Idiopathic nephrotic syndrome is considered the most common glomerulopathy in childhood. Approximately 70–80% of patients will have relapses of nephrotic syndrome after steroid therapy, and half of them will have frequent relapses of the disease, or will develop dependence on steroid therapy, which subsequently requires a decision on steroid-sparing therapy. Currently, there are no methods to predict a patient’s response to a drug before its prescription, and the choice of steroid-sparing immunosuppressive therapy is most often determined by the preferences of the physician, rather than the individual characteristics of the patient. In this regard, it becomes relevant to develop new strategies and approaches aimed at increasing the therapy effectiveness, reducing the frequency of relapses, and minimizing side effects of drugs. In recent years, a new term has appeared in the scientific literature — «pharmacotranscriptomics», aimed at finding RNA biomarkers to predict individual reactions based on the transcriptome profile. This modern field offers new approaches to understanding individual responses to drug therapy based on gene expression analysis and identification of factors influencing these responses. In this paper, we report data from a study aimed at determining the significance of gene expression of interest in cyclosporine metabolism, viewed as pharmacotranscriptomic markers of therapy efficacy in children with steroid-dependent and steroid-resistant nephrotic syndrome. Analysis of genes associated with cyclosporine response revealed that of the genes studied, CYP3A4 and PPIA demonstrated significant differences between patients who achieved remission and those who relapsed during therapy. This result is particularly important since we for the first time characterized the expression profile of these genes in patients receiving calcineurin inhibitors.

Water for men or water for the Gods? The caput aquae of the aqueduct of Santa Maria in Stelle (Verona)
Authors: Gangale Risoleo Davide
Published: December 2024

The hypogeum of Santa Maria in Stelle, Verona, is mainly known as a place of Christian worship,built between 4th century CE and 5th century CE. This paper traces the previous phases of the monument, through the analysis of archaeological records, ancient cartography, and historical sources, and explores the reasons for its construction and the people involved. In fact, the site was not originally a place of worship, but a service facility, acting as the caput aquae of a small aqueduct, which has been traced back to Pomponius Cornelianus, consuland curator, who lived between 2nd century CE and 3rd century CE.

Published: December 2024

Söz varlığı yalnızca bir dilde bazı seslerin bir araya getirilmesiyle kurulmuş göstergeler değil, ayrıca o dili konuşan toplumun kavramlar dünyasıdır ve bir dilin söz varlığı, o dilin tarihini aydınlatmaktadır. Bir toplumun yaşam şekliyle beraber, dini inançları, gelenek ve görenekleri de söz varlığının tespitiyle ortaya çıkar. Genel söz varlığının içerdiği ögeler ; temel söz varlığı, yabancı sözcükler, deyimler, atasözleri, ilişki sözleri, kalıplaşmış sözler, terimler, çeviri sözcüklerdir. Türkçenin söz varlığı düşünüldüğünde deyimleri bu çerçeveye koymak pekala mümkündür. Zira Türkçe, deyimler bakımından zengin bir söz varlığına sahiptir. Bir sanatçının veya yazarın da sahip olduğu söz dağarcığı ve dili kullanma yeteneği eserine yansır. İlgili bu söz varlığı da eser üzerine yapılan söz varlığı çalışmalarıyla ortaya çıkarılır. Bu çalışmada, Yaşar Kemal’in Bir Ada Hikayesi dörtlüsünün ilk kitabı olan, Ege’de yüzleri birbirine dönük milyonlarca insanın yerlerinden yurtlarından edilişinin öyküsünün anlatıldığı bir roman olan Fırat Suyu Kan Akıyor Baksana’da kullanılan deyimler incelenmiştir. Deyimler incelenirken Türkiye Türkçesi’nde yer alan deyimlerin ortaklık veya farklılık arz eden kısımlarını tespit edebilmek için Türk Dil Kurumu tarafından hazırlanan, dijital ortamda sunulan Güncel Türkçe Sözlük’e başvurulmuştur. Güncel Türkçe Sözlük’te olmayan deyimler için ise Ömer Asım Aksoy tarafından hazırlanan Atasözleri ve Deyimler Sözlüğü –II Deyimler Sözlüğü’nden faydalanılmıştır. Öncelikle eserde geçen deyimler alfabetik olarak sıralanmış, ardından kullanılan anlama değinilmiş ve metinde ilgili deyimle bağlantılı olarak kullanılan örneklere yer verilmiştir. Hem iyi bir geleneksel anlatıcı hem de halkın sesi durumunda olan Yaşar Kemal’in kullandığı dil halkın kullandığı doğal dildir. Bu bakımdan, düşünüldüğünde ilgili romanda yer alan deyim sayısı da fazladır. İlgili deyimlerden bazıları Güncel Türkçe Sözlük’te aynı şekilde ve aynı anlamda geçmekte; bazıları şekil açısından ortak, anlam açısından farklı bir durum arz etmekte, bazıları ise hem şekil hem de anlam özelliği itibariyle tamamen farklı bir manzara sunmaktadır. Bu açıdan düşünüldüğünde, bu çalışma ile deyimlerle ilgili güncel söz varlığımıza katkı sağlamak mümkündür. Çalışma ayrıca, ünlü roman yazarının ve kimilerine göre “tarih anlatıcısı”nın dönemindeki söz varlığının tespit edilmesi ve günümüz söz varlığı ile karşılaştırma yapılabilmesi bakımından da önemlidir.
DİYORLAR Kİ’DE EDEBİYAT TARİHİNİN MİLLÎLİK EKSENİNDE YORUMLANMASI VE TANZİMAT EDEBİYATININ ARAÇSALLAŞTIRILMASI
Authors: Atik Egem
Published: December 2024

