description: Leben und Werk Werner Lindners waren in vielerlei Hinsicht durch seine bürgerliche Herkunft, das industriell bestimmte Umfeld seiner Jugend, die Ansichten und Wertvorstellungen seiner Zeitgenossen sowie die bewegten wirtschaftlichen, sozialen und politischen Bedingungen seiner Zeit geprägt. Dies spiegeln die einzelnen Phasen seiner Berufstätigkeit während des Ersten Weltkriegs, der Weimarer Republik und der NS-Zeit als Fachbeauftragter des "Deutschen Heimatbundes" wider. Die Vielschichtigkeit seines Oeuvres als Mitgestalter der Industriemoderne einerseits und Vertreter des Heimatschutzes und "Bewahrer" regionaler Identität andererseits, ist ein Charakteristikum von Person und Werk. In der Verbindung der noch heute so gegensätzlich erscheinenden Pole von Industriemoderne und Heimatschutz erscheint Lindner idealtypisch für die Bewegung der ersten Hälfte des 20. Jahrhunderts. Das Werk Werner Lindners verdeutlicht, dass die eigenständigen kulturellen Werte des Industriebaus auch von den Vertretern des Traditionalismus anerkannt und als Vorbild für die Reform der zeitgenössischen Baukunst gesehen wurden. Sehr früh hat er sich mit der Gestaltung der vielfältigen Erscheinungsformen der Industriemoderne auseinandergesetzt. Ausgehend von Telegrafenmasten und Transformatorenhäuschen auf dem Lande bis hin zu hochtechnisierten Industrieanlagen standen die gestalterischen Anforderungen aus dem plötzlichen Anwachsen der Industrie, die gestalterische Qualität industrieller Gebäude und Produkte und daher der industriell-kulturellen Entwicklung im Mittelpunkt seines Interesses.

description: Organometallic clusters based on transition metal atoms are interesting because possible applications in spintronics and quantum information. In addition to the enhanced magnetism at the nanoscale, the organic ligands may provide a natural shield again unwanted magnetic interactions with the matrices required for applications. Here we show that the organic ligands may lead to non-collinear magnetic order as well as the expected quenching of the magnetic moments. We use different density functional theory (DFT) methods to study the experimentally relevant three cobalt atoms surrounded by benzene rings (Co$_3$Bz$_3$). We found that the benzene rings induce a ground state with non-collinear magnetization, with the magnetic moments localized on the cobalt centers and lying on the plane formed by the three cobalt atoms. We further analyze the magnetism of such a cluster using an anisotropic Heisenberg model where the involved parameters are obtained by a comparison with the DFT results. These results may also explain the recent observation of null magnetic moment of Co$_3$Bz$_3^+$. Moreover, we propose an additional experimental verification based on electron paramagnetic resonance.

The Impact of Exchange Volatility on the Agricultural Exports of Sub Saharan African Countries
Creators: name: Tekle, Biruk
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: The abandonment of the fixed exchange rate systems has caused exchange rate movements to become a major concern for traders, policy makers and researchers. Numerous studies have been conducted to determine whether exchange rate volatility affected international trade flows. Nevertheless, no general consensus has been reached as to the magnitude and direction of the impact of exchange rate volatility on trade flows. This paper investigates the impact of exchange rate volatilities on the agricultural exports of Sub Saharan African countries. Twenty nine sample SSAcountries were selected for the period 1996-2008. Estimation is made using random effects model, difference generalized methods of moments (GMM) and systems GMM. Volatilities of the official exchange rate of SSA countries was generated using GARCH (1,1) and ARCH models. The Standard gravity model augmentedby variables which affect the trade between the SSA countries and the major trading countries is estimated. Exchange rate volatilities is found to have a negative and significant impact on the agricultural exports of the SSA countries across the different estimation techniques. Trade policies that are designed to increase exports might create uncertainty in the exchange rate and ultimately end up reducing exports. The main lesson drawn from the study is, SSA countries should have a stable exchange rate policy Key words: Exchange rate volatilities, gravity model, system GMM, GARCH , ARCH

