Texto completoWith the rise of global warming issues due to the increase of the greenhouse gas emission and more generally with growing importance granted to sustainable development, process system engineering (PSE) has turned to think more and more environmentally. Indeed, the chemical engineer has now taken into account not only the economic criteria of the process, but also its environmental and social performances. On the other hand LCA is a method used to evaluate the potential impacts on the environment of a product, process, or activity throughout its life cycle. The research here focused on coupling of PSE domain with the environmental analysis of agricultural and chemical activities and abatement strategies for agro-processes with the help of computer aided tools and models. Among many approaches, the coupling of PSE and LCA is investigated here because it is viewed as a good instrument to evaluate the environmental performance of different unitary processes and whole process. The coupling can be of different nature depending on the focus of the study. The main objective is to define an innovative LCA based on approach for a deep integration of product, process and system perspectives. We selected a PSE embedded LCA and proposed a framework that would lead to an improved eco-analysis, eco-design and eco-decision of business processes and resulted products for researchers and engineers. In the first place we evaluate biodiesel for environmental analysis with the help of field data, background data and impact methodologies. Through this environmental evaluation, we identify the hotspot in the whole production system. To complement the experimental data this hotspot (i.e. transesterification) is selected for further modeling and simulation. For results validation, we also implement LCA in a dedicated tool (SimaPro) and simulation in a PSE simulation tool (Prosim Plus). Finally we develop a tool (SimLCA) dedicated to the LCA by using PSE tools and methodologies. This development of SimLCA framework can serve as a step forward for determination of sustainability and eco-efficient designing

Texto completoIt is evident that many students admitted to higher education in South Africa are ill-prepared for tertiary study. The predominantly behaviorist school system encourages learner dependency and superficial understanding and fails to encourage reflection and self-direction. Changing times and a more diverse student population have heightened the need for a broader range of teaching and learning approaches at tertiary level. As a result, many departments, faculties and institutes such as SciMathUS have explored the merits of problem-based learning (PBL) which supports students as self-directed, independent learners. Problem-based learning is a different philosophical approach to the whole notion of teaching and learning where problems drive the learning and is one of the best examples of a constructivist learning environment. Thus far, problem-based learning has mainly been implemented in long-term medical curricula, so research findings focus mainly on the development of PBL for longer programmes. The purpose of this study is to evaluate whether introducing a Hybrid PBL approach in a shorter one-year foundation programme can create conditions for learners to develop and sustain self-directed learning skills and gain more control of the learning process. This interpretive-constructivist study may be broadly termed evaluation research. A mixedmethod approach that involved collecting and analyzing both qualitative and quantitative data was chosen. Evaluation findings indicate that introducing students to a Hybrid PBL approach does promote more meaningful learning patterns, typified by processing the subject matter critically and self-regulating learning processes. However the sustainability of the meaningdirected learning activities is questionable if student beliefs do not support the activities employed. Findings also reveal that the Hybrid PBL approach contributes to overall programme improvement by promoting understanding in mathematics and science and improved staff relationships and subject knowledge. PBL helps to establish a learner-centered learning environment that emphasizes relations in mathematics and science, promotes deep approaches to learning which may lead to higher levels of achievement and success in Higher Education.

Texto completoIn the European context which aims at reducing risk and uses of pesticides, the development of tools to evaluate environmental impacts is a major focus. This thesis uses ecotoxicological and ecological approaches, from tissue level to population level. The model species is a generalist predator, the earwig, and the study site is apple orchards in Southeastern France. Pesticides expositions were tested both in laboratory or real conditions (in orchards). Lab studies allowed us to characterize and investigate the tissular distribution of B-esterases (AChE and CbE) of Forficula auricularia and to study its predatory behavior on the aphid Dysaphis plantaginea after exposure. CbE were more sensitive than AChE and males B-esterases were more sensitive than females ones to organophosphorus pesticides. The overall results allowed us to validate the use of B-esterases as biochemical biomarkers on F. auricularia. The predation behavior of F. auricularia was impacted by some insecticides with males more sensitive than females. The behavior results were supported by inhibition of biochemical biomarkers (B-esterases) validating predation behavior as a new biomarker. Taking into account the individual level, the reproduction and development of first larval stages were carried out thanks to a breeding set up with earwigs trapped in orchards conducted under different pest management (organic, integrated and conventional management). Eggs number by clutch was reduced and clutch date was delayed for earwigs trapped in orchards conducted under conventional agriculture. To assess the impact of pesticides on population level, the abundance and diversity of earwig (F. auricularia and F. pubescens) were carried out in different orchard management considering small-scale landscape parameters. Pesticide use had clearly much higher effects on earwig abundances and diversity than landscape characteristics. F. pubescens was more sensitive than F. auricularia, with the same sensitivity difference between sex on both species (males more sensitive) making earwigs a relevant bioindicator species of pesticides use in apple orchards. This study enhances the need of complementary biomarkers able to highlight physiological and behavioral modifications which influence natural enemy populations and the natural regulation of pests

