description: Die empirische Wende, die sich vor dem Hintergrund einer stärkeren Output-Orientierung im Bildungswesen in allen Fachdidaktiken vollzieht, bleibt auch in der Fremdsprachendidaktik und Fremdsprachenforschung nicht ohne Widerhall. In den letzten Jahren wurden zunehmend Projekte realisiert, die unter Nutzung der vorhandenen theoretischen Modelle und curricularen Vorarbeiten einen empirischen Zugriff auf das Fremdsprachenlernen im Schulunterricht realisieren. Das Projekt DESI (Deutsch-Englisch-Schülerleistungen International; Beck & Klieme 2007; DESIKonsortium 2008) kann innerhalb der Fremdsprachendidaktik vielleicht als Startschuss für repräsentative empirische Vorstöße gewertet werden. Das von der Kultusministerkonferenz im Jahre 2001 in Auftrag gegebene Projekt untersuchte im Rahmen kooperativer Zusammenarbeit von Fachdidaktikern, pädagogischen Psychologen und DiagnostikExperten systematisch die Realität des Englisch- und Deutschunterrichts in der 9. Klasse. Der DESI-Studie folgten weitere empirische Arbeiten in den Fremdsprachendidaktiken und nicht zuletzt eine systematische Ausdifferenzierung von Leistungserwartungen in der Schule im Rahmen der Definition von Bildungsstandards für Englisch als Fremdsprache (Kultusministerkonferenz 2003; Rupp, Vock, Harsch & Köller 2008). Weiterhin gab es in den letzten Jahren international ausgerichtete Bemühungen, empirische Vergleiche von Fremdsprachenkompetenzen zwischen Sprachlernern aus verschiedenen Staaten zu ermöglichen. Das Projekt EBAFLS (European Bank of Anchor Items for Foreign Language Skills, vgl. Jurecka 2010) stellt einen Schritt hin zur Vergleichbarkeit von europäischen Sprachzertifikaten dar, teilnehmende Länder waren Deutschland, Frankreich, Luxemburg, die Niederlande, Schottland, Schweden, Spanien und Ungarn. Die systematische Einführung von Bildungsstandards seit dem Jahr 2003 einerseits und weitere Forschungsanstrengungen im Rahmen von Schulleistungsstudien, die fremdsprachliche Kompetenz einbeziehen (z.B. KESS; May 2006), begleiten und befördern die empirische Wende in den Fachdidaktiken der Fremdsprachen, die sich inzwischen in zahlreichen Forschungsarbeiten und in einer verstärkten empirischen Aktivität in verschiedenen Projekten abbildet, in die jeweils auch Nachwuchswissenschaftler involviert sind (z.B. Bayrhuber, Harms, Muszynski, Ralle, Rothgangel, Schön, Vollmer & Weigand 2011; Aguado, Schramm & Vollmer 2010).

description: We shape objects and objects in their own way, shape us. Still, despite this reciprocal relationship we humans lack awareness of the way we make and interact with our contemporary human-made material culture. Arguably, through our modern fixation with technology and ever increasing techno-centric world, we have lost the poetic aspects of products which causes a separation between us and products and could be the reason for a lack of empathy we have for our objects. The consequence is short-lived products and a growing consumer culture. Shifting our understandings of our relationship with material culture may play a role in adjusting expectations of the future and provide alternative notions of a material world. My thesis explores ways that design can help us experience a deeper engagement with objects. It does so by seeking ways that design enables us to value the objects around us through the creation of personal meaning. My research, based on actions that I conducted between May 2020 and March 2021 has been a means to consider and better understand the agency of objects, spirituality, ways to reinforce our human's natural sensibility towards objects, and design for the creation of meaning. Objects can intervene in our life by making and changing our habits, behaviors, perceptions and emotions and this fact reveals the importance of considering the quality of our communication with the world of material things. In order to explore this communication I took on an approach that embraced practice-based design processes as a way to imagine other possibilities of the design of material things. I actively used making in order to think, reflect on and investigate our connection with objects. Doing so allowed me to work in my own quiet introspective and poetic way. Throughout, my intent has not been to find solutions, but rather to ask questions and promote consideration about our perception of material culture.
title: Implications of Absentee Courtships
Creators: name: Kerr, William Rolfe
Publisher: name: Utah State University
Year: 1966

