description: This paper is an empirical investigation of the role of the financial sector in the EU Emissions Trading Scheme (EU ETS). This topic is of particular interest because non-regulated entities are likely to have played an important part in increasing the efficiency of the EU ETS by reducing trading transaction costs and providing other services. Due to various reasons (new rules and regulations, reduced return prospects, VAT fraud investigations) banks have reduced their engagement in EU Emissions Trading and it is unclear how this will impact on the functioning of the carbon market. Our regression analysis based on data from the EU Transaction Log shows that large companies and companies with extensive trading experience are more likely to interact with the financial sector, which is why we expect banks’ pulling out of the EU ETS to affect larger companies more significantly. The semi-structured interviews we conducted with representatives of the financial sector, as well as companies liable under the EU ETS, confirm that banks were involved in the EU carbon market in various capacities, specifically as hedging partners for larger companies in the energy sector. Whether this particular role may be taken on by other financial players is unknown at this stage.

description: Types in logic programming have focused on conservative approximations of program semantics by regular types, on one hand, and on type systems based on a prescriptive semantics defined for typed programs, on the other. In this paper, we define a new semantics for logic programming, where programs evaluate to true, false, and to a new semantic value called wrong, corresponding to a run-time type error. We then have a type language with a separated semantics of types. Finally, we define a type system for logic programming and prove that it is semantically sound with respect to a semantic relation between programs and types where, if a program has a type, then its semantics is not wrong. Our work follows Milner's approach for typed functional languages where the semantics of programs is independent from the semantic of types, and the type system is proved to be sound with respect to a relation between both semantics.

description: This paper presents the concept and experience of teaching an undergraduate course on data-driven image and video processing. When designing visual effects that make use of Machine Learning (ML) models for image-based analysis or processing, the availability of training data typically represents a key limitation when it comes to feasibility and effect quality. The goal of our course is to enable students to implement new kinds of visual effects by acquiring training datasets via crowdsourcing that are used to train ML models as part of a video processing pipeline. First, we propose our course structure and best practices that are involved with crowdsourced data acquisitions. We then discuss the key insights we gathered from an exceptional undergraduate seminar project that tackles the challenging domain of video annotation and learning. In particular, we focus on how to practically develop annotation tools and collect high-quality datasets using Amazon Mechanical Turk (MTurk) in the budget- and time-constrained classroom environment. We observe that implementing the full acquisition and learning pipeline is entirely feasible for a seminar project, imparts hands-on problem solving skills, and promotes undergraduate research.

description: We introduce structured random matrix ensembles, constructed to model many-body quantum systems with local interactions. These ensembles are employed to study equilibration of isolated many-body quantum systems, showing that rather complex matrix structures, well beyond Wigner's full or banded random matrices, are required to faithfully model equilibration times. Viewing the random matrices as connectivities of graphs, we analyse the resulting network of classical oscillators in Hilbert space with tools from network theory. One of these tools, called the maximum flow value, is found to be an excellent proxy for equilibration times. Since maximum flow values are less expensive to compute, they give access to approximate equilibration times for system sizes beyond those accessible by exact diagonalisation.

description: The production of black holes in extra-dimensional brane-world theories can lead to detectable signals via the Hawking evaporation of the black hole to brane-localised Standard Model modes. We calculate, as a function of partial wave number and number of toroidally compactified extra dimensions, the leading correction to the energy spectrum of such Hawking radiation (the greybody factors) for decay into spin 1/2 fermions and spin 1 gauge fields localised on the Standard Model brane. We derive the associated improved differential emission rates for both types of fields. We provide both simple expressions for the leading behavior of the greybody factors in the low-energy limit $\om r_H \ll 1$, and numerical evaluation of our full analytic expressions for the emission rates, valid for $\om r_H \sim 1$. The full analytic expressions demonstrate that both the greybody factors and emission rates are enhanced as the number of extra dimensions increases.

