This is a case study in which it is carried out an analysis of PIBID-Biology subproject of the Federal University of São Carlos (UFSCar), which is part of PIBID UFSCar-institutional project. From an analysis of all documents relating to the implementation of the project at all levels (national, institutional and subproject) as well as the interview with researchers involved in the construction of these projects, we built a description of the processes involving the construction of the national project, as well as the institutional design and, finally, the subproject Biology UFSCar. This first step was the context for understanding, through analysis of reflective portfolios produced by scholars, the dimensions of teaching knowledge built by undergraduates as scholarship students from PIBID. In light of the training teacher references (NÓVOA, 2009; ANDRÉ, 2012, GATTI, BARRETTO & ANDRÉ 2011, Zeichner, 2010, among others), knowledge of the teachers (PEPPER, 2005 Tardif, 2000, 2007) and also Complexity Theory (BONIL & PUJOL, 2008; RIBERAYGUA, 2012; MORIN, 2004, 2005), we realized that, despite the PIBID have characteristics that approach a complex and dynamic model, students have many difficulties in view their performance as part of a complex system that involves not only the classroom but the entire surroundings. We understand that this may occur because not always the PIBID works in coordination with the context , undermining thus functioning as a dynamic and complex system , requiring several adjustments and improvements in this program. / Este trabalho insere-se no âmbito das investigações sobre a formação inicial de professores, investigando o Programa Institucional de Bolsas de Iniciação à Docência. Trata-se de um estudo de caso em que é realizada uma análise do subprojeto PIBID-Biologia da Universidade Federal de São Carlos (UFSCar), que se insere no projeto institucional PIBID-UFSCar. A partir de uma análise de todos os documentos referentes à implementação do projeto em todos os âmbitos (nacional, institucional e subprojeto), bem como da entrevista com pesquisadores envolvidos na construção destes projetos, construímos uma descrição dos processos envolvendo a construção do projeto nacional, bem como do projeto institucional e, finalmente, do subprojeto Biologia da UFSCar. Esta primeira etapa constituiu o contexto para compreendermos, através da análise dos portfólios reflexivos produzidos pelos bolsistas, as dimensões de saberes docentes construídos pelos licenciandos enquanto bolsistas do PIBID. À luz dos referenciais de formação docente (NÓVOA, 2009; ANDRÉ, 2012, GATTI, BARRETTO & ANDRÉ, 2011, ZEICHNER, 2010, dentre outros), de saberes docentes (PIMENTA, 2005, TARDIF, 2000, 2007) e também da Teoria da Complexidade (BONIL & PUJOL, 2008; RIBERAYGUA, 2012; MORIN, 2004, 2005), percebemos que, apesar de o PIBID possuir características que o aproximam de um modelo complexo e dinâmico, os bolsistas apresentam muitas dificuldades em visualizar a sua atuação como parte de um sistema complexo, que envolve não apenas a sala de aula, mas todo entorno. Entendemos que isto pode ocorrer porque nem sempre o PIBID funciona de maneira articulada com o contexto, o que prejudica, portanto, o seu funcionamento como um sistema dinâmico e complexo, sendo necessários diversos ajustes e melhorias neste Programa.

No. of bitstreams: 1 arquivototal.pdf: 1282793 bytes, checksum: 89108643134dc04656635868546c5b16 (MD5) Previous issue date: 2011-08-23 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This study addresses the importance of the planning process for tourism systems respecting your organization systemic and complex logic. Therefore, relied on three major concepts: A Systems Theory / Complexity Theory, Operations Management and Tourism Planning. Through theoretical discussions, we sought to show that tourism is a complex system and therefore its development needs to be planned. As an alternative to both, we constructed a frame of reference based on six models of pre-existing tourism planning and objectives of Planning, Programming and Production Control (PPPC). The frame of reference proposed contextualizes the goals of PPPCs in the environment of tourism, showing that it is possible to extend the activities of the operations management environments more complex, taking into account new challenges to Production Engineering. / Este estudo aborda a importância do processo de planejamento para os sistemas turísticos, buscando respeitar a sua organização sistêmica e a lógica complexa. Para tanto, apoiou-se em três grandes conceitos: A Teoria de Sistemas/Teoria da Complexidade, a Gestão de Operações e o Planejamento Turístico. Por meio de discussões teóricas, buscou-se mostrar que o turismo é um sistema complexo e que por isso o seu desenvolvimento precisa ser planejado. Como alternativa para tanto, foi construída uma estrutura de referência com base em seis modelos de planejamento turístico pré-existentes e nos objetivos do Planejamento, Programação e Controle da Produção (PPCP). A estrutura de referência proposta contextualiza os objetivos do PPCP no ambiente do turismo, mostrando que é possível estender as atividades da Gestão de Operações a ambientes mais complexos, atendendo aos novos desafios impostos à Engenharia de Produção.

