Von der Allgemeinen Erziehungswissenschaft zur Empirischen Bildungsforschung?
Authors: Westphal Andrea , Zawacki-Richter Olaf 
Published: March 2021

ZusammenfassungDer vorliegende Beitrag beschäftigt sich mit den Publikationen, die in der Zeitschrift für Erziehungswissenschaft (ZfE) in den Jahren 1998–2017 veröffentlicht wurden. Angesichts der Veränderungen in der erziehungswissenschaftlichen Forschungslandschaft in der jüngeren Vergangenheit untersuchen wir, inwiefern sich eine veränderte Schwerpunktsetzung auch in den Beiträgen der ZfE nachweisen lassen. Dazu führen wir zunächst eine quantitative Textanalyse durch und identifizieren die häufigsten sowie die charakteristischen Bigramme (Zweiwortsequenzen) in vier aufeinanderfolgenden Fünfjahres-Abschnitten (1998–2002, 2003–2007, 2008–2012, 2013–2017). Zudem prüfen wir, inwiefern bestimmte Wortstämme (bspw. „erziehungswissenschaft“, „bildungsforsch“, „didakt“) über die Jahre hinweg häufiger auftreten. Schließlich erstellen wir mit dem Textmining Tool Leximancer™ concept maps, die Hinweise auf die semantische Struktur der Themengebiete und Schlüsselkonzepte geben. Die Ergebnisse deuten darauf hin, dass im gesamten Zeitraum mehrheitlich Beiträge mit empirischem Fokus publiziert wurden, ein inhaltlicher Fokus auf sozialen Aspekten von Bildung lag und die Beschäftigung mit der allgemeinen Erziehungswissenschaft abnahm.
Rape myth acceptance as a relevant psychological construct in a gender-unequal context: The Hungarian adaptation of the updated Illinois rape myths acceptance scale
Authors: Nyúl Boglárka , Kende Anna 
Published: March 2021

AbstractThe Updated Illinois Rape Myth Acceptance Scale (UIRMAS) has been widely used for measuring rape myth acceptance. The scale was created in the United States, however studies have shown that rape myth is a culturally and socially embedded phenomenon. Therefore, in order to measure rape myth acceptance in other parts of the world, the scale needs to be validated. Victim blaming and rape myths are both widespread in public reactions to rape in Hungary (i.e., in media reports and public opinion). Furthermore, Hungary can be characterized by a weak feminist movement and scoring low on gender equality measures. Nevertheless, we expected and found the reliability and validity of the Hungarian version of the Updated Illinois Rape myth acceptance Scale (UIRMAS). In Study 1 we conducted a confirmative factor analysis to assess the structural validity of the scale and identified the original factors of UIRMAS on a large convenience sample (N = 758, 25.4% men 74.6% women). In line with previous empirical evidence we also found that men, people with stronger just-world beliefs and higher sexism accepted rape myths more. In Study 2 we again found support for the original factor structure and construct validity of UIRMAS on a nationally representative sample (N = 1007, 49.2% men 50.8% women), and also tested its convergent and discriminant validity. The results suggest that UIRMAS is a valid and reliable scale in the Hungarian context that can, for example, be used for measuring impact assessment of interventions.
New Advances in Biostratigraphy of the Lower/Middle Norian Transition: Conodonts of the Dovško Section, Slovenia

