description: Educative platforms are at the heart of the development of online education. They can not only be reduced to technological aspects. Underlying models impact teaching and learning from the preparing of lessons to the learning sessions. Research related to these platforms are numerous and their stakes are important. For these reasons, we launched a call to a special issue on "Designs and uses of educative platforms" An educative platform is a computer system designed to automate various functions relating to the organization of the course, to the management of their content, to the monitoring of learners and supervision of persons in charge of various formations (Office de la langue française, 2005). So educative platforms are Learning Management Systems (LMS) which are specific to education contexts.

description: Adding a second scalar doublet (eta^+,eta^0) and three neutral singlet fermions N_{1,2,3} to the Standard Model of particle interactions with a new Z_2 symmetry, it has been shown that eta^0_R or eta^0_I is a good dark-matter candidate and seesaw neutrino masses are generated radiatively. A minimal extension of this new idea is proposed to allow for its SU(5) completion. Supersymmetric unification is then possible, and leptoquarks of a special kind are predicted at the TeV scale.

The Cunning Little Vixen: A Folktale Illustrated On Stage
Creators: name: Reid, Mikayla
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: This thesis paper reflects upon the costume design process taken by Mikayla Reid to explore how color choice and application within designs can help create storybook characters off the page and onto the stage. This concept is explored through the costume designs for the opera The Cunning Little Vixen, a production theoretically staged at the Alice Busch Opera Theater for the Glimmerglass Festival in New York. The paper discusses Reid’s attempt to create designs that still feel like watercolor illustrations, even when realized in physical garments. It follows her process as she tests different dye techniques in search for what produces the most effective color application. This paper also breaks down each step taken while constructing the main character, the Vixen, through the build, fittings, and color application.

description: Energy plays a fundamental role in both manufacturing and services, and natural gas is quickly becoming a key energy source worldwide. Facilitating this emergence is the expanding network of ocean-going vessels that enable the matching of natural gas supply and demand on a global scale by transporting it in the form of liquified natural gas (LNG) for eventual regasification at its destination. Until very recently only one type of technology has been available for transporting and regasifying LNG: Conventional LNG vessels and land based LNG regasification. It is now possible to transport and regasify LNG onboard special LNG vessels. Companies such as Excelerate Energy and Höegh LNG are currently developing LNG supply chains based on this new technology. Motivated by this recent development we engaged executives at Excelerate Energy to develop and apply to data an integrated analytic framework to compare these incumbent and emerging technologies. Our analysis brings to light basic principles delineating when to deploy each technology and how to configure the emerging technology. Some of our findings challenge conventional wisdom on the role to be played by the emerging technology; others provide answers to open questions faced by companies currently engaged in the commercial deployment of this technology. In addition, our integrated analytic framework has potential relevance for the evaluation of new technologies beyond this specfiic application.
Teacher's Discipline Practices and Race: The Effect of "Fair" and "Unfair" Discipline on Black and White Student's Perceptions and Behaviors
Creators: name: Rivera-Rodriguez, Adrian
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: Negative stereotypes characterizing Black males as prone to causing trouble can lead teachers to punish misbehaving Black boys more harshly than their White peers. Awareness of unfair discipline practices has been linked to future disciplinary infractions among Black males, hinting that some Black males may engage in defiant behavior in response to unfair discipline. Despite the documented links between awareness of unfair discipline and future disciplinary infractions among Black males, questions remain as to (1) the types of disciplinary practices from teachers that students perceive as fair and unfair; (2) the psychological processes that motivate Black male behavior after experiencing unfair discipline; and (3) whether these psychological processes differ from those that motivate White male behavior. Across three studies, the present research explores these questions by asking Black and White men to recall the type of treatment from teachers that they perceived as fair and unfair (Study 2), as well as how they would have perceived and responded to different scenarios describing instances of either fair and unfair discipline from teachers in middle and high school (Studies 1 and 3). Qualitative results from Study 2 highlights negotiable (i.e., a collaborative effort between a teacher and their pupil to discuss and analyze how and why a particular situation arose from all perspectives) and non-negotiable (i.e., teacher ignores the pupil’s explanation for the infraction) discipline as two contrasting practices that men viewed as fair and unfair, respectively. Quantitative results from Study 3 indicated that unfair (non-negotiable), compared to fair (negotiable) discipline from teachers triggered negative emotions associated with reputation threat (i.e., embarrassment, shame, anger, and sadness), which in turn predicted future defiant behavior among both Black and White men. Furthermore, the extent to which unfair discipline from teachers was attributed to racial bias also predicted greater negative emotions and defiant behavior for Black, but not White, men. Together, these findings shed light on a process through which unfair disciplinary practices may motivate defiance from students via negative emotions among both Black and White students; as well as the unique role that race bias attributions have on Black students’ perceptions of unfair discipline.