description: In Ik, a Kuliak language of Uganda, non-contiguous metathesis occurs, in which the consonants of CVC(V), CVCVC, and longer roots, swap places. When this happens synchronically, the original un-metathesized form and the metathesized form differ only in terms of metathesis and remain synonymous. However, the language also contains a significant number of sets of semantically similar words characterized by the same type of metathesis plus other sound changes, which – even when (near-) synonymous – are fully lexicalized. On this basis, this talk makes the case that non-contiguous metathesis must have been a productive diachronic process in forming the Ik lexicon – from within Ik and/or through borrowing. And since some of these metathetic sets extend beyond Ik/Kuliak into other regional languages, a second claim of the talk is that metathesis must have been operative diachronically in languages of other phyla with which Ik/Kuliak has had contact. This would mean that, owing to its radical restructuring of words, metathesis has left highly salient and traceable clues to the historical interactions and influences among East African languages. After a brief survey of the typology of metathesis (including possible motivations), examples of Ik non-lexicalized and lexicalized metathesis will be presented, followed by several metathetic cognate sets that cross language family boundaries.

description: We study dynamic network flows with uncertain input data under a robust optimization perspective. In the dynamic maximum flow problem, the goal is to maximize the flow reaching the sink within a given time horizon $T$, while flow requires a certain travel time to traverse an edge. In our setting, we account for uncertain travel times of flow. We investigate maximum flows over time under the assumption that at most $Γ$ travel times may be prolonged simultaneously due to delay. We develop and study a mathematical model for this problem. As the dynamic robust flow problem generalizes the static version, it is NP-hard to compute an optimal flow. However, our dynamic version is considerably more complex than the static version. We show that it is NP-hard to verify feasibility of a given candidate solution. Furthermore, we investigate temporally repeated flows and show that in contrast to the non-robust case (that is, without uncertainties) they no longer provide optimal solutions for the robust problem, but rather yield a worst case optimality gap of at least $T$. We finally show that the optimality gap is at most $O(ηk \log T)$, where $η$ and $k$ are newly introduced instance characteristics and provide a matching lower bound instance with optimality gap $Ω(\log T)$ and $η= k = 1$. The results obtained in this paper yield a first step towards understanding robust dynamic flow problems with uncertain travel times.

description: A Data Use Agreement (DUA) is a contract that governs the exchange of specific data between parties. Data Use Agreements establish who is permitted to use and receive a unique dataset, and how that user may use and disclose the data. Often, Data Use Agreements serve as a guaranteed first point of contact between data stewards and researchers in the community. As universities continue to grapple with issues of data security and intellectual property, Data Use Agreements are becoming tools to ensure an ethical foundation for research. 

At our university libraries, creating and implementing Data Use Agreements is a component of the data acquisitions workflow. During this presentation, we will discuss our university libraries’ approach to creating and implementing Data Use Agreements and provide a general framework for actualizing Data Use Agreements at attendees’ home institutions. We will share how to identify key criteria for knowing when to employ these Agreements, as well as who across a broad community of internal stakeholders (such as subject specialists, acquisitions staff, licensing librarians and data support specialists) should participate in their development. We will also review practical and scalable tools, such as templates, for drafting Data Use Agreements, and how to leverage programs like Qualtrics and Redivis to manage user assent. Finally, we will acknowledge and share current workflow challenges and our approaches to solving them.

subject: FOS: Economics and business

description: Trading algorithms that execute large orders are susceptible to exploitation by order anticipation strategies. This paper studies the influence of order anticipation strategies in a multi-investor model of optimal execution under transient price impact. Existence and uniqueness of a Nash equilibrium is established under the assumption that trading incurs quadratic transaction costs. A closed-form representation of the Nash equilibrium is derived for exponential decay kernels. With this representation, it is shown that while order anticipation strategies raise the execution costs of a large order significantly, they typically do not cause price overshooting in the sense of Brunnermeier and Pedersen.