Texto completoStäder och stadsdelar står för en stor del av totala energikonsumtionen i Sverige. Bostads- och servicesektor stod för ungefär 40% av totala energikonsumtionen under 2018. Den ökande urbaniseringen lägger också mer vikt vid energiproduktion, distribution och konsumtionen i dessa områden. Ett alternativ för planering av energisystem i urbana områden är att ha integrerade energisystem där synergier mellan olika teknologier och energibärare kan utnyttjas. Den typen av system skulle kunna öka flexibiliteten i energisystemet och därför förenkla integrering av oförutsägbara förnybara energikällor. Syftet med denna studie var att föreslå verktyg för planering av energisystem i stadsdelar. Detta gjordes genom en litteraturstudie angående utformningen av olika energisystem samt identifiera hinder och möjligheter för att integrera olika produktions- och distributions teknologier. Fokus låg på systemen för värme, kyla och elektricitet. Det föreslagna verktygen är tre Excel baserade moduler. Den första modulen är en qualitative modell som presenterar de studerade teknologier och deras kopplingar. Den innehåller också synergier mellan de olika energibärarna och konsumtions- och produktionssektorn. Den andra modulen är en qualitative modell, men relaterad till marknad mekanismer, juridiska, organisatoriska och institutionella aspekter. Den tredje modulen är en tabell som beskriver hinder och möjligheter för några av teknologierna. Utöver det de relevanta aktörerna identifierades. För värme-, kyla- och elektricitet marknaden är de fjärrvärmeföretagen, fastighetsägare, samfälligheter, kommuner, fjärrkyla företagen, solcells ägare. De föreslagna verktyget kan användas för planering av energisystem i ett första skede när teknologier ska väljas. En fallstudie genomfördes för att visa hur det föreslagna verktyget kan användas. Fallstudien en stadsdel som planeras i Stockholm, Sverige. För att genomföra en analys behövdes en modell för ett hypotetiskt värmesystem. Två modeller utvecklades för värmesystemet genom att använda modelleringsmiljön OpenModelica. Det huvudsakliga målet med fallstudien var att jämföra den teknoekonomiska- och miljöinriktade prestandan för olika scenarierna. Tre olika scenarier övervägdes för att täcka totala värmebehovet i stadsdelen. I det första scenariot täcks det totala värmebehovet endast av lokala värmepumpar. I andra scenariot täcks värmebehovet för uppvärmning av värmepump(ar) kopplade till en värmelagrings komponent (ackumulatortank). En elpanna användes för reserveffekt. I tredje scenariot är elpannan ersatt av fjärrvärme. En känslighetsanalys var utförd för olika antal värmepumpar kopplade till olika storlekar av värmelagrings-komponenten i de två sista scenarierna. De ekonomiska och miljörelaterade resultatet i den här studien är starkt beroende av antaganden gällande priser och utsläppsfaktorer. Resultatet indikerar att det tredje scenariot har de lägsta CO2 utsläppen. Ökad värmelagringsstorlek bidrar till att värmepumpen förbrukar mer elektricitet och därför ökar de relaterade utsläppen. Däremot beror de totala utsläppen i systemet på vilken reservkraft som används. För dessa resultat användes utsläppsfaktorn för svensk elmix samt utsläppsfaktorn från ett fjärrvärme företag i Stockholm. Den billigaste alternativet gällande årlig driftsenergikostnad är det första scenariot med endast värmepumpar. Däremot, bland de scenarion som innehåller värmelagring, har det andra scenariot med tre värmepumpar och 100m3 stor värmelagringsenhet den lägsta kostnaden. Detta system är endast 0.6% dyrare än det första scenariot. För energipriser har timvärden från Nordpol antagits för elektricitet och för värme har normalprislistan från ett fjärrvärmebolag i Stockholm antagits. Angående den tekniska systemprestandan, indikerar resultatet att bidraget från värmelagringsenheten som den är modellerad i den här fallstudien inte är signifikant på årsbasis. Det observeras emellertid att en större värmelagringsenhet täcker en större andel av effektbehovet under de timmar som enheten används.

