A normative method to analyse workarounds in a healthcare environment: motivations, consequences, and constraints

Healthcare information systems have the potential to enhance productivity, lower costs, and reduce medication errors by automating business processes. However, various issues such as system complexity and system abilities in a relation to user requirements as well as rapid changes in business needs have an impact on the use of these systems. In many cases failure of a system to meet business process needs has pushed users to develop alternative work processes (workarounds) to fill this gap. Some research has been undertaken on why users are motivated to perform and create workarounds. However, very little research has assessed the consequences on patient safety. Moreover, the impact of performing these workarounds on the organisation and how to quantify risks and benefits is not well analysed. Generally, there is a lack of rigorous understanding and qualitative and quantitative studies on healthcare IS workarounds and their outcomes. This project applies A Normative Approach for Modelling Workarounds to develop A Model of Motivation, Constraints, and Consequences. It aims to understand the phenomenon in-depth and provide guidelines to organisations on how to deal with workarounds. Finally the method is demonstrated on a case study example and its relative merits discussed.

Linking urban water balance and energy balance models to analyse urban design options

Using a water balance modelling framework, this paper analyses the effects of urban design on the water balance, with a focus on evapotranspiration and storm water. First, two quite different urban water balance models are compared: Aquacycle which has been calibrated for a suburban catchment in Canberra, Australia, and the single-source urban evapotranspiration-interception scheme (SUES), an energy-based approach with a biophysically advanced representation of interception and evapotranspiration. A fair agreement between the two modelled estimates of evapotranspiration was significantly improved by allowing the vegetation cover (leaf area index, LAI) to vary seasonally, demonstrating the potential of SUES to quantify the links between water sensitive urban design and microclimates and the advantage of comparing the two modelling approaches. The comparison also revealed where improvements to SUES are needed, chiefly through improved estimates of vegetation cover dynamics as input to SUES, and more rigorous parameterization of the surface resistance equations using local-scale suburban flux measurements. Second, Aquacycle is used to identify the impact of an array of water sensitive urban design features on the water balance terms. This analysis confirms the potential to passively control urban microclimate by suburban design features that maximize evapotranspiration, such as vegetated roofs. The subsequent effects on daily maximum air temperatures are estimated using an atmospheric boundary layer budget. Potential energy savings of about 2% in summer cooling are estimated from this analysis. This is a clear ‘return on investment’ of using water to maintain urban greenspace, whether as parks distributed throughout an urban area or individual gardens or vegetated roofs.

Diagnostic tool to analyse colour-magnitude diagrams of poorly populated stellar concentrations

The dynamical processes that lead to open cluster disruption cause its mass to decrease. To investigate such processes from the observational point of view, it is important to identify open cluster remnants (OCRs), which are intrinsically poorly populated. Due to their nature, distinguishing them from field star fluctuations is still an unresolved issue. In this work, we developed a statistical diagnostic tool to distinguish poorly populated star concentrations from background field fluctuations. We use 2MASS photometry to explore one of the conditions required for a stellar group to be a physical group: to produce distinct sequences in a colour-magnitude diagram (CMD). We use automated tools to (i) derive the limiting radius; (ii) decontaminate the field and assign membership probabilities; (iii) fit isochrones; and (iv) compare object and field CMDs, considering the isochrone solution, in order to verify the similarity. If the object cannot be statistically considered as a field fluctuation, we derive its probable age, distance modulus, reddening and uncertainties in a self-consistent way. As a test, we apply the tool to open clusters and comparison fields. Finally, we study the OCR candidates DoDz 6, NGC 272, ESO 435 SC48 and ESO 325 SC15. The tool is optimized to treat these low-statistic objects and to separate the best OCR candidates for studies on kinematics and chemical composition. The study of the possible OCRs will certainly provide a deep understanding of OCR properties and constraints for theoretical models, including insights into the evolution of open clusters and dissolution rates.

