Spatial and temporal patterns of plankton in European coastal waters : analysis and comparison of zooplankton time series / Variations spatiales et temporelles du plancton dans les eaux côtières européennes : analyse et comparaison de séries temporelles de zooplancton

Eloire, Damien 09 July 2010 (has links)
Le changement climatique est incontestable et affecte les océans. L'observation à long terme d'indicateurs comme le plancton peut permettre l'étude de ces changements. Le suivi du plancton dans les eaux côtières d'Europe représente une source de données importante actuellement sous-exploitée et sur laquelle cette étude est basée. Des outils analytiques ont d'abord été conçus pour résoudre des divergences taxonomiques entre les données et pour réaliser l'analyse temporelle. L'étude du plancton à L4 de 1998 à 2007 révèle de profonds changements dans la composition phytoplanctonique des blooms de printemps et d'automne, et des variations à long terme dans l'abondance des taxa dominants du zooplancton. Le phytoplancton gouverne la succession saisonnière des larves méroplanctoniques. Les changements de température de surface et de vent contrôlent les variations temporelles des communautés planctoniques. Les variations spatio-temporelles du zooplancton ont été comparées à 4 sites de 1998 à 2007 : Ston (Mer du Nord), L4 (Manche), MC (Mer Tyrrhénienne ), et C1 (Mer Adriatique). La structure des communautés est globalement stable, la saisonnalité étant la principale source de variabilité à long terme. La chlorophylle a et le vent expliquent les variations de la communauté zooplanctonique à Ston et L4 alors que c'est la température à MC et C1. Cette étude confirme l'extrême adaptabilité des communautés zooplanctoniques à un environnement variable. Elle souligne l'importance de facteurs tels que taxonomie et échelle temporelle pour l'analyse de séries, et la nécessité de maintenir les séries à long terme pour le suivi de futurs changements dans le contexte du changement climatique. / Climate change is unequivocal and dramatic changes are under way in the world's oceans. Long-term observations of indicators such as plankton can provide a better understanding of these changes. Considerable efforts have been made to monitor plankton in European coastal waters and have produced a large amount of datasets yet to be fully exploited. Analytic tools were first developed to solve taxonomic discrepancies in datasets and for temporal analyses. Time series analysis of plankton at L4 from 1988 to 2007 reveals profound changes in the composition of the spring and autumn phytoplankton blooms, and long-term variations in abundance of the dominant zooplankton taxa. Phytoplankton is driving the seasonal succession of meroplanktonic larvae. Changes in sea surface temperature and wind conditions control temporal patterns of plankton communities. Spatio-temporal patterns of zooplankton are compared at 4 sites: Ston (northern North Sea), L4 (wes tern English Channel), MC (Tyrrhenian Sea), and C1 (Adriatic Sea) from 1998 to 2007. The communities structure is on average stable and seasonal variations are the main source of long-term variability. Chlorophyll a and wind are responsible for the community patterns observed at Ston and L4 whereas temperature is the main driver at MC and C1. This study supports evidences of the extreme flexibility of zooplankton communities in adjusting to a variable environment. We highlighted the importance of factors such as taxonomy and temporal scale on time series analysis, and the necessity of maintaining long-term series to monitor future changes in the context of climate change.

A Comparative Analysis of State Funds on Student Achievement of Economically Disadvantaged Elementary Schools in Independent School Districts and Charter Schools in the State of Texas

Applewhite, Gary 05 1900 (has links)
The purpose of this study was to evaluate the relationship between the instructional outcomes in the independent school districts and charter schools in relation to the expenditure of public funds for instruction and total operating expenditures from the general fund. The study considered Texas elementary charter schools and independent school districts, whose school populations were identified as having greater than or equal to 50% of economically disadvantaged students, according to the Texas Academic Excellence Indicator System (AEIS). The study made use of multiple regression and was an ex post facto cross-sectional analysis utilizing production function theory. The study’s outcomes reported the difference in student achievement between elementary schools in independent public school districts and charter schools were small to negligible for math and reading achievement. The study also reported, there is no statistically significant difference in per pupil expenditure of public funds between elementary schools in independent public school districts and charter schools. Furthermore, there is no statistically significant relationship between student achievement and per pupil expenditure of public funds on elementary schools in independent public school districts and charter schools.

