Little attention has been paid in Canadian Child Welfare research to the role that training plays in engaging new workers as they enter the complex role of child protection. Focusing on learning principles such as child neglect and working with an ethno-racial Other, it was important to understand what workers took away from their engagement in training and how this was implemented in practice. A mixed methods approach using critical analysis of the OACAS Handouts was used to inform the Semi Structured Interviews conducted with frontline C.A.S. workers. Critical Race Analysis provides theoretical foundation to understand how the ethno-racial other is perceived and enacted in discourse that workers take away into practice. Findings suggest that C.A.S. workers have a conflicted view of training due to the nature and context in which they practice. Aside from the benefits of training, workers have a lot to say about how it could be structured in order to benefit practice. Workers also have complex and conflicting views on neglect, some of which are learned through training and then exacerbated through practice. Workers practice principles on engaging with an ethno-racial other was not influenced through training, but through their own learning processes as influenced by practice and earlier education. These factors relating to child welfare workers can help influence future training within C.A.S. organizations across Canada. / Thesis / Master of Social Work (MSW)

O projeto de espaços de trabalho exige, por parte do projetista, equacionar conflitos entre as diversas lógicas parciais dos vários usuários de um mesmo artefato. Compreender as relações estabelecidas entre os vários subsistemas que compõem a atividade de trabalho e dos ambientes leva, inevitavelmente, à necessidade de se desenvolver métodos de projeto que possam contemplar demandas inerentes a essa complexidade. Com efeito, poderíamos inferir que, na verdade, o que é preciso considerar na hora do projeto é a existência de uma interface entre o artefato de trabalho e o usuário. É o exercício pleno do uso dessa interface que permite aos usuários construírem sua experiência. Nessa experiência, encontramos os requisitos de projeto, e, para recuperá-la e fazer emergirem as necessidades do projeto, devemos lançar mão de métodos que se adéquem às condições atuais da prática projetual e às situações reais de uso dos artefatos. A evolução do artefato para instrumento resulta da associação dos artefatos com os esquemas de utilização dos seus usuários, reflexo da sua experiência. Metodologias como a Análise Ergonômica do Trabalho e a Avaliação Pós-Ocupação, apoiadas na Teoria da atividade, e por ela guiadas, podem ajudar na construção de uma reflexão consciente sobre a complexidade e as variáveis que surgem no uso dos ambientes de trabalho. O nosso grande labor no estudo de caso fundamenta-se no acompanhamento da atividade em curso, numa sala de controle de um sistema de Metrô. Durante as observações e levantamentos realizados, pudemos identificar a distância entre o projeto da sala e o trabalho real dos operadores e seus esquemas de utilização. O projeto tem sido reflexo de um processo de concepção que precisa ser incrementado, incorporando, definitivamente, características da atividade e a experiência dos usuários. / Design of work spaces demands from the designer solving conflicts which arise from the many partial logics of the various users of a same artifact. To understand the relations established between the many subsystems which make up the activity of work and its environment, leads inevitably to the need of developing design methods capable of dealing with the inherent demands of this complexity. Under this light, it is possible to infer that the existence of an interface between the work artifact and the user has to be considered when drafting a project. It is the very exercise of the use of this interface which allows users to construct their own experiences. Consequently, the design requirements are found within the experience itself, and, to recover it and impel the emergence of design\'s needs, one must forgo the methods which are linked to the current conditions of the accepted practices of design. The evolution from artifact to instrument results from the association of artifacts with the utilization schemes presented by users, a reflection of their own experiences. Methodologies, such as Ergonometric Analysis of Work and Post-Occupancy Evaluation, supported and guided by the Theory of activity, can help the construction of a conscientious reflection on both, complexity and variables which arise throughout the use of a work environment. The major work realized in this case study is based on the follow-up of in-progress activities within a subway\'s system control room. Observation and surveys carried out along this study identified a void between the design of the control room and the real work performed by the employees and their utilization schemes. Design should reflect a conception process which incorporates characteristics of both user activities and user experience.