Published: March 2021

AbstractThis study presents the results of the conodont biostratigraphy and microfacies analysis carried out on the pelagic limestones of the Upper Triassic Dovško Section in Slovenia, which represents the eastern part of the Slovenian Basin. The age of the section ranges from the Lacian 1 to the Alaunian 1. The Lacian part of the succession is predominantly characterized by the representatives of the genus Ancyrogondolella. Transitional morphologies towards Alaunian faunas first appear in the Lacian 3 and become common during the Lacian-Alaunian transition. This evolutionary development coincides with a shift in microfacies from a dominantly radiolarian-bearing mudstone-wackestone-packstone to a filament- dominated wackestone-packstone, and the formation of small neptunian dykes, which may reflect environmental perturbations and/or a change in basin geometry. The proliferation of the genera Epigondolella and Mockina is observed in the Alaunian part of the section, though the genus Ancyrogondolella is still present in this interval. Systematic description of the conodont taxa is provided, and seven new species and two new subspecies are established. The new advances will be of great value in further biostratigraphic studies, especially in areas without ammonoid faunas, and in the reconstruction of the paleogeography of the Slovenian Basin.
Dealing with Multicollinearity Problem in Analysis of Side Friction Characteristics Under Urban Heterogeneous Traffic Conditions
Authors: Singh Shishodiya Ghanshyam , Kumar S. Vasantha 
Published: March 2021

AbstractDisturbance to the moving traffic, such as on-street parking and bus stop on carriageway normally called as side friction in the literature, is one of the major problems that impact the vehicular speed on urban arterials in developing countries like India. Regression model to study the mode-wise vehicular speeds using side friction and other influencing variables faces the problem of multicollinearity as there is a strong correlation between the independent variables which results in high R2 and high p values. Instead of dropping the highly correlated variables which is the conventional practice to deal with multicollinearity, we proposed an approach of taking a linear combination and ratio of independent variables. To test the applicability of the proposed approach, traffic data from five locations in Hyderabad and Vellore in India having a wide variety of geometric and traffic characteristics with one or more side frictions were collected and regression models were built. It was found that the proposed approach of taking linear combination and ratio worked very well as the models exhibited a high R2, low p values and low variance inflation factor. The regression models also forecast speeds with good and reasonable accuracy. For better understanding of the impact of side friction, the present study proposed an index called side friction index and it was found that the number of side friction elements and their impact are directly proportional. Also, the impact is not uniform across the different vehicle types. Though the present study focussed on side friction problem, the approach that we proposed in this paper to deal with multicollinearity can be applied in other fields as well.
Temporal network embedding using graph attention network
Authors: Mohan Anuraj , Pramod K V 
Published: March 2021

AbstractGraph convolutional network (GCN) has made remarkable progress in learning good representations from graph-structured data. The layer-wise propagation rule of conventional GCN is designed in such a way that the feature aggregation at each node depends on the features of the one-hop neighbouring nodes. Adding an attention layer over the GCN can allow the network to provide different importance within various one-hop neighbours. These methods can capture the properties of static network, but is not well suited to capture the temporal patterns in time-varying networks. In this work, we propose a temporal graph attention network (TempGAN), where the aim is to learn representations from continuous-time temporal network by preserving the temporal proximity between nodes of the network. First, we perform a temporal walk over the network to generate a positive pointwise mutual information matrix (PPMI) which denote the temporal correlation between the nodes. Furthermore, we design a TempGAN architecture which uses both adjacency and PPMI information to generate node embeddings from temporal network. Finally, we conduct link prediction experiments by designing a TempGAN autoencoder to evaluate the quality of the embedding generated, and the results are compared with other state-of-the-art methods.
Red-headed ash borer Neoclytus acuminatus acuminatus (Fabricius) (Coleoptera: Cerambycidae): the global distribution, current spreading and the seasonal activity depending on its different habitats
Authors: Keszthelyi Sándor 
Published: March 2021

AbstractHolarctic expansion of Neoclytus acumiantus acuminatus due to its polyphagous character has been a major concern for plant health, which raises several questions about its spreading directions. I have examined all bibliographical references, phytosanitary reports and authentic photographs from the online sources in the quest of the determination of the worldwide distribution and flight phenology of N. a. acuminatus. The expansion, including the western Palearctic regions as well as several Neotropical habitats, is proven and has become more intense in the last decades. It can be found mostly on the Holarctic region including 21 countries, which is supported by 51 publications. Its spreading mostly northward and eastward in the Palearctic is continuous due to anthropogenic effects, climate change as well as movement of infested materials. Flight phenology and population densities as a function of habitats were mapped. The detection in novel habitats of this pest due to imported wood materials and products is envisaged in the foreseeable future. The primary criterion for controlling the species adapted to the commercial trade and climatic change would be the elaboration of a monitoring system in affected and exposed areas.
11626 Impact of Preeclampsia on the Incidence of Breast Cancer in the Black Women’s Health Study
Authors: Bigham Zahna R. 
Published: March 2021

