description: Der Umgang mit Heterogenität im inklusiven Mathematikunterricht erfordert von Lehrkräften spezifische Kompetenzen (z. B. Bertram, 2022; Scherer, 2022), auf die bereits die Lehrkräfteausbildung vorbereiten sollte. Verschiedene Forschungsprojekte haben sich mit der Entwicklung und Evaluation entsprechender Lehrkonzepte befasst und dabei neben der Bedeutung professionellen Wissens bzw. Handlungspotenzialen auch einen Fokus auf die Überzeugungen und Einstellungen (angehender) Lehrkräfte gelegt (z. B. Häsel-Weide, 2017; Scharenberg & Opalinski, 2019; Scherer 2022). Einstellungen zum inklusiven Unterricht sind insbesondere relevant, weil sie mit einer erfolgreichen Umsetzung von Inklusion sowie mit wichtigen Praktiken im inklusiven Unterricht in Verbindung gebracht werden (vgl. Avramidis & Norwich, 2002; Forlin et al., 2011; Ruberg & Porsch, 2017). Im vorliegenden Beitrag werden daher Einstellungen von Lehramtsstudierenden zu inklusivem Mathematikunterricht fokussiert.
Developing Advanced Approaches to Deliver Value on Construction Projects: Integrating Social Dynamics, Digital Modelling Techniques, and Lean Concepts
Creators: Khalife, Salam
Publisher: name: University of Alberta Library
Year: 2023

Construction projects are complex endeavors that involve multiple stakeholders, challenging processes, and diverse objectives. The effective management and alignment of project value propositions are crucial for ensuring successful outcomes and satisfying the needs and expectations of stakeholders. Value Management practices have offered ways to support the identification and generation of project value. However, conflicting and unclear requirements among stakeholders hinder a shared understanding of project value leading to issues such as varied work practices, rework, low productivity, and increased costs. Moreover, the lack of reliable tools and methods to track value attainment during design development undermines the effectiveness of value management workshops usually conducted in early phases. Additionally, insufficient attention is given to studying the impact of social dynamics on the delivery of value on projects. Accordingly, this research aims to improve project value delivery and value management practices by rethinking value identification and planning methods, and by proposing a digital simulation tool with metrics to track and control value throughout project phases. Specifically, the study recognizes the significance of social dynamics such as interactions, relationships, and behaviors of individuals and groups, in shaping project outcomes. The research recognizes the transformative potential of digital methods and lean principles in enhancing value management practices. Accordingly, three major modules are outlined: (1) mapping factors influencing value delivery, recommending value identification strategies, and proposing a simple-warning dashboard for detecting value conflicts, (2) developing a socio-technical framework to track value attainment and evaluate design communication and team structures using social network analysis and lean practices, and (3) deploying simulation as a value management tool using agent-based modelling techniques to monitor value alignment and fulfillment throughout the project design. In addition to the mentioned modules, a portion of this research was dedicated to investigating architecture and engineering education with respect to teaching value and proposing essential practices to overcome the identified shortcomings. The overall objective of this research is to create value in the built environment for everyone by advancing both industry practices and educational systems toward a more human-centric design and management. By prioritizing human and social capital, while ensuring alignment with the diverse needs and requirements of all stakeholders, the identification, tracking, and management of social, cultural, and environmental value using digital tools contribute to equitable satisfaction and well-being of all entities engaged in construction projects

description: We explore chiral symmetry breaking in a magnetic field within a Nambu-Jona-Lasinio model of interacting massless quarks including tensor channels. We show that the new interaction channels open up via Fierz identities due to the explicit breaking of the rotational symmetry by the magnetic field. We demonstrate that the magnetic catalysis of chiral symmetry breaking leads to the generation of two independent condensates, the conventional chiral condensate and a spin-one condensate. While the chiral condensate generates a dynamical fermion mass, the new condensate gives rise to a dynamical anomalous magnetic moment for the fermions. As a consequence, the spectrum of the excitations in all Landau levels, except the lowest one, exhibits Zeeman splitting. Since the pair, formed by a quark and an antiquark with opposite spins, possesses a resultant magnetic moment, an external magnetic field can align it giving rise to a net magnetic moment for the ground state. This is the physical interpretation of the spin-one condensate. Our results show that the magnetically catalyzed ground state in QCD is actually richer than previously thought. The two condensates contribute to the effective mass of the LLL quasiparticles in such a way that the critical temperature for chiral symmetry restoration becomes enhanced.

