Published: September 2022

Calcined clay pellets are popular planting material for those who love to grow plants in pots. The calcined clay pellets consist of clay (C), phosphate rock (PR), and rice husk ash (RHA). [(1-x)(50C–50PR)-xRHA], x(RHA) = 0, 0.25, 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, and 0.65 wt% were prepared by a conventional solid-state reaction method. The samples were made into a spherical shape with a diameter of 10 mm and fired at 600℃ to 1000℃. The effect of x contents on phase formation, microstructure, and chemical properties of [(1-x)(50C–50PR)-xRHA] was studied. X-ray diffraction revealed the typical assemblages with quartz, illite, and kaolinite in all the samples. SEM images of samples showed irregular packing and a highly porous microstructure. The addition of x(RHA) contents results in porous microstructure in all the samples. The surface area and pore volume of samples increased from 8.83 m2·g-1 to 14.71 m2·g-1 and 0.938 cm3·g-1 to 0.942 cm3·g-1, respectively, with the increase of x(RHA). The density of the samples slightly decreased from 2.45±0.06 g·cm-3 to 1.94±0.05 g·cm-3, with an increase in x(RHA) contents. The capability of calcined clay pellets to immobilize plant growth-promoting fungi was then studied. The results showed that orchid endophytes, as plant growth-promoting fungi, grow well on the calcined clay pellets saturated with potato dextrose broth (PDB). Besides, all fungi can live on calcined clay pellets and stay viable for at least 35 days after inoculation. These results suggested that the calcined clay pellets could serve as planting material that enhances plant growth (via its nutrients and growth-promoting fungi) simultaneously.

Published: September 2022

Due to the extraordinary mechanical, thermal, and electrical properties of graphene, graphene oxide (GO), and reduced graphene oxide (rGO), these materials have the potential to become ideal nanofillers in the electrodeposited nanocomposite coatings. This article provides an overview of literature on the improvements of properties associated with graphene, GO, and rGO-reinforced coatings, along with the processing parameters and mechanisms that would lead to these improvements in electrodeposited metal matrix nanocomposite coatings, where those affected the microstructural, mechanical, tribological, and anti-corrosion characteristics of coatings. The challenges associated with the electroplating of nanocomposite coatings are addressed. The results of this survey indicated that adding graphene into the plating bath led to a finer crystalline size in the composite coating due to increasing the potential development of specific crystalline planes and the number of heterogeneous nucleation sites. This consequently caused an improvement in hardness and in tribological properties of the electrodeposited coating. In graphene reinforced metallic composites, the severe adhesive wear mechanism for pure metallic coatings was replaced by abrasive wear and slight adhesive wear, where the formation of a tribolayer at the contact surface increased the wear resistance and decreased friction coefficient. Furthermore, superhydrophobicity and smaller grain size resulted from embedding graphene in the coating. It also provided a smaller cathode/anode surface ratio against localized corrosion, which has been found to be the main anti-corrosion mechanism for graphene/metal coating. Lastly, the study offers a discussion of the areas of research that need further attention to make these high-performance nanocomposite coatings more suitable for industrial applications.

In this study, we developed a simple high-throughput and cost-effective method for monitoring toxic metal ion in an environmental aqueous sample. Mercury ion determination with Sequential Injection Analysis system (SIAs) coupled with the electrochemical detection on the modified screen-printed carbon working electrode (SPCE) is an alternative green analysis of mercury ion. The gold film was used as the modified material for improved mercury ion analysis in the automated system without memory effect on the electrode. Mercury oxidation signal was found at the potential of 0.7 V in 0.1 M HNO3 and 1.0 M HCl with the concentration low to 0.25 ± 0.18 mg×L-1. Online sample preparation and separation will study in the further experiment.
Effect of A-site modification on structural and microwave dielectric properties of calcium titanate
Authors: RAJPUT Shailendra , KESHRI Sunita
Published: September 2022

This article presents studies on characteristics properties of CaTiO3, Ca0.8Sr0.2TiO3, and Ca0.6La0.8/3TiO3 ceramics. These ceramics were synthesized using the solid-state reaction process. Structural examination revealed that the grown ceramics have an orthorhombic structure with the Pbnm space group. The random distribution of particle size was shown through morphological investigation. Apparent density of developed ceramics was determined using the Archimedes technique and found to be ˂ 90%. The microwave dielectric properties of grown ceramics are compared on the basis of ionic polarizability. It is observed that partial replacement of Ca-ions by Sr-ions provides a high permittivity value (er = 168.93), higher quality factor Q × f = 9,330 GHz), and enhanced positive temperature coefficient of resonant frequency (tf  =  908.17). However, the substitution of Ca-ions by La-ions offers a low permittivity value (113.35), higher quality factor (16,730 GHz), and decreased temperature coefficient of resonant frequency (229.49 ppm/°C). These materials can be used with the ceramics possessing a negative temperature coefficient of resonant frequency to balance its tf- value nearly to zero.

