Development of GPS time-based reference trajectories for quality assessment of multi-sensor systems
Authors: Vogel Sören , Hake Frederic 
Published: May 2024

Abstract
The development of multi-sensor systems (MSSs) goes hand in hand with assessing the quality of these complex systems. Therefore, reliable reference information of superior accuracy is essential for validation, serving as ground truth. When the assessment is based on 3D point cloud comparison, appropriate reference environments with suitable geometries are required. However, validation of an MSS can also be performed directly on its 3D position or even its 6D pose. This is particularly suitable for systems without sensors for environmental acquisition. When using kinematic measurement systems, the temporal relationship between the MSS and the reference trajectory must be considered, which can be challenging. Modern sensors of an MSS are often synchronized to GPS time. However, this global time information is not provided for high-accuracy tracking sensors such as robotic total stations (RTSs) or laser trackers (LTs). Instead, only a reference to an internal sensor time is implemented, which does not meet the highest quality requirements for reference trajectories. Depending on the motion speed, time offsets in the millisecond range can lead to significant trajectory inaccuracies. This paper presents investigations for GPS time synchronization of the polar measurement elements of both RTS and LT from Leica Geosystems. While the LT uses a precise trigger signal for the time link, the RTS requires the Measure & Stream application provided by the instrument manufacturer. The two different approaches are presented theoretically. Based on empirical long-term studies, their possibilities and limitations are critically discussed. For the high-frequency LT, reference trajectories with precise synchronization based on GPS time can be reliably realized. With an RTS, improved synchronization can be achieved by using Measure & Stream. Thus, 43 % lower tangential deviations from the reference could be achieved compared to the raw data. However, there are still inconstant time offsets of 63.9 ms on average. Depending on the speed of the target, this can lead to significant position deviations. Further investigations are required. In general, the developed approaches for the realization of GPS-synchronized reference trajectories can be used not only for the quality assessment of MSS, but also for monitoring or kinematic positioning applications.
Dynamic Bunching Estimation with Panel Data
Authors: Marx Benjamin M. 
Published: May 2024

Abstract
Bunching estimation of distortions in a distribution around a policy threshold provides a means of studying behavioral parameters. Standard cross-sectional bunching estimators rely on identification assumptions about heterogeneity that I show can be violated by serial dependence of the choice variable or attrition related to the threshold. I propose a bunching estimation design that exploits panel data to obtain identification from relative within-agent changes in income and to estimate new parameters. Simulations using household income data demonstrate the benefits of the panel design. An application to charitable organizations demonstrates opportunities for estimating elasticity correlates, causal effects, and extensive-margin responses.
A novel chaotic artificial rabbits algorithm for optimization of constrained engineering problems
Authors: Duzgun Erhan , Acar Erdem , Yildiz Ali Riza 
Published: May 2024

AbstractThis study introduces a novel metaheuristic algorithm of optimization named Chaotic Artificial Rabbits Optimization (CARO) algorithm for resolving engineering design problems. In the newly introduced CARO algorithm, ten different chaotic maps are used with the recently presented Artificial Rabbits Optimization (ARO) algorithm to manage its parameters, eventually leading to an improved exploration and exploitation of the search. The CARO algorithm and familiar metaheuristic competitor algorithms were experimented on renowned five mechanical engineering problems of design, in brief; pressure vessel design, rolling element bearing design, tension/compression spring design, cantilever beam design and gear train design. The results indicate that the CARO is an outstanding algorithm compared with the familiar metaheuristic algorithms, and equipped with the best-optimized parameters with the minimal deviation in each case study. Metaheuristic algorithms are utilized to succeed in an optimal design in engineering problems targeting to achieve lightweight designs. In this present study, the optimum design of a vehicle brake pedal piece was achieved through topology and shape optimization methods. The brake pedal optimization problem in terms of the mass minimization is solved properly by using the CARO algorithm in comparison to familiar metaheuristic algorithms in the literature. Consequently, results indicate that the CARO algorithm can be effectively utilized in the optimal design of engineering problems.
The Prevalence of Italian Lexical Components in the Montenegrin Magazine Zeta
Authors: Brajičić Cvijeta 
Published: May 2024

