Controversial Discussion Research Articles

Kharkiv Modernism

In 2022, Docomomo International launched a call for papers on Modern Movement in Ukraine together with Docomomo Ukraine. More than 20 proposals were received, most of them from authors based in Ukraine itself—despite the difficult circumstances. The Docomomo Journal 67 presented a first selection of those articles to display regional and architectural particularities and current challenges of archiving, documenting, protecting, and preserving the modern heritage. Nearly 100 examples of Ukrainian modern buildings were presented in a graphical overview. The modern Ukranian architecture was dominated by Constructivism from the mid-1920s to the early 1930s, with Kharkiv as the epicenter of production, while Socialist Realism with the Stalin Empire emerged from 1932, lasting until 1955, with Kyiv as the capital of Ukraine. From December 1919 to January 1934, Kharkiv was the first capital of the Ukrainian Soviet Socialist Republic and the cultural, economic, and educational center of the new Ukrainian Republic. The status as new capital led to prestigious master plans and construction projects, among them the world-famous Derzhprom building at Freedom Square–as a symbol of Constructivism–or the Kharkiv Tractor Factory–as a symbol of the industrialization of agriculture. The leading role of Kharkiv as a forerunner and capital of Constructivism is often expressed by the famous State Industry House (Derzhprom) built from 1925 to 1928. Being the only modern ensemble in Ukraine nominated as UNESCO World Heritage, it became and still is the focus of identification and pride—despite the many controversial reflections and discussions about the conservation efforts and changes carried out since the original construction in the 1950s and after the year 2000. This explains the many articles dealing with Freedom Square and Dherzprom as a reaction to the call for papers in 2022 and also Docomomo International’s commitment to dedicate this special issue of the Docomomo Journal to Kharkiv under the title From Constructivism to Modernism in Kharkiv.

Alpha-band Brain Dynamics and Temporal Processing: An Introduction to the Special Focus.

For decades, the intriguing connection between the human alpha rhythm (an 8- to 13-Hz oscillation maximal over posterior cortex) and temporal processes in perception has furnished a rich landscape of proposals. The past decade, however, has seen a surge in interest in the topic, bringing new theoretical, analytic, and methodological developments alongside fresh controversies. This Special Focus on alpha-band dynamics and temporal processing provides an up-to-date snapshot of the playing field, with contributions from leading researchers in the field spanning original perspectives, new evidence, comprehensive reviews and meta-analyses, as well as discussion of ongoing controversies and paths forward. We hope that the perspectives captured here will help catalyze future research and shape the pathways toward a theoretically grounded and mechanistic account of the link between alpha dynamics and temporal properties of perception.

Between nature and culture - Interpreting students' sexuality in physical education.

As sexuality in physical education (PE) is often treated as a taboo subject, social media platforms, online chats, and internet forums are emerging as spaces where it is negotiated more openly and broadly by current and former actors of the field. This paper contributes to a better understanding of the discursive construction of sexuality in PE in such online communication. In line with The Sociology of Knowledge Approach to Discourse (SKAD) we investigate basic schemes of interpretation of sexuality with a heterogeneous sample of threads (17 threads from seven different online forums) on different PE situations in Germany. The threads are analyzed using grounded theory coding procedures. Our discourse analysis reveals that the multifaceted and often controversial online discussions are structured by two dominant schemes of interpreting students' sexuality in PE, both of which are differentiated in complex ways: The online communication draws on - and by that reproduces - a nature and a culture perspective on constellations of body, sex, gender, and sexuality. We detail how from each perspective, different knowledge about these constellations, different everyday phenomena and problems in PE, and different norms for dealing with these phenomena and problems become important. Discussing these results in the context of previous literature, we argue that it is important to address sexuality in a subject-specific approach and take the discursive knowledge and fundamental schemes of interpretation into account that shape the (im-)possibilities of addressing sexuality in PE.

가짜뉴스의 생산과 전파, 그리고 규제

Fake news reveals the most stimulating problem of the times. Academic research is expanding as controversy increases, but it is difficult to obtain a comprehensive understanding of fake news unless a large amount of research results are examined one by one due to the complex intertwining of various sub-topics. Therefore, this paper aims to gain a macroscopic understanding of the production, dissemination, and regulation of fake news through a single research result. First, the current major discussions and issues on the concept and scope of fake news were investigated, and the causes and propagation processes of fake news were reviewed to confirm how changes in the media environment and human psychology affect the spread of fake news. It also investigated the controversial discussion on the regulation of fake news and suggested that the regulation should be minimized in terms of freedom of expression and that it is desirable to be implemented in an alternative way, such as technical regulation. It is hoped that this article can contribute to streamlining the theoretical review of the research field, especially the convergence academic field, which finds new ways to effectively manage and regulate fake news by providing a macroscopic understanding of fake news through the above discussion.