A emergência da competência oral como sistema dinâmico, adaptativo e complexo no ensino-aprendizagem de inglês como língua adicional para iniciantes / The emergence of oral competence as a dynamic adaptive and complex system in english learning-teaching for beginners

Lesliê Vieira Mulico 20 February 2013 (has links)
No âmbito do ensino-aprendizagem de línguas adicionais, pesquisas acerca do desenvolvimento da oralidade têm demonstrado que se trata de um fenômeno multidimensional. Nakatani (2010) mostrou que o domínio de estratégias comunicacionais são indicadores de desempenho linguístico e se relacionam com a proficiência do aprendiz; Kang, Rubin e Pickering (2010) observaram que os traços fonológicos afetam a percepção sobre inteligibilidade e proficiência; Hewitt e Stephenson (2011), e Ahmadian (2012) indicaram que as condições psicológicas individuais interferem na qualidade da produção oral. Escribano (2004) sugeriu que a referência contextual é essencial na construção de sentido; Gao (2011) apontou os benefícios do ensino baseado na construção do sentido, a partir de metáforas conceptuais (LAKOFF e JOHNSON, 1980), codificação dupla (CLARK e PAIVIO, 1991) e esquemas imagéticos (LAKOFF, 1987); e Ellis e Ferreira-Junior (2009) demonstraram que as construções exibem efeitos de recência e priming, afetando o uso da linguagem dos parceiros interacionais. Tais estudos apontam para a natureza complexa da aquisição de L2, mas o fazem dentro do paradigma experimental da psicolinguística. Já Larsen-Freeman (2006), demonstra que a fluência, a precisão e a complexidade desenvolvem-se com o tempo, com alto grau de variabilidade, dentro do paradigma da Teoria da Complexidade. Em viés semelhante, Paiva (2011) observa que os sistemas de Aquisição de Segunda Língua (ASL) são auto-organizáveis. Esses trabalhos, no entanto, não abordaram aprendizes de L2 com proficiência inicial, como pretendo fazer aqui. Tendo como referenciais teóricos a Teoria da Complexidade e a Linguística Cognitiva, o presente trabalho apresenta um estudo de caso, qualitativo-interpretativista, com nuances quantitativos, que discute os processos de adaptação que emergiram na expressão oral de um grupo de aprendizes iniciantes de inglês como língua adicional no contexto vocacional. Parte do entendimento de que na sala de aula vários (sub)sistemas complexos coocorrem, covariando e coadaptando-se em diferentes níveis. A investigação contou com dados transcritos de três avaliações coletados ao longo de 28 horas de aula, no domínio ENTREVISTA DE EMPREGO. Após observar a produção oral das aprendizes, criei uma taxonomia para categorizar as adaptações que ocorreram na sintaxe, semântica, fonologia e pragmática da língua-alvo. Posteriormente organizei as categorias em níveis de prototipicidade (ROSCH et al, 1976) de acordo com as adaptações mais frequentes. Finalmente, avaliei a inteligibilidade de cada elocução, classificando-as em três níveis. A partir desses dados, descrevi como a prática oral dessas participantes emergiu e se desenvolveu ao longo das 28 horas. Os achados comprovam uma das premissas da Linguística Cognitiva ao mostrarem que os níveis de descrição linguística funcionam conjuntamente em prol do sucesso comunicacional. Além disso, demonstram que a função do professor, como discutem LARSEN-FREEMAN e CAMERON (2008), não é gerar uniformidade, mas sim oportunizar vivências que estabeleçam continuidade entre o mundo, o corpo e a mente / In the field of second and foreign language learning, research on oral communication development has been demonstrating that it is a multi-dimensional phenomenon. Nakatani (2010) showed that the ability to use communicative strategies is related to linguistic performance and learners proficiency level; Kang, Rubin and Pickering (2010) affirmed that learners phonology affects perception over proficiency and intelligiblity; Hewitt and Stephenson (2011), as well as Ahmadian (2012), contended that individual psychological conditions interfere in the quality of production. Escribano (2004) suggested that contextual knowledge is essential to conceptualization; Gao (2011) pointed out the benefits of an approach based on conceptual metaphors (LAKOFF and JOHNSON, 1980), dual coding (CLARK and PAIVIO, 1991), and image schemas (LAKOFF, 1987); Ellis and Ferreira-Junior (2009) demonstrated that constructions exhibit priming and recency effects, which influence participants language use. These studies together instantiate the complex nature of L2 acquisition on the experimental psychology paradigm. In the scope of Complexity Theory, Larsen-Freeman (2006) demontrated that fluency, accuracy, and complexity increase over time, despite exhibiting high individual variability. By the same token, Paiva (2011) observed that SLA systems are self-organisable. Nevertheless, none of the above-mentioned studies addressed beginners, as we intend to do herein. By overlapping Complexity Theory and Cognitive Linguistics, we present a case study, with sprinkles of quantification, in order to specifically discuss the adaptation processes that emerged from the oral practice of a group of six English beginner female learners (n=6) in the vocational context. We understand that several complex (sub-) systems co-occur in the classroom, covarying and coadapting in different levels. The investigation counted on transcribed data (ATKINSON and HERITAGE, 1984) from three oral evaluations collected over 28 class hours, in the JOB INTERVIEW domain. After observing the learnersoral production, we created a taxonomy to categorise the adaptations that emerged in target language syntax, meaning, fonology and pragmatics. Later, we displayed the categories in prototype levels (ROSCH et al, 1976) in terms of frequency. Finally, we classified the inteligibility of each learners utterance in three levels. By means of these data, we were able to describe how participants oral expression emerged and evolved over 28 hours. The results reaffirm one of Cognitive Linguistics premises when showing that language description levels work jointly in favor of communicative success; and demonstrate that the teacher, rather than generate uniformity, ought to give rise to learning opportunities that provides a continuum between the world, the body and the mind, as discussed by Larsen-Freeman e Cameron (2008)

