Full textAbstract:
This corpus-based keyword analysis study investigated the letters to the shareholders from two commercial banks, Bank of America and Citigroup,
over a three-year period from 2008, 2009, and 2010. The letters were
compiled to facilitate a diachronic assessment of profit/loss reporting from
two prominent institutions over a time period in which the recession commenced, peaked, and concluded. To conduct the analysis on the node
texts, two sets of reference corpora were compiled. The first reference corpus
set consisted of the letters to shareholders from eight consistently high-performing corporations not within the commercial banking industry for each
of the three years; the second reference corpus set consisted of the letters from the 10 banking institutions that also appeared in the Fortune 500 listings for
the three period. The corpus-based analysis revealed that in years of low performance companies create messages that assert a vision and forward a strategy for ensuring future success while also deflecting responsibility for
past failure. In contrast, when companies perform well, the keyword lists
display a clear tendency of the company and the author to accept praise and responsibility for high performance.

Full textAbstract:
This study aims to contribute to the understanding of ideology conveyed by lexical items and framing of texts. Since ideology is embedded in language the frames used in newspapers construct a narrow ideological perspective for the readers to interpret subjects and events through. On the basis of editorials from The Washington Post and The Washington Times that cover President Barack Obama, the study examines how the editorials differ in their framing of Obama and which discourses and keywords occur unusually frequently in each newspaper. Findings suggest that when it comes to framing, The Washington Post allows for a relatively balanced perspective on Obama as they both support and criticise him, while The Washington Times overwhelmingly condemns and attacks Obama. A keyword analysis points to unusually frequent discourses on race, conservatives and reforms in The Washington Post, and spending, unemployment and political institutions in The Washington Times. Because of their ideological differences the newspapers construct a reality where the subject, Obama, is presented in very different ways.

Full textAbstract:
I registri distribuiti o Distributed Ledger Technology (DLT) sono un particolare tipo di architettura che consente la memorizzazione di dati in maniera distribuita e permanente, senza l'ausilio di un entità centrale. Il primo esempio di tecnologia DLT è rappresentato dalla struttura dati Blockchain, sviluppata per la gestione della criptovaluta Bitcoin. Da quella prima implementazione ne sono seguite altre, che spaziano ad altri campi applicativi e che perciò possiedono caratteristiche diverse dalla tipica struttura a blocchi. Tra queste si trova IOTA, una criptovaluta sviluppata in riferimento all’ambiente dell’Internet of Things (IOT), la quale permette di effettuare micro transazioni a costo zero (zero fee). Una delle caratteristiche più importanti di IOTA è il protocollo di comunicazione MAM, attraverso il quale vengono creati canali di messaggi di tipo publisher-subscriber. La creazione e la scrittura di questi è funzionale e potente, ma la ricerca è possibile solamente conoscendo un indirizzo denominato root. Lo scopo di questo progetto di tesi è presentare una struttura distribuita in grado di eseguire query keyword-based all'interno del registro IOTA. E’ stato progettato un overlay basato su Distributed Hash Table (DHT) con topologia a ipercubo. A partire da un set di keyword, la struttura DHT indicizza i messaggi MAM, ma non li replica, garantendo così l’integrità dei dati che tanto contraddistingue i registri distribuiti. Infine, è presentata una riflessione sui Permanode, particolari nodi all'interno di IOTA.

"Zinc and nickel disrupt tubular vacuole and mitochondrial networks, but only nickel disrupts microtubules in hyphal tip cells of two Paxillus involutus strains."

Full textAbstract:
Ectomycorrhizal fungi are able to ameliorate heavy metal stress to host trees in polluted soils. Their sensitivity or tolerance to heavy metals is usually examined based on growth and proliferation on heavy metal amended media. However, there are no data on cellular effects of heavy metals and detoxification in live cells of these fungi. Organelle morphology has recently been recognized as an indication of cellular health and its changes can be used to assess cytotoxicity. The aim of this study was, therefore, to investigate short term effects of common heavy metal pollutants, Zn2+ and Ni2+ on the morphology of vacuoles, mitochondria and microtubules in hyphal tip cells of two Paxillus involutus strains. Vacuoles, mitochondria and microtubules were labeled with Oregon Green?? 488 carboxylic acid diacetate, 3,3'-dihexyloxacarbocyanine iodide ((DiOC6(3)) and anti-??- tubulin antibodies, respectively. They were treated with 0-1 mmol L-1 NiSO4 or 0-100 mmol L-1 ZnSO4 or K2SO4 (SO4 2- control) and examined by fluorescence microscopy. Vacuoles and mitochondria in untreated hyphal tip cells of strain P2 which originated from a heavy metal-rich soil were motile and tubular forming networks. Exposure to the metals caused tubular vacuole thickening and vesiculation as well as fragmentation of tubular mitochondria in living hyphal tip cells. The highest K2SO4 concentration also had severe effects on mitochondria. These effects were metal, concentration and exposure time dependent. NiSO4 caused these effects at a hundred fold lower concentration than ZnSO4 and induced severe microtubule disruption. Vacuole tubularity recovered after removal of the metal solutions depending on the metal, concentration and exposure time. Mitochondrial tubularity recovered to pretreatment morphology in a shorter time and even during exposure to the highest metal concentration. Vacuoles of strain P46 which originated from a non-polluted soil were pleomorphic, but mainly spherical with occasional tubular interconnections. The vacuoles were too sensitive to UV light exposure required for fluorescence microscopy to investigate their response to heavy metals. The mitochondrial network and microtubules resembled those of strain P2. The highest ZnSO4 and NiSO4 concentrations caused similar trends in response of mitochondria and microtubules of the two strains. However, mitochondria of strain P46 were less sensitive at lower metal concentrations. The highest K2SO4 concentration had more severe effects on mitochondria of strain P46 than in strain P2 from which tubularity was not recovered. This investigation is the first to reveal that heavy metals affect organelle morphology in two strains of an ectomycorrhizal fungus. Nickel effects on the organelles are likely to result from microtubule disruption. Metal induced mitochondrial fragmentation is possibly an apoptotic response and the recovery of tubular organelle networks suggests cellular detoxification.

Akhavantabasi, Shiva. "Functional Characterization Of Two Potential Breast Cancer Related Genes." Phd thesis, METU, 2012. http://etd.lib.metu.edu.tr/upload/12614275/index.pdf.
Full textAbstract:
Cancer may arise as a result of deregulation of oncogenes and/or tumor suppressors. Although much progress has been made for the identification of such cancer related genes, our understanding of the complex tumorigenesis pathways is still not complete. Therefore, to improve our understanding of how certain basic mechanisms work in normal and in cancer cells, we aimed to characterize two different breast cancer related genes. First part of the study focused on subcellular localization USP32 (Ubiquitin Specific Protease 32) to help understand the function of this uncharacterized gene. USP32 is a member of deubiquitinating enzymes (DUBs) and the gene maps to a gene rich region on 17q23. Genes on 17q23 are known to undergo amplification and overexpression in a subset of breast cancer cells and tumors. DUBs are known to be implicated in a variety of cellular functions including protein degradation, receptor endocytosis and vesicle trafficking. Therefore to elucidate the function of USP32, we localized the full length USP32 protein fused to GFP, in HeLa cells, using Fluorescence Protease Protection (FPP) assay and confocal microscopy. Results suggested a Golgi localization for USP32 as confirmed by co-localization study via BODIPY-TR, a Golgi specific marker. Additional investigations to find the role of USP32 in Golgi will further clarify the function of this candidate oncogene. Second part of the study focused on a potential tumor suppressor. For this purpose, we functionally characterized miR-125b, a microRNA gene as a potential tumor suppressor in breast cancer. microRNAs are regulators of gene expression and their deregulation is detected in cancer cells. miR-125b is reported as a down regulated microRNA in breast cancers. In this study, we investigated the expression, function and possible targets of miR-125b in breast cancer cell lines (BCCLs). Our results revealed a dramatic down regulation of miR-125b in a panel of BCCLs. Restoring the expression of miR-125b in low miR-125b expressing cells decreased the cell proliferation and migration as well as cytoplasmic protrusions, detected by staining of actin filaments. While connection of miR-125b and cell motility based on ERBB2 targeting has been reported earlier, here we present data on ERBB2 independent effects of miR-125b on cell migration in non-ERBB2 overexpressing breast cancer cells. Our results showed involvement of a miR-125b target, ARID3B, in cell motility and migration. Our findings showed miR-125b to be an important regulator of cell proliferation and migration in ERBB2 negative breast cancer cells, possibly through regulating multiple targets.

