Published: June 2022

The power grid is an important connection between power sources and users, responsible for supplying and distributing electric energy to users. Modern power grids are widely distributed and large in scale, and their security faces new problems and challenges. Information entropy theory is an objective weighting method that compares the information order of each evaluation index to judge the weight value. With the wide application of entropy theory in various disciplines, the subject of introducing entropy into the power system has been gradually concerned. This article aims to study the smart terminal security technology of the power grid perception layer based on information entropy data mining. This article analyzes its related methods and designs a smart terminal for the power grid. On this basis, a data analysis platform is built and a safety plan is designed. The result is that the average absolute error, root mean square error, average absolute percentage error, and mean square error of the platform's power load forecast are 1.58, 1.96, 8.2%, and 3.93, respectively. These error values are within the ideal range, and the data processing ability is strong. The packet loss rate of the adversary's eavesdropping was tested, and the average packet loss rates at locations a, b, c, and d were 1.05, 1.2, 1.81, and 2.2%, respectively. Data packets will be definitely lost, so the platform is highly secure.
Chirality-modulated photonic spin Hall effect in PT-symmetry
Authors: Liang Chengkang , Liu Dongxue , Liu Rao , Deng Dongmei , Wang Guanghui
Published: June 2022

The photonic spin Hall effect (PSHE), featured by a spin-dependent shift driven by its polarization handedness, is proposed to facilitate the applications in precision metrology and quantum information processing. Here, due to the magnetoelectric coupling of the chirality, the PSHE is accompanied with Goos–Hänchen and Imbert–Fedorov effects. Taking advantage of this superiority, the transverse shift (TS) and longitudinal shift (LS) can be applied simultaneously. Rearranging the PT-symmetric scattering matrix, the responsive PSHE near the exceptional points and their basic physical mechanisms are discussed in detail in the case of complex chirality κ. Re[κ] and Im[κ] regulated the rich (at multi-angle), gaint (reach upper limit) and tunable (magnitude and direction) TS and LS, respectively. Based on the chirality-modulated PSHE, the novel applications in binary code conversion and barcode encryption are proposed systematically. By incorporating the quantum weak measurement technology, our applications provide new mechanisms to realize optoelectronic communication.
The Effect of Children’s Exposure to the YouTube Platform Moshaya Family Channel on Socialization of the Saudi Child Regarding Life Satisfaction
Authors: Qutub Afnan A. , Muhammad Alaa A.
Published: June 2022

This study aims to measure the effects of exposure to a YouTube platform, the Moshaya Family Channel, on the socialization of children. We monitored the content provided by the channel and how children are affected by it in terms of moral and behavioral aspects, specifically the impacts of their repeated exposure to the programs on their life satisfaction. This needed to be studied due to the increase in views and subscriptions to the channel, and children’s level of attachment to the presented content. This research uses the survey method. An online questionnaire was used to obtain information from a study sample of 338 Saudi mothers whose children are watching “The Moshaya Family Channel.” Children’s ages ranged from 5 to 13 years old. The most important result is that a big proportion of children have the awareness of terms like subscribe, share, like and views. The reason for that is due to their being influenced by the idea of popularity and their desire to make their own YouTube channel. The research also found that a big proportion of children preferred prank content in the channel and described it as interesting, which pushed them to imitate these pranks in their lives. The research found that most mothers don’t like their children to watch the channel because it incites the child to prank others and prompts buying behavior in children. This confirms the role played by new media platforms, especially YouTube, which result in children acquiring values not only for entertainment, but also a tool for learning, communication and entertainment.
A semiotic analysis of images of Saudi Women’s rights in caricatures in light of Saudi Women’s empowerment
Authors: Al-Ghamdi Naimah Ahmed , Alqahtani Abeer , Alshahrani Lama , Elyas Tariq
Published: June 2022