A Rural vs. Urban Analysis of Procedures Provided to Medicaid Recipients by Pediatric, General, and Public Health Dentists in the Commonwealth of Virginia: Fiscal Years 1994-1995

Pettinato, Frank Carmen 01 January 2003 (has links)
Purpose: The purpose of this study was to report the distribution of procedures provided to Virginia Medicaid children by three types of dental providers in rural and urban areas. Methods: Medicaid claims filed for dental patients younger than 21 were obtained and analyzed for fiscal years 1994 and 1995. Dental providers were categorized according to their practice type: general practice (GP), pediatric (PD) and public health (PH) dentists. Each type of practice was categorized as practicing in a Metropolitan, Urban, Rural or Completely Rural location and evaluated for percentages of preventive, diagnostic, and corrective services provided.Results: The number of procedures was shown to differ depending upon: year, practice type, location, significant provider status, and the type of procedure.Conclusion: General, pediatric and public health dentists in Metropolitan and Urban areas perform slightly more diagnostic services and much less corrective services than practitioners in more rural areas.

Mediální obraz USA ve zpravodajství ČTK v komparaci se zpravodajstvím korespondenta ČRo v první polovině roku 2013 / A media picture of USA by ČTK and its comparison with ČRo reporter's news in the first half of the year 2013

Veitová, Kateřina January 2015 (has links)
The diploma thesis A Media Picture of USA by ČTK and its Comparison with ČRo Reporter's News in the First Half of the Year 2013 focuses on the comparison of the news and materials released by Czech Press Agency, Czech Radio and its foreign correspondent, about United States. Using qualitative and quantitative methods the paper examines the extent of the space donated to the topics related to USA, which themes were followed and how every of the subjects were informing on them. The quantitative methods are used when analyzing the news releases by Czech Press Agency and coverage of Czech Radio including contributions of foreign correspondent, during the period of the first six months of 2013. The qualitative part analyzes the way in which subjects reported on two selected events in the United States - attacks on the Marathon in Boston and West Fertilizer Company explosion. Other parts of this work are chapters focusing on the theory of foreign news and the position of USA.

K problematice překladu povídky Groza Vladimira Nabokova / On the translation of The Thunderstorm by Vladimir Nabokov

Hušek, Jan January 2015 (has links)
The diploma thesis offers an analysis of a unique set of texts. The analysis explores the language devices used in the composition of the texts. The set of texts includes a short story Groza by Vladimir Nabokov and its translations. The short story was originally written in Russian, and then translated by the author into English. There exist two Czech translations, one from Russian, one from English. The thesis presents a theoretical framework for the analysis. It is composed of two parts. The first one summarizes the most frequent translation related changes in meaning. The second one compares Nabokov's theory and practice of translation. The theoretical framework is applied to the comparison of the target-language texts with the source-language texts, as well as to the comparison of the two translations from different source-language texts. Comparison of the results of the analysis with the hypotheses stated in the Introduction affirms the movement of the meaning towards stylistic neutrality and shows the influence of the source-language upon the target-language. On the other hand it rejects the statement that Nabokov as a self-translator wanted to preserve the literary qualities of the text, being ready to sacrifice its language qualities. Keywords: comparative analysis, language devices,...

