[pt] Devido ao ambiente competitivo entre as empresas, as exigências por redução de custo e maior entrega de valor ao cliente são crescentes. Desta forma, o gerenciamento efetivo da cadeia de suprimentos é cada vez mais necessário. Um componente essencial desta cadeia é o estoque, que possui dentre outras funcionalidades o papel de concretizar o atendimento da demanda do cliente final. Para tal, faz-se presente ao longo da cadeia de suprimento do cliente, edificações destinadas ao posicionamento e manuseio de estoques denominadas armazéns ou centros de distribuição. Estas instalações possuem atividade dinâmica, destacando-se a operação de picking, que corresponde por 50 porcento a 75 porcento dos custos de operação do armazém. O picking é o processo de coletar de seus locais de armazenagem os itens necessários para o atendimento dos pedidos dos clientes. Esta operação tem sido bastante impactada pelas recentes tendências do varejo devido à demanda cada vez mais complexa, maior variedade de itens e menor frequência de reposição. Um exemplo deste modelo, pouco explorado pela literatura, é o suprimento de lojas de conveniência. A partir desta carência de estudos, este trabalho pretende desenvolver um guia de avaliação de armazéns voltados ao suprimento de lojas de conveniência. Para tal, foi elaborada uma revisão de escopo da operação de picking e um estudo de caso contemplando três armazéns de duas empresas brasileiras com o intuito de demonstrar suas principais similaridades e diferenças. / [en] Due to the competitive environment among companies, the demands for cost reduction and greater added value for the customer are increasing. Therefore, effective supply chain management is extremely necessary. An essential component of this chain is the inventory, which has, among other features, the role of fulfilling the demand to the final customer. In order to support this, buildings are designed for positioning and handling inventories; they re called warehouses or distribution centers and are present throughout the customer supply chain. These facilities have dynamic activity, especially the picking operation, which corresponds for 50 percent to 75 percent of the warehouse s operating costs. Picking is the process of collecting the items needed to fulfill customer orders from their storage locations. This operation has been greatly impacted by recent retail trends due to increasingly complex demand, a greater variety of items and less frequency of replacement. An example of this model, little explored in the literature, is the supply of convenience stores. Based on this lack of studies, this work intends to develop a guide for evaluating warehouses aimed at supplying convenience stores. To this end, a scope review of the picking operation and a case study covering three warehouses of two Brazilian companies were prepared in order to demonstrate their main similarities and differences.

