Abstract.The subject of entrepreneurship is an area in constant evolution, is a valid form of combating the phenomenon of unemployment, representing a virtuous response against a labor market that requires high flexibility to all parties who work there. For Schwartz “value” is a concept that an individual has a trans-situational purpose, he argues that the values being desirable states transcend specific situations and depict regulatory models used to judge and choose between different ways of behaving, so act from the principles driving in people’s lives. The present study aims to investigate the presence of significant relationships between the variables related to entrepreneurial skills and values . The sample is represented by a group of 101 Italian workers including 85 men ( 84%) and 15 women (16 %), all day between the ages of 30 and 39 who work in the public transport company ATAC S.p.A. The focus of this study is represented by the subject and his being intra-company both within the working environment, with its action and its influence on the economy and the social reality in which it operates.Keywords: Intrapreneurship,organizations, valuesAbstract.Il tema dell’imprenditorialità è un’area in costante evoluzione, la quale viene coinvolta ed utilizzata sia dalla disciplina psicologica, economica,ma anche sociale per ovviare al fenomeno della disoccupazione. Un altro costrutto preso in considerazione è il ‘’valore’’il quale secondo Schwartz è un concetto che un individuo ha di uno scopo transituazionale, egli sostiene che i valori essendo stati desiderabili trascendono le specifiche situazioni e raffigurano modelli normativi impiegati per giudicare e scegliere tra diversi modi di comportarsi, e fungono, quindi, da principi guida nella vita delle persone. La presente ricerca si pone l’obiettivo di indagare la presenza di relazioni significative tra le variabili legate alle competenze imprenditoriali ed i valori, secondo la teoria di riferimento legata ai valori di Schwarz, S. H. e Bilsky, W. (1987). Partendo da quanto proposto da Lidaka (2012), ci si propone di individuare influenze significative da parte dei valori, sui tratti imprenditoriali considerati nella presente ricerca.Si vogliono pertanto esplorare i legami tra questi due aspetti fondamentali dell’essere umano: valori da una parte, tratti caratteriali e competenze imprenditoriali, dall’altra.Il campione è rappresentato da un gruppo di 101 soggetti, ai quali è stato misurato, attraverso la somministrazione del questionario, sia i valori che le competenze imprenditoriali che si inseriscono nella scelta lavorativa. I dati sono stati raccolti su un campione di 101 lavoratori italiani di cui 85 uomini (84%) e 15 donne (16%), tutti dì età compresa tra i 30 ed i 39 anni. Il focus di questo studio, dunque, è rappresentato dal soggetto e dal suo essere intraimprenditoriale all’interno del contesto lavorativo, dalla sua azione e dall’influenza sull’economia e sulla realtà sociale nella quale opera (Battistelli, Favretto, 2003).Keywords: Intrapreneurship- Entrepreneurship- Values- Locus of control- Self-efficacy-Engagment- Employ-ability- Proactive personality.

AbstractA Finite Element workflow for the multiscale analysis of the aortic valve biomechanics was developed and applied to three physiological anatomies with the aim of describing the aortic valve interstitial cells biomechanical milieu in physiological conditions, capturing the effect of subject-specific and leaflet-specific anatomical features from the organ down to the cell scale. A mixed approach was used to transfer organ-scale information down to the cell-scale. Displacement data from the organ model were used to impose kinematic boundary conditions to the tissue model, while stress data from the latter were used to impose loading boundary conditions to the cell level. Peak of radial leaflet strains was correlated with leaflet extent variability at the organ scale, while circumferential leaflet strains varied over a narrow range of values regardless of leaflet extent. The dependency of leaflet biomechanics on the leaflet-specific anatomy observed at the organ length-scale is reflected, and to some extent emphasized, into the results obtained at the lower length-scales. At the tissue length-scale, the peak diastolic circumferential and radial stresses computed in the fibrosa correlated with the leaflet surface area. At the cell length-scale, the difference between the strains in two main directions, and between the respective relationships with the specific leaflet anatomy, was even more evident; cell strains in the radial direction varied over a relatively wide range ($$0.36-0.87$$ 0.36 - 0.87 ) with a strong correlation with the organ length-scale radial strain ($$R^{2}= 0.95$$ R 2 = 0.95 ); conversely, circumferential cell strains spanned a very narrow range ($$0.75-0.88$$ 0.75 - 0.88 ) showing no correlation with the circumferential strain at the organ level ($$R^{2}= 0.02$$ R 2 = 0.02 ). Within the proposed simulation framework, being able to account for the actual anatomical features of the aortic valve leaflets allowed to gain insight into their effect on the structural mechanics of the leaflets at all length-scales, down to the cell scale.

The STEAM educational model is based on the idea of teaching students 5 specific fields of Science ( Teshology) , Enerineering ( Energineering), Art (Art), Mathematics ( Marth) in a joint and integrated way. The teaching of biology at school is based on regular demonstrations of experience. However, it is difficuit for students with figurative memory to leam abstract, pictureless processes. My observations today give grounds to say that the teaching of Biology with the help of STEAM will become more difficuit in order to solve these problems and achieve the active use of internet resources in the teaching process. Learning biology through STEAM wil play an important role in education and prepare children for future challenges and opportunities/ It will develop the skills of rapid learning that are needed in educational institutions and today.

The issue of terrorism is the subject of numerous studies and analyses. They are usually devoted to its individual manifestations, forms or mechanisms and relatively rarely concern the reasons for the presence and escalation of terrorism. What is more, they often focus on indicating the main factors that trigger terrorism while lacking a profound analysis or attempts at the systemization of the sources of terrorism. Another drawback lies in the emotional or even ideological approach to the subject, which obviously limits the scientific merit of such considerations. Considering the reasons for terrorism one needs to ask several key questions. What are the main factors that generate terrorism? Is it possible to indicate one or several dominating deter- minants among the sources of terrorism? How can they be arranged? Do the present typologies of reasons for terrorism take into account the comprehensive range and specific na- ture of this phenomenon? Apart from answering the above questions, the main purpose of this study is to indicate the main reasons for terrorism combined with the author’s attempt to systemize them by means of the interferential model of reasons for terrorism. It encompasses both the sources of terrorism and their mutual relations, the factors that affect terrorism and the mechanisms and changes that occur with respect to these phenomena.

