text: This paper presents an advanced eight levels spanning SystemC based virtual
platform methodology and framework - referred to as HeroeS 3 - providing smooth
application to platform mapping and continuous co-refinement of a virtual prototype
with its physical environment model. For heterogeneity support, various SystemC
extensions are combined covering continuous/discrete models of computation and
different communication abstractions, such as analog mixed-signal models, abstract
RTOS/HAL/middleware models, TLM bus models, and QEMU wrappers. We enable dependability
assessment by Fault Effect Modeling (FEM) at the virtual prototype in order to
avoid risking physical injury or damage. Also, simulation results are deterministic
and can be evaluated interactively or offline. We apply FEM to both the physical
environment model and the different abstractions of the virtual prototype. Currently,
we focus on sensor failures and application control flow errors.

text: 'Research of tutoring in parent-infant interaction has shown that tutors -
when presenting some action - modify both their verbal and manual performance
for the learner (‘motherese’, ‘motionese’). Investigating the sources and effects
of the tutors’ action modifications, we suggest an interactional account of ‘motionese’.
Using video-data from a semi-experimental study in which parents taught their
8 to 11 month old infants how to nest a set of differently sized cups, we found
that the tutors’ action modifications (in particular: high arches) functioned
as an orienting device to guide the infant’s visual attention (gaze). Action modification
and the recipient’s gaze can be seen to have a reciprocal sequential relationship
and to constitute a constant loop of mutual adjustments. Implications are discussed
for developmental research and for robotic ‘Social Learning’. We argue that a
robot system could use on-line feedback strategies (e.g. gaze) to pro-actively
shape a tutor’s action presentation as it emerges.'

text: "The proposed paper aims to investigate the longitudinal development of students'
motivation over the first year of their studies at a business school by using
latent growth curve modeling. The study tackles the following core research questions:
How do first-year university students' intrinsic and extrinsic vary over time?
Which (motivational) factors are related to students' motivational development?
Although motivational dispositions have been analyzed extensively in previous
studies, their longitudinal development has hitherto not been examined in the
higher education context.\r\n\r\nThis longitudinal study is conducted at the University
of St. Gallen in Switzerland. The current sample includes 280 first-year students
who have been surveyed three times and who are representative of the first-year
student population.\r\n\r\nDescriptive results show that prior to their studies,
students were motivated most by intrinsic factors, however, extrinsic motivation
was also quite high. Employing latent growth curve modeling, it could be shown
that both intrinsic and extrinsic motivation decline significantly over the course
of the first year (8 months).\r\n\r\nThe study contributes to motivation theory
by providing further insights into the development of academic motivation over
time. Latent growth curve modeling as a method can be well used for longitudinal
data analysis, thus, excluding measurement error from longitudinal data. Furthermore,
the study supports educational developers by determining factors influencing students'
motivational development."

text: In this paper we present a speech presence probability (SPP) estimation algorithmwhich
exploits both temporal and spectral correlations of speech. To this end, the SPP
estimation is formulated as the posterior probability estimation of the states
of a two-dimensional (2D) Hidden Markov Model (HMM). We derive an iterative algorithm
to decode the 2D-HMM which is based on the turbo principle. The experimental results
show that indeed the SPP estimates improve from iteration to iteration, and further
clearly outperform another state-of-the-art SPP estimation algorithm.

text: Previous research suggests the existence of sentiments in online social networks.
In comparison to real life human interaction, in which sentiments have been shown
to have an influence on human behaviour, it is not yet completely understood which
mechanisms explain how sentiments influence users in online environments. We develop
a theoretical framework that tries to bridge the gap between social influence
theories that focus on offline interactions on one hand and online interaction
in social networks on the other hand. We then test our hypothesis about the influence
and dissemination of sentiments in a quantitative analysis that is based on retrieved
textual messages of communication patterns in over 12000 online social networks.
Our empirical results suggest a general influence of sentiments on node communication
patterns that is evidenced by increased occurrences of subsequent messages that
express the same sentiment polarization. We interpret these findings and suggest
future research to advance our currently limited theories that assume perceived
and generalized social influence to path-dependent social influence models that
consider actual behaviour.

