Abstract:

Aquatic arthropods communities were examined with respect to factors determining species distributions and community structure in a series of eight lakes on the Chilcotin Plateau of British Columbia. Climate, altitude, physical location, water temperature and basin shape were similar for all lakes, and although size differed, no evidence was found for the influence of basin morphology on community structure. Salinity and vegetation characteristics differed widely among lakes, so three major processes were investigated: the association of (1) salinity with faunal communities, (2) salinity with floral communities, and (3) faunal with floral communities. These relationships were examined in light of diversity-stability hypotheses. The severity component of environmental stability was represented by salinity, and mean surface water conductivity ranged from 56 to 13115 μS cm-¹ at 25 °C. Salinity variations among lakes were determined primarily by the ions Na, HCO₃, CO₃, C1 and K. Two classification schemes (taxonomic and ecological) and several analytical techniques (community parameters and cluster analysis) indicated that the distribution and structure of faunal and floral communities were related to salinity. In total, 84 arthropod taxa and 26 macrophyte species were found and divided into three groups: those characteristic of high salinities (>5000 μS), of moderate or low salinities (<5000 μS), or tolerant of all salinities. Faunal assemblages in all lakes were dominated by filter feeders, and predators were more abundant in saline lakes. Shredders, collectors and predators were found in all the lakes, but saline lakes had fewer size groups. Floating leaved macrophytes occurred only in freshwater lakes, submerged forms were rare in highly saline lakes, and emergent forms were found in all lakes, although they were less abundant at high salinities. Generally, this study supports the hypothesis that saline habitats have less diverse communities than freshwater ones. In all floral and faunal sample sets, increased salinity was accompanied by a decrease in species richness. Virtually all measures of macrophyte community diversity and productivity were inversely correlated with salinity. Faunal subgroups must be examined separately when measures of community structure incorporate relative abundances. Patterns of association observed in the entire faunal community were dictated by the numerically dominant entomostracan subcommunity, and patterns in other subgroups were masked. Zooplankton trophic level diversity increased with decreasing salinity and changes in community composition were analogous to those of eutrophication. In both coleopteran and hemipteran communities, diversity decreased and density increased with increasing salinity. Possible causal mechanisms structuring each community are hypothesized. Faunal distributions corresponded to their known habitat preferences in terms of macrophyte communities. It was difficult to distinguish between the influence of salinity or macrophyte communities on animal communities as animal communities were often associated with both.

Abstract:

Incorporating improved preparation techniques, modern taxonomy, and quantitative analysis of environmental variables known to influence marsh foraminifers in other coastal regions refined marsh foraminiferal biofacies of the Mississippi delta region. Elevation, pore water salinity, total carbon, and mean grain size were compared with foraminiferal distributions in a transgressive marsh system of the lower Lafourche headland of the south-central delta plain. Cluster analysis aided definition of two biofacies, one from the marsh interior and one from the marsh edge. The marsh edge biofacies was further subdivided into levee crest and bayou margin biofacies. Correlation analysis suggested that seven of the 21 most common foraminifers correlated significantly with physical variables. Juvenile Trochammina inflata correlated with salinity; Ammotium crassus and Ammonia parkinsoniana correlated with elevation; Polysaccammina ipohalina and Miliammina fusca correlated with grain size; and Miliammina fusca correlated with organic carbon. The trends are consistent with relationships observed in many other coastal regions.

Abstract:

Les evaporites Triàsiques del Keuper han estat reconegudes des de fa temps com el principal nivell de desenganxament de plecs i encavalcaments a les conques d’avantpaís pirinenques. La deformació de les conques entre el Cretaci superior i l’Oligocè mostra evidències de diapirisme, poc estudiat degut a l’empremta més visible que deixen els encavalcaments i plecs de falla. Aquesta tesi presenta un estudi multidisciplinari en el que s’explora el rol de la tectònica salina en el desenvolupament estructural i dels sistemes sedimentaris de la unitat Sudpirinenca central. El treball està centrat en dues zones d’estudi clàssiques dels Pirineus sud, com son 1) el Montsec i les Serres Marginals, i 2) el marge nord de la conca d’Organyà en contacte amb la zona de les Nogueres. Posar en valor el paper de l’halocinesi durant l’orogènia proporciona noves interpretacions amb fortes implicacions per a l’evolució cinemàtica de la compressió i la quantitat d’escurçament orogènic. A les Serres Marginals estructures salines primerenques evolucionaren durant l’etapa precompressiva mesozoica cap a un sistema de diapirs, anticlinals salins i sinclinals. Durant la compressió, els mecanismes de plegament van passar de moviments verticals produïts per la càrrega sedimentaria (bending) a plegament per buckling produït per esforços horitzontals. L’erosió de les crestes de les estructures va dur a l’expulsió de la sal i l’evolució de les estructures salines en encavalcaments. Al marge nord de la conca d’Organyà, durant l’Eocè i Oligocè la migració salina va causar el progressiu cabussament cap al nord de la conca, resultant en l’onlap i la discordança progressiva dels conglomerats de la Pobla i Gurp. Al mateix temps, la migració salina accelerada pel pes de la càrrega sedimentaria va permetre la rotació i enfonsament de les làmines desarrelades de les Nogueres en les evaporites del Keuper. A partir dels estudis de camp i la modelització numèrica, aquesta tesi explora qüestions essencials de la tectònica salina respecte la transició del plegament induït per càrrega sedimentaria al plegament degut als esforços compressius, el rol de la sedimentació i l’erosió sinorogèniques o l’efecte d’estructures diapíriques preexistents en les geometries de deformació dels avantpaïsos.
Las evaporitas triásicas del Keuper han sido reconocidas desde hace tiempo como el principal nivel de despegue de pliegues y cabalgamientos en las cuencas de antepaís pirenaicas. La deformación de las cuencas entre el Cretácico Superior y el Oligoceno muestra evidencias de diapirismo, poco estudiadas debido a la huella más visible dejada por los cabalgamientos y pliegues de falla. Esta tesis presenta un estudio multidisciplinar en el que se explora el rola de la tectónica salina en el desarrollo estructural y de los sistemas sedimentarios de la unidad Surpirenaica central. El trabajo está centrado en dos zonas de estudio clásicas de los Pirineos sur como son 1) el Montsec y las Sierras Marginales, y 2) el margen norte de la cuenca de Organyà en contacto con la zona de las Nogueres. Poner en valor el papel de la halocinesis durante la orogenia proporciona nuevas interpretaciones con fuertes implicaciones para la evolución cinemática de la compresión y la cantidad de acortamiento orogénico. En las Sierras Marginales estructuras salinas tempranas evolucionaron durante la etapa precompresiva mesozoica hacia un sistema de diapiros, anticlinales salinos y sinclinales. Durante la compresión, los mecanismos de plegamiento pasaron de movimientos verticales producidos por la carga sedimentaria (bending) a plegamiento por buckling producido por esfuerzos horizontales. La erosión de las crestas de las estructuras dio lugar a la expulsión de la sal y la evolución de las estructuras salinas en cabalgamientos. En el margen norte de la cuenca de Organyà, durante el Eoceno y el Oligoceno la migración salina causó el progresivo buzamiento hacia el norte de la cuenca, resultando en el onlap y la discordancia progresiva de los conglomerados de La Pobla y Gurp. Al mismo tiempo, la migración salina acelerada por el peso de la carga sedimentaria permitió la rotación y hundimiento de las láminas desraizadas de las Nogueres en las evaporitas del Keuper. A partir de los estudios de campo y la modelización numérica, esta tesis explora cuestiones esenciales de la tectónica salina respecto a la transición del plegamiento inducido por carga sedimentaria al plegamiento debido a los esfuerzos compresivos, el rol de la sedimentación i erosión sinorogenicas o el efecto de estructures diapíricas preexistentes en las geometrías de la deformación de los antepaíses.
The Triassic Keuper evaporites have long been recognized as the main detachment level of the Pyrenean foreland thrust belts and basins. The Cretaceous to Oligocene deformation of the forelands presents evidences of diapirism, comparatively less studied due to the most visible imprint of thrust and fault-related folds. This thesis presents a multidisciplinary study that explores the role of salt in the tectonic style of two classical areas of the southern Pyrenees, as are 1) the Montsec and Serres Marginals, and 2) the northern margin of the Organyà basin and the adjacent Nogueres Zone. The study which emphasizes the role of halokinesis in the structural and sedimentary evolution of the central-southern Pyrenees. Addressing the role of salt diapirism during the orogeny provides new interpretations with strong implications for the kinematics of compressional deformation and the amount of orogenic shortening. In the Serres Marginals, early salt structures developed during the Mesozoic pre-compressional stage into a system of diapirs, anticlines and intervening synclines that were filled. During the Pyrenean compressive stage, the folding mechanisms evolved from predominantly vertical (bending) movements triggered by the sedimentary loading to buckling by horizontal forces. The unroofing of the crests of the structure enhanced salt withdrawal, leading to primary and secondary welding and subsequent syncline imbrication. In the north margin of the Organyà basin, salt migration enabled the northward tilting of the basin during the Eocene and Oligocene, which is reflected in the progressive unconformity and onlap of the La Pobla and Gurp intramontane basins. At the same time, sedimentary load accelerated salt migration, enabling the rotation and overturning of the unrooted leading edge of the Nogueres thrust sheet (têtes plongeantes) into the Keuper evaporites. From the field case studies and numerical modelling, this thesis explores essential questions on salt tectonics, regarding the transition from load-induced bending to compressional buckling, the role of syn-compressional sedimentation and erosion or the effect of pre-existing diapir structures in the structural development of foreland basins.