description: In our society today the progress of many courtships and engagements is interrupted by separations of varying periods of time and for various reasons. Hill (1949) found that wartime family separations cause a two-dimensional crisis constituting a hazard to the continuance of the relations hip both at the time of separation and at the time of r e union. The assumption is made that a courtship would be affected in a similar way. Blood (1963, p. 161) says,
Both partners change somewhat while they are apart. This is not due to the separation alone, however, for personality changes go on constantly. When people are together, changes are adjusted to as they occur. New interests and behavior patterns emerge so gradually that people who see each other regularly hardly realize what is happening. If the same people had been apart, the cumulative effect of the same changes would be conspicuous.. Note how parents are never so startled by their children's growth as relatives who haven't seen them for a whole year . Personality changes not only pile up during separation but also are accentuated by it. When people are together, they are exposed to similar influences . Separation inevitably involves a different environment. In the case of military service, this change is especially marked.

description: Der Titel des vorliegenden Sammelbandes gibt auf programmatische Weise das Anliegen der neun Beiträge wieder, die im Rahmen eines 2008 von der Universität Bari durchgeführten Studientages entstanden sind. So ist der Band an sich als eine interkulturelle Schnittstelle zu verstehen, und zwar nicht nur aufgrund des bikulturellen Charakters dieser Begegnung, die auch durch die zweisprachigen Abstracts zu Beginn eines jeden Beitrags und die Option, die Texte auf Deutsch bzw. Italienisch zu veröffentlichen, zum Ausdruck gebracht wird. Ebenso stellt er eine Schnittstelle im Sinne einer Begegnungsplattform dar, die einen Austausch und Dialog zwischen deutschen und italienischen GermanistInnen und DaF-ExpertInnen möglich gemacht hat. Die Beitragenden sind in unterschiedlichen deutschen und italienischen Institutionen und Arbeitsbereichen wie der Hochschule, der italienischen weiterführen den Schule, dem Goethe Institut, dem DAAD sowie der deutschen und italienischen Lehreraus- und -fortbildung beheimatet, was zur Folge hat, dass der so umfangreiche, kaum eingrenzbare Themenkomplex der Interkulturalität aus vielfältigen Perspektiven beleuchtet werden konnte.
Development of a mechanism-based correlation model to predict the effects of freezing and thawing on the stability of vesicular Dispersions
Creators: name: Francis, Sharanda
Publisher: name: Imperial College London
Year: 2018

description: The phase behaviour of aqueous dioctadecyl dimethylammonium chloride (DODAC) solutions were studied to model the stability of liquid fabric enhancers, when exposed to the environmental stresses of cooler climate regions during transportation or storage. These effects were studied using; SAXS and WAXS, 1H NMR, DOSY and polarised light microscopy, before and after freeze-thawing (FT) of the DODAC bilayers. The effects upon FT resulted in a FT induced swelling, where the magnitude of this swelling decreased with the addition of CaCl2 to the aqueous DODAC solution. Additionally, in the absence of CaCl2, the cooling properties of the bilayers resulted in a temperature shift of the Lα->Lβ’ transition from ~31 to ~35 oC after FT, instead of the two transitions given at ~31 and ~35 oC in the presence of CaCl2 after FT. This suggests that CaCl2 decreases the changes to the DODAC bilayers and properties, upon FT. The DODAC aqueous solution is studied for the addition of glycerol and an ethoxylated alcohol surfactant. Glycerol caused swelling of the DODAC bilayers and the ethoxylated alcohol surfactant caused a lateral phase separation of a spherical to planar bilayers transition. These alterations to the DODAC bilayers, minimised the differences between the bilayers before and after FT. Also, it was shown that small unilamellar vesicles promoted the Lα->Lβ’ transition temperature shift from ~31 to ~35 oC and a spherical->planar bilayers transition, after FT. The freezing behaviour of the DODAC bilayers were observed as a cooling induced dehydration which took place after the Lα->Lβ’ phase transition instead of ice formation in the bulk water phase, at high pressure and low temperature. This resulted in a metastable freezing state with tilted bilayers, at ~ -2.0 oC which did not lead to a transition into the Lc phase until incubation at -18 oC. The effects upon thawing showed a lack of osmotic responsiveness between -5.0 and 15 oC, and an influx of water at 20 oC resulted in greater swelling of the DODAC bilayers than before FT.

