description: In Befragungen zeigt sich regelmäßig der Wunsch von Verbrauchern, über die Herkunft von Lebensmitteln informiert zu werden. Unklar bleibt dabei bislang sowohl in der Literatur als auch in der Praxis, wie eine Region zu definieren und was unter regionalen Lebensmitteln zu verstehen ist. Ebenso konnte in Studien nicht abschließend das Verbraucherverständnis dieser Begrifflichkeiten geklärt werden und ob sich diesbezüglich Unterschiede zwischen verschiedenen Verbrauchergruppen ergeben. Beispielhaft geht die vorliegende empirische Untersuchung der Frage nach, inwiefern Unterschiede zwischen west- und ostdeutscher Bevölkerung im Hinblick auf die Wahrnehmung regionaler Produkte und damit zusammenhängende Auswirkungen auf das Einkaufsverhalten bestehen.Es zeigt sich, dass Konsumenten in Ost und West gleichermaßen die regionale Herkunft als wichtiges Kriterium beim Kauf von Lebensmitteln einstufen; ebenso homogen zeigen sich die Befragten beider Gebiete bei den Assoziationen, die mit dem Begriff eines regionalen Lebensmittels verbunden werden. Insofern kann eine Angleichung zwischen Ost und West konstatiert werden, was die Bedeutung der eigenen Region anbelangt. Damit einher geht jedoch eine Rückbesinnung auf kleinräumige Gebiete, die einer gesamtdeutschen Sichtweise entgegensteht.Aus den Ergebnissen der vorliegenden Studie lassen sich darüber hinaus Empfehlungen für die Kennzeichnung regionaler Lebensmittel ableiten: während bei ostdeutschen Verbrauchern der Bezug zur Heimat bei der Kommunikation im Vordergrund stehen sollte, sollte die Ansprache im Westen tendenziell auf einer konkreten Distanzangabe basieren. Zudem ist Frauen und den Teilen der Bevölkerung mit einem niedrigen Bildungsabschluss die regionale Herkunft beim Einkauf von Lebensmitteln wichtiger als anderen Verbrauchergruppen.

description: In our earlier papers we constructed examples of 2-dimensional nonaspherical simply-connected cell-like Peano continua, called {\sl Snake space}. In the sequel we introduced the functor $SC(-,-)$ defined on the category of all spaces with base points and continuous mappings. For the circle $S^1$, the space $SC(S^1, \ast)$ is a Snake space. In the present paper we study the higher-dimensional homology and homotopy properties of the spaces $SC(Z, \ast)$ for any path-connected compact spaces $Z$.

description: We examine the behavior of the leading Regge trajectory of the open bosonic string in a uniform electromagnetic background and present a consistent set of Fierz-Pauli conditions for these symmetric tensors that generalizes the Argyres-Nappi spin-2 result. These equations indicate that String Theory does bypass the Velo-Zwanziger problem, i.e. the loss of causality experienced by a massive high-spin field minimally coupled to electromagnetism. Moreover, we provide some evidence that only the first Regge trajectory can be described in isolation and show that the open-string spectrum is free of ghosts in weak constant backgrounds. Finally, we comment on the roles of the critical dimension and of the gyromagnetic ratio.

description: Based on a data set obtained in a dental longitudinal study, conducted in Flanders (Belgium), the joint time to caries distribution of permanent first molars was modeled as a function of covariates. This involves an analysis of multivariate continuous doubly-interval-censored data since: (i) the emergence time of a tooth and the time it experiences caries were recorded yearly, and (ii) events on teeth of the same child are dependent. To model the joint distribution of the emergence times and the times to caries, we propose a dependent Bayesian semiparametric model. A major feature of the proposed approach is that survival curves can be estimated without imposing assumptions such as proportional hazards, additive hazards, proportional odds or accelerated failure time.

