Intron Recognition at the 3' Splice Site by U2AF, SF1 and p14
Creators: Grewal, Charnpal
Publisher: name: University of Alberta Library
Year: 2023

The discontinuous split-gene structure is a core feature of eukaryotic gene architecture and requires pre-mRNA splicing to remove silent intron sequences from the initial pre-mRNA transcript before it becomes a mature mRNA suitable for protein synthesis. Splicing begins with recognition of both the 5′ and 3′ SS (splice site) of the intron, and the 3′ SS is recognized by the heterotrimeric U2AF/SF1 protein complex.

Here, U2AF dimer and U2AF/SF1 trimer variants were expressed from the fission yeast, Schizosaccharomyces pombe. SEC-MALLS and spectroscopy established that the free and RNA-bound complexes are stable, soluble, and monodisperse. This was followed by EMSAs (electrophoretic mobility shift assays) revealing that broadly, SF1 has a major role in binding the 3′ SS and modulates sequence specificity and affinity of the U2AF/SF1 complex for the 3′ SS. Structural characterization via SAXS revealed that U2AF dimer and U2AF/SF1 trimer are well folded and roughly globular in both free and RNA-bound states. This was followed by SEC-SAXS combined with rigid body modelling on a chimeric U2AF/SF1 trimer containing both human and S. pombe components, revealing that U2AF/SF1 is conformationally flexible in solution and favours a more compact, globular form upon binding a 3′ SS RNA.

In addition to the U2AF/SF1 studies, X-ray structures of the S. pombe and Candida albicans p14/SF3B155 complexes were solved revealing that p14 is more conformationally plastic than previously assumed; p14 displaces SF1 during the splicing cycle, therefore these structures contribute to a unified model of 3′ SS recognition.

Ultimately, this thesis is important foundational work for understanding 3′ SS recognition since it is the first published report of the successful expression and purification of the conserved RNA-binding core of the U2AF dimer and U2AF/SF1 trimer complexes.
title: Multi-scale biosurfactant production and biosurfactant=aided soil washing
Creators: name: Hu, Jiheng
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Biosurfactants are widely used in oil and environmental industries due to their unique properties. The thesis first focused on examining tuna fish waste as low-cost substrates for microbial growth through an enzyme hydrolyzation process to produce the biosurfactant, surfactin. After enzyme hydrolyzation, the biosurfactant fermentation experiments were conducted at the bench-scale, batch-scale, and pilot-scale to determine optimal conditions for potential industrial production operations. Tuna fish waste was demonstrated to be a feasible substrate for supporting the growth of Bacillus subtilis (ATCC® 21332™) for biosurfactant synthesis. Optimal parameters for surfactin production (274 mg/L) were determined by conduct of the multi-scale fermentation tests. The thesis also tackled evaluating the potential of biosurfactant-aided soil washing under different temperatures and salinity levels for oil removal. Rhamnolipids biosurfactant and Dioctyl sulfosuccinate sodium salt (DOSS) were mixed at several ratios in shaken flasks to conduct the research. Analysis of the surfactant and crude oil emulsions were developed based on their microscopic images and interfacial tension (IFT). The causal effect of IFT on crude oil removal efficiency was estimated by the structural causal model (SCM). Results of SCM showed that IFT has a minor suppression to the removal efficiency from an overall perspective but can enhance the removal efficiency under the high salinity. The findings of this thesis shed light on biosurfactant production using fish wastes as an economical substrate and biosurfactant-aided soil washing for solving shoreline oil pollution problems. The thesis also demonstrated the applicability of causal inference analysis in environmental engineering.
The Dialectics of Domestication: Domestic Colonialism and Internationalist Criticism in North America
Creators: Kujala, William Jalmer
Publisher: name: University of Alberta Library
Year: 2023