description: Mit über 1000 Seiten und annähernd zwei Kilogramm gehört das Deutsche Aussprachewörterbuch (DAWB) sicherlich zu den Schwergewichten von Büchern, die sich in den Regalen von Forschern und Lehrenden entdecken lassen. Das Wörterverzeichnis beinhaltet auf beeindruckenden 793 Seiten rund 150.000 Stichwörter. Aber auch die 281 Seiten des Einführungsteils sind von gewaltigem Ausmaß, und groß ist auch die Anzahl an Bearbeitern. Somit ist das DAWB umfangreicher als die beiden anderen Aussprachewörterbücher des Deutschen, die heutzutage in Gebrauch sind: das Aussprachewörterbuch (Band 6) des Duden-Verlags (Mangold, 2005) und Siebs Deutsche Aussprache (1969).
Search for Eγ ≥ 5*10^13 eV γ-Ray Transiens Through the BAKSAN and EAS-TOP Correlated Data
Creators: name: BAKSAN And EAS-TOP Collaborations
Publisher: name: INFN Open Access Repository
Year: 2000

description: A search for transient point sources of ultra-high-energy (UHE) γ-rays has been performed, based on the correlation of two extensive air shower arrays, BAKSAN (North Caucasus, 1700 m a.s.l., BAKSAN Neutrino Observatory, Russia) and EAS-TOP (Campo Imperatore, 2005 a.s.l., Laboratori Nazionali del Gran Sasso, Italy), which are located at very similar latitudes ( φ≈43° N), and separated in longitude by Δλ≈33.7°. The search has been conducted at primary energy Eγ⩾5×10 13 eV on the time scale of a daily source transit over the sky, observable in the northern hemisphere (19° < δ < 69°), and for three sources, namely the Crab Nebula, Markarian 421 and Markarian 501, observed at TeV energies by atmospheric Cherenkov detectors. The stability of the single detectors has been studied and verified up to high significance level. No coincident excess, not compatible with the expectations from statistical fluctuations, has been observed. The obtained upper limits to the rate of transient events, nγ, at 90% c.l., are concerning the sky survey, in the declination band corresponding to the zenith, n γ/(Ωt) <12 /(yr sr) with Φγ( Eγ>5×10 13 eV)>2.0×10 -11 cm -2 s -1 and duration Δt < 8 h; concerning the candidate sources, e.g., for Markarian 421: nγ/ t < 7.7/yr with Φγ( Eγ>5×10 13 eV)>1.3×10 -11 cm -2 s -1 and Δt < 7.5 h.A coincident episode from Markarian 421, observed on 15 January, 1994, with expected chance imitation rate nch= 0.01 is discussed.
A Unified Algorithm for Accelerating Edit-Distance Computation via Text-Compression

description: We present a unified framework for accelerating edit-distance computation between two compressible strings using straight-line programs. For two strings of total length $N$ having straight-line program representations of total size $n$, we provide an algorithm running in $O(n^{1.4}N^{1.2})$ time for computing the edit-distance of these two strings under any rational scoring function, and an $O(n^{1.34}N^{1.34})$ time algorithm for arbitrary scoring functions. This improves on a recent algorithm of Tiskin that runs in $O(nN^{1.5})$ time, and works only for rational scoring functions. Also, in the last part of the paper, we show how the classical four-russians technique can be incorporated into our SLP edit-distance scheme, giving us a simple $Ω(\lg N)$ speed-up in the case of arbitrary scoring functions, for any pair of strings.
Law and Order Risks in Papua New Guinea: Perceptions and Strategies