Abstract:

Malawi is pursuing democratic decentralisation with duo objectives to enhance democracy at the local level and to promote poverty reduction. These reforms are largely driven by bilateral and multilateral development agencies as part of the good governance agenda, which is polluted with varying interests. This thesis argues that while in principle democratic decentralisation is desirable the pre-requisites for making it work are absent in Malawi. To a certain extent this is due to the nature of the Malawi state, which conforms to the logic of the African neopatrimonial state with unique characteristics such as personalisation and concentration of power in the dominant patron, dominance of vertical over horizontal ties, and weak separation of public and private spheres. Democratic decentralisation threatens ruling elites by promising to create spaces at the local level where the opposition can thrive. As a result reforms are characterised by centralisation as the ruling elites try to protect power and access to state resources. These characteristics can be traced back to the colonial regime and the one party state both of which were heavily centralised. At the local level chiefs, and members of parliament with ruling party connections have captured reforms and are influential in the allocation of resources. In exchange for privileges and status these actors are increasingly being co-opted by the centre to extend its control of the local arena. The result is the superficial implementation of reforms, which may further entrench neopatrimonial characteristics of the state. In the absence of strong downward accountability development agencies can play a key role to push government towards reforms. Yet local and central interests make this an uphill task. This explains the partial implementation of reforms in Malawi.

Full text

Abstract:

Salt water is produced from the Ferron Sandstone Member of the Mancos Shale in central Utah as part of the production of coalbed methane (CBM) and is disposed of by injection predominantly into the Navajo Sandstone between 4,500 feet to 7,300 feet and is considered to be a hazardous waste. Local government agencies are concerned about the potential impacts on shallow groundwater because of this disposal method. Water samples were gathered from four shallow water-supply wells, and nine salt water disposal (SWD) wells to compare hydrochemistries as an indicator of potential mixing. Shallow water-supply wells are likely recharged by local precipitation while the source of CO2 is from atmospheric and/or soil CO2 gas and comparatively, are low in total dissolved solids. Carbonate mineral dissolution is the source of CO2 in the SWD wells and is exceptionally high in TDS. The SWD water appears to be old water and displays an evaporative signature. A geologic analysis was conducted for the Drunkards Wash gas field using 479 digital gas well logs. Three subsurface faults were identified with one fault in the north and the other two in the central part of the gas field near the eastern and western flanks. These faults were further confirmed by comparing average monthly gas and water production from the first 24 months in these faulted areas to adjacent control areas. Areas near faults reveal two to six times greater gas production than that of the associated control areas, and water production is greater by nearly an order of magnitude. This difference is likely due to the fracturing associated with the damage zone near the faults allowing for increased flow of gas and water. Due to the high injection pressures the vertical hydraulic gradient has been reversed from downward to upward. However, due to the thick sequences of shale separating the disposal aquifers and the shallow aquifers the estimated time required for the disposal waters to migrate to the surface would be at least 2,000 years. I conclude that the saline waters produced from the Ferron Sandstone are being safely sequestered in deeply buried, extensive and geologically-sealed aquifers.

Abstract:

Hedonic property value analysis is one of the leading methods of environmental valuation. This non-market technique uses variation in home sales to infer the values of amenities or disamenities. While there have been numerous studies about air quality and hazardous waste, the number of papers focusing on water quality is much smaller. Consequently, there are still many unanswered questions about the proper handling of water quality through hedonic methods. Furthermore, estimates from hedonic property price analyses are rarely used in government cost benefit analyses. This dissertation investigates several important hedonic issues in a large analysis of water quality in central Florida. The first chapter of this paper explores the extent of water quality benefits. Almost all past studies have focused exclusively on waterfront homes. The present paper includes non-waterfront homes and investigates three hypotheses about the marginal impact of water quality. The first hypothesis is that non-waterfront homes are positively affected by water quality, but by a smaller amount than waterfront homes. The second hypothesis is about the effect of lake distance on the relationship between water quality and property prices: this relationship should be negative. The third hypothesis states that properties near larger lakes have a higher implicit price for water quality than homes around smaller lakes, all else constant. These three hypotheses are investigated in each chapter of the dissertation, and provide a unifying theme to the paper. Results from Chapter 1 support all three hypotheses. Most importantly, the empirical estimates indicate that water quality benefits extend beyond the waterfront in a declining gradient. Excluding non-lakefront homes from the analysis can therefore substantially underestimate the total benefits of a water quality improvement. Estimates of the total property price benefits from a one foot increase in water quality were found to double with the addition of non-waterfront homes. The second chapter examines the sensitivity of results to several spatial specifications. Spatial issues can be a problem in analyses of real estate data because of spatially correlated variables, unobservable neighborhood codes and covenants, identical or similar builders, and property appraisal valuation techniques. The focus of the chapter is on the spatial weights matrix (SWM). Six different SWM's are constructed, which are based on popular specifications encountered in the current spatial hedonic literature. An out-of-sample forecasting exercise is used to compare multiple spatial specifications. Results indicate that certain spatial models may be sensitive to the specification of the weights matrix. Furthermore, many popular models currently used in the literature could be improved by allowing more non-zero elements in the SWM. The third chapter investigates the definition of "water quality" and uses several additional quality indicators. Choosing the proper pollution indicator is an issue that has plagued many areas of the valuation literature. While clarity indicators have become popular in hedonic property price analysis, they are not used for the purposes of regulation by many state environmental departments. This chapter uses several indicators that are used by the state of Florida to classify lakes and implement policy. Implicit prices are computed for all of the indicators and issues of benefit extent and total benefits are explored. Instead of finding an optimal indicator for all situations, results indicate that the use of at least two types of indicators may capture a larger range of the true total benefits. The final chapter uses a repeat sales model to address potential problems with omitted variable bias. Due to the size of the data set in this paper, there are a substantial number of homes that have sold more than once. The repeat sales model analyzes differences in property sales prices for the same home over time. The three hypotheses of the first chapter are explored in this alternative model. The implicit price obtained from the repeat sales model is much larger than the regular hedonic model. However, there are some concerns with the smaller population of repeat sales.

Abstract:

The thesis analyses determinants of shopping centre sales and its attendance demand; it is based on data of the specific shopping centre from the years 2007 -- 2011. Based on a five-year monthly time series, two sales models are created. One model tracks sales per customer, the other deals with the shopping centre sales which are compared with the sales index of retailers. On the other hand, a model of the shopping centre attendance demand uses figures of a five-year daily time series. Independent variables with significant effect on dependent variables are identified in the theoretical part. The models are estimated using the Ordinary Least Squares estimation. In all models, seasonal influences proved to be a significant determinant. In the sales models, hypotheses of the competition effect have been verified. Furthermore, in case of the attendance demand model, weather and marketing effects were estimated as important. Surprisingly, the economic variables proved themselves to be insignificant, which could be caused by the relatively short observation period. The limiting factor of all models is also the fact that the dataset consists of one shopping centre only. It prevents the author from conducting a comprehensive examination of other important determinants of shopping centre sales and attendance.

