text: While increasing digitalization enables multiple advantages for a
reliable operation of technical systems, a remaining challenge in the context
of condition monitoring is seen in suitable consideration of uncertainties affecting
the monitored system. Therefore, a suitable prognostic approach to predict the
remaining useful lifetime of complex technical systems is required. To handle
different kinds of uncertainties, a novel Multi-Model-Particle Filtering-based
prognostic approach is developed and evaluated by the use case of rubber-metal-elements.
These elements are maintained preventively due to the strong influence of uncertainties
on their behavior. In this paper, two measurement quantities are compared concerning
their ability to establish a prediction of the remaining useful lifetime of the
monitored elements and the influence of present uncertainties. Based on three
performance indices, the results are evaluated. A comparison with predictions
of a classical Particle Filter underlines the superiority of the developed Multi-Model-Particle
Filter. Finally, the value of the developed method for enabling condition monitoring
of technical systems related to uncertainties is given exemplary by a comparison
between the preventive and the predictive maintenance strategy for the use case.

text: "Purpose: This study aims at investigating how digitalisation (in the sense
of industry 4.0) has changed the work of farmers and how they experience the changes
from more traditional work to digitalised agriculture. It also investigates what
knowledge farmers require on digitalised farms and how they acquire it. Dairy
farming was used as domain of investigation since it, unlike other industries,
has strongly been affected by digitalisation throughout the last years.\r\n\r\nMethod:
Exploratory interviews with 10 livestock farmers working on digitalised dairy
farms were analysed using qualitative content analysis. A deductive and inductive
coding strategy was used. \r\n\r\nFindings: Farming work has changed from more
manual tasks towards symbol manipulation and data processing. Farmers must be
able to use computers and other digital devices to retrieve and analyse sensor
data that allow them to monitor and control the processes on their farm. For this
new kind of work, farmers require elaborated mental models that link traditional
farming knowledge with knowledge about digital systems, including a strong understanding
of production processes underlying their farm. Learning is mostly based on instructions
offered by manufacturers of the new technology as well as informal and non-formal
learning modes. Even younger farmers report that digital technology was not sufficiently
covered in their (vocational) degrees. In general, farmers emphasises the positive
effects of digitalisation both on their working as well as private life. \r\n\r\nConclusions:
Farmers should be aware of the opportunities as well as the potential drawbacks
of the digitalisation of work processes in agriculture. Providers of agricultural
education (like vocational schools or training institutes) need to incorporate
the knowledge and skills required to work in digitalised environments (e.g., data
literacy) in their syllabi. Further studies are required to assess how digitalisation
changes farming practices and what knowledge as well as skills linked to these
developments are required in the future."

text: This study examines the relation between voluntary audit and the cost of debt
in private firms. We use a sample of 4,058 small private firms operating in the
period 2006‐2017 that are not subject to mandatory audits. Firms decide for a
voluntary audit of financial statements either because the economic setting in
which they operate effectively forces them to do so (e.g., ownership complexity,
export‐oriented supply chain, subsidiary status) or because firm fundamentals
and/or financial reporting practices limit their access to financial debt, both
reflected in earnings quality. We use these factors to model the decision for
voluntary audit. In the outcome analyses, we find robust evidence that voluntary
audits are associated with higher, rather than lower, interest rate by up to 3.0
percentage points. This effect is present regardless of the perceived audit quality
(Big‐4 vs. non‐Big‐4), but is stronger for non‐Big‐4 audits where auditees have
a stronger position relative to auditors. Audited firms’ earnings are less informative
about future operating performance relative to unaudited counterparts. We conclude
that voluntary audits facilitate access to financial debt for firms with higher
risk that may otherwise have no access to this form of financing. The price paid
is reflected in higher interest rates charged to firms with voluntary audits –
firms with higher information and/or fundamental risk.

text: 'Challenges in decisions on technical changes are the lack of knowledge about
the expected impact and change propagation. Currently, no literature study contains
a systematic differentiation and evaluation of existing approaches, which is a
prerequisite for practitioners to select a suitable approach. This research aims
at defining differentiation criteria as well as generally applicable requirements
for evaluation. A four-step approach is used: systematic literature review on
approaches for impact analysis of engineering changes (1), categorization and
prioritization of approaches based on reoccuring elements (2), derivation of context
specific requirements for evaluation (3), and evaluation of approaches (4). The
result indicates existing potential of object-oriented modeling approaches.'

text: "Finding a good query plan is key to the optimization of query runtime. This
holds in particular for cost-based federation\r\nengines, which make use of cardinality
estimations to achieve this goal. A number of studies compare SPARQL federation
engines across different performance metrics, including query runtime, result
set completeness and correctness, number of sources selected and number of requests
sent. Albeit informative, these metrics are generic and unable to quantify and
evaluate the accuracy of the cardinality estimators of cost-based federation engines.
To thoroughly evaluate cost-based federation engines, the effect of estimated
cardinality errors on the overall query runtime performance must be measured.
In this paper, we address this challenge by presenting novel evaluation metrics
targeted at a fine-grained benchmarking of cost-based federated SPARQL query engines.
We evaluate five cost-based federated SPARQL query engines using existing as well
as novel evaluation metrics by using LargeRDFBench queries. Our results provide
a detailed analysis of the experimental outcomes that reveal novel insights, useful
for the development of future cost-based federated SPARQL query processing engines."