ABSTRACT IMPACT: This study will be the first to explore the relationship between preeclampsia and breast cancer risk using the largest cohort of Black women in the US, and it will guide future research and potentially inform clinical practice to reduce breast cancer disparities in this population. OBJECTIVES/GOALS: Black women are disproportionately impacted by preeclampsia. This disorder induces hormonal changes that may contribute to diseases such as breast cancer. However, there is a lack of clear data on the relationship between preeclampsia and breast cancer, and few previous studies included Black women. This study will work to fill this knowledge gap. METHODS/STUDY POPULATION: We prospectively assessed the association between preeclampsia during pregnancy and risk of breast cancer in 43,040 parous women in the Black Women’s Health Study, a nationwide cohort of Black women who were ages 21 -69 at enrollment in 1995. Through 2017, we confirmed 1,968 incident diagnoses of invasive breast cancer. Approximately 6% of parous women reported a diagnosis of preeclampsia; characteristics of the population at baseline are shown in Table 1. We used multivariable Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for risk of breast cancer overall. We used age as the time scale and adjusted for breast cancer risk factors including parity, age at first birth, age at menarche, and body mass index (BMI) at age 18. RESULTS/ANTICIPATED RESULTS: : Compared to parous women without a history of preeclampsia, women with a history of preeclampsia in any pregnancy were not at an increased risk of breast cancer overall (HR 0.98; 95% CI 0.81, 1.18). These preliminary results suggest that history of preeclampsia is not an important risk factor for breast cancer overall in Black women. Our analyses are ongoing to evaluate whether the association may vary by estrogen receptor status or within subgroups of the population defined by age, menopausal status, BMI, and time since last pregnancy. DISCUSSION/SIGNIFICANCE OF FINDINGS: Findings from this study will provide unprecedented knowledge on the association between hypertensive diseases during pregnancy and incidence of breast cancer in the largest cohort of Black women in the U.S.
78696 A Qualitative Cross-Sectional Study of Leadership in a Pandemic: What do Students Value?

Published: March 2021

ABSTRACT IMPACT: This real-world study of what students value in crisis leadership fills an important gap in the literature and may inform future leadership development programs in undergraduate medical education. OBJECTIVES/GOALS: Leadership training is of growing importance and prevalence in medical education. The COVID-19 pandemic provides a unique insight into the qualities students value in leaders. Our qualitative study examined these leadership themes and provides a grounding for future development of leadership programs. METHODS/STUDY POPULATION: A conventional qualitative approach was used in order to allow open expression of ideas related to leadership in a pandemic. The authors developed a 5 free-text question survey instrument aimed to uncover student perceptions of leadership both during the current pandemic and in crises in general. A participant pilot was performed in order to ensure readability and ease of understanding. We used thematic analysis to examine the content of the survey responses, and inductive coding of the responses allowed identification of emerging themes. Medical students at the University of Michigan were surveyed. RESULTS/ANTICIPATED RESULTS: In total, 162 students completed the survey. The demographic characteristics of participants are shown in Table 1. Median age was 25 years old (range, 22-39). There was good representation from the 4 classes in the medical school with 20-30% from each medical school class and 5% of dual degree students. Thematic analysis demonstrated that students value personal characteristics of excellence in their leaders with an orientation towards helping other people. Students believe that leaders must know how to interpret and use information and then that these leaders must be able to communicate expertly to guide organizations. The final theme that emerged is that effective leaders must commit to decisive action. DISCUSSION/SIGNIFICANCE OF FINDINGS: This study took place at a time of unprecedented crises and response examples were grounded in this real-world practice of leadership. These results and themes that emerged fill a critical gap and may facilitate future curriculum development for medical students and trainees.
59473 Clinical and demographic predictors of the need for pharmacotherapy in Neonatal Abstinence Syndrome (NAS)
Authors: Bibi Shawana , Breeze Janis , Terrin Norma , Davis Jonathan 
Published: March 2021