The use of biostimulants, such as salicylic acid (SA) and chitosan, are a sustainable strategy to solve stress problems in plants. Its use has been shown to have synergy with metallic microelements, which are very important for the development of crops under stress situations. An advance in the application of these nutrients is the use of nanoparticles, which emerge as a more precise alternative to achieve optimal plant development. The objective of this study was to evaluate the effect of foliar application of biostimulants, iron (Fe) and zinc (Zn) nanoparticles on growth, nitrogen assimilation, and nutritional content in green bean cv. ‘Strike’. Three treatments were used where complete nutrient solution was applied via foliar, the combination of chitosan (Q) plus SA and nanoparticles of Fe and Zn plus Q and SA. The application of nutrient solution favoured biomass content and carotene content. While the Q+SA treatment increased the nitrate reductase enzymatic activity, the mineral content in the root and the amino acid content, which places it as a viable alternative in situations where the supply of nutrients is limited or the plant cope with stressful situations. For its part, the application of nanoparticles of Fe and Zn plus biostimulants generated an increase in the mineral content of the aerial part, indicating that the application of this type of compound generates a greater mobility of nutrients within the plant.

The objectives of this study were to determine the biological characteristics of diabetic patients who have been diagnosed with COVID-19 and to estimate the risk of death in these patients. The study included 285 COVID-19 individuals whose diagnosis was confirmed by PCR and/or on the basis of typical signs and radiological findings (CT). Patients admitted to the Infectiology Service of Ali Boushaba Public Hospitalier Khenchela, during the year 2020. The data was collected from 1 January to 30 June 2021. The average age of patients diagnosed with COVID-19 in the enumerated population is 62.53 + 16.65 years. A male predominance was noted, with a sex ratio of men to women in the range of 1,29. Old diabetic patients account for 48.80 % of our sample patient. The PCR was positive in 87% of diabetic cases, the oxygen desaturation was 64.7%, and the pulmonary affliction was important or critical in 28.8% and 18.7%, respectively.  A wide range of biological abnormalities was found in diabetic patients, including high CRP in 95.7% of cases, hyperglycemia in 64%, hyperleucocytose in 26.6% of cases, D-dimer elevation in 56% of cases, and hypoprothrombinemia in 21.6% of cases. A high rate of urea and hypo-creatinemia were found in 36.70% and 12% of patients, respectively. As well as high rates of ASAL and ALAT in 28.80% and 26.60% of patients, respectively.  In diabetics a mortality rate of 22.3% was noted. With the exception of glycemia and ALAT, the differences in percentages of these parameters based on the presence of diabetes are statistically insignificant. Furthermore, the diabetic is unrelated to the clinical outcome of the patients. Due to the high number of infections, biological changes, and deaths among diabetics infected with COVID19, it is necessary to consider good care of care of these patients in order to reduce morbidity and mortality rates.
lncRNA MAFG‑AS1 enhances radioresistance of glioblastoma cells via miR‑642a‑5p/Notch1 axis
Authors: Zhang Xi , Li Rui
Published: September 2022