Many caricaturists get the idea for their caricature from current issues of society. The philosophy of the caricature lies in the opinion it presents, which discusses society’s goals, culture, and crises, and it is represented in an ironic way to deliver its visual message. The fight for women’s rights, inequality, and discrimination are examples of issues concerning Saudi women that have been represented by several caricaturists. Hence, the aim of this paper is to investigate female and male caricaturists’ linguistic and semiotic representation of Saudi women’s challenging issues. Following (Kress and Van Leeuwen. 2006.Reading images: The grammar of visual design, 2nd edn. London: Routledge), a social semiotic multimodal approach to the analysis is adopted in this study, which is drawn from Halliday’s social semiotic theory. Twenty caricatures were carefully selected based on the content and the issues that are being discussed in the caricatures with a consideration of their relation to the aim of the study. The present study contributes to enriching Saudi women’s rights in relation to Saudi Vision 2030. The research is significant in that, in examining women/male caricaturists’ representations of the challenges and opportunities of Saudi women empowerment prior/after Saudi Vision 2030 in the workplace, social life, it contributes to understanding the supportive caricature discourse, basic social values for Saudi women, the pressures they undergo, and the success they have achieved so far in attaining their rights. The study findings show that both the semiotic and verbal elements of the caricatures were significant in delivering the messages for women’s rights in the new Saudi.
Electromechanical properties of housed piezoelectric CTGS resonators at high temperatures – Modeling of housing influence
Authors: Schulz Michal , Ghanavati Rezvan , Kohler Fabian , Wilde Jürgen , Fritze Holger
Published: June 2022

The use of piezoelectric sensors in harsh environments requires their protection by housing. Therefore, it is essential to select materials used for the housing carefully. They should not only withstand the same conditions as the active element while providing protection for it, but also influence the piezoelectric component as little as possible. Mechanical stress or electric short-cut of the signals must be avoided as it leads to strong damping and to reduction of e. g. mass or temperature resolution. Therefore, understanding of housing impact on the piezoelectric sensor plays an important role in research and development.

Housed as well as unhoused CTGS resonators are analyzed at temperatures up to 1000 °C. The electrical impedance in the vicinity of the resonance frequency is acquired and modeled by electric equivalent circuits that are fitted to the data. The circuit models describing unhoused and housed CTGS resonators are an extension of the Butterworth-van Dyke equivalent circuit. Analysis of the data reveals that the realized housing impacts the behavior of the CTGS resonators only slightly above ca. 600 °C, whereas this influence is negligible for typical applications.

Appropriate techniques to quantify greenhouse gas emission reductions in cities over time are necessary to monitor the progress of these efforts and effectively inform continuing mitigation. We introduce a scaling factor (SF) method that combines aircraft measurements and dispersion modeling to estimate urban emissions and apply it to 9 nongrowing season research aircraft flights around New York City (NYC) in 2018–2020. This SF approach uses a weighting function to focus on an area of interest while still accounting for upwind emissions. We estimate carbon dioxide (CO2) emissions from NYC and the Greater New York Area (GNA) and compare to nested inversion analyses of the same data. The average calculated CO2 emission rates for NYC and the GNA, representative of daytime emissions for the flights, were (49 ± 16) kmol/s and (144 ± 44) kmol/s, respectively (uncertainties reported as ±1σ variability across the 9 flights). These emissions are within ∼15% of an inversion analysis and agree well with inventory estimates. By using an ensemble, we also investigate the variability introduced by several sources and find that day-to-day variability dominates the overall variability. This work investigates and demonstrates the capability of an SF method to quantify emissions specific to particular areas of interest.

Retrospective Analysis of the Process of Education at the University
Authors:   Saratov National Research State University named after N. G. Chernyshevsky, Ivanov Maxim V.
Published: June 2022

The purpose of the article is to conduct a comparative analysis of the opinions of teachers on the process of educating a student, his objectivity and specificity. In the article is shown that the situation in domestic education, which developed in the 90s of the XX century, the educational component of higher education in Russia was almost completely destroyed, and there was a significant narrowing of the target orientation of higher education to the tasks of professional and activity formation of a specialist, instead of a comprehensive development of the student’s personality. The article provides a comparative analysis of the opinions of the most prominent teachers of the current and earlier period of domestic pedagogy on the process of educating a student. Since educational interaction with students did not stop in some schools, some practices of educational interaction that are successfully used in schools are proposed for consideration for transferring to university realities. Some possibilities of educational potential in the university are noted, including the effectiveness of education through work with leadership qualities, the use of the team as an educational environment, etc. The concept of “university identity” is derived as an important criterion for the upbringing of the student, as well as the result of pedagogical interaction with the student. In conclusion, it is concluded that despite the introduction of an exemplary upbringing program in an educational organization of higher education, upbringing remains a secondary appendage of the educational process. To solve the identified problem, the need to work with the teaching staff was noted.

