description: We introduce a new product for permutation groups. It takes as input two permutation groups, M and N, and produces an infinite group M [X] N which carries many of the permutational properties of M. Under mild conditions on M and N the group M [X] N is simple. As a permutational product, its most significant property is the following: M [X] N is primitive if and only if M is primitive but not regular, and N is transitive. Despite this remarkable similarity with the wreath product in product action, M [X] N and M Wr N are thoroughly dissimilar. The product provides a general way to build exotic examples of non-discrete, simple, totally disconnected, locally compact, compactly generated topological groups from discrete groups. We use this to solve a well-known open problem from topological group theory, by obtaining the first construction of uncountably many pairwise non-isomorphic simple topological groups that are totally disconnected, locally compact, compactly generated and non-discrete. The groups we construct all contain the same compact open subgroup. To build the product, we describe a group U(M,N) that acts on an edge-transitive biregular tree T. This group has a natural universal property and is analogous to the iconic universal group construction of M. Burger and S. Mozes for locally finite regular trees.

This is the first proof (independent of the 4 Color Theorem) that there exists a constant $k<5$ such that every planar $G$ has fractional chromatic number at most $k$.

description: The polynomial $X^{3}-X-1$ has a unique positive root known as plastic number, which is denoted by $ρ$ and is approximately equal to $1.32471795$. In this note we study the zeroes of the generalized polynomial $X^{k}-\sum_{j=0}^{k-2}X^{j}$ for $k\geq 3$ and prove that its unique positive root $λ_{k}$ tends to the golden ratio $ϕ=\frac{1+\sqrt{5}}{2}$ as $k \to \infty$. We also derive bounds on $λ_{k}$ in terms of Fibonacci numbers.

title: An Insight into Higher Education Teachers’ Perceptions During Emergency-Remote-Teaching Through a Networked Learning Lens
title: A Phenomenographically-Informed Inquiry

Creators: name: Acuyo Cespedes, Alex

description: Higher education has long been experiencing a shift towards digitization, as teachers have grappled with the challenges of incorporating technology into various aspects of their role. During the recent Covid19 emergency-remote-teaching period, these educators were forced online at short notice and with little more than their personal learning networks to rely on. This investigation thus targets how teachers perceived and used networked learning during this turbulent remote working period, in order to identify lessons that can be taken forward to facilitate their roles in an increasingly digitized work environment. Literature gaps in the fields of networked learning and emergency-remote-teaching can be found in terms of in-depth qualitative studies that specifically target teachers’ perspectives. There is also a relatively modest amount of work targeting informal approaches to professional development throughout the emergency-remote-teaching period. A phenomenographically-informed approach is adopted as a methodological framework due to its prioritization of variation across an individual’s perception. The investigation reveals four outcome spaces with multiple description categories within each. These outcome spaces are structured in the discussion chapter with the guidance of additional literature. This reveals that teachers generally perceive networks as useful tools through which a sense of community belonging can ultimately be developed online, while the most notable challenge relates to the feeling of seclusion that networked learning can induce. In terms of networked behaviours, teachers identify the exchange of personal feelings as the most sophisticated use of their connections to people, as well as the tailoring of a bespoke online resource depository. The prevalence of connections to people over online resources is identified as a key conclusion, as is the tension between multiple weaker ties versus fewer stronger ones within an individual’s networks. The willingness and ability of teachers to stretch the user of their networks to more distant and less easy-to-access connections is also considered. Institutions should provide scaffolding to encourage networked practices among teachers in a manner that promotes the gradual transition away from traditional one-off professional development events and towards collaborative social learning. Future studies should target the longer-term implications of networked learning in a post emergency-remote-teaching period context.