description: This talk focuses on singulative markers used in the expression of number in Cushitic languages (Afro-Asiatic) spoken in Sudan, Eritrea, Ethiopia, Djibouti, Somalia, Kenya and Tanzania. The term singulative indicates a morphologically derived number form denoting at least “one individual” or “a/one unit”. A singulative is formed by adding a marker to a non-unit denoting base, as shown in Saho (1). (1) Saho (Zaborski 1986:23) baqhla (f) ‘mule(s)’ base baqhla-t-to (m), baqhla-t-tó (f) ‘a/one mule’ singulative baaqhil ‘mules’ (m) plurative The current stage of my project is devoted to the distribution of an online questionnaire designed to elicit nouns having the following number values: base (non-number-specific), singulative, plurative or, possibly, paucative. See (2) for a complete paradigm in Saho. (2) Saho (Zaborski 1986:21) adám ‘man’ base adám-to (m), adám-tó (f) ‘a/one man’ singulative adám-um ‘men’ plurative adám-tit ‘a few men’ paucative The data collected via questionnaire, will be the base for a semantic analysis on singulative nouns in a sample of Cushitic languages. The languages included in the questionnaire are: ˁAfar (Qafar), Alaaba-K’abeena (Alaba, Halaba, Qebena, Wanbasana), Alagwa, Arbore, Aweer (“Boni”), Bayso (Baiso), Beja, Bilin (Bilen), Burji (Burǧi, Bembala, Daashi), Burunge, Dahalo, Dhaasanach (Dasenech, Daasanach, Dhaasanac, Marille, Gallab, Geleba, Dama), Diraytata (Dirayta, Dirasha, Gidole), Gawwada (Dullay, Gollango, Ale-Gawwada), Gedeˀo (Gedeo, Derasa, Darasa), Gorwaa (Gorowa), Hadiyya (Hadiyyisa), Iraqw, Kambaata, K’emant (Qimant, Kemant), Konso, Oromo Borana (Boraana, Borana-Arsi-Guji), Oromo Harar (Eastern Oromo), Oromo Orma, Oromo Rayya (Raya), Oromo Waata, Oromo Wellegga (Welega), Saho (Saaho), Sidaama (Sidamo, Sidaamu, Sidamu), Ts’amakko (Tsamai, S’amai, Tamaha, Bago), Xamtanga (Khamtanga, Khamir, Khamta, Agawinya).

description: In this paper, we propose $\mathrm{CeCoIn_5}/\mathrm{YbCoIn_5}$ superlattice systems as a test bed for the reduction of topological classification in free fermions. We find that the system with quad-layer of $\mathrm{CeCoIn_5}$ shows a topological crystalline superconducting phase with the mirror Chern number eight at the non-interacting level. Furthermore, we demonstrate that in the presence of two-body interactions, gapless edge modes are no longer protected by the symmetry in the system with quad-layer, but are protected in the systems with bi- or tri-layer. This clearly exemplifies the reduction of topological classification from $\mathbb{Z}\oplus\mathbb{Z}$ to $\mathbb{Z}\oplus\mathbb{Z}_8$.

