Published: June 2024

School has become more project-oriented. There is tremendous potential for student agency here. Children's agency can be revealed through a participatory approach to childhood sociology. The analysis model is based on the principles of participatory methodology and interpretive reproduction by Corsaro. Three groups of variables are identified: the subjectivity of the child, the balance of power between the child and the adult, and the joint creativity of the participants. The empirical basis of the study is the “Green School” case, implemented online with the participation of five schoolchildren and one teacher from the Khabarovsk Territory. Observation, interviews, focus groups, and text analysis were used for the monographic analysis of the “case”. In a space of “equal participation”, where students and a teacher are co-participants and co-researchers, children’s agency can be disclosed. Children maximally expresses themselves through free choice, gaining personal experience in the process of making decisions. Responsibility arises not as an “obligation”, but as a motivation for learning: “how can we do it to make it better”. The results of this work can be used by educators in organizing project-based research activities for students, utilizing sociological methods adapted to the study of children.
LIVE ACTION ROLE PLAY AS A SOCIAL-PSYCHOLOGICAL PHENOMENON
Authors:   Russian State University for the Humanities, Solodnikova Nadezhda.V.
Published: June 2024

The study data shows that LARP players in Russia are getting older and the number of women among them increases. Russian LARPers participate in it for 5–14 years which is on average longer than Americans do (Swedes have even more experience, though). From the point of view of expenses and income LARP is considered to be more like a form of volunteering for the team’s masters. Money on LARP are earned primarily by businesses that are not directly involved in it, but are close enough to the game process (e. g., hotels as venues, tailoring studios that can create clothes, shoes, décor, etc.). A rather new feature for LARP in Russia is the participation of state in the funding – for now that concerns mainly LARPs for teenagers. The main motive for participation among Russians is the wish to experience situations that they will not face in real life. American LARPers value the opportunity to spend time with friends, while Swedes love the feeling of living in another reality.
PSYCHOLOGICAL CHARACTERISTICS OF PEOPLE WITH DIFFERENT PREFERENCES FOR VIRTUAL SPACE IN 2021 AND 2023
Authors:   Russian State University for the Humanities, Philippova Ol’ga S.
Published: June 2024

The article presents a comparative analysis of the psychological characteristics of people with different preferences for virtual space in 2021 and 2023. The study involved 351 respondents aged 17 to 35 years. The following scales were used: General Problematic Internet Use Scale (GPIUS3), Five-Factor Mindfulness Questionnaire (FFMQ), Psychological Well-Being Scale. The results showed that, in general, the group of respondents in 2023, compared with respondents in 2021, is less likely to choose online communication; have fewer negative consequences of Internet use that affect everyday life; have a great sense of personal development. The difference in psychological characteristics between subgroups of people who prefer real interaction with the world and a combination of real and virtual interaction with the world in 2023 is practically absent and is characterized only by a greater sense of personal progress among the latter. The situation in 2021 is the opposite; people who prefer real interaction with the world demonstrate a higher level of well-being and less pronounced factors of problematic Internet use. Respondents who prefer a combination of real and virtual interactions with the world in 2023 feel more favorably, and their use of virtual reality is more adaptive. Respondents who prefer a virtual form of interaction with the world in 2023 have significant differences in psychological characteristics, both in comparison with other respondents in the 2023 sample, and with a subgroup with a similar preference for virtual interaction in 2021. They also have significantly lower levels of psychological well-being.

POST-TRUTH AS A THREAT TO MEDIA SAFETY IN THE CONTEXT OF DIGITAL TRANSFORMATION
Authors:   Russian State University for the Humanities, Nerents Daria V.
Published: June 2024

One of the consequences of the modern system of information exchange, which includes both centralized (mass media) and distributed (social networks) sources of information, is the development of manipulative techniques of the public opinion formation, the totality of which, together with the fake content that has become commonplace, is called “post-truth”. In the era of post-truth, every person can find facts and hypotheses that fully meet his or her desires and confirm his or her position, and yet are extremely far from the truth. The article deals with the phenomenon of post-truth in the conditions of development of information and communication technologies and modern socio-political discourse. In particular, the concept of “post-truth” and its characteristic features are considered, the role of post-truth in the modern information space is studied, the ways of neutralizing the influence of post-truth on the opinions and judgments of the audience are presented.
COVERAGE OF VOLUNTEERING IN MODERN MEDIA SPACE
Authors:   Russian State University for the Humanities, Donskaya Aleksandra A.
Published: June 2024

