Adaptação do modelo ABCDE para comunicar a má notícia ao proprietário do paciente oncológico em medicina veterinária

Introdução: À semelhança do que ocorre na Medicina Humana, também em Medicina Veterinária, a prevalência da doença oncológica em animais de companhia tem vindo a aumentar significativamente. Desenvolvimento: A evolução da Medicina Veterinária, nas últimas décadas, veio trazer mudança nos paradigmas clínicos, nomeadamente no respeitante à relação com o animal mas também com o proprietário. Sendo a oncologia a especialidade em que há maior probabilidade de ter que comunicar uma má notícia, neste trabalho propõe-se a adaptação do modelo ABCDE da Medicina Humana para a Medicina Veterinária. Conclusões: A adaptação do modelo ABCDE para a Medicina Veterinária permite melhorar a comunicação com o proprietário cuidador e dotar os profissionais da equipe Médica Veterinária de melhores competências.

The Weight of Language and Action: Epistemic Stance, Methodological Action,and Theoretical Perspective in Knowledge Organization

Knowledge organization (KO) research is a field of scholarship concerned with the design, study and critique of the processes of organizing and representing documents that societies see as worthy of preserving (Tennis, 2008). In this context we are concerned with the relationship between language and action.On the one hand, we are concerned with what language can and does do for our knowledge organization systems (KOS). For example, how do the words NEGRO or INDIAN work in historical and contemporary indexing languages? In relation to this, we are also concerned with how we know about knowledge organization (KO) and its languages. On the other hand, we are concerned with how to act given this knowledge. That is, how do we carry out research and how do we design, implement, and evaluate KO systems?It is important to consider these questions in the context of our work because we are delegated by society to disseminate cultural memory. We are endowed with a perspective, prepared by an education, and granted positions whereby society asks us to ensure that documentary material is accessible to future generations. There is a social value in our work, and as such there is a social imperative to our work. We must act with good conscience, and use language judiciously, for the memory of the world is a heavy burden.In this paper, I explore these two weights of language and action that bear down on KO researchers. I first summarize what extant literature says about the knowledge claims we make with regard to KO practices and systems. To make it clear what it is that I think we know, I create a schematic that will link claims (language) to actions in advising, implementing, or evaluating information practices and systems.I will then contrast this with what we do not know, that is, what the unanswered questions might be (Gnoli, 2008 ; Dahlberg, 2011), and I will discuss them in relation to the two weights in our field of KO.Further, I will try to provide a systematic overview of possible ways to address these open questions in KO research. I will draw on the concept of elenchus - the forms of epistemology, theory, and methodology in KO (Tennis, 2008), and framework analysis which are structures, work practice, and discourses of KO systems (Tennis, 2006). In so doing, I will argue for a Neopragmatic stance on the weight of language and action in KO (Rorty, 1982 ; 2000). I will close by addressing the lacuna left in Neopragmatic thought – the ethical imperative to use language and action in a particular good and moral way. That is, I will address the ethical imperative of KO given its weights, epistemologies, theories, and methods. To do this, I will review a sample of relevant work on deontology in both western and eastern philosophical schools (e.g., Harvey, 1995).The perspective I want to communicate in this section is that the good in carrying out KO research may begin with epistemic stances (cf., language), but ultimately stands on ethical actions. I will present an analysis describing the micro and the macro ethical concerns in relation to KO research and its advice on practice. I hope this demonstrates that the direction of epistemology, theory, and methodology in KO, while burdened with the dual weights of language and action, is clear when provided an ethical sounding board. We know how to proceed when we understand how our work can benefit the world.KO is an important, if not always understood, division of labor in a society that values its documentary heritage and memory institutions. Being able to do good requires us to understand how to balance the weights of language and action. We must understand where we stand and be able to chart a path forward, one that does not cause harm, but adds value to the world and those that want to access recorded knowledge.

La actualización del modelo socialista y sus efectos en el Partido Comunista Cubano

El VI Congreso del Partido Comunista de Cuba introdujo una nueva agenda económica que el Gobierno llama la actualización del modelo socialista. Muchos piensan que en esencia se trata de una serie de reformas y reducen su importancia a su dimensión económica. Esta monografía busca explicar la actualización aplicando el análisis de sistemas-mundo de Immanuel Wallerstein, aportando una interpretación no convencional del fenómeno. Se puntualizará en las variables de poder y en los actores políticos que han determinado la nueva política económica: el Partido Comunista de Cuba (PCC) y las Fuerzas Armadas Revolucionarias (FAR). Ambos conforman lo que Wallerstein denomina un movimiento antisitémico. El argumento principal es que el movimiento ha puesto en marcha las reformas buscando fortalecer el Estado y así garantizar su supervivencia al consolidar su posición como el competidor único del poder estatal. Como se verá, estas metas han llevado al movimiento a sacrificar parte de su naturaleza antisistémica.

