text: Vernetztes Wissen ist ein zentrales Lernziel des Hochschulstudiums, insbesondere
im interdisziplinär angelegten Studienfach Komparatistik. Um den Aufbau vernetzten
Wissens bei Bachelorstudierenden der Komparatistik zu unterstützen, ist in diesem
Projekt Portfolioarbeit eingesetzt worden, die als Methode selbsttätigen und selbstreflexiven
Lernens geeignet erscheint, zur Auseinandersetzung mit Lerninhalten zu motivieren
und zur Kompetenzentwicklung der Studierenden beizutragen. Mittels unstrukturierter
Beobachtungen der Portfolioarbeit im Seminar sind inhaltliche Effekte und methodische
Entwicklungen erfasst worden. Anhand anteilig quantitativer, überwiegend qualitativer
Inhaltsanalysen der Portfolios sind konkrete Vernetzungen zwischen Lerninhalten
ermittelt worden. Die Explorationsstudie zeigt veränderte Perspektiven und geweckte
Interessen bei den Studierenden durch die Portfolioarbeit sowie vielfältige Kontextualisierungen,
Vergleiche und Verknüpfungen in den Portfolios auf und bietet hierdurch einen
möglichen Ansatzpunkt für strukturelle Empfehlungen für das Studienfach Komparatistik.

text: Knowledge networks are a central learning objective in higher education, especially
in the inherently interdisciplinary discipline of comparative literary and cultural
studies. To support the development of knowledge networks with undergraduate students
of comparative literary and cultural studies, this project utilized portfolio
work as a method of self-actuating and self-reflective learning suitable for motivating
examinations of learning contents and contributing to students’ skill development.
Using naturalistic observations of the portfolio work within the seminar, effects
and developments were recorded. With partly quantitative, predominantly qualitative
content analyses of the portfolios, concrete connections between learning contents
were determined. The explorative study shows changed perspectives and peaked interests
of the students because of portfolio work as well as diverse contextualisations,
comparisons and connections in the portfolios, thus offering a possible starting
point for structural recommendations for the discipline of comparative literary
and cultural studies.

text: 'In 1921, John Wisdom (1904–1993) became a member of Fitzwilliam House, Cambridge,
where he read philosophy and attended lectures by G. E. Moore, C. D. Broad, and
J. E. McTaggart. He received his BA in 1924, after which he worked for five years
at the National Institute of Industrial Psychology. From 1929 to 1934, Wisdom
was a Lecturer in the department of logic and metaphysics at the University of
St Andrews and a colleague of G. F. Stout. After the publication of his book Interpretation
and Analysis (1931) and five articles on “Logical Constructions” in Mind (1931–3),
Wisdom became a Lecturer in Moral Sciences in Cambridge and a Fellow of Trinity
College. This gave him the opportunity to gain first-hand knowledge of Wittgenstein’s
philosophy. Since nothing by Wittgenstein but Tractatus appeared in print for
decades, Wisdom’s publications of these years were—mistakenly—read as portents
of the new ideas of Wittgenstein himself. The publication of Wittgenstein’s Philosophical
Investigations in 1953 brought with it, among other things, the fall of Wisdom’s
popularity. '

text: Susan Stebbing wrote only once on Wittgenstein, in her paper ‘Logical Positivism
and Analysis’ (1933). The paper was unusually critical of Wittgenstein. It put
the Cambridge analytic philosophy of Moore and Russell in a sharp opposition to
the positivist philosophy of the Vienna Circle, in which Stebbing included Wittgenstein.
Whereas the positivists were interested in analysing language, the Cambridge realists
were analysing facts. To be more explicit, the analytic philosophers were engaged
in directional analysis, which seeks to illuminate (to elucidate) the multiplicity
of the analysed facts. In contrast, positivists aimed at a final analysis that
proves that there are simples. Stebbing’s sympathies were clearly on the side
of the Cambridge realists. The important implication of Stebbing’s paper was that
it urged Wittgenstein to change the style of his philosophy, abandoning those
points which allegedly connected him with the Vienna Circle.