Processo de desenvolvimento das inovações na cadeia produtiva da maçã brasileira

Cruz, Marcia Rohr da 19 September 2013 (has links)
A inovação exerce importância no negócio das empresas, compreende diferentes aspectos e contribui de formas diversas para o seu crescimento e desenvolvimento. Dentre os aspectos que podem ser levados em consideração para as inovações estão os aspectos internos relacionados com o contexto da organização e os aspectos externos que envolvem todo o ambiente em que a organização está inserida. Acredita-se que estes aspectos exercem influência tanto na decisão para o desenvolvimento das inovações quanto para a aplicação dos produtos ou processos de inovação no mercado. Este estudo teve como objetivo identificar como e porque as inovações emergem na cadeia produtiva da maçã brasileira e quais os resultados obtidos a partir das inovações implementadas nos segmentos produtores e packinghouses. Os procedimentos metodológicos empregados têm como estratégia de pesquisa o estudo de caso, o qual foi efetivado através das abordagens qualitativa e quantitativa de pesquisa. Em relação aos objetivos o estudo teve caráter exploratório, descritivo e explicativo. A etapa qualitativa foi executada através da pesquisa exploratória com especialistas da cadeia produtiva da maçã brasileira para identificar as inovações que foram implementadas e também para classificá-las de acordo com o encadeamento do anel tetralógico. Dentre os principais resultados obtidos ressalta-se a identificação dos aspectos que compuseram o framework e serviram de norteador para a realização da pesquisa qualitativa. Destaca-se também o encadeamento obtido entre os aspectos identificados de forma empírica e a junção com as teorias utilizadas, em especial os pressupostos de Edgar Morin, através da teoria da complexidade. A etapa quantitativa foi efetivada através do método estatístico, por meio da análise fatorial, cuja análise apresentou a identificação dos resultados que as inovações apresentam para os fatores sociais, econômicos, organizacionais, políticos e mercadológicos na amostra de produtores e packing-houses da cadeia produtiva da maçã brasileira definidas para esta investigação. Na análise quantitativa merece destaque a apresentação através de estatística descritiva da caracterização das amostras, bem como os processos de inovação que cada amostra tem implementado. A análise fatorial permitiu a apresentação das variáveis destacadas para cada fator nas quatro amostras (produtores e packing-houses de Santa Catariana e Rio Grande do Sul) individualmente e também para toda a cadeia incluindo as quatro amostras. Através da análise de regressão múltipla identificou-se a percepção sobre o impacto das inovações para toda cadeia produtiva da maçã brasileira, incluindo os produtores e packing-houses dos estados de Santa Catarina e Rio Grande do Sul. / Innovation plays importance in business enterprises, comprises different aspects and contributes in different ways to their growth and development. Among the aspects that can be considered for the innovations are the internal aspects related to the context of the organization and external aspects that involve the whole environment in which the organization operates. It is believed that these aspects influence both the decision for the development of innovations in the application for product or process innovation in the market. This study aimed to identify how and why innovations emerge in the productive chain of Brazilian apples and what the results obtained from the innovations implemented in the sectors producing and packing houses. The methodological procedures have employed as a research strategy case study, which was effected by means of qualitative and quantitative approaches to research. In relation to the objectives the study had an exploratory, descriptive and explanatory. The qualitative analysis was performed through exploratory research with experts in the productive chain of Brazilian apples to identify innovations that have been implemented and also to classify them according to the chain ring tetralogical. Among the main results emphasize the identification of aspects that compose the framework and provided a guideline for conducting qualitative research. Also noteworthy is the chain obtained among those identified empirically and the junction with the theories used, in particular the assumptions of Edgar Morin, by complexity theory. The quantitative stage was effected through the statistical method, by means of factor analysis, which analysis showed identification results show that the innovations to the social, economic, organizational, political and market in the sample of producers and packing-houses of the production chain Brazilian apple defined for this investigation. The quantitative analysis deserves the presentation through descriptive statistics of the characterization of the samples, as well as the processes of innovation that each sample has implemented. A factor analysis of the presentation highlighted variables for each factor in the four samples (producers and packing houses of Santa Catarina and Rio Grande do Sul) individually and for the entire chain including the four samples. Through multiple regression analysis identified the perception of the impact of innovations for the entire production chain of Brazilian apples, including growers and packing houses in the states of Santa Catarina and Rio Grande do Sul.

The effect of systemic functional linguistics-based self-intervention programme on the ESL grammar proficiency of Grade 8 learners

