Authors: Andaru Arkanu , Riyadi Praditiyo , Nafian Muhammad
Published: September 2023

The need for hydrocarbon energy, especially oil and gas, requires continuous exploration of hydrocarbon reserves, especially in eastern Indonesia. Tanimbar Islands, Maluku was chosen to be the research area because of its complex subsurface geology and is located on the fold thrust belt resulting from tectonic evolution. In this research, an innovation is carried out using joint inversion modeling by correlating physical parameters from two different geophysical data, which are gravity and geomagnetic. The purpose of this research is to determine the subsurface mapping of the research area, determine the density and susceptibility values of rocks, and determine the structural patterns that exist in the subsurface. The results of subsurface mapping of the Tanimbar Islands based on the results of Joint Inversion modelling have found a geological structure pattern in the form of a fold thrust belt due to the Banda Arc subduction zone. In section A-A', there is a sequence of fold thrust belt with 10 structural patterns, including 6 structures in the northwest-southeast direction and 4 structures in the northeast-southwest direction. In section B-B' there are 9 structural patterns in the northeast-southwest direction. High anomalies obtained density values ranging from 2.77 - 2.81 gr/cm3 and susceptibility ranging from 0.00125 - 0.0013 SI are thought to be caused by high basement in the form of volcanic rocks, while low anomalies obtained density values ranging from 2.45 - 2.49 gr/cm3 and susceptibility ranging from 0.0008 - 0.00085 SI are thought to be caused by thick sedimentary layers of the Batimafudi Formation.

Published: September 2023

The use of e-learning platforms during the Covid-19 pandemic and in the context of facing the era of the industrial revolution 4.0 is a must in almost all levels of education, especially in universities. Many efforts have been made and implemented in order to apply these demands, for example by developing applications that are expected to help organize the digital learning process. The method used in obtaining information is a quantitative method using an instrument, namely a questionnaire (distribution of questionnaires) through the Google form application. The subjects in this study were UNP students in the Fundamentals of Education course in the July-December 2020 semester. Based on the research results, information was obtained regarding the policy evaluation of the use of a full online (online) e-learning system that could be categorized as good and effective, but it needs to be improved in several parts, for example: effectiveness, content, interaction patterns, understanding of the material, network access, large/expensive data packets when using video conference collaborating with the platform e-learning. The element of effectiveness/efficiency of online learning as many as 23.5% of respondents considered it less effective / efficient, meaning that there were still gaps in the fully online policy implemented by universities in this case, namely UNP.

Creativity is the potential of every individual that can be studied, processed, explored and developed for the better, not an innate talent and trait born in a person. In the implementation of learning, Creativity has an essential role in creating more active, fun, exciting learning and facilitates learning. Teacher creativity is the ability to find thoughts about ideas and ideas in solving a problem related to educational science. Creative teachers will continue to develop exciting learning to improve quality, improve materials, use methods, use media and manage classrooms. Especially during the current COVID-19 pandemic, a teacher is required to create exciting and fun learning. The Covid-19 pandemic that has occurred throughout the world, including Indonesia, involves implementing distance learning as instructed by the Ministry of Education and Culture to continue learning during this COVID-19 outbreak. Therefore, teachers at all levels of education must make new learning plans related to distance learning. Likewise, the teaching carried out at SMP Negeri 4 Subah, an area in the red zone of the spread of the COVID-19 outbreak, requires learning to be carried out online. This research was conducted at SMP Negeri 4 Subah with a qualitative approach or descriptive field research. The results show that teachers at SMP Negeri 4 Subah are ready to carry out online learning by utilizing media or applications that can support online learning to keep it exciting and fun, including using WhatsApp, Google Classroom, Google Form, Zoom Meeting, Email and other applications on when delivering subject matter, giving assignments and carrying out tests.

