Mapeamento da exclusão social em cidades médias : interfaces da geografia econômica com a geografia política /

Vieira, Alexandre Bergamin. January 2009 (has links)
Orientador: Raul Borges Guimarães / Banca: Arthur Magon Whitacker / Banca: Everaldo Santos Melazzo / Banca: Júlio César de Lima Ramires / Banca: Vitor Ribeiro Filho / Resumo: Nesta tese partimos da hipótese de que nas cidades médias brasileiras ocorrem processos sociais excludentes perversos. O "lugar de cada um" ou a separação espacial das diferentes classes sociais nas cidades médias nos remete à discussão da banalização das desigualdades e a produção e reprodução do espaço banal. O mapeamento da exclusão social permite-nos compreender essa banalização por meio das interfaces entre o econômico e o político, pois não entendemos as cidades médias sem analisar a sua inserção na rede de cidades (geografia econômica) como não podemos compreender a exclusão social sem investigar as especificidades da produção e reprodução do espaço banal (geografia política). Uberlândia, São José do Rio Preto e Presidente Prudente foram escolhidas como recorte empírico que permitiu-nos identificar os processos que envolvem os impactos negativos das desigualdades sociais. É também o elemento que possibilita reconhecer as matrizes excludentes e como estas são reproduzidas. Partimos, assim, do princípio de que a análise e caracterização do conceito de exclusão social, bem como o mapeamento dos indicadores de exclusão constituem-se em uma chave para compreender a banalização das desigualdades sociais e espaciais nessas três cidades médias. / Abstract: In this research, we discuss the social exclusion processes in the intermediate Brazilian cities. Using an empirical study across Uberlandia, Sao Jose do Rio Preto and Presidente Prudente, it was possible to identify the negative impacts and social inequalities that involve the Brazilian urban production. It is also the element that makes possible both recognise the excluding patterns and find out how they are produced. Then we assume that the analysis and characterisation of the concept of social exclusion as well as the mapping of exclusion indicators constitute the key point for understanding the vulgarisation of social and spatial inequalities in these three intermediate cities. / Doutor

Pedagogiska utmaningar i förskolan : En kvalitativ intervjuundersökning om förskolepedagogers förhållningssätt till social inkludering / Educational challenges in preschool : A qualitative interview survey on preschool educators relate to social inclusion

Sakao, Yuko, Hägglund Hossain, Isabelle January 2018 (has links)
The aim of the study is to contribute to a better understanding of how educators relate to social inclusion in preschool. Educators' perception of social inclusion is an important topic to investigate because there are often children who temporarily or permanently need special support in preschool. The inclusion of children in preschool is considered important and educators have a central role and responsibility to include all children in preschool. According to our experience, there is a great variety of how educators perceive the work of social inclusion in preschool.   In order to answer the question of how educators relate to social inclusion in preschool, it is chosen to conduct semi-structured, qualitative interviews. We interviewed eight preschool educators to find out how they perceive their work with social inclusion. The two themes that appeared in the educators’ answers were inclusion and exclusion.   The study found that preschool educators' work with social inclusion is complex. Educators in the study considered that all children have the right to enter into a social context, to be socially included, and they acknowledges their responsibility to ensure that all children are included. They expressed that it is not the responsibility of the children, but the adults, to ensure that all children are included in the group. Several of the educators express that there are difficulties and challenges with inclusion work, and state that children need to master certain social skills in order to be able to be included. Adaptation will lead to all children being given the opportunity to participate and succeed. The study further shows that the interviewed educators consider themselves responsible for creating opportunities that enable inclusion. The result of the study shows that for a functioning work with social inclusion, educator’ needs to form a common view and gain an understanding of the concepts of inclusion and exclusion among preschool teachers. The way educators perceive social inclusion, affects how educators work with social inclusion in preschool. In order to gain insight into, and in a more concrete way, an understanding of how preschool educators relate to social inclusion, it was chosen to accomplish this study. It is hoped that other preschool educators can benefit from the study's results in their professional role in the future.

