A crónica no panorama literário cultural cabo-verdiano : da crítica social a uma preocupação humanitária : Salústio e Medina : dois casos paradigmático

Esta dissertação visou compreender o caráter temático e discursivo de algumas crónicas literárias de dois autores cabo-verdianos, Dina Salústio e Daniel Medina, e provar o carácter pedagógico e humanitário das composições. Fez-se, num primeiro momento, um estudo de conteúdos teóricos sobre a cronística portuguesa, visando recensear aspetos relacionados com a evolução do género ao longo dos tempos, desde a Idade Média até à Contemporaneidade, sempre numa perspetiva pragmática, e discutiram-se as características enformadoras do género, sendo assinaláveis a subjetividade, versatilidade, objetividade, estilo entre o oral e o literário, quotidianidade e dialogismo. De seguida, em termos metodológicos, optou-se por convocar o ethos de Amossy e Maingueneau para o estudo das composições. Num segundo momento, através de dez crónicas literárias cabo-verdianas, sendo cinco de cada autor, procedeu-se à análise crítica das quais se confirmou, a partir da análise temática, uma preocupação pedagógica e humanitária uma vez que se notou uma certa inquietação com problemas que envolvem a idiossincrasia do homem cabo-verdiano, como a perda de valores em termos educacionais e instrucionais, quer no seio familiar como escolar, a preocupação com os mais desfavorecidos materialmente, onde se destacam crianças órfãs de pais vivos, o descaso com os doentes mentais e as crianças de rua, a gravidez precoce, a prostituição infantil, entre outros. O modo, como os cronistas se posicionam face à abordagem dos temas, permitiu-nos projetar o ethos discursivo de duas personalidades sensíveis, sérias e comprometidas com os valores mais nobres que enformam o ser humano. Do mesmo modo, pôde constatar como características relevantes das composições a subjetividade e pessoalidade discursivas, a brevidade, o diálogo no estilo indirecto livre, a quotidianidade e literariedade aliados a alguns recursos retóricos que nos permitiram apurar os tons sério e irónico do sujeito enunciador ao tratar as questões temáticas.

Carte et tableau : approche épistémologique ternaire

Under the referential of a ternary logic, this article aims to focus on the geographical map perceived as a visual object and the question of surfaces of representation. We analyse the status of map making versus landscape representation, the relations between a map and a painted picture. A ternary model of the pictural composition perspective|light/pictural field is proposed. The frame of the map, articulating the space that is cut out and the space included is discussed in a parallel between maps and painted pictures.

Optimització i aprofitament del temps de pràctica motriu en les classes deducació física d'un grup de 4t ESO

Amb aquest treball d‟investigació es pretén fer veure al docent la importància d‟una adequada gestió del temps de classe d‟Educació Física (E.F.), concretament, abans, durant i al final de la sessió, amb l‟objectiu d‟augmentar el temps de compromís motor dels alumnes. Tanmateix citaré autors i esmentaré estudis que demostren que un increment en el temps de compromís motor per part de l‟alumne, augmenta la probabilitat de que s‟assoleixin els objectius proposats i, per tant, el procés d‟ensenyament – aprenentatge serà més eficaç. En conseqüència, s‟analitzen les categories i variables temporals (temps d‟informació del professor, temps d‟organització dels alumnes i del material i temps d‟imprevistos) que poden restar minuts al temps de pràctica motriu i, a la vegada, es presenten una sèrie de recursos i estratègies que ajuden al professor d‟E.F a reduir les accions i variables temporals que incideixen negativament a fi i efecte d‟augmentar el temps de pràctica motriu.

Der Baum in der Gegenwartskunst: Nachhaltigkeitsindikator

[deu]Dieser Artikel analysiert wie der Baum, hauptsächlich als lebendiges Wesen, im Bereich der zeitgenössischen Kunst verwendet wird. Der Baum wird als Objekt und als Subjekt behandelt, wird jedoch auch zum Experimentier- und Forschungsfeld der Kunst. Abgesehen von seinem Wesen als Objekt und Pflanze, erlangt er gleichzeitig als Standort eine räumliche Bedeutung. Anhand ausgewählter Beispiele wird aufgezeigt wie der Baum als weltweite Ikone sowohl auf die Zerstörung der Umwelt als auch auf die Ökologische Erhaltung und Zerstörung des Planeten in der zeitgenössischen Kunst hinweist.[eng]This paper analyses how the tree, mainly as a living being, is used in contemporary art. The tree is approached as object and subject, but also becomes a territory-space of experimentation and research. But beyond its plant and objectual character, the tree itself adopts a territorial sense as place. The diverse examples selected corroborate the use of the tree in contemporary art as a universal global icon of conservation and the environmental destruction of the planet.

