Adaptive Coding is Optimal in Reinforcement Learning
Authors: Rustichini Aldo , Palminteri Stefano , Soukupova Magdalena
Published: January 2023

Adaptive coding is defined as the adjustment of parameters of a cognitive process as a function of the task's statistical properties. Our aim is to demonstrate that adaptive coding maximizes performance in situations where decision-making follows a reinforcement learning process (RLM), and test empirically test the predictions of our model. We first provide a detailed model of adaptive coding of reward in a RLM and study its performance, measured in expected value obtained from chosen options. In our model, the parameters modulating learning adjust optimally according to the information on outcomes. Their values are modulated by the trade-off between exploration and exploitation. When feedback is complete, exploration is redundant, and parameters adjust to maximize exploitation. When feedback is partial (only provided on the chosen option) an optimal compromise is reached between exploration and exploitation. We test these predictions in a set of experiments with complete and partial feedback. We find support for the hypothesis that coding is adaptive, and has the linear form we hypothesize. The design allows us to discriminate between two possible formulations, finding support for the hypothesis that adaptation is specific to reward encoding. We also find that the representational bias introduced in choice by the adaptive coding is transitory and is corrected when appropriate information is provided to participants.
Philosophy of Perception in the Psychologist’s Laboratory
Authors: Morales Jorge , Firestone Chaz
Published: January 2023

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, and which ‘subjective’? What properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches.
Problems in Research Practices and Reporting, Clarifying, Understanding, and Potentially Resolving Mixed Findings and Uncertainties in Health Message Framing Literature: Agenda and Solutions for Moving Forward
Authors: Yeung Siu Kit
Published: January 2023

Framing in terms of gains, losses, nonlosses, or nongains, following compliance or noncompliance, can sometimes be effective in motivating healthy attitudes, intentions, and behaviors, but there have been unresolved mixed findings and uncertainties in the health message framing literature. First, operational definitions and contents of gain-framing and loss-framing, as well as often overlooked nonloss framing and nongain framing, have been unclear and sometimes confusing, with contradictory findings comparing these conditions. Moreover, there have been mixed and null findings in risk and message framing, a few null findings in the relatively robust regulatory fit literature, and concerns regarding generalizability of findings especially regarding age and culture. I discuss these issues, report an Open-Meta-Science assessment on the health message framing literature, and propose possible solutions to each of these problems. Most Open Science practices are rarely implemented in this literature. To move forward, Openness, Transparency, Reproducibility, Rigor, and Clarity, rigorous Replications-Extensions, Meta-Analyses and Systematic Reviews with advanced and more reproducible methods, Adversarial Collaborations, Big Team Science, and other Open/Meta-Science practices may help resolve some of controversies and uncertainties and may facilitate theoretical evaluations and advancements.
Challenges Encountered by Mathematics Teachers in ICTs Implementation
Authors: Parajuli Kharika Devi , Koirala Bidhya Nath
Published: January 2023

Information and communication technologies (ICT) have a great deal with teaching and learning processes to conceptualize abstract concepts in mathematics. The objective of this study investigated the challenges encountered by secondary-level mathematics teachers while implementing ICT-based training in a classroom in teaching. We used interpretive inquiry as an approach to research. As the study tools, we used in-depth interviews, observations, and generated textual data. We analyzed the data by adopting the data's sequential coding, categorizing, and thematizing. We used constructivism as a theoretical lens to understand and explore the use of ICTs. We envisaged and generated the themes on challenges that are inadequate ICT-based professional development training and tools; lack of competency in technological/ pedagogical content knowledge; disempowering school actors; enduring 'one size fits for all'; structured curriculum; lack of infrastructure and ICT tools and hegemony of traditional classroom practices. The significance of the use of ICTs has been recognized in public schools in Nepal. There was also evidence that the current practice of ICT-based teacher education and development was not excess in developing skills and knowledge to use ICT in their classroom.

