A 3D Reconstruction Framework of Buildings Using Single Off-Nadir Satellite Image
Authors: Zhao Chunhui , Zhang Chi , Yan Yiming , Su Nan
Published: November 2021

A novel framework for 3D reconstruction of buildings based on a single off-nadir satellite image is proposed in this paper. Compared with the traditional methods of reconstruction using multiple images in remote sensing, recovering 3D information that utilizes the single image can reduce the demands of reconstruction tasks from the perspective of input data. It solves the problem that multiple images suitable for traditional reconstruction methods cannot be acquired in some regions, where remote sensing resources are scarce. However, it is difficult to reconstruct a 3D model containing a complete shape and accurate scale from a single image. The geometric constraints are not sufficient as the view-angle, size of buildings, and spatial resolution of images are different among remote sensing images. To solve this problem, the reconstruction framework proposed consists of two convolutional neural networks: Scale-Occupancy-Network (Scale-ONet) and model scale optimization network (Optim-Net). Through reconstruction using the single off-nadir satellite image, Scale-Onet can generate water-tight mesh models with the exact shape and rough scale of buildings. Meanwhile, the Optim-Net can reduce the error of scale for these mesh models. Finally, the complete reconstructed scene is recovered by Model-Image matching. Profiting from well-designed networks, our framework has good robustness for different input images, with different view-angle, size of buildings, and spatial resolution. Experimental results show that an ideal reconstruction accuracy can be obtained both on the model shape and scale of buildings.
A Preliminary Assessment of a Newly-Defined Multispectral Hue Space for Retrieving River Depth with Optical Imagery and In Situ Calibration Data
Authors: Le Moine Nicolas , Mahdade Mounir
Published: November 2021

Bathymetry is a key element in the modeling of river systems for flood mapping, geomorphology, or stream habitat characterization. Standard practices rely on the interpolation of in situ depth measurements obtained with differential GPS or total station surveys, while more advanced techniques involve bathymetric LiDAR or acoustic soundings. However, these high-resolution active techniques are not so easily applied over large areas. Alternative methods using passive optical imagery present an interesting trade-off: they rely on the fact that wavelengths composing solar radiation are not attenuated at the same rates in water. Under certain assumptions, the logarithm of the ratio of radiances in two spectral bands is linearly correlated with depth. In this study, we go beyond these ratio methods in defining a multispectral hue that retains all spectral information. Given n coregistered bands, this spectral invariant lies on the (n−2)-sphere embedded in Rn−1, denoted Sn−2 and tagged ‘hue hypersphere’. It can be seen as a generalization of the RGB ‘color wheel’ (S1) in higher dimensions. We use this mapping to identify a hue-depth relation in a 35 km reach of the Garonne River, using high resolution (0.50 m) airborne imagery in four bands and data from 120 surveyed cross-sections. The distribution of multispectral hue over river pixels is modeled as a mixture of two components: one component represents the distribution of substrate hue, while the other represents the distribution of ‘deep water’ hue; parameters are fitted such that membership probability for the ‘deep’ component correlates with depth.

Published: November 2021

We conducted a systematic review and inventory of recent research achievements related to spaceborne and aerial Earth Observation (EO) data-driven monitoring in support of soil-related strategic goals for a three-year period (2019–2021). Scaling, resolution, data characteristics, and modelling approaches were summarized, after reviewing 46 peer-reviewed articles in international journals. Inherent limitations associated with an EO-based soil mapping approach that hinder its wider adoption were recognized and divided into four categories: (i) area covered and data to be shared; (ii) thresholds for bare soil detection; (iii) soil surface conditions; and (iv) infrastructure capabilities. Accordingly, we tried to redefine the meaning of what is expected in the next years for EO data-driven topsoil monitoring by performing a thorough analysis driven by the upcoming technological waves. The review concludes that the best practices for the advancement of an EO data-driven soil mapping include: (i) a further leverage of recent artificial intelligence techniques to achieve the desired representativeness and reliability; (ii) a continued effort to share harmonized labelled datasets; (iii) data fusion with in situ sensing systems; (iv) a continued effort to overcome the current limitations in terms of sensor resolution and processing limitations of this wealth of EO data; and (v) political and administrative issues (e.g., funding, sustainability). This paper may help to pave the way for further interdisciplinary research and multi-actor coordination activities and to generate EO-based benefits for policy and economy.
Resurgence, Populism, and Politics ‘From Below’
Authors: Cherry Keith
Published: November 2021

