description: This paper studies one aspect of economic reforms -- privatization. By comparing privatization experiences and the degree of urgency in Mainland China, Taiwan (China) and Russia, I argue that privatization is necessary and inevitable, but not a precondition for economic reforms. Due to different economic structures and initial conditions, China and Taiwan (China) chose to restructure their economies without emphasizing privatization, and their reforms have been very successful. The rapid growth of Mainland China and Taiwan (China) has mainly come from resource reallocation, namely, industrialization -- cheap rural labor moving from a low productivity agricultural sector to the industrial sector. Russia, on the other hand, faces a very different problem: At the time of its reorientation to a market economy, Russia was already highly industrialized, with a very small proportion of rural labor, but a large number of inefficient public enterprises. Therefore, promoting efficiency and restructuring the industrial sector are the key to Russia's economic reform. Theoretically it may have been more appropriate for Russia to go through privatization at an earlier stage than China and Taiwan due to the fact that Russia had a much larger percentage of public enterprises, but it was unable to accomplish this efficiently.

description: This article proposes puppetry as a practice uniquely situated to intervene in ideological constructions of the disabled body both onstage and off. Examining our current and recent practice-based research that uses puppetry to intervene in cultural perceptions of disability, we put forth a provocation, asking readers to consider the ways in which puppetry practices can be deployed to enable performances by disabled puppeteers as well as in ways that engage with cultural constructions of disability. We suggest that puppets, as bodies that are materially constructed, can both reinforce and rupture such constructions.

description: In the context of hard hadronic reactions diquarks are a useful phenomenological device to model non-perturbative effects still observable in the kinematic range accessible by present-day experiments. In the following we present diquark-model predictions for $γγ\to p \bar{p}$ and $Λ\barΛ$. We also sketch how the (pure quark) hard-scattering formalism for exclusive reactions involving baryons can be reformulated in terms of quarks and diquarks. As an application of these considerations we analyze the magnetic proton form factor with regard to its quark-diquark content.

description: We introduce a minimum tight-binding model with only three parameters extracted from graphene and untwisted bilayer graphene. This model reproduces quantitatively the electronic structure of not only these two systems and bulk graphite near the Fermi level, but also that of twisted bilayer graphene including the value of the magic angle, at which bands at $E_F$ flatten without overlap and two gaps open, one above and one below $E_F$. The Hamiltonian is sufficiently transparent and flexible to be adopted to other twisted layered systems.

description: A key question for understanding the cross-section of expected returns of equities is the following: which factors, from a given collection of factors, are risk factors, equivalently, which factors are in the stochastic discount factor (SDF)? Though the SDF is unobserved, assumptions about which factors (from the available set of factors) are in the SDF restricts the joint distribution of factors in specific ways, as a consequence of the economic theory of asset pricing. A different starting collection of factors that go into the SDF leads to a different set of restrictions on the joint distribution of factors. The conditional distribution of equity returns has the same restricted form, regardless of what is assumed about the factors in the SDF, as long as the factors are traded, and hence the distribution of asset returns is irrelevant for isolating the risk-factors. The restricted factors models are distinct (nonnested) and do not arise by omitting or including a variable from a full model, thus precluding analysis by standard statistical variable selection methods, such as those based on the lasso and its variants. Instead, we develop what we call a Bayesian model scan strategy in which each factor is allowed to enter or not enter the SDF and the resulting restricted models (of which there are 114,674 in our empirical study) are simultaneously confronted with the data. We use a Student-t distribution for the factors, and model-specific independent Student-t distribution for the location parameters, a training sample to fix prior locations, and a creative way to arrive at the joint distribution of several other model-specific parameters from a single prior distribution. This allows our method to be essentially a scaleable and tuned-black-box method that can be applied across our large model space with little to no user-intervention. The model marginal likelihoods, and implied posterior model probabilities, are compared with the prior probability of 1/114,674 of each model to find the best-supported model, and thus the factors most likely to be in the SDF. We provide detailed simulation evidence about the high finite-sample accuracy of the method. Our empirical study with 13 leading factors reveals that the highest marginal likelihood model is a Student-t distributed factor model with 5 degrees of freedom and 8 risk factors.