In the knowledge dimension aspect, most HOTS materials belonged to factual knowledge. While in cognitive aspect, most HOTS questions belonged to remembering level.  It can be concluded that the majority of EFL materials in Geschool belonged to lower-level thinking skills, particularly remembering (cognitive dimension) of factual knowledge.  Therefore, big efforts should be addressed to escape from such low level of knowledge.
New Zealand Religious Groups’ Responses to the Christchurch Terror Attacks
Authors: Rivera Catherine , Oxholm Theis , Hoverd Wil
Published: September 2023

This article explores how New Zealand religious leaders and their communities responded to the 15 March 2019 Christchurch mosque shootings. This article analyses qualitative data, drawn from leaders across New Zealand’s diverse religious communities, specifically including minority religions and the non-religious. It utilizes a two-time-period qualitative data collection methodology combining material drawn directly after the attacks with interviews subsequently conducted one year later with a diverse sample of religious leaders (n=14). We offer three findings: 1) Immediate religious community responses to the Christchurch mosque shootings, 2) Religious community reactions and reflections on the state response, and 3) Inclusive and exclusive religious framing of the mosque victims’ Muslim identity. Our findings demonstrate that New Zealand religious communities were universally appalled by the Christchurch mosque attacks, in terms of its human impacts on the Muslim community, but in some cases the recognition and legitimation of the victims’ religious identity were contested.
Hans Mol and the Empirical Study of Australian Religion
Authors: Singleton Andrew
Published: September 2023

This article examines the Religion in Australia survey (RIA) that was conducted in 1966. Led by sociologist Hans Mol, this was the first major survey of religion in Australia. Mol’s findings were published in his landmark monograph, Religion in Australia (1971), which is arguably the most comprehensive work ever written on the religious lives of Australians. To reveal the varieties of Christian belief and practice, Mol developed a typology that categorised Australians into different kinds of believers (not unbelievers). However, Mol’s efforts were circumscribed by the computational, statistical and practical limitations of the time, and he barely engaged with the secularisation literature or other social developments. Using cutting-edge statistical procedures (latent class analysis), this article re-examines Mol’s empirical study of Australian religion and offers deeper and more complex insights into the ‘religious patterns of the Australian population’ in the 1960s. The article highlights Mol’s pioneering empirical sociology of religion and the contribution that he made to the understanding of post-war religion in Australia.
Respect on Social Media:
Authors: Shu Xu Cheah , Jin Lim Soo
Published: September 2023

The COVID-19 pandemic has brought the world to a halt with lockdowns and restricted public gatherings. This has resulted in religious organizations relying on social media to reach out to and stay in touch with their members. The current gauge of success of a social media community is based on the engagement and participation of its members—in liking, sharing, and generating content for the group. This article examines the online behaviour, through the use of online intensive interviews, of twenty-one young adults aged between 18–30 who were members of an online Buddhist Facebook group (BLIA YAD) during the pandemic. This article attempts to provide insight into the role of respect and effect on the online participation and engagement of its members. Respect being a crucial part of the belief system of the faithful has led to low levels of engagement and participation on the organization’s social media. This study examines the role that respect plays amongst the participants in the context of Malaysia where religion conservatism is at odds with the freedom of expression that is prevalent on most social media platforms.

‘A Rose by Any Other Name?’
Authors: Kozlovic Anton Karl
Published: September 2023

The field of religious dialogue is fraught with a bewildering variety of names to describe essentially four basic interrelationships, namely: (a) interreligious dialogue, (b) intrareligious dialogue, (c) interideological dialogue, and (d) intraideological dialogue. These taxonomic relationships, other naming variants, and a survey of evaluative dialogue labels were identified and briefly explicated. It was concluded that academic precision requires a more thoughtful consideration of what one actually means by “dialogue”. General nomenclature recommendations were proffered.

