Published: January 2021

Modeling the behavior of pedestrians is an important tool in the analysis of their behavior and consequently ensuring the safety of pedestrian traffic. Children pedestrians show specific traffic behavior which is related to cognitive development, and the parameters that affect their traffic behavior are very different. The aim of this paper is to develop a model of the children-pedestrian’s speed at a signalized pedestrian crosswalk. For the same set of data collected in the city of Osijek—Croatia, two models were developed based on neural network and multiple linear regression. In both cases the models are based on 300 data of measured children speed at signalized pedestrian crosswalks on primary city roads located near a primary school. As parameters, both models include the selected traffic infrastructure features and children’s characteristics and their movements. The models are validated on data collected on the same type of pedestrian crosswalks, using the same methodology in two other urban environments—the city of Rijeka, Croatia and Enna in Italy. It was shown that the neural network model, developed for Osijek, can be applied with sufficient reliability to the other two cities, while the multiple linear regression model is applicable with relatively satisfactory reliability only in Rijeka. A comparative analysis of the statistical indicators of reliability of these two models showed that better results are achieved by the neural network model.
The Role of Relational Capital in Anti-Crisis Measures Undertaken by Companies—Conclusions from a Case Study
Authors: Walecka Anna
Published: January 2021

The aim of this article was to present the results of empirical research conducted in enterprises of all sizes operating in Poland and Central Europe. The study focused on the impact of relational capital on the prevention of and intervention in the event of a crisis in a company. The author assumes that there is a link between a company’s relational capital and its susceptibility to crisis phenomena. The research carried out allowed different conclusions to be drawn. It turns out that the studied companies were characterized by a high level of relational capital. Their internal relational capital—particularly the relations between employees and company owners—was especially important to them. Relations of the surveyed companies with external stakeholders were also important. In response to the question about the role of relational capital in anti-crisis measures undertaken by companies, it appears that the relational capital of the companies surveyed allowed them, in their opinion, to avoid many crisis situations. Thanks to the right attitudes of the surveyed companies’ stakeholders, they have often managed to avoid crises. This situation also applies to the recent crisis caused by COVID-19.
Military Barracks as Cultural Heritage in Italy: A Comparison between before-1900- and 1900-to-1950-Built Barracks
Authors: Camerin Federico , Camatti Nicola , Gastaldi Francesco
Published: January 2021

This paper addresses the fundamental role that cultural heritage can play in local development processes to guarantee community wellbeing, quality of life, and quality of society. The enhancement of cultural heritage’s tangible and intangible values may result in sustainable and resilient territory, but a number of issues emerge when dealing with the reuse of specific inherited assets, such as former military barracks. This paper conducts an in-depth analysis of these assets, especially those released from the military after the end of the Cold War. We thus explore the Italian case through the comparison of before-1900 and 1900-to-1950 former military barracks. The objectives are the following. First, to discover how these two types of military sites are approached (or no) as proper heritage. Second, to understand how the reuse management is carrying out and how it deals with conservative and profit-driven approaches towards the achievement of cultural, economic, environmental, and social sustainability. Third, to compare the Italian case with similar international good practices to discover common/different trends and innovative solutions to be applied in Italy.

Protobothrops mucrosquamatus poses a serious medical threat to humans in Southern and Southeastern Asia. Hemorrhage is one of the conspicuous toxicities related to the pathology of P. mucrosquamatus envenoming. Previous in vitro and in vivo studies showed that a silica-derived reagent, sodium silicate complex (SSC), was able to neutralize hemorrhagic and proteolytic activities induced by pit viper venoms, including Crotalus atrox, Agkistrodoncontortrix contortrix and Agkistrodon piscivorus leucostoma. In this study, we validated that SSC could neutralize enzymatic and toxic effects caused by the venom of P. mucrosquamatus. We found that SSC inhibited the hemolytic and proteolytic activities induced by P. mucrosquamatus venom in vitro. In addition, we demonstrated that SSC could block intradermal hemorrhage caused by P. mucrosquamatus venom in a mouse model. Finally, SSC could neutralize lethal effects of P. mucrosquamatus venom in the mice. Therefore, SSC is a candidate for further development as a potential onsite first-aid treatment for P. mucrosquamatus envenoming.
A Neurotoxic Snake Venom without Phospholipase A2: Proteomics and Cross-Neutralization of the Venom from Senegalese Cobra, Naja senegalensis (Subgenus: Uraeus)

