A mudança nos hábitos dos brasileiros, optando por consumir alimentos prontos, tem estimulado o crescimento das indústrias nacionais. Neste cenário, o processamento industrial da batata é uma forma de agregação de valor à hortaliça e retorno financeiro ao produtor, visto que a matéria-prima destinada à indústria apresenta maior valor no mercado. O segmento da batata-palha, por exigir baixo investimento, tem se fortalecido. Porém, para sua consolidação é imprescindível o desenvolvimento de pesquisas visando ampliar as alternativas de materiais genéticos disponíveis aos produtores e processadores de batata-palha. O objetivo da pesquisa foi avaliar o desempenho agronômico e industrial de cultivares de batata em três ambientes de cultivo nas condições edafoclimáticas do Sul do estado de Minas Gerais; avaliando o desempenho destas quanto a produtividade e adequação ao processamento na forma de batatapalha. As cultivares avaliadas foram: Caruso, Destiny, Excelence, Fontane, Markies e Saviola. O experimento foi conduzido no período de dezembro de 2012 a maio de 2013, nas condições ambientais de Gonçalves, Lambari e Nova Resende. O delineamento experimental foi em blocos ao acaso, com seis tratamentos (cultivares), quatro repetições. Foram avaliadas características de produção total, comercial, de tubérculos grandes, médios, pequenos e porcentagem de refugos em relação à produção total; de qualidade para fritura como conteúdo de matéria seca e de açúcares redutores, rendimento de fritura, cor após a fritura e a absorção de gordura pela batata frita e aplicados os testes sensoriais afetivo de aceitação através de escala hedônica estruturada e de preferência por ordenação. Observou-se diferença no desempenho das cultivares entre os ambientes de cultivo. \'Caruso\' e \'Destiny\' foram as que mais se destacaram na maioria dos atributos avaliados. / The change in the Brazilian consumers\' habits, preferring prepared foodstuff, have been stimulating the growing of the national food industries. In this scenario, the industrial processing of potatoes is a good option to aggregate value to this crop and increase the financial feedback of the producers. The shoestring potato segment is being strengthened because it demands low investment. However, for its consolidation is vital the development of researches aiming to expand the alternatives of genetic materials available for the shoestring potato producers and processors. Our aim in this work was to study different potatoes genotypes in three farming environments under the edaphoclimatics conditions of the South region of Minas Gerais State (Brazil) and the performance and adequacy of these genotypes for fried processing of shoestring potato. The cultivars evaluated were: Caruso, Destiny, Excelence, Fontane, Markies and Saviola. The assessment was conducted from December 2012 to May 2013 in Gonçalves, Lambari and Nova Resende districts. The experimental design was in random blocks with six treatments and four replicates. Besides the total and commercial production, also were evaluated the production of large, medium and small tubers; fry quality and yield were based on dry matter content, free sugars levels, color after fried and fat absorption by the fried potatoes. Affective sensory acceptance tests were applied using the structured hedonic scale and the preference for ordination. Differences in the performances among the cultivars and farming environments were observed. \"Caruso\" and \"Destiny\" outstand in all the attributes assessed.

O mercado brasileiro de processamento de batata tem mostrado expressivo crescimento nos ultimos anos. No entanto, sua expansao e condicionada pelo suprimento de materia-prima adequada ao processamento industrial. As principais industrias de batata frita priorizam cultivares aptas para cada forma de processamento, pois a escolha correta da cultivar contribui para a reducao do custo de producao e para o aumento do rendimento e da qualidade do produto final. O objetivo dessa pesquisa foi estudar a eficiencia produtiva, a aptidao culinaria e as caracteristicas das cultivares de batata quando processadas na forma de palha e chips. Avaliou-se nove cultivares de batata: Agata, Almera, Arizona, Caruso, Destiny, Excelence, Fontane, Markies e Saviola. \'Agata\' e \'Almera\' foram utilizadas como cultivares nao aptas para fritura e \'Fontane\' e \'Markies\' como cultivares recomendadas para fritura. O ensaio foi conduzido no periodo de janeiro a maio de 2013, nas condicoes ambientais de Nova Resende, na regiao Sudoeste de Minas Gerais. As cultivares Arizona, Caruso, Agata e Markies exibiram o maior potencial produtivo e, junto a Saviola, a maior producao de tuberculos comerciaveis. Os teores mais elevados de materia seca foram exibidos por \'Destiny\' e \'Caruso\' (superior a 20%), seguidas por \'Excelence\', \'Fontane\' e \'Markies\' (17 a 18%). \'Caruso\' proporcionou o maior rendimento de fritura em ambas as formas de processamento. As cultivares Destiny, Excelence (ambas com cor amarela extremamente clara apos a fritura), e Caruso (cor dourada) na forma de palha; e Caruso e Destiny (cor amarela clara a dourada) na forma de chips apresentaram baixos teores de acucares redutores. Entre as cultivares avaliadas a maior eficiencia produtiva de materia-prima com aptidao para fritura foi exibida por \'Caruso\', \'Destiny\' e \'Excelence\', sendo que todas sao aptas ao processamento na forma de palha. Ja na forma de chips somente \'Destiny\' e \'Caruso\' proporcionaram fritas adequadas. / There is an increasing market for potato processing in Brazil, and the expansion of the potato industry can only be sustained if good quality product supplies of raw material are available. To reduce production costs and increase industrial efficiency, the industry must choose appropriated cultivars for each kind of product. This research investigated the tuber yield, frying aptitude, and the potato quality attributes for shoestring and chips. Nine potatoes cultivars were evaluated: Agata, Almera, Arizona, Caruso, Destiny, Excelence, Fontane, Markies and Saviola. \'Agata\' and \'Almera\' were considered unfit for frying, \'Fontane\' and \'Markies\' with frying standards. The trial ran from January to May 2013, in the south-west region of Minas Gerais State, Brazil. The cultivars Arizona, Caruso, Agata and Markies exhibited higher yield potential. These cultivars and Saviola obtained the highest marketable tubers. \'Destiny\' and \'Caruso\' showed the highest dry matter contents (higher than 20%) and were followed by \'Excelence\', \'Fontane\' and \'Markies\' (17- 18%). \'Caruso\' showed greater industrial efficiency for shoestring and chips. \'Destiny\', \'Excelence\' (extra light fries) and Caruso (medium light) for shoestring, and Caruso and Destiny (extra light to medium light) for chips showed low contents of reducing sugars. It was concluded that \'Destiny\', \'Excelence\' and \'Caruso\' outperformed all other cultivars in terms of yield. Besides, these varieties also displayed aptitude for shoestring frying. On the other hand, \'Destiny\' and \'Caruso\' were apt to frying as chips.