Summary
In this contribution we deal with the presence of lexemes originating from the Italian language or its dialects in the articles in the Montenegrin literary magazine Zeta, which was published in Cetinje during the second half of 1885. Besides the Montenegrin authors, other writers using different variants of the Shtokavian dialect also published their works in this journal, in which the translations of nine foreign authors were printed as well. Our first goal is to determine the similarities and differences in the presence of Italianisms conditioned by the author’s origin. Considering the greater exposure of the language in Montenegro to the influence of Italian and its dialects, it can be assumed that the Italian lexical component might be more present in the articles by Montenegrin authors than in the literary works of those who used other variants of Shtokavian. In addition, we want to verify whether the type of literary text affected the presence of Italianisms, starting from the assumption that the lexicon of Italian origin is more widely present in prose works that deal with topics related to everyday life than in poetry or in texts of a professional nature. Finally, we aim to determine to what extent the Italian lexis registered in our corpus is present in the dictionaries of Italianisms in Montenegrin vernaculars, is it adapted in the same way, and whether it appears with the same meaning or tends to present certain meaning variations.
Normative aspects and adoption of orthographical content in Montenegrin higher education
Authors: Tepavčević Miodarka 
Published: May 2024

Summary
The development of literacy in Montenegrin society is a very reliable indicator of the state and level not only of the general culture and education, but also of the social culture. This lends immense significance to any work on improving the language culture in Montenegro in all of its diverse manifestations, as well as to the popularisation of the basic principles of good literacy. Orthography has an important place within the entire course of schooling in the Montenegrin language syllabus, and so it is very important to be developing and encouraging skills of linguistic expression among the student population, that is, perfecting their spoken and written use of language. In this paper we will deal with the normative aspect of students’ writing skills in the Montenegrin system of higher education. Our primary goal is to establish the quality of written expression and to highlight omissions in the application of orthographic knowledge of Montenegrin language to further contribute to the enhancement of functional knowledge associated with the orthographical culture of the student population in Montenegro. The sample consists of 100 first-year students from the Department for German Language and Literature of the Faculty of Philology and 100 students from the study programme for Translation (English/Russian and English/French group). Qualitative methodology was used to analyse the prevalence of certain types of mistakes in student tests, and comparative analysis of the tests was aimed at showing the degree of application of orthographical norms by students. It is nothing new that orthographical knowledge among students is not at a satisfactory level, and the results of this study confirm the hypothesis that the level of adoption of orthographical rules is not in line with the defined outcomes of the curriculum for Montenegrin language, as well as there being certain differences between students of different study programmes. Our analysis shows that one of the basic goals of the orthography of the Montenegrin language is not fully realised – the enabling of students to apply standard-level writing rules and the raising of students’ awareness of the importance of standard language norms. It is evident that students adopt orthographical rules that are fragmented and that orthographical principles are not viewed as a system, as evidenced by examples of the deviation from the norms.
Rephrasing the teacher's role in the 21st century: Personal responsiveness and educational responsibility in a heterogeneous world
Authors: Bicsák Zsanett Ágnes 
Published: May 2024

AbstractThis paper argues that the mitigation of the normative pedagogy in the value heterogenous world has elicited the need to rephrase the teacher's role. While this study cannot reflect on all issues that have recently arisen, some core questions are addressed to examine the teacher-student relationship and highlight a few principles that teachers need to be aware of. This study links to previous works on responsive pedagogy, accepting the ambition to respond to individual needs but also discussing collective terms such as human freedom and cultural differences, which impact children's perspectives.Accordingly, this paper is an attempt to provide an interdisciplinary framework based on educational philosophy, psychological evidence, and ethnographic studies to discuss the conflict between individual and community interests, basic human needs, individual differences, and ethical issues arising from diverse cultural backgrounds, and some contemporary phenomena that have affected the operations of schools. As a result, following a critical review of the introduced concepts, this paper suggests considering some educational responsibilities that may improve teachers' practice in the 21st century.
Real-world evidence of the collective effects of psychedelic therapy: Evaluating from the grassroots
Authors: Noorani Tehseen , Liebert Rachel Jane 
Published: May 2024

