The “cry” of a nightingale. Expression, emotion, meaning
Authors: Żerańska-Kominek Sławomira
Published: August 2024

Birdsong is among the most beautiful and complex sounds produced in the natural world. Modern ornithological research into the vocal communication of birds continues to open up new fields of research in neurobiology, ethology and evolutionary biology. Birdsong also fascinates musicographers and musicologists interested in, on the one hand, the presence of birds in music, and, on the other — theoretical questions concerning the ontology, aesthetic qualities and semiotics of birdsong resembling music in some respects. Reflection on this direct, easily accessible and natural sound experience of human beings is the subject of the present article. It is an attempt to answer the question about the source of expression and aesthetic meaning of bird-song for humans, about how bird “music” resonates with the human world. In particular — about whether the expressive meaning of birdsong is embedded and contained in it or whether its source is the listener’s subjective projection.

Authors: Boudnani Zeine Elabidine , Bachir Glaoui , M’hamed Merbouh
Published: August 2024

The objective of this study was to evaluate and characterize the performance of ground tire rubber (GTR) modified dense graded asphalt mixtures to recommend a suitable GTR content to produce a mix that provides superior pavement performance characteristics. The research effort encompassed investigation of stiffness and cracking resistance of six dense graded asphalt mixtures, including one conventional and five modified mixes covering 42 samples. Addition of GTR using wet process showed decrease in stiffness during loading. Cracking resistance of GTR modified mixtures increased with higher levels of dosages regardless of the base binder. An increase in the GTR dosage from 0 to 10% did not result in a significant change in fracture energy but a further increment to 25% increased the fracture energy. The laboratory Results indicated that 10% GTR was showed as the optimal content for the stiffness modulus and 25 % GTR as better content that provides better cracking resistance.

Published: August 2024

The circular economy and the principles by which it is guided, has become the subject of more and more scientific works, the authors defining this green part of consumerism in multiple and diverse ways, but all focusing on the decision-making power of consumers and producers regarding the consumption of goods and services, respectively of the practical measures to maximize the recycling and reuse of the resulting waste. This research follows the evolution of the impact of the human factor on the environment at the level of Romania in the period 1948-2024, of the European Union, Switzerland, Norway and Iceland (UEFTA-Liechtenstein) in the period 2010-2022, respectively 2004 - 2021. The main purpose of the article is to to determine the economic behavior models of the main actors on the global market, regarding the circular economy, with the aim of understanding their motivations and obviously to recommend the changes in mentality and implicitly the reactions, respectively the actions perceived to be strictly necessary for a sustainable use of raw materials and materials used in production processes. Of course, the concept of circular economy is one of vital importance for the entire human society, especially in the conditions of the demographic explosion predicted in the foreseeable future. For multiple reasons, this concept is absolutely decisive for avoiding the economic, social and ecological collapse of the entire planet we live on. The fundamental question we want to answer is “What are the main behaviors of consumers and producers regarding the circular economy?”, in order to be able to determine the current motivations, possibly future forecast and rewards that prove beneficial in the implementation of the principles of the green economy. The study is based on data related to GDP/capita, the recycling rate, the amount of greenhouse gases emitted and the number of vehicles with alternative propulsion.
Dynamic Behavior of Railway Bridges Under High-Speed Traffic Loads
Authors: Iordan Petrescu , Mihaela Stan Oana , Marian Stănescu Răzvan
Published: August 2024

The interest on the dynamic behavior of railway bridges has grown in recent years due to the emergence of high-speed trains that induce a significant dynamic effect. A correct understanding of the dynamic behavior of a railway bridge is essential, as an accurate prediction of the structure’s response contributes to cost-effective design for new bridges and rational operation of existing ones.

The objective of this study was to investigate the dynamic behavior of an existing single-track railway bridge under dynamic traffic loads. For this study, it was assumed that the bridge is traversed by a high-speed train traffic with different speeds, ranging from a minimum speed of 100 km/h to a maximum of 300 km/h.

Moving vehicles, represented by Eurocode LM 71 and HSLM-A1 models, are simulated using constant intensity forces at the wheel locations, moving across the bridge at a constant speed. Dynamic interactions between the vehicle and the bridge, as well as track irregularities, are not considered.