This study was designed to explore the function of lncRNA MAFG‑AS1/miR‑642a‑5p/Notch1 in glioblastoma (GBM) cells under radiation.
GBM cells (M059K and M059J) were transfected or/and irradiated. Western blotting was used to detect Notch1 protein and its downstream Hes1 protein. Cell Counting Kit-8 assay and flow cytometry were applied for viability and apoptosis tests, respectively. Luciferase reporter plasmids and Ago2 antibody were used to verify the predicted binding of miR‑642a‑5p to MAFG‑AS1 or Notch1
mRNA. Notch1 and MAFG‑AS1 were highly expressed and miR‑642a‑5p was lowly expressed in radioresistant M059K cells. Knockdown of Notch1 inhibited radioresistance and promoted apoptosis in M059K cells. MAFG‑AS1 competed with Notch1 mRNA for binding of miR‑642a‑5p and therefore promoted the expression of Notch1. Overexpression of miR‑642a‑5p or silencing of MAFG‑AS1 inhibited the radioresistance of M059K cells. Knockdown of Notch1 or overexpression of miR‑642a‑5p reduced viability and increased apoptosis in irradiated M059J cells overexpressing MAFG‑AS1. MAFG‑AS1 reduces the radiosensitivity of GBM cells via miR‑642a‑5p/Notch1 axis.

Published: September 2022

We aimed to screen the feature genes related to subarachnoid hemorrhage (SAH). The datasets (GSE73378 and GSE36791) were downloaded from National Center for Biotechnology Information database. Limma package in R was used to screen the differentially expressed genes (DEGs). Single sample gene set enrichment analysis algorithm was used to evaluate the type of immune infiltration. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were used to analyze function of DEGs. The support vector machine (SVM) was used to constructed classifier, which was evaluated using receiver operating characteristic curves. The E‑TABM‑421 was used to verify the DEGs related to immunity and the classifier. Seven types of immune cells with significant differences were screened, such as activated CD8 T cell and center memory CD4 T cell. We then obtained 408 DEGs related to immune
cell. Subsequently, 10 overlapped KEGG pathways related to the DEGs were obtained, such as hematopoietic cell lineage, NOD‑like receptor signaling pathway and T cell receptor signaling pathway. Finally, 9 DEGs related to immune cells (CCL5, CD27, CD3D, CREB5, FYN, ITPR3, TAB1, NCR3 and S1PR5) were screened to constructed SVM classifier. The area under the curve was 0.865 in training dataset and the AUC was 0.75 in the validation set. A SVM classifier based on the 9 DEGs (CCL5, CD27, CD3D, CREB5, FYN, ITPR3, TAB1, NCR3 and S1PR5) related to immune cells might effectively identify SAH patients or healthy people.
Bone marrow stromal cells attenuate oxygen and glucose deprivation followed by re‑oxygenation‑induced brain microvascular endothelial cell injury

Published: September 2022

Ischemic stroke is a severe threat to the health of older individuals. Bone marrow mesenchymal stem cells (BMSCs) have been implicated in ischemic stroke. Urokinase‑type plasminogen activator (uPA) and its specific receptor (uPAR) are associated with the pathological process of ischemic stroke. However, the relationship between BMSCs and uPA/uPAR in ischemic stroke remains unclear. For simulating the occurrence of an ischemic stroke in vitro, human cerebral microvascular endothelial cells (HBMECs) were subjected to oxygen and glucose deprivation followed by re‑oxygenation (OGD/R) and were then cocultured with BMSCs. 3,4,5‑dimethylthiazol‑2,5‑diphenyltetrazolium bromide and bromodeoxyuridine staining were used for measuring cell viability and proliferation. Flow cytometry was performed for assessing cell apoptosis. Endothelial cell tube formation was determined using angiogenesis assays. Alterations in the protein and gene expression in HBMECs were evaluated using western blot analysis and quantitative reverse transcription‑polymerase chain reaction, respectively. OGD/R considerably inhibited the viability and proliferation of HBMECs by inducing apoptosis, which was reversed by BMSCs. Consistently, OGD/R‑induced inhibition of angiogenesis was attenuated by BMSCs. In addition, BMSCs could protect HBMECs against OGD/R‑induced injury by positively regulating the uPA/uPAR/stromal cell‑derived factor‑1α (SDF‑1α)/C‑X‑C chemokine receptor type 4 (CXCR4) pathway, and uPA/uPAR could mediate the SDF‑1α/CXCR4 pathway in OGD/R‑treated HBMECs. Therefore, this study provides novel strategies to investigate the specific role of BMSCs in ameliorating OGD/R‑induced vascular endothelial cell injury.

