For HGMs in both chain and franchise business models activity and behaviour is influenced by the need to ensure brand compliance through standard operating procedures.

Master of Science / Department of Biological and Agricultural Engineering / Aleksey Sheshukov / The global requirements for food and agricultural products have increased enormously in recent years mainly due to increase in global population. More land is brought under human development and cultivation including marginal lands that are susceptible to degradation processes of erosion, waterlogging, and depletion of organic matter. The resulting effects include; deprivation of the roles performed by the environment, high costs of water treatment, and sedimentation of water reservoirs. This study aims at assessment of ephemeral gully (EG) erosion using topographic and hydrologically based models in two paired watersheds in Central Kansas. The effects of best management practices (BMPs) implementation on EG formation, and erosion rates within the watershed are discussed. The topographic index (TI) models used include: slope area model (SA), compound topographic index model (CTI), wetness topographic index model (WTI), slope area power (SA2), kinematic wave model (nLS), and modified kinematic wave model (nLSCSS). EGs predicted by each model threshold were compared with observed EGs obtained through digitization and field reconnaissance. The agreement of thresholds obtained from location and length approaches were compared by means of drainage density concept. Statistical analysis was performed by error matrix for EG location analysis, and root mean square error (RMSE) and Nash–Sutcliffe efficiency (NSE) for EG length analysis. A TIN-based real-time integrated basin simulator (tRIBS) model, a physically-based, distributed hydrological model was coupled with an EG erosion component (Foster and Lane model) to estimate the erosion rates, and effect of installation of BMPs on reduction of EG erosion rates from agricultural fields. The results indicated that TI models could predict EG location with a maximum total accuracy of 70%. The effectiveness of TI models at prediction of EGs is affected by watershed features such as installed structural best management practices, roads, and culverts. The CTI model outperformed all the TI models at prediction of EGs with maximum Kappa and NSE values of 0.32 and 0.55 respectively, and a minimum RMSE value of 0.087 m. Structural BMPs are effective at controlling erosion from croplands, however, the effectiveness of structural BMPs at reduction of sediment loadings from EGs vary depending on surface cover, and BMP geometry.

Knowledge management (KM) has become a vital part of the successful development of private and governmental organizations. KM is processed tools and behaviors that participate in the formulation and performance of the beneficiaries of the organization, acquisition, storage and distribution of knowledge. This is to reflect on the business processes and to gain access to best practices with a view to long-term competition and adaptation. In this context, the personal understanding of KM is a key factor in successful employments of KM activities. In this thesis, the level of understanding of knowledge management and the extent of its usage in the university library by librarians was investigated. A comparison study was established between libraries in developed and developing countries. Interviews and observations were performed and the results were analyzed. The results indicate the concept of KM is hardly known, however it is employed to different extent between these counties, the developed countries were by far more successful in utilizing current technology to advance their service and personal expertise with few challenges. Lack of communication, knowledge sharing, and the shortage in the budget was essential in limiting the usage of KM in developing counties. The knowledge derived from this thesis advances an understanding of the importance of KM in library performance, thus presenting the basis for improving libraries in developing countries and advancing libraries in developed countries.

