A constitutive model for the determination of anchor bearing capacity based on distributed sensing in geotechnical engineering From 2015 to 2017, as part of his work as head of research and development at Stump‐Franki Spezialtiefbau GmbH, the author devoted himself to the topic of pioneering measurement methods on the basis of Distributed Strain Sensing in geotechnics. One of the first developments was and is the monitoring of grouted bodies on strand grouted anchors. The new findings at that time were presented internationally at the DFI India, 2017 as well as nationally in construction technology, 2017 and locally at the 12th Hans Lorenz Symposium in Berlin, 2016. It was shown that the measurement results of the strain measurement using distributed strain sensing can be used to check over the following years whether the grouted anchors have been overloaded. The author already pointed out at the time that correct interpretation not only requires an understanding of the measuring process used, but also a certain wealth of experience in interpreting the measurement results in the direct context of geotechnics. As part of his work on the DIN standardization committee NA 005‐05‐17 AA Grouted anchors, accompanied by his practical experience, the author has dealt in depth with the question of what exactly is actually measured in the grout body using distributed strain sensing and what conclusions can be drawn about the load‐bearing capacity of grouted anchors on the basis of the measurement results. This article is intended to describe a constituent model on the basis of which further developments are possible for the interpretation of the measurement results with regard to their use as proof of economic efficiency and anchor load‐bearing capacity.

The topic of language learners' engagement, which has enjoyed immense popularity in recent years, emerged more than 20 years ago from the explorations of individual and social variables in task performance. In the domain of second/foreign language acquisition, what has attracted much attention is the relationship between engagement and other approximate concepts, such as motivation, interest, or investment, but little is known about the connection between self‐regulation and engagement. Hence, the present study was undertaken to explore the connection between L2 learners' engagement and their self‐regulated strategy use. Semi‐structured interviews were conducted with two students, labeled by their teachers as highly engaged, and another two, described as disengaged. The results suggest that the two frameworks are interconnected but not fully analogous, with the main difference lying in the conceptualization of the role motivation. [ABSTRACT FROM AUTHOR]

Measures against overcrowding have been developed and analyzed mainly in the context of urban destinations. For rural areas near metropolitan areas, which have been strongly affected by overcrowding by day trip tourists since the two Covid-summers of 2020/21 on many weekends, there is hardly any research available on this topic. In the context of a case study for Tölzer Land, 129 strategies and measures developed for urban areas and protected areas were compiled from the literature and their applicability in rural areas was examined. A comparison with the measures already implemented and planned in the destination showed that the concepts can be mostly transferred to rural areas where they are also suitable to counteract the negative effects of overcrowding.

Long‐term crack monitoring of prestressed concrete structures by means of distributed fiber‐optic strain sensing In the ceiling area of a connecting subway tunnel in Munich, Germany, fiber‐optic sensor cables were installed for continuous long‐term crack monitoring. According to the measurement concept, continuous monitoring of the total deformations as well as several reference date measurements are planned with regard to the actual crack monitoring of the prestressed concrete construction. The aim of the measurements is the fiber‐optic crack monitoring of a pre‐damaged prestressed concrete structure from the 1970s, which was refurbished in the course of the fiber‐optic installation. The structure is exposed to high traffic loads from road traffic as well as temperature impact. The prestressed concrete structure is a single span slab construction with straight and parabolic tendons. The original ceiling had an increased potential for damage on the underside of the slab (crack pattern) as well as severe damages associated with the existing prestressing steel structure. During the renovation of the prestressed concrete slab, shotcrete with supplementary reinforcement was applied to achieve an announcement behavior in case of tendon failure. The following paper reports on the first results of crack monitoring based on continuous fiber optic measurements along the embedded fiber‐optic sensing cables. The measurements are based on the technology of distributed Brillouin sensing. [ABSTRACT FROM AUTHOR]

Small‐diameter tunneling in hard rock is increasingly widespread due to the need for new and longer utility tunnels comprising sewer, stormwater, freshwater, or hydropower as well as cable tunnels and casings for pipelines transporting gas or hydrogen. Utility tunnels have to deal with a wide range of geological settings, like small overburden, weathered rock, rock–soil transitions, as well as fractured or intact hard rock with high strength and abrasivity. A database has been created including 35 hard rock projects with diameters between 1 and 5 m as well as more than 70,000 m of tunnel alignments, with a median drive length of less than 500 m. Challenges in creating it and some early interpretations based on the contents of the database are presented. Details about an exemplary pipe jacking project in basement rocks in Brittany, France, are given. The large variety in this small‐diameter range in hard rock includes different TBM types, cutterhead designs, cutter types, and geotechnical conditions. Potential pitfalls in small‐diameter TBM data analysis are shown and general drive parameter trends and penetration prediction approaches are presented and set in relation to the geotechnical conditions. Our analysis shows that difficult ground conditions do not only incorporate rocks with very high strength, but also generally weak rocks like schist or limestone could be responsible for low penetration rates and high thrust forces.