Published: September 2022

Antimicrobial resistance (AMR) is a growing global epidemic due to the improper overuse of antimicrobials in the agriculture, veterinary, and medical sectors. Antimicrobial-resistant genes (ARGs) spread primarily through the environment, which is becoming a growing concern among researchers and stakeholders. Antibiotic-resistant bacteria and their ARGs are spread by various factors, such as the use of antimicrobial drugs in health care, agriculture and livestock, and the environment, as well as the release of antibiotic residue. Through various routes and hotspots such as hospital wastewater, agricultural waste, and wastewater treatment plants, resistant microorganisms, and their resistance genes enter the soil, air, water, and sediments. It is important to identify high-risk environments that cause the evolution of resistance and its spread around the world if global mitigation strategies are to be effective. As a result, infection control, sanitation, access to clean water, antimicrobials, diagnostics, travel, and migration are all factors impacting AMR transmission. Through various mechanisms, this review discusses AMR as a global concern and how environmental factors may contribute to the spread of antibiotic-resistant bacteria.

В процессе научно-исследовательской работы изучены энокарпологические и энохимические показатели гроздей и ягод виноградных кустов в популяциях местных технических сортов Мадраса, Баянширей, Хиндогны, Ширваншахы и интродуцированного сорта Молдова универсального направления использования, которые являются ценным сырьем, в значительной степени составляющим материальную базу для производства национальных марок вин Азербайджана; по этим показателям определены степень разнообразия и изменчивости виноградного растения. Установлено, что кусты винограда разных сортов, в том числе кусты в популяции одного сорта (внутрисортовые), достоверно отличаются друг от друга по увологическим показателям. К этим показателям относятся размер грозди и ягод, масса грозди, количество ягод в грозди, масса 100 ягод, количество механических элементов грозди и их соотношение, энохимический состав сока и т.д. В результате биометрического и математико-статистического сравнительного анализа и группировки этих показателей было отобрано 5 первичных маточных кустов (протоклонов) для сортов Хиндогны и Мадраса, 4 протоклона для сортов Баянширей и Молдова, 2 протоклона для сорта Ширваншахы. Отобранные протоклоны отличаются от родительских кустов по одному или нескольким признакам и даже значительно превосходят их по многим признакам. Одним из признаков, повышающих технологическую пригодность технических сортов винограда, является выход сока. У родительских кустов этот показатель колеблется от 43,5 (Хиндогни) до 76,8 % (Молдова), а у кустов-клонов изменяется от 45,8 (клон Ш-20-2 сорта Мадраса) до 75,0 % (клон Аб-19-14 сорта Хиндогны, клон Гя-10-52 сорта Баянширей, клон Аб-20-м7 сорта Молдова). Количество сухого вещества у сортов Хиндогны, Мадраса, Молдова, Баянширей, Ширваншахы и их клоновых форм колеблется от 17,7 до 26,5 по шкале Брикса, что считается типичным для технических сортов винограда.

In 2016, China put forward the topic of green finance and inclusive finance at the G20 Summit in Hangzhou. Since then, more and more scholars in China have paid attention to the possibility and influence of the integrated development of green finance and inclusive finance. In recent years, China has gradually established a domestic green financial market system through a series of measures such as issuing green financial standards, disclosure requirements and encouraging green financial product innovation. According to data from the National Statistical Bulletin, by the end of 2021, the loan balance of major rural financial institutions (rural credit cooperatives, rural cooperative banks, rural commercial banks) was 2.42496 trillion yuan, an increase of 2.6607 billion yuan compared with the beginning of the year. From the perspective of Liaoning Province, at the end of 2020, the balance of loans in domestic and foreign currencies of banking financial institutions in Liaoning was 520.94 billion yuan, an increase of 262.68-billion-yuan year-on-year, an increase of 5.3% year-on-year. The growth rate slowed down, with a decrease of 4.9 percentage points compared with the previous year.

Ubuntu translanguaging as a systematic approach to language teaching in multilingual classrooms in South Africa
Authors: Sefotho Malephole Philomena M.
Published: September 2022

The Language in Education Policy recognises the linguistically super-diverse nature of learners in South African schools and provides allowance to use more than one language in teaching and learning within the framework of promoting multilingualism. This policy adopted an additive approach and encouraged school governing bodies to establish how they will promote multilingualism through the use of more than one language. However, it seems there is lack of systematic approaches on how schools should promote multilingualism. This study, therefore, looked at how Ubuntu translanguaging can be applied as a systematic approach in schools to promote multilingualism. This small-scale exploratory qualitative study made use of semi-structured interviews and classroom observations to explore how teachers incorporated and understood the Policy in promoting multilingualism. It was found that teachers used more than one language to enhance learning, though they believed this was not allowed and that they were required/expected to use only one language for learning and teaching at a time. The study concludes that there is a misunderstanding or misinterpretation of the Policy and recommends that the policy be unpacked and clarified for teachers. It further recommends the Ubuntu translanguaging pedagogy to be accepted as a systematic approach to promote multilingualism.