The topic of volunteering is one of the most relevant social topics in the modern media space. Popularization of volunteering is defined as distribution and creation of some publications about volunteering activities, which are available to a wide audience in a positive form through various media channels. There are a huge number of projects about volunteerism. Volunteer activities are also organized by schools, universities, to show that volunteerism still exists, as well as to increase the role of volunteering in the development of society, the participation of volunteers in solving urgent social problems. But the dissemination of information about a particular volunteer organization is slow or does not happen at all. This article will consider how at the moment the topic of volunteering is covered and how it is relevant in today’s society.
FEATURES OF THE REVIEW GENRE IN MODERN GAME JOURNALISM
Authors:   Russian State University for the Humanities, Leonov Vladislav I.
Published: June 2024

The article deals with the current state of game journalism, i.e. journalism related to video games. The author of the article discusses how game journalism uses various channels and platforms to communicate with the audience and provide its own content. The main part of the article analyzes the peculiarities of the review genre in video game journalism. Analyzing the scientific literature, the author of the article comes to the conclusion that the genre of review in game journalism does not correspond to the genre with the same name in traditional media. It is argued that despite the rigid framework of the game industry, which assigns journalists primarily advertising functions, some of the reviewers seek to act primarily in the interests of game users, gamers. The review genre is analyzed on the materials of the rubrics of the game Internet portal “StopGame.ru”.
THE CONCEPT AND DEVELOPMENT TRENDS OF A MULTIMEDIA PROJECT
Authors:   Russian State University for the Humanities, Prokhorova Elena N.
Published: June 2024

The article is devoted to the study of the phenomenon of multimedia projects in the modern media space. The problem of the study is the lack of a unified concept of a multimedia project and its criteria, which, in turn, makes it difficult for journalists to work with this direction in modern media. The empirical material of the study was the work of media researchers I.V. Nikishin, M.M. Luka, N.V. Kachkaeva, N.V. Kononov and special projects published in various media: Bird in Flight, Kommersant, Lifehacker, Secret Firms and No, it’s normal. A multimedia project allows you to assimilate several formats on one platform, which can either increase the involvement of a modern audience and increase the depth of study of a topic, or interfere with the process of consuming the material. The relevance of this study is due to the fact that the number of technical capabilities for the implementation of multimedia projects is increasing every year. And because of the speed of change in this format of Internet journalism, there is a need for constant analysis of approaches to producing such content. Initially, media projects were considered projects with a specific goal, a specific strategy, limited time and resources, and the presence of the head of a separate implementation team. But with the development of Internet communication, the mandatory presence of interactive elements was added to the existing criteria, and there were also trends towards commercialization and the presence of gamification elements.
Relationship between petrographic pore types and core measurements in sandstones of the Monserrate formation, upper Magdalena valley, Colombia
Authors: Cobaleda G. , Ehrlich R. , Ferm J. Barclay
Published: June 2024

Patterns of porosity in sandstones of the Monserrate Formation (Upper Magdalena Valley) exposed in polished blocks have been digitally recorded using an image processor coupled to a scanning electron microscope operated in backscatter electron mode. Additionally, porosity, permeability and response to mercury injection-capillary pressure tests were measured on some of the imaged samples. Porosity patterns were evaluated via an erosion/dilation-differencing image-processing algorithm and then classified by the selftraining classifier, SAWVEC. Changes in the resulting pore type proportions were strongly associated with changes in the mercury porosimetry curves. From the image processing data, five pore types, sufficient to include all of the variability in size and shape of the patterns of porosity, were identified. Variations in the number of pores of each type per unit cross sectional area were related to variations in permeability. The resultant relationships with mercury porosimetry demonstrated that pores of the same type tend to form microcircuits characterized by a limited throat size range. Permeability modeling showed that intergranular Pore Types 2 and 4 (secondary porosity resulting from carbonate dissolution) are responsible for permeability in the 0,01 -0,1 0 Darcy range. Type 5 pores (large molds) slightly contribute to permeability, except in coarse grained rocks where they are efficiently connected by microfractures.
Characterization and prediction of reservoir architecture and petrophysical properties in fluvial channel sandstones, middle Magdalena basin, Colombia
Authors: Ramón J. C. , Cross T.
Published: June 2024

