text: "Purpose\r\n– The purpose of this paper is to craft a future research agenda
to advance smart service research and practice. Smart services are delivered to
or via intelligent objects that feature awareness and connectivity. For service
researchers and managers, one of the most fascinating aspects of smart service
provision is that the connected object is able to sense its own condition and
its surroundings and thus allows for real-time data collection, continuous communication
and interactive feedback. \r\n\r\nDesign/methodology/approach\r\n– This article
is based on discussions in the workshop on “Fresh perspectives on technology in
service” at the International Network of Service Researchers on September 26,
2014 at CTF, Karlstad, Sweden. The paper summarizes the discussion on smart services,
adds an extensive literature review, provides examples from business practice
and develops a structured approach to new research avenues. \r\n\r\nFindings\r\n–
We propose that smart services vary on their individual level of autonomous decision-making,
visibility and embeddedness in objects and customer lives. Based on a discussion
of these characteristics, we identify research avenues regarding the perception
and nature of smart services, the adoption of smart services, the innovation through
smart services as well as regarding the development of new business models. \r\n\r\nOriginality/value\r\n–
Smart services is a new emerging topic in service marketing research, their implications
on organizations, customers and the service landscape have not been fully explored.
We provide a fresh perspective on service research by characterizing relevant
aspects of smart service that will stimulate fruitful future research and advance
the understanding and practice of smart services."

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: Coalition loyalty programs are on the rise, yet few studies investigate the
impact of service failures in such programs. Using data from a retail context,
the authors show that a program partner deemed responsible for a service failure
suffers negative customer responses. However, customers’ perceptions of the benefits
of the coalition loyalty program buffer these consequences. Perhaps most importantly,
when customers perceive the program's special treatment benefits as low, direct
and indirect spillover effects occur, such that a service failure by one program
partner has a negative effect on customer loyalty toward the program itself.

text: Smart interactive services, in contrast with other technology-based services,
require significant human-to-human interaction and collaboration in addition to
the service provided by the embedded technology itself. The authors’ foundational
Delphi study confirms smart interactive services (e.g., remote diagnosis, remote
repair of equipment, and telemedicine) are a rapidly growing innovation category
across industries. Yet, gaining user acceptance of these types of services presents
a significant challenge for managers. To address this challenge, the authors employ
a grounded theory approach, drawing on depth interviews, to develop a framework
of barriers and facilitators to users’ attitudinal and behavioral responses to
smart interactive services. The findings reveal a new set of beliefs that are
critical in this context. These beliefs are tied to the human element and specifically
pertain to beliefs about the “service counterpart (SC),” who is the provider’s
employee controlling the technology. Control, trustworthiness, and collaboration
beliefs emerge jointly as important and interrelated influencers tied to the SC.
Contrary to conventional wisdom that focuses on features of the technology itself
to gain user acceptance, this research encourages providers to emphasize the interpersonal
elements of the service by providing control cues, raising social presence, and
enhancing human trust mechanisms.

text: The tendency of managers to focus on short-term results rather than on sustained
company success is of particular importance to retail marketing managers, because
marketing activities involve expenditures which may only pay off in the longer
term. To address the issue of myopic management, our study shows how the complexity
of the service profit chain (SPC) can cause managers to make suboptimal decisions.
Hence, our paper departs from past research by recognizing that understanding
the temporal interplay between operational investments, employee satisfaction,
customer satisfaction, and operating profit is essential to achieving sustained
success. In particular, we intend to improve understanding of the functioning
of the SPC with respect to time lags and feedback loops. Results of our large-scale
longitudinal study set in a multi-outlet retail chain reveal time-lag effects
between operational investments and employee satisfaction, as well as between
customer satisfaction and performance. These findings, along with evidence of
a negative interaction effect of employee satisfaction on the relationship between
current performance and future investments, show the substantial risk of mismanaging
the SPC. We identify specific situations in which the dynamic approach leads to
superior marketing investment decisions, when compared to the conventional static
view of the SCP. These insights provide valuable managerial guidance for effectively
managing the SPC over time.

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: For an environment to be perceived as being smart, contextual information
has to be gathered to adapt the system's behavior and its interface towards the
user. Being a rich source of context information speech can be acquired unobtrusively
by microphone arrays and then processed to extract information about the user
and his environment. In this paper, a system for joint temporal segmentation,
speaker localization, and identification is presented, which is supported by face
identification from video data obtained from a steerable camera. Special attention
is paid to latency aspects and online processing capabilities, as they are important
for the application under investigation, namely ambient communication. It describes
the vision of terminal-less, session-less and multi-modal telecommunication with
remote partners, where the user can move freely within his home while the communication
follows him. The speaker diarization serves as a context source, which has been
integrated in a service-oriented middleware architecture and provided to the application
to select the most appropriate I/O device and to steer the camera towards the
speaker during ambient communication.

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: This paper investigates the influence of feedback provided by an autonomous
robot (BIRON) on users’ discursive behavior. A user study is described during
which users show objects to the robot. The results of the experiment indicate,
that the robot’s verbal feedback utterances cause the humans to adapt their own
way of speaking. The changes in users’ verbal behavior are due to their beliefs
about the robots knowledge and abilities. In this paper they are identified and
grouped. Moreover, the data implies variations in user behavior regarding gestures.
Unlike speech, the robot was not able to give feedback with gestures. Due to the
lack of feedback, users did not seem to have a consistent mental representation
of the robot’s abilities to recognize gestures. As a result, changes between different
gestures are interpreted to be unconscious variations accompanying speech.

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: "Nearly all existing HPC systems are operated by resource management systems
based on the queuing approach. With the increasing acceptance of grid middleware
like Globus, new requirements for the underlying local resource management systems
arise. Features like advanced reservation or quality of service are needed to
implement high level functions like co-allocation. However it is difficult to
realize these features with a resource management system based on the queuing
concept since it considers only the present resource usage.\r\n\r\nIn this paper
we present an approach which closes this gap. By assigning start times to each
resource request, a complete schedule is planned. Advanced reservations are now
easily possible. Based on this planning approach functions like diffuse requests,
automatic duration extension, or service level agreements are described. We think
they are useful to increase the usability, acceptance and performance of HPC machines.
In the second part of this paper we present a planning based resource management
system which already covers some of the mentioned features."
