A reconstrução do papel do professor para os contextos educacionais presencial e a distância

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção.Este trabalho se propõe a estudar a reconstrução do papel do professor para os contextos educacionais presencial e a distância, a partir da implantação do Ambiente de Aprendizagem Colaborativa a Distancia Eureka na Pontifícia Universidade Católica do Paraná, no período de outubro a dezembro de 2001. Os objetivos pretendidos são a identificação das diferenças básicas entre os contextos educacionais presencial e a distância, a identificação do papel do professor nesses contextos e a reflexão sobre qual deve ser a formação do professor atual

Queering Addiction

Much has been written about the subject of addiction, but very little has been written from a queer feminist standpoint. Most of the work available concerning addiction is aimed primarily at a clinical audience, those interested in treating people with addictions. Most non-clinical work is aimed predominantly at people who are either suffering from addiction themselves or close to someone dealing with addiction. In pursuing this thesis project, I want to add the queer feminist discourse as well as a disability discourse to the larger public dialogue on the addict’s embodied identity. I am proposing that the addict’s perspective is a valuable resource that can give voice to the often unmentionable. Addicts often negotiate with norms. It is here that we witness their attempts to create a sense of an embodied normative self-identity. These sought-after self-identities come with bodily limitations and histories through which the addict has been medicalized and pathologized. In this sense, addicts challenge universalizing norms even while they repeatedly experience extreme levels of discrimination, violence, and intolerance. In looking at the continuity between life-making and the wearing down of an addict’s embodied identities through engagement with sites of administration, discipline, and measure, the addict’s self-identity remains tangled in a complicated web of assumptions about a healthy life, as well as about moral ability to generate self-capacity. Unraveling the addict perspective on self-identity can offer us an understanding of selfhood that is about learning to live with a limited self and body. Thus, the addict’s identity making is a matter of queering the body as well as engaging a disability perspective. Along with making use of queer theory and disability discourse, I will take my own embodied self-identity as an example of an addict in order to render the knowledge that regulates, controls, and manages marginalized bodies, both ideologically and materially. I will further reflect on the multi-layered manifestations of power and emotion, or affect, that comprise the experience of the addict’s embodiment. Weaving together a personal narrative of addiction and recovery with academic discourses—contemporary queer, feminist, and disability discourse—I will situate the addicts’ perspective alongside these other prominent theoretical perspectives

Motivating the formation of partnerships by small water systems

Small community water systems (CWS) often have difficulty maintaining high-quality service provision. Partnerships can help alleviate these problems, yet may not be attainable or pursued. This research examines the perspectives of U.S. state agencies with drinking water primacy regarding the benefits of water systems partnerships and the points of leverage that can induce water systems to partner. It assesses the benefits, drawbacks, and barriers to five common forms of partnerships as well as the approaches states can use to encourage small CWS partnerships. Findings indicate that while partnerships hold significant potential, in many contexts, there are inherent limitations to their formation

Assessment of Microbiologically Influenced Corrosion Potential in the International Space Station Internal Active Thermal Control System Heat Exchanger Materials: A 6-Momths Study

The fluid in the Internal Active Thermal Control System (IATCS) of the International Space Station (ISS) is water based. The fluid in the ISS Laboratory Module and Node 1 initially contained a mix of water, phosphate (corrosion control), borate (pH buffer), and silver sulfate (Ag2SO4) (microbial control) at a pH of 9.5+/-0.5. Over time, the chemistry of the fluid changed. Fluid changes included a pH drop from 9.5 to 8.3 due to diffusion of carbon dioxide (CO2) through Teflon(reistered Trademark) (DuPont) hoses, increases in dissolved nickel (Ni) levels, deposition of silver (Ag) to metal surfaces, and precipitation of the phosphate (PO4) as nickel phosphate (NiPO4). The drop in pH and unavailability of a antimicrobial has provided an environment conducive to microbial growth. Microbial levels in the fluid have increased from >10 colony-forming units (CFUs)/100 ml to 10(exp 6) CFUs/100 ml. The heat exchangers in the IATCS loops are considered the weakest point in the loop because of the material thickness (=7 mil). It is made of a Ni-based braze filler/CRES 347. Results of a preliminary test performed at Hamilton Sundstrand indicated the possibility of pitting on this material at locations where Ag deposits were found. Later, tests have confirmed that chemical corrosion of the materials is a concern for this system. Accumulation of micro-organisms on surfaces (biofilm) can also result in material degradation and can amplify the damage caused by the chemical corrosion, known as microbiologically influenced corrosion (MIC). This paper will discuss the results of a 6-mo test performed to characterize and quantify the damage from microbial accumulation on the surface of the ISS/ATCS heat exchanger materials. The test was designed to quantify the damage to the materials under worst-case conditions with and without micro-organisms present at pH 8.3 and 9.5