Nell, Karin 01 1900 (has links)
Abstracts in English, Afrikaans and Xhosa / English proficiency is regarded important for economic empowerment in South Africa, since English is the official business language of the country. South Africa is, however, a multilingual country, with 11 official languages. The majority of South African learners do not speak English as first language, but study English as an additional language in school. This leads to English Second Language (ESL) classroom complexities such as multilingualism, negative attitudes to ESL, and various levels of linguistic proficiency, which affect the teaching of the prescribed curriculum. Many learners arrive in secondary school (Grade 8) with underdeveloped English proficiency, which means that a lot of time in ESL classrooms is spent on re-teaching English language concepts, especially grammar concepts. This causes stress for both ESL teachers and learners. This study tested the effectiveness of a self-help ESL grammar intervention programme in order to establish whether existing gaps in grammar knowledge could be closed via self-study outside of the classroom. More specifically, the study asked the question whether learners’ knowledge of Parts of Speech could be enhanced via a self-help intervention programme, which was based on the principles of Systemic Functional Grammar (SFG). SFG is not traditionally used as an instructional framework in ESL classrooms in the South African context. The rationale for assessing the efficiency of an SFG self-help intervention programme was that there is currently a dire need for alternative approaches to teaching ESL grammar, which would assist struggling learners to raise their proficiency levels quickly, and which would allow teachers to continue with the prescribed curriculum. The intervention programme was tested in a controlled quasi-experimental study, which included an experimental group and a control group, and which compared performance in the mid-year examination and year-end examination to performance in a baseline assessment. The results of the study showed that the self-intervention programme was effective in enhancing ESL learners’ knowledge of Parts of Speech, and also had a positive effect on other aspects of grammar knowledge and on writing. Based on these findings, it is recommended that self-regulation and self-instruction be considered for inclusion in ESL syllabi in the South African context, as it can play a positive role in enhancing ESL learners’ linguistic proficiency. / Engelse taalvaardigheid word as belangrik beskou vir ekonomiese bemagtiging in Suid–Afrika, aangesien Engels die offisiële besigheidstaal van die land is. Suid-Afrika het egter elf erkende offisiële landstale en is dus ‘n meertalige land. Die oorgrote meerderheid Suid-Afrikaanse leerders se eerste taal is nie Engels nie, en hierdie leerders neem Engels as tweede taal (ook genoem eerste addisionnele taal) in ‘n formele omgewing op skool. Dit veroorsaak verskeie uitdagings in Engelse tweedetaalklasse, onder andere meertalige leerders, ‘n negatiewe houding teenoor Engels, en oneweredige ontwikkelingsvlakke in Engels. ‘n Groot aantal leerders begin hul sekondêre skoolloopbaan met onderontwikkelde vaardighede in Engels, met name in grammatika. Dit beïnvloed die onderrig van die voorgeskrewe Engelse tweedetaal kurrikulum, veral in Graad 8. Onderwysers is dikwels genoodsaak om baie tyd aan die heronderrig van grammatikale konsepte te spandeer, alvorens die voorgeskrewe Graad 8 kurrikulum hervat kan word. Dit plaas spanning op sowel onderwysers as leerders. Die doel van hierdie studie was om die effektiwiteit van ‘n self-onderrig intervensieprogram te toets – meer spesifiek om te toets of kennisgapings in “Parts of Speech (POS)” oorbrug kan word met ‘n self-onderrig program wat gebaseer is op Sistemiese Funksionele Linguistiek (SFL). SFL word nie tradisioneel in die Suid-Afrikaanse leerprogram gebruik nie, en die rasionaal vir die toetsing van ‘n SFL program was dat daar tans ‘n geweldige vraag is na alternatiewe benaderings tot die onderrig van Engels, wat leerders sal ondersteun om hulle vaardigheidsvlakke snel te verbeter, sodat onderwysers kan voorgaan met die voorgeskrewe kurrikulum. Die SFL intervensieprogram in hierdie studie is deur middel van ‘n gekontroleerde kwasi-eksperimentele metode getoets, wat ‘n eksperimentele groep en ‘n kontrolegroep ingesluit het. Die twee groepe se kennis van woordsoorte is in die middeljaar, asook die eindjaareksamen gemeet, en vergelyk met die resultate van ‘n basislyntoets wat aan die begin van die jaar afgeneem is. Die resultate het bevestig dat die SFL intervensieprogram ‘n positiewe effek gehad het op kennis van woordsoorte. Verdere positiewe effekte was merkbaar in ander aspekte van Engelse grammatika en in skryfvaardigheid. Na aanleiding van hierdie bevindinge is die aanbeveling van hierdie studie dat selfonderrig and self-regulasie oorweeg moet word as belangrike komponente van die Engels tweedetaal sillabus in die Suid-Afrikaanse konteks, aangesien dit ‘n positiewe rol kan speel in die verbetering van Engels tweedetaal leerders se taalvaardigheid. / Ubugcisa kulwimi lwesiNgesi bubaluleke kakhulu ekuxhobiseni ezoqoqosho eMzantsi Afrika kuba silulwimi lwezoshishino olusemthethweni kweli lizwe. Naxa kunjalo uMzantsi Afrika lilizwe elineelwimi ezininzi, apho ezili-11 zamiliselwa njengeelwimi ezisemthethweni. Uninzi lwabafundi baseMzantsi Afrika alusithethi njengolwimi lokuqala isiNgesi, koko lusifunda njengolwimi olongeziweyo esikolweni. Oku kukhokelela kwiingxaki ezininzi kwiklasi efundisa isiNgesi njengoLwimi lwesiBini, ezifana nokusetyenziswa kweelwimi ezininzi kwakunye namanqanaba awohlukileyo olwazi nobugcisa bokusebenzisa ulwimi, nto ezo zichaphazela ukufundiswa kwekharityhulam esekiweyo. Abafundi abaninzi bafika kwisikolo sasesekondari (iBanga lesi-8) bengenalwazi nabugcisa baneleyo besiNgesi, ngenxa yoko, kwiklasi yesiNgesi uLwimi lwesiBini kuchithwa ixesha elininzi kuphindaphindwa ukufundiswa kwesigama sesiNgesi, ngakumbi isigama segrama. Esi sifundo sophando siye sahlola ukusebenza kwenkqubo yongenelelo kufundiso lwegrama yesiNgesi uLwimi lwesiBini apho umfundi azinceda ngokwakhe, ukuze kufunyaniswe ukuba zingavaleka na ezi zikhewu zikhoyo zokuswela ulwazi lwegrama ngokuzifundela ngaphandle kweklasi. Olu phando lujolise ngakumbi kumbuzo wokuba, ingaba ulwazi lwabafundi ngeziGaba zeNtetho lungaphuculwa na ngokusebenzisa le nkqubo yongenelelo yokuzinceda esekelwe kwimithetho-siseko yeSystemic Functional Grammar (iSFG). ISFG ayisetyenziswa ngokwesithethe njengesakhelo sokufundisa kwiklasi yesiNgesi uLwimi lwesiBini eMzantsi Afrika. Esona sizathu sokuvavanya ukusebenza kwale nkqubo yongenelelo yokuzinceda yeSFG, kukuba kukho intswelo enkulu yeendlela ezizezinye zokufundisa igrama yesiNgesi uLwimi lwesiBini, nto leyo inokunceda abafundi abatsala nzima baphucule amaqondo abo obugcisa, kananjalo incede ootitshala bakwazi ukuqhubela phambili nekharityhulam emiselweyo. Le nkqubo yongenelelo yavavanywa kuphando oluphantsi kolawulo olwaziwa ngokuba sisifundo sophando olungagqibelelanga (quasi experimental study), olwaquka iqela lolingelo kunye neqela elisetyenziswa njengomgangatho wentelekiso (control group). Olu phando lwathelekisa indlela abaqhuba ngayo abafundi kwiimviwo zombindi wonyaka nezokuphela konyaka, ithelekiswa kunye nenkqubo yabafundi kuvavanyo olusisiseko. Iziphumo zophando zabonisa ukuba inkqubo yongenelelo yokuzinceda ibe nempumelelo ekuphuliseni ulwazi lwabafundi lweziGaba zeNtetho kwaye ibe nefuthe elakhayo nakweminye imiba yolwazi lwegrama nesakhono sokubhala. Ngokwezi ziphumo kucetyiswa ukuba kuqwalaselwe ukuzilawula nokuzifundisa kwabafundi njengenxalenye yesilabhasi yesiNgesi uLwimi lwesiBini ngokwemeko yaseMzantsi Afrika njengoko oku kuya kuba nefuthe elakhayo ekuphuhliseni ubugcisa babafundi bolwimi lwesiNgesi uLwimi lwesiBini. / Linguistics and Modern Languages / D.

