Published: May 2024

Sulfite, a widely used food additive, is subject to regulated labeling. The extraction of sulfite as the stable hydroxymethylsulfonate (HMS) form and its quantitative analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been recognized for their good sensitivity, selectivity, and versatility across various food materials. This study aimed to develop a cost-effective and simpler method for sulfite quantitation, while maintaining the superior sensitivity and selectivity of mass spectrometry (MS). To achieve this, we introduced paper spray ionization (PSI), an ambient desorption ionization technique that could achieve the direct measurement of analytes without employing separation. We also employed a novel internal standard (IS) structurally similar to the analyte, replacing the more expensive isotopically labeled IS. Although the PSI-MS/MS method developed in this study exhibited slightly lower analytical performance compared to the conventional LC-MS/MS, it remained effective for sulfite analysis in dried fruits.

Combretastatins isolated from the Combretum caffrum tree belong to a group of closely related stilbenes. They are colchicine binding site inhibitors which disrupt the polymerization process of microtubules in tubulins, causing mitotic arrest. In vitro and in vivo studies have proven that some combretastatins exhibit antitumor properties, and among them, combretastatin A-4 is the most active mitotic inhibitor. In this study, a series of novel combretastatin A-4 analogs containing carboxylic acid, ester, and amide moieties were synthesized and their cytotoxic activity against six tumor cell lines was determined using sulforhodamine B assay. For the most cytotoxic compounds (8 and 20), further studies were performed. These compounds were shown to induce G0/G1 cell cycle arrest in MDA and A549 cells, in a concentration-dependent manner. Moreover, in vitro tubulin polymerization assays showed that both compounds are tubulin polymerization enhancers. Additionally, computational analysis of the binding modes and binding energies of the compounds with respect to the key human tubulin isotypes was performed. We have obtained a satisfactory correlation of the binding energies with the IC50 values when weighted averages of the binding energies accounting for the abundance of tubulin isotypes in specific cancer cell lines were computed.

Published: May 2024

Every year, new compounds contained in consumer products, such as detergents, paints, products for personal hygiene, and drugs for human and veterinary use, are identified in wastewater and are added to the list of molecules that need monitoring. These compounds are indicated with the term emerging contaminants (or Contaminants of Emerging Concern, CECs) since they are potentially dangerous for the environment and human health. To date, among the most widely used methodologies for the removal of CECs from the aquatic environment, adsorption processes play a role of primary importance, as they have proven to be characterized by high removal efficiency, low operating and management costs, and an absence of undesirable by-products. In this paper, the adsorption of ibuprofen (IBU), a nonsteroidal anti-inflammatory drug widely used for treating inflammation or pain, was performed for the first time using two different types of geopolymer-based materials, i.e., a metakaolin-based (GMK) and an organic–inorganic hybrid (GMK-S) geopolymer. The proposed adsorbing matrices are characterized by a low environmental footprint and have been easily obtained as powders or as highly porous filters by direct foaming operated directly into the adsorption column. Preliminary results demonstrated that these materials can be effectively used for the removal of ibuprofen from contaminated water (showing a concentration decrease of IBU up to about 29% in batch, while an IBU removal percentage of about 90% has been reached in continuous), thus suggesting their potential practical application.
Wind Shear Model Considering Atmospheric Stability to Improve Accuracy of Wind Resource Assessment

Published: May 2024

An accurate wind shear model is an important prerequisite in extrapolating the wind resource from lower heights to the increasing hub height of wind turbines. Based on the 1-year dataset (collected in 2014) consisting of 15-minute intervals collected at heights of 2, 10, 50, 100, and 150 m on an anemometer tower in northern China, the present study focuses on the time-varying relationship between the wind shear coefficient (WSC) and atmospheric stability and proposes a wind shear model considering atmospheric stability. Through the relationship between Monin–Obukhov (M-O) length and gradient Richardson number, the M-O length is directly calculated by wind data, and the WSC is calculated by combining the Panofsky and Dutton (PD) models, which enhances the engineering practicability of the model. Then, the performance of the model is quantified and compared with two alternative methods: the use of annual average WSC and the use of stability change WSC extrapolation. The analysis demonstrates that the proposed model outperforms the other approaches in terms of normal root mean square error (NRMSE) and normal bias (NB). More specifically, this method reduces the NRMSE and NB by 24–29% and 76–95%, respectively. Meanwhile, it reaches the highest extrapolation accuracy under unstable and stable atmospheric conditions. The results are verified using the Weibull distribution.
Study on Early Identification of Rainfall-Induced Accumulation Landslide Hazards in the Three Gorges Reservoir Area
Authors: Wu Zhen , Ye Runqing , Yang Shishi , Wen Tianlong , Huang Jue , Chen Yao
Published: May 2024

