Digitale Lehr- und Lernunterstützung an deutschen Universitäten: Anforderungen und Rahmenbedingungen für die Implementierung einer Mentoring Workbench

Deutsche Universitäten bemühen sich aufgrund überfüllter Hörsäle, heterogener Studierendengruppen (Heublein et al., 2017) und hoher Abbruchquoten (Heublein, 2014) seit Jahren um die stärkere Unterstützung der Studierenden, um so die Verbleibszahlen und den Studienerfolg zu erhöhen und Lehrende zu entlasten. Ein Ansatz für die Sicherung des Lernerfolges fokussiert die individuelle und motivierende Unterstützung und Betreuung der Studierenden (Bülow-Schramm, Merkt, & Rebenstorf, 2011). Da Lehrende jedoch ihre Studierenden häufig nicht persönlich kennen und auch keine Zeit für individuelle Beratung haben, begreifen wir im Projekt “tech4comp – Personalisierte Kompetenzentwicklung durch skalierbare Mentoringprozesse“ digital gestütztes Mentoring als Lösungsansatz. Mentoring wird im Projekt als dyadischer Prozess des akademischen Austausches von Ideen und Wissen auf Augenhöhe verstanden und umfasst sowohl die sozio-emotionale Unterstützung der Studierenden als auch die individuelle Begleitung der Kompetenzentwicklung. Um diese Art von Mentoring an Hochschulen für eine variierende Zahl an Studierenden etablieren zu können, setzt das Projekt auf die Umsetzung mittels Informations- und Kommunikationstechnik (IKT) in Form der Mentoring Workbench. Diese ermöglicht elektronisch gestütztes Mentoring (E-Mentoring). Um die derzeit an vier sächsischen Hochschulen exemplarisch erprobte Mentoring Workbench auch über die Projektlaufzeit hinaus und deutschlandweit zu implementieren, werden die dafür zu erfüllenden Anforderungen an Hochschulen aus einer Literaturanalyse zusammengetragen und daraus Empfehlungen für den Projektkontext abgeleitet

tqix.pis: A toolbox for large-scale quantum simulation platforms

We introduce tqix.pis, a library of tqix for executing various algorithms in large-scale quantum simulation platforms. The program emulates basic functions of a quantum circuit, including initialization qubits, quantum gates, and measurements. It utilizes the collective processes in ensembles of two-level systems to reduce the dimension, and facilitates the simulation time with multi-core processors and Graphics Processing Units. The library is thus programmable for different large-scale quantum simulation platforms, such as trapped ions, ultracold atoms in optical lattices, Rydberg atom arrays in optical tweezers, and nitrogen-vacancy centers. It is applicable for examining spin squeezing, variational quantum squeezing, quantum phase transition, many-body quantum dynamics, and other quantum algorithms.Comment: 17 pages, 8 figure

Topology analysis for anomalous Hall effect in the noncollinear antiferromagnetic states of Mn3AN (A=Ni, Cu, Zn, Ga, Ge, Pd, In, Sn, Ir, Pt)

We investigate topological features of electronic structures which produce large anomalous Hall effect in the non-collinear antiferromagnetic metallic states of anti-perovskite manganese nitrides by first-principles calculations. We first predict the stable magnetic structures of these compounds to be non-collinear antiferromagnetic structures characterized by either $T_{1g}$ or $T_{2g}$ irreducible representation by evaluating the total energy for all of the magnetic structures classified according to the symmetry and multipole moments. The topology analysis is next performed for the Wannier tight-binding models obtained from the first-principles band structures. Our results reveal the small Berry curvature induced through the coupling between occupied and unoccupied states with the spin-orbit coupling, which is widely spread around the Fermi surface in the Brillouin zone, dominantly contributes after the $k$-space integration to the anomalous Hall conductivity, while the local divergent Berry curvature around Weyl points has a rather small contribution to the anomalous Hall conductivity.Comment: accepted for publication in Physical Review

Impact of trained human resources, adoption of technology and international standards on the improvement of accounting and auditing activities in the agricultural sector in Viet Nam