text: Mobile shopping apps have been using Augmented Reality (AR) in the last years
to place their products in the environment of the customer. While this is possible
with atomic 3D objects, there is is still a lack in the runtime configuration of
3D object compositions based on user needs and environmental constraints. For
this, we previously developed an approach for model-based AR-assisted product
configuration based on the concept of Dynamic Software Product Lines. In this demonstration
paper, we present the corresponding tool support ProConAR in the form of a Product
Modeler and a Product Configurator. While the Product Modeler is an Angular web
app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table
legs, funnier) and saves it within a configuration model, the Product Configurator
is an Android client that uses the configuration model to place different product
configurations within the environment of the customer. We show technical details
of our ready to use tool-chain ProConAR by describing its implementation and usage
as well as pointing out future research directions.

text: 'To build successful products, the developers have to adapt their product
features and business models to uncertain customer needs. This adaptation is part
of the research discipline of Hypotheses Engineering (HE) where customer needs
can be seen as hypotheses that need to be tested iteratively by conducting experiments
together with the customer. So far, modeling support and associated traceability
of this iterative process are missing. Both, in turn, are important to document
the adaptation to the customer needs and identify experiments that provide most
evidence to the customer needs. To target this issue, we introduce a model-based
HE approach with a twofold contribution: First, we develop a modeling language
that models hypotheses and experiments as interrelated hierarchies together with
a mapping between them. While the hypotheses are labeled with a score level of
their current evidence, the experiments are labeled with a score level of maximum
evidence that can be achieved during conduction. Second, we provide an iterative
process to determine experiments that offer the most evidence improvement to the
modeled hypotheses. We illustrate the usefulness of the approach with an example
of testing the business model of a mobile application.'

text: The scientific impact of research papers is multi-dimensional and can be determined
quantitatively by means of citation analysis and qualitatively by means of content
analysis. Accounting for the widely acknowledged limitations of pure citation
analysis, we adopt a knowledge-based perspective on scientific impact to develop
a methodology for content-based citation analysis which allows determining how
papers have enabled knowledge development in subsequent research (knowledge impact).
As knowledge development differs between research genres, we develop a new knowledgebased
citation analysis methodology for the genre of standalone literature reviews (LRs).
We apply the suggested methodology to the IS business value domain by manually
coding 22 LRs and 1,228 citing papers (CPs) and show that the results challenge
the assumption that citations indicate knowledge impact. We derive implications
for distinguishing knowledge impact from citation impact in the LR genre. Finally,
we develop recommendations for authors of LRs, scientific evaluation committees
and editorial boards of journals how to apply and benefit from the suggested methodology,
and we discuss its efficiency and automatization.

text: This paper deals with aspect phrase extraction and classification in sentiment
analysis. We summarize current approaches and datasets from the domain of aspect-based
sentiment analysis. This domain detects sentiments expressed for individual aspects
in unstructured text data. So far, mainly commercial user reviews for products
or services such as restaurants were investigated. We here present our dataset
consisting of German physician reviews, a sensitive and linguistically complex
field. Furthermore, we describe the annotation process of a dataset for supervised
learning with neural networks. Moreover, we introduce our model for extracting
and classifying aspect phrases in one step, which obtains an F1-score of 80%.
By applying it to a more complex domain, our approach and results outperform previous
approaches.

text: "Literature reviews (LRs) play an important role in the development of domain
knowledge in all fields. Yet, we observe a\r\nlack of insights into the activities
with which LRs actually develop knowledge. To address this important gap, we (1)\r\nderive
knowledge building activities from the extant literature on LRs, (2) suggest a
knowledge-based typology of LRs\r\nthat complements existing typologies, and (3)
apply the suggested typology in an empirical study that explores how LRs\r\nwith
different goals and methodologies have contributed to knowledge development. The
analysis of 240 LRs published\r\nin 40 renowned IS journals between 2000 and 2014
allows us to draw a detailed picture of knowledge development\r\nachieved by one
of the most important genres in the IS field. An overarching contribution of our
work is to unify extant\r\nconceptualizations of LRs by clarifying and illustrating
how LRs apply different methodologies in a range of knowledge\r\nbuilding activities
to achieve their goals with respect to theory."

text: Sequential model-based optimization (SMBO) approaches are algorithms for solving
problems that require computationally or otherwise expensive function evaluations.
The key design principle of SMBO is a substitution of the true objective function
by a surrogate, which is used to propose the point(s) to be evaluated next. SMBO
algorithms are intrinsically modular, leaving the user with many important design
choices. Significant research efforts go into understanding which settings perform
best for which type of problems. Most works, however, focus on the choice of the
model, the acquisition function, and the strategy used to optimize the latter.
The choice of the initial sampling strategy, however, receives much less attention.
Not surprisingly, quite diverging recommendations can be found in the literature.
We analyze in this work how the size and the distribution of the initial sample
influences the overall quality of the efficient global optimization (EGO) algorithm,
a well-known SMBO approach. While, overall, small initial budgets using Halton
sampling seem preferable, we also observe that the performance landscape is rather
unstructured. We furthermore identify several situations in which EGO performs
unfavorably against random sampling. Both observations indicate that an adaptive
SMBO design could be beneficial, making SMBO an interesting test-bed for automated
algorithm design.