The early identification of potential hazards is crucial for landslide early warning and prevention and is a key focus and challenging issue in landslide disaster research. The challenges of traditional investigation and identification methods include identifying potential hazards of landslides triggered by heavy rainfall and mapping areas susceptible to landslides based on rainfall conditions. This article focuses on the problem of early identification of rainfall-induced accumulation landslide hazards and an early identification method is proposed, which is “first identifying the accumulation that is prone to landslides and then determining the associated rainfall conditions”. This method is based on identifying the distribution and thickness of accumulation, analyzing the rainfall conditions that trigger landslides with varying characteristics, and establishing rainfall thresholds for landslides with different accumulation characteristics, ultimately aiming to achieve early identification of accumulation landslide hazards. In this study, we focus on the Zigui section of the Three Gorges Reservoir as study the area, and eight main factors that influence the distribution and thickness of accumulation are extracted from multi-source data, then the relative thickness information extraction model of accumulation is established by using the BP neural network method. The accumulation distribution and relative thickness map of the study area are generated, and the study area is divided into rocky area (less than 1 m), thin (1 to 5 m), medium (5 to 10 m), and thick area (thicker than 10 m) according to accumulation thickness. Rainfall is a significant trigger for landslide hazards. It increases the weight of the sliding mass and decreases the shear strength of soil and rock layers, thus contributing to landslide events. Data on 101 rainfall-induced accumulation landslides in the Three Gorges Reservoir area and rainfall data for the 10 days prior to each landslide event were collected. The critical rainfall thresholds corresponding to a 90% probability of landslide occurrence with different characteristics were determined using the I-D threshold curve method. Prediction maps of accumulation landslide hazards under various rainfall conditions were generated by analyzing the rainfall threshold for landslides in the Three Gorges Reservoir area, serving as a basis for early identification of rainfall-induced accumulation landslides in the region. The research provides a method for the early identification of landslides caused by heavy rainfall, delineating landslide hazards under different rainfall conditions, and providing a basis for scientific responses, work arrangements, and disaster prevention and mitigation of landslides caused by heavy rainfall.
Metadata-Private Resource Allocation in Edge Computing Withstands Semi-Malicious Edge Nodes
Authors: Zhang Zihou , Li Jiangtao , Li Yufeng , He Yuanhang
Published: May 2024

Edge computing provides higher computational power and lower transmission latency by offloading tasks to nearby edge nodes with available computational resources to meet the requirements of time-sensitive tasks and computationally complex tasks. Resource allocation schemes are essential to this process. To allocate resources effectively, it is necessary to attach metadata to a task to indicate what kind of resources are needed and how many computation resources are required. However, these metadata are sensitive and can be exposed to eavesdroppers, which can lead to privacy breaches. In addition, edge nodes are vulnerable to corruption because of their limited cybersecurity defenses. Attackers can easily obtain end-device privacy through unprotected metadata or corrupted edge nodes. To address this problem, we propose a metadata privacy resource allocation scheme that uses searchable encryption to protect metadata privacy and zero-knowledge proofs to resist semi-malicious edge nodes. We have formally proven that our proposed scheme satisfies the required security concepts and experimentally demonstrated the effectiveness of the scheme.