Several anatomical and functional studies have demonstrated that the paraventricular nucleus of the hypothalamus (PVN) constitutes a neuroendocrine center. The PVN is intimately related to the regulation of the sympathetic nerve activity and vasopressin secretion. Intracerebroventricular injections of angiotensin II (ANG II), carbachol and hypertonic saline induce an increase in arterial pressure by sympathetic activation and/or vasopressin secretion. Furthermore, it was demonstrated that hypothalamic disconnection (HD) caudal to PVN, performed by way of a knife-cut into the hypothalamus using a microknife of bayonet shape, produced a decrease in basal arterial pressure, suggesting that the fibers interrupted by this HD, probably from PVN, are part of a neural circuitry responsible for tonic maintenance of the arterial pressure. Therefore, the aims of this study were to determine, in conscious rats, the effects of HD caudal to PVN (HD-C) on: a) the pressor response induced by intracerebroventricular injection of ANG II, carbachol and hypertonic saline, b) on the baroreflex and chemoreflex, c) on urinary excretion after 24 h of water deprivation. Male Holtzman rats (280-320 g) were submitted to sham-HD or acute (1 day) or chronic (15 days) HD caudal to PVN (HD-C) performed with a microknife of bayonet shape (radius = 1 mm, height = 2 mm) stereotaxically placed, positioned 1.5 mm caudal to the bregma, lowered along the midline down to the inner surface of the sphenoid and the cut as achieved by rotating it 90° left e 90° right. In sham-HD no rotation was performed. After the HD, a cannula was implanted into the lateral ventricle. Femoral vein and arterial catheters were introduced after the surgery to implant the cannula into LV (acute group) or 14 days after HD (chronic group). Rats submitted to acute HD-C did not have changes in basal mean arterial pressure (MAP), but had an increase in basal heart rate (HR), (423 ± 17 bpm) compared to sham HD rats (346 ± 8 bpm). Chronic HD did not change basal levels of MAP or HR. Baroreflex was also not changed by acute or chronic HD-C. In regard to chemoreflex, although the peak of the pressor and the bradycardic response to chemoreflex activation were not changed by acute or chronic HD-C, the duration of the pressor response was reduced in rats submitted to chronic HD-C (18±2 s) compared to sham-HD (28±3 s). The pressor response induced by intracerebroventricular (icv) injection of hypertonic saline was reduced by acute or chronic HD-C (7±3 and 21±2 mmHg vs. sham-HD: 19±4 and 36±5 mmHg, respectively). The acute or chronic HD-C also reduced the pressor response induced by icv injection of carbachol (12±3 and 21±3 mmHg vs. sham-HD: 32±4 and 35±4 mmHg, respectively) and ANG II (12±3 and 12±2 mmHg vs. sham-HD: 23±2 and 22±2 mmHg, respectively). In the 24 h water deprivation experiments, we observed a higher potassium excretion in rats with acute HD-C (DH-C: 1278±248 µEq/24 h vs sham-HD: 682±87 µEq/24 h) or chronic (DH-C: 1480±281 µEq/24 h vs sham-HD: 787±75 µEq/24 h), respectively. In chronic HD-C rats the urine volume excreted in 24 h of water deprivation was greater than the one observed in sham-HD rats (DH-C: 19±2 ml vs sham-HD: 9±0,4 ml), while the urinary volume excreted in 24 h of water deprivation in rats submitted to acute HD-C were not different from sham-HD rats. HD-C animals had polidipsia from the 6th 8th day after the HD-C, which was maintained until the last day of the experiment (14 or 17th day). These results suggest that the pressor responses induced by central injections of ANG II, carbachol and hypertonic saline, but not the baro and chemoreflex, depend on the neural pathways injured by HD-C. It is possible that the lesser pressor responses induced by central injections of these substances in HD-C rats are due to a lesser activation of sympathetic activity and/or vasopressin secretion. It is also possible that the lesser vasopressin secretion in HD-C rats is responsible for the polidipsia observed in these animals.
Diversos estudos anatômicos e funcionais têm demonstrado que o núcleo paraventricular do hipotálamo (PVH) constitui um centro de integração neuroendócrina. O PVH está intimamente relacionado com a regulação da atividade simpática e com a secreção de vasopressina. A injeção intracerebroventricular de angiotensina II, carbacol e salina hipertônica promovem um aumento da pressão arterial devido a ativação do simpático e/ou secreção de vasopressina. Ademais, foi demonstrado que a desconexão hipotalâmica (DH) caudal ao PVH, realizada por meio de um corte no encéfalo na região do hipotálamo com uma microfaca em forma de baioneta, promoveu uma redução da pressão arterial basal sugerindo que as fibras interrompidas por esta DH, provavelmente oriundas do PVH, fariam parte da circuitaria neural responsável pela manutenção tônica da pressão arterial. Portanto, os objetivos do nosso trabalho foram determinar em ratos não anestesiados os efeitos da DH caudal ao PVH (DH-C) sobre: a) a resposta pressora induzida pela injeção intracerebroventricular de angiotensina II (ANG II), carbacol e salina hipertônica (NaCl 2 M), b) o barorreflexo e quimiorreflexo; c) a excreção urinária após 24 h de privação hídrica. Ratos Holtzman (280-320 g) foram submetidos à DH-fictícia ou a DH-C aguda (1 dia) ou crônica (15 dias) que foram realizadas utilizando uma microfaca em forma de baioneta. A microfaca (raio = 2mm, altura = 3mm), adaptada no estereotáxico, foi posicionada 1,5 mm caudal ao bregma que foi introduzida no cérebro até a superfície interna do esfenóide e submetida a movimentos giratórios de 90° à esquerda e 90° à direita. Para a DH-fictícia não se realizou a rotação da microfaca. Após a DH, foi implantada uma cânula no ventrículo lateral (VL). Após a cânula no VL (grupo agudo) ou 14 dias após a DH (grupo crônico) foram inseridos cateteres na veia e artéria femoral para o registro da pressão arterial e infusão de drogas, respectivamente. Animais submetidos à DH-C aguda não tiveram alteração na pressão arterial média (PAM) basal, mas tiveram aumentos na freqüência cardíaca (FC) basal (423 ± 17 bpm) comparada com a FC basal dos ratos com DH-Fictícia (346 ± 8 bpm). A DH-C crônica não alterou os valores basais de PAM e FC. O barorreflexo também não foi alterado pela DH-C aguda ou crônica. Com relação ao quimiorreflexo, embora o pico de resposta pressora e bradicardia induzidos pela ativação do quimiorreflexo não tenham sido alterados pela DH-C aguda ou crônica, a duração da resposta pressora foi reduzida nos ratos com DH-C crônica (18±2 s) comparada com a observada nos ratos com DH-fictícia (28±3 s). A resposta pressora induzida pela injeção intracerebroventricular (ICV) de salina hipertônica foi reduzida pela DH-C aguda ou crônica (7±3 e 21±2 mmHg vs. DH-Fictícia : 19±4 e 36±5 mmHg, respectivamente). A DH-C aguda e crônica também reduziu a resposta pressora induzida pela injeção icv de carbacol (12±3 e 21±3 mmHg vs. DH-Fictícia: 32±4 e 35±4 mmHg, respectivamente) e ANG II (12±3 e 12±2 mmHg vs. DH-Fictícia: 23±2 e 22±2 mmHg, respectivamente). Nos experimentos com privação hídrica, observamos uma maior excreção de potássio em ratos com DH-C aguda (DH-C: 1278±248 µEq/24h vs DH-Fictícia: 682±87 µEq/24h) ou crônica (DH-C: 1480±281 µEq/24h vs DH-Fictícia: 787±75 µEq/24h), respectivamente. Nos ratos com DH-C crônica o volume urinário excretado em 24 h de privação hídrica foi maior do que aquele observado nos ratos com DH-Fictícia (DH-C: 19±2 ml vs DH-Fictícia: 9±0,4 ml), enquanto que o volume urinário excretado em 24 h de privação hídrica nos ratos com DH-C aguda não foi diferente dos ratos com DH-Fictícia. A excreção de sódio observada após a privação hídrica não foi diferente entre os grupos experimentais aguda ou cronicamente. Os animais com DH-C tiveram polidipsia a partir do 6º - 8º dia da DH-C, a qual perdurou até o último dia analisado (14 ou 17º dia). Nossos resultados demonstram que as respostas pressoras induzidas pelas injeções centrais de ANG II, carbacol e salina hipertônica, mas não o baro e quimiorreflexo, dependem de vias neurais interrompidas pela DH-C. Possivelmente a menor resposta pressora às injeções centrais dessas substâncias em ratos DH-C seja decorrente de uma menor ativação do sistema nervoso simpático e/ou secreção de vasopressina. É possível também que a menor secreção de vasopressina nos ratos DH-C seja responsável pela polidipsia observada nestes animais.

Alguns estudos sugerem que as vias opioidérgicas centrais parecem desempenhar um papel regulatório no controle da ingestão de água e sal em mamíferos. As ações dos opioides centrais sobre a regulação do controle hidroeletrolítico são mediadas por vários dos subtipos de receptores opioides. O papel dos receptores delta e kappa-opioides centrais neste processo não está adequadamente elucidado sendo necessário mais estudos que o esclareçam. Objetivo: Este estudo investigou o envolvimento dos receptores delta e kappa-opioides centrais no apetite por sódio em ratos depletados deste íon e em rato ativados centralmente com angiotensina. Material e Métodos: Foram utilizados ratos Wistar (270 ± 20 g), submetidos à cirurgia estereotáxica para implante de cânula guia no ventrículo lateral esquerdo (VL), no órgão subfornical (OSF), no núcleo preóptico mediano (MnPO) e no núcleo basolateral da amígdala (BLA). No protocolo de depleção de sódio os animais foram submetidos à injeção subcutânea de furosemida combinada com dieta hipossódica quatro dias após a cirurgia. Neste modelo de estudo os animais receberam injeção intracerebroventricular (i.c.v.) do antagonista delta-opioide naltrindole no quinto dia pós-cirúrgico, nas doses de 5, 10 e 20 nmol/2 μL e do antagonista kappa-opioide, norbinaltorfimina, injetado no OSF, MnPO e BLA, nas doses de 0,5, 1,0 e 2,0 nmol/0,2 μL.. O agonista específico para os receptores delta-opioides, deltorfina II (2,5, 5,0, 10 e 20 nmol/2 μL), foi injetado i.c.v. em animais depletados de sódio pré-tratados com naltrindole na dose de 20 nmol/2 μL e em animais repletos de sódio na dose de 20 nmol/2 μL. O agonista kappa-opioide, ICI199,441 (2,0 nmol/0,2 μL) foi injetado no OSF, MnPO e BLA em animais depletados de sódio pré-tratados com norbinaltorfimina 2,0 nmol/0,2 μL e em animais repletos de sódio na dose de 2,0 nmol/0,2 μL. Bebedouros de água destilada (H2Od) e de salina foram introduzidos nas caixas15 minutos após a injeção central e tiveram seus volumes monitorados nos tempos 5, 10, 15, 30, 45, 60, 90 e 120 minutos, após a colocação dos bebedouros. No protocolo de ativação angiotensinérgica central, quarto dia após a cirurgia os animais sofreram administração i.c.v. de naltrindole (5, 10 e 20 nmol/2 μL) 15 minutos antes de receberem injeções de angiotensina II na dose de 10 ng/2 μL. Os bebedouros de H2Od e de solução salina foram introduzidos nas caixas logo após a segunda injeção e tiveram seus volumes monitorados nos tempos 5, 10, 15, 30, 45, 60, 90 e 120 minutos, após a colocação dos bebedouros. Para verificar a especificidade de ação dos antagonistas opioides os animais foram submetidos aos testes de sobremesa, campo aberto e medida da pressão arterial. A análise estatística utilizada foi ANOVA modelo misto para medidas repetidas seguida do pós-teste de Bonferroni para múltiplas comparações dos volumes ingeridos e teste “t” de Student não pareado para análise dos testes de comportamento, através do programa GraphPad Prism 6.0. Resultados: Os grupos de ratos que receberam injeções i.c.v. de naltrindole após depleção de sódio e ativação angiotensinérgica central, apresentaram redução estatisticamente significante na ingestão de salina quando comparados ao grupo de animais controles. Os ratos que receberam injeção de norbinaltorfimina no OSF, MnPO e BLA após depleção de sódio apresentaram redução estatisticamente significante na ingestão de salina quando comparados ao grupo de animais controles. A estimulação dos receptores delta-opioides em animais repletos de sódio aumentou a ingestão de salina hipertônica. Conclusões: Os dados presentes sugerem que os receptores delta-opioides centrais e os receptores kappa-opioides localizados no OSF, MnPO e BLA parecem desempenhar papel fundamental na expressão do comportamento de aquisição de sal em ratos que sofreram depleção de sódio e ativação central do apetite por sódio induzido pela via angiotensinérgica.
Central opioid pathways seem to have an important role on the control of water and salt intake in mammals, and brain opioid peptides may influence hydroelectrolyte balance through a myriad of actions mediated by distinct opioid receptors. The specific role of central delta and kappa-opioid receptors (DOR and KOR) in this process is far from being fully understood. In the present work, we investigated the role of those receptors in the control of water and salt intake, in sodium-depleted rats and rats with activation central angiotensinergic. Method: Wistar male rats (250 ± 20 g) were used in the experiment after stereotaxic cannulation of the VL left, SFO, MnPO and BLA. To study the effect of the blockade of central DOR and KOR on water and salt intake in rats were sodium depleted by the concomitant use of s.c. injections of furosemide and were kept in hypossodic diet, five days after surgery. In the sixth day, they received i.c.v. injections of a selective delta-opioid receptor antagonist (naltrindole) at the doses of 5, 10 and 20 nmol/2 μL and injections in the SFO, MnPO and BLA of a selective kappa-opioid receptor antagonist (norbinaltorphimine) at the doses of 0.5, 1.0 and 2.0 nmol/0.2 μL. The specific agonist for delta-opioid receptor deltorphin II (2.5, 5.0, 10 and 20 nmol / 2 !L) was injected i.c.v. in animals depleted pretreated with sodium naltrindole at the dose 20 nmol /2 !L . The kappa-opioid agonist, ICI199,441 (2 nmol /0.2 !L) was injected into the SFO, MnPO and BLA in animals depleted pretreated with sodium norbinaltorphimine 2.0 nmol / 0.2 !L. Bottles containing water or hypertonic saline solution were introduced into the cages 15 min after the central administration. To study the effect of the blockade of central DOR and KOR on water and salt intake in animals after central angiotensinergic stimulation, the animals received intracerebroventricular injections of naltrindole at the doses of 5, 10 and 20 nmol/2 μL 30 min before receiving central injections of angiotensin II at the dose of 10 ng/2 μL. In this case, bottles containing water or hypertonic saline solution were introduced into the cages immediately after the central administration of angiotensin II. Water and salt intake were recorded for the next 2 hours after the introduction of the bottles into the cages. To verify the specificity of action of opioid antagonists animals were submitted to the dessert test, open field and measurement of blood pressure. Data were analyzed by Two-Way ANOVA mixed model followed by Bonferroni as post-hoc test. Results: The groups of rats that received i.c.v. injections naltrindole after sodium depletion and central angiotensinergic activation, showed a statistically significant reduction in salt intake when compared to control animals group. Rats receiving norbialtorphimine injection in the SFO, MnPO and BLA after sodium depletion showed a statistically significant reduction in salt intake when compared to control animals group. The stimulation of delta-opioid receptors in animals full of sodium increased intake of hypertonic saline. Conclusions: The present data suggest that the delta-opioid receptors central, and the kappa-opioid receptors located in the SFO, MnPO and BLA appear to play a key role in the expression of the salt acquisition behavior in rats with sodium appetite.