Validity and reliability of the international fItness scale (IFIS) in a population-based sample of schoolchildren in Bogota, Colombia: The FUPRECOL study

The International FItness Scale (IFIS) is a self-reported measure of physical fitness that could easily. This scale has been validated in children, adolescents, and young adults; however, it is unknown whether the IFIS represents a valid and reliable estimate of physical fitness in Latino-American youth population. In the present study we aimed to examine the validity and reliability of the IFIS on a population-based sample of schoolchildren in Bogota, Colombia. Participants were 1,875 Colombian youth (56.2% girls) aged 9 to 17.9 years old. We measured adiposity markers (body fat, waist-to-height ratio, skinfold thicknesses and BMI), blood pressure, lipids profile, fasting glucose, and physical fitness level (self reported and measured). Also, a validated cardiometabolic risk index was used. An age- and sex-matched sample of 229 Schoolchildren originally not included in the study sample fulfilled IFIS twice for reliability purposes. Our data suggest that both measured and self-reported overall fitness were associated inversely with adiposity indicators and a cardiometabolic risk score. Overall, schoolchildren who self-reported “good” and “very good” fitness had better measured fitness than those who reported “very poor” and “poor” fitness (all p<0.001). Test–retest reliability of IFIS items was also good, with an average weighted Kappa of 0.811. Therefore, our findings suggest that self-reported fitness, as assessed by IFIS, is a valid, reliable, and health-related measure, and it can be a good alternative for future use in large studies with Latin-schoolchildren from Colombia.

Value in Social Marketing : A Qualitative exploration within government health services

Value creation is an area with long-standing importance in the marketing field, yet little is known about the value construct itself. In social marketing, value can be regarded as an incentive for consumers to perform desirable behaviours that lead to bother greater social good and individual benefit. An understanding of customer value in the consumption of social products is an important aspect of designing social marketing interventions that can effectively change social behaviours. This paper uses qualitative data, gathered during depth interviews, to explore the value dimensions women experience from using government-provided breast screening services every two years. Thematic analysis was used in discovering that emotional functional, social and altruistic dimensions of value were present in womens’ experiences with these services as well as in the outcomes from using them.

Asia

Reporters sans frontiéres (RSF) has repeatedly declared Asia to be the most demanding continent for journalists and their news organizations to operate in, and in some countries, even simply to survive in. The many reports issued by RSF and other global agencies regularly show Asia to be the region in which the largest number of murders of journalists occur per year, even when Asian–Arabic states and Central Asia are not included in the definition of ‘Asia’. The reports describe numerous physical, legal and economic threats as well as serious political repression and restrictions that journalists face as they attempt to function as watch-dogs, agenda-setters and gate-keepers for their societies. The statistics and examples provided within these reports, however, do not provide the full picture. Most Asian nations also host vibrant media cultures in which journalists play an important role in supporting social and democratic processes and activities. This chapter outlines the political and economic influences on Asian journalism; the impact of new technologies; the debates about philosophies such as 'development journalism', 'peace journalism' and 'Asian values'; and the influence of the so-called 'envelope culture' or practices of gift-giving and bribery that pervade journalism in some countries. To illustrate how these principles affect journalists' practice, the chapter presents a comparison of the starkly contrasting situations in India versus North Korea (Democratic People's Republic of Korea). The chapter also describes issues affecting countries as far afield as China to Kazakhstan, including a short case study of journalism during the so-called Saffron Revolution in Burma in 2007. The chapter concludes with suggestions about how training and aid for the Asian should be contextualized to take into account the specific cultural, economic and political factors that shape and limit the media’s performance, and how journalists might be best placed to negotiate around them. Such training needs to be sensitive to valid variations in perceptions of what kind of governance and journalism best serves development, without serving politically motivated rhetoric.

Do derivatives have a role in the risk-shifting behaviour of fund managers?

In this paper we examine the extent to which derivatives are used to affect the risk-shifting behaviour of Australian equity fund managers. We find, after periods of good and poor performance, the risk-shifting behaviour of fund managers is different between derivative users and non-users. Our results support the gaming and active competition hypotheses but there is little support for the cash flow hypothesis. The study also allows for a complex reporting environment by analysing data across three alternate time periods: the calendar year, financial year and quarterly frames. Given that our results are not consistent across time periods for users and non-users of derivatives, some caution in interpretation is required.