The article presents the results related to minimizing the consequences of risks for agricultural producers. It is established that the credit risk of agricultural enterprises should be considered as the probability of loss not only of mortgaged property, but also of future income. Its components are: systemic risks — arising in the external environment of participants in the credit process; collateral risks — related to the probable loss of mortgaged property or a decrease in its value; production risks — leading to losses in production activities. It is proved that one of the means of reducing credit risks is credit insurance, which should be considered as a set of types of insurance aimed at reducing credit risk at the level of the borrower and the lender. At the level of an agricultural enterprise, crop insurance, animal insurance, life insurance of the borrower, liability insurance for non-repayment of loans can be used. At the lender level, such insurance concerns the risk of non-repayment of loans and the risk of loss of property by the mortgagee. It was found out that a number of risks that lead to high loss-making of agricultural enterprises have a significant impact on the process of crediting agricultural enterprises. In particular, the combination of systemic risks, most of all price, inflation, and government regulation risk, reinforced by the complexity of the formation of market structures, leads to price disparity between products produced in agriculture and products consumed by them. It is determined that agricultural enterprises are not able to generate stable cash receipts, and the lack of an effective mechanism for the sale of agricultural products also does not contribute to increasing the profitability of enterprises in the industry.

A method of sound source recognition based on two stagewise weak orthogonal matching pursuit
Authors: Mao Jin , Zhao Weipeng , Liu Kai , Chen Yuxi , Fan Xingyu
Published: May 2024

The stagewise weak orthogonal matching pursuit (SWOMP) algorithm solves the problem that the orthogonal matching pursuit (OMP) algorithm relies too much on the sparsity of sound sources in the process of sound source identification. However, compared with OMP algorithm, SWOMP algorithm
has some disadvantages, such as lower spatial resolution and worse identification accuracy. To solve the problem of poor reconstruction effect of SWOMP algorithm, a sound source identification algorithm based on two stagewise weak orthogonal matching pursuit (TSWOMP) is proposed. In this method,
the initial atom set is obtained by threshold selection, the reliability of the primary atom set is detected, and the wrong atoms in the primary atom set are further deleted. Finally, the position and size of the sound source signal are identified according to the obtained final atom set.
Under different frequencies and signal-to-noise ratios, the simulation results show that compared with SWOMP algorithm, TSWOMP algorithm can effectively reduce the main lobe width, suppress the influence of side lobes and significantly improve the spatial resolution. Moreover, even if the
sparsity of sound source is unknown, it can achieve the same recognition accuracy as OMP algorithm and has high recognition stability. Finally, the validity and reliability of TSWOMP algorithm are further verified by experiments.
The effect of non-removable void generators on the strength of monolithic reinforced concrete floor slabs clamped along the contour
Authors: Dzhamuev B. K.
Published: May 2024

The article presents the results of a numerical experiment to determine the effect of non-removable void generators on the strength of monolithic reinforced concrete floor slabs clamped along the contour. The experimental samples are made in the form of spatial models using volumetric finite element models in the LIRA-CAD software package. The tests were carried out on 4 series of samples, differing in terms of dimensions and reinforcement. Detailed descriptions of the dependencies used and the laws of deformation of materials during the construction of models are given. The values of compressive stresses in concrete and reinforcement, as well as tensile stresses in reinforcement obtained as a result of tests, were subjected to comparative analysis. Based on the conducted experiment, it was found that the use of non-removable voids in a monolithic reinforced concrete slab does not reduce its strength, while reducing concrete consumption by 18.3-23.1%.
Architectural and artistic solutions of the OTC during the gentrification of soviet cinemas
Authors: Mikhaylova E. V.
Published: May 2024

In the professional environment of architects, there is concern about the formation of a trend of reconstruction and renovation of buildings and structures in large and major cities in order to develop urban infrastructure. The underestimation of the contribution of Soviet architecture to the cultural heritage of post-Soviet countries and countries of the socialist camp is noted. At the same time, the "new architecture" forms the urban environment under the stereotypes of homologation, which does not correspond to the socio-cultural demand of the glocalization of "digital nomads" seeking to live in eco-digital cities. The obsolescence of the "new architecture" is observed already at the project stage or in five years. In Moscow, the reconstruction program includes 39 Soviet cinemas in the peripheral zone of the city. Public and shopping complexes with underground levels are being built on the site of these cinemas. The article classifies the types of projects of Soviet cinemas and shopping centers, and also forms diagrams for their qualitative comparison. This eventually made it possible to evaluate the architectural and artistic contribution to the Moscow development of both Soviet cinemas and new shopping complexes, the continuity between them and differences in design principles.
Occupational therapists in Aotearoa responding to community need
Authors:   , Hannah Grace
Published: May 2024

