Design Sprints: A New Tool for Social Entrepreneurship Education
Authors: Volk-Schor Carina , Wild Antje 
Published: May 2023

AbstractThe subject of social entrepreneurship has considerably gained traction in recent years. There is significant debate about the optimal teaching concepts for this subject, providing sufficient structure to students, supporting collaborative group work, and encouraging the students to follow up their respective projects after the course or even after graduation.This study analyzes how the method “design sprint” can positively impact social entrepreneurship education. Design sprints combine several design thinking and lean start-up practices into a structured multiday format. For this study the authors created a university course in the field of social entrepreneurship. To evaluate the impact of the course, a variety of qualitative data sources was collected, ranging from learning diaries to surveys, interviews, and observations. Results indicate that design sprints provide much-needed structure to students, especially if supported by the right digital tools. They also support collaborative group work by reducing free-riding behavior and providing valuable practical skills to students.

Entrepreneurship Education and Political Change: An Exploratory Study
Authors: Walmsley Andreas , Wraae Birgitte 
Published: May 2023

AbstractThis study explores the extent to which entrepreneurship education (EE) impacts individual political attributes at the level of the individual student. The rationale here is EE’s alignment with an emancipatory principle that can also be found in Critical Pedagogy (CP). This emancipatory principle resonates with the individual recognizing their place within a socioeconomic system and subsequently seeking to change the system; i.e., they become politically engaged. Drawing on a sample of entrepreneurship students in Denmark, scores on a range of political measures were compared at the start and at the end of a semester in which students engaged in entrepreneurship education. The political measures comprised “political interest,” “political orientation,” “civic engagement,” and “sociopolitical control.” Overall, results indicate a shift toward more politically interested and engaged students. This exploratory study sets the scene for more research in this area that seeks to understand the potential inherent in EE for political change.
Re-evaluating Entrepreneurship Education Through a Team-Based Approach: Activities and Archetypes Within a Scottish University
Authors: Crammond Robert , Omeihe Ibiyemi , Murray Alan 
Published: May 2023

AbstractA university’s overall enterprising strategy, which includes identifying key stakeholders and teaching teams, promotes Entrepreneurship Education (EE) and encourages desired behaviours such as creativity, problem-solving, and both market and risk awareness. Specifically within the classroom environment, EE is strengthened by a variety of formative or summative methods, exercises, and positive cultures. However, there is a lack of a clear conceptualisation of the team-based approach comprising EE academics.Therefore, this chapter examines the enterprising activities and typical archetypal individuals and standards through an exploratory mixed-method study involving four selected undergraduate courses within a Scottish University. These activities and archetypes include prescriptive courses offered, surrounding enterprising opportunities for students, and influential individuals and processes. Qualitative student feedback is reviewed from across these four courses, and utilising a quantitative survey method, 136 students and staff responded from a sample of over 250 concerning themes of the embedding of enterprise in university, teaching methods, and networking with external partners.Findings indicate a remarkable, positive reaction to course structure and delivery, the support given from the new team-based approach, and voiced a need for EE to be universal across programmes involving experienced educators and entrepreneurs. However, results display an uncertainty concerning available networking opportunities during the entrepreneurial journey.This results in the chapter’s Team-Based Re-Evaluation Model for EE. The model encourages systematic change towards a university’s pedagogical and experiential-based EE offering, originating from enterprising academic teams. Additionally, it heightens the significance of educator personality and experience and embedding progressive, industry-relevant practices within the university context.
Coaching Concept to Improve the Sustainability Impact of Students’ Startup Ideas in an Early Stage
Authors: Preiss Philipp , Puteanus-Birkenbach Katja , Lang-Koetz Claus 
Published: May 2023

AbstractAs part of entrepreneurship education, since 2018 the “Startup Summer Camp” with a focus on “Sustainable Innovation” is offered at Pforzheim University. This Startup Summer Camp is designed to enable students to develop a sustainable oriented business model within 6 days. Hence, lectures and impulses on the goals of sustainable development are given. Methods for sustainability impact assessment are taught and the students are then guided through applying them on a specific innovation idea. These elements are part of the coaching concept developed.This chapter describes the coaching concept and presents the results of a survey regarding the effectiveness of coaching on sustainability aspects. Therefore, the following two research questions are to be answered within this study:

How aware are the students of sustainability issues and can their level of knowledge regarding sustainability topics be increased with the coaching?

Are the students able to design their startup idea in a more sustainable way and/or estimate the level of the impact on sustainability?