About 1 .600 m of core from two major oil fields, and 600 m of outcrop sections near to one of the fields, integrated with thousands of core, side-wall core and outcrop porosity and permeability measurements show that petrophysical properties and reservoir continuity change consistently with the Accommodation to Sediment Supply (A/S) ratio. Channel sandstones exhibit regular, recurring motifs that are associated with changes in A/S conditions. Manifesting the lowest accommodation conditions are amalgamated channel sandstones, up to 5-m-thick, with intraclast-rich bases capped by up to 1 -m-thick floodplain mudstones. AT higher A/S conditions, slightly amalgamated channel sandstones have lateral accretion surfaces and are capped by a thicker unit of floodplain mudstones. Channel sandstones in the highest A/S conditions are single-storied, possess conspicuous lateral accretion surfaces with thick mud drapes, and have a thick cover of overbank and floodplain deposits. Detailed well log correlations, oil production and pressure data support that the former are more lateral continuous while the I after form laterally discontinuous bodies embedded in floodplain mudstones. Petrophysical properties are closely associated with subtle variations in fades, particularly degree of preservation of original bedforms, and both are stratigraphically sensitive. Petrophysical properties of identical sedimentological fades change regularly as a function of itsstratigraphic position because of variations in the rates of accumulation and degree of preservation of the sediments. In the case of fluvial strata deposited during an increase in A/S, porosity and permeability are highest in trough cross-stratified sandstones immediately above channel scour bases, and decrease upward to the next scour base. Successive channel sandstones within the same stratigraphic sequence and channel sandstones from one sequence to the next have progressively lower porosity and permeability values in an overall increase in the A/S. An inverse trend is observed during a decrease in A/S.

Published: June 2024

El propósito del estudio fue comparar las conductas de sexting, grooming, acoso y hostigamiento sexual en estudiantes de bachillerato del estado de Veracruz a partir de variables sociodemográficas. La muestra incluyó 204 estudiantes (14-19 años) quienes contestaron una ficha sociodemográfica, la prueba AMAI 2022, el cuestionario de acoso sexual para estudiantes de medicina (CASEM, Silva, 2013), el cuestionario de sexting (Gámez-Guadix, et al., 2015) y el cuestionario de solicitación e interacción con adultos (Gámez-Guadix, et al., 2017). El 77.9% señaló algún tipo de acoso y hostigamiento sexual, el 39.2 % de sexting y el 52.5% de grooming. El acoso y hostigamiento sexual fue mayor en mujeres, el sexting fue mayor en hombres y el grooming es similar en ambos sexos. No existieron diferencias con base en el nivel socioeconómico, mientras que una orientación sexual distinta a la heterosexual o usar las redes sociales por más de 6 horas incrementa la presencia de las variables.

Este artículo revisa el impacto sobre la manera de ver su proyecto de vida profesional en un grupo de estudiantes de la salud durante el confinamiento para la COVID-19 y ante la nueva normalidad post COVID-19. Se analizaron los datos de 1,879 jóvenes, edad 18 a 24 años. Para la recogida de la información se construyó un cuestionario mediante la herramienta de Google forms y fue distribuido a través de correo electrónico y de la plataforma WhatsApp. El análisis de regresión logística multivariado reveló que, vivir en el seno de un ambiente familiar no adecuado, considerar que la COVID-19 es un riesgo para ejercer su futura profesión o que ha sido un error estudiar una carrera en esta área, parecen estar asociados con la nueva manera en que los estudiantes de la salud perciben su proyecto de vida profesional durante la pandemia de la COVID-19. Es importante implementar medidas que mejoren las condiciones de salud física y mental de los futuros profesionales de la salud frente a la nueva normalidad post COVID-19.
À qui s’adressait vraiment la polémique antijudaïque à Byzance ?
Authors: Déroche Vincent
Published: June 2024

The identification of the ‘real’ audience for any given anti-Jewish treatise often remains elusive due to a perplexing blend of lengthy, ahistorical theological sections and much briefer allusions to the time of the writing. It seems more expedient to determine for each text what it is not rather than to speculate about what it ‘might be’, and to admit that long segments of some texts are actually ‘dead pages’, included for the sake of genre conventions or out of adherence to authoritative precedents, but of little significance even to the author. In some cases, these passages are a camouflage for the insertion of seemingly more relevant topics at the margins of the text. From the eleventh century onwards, anti-Jewish sections of general theological encyclopaedias and even of dedicated works have more of a protocol function: authors cannot dispense with the time-honoured practice of anti-Jewish polemics, albeit with little genuine urgency. From the fourteenth century onwards, however, a new wave of anti-Jewish writings appears more as a by-product of the increasingly intense polemics against Islam: the two genres mirrored each other, and anti-Jewish discourse was strategically instrumentalized for anti-Muslim arguments.

