Focused molecular analysis of small cell lung cancer: feasibility in routine clinical practice.

Background: There is an urgent need to identify molecular signatures in small cell lung cancer (SCLC) that may select patients who are likely to respond to molecularly targeted therapies. In this study, we investigate the feasibility of undertaking focused molecular analyses on routine diagnostic biopsies in patients with SCLC.

Methods: A series of histopathologically confirmed formalin-fixed, paraffin-embedded SCLC specimens were analysed for epidermal growth factor receptors (EGFR), KRAS, NRAS and BRAF mutations, ALK gene rearrangements and MET amplification. EGFR and KRAS mutation testing was evaluated using real time polymerase chain reaction (RT-PCR cobas®), BRAF and NRAS mutations using multiplex PCR and capillary electrophoresis-single strand conformation analysis, and ALK and MET aberrations with fluorescent in situ hybridization. All genetic aberrations detected were validated independently.

Results: A total of 105 patients diagnosed with SCLC between July 1990 and September 2006 were included. 60 (57 %) patients had suitable tumour tissue for molecular testing. 25 patients were successfully evaluated for all six pre-defined molecular aberrations. Eleven patients failed all molecular analysis. No mutations in EGFR, KRAS and NRAS were detected, and no ALK gene rearrangements or MET gene amplifications were identified. A V600E substitution in BRAF was detected in a Caucasian male smoker diagnosed with SCLC with squamoid and glandular features.

Conclusion: The paucity of patients with sufficient tumour tissue, quality of DNA extracted and low frequency of aberrations detected indicate that alternative molecular characterisation approaches are necessary, such as the use of circulating plasma DNA in patients with SCLC.

Only Time Will Tell: The Changing Relationships between LMX, Job Performance, and Justice

Although it has been argued that LMX is a phenomenon that develops over time, the existing LMX literature is largely cross-sectional in nature. Yet, there is a great need for unraveling how LMX develops over time. To address this issue in the LMX literature, we examine the relationships of LMX with two variables known for changing over time: job performance and justice perceptions. On the basis of current empirical findings, a simulation deductively shows that LMX develops over time, but differently in early stages versus more mature stages. Our findings also indicate that performance and justice trends affect LMX. Implications for LMX theory, and for longitudinal research on LMX, performance, and justice are discussed.

“Medical bag for General Practice” Just in Case: redesigning the doctor’s bag (2012)

This research addressed practice related problems from a medico-legal perspective and aims to provide a working tool that aids GPs to comply with best practice protocols. The resulting bag was developed in collaboration with General Practitioners, clinicians and members of the Medical Defense Union. Using proven methods developed within the Healthcare & Patient Safety Lab (e.g. DOME, Ambulance) to establish an evidence-based brief, this research used task, equipment and consumables analysis to determine minimum requirements and preferred layouts for task optimisation. The research established that clinicians require three distinct functions in their workspace: laying out, organisation and information retrieval. Feedback from clinicians indicates that this working tool allows them to access information and equipment wherever they may be and suggests an improvement from current practice. The research is now into a second year where the design of the bag will be refined and tested. Lifestyle and demographic changes such as the ageing population and increased prevalence of chronic diseases require more consistent standards of primary care, and care that is well coordinated and integrated (Imison, et al., 2011). Many guidelines exist relating to general practice and the doctor’s bag (NSLMC, 2008, RACGP, 2010, RCGP, 2008 and Hiramanek, 2004), however there is no standard in the UK that regulates the shape and materials of the bag or its contents. Doctors may use any sort of vessel to transport their equipment and consumables to a patient’s location. Furthermore, treating a patient in their own home, outside an ideal clinical environment, presents its own complications. A looks-like, works-like bag prototype and information system that will be used in clinical trials, the results of which will determine the manufacturing of a new, standardised bag for clinical treatment used by members of the Medical Defence Union.

Gaining by Giving? Peer Research into Service User and Carer Perceptions of Inclusivity in Higher Education

Service users and carers (SUAC) have made significant contributions to professional training in social work courses in Higher Education (HE) over the past decade in the UK. Such participation has been championed by government, academics and SUAC groups from a range of theoretical and political perspectives. Most research into the effectiveness of SUAC involvement at HE has come from the perspectives of academics and very little SUAC-led research exists. This qualitative peer research was led by two members of the University of Worcester’s SUAC group. Findings were that SUAC perceived their involvement brought benefits to students, staff, the University and the local community. Significant personal benefits such as finding a new support network, increased self-development and greater confidence to manage their own care were identified in ways that suggested that the benefits that can flow from SUAC involvement at HE are perhaps more far-reaching than previously recognised. Barriers to inclusion were less than previously reported in the literature and the humanising effects of SUAC involvement are presented as a partial antidote to an increasingly marketised HE culture.