Constraints on heavy Z' couplings from ΔS = 2 B^- -> K^- K^- π^+ decay

description: The heavy Z' boson with family nonuniversal couplings can introduce flavour changing effects. Constraints on nondiagonal Z' couplings coming from the μ-e conversion in a muonic atom, K^0 - \bar{K^0} and B - \bar{B} mixing, epsilon and epsilon'/ εCP- violating coefficients have been already established. By using the OPAL upper bound of the branching ratio for the B^- -> K^- K^- π^+ decay, we indicate additional constraints on the Z' couplings. We comment also on the constraints of Z' couplings coming from the b->d d \bar{s} transition. The constraint obtained here from the upper bound of the B^- -> K^- K^- π^+ decay involves a different combination of couplings than those previously presented, but is much weaker.

description: We reconsider the problem of the critical behavior of a three-dimensional $O(m)$ symmetric magnetic system in the presence of random anisotropy disorder with a generic trimodal random axis distribution. By introducing $n$ replicas to average over disorder it can be coarse-grained to a $ϕ^{4}$-theory with $m \times n$ component order parameter and five coupling constants taken in the limit of $n \to 0$. Using a field theory approach we renormalize the model to two-loop order and calculate the $β$-functions within the $\varepsilon$ expansion and directly in three dimensions. We analyze the corresponding renormalization group flows with the help of the Padé-Borel resummation technique. We show that there is no stable fixed point accessible from physical initial conditions whose existence was argued in the previous studies. This may indicate an absence of a long-range ordered phase in the presence of random anisotropy disorder with a generic random axis distribution.

description: We present a general framework for teaching 3D imagination demanding topics using commonly available hardware for virtual reality (VR). Our software allows collaborating on 3D objects, interaction and annotation in a simple and intuitive manner. Students can follow the exposition from an arbitrary, naturally chosen point of view, and they interact with the shared scene by adding annotations and using a pointing metaphore. The software allows using various VR headsets as well as opting for a traditional 3D rendering on a 2D screen. The framework has been tested in a small course on polygon mesh processing, identifying and eliminating the most serious flaws. In its current form, most of the sources of friction have been addressed and the system can be employed in a variety of teaching scenarios.

title: From Dreamer to DACAmented: Understanding the Educational Choices of Undocumented Immigrants in Texas
Creators: name: Monarrez, Tomaz
Publisher: name: The University of Texas at Austin
Year: 2017
Subjects: subject: policy brief
subject: dreamers

description: Immigration reform is one of the centerpieces of an increasingly polarized political debate in the United States. This debate has partly focused on the adjustment of status of unauthorized immigrants that have resided in the country from a young age and for extended periods of time. Institutionally, this immigrant subgroup resides in a unique limbo: on the one hand they face many institutional constraints given their lack of status – for instance, being ineligible for employment and the social safety net. On the other hand, federal law mandates public schools to serve this subgroup, and several government entities (both at the state and federal level) have recently initiated efforts to alleviate institutional constraints for them. One the key movements of this recent trend is the enactment of tuition equity reforms by state legislatures. As of 2015, eighteen states in the nation had enacted tuition equity laws granting resident tuition rates to qualifying undocumented students.1 The state of Texas was the pioneer of this movement, approving House Bill 1403 in July of 2001. The initiative came to be known as the ’Texas Dream Act’ (henceforth, TDA). It granted a large reduction in the cost of college attendance for undocumented students, moving them from out-of-state to in-state status in terms of tuition and fees. The complex institutional environment faced by the affected population, however, hinders our ability to predict the effect of this reform on education attainment on purely theoretical grounds. On the one hand, this group is forbidden from participating in the formal labor market. Thus, while the expected return to higher education for this group is difficult to assess, it is likely lower than that of natives, and may or may not be higher than the value starting to earn at an earlier age.2 On the other hand, college education may have consumption value in and of itself for undocumented immigrants, not just due to its intrinsic value but also because academic institutions have been identified as a partial safe haven from the duress of lack of immigration status once adulthood has been reached, including a reduced risk of deportation (Gonzales, 2010). Thus, the effect of tuition equity reforms on the post- secondary educational attainment of undocumented immigrant students is theoretically ambiguous, and better studied empirically.

description: As noble liquid time projection chambers grow in size their high voltage requirements increase, and detailed, reproducible studies of dielectric breakdown and the onset of electroluminescence are needed to inform their design. The Xenon Breakdown Apparatus (XeBrA) is a 5-liter cryogenic chamber built to characterize the DC high voltage breakdown behavior of liquid xenon and liquid argon. Electrodes with areas up to 33~cm$^2$ were tested while varying the cathode-anode separation from 1 to 6~mm with a voltage difference up to 75~kV. A power-law relationship between breakdown field and electrode area was observed. The breakdown behavior of liquid argon and liquid xenon within the same experimental apparatus was comparable.