The paper substantiates the necessity of forming ecological and patriotic culture in the younger generation at the present stage of society development. The purpose of the article is to search for effective forms and methods of formation of ecological and patriotic culture among the representatives of the younger generation. It describes the experience of team work at Saratov regional educational institutions of different levels (schools and universities) in the implementation of the regional project “Green Memory Alley “ for the period 2005-2021. The project includes the following stages: 1. Development of environmental awareness and patriotic feelings and emotions in the interacting participants based on value preferences; 2. Guidance of the project participants to the ecological and patriotic perception of reality; 3. Participants’ awareness of the interaction between the personal and social meaning of environmental and patriotic activities; 4. Interaction of participants in the ecological-patriotic educational space. A significant basis for participants’ work on the project “Green Alley of Memory” is modeling and arrangement of the green alley in memory of the soldiers who died during the Great Patriotic War by means of the artistic, aesthetic, environmental, spiritual, moral and symbolic value of plants. Сonclusion. It has been revealed that the symbolic concepts ‘Social memory of the war’ and ‘Living organisms and plants’ proposed in the project can be system-forming elements of the value bases of ecological and patriotic culture in the younger generation. It is aimed at developing insights into preservation and maintenance of life on a planetary scale. On the basis of the research, ecological and patriotic culture is presented as a personal phenomenon that expresses the essential relationship of such categories as culture, patriotism, ecology and values reflecting involvement in the traditions of civic duty, service to the Motherland and love for nature, life, and the universe. The research singled out, described and validated the cognitive-content, motivational-value, organizational-activity components and the stages that form the structure of ecological-patriotic culture.

Published: June 2022

Wnt/β-catenin signaling plays a key role in maintaining homeostasis, which is disturbed in hypertension. Taking into account the lack of literature describing changes in the Wnt/β-catenin pathway in the adrenal glands under conditions of elevated arterial pressure, here we compare the expression of WNT4, WNT10A, β-catenin, and GSK-3β in the adrenal glands of hypertensive rats of various etiologies. The studies were carried out on the adrenal glands of rats with spontaneous hypertension (SHR), renalvascular (2K1C), and deoxycorticosterone acetate (DOCA)-salt. Immunohistochemical and PCR methods were used to identify the molecular components of the canonical signaling pathway and to evaluate gene expression. Immunoreactivity and expression of WNT4, WNT10A, β-catenin, and GSK-3β in adrenals of SHR was decreased, compared to control rats. In adrenals of 2K1C rats, intensity of immunohistochemical reaction and expression of WNT4 and β-catenin was lower, while immunoreactivity and expression of WNT10A and GSK-3β were higher, compared to normotensive animals. Significantly stronger immunoreaction and expression of WNT4, β-catenin and GSK-3β but weaker immunoreactivity and expression of WNT10A were noted in adrenals in DOCA-salt rats, compared to control rats. In conclusion, our data provide new molecular information indicating that the canonical WNT pathway is disrupted in the adrenal glands of hypertensive rats. They show that the dysregulation of the WNT pathway depends on the etiology of hypertension.

The Political Economy of the Next Pandemic
Authors: Van Bergeijk Peter A.G.
Published: June 2022

While the pandemic and recovery unfold in real time, this article investigates some of the major themes on preparations for the next pandemic. Humanity cannot rely on modern medicine to beat the next ‘disease X’ and the world cannot afford the extortionate health and economic policy interventions during the COVID-19 pandemic again. From the COVID-19 pandemic we learned that the international economic organizations suffered from disaster myopia and that the self-image of the advanced economies is distorted. It also has become apparent that ‘beggar-thy-neighbor’ health care was generally practiced while global health care should have been the norm. A discussion on the related issues of rationing, triage and scarcity of health care during a pandemic is urgently needed. All in all, a major global investment project is necessary to reduce the vulnerability to and impact of pandemics. As inequalities to a large extent determine pandemic vulnerability and adjustment of SDGs is necessary.