description: We consider a finite-armed structured bandit problem in which mean rewards of different arms are known functions of a common hidden parameter $θ^*$. Since we do not place any restrictions of these functions, the problem setting subsumes several previously studied frameworks that assume linear or invertible reward functions. We propose a novel approach to gradually estimate the hidden $θ^*$ and use the estimate together with the mean reward functions to substantially reduce exploration of sub-optimal arms. This approach enables us to fundamentally generalize any classic bandit algorithm including UCB and Thompson Sampling to the structured bandit setting. We prove via regret analysis that our proposed UCB-C algorithm (structured bandit versions of UCB) pulls only a subset of the sub-optimal arms $O(\log T)$ times while the other sub-optimal arms (referred to as non-competitive arms) are pulled $O(1)$ times. As a result, in cases where all sub-optimal arms are non-competitive, which can happen in many practical scenarios, the proposed algorithms achieve bounded regret. We also conduct simulations on the Movielens recommendations dataset to demonstrate the improvement of the proposed algorithms over existing structured bandit algorithms.

description: A number of tests have been proposed for assessing the location-scale assumption that is often invoked by practitioners. Existing approaches include Kolmogorov–Smirnov and Cramer–von Mises statistics that each involve measures of divergence between unknown joint distribution functions and products of marginal distributions. In practice, the unknown distribution functions embedded in these statistics are typically approximated using nonsmooth empirical distribution functions (EDFs). In a recent article, Li, Li, and Racine establish the benefits of smoothing the EDF for inference, though their theoretical results are limited to the case where the covariates are observed and the distributions unobserved, while in the current setting some covariates and their distributions are unobserved (i.e., the test relies on population error terms from a location-scale model) which necessarily involves a separate theoretical approach. We demonstrate how replacing the nonsmooth distributions of unobservables with their kernel-smoothed sample counterparts can lead to substantial power improvements, and extend existing approaches to the smooth multivariate and mixed continuous and discrete data setting in the presence of unobservables. Theoretical underpinnings are provided, Monte Carlo simulations are undertaken to assess finite-sample performance, and illustrative applications are provided.

description: Covariant field equations of M-fivebrane in eleven dimensional curved superspace are obtained from the requirement of kappa-symmetry of an open supermembrane ending on a fivebrane. The worldvolume of the latter is a (6|16) dimensional supermanifold embedded in the (11|32) dimensional target superspace. The kappa-symmetry of the system imposes a constraint on this embedding, and a constraint on a modified super 3-form field strength on the fivebrane worldvolume. These constraints govern the dynamics of the M-fivebrane.

description: The production of jets in charged current deep inelastic scattering (CC DIS) constitutes a class of observables that can be used to simultaneously test perturbative predictions for the strong and the electroweak sectors of the Standard Model. We compute both single jet and di-jet production in CC DIS for the first time at next-to-next-to-leading order (NNLO) in the strong coupling. Our computation is fully differential in the jet and lepton kinematics, and we observe a substantial reduction of scale variation uncertainties in the NNLO predictions compared to next-to-leading order (NLO). Our calculation will prove essential for full exploitation of data at a possible future LHeC collider.

Zur Abscheidung von Tröpfchen-Aerosolen in filternden Abscheidern
Creators: name: Hassel, Richard
Publisher: name: Universität Paderborn
Year: 2023