Robin Hood och Hemtjänsten : En förstudie om Företagshälsovårdens arbete med arbetsmiljöfrågor inom hemtjänstbranschen / Robin Hood and the Home Maker Service : A preliminary study on the occupational health service work with health and safety issues in the home maker service industry

Sandberg, Karin January 2014 (has links)
Occupational Health Service (OHS) has an important role in society. It is designed to prevent illness and strengthen the health of workers. OHS operations and development are currently being studied at the School of Technology and Health at the Royal Institute of Technology in Sweden. One of the industries studied is the home maker service. During the 2010s were such employees one of the most ill groups in Sweden. This master's thesis in occupational environment development and change management focus on examining the special knowledge an OHS and its clients in one home maker service need to strengthen the workers of the industry and find out how the interaction between OHS and home maker service works and how it could be evolved. A qualitative study was conducted in a Swedish city on the basis of an organizational perspective. Six persons between 30 and 65 years of age were interviewed. The interviewed people’s occupations were ergonomist, safety engineer, home health aides and managers from both companies. To gain a deeper understanding of the phenomenon the interviews were transcribed. Key themes for the interviewees were collaboration, economy and engagement, important health and safety issues, prevention, the home help service needs of OHS and what support OHS need in their work with the home maker services. The studied parties agreed that they had no developed cooperation and that there was a gap between them. All interviewees consisted on the work environment problems in the industry. These were stress, time pressure, heavy physical work, patients’ homes were not always suited for the home health aides, lack of colleagues, intimidation and violence and smoking patients. There was found a barrier between the preventive work that could be undertaken and what was ordered from the home maker service. / Företagshälsovården (FHV) har en betydelsefull roll i samhället. Den finns till för att förebygga ohälsa och stärka hälsan hos arbetstagare. Företagshälsovårdens verksamhet och utveckling studeras just nu på skolan för teknik och hälsa på Kungliga Tekniska Högskolan. En av de branscher som åskådliggörs är hemtjänsten. Under 00-talet var arbetstagarna i hemtjänsten en av de mest sjukskrivna grupperna i Sverige. Det här magister-examensarbetet inom arbetsmiljöutveckling och förändringsledning fokuserar på att undersöka vilken specialkunskap FHV behöver för att stärka hemtjänstbranschens arbetstagare samt ta reda på hur samverkan mellan FHV och hemtjänsten fungerar och hur den kan utvecklas. En kvalitativ intervjustudie utfördes i en svensk storstad med utgångspunkt i ett organisationsperspektiv. Sex personer mellan 30 och 65 år intervjuades. Intervjuobjektens yrken var ergonom, arbetsmiljöingenjör, undersköterska i hemtjänsten och chefer från båda parter. För att få en djupare förståelse för fenomenet transkriberades intervjuerna. Betydelsefulla gemensamma teman för intervjupersonerna var samverkan, ekonomi och engagemang, viktiga arbetsmiljöfrågor, förebyggande arbete i dag, hemtjänstens tjänstebehov av FHV och vilket stöd FHV behöver i sitt arbete med hemtjänsten.   De studerade parterna var överens om att de inte hade något utvecklat samarbete och att det bestod ett glapp mellan dem. Alla intervjupersoner var eniga om arbetsmiljöproblemen i branschen. Dessa var stress, tidspress, tungt fysisk arbete, att brukarnas hem inte alltid var anpassade för hemtjänstpersonalen, avsaknad av kollegor, hot och våld samt rökande brukare. Det fanns idag en barriär mellan det förebyggande arbete som skulle kunna bedrivas och vad som beställdes av hemtjänsten. / "Nyttiggörande av branschkunskap – implementering av nätverk” med projektledare Annika Vänje

Design optimal des réseaux Fiber To The Home / Optimal design of Fiber To The Home networks