Texto completoBackground: Practice knowledge exists as a complex relationship between questions and answers in a context of meaning that is often intuitive and hidden from the novice practitioner. Physiotherapy education, which aims to develop patterns of thinking, reflection and reasoning as part of practice knowledge, is often based on didactic teaching methods that emphasise the learning of facts without highlighting the relationships between them. In order to improve health outcomes for patients, clinical educators must 
consider redesigning the curriculum to take into account the changing and complex nature of physiotherapy education. There is some evidence that a blended approach to 
teaching and learning may facilitate the development of graduates who are more capable of reflection, reasoning and critical thinking, and who can adapt and respond to the 
complex clinical environment. The purpose of this study was to develop principles that could be used to guide the design of blended learning environments that aim to develop 
capability in undergraduate physiotherapy students. Method: The study took place in a university physiotherapy department in the Western Cape in South Africa, among 
undergraduate students. Design research was used as a framework to guide the study, and included a range of research methods as part of that process. The problem was 
identified using a systematic review of the literature and a survey of students. The design of the blended intervention that aimed to address the problem was informed by a 
narrative review of theoretical frameworks, two pilot studies that evaluated different aspects of blended learning, and a Delphi study. This process led to the development of a set 
of design principles which were used to inform the blended intervention, which was implemented and evaluated during 2012. Results: The final results showed that students had undergone a transformation in how they thought about the process and practice of learning as part of physiotherapy education, demonstrating critical approaches towards 
knowledge, the profession and authority. These changes were brought about by changing teaching and learning practices that were informed by the design principles in the 
preliminary phases of the project. These principles emphasised the use of technology to interact, articulate understanding, build relationships, embrace complexity, encourage 
creativity, stimulate reflection, acknowledge emotion, enhance flexibility and immerse students in the learning space. Discussion: While clinical education is a complex undertaking with many challenges, evidence presented in this study demonstrates that the development of clinical reasoning, critical thinking and reflection can be enhanced through the intentional use of technology as part of a blended approach to teaching and learning. The design principles offer clinical educators a framework upon which to construct learning environments where the affordances of technology can be mapped to the principles, which are based on a sound pedagogical foundation. In this way, the use of technology in the learning environment is constructed around principles that are informed by theory. However, clinical educators who are considering the integration of 
innovative strategies in the curriculum should be aware that students may initially be reluctant to engage in self-directed learning activities, and that resistance from colleagues 
may obstruct the process. Conclusion: The development of clinical reasoning, critical thinking and reflection in undergraduate physiotherapy students may be enhanced through 
the intentional use of appropriate technology that aims to fundamentally change teaching and learning practices. Design research offers a practical approach to conducting 
research in clinical education, leading to the development of principles of learning that are based on theory.

Texto completoThe objective of this thesis is twofold: (1) to investigate the synergies arising from the implementation of multi-scale and multi-criteria approaches in the evaluation of rural development policies (RDP); (2) to explore the impacts and trade-offs of RDP in two selected case studies located in Italy and China. The thesis argues that multi-criteria and multi-scale approaches can be combined to provide a useful framework with which to structure an integrated analysis of RDP in order to assess their effectiveness in achieving sustainability goals across scales. The analysis is performed by selecting and evaluating multidimensional criteria, which represent the main goals of development policies in the areas of study. Moreover, multi-scale analysis is performed to define boundary conditions and trade-offs for future local development. The use of the two methodologies appears to be very significant to capture both the multidimensional and multi-scale aspects of the Rural Development Policies analysed and to generate several sets of “view-dependent” representations of rural systems that are useful for trade-off assessments.