In Deutschland nimmt der Anbau von Bleichspargel (Asparagus officinalis L.) sechzehn Prozent der Gesamtgemüseanbaufläche ein. Die Qualitätssicherung von Spargel, insbesondere aber von geschältem (Convenience-) Spargel stellt wegen der hohen Stoffwechselaktivität nach der Ernte eine Herausforderung dar. Insbesondere gilt es, die Textur und die Inhaltsstoffe vor qualitätsmindernden Veränderungen und verderbsförderndem Pilzbefall zu bewahren. Als Verpackung dienen in der Regel Folienverpackungen, die aber oft für das empfindliche Gemüseprodukt nicht geeignet sind. Daher wurde der Einfluss von unterschiedlichen Folienverpackungen (vier Polypropylenfolien, zwei biologisch abbaubare Folien und ein Oberflächencoating) mit unterschiedlicher Permeabilität für Sauerstoff und Kohlendioxid auf die Veränderungen der Qualitätsparameter ( Farbe, Textur, Frischmasse, Trockensubstanz, Gerüstkohlenhydrate ( Pectine, Lignin, Hemicellulose, Cellulose, Saccharose, Fructose, Glucose) von nicht geschälten und geschälten Spargel unmittelbar nach der Ernte und nochmals nach drei (bzw. vier) Lagertagen (2°C, 10°C, 20°C Lagertemperatur) ermittelt. Direkt nach der Ernte und nach drei Lagertagen wurde bei 10°C und 20°C Lagertemperatur die Kontamination mit Pilzen und der eventuell damit verbundene Gehalt an Fumonisin B1 geprüft. Die Lagertemperatur von 10°C (2 d Lagerdauer) erwies sich als geeignet zur Qualitätserhaltung von Convenience – Spargel. Bei 2°C und 20°C geschältem Spargel waren die Pectinfraktionen, bei nicht geschältem Spargel war der Hemicellulosegehalt Veränderungen unterworfen. Die Veränderungen dieser Qualitätsparameter waren mit den Veränderungen der Textur korreliert. Die Spargelspitze ist bei der Lagerung (2°C und 20°C) stoffwechselaktiver, als die restliche Spargelstange. Es zeigte sich, dass das Verhältnis von O2 zu CO2 (RQ) in der Verpackungsfolie signifikanten Einfluss auf die Qualitätsparameter von geschältem Spargel ausübte. Die geringsten stoffwechselphysiologischen Veränderungen wurden bei einem RQ von 0,65 festgestellt. Folienverpackungen mit RQ von 0,03-0,65 hatten sich für das endophytische Pilzwachstum als hemmend erwiesen. Das Mykotoxin Fumonisin B1 wurden in gesundheitlich unbedenklichen Mengen (< 1,67 mg * kg TS-1) in nicht gelagerten und in gelagerten Spargelstangen nachgewiesen. / The production area of white asparagus comprises 16 % of all vegetable crops in Germany. The economic important asparagus (Asparagus officinalis L.) is known for its high quality loss in postharvest. In order to protect convenience asparagus, i.e. fresh-cut peeled white asparagus from rapid deterioration in respect to phytopathological fungi, nutritive and sensory compounds the commercial use of film packaging might be an important tool. However, the film packaging materials used commercially do often not fulfil product physiological concerns. Therefore, the influence of different film packaging materials (four polypropylene-films, two biological degradable films and one coating) with different permeabilities for CO2 and O2 was investigated for unpeeled and peeled white asparagus during storage (2, 3, and 4 days) at temperatures of 2°C, 10°C, 20°C. Changes in the following quality attributes were studied: colour, texture, fresh weight, dry weight, structural carbohydrates (pectic substances, lignin, hemicellulose, cellulose), mono- and disaccharides (fructose, glucose, sucrose). Moreover, at harvest and after three days of storage the contamination with fungi and the content of the mycotoxin Fumonisin B1 was observed. The tests for contamination of fungi were conducted with slight nutrient agar (SNA) for seven days at 20°C under 14 h UV light and 10 h darkness (Nirenberg, 1976) Quality changes were most inhibited at a storage temperature of 10°C for two days. The ratio of O2 to CO2 (RQ) within the film packaging had a pronounced effect on the quality attributes of peeled asparagus. Changes in dry weight, fresh weight, lignin content were low at a RQ of 0,65 (P-Plus 2 film), whereas the water-soluble/insoluble pectin ratio (1 : 0,8) remained constant during the entire storage period. A low correlation was found between texture and hemicellulose, glucose, sucrose and the ratio of water-soluble to insoluble pectin. The meristematic zone of the asparagus tip revealed a higher metabolic activity than other morphological parts of the spear. Endophytic fungi, e.g. Fusarium spp., a precursor of mycotoxin, was found in control asparagus spears. During storage, the development of Fusarium spp. could be inhibited by all film packaging revealing a RQ of 0,003 - 0,65. The mycotoxin Fumonisin B1 occurred in all asparagus spears (control and stored spears), however the content (< 1,67 mg * kg TS -1) did not reach health risk threshold values.

The general view of educators at all levels of education as well as trainers in industry, that learners do not have the ability to use their knowledge inter-curricular and holistically in their lives prompted the study. A very superficial study that was done in 2000, regarding the same problem, acted as the starting point for this study. The main purpose of the study was to determine the reasons for the general perception by educators that learners do not use their embedded knowledge in an inter-curricular manner. It also aimed to determine the most effective facilitating styles and methods that would help the learners to develop the skills to learn with the main aim to achieve learning that lasts and not just learning to pass. The use of deconstruction as a learning activity forms the biggest part of this qualitative action research project which was based on the main principles of the hermeneutic approach namely, communication followed by interpretation in order to reach understanding. The principles of narrative therapy were also used in the project. The hermeneutic approach followed in this study also allows the reader to walk the road with the participants as a narrative, first person reporting style provides rich background information regarding all the participants of the study as well as the contexts in which the actions took place. The reader will also be able to feel the closeness that existed between the educator and the learners who were part of this study. / Educational Studies / M.Ed. (Didactics)