Year: 2000

description: The breakdown of law and order reflects complex social and economic issues. Papua New Guinea is undergoing rapid transition, resulting in a breakdown of traditional social controls. Rural areas lack the services and opportunities available in urban areas, resulting in rural to urban migration. The cost of living in towns is very high and causes some people to turn to criminal activities in order to survive (GOPNG Office of National Planning and United Nations Development Programme, 1999:141). Even were reliable, accurate and timely statistics available … there are serious concerns as to the value of statistical information in determining the extent of crime in a community. Statistics must, therefore, be interpreted keeping in mind their limitations and the dangers of generalising from statistical data. Other means of measuring crime such as victimisation surveys and self-report studies may have particular relevance in PNG where it is often difficult or impossible to even report the occurrence of a crime (Banks 1997:43-44). Civil society organisations can increase the participation of the poor in the development and implementation of poverty reduction policies and programmes. In the current social unrest, we have witnessed the vital role that these organisations have played in providing some aspects of the social safety net to protect those who have been displaced. Solomon Islands in its Peace Agreement or Peace Plan must provide an enabling environment that allows institutions of civil society to be established and perform their functions freely (Liloqula, 2000:8).

Hidden Source of High Energy Neutrinos in Collapsing Galactic Nucleus
Creators: name: V.S. Berezinsky
name: V.I. Dokuchaev
Publisher: name: INFN Open Access Repository
Year: 2000

description: We propose a model of a short-lived extremely powerful source of high energy neutrinos. It is formed as a result of dynamical evolution of a galactic nucleus prior to its collapse into the massive black hole. A dense central stellar cluster in the galactic nucleus on the large stage of evolution consists of compact stars (neutron stars and stellar mass black holes). This cluster is sinked deep into the massive gas envelope produced in the collisions of the primary stellar population. The frequent collisions of remaining neutron stars in central stellar cluster result in a creation of ultrarelativistic fireballs and shock waves. They produce the rarefied cavern with external shell and quasi-stationary external shock. The particles are effectively accelerated in the cavern and, due to pp-collisions in the gas envelope, they produce high energy neutrinos. All high energy particles, except neutrinos, are absorbed in the thick envelope. Duration of active stage is ∼10 yr, the number of the sources can be ~10 per cosmological horizon. High energy neutrino signal can be detected by underground neutrino telescope with effective area ∼1 km^2.

title: Developmental Learning of Concepts of the Pre-School Child
Creators: name: Geddes, Gordon
Publisher: name: Utah State University
Year: 1967

description: A research experiment was performed in the Utah State University Child Development Laboratory on a group of pre-school children consisting of ten boys and ten girls between the ages of three and four years in an attempt to discover that teaching method which will best sustain a child's interest while teaching a foreign language in an experimental situation. The procedure involved the evaluation of three different methods. 1) German conversation in a group utilizing audio-visual aids, 2) Group singing of a German song, and 3) Telling a story in German using a flannel board with illustrations. These three methods were performed three times each over a five-week period. The results showed that there was not statistically a significant difference. The findings did show, however, that the flannelboard story sustained the interest of the group best, next the singing of a German song and the least effective was conversation in German. The results did indicate that the interest of the children dropped considerably from the first to the third time that the conversation method was performed. The interest of the children increased considerably from the first to the third time that the singing of a German Bong was performed. The interest of the children appeared to stay about the same over the three times that the flannel-board story was performed. Femininity and masculinity appear to influence the responses of children to a language-learning situation. That method which will best sustain children's interest in a language-learning situation appears to be dependent on where the children are in their familiarity with the language.
title: Psychosocial Maturity in 4-H and Non 4-H Youth
Creators: name: Young, Robert Leon
Publisher: name: Utah State University
Year: 1981

description: This study was undertaken to add to the knowledge of the psychosocial effects of the 4-H program upon its members. The objectives were to determine if 4-H involvement is associated with the psychological and social maturation of adolescent members, and to investigate how several variables such as age, urban/rural residence, and S. E. S. may help explain this relationship or lack of relationship.
To accomplish these objectives 165 youths (103 4-H, 62 non 4-H ) and one parent of each youth, responded to mail-out questionnaires, answering questions of biographical content, and items from the Psychosocial Maturity inventory. Responses were compiled and analyzed by the use of several statistical summary techniques. The author considers the following findings to be of the greatest theoretical significance.
Discriminant analysis showed 4-Hers to be different from non 4-Hers in regard to parental reports of their Interpersonal and Social Adequacy. Correlational analyses supported the notion that 4-H involvement may indeed lead to increased Social Adequacy, but showed that although Interpersonal Adequacy was higher in 4-Hers than non 4-Hers, this advantage is apparently not soley due to 4-H program effects.