text: "The aim of this study was to find out whether teaching how to search for
literature\r\nwould be more beneficial to students and teachers if done online
through short videos\r\nrather than in person during course time. To find out
whether online videos are more\r\nbeneficial, two courses were asked to fill in
questionnaires, one at the beginning and\r\none at the end of the semester. One
of the courses received the input online via videos\r\nand were given an exercise
to put the newly learned skills to use, the other course\r\nserved as a control
group and learned how to search for literature during the course.\r\nThe results
show that while the difference between the two groups is not significant,\r\nthe
videos can still be regarded as being more beneficial than teaching the necessary\r\nskills
during course time."

text: Employing main and sector-specific investment-grade CDS indices from the North
American and European CDS market and performing mean-variance out-of-sample analyses
for conservative and aggressive investors over the period from 2006 to 2014, this
paper analyzes portfolio benefits of adding corporate CDS indices to a traditional
financial portfolio consisting of stock and sovereign bond indices. As a baseline
result, we initially find an increase in portfolio (downside) risk-diversification
when adding CDS indices, which is observed irrespective of both CDS markets, investor-types
and different sub-periods, including the global financial crisis and European
sovereign debt crisis. In addition, the analysis reveals higher portfolio excess
returns and performance in CDS index portfolios, however, these effects clearly
differ between markets, investor-types and sub-periods. Overall, portfolio benefits
of adding CDS indices mainly result from the fact that institutional investors
replace sovereign bond indices rather than stock indices by CDS indices due to
better risk-return characteristics. Our baseline findings remain robust under
a variety of robustness checks. Results from sensitivity analyses provide further
important implications for institutional investors with a strategic focus on a
long-term conservative portfolio management.

text: Multi-attribute value theory (MAVT)-based recommender systems have been proposed
for dealing with issues of existing recommender systems, such as the cold-start
problem and changing preferences. However, as we argue in this paper, existing
MAVT-based methods for measuring attribute importance weights do not fit the shopping
tasks for which recommender systems are typically used. These methods assume well-trained
decision makers who are willing to invest time and cognitive effort, and who are
familiar with the attributes describing the available alternatives and the ranges
of these attribute levels. Yet, recommender systems are most often used by consumers
who are usually not familiar with the available attributes and ranges and who
wish to save time and effort. Against this background, we develop a new method,
based on a product configuration process, which is tailored to the characteristics
of these particular decision makers. We empirically compare our method to SWING,
ranking-based conjoint analysis and TRADEOFF in a between-subjects laboratory
experiment with 153 participants. Results indicate that our proposed method performs
better than TRADEOFF and CONJOINT and at least as well as SWING in terms of recommendation
accuracy, better than SWING and TRADEOFF and at least as well as CONJOINT in terms
of cognitive load, and that participants were faster with our method than with
any other method. We conclude that our method is a promising option to help support
consumers' decision processes in e-commerce shopping tasks.

text: 'Advancements in information technology have changed the way customers experience
a service encounter and their relationship with service providers. Especially
technology-based self-service channels have found their way into the 21st century
service economy. While research embraces these channels for their cost-efficiency,
it has not examined whether a shift from personal to self-service affects customer–firm
relationships. Drawing from the service-dominant logic and its central concept
of value-in-context, we discuss customers’ value creation in self-service and
personal service channels and examine the long-term impact of these channels on
customer retention. Using longitudinal customer data, we investigate how the ratio
of self-service versus personal service use influences customer defection over
time. Our findings suggest that the ratio of self-service to personal service
used affects customer defection in a U-shaped manner, with intermediate levels
of both self-service and personal service use being associated with the lowest
likelihood of defection. We also find that this effect mitigates over time. We
conclude that firms should not shift customers toward self-service channels completely,
especially not at the beginning of a relationship. Our study underlines the importance
of understanding when and how self-service technologies create valuable customer
experiences and stresses the notion of actively managing customers’ cocreation
of value. '