description: We introduce the `Fourier transform' F_C on the isotropic cone C associated to an indefinite quadratic form of signature (n_1,n_2) on R^n (n=n_1+n_2: even). This transform is in some sense the unique and natural unitary operator on L^2(C), as is the case with the Euclidean Fourier transform. Inspired by recent developments of algebraic representation theory of reductive groups, we shed new light on classical analysis on the one hand, and give the global formulas for the L^2-model of the minimal representation of the simple Lie group G=O(n_1+1,n_2+1) on the other hand. The transform F_C expands functions on C into joint eigenfunctions of the n commuting, self-adjoint, second order differential operators. We decompose F_C into the singular Radon transform and the Mellin--Barnes integral, find its distribution kernel, and establish the inversion and the Plancherel formula. F_C reduces to the Hankel transform if G is O(n,2) or O(3,3). The unitary operator F_C together with the simple action of the conformal transformation group generates the minimal representation of the indefinite orthogonal group G. Various different models of the same representation have been constructed by Kazhdan, Kostant, Binegar-Zierau, Gross-Wallach, Zhu-Huang, Torasso, Brylinski, and Kobayashi-Orsted, and others. Among them, our model built on L^2(C) generalizes the classic Schrodinger model of the Weil representation. Yet another motif is special functions. Large group symmetries in the minimal representation yield functional equations of various special functions. We find explicit K-finite vectors on L^2(C), and give a new proof of the Plancherel formula for Meijer's G-transforms.

description: We consider the decidability of state-to-state reachability in linear time-invariant control systems over discrete time. We analyse this problem with respect to the allowable control sets, which in general are assumed to be defined by boolean combinations of linear inequalities. Decidability of the version of the reachability problem in which control sets are affine subspaces of $\mathbb{R}^n$ is a fundamental result in control theory. Our first result is that reachability is undecidable if the set of controls is a finite union of affine subspaces. We also consider versions of the reachability problem in which (i)~the set of controls consists of a single affine subspace together with the origin and (ii)~the set of controls is a convex polytope. In these two cases we respectively show that the reachability problem is as hard as Skolem's Problem and the Positivity Problem for linear recurrence sequences (whose decidability has been open for several decades). Our main contribution is to show decidability of a version of the reachability problem in which control sets are convex polytopes, under certain spectral assumptions on the transition matrix.

The high temperatures in the center of the sun broaden the line asymmetrically, FWHM = 1.6~keV, and cause an average energy shift of 1.3~keV. The width of the $^7$Be neutrino line should be taken into account in calculations of vacuum neutrino oscillations.

Tall Timber in Denver: An Exploration of New Forms in Large Scale Timber Architecture
Creators: name: Weuling, Andrew P
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: Wood has been utilized by humans for thousands of years in the construction of our built environment. More recently, our expanded understanding of the material and the advancement of engineered wood have allowed us to use wood like never before. Concrete and steel, however, have emerged as the main materials used in large scale construction in the late 19th and 20th Centuries. As we are battling and searching for solutions to climate change, the importance of wood in large scale construction has increased as not only is its carbon intensity is lower than steel and concrete, but its existence stems from sequestered carbon. Yet as timber finds its way into large-scale projects, the forms it takes resemble those of concrete construction. Although this form is functional, it does not take full advantage of its capabilities or mitigate the weaknesses of wood.
This thesis is concerned with exploring new options for mass timber, finding forms more appropriate to wood’s mechanical and aesthetic properties. Research began with precedent studies of existing mass timber structures to see which strategies would be useful in the project. Next a theoretical project was undertaken to design an 18-story timber-based high rise in Denver, Colorado. The design uses a variety of Engineered Wood Products (EWP) in the most effective and efficient way.
The findings of this study have shown that wood, being an isotropic material, prefers to have forces run parallel to its grain. Combining multiple types of engineered wood arranged to create forces traveling parallel to their fiber grain direction created a system that was efficient, strong, and architecturally effective. The design also works to avoid subjecting wood to forces perpendicular to its wood grain, thus avoiding its weaknesses. Finally, the design uses common, stock, engineered lumber products to make the project more economical. It produced a high rise design that serves as a highly desirable model for future projects across the United States and world. This technology will not be limited to high rises and can be used in a plethora of large-scale building types. Broader implementation of this technology will help to decrease our species’ carbon footprint as our population expands and builds. More material efficient structural solutions will encourage wider spread implementation and their aesthetic qualities will increase their desirability by private and government investors alike.