Während der laufenden SARS-CoV-2-Pandemie hat die Forschung gezeigt, dass sozio-ökonomische Ungleichheiten eine entscheidende Rolle beim Verständnis der Ausbreitung des Virus spielen. Menschen mit einem niedrigeren sozio-ökonomischen Status haben eine höhere Wahrscheinlichkeit, sich mit COVID-19 zu infizieren und an dem Virus zu sterben. Da sozio-ökonomische Ungleichheiten eine starke räumliche Dimension haben, z. B. aufgrund zunehmender Ungleichheiten innerhalb von Städten, könnte dieses Wissen zur Erklärung und zur Vorhersage der geographischen Ausbreitung des Virus beitragen. Empirische Belege auf feiner geographischer Ebene innerhalb von Städten sind jedoch äußerst rar. Wir adressieren diese Forschungslücke und untersuchen die Beziehung zwischen SARS-CoV-2-Fällen pro 100.000 Einwohner und dem sozio-ökonomischen Status auf der Grundlage detaillierter Daten auf Stadtbezirksebene in Duisburg, Deutschland, welche vom Gesundheitsamt der Stadt Duisburg zur Verfügung gestellt wurden, sowie Daten des KECK-Atlasses. Unsere Regressionsergebnisse deuten stark auf einen negativen Zusammenhang zwischen sozio-ökonomischem Status und Morbiditätsraten für die zweite Welle der aktuellen Pandemie in Duisburg hin. Unsere Ergebnisse verbessern das Verständnis der geographischen Ausbreitung von SARS-CoV-2 in Städten und liefern politischen Entscheidungsträgern detaillierte Informationen darüber, wie geographisch sensible Maßnahmen zur Eindämmung der Pandemie konzipiert werden können, um sozio-ökonomisch benachteiligte Menschen in unserer Gesellschaft besser zu schützen. During the ongoing SARS-CoV-2 pandemic, research has shown that socio-economic inequalities play a crucial role to understand the spread of the virus. Precisely, people are more likely to get infected with COVID-19 and to die of the virus if they have a lower socio-economic status. As socio-economic inequalities have a strong spatial dimension, for example, due to rising inequalities within cities, this knowledge might help to explain and predict the geographic spread of the virus. However, empirical evidence at fine-grained geographic levels within cities is extremely scarce. We address this research gap and examine the relationship between SARS-CoV-2 cases per 100.000 inhabitants and the socio-economic status based on detailed data at the city-district level in Duisburg, Germany provided by the public health department of Duisburg as well as data by the KECK-Atlas. Our regression results strongly suggest a negative relationship between socio-economic status and morbidity rates for the second wave of the current pandemic in Duisburg. Our results improve our understanding of the geographic spread of the virus within cities and thus provides policy makers with detailed information on how to design geographically sensitive policies to fight the virus in future waves and to better secure the most vulnerable people in our society.

Im Kontext der Overtourism-Diskussion und im Zuge der fortwährenden COVID-19-Pandemie gewinnt die Perspektive der lokalen Bevölkerung im tourismuswissenschaftlichen Forschungsdiskurs immer mehr an Bedeutung. Dementsprechend sind es vorrangig die Einheimischen, die sich mit zunehmenden touristischen Überfüllungseffekten in ihren Heimatorten konfrontiert sehen. Dabei führt die unmittelbare Interaktion zwischen diesen beiden Interessengruppen vor allem in stark frequentierten Destinationen und beliebten Hotspots vielfach zu Konfliktpotenzialen unterschiedlichsten Ausmaßes. Dieser Beitrag soll die Perspektive der Einheimischen in der gegenwärtigen Overtourism-Forschung aufarbeiten und dabei vor dem Hintergrund der aktuellen Pandemiesituation, Bezug auf die diesbezüglichen Problemstellungen nehmen. Die vorliegende Fallstudie aus dem Allgäu ergänzt empirisch die themenzentrierte Betrachtung, die über die Wahrnehmung von Crowding-Effekten und Overtourism sowie die Einstellung gegenüber lokalen Besucherlenkungsmaßnahmen aus Sicht der Allgäuer Bevölkerung Auskunft geben soll. In the current overtourism research discourse and in the wake of the ongoing coronavirus pandemic, the perspective of the residents is becoming more and more important, as it is primarily the locals, who find themselves confronted with increasing overcrowding effects in their hometowns. The direct interaction between tourists and residents, especially in high frequency destinations and popular hotspots, often leads to conflict potentials of diverse magnitude. This paper aims to review the perspective of the locals in the current overtourism research discourse and refer to the related problems. The present case study from the Allgäu region empirically complements the theoretical perspective, intended to provide information about the perception of the local residents concerning crowding effects and overtourism as well as the attitude to local guidance measures and visitor management strategies.

