The stability constants of some lead(II)-ligand anion complexes already measured have been recalculated and others of some lead(II) and zinc(II) complexes have been measured by glass and chloride electrode potentiometry. These constants have been used in computer models of biological systems in order to assess the suitability of current and proposed therapeuticals as lead(II) sequestering agents in vivo. Glutathione is proposed as the most promising ligand for the treatment of plumbism. Thermodynamic functions for some lead(II)-ligand anion complexes have been determined, by calorimetry and temperature variation of formation constants, and from these some complex structures in aqueous solution have been suggested. The interaction of bovine serum albumin with lead(II) and copper(II) has been studied potentiometrically. The effect of some antirheumatoid arthritis drugs on the copper(II)-bovine serum albumin interaction has been observed by visible spectroscopy and molecular filtration. It is concluded that some of these drugs have the ability to release copper(II) from this protein bound situation. A contribution has been made to an interlaboratory potentiometric study of the nickel(II)-glycinate complexing system and a comparison of results from several laboratories is presented.

Os Planos Nacionais de Desenvolvimento 2006-2010 e 2010-2014 constituem a mais significativa fonte de informação sobre os elementos que possibilitam compreender a lógica institucional que dá origem às diretrizes da referida Política de geração de renda para população em pobreza extrema e deslocamento forçado, contida no “CONPES 3616”, de 2009. Neste documento, a inserção produtiva é considerada a estratégia mais acertada para a geração de renda, sendo os beneficiários reconhecidos por seu o “potencial produtivo”, o qual deve ser explorado para garantir a inserção no mercado. Identifica-se a tendência liberal nos postulados desta política, ao responsabilizar o pobre por sua situação de precariedade e, por desenvolver a sua própria iniciativa para superar a pobreza. À individualização e responsabilização soma-se, como consequência, a tendência à informalidade nas atividades produtivas desenvolvidas pelos beneficiários dos programas de geração de renda e, portanto, reproduz-se a precariedade laboral com que já convive a população em situação de pobreza e pobreza extrema. A “ajuda” institucional cumpre seu papel dinamizador do “potencial produtivo”, onde o Estado é o agente intermediador para lograr a transição do cidadão pobre à sua autonomia econômica e renda estável, podendo garantir a satisfação de suas necessidades e prescindir da tutela do Estado. A pesquisa aborda o enfoque qualitativo e a metodologia de estudo de caso. A principal técnica de coleta de dados, apoiou-se na revisão documental, mediante a pesquisa de dados disponíveis nos sites oficiais das entidades públicas encarregadas da execução, planejamento ou avaliação da Política de geração de renda, particularmente o Departamento de Prosperidad Social e Consejo Nacional de Política econômica e social CONPES. ___________________________________________________________________________ ABSTRACT / This study shows the analysis of the Statement of income generation established in Colombia with the change of social welfare policy social policy within the framework of social promotion. The National Development Plans 2006-2010 and 2010-2014 provide most of the elements to understand the institutional logic of the rise to the lineaments of income generation policy for the population in extreme poverty and forced displacement contained in CONPES 3616 2009. The productive inclusion is considered the most appropriate strategy to generate income, and those with beneficiaries of the "productive potential" that must be explored to ensure the inclusion in the market. It shows the liberal trend in the postulates of this policy in order to focus on the poor as responsible for their situation of precariousness and develop their own initiative to overcome poverty. In the individualization and accountability added up as a result of the trend toward informality in productive activities developed by beneficiaries of income generation programs and therefore, reproduce the job insecurity that is already own of the population in poverty and extreme poverty. Institutional aid fulfills its dynamic task of "productive potential", where the state is the intermediary agent to achieve the transition from poor to economic autonomy and stable income. With that the poor can ensure the satisfaction of their needs and do without state supervision. The research project will address the qualitative approach and case study methodology. The main data collection technique was the desk review through research data available on the official websites of responsible public with enforcement, planning or assessment of Statement of income generation, particularly the Department of Social Prosperity and Advice National de economic and social policy CONPES. Also, query normativity regarding the issue at hand.