This research explores the relationship between the organisational culture and financial performance of a South African investment bank by means of quantitative research. The Denison Organizational Culture Survey was used to measure the organisational culture of the investment bank and was administered to a sample of 327 employees. Income statement ratio analysis was selected as a means to assess the financial performance. The results indicate that very few of the financial measures selected could be shown to be correlated with the organisational cultural traits or subscales. Correlations between the cultural dimensions of team orientation, agreement, customer focus and vision were found with certain financial measures. Although these correlations were above the 0.50 level, the levels of significance were not sufficient in all cases to draw conclusions with confidence. The only cultural trait that was found to be correlated with financial measures was the consistency trait. / Industrial and Organisational Psychology / M.Com.

Organizations specifically the airlines industry are increasingly facing the challenges of operational efficiency measurement. During the last years enormous attention has been given to the assessment and improvement of the performance of productive systems. However, literatures show that there are limitations of the existing models to measure efficiency uniformly and exhaustively across the airlines. The problems are due to lack of the technical efficiency measuring model which unifies and integrates different measuring models into a single model.Therefore, this thesis investigates assessment of the operational performance of world major airlines by employing integrated comparative models to address the above problems. In this study, technical efficiency is addressed among many performance issues by using three types of modes of performance measurement: a non parametric one, represented by Data Envelopment Analysis (DEA) and; a parametric one, represented by Stochastic Frontier Analysis (SFA) and the Balance Scorecard (BSC) which is a strategic management tools. Unlike most of the previous studies, this study integrates the BSC concepts into DEA and SFA model. To evaluate technical efficiency of major international airlines, the study use panel of unbalanced data for the year 2007-2014 to make integrated comparative analysis. The research project incorporates seven leading variables and four lagging variables taken from BSC concept to implement into the DEA and SFA. All the three models of performance measurements have their own strength and limitation if they are used alone. But if the three models are integrated and combined together, they would yield better comparative and quality of efficiency assessment. Therefore, the study primarily developed a model beginning from the theoretical framework assumption into building of a unified comparative model of integrated comparative operational efficiency assessment of airlines. The research design and methodology uses secondary data collection i.e. annual reports and business reports of airlines which are collected from the airlines own website. The huge amount of financial and operational data cannot be collected by using primary data collection method as it would make it practically impossible and expensive. So by employing secondary data collection method saves time, money and a panel data can be accessed and generated easily. Hence, from 100 world major airlines population which are ranked by revenue, simple random sampling is used to select 80 samples airlines for this study. First, the BSC identifies the input and output variables. Next, the DEA model ranks the efficiency measurement, identifies the slack variables and benchmarks the airlines. Third, the SFA model identifies technical efficiency, the random error and technical inefficiency. Finally, the technical efficiency estimates obtained from the two techniques are analyzed comparatively. The research makes further analysis of particular case of the Ethiopian Airlines in relation to the most efficient and inefficient airlines and in comparison of the regional analysis. After extensive tests have been conducted, ‘Balanced Frontier Envelopment’ model is developed. According to this model, it is a paramount to measure efficiency with combining the strength of three models together and gives better results than the previous one or two combined models. The developed and integrated strategic model enhances measuring of the operating technical efficiency of airlines. This model benefit the airlines industry in many ways such as minimizing the cost and maximizing profit through managing technical efficiency which lead into the success of the airlines. From the model perspective, therefore, result of DEA model is much higher than the result of SFA model. DEA model is easier to manipulate than the SFA model because the former does not need the functional form while the later requires a functional form. Furthermore, according to the efficiency finding of the study, first, the European regional airlines are relatively more efficient than the rest of regions in the world. Second, the North America regional airlines are the second more efficient regional airlines in the world. Third, the Ethiopian airlines are the most efficient in Africa when we compare among Egyptair, Kenyan Airways and South African Airways. Fourth, high revenue does not necessarily leads to the technical efficiency of the firm. / Business Management / D.B.L. (Business Leadership)