Practising talent management : processes of judgment, inclusion and exclusion

Avigdor, Tali January 2017 (has links)
Talent management is an organisational process aimed at maximising the benefit gained from the organisation's workforce, mostly by assessing the future potential of senior organisational members to fill key positions based on their proportional contribution to the business. Despite the increasing prevalence of talent management, evidence is accumulating to indicate an extremely low success rate of just 20-25% in predicting high performers. While talent management continues to address a growing business need, a better understanding of the process may help to refine its practice. The underpinning assumptions of the practice of talent management are that organisations are systemic and linear, and that talent management must produce a single answer identifying what it means to be a 'talent' in any specific circumstance. As a profession, talent management also maintains a fantasy of control: the expectation that assessed individuals will indeed behave as anticipated, and that stated targets will remain unchanged. As a progressive and trending HR process, talent management's close connection to organisational power relations and political dynamics is rarely acknowledged. The emotional toll on assessed senior executives, as well as potential ramifications for their colleagues, is also often overlooked, despite the significant implications for individual careers and broader inferences of inclusion-exclusion inherent in the process of talent selection. Talent management practitioners and scholars tend not to consider the impact on individuals of inaccurate assessments and mistaken decisions. As a talent manager practitioner who decrees the fate of individuals, such glaring oversights provoked in me an acute ethical anxiety that drove this research. This work offers a critical perspective on the practice of talent management - in particular, the process of judgment involved in the assessment of 'high potentials' and the potent dynamics of inclusion in/exclusion from the talent group. Having witnessed first-hand the inconsistency between apparently robust predictions (based on best practice) and subsequent outcomes, I began this research with strong feelings of ambivalence towards my practice of 25 years and my prospering business of 10 years. The critical perspective of the current study took shape within the research framework, which is based on the philosophy of pragmatism and the complex responsive process of relating that draws on it, as well as on process sociology and complexity sciences. The research methodology insists that scholars take their own direct experience seriously, collect their raw data through writing narratives, and then exercise reflection and reflexivity both as individuals and as part of the Doctor of Management (DMan) learning community. The narratives 'translate experience so that it is meaningful to the reader' (Cunliffe, 2010, p. 228). Applying this innovative approach not only to my research, but also to my professional practice, has led me to challenge the most fundamental assumptions of talent management. I now have a deeper and more nuanced understanding of the process of judgment at its core, and have developed a new way to approach and implement this process within my work. This thesis culminates in three main arguments describing talent management from a new perspective, as well as redefining the role and degree of involvement of talent management consultants. First, the central process of judgment emerged not as an objective analysis communicated in a unidirectional, linear way from the assessor to the assessed, but rather as a relational and social process that involves shifting power relations and an inclusion-exclusion dynamic influenced by many unpredictable factors. Second, from the perspective of the research framework, the assessor can no longer be seen as an objective observer, but must be regarded as a participant who is simultaneously both involved and detached and who must rely on their practical judgment. Talent management's traditional promise of future-oriented focus and reliable predictions is illusory, given that all participants are continuously merging their ongoing experiences to spontaneously co-create the future in unpredictable ways. . Understanding that the assessment process is not a simple numerical exercise (ranking individuals on various scales) and that no single truth can be obtained through an assessment process (since assessment results are co-created with all participants in the process) has eased my ethical concerns and enabled me to continue practising my profession with confidence, by taking a fresh viewpoint of what it is that I am doing. It is my hope that other talent management practitioners will find these insights useful and generalisable, and valid to their own practice - extrapolating from the local to the global.

