Authors: Gao Qinyan
Published: July 2023

The rapid development of art and design nowadays puts forward higher and higher requirements on the teaching of art and design, and the bottleneck phenomenon of cultivating innovative ability in art and design is becoming more and more prominent. To study the innovative teaching strategy of art design, this paper proposes a creative new teaching strategy based on the VAR model for the current problems in art design teaching. The experiment examines the feasibility of the strategy in three dimensions: student satisfaction, innovation rating, and comprehensive rating of teaching outcomes. The results showed that the innovative teaching strategy increased the percentage of satisfied students by 29.7% and decreased the percentage of dissatisfied students by 50%. The mean value of students’ innovation rating in the traditional teaching mode was 58.3, while the mean value of students’ innovation rating in the VAR model-based teaching method was 67.3, an increase of 15.4%, showing that the innovation of teaching was recognized. In terms of the overall rating of teaching results, the mean value of traditional teaching was 61.5, and the mean value of innovative teaching was 81.3, an increase of 32.1%, which showed that the teaching effect was significantly improved. Moreover, the standard deviation of traditional teaching scores reached 10.01, which is much larger than 5.87 under innovative teaching. The adoption of an innovative teaching strategy can greatly shorten the gap between art and design students. In conclusion, the innovative teaching strategy proposed in this paper can be well adapted to the art and design classroom, which can be well accepted by students and improve the teaching effect.

The orientation of music teachers’ talent training and the construction of talent training models are the core issues of concern for the reform of music education majors. Facing the new requirements of society for music education professional talents training in the new period, this paper proposes an improved talent training model based on the ADDIE model by studying the current situation of music education professional talents training from the perspective of adapting to the development needs of music curriculum reform in basic education. From the assessment of students’ and teachers’ evaluation and acceptance of the model, the mean value of students’ evaluation scores increased from 64.7 to 75.7 compared with the original training model, an increase of 17.00%. The mean teacher evaluation score increased from 67.0 to 72.7, an increase of 8.51%. It is evident that the talent development model has improved and is accepted by students and teachers. In terms of the acceptance of the training model proposed in this paper, the percentage of students who strongly agree with it has increased by 19.8%, the percentage of students who can accept it has increased by 20.2%, and the percentage of students who cannot adapt to the teaching model has decreased by 6.1 percentage points, with a comparative decrease of 20.3%. Teachers were also more accepting of the new training model, and the percentage of those who could accept it increased by 5.3 percentage points and 7.17% in comparison. In conclusion, the talent cultivation model of music education based on the ADDIE model can be well adapted to the teaching classroom of colleges and universities and also meets the needs of the country and society for music teachers in the new era, which is conducive to the cultivation of composite talents who are highly educated and have a solid theoretical foundation and excellent practical ability.
Transmutation and Reconstruction of Enterprise Management Model Framework Based on Improved Markov Model
Authors: Xu Haiyan
Published: July 2023

With the deepening of socialization, the requirements for enterprises are getting higher and higher, which also prompts enterprises to innovate their management models. To enable enterprises to find the correct way to reconfigure their corporate management models, a prediction method based on an improved Markov model is used to forecast the direction of corporate management model reconfiguration. In this paper, the residuals generated by fitting GM (1, 1) at each time node are considered as the expected output values of positive and negative two random states under the state probability distribution, and the squares loss function of the residuals is established as the objective function. To obtain the minimum value of the squares loss function, the gradient descent algorithm is applied to approximate the optimal values of the probability intensity and the pending coefficients of the Kolmogorov equation under the condition of the available small amount of information, and then the Markov model correction value is determined to correct the prediction results of GM (1, 1), which effectively improves the reasonableness and feasibility of the Markov model to predict the results of the enterprise management model architecture reconstruction. The results of the calculation of the data show that According to the calculation results of the data, it can be seen that the gradient descent Markov model prediction results reduce the average relative errors of the three sets of data to 0.214%, 1.582%, and 4.134%, respectively, which is better than various other prediction models. It shows that the gradient descent algorithm based on the squares error loss function under the Markov model can effectively improve the reasonableness of the transfer probability intensity, enhance the reasonableness and reference value of the prediction results, and provide a practical direction for enterprises to reconstruct and transmute their management models under the condition of small sample data.