description: Dominant herbivores, like leafcutter ants, have a strong impact on the ecosystems they inhabit. Understanding which factors regulate their foraging rates is crucial for understanding ecosystem dynamics. In desert habitats, environmental factors, such as temperature, play a major role in regulating ants' behavior. We studied the role of ground temperature in regulating daily and seasonal activity patterns of two coexisting leafcutters ant species, Acromyrmex lobicornis (Emery, 1888) and A. striatus (Roger, 1863), in the Monte desert of Argentina. We measured the variations in activity levels and soil temperature every two hours throughout the day in colonies of both species every season for two consecutive years. Temperature was a good predictor of both the timing of colony activation (the onset and end of their daily foraging activities) and foraging intensity (the number of workers devoted to foraging tasks). However, temperature affected each species differently: Acromyrmex lobicornis foraged at lower temperatures (10 - 35 °C) than A. striatus (27 - 45 °C). Our results suggest that these two species have different thermal tolerance ranges that result in temporally separated foraging activities. We suggest that interference competition may have driven this temperature and temporal specialization in these two sympatric species, given their similar sizes and diets. Field observations of activity vs. temperature in allopatry, and behavioral tests in controlled conditions should provide further evidence to test this hypothesis

If absorption at 0 is certain, we show that there exists a quasistationary distribution as soon as the spectrum of the generator is strictly positive. This complements results of Collet et al. (Ann. Probab. 2009) and Kolb and Steinsaltz (Ann. Probab. 2012) for $0$ being a regular boundary point and extends results by Collet et al. (Ann. Probab. 2009) on singular diffusions.

description: Mound building wood ants (genus Formica s. str.) for sure exemplify a pinnacle of social organisation and ecological impact amongst ants in the northern hemisphere. They may reach immensely large (super-)colony sizes which can only be tied together by sophisticated means of communication and nestmate recognition. Wood ants are highly important predators and provide multiple ecosystem functions. At the same time, in many parts of their distributional range, these fascinating ants are under pressure through anthropogenic influences that let their habitats deteriorate. Much research has been done, and is ongoing worldwide, on wood ants. Yet, the results tend…
Pleometrotic colony foundation in the ant Crematogaster scutellaris (Hymenoptera: Formicidae): better be alone than in bad company

description: In this study, we investigated whether pleometrosis occurs in Crematogaster scutellaris (Olivier, 1792) and which advantages it may provide. A survey of C. scutellaris queens in aphid galls revealed that 19% of the occupied galls contained two or more queens (max. five). Moreover, the observed distribution of the number of queens per gall was not statistically different from that expected from a null model based on random allocation. Microsatellite analysis on naturally associated queens showed no evidence of relatedness among them. We then investigated the possible advantages of pleometrotic foundation, comparing the survival and brood production of queens spontaneously nesting alone or in pairs, in small and large nests. Paired queens never showed any form of cooperation in brood care and interacted aggressively or tried to avoid each other. Mortality of paired queens was always greater than that of solitary queens, and mortality was higher in small than large nests. Finally, the larger queen in a pair was more likely to survive the fights. The total number of eggs produced by queens in pairs was nearly twice that produced by isolated queens, although the total progeny production (larvae, pupae, and workers) was the same. This suggests significantly higher brood attrition in paired queens than in solitary ones, probably due to an increase in egg cannibalism or trophic egg production. Further, the time until first worker eclosion was the same for pleometrotic and haplometrotic queens. These results suggest that associative foundation in C. scutellaris is more likely to be the result of a random process, probably triggered by the need to escape from predation and abiotic stresses after the nuptial flight, than an active choice of queens. Additionally, the possible advantages of associative foundation, if any, should be very limited.

description: We apply the Bogoliubov transformations in order to connect two different vacuums, one~located at past infinity and another located at future infinity around a black hole inside the scenario of the nonlinear theory of massive gravity. The presence of the extra degrees of freedom changes the behavior of the logarithmic singularity and, as a consequence, the relation between the two Bogoliubov coefficients. This has an effect on the number of particles, or equivalently, on the black hole temperature perceived by observers defining the time arbitrarily.

