Chinesische Gratwanderung

description: China wird gelegentlich von westlichen Politikern als Hort der Stabilität inmitten der asiatischen Turbulenzen charakterisiert. Dieses Bild verzerrt jedoch die Wirklichkeit: Chinas Wirtschaft ist von der asiatischen Finanz- und Wirtschaftskrise zwar nicht unmittelbar und mit voller Wucht getroffen worden. China profitierte zunächst von der weitgehenden Geschlossenheit seiner Devisen- und Wertpapiermärkte, und man könnte in diesem Zusammenhang von der „Gnade der späten Liberalisierung” sprechen: Die Aufrechterhaltung strikter Kapitalverkehrskontrollen erwies sich während der ersten Attacken der „Asienkrise” für China als Vorteil.

description: Obwohl der chinesische Begriff für „Asienkrise” auf den Finanzaspekt {Dongya jin’e weiji, wörtl.: „asiatische Geldmengenkrise”) eingeschränkt ist, wird die Gesamtproblematik doch keineswegs spezifisch wirtschaftlich, sondern generell politisch interpretiert. Nur konsequent ist es deshalb, wenn auch die chinesische Außenpolitik dem Thema Rechnung trägt und immer wieder betont, daß China die Herausforderung nicht nur mit Wirtschaftsreformen, sondern auch mit einer Politik besonderer Rücksichtnahme auf nachbarliche Interessen zu beantworten habe.

description: Semiconductor nanolasers are potentially important for many applications. Their design and fabrication are still in the early stage of research and face many challenges. In this paper, we demonstrate a generally applicable membrane transfer method to release and transfer a strain-balanced InGaAs quantum-well nanomembrane of 260 nm in thickness onto various substrates with a high yield. As an initial device demonstration, nano-ring lasers of 1.5 μm in outer diameter and 500 nm in radial thickness are fabricated on MgF2 substrates. Room temperature single mode operation is achieved under optical pumping with a cavity volume of only 0.43λ03 (λ0 in vacuum). Our nano-membrane based approach represents an advantageous alternative to other design and fabrication approaches and could lead to integration of nanolasers on silicon substrates or with metallic cavity.

description: The application of distributed networks such as the hybrid cloud, IoT structure, and the 5G system shows that conventional routing protocols cannot handle dynamic systems and unpredictable calls. This paper presents the ERF, a novel concept intended as a shift from conventional approaches used in narrow domains such as Elasticity. It may react instantly to choose the most effective way to accomplish a given objective by scaling or changing course. ERF leverages sophisticated artificial intelligence algorithms and real-time traffic information to optimize path choices and their reliability. Its methodologies are designed to integrate with existing systems and make network conditions ahead of schedule while generally suggesting latency, throughput, and reliability enhancements. Empirical results prove that ERF is effective in overcoming the problems of RTT-based routing for current referential distributed networks. Whereas these inventions provide the basis for future developments in improving networks, they are particularly valuable to administrators, service providers, and end-users in dynamic networks.

description: Die politische Verstimmung zwischen Bonn und Beijing im Sommer 1996, die mit der Verabschiedung der „Tibet-Resolution“ durch den Deutschen Bundestag ihren Höhepunkt erreichte, hat die bilateralen Beziehungen nicht anhaltend belastet. Zwar war im Juni 1996 der Besuch von Außenminister Kinkel durch die chinesische Seite abgesagt worden, jedoch wurde die Chinareise des deutschen Außenministers bereits im Oktober 1996 nachgeholt und die politischen Konsultationen wieder aufgenommen. Die deutsche Wirtschaft zeigt bei den Direktinvestitionen ein anhaltend starkes Engagement. Im bilateralen Außenhandel ist das Bild zweigeteilt: Bei den Exporten war 1996 nur ein moderater Anstieg zu verzeichnen, die deutschen Importe dagegen erreichten 1996 ein höheres Wachstum als im vorangegangenen Jahr. Im folgenden Beitrag soll der Stand der deutsch-chinesischen Wirtschaftsbeziehungen Mitte der neunziger Jahre dargestellt werden. Zunächst wird die Entwicklung des bilateralen Außenhandels und die Struktur der deutschen Exporte nach China sowie der deutschen Importe aus China aufgezeigt. Anschließend werden die deutschen Direktinvestitionen in China betrachtet. Dabei wird die Entwicklung der letzten Jahre dargestellt und ein Überblick über Programme zur Förderung der deutschen Investitionen gegeben. Anschließend wird auf die aktuelle Situation der deutschen Entwicklungszusammenarbeit mit der VR China eingegangen. Der Beitrag schließt mit einem Ausblick auf die weitere Entwicklung der deutsch-chinesischen Wirtschaftsbeziehungen.