Le choix d'un système de transport durable : analyse comparative des systèmes de transport guidé de surface / The choice of a sustainable transportation system : comparative analysis of surface guided transportation systems

An, Jeong-Hwa 11 April 2011 (has links)
Le choix d'un système de transport guidé de surface exploité en site propre (TCSP) est un travail complexe et difficile. Les différents systèmes peuvent sembler offrir des services équivalents pour les utilisateurs tandis que manquent souvent les informations nécessaires pour mieux distinguer les différences entre tel ou tel système. L'objectif de cette recherche vise, au-delà d'une présentation des différents systèmes guidés de surface qui structurent les réseaux de transport public en France, à procéder à une analyse comparative afin de mieux guider les choix des collectivités territoriales, dans le contexte des efforts qu'elles conduisent pour promouvoir des transports urbains répondant aux enjeux du développement durable. Les avantages et points faibles de chaque système est analysé et présenté de manière désagrégée. De manière complémentaire, est proposée et discutée une méthode multicritère ELECTRE III permettant d'agréger les résultats obtenus et de proposer le (ou les) système(s) le(s) mieux adapté(s) à différents contextes d'exploitation. Le résultat principal met en évidence le fait que le tramway moderne sur fer occupe une place privilégiée dans la majorité des scenarii. Cependant, le CIVIS, le Translohr, TVR et même le trolleybus ont leur place selon le contexte d'exploitation, dès lors en particulier que sont pris en compte les coûts d'infrastructure et d'exploitation associés. Les résultats de cette recherche nous encouragent en outre à recommander, chaque fois qu'il y a un projet de système de transport de surface, de passer en revue la gamme des systèmes et d'effectuer l'analyse comparative avec les différentes contraintes du lieu et du moment, en y intégrant une vision de moyen et long terme et les effets prévisibles sur l'aménagement urbain / The choice of a guided surface transit system operated on separated RoW is a complex and difficult task. Even if different transit systems could provide equivalent services to users, we often lack the necessary information to better distinguish among different systems. Beyond giving a presentation of different surface guided systems structuring the public transport networks in France, the aim of this research is to conduct a comparative analysis in order to better guide decisions of local authorities in their efforts to promote urban transport that meets the challenges of sustainable development. The advantages and the drawbacks of each system are analyzed and presented in a disaggregated way. In addition, a multicriteria method ELECTRE III is proposed and discussed for aggregating the results and proposing system(s) best suited for different operating conditions. The main result shows that the modern tramway on rail occupies a privileged place in most scenarios. However, the CIVIS, Translohr, TVR and even trolleybuses have their places with respect to operating conditions, given that the related infrastructure and operating costs are taken into account. The results of this research therefore encourage us to recommend, every time we propose a surface transit system, to review the whole range of systems and to do the comparative analysis with different context and time constraints integrating mid-term and long-term visions and predictable effects on the urban requalification

Komparativní analýza veřejné sféry na internetu a v tištěných médiích / Public sphere in printed media and on Internet: comparative analysis

Čížková, Lucie January 2013 (has links)
This thesis presents an analysis of the public sphere in the environment of two different media types. The analysis is performed on the basis of the extent of different participants in the media contents which were related to the declaration of the ban on selling alcohol spirits in the Czech Republic in September 2012. The theoretical part of the paper is focused primarily on the definition of the basic concepts, such as new and traditional media, the public and the public sphere, then also on normative theories in general, along with a more detailed view on the normative theory of the public sphere, within which the paper is focused on participatory and discursive model of Jürgen Habermas. The second part of the paper provides on the basis of quantitative research, which was preceded by qualitative analysis, an empirical comparison of the extent of different participants and their access to the content of both media types. It also provides an overview of applied topics and contextual frameworks through which was a declaration of the ban on selling alcohol spirits in the media reported. In the conclusion, there is a statement which is based on the evaluation of the collected data. It was concluded, that the public sphere in the internet environment is not, considering the extent of participation of...

