@article{36701, abstract = {{Nowadays, mobility and transience are no longer exclusively associated with the marginalized and socially excluded, such as homeless or displaced people. On the contrary, mobility and transience have become a constitutive pattern of the highly skilled postmodern workforce. Yet, how mobile professionals negotiate the meaning of their homes in ‘liquid times’ and what homemaking practices they use to deal with the temporal uncertainty of their homes are questions that still require further research. This article – based on ethnographic research on German and American managers conducted in China, Germany and the United States between 2011 and 2014 – contributes to this research question by examining how mobile professionals make sense of the transience of their current homes and how transience is reflected in their homemaking practices. The article argues that for mobile professionals the home becomes a critical place not only because of new multilocal spatialities but also because of new transient temporalities. Due to the corporate practice of giving successive temporary contracts, the mobile managers’ everyday life is characterized by a ‘permanent provisionality’, that is, an incongruence of the initially imagined and the actual time horizons of their mobility.

In most German Länder, 8th graders must participate in a two‐day assessment center which combines psychometric testing with observations of their social and professional competencies in pre‐specified tasks. The programmatic aim of these assessments is to “introduce pupils early to choosing a job” (Bundesministerium für Bildung und Forschung [BMBF], 2017, p. 2) as well as to enhance the propensity of pupils to “take responsibility for their own future” (BMBF, 2017, p. 9). In the context of the German school‐to‐work system, the introduction of these new forms of diagnostics bear witness to a new preventive political rationality that aims at reducing the entry age into upper secondary education, reduce the recourse to so‐called “transition measures” and optimizing transitions into an apprenticeship market that is characterized by structural inequalities and “mismatch” between pupils’ job aspirations and the offers in apprenticeship places. However, little is known on the role of competency testing devices for the construction of further trajectories and aspirations and their role in the reproduction of inequalities in transitions from school to work. Based on an in‐depth analysis of policy documents and competency profiles (the documents handed out to the pupils after undergoing testing), the article reconstructs the political rationale for the introduction of the so‐called <em>Potenzialanalysen</em>. Based on a Foucauldian framework, we show how pupils are constructed as “competent” subjects. We show that competency assessments are part and parcel of a political rationality that aims at the promotion of a specific (future‐oriented, optimized, self‐regulated) relation to one’s own biographical future on the side of the pupils. Our results demonstrate that competency profiles construct the process of choosing a job as an individualized project of the self and that they invisibilize structural barriers and power relations. In doing so, competency assessments potentially contribute to the reproduction of inequalities in post‐secondary education through delegating “cooling out” processes from institutional gatekeepers to the interiority of persons.}}, author = {{Dahmen, Stephan}}, issn = {{2183-2803}}, journal = {{Social Inclusion}}, keywords = {{Sociology and Political Science, Social Psychology}}, number = {{3}}, pages = {{347--360}}, publisher = {{Cogitatio}}, title = {{{Constructing the “Competent” Pupil: Optimizing Human Futures Through Testing?}}}, doi = {{10.17645/si.v9i3.4354}}, volume = {{9}}, year = {{2021}}, } @article{37289, author = {{Graefe, Grit and Temmen, Katrin}}, journal = {{Bildung und Beruf, Zeitschrift des Bundesverbandes der Lehrkräfte für Berufsbildung e.V.}}, number = {{02/2021}}, pages = {{46--54}}, publisher = {{DBB Verlag}}, title = {{{Rekrutierungspotenzial für das Lehramt gewerblich-technischer Fachrichtungen aus dem Beruflichen Gymnasium mit Schwerpunkt Technik?}}}, year = {{2021}}, } @phdthesis{37396, author = {{Fiedler, Moritz}}, publisher = {{Dr. Kovac}}, title = {{{Development of a Strategic Controlling Concept}}}, year = {{2021}}, } @article{37404, author = {{Menzefricke, Jörn Steffen and Wiederkehr, Ingrid and Koldewey, Christian and Dumitrescu, Roman}}, issn = {{2212-8271}}, journal = {{Procedia CIRP}}, keywords = {{General Medicine}}, pages = {{241--246}}, publisher = {{Elsevier BV}}, title = {{{Maturity-based Development of Strategic Thrusts for Socio-technical Risks}}}, doi = {{10.1016/j.procir.2021.11.041}}, volume = {{104}}, year = {{2021}}, } @techreport{37136, abstract = {{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.