O trabalho dos usuários em sistemas de informação é uma atividade social que envolve grupos de pessoas que cooperam entre si para desempenhar as mais variadas funções. A natureza da cooperação, por si só é complexa e depende dos indivíduos envolvidos, do ambiente físico e da organização onde o trabalho se desenvolve. Os aspectos ligados ao trabalho cooperativo dos usuários não são considerados no enfoque tradicional da engenharia de software, uma vez que o usuário é visto de modo independente do meio ou grupo em que está inserido, com o modelo individual generalizado para o estudo do comportamento coletivo envolvendo todos os usuários. O objetivo deste trabalho é propor um processo de requisitos de software para tratar as questões envolvendo o trabalho cooperativo em sistemas de informação que apresentem coordenação distribuída nas ações dos usuários e a comunicação entre eles ocorre, preponderantemente, de modo indireto por meio dos dados inseridos no uso do software. Para tanto, a pesquisa faz uso de conceitos da ergonomia, da cognição e da engenharia de software. Utiliza-se a pesquisa-ação como metodologia de pesquisa em três ciclos, aplicada durante o desenvolvimento de um sistema de workflow corporativo em uma empresa de pesquisa tecnológica. No primeiro ciclo, o processo trata da definição dos requisitos do domínio do problema e das contribuições individuais dos usuários. No segundo ciclo, as contribuições do grupo (suas ações e inter-relações) são consideradas com as contribuições individuais pela simulação da solução proposta. No terceiro ciclo, o processo trata do refinamento dos requisitos do trabalho cooperativo, com o software em uso real no ambiente de trabalho. Os resultados obtidos no final do ciclo 2 e início do ciclo 3 durante a aplicação do processo em campo, mostraram a necessidade de melhoria do processo. Esta evolução é necessária, visto que a inclusão do sistema informatizado altera o ambiente de trabalho dos usuários, passando da interação face a face para a interação mediada pelo software. Os resultados obtidos evidenciaram que o maior grau de consciência dos usuários sobre como os inter-relacionamentos de suas atividades são realizados contribuem para um decréscimo em seus erros individuais, diminuindo o retrabalho de recodificação do software e acima de tudo o uso inadequado do sistema, evitando a propagação das consequências desses erros nos resultados finais do trabalho em grupo. / Users\' work in information systems is a social activity that involves people groups cooperating to perform many different functions. The nature of cooperation itself is complex and depends on the people involved, on the workplace environment and on the organization in which the work develops. Aspects related to the users\' cooperative work are not considered in the traditional approach of software engineering, since the user is viewed independently of his/her workplace environment or group, with the individual model generalized to the study of collective behavior of all users. This work proposes a process for software requirements to address issues involving cooperative work in information systems that provide distributed coordination in the users\' actions and the communication among them occurs indirectly through the data entered while using the software. To achieve this goal, this research uses ergonomics, cognition and software engineering concepts. Research-action is used as a research methodology applied in three cycles during the development of a corporate workflow system in a technological research company. In the first cycle, the proposed process exposes the definition of the problem domain requirements and the users\' individual contributions.

The results at the end of cycle 2 and the beginning of cycle 3 during the process application in the field show the need for process improvement. This is necessary because the inclusion of a computer system changes the users workplace, from the face to face interaction to the interaction mediated by the software. The results show that the highest degree of users\' awareness as the interrelationship of their activities are carried out contributes to a decrease in their individual errors, reducing software recoding rework and above all the inappropriate use of the system, avoiding the spread of the consequences of these errors in the final results of the group work.