description: Die Abscheidung von Tröpfchen-Aerosolen, welche in zahlreichen verschiedenen Prozessen entstehen und in der Regel unerwünscht sind, stellt bis heute eine große Herausforderung dar. Auch vor der Einspeisung von Brenngas in Gasturbinen entstehen Flüssigkeitspartikeln, die den Prozess der Stromerzeugung negativ beeinflussen. Die Konsequenzen daraus sind Wirkungsgradeinbußen und vermeidbare Umweltbelastung. Die höchste Reinheit garantieren dabei bis heute filternde Abscheider. In dieser Arbeit soll die Möglichkeit betrachtet werden, den Abscheideprozess mathematisch mit Hilfe eines Zellmodells zu modellieren. Dafür wird jeder Schritt des Separationsprozesses genauer betrachtet. Der Gesamtprozess der Phasenseparation kann in vier einzelne Prozessschritte gegliedert werden: Das Einfangen der Aerosoltropfen, die Koaleszenz der Einzeltropfen im Filtermedium, der Flüssigkeitstransport durch das Filtermedium und der Flüssigkeitsaustrag auf der strömungsabgewandten Seite. Bei den Untersuchungen steht insbesondere die Flüssigkeitsverteilung im Vordergrund. Dafür wurde ein Versuchsstand entwickelt und aufgebaut, der den Filtrationsprozess von Tröpfchen-Aerosol simuliert. Zusätzlich wurde das Filtermaterial mit verschiedenen Messmethoden charakterisiert. Abschließend wurde eine Bewertung zur Machbarkeit gegeben.
description: The separation of droplet aerosol, which is generated in numerous different processes and is usually undesirable, remains a major challenge today. Even before fuel gas is fed into gas turbines, liquid particles are produced that have a negative impact on the power generation process. The consequences of this are energy loss and avoidable environmental pollution. To this day, the highest purity is guaranteed by filtering separators.In this thesis, the possibility of mathematically modelling the separation process with the help of a cell model is considered. For this purpose, each step of the separation process will be considered in detail. The overall process of phase separation can be divided into four individual process steps: The capture of the aerosol droplets, the coalescence of the individual droplets on the fibres of the filter medium, the liquid transport through the filter medium, and the liquid discharge on the side of the filter medium facing away from the flow. The investigations focus in particular on the liquid distribution. For this purpose, a test rig was developed and set up that simulate the filtration process of droplet aerosol. In addition, the filter material was characterised using various measurement methods. Finally, a feasibility assessment was given.

description: We construct phenomenological quark-lepton mass matrices based on S$_3$ permutation symmetry in a manner fully compatible with SU(5) grand unification. The Higgs particles we need are {\bf 5}, {\bf 45} and their conjugates. The model gives a charge $-$1/3 quark vs charged lepton mass relation, and also a good fit to mass-mixing relations for the quark sector, as well as an attractive mixing pattern for the lepton sector, explaining a large mixing angle between $ν_μ$ and $ν_τ$, and either large or small $ν_e-ν_μ$ mixing angle, depending on the choice of couplings, consistent with the currently accepted solutions to the solar neutrino problem.

description: In a world that is highly infused with technology, it is important that an organization knows how many resources such as manpower, equipment, and funding are needed at what time so that the organization does not suffer unnecessary risks. It is also important to know when to replace equipment. After examining different methods of forecasting, it was determined that manipulation of growth curves was the best way to determine the likelihood of device failure at a specific time. An approach in engineering economics was used to estimate the cost due to the failure of various devices or groups of devices.

To reduce the likelihood of making mistakes in calculating the probability of device failure and its costs, a MatLab program was developed as a key output of this thesis. The program has a set of graphical user interfaces that use s-curves for measuring the growth, decay, and substitution of one type of device by another in the market. A by-product of this thesis is the publication of an operating manual for this program.

description: Motivated by the need for an absolute polarimeter to determine the beam polarization for the forthcoming RHIC spin program, we study the spin dependence of the proton-proton elastic scattering amplitudes at high energy and small momentum transfer.We examine experimental evidence for the existence of an asymptotic part of the helicity-flip amplitude phi_5 which is not negligible relative to the largely imaginary average non-flip amplitude phi_+. We discuss theoretical estimates of r_5, essentially the ratio of phi_5 to phi_+, based upon extrapolation of low and medium energy Regge phenomenological results to high energies, models based on a hybrid of perturbative QCD and non-relativistic quark models, and models based on eikonalization techniques. We also apply the model-independent methods of analyticity and unitarity.The preponderence of evidence at available energy indicates that r_5 is small, probably less than 10%. The best available experimental limit comes from Fermilab E704:those data indicate that |r_5|<15%. These bounds are important because rigorous methods allow much larger values. In contradiction to a widely-held prejudice that r_5 decreases with energy, general principles allow it to grow as fast as ln(s) asymptotically, and some models show an even faster growth in the RHIC range. One needs a more precise measurement of r_5 or to bound it to be smaller than 5% in order to use the classical Coulomb-nuclear interference technique for RHIC polarimetry. As part of this study, we demonstrate the surprising result that proton-proton elastic scattering is self-analysing, in the sense that all the helicity amplitudes can, in principle, be determined experimentally at small momentum transfer without a knowledge of the magnitude of the beam and target polarization.
SYSTEMS BIOLOGY STUDY OF KIFC1, CENTROSOME AMPLIFICATION AND CELL CYCLE RELATIONSHIPS
Creators: name: Fielding, Andrew
name: O'Shea, Paul
name: Zilinskas, Linas
Publisher: name: Lancaster University
Year: 2025