Lymphocystis disease (LCD) is the most frequently reported viral infection in sea bream farms in the South Atlantic and Mediterranean regions. Therefore, in this study, the presence of lymphocystis disease virus (LCVD) which is the causative agent of LCD was investigated in sea bream (Sparus aurata) farm in the Aegean region. The 78 fish samples, 40 of them showing fin/skin lesions characteristic to LCD and 38 fishes without skin lesions were collected. Samples from skin lesions and spleen and livers were taken from the fishes without skin lesions. The samples pooled were analyzed for the presence of LCDV by SYBR-Green real time PCR. All samples were found to be positive by real time PCR, but an amplification was seen only in 1 sample by conventional PCR. Sequence analysis has indicated that nucleotide sequences were belong to capsid gene of LCDV. In conclusion, this study shows that LCDV is present in Türkiye and causes serious health problems in sea bream in Izmir, Türkiye. Screening of fishes for LCDV by real time PCR is very crucial especially in fishes without skin lesions. Sequence analysis helps to determine circulating strains and variants of the virus in Türkiye.
Philosophy in Contemporary Education: Foundation or Instrument?
Authors: Kozolupenko Daria P.
Published: June 2024

The widespread adoption of new technologies has led to changes in worldview that impact the effectiveness of education and require new forms of teaching. This article demonstrates that the loss of academic motivation, growing pragmatism, and emerging new ethics characteristic of the current generation of students, loosely referred to as millennials, contradict the fundamental principles of research activities. The author notes that research-based education with the creation of a generative environment and problem-based learning is the most reasonable strategy in the natural sciences, engineering, and applied research. However, creating an analogue of this type of education in the humanities appears problematic due to the specifics of the studied objects. Although philosophy cannot be reduced to research, research-based education in its goals and declared educational ideals largely converges with philosophy. However, this convergence risks an unjustified pragmatization of philosophical knowledge, understanding philosophy only as a method and tool for better mastering other disciplines. This is most clearly demonstrated by a teaching strategy based on the use of philosophical games. The article analyzes the strategy of two types of philosophical games and other features of these games that develop critical thinking; it compares the educational goals declared by the developers (including the rationale for their relevance and compliance with the chosen teaching methodology) and the results obtained, according to the participants’ feedback. It also argues that, although philosophical games develop imagination and the ability to precisely formulate and defend theoretical positions, they do not presuppose a research position either from the point of view of the object (which turns out to be random and changes during the game) or from the point of view of the subject. The author introduces the concept of “natural generative environment,” emphasizes the importance of the axiological aspect of philosophy, and suggests paying attention to a number of existing strategies for teaching philosophy that are oriented toward this environment and partially solve the problems associated with the formation of a new type of worldview.
Experimental studies of the safety of pantohematogen as a functional ingredient in specialized products: allergenic and immunotoxic properties

Published: June 2024

The purpose of the research is to study the allergenic and immunotoxic properties of pantohematogen obtained from the blood of female Gorno-Altai maral deer as a functional ingredient of specialized products. Allergenic and immunotoxic properties were assessed in 2020–2022 by intragastric administration of pantohematogen to 395 CBA mice weighing 15–18 g, who received the drug at a therapeutic dose of 50 mg/kg and a maximum single dose of 500 mg/kg. The sensitization of the animal body after a course of administration of pantohematogen was determined by deregulation of mast cells. It has been established that when using the maximum single dose, the degranulation reaction does not exceed 0.2. It is necessary to emphasize that no changes in the leukocyte lysis coefficient were recorded in mice receiving different doses of pantohematogen. The effect of pantohematogen on the mass and cellularity of the immunocompetent organs of animals is also shown. It was noted that even the use of a dose (500 mg/kg) 10 times higher than the therapeutic dose does not affect the cellularity of immunocompetent organs. In general, the materials of experimental studies indicate the absence of allergenic and immunotoxic properties of the tested pantohematogen as a functional ingredient in the development of specialized products with specified therapeutic and prophylactic properties.
Forecast distribution of cattle manure processing technologies in the Russian Federation
Authors: Briukhanov A. Yu. , Shalavina E. V. , Vasilev E. V.
Published: June 2024