Texto completoSandstone and shale samples were selected within the systems tracts for laboratory analyses. The sidewall and core samples were subjected to petrographic thin section analysis, mineralogical analyses which include x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and stable carbon and oxygen isotopes geochemistry to determine the diagenetic alteration at deposition and post deposition in the basin. The shale samples were subjected to Rock-Eval pyrolysis and accelerated solvent extraction (ASE) prior to gas chromatographic (GC) and gas chromatographic-mass spectrometric (GC-MS) analyses of the rock extracts, in order to determine the provenance, type and thermal maturity of organic matter present in sediments of the Orange Basin. The results revealed a complex diagenetic history of sandstones in this basin, which includes compaction, cementation/micritization, dissolution, silicification/overgrowth of quartz, and fracturing. The Eh-pH shows that the cements in the area of the basin under investigation were precipitated under weak acidic and slightly alkaline conditions. The &delta
18O isotope values range from -1.648 to 10.054 %, -1.574 to 13.134 %, and -2.644 to 16.180 % in the LST, TST, and HST, respectively. While &delta
13C isotope values range from -25.667 to -12.44 %, -27.862 to -6.954% and -27.407 to -19.935 % in the LST, TST, and HST, respectively. The plot of &delta
18O versus &delta
13C shows that the sediments were deposited in shallow marine temperate conditions.

Texto completoSystem evolutions have to be managed to ensure system effectiveness and efficiency through its whole lifecycle, particularly when it comes to complex systems that take years of development and dozens of years of usage. System Reconfiguration is key in complex systems management, as it is an enabler of system flexibility and adaptability regarding system evolutions. System reconfiguration ensures operational effectiveness and increases system qualities (e.g., reliability, availability, safety, and usability).This research has been conducted in the context of a large international aerospace, space, ground transportation, defense, and security company. This research aims at supporting system reconfiguration during operations.First, we conducted a descriptive study based on a field study and a literature review to identify the industrial challenges related to system reconfiguration. The main issue lies in the development of reconfiguration support. More specifically, challenges related to data identification and integration were identified.In this thesis, we present the OSysRec ontology, which captures and formalizes the reconfiguration data. The ontology synthesizes the structure, dynamics, and management aspects necessary to support the system reconfiguration process in an overall manner.Furthermore, we present a model-based method (MBSysRec) that integrates system reconfiguration data and bridges both the engineering and the operational phases. MBSysRec is a multidisciplinary method that involves combinatorial configuration generation and a multi-criteria decision-making method for configuration evaluation and selection.This thesis is a step towards a model-based approach for system reconfiguration of evolving systems, ensuring their flexibility and adaptability