Ruşen Eşref Ünaydın’ın Diyorlar Ki adlı kitabı, 1916-1918 yılları arasında on sekiz önemli yazarla yapılan röportajların derlemesidir. Bu röportajlar çeşitli dergi ve gazetelerde yayımlanmış, 1918’de kitap olarak basılmıştır. Röportajlarda Abdülhak Hamit Tarhan, Halit Ziya Uşaklıgil, Halide Edip Adıvar, Ziya Gökalp ve Ahmet Haşim gibi dönemin ünlü yazarlarına eski edebiyat, Tanzimat edebiyatı, Servet-i Fünûn edebiyatı, milli edebiyat ve edebiyatın geleceği hakkında beş ana soru yöneltilmiştir. Ruşen Eşref’in soruları ve yazarları yönlendirme biçimi, kitapta çizgisel ve ilerlemeci bir edebiyat tarihi oluşturmanın amaçlandığını gösterir. Bu çalışma, Diyorlar Ki’nin Tanzimat’tan itibaren milli bir kimlik oluşturmak için ulusal bir edebiyat tarihi kurma çabasının bir parçası olduğunu öne sürmektedir. Röportajların milli edebiyatın etkili olduğu bir dönemde yapılmış olması, kurgulanan edebiyat tarihinin millilik ekseninde şekillendirilmesinde önemli bir rol oynamıştır. Makalede bu nedenle, milli edebiyat yazarlarının röportajlarının incelenmesine ağırlık verilmiştir. Bu çerçevede öncelikle, milliliğin edebi eserler ve dönemler için bir değer ölçütü haline gelmesi ele alınmakta, Ruşen Eşref Ünaydın’ın yönlendirici soruları ve yazarların yanıtları aracılığıyla millilik ekseninde bir kurgu oluşturulduğu tespit edilmektedir. Röportajlar millilik anlayışının, sanatlı anlatımdan uzaklaşmayı, yabancı edebiyatların etkisinden kurtulmayı, dilde sadeleşmeyi ve halka yönelmeyi içerdiğini açığa çıkarmaktadır. Bu nitelikler göz önünde bulundurularak kurgulanan ulusal edebiyat tarihinde kabul gören ve görmeyen eser ve dönemlerin ayırt edilmesinde, Tanzimat yazarlarının ürettiği söylemin belirleyiciliği olduğu anlaşılmaktadır. Makalede daha sonra, Tanzimat’tan itibaren üretilen edebi metinleri milli kaygılar taşıyan homojen bir ulusal edebiyat olarak yorumlayan Fuat Köprülü röportajına odaklanılmakta, Tanzimat edebiyatı ve milli edebiyattaki millilik algıları arasındaki farkların silikleştirilmesi sorunsallaştırılmaktadır. Son olarak, Diyorlar Ki’de röportaj veren milli edebiyat yazarlarından Ziya Gökalp’in Tanzimat edebiyatını olumsuzlayarak milli edebiyatın yüceltilmesini ve daha da güçlenmesini mümkün kıldığı öne sürülmektedir. Makaledeki analiz, edebiyata milli bir nitelik kazandırmayı hedefleyen bakışın yeri geldiğinde son derece pragmatik tercihler yapabildiğini gözler önüne sermektedir.
Evolution of Perceived Vulnerability to Infection in Japan During the COVID-19 Pandemic
Authors: Ayumi Ikeda , Sasaki Kyoshiro , Yamada Yuki
Published: December 2024