description: Many cancer cells exhibit the state known as centrosome amplification,
 where they have more than two centrosomes as they undergo mitosis. In
 order to cope with centrosome amplification, cells require mechanisms to
 cluster their amplified centrosomes. KIFC1 is a kinesin that performs the
 clustering of multiple centrosomes and this function allows survival of
 cells with centrosome

 amplification. KIFC1 is best known for its ability to cluster centrosomes,
 with minor evidence suggestive of some functions in the cell cycle.
 Meanwhile, the centrosome is well known for its ability to separate
 chromosomes, receiving much less attention for housing many cell cycle
 proteins and associated events.

 Here, the aim was to examine the relationships between the cell cycle,
 centrosome amplification and KIFC1 function, in particular how centrosome
 amplification affects the cell cycle lengths and parameters occurring on
 centrosomes and how KIFC1 affects the lengths of the phases of the cell

 cycle.

 The link between KIFC1 and cell cycle lengths and between centrosomes and
 cell cycle lengths has been investigated and it was found that KIFC1
 depletion increases the lengths of G1 phase and the period of the cell
 cycle from S to Anaphase for both cells with normal and amplified
 centrosome number. KIFC1 depletion also results into a lower proportional
 increase of the number of cells in a population over time by 33.5 times.
 Amplified centrosomes have shown no effect on the length of the cell
 cycle. To further investigate the effect of centrosomes on the cell cycle,
 a systemic method has been utilized to identify proteins specific for the
 cell cycle that could be affected by centrosome amplification, potentially
 modyfing their cell cycle functions; PLK1, and AURKA, in particular the
 phosphorylated versions of both. It was found that centrosome
 amplification affects the amounts and activity of these proteins at
 centrosomes and disturbs certain relationships between the centrosomal
 parameters and parameters of these proteins.
Computing splitting fields and galois groups over local function fields

description: In dieser Doktorarbeit wird ein Algorithmus zum Berechnen von Galoisgruppen über lokalen Funktionenkörpern entwickelt. Dabei wird eine Variante des Zerfällungskörper-Algorithmus verwendet und ausgenutzt, dass lokale Funktionenkörper isomorph zu einem Laurentreihenring über endlichen Körpern sind. Diese Idee reduziert die Komplexität der benötigten Polynomfaktorisierungen. Die Kombination dieses Ansatzes mit Verzweigungspolygonen, welche in der Doktorarbeit von Greve zur Berechnung von Galoisgruppen über p-adischen Körpern eingeführt wurden, liefert eine weitere Verbesserung. Alle in der Arbeit vorgestellten Algorithmen wurden im Computeralgebrasystem Magma implementiert. Darüber hinaus wird der Algorithmus zum Berechnen von Minimalpolynomen in lokalen Funktionenkörpern verbessert. Dies beschleunigt die Berechnung von Zerfällungskörpern über diesen Körpern. Insgesamt ergibt sich die erste Implementierung eines Algorithmus zum Berechnen von Galoisgruppen über lokalen Funktionenkörpern. Anhand von einer Vielzahl von Beispielen wird die Effizienz des Ansatzes demonstriert. So wird z.B. ein Zerfällungskörper vom Grad 522240 bestimmt.
description: In this thesis, we develop an algorithm for computing Galois groups over local function fields. We use a variation of a splitting field approach by taking advantage of the fact that all local function fields are isomorphic to a Laurent series ring over a finite field. This idea reduces the complexity of the necessary factorizations of polynomials. By combining this with ramification polygons used in Greve's PhD-thesis for computing Galois groups over p-adic fields, we got further improvements. All algorithms presented in this thesis have been implemented in the computer algebra system Magma. Moreover, the algorithm for computing the minimal polynomial of elements in local function fields has been improved. This speeds up the factoring algorithm of polynomials over local function fields. As a result, we get the first implemented algorithm for computing Galois groups over local function fields. We demonstrate the efficiency by providing a large number of examples, where the resulting splitting fields have degrees up to 522240.