Baykal, Cuneyt. "Two-dimensional Depth-averaged Beach Evolution Modelling." Phd thesis, METU, 2012. http://etd.lib.metu.edu.tr/upload/12614148/index.pdf.
Full textAbstract:
In this study, a two-dimensional depth-averaged beach evolution numerical model is developed to study the medium and long term nearshore sea bottom evolution due to non-cohesive sediment transport under the action of wind waves only over the arbitrary land and sea topographies around existing coastal structures and formations. The developed beach evolution numerical model is composed of four sub-models: a nearshore spectral wave transformation model based on energy balance equation including random wave breaking and diffraction terms to compute the nearshore wave characteristics, a nearshore wave-induced circulation model based on the non-linear shallow water equations to compute the nearshore depth averaged wave-induced current velocities and mean water level changes, a sediment transport model to compute the local total sediment transport rates occurring under the action of wind waves and a bottom evolution model to compute the bed level changes in time due to gradients of sediment transport rates in cross-shore and longshore directions. The governing partial differential equations are solved utilizing finite difference schemes. The developed models are applied successfully to several theoretical and conceptual benchmark cases and an extensive data set of laboratory and field measurements. As an alternative approach to be used in beach evolution problems, a distributed total sediment load formula is proposed based on the assumption that the local total sediment transport rates across the surf zone are proportional to the product of the rate of dissipation of wave energies due to wave breaking and wave-induced current velocities. The proposed distribute load approach is validated with the available laboratory and field measurements.

Full textAbstract:
The objective of this study is to illustrate that phase separation improves the efficiency of an anaerobic system which digests semi-solid organic wastes. Organic fraction of municipal solid waste (OFMSW) was the semi-solid organic waste investigated. In the first part of the study, the optimum operational conditions for acidified reactor were determined by considering the volatile solid (VS) reductions and average acidification percentages at the end of two experimental sets conducted. Organic loading rate (OLR) of 15 g VS/L.day, pH value of 5.5 and hydraulic retention time (HRT) of 2 days were determined to be the optimum operational conditions for the acidification step. Maximum total volatile fatty acid and average acidification percentage were determined as 12405 mg as HAc/L and 28%, respectively in the reactor operated at optimum conditions. In the second part, an acidification reactor was operated at the optimum conditions determined in the first part. The effluents taken from this reactor as well as the waste stock used to feed this reactor were used as substrate in the biochemical methane potential (BMP) test. The results of BMP test revealed that the reactors fed by acidified samples indicated higher total chemical oxygen demand (tCOD) removals (39%), VS reductions (67%) and cumulative gas productions (265 mL).
The result of this study indicated that the separation of the reactors could lead efficiency enhancement in the systems providing that effective control was achieved on acidified reactors.

Full textAbstract:
Aim: The purpose of this study was to investigate docosahexaenoic acid (DHA) ingestion on muscle damage and inflammation during the first two weeks of a novice resistance training (RT) program.
Methods: This study was a placebo-controlled, double-blind design. Forty-one healthy untrained males between the ages of 18 and 28 years consumed 2,000 mg/d of either DHA or corn oil (PCB) for 44 days including a 28 day loading period. Serum fatty acids were analyzed to determine treatment efficacy. During the 17 day training period, an acute eccentric exercise bout was implemented followed by a full-body RT regimen thrice weekly. Six fasted blood draws (days 1, 2, 4, 7, 12, and 17) during this exercise period were analyzed for creatine kinase (CK) and C-reactive protein (CRP). Maximum isometric strength (ISO) of the elbow flexors, delayed onset muscle soreness (DOMS), and range of motion (ROM) were measured on day 1 prior to exercise and also on days 2, 3, 4, 7, 12, and 17.
Results: The CK response and the area under the curve (AUC) analysis for DOMS trended to decrease in the DHA group in comparison to placebo (p=0.0925 and p=0.0536, respectively). Treatment showed no effect on CRP levels. DHA supplementation significantly increased serum DHA by 380% as a proportion of total fatty acids (p<0.0001). Conclusion: This study does not demonstrate convincing benefits of DHA ingestion to recovery from a new resistance exercise program but does suggest a need for further investigation.Master of Science

Full textAbstract:
The primary purpose of a trademark is to facilitate the communication of information between consumers and producers about their products and services to those who wish or need to buy them. The consumer needs to be able to depend on the message the mark conveys to ensure they are purchasing what will fulfil their requirements. In the modern market place, the choice appears endless, and indeed the principles of free trade espoused by the European treaties has heightened the opportunities for cross-national traders to sell their goods, and increased the options available to consumers. When this occurs, so does the availability of information which a purchaser may find the need to seek through to ascertain what he or she wants in an complex and often confusing exercise in differentiation. It is therefore in the interests of producers and customers that those who manufacture goods or provide services develop a mark which identifies their wares and helps provide feedback measured by success; consequently an exchange of information. Consumers are able to make their preferences known via choice, or otherwise, of the mark. Modern business methods and the vast array of marketing opportunities are not only placing the role and function of the trademark at the forefront of consumer protection, but also developing the concept of the mark as an asset of considerable value in itself. This increases its vulnerability to competitive interference and the proposition that it should receive enhanced protection in law. Somewhat perversely, it has resulted in a body of legislation and jurisprudence which lacks cogency and coherence. The purpose of this thesis, accordingly, is to examine the causes thereof by evaluating the current European trademarks protection system to ascertain the contribution they actually make to promotion of free competition and the movement of goods or services upon which that substantial market is predicated. It will examine the impact of the development of protection granted to the trademark with particular reference to the use of online keywords advertising service and focus on the effect of relatively new theories of what functions qualify to be shielded from harm from competitive others. This has expanded beyond the conventional boundaries of source ‘origin’ protection, espoused to primarily protect consumers from confusion in their choice making process. Advertising and investment functions as separate principle are recognised by the Court of Justice of the European Union, but do not appear to qualify for safeguarding in the context of the competitive free market. In fact, it will be shown that giving excessive shelter from harm to all functions which may affect the value of the trademark will limit, even jeopardise, third party competitor and consumer issues. It will inhibit the use of the e-commerce online keywords advertising service which assists third parties to promote alternative competing goods or services and so reduce consumer choice by restriction of online information. It is suggested that proper, clear defences must be guaranteed under the law so third parties may gauge their actions to avoid infringement of trademark owner rights whilst promoting their own products, and accordingly strike the necessary balance between the different competing interests of trademark owners, third parties competitors, and consumers.