To illustrate the variation of the dynamic amplification factor during the passage of the convoy at different speeds, a 3D dynamic model of the bridge structure was created, and dynamic analysis was performed using the modal superposition method.

The paper presents variations in displacements, accelerations, and the dynamic amplification factor determined through dynamic analysis for different elements of the bridge structure, depending on the speed of the moving forces. The numerical resonance speed, significantly amplifying the bridge structure’s response, was identified.

Published: August 2024

Strategy and Performance Management has evolved in the last decades to become a critical capability adopted and nurtured by more and more organizations worldwide. While several types of performance management architectures are set in place to facilitate strategy execution and performance excellence within organizations, less emphasis is attributed to understanding how well performance management tools, processes, and resources are set to enable proper integration and allow the maturity of such architectures. To address this gap, this research focuses on developing and applying an Integrated Performance Management Maturity Model that can test the dynamics of performance management architectures. Using a structured research protocol, 5 public organizations from different sectors in Saudi Arabia were chosen to test the impact of the maturity model designed and diagnose their maturity level. Results from the study suggest moderate to advanced performance management practices among governmental. The application of the maturity model assessment allowed a diagnosis of performance management architectures’ status quo while enabling the development of improvement roadmaps for the entities included in the study.
Predictors of Consumer Aggression Toward Inclusive Brands: A Mixed Methods Investigation
Authors: Hajisafi Amir
Published: August 2024

This mixed-methods study investigates aggressive consumer reactions toward inclusive brands. An online survey of 384 U.S. consumers and 20 in-depth interviews reveal that virtue signaling, moral outrage, and tribalism predict consumer aggression through boycotts and negative publicity. Virtue signaling exhibits the strongest effect, suggesting consumers’ desire to demonstrate moral virtue drives reactions most strongly. The theoretical implications indicate that single theories provide limited explanations; integrating complementary perspectives generates richer insights. Practically, empowerment-based strategies promoting dialogic communication, transparency, and stakeholder co-creation may minimize outrage and hostility while advancing inclusivity. Recognizing consumers’ diverse motives allows tailored engagement to transform aggression into constructive dialogue, thereby advancing social good as the brands’ ultimate purpose.

Towards a Contemporary Canadian Jewish Pedagogy of Listening
Authors: Goren Seth W.
Published: August 2024

Listening as a field is relatively new, with little research into the teaching of listening or Jewish conceptualizations of listening. A Canadian Jewish framework for teaching listening can provide pathways towards healing from trauma, amplifying diverse perspectives in the context of multiculturalism, and advancing reconciliation. Furthermore, developing and implementing a Canadian Jewish pedagogy of listening could equip teachers, students, and their communities to better thrive in challenging environments, engage across differences, and feel appreciated. If deployed widely, these approaches have the potential to make a substantial impact beyond the Canadian Jewish community, both nationally and in the field of listening as a whole, at a time of rising disagreement, adversity, and tension.
The Chinese economic policy in African markets: An essay based on evidence and perspectives
Authors: Scalamonti Francesco
Published: August 2024

This paper is an essay that aims to understand China's economic policy in the African markets. As a result, changes in international trade and foreign direct investments (FDIs) from the beginning of the new millennium and to the end of the last decade have been highlighted. The data have shown a clear intensification of Chinese trade and FDIs in African markets in 2017 compared to 2002. This international expansionism is a result of the economic policy adopted by China to gradually push firms to approach foreign markets. Therefore, it has been a consequence of the leading and supporting role of international trade played by Chinese governance.

The study aimed to investigate the demographic, social, and economic factors that affect the prevalence rates of marital violence against Palestinian women. The present study used survey data. The declaration of violence in Palestinian society was made in 2019 by the Palestinian Central Bureau of Statistics. The study sample consisted of 5,114 married women or formerly married women. In addition, the study used the descriptive approach to describe the demographic, social, and economic variables that affect the prevalence of marital violence against women (MVAW). Binary logistic regression was utilized to investigate the determinants of MVAW. The study concluded that young women are more susceptible to all forms of violence. An increase in the number of children in a family is correlated with higher rates of violence, and the women who are living in the Gaza Strip have elevated odds of experiencing MVAW if compared to women living in the West Bank. Women in low-income families are more susceptible to marital violence than women from affluent families. Currently, working women are less vulnerable to MVAW than their non-working counterparts. The study recommends further research and collaboration between government and non-government organizations to prevent the expansion of this problem.

