text: As an effective and accurate method for modelling composite materials, mean-field
homogenization is still not well studied in modelling non-linear and damage behaviours
of UD composites. Investigated micro FE-simulations show that the matrix of UD
composites exhibits different average plastic behaviour, named as average asymmetric
matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal
and transverse loadings. In this study, a non-linear mean-field debonding model
(NMFDM) combining a mean-field model and a fibre–matrix interface debonding model,
is developed to simulate UD composites under consideration of AAMP, fibre–matrix
interface damage and progressive failure. AAMP is considered by using so-called
stress mode factor, which is expressed in terms of basic invariants of the matrix
deviatoric stress tensor and is used as an indicator for detection of differences
in the loading mode. The material behaviour of UD composites with imperfect interface
is assumed identical as for perfect interface and stiffness reduced fibres. Progressive
failure criteria are established with consideration of fibre breakage and matrix
crack for different fibre orientations. As a representative example for the NMFDM,
a C30/E201 UD composite is studied. To verify the model, experiments are conducted
on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate
a perforated CFRP laminate, which shows excellent prediction ability on deformation,
debonding and progressive failure.

text: 'Repetitive TMS (rTMS) with a frequency of 5-10~Hz is widely used for language
mapping. However, it may be accompanied by discomfort and is limited in the number
and reliability of evoked language errors. We, here, systematically tested the
influence of different stimulation frequencies (i.e., 10, 30, and 50 Hz) on tolerability,
number, reliability, and cortical distribution of language errors aiming at improved
language mapping. 15 right-handed, healthy subjects (m~=~8, median age: 29 yrs)
were investigated in two sessions, separated by 2-5 days. In each session, 10,
30, and 50 Hz rTMS were applied over the left hemisphere in a randomized order
during a picture naming task. Overall, 30 Hz rTMS evoked significantly more errors
(20 $\pm$ 12{%}) compared to 50 Hz (12 $\pm$ 8{%}; p {\textless}.01), whereas
error rates were comparable between 30/50 and 10~Hz (18 $\pm$ 11{%}). Across all
conditions, a significantly higher error rate was found in Session 1 (19 $\pm$
13{%}) compared to Session 2 (13 $\pm$ 7{%}, p {\textless}.05). The error rate
was poorly reliable between sessions for 10 (intraclass correlation coefficient,
ICC~=~.315) and 30 Hz (ICC~=~.427), whereas 50 Hz showed a moderate reliability
(ICC~=~.597). Spatial reliability of language errors was low to moderate with
a tendency toward increased reliability for higher frequencies, for example, within
frontal regions. Compared to 10~Hz, both, 30 and 50 Hz were rated as less painful.
Taken together, our data favor the use of rTMS-protocols employing higher frequencies
for evoking language errors reliably and with reduced discomfort, depending on
the region of interest.'

text: Timing plays a crucial role in the context of information security investments.
We regard timing in two dimensions, namely the time of announcement in relation
to the time of investment and the time of announcement in relation to the time
of a fundamental security incident. The financial value of information security
investments is assessed by examining the relationship between the investment announcements
and their stock market reaction focusing on the two time dimensions. Using an
event study methodology, we found that both dimensions influence the stock market
return of the investing organization. Our results indicate that (1) after fundamental
security incidents in a given industry, the stock price will react more positively
to a firm’s announcement of actual information security investments than to announcements
of the intention to invest; (2) the stock price will react more positively to
a firm’s announcements of the intention to invest after the fundamental security
incident compared to before; and (3) the stock price will react more positively
to a firm’s announcements of actual information security investments after the
fundamental security incident compared to before. Overall, the lowest abnormal
return can be expected when the intention to invest is announced before a fundamental
information security incident and the highest return when actual investing after
a fundamental information security incident in the respective industry.