description: We introduce a notion of resultant of two meromorphic functions on a compact Riemann surface and demonstrate its usefulness in several respects. For example, we exhibit several integral formulas for the resultant, relate it to potential theory and give explicit formulas for the algebraic dependence between two meromorphic functions on a compact Riemann surface. As a particular application, the exponential transform of a quadrature domain in the complex plane is expressed in terms of the resultant of two meromorphic functions on the Schottky double of the domain.

Beautiful "Looks" Created by Women: New Aesthetics on Makeup for Overturning the Traditional Japanese Beauty
Creators: name: Yoshikawa, Yurina
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: In this thesis I focus on comparing the styles of beauty or “looks” that women have created for themselves, as well as concepts of traditional beauty. By doing so, this thesis will clarify how women try to change traditional beauty concepts and express themselves. As anyone who has watched TV in Japan has noticed, Japan has stereotyped aesthetic values of women that mass media such as magazines or TV dramas have created and disseminated. Pictures of beautiful women (bijinga 美人画) and beauty pageants are just two examples. In Japan, women having black hair, white skin, almond-shaped eyes, and well-defined noses are considered beautiful, and this aesthetic has not changed much since the Heian period (794-1185). After the work of Takehisa Yumeji (1884-1934), whose pictures created the foundation of kawaii culture in the Taishō period (1912-1926), women have adopted this new aesthetic category in order to get around the fixed aesthetics of the bijin look. In other words, the start of kawaii culture is one of the turning points for women to evade a monolithic image of what is considered beautiful. However, as kawaii culture spread across the world due to the popularity of manga and anime, the notion of kawaii also began to be fixed by the mass media, becoming as rigid as the notion of bijin. For example, Japanese idols from the Shōwa period (1926-1989) through the Heisei and Reiwa all look alike by design. Many idols have bangs, natural black or dark brown hair, and flat-shaped eyebrows which are attractive to men. To overturn this tendency, some women have created new kinds of makeup styles to express their own version kawaii aesthetics. Ganguro, yamamba, or “gal” makeup were all created by women and popular among young women. In general society—particularly men—did not accept these makeup styles as aesthetically beautiful; the public regarded these looks as not kawaii but rather ugly (busaikuブサイク). However, even though society found looks ugly, this kind of makeup nevertheless became extremely popular among girls and women in their 10s and 20s who regarded such looks as kawaii and trendy. This aesthetic can be seen as what happens when women get around fixed notions of beauty by adopting and transforming the idea and look of kawaii. In this thesis I discuss the development of the kawaii aesthetic and how it becomes a way for women to break out of the tyranny of bijin. I look at a trend of new bijinga and talk about how women are trying to break away from the traditional notion of bijin. Using a collection of contemporary bijinga, I examine how actresses are fighting to do their own makeup for their films, TV programs, or dramas; in particular, actresses Ishihara Satomi and Nanao try to express their own beauty by creating the characters’ looks themselves. In this respect, the characters are original styles of beauty created by these women.

description: Theoretical studies of quantum phase transitions have suggested critical points with higher symmetries than those of the underlying Hamiltonian. Here we demonstrate a surprising emergent symmetry of the coexistence state at a strongly discontinuous phase transition between two ordered ground states. We present a quantum Monte Carlo study of a two-dimensional $S=1/2$ quantum magnet hosting the antiferromagnetic (AFM) and plaquette-singlet solid (PSS) states recently detected in SrCu$_2$(BO$_3$)$_2$. We observe that the O(3) symmetric AFM order and the Z$_2$ symmetric PSS order form an O(4) vector at the transition. The control parameter $g$ (a coupling ratio) rotates the vector between the AFM and PSS sectors and there are no energy barriers between the two at the transition point $g_c$. This phenomenon may be observable in SrCu$_2$(BO$_3$)$_2$.