Influence of Cementation Mode and Ferrule Design on the Fatigue Resistance of Monolithic Zirconia Endocrowns.

Background: Classic endocrowns made of dental ceramics are considered a promising alternative to traditional post-endodontic restorations. The use of circular ferrules in endocrowns is a topic of controversial discussion. Therefore, the present study aims to evaluate the effect of ferrule design and cementation mode on the fatigue resistance of zirconia endocrowns. Methods: Eighty human molars were divided into four groups (n = 20): NFC (no-ferrule, conventional cementation), NFA (no-ferrule, adhesive luting), FC (ferrule, conventional cementation) and FA (ferrule, adhesive luting). Both the classic and the modified endocrown preparation with a two-millimeter ferrule design were carried out. Endocrowns were fabricated from zirconia using the CEREC system. After thermocycling, specimens were loaded according to the step-stress test up to 1500 N. Results: Failure rate was low; 88.8% of total specimens passed the step-stress test. Fractures were distributed between all groups; no significant differences in fatigue resistance were detected for preparation design and cementation mode. Conclusions: Endocrowns appear to be a promising concept for endodontically treated molars. Ferrule and also cementation mode have only a minor influence on fatigue resistance of zirconia endocrowns. However, at very high forces, the marginal area of the ferrule represents a weak point.

Acetaminophen Hepatotoxicity: Paradigm for Understanding Mechanisms of Drug-Induced Liver Injury.

Acetaminophen (APAP) overdose is the clinically most relevant drug hepatotoxicity in western countries, and, because of translational relevance of animal models, APAP is mechanistically the most studied drug. This review covers intracellular signaling events starting with drug metabolism and the central role of mitochondrial dysfunction involving oxidant stress and peroxynitrite. Mitochondria-derived endonucleases trigger nuclear DNA fragmentation, the point of no return for cell death. In addition, adaptive mechanisms that limit cell death are discussed including autophagy, mitochondrial morphology changes, and biogenesis. Extensive evidence supports oncotic necrosis as the mode of cell death; however, a partial overlap with signaling events of apoptosis, ferroptosis, and pyroptosis is the basis for controversial discussions. Furthermore, an update on sterile inflammation in injury and repair with activation of Kupffer cells, monocyte-derived macrophages, and neutrophils is provided. Understanding these mechanisms of cell death led to discovery of N-acetylcysteine and recently fomepizole as effective antidotes against APAP toxicity.

Individualized approach for MEN1-associated duodenopancreatic neuroendocrine neoplasms

Multiple endocrine neoplasia type 1 (MEN1)-associated duodenopancreatic neuroendocrine neoplasms (dpNEN) represent the most frequent syndrome-associated cause of death, but the adequate treatment is sometimes considered controversial. Presentation of possible diagnostic and therapeutic options for MEN1-associated dpNENs. In this review article retrospective case studies, expert recommendations, national and international guidelines as well as personal experiences were analyzed and evaluated. Due to early detection programs and the use of the most modern imaging techniques, dpNEN are nowadays diagnosed much earlier. Nonfunctional pNENs currently represent the most frequent dpNENs with about 70%, followed by gastrinomas and insulinomas. Regardless of their functional activity, dpNENs with asize of > 2 cm are generally an indication for surgery. The choice of the optimal treatment strategy, however, in most cases remains the subject of controversial discussions, although nowadays surgery should always be performed in an organ-preserving and minimally invasive way when feasible. Recurrences or new dpNENs are expected in more than 60% of cases, necessitating areoperation in up to 40% of these cases. Duodenopancreatic resections and reoperations can be carried out safely by experienced practitioners and with an acceptable level of risk. The planning of treatment requires careful consideration of the suitable timing, the extent of the operation, the risk of recurrence and potential morbidities. Furthermore, preserving pancreatic function and the quality of life is of utmost importance. In view of the complexity of the disease, MEN1 patients should be treated in specialized centers.