Training programmes for counsellors and psychotherapists comprise complex combinations of different types of learning activity. However, research into the process and outcomes of therapy training has almost entirely comprised investigations of specific training elements. In addition, studies of training have not taken account of the potential influence of the social and organisational context within which training is delivered. The present paper reports on a realist analysis of learning mechanisms within a professional counsellor training programme in pluralistic-integrative counselling, drawing on multiple sources of data collected over a ten-year period. Training outcomes were oriented toward preparing trainees to be flexible and resourceful practitioners in non-medicalised community settings. Core learning mechanisms included building on pre-existing skills, knowledge and awareness, and acquiring conceptual tools appropriate to a collaborative style of working, within an immersive learning environment that supported focused reflection and engagement with personally challenging learning tasks. Implications for further research on therapist training, and programme design, are discussed. [ABSTRACT FROM AUTHOR]

Das Lernen ist ein Phänomen, das von Generation zu Generation unterschiedlich sein kann. Es ist bekannt, dass auch die Generation Z Lerncharakteristika aufweist, die sie von früheren Generationen unterscheiden. Ein großer Teil der türkischen Gesamtbevölkerung und des türkischen Schulwesens besteht aus Mitgliedern der Generation Z. Aber es sind weniger Studien zum Thema Lernstrategien der Generation Z in der Türkei zu finden. Das Ziel dieser Fallstudie ist es, die Sprachlernstrategien der Lernenden der Generation Z im Fernunterricht festzustellen. In diesem Kontext wurden Antworten auf die Fragen gesucht, wie Lernende der Generation Z eine Fremdsprache lernen und ob der fremdsprachliche Fernunterricht entsprechend den Lernstrategien dieser Generation durchgeführt wird. Ein Fragebogen mit 10 offenen Fragen wurde an die Lernenden in den Vorbereitungsklassen der Hochschule für Fremdsprachen der Trakya Universität gesendet und die Antworten von insgesamt 78 Lernenden wurden durch eine Inhaltsanalyse bewertet. Als Fazit konnte festgestellt werden, dass die Lernenden die kognitiven mehr, aber die metakognitiven und affektiven Lernstrategien kaum verwenden. Im Zusammenhang mit dieser Situation gaben die Lernenden an, dass sie Motivations- und Konzentrationsprobleme im Fernunterricht haben. Am Ende der Studie wurden Vorschläge zur Lösung dieser Probleme entwickelt. [ABSTRACT FROM AUTHOR]

I offer some ideas on what common features the therapy processes in the cases within the same category might have presented, based on some notions from qualitative process psychotherapy research. However, when entering the new therapy, she had told that she has her own ideas about the underlying causes of her illness and expressed that previous therapies have not given her answers to fundamental questions of who she is and why she got sick. For J.J., her therapist entering a training program in Pluralistic therapy introduced in some way a new start of her therapy with this therapist. When "good outcome" does not correspond to "good therapy": Reflections on discrepancies between outcome scores and patients' therapy satisfaction. [Extracted from the article]

The client was invited to identify changes that may have occurred as a consequence of therapy, along with helpful and unhelpful aspects of therapy and any relevant non-therapy factors (Elliott & Rodgers, [11]). Therapy options available to clients included a psychoeducational programme, individual therapy, and group therapy. Pluralistic practitioners draw on concepts from evidence-based therapy approaches such as psychodynamic, CBT, and experiential therapy, alongside client suggestions, with the objective of constructing a way of working that is tailored to the unique needs, preferences, and lived experience of each client.