Authors: Duarte Aldira Guimarães , Avila Carlos F. Domínguez
Published: June 2022

O artigo explora a denominada “guerra das estátuas” e seus desdobramentos no Brasil, principalmente sob a perspectiva das correlações entre patrimônio, memória coletiva e política cultural. Trata-se de um ensaio de interpretação, de natureza interdisciplinar, e com forte influência teórico-metodológica na história conceitual. O artigo também dialoga com os estudos e pesquisas sobre a qualidade da democracia, especialmente na sua dimensão da Participação Política, inclusive no que diz respeito à Participação Política Não Convencional, quer dizer, protestos, manifestações, e/ou ação coletiva. Outrossim, são discutidas e deliberadas algumas alternativas e boas práticas na formulação e implementação de políticas públicas setoriais. O principal argumento do artigo sugere que, diante de estátuas polêmicas ou incongruentes com os valores das atuais gerações de cidadãos, as melhores alternativas seriam a ressignificação ou a remoção das mesmas.
Despliegues de intimidad en Bestiarium, de Dulce María Loynaz: Descubrimientos zoomorfos en su poética
Authors: López Cruz Humberto
Published: June 2022

El poemario Bestiarium, de la poeta cubana Dulce María Loynaz y quien lo mantuvo inédito por décadas, entrega una fauna que se apropia de lo que luego se vería como un discurso contestatario para retar al poder que subestima a la poeta. Si como estudiante fue suspendida por no aportar información adicional, por este medio, los animales elegidos van, con su presencia, a desafiar la autoridad y, a su vez, a acercarse a la intimidad de la voz lírica. No parece ser tan solamente un ejemplo de zoolatría por parte de Loynaz; la particularidad de la selección fáunica adosada al sentimiento inscrito advierte que hay un motivo ulterior que urge develar. La palabra la poeta, transmutada en verso, se afirma en su originalidad y desplaza el centro del poder a la periferia. Bestiarium se suscribe, entonces, bajo tres registros diferentes: su función social, su función didáctica y, no menos importante, su función poética.
El lenguaje del fatalismo en la proposición lírica de los pasillos ecuatorianos
Authors: Núñez Torres María Giovanna , Dillon Pérez Francisco Xavier
Published: June 2022

El pasillo ecuatoriano como expresión de sentimiento, amargura y desahogo emocional, siempre encierra por lo general un grado de fatalismo en su diseño y estructura, principalmente debido al propósito de enaltecer los valores culturales del pueblo ecuatoriano muy especialmente en lo que atañe al espíritu nacional y a las reacciones de la definida idiosincrasia propias de este país. El objetivo de esta investigación fue identificar la presencia del lenguaje fatalista expresada en la letra de algunos pasillos ecuatorianos para identificar posibles patrones en la utilización de este. La investigación fue fundamentada además en el paradigma de investigación Hermenéutico Interpretativo de metodología cualitativa con un proceso de investigación de tipo documental, donde se analizó la literatura comercial como cancioneros y discos magnéticos de acetato cuyo nivel de difusión es público. Esta información recopilada se catalogó llegando a la conclusión de que concurre la representación de fatalismo evidente en la creencia en una fuerza superior, sentimientos de frustración y desdicha, rebeldía frente a la realidad, paradójica resignación, obsesión por el dolor, tedio, hastío y melancolía y evasión a través de la ingesta de licor o algún alucinógeno, mismos que se encuentran presentes en los rasgos conductuales y la idiosincrasia del pueblo ecuatoriano.
Satisfacción y demandas laborales en un grupo de personas jóvenes de entre 18 y 38 años que realizan teletrabajo en Call Centers en Costa Rica
Authors: Gutiérrez Arroyo Paula , Herrera Solís Hillary , López Muñoz Selena , Montero Jiménez Yanela , Mora Molina María José
Published: June 2022

Actualmente nos encontramos en una situación de crisis sanitaria mundial (COVID-19) que afecta directamente múltiples áreas socioeconómicas, encontrándose entre ellas el sector laboral que se ha visto forzado a tomar medidas y acudir al teletrabajo, lo que tuvo como resultado una gran variedad de características positivas y negativas en la vida de las personas. Por ende, la presente investigación busca mostrar la relación que existe entre la satisfacción y las demandas laborales en un grupo de personas que realizan teletrabajo en call centers ubicados en Costa Rica, basado en la hipótesis de que, a mayor cantidad de horas de teletrabajo realizadas, mayores serán las demandas laborales y menor la satisfacción laboral de la persona. Para esto, se aplicaron dos escalas, una con el fin de medir las demandas laborales, y la otra para la satisfacción laboral, a una muestra de 100 personas. En cuanto a los resultados, estos arrojaron que, a mayor cantidad de horas diarias de teletrabajo, mayor percepción de demandas laborales y menor satisfacción laboral; caso contrario, quienes laboran menos horas al día perciben una menor demanda laboral y mayor satisfacción, por ende, es posible aprobar la hipótesis.
A comparative study of abstraction and informational density in higher and lower Indonesian graduate students' L2 English academic texts
Authors: Subandowo Dedy
Published: June 2022