text: 'Through co-occurrence analysis of 1139 documents (1964-2018) we identified
trends in the discussions about the implementation of student teaching evaluation
(SET). We found that: (1) Attention to SET originated in the US in the 1970s,
spreading to German-speaking countries in the mid-1990s and continuing in China
and Latin America in the early 2000s. (2) SET is commonly viewed as a control
tool deserving methodological improvement, while bias is debated in the US. We
also found local trajectories: (3) Whereas in the US and Latin America SET is
primarily seen as a management tool, German-speaking and Chinese authors reflect
more on improving teaching. Chinese scholars consider SET a valid instrument for
state control associated with artificial intelligence. Also, (4) SET is commonly
used in medical education in the US and the German-speaking region and in physical
education in China. We conclude that SET is discussed cross-nationally but affected
by national path dependencies.'

text: "Die Themen „Big Data“, „Künstliche Intelligenz und „Data Science“ werden
seit einiger Zeit nicht nur in der breiten Öffentlichkeit kontrovers diskutiert,
sondern stellen für die Ausbildung in den IT- und IT-nahen Berufen schon heute
neue Herausforderungen dar, die in Zukunft durch die gesellschaftliche und technologische
Weiterentwicklung hin zu einer Datengesellschaft noch größer werden.\r\nAn dieser
Stelle stellt sich die Frage, welche Aspekte dieses großen Themenkomplexes für
Schule und Ausbildung von Wichtigkeit sind und wie diese Themen sinnstiftend und
gewinnbringend in die informatische Ausbildung in verschiedenen Bildungsgängen
integriert werden können. Im Rahmen des von uns im Jahr 2017 organisierten Symposiums
zum Thema „Data Science“ wurden für die Bildung relevante Aspekte erörtert, wodurch
als Kernelemente für den Unterricht Algorithmen der Künstlichen Intelligenz und
ihre Anwendung in Industrie und Gesellschaft, Explorationen von Big Data sowie
der Umgang mit eigenen Daten in sozialen Netzwerken herausgearbeitet wurden. Ziel
ist, aus diesen Themenbereichen sowohl ein umfassendes Curriculum als auch Module
für verschiedene Unterrichtsszenarien zu entwickeln und zu erproben. Durch diese
Materialien soll es Lehrkräften aus der Informatik, Mathematik oder Technik ermöglicht
werden, diese Themen auf Basis des Curriculums und der erprobten Unterrichtskonzepte
selbst zu unterrichten.\r\nHierfür wurde im Rahmen des Projekts ProDaBi (Projekt
Data Science und Big Data in der Schule, https://www.prodabi.de), initiiert von
der Telekom Stiftung, ein experimenteller Projektkurs entwickelt, den wir mit
Schüler:innen der Sekundarstufe II an der Universität Paderborn im Schuljahr 2018/19
durchführten. Dieser Kurs enthält neben einem Modul zur Exploration von Big Data
und einem weiteren Modul zum Maschinellen Lernen als Teil der Künstlichen Intelligenz
auch eine Projektphase, die es in Zusammenarbeit mit lokalen Unternehmen den Schüler:innen\r\nermöglicht,
das Erlernte in ein reales Data Science-Projekt einzubringen. Aus den Erfahrungen
dieses Projektkurses sowie den parallel durchgeführten Erprobungen einzelner Bausteine
auch mit beruflichen Schulen werden ab dem Schuljahr 2019/20 die hierfür verwendeten
Materialien weiterentwickelt und weiteren Kooperationspartnern zur Erprobung zur
Verfügung gestellt. Damit wurden zum Ende des Projekts nicht nur vollständige
Unterrichtsmaterialien, sondern auch ein umfassendes Curriculum entwickelt."

