Carl Stumpf and the Curious Incident of Music in Wittgenstein’s
Tractatus
Authors: Guter Eran
Published: January 2024

This essay explores Wittgenstein’s encounter with Stumpf’s work in Tone Psychology during a rarely studied period in Wittgenstein’s early career when he worked as a researcher in Myers’s laboratory for experimental psychology in Cambridge. I argue that Stumpf’s emphasis on the notion of musicality as the ability to characterize what is ‘musical’ about music troubled Wittgenstein’s initial formulation of his career-long adherence to the comparison between language and music. In the Tractatus the importance of internal projective relations far exceeds that of arbitrariness in language. This results in the curious elision of musicality in the Tractatus, as shown in his gramophone analogy. The acknowledgment of the enormous complexity pertaining to the facts of human life remained underdeveloped in Wittgenstein’s philosophy until the anthropological turn in his middle-period. Only then do we see the blooming of the language-as-music simile and its eventual impact on Wittgenstein’s later philosophy.

Published: January 2024

The objective of this study is to explore the feasibility of developing environmentally friendly green roller-compacted concrete (RCC) by utilizing locally available materials. The research investigates the behavior of RCC properties when different amounts of solid waste materials (brick powder, glass powder, and steel slag) are added as substitutes for cement content. To accomplish this, four laboratory tests were conducted: compressive strength, flexural strength, X-ray diffraction analysis, and scanning electron microscope imaging. These tests aimed to identify the changes in concrete properties resulting from the inclusion of waste construction materials as cement replacements. The study employed an approach that involved adding waste materials to the concrete mixture, with replacement percentages ranging from 10.0 to 40.0% in increments of 10.0%. Consequently, 12 concrete mixtures were prepared to examine the effects of adding waste materials (10.0–40.0%) as substitutes for cement content. In addition, one reference mixture was designed without any inclusion of waste materials for comparison purposes. In general, the results indicate that as the percentage of waste construction materials increases in the mixtures, there is a corresponding decrease in compressive strength. However, it is noteworthy that the strength activity index (SAI) exceeded 75% according to ASTM C618 standards. This indicates that the waste construction materials possess pozzolanic properties, making them suitable for use as cement replacements in RCC mixtures.
Exploring plasmonic gradient metasurfaces for enhanced optical sensing in the visible spectrum
Authors: Huang Shih-Hsiu , Wu Pin Chieh
Published: January 2024

While conventional optical sensors hold historical significance, they face inherent limitations in sensitivity, operational intricacies, and bulky size. A breakthrough in this realm comes from the advent of metasurface sensors, which leverage nanoscale optical effects, thereby expanding the horizons of optical sensing applications. However, past methods employed in metasurface sensors predominantly rely on wavelength shifts or intensity changes with high-Q resonances, thereby significantly restricting the detection bandwidth. In response to these challenges, this study introduces a plasmonic gradient metasurface-based sensor (PGMS) designed for refractive index detection across a wide wavelength spectrum. Through the utilization of the Pancharatnam–Berry phase method, the PGMS achieves a distinctive 2π phase shift, facilitating the simultaneous generation of specular and deflected beams. The introduction of a far-field intensity ratio (I* = I
+1/I
0) amplifies the change in optical response by maximizing the deflected beam’s intensity while minimizing specular reflection. Experimental validation attests to the PGMS’s consistent performance across diverse media and wavelengths, successfully overcoming challenges associated with oxidation issues. Furthermore, the incorporation of a normalization factor enhances the PGMS’s sensing performance and versatility for broadband optical sensing, accommodating variations in the refractive index. Particularly sensitive in green wavelengths, the PGMS demonstrates its potential in visible spectrum applications, such as biomedical diagnostics and environmental monitoring. This research not only addresses challenges posed by conventional sensors but also propels optical sensing technologies into a realm of heightened sensitivity and adaptability.