‘Where does Granny live?’ The role of test questions in conversational remembering between mothers and their children with developmental language disorder
Authors: Hughes Lucy , Corrin Juliette , Newton Caroline , Best Wendy
Published: September 2023

Background: Parent–child conversations form the primary context for language acquisition. This article investigates the role of test questions (TQs) in shaping turn construction opportunities for children with language disorder during conversational remembering with their mothers. Method: Video-recorded data from two mother–child dyads were evaluated using conversation analysis (CA). A recently proposed framework was used to examine TQ sequences initiated and developed from both a knowing and unknowing epistemic stance. Results: Our findings suggest that turn-taking and turn construction opportunities for the child are shaped by: congruity of mother's epistemic stance within and across turns; positioning of mother's remembering as shared, joint, or collaborative; availability of language elements in mother's turn for the child's next turn construction; and mother's expectation of competence display by the child in their following turn. Discussion and conclusion: Our data reveal the potential of CA to inform understanding of TQ patterns and interventions which support parents in the refinement of conversation skills to help children with language disorder.
Building Social Distances in Neopalatial Crete
Authors: Rapakko Jonas
Published: September 2023

This study compares the accessibility of the Minoan Neopalatial (ca. 1750–1490 bc) Palaces of Knossos, Phaistos, Malia, Zakros and Galatas in central and eastern Crete. The study seeks to interpret the sites’ social meaning based on analytical observations of their spatial organisation, using cost-surface analysis functions available in Geographical Information System (GIS) software. The article focuses in particular on assessing the distinct accessibility patterns provided by the different, supposedly main entrances to the sites; on the effect of ‘lengthening access’ and its social implications in the Minoan built environment; and on the gendered use of space in the hall systems of the Palaces.
Spanish-speaking parents’ experiences after English-only and Spanish-only interactions with their children
Authors: Morales Maria , Alfano Alliete R. , Medina Angela M.
Published: September 2023

The purpose of this study is to explore L1 versus L2 (or English-only versus Spanish-only) language use during play activities with their children from the perspective of the immigrant parent. Nine primarily Spanish-speaking parents of typically developing children 12–46 months of age were interviewed after completing play activities with their children in English and in Spanish. To develop participant language proficiency profiles, descriptive data were collected and analysed using clinical language tools. Data on participants’ perceptions of language were collected using semi-structured interviewing and analysed using thematic analysis procedures. Participant–child forced language interaction data were collected during play activities and analysed using linguistic analysis software. One major theme (forced English as a barrier to authentic communication) and three subthemes (child did not understand parent, parent felt uncomfortable and code-switching) were found based on their experiences. The results from this study show that these Spanish-speaking parents who are learning English feel more comfortable speaking to their children in their native language. The lack of comfort and proficiency in English had a negative impact on parents’ language output in quality and quantity which has implications for the children's overall language exposure. The information obtained from this study may be used to educate professionals working with Spanish-speaking parents that are learning a second language.
Abbreviations in social media communication
Authors: Amaro Raquel , Reis Maria Leonor
Published: September 2023

Abbreviations form a large part of current social media communication, where messages are conditioned by time and space, allowing for fast communication in a limited space. Many abbreviations do not have an impact on language data, since they are just an alternative form of their corresponding non-abbreviated expression. However, they are a productive source of neologisms. This article presents an analysis of the trendy abbreviations used in social media by Portuguese youth and the associated neology phenomena. The lexicographic treatment of these abbreviations in the context of planning a dictionary designed to help people cope with these new trends is discussed, with a particular emphasis on neologisms. In considering the target audience and the main focus of users’ needs and profiles in modern lexicography, the decisions presented cover general options for data selection, and for the definition and design of the microstructure and macrostructure of the dictionary.

