description: In this paper we investigate the problem of testing semi parametric hypotheses in locally stationary processes. The proposed method is based on an empirical version of the L2-distance between the true time varying spectral density and its best approximation under the null hypothesis. As this approach only requires estimation of integrals of the time varying spectral density and its square, we do not have to choose a smoothing bandwidth for the local estimation of the spectral density - in contrast to most other procedures discussed in the literature. Asymptotic normality of the test statistic is derived both under the null hypothesis and the alternative. We also propose a bootstrap procedure to obtain critical values in the case of small sample sizes. Additionally, we investigate the finite sample properties of the new method and compare it with the currently available procedures by means of a simulation study. Finally, we illustrate the performance of the new test in a data example investigating log returns of the S&P 500.

description: Marasmius nigripes var. albus Corner, Beih. Nova Hedwigia 111: 75. 1996. Fig. 11e–g
 Holotype:— SINGAPORE. Singapore Botanic Gardens, 15 June 1929, leg. EJH Corner (E #192522!).
 The holotype collection consists of 3 basidiomes in fair condition, two attached to undetermined dicotyledonous leaves, one loose in packet, all 3 parasitized by a white mold. Description of dried holotype: Pileus pallid. Stipe slightly eccentric to central, non-insititious. Basidiospores (7–) 8–10.2 × 7.8–9 μm, tetrahedral, hyaline, inamyloid. Basidia 4-sterigmate. Basidioles clavate. Pleurocystidia absent. Lamellar edges sterile. Cheilocystidia 24–32 × 6.5–9 μm, irregularly cylindrical, sometimes lobate, apex often with a smooth capitulum or diverticulate, densely and coarsely diverticulate elsewhere, hyaline, thin-walled. Pileipellis a well-developed Rameales -structure of coarsely diverticulate hyphae 3–6 (–9) μm diam., non-gelatinized, non-incrusted, hyaline; diverticula knobby, obtuse, irregular in outline; terminal cells coarsely diverticulate or often with a smooth, bulbous capitulum, similar to the cheilocystidia. Pileus trama of weakly gelatinized, smooth hyphae 2.5–6 (–10) μm diam., hyaline, inamyloid. Stipe tissues not observed; material too scanty. Clamp connections present.
 Status: This may be the oldest name for the pure white Tetrapyrgos with short, eccentric stipe and intervenose lamellae from SouthEast Asia and vicinity. Petch (1948: 27) reports a white form of M. subcinereus that represents this species but did not formally describe it as new. We accept Marasmius nigripes var. albus as a synonym of T. subcinerea.

description: In der modernen mathematikdidaktischen Literatur sind "reine" stoffdidaktische Beiträge immer seltener zu finden. Die Zeitschrift "Didaktik der Mathematik", in der vor allem stoffdidaktische Artikel veröffentlicht wurden, gibt es beispielsweise schon lange nicht mehr. Bereits 1985 wurde bei der Lektüre von "Mensch und Mathematik" klar, dass "didaktisches Denkenund Handeln" immer auch die Reflexion des Verhältnisses zur Mathematik mit einschließt. Zehn Jahre später fragte dann Hans-Christian Reichel auf der 29. Tagung für Didaktik der Mathematik in Kassel: "Hat die Stoffdidaktik Zukunft?" Fast zwanzig Jahre danach sollen aktuelle Indikationen – Vernetzungen (im Mathematikunterricht), die Schnittstellenproblematik und der Kompetenzaufbau beim Begründen im Mathematikunterricht – für stoffdidaktische Überlegungen aufgezeigt werden. Dabei sind "didaktisch orientierte Sachanalysen" (Heinz Griesel) gefragt, um eine Beschreibung und Bewertung der Unterrichtstauglichkeit a priori zu ermöglichen. Erich C. Wittmann erweitert den Ansatz der traditionellen Stoffdidaktik zur "strukturgenetischen didaktischen Analyse", die ausdrücklich auch Prozesse mit einbezieht (Wittmann 2014). Das Konzept der "mathematischen Miniatur" bildet mathematisches Tun möglichst unverzerrt ab ("vereinfachen, ohne zu verfälschen") und ist ein Grundsatz für die Darstellung der folgenden Themen aus Stochastik, Analysis und Geometrie.
An Empirical Investigation of capital inflow And Dutch Disease: Evidence from Ethiopia