Angilella, Vincent 16 June 2018 (has links)
Pour les opérateurs, les réseaux FTTH représentent à la fois la solution de référence pour répondre à la demande croissante de trafic fixe, et un investissement considérable dû à leur mise en place. Le but de ces travaux est d'assurer le déploiement de réseaux de qualité à moindre coût. Nous commençons à présenter les différents aspects de la planification de ces réseaux qui en font un problème complexe. La littérature concernée est abordée afin d'exhiber les nouveaux défis que nous relevons. Puis nous élaborons des stratégies permettant de trouver la meilleure solution dans différents contextes. Plusieurs politiques de maintenance ou d'utilisation du génie civil sont ainsi explorées. Les problèmes rencontrés sont analysés à la lumière de divers outils d'optimisation (programmation entière, inégalités valides, programmation dynamique, approximations, complexités, inapproximabilité...) que nous utilisons et développons selon nos besoins. Les solutions proposées ont été testées et validées sur des instances réelles, et ont pour but d'être utilisées par Orange / For operators, FTTH networks are the most widespread solution to the increasing traffic demand. Their layout requires a huge investment. The aim of this work is to ensure a cost effective deployment of quality networks. We start by presenting aspects of this network design problem which make it a complex problem. The related literature is reviewed to highlight the novel issues that we solve. Then, we elaborate strategies to find the best solution in different contexts. Several policies regarding maintenance or civil engineering use will be investigated. The problems encountered are tackled using several combinatorial optimization tools (integer programming, valid inequalities, dynamic programming, approximations, complexity theory, inapproximability…) which will be developed according to our needs. The proposed solutions were tested and validated on real-life instances, and are meant to be implemented in a network planning tool from Orange

Konsten att odla konst och kultur genom stads- och samhällsplanering : en studie om att skapa bördiga förhållanden för kulturell infrastruktur / The art of cultivating art and culture through urban and regional planning : a study on how to create fertile conditions for cultural infrastructure

Lundgren, Lovisa January 2018 (has links)
Trots att kulturens roll för hållbar utveckling erkänts av många inom såväl akademien som planeringsbranschen, är planeringen av praktiska förutsättningar för konst och kultur - kulturell infrastruktur – bristfällig och ibland helt utebliven i Sverige idag. Syftet med studien är därför att utforska vilka förutsättningar som kan skapas för kulturell infrastruktur genom stads- och samhällsplanering i Sverige. Kulturell infrastruktur innefattar såväl hårda (såsom fysiska lokaler) som mjuka strukturer (såsom ekonomiskt stöd). Studien inriktar sig på offentliga verksamheter (främst kommunalt och regionalt) men behandlar även hur privata konsultfirmor kan skapa förutsättningar för kulturell infrastruktur.   Resultaten bygger på kvalitativa intervjuer med såväl konstnärer, konst- och kultursamarbetsorganisationer, arkitekter som tjänstepersoner på kommunal och regional nivå, samt på två enkätundersökningar med såväl konst- och kulturaktörer som planerare. Inom ramen för studien har även två exempelfall studerats – Fyrklövern i Upplands Väsby, samt Gatukonstfestivalen No Limit i Borås. Studien undersöker tre forskningsfrågor: 1) Vad för kulturell infrastruktur behövs i Sverige idag? 2) Vad hindrar etableringen av kulturell infrastruktur idag? 3) Vilken potential finns inom stads- och samhällsplanering att skapa förutsättningar för kulturell infrastruktur?   Studiens resultat visar att de former av kulturell infrastruktur som främst behövs i Sverige idag är Tillgängliga mötesplatser, Information och kunskap, samt Nätverk och Finansieringsformer. De tre största hindren som studien identifierar är Brist på värdering och ansvar för konst- och kultur, Finansiering och Struktur och organisation. Samverkan visar sig vara den viktigaste potentialen inom stads- och samhällsplanering, såväl över nivåerna kommun-region-stat, som med konst- och kulturaktörer, övriga civilsamhället och näringslivet. Två andra stora potentialer visar sig vara Strategisk planering och Krav och investering. Här ingår användningen av planeringsverktyg såsom Cultural planning och kulturkonsekvensanalyser. Studien visar på vikten att kommuner våga ställa högre krav och använda sin position som långsiktig samhällsutvecklare med planmonopol för att möjliggöra för konst och kultur - exempelvis genom att tillämpa ett poängsystem likt det i Fyrklövern vid markprissättning. Samtidigt understryks värdet av att inta en möjliggörande roll genom att stötta gräsrotsinitiativ och ge dem långsiktiga förutsättningar att driva kulturell infrastruktur. För att även göra kulturella infrastrukturer tillgängliga och inkluderande krävs ett kritiskt förhållningssätt som uppmärksammar dolda normer.   Resultaten av studien talar för komplexitetsteorins relevans för att förstå och beskriva kulturell utveckling. Teorin stöttar studiens resultat såsom vikten av att samarbeta över politikområden såsom bostäder och kollektivtrafik, samt vikten av att inte planera allt i detalj, utan att lämna rum för organisk vidareutveckling. Den förklarar också att det inte går att avkräva direkta och exakt mätbara effekter av konst- och kultursatsningar.     Studiens resultat har slutligen sammanfattats i form av rekommendationer för såväl stads- och samhällsplanerare som politiska och privata beslutsfattare. / Although the role of culture for sustainable development is recognized by many in the academy as well as in the urban and regional planning sector, the planning of practical conditions for arts and culture - cultural infrastructure - is inadequate and sometimes completely absent in Sweden today. The aim of this study is therefore to explore what conditions can be created for cultural infrastructure through urban and regional planning in Sweden. Cultural infrastructure includes both hard (such as physical premises) and soft structures (such as financial support). The study focuses on public activities (mainly municipal and regional) but also deals with how private consultancy firms can enable cultural infrastructure.   The results are based on qualitative interviews with artists, arts and culture associations, architects as well as municipal and regional planners. Moreover, the study comprises of two questionnaires aimed at art and culture actors and planners and architects from the municipal, regional and private sector. Within the study, two sample cases have been studied - Fyrklöven in Upplands Väsby, and the Street art festival No Limit in Borås. The study explores three research questions: 1) What kind of cultural infrastructure that is needed in Sweden today? 2) What prevents the development of Cultural Infrastructure? 3) What potential lies in urban and regional planning?   The results of the study show that the types of cultural infrastructure that are primarily needed in Sweden today are Available meeting places, Information and knowledge, as well as Networks and Funding. The three biggest obstacles identified is Lack of value and responsibility for art and culture, Funding and Structure and organization. Collaboration proves to be the most important potential in planning, both over the levels of municipal-region-state, as with art and culture actors and other civil society actors and businesses. Two other main potentials lie in Strategic planning, and Demands and investments. This includes application of planning tools such as Cultural Planning and Culture Impact Assessments. The study also highlights the importance that municipalities set higher demands and use their positions as long-term societal developers with monopoly in order to give room for art and culture – e.g. by applying a scoring system similar to that in Fyrklövern when pricing land. Moreover, the study points to the benefits and importance of supporting grassroots initiatives and providing them long-term conditions for driving cultural infrastructure. In order to make cultural infrastructures available and inclusive, a critical approach is also required that draws attention to hidden norms.   The results of the study speak for the relevance of the complexity theory in understanding and describing cultural development. This theory support results of the study such as the importance of collaborating over policy areas, e.g. housing and public transport, the importance of not planning everything in detail and instead leave room for organic development. It also explains that one cannot directly or precisely quantify the effects of art and culture efforts. The results of the study are finally summarized as recommendations for urban and regional planners as well as political and private decision-makers.