AbstractWith a surge in critiques levelled against the evidence generated by randomised controlled trials in the study of psychedelic-assisted therapy (PAT), and the legalization of PAT in select jurisdictions such as Australia, and Oregon and Colorado in the United States, we consider what form the real-world evidence of its effects could take. Specifically, we propose to complement individual-level data-gathering (the usual remit of pharmacovigilance procedures) with evidence of PAT's collective effects. Taking our cue from long-standing claims that psychedelics are agents of social transformation, we draw upon the ‘transformative paradigm’ of evaluation, an approach that is itself oriented around social justice and change vis-à-vis marginalised expertise – or what we approach as ‘the grassroots’. To illustrate the potential of such grassroots evaluations, we offer eight examples of social issues that have been discussed in relation to PAT and psychedelics use and, for each, discuss the kinds of expertise that could be brought into the evaluation team and the kinds of questions that could be asked. We further describe our grassroots approach according to three values inspired by the qualities of grass roots themselves: rhizomatic accountability, dark reflexivity, and more-than-human hosting. We argue that these values align with the contemporary experience, practice, and context of PAT. We hope to generate discussion, innovation, and – ultimately – action toward specific study designs that are adequate to the task of documenting, and working with, the transformative potential of psychedelics in contemporary medicalized societies.
“You are Needed and You Exist”: Motivation for Social Participation of Older Activists, Rostov Oblast, Russia
Authors: Kienko Tatyana S. 
Published: May 2024

The article aims to identify the sociological approach’s perspective on the reasons behind the continued social engagement of older individuals. In 2021, leaders and activists of social participation practices in the Rostov Oblast aged 65 to 90 years (N = 18) were interviewed. These interviews were analyzed using grounded theory to identify the central motivation for socially significant activities as the desire to attain life satisfaction through contributing positively to others. The participants share comparable socio-demographic and biographical features, including higher education, managerial positions, leadership roles, and involvement in socially significant professions or activities throughout their lives. This indicates that their engagement in social participation is a culmination of their lifetime experiences, thereby supporting the concepts presented by “life course” theories. Motives that are commonly cited include fulfilling moral obligations, establishing connections with important individuals and communities, acquiring resources, gaining social approval and recognition, preserving identity and status, prolonging social life, and ageing postponement. This enables us to discuss the social participation of older adults as a means to combat the aging process, extend social engagement, and advocate for recognition within the frameworks of social exchange theories and the struggle for recognition. Through social participation, individuals accumulate goals and expand their motivational structure, which can result in generativity, i.e., a desire to contribute to improving the lives of others and future generations. This particular type of intrinsic motivation integrates various goals, including those for oneself, for others, with others, and for social change, leading to sustained motivation. The leaders and activists prioritize different motives for social participation. For the former, social recognition, freedom, generativity, and social participation are significant while community involvement is valued more by the latter group. The informants’ motives for participation are consistent with V. Gerchikov’s typological concept of labor motivation and the model of older people’s motivation for social participation as an embodiment of values.
Unearthing the Role of Cultural Perception in Homeownership Behavior: A Conceptual Exploration
Authors: Mulyadi Mulyadi , Ubaidillah Nur Zaimah 
Published: May 2024

Homeownership, viewed as a form of economic behavior, warrants a comprehensive examination considering individual perspectives. This study seeks to redefine cultural perception as an additional variable that extends the influential Theory of Planned Behavior, which serves as the foundational framework for studies in economic behavior. It presents a conceptual framework introducing the pivotal concept of cultural perception in the analysis of homeownership, drawn from an extensive literature review in economics and housing. The study delves into the notions of cultural dimensions, norms rooted in culture, homeownership, Theory of Reasoned Action (TRA), and Theory of Planned Behavior (TPB), addressing the existing gap regarding the “cultural influence” within the TPB framework. Furthermore, this study introduces a novel perspective by expanding TPB by incorporating perception variables linked to cultural values, forming a synthesis of economics, cultural, and psychological disciplines. A metric for assessing perception concerning cultural values is also proposed to effectively encapsulate the essence of the homeownership concept. This study is anticipated to augment the precision and comprehensiveness of investigations into the dynamics of homeownership behavior, and thus enrich the behavioral literature by integrating ideas from diverse disciplines.