Authors: Tu Shipei
Published: July 2023

During rapid chemistry, cultural convergence, and technological advancement, music education management has increasingly become an interdisciplinary discipline integrating musicology, pedagogy, management, educational economics, ethics, and related technological sciences. However, in the current structure of general music education, there is still a discrepancy between the reality and the ideal in terms of philosophy, content, methods, and evaluation in the practice of family, school, and social music education. In order to solve such problems, this paper focuses on the current knowledge-tracking mechanism in music learning education. Firstly, we analyze and compare the DKT model, DKVMN model, and LSTM neural network and propose a new LMKT model after studying the advantages and disadvantages. In order to analyze the characteristics of student learning data, the student learning process was observed visually on two online publicly available real data sets, ASSISTMents2009 and ASSISTMents2015. The results show that the AUC value of the LMKT model proposed in this paper (73.83%) is 4.62% and 1.15% higher than that of the DKT model (69.21%) and the DKVMN model (72.68%), respectively, and that knowledge tracking is less effective as the number of clusters increases when the number of student clusters K is greater than 6. When the number of K is less than 6, the knowledge-tracking effect becomes better as the number of clusters increases. It is finally concluded that the LMKT model shows a better tracking effect, and the clustering feature improves the knowledge-tracking ability of the model.

Published: July 2023

AA2024-T351, a heat treatable aluminum alloy, has a high strength to weight ratio and good fracture resistance and has application mainly in the aircraft and aerospace sector. However, the alloy is susceptible to high corrosion because of the secondary phases (Al2Cu) present in the matrix. With an objective to increase the corrosion and wear resistance, Friction Stir Processing is applied to engineer the morphology and dispersion of the Al2Cu phase in the alloy. The friction stir processing trials are performed by varying the tool rotation speed, tool traverse speed, and shoulder diameter, as the properties of the friction stir processed region depend on the proper selection of process parameters. A hybrid linear-radial basis function model is developed to explore the effect of tool rotation speed, tool traverse speed, and shoulder diameter on the grain size, microhardness, corrosion rate, wear rate, and corrosion potential of the friction stir processed AA2024-T351 alloy. The predominant corrosion mechanism and wear regimes in AA2024-T351 alloy are understood from the characterization study on the surface morphology and elemental analysis of the corroded and worn specimens. The optimum friction stir processing parameters that improve the grain refinement, microhardness, corrosion resistance and wear resistance of AA2024-T351 alloy are established.

On Emblematic Meanings of Traditional Medicinal Herbs: Local Wisdom Values in the Perspective of Culture-Specific Ecopragmatics
Authors: Rahardi R. Kunjana
Published: July 2023

The research on emblematic meanings of traditional medicinal herbs is descriptive qualitative research. The data of the research were mostly obtained from texts containing descriptions of local wisdom values found in the names of traditional medicinal herbs. The data were also obtained from the researcherâ€™s intuitive ideas as a member of the community where the local wisdom is shared and lived by. The data were obtained by using two methods, namely observation, and speaking methods. The observation method was carried out by using a note-taking technique, while the speaking method was carried out by using the recording technique. The conversation between the researcher and the research informants was recorded and then transcribed to find the required data. The participatory interview method employed an in-depth interview to obtain the description of local wisdom values specifically. The proliferation of data was concluded by classifying and typifying the data after being identified from the sources. Data analysis was carried out using the distributional method with a direct element division technique to cover the linguistic dimensions of this ecopragmatic research. The data was also analyzed and interpreted by using the identity method to cover the pragmatic dimensions in this research. The research results show that: (1) the emblematic meanings are truly found in several traditional medicinal herbs in some parts of Indonesia; (2) the emblematic meanings of the traditional medicinal herbs are classified based on their shapes, uses, directions of the plantâ€™s flower, the smell of the plants, and the origins.