Within occupational therapy, there is an increasing focus on integrating healthcare and community development practices to address issues of marginalisation and social injustice. Occupational therapists recognise their potential contribution to areas of community practice, utilising their occupational perspective to address contextual barriers facing communities, and enhancing opportunities for occupational engagement. The primary aim of this research was to explore how Aotearoa-based occupational therapists respond to the occupational needs of communities and integrate their occupational perspective while working alongside communities. Utilising an interpretive descriptive methodology, interviews were carried out with five participants from a range of locations and communities throughout Aotearoa. Participants were asked to reflect on how their professional background informed the ways they work alongside their respective communities, factors that supported and challenged their practice, and their hopes for the future of community practices. Participating therapists described working with a diverse range of communities, but uniformly identified the ‘doing’ perspective as the unique contribution they made as occupational therapists working in these roles. Participants emphasised how the occupational perspective grounded their professional identity, and enabled them to identify and respond to the different occupational needs present within their communities. The findings revealed that therapists practising in community-responsive roles undergo a process of ‘being,’ ‘becoming,’ and ‘belonging.’ These roles challenge established ideas of what it means to ‘be’ an occupational therapist, and present a range of supports and challenges while ‘becoming’ a therapist who works with communities. Additionally, therapists must navigate where they ‘belong’ within the occupational therapy profession and broader social context. This research has demonstrated how occupational therapists apply their ‘doing’ perspective to empower communities and increase opportunities for participation. It has also shown that validation and support from the occupational therapy profession are essential for these therapists to feel confident and enthusiastic about their unique contributions with Aotearoa communities. Recommendations from this research include raising awareness of community practices, engaging in critical reflection on underlying discourses informing occupational therapy practice and professional identity, and promotion of cultural safety and recognition of te ao Māori. It is hoped that these recommendations will support the development of community-responsive roles within Aotearoa.

The work considered the influence of the main parameters of the arc surfacing in protective gases with electrode transverse oscillations on the formation of low-carbon low-alloy deposited metal. It has been defined that the range of deposited beads defect-free formation modes is quite narrow and exists in the region of high values of welding current, low values of welding rate and electrode oscillation frequency. It is shown that the heat input increase of surfacing with the constant amplitude and frequency of oscillations allows not only to improve the formation of the weld bead, but also to obtain the smoother gradient of changes properties along the height of the multilayer deposited metal and at the heat-affected zone of the base metal.

Authors: Koffi DJIWONOU , Bi Tra Jean NANTI
Published: May 2024

Cuttings are a vegetative propagation technique used by small farmers to improve crop yield and income. It promotes the conservation of the genetic heritage of plants. This study investigated the influence of shelter on sprouting and seedling growth of the Lompung cultivar of pepper (Piper nigrum L.) in nursery. This plant characterized by large leaves has been used for the production of tunnel and nursery shelter seedlings. The tests were conducted for three months (November 2016 - January 2017). The device used was a completely random block. The parameters studied included the timing and germination rate of the cuttings, the number of leaves, the leaf area, the length and the dry root biomass of the plants. ANOVA 1 and the Ducan test were used to analyze the results obtained. Statistical analysis of the data showed that the performance of the plants obtained under tunnels was higher than that of plants grown under nursery shelter. These include collet diameter, number of leaves and leaf area, length, and root biomass. On the other hand, the germination time was not influenced by the cropping systems. This study has shown that cuttings of pepper tunnels are favorable to vegetative multiplication.

REAL-TIME WHEAT DETECTION BASED ON LIGHTWEIGHT DEEP LEARNING NETWORK REPYOLO MODEL
Authors: BI Zhifang , LI Yanwen , GUAN Jiaxiong , ZHANG Xiaoying
Published: May 2024

Real-time detection has become an essential component in intelligent agriculture and industry. In this paper, a real-time wheat spike detection method based on the lightweight deep learning network RepYOLO is proposed. Addressing the small and densely packed phenotype characteristics of wheat spikes, the channel attention mechanism module CBAM from the traditional YOLOv4 algorithm is introduced and multiple convolutional kernels are merged using a structural reparameterization method. Additionally, the ATSS algorithm is incorporated to enhance the accuracy of object detection. These approaches significantly reduce the model size, improve the inference speed, and lower the memory access cost. To validate the effectiveness of the model, it is trained and tested on a large dataset of diverse wheat spike images representing various phenotypes. The experimental results demonstrate that the RepYOLO algorithm achieves an average accuracy of 98.42% with a detection speed of 8.2 FPS. On the Jetson Nano platform, the inference speed reaches 34.20 ms. Consequently, the proposed model effectively reduces the memory access cost of deep learning networks without compromising accuracy and successfully improves the utilization of CPU/MCU limited performance.