description: This study examined the impact of a multi-year, large-scale professional development program on student achievement in mathematics and science. Math and science teachers at the elementary and secondary levels who participated in the professional development program were matched to a control group. Results revealed no differences in STAAR test scores between treatment and control groups for all grades and subjects except elementary students in rural areas. In rural areas, fifth grade students of teachers in the treatment group outperformed students of teachers in the control group on the STAAR Math and STAAR Science assessments. These results suggest that the large-scale professional development program is particularly beneficial for rural elementary school teachers, perhaps due to rural teachers having a greater need for the connections and resources gained by participating in the program and to elementary teachers having more flexibility in the amount of time they spend teaching math and science in their classrooms. Effect sizes for the statistically significant differences were very small. Estimates of the variance in test scores at the three hierarchical levels (students, teachers, and schools) revealed that teachers account for relatively little of the variation in students’ scores. This finding suggests that expectations that professional development programs themselves will significantly impact student achievement on standardized tests may be unrealistic. It also points to the potential value of systemic professional development programs that involve schools and school leaders in addition to training individual teachers. Although there has been strong evidence that professional development increases teachers’ knowledge and skills, which in turn leads to more effective instruction (Darling-Hammond et al., 2009), few studies have examined the direct link between professional development and student achievement, and fewer still have done so with the rigor needed to facilitate causal inferences regarding the effectiveness of professional development on student outcomes (Yoon, Duncan, Lee, Scarloss, & Shapley, 2007). Moreover, studies have provided mixed evidence for the overall effectiveness of professional development on student achievement. Some studies have found positive effects (Heller et al., 2012; McMeeking et al.,2012), null effects (Garet et al., 2008; Garet et al., 2010), or even negative effects of professional development on student outcomes (Borman, Gamoran, & Bowdon, 2008). As a result, education leaders are left without the clear guidance needed to form accurate expectations of the potential impact that different professional development programs can have on student achievement.

description: We consider a magnet with uniaxial anisotropy in an external magnetic field along the anisotropy direction, but with a field magnitude smaller than the coercive field. There are three representative magnetization configurations corresponding to three extrema of the free energy. The equilibrium and metastable configurations, which are magnetized approximately parallel and antiparallel to the applied field, respectively, both correspond to local free-energy minima. The third extremum configuration is the saddle point separating these minima. It is also called the transition state for magnetization reversal. The free-energy difference between the metastable and transition-state configurations determines the thermal stability of the magnet. However, it is difficult to determine the location of the transition state in both experiments and numerical simulations. Here it is shown that the computational Projective Dynamics method, applied to the time dependence of the total magnetization, can be used to determine the transition state. From large-scale micromagnetic simulations of a simple model of magnetic nanowires with no crystalline anisotropy, the magnetization associated with the transition state is found to be linearly dependent on temperature, and the free-energy barrier is found to be dominated by the entropic contribution at reasonable temperatures and external fields. The effect of including crystalline anisotropy is also discussed. Finally, the influence of the spin precession on the transition state is determined by comparison of the micromagnetic simulations to kinetic Monte Carlo simulations of precession-free (overdamped) dynamics.

description: Providing the opportunity for hands-on experience is crucial when teaching courses about Virtual Reality (VR) and Augmented Reality (AR). However, the workload on the educator's side for providing these opportunities might be prohibitive. In addition, other organizational challenges can arise, for example, demonstrations of VR/AR application in a course might be too time-consuming, especially if the course is attended by many students. We present the Circuit Parcours Technique to meet these challenges. Here, in a well-organized event, stations with VR/AR demonstrations are provided in parallel, and students are enlisted to prepare and conduct the demonstrations. The event is embedded in a four-phase model. In this education paper, the technique is precisely described, examples for its flexible usage in different teaching situations are provided, advantages such as time efficiency are discussed, and lessons learned are shared from our experience with using this method for more than 10 years. Moreover, learning goals are identified that can be achieved with this technique besides gaining personal experience.