description: This study investigates the Dutch disease impact of capital inflow using a quarterly time series data from 2000/01 1st quarter to 2016/17 fourth quarter. The study employed three separate re-gressions to examine the impact of capital inflow on spending, resource movement and established the impact of real effective exchange rate shock on net export. Regression analysis was carried out using auto regressive distributed lag (ARDL) approach to examine the impact of Capital inflow on real effective exchange rate and traded to non-traded sector ratio and then applied Bayesian Vector Auto-regressive to find the impact of real effective exchange rate changes on net exports of Ethiopia. The findings reveal that, foreign direct investment and foreign aid inflow does not have Dutch disease impact through spending effect both in the short run and the long run model. In resource movement effect, foreign direct investment inflow does not have any impact on resource reallocation from the tradable agricultural and manufacturing sector to non-tradable service sec-tor. But in the long run, foreign aid exerts a pressure on the movement of labor from the tradable to non-tradable sector ratio. The changes in real effective exchange rate have negative impact on net export in Ethiopia. While, real effective exchange rate respond positively to a unit shock in foreign direct investment and remittance inflow. Again, its response is also insignificant following a unit shock in foreign aid. Hence, there is lack of empirical support of Dutch disease in Ethiopia, suggests that Ethiopia has been able to effectively manage a surge capital inflows.

description: Motivated by the fact that Bardeen black holes do not satisfy the usual first law and Smarr formula, we derive a generalized first law from the Lagrangian of nonlinear gauge field coupled to gravity. In our treatment, the Lagrangian is a function of the electromagnetic invariant as well as some additional parameters. Consequently, we obtain new terms in the first law. With our formula, we find the correct forms of the first law for Bardeen black holes and Born-Infeld black holes. By scaling arguments, we also derive a general Smarr formula from the first law. Our results apply to a wide class of black holes with nonlinear gauge fields.

description: We report on the electronic transport properties of black phosphorus and analyze them using a two-carrier model in a wide range of pressure up to 2.5 GPa. In semiconducting state at 0.29 GPa, the remarkable non-linear behavior in the Hall resistance is reasonably reproduced by assuming the coexistence of two kinds of hole with different densities and mobilities. On the other hand, two-carrier analyses of the magnetotransport properties above 1.01 GPa suggest the coexistence of high mobility electron and hole carriers that have almost the same densities, i.e., nearly compensated semimetallic nature of black phosphorus. In the semimetallic state, analyses of both the two-carrier model and quantum oscillations indicate a systematic increase in the carrier densities as pressure increases. An observed sign inversion of Hall resistivity at low magnetic fields suggests the existence of high mobility electrons (\sim105 cm2 V-1 s-1) that is roughly ten times larger than that of holes, in the semimetallic black phosphorus. We conclude that the extremely large positive magnetoresistance that has been observed in semimetallic state cannot be reproduced by a conventional two-carrier model.

description: Die Deutsche Bibliothek hat einen gesetzlichen Auftrag zur vollständigen Sammlung, Erschließung und dauerhaften Sicherung deutschsprachiger und in Deutschland erschienener Publikationen. Das Gesetz bezieht auch digitale Publikationen ein, sofern sie auf physischen Datenträgern verbreitet werden. Für die Pflichtablieferung von Online-(Netz)Publikationen ist dagegen eine Novellierung des Gesetzes erforderlich. Die Deutsche Bibliothek hat mit Verlagen und sonstigen Produzenten die freiwillige Ablieferung von Belegexemplaren vereinbart, um ausreichend gesicherte Erkenntnisse über Netzpublikationen vor einer gesetzlichen Regelung zu gewinnen. Sie will zügig die Erwerbung, Erschließung, Archivierung und Nutzung von Netzpublikationen in Angriff nehmen, da deren Anzahl ständig steigt und anstehende Fragen geklärt werden müssen. Seit 1. Juli 1998 werden in einem ersten Schritt elektronische Dissertationen und Habilitationen gesammelt. Der Kontakt zwischen der Universität und Der Deutschen Bibliothek erfolgt dabei über die Universitätsbibliothek. Diese meldet das Vorliegen der Netzdissertation per email über ein HTML-Formular oder (demnächst) über einen Dublin Core-Datensatz an. Die Deutsche Bibliothek übernimmt das Dokument dann selbst vom jeweiligen Universitätsserver (pull) und legt es auf ihrem eigenen Dokumentserver deposit.ddb.de ab. Die Dokumentbearbeitung folgt einem elektronischen Laufzettel: Formalerschließung auf der Grundlage von RAK-NBM, Sacherschließung nach den RSWK, Anzeige der Netzdissertation in der Reihe H der Deutschen Nationalbibliographie. Die bibliographischen Angaben werden über die Zentralen bibliographischen Dienstleistungen vertrieben. Der Zugriff auf die elektronischen Dokumente ist sowohl über den OPAC als auch über das Z39.50-Gateway möglich. Ein Zugriff direkt über den Dokumentserver deposit ist geplant. Im zweiten Schritt wurden im August 1998 die Gespräche mit einer ausgewählten Gruppe von Verlagen über die Verfahrensweise bei der Ablieferung elektronischer Verlagspublikationen begonnen. Hierbei geht es zunächst darum, das Spektrum der sammelpflichtigen Veröffentlichungen zu definieren und von den nichtsammelpflichtigen abzugrenzen, die technischen Verfahren des Datenabrufs, bzw. der Datenübernahme festzulegen und Wege zur dauerhaften Archivierung zu finden. Wichtig sind in diesem Zusammenhang aber auch die Festlegungen hinsichtlich des Zugriffs auf die Publikationen.