Sammanfattning
Funktionshinder och arbete bildar tillsammans ett aktuellt ämne som ses behöva ökade
kunskaper för att nå Sveriges målsättning om ”Ett arbetsliv för alla”. Inom området diskuteras
hur och vad som kan genomföras i syfte att minska det utanförskap och fördomar som kan
finnas.
Idag finns möjligheten för individer med funktionshinder att arbeta i en anpassad
arbetssituation. För att uppmärksamma individens egen upplevelse av ovanstående valde
författarna att genomföra en kvalitativ studie med syfte att beskriva individens upplevelse av
att arbeta i en anpassad arbetssituation. Författarna använde målinriktat urval och genomförde
därefter ostrukturerade intervjuer med tio informanter som arbetar i en anpassad
arbetssituation, vilka berättade och delgav sina upplevelser. Studien resulterade i tre
övergripande teman, Bemötande, Delaktighet och Förändrad arbetssituation. Inom dessa
teman presenteras informanternas upplevelser av att vara utsatt till följd av att arbeta i en
anpassad arbetssituation. Upplevelsen beskrivs både som positivt och negativt. Den anpassade
arbetssituationen upplever informanterna vara en förutsättning för att kunna arbeta.
Anpassningen förändrar arbetsrollen och upplevs ge en känsla av begränsning på
arbetsmarknaden. Bemötandet på den anpassade arbetsplatsen beskriver informanterna kan
vara både som stöd eller hinder.
Summary
To work in an adapted work situation -ten individuals tell their stories.
Disability and work, put together, becomes a burning question that requires further knowledge
for to reach the goal in Sweden; “A working life for everyone”. In this subject it is discussed
how and what there needs to be done to reduce the gap, the prejudice and the feeling of
alienation which there may occur.
In today people with a disability are given an opportunity to work in an adapted work
situation. To observe the individuals own experience of the question mentioned before the
authors chose to do a qualitative study with the aim to describe the individual’s experience of
working in an adapted work situation. The authors used a purposeful sampling and made
unstructured interviews with ten individuals who expressed their experiences. The result is
presented within three themes, Treatment, Participation and Changed work situation which
present the individuals experience of being exposed because of the adapted work situation.
The experience is described as both positive and negative. The individuals experience the
adapted work situation as a necessary condition to be able to work. The adaption changes the
worker roll and is experienced as a feeling of being limited on the labour market. The
treatment at the working site is described as being either supportive or non-supportive.

Full textAbstract:
MMA (mixed martial arts) has expanded globally as entertainment, training and competition in recent years. MMA is a sport where techniques such as punches, kicks, throws and joints are used to defeat the opponent in unarmed close combat. Standing techniques such as punches and kicks are of great importance in sports and coaches / athletes strive to develop efficient techniques. The study investigates how UFC athletes work with distance moves relative to each other in knockout or tech knockout matches, comparisons were also made between a heavier and an easier weight class to detect any differences in behavior. Data was collected through a match observation where a total of 50 matches from the MMA event were collected with reverse chronological order starting from fight night Johnson VS Reis. The results showed that there were differences between movement and non-occupation at KO / TKO, but also that they were not significant. The same conclusion was made for comparisons between the weight classes. When there was an individual move, it was most common for it to move forward and the most common movement between athletes was forwards. Handling of dynamic and static distances is likely to have impact on elite athletes within MMA, but the results show that the difference between athletes in different weight classes is not significant and is likely to be affected to an equal extent by individual athletes' skills.Kampsporten MMA (mixed martial arts) har expanderat globalt som underhållning, träning och tävling under de senaste åren. MMA är en sport där tekniker som slag, sparkar, kast och ledlås används för att besegra motståndaren i obeväpnad närkamp. Stående tekniker som slag och spark är av stor vikt inom sporten och tränare/atleter strävar efter att utveckla dessa tekniker på effektivaste sätt. Studien undersöker hur atleter inom UFC arbetar med distanshantering i förhållande till varandra vid matcher som avgjordes med knockout eller tekniskknockout, jämförelser gjordes också mellan en tyngre och en lättare viktklass för att påvisa eventuella skillnader i beteende. Data samlades in genom en matchobservation där totalt 50 matcher från MMA event samlades in med omvänd kronologisk ordning med start från galan fight night Johnson VS Reis. Resultatet visade att det fanns skillnader mellan rörelse och ickerörelse vid KO/TKO, men också att dessa inte var signifikanta. Samma slutsats gällde vid jämförelser mellan viktklasserna. När det skedde en enskild rörelse var det vanligaste att den skedde framåt och den vanligaste rörelsekombinationen mellan atleterna var framåt-framåt. Hantering av dynamisk och statiskdistans har med stor sannolikhet en betydande inverkan för elitatleter inom MMA, men resultatet visar att skillnaden mellan atleter i olika viktklasser inte är signifikant och påverkas troligen i lika stor utsträckning av individuella färdigheter hos atleterna.

Full textAbstract:
Bakgrund: Fibromyalgi är ett syndrom och ett kroniskt tillstånd som orsakar smärta, ömhet och stelhet i rörelseorganen. Fibromyalgi karaktäriseras också av sömnstörningar, fatigue, ångest, depression och problem med tarmfunktionerna. Syfte: Att beskriva kvinnors upplevelser av att leva med fibromyalgi och vilka copingstrategier de använder för att hantera sin situation. Metod: Litteraturstudie med deskriptiv design. Resultat: Kvinnor med fibromyalgi upplevde en oförutsägbar fluktuerande och utbredd smärta, en ständigt närvarande fatigue, stelhet samt kognitiva svårigheter. De kognitiva svårigheterna visade sig som bland annat koncentrations- och minnessvårigheter. Att leva med fibromyalgi ansågs av kvinnorna som emotionellt påfrestande. Frustration, ångest och depression var vanligt förekommande och många kvinnor upplevde en misstro och oförståelse från sin omgivning. Fibromyalgin hade en stor inverkan på kvinnornas sociala liv som arbetsliv och dagliga aktiviteter. För att hantera sin fibromyalgi använde kvinnorna sig av olika fysiska och mentala copingstrategier. Slutsats: En ökad kunskap hos omgivningen om hur det är att leva med fibromyalgi kan leda till ökad förståelse och därmed ett gott bemötande till dessa kvinnor. Detta kan generera en känsla av bekräftelse, främja hanteringen av fibromyalgin samt minska kvinnornas lidande.Background: Fibromyalgia is a syndrome and a chronic condition which causes pain, soreness and stiffness in the musculoskeletal system. Fibromyalgia is additional characterized by sleep disorder, anxiety, depression and bowel functional problems. Aim: Describe women’s experiences of living with fibromyalgia and which coping strategies they use for handling their situation. Method: A literature review with descriptive design. Result: Women with fibromyalgia experienced an unpredictable, fluctuating and widespread pain, an ever-present fatigue, stiffness and cognitive difficulties. The cognitive difficulties found to include concentration difficulties and memory problems. Living with fibromyalgia was considered by the women as emotionally stressful. Frustration, anxiety and depression were common. Many women experienced mistrust and incomprehension from the surroundings. Fibromyalgia had a great impact on women’s social life such as work life and daily activities. To manage their fibromyalgia, the women used various physical and mental coping strategies. Conclusion: An increased knowledge from the surroundings about how it is to live with fibromyalgia could lead to increased understanding and good treatment for these women. That could generate confirmation, promote the management of fibromyalgia and decrease the suffering for these women.