Image quality assessment in digital mammography: part II. NPWE as a validated alternative for contrast detail analysis.

Assessment of image quality for digital x-ray mammography systems used in European screening programs relies mainly on contrast-detail CDMAM phantom scoring and requires the acquisition and analysis of many images in order to reduce variability in threshold detectability. Part II of this study proposes an alternative method based on the detectability index (d') calculated for a non-prewhitened model observer with an eye filter (NPWE). The detectability index was calculated from the normalized noise power spectrum and image contrast, both measured from an image of a 5 cm poly(methyl methacrylate) phantom containing a 0.2 mm thick aluminium square, and the pre-sampling modulation transfer function. This was performed as a function of air kerma at the detector for 11 different digital mammography systems. These calculated d' values were compared against threshold gold thickness (T) results measured with the CDMAM test object and against derived theoretical relationships. A simple relationship was found between T and d', as a function of detector air kerma; a linear relationship was found between d' and contrast-to-noise ratio. The values of threshold thickness used to specify acceptable performance in the European Guidelines for 0.10 and 0.25 mm diameter discs were equivalent to threshold calculated detectability indices of 1.05 and 6.30, respectively. The NPWE method is a validated alternative to CDMAM scoring for use in the image quality specification, quality control and optimization of digital x-ray systems for screening mammography.

Les marquages corporels à l'adolescence : expression d'un mal-être profond? : se marquer pour se démarquer : du repérage des signes au choix des réponses adaptées

La problématique des marquages corporels en tant que pratiques ancestrales s'insèrent dans des formes contemporaines d'inscription corporelle. Nous nous sommes permis d'essayer de savoir s'il s'agissait toujours d'une expression d'un malaise psychologique important ? Quelles peuvent en être les conséquences ? Pourquoi marquer le corps ? La mise en oeuvre de ce travail s'est articulée en deux phases, au départ, nous avons opéré par une pré-enquête d'envergure qui a regroupé 200 adolescents (10 filles et 190 garçons). Ensuite et dans un deuxième temps nous avons interrogé dix adolescents qui se marquent la peau dont trois garçons, âgés de quinze à dix-neuf ans. Grâce à une « tri approche » : Entretien clinique, tests du Rorschach et du TAT. Les résultats auxquels nous sommes parvenus peuvent être résumés comme suit : ces pratiques expriment une souffrance qui peine à trouver une voie d'expression symbolique autre que le corps, l'angoisse et la relation d'objet du type anaclitique, l'organisation défensive renseigneraient essentiellement sur des défenses narcissiques, centrées notamment autour du clivage et le retournement sur soi, une identité fragile marquée par une image du corps et représentation de soi fragiles et un sur (dés) investissement des limites. Il s'agit d'une emprise sur le corps et sur les marques mêmes, permettant de retrouver l'objet et le recréer. À partir des principaux résultats obtenus, nous envisageons de travailler, en filigrane sur les spécificités des types de marquages corporels existant en Algérie. En effet si le présent travail s'est étayé sur une analyse prônant la globalité, un comparatif entre les types de marquages, de même, l'établissement d'un lien entre la symbolique de certaines pratiques et les soubassements psychodynamiques qui l'entourent, serait d'un apport considérable dans la compréhension du fait étudié dans ses moindres « recoins ». -- The problem of the physical markings as ancestral practices fit into contemporary forms of physical registration. We allowed to try to know if it was always about an expression of an important psychological illness? What can be the consequences? Why to mark the body? The application of this work articulated in two phases, at first, we operated by a large-scale pre- inquiry which grouped together 200 teenagers (10 girls and 190 boys). Then and in the second time we interrogated ten teenagers who mark the skin among which three boys, from fifteen to nineteen years old. Thanks to one « sorting approaches »: clinical Interview, tests of Rorschach and TAT. The results which we reached can be summarized as follows: these practices express a suffering which has difficulty in finding a way of symbolic expression other one than the body, the fear and the relation of object of the type anaclitique, the defensive organization would inform essentially about narcissistic defences, centred notably around the cleavage and the reversal on one, a fragile identity marked by an image of the body and the representation of one fragile and one on investment of the limits. It is about an influence on the body and on the marks, allowing to find the object and to recreate it. From the main obtained results, we intend to work, between the lines on the specificities of the types of physical markings existing in Algeria. Indeed if the present work supported on an analysis lauding the global nature, a comparative degree between the types of markings, also, the establishment of a link between the symbolism of certain practices and the bases psychodynamiques who surround him, would be of a considerable contribution in the understanding of the fact studied in its slightest « hidden recesses ».