Abstract:

Os minerais são de extrema importância no metabolismo geral e no desempenho produtivo e reprodutivo dos animais a campo. Atualmente no Rio Grande do Sul, há poucos relatos sobre o diagnóstico de deficiências de minerais através da análise de macro e microelementos em fluidos biológicos. As informações disponíveis limitam-se ao diagnóstico clínico de deficiências isoladas e à análise de elementos nas pastagens, que sugerem deficiências subclínicas de alguns elementos minerais. A região da Depressão Central é caracterizada pela produção extensiva em campo nativo com manejo precário da suplementação mineral. A incidência de baixos níveis de alguns elementos nas pastagens contribuiu para a escolha da região. Os objetivos do presente trabalho foram: (a) determinar o perfil mineral em quatro períodos importantes do ciclo produtivo de matrizes (monta, repasse de touros, final da gestação e inicio da lactação); (b) diagnosticar possíveis deficiências minerais em vacas de corte na região da Depressão Central mediante a dosagem dos seguintes indicadores no sangue: Pi, Ca, Cu, Zn, glutation peroxidase (Se) e tiroxina (I). Na saliva foram dosados Na e K. (c) correlacionar os indicadores com os teores de minerais na pastagem nativa. Para isso, foram obtidas amostras de sangue e saliva em 4 propriedades no município de Cachoeira do Sul totalizando 112 animais (28 por período). O perfil indicou deficiência marginal de P, Na, I e Se em todos os períodos. As médias de Cu e Zn estiveram dentro das referências enquanto que os de K na saliva mista estiveram elevados. O Ca sérico apresentou-se diminuído embora os teores nas pastagens estivessem elevados. Foi constatada baixa correlação entre os níveis de minerais no sangue/saliva e na pastagem de todos os elementos. Os períodos mais afetados foram o final da gestação e inicio da lactação indicando que essas categorias possuem maior necessidade fisiológica.
Minerals play an important role in the metabolism and in the production and reproductive performance of animal raised on extensive grassland. Presently, in the state of Rio Grande do Sul (southern Brazil) there is a lack of information on macro and micro elements mineral deficiency troughout the analysis of biological fluids. Information available in this field reports only individual cases of mineral deficiency and analysis of elements on pastures. The level of mineral found on pasture suggests the presence of non-clinical mineral deficiency of some elements in either some seasons of the year or on the different animal categories of the State herds. The Central Valley Region, the third most important social and economically of the State cattle industry, is characterised by extensive production on natural pasture, with quite poor mineral supplementation. The low mineral level found on pastures in this area, detected by previous works, suggest further investigation. The main aims of this work were: (a) to detect possible mineral deficiency in beef cows by determining Pi, Ca, Cu, Zn, Se (gluthathion peroxidase) and I (T4) in blood and Na and K in saliva; (b) to check the possible relationships with the mineral level on pasture; (c) to detect the mineral profile on four different periods of the productive circle (IA, clean up bulls, end of gestation period and beginning of lactation). A total of seven blood and saliva samples were collected from each of four herds of Cachoeira do Sul county on four different periods. The results showed marginal deficiencies of Pi, Na, I and Se in all periods of the year. Mean values of Cu and Zn were among normal levels but the K level was above the reference level. The Ca serum level was always bellow normal and could be related to the low protein ingestion and high Mg pasture level. Finally, only a low relationship was found between mineral level on blood/saliva and pasture levels. Most critical periods were end of gestation and beginning of lactation, suggesting a relationship with the physiological need of those periods.

Abstract:

Thesis (D. Tech.(Marketing)) - Central University of Technology, Free state, 2012
A reliable sales plan and forecast is the basis for good cash flow management and capacity planning. If the sales figures are below plan, the sales manager will increase the sales efforts in order to compensate these deviations. Usually, it can be expected that these efforts should be at least partly successful in the consumer markets. This situation is expected to be different in the industrial markets, as usually the generation of sales turnover can only be achieved by either new customers or new products sold to existing customers. It is therefore expected not to be possible to immediately compensate a loss of sales turnover within the planning period by increased sales efforts. This research project investigated whether industrial markets react differently from consumer markets by investigating the sales planning and forecasting process in the Machinery & Equipment Industry, the Automotive Supplier Tier 1 and the Automotive Supplier Tier 2 Industry. It investigated several time aspects of the sales process, displayed as customer-supplier interaction. The results of the research project showed that in fact sales processes in the investigated industry sectors have such a long duration, that it is not possible for sales managers to immediately compensate low sales figures by increased sales efforts. The sales turnover raise will come in a later period and thus simply too late for the current one. This results in the fact that the reliability of the sales forecast (for the established sales plan) is reduced, if industry characteristics and special time aspects of the sales process are not taken into consideration. These time aspects can be described best by the Market Response Time (MRT). The MRT is defined as the time lag between the start of an increase of sales efforts by the supplier (first contact) and the market response in terms of increased purchase. This is at the time when the customer starts to financially respond, with the result of a sales turnover increase at the supplier’s side. If the MRT is long, sales planning and forecasting has increased importance, because sales efforts need to be planned well in advance. For this reason response times are major elements in planning and forecasting, although it was previously not very well recognised in literature and practice. Based on a qualitative empirical study with the case study methodology, 41 case studies were undertaken within the three industry sectors. The investigated companies showed that these three industry sectors have different MRTs, such as 68 weeks in the Machinery & Equipment Industry, 138 weeks in the Automotive Supplier Tier 1, and 62 weeks in the Automotive Supplier Tier 2 Industry. These different MRTs influence the companies planning and forecasting processes in different ways. This research project qualitatively showed that if time aspects were taken into consideration in sales planning and forecasting, forecast accuracy could improve. It was furthermore indicated that an adequate sales planning approach could improve forecast accuracy as well. In a second step, it was indicated that these companies, which are aware of the time aspects, have shown a better sales performance in terms of sales force productivity, growth of productivity and market position. Concluding it can be stated that the respect of time aspects, such as MRT, may increase sales performance. The study's results have some limitations, which are the research context and the research methodology. As the project only investigated the industrial context, namely the Machinery & Equipment and the Automotive Tier 1 Supplier and Tier 2 Supplier Industry, its results can only be applicable to this context. The research methodology of this project is a qualitative one, which means that the sample size is small but deep and statistical generalisations cannot be made. Based on this, further research implications of this project are that its results may further be statistically generalised by quantitative studies. Especially the sales planning and forecasting processes in the detected clusters per industry sector should be investigated on a broad sample. Thirdly, the indicated relation between market knowledge and accuracy should be further investigated. This is because it can be estimated that the forecast accuracy is the highest if the company’s information horizon is equal to the product life cycle time of the products produced. Last of all, as there are only a few research projects done in the industrial context regarding market response models and time aspects, therefore these topics should be further investigated.