Despite recent innovations in exoskeleton design and control, predicting subject-specific impacts of exoskeletons on gait remains challenging. We evaluated the ability of three classes of subject-specific phase-varying (PV) models to predict kinematic and myoelectric responses to ankle exoskeletons during walking, without requiring prior knowledge of specific user characteristics. Each model—PV, linear PV (LPV) and nonlinear PV (NPV)—leveraged Floquet theory to predict deviations from a nominal gait cycle due to exoskeleton torque, though the models differed in complexity and expected prediction accuracy. For 12 unimpaired adults walking with bilateral passive ankle exoskeletons, we predicted kinematics and muscle activity in response to three exoskeleton torque conditions. The LPV model's predictions were more accurate than the PV model when predicting less than 12.5% of a stride in the future and explained 49–70% of the variance in hip, knee and ankle kinematic responses to torque. The LPV model also predicted kinematic responses with similar accuracy to the more-complex NPV model. Myoelectric responses were challenging to predict with all models, explaining at most 10% of the variance in responses. This work highlights the potential of data-driven PV models to predict complex subject-specific responses to ankle exoskeletons and inform device design and control.

The aim of the present thesis was to investigate the influence of lower-limb joint models on musculoskeletal model predictions during gait.
We started our analysis by using a baseline model, i.e., the state-of-the-art lower-limb model (spherical joint at the hip and hinge joints at the knee and ankle) created from MRI of a healthy subject in the Medical Technology Laboratory of the Rizzoli Orthopaedic Institute. We varied the models of knee and ankle joints, including: knee- and ankle joints with mean instantaneous axis of rotation, universal joint at the ankle, scaled-generic-derived planar knee, subject-specific planar knee model, subject-specific planar ankle model, spherical knee, spherical ankle. The joint model combinations corresponding to 10 musculoskeletal models were implemented into a typical inverse dynamics problem, including inverse kinematics, inverse dynamics, static optimization and joint reaction analysis algorithms solved using the OpenSim software to calculate joint angles, joint moments, muscle forces and activations, joint reaction forces during 5 walking trials. The predicted muscle activations were qualitatively compared to experimental EMG, to evaluate the accuracy of model predictions.
Planar joint at the knee, universal joint at the ankle and spherical joints at the knee and at the ankle produced appreciable variations in model predictions during gait trials. The planar knee joint model reduced the discrepancy between the predicted activation of the Rectus Femoris and the EMG (with respect to the baseline model), and the reduced peak knee reaction force was considered more accurate. The use of the universal joint, with the introduction of the subtalar joint, worsened the muscle activation agreement with the EMG, and increased ankle and knee reaction forces were predicted. The spherical joints, in particular at the knee, worsened the muscle activation agreement with the EMG. A substantial increase of joint reaction forces at all joints was predicted despite of the good agreement in joint kinematics with those of the baseline model. The introduction of the universal joint had a negative effect on the model predictions. The cause of this discrepancy is likely to be found in the definition of the subtalar joint and thus, in the particular subject’s anthropometry, used to create the model and define the joint pose.
We concluded that the implementation of complex joint models do not have marked effects on the joint reaction forces during gait. Computed results were similar in magnitude and in pattern to those reported in literature. Nonetheless, the introduction of planar joint model at the knee had positive effect upon the predictions, while the use of spherical joint at the knee and/or at the ankle is absolutely unadvisable, because it predicted unrealistic joint reaction forces.