Full textAbstract:
The transition from primary to secondary school is regarded as one of the most difficult in children’s educational careers and the negative academic, social and emotional effects of an unsuccessful transition have been widely documented, with many practitioners identifying the transition to secondary school as a key intervention point (Galton, Morrison and Pell, 2000, Turnbull, 2006). Shy and socially withdrawn children are particularly vulnerable at this time. Pyramid Clubs, a short-term selective and preventative therapeutic group intervention offer a promising model of support, but a robust evidence-base is currently lacking (Munoz, Mrazek, and Haggerty, 1999; Shepherd and Roker, 2005). This study evaluated the use of a Pyramid Club to provide a ‘bridge’ of support before, during and following nine children’s transition to secondary school. The study was conducted from a critical realist stance and quantitative and qualitative methodology were adopted within an embedded single-case study design. The study had two aims; to evaluate the effectiveness of the club; and to explore the process, in order to understand the club’s mechanism of effect. Pre-and post-intervention teacher report data were collected in conjunction with club leader, club member and parents’ perspectives, obtained though focus groups and individual interviews. The researcher also observed each club meeting. Data were analysed using descriptive statistics and thematic analysis. The findings indicate the club offers an effective method of support. The children enjoyed the club experience and a range of social-emotional gains were reported. The findings were used to propose a theoretical framework based on the concept of resilience, to explain how Pyramid Clubs can be successfully used to support vulnerable children’s transition to secondary school. Core elements, which were considered to be essential components of the intervention, were identified to aid future implementation and evaluation of Transition Pyramid Clubs.

Full textAbstract:
The problem of determining whether or not a theoretical model is an accurate representation of an empirically observed phenomenon is one of the most challenging in the empirical scientific investigation. The following study explores the problem of stochastic model validation. Special attention is devoted to the unusual two-peaked shape of the empirically observed distributions of the conditional on realised volatility financial returns. The application of statistical hypothesis testing and simulation techniques leads to the conclusion that the conditional on realised volatility returns are distributed with a specific previously undocumented distribution. The probability density that represents this distribution is derived, characterised and applied for validation of the financial model.

Full textAbstract:
This dissertation aims to provide evidence on the inter-relationship between per-capita income variation and worker effort indices through nutritional intakes or income to food expenditure ratio. Based on these worker effort indices, there are two data sets69 countries data for the year 1980, 1990 and 2000 and 17 regionalized Turkish provinces data for 1994 and 2003. One major contribution is the definition of human and physical capital interactions since accumulation of human capital (H) and physical capital (K) depends on each other within a given technology. This is called &ldquo
complementary interaction&rdquo
. Therefore, we emphasize K and H ratios are key factors in an economy rather than the absolute sizes. Another our main contribution to the literature is the data sources we employ. The 1980, 1990 and 2000 data are the first in the literature for 69 countries and more importantly, it is the first study for Turkish provincial level. While some studies are held for particular countries in terms of health proxy levels, there is no such study of any type pertaining to the Turkish economy. Our health proxies empirically play a very important role in our economic growth study. While health proxies make an important contribution in explaining income disparity approach, we do not see such effect on the convergence rate.

In this essay, I will look at three different Compulsory comprehensive schools in one community and I will compare final grades from students who graduated in spring 2006. I will also examine how the three schools work with students, and in what way they approach students with dyslexia/reading- and writing difficulties, so that they could reach goals set by The Swedish National Agency for Education. The aim with this essay is to show differences between schools in the same community and my question is if it is the way you approach students with dyslexia/reading- and writing difficulties that affects the student’s grades and results.
The study is concentrating on three schools in one community and students with dyslexia and reading- and writing difficulties that went to those schools. I have spoken to remedial teacher at each school about how they approach students with dyslexia/reading- and writing difficulties, what kind of methods the use, how they investigate if a student is in need of special help and how they grade their students who are in need of special teaching because of their learning disabilities. This essay will also present different ways of defining dyslexia and how to approach the pedagogic difficulties that will appear in situations where students with reading- and writing difficulties gets exposed and are in need of special education or help.
The results of this study can only be connected to those schools that have been studied for this exam. The results can not in any way be generalising for all schools in Sweden. However did the study results show that students that went to school 2 reached higher goals than students that went to school 1 or 3. The study also shows that these schools use different ways to work with students with dyslexia and reading- and writing difficulties. But to compare numbers and grades can’t give a fair picture of how each school work with each student so that they develop those skills and knowledge that is seen as necessary to become a democratic member of the society. Because numbers and grades cant tell anything about the student’s disabilities or what kind of knowledge or skills the student is in possession of. Nevertheless can this study when comparing grades, in the most general way, say that students that go to school 2 are more likely to reach goals that are set by The Swedish National Agency for Education.

Full textAbstract:
In this thesis it is aimed to compile the Turkish strong-motion database for its efficient use in earthquake engineering and strong-motion seismology related studies. Within this context, the Turkish strong-motion database is homogenized in terms of basic earthquake source parameters (e.g. magnitude, style-of-faulting) as well as site classes and different source-to-site distance metrics. As part of this objective, empirical relationships for different magnitude scales are presented for further harmonization of the database.
Data processing of the selected raw (unprocessed) strong-motion accelerograms that do not suffer from non-standard problems are realized. A comparative study is also conducted between the peak ground-motion values of Turkish strong-motion database with the estimations computed from different ground-motion prediction models. This way the regional differences of Turkish database are evaluated by making use of global prediction models.
It is believed that the main products of this thesis will be of great use for reliable national seismic risk and hazard studies.

Health problems of the human beings in a society are one of the main components of the social security systems due to the dimension of the financial burden it might bring on individuals, employers, insurance companies and governments. Morbidity measures, such as incidence and prevalence of a specific disease in a certain population enable researchers to estimate for individuals the probability of being diagnosed or being prone to the diseases. This information is usually not tractable because of the non-availability of the convenient data or recordings for many countries as well as Turkey. Even if it is available, it is commonly limited with largely varying characteristics about the type and coverage of the diseases. In this regard, the pattern that a population follows for an acute disease may not be the same for chronic diseases. Having those indicators determined for a group of insureds will enable underwriters to have more profitable and economical premium calculation and precision on required reserve estimation.

Abstract In this study, the role-playing game Final Fantasy 7 was analysed in regards of its qualities for English language development. Areas concerning language, specifically vocabulary, and video games explored in this study were academic words, words that express time, collocations, frequency, and keywords. Other areas investigated in this study are video games in connection to the syllabus for English, students’ outside of school interests, and implications for teaching. Data from a corpus-based vocabulary analysis showed that the players of Final Fantasy 7 will encounter a rich variety of words and linguistic features. Further, the text of Final Fantasy 7 shares a lot of the same qualities with texts from English 5 and 6, concerning academic words. Although, an analysis of keywords in the game and in the school texts also showed some differences, mainly in terms of grammatical variations, which indicate that Final Fantasy 7 can function as a complement to typical school texts.