Published: January 2021

The Senegalese cobra, Naja senegalensis, is a non-spitting cobra species newly erected from the Naja haje complex. Naja senegalensis causes neurotoxic envenomation in Western Africa but its venom properties remain underexplored. Applying a protein decomplexation proteomic approach, this study unveiled the unique complexity of the venom composition. Three-finger toxins constituted the major component, accounting for 75.91% of total venom proteins. Of these, cardiotoxin/cytotoxin (~53%) and alpha-neurotoxins (~23%) predominated in the venom proteome. Phospholipase A2, however, was not present in the venom, suggesting a unique snake venom phenotype found in this species. The venom, despite the absence of PLA2, is highly lethal with an intravenous LD50 of 0.39 µg/g in mice, consistent with the high abundance of alpha-neurotoxins (predominating long neurotoxins) in the venom. The hetero-specific VINS African Polyvalent Antivenom (VAPAV) was immunoreactive to the venom, implying conserved protein antigenicity in the venoms of N. senegalensis and N. haje. Furthermore, VAPAV was able to cross-neutralize the lethal effect of N. senegalensis venom but the potency was limited (0.59 mg venom completely neutralized per mL antivenom, or ~82 LD50 per ml of antivenom). The efficacy of antivenom should be further improved to optimize the treatment of cobra bite envenomation in Africa.
Recombinant Baculovirus-Produced Grass Carp Reovirus Virus-Like Particles as Vaccine Candidate That Provides Protective Immunity against GCRV Genotype II Infection in Grass Carp

Published: January 2021

Grass carp reovirus (GCRV) leads to severe hemorrhagic disease in grass carp (Ctenopharyngodon idella) and causes economic losses in grass carp aquaculture. Recent epidemiological investigations showed that GCRV genotype II is the dominant subtype in China. Therefore, it is very important to develop a novel vaccine for preventing diseases caused by GCRV genotype II. In this study, we employed a bac-to-bac expression system to generate GCRV-II-based virus-like particles (VLPs). Previous studies have shown that the structural proteins VP3, VP4, and VP38 encoded by the segments S3, S6, and S10 of type II GCRV are immunogenic. Hence, the GCRV-VLPs were produced by co-infection of sf9 cells with recombinant baculoviruses PFBH-VP3, PFBH-VP4, and PFBH-VP38. The expressions of VP3, VP4, and VP38 proteins in GCRV-VLPs were tested by IFA and Western blot analysis. By electron microscopic observations of ultrathin sections, purified VLPs showed that the expressed proteins are similar in shape to GCRV genotype II with a size range from 40 nm to 60 nm. The immunogenicity of GCRV-VLPs was evaluated by the injection immunization of grass carp. The analysis of serum-specific IgM antibody showed that grass carp immunized with GCRV-VLPs produced GCRV-specific antibodies. Furthermore, injection with GCRV-VLPs increased the expressions of immune-related genes (IgM, IFN, TLR3, TLR7) in the spleen and kidney. In addition, grass carp immunized with a GCRV-VLPs-based vaccine showed a relative percent survival rate (RPS) of 83.33% after challenge. The data in this study showed that GCRV-VLPs demonstrated an excellent immunogenicity and represent a promising approach for vaccine development against GCRV genotype II infection.

Stream and terrestrial ecosystems are intimately connected by riparian zones that support high biodiversity but are also vulnerable to human impacts. Landscape disturbances, overgrazing, and diffuse pollution of agrochemicals threaten riparian biodiversity and the delivery of ecosystem services in agricultural landscapes. We assessed how terrestrial invertebrate communities respond to changes in riparian vegetation in Romanian agricultural catchments, with a focus on the role of forested riparian buffers. Riparian invertebrates were sampled in 10 paired sites, with each pair consisting of an unbuffered upstream reach and a downstream reach buffered with woody riparian vegetation. Our results revealed distinct invertebrate community structures in the two site types. Out of 33 invertebrate families, 13 were unique to either forested (6) or unbuffered (7) sites. Thomisidae, Clubionidae, Tetragnathidae, Curculionidae, Culicidae, and Cicadidae were associated with forested buffers, while Lycosidae, Chrysomelidae, Staphylinidae, Coccinellidae, Tettigoniidae, Formicidae, and Eutichuridae were more abundant in unbuffered sites. Despite statistically equivocal results, invertebrate diversity was generally higher in forested riparian buffers. Local riparian attributes significantly influenced patterns in invertebrate community composition. Our findings highlight the importance of local woody riparian buffers in maintaining terrestrial invertebrate diversity and their potential contribution as a multifunctional management tool in agricultural landscapes.
Two-Dimensional Flood Inundation Modeling in the Godavari River Basin, India—Insights on Model Output Uncertainty
Authors: Sharma Vimal Chandra , Regonda Satish Kumar
Published: January 2021