This dissertation offers a reconstruction of the concept of domestic colonialism as developed by revolutionary thinkers in the US 1960s. While rhetorics of occupation and colonial extraction are still prevalent in North American politics, the actual conceptual framework of domestic colonialism is routinely dismissed in the human sciences. I argue that this dismissal largely relies on two readings of the concept that, ultimately, are one-sided: as a social scientific theory of racism, on the one hand, and as a rhetorical strategy, on the other. I argue that ultimately it needs to be considered a concept aimed at dialectical critique, a form of political knowledge aimed at clarifying the stakes and impediments to emancipatory struggles for self-determination in North America. More specifically, it was a rubric of political judgment that pushed against domesticating readings of revolt as containable and answerable within the scope of domestic' politics. It was a dialectical concept in that it worked at the edges of available languages of politics, stretching them to make sense of novel historical predicaments. In turn theorists of domestic colonialism read revolt as exposing the presence of the internationalwithin' the domestic, the impossibility of enclosing domestic' politics as such in North American political orders structured by racial subjugation and colonialism.  I argue that theorists of domestic colonialism offered a signal contribution to the critique of domestic politics as such, re-reading it as in fact a violent but incomplete process of domestication. The domestic colonialism concept, considered as an intervention in the interpretation of insurgency in the 1960s, enacted a de-domestication of political analysis premised on an immanent contradiction between the assumption ofdomestic' politics and the necessarily `international' and imperial forms of power required to maintain it. Therefore examining this concept in context offers an important contribution to critical international political thought through a sustained critique of the conceptual distinction that typically undergird the division of disciplines within political science: that between domestic and international politics.

description: Extrachromosomal circular DNA is a newly evolved hallmark in cancer and is associated with cancer genome instability, oncogene amplification, acquired resistance, and disease progression. A Cancer Circular Genome Atlas (CCGA) consortium is formed to map the missing link of circulome in cancers. Here, we report our pilot CCGA results which we comprehensively characterize the chromosomal DNA, extrachromosomal circular DNA, and transcriptomic alteration landscape in urothelial bladder carcinoma (UBC) of 80 patients by whole-genome/exon sequencing, Circle-seq, single-molecule long-read sequencing technology, and RNA sequencing. Leveraging these large amounts of pair-wise (UBC vs. normal adjacent tissue) and trans-OMICS (genome, circulome, transcriptome) data, we exploit the genome-wide landscape of circular DNA-associated somatic mutations, unbalanced structural variations, oncogene amplification, genomic distributions, structure, and correlations with altered gene expression and clinical outcomes in UBCs. Our results reveal that UBCs contain high load of extrachromosomal circular DNAs which are in cis correlated with cluster of hypermutations (kataegis), copy number variations, oncogene amplifications, structure variations, DNA repair alteration, as well as poor clinical survival. Furthermore, our analyses probe high frequency (81%) of chromothripsis-like events in UBCs, supported by the detection of an extremely chimeric circular DNA containing DNA fragments from nine chromosomes. The CCGA-UBC presents an integrative trans-OMICS analysis strategy to map landscape of extrachromosomal circular DNAs in cancers and may provide opportunities for the development of novel therapeutic strategies.

description: Extreme-mass-ratio inspirals (EMRIs) are promising target sources for space-based interferometers such as LISA, Taiji, and Tianqin. Depending on the astrophysical environment, such as close perturbers or an accretion disk, EMRI orbital evolution may deviate from the predictions of general relativity in vacuum. In particular, we focus on the resonance jumps, i.e., the changes of the conserved quantities induced by a stationary perturbation to the background Kerr geometry. Using Hamiltonian formulation, we provide a closed relation between the jump in Carter constant and that in the axial component of angular momentum. It is also shown that the obtained relation is consistent with the fitting formulae computed for the tidal resonance in previous works.

