text: Children’s information-related internet use positively affects their acquisition
of computer- and information-related skills. Nevertheless, this use still occurs
predominantly in the family context. Parents’ support of their children’s internet
use can motivate them to use the internet for information-related purposes. However,
while parents’ support seems to be important, the quantity and quality of parental
support have been shown to have different associations with children’s motivation.
Thus, the goal of the current study was to examine the relationship between parents’
support (quantity and quality), children’s motivation to engage in information-related
internet use, and children’s actual information-related internet use (practical
and school- or learning-related use) using structural equation modeling. In addition,
we examined the mediating effects of children’s motivation. Specifically, 492
12-year-old German children answered a paper-and-pencil questionnaire. We found
positive associations between the quantity and quality of parents’ support and
children’s intrinsic and extrinsic motivation, while only structure-giving support
was found to be related to children’s intrinsic motivation. The quantity of support
was directly related to children’s school- or learning-related use, while intrinsic
motivation was associated with both forms of information-related internet use.
Furthermore, we confirmed that children’s motivation is an important mediator
in this context. The implications of these findings for parents and children are
considered.

text: Recent years have seen the emergence of physical products that are digitally
networked with other products and with information systems to enable complex business
scenarios in manufacturing, mobility, or healthcare. These “smart products”, which
enable the co-creation of “smart service” that is based on monitoring, optimization,
remote control, and autonomous adaptation of products, profoundly transform service
systems into what we call “smart service systems”. In a multi-method study that
includes conceptual research and qualitative data from in-depth interviews, we
conceptualize “smart service” and “smart service systems” based on using smart
products as boundary objects that integrate service consumers’ and service providers’
resources and activities. Smart products allow both actors to retrieve and to
analyze aggregated field evidence and to adapt service systems based on contextual
data. We discuss the implications that the introduction of smart service systems
have for foundational concepts of service science and conclude that smart service
systems are characterized by technology-mediated, continuous, and routinized interactions.

text: In this paper, we present an IoT architecture which handles stream sensor
data of air pollution. Particle pollution is known as a serious threat to human
health. Along with developments in the use of wireless sensors and the IoT, we
propose an architecture that flexibly measures and processes stream data collected
in real-time by movable and low-cost IoT sensors. Thus, it enables a wide-spread
network of wireless sensors that can follow changes in human behavior. Apart from
stating reasons for the need of such a development and its requirements, we provide
a conceptual design as well as a technological design of such an architecture.
The technological design consists of Kaa and Apache Storm which can collect air
pollution information in real-time and solve various problems to process data
such as missing data and synchronization. This enables us to add a simulation
in which we provide issues that might come up when having our architecture in
use. Together with these issues, we state r easons for choosing specific modules
among candidates. Our architecture combines wireless sensors with the Kaa IoT
framework, an Apache Kafka pipeline and an Apache Storm Data Stream Management
System among others. We even provide open-government data sets that are freely
available.

text: Emerging digital environments and infrastructures, such as distributed services
and computing services, have generated new options of communication, information
sharing, and resource utilization in past years. Different distributed trust concepts
are applied to increase trust in such systems. However, these concepts yield to
rather complex architectures which make it difficult to determine which component
or system needs to be trusted. This paper presents a novel trust measurement method
for distributed systems which enables the t identification of weak points in the
overall system architecture. The measurement method includes the specification
of a formal trust language and its representation by means of propositional logic
formulas. The applicability of the proposed concepts is demonstrated by conducting
a case study on the Internet voting system that was used in the 2007 parliamentary
elections in Estonia.

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: The Estonian parliamentary election in 2007 is regarded as a success story
of large-scale Internet elections. I use this election in a single case study
on practical security to show that low quality of security and its management
does not necessarily prevent large-scale Internet elections from being conducted.
I also provide research propositions with regard to future challenges for large-scale
Internet elections.

text: In this paper, we derive an uncertainty decoding rule for automatic speech
recognition (ASR), which accounts for both corrupted observations and inter-frame
correlation. The conditional independence assumption, prevalent in hidden Markov
model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned
on the complete observed feature vector sequence. This is a more informative posterior
than one conditioned only on the current observation. The novel decoding is used
to obtain a transmission-error robust remote ASR system, where the speech capturing
unit is connected to the decoder via an error-prone communication network. We
show how the clean speech posterior can be computed for communication links being
characterized by either bit errors or packet loss. Recognition results are presented
for both distributed and network speech recognition, where in the latter case
common voice-over-IP codecs are employed.

text: Spamming remains a form of Internet abuse, which burdens the Internet infrastructure,
is generally regarded as an annoyance, and is said to cause a huge economic harm.
Many technological, organizational, and legislative anti-spam measures have already
been proposed and implemented, but have not led to any substantial decrease in
the number of spam e-mails. We propose a scalable and flexible infrastructure
framework that integrates several anti-spam measures and that features both a
technological and an organizational facet. The key element of our infrastructure
is a new organizational unit that reliably and transparently limits the number
of e-mails that can be sent per day and per account. We also analyze the proposed
framework in terms of its theoretical effectiveness, the required resources, and
its limitations.

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.'

text: CSCW systems like BSCW (Basic Support for Cooperative Work), HyperNews, and
Lotus Notes have been successfully introduced to support the cooperation of geographically
distributed work groups. Unfortunately, some of these software systems are not
flexible enough to be customized easily to the requirements of an individual user.
Most of the environments can only be configured by experts through complex programming.
In this article we introduce VIP space, a shared workspace space in the sense
of exchanging and processing shared objects between members of distributed work
groups. VIP space can be easily adapted to the user's individual views and needs
by means of a visual programming language. In VIP space, objects of the shared
workspace are moved by drag and drop between task fields. Task fields are programmed
by visual "if-then" rules applying a combination of icon- and form-based techniques.
When a document represented by an icon is dropped on a task field its rules are
checked and actions of the selected rules are excited. VIP space is finally demonstrated
in an Internet course application.