Published: July 2023

Актуальность исследования по теме организация обучения математике в начальных класса заключается в том, математическое развитие играет важную роль в развитии ребенка, так как математические знания, сформированные в начальных класса являются фундаментальными для всех остальных знаний, которые человек будет приобретать в будущем и «наслаивать» их на имеющуюся базу. Интегрированный курс начальной математики включает в себя арифметические, геометрические и алгебраические разделы, что позволяет детям с младшего возраста понимать универсальность математических способов познания мира. Они усваивают начальные знания математики, связывая их с окружающей действительностью и другими учебными предметами. Разрешение задач, предлагаемых на уроках, помогает развивать познавательные способности и заинтересованность в расширении математических знаний у детей. Для комфортного преподавания математики необходимо создание благоприятных условий на уроках для общего интеллектуального развития каждого ученика. При этом важно учитывать возрастные характеристики и возможности каждого ребенка, обеспечивая достаточную математическую подготовку для дальнейшего обучения. В данной статье рассматривается теоретический аспект изучения организации обучения математике в начальных классах, методы обучения детей математике, а также программы, в которых развернуто рассматривается раздел математики.

The relevance of the study on the organization of teaching mathematics in the primary grades lies in the fact that mathematical development plays an important role in the development of the child, since the mathematical knowledge formed in the primary grades is fundamental for all other knowledge that a person will acquire in the future and “layer” them to the existing base. The integrated elementary mathematics course includes arithmetic, geometric and algebraic sections, which allows children from a young age to understand the universality of mathematical ways of knowing the world. They learn the basic knowledge of mathematics, connecting them with the surrounding reality and other academic subjects. Solving the problems offered in the lessons helps to develop cognitive abilities and interest in expanding mathematical knowledge in children. For comfortable teaching of mathematics, it is necessary to create favorable conditions in the classroom for the overall intellectual development of each student. At the same time, it is important to take into account the age characteristics and capabilities of each child, providing sufficient mathematical preparation for further education. This article discusses the theoretical aspect of studying the organization of teaching mathematics in primary school, methods of teaching children mathematics, as well as programs in which the section of mathematics is considered in detail.
OPTIMIZATION OF PLANTING PATTERNS ON PADDY PLOTS IN PURI VILLAGE, PURI DISTRICT, MOJOKERTO REGENCY, EAST JAVA USING A LINEAR PROGRAM
Authors: Wiguno Dwi Prastyo , Saves Faradlillah
Published: July 2023

The research site is located in one of the hamlets in Puri village, which has an agricultural land area of approximately 25 hectares. Because of its fertile soil conditions, the land is very suitable for agriculture. However, the agricultural productivity in Puri village has decreased due to changing weather conditions. Puri village, Puri district, Mojokerto regency, has a flat landscape. The duration of the dry season is slightly longer, affecting the availability of water and causing a change in the initial cropping period. As a result, the cropping pattern in the village is not appropriate, leading to a decrease in agricultural productivity. To solve these problems, an optimal cropping pattern needs to be planned to increase agricultural productivity in the village. In order to plan the optimal cropping pattern, the first thing that needs to be done is to calculate the availability of existing water. Then, the need for irrigation water should be calculated. Using the two sets of calculation data, the optimal cropping pattern can be planned with linear program. The analysis is revealed that Puri village has an optimal cropping pattern with a Paddy-Corn-Corn cropping model and an initial planting period in December period 2.
GENERATION OF SYNTHETIC RAINFALL DATA IN SEKAYAM SUB-WATERSHED BASED ON TRMM SATELLITE RAINFALL DATA CORRECTION EQUATION
Authors: Iwansyah Iwansyah , Soeryamassoeka SB. , Yulianto Eko
Published: July 2023