Factors influencing e-inclusion in the UK : a study based on uses and gratifications theory and decomposed theory of planned behaviour

Almuwil, Ahlam A. January 2014 (has links)
The parallel between e-government and e-Inclusion research are critically important. It helps to understand how policies, society, organizations, and information technologies come together and it also helps to understand how the e-Inclusion factors impact e-government use and vice versa. This study attempts to explore the theoretical and practical intersections of e-Inclusion and e-adoption (Particularly e-government) and to show how they complement and possibly enrich the potential of e-Inclusion research. The rationale for this approach is that combining research on e-Inclusion and e-government has the potential to better understand the factors influencing e-Inclusion since they both share a common theme of Inclusive e-government. The aim of this research is to examine the factors that influence e-Inclusion in the context of e-government in the UK, through combining the decomposed theory of planned behaviour with Use and Gratification Theory (U&G). These two theories are used to develop a conceptual model for studying the multi-facetted dimensions of e-Inclusion. The two theories are chosen because of their appropriateness for e-Inclusion research; the critical factors that influence e-inclusion can be covered by (DTPB) constructs while the individual’s gratifications that determine using specific Internet activities is covered by (U&G) To fulfil the research aim and objectives, a quantitative research method was employed. The research subjects were citizens who are Internet users. Their views were sought through a survey that included 510 self-administered and group-administrated questionnaires. The conceptualisations of e-Inclusion and e-government have important implications for both researchers and policymakers. For researchers, this study delineates the complex and recursive relationships between e-Inclusion and e-government contributing towards the exiting limited body of knowledge in the field. For practice, it offers directions to help create a more comprehensive strategy that takes into consideration the alignment of e-government initiatives and e-inclusion policies.

Characterization of Carbonaceous Aerosol over the North Atlantic Ocean

January 2011 (has links)
abstract: Atmospheric particulate matter has a substantial impact on global climate due to its ability to absorb/scatter solar radiation and act as cloud condensation nuclei (CCN). Yet, little is known about marine aerosol, in particular, the carbonaceous fraction. In the present work, particulate matter was collected, using High Volume (HiVol) samplers, onto quartz fiber substrates during a series of research cruises on the Atlantic Ocean. Samples were collected on board the R/V Endeavor on West&ndash;East (March&ndash;April, 2006) and East&ndash;West (June&ndash;July, 2006) transects in the North Atlantic, as well as on the R/V Polarstern during a North&ndash;South (October&ndash;November, 2005) transect along the western coast of Europe and Africa. The aerosol total carbon (TC) concentrations for the West&ndash;East (Narragansett, RI, USA to Nice, France) and East&ndash;West (Heraklion, Crete, Greece to Narragansett, RI, USA) transects were generally low over the open ocean (0.36&plusmn;0.14 &mu;g C/m3) and increased as the ship approached coastal areas (2.18&plusmn;1.37 &mu;g C/m3), due to increased terrestrial/anthropogenic aerosol inputs. The TC for the North&ndash;South transect samples decreased in the southern hemisphere with the exception of samples collected near the 15th parallel where calculations indicate the air mass back trajectories originated from the continent. Seasonal variation in organic carbon (OC) was seen in the northern hemisphere open ocean samples with average values of 0.45 &mu;g/m3 and 0.26 &mu;g/m3 for spring and summer, respectively. These low summer time values are consistent with SeaWiFS satellite images that show decreasing chlorophyll a concentration (a proxy for phytoplankton biomass) in the summer. There is also a statistically significant (p<0.05) decline in surface water fluorescence in the summer. Moreover, examination of water&ndash;soluble organic carbon (WSOC) shows that the summer aerosol samples appear to have a higher fraction of the lower molecular weight material, indicating that the samples may be more oxidized (aged). The seasonal variation in aerosol content seen during the two 2006 cruises is evidence that a primary biological marine source is a significant contributor to the carbonaceous particulate in the marine atmosphere and is consistent with previous studies of clean marine air masses. / Dissertation/Thesis / M.S.