Thesis (PhD (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2010.ENGLISH ABSTRACT: A methodology to facilitate analysis of dynamic subject-specific patellofemoral function is presented. An enhanced understanding of patellofemoral biomechanics will enable orthopaedic surgeons to identify the mechanisms responsible for imbalances in the joint stabilisers, while also providing objective information on which to base treatment methods. Dynamic patellofemoral function of three volunteers was simulated with a musculoskeletal computational model. The individuals underwent scans from which three-dimensional models of their patellofemoral joints were constructed. Skeletal muscles and soft tissue stabilisers were added to the skeletal models, after which subject-specific motion was simulated. After trochlear engagement, the patellae of the volunteers followed a lateral path, whereas patella tilt was subject-specific. Comparison of the predicted tilt and mediolateral position values at 30 degrees knee flexion to in-vivo MRI values showed a mean accuracy of 62.1 % and 96.9 % respectively. The patellofemoral contact load . quadriceps tendon load ratio varied between 0.7 and 1.3, whereas the mediolateral load component . resultant load ratio ranged between 0 and 0.4. Both parameters. values were similar to previous findings. The medial patellofemoral ligament tension decreased with knee flexion, while the patellar tendon-quadriceps tendon ratio followed a similar trend to that of previous findings (varied between 0.4 and 1.2). After induction of a tubercle osteotomy in the coronal plane, Volunteer One.s patella engaged the trochlear groove at an earlier knee flexion angle, while the patella of Volunteer Two only underwent a small medial displacement. Finite element analyses were employed to investigate the influence of the osteotomy on the patellofemoral pressure distribution. The mean pressure in Volunteer One.s patellofemoral joint was alleviated (17 % smaller) at all angles of flexion with the exception of 60 degrees (12 % greater). Pressure in Volunteer Two.s joint was alleviated at 30 and 45 degrees knee flexion (6 % smaller), while it was elevated (9.1 % greater) at other angles of flexion. Two commercial patellofemoral prostheses were tested on the three Volunteers. joints in the virtual environment. Prosthesis Two delivered patella shift and tilt patterns similar to the baseline values. Patellar tendon tension was slightly greater after resurfacing, with the tensions elevated most with Prosthesis Two. Medial patellofemoral ligament tension was reduced most with Prosthesis Two, while lateral retinaculum tension was increased slightly. Prosthesis Two was the best candidate to reproduce patella kinematics, while the patellofemoral kinetics was largely independent from the type of prosthesis used. The prostheses performed worse for Volunteer Three, supporting the need for the development of patient-specific prostheses. Three validated subject-specific musculoskeletal models facilitated the analysis of the individuals. patellofemoral biomechanics. The technique can potentially be employed by orthopaedic surgeons to visualise the change that an osteotomy or patellofemoral arthroplasty might induce on an individual.s patellofemoral joint. This technique might aid in the development of a tool to assist biomedical engineers in the development of new patellofemoral prostheses. Most importantly, the outcome of surgical intervention may be predicted beforehand, and a treatment procedure may be tailored to optimally fit the patellofemoral biomechanics of that individual.
AFRIKAANSE OPSOMMING: 'n Ondersoekmetode van die dinamiese gedrag van pasiënt-spesifieke patellofemorale gewrigte word beskryf. Indien die patellofemorale biomeganika beter verstaan word, kan ortopediese chirurge die meganismes wat verantwoordelik is vir oneffektiewe stabiliseerders identifiseer en behandeling op objektiewe bevindinge baseer. Die dinamiese patellofemorale funksie van drie vrywilligers is gesimuleer m.b.v. `n spier-skelet rekenaarmodel. Drie-dimensionele modelle van die individue se patellofemorale gewrig is gekonstrueer m.b.v. skanderings. Die skeletspiere en sagte ondersteuningsweefsel is tot die model toegevoeg, voordat vrywilliger-spesifieke beweging gesimuleer is. Die knieskywe van die vrywilligers het `n laterale pad gevolg nadat dit die groef binnegetree het, met die tiltwaardes uniek vir elke vrywilliger. Vergelyking van die beraamde knieskyf mediolaterale tilt en posisies by 30 grade fleksie met in-vivo magnetiese resonansieskandering waardes het `n akkuraatheid van 62.1 % en 96.9 % respektiewelik getoon. Die patellofemorale kontaklas-kwadriseps seningspanning verhouding het gewissel tussen 0.7 en 1.3; asook die mediale komponent – resultante komponent patellofemorale kontaklas wat gewissel het tussen 0 en 0.4. Beide parameters se waardes was soortgelyk aan voorheen-gepubliseerde data. Die mediale patellofemorale ligamentspanning het afgeneem met fleksie. Die patella sening-kwadriseps seningspanning verhouding was soortgelyk aan vorige gepubliseerde waardes en het gewissel tussen 0.4 en 1.2. Nadat 'n tuberkel-osteotomie in die koronale vlak aangebring is, het Vrywilliger Een se patella die femorale groef vroeër binnegetree. Vrywilliger Twee se patella het slegs `n mediale verskuiwing ondergaan. Eindige element analises is ingespan om die effek van die osteotomie op die spanningsverspreiding in die patellofemorale gewrig te ondersoek. Die gemiddelde spanning in Vrywilliger Een se gewrig was minder by alle hoeke van fleksie (17 % minder), met uitsondering van die spanning by 60 grade (12 % meer). Die spanning in Vrywilliger Twee se gewrig was minder by 30 en 45 grade (6 % minder), maar hoër by ander hoeke (9.1 % meer). Twee kommersiële patellofemorale prosteses is getoets op die drie Vrywilligers d.m.v. die model. Prostese Twee het die knieskyf-kinematika die beste nageboots. Die patella-seningspanning was effens groter na die vervanging. Prostese Twee het gesorg vir die grootste toename. Die mediale patellofemorale ligamentspanning was die kleinste toe Prostese Twee gebruik is, maar dit het gesorg vir effense hoër laterale retinakulumlaste. Die analises het getoon dat Prostese Twee die beste kandidaat is om die korrekte kinematika te herbewerkstellig. Die kinetika daarteenoor was onafhanklik van die tipe prostese wat gebruik is. Geeneen van die twee prosteses was geskik vir Vrywilliger Drie nie, wat as motivering vir die ontwikkeling van pasiënt-spesifieke prosteses dien. Drie bekragtigde vrywilliger-spesifieke spier-skelet modelle het die analise van patellofemorale biomeganika bewerkstellig. Die tegniek het die potensiaal om ortopediste in staat te stel om die effek van `n osteotomie of patellofemorale vervanging te visualiseer. Die tegniek kan verder gebruik word deur biomediese ingenieurs in die vervaardiging van nuwe patellofemorale prosteses. Meer belangrik is die feit dat die resultaat van chirurgiese ingryping voorspel kan word en optimale behandelingsprosedures beplan kan word vir die patellofemorale biomeganika van `n individu.