The global pandemic triggered by the emergence of the highly contagious disease known as COVID-19 has brought about substantial shifts in the everyday lives of individuals across the globe. The present study aimed to elucidate the evolution of perceived vulnerability to disease (PVD) before, during, and after the pandemic by comparing PVD levels in Japan from 2018 to 2023. We analyzed longitudinal changes in perceived vulnerability to disease (PVD) using data collected in Japan across five time points (2018, 2020, 2021, 2022, and 2023). Data from 2018, 2020, and 2021 were obtained from publicly available datasets, while we collected data from 2022 and 2023 for this study. The results showed that although PVD (consisting of perceived infectability and germ aversion) increased significantly in the early stages of the pandemic in 2020, it decreased each year thereafter. By 2023, perceived infectability had declined to a level lower than in 2018, while germ aversion, although lower than in 2020, remained higher than pre-pandemic levels. This finding indicates a tendency to negative estimate one's resistance to infection during the pandemic, while after the crisis abated, individuals tend to assess their resistance to infection more positively. In contrast, germ aversion continued to show a lasting effect, remaining elevated even three years after the peak. These results suggest that the pandemic may have introduced a dual effect: in addition to heightening sensitivity to infection prevention, it may have cultivated a sense of “overconfidence” regarding infection resistance. This overconfidence potentially contributes to a more relaxed attitude toward infectious disease risks, as individuals perceive themselves as resilient after enduring an unprecedented public health crisis.

Published: December 2024

The synthesis of polymer ionic liquids and ionene-type ionic liquids has been optimized through the implementation of a rigorous scientific and methodical approach. The feasibility of utilizing an integrated "polymer–monomer" strategy for synthesizing polymer ionic liquids has been demonstrated. The concentration-dependent viscosity of ionene-type polymer ionic liquids in solutions was analyzed, and the influence of their chemical nature was elucidated. Practical recommendations have been developed to address the scientific and applied challenges associated with creating new ionene-type polymer ionic liquids that exhibit high ionic conductivity while maintaining a liquid state over a wide temperature range. These findings aim to solve pressing issues in chemical technology.

Using developed equipment and a methodology for experimental studies on the workability of the grain composition of three-fraction charges under load in a cylindrical container during vibrational impact after a series of blows from a compactor, the optimal fraction content was determined to meet the conditions for achieving a high degree of compaction. The analysis of experimental results identified charges with high bulk density and compaction coefficients, highlighting the following optimal fraction composition for further research (wt.%): 20–50% of 5–10 mm granite gravel, 25–40% of 2–5 mm granite gravel, and 25–40% of 0–0.3 mm sand. All experimental results were processed using the simplex-lattice method of mathematical modeling, applying the Scheffe methodology to derive regression equations in the form of fourth-degree polynomials. The analysis of graphical interpretations of the regression equations revealed patterns in bulk density changes under load and the compaction coefficient of three-fraction charges depending on their composition.

The influence of solid-state polycondensation conditions on the rheological properties of polyethylene terephthalate was determined. Mathematical models describing the dependence of the melt flow rate of both virgin and recycled polyethylene terephthalate on the time and temperature of the solid-state polycondensation process were developed. A correlation between the melt flow rate and the average molecular weight of polyethylene terephthalate was demonstrated. Experimental studies showed that conducting solid-state polycondensation of recycled polyethylene terephthalate at temperatures ranging from 1300C to 1600C for 3 hours produces polymeric materials with higher molecular weight and, consequently, improved performance properties.

The development of hypersonic unmanned aerial vehicles (UAVs) for aerospace systems presents ambitious challenges for scientists and engineers. Extreme flight conditions, such as ultra-high speeds and significant aerodynamic heating, necessitate the creation of new materials capable of withstanding such loads. One of the most promising materials for constructing hypersonic UAVs is carbon fiber-reinforced polymer based on bisphenol nitrile. This material exhibits high thermal resistance, chemical stability, and excellent mechanical properties. Utilizing bisphenol nitrile combined with carbon fibers has enabled the production of composite materials that can operate at temperatures exceeding 3000C, far surpassing the capabilities of traditional polymer matrices. To assess the suitability of the developed carbon fiber-reinforced plastic for hypersonic UAV applications, comprehensive studies of its physical, mechanical, and thermal characteristics were conducted across a wide temperature range from 20 to 3000C. The obtained results provided a detailed characterization of the composite and allowed for comparisons with other high-temperature composite materials. The developed carbon fiber-reinforced plastic based on bisphenol nitrile binder shows great promise for constructing hypersonic UAVs. Its high thermal resistance, combined with excellent mechanical properties, makes it suitable for use in the extreme temperature conditions typical of hypersonic flight.