The article concerns the use of emojis and emoticons by teachers in the classroom and was written to draw attention to the educational use of these signs and symbols and to encourage wider possibilities of using them in education. In the first part of the text, considerations will be presented on the importance of emojis and emoticons in modern communication and the origins of the appearance of these characters in our society. In the second part, the results of a research survey conducted among teachers and students at Kielce schools and their parents in 2022 will be presented. An element of the research reconnaissance was also the analysis of websites devoted to emojis and emoticons used in the school classroom. In the last part of the article, conclusions will be presented that teachers most often use emojis and emoticons for educational tasks, as an element of assessment, as an “addition” to the assessment, as a separate assessment and a reward for completing the task and or a motivational element. Emojis and emoticons are mainly used in early childhood education, as they are positively received by younger students. Older students reserve these symbols rather for their peers, gradually distance themselves from the older generation (to which the teachers belong) and mock attempts by teachers to introduce these elements in the older classes. Parents mostly understand the use of these signs by teachers in the classroom. However, there are those who criticize the possibility of their use in schools.
Ontologiczne i epistemologiczne implikacje zanegowania zasad bytu i myślenia we współczesnym obrazie świata
Authors:   Archidiecezjalne Wyższe Seminarium Duchowne w Białymstoku, Matan Adam
Published: January 2024

One of the significant factors enabling the development of sciences was the conceptualization of fundamental principles of being and thinking, which was already achieved in ancient times. The principles of identity, non-contradiction, excluded middle, and causality became the foundations of emerging natural sciences in the 17th century. Simultaneously, in modern philosophy, they became the subject of critical analysis, resulting in their gradual rejection. Consequently, the concepts of being and knowledge were deprived of last-ing foundations. This made it impossible to meaningfully legitimize concepts such as truth, goodness, and beauty. As a result, skepticism and relativism destabilize the contemporary worldview. If we aim for a stable worldview, we should treat the principles of being and thinking as rules for verifying and falsifying our beliefs.

Developing the Framework for a Green Constitution: Strengthening Environmental Protection Initiatives in Indonesia
Authors: Hakim Rianta Muhammad , Imron Pradnya Kayla Ali
Published: January 2024

The current global environmental crisis occurs due to various factors, such as failed policies, destructive technologies, and lack of political commitment. To address these issues, the green constitution approach has emerged as an effective solution. However, Indonesia has not fully implemented the concept of a green constitution. This research uses a normative legal research method with comparative, conceptual, and statutory approaches. Data is obtained from a literature study of national and international regulations, books, articles, and scientific journals. Through a comparative study with Ecuador and France, the results show that Indonesia has the potential to integrate environmental principles that have been integrated into the constitutions of these countries. Ecuador, often referred to as "The Real Green Constitution," explicitly recognizes the rights of nature and regulates preventive measures against environmental damage. In France, the Environmental Charter has been integrated into the constitution, affirming the need for wise management of the environment and a balance between protection and utilization of natural resources. Indonesia can learn from these two countries in applying the concept of a green constitution and integrating environmental principles into its constitution in order to strengthen environmental protection, promote sustainable development, and help address the impacts of climate change. The resulting recommendation is an amendment to the constitution to further incorporate environmental principles as part of the main elements in the constitution.

Published: January 2024

Protean careers are understood and measured using different concepts. Apart from being confusing, it also causes divergences that result in limited operationalization of the protean career. O This study aims to develop a more comprehensive tool for measuring protean careers by examining the nomological network of ‘new’ protean career attitudes. Researchers added a measure of the affective component of love for work, in addition to dimensions driven by self-values and self-directed behavior. The results of the construct validity test through a nomological network involving 160 respondents showed two critical points. First, on the relationship between the dimensions, the dimensions of love for work and self-direction behavior are related to the harmonious passion variable and the proactive work behavior of career initiatives and personal initiatives. Second, the relationship within the dimension shows that the dimensions of love for work, driven by self-values, and self-directed behavior are interrelated. Additional validity tests, such as convergent, discriminant, and predictive validity tests, indicate that the question items are valid. Future research needs to pay more attention to the affective dimensions of love for work and harmonious passion.e.