Crematogaster abstinens and Crematogaster pygmaea (Hymenoptera: Formicidae: Myrmicinae): from monogyny and monodomy to polygyny and polydomy

description: Polygyny and polydomy are key features in the nesting biology of many ants, raising important questions in social insect biology, in particular about the ecological determinants of such derived traits. One relevant way to investigate those questions is the comparative study of closely related species with contrasting colony structure. In our study, we investigated and compared morphological (morphology of queens, workers and males), chemical (cuticular hydrocarbon profiles), behavioral (attractiveness of queens and substrates chemically marked by queens, colony foundation, mating behavior), and colony-structure (nest architecture, queen number, nest number) traits in Crematogaster abstinens Forel, 1899 and C. pygmaea Forel, 1904, two related Neotropical species. Our aim was to provide evidence of close evolutionary relationship between the two species and to give new insight into the ecological significance of the polygynous and polydomous system found in C. pygmaea. We first showed that the two species share important traits supporting a close evolutionary relationship: same basic morphology in workers and queens, with high queen / worker dimorphism, and ground-dwelling habit with almost identical nest architecture. The two species also share a significant part of their cuticular hydrocarbon (CHC) profiles, which possibly explains the observed attractiveness of substrates marked by queens of one species to workers of the other species. However, the two species completely differ in colony structure: highly polygynous and polydomous colonies in C. pygmaea; small, monogynous and monodomous colonies in C. abstinens. They also show, in addition to the shared compounds, significant differences in their Chc profiles and differ in mating and colony foundation behavior. In previous studies, the probable existence of a dual dispersal strategy in C. pygmaea was shown: a long-range dispersal strategy followed by independent colony foundation and a short-range dispersal strategy through budding events associated with seasonal polygyny and polydomy. We hypothesize that in C. pygmaea, polygyny and polydomy could represent a combined evolutionary response to efficiently explore and rapidly saturate patchily distributed habitats that are unstable and subject to a strong seasonality. We also speculate that the polygynous and polydomous colony structure observed in C. pygmaea is a derived condition from the monogyny and monodomy observed in C. abstinens.

description: Griffis takes pains to point out numerous contributions of early Korean civilization in art and culture throughout Japanese history. Although he criticizes the rise of Japanese militarism, Griffis does not doubt the good will of Japanese colonial policies in Korea. He contextualizes the March 1st movement in the world history, as follows: “From Ireland to Korea, a mighty wave stirs mankind. This movement, instead of being an affair hopelessly archaic, affects our own recent history. It touches even the crux of politics, during this very year of our Lord, 1919; laying bare the taproot of problems that imminently menace the peace of the world. It also shows that race and religion are indestructible, yet ever tending to world unity.”

description: One of the distinctive features of eusocial insects is the production of separate castes, each of which specializes in different aspects of colony performance. As a consequence, queens, males, and workers follow different evolutionary trajectories, depending on their life histories and tasks within the colony. The short-lived males and long-lived queens only leave the colony for reproduction, whereas workers experience frequent contact with the surrounding environment. Yet, workers often perform tasks sequentially during their life. Younger workers tend brood, whereas older workers forage for food. Here, we examined the expression of nine candidate genes both at the constitutive level and following challenge with the entomopathogenic fungus Beauveria bassiana (Vuillemin, 1912) in males, young queens, nurses, and foragers of the ant Formica exsecta Nylander, 1846. We found no difference in the survival following an infection between queens and males or between nurses and foragers. However, we found clear caste- and worker class-specific differences in the response to B. bassiana in genes associated with immune functions. In queens and nurses, the expression of antifungal genes increased, which in the queens was coupled to reduced expression of genes not directly involved in immune responses. In contrast, in males and foragers, gene expression did not increase upon infection; instead the expression of antibacterial genes declined.