This work demonstrates that the transport properties of various organic substances in the gas phase, such as viscosity and thermal conductivity coefficients, can be estimated with acceptable accuracy by using 1D-QSPR models, which allow for the prediction of the studied property based solely on the chemical composition of the molecule. Here, we studied the transport properties (viscosity coefficient and thermal conductivity coefficient) of organic compounds for sufficiently representative database including approximately 5,000 carbon-, halogen-, oxygen-, nitrogen-, and sulfur-containing compounds. Using a simplex approach for modeling molecular structure and machine learning methods, such as multiple linear regression (MLR) and random forest (RF), adequate 1D QSPR models for the transport properties of individual substances in the gas phase were developed for the formed databases. Analysis of the influence of certain structural and physicochemical factors on the studied transport properties of organic compounds was carried out. Based on the developed 1D RF QSPR models, a computer expert system for predicting the viscosity coefficients and thermal conductivity of new substances was created.

Treatment of styrene-divinylbenzene sulfonated cation exchangers with a small amount of thionyl chloride prior to reaction with chlorosulfonic acid significantly facilitates the production of sulfochlorides from polymeric sulfonic acids and their salts. Polymeric sulfochlorides were synthesized by sequential treatment of gel and macroporous styrene-divinylbenzene cation exchangers in Na and H forms with thionyl chloride and chlorosulfonic acid. Transformation of these sulfochlorides into sulfamides via reaction with ammonia, followed by treatment with gaseous chlorine, yielded polymeric sodium N-chlorosulfonamides with an active chlorine content exceeding 15%. Consequently, the conversion rate of the starting material to polymeric sodium N-chlorosulfonamide was enhanced from 25–35% to 45–55%. The optimal ratio of reagents per 100 g of starting material was determined to be 10 g of thionyl chloride and 120–150 g of chlorosulfonic acid, with a reaction duration of 4–5 hours. It was confirmed that the type of initial cation exchanger (Na or H form) has no significant effect on the final outcome.

This article is devoted to studying the properties of the new Zr–Ti–Nb alloy and comparing it with the well-known Ti–Al–V alloy (ВТ-6, Grade 5 analog). The properties were analyzed through chemical composition determination and corrosion resistance assessment. The Zr–Ti–Nb alloy does not contain the toxic impurities present in the Ti–Al–V alloy, specifically aluminum and vanadium. Structural studies were conducted to identify the phases (X-ray diffraction analysis) and their composition using scanning electron microscopy. The microstructure and phase composition of the Zr–Ti–Nb alloy indicated a uniform distribution of elements throughout the alloy. The wetting angle of the Zr–Ti–Nb alloy with an oxide layer is significantly smaller than that of the Ti–Al–V alloy, suggesting greater hydrophilicity. Physical research methods included determining density, reflectivity, and electrical conductivity. Mechanical properties were examined by determining the elastic modulus, strength limit, yield strength, longitudinal elongation, transverse contraction, and microhardness. Notably, the elastic modulus of the Zr–Ti–Nb alloy is 26.4 GPa, similar to that of cortical bone, in contrast to the Ti–Al–V alloy, which has an elastic modulus of 110–140 GPa. The obtained data indicate that the superior chemical and mechanical properties of the Zr–Ti–Nb alloy make it suitable for medical applications.
Adsorption of oleic acid on AV-17-8 anion exchange resin

Published: December 2024

Adsorption of oleic acid on AV-17-8 anion exchange resin from a sunflower oil solution is studied. It has been established that preliminary drying of the adsorbent accelerates the completion of the oleic acid equilibrium concentration and increases the acid adsorption degree. An increase in the adsorbent amount enhances the degree of oleic acid adsorption over the entire temperature range studied. An increase in temperature also raises the degree of oleic acid adsorption when using both air-dry anion exchange resin and pre-dried adsorbent. The experimental results are analyzed using Langmuir, Freundlich, and Dubinin-Radushkevich adsorption models. The oleic acid adsorption is satisfactorily described by the Langmuir adsorption equation. According to the values of the adsorption constant calculated by the Freundlich model, it is established that the adsorption of oleic acid on an anion exchange resin is physical. This conclusion is confirmed by the value of the mean adsorption energy calculated using the Dubinin-Radushkevich adsorption model. The thermodynamic parameters of the oleic acid adsorption on AV-17-8 anion exchange resin also are determined. The negative values of the Gibbs free energy and positive value of the adsorption entropy indicate that the oleic acid adsorption on AV-17-8 anion exchange resin occurs spontaneously.