The language features of the second language (L2) English academic texts written by Indonesian graduate students enrolled in Hungarian higher education are employed in the present study. The study focuses on the level of abstraction and informational density in student assignments in particular. Seven high-stakes essays were collected from seven Indonesian graduate students registered in the faculty of Social Sciences at three different Hungarian universities. Coh-Metrix, a corpus-based computational tool, was used in this study to examine indices of content words and abstraction. As for the comparison between higher and lower proficiency level students, parametric statistics were used to conduct a quantitative analysis of the selected linguistic features, including nouns, verbs, adjectives, adverbs, pronouns, and concreteness and abstraction. The results show that C1 English proficiency level students outnumber B2 students in terms of informational density. Their texts are more abstract than those of B2 students.
The Fourth of the Fourth: On the Genesis and the Early Performances of the Allegretto, pizzicato Movement of Béla Bartók's String Quartet No. 4
Authors: Németh Zsombor
Published: June 2022

As already pointed out by László Somfai in the late 1980s, Béla Bartók's first fully developed five-movement realization of the so-called “bridge” or “palindrome” form was only an afterthought, a further development of a composition originally intended as a cycle of four movements only. As also discussed briefly by Somfai, the evolution of the Allegretto, pizzicato movement itself had distinct stages. A recently surfaced source further clarifies these compositional phases, among others confirms the existence of a 140-measure-long version without a proper conclusion, which, at one point, the composer considered as a definitive version (for which only the ending needed to be composed) and tested with the Waldbauer-Kerpely Quartet. The present article re-examines the compositional process of Bartók's String Quartet no. 4 with an emphasis on its additional fourth movement and discusses the different compositional phases of the Allegretto, pizzicato.
The association of TEX15 haplotype with male infertility in Vietnamese individuals
Authors: Duc Duy La , Phuong Anh Nguyen , Thuy Duong Nguyen
Published: June 2022

Infertility is a global concern that affects 15% of couples, and roughly half of those cases are male-specific. Among the genetic factors that contributed heavily to male infertility, TEX15 (testis-expressed gene 15) has been studied across multiple cohorts worldwide and identified to relate to meiotic recombination failure and DNA repair system malfunction. To assess the relationship between male infertility and TEX15 in a Vietnamese cohort, we performed a case-control association study of polymorphism TEX15 rs323345 and a further analysis of haplotypes of TEX15 rs323345 and TEX15 rs142485241. A total of 420 unrelated Vietnamese males, including 212 infertile patients and 208 healthy controls, were recruited for the present study. The genotype and allele frequencies of the polymorphism TEX15 rs323345 were determined by PCR-RFLP method. The results showed that the distribution of genotypes of this polymorphism followed Hardy-Weinberg equilibrium (p-value > 0.05), but the association between the polymorphism TEX15 rs323345 and male infertility was not significantly different in all three models (additive, dominant, and recessive) (p-values > 0.05). However, haplotype analysis revealed that haplotype GT of the two variants (rs323345 and rs142485241) of the TEX15 gene was correlated with an increased risk of male infertility (p = 0.023, OR = 1.937, 95% CI = 1.085-3.456). This study demonstrated that haplotype analysis could unveil potential associations in genes that could normally be unnoticed in an individual SNP analysis.
FEM ANALYSIS OF BLAST PROOF SANDWICH COMPOSITE TO DETERMINE THE OPTIMAL GROUND CLEARANCE OF MINE PROTECTION VEHICLE
Authors: Khuntia Sravan Kumar , Joshi Jithin , Suresh Kumbhar Avinash , Bhowmik Shantanu
Published: June 2022