Populist politics are an increasingly prominent feature of contemporary politics around the world. In settler colonies, Indigenous resurgence is also an increasingly important feature of political contestation. Both discourses involve questions of peoplehood, pluralism, and collective agency. The goal of this paper is to explore these phenomena side by side, and ask what they reveal about the present political conjuncture. I argue that both political projects involve a constructive element, as actors build spaces of political contestation beyond the state. In this way, each movement involves an often overlooked contest between politics ‘from above’ and ‘from below’. Ultimately, I conclude that the above/below distinction reveals important cleavages that are obscured by the traditional left/right distinction that structures much political analysis.
A New Product Development Model for SMEs: Introducing Agility to the Plan-Driven Concurrent Product Development Approach
Authors: Žužek Tena , Gosar Žiga , Kušar Janez , Berlec Tomaž
Published: November 2021

In order to survive in today’s highly competitive global market, small and medium-sized enterprises (SMEs) have had to transition from sequential to concurrent product development, which significantly shortens development cycles, reduces costs, and ensures high product quality. Despite its many benefits, concurrent product development is still based on detailed upfront planning and cannot address the challenges related to today’s ever-growing uncertainty, constantly changing environment, and unstable requirements. A potential solution to this problem could be in more flexible and value-driven agile project management (APM) approaches, typical of software development. In this paper, we propose a new product development model specifically appropriate for SMEs that combines concurrent product development principles with APM elements. It is designed as a loop of five repetitive steps (macroplan, microplan, iteration activities, review, and retrospective) that are being executed within individual concurrent development loops. The application of the model is presented on a real case example of process development and small batch manufacture of a complex wiring harness. The study reveals many benefits of the proposed model, such as improved communication, faster detection of discrepancies, more effective problem solving, and greater flexibility. A positive impact on project success is also observed.
And Then There Was COVID-19: Do the Benefits of Cooperative Learning Disappear When Switching to Online Education?
Authors: Blondeel Eva , Everaert Patricia , Opdecam Evelien
Published: November 2021

In the spring of 2020, the COVID-19 pandemic induced a rapid shift to online education. University instructors promptly reinvented their teaching methods and developed digital lessons. Cooperative learning has been demonstrated to surpass lecture-based learning (LBL) regarding students’ learning processes; therefore, the question arises as to whether the perks of cooperative learning still hold when switching to online education. This study examines whether the benefits of team-based learning (TBL) regarding good teaching (i.e., perceived teaching quality), satisfaction, and performance persist when switching from face-to-face to online education. A quasi-experiment in an undergraduate advanced accounting course compared a non-COVID-19-affected semester to a COVID-19-affected semester. In both semesters, students could choose between a TBL and a LBL path for tutorial sessions. Quantitative survey data (N = 455) indicate TBL outperforms LBL, even when switching to online tools. Good teaching was perceived as even better in the COVID-19-affected semester, and even more so by students in the team-based setting, compared to the lecture-based setting. Students’ course satisfaction and performance were unaffected by the switch to online education. This paper shows that TBL still benefits students, even in a blended environment.
Voluntary Work in Digital Contexts as Gift Exchange
Authors: Ruiner Caroline
Published: November 2021

Digital technologies have inspired a change in volunteering in nonprofit organizations. In this context, the engagement of volunteers is mainly self-organized, through online platforms or apps. It is the aim of this paper to analyze the volunteers’ motives, differentiating between self-interest and other-interest. This is important, since effects on organizational volunteer-related outcomes, such as volunteer engagement, recruitment and retention, are likely to occur. A gift exchange perspective is applied and a case study has been used for investigating an online-based nonprofit organization in Germany, consisting of qualitative interviews with experts and volunteers, documentary analysis and participatory observations as well as an online survey. The results show that the volunteers’ instrumental self-interest in gaining food, and their interests in other factors, such as the reduction of food wastage as a societal goal, occur simultaneously. This leads to paradoxes and problems on the organizational level. This study contributes to understanding volunteer engagement, recruitment and retention in digital nonprofit organizations.
Exploring Public Recognition and Perceived Cultural Value of the Special Qualities within English Areas of Outstanding Natural Beauty
Authors: King Isabelle , Martin John
Published: November 2021