text: 'Die Auseinandersetzung mit Bildungstechnologien erfolgt häufig ausgehend
von einem technologischen Trend bzw. einer Klasse innovativer Werkzeuge (bspw.
mobile Technologien). Es geht dann darum, die Potenziale dieser Tools für das
Lernen zu ergründen, also letztlich eine Passung zwischen den technologischen
Möglichkeiten und pädagogisch-didaktischen Erfordernissen zu konstruieren. In
diesem Beitrag kehren wir diese Perspektive um: Ausgehend von einer bestimmten
pädagogischen Problemstellung - der Bearbeitung heterogener Lernvoraussetzungen
und Studienerfahrungen in der Lehrerbildung - entwickeln wir unterschiedliche
didaktische Handlungsoptionen. Am Ende entsteht ein Werkzeug, das sich in Design
und Funktionsumfang auf den Kern der pädagogischen Zielsetzung beschränkt.'

text: Eine zentrale Herausforderung in der Ausbildung angehender Wirtschaftslehrpersonen
stellt die sinnvolle Verknüpfung von Theorie- und Praxiserfahrungen dar. Im Rahmen
der Ausbildung angehender Wirtschaftslehrpersonen an der Universität St. Gallen
wird eine Lernumgebung gestaltet, die eine Verschränkung von Theorie- und Praxiserfahrungen
ermöglichen soll. Die Lernprozesse der Studierenden werden dabei durch didaktisch
angeleitete Weblogarbeit unterstützt. Trotz der Lernchancen, die sich aus einer
Verknüpfung von theoretischen und praktischen Lernphasen ergeben, schätzen die
Studierenden den Nutzen der Weblogarbeit als äusserst gering ein. Die Studierenden
bei der reflexiven Integration praxisnaher und theoretischer Lernerfahrungen zu
unterstützen, ist eine Herausforderung, die dezidierter Anleitung und Förderung
durch die Lehrpersonen bedarf

text: Remote voting through the Internet provides convenience and access to the
electorate. At the same time, the security concerns facing any distributed application
are magnified when the task is so crucial to democratic society. In addition,
some of the electoral process loses transparency when it is encapsulated in information
technology. In this paper, we examine the public record of three recent elections
that used Internet voting. Our specific goal is to identify any potential flaws
that security experts would recognize, but may have not been identified in the
rush to implement technology. To do this, we present a multiple exploratory case
study, looking at elections conducted between 2006 and 2007 in Estonia, Netherlands,
and Switzerland. These elections were selected as particularly interesting and
accessible, and each presents its own technical and security challenges. The electoral
environment, technical design and process for each election are described, including
reconstruction of details which are implied but not specified within the source
material. We found that all three elections warrant significant concern about
voter security, verifiability, and transparency. Usability, our fourth area of
focus, seems to have been well-addressed in these elections. While our analysis
is based on public documents and previously published reports, and therefore lacking
access to any confidential materials held by electoral officials, this comparative
analysis provides interesting insight and consistent questions across all these
cases. Effective review of Internet voting requires an aggressive stance towards
identifying potential security and operational flaws, and we encourage the use
of third party reviews with critical technology skills during design, programming,
and voting to reduce the changes of failure or fraud that would undermine public
confidence.

text: Spam e-mails have become a serious technological and economic problem. Up
to now, by deploying complementary anti-spam measures, we have been reasonably
able to withstand spam e-mails and use the Internet for regular communication.
However, if we are to avert the danger of losing the Internet e-mail service in
its capacity as a valuable, free and worldwide medium of open communication, anti-spam
activities should be performed more systematically than is currently the case
regarding the mainly heuristic, anti-spam measures in place. A formal framework,
within which the existing delivery routes that a spam e-mail may take, and anti-spam
measures and their effectiveness can be investigated, will perhaps encourage a
shift in methodology and pave the way for new, holistic anti-spam measures. This
paper presents a model of the Internet e-mail infrastructure as a directed graph
and a deterministic finite automaton and draws on automata theory to formally
derive the spam delivery routes. The most important anti-spam measures are then
described. Methods controlling only specific delivery routes are evaluated in
terms of how effectively they cover the modeled e-mail infrastructure; methods
operating independently of any particular routes receive a more general assessment.