Ceramic materials synthesized within alkali-free aluminosilicate systems are widely used as dielectrics in microelectronics, radio engineering, aviation, and rocket technologies. The addition of glass binders to these ceramic compositions significantly reduces the sintering temperature by promoting liquid phase formation at lower temperatures. This study investigates the effect of substituting SrO with BaO on the properties and structural characteristics of glasses in the SrO–BaO–Al2O3–B2O3–SiO2 system. It is found that replacing up to 20 mol.% of SrO with BaO enhances the glass-forming ability and promotes the formation of monoclinic strontium anorthite during crystallization. Additionally, strontium anorthite forms a solid substitutional solution with celsian due to the close ionic radii of Sr2+ and Ba2+ ions. This similarity in ionic size and charge ensures that the basic structural units of the glass network remain unchanged. Moreover, increasing the BaO content to 20 mol.% reduces the coefficient of thermal expansion of the glass from 7810–7 0C–1 to 7110–7 0C–1, while slightly increasing the density from 3.20 g/cm3 to 3.34 g/cm3. The volumetric electrical resistance at 3000C ranges between 1010.7 and 1011.6 ohmcm, demonstrating the excellent insulating properties of these experimental glasses. The properties of the investigated glasses allow considering them as components of dielectric composite materials that can significantly intensify sintering processes.

This study presents the results of experimental determination and theoretical calculations of the thermal effect of aluminum dissolution in alkaline solutions accompanied by hydrogen evolution. The experiments were conducted using an EK1 calorimeter, with temperature measurements recorded every 10 seconds. Potassium hydroxide solutions with concentrations ranging from 0.5 to 5 mol/L were utilized. It was demonstrated that the temperature variation curves over time, the temperature dynamics at different solution concentrations, and the aluminum dissolution rate exhibit an S-shaped profile. The rate of aluminum dissolution in aqueous alkaline solutions depends on the KOH concentration. As the KOH concentration increases from 0.5 to 2 mol/L, the thermal effect of the reaction rises. Further increasing the alkali concentration to 5 mol/L results in almost no change in the thermal effect. The thermal effect of aluminum dissolution in 3–5 mol/L sodium hydroxide solutions was found to be 1300 J/g. The experimentally determined thermal effect falls within the range of values calculated from thermodynamic data (from 1165 to 1528 J/g). The results obtained in this study can be applied to the development of relatively low-cost hydrogen production technologies.
Children's activities in health care waiting room environments : a phenomenological investigation
Authors:   , Mann Christina R.
Published: December 2024

The purpose of this study was two-fold: to develop an understanding of what children do in health care waiting room environments and to explore phenomenology as a design-research methodology. Data was collected through observations of children's activities in five waiting room settings. Observations revealed that children in health-care waiting room environments consistently exhibit certain desires: to manipulate and modify their environments, to experience enclosure and privacy in hiding places and to satisfy conflicting urges for exploration and novelty versus safety and familiarity. Interaction with people such as guardians and other children was also found to be important. From the data, a basic conceptual model was developed, and patterns were generated for designing more supportive waiting room environments for children. Merits and limitations of phenomenology as a design-research methodology are also discussed.

The feed composition was taken as the disturbance variable. The overhead composition of the column was controlled directly by the reflux flow rate. The control elements in the distillation system were analyzed. The responses with a feedback and/or feedforward control system were examined by means of a simulation program. The sampled-data control system was discussed and a control algorithm developed for a micro-processor.
An analysis of Mexican agricultural price policies : the inclusion of cross-commodity effects
Authors:   , Segarra Eduardo
Published: December 2024