It has been a constant endeavor of the armed forces to build vehicles that can transport soldiers in hostile terrain while reducing threats to their lives. The strength of these vehicles used to mitigate the blast effect is directly proportional to the mass of the explosives used for the blast. The challenge lies in designing an operationally effective mine protection vehicle (MPV) with appropriate protective measures to safeguard the lives of its occupants while maintaining high fuel efficiency high. It has been reported that the greater the standoff distance of explosive from the hull of a vehicle, the less is the effect of the blast. However, the ground clearance of a vehicle cannot be increased beyond a limit as it would seriously affect its stability. In this study, the optimal ground clearance of MVPs was investigated so that any blast would have the least effect on the vehicle chassis. The blast-proof material used in this study is a novel sandwich composite invented by Ariharan et al. (2019).
Mechanisms controlling the hydraulic conductivity of anionic polymer-enhanced GCLs
Authors: Norris A. , Scalia IV J. , Shackelford C. D.
Published: June 2022

The hydraulic conductivity (k) of specimens of enhanced-bentonite geosynthetic clay liners (EB-GCLs) comprising anionic polymers permeated with two concentrated salt solutions, 500 mM NaCl and 167 mM CaCl2, was measured to determine the effects of polymer properties and specimen preparation method on the k and the associated roles of polymer retention and elution in dictating the measured k. The results of hydrogel formation tests illustrated that poly(acrylic acid) hydrogel was formed in solutions tested during EB-GCL hydration. A dry sprinkling method of specimen preparation resulted in low k (≤5.5 × 10−11 m/s) in multiple EB-GCLs, with a low fraction (≤2.5%) of retained polymer. In contrast, polymer elution from EB-GCLs prepared using a dry mixing method resulted in interaggregate seepage and an increase in k. Higher polymer retention occurred for the wet-mixed EB-GCLs, but did not directly correlate to low k. The long-term k of the EB-GCLs is dependent on several factors, including (i) formation of hydrogel, (ii) mobilization of hydrogel into and blocking of the most conductive pores, (iii) balance of seepage forces and hydrogel crosslink bond strength, (iv) kinetics of hydrogel formation, and (v) adsorption of polymer to the surfaces of the bentonite particles or aggregates of particles.
Suitability of electrochemical test methods for evaluating corrosion of steel in alkali-activated slag concrete
Authors: Ma Qianmin , Bai Yun , Yang Changhui , Basheer P. A. Muhammed , Nanukuttan Sreejith V.
Published: June 2022

The electrochemical tests commonly used for evaluating reinforcement corrosion in Portland cement-based concrete may not be appropriate for testing alkali-activated slag (AAS) concrete due to its different pore structure and pore solution composition. In this article, corrosion behaviour of the steel bars in 12 AAS concrete mixes with different alkali concentration and modulus of sodium silicate solution was monitored by using gravimetric mass loss measurement. The results obtained from other electrochemical tests were compared to the gravimetric mass loss to determine their suitability for assessing the corrosion of steel in AAS concrete. It was found that only 7.8–28% of the mass loss was accounted for by the macrocell current for AAS concretes, indicating that this type of test underestimates the corrosion of the steel in AAS concrete. The steel bars in the AAS concretes gave a much higher negative half-cell potential value, presumably due to the influence of sulfides. In summary, it has been established that the criteria for assessing the onset and progress of corrosion of steel in Portland cement concrete are not suitable for the same purpose in the range of AAS concretes studied.
Thermal and mechanical properties of concrete containing porcelain ceramic tile waste as fine and coarse aggregates
Authors: Gharibi Hamed , Mostofinejad Davood
Published: June 2022

Sustainable development relies on efficient energy consumption and environmental protection. The construction industry accounts for a significant portion of global energy consumption. Concrete, as the most commonly used construction material, can play an important role in reducing global energy consumption owing to its thermal properties and its capacity for using waste materials as mix ingredients. In this study, the use of porcelain ceramic tile waste (PCTW) as a replacement for natural fine and coarse aggregates in concrete, both individually and in combination, was investigated. The thermal conductivity, compressive strength, density and water absorption of concretes made with PCTW aggregate were investigated in a series of novel experiments using 77 specimens prepared from 11 concrete mix designs. Compared with conventional concrete, it was found that the use of non-recyclable porcelain waste reduced the heat penetration rate by about 10.8°C, reduced the thermal conductivity by 38% and increased the compressive strength by 42%.