Immersioultraäänitutkimuksen kehittäminen

Teräksenvalmistajilta edellytetään jatkuvasti panostusta laadun ja laadunvarmistuksen kehittämiseen. Teräksen laatu ja puhtaus korostuvat varsinkin silloin, kun terästä käytetään vaativiin käyttökohteisiin, kuten autoteollisuuden tarpeisiin. Ultraäänitarkastusmenetelmää käytetään laadun-varmistuksessa teräksen sisävikojen etsimiseen. Ultraäänitarkastuksessa lähetetään suuritaajuuksista ääntä kappaleeseen. Ääni etenee materiaalissa ja heijastuu erilaisista epäjatkuvuuskohdista. Luotaimeen palaavaa ääntä analysoimalla saadaan tietoa teräksestä ja sen sisävioista. Ultraäänitarkastuksen ongelmana on vian tyypin määrittäminen hankaluus sekä herkkyys tutkittavan materiaalin aineominaisuuksille. Työn tavoitteena oli immersioultraäänitarkastuksen kehittäminen sovellettuna teräksenvalmistajan tarpeisiin. Materiaalin aineominaisuuksista tutkittiin seostuksen vaikutusta. Teräslajit tarkastettiin valssitilaisena, karkaistuna ja normalisoituna. Lisäksi tutkittiin kappaleen pinnankarheuden ja -muodon vaikutusta tarkastukseen. Vikatyyppien tunnistamisen mahdollisuuksia ultra-äänitarkastuksessa selvitettiin käyttäen FFT- taajuusanalyysiä. Erilailla lämpökäsitellyillä teräslajeilla näytti eniten tuloksiin vaikuttavan terästen raekoko. Valssitilaisilla teräksillä raekoko on suuri, jolloin ultraääni vaimenee voimakkaasti teräksessä. Huomattavaa kuitenkin oli, että mikäli lämpö-käsittelyillä ei teräksen raekokoa saada juuri pienennettyä, ei myöskään vaimeneminen vähene. Tämän vuoksi lämpökäsittely ei välttämättä ole aina tarpeellinen valmisteltaessa ultraääninäytteitä. Fourier’n taajuusanalyysissä huomattiin olevan eroavaisuuksia verrattaessa huokosista ja sulkeumista palaavien kaikujen taajuusspektrejä. Näiden tulosten perusteella näyttäisi olevan mahdollista käyttää FFT- menetelmää ultraääni-tarkastuksessa vikojen luokitteluun.

Effects of manipulating Task Complexity on self-repairs during L2 oral production

This paper analyses the effects of manipulating the cognitive complexity of L2 oral tasks on language production. It specifically focuses on self-repairs, which are taken as a measure of accuracy since they denote both attention to form and an attempt at being accurate. By means of a repeated measures de- sign, 42 lower-intermediate students were asked to perform three different tasks types (a narrative, and instruction-giving task, and a decision-making task) for which two degrees of cognitive complexity were established. The narrative task was manipulated along +/− Here-and-Now, an instruction-giving task ma- nipulated along +/− elements, and the decision-making task which is manipu- lated along +/− reasoning demands. Repeated measures ANOVAs are used for the calculation of differences between degrees of complexity and among task types. One-way ANOVA are used to detect potential differences between low- proficiency and high-proficiency participants. Results show an overall effect of Task Complexity on self-repairs behavior across task types, with different be- haviors existing among the three task types. No differences are found between the self-repair behavior between low and high proficiency groups. Results are discussed in the light of theories of cognition and L2 performance (Robin- son 2001a, 2001b, 2003, 2005, 2007), L1 and L2 language production models (Levelt 1989, 1993; Kormos 2000, 2006), and attention during L2 performance (Skehan 1998; Robinson, 2002).