Development and Evolution of Complex Reproductive Traits in the Brassicaceae and Cleomaceae
Creators: Carey, Shane F
Publisher: name: University of Alberta Library
Year: 2023

Flowering plants exhibit a bewildering diversity of forms, which raises fundamental questions on how that diversity arises. A cornerstone of evolutionary developmental biology is the expansion of comparative landscapes and establishment of focal clades that enable investigation of complex and ecologically important traits. The overarching goal of this thesis is to elucidate the developmental and genetic bases of ecologically important traits in sister families Brassicaceae and Cleomaceae. I analyze developmental and anatomical data, which are key to interpreting gene expression and functional studies. RNA-seq is a powerful tool to examine differential gene expression between and within developmental stages, floral organs, and species. While gene expression data are crucial for exploring the genetics underlying morphologies across taxa, they are only correlational. As such, I established the use of virus-induced gene silencing in Cleomaceae, which provides a causal link between gene function and phenotype. Combined, these approaches are essential for assessing the genetic pathways underlying diversity of form.

Using these approaches, I address a range of questions that answer how changes in gene regulation have led to morphological diversity in Cleomaceae and Brassicaceae. First, I examine how a novel fruit morphology of segmented fruits in two species of Brassicaceae is likely due to modification of an existing fruit-patterning pathway. Second, I demonstrate that there is a high degree of conservation in the genetic basis of nectary formation and nectar secretion between Cleome violacea and model species Arabidopsis thaliana. Next, I show that a key regulator, which has been recruited across the angiosperms for the formation of monosymmetry is also necessary to impart monosymmetry in C. violacea. Finally, I show that differences in floral color between two species of Cleomaceae is due to broad downregulation of the anthocyanin biosynthesis pathway, and modulation of the carotenoid biosynthesis pathway. Thus, my work examines floral and fruit traits in two families. Altogether, my thesis discusses the evolution of symmetry, pigmentation, and nectar gland development in Cleomaceae, and fruit dehiscence/disarticulation in Brassicaceae. In each case, parallel evolution explains much of the observed diversity of form, i.e., across the core eudicots similar gene pathways are responsible for the same traits, such as fruit dehiscence, nectary initiation, monosymmetry, and pigmentation. However, there is also novel gene expression underlying each explored trait, denoting the complex and beautiful nature of fruit and floral evolution.

description: The production of ${\rmΞ}^-$ and ${\rmΩ}^-$ baryons and their anti-particles in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV has been measured using the ALICE detector. The transverse momentum spectra at mid-rapidity ($|y| < 0.5$) for charged $\rmΞ$ and $\rmΩ$ hyperons have been studied in the range $0.6 < p_{\rm T} < 8.0$ GeV/$c$ and $1.2 < p_{\rm T} < 7.0$ GeV/$c$, respectively, and in several centrality intervals (from the most central 0-10% to the most peripheral 60-80% collisions). These spectra have been compared with the predictions of recent hydrodynamic models. In particular, the Krak${ó}$w and EPOS models give a satisfactory description of the data, with the latter covering a wider $p_{\rm T}$ range. Mid-rapidity yields, integrated over $p_{\rm T}$, have been determined. The hyperon-to-pion ratios are similar to those at RHIC: they rise smoothly with centrality up to $\langle N_{\rm part}\rangle$~150 and saturate thereafter. The enhancements (yields per participant nucleon relative to pp collisions) increase both with the strangeness content of the baryon and with centrality, but are less pronounced than at lower energies.

ECI Impacts on Reducing the Causes of Disputes in Construction Projects
Creators: Abdel Azim, Ahmed
Publisher: name: University of Alberta Library
Year: 2023