As both the concept of ‘landscape’ and ‘beauty’ have very perceptual definitions, they must be assessed by large groups to be appropriately addressed. Therefore, amid a review of AONB designation, cultural perceptions of what is valuable within these designated areas is of paramount importance. Ecosystem services have gained traction as a way to assign social value to the non-physical benefits landscape can provide. AONB landscapes have a list of ‘special qualities’ (SQs) which are the features and characteristics of this area that warrant its protection. This study looks at the extent to which SQs reflect public values. Multiple methods including photo elicitation, participatory mapping, in-person surveys and social media data analysis have been used. The study suggests that when presented with the same landscape there is huge diversity as to what should be considered ‘special’. There is a general preference of landscape heterogeneity, therefore no one SQ could be more important than any of the others if considered in isolation. SQs that have a tangible link to the cultural ecosystem services they provide, were most appreciated. All methods used had their own benefits and flaws, hence future research should use a combination of methods to address perception issues.
Experimental Study of the Fatigue Performance of the Bonding Surfaces and Load-Bearing Capacity of a Large-Scale Severely Damaged Hollow Slab Strengthened by CFRP
Authors: Hu Hao , Dong Chuan-Zhi , Wang Jiji , Chen Jiaqi
Published: November 2021

In recent years, carbon fiber reinforced polymer (CFRP) has been widely used in bridge repair, retrofitting, rehabilitation and strengthening to improve the bearing capacity. Although many studies have been conducted to explore the strengthening efficiencies of CFRP, the test specimens were small and the results were difficult to apply to full-scale bridges. Investigations into the strengthening effects of CFRP on real life structures rely on field load tests (without damaging the structures), making it difficult to understand actual improvements in load carrying capacity and strengthening effect. Moreover, there have been few experimental studies on the fatigue performances of CFRP-strengthened structures, especially on the large-scale structures with real wheel moving loads. In this study, the feasibility and efficiency of CFRP strengthening and repair was investigated on a large-scale, prestressed concrete hollow slab decommissioned from a real-life concrete bridge. The hollow slab was first put through a destructive test to test the ultimate load-bearing capacity. Then, CFRP strips were installed on the surface of the severely damaged slab to repair and strengthen it. Fatigue load test—including the moving load test and single point sinusoidal load—and load-bearing capacity tests were conducted on the CFRP-strengthened hollow slab after the destructive test to evaluate the strengthening performance. This study could help us to understand the actual load-bearing capacities of severe damaged concrete structures strengthened by CFRP, reduce waste, save resources and improve the utilization of our infrastructures.

Authors: Amentae Tadesse Kenea , Gebresenbet Girma
Published: November 2021

Achieving transition towards sustainable and resilient food systems is a critical issue on the current societal agenda. This study examined the potential contribution of digitalization of the food system to such transition by reviewing 76 relevant journal articles, indexed on the Scopus database, using the integrative literature review approach and descriptive content analysis with MAXQDA 2020 software. ‘Blockchain’ was the top hit among keywords and main concepts applied to the food system. The UK as a country and Europe as a continent were found to lead the scientific research on food system digitalization. Use of digital technologies such as blockchain, the Internet of Things, big-data analytics, artificial intelligence, and related information and communications technologies were identified as enablers. Traceability, sustainability, resilience to crises such as the COVID-19 pandemic, and reducing food waste were among the key benefit areas associated with digitalization for different food commodities. Challenges to practical applications related to infrastructure and cost, knowledge and skill, law and regulations, the nature of the technologies, and the nature of the food system were identified. Developing policies and regulations, supporting infrastructure development, and educating and training people could facilitate fuller digitalization of the food system.

Published: November 2021

University students are expected to have the appropriate digital competence to face the demands of the changing educational model and to meet the challenges of the future work. This paper describes university students’ perceptions of digital competence and analyzes the impact of personal factors on digital competence in a sample of 5164 students from all majors in the first and fourth year of their studies at Gansu Agricultural University (China). A quantitative methodology was followed, employing a non-experimental method and the survey technique to collect data. The results obtained show that students’ perceptions of digital competencies in terms of information and data literacy, communication and collaboration, and safety were positive. Furthermore, there were significant differences in students’ self-perceptions of digital competence related to gender, grade level, area of residence, and prior relevant training in the DigComp framework-based instrument. The development of key competency areas for digital competence, such as the creation of digital content, should be promoted, along with helping students to gain knowledge when dealing with everyday technological issues. The need for training related to the use of ICT and digital competencies was also highlighted, as well as supporting the promotion of female students in selected areas of digital competence and assisting lower grade students and students from rural areas in digital competence development.
Ecotourism as a Forest Conservation