description: We have carried out high-field resistivity measurements up to 27\,T in EuFe$_2$As$_2$ at $P$\,=\,2.5\,GPa, a virtually optimal pressure for the $P$-induced superconductivity, where $T_\mathrm{c}$\,=\,30\,K. The $B_\mathrm{c2}-T_\mathrm{c}$ phase diagram has been constructed in a wide temperature range with a minimum temperature of 1.6 K ($\approx 0.05 \times T_\mathrm{c}$), for both $B \parallel ab$ ($B_\mathrm{c2}^\mathrm{ab}$) and $B \parallel c$ ($B_\mathrm{c2}^\mathrm{c}$). The upper critical fields $B_\mathrm{c2}^\mathrm{ab}$(0) and $B_\mathrm{c2}^\mathrm{c}$(0), determined by the onset of resistive transitions, are 25 T and 22 T, respectively, which are significantly smaller than those of other Fe-based superconductors with similar values of $T_\mathrm{c}$. The small $B_\mathrm{c2}(0)$ values and the $B_\mathrm{c2}(T)$ curves with positive curvature around 20 K can be explained by a multiple pair-breaking model that includes the exchange field due to the magnetic Eu$^{2+}$ moments. The anisotropy parameter, $Γ=B_\mathrm{c2}^{ab}/B_\mathrm{c2}^{c}$, in EuFe$_2$As$_2$ at low temperatures is comparable to that of other "122" Fe-based systems.

Investigation and characterization of microlenses for imaging reception in indoor optical wireless communications
Creators: name: Guerrero, Daniel
Publisher: name: University of British Columbia
Year: 2020

description: The gain in popularity of optical wireless technologies over the past decade is the start of a revolution in optical technology. While we have seen commercial optical communication systems firmly establish themselves over the past decades, through the use of optical fibres for point-to-point optical communications, we are now beginning to see the emergence of mobile optical wireless technologies. Such technologies typically use portable imaging receivers and fixed indoor transmitters, such that data can be piggybacked onto lighting from distributed light emitting diodes (LEDs) within the room. These optical wireless communication systems can potentially provide high-speed optical communications with wireless mobility. However, such systems have practical challenges for the imaging receivers, in that they are typically implemented with bulky (typically centimetre-scale) optical elements with narrow field-of-view characteristics. The proposed work addresses these practical challenges by introducing microlens technologies that are suited for optical wireless implementations. It is shown that the implemented microlenses can enable compact imaging, with strong signal levels and wide field-of-view characteristics.
Canonical Relational Quantum Mechanics from Information Theory
Creators: name: Munkhammar, Joakim
Publisher: name: arXiv
Year: 2011
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: In this paper we construct a theory of quantum mechanics based on Shannon information theory. We define a few principles regarding information-based frames of reference, including explicitly the concept of information covariance, and show how an ensemble of all possible physical states can be setup on the basis of the accessible information in the local frame of reference. In the next step the Bayesian principle of maximum entropy is utilized in order to constrain the dynamics. We then show, with the aid of Lisi's universal action reservoir approach, that the dynamics is equivalent to that of quantum mechanics. Thereby we show that quantum mechanics emerges when classical physics is subject to incomplete information. We also show that the proposed theory is relational and that it in fact is a path integral version of Rovelli's relational quantum mechanics. Furthermore we give a discussion on the relation between the proposed theory and quantum mechanics, in particular the role of observation and correspondence to classical physics is addressed. In addition to this we derive a general form of entropy associated with the information covariance of the local reference frame. Finally we give a discussion and some open problems.

description: Die moderne Landwirtschaft muss die wachsende Nachfrage nach qualitativ hochwertigen und sicheren Agrarprodukten für die Ernährung von Menschen und Nutztieren, für die stoffliche Verwertung in industriellen Prozessen sowie für die Gewinnung von Energie sicherstellen. Gleichzeitig muss sie die Anforderungen an den Schutz des Klimas und der Umwelt, einschließlich Boden und Wasser, sowie den Tierschutz erfüllen.
Dies löst unweigerlich eine Fülle von Stoffströmen in die Umwelt aus, die in der Öffentlichkeit zum Teil kontrovers diskutiert werden. Stichworte wie Stickstoff, Phosphar, Schwermetalle, Grundwasser, Treibhausgase und Gülleverordnung sind in diesem Zusammenhang häufig zu hören.
Das 5. Agrarwissenschaftliche Symposium "Agrarische Stoffkreisläufe" soll diesen Themenbereich aus den Blickwinkeln des Nährstoffmanagements, des Umweltschutzes und der Ressourceneffizienz aufgreifen und mit Hilfe fachkompetenter Referenten detailliert betrachten.

