Published: November 2021

Çok değişkenli ikiden fazla grup ortalama vektörünün karşılaştırılması genellikle Çok Değişkenli Varyans Analizi (MANOVA) problemi olarak bilinmektedir. Ancak MANOVA problemlerinin çözümü için kullanılan klasik test istatistikleri, varsayım ihlallerinden oldukça fazla etkilenmektedir. Ayrıca bağımlı değişken sayısının gözlem sayısından daha büyük olduğu durumlarda çok değişkenli test istatistikleri yetersiz kalmaktadır. Bu çalışmanın amacı, yüksek boyutlu Behrens-Fisher problemlerinde ortalama vektörlerin eşit olup olmadığını belirlemek için önerilen bazı test istatistiklerini karşılaştırmaktır. Bu amaçla varyans-kovaryans matrislerinin heterojen olduğu durumlarda dört farklı test istatistiği için bir simülasyon analizi gerçekleştirilmiştir. Çalışmada üç farklı varyans-kovaryans modeli kullanılmıştır. Ayrıca bağımlı değişken sayısı ve gözlem sayısı için farklı deneysel koşullar dikkate alınmıştır. Çalışmanın sonuçları, test istatistiklerinin performanslarının genel olarak karşılaştırılabilir olduğunu göstermiştir. Ancak deneysel koşullara göre test istatistiklerinin performansının değiştiği gözlemlenmiştir.

In this study, thermal (2.53*10-8 MeV) and fast (2 MeV) neutron total macroscopic cross-sections of paraffin, polycarbonate, and polyester matrix polymers doped with B4C, B2O3, Sm2O3, and Gd2O3 (at weight percentages of 5%, 10%, 15%, 20%, and 25%) were computed by using Monte Carlo simulations. Additionally, the macroscopic effective removal cross-section ) of fast neutrons was theoretically computed based on the mass removal cross-section values ) for various elements in polymers and additives. The obtained results show that the highest thermal neutron total macroscopic cross-section was obtained in polycarbonate doped with Gd2O3, and the highest fast neutron total macroscopic cross-section was observed in paraffin doped with Sm2O3. Besides, the paraffin provided the highest fast neutron total macroscopic cross-section for all additives. The results of this study provide a good understanding of shielding properties of paraffin, polycarbonate, and polyester matrix polymers doped with B4C, B2O3, Sm2O3, and Gd2O3 against thermal and fast neutrons.

Interdisciplinary Synthesis in Economics
Authors:   Institute of Economics of the RAS, Provolovich T.O.
Published: November 2021

The paper aims to identify the factors that influence the methods and outcomes of interdisciplinary and multidisciplinary synthesis in economics, in particular with natural science, social studies and humanities. Our analysis focused on neuroeconomics resulting from an interdisciplinary synthesis of economics and neuroscience. We also considered the multidisciplinary economic socio-cognitive-neurobiological synthesis of Peter C. Whybrow and Matthew D. Lieberman. Third, we analyzed the multidisciplinary synthesis of psychology, economics and sociology by Y. I. Alexandrov and S. G. Kirdina-Chandler. We compared these cases of modern interdisciplinary synthesis and showed that the experimental ideal of the natural sciences which neuroeconomics is oriented at creates methodological constraints for the research of socio-economic processes, aspects of human society and culture. In other words, these processes and phenomena are reduced to biological or physical ones. Thus, neuroeconomics can serve as an example of ‘unequal interdisciplinary relation’. The multidisciplinary synthesis of Wybrow and Lieberman is more successful. It provides a comprehensive description of both the economic agent and the social reality in which it resides and it explains economic interactions within a broader perspective. However, this synthesis is still at the initial stage, since most of the statements are hypothetical and require additional experimental verification. We believe that the multidisciplinary synthesis of Alexandrov and Kirdina-Chandler (Alexandrov, Kirdina, 2012) is the most promising for economic research. We distinguish two main factors for the success of interdisciplinary and multidisciplinary synthesis in economics: either none of the sciences involved in the synthesis dominates or the synthesis is based on the general picture of the world, including objects and methods from different sciences and relies on a single meta-methodology or paradigm methodology.
Gender and feminist considerations in Artificial Intelligence from a developing-world perspective, with India as a case study
Authors: CHOUDHURY SANGHAMITRA , Kumar Shailendra
Published: November 2021