Abstract

Reading the context – the applicability of neohistoricism to Goran Stefanovski`s plays

Goran Stefanovski's plays are subject to the neo-historical method because it is directly related to both the social and geo-political context. All the plays of his opus can be treated according to the neo-historical method and at the same time they are an example of how a dramatic opus can be analyzed according to the contemporary and current theory. Goran Stefanovski's plays, precisely because of the author's immanent urge, are closely related to the context, the cultural matrix and the synchronic model (offered by Stephen Greenblatt, the founder of the method) is imposed as a logical tool in the process of their interpretation, periodization and even projection. This paper is designed to show the applicability of the method in Goran Stefanovski's drama, through examples from most of his plays.

The Philippines is a “hotspot” for sea cucumbers in Asia, where decades of lack of management led to declining fisheries and biodiversity. Sea cucumbers have been widely gathered in Mindanao; however, only a few studies provide updates on sea cucumber diversity and abundance. To supplement this scant information, a survey was conducted in the eight chosen sites of the five major sea cucumber fishing grounds aimed at assessing the status of sea cucumber diversity, density, and average sizes. Line-transect surveys carried out from May–August 2021 found 22 sea cucumber species across eight sites – including two high-value species, Actinopyga lecanora, and Holothuria scabra. The most common species are Actinopyga echinites and Stichopus horrens considered of medium-value and found in all surveyed sites. H. scabra and A. echinites are listed in the International Union for Conservation of Nature (IUCN) red list as “endangered” and “vulnerable,” respectively, whereas the remaining sea cucumbers are either data deficient or least concerned. Tambunan MPA (marine protected area) in Tabina had the highest sea cucumber density (3,560 ind. ha–1) during daytime sampling, whereas Solar in Olutanga (3,220 ind. ha–1) during nighttime. High relative abundance of low to no commercial value holothurians were recorded during daytime and medium-value species during nighttime. The low-value Holothuria atra is the most abundant (27.2%) sea cucumber. Shannon diversity index revealed low diversity during daytime (0.13–1.43), whereas Bacayawan in Dimataling and Passig Islet in Sta. Cruz had a Shannon diversity value of > 1.5 in the nighttime. Average sizes of sea cucumbers in the surveyed sites are generally small (< 20 cm), except for a few species. The results of the study serve as baseline information for the formulation and implementation of site-specific local policies and management programs for the sustainability and conservation of sea cucumber stocks.
Ethnobotany of Medicinal Seaweeds of Ilocos Norte, Philippines
Authors: Dumilag Richard , Javier Raymundo
Published: September 2022

The Ilocano people of Ilocos Norte in the Philippines have high regard for seaweed use. The traditional seaweed medicines used by them are old and time-tested, albeit little explored. This study examines the selection of seaweeds associated with a defined folk knowledge and their source availability in Ilocos Norte. Thirty-four (34) seaweed species were traditionally perceived as medicinal for eight types of emic indications, almost 80% of which were edible. Three major groups, i.e. rhodophytes (16 spp.), ochrophytes (7 spp.), and chlorophytes (11 spp.), of 12 families and 20 genera constituted the list. Most species were used for digestive, pulmonary, and glandular-related complaints. The Ilocano residing Pagudpud and Burgos were the most familiar in terms of the number of used species. Caulerpa racemosa (ar-arusip) was the most familiar seaweed used as a cough or asthma reliever. Caulerpa racemosa, Hydroclathrus clathratus, and Gracilaria edulis had the highest use value, whereas Codium intricatum, Gelidiella acerosa, and C. racemosa had the highest fidelity level scores. The distribution of taxa in dry and wet seasons markedly varied per site. Gelidiella acerosa was the only species growing on all sites year-round. Correspondence between folk use and phytochemical activity was inferred in nearly all listed species. The information presented here will allow continued validations and tests of folk medicinal seaweeds for new drugs and may bring additional armamentarium to the Philippine pharmacopeia.