Il tema centrale del presente lavoro di tesi è l’affidamento etero-familiare di bambini e ragazzi, temporaneamente privi di un adeguato contesto familiare in cui vivere e, per questa ragione, affidati alle cure di un’altra famiglia, per un periodo di tempo determinato. L’affido familiare si considera un istituto giuridico complesso in quanto si fonda su un delicato intreccio di relazioni tra famiglia d’origine, bambino, famiglia affidataria, operatori dei servizi e autorità giudiziaria. La finalità che ha guidato il lavoro di ricerca quantitativa è l’analisi dei progetti di affido etero-familiare, disposti dal Tribunale per i Minorenni di Milano, mettendo a fuoco i passaggi chiave per il loro avvio e realizzazione e gli snodi critici che si incontrano lungo il percorso. La ricostruzione dei processi di affido familiare è stata realizzata a partire dalle indicazioni del “buon affido”, emersi da due importanti lavori di revisione della letteratura internazionale (Wilson et al., 2004; Raineri e Calcaterra, 2017). L’approccio di studio utilizzato è l’analisi documentaria e la fonte di informazioni scelta i fascicoli dei bambini e ragazzi per cui il Tribunale ha emesso tra il 2010 e il 2014 un decreto di collocamento in famiglia affidataria. Per analizzare i progetti di affido etero-familiari, è stata costruita una “scheda di rilevazione” mediante cui si sono “interrogati” i fascicoli, ottenendo dei dati che è stato possibile poi elaborare statisticamente, mediante analisi del contenuto di tipo quantitativo. La tesi si struttura in due parti: la prima pone le fondamenta teoriche del progetto di ricerca, offrendo una panoramica delle fonti giuridiche in materia di minori e famiglia e del sistema di protezione e tutela dei bambini e ragazzi, con particolare attenzione all’istituto dell’affido familiare e alle tappe operative per la sua promozione e realizzazione, mentre la seconda è dedicata all’illustrazione del disegno della ricerca e all’analisi dei dati raccolti mediante il lavoro di “intervista” a più di cinquecento fascicoli. / Foster care is a complex intervention in child protection and for social workers and Juvenile Courts it’s difficult to identify exactly the outcomes of this care experience. Although his thirty-year history, in the Italian context, foster care represents a challenge, not only for social workers, but also for the Court that decide it, for children and their families and for foster families. This thesis is about foster care projects decided by the Juvenile Court of Milan, in Italy. The research is firstly based on an international literature review of researches on foster care with the aim to identify factors for a “good foster care project” and to create a scheme of success indicators. Starting from the indications emerged from the literature review, the aim of the research was to realize a description of foster care projects decided by the Juvenile Court of Milan from 2010 to 2014. The data collected are analyzed considering the factors for a good foster care placement identified through the literature review. Following a quantitative method, the main part of the research focused on Juvenile Court’s case files analysis. The information about foster care project contained in the documents are collected by a questionnaire. The sample consisted of 308 children for whom the Juvenile Court decided foster care placement. The documentary analysis aimed to recognize and to describe the foster care projects, considering key aspects arisen from the literature review, such as the matching and planning the foster placement, the work with birth families, foster families and foster children, the contacts between the child and his family, the relationship between the two families, the support to foster placement, the project’s conclusion and the possible reunification. This study offers an overview on social work practice in foster care placement in Lombardy, a region of Italy, highlighting also the partnership among different welfare services and the Juvenile Court. The results encourage a reflection on aspects considered important in foster care by social workers in the child protection and the other protagonists of this important care experience.

Cette thèse d’ergonomie s'inscrit dans le champ de l'organisation. Les nouvelles formes d'organisation et l'accroissement des activités de service soulèvent de nouveaux enjeux qui invitent l'ergonomie à se préoccuper de l'objet « organisation » et à échanger avec les sciences de gestion. Progressivement, une vision instrumentale de cet objet est proposée permettant de rompre avec les approches classiques et de penser l’articulation entre la structure organisationnelle et les mécanismes d’appropriation. L'ergonomie apparaît alors légitime à intervenir sur cet objet : ses objectifs et sa contribution historique aux savoirs de conception facilitent sa participation aux transformations de l'organisation. La thèse défendue est que l'organisation doit être conçue ou reconçue sous l'angle du développement. Le développement dont il est question ici est emprunté aux travaux à focalisation économique et renvoie plus spécifiquement à l'approche par les capabilités. Cette approche s'intéresse à ce que chaque individu est réellement en mesure de faire. Ceci suppose un environnement favorable, dit « capacitant », qui doit guider l'action de l'ergonome. En poursuivant cet objectif, l'ergonome développe des méthodologies d'intervention qui peuvent également porter les prémices d'une organisation « capacitante » propice aux débats, à la construction de l'activité et au travail d'organisation.Dans cette optique, une recherche a été conduite à l’occasion de la mise en place d’un Centre de Services Partagés au sein d'un grand groupe. Une méthodologie de recherche et d'expérimentation a été définie en fonction des possibilités du contexte. Elle comporte trois étapes.La première étape analyse l'existant, identifie les questions non résolues par l'organisation et caractérise les déterminants des