The relationship between women, technology manifestation, and likely prospects in the developing world is discussed in this manuscript. Using India as a case study, the paper goes on to discuss how ontology and epistemology views utilised in AI (Artificial Intelligence) and robotics will affect women's prospects in developing countries. Women in developing countries, notably in South Asia, are perceived as doing domestic work and are underrepresented in high-level professions. They are disproportionately underemployed and face prejudice in the workplace. The purpose of this study is to determine if the introduction of AI would exacerbate the already precarious situation of women in the developing world or if it would serve as a liberating force. While studies on the impact of AI on women have been undertaken in developed countries, there has been less research in developing countries. This manuscript attempts to fill that need.
Mengelola Sumber Daya Manusia
Authors: Jannah Miftahul
Published: November 2021

Sumber daya manusia sebagai salah satu sumber daya yang ada dalam organisasi memegang peranan yang penting dalam keberhasilan pencapaian tujuan organisasi. Sumber daya manusia menggunakan sumber daya-sumber daya lain yang dimiliki oleh organisasi dalam rangka mencapai tujuan. Mesin-mesin berteknologi canggih sekalipun tidak akan ada artinya, jika sumber daya manusia yang menjalankannya tidak berkualifikasi untuk mengerjakannya. Demikian juga dengan sumber daya informasi. Sebaik dan selengkap apapun informasi yang diterima oleh organisasi, tidak akan berarti apa-apa, jika kualitas sumber daya manusia yang ada tidak mampu menterjemahkannya menjadi informasi yang berguna bagi perkembangan dan kemajuan organisasi. Sumber daya manusia adalah penduduk yang siap, mau dan mampu memberikan sumbangan terhadap usaha mencapai tujuan organisasional. Dalam ilmu kependudukan, konsep sumber daya manusia ini dapat disejajarkan dengan konsep tenaga kerja (manpower) yang meliputi angkatan kerja (labor force) dan bukan angkatan kerja. Angkatan kerja yang bekerja disebut juga dengan pekerja. (Ndraha, 1999).
Coproduce conservation technology with conservation decisionmakers and practitioners to increase its impact
Authors: Malcom Jacob , Evans Michael John , Norriss Jessica , Foster Victoria , Moskwik Matthew
Published: November 2021

Addressing the biodiversity crisis will mean developing and adopting new resources and methods that effectively improve public conservation efforts. Technologies have a long track record of increasing the efficiency of carrying out time-consuming tasks or even making new feats possible, and if applied thoughtfully, can serve as a key means of strengthening conservation outcomes. Yet technology development sometimes proceeds without clear mechanisms for application and scaling, or key adopters like government agencies are not able to use the technologies. To overcome these discrepancies, we recommend the use of a coproduction model of conservation technology development that starts from detailed knowledge of conservation laws, regulations, and policies; identifies choke points in those processes amenable to technological solutions; and then develops those solutions while integrating existing users and needs. To illustrate the model, we describe three tools recently developed to help improve the efficiency and effectiveness of implementing the U.S. Endangered Species Act. We also highlight several outstanding questions and challenges that the broad conservation technology and policy communities may help address.
Process Modeling of Thermoset Composites used for Wind Blade Manufacturing
Authors: Shah Sagar P. , Patil Sagar U. , Hansen Christopher J. , Odegard Gregory M. , Maiaru Marianna
Published: November 2021