Procedural conditions for admitting evidence from the testimony of a crown witness in Polish criminal procedure
Authors:   Instytut Nauk Prawnych Uniwersytet Rzeszowski, Bajda Karol
Published: September 2023

The procedural criminalistic institution of a crown witness is one of the most effective mechanisms for combating organized crime at the disposal of the justice system. The aim of this article is to analyse Article 3 of the Crown Witness Act, which presents a collection of obligatory and facultative conditions that a suspect must fulfil in the process of applying for the status of a crown witness. This provision can be seen as a complement to the definition in Article 2 of the aforementioned Act. In the text, the author discusses the issue of the content of statements made by the accused, who is seeking to obtain the status of a crown witness, as well as the mechanism that obliges them to provide testimony in court. Additionally, the facultative condition of the suspect's commitment to returning any financial benefits derived from the crime or fiscal offense and compensating for damages incurred as a result of its commission is explored. The considerations are based on available literature and current legislation. The author also refers to court rulings concerning the discussed provisions and the line of jurisprudence related to the assessment of testimony provided by a crown witness.
Wpływ nauki starożytnej Grecji na rozwój logiki
Authors:   Instytut Nauk Prawnych Uniwersytet Rzeszowski, Pelczar Aleksandra
Published: September 2023

The role of logic in everyday life is of incredibly significant importance. Since ancient times, great thinkers such as Socrates, Plato, Aristotle, and Zeno of Elea have shown an interest in it. The present state of logic is the result of a prolonged process of evolution. The ancient Greek times played a pivotal and immensely foundational role in shaping it. From the 6th to the 4th century BCE, the foundations of logical thinking were born, which had a far-reaching impact on the later development of this field. The aim of this article is to present the significant influence of ancient Greek philosophy on the development of the science of logic. Due to the extensive thematic scope, the author has selected key issues that, in her opinion, had the most impact on the development of this science. This work delves into essential elements such as Socrates' methods, syllogism, and the reductio ad absurdum strategy, all of which lead to a deeper understanding of the fundamentals of logic.
Management of Posterior Mandibular Bone Cavitation for Dental Implant Placement: A Case Series of 5–24 Years of Follow-Up
Authors: Park Won-Bae , Lim Hyun-Chang
Published: September 2023

Focal osteo-cavitation in the posterior mandible is a condition that clinicians do not know well. Inadvertent implant placement in such areas may result in nerve damage due to abrupt drill penetration and implant displacement in the medullary space. In the present case series, focal osteo-cavitation was managed with the following procedures: (1) undersized drilling, (2) gentle trabecular curettage, (3) bone substitute material grafting in the cavity, and (4) long healing period for osseointegration. In all cases, a sudden loss of drilling pressure immediately after passing through the thin cortical layer revealed focal osteo-cavitation. Following undersized drilling and gentle trabecular curettage, the bone substitute material was packed into the cavity with care not to press the inferior alveolar canal. Implant placement was subsequently performed. Despite a lack of primary implant stability in 3 of 4 cases, all implants were successfully osseointegrated after 6–9 months. Over 5–24 years, all implants functioned well.

Authors: Tur Merve , Sarıbaş Ebru
Published: September 2023

The aim of this study to determine the gingival phenotype around dental implants and the clinical evaluation of the existing phenotype in relation to the tissue health around the implant. 202 dental implants applied to 60 individuals who applied to our service and had at least one implant in the mouth, whose prosthetic restoration was completed at least 1 year ago, were included. The effects of keratinized mucosa width (KMW) and gingival thickness (GT), which form the gingival phenotype, on clinical periodontal parameters were evaluated with the obtained data. The implants included in the study; 115 implants were found to have adequate, and 87 implants had insufficient KMW. At the same time, the GT around 74 implants was found to be thick, and the GT around 128 implants was found to be thin. The KMW of those with thin GT was found to be lower than those with thick GT. Plaque index (PI), gingival index (GI), bleeding on probing (BoP), probing depth (PD), gingival recession (GR), and suppuration (SuP) were found to be low in those with adequate KMW, GI, BoP, PD, GR, and SuP were found to be low in patients with thick GT, but there was no significant difference between GT and PI. KMW and GT were associated with peri-implant tissue inflammation and GR. In order to maintain the health of the peri-implant tissues, it is recommended to have a KMW of at least 2 mm and a thick gingiva.
The potential role of Indigofera zollingeriana as a high-quality forage for cattle in Indonesia
Authors: Antari Risa , Ginting Simon P. , Anggraeny Yenny N. , McLennan Stuart R.
Published: September 2023