Developmental Pathways to Antisocial Behavior in Early-Adolescence: Examining Changes in Aggression and Peer Exclusion through Childhood

January 2011 (has links)
abstract: This study examined the influence of childhood aggression, peer exclusion and associating with deviant peers on the development of antisocial behavior in early adolescence. To gain a stronger understanding of how these factors are associated with antisocial behavior and delinquency, multiple alternative pathways were examined based on additive, mediation and incidental models. A parallel process growth model was specified to assess whether early childhood aggression and peer exclusion (in 1st grade) and intra-individual increases in aggressive behaviors and exclusion through childhood (grades 1 to 6) are predictive of associating with deviant peers (in 7th grade) and antisocial behavior (in 8th grade). Based on a sample of 383 children (193 girls and 190 boys), results showed the strongest support for an additive effects model in which early childhood aggression, increases in aggression, increases in peer exclusion and associating with more deviant peers all predicted antisocial behavior. These findings have implications for how children's psychological adjustment is impacted by their behavioral propensities and peer relational context and the importance of examining developmental processes within and between children over time. / Dissertation/Thesis / M.S.

Analysis of Photocatalysis for Precursor Removal and Formation Inhibition of Disinfection Byproducts

January 2011 (has links)
abstract: Disinfection byproducts are the result of reactions between natural organic matter (NOM) and a disinfectant. The formation and speciation of DBP formation is largely dependent on the disinfectant used and the natural organic matter (NOM) concentration and composition. This study examined the use of photocatalysis with titanium dioxide for the oxidation and removal of DBP precursors (NOM) and the inhibition of DBP formation. Water sources were collected from various points in the treatment process, treated with photocatalysis, and chlorinated to analyze the implications on total trihalomethane (TTHM) and the five haloacetic acids (HAA5) formations. The three sub-objectives for this study included: the comparison of enhanced and standard coagulation to photocatalysis for the removal of DBP precursors; the analysis of photocatalysis and characterization of organic matter using size exclusion chromatography and fluorescence spectroscopy and excitation-emission matrices; and the analysis of photocatalysis before GAC filtration. There were consistencies in the trends for each objective including reduced DBP precursors, measured as dissolved organic carbon DOC concentration and UV absorbance at 254 nm. Both of these parameters decreased with increased photocatalytic treatment and could be due in part to the adsorption to as well as the oxidation of NOM on the TiO2 surface. This resulted in lower THM and HAA concentrations at Medium and High photocatalytic treatment levels. However, at No UV exposure and Low photocatalytic treatment levels where oxidation reactions were inherently incomplete, there was an increase in THM and HAA formation potential, in most cases being significantly greater than those found in the raw water or Control samples. The size exclusion chromatography (SEC) results suggest that photocatalysis preferentially degrades the higher molecular mass fraction of NOM releasing lower molecular mass (LMM) compounds that have not been completely oxidized. The molecular weight distributions could explain the THM and HAA formation potentials that decreased at the No UV exposure samples but increased at Low photocatalytic treatment levels. The use of photocatalysis before GAC adsorption appears to increase bed life of the contactors; however, higher photocatalytic treatment levels have been shown to completely mineralize NOM and would therefore not require additional GAC adsorption after photocatalysis. / Dissertation/Thesis / M.S.

La crise argentine de 2001 et ses conséquences : un regard à travers la littérature et le cinéma argentin des années 2000 / The Argentine crisis of 2001 and its consequences, as seen through Argentine literature and cinema of the 2000s