To calculate methane and nitrous oxide emissions in livestock farming requires the characteristics of produced manure and its treatment systems per a single farm and the whole region. The study aim is to specify the percentage of cattle manure processing technologies in different natural and climatic conditions of the Russian Federation and to revise the emission factor of greenhouse gases. The survey of cattle complexes established the type and amount of manure produced with a breakdown by moisture content and storage volumes. The study calculated the mass of manure processed according to the applied processing technologies. The study acquired the data on the types of manure collection and storage systems and revealed their ratio by federal districts, in more detail – in the federal subjects with bigger stock of dairy cattle. The obtained ratios allowed adjusting the coefficient required to calculate methane and nitrous oxide emissions. The coefficient reflected the share of emitted nitrogen treated or processed by a certain technology. The study calculated the emissions for cows and cattle (without cows) with the use of the adjusted coefficient and the methods of the Intergovernmental Panel on Climate Change for the Northwestern Federal District, which featured the greatest difference between the indicators from the National Inventory and the data obtained in the study. Direct nitrous oxide and methane emission in this District in terms of CO2-eq. according to the Inventory data (2021) was 180.7 thousand t/year; when calculated by the basic distribution of technologies (2021) – 388.7 thousand t/ year; when calculated by the forecast distribution of technologies (2025) – 375.8 thousand t/year. The study results demonstrated that the current tendency to upgrading the manure processing technologies towards the most environmentally friendly and compliant with the principles of best available techniques resulted in reduction in greenhouse gas emissions.

This article honors the legacy of Professor Kadir Beycioglu as founding Editor of the REAL, Research in Educational Administration & Leadership and his scholarship. A content analysis of the REAL journal titles from inception in 2016 to 2023 was performed and confirmed the mission and intentions stated for the journal. Titles were organized into themes: International, cultural, policy, and leadership. The REAL is cost-free with unrestricted access which safeguards world-wide access in the current climate of censorship, suppression, and book banning. Dr. Beycioglu’s research is tendered through the lens of his membership in ELWB, Educational Leadership Without Borders, for whom he was the Keynote speaker for the 2019 ELWB biennial conference. His research voiced on Turkish schooling and leadership parallels with prophetic insight the warning cry for researchers to counter censorship and suppression efforts globally.
In Conversation with Kadir Beycioğlu: Engaging Critically with his Scholarship on Social Justice
Authors: Cin Firdevs Melis , Karlıdag-dennıs Ecem
Published: June 2024

This paper pays homage to the late Kadir Beycioğlu's contributions to social justice and gender in education. In his later work, Beycioğlu crafted a reflexive narrative that employed philosophical methodologies to explore the concept of social justice within educational settings. Although not a predominant theme, some of his writings touched upon the institutionalisation of gender inequalities and explored how such disparities are deliberately perpetuated to uphold the status quo and sustain hegemonic power structures. In this brief article, we aim to engage in a dialectical and theoretical discourse with Beycioğlu's scholarship on social justice and gender. We intend to expand upon his arguments, critically assess some aspects of his work, and provide responses to several of his assertions. In doing so, we adopt the approach of conversationalism (Chimakonam, 2017), creating an intellectual space for critical, reflective, and productive dialogues among ourselves and in relation to Beycioğlu's later work. We hope to enrich the ongoing discourse on social justice and gender by honoring the lasting contributions of Kadir Beycioğlu to social justice and delineating his work into three distinct theoretical strands and engaging critically with his scholarship.

The previous research emphasized the importance of service quality, brand image, and customer loyalty in the context of the hospitality industry, However, there seems to be a need for more in-depth investigation into the specific mechanisms and strategies of service quality within the nature tourist camps that contribute to building a positive brand image and fostering customer loyalty. To cover this gap in knowledge, this study examined customer loyalty and brand image perception about nature tourist camps service quality in Jordan. This research is crucial due to the rapid growth of the outdoor accommodation industry and the importance of service quality. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to analyze the data collected from tourists who stayed at Wadi Rum. The results demonstrate that brand image significantly mediates the relationship between SERVRQUAL model dimensions and customer loyalty. Theoretical and practical implications were discussed.