The Neoplatonic Pursuit of God in the Middle Ages
Authors:   University of Tyumen (Russia), Alexandrov Emile
Published: August 2024

This paper studies the differing approaches to pursuing God during the Middle Ages to show the latent Neoplatonism inherent to four prominent thinkers from the Early to High Middle Ages. Beginning with Pseudo-Dionysius the Areopagite, God’s darkness is equated with an ineffable light. Pseudo-Dionysius used darkness to describe God exceeding the bounds of the intellect; a metaphor also used to illustrate the non-objectifying imperative for union with God. In union, Pseudo-Dionysius outlines an apophatic process concurrently with a ladder of ascent. Eriugena appropriates Pseudo- Dionysius’ darkness, albeit dialectically. In accepting the limitations of the intellect, Eriugena maps the boundaries of the intellect using binary oppositions between being and non-being and the created and uncreated. Eriugena concludes we can achieve union only by meditating upon God’s theophanies. By distinguishing reason from faith, we observe the turn to reason in Anselm. In signifying the start of the High Middle Ages, Anselm makes the unprecedented claim that God is proveable through reason alone, although such proof requires arduous contemplative work. Anselm nevertheless understood prayer and faith as prerequisites for pursuing God. Anselm’s view of the limitations of the intellect later becomes the backbone of his Ontological Argument, which Aquinas takes up and revises by focusing on Anselm’s definition of contemplation. For Aquinas, the non-objective vision of God, which he calls a beatific vision, is the ground for union with God. The very limitations of the intellect for Aquinas prove the need for beatific vision as the prerequisite for bridging the infinite gap between God and intellect. Throughout this investigation, we uncover the intrinsic Neoplatonism in the Middle Ages philosophers exhibited in their pursuit of God.
Epicurus on the Passions
Authors:   Institute of Philosophy and Law SB RAS, Novosibirsk, Russia, Brovkin Vladimir
Published: August 2024

The article deals with the question of Epicurus' attitude to the passions. It is established that the doctrine of passions plays an important role in the philosophy of Epicurus. It is shown that Epicurus sees the greatest danger to peace of mind in fears of the forces of nature, in love passion and greed. Therefore, these passions must be completely eliminated. Anger, according to Epicurus, should be restrained, because in some cases it can be natural. Epicurus approves of the pleasant sadness of remembering dead friends and compassion for loved ones. Epicurus also welcomes the joy and even rejoicing associated with spiritual goods. Thus, on the question of passions, Epicurus managed to develop a position that differs from both the Stoic doctrine of dispassion (apathy) and the peripatetic doctrine of moderation in passions (metriopathy).
Other and Nothing in Platonic apophatics: towards discussions about the dialogue «Parmenides» Language: Russian
Authors:   Minin Nizhny Novgorod State Pedagogical University (Minin University), Bogomolov Aleksey , Svetlov Roman ,   Immanuel Kant Baltic Federal University
Published: August 2024

The article is devoted to the problem of the correlation of apophatic issues in the dialogues "Sophist" and "Parmenides". The article substantiates the position that the doctrine of non-being, presented in the Sophist, is one of the foundations of the first two hypotheses of Parmenides. An important point in the Sophist is the distinction between the other (ἕτερον) and the nature of the other (θατέρου φύσιν), which serves as a prerequisite for the dialectic of the one and many in the second hypothesis. It is suggested that the other six hypotheses are determined by the understanding of the other in the Sophist
The Emergence of Individuality. Part Three
Authors:   I. Kant Baltic Federal University, Donskikh Oleg ,   Novosibirsk State University of Economic and Management (Russia)
Published: August 2024