Most flood inundation models do not come with an uncertainty analysis component chiefly because of the complexity associated with model calibration. Additionally, the fact that the models are both data- and compute-intensive, and since uncertainty results from multiple sources, adds another layer of complexity for model use. In the present study, flood inundation modeling was performed in the Godavari River Basin using the Hydrologic Engineering Center—River Analysis System 2D (HEC-RAS 2D) model. The model simulations were generated for six different scenarios that resulted from combinations of different geometric, hydraulic and hydrologic conditions. Thus, the resulted simulations account for multiple sources of uncertainty. The SRTM-30 m and MERIT-90 m Digital elevation Model (DEM), two sets of Manning’s roughness coefficient (Manning’s n) and observed and estimated boundary conditions, were used to reflect geometric, hydraulic and hydrologic uncertainties, respectively. The HEC-RAS 2D model ran in an unsteady state mode for the abovementioned six scenarios for the selected three flood events that were observed in three different years, i.e., 1986, 2005 and 2015. The water surface elevation (H) was compared in all scenarios as well as with the observed values at selected locations. In addition, ‘H’ values were analyzed for two different structures of the computational model. The average correlation coefficient (r) between the observed and simulated H values is greater than 0.85, and the highest r, i.e., 0.95, was observed for the combination of MERIT-90 m DEM and optimized (obtained via trial and error) Manning’s n. The analysis shows uncertainty in the river geometry information, and the results highlight the varying role of geometric, hydraulic and hydrologic conditions in the water surface elevation estimates. In addition to the role of the abovementioned, the study recommends a systematic model calibration and river junction modeling to understand the hydrodynamics upstream and downstream of the junction.
Challenges in Chennai City to Cope with Changing Climate

Published: January 2021

Cities are dynamic systems resulting from the complex interaction of various socio-ecological and environmental developments. Climate change disproportionately affects cities mostly located in climate-sensitive areas; thus, these urban systems are the most critical in modern societies under changing climate scenarios, uncertain disruptions, and urban inhabitants' daily lives. It is essential to analyze the challenges in the metropolitan area through the lens of climate change. The present work analyses the challenges in Chennai, a coastal city in India and one of the chief industrial growth canters in Indian and South Asian region. The challenges are analyzed through the city’s system analysis via land use, green cover, population, and coastal hazards. Land use and green cover changes are studied through satellite images using ArcGIS and assessing coastal risks due to sea-level rise through GIS-based inundation model. There are drastic changes in land-use patterns; the green cover had reduced much, including agricultural and forest cover due to rapid urbanization. The land use has changed to 59.6% of the reduction in agriculture land, nearly 40% reduction in forest land, and 47% of the wetland over time. The observed mean sea level trend for Chennai is + 0.55 mm/year from 1916 to 2015 and the area of 21.75 sq. km is under the threat of inundation to 0.5m sea-level rise. The population growth, drastic changes in land use pattern, green cover reduction, and inundation due to sea-level rise increase the city's risks to climate change. There is a need to ensure that future land-use developments do not worsen the current climate risk level, either through influencing the hazards themselves or affecting the urban system's future vulnerability and adaptive capacity. The study also urges the zone level adaptation strategies to ensure the resilience of the city.

The following research methods were used: analysis and generalization of scientific-methodical and special literature, video analysis, and mathematical statistics. Results. The study included a video analysis of 36 women’s matches and 36 men’s matches of the 2018 World Cup with regard to occurrence of penalty corners. We recorded parameters such as shooting type, shooting time, shooting accuracy, ball receiving, and the moment of realization. The study determined the effectiveness of penalty corners for men's and women's teams. It has demonstrated that the speed of the ball shooting when performing a penalty corner is significantly different for women and men. In men's teams, there is only one type of a penalty corner - from a static position. Women's teams have a large proportion of penalty corners from a static position, but there are also mobile shots and sweeping shots. Conclusion. The analysis of matches of the World Cup 2018 of women’s and men’s leading teams with regard to occurrence of penalty corners has revealed that the effectiveness of a penalty corner for the strongest men’s teams is 23.6%, for women’s teams - 17.8%. Men's teams serve mainly from a static position, while women's teams use 3 types of shots. The factor analysis based on the values of factor weights enabled explanation of tournament tables and creation of a pattern of the winner's team according to the results of penalty corners.