description: Die politische Landschaft Taiwans wurde in letzter Zeit durch eine Reihe von Ereignissen erdbebenartig erschüttert. Die Ära Li Denghuis (Lee Teng-hui, 74), Staatspräsident und Parteivorsitzender der Regierungspartei KMT (Kuomintang), nähert sich dem Ende. Neue Machtkämpfe der sogenannten „mittleren Generation“ (zhongshengdai) um seine Nachfolge sind so gut wie programmiert oder haben bereits begonnen. Li, ursprünglich Professor für Landwirtschaft an der Universität Taiwan, galt früher als ein farbloser Politiker. Von 1984-1988 war er ein sehr unauffälliger Vizepräsident unter Jiang Jingguo (Chiang Ching-kuo), übernahm aber nach dessen Tod im Januar 1988 das Präsidialamt. Nachdem er noch im selben Monat auch zum Parteivorsitzenden der KMT gewählt worden war, begann er eine „Säuberungswelle“. Mit der geschickten Taktik yuqu guyu (erst geben, um dann zu nehmen), d.h. zuerst Beförderung und dann Entlassung des potentiellen Gegners, hat er alle einflußreichen Vertrauten seines Vorgängers in Regierung, Partei und Armee entmachtet. Darüber hinaus baute er per Liberalisierung und Demokratisierung in der Innenpolitik sowie durch außenpolitische Offensiven sein Charisma auf.

description: Three academic years have been considered for the evaluation of the impact of an online tutoring course of general and inorganic chemistry for freshmen students of the University of XX (Italy). The online material mainly consists of video tutorials, other open source web tools and multi-choice self-assessment exercises. During the academic year 2016-2017, the e-learning course was not available yet, but then the online course was first implemented (2017/18) and fully adopted (2018/2019).The online tutoring support was activated alongside a traditional general chemistry course, adopting a blended mode, with the aims of: (i) homogenising freshmen’s chemistry knowledge (ii) fostering the most appropriate method of study in a multi access modality (iii) implementing the Johnstone’s three levels’ knowledge and (iv) increasing students’ self-confidence, by the means of a self-evaluation training process. Differently from previous studies, the online course herein aimed mainly to develop a correct method of study of chemistry topics, with a punctual description of what-and-how to do. The results, i.e. the exam's scores, the time spent in the platform, and the successful percentage of students per year, have been collected and analysed through qualitative and quantitative methods. Apart a general satisfaction of the students perceived by the answers to a survey questionnaire, the analysis of the data shows an increase of 11 % of students passing the final exam within three exam sessions together with an improvement and a positive correlation between the time spent on the platform and the mid-term scores achieved.

Bayesian inverse problems

description: Reservoir simulation is critically important for optimally managing petroleum reservoirs. Often, many of the parameters of the model are unknown and cannot be measured directly. These parameters must then be inferred from production data at the wells. This is an inverse problem which can be formulated within a Bayesian framework to integrate prior knowledge with observational data. Markov Chain Monte Carlo (MCMC) methods are commonly used to solve Bayesian inverse problems by generating a set of samples which can be used to characterize the posterior distribution. In this work, we present a novel MCMC algorithm which uses a sequential transition kernel designed to exploit the redundancy which is often present in time series data from reservoirs. This method can be used to efficiently generate samples from the Bayesian posterior for time-dependent models. While this method is general and could be useful for many different models, we focus here on reservoir models with faults. A fault is a heterogeneity characterized by a sharp change in the permeability of the reservoir over a region with very small width relative to its length and the overall size of the reservoir domain [1]. It is often convenient to model faults as lower dimensional surfaces which act as barriers to the flow. The transmissibility multiplier is a parameter which characterizes the extent to which fluid can flow across a fault. We consider a Bayesian inverse problem in which we wish to infer fault transmissibilities from measurements of pressure at wells using a two-phase flow model. We demonstrate how the sequential MCMC algorithm presented here can be more efficient than a standard Metropolis-Hastings MCMC approach for this inverse problem. We use integrated autocorrelation times along with mean-squared jump distances to determine the performance of each method for the inverse problem