The Persian Empire was formed in political and cultural unity only in the 6th century BC. The article examines the position of the individual as a subject of state-legal relations in the empire, which was in a sense the successor of Media, and where, unlike, for example, Egypt, society was quite poorly structured. Cyrus II, and after him Darius I directed their policy to position everyone towards loyalty to the king, and to dissociate other possible attachments. Therefore, the position of an aristocrat in society was determined by proximity to the king, and then by merit, family, etc., accordingly, there was a constant struggle to define and maintain his place. Darius I, on the one hand, relied on already existing laws and lists of precedents dating back to the heyday of Elam and Sumer, and, on the other hand, formulated the principles of his rule on the basis of Zoroastrianism. He proclaims himself the chosen one of Ahuramazda, and asserts the principles of social justice uniform for all strata of the population. To strengthen his power, Darius I supplements Zarathushtra's peculiar monotheism with the idea of the power of a single monarch over a multitude of lands, making certain changes in the traditional images. He strengthens the image of Ahuramazda by adopting the solar symbol as his attribute and by powerfully reinforcing the Indo-Iranian concept of khvarnah (king’s luck). Through this he legitimizes his right to the loyalty of the faithful and the punishment of the unfaithful. The significance of Zoroastrianism, adopted as the official religion of the Persians, was that each person had to accept the necessity of a constant personal choice between good and evil, between two spirits - the spirit of good and the spirit of evil. Within the legal system, Persian kings made a fundamental step from the religious ethics of Zoroastrianism to politics. Lye began to be understood not as a moral category, but as a negative force, always set up to destroy the established state order. Great importance was attached to the formation of ethical consciousness in schools, where justice was taught, forcing children to get used to reflect upon their consciousness evaluating their own behavior from a moral point of view.
Some Peculiarities of the Pagan Worship in the Christian Roman Empire (5th – 6th centuries)
Authors:   The Institute of World History of the Russian Academy of Sciences, Vedeshkin Mikhail ,   The School of Public Policy RANEPA
Published: August 2024

The study examines the nature of ritual practices adopted by the pagans of the late Roman Empire under the conditions of a complete legislative ban on all forms of traditional worship. Based on several reports about religious rites performed in the places, which were once occupied by pagan sanctuaries, it is argued that from the point of view of worshippers of the ancient gods the ruins and remnants of the decoration of their former shrines continued to retain religious significance even after their desacralisation. Moreover, idolaters continued to venerate the locations where the pagan cult had once taken place, even if these sites were occupied by Christian sanctuaries. Analyses of hagiographic accounts allow us to assert that pagans or crypto pagans visited Christian temples to offer prayers to the gods, and even attempted to perform ancient rituals in the sanctuaries of the new faith. Since the harsh anti-pagan legislation prevented them from revealing their motives for visiting churches, they averted suspicion of performing forbidden rites by pretending to appeal to the Christian God and His saints.
Hermeticism and Kabbalah. On the historical connection between Hermetic and Jewish mysticism
Authors:   Saint Petersburg State University, Afonasin Eugene ,   Immanuel Kant Baltic Federal University (Kaliningrad, Russia)
Published: August 2024

Hermes of Pico della Mirandola has nothing in common with the hero of the treatise Asclepius and the texts of the Hermetic Corpus. Pico's gaze is directed deep into the medieval Jewish and, eventually, Arabic tradition. More precisely, through the cabbalistic works, for the first time available to the bright representative of the Italian Renaissance, there came to life the fruits of another Renaissance, the Spanish Renaissance of Alfonso X de Castilla (1252–1284), while through the “Sabian” magic Hermeticism became an integral part of Jewish mystical philosophy. According to modern studies, by this time we can speak of the beginning of the synthesis of Kabbalah and Hermeticism in mystical Jewish philosophy (Idel 2003, 395 sq.). So one can now qualify Frances Yates's (1964) famous statement that only by the efforts of Pico della Mirandola that Hermeticism was “supplemented” by Kabbalah. To what extent than one can argue that the connection between Hermeticism and Kabbalah is not accidental, but prepared by contacts between Jewish philosophy and Hermeticism at the earliest stages of their formation, perhaps as early as the Hellenistic period? Such a connection is assumed by many authors, since, from the point of view of the internal criterion, we cannot be sure that all the textual inconsistencies in the treatises of the Hermetic corpus are necessarily later interpolations, much less the interventions of the later and practically oriented astrologer, as Ch. Wildberg (2013) believes, because there is nothing in them that could not have been written by a philosopher of the Hellenistic or Roman period. It is nevertheless clear that, originally being a mystical anthropological doctrine, Hermeticism steadily moved in an astrological direction, which made it attractive to the most diverse authors from antiquity to modern times, and one of the most enigmatic and colorful philosophers of the Italian Renaissance, Giovanni Pico della Mirandola, thought himself to be their successor.