Published: September 2022

Unemployment has been a long-standing problem in many countries, including the Philippines, and the recent pandemic even worsened the economic conditions of Filipinos with a large part of the population losing their jobs. One way to create more platforms that will enable the employability of the population is through the technical and vocational education and training (TVET) program, whose goal is to produce middle- and high-skilled graduates ready to take on the demands of the rapidly changing economy. With the current gender gap in terms of employment, this study focuses on the employment status of female graduates of TVET and the possible factors that influence the employment of Filipino female TVET graduates were determined. The survey data collected by the Technical Education and Skills Development Authority (TESDA) in 2018 for their employability study of 2017 women TVET graduates was utilized in this study. Binary Firth logistic regression models were fitted on subpopulations of TVET female graduates who were employed before and after training. Results have shown a significant increase in the proportion of employed women after graduation, which was indicated in the estimates before and after the training. Among the unemployed Filipino female before the training, more than half of them (52%) were employed after the training. Age, education, region, and reasons for taking up a program showed to be determinants of the employability of female TVET graduates. The factors that hinder women from entering employment despite their TVET training is the primacy of their household and family duties. Their choice or nature of programs shows that women take stereotypical roles associated with women, an issue that is still present today because of prevailing traditional gender norms. With the huge decline in economic activities brought by the pandemic, the results of this study will be particularly important in creating more and better employment opportunities for Filipino women.
Physiological Responses, Growth, and Heavy Metal Accumulation of Citronella (Cymbopogon nardus Rendle. ) in Cu-Ni Mine Tailings as Affected by Soil Amendments
Authors: Ultra Venecio , Ngwako Kutlo Martin , Eliason Peter
Published: September 2022

This study aimed to contribute to the rehabilitation and remediation of mine tailings and heavy metal (HM) contaminated environments through phytostabilization using plants with added economic benefits such as citronella (Cymbopogon nardus Rendle.). A greenhouse pot experiment of citronella was evaluated in Cu-Ni mine tailings by monitoring its growth rate, physiological responses, and HM accumulation as affected by the application of four different soil amendments under greenhouse conditions. The treatments include T1 (control) as tailings without amendments, T2 as tailings + 10% cow manure (v/v), T3 as tailings + 10% compost (mixture of organic farm waste and manure, v/v), T4 as tailings + lime at 5 tons ha–1, T5 as tailings + lime (2x) at 10 tons ha–1, and T6 as tailings + 10% fly ash (FA) by volume. After 24 wk, soil amendments enhanced dry matter yield and increased chlorophyll content, leading to higher photosynthetic rate and rubisco activity in the leaves of citronella. These amendments reduced the availability of HM in tailings and consequently reduced its translocation to above- ground parts and the concentration in shoots. Cow manure, FA, and compost increased the total N, available P, and exchangeable K in tailings. Applications of FA, compost, lime, and cow manure significantly enhanced the survival and growth of citronella in tailings and thereby increased the potential of citronella as phytostabilization agents of Cu-Ni tailings. The high dry matter yield of citronella will produce a high volume of essential oils as an additional benefit.

Proses membimbing siswa di sekolah yang dilakukan oleh guru tidak saja secara akademik tetapi juga membimbing siswa untuk memiliki sikap dan karakter yang baik. Oleh karena itu guru perlu tahu metode yang tepat untuk proses pembimbangan kepada siswa. Teori Skinner adalah salah satu motode untuk menolong guru dalam membimbing siswa karena dalam teori Skinner terdapat penguatan (reinforcement), hukuman (punishment), pembentukan (shaping).

Tetapi terkadang masih banyak guru yang hanya memberikan hukuman saja kepada siswa yang bermasalah tanpa memberikan penguatan dan pembentukan. Tujuan penelitian ini adalah untuk mengetahui arti dari teori B.F. Skinner  supaya guru-guru di sekolah dapat menerapkan teori ini untuk membimbing siswa di sekolah. Untuk mencapai tujuan tersebut, penulis menggunakan metode penelitian dekriptif, yang ditindaklanjuti dengan penelitian lapangan dengan cara mengumpulkan data dan melakukan wawancara. Berdasarkan hasil penelitian penulis, masih banyak guru-guru yang belum memahami teori Skinner ini dan ada juga guru yang masih beranggapan bahwa memberikan hukuman itu wajib sedangkan penguatan dan pembentukan tidak perlu.