Ownership of cattle in Indonesia is dominated by smallholder farmers, who rely heavily on low-quality mature grasses and crop residues as animal feed. Forage tree legumes (FTLs) provide a practical and profitable option for supplying nutrients limiting cattle growth and reproduction, especially during the dry months. Indigofera zollingeriana is a tall, high-yielding plant under investigation as feed, which can produce edible plant material exceeding 4 t dry matter (DM)/ha/harvest, when cut every 68 days. I. zollingeriana is adapted to a relatively wide range of climatic conditions and soil-types, with notable high tolerance of acidic soils. Forage quality is high, with high crude protein (265 g/kg DM average) and low fiber (367 g neutral detergent fiber/kg DM) concentrations and high in vitro DM digestibility (72.6%). It contains no identified anti-nutritional compounds but concentration of indospicine, a recognized toxic contaminant in some species of Indigofera, is currently unknown. Information on animal responses to feeding I. zollingeriana is limited, especially for cattle, but research suggests growth responses in goats are comparable with those for other available FTLs. Research to date suggests I. zollingeriana could be a valuable addition to FTLs currently available in Indonesia, especially for acidic soils, but further information is required on performance on saline soils, persistence under regular harvesting, indospicine status, acceptance by cattle and effects on their productivity.

Published: September 2023

Tropical pasture grasses and legumes can be highly productive and persistent and fill the summer-autumn feed gap typical of temperate pasture systems in southern Australia. However, more information is needed on optimum temperature range for seedling emergence because this will influence sowing time recommendations. A replicated field experiment was conducted at 5 locations in New South Wales over a 12-month period to determine the optimum temperature for emergence of a range of tropical species: Rhodes grass (Chloris gayana Kunth), Makarikari grass (Panicum coloratum L. var. makarikariense Gooss.), kikuyu grass (Cenchrus clandestinus (Hochst. ex Chiov.) Morrone), digit grass (Digitaria eriantha Steud.), panic grass (Megathyrsus maximus (Jacq.) B.K. Simon & S.W.L. Jacobs), paspalum (Paspalum dilatatum Poir.), Urochloa hybrid (Urochloa decumbens × U. ruziziensis × U. brizantha), 2 cultivars of Desmanthus virgatus (L.) Willd. (cultivars ‘Marc’ and ‘JCU2’), D. bicornutus (S. Watson), D. leptophyllus (Kunth) and D. pernambucanus (L.) Thell.). Rhodes grass emerged satisfactorily over the longest time across all sites, exhibiting the greatest temperature range over which emergence occurred, while Makarikari grass and panic grass had the narrowest temperature range for emergence. The temperature for 50% emergence differed between the tropical species and whether the soils were warming or cooling. Rhodes grass had the lowest 50% emergence temperature (17 °C) while paspalum had the highest (22 °C). Results showed that temperature for 50% emergence is a useful indicator for determining sowing time in warming soils.

Chemerin is a multifunctional adipokine associated with systemic inflammation, angiogenesis, and oxidative stress. Emerging evidence suggests a potential link between chemerin and the pathogenesis of preeclampsia (PE). In this systematic review and meta-analysis, we aimed to evaluate the serum chemerin levels in women with PE. A systematic search was conducted across Medline, Web of Science, and Embase databases from inception until April 15, 2023, to identify studies comparing serum chemerin levels in pregnant women with and without PE. A random-effects model was employed to pool the results, accounting for heterogeneity. Thirteen datasets from 10 observational studies, encompassing 832 women with PE and 1298 healthy pregnant women, were analyzed. The pooled findings indicated a statistically significant elevation in serum chemerin levels in women with PE compared to controls (mean difference [MD] = 89.56 ng/mL, 95% confidence interval [CI] 62.14 - 116.98; P < 0.001; I2 = 87%). The subgroup analysis revealed consistent findings across studies that measured chemerin levels before or after the diagnosis of PE, studies that did or did not match the body mass index (BMI), and studies with varying quality scores (P values for subgroup differences were all > 0.05). Compared to controls, women with severe PE exhibited a significantly greater increase in serum chemerin levels than those with mild PE (P value for subgroup difference = 0.007). Additionally, meta-regression analysis results suggested that the mean BMI of the included pregnant women might positively modify the difference in circulating chemerin levels between women with and without PE (coefficient = 8.92; P = 0.045). In conclusion, this meta-analysis suggests a positive correlation between elevated serum chemerin levels and PE diagnosis in comparison to pregnant women without the condition.