Embedding (repeated) assessment into daily teaching routine is often challenging for teachers in terms of time and organization. The use of digital tools can help teachers in the assessment process (in preparation, evaluation, documentation, etc.). A digital assessment tool (Graz Reading Comprehension test: GraLeV), focusing on assessing reading comprehension skills in Grades 3 and 4 is currently being developed in Austria. This reading assessment covers reading comprehension at the word, sentence, and text level. Text level is assessed via two subtests (Subtest I: presentation of nonsense-stories and corresponding questions, and Subtest II: maze selection). The other levels consist of one subtest each. This paper focusses on the subtests at text level. More specifically, the paper reports the results of two studies. Study 1 describes the development phases and the first piloting of these two subtests (data collection: 10/2019-12/2019). Testing 273 students with preliminary versions of the subtests (Subtest I: 30 items, Subtest II: 60 items) produced information on (a) item difficulty, (b) item discriminatory power, and (c) time limits for future speed testing. Items not meeting the required quality criteria were excluded. The final version of Subtest I consists of 16 questions referring to eight different, short, nonsense-texts. Its testing time (without instructions) is three minutes. The final version of the Subtest II consists of 2 texts each with 15 maze selections (30 items) and testing time is 100 seconds. The internal consistency is found to be good for Subtest I (α=.87) and Subtest II (α=.78 to .80). Study 2 reports on testing for validity and retest-reliability (data collection: 09/2020-11/2020). Student scores in another reading comprehension test, together with teacher assessments of reading comprehension, were used to assess congruent validity. Divergent validity was assessed using teacher assessments of mathematical and socio-emotional skills. As expected, the correlations with the congruent measures were higher than those with the divergent measures. A subsample was tested twice with the GraLeV. Retest-reliability was acceptable for Subtest II. However, the scores obtained at time 2 were higher compared to those at time 1 in both subtests. This is probably the result of increased student familiarity with the digital device and the digital test environment at time 2. The results are discussed in the light of teachers’ needs for standardized digital assessments in order to facilitate the tailoring of student reading support.  }}, author = {{Seifert, Susanne and Paleczek, Lisa}}, issn = {{1479-4403}}, journal = {{Electronic Journal of e-Learning}}, keywords = {{Computer Science Applications, Education}}, number = {{5}}, pages = {{pp336--348}}, publisher = {{Academic Conferences International Ltd}}, title = {{{Digitally Assessing Text Comprehension in Grades 3-4: Test Development and Validation}}}, doi = {{10.34190/ejel.19.5.2467}}, volume = {{19}}, year = {{2021}}, } @article{37443, abstract = {{AbstractThe range of teaching materials now available is becoming increasingly diverse. Despite this, however, the use and influence of textbooks in teaching still remains very high. When instructing reading comprehension, teachers often use textbooks as the basis for teaching in language lessons. Establishing a good match between textbooks and the skills to be acquired is therefore essential. In this paper, I investigate whether textbooks used in Austrian schools can adequately support the teaching of reading comprehension skills. Since reading comprehension is the basis for acquiring knowledge in all subjects, science textbooks are examined in addition to (German) language lesson textbooks. Thus, the content pages of four language textbooks and four science textbooks for fourth and sixth grade were analysed in terms of five different categories, i.e. general structural setup, learning goals, text types, text structures, and activities. The results reveal clear variations with respect to learning goals in language textbooks. For example, the extent to which reading comprehension is addressed ranges from 13.64 to 69.70%, depending on the book used. Although not addressed as a learning goal in the science textbooks, reading comprehension is often presupposed, especially in sixth grade. While the instruction of reading comprehension ought to entail coverage of reading strategies, this is often neglected, or only dealt with indirectly. Given the diversity of textbooks analysed, it seems all the more important to stress that teachers should: 1) clarify the goals and teaching strategies of a book before using it, 2) become aware of strategies that support the development of students' reading comprehension, and 3) use textbooks as a complementary (and not sole) tool to support reading comprehension in all subjects.}}, author = {{Seifert, Susanne}}, issn = {{2211-1662}}, journal = {{Technology, Knowledge and Learning}}, keywords = {{Computer Science Applications, Human-Computer Interaction, Education, Mathematics (miscellaneous)}}, number = {{2}}, pages = {{383--405}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Is Reading Comprehension Taken for Granted?