ABSTRACT IMPACT: This work has the potential to help clinicians decide which infants exposed to in utero opioids, will need to be treated early or can be discharged home early based on their risk, thus reducing prolonged hospitalization OBJECTIVES/GOALS: To develop and validate a prediction model with inclusion of clinical and demographic risk factors to identify infants with NAS likely to need pharmacotherapy. METHODS/STUDY POPULATION: A pooled cohort of 761 infants from 5 different studies including 2 trials and 3 observational cohorts will be used to develop the model.All infants >than or equal to 37 weeks gestational age born to mothers with history of OUD will be included. Infants with congenital disorders and severe medical and surgical illnesses will be excluded. Multivariable mixed effects logistic regression modeling will be performed to predict the need for pharmacologic treatment for NAS. Candidate variables will be included based on clinical knowledge and previously published data. Model performance will be evaluated by measuring discrimination using Area Under the Curve (AUC) statistics and calibration. Model will be internally validated using boot strap validation. RESULTS/ANTICIPATED RESULTS: Pending data analysis DISCUSSION/SIGNIFICANCE OF FINDINGS: Opioid Use Disorder in pregnancy has resulted in concurrent rise in NAS incidence. NAS affects opioid exposed infants variably and accurate prediction of its severity and need for treatment remains elusive. Known clinical and demographic factors can predict the need for NAS therapy in opioid exposed infants, aiding clinical decision making.
Comparing country risk and response to COVID-19 in the first 6 months across 25 Organisation for Economic Co-operation and Development countries using qualitative comparative analysis
Authors: Greener Ian 
Published: March 2021

AbstractThis paper explores the contextual and government response factors to the first-wave of the COVID-19 pandemic for 25 the Organisation for Economic Co-operation and Development nations using fuzzy-set qualitative comparative analysis. It considers configurations of: obesity rates; proportions of elderly people; inequality rates; country travel openness and COVID-19 testing regimes, against outcomes of COVID-19 mortality and case rates. It finds COVID-19 testing per case to be at the root of sufficient solutions for successful country responses, combined, in the most robust solutions, with either high proportions of elderly people or low international travel levels at the start of pandemic. The paper then locates its sample countries in relation to existing welfare typologies across two dimensions based on total social expenditure and proportional differences between the GINI coefficient before and after taxes and transfers. It finds that countries generally categorised as “liberal” in most existing typologies did the most poorly in their first-wave COVID-19 response.
A study of Aotearoa New Zealand enterprises: how different are Indigenous enterprises?

Published: March 2021

AbstractIndigenous literature suggests Māori businesses are distinct within Aotearoa New Zealand, due to facing unique challenges and having different operating preferences. It could also be argued that Māori and non-Māori enterprises in the private, public and not-for-profit sectors are identical as a function of operating in similar markets. However, there is a paucity of empirical evidence, and the present article rectifies this with a study of 230 Aotearoa enterprises, including 24 Māori. We test differences and find Māori enterprises report higher cultural capital, which relates to employees' knowledge and skills towards working with and respecting cultural values. However, we find no differences across human capital, relational capital, entrepreneurial culture, and organisational performance. The findings suggest that apart from a culturally specific factor, Māori and non-Māori enterprises appear to be similarly enabled, which provides a useful benchmark for understanding Māori business. We discuss the implications for research.
Europe’s Secessionist Movements and Covid-19
Authors: Parker Jonathan 
Published: March 2021