We evaluate our new methodology by means of three use cases from two different universities. Our contributions include the proposed methodology, the discussion on the outcome of the use cases, the benefits and limitations of our current approach, and a reflection on the open problems and noteworthy gaps to improve the current pedagogical techniques to teach visualization and promote critical thinking. Our findings show extensive benefits from the use of our approach in terms of the number of transferable skills to students, educational resources for educators, and additional feedback for research opportunities to the visualization community.

Teaching 3D Computer Animation to Non-programming Experts
Creators: name: Casas, Dan
Publisher: name: The Eurographics Association
Year: 2021

description: This paper describes a Computer Animation course aimed at novice Computer Science and Engineering students with minimal programming skills. We observe that students enrolled in Computer Graphics (and related) undergraduate degrees usually face a Computer Animation subject early in their programs, sometimes even before they develop strong software development and programming skills. This causes that assignments and tasks where students should focus on the Computer Animation concepts, end up in frustration and massive efforts to just get over-complicated developing frameworks running. Instead, we propose a Computer Animation course based on small MATLAB tasks that covers a large range of topics and it is adapted to students with minimal programming skills. For each topic, we provide a brief theoretical summary and links to fundamental literature, as well as a set of hands-on tasks with the necessary source code to get started. A user study shows that students who took this course were able to better focus on the fundamental concepts of the subject, circumventing the need to learn advanced programming skills. Course material is available on a public GitHub repository, and solutions are provided upon request from course tutors.

Dabei zeigen sich insbesondere zwei Spannungsfelder auf. Erstens beeinflusst die jeweilige Organisationform und -kultur, wie eine Verhandlung strukturiert und definiert wird. Zweitens zeigen sich Unterschiede zwischen Experten und Expertinnen bei der Definition einer Verhandlung und was als positives Verhandlungserlebnis wahrgenommen wird. Daraus lässt sich die zentrale Herausforderung ableiten, diese Unterschiede im Rahmen der inhaltlichen, konzeptuellen und strukturellen Konzeption bestehender sowie neuer Weiterbildungsangebote abzubilden, zu diskutieren und erfahrbar zu machen. Ausserdem wurde sichtbar, dass eine nachhaltige Weiterbildung im Bereich Verhandlung auf eine «hybride» Struktur setzt, die die Vermittlung theoretischer Inhalte digital ermöglicht, während die Anwendung und Reflexion des gelernten im Rahmen eines aktiven Austausches mit ExpertInnen und anderen Studierenden durchgeführt wird.

Faced with this challenge we experimented with a novel supplement to standard video lecturing to teach our normal face-to-face large undergraduate graphics class (close to 150 students). This supplement involved using Observable notebook, and turned out to be very effective for remote teaching. We wish to continue its use even after college life turns normal, and would like to share our experience with the community and encourage such use for teaching introductory computer graphics courses.

description: Epistemic Logic Programs (ELPs), an extension of Answer Set Programming (ASP) with epistemic operators, have received renewed attention from the research community in recent years. Classically, evaluating an ELP yields a set of world views, with each being a set of answer sets. In this paper, we propose an alternative definition of world views that represents them as three-valued assignments, where each atom can be either always true, always false, or neither. Based on several examples, we show that this definition is natural and intuitive. We also investigate relevant computational properties of these new semantics, and explore how other notions, like strong equivalence, are affected.

description: Every year, colleges refer more than a million students they deem underprepared for college-level mathematics coursework to sequences of one or more developmental math courses. Most of these students linger in developmental math courses for years, either because they are placed into longer sequences of courses, struggle to pass these courses, or both. Developmental and college-level math requirements are both significant barriers for many students, regardless of major (Bailey, Jeong, & Cho, 2010; Chen, 2016). In this study, we examined one strategy for dev-ed math reform, the Dana Center Math Pathways (DCMP) model. The DCMP model encouraged students to enroll in a college-level math course best suited to their field of interest and, at the time of inquiry, used a compression approach, condensing sequences of two or more developmental courses into a shorter, accelerated prerequisite course that covers the same content in a single semester. Among two cohorts of students who enrolled in developmental math courses in fall 2015 and fall 2016, we compared key early outcomes of those enrolled in DCMP developmental courses with peers enrolled primarily in traditional developmental math courses. We find evidence of greater enrollment and pass rates in introductory college-level math courses among the DCMP enrollees as early as one semester after developmental enrollment.