Ponze, Adrian 06 March 2017 (has links)
Ce travail est le résultat d'une recherche pluridisciplinaire basée sur l'hypothèse suivante : il existe une certaine porosité entre récits fictionnels et productions scientifiques en sciences sociales. A partir d‘un cadre théorique et méthodologique qui comprend la sociologie de la culture et la théorie littéraire et cinématographique, nous avons fait l‘analyse critique d'un corpus de textes de fiction relevant de la NNA (Nouvelle Narration Argentine) et de films relevant du NCA (Nouveau Cinéma Argentin), c‘est-à-dire des deux principaux courants artistiques auxquels une nouvelle génération d'auteurs, émergée en Argentine au début du XXIe siècle, a donné forme.Le corpus, d‘une quinzaine de romans et d‘autant de films, a été constitué selon un critère qui caractérise les œuvres choisies : la description de la crise en général et la présence spécifique d‘exclus économiques, en particulier les migrants (le départ d‘Argentins et l‘arrivée d‘étrangers), les villas miseria et leurs habitants, ainsi que la présence de membres de la diversité sexuelle.Nos recherches se sont orientées, d‘une part, vers les transformations observées dans les champs littéraire et cinématographique, notamment vers les changements touchant aux modes de production et de distribution des œuvres, et, d‘autre part, vers la manière dont sont représentés, dans les médias et les œuvres artistiques, les secteurs de la société traditionnellement exclus.L'observation de ces changements et modes de représentation à travers des récits fictionnels permet de confirmer l‘hypothèse de départ, dans la mesure où certains romans et films ont une valeur documentaire pour la recherche en sciences sociales, notamment dans des disciplines telles que l'histoire ou la sociologie. / This work is the result of multidisciplinary research in which, using the theoretical and methodological framework of literary and film theory, and the sociology of culture, we have demonstrated that the boundaries between fiction and social science writing are porous. A corpus of fifteen fictional texts identified with the New Argentina Narrative (NAN) movement, and fifteen films made by the New Argentine Cinema (NAC) was analysed. New Argentina Narrative and NAC represent the production of a new generation of Argentine writers and filmmakers between 2000 and 2010. These works included the following topics: migrations from Argentina and immigration, poverty (the villas miseria inhabitants), and gender and sexual diversity in Argentina. The objectives of this study are to evaluate the transformations of Argentine society and how these were represented by a new generation of Argentine writers and filmmakers. Additionally, we have studied the influence of the socio-economic context on artistic expression. Thus, we have analysed not only the aesthetic dimension, but also the modes of production and distribution of Argentina literature and cinema, encompassing the processes of creation, editing and distribution. The observation of these processes through novels and films has allowed us to conclude that some literary and film fiction may have a documentary or testimonial value for research in social science disciplines such as history and sociology.

Får alla vara med? : En studie om hur förskollärare förstår barns inkludering och exkludering. / Can everyone join? : A study on how preschool teachers understand children's inclusion and exclusion.

Isoluoma, Rebecca, Östgren, Erika January 2018 (has links)
Syftet med denna studie är att få kunskap om hur förskollärare agerar och stödjer barn i deras tillträde i den fria leken samt undersöka vilka tillträdesstrategier som används av barnen utifrån ett förskollärarperspektiv. Studien är kvalitativ och använder semistrukturerade intervjuer med sju förskollärare som metod. Data transkriberades och analyserades genom att använda Corsaros studier med begreppen tillträdesstrategier samt kamratkulturer. Vid analysen framkom två teman: stöttning och tillgänglighet samt ”får jag vara med?”. Båda teman har flera underrubriker. Studien visar att det fanns två olika uppfattningar kring stöttning och tillgänglighet, där den aktiva förskolläraren uppfattas som att förebygga exkludering långsiktigt medan den avvaktande förskolläraren har en mer kortsiktig plan och löser problemen som finns här och nu. Studien visar även förskollärarnas upplevelser kring barnens hinder och vägar till lek och vilka tillträdesstrategier som förskollärarna anser fungerar mer eller mindre bra för att få tillträde till den fria leken. En slutsats som framkom i vår studie utifrån tillträdesstrategier ur ett förskollärarperspektiv är att det inte är den strategi som förskollärarna uppfattar förekommer mest som är den som oftast leder till lek, något som även Corsaro har kommit fram till i sina studier. / <p>Fastställt via akademichefsbeslut HIG-STYR 2019/7 den 2019-01-07</p><p>Daniel Petterson, fil dr, univ. lekt Pedagogik och Erika Björklund, fil dr, univ. lekt Pedagogik går in som examinatorer på PEG700 under veckorna 1 till och med 3, 2019 då Peter Gill, prof.