description: In the exploration of viable models of dynamical electroweak symmetry breaking, it is essential to locate the lower end of the conformal window and know the mass anomalous dimensions there for a variety of gauge theories. We calculate, with the Schrödinger functional scheme, the running coupling constant and the mass anomalous dimension of SU(2) gauge theory with six massless Dirac fermions in the fundamental representation. The calculations are performed on $6^4$ - $24^4$ lattices over a wide range of lattice bare couplings to take the continuum limit. The discretization errors for both quantities are removed perturbatively. We find that the running slows down and comes to a stop at $0.06 \lesssim 1/g^2 \lesssim 0.15$ where the mass anomalous dimension is estimated to be $0.26 \lesssim γ^*_m \lesssim 0.74$.

description: Use of High Performance Computing (HPC) resources remains an accessibility issue for the majority of lab-based researchers with data driven pipelines. Many lab-based researchers lack an intensive computational background and depend on HPC experts or support from external resources. This translates into either a slowdown of research as lab personnel spend more time on effectively using HPC clusters, programming, scripting and debugging or inflating the research cost by hiring or outsourcing this job. In this work we present
 a one click Gateway solution to aid scientists and researchers from non computer engineering backgrounds to reduce the iterative and "technical" steps involved in data driven pipelines by setting up of workflows via use of Open OnDemand’s custom passenger apps. We demonstrate this solution by creating a data processing pipeline to automate data transfer, archival, and initial processing steps for a genomics core tasked with generating Terabytes of data weekly. Moreover, these apps can be shared and deployed on any instance of
 Open OnDemand with zero prerequisite and installation step.

description: Für den Stochastikunterricht stehen eine Reihe von Visualisierungen zur Verfügung, um Situationen mit zwei dichotomen Merkmalen (z. B. Merkmal 1: Gesundheitsstatus mit den Ausprägungen krank vs. gesund; Merkmal 2: Testergebnis mit den Ausprägungen Test positiv vs. Test negativ) zu illustrieren: Baumdiagramme, Vierfeldertafeln, Einheitsquadrate, Doppelbäume, Netzdiagramme und viele mehr. Schulisch werden vor allem Vierfeldertafeln mit absoluten oder relativen Häufigkeiten (bzw. Wahrscheinlichkeiten) und Baumdiagramme mit relativen Häufigkeiten an den Ästen eingesetzt. Da Knoten-Ast-Strukturen wie Baumdiagramme das Potential besitzen, sowohl absolute Häufigkeiten in den Knoten (vgl. Abb. 1) als auch relative Häufigkeiten an den entsprechenden Ästen darzustellen, stehen Baumdiagramme sowie die erweiterten Knoten-Ast-Strukturen Doppelbaum (Wassner, 2004) und Netzdiagramm (Binder et al., 2020; Binder et al., in review) im Fokus des vorliegenden Beitrags. Diese Verbindungsmöglichkeit der beiden Repräsentationen ist entscheidend, weil es einerseits die Aufgabe von Mathematiklehrkräften ist, das Wahrscheinlichkeitskalkül zu vermitteln und andererseits ein Verständnis von Wahrscheinlichkeiten durch die Präsentation von absoluten Häufigkeiten unterstützt werden kann (Gigerenzer & Hoffrage, 1995; Binder et al., 2015). Überdies können Knoten-Ast-Strukturen „curricular mitwachsen“, indem mit entsprechenden Visualisierungen gearbeitet wird, die zunächst nur absolute Häufigkeiten in den Knoten enthalten, in der Sekundarstufe I können dann relative Häufigkeiten an den Ästen ergänzt werden und in höheren Klassen schließlich auch entsprechende Wahrscheinlichkeiten.
Geostatistical Modeling for Grade Control and Long Range Models
Creators: Amihere, Norris
Publisher: name: University of Alberta Library
Year: 2023

In general, less than one billionth of the volume of a deposit is sampled before production decisions. The grades and other rock properties are estimated in the unsampled volume. The success of a mine is dependent on accurate grade control. The grade control process establishes the final planned destination of mined material, directly influencing the operation’s profitability. Mistakes at this stage are costly and irreversible. Resource models are considered long-term when used for

long-term mine planning; an example is a Life of Mine (LOM) plan. Long-term models are based on widely-spaced drilling, which is gradually filled in as the project advances. Long-term models provide estimates of tonnage and grade for each period involved through to the end of the life of the

mine. Long-term models are designed to estimate what will be achieved during grade control with acceptable accuracy.