description: The group-velocity of evanescent waves (in undersized waveguides, for instance) was theoretically predicted, and has been experimentally verified, to be Superluminal (υ g > c). By contrast, it is known that the precursor speed in vacuum cannot be larger than c. In this paper, by computer simulations based on Maxwell equations only, we show the existence of both phenomena. In other words, we verify the actual possibility of Superluminal group velocities, without violating the so-called (naive) Einstein causality.

Since the brane tension turns out to be proportional to Newton coupling $G$, in such a model a time variation of $G$ naturally occurs. By resorting to available bounds on the variation of $G$, the parameters of the model are constrained. The constraints coming from nucleosynthesis and CMB result to be the severest ones.

title: The Development of Empathy, Role-Taking and Listening as a Function of Preschool Experience
Creators: name: DeMarsh, Joseph P.
Publisher: name: Utah State University
Year: 1979

description: The major purpose of this investigation was to assess the potential effects of preschool education on indices of social competency. In specific, it was proposed that preschool education effects would be observed on measures of empathy, role-taking and listening.
A Solomon Four Group Design was employed to accomplish this task, using exposure of preschoolers to the Utah State University Child Development Laboratories for one quarter as the experimental treatment condition. While the typical Solomon design uses only one pretest-posttest experimental group, two groups were identified in this investigation since children were drawn from two preschool labs taught by different head teachers. Groups 3, 4, and 5 followed the conventional design, being; pretest-posttest, treatment - posttest and posttest only control groups, respectively. Experimental group subjects were randomly assigned from the child development labs, while control groups came from families living in the surrounding communities.
Developmental changes over time were observed for empathy and listening skills, but were not observed on the role-taking measure. Some evidence was presented to suggest that empathy may be primarily influenced by maturational effects, while listening skill development may be primarily influenced by preschool educational experiences . In particular , memory and auditory sequencing were found to be highly influenced by preschool influences . Further, there were also classroom differences, which indicate that either the individual teacher or classroom curriculum has specific influences which were not directly explored in this investigation. The practical significance of these findings and their relationship to existing literature was discussed.

We include nearest and next-nearest neighbor interactions and calculate exactly all pair correlation functions in a cumulant decoupling scheme. We demonstrate the importance of vacancies and interstitials in the formation of the supersolid phase. The supersolid phase is characterised by strong quantum fluctuations which are taken into account rigorously. Furthermore we confirm that the superfluid to supersolid transition is triggered by a collapsing roton minimum however is stable against spontaneously induced superflow, i.e. vortex creation.

description: The general expression of the Stern-Gerlach force is deduced for a charged particle, endowed with a magnetic moment, which travels inside a time varying magnetic field. Then, the energy integral of the Stern-Gerlach force is evaluated in the case of a particle crossing a TE rf cavity with its magnetic moment oriented in different ways with respect as the cavity axis. We shall demonstrate that appropriate choices of the cavity characteristics and of the spin orientation confirm the possibility of separating in energy the opposite spin states of a fermion beam circulating in a storage ring and, in addition, make feasible an absolute polarimeter provide that a parametric converter acting between two coupled cavities is implemented.
The "Perfect" Fluid Quenches Jets Almost Perfectly

description: The QCD matter produced in nuclear collisions at the Relativistic Heavy Ion Collider (RHIC) has been found to have a very low shear viscosity, which is close to the lower bound allowed by unitarity. The matter has also been found to strongly suppress the emission of energetic hadrons. This phenomenon, called "jet quenching" is interpreted to be the result of a large energy loss by the precursor parton on its path through the dense matter, primarily due to gluon radiation. I discuss how the two phenomena are related. The RHIC data suggest, in some scenarios of jet quenching, that the quark-gluon plasma created in nuclear collisions is characterized by strong coupling, but still admits a quasi-particle description.