Esta pesquisa integra dados de geomorfologia, feições sedimentares, pólen, diatomáceas, isótopos, mineralogia, análises químicas e datações C-14 obtidos de testemunhos da Península de Bragança, litoral do Pará. Os dados polínicos indicam que a zona central e topograficamente mais elevada da Península de Bragança foi uma área dominada por manguezais, com ampla expansão de árvores de Avicennia, presença de diatomáceas marinhas, uma tendência de aumento de matéria orgânica sedimentar de origem estuarina e uma assembleia mineralógica formada principalmente por pirita e hematita típica de sedimentos redutores de manguezais entre >6300 e ~4900 cal anos AP. Entre 4900 e 4300 cal anos AP houve uma zona estéril, sem pólen que pode ser interpretada como um brusco desaparecimento da vegetação costeira (manguezal e pântanos salgados). Nesse intervalo ocorrem ainda espécies de diatomáceas marinhas e estuarinas, assim como um aumento na contribuição de matéria orgânica sedimentar de origem marinha e um desaparecimento de minerias tipicamente formados em ambientes redutoes. No Holoceno tardio (<4300 cal anos AP), o local de estudo foi recolonizado por ervas com árvores de Avicennia restritas às bordas da planície herbácea e uma significativa tendência de aumento da contribuição de matéria orgânica de origem terrestre (plantas C4), além da presença de resíduos de diatomáceas de água doce. A composição mineralógica é formada principalmente por minerais típicos de ambientes expostos a intensa evaporação. Nas últimas décadas existe uma tendência de migração dos manguezais por sobre superfícies mais elevadas ocupadas por ervas de metabolismos C3 e C4, assim como um aumento na contribuição de matéria orgânica de origem estuarina e uma tendência de incremento nas concentrações de Sr na superfície (últimos 10 cm). Tais dados sugerem fortemente uma dinâmica dos manguezais e pântanos salgados controlados principalmente pela variação do nível relativo do mar. Provavelmente, o aumento do nível relativo do mar pós-glacial contribuiu significativamente para a implantação e expansão dos manguezais na Península de Bragança com grande impacto na expansão de árvores de Avicennia, diatomáceas marinhas/estuarinas, aumento na contribuição de matéria orgânica de origem estuarina e favorecimento de ambientes adequados para a precipitação por exemplo de pirita. Entre 4900 e 4300 cal anos AP, provavelmente o nível relativo do mar continuou aumentando. Isso causou um aumento na contribuição de espécies de diatomáceas marinhas/estuarinas e matéria orgânica de origem marinha, porém o contínuo aumento do nível relativo do mar na área de estudo afogou os manguezais e vegetações associadas, causando o desaparecimento desses pântanos do local de estudo, e, consequentemente, desfavorecimento das condições de anoxia do substrato que inviabilizou a precipitação de minerais formados por S e Fe. Após 4300 anos, houve um aumento na contribuição de matéria orgânica de origem de plantas C4 terrestre, assim como a presença de fragmentos de diatomáceas de água doce. A composição mineralógica sugere um ambiente árido tipo sabkha. Tais dados sugerem uma diminuição no nível relativo do mar que causou a recolonização por ervas de metabolismos principalmente C4 com presença de árvores de Avicennia apenas nos setores topograficamente mais baixos da planície herbácea. Considerando as últimas décadas, a migração das árvores de Avicennia em direção aos campos herbáceos, assim como a tendência de aumento de matéria orgânica de origem estuarina e nas concentrações de Sr para o topo do testemunho analisado sugerem um aumento no nível relativo do mar.
This work integrates data from geomorphology, sedimentary features, pollen, diatom, isotopes, mineralogy, chemical analysis and C-14 datings obtained of sediment cores sampled from Bragança Península, Pará littoral. The pollen data indicate that central and topographically higher area of Bragança Peninsula was an area dominated by mangroves, with wide expansion of Avicennia trees, marine diatom, an increased trend of sedimentary organic matter sourced from estuarine algae, and a mineralogical composition mainly formed by pyrite and hematite, typical of mangrove anoxic sediments between > 6300 and 4900 cal yr BP. Between 4900 and 4300 cal yr BP occurrs a without pollen zone, but along this interval takes place marine diatom, an increase of sedimentary organic matter sourced from marine algae and the absence of minerals formed by Fe and S. In the late Holocene (<4300 cal yr BP), the study site was recolonised mainly by herbs with Avicennia trees restricted to border of the herbaceous plain, presence of freshwater diatom remains and a significant increase trend in contribution of sedimentary organic matter of terrestrial origin (C4 plants). Precipitated minerals from enviroments under intense evaporation form the mineralogical composition. In recent decades, there is a mangrove migration to elevated surfaces occupied by herbs (C4 and C3 terrestrial plants), and an increase of sedimentary organic matter sourced from estuarine algae. An upward increase in the Sr concentration occurs along the last 10 cm. These data suggest a mangrove and salt marshes dynamic mainly controlled by the relative sea level changes. Probably, postglacial sea level rise contributed to the establishment and expansion of mangroves in the Bragança Peninsula with great impact on the expansion of Avicennia trees and marine diatoms, an increase of sedimentary organic matter sourced from estuarine algae. This environment favors the mineral precipitation for instance of pyrite. Between 4900 nd 4300 cal yrs BP, the continuous relative sea level rise causes the increase of marine/estuarine diatoms and the contribution of sedimentary organic matter sourced from marine algae. However, it caused the drowning of mangrove and associated vegetation, and consequently its disappearance from the study area, as well as the environmental conditions for sulfides precipitation. After 4300 cal yrs BP, the increase of sedimentary organic matter sourced from C4 terrestrial plants and freshwater diatoms suggest a relative sea level fall. The mineralogical composition suggests an arid environment, such as a sabkha. This process caused the recolonization of herbs (mainly C4 plants) in the topographically highest area of studied peninsula and Avicennia trees surrounding this herbaceous plain. Considering the last decades, the Avicennia trees migration to elevated herbaceous fields, the increase trend of organic matter sourced from estuarine algae and the increase in concentration of Sr during the last 10 cm suggest a modern relative sea level rise.

Abstract:

O Centro de Estudos de Línguas (CEL) é um projeto da Secretaria da Educação do governo do estado de São Paulo que oferece aos alunos da rede estadual e, em alguns casos da rede municipal, cursos gratuitos de línguas estrangeiras. Devido à evasão de alunos e ao baixo número de matrículas em alguns idiomas, a cada estágio as turmas ficam menores, exigindo a formação de salas multisseriadas para garantir ao estudante a continuação e a conclusão do curso. As classes multisseriadas dos CEL são compostas por discentes de várias idades e que possuem diferentes níveis de conhecimento da língua estrangeira. Nossa pesquisa tem como objetivo analisar as estratégias de ensino que os professores de língua italiana dos CEL utilizam para ensinar nas turmas multisseriadas. Fomos orientados pela hipótese de que os professores do CEL empregariam estratégias de ensino iguais ou parecidas às aplicadas pelos docentes que lecionam no ensino multisseriado da zona rural. Para a realização desta pesquisa, fizemos uma revisão sobre o funcionamento dos CEL, sobre as salas multisseriadas do campo e sobre as estratégias de ensino adotadas no contexto multisseriado e em aulas de línguas estrangeiras. Com o propósito de alcançar o nosso objetivo, adotamos a metodologia qualitativa e escolhemos o questionário on-line e a entrevista individual, semiestruturada como técnicas de coleta de dados. As participantes do estudo são professoras de italiano de grupos multisseriados de Centros de Estudos de Línguas da capital e da Grande São Paulo. Cruzamos os dados obtidos pelas duas técnicas e analisamos as três estratégias de ensino mais presentes no discurso das professoras. Comprovamos que as docentes usam estratégias que também podem ser verificadas na zona rural, ou seja, organização dos espaços físico e social, administração do tempo e emprego dos materiais didáticos. O espaço social é mais valorizado que o físico, o que conta é o aprimoramento da aprendizagem e a interação entre os estudantes de estágios diferentes. O tempo é administrado muitas vezes de forma inconsciente, mas está sempre presente na organização do atendimento dos diferentes estágios. O livro didático é essencial, todavia há um empenho em criar outras atividades empregando vários tipos de materiais. A análise nos mostrou que a maioria das professoras decidiu ensinar com os grupos organizados de maneira multisseriada. Na ausência de uma orientação pedagógica específica e do reconhecimento do Estado, as docentes, por meio da prática, criam a forma própria de lecionar, esforçam-se em adequar estratégias de ensino para cada turma.
The Language Study Center (LSC) is a governmental project of the Education Secretariat of the São Paulo State that offers for the students from state and, in some cases from the municipal, free courses in foreign languages. Due to the evasion students and low number of enrollments in some languages, each stage classes are smaller, requiring the formation of multigrade classrooms to ensure students the continuation and completion of the course. The multigrade classes of LSC are composed of students of different ages and have different levels of knowledge of a foreign language. Our research aims to analyze the use of instructional strategies to teach by the italian teachers in multigrade classes of LSC. We were guided by the assumption that LSC teachers employ teaching strategies in the same way or similar to those applied by the teachers who teach in multigrade teaching the countryside. For this research, we have made a review of the functioning of multigrade classrooms and the teaching strategies adopted for foreign language classes in multigrade context. In order to achieve our goal, we adopted a qualitative methodology choosing the online questionnaire and individual interviews, semi-structured as data collection techniques and well. Study participants are italian teachers of multigrade classes from São Paulo Language Study Centers. We crossed the data obtained by the two techniques and analyze the three instructional strategies more present in the discourse of teachers. We have proved that the teachers use strategies that can also be checked in the countryside, that is, related to physical and social space, time and materials. The social space is more valued than the physical, what counts is the improvement of learning and interaction among students of different stages. Time is administered often unconsciously, but is always present in the organization of care of the different stages. The textbook is essential, but there is a commitment to create other activities using various materials. The analysis has shown that most teachers decided to teach in organized groups multisseriate way. In the absence of a specific tutoring and state recognition, the teachers, through practice, create their own way of teaching, strive to adapt instructional strategies for each class.