text: Faced with increasing demands on energy efficiency, current electronic systems
operate according to complex power management schemes including more and more
fine-grained voltage frequency scaling and power shutdown scenarios. Consequently,
validation of the power design intent should begin as early as possible at electronic
system-level (ESL) together with first executable system specifications for integrity
tests. However, today's system-level design methodologies usually focus on the
abstraction of digital logic and time, so that typical low-power aspects cannot
be considered so far. In this paper, we present a high-level modeling approach
on top of the SystemC/TLM standard to simulate power distribution and voltage
based implications in a "loosely-timed" functional execution context. The approach
reuses legacy TLM models and prevents the need for detailed lock-step process
synchronization in contrast to existing methods. A case study derived from an
open source low-power design demonstrates the efficiency of our approach in terms
of simulation performance and testability.

text: Communication within online social network applications enables users to express
and share sentiments electronically. Existing studies examined the existence or
distribution of sentiments in online communication at a general level or in small-observed
groups. Our paper extends this research by analyzing sentiment exchange within
social networks from an ego-network perspective. We draw from research on social
influence and social attachment to develop theories of node polarization, balance
effects and sentiment mirroring within communication dyads. Our empirical analysis
covers a multitude of social networks in which the sentiment valence of all messages
was determined. Subsequently we studied ego-networks of focal actors (ego) and
their immediate contacts. Results support our theories and indicate that actors
develop polarized sentiments towards individual peers but keep sentiment in balance
on the ego-network level. Further, pairs of nodes tend to establish similar attitudes
towards each other leading to stable and polarized positive or negative relationships

text: Communication in online social networks has been analyzed for some time regarding
the expression of sentiments. So far, very little is known about the relationship
between sentiments and network emergence, dissemination patternsand possible differences
between positive and negative sentiments. The dissemination patterns analyzed
in this study consist of network motifs based on triples of actors and the ties
among them. These motifs are associated with common social network effects to
derive meaningful insights about dissemination activities. The data basis includes
several thousand social networks with textual messages classified according to
embedded positive and negative sentiments. Based on this data, sub-networks are
extracted and analyzed with a dynamic network motif analysis to determine dissemination
patterns and associated network effects. Results indicate that the emergence of
digital social networks exhibits a strong tendency towards reciprocity, followed
by the dominance ofhierarchy as an intermediate step leading to social clustering
with hubs and transitivity effects for both positive and negative sentiments to
the same extend. Sentiments embedded in exchanged textual messages do only play
a secondary role in network emergence and do not express differences regarding
the emergence of network patterns.

text: The steady supply of new optimization methods makes the algorithm selection
problem (ASP) an increasingly pressing and challenging task, specially for real-world
black-box optimization problems. The introduced approach considers the ASP as
a cost-sensitive classification task which is based on Exploratory Landscape Analysis.
Low-level features gathered by systematic sampling of the function on the feasible
set are used to predict a well-performing algorithm out of a given portfolio.
Example-specific label costs are defined by the expected runtime of each candidate
algorithm. We use one-sided support vector regression to solve this learning problem.
The approach is illustrated by means of the optimization problems and algorithms
of the BBOB’09/10 workshop.

text: Exploratory Landscape Analysis subsumes a number of techniques employed to
obtain knowledge about the properties of an unknown optimization problem, especially
insofar as these properties are important for the performance of optimization
algorithms. Where in a first attempt, one could rely on high-level features designed
by experts, we approach the problem from a different angle here, namely by using
relatively cheap low-level computer generated features. Interestingly, very few
features are needed to separate the BBOB problem groups and also for relating
a problem to high-level, expert designed features, paving the way for automatic
algorithm selection.