What is meant by the term overtourism? Which dimensions, indicators and criteria are relevant to describe adequately this touristic phenomenon? At first glance, these questions may reflect a very theoretical approach, but they are nevertheless of enormous practical importance for the future of tourism, since an in-depth understanding of the concept of overtourism is essential for both theory and practice, in order to be able to confront the relevant challenges for the tourism industry. Hence, against the backdrop of socio-economic conflicts in the tension between acceptance and aversion in tourist destinations, it is necessary to investigate the multifaceted effects and impacts of overtourism on all stakeholders involved and to develop appropriate measures and recommendations for action. In the course of a descriptive-explorative approach and the presentation of a case study, this article is intended to provide more clarity about the phenomenology of overtourism and the associated research perspectives in the current discourse.

Zahlreiche Autoren, Autorinnen und kritische Initiativen (z. B. DORA) kritisieren den zu hohen und schädlichen Einfluss quantitativer Daten, welche akademische Instanzen für Evaluationszwecke heranziehen. Wegen des großen Einflusses der globalen Zitatdatenbanken von Thomson Reuters (bzw. Clarivate Analytics) auf die Bewertung der wissenschaftlichen Leistungen von Forscherinnen und Forschern habe ich extensive qualitative und quantitative Fallstudien zur Datenqualität des Social Sciences Citation Index (SSCI) durchgeführt, d. h. die Originaleinträge mit den SSCI-Datensätzen verglichen. Diese Fallstudien zeigten schwerste – nie in der Literatur erwähnte – Fehler, Verstümmelungen, Phantomautoren, Phantomwerke (Fehlerrate in der Fallstudie zu Beebe 2010, Harvard Law Review: 99 Prozent). Über die verwendeten Datenerfassungs- und Indexierungsverfahren von TR bzw. Clarivate Analytics ist nur wenig bekannt. Ein Ergebnis meiner Untersuchungen: Bei der Indexierung von Verweisen in Fußnoten (wie in den Rechtswissenschaften, gerade auch der USA, vorgeschrieben) scheinen die verwendeten Textanalyse-Anwendungen und -Algorithmen völlig überfordert. Eine Qualitätskontrolle scheint nicht stattzufinden. Damit steht der Anspruch des SSCI als einer multidisziplinären Datenbank zur Debatte. Korrekte Zitate in den Fußnoten des Originals können zu Phantom-Autoren, Phantom-Werken und Phantom-Referenzen degenerieren. Das bedeutet: Sämtliche Zeitschriften und Disziplinen, deren Zeitschriften und Büchern dieses oder ähnliche Zitierverfahren verwenden (Oxford-Style), laufen Gefahr, aufgrund starker Zitatverluste falsch, d. h. unterbewertet, zu werden. Wie viele UBOs (Unidentifiable Bibliographic Objects) sich in den Datenbanken SCI, SSCI und AHCI befinden, wäre nur mit sehr aufwändigen Prozeduren zu klären. Unabhängig davon handelt es sich, wie bei fast allen in meinen Untersuchungen gefundenen fatalen Fehlern, eindeutig um endogene Fehler in den Datenbanken, die nicht, wie oft behauptet, angeblich falsch zitierenden Autorinnen und Autoren zugeschrieben werden können, sondern erst im Laufe der Dateneingabe und -verarbeitung entstehen. Numerous authors and critical initiatives (such as DORA) criticize the excessive and damaging influence of quantitative data that academic administrators use for evaluation purposes. Due to the great impact of Thomson Reuters' (TR) or Clarivate Analytics' global citation databases on the evaluation of researchers' scientific achievements, I have conducted extensive qualitative and quantitative case studies on the data quality of the Social Sciences Citation Index (SSCI), in an innovative way by comparing the original references cited with the SSCI records indexed entries. These case studies revealed the most serious – to my knowledge, never mentioned in the literature before – errors, mutilations, phantom authors, phantom works (error rate: 99 % in the case study for Beebe 2010, Harvard Law Review). Little is known about the data collection and indexing techniques used by TR and Clarivate Analytics. A result of my investigations: When indexing references in footnotes (as prescribed in the scientific discipline of law, especially in the USA), the text analysis applications and algorithms seem to be completely overextended; quality control seems not to be in place. This raises the claim of the SSCI to be of a high quality multidisciplinary database. Correct citations in the footnotes of the original can degenerate into phantom authors, phantom works, and phantom references. This means that all journals and disciplines with journals and books using this or similar citation method (Oxford Style) run the risk of being misrepresented (i.e. undervalued) due to heavy citation losses. How many unidentifiable bibliographic objects (UBOs) are in the SCI, SSCI and AHCI databases would only be possible with very complex procedures. Either way, as with almost all the fatal errors found in my investigations, it is clearly a matter of endogenous databases errors that can not be attributed, as so often claimed, to allegedly misquoted authors, but induced only in the course of data entry and processing.