Mexico's agricultural crop production has increased slower than domestic demand since 1965. The result has been a decrease in earlier agricultural crop exports and a subsequent increase in imports. Increases in domestic demand for farm products can be attributed to rapid population growth and increasing incomes for a large segment of the population. Recognizing the inability of the agricultural sector to satisfy domestic demands and the resulting high levels of agricultural imports, the Mexican government launched The Mexican Food System (Sistema Alimentario Mexicano or SAM) in 1980. Its major objectives were: (1) to achieve self-sufficiency in corn and beans by 1982, and (2) to achieve self-sufficiency in other basic crops by 1985. Due to the short time span under which these proposed goals are to be achieved, price policy has emerged as the most important tool. The primary objective of this study was to construct a theoretical model of price policy effects on production, consumption and imports which accounts for cross-commodity production influences. This approach also necessarily identifies the subsidies in consumption and production due to the price policies. Using national data for 1965-1980, corn and sorghum supply and demand equations were estimated to test for the existence of cross-commodity effects and calculate subsidies associated with SAM objectives. Emphasis was also placed on identifying the efficiency cost of the subsidized prices. Empirical results supported the expected cross-commodity influences, illustrating that an increase in the corn support price would decrease sorghum production and increase required sorghum imports. Calculations showed that raising the corn support price to reach self-sufficiency would necessitate a subsidy of approximately $53 billion pesos, of which $9.5 billion would be the efficiency cost. Study findings suggest that significant subsidies and efficiency cost will be associated with achieving SAM self sufficiency goals. Mexican policy-makers should be aware of these effects in formulating future agricultural price policies.
John Brooks Henderson as a representative of border-state public opinion
Authors:   , Merideth Dorothy McClure
Published: December 2024

"The stormy years of the Civil War and reconstruction period were years off confusion and strife in politics as well as in military affairs; fierce partisanship was the order of the day. No section of the country experienced this more than the border region, settled by people from both North and South and torn between these conflicting loyalties; Missouri furnishes an excellent example of this condition. John Brooks Henderson, the subject of this study, represented Missouri in the United States Senate during the greater part of the war between the states, and through the immediate post-war years. The climax of partisan hatreds which came with the impeachment of President Andrew Johnson marked the end of Henderson's effectual political career, for he had the courage to defy party demands and to vote for the acquittal of the Chief Executive who had earned the vituperative opposition of the Radical Republicans. The position of a border-state representative was often difficult in these years; the problems which Henderson met and tried to solve were probably typical in the experience of others of his region..."--Page [1]
Effects of constraint variation on the fatigue growth of surface flaws
Authors:   , Tortoriello Vicente
Published: December 2024

Studies have shown that fatigue growth of semielliptic surface flaws in plates is not adequately predicted solely by stress intensity factor analysis. The variation in stress field triaxiality along the flaw border must be an important factor contributing to differences between predicted and observed fatigue crack growth behavior. An analysis is formulated to examine surface flaw fatigue growth accounting for constraint variation using the concept of crack closure. The extent of crack closure is quantified for plane stress versus plane strain conditions. Changes in the geometric parameters describing flaw size and shape are studied. Applications of the analysis are compared with experiments. The use of the concept of crack closure to account for constraint variation along the flaw border of a surface flaw yields excellent results.
Frederick Buechner : an introduction
Authors:   , Brown W. Dale
Published: December 2024

American writer Frederick Buechner has published, since 1950, eleven novels and ten major works of non-fiction. The critical reception of Buechner's work has been generally problematic; his work has been undervalued, at least in part, because of his emerging preoccupation with theological issues. The tendency among critics has been to divide Buechner's work into pre-Christian and post-Christian phases. This study will attempt to avoid such diminishment of the Buechner corpus by elucidating the thread of religious preoccupation running through all of Buechner's writing. A detailed introduction to the early novels is particularly important as they illustrate Buechner's developing voice. Chapter one underscores Buechner's consonance with the themes of modernism but suggests that Buechner's first novel, A Long Day's Dying, reveals the bewilderments of its young author. Questions as to the consequences of evil and the logic of cynicism carry into the second novel, The Seasons' Difference, the subject of chapter two. The visionary Peter Cowley of the second novel becomes Buechner's vehicle to explore ambiguous questions of faith and to search for something beyond despair. The first two novels display the formative stages of religious faith without softening the shrill noises of modern life. Chapter three focuses on the third novel, The Return of Ansel Gibbs, a pivotal work growing out of Buechner's seminary tenure, conversion, marriage, and ordination. With the transformation of Ansel Gibbs, Buechner affirms emerging faith. Chapter four treats Buechner's fourth novel, Ths Final Beast, the central work in the canon. The novel connects Buechner's early work to his work of more recent years and offers a clear parallel to Graham Greene's The Power and the Glory, demonstrating Buechner's theory of embodying faith in fiction. Finally, chapter five offers an overview of the remaining fiction: The Entrance to Porlock, The Book of Bebb, and Godric. Despite great variance in style and subject matter, these works exemplify Buechner's consistent exploration of the possible affirmations growing from despair--the theme that flows through all of his writing. Taken together, the fiction of Frederick Buechner earns him a place with the important writers of his generation.
A model for the analysis of cohesion and information management in published writing in three disciplines
Authors:   , Lovejoy Kim Brian
Published: December 2024