A computational process modeling framework, informed by accurate material characterization, is presented for virtual manufacturing of wind energy thermoset composites. Process modeling simulations of composite microstructures are carried out to predict in-situ matrix property evolution and performance-altering residual stress generation. To achieve this, comprehensive material characterization effort is carried out. A novel material property dataset for a widely-used wind energy thermoset system is generated as a function of the temperature and curing. Informed by these material properties, the ability of the process model to reliably estimate manufacturing-induced residual stresses is highlighted. For a prescribed cure cycle, in-situ elastic modulus evolution, chemical and thermal strains, and random fiber distribution are shown to significantly influence residual stress generation. The results also show that a full process modeling analysis that includes the complete cure cycle (instead of the standard approach of just considering post-processing cool-down) is necessary to accurately predict manufacturing-induced residual stresses.
Costly habitual avoidance is reduced by concurrent goal-directed approach in a modified devaluation paradigm
Authors: Glück Valentina , Zwosta Katharina , Wolfensteller Uta , Ruge Hannes , Pittig Andre
Published: November 2021

Avoidance habits potentially contribute to maintaining maladaptive, costly avoidance behaviors that persist in the absence of threat. However, experimental evidence about costly habitual avoidance is scarce. In two experiments, we tested whether extensively trained avoidance impairs the subsequent goal-directed approach of rewards. Healthy participants were extensively trained to avoid an aversive outcome by performing simple responses to distinct full-screen color stimuli. After the subsequent devaluation of the aversive outcome, participants received monetary rewards for correct responses to neutral object pictures, which were presented on top of the same full-screen colors. These approach responses were either compatible or incompatible with habitual avoidance responses. Notably, the full-screen colors were not relevant to inform approach responses. In Experiment 1, participants were not instructed about post-devaluation stimulus-response-reward contingencies. Accuracy was lower in habit-incompatible than in habit-compatible trials, indicating costly avoidance, whereas reaction times did not differ. In Experiment 2, contingencies were explicitly instructed. Accuracy differences disappeared, but reaction times were slower in habit-incompatible than in habit-compatible trials, indicating low-cost habitual avoidance tendencies. These findings suggest a small but consistent impact of habitual avoidance tendencies on subsequent goal-directed approach. Costly habitual responding could, however, be inhibited when competing goal-directed approach was easily realizable.
My mind is not the universe – where/what is the universe?
Authors: Yu Xiaoyang
Published: November 2021

In order to describe my findings/conclusions systematically, a new semantic system (i.e., a new language) has to be intentionally defined by the present article. Humans are limited in what they know by the technical limitation of their cortical language network. The conventionally-called “physical/objective reality” around my conventionally-called “physical/objective body” is actually a geometric mathematical model (being generated/mathematically-modeled by my brain) – it's actually a subset/component/part/element of my brain’s mind/consciousness. A reality is a situation model (SM). Our universe is an autonomous objective parallel computing automaton (aka state machine) which evolves by itself automatically/unintentionally – wave-particle duality and Heisenberg’s uncertainty principle can be explained under this SM of my brain. Each elementary particle (as a building block of our universe) is an autonomous mathematical entity itself (i.e., a thing in itself). Our universe has the same nature as a Game of Life system – both are autonomous objective parallel-computing automata. If we are happy to accept randomness, then it is obviously possible that all other worlds in the many-worlds interpretation do not exist objectively. The conventionally-called “space” does not exist objectively. “Time” and “matter” are not physical. Consciousness is the subjective-form (aka quale) of the mathematical models (of the objective universe) which are intracorporeally/subjectively used by the control logic of a Turing machine’s program directly-fatedly. A Turing machine’s consciousness or deliberate decisions/choices should not be able to actually/objectively change/control/drive the (autonomous or directly-fated) worldline of any elementary particle within this world. Besides the Schrodinger equation (or another mathematical equation/function which is yet to be discovered) which is a valid/correct/factual causality of our universe, every other causality (of our universe) is either invalid/incorrect/counterfactual or can be proved by deductive inference based on the Schrodinger equation (or the aforementioned yet-to-be-discovered mathematical equation/function) only. Consciousness plays no causal role (“epiphenomenalism”), or in other words, any cognitive/behavioural activity can in principle be carried out without consciousness (“conscious inessentialism”). If the “loop quantum gravity” theory is correct, then time/space does not actually/objectively exist in the objective-evolution of the objective universe, or in other words, we should not use the subjective/mental concept of “time”, “state” or “space” to describe/imagine the objective-evolution of our universe.