contradictions auxquelles l'activité doit faire face. Elle met en évidence que la structure organisationnelle, pensée par d'autres, a été imposée aux acteurs. De manière générale, les opportunités de choix, le rayon d'action et les possibilités effectives de réaliser un travail de qualité diminuent par rapport à la situation avant le changement. La seconde étape s'intéresse à la manière dont les opérateurs tentent de reconcevoir l'organisation dans l'usage. La façon dont ces tentatives sont discutées, leurs coûts et leurs effets sur la structure organisationnelle sont ensuite analysés. Il ressort que les opérateurs tentent de transformer les ressources en capabilités c'est-à-dire en possibilités effectives de faire un travail de la meilleure qualité possible. Pour cela, l'organisation du travail est modifiée, les procédures remises en question et contournées : le « client » est progressivement transformé en partenaire de l'activité mais dans un contexte contraint et figé. La troisième étape vise, à partir des pratiques et des souhaits des acteurs, à tester in situ une méthodologie de changement, la co-analyse constructive des pratiques. Cette méthodologie cherche à expérimenter une organisation capacitante et a pour objectif d’établir un environnement capacitant, favorable au déploiement de l'activité et à la réussite des acteurs. Des visites sont organisées afin d’inviter chaque opérateur à observer l'activité de son partenaire. L'activité « ici et maintenant » constitue alors un objet de dialogues, facilitant une pratique réflexive sur l'activité collective conjointe et une transformation des règles et pratiques. Ainsi, la recherche-expérimentation menée conduit à de nouvelles solutions organisationnelles et à la mise en mouvement de l'organisation. Le développement apparaît dès lors comme un objectif et un moyen de l'action menée. L'analyse diagnostique permet d'identifier ce qui autorise et entrave ce développement. L'action ergonomique est ensuite construite de façon à favoriser ce développement au cours même de l’action et a posteriori. / This thesis in ergonomics takes its place in organization studies. New forms of organization, along with the increasing importance of service activities, raise new issues that invite ergonomics to focus on the object of “the organization” and exchange knowledge with management science. An instrumental vision of this object is gradually emerging, making it possible to break away from classical approaches and to focus on the articulation between the organizational structure and mechanisms of appropriation. Ergonomics then emerges as a legitimate contributor to intervene on this object. Its goals and historical contribution to design knowledge both facilitate its participation to transforming organizations. The thesis defended here is that organizations should be designed or redesigned from the point of view of development. The view of development used here is borrowed from work with an economic focus, and relates more specifically to a capability-based approach. This approach focuses on what each individual is truly able to do. This implies a favorable, “enabling” environment that must guide the action of ergonomists. By pursuing this goal, ergonomists develop strategies of intervention that can also bear the premises of an enabling organization – an organization that supports debates, the construction of activity, and the work of organization.Following this approach, our research was carried out during the implementation of a Shared Services Center in a large industrial group. A methodology for research and experimentation was defined based on the possibilities afforded by the context. This methodology includes three stages.The first stage analyzes the existing organization, identifies the issues that are not resolved by the organization, and characterizes the determinants of the contradictions which activity must confront. It highlights the fact that the organizational structure, designed by others, was imposed to its agents. Overall, the opportunities for choice, the scope of action, and the effective possibilities to carry out high-quality work diminish compared with the situation before the change. The second stage focuses on the ways in which operators attempt to redesign the organization in use. We then analyze the ways in which these attempts are discussed, as well as their costs and effects on the organizational structure. The emerging picture is that operators attempt to transform resources into capabilities, i.e. into genuine possibilities for producing work that is of the highest possible quality. To achieve this, the organization of work is altered; the procedures are questioned and circumvented: the “customer” is gradually transformed into a partner of the activity, but in a constrained, set environment. The third stage aims, based on the practices and wishes of the agents, to test a methodology for change in situ: the constructive co-analysis of work practices. This methodology aims to experiment an enabling organization and establish an enabling environment, supporting the deployment of activity and the success of operators. Visits are organized in order to invite each operator to observe the activity of his/her partner. The activity in the “here and now” constitutes an object of dialog, supporting a reflective practice on the joint collective activity and the transformation of rules and practices. Thus, the research-experimentation we have carried out has led to new organizational solutions and to setting the organization in motion.From there, development emerges as a goal and as a means for the action we have led. A diagnostic analysis allows us to identify what is allowing and hindering this development. The ergonomic action is then constructed so as to support this development throughout the course of and following this action. The thesis therefore takes its place within the project of constructive ergonomics, and the results obtained are discussed in the light of this project.