Investigating the effect of AMP-activated protein kinase activation on the cardio-renal axis
Creators: name: Wilson, Laura Wilson
Publisher: name: Imperial College London
Year: 2019

description: AMP-activated protein kinase (AMPK) is widely regarded as a master regulator of energy homeostasis, functioning to maintain energy levels under conditions of metabolic stress. Activation of AMPK has emerged as an attractive therapeutic strategy for treatment of many diseases including metabolic, cardiovascular (CV) and renal pathologies. Consistent with this novel, direct AMPK activators have recently been developed that provide evidence for the amelioration of metabolic diseases in vivo. Despite numerous studies demonstrating beneficial effects of AMPK activation, there are also concerns as to the negative impact AMPK activation could have on physiology. Activating mutations in AMPKγ2 (one of three potential AMPKγ subunits that can be incorporated into the enzymatic complex) are known to cause the inherited cardiac disease Wolff-Parkinson White (WPW) syndrome, which is characterised by cardiac hypertrophy, glycogen accumulation and electrical conductance defects. Furthermore, a recent transgenic mouse model of AMPKγ2 activation indicated that AMPK activation could lead to the development of a polycystic kidney (PKD) phenotype in some circumstances. However, the effect of AMPKγ1 activation on cardio-renal physiology is currently largely unknown. To address this question, a novel transgenic mouse model of AMPKγ1 activation was generated by expressing a gain-of-function D316A mutation in the AMPKγ1 subunit, resulting in a constitutively active AMPK complex. The model was generated using the Cre-LoxP system to enable tissue-specific AMPKγ1 activation. Initial observations in a global AMPKγ1 activation model revealed a striking PKD phenotype and an enlarged heart phenotype. Subsequent characterisation of the heart phenotype demonstrated increased cardiac hypertrophy and glycogen accumulation with no electrical conductance defects. The hearts also showed signs of pathological cardiac hypertrophy, and it was established that global AMPKγ1 activation mice had elevated blood pressure. The PKD phenotype and elevated blood pressure were also observed in a kidney-specific model of AMPKγ1 activation, implicating a role for renal AMPKγ1 activation in negatively impacting CV function. Characterisation of the kidney phenotype showed the global AMPKγ1 activation model presented with polyuria, altered electrolyte homeostasis and impaired renal function. Renal cysts appeared to form exclusively in the collecting ducts, and kidneys harvested from gain-of-function AMPKγ1 mice featured increased cAMP accumulation, activation of the MAPK pathway, altered expression of lysosomal-associated proteins and glycogen accumulation. Overall, this work highlights a potential role for AMPK activation in the pathogenesis of renal cyst formation, which may negatively impact the cardio-renal axis.

description: We study the relaxation of a single colloidal sphere which is periodically driven between two nonequilibrium steady states. Experimentally, this is achieved by driving the particle along a toroidal trap imposed by scanned optical tweezers. We find that the relaxation time after which the probability distributions have been relaxed is identical to that obtained by a steady state measurement. In quantitative agreement with theoretical calculations the relaxation time strongly increases when driving the system further away from thermal equilibrium.
title: A Program for Hospitalized Children
Creators: name: Bishop, Leslie Joan
Publisher: name: Utah State University
Year: 1966

description: When children are hospitalized they are exposed to an unfamiliar and frequently forboding world of an efficiently run institution. They cannot, as adults do, afford to interrupt (Plant, 1962) their normal way of living and exclude the relationships, play and learning that contribute to their overall growth.
There is a general tendency for children to be treated much in the same manner that adults are when they are confined in a hospital situation.

He is an adult with adults serving him and he is aware of his power to leave or to dismiss individuals in his attendance.