The questionnaire was piloted and subsequently completed by 2792 teachers across different European countries. Eleven countries provided sufficient data for analyses. Results from structural equation modelling showed that teachers’ attitudes could be reliably measured across Europe with the use of carefully devised questionnaire, whose loading and factor structure remained invariant across countries. Teachers’ views about multilingualism were most challenged by the numbers of children in their classes, not the percentage of multilingual pupils in the class. Countries differed in how they perceived multilingualism, with their differences leading to distinctive country clusters. Gender and education level (elementary vs. secondary) differences were also observed irrespective of country.

Als weitere Möglichkeit zur Problemlösung wird eine in den Prozessablauf integrierte Qualitätskontrolle gesehen, weshalb in dieser Arbeit ebenso die Eignung bekannter zerstörungsfreier Prüfmethoden für die präventive Fehlererkennung überprüft und ein zweistufiges Prüfkonzept erarbeitet wird. Das Aufzeigen möglicher Handlungsalternativen sowie die kostentechnische Gegenüberstellung der verschiedenen Anbauvarianten runden die Arbeit ab.}}, author = {{Huber, Johannes}}, isbn = {{978-3-8440-8222-7}}, keywords = {{Sheet Moulding Compounds, SMC, Online-Lackierung}}, pages = {{194}}, publisher = {{Shaker Verlag}}, title = {{{Beitrag zur Reduzierung der Fehlerhäufigkeit bei der Online-Lackierung von SMC-Außenhautbauteilen}}}, volume = {{2021,50}}, year = {{2021}}, } @phdthesis{37584, abstract = {{Im Rahmen dieser Arbeit wurde ein neuartiger Achsträger in hybrider Bauweise entwickelt und untersucht. Dieser besteht aus einer metallischen Oberschalenstruktur und einer mit Rippen ausgeformten glasfaserverstärkten thermoplastischen Unterschale (GMT), welche zur Einstellung der optimalen Steifigkeit dient. Die Rippen und Unterschale werden hierzu in einem Fließpressverfahren entweder gemeinsam als ein Bauteil oder als separate Einzelteile hergestellt. Durch den lokalen Einsatz von Faserverbundwerkstoffen in der Unterschale und der Rippenstruktur wird ein signifikanter Gewichtsvorteil gegenüber einer Referenzstruktur aus Stahl erzielt. Durch die Verwendung des GMT-Unterbodenschutzes konnten zudem die akustischen Eigenschaften des Fahrwerks hinsichtlich der Dämpfung positiv beeinflusst werden. Die hohen Anforderungen bzgl. Steifigkeit, Festigkeit und Beständigkeit der sicherheitsrelevanten Fahrwerkskomponente konnten unter Einhaltung des Bauraums erfüllt werden. Gleichzeitig konnte das Gesamtgewicht der Komponente im Vergleich zur klassischen Referenzstruktur um 30 % reduziert werden. }}, author = {{Pöhler, Simon}}, isbn = {{978-3-8440-8210-4}}, keywords = {{hybrider Achsträger, Leichtbau, Hybridsysteme}}, pages = {{124}}, publisher = {{Shaker Verlag}}, title = {{{Konzeptionierung und Auslegung eines Vorderachsträgers in hybrider Leichtbauweise im C-Segment}}}, volume = {{2021,49}}, year = {{2021}}, } @inbook{35713, author = {{Kirsch, Alexander and Blumberg, Eva and Hellmich, Frank and Hoya, Fabian Karl}}, booktitle = {{Theorie und Praxis in der Lehrerbildung.