External Debt Profile and its Sustainability: Evidence from East African Countries
Creators: name: Tolasa, Alemayehu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The aim of this paper is to empirically examine the sustainability of East African countries external debt over the period 2000-2016. For this purpose, this empirical analysis makes a use of various unit root test (i.e., univariate unit root test, panel unit root test and co-integration) test by taking the possibility of cross sectional dependence in to account. The intertemporal government budget constraint provides a test based on both stationarity and the cointegration relation between government revenues and expenditure including interest payments on external debt. Tests for stationarity and then cointegration between revenue and expenditure are based on recently developed panel data methods that offer increased power over existing time series techniques. Unlike existing panel studies on this topic, this study utilizes techniques that enable the examination of sustainability for individual panel members. The first stage of the investigation relies on a novel approach to unit root testing whereby tests for stationarity are conducted within a seemingly unrelated regression framework. The second stage involves the estimation of the long-run relationship between the revenue and expenditure by a range of recently developed panel data techniques advocated by Pedroni. Using a panel of nine EAC countries for the study period 2000-2016, the results from these techniques suggest that sustainability is present in four countries at most (Kenya, Eritrea, Sudan and Tanzania). These results confirmed with existing individual unit root and cointegration tests that indicate external sustainability for aforementioned countries. The study deduces that the external debt of EAC countries is unsustainable or weakly sustainable so they should exploit their domestic resources instead of going for the foreign resources and encourage saving and investment environment in their countries

description: Background: The Coronavirus disease 2019 (COVID-19) has affected more than two hundred million individuals and many risk factors for increased mortality and morbidity in COVID-19 have defined. There are many studies evaluating the effect of immunosuppressants used in inflammatory rheumatic diseases in the course of COVID-19. (1,2) However, fewer data are available on the course of COVID-19 in patients with Takayasu arteritis (TAK). This study evaluated the characteristics and outcomes of TAK patients with COVID-19. Methods: A phone survey was conducted among TAK patients that are followed up in our clinic between February 2021 and March 2021. All patients were asked whether they were diagnosed as COVID-19 during the pandemic. The patients who had a history of confirmed COVID-19 were asked about the symptoms, hospitalization status and the treatment received for COVID-19. Information about their chronic diseases were obtained from the patient files. Results: Among 118 TAK patients, 15 had COVID-19 infection during the first year of pandemic, 13 of them were female and mean age was 42,5 ± 12,0 years. None of the patients had been vaccinated before the diagnosis of COVID-19. Nine of the patients were taking prednisone therapy and 3 of them were taking moderate to high doses of glucocorticoids during the infection period. Twelve patients were taking conventionally synthetic disease-modifying antirheumatic drugs (csDMARDs), 7 patients were taking biological disease-modifying antirheumatic drugs (bDMARDs), and 5 patients were taking a combination of csDMARD and bDMARD therapy when they were diagnosed with COVID-19. Two patients were hospitalized; one of them required nasal oxygen support and discharged after 5 days. The other patient was 61 years old and had multipl comorbidities and had admitted to intensive care unit for 5 days. One patient who had a mild COVID-19 disease had pulmonary thromboembolism 2 weeks after the infection and his symptoms resolved after starting anticoagulation therapy. All of the patients fully recovered and had no mortality related to COVID-19. Conclusions: To our knowledge, this is the largest cohort reporting the course of COVID-19 in TAK patients. Our data suggest that there is no increased risk for morbidity or mortality related to COVID-19 in TAK patients. Disclosures: None.