This study investigates the complexity and the context of the construction industry and conditions where causes of disputes arise. The construction project life cycle needs management approaches that help to reduce conflicts in the first place, reduce risk and improve performance. According to lean, disagreements and disputes are waste; if eliminated, costs would be reduced, performance improved, and the health of the working environment would be sustained. Emerging collaborative project delivery methods involve key participants very early in the project, frequently even before the design phase. It is characterized with a multiparty contractual agreement that allow risk and rewards sharing among the stakeholders to mitigate them collaboratively. Although partnering may be a helpful solution to improve the situation by getting people to work together; however, it does not analyze the underlying issues that make the conditions difficult and contribute to uncertainty and disputes. Taking inspiration from lean and collaborative delivery methods, ECI is a project delivery method that can fill the partnering deficit gap. It would specify the time of contractor involvement to improve the design, increase productivity, reduce risk, improve performance, and sustain a healthy environment through constructability reviews, design assistance, or even taking over the design process. This study contributes to filling that missing gap by evaluating the impact of ECI that, if brought to the construction projects, would reduce the cause of disputes occurrence, and improve performance and relationships. According to the research findings, there are several pathways for ECI implementation, which indicates that there is no one strict rule, neither for its procurement evaluation nor for its contractual design. This means that ECI can be used in two stages for the same contractor, or it can use different contractors for each stage. It could also be done in different ways, such as with traditional DBB, DB, management contracting, project partnering, or alliancing. This study offers research opportunities and agendas to help academics and construction practitioners gain better knowledge that can help them design an appropriate ECI pathway that can improve the project’s performance and reduce surprises that might lead to conflicts and disputes. ECI has been shown to reduce various types of claims such as design, time extension, scope, liability, and termination claims. The results were confirmed with actual data from a case study in Canada, “170 Street over YHT—Bridge Rehabilitation”. Moreover, the study analyzes the ECI influence on the contractual risks through a comparison of two ECI contracts: CCGC contract form as adopted by the City of Edmonton in Canada and JCT (MC) as adopted in UK.
An analysis of the trade-off between spatial and temporal resources for measurement-based quantum computation

description: In measurement-based quantum computation (MBQC), elementary quantum operations can be more parallelized than the quantum circuit model by employing a larger Hilbert space of graph states used as the resource. Thus MBQC can be regarded as a method of quantum computation where the temporal resource described by the depth of quantum operations can be reduced compared to the quantum circuit model by using the extra spatial resource described by graph states. To analyze the trade-off relationship of the spatial and temporal resources, we consider a method to obtain quantum circuit decompositions of general unitary transformations represented by MBQC on graph states with a certain underlying geometry called generalized flow. We present a method to translate any MBQC with generalized flow into quantum circuits without extra spatial resource. We also show an explicit way to unravel acausal gates that appear in the quantum circuit decomposition derived by a translation method presented in [V. Danos and E. Kashefi, Phys. Rev. A {\bf 74}, 052310 (2006)] and that represent an effect of the reduction of the temporal resource in MBQC. Finally, by considering a way to deterministically simulate these acausal gates, we investigate a general framework to analyze the trade-off between the spacial and temporal resources for quantum computation.

description: Anomalous Hall effect (AHE) is a fundamental spin-dependent transport property that is widely used in spintronics. It is generally expected that currents carrying net spin polarization are required to drive the AHE. Here we demonstrate that, in contrast to this common expectation, a spin-neutral tunneling AHE (TAHE), i.e. a TAHE driven by spin-neutral currents, can be realized in an antiferromagnetic (AFM) tunnel junction where an AFM electrode with a non-spin-degenerate Fermi surface and a normal metal electrode are separated by a non-magnetic barrier with strong spin-orbit coupling (SOC). The symmetry mismatch between the AFM electrode and the SOC barrier results in an asymmetric spin-dependent momentum filtering of the spin-neutral longitudinal current generating the transverse Hall current in each electrode. We predict a sizable spin-neutral TAHE in an AFM tunnel junction with a RuO$_{2}$-type AFM electrode and a SnTe-type SOC barrier and show that the Hall currents are reversible by the Néel vector switching. With the Hall angle being comparable to that in conventional AHE bulk materials, the predicted spin-neutral TAHE can be used for the Néel vector detection in antiferromagnetic spintronics.