Occupational therapists’ perceptions of occupation in practice : an exploratory study

Medications, youth therapeutic cultures and performance consumptions: a sociological approach

This article analyses performance consumptions among young people. The theme is explored along two main axes. The first concerns the social heterogeneity in this field, considered on two levels: the different purposes for those investments - cognitive/mental and physical performance; and the different social contexts - university and work - where performance practices and dispositions may be fostered. The second axis explores the roles of pharmacological and natural consumptions, and their interrelationship, in the dissemination of these practices. The empirical data for this analysis were drawn from an ongoing research project on performance consumptions among young people (aged 18-29 years) in Portugal, including both university students and young workers without university education. The results correspond to the stage of extensive research, for which a questionnaire was organised at a national level, using non-proportional quota sampling. On the one hand, they show that (a) there is a hierarchy of acceptance of consumptions according to their purposes, with cognitive/mental performance showing higher acceptance and (b) both pharmaceuticals and natural products are consumed for every type of performance investment. On the other, the comparison between students and workers introduces a certain heterogeneity in this general backdrop, both in terms of the purposes for their consumptions and their opting for natural or pharmacological resources. These threads of heterogeneity will prompt a discussion of the dynamics of pharmaceuticalisation within the field of performance, in particular how therapeutic cultures may be changing in terms of the way individuals relate to medications, expanding their uses in social life.

Dancing the Archive: Rhythms of Change in Post-Volcano Identities on Montserrat, West Indies

In this dissertation, I demonstrate how improvisations within the structures of performance during Montserrat’s annual festivals produce “rhythms of change” that contribute to the formation of cultural identities. Montserrat is a small island of 39.5 square miles in the Caribbean’s Leeward Islands, and a volcanic disaster in the 1990s led to the loss of villages, homes, and material possessions. The crisis resulted in mass displacement and emigration, and today’s remaining population of 5,000 is now in a stage of post-volcano redevelopment. The reliability of written archives for establishing cultural knowledge is tenuous, and the community is faced with re-energizing cherished cultural traditions. This ethnographic research traces my embodied search for Montserrat’s history through an archive that is itself intangible and performative. Festivals produce some of the island’s most visible and culturally political events, and music and dance performances prompt on- and off-stage discussions about the island’s multifaceted heritage. The festival cycle provides the structure for ongoing renegotiations of what it means to be “Montserratian.” I focus especially on the island’s often-discussed and debated “triangular” heritage of Irishness, Africanness, and Montserratianness as it is performed during the festivals. Through my meanderings along the winding hilly roads of Montserrat, I explored reconfigurations of cultural memory through the island’s masquerade dance tradition and other festival celebrations. In this work, I introduce a “Cast of Characters,” each of whose scholarly, artistic, and public service work on Montserrat contributes to the shape and transformation of the island’s post-volcano cultural identities today. This dissertation is about the kinesthetic transmission of shared (and sometimes unshared) cultural knowledge, the substance of which echoes in the rhythms of Montserrat’s music and dance practices today.

Multijurisdictional fisheries performance reporting: How Australia’s nationally standardised approach to assessing stock status compares

Australian marine wild-capture fisheries are managed by eight separate jurisdictions. Traditionally, fishery status reports have been produced separately by most of these jurisdictions, assessing the fish stocks they manage, and reporting on the effectiveness of their fisheries management. However, the format, the type of stock status assessments, the thresholds and terminology used to describe stock status and the classification frameworks have varied over time and among jurisdictions. These differences complicate efforts to understand stock status on a national scale. They also create potential misunderstanding among the wider community about how to interpret information on the status of fish stocks, and the fisheries management and science processes more generally. This is especially true when considering stocks that are shared across two or more jurisdictional boundaries. A standardised approach was developed in 2011 leading to production of the first national Status of key Australian fish stocks reports in 2012, followed by a second edition in 2014 (www.fish.gov.au). Production of these reports was the first step towards a broader national approach to reporting on the performance of Australian fisheries for target species and for wider ecosystem and socioeconomic consequences. This paper outlines the challenges associated with moving towards national performance reporting for target fish stocks and Australia’s successes so far. It also outlines the challenges ahead, in particular those relating to reporting more broadly on the status of entire fisheries. Comparisons are drawn between Australia and New Zealand and more broadly between Australia and other countries.