description: In terms of vitality, the Hadza language has been classified as “vulnerable” by the UNESCO Atlas of the World’s Languages in Danger, or “endangered” by Ethnologue. All previous reports have suggested that, although the speaker population is small, intergenerational transmission was robust in most Hadza communities—that is, until recently. During fieldwork conducted in 2022, I have identified a nascent shift in language use among Hadza children below the age of eight; in all but two camps in which I visited, children ≤8 years old are primarily communicating in Swahili amongst agemates, as well as in response to older speakers. The Hadza community is aware of this language shift and many are concerned with its implications for the future. Community members have already begun grassroots efforts to combat language atrophy within the community. This presentation, therefore, will offer an update on the linguistic situation, its implications for Hadza language vitality, and detail some community-internal and -external ethnolinguistic conservation efforts.

Seit WS 1994/95 wird systematisch in die Nutzung des Internet eingeführt. Diese Veranstaltungen, die auf stetig wachsendes Interesse aus allen Ausbildungsgängen stoßen, haben ein dreifaches Ziel: Sie sollen die Studierenden mit dem Internet konzeptionell und praktisch vertraut machen, d.h. in den Umgang mit Internet-spezifischen Software-Tools einführen und deren Nutzung selbstverständlich werden lassen. Die Studierenden sollen bei der konkreten Nutzung der Informations- und Dienstleistungsangebote im Internet Erfahrungen sammeln und so Kriterien für eine Bewertung der Möglichkeiten zur Informationsbeschaffung bzw. -vermittlung aus und über das Internet erschließen. Sie sollen die Studierenden mit dem aktiven Vermitteln derartiger Kenntnisse vertraut machen. Im Zusammenspiel dieser Ziele wird ermöglicht, daß die Studenten die Möglichkeiten und Konsequenzen des Internet für die Arbeit in BID-Einrichtungen einzuschätzen lernen und auch vor dem Hintergrund eigener Erfahrungen diese Sichtweise begründen können. Die Veranstaltungen erwarten von den Studierenden ein hohes Maß an Eigeninitiative und aktiver Beteiligung während und zwischen den Veranstaltungen. Hierdurch fördern sie zusätzlich auch die Ausbildung von Arbeitstechniken und intensivieren die Kommunikation der Studenten verschiedener Ausbildungsgänge untereinander.

description: The flavor composition of high-energy astrophysical neutrinos is a rich observable. However, present analyses cannot effectively distinguish particle showers induced by $ν_e$ versus $ν_τ$. We show that this can be accomplished by measuring the intensities of the delayed, collective light emission from muon decays and neutron captures, which are, on average, greater for $ν_τ$ than for $ν_e$. This new technique would significantly improve tests of the nature of astrophysical sources and of neutrino properties. We discuss the promising prospects for implementing it in IceCube and other detectors.

Siguiendo un marco de "desajuste espacial", se estima una ecuación de probabilidad de empleo que incluye variables que controlan las características socioeconómicas, la segregación residencial y de accesibilidad vista como tenencia de vehículo privado (moto y/o automóvil). Los datos utilizados provienen de la Gran Encuesta Integrada de Hogares 2015 del DANE. Los resultados muestran que la tenencia de automóvil tuvo un efecto significativo en la empleabilidad, especialmente para aquellos con nivel educativo básico -debido a que estos son más sensibles a las condiciones locales del mercado de trabajo que los trabajadores con nivel educativo superior-, de tal manera que contribuye a la probabilidad de que sean empleados. Por su parte, la tenencia de motocicleta resultó ser significativo para el género femenino, contribuyendo a la probabilidad de que sean empleadas.

description: We show that bipartite entanglement in a one-dimensional quantum spin model undergoing time-evolution under local Markovian environments can be frozen over time. We demonstrate this by using a number of paradigmatic quantum spin models in one dimension, including the anisotropic XY model in the presence of a uniform and an alternating transverse magnetic field (ATXY), the XXZ model, the XYZ model, and the $J_1-J_2$ model involving the next-nearest-neighbor interactions. We show that the length of the freezing interval, for a chosen pair of nearest-neighbor spins, may remain independent of the length of the spin-chain, for example, in paramagnetic phases of the ATXY model, indicating a scale-invariance. Such freezing of entanglement is found to be robust against a change in the environment temperature, presence of disorder in the system, and whether the noise is dissipative, or not dissipative. Moreover, we connect the freezing of entanglement with the propagation of information through a quantum many-body system, as considered in the Lieb-Robinson theorem. We demonstrate that the variation of the freezing duration exhibits a quadratic behavior against the distance of the nearest-neighbor spin-pair from the noise-source, obtained from exact numerical simulations, in contrast to the linear one as predicted by the Lieb-Robinson theorem.