The results of the survey show that within a very compact coaching session, an important and applicable understanding of the complexity and urgency of sustainable development can be created and applied to an innovation idea.
Resurgence in complex Chern-Simons theory at generic levels
Authors: Duan Zhihao , Gu Jie 
Published: May 2023

Abstract
In this note we study the resurgent structure of sl(2, ℂ) Chern-Simons state integral model on knot complements S3\41, S3\52 with generic discrete level k ≥ 1 and with small boundary holonomy deformation. The coefficients of the saddle point expansions are in the trace field of the knot extended by the holonomy parameter. Despite increasing complication of the asymptotic series as the level k increases, the resurgent structure of the asymptotic series is universal: both the distribution of Borel plane singularities and the associated Stokes constants are independent of the level k.
Aspects of the electroweak Skyrmion

Published: May 2023

Abstract
We consider certain aspects of the electroweak Skyrmion (EWS). We discuss the case of EWS with dynamical Higgs and find numerical solutions for various values of the cutoff scale. Our results are qualitatively similar to the ones present in the literature, but we find a considerable lower mass than previous studies. We discuss the quantization of the light degrees of freedom and prove that the EWS is a boson. We consider the interaction between fermions and the EWS and the transfer of fermionic charge onto the soliton. We consider the large distance structure of the soliton and the interaction between two well separated EWSs. We find that the classical EWS has a magnetic dipole moment. We discuss the lifetime of the metastable soliton. Finally, we discuss some phenomenological and cosmological consequences of our results.

Authors: Loske Gunnar 
Published: May 2023

ZusammenfassungSekundär heilende operative Wunden lassen sich mit der Unterdrucktherapie behandeln. Aufgrund der teilweise starken Adhärenz des in die Wunde eingelegten Polyurethanschaumes können Verbandwechsel schmerzhaft sein. Nach der Konditionierung und Débridement des Wundgrundes kann der sekundäre Wundverschluss operativ mit einer chirurgischen Naht erfolgen. Die kutane Unterdrucktherapie wird auch präventiv nach primärer chirurgischer Naht angewendet. Beschreibungen für sekundäre Wundverschlüsse ohne eine chirurgische Naht sind bislang nicht bekannt. Die Fertigung und Handhabung eines innovativen transparenten Verbandes für die kutane Anwendung der Unterdrucktherapie werden demonstriert. Die Verbandanordnung besteht aus einer transparenten Drainagefolie und einer transparenten Okklusionsfolie. Über eine Schlauchverbindung wird mit einer Unterdruckpumpe ein Unterdruck angelegt. Anhand eines Fallbeispiels wird eine neue Methode des sekundären Wundverschlusses unter Nutzung des transparenten Unterdruckverbandes vorgestellt. Der Behandlungszyklus mit einer Anleitung zur Herstellung des Verbandes wird im Video gezeigt.
Trust, understanding, and machine translation: the task of translation and the responsibility of the translator
Authors: Chen Melvin 
Published: May 2023

AbstractCould translation be fully automated? We must first acknowledge the complexity, ambiguity, and diversity of natural languages. These aspects of natural languages, when combined with a particular dilemma known as the computational dilemma, appear to imply that the machine translator faces certain obstacles that a human translator has already managed to overcome. At the same time, science has not yet solved the problem of how human brains process natural languages and how human beings come to acquire natural language understanding. We will then distinguish between the task of translation and the responsibility of the translator. Thereafter, we will conduct a survey of the methods of machine translation (viz. RBMT, SMT, NMT, foundation models or large language models). These methods will then be critically evaluated both in general and relative to Bar-Hillel’s hypothesis about the impossibility of fully automatic, high-quality machine translation (Fahqmt). Some concluding remarks will be made about the scope, prospects, and limits of machine translation.
Lebensmittelmarkt im Wandel

Published: May 2023

ZusammenfassungBesonders in urbanen Ballungsgebieten konnten Online-Lebensmitteleinzelhändler in den vergangenen Jahren Marktanteile hinzugewinnen. Auch in der Großstadt Köln drängen verstärkt Anbieter mit online- und lieferbasierten Geschäftsmodellen auf den Markt des Lebensmitteleinzelhandels. Vor allem Betriebsformen, die ihre Produkte nur mit digitalen Plattformen anbieten und das Sortiment per eigener Lieferflotte vertreiben, haben das Potenzial, Einkaufsverhalten und Logistikketten zu verändern. Vor diesem Hintergrund ist es das Ziel dieses Beitrags, die Unterformen des reinen E‑Commerce innerhalb des Kölner Stadtgebiets zu charakterisieren, zu verorten und anhand der räumlichen Verteilung Rückschlüsse auf die zugrunde liegenden Standortanforderungen zu ziehen. Die Ergebnisse zeigen unter anderem, dass die primären Standortanforderungen der Unternehmen des klassischen E‑Commerce eine gute Verkehrsanbindung sowie eine ausreichende Flächenverfügbarkeit sind. Dem gegenüber stehen Unternehmen des sog. Quick-Commerce, welche die Nähe zu Verkehrswegen durch die Nähe zu Kund*innen substituieren. Dementsprechend liegen die Standorte des Quick-Commerce in zentralen Lagen, die in den Flächennutzungsplänen zumeist als Wohngebiet ausgewiesen sind. Dieser Beitrag bildet eine Basis zur Erklärung der Standortanforderungen dieser neuen Distributionsform.
Malicious uses of blockchains by malware: from the analysis to Smart-Zephyrus