description: Zur Jahresmitte 1997 entwickelte Nordkorea sich in der chinesischen Außenpolitik wieder einmal zu einem Hauptthema - eine Entwicklung, die von der Beijinger Führung nicht gerade mit Behagen zur Kenntnis genommen wird, obwohl sie sich nach außen hin alle Mühe gibt, freundliche Miene zu zeigen und jene Rituale fortzusetzen, die sich zwischen Pyongyang und Beijing nun einmal seit Jahrzehnten eingespielt haben: Da waren erstens die 36. Gedenkfeiern zu dem am 11.7.1961 zwischen beiden Ländern abgeschlossenen „Vertrag über Freundschaft, Zusammenarbeit und gegenseitigen Beistand“. Zweitens fanden am 8. Juli die Gedenkfeierlichkeiten anläßlich des dritten Todestags von Kim II Sung statt, an denen diesmal in Beijing kein Geringerer als die Nr.3 in der chinesischen Führung, Qiao Shi, teilnahm. Drittens tauchte ein weiterer „Gedenktag“ auf, der zwischen beiden Seiten allerdings nicht offen angesprochen wurde, weil er zu peinlich ist, nämlich die Aufnahme diplomatischer Beziehungen zwischen Beijing und Seoul am 24.8.1992. Viertens galt es, wenn auch äußerst taktvoll, die Hungersnot in Nordkorea zu thematisieren, die bis Anfang August offensichtlich schon Zehntausende von Menschen, vor allem Kinder, in Nordkorea dahingerafft hatte und von der sich das durch jahrzehntelange Mißwirtschaft und zusätzlich auch noch durch eine Trockenheitskatastrophe hernuntergewirtschaftete Land offensichtlich auf lange Zeit nicht erholen dürfte. Trotz aller gegenseitigen Spannungen muß Nordkorea doch eingesehen haben, daß die VRCh die einzige noch einigermaßen zuverlässig funktionierende Quelle für Ersatzteile und Lebensmittel geblieben ist. Immer wieder hat die Volksrepublik ja Hilfe geleistet, so z.B. im Oktober 1995. Auch in der Notlage des Jahres 1997 ist die VR China erneut gefragt, wobei sie nicht nur staatliche Hilfe zur Verfügung stellt, sondern auch ihre Privathändler frei gewähren läßt, die durchaus auf Gewinnbasis arbeiten und mit der nordkoreanischen Not einträgliche Geschäfte zu machen wissen, indem sie Lebensmittel ins Nachbarland liefern und dafür im Gegenzug Schrott und Heilgräser für medizinische Tinkturen eintauschen, wobei der Schrott z.T. aus demontierten Fabriken, also aus der industriellen Substanz, stammt.

description: In this two part work we prove that for every finitely generated subgroup $Γ< \text{Out}(F_n)$, either $Γ$ is virtually abelian or $H^2_b(Γ;\mathbb{R})$ contains an embedding of $\ell^1$. The method uses actions on hyperbolic spaces, for purposes of constructing quasimorphisms. Here in Part I, after presenting the general theory, we focus on the case of infinite lamination subgroups $Γ$ - those for which the set of all attracting laminations of all elements of $Γ$ is infinite - using actions on free splitting complexes of free groups.

description: This paper develops a virtual reality education system for mobile devices through mobile virtual reality technology with virtual reality glasses. The purpose of this study was to investigate the impact of mobile Virtual interactive e-learning environment on 3D operating system course learning motivation. The paper aims to increase students’ interest and enhance their learning motivation for understanding CPU process scheduling algorithms in an operating systems course. A total of 110 students from the department of computer sciences at Sadat Academy were invited to participate. A 5-point scale was adopted based on the ARCS model to stimulate learning to collect student data. A one-way analysis of variance (ANOVA) was performed to assess if the apparent difference was significant. Perform a data factor analysis to determine the appropriate factor (p = 0.000 < 0.05). The results show that mobile virtual reality game-based learning is an effective pedagogical tool for operating systems education, and it can promote students’ motivation and interest in learning 3D animation.

description: Numerical simulations were used to study signal formation in a Thick Gaseous Electron Multiplier (THGEM) and in THGEM -based Thick-WELL (THWELL) and Resistive-Plate WELL (RPWELL) detectors. The signal shapes were simulated in mixtures of Argon and Neon with $5\%$ Methane under irradiation with soft x-rays and muons. Anode-induced raw signals were convoluted with the response functions of charge-sensitive and current-sensitive pre-amplifiers. The simulation toolkit was validated by the good agreement reached between the simulated and measured response, with different pre-amplifiers. It indicates that our simulations framework provides valid insight into the inherent complex dynamical processes of the various detectors.

