There is very little focus in previous research on first language (L1) use by teachers in the upper secondary English as a foreign language (EFL) classroom from the students’ perspective. In this context and from a Swedish perspective, this thesis examines what attitudes students in the Swedish upper secondary school have towards their teachers’ use of L1 (Swedish) in the EFL-classroom. The method used was qualitative semi-structured interviews, where nine students in total were interviewed. The collected data was then coded, thematized and categorized. The results show that the students mainly believed Swedish should be used when teaching vocabulary, when teaching grammar and for classroom management. They did not believe the L1 should be used by them in questions and answers and in general talk in the classroom. They also endorsed an overall judicious use of Swedish by their teachers and that their use of this language should be adjusted to the specific teaching group. Finally, it can be concluded that further research is needed on how the L1 can be used judiciously in particular situations and on what attitudes students of varying proficiency and age, as well as students who do not have Swedish as their L1 have towards teachers’ L1 use in the EFL-classroom.

Maine sporting camps were a cultural and social phenomenon of the urban upper and middle class. They originated in Maine in the late 1870s and early 1880s and reached their zenith around the turn of the century with over 160 in operation in eight of the sixteen counties in Maine in 1906. The period from 1880 until World War I can be considered the 'golden era' of the Maine sporting camps. After the war, with technological advancements such as the outboard motor, the proliferation of the automobile, and the introduction of a road system into rural Maine, the camps underwent significant change that warrants an entirely different cultural analysis. A number of elements came together to produce a cultural atmosphere permissive of sporting camp creation in Maine. These include changing national views upon nature, health, sport and the leisure time in which to pursue them. In the late nineteenth century, with the rise of large industrially based cities, overcrowding fostered crime and disease. An upper and middle class emerged that desired escape and separation from the lower classes. Maine was chosen for such an escape because it offered, through sporting camps, a chance to "get back to nature," by pursuing the healthful activities of hunting and fishing. At the same time these urban sportsmen and sportswomen distinguished themselves on the social Hierarchical scale from the rural inhabitants. What happened in rural Maine during the period between 1880 and World War I was the introduction of a new cultural order on the landscape. Coming primarily from urban centers on the East Coast of the United States were men, women and children who looked to Maine for vacations. These vacations were designed to put them in touch with nature by pursuing healthful activities, especially those of fishing and hunting. Coming from an environment that emphasized social standing, they ensured that these trips would perpetuate this hierarchy. They experienced nature through the Maine sporting camps, which provided them with the services and skills necessary to experience it while enjoying a degree of luxury that they were accustomed to in the urban world. The Maine sporting camps were a cultural manifestation of the urban upper and middle class, the groups that the camps were established to serve. Despite this the camps did not represent a structural duplication of urban society. Instead, the camps represented a cultural construction that was produced by interaction between members of two different conceptual and physical worlds, the blending of which, on a social level, was determined by urban mentality and rural knowledge. In the production of a cultural world meaningful to the clients, the rural world of the Maine woods was altered to meet their needs. It was not a one-sided process, however, as the clients were forced to acknowledge the importance of the rural inhabitants on the basis of their value to the clients.