Authors: KANG Shilei , HE Junlin , WANG Tao
Published: May 2024

In this study, a central unloading reel structure was proposed to achieve continuous harvest of Cerasus humilis, and an indoor test bench was constructed to carry out the combing test of branches. The cross-section of the comb was made of an isosceles triangle, and an orthogonal test was carried out with tooth gap, winch rotational velocity and cross-section base angle as test factors, and fruit breakage rate and leakage rate as test indicators. The results show that the tooth gap and winch rotational velocity have a significant influence on the breakage rate, and the tooth gap and section bottom angle have a significant influence on the fruit leakage rate. Considering the comprehensive loss rate, the appropriate deformation of the comb teeth and the manufacturing difficulty, the optimal values of the three test factors are 10 mm, 130 r/min, and 45°, respectively. At the same time, the maximum combing force of a single branch through the comb is 240 N through the pressure sensor of the test bench. The experimental results can be used as the basis for the structural design of continuous harvesting head.

Published: May 2024

Vibratory harvesting is to dislodge fruits by applying excitation force to fruit trees, so the vibration response characteristics of fruit trees are of great significance for vibratory forest and fruit harvesting machinery to realize efficient harvesting. The effects of different clamping points and vibration frequencies on vibration responsiveness and energy transfer in Broussonetia papyrifera branches are investigated in this study. The results show that the effects of different clamping point positions and vibration frequencies on the branch vibration response are mutual. The ideal distance between the clamping point position and the base of the main branch should be between 48% and 73% of the branch length, and the distance between the clamping point position and the base of the main branch increased with the increase of vibration frequency. This is because, when the clamping point is close to the base of the main branch, a higher excitation frequency increases the energy consumption at the base of the main branch, and the amount of ineffective vibration energy transferred to the base of the main branch also increases. Therefore, when the location of the clamping point is close to the base of the main branch, the suppression of high-frequency vibration at the base of the main branch is stronger than the suppression of low-frequency vibration. When the clamping point is located in the center of the branch, the overall response of the branch to vibration is better.

EXCHANGE RATE PASS-THROUGH TO IMPORT AND CONSUMER PRICES IN NIGERIA
Authors: Hamzat Aisha T. , Oye Queen Esther , Deji Kujembola T.
Published: May 2024

This study investigates exchange rate pass-through (ERPT) to import and consumer prices in Nigeria. The literature about the influence of ERPT on inflation in Nigeria did not consider the initial transmission stage because it primarily focused on the influence exchange rate fluctuations had on consumer prices, while neglecting the influence on import prices. In addition, a good proxy for measuring import prices has not been used, which could facilitate a more comprehensive analysis of the study area. Therefore, this study contributes to knowledge by examining the initial transmission stage of the exchange rate pass through (ERPT) before it passes through consumer prices. The goals of this study were to determine the degree of ERPT to import and consumer prices in Nigeria and examine the discrepancy in the response of import and consumer prices to positive and negative shocks of the exchange rate in Nigeria. The analysis relied on quarterly time series data obtained from the World Development Indicators (WDI) and the Central Bank of Nigeria (CBN), covering the time frame from 2000 Q1 to 2021 Q4. It explains ERPT to import and consumer prices using the CBN Statistical Bulletin’s Import Price Index as a suitable proxy for import prices in Nigeria. It uses autoregressive distributed lag (ARDL) and nonlinear ARDL (NARDL) techniques to estimate the ERPT and its influence on consumer and import prices. The research finds an asymmetric and incomplete ERPT to Nigerian import and consumer prices. Additionally, the analysis reveals a direct association between appreciation in the exchange rate and increases in consumer and import prices. The import price of the previous quarter significantly impacts inflation in Nigeria. It also finds an inverse relationship between GDP and inflation, with GDP having a greater impact on consumer prices than the exchange rate in Nigeria. As a result, the research suggests that it would be advantageous for the government to prioritize the implementation of policies that diminish dependence on imported goods. In addition, it recommends that the government give precedence to implementing measures that promote economic expansion.