Published: May 2023

AbstractThe permanent availability and relative obscurity of blockchains is the perfect ground for using them for malicious purposes. However, the use of blockchains by malwares has not been characterized yet. This paper analyses the current state of the art in this area. One of the lessons learned is that covert communications for malware have received little attention. To foster further defence-oriented research, a novel mechanism (dubbed Smart-Zephyrus) is built leveraging smart contracts written in Solidity. Our results show that it is possible to hide 4 Kb of secret in 41 s. While being expensive (around USD 1.82 per bit), the provided stealthiness might be worth the price for attackers.
Sustainable bacterial cellulose production by low cost feedstock: evaluation of apple and tea by-products as alternative sources of nutrients

AbstractThe high applicability of Bacterial Cellulose (BC) is often challenging due to its high production costs, which ultimately prevents its widespread use. Therefore, the present study aimed to investigate BC production using alternative feedstock to replace high-cost synthetic carbon and nitrogen sources and to evaluate the physical and structural properties of the produced BC membranes. BC was produced through a microbial consortium from kombucha, and the formulated alternative media sustained promising BC production, especially the association of apple wastes (at 10% (W/V)) with tea mixture, with a yield similar to BC produced on Hestrin–Schramm (HS) control media. Moreover, the BC samples produced in this alternative media also exhibited comparable properties to BC from HS media, with similar water-holding capacity and retention ability, thermal stability, mechanical behavior, and a crystallinity index of 87.61% and 88.08%, respectively. Thus, our findings substantiated that expensive substrates, such as glucose, peptone, and yeast extract, could be successfully replaced by apple wastes, black and green tea, for BC production while maintaining its remarkable physical and structural properties. Furthermore, besides the low-cost advantage, the bioconversion of apple waste also reduces the environmental burden caused by its disposal in landfills.

AbstractTalazoparib, a poly(ADP-ribose) polymerase inhibitor, has demonstrated efficacy in the treatment of advanced breast and prostate cancers in Western populations. This open-label, phase 1 study investigated the pharmacokinetics, safety, and antitumor activity of talazoparib monotherapy in Chinese patients with advanced solid tumors. Molecularly unselected patients (≥18 years) with advanced solid tumors resistant to standard therapy received talazoparib (oral, 1 mg once daily). Primary endpoint was characterization of single-dose and steady-state pharmacokinetics. Secondary endpoints evaluated safety, unconfirmed objective response rate (ORR), and duration of response. The safety population comprised 15 Chinese patients (median [range] age 53.0 [31.0–72.0] years). Single-dose median time to first occurrence of maximum observed concentration was 1.9 h; concentrations then declined with a mean terminal half-life (t1/2) of 67 h. Following multiple dosing, median Tmax was approximately 1.85 h with steady state generally achieved by Day 21. Treatment-related treatment-emergent adverse events (TEAEs) occurred in 86.7% (13/15) of patients (grade 3, 20.0%; grade 4, 13.3%). Two patients (13.3%) experienced serious treatment-related TEAEs. ORR (investigator-assessed) was 6.7% (95% CI: 0.2–31.9); one patient (6.7%) had a partial response. In patients with measurable disease at baseline, the ORR was 9.1% (1/11; 95% CI: 0.2–41.3; duration of response: 114 days); stable disease was achieved by 36.4% (4/11) of patients, and 54.5% (6/11) progressed by data cut-off. In Chinese patients with advanced solid tumors, the pharmacokinetic profile of talazoparib monotherapy (1 mg/day) was consistent with other patient populations. TEAEs were generally manageable with no unexpected safety findings. (ClinicalTrials.gov: NCT04635631 [prospectively registered November 19, 2020])