Using stochastic volatility models to analyse weekly ozone averages in Mexico City

In this paper we make use of some stochastic volatility models to analyse the behaviour of a weekly ozone average measurements series. The models considered here have been used previously in problems related to financial time series. Two models are considered and their parameters are estimated using a Bayesian approach based on Markov chain Monte Carlo (MCMC) methods. Both models are applied to the data provided by the monitoring network of the Metropolitan Area of Mexico City. The selection of the best model for that specific data set is performed using the Deviance Information Criterion and the Conditional Predictive Ordinate method.

Volsurf Descriptors to Analyse Anti-HCV and Cytotoxic Activities of Sesquiterpene Lactones from Asteraceae Family

Various significant anti-HCV and cytotoxic sesquiterpene lactones (SLs) have been characterized. In this work, the chemometric tool Principal Component Analysis (PCA) was applied to two sets of SLs and the variance of the biological activity was explored. The first principal component accounts for as much of the variability in the data as possible, and each succeeding component accounts for as much of the remaining variability as possible. The calculations were performed using VolSurf program. For anti-HCV activity, PC1 (First Principal Component) explained 30.3% and PC2 (Second Principal Component) explained 26.5% of matrix total variance, while for cytotoxic activity, PC1 explained 30.9% and PC2 explained 15.6% of the total variance. The formalism employed generated good exploratory and predictive results and we identified some structural features, for both sets, important to the suitable biological activity and pharmacokinetic profile.

Wirklichkeit und Fiktion in Günter Grass Im Krebsgang : Eine erzähltheoretische Analyse

Die Novelle, Im Krebsgang, von Günter Grass ist eine Mischung aus Zeitgeschichte, persönlicher Biografie des Autors und lebhafter Fantasie. Diese Komponenten auseinanderzuhalten könnte die Verständigung der Novelle verbessern. Nach den Annahmen, dass der engste Personenkreis um die Familie Pokriefke Fiktion ist, und die Geschichten um den U-Boot-Kommandanten Marinesko, den Medizinstudenten Frankfurter, den Nationalsozialisten Gustloff und das KdF-Schiff Wilhelm Gustloff faktual sind, wurden sechs Textabschnitte ausgewählt. Durch eine literaturwissenschaftliche Analyse dieser Textabschnitte wurden sechs Punkte gefunden, die die Trennlinie zwischen den fiktionalen und faktualen Textabschnitten identifizieren. Gefunden wurde, dass in den faktualen Texten der Erzähler immer auktorial, aus großer Distanz berichtet, und immer von der Fokalisierung getrennt ist. In den fiktionalen Texten aber liegt immer die Fokalisierung beim Erzähler, der stets szenisch erzählt.

Tu dis et je murmure! : Une analyse des verbes de parole dans la littérature suédoise pour enfants et leurs traductions en français

This study presents a description of the role of verbs in introducing the direct dialogue in literacy and of the way they are translated from Swedish to French in children’s literature. In order to adapt the text to the target language, these verbs sometimes change and lose their impact on the tone and character of the dialogue. This can be problematic in texts aimed for children where readability depends on a child’s language capacity. Another aim of this study is to expose des difficulties encountered in the transfer of values and emotional effects when translating children’s literature from source language to target languageOur conclusion is that the Swedish children’s literature translated to French is often subject to modifications rather than translation of verbs that introduce direct dialogue. Consequently, dialogue meaning and character personalities are modified within the text translation. In our analysis of four Swedish children’s books and their translation to French we have seen that these adaptations are not made for adapting to the intended reader’s capacities in the target language or to the literacy of the source text but rather to adapt to certain linguistic norms relative to the style of French language.