Full textAbstract:
2008/2009La predizione del rischio di frattura costituisce un elemento di estremo interesse in ambito clinico quale supporto dei processi diagnostici, di prognosi e di cura; attualmente la valutazione è basata su inferenze statistiche rispetto al contenuto minerale del tessuto osseo in siti specifici a mezzo di speciali immagini radiografiche, realizzandosi valutazioni caratterizzate da un consistente margine di incertezza. Un significativo miglioramento è ragionevole pensare possa derivare dall'uso di modelli numerici tridimensionali subject specific che, fondandosi su immagini diagnostiche, riescano a cogliere le peculiarità morfologiche e costitutive di ogni singolo caso. Ad oggi è stata sviluppata una metodologia di modellazione basata sul Metodo degli Elementi Finiti (FEM) che si è dimostrata precisa nel replicare misure sperimentali su segmenti ossei in vitro; la procedura si basa sulla precisa definizione topologica della superficie dell'osso, e risulta per questo estremamente laboriosa e significativamente impegnativa sia in termini di tempo che di competenze specializzate necessarie; questo fatto ne limita l’uso nella pratica clinica a causa della difficile applicazione su larga scala in tempi contenuti. Scopo della tesi era l’esplorazione di un approccio di modellazione alternativo, in grado di conservare i requisiti di robustezza, accuratezza e generalità della procedura FEM, ma in grado di aumentare il grado di automazione del processo di studio. L’indagine si è concentrata su implementazioni innovative del Metodo delle Celle (CM), un metodo numerico basato sulla formulazione discreta diretta delle equazioni dei campi fisici adatto a studiare sistemi non omogenei e di complessa geometria. Il rifiuto dell'ipotesi di continuo alla base del CM lo rendeva a priori filosoficamente concorde con la natura della sorgente di informazione (le immagini diagnostiche) su cui la procedura di modellazione automatizzata si sarebbe dovuta basare. L'elaborato esplora alcune ipotesi fondate su implementazioni numeriche innovative derivate del Metodo delle Celle: sono stati sviluppati, nella loro impostazione formale e implementativa, tre differenti approcci meshless del CM, approcci nei quali la soluzione viene calcolata in punti tra i quali non è richiesta la definizione di una connettività a livello globale. I tre metodi, accomunati dalla scrittura di un'equazione di bilancio scritta su un area tributaria di nodo definita localmente, sono stati valutati nella prospettiva applicativa del problema di riferimento. Uno di questi approcci, basato sulla creazione di un complesso locale di celle primali, si è dimostrato adatto ad essere applicato nella creazione di modelli numerici automaticamente costruiti sui dataset di immagini diagnostiche. Questa metodologia, denominata Meshless Cell Method (MCM), è stata valutata nella sua applicabilità replicando delle misure sperimentali di deformazione su un esemplare di femore in vitro. La buona capacità di predire i valori sperimentali, malgrado la ridotta risoluzione delle immagini diagnostiche di partenza, ne ha giustificato un più solido e ampio processo di validazione: misure sperimentali di deformazione in vitro in 15 differenti siti anatomici di 8 esemplari di femore in 6 distinte configurazioni hanno costituito l'elemento di confronto rispetto a cui sono state valutate le predizioni dei corrispondenti modelli MCM; ulteriore elemento di valutazione comparativa è stato offerto dalle predizioni di modelli FEM replicanti le stesse prove sperimentali. L'analisi ha evidenziato la buona capacità dei modelli MCM di identificare la realtà sperimentale: il coefficiente di correlazione, i parametri della retta di regressione e gli scarti medio e massimo rispetto alle misure sperimentali si sono dimostrati paragonabili a quanto realizzato dai modelli FEM. Lo studio ha individuato dunque un processo di modellazione numerica di segmenti ossei caratterizzato da un elevato grado di automaticità: il modello numerico viene costruito direttamente sul dataset CT in maniera indipendente dallo specifico segmento osseo rappresentato; la procedura non richiede alcuna manipolazione e si è dimostrato poter ottenere accuratezze nella replicazione delle misure sperimentali in vitro assolutamente concordi con quelle della procedura FEM di riferimento. Il lavoro si colloca nel contesto dell’attività di ricerca del Laboratorio di Tecnologia Medica dell’Istituto Ortopedico Rizzoli di Bologna, struttura presso cui lo studio è stato condotto.

The knee is one of the most complex and studied joint of the musculoskeletal system provided its great importance in locomotion. Therefore, a deep understanding of its behaviour and of the role played by each of the structures composing it is fundamental. Knee joint models are an invaluable tool to understand the behaviour of the knee and their usefulness is proved in many fields such as surgical planning and prosthetic design. A huge amount of models has been proposed in the literature focusing on the kinematic, the kinetostatic and the dynamic behavior of the joint. Models can be based on in vivo or in vitro data. While the kinematic and the kinetostatic models are defined properly on in vitro data, the dynamic ones cannot. This discrepancy leads to a gap, a lack of coherence, between the usually in vitro defined kinematic and kinetostatic models and the study of the active structures of the joint. In order to achieve a comprehensive knee joint description in which the kinematic, kinetostatic and dynamic models coherently stem one from the other, the identification of a procedure that allows to obtaining reliable kinematic and kinetostatic models in vivo is needed. In the present dissertation a procedure is defined that allows for the identification of a subject specific knee joint model in vivo starting from standard clinical data obtained by the use of non invasive techniques such as computed tomography (CT), magnetic resonance imaging (MRI) and fluoroscopy. This procedure leads to an accurate identification of the parameters needed to personalize the 5-5 parallel mechanism and its patello-femoral extension on a single patient in order to accurately reply the knee joint original motion. Furthermore, following the sequential approach to the modelling of the joint, a stiffness model of the knee is specialized on the specific subject's anatomy.

Full textAbstract:
The upper-airway complex is involved in a number of life-sustaining functions, such as swallowing, speech, breathing and chewing. Disorders associated with these functions can dramatically reduce the life quality of the suffers. Biomechanical modelling is a useful tool that can bridge the gap between the human knowledge and medical data.When tailored to individual patients, biomechanical models can augment the imaging data, to enable computer-assisted diagnosis and treatment planning.
This thesis introduces a model-registration framework for creating subject-specific models of the upper-airway complex based on 3D medical images.Our framework adapts a state-of-art comprehensive biomechanical model of head and neck, which represents the generic upper-airway anatomy and function. By morphing this functional template to subject-specific data, we create upper-airway models for particular individuals. In order to preserve the functionality of the comprehensive model, we introduce a multi-structure registration technique, which can maintain the spatial relationship between the template components, and preserve the regularity of the underlying mesh structures. The functional information, such as the muscle attachment positions, joint positions and biomechanical properties, is updated to stay relevant to the subject-specific model geometry. We demonstrate the functionality of our subject-specific models in the biomechanical simulations.
Two illustrative case studies are presented. First, we apply our modelling methods to simulating the normal swallowing motion of a particular subject based on the kinematics (of the airway boundary, jaw and hyoid) extracted from dynamic 3D CT images. The results suggest that our model tracks the oropharyngeal motion well, but has limited ability to reproduce the hyolaryngeal movements of normal swallowing. Second, we create two speaker-specific models based on 3D MR images, and perform personalized speech simulations of the utterance ageese. The models reproduce the speech motion of the tongue and jaw recorded in tagged and cine MRI data with sub-voxel tracking error, predict the muscular coordinating patterns of the speech motion.
This study demonstrates the feasibility of using template-based subject-specific modelling methods to facilitate personalized analysis of upper-airway functions. The proposed model-registration framework provides a foundation for developing a systematic and advanced subject-specific modelling platform.Applied Science, Faculty of