L’analyse de l’introduction du changement dans les systèmes de santé des pays en développement : le cas d’un système de surveillance épidémiologique en Haïti

Baldé, Thierno 02 1900 (has links)
Les systèmes de santé des pays en développement font face à de nombreux enjeux organisationnels pour améliorer l’état de santé de leur population. Au nombre de ces enjeux, il est fréquemment mentionné la présence d’organisations internationales ayant des objectifs et caractéristiques peu convergents et qui interviennent de façon non nécessairement coordonnée. Cette thèse explore la thématique de l’introduction du changement dans ces systèmes de santé en mettant un accent spécifique sur l’enjeu lié à la présence de ces organisations internationales. La méthodologie utilisée est une analyse de concept. Cette approche méthodologique consiste à effectuer des revues critiques de la littérature sur des concepts, à mobiliser de nouvelles approches théoriques pour clarifier ces concepts et à réaliser des études de cas pour leur mise à l’épreuve empirique. En nous appuyant sur la théorie de l’action sociale de Parsons, la théorie de la complexité ainsi que les expériences d’introduction du changement dans différents systèmes de santé, nous avons développé un cadre théorique d’analyse de l’introduction du changement dans les systèmes de santé des pays en développement (1er concept). Ce cadre théorique, qui suggère de concevoir le processus d’introduction du changement comme un système d’action sociale complexe et émergent, a été appliqué à l’analyse de l’introduction d’un système de surveillance épidémiologique en Haïti. Plus précisément, nous avons analysé une étape ainsi que certains aspects du mécanisme sous-jacent au processus d’introduction du changement. Ce faisant, nous avons analysé, dans les deux premiers articles de la thèse, l’étape d’adoption du système de surveillance épidémiologique (2ème concept) ainsi que les déterminants de la collaboration entre les organisations impliquées dans le processus d’introduction du changement (3ème concept). Les résultats de ces analyses nous ont permis d’objectiver de faibles niveaux d’adoption, ainsi qu’une faible articulation des déterminants de la collaboration entre les différentes organisations impliquées dans le processus d’introduction du changement. Partant de ces constats, nous avons pu mettre en évidence, dans le troisième article, une phase de « chaos » dans le fonctionnement du système de santé d’Haïti. Cette phase de « chaos », qui pourrait expliquer les difficultés liées à l’introduction du changement dans les systèmes de santé des pays en développement en général et plus particulièrement en Haïti, était caractérisée par la présence d’un ordre sous-jacent au désordre apparent dans le fonctionnement de certaines composantes du système de santé d’Haïti, l’existence d’une instabilité, d’une imprédictibilité ainsi que d’une invariance structurelle aux différents niveaux de gouvernance. Par ailleurs, cette recherche a également permis de démontrer que les caractéristiques du « chaos » sont entretenues par la présence de trois groupes de systèmes d’action sociale bien articulés et bien cohérents à tous les échelons de la pyramide sanitaire en Haïti. Il s’agissait des systèmes d’action liés aux agences de coopération bilatérale, ceux liés aux initiatives ou fondations internationales de lutte contre le sida et finalement ceux associés aux organisations onusiennes. Ces systèmes d’action sociale sont en outre associés à d’autres systèmes d’action plus complexes qui sont situés à l’extérieur du système de santé d’Haïti. Au regard de ces résultats, nous avons proposé une nouvelle approche permettant de mieux appréhender l’introduction du changement dans les systèmes de santé des pays en développement et qui s’inscrit dans une logique permettant de favoriser une plus grande variété et une plus grande diversification. Cette variété et cette diversification étant soutenue par la création et la mise en place de plusieurs interconnections entre tous les systèmes d’action en présence dans les systèmes de santé qu’ils soient d’appartenance nationale, internationale ou qu’ils agissent au niveau central, départemental ou local. La finalité de ce processus étant l’émergence de propriétés systémiques issues non seulement des propriétés des groupes de systèmes d’action individuels qui interviennent dans la constitution du système émergent, mais aussi d’autres propriétés résultant de leur mise en commun. / In an attempt to improve the health status of their population, health care systems in developing countries face several organizational issues. These issues include the presence of international organizations with different goals and characteristics, as well as little convergence and poor coordination. While focussing on this specific issue, the objective of this dissertation is to deeply explore the issues related to the process of introducing change in health care systems of developing countries. The research method for this study is a concept analysis that requires a literature review, the use of new theories to clarify these concepts as well as the use of case studies to empirically validate these concepts. Using Parsons’s social action theory and the complexity theory, a new theory of change (1st concept) was developed and applied to the process of introduction of an epidemiological surveillance system in Haiti. More specifically, in the first two articles, we have analysed the process of adopting the epidemiological surveillance system (2nd concept) and the determinants of collaboration among the different organizations involved in the change process (3rd concept). The results from these two articles enabled us to highlights the low level of adoption as well as the weak articulation of the determinants of collaborations between the various organizations involved in the change process. From these analyses, we were able to highlights the dynamics of chaos operating in Haiti’s health care system in the third article. This chaos stage which could enable us to show the difficulties associated with the introduction of change in health systems in developing countries in general, and Haiti in particular, was characterized by a hidden order underlying an apparent disorder in the operation of certain components of the Haitian’s health system, the existence of instability, unpredictability as well as structural invariance at various levels of governance. Moreover, this research also enabled us to show that these characteristics are maintained by the presence of three well articulated and coherent social action systems at all levels of the health pyramid. They are those related to bilateral cooperation agencies, those related to international foundations and global initiatives fighting against AIDS, and finally those associated with the United Nations Organizations. These social action systems are also associated with other more complex systems outside the Haiti’s health system. On the basis of these results, we proposed a new approach to understand the process of introducing change in health care systems of developing countries that would fit into the logic that supports the setting up a larger interconnections and diversification among various organizations involved.