description: The languages spoken in East Africa before the introduction of pastoralism and agriculture are little known; isolates such as Hadza and Shabo (Ch'abu) are still extant, but these are surely remnants of an earlier rich diversity that must have obtained. This study looks at words that occur in these languages of East African hunter-gatherers and also in Peripheral East Cushitic (PEC) languages (Dullay and Yaaku), which would have been spoken by some of the earliest East African pastoralists. We contend that Cushitic languages spoken by foragers such as Dahalo and Yaaku retained some vocabulary items from earlier, non-Cushitic languages. PEC languages spoken by pastoralists also include some lexical items borrowed from forager languages, i.e. adstratal rather than substratal borrowing. Contact between foragers and pastoralists was not a one-time event; loans between West Rift and Hadza also occur, as has already been well-attested in the literature.

description: In vielen wissenschaftlichen Diskussionen ist das Internet zu einem heftig umkämpften Schlagwort geworden. Häufig bleiben dabei die tatsächlichen Möglichkeiten, aber auch Nachteile der wissenschaftlichen Nutzung der Datenautobahn verkannt. Der vorliegende Aufsatz möchte, focusiert auf die Sonderpädagogik, gegenwärtige ebenso wie zukünftige Anwendungsbereiche, schon existierende Angebote ebenso wie noch nicht ausgeschöpfte Nutzungspotentiale kritisch beleuchten. Entsprechend ist die Recherche nach klassischer, d. h. papierner Literatur in Suchsystemen und Datenbanken im Internet ebenso zu thematisieren, wie die Recherche nach unmittelbar anklickbaren elektronischen Volltexten - eine Dualität, der es bei Einzelveröffentlichungen, aber auch bei Zeitschriftenangeboten des sonderpädagogischen Kontextes nachzugehen gilt. Darüber hinaus wird das eigene wissenschaftliche Publizieren im Internet vorgestellt.

description: Das Internet, entstanden aus dem militärischen ARPANET, hat sich zu einem weltumspannenden Computernetz entwickelt. Von den traditionellen Internetdiensten wie EMail oder FTP gingen die Entwicklungen hin zu ansprechenderen Informationssystemen und interaktiven Diensten. Seit Einführung des WWW hat das Internet einen enormen Zuwachs an Anwendern erfahren. Dieser rasante Erfolg des WWW bereitet jedoch auch Probleme, da es nicht dafür ausgelegt war, solch große Datenmengen und komplexe Anwendungen zu beherrschen. Hier sind nun Weiterenwicklungen oder Neukonzeptionen gefragt, um den wachsenden Anforderungen zu entsprechen.

description: Classic cake-cutting algorithms enable people with different preferences to divide among them a heterogeneous resource (``cake''), such that the resulting division is fair according to each agent's individual preferences. However, these algorithms either ignore the geometry of the resource altogether, or assume it is one-dimensional. In practice, it is often required to divide multi-dimensional resources, such as land-estates or advertisement spaces in print or electronic media. In such cases, the geometric shape of the allotted piece is of crucial importance. For example, when building houses or designing advertisements, in order to be useful, the allotments should be squares or rectangles with bounded aspect-ratio. We thus introduce the problem of fair land division --- fair division of a multi-dimensional resource wherein the allocated piece must have a pre-specified geometric shape. We present constructive division algorithms that satisfy the two most prominent fairness criteria, namely envy-freeness and proportionality. In settings where proportionality cannot be achieved due to the geometric constraints, our algorithms provide a partially-proportional division, guaranteeing that the fraction allocated to each agent be at least a certain positive constant. We prove that in many natural settings the envy-freeness requirement is compatible with the best attainable partial-proportionality.
description: A preliminary version named 'Envy-free cake-cutting in two dimensions' appeared in the proceedings of AAAI 2015 (https://www.aaai.org/ocs/index.php/AAAI/AAAI15/paper/viewPaper/9656). The main additions here are: (a) handling multi-dimensional resources of arbitrary shape rather than just rectangles, (b) handling an arbitrary number n of agents rather than just 2 or 3, (c) rewriting most proofs

Desde ese punto de vista, la ciudadanía más allá de ser un concepto político contractual entre la tradición hispánica cristiana como forma de control y la nueva ética moderna comercial e industrial promovida por la instrucción pública y privada, para instruir y formar los caracteres del hombre perfecto.