description: Current theoretical arguments highlight the negative implications of cohesion in a network neighborhood for relationships with outsiders. We present argument and evidence illustrating the importance of knowledge overlap inside a neighborhood in moderating the negative internal cohesion effect. We analyzed the tendency for individuals to initiate and sustain knowledge transfer relationships in an online technical forum. Empirical results indicated that as cohesion in a neighborhood increased each member was less likely to initiate and sustain external knowledge transfer relationships. However, the magnitude of negative effect that cohesion had on external knowledge transfer relationships declined as knowledge overlap in the neighborhood increased. Our research findings clarify one condition under which increasing cohesion in a network neighborhood can be expected to undermine external knowledge transfer relationships, and therefore the extent to which the benefits created by cohesion in a neighborhood will come at the expense of relationships that provide access to resources outside the neighborhood.

description: As a starting point, we state some relevant geometrical properties enjoyed by the cosmological horizon of a certain class of Friedmann-Robertson-Walker backgrounds. Those properties are generalised to a larger class of expanding spacetimes $M$ admitting a geodesically complete cosmological horizon $\scrim$ common to all co-moving observers. This structure is later exploited in order to recast, in a cosmological background, some recent results for a linear scalar quantum field theory in spacetimes asymptotically flat at null infinity. Under suitable hypotheses on $M$, encompassing both the cosmological de Sitter background and a large class of other FRW spacetimes, the algebra of observables for a Klein-Gordon field is mapped into a subalgebra of the algebra of observables $\cW(\scrim)$ constructed on the cosmological horizon. There is exactly one pure quasifree state $λ$ on $\cW(\scrim)$ which fulfils a suitable energy-positivity condition with respect to a generator related with the cosmological time displacements. Furthermore $λ$ induces a preferred physically meaningful quantum state $λ_M$ for the quantum theory in the bulk. If $M$ admits a timelike Killing generator preserving $\scrim$, then the associated self-adjoint generator in the GNS representation of $λ_M$ has positive spectrum (i.e. energy). Moreover $λ_M$ turns out to be invariant under every symmetry of the bulk metric which preserves the cosmological horizon. In the case of an expanding de Sitter spacetime, $λ_M$ coincides with the Euclidean (Bunch-Davies) vacuum state, hence being Hadamard in this case. Remarks on the validity of the Hadamard property for $λ_M$ in more general spacetimes are presented.

description: We analyze the implications of the infrared quasi fixed point solution for the top quark mass in the Minimal Supersymmetric Standard Model. This solution could explain in a natural way the relatively large value of the top quark mass and, if confirmed experimentally, may be suggestive of the onset of nonperturbative physics at very high energy scales. In the framework of grand unification, the expected bottom quark - tau lepton Yukawa coupling unification is very sensitive to the fixed point structure of the top quark mass. For the presently allowed values of the electroweak parameters and the bottom quark mass, the Yukawa coupling unification implies that the top quark mass must be within ten percent of its fixed point values.

description: We present theoretical study of shot noise in single wall metallic carbon nanotubes weakly coupled to either nonmagnetic or ferromagnetic leads. Using the real-time diagrammatic technique, we calculate the current, Fano factor and tunnel magnetoresistance in the sequential tunneling regime. It is shown that the differential conductance displays characteristic four-fold periodicity, indicating single-electron charging. Such a periodicity is also visible in tunnel magnetoresistance of the system as well as in the Fano factor. The present studies elucidate the impact of ferromagnetic (vs. nonmagnetic) contacts on the transport characteristics under consideration.