description: We use the EAGLE cosmological simulations to perform a comprehensive and systematic analysis of the $z=0.1$ Fundamental Plane (FP), the tight relation between galaxy size, mass and velocity dispersion. We first measure the total mass and velocity dispersion (including both random and rotational motions) within the effective radius to show that simulated galaxies obey a total mass FP that is very close to the virial relation ($<10\%$ deviation), indicating that the effects of non-homology are weak. When we instead use the stellar mass, we find a strong deviation from the virial plane, which is driven by variations in the dark matter content. The dark matter fraction is a smooth function of the size and stellar mass, and thereby sets the coefficients of the stellar mass FP without substantially increasing the scatter. Hence, both star-forming and quiescent galaxies obey the same FP, with equally low scatter (0.02 dex). We employ simulations with a variable stellar initial mass function (IMF) to show that IMF variations have a modest additional effect on this FP. Moreover, when we use luminosity-weighted mock observations of the size and spatially-integrated velocity dispersion, the inferred FP changes only slightly. However, the scatter increases significantly, due to the luminosity-weighting and line-of-sight projection of the velocity dispersions, and measurement uncertainties on the half-light radii. Importantly, we find significant differences between the simulated FP and observations, which likely reflects a systematic difference in the stellar mass distributions. Therefore, we suggest the stellar mass FP offers a simple test for cosmological simulations, requiring minimal post-processing of simulation data.

We remark the possibility of the contribution from non-equilibrium components at very low transverse momentum ($p_{T}$) region and show that such contributions significantly affect $p_{T}$-integrated four-particle cumulants. These results strongly suggest the necessity of non-equilibrium components when one extracts properties of the quark-gluon plasma from experimental data using sophisticated dynamical models based on relativistic hydrodynamics.

description: A joint degree matrix (JDM) specifies the number of connections between nodes of given degrees in a graph, for all degree pairs and uniquely determines the degree sequence of the graph. We consider the space of all balanced realizations of an arbitrary JDM, realizations in which the links between any two degree groups are placed as uniformly as possible. We prove that a swap Markov Chain Monte Carlo (MCMC) algorithm in the space of all balanced realizations of an {\em arbitrary} graphical JDM mixes rapidly, i.e., the relaxation time of the chain is bounded from above by a polynomial in the number of nodes $n$. To prove fast mixing, we first prove a general factorization theorem similar to the Martin-Randall method for disjoint decompositions (partitions). This theorem can be used to bound from below the spectral gap with the help of fast mixing subchains within every partition and a bound on an auxiliary Markov chain between the partitions. Our proof of the general factorization theorem is direct and uses conductance based methods (Cheeger inequality).

Maydanyk's Memories: A Juxtaposition of Time and Space
Creators: Sembaliuk Cheladyn, Larisa N
Publisher: name: University of Alberta Library
Year: 2023

Written nearly a century ago, Вуйкова книга Uncle’s Book by Jacob Maydanyk embodied the collective memories of early Ukrainian settlers on the Canadian prairies. It was Maydanyk’s graphic memoir, and over the years, time was unkind - the book of comic strips became a collection of forgotten immigrant voices, tucked away on dusty shelves and in broken boxes - until now. I was compelled to study Maydanyk’s collection because of our shared Ukrainian heritage and profession in the arts. I was also curious as to the positioning of this comic book in the canon of comics creation in Canada. I wondered how it came to be and its significance as a body of collective memories of early pioneer experiences and Canadian comics creation. This dissertation represents an interdisciplinary approach to gathering, and sharing Maydanyk's tangible and intangible memories that lead to the creation of Uncle’s Book. The theory of the dérive and psychogeographical observation facilitated contextualizing the information and uncovering new insights into the artist’s past. As research-creation, the approach involved a temporal journey through the streets of Winnipeg, MB and the backroads of Manitoba, coupled with an exploration of old and new media to create a website -The Maydanyk Digital Archives -connecting a generation of digitally savvy scholars with collective memories from the past. I found Maydanyk’s stories timeless – born in the past but still relevant today and worthy of our attention.
Modelling Beneficial Management Practices in Agriculture in Western Canada to Observe Impacts on Greenhouse Gas Emissions and Environmental Sustainability
Creators: Ducholke, Chloe J
Publisher: name: University of Alberta Library
Year: 2023