Somatostatin receptors and the associated intracellular machinery: the two sides of the coin
Authors: Campana Claudia , Iyer Anand M , Ferone Diego , Gatto Federico , Hofland Leo J
Published: January 2024

Somatostatin receptors (SSTs) are widely expressed in pituitary tumors and neuroendocrine neoplasms (NENs) of different origins, i.e. the gastrointestinal tract and the thorax (lungs and thymus), thus representing a well-established target for medical treatment with SST ligands (SRLs). However, the response to SRLs is highly heterogeneous between tumors. Two main factors can contribute to this variability: (i) the differential SST expression among tumor types and (ii) the differential expression/modulation of the SST-related intracellular machinery. In this literature review, we provide an overview of available data on the variable expression of SSTs in pituitary tumors and NENs, together with the resulting clinical implications. Moreover, we aim to describe the complex intracellular machinery involved in SST signaling and trafficking. Particularly, we will focus on β-arrestins and describe their role in receptor internalization and recycling, as well as the various functions of these scaffold molecules in tumor pathogenesis and progression. This review highlights the interplay between membrane receptors and intracellular machinery, together with its role in determining the clinical behavior of the tumor and the response to treatment in patients with pituitary tumors or NENs.

Published: January 2024

The cruise control system regulates the car's speed, focusing on simulating and assessing the air compressor's speed control within the engine speed control system. Comprising a microcontroller PIC30 main board, H-Bridge DC motor drive board, encoder, 12V DC motor, supercharger, and PC interface with MATLAB and Simulink, the system aims for efficient speed control. Simulation results showcase the impact on DC electric motor speed control, emphasizing clarity and stability. The study outlines distinct outcomes: 1) Deactivation of the control system. 2) Activation at 1100 rpm. 3) Operation at 1200 rpm. 4) Functioning at 1400 rpm. Observations reveal that without the air compressor, the system struggles to control rotational speed. Conversely, with the control system engaged, consistent average errors of 0.63% occur across the three specified speeds. The setting time remains under 2 seconds. Subsequently, the control system autonomously readjusts the speed to the predefined specifications. The research highlights the system's effectiveness in achieving stable speed control, offering insights into its practical application within automotive engineering.

Authors: Šilinskas Gintautas , Raižienė Saulė
Published: January 2024

This cross-sectional study investigated correlations between six types of work motivation (intrinsic motivation; integrated, identified, introjected, and external regulation; and amotivation), teaching quality, and well-being among primary school teachers. Forty Grade 3 teachers in Lithuania answered a questionnaire about their work motivation (six types), teaching quality (frequency of instruction and degree of affection), and well-being (self-efficacy and exhaustion). Concerning teaching quality, the results showed that both autonomous motivation (intrinsic motivation and integrated and identified regulation) and controlled motivation (introjected and external regulation) positively correlated with teachers’ frequency of literacy and math instruction, whereas only autonomous motivation positively correlated with teachers’ affection when interacting with their class. Regarding well-being, autonomous motivation positively correlated with self-efficacy, whereas amotivation positively correlated with exhaustion.
Nonlinear mathematical model of pressure measurement systems in gas-liquid media
Authors: Velmisov Petr A. , Tamarova Yuliya A.
Published: January 2024

The primary element of the instrumentation for measuring the pressure of a gas-liquid medium is a sensor that supplies data on the pressure of the working medium. It determines the proper functioning of machines, mechanisms, and systems. Increasing the service life, reducing development time, and reducing the cost of sensors is one of the important tasks. Mathematical modeling of pressure measurement systems’ functioning plays an important role at the design stage of such systems. This article examines a nonlinear one-dimensional model of a mechanical system “pipeline – pressure sensor” designed to measure and control the pressure of the working gas-liquid medium in the combustion chambers of engines. In such a system, the sensor is connected to the engine via a pipeline and is located at some distance from it to reduce the impact of vibration accelerations and high temperatures. The purpose of the work is to study the dynamics and stability of joint oscillations of the elastic sensitive element in the pressure sensor and of the working medium in the pipeline for a given law of pressure change in the combustion chamber. The study is provided under the assumption that the working medium is ideal and compressible. To describe the movement of the working medium (gas or liquid), a nonlinear model of fluid and gas mechanics is used. Mathematical description of the process of interest includes an initial boundary value problem, whose formulation contains a nonlinear partial differential equation. To solve it, numerical-analytical method of solution based on the Galerkin method is proposed, which makes it possible to reduce the study of the problem to solving a system of ordinary differential equations. A numerical experiment is carried out and examples of calculating the dynamics of the sensor's sensitive element are presented. The proposed mathematical model makes it possible to determine the law of change in the deviation of the sensor's sensitive element depending on the law of change in pressure in the combustion chamber. The research results are intended for use at the design stage of pressure measurement systems.