description: Recent work has emphasized the importance of evaluating estimates of a statistical functional (such as a conditional mean, quantile, or distribution) using a loss function that is consistent for the functional of interest, of which there is an infinite number. If forecasters all use correctly specified models free from estimation error, and if the information sets of competing forecasters are nested, then the ranking induced by a single consistent loss function is sufficient for the ranking by any consistent loss function. This article shows, via analytical results and realistic simulation-based analyses, that the presence of misspecified models, parameter estimation error, or nonnested information sets, leads generally to sensitivity to the choice of (consistent) loss function. Thus, rather than merely specifying the target functional, which narrows the set of relevant loss functions only to the class of loss functions consistent for that functional, forecast consumers or survey designers should specify the single specific loss function that will be used to evaluate forecasts. An application to survey forecasts of U.S. inflation illustrates the results.

description: 1I/'Oumuamua is the first interstellar object observed passing through the Solar System. Understanding the nature of these objects will provide crucial information about the formation and evolution of planetary systems, and the chemodynamical evolution of the Galaxy as a whole. We obtained the galactic orbital parameters of this object, considering 8 different models for the Galaxy, and compared it to those of stars of different ages from the Geneva-Copenhagen Survey (GCS). Assuming that the galactic orbital evolution of this object is similar to that of stars, we applied a Bayesian analyses and used the distribution of stellar velocities, as a function of age, to obtain a probability density function for the age of 'Oumuamua. We considered two models for the age-velocity dispersion relation (AVR): the traditional power law, fitted using data from the GCS; and a model that implements a second power law for younger ages, which we fitted using a sample of 153 Open Clusters (OCs). We find that the slope of the AVR is smaller for OCs than it is for field stars. Using these AVRs, we constrained an age range of 0.01-1.87 Gyr for 'Oumuamua and characterized a most likely age ranging between 0.20-0.45 Gyr, depending on the model used for the AVR. We also estimated the intrinsic uncertainties of the method due to not knowing the exact value of the Solar motion and the particularities of 1I/'Oumuamua's ejection.

description: This article proposes a new method for estimating heterogeneous externalities in policy analysis when social interactions take the linear-in-means form. We establish that the parameters of interest can be identified and consistently estimated using specific functions of the share of the eligible population. We also study the finite sample performance of the proposed estimators using Monte Carlo simulations. The method is illustrated using data on the PROGRESA program. We find that more than 50% of the effects of the program on schooling attendance are due to externalities, which are heterogeneous within and between poor and nonpoor households.

description: In a sample of 7.8 million $J/ψ$ decays collected in the Beijing Spectrometer, the process J/$ψ\toγη_c$ is observed for five different $η_c$ decay channels: $K^+K^-π^+π^-$, $π^+π^-π^+π^-$, $K^\pm K^0_S π^\mp$ (with $K^0_S\toπ^+π^-$), $ϕϕ$ (with $ϕ\to K^+K^-$) and $K^+K^-π^0$. From these signals, we determine the mass of $η_c$ to be $2976.6\pm2.9\pm1.3$ MeV. Combining this result with a previously reported result from a similar study using $ψ(2S)\toγη_c$ detected in the same spectrometer gives $m_{η_c} = 2976.3\pm2.3\pm1.2$ MeV. For the combined samples, we obtain $Γ_{η_c} = 11.0\pm 8.1\pm 4.1$ MeV.