This pilot study consists of two parts. The first part investigates the extent to which the domestic electricity consumers intend to use and use energy efficiently using the Theory of Planned Behaviour. The second part investigates the extent to which the Energy @ Home educational intervention changed the domestic electricity consumers’ behaviour. For the first part of the study an advertisement was published and a convenience stratified sample of 61 domestic electricity consumers were selected from the 290 respondents. Data was collected from the domestic electricity consumers via a questionnaire and a telephone response log. The co-relational research design was used to investigate the relationship between the predictor variables the independent variables in the constructs of the Theory of Planned Behaviour. Simple linear regression analysis resulted in F statistic for the predicted behavioural intention was 29.74 with a p value less than 0.0001 which indicates significant statistical evidence of a linear relation between the predictor variables and the independent variables. The r2 of 0.87 implies that data points that fall closely along the best fit line. Therefore the predictor variables were good predictors of the response variable. All the participants that intended to use electricity efficiently confirmed via the telephone that they were using electricity efficiently. In the second part of the study 11 out of the 61 participants were chosen to participate in the Energy @ Home educational intervention and television program. Data was collected via the Energy audit log and the electricity consumption log. The participants intended to save between 2% and 35% of their electricity consumption and the actual electricity consumption savings were between 2% and 30%. / Science and Technology Education / M.

Objectif. Décrire les attitudes et habitudes de Canadiens relativement à la préparation des aliments à la maison et au repas familial, afin de saisir les motivations à exploiter lors de la promotion de ces habitudes. Méthodes. Un sondage électronique de 39 questions à choix multiples a été placé sur le site des Diététistes du Canada du 16 novembre au 22 décembre 2006. Les énoncés analysés abordent la perception des bénéfices associés à la cuisine maison, à la planification des soupers et au repas familial, les obstacles à cuisiner, le temps de préparation et la planification des soupers, l’apprentissage de la cuisine, les sources d’idées recettes et la consommation des repas familiaux. Résultats. Au total, 4080 individus ont complété le questionnaire. Bien qu’ils croient que la cuisine maison puisse améliorer la qualité de l’alimentation et les comportements alimentaires, les répondants rencontrent plusieurs obstacles à la préparation des aliments au quotidien, parmi lesquels le manque de temps, d’énergie, d’idées et de planification. Bien qu’une majorité de Canadiens soupent en famille, il existe des écarts selon les groupes d’âge et les régions canadiennes. Conclusion. Cette étude souligne la pertinence d’élaborer des stratégies de communication pour informer les consommateurs sur les bénéfices de la cuisine maison et du repas en famille, afin de les aider à surmonter les défis associés à ces habitudes. Si les nutritionnistes sont des intervenants de choix, des collaborations interdisciplinaires sont proposées pour promouvoir une cuisine maison saine, bien planifiée, simplifiée et savourée en famille. / Objective. To describe Canadians' attitudes and habits with regard to home food preparation for family meals in order to seize the motivations to be exploited during the promotion of these habits. Methods. An electronic poll of 39 multiple-choice questions was posted on the Dieticians of Canada's website from November 16th till December 22nd, 2006. The analyzed statements cover the perception of the benefits associated with home cooking, supper planning and family meals, the barriers to cooking, the preparation time and supper planning, the development of cooking skills, sources of recipes ideas and consumption of family meals. Results. A total of 4080 individuals completed the questionnaire. Although they believe that home cooking can improve the food quality and eating habits, the participants meet several barriers to food preparation in everyday life, among which the lack of time, energy, ideas and planning. Although a majority of Canadians have family suppers, there are gaps according to age groups and Canadian regions. Conclusion. This study highlights the relevance of elaborating communications strategies to inform consumers of the benefits of home cooking and family meals in order to help them to deal with the challenges associated with these habits. If nutritionists are the best interveners, interdisciplinary collaborations are proposed to promote a healthy, well planned home cooking enjoyed with the family.