Relatório de estágio

O presente relatório de estágio configura-se como o requisito parcial para a obtenção do grau de mestre em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico. Apresenta o objetivo fulcral de refletir, de forma indagadora e problematizadora, sobre o desenvolvimento profissional da mestranda, emergente da concretização do estágio profissionalizante nos contextos de Educação Pré-Escolar e 1.º Ciclo do Ensino Básico. No relatório serão abordados quais os pressupostos teóricos e legais que fundamentaram a prática pedagógica da mestranda em ambos os níveis educativos, assim como o modo como estes foram mobilizados pela mesma. A metodologia de investigação-ação constituiu o pilar do desenvolvimento profissional, pessoal e social da formanda, possibilitando que esta adotasse uma postura investigativa, crítica e reflexiva, com vista ao melhoramento do processo de ensino e aprendizagem. Nesta linha de raciocínio, a ação educativa desenvolvida pela mestranda obedeceu a um processo cíclico, através da articulação das etapas de observação, planificação, ação, reflexão e avaliação. Importa salientar, ao longo do estágio, a mestranda procurou que a sua ação pedagógica mobilizasse características inerentes ao paradigma socio construtivista, no qual a criança desempenha o papel crucial na ação. Face ao exposto, o estágio profissionalizante desenvolvido em ambos os contextos educativos caracterizou-se por ser a força motriz para que a mestranda desenvolvesse, construtivamente, as competências profissionais inerentes a um perfil docente duplo. Assim, a mestranda tomou consciência acerca das semelhanças e contrastes evidenciados pelos dois níveis educativos, valorando a importância de uma sequencialidade entre estes. Em suma, a formação permitiu o início da aprendizagem do que é ser educador e professor e a consciencialização da essência da missão de educar.

EXPLORING VIENNESE TUNING AND ITS BENEFITS FOR THE MODERN DOUBLE BASSIST

The role of the double bass in Vienna during the eighteenth century evolved significantly between 1760 and 1812. During these years, Viennese composers began to view the double bass less as an accompanimental instrument and more as a solo voice. Despite the abundance of music written for the double bass during this time, few of these compositions are regularly performed today. This dissertation serves three purposes. I explore how learning eighteenth-century Viennese compositions in the original tuning can influence modern performances of these works. Secondly, I document the arrangement of a lesser-know work for the modern tuned bass using the manuscript as the source material. Finally, by performing a variety of eighteenth-century bass works, I bring this music to the public's attention. The research for this dissertation has been presented in two forms. The recitals present both solo and chamber works from eighteenth-century Vienna. The repertoire for the three recitals was chosen so that each recital addresses one of the three purposes mentioned above. The research paper presents performance practices of the eighteenth century, challenges the modern double bassist faces when playing this literature, as well as a look into how to arrange one of these works for the modern tuned double bass. The three recitals were performed on the campus of the University of Maryland in the Leah M. Smith Hall, Gildenhorn Recital Hall and the Ulrich Recital Hall, respectively. Recordings of all three recitals can be found in the Digital Repository at the University of Maryland (DRUM).

Relatório de estágio de qualificação profissional

Relatório EPE - Relatório de estágio em Educação Pré-Escolar: O presente Relatório de Estágio de Qualificação Profissional situa-se no contexto de Educação Pré-Escolar, tendo como propósito revelar o que foi sendo realizado no Centro Social da Paróquia Nossa Senhora da Ajuda ao longo de quatro meses em contexto de creche. A prática educativa sustentou-se num quadro teórico-concetual de referência, com vista à construção de saberes para a Educação de Infância, pelo compromisso e responsabilização progressiva da ação docente, tendo sido encarado como um momento de singular importância. O contexto de formação assumiu-se, portanto, como um lugar privilegiado de articulação entre teoria e prática, onde o processo de ensino e aprendizagem ficou pautado por intencionalidades educativas com vista ao desenvolvimento integral de cada criança, bem como para a construção de saberes e competências profissionais. No âmbito da investigação-ação e associada à observação, à planificação, à avaliação e à ação propriamente dita, esteve sempre presente a comunicação e a articulação, pois são estas etapas interligadas que revelam a intencionalidade do processo educativo que carateriza a intervenção profissional do educador. A reflexão evidenciou-se também fulcral, pois só mediante uma reflexão na ação e sobre a ação é possível uma introspeção pessoal, despoletando uma compreensão mais sustentada da ação, facilitando a tomada de decisões conscientes. Salienta-se, ainda, a importância de uma formação profissional ao longo da vida, de modo a potenciar o desenvolvimento de uma atitude perante a Educação cada vez mais crítica, indagadora e reflexiva, em prol do desenvolvimento de cada criança.