text: This article investigates forms of address, in particular the T/V distinction
in German, in conversational interviews with German-speaking immigrants to English-speaking
Canada and their descendants. From among 77 interviews conducted in two urban
areas in Canada, we discuss instances of both the interactional use of and metalinguistic
comments on forms of address. Our analysis is largely guided by conversation analysis
and interactional sociolinguistics (e.g. Goodwin & Heritage 1990). Using Clyne,
Norrby and Warren’s (2009) model of address as a backdrop, we investigate the
construction of group identity and group socialization through the lens of positioning
theory (e.g. van Langenhove & Harré 1993; Dailey-O’Cain & Liebscher 2009). This
combination of analytical tools can explain shifts in both usage of and attitudes
toward the T/V distinction that cannot be explained through language attrition
arguments alone.

text: In this paper, we present a new technique for automatic speech recognition
(ASR) in reverberant environments. Our approach is aimed at the enhancement of
the logarithmic Mel power spectrum, which is computed at an intermediate stage
to obtain the widely used Mel frequency cepstral coefficients (MFCCs). Given the
reverberant logarithmic Mel power spectral coefficients (LMPSCs), a minimum mean
square error estimate of the clean LMPSCs is computed by carrying out Bayesian
inference. We employ switching linear dynamical models as an a priori model for
the dynamics of the clean LMPSCs. Further, we derive a stochastic observation
model which relates the clean to the reverberant LMPSCs through a simplified model
of the room impulse response (RIR). This model requires only two parameters, namely
RIR energy and reverberation time, which can be estimated from the captured microphone
signal. The performance of the proposed enhancement technique is studied on the
AURORA5 database and compared to that of constrained maximum-likelihood linear
regression (CMLLR). It is shown by experimental results that our approach significantly
outperforms CMLLR and that up to 80\% of the errors caused by the reverberation
are recovered. In addition to the fact that the approach is compatible with the
standard MFCC feature vectors, it leaves the ASR back-end unchanged. It is of
moderate computational complexity and suitable for real time applications.

text: 'Implicit change detection demonstrates how the visual system can benefit
from stored information that is not immediately available to conscious awareness.
We investigated the role of motor action in this context. In the first two experiments,
using a one-shot implicit change detection paradigm, participants responded to
unperceived changes either with an action (jabbing the screen at the guessed location
of a change) or with words (verbal report), and sat either 60 cm or 300 cm (with
a laser pointer) away from the display. Our observers guessed the locations of
changes at a reachable distance better with an action than with a verbal judgment.
At 300 cm, beyond reach, the motor advantage disappeared. In experiment 3, this
advantage was also unavailable when participants sat at a reachable distance but
responded with hand-held laser pointers near their bodies. We conclude that a
motor system specialized for real-time visually guided behavior has access to
additional visual information. '

text: Today, mobile and embedded real time systems have to cope with the migration
and allocation of multiple software tasks running on top of a real time operating
system (RTOS) residing on one or several processors. For scaling of each task
set and processor configuration, instruction set simulation and worst case timing
analysis are typically applied. This paper presents a complementary approach for
the verification of RTOS properties based on an abstract RTOS-Model in SystemC.
We apply IEEE P1850 PSL for which we present an approach and first experiences
for the assertion-based verification of RTOS properties.

text: Today we can identify a big gap between requirement specification and the
generation of test environments. This article extends the Classification Tree
Method for Embedded Systems (CTM/ES) to fill this gap by new concepts for the
precise specification of stimuli for operational ranges of continuous control
systems. It introduces novel means for continuous acceptance criteria definition
and for functional coverage definition.

text: In this paper, parameter estimation of a state-space model of noise or noisy
speech cepstra is investigated. A blockwise EM algorithm is derived for the estimation
of the state and observation noise covariance from noise-only input data. It is
supposed to be used during the offline training mode of a speech recognizer. Further
a sequential online EM algorithm is developed to adapt the observation noise covariance
on noisy speech cepstra at its input. The estimated parameters are then used in
model-based speech feature enhancement for noise-robust automatic speech recognition.
Experiments on the AURORA4 database lead to improved recognition results with
a linear state model compared to the assumption of stationary noise.