Rydberg electron stabilizes the charge localized state of the diamine cation

A previous controversial discussion regarding the interpretation of Rydberg spectra of gaseous dimethylpiperazine (DMP) as showing the co-existence of a localized and delocalized mixed-valent DMP+ radical cation is revisited. Here we show by high-level quantum-chemical calculations that an apparent barrier separating localized and delocalized DMP+ minima in previous multi-reference configuration-interaction (MRCI) calculations and in some other previous computations were due to unphysical curve crossings of the reference wave functions. These discontinuities on the surface are removed in state-averaged MRCI calculations and with some other, orthogonal high-level approaches, which do not provide a barrier and thus no localized minimum. We then proceed to show that in the actually observed Rydberg state of neutral DMP the 3s-type Rydberg electron binds more strongly to a localized positive charge distribution, generating a localized DMP* Rydberg-state minimum, which is absent for the DMP+ cation. This work presents a case where interactions of a Rydberg electron with the underlying cationic core alter molecular structure in a fundamental way.

Трансформация рисков в банковской системе в условиях цифровизации бизнеса

This material attempts to consider individual problems and identify emerging contradictions in the digital transformation of the banking business. The author expresses his opinion regarding the feasibility and appropriateness of the digital transformation of banks and the economy as a whole. Today, the mass introduction of digital technologies is becoming increasingly widespread in the world, being, in fact, a global trend, a global startup. At the same time, the feasibility and possible consequences of global digitalization are today the subject of active and controversial discussion among both representatives of theory and practitioners, especially in the financial and banking sector, the risks of which are equally significant for banks and their partners and clients. The development of information technologies in the banking sector creates worsening problems and vulnerabilities in the transformation of banks’ business models due to the insufficient alternatives to security systems, as well as the legal vacuum.

Increasing winter wheat yield and nitrogen utilization, and reducing residual soil nitrogen in semi-humid areas: A study matching deep fertilizer application with regional water scenarios

The deep fertilizer application (DF) has been recommended as an effective strategy for promoting crop growth and yield formation. However, the controversial discussion revolves on the challenge of effectively using DF to simultaneously increase crop nitrogen (N) uptake and minimize residual nitrate contents to enhance N utilization efficiency. Based on a precipitation manipulation experiment conducted during 2019–2022 in a semi-humid area, we examined how annual precipitation amount during wheat growing season (125 mm = dry year; 200 mm = normal year; 275 mm = wet year) and the soil water storage before sowing (500 mm, SWSS500; 400 mm, SWSS400; 300 mm, SWSS300) variability affected the N uptake, N utilization efficiency, yield, and residual soil nitrate content in wheat fields treated with N fertilization at different depths (conventional surface fertilization depth of 5 cm: D5; 15 cm: D15; 25 cm: D25; 35 cm: D35). A complementary field experiment was also performed under natural rainfall condition using the 15N tracer technique to quantify the fate of fertilizer-N and 15N use efficiency (15NUE). 15N analyses showed that DF (D15, D25 and D35) significantly increased 15NUE by improving wheat 15N uptake (5.8–15.3%) and reducing potential 15N loss (9.6–12.3%) compared with D5, but the residual soil 15N in the 0–1.0 m layer increased (13.2–26.3%) as the fertilization depth increased (p < 0.05). The simulated precipitation experiment showed that compared with D5, DF significantly increased wheat N uptake, N utilization efficiency and yield by 1.4–16.4%, 1.4–14.0% and 3.3–21.5%, respectively, in the dry and normal years. In the wet year, N uptake, N utilization efficiency and yield under D15 increased by 1.9–9.8%, 2.1–11.1% and 2.2–13.4% compared to other fertilization depth treatments (p < 0.05). SWSS500 and SWSS400 significantly increased the N uptake (9.8–65.0%) and yield (0.6–69.3%) under all fertilization depth treatments irrespective of the annual precipitation amount than SWSS300 (p < 0.05). DF increased the residual NO3–-N concentration (0–2.0 m soil layer) by 2.2–7.3% compared to D5 across all annual precipitation amounts and SWSS levels, and D35 increased the maximum downward movement of NO3–-N to 1.4 m under wet year within SWSS500. DF at the depth of 14–20 cm effectively improved wheat N uptake and yield as well as minimizing the residual soil NO3–-N content. Applying moderate DF can enhance sustainable wheat production with high efficiency and yields in semi-humid regions.

Maternal and Perinatal Outcome After Induction of Labor Versus Expectant Management in Low-risk Pregnancies Beyond Term.