description: This paper has two clear motivations: a technical and a practical. The technical motivation unifies in a single and crystal clear formulation a huge family of inequalities that have been produced separately in the last 90 years in different contexts. But we do not just join inequalities; our method also create a family of inequalities invisible by previous approaches. The practical motivation is to show that our deeper approach has strength to attack various problems. We provide new applications of our family of inequalities, continuing the recent work by Maia et al., that, by using our main theorem, substantially improved an inequality of Carando et al. which seemed impossible to be achieved by their original method.

description: Species delimitation is fundamental for many biological studies; its importance extends from regional faunistics over behavioral research to the reconstruction of evolutionary history. However, species delimitation in the Palearctic Tetramorium caespitum species complex (formerly Tetramorium caespitum / impurum complex) has stayed ambiguous over a century. A 2006 study argued for the presence of eight Western Palearctic cryptic species but did not draw formal taxonomic conclusions due to multiple unresolved issues. Using 1428 nest samples in an in-depth integrative-taxonomy approach, we here revise the European species of the complex. Unsupervised analyses provide independent species hypotheses based on molecular and morphological disciplines. Following the unified species concept, we show the presence of ten clearly distinguishable European species differing in mitochondrial Dna, nuclear Dna, morphology of workers and males, and ecology. We explain the evolution of the observed mitochondrial-nuclear discordances by peripatric speciation, historical introgression, and recent hybridization, and that of morphological-nuclear discordances by interspecific similarity and intraspecific variability, that is, morphological crypsis. Based on the final species hypotheses, we confirm T. caespitum (Linnaeus, 1758), T. impurum (Foerster, 1850), T. indocile Santschi, 1927, T. hungaricum RÖSZLER, 1935, and T. alpestre Steiner, SCHLICK-STEINER & Seifert, 2010 as good species. We raise T. fusciclava Consani & Zangheri, 1952 stat.n., T. staerckei KRATOCHVÍL, 1944 sp.rev., and T. immigrans Santschi, 1927 stat.n. (as an introduced species also in the Americas) to species rank and synonymize T. semilaeve var. kutteri Santschi, 1927 under T. indocile and T. staerckei var. gregori KRATOCHVÍL, 1941 under T. impurum. Finally, we newly describe T. breviscapus sp.n. and T. caucasicum sp.n. We present dichotomous determination keys to workers and males and make freely available an online identification key to workers at https://webapp.uibk.ac.at/ecology/tetramorium/. Of relevance to resolving other highly complicated taxonomic problems, we highlight that no single data type was sufficient to disentangle the final species boundaries, which underlines the importance of integrating multiple data sources in taxonomy.

description: Cosmological parameter estimation is entering a new era. Large collaborations need to coordinate high-stakes analyses using multiple methods; furthermore such analyses have grown in complexity due to sophisticated models of cosmology and systematic uncertainties. In this paper we argue that modularity is the key to addressing these challenges: calculations should be broken up into interchangeable modular units with inputs and outputs clearly defined. We present a new framework for cosmological parameter estimation, CosmoSIS, designed to connect together, share, and advance development of inference tools across the community. We describe the modules already available in CosmoSIS, including CAMB, Planck, cosmic shear calculations, and a suite of samplers. We illustrate it using demonstration code that you can run out-of-the-box with the installer available at http://bitbucket.org/joezuntz/cosmosis

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Shape dynamics is classical theory of gravity which agrees with general relativity in many important cases, but possesses different gauge symmetries and constraints. Rather than spacetime diffeomorphism invariance, shape dynamics takes spatial diffeomorphism invariance and spatial Weyl invariance as the fundamental gauge symmetries associated with the gravitational field. Since the area of the event horizon of a black hole transforms under a generic spatial Weyl transformation, there has been some doubt that one can speak sensibly about the thermodynamics of black holes in shape dynamics. The purpose of this paper is to show that by treating the event horizon of a black hole as an interior boundary, one can recover familiar notions of black hole thermodynamics in shape dynamics and define a gauge invariant entropy that agrees with general relativity.