Resumo UCHÔA-FIGUEIREDO, L. R. O impacto da doença na vida cotidiana dos cuidadores de crianças com epilepsia de dificil controle. 2009. 260f. Tese (Doutorado) Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, São Paulo, 2009. A notícia de que o filho tem uma doença crônica remete os pais a uma crise em relação às expectativas decorrentes do desejo do filho idealizado. A família sofre pela incerteza da evolução da doença e suas possíveis consequências. A mãe, comumente, torna-se a cuidadora principal, ajudando a suprir necessidades, apresentando uma vida ocupacional deficitária, pois despende tempo, energia física e emocional, sofrendo perdas, sobrecarga de atividades e comprometendo a sua qualidade de vida. O objetivo desta pesquisa foi conhecer as mudanças que ocorrem na vida cotidiana do cuidador primário de pacientes, com diagnóstico de Epilepsia de Difícil Controle Infantil associado à encefalopatia crônica não evolutiva, avaliar a qualidade de vida e a sobrecarga em função da situação de adoecimento e verificar a relação desta sobrecarga emocional com a percepção dos cuidadores, sobre sua qualidade de vida. Avaliaram-se 50 cuidadores de crianças entre 7 e 12 anos, de ambos os sexos, com diagnóstico confirmado há cinco anos, e que estavam nesta função há pelo menos dois anos. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa Envolvendo Seres Humanos do HCFMRP e foi realizada no Serviço de Epilepsia Infantil do mesmo hospital. Foram utilizados: prontuários médicos das crianças, entrevista semi-estruturada enfocando o adoecimento, o cuidar e a vida cotidiana, os questionários de sobrecarga, Caregiver Burden Scale e de Qualidade de Vida, WHOQOL-bref. Os dados obtidos na entrevista foram analisados segundo o Sistema Quantitativo Interpretativo. Os dados do WHOQOL-bref e da Caregiver Burden Scale foram submetidos à análise estatística, de acordo com as normas do instrumento. Posteriormente, através da técnica dos quadrantes e da análise de coeficiente não paramétrica de Spearman, os dados foram correlacionados, no sentido de verificar possíveis relações entre aspectos da vida cotidiana, sobrecarga e percepção, por parte dos cuidadores, de sua qualidade de vida. Os resultados possibilitaram conhecer que houve mudança, diminuição do convívio social, alteração na vida profissional e estresse na vida do cuidador em decorrência do ato de cuidar. Em relação à qualidade de vida, pôde-se constatar que o domínio meio ambiente apresentou maior satisfação, enquanto que o menor índice ficou com as relações sociais, indicando assim a importância da rede de apoio social para o cuidador. A variável tempo de cuidado indicou que, quanto maior este for, maior a satisfação com relação ao bem-estar psicológico, meio ambiente e relações sociais. Identificaram-se dois tipos de sobrecarga, a velada e a declarada. Conclui-se que o impacto do adoecimento da criança interfere diretamente na vida cotidiana e nas relações dos cuidadores, assim como na qualidade de vida, porém, percebe-se que recursos estruturais e emocionais contribuem para minimizar os efeitos negativos sobre os cuidadores. Neste sentido ressalta-se a importância da equipe multidisciplinar oferecendo amparo informativo, técnico, troca de experiência e suporte aos cuidadores.UCHÔA-FIGUEIREDO, L. R. Disease impact on the daily lives of caretakers of children with Difficult to Control Epilepsy. 2009. 260p. Thesis (PhD) Faculty of Philosophy, Science and Humanities of Ribeirao Preto, University of Sao Paulo, São Paulo, 2009. Acknowledging that a child has a chronic disease throws parents into a crisis related to expectations of a desired idealized descendant. The family is uncertain about disease evolution and possible consequences. However, it is the mother, who as a rule, becomes the main caretaker, helping to supply all necessities but showing a occupational life full of short-comings caused by spent time and physical and emotional energy. Her quality of life is further compromised by the suffered losses and work burden. This study aimed to investigate changes in the daily life of primary caretakers of patients diagnosed with Difficult to Control Child Epilepsy associated to non-evolutive chronic encephalopathy , and to evaluate effects of the overload as a function of disease onset on the quality of life. Perception by caretakers of disturbances in their own quality of life by the emotional burden was also verified. The fifty caretakers evaluated were taking care, for at least two years, of children 7 to 12 years old, from both sexes and with a confirmed diagnosis of five years. The study was approved by the Ethics Committee on Research with Human Beings of the University Hospital, Faculty of Medicine of Ribeirao Preto, University of Sao Paulo (HCFMRP) and was conducted at the Child Epilepsy Service of the same Hospital. Data were obtained through the children medical records, half-structured interviews addressing onset of the disease and daily care, and completion of the overload questionnaires ,Caregiver Burden Scale and Quality of Life, WHOQOL-bref. Data from interviews were analyzed by the Interpretation Quantitative System and the ones from WHOQOL-bref and Caregiver Burden Scale submitted to statistical analysis according to the rules of the instruments. Using the quadrant technique and analysis of the non-parametric Spearman coefficient, the data were further correlated to verify the existence of a relationship between aspects of burdened daily life and perception of their quality of life by caretakers. Results showed that the act of care did produce changes in the life of the caretaker, characterized by decreased socializing , disturbed professional life and stress . Considering quality of life, environmental factors were more satisfying than the ones of social relations, emphasizing the importance of social support in the life of a caretaker. As to the variable related to care duration, the longer it lasted the higher satisfaction in psychological well being, environment and social interchange were achieved . Two types of burdens were identified, one concealed and one declared. It is concluded that onset of disease in children does directly interfere in the daily life and relationships of caretakers, thus in their quality of life. However, by showing the contribution of structural and emotional resources to minimize the negative effects on caretakers, the importance of supportive information, techniques and exchange of experiences provided by a multi-professional team is also emphasized.

Full textAbstract:
A primary algorefinery, concept that deals with the main components of microalgae (lipids, proteins, carbohydrates and pigments), has been studied. A sequence of unit operations has been implemented in order to obtain separated enriched fractions of these biomolecules by conserving their integrity in the downstream process. The study was mainly centred on Chlorella vulgaris, a species known for its rigid cell wall. Most of the lipophilic fraction (lipids and pigments) was recovered using supercritical carbon dioxide with ethanol as a co-solvent, without a preliminary unit operation of cell disruption. The hydrophilic fraction (proteins and polysaccharides) was recovered in the aqueous phase after bed milling as cell disruption method. Subsequently, the aqueous phase was fractionated into three fractions by means of a process of two-stage ultrafiltration. Thus, starches, pigments, proteins and sugars were successfully separated from each other. A life cycle assessment will be necessary to estimate the cost and the sustainability of the fractionation process.

Full textAbstract:
The primary focus of RtI has been at the elementary school level. However, over the past few years there has been a shift, and RtI has been expanding to secondary schools. Through this expansion, it is unclear if RtI has been effectively implemented at the secondary level. The ultimate goal for any school implementing change is institutionalization or sustainability. Therefore, this qualitative case study examined the institutionalization or sustainability of RtI systems in one high school. This study was designed to deepen the understanding of secondary RtI and to add to the literature on RtI at the secondary level. The purpose was to understand how one secondary school addressed the complexity and uniqueness of the secondary environment while sustaining RtI practices. The participants in this study shared several research-based practices that they believed assisted struggling students to become academically successful. The findings regarding RtI practices and implementation were supported by researchers whose works were analyzed in the literature review. The study concluded that understanding the phases of change, the three major forces which influenced change and a clear, well thought out plan are vital components to success.