The research purpose was to provide a biomechanical analysis of penalty corner striking techniques in field hockey. Research problems. 1) To identify the boundary phases of a penalty corner; 2) To determine the mechanism of pressure distribution under the feet; 3) To identify the characteristics of an ideal model of spatial-temporal motion of the projection of the center of pressure on the supporting surface when executing a penalty corner. Methods: literature review, biomechanical analysis with the use of a podometric platform, and mathematical statistics. Results. The results of a biomechanical analysis enabled us to register the parameters of pressure distribution under a foot during a penalty corner, and to identify boundary and spatial-temporal phases. We revealed 3 periods in the movement structure: preparation, implementation, and completion. We revealed 5 movement phases: #1 Preparation, #2 Adjustment to a starting position, #3 Start of a stroke, #4 Stroke, and #5 Completion. We identified the values of pressure under a foot in each of the phases of penalty corner and the bio-mechanism of its change and regulation when during penalty corner execution. Therefore, for each phase, pressure changes under the right (R) and left (L) feet from the percentage of body weight were arranged. The arrangement is as follows: #1 – Preparation (R – 72; L – 28%), #2 Adjustment to a starting position (R – 93; L – 7%), #3 Start of a stroke (R – 17; L – 83%), # 4 Completion of a stroke (R – 16; L – 84%), and # 5 – Stick and body motion after a stroke (R-1: L-99%). We identified the characteristics of the ideal model of spatial-temporal motion of the projection of the center of pressure on the supporting surface when executing a penalty corner. We revealed that each phase took a certain time period during the stroke execution: #1 – Preparation (35%), #2 Adjustment to a starting position (22%), #3 Start of a stroke (26%), #4 Completion of a stroke (4%), and #5 Stick and body motion after a stroke (13%). Conclusion. The research findings can enable coaches and athletes to understand the characteristics of an ideal model of the stroke execution, and to get aware of various tools available for its technical support.

Published: January 2021

The purpose of the study is to assess the health status of the 1st – 4th year students in the Department of Drama using the G. Apanasenko method.

The somatic health condition determines the incidence of diseases, the performance of students, and their future vocational opportunities. Monitoring the condition of students is an important component of the physical education system implemented at the universities of theater studies in the framework of "Physical education" and "Stage movement" disciplines.

Methods and organization of research. The paper presents the results of the survey (September 2020) covering 43 students aged 17-21 years (25 boys and 18 girls) using the G. Apanasenko express method of assessing health condition. The authors measured main vital signs (body length and weight, heart rate, blood pressure, VC, EPOC, post-exercise recovery period) and obtained overall assessment of health condition of each student and its individual indices (mass, vital, strength, Robinson).

Research results and their discussion. The research revealed that 53.5% of students have average level of health indicator. However, only 51.2% of indicators fall within the zone of healthy values, while the remaining 48.8% stay below the safe limit. The indicators of 61.1% of girls are in the safe zone, while only 44% of boys fall within this segment. There is a decrease in health indicators of students by the 4th year of study, which is the result of a decrease in their sport activities due to the lack of "Physical education" and "Stage movement" special disciplines.

Analysis of the calculated indices highlighted the challenging components of the overall health assessment. Power index provided the lowest indicators. Girls have higher indicator values than boys, as well as the life index indicators.

Conclusion. The revealed facts contribute to determination of the direction of further research aimed at the refinement of educational programs on physical education and stage movement.
A review of common psychedelic drugs
Authors: Mayet S
Published: January 2021

Psychedelic substances have traditionally been used in medicine and religious rituals. Their use dates back thousands of years with fossil evidence as old as 10 000 years. Throughout the 1950s and 1960s psychedelics were used in clinical studies. These drugs then saw widespread use in hippie culture and were viewed as a drug of abuse with no medicinal value. Currently, psychedelics are being investigated as adjuncts to existing psycho therapeutic approaches including depression and addiction. This article will look at definitions, classifications, effects and basic pharmacokinetics and pharmacodynamics of these drugs. In this review I will refer to this group of drugs as psychedelics.