Srovnání definovaných subjektů v tanečním oboru / Comparison of the defined subjects in the dance field

Machová, Veronika January 2013 (has links)
Title: Comparison of defined subjects on the dance field Objectives: The main target of this thesis is creation of analyses of two dance groups from Czech Republic, specifically Paul-Dance Jilemnice and Enliven Centre, followed by mutual comparison and creation of set of recommendations to help improve their further work. Methods: In this thesis I used the internal analysis, PEST analysis and comparative analysis, on whose basis I created SWOT analyses of both dance groups, thanks to which I suggested possible recommendations. Results: This thesis brings information about their current situation to both dance groups, points out the shortages and recommends steps for improvement. Both groups have been affected by worldwide economic crisis, which caused not only loss of members, but also loss of sponsors. Moreover, Paul-Dance collects low membership fees, which ensure stable flow of finance to the budget; Enliven Centre does not have all individual age categories filled. Keywords: associations, dance, dance group, internal analysis, PEST analysis, comparative analysis, SWOT analysis

Det öppna samhället ekar ihåligt #gränskontroller : En komparativ diskursanalys om och hur medier samverkar i diskurser kring flyktingfrågan / The echos in the open society #gränskontroller : A comparative discourseanalysis if and how media co-work in discourses about refugees.

Magnusson, Agnes, Jönsson, Hanna January 2017 (has links)
Studiens syfte är bidra med kunskap om likheter och skillnader mellan diskurser kring flyktingfrågan i traditionella medier och på Twitter genom att undersöka språkanvändningen samt explicita teman utifrån diskurser i tidningarna Dagens Nyheter och Svenska Dagbladet samt i tweets på Twitter. Studien vill att få kännedom om och hur de traditionella mediernas diskurser samverkar med diskurser på Twitter. För att uppnå syftet med studien bryts syftet ned i fyra frågeställningar: vilka retoriska stilfigurer används i Dagens Nyheter, Svenska Dagbladet och på  Twitter utifrån den valda problematiken? Vilka manifesta och latenta budskap går att urskilja med hjälp av språket i Dagens Nyheter, Svenska Dagbladet och på Twitter?  Vilka negativa respektive positiva värdeladdade ord förekommer i Dagens Nyheter, Svenska Dagbladet och på Twitter? Hur kan den visade språkanvändningen diskuteras utifrån diskursteori och dagordningsteori? Studiens teoretiska ramverk utgår från diskursteori och dagordningsteori samt kopplas samman med tidigare forskning i analysen. Studiens resultat visar att gestaltningen av flyktingfrågan manifesteras på olika vis genom språkanvändningen, till exempel i användningen av retoriska stilfigurer och värdeladdade ord. Twitters språkanvändning är mer dramatisk och kritik uttrycks mer explicit i jämförelse med språkanvändningen i Dagens Nyheter och Svenska Dagbladet. Studien visar dock en möjlig samverkan mellan de båda medierna, då liknande teman hittades i respektive medier. Det var svårare att urskilja manifesta och latenta budskap i diskurserna på Twitter i jämförelse med diskurserna i Dagens Nyheter och Svenska Dagbladet. De båda medierna subjektställer de svenska aktörerna medan flyktingar återfinns som objekt eller inte alls förekommer. Resultatet visar att det i den aktuella studien, finns en samverkan mellan dagspress och social medier. Dagspressens ämnen återfinns i diskurserna på Twitter, där Twitteranvändare tycker något om ämnet dagspressen tar upp. / The purpose of this study is to contribute to knowledge about similarities and differences between discourses in traditional- and social media concerning the refugee issue. Furthermore the purpose will be answered by exploring and compare the use of language and explicit themes in the discourses, in two of Swedens largest newspapers: Dagens Nyheter and Svenska Dagbladet, aswell as selected top-tweets on Twitter. The intention of the study is to receive understanding if and how the discourses in traditional media are reciprocating with the discourses on Twitter. To fufill the purpose of this study, four framing questions will be answered: which rhetorical stylistic figures are used in Dagens Nyheter, Svenska dagbladet and on Twitter? Which explicit and implicit messages can be discovered with help from the used language in the discourses in Dagens nyheter, Svenska dagbladet and Twitter? What negative respectively positive emotive words occurs in the newspapers and on Twitter? How can the result of the used language be discussed by Discourse theory and The agenda setting theory? The study’s theoretical framework are The agenda setting theory and Discourses theory, the theories will be connected to previous research about representation in the media in the section of analysis. The study’s result shows that the figuration of the refugee issue are displayed in different ways through the use of language, for example in the use of rhetorical stylistic figures and emotionally charged words. The used language on Twitter contains more explicit negative and dramatically charged words compared to discourses in Dagens Nyheter and Svenska Dagbladet. However the study indicated a cooperation between the traditional- and social media, due to similar themes that were discovered. Nevertheless, it was more difficult to distinguish the explicit and implicit messages in the discourses on Twitter compared to Dagens Nyheter and Svenska Dagbladet. The subjects in the newspapers where rediscovered on Twitter, where users consider something about the subject which shows some tendencies of collaboration between the newspapers and social media.