Understanding is provided by state-of-the-art theoretical Random Phase Approximation (RPA) calculatios for deformed nuclei using for the first time a realistic nucleon-nucleon interaction derived from the Argonne V18 potential with the unitary correlation operator method and supplemented by a phenomenological three-nucleon contact interaction. A wavelet analysis allows to extract significant scales both in the data and calculations characterizing the fine structure of the GDR. The fair agreement supports that the fine structure arises from ground-state deformation driven by alpha clustering.

description: Game-Based Student Response Systems (GBSRS) are tools for improving learning through student interaction and participation. Promoting a good user experience in GBSRS is essential in adopting such tools in the educational context. In this sense, it is necessary to design GBSRS by thinking about how to provide the best experience for users. This paper presents an investigation of UX problems in two GBSRS tools, Kahoot! and Quizizz, to verify whether we could avoid UX problems even in the initial stages of product design. For that, we performed a repid review, and from the selected articles, we cataloged and classified general problems in the tools from the perspective of the UX elements defined by Garret's framework. Our results showed that the problems identified in our analysis could be avoided if we applied UX principles in the tool design phase.

An explicit minimax detection boundary is established between the rareness and weakness of the complex sinusoids hidden in the series. The OPHC test is shown to be asymptotically powerful in the detectable region. Numerical simulations illustrate and verify the effectiveness of the proposed test. Furthermore, the periodogram over-sampled by $O(\log N)$ is proven universally optimal in global testing for periodicities under a mild minimum separation condition.

description: We introduce a notion of fine Tannakian infinity-categories and prove Tannakian characterization results for symmetric monoidal stable infinity-categories over a field of characteristic zero. It connects derived quotient stacks with symmetric monoidal stable infinity-categories which satisfy a certain simple axiom. We also discuss several applications to examples.

description: We are interested in the 3-Calabi-Yau categories $\mathcal{D}$ arising from quivers with potential associated to a triangulated marked surface $\mathbf{S}$ (without punctures). We prove that the spherical twist group ST of $\mathcal{D}$ is isomorphic to a subgroup (generated by braid twists) of the mapping class group of the decorated marked surface $\mathbf{S}_{\bigtriangleup}$. Here $\mathbf{S}_{\bigtriangleup}$ is the surface obtained from $\mathbf{S}$ by decorating with a set of decorated points, where the number of points equals the number of triangles in any triangulations of $\mathbf{S}$. For instance, when $\mathbf{S}$ is an annulus, the result implies the corresponding spaces of stability conditions on $\mathcal{D}$ is contractible.

description: This study investigated the impact of occupational stress on job performance of selected secondary school teachers in Ondo West Local Government Area of Ondo State. Descriptive survey research design was adopted for the study. The population of the study comprised randomly selected secondary school teachers from the following listed schools in Ondo West Local Government Area of Ondo State. A sample of One Hundred and Twenty (120) secondary school teachers in Ondo West Local Government Area of Ondo State was randomly selected for the purpose of the study. The instrument used for data collection for this study is a self-made questionnaire designed by the researcher. Data gathered were analysed using frequency counts and percentage of response to the items in the research instrument was calculated to answer the research questions. The study revealed that public school teachers experience less occupational stress, private school teachers experience more occupational stress, occupational stress has more impact on private school teachers and private school teachers easily recover from occupational stress. The study discovered that occupational stress on secondary school teachers may lead to frequent illnesses, encourage perpetual absenteeism in the school, makes teachers develop chronic disease, and may also result to depression. The study recommended that for teachers to discharge their duties effectively and efficiently there is need for government and managers of private secondary schools to improve teachers' condition of service. Government and owners of private schools should provide adequate school facilities in schools to enable teachers discharge their duties without stress in a conducive environment and well equipped classroom that will aid effective teaching and learning.