Introduction – The operation of an adaptive coherent detection system is considered. The structure of a processing device is presented, containing a series-connected shaper of quadrature signal components that convert high-frequency input radio signals to video frequency, an adaptive multi-channel coherent storage device with threshold devices. Goal – To study the influence of amplitude and phase mismatches of quadrature channel parameters, which are inevitable in practice, on the operation of an adaptive coherent detection system. Formulation of the problem – Determine the spectral-correlation characteristics of the processed signals when the parameters of the quadrature channels are mismatched. Assess the influence of amplitude and phase deviations of the parameters of quadrature channels on the characteristics of a coherent detection system. Method – The complex variable method is used, in which the input high-frequency signals are represented at the video frequency by a pair of complex conjugate real components, shifted in phase by ninety degrees. Results – A model of the processed signal is presented at the video frequency, taking into account possible mismatches in the parameters of quadrature channels in practice. Expressions are obtained and graphs of the spectral density of the complex signal are plotted separately for the amplitude and phase mismatch of the quadrature channels. It is shown that the mismatch of quadrature channels leads to the appearance in the spectrum of the output signal of phase detectors of a component at a frequency that is the mirror frequency of the signal, which leads to an increase in the probability of false detection. The results of calculations of the probability of false detection of a signal depending on the deviation of the transmission coefficients of the quadrature channels and the phase mismatch of the reference voltages of the quadrature channels are presented. Conclusion – The significant influence of amplitude and phase mismatches of the parameters of quadrature channels on the spectral-correlation characteristics of the complex signal is shown. The mismatch of the parameters of the quadrature channels leads to deterioration in the detection characteristics of the coherent processing system. The research methodology used allows us to develop requirements for the quality of tuning quadrature channels.
ESKİ YUGOSLAVYA ÜLKELERİNDE NOSTALJİ, KİMLİK VE SİYASET: YUGONOSTALJİ’NİN SİYASİ ETKİ POTANSİYELİ ÜZERİNE BİR DEĞERLENDİRME
Authors: Güven İbrahim Fevzi , Krupalija Mustafa
Published: June 2024

En yalın haliyle Sosyalist Yugoslavya dönemine yönelik nostalji şeklinde ifade edilebilecek Yugonostalji, eski Yugoslavya ülkelerinde benimsenen sosyokültürel bir akım olarak farklı biçimlerde tezahür etmektedir. Yugonostalji’nin siyasetle ilgili boyutu ise Yugoslavya’nın dağılması döneminde patlak veren ve çok kültürlü bir arada yaşama pratiğini hiçe sayan savaşlara ve etnik milliyetçiliğe yönelik eleştirel bir tavrı yansıtmaktadır. Bunun yanında, eski Yugoslavya ülkelerinin günümüzde yoksulluk, yolsuzluk, işsizlik gibi siyasi ve ekonomik sorunlar sarmalına saplanıp kalması, Yugonostalji’nin bu sorunlardan bıkıp usanmış kitlelerce benimsenebilecek bir siyasi harekete yön verme ihtimalini akıllara getirmektedir. Çalışmada Yugonostalji’nin Yugoslavya’ya özlemi ve mevcut sorunlara karşı eleştirel bir tavrı ifade eden sosyokültürel bir akım olmanın ötesinde, Yugoslavya sonrası ülkelerde alternatif bir siyasi akıma dönüşebilme ve yeni bir siyasi kimlik oluşturabilme potansiyeli ele alınmıştır. Çalışmanın temel varsayımı, Yugonostalji’nin henüz kolektif hafızaya dayalı kültürel bir akım olmanın ötesine geçebilecek, kitleleri siyasi motivasyonla bir araya getirebilecek bir güce sahip olmadığı yönündedir.