Sydafrikas och Sveriges läroplan i ett bedömningssystem : En jämförelse om de olika sätten att bedöma barn på - ett dilemma / South Africa's and Sweden's curriculum in an assessment system : A comparison of the different ways of judging children - a dilemma

Lindahl, Therese January 2019 (has links)
This is a comparative study based on text analysis of South Africa's and Sweden's curriculum. The purpose of the study is to get an understanding and awareness of the meaning and content of the curricula concerning child assessment. Its focus is to find out about similarities and differences of the assessment and evaluation processes. My research questions are: • What do South Africa's and Sweden's curricula for learning outcomes the children are assessed on? • How is South Africa's and Sweden's assessment of children described individually and evaluation in the curriculum? • What similarities and differences are there in South Africa's and Sweden's curriculum on the assessment of children individually and evaluation on the preschool?   The methods I use are qualitative text analysis and comparative analysis. I analyze and compare words and contents. My findings are that the assessment is about a way to see the children's development and learning. By having a conscious way of looking at children's interest and not to assess and judge individually which can lead to harming them. Instead, assess and judge as to benefiting the child to get support and can develop her/himself and her/his learning. Pedagogical documentation is used from the Swedish curriculum to see the children's interest and development. In South Africa notebook is used for documentation. The South African curriculum has more content with tips on development opportunities. If we compare the Swedish curriculum, there are learning outcomes where the goals are not as specified as the South African curriculum. This means that the Swedish curriculum has space for interpretation. In this study, we can gain an understanding of assessment in preschool and gain clarity of the dilemma that exists. / Studien handlar om att jämföra och göra en textanalys på Sydafrikas och Sveriges läroplan. Mitt syfte är att ta reda på vad som står i läroplanerna för att få förståelse och medvetenhet av de olika sätten att bedöma barn på. Detta för att ta reda på likheter och skillnader i processerna för bedömning och utvärdering. De frågeställningar jag har är: • Vad har Sydafrikas och Sveriges läroplaner för lärandemål där barnen blir bedömda på? • Hur beskrivs Sydafrikas och Sveriges bedömning av barn individuellt och utvärdering i läroplanen? • Vilka likheter och skillnader finns det i Sydafrikas och Sveriges läroplan om bedömning av barn individuellt och utvärdering på verksamheten?   De metoder jag använder mig av är kvalitativ textanalys och jämförande analys där jag analyserar och jämför ord och innehåll. Mina resultat var att bedömning handlar om ett sätt att se barnens utveckling och lärande. Genom att ha ett medvetet sätt att se på barns intresse och att inte bedöma barnen där det kan genom att bedöma individuellt leda till men för barnet. I stället bedöma där det gynnar barnet för att få stöd att utveckla sig själv och sitt lärande. Pedagogisk dokumentation använder den svenska läroplanen för att se barns intresse och utveckling. Sydafrika använder sig av att notera i anteckningsbok. Den sydafrikanska läroplanen har mer innehåll med tips på utvecklingsmöjligheter. Om vi jämför den svenska läroplanen finns det lärandemål där målen inte är lika specificerade som den sydafrikanska läroplanen. Detta gör att den svenska läroplanen har tolkningsutrymme. Genom denna studie kan vi få förståelse för bedömning i förskola och få klarhet i dilemmat som finns.
