The cohesion factor: / a study of Japanese junior high school writing

Coombe, Deneys Laurence January 2015 (has links)
This study compared cohesive devices in texts written by Japanese second-year junior high school learners with those in texts that appeared in the textbook they were studying. The purpose of the study was to determine which cohesive devices were being used in the textbook and which were used in the learners’ writing. The study used both quantitative and qualitative analysis. The quantitative analysis began by determining whether there was any significant difference between the textbook readings and the learners’ writing in terms of the frequency of cohesive devices. It then examined the kinds of devices that were used by both groups of texts. The qualitative analysis compared the patterns of reiteration in two textbook readings with those in a sample of six student texts of different levels of success. The results showed no significant differences between the student texts and the textbooks in terms of the overall frequency of cohesive devices. Among the individual devices, however, there was a significantly higher frequency of ellipsis and synonyms in the textbook readings than in the student texts. There was also a significantly higher frequency of conjunction and reference in the student texts relative to the textbook readings. In all other devices, there was no significant difference between the textbook readings and the student texts. The qualitative study revealed the importance of strong opening sentences, reinforcement of the main topic through repetition, as well as of linking new topics with the main topic in the textbook readings. However, the presence of these features varied in the selected student texts. Accordingly, stronger texts contained all these features, average texts contained some of them, and weaker texts contained few or none. This study consequently supports other studies that have shown that the way in which cohesive devices are used is far more important in determining text quality than the number of devices used. The findings of this study showed the strengths and weaknesses in the students’ writing, and highlighted the need for a greater awareness of cohesion by focusing more on sentence building, and the use of a greater variety of cohesive devices / English Studies

Sliding stability re-assessment of concrete dams with bonded concrete-rock interfaces

Krounis, Alexandra January 2016 (has links)
The shear strength of the concrete-rock interface is an important parameter in sliding stability analyses of concrete dams founded on rock and depends, in addition to the normal stress state, on the bonding conditions of the interface; concrete-rock interfaces can be either unbonded, partially bonded or fully bonded. In the Swedish guidelines for dam safety all dam-foundation contacts are treated as unbonded. This has the benefit of eliminating all uncertainties related to the cohesive strength of bonded contacts but it might also lead to unnecessary strengthening of dams. Other national guidelines deal with the uncertainties related to cohesion by applying higher safety factors, mainly determined based on previous experience, when both cohesion and friction are taken into account. The main objective of this project is to study if and how cohesion can be included when evaluating the shear strength of bonded or partially bonded interfaces. To accomplish this, uncertainties associated with cohesion are identified and their influence on the assessed stability is investigated. The results show that the influence on the assessed sliding stability is strongly dependent on the magnitude of the involved uncertainties that might vary significantly for different dams. It is thus questionable if one safety factor applicable for all dams can be established for use in deterministic analyses. Taking into account cohesion when reliability methods are used is somewhat less complicated because of the possibility of directly incorporating the uncertainties in the analysis. The main challenge in such cases is the quantification of the involved uncertainties due to lack of proper data and, in some cases, knowledge. In this thesis, a framework for quantification of parameter uncertainty is suggested and the model error due to brittle failure in combination with spatial variation in cohesion is analysed. Areas that require more research to further refine the analysis are also identified. / Skjuvhållfastheten i betong-berggränssnittet är en avgörande faktor vid glidstabilitetsutvärderingar av befintliga betongdammar grundlagda på berg och beror dels på normalspänningsfördelningen och dels på kontaktytans status med avseende på vidhäftning, vilken kan delas in i tre separata fall; då vidhäftning existerar och kohesion medräknas (intakt), då vidhäftning aldrig funnits eller förlorats (bruten), samt en kombination av föregående (delvis intakt). I RIDAS, de svenska riktlinjerna för dammsäkerhet, behandlas alla berg-betonggränssnitt som brutna. Detta förhållningssätt har fördelen att det utelämnar all osäkerhet förknippad med intakta kontaktytors kohesion men det kan också resultera i icke nödvändiga förstärkningar av dammar. I andra nationella riktlinjer för dammsäkerhet beaktas osäkerheterna förknippade med kohesion genom att högre säkerhetsfaktorer, i huvudsak bestämda baserat på erfarenhet, tillämpas då både kohesion och friktion används vid beräkning av kontaktytans skjuvhållfasthet. Det övergripande syftet med detta doktorandprojekt är att studera om och hur kohesion kan medräknas vid stabilitetsutvärderingar av befintliga betongdammar med helt eller delvis intakta betong-berggränssnitt. För att uppnå detta, identifieras osäkerheter förknippande med kohesionen och deras inverkan på den bedömda glidstabiliteten utvärderas. Resultaten från projektet visar att osäkerheternas inverkan på den uppskattade glidstabiliteten är starkt beroende av osäkerheternas storlek, vilken varierar för olika dammar. Det är således tveksamt om en säkerhetsfaktor giltig för alla dammar kan bestämmas för användning i deterministiska stabilitetsanalyser. När sannolikhetsbaserade metoder används kan osäkerheterna införlivas direkt i analysen. Kvantifieringen av osäkerheterna förknippade med ett specifikt fall utgör då den huvudsakliga utmaningen. I denna avhandling presenteras ett ramverk för att uppskatta de statistiska parametrarna hos de ingående variablerna. Dessutom studeras modellosäkerheten förknippad med intakta gränssnitts spröda brott i kombination med kohesionens rumsliga variation i detalj. Områden som fordrar ytterligare forskning i syfte att förbättra analysen identifieras också. / <p>QC 20160411</p>