description: In the online learning environment, learners play an important role in attaining successful learning. Considering the students’ self-directed learning is important to university because of online learning is done in unlimited space and time. Through online mode, the learners do the social interaction. The interaction in online learning is categorized into four dimensions namely the interaction between the teachers and students, students and students, teachers and topic, and students and topic. This study emphasized the relationship between self-directed learning and students’ social interaction in the online learning environment. Statistical associations between variables were inspected with parametric correlation and statistically significant differences between independent samples were examined with a one-way analysis of variance. This study showed a significant relationship between stu-dents’ self-directed learning readiness (SDLR) and their social interaction, and there were different social interac-tions between students based on their SDLR levels.

description: The teachers in higher education (HE) could take a better advantage of the existing vast numbers open educational resources (OER) as well as invite their students in the process of sharing and knowledge co-creation, if they started using and adapting existing OER and/or creating their own OER. The question of this research was whether involving teachers into OER creation and providing them with a tool of a collaborative platform would increase their openness and readiness to share and become open educators? The research was performed on design-based research methodology and intervention, offering a group of university teachers in Lithuania to create, adapt and share OER in the format of slides, providing them with a collaborative platform as a tool, facilitating open-licensed content creation and publishing. After the intervention most of the participating university teachers emphasized the importance of openness, the feeling of more responsibility while preparing their open slides, expressed better understanding of OER, and even changed their pedagogy. Besides, OER integration had a direct impact upon student awareness on OER, overcoming the barriers towards openness, and their ability to contribute to the course.

description: During the past few decades, it seems that personalizing and adjusting the e-courses’ content based on individual learning styles is rather important. Indeed, several studies have been carried out throughout the years regarding the a priori personalization and adjustment of e-courses systems. This way modern LMSs (Learning Management Systems) could identify beforehand the learning styles of the e-course attendants and adjust the lesson content flow and type based on personal learning styles. Nevertheless, little bibliography exists on how to assess the compatibility level between educational content and learning styles dimensions of an LMS, in a real-life environment. With the above thoughts in mind, the current work attempts to introduce and verify an innovative framework for the students' learning styles and e-courses compatibility assessment, based on the content type and volume. The proposed framework is validated through its application at an LMS in a real-life academic environment. Such an approach could be very beneficial for already deployed e-courses on LMSs that aim to differentiate educational content provision based on users’ profiles.

description: Digital challenges tied to the multifaceted landscape of citizenship are the focus of a workshop developed within an instructional technology course that took place in the academic year 2019-2020 in the degree course in Education Science (curriculum socio-pedagogical professional educator) at University of Macerata (Italy). The experience is framed in a multiple-case study where the case here described is intended as the last unit of analysis. The aim of the qualitative study is to check how a hands-on workshop on digital citizenship, which involved students in a participatory video project, affected their reflection about (1) the theme and the effectiveness of media formats used for the educational design and communication; (2) the collaborative attitudes that were involved for the creation of a video artefact designed as an educational resource. The data were collected through different tools (reflection papers, questionnaires and interviews) and were coded with a content analysis approach to be, then, triangulated with the artefacts created by the 31 students of the sample who worked in small groups.

description: As a result of the rapid development in educational technology, the design of instructional aids has been gaining a lot of significance. To date, researchers have studied the effect of using instructional aids on the learners’ academic performance, and a positive effect has often been proven. This study reviews and analyses existing literature and empirical evidence in relation to color use in designing instructional aids. Two major areas reviewed in the study are the Color Theory and the psychological and physiological impacts of color on learners. The results show that using colors in designing instructional aids plays an important role in enabling learners to concretize concepts and relations. Results also indicate that the effects of using color reflect on both the learners’ and the teachers’ emotional experiences. The results of the study may benefit educators, teachers, and pre-service teachers in designing the right and favourable learning environments for their teaching strategies.

description: Given a group acting on a Gromov hyperbolic space, Bestvina and Fujiwara introduced the WPD property --- weak proper discontinuity --- for studying the 2nd bounded cohomology of the group. We carry out a more general study of second bounded cohomology using a 'really' weak property discontinuity property known as WWPD that was introduced by Bestvina, Bromberg, and Fujiwara.

