Enabling Others in Social Work: Reflexivity and the Theory of Social Domains

This paper sets out a framework to structure reflexivity in social work practice. Based on the thinking of the sociologist, Derek Layder, it comprises five domains that impact on the individual and social life, namely: (i) psycho-biography – referring to a person’s unique experience throughout the life-course; (ii) situated activity – highlighting the impact of every day social interaction; (iii) social settings – addressing the role of organizations in social life; (iv) culture – covering the influence of attitudes, beliefs, tastes and ideas on symbolic meaning; and (v) politico-economy – alluding to the ramifications of political and economic forces on people’s lives. It is contended that power circulates throughout each domain as an enabling and constraining force. The paper then outlines a process for using the reflexive framework in ‘enabling’ activities such as practice learning, supervision, mentoring and coaching. By applying the framework in these contexts, it is argued that social workers can reflect critically on their role and develop emancipatory forms of practice.

Dietary habits of patients undergoing methadone therapy

OBJECTIVE: This study was designed to record the dietary habits of patients undergoing methadone therapy.

BACKGROUND: Numerous studies report that patients undergoing methadone treatment present with high levels of oral disease, especially dental caries. A number of factors have been described to account for this: sugared methadone preparations, prolonged oral retention, associated xerostomia and poor diet.

METHODS: A cross-sectional descriptive study using survey methodology was conducted of patients attending a non-resident drug rehabilitation clinic. A self-completion questionnaire and diet diary were developed and distributed to 66 patients over an 8 week period.

RESULTS: Of the 66 questionnaires distributed, 52 were successfully completed giving a response rate of 79%. 6 patients declined to complete the questionnaire. The surveyed patient pool consisted of 32 females (62%) and 20 males (38%) with a mean age of 32 years. All the participants were taking a prescribed daily dose of methadone when questioned. 68% of respondents consumed convience foods or sugary snacks every day. Of those patients who drank tea or coffee daily, 84% added sugar and 54% added 3 teaspoons or more. The majority of patients (71%) consumed at least one glass of a fizzy soft drink daily. In addition, the majority of respondents indicated that they snacked regularly between meals and 24% stated that they often woke up during the night for a snack. Patients recorded their last intake of food ranging from 5pm to 3am.

CONCLUSIONS: The patients surveyed had poor dietary habits. Respondents consumed a large amount of convience foods and sugars during mealtimes and through regular snacking. Dietary counselling should be considered as part of treatment for patients undergoing methadone therapy.

Thermal environments and comfort in dementia friendly dwellings

This study follows on from a research project that developed guidelines for the Universal Design (UD) of Dementia Friendly Dwellings for People with Dementia, their Families and Carers. Research findings point to the need for thermal environments that support people with dementia and do not provoke stress, agitation or anxiety. Using semi-structured interviews and qualitative analysis of people with dementia this paper aims to provide insight into the questions of appropriate thermal environments. The qualitative analysis is supported by example simulated indoor environment studies that investigate comfort in common thermal environment provision scenarios in the homes of people with dementia. This paper focuses on the thermal environment, its impact on people with dementia, its therapeutic value, and its role in encouraging engagement in every day activity.
Findings from the interviews emphasize that control over their own internal environment is a priority for people with dementia. A strong preference for naturally or passively conditioned environments over mechanical conditioning is evident. Preferences are expressed for naturally ventilated environments enabling occupant instigated air movement. Repeated emphasis is placed on familiar elements including the fire and hot water bottle. Little desire is expressed for information feedback or technological displays.

Privacy in next generation networks

In the modern society, communications and digital transactions are becoming the norm rather than the exception. As we allow networked computing devices into our every-day actions, we build a digital lifestyle where networks and devices enrich our interactions. However, as we move our information towards a connected digital environment, privacy becomes extremely important as most of our personal information can be found in the network. This is especially relevant as we design and adopt next generation networks that provide ubiquitous access to services and content, increasing the impact and pervasiveness of existing networks. The environments that provide widespread connectivity and services usually rely on network protocols that have few privacy considerations, compromising user privacy. The presented work focuses on the network aspects of privacy, considering how network protocols threaten user privacy, especially on next generation networks scenarios. We target the identifiers that are present in each network protocol and support its designed function. By studying how the network identifiers can compromise user privacy, we explore how these threats can stem from the identifier itself and from relationships established between several protocol identifiers. Following the study focused on identifiers, we show that privacy in the network can be explored along two dimensions: a vertical dimension that establishes privacy relationships across several layers and protocols, reaching the user, and a horizontal dimension that highlights the threats exposed by individual protocols, usually confined to a single layer. With these concepts, we outline an integrated perspective on privacy in the network, embracing both vertical and horizontal interactions of privacy. This approach enables the discussion of several mechanisms to address privacy threats on individual layers, leading to architectural instantiations focused on user privacy. We also show how the different dimensions of privacy can provide insight into the relationships that exist in a layered network stack, providing a potential path towards designing and implementing future privacy-aware network architectures.