Monitoring of a regional stormwater management facility, located on the Virginia Tech campus in Blacksburg VA, was conducted in order to assess its efficacy in reducing nonpoint source pollutant losses downstream. The facility design includes both an upper water quality (wet) pond and a lower 100-yr-event quantity (dry) pond. These on-stream ponds capture both baseflow and storm runoff from the southern portion of the Virginia Tech campus and surrounding lands, and release the water back to the unnamed stream shortly above its conjunction with Stroubles Creek, a tributary of the New River. Monitoring sites for flow measurement, water quality sampling, and biotic assessments (habitat evaluation and rapid bioassessment of benthic macroinvertebrates) were located above and below each of the ponds. Both grab samples and automated samples were collected at these stations. Between 1997 and 1999, water quality grab samples included 35 baseflow samples and 22 stormflow samples. The grab samples were analyzed for concentrations of total suspended solids (TSS), metals, bacteria, and nutrients as well as temperature, pH, dissolved oxygen, conductivity, total organic carbon (TOC), and chemical oxygen demand (COD). Automated flow-weighted sampling was initiated in February of 1999 and results are reported through the end of October 1999. Thirty-three storms in 1999 were monitored for flow and various water quality parameters (TSS, TOC, COD, and nutrients). Pollutant loads and pollutant removal estimates were calculated with regard to the wet pond, dry pond, and the combined facility. Two types of pollutant removal efficiencies were calculated: (1) the EMC efficiency, based on pollutant concentrations from individual storms; and (2) the SOL efficiency, based on pollutant loads, to estimate long-term performance over the study period. Benthic macroinvertebrate sampling and habitat assessment were performed in both 1997 and 1999. In addition, a preliminary investigation of pond characteristics was conducted, including measurements of water quality and composition, sediment deposition and composition, and residence time. As a system, the stormwater management facility appears to have minimum impact on improving the downstream water quality. Pollutant concentrations and loads both appear to increase downstream of the facility as compared to upstream, during both storm event and baseflow periods. Monitoring results of the benthic assemblages showed evidence of moderate to high impairment at all sampling locations, and habitat assessments showed evidence of high sedimentation levels within the stream, even after installation of the stormwater management facility. Total suspended solids (TSS) concentration removal efficiency was 10% for the combined wet pond and dry pond system, much lower than the 80 to 90% TSS removal expected for properly functioning stormwater management facilities (Hartigan, 1989). There is some evidence of sedimentation within the ponds because of a slight reduction in sediment-bound constituent export, but the dissolved nutrient constituents had either very low and most often negative (indicating pollutant export) removal efficiencies. Concentrations of metals measured in the stream often exceeded their respective acute and chronic water quality criteria at all sampling locations. Pollutant removal efficiencies measured in the wet pond are atypical of those reported in the literature (Schueler, 1993). Insufficient residence time (two days compared to the optimal two weeks), and wet pond embankment failure are likely the principal causes of the wet pond's inadequate performance and thus, the inadequate performance of the overall facility. TSS removal efficiencies were low in the wet pond (19% for concentrations and 33% for loads) compared to the 80 to 90% expected for similar ponds. Nevertheless, the wet pond reduced the concentrations of several pollutants typically associated with TSS and not likely to be associated with the fill material for the wet pond embankment. Zinc concentrations in sediment cores were highest near the pond inlet, where the majority of sedimentation occurs. During storm events, the following results were noted. Copper and zinc concentrations in 1998 were lower at the pond outlet as compared to the pond inlet, and TOC concentrations and loads were also reduced by the wet pond (13% for concentrations and 12% for loads). However, sedimentation is also expected to remove phosphorusl, and wet pond phosphorus loads were only reduced by 10% and 3% for orthophosphorus and total phosphorus, respectively. Because the wet pond is undersized with respect to the watershed it serves (surface area less than 1% of the watershed area (0.87 ha), as compared to the 3% ratio often recommended for optimal pollutant removal (Athanas, 1988)), higher removal efficiencies were found during baseflow periods. The greatest reductions in baseflow concentrations were for ammonia (67%), nitrate (57%), total nitrogen (54%), and COD (45%). However, the residence time of two days appears to be insufficient to reduce fecal coliform concentrations in the stream, and over 40% of the fecal coliform samples collected exceeded the water quality standard for contact recreation (DEQ-WQS, 1997). Furthermore, the wet pond did not appear to reduce TSS or TOC during baseflow periods. Export of TSS (-29% EMC efficiency) and TOC (-44% EMC efficiency) from the wet pond during baseflow periods is likely due to the wet pond embankment failure as well as pond eutrophication. Eutrophication processes are favored by the water temperature increase as flow passes through the shallow wet pond. The wet pond increased downstream temperatures by approximately 8°C above inflow temperatures during the summer, and to levels above 21°C which cannot be tolerated by sensitive coldwater species (Schueler, 1987). The dry pond did not remove dissolved nutrient constituents or other pollutants during baseflow periods, but there is some evidence of sedimentation within the dry pond during storm events. During storm events, the dry pond was effective in removing TSS, with a concentration removal efficiency of 69% (EMC efficiency) and loading removal efficiency of 43% (SOL Efficiency). Removal of TKN and total phosphorus (36% and 37% respectively for concentrations) within the dry pond is further evidence of sedimentation within the dry pond. The wet pond embankment was built in 1997, and monitoring occurred during a potential stabilization period when evidence of water quality benefits are slow to appear, especially with respect to downstream habitat and aquatic communities. Some benefits which could have been observed more immediately may have been negated or masked by the progressive erosion of the wet pond embankment as a result of a design flaw. Further complicating the results is the appearance; based on observations of extended drawdown time and results from a water budget analysis in the wet pond (where inflow substantially exceeds inflow); that groundwater interacts with the pond in a complicated fashion, possibly including both recharge and discharge. To fully understand the impact of the stormwater management facility on the water quantity and quality within this tributary of Stroubles Creek, monitoring efforts should continue after the wet pond embankment is repaired and is fully operational. If biotic community improvement is desired, the stabilization period could be defined by the time necessary to flush out accumulated sediment within the channel. Monitoring efforts should also expand to include the investigation of the groundwater regime and water level fluctuations within the wet pond. Further measurements of pollutant removal processes and influences upon those processes within the wet pond should also be considered. Last, the influence of the stormwater management facility on downstream flow regimes should be investigated to assess the adequacy of its performance with regard to flow control and prevention of stream channel degradation. / Master of Science