An Analysis of Interreg Projects across Europe : A critical examination on the role of networks and the implementation of EU concepts

Donnabháin, Ian O, Röpcke, Julian January 2007 (has links)
An Analysis of Interreg Projects across Europe A critical examination on the role of networks and the implementation of EU concepts The intention of this thesis project was to get a deeper insight into the effect the European Union can have in the regions of Europe, in particular through the workings of the Interreg program. From study the theoretical concepts, we wished to discover how these concepts were practically implemented through different projects and partnerships. Due to the informal nature of the European Union spatial planning, we also wished to understand the importance that networks play in the projects and the effect they have on the activities of the project partnerships. We decided that the best way to study this subject was through a comparison of two contrasting projects in different parts of Europe but that deal with similar concepts. The theoretical perspective we took to approaching the subject matter, was to include much of the theory and ideas on the workings of networks and the potential results they can bring. In particularly we focused upon networks in the context of the transfer of knowledge, and their importance for creating the environment for such transfer to occur, and the many elements that can support or hinder .Furthermore we looked at much of the theory behind the concepts that the EU promotes, such as Sustainability, the different models that can be followed, as well the suggested conflict between Cohesion and Competitiveness. For the comparison we chose two contrasting projects; - BalticMaster Interreg IIIB based in Karlskrona, Sweden, involving 40 partners - EARD Interreg IIIC based in Brandenburg, Germany, involving 10 partners Both projects were established under the intention of Sustainable Development in their respective regions. One based on protecting the Baltic Sea from oil spillages, and the second aimed at sustainable development of regions around airports. The comparisons in terms of networks were quite striking; one the one hand, BalticMaster was largely based on pre-existing networks between the different regions of the Baltic Sea and had an emphasis on partner interaction. On the other hand, EARD was a brand new project partnership with no history of collaboration between the regions and interaction of the partners was rare. In terms of EU concepts, there were similarities as both projects took a bottom up approach to the broad concepts and connected this concepts to their work and aims in different ways to make them relevant. Interestingly, those project participants that were interviewed shared a lack of understanding of some the concepts before undertaking the project, some by their own admission, even though it was the main theme of their project. Conclusions that could be drawn from the work included the interaction of concepts and networks, and how each can affect each other. EU concepts can form new partnerships and networks because common goals can be shared in new partnership under the broad concepts. Furthermore, strong networks can assist the concrete implementation of these broad concepts and assist in the understanding of these concepts across the project partnership. In conclusion, we can see that there are many advantages to the flexibility of the EU broad concepts and how Interreg allows them to be interpreted, but there are also many problems in trying to insure that what is funded by Interreg is faithful to the intent of those broad concepts. The challenge is how to strike a balance between the necessary flexibility and insuring the outcomes are in line with the intent.