Türkiye, is the country of origin of the olive tree and is among the world’s leading olive producers. Most of the olive production in Türkiye is concentrated in Izmir, Aydın, Çanakkale, Balıkesir, Muğla and Bursa Provinces. Bactrocera oleae (Diptera: Tephritidae), being one of the main pests of olive trees, is an important problem in olive cultivation in Türkiye. The efficacy of four Turkish populations of entomopathogenic nematodes against B. oleae pupae was determined under laboratory conditions. They were Steinernema feltiae/12, S. carpocapsae/1133, Heterorhabditis bacteriophora/70, H. bacteriophora/91, which were collected in different regions of Türkiye during our earlier studies. They were tested against the pest by using a single dose at 5 different temperatures (10, 15, 20, 25 and 30 °C). The highest infection rate was observed forH. bacteriophora/91 isolate at 25 °C, and the lowest infection rate was observed for S. feltiae/12 isolate at 10 °C.

Published: June 2024

Morphine, a potent opioid analgesic, plays a critical role in pain management but elicits complex effects on the central nervous system (CNS), demonstrating both beneficial and detrimental outcomes. This paper reviews preclinical studies to examine morphine's interactions with the CNS, notably via binding to opioid receptors, leading to analgesia as well as a series of adverse effects, including addiction, tolerance, and neurological impairments. Acute exposure to morphine alters neurotransmitter activity, gene expression, and neuronal firing rates. In contrast, chronic use results in significant neuronal damage, altered memory functions, increased pain sensitivity, and neuroinflammation, highlighting the drug's impact on neurogenesis and neural cell viability. Additionally, morphine's protective properties against neurotoxic insults are discussed, alongside its potential to disrupt cellular and molecular pathways, culminating in neurotoxicity and cognitive deficits. Given the dual nature of morphine's impact on the CNS - protective vs. harmful, depending on specific conditions such as dosage, disease type, and administration frequency - this paper underscores the necessity for further research to untangle this complex interplay to leverage morphine's pain management benefits while minimizing its risks. A thorough evaluation of morphine administration practices can help reconcile these conflicting results.
Technological revolutions and their reflexion in law
Authors: Khabrieva Taliya
Published: June 2024

The article puts forward and substantiates the hypothesis on conditionality of qualitative changes in law and the legal order by global transformations in the technological way of society: namely, the emergence of an agrarian society, its transition to an industrial society, the current transformation into a post-industrial one. Following the principle of historicism allowed us to conclude that the development of law, its sources, implementation, legal consciousness, and the legal science itself is carried out taking into account socioeconomic conditionality, which forms an independent historical element of the subject of both jurisprudence and the philosophy of law. The analysis of the revealed reflexions of technological revolutions in law made it possible to highlight a special state of socioeconomic development - it’s singularity; the presence of a society in singularity determines not only the nature of a fundamentally new group of related technologies that will dominate in the future, but also the corresponding model of social regulation, which can be represented, including law.

Food is a major driver of the biodiversity crisis. Therefore, fostering biodiversity-friendly diets is essential for reducing biodiversity loss and restoring nature. However, how accurately the public perceives biodiversity impact of food is unknown. We conducted a preregistered quota-based study with 1,744 citizens from Switzerland to examine public perceptions of food-related biodiversity footprints. Only a minority recognizes how substantially food affects biodiversity. The food-related actions perceived as being the most impactful concern more local, organic, and less animal-based foods. Participants—especially those with high problem awareness—systematically overestimated Switzerland-specific biodiversity footprints. The magnitude of this pattern varies across foods, and only a few high-impact foods (e.g., cocoa, olive oil) are underestimated. We demonstrate that a simple educational intervention can alter perceptions of biodiversity footprints. Although we find no change in the general accuracy of footprint ratings, we observe an improvement in the ability to recognize high-impact foods.
Exploring “lucid sleep” and altered states of consciousness during sleep using a mindfulness-based and visual stimulation protocol: a proof-of-concept study

The scientific study of lucid sleep (to retain critical self-awareness during ongoing sleep) has traditionally been focused on lucid dreaming and induction techniques primarily targeting REM sleep. Recently, there has been increasing interest in other forms of lucid sleep, such as certain episodes of sleep paralysis, out-of-body experiences reported during sleep, and episodes of “witnessing-sleep” as described by Indian philosophical traditions. However, empirical data on such states are sparse, partly due to the lack of specific induction techniques tailored for this purpose. In this study, we present preliminary findings from four individuals who reported different episodes of lucid sleep in a controlled laboratory environment. To facilitate these states, we developed a novel approach combining pre-sleep meditation and visual stimulation. The reported episodes include one case of lucid dreamless sleep, one out-of-body-like experience, and three different types of lucid dreams (hypnagogic, wake-initiated and dream-initiated). We monitored sleep using wearable EEG devices (Hypnodyne Zmax) and submental EMGs. Additionally, we examined the phenomenology of these episodes, which were either eye-signal verified or time-marked during periods scored as REM or non-REM sleep. Together, the lucid sleep episodes and induction protocol described here will assist forthcoming researchers in studying lucid sleep states and altered states of consciousness during sleep.
Orientation fields predict perception of 3D shape from shading