Geostatistical modeling is challenging because of the geological variability/uncertainty in the grades. For example, when material needs to be directed to various stockpiles or treatment facilities, the procedure is frequently complicated by the need for numerous classifications. Grade control programs aim to minimize the misclassification of material, while the primary focus of long-term models is on the accuracy of estimated recoverable resources awaiting more data at the time of grade control. The prediction goals differ for grade control and long-term modeling; therefore, the appropriate

geostatistical techniques and parameter setups differ. For this research, geostatistical models are generated through the following techniques: (1) Ordinary Kriging, (2) Expected sequential Gaussian Simulation, (3) Localized Uniform Conditioning, and (4) Localized Sequential Gaussian Simulation. The expected profits from realizations are demonstrated with a series of examples. The appropriate

modeling techniques and parameter setups for grade control and long-term models in the presence

of geological uncertainty are demonstrated and evaluated.

description: We extend the orbital-dependent electron tunneling model implemented within the three-dimensional (3D) Wentzel-Kramers-Brillouin (WKB) atom-superposition approach to simulate spin-polarized scanning tunneling microscopy (SP-STM) above magnetic surfaces. The tunneling model is based on the electronic structure data of the magnetic tip and surface obtained from first principles. Applying our method, we analyze the orbital contributions to the tunneling current, and study the nature of atomic contrast reversals occurring on constant-current SP-STM images above the Fe(110) surface. We find an interplay of orbital-dependent tunneling and spin-polarization effects responsible for the contrast inversion, and we discuss its dependence on the bias voltage, on the tip-sample distance, and on the tip orbital composition.

Obschon in den vergangenen zwei Jahren der Pandemie sicherlich viele Impulse aus Forschung und Praxis zur Entwicklung, Erforschung und Erprobung digitaler Lernangebote erwachsen sind, so „wurde es in Deutschland verpasst, fachdidaktisch hochwertige digitale Unterrichtsmaterialien rechtzeitig zu entwickeln, so dass die Schulen nun darauf zugreifen können. […] Der (durch die Schulschließungen verstärkte) Digitalisierungsschub hat im Mathematikunterricht an vielen Schulen […] leider zu einem Verlust an fachdidaktischer Qualität geführt, nicht zu einer Steigerung“ (Prediger, 2021). Darüber hinaus adressiert das derzeitige Angebot fachdidaktischer Software vornehmlich formal-unstrukturierte Übungsformen und weniger die Konzeptentwicklung (Walter, i. Dr.). Das Minisymposium „Lernen, Lehren und Forschen mit digitalen Medien im Mathematikunterricht der Primarstufe“ ist Ort der Diskussion genau solcher Entwicklungs- und Forschungsarbeiten, die unter dem Primat der Fachdidaktik analysiert werden.
Drill-hole Spacing Optimizations in Grade-Control
Creators: Gomes, Caio
Publisher: name: University of Alberta Library
Year: 2023

Final estimates at the grade-control (GC) stage of mining are built to maximize the correct classificationof mineable blocks. The costs include drilling, mining, and processing. When consideringdedicated GC drilling, Drill-hole spacing (DHS) optimization for profit balances the cost of estimationuncertainty and the cost of the drilling. The drilling amount is optimal when drilling less wouldincur large estimation costs and drilling more would incur large drilling costs.To support DHS optimization in GC, a DHS framework for regularly-spaced drill-holes is developedand evaluated. Aiming at increasing profit and going beyond regularly-spaced drilling, a secondDHS methodology is designed, where DHS from two phases are optimized. An automated workflowis developed that delivers the location of the final optimal GC samples in addition to optimal DHSdecisions.The methodology of DHS optimization for profit is investigated by considering geology, miningselectivity, spatial continuity, ore price, and other factors. Each factor is varied one at a time,and optimal DHS decisions and profit changes are recorded and summarized. Finally, the DHSframeworks are demonstrated on real data from a copper-molybdenum deposit.The research establishes a conceptual foundation and practical details for developing DHS optimizationfor final estimates in mining operations with dedicated drilling systems. The nested DHSframework can lead to improved results, but greater flexibility at the time of mining is required.