Perkembangan sosial emosioal merupakan aspek perkembangan yang menunjukkan kemampuan anak untuk berinteraksi dan bersosialisasi dengan baik dan mampu mengerti aturan-aturan yang berlaku dilingkungan sekitar dengan kemampuan dalam mengungkapan perasaan. Perilaku dan sikap sosial emosional anak sangat dipengaruhi oleh lingkungan. Pembentukan dan peningkatan sosial emosial anak merupakan tugas dan tanggung jawab orang tua. Namun pada kenyataannya masih ditemukan orang tua yang kurang berperan atau bahkan tidak berperan dalam perkembangan dan peningkatan sosiol emosional pada anak, sehingga berakibat anak menjadi pemurung, agresif, kasar, tidak mampu mengontrol emosi, sulit mengungkapkan keinginan, sulit berinteraksi dan bersosialisasi, dan bertampak terhadap perilaku anak.

Dalam penelitian ini, penulis menggunakan metode deskriptif, yang ditindaklanjuti dengan penelitian literatur. Metode deskriptif adalah suatu metode dalam meneliti status sekelompok manusia, suatu objek, suatu kondisi, suatu sistem pemikiran atau pun suatu kelas peristiwa pada masa sekarang, dengan tujuan untuk mendapatkan gambaran yang benar dari suatu objek.

Berdasarkan dari pemaparan hasil penelitian yang ditemukan dari berbagai sumber, menjelaskan bahwa: Peran orang tua dalam peningkatan sosial emosional anak usia 4-6 tahun sebagai pendidik pertama dan merupakan cerminan anak dalam segala aspek baik perilaku, emosional dan cara bersosialisasi masih ditemukan orang tua yang kurang atau bahkan yang tidak berperan dalam peningkatan sosial emosional anak.
Pola Penginjilan Lintas Budaya oleh Tenaga Utusan Gereja (TUG) berdasarkan Kisah Para Rasul 8:26-40 di Gereja POUK Ichtus Bumi Dirgantara Permai Bekasi

The church exists because there is a mission. Therefore, the living church should remain focused on the mission of evangelism. Evangelism is a top priority that must be done by the church in a wide dimension, to the ends of the earth. In reality, there are many churches that are not active in the worldwide evangelistic missionary movement. Why? Is it because the church doesn't want to be involved in the mission or because the church doesn't know about missions? Evangelism must be an ongoing movement. Evangelism is carried out cross-culturally both within the country itself and abroad where neglected tribes (STA) are still found. In an effort to maximize cross-cultural evangelism, the church needs to hold congregational member development continuously. Coaching is intended to change and equalize perspectives or perspectives on cross-cultural evangelism missions. Based on observations and interviews conducted with several church missionaries (TUG) of the POUK Ichtus Bumi Dirgantara Permai Bekasi, it was found that the obstacles to cross-cultural evangelism were not primarily the ethnic groups to be served, but the readiness of the envoys who would serve cross-culturally. These obstacles are mainly related to language, culture and life values ​​that should be studied carefully before serving in these neglected tribes. By referring to the Bible, Acts 8:26-40, the principles and patterns of cross-cultural evangelism are found by studying the profile of Philip who preached the gospel across cultures.

Published: September 2022

O fatiamento de rede é fundamental para suportar a coexistência de requisitos divergentes sobre o mesmo recurso de rede. O fatiamento de rede foi amplamente explorado no processo de especificação e padronização da arquiteturas de redes móveis de quinta geração (5G). Por isso, as propostas da literatura concentram-se predominantemente em prover fatiamento de rede nesse segmento de rede. As abordagens que propuseram realizar o fatiamento de rede para além de redes móveis mostraram-se funcionalmente incapazes de prover fatiamento de rede entre múltiplos Sistemas Autônomos (SAs). Nesse sentido, essa pesquisa buscou de construir um método de fatiamento de rede entre múltiplos SAs, baseando-se nos algoritmos de roteamento da Internet. Experimentos realizados em cenário significativos constataram a aplicabilidade, pertinência e desempenho do método proposto em contraste com os tradicionais do estado da arte.
In search of efficient scheduling heuristics from simulations and Machine Learning
Authors: Rosa Lucas , Goldman Alfredo
Published: September 2022

High Performance Computing (HPC) systems are used to solve a number of complex issues in different fields of knowledge. However, these platforms have been rapidly evolving in size and complexity; and ensuring efficiency in managing applications (jobs) has become a challenge. Typically, this management involves scheduling heuristics that consist of functions to order the jobs. In this work we evaluate the limits of regression methods for creating scheduling heuristics. Our results show that the simplest heuristic led to the most efficient scheduling, while the more complex heuristics showed instabilities due to multicollinearity.