Prognosis of after spot volumes at the Scandinavian electricity market

The Thesis is dedicated to development of an operative tool to support decision making in after spot trading on the Nordic electricity market. The basics of the Nordic electricity market, trading mechanisms on the spot and after spot markets are presented in the Thesis. Mathematical equations that describe electricity balance condition in the power system are offered. The main driving factors that impact deviation of actual electricity balance from the scheduled one (object) in the power system have been explored and mathematically defined. The behavioral model of the object and principal trends in change of state of the object under an impact of the driving factors are determined with the help of regression analysis made in Microsoft Office Excel. The behavioral model gives an indication for the total regulation volume (Elbas trades volume, volume of regulation market, balance power) for a certain hour that serves as the base input in estimating prices on the after spot markets. Proposals for development of methodologies of forecasting the after spot electricity prices are offered.

Att lära för livet hemma och i skolan : elevers uppfattningar av kost och hälsa, konsumtion och privatekonomi samt hushåll och miljö

The home is an important societal arena for upbringing and learning. A child can experience a feeling of participation in the household he or she belongs to very early in life. In this manner, the home environment constitutes an essential foundation for instruction in the subject of Home Economics. At school, Home Economics pupils should fulfill the intentions that school curriculum has for the subject, that is to say develop the knowledge, skills, and values that allow pupils to be able to take responsibility for their health, finances, comfort, and safety in their close environment. The purpose of this study is twofold. Firstly, the study aims to examine what knowledge and attitudes children and teenagers have acquired from their home environment, close environment, as well as school. Secondly, the study aims to evaluate the effects of instruction in Home Economics, at the 7th grade level, as regards diet and health, consumption and private finances, as well as household and the environment. The study’s methodological foundation focuses on pupils’ understanding of the surrounding world. A phenomenographical approach to the research phenomenon basis itself on the supposition that knowledge is fixed in human beings’ consciousness and experiences. Furthermore, the study stresses individual variations in conjunction with the experienced phenomenon. The empirical portion of the study is based on semistructured interviews of 30 pupils divided into two reference groups. The pupils were interviewed before instruction in the subject of Home Economics started and upon completing instruction. The interview data was analyzed and interpreted in accordance with the “multistage model”. The study results show that upbringing in the home environment is determinative as pertains to understanding of the socio-cultural household environment. Mealtime traditions, for example, are deeply ingrained but nonetheless influenced by lifestyle changes. The study shows that a didactic challenge exists to draw attention to the consequences of poor mealtime habits and stress for everyone raising or educating children and teenagers. Despite good knowledge of what a healthy diet is, the majority of pupils choose fast-food and junk-food when they eat out to save time and money. Studies of pupils’ preparedness for consumption show that a purposeful upbringing in the home in combination with relevant instruction in Home Economics, results in knowledgeable consumers. This study also shows that upbringing in the home environment and instruction in Home Economics requires an intense and conscious focus on the consequences of a household not run in accordance with nature, where the household lifestyle is nonsustainable. Pupils’ understanding is often based on the disregarding of the survival perspective for a comfort perspective. Parents and Home Economics teachers should be able to bring up and teach children and teenagers in a manner that allows children and teenagers to take responsibility for their health, private finances, as well as comfort and safety in the close environment. The method is conscious nurturing and instruction.

The radio frequency identification technology in the supply chain management: a case of a big logistics company

Nowadays global business trends force the adoption of innovative ICTs into the supply chain management (SCM). Particularly, the RFID technology is on high demand among SCM professionals due to its business advantages such as improving of accuracy and veloc-ity of SCM processes which lead to decrease of operational costs. Nevertheless, a question of the RFID technology impact on the efficiency of warehouse processes in the SCM re-mains open. The goal of the present study is to experiment the possibility of improvement order picking velocity in a warehouse of a big logistics company with the use of the RFID technology. In order to achieve this goal the following objectives have been developed: 1) Defining the scope of the RFID technology applications in the SCM; 2) Justification of the RFID technology impact on the SCM processes; 3) Defining a place of the warehouse order picking process in the SCM; 4) Identification and systematization of existing meth-ods of order picking velocity improvement; 5) Choosing of the study object and gathering of the empirical data about number of orders, number of hours spent per each order line daily during 5 months; 6) Processing and analysis of the empirical data; 7) Conclusion about the impact of the RFID technology on the speed of order picking process. As a result of the research it has been found that the speed of the order picking processes has not been changed as time has gone after the RFID adoption. It has been concluded that in order to achieve a positive effect in the speed of order picking process with the use of the RFID technology it is necessary to simultaneously implement changes in logistics and organizational management in 3PL logistics companies. Practical recommendations have been forwarded to the management of the company for further investigation and procedure.