How the brain recovers the 3D structure of surfaces and objects from 2D retinal images remains mysterious. Shading patterns provide one of the most powerful—yet least understood—visual depth cues. Most theories assume the brain infers surface normals from luminance values. However, this seems unlikely as visual neurons are broadly insensitive to luminance. To identify alternative cues, we measured responses of model orientation-selective cell populations to images of shaded objects. We found a surprising statistical relationship between image orientations and surface curvatures, suggesting a novel way to estimate shape from shading. We find that the orientation-based cues not only predict striking novel illusions of shape perception when lighting varies, but also the impressive robustness of shape perception when large image modifications are introduced to directly pit luminance and image orientation cues against one another. The findings resolve the longstanding question of which image measurements drive shape from shading perception.

We present a novel method for analyzing response trajectory tracking data. Limiting behavioral experiments to discrete, key-press response measures, such as reaction times and accuracy, is unsatisfactory for observing the ongoing dynamics of cognition. We assessed the utility of continuous response tracking in Virtual Reality (VR) by comparing it to key-press responses in a classical N-back matching task. For elucidatory purposes, in both classical and VR versions of the task we first worked through analyses of discrete measures, before drawing information from the continuous trajectory tracking data in VR. Classical ANOVAs reproduced effects of visual working memory load in an N-back task. Violations of ANOVA assumptions suggested effects were buried in the noise; some of these were revealed in subsequent survival analyses, namely frequency neglect (a strong preference for match responses despite the infrequency of this response category) in the fast responses and category frequency-tuned response in the slow responses. Spatiotemporal survival analysis (StSA), our newly proposed method of analyzing response trajectories, revealed that all these effects also occur in the VR conditions. In addition, initial divergences towards the wrong responses were corrected later in the course of trajectories in the non-Match trials. While the StSA method is theory-free and can be used for exploratory purposes, we present examples of hypothesis testing in StSA.
Aesthetic appeal of prosodic patterns correlates with their effectiveness for speech segmentation

Could the aesthetic appeal of linguistic features influence their learnability, and in turn their long-term stability during language change? Focusing on prosodic patterns, we investigated the baseline assumption that linguistic features like stress patterns affect aesthetic appeal. Listeners’ ratings of isochronous words and words with initially, medially or finally lengthened or shortened syllables revealed that, indeed, different prosodic patterns differed in their aesthetic appeal in terms of ‘liking’, ‘beauty’ and ‘naturalness’. Furthermore, aesthetic ratings of these prosodic patterns corresponded to their effectiveness for speech segmentation in previous experiments, suggesting a potential connection between aesthetics and language processing. This research opens up new avenues for future research on the role of aesthetic preferences in language acquisition and language change.
Ensemble Perception of Faces with Naturalistic Occlusions

The visual system takes advantage of redundancy in the world by extracting summary statistics, a phenomenon known as ensemble perception. Ensemble representations are formed for low-level features like orientation and size and high-level features such as facial identity and expression. While recent research has shown that the visual system forms intact ensemble representations even when faces are partially occluded via solid bars, how ensemble perception is impacted with the addition of naturalistic objects such as face masks or sunglasses is largely unknown. To investigate this, we conducted a series of experiments using continuous report tasks in which faces (either varying in identity or expression) were partially occluded with a surgical mask or sunglasses and participants had to report the average face using a face wheel. We found evidence that participants could still accurately extract the average even when a significant portion of it was occluded with either face masks or sunglasses. In a second experiment, however, we found performance was worse when the face wheel was variable trial to trial. Thus, part of the preservation of performance in occlusion arises from the visual system learning the features of the particular face wheel being used. Overall, our results suggest that the visual system is able to establish robust ensemble representations for faces with naturalistic occlusions, but that robustness appears to be supported at least partially by learning information about the particular features that are informative for a given set of faces.