Reducing greenhouse gas (GHG) emissions and other detrimental environmental effects

of agriculture is a goal paramount to societal stability and prosperity. Understanding the

advantages and constraints of beneficial management practices (BMPs) to the fullest extent in

varying conditions is imperative for effectively selecting the right interventions tailored to

specific farming scenarios. Modelling agricultural management practices and scenarios enables

comprehensive testing of simulation experiments to be conducted efficiently, conveniently and at

low cost while yielding accurate, representative results. The objectives of this research include:

1) Identify and review existing BMPs for mitigation of GHG emissions within farming systems

relevant to the Canadian Prairies, 2) to implement the Holos model software to run simulations

of selected farming scenarios and management practices, and 3) to inform future research

recommendations in agricultural sustainability and identify existing knowledge gaps. The

scenarios modelled focused on the Canadian Prairies, and hence the modelled replicates were

evenly distributed across locations within Alberta, Saskatchewan, and Manitoba. A set of

beneficial management practices was modelled using the Holos model software. The greatest

reduction in farm GHG emissions occurred when nitrogen and phosphorus fertilizer inputs were

reduced. The average reduction in emissions from a regime of high inputs to conservative inputs

was 26% Kg CO2e. Across a variety of soil types and fertilizer regimes, the average reduction by

switching to no-till or reduced tillage from intensive tillage was 24.9% Kg CO2e and 17.6% Kg

CO2e respectively. This great reduction was attributed to increased soil carbon sequestration and

reduced fossil fuel emissions from farm equipment operations. Livestock dietary changes also

resulted in emissions reductions. A high protein diet for beef cattle caused a reduction of 33%

Kg CO2e when compared with a low protein diet. High protein diets can increase efficiency of

iii

feed utilization (EFU). Fat supplementation and use of ionophores were also found to reduce

emissions. Earlier studies have shown that both fat and ionophore supplements directly reduce

methane emissions from digestion for beef cattle. The GHG emissions estimates from the Holos

model suggest that implementation of beneficial management practices can play a large and

important role in reducing emissions in agriculture. These results contribute to a comprehensive,

valuable synthesis of the current knowledge base in BMPs for agricultural sustainability and

provide deployable insights to guide BMPs implementation

description: We review the work on data-driven grasp synthesis and the methodologies for sampling and ranking candidate grasps. We divide the approaches into three groups based on whether they synthesize grasps for known, familiar or unknown objects. This structure allows us to identify common object representations and perceptual processes that facilitate the employed data-driven grasp synthesis technique. In the case of known objects, we concentrate on the approaches that are based on object recognition and pose estimation. In the case of familiar objects, the techniques use some form of a similarity matching to a set of previously encountered objects. Finally for the approaches dealing with unknown objects, the core part is the extraction of specific features that are indicative of good grasps. Our survey provides an overview of the different methodologies and discusses open problems in the area of robot grasping. We also draw a parallel to the classical approaches that rely on analytic formulations.

description: Prediction of nucleation rates in first order phase transitions requires the knowledge of the barrier associated to the free energy profile $W$. Molecular simulations offer a direct route through $W = -kT \ln p_a$, where $k$ is Boltzmann's constant, $T$ is temperature, and $p_a$ the probability distribution of the size of any nucleus. But in practice, the extremely scarce spontaneous occurrence of large nuclei impedes the full determination of $p_a$, and a numerical bias must be introduced, e.g. on the size of the largest nucleus in the system, leading to the probability size distribution of the largest nucleus $p_l$. Although $p_l$ is known to be system size dependent, unlike $p_a$, it has been extensively used as an approximation for $p_a$. This paper proposes an exact relation between $p_a$ and $p_l$, which cures this approximation and allows an exact calculation of free energy barriers from biased simulations.