Statistical analysis of event-related potential elicited by verb-complement merge in Brazilian Portuguese

An interesting fact about language cognition is that stimulation involving incongruence in the merge operation between verb and complement has often been related to a negative event-related potential (ERP) of augmented amplitude and latency of ca. 400 ms - the N400. Using an automatic ERP latency and amplitude estimator to facilitate the recognition of waves with a low signal-to-noise ratio, the objective of the present study was to study the N400 statistically in 24 volunteers. Stimulation consisted of 80 experimental sentences (40 congruous and 40 incongruous), generated in Brazilian Portuguese, involving two distinct local verb-argument combinations (nominal object and pronominal object series). For each volunteer, the EEG was simultaneously acquired at 20 derivations, topographically localized according to the 10-20 International System. A computerized routine for automatic N400-peak marking (based on the ascendant zero-cross of the first waveform derivative) was applied to the estimated individual ERP waveform for congruous and incongruous sentences in both series for all ERP topographic derivations. Peak-to-peak N400 amplitude was significantly augmented (P < 0.05; one-sided Wilcoxon signed-rank test) due to incongruence in derivations F3, T3, C3, Cz, T5, P3, Pz, and P4 for nominal object series and in P3, Pz and P4 for pronominal object series. The results also indicated high inter-individual variability in ERP waveforms, suggesting that the usual procedure of grand averaging might not be considered a generally adequate approach. Hence, signal processing statistical techniques should be applied in neurolinguistic ERP studies allowing waveform analysis with low signal-to-noise ratio.

Formal modelling for digital media distribution

Human beings have always strived to preserve their memories and spread their ideas. In the beginning this was always done through human interpretations, such as telling stories and creating sculptures. Later, technological progress made it possible to create a recording of a phenomenon; first as an analogue recording onto a physical object, and later digitally, as a sequence of bits to be interpreted by a computer. By the end of the 20th century technological advances had made it feasible to distribute media content over a computer network instead of on physical objects, thus enabling the concept of digital media distribution. Many digital media distribution systems already exist, and their continued, and in many cases increasing, usage is an indicator for the high interest in their future enhancements and enriching. By looking at these digital media distribution systems, we have identified three main areas of possible improvement: network structure and coordination, transport of content over the network, and the encoding used for the content. In this thesis, our aim is to show that improvements in performance, efficiency and availability can be done in conjunction with improvements in software quality and reliability through the use of formal methods: mathematical approaches to reasoning about software so that we can prove its correctness, together with the desirable properties. We envision a complete media distribution system based on a distributed architecture, such as peer-to-peer networking, in which different parts of the system have been formally modelled and verified. Starting with the network itself, we show how it can be formally constructed and modularised in the Event-B formalism, such that we can separate the modelling of one node from the modelling of the network itself. We also show how the piece selection algorithm in the BitTorrent peer-to-peer transfer protocol can be adapted for on-demand media streaming, and how this can be modelled in Event-B. Furthermore, we show how modelling one peer in Event-B can give results similar to simulating an entire network of peers. Going further, we introduce a formal specification language for content transfer algorithms, and show that having such a language can make these algorithms easier to understand. We also show how generating Event-B code from this language can result in less complexity compared to creating the models from written specifications. We also consider the decoding part of a media distribution system by showing how video decoding can be done in parallel. This is based on formally defined dependencies between frames and blocks in a video sequence; we have shown that also this step can be performed in a way that is mathematically proven correct. Our modelling and proving in this thesis is, in its majority, tool-based. This provides a demonstration of the advance of formal methods as well as their increased reliability, and thus, advocates for their more wide-spread usage in the future.