I prepared my thesis on Health Support at Workplaces under Particular Conditions of a Textile Factory. The main objective was to determine the company management?s activities in the field of health support. The second objective was to map the information provided to the staff on health support at the workplace, and the third objective was to propose the concept of a specific preventive programme. When preparing the concept of the preventive programme for the textile company I co-operated with the company management and with the company doctor. The reference group was represented by women employed in a textile plant in South Bohemia who worked in different workshops producing car seat covers, housing and children?s clothing. The work described in this thesis was carried out as quantitative research. For data collection I used anonymous questionnaires and the results of this research were plotted on graphs. The thesis is divided into a theoretical part and an empirical part. The theoretical part mainly deals with health support at the workplace, with an analysis of health risks at work including the impact of physical factors. At the beginning of the empirical part I set the goals and set out three hypotheses. Having analysed the collected data I found that H1, H2 and H3 were confirmed. The empirical section includes a description of the research technique which shows that more than 50 per cent of employees of the textile factory are overweight, then that there is a greater occurrence of health problems in the departments of sewing and embroidery machines and many women also had no idea of the meaning of health support at the workplace. According to the results it is possible to say that the textile company does not organize any physical activities or rehabilitative exercises for their employees. Based on the information I would recommend organizing sports courses, providing healthy canteen meals, reducing stress at the workplace and introducing dust extractors in order to reduce dust at the workplace. This thesis may bring the company better working comfort and help to improve the employees? health. The proposed preventive programme can also be a manual for employers in the textile plant in the field of health support at the workplace.

The employment of such techniques prompts profound transformations on both the project and work organization of the company that chooses to employ them. By this approach, companies that embrace the lean manufacturing model gain flexibility, acquire new principles, and adopt new techniques which enhance their manufacturing process management as well as their workforce management, supported upon the motivation of the worker as he performs his activities, upon team-work, and stimulated by qualification and engagement at work. The objective of this study is to deepen the knowledge of how workmen develop strategies and regulate work activities in productive situations that are planned and managed through principles and techniques based upon the lean manufacturing concept. In order to more clearly analyze the theme studied, a case study was conducted in the assembly line of a company that incorporated the lean manufacturing model to manage its manufacturing process. Work was analyzed through the analysis of activity, based on the precepts of the Ergonomic Analysis of Work. The case study certified that many aspects of the traditional assembly line remain evident in the lean assembly line; however, a new language is employed, due to the new culture and the more flexible model of lean manufacturing. Within the work situations that were analyzed in the case study, it was possible to establish some relevant aspects in the nature of regulations in which their relation to the lean techniques influence the strategies and operational modes of the workers during the process. Despite the diminishment of regulated space which takes place due to the application of lean manufacturing techniques, the operators continue to regulate work activities and fulfil production goals. / A utilização dos princípios e técnicas do modelo de produção enxuta tem crescido consideravelmente nas empresas nas últimas décadas. A ampliação da adoção das técnicas da produção enxuta nas empresas resulta em profundas transformações sobre o projeto e a organização do trabalho. Para essa abordagem, as empresas que adotam a produção enxuta passam a ser mais flexíveis, a ter novos princípios e a adotar novas técnicas na gestão da produção e da força de trabalho, apoiados na motivação do operário na execução de suas atividades, no trabalho em equipe, estimulados pelas qualificações e engajamento no trabalho. Diante disso, a ergonomia considera que as mudanças dos espaços de regulação fazem com que os trabalhadores adotem estratégias e modos operatórios a fim de regular seu estado interno e atingir os resultados esperados pela organização Esse estudo teve por objetivo aprofundar os conhecimentos sobre como os trabalhadores desenvolvem estratégias e regulam a atividade de trabalho em situações produtivas projetadas e geridas nos princípios e técnicas baseados na produção enxuta. Para melhor problematizar o tema estudado, foi realizado um estudo de caso em uma linha de montagem de uma empresa que adotou a produção enxuta como maneira de gerir a sua produção. O trabalho foi analisado utilizando como método a análise da atividade, apoiada nos pressupostos da Análise Ergonômica do Trabalho. No estudo de caso foi constatado que muitos aspectos da linha de montagem tradicional continuam evidentes na linha de montagem enxuta, porém utilizando-se de uma nova linguagem, devido à nova cultura, mais flexível do modelo de produção enxuta. Dentro das situações do trabalho analisado no estudo de caso foi possível constatar alguns aspectos relevantes na natureza das regulações, cuja relação com as técnicas enxutas influenciam nas estratégias e modos operatórios dos trabalhadores, durante o processo. Apesar da diminuição dos espaços de regulação com a utilização das técnicas da produção enxuta, os operadores, ainda assim, continuam a regular a atividade de trabalho e atingir os objetivos de produção.