Authors: Dahal Khet Raj , Bhusal Bhesh Raj
Published: January 2023

Flood in Tinau River is very common since past decades. It has damaged several houses, cultivated land and live stocks in the past and continues till the date. Hundreds of hectares of cultivated lands have been deposited with sand and debris making the land unsuitable for farming. The governments of Nepal and local bodies have been launching projects for flood control. Various types of structures were built in the past. Millions of Nepalese Rupees have been invested for river training works. However, the river training works is not functioning well. This study was conducted during the period from March 2019 to April 2020. The objective of this study is to evaluation the effectiveness of river training works with especial focus on Tinau River in Rupandehi district of Nepal. Field observation, in-depth interview, focus group discussion and questionnaire survey were the major tools used for the field investigation. The study found that the extraction of river bed materials and unmanaged catchment area are also the causes of the ineffectiveness of the river training works. It also includes lack of monitoring and supervision, socio-political pressure and lack of enforcement of law and policies. Similarly, some other causes are inadequate co-ordination between line agencies, inadequate plan and policies and lack of awareness are the minor causes of ineffective river training works. Furthermore, inadequate maintenance of built up structures, irresponsible of beneficiary group, unmanaged population growth at catchment area were also found causes behind sustainability of the river training works. The study would like to suggest that the river bed extraction should be conducted in a balanced way. And, hydrological, geological and geotechnical studies should be conducted in detail before design of the river training structures.

Published: January 2023

Water Distribution Network earlier will have challenge in fulfilling the growing need of water supply. Forecasting and monitoring the flow, pressure, demand, and quality of water in water distribution network are key requirement for sustainable and reliable water supply. Lekhnath city, due to the recent merger with the biggest metropolitan city of Nepal, Pokhara, has created the rapid growth of population resulting to haphazard pipeline extension in this area. For hydraulic analysis of Lekhnath Small Town Water Supply Distribution Network, one of the networks i.e., Shishuwakhudi distribution network was faced with problem analysis. This hydraulic analysis is a part of on-going doctoral research and Youth-led Initiative ‘drinkPani’ on ‘Water Supply and Quality Monitoring using Emerging Technologies’ where capacity building of Youth and Women through data-driven engagements (Water-informatics) is one of the core targets in the overall project-work package. The preliminary analysis of water quality was also derived from Young Water Volunteers (YWVs) under the research work on Youth-led Participatory Sensing (YPS) Model to enhance drinking water security of the study area. The Shishuwakhudi Water Distribution Network (WDN) supplies water to 1138 household at present and consisting of 41 junction nodes and 11.2km distribution pipeline distributing water from a reservoir. With field survey, households at each node of the network were determined. Demand driven analysis using EPANET was done to determine the pressure deficit at various nodes. Demand pattern based on design guideline was adopted for analysis. At present scenario, four nodes at end of the network showed negative pressure at peak hours (5 am- 7am). At other times, the pressure was above 10m head. Demand was forecasted for 10 years from now by projecting the household population based on growth rate of census 2011. When projected to future scenario, the existing pipeline showed only 17% reliability with a minimum pressure requirement of 10 m head as per norms of urban water supply project in Nepal. Genetic algorithm was used for optimization of the Shishuwakhudi Network with total cost of replacing pipes as an objective function with pressure constraint of minimum 10m head. With 500 generation of run, the optimal diameter for each pipe was obtained that gave optimal cost of NRs 4,21,50,917 (USD 359,690.64). This optimization helps in selecting the proper pipeline network for future expansion to fulfil the growing need of water demand.