Due to still controversial discussion regarding appropriate termination of low-risk singleton pregnancies beyond term, this retrospective study aimed to evaluate maternal and perinatal outcomes depending on gestational age and obstetric management. This is a retrospective cohort analysis including 3.242 low-risk singleton deliveries at the Department of Obstetrics of the University Hospital of Cologne between 2017 and 2022. According to current national guidelines, the cohort was subdivided into three gestational groups, group 1: 40+0-40+6 weeks, group 2: 40+7-40+10 weeks and group 3>40+10 weeks. In our cohort, advanced gestational age was associated with higher rates of secondary caesarean sections, lower rates of spontaneous vaginal deliveries, higher rates of meconium-stained amniotic fluid and depressed neonates with APGAR < 7 after 5 min. Analyzing obstetric management, induction of labor significantly increased the rate of secondary sections and reduced the rate of spontaneous deliveries, while the percentage of assistant vaginal deliveries was independent from obstetric management and gestational age. Induction of labor also significantly enhanced the need for tocolytic subpartu and epidural anesthesia and caused higher rates of abnormalities in cardiotocography (CTG), which also resulted in more frequent fetal scalp blood testing; however, the rate of fetal acidosis was independent of both obstetric management and gestational age. Our study supports expectant management of low-risk pregnancies beyond term, as induction of labor increased the rate of secondary sections and did not improve perinatal outcome.

Black Forest Melody: Between Philosophical Kitsch and Identitarian Ideology: Heidegger’s Pastoral World-View in the Memorial Address. Trial on a Classification

Abstract Martin Heidegger is still subject to controversial discussions about his political views. The question in the centre of the discussions is not if he was politically on the far right, but how far right he was, and also how far right his philosophy is. However, the details of Heidegger’s political approaches in his work are largely disguised and hidden behind Heidegger’s typical writing style, which has remained undefined for so long. There is a short essay in Heidegger’s work that may shed light on the roots and details of his ethnic-identity thinking: “Memorial Address”.

Single-sex schools VS mixed-gender schools: comparing impacts

This article provides an overview of the advantages and disadvantages of same-sex and mixed-gender schooling, the importance of diverse educational environments, the strategies for addressing disparities and promoting equality in education. The advantages of same-sex schools include potential benefits for academic achievement, social development, and the promotion of gender equity. However, disadvantages such as reinforcing gender stereotypes and limiting cross-gender interactions should be considered. Mixed-gender schools offer advantages such as diverse social interactions, balanced perspectives, and challenging gender stereotypes. However, potential disadvantages include gender disparities in attention and participation and the perpetuation of gender biases. Creating diverse educational environments is crucial for promoting positive outcomes in academic achievement, social development, cultural competence, and well-being. Strategies for addressing disparities and promoting equality include improving access to education, addressing gender disparities, prioritizing diversity and inclusion, enacting supportive legislation and policies, and engaging with communities. By implementing these strategies, educational institutions can create more equitable and inclusive learning environments. What makes this study particularly timely and relevant is the recent development of same-sex schools versus mixed schools as a political issue in Turkey. There are controversial discussions about this matter, and our research addresses these concerns with empirical evidence and a nuanced perspective.

A comment on “Singular and nonsingular black holes using the Gaussian distribution”

In this work, we join the controversial discussion on singular and nonsingular black holes using the Gaussian distribution. Our result which uses correct boundary conditions shifts the debate in favor of regular black holes at the center. The present findings add new insights into the ongoing discussions surrounding singularities in black hole solutions of the Einstein equations.

The principle of solidarity and hydrogen markets in the European Union

Abstract With the OPAL-Judgment, the CJEU stated very clearly that the principle of solidarity—implemented in Article 194 TFEU with reference to a ‘spirit of solidarity between Member States’—has legally binding effect on EU institutions and EU Member States in the field of energy law. This ruling marks the end of a long and controversial academic discussion on the nature of the solidarity principle. At the same time, the ruling is just the beginning of further legal research on what exactly the content of the obligations and possible conflicts with Member States sovereignty under Article 194(2) TFEU is. The following article analyses the effects of the principle of energy solidarity on the nascent regulatory framework on hydrogen markets in the European Union (EU). It is common sense that those markets shall evolve swiftly to achieve emission reduction goals. There is no European regulation on pure hydrogen markets in force yet, but some EU Member States have already taken legislative action. Against this background, the article will particularly assess the impact of the principle of solidarity on national measures regarding network planning and hydrogen import.