The hydrological analysis is the first stage of the review in waterworks planning. Hydrological analysis necessitates the availability of sufficient data. Data availability tends to have several problems, including a lack of availability, incomplete/empty data, a smaller number of stations, observers, and observation systems, data entry that is still manual, and slow data collection. One possible solution is to use rain satellites. However, TRMM data must be evaluated for field suitability. TRMM (Tropical Rainfall Measurement Mission) rainfall data can help overcome this. TRMM is a NASA mission that uses weather monitoring satellite technology to monitor tropical rainfall. This is also the case for the Sekayam Subwatershed, part of the Kapuas River Basin.In the Sekayam sub-watershed, there are 14 (fourteen) rainfall observation stations managed by the Balai Wilayah Sungai Kalimantan (BWSK) I, but currently only 5 observation stations are still active, namely the SGU-01 Sanggau, SGU-03 Balai Karangan, SGU-06 Entikong, SGU-19 Semuntai and SC-01 Kembayan observation stations with data recorded up to 2019, while the other 9 (nine) observation stations do not have long continuous data, because there are years where rainfall data is not recorded. This is because the recording of rainfall on average stopped until 2005, or even some have stopped operating since the 1990s or early 2000s. This study aims to generate representative synthetic TRMM daily rainfall amount data for the Sekayam sub-watershed based on the correction equations obtained in a series of TRMM rainfall data validation analyses, so that it can be used as alternative daily rainfall data in water resources planning and management in the Sekayam sub-watershed. From the analysis, it can be seen that synthetic rainfall data in the Sekayam sub-watershed will be valid if it is generated with the linear model correction equation Y = 0.6708 X + 139.123 or can be interpreted as TRMM' = 0.6708 TRMM + 139.123.
Hypothetical pathways on glycoRNA biochemistry
Authors: Alonso-Gil Santiago
Published: July 2023

GlycoRNAs are recently discovered biomolecular structures whose medical relevance is key to understanding cell-cell communication. Research fields such as immunology and tumor research are developing theories around these novel conjugates located on the cell surface. The work of Bertozzi is a reference where the experiments show relevant physicochemical properties of the sialylated RNA conjugates. Going through the current enzymatic and chemical available data, in this work, we hypothesize on the possible biochemical pathways leading to N-glycosylation of RNA nucleobase. Based on the reactivity of glycoRNA with oligosylsaccharide transferases and the PNGase F hydrolase, we base our hypothesis on the conjugation of modified versions of the canonical nucleobases and the GlcNAc moiety through an amide-functionalized small linker. We assume that every nucleobase (A, C, G, and U) is modified following a different enzymatic pathway, but purine bases and pyrimidine bases share the same link to the anomeric carbon of the sugar (Ca), respectively: C7-CONH-Ca and C5-CH2-CONH-Ca.
Manifold Projection Image Segmentation for Nano-XANES Imaging
Authors: Tetef Samantha , Pattammattel Ajith , Chu Yong , Chan Maria , Seidler Gerald
Published: July 2023

As spectral imaging techniques are becoming more prominent in science, advanced image segmentation algorithms are required to identify appropriate domains in these images. We present a version of image segmentation called manifold projection image segmentation (MPIS) that is generally applicable to a broad range of systems without the need for training because MPIS uses unsupervised machine learning with a few physically motivated hyperparameters. We apply MPIS to nano-XANES imaging, where X-ray Absorption Near Edge Structure (XANES) spectra are collected with nanometer spatial resolution. We show the superiority of manifold projection over linear transformations, such as the commonly used Principal Component Analysis (PCA). Moreover, MPIS maintains accuracy while reducing computation time and sensitivity to noise compared to the standard nano-XANES imaging analysis procedure. Finally, we demonstrate how multimodal information, such as X-ray Fluorescence (XRF) data and spatial location of pixels, can be incorporated into the MPIS framework. We propose that MPIS is adaptable for any spectral imaging technique, including Scanning Transmission X-ray Microscopy (STXM), where the length scale of domains is larger than the resolution of the experiment.

Hunter-gatherer archaeology typically focusses on the details of subsistence strategies and material culture and, in the case of cemeteries, on various aspects of mortuary practices, beliefs, and social differentiation. This paper aims to look rather at patterns of change over time and space in how past hunter-gatherer cemeteries were used from Late Mesolithic to Early Bronze Age (~8600–3500 cal BP) in the Cis-Baikal region of Eastern Siberia. The approach is based on a Kernel Density Estimate methodology applied to 560 radiocarbon dates obtained for individual burials from 65 cemeteries and representing 5 distinct mortuary traditions. This enables a number of different types of analysis to be performed at different scales: (1) It is possible to examine the overall tempo of burial events at each cemetery or a group of cemeteries; (2) Within each cemetery the spatial patterns of the sequence of graves and burials can be analyzed further; (3) It is possible to compare the different cemetery-specific chronologies within the microregional or regional context; and (4) Although tentatively at this time, the spatiotemporal pattern of cemetery use over the whole region can be visualised. The spatiotemporal analysis of individual cemeteries shows that each one had its own pattern, some very distinct and clear in their characteristics, which relate to the role the cemetery played for the local group, and within the microregional or regional population. On the regional scale some broader patterns such as shifts in frequency of burial events between microregions within mortuary traditions are visible. However, at this scale the existing sampling biases require caution in assessment of the results and future fieldwork will help improve the analysis and insights. On the other hand, many of the individual cemeteries have been excavated in full and such comprehensive datasets already provide a range of entirely new and important insights into cemetery use by the Middle Holocene hunter-gatherers of Cis-Baikal.
Neolithic and Early Bronze Age of Cis-Baikal: Chronology and Dietary Trends