On Invariant Formulae of First-Order Logic with Numerical Predicates

Harwath, Frederik 12 December 2018 (has links)
Diese Arbeit untersucht ordnungsinvariante Formeln der Logik erster Stufe (FO) und einiger ihrer Erweiterungen, sowie andere eng verwandte Konzepte der endlichen Modelltheorie. Viele Resultate der endlichen Modelltheorie nehmen an, dass Strukturen mit einer Einbettung ihres Universums in ein Anfangsstück der natürlichen Zahlen ausgestattet sind. Dies erlaubt es, beliebige Relationen (z.B. die lineare Ordnung) und Operationen (z.B. Addition, Multiplikation) von den natürlichen Zahlen auf solche Strukturen zu übertragen. Die resultierenden Relationen auf den endlichen Strukturen werden als numerische Prädikate bezeichnet. Werden numerische Prädikate in Formeln verwendet, beschränkt man sich dabei häufig auf solche Formeln, deren Wahrheitswert auf endlichen Strukturen invariant unter Änderungen der Einbettung der Strukturen ist. Wenn das einzige verwendete numerische Prädikat eine lineare Ordnung ist, spricht man beispielsweise von ordnungsinvarianten Formeln. Die Resultate dieser Arbeit können in drei Teile unterteilt werden. Der erste Teil betrachtet die Lokalitätseigenschaften von FO-Formeln mit Modulo-Zählquantoren, die beliebige numerische Prädikate invariant nutzen. Der zweite Teil betrachtet FO-Sätze, die eine lineare Ordnung samt der zugehörigen Addition auf invariante Weise nutzen, auf endlichen Bäumen. Es wird gezeigt, dass diese dieselben regulären Baumsprachen definieren, wie FO-Sätze ohne numerische Prädikate mit bestimmten Kardinalitätsprädikaten. Für den Beweis wird eine algebraische Charakterisierung der in dieser Logik definierbaren Baumsprachen durch Operationen auf Bäumen entwickelt. Der dritte Teil der Arbeit beschäftigt sich mit der Ausdrucksstärke und der Prägnanz von FO und Erweiterungen von FO auf Klassen von Strukturen beschränkter Baumtiefe. / This thesis studies the concept of order-invariance of formulae of first-order logic (FO) and some of its extensions as well as other closely related concepts from finite model theory. Many results in finite model theory assume that structures are equipped with an embedding of their universe into an initial segment of the natural numbers. This allows to transfer arbitrary relations (e.g. linear order) and operations (e.g. addition, multiplication) on the natural numbers to structures. The arising relations on the structures are called numerical predicates. If formulae use these numerical predicates, it is often desirable to consider only such formulae whose truth value in finite structures is invariant under changes to the embeddings of the structures. If the numerical predicates include only a linear order, such formulae are called order-invariant. We study the effect of the invariant use of different kinds of numerical predicates on the expressive power of FO and extensions thereof. The results of this thesis can be divided into three parts. The first part considers the locality and non-locality properties of formulae of FO with modulo-counting quantifiers which may use arbitrary numerical predicates in an invariant way. The second part considers sentences of FO which may use a linear order and the corresponding addition in an invariant way and obtains a characterisation of the regular finite tree languages which can be defined by such sentences: these are the same tree languages which are definable by FO-sentences without numerical predicates with certain cardinality predicates. For the proof, we obtain a characterisation of the tree languages definable in this logic in terms of algebraic operations on trees. The third part compares the expressive power and the succinctness of different ex- tensions of FO on structures of bounded tree-depth.