description: Commodities, ranging from natural gas to memory chips, can be procured both by trading on the date in spot markets and in advance in forward markets. Transaction costs, such as brokerage fees, are typically higher in spot markets than in forward markets. Moreover, the forecast of a ¯rm's commodity requirement (demand) for a given future date typically changes in an uncertain fashion over time. Thus, although the dynamics of forward and spot prices are notoriously uncertain, firms that procure commodities face the dilemma of choosing between early and possibly less expensive commitments with residual demand uncertainty and late and possibly more expensive sourcing of the exact amount needed. We investigate this issue by developing and analyzing a model of commodity procurement for a single future date. Our model generalizes models available in the real options and operations management literature, by simultaneously considering correlated demand forecast and forward price updates in a setting characterized by multiple forward transactions and a single spot transaction. We derive the structure of the optimal procurement policy and discuss its computation in cases of practical interest. In a numerical study, based on applying our model to natural gas data, we offer managerial insights on the effects that demand forecast and forward price updates, both in isolation and combined, have on the value of a firm's procurement policy. We also assess the sensitivities of these effects to parameters of interest and the potential managerial relevance of the combined effect. Our model and results have significance beyond the specific application.
Developing Lesson Plans for Teaching Spatial Data Management in Academic Libraries through a Lens of Popular Culture

description: Understanding data management in spatial data science is fundamentally important when ensuring a project’s data is appropriately collected, analyzed, stored, and communicated. However, these concepts are often introduced to learners through compliance (i.e., we do this because we are required to or it is the right thing to do), and as a result can mean learning experiences around spatial data management are viewed less than enthusiastically. Academic libraries are places where engaging learning experiences around spatial data management can be explored and implemented through unique pedagogical techniques. For example, activities teaching spatial data management in academic libraries through a popular culture lens can make these topics more approachable and reduce learning barriers. In this paper, I present three lesson plans for academic librarians which approach teaching spatial data management through popular culture. The following concepts are represented: (1) understanding spatial metadata through Dungeons & Dragons; (2) learning to write good documentation through drawing Pokémon; and (3) developing good file naming habits with 1980s album covers. Alongside the lesson plans, I provide a narrative outlining why popular culture pedagogy is a useful technique to spatial data management education to increase the inclusivity and engagement around geospatial learning experiences in academic libraries.
The associated lesson plans are also available on KiltHub at https://doi.org/10.1184/R1/13350428.v1.

High-frequency spicule oscillations generated via mode conversion

description: Spicule oscillations involve high-frequency components with a typical period approximately corresponding to $40-50$ s. The typical time scale of the photospheric oscillation is a few minutes, and thus, the origin of this high-frequency component is not trivial. In this study, a one-dimensional numerical simulation is performed to demonstrate that the observed spicule oscillations originate from longitudinal-to-transverse mode conversion that occurs around the equipartition layer in the chromosphere. Calculations are conducted in a self-consistent manner with the exception of additional heating to maintain coronal temperature. The analyses indicate the following features: (1) mode conversion efficiently excites high-frequency transverse waves; (2) the typical period of the high-frequency waves corresponds to the sound-crossing time of the mode conversion region; and (3) simulated root-mean-square velocity of the high-frequency component is consistent with the observed value. These results indicate that the observation of spicule oscillation provides direct evidence of mode conversion in the chromosphere.

description: On traversing materials with absorbing dyes, weak optical beams develop a Beer (exponential) profile, while intense beams develop a spatially initially linear and then finally an exponential profile. This anomalous, deep penetration due to photo-bleaching of surface layers is important for heavy dye-loading and intense beams, for instance in photo-actuation. We address the problem of the evolution in time from initial Beer's Law to deeply penetrating optical profiles in dyes. Our solution of the coupled, non-linear, partial differential equations governing the spatio-temporal decay of the Poynting flux and the non-linear dynamics of the \textit{trans-cis} conversion is applicable to general systems of photo-active molecules under intense irradiation, for instance in biology, in spectroscopy and in opto-mechanical devices.

description: This is an extremely interesting paper. The main point of the paper is to test some alternative assumption about savings within the context of money demand equations. The work is at an early stage at this time, but the results look to be of some interest. The idea is a good one and deserves to be pursued more thoroughly than the authors have yet done.
Violation Of The $ΔI = 1/2$ Rule In $D \to ππ$ Decays

description: A strong violation of the $\displaystyle{ΔI = {1\over 2}} $ rule has experimentally been found in the $\displaystyle{D \to ππ}$ decays [1]. In this letter we will show that the order of magnitude of this violation can be understood in terms of the pure quantum chromo dynamics corrections to the weak interactions.