Published: May 2024

Aim. To describe the methods used to assess the implementation of new national tobacco and nicotine control policies in the regions of the Russian Federation (EPOHA-RF 2).Material and methods. An online survey sample was designed to include a minimum of 1000 respondents in each region, including current smokers and/or users of electronic nicotine delivery systems (ENDS) and former smokers and/or users of ENDS who quit within the past 3 years (800:200 ratio). Participants were aged 15 and older and resided in 12 regions of the Russian Federation. The sample was collected using the river sampling method and was quota-based by sex, age, and settlement type using 2022 Rosstat data. Weighting coefficients were calibrated against control indicators from nationally representative Rosstat surveys. Data were collected in 2023 using a questionnaire programmed on an online platform for self-completion by respondents. The questionnaire included 74 measurable parameters aligned with the anti-tobacco law.Results. The total sample size across the 12 regions was 12662 individuals as follows: Moscow (n=1094), St. Petersburg (n=1041), Chuvash Republic (n=1046), Krasnodar Territory (n=1047), Primorsky Territory (n=1062), Arkhangelsk Region (n=1042), Astrakhan Region (n=1077), Belgorod Region (n=1048), Novosibirsk Region (n=1030), Orenburg Region (n=1042), Samara Region (n=1071), and Tyumen Region (n=1062). The distribution of respondents within each region corresponded to the age, sex, and settlement type distribution of smokers/ENDS users reported by Rosstat. The data collected from the survey underwent a weighting procedure. A database was created in MS Excel format based on the respondents' answers.Conclusion. The structure and data collection methods used to assess the implementation of national tobacco control policies in 12 Russian Federation regions provide results that are highly representative of the opinions of current and former smoker/ENDS users across all age and sex groups in urban and rural areas regarding the implementation of tobacco and nicotine control policies in the Russian Federation.

Background. Limited sensitivity and specificity of existing prostate cancer (PCa) diagnosis methods drive the search for new markers. A number of studies has demonstrated the potential for measuring expression of certain microRNAs in urine.Aim. To evaluate the diagnostic potential of measuring microRNA expression in urine in PCa.Materials and methods. A collection of urine sediment samples from 19 patients with benign prostatic hyperplasia and 44 patients with PCa was analyzed. RNA was isolated using the miRNEasy Serum/Plasma Kit. 16 µL of RNA isolated from each sample were converted into cDNA, which served as a template for real-time polymerase chain reaction. For sequencing, microRNA libraries were prepared using MGIEasy Small RNA Library Prep Kit v.2.0. The formed DNA nanoballs were placed into an MGI DNBSEQ-G400 sequencer. Sequencing results were processed using IsoMiRmap. Differences in microRNA abundance were analyzed using DESeq2. For miRNA-21, high-throughput sequencing data were corroborated by the results of quantitative real-time polymerase chain reaction.Results. 1154 types of microRNA were identified, 11 were differentially represented in all comparison groups. The most significant differences in cell sediment between benign prostatic hyperplasia and PCa patients were recorded for miR-451a (area under the curve (AUC) 0.98). Additionally, the abundance levels of two microRNA isoforms were significantly different: hsa-miR-144-3p|-1 (AUC 0.96) and hsa-miR-21-5p|+4 (AUC 0.68).Сonclusion. This study confirms that altered expression of microRNAs miR-21, miR-451a and miR-144-3p is associated with PCa, can be detected in urine samples, and can also be a potential non-invasive diagnostic criterion.

Background. Analyzing the sensitivity of patient-derived tumor organoids to anti-cancer medications shows great potential for tailoring personalized treatment plans.Aim. To obtain two prostate tumor organoid cultures, optimize the composition of culture medium, and to evaluatethe efficacy of the chemotherapeutic drug docetaxel using the obtained organoid cultures.Materials and methods. The initial tissue was dissociated using the gentleMACS Octo homogenizer. The obtained cells were cultured in Matrigel with different culture media for selection of the optimal one. Cell viability and growth rates were assessed using the MTS assay.Results. In this study, we successfully obtained two organoid cultures of prostate cancer cells and identified the most effective composition of culture medium. Using a cytotoxic test, it was shown that the obtained organoid cultures of prostate cancer cells had different sensitivity to docetaxel which was reflected in different inhibition of the tumor cell growth rate.Conclusion. The utilization of prostate cancer organoids to determine the best treatment approach is a highly promising experimental technology. Nevertheless, additional research is required before integration of this technology into clinical practice.