description: The charge-asymmetry observed in a recent CPLEAR experiment was interpreted by the authors as a direct observation of T-noninvariance. While this is the simplest and most natural inference, and the observed effect agrees in sign and magnitude with theoretical expectation, adherents of T-invariance may argue that other interpretations are also possible. If K^0 and \bar{K}^0 are produced equally in \bar{p} p annihilation, and T-invariance is assumed to hold, the asymmetry observed in CPLEAR must be attributed to TCP-noninvariance of kaon beta-decays. If that were the case, the charge-asymmetry in K_S^0 \to πlνdecays should be three times larger than the one observed for K_L^0 decays.

description: A key question for understanding the cross-section of expected returns of financial equity assets is the following: which factors, from a given collection of factors, are risk factors, equivalently, which factors are in the stochastic discount factor (SDF)? Though the SDF is unobserved, assumptions about which factors (from the available set of factors) are in the SDF restricts the joint distribution of factors in specific ways, as a consequence of the economic theory of asset pricing. A different starting collection of factors that go into the SDF leads to a different set of restrictions on the joint distribution of factors. The conditional distribution of equity returns has the same restricted form, regardless of what is assumed about the factors in the SDF, as long as the factors are tradeable, and hence the distribution of asset returns is irrelevant for isolating the risk-factors. The restricted factors models are distinct (non-nested) and do not arise by omitting or including a variable from a full model, thus precluding analysis by standard statistical variable selection methods, such as those based on the lasso and its variants. Instead, we develop what we call a Bayesian model scan strategy in which each factor is allowed to enter or not enter the SDF and the resulting restricted models (of which there are 114,674 in our empirical study) are simultaneously confronted with the data. We use a student-t distribution for the factors, and model-specific independent student-t distribution for the location parameters, a training sample to fix prior locations, and a creative way to arrive at the joint distribution of several other model-specific parameters from a single prior distribution. This allows our method to be essentially a scaleable and tuned-black-box method that can be applied across our large model space with little to no user-intervention. The model marginal likelihoods, and implied posterior model probabilities, are compared with the prior probability of 1/114,674 of each model to find the best supported model, and thus the factors most likely to be in the SDF. We provide detailed simulation evidence about the high finite-sample accuracy of the method. Our empirical study with 13 leading factors reveals that the highest marginal likelihood model is a student-t distributed factor model with 5 degrees of freedom and 8 risk factors.

description: We analysed with landmark-based images morphological differences between four species of Talpa which resemble each other morphologically and are all highly adapted to underground life. Subtle shape differences of the skull and mandibular bones were found between all species. However, there is also broad overlap between all species. Talpa caucasica had the largest skull and mandibles, and Talpa levantis the smallest.
The Supersymmetric R-Parity Violating Dine-Fischler-Srednicki-Zhitnitsky Axion Model

description: We propose a complete R-parity violating supersymmetric model with baryon triality that contains a Dine-Fischler-Srednicki-Zhitnitsky axion chiral superfield. We parametrize supersymmetry breaking with soft terms, and determine under which conditions the model is cosmologically viable. As expected we always find a region of parameter space in which the axion is a cold dark matter candidate. The mass of the axino, the fermionic partner of the axion, is controlled by a Yukawa coupling. When heavy [${\mathcal O}$(TeV)], the axino decays early and poses no cosmological problems. When light [$\mathcal{O}$(keV)] it can be long lived and a warm dark matter candidate. We concentrate on the latter case and study in detail the decay modes of the axino. We find that constraints from astrophysical X- and gamma rays on the decay into photon and neutrino can set new bounds on some trilinear supersymmetric R-parity violating Yukawa couplings. In some corners of the parameter space the decays of a relic axino can also explain a putative 3.5 keV line.

description: This paper proposes a new method for estimating heterogeneous externalities in policy analysis when social interactions take the linear-in-means form. We establish that the parameters of interest can be identified and consistently estimated using specific functions of the share of the eligible population. We also study the finite sample performance of the proposed estimators using Monte Carlo simulations. The method is illustrated using data on the PROGRESA program. We find that more than 50 percent of the effects of the program on schooling attendance are due to externalities, which are heterogeneous within and between poor and nonpoor households.
Causal Perturbation Theory and Differential Renormalization

description: In Causal Perturbation Theory the process of renormalization is precisely equivalent to the extension of time ordered distributions to coincident points. This is achieved by a modified Taylor subtraction on the corresponding test functions. I show that the pullback of this operation to the distributions yields expressions known from Differential Renormalization. The subtraction is equivalent to BPHZ subtraction in momentum space. Some examples from Euclidean scalar field theory in flat and curved spacetime will be presented.