Scheduling of track inspection and maintenance activities in railroad networks

The U.S. railroad companies spend billions of dollars every year on railroad track maintenance in order to ensure safety and operational efficiency of their railroad networks. Besides maintenance costs, other costs such as train accident costs, train and shipment delay costs and rolling stock maintenance costs are also closely related to track maintenance activities. Optimizing the track maintenance process on the extensive railroad networks is a very complex problem with major cost implications. Currently, the decision making process for track maintenance planning is largely manual and primarily relies on the knowledge and judgment of experts. There is considerable potential to improve the process by using operations research techniques to develop solutions to the optimization problems on track maintenance. In this dissertation study, we propose a range of mathematical models and solution algorithms for three network-level scheduling problems on track maintenance: track inspection scheduling problem (TISP), production team scheduling problem (PTSP) and job-to-project clustering problem (JTPCP). TISP involves a set of inspection teams which travel over the railroad network to identify track defects. It is a large-scale routing and scheduling problem where thousands of tasks are to be scheduled subject to many difficult side constraints such as periodicity constraints and discrete working time constraints. A vehicle routing problem formulation was proposed for TISP, and a customized heuristic algorithm was developed to solve the model. The algorithm iteratively applies a constructive heuristic and a local search algorithm in an incremental scheduling horizon framework. The proposed model and algorithm have been adopted by a Class I railroad in its decision making process. Real-world case studies show the proposed approach outperforms the manual approach in short-term scheduling and can be used to conduct long-term what-if analyses to yield managerial insights. PTSP schedules capital track maintenance projects, which are the largest track maintenance activities and account for the majority of railroad capital spending. A time-space network model was proposed to formulate PTSP. More than ten types of side constraints were considered in the model, including very complex constraints such as mutual exclusion constraints and consecution constraints. A multiple neighborhood search algorithm, including a decomposition and restriction search and a block-interchange search, was developed to solve the model. Various performance enhancement techniques, such as data reduction, augmented cost function and subproblem prioritization, were developed to improve the algorithm. The proposed approach has been adopted by a Class I railroad for two years. Our numerical results show the model solutions are able to satisfy all hard constraints and most soft constraints. Compared with the existing manual procedure, the proposed approach is able to bring significant cost savings and operational efficiency improvement. JTPCP is an intermediate problem between TISP and PTSP. It focuses on clustering thousands of capital track maintenance jobs (based on the defects identified in track inspection) into projects so that the projects can be scheduled in PTSP. A vehicle routing problem based model and a multiple-step heuristic algorithm were developed to solve this problem. Various side constraints such as mutual exclusion constraints and rounding constraints were considered. The proposed approach has been applied in practice and has shown good performance in both solution quality and efficiency.

A dramaturgia do sonho : um estudo sobre as relações entre a dança e o circo contemporâneos

O ponto de partida desta investigação foi a encenação do espetáculo de cariz circense Cadernos Suspensos. A encenação desta peça despertou questões sobre o processo criativo e o papel da dança e da dramaturgia no circo contemporâneo. Considerando as diferenças constatadas entre os ‘corpos’ do circo e da dança, são identificados modos de ação desses mesmos corpos e introduzida a questão do surgimento de um novo corpo resultante dessas duas experiências e vivências performativas. Neste estudo é analisada a diluição de fronteiras entre o circo e a dança e considerado que o resultado desse encontro, com a ajuda da dramaturgia, poderá ter contribuído para o surgimento de um novo discurso circense. O aumento das produções artísticas onde circo, dança e teatro coexistem induz a crer que há um crescente interesse nessas formas artísticas. Este estudo pretende pois contribuir para uma reflexão sobre as apropriações recíprocas do circo e da dança. Os argumentos explanados congregam a experiência e vivência pessoal nos campos das artes circenses e da dança, assim como o contributo teórico e experiencial de autores e artistas como Jacob, Guy, Lefèvre e Sizorn, Fourmaux, Nadj, Decouflé, Platel e Zimmermann & de Perrot. Discute-se a possibilidade de uma certa dança contemporânea ter-se apropriado do circo para resgatar um espaço perdido de sonho assim como uma potencialização física do corpo.