Full textAbstract:
Osteoporosis related bone fractures and osteoarthritis affect the lifes of millions of people in the world and constitute a significant burden on the healthcare systems of several countries. It is believed that mechanical actors such as excessive joint loading during daily activities might play a role in their onset. Predictive methods based on computational modelling could identify the early development of such diseases and, among these techniques, the multiscale modelling approach shows promising potential in view of its capability to describe the musculoskeletal (MSK) system across different spatial and temporal levels. The development of a multiscale model of the MSK system, however, poses great computational challenges and requires the determination of multiscale links such as the joint contact pressure, which is typically predicted by means of computationally expensive methods such as the finite element method. An accurate low cost alternative is represented by the discrete element method (DEM), a computational method in which a spring mattress is used to describe the contact interactions within the joints. The method, however, has been developed for static cases and does not offer the possibility of tracking the physiological motion of the contacting bones over time. Furthermore, time dependent properties such as viscoelasticity are often neglected within these frameworks. This thesis aims at extending the discrete element method (EDEM) to track the bone motion and include the viscoelastic phenomena. The methodology is used, in conjunction with subject specific MSK models, for the development of subject specific ankle models to compute the contact pressure during gait. Evaluation of EDEM and DEM outputs found that not considering the physiological displacement of the talus causes an underestimation of the joint pressure distribution, while the peak values remain substantially unaffected. Comparison against experimental pressure data shows that EDEM can identify the patterns of pressure in cadaveric ankle specimens. Finally, the viscoelastic formulation of EDEM proved successful in describing the typical creep behaviour of articular cartilage.

‘Causal modelling’ is a general term that applies to a wide variety of formal methods for representing, and facilitating inferences about, causal relationships. The end of the twentieth century saw an explosion of work on causal modelling, with contributions from such fields as statistics, computer science, and philosophy; as well as from more subject-specific disciplines such as econometrics and epidemiology. This article focuses on two programmes that have attracted considerable philosophical attention, one due to the computer scientist Judea Pearl and his collaborators, and the other to the philosophers Peter Spirtes, Clark Glymour, and Richard Scheines. It offers a much simplified presentation of causal models that emphasizes various points of philosophical interest.

Full textAbstract:
This chapter provides a tutorial on how economics can be used to model the interaction between users and systems. Economic theory provides an intuitive and natural way to model Human-Computer Interaction which enables the prediction and explanation of user behaviour. A central tenet of the approach is the utility maximisation paradigm where it is assumed that users seek to maximise their profit/benefit subject to budget and other constraints when interacting with a system. By using such models it is possible to reason about user behaviour and make predictions about how changes to the interface or the users interactions will affect performance and behaviour. In this chapter, we describe and develop several economic models relating to how users search for information. While the examples are specific to Information Seeking and Retrieval, the techniques employed can be applied more generally to other human-computer interaction scenarios. Therefore, the goal of this chapter is to provide an introduction and overview of how to build economic models of human-computer interaction that generate testable hypotheses regarding user behaviour which can be used to guide design and inform experimentation.

An artwork picturing biblical subject matter is never a straightforward depiction of a scriptural text. It is a visual translation of it, shaped by available models of interpretation, the aesthetic styles and visual cultures of the era, and the cultural contexts of its production, display, circulation, and reception. This chapter analyzes specific examples of American art to showcase the four primary functions performed by biblical subject matter throughout the nation’s history: to deliver moral instruction, engage sociopolitical concerns, assert communal identity, and render cultural criticism. The expansive and varied visual landscape that results testifies to the bible’s centrality in American art history.

Full textAbstract:
Many theorists defend relationship contracts. Some argue that enforceable relationship contracts should be available alongside existing or reformed state-recognized marriage, and available to either married or unmarried couples. Other theorists argue that relationship contracts are the best sort of legal regulation to replace marriage. It is this latter question that is the subject of this chapter. The chapter contrasts contract and directive models of regulation, and notes that contract appears more compatible with liberty than does directive. However, this appearance is illusory since contracts can undermine liberty, directives can enhance liberty, and even a contract regime requires default directives. Moreover, there are various problems with the enforcement of relationship contracts: neither specific performance nor compensatory alimony are good solutions. Relational contract theory attempts to deal with some of these problems but has its own limitations. The chapter concludes that contract is not the best replacement for marriage.

Full textAbstract:
Grounded in a research-based, conceptual model called Technological Pedagogical and Content Knowledge (TPACK), the essential premise of Music Learning Today: Digital Pedagogy for Creating, Performing, and Responding to Music is that music educators and their students can benefit through use of technology as a tool to support learning in the three musical processes—creating, performing, and responding to music. Insights on how technology can be used to advantage in both traditional and emerging learning environments are provided, and research-based pedagogical approaches that align technologies with specific curricular outcomes are described. Importantly, the book advocates that the decision on whether or not to utilize technology for learning, and the specific technology that might be best suited for a particular learning context, should begin with a consideration of curricular outcomes (music subject matter). This is in sharp contrast to most other books on music technology that are technocentric, organized around specific software applications and hardware. The book also recognizes that knowing how to effectively use the technological tools to maximize learning (pedagogy) is a crucial aspect of the teaching-learning process. Drawing on the research and promising practices literature in music education and related fields, pedagogical approaches that are aligned with curricular outcomes and specific technologies are suggested. It is not a “how to” book per se, but rather a text informed by the latest research, theories of learning, and documented best practices, with the goal of helping teachers develop the ability to understand the dynamics of effectively using technology for music learning.