Esta investigação visa o melhor entendimento do fenômeno do crowding em lojas, dentro do contexto do mercado brasileiro, procurando identificar como as respostas dos consumidores variam entre os de renda baixa e renda alta, e buscando fatores que possam melhor explicar essas diferenças. Para atender esses objetivos, adotou-se uma metodologia experimental para testar como o aumento da densidade humana afeta diferentemente as respostas dos consumidores de alta e baixa renda. Como moderadoras da relação entre densidade humana e as respostas de consumidores, utilizaram-se as variáveis renda (alta e baixa) e familiaridade (alta e baixa). Três experimentos de desenhos fatoriais permitiram o teste das hipóteses propostas, por meio de análises multivariadas: ANOVAs, ANCOVAs e regressões lineares. Os estudos demonstraram que renda efetivamente modera as respostas dos consumidores, pois existe substancial diferença entre os consumidores de alta e baixa renda para situações de alta densidade humana em lojas. Foram verificadas as seguintes respostas dos consumidores com menor renda em situações de alta densidade humana: atitude mais positiva e maior nível de satisfação do que os de alta renda; percepção de maior valor hedônico em lojas mais cheias de gente versus os de maior renda. Os resultados contrariam a maioria dos achados de estudos realizados nos Estados Unidos nas últimas décadas. Enquanto a maioria desses estudos indica uma resposta negativa à densidade humana, os resultados desta pesquisa evidenciaram que existem respostas mais positivas para o segmento econômico de consumidores de baixa renda. Constatou-se também o efeito moderador do controle informacional (familiaridade) na relação entre densidade humana e as respostas dos consumidores, e o efeito mediador da percepção de valor hedônico na relação entre densidade e satisfação. Os achados oferecem uma contribuição teórica para enriquecer o entendimento do fenômeno de crowding e ressaltam a importância de se considerar a diversidade do contexto socioeconômico para se garantir o desenvolvimento de generalizações que corretamente reflitam as várias realidades do mercado. Do ponto de vista gerencial, o estudo reforça a necessidade de o varejo desenvolver uma maior distinção em ambientes de loja para melhor satisfazer as diferentes preferências dos diversos segmentos de mercado.

In order to achieve better postures and decrease musculoskeletal risks adequate design of hand/box couplings for manual materials handling (MMH) are still needed. No studies evaluating upper limb movement thorough direct measurements during box handling in workplace were identified in the literature. In this study we describe the types of grip and movements adopted by ten workers when handling redesigned boxes with cutout handles between different heights on industrial pallets. The new handles were used by 90% of the workers through different types of grip. Electrogoniometric measurements showed relatively safe forearm and wrist movements, although elbow inadequate range of movement was recorded. Despite the good acceptance of the cutout by workers, the new design requires extra internal space in the boxes reducing applications for this alternative of box.

Purpose: To describe spontaneous blink kinematics in Graves' upper eyelid retraction (UER).Methods: The magnetic search coil technique was used to record spontaneous blinks of 15 healthy subjects (aged 23-56 years, 15 eyelids) and 15 patients with Graves' UER (aged 22-62 years, 15 eyelids) during a 5-min period of video observation, and the signals were digitized at 200 Hz (12 bits). Overall, a total of 2,798 blinks were recorded for the controls and 1,860 for the patients. The distance between pupil center and upper eyelid margin in the primary position of gaze (MRD) was measured with the Image J software.Results: The blinking rate of patients was lower than that of control subjects, with a mean (+/-SEM) blinking rate (blinks/min) of 13.0 +/- 1.7 for patients and of 20.0 +/- 2.1 for the controls (t = 2.58, P = 0.016). There were no statistically significant differences in blink amplitude between controls (22.7 +/- 3.1 degrees) and Graves' patients (24.7 +/- 3.3 degrees). However, while only 22% of the blinks performed by controls were smaller than MRD, this rate was 78% for patients. In addition, in blinks larger than 25, patients showed lower down-phase velocity than controls.Conclusions: Patients with Graves' UER show reduced blinks rates and abnormal blink kinematics, which might be related to the development of exposure keratitis in this disease.

Fresh-cut fruit products, including carambola (Averrhoa carambola L.), have limited marketability due to cut surface browning attributed to phenolic compound oxidation by enzymes, such as polyphenol oxidase (PPO). The objective of this study was to evaluate postharvest changes in carambola slices in three different packages. Carambola fruit (cv. Fwang Tung) were picked from the Estacao Experimental de Citricultura de Bebedouro orchard at the mature-green stage. The fruit were washed, dipped in NaOCl solution (200 mg L-1 for 5 min), stored overnight at 10 degrees C, then manually sliced into pieces of approximately 1 cm. The slices were rinsed with NaOCl solution at 20 mg L-1, drained for 3 min, and packaged in polyethylene terephthalate (PET) trays (Neoform (R) N94); polystyrene trays covered with PVC 0.017 turn (Vitafilm (R), Goodyear); and vacuum seated polyolefin bags (PLO, Cryovac (R) PD900). The packages were stored at 6.8 degrees C and 90% RH for 12 d, with samples taken every 4 d. PET trays and PVC film did not significantly modify the internal atmosphere and the high water permeability of PVC led to more rapid slice desiccation. PPO activity was lower when the slices were packaged in PLO vacuum sealed bags, which reduced degreening and led to better appearance maintenance for up to 12 d. (R) 2006 Elsevier B.V.