Subjects: Exoplanets

description: Ever since the discovery of the first exoplanet in 1995, more than 4000 exoplanets have been discovered so far. The majority of the exoplanets were discovered by transit and radial velocity methods. And the numbers are only likely to increase prominently, with the number of people (space organizations, citizen scientists, amateur astronomers, etc.) searching for new exoplanets. This passion towards exoplanets among the scientific community is mainly triggered by the possibility of finding an Earth-like world among the others. Our search for earth-like planets and intelligent life has given us insights about the planets that we are never aware of. We have detected a wide range of exoplanets including;- Super-Earths, Hot Jupiters, Mini Neptunes, Hot Earths, and many more. Overall these years of search for Earth-like planets astronomers have also come across many unorthodox exoplanets. In this paper, we study some of these non-conventional exoplanets and try to understand what makes them so strange. After years of studying our solar system and other-planet systems, we have a fair idea of planet formations. But the planets which we focus on here defies most of these ideas and makes us question our understanding of the planet formations. Studying these strange exoplanets can help us understand more about planet formation all over the universe.

description: Genus Acarohelcon van Achterberg et Chen, nov.
(Fig. 3)
 Type species: Acarohelcon varicolor sp. nov.
 Etymology. Gender: masculine.
 Diagnosis. Occipital carina distinctly curved above base of mandible, nearly rectangularly angled with hypostomal carina and connected to hypostomal carina distinctly above base of mandible, resulting in a narrow combined non-lamelliform carina (Fig. 3 F) and not protruding below base of mandible but adpressed to base of mandible; median lamella of frons absent, only with a weakly developed median carina or crest; frontal depression present but shallow posteriorly; propleuron convex and punctate or rugose; mesopleuron in front of prepectal carina oblique, gradually narrowed (Fig. 3 B); prepectal carina present medio-ventrally; second submarginal cell of fore wing medium-sized (Fig. 3 A); vein a of fore wing only pigmented; marginal cell of hind wing distinctly widened apically (Fig. 3 A); hind coxa with baso-ventral tubercle; hind femur simple, wavy rugose ventrally, rather slender and hardly or not serrate in lateral view (Fig. 3 D); basal part of first metasomal sternite longer than wide and basally smooth, separated from tergite; second metasomal suture between first and second tergites narrow and shallow; second tergite coarsely sculptured and third tergite smooth; fourth-sixth metasomal tergites of ♀ well exposed behind third tergite; apex of ovipositor sheath with short erect setae but remainder normally obliquely setose.
 Notes. Only the type species known from Oriental China (Guangxi). The new genus is similar to the Australian genus Parahelcon Kokujev, 1901, if the character of the ventrally sculptured hind femur is ignored. It differs from Parahelcon by the widened marginal cell of the hind wing (distinctly narrowed in Parahelcon), vein a of fore wing only pigmented (sclerotized basally) and the occipital flange narrow and adpressed to the base of the mandible (larger and protruding below base of the mandible).

description: For two coupled Anderson impurities, two energy scales are present to characterize the evolution from local moment state of the impurities to either of the inter-impurity singlet or the Kondo singlet ground states. The high energy scale is found to deviate from the single-ion Kondo temperature and rather scales as Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction when it becomes dominant. We find that the scaling behavior and the associated physical properties of this scale are consistent with those of a coherence scale defined in heavy fermion systems.

Seeing Hypersexual Disorder for the Disease it Is (Pilot Study)
Creators: name: Wills, Winfred
Publisher: name: figshare
Year: 2017
Subjects: subject: 111714 Mental Health
subject: FOS: Health sciences