STUDYING SOFTWARE QUALITY USING TOPIC MODELS

Chen, TSE-HSUN 14 January 2013 (has links)
Software is an integral part of our everyday lives, and hence the quality of software is very important. However, improving and maintaining high software quality is a difficult task, and a significant amount of resources is spent on fixing software defects. Previous studies have studied software quality using various measurable aspects of software, such as code size and code change history. Nevertheless, these metrics do not consider all possible factors that are related to defects. For instance, while lines of code may be a good general measure for defects, a large file responsible for simple I/O tasks is likely to have fewer defects than a small file responsible for complicated compiler implementation details. In this thesis, we address this issue by considering the conceptual concerns (or features). We use a statistical topic modelling approach to approximate the conceptual concerns as topics. We then use topics to study software quality along two dimensions: code quality and code testedness. We perform our studies using three versions of four large real-world software systems: Mylyn, Eclipse, Firefox, and NetBeans. Our proposed topic metrics help improve the defect explanatory power (i.e., fitness of the regression model) of traditional static and historical metrics by 4–314%. We compare one of our metrics, which measures the cohesion of files, with other topic-based cohesion and coupling metrics in the literature and find that our metric gives the greatest improvement in explaining defects over traditional software quality metrics (i.e., lines of code) by 8–55%. We then study how we can use topics to help improve the testing processes. By training on previous releases of the subject systems, we can predict not well-tested topics that are defect prone in future releases with a precision and recall of 0.77 and 0.75, respectively. We can map these topics back to files and help allocate code inspection and testing resources. We show that our approach outperforms traditional prediction-based resource allocation approaches in terms of saving testing and code inspection efforts. The results of our studies show that topics can be used to study software quality and support traditional quality assurance approaches. / Thesis (Master, Computing) -- Queen's University, 2013-01-08 10:10:37.878

The social impact of a flood on workers at a Pretoria hotel / E. Milella

Milella, Elisabetta January 2012 (has links)
In South Africa, January 2011 was characterised by above average rainfall which resulted in many provinces being flooded. On the 17th of January 2011, the government of South Africa declared the City of Tshwane a National Disaster Area. It is in the city of Tshwane where a hotel was flooded causing great damage and disruption to the lives of the hotel workers. Given the lack of existing research focusing on the social dimensions of natural disasters, this provided an opportunity to study the social impact of the flood on the community of hotel workers at a Pretoria hotel. Four sub-aims were set for the study, which involved an exploration of the strengths that were exhibited, discovered or developed as a result of the flood; investigating the subjective experiences in relation to the flood; exploring the interactional patterns and relationships of the hotel workers; as well as investigating how the leadership of the hotel impacted on the manner in which the hotel workers dealt with the flood. A qualitative methodology, guided by a social constructivist epistemology was adopted as basis for the study. Data was gathered by means of individual semi-structured interviews, semi-structured questionnaires, and a focus group interview with a number of employees at the hotel. The data was subjected to qualitative content and grounded theoretical analysis. Five main themes emerged from the analysis, which include: Emotional responses, which included negative emotions such as shock, fear, frustration and anger, as well as positive emotions such as happiness and appreciation; a variety of interactional patterns and relationships; increased cohesiveness; enhanced leadership, and the development of group resilience. / MA, Medical Sociology, North-West University, Vaal Triangle Campus, 2012

Discrete element modelling of iron ore pellets to include the effects of moisture and fines