The NFL's Pro Bowl Was Broken? Considering Players’ Incentives

This article examines the growing trend of NFL players to forego participation in the league's yearly All-Star exhibition game, the Pro Bowl. Viewership of the Pro Bowl has been substantially lower than the average game day in recent years, causing controversial discussions about the viability of the game and its future. As a consequence, the league revised the Pro Bowl's concept entirely in 2022. Since the major determinant of viewership demand is the participation of (superstar) players, this article analyses the individual athletes??? economic incentives in the decision to participate. To this end, it models the athlete's decision as a rational evaluation of cost???benefit under incentives of monetary reward and punishment. It uses unbalanced panel data on Pro Bowl players from the Super Bowl era (1971???2019), alongside viewership data and official league data. It applies a range of econometric methods (Pearson correlations, graphical examination) to evaluate hypotheses about the players’ decision-making process. It concludes that the incentives to participate in the Pro Bowl for the majority of players–especially viewership-driving superstar players–were weak. The monetaryincentives in their previous form were not an efficient way of positively manipulating the percent age of superstars in the game. If the goal was higher demand from players, the incentive structure had to be changed. Such changes are, inter alia, the reduction of costs for participation in the form of minimizing the risk of injuries. Furthermore, possible changes to the design of the incentive structure are proposed that contain general learnings for the design of such events.

Building Political Discourse Skills: Students as Teachers

In a highly polarized political environment, political discourse on divisive topics is all the more important. Heeding the many calls for higher education to teach political discourse skills, this study investigates the impact of political discourse lessons in a college-level, political science classroom. Further, it explores the effectiveness of student-peers as teachers. The study finds peers, compared to faculty, are better able to relate to students, and this strength is ideal for teaching subjects that require social connections such as the active listening and perspective taking techniques. Discussion of sensitive political topics can easily lead to discomfort and uneasiness. Our findings suggest that student learners may be more receptive to peer-leaders than to instructors when it comes to such situations. Further peer-teachers experienced increased comfort levels when involved in controversial political discussions and increased ability to engage in political dialogue.

Exacerbation of chronic obstructive pulmonary disease: discussion of controversies. A review

The paper discusses the controversial issues of infectious exacerbation of chronic obstructive pulmonary disease. Researchers and practitioners share a common understanding of rational patient management, which involves the evolution of exacerbation terminology, the impact of viral infection and air pollutants, the significance of biomarkers, and the appropriate antibiotic therapy regimens. Clinical reflections on the current causes of chronic obstructive pulmonary disease exacerbations and modern therapeutic options are presented.

Testing Okun’s Law: Evidence From the Western Balkan Countries

Sustainable economic growth and reducing unemployment stood at the heart of each monetary policy. Despite controversial discussions among scholars, Okun’s Law remains a valuable tool for measuring the relationship between economic growth and the unemployment rate. The study covers the six Western Balkan (WB) countries using quarterly unemployment and economic growth data from 2005 to 2019. The results were obtained from the Vector Autoregressive Model, Granger Causality Test, and Impulse Response Function. The findings show that the GDP growth rate has no influence on the unemployment rate in the case of six Western Balkan countries. From the policy perspective, the outcomes of this study provide valuable indications for the policymakers in WB countries on the importance of economic growth in reducing the unemployment rate.

Dynamics in between Structural and Electrical Properties of as Grown ZnO Thin Films by Thermal ALD

The mechanism behind n-type conductivity of undoped ZnO films are not understood well. One and two dimensional defects (grain boundaries, dislocations), and zero dimensional stoichiometric point defects (vacancies, self-interstitials and impurities) play a crucial role in determining the electrical properties of ZnO. All defect mechanisms are strongly controlled by the growth method and conditions. While it is more straightforward examining the one and two dimensional defects, measuring and unveiling the mechanism behind the zero dimensional point defect contribution and their sole effect on the electrical properties are challenging. This is why there has been controversial discussion of results among experimental and computational works relating physical and chemical properties of ZnO to sustainable electrical properties. In this study, to correlate the dynamics in between structural and electrical properties of ZnO grown by thermal ALD; growth temperature, DEZ and DI water precursor pulse times, DEZ/DI water precursor pulse ratio, and N2 purge time were varied. To obtain growth condition specific structural and electrical properties; XRD, AFM, profilometer, ellipsometry, XPS/CasaXPS, UV-VIS spectrometer, Hall-Effect measurements were utilized. Although, there was no strong correlation for oxygen vacancies, the contribution of hydrogen impurities, zinc interstitials and oxygen vacancies to conductivity was observed at different growth conditions. Lowest resistivity and highest average % transmittance were obtained as 6.8x10-3 ohm.cm and 92% in visible spectrum (380-700 nm), respectively.