This study proposes a model to compare cohesion and information management in samples of professional writing in three disciplines (counseling psychology, biology, and history). When tested with the chi-square procedure, the comparisons revealed significant differences in the cohesion and information management systems of the three sample passages (criterion: p [less than].01). The psychology passage had significantly higher cohesive density than the biology and history passages, with the biology passage significantly higher than the history passage. Significant differences were also found in the types of lexical ties in each passage. The psychology and biology passages were proportionately similar in the use of repetition, synonymy, and collocation, and significantly different from the history passage in the numbers of these types. The history passage used proportionately fewer repetitions and synonyms and more collocations and derivations. No significant differences were found in comparisons of the numbers of single and dual/multiple chains in the three passages, but comparisons of the relative numbers of words in single chains revealed significant differences in all except the comparison of biology and history. Of the 160 comparisons of proportional use of types of lexical ties in the themes of sentences, 77 were significant and 54 others approached significance. Of the 160 comparisons of proportional use of types of lexical ties in the rhemes, only three were not significantly different. All but six comparisons in rhemes were significantly different at the .001 level, a clear indication that there are very large differences in the way in which the authors of these three passages presented new information. These findings suggest that the descriptive model proposed in this study should be useful in comparing representative samples of writing in different disciplines and should lead to an understanding of the nature of writing that will benefit teachers of writing across the curriculum and teachers of reading in the content areas.
Der Allgemeine Soziale Dienst unter Druck
Authors: Weber Monika
Published: December 2024

Der Beitrag skizziert die fachlichen und organisationalen Grundlagen der – örtlich heterogen ausgestalteten – Allgemeinen Sozialen Dienste (ASD). Danach richtet er den Blick auf ausgewählte Merkmale, die für die Arbeit der ASD spezifisch und konstitutiv sind und zeigt auf, welche Herausforderungen damit aktuell verbunden sind. Deutlich wird, dass der ASD mehr denn je auf eine fachliche Ausgestaltung als sozialpädagogischer Fachdienst und auf tragfähige Rahmenbedingungen angewiesen ist.
Wer arbeitet im ASD? Statistische Daten zum Personal
Authors: Mühlmann Thomas
Published: December 2024

Die Frage, welche Personalausstattung im ASD angemessen ist, ist Gegenstand intensiver fachlicher Auseinandersetzungen. Auf Grundlage der amtlichen Kinder- und Jugendhilfestatistik gibt der Beitrag einen Überblick über die Entwicklung und die Zusammensetzung des Personals im ASD. Die bundesweite Personalerhebung fand bis 2014 nur alle vier Jahre statt, seitdem im Abstand von zwei Jahren. Aktuell können Daten zum Personal im ASD bis einschließlich 2020 im Zeitverlauf dargestellt werden. Erste Daten für 2022 liegen zwar inzwischen vor, allerdings sind diese aufgrund methodischer Veränderungen und zahlreicher Probleme bei der Erhebungsdurchführung noch nicht ausreichend belastbar. Der Beitrag enthält daher auch bereits veröffentlichte Inhalte (vgl. Mühlmann 2024).

Innere Beziehungsbilder und ihr Einfluss auf die Gestaltung von Beziehungen
Authors: Korpiun Michael
Published: December 2024

Der Autor beschreibt und illustriert, wie unsere Überzeugungen von uns selbst in Beziehung zu anderen dazu führen, ob wir uns auf Augenhöhe begegnen oder nicht. Gerade wenn wir uns unterlegen oder überlegen fühlen, laufen wir Gefahr, uns in unbewussten Abhängigkeitsbeziehungen wiederzufinden. Die Bewusstheit dafür kann uns helfen, uns erwachsen anders zu entscheiden und damit die Wahrscheinlichkeit für gelingende Beziehungen deutlich zu erhöhen. Damit erhalten Leserinnen und Leser Anregungen zur Gestaltung von Beziehungen auf Augenhöhe auf Basis einer relationalen Deutung des transaktionsanalytischen Konzepts der Grundpositionen.