description: We explore the detection, with upcoming spectroscopic surveys, of three-dimensional power spectra of emission line fluctuations produced in different phases of the Interstellar Medium (ISM) by ionized carbon, ionized nitrogen and neutral oxygen at redshift z>4. The emission line [CII] from ionized carbon at 157.7 micron, and multiple emission lines from carbon monoxide, are the main targets of planned ground-based surveys, and an important foreground for future space-based surveys like the Primordial Inflation Explorer (PIXIE). However, the oxygen [OI] (145.5 micron) line, and the nitrogen [NII] (121.9 micron and 205.2 micron) lines, might be detected in correlation with [CII] with reasonable signal-to-noise ratio (SNR). These lines are important coolants of both the neutral and the ionized medium, and probe multiple phases of the ISM. We compute predictions of the three-dimensional power spectra for two surveys designed to target the [CII] line, showing that they have the required sensitivity to detect cross-power spectra with the [OI] line, and the [NII] lines with sufficient SNR. The importance of cross-correlating multiple lines is twofold. On the one hand, we will have multiple probes of the different phases of the ISM, which is key to understand the interplay between energetic sources, the gas and dust at high redshift. This kind of studies will be useful for a next-generation space observatory such as the NASA Far-IR Surveyor. On the other end, emission lines from external galaxies are an important foreground when measuring spectral distortions of the Cosmic Microwave Background spectrum with future space-based experiments like PIXIE; measuring fluctuations in the intensity mapping regime will help constraining the mean amplitude of these lines, and will allow us to better handle this important foreground.

description: Se realizó una investigación exhaustiva de distintas fuentes bibliográficas sobre un Sistema de Gestión de Seguridad de la Información (SGSI). Para la ejecución de estos, existen distintas normativas y metodologías que facilitan su implementación y mantenimiento del mismo. La carencia de los SGSI se da principalmente en la pequeñas y medianas empresas (PYMES) en virtud de diversas razones, entre las más importantes están los altos costos que conlleva la implementación y mantenimiento de un SGSI y a la gran complejidad que los caracteriza. Por tal motivo se investigó una metodología, MARISMA-AGR, que se pueda implementar en las PYMES, pero también se puede efectuar en grandes empresas, teniendo en cuenta los dos problemas que inhiben el uso de este tipo de herramientas: costos y complejidad. Luego se procedió a explicar los elementos más importantes de la metodología, y se realizó un análisis crítico donde se expusieron sus principales debilidades (no tiene software de apoyo, metodología con poca madurez, muy nueva para el año en que se realizó la consulta (2020)). Existe la referencia de que hoy día, el 81% de los funcionarios de empresas grandes y pequeñas tienen acceso a internet y sin embargo, según un reciente estudio, el presupuesto perfilado para la seguridad digital que permite amortiguar los ataques informáticos y aumentar la protección de sus activos es del menos del 1% de las ventas o inversiones. (Rosario, 2019) Metodologías como Octave, Magerit o Mehari, suelen ser complejas y costosas, en especial para las PYMES, se procedió a la realización de otra investigación para hallar metodologías para un SGSI que no solo se enfoquen en este tipo de empresas, sino que con el tiempo se extiendan a cualquier entidad o institución, más allá de su tamaño. Por último, se propuso la creación de un SGSI basado en la metodología MARISMA que ayude a realizar el análisis de riesgo.

Our results apply to a number of examples: sums of stationary correlated random variables whose scaling limit is fractional Brownian motion, random walks in random sceneries, random processes in Brownian scenery, and the Matheron-de Marsily model in Z^2 with random orientations of the horizontal layers. Using a new approach, strongly related to the study of the range, we obtain an upper bound of optimal order in the general case and improved lower bounds (compared to previous literature) for many processes.

description: This paper attempts to study the determinant of FDI in Ethiopia for the time period from 1980-2015. To this end, the study has reviewed theoretical explanations relating to the determinants of foreign direct investment and the study has also reviewed relevant empirical literatures focusing on the determinants of FDI in the context of developing countries. Using Data on foreign direct investment and number of telephone users that is obtained from United Nations Conference on Trade and Development (UNCTAD). Real effective exchange rate, inflation rate, export and import data were obtained from National Bank of Ethiopia (NBE), and Ethiopia Real GDP from Ministry of Finance and Economic Development (MoFED). By adopting model that was used by Erdal Demirhan etal (2008) this paper examine prominent determinants of FDI and finds that economic growth, macroeconomic stability, openness to trade are important determinants of foreign direct investment. The results suggest policy makers should give due attention to promoting liberalization and implementing sound economic policies that can ensure macroeconomic stability in the country.