Az alábbiakban egy olyan képet fogok bemutatni, ami az 1956-os forradalom és szabadságharc során készült, méghozzá a Szabadság téri szovjet hősi emlékmű megrongálása közben.1 A kép fekete-fehér, és egy, a Fortepannak adományozott hagyaték részét képezi, készítője ismeretlen.2 A fényképet magát több nézőpontból közelítem meg, ami leképezi a szövegem felépítését is. Elsődlegesen a helyszínnel kívánok foglalkozni, ugyanis a fényképen megörökített esemény nem értelmezhető a Szabadság tér összetett jelentéshálójának ismerete nélkül. Ezen rétegek megismerése végbemehet az idő és tér tekintetében lineárisan és vertikálisan egyaránt. A helyszín fókuszpontjában elhelyezkedő obeliszket nem tudjuk különválasztani a tér szimbolikus mezőjétől, azonban fizikailag leválasztható, tehát önmagában is értelmezhető. A Szabadság teret sokan tartják eufemisztikus elnevezésűnek, van, aki a „nemzeti tudathasadás” terének tartja.3 Az mindenesetre teljesen biztos, hogy a mindenkori hatalom emlékezetpolitikájának egy kedvelt színhelyéről beszélhetünk, az elnyomás és a szabadság ellentétes jelentéséből fakadóan paradox, Foucault fogalmával élve, heterotopikus hely.

Authors: Nahak Andre Marce , Khwee Kho Hie , Danial Danial
Published: August 2024

The number of blades and helix range in the helical turbine are considered as internal parameters, while the outer radius of the turbine, turbine length, and turbine shaft inclination are regarded as external parameters. Both of these parameters define the geometric characteristics of the helical turbine. The geometric configuration of the Archimedes turbine can be determined using the formulation by Chris Rorres. The designed prototype of the Archimedes turbine has the following specifications: a total of 3 blades (N), an inner diameter (Di) of 11.4 cm, an outer diameter (Do) of 21.28 cm, a turbine length (L) of 80 cm, a screw pitch (Λ) of 25.53 cm, a number of turns (Z) of 3, and a turbine weight of 10.80 kg, with a turbine shaft inclination angle of 30°. From the research findings, the highest turbine performance was achieved at a water discharge of 0.006 m^3/s, resulting in a generated voltage of 41.02 V with a turbine rotation speed of 309.3 rpm.In this research, the experimental method was used, which involved testing the turbine performance by varying the water discharge under both unloaded and loaded conditions (load simulated using a lamp). Throughout the research process, each test data was recorded and analyzed using relevant formulas, and the results were presented in the form of graphs to facilitate drawing conclusions. From the research findings, the best turbine voltage regulation occurred at a water discharge of 0.0026 m^3/s, resulting in a voltage regulation of 22.38%.

Indonesia possesses a substantial potential in renewable energy resources, one of which emanates from waste. Palm oil waste biomass stands as a viable energy source, aligned with the escalating adoption of renewable energy in the country, as outlined in the national 2025 primary energy mix targets, which emphasize augmenting biomass utilization as an energy source. The artificial drying process of oil palm empty fruit bunches utilizing an electric drying apparatus at a temperature of 150°C, for durations of 10 and 20 minutes, is geared towards achieving low moisture content and enhanced calorific value of dried empty fruit bunches, rendering them efficient for employment as feedstock in Power Plants. Based on the findings of the 10-minute drying study, a moisture content of 7.88% was attained, in adherence to the Indonesian National Standard (SNI) 01-6235-2000 stipulating 8%. Additionally, the calorific value registered at 4353 kcal/kg. The constructed drying mechanism yielded electricity costs of Rp. 563,433 for a 10-minute drying session each 1 kg sample and Rp. 924,636894 for a 20-minute drying cycle each identical sample weight.