description: It is suggested that the "B" in QBism rightfully stands for Bohr. The paper begins by explaining why Bohr seems obscure to most physicists. Having identified the contextuality of physical quantities as Bohr's essential contribution to Kant's theory of science, it outlines the latter, its proper contextuality (human experience), and its decontextualization. In order to preserve the decontextualization achieved by Kant's theory, Bohr seized on quantum phenomena as the principal referents of atomic physics, all the while keeping the universal context of human experience at the center of his philosophy. QBism, through its emphasis on the individual experiencing subject, brings home the intersubjective constitution of objectivity more forcefully than Bohr ever did. If measurements are irreversible and outcomes definite, it is because the experiences of each subject are irreversible and definite. Bohr's insights, on the other hand, are exceedingly useful in clarifying the QBist position, attenuating its excesses, and enhancing its internal consistency.

description: This paper proposes a framework to assess the stability of an ordinary differential equation which is coupled to a 1D-partial differential equation (PDE). The stability theorem is based on a new result on Integral Quadratic Constraints (IQCs) and expressed in terms of two linear matrix inequalities with a moderate computational burden. The IQCs are not generated using dissipation inequalities involving the whole state of an infinite-dimensional system, but by using projection coefficients of the infinite-dimensional state. This permits to generalize our robustness result to many other PDEs. The proposed methodology is applied to a time-delay system and numerical results comparable to those in the literature are obtained.

description: Die zunehmende Sättigung der Automobilmärkte in den westlichen Industrienationen und das mittelfristig beträchtliche Marktpotential im asiatisch -pazifischen Raum hat zu einer Verschiebung der globalen Automobilproduktion geführt. Vor allem die VR China ist mittel- bis langfristig als Absatzmarkt sowohl für Pkw als auch für kommerzielle Fahrzeuge interessant,1 da sie eine sehr geringe Fahrzeugdichte (neun Fahrzeuge für 1.000 Personen2) mit einem starken Wirtschaftswachstum kombiniert.

description: Spontaneous conversations in real-world settings such as those found in child-centered recordings have been shown to be amongst the most challenging audio files to process. Nevertheless, building speech processing models handling such a wide variety of conditions would be particularly useful for language acquisition studies in which researchers are interested in the quantity and quality of the speech that children hear and produce, as well as for early diagnosis and measuring effects of remediation. In this paper, we present our approach to designing an open-source neural network to classify audio segments into vocalizations produced by the child wearing the recording device, vocalizations produced by other children, adult male speech, and adult female speech. To this end, we gathered diverse child-centered corpora which sums up to a total of 260 hours of recordings and covers 10 languages. Our model can be used as input for downstream tasks such as estimating the number of words produced by adult speakers, or the number of linguistic units produced by children. Our architecture combines SincNet filters with a stack of recurrent layers and outperforms by a large margin the state-of-the-art system, the Language ENvironment Analysis (LENA) that has been used in numerous child language studies.

description: Mit Ausnahme von Japan, das sich bereits Ende des letzten Jahrhunderts zu einem Industriestaat und einer Weltmacht entwickelt hat, galt Ostasien einschließlich Süd- ostasiens bis Ende der 50er und Anfang der 60er Jahre wirtschaftlich noch als eine unterentwickelte Region der Welt, nicht nur weit rückständiger als Europa und Nordamerika, sondern auch als Lateinamerika. Seit den 70er Jahren tauchten die sogenannten asiatischen kleinen „Tiger“ - in der chinesischen Literatur auch „Drachen“ - auf, d.h. die Schwellenländer oder in Englisch „Newly Indu- strializing Economie^ (NIEs), zunächst Hongkong, Taiwan, Südkorea und Singapur, dann Thailand, Malaysia und Indonesien, die allesamt in den letzten Jahrzehnten ein ungewöhnlich hohes Wachstum zu verzeichnen hatten. Vor 35 Jahren hatte die Region nur einen Anteil von 4% an der Gesamtproduktion der Welt, inzwischen ist er auf 24% gestiegen, und bis Ende dieses Jahrhunderts soll er nach allgemeiner Erwartung eine Höhe von einem Drittel der Weltproduktion erreichen.1 Diese Entwicklung wurde von vielen Experten einschließlich der Weltbank und zahlreichen anderen internationalen Wirtschaftsorganisationen als ein Wunder und Modell für die Dritte Welt gepriesen.2 Es entstand der Begriff der „asiatischen Wertd‘, was politische Stabilität unter autoritärer Regierung, fleißige, flexible und kollektive Arbeit, Bildungsbewußtsein, hohe Spar- und Investitionsquote, reglementierte und exportorientierte Wirtschaft usw. bedeutete.