Full textAbstract:
Quantum field theory has become the universal language of most modern theoretical physics. This book is meant to provide an introduction to this subject with particular emphasis on the physics of the fundamental interactions and elementary particles. It is addressed to advanced undergraduate, or beginning graduate, students, who have majored in physics or mathematics. The ambition is to show how these two disciplines, through their mutual interactions over the past hundred years, have enriched themselves and have both shaped our understanding of the fundamental laws of nature. The subject of this book, the transition from a classical field theory to the corresponding Quantum Field Theory through the use of Feynman’s functional integral, perfectly exemplifies this connection. It is shown how some fundamental physical principles, such as relativistic invariance, locality of the interactions, causality and positivity of the energy, form the basic elements of a modern physical theory. The standard theory of the fundamental forces is a perfect example of this connection. Based on some abstract concepts, such as group theory, gauge symmetries, and differential geometry, it provides for a detailed model whose agreement with experiment has been spectacular. The book starts with a brief description of the field theory axioms and explains the principles of gauge invariance and spontaneous symmetry breaking. It develops the techniques of perturbation theory and renormalisation with some specific examples. The last Chapters contain a presentation of the standard model and its experimental successes, as well as the attempts to go beyond with a discussion of grand unified theories and supersymmetry.

While the twenty-first century has brought a wealth of new digital resources for researching late eighteenth- and early nineteenth-century serials, the subfield of Romantic periodical studies has remained largely inchoate. This collection sets out to begin tackling this problem, offering a basic groundwork for a branch of periodical studies that is distinctive to the concerns, contexts and media of Britain’s Romantic age. Featuring eleven chapters by leading experts on the subject, it showcases the range of methodological, conceptual and literary-historical insights to be drawn from just one of the era’s landmark literary periodicals, Blackwood’s Edinburgh Magazine. Drawing in particular on the trove of newly digitised content, specific essays model how careful analyses of the incisive and often inflammatory commentary, criticism and original literature from Blackwood’s first two decades (1817–37) might inform and expand many of the most vibrant contemporary discussions surrounding British Romanticism.

Rural areas are subject to constant structural, spatial and economic transformations. The main purpose of this monograph was to present a new concept of shaping of rural land arrangement that takes into account the land value. The presented optimization methodology of shaping of the rural areas has a general range of application, not being limited by time or place. of the location of the consolidation object. The only condition for its use is the availability of a specific set of output data enabling the necessary calculations for the implementation of consolidation works. The described method has been successfully applied to the research object of the Mściowojów village, in a registry area located in the Dolnośląkie voivodeship, in the Jaworski district, providing with the assumed effects. In order to meet the research objectives, the shaping of rural land arrangement was conducted according to five models. The original arrangement of existing land division in a given village is considered as the 1st model. The 2nd model uses a rather accurate description of the locations of the lands in the village. To define this feature the location of farm parcels had to be determined. This model is the most accurate, but also the most labor-intensive of all. In the 3rd model, a fundamental simplification of the land arrangement was adopted, limiting the distance matrix to its measurement to the entry points from the settlements into the complexes. This simplification means that the location of parcels in the complex does not affect the average distance to the land in the whole village. On the basis of simplifications applied in the 3rd model allowing a significant reduction of the distance matrix the 4th model which uses a linear programming to minimize the distance to a parcel was developed. Introducing into the linear model an additional condition that eliminates distance growth in farms in relation to the initial state was important for the research. This was implemented in the 5th model and had a positive impact on the obtained results. The 6th model was developed by including the landowners' wants into the 5th model. These had to be taken into account so that the research/the new land arrangement did not cause complaints. The wants could not be fully included due to their inherently contradictory nature. The wants for having the parcel in a given arrangement was replaced with a guarantee of division, after which landowner receives no smaller share than the prior one. As demonstrated in the work, the solutions of the developed models allowed obtaining land arrangements close to the optimal in terms of distance to land and the shape of parcels and farms with regard to land specifics. The presented results allow to draw a conclusion that the methods and analyses applied in the research can have a wide range of application in shaping of rural land arrangement. Developing the most socially accepted optimization of parcel division in the process of land consolidation is important due to the actual needs for the implementation of the rural land arrangement research. This may also have influence on better use of the EU's financial resources for the consolidation of agricultural lands.

AbstractIntroduction: Transcranial magnetic stimulation (TMS) is a major noninvasive neurostimulation method in which a coil placed near the head employs electromagnetic induction to produce electric fields and currents within the brain. To predict the actual site of stimulation, numerical simulation of the electric fields within the head using high-resolution subject-specific head models is required. A TMS modeling software toolkit has been developed based on the boundary element fast multipole method (BEM-FMM), which has several advantages over conventional finite element method (FEM) solvers.Objective: To extend the applicability of the BEM-FMM TMS simulation toolkit to head models whose meshing scheme produces a single mesh for every unique tissue instead of producing a single mesh for every unique tissue/tissue boundary.Method: The MIDA model of the IT’IS Foundation, Switzerland, comprises 115 high-resolution tissue models in the form that the BEM-FMM toolkit is modified to accept. The updated BEM-FMM toolkit is tested using this head model.Results: The BEM-FMM toolkit has been successfully modified to accept head models consisting of one unique mesh per unique tissue while still supporting its initial model format of one unique mesh per boundary between two specific tissues. Performance impacts occur in the preprocessing phase only, meaning that the charge computation method performs equally well regardless of model format.