description: In this paper we study the time evolution of a class of two-level systems driven by periodic fields in terms of new convergent perturbative expansions for the associated propagator U(t). The main virtue of these expansions is that they do not contain secular terms, leading to a very convenient method for quantitatively studying the long-time behaviour of that systems. We present a complete description of an algorithm to numerically compute the perturbative expansions. In particular, we applied the algorithm to study the case of an ac-dc field (monochromatic interaction), exploring various situations and showing results on (time-dependent) observable quantities, like transition probabilities. For a simple ac field, we analised particular situations where an approximate effect of dynamical localisation is exhibited by the driven system. The accuracy of our calculations was tested measuring the unitarity of the propagator U(t), resulting in very small deviations, even for very long times compared to the cycle of the driving field.

description: At the Large Hadron Collider (LHC), several far detectors such as FASER and MATHUSLA have been proposed to target the long-lived particles (LLPs) featured with displaced vertices. Naturally one question arises as to the feasibility of installing similar far detectors at future lepton colliders like the CEPC and FCC-ee. Because of the different kinematics of final state particles and the freedom to locate both the experiment hall and the detectors, the future lepton collider with an additional far detector may play a unique role in searching for LLPs. In this study, we consider various locations and designs of far detectors at future $e^- e^+$ colliders and investigate their potentials for discovering LLPs in the physics scenarios including exotic Higgs decays, heavy neutral leptons, and the lightest neutralinos. Our analyses show that the kinematical distinctions between the lepton and hadron colliders render the optimal positions of far detectors lying at the direction perpendicular to the collider beams at future $e^- e^+$ colliders, in contrast to the LHC where a boost in the forward direction can be exploited. We also find that when searching for LLPs, such new experiments with far detectors at future lepton colliders may extend and complement the sensitivity reaches of the experiments at the future lepton colliders with usual near detectors, and the present and future experiments at the LHC. In particular, we find that, for the theory models considered in this study, a MATHUSLA-sized far detector would give a modest improvement compared to the case with a near detector only at future lepton colliders.

description: I study a relativistic open string coupling through its endpoints to a plane wave with arbitrary temporal profile. The string's transverse oscillations respond linearly to the external field. This makes it possible to solve the classical equations, and to calculate the quantum-mechanical S-matrix in closed form. I analyze the dynamics of the string as the characteristic frequency and duration of the pulse are continuously varied. I derive, in particular, the multipole expansion in the adiabatic limit of very long wavelengths, and discuss also more violent phenomena such as shock waves, cusps and null brane intersections. Apart from their relevance to the study of time-dependence in superstring theory, these results could have other applications, such as the teleportation of gravitational wave bursts by cosmic strings.

description: Die Befragung von 1929 volljährigen Personen in der Schweiz im Zeitraum vom 17. - 26. April 2020 legt nahe, dass eine grosse Mehrheit der Bevölkerung auf jeden Fall oder wahrscheinlich beabsichtigt, a) eine App zur Kontaktnachverfolgung von SARS-CoV-2 zu installieren, b) Infektionen in der App zu melden und c) der Aufforderung der App nach Kontaktreduktion bzw. häuslicher Quarantäne nachzukommen. Als Grundlage der Befragung diente das Szenario einer «anonymen» App zur freiwilligen Kontaktnachverfolgung via Bluetooth (analog zu DP-3T). Die App erfasst keine Standort- und Bewegungsdaten, sondern registriert lediglich andere App-Nutzer in der näheren Umgebung. Gründe für die Nutzung der App sind vor allem Verantwortungsbewusstsein gegenüber der Allgemeinheit (73% der Befragten), der Schutz der eigenen Familie und der eigenen Freunde (67%) und ein Beitrag zur Reduktion der Todesfälle unter älteren Menschen und Menschen mit Vorerkrankungen (50%). Die Befragten führen ebenfalls Gründe an, die für sie gegen die Nutzung einer App sprechen würden. Bei 40% besteht das Bedenken, dass der Staat die App als Vorwand für die stärkere Überwachung während oder nach der Pandemie nutzen könnte. 39% äussern das Bedenken, dass die App nicht funktioniert (z.B. Fehlalarme). Die Zusammensetzung der Befragten entspricht nach Alter, Geschlecht und Grossregionen der Struktur der volljährigen Schweizer Bevölkerung.