description: The COVID-19 pandemic has been an unprecedented worldwide phenomenon that has impacted virtually every aspect of life with certain populations experiencing the brunt more than others. Many immigrant Latine English as a second language (ESL) adult learners have had to grapple with a variety of historical and novel challenges regarding stress, health, immigration, employment, and education. This mixed-methods research study aimed to better understand the effects of the COVID-19 pandemic on a group of immigrant Latine ESL adult learners in Philadelphia and the forms of capital they possess that help them obtain resources, navigate through challenging events, and mitigate damages. Thirty-six participants (18 to 50+ years; 63.89% female) participated in a survey that addressed stress level, learning of English, employment, health, and community cultural wealth. Quantitative analyses revealed that the pandemic had a negative impact on employment and the contraction of COVID-19 and that the sample possessed all forms of capital under investigation. Qualitative analyses revealed that the pandemic had a negative impact on family, finances/unemployment, health, learning of English, friends, immigration, isolation, and uncertainty about the future.

description: Of the 7 000 languages on our planet, some are described in great detail in extensive grammatical descriptions (such as Kiswahili or English), some in a smaller number of shorter publications (e.g., Betoi --- an extinct language of Venezuela), and yet others hardly at all (e.g., Mor --- a minority language of Papua, Indonesia). At the same time, the languages of the world are endangered to various degrees (see, e.g., Moseley 2010). In order to best prioritize language documentation, knowledge of the extant documentation for every single language is obviously crucial (Hauk & Heaton 2018). Perhaps surprisingly, until now there has never been a full survey, but thanks to Glottolog (glottolog.org) there is now a sufficiently comprehensive bibliography for lesser-known languages. We will present the empirical results on language description so far worldwide, in Africa and the Rift Valley especially. Finally, we will look at some concrete suggestions for languages in need of description prioritizable from the perspectives of diversity and endangerment.

description: Frauchiger and Renner have recently claimed to prove that "Single-world interpretations of quantum theory cannot be self-consistent". This is contradicted by a construction due to Bell, inspired by Bohmian mechanics, which shows that any quantum system can be modelled in such a way that there is only one "world" at any time, but the predictions of quantum theory are reproduced. This Bell-Bohmian theory is applied to the experiment proposed by Frauchiger and Renner, and their argument is critically examined. It is concluded that it is their version of "standard quantum theory", incorporating state vector collapse upon measurement, that is not self-consistent.

description: In this manuscript, it is shown that the group of $K_1$-zero-cycles on the second generalized Severi-Brauer variety of an algebra $A$ of index 4 is given by elements of the group $K_1(A)$ together with a square-root of their reduced norm. Utilizing results of Krashen concerning exceptional isomorphisms, we translate our problem to the computation of cycles on involution varieties. Work of Chernousov and Merkurjev then gives a means of describing such cycles in terms of Clifford and spin groups and corresponding $R$-equivalence classes. We complete our computation by giving an explicit description of these algebraic groups.

description: Shetler will talk about her work over the last ten years to make digitally accessible the oral tradition interviews from 1995 on, including audio, video, photographs, transcripts and other related materials, to scholars and to people in the Mara Region Tanzania. This was accomplished by a three year National Endowment for the Humanities grant that finished its first year with the digital library website going live in June maraculturalheritage.org. In July Shetler visited Tanzania and was able to talk to people at the University in DSM, the Ministry of Education in Mara and lots of collaborators in the Mara Region who were introduced to the digital library on a cell phone. Project assistants will continue to add to the digital library over the next two years, including adding a collection of materials from a local popular historian dating back to interviews in 1977. The collection holds interviews in many Bantu languages from the Mara Region as well as Luo and Dadog, adding significant value for language preservation. Documents include locally produced dictionaries, core vocabulary lists, music and dance performances, family and community histories and statistical data. Shetler will talk about the joys and challenges going forward in managing this project.