Erklären durch Erzählen – vorgeführt an Norbert Elias’ »Soziogenese des Staates«
Authors: Schimank Uwe
Published: December 2024

Ist beim generalisierenden, nicht nur Einzelgeschehnisse betrachtenden Erkenntnisinteresse der Soziologie Erklären durch Erzählen eine methodologische Strategie? Methodologien, die in diese Richtung weisen, sind vor allem das ›process tracing‹, die ›analytic narratives‹ die ›kausale Rekonstruktion‹ und das ›mechanismische Erklären‹. Hier soll aber ein zentraler Vorläufer genauer betrachtet werden: Norbert Elias’ Rekonstruktion der »Soziogenese des Staates«, der ein ›model case‹ des Erklärens durch Erzählen hätte werden können und immer noch werden könnte. Ich gehe dabei in drei Schritten vor. Im ersten wird kurz erläutert, was es heißt, zur Erklärung eines Geschehens eine Geschichte zu erzählen, und wie sich das von anderen Modi sozialwissenschaftlichen Erklärens unterscheidet. Im zweiten und zentralen Schritt wird Elias’ ›model case‹ präsentiert und diskutiert – und zwar auf den beiden von ihm vorgeführten Abstraktionsstufen der Erklärung eines singulären historischen Geschehens und der generalisierten Erklärungsmechanismen. Der dritte Schritt knüpft dann an eine methodologische Überlegung Fritz Scharpfs an, die ein Vorgehen wie das von Elias an einem entscheidenden Punkt noch präziser expliziert.

In this research article it will provide information regarding the data engineering that utilizes automation in using SQL and BI tools to enhance the workflow of data. The automation of ETL (extraction, transformation, and loading) processes will improve the efficiency, consistency, and quality of a data pipeline. Reduced human interference in the processing of queries in SQL and the integration with BI tools streamline data processes, increase speed, and impact real-time decision-making. This automation minimizes errors and allows for scaling when dealing with large volumes of data. The informations that are presented in this research article is gathered from books, journals, articles and online websites.
Identifying what to teach: Using concepts, generalizations and driving questions
Authors: Adler Susan , Kho Ee Moi
Published: December 2024

Social studies lessons have often been criticized as being boring, just learning a list of factual details or doing meaningless activities that may be fun but do not lead to real understanding. As curricular instructional gatekeepers (Thornton, 2005), how do we select content and teach it in a meaningful way? This paper discusses how we may enhance pupil understanding through planning instruction around big ideas such as key concepts and generalizations. A conversational style of writing is deliberately used together with prompts to think and examples of how the lesson may look like, to make this paper more interactive and engaging for the reader.

Incorporating mediated learning experience in Geography Lessons
Authors: Wong Ting Wei, Esther
Published: December 2024

With the recent emphasis on 21st century competencies, inquiry-based learning has been touted as the recommended pedagogy as it attempts to move away from didactic teaching. However, an analysis of the current geography syllabus revealed three possible areas of improvement: (1) lack of intentional mediation of cognitive functions (2) lack of continuous mediation and (3) lack of emphasis on enhancing students’ dispositions in learning. From research, inquiry-based learning could be complemented by MLE, a theory developed by Feuerstein which refers to the quality interaction between the mediator and learner. Therefore, the purpose of this research paper is to explore how principles of MLE may be applied to address the aforementioned areas of improvement to enhance students’ learning in the geography classroom. Subsequently, a broad conceptualization of how MLE may be utilized to underpin the inquiry-based learning approach will be provided.
Developing a writing framework to guide students’ writing in geography
Authors: Sukimi Jamilah , Lim Samantha , Tamsir Sarifah , Tan San Pin , Wong Yi Jun
Published: December 2024

This paper examines the effectiveness of using a Writing Framework to guide students to write geographically for a level descriptor question. The Writing Framework combines aspects of Paul’s EOT (Wheel of Reasoning) with Neighbour’s Core Questions to guide students’ writing. The Writing Framework provides structure in extended writing, but more importantly encourages students to consider the importance of two geographical concepts, ‘Place’ and ‘Space’, in their essay writing. The study involved 18 Secondary 5 Normal (Academic) students. The majority of the students found the Writing Framework useful and showed an improvement in test scores. The results and student feedback highlighted the potential of the Writing Framework to help students in writing geographically.