text: "The topics ”Big Data”, “Artificial Intelligence” and “Data Science” are controversially
discussed among the general public, but they present new challenges for training
in IT and IT-related professions. These challenges will become more important
in the future as a result of further social and technological development towards
a data society.\r\nAt this point, the question arises as to which aspects of this
large complex of topics are important for school and education, and how these
topics can be integrated in a meaningful and profitable way into informatics education
in vocational education. In 2017, we organized a symposium towards the topic “Data
Science” and discussed relevant aspects for general and vocational education.
Algorithms of artificial intelligence and their application in industry and society,
explorations of Big Data as well as the handling of one's own data in social networks
were worked out as core elements for teaching. For this reason, our aim is to
develop a comprehensive curriculum on this topic from these subject areas and
to develop and test modules for various teaching scenarios in order to enable
teachers from computer science, mathematics or technology to teach these topics
themselves.\r\nFor this purpose, an experimental project course was developed
within the framework of the ProDaBi project (Project Data Science and Big Data
at School, https://www.prodabi.de), which we conducted with students from upper
secondary classes at the University of Paderborn in the school year 2018/19. In
this course we try to address all these aspects. This course consists of several
modules: One module has been designed to teach the exploration of Big Data. Another
module encompasses aspects of machine learning as part of artificial intelligence.
The course concludes in a project phase which, in cooperation with local companies,
will enable the students to apply what they have learned into a real Data Science
project. Based on the experiences of this project course and the parallel testing
of individual modules with vocational schools, we will further develop the material
and make it available to other cooperation partners for testing, so that not only
complete teaching materials but also a comprehensive curriculum will have been
developed until the end of the project."

text: This investigation concentrates on value similarity between parents and their
children during adulthood. The interplay between gender, age, relationship quality,
and frequency of contact on value similarity was analyzed. A total of 600 adult
German children (53.8% women) and their parents took part in a questionnaire study.
Value orientation was measured with a short version of Schwartz’s Portrait Values
Questionnaire, and relationship quality with the Network of Relationships Inventory
(Furman & Buhrmeister, 1992).Value similarity was higher in mother–daughter
dyads compared to mother–son dyads, but in the other dyads, no significant differences
were found. Regarding relationship quality, verbal intimacy was not related to
value similarity. Parental satisfaction was associated with value similarity in
the father–child dyads. Satisfaction, as perceived by adult children, was linked
to value similarity in mother–child and father–son dyads. Furthermore, the frequency
of contact related to value similarity between mothers and sons.

text: 'The proportion of freshmen enrolled in dual study programmes has steadily
increased in recent years. From the perspective of potential students, these programmes
are highly attractive because they combine types of learning that used to be largely
separate at an institutional level: vocational and academic learning. In training-integrated
dual study programmes, different institutional contexts, governance regimes, teaching
styles and learning environments make bridging these two worlds of learning a
challenge for both educators and learners. However, these programmes also allow
leeway for didactic innovation, through the cooperation of different types of
educational institutions and through new ways of using available didactic methods,
and for establishing a new relationship between higher education (HE) and vocational
education and training (VET). This paper positions training-integrated dual study
programmes as an object of design-based research (DBR). By developing and using
an extended model for the pedagogic development of HEIs, “pädagogische Hochschulentwicklung”
(Brahm, Jenert, & Euler, 2016a, p. 19; Euler, 2013, p. 360), the paper systematically
identifies generic educational problems in these hybrids. Based on a literature
review, this paper classifies and explains the design challenges at the level
of the learning environment, the study programme and the organisation. The challenges
revolve mainly around the cooperation and integration of HE and VET. The paper
concludes with an outlook on future DBR projects designing dual studies.'

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.

text: In the mentoring programme project “Schule für alle” (“School for all”) at
the University of Bielefeld in North Rhine-Westphalia, university students of
primary or special education support a child who is in a situation of crisis for
more than one year. In addition, the university students receive ongoing, systematic
university support (cf. Kottmann, 2007, p. 32; Kottmann, 2014, p. 380).The
accompanying research by “Schule für alle” focuses on the professionalization
processes of student teachers during practical phases at universities; accordingly,
control groups were included on a pro rata basis. In the pre-post design, all
students completed a questionnaire (cf. Pieper, Kottmann & Miller, 2018, p.
294), the evaluation of which shows few changes in the professional perception
of competence. Students of the mentoring programme also regularly reflected on
their practical experience. Based on the objective hermeneutics it was discovered
that the conception of the project supports the process of perceiving, acknowledging
and becoming more sensitive in regard to heterogeneous realities in life (cf.
Pieper & Kottmann 2019b, p. 312) and that students can consciously perceive
and reflect their own normative expectations (cf. Pieper & Kottmann 2019a,
p. 79).The article primarily presents the results of the pre-post
survey in detail and adds insights into the qualitative evaluation processes.
In the conclusion, the potential of the project and mentoring programmes in general,
specifically for teacher training students, is described.