Full textAbstract:
Auf der Suche nach Determinanten der erfolgreichen beruflichen Integration in den allgemeinen Arbeitsmarkt wurden Teilnehmer einer Integrationsmaßnahme für psychisch beeinträchtigte Menschen bei der REHAaktiv darr GmbH sowohl qualitativ als auch quantitativ untersucht. Es handelt sich um eine prospektive Längsschnitt- bzw. Kohortenstudie. Der umfangreichere Quantitative Teil der Arbeit beinhaltet die Auswertung erhobener demographischer, psychodiagnostischer und persönlicher (Freizeit, finanzielle Situation) Daten von n=206 Maßnahmeteilnehmern bezüglich der Zielvariablen erfolgreiche berufliche Integration direkt nach der Maßnahme, nach einem halben Jahr sowie nach einem Jahr und Abbruch der Maßnahme aus gesundheitlichen Gründen sowie Anzahl krankheitsbedingter Fehlzeiten während der Maßnahmedauer. Als Prädiktoren der erfolgreichen beruflichen Integration konnten ein hohes Intelligenzniveau, ein guter Schulabschluss, das Vorhandensein eines Partners, ein mittleres bis hohes Engagement, gute Kontrollstrategien innerhalb der Stressbewältigung sowie ein höheres Einkommen zu Maßnahmebeginn gefunden werden. Die Einnahme von Medikamenten, ein höheres Alter, eine vorhandene Berufsunfähigkeit sowie eine subjektiv höhere Einschätzung der psychosomatischen Beschwerden wurden als Prädiktoren des Maßnahmeabbruchs aus gesundheitlichen Gründen identifiziert. Die Anzahl krankheitsbedingter Fehlzeiten wurde durch die beiden Prädiktoren psychosomatische Beschwerden sowie das Fehlen der Diagnose Schizophrenie, vorher gesagt. Im zweiten Teil der Arbeit erfolgte die Auswertung der qualitativen Interviews von jeweils sechs erfolgreich integrierten und sechs nicht integrierten Maßnahmeteilnehmern. Als Ergebnis konnten die generellen Bedeutungsschwerpunkte Empfundene Unterstützung durch die Mitarbeiter, fehlende berufliche Orientierung sowie die große Bedeutung der Praktika und der Seminargruppe herausgestellt werden. Individuelle Unterschiede in Bezug auf den Integrationserfolg zeigten sich bezüglich der Bedeutung der Arbeit, der Fähigkeit zur Stressbewältigung, der Selbsteinschätzung und der Einstellung zur Maßnahme.Searching for determinants for the successful integration into the general job market, participants in a rehabilitation program for the mental handicapped carried out by REHAaktiv darr GmbH were studied qualitatively und quantitatively. This was a prospective longitudinal or cohort study. The more extensive, quantitative part of the study consists of an analysis of the demographic, psychodiagnostic and personal (leisure time, financial situation) data ascertained from n=206 participants with regard to the variable objectives of the successful integration immediately after completion of the scheme, after six months and one year as well as after dropping out of the scheme for health reasons as well as the number of days absent for health reasons during the scheme. Predictors of a successful integration are high intelligence, high school graduation, the presence of a partner, a mid to high level of commitment, good strategies of control as soon as a higher income in the beginning of the program. Medication, advanced age, vocational disability and subjectively higher assessment of the psychosomatic troubles were identified as predictors for dropping out of the scheme for health reasons. The number of absences due to illness was predicted by the predictors psychosomatic disorders as well as the absence of a diagnosis schizophrenia. The second part of the study consisted of the assessment of the qualitative interviews with six participants who were successfully integrated and six who were not. The result that emerged emphasized the amount of support from the REHAaktiv personnel “felt” by the participants, a lack of career orientation on their part as well as the great importance of the practical training and the seminar group. Individual differences with respect to the success of the integration could be attributed to the importance of work, the ability to deal with stress and mental attitude to the scheme.

Scalability and high demand for resources are the main challenges that content providers face to deploy Video-on-Demand applications. The most popular site for sharing videos, YouTube, has over 4 billion videos viewed a day and 60 hours of video are uploaded every minute. Hybrid systems (CDN-P2P) have been proposed as a scalable and cost effective solution for VoD distribution. In these systems, peers share their resources decreasing demand on the content distribution network infrastructure (CDN). On the other hand, the CDN s servers guarantee the availability of content when peers contributions are limited by churn. However, in these systems, the content distributed must be managed so that the CDN servers workload is minimized. An issue to be investigated is the impact of churn, i.e the effect of cycle of peers join and leave, on management policies. Carried studies showed that the performance of policies improves as the storage capacity of peers increases. However, this increasement does not impact proportionately the performance of policies. Later on, we proposed, implemented and evaluated four object management policies derived from data in YouTube video collections. These policies use information left by users or generated by the video distribution system to measure the value of objects. We found that the proposed policies were able to improve the availability of content in more than 70%, compared to the LFU policy, and more than 50% compared to GDSP policy.

Full textAbstract:
Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage and Frequency Scaling (DVFS) techniques have proven to be handy in this situation for an efficient trade-off between energy and timely behavior. Within imec, wearable devices make use of the indigenously developed MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). This system is optimized for efficient and accurate collection, processing, and transfer of data from multiple (health) sensors. MUSEIC v2 has limited means in controlling the voltage and frequency dynamically. In this thesis we explore how traditional DVFS techniques can be applied to the MUSEIC v2. Experiments were conducted to find out the optimum power modes to efficiently operate and also to scale up-down the supply voltage and frequency. Considering the overhead caused when switching voltage and frequency, transition analysis was also done. Real-time and non real-time benchmarks were implemented based on these techniques and their performance results were obtained and analyzed. In this process, several state of the art scheduling algorithms and scaling techniques were reviewed in identifying a suitable technique. Using our proposed scaling technique implementation, we have achieved 86.95% power reduction in average, in contrast to the conventional way of the MUSEIC v2 chip’s processor operating at a fixed voltage and frequency. Techniques that include light sleep and deep sleep mode were also studied and implemented, which tested the system’s capability in accommodating Dynamic Power Management (DPM) techniques that can achieve greater benefits. A novel approach for implementing the deep sleep mechanism was also proposed and found that it can obtain up to 71.54% power savings, when compared to a traditional way of executing deep sleep mode.Nuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.

This thesis explores educator beliefs, attitudes and practices in teaching First Nations, Inuit, Métis and Ethnic students in Canada, including Muslim and Arabic students. Research supports evidence of on-going systemic racism toward the First Nations, Métis and Inuit, and New Canadians in society, and therefore, within our schools and our classrooms. Evidence also exists regarding how racism, invisibly instilled in educators as societal norms, permeates classrooms and helps continue to perpetuate marginalization and Othering of students.
The research question was: How can teachers begin to deconstruct Euro-Centric, White Dominant beliefs, practices, attitudes and expectations in order to positively impact all students and their academic well-being?
I examine the questions: What are some teachers doing which positively impacts learning for all students? What can be done to help teachers realize that some of their teaching practices and ways of dealing with students are disrespectful to the individual children and contribute to systemic racism?