description: We revisit the flip-flop instability of two-dimensional planar accretion using high-fidelity numerical simulations. By starting from an initially steady-state axisymmetric solution, we are able to follow the growth of this overstability from small amplitudes. In the small-amplitude limit, before any transient accretion disk is formed, the oscillation period of the accretion shock is comparable to the Keplerian period at the Hoyle-Lyttleton accretion radius (R_a), independent of the size of the accreting object. The growth rate of the overstability increases dramatically with decreasing size of the accretor, but is relatively insensitive to the upstream Mach number of the flow. We confirm that the flip-flop does not require any gradient in the upstream flow. Indeed, a small density gradient as used in the discovery simulations has virtually no influence on the growth rate of the overstability. The ratio of specific heats does influence the overstability, with smaller gamma leading to faster growth of the instability. For a relatively large accretor (a radius of 0.037R_a) planar accretion is unstable for gamma = 4/3, but stable for gamma > 1.6. Planar accretion is unstable even for gamma = 5/3 provided the accretor has a radius of < 0.0025R_a. We also confirm that when the accretor is sufficiently small, the secular evolution is described by sudden jumps between states with counter-rotating quasi-Keplerian accretion disks.
title: Wie unterscheiden sich die Lernstrategien beim Erlernen von L2 und L3? Ergebnisse einer empirischen Studie bei taiwanischen Deutsch-als-L3-Lernenden

description: Im mehrsprachigen Taiwan wird Deutsch als Fremdsprache in der Regel als Tertiärsprache nach rund acht Jahren Englischunterricht gelehrt und gelernt. In der Diskussion zum Erwerb einer Tertiärsprache wird davon ausgegangen, dass die Lernenden bereits über Kenntnisse beim Erwerb einer Fremdsprache verfügen und diese dann auch produktiv in den Erwerb der weiteren Fremdsprache einbringen. Mithilfe des von Rebecca Oxford erstellten Fragebogens zu Lernstrategien im Fremdsprachenunterricht (SILL) sollen die Lernstrategien bei Deutsch-als-L3-Lernenden festgestellt und mit den Ergebnissen anderer Studien verglichen werden. Ziel dieser Untersuchung ist es festzustellen, ob sich die Lernstrategien, die Lernende beim Erlernen der Tertiärsprache Deutsch anwenden, von denen unterscheiden, die Lernende im Laufe des Englischunterrichts erworben und angewendet haben. Weiterhin soll untersucht werden, ob die verwendeten Lernstrategien generell beim Fremdsprachenlernen nicht doch eher kulturell geprägt sind. Erfahrungsberichte verschiedener Lehrender legen die Vermutung nahe, dass das unterrichtlich gesteuerte Lernen der Fremdsprache Deutsch mehr durch traditionelle taiwanische Lerntraditionen als durch im Englischunterricht erworbene Lernstrategien geprägt ist.
title: Afrikabezogene Bildungsprogramme und Förderung des Deutschunterrichts und der Germanistik im frankophonen subsaharischen Afrika: Bilanz und Perspektiven der auswärtigen Kultur- und Bildungspolitik Deutschlands am Beispiel Kameruns

description: Die deutsche auswärtige Kulturpolitik in Afrika ist vor allem eine Sprach-, Kultur- und Bildungspolitik gewesen. Wenn diese „dritte Säule“ der deutschen Außenpolitik in den Anfängen im frankophonen subsaharischen Afrika trotz ihrer Einseitigkeit relativ Erfolg erzielt hat, soll sie in dem heutigen Kontext der Globalisierung stärker die Bemühungen der Partnerländer begleiten und ihre Erwartungen berücksichtigen. Am Beispiel Kameruns im Allgemeinen und der Abteilung für angewandte Fremdsprachen an der Universität Dschang in Westkamerun im Besonderen beschreibt der Beitrag die Situation der deutschen Sprache und des Deutschstudiums in Kamerun und zeigt anschließend Perspektiven für die Zukunft.

description: We present a photometric study of the neglected open cluster Berkeley 53. We derived its fundamental parameters, such as the age, the interstellar reddening, and the distance from the Sun, based on BV photometry combined with near-infrared JHK data. The structure and the mass function of the cluster were also studied and the total number of members and the total mass were estimated. The cluster was found to be a rich and massive stellar system, located in the Perseus Arm of the Milky Way, 3.1+/-0.1 kpc from the Sun. Its age exceeds 1 Gy but it seems to be very young in the context of its dynamical evolution. The analysis of the two-color diagrams and color-magnitude diagrams indicates that the cluster is significantly reddened. However, both methods resulted in different values of E(B-V), i.e. 1.21+/-0.04 and 1.52+/-0.01, respectively. This discrepancy suggests the presence of an abnormal interstellar extinction law toward the cluster.