description: Multiparametric families of hypergeometric $τ$-functions of KP or Toda type serve as generating functions for weighted Hurwitz numbers, providing weighted enumerations of branched covers of the Riemann sphere. A graphical interpretation of the weighting is given in terms of constellations mapped onto the covering surface. The theory is placed within the framework of topological recursion, with the Baker function at ${\bf t} ={\bf 0}$ shown to satisfy the quantum spectral curve equation, whose classical limit is rational. A basis for the space of formal power series in the spectral variable is generated that is adapted to the Grassmannian element associated to the $τ$-function. Multicurrent correlators are defined in terms of the $τ$-function and shown to provide an alternative generating function for weighted Hurwitz numbers. Fermionic VEV representations are provided for the adapted bases, pair correlators and multicurrent correlators. Choosing the weight generating function as a polynomial, and restricting the number of nonzero "second" KP flow parameters in the Toda $τ$-function to be finite implies a finite rank covariant derivative equation with rational coefficients satisfied by a finite "window" of adapted basis elements. The pair correlator is shown to provide a Christoffel-Darboux type finite rank integrable kernel, and the WKB series coefficients of the associated adjoint system are computed recursively, leading to topological recursion relations for the generators of the weighted Hurwitz numbers.

description: Iron is one of the most abundant elements inside the deep Earth. Numerous geologically relevant iron bearing materials are well characterized utilizing minerals obtained e.g. from volcano eruptions. Here, typical geophysical and geochemical properties of iron, especially the oxidation state, local coordination and spin state, are subject of extensive research in order to understand the structural and electronic properties of minerals as well as the mechanism of chemical reactions at extreme conditions. The local chemical and physical properties of iron in minerals can be studied by core-level spectroscopy using sensitive techniques like x-ray absorption or electron energy loss spectroscopy, which are routinely applied to measure absorption edges of elements in compounds. However, these tools cannot be applied at extreme conditions when diamond anvil cells in combinations with external or laser heating are utilized. X-ray Raman scattering, a non-resonant inelastic X-ray scattering technique, can be used for bulk sensitive studies of low energy absorption edges by hard x-rays. In contrast to x-ray absorption spectroscopy or electron energy loss spectroscopy, X-ray Raman scattering can be applied also using highly absorbing sample environments being a perfect alternative for high pressure high temperature applications. On the way towards extreme conditions, novel measurements of the Fe L2/3- and M2/3-are performed on pre-characterized geologically relevant materials to prove the capability of such a study as well the sensitivity of the Fe M2/3-edge on the oxidation state and the local coordination of iron in compounds. In addition, the momentum transfer dependence of the spectra, which is a special feature of inelastic X-ray scattering, is discussed. The results are subsequently used to obtain quantitative results about the oxidation state of iron in glasses and to study the impact of the local coordination. Furthermore, first in-situ study of the Fe M2/3-edge is presented to track the high-spin to low-spin transition in FeS at pressures up to 10 GPa. In combination with atomic multiplet crystal field calculations, in-situ measurements of the Fe M2/3-edge can be used to extract quantitative information about the crystal field splitting, the main component of the spin cross-over process. To simulate the conditions of the inner Earth a portable double-sided laser heating setup optimized for inelastic X-ray scattering is designed and constructed in order to provide a possibility to perform high temperature experiments.

description: We provide a brief but self-contained review of two-dimensional conformal field theory, from the basic principles to some of the simplest models. From the representations of the Virasoro algebra on the one hand, and the state-field correspondence on the other hand, we deduce Ward identities and Belavin--Polyakov--Zamolodchikov equations for correlation functions. We then explain the principles of the conformal bootstrap method, and introduce conformal blocks. This allows us to define and solve minimal models and Liouville theory. In particular, we study their three- and four-point functions, and discuss their existence and uniqueness. In appendices, we introduce the free boson theory (with an arbitrary central charge), and the modular bootstrap in minimal models.