description: The American Psychological Association (APA) excluded Hypersexual Disorder from the Diagnostic Statistical Manual Volume 5 (DSM V) because according to them there was not significant empirical scientific data to include such a disease in the DSM 5. However, the researcher found this contention vague and unsettling. Therefore, using a grounded theory approach, in which the researcher made no assumptions and collected data from two participants (Participant A1 and Participant D2). They were selected by meeting stringent criteria and belonging to a sexual addiction support group in the Vintage Parish District. The researcher was further careful to attend all of the groups in this district, the researcher was able to find that on average 20 people are members in the groups. Thus, the sample size of 2 is 10% of the actual size.
Based on the information contained in this pilot study information contained in this study, the researcher found that sexually compulsive behaviors and their frequency positively correlate moderately with the participants' perceived life functioning impairment. The study also found that there was a strong positive correlation that was statistically significant between the participants' Wheel of Integrative Happiness Scores before and after Life Coaching sessions and their life functioning survey scores before and after sessions were done. The study also considered the fact that according to the DSM V, Hypersexual Disorder meets four of the APA's own criteria for Sedative, Hypnotic, or Anxiolytic Disorder. Showing 4 symptoms of the disorder is considered a moderate addiction.
This shows promise in future research and the researcher finds that the study will need to be done again using a greater number of participants. However, preliminary results have led the researcher to conclude that the APA was incorrect in excluding Hyersexual Disorder from the DSM V. Instead it is the theory of the researcher that Hypersexual Disorder is a mental illness that is mitigated in part by the use of Life Coaching Techniques.

description: Seit dem Schuljahr 2014/15 wird die mündliche Reifeprüfung in Österreichs Allgemeinbildenden höheren Schulen verpflichtend kompetenzorientiert abgehalten. Anstatt wie bisher Reifeprüfungsfragen zu stellen, die von Schüler*innen hauptsächlich die Reproduktion von erworbenem Fachwissen verlangen, müssen Biologielehrer*innen nun Prüfungsaufgaben entwickeln, die den Kompetenzerwerb bei Schüler*innen sichtbar machen; d.h. die Fähigkeit, ihr Fachwissen in komplexen, lebensweltlichen Problemsituationen anwenden zu können. Studien aus Deutschland und der Schweiz haben bereits gezeigt, dass Biologielehrer*innen damit große Schwierigkeiten haben. In Österreich wird dies hier erstmals untersucht. Dazu wurden 100 Reifeprüfungsaufgaben, die von Biologielehrer*innen aus ganz Österreich im Zeitraum 2014-2016 entwickelt wurden, mittels eines Kategoriensystems quantitativ analysiert. Die Ergebnisse zeigen, dass der Großteil der Prüfungsaufgaben lediglich die Reproduktion oder Reorganisation von Fakten- bzw. Konzeptwissen in innerfachlichen Anwendung-kontexten verlangen. Deutlich seltener sind Aufgaben, die einen tatsächlichen Transfer des erlernten Wissens auf neue Anwendungssituationen bzw. im Umgang mit komplexen Problemsituationen erfordern. Die Erkenntnisse aus der Studie wurden dazu verwendet, Handreichungen zu entwickeln, die Biologielehrer*innen gezielt bei der Entwicklung von kompetenzorientierten Prüfungsaufgaben unterstützen.

description: Planck is expected to answer crucial questions on the early Universe, but it also provides further understanding on anomalous microwave emission. Electric dipole emission from spinning dust grains continues to be the favored interpretation of anomalous microwave emission. In this paper, we present a method to calculate the rotational emission from small grains of irregular shape with moments of inertia $I_{1}> I_{2}> I_{3}$. We show that a torque-free rotating irregular grain with a given angular momentum radiates at multiple frequency modes. The resulting spinning dust spectrum has peak frequency and emissivity increasing with the degree of grain shape irregularity, which is defined by $I_{1}:I_{2}:I_{3}$. We discuss how the orientation of dipole moment $\bmu$ in body coordinates affects the spinning dust spectrum for different regimes of internal thermal fluctuations. We show that the spinning dust emissivity for the case of strong thermal fluctuations is less sensitive to the orientation of $\bmu$ than in the case of weak thermal fluctuations. We calculate spinning dust spectra for a range of gas density and dipole moment. The effect of compressible turbulence on spinning dust emission intensity is investigated. We show that the emission intensity in a turbulent medium increases by a factor from 1.2-1.4 relative to that in a uniform medium, as sonic Mach number $M_{s}$ increases from 2-7. Finally, spinning dust parameters are constrained by fitting our improved model to five-year {\it Wilkinson Microwave Anisotropy Probe} cross-correlation foreground spectra, for both the H$α$-correlated and 100 $μ$m-correlated emission spectra.