Introduction: Stunting is the most prevalent form of child malnutrition worldwide, and is the best overall indicator of growth. This study aimed to determine the relationship between maternal characteristics and nutritional status of children aged 0-23 months based on their length/height-for-age. Method: The study used data from the 2015 Updating Survey conducted by the Philippines’ Food and Nutrition Research Institute – Department of Science and Technology. It employed a stratified multi-stage sampling technique covering all regions in the Philippines. Mothers (n=5,254) of sampled children 0-23 months were the respondents of the Maternal Health and Nutrition survey. The length-for-age z-scores (LAZ) of children and maternal characteristics were analysed. Rao-Scott Chi-square test was used for association analysis. Logistic regression was performed for model fitting. Results: A quarter (25.2%) of children aged 0-23 months in the Philippines at the time of the survey were stunted, with the highest prevalence (36.2%) observed among 12-23 months. Children being stunted or normal in height was associated with prenatal services, maternal nutritional status, education, and duration of lactation. Maternal education (OR: 0.39; p=0.012), age-appropriate breastfeeding (OR: 0.63; p=0.042), and prenatal services like tetanus toxoid vaccination (OR: 0.67; p=0.011) and ultrasound (OR: 0.71; p=0.025) lowered the likelihood of a child being stunted. Conclusion: It is recommended to strengthen and intensify service delivery among pregnant and lactating women because of the implication of maternal factors to the length-for-age status of children 0-23 months.

Published: November 2021

Background and Aims: Two dimensional transthoracic echocardiography (2DE) is widely used for detecting congenital heart disease and is possible to obtain precise measurement of Patent ductus arteriosus (PDA) for device selection required for transcatheter closure. Primary aim of the study is to determine whether echocardiographic assessment alone can be used for selection of device for transcatheter closure of PDA.

Methods: Children with PDA and planned for transcatheter intervention were included in this cross-sectional study of one year. PDA was assessed with 2DE and prediction of device size was made.

Results: The results were obtained from 107 children. The median age and weight at intervention were 3.8 years (ranging from 6 months to14 years) and 12 kg (ranging from 3.5 to 60 kg). Type A (Conical) PDA was the commonest PDA morphology accounting for 87.8% and 85% in 2DE and angiography respectively. There was no difference (p < 0.05) in the narrowest diameter at pulmonary end measured by 2DE and angiography, however ampulla diameter and ductal length were statistically different (p = 0.95). The predicted size of device by 2DE was discordant (p < 0.05) to the actual device used in a total study population, however when patients with severe pulmonary hypertension, non-type A and larger PDA (narrowest diameter > 6mm) were excluded, the predicted size of device by 2DE was statistically concordant (p = 0.1) to the actual device used in 89 (83%) patients.

Conclusion: Two dimensional Transthoracic echocardiography alone may be helpful in choosing the device during transcatheter closure of PDA in selective group of patients.

Extended tight-binding quantum chemical method (GFN2-xTB) was performed to investigate the adsorption of 2,4-dichlorophenoxylacetic acid (2,4-D) on activated carbon (AC) and AC modified by Fe or Ag (AC-M). Electronic properties of the studied systems were estimated via vertical ionisation potential, vertical electron affinity, and global electrophilicity index. Adsorption energy, population analysis, and geometrical parameters were calculated to clarify the adsorption ability of AC and AC-M. The results indicated that the introduction of metal atoms to AC substantially enhanced the adsorption ability for 2,4-D. The adsorption mechanism changed from physical adsorption (on AC) to chemisorption (on AC-M). The influence of different solvents (water, methanol, and acetonitrile) on the adsorption process was studied via an Analytical linearized Poisson-Boltzmann algorithm.