Suite à la croissance du phénomène migratoire clandestin, la prise de conscience publique et officielle de ce phénomène et du trafic des migrants est évidente. En conséquence, la signature du Protocole de l‘ONU contre le trafic de migrants et l‘adoption d‘une directive et d‘une décision-cadre au niveau européen sont conçues pour faire face à ceux qui profitent de ce phénomène, à savoir les trafiquants. Le droit français quant à lui, a accru la répression contre les tierces personnes impliquées, de près ou de loin, dans les activités clandestines de l‘immigration. Malgré l‘objectif affiché par ledit Protocole de « lutte contre le trafic illicite de migrants », les mesures adoptées et la large liberté laissée aux États membres, indiquent clairement le vrai but de cet instrument international, à savoir la lutte contre l‘immigration clandestine elle-même, but qui est le même pour l‘UE. Mais quel est le statut accordé par le protocole et par les dispositions européennes ainsi que françaises aux migrants qui font appel aux services des passeurs ? À travers cette étude nous pouvons entrevoir que la formulation des dispositions du Protocole et celle des dispositions européennes visent à n‘assurer aucun statut juridique aux migrants clandestins. Il n‘y a pas de statut juridique, ni victime, ni coupable, le migrant est en détresse. En revanche, en droit français, le migrant clandestin n‘est presque jamais regardé comme un homme, mais plutôt comme un délinquant. Le législateur français a choisi la loi pénale face à ces migrants. Cependant, les sanctions et la sévérité ne pourront rien contre un homme torturé, affamé, méprisé dans son pays. La loi pénale, à elle seule, ne permettra sans doute pas d‘apporter une solution. La préservation de l‘équilibre nécessairement fragile entre le respect de la liberté individuelle et le maintien de l‘ordre public est rarement prise en considération. En revanche les considérations économiques ont justifié une plus grande rigueur à l‘encontre des clandestins, au niveau de leur entrée, de leur séjour. / As a result of the ever increasing illegal migration phenomenon, Public opinion and officials are now clearly aware of it and of the trafficking involved. Therefore, the signing of the UN Protocole against the smuggling of migrants and the adoption of a directive together with a decision framework at European level are tailor made to fight against the traffickers taking advantage of this phenomenon. French law, as it is concerned, has increased repression against whoever might be involved in this clandestine smuggling and trafficking. Despite the objective stated in the, so called, Protocol of ―fighting against the smuggling of migrants‖ The measures adopted and the large freedom given to the members states, clearly indicate that the true purpose of this international instrument is indeed the same as the E.U‘s that is to say : fighting against illegal immigration. But what is the status granted by the protocol and the European as well as French provisions to the migrants who use the services of smugglers? All through this study we can see that the formulations of the provisions of the protocol and that of the European provisions are intended to ensure that no legal status is granted to clandestine migrants. As far as they are concerned they have no legal status so there is no victim and no offender: a clandestine migrant is just in distress. However in the French law a clandestine migrant is seen as an offender but not as a man in distress. The French parliament has chosen to enforce criminal law against these migrants but, will this stop migrants who are tortured, despised and starving in their country of origin? Choosing to see them only as offenders won‘t probably bring any solution to the problem. The necessary preservation of the delicate balance between respect for individual freedom and the maintenance of public order is rarely taken into consideration. However economic considerations justify rigour againt illegal immigrants concerning who is allowed to enter the country and how long they will be allowed to stay.

The thesis titled “The theory of thwarted belongingness and its relation to youth violence” presents the findings of a qualitative study that focussed on late adolescents who have committed physical assault and who were referred to a diversion programme by a court. The study followed a grounded theory methodology approach for which convenience sampling, purposeful sampling and theoretical sampling were used to obtain participants. Semi-structured interviews were conducted and the data were analysed through constant comparative analysis. From the analysis the theory on thwarted belongingness emerged that explains how the adolescents attempt to negotiate a sense of belonging. The theory further explains how failed negotiations are dealt with and when one could expect violent behaviour to occur. In general, the current research study creates awareness of the psychological non-shared environment and its potential role in the development of behaviour. Future research should be focussed on the saturation of categories and dimensions that have not been fully saturated in the current study and to test the theory of thwarted belongingness since it is a newly generated theoretical stance that needs to be validated. / Psychology / Ph.

The Diploma thesis ,Selected aspects of the retail supplier-purchaser relations' defines British grocery retailing. It presents government bodies which regulate retail industry and important independent not-for-profit organizations which have a strong influence on the market situation. It introduces the reader into legislation which regulates supplier-purchaser relations, particularly the Supermarket Code of Practice and its revised version the Groceries Supply Code of Practice. The analytical part examines the British market at the macroeconomical level, outlines the grocery retailing structure, describes the supply chain, customer behaviour, points out certain pricing and product policy trends and presents subjects which are bonded by the provisions set out in the Groceries Supply Code of Practice. The findings on local market competition and barriers which prevent the entry by a competitor are of a high significance as well. Despite the introduction of legal regulation the supplier-purchaser relations remain unequal and unfair. The thesis proposes a forecast of possible future grocery market development in the United Kingdom.