Analyses of radiocarbon dates (all corrected for the freshwater reservoir effect) and associated stable isotope values obtained from the skeletal remains of ~560 individuals provide many new insights about Middle Holocene hunter-gatherers (HG) of the Cis-Baikal region, Eastern Siberia. The new radiocarbon evidence clarifies the culture history of the region by defining better the boundaries between the chronological (archaeological periods) and cultural (mortuary traditions) units, as well as our understanding of the transitions between them. Furthermore, differences between the four archaeological micro-regions with regard to the timing and duration of these culture historical units have come into focus for the first time. In terms of dietary patterns, the Early Neolithic foragers of the Angara and Southwest Baikal trended towards a greater reliance on aquatic foods. A similar trend was found in the Late Neolithic Isakovo group on the Angara, while the Late Neolithic Serovo group in the Little Sea trended towards an increased dietary reliance on terrestrial game. In the Early Bronze Age HG, a mosaic of dietary patterns was found: some groups experienced dietary shifts (frequently emphasizing different foods), while other groups displayed stability. Such differences were found even between close neighbours. All these results suggest significant variation in patterns of culture change within and between archaeological periods, mortuary traditions, and micro-regions. Some cultural patterns developed at a quick pace, others much more slowly; some appear to have collapsed rapidly, while others probably went through a more gradual transition to a different pattern. Additionally, this large set of radiocarbon dates allows novel insights into patterns of cemetery use: some seem to have been used continuously, others only sporadically, and some show long periods of disuse. Moreover, some cemeteries of the same mortuary tradition were apparently in use substantially earlier than others were even established. In sum, Cis-Baikal Middle Holocene HG strategies underwent a range of changes not only at the boundaries between relevant culture historical units but also within such units. New insights suggest considerable spatio-temporal variation in the nature, pace, and timing of these developments.

Published: July 2023

The techniques and the principles used in DNA isolation play a vital role in the obtaining of a purified genetic material. In present study, we investigated the efficiency of seven genomic DNA isolation techniques in terms of isolated DNA concentration, yield and purity from internal organs, gills and muscle tissues of Notopterus notopterus. Isolated DNA quality was analysed through Nanodrod and PCR using mitochondrial COI genetic markers. Results showed that GeneJET Genomic DNA Purification Kit was found significantly higher in terms of isolated DNA concentration (1200-1288 ng.ul-1), yield (257.6 ng.ul-1) and purity (1.91-2.00), and also successful in PCR amplification as compared to other evaluated six traditional DNA isolation methods. The nucleotide minimum bands range was observed 200 base pairs in heart sample and maximum 600 base pair was observed in intestine. There is no data on description of parameters analysed in this work to date, neither the evaluation of isolated DNA using PCR amplification of mitochondrial COI gene for the species N. notopterus. Present study also revealed that the traditional DNA isolation methods are the secondary choice for isolation of DNA. The data of present study also indicated that the GeneJET Genomic DNA Purification Kit is useful for DNA isolation and can be used best in genetic applications for fishes.