More than the silence of rifles : Guatemalan rebel combatants’ perspectives on the eve of peace
Creators: name: Stewart, Stephen Robin Peter
Publisher: name: University of British Columbia
Year: 2020

description: This thesis analyses interviews with 13 guerrilla combatants originally conducted in early 1997, while I was a journalist with the CERIGUA news agency covering the Guatemalan armed conflict, the Peace Accords and the demobilization and reintegration into civil society of Guatemalan National Revolutionary Unity (URNG) fighters. The work gathers the testimonies of the guerrillas, including their motivations for joining the insurgency, experiences in the guerrilla, and feelings regarding the end of the armed conflict and their pending reintegration into Guatemalan society. I compare what the URNG combatants expressed in these interviews with other research regarding the 36-year conflict and especially studies documenting the experience of demobilized URNG members a decade or more after their reintegration into Guatemalan civil society. Based on this research, the thesis argues that, contrary to what is promoted in some Disarmament, Demobilization and Reintegration (DDR) literature, in the Guatemalan experience collective reintegration proved more successful than individualized reintegration, and should have been provided to a much large number of former combatants. In this research, successful reintegration is interpreted as economic and social well-being, as well as the political and social engagement of the former combatants in broader Guatemalan society, particularly engagement aimed at addressing the factors that originally gave rise to the armed conflict. Special attention is paid to these criteria in the reintegration of female former combatants.

description: We study the formation of a Bose-Einstein condensate in a cigar-shaped three-dimensional harmonic trap, induced by the controlled addition of an attractive "dimple" potential along the weak axis. In this manner we are able to induce condensation without cooling due to a localized increase in the phase space density. We perform a quantitative analysis of the thermodynamic transformation in both the sudden and adiabatic regimes for a range of dimple widths and depths. We find good agreement with equilibrium calculations based on self-consistent semiclassical Hartree-Fock theory describing the condensate and thermal cloud. We observe there is an optimal dimple depth that results in a maximum in the condensate fraction. We also study the non-equilibrium dynamics of condensate formation in the sudden turn-on regime, finding good agreement for the observed time dependence of the condensate fraction with calculations based on quantum kinetic theory.

description: As Artificial Intelligence in Education (AIED) becomes integrated into post-digital educational spaces, examining how these technologies influence student and teacher agency is imperative. AI-mediated education raises the question: How does AI impact student and teacher autonomy and self-efficacy? This paper aims to (1) contextualize AIED as a critical transformation driven by developments in digital technology and automation, (2) address how the paradigm of post-digital educational spaces can contribute to a deeper understanding of the impact of AIED on student and teacher agency, and (3) offer insights on potential future directions in teacher training and teaching and learning. The concept ofpost-agencyis presented as a means of articulating that as AI becomes an integral part of education, it will transform how individuals acquire, share, and apply knowledge, ultimately reshaping the notion of agency in teaching and learning. This paper provides students' and an educator's perspectives on using AI tools in a music teacher education course on songwriting, composition, and production at a German university. Amidst the ongoing digitalization and widespread integration of AI in society, this paper strives to contribute to developing informed and ethically grounded educational practices in the post-digital age.

description: In this work, the simulation possibilities of transient magnetic fields are investigated. For this purpose, an experimental setup is established to compare the simulation results with actual measurement data. The experimental set-up consists of two coils, which are placed on two U-shaped iron cores. These cores are then brought together to form two air-gaps. These two gaps are used for measurement and the optional insertion of samples. The simulations are carried out with the finite element method (FEM) program ANSYS Maxwell 19R3. In the first experiments, static simulations and measurements are compared to verify the validity of the available material data and the simulation techniques, especially the symmetry considerations, excitations of the coils, and boundary conditions. The static simulations show two main sources of uncertainty. The B-H curve of the core material used in the simulations and the air-gap distance uncertainty. After validating the simulations with the static measurements, transient experiments are performed. In these experiments, the qualitative agreement of the simulation and measurement, as well as the characteristic rise times are compared. The experiments show a decisive influence of the considered loss mechanisms on the agreement of the simulation results with the measurements. Therefore, several simulations with different loss mechanisms are performed. Finally, also the simulation capability including a material sample in the upper gap is investigated. Therefore, the conformity of the relative change of the measurement and the simulation is compared. In the experiments a good simulation capability within a 5% error bar is seen. The main difficulty of this work represents the uncertainty due to the available material data. It is assumed, that with more accurate material data the error can be reduced significantly.