Full textAbstract:
The soil-borne, rhizosphere-competent, filamentous fungus Trichoderma virens
is a well-known biocontrol agent able to control pathogenic fungi through the production
of antibiotics, the induction of systemic resistance in host plants, or by directly
parasitizing the competing fungus. Competition for iron is another means by which
Trichoderma can hinder competing microorganisms, and siderophores are a means by
which microorganisms obtain iron. In silico analysis of the T. virens genome suggested
that two genes putatively encoding extracellular siderophore-producing nonribosomal
peptide synthetases (NRPSs) were present.
In this study, a disruption was created in one of the genes, TvNPS6, to create a
mutant unable to produce the NRPS TvNps6 (DeltaTvnps6). Previously, a mutant
(DeltaTvsidD) had been generated with a disruption in the second gene (TvSIDD) encoding
an NRPS thought to be involved in siderophore biosynthesis. A double mutant
(DeltaDeltaTvsidDTvnps6) was generated by transformation of a DeltaTvsidD strain with a vector
targeting disruption of TvNPS6. This resulted in transformants disrupted within both the putative siderophore-producing NRPSs. Thus, three mutants were available for analysis
of the role of these genes in the ecology of T. virens. Transformants were confirmed by
PCR and Southern blotting analysis.
Phenotypic characterization of the mutants included both HPLC analysis of
siderophore production, growth on agar and in liquid media, conidiation, germination in
the presence of hydrogen peroxide, biocontrol against Pythium ultimum, in vitro
confrontation against Rhizoctonia solani and growth with iron chelators to determine the
contribution of reductive iron assimilation (RIA) compared to that of siderophores. The
HPLC analysis demonstrated that T. virens Gv 29-8 (wild-type) produced a single
siderophore peak when grown in an iron-depleted medium. This peak was not present in
the DeltaTvnps6 and DeltaDeltaTvsidDTvnps6 mutants but was apparent with the DeltaTvsidD
mutants. From the HPLC analysis, T. virens evidently produces a coprogen-type
siderophore. Few differences were observed in the other phenotypic tests, though
hydrogen peroxide showed some small inhibitory effects towards the DeltaTvnps6 mutants.
The addition of chelators, which inhibit RIA, exerted some negative effects on all strains
growing under iron-limited media, particularly the DeltaTvnps6 and DeltaDeltaTvsidDTvnps6
strains.
This study demonstrated that although T. virens has two genes putatively
encoding siderophore producing NRPSs, only the TvNPS6 gene was required for
extracellular siderophore production. The greater sensitivity of the mutants towards the
iron chelators suggests that unlike other other fungi studied, Trichoderma virens utilizes RIA, rather than siderophore production, as the primary means by which the fungus
obtains iron in an iron-limited environment.

In this paper, we present a P2P-based database sharing system that provides information sharing capabilities through keyword-based search techniques. Our system requires neither a global schema nor schema mappings between different databases, and our keyword-based search algorithms are robust in the presence of frequent changes in the content and membership of peers. To facilitate data integration, we introduce keyword join operator to combine partial answers containing different keywords into complete answers. We also present an efficient algorithm that optimize the keyword join operations for partial answer integration. Our experimental study on both real and synthetic datasets demonstrates the effectiveness of our algorithms, and the efficiency of the proposed query processing strategies.Singapore-MIT Alliance (SMA)

In 1953 the tangled, skeletal remains of a ship were pulled from the small harbor of
Penetanguishene, Ontario. Local historians had hoped to raise the hull of a War of 1812
veteran, but the vessel pulled from the depths did not meet the criteria. Identified as
H.M. Schooner Tecumseth, the vessel was built just after the War of 1812 had ended.
Historical research of Tecumseth and her sister ship Newash, which remained in
Penetanguishene harbor, illuminated the ships? shadowy past. Conceived and built after
the war, the vessels sailed for only two years before being rendered obsolete by the
terms of the Rush-Bagot disarmament agreement. Nevertheless, the two vessels offer a
unique perspective from which to view the post-war period on the Great Lakes.
The schooners? hulls were interpreted and analyzed using archaeological evidence. A
theoretical rigging reconstruction was created, using contemporary texts and
documentary evidence of the ships themselves. Architectural hull analysis was carried
out to explore the nature of these vessels. From these varied approaches, a conception of Newash and Tecumseth has emerged, revealing ways in which the hulls were designed to
fulfill their specific duties. The hulls were sharp, yet had capacious cargo areas. The
rigs combined square-rigged and fore-and-aft sails for maximum flexibility. The designs
of the hulls and rigging also reflect predominant attitudes of the period, in which naval
vessels on the lakes gave way to merchant craft.
Taken as a whole, Tecumseth and Newash illustrate how ships, while fluid in the nature
of their work, are also singular entities that truly encapsulate a specific point in time and
place.

Full textAbstract:
Η αύξηση της διαθέσιμης Πληροφορίας στον Παγκόσμιο Ιστό είναι ραγδαία. Η παρατήρηση αυτή παρότρυνε πολλούς ερευνητές να επικεντρώσουν το έργο τους στην εξαγωγή χρήσιμων γνωρισμάτων από διαδικτυακά έγγραφα, όπως ιστοσελίδες, εικόνες, βίντεο, με σκοπό τη ενίσχυση της διαδικασίας κατηγοριοποίησης ιστοσελίδων. Ένας πόρος που περιέχει πληροφορία και δεν έχει διερευνηθεί διεξοδικά για γλώσσες εκτός της αγγλικής, είναι η διεύθυνση ιστοσελίδας (URL- Uniform Recourse Locator). Το κίνητρο της διπλωματικής αυτής εργασίας είναι το γεγονός ότι ένα σημαντικό υποσύνολο των χρηστών του διαδικτύου δείχνει ενδιαφέρον για δικτυακούς πόρους, των οποίων οι διευθύνσεις URL περιλαμβάνουν όρους προερχόμενους από τη μητρική τους γλώσσα (η οποία δεν είναι η αγγλική), γραμμένους με λατινικούς χαρακτήρες. Προτείνεται μέθοδος η οποία θα αναγνωρίζει και θα εξάγει τις λέξεις-κλειδιά από διευθύνσεις ιστοσελίδων (URLs), εστιάζοντας στο ελληνικό Διαδίκτυο και συγκεκριμένα σε URLs που περιέχουν ελληνικούς όρους. Το κύριο ζήτημα της προτεινόμενης μεθόδου είναι ότι οι ελληνικές λέξεις μπορούν να μεταγλωττίζονται με λατινικούς χαρακτήρες σύμφωνα με πολλούς διαφορετικούς τρόπους, καθώς και το γεγονός ότι τα URLs μπορούν να περιέχουν περισσότερες της μιας λέξεις χωρίς κάποιο διαχωριστικό. Παρόλη την ύπαρξη προηγούμενων προσεγγίσεων για την επεξεργασία ελληνικού διαδικτυακού περιεχομένου, όπως αναζητήσεις στο ελληνικό διαδίκτυο και αναγνώριση οντότητας σε ελληνικές ιστοσελίδες, καμία από τις παραπάνω δεν βασίζεται σε διευθύνσεις URL. Επιπλέον, έχουν αναπτυχθεί πολλές τεχνικές για την κατηγοριοποίηση ιστοσελίδων με βάση κυρίως τις διευθύνσεις URL, αλλά καμία δεν διερευνά την περίπτωση του ελληνικού διαδικτύου. Η προτεινόμενη μέθοδος περιέχει δύο βασικά στοιχεία: το μεταγλωττιστή και τον κατακερματιστή. Ο μεταγλωττιστής, βασισμένος σε ένα ελληνικό λεξικό και ένα σύνολο κανόνων, μετατρέπει τις λέξεις που είναι γραμμένες με λατινικούς χαρακτήρες σε ελληνικούς όρους ενώ παράλληλα ο κατακερματιστής τμηματοποιεί τη διεύθυνση URL σε λέξεις με νόημα, εξάγοντας, έτσι τελικά ελληνικούς όρους που αποτελούν λέξεις κλειδιά. Η πειραματική αξιολόγηση της προτεινόμενης μεθόδου σε δείγμα ελληνικών URLs αποδεικνύει ότι μπορεί να αξιοποιηθεί εποικοδομητικά στην αυτόματη αναγνώριση λέξεων-κλειδιών σε ελληνικά URLs.The available information on the WWW is increasing rapidly. This observation has triggered many researchers to focus their work on extracting useful features from web documents that would enhance the task of web classification. A quite informative resource that has not been thoroughly explored for languages other than English, is the uniform recourse locator (URL). Motivated by the fact that a significant part of the Web users is interested in web resources, whose URLs contain terms from their non English native languages,written using Latin characters, we propose a method that identifies and extracts successfully keywords within URLs focusing on the Greek Web and especially ons URLs, containing Greek terms. The main issue of this approach is that Greek words can be transliterated to Latin characters in many different ways based on how the words are pronounced rather than on how they are written. Although there are previous attempts on similar issues, like Greek web searches and entity recognition in Greek Web Pages, none of them is based on URLs. In addition, there are many techniques on web page categorization based mainly on URLs but noone explores the case of Greek terms. The proposed method uses a three-step approach; firstly, a normalized URL is divided into its basic components, according to URI protocol (scheme :// host / path-elements / document . extension). The domain part is splitted on the apperance of punctuation marks or numbers. Secondly, domain-tokens are segmented into meaningful tokens using a set of transliteration rules and a Greek dictionary. Finally, in order to identify useful keywords, a score is assigned to each extracted keyword based on its length and whether the word is nested in another word. The algorithm is evaluated on a random sample of 1,000 URLs collected manually. We perform a human-based evaluation comparing the keywords extracted automatically with the keywords extracted manually when no other additional information than the URL is available. The results look promising.