In this study, the COD and TOC in H2O2-HCO3– oxidation system containing potassium hydrogen phthalate were determined by UV spectrophotometry (260-310 nm). The pH and H2O2 concentrations were investigated as factors influencing the absorbance measurements. The obtained standard curves were Abs = (3.10±0.04)x103xCOD - (0.015±0.003) (R2=0.9996) with LOD of 5.1 mg O2/l and LOQ of 13.6 mg O2/l, and Abs = (0.008±0.0001)xTOC - (0.015±0.003) (R2=0.9996) with LOD of 1.6 mg/l and LOQ of 5.4 mg/l. The method was applied to monitor the degradation of potassium hydrogen phthalate by the H2O2-HCO3– oxidation system. The results revealed that the COD and TOC removal efficiencies reached ~85% after 90 minutes of UVC irradiation. The UV spectra and HPLC chromatographs showed that no aromatic compounds were obtained in the degradation products.

Bisphenol A (BPA) is a precursor chemical to produce polycarbonate plastics and epoxy resins that have been widely used in the world with many essential daily applications. BPA is considered one of the endocrine-disrupting chemicals in animals, which causes harmful effects on health. Besides, BPA originates from resins and consumer products after use has been released into the environment. To assess the contamination level of BPA in surface water, this study collected and analysed water samples from rivers and lakes in the centre of Hanoi. The average concentration of BPA in 45 surface water samples was 76.8 ng/l (6.6-284 ng/l). The highest concentration of BPA was found at the surrounding area of the wastewater treatment plant in Yen So (177 ng/l), followed by the Yen So lake (86.9 ng/l), To Lich and Nhue rivers (~80 ng/l), Lu, Set, Kim Nguu rivers (~60 ng/l) and the lowest level in West Lake (20.1 ng/l).

In this research, a novel CuFe catalyst was fabricated using a simple, single-step electrodeposition method on a traditional Cu electrode. CuFe films from various electrodeposition baths with different Cu and Fe ratios were prepared by chronopotentiometry and characterised by X-ray diffraction (XRD), Scanning electron microscope (SEM), Energy dispersive X-ray analysis (EDX), and Pb underpotential deposition (Pb-UPD). The Cu electrode coated with CuFe8020 (from electrodeposition bath containing 80% Cu and 20% Fe) showed the highest reduction current among the film produced. The Cu electrode coated with CuFe8020 exhibited three times higher nitrate reduction efficiency and less undesired products like NO2− và NH4+ than the traditional Cu.

Calcium alginate bead (CAB) is a good adsorbent of heavy metal ions; however, CAB has a small specific surface area, limiting its applications in the removal of heavy metals in water treatment. In this study, alginate is denatured with activated carbon and surfactants to increase the porosity of the material and improve the adsorption capacity of the Ni(II) ion. Initial undenatured calcium alginate bead is almost no pores and a very small specific surface area (~0.04 m2/g). After modification, the porous composite made from alginate combined with active carbon and surfactant (P-CAB) has a large specific surface area ~160 m2/g, 4,000 times higher than CAB. The results of the Ni(II) ion adsorption study also showed that the maximum adsorption capacity of porous composite (qmax of 53.76 mg/g) significantly improved by 8.3 times than the adsorption capacity of CAB (6.48 mg/g).