This thesis is an examination of the problems confronting the young mother with small children today. The first section is concerned with methodology. It explains how the choice of subject was made; it describes how the study was designed, and it records how the sample was selected for the survey. The second section provides a historical background by discussing the various changes affecting the position of women in this country, during the last one hundred and fifty years. From the point of view of this survey, three major consequences are noted. 1. The status of women, in relation to men, has risen considerably. 2. The number of roles which women can perform, in society, have increased and become more varied. 3. Women have experienced an extension in the freedom of choice as to which roles they wish to perform. The third section is a discussion of the results of the interviews. These were conducted with forty eight middle class mothers and forty eight working class mothers. All the mothers in the survey were aged thirty or younger, and had at least one child under five. The most important facts to emerge are: 1. Some of the mothers, more particularly the working class mothers, felt themselves to be leading rather isolated lives. 2. At the time of the interview all the mothers saw their childrenas the central focus of their lives; the role of mother took precedence over all other roles. 3. At the same time the majority did not feel entirely at home in this role. Mothers, both working class and middle class, found themselves unprepared for the responsibilities of motherhood, and for the restrictions it imposed on their lives. 4. Both the middle class and the working class mothers had enlisted the support of their husbands in facing their problems. The middle class husband gave his support by co-operating with his wife in extending her interests outside the home and the children. The working class husband gave his support by devoting his leisure to sharing his wife's roles within the home, and participating regularly in all the household activities. 5. Ninety percent of the total sample was planning to work when the children were older. The significant factor here was thatthis return to work seemed an automatic process, the special decision was to remain at home. The wives in both samples were aware of the conflicts between the role of mother and the role of worker. On the other hand the great majority did not feel that a conflict existed between the role of wife and the role of worker. The concluding section considers the findings of the survey against the wider background of the position of women in this country today. It is suggested that mothers with young children have aspecial problem. There is a conflict of interests between the role of motherhood and the many other roles which women can perform today. The inability to resolve this conflict has meant that many mothers find themselves isolated, in a cul-de-sac, cut off from the central activities of society. In conclusion several methods of improving the situation are proposed: 1. A re-analysis of the education of girls. This would take as its starting point the fact that girls will be performing many different roles at different stages in their life. 'Home' or 'Work' should not be posed as mutually exclusive alternatives. The educational process itself should be divided into three stages. 1) School. 2) Further education or training. 3) Re-training for re-entry to work after a period of absence. 2. A re-examination of the roles and capacities of women as workers. In particular retraining schemes would have to be allied closely to work opportunities. Employers too would have to be educated in: 1) the real nature of women's capabilities, 2) the special problems that married women may encounter owing to their domestic responsibilities. 3. The re-direction of mothers and young children, back into the main stream of society. This could be done: 1) by the promotion of organisations parallel to the Parent Teacher Association, which give mothers the opportunity to relate to each other, to their local community, and to society at large. 2) by the general improvement in the facilities which society provides for young children. 3) by encouraging the community to include young children in a whole range of situations, from which, at present, they are excluded. The aim of all these proposals would be to enable mothers with small children to perform their traditional roles as mothers in ways that complemented rather than curtailed their other contemporary roles.

This study's objective was to uncover the role of fathers in constructing the spatial boundaries of their sons' childhoods and providing them access to play spaces, as informed by the fathers' memories of their own childhoods. In order to understand the meanings that fathers attribute to their experiences with boyhood worlds, ten semi-structured interviews were completed with fathers living in Ottawa. The fathers expressed uneasiness with what they perceive to be an increasing level of structure in their sons' play spaces. While most of the fathers attributed this decrease in autonomy to safety concerns for their sons, some fathers noted that organized play is in opposition with their experiential knowledge of boyhood in terms of risk and adventure. The study emphasizes the different ways in which fathers navigate through both societal expectations of good parenting and their understanding of masculinity as they create spatial worlds of boyhood for their sons.

The concept of a home is changing; away from the nuclear family, and towards the free-flowing collective of the commune. This thesis explores, in four parts, the new balance that must be found, between the individual and the commune. Firstly, we examine five architectural precedents. Exploring the architectural intent, use-case, and adaptation of the space, to find commonalities in their successes and failures. Secondly, we define three categories; Private, Protected, and Public; and use them to examine the spatial and relational hierarchy of association that private and public spaces require. Thirdly, combining these associations with the architectural precedents, we distill three communal archetypes: the Egalitarian, Familial, and Neighborly; exploring the hierarchy of association and relation that each creates diagrammatically and relationally. Fourthly, we design and model a commune of our own, combining a familial archetype with a rowhouse; which we explore specially and socially. / Master of Architecture / The concept of a home is changing; away from the traditional family, and towards the commune – a collection of individuals not necessarily related biologically. This thesis explores, in four parts, the design of individual and social spaces needed to create a successful commune. Firstly, we examine five historical examples to understand what made them succeed or fail, looking for similarities and differences in their design. Secondly, we define three categories; Private, Protected, and Public; and using them, explore private and public spaces, to understand the different requirements each has. Thirdly, using the historical examples, we divide communes into three types: the Egalitarian (where all are equal), the Familial (nested families), and the Neighborly (adjacent families) with diagrams and floorplans, to understand how the communes they create are different. Fourthly, we give life to a commune of our own, combining a familial commune type with a rowhouse architectural form, to create a vibrant colorful society, using a scale model to explore spatially and socially.