Texto completoLo scopo della presente ricerca consiste nella valutazione dei fenomeni di interazione che si vengono a creare nell’accoppiamento di mesh chirurgiche e tessuti e strutture biologiche. La valutazione della compatibilità meccanica tra tessuti e impianto rappresenta un fattore fondamentale per il buon esito dell’intervento. In quest’ottica, risulta necessaria la caratterizzazione meccanica delle mesh chirurgiche che viene condotta attraverso un approccio numerico-sperimentale integrato, in diretta correlazione con le tecniche chirurgiche. Le mesh chirurgiche hanno differente origine e possono essere classificate come sintetiche o biologiche, caratterizzate da particolari proprietà biochimiche e meccaniche e, conseguentemente, da differenti prestazioni. Le mesh biologiche sono ricavate da tessuti ricchi di collagene e possono essere di origine animale (xenograft) o umana (allograft), queste ultime sono principalmente ottenute dal sistema fasciale. Per questo motivo i tessuti fasciali vengono caratterizzati meccanicamente, valutandone il ruolo funzionale in situ in interazione con le circostanti strutture biologiche. Uno specifico modello visco-iperelastico e fibrorinforzato viene utilizzato allo scopo di interpretare il comportamento meccanico dei tessuti biologici, caratterizzati da proprietà di anisotropia, grandi deformazioni e fenomeni dipendenti dal tempo. I parametri costitutivi vengono definiti attraverso la minimizzazione di una funzione costo che esprime la differenza tra dati sperimentali e dati numerici. La tecnica di ottimizzazione, basata sull’algoritmo di ottimizzazione del Simulated Annealing, porta all’individuazione di un set di parametri costitutivi che vengono adottati nella formulazione costitutiva, successivamente implementata nel modello numerico, allo scopo di ottenere un’adeguata descrizione del comportamento meccanico del tessuto in situ. Analisi numeriche sul compartimento anteriore della gamba vengono utilizzate per lo studio della meccanica dei tessuti fasciali di questo distretto. Il compartimento anteriore è di particolare interesse clinico a causa delle diverse patologie a carico di tale regione come, ad esempio, la sindrome compartimentale. La mesh chirurgica Permacol™ viene studiata come esempio di xenograft e caratterizzata attraverso analisi sperimentale e modellazione costitutiva. Tale mesh, comunemente utilizzata nella ricostruzione della parete addominale, è ottenuta da derma suino debitamente decellularizzato e trattato al fine di ottenere cross-links. La mesh Bard® Soft viene studiata in quanto esempio di mesh sintetica leggera in polipropilene, caratterizzata da elevata porosità. L’analisi meccanica di diversi tipi di mesh è fondamentale per la definizione del modello numerico della parete addominale erniata e virtualmente riparata. La ricostruzione della geometria della regione addominale viene effettuata attraverso immagini diagnostiche (MR) e dati di letteratura. Nel testo viene specificata la formulazione costitutiva adottata per la descrizione dei diversi tessuti componenti la regione addominale. Il modello numerico permette una prima valutazione del comportamento meccanico globale della parete addominale integra in condizioni fisiologiche. Successivamente, nel modello, viene introdotta una porta erniaria di posizione e dimensioni compatibili con le evidenze cliniche. Tale difetto viene virtualmente riparato con mesh chirurgiche caratterizzate in diverso modo (biologica e sintetica). Lo scopo consiste nella valutazione dell’interazione meccanica tra mesh chirurgiche e i tessuti biologici, considerandone la compatibilità della risposta meccanica funzionale. Le analisi numeriche permettono di valutare il comportamento della parete addominale sana con quello della parete riparata confrontando i campi di tensione e deformazione di tessuti biologici e mesh chirurgica. Il modello numerico proposto fornisce una prima valutazione degli effetti, indotti dalla presenza della protesi, sul comportamento meccanico globale della parete addominale e fornisce gli strumenti per future valutazioni utili alla pianificazione chirurgica e alla configurazione della protesi. Lo studio proposto si fonda su una forte base sperimentale, essenziale per lo svolgimento delle successive analisi numeriche.

Texto completoEducation researchers are frequently interested in examining the causal impact of academic services and interventions; however, it is often not feasible to randomly assign study elements to treatment conditions in the field of education (Adelson, 2013). When assignment to treatment conditions is non-random, the omission of any variables relevant to treatment selection creates a correlation between the treatment variable and the error in regression models. This is termed endogeneity (Ebbes, 2004). In the presence of endogeneity, treatment effect estimates from traditionally used regression approaches may be biased. The purpose of this study was to investigate the causal impact of an integrated student support model, namely City Connects, on student academic achievement. Given that students are not randomly assigned to the City Connects intervention, endogeneity bias may be present. To address this issue, two novel and underused statistical approaches were used with school admissions lottery data, namely Gaussian copula regression developed by Park and Gupta (2012), and Latent Instrumental Variable (LIV) regression developed by Peter Ebbes (2004). The use of real-world school admissions lottery data allowed the first-ever comparison of the two proposed methods with Instrumental Variable (IV) regression under a large-scale randomized control (RCT) trial. Additionally, the researcher used simulation data to investigate both the performance and boundaries of the two proposed methods compared with that of OLS and IV regression. Simulation study findings suggest that both Gaussian copula and LIV regression are useful approaches for addressing endogeneity bias across a range of research conditions. Furthermore, simulation findings suggest that the two proposed methods have important differences in their set of identifying assumptions, and that some assumptions are more crucial than others. Results from the application of the Gaussian copula and LIV regression in the City Connects school lottery admissions study demonstrated that receiving the City Connects model of integrated student support during elementary school has a positive impact on mathematics achievement. Such findings underscore the importance of addressing out-of-school barriers to learning