Cluster-induced deagglomeration in dilute gravity-driven gas-solid flows of cohesive grains

description: Clustering is often presumed to lead to enhanced agglomeration between cohesive grains due to the reduced relative velocities of particles within a cluster. Our discrete-particle simulations on gravity-driven, gas-solid flows of cohesive grains exhibit the opposite trend, revealing a new mechanism we coin "cluster-induced deagglomeration." Specifically, we examine relatively dilute gas-solid flows and isolate agglomerates of cohesive origin from overall heterogeneities in the system, i.e., agglomerates of cohesive origin and clusters of hydrodynamic origin. We observe enhanced clustering with an increasing system size (as is the norm for noncohesive systems) as well as reduced agglomeration. The reduced agglomeration is traced to the increased collisional impact velocities of particles at the surface of a cluster; i.e., higher levels of clustering lead to larger relative velocities between the clustered and nonclustered regions, thereby serving as an additional source of granular temperature. This physical picture is further evidenced by a theoretical model based on a balance between the generation and breakage rates of agglomerates. Finally, cluster-induced deagglomeration also provides an explanation for a surprising saturation of agglomeration levels in gravity-driven, gas-solid systems with increasing levels of cohesion, as opposed to the monotonically increasing behavior seen in free-evolving or driven granular systems in the absence of gravity. Namely, higher cohesion leads to more energy dissipation, which is associated with competing effects: enhanced agglomeration and enhanced clustering, the latter of which results in more cluster-induced deagglomeration.

description: Background In native environments plants frequently experience simultaneous or sequential unfavourable abiotic and biotic stresses. The plant’s response to combined stresses is usually not the sum of the individual responses. Here we investigated the impact of cold on plant defense against subsequent herbivory by a generalist and specialist insect. Results We determined transcriptional responses of Arabidopsis thaliana to low temperature stress (4 °C) and subsequent larval feeding damage by the lepidopteran herbivores Mamestra brassicae (generalist), Pieris brassicae (specialist) or artificial wounding. Furthermore, we compared the performance of larvae feeding upon cold-experienced or untreated plants. Prior experience of cold strongly affected the plant’s transcriptional anti-herbivore and wounding response. Feeding by P. brassicae, M. brassicae and artificial wounding induced transcriptional changes of 1975, 1695, and 2239 genes, respectively. Of these, 125, 360, and 681 genes were differentially regulated when cold preceded the tissue damage. Overall, prior experience of cold mostly reduced the transcriptional response of genes to damage. The percentage of damage-responsive genes, which showed attenuated transcriptional regulation when cold preceded the tissue damage, was highest in M. brassicae damaged plants (98%), intermediate in artificially damaged plants (89%), and lowest in P. brassicae damaged plants (69%). Consistently, the generalist M. brassicae performed better on cold-treated than on untreated plants, whereas the performance of the specialist P. brassicae did not differ. Conclusions The transcriptional defense response of Arabidopsis leaves to feeding by herbivorous insects and artificial wounding is attenuated by a prior exposure of the plant to cold. This attenuation correlates with improved performance of the generalist herbivore M. brassicae, but not the specialist P. brassicae, a herbivore of the same feeding guild.
title: Donaldson–Thomas invariants of threefold flops
Creators: name: van Garderen, Ogier (Okke)
Publisher: name: University of Glasgow

description: This thesis is about a class of complex algebraic threefolds known as flops, which are an important part of the Minimal Model Program in birational geometry. Threefold flops are commonly studied via their enumerative invariants, and here we focus on one such type of invariant: refined Donaldson–Thomas invariants. We develop theoretical aspects of refined Donaldson–Thomas theory for threefold flops, which allow us to understand their stability conditions and cyclic A∞-deformation theory. With these new methods, we are able to sidestep common computational barriers in the field and fully determine the Donaldson–Thomas invariants for an infinite family of flops, which includes many new examples. Our results show that a refined version of the strong-rationality conjecture of Pandharipande–Thomas holds in this setting, and also that refined Donaldson–Thomas invariants are not sufficiently fine to determine flops. Where possible we work motivically, computing invariants in the Grothendieck ring of varieties, but we also produce Hodge theoretic realisations of the invariants.