description: Die Erarbeitung der Multiplikation in der zweiten Klasse beruht noch immer häufig auf dem Auswendiglernen nicht verbundener Einmaleinsreihen. Das Denken in gleich großen Einheiten bzw. Bündeln (unitizing nach Lamon,1994) als zentrale multiplikative Verstehensgrundlage wird dabei allerdings nicht zugrunde gelegt. Damit ist die Fähigkeit gemeint in gebündelten Einheiten flexibel denken und somit diese Einheiten flexibel in ihrer Anzahl und Größe verändern zu können (Lamon, 1994; Siemon, 2019; Steffe, 1994). Dies impliziert gleichermaßen, dass die Kinder Einsichten in die differentielle Unterscheidung von Multiplikator und Multiplikand erlangen. Fehlt diese Verstehensgrundlage wird das Weiterlernen in der Sekundarstufe nachweislich erschwert (Siemon, 2019). Die App 1·1tool setzt genau hier an und unterstützt die Lehrkraft im Unterricht beim Prozess eines ganzheitlichen Einmaleinslehrens. Auf welche Weise diese Unterstützung stattfinden kann, soll in diesem Beitrag anhand von zwei ausgewählten Szenen illustriert werden.

description: The presence of two compatible Hamiltonian structures is known to be one of the main, and the most natural, mechanisms of integrability. For every pair of Hamiltonian structures, there are associated conservation laws (first integrals). Another approach is to consider the second Hamiltonian structure on its own as a tensor conservation law. The latter is more intrinsic as compared to scalar conservation laws derived from it and, as a rule, it is "simpler". Thus it is natural to ask: can the dynamics of a bi-Hamiltonian system be understood by studying its Hamiltonian pair, without studying the associated first integrals?\par In this paper, the problem of stability of equilibria in bi-Hamiltonian systems is considered and it is shown that the conditions for nonlinear stability can be expressed in algebraic terms of linearization of the underlying Poisson pencil. This is used to study stability of stationary rotations of a free multidimensional rigid body.

description: Twisted compactification of the 6d N=(2,0) theories on a punctured Riemann surface give a large class of 4d N=1 and N=2 gauge theories, called class S. We argue that nonperturbative dynamics of class S theories are described by 5d maximal Super-Yang-Mills (SYM) twisted on the Riemann surface. In a sense, twisted 5d SYM might be regarded as a "Lagrangian" for class S theories on R^{1,2} times S^1. First, we show that twisted 5d SYM gives generalized Hitchin's equations which was proposed recently. Then, we discuss how to identify chiral operators with quantities in twisted 5d SYM. Mesons, or holomorphic moment maps, are identified with operators at punctures which are realized as 3d superconformal theories T_rho[G] coupled to twisted 5d SYM. "Baryons" are identified qualitatively through a study of 4d N=2 Higgs branches. We also derive a simple formula for dynamical superpotential vev which is relevant for BPS domain wall tensions. With these tools, we examine many examples of 4d N=1 theories with several phases such as confining, Higgs, and Coulomb phases, and show perfect agreements between field theories and twisted 5d SYM. Spectral curve is an essential tool to solve generalized Hitchin's equations, and our results clarify the physical information encoded in the curve.

description: We consider a set of macroscopic (classical) degrees of freedom coupled to an arbitrary many-particle Hamiltonian system, quantum or classical. These degrees of freedom can represent positions of objects in space, their angles, shape distortions, magnetization, currents and so on. Expanding their dynamics near the adiabatic limit we find the emergent Newton's second law (force is equal to the mass times acceleration) with an extra dissipative term. In systems with broken time reversal symmetry there is an additional Coriolis type force proportional to the Berry curvature. We give the microscopic definition of the mass tensor relating it to the non-equal time correlation functions in equilibrium or alternatively expressing it through dressing by virtual excitations in the system. In the classical (high-temperature) limit the mass tensor is given by the product of the inverse temperature and the Fubini-Study metric tensor determining the natural distance between the eigenstates of the Hamiltonian. For free particles this result reduces to the conventional definition of mass. This finding shows that any mass, at least in the classical limit, emerges from the distortions of the Hilbert space highlighting deep connections between any motion (not necessarily in space) and geometry. We illustrate our findings with four simple examples.