Published: January 2023

Yield growth in the Southern Steppe is impossible without irrigation with the introduction of mineral and organic fertilizers, so the repair, restoration, and construction of new irrigation networks are one of the main tasks of regional and district water management. For the repair of water management networks, regulation of pools of irrigation systems it is necessary to use inexpensive effective methods of the establishment of their technical condition. Such methods are geophysical, which allow to identify the areas of filtration, flooding, violations of protective screens in the control pools of irrigation systems. The necessity of localization of areas of filtration water losses to concentrate repair and restoration works in the most disturbed zones is scientifically substantiated, which will significantly reduce the cost of time and money and increase the overall efficiency of the structure.
Pneumonia of Chest X-Ray Images Detection using VGG Architectures
Authors: Nyaupane Bal Krishna
Published: January 2023

Pneumonia is one of the world's most frequent diseases. Pneumonia, a serious respiratory infection, damages the lungs and makes it difficult to breathe. Chest X-ray scans are one of the most significant and common procedures for diagnosing pneumonia condition. An effective model for the identification of pneumonia based on digital chest X-ray pictures is proposed in this paper, which could help radiologists make better decisions. This is a supervised learning technique in which the proposed model predicts the outcome depending on the dataset's image quality. In this research, Kaggle dataset has been used to train the model. To improve training and validation accuracy, fine-tuning of Visual Geometry Group (VGG) pre-trained model are conducted with different hyperparameters. The deep Convolutional Neural Networks (CNNs) based VGG-16 and VGG-19 architectures are used to extract features from given chest X-ray images. These features are then used for classification. In addition to the accuracy and F1-score as an evaluation matrix, the results of pre-trained models are compared using the model loss, and model accuracy graphs. The model's performance in detecting pneumonia demonstrates that the proposed VGG pre-trained model can efficiently categorize normal and pneumonia chest X-rays images in practice. As a result, the proposed model can be utilized to make a speedy diagnosis of pneumonia and can assist radiologists with their work.
Effect of Mn Doping on the Electronic and Magnetic Properties of Full Heusler Alloy Co2FeSi
Authors: Pokhrel Pramila Kumari , Kaphle Gopi Chandra
Published: January 2023

Heusler compounds are one of the largest families of ternary intermetallics with broad range of applications. In this work, we inspected the electronic and magnetic properties of full Heusler alloy Co2FeSi and the effect induced by doping Mn atom on those properties. We employed plane wave pseudo-potential method based on DFT framework implemented in Quantum ESPRESSO code using PBE type of functional for exchange correlation energy. The calculation demonstrates that Co2FeSi exhibits metallic nature in the majority spin state and semi-conducting nature in minority spin state with indirect energy gap of ≈ 0.132 eV and shows chances of weakened half-metallicity as indicated by the presence of band gap below fermi level. The calculated total magnetic moment is 5.44 μB/cell which is found to be deviated from Slater-Pauling rule M = NV − 24 for full Heusler compounds. The site selection for doping was based on the empirical rule for atomic occupation established for Heusler alloys and the calculation of formation energy. The calculation of formation energy at B and D site showed B site as more favorable for doping for both 25% and 50% concentration. At 25% Mn concentration, calculation shows Co2FeSi has typical metallic behavior for spin-up electrons, but semi-conducting behavior with decreased gap below fermi level for spin-down electrons showing no half-metallicity whereas for 50% Mn concentration the gap gets broadened by 0.089645 eV. The calculated magnetic moment for 25% and 50% Mn doping is 21.93 μB/cell and 21.69 μB/cell respectively. Our calculation depicts that the chances of half-metallicity decreases for 25% concentration of Mn atom and increases for 50% Mn concentration.

Background: In Indonesia, there are 17 – 59% of school-age children who do not eat breakfast, school children who skip breakfast are 2.8 times more likely to suffer from obesity. The prevalence of obesity (BMI/U) for school-age children (5-12 years) in Indonesia is 9.2%, an increase of 1.2% compared to 2013. One of the ready-to-eat products that school-age children can consume at breakfast is flakes cereal. The protein and fat content of jali is higher than rice, corn, millet and sorghum. The dietary fiber content of jali seeds (4.3%) was higher than that of corn (2.8%). The HMT method was used to produce jali flour with suitable characteristics for flakes. Soybeans contain plant protein sources reaching 35%. Soybean sprout flour with water blanching contains the highest fiber content (30%) compared to other bean sprout flour. Methods: Experimental research method with 3 treatment levels and 3 repetitions. Results: The lower the proportion of HMT modified jali flour and the higher the proportion of soybean sprouted flour, the water, ash, protein, fat, and crude fiber content of the flakes increased but the carbohydrate content decreased. The lower the proportion of modified HMT jali flour and the higher the proportion of soybean sprouts flour, the panelists' preference for the aroma, taste, and texture of flakes decreased, except for the color parameter, the panelists preferred P2. Conclusion: The substitution of cereal flakes based on HMT modified jali flour and soybean sprout flour gave a significant effect on chemical quality, nutritional quality, and aroma organoleptic quality. However, it has no significant effect on the organoleptic quality of color, taste and texture. The level of treatment P2 (75:25) was determined as the best treatment level.