Science Mapping and Science Maps
Authors: Petrovich Eugenio
Published: September 2022

Science maps are visual representations of the structure and dynamics of scholarly knowl­edge. They aim to show how fields, disciplines, journals, scientists, publications, and scientific terms relate to each other. Science mapping is the body of methods and techniques that have been developed for generating science maps. This entry is an introduction to science maps and science mapping. It focuses on the conceptual, theoretical, and methodological issues of science mapping, rather than on the mathematical formulation of science mapping techniques. After a brief history of science mapping, we describe the general procedure for building a science map, presenting the data sources and the methods to select, clean, and pre-process the data. Next, we examine in detail how the most common types of science maps, namely the citation-based and the term-based, are generated. Both are based on networks: the former on the network of publications connected by citations, the latter on the network of terms co-occurring in publications. We review the rationale behind these mapping approaches, as well as the techniques and methods to build the maps (from the extraction of the network to the visualization and enrichment of the map). We also present less-common types of science maps, including co-authorship networks, interlocking editorship networks, maps based on patents’ data, and geographic maps of science. Moreover, we consider how time can be represented in science maps to investigate the dynamics of science. We also discuss some epistemological and sociological topics that can help in the interpretation, contextualization, and assessment of science maps. Then, we present some possible applications of science maps in science policy. In the conclusion, we point out why science mapping may be interesting for all the branches of meta-science, from knowl­edge organization to epistemology.
Die Bildung der Seele
Authors: Ziegler Ursula
Published: September 2022

Plato's concept of education raises the question of the conditions under which the epistemic quest and a change in the attitude of the soul actually correlate. The Platonic motifs of self-care and a good life, soul therapy and shame lead, as this study shows, to a self-reflective movement of knowledge, which has an orienting effect in view of the good and a mediating and ordering effect regarding the soul-body relationship. This work contours the dynamics of learning processes on specific, and figurative, forms of representation and on transitions of knowledge. Plato's anchoring of his educational concept in a philosophical anthropology and his transformation of rhetoric and poetics become manifest through the figure of Eros in the ‘Phaedrus’.
Konkrete Gerechtigkeit
Authors: Mahlmann Matthias
Published: September 2022

Das Buch gibt einen Überblick über Recht und Rechtswissenschaft der Gegenwart für Jurastudierende und für Interessierte aus anderen Disziplinen, die erfahren möchten, was Recht eigentlich ausmacht. Ausgehend von dem Befund, dass modernes Recht nur in internationalen Zusammenhängen und interdisziplinär verstanden und erschlossen werden kann, wirkt das Werk der Gefahr entgegen, sich in den Details spezieller Rechtsgebiete zu verlieren, und zeigt den berühmten „roten Faden“ auf. Damit ist die Darstellung des Rechts in seiner Struktur anschlussfähig für die Nachbarwissenschaften. Der Band gibt Orientierung und schafft Selbstvergewisserung, wenn über Recht und Rechtsystem als Teil der Gesellschaft in seinen sozialen, politischen, wirtschaftlichen und religiösen Dimensionen reflektiert werden soll.
Interfacial Synthesis of 2D COF Thin Films
Authors: Zhang Tao , Zhao Yuxiang
Published: September 2022

Two-dimensional covalent organic frameworks (2D COFs) are emerging crystalline 2D organic material comprising planar and covalent networks with long-ranging structural order. Benefiting from their intrinsic porosity, crystallinity, and electrical properties, 2D COFs have displayed great potential for separation, energy conversion, and electronic fields. For the most of these applications, large-area and highly-ordered 2D COFs thin films are required. As such, considerable efforts have been devoted to exploring the fabrication of 2D COF thin films with controllable architectures and properties. In this chapter, we aim to provide the recent advances in the fabrication of 2D COF thin films and highlight the advantages and limitations of different methods focusing on chemical bonding, morphology, and crystal structure.