Mestrado em Ensino do 1º e 2º Ciclo do Ensino Básico
O presente estudo, elaborado a partir de um projeto de intervenção realizado numa Sala de Estudo, teve como objetivo compreender a importância das Salas de Estudo no desenvolvimento plurilingue e na sensibilização à diversidade línguistíca dos seus alunos do 2.º Ciclo. Para tal, teve-se como ponto de partida o facto que a diversidade linguística e cultural, cada vez mais presente, na sociedade, motiva os alunos para desenvolverem a sua competência plurilingue. No entanto, pouco tem sido feito nas escolas para o desenvolvimento desta competência. Posto isto torna-se fulcral ir em busca de outros contextos onde haja liberdade e tempo para que as crianças desenvolvam o seu plurilinguismo. É nesta lógica que surgem, no presente estudo, as Salas de Estudo, potenciadoras das atitudes e valores das crianças, nomeadamente no que concerne à diversidade linguística e cultural. Posto isto, a presente investigação é do tipo investigação ação e nela foram utilizados, como instrumentos de recolha, notas de campo, fotografias, o inquérito por questionário e fichas realizadas com os alunos. No presente estudo verifica-se que as salas de estudo são locais onde se pode e deve ser trabalhada a educação plurilingue e a sensibilização à diversidade linguística
The present report was elaborated by an intervention project that was made in a Study Room, and it was aimed to understand the study room’s importance in the students’ Plurilingual development and at his student’s language awareness. For such, it was had as starting point the fact that the language and cultural diversity, constantly increasing in our society, motivates the students to develop their plurilingual competence. However, not much has been done at the schools for this competence development. Whereupon it is crucial to go search for other contexts where there is freedom and time for children to develop their plurilingualism. It is in this logical that arise, in the present study, the study rooms, that potentiate the attitudes and values of children, especially in what concerns to language awareness. Therefore, the present investigation is of action research type and it was used collection instrumentsm, notebooks, photgraphs, the quationaire survey and recors made by the students. In the present study it is verified that the study rooms are places where should be worked the plurilingual education and the language awareness.

Full text

Abstract:

The aim of this thesis is to break new ground by investigating the interactional organisation of real events that comprise live business-to-business cold calls. Despite being a ubiquitous part of everyday life, we know very little about how cold calls are initiated, progressed, and completed. Cold calls are unsolicited telephone encounters, initiated by salespeople aiming to get prospective clients ( prospects ) interested in their services, with the distal goal of turning them into clients and the proximal goal of getting them to agree to an initial meeting. Cold calls are often treated as a nuisance by call-takers, and salespeople must deal with reluctant gatekeepers, recurrent sales resistance, and the occasional hang-up. The training they receive often draws on outdated theories of communication and is rarely supported by empirical evidence. Thus, this study not only addresses an important domain for interactional research, but also fulfils a practical necessity for empirical research that will inform sales training and improve callers and call-takers experiences. The data comprise 150 recorded calls supplied by three British companies that sell, service, and lease office equipment. The data were collected, transcribed, and analysed within an ethnomethodological framework using conversation analysis and discursive psychology. The first analytic chapter outlines the overall structural organisation of cold calling. It documents the constituent activities within the opening, the business of the call, and the closing. It identifies and describes two types of cold calls. Freezing calls are initiated by salespeople who are contacting a prospect for the very first time. Lukewarm calls feature salespeople who claim to have been in contact with the prospect s organisation in the past. The second chapter excavates the initial turns of lukewarm calls in which salespeople ask to speak to another person within the company, with whom they indicate to be acquainted. The analysis revealed that this third-party acquaintanceship was crucial for establishing the legitimacy of the switchboard request and for improving the chances of getting it granted. The third chapter focused on appointment-making sequences in both freezing and lukewarm calls, showing that they comprise two components: a preamble and a meeting request sequence. I also highlight how salespeople exploit sequential and turn-taking mechanisms to secure meetings with prospects without giving the latter the opportunity to refuse. The final chapter examines two practices for enacting resistance in cold calls blocks and stalls and documents the range of methods salespeople employ for dealing with each type of resistance. Sales blocks expose the salesperson s commercial agenda, attempt to stop the prospecting activity, and move towards call pre-closure. In response, salespeople can challenge, counter, or circumvent blocks as well as redo their initiating actions. Stalls slow down the progress of the sales process by delaying the next phase of the sale or by proposing less commitment-implicative alternatives. Salespeople deal with stalls by either justifying their initial proposal or by spontaneously introducing new action plans, both being more conducive to the progress of the sale. The thesis contributes to a growing body of interactional research on commercial encounters by shedding empirical light on a previously unexamined setting, business-to-business cold calls. It also moves forward discursive psychology s project of respecifying psychological phenomena by documenting the communicative practices associated with persuasion and resistance. Finally, it expands the extant conversation analytic toolkit by examining new practices (such as appointment-making) and by providing new insights into key conversation analytic topics (such as requests, pre-sequences, and accounts for calling). Overall, the findings presented in this thesis challenge existing conceptions of prospecting through cold calling that are prevalent in the sales literature. The thesis puts forward a strong argument for opening the black box of cold calls to better understand these interactions and to identify good practices as the basis for communication training. Research presented in this thesis has already been used in the development of CARM (Conversation Analytic Role-play Method) training for salespeople, who reported having doubled their appointment rates. Based on the findings in this thesis, I plan to develop further training not only for salespeople but also for prospective customers, thus improving the overall outcome of cold call encounters.

In this thesis I investigate social processes that motivate the contemporary reproduction and public dissemination of older Central Coast Salish spindle whorls. In a case study, I develop a cultural biography of spindle whorls to examine how material culture produced by past generations informs contemporary activity. Visual materials, first- and third-person accounts and writings in three areas—material culture, the social nature of art and colonialism—are drawn together to demonstrate that spindle whorl production and circulation is grounded in social and historical contingencies specific to Central Coast Salish First Nations. I propose that in using spindle whorls, Central Coast Salish people are drawing on the past to strengthen their position within current circumstances.

Abstract:

Intra-archipelago waterways, including tidal strait networks, present a complex set of barriers to, and conduits for sediment transport between marine basins. Tidal straits may also be the least well understood tide-dominated sedimentary environment. To address these issues, currents, sediment transport pathways, and seabed sedimentology & geomorphology were studied in the central Salish Sea (Gulf and San Juan Islands region) of British Columbia, Canada and Washington State, USA. A variety of data types were integrated: 3D & 2D tidal models, multibeam bathymetry & backscatter, seabed video, grab samples, cores and seismic reflection. This dissertation included the first regional sediment transport modelling study of the central Salish Sea. Lagrangian particle dispersal simulations were driven by 2D tidal hydrodynamics (~59-days). It was found that flood-tide dominance through narrow intra-archipelago connecting straits resulted in the transfer of sediment into the inland Strait of Georgia, an apparent sediment sink. The formative/maintenance processes at a variety of seabed landforms, including a banner bank with giant dunes, were explained with modelled tides and sediment transport. Deglacial history and modern lateral sedimentological and morphological transitions were also considered. Based on this modern environment, adjustments to the tidal strait facies model were identified. In addition, erosion and deposition patterns across the banner bank (dune complex) were monitored with 8-repeat multibeam sonar surveys (~10 years). With these data, spatially variable bathymetric change detection techniques were explored: A) a cell-by-cell probabilistic depth uncertainty-based threshold (t-test); and B) coherent clusters of change pixels identified with the local Moran's Ii spatial autocorrelation statistic. Uncertainty about volumetric change is a considerable challenge in seabed change research, compared to terrestrial studies. Consideration of volumetric change confidence intervals tempers interpretations and communicates metadata. Techniques A & B may both be used to restrict volumetric change calculations in area, to exclude low relative bathymetric change signal areas.

Abstract:

This thesis conducted the first acoustic analysis on Lekwungen (aka Songhees, Songish) (Central Salish). It studied the acoustic correlates of stress on vowels and the effects of consonantal coarticulatory effects on vowel quality. The goals of the thesis were to provide useful and usable materials and information to Lekwungen language revitalisation efforts and to provide an acoustic study of Lekwungen vowels to expand knowledge of Salishan languages and linguistics. Duration, mean pitch, and mean amplitude were measured on vowels in various stress environments. Findings showed that there is a three-way contrast between vowels in terms of duration and only a two-way contrast in terms of pitch and amplitude. F1, F2, and F3 were measured at vowel onset (5%), midpoint (50%), and offset (95%), as well as a mean (5%-95%), in CVC sequences for four vowels: /i/, /e/, /a/, and /ə/. Out of five places of articulation of consonants in Lekwungen (alveolar, palatal, labio-velar, uvular, glottal), uvular and glottal had the most persistent effects on F1, F2, and F3 of all vowels. Of the vowels, unstressed /ə/ was the most persistently affected by all consonants. Several effects on perception were also preliminarily documented, but future work is needed to see how persistence in acoustic effects is correlated with perception. This thesis provides information and useful tips to help learners and teachers in writing and perceiving Lekwungen and for learners learning Lekwungen pronunciation, as a part of language revitalisation efforts. It also contributes to the growing body of acoustic phonetic work on Salishan languages, especially on vowels.

Full text

Abstract:

The Coast Salish subsistence economy has been characterized by local fishing adaptations to regional ecological variability (Mitchell 1971a.) This dissertation explores the temporal depth of these adaptations in the traditional territory of the Coast Salish, the Gulf of Georgia. Many researchers have used this, Donald Mitchell’s (1971a), model to develop theories of regional cultural development. Many of these interpretations present social complexity or social inequality – a hallmark of Northwest Coast social complexity – as having developed more or less in lock-step with the specialized fishing adaptation described among the Central Coast Salish, around the Fraser River. The temporal depth of this adaptation and the “Diversified” fishing adaptations described among the Northern and Southern Coast Salish, as well as their developmental relationship, are not well understood. In exploring this problem, this study evaluates whether or not the ecological ethnographic model is representative of the archaeology of these cultural subareas. A gap in the regional dataset which corresponds with a large portion of Mitchell’s (1971a) “Northern Diversified” fishing subarea has largely presented a previous study of this type. Recently excavated sites in traditional shíshálh territory provide artifact and archaeofaunal data that fill in this gap. These data are analyzed along with existing data from the Northern subarea and from the Central Gulf of Georgia (River and Straits Fishing subareas). The results of this study significantly broaden our understanding of prehistoric Coast Salish socioeconomic diversity, and test the assumed salmon specialization on the Fraser River and its primacy the development of regional ethnographic characteristics, especially pronounced social inequality. The results also shed light on the prehistoric importance of herring, a decreasingly overlooked resource in Northwest Coast archaeological studies, and advocate for the use of fine mesh recovery for quantifying the relative importance of fish species.