AbstractEver since international large-scale student assessments made it possible to rank countries according to their equitability, Nordic countries have topped these rankings. Nevertheless, a decline in equity has been reported lately. However, the process of empirical enquiry that leads to specific inferences on equity partly stays obscure to education decision-makers. This unawareness of the boundaries of specific methodological and analytical approaches may lead to wrong interpretations and policy implications. Therefore, our aim is to discuss and empirically illustrate how the array of choices taken throughout the research process, from equity conceptualization and operationalization to its measurement, may affect the inferences on educational equity for Nordic countries. Our sample includes fourth- and eighth-grade students from Norway, Sweden, Denmark and Finland who participated in TIMSS 2015. We applied two-level multigroup regression models within the structural equation modelling framework to investigate the sensitivity of the countries’ level of equity to: (a) operationalization of the socioeconomic status measure; (b) operationalization of equity or, in other words, the method of analysis employed (e.g., bivariate analysis versus univariate); (c) single-level against multilevel analytical approaches; (d) the grade/age of students; and (e) the choice of the learning outcome across subject domains. Prior to the analyses, we estimated the comparability of SES as a latent construct between Nordic countries. Our results confirmed that some of the most common choices to measure educational equity do matter. Thus, we would encourage a researcher to report elaborately on the research process and inform on its limitations because if interpreted wrongly, it may have unfavourable consequences for a particular group of individuals.

Full textAbstract:
The pathomechanics of knee anterior cruciate ligament (ACL) injury related to the female athlete is of high interest due to the high incidence of injury compared to males participating in the same sport. The mechanisms of ACL injury are still not completely understood, but it is known that single-leg landings, stopping and cutting at high velocity are some of the non-contact mechanisms that are causing these injuries. This study analyzed a subject specific analysis of a single-leg drop landing that was performed by a female subject at 60%, 80% and 100% of her maximum vertical jump. The femur, tibia, articular cartilage, and menisci were modeled as 3-D structures and the data collected from the motion analysis was used to obtain the knee joint contact stresses in finite element analysis (FEA). The four major ligaments of the knee were modeled as non-linear springs. Material properties of previously published studies were used to define the soft tissue structures. The articular cartilage was defined as isotropic elastic and the menisci were defined as transverse isotropic elastic. Two different styles of single-leg landings were compared to one another, resembling landing from a basketball rebound. The first landing style, single-leg arms up (SLAU), produced larger knee flexion angles at peak ground reaction forces, while single-leg arms across (SLAX) landings produced higher peak vertical ground reaction forces along with lower knee flexion angles. The mean peak vertical ground reaction force was 2.9–3.5 bodyweight for SLAU landings, while they were 3.0–3.8 for SLAX landings. The time to peak vertical ground reaction force with SLAU landings were 69 ms (60%), 60 ms (80%), and 55 ms (100%); SLAX landings were 61 ms (60%), 61 ms (80%), and 51 ms (100%).

Abstract A model to study the stability of the spent fuel under repository conditions has been developed. The fuel-water interface is a dynamic redox system, where oxidising conditions due to the radiolysis of water can lead to the release of the uranium and the radionuclides embedded in the fuel matrix. Both kinetic and thermodynamic processes have been taken into account. Special attention is given to the unit rate of matrix oxidation/dissolution, which has been the subject of a specific radiolytic model. The findings of this work have important implications for the applicability of solubility limits in establishing source term models.

Full textAbstract:
Simplified analytical approaches to estimate hip joint contact pressures using perfectly spherical geometry have been described in the literature (rigid body spring models); however, estimations based on these simulations have not corresponded well with experimental in vitro data. Recent evidence from our laboratory suggests that finite element (FE) models of the hip joint that incorporate detailed geometry for cartilage and bone can predict cartilage pressures in good agreement with experimental data [1]. However, it is unknown whether this degree of model complexity is necessary. The objective of this study was to compare cartilage contact pressure predictions from FE models with varying degrees of simplicity to elucidate which aspects of hip morphology are required to obtain accurate predictions of cartilage contact pressure. Models based on 1) subject-specific (SS) geometry, 2) spheres, and 3) rotational conchoids were analyzed.

McGarrigle, M. Embedding Building Information Modelling into Construction Technology and Documentation Courses. Unitec ePress, November 2014. http://dx.doi.org/10.34074/rsrp.005.
Full textAbstract:
The aim of this research is to generate a resource to assist construction lecturers in identifying opportunities where Building Information Modelling [BIM] could be employed to augment the delivery of subject content within individual courses on construction technology programmes. The methodology involved a detailed analysis of the learning objectives and underpinning knowledge of the course content by topic area, within the residential Construction Systems 1 course presently delivered at Unitec on the National Diplomas in Architectural Technology[NDAT], Construction Management [NDCM] and Quantity Surveying [NDQS]. The objective is to aid students’ understanding of specific aspects such as planning controls or sub-floor framing by using BIM models, and investigate how these could enhance delivery modes using image,animation and interactive student activity. A framework maps the BIM teaching opportunities against each topic area highlighting where these could be embedded into construction course delivery. This template also records software options and could be used in similar analyses of other courses within similar programmes to assist with embedding BIM in subject delivery.

Blundell, S. Tutorial : the DEM Breakline and Differencing Analysis Tool—step-by-step workflows and procedures for effective gridded DEM analysis. Engineer Research and Development Center (U.S.), November 2022. http://dx.doi.org/10.21079/11681/46085.
Full textAbstract:
The DEM Breakline and Differencing Analysis Tool is the result of a multi-year research effort in the analysis of digital elevation models (DEMs) and the extraction of features associated with breaklines identified on the DEM by numerical analysis. Developed in the ENVI/IDL image processing application, the tool is designed to serve as an aid to research in the investigation of DEMs by taking advantage of local variation in the height. A set of specific workflow exercises is described as applied to a diverse set of four sample DEMs. These workflows instruct the user in applying the tool to extract and analyze features associated with terrain, vegetative canopy, and built structures. Optimal processing parameter choices, subject to user modification, are provided along with sufficient explanation to train the user in elevation model analysis through the creation of customized output overlays.

