O impacto do ativo intangível medido pelo efeito da inovação organizacional em instituição pública multipropósito: o caso do Instituto Nacional de Infectologia Evandro Chagas - INI da Fiocruz

Esta dissertação foi desenvolvida no Instituto Nacional de Infectologia Evandro Chagas (INI) da Fundação Oswaldo Cruz (Fiocruz), uma organização pública multipropósito de saúde com atividades de pesquisa, assistência e ensino, que adotou a estratégia de inovar a sua estrutura organizacional, com vistas a garantir a qualidade dos serviços prestados à população, bem como reforçar a orientação empreendedora das suas ações integradas. Sob o ponto de vista da pesquisa em Ciências Contábeis, a reestruturação do INI constitui um exemplo potencial da acumulação de ativo intangível pela organização e este foi o fato gerador do problema da pesquisa: a aplicação do método DEA para avaliar a melhoria da eficiência dos oito laboratórios de pesquisa multipropósito do INI, está associada ao referencial teórico que justifica a inovação organizacional implantada no Instituto após proposta nos Congressos Internos da Fiocruz? O objetivo geral foi analisar os resultados dos escore-sínteses do Data Envelopment Analysis (DEA), como medida dos ativos intangíveis, associando-os aos efeitos provenientes da implantação de mudanças organizacionais estratégicas, caracterizadas como inovações organizacionais ocorridas nos oito laboratórios de pesquisa clínica multipropósitos, isto é, que contemplam ensino, pesquisa e assistência, no INI da Fiocruz. O método consistiu de quatro etapas. Na primeira, foi realizada a análise da literatura sobre ativos intangíveis; inovação organizacional; estruturas da organização e modelo de análise de eficiência em organizações. Na segunda, foi realizada a coleta dos indicadores qualitativos referentes a mudança da estrutura organizacional de oito laboratórios do INI por meio de análise documental dos Congressos Internos da Fiocruz e uma pesquisa de opinião dos representantes dos laboratórios; quantitativamente, foram levantados dados para calcular o indicador de eficiência de cada um dos laboratórios. Na terceira etapa foi realizada a análise dos dados coletados, do período de 2006-2012, utilizando os indicadores calculados para associar a eficiência do conjunto destas atividades antes e depois da inovação organizacional associada à adoção de uma estrutura inovadora na reestruturação. Finalmente, a quarta etapa apresentou os resultados e as respectivas considerações sobre a pesquisa. Como contribuição, apresenta-se uma associação entre a inovação organizacional, decorrente da reestruturação dos oito laboratórios de pesquisa clínica e os resultados do método empírico que utiliza o DEA.

Object files can be purely episodic.

Our ability to track an object as the same persisting entity over time and motion may primarily rely on spatiotemporal representations which encode some, but not all, of an object's features. Previous researchers using the 'object reviewing' paradigm have demonstrated that such representations can store featural information of well-learned stimuli such as letters and words at a highly abstract level. However, it is unknown whether these representations can also store purely episodic information (i.e. information obtained from a single, novel encounter) that does not correspond to pre-existing type-representations in long-term memory. Here, in an object-reviewing experiment with novel face images as stimuli, observers still produced reliable object-specific preview benefits in dynamic displays: a preview of a novel face on a specific object speeded the recognition of that particular face at a later point when it appeared again on the same object compared to when it reappeared on a different object (beyond display-wide priming), even when all objects moved to new positions in the intervening delay. This case study demonstrates that the mid-level visual representations which keep track of persisting identity over time--e.g. 'object files', in one popular framework can store not only abstract types from long-term memory, but also specific tokens from online visual experience.

Accessing Social Work Case Files for Research Purposes: Some Issues and Problems

The use of social work case files as an important research resource is being threatened by the increasing regulation of both the research process and access to personal identifiable information. While these developments can be seen as a reaction to specific incidents of inappropriate research and the misuse of personal information, it is argued that the pendulum has swung too far the other way, and in seeking to protect the rights of vulnerable individuals, the lives of these same individuals may go unstudied with the consequence that they receive less appropriate services. Drawing upon the current research of the authors, this article explores the difficulties encountered in gaining access to social work case files for research purposes without the explicit consent of service users and highlights the uncertainty surrounding this issue. Suggestions are made for improvements in the situation.

HBrowse: a GRACE tool for browsing R-matrix H-files

An H-file is used to convey information from the inner-region to the outer-region in R-matrix computations. HBrowse is a workstation tool for displaying a graphical abstraction of a local or remote R-matrix H-file. While it is published as a stand-alone tool for post-processing the output from R-matrix inner-region computations it also forms part of the Graphical R-matrix Atomic Collision Environment (GRACE), HBrowse is written in C and OSF/Motif for the UNIX operating system.

History of Child Welfare and Protection Social Work in Northern Ireland: Finding Continuity amongst Discontinuity in Case Files from 1950-1968

This article reports on research carried out on 200 child welfare files from the largest welfare authority in Northern Ireland from 1950-1968. The literature review provides a commentary on some of the major debates surrounding child welfare and protection social work from the perspective of its historical development. The report of the research which follows offers an insight into one core, and less well-known period of child welfare history in Northern Ireland between the two Children and Young Persons Acts (1950 & 1968). Using a method of discourse analysis influenced by Michel Foucault, a detailed description of the nature of practice is offered. This paper is offered as a work in progress, with further work being planned for dissemination of more detailed analysis of the method and outcomes. The research seeks to ask a few core questions based on problems identified in the present with our current understandings of child welfare and protection histories. While recognising the limitations of this study and the need for broader analysis of the wider context surrounding child welfare practice at the moment, it is argued that some salient conclusions can be drawn about continuity and discontinuity in practice which are of interest to practitioners and students of child welfare social work.