The article presents the results of studying the effect of light-emitting diodes (LEDs) on the efficiency of micropropagation of valuable woody plants. Commercial use of micropropagation requires optimization of various parameters, including light quality and lighting regime. Nowadays, LED have become an alternative source of illumination for plant tissue culture, including woody plants. Recently, along with medicinal herbaceous plants, tree crops have also become widely used as a source of various pharmaceuticals. Therefore, it is promising to optimize the technology of micropropagation for the rapid and massive production of valuable woody plants. The current research focused on analysing the effects of different LEDs on Paulownia sp. micropropagation: white (W), red (R), blue (B), mixed red and blue (R:B), and the Fitotron climate chamber. The fluorescent light was used as a control. Micropropagation efficiency was evaluated using the following parameters: height, number of axillary buds, length of internodes, number and length of roots, and photosynthetic pigment content. P. tomentosa produced the greatest number of roots under R LEDs, while hybrid Paulownia Sieb.Zucc. × Elongata - under W and R LEDs. In hybrid Paulownia Sieb.Zucc. × Elongata, the most intense leaf and internode formation was observed under R:B and R LEDs. The content of chlorophyll a and b in P. tomentosa leaves was significantly higher under R LED, while in HP leaves - under B LED. The obtained results are an important contribution to the commercial use of Paulownia and other valuable woody plants for mass production of plant material with biologically active properties.

Over the last few decades, there has been a significant increase in tea consumption worldwide, leading to a growing concern for the quality and nutritional value of tea. The demand for high-quality tea has necessitated the development of new analytical approaches to ensure adherence to quality standards and process control. One area of particular importance is the control of caffeine in tea, as regular consumption of caffeine in large quantities can contribute to the leaching of beneficial minerals from the human body. To address this issue, in this work have developed a rapid technique for determining caffeine in tea samples using miniaturized solid-phase microextraction (mini-SPME) combined with chromatography-mass spectrometry (GC-MS). The study included the screening of teas available in the market of Kazakhstan. In this study optimized the basic parameters of miniaturized solid-phase microextraction of caffeine from tea samples, including fiber coating, extraction temperature, extraction time, and pre-incubation time. The fiber coating used in the study was DVB/CAR/PDMS, and the optimal extraction temperature was found to be 90°C, with an extraction time of 20 minutes and a pre-incubation time of 5 minutes. The developed method is efficient and can be used for determination and control of traces of caffeine in tea samples. Furthermore, the study evaluated the environmental friendliness of the methods for analyzing caffeine in teas using the GAPI tool. The GAPI tool is a software program that assesses the environmental impact of a chemical process by considering several parameters, such as toxicity, energy consumption, and waste generation. The results of the study showed that the developed method was environmentally friendly

Design/methodology/approach: To achieve the research objectives, the study analyzes the financial statements (FRQs) of 74 enterprises listed on the Ho Chi Minh Stock Exchange in Ho Chi Minh City. The data collected in the period from 2019 to 2021, Covid-19 pandemic and analysis by GSEM.
 
Findings: Specifically, the study shows that earnings management exerts a direct negative impact on stock prices. Additionally, it highlights the positive influence of EM on the quality of FRQ information. However, the quality of FRQ news demonstrates a negative effect on stock prices. The study also investigates the role of intermediate variables in the relationship between financial reporting information quality and stock prices.
 
Research, Practical & Social implications: By providing empirical evidence and highlighting the significance of accounting practices in the capital market, the study adds value to academic research, while offering practical insights for investors, regulators, and businesses.
 
Originality/value: By providing empirical evidence and highlighting the significance of accounting practices in the capital market, the study adds value to academic research, while offering practical insights for investors, regulators, and businesses.

Research shows that reading performance in the early grades is a strong predictor of reading ability throughout the school years, and is therefore likely to impact children’s academic and career trajectories, with those of children coming from disadvantaged socio-economic backgrounds being negatively impacted (Cunningham & Stanovich, 1997; Dolean et al., 2019). Using a comparative approach, the present study aimed to determine whether there were differences in literacy skills development in children from low socio-economic backgrounds who received specifically developed emergent literacy instruction (intervention group, IG) and those who did not (control group, CG). The literacy program was developed based on recent scientific evidence (Bear, 2022) emphasizing the importance of the following in emergent literacy instruction: concepts about print (1), alphabet and letter-sound knowledge (2), concept of word (3), phoneme awareness (4), and word recognition (5). The intervention took place in the 2021-2022 school year, over an 8-month period, and consisted of using emergent literacy assessments, as well as literacy learning materials developed specifically for the preparatory grades. The total sample consisted of 300 children in 25 preparatory grade classes, divided between intervention and control groups (260 and 40 students, respectively), who were all assessed on the five abovementioned emergent literacy concepts and skills, pre- and post-intervention. ANOVA analyses were conducted to test for differences between children in the two groups. Results highlight significant differences in terms of literacy development, with children in IG showing higher scores on all the five measures than children in the CG.