(TSP) and two highly competitive inexact heuristic TSP solvers, EAX and LKH, in
the context of per-instance algorithm selection (AS). We evolve instances with
nodes where the solvers show strongly different performance profiles. These instances
serve as a basis for an exploratory study on the identification of well-discriminating
problem characteristics (features). Our results in a nutshell: we show that even
though (1) promising features exist, (2) these are in line with previous results
from the literature, and (3) models trained with these features are more accurate
than models adopting sophisticated feature selection methods, the advantage is
not close to the virtual best solver in terms of penalized average runtime and
so is the performance gain over the single best solver. However, we show that
a feature-free deep neural network based approach solely based on visual representation
of the instances already matches classical AS model results and thus shows huge
potential for future studies.'

text: Manufacturers increasingly integrate information and communication technologies
into their products so that they can provide IT-based services. Organizations
that formerly concentrated on transactional sales thus confront a new challenge
associated with managing service usage—retention and extracting value from investments
in smart technology. This study combines a marketing and an information systems
perspective in a field study conducted jointly with a large European car manufacturer.
Understanding the renewal decision for IT-based service contracts requires knowledge
from both disciplines. The paper shows that combining behavioral predictor variables
stemming from marketing research and technology-related perceptual variables stemming
from technology acceptance research increases the explanatory power and prediction
accuracy of forecasting models for customer renewal decisions. Specifically, the
authors show that perceptions of usefulness become more important the longer customers
use IT-based services and the more services they use within the service contract.

text: Piezoelectric transducers are used in a wide range of applications. Reliability
of these transducers is an important aspect in their application. Prognostics,
which involve continuous monitoring of the health of technical systems and using
this information to estimate the current health state and consequently predict
the remaining useful lifetime (RUL), can be used to increase the reliability,
safety, and availability of the transducers. This is achieved by utilizing the
health state and RUL predictions to adaptively control the usage of the components
or to schedule appropriate maintenance without interrupting operation. In this
work, a prognostic approach utilizing self-sensing, where electric signals of
a piezoelectric transducer are used as the condition monitoring data, is proposed.
The approach involves training machine learning algorithms to model the degradation
of the transducers through a health index and the use of the learned model to
estimate the health index of similar transducers. The current health index is
then used to estimate RUL of test components. The feasibility of the approach
is demonstrated using piezoelectric bimorphs and the results show that the method
is accurate in predicting the health index and RUL.

text: 'Recent studies highlight early childhood teachers’ mathematics-related competence.
Developing this competence should be a main aspect of early childhood teachers’
education. This is, however, not the case in all countries. Consequently, high-quality
professional development courses are needed. Based on research results, we developed
a competence-oriented continuous professional development course ("EmMa") and
examined the effects of "EmMa" by asking: How does "EmMa" affect the development
of early childhood teachers’ i) mathematical content knowledge, ii) mathematical
pedagogical content knowledge and iii) beliefs towards mathematics in general?
To answer these questions, we conducted a pre-test/post-test study including a
control group with 99 in-service early childhood teachers. Results show that the
course affected teachers’ mathematical pedagogical content knowledge and static
orientation towards mathematics positively. From this we conclude that scaling-up
"EmMa" might be a suitable approach to bridge the gap between pre-service education
with nearly no mathematics and the challenges of early mathematics education.'

text: One purpose of requirement refinement is that higher-level requirements have
to be translated to something usable by developers. Since customer requirements
are often written in natural language by end users, they lack precision, completeness
and consistency. Although user stories are often used in the requirement elicitation
process in order to describe the possibilities how to interact with the software,
there is always something unspoken. Here, we present techniques how to automatically
refine vague software descriptions. Thus, we can bridge the gap by first revising
natural language utterances from higher-level to more detailed customer requirements,
before functionality matters. We therefore focus on the resolution of semantically
incomplete user-generated sentences (i.e. non-instantiated arguments of predicates)
and provide ontology-based gap-filling suggestions how to complete unverbalized
information in the user’s demand.

text: 'This study examines the loan-pricing behavior of German banks for a large
variety of retail and corporate loan products. We find that a bank’s operational
efficiency is priced in bank loan rates and alters interest-setting behavior.
Specifically, we establish that a higher degree of operational efficiency leads
to lower loan markups, which makes prices more competitive and smoothes the setting
of interest rates. By employing state-of-the-art stochastic frontier efficiency
measures to capture a bank’s operational efficiency, we take a look at the bank
customers’ perspective and demonstrate the extent to which bor-rowers benefit
from cost-efficient banking. '