description: We give two variational formulas (qVar1) and (qVar2) for the quenched free energy of a random walk in random potential (RWRP) when (i) the underlying walk is directed or undirected, (ii) the environment is stationary and ergodic, and (iii) the potential is allowed to depend on the next step of the walk which covers random walk in random environment (RWRE). In the directed i.i.d. case, we also give two variational formulas (aVar1) and (aVar2) for the annealed free energy of RWRP. These four formulas are the same except that they involve infima over different sets, and the first two are modified versions of a previously known variational formula (qVar0) for which we provide a short alternative proof. Then, we show that (qVar0) always has a minimizer, (aVar2) never has any minimizers unless the RWRP is an RWRE, and (aVar1) has a minimizer if and only if the RWRP is in the weak disorder regime. In the latter case, the minimizer of (aVar1) is unique and it is also the unique minimizer of (qVar1), but (qVar2) has no minimizers except for RWRE. In the case of strong disorder, we give a sufficient condition for the nonexistence of minimizers of (qVar1) and (qVar2) which is satisfied for the log-gamma directed polymer with a sufficiently small parameter. We end with a conjecture which implies that (qVar1) and (qVar2) have no minimizers under very strong disorder.

description: In this paper, we explain how generalized dynamical r-matrices can be obtained by (quasi-)Poisson reduction. New examples of Poisson structures and Poisson groupoid actions naturally appear in this setting. As an application, we use a generalized dynamical r-matrix induced by the gauge fixing procedure to give a new finite dimensional description of the Atiyah-Bott symplectic structure on the moduli space of flat connections on a surface.

description: In $\mathcal{N}=1$ superconformal theories in four dimensions the two-point function of superconformal multiplets is known up to an overall constant. A superconformal multiplet contains several conformal primary operators, whose two-point function coefficients can be determined in terms of the multiplet's quantum numbers. In this paper we work out these coefficients in full generality, i.e. for superconformal multiplets that belong to any irreducible representation of the Lorentz group with arbitrary scaling dimension and R-charge. From our results we recover the known unitarity bounds, and also find all shortening conditions, even for non-unitary theories. For the purposes of our computations we have developed a Mathematica package for the efficient handling of expansions in Grassmann variables.

description: We construct a sequence of Markov processes on the set of dominant weights of an affine Lie algebra $\mathfrak{g}$ considering tensor product of irreducible highest weight modules of $\mathfrak{g}$ and specializations of the characters involving the Weyl vector $ρ$. We show that it converges towards a space-time Brownian motion with a drift, conditioned to remain in a Weyl chamber associated to the root system of $\mathfrak{g}$.

description: This deliverable presents the first release of the functional and non-function specifications of the iHELP solution, that will guide the development activities throughout the project, in order to achieve a consensus on what the iHelp platform will offer. This has a two-fold advantage as it will let the developers know what to build and the users what they will get.
 These specifications explain how the requirements provided by the pilots and the technical partners will be fulfilled by the iHelp platform and provide a detailed definition of the functionalities/behaviours of the iHelp components and the interactions among them. Details on the design of the components are outlined in the related deliverables and are out of the scope of this document.
 This work started from the outcomes of the requirements elicitation and architectural design, specifically the requirements in D2.1 – State of the art and requirements analysis I (M., M., P. + 21) and the architecture in D2.4 – Conceptual model and reference architecture I (Mel 21). Use cases reported in D2.1 have been analyzed to identify the iHelp components functions needed to satisfy them. The architecture has been examined to understand the role and objective of each component, and the technical specification has been produced for the most mature components at the current stage of the project, while the overall platform will be designed incrementally in accordance to the progresses of the project, and documented in the final version of the present report. Technical partners responsible for the components have been provided with a template and guidelines facilitating the production of the technical specifications and API documentation. Connection mechanisms, data flows and control flows have been discussed and clarified during frequent brainstorming involving all interested parties. Requirements specified in D2.1 (M., M., P. + 21) have been reviewed to derive the non-functional specifications.
 The next version of this deliverable D2.7 – Functional and Non-Functional Specifications II, expected at M20, will report the functional and non-functional specifications of the whole iHelp platform and components.