AbstractAdavosertib selectively inhibits Wee1, which regulates intra-S and G2/M cell-cycle checkpoints. This study investigated dosing schedules for adavosertib monotherapy, determining the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) in patients with advanced solid tumors.Patients received oral adavosertib qd or bid on a 5/9 schedule (5 days on treatment, 9 days off) in 14-day cycles, or qd on one of two 5/2 schedules (weekly, or for 2 of 3 weeks) in 21-day cycles. Safety, efficacy, and pharmacokinetic analyses were performed.Sixty-two patients (female, 64.5%; median age, 61.5 years; most common primary tumors: lung [24.2%], ovary [21.0%]) received treatment (qd schedules, n = 50; bid schedules, n = 12) for 1.8 months (median). Median time to maximum adavosertib concentration was 2.2–4.1 h; mean half-life was 5–12 h. Adverse events (AEs) caused dose reductions, interruptions and discontinuations in 17 (27.4%), 25 (40.3%) and 4 (6.5%) patients, respectively. Most common grade ≥ 3 AEs were anemia, neutropenia (each n = 9, 14.5%) and diarrhea (n = 8, 12.9%). Seven (11.3%) patients experienced 10 treatment-related serious AEs (pneumonia n = 2 [3.2%], dehydration n = 2 [3.2%], anemia n = 1 [1.6%], febrile neutropenia n = 1 [1.6%], and thrombocytopenia n = 1 [1.6%]). Overall objective response rate was 3.4% (2/58); disease control rate was 48.4% (30/62); median progression-free survival was 2.7 months.MTDs were 125 mg (bid 5/9) and 300 mg (qd 5/9 and 5/2 for 2 of 3 weeks); RP2D was 300 mg (qd 5/2 for 2 of 3 weeks). The safety profile was manageable, acceptable, and generally concordant with the known safety profile.
Work Relationships and Autonomy
Authors: Jenkins David , Neal Adam 
Published: May 2023

AbstractMany people lack autonomy because they work jobs that deny them significant and meaningful control over what they do. The negative impact of this can be ameliorated, to a degree, by the relationships that people often form with co-workers: that is, workplace sociability can itself enhance workers’ autonomy while also helping them tolerate heteronomous work by making it more bearable. In addition, workplace sociability is also a potential resource for advancing the cause of working people’s autonomy, acting as a basis for developing forms of workplace solidarity which workers can then use, through strike action and other forms of militant activity, to improve their working conditions. In this paper, we identify the tension between, on the one hand, the ameliorative andtherapeuticvalue of workplace sociability and, on the other, sociability’s potentialinstrumentalrole in expanding workers’ autonomy. We argue that developing workplace sociability into more purposive forms of solidarity involves putting at risk those other functions performed by such sociability. If expanding their autonomy is something workers have reason to care about, navigating the varied and complex functions performed by workplace sociability is thus an important dimension of workplace organizing.
Development of a method for obtaining Nyquist plots identical to those of the three-electrode AC impedance method in concrete-embedded rebar without requiring electrical continuity

Published: May 2023

AbstractCorrosion of steel bars is one cause of deterioration in reinforced concrete structures. The state of corrosion of rebar in concrete structures can be measured using the AC impedance method. The typical three-electrode AC impedance method requires electrical continuity between the rebar and the measurement device, which may be inconvenient because the structure requires to be partly damaged by processes such as drilling. The present study proposes a method to obtain the same impedance spectra as the three-electrode method by modifying the electrode configuration of the four-electrode method. The procedures for such a measurement are as follows: first, place the counter electrode and the measurement reference electrode at the measurement point; place another counter electrode at a sufficient distance from the measurement point; place another reference electrode at a sufficient distance from both the measurement point and the applied counter electrode; and connect WE_I to the applied counter electrode, WE_V to the reference electrode, CE to the applied counter electrode, and RE to the applied counter electrode, and measure the impedance. In this paper, the physical experiments and the numerical experiments demonstrate the validity of the above method. Under the conditions of this physical experiment (concrete W/C = 54.2%, cover 50 mm), the distance between the measurement point and the application counter electrode was required to be about 1.3 m. The distance between the measurement point and the reference matching electrode was also required to be about 1.3 m.

Relating chains of instrumental orchestrations to teacher decision-making
Authors: Ratnayake Iresha Gayani , Adler Jill , Thomas Mike 
Published: May 2023

AbstractThe use of digital technology has the potential to support students’ understanding in the mathematics classroom with the teacher playing a vital role. However, teaching with digital technology is not trivial, especially for teachers who are new to this. In this paper, we present an analysis of the enactment of a function lesson of a Sri Lankan mathematics teacher who used digital technology for the first time in her teaching. We combined the instrumental orchestration and ROG (resources, orientations and goals) frameworks into a conceptual framework to analyse her teaching. In particular, we used instrumental orchestration to identify how the teacher orchestrated the resources in her technology-rich classroom. This was combined with ROG theory to understand the reasons underpinning the decisions involved in moving from one orchestration to another. We demonstrate that this teacher showed diverse orchestrations and use the ROG framework to present these in the sequences in which they were used, formed into chains of orchestrations linked by goals. We propose that her didactical performance is a function of orchestration types over in-the-moment decision-making.