Recently, the adoption of accounting and auditing standards in the agricultural sector has been a global phenomenon that has gained increasing trend due to the significant role of the agricultural industry in the country's economy. Thus, the present study examines the impact of trained human resources, technology adoption, and international standards on improving accounting and auditing activities in the agricultural sector in Vietnam. The present research investigates the moderating impact of agricultural, institutional support among the linkage of trained human resources, technology adoption, international standards, and improvement of accounting and auditing activities in the agricultural sector. The present article has adopted the questionnaires to gather the primary data from selected respondents. The current research has applied the smart-PLS to test the study's hypotheses. The results revealed that trained human resources, technology adoption, and international standards positively impact the improvement of accounting and auditing activities in the agricultural sector. The findings also indicated that the agricultural institutional support significantly moderates the linkage of trained human resources, technology adoption, international standards, and improved accounting and auditing activities in the agricultural sector.Nguyen Van Hoa (University of Kinh Bac (UKB)), Nguyen Thi Hanh Duyen (Vinh University), Vu Ngoc Huyen (Viet Nam National University of Agriculture (VNUA)), Hoang Vu Quang (Researcher at Institute of Policy and Strategy for Agriculture and Rural Development (IPSARD)), Nguyen Van Huong (Hung Yen University of Technology and Education (UTEHY)), Nguyen Thi Cam Tu (National Economics University (NEU)), Bui Thi Minh Nguyet (Vietnam National University of Forestry (VNUF))Includes bibliographical references

The effect of emotional intelligence on the performance of auditors

This study aims to evaluate the impact of effective emotional intelligence on the work of auditors in Ho Chi Minh City, Ho Chi Minh. The authors conducted a survey for 355 auditors at companies and organizations operating in the field of auditing. The results show that there were 4 factors of emotional intelligence that affect job performance, arranged in the following sequence: (1) Perception of emotions, (2) Positive thinking with emotions, (3) Understand emotions, (4) Control emotions. This is the basis for the authors to give some implications to improve the emotional intelligence characteristics of auditors towards work efficiency

Risk assessment, implementation of occupational health, safety and hygiene in small and medium manufacturing enterprises: A case study in central Vietnam

This study aims to identify and evaluate the influence of the factors affecting the implementation of occupational health and safety of employees and employers and its impact on occupational health and safety and legalize risk assessment in small and medium-sized manufacturing enterprises in central Vietnam through the survey among 246 business representatives and data processing through the software SPSS 20 and AMOS 20. The results show that there are 3 factors affecting the implementation of occupational health, safety and hygiene. In order: (1) Safety regulations and instructions; (2) Occupational health, safety policy and (3) Occupational health and safety training. There is no relationship between the impacts on the implementation of occupational health and safety of the employer. In addition, a very interesting finding about the relationship of factors implementing occupational health and safety of employers was a positive influence on the legalization of risk assessment activities. On the basis of these results, employees, business owners and state management agencies will have grounds to offer useful solutions in risk assessment in order to better perform safety work and occupational health

Unexpected cases in field diagnosis of African swine fever virus in Vietnam: The needs consideration when performing molecular diagnostic tests

Background: The first confirmed case of African swine fever (ASF) in Vietnam was reported officially in February 2019. To date, ASF virus (ASFV) have been detected in 63/63 provinces in Vietnam. Currently, real-time polymerase chain reaction (PCR) is considered to be a powerful tool for viral detection in field samples, including ASFV. However, some recent reports have suggested that mismatches in primer and probe binding regions may directly affect real-time PCR qualification, leading a false-negative result.Aim: This study aims to further examine a conflicting result obtained from two OIE recommended methods, conventional PCR and real-time PCR, for ASFV detection.Methods: Two ASF suspected pigs from different provinces in the north of Vietnam were selected for this study based on clinical signs and postmortem lesions. The different results obtained by OIE-recommended conventional PCR and real-time PCR were further analyzed by the Sanger sequencing method and virus isolation in combination with hemadsorption (HAD) test using porcine alveolar macrophages cells.Results: The results showed that when the primer sequence matched perfectly with the sequences of field isolates, a mutation in probe binding region was found, indicating that a single mismatch in the probe binding site may cause a false-negative result by real-time PCR in detecting ASFV in clinical samples in Vietnam. An agreement between conventional PCR, using PPA1/PPA2 primers and two golden standard methods, virus isolation in combination with HAD assay, and sequencing method was observed in this study.Conclusion: A single mismatch in the probe binding site caused a failse-negative result by realtime PCR method in field diagnosis of ASFV. The needs consideration when selecting the appropriate molecular diagnostic methods is based on the current databases of ASFV sequences,  particularly for epidemiological surveillance of ASF.