Authors: KARTAL Levent
Published: September 2023

In this study, crystalline Co2B powder production was carried out by a one-step carbothermal reduction method starting from cheap, easily accessible oxide-based materials. Firstly, to determine the carbothermic CoxB formation conditions, the decomposition temperatures of the raw materials were analysed by TG/DTA, and the temperature-varying Gibbs free energies of the expected reactions were calculated. Then, Co2B production was carried out at constant CoO/B2O3/C (3.22/1.5/1.3) weight ratios at temperature (1273-1473 K) and time (30-270 min). scanning electron microscopy (SEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM) were used to characterize the particles. XRD results showed that reaction temperature and time are the primary control on CoxB formation. Single-phase crystalline Co2B particles with crystallite sizes of 88 nm were successfully produced at 1473 K and 150 min. The permanent magnetization, saturation magnetization, and coercivity values of Co2B particles were defined as 16.58 Oe, 35.361 emu/g, 0.501 emu/g, respectively

Moringa leaves are used as feed to increase the intensity of estrus. It is assumed that the positive effect on the Moringa leaves is due to the presence of vitamin A. This study aims to see the response of vitamin A as a supplement feed to the reproductive performance of beef cows including estrous intensity, number of follicles, follicle diameter, and pregnancy rate. The research was conducted in September-November 2022 in Lappariaja District, Bone Regency, South Sulawesi Province. 10 cows were used which were divided into 2 groups, each group consisting of 5 cows. Group 1 was the control group without vitamin A and group 2 was supplemented with vitamin A. The data on estrus intensity, number of follicles and pregnancy rate obtained were processed using the Chi-square analysis of 2x2 contingency tables. If the Chi-square test does not meet the requirements, the formula used is the Fisher exact test. While the data on the diameter of the follicles were analyzed by ANOVA test. The results of the research data showed that supplementation of vitamin A had a significant difference (P<0.05) on the intensity of estrous. Meanwhile, the results of the chi-square test on the number of follicles and pregnancy rates (P>0.05) showed that there was no significant difference. Likewise, the ANOVA test on follicle diameter between control cows and vitamin A treated cows did not have a significant difference. Although in this study it did not affect the number of follicles, follicle diameter and pregnancy rate. However, it has an economic effect of 20% on the pregnancy rate in the livestock industry scale.

The study aimed at identifying novel bioactive natural compounds from intertidal marine gastropod Planaxis sulcatus (Born, 1778) Collected from Karwar coast, West coast of India. Crude methanolic extract of intertidal marine gastropod Planaxis sulcatus was tested for preliminary zoochemical screening using standard methods to determine the presence of different chemical compounds: The crude extract was analysed using GC-MS to identify the bioactive components. The disc diffusion method was used to conduct an antibacterial experiment. Accordingly, the inhibition zone around the disc impregnated with gastropod extract was used to test the antibacterial activity. By using the micro broth dilution technique, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the extract were determined. Standard zoochemical testing of the Planaxis sulcatus whole body extract revealed the presence of steroids, alkaloids, flavonoids, glycosides, tannins, and saponins. A total of 130 chemicals were identified as the bioactive components in the extract using GC-MS. Seventeen of these compounds have antimicrobial properties while eleven of these compounds have antioxidant properties, six of these have anticancer properties based on published literature. Some of the other compounds also suggest biological activities other than antimicrobial, antioxidant and anticancer which indicates potential biomedical applications. The gastropod extract showed noteworthy antibacterial activity with minimum inhibitory zone of 12 mm against Pseudomonas aeruginosa and maximum 30 mm against Staphylococcus aureus at 40 μg/ml concentration. The Minimum Inhibitory Concentration (MIC) was found to be 1.72 μg/ml, 1.87μg/ml, 1.99 μg/ml, and 1.87 μg/ml against Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonia, and Escherichia coli respectively. The MIC value decrease with higher concentration of methanol extracts than that of the pure antibiotic. As a result, Klebsiella pneumonia exhibits higher MIC values and MIC-CFU (214). The tissue extract of Planaxis sulcatus possess bioactive compounds that have potent antibacterial effect