Morrissey, John Paul January 2013 (has links)
Across industry the majority of raw materials handled are particulate in nature, ranging in size and properties from aggregates to powders. The stress regimes experienced by the granular solids vary and the exhibited bulk behaviours can be complex and unexpected. The prevalence of granular solids makes them an area of interest for industry and researchers alike as many challenges still remain, such as dealing with complex cohesive behaviour in materials, which often gives rise to handling difficulties. Storage and transportation are an important part of the process chain for industries where particulate solids are commonplace. Failure to properly account for the cohesive nature of a particulate solid can be costly as it can easily lead to blockages in a silo such as ratholing or arching near the outlet during discharge. The cohesive strength of a bulk material depends on the consolidation stress it has experienced. As a result, the stress history in the material leading up to a handling scenario needs to be considered when evaluating its handling behaviour. The Discrete Element Method (DEM) has been extensively used to simulate the behaviour of granular materials, however the majority of the focus has been on noncohesive systems. For cohesive solids, it is crucial that the stress history dependent behaviour is adequately captured. Many of the contact models commonly used in DEM simulations to simulate cohesive granular materials such as the JKR model or liquid bridge models are elastic in nature and may not capture the stress history dependent behaviour observed in cohesive particulate solids. A comprehensive study on the effect of cohesion arising from the addition of moisture on the behaviour of two types of LKAB iron ore fines (KPBO and KPRS) has been carried out. The addition of moisture to the sample has been found to have a significant effect on both kinds of fines. KPRS fines were found to have a much higher unconfined strength and flow function at higher moisture contents, and also show a greater increase in cohesion with the addition of moisture, while at moisture contents of less than 2% the KPBO fines demonstrate higher unconfined yield strength. The KPBO fines were also found to achieve a significantly looser initial packing at much lower moisture content when compared to the KPRS fines. The lateral pressure ratio has also been evaluated. In this study a mesoscopic adhesive contact model that accounts for contact plasticity and stress history dependency in the bulk solid, the Edinburgh Elasto-Plastic Adhesion (EEPA) mode, has been presented and mathematically verified. A parametric study of the DEM contact model parameters was conducted to gain a deeper understating of the effect of input parameters on the simulated cohesive bulk behaviour. The EEPA contact model has been used to predict an experimental flow function of KPRS iron ore fines. The contact model has demonstrated the ability to capture the stress history dependent behaviour that exists in cohesive granular solids. The DEM simulations provide a very close match to the experimental flow functions, with the predicted unconfined strengths found to be within the standard deviations of the experimental results. Investigations into the failure mode predicted by the DEM simulations show that the samples are failing from the development of shear planes similar to those observed experimentally. The effect of increasing levels of adhesion has been explored for a flat bottomed silo where the level of adhesion has been varied. The DEM simulations were found to capture the major phenomena occurring in silo discharge including the various flow zones associated with a flat bottomed silo. Funnel flow, the effective transition and mass flow which are associated with a mixed flow pattern were observed in the model silo. The location of the effective transition height was identified: above this was mass flow. The velocity determined from the discharge rate was found to be in excellent agreement with the velocity profiles found in the zones of mass flow. A high velocity core flow zone was observed above the outlet where velocities were greater than 1.25 times the mass flow velocity, VMF. The level of adhesion in the silo was found to affect the discharge rate - a reduced flow rate was found until the eventual blockage of the silo at a high level of adhesion was found. As the level of adhesion increased the probability of arching also increased, and the formation of intermittent arching behaviour was noted in the cases with higher levels of adhesion in the system. The development of both temporary and permanent cohesive arches over the silo outlet were also observed with stopped flow from the silo.

Social Cohesion as a Gateway: Examining France's Efforts in Building Equitable Education Access for Marginalized Immigrants

Molezion, Cherish 01 January 2017 (has links)
This thesis examines the effects of France’s educational social cohesion policies, Zones d’Education Prioritaire (ZEP schools) and L’Agence nationale pour la cohesion sociale et l’égalité des chances (Acsé). I argue that these policies affect access to education for working-class descendants of immigrants; however, France’s republican ideology inhibits the extent to which equitability can be established between working-class descendants of immigrants and the majority population. Though a quantitative and qualitative data analysis, I scrutinize trends in education access and the labor market over the 2000s. Lastly, I make policy recommendations centering around positive discrimination approaches that France should adopt, in order to prioritize its most marginalized population.