Texto completoInfectious diseases are a leading cause of morbidity and mortality worldwide. Despite significant advancement in our understanding of infectious disease biology, existing microbiologic diagnostic tests often fail to identify etiologic pathogens in cases of suspected infection. Metagenomic next-generation sequencing (mNGS) offers the potential for a universal pathogen detection method, but analysis and interpretation of findings are challenging. This is especially true for lower respiratory tract infections (LRTIs) where mNGS data interpretation is complicated by the existence of a respiratory microbiome composed of pathobionts present in both health and disease.
To address the need for improved LRTI diagnostics, we first compared two fluid types commonly used for diagnosis of LRTI, showing that despite moderate microbiome differences, both mini-bronchioalveolar lavage (mBAL) and tracheal aspirate (TA) samples are suitable for identification of pathogens in the context of an infection. Then, we evaluated the utility of mNGS as a diagnostic for LRTI in a cohort of 92 TA samples from adults with acute respiratory failure. We developed methods for sifting putative pathogens from commensal microbiota as well as pathogen, microbiome diversity, and host gene expression metrics to identify LRTI-positive patients and differentiate them from critically ill controls with noninfectious acute respiratory illnesses. We applied the models developed for evaluation of LRTI status to several other cohorts and disease contexts to show their broad applicability.
The low sensitivity of existing clinical diagnostics results in an imperfect gold standard, complicating the development of mNGS-based biomarkers. We explored the impact of label noise on host gene expression classifiers and methods for circumventing the issue. First, we tested whether label-noise robust logistic regression approaches could improve classifier performance by enabling the use of a larger training set. Then, we tested whether variational autoencoders, an unsupervised dimensionality reduction approach, could generate novel insight from combined host and microbial mNGS data. Altogether, this work suggests that a single streamlined protocol offering an integrated genomic portrait of pathogen, microbiome, and host transcriptome may hold promise as a tool for diagnosis of infections and contextualization of patient response.

Texto completoThis thesis aimed to identify evidence of a holistic approach in the managerial practices of companies, contribute to the construction of a model with holistic characteristics to guide the design of managerial practices, and classify companies in regards to the the institutionalization stage of the use of elements of holistic approach in their practices. Holism has ancient roots, but its modern meaning was defined by South African thinker and statesman J.C. Smuts, in his book Holism and Evolution, published in 1926. Smuts considers holism as a factor that guides the evolution of the entire universe, with the formation of structures that can only be properly treated as wholes , in a sequence which starts with matter and life, continues through human personality, and finally reaches supra-individual organizations and human value systems. In epistemological terms, holism opposes reductionism, be it in Natural Sciences (atomism), and in Social Sciences (individualism). After Smuts, several authors explored holism, such as Quine (1951), Weil (1991), Esfeld (2001) and Descombes (2014). In regards to Administration, Savory (1999) approaches holism with particular focus on environmental issues. In Brazil, Almada et al (2004), Aligleri et al (2008), Cunha e Corrêa (2010), among others, with focus in different administrative activities, have made allusions which explore holistic approaches in management, such as viewing the companies as totalities, as well as the connections between those totalities. This qualitative, exploratory and descriptive research utilized an interpretative approach, which helped the researcher understand a reality which contains objective as well as subjective aspects. Twenty companies were researched, chosen randomly among companies within the Novo Mercado segment of the BM&F Bovespa (São Paulo Stock Exchange), which has strict corporate rules. Data was collected in the companies\' annual reports and other documents available in the companies\' websites. Information collected was not restricted to general data about the companies, but also included managerial practices, sustainability and corporate and social responsibility. The Theory of Institutionalization provided criteria to classify companies, in various stages of institutionalization, in regards to the use of holistic approach in their practices. In order to obtain this classification, it was necessary to build a model, or prototype for holistic evaluation, as no such model had been found in previous studies. This prototype, the first result of the research, was built through comparisons between holistic principles, taken from the work of Smuts, with the Theory of Systems, the Theory of Cybernetics and Complexity, and the Theory of Stakeholders. After careful analysis of the companies\' practices, the research suggests that future studies should include an evaluation of the companies\' holistic approach of their activities and social endeavors. Also observed were different evolution mechanisms and factors that could limit this evolution. Finally, it was possible to present, based on deductions on data and theories, a hypothesis to be tested that companies can benefit by utilizing holistic approach in their practices. This study fills an important void in modern business theories, helping companies deal with a complex world using rational tools, which do not harm the complexity of the holistic nature of reality.