Annotation The diploma thesis deals with the description and analysis of tax and administrative management in terms of deadlines. The aim of the thesis is to find a practical basis when applying an inconsistent setting of deadlines in the tax and administrative procedures. It was important to determine whether the concept of deadlines in the legislation is different, how the concept of time is regulated in the legislation and how this issue can actually affect us. The analysis of individual management was based on actual data. I was provided the data related to the tax procedure by a particular tax subject. The data related to the administrative procedure were requested from a specific administrative authority. The practical part of the thesis deals with a detailed analysis of individual management in terms of deadlines. The tax procedure was about determining the preclusion of the deadline for a tax assessment and the identification of the factors which had an impact on the course of this period. In the case of administrative proceeding, the time limits which are necessary for discussion of the minor offense and the administrative offense were analyzed. The thesis contains tables with data for better clarity within individual management.

Os Corpos de Bombeiros (CB) contam com uma rede de quartéis implantada em todo o território nacional, atualmente organizada por um modelo baseado nos limites territoriais das NUTS (Nomenclatura das Unidades Territoriais para Fins Estatísticos). Será, portanto, possível rentabilizar a rede de CB no patamar sub-regional, através da implementação de critérios de desempenho dos CB, entre eles, a população abrangida dentro dos tempos de resposta convencionados.
O objetivo deste trabalho é propor uma reorganização operacional da rede de quartéis já implantada nas Sub-Regiões da Lezíria do Tejo e Médio Tejo, tendo como base um modelo da Rede Principal dos Serviços Operacionais dos Corpos de Bombeiros em Portugal Continental. Para tal, definiram-se critérios com vista à constituição de Agrupamentos de CB, que partilhando entre si áreas de atuação, permite priorizar o despacho de meios baseado no tempo de resposta dentro dos limites dos Agrupamentos. A aplicação dos critérios contemplando a rede viária existente e a distribuição da população residente, permitiu, recorrendo ao software QGIS®, aferir as zonas com necessidade de reforço da rede de quartéis.
Aplicado o modelo à área de estudo, verificou-se um aumento de 18,4% (1.401 km2) de área e de 6,1% da população (30.524 habitantes) abrangidas dentro dos tempos de referência (10 e 20 minutos). Para garantir a atividade operacional nos 24 municípios abrangidos, a rede de CB contaria 24 quartéis sede e 22 postos avançados (reforço da atual rede com 8), guarnecidos no mínimo por um efetivo total de 1.897 bombeiros profissionais.
O facto da rede de quartéis já se encontrar implantada no território alvo de estudo e apenas necessitar de reforços pontuais, deveria ser atualmente um fator desencadeador de interesse na sua rentabilização por parte das várias entidades envolvidas.Fire Departments (CB) have a network of barracks deployed throughout the national territory, currently organized by a model based on the territorial limits of the NUTS (Nomenclature of Territorial Units for Statistical Purposes). Therefore, it will be possible to improve the fire department network at the sub-regional level, through the implementation of fire departments performance criteria, including the population coverage within the settled response times. The objective of this work is to propose an operational reorganization of the barracks network already implemented in the Sub-Regions of Lezíria do Tejo and Médio Tejo, based on a model of the Main Network of Operational Services for Fire Brigades in Mainland Portugal. To this end, criteria were defined with a view to the constitution of CB Groups, which sharing areas of activity among themselves, allows prioritizing the dispatch of means based on the response time within the limits of the Groups. The application of the criteria covering the existing road network and the distribution of the resident population, allowed, using the QGIS® software, to assess the areas in need of reinforcement of the barracks network. Applying the model to the Lezíria do Tejo and Médio Tejo sub-regions, there was an increase of 18,4% (1.401 km2) in area and 6,1% of the population (30.524 inhabitants) covered within the reference times (10 and 20 minutes). In order to guarantee operational activity in the 24 municipalities covered, the fire departments network would consist of a total of 24 headquarters and 22 outposts with a minimum of 1.897 professional firefighters. The fact that the barracks network is already implanted in the study target territory and only needs occasional reinforcements, should be a triggering factor of interest in its profitability by the various entities involved.

In the following thesis we studied the development of performance motivation of pupils and its possible mutual connection with external evaluation according to relation norms. In the theoretical part we deal with scientific solutions of terms as performance motivation and relation norm. Mainly we concentrate on the analysis of the so called process model of performance motivation and on the analysis of types of relation norms. We also investigate in detail the issues of genesis of fear and anxiety of individuals during performance activities. We also occupy ourselves with the issues of causal attributions and different perspectives of term range of internal and external motivation. Subsequently, we made causal links between theoretical solutions and school performance. In this part we refer in particular to works of Heckhausen and Rheinberg. In the practical part we present a research, which is focused on the search for links between the use of individual relation norms in pedagogical situations of a teaching lesson and the development of performance motivation of pupils. In the research we took advantage of combination of quantitative and qualitative investigation. Triangulation of these methods helped us to understand better the contemporary school reality and to obtain relatively clear and...