Authors: Amelia Vera , Sinaga Soaloon , Risma Rinda W. , Bhermana Andy
Published: May 2024

The existence of land resources should be assessed to provide appropriate land use and management information, especially for agricultural development. The Pulang Pisau district has wetlands dominated by swampland areas that have potential for farming activities; therefore, it is important to develop a spatial concept as a basic area development for the future. The study provided a spatial concept based on land resource evaluation for paddy field development. In this study, the methods of land suitability evaluation and geographic information system (GIS) application were utilized as the tools for analysis. The information obtained from this study can be used as basic consideration in land use planning for agriculture in general. The findings indicate that the land suitability classification for paddy fields in wetlands is marginally suitable. The total area of wetlands assessed is 393,419 hectares, with 60.78% (239,112 hectares) consisting of mineral soils and 39.22% (154,307 hectares) consisting of organic soils. The farming technology specific to location can then be implemented to optimize land management to develop paddy fields in the wetlands of Pulang Pisau district. The extensification program can be targeted toward available areas, while intensification programs can focus on developing paddy fields in existing farming areas using location-specific technology.

Decyzję o powierzeniu mi tej zaszczytnej i odpowiedzialnej roli przyjąłem z wielką radością i poczuciem głębokiej satysfakcji. Mam przy tym świadomość, że kierowanie czasopismem o prestiżowym i ugruntowanym w świecie akademickim tytule świadczy o ogromnym zaufaniu, jakim zostałem obdarzony. Wszystkim członkom Rady Instytutu bardzo dziękuję za oddany na mnie głos i zapewniam, że zrobię wszystko, aby kontynuować piękną tradycję czasopisma, które przez niespełna piętnaście lat swojego istnienia wniosło niebagatelny wkład przede wszystkim do nauk o kulturze i religii, ale także do innych dyscyplin nauk humanistycznych, m.in. historii, literaturo­znawstwa, polonistyki, sztuki czy antropologii kulturowej.

Authors: Świerczyńska-Głownia Weronika , Wójcik Magdalena
Published: May 2024

Przedmiot artykułu stanowią strategie doboru źródeł osobowych przez dziennikarzy. Celem jest określenie różnic w sposobach i kryteriach doboru osób reprezentujących tzw. autorytety poznawcze i ekspertów w świetle teorii P. Wilsona. Przeprowadzono badania opierające się na kwestionariuszu ankiety na grupie dziennikarzy związanych z obszarem kultury zatrudnionych w redakcjach radiowych, telewizyjnych oraz serwisach internetowych. W rezultacie przeprowadzonych badań określono ścieżki doboru autorytetów poznawczych i ekspertów na użytek pracy dziennikarskiej oraz wystosowano propozycję udoskonalenia tych procesów.
The Partial Nature of Metaphorical Mappings(2) -Structural Metaphor Focusing on the metaphorical utilization of death-
Authors:   Urimal Society, Bai Do-Yong
Published: May 2024

The purpose of this study is to examine the partiality of metaphorical utilization in the thought of the conceptual metaphor 'death'. Applying the proposed multifaceted cognitive model (MCM) for this purpose, the results are as follows. First, in terms of the frequency of occurrence of the elements of the MCM, the source aspect in which both single and multiple actions occurred was more diverse than the goal aspect, death, and they were generally in the order of 'goal aspect> shape aspect> action aspect>material aspect'. Second, in terms of the subject's agentic power, we could distinguish between active (12.5%) and passive (87.5%) attitudes, which was consistent with the subject's loss of control in the goal aspect. This allowed us to infer that death is being controlled by the subject's passive attitude rather than being controlled by the subject's active attitude. Third, the identification of the partiality of metaphorical utilization ultimately led to a broader understanding of the target domain of death.