description: Recently, a purely quantum version of polar codes has been proposed in [1] based on a quantum channel combining and splitting procedure, where a randomly chosen two-qubit Clifford unitary acts as channel combining operation. Here, we consider the quantum polar code construction using the same channel combining and splitting procedure as in [1], but with a fixed two-qubit Clifford unitary. For the family of Pauli channels, we show that polarization happens in multi-levels, where synthesized quantum virtual channels tend to become completely noisy, half-noisy, or noiseless. Further, we present a quantum polar code exploiting the multilevel nature of polarization, and provide an efficient decoding for this code. We show that half-noisy channels can be frozen by fixing their inputs in either the amplitude or the phase basis, which allows reducing the number of preshared EPR pairs compared to the construction in [1]. We provide an upper bound on the number of preshared EPR pairs, which is an equality in the case of the quantum erasure channel. To improve the speed of polarization, we propose an alternative construction, which again polarizes in multi-levels, and the previous upper bound on the number of preshared EPR pairs also holds. For a quantum erasure channel, we confirm by numerical analysis that the multilevel polarization happens relatively faster for the alternative construction.

description: „Arbeitsstil4 Zuofeng [1], wörtlich (Arbeits-) „Stil1 oder „Arbeitsweise, ist ein Schlüsselbegriff der sinokommunistischen Politterminologie, mit dem die grundlegende Eigenart politischen Führungsverhaltens beschrieben werden soll. Man versteht unter zuofeng die innere Einstellung, mit der ein Funktionär an die Lösung seiner Aufgaben herangeht. Politische „Linid‘ und „Stil“ verhalten sich zueinander wie Inhalt und Form, die untrennbar miteinander verwoben sind. Auch hier gibt es eine konfuzianische Reminiszenz zur Ausgewogenheit zwischen innen und außen: Übertrifft der Inhalt die Form, so erscheint der Mensch ungehobelt, übertrifft aber die Form den Inhalt, so entsteht der Eindruck von „Glattheit1. Nur dort, wo beides sich „harmonisch ergänzt1, entsteht Vorbildhaftigkeit und Vertrauen.

description: The major challenge in the digital era is the management of big data. A substantial share of digitization is taken from the e-learning. In this respect, the current article deals with generation of questions for testing the acquired levels of students’ knowledge. For this purpose, an algorithm for generation of questions for tests with different level of complexity is proposed. The main stage of this algorithm is using of mathematical combinatorial optimization model. Using this model makes it possible to formulate different tasks, whose solutions determine a subset of questions that correspond to different degree of test complexity. Essential part of this model is the use of binary integer variables to determine whether a question will be a part of the test or not. The advantage of the proposed approach is the flexibility to decrease or increase the number of questions used to compose the test preserving the required score in accordance to the particular level of test complexity. The conducted investigations over a year show, that the effect of testing can improve retention of knowledge and lead to improved end results. The applicability of the proposed algorithm along with the formulated mathematical model is demonstrated in a case study on the excerpt of questions from the web programming course. The proposed algorithm could be used for generation of tests with different degree of complexity for other learning contents.

description: We develop a medium-size semi-structural time series model of inflation dynamics that is consistent with the view - often expressed by central banks - that three components are important: a trend anchored by long-run expectations, a Phillips curve and temporary fluctuations in energy prices. We find that a stable long-term inflation trend and a well identified steep Phillips curve are consistent with the data, but they imply potential output declining since the new millennium and energy prices affecting headline inflation not only via the Phillips curve but also via an independent expectational channel. A high-frequency energy price cycle can be related to global factors affecting the commodity market, and often overpowers the Phillips curve thereby explaining the inflation puzzles of the last ten years.

description: This paper presents a model of a system capable of addressing the training needs identified for small universities, using the University of Trás-os-Montes e Alto Douro (UTAD) as a case study. In addition to supporting the typical needs of distance learning/education (e.g., e-learning), it is also intended that the proposed system complements the traditional classroom-based teaching. This model will have two modules: the physical/infrastructural module and the policies/practices module. While the physical module will have all the infrastructure services associated with educational practices, such as the e-learning platform, the policy module will include institutional policies and rules in the creation, development, practice and management of courses, equipment and physical spaces, such as exam rooms. In line with these, UTAD has come to recognize that e-learning should be part of its strategy for its training offer and, consequently, is being adopting new policies, namely through the signing of protocols with other institutions with more experience using e-learning. As such, a review of other models and systems that have been successfully implemented in other international reference universities will also be briefly presented here. The courses implemented so far, and the results achieved, are also presented and commented.