Field studies on the cultivation of green cabbage varieties and hybrids using various growth stimulants against the background N120P60K60 were carried out on an irrigated area located at a distance of 1.5 km northwest of the village Solenoe Zaimishche (Astrakhan region) on an irrigated land use area of  FSBNU "Pre-Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences." As a result of the obtained study, the positive effect of leaf treatments during the entire vegetation period was established. Especially the best effect was after joint application of Novosil + N120P60K60 in the hybrid Aggressor F1. At the same time, the yield was 57.5 tons/ha with an increase to the control variant of 15.7 tons/ha.

The relationships between nature, human biology, and the design of the built environment are articulated through the categorization of the 14 biophilic patterns, which are applied in indoor and outdoor environments. They can reduce stress, improve well-being, increase creativity, and direct the user’s attention and clarify of thoughts. Social, culture and economic factors cooperate in the implementation of biophilic projects, using tools aimed at the formulating bibliographic research. In this sense, the objective of the study is to review the concepts of the field of biophilia, defining the patterns that can be applied in the built environment, aiming to propose significant reflections regarding the possible contact of the user with biophilic patterns in affordable housing and design,particularizing in the field of Interior Design.

In the face of global warming, research on carbon removal to mitigate the effects of climate change has been carried out. The use of constructed wetlands for wastewater treatment is known, however the quantity of studies about carbon sequestration of this system is still limited. Thus, the systematic and literature review aimed to expose the characteristics of constructed wetlands in relation to greenhouse gas emissions. The bases used were Scopus, Springer and Google Schoolar and the selected terms were related to constructed wetlands and GHG. It was concluded that the horizontal subsurface flow CWs has the potential to become a carbon sink, due to the carbon retained in the plants, and may emit less N2O than the vertical subsurface flow CW; about the emission of CH4, it is important to know the species of plant adopted due to its influence on methane emissions.

This document is part of a doctoral article defended in 2022, being a theoretical discussion about the Absorptive Capacity and Sustainable Performance of organizations and their relationships. The discussion focuses on questions such as: “which organizational routines allow the acquisition of external green knowledge?” or “which mental models allow the acquisition of green knowledge in organizations”? Does the theoretical discussion propose hypotheses regarding the relationship between: sustainable mental models (MMS) and organizational routines (OR) as drivers of green absorptive capacity and the sustainable performance of organizations?

Published: July 2023

We evaluate the heat pump component of New Zealand’s Warmer Kiwi Homes (WKH) programme. The programme includes provision of heat pumps in living areas for eligible households (based on neighbourhood or income) that do not have such heating. It also includes installation of retrofitted insulation for houses with insufficient insulation. Staggered installation enables difference-in-difference estimates of impacts. Heat pump outcomes on which we focus include warmth and dryness of the living area, personal comfort and wellbeing, and electricity consumption. We combine the heat pump findings with prior findings related to insulation and heating to provide a set of cost benefit analyses of WKH. We find that household members overwhelmingly report increases in warmth, comfort and satisfaction with their home, and report decreases in condensation, damp and having to restrict heating due to cost. Some increase in life satisfaction is reported. Living areas of treated houses experience increases in temperature which are most pronounced around breakfast and evening times, and when outdoor temperatures are low. Houses also experience reduced humidity. Households that use the heat pump as an air conditioner experience reduced summer temperatures when outdoor temperatures are high. Winter electricity use falls in a house fitted with a heat pump relative to houses without a heat pump; savings are negligible at night and increase through the day, peaking at 5-9pm. No increase in electricity consumption is detected in summer. Benefit cost ratios (BCRs) are calculated using both wellbeing metrics and conventional health and energy components. The wellbeing-based BCR for the heat pump component (which places a high value on living in a warm home) is estimated at 7.49 while the more conventionally calculated (but overly conservative) BCR is 2.15. For the full WKH programme, the corresponding BCRs are calculated as 4.36 and 1.89. Complete details of each element of the evaluation are presented in the Full Report available as Motu Working Paper WP 22-14.