Implementation of the transparency laws in Catalonia
Authors: Villoria Manuel , Cerrillo-Martínez Agustí , Ponce-Solé Juli
Published: January 2023

Despite theoretical forecasts that have linked transparency policies with improvements in the fight against corruption, increased trust in institutions, and the development of quality in governments, several empirical studies have shown that this connection is not so simple. For it to happen, regulations of sufficient quality must be embedded in a holistic policy of good governance and adequately implemented. The transparency policy cannot generate the desired impacts if it is not implemented in the first place. The transparency policy of the governments of Catalonia does not seem to have had the desired effects, despite being of sufficient quality and being formally inserted in a holistic framework of good governance. The hypothesis this article attempts to test is the weakness of the implementation of Act 19/2014 as the cause of the non-existent or piecemeal outcomes. An exhaustive evaluation of the law’s implementation was conducted to test the hypothesis, with five series of surveys in five years (2015–2020) sent to more than 1,000 entities bound by the law, a review of transparency portals, a quality analysis of resolutions on the right of access, a quality analysis of citizens’ charters and codes of conduct, the use of the mystery shopper technique, and in-depth interviews with public decision-makers. The analysis results do not guarantee that the relative failure in impact is due to weak implementation of the law. However, it also cannot be ruled out that failure to implement some aspects of the rule influences its lack of effectiveness.

ANALISIS HYBRID CONTRACT PADA PRODUK RAHN EMAS STUDI KASUS PEGADAIAN SYARIAH SOLO BARU (SHARIA STANDARD AAOIFI NO. 19 TAHUN 2004 TENTANG LOAN ATAU QARDH)
Authors: Nurdiana Dewi
Published: January 2023

AAOIFI menyatakan dalam Mikyar (19) ayat (7) tentang qardh bahwa, penggabungan akad ba’i, ijarah, mu’awadah tidak boleh dilakukan dengan akad qardh, seperti dalam produk rahn emas yang saat ini berlaku di pegadaian syariah. Penelitian ini bertujuan untuk menganalisis penerapan akad rahn emas pada pegadaian syariah Solo Baru. Serta menganalisis hybrid contract yang terjadi pada produk tersebut. Penelitian ini berjenis penelitian lapangan dengan spesifikasi penelitian secara deskriptif analitis. Produk gadai emas syariah (rahn emas) di pegadaian syariah Solo Baru merupakan jenis pembiayaan yang diberikan kepada nasabah dengan jaminan barang gadai berupa emas. Transaksi gadai emas syariah (rahn emas) di pegadaian syariah Solo Baru menggunakan akad qardh, rahn dan ijarah. Adanya qardh sebagai akad awal terjadinya utang-piutang yang menjadi pangkal dari terjadinya gadai (rahn) dimana niat awal nasabah datang ke pegadaian syariah untuk mendapatkan pembiayaan berupa utang dan akad ijarah atas upah penyimpanan emas sebagai jaminan dalam akad rahn yang digadaikan. Bahwa sebenarnya penggabungan akad pada produk rahn emas yang dipraktikkan di pegadaian syariah cabang Solo Baru yang sebelumnya telah dilarang dalam hadits Nabi merupakan suatu keniscayaan. Keberadaan akad ijarah dalam produk ini memiliki tujuan yaitu sebagai kebutuhan dalam menjaga dan memelihara barang yang dijadikan jaminan utang yang telah diberikan oleh pegadaian syariah, sehingga boleh dilakukan. Hal ini tentu berbanding terbalik dengan penggabungan akad ba’i dan qardh bahwa penggabungan akad tersebut tidak ada kebutuhan, akad bai’ bukan merupakan sesuatu yang dibutuhkan.