Ferromagnetic Josephson junctions for cryogenic memory

description: Josephson junctions containing ferromagnetic materials have attracted intense interest both because of their unusual physical properties and because they have potential application for cryogenic memory. There are two ways to store information in such a junction: either in the amplitude of the critical current or in the ground-state phase difference across the junction; the latter is the topic of this paper. We have recently demonstrated two different ways to achieve phase control in such junctions: the first uses junctions containing two magnetic layers in a "pseudo spin valve" configuration, while the second uses junctions containing three magnetic layers with non-collinear magnetizations. The demonstration devices, however, have not yet been optimized for use in a large-scale cryogenic memory array. In this paper we outline some of the issues that must be considered to perform such an optimization, and we provide a speculative "phase-diagram" for the nickel-permalloy spin-valve system showing which combinations of ferromagnetic layer thicknesses should produce useful devices.

How Digital Storytelling Can Be Used in Postsecondary Instruction: A case study of ds106, an online course at the University of Mary Washington
Creators: Gerris, Brittany

Digital storytelling has existed since the early 1990s and has since been adapted for use in various educational settings. With changing technologies and pedagogical techniques, the traditional definition coined by the StoryCenter of a true story as one told using video, voice over, audio, and images does not fit today’s digital culture. Classrooms and storytellers are moving to a more diverse definition of digital storytelling that incorporates different forms of media and focusing on a range of stories beyond personal, non-fiction ones. New ways to engage students and spark interest in course content while teaching valuable skills are consistently in demand for educators; digital storytelling could be a tool for postsecondary instructors or other levels with alteration. Guided by the narrative paradigm and the theoretical perspective of connectivism, the research examined a case study of publicly posted student work for indications of favourable reactions of digital storytelling assignments, characteristics that interest learners, and levels of student engagement to help improve future digital storytelling pedagogy. This Capstone project explores various forms of digital storytelling through the case study of an open access online undergraduate class taught at the University of Mary Washington nicknamed ds106 from January to April 2022. Three assignments spread out over the semester were evaluated using qualitative deductive content analysis techniques for reaction, effort, completeness, and deadline adherence. Inductive coding was used for topics of student submissions and tones used in both submissions and peer comments on the identified assignments. It was discovered that within this course, students reacted most favourably to assignments where they were given creative freedom and where they were provided opportunities to revisit and improve their own work. As the case study only included 17 students’ work, interpretations are not widely applicable, but observations and resources will benefit digital storytelling facilitators.

description: Sustainable Development Goals have brought optimism around ‘agriculture for development’ but also questioned agribusinesses in sustainable development. This paper assesses how an agribusiness’ power exploits domains to exert control over industry governance. Using interviews and group discussions from three smallholder outgrower schemes under Illovo Sugar Plc in Zambia, the paper demonstrates that corporations can deploy the ‘power of presence’ to influence national policy development, and sustainability in regional and local practices. Investment and trade policies currently foster agribusinesses but overlook environmental assessments that expose social and ecological contradictions such as on competing water uses. State-donor relations enable smallholder integration in sugarcane as poverty reduction whilst agribusinesses are limiting their participation through controls on resources and production systems. By analysing power expressions, we show how possibilities of sustainable agriculture and rural development are undermined by agribusiness practices. We suggest that current policy efforts around ‘agriculture for development’ in Zambia are about entrenching power and interests of an agribusiness, neglecting industry expansion and sustainability. The paper highlights the limits and importance of domestic institutions in framing large-scale agricultural investments as well as mediating corporate practices that will be required to provide a greater focus on national planning processes for sustainable agriculture and rural development.