W niniejszym artykule zostały przybliżone zagadnienia związane z problemem unifikacji i kodyfikacji polskiego prawa spadkowego po 1918 roku, na przykładzie zasad odpowiedzialności za długi spadkowe. Do wybuchu II wojny światowej nie przedstawiono jednak jednolitego projektu prawa spadkowego, a prace specjalnej podkomisji nie wyszły poza dyskusję nad podstawowymi założeniami spadkobrania. Spory ideologiczne dotyczące osobowego prawa małżeńskiego przyniosły wiele problemów i przełożyły się na postęp prac w zakresie unifikacji prawa spadkowego. W konsekwencji nie udało się dokonać kompleksowej unifikacji i kodyfikacji prawa spadkowego w okresie drugiej Rzeczypospolitej. Unifikację prawa spadkowego wznowiono dopiero po II wojnie światowej, a ostatecznie zakończyła się w roku 1946 wydaniem dekretów o prawie spadkowym oraz postępowaniu spadkowym. Zaś w roku 1964 prawo spadkowe zostało skodyfikowane w księdze czwartej kodeksu cywilnego. Do czasu unifikacji prawa spadkowego w 1946 roku obowiązywały regulacje zawarte w ABGB, Kodeksie Napoleona oraz BGB, także w zakresie zasad odpowiedzialności za długi spadkowe. Wprowadzenie do polskiego prawa spadkowego, w tym także w odniesieniu do zasad odpowiedzialności spadkobierców za zobowiązania spadkowe, rozwiązań przyjętych w wielkich kodyfikacji cywilnych XIX wieku, pozwala na umieszczenie rozwiązań przyjętych w księdze czwartej kodeksu cywilnego w tradycji romanistycznej europejskiego prawa prywatnego.
Odpowiedzialność zawodowa ratowników medycznych
Authors: Wolska Joanna
Published: January 2024

Ratownicy medyczni doczekali się ustawy regulującej ich zawód. Ustawa z dnia 1 grudnia 2022 r. o zawodzie ratownika medycznego oraz samorządzie ratowników medycznych w przeważającej części wejdzie w życie po upływie 6 miesięcy od dnia ogłoszenia, a więc 22 czerwca 2023 r. Problematyka poddana analizie w niniejszym artykule, a więc uregulowana w rozdziale 7 ustawy, dotyczącym odpowiedzialności zawodowej ratowników medycznych, nie jest niczym nowym w polskim ustawodawstwie. Nowa regulacja opiera się na założeniach przyjętych już w ustawach traktujących o odpowiedzialności zawodowej lekarzy, fizjoterapeutów, pielęgniarek i położnych, które to regulacje służyły w niniejszej pracy za materiał porównawczy. Czy regulacje w takim kształcie są potrzebne także dla ratowników medycznych, którzy stykają się z pacjentem „na pierwszej linii frontu” przy zagrożeniu jego życia i zdrowia? Regulacje odpowiedzialności zawodowej powinny być uzupełnieniem regulacji karnych, cywilnych czy pracowniczych do zmotywowania osób wykonujących zawody medyczne do wykonywania swoich zadań w sposób bezpieczny dla pacjenta. Czy i w tym przypadku ustawodawca sprostał tym założeniom?
Impact of different ENSO positions and Indian Ocean Dipole events on Indonesian rainfall