Sandford, Robert, Vladimir Smakhtin, Colin Mayfield, Hamid Mehmood, John Pomeroy, Chris Debeer, Phani Adapa, et al. Canada in the Global Water World: Analysis of Capabilities. United Nations University Institute for Water, Environment and Health, November 2018. http://dx.doi.org/10.53328/vsgg2030.
Full textAbstract:
This report critically examines, for the first time, the capacity of Canada’s water sector with respect to meeting and helping other countries meet the water-related targets of the UN’s global sustainable development agenda. Several components of this capacity are examined, including water education and research, investment in water projects that Canada makes internally and externally, and experiences in water technology and governance. Analysis of the water education system suggests that there is a broad capability in institutions of higher learning in Canada to offer training in the diverse subject areas important in water. In most cases, however, this has not led to the establishment of specific water study programmes. Only a few universities provide integrated water education. There is a need for a comprehensive listing of water-related educational activities in universities and colleges — a useful resource for potential students and employers. A review of recent Canadian water research directions and highlights reveals strong and diverse water research capacity and placed the country among global leaders in this field. Canada appears to be within the top 10 countries in terms of water research productivity (publications) and research impact (citations). Research capacity has been traditionally strong in the restoration and protection of the lakes, prediction of changes in climate, water and cryosphere (areas where water is in solid forms such as ice and snow), prediction and management of floods and droughts. There is also a range of other strong water research directions. Canada is not among the top 10 global water aid donors in absolute dollar numbers; the forerunners are, as a rule, the countries with higher GDP per capita. Canadian investments in Africa water development were consistently higher over the years than investments in other regions of the global South. The contributions dropped significantly in recent years overall, also with a decline in aid flow to Africa. Given government support for the right business model and access to resources, there is significant capacity within the Canadian water sector to deliver water technology projects with effective sustainable outcomes for the developing world. The report recommends several potential avenues to elevate Canada’s role on the global water stage, i.e. innovative, diverse and specific approaches such as developing a national inventory of available water professional capacity, and ranking Universities on the strength of their water programmes coordinating national contributions to global sustainability processes around the largest ever university-led water research programme in the world – the 7-year Global Water Futures program targeting specific developmental or regional challenges through overseas development aid to achieve quick wins that may require only modest investments resolving such chronic internal water challenges as water supply and sanitation of First Nations, and illustrating how this can be achieved within a limited period with good will strengthening and expanding links with UN-Water and other UN organisations involved in global water policy work To improve water management at home, and to promote water Canadian competence abroad, the diverse efforts of the country’s water sector need better coordination. There is a significant role for government at all levels, but especially federally, in this process.

Chornodon, Myroslava. FEAUTURES OF GENDER IN MODERN MASS MEDIA. Ivan Franko National University of Lviv, February 2021. http://dx.doi.org/10.30970/vjo.2021.49.11064.
Full textAbstract:
The article clarifies of gender identity stereotypes in modern media. The main gender stereotypes covered in modern mass media are analyzed and refuted. The model of gender relations in the media is reflected mainly in the stereotypical images of men and woman. The features of the use of gender concepts in modern periodicals for women and men were determined. The most frequently used derivatives of these macroconcepts were identified and analyzed in detail. It has been found that publications for women and men are full of various gender concepts that are used in different contexts. Ingeneral, theanalysisofthe concept-maximums and concept-minimum gender and their characteristics is carried out in the context of gender stereotypes that have been forme dand function in the society, system atizing the a ctual presentations. The study of the gender concept is relevant because it reveals new trends and features of modern gender images. Taking into account the special features of gender-labeled periodicals in general and the practical absence of comprehensive scientific studies of the gender concept in particular, there is a need to supplement Ukrainian science with this topic. Gender psychology, which is served by methods of various sciences, primarily sociological, pedagogical, linguistic, psychological, socio-psychological. Let us pay attention to linguistic and psycholinguistic methods in gender studies. Linguistic methods complement intelligence research tasks, associated with speech, word and text. Psycholinguistic methods used in gender psychology (semantic differential, semantic integral, semantic analysis of words and texts), aimed at studying speech messages, specific mechanisms of origin and perception, functions of speech activity in society, studying the relationship between speech messages and gender properties participants in the communication, to analyze the linguistic development in connection with the general development of the individual. Nowhere in gender practice there is the whole arsenal of psychological methods that allow you to explore psychological peculiarities of a person like observation, experiments, questionnaires, interviews, testing, modeling, etc. The methods of psychological self-diagnostics include: the gender aspect of the own socio-psychological portrait, a gender biography as a variant of the biographical method, aimed at the reconstruction of individual social experience. In the process of writing a gender autobiography, a person can understand the characteristics of his gender identity, as well as ways and means of their formation. Socio-psychological methods of studying gender include the study of socially constructed women’s and men’s roles, relationships and identities, sexual characteristics, psychological characteristics, etc. The use of gender indicators and gender approaches as a means of socio-psychological and sociological analysis broadens the subject boundaries of these disciplines and makes them the subject of study within these disciplines. And also, in the article a combination of concrete-historical, structural-typological, system-functional methods is implemented. Descriptive and comparative methods, method of typology, modeling are used. Also used is a method of content analysis for the study of gender content of modern gender-stamped journals. It was he who allowed quantitatively to identify and explore the features of the gender concept in the pages of periodicals for women and men. A combination of historical, structural-typological, system-functional methods is also implemented in the article. Descriptive and comparative methods, method of typology, modeling are used. A method of content analysis for the study of gender content of modern gender-labeled journals is also used. It allowed to identify and explore the features of the gender concept quantitatively in the periodicals for women and men. The conceptual perception and interpretation of the gender concept «woman», which is highlighted in the modern gender-labeled press in Ukraine, requires the elaboration of the polyfunctionality of gender interpretations, the comprehension of the metaphorical perception of this image and its role and purpose in society. A gendered approach to researching the gender content of contemporary periodicals for women and men. Conceptual analysis of contemporary gender-stamped publications within the gender conceptual sphere allows to identify and correlate the meta-gender and gender concepts that appear in society.