Implementation of phantom-less IMRT delivery verification using Varian DynaLog files and R/V output

This study aims to evaluate the use of Varian radiotherapy dynamic treatment log (DynaLog) files to verify IMRT plan delivery as part of a routine quality assurance procedure. Delivery accuracy in terms of machine performance was quantified by multileaf collimator (MLC) position errors and fluence delivery accuracy for patients receiving intensity modulated radiation therapy (IMRT) treatment. The relationship between machine performance and plan complexity, quantified by the modulation complexity score (MCS) was also investigated. Actual MLC positions and delivered fraction of monitor units (MU), recorded every 50 ms during IMRT delivery, were extracted from the DynaLog files. The planned MLC positions and fractional MU were taken from the record and verify system MLC control file. Planned and delivered beam data were compared to determine leaf position errors with and without the overshoot effect. Analysis was also performed on planned and actual fluence maps reconstructed from the MLC control file and delivered treatment log files respectively. This analysis was performed for all treatment fractions for 5 prostate, 5 prostate and pelvic node (PPN) and 5 head and neck (H&N) IMRT plans, totalling 82 IMRT fields in ∼5500 DynaLog files. The root mean square (RMS) leaf position errors without the overshoot effect were 0.09, 0.26, 0.19 mm for the prostate, PPN and H&N plans respectively, which increased to 0.30, 0.39 and 0.30 mm when the overshoot effect was considered. Average errors were not affected by the overshoot effect and were 0.05, 0.13 and 0.17 mm for prostate, PPN and H&N plans respectively. The percentage of pixels passing fluence map gamma analysis at 3%/3 mm was 99.94 ± 0.25%, which reduced to 91.62 ± 11.39% at 1%/1 mm criterion. Leaf position errors, but not gamma passing rate, were directly related to plan complexity as determined by the MCS. Site specific confidence intervals for average leaf position errors were set at -0.03-0.12 mm for prostate and -0.02-0.28 mm for more complex PPN and H&N plans. For all treatment sites confidence intervals for RMS errors with the overshoot was set at 0-0.50 mm and for the percentage of pixels passing a gamma analysis at 1%/1 mm a confidence interval of 68.83% was set also for all treatment sites. This work demonstrates the successful implementation of treatment log files to validate IMRT deliveries and how dynamic log files can diagnose delivery errors not possible with phantom based QC. Machine performance was found to be directly related to plan complexity but this is not the dominant determinant of delivery accuracy.

Monitoring daily MLC positional errors using trajectory log files and EPID measurements for IMRT and VMAT deliveries

This work investigated the differences between multileaf collimator (MLC) positioning accuracy determined using either log files or electronic portal imaging devices (EPID) and then assessed the possibility of reducing patient specific quality control (QC) via phantom-less methodologies. In-house software was developed, and validated, to track MLC positional accuracy with the rotational and static gantry picket fence tests using an integrated electronic portal image. This software was used to monitor MLC daily performance over a 1 year period for two Varian TrueBeam linear accelerators, with the results directly compared with MLC positions determined using leaf trajectory log files. This software was validated by introducing known shifts and collimator errors. Skewness of the MLCs was found to be 0.03 ± 0.06° (mean ±1 standard deviation (SD)) and was dependent on whether the collimator was rotated manually or automatically. Trajectory log files, analysed using in-house software, showed average MLC positioning errors with a magnitude of 0.004 ± 0.003 mm (rotational) and 0.004 ± 0.011 mm (static) across two TrueBeam units over 1 year (mean ±1 SD). These ranges, as indicated by the SD, were lower than the related average MLC positioning errors of 0.000 ± 0.025 mm (rotational) and 0.000 ± 0.039 mm (static) that were obtained using the in-house EPID based software. The range of EPID measured MLC positional errors was larger due to the inherent uncertainties of the procedure. Over the duration of the study, multiple MLC positional errors were detected using the EPID based software but these same errors were not detected using the trajectory log files. This work shows the importance of increasing linac specific QC when phantom-less methodologies, such as the use of log files, are used to reduce patient specific QC. Tolerances of 0.25 mm have been created for the MLC positional errors using the EPID-based automated picket fence test. The software allows diagnosis of any specific leaf that needs repair and gives an indication as to the course of action that is required.

Comparison Method for Differentiation of IEC 61850 based Substation Configuration Files

The increased construction and reconstruction of smart substations has exposed a problem with version management of substation configuration description language (SCL) files due to frequent changes. This paper proposes a comparative approach for differentiation of smart substation SCL configuration files. A comparison model for SCL configuration files is built in this method, which is based on the SCL structure and abstract model defined by IEC 61850. The proposed approach adopts the algorithms of depth-first traversal, sorting, and cross comparison in order to rapidly identify differences of changed SCL configuration files. This approach can also be utilized to detect malicious tampering or illegal manipulation tailoring for SCL files. SCL comparison software is developed using the Qt platform to validate the feasibility and effectiveness of the proposed approach.