The El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) are widely recognized as the leading modes of climate variability in the tropics. This paper investigates the impact of different ENSO positions and IOD events on Indonesian rainfall during the period 1950–2021. The ENSO position is determined by the largest value of four Niño indices: Niño 1+2, Niño 3, Niño 3.4, and Niño 4. These ENSO positions are hereafter referred to as  El-Niño/La-Niña 1+2, El-Niño/La-Niña 3, El-Niño/La-Niña 3.4, and El-Niño/La-Niña 4, respectively. The Dipole Mode Index (DMI) was used to observe IOD events. Different ENSO positions and IOD events result in different responses to Indonesian rainfall, obtained from the European Center for Medium-Range Weather Forecasts (ECMWF) ERA-5 data. The most significant decrease in rainfall occurs during the June-to-Septempber (JJAS) season of El-Niño 3. Conversely, during El-Niño 3.4, rainfall increases in the Sumatra and part of Kalimantan regions. The most significant increase in rainfall occurs during La-Niña 3.4, followed by La-Niña 4, La-Niña 3, and La-Niña 1+2. During a positive IOD phase, the southern part of western Indonesia experiences a decrease in precipitation of more than 30%. A more significant decrease in rainfall (>40%) occurs when a positive IOD co-occurs with El-Niño. During a negative IOD phase, Indonesia's rainfall patterns become more spatially variable. An increase in rainfall is more pronounced when a negative IOD co-occurs with La-Niña. The difference in Indonesian rainfall during different ENSO positions and IOD phases is related to differences in atmosphere-ocean interaction during each condition.

A search for new approaches to sulfurous waste utilization is one of the urgent tasks of chemical technology. Thiol-disulfide exchange reaction (TDE) is one of the possible ways to involve technogenic wastes in organic synthesis. Electricity can promote such type of interactions. In this paper, we have studied TDE reactions involving low molecular weight thiols or their dimers under electrochemical conditions. The exchange processes were examined using the model reaction between 1-propanethiol and phenyl disulfide. Electrolysis was performed in the presence of redox mediators such as arylphosphines, substituted amines, o-, p-aminophenols or catechol. These compounds can initiate a TDE process with a formation of unsymmetrical disulfides. 4-Amino-2,6-diphenylphenol was chosen as the most effective redox mediator, which reduces the anodic overvoltage of a thiol oxidation by 1.20 V. The advantage of electrolysis in an undivided cell is the increased yield of target unsymmetrical disulfides due to the possibility of reduction ofhomodimers at the cathode. The involvement of refining waste, such as C3–C4 disulfide oil, in the reaction with substituted thiophenols made it possible to obtain a number of unsymmetrical arylalkyl disulfides with biologically active fragments in a high yield (up to 97%) under indirect electrolysis conditions.
On the issue of optimizing snow crab fishing in the Gulf of Shelikhov, the Sea of Okhotsk
Authors: Shaginyan E. R.
Published: January 2024

Existance of commercial snow crab aggregations for target fishing has been discovered in the Gulf of Shelikhov, the Sea of Okhotsk, based on the survey data for 2014 and 2021–2022. Sites of higher densities of snow crab have been figured. Analysis of sex ratio and size composition of the catches was made, and the catch values per an fishing effort and stock abundance of commercial males were estimated. In order to involve mentioned snow crab stock of the Gulf of Shelikhov, a ban for the fishing of snow crab has been recommended in the West Kamchatka subzone southward from 59°15´ N.
Feeding and trophic interactions of plankton Crustaceans in the pelagic zone of the Azabachye Lake
Authors: Bazarkina L. A.
Published: January 2024

Characteristics of feeding mechanisms, forage composition and methods of analysis of the diet of plankton crustacean are demonstrated based on reviewed and author’s data. Preferable forage species for the mass plankton crustaceans Cyclops scutifer and Daphnia galeata in the lake Azabachye were figured out using methods of population ecology. It is revealed, that reproduction of the cyclops and daphnia populations prospers due to Aulacoseira subarctica. In the periods of poor vegetation of the diatom the cyclops have been feeding on shell-less rotifers, and in particular years – on the diatoms of the genera Stephanodiscus. In the years of vigorous bloom of  Bacillariophyta the daphnias filter small cells of diatom (S. minutulus) or blue-green (Gloeocapsa sp.) algae. In case of suggested similarity in the forage organisms between small numbered Eurytemora kurenkovi and abundant C. scutifer, there was no competition observed between the copepods. The main forage component for predator Leptodora kindti was juvenile D. galeata. It is concluded based on the analysis, that intense competition between plankton crustaceans does not raise in the Azabachye Lake.