Published: August 2024

This study aims to analyze and design an effective Solar Power Plant (PLTS) in Sambas Regency using the spatial data-based Weighted Overlay method. Sambas Regency, located in the 3T (Disadvantaged, Frontier, Outermost) area and directly bordering Malaysia, faces the challenges of uneven electricity distribution and the growth of energy demand that continues to increase along with population growth. With significant renewable energy potential in West Kalimantan, especially solar energy reaching 20 GW, this research has high relevance in providing sustainable solutions to support the region's energy needs. A GIS-based Weighted Overlay approach is used to determine the optimal location of PLTS by considering various parameters such as NDVI, NDBI, NDMI, LST, Slope, Rainfall, distance to PLN substation, and existing PLTS location points. The results of this mapping and analysis were then integrated into the technical design of the PLTS using PVSyst software. This research successfully overcomes practical obstacles, such as land protected by the Ministry of Environment and Forestry, by providing detailed solutions that can be implemented. With the continuous growth of energy demand in Sambas Regency, the implementation of utility-scale solar power plants is becoming increasingly urgent. Through economic analysis that includes NPV, PI, IRR, and DPP, this investment can be concluded as feasible. With the application of the right methodology, it is hoped that this research will make a real contribution in supporting Indonesia's efforts to achieve carbon-neutral targets and meet energy needs in border areas that are still unelectrified.

Published: August 2024

Pathologies in adipose (fat) tissue function are linked with human diseases such as diabetes, obesity, metabolic syndrome, and cancer. Dynamic, rapid release of metabolites has been observed in adipocyte cells and tissue, yet higher temporal resolution is needed to adequately study this process. In this work, a microfluidic device with precise and regular valve-automated droplet sampling, termed a microfluidic analog-to-digital converter (µADC), was used to sample secretions from ~0.75 mm diameter adipose explants from mice, and on-chip salt water electrodes were used to merge sampled droplets with reagent droplets from two different fluorometric coupled enzyme assays. By integrating sampling and assays on-chip, either glycerol or non-esterified fatty acids (NEFA), or both, were quantified optically within merged 12-nanoliter droplets using a fluorescence microscope with as high as 20-second temporal resolution. Limits of detection were 6 µM for glycerol (70 fmol) and 0.9 µM for NEFA (10 fmol). Multiple ex vivo adipose tissue explants were analyzed with this system, all showing clear increases in lipolytic function after switching from feeding to fasting conditions. Enabled by high temporal resolution, lipolytic oscillations of both glycerol and NEFA were observed for the first time in the range of 0.2 to 1.6 min-1. Continuous wavelet transform (CWT) spectrograms and burst analyses (0.1 to 4.0 pmol bursts) revealed complex dynamics, with multiplexed assays (duplex for glycerol and NEFA) from the same explants showing mostly discordant bursts. These data support separate mechanisms of NEFA and glycerol release, although the connection to intracellular metabolic oscillations remains unknown. Overall, this novel device allowed automated and highly precise temporal sampling of tissue explants at high resolution and programmable downstream merging with multiple assay reagents, revealing unique biological information. Such device features should be applicable to various other tissue or spheroid types and to other assay formats.

Why Aotearoa New Zealand Needs a Corporate Homicide Bill
Authors: Belich Camilla
Published: August 2024

New Zealand needs a law to make corporate homicide a crime. Without such a law those primarily responsible for the protection of workers and others from death or serious harm due to work do not face full responsibility for their actions or inactions. In other words, there may be no justice for people killed or needlessly injured due to work. This is why I propose a member’s Bill, the Crimes (Corporate Homicide) Amendment Bill, which would introduce a new offence of corporate homicide.