description: We present an overview of SPICA, the Space Infrared Telescope for Cosmology and Astrophysics, a world-class space observatory optimized for mid- and far-IR astronomy (from 5 to ~210um) with a cryogenically cooled ~3.2m telescope (<6 K). Its high spatial resolution and unprecedented sensitivity in both photometry and spectroscopy modes will enable us to address a number of key problems in astronomy. SPICA's large, cold aperture will provide a two order of magnitude sensitivity advantage over current far-IR facilities (lambda>30 um wavelength). In the present design, SPICA will carry mid-IR camera, spectrometers and coronagraph (by JAXA institutes) and a far-IR imager FTS-spectrometer, SAFARI (~34-210 um, provided by an European/Canadian consortium lead by SRON). Complementary instruments such as a far-IR/submm spectrometer (proposed by NASA) are also being discussed. SPICA will be the only space observatory of its era to bridge the far-IR wavelength gap between JWST and ALMA, and carry out unique science not achievable at visible or submm wavelengths. In this contribution we summarize some of the scientific advances that will be made possible by the large increase in sensitivity compared to previous infrared space missions.

description: This study focuses on interaction of individuals with the service environment. In this context, the role of environmental variables, service providers, other consumers and organizations/systems in this interaction were discussed. Understanding this role is important for both researchers and practitioners. Particularly, in a service environment where instantaneous and intensive interaction is a concern, to evaluate the effects of environmental variables would be enable to predict the possible negativeness of subsequent experiences and to constitute convenient environment for the service encounter.
Risikotragfähigkeit im Risikomanagementprozess: Konzeption und  praktische Anwendung eines kennzahlengestützten Scoringsystems zur Analyse landwirtschaftlicher Familienbetriebe
Creators: name: Theuvsen, Ludwig

description: Das Thema Risikomanagement findet aufgrund seiner zunehmenden Relevanz heute in Forschung, Literatur und landwirtschaftlicher Beratung breite Aufmerksamkeit. Allerdings ließen bisherige Konzepte den Aspekt der (monetären) Risikotragfähigkeit, also der finanziellen Widerstandsfähigkeit landwirtschaftlicher Betriebe, weitestgehend unberücksichtigt, obwohl sie einen deutlichen Einfluss auf die Risikoeinschätzung selbst und insbesondere auf die Auswahl geeigneter Instrumente zur effektiven Steuerung von Risiken (und Chancen) ausübt.Der vorliegende Beitrag verknüpft den klassischen, vierstufigen Ansatz zur Systematisierung des Risikomanagementprozesses (Risikoidentifikation, -bewertung, -steuerung und -kontrolle) über die in der Praxis etablierte Darstellungsform der Risikoportfolios mit einer in der landwirtschaftlichen Praxis anwendbaren Methode zur (Selbst-)Bestimmung der Risikotragfähigkeit durch landwirtschaftliche Betriebsleiter, die auf prägnanten Zahlen aus dem betriebswirtschaftlichen Jahresabschluss basiert. Diskutiert werden acht Schlüsselkennzahlen, die die finanzielle Tragfähigkeit eines Betriebs aus der Risikoperspektive zuverlässig abbilden, in der Praxis gebräuchlich sind und bei landwirtschaftlichen Familienbetrieben sowohl betriebliche als auch private Elemente einbeziehen.Das Konzept wird durch eine überregionale Fallstudienanalyse in seiner Praxistauglichkeit bestätigt und anhand des umfangreichen Datenbestands des Testbetriebsnetzes des Bundesministeriums für Ernährung und Landwirtschaft (BMEL) validiert. Modellrechnungen für einen Ackerbaubetrieb, je einen spezialisierten Schweinemast- und Milchviehbetrieb sowie einen Verbundbetrieb runden den Beitrag ab und zeigen praktische Möglichkeiten zur Risikosteuerung auf, die vorhandene Ansätze zum planvollen Umgang mit Risiken sinnvoll ergänzen.