Accurately delivering and precisely timing sprinkler irrigation improves peanut yield and profitability, but there are no data on how to achieve this in the mid-southern USA where furrow-irrigation dominates. This research was conducted to determine if soil water potential could be manipulated through land preparation method, irrigation delivery, and irrigation scheduling. The effects of land preparation method (flat vs bed), furrow-irrigation delivery (every vs every-other furrow), and irrigation scheduling [Food and Agriculture Organization and drainage paper 56 (FAO-56), - 50 kPa, -75 kPa, and -100 kPa] on peanut yield, net returns above irrigation costs, and irrigation water use efficiency were investigated near Stoneville, MS on a Bosket very fine sandy loam. Our data indicate that regardless of land preparation method, peanut yield, net returns above irrigation costs, and irrigation water use efficiency are most often optimized in the mid-southern USA by irrigating every other furrow at a threshold of -50 kPa.

Stream ecosystems are increasingly at risk for thermal impairment as urbanization intensifies, resulting in more heated runoff from impervious cover that is less likely to be cooled naturally. While several best management practices, including bioretention filters, have been able to reduce thermal pollution, success has been limited. The extent of thermal mitigation required to prevent ecological damage is unknown. A calibrated runoff temperature model of a case study watershed in Blacksburg, VA was developed to determine the cumulative treatment volume of bioretention filters required to reduce thermal impacts caused by runoff from development in the watershed to biologically acceptable levels. A future build out scenario of the study watershed was also analyzed. Results from this study established that runoff thermal pollution cannot be fully reduced to goal thresholds during all storms using bioretention filter retrofits. While retrofitting significantly decreased temperatures and heat exports relative to the controls, increasing treatment volumes did not really enhance mitigation. Alternate thermal mitigation methods which actively remove runoff volume should be considered where more thermal mitigation is required. / Master of Science / Stream temperature is a significant ecological, biological, and chemical property affecting the long-term health of streams. However, as development intensifies, stream ecosystems are increasingly at risk of being damaged by thermal pollution, which causes warmer and less stable temperatures that distress aquatic organisms. While several stormwater management methods that reduce runoff-related pollution, known as best management practices (BMPs), were found to also decrease thermal pollution, their success has been limited. Furthermore, the extent of thermal mitigation required to prevent ecological damage is unclear. This study aimed to determine how much treatment by a popular BMP, the bioretention filter, was necessary across a watershed in Blacksburg, VA to adequately reduce thermal pollution to protect stream health. Mitigation impacts were tested on both existing and predicted future development conditions through model simulations. Results from this study established that thermal pollution from runoff cannot be fully reduced to goal thresholds consistently using bioretention filter retrofits. While retrofitting significantly decreased thermal pollution, increasing treatment volume did not considerably enhance mitigation. Results suggested that bioretention filters are not an effective method, and alternate thermal mitigation practices which actively remove runoff volume should instead be considered where intensive reductions in thermal pollution are necessary.