The Diversity Argument for Affirmative Action in Medical School: A Critique
Authors: Kershnar Stephen
Published: May 2024

In this article, I argue that medical school admissions should be limited to statistically relevant factors. I argue for it based on two other conclusions: a medical school should maximize quality-adjusted medical services per graduate within the overall optimum spending limit and if this is correct, then a medical school should, other things being equal, select medical students who are better than their competitors. I then explore the implications of this argument for whether a medical school admissions system should be holistic and whether it should consider demographic factors. I also consider and respond to a series of objections to the argument.
L’analisi pedagogica come oggetto. Spunti di riflessione della comunità scientifica fra teoria e prassi
Authors: Ferrari Monica
Published: May 2024

The essay discusses the reasons behind the decision to hold a conference at the Collegio Ghisleri, Pavia, on 27 May 2023 and to publish in this journal the dossier that originated from this event, which was an occasion for exchange and discussion. The underlying idea was to gather together representatives (Presidents or their delegates) of national and international scientific societies, especially Italian and French, as well as researchers from different European countries (especially Italy, France and Germany) and from different scientific-disciplinary fields in order to put pedagogical analysis at the center of the debate as a subject of study, along with its impossible and hypercomplex objects, which are the result of constant transactions that necessarily take us beyond the institutional scientific-disciplinary boundaries. A problematization of the epistemic territory between theory and practice thus emerges, also starting from the dossier’s red threads and key themes.
Sistemi educativi, orientamento, lavoro. Nuove generazioni e ricerca pedagogica
Authors: Malavasi Pierluigi
Published: May 2024

Educational systems, orientation and work designate closely interconnected universes of discourse and practices. There is no inclusive and quality work where there are neither quality training nor orientation. Supply and demand in the workplace risk not matching where an educational, systemic culture of orientation and scientific work is lacking. This is, however, necessary to build young generations of pedagogists imbued with trust, rigor and orientation towards the future, with humility and initiative.
Una ricerca senza oggetti per rimuovere limiti e aprire possibilità
Authors: Lucisano Pietro
Published: May 2024

The text reflects on the risk that the research of one’s object of study by scientific societies turns into the definition of disciplinary boundaries. In this sense, the search for identity through the definition of the objects of study reproposes the largely outdated subject-object paradigm on the one hand, while on the other it engages the conflicts with those who work on the same themes. Furthermore, recognizing oneself by agreeing on the objects of research distracts pedagogical societies from considering the real impact of one’s research, while the problem is not so much recognizing oneself within societies as it is being recognized and having a real impact on educational systems.
La formazione fra creatività ed emergenze
Authors: Gramigna Anita
Published: May 2024

The following considerations give an account of the discussion which took place within the board of the SIREF, in the light of the intellectual and spiritual legacy that Professor Umberto Margiotta left us. And it is on this basis that we acknowledged the great thematic context of Meta-cognition as central, both in pedagogical analysis and in educational practices in general. This, in turn, brings to our attention, as an epistemic consequence, the issue of methodology, postulated in its quality as normative epistemology. It is, evidently, a theoretical-methodological scenario that mirrors its heuristics on Education, which today, more than ever, requires us to face its difficult emergencies with renewed creativity. It is precisely around the issue of creativity that we have identified the imaginary as an educational field of study. The imaginary intercepts all the challenges of the contemporary world: its dramatic drifts as well as its magnificent opportunities. All of this takes place in the light of an epistemological diaphanization of the instances of the contemporary and of its guidelines, and then of a metacognitive proposal.
La Società Italiana di Educazione Motoria e Sportiva: neurodidattica e ricerca nelle scienze motorie
Authors: Casolo Francesco
Published: May 2024

The SIEMeS (Società Italiana di Educazione Motoria e Sportiva) is a pedagogical scientific society born in 2015. The purpose of the Society is to promote, coordinate and encourage scientific research in the field of physical and sport education, with special regard to the development and teaching of theories, techniques and methodologies for physical and sport education. The most important field of research developed by the SIEMeS concerns the neurodidactics of motor activities, which represents a well-defined and promising area within physical training and sport sciences; nowadays, neurodidactics allows us to use scientific evidences regarding the functioning of the brain in order to optimize the traditional teaching-learning process. The main areas of research developed by the scientific Society concern: embodied and situational learning, motor activities and enjoyment, the role of information technologies in teaching, new perspectives for the development of open skills oriented towards self-efficacy and self-esteem, and the use of practice variability in teaching.