Metode yang digunakan dalam penelitian ini untuk mengetahui nilai kebutuhan air digunakan metode Blaney- Criddle dan untuk mengetahui tingkat optimasi distribusi air irigasi digunakan metode   dinamik   stokastik.   Hasil   penelitian   ini   menunjukkan   bahwa   nilai kebutuhan air mengalami peningkatan pada tahun pertama setelah ekstensifikasi yaitu pada tahun 2019 dengan nilai kebutuhan air terbesar mencapai 759,82 ltr/dtk/ha. Hal ini dikarenakan bertambahnya luas lahan pada daerah irigasi tersebut. Nilai kebutuhan air pada tahun 2021 kemudian mengalami penurunan menjadi sebesar 612,38 ltr/dtk/ha yang diakibatkan oleh intensitas curah hujan pada tahun 2021 cukup besar sehingga kebutuhan akan air pada daerah irigasi tersebut berkurang. Dengan nilai kebutuhan air tersebut dilakukan optimasi distribusi  air  irigasi  sehingga  didapatkan  nilai  efisiensi  distribusi  air  irigasi sebelum dilakukan optimasi yaitu sebesar 81,82% (luas lahan yang terairi 18 ha) dan setelah dilakukan optimasi efisiensi distribusi air irigasi akan mengalami peningkatan menjadi sebesar 92,95% (luas lahan yang terairi 20,45 ha).Kata Kunci: Ekstensifikasi, Kebutuhan Air, Optimasi, Dinamik Stokastik

This article examines various aspects of identities conveyed by urban populations, factors of transformation and development of urban spaces, and historical memory as tools for the socialization, stratification, and integration of a polyethnic society in the Republic of Sakha (Yakutia). The empirical base of the study is a variety of material, including a questionnaire survey of the urban population of Yakutia, spontaneous polls, and in-depth expert interviews. The novelty is the research strategy itself, aimed at identifying all the listed actors through the prism of symbolic representations. The study of the symbolic value of the northern cities of Yakutia as informational and cultural spaces, understanding the heritage as a certain mediative mental-material cultural layer with symbolic codes and texts, provides key registers for considering the fundamental problems of the spatial and socio-cultural development of territories in general. The results of the study show that the political identity of the population of Yakutia has been formed according to the historical memory of the Soviet past. A trend towards positioning the region as “northern” or “arctic” has emerged in recent years, which also depends on government policy in the Arctic.

ASSESSMENT OF THE QUALITY AND SAFETY OF MINERAL ADDITIVES FROM SEAFOOD SHELLS IN THE DIET OF POULTRY
Authors: Razumovskaya E. S.
Published: January 2023

One method of preventing mineral metabolism diseases in birds is to enrich feed rations with natural additives derived from non-traditional raw materials. A source of minerals can be, in particular, mineral crumbs obtained by processing seafood shells. In this regard, the research aimed to assess the quality and safety indicators of mineral supplements made from seafood shells. The authors in the article described the technological process and equipment for obtaining mineral chips and mineral mixtures. The study’s results indicate the high quality and safety of seafood shells. The determined insignificant content of foreign and metal magnetic impurities and the absence of pathogenic microorganisms prove its suitability for feeding. In addition to safety indicators, one of the most important factors is the mass fraction of calcium and magnesium carbonates involved in the mineral metabolism of the poultry body. These indicators of the mineral crumb and mineral mixture were 99.75% and 95%, respectively. The obtained result exceeds by 8.5-8.9 % the similar hand of lime flour (85 %), also intended for introduction into the ration of poultry.