description: This paper proposes a variational approach to describe the evolution of organization of complex systems from first principles, as increased efficiency of physical action. Most simply stated, physical action is the product of the energy and time necessary for motion. When complex systems are modeled as flow networks, this efficiency is defined as a decrease of action for one element to cross between two nodes, or endpoints of motion - a principle of least unit action. We find a connection with another principle that of most total action, or a tendency for increase of the total action of a system. This increase provides more energy and time for minimization of the constraints to motion in order to decrease unit action, and therefore to increase organization. Also, with the decrease of unit action in a system, its capacity for total amount of action increases. We present a model of positive feedback between action efficiency and the total amount of action in a complex system, based on a system of ordinary differential equations, which leads to an exponential growth with time of each and a power law relation between the two. We present an agreement of our model with data for core processing units of computers. This approach can help to describe, measure, manage, design and predict future behavior of complex systems to achieve the highest rates of self-organization and robustness.

Undergraduate Students’ Perspectives of Disability Within an International Community Service-Learning Program
Creators: Craig, Heather
Publisher: name: University of Alberta Library
Year: 2023

The way people with impairments are perceived and how disability is understood is important to

explore due to their ongoing marginalization and oppression in our world. This study captured

undergraduate students’ perspectives of disability before, during, and after participating in an

international community service-learning (CSL) setting. The views of 13 past Play Around the

World (PAW) participants aged 24 to 37 at the time of this study, were explored through

interpretive description using semi-structured interviews. The primary themes from the thematic

data analysis included: preparation, hands-on learning, and change (or not). Participants found

that preparation including engagement and experience with people with impairments was critical

for them to gain confidence leading play activities for and with them. Additionally, participants

found success leading play through hands-on learning and when they perceived the children as

kids rather than focusing on impairment. Lastly, the students' mindsets and attitudes played a

large role in how much their worldviews expanded throughout the service-learning experience

and whether they experienced change or not. Students’ mindsets ultimately determined how

successfully they moved from discomfort to comfort, learning, growth, and understanding when

working with people experiencing disability in their CSL placements. Recommendations for

future CSL preparation include: Allowing time for relationships and trust to develop organically

between the PAW students and local partners and children, facilitating supervised/supported

engagement with children with impairments before traveling overseas and ensuring that the

experiences meet communities needs.

AI Assisted Mole Detection for Online Dermatology Triage in Telemedicine Settings

Skin moles are one of the most commonly occurring dermatological conditions prevalent nowadays. Early identification and diagnosis of moles are absolutely crucial since they often turn out to be precursors to serious conditions such as melanoma, a dangerous type of skin cancer. Therefore, to ensure an efficient treatment of cases based on their severity, they need to be assessed systematically. In this thesis, we present an artificial intelligence (AI )enabled triage tool to identify moles from images uploaded by patients to a teledermatology platform. The proposed approach employs NesT, one of the latest state-of-the-art transformer-based network for classification. Our system acts as a filter by sending a warning flag if a mole is detected. This can be used to help dermatologists set up consultation appointments in a physical setting by giving priority if the patient has a mole on their image.

A comparative study of the prediction performance of the different neural network models has been provided for different performance metrics of interest. The results presented in this thesis have been obtained from two sets of data, consisting of more than 26,000 clinical pictures with combined different dermatological conditions. Multiple experiments using different models yielded a macro-average recall value as high as 0.955, along with overall accuracy and macro-average precision values of 0.962 and 0.958, respectively.
In the Battle for Hearts and Minds: Music in the Construction and Deconstruction of Boko Haram’s Ideologies in Northern Nigeria