description: Selbstlernzentren gehören zu den Standardeinrichtungen vieler Sprachlerninstitutionen weltweit, die damit oft unterschiedliche Ziele verfolgen. Einige dieser Einrichtungen sind als Ergänzung des formellen Klassenunterrichts konzipiert, während andere gar als Ersatz dafür fungieren. Im Zuge der Fortschritte in der Informations- und Kommunikationstechnologie entwickelt sich das Internet zunehmend zu einem beinahe unverzichtbaren Bestandteil unseres täglichen und beruflichen Lebens. Das Internet gewinnt durch seine Verbreitung und seine gesteigerten Multimedia-Möglichkeiten immer mehr an Bedeutung für das Fremdsprachenlernen, wie Sturtridge konstatiert: "The electronic revolution makes the delivery of teaching possible either in the learner's home or his place of work, and it is feasible that self-access centres will become more providers of distant learning than library-like places to go to study." (1997, S. 67) Das Projekt "e-daf" stellt einen Versuch der National University of Singapore (kurz: NUS) dar, das Potential des Internets für die Bereitstellung eines Selbstlernangebots zu nutzen. Im vorliegenden Aufsatz werden zunächst lernkontextuelle Entwicklungen auf der nationalen sowie der universitären Ebene knapp umrissen, welche die Initiierung und Durchführung dieses Projekts bedingen. Der nachfolgende Theorieteil bietet einen Überblick über Forschungserkenntnisse, die der Gestaltung des Projekts zugrunde liegen. Der nächste Abschnitt befasst sich mit der Konzeption und Realisation des Projekts und bietet einen Einblick in das in "e-daf" enthaltene Lernangebot. Nach einer kurzen Erörterung des Beitrags, den diese technologiegestützte Innovation zur Förderung des autonomen Lernens leisten kann, werden abschließend Zukunftsperspektiven für Selbstlernzentren besprochen, die sich durch eine elektronische Lernplattform wie "e-daf" ergeben.

description: We report the discovery of a low-density exoplanet transiting an 11th magnitude star in the Southern hemisphere. WASP-15b, which orbits its host star with a period P=3.7520656+-0.0000028d has a mass M_p=0.542+-0.050M_J and radius R_p=1.428+-0.077R_J, and is therefore the one of least dense transiting exoplanets so far discovered (rho_p=0.247+-0.035g cm^-3). An analysis of the spectrum of the host star shows it to be of spectral type around F5, with an effective temperature T_eff=6300+-100K and [Fe/H]=-0.17+-0.11.

Applications of endogenous information acquisition by institutional investors
Creators: name: Zhang, Jingyu
Publisher: name: Imperial College London

description: Acquiring information consumes investors' learning capacity, a valuable and limited resource that requires optimal allocation. Chapter One theoretically explores and empirically examines the roles of macroeconomic announcements when investors digest firm-earnings news. Macroeconomic announcements can distract investors upon being released if information about the aggregate risk competes with firm-earnings news to occupy investors' learning capacity. However, valuable information about the aggregate risk is disclosed to the general public via these announcements, temporarily lifting the burdens on investors to privately acquire such information and therefore leaving them more learning capacity to process firm-specific information. Combining these competing views, this chapter incorporates the releases of macroeconomic announcements into a rational inattention framework, and proposes the "attention re-allocation mechanism" to understand their effects on informational efficiency of individual firms. This mechanism confirms the distracting effects of macroeconomic announcements prior to being released and their complementary effects upon being released. This framework further predicts that these effects are more (less) pronounced during expansions (recessions). Empirical evidence is provided to support model predictions. Chapter Two revisits information acquisition theory from a corporate governance perspective. In this chapter, I provide a rational expectations framework to model monitoring and information acquisition and explore their within- firm and cross- firm interactions. My model proposes the "monitoring-for-learning" mechanism to describe that investors optimally re-allocate monitoring effort from firms with low value of information acquisition to firms with high value of information acquisition. This mechanism has empirical implications for information acquisition: Institutional investors tend to acquire more precise information about the firms they can more effectively engage with and about those they have larger holdings in. Chapter Three provides empirical evidence to support model predictions in Chapter Two.