description: Interconversions of $W$ and Greenberger-Horne-Zeilinger states in various physical systems are lately attracting considerable attention. We address this problem in the fairly general physical setting of qubit arrays with long-ranged (all-to-all) Ising-type qubit-qubit interaction, which are simultaneously acted upon by transverse Zeeman-type global control fields. Motivated in part by a recent Lie-algebraic result that implies state-to-state controllability of such a system for an arbitrary pair of states that are invariant with respect to qubit permutations, we present a detailed investigation of the state-interconversion problem in the three-qubit case. The envisioned interconversion protocol has the form of a pulse sequence that consists of two instantaneous (delta-shaped) control pulses, each of them corresponding to a global qubit rotation, and an Ising-interaction pulse of finite duration between them. Its construction relies heavily on the use of the (four-dimensional) permutation-invariant subspace (symmetric sector) of the three-qubit Hilbert space. In order to demonstrate the viability of the proposed state-interconversion scheme, we provide a detailed analysis of the robustness of the underlying pulse sequence to systematic errors, i.e. deviations from the optimal values of its five characteristic parameters.

description: We present a method to determine the impurity Greens function of the interacting resonant level model (IRLM) using numerical simulation techniques based on the expansion of a resolvent expression in terms of Chebyshev polynomials. The iterative determination of the contributions to the expansion is based on a Density Matrix Renormalisation Group algorithm. The spectral function has lorentzian shape, where we can show that the width grows monotonically with the interaction on the contact link. Moreover, for values of the interaction compareable to the band width, there are additional peaks showing up for energies located outside the conduction band.

description: Some cosmological models with non-negligible dark energy fractions in particular windows of the pre-recombination epoch are capable of alleviating the Hubble tension quite efficiently, while keeping the good description of the data that are used to build the cosmic inverse distance ladder. There has been an intensive discussion in the community on whether these models enhance the power of matter fluctuations, leading {\it de facto} to a worsening of the tension with the large-scale structure measurements. We address this pivotal question in the context of several early dark energy (EDE) models, considering also in some cases a coupling between dark energy and dark matter, and the effect of massive neutrinos. We fit them using the Planck 2018 likelihoods, the supernovae of Type Ia from the Pantheon compilation and data on baryon acoustic oscillations. We find that ultra-light axion-like (ULA) EDE can actually alleviate the $H_0$ tension without increasing the values of $σ_{12}$ with respect to those found in the $Λ$CDM, whereas EDE with an exponential potential does not have any impact on the tensions. A coupling in the dark sector tends to enhance the clustering of matter, and the data limit a lot the influence of massive neutrinos, since the upper bounds on the sum of their masses are too close to those obtained in the standard model. We find that in the best case, namely ULA, the Hubble tension is reduced to $\sim 2σ$.

title: Wie lernwirksam sind Online-Tutorials? Lernerfolgskontrolle und Evaluation bibliothekarischer E-Learningangebote
Creators: name: Lemke, Michael
Publisher: name: University Library Heidelberg

description: Immer mehr wissenschaftliche Bibliotheken, insbesondere Hochschulbibliotheken, erweitern ihre E-Learningangebote um sogenannte Online-Tutorials. Solche interaktiven, multi-medialen Lernprogramme bieten den Nutzern die Möglichkeit, sich zeit- und ortsunabhängig selbständig grundlegende Themen der Bibliotheks- und Informationskompetenz anzueignen. In der bibliothekarischen Fachliteratur finden sich aber keine Aussagen darüber, in welchem Umfang und wie lerneffektiv diese – meist mit hohem Aufwand erstellte – Angebote tatsächlich genutzt werden. Um die Lernwirksamkeit überprüfen zu können, bedarf es Online-Tutorials, die über einen automatisierten elektronischen Test verfügen, anhand dessen Nutzer eigenständig den Erwerb der Lerninhalte kontrollieren können. Die vorliegende Arbeit versteht sich als ein Beitrag zur Konzeption evaluierbarer Online-Tutorials. Skizziert wird eine strukturierte Vorgehensweise zur Umsetzung von Tutorials, die statistisch auswertbare Daten zur Lerneffektivität generieren. Im Fokus stehen hierbei didaktische Bedingungen automatisierter Lernerfolgskontrollen und deren Umsetzung anhand sogenannter geschlossener Aufgaben. Da sich mit diesem Aufgabentypus nur bestimmte kognitive Leistungsbereiche messen lassen, ist im Vorfeld zu prüfen, dass ein Tutorial nur Lerninhalte vermittelt, deren Erwerb anschließend auch mit geschlossenen Aufgaben überprüft werden kann. Unter Rückgriff auf eine spezifische E-Learning-Taxonomie wird offensichtlich, dass mindestens Reproduktions-, Verständnis- und Anwendungsleistungen umsetzbar sind. Wie entsprechende Aufgabenstellungen in bibliothekarischen Online-Tutorials aussehen können, wird an Beispielfragen zur Überprüfung von Fakten-, Konzept- und Prozedurenwissen demonstriert.