Die bibelübersetzung Martin Luthers : eine soziolinguistische analyse der absicht, der methode und der auswirkung

Brundin (2004, S. 63) sagt, dass sich die Reformation „um einen Kampf handelte, der Auswirkungen auf die ganze gesellschaftliche Struktur hatte.“ Das Ziel dieser Arbeit ist die Absichten hinter, die linguistischen Methoden und die sozialen Auswirkungen der Bibelübersetzung Luthers festzustellen, und dadurch die Aussage Brundins zu bestätigen bzw. widerlegen. Es wurde gefunden, dass Martin Luther die Bibelübersetzung und die Reformation in enger Zusammenarbeit mit seinen Kollegen an der Leucorea Universität und unter Führung des sächsischen Kurfürsten, Friedrich III., durchgeführt hat. Dabei haben die verwendeten linguistischen Methoden eine Schlüsselrolle gespielt, und viele heute bekannten wissenschaftlichen Theorien sind praktisch umgesetzt worden. Dazu gehören die Sapir-Whorf-Hypothese, die Defizit- bzw. die Differenzhypothese und die Diskurstheorie. Die Reformation hat eine gewaltige Machtverschiebung zur Folge, wo der Klerus dem Adel viele Rechte abgeben müsste, und die neu erzeugte Sprache der Lutherbibel hat zu einer deutschen Einheitssprache und die Erstehung eines deutschen Nationalstaates geführt. Als Schlussergebnis kann die Aussage Brundins klar bestätigt werden.

Le Réalisme dans le roman policier : Une Analyse du réalisme des décors, des personnages et de l'enquête dans deux romans policiers

Ce mémoire a pour but de comparer deux romans policiers contemporains et ayant eu un grand succès, l’un écrit par Henning Mankell dont la traduction française a paru sous le titre Les Morts de la Saint-Jean et le second est Pars vite et reviens tard de Fred Vargas. L’objectif de la candidate est d’essayer de trouver les éléments réalistes dans le décor, les personnages et l’enquête. Pour ce qui est du premier paramètre, la candidate montre que Mankell n’essaie jamais de cacher la vérité derrière une surface idéale ; il en va de même pour Vargas qui accentue les points de vue divergents des Français sur la réalité de leur pays. En ce qui a trait aux personnages, on distingue dans le portrait qu’en fait Mankell un combat compliqué et non manichéen, proche de la réalité psychologique; idem pour ceux de Vargas, mais le réalisme est quelque peu atténué par un recours au mystère. Enfin, l’enquête menée par Wallander aboutit un peu par hasard grâce à son intuition alors qu’Adamsberg résout l’énigme grâce à sa faculté de voir, de s’imaginer et d’aller au-delà de la capacité des autres. La conclusion générale du mémoire est que ces deux œuvres sont tout à fait réalistes, mais à un degré un peu différent. Le roman de Mankell l’est sans doute davantage dans la mesure où le recours au mystère est écarté et que l’enquête est menée de façon logique alors que le roman de Vargas, tout en suivant les règles de la logique, a tendance à faire appel au merveilleux. En tout état de cause, il s’agit de deux œuvres réalistes comportant un côté romantique plus ou moins bien exprimé.

Le poète errant à Port-au-Prince : Une lecture de _Parias_ de Magloire Saint-Aude

Cet article offre une analyse de la figure du flâneur dans Parias: documentaire de l’écrivain haïtien Magloire-Saint-Aude (1912-1971). Étudiant la façon dont il se réapproprie de ce trope surréaliste dans un cadre port-au-princien, le but est de montrer que l’auteur essaie de repenser le sujet haïtien. L’article démontre que Magloire-Saint-Aude se sert d’un chronotope urbain double, d’abord les rues pauvres où les personnages déambulent sans but fixe et ensuite les salons bourgeois où naît le désir. Son flâneur haïtien subit un processus complexe de subjectivation qui s’articule dans la tension de ces deux chronotopes urbains. Même si le héros saint-audien essaye de se libérer par le biais de l’amour pour une Française il est à jamais attaché à l’espace exigu de Port-au-Prince. Cela vient rompre avec une tradition d’affirmation héroïque du sujet (masculin) haïtien. ”Exilé de l’intérieur,” Malgoire-Saint-Aude explore un sujet insaisissable qui garde ouverte sa part à l’altérité.