The results of testing the second hypothesis show that work culture (X1) partially has a positive and significant effect on employee work discipline. The third test results indicate that the leadership variable (X2) partially has a positive and significant effect on employee work discipline.
Meeting Planners: Views of Corporate Social Responsibility Practices and Motivations Across Two Continents
Authors: Musgrave James , Sibley Jonathan , Woodward Simon
Published: January 2021

Interpretation of, and commitment to, corporate social responsibility (CSR) differs from country to country, resulting in variances in implementation. It is theorized that these variances originate from organizational and cultural context. There is limited research dedicated to contextual
variances of CSR in the meetings industry. As such, the objective of this article is twofold: first, to understand whether meeting planners in America and Western Europe differ in their current and future motives for engaging with CSR. Second, to establish whether the differences in motivation
are influenced by their conceptual understanding of CSR or the wider socioeconomic and political environment. The authors analyzed over 1,000 self-reporting questionnaires from meeting planners across the two continents. Results were analyzed using unrelated t tests in order to establish
if the two groups differ in their underlying motives to engage with CSR. An exploratory factor analysis was used to determine how meeting planners conceptualized CSR across the two continents. Results suggests similar strategic motives to engage in CSR. European meeting planners identify egoistic
motives to engage in CSR. In contrast to America, CSR practice in Europe will change in the future as value-driven motives become prevalent. The article provides evidence of context as a defining factor in CSR, where ubiquitous constructs of CSR cannot be easily applied to meeting planners.
The findings demonstrate the incongruent nature of CSR practice. The results advance the application of CSR to meeting planner's practice in both America and Western Europe, reigniting the definitional debate of CSR within the meetings industry.
TOLSTOVSKY TEXT IN WORKS BY A. BLOK
Authors: Kuryanova Valeria V.
Published: January 2021

The article, based on the material of A. Blok’s work, examines the elements of the Tolstoyan text as a nominal supertext of literature. It is argued that the basis of this text is the myth of L.N. Tolstoy, which has been actively developing for a century and a half until today, but at the beginning of the 20th century, when Tolstoy’s tragic departure from his own home became popular, it became especially relevant. The structure of the Tolstoyan myth is analyzed, the mythologies associated with it (mythologized constant representations) created and reproduced by A. Blok in accordance with his own poetic worldview, personal attitude to the work and personality of L.N. Tolstoy. In light of the problem posed, the poet’s lyrics, his articles, and correspondence are examined. Attention is focused on the originality of the Tolstoy text in the creative heritage of Blok, based on the proximity of worldviews, the sacralization of the image of the great writer, rejection of criticism and profanation of the image of Tolstoy in contemporary art, journalism and memoirs. Unlike other modernist movements, the Symbolists did not set the task of overthrowing the idols of the past, but on the contrary, they even defended a certain continuity of traditions, all the more so with such an original author as Blok. But the desire to protect Tolstoy from attacks on his authority also makes it possible to develop a biographical myth about the writer. The question is raised about the features of the perception of this myth in the culture and literature of the first third of the XX century.
Student Development and Service- Learning: A Three-Phased Model for Course Design
Authors: Williams Howe Carrie , Coleman Kimberly , Hamshaw Kelly , Westdijk Katherine
Published: January 2021

Many key resources in service-learning literature offer tools and advice to faculty members for designing effective service-learning courses; these materials typically focus on integrating service-learning effectively into a syllabus, fostering reciprocal partnerships, and using reflection to analyze experience. In addition, a number of research studies have explored the impact of participation in service-learning on student development outcomes. However, very few resources “flip” this equation—that is, there is less information in the literature on how student development theory can inform the effective design of service-learning courses and curricula. This article utilizes an extensive review of student/adult development and learning theory to propose a three-phased model for service-learning course design. Informed by the authors’ experiences working with faculty members and departments, the article provides examples illustrating the potential impact of this approach for individual courses or sequential curricula.

El estilo directo en el discurso teatral. Un estudio a partir del Archivo de Textos Hispánicos de la Universidad de Santiago
Authors: Estévez-Rionegro Noelia
Published: January 2021