Interface Management advancement using Risk Assessments
Creators: de Ruiter, Nathaniel
Publisher: name: University of Alberta Library
Year: 2023

Interfaces on construction projects expose owners to risks that often result in substantial impacts to project cost, schedule, and goals (e.g., management of quality and reputation). Interfaces arise from boundary points where interdependency exists, such as physical elements, phases, contracts, tools, people, and organizations. Interface management is the practice of identifying, monitoring, and controlling interface problems. There is still an open question among owners as to how best to address interface problems, and there is relatively little research available in the literature that explores the implementation of interface management. Therefore, this thesis draws from another field, risk management, in order to better understand interface management. The methodology involves mapping risk assessment data from Light Rail Transit projects onto an existing register of 47 interface problems and 6 summarizing factors. Based on this, severity values from the risk assessments are reflected within the interface problems and factors, allowing for the interface problems and factors to be sorted in terms of importance. The results suggest that the most important interface factor is the “management factor”, followed by the “bidding and contracting factor”, while the leading interface problems are “inadequate negotiation, communication, and coordination”, followed by “unclear contract details and poorly written contract”. The objective underlying this thesis is to inform project managers as to where they should focus attention and resources, since mitigating the top interface problems will help to improve overall project performance.
title: Sind wir wirklich reif für E-only? Nutzerbedarf und Leseverhalten als Kriterien einer monographischen Erwerbungspolitik an wissenschaftlichen Bibliotheken

description: Mit der Lizenzierung von E-Book-Paketen und einem Einstieg in PDA-Modelle erwirbt das wissenschaftliche Bibliothekswesen zumindest partiell Monographien primär in elektronischer statt in gedruckter Form. Doch wollen und können Nutzer wissenschaftlicher Bibliotheken tatsächlich auf gedruckte Bücher verzichten? Entlang der Kernfrage, ob diese funktional durch E-Books ersetzbar sind, versucht der vorliegende Beitrag eine entsprechende Bestandsaufnahme. Wissenschaftler und Studenten praktizieren im Umgang mit Monographien sowohl kursorische als auch intensive Lesetechniken. Umfragen zeigen aber, dass Bibliotheksnutzer E-Books meist nur kursorisch lesen und dementsprechend kaum bereit sind, auf gedruckte Bücher zu verzichten. Dass sich an diesem Meinungsbild in absehbarer Zeit grundsätzlich etwas ändern wird, ist fraglich, da weder mit E-Book-Readern noch mit Tablet-PCs momentan ein Konzept für ein mobiles Endgerät vorliegt, mit dem sich sämtliche im wissenschaftlichen Kontext erforderliche Lesetechniken adäquat umsetzen ließen. Generell erweist sich das Lesen auf Papier immer noch als effizienter als das Lesen am Bildschirm. Dies lässt sich zwar zum einen auf temporäre, prinzipiell aufhebbare Faktoren zurückführen, wie z. B. einer geringeren Lerneinstellung gegenüber E-Medien, zum anderen aber auch auf grundlegende Unterschiede, die insbesondere in einer mangelhaften räumlichen und damit weniger übersichtlichen Wiedergabe umfangreicherer Texte zu suchen sind. Vor diesem Hintergrund stellt sich letztlich die Frage, weshalb wissenschaftliche E-Books, die lediglich einen eingeschränkten Lesekomfort bieten, als hochpreisiges Medium gehandelt und von bibliothekarischer Seite anscheinend auch selbstverständlich als solches akzeptiert werden.