Abstract:

This research examined the potential for protected areas with camas (including tall camas, Camassia leichtlinii (Baker) Wats., and common camas, C. quamash (Pursh) Greene; Liliaceae (Agavaceae)) habitat to support the renewal of Central Coast Salish camas traditions while at the same time maintaining and even expanding their ecological restoration and conservation goals. For many generations Central Coast Salish Peoples of northwestern North America have cultivated camas plants and harvested, processed, and consumed their edible bulbs in large quantities. Today, after camas use has almost completely disappeared from their lives, some Indigenous peoples are working to restore camas habitats and cultivation practices on southern Vancouver Island and neighbouring areas. Tall camas and common camas can still be found growing in many Garry oak ecosystems, which, due to the decreased range and the large proportion of rare species found within them, are frequently the focus of ecological restoration and conservation efforts. I interviewed people from the resource management and First Nations communities to gain an understanding of the current interests, opportunities, challenges, and potential approaches for incorporating traditionally based camas harvesting and management into protected areas today. Protected areas were identified as important areas for teaching traditional plant cultivation techniques to younger generations, and as bulb and seed banks for ethnoecological restoration projects. Overall, managers of protected areas and First Nations participants were receptive to collaborating on management of camas populations. Anticipated or existing challenges or concerns included ecological uncertainties of harvesting disturbance, ensuring safety, finding funding, and gaining trust. I conducted one season of experimental camas harvesting in a Garry oak savannah near Duncan, BC within an ecological preserve and monitored the effects of this harvesting on the extant camas populations, on surrounding plant communities, and on soil porosity. Harvesting of, primarily tall, camas bulbs, at both low and medium intensity, did not affect the weight or abundance of camas bulbs or the quantity, stem height or flowering/fruiting potential of the camas populations in the following year. Harvesting significantly reduced the abundance of Kentucky bluegrass (Poa pratensis) and common snowberry (Symphoricarpos albus, but significantly increased the abundance of Scotch broom (Cytisus scoparius) common cleavers (Galium aparine), hairy cat’s ear (Hypochaeris radicata), and nipplewort (Lapsana communis). Harvesting significantly reduced the level of soil compaction. Using the insights gained from the interviews and experimental harvesting I have proposed an “Ethnoecological Restoration Support Model”. This model explains how protected areas can support cultural restoration both within and outside of protected areas while maintaining and even expanding upon current conservation and restoration goals.

Abstract:

The reason for this story was to investigate a narrative that is important to the identity of North America’s Pacific Northwest Coast – a narrative that revolves around wild salmon, a narrative that always seemed too simple to me, a narrative that gives salmon a mythical status, and yet what does the average person know about this fish other than it floods grocery stores in fall and tastes good. How do we know this fish that supposedly defines the natural world of this place? I began my research as a science writer, inspired by John Steinbeck’s The Log from the Sea of Cortez, in which he writes that the best way to achieve reality is by combining narrative with scientific data. So I went looking for a different story from the one most people read about in popular media, a story that’s overwhelmingly about conflict: I searched for a narrative that combines the science of what we know about salmon and a story of the scientists who study the fish, either directly or indirectly. I tried to follow Steinbeck’s example and include the narrative journeys we take in understanding the world around us, the journeys that rarely make it into scientific journals. I went on about eight field trips with biology, ecology, and archaeology lab teams from the University of British Columbia and Simon Fraser University in Vancouver, with the Department of Fisheries and Oceans onboard the Canadian Coast Guard Ship the W.E. Ricker, and an archaeological crew from the Laich-Kwil-Tach Treaty Society in Campbell River, B.C. At the same time, I was reading a number of things, including a 1938 dissertation by anthropologist Homer Barnett from the University of Oregon titled The Nature and Function of the Potlatch, a 2011 book by economist Ronald Trosper at the University of Arizona, Resilience, Reciprocity and Ecological Economics, and works by psychologist Douglas Medin at Northwestern University and anthropologist Scott Atran at the University of Michigan, written over the past two decades, particular paying attention to their writings on taxonomy and folkbiology. My conclusions surprised me, a little.

The present study dealed with the natural vegetation of Beei Yu Shan, Shalishan Region in Experimental Forest of National Taiwan University, aimed on the vegetation-types and their compositions and distributions among different habitats. The population structure of major vegetation-types was analyzed to understand their regeneration status and succession. Moreover, the conservation properties of rare species in this area were evaluated. The study area is about 98 ha, ranging from 1,250m to 1,849m in altitudes and within subtropical and warm-temperate zones. 18 plots were set and investigated from September 2005 to February 2007. 97 families, 209 genera and 303 species of vascular plant were record, among which 83 species was endemic in Taiwan (27.4% of all). Two-way indicator species analysis were used and the plant communities were divided into 4 vegetation types and two subtypes, namely: 1. Pasania harlandii-Platycarya strobilacea forest type; 2. Cyclobalanopsis stenophylloides-Carpinus kawakamii forest type, including 2-1. Cyclobalanopsis stenophylloides-Carpinus kawakamii forest subtype; 2-2. Cyclobalanopsis glauca-Carpinus kawakamii forest subtype; 3. Lithocarpus castanopsisifolius-Machilus japonica forest type; 4. Cinnamomum camphora- Alnus formosana-Debregeasia orientalis forest type. Pteridophyte-coefficient（Ptph-Q） in this area was 3.69. In order to examine the relationship between vegetation and environment, five environmental factors were chosen to test their correlation with the vegetation types. Three factors, namely altitude, soil stoniness, topographic position, were found obvious correlated. The study followed the IUCN grading system and estimating standard, as well as the status of rare and endangered species consulted and cited by domestic researchers, to evaluate rarities of plant species in this area. Sequentially 24 rare and endangered species were recognized, in which 3 species cited as endangered, 9 species as vulnerable, and 12 species as rare. The result can be used as basic information of evaluating nature conservation area, academic research of forest ecology, biodiversity and recovery ecology management.

Abstract:

Waldsea, Deadmoose, and Lenore lakes are three saline lakes located in the Lenore Basin drainage complex north of the town of Humboldt in south-central Saskatchewan, Canada. Waldsea Lake and Deadmoose Lake are both meromictic, with anoxic, saline to hypersaline (~30-45 g L-1 TDS) Na-Mg-SO4 –rich monimolimnion waters underlying hyposaline to saline mixolimnions. Lenore Lake water shows similar ionic ratios but is less saline (~4 g L-1 TDS) and does not exhibit meromixis. Water levels in these closed-basin lakes have historically fluctuated dramatically. Present-day high levels in the basins have lead to considerable social, economic, and environmental disruptions and problems. Short sediment cores (~1 m length) were collected from deep-water offshore locations in each basin in order to study sedimentological and hydrological changes that have occurred over the past several millennia and to place the current high water levels into a longer-term perspective. The late Holocene stratigraphic sequences recovered from Waldsea and Deadmoose lakes are roughly similar: both comprise overall well-bedded, fine-grained, organic-rich sediment dominated by endogenic gypsum and detrital clay minerals, with associated quartz, plagioclase and carbonate minerals. They both contain laminae composed of endogenic aragonite. Two lithostratigraphic units are identified in each sequence on the basis of bedding, grain size, organic matter content, geochemistry, mineralogy, and δ18O and δ13C characteristics. Although chronostratigraphic control is limited, AMS 14C dating of plant remains in the cores indicate that the recovered sequence from Waldsea spans approximately 1500 years whereas the Deadmoose sequence covers about 3500 years. The recovered Lenore Lake sequence is mainly non-bedded and largely composed of fine to coarse-grained siliciclastics and detrital carbonate minerals. Like Waldsea and Deadmoose, two lithostratigraphic units are identified, however efforts to establish chronostratigraphic control for the section recovered from Lenore Lake were not successful. The short cores recovered from each of these basins show a clear change from shallow water deposition at the base to deep(er) water conditions further up the section. This change was likely a result of the development of a more positive hydrologic budget in each of the basins. The lack of chronological synchrony of the interpreted hydrologic changes, however, suggest that the effects of regional climatic fluctuations are masked by various intrinsic sedimentological, geochemical, and biological processes operating within each basin.

Climate change studies have pointed out that meteorological changes have both regional and seasonal differences. Previous research on the possible impacts of climate change on vegetation in Taiwan mainly focused on the changes in annual mean climatic parameters, therefore neglected the seasonal differences. In addition, using climatic envelopes derived globally to model vegetation-climate relations in Taiwan also likely obscured the small-scale vegetation and climate evolutional relationships. The main objective of this study was to develop vegetation-climate relationships based on monthly meteorology parameters for tree species in Salisen area, a mountainous region with elevation ranging from 1200 m to 3952 m, of central Taiwan. Monthly climatic parameters for the study area were first derived from long-term meteorological data using a generalized additive model (GAM) approach, with altitude and spatial coordinates as the explanatory variables. Then a modified Bioclimatic Affinity Groups (BAG) model was used to construct BAGs for three dominant plant functional types, namely, evergreen needle-leaved, evergreen broad-leaved trees, and deciduous broad-leaved trees, in the study area. Tree species distributions within the study area were based on 72 composite plots from a previous study. Using R-square value 0.7 as the threshold value, 6, 11, and 8 BAGs were derived for evergreen needle-leaved, evergreen broad-leaved, and deciduous broad-leaved trees, respectively. In this study, due to limited variations, precipitation parameters had little contribution to explain the differences among BAGs. Temperature and light sky space parameters were the main factors in delineating BAGs, especially in evergreen needle-leaved tree type. In general, temperature was the main factor in differentiating BAGs. BAGS with similar temperature requirements could be further distinguished by whole light sky space (WLS). The main difficulty encountered in this study was that some species were only present in a limited number of plots. For those species, the derived BAGs overextended their distribution ranges. The second difficulty encountered was that in a small region monthly temperature parameters were highly correlated. Despite these difficulties, the BAGs derived in this study could still be mapped directly to the main vegetation types in the study area, suggesting that the derived BAGs were in agreement with reality. The results of this study would enhance future modeling efforts on possible impacts of climate changes on the study area’s vegetation dynamics.