Los procedimientos de estilo directo en español han sido ampliamente estudiados desde un punto de vista discursivo en diferentes contextos. Sin embargo, existen todavía ciertas lagunas que dejan sin explorar algunas manifestaciones discursivas que también pueden resultar de interés en un estudio profundo sobre la citación. De este modo, el presente estudio pretende contribuir al retrato de la cita directa en un tipo de discurso tan poco explorado desde el punto de vista gramatical como es el teatral. A partir del estudio de un corpus de ejemplos tomado de las obras de teatro registradas en el Archivo de Textos Hispánicos de la Universidad de Santiago, tratarán de establecerse los procedimientos propios de la citación directa en un tipo de discurso que se crea como imitación de otro y que, además, tiene la particularidad de aunar dos manifestaciones lingüísticas: la lengua escrita que da soporte a la obra como lectura y la lengua oral que, como dramaturgia, trata de emular. Para ello, se atiende a las propiedades formales, gramaticales y semánticas de los enunciados, que revelan una serie de características propias de las construcciones de estilo directo en el discurso teatral que parecen diferenciarlas como clase y sientan las bases de futuros estudios contrastivos respecto a otros tipos de discursos orales o escritos.
Menscheninduzierte Schwingungen bei einer doppelstöckigen Sporthalle in Berlin-Neukölln/Human induced vibrations in a two-storey sports hall located in Berlin-Neukölln
Authors: Höbbel Thomas , Piotti Christoph , Andrich Peter
Published: January 2021

Zusammenfassung Aufgrund des begrenzten Flächenangebotes in urbanen Gebieten müssen Sporthallen häufig mehrgeschossig ausgeführt werden. In Berlin-Neukölln ist für den Neubau der Clay-Oberschule eine doppelstöckige Sporthalle geplant. Die weitgespannten Deckenbinder mit oftmals niedrigen Eigenfrequenzen erfahren eine Schwingungsanregung durch hüpfende, tanzende oder laufende Personen. Die auftretenden Schwingungen haben selten Einfluss auf die Tragfähigkeit des Systems, sondern stellen vielmehr ein Gebrauchstauglichkeitsproblem dar. In der aktuell bauaufsichtlich eingeführten DIN EN 1990 werden grundsätzlich Gebrauchstauglichkeitsnachweise hinsichtlich Schwingungen gefordert. Lastmodelle für die dynamischen Einwirkungen infolge Fußgängerverkehrs, Hinweise zur Modellierung und dynamischen Berechnung des Tragwerkes und differenzierte Grenzwerte für Schwingungen, insbesondere für Sporthallendecken, werden in den Eurocodes und deren Nationalen Anhängen nicht empfohlen. Der Tragwerksplaner muss sich somit bei der Berechnung und Bewertung der auftretenden Schwingungen auf weiterführende Normen und Richtlinien, Erfahrungen aus anderen Projekten oder das Fachschrifttum beziehen. In diesem Beitrag wird über die Schwingungsuntersuchungen für die doppelstöckige Sporthalle der Clay-Oberschule im Rahmen der Entwurfs- und Genehmigungsplanung berichtet. Hierbei wird speziell auf die Modellierung des Tragwerkes für die dynamische Berechnung, geeignete Ansätze für die dynamischen Lasten und die Festlegung der Gebrauchstauglichkeitskriterien eingegangen. Die Ergebnisauswertung der Schwingungsuntersuchung zeigt, dass eine wirtschaftliche Lösung bei dem schwach gedämpften Deckensystem rechnerisch nur durch die Anordnung zusätzlicher Schwingungsdämpfer möglich ist.
Zum Nachweis der Standsicherheit in der tiefen Gleitfuge bei erhöhtem aktivem Erddruck/On the verification of stability at the lower failure plane with increased active earth pressure
Authors: Fellin Wolfgang
Published: January 2021

Zusammenfassung Der Nachweis der Standsicherheit in der tiefen Gleitfuge ist einer der Standardnachweise für eine verankerte Baugrubenwand. Dieser wird derzeit mit einem Nachweisverfahren 2 laut Eurocode 7 geführt, wobei die mögliche Ankerkraft nach Kranz als Widerstand definiert und mit der vorhandenen Ankerkraft als Beanspruchung verglichen wird. Alternativ kann man die Beanspruchung und den Widerstand in der tiefen Gleitfuge miteinander vergleichen. Bei Berechnungen mit nicht erhöhten aktiven Erddrücken liefern beide Methoden mit den aktuell festgelegten Teilsicherheits- beiwerten ähnliche erforderliche Ankerlängen. In diesem Beitrag wird gezeigt, dass die aktuelle Sicherheitsbetrachtung über die mögliche Ankerkraft nach Kranz im Fall der Berücksichtigung erhöhter aktiver Erddrücke für bestimmte Geometrien des Bruchkörpers mechanisch widersprüchliche Ergebnisse liefert. Im Gegensatz dazu liefert die Sicherheitsbetrachtung über die Beanspruchung und den Widerstand in der tiefen Gleitfuge mechanisch konsistente Ergebnisse.