The mobile phone as a multi OTP device using trusted computing

The rapid growth in the number of online services leads to an increasing number of different digital identities each user needs to manage. As a result, many people feel overloaded with credentials, which in turn negatively impact their ability to manage them securely. Passwords are perhaps the most common type of credential used today. To avoid the tedious task of remembering difficult passwords, users often behave less securely by using low entropy and weak passwords. Weak passwords and bad password habits represent security threats to online services. Some solutions have been developed to eliminate the need for users to create and manage passwords. A typical solution is based on giving the user a hardware token that generates one-time-passwords, i.e. passwords for single session or transaction usage. Unfortunately, most of these solutions do not satisfy scalability and/or usability requirements, or they are simply insecure. In this paper, we propose a scalable OTP solution using mobile phones and based on trusted computing technology that combines enhanced usability with strong security.

An intelligent data mining technique for product quality improvement

Advances in data mining have provided techniques for automatically discovering underlying knowledge and extracting useful information from large volumes of data. Data mining offers tools for quick discovery of relationships, patterns and knowledge in large complex databases. Application of data mining to manufacturing is relatively limited mainly because of complexity of manufacturing data. Growing self organizing map (GSOM) algorithm has been proven to be an efficient algorithm to analyze unsupervised DNA data. However, it produced unsatisfactory clustering when used on some large manufacturing data. In this paper a data mining methodology has been proposed using a GSOM tool which was developed using a modified GSOM algorithm. The proposed method is used to generate clusters for good and faulty products from a manufacturing dataset. The clustering quality (CQ) measure proposed in the paper is used to evaluate the performance of the cluster maps. The paper also proposed an automatic identification of variables to find the most probable causative factor(s) that discriminate between good and faulty product by quickly examining the historical manufacturing data. The proposed method offers the manufacturers to smoothen the production flow and improve the quality of the products. Simulation results on small and large manufacturing data show the effectiveness of the proposed method.

Reference bias : presentation of extreme health states prior to EQ-VAS improves health-related quality of life scores. A randomised crossover trial.

Background: Clinical practice and clinical research has made a concerted effort to move beyond the use of clinical indicators alone and embrace patient focused care through the use of patient reported outcomes such as healthrelated quality of life. However, unless patients give consistent consideration to the health states that give meaning to measurement scales used to evaluate these constructs, longitudinal comparison of these measures may be invalid. This study aimed to investigate whether patients give consideration to a standard health state rating scale (EQ-VAS) and whether consideration of good and poor health state descriptors immediately changes their selfreport. Methods: A randomised crossover trial was implemented amongst hospitalised older adults (n = 151). Patients were asked to consider descriptions of extremely good (Description-A) and poor (Description-B) health states. The EQ-VAS was administered as a self-report at baseline, after the first descriptors (A or B), then again after the remaining descriptors (B or A respectively). At baseline patients were also asked if they had considered either EQVAS anchors. Results: Overall 106/151 (70%) participants changed their self-evaluation by ≥5 points on the 100 point VAS, with a mean (SD) change of +4.5 (12) points (p < 0.001). A total of 74/151 (49%) participants did not consider the best health VAS anchor, of the 77 who did 59 (77%) thought the good health descriptors were more extreme (better) then they had previously considered. Similarly 85/151 (66%) participants did not consider the worst health anchor of the 66 who did 63 (95%) thought the poor health descriptors were more extreme (worse) then they had previously considered. Conclusions: Health state self-reports may not be well considered. An immediate significant shift in response can be elicited by exposure to a mere description of an extreme health state despite no actual change in underlying health state occurring. Caution should be exercised in research and clinical settings when interpreting subjective patient reported outcomes that are dependent on brief anchors for meaning.

On location : the imagined private interior in public life

This paper reveals the interior landscapes of selected contemporary Australian films, such as The Caterpillar Wish and Bad Boy Bubby, to develop a number of thematic influences on the manner in which domestic and private lives are constructed through filmic imagination. The research uncovers the conditions that contribute to particular scenographic representations of the humble interiors that act as both backdrop and performer to subtle and often troubled narratives. Such readings are informed by the theoretical works of writer Gertrude Stein, among others, who explore the relationships between the scenographic third dimension and the fourth dimensional performance in the representation of narrative space. A further theoretical thread lies in Giuliana Bruno’s work on the tension between private and public filmic space, which is explored through the public outing of intensely private spaces generated through narratives framed by the specificities of found interiors. Beyond the interrogation of qualities of imagined filmic space is the condition whereby locations, once transformed by the event of movie making are consequently forever revised. These altered conditions subsequently reinvest the lives of those who return to the location with layered narratives of occupation. Situationally, the now reconverted interior performs as contributor to subsequent private inhabitation, even if only as imagined space. The possibility here is that the qualities of the original may be superimposed and recontextualised to invest post-produced interiors with the qualities of the other space as imagined. This reading of film space explores new theoretical design scenarios for imagined and everyday interior landscapes.