text: AbstractFluoride ion batteries (FIBs) are
a recent alternative all-solid-state battery technology. However, the FIB systems
proposed so far suffer from poor cycling performance. In this work, we report
La2NiO4.13 with a Ruddlesden-Popper
type structure as an intercalation-based active cathode material in all solid-state
FIB with excellent cycling performance. The critical charging conditions to maintain
the conductivity of the cell were determined, which seems to be a major obstacle
towards improving the cycling stability of FIBs. For optimized operating conditions,
a cycle life of about 60 cycles and over 220 cycles for critical cut-off capacities
of 50 mAh/g and 30 mAh/g, respectively, could be achieved, with average Coulombic
efficiencies between 95 – 99%. Cycling of the cell is a result of fluorination/de-fluorination
into and from the La2NiO4+d cathode,
and it is revealed that La2NiO4.13 is
a multivalent electrode material. Our findings suggest that La2NiO4.13
is a promising high energy cathode for FIBs.

text: Refill friction stir spot welding (RFSSW) is a highly flexible and promising
solid-state joining method for aluminium alloys. Alternatively, resistance spot
welding (RSW) can be stated as an appropriate joining method which can be automated
and used within a high-volume production due to short process times. Both processes
do not need any additional elements and a flat surface on both sides of the joints
can be realised. In order to meet the modern requirements for crash safety and
structural stiffness, thermal and mechanical joining methods are mainly combined
by using single-component epoxy resin adhesives. Due to an insufficient knowledge
about the application of both thermal joining methods for the abovementioned material
combinations combined with additional adhesives, deeper investigations were done
regarding the interactions of the polymers and the joining processes. Starting
with a brief presentation of the boundary conditions of the investigations and
the refill friction stir spot welding and resistance spot welding of high-strength
aluminium alloys with sheet thicknesses bigger than 5.8 mm, the paper introduces
the process-related joint properties of friction-based and resistance-based welded
joints. Afterwards, the paper discusses the influences of the process parameter
on the metallographic joint formation and load-bearing capacities for a selected
two-sheet and four-sheet material combination. When combining the spot welding
technologies with adhesives, the process parameters of the RFSSW process have
to be adapted for the two-sheet combination by adding a squeeze-out step, while
for RSW, just the preholding time has to be increased. Different challenges for
both joining methods are shown. For RFSSW, the gap formation has to be considered
when welding big total sheet thicknesses, while for RSW, the shape of the weld
nugget is more important for an appropriate joint performance. Additionally, process
optimisations for less adhesive incineration will be discussed for both joining
processes, and the influences of the adhesive on the joint formation will be addressed
with the help of load-bearing capacity evaluations. The paper closes with specific
recommendations for the realisation of refill friction stir and resistance spot-welded
joints with and without adhesive in the field of Al joints with big total sheet
thicknesses which meet the quality demands and an outlook for further research
steps will be given.

text: Monitoring systems for machines, plants, materials and equipment are increasingly
used in production processes. These online condition monitoring systems can detect
damage or excessive loads at an early stage and can drastically reduce or prevent
long downtimes of plants and machines as well as high repair and maintenance costs.
This paper depicts a method for online crack detection with pattern recognition
methods for specimens joined by self-pierce riveting under cyclic load in fatigue
tests (laboratory application). A software specially conceived for this application
was developed. This software, AnrissMF, uses active acoustic testing with a structure-borne
sensor to detect cracks in the joints at a very early stage. It is shown in this
paper that this software can detect cracks much earlier than classical failure
criteria for joints (i. e. before any drop in stiffness or frequency is observed).
Furthermore, the successful application of software AnrissMF for online crack
detection during the fatigue strength test is presented.