Fresh-cut slices from ripe 'Kensington' mango (Mangifera indica L.) were prepared aseptically and stored under various treatments at 3 degrees C. Treatments included reduced oxygen (2.5%), enhanced carbon dioxide (5-40%), organic acid application, calcium chloride application, and combinations of the above. Symptoms limiting shelf-life were characterised by tissue darkening, development of a 'glassy' appearance, surface desiccation, and loss of firmness. Reduced oxygen (2.5%) was effective at controlling tissue darkening and the development of a 'glassy' appearance, while calcium application (3%) was partly effective at controlling darkening. Calcium chloride however significantly slowed (but did not stop) loss of tissue firmness. Carbon dioxide (5-40%) and citric acid had little positive effect on shelf-life, with both treatments appearing to promote tissue softening. A combination of low oxygen and calcium allowed 'Kensington' slices to be held for at least 15 days at 3 degrees C. (C) 2006 Elsevier B.V All rights reserved.

This study aimed to evaluate the postharvest conservation of tangerines 'Fremont', 'Satsuma Okitsu' and 'Ponkan' when stored at different conditions, as well as the quality of the minimally processed product. Fruit were harvested when a sugar: acid ratio of 10.0 to 12.0 for 'S. Okitsu' and 'Fremont' and 16.0 to 19.0 for 'Ponkan' was reached, selected for uniformity of color, size, and absence of injuries. Whole fruits were stored at 3 degrees C, 85% RH and 7 degrees C, 95% RH, and after each storage period, fruits were brought to ambient conditions (22 degrees C, 65% RH) for 3 days before evaluation. The minimally processed products (peeled) were packed in polystyrene trays (22.4x14.8x3.7 cm) coated with polyvinyl chloride (PVC) stretchable, with 0.014 mm thickness, and in lidded packages (500 ml) of transparent polyethylene terephthalate. Fruit were analyzed for appearance, weight loss, respiratory rate, package atmosphere, rind and pulp color, soluble solids, titratable acidity and ascorbic acid content. Shelf life of tangerine 'Fremont' was limited to 42 days based on freshness. Its minimally processed product had a 9 day shelf-life for products packaged in PVC film. The mandarins 'S. Okitsu' had 35 days shelf-life at 7 degrees C, which was reduced to 28 days at 3 degrees C. Its fresh-cut product had a shelf-life of 15 days, stored in PVC or PET. 'Ponkan' fruit stored at 3 degrees C had a shelf life of 35 days, which was reduced to 28 days at 7 degrees C. When minimally processed, its shelf-life lasted for 15 days, whether packaged in PVC or PET. The 'Ponkan' had a shelf-life of 35 days at 3 degrees C and 28 days at 7 degrees C, also limited by loss of freshness. When minimally processed and stored in PVC or PET, its shelf life reached 15 days.

The present work studied the influence of thermal treatment in oxygen rich atmosphere on heterogenous junctions in Mn-doped SnO2 polycrystalline system presenting varistor behavior. The samples were prepared by conventional oxide mixture methodology, and were submitted to heat treatment in oxygen rich atmosphere at 900 degrees C for 2h. The samples were characterized by X-ray diffraction, scanning electron microscopy, dc and ac electrical measurements. The results showed that there is an evident relationship between the microstructure heterogeneity and non-ohmic electrical properties. It was found that for this SnO2 center dot MnO-based varistor system the heat treatment in oxygen rich atmosphere does not necessarily increase the varistors properties, which was related to the decrease in the grain boundary resistance. The results are compared with Co-doped SnO2 varistors and ZnO based varistors. (C) 2008 WILEY-VCH Verlay GmbH & Co. KGaA, Weinheim.