text: Spam has become one of the most annoying and costly phenomenon in the Internet.
Valid e-mail addresses belong to the most valuable resources of spammers, but
little is known about spammers? behavior when collecting and harvesting addresses
and spammers? capabilities and interest in carefully directed, consumer-oriented
marketing have not been explored yet. Gaining insight into spammers? ways to obtain
and (mis)use e-mail addresses is useful in many ways, e.g. for the assessment
of the effectiveness of address obscuring techniques and the usability and necessity
of hiding e-mail addresses on the Internet. This paper presents a spam honeypot
project in progress addressing these issues by systematically placing e-mail addresses
in the Internet and analyzing received e-mails. The honeypot?s conceptual framework,
its implementation, and first empirical results are presented. Finally, an outlook
on further work and activities is provided.

text: Spam als unerwünschte Massen-E-Mail hat die Grenze von der Belästigung zur
ökonomischen Relevanz längst überschritten. Ihr relativer Anteil am gesamten,
weltweiten E-Mail-Aufkommen stieg in den vergangenen Jahren auf mehr als 50% im
Jahr 2003. Es entstehen jährlich volkswirtschaftliche Schäden in Milliardenhöhe.
Zur Bekämpfung des Spam-Problems werden neben gesetzlichen Regelungen vor allem
technische Lösungen eingesetzt, bei denen das Blockieren und Filtern von E-Mails
in praktisch eingesetzten Anti-Spam-Systemen dominieren. Dieser Artikel führt
in die Spam-Problematik ein und beschreibt, bewertet und klassifiziert die derzeit
bedeutendsten Verfahren zur Bekämpfung von Spam.

text: Spam as unsolicited e-mail to a large number of recipients is known to ecome
an increasingly disturbing and costly issue of electronic business and internet
traffic. Mainly technical-oriented approaches are applied with a focus on blocking,
filtering, and authentication mechanisms based on the domain name system. They
come along with different drawbacks and have all low effectiveness in common.
The article sketches these approaches, shows its limitations, and proposes an
account-based approach where the number of e-mails per day and account is restricted.

text: Voting via the Internet is part of electronic government and electronic democracy.
However, there are many obstacles which have to be overcome, especially legal
restrictions have to be transformed into technical and security solutions. In
the first part the article discusses advantages and disadvantages of Internet
elections, shows different application fields, and presents important international
pilot schemes (political and business ones). in the second part, due to democratic
basic principles, technological security aspects are worked out.

text: 'Zusammenfassung: Im Rahmen des E-Governments werden zunehmend Internetwahlen
diskutiert. Der Beitrag diskutiert zunächst die Vor- und Nachteile derartiger
Wahlen und zeigt Anwendungsgebiete sowie durchgeführte Pilotprojekte im politischen
wie auch wirtschaftlichen Bereich auf. Im Rahmen eines Anforderungssystems werden
anschließend aus demokratischen Wahlgrundsätzen sicherheitstechnologische Anforderungen
herausgearbeitet. Zu deren Adressierung werden kryptographischen Wahlkonzepte
herangezogen, von denen die wichtigsten vorgestellt werden. Aufgrund der Komplexität
der Anforderungslandschaft wird ein sicherheitstechnologisches Strukturmodell
vorgestellt, das insbesondere dazu dient, die Sicherheit(skomponenten) eines Wahlsystems
systematisch mit den Anforderungen abzugleichen. Der Artikel schließt mit einem
Ausblick auf notwendige Untersuchungen.'