Published: September 2023

Phishing emails pose a severe risk to online users, necessitating effective identification methods to safeguard digital communication. Detection techniques are continuously researched to address the evolution of phishing strategies. Machine learning (ML) is a powerful tool for automated phishing email detection, but existing techniques like support vector machines and Naive Bayes have proven slow or ineffective in handling spam filtering. This study attempts to provide a phishing email detector and reliable classifier using a hybrid machine classifier with term frequency-inverse document frequency (TF-IDF) and an effective feature extraction technique (FET) on a real-world dataset from Kaggle. Exploratory data analysis is conducted to enhance understanding of the dataset and identify any conspicuous errors and outliers to facilitate the detection process. The FET converts the data text into a numerical representation that can be used for ML algorithms. The model’s performance is evaluated using accuracy, precision, recall, F1 score, receiver operating characteristic (ROC) curve and area under the ROC curve metrics. The research findings indicate that the hybrid model utilising TF-IDF achieved superior performance, with an accuracy of 87.5%. The paper offers valuable knowledge on using ML to identify phishing emails and highlights the importance of combining various models.
ГОРОДСКОЙ АРХИТЕКТОР ДОРЕВОЛЮЦИОННОЙ СЫЗРАНИ С. П. ЩЕРБАКОВ: НОВЫЕ БИОГРАФИЧЕСКИЕ СВЕДЕНИЯ
Authors:   Краеведческий музей городского округа Сызрань, Л. М. Куракина
Published: September 2023

В статье рассматриваются основные этапы жизни Сергея Петровича Щербакова, вошедшего в историю города Сызрани как городской архитектор (1911‒1916) и как председатель уездного исполнительного комитета (апрель‒июнь 1918 г.) в начальный период белочешского мятежа на территории Среднего Поволжья. Несмотря на значимость занимаемых должностей биографических сведений о нем было мало. Благодаря переданным правнуком С. С. Щербаковым в феврале 2023 г. Сызранскому краеведческому музею копиям личных документов, прежде всего автобиографии и личных фотографий, были в значительной степени заполнены пробелы в описании жизненного пути С. П. Щербакова. Удалось с полной достоверностью установить имена, социальное происхождение родителей; точную дату и место рождения, годы и места учебы, работы и воинской службы Сергея Петровича в дореволюционные и послереволюционные годы; определить его место нахождения в период белочешского мятежа, с позиции самого С. П. Щербакова объяснить причины его «автоматического выхода» из рядов большевистской партии. Для города Сызрани личность С. П. Щербакова трудно переоценить. На период его служения городским архитектором пришлась наиболее активная фаза градостроительной деятельности. Город был вынужден заново застроить выгоревшую в 1906 г. центральную часть, соблюдая планомерность и определенное единство стиля, характерное для того времени, как правило, эклектики и модерна. Архитектурный облик того периода сохраняется в основном и сейчас, придавая городу неповторимый образ дореволюционного купеческого волжского города. Сохранился и Дом архитектора С. П. Щербакова, являющийся памятником культурного и исторического наследия регионального уровня.