This dissertation examines the functionality of Boko Haram’s Islamic nashid in its propaganda videos to promote its radical ideologies that reject the secularity of the Nigerian state, its constitution, and Westernization promoted through education and to establish an Islamic state rule in strict compliance with the tawhid. In particular, I interrogate the uses of this musical tradition to support extremism as one of the vehicles associated with the creation of this group’s proposed Nigerian Islamic State, the rejection of Western education, and the institution of compulsory Qurʾanic education and Shari‘a  law – a religious system of justice built on the Qurʾan and Hadith. I also examine the use of nashid and popular songs composed and performed by Muslim and Christian musicians to counter the ideologies which BH promotes. The research investigates nashid and songs in offline (cassette) and online (YouTube/Facebook), tracing their origin and development and their application to Islamic reformist movements, with a focus on Uthman dan Fodio (Sunni) and Ibrahim El Zakzaky (b. 1953) – the leader of the Shiʿa Islamic Movement of Nigeria. This historical and contemporary study aims to understand if BH nashid is privileged in the existing local cultural production adopted from external sources within the global jihad network (struggle). Understanding nashid’s historical and global background will provide a basis for analyzing local lyrics composed in Hausa and Kanuri and investigating how local musicians use their songs to counter BH’s radical creed. This study adopted the ethnographic method that involves interviews with informants (musicians, clerics, military personnel, and members of the society) knowledgeable about BH’s activities and vocal in producing songs that criticize its reign of terror in the North. This study argues the justification of violence by BH against those they believed to be unbelievers, and taghut birthed songs that criticize them from two perspectives: the Christians who believe BH’s terror against them was to prevent the gospel’s spread and the Muslims who believe BH is misinterpreting scripture to drive its radical creeds. I further argue that as long as these crises last, anti and pro-BH songs will be weaponized in the battle of the minds and souls of Muslims and Christians.

description: Plant parasitic nematodes are important phytopathogens, they harm the growth of agricultural and forestry plants for a long time. Scientists have done a series of studies on them to prevent and solve the diseases that they cause. With the advent of the genomics era, genome sequencing of plant parasitic nematodes has been greatly accelerated, and a large amount of data has been generated. This study developed the Plant Parasitic Nematodes Database (http://nematode.org.cn/), a platform to bring all these data together. The PPND contains genomic, transcriptomic, protein, and functional annotation data. It allows users to conduct BLAST searches, genome browser analyses, and download bioinformatics data for deeper research. PPND will be continuously updated, and new data will be integrated. We hope that the PPND will become a comprehensive genomic data platform for plant parasitic nematode research.

description: We employ scaling arguments and optimal fluctuation theory to establish a general relation between quantum Griffiths singularities and the Harris criterion for quantum phase transitions in disordered systems. If a clean critical point violates the Harris criterion, it is destabilized by weak disorder. At the same time, the Griffiths dynamical exponent $z'$ diverges upon approaching the transition, suggesting unconventional critical behavior. In contrast, if the Harris criterion is fulfilled, power-law Griffiths singularities can coexist with clean critical behavior but $z'$ saturates at a finite value. We present applications of our theory to a variety of systems including quantum spin chains, classical reaction-diffusion systems and metallic magnets; and we discuss modifications for transitions above the upper critical dimension. Based on these results we propose a unified classification of phase transitions in disordered systems.

Timing, Carrier, and Frame Synchronization of Burst-Mode CPM
Creators: name: Hosseini, Ehsan

Year: 2013
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this paper, we propose a complete synchronization algorithm for continuous phase modulation (CPM) signals in burst-mode transmission over additive white Gaussian noise (AWGN) channels. The timing and carrier recovery are performed through a data-aided (DA) maximum likelihood algorithm, which jointly estimates symbol timing, carrier phase, and frequency offsets based on an optimized synchronization preamble. Our algorithm estimates the frequency offset via a one dimensional grid search, after which symbol timing and carrier phase are computed via simple closed-form expressions. The mean-square error (MSE) of the algorithm's estimates reveals that it performs very close to the theoretical Cramér-Rao bound (CRB) for various CPMs at signal-to-noise ratios (SNRs) as low as 0 dB. Furthermore, we present a frame synchronization algorithm that detects the arrival of bursts and estimates the start-of-signal. We simulate the performance of the frame synchronization algorithm along with the timing and carrier recovery algorithm. The bit error rate results demonstrate near ideal synchronization performance for low SNRs and short preambles.