IMPLEMENTASI METODE IDSAODV UNTUK MENDETEKSI SERANGAN BLACK HOLE PADA JARINGAN MANET
Authors: Pakpahan Charles Blanov Hasudungan , Agustini Siti
Published: November 2021

MANET adalah sekelompok node yang membentuk kesatuan dan mengirim paket kepada node yang lain. Namun dari segi keamanan, MANET sangat rentan terhadap berbagai macam serangan. Serangan black hole merupakan jenis serangan pada jaringan yang dapat menyerap network traffic dan menjatuhkannya. Cara kerja dari serangan black hole adalah dengan berpura-pura memiliki rute yang cukup fresh ke semua tujuan yang diminta oleh semua node dan menyerap semua network traffic. Saat node sumber melakukan broadcast pesan RREQ untuk node tujuan, node black hole akan segera merespon dengan pesan RREP yang berisi informasi sequence number tertinggi dan pesan ini dianggap seolah-olah datang dari node tujuan atau dari node yang memiliki rute yang cukup fresh ke node tujuan. IDSAODV merupakan suatu routing protokol yang digunakan untuk meminimalisir efek dari black hole. Protokol IDSAODV akan memeriksa paket RREP dari node black hole untuk jalur minimum ke tujuan dan maksimum sequence number tujuan. Protokol IDSAODV akan membuang paket RREP pertama yang datang dari node black hole dan memilih paket RREP kedua yang datang dari node tujuan. Pada penelitian ini akan dilakukan uji coba serangan black hole pada lingkungan MANET dengan jumlah node sebanyak 100, 110, 120, 130, 140, dan 150 dengan menggunakan routing protokol AODV dan IDSAODV. Dari percobaan tersebut didapatkan hasil peningkatan Packet Delivery Ratio (PDR) paling tinggi sebesar 47,36%, peningkatan Throughput sebesar 156,78 Kbps dan penurunan End-to-End Delay sebesar 27,62 ms.

Published: November 2021

Notions of Electromagnetism and Special Theory of Relativity (STR) require important mathematical knowledge applied to theoretical physics. Recognizing pedagogical difficulties in the teaching of theoretical physics, the Theory of Didactical Situations (TDS), which consists of a set of practices that aim to contribute to the improvement of mathematics teaching. In this context, the present work is motivated to present a set of practices based on TDS with a focus on teaching Electromagnetism and STR, where problems that require an understanding of the transformations of Galileo and Lorentz. Specifically, the didactic situation is constructed by means of four problem proposals, while in the adidatic situation, the student is invited to understand the roles of these transformations in the study of these problems. Ultimately, the relevance of the educator in the institutionalization situation is reinforced, a moment when it must be clarified how all mathematical relations are strongly related to physical principles.

Published: November 2021

Este artigo é parte constituinte de uma pesquisa de mestrado, que está em curso, e tem como objetivo apresentar as abordagens circulantes nas práticas pedagógicas que proclamam a integração curricular no âmbito do Programa Nacional de Integração da Educação Profissional à Educação Básica na Modalidade de Educação de Jovens e Adultos (PROEJA). Trata-se de uma pesquisa bibliográfica, do tipo Estado do Conhecimento, com fins exploratórios e abordagem qualitativa. Foi definida como fonte de coleta de dados as produções acadêmicas do GT18 - Educação de Pessoas Jovens e Adultas apresentadas nas Reuniões Científicas Nacionais da Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPEd) sobre esse Programa, no período de 2006 a 2017. A organização e o tratamento dos dados foram realizados com base na análise de conteúdo temática proposta por Bardin (2016) em diálogo com estudiosos do campo histórico-crítico, como Saviani (2003, 2013), Ciavatta (2005, 2011), Ramos (2008) e Galvão, Lavoura e Martins (2019). Os dados revelaram a inexistência de estudos que tratam da integração na oferta de concomitância e que há hegemonia de uma prática curricular fundamentada na Metodologia de Projetos, cujo cerne do currículo são os conhecimentos advindos do cotidiano dos alunos. Indicam, também, que os desafios da integração persistem, demandando a realização de pesquisas tanto no campo da formação de professores quanto no âmbito das práticas pedagógicas.