Antalya’nın sit alanlarından biri olan Kaleiçi’nde, özgün plan tipine, yapım tekniğine ve kültürel dokuya sahip çok sayıda geleneksel konut bulunmaktadır. Roma, Bizans, Selçuklu ve Osmanlı Dönemi’nden günümüze kadar farklı kullanıcılar bu konutlarda yaşamlarını sürdürmüşlerdir. Farklı medeniyetlerin bölgede hüküm sürmesi, toplumların, yaşam biçimlerinin dolayısıyla da konutların değişimine neden olmuştur. Geçmişte geleneksel konutların yoğunlukta olduğu ve kent halkının konakladığı Kaleiçi bölgesi, günümüzde çoğunlukla turizm ve ticaret amaçlı kullanılmaktadır. Antalya’nın en önemli turizm bölgesi olan Kaleiçi, tarihi ve turizm değeri nedeniyle çalışma kapsamına alınmıştır. Bölgede yer alan en önemli konutlardan biri olan 19. Yy yapısı Ömer Lütfü Efendi Konağı, sit alanında yer alan en eski ve en büyük konaklardan biridir. 1989 yılında pansiyona çevrilen ve 14 yıl boyunca aynı işlev ile kullanılan yapı, çalışma alanı olarak belirlenmiştir. Çalışmanın amacı geleneksel konutun, iç mekanda oluşan değişimlerini belirlemek ve elde edilen verilerle kültürel mirasın gelecek nesillere özgün olarak ulaşabilmesi için restorasyon çalışmalarındaki doğru uygulamaların önemini vurgulamaktır. Çalışmanın sonucunda yapıya ait ulaşılabilen tüm veriler analiz edildiğinde; inşa edilen ek yapının plan şemasına büyük oranda etki ettiği, ayrıca bakımsızlık, yanlış uygulamalar ve yapının uzun süredir kullanılmamasının sonucu olarak cephede ve iç mekânda yıpranmaların meydana geldiği, karakteristiğini öne çıkaran özgün mimari elemanlarında da eksilmeler olduğu tespit edilmiştir.

Characteristics and the use as culture media of protein hydrolysate from Locusta migratoria were determined in comparison with different peptones. After powdering, it was hydrolyzed chemically (acid hydrolysis) and obtained product Locust Peptone (LP). The contents of protein, fat, nitrogen, ash, minerals, total sugars and amino acids of LP were determined and it was seen that it has both organic and inorganic materials enough to use as a component of the medium. The effects of different concentrations added 20g/l glucose of LP on the growth of four test bacteria (Escherichia coli, Bacillus subtilis, Pseudomonas putida and Staphylococcus aureus) and test yeasts (Rhodotorula glutinis, Candida albicans, Saccharomyces cerevisiae) were investigated and it was found that the optimal concentration for bacteria and yeast are %0,6 and LP was compared with bacteriological peptone (BP), fish peptone (FP) and meat peptone (MP) .The obtained results with surface streaking and shaking culture procedures showed that LP yielded a little higher or equal FP and BP in both normal bacteria, but these values were lower than values obtained from MP. The results show that LP performed similar to or even better than commercial peptones as nitrogen sources for microorganisms growth. A new peptone has been developed from locust for microbiological media in the present study.
Are you for real: writing verbatim performance with ethnographer’s tools
Authors: Rinne Nora
Published: June 2022

Verbatim technique connects concepts such as ‘actual’, ‘real’, ‘original’ and ‘authentic’ to theatre, performance art and creativity. In this article, I consider the roles of creativity, art, veracity and reality when composing a performance text that is based on the ‘actual words’ of ‘real people’. What is the truth claim in verbatim performance, and how does it operate together with artistic creativity? My approach is that of an artistic researcher conducting research with children. When I collect materials for my verbatim performances, I use many of the same techniques and methods that childhood studies ethnographers use in their fieldwork. The performative turn in social sciences, with post qualitative inquiries and non-representational methodologies, and the educational turn in art, bring these fields even closer together. Both fields face the questions of veracity and creativity without any simple oppositional structure. I claim that, instead of concentrating on the friction between creativity and truth, it is important to acknowledge that creativity can be needed in order to lie less. I argue that ethnographic objects can lie if they are presented to us dead. Although performance art, or live art, claims to be the epitome of liveness and immediacy, it actually expresses the impossibility of guaranteed unmediated presence. The creative skills of an artist and ethnographer are needed, to keep the transcript and presented materials alive and communicating, to ensure that research remains reciprocal.