AbstractFor three European states in particular, the Covid-19 pandemic has served to catalyze pre-existing territorial disputes. While the United Kingdom, Spain, and Belgium have all had very different responses to the pandemic, in all three cases the actions of central and regional government have put existing structures of regional autonomy under strain. In Spain, the pandemic response has become intertwined with the Catalan independence debate (especially in disputes between pro-independence parties), and elsewhere in the country it has cemented co-operative relationships between moderate nationalists and the statewide left. In Belgium, the pandemic has accentuated territorial disputes and further complicated government formation. And in the UK diverging responses to the pandemic have helped boost nationalist movements in the devolved nations; particularly the cause of the Scottish National Party (SNP) and their ambitions to create an independent Scottish state. While the year has been highly significant for secessionist movements in all three states, only in the UK does a decisive shift towards state-breakup seem to have occurred. The article argues that whether or not a secessionist movement benefits from the pandemic is highly contingent on contextual factors, including the performance of state-level governments in responding to the pandemic and the relative autonomy of regional governments during the response.
Detrital zircon geochronology and heavy mineral analysis as complementary provenance tools in the presence of extensive weathering, reworking and recycling: the Neogene of the southern North Sea Basin
Authors: Verhaegen Jasper , von Eynatten Hilmar , Dunkl István , Weltje Gert Jan 
Published: March 2021

AbstractHeavy mineral analysis is a long-standing and valuable tool for sedimentary provenance analysis. Many studies have indicated that heavy mineral data can also be significantly affected by hydraulic sorting, weathering and reworking or recycling, leading to incomplete or erroneous provenance interpretations if they are used in isolation. By combining zircon U–Pb geochronology with heavy mineral data for the southern North Sea Basin, this study shows that the classic model of sediment mixing between a northern and a southern source throughout the Neogene is more complex. In contrast to the strongly variable heavy mineral composition, the zircon U–Pb age spectra are mostly constant for the studied samples. This provides a strong indication that most zircons had an initial similar northern source, yet the sediment has undergone intense chemical weathering on top of the Brabant Massif and Ardennes in the south. This weathered sediment was later recycled into the southern North Sea Basin through local rivers and the Meuse, leading to a weathered southern heavy mineral signature and a fresh northern heavy mineral signature, yet exhibiting a constant zircon U–Pb age signature. Thus, this study highlights the necessity of combining multiple provenance proxies to correctly account for weathering, reworking and recycling.

AbstractIlex paraguariensis, commonly known as yerba mate, is a tree species native to South America. Its commercial value is due to the manufacturing of teas, with potential also in the pharmacological and cosmetic industries. Vegetative propagation of yerba mate is considered an innovation to the traditional production systems based on sexual propagation. The present study aimed to evaluate the rhizogenic potential and chemical attributes of mini-cuttings from 15 yerba mate genotypes, as well as to verify the correlation between phytochemical and rooting-related variables. Mini-cuttings were collected from a pre-existing mini-clonal hedge and the experimental design was completely randomized, with 15 treatments (genotypes), four replications and 10 mini-cuttings per plot. After 120 days, mini-cuttings were assessed regarding rooting, mortality, callogenesis and leaf retention percentages, percentage of mini-cuttings with both calluses and roots, number of roots and average root length. At the time of collection, subsamples from each plot were used for phytochemical analyses including total phenolic compounds, protein, caffeine and theobromine contents and antioxidant activity. Rooting percentages ranged from 5 to 72.5%, with significant variation among genotypes. Adventitious rooting and phytochemical profile of yerba mate mini-cuttings are genotype-dependent. Leaf retention is a relevant factor in the rooting of yerba mate mini-cuttings and the levels of total phenolic compounds, antioxidants and theobromine present in mini-cuttings are negatively correlated components toIlex paraguariensisadventitious rooting.