Abstract:

Stable carbon isotope fractionation during methanogenesis is affected by the availability of substrates. The effects of different substrates on methanogen biomass, total lipid extract, biomarkers and methane under both abundant and limiting substrate conditions were studied. Methanosarcina barkeri was grown with methanol, acetate, trimethylamine (TMA) and H2/CO2, and carbon isotope fractionation in methane production was greatest with methanol, followed by H2/CO2, TMA and acetate. In contrast, biomass was isotopically lightest in M.barkeri grown on methanol, followed by TMA, H2/CO2 and acetate. Generally, fractionation was greater in cultures grown with abundant substrate availability as compared to those supplied with limiting substrate. During autotrophic growth, fractionation was greatest during slower growth for both methane and biomass production. The results of these fractionation studies under controlled laboratory conditions can be applied to the interpretation of isotopic signatures for methane and methanogen biomarkers, and ecological processes, in marine environments. Several hypersaline springs off the western shore of Lake Winnipegosis, MB support unique microbial mat communities. These low temperature springs contain water with a mean salinity as high as 6.1%. Studies were undertaken to contrast the anaerobic microbial communities of these springs, specifically the methanogens and sulphate-reducing bacteria (SRB), and their contributions to biogeochemical cycling in these mats. Comparisons of lipid profiles revealed changes in the proportions of the dominant fatty acids related to the amount of mat growth. Cultures of SRB and methanogens were established with six different substrates. Methanogenic cultures grew best on TMA and methanol, but could use formate, H2/CO2 and glycine betaine as well. In contrast, H2/CO2 was the preferred substrate of the SRB enrichment cultures, which were also able to use formate, but not TMA, the breakdown product of the compatible solute glycine betaine. Maximum methane production occurred at 5% salinity. The lipid composition of the mats, including methanogen biomarkers, and the results of the enrichments on different substrates and at different salinities, suggest that methanogenesis in these springs is supported by compatible solutes whereas sulphate reduction is linked to availability of hydrogen and formate.

Abstract:

It is universally acknowledged that international trade and cooperation have become key drivers of SMEs. Indeed, the success of SMEs in the sales sector depends upon their capacity to conquer the foreign market and compete with larger companies. Many SMEs today, in particular those in Central and West Africa, are very much aware of this reality. However, because of differences between domestic laws and their maladjustment, many African SMEs still struggle to enter the international market and compete with larger companies. It is therefore obvious that any SMEs that want to succeed in international commerce today will be called upon to confront different regulations, whether domestic, regional or international, which are often shaped according to the realities and expectations of a particular environment. The challenge today is to regulate and harmonise these different legal systems, in order to render the law identical in numerous jurisdictions. This process of unifying the law internationally, in particular the law of sale, started in 1920 and culminated in 1988, with the implementation of the CISG. This Convention, which has become the primary law for international sales contracts, endeavours to deal with this problem of differences in law between states on a global scale, by attempting to achieve a synthesis between different legislations, such as civil law, common law, socialist law, and the law regarding industrialised and Third World countries. Even though the CISG appears to be a compromise between different legal systems, the fact remains that it is not yet applicable in many countries, especially those in Central and West Africa, which are mostly still ruled by domestic and regional law, namely the OHADA. The purpose of this study is to attempt to analyse and compare the OHADA’s Uniform Act Relating to Commercial Law to the CISG, in order to identify similarities and differences between the two, and to determine, with regard to the operating mode and structure of SMEs in West and Central Africa, which one of the two legislations is more appropriate.

Dissertação de Mestrado em Ciências da Educação, Educação Especial - Domínio Cognitivo e Motor
Uma linha de investigação sobre a inclusão que tem vindo a ganhar terreno centra-se sobre as variáveis da escola, sala de aula, e professores, na medida em que são relativamente fáceis de manipular e por isso relativamente fáceis de traduzir em mudanças na prática. O presente estudo procurou analisar através do método do questionário qual é a perceção dos professores (n = 80) dos agrupamentos de escolas de Lamego, em relação à inclusão de alunos portadores de Paralisia Cerebral. Os resultados assinalam que (80%) dos inquiridos concorda com a inclusão e que (29%) dos professores com mais de 20 anos de serviço não concorda com o apoio a alunos com NEE, portadores de Paralisia Cerebral dentro da sala de aula. Uma percentagem de professores (70%) entende que o apoio a alunos com NEE deve realizar-se em contextos inclusivos da sala de aula ao passo que (30%) dos inquiridos não concorda com o apoio aos alunos com NEE em contextos inclusivos de sala de aula. A maioria dos inquiridos (60%) entende que a inclusão na turma de alunos com NEE portadores de Paralisia Cerebral, beneficia o seu próprio sucesso escolar educativo. Existe uma percentagem de docentes (20%) que pensam que a inclusão das crianças portadoras de Paralisia Cerebral na sua turma beneficia o sucesso escolar e educativo da turma. Dos restantes inquiridos (20%) entendem que a inclusão das mesmas prejudica o sucesso escolar e educativo da turma. A perceção de aceitação em relação à integração das crianças portadoras de Paralisia Cerebral no sistema geral de ensino (76%), é influenciada pelo grau de deficiência Motora e Intelectual da criança, enquanto (24%) dos inquiridos não está sensibilizado para a inclusão destes alunos no sistema geral de ensino independentemente do grau de deficiência Motora e Intelectual que o aluno possa possuir. Na formação inicial de quase todos os professores (84%) não houve uma sensibilização a nível da problemática da inclusão de crianças com NEE, apenas (16%) dos inquiridos reconhece ter sido sensibilizado para a problemática da inclusão de crianças com NEE. No que se relaciona com as ações de formação (82%) dos inquiridos tem por hábito frequentar ações de formação, todavia (27%) dos professores é da opinião que essas acções de formação, nas quais costumam participar, não vão de encontro às suas reais necessidades. A maior dificuldade dos docentes face à inclusão de alunos com NEE, são as expectativas negativas dos professores. Nesta direção verificamos também que (43%) dos professores inquiridos não acredita que estes alunos venham a desempenhar um papel ativo na sociedade.
A line of research on inclusion that has been gaining ground focuses on the variables school, classroom, and teachers, in the extent that those variables are relatively easy to manipulate and to translate in changes in practice. This study analyzed by the method of survey, what is the perception of teachers (n = 80) of the clusters of schools in Lamego regarding the inclusion of students with cerebral palsy. The results indicate that (80%) of respondents agree with the inclusion, and that (29%) of teachers with over 20 years of service do not agree with the support of pupils with Special Needs Education (SNE) with cerebral palsy, in general education. A percentage of teachers (70%) believe that support for students with SNE should take place in inclusive classrooms while (30%) of respondents do not agree to support students with SNE in inclusive classroom. Most respondents (60%) believe that the inclusion in the classroom of pupils with SNE with cerebral palsy, benefits their success in school education. There are a percentage of teachers (20%) who think that the inclusion of children with cerebral palsy in their classes benefits the school education of the classes. The remaining inquired (20%) construe that their inclusion injure the group`s educational success. The perception of acceptance of related to the integration of children with cerebral palsy in general education (76%) is influenced by the degree of motor and intellectual disabilities of the child, while (24%) of respondents is not sensitive to the inclusion of those students in general education system regardless of the degree of motor and intellectual disabilities that the students may have. In undergraduate education of almost all teachers (84%), there was no level awareness about the issue of inclusion of children with SNE, only (16%) of respondents acknowledge that they have been sensitized to the issue of inclusion of children with SNE. With regard to training, (82%) of respondents say that they have a habit of attending training actions, however (27%) of teachers believe that those training initiatives in which they typically participate, do not meet their real needs. The main difficulty of teachers towards the inclusion of students with SNE is the negative expectations of teachers. In this sense, we also found that (43%) of teachers surveyed do not believe that those students will play an active role in society.

Abstract:

The objective of the study was to determine whether any relationships exist between personality and the performance of sales staff in a call centre environment. Personality type (measured by the Jung Type Indicator [JTI]) and sales personality type (measured by the Sales Preference Indicator [SPI]) were correlated with sales staff performance in an insurance call centre environment. A quantitative survey was conducted using a sample of N = 146. Correlational and inferential statistical analyses revealed statistically significant positive, although weak, relationships between personality type and the performance of call centre sales staff while statistically significant positive and negative correlations, although weak, were found between sales personality type and the performance of call centre sales staff. More female and black sales staff members were found in the higher performing clusters than in the average and poorer performing clusters. The best subset of personality scales from the JTI that predicted univariate measures of performance were the extroversion-introversion scale and the judging-perceiving scale while the best subset of predictors from the SPI personality scale were the consistent-adaptive scale and the cooperative-competitive scale. Call centre performance criteria are based mainly on quantitative performance criteria. It emerged from the literature review that the call centre sales position is synonymous with emotional labour and it is, thus, recommended that future research should emphasise the importance of emotionally intensive labour and its measurement combined with quantitative performance measures.