Biodiesel fuel formulation

O consumo de energia a nível mundial aumenta a cada dia, de forma inversa aos recursos fósseis que decrescem de dia para dia. O sector dos transportes é o maior consumidor deste recurso. Face ao actual cenário urge encontrar uma solução renovável e sustentável que permita não só, diminuir a nossa dependência de combustíveis fósseis mas fundamentalmente promover a sua substituição por energias de fontes renováveis. O biodiesel apresenta-se na vanguarda das alternativas aos combustiveis derivados do petróleo, para o sector dos transportes, sendo considerado uma importante opção a curto prazo, uma vez que o seu preço pode ser competitivo com o diesel convencional, e para a sua utilização o motor de combustão não necessita de alterações. O biodiesel é uma mistura líquida, não tóxica, biodegradável de ésteres de ácidos gordos, sem teor de enxofre ou compostos aromáticos, apresenta boa lubricidade, alto número de cetano, e origina emissões gasosas mais limpas. O presente trabalho contribui para um melhor conhecimento da dependência das propriedades termofisicas do biodiesel com a sua composição. A publicação de novos dados permitirá o desenvolvimento de modelos mais fiáveis na previsão do comportamento do biodiesel. As propriedades densidade e viscosidade são o espelho da composição do biodiesel, uma vez que dependem directamente da matéria prima que lhe deu origem, mais do que do processo de produção. Neste trabalho os dados medidos de densidade e viscosidade de biodiesel foram testados com vários modelos e inclusivamente foram propostos novos modelos ajustados para esta família de compostos. Os dados medidos abrangem uma ampla gama de temperaturas e no caso da densidade também foram medidos dados a alta pressão de biodiesel e de alguns ésteres metilico puros. Neste trabalho também são apresentados dados experimentais para o equilíbrio de fases sólido-liquído de biodiesel e equlibrio de fases líquidolíquido de alguns sistemas importantes para a produção de biodiesel. Ambos os tipos de equilíbrio foram descritos por modelos desenvolvidos no nosso laboratório. Uma importância especial é dado aqui a propriedades que dependem do perfil de ácidos gordos da matéria-prima além de densidade e viscosidade; o índice de iodo e temperature limite de filtrabalidade são aqui avaliados com base nas considerações das normas. Os ácidos gordos livres são um sub-produto de refinação de óleo alimentar, que são removidos na desodoração, no processo de purificação do óleo. A catálise enzimática é aqui abordada como alternativa para a conversão destes ácidos gordos livres em biodiesel. Estudou-se a capacidade da lipase da Candida antartica (Novozym 435) para promover a esterificação de ácidos gordos livres com metanol ou etanol, utilizando metodologia de superfície de resposta com planeamento experimental. Avaliou-se a influência de diversas variáveis no rendimento da reacção.

Environmental Implications of Hotel Growth in China: Integrating Sustainability with Hotel Development

China has embarked on the largest program of new hotel construction the world has ever seen. Even though the nation’s growth rate has eased somewhat in the past year, China’s hotel development continues at a pace that would see at least three new 150+ room hotels open every day for the next 25 years.1 Even if the industry does not continue to expand at this rate, China’s hotel growth carries substantial consequences in terms of increases in energy and water consumption, and an expanding carbon footprint. In this paper, we outline the dimensions of this issue, and we urge hotel developers to heed the national government’s push for greater sustainability.

D. João de Magalhães e Avelar e a Fundação da Real Biblioteca Pública Municipal do Porto (1833)

D. João de Magalhães e Avelar (1754-1833) formou aquela que, ao tempo, era a maior biblioteca privada portuguesa. Com cerca de 36000 volumes, foi elogiada por personalidades nacionais e estrangeiras, por aliar à quantidade de volumes inúmeros e valiosíssimos manuscritos. Formada ao longo dos séculos XVIII e XIX, durante mais de 30 anos, originou, em 1833, o primeiro núcleo da actual Biblioteca Pública Municipal do Porto. Numa época em que possuir livros era sinónimo de prestígio social mas num período em que quase não havia tradição de bibliotecas públicas no nosso país, contrariamente ao que acontecia noutras realidades, a livraria privada de Avelar formou, com outras, a Real Biblioteca Pública da Cidade do Porto. Em 1833, aquando do primeiro aniversário da entrada do exército liberal no Porto, por decreto, criou-se a biblioteca portuense. Estabelecida na casa que servia de Hospício dos Religiosos de Santo António do Val da Piedade, à praça da Cordoaria, tinha como objectivo satisfazer a utilidade pública, estando aberta todos os dias, excepto domingos e feriados. Propriedade da cidade do Porto, ficava sujeita à administração da Câmara que se obrigava à sua guarda, manutenção, conservação, bem como à constante aquisição de espólio. Como veremos, tratou-se de um processo conflituoso mas o Porto obtinha, definitivamente, a sua biblioteca pública.

How new online communication tools and the availability of content influence the audiences and the creative process

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.