Se evaluó las zonas de aptitud actual y futura para los cultivos de cacao (Theobroma cacao L.) y café (Coffea arabica L.), en escenarios de cambio climático en la región del Soconusco, Chiapas, México y se definieron las áreas donde aumentó o disminuyó la aptitud de la tierra. Lo anterior permite tener información para recomendar su manejo y conservación. Se emplearon dos metodologías: ponderación de factores y factores limitantes; ambas con base en los valores óptimos y extremos de tolerancia de cada cultivo para cada requerimiento edafoclimático. Con la primera, se determinaron las áreas potenciales para el establecimiento de los cultivos; con la segunda, se diferenciaron las combinaciones de las variables ambientales que tuvieron lugar dentro del área de estudio. Se evaluaron escenarios de cambio climático y se determinó la distribución y superficies de aptitud. Además, se realizó una comparación entre aptitud actual y futura de ambos cultivos para cuantificar el impacto del cambio climático. Los resultados indican que la aptitud futura de la tierra tendrá una disminución de las áreas potenciales para el establecimiento de ambos cultivos de entre 4,5 y 4,8% para café y de 7,2 a 9,3% para cacao.
Philosophy of Love: Analytical Approach of Raja Halwani
Authors:   Institute of Philosophy and Law of the Siberian Branch of the Russian Academy of Sciences, Novosibirsk, Diatlov Ivan
Published: June 2022

Philosophy of love as a subfield of moral philosophy and history of philosophy questions the very foundations of how people love each other. Within the philosophical debate, not only the sources of love but forms and types are questioned. Does the source of love correspond to a concrete form of love? What is the difference between parental love and friendship love? What is the main difference between romantic love and the abovementioned? A philosopher from Chicago, Raja Halwani made a methodological and pithy impact in the debate. On the one hand, his main achievement in the recent debates is the distinction between two kinds of love: romantic love 1 and romantic love 2. Halwani notes that the main disagreement among philosophers stems from the fact that philosophers usually don’t see this difference. And if philosophers would keep this difference in mind, it would clarify our debates. On the other hand, professor Halwani doesn’t propose a conceptual novelty but interestingly refines the current debates on love’s aspects. These debates are debates concerning the main characteristics of love and how we can defend these characteristics. Halwani clarifies the central concepts of romantic love such as “constancy”, “exclusivity”, “uniqueness”, “irreplaceability”. The philosopher devoted special attention to reflections upon how exactly we can apply existing moral theories to love. At the end of the article, an attempt is made to compound many of Halwani’s statements about RL1 and RL2 in a unified table.
Theory and Methodology of Value-Sensitive Design: Critical Analysis

The paper is devoted to Value Sensitive Design (VSD). This approach, widely presented in foreign scientific and specialized literature, has not been reflected in the Russian-language discourse. The authors of the study consider the theoretical foundations and methodological tools of VSD, clarify the conceptual apparatus, and also carry out a critical analysis of some of its main provisions (in particular, the question is raised about the absence of a philosophical theory of values, the eclecticism of the modern approach, insufficiently developed methods of cooperation with engineers, designers and potential stakeholders). VSD is viewed in the context of technology assessment and socially responsible innovation. We are talking about a diverse set of practices for the rational shaping of technologies, taking into account the values of society, suggesting a more active and conscious involvement of ordinary citizens (not experts) in the discussion of issues related to the development and design of technologies. An understanding of values with an emphasis on ethics and morality raises the question of achieving a balance between competing values and choosing the desired values, taking into account the diversity of interests of direct and indirect stakeholders. In this regard, two main goals of the VSD stand out. On the one hand, it involves identifying and critically analyzing desirable or limiting values that have been (intentionally or unintentionally) inscribed into existing technologies. On the other hand, VSD offers practical recommendations on how to deliberately and purposefully inscribe socially approved values into the design of new equipment, software, databases, and algorithms. Finally, the article defines the directions of possible applied research: (a) the development of the theory and methodology of change management through structuring the change management process according to the hierarchical principle of interaction, as well as identifying persons and groups that are affected by organizational changes and how; (b) fundamental aspects of human-machine interaction, in particular, human-robot interaction (HRI), which is of great practical importance for the design and production of socially responsible service robotics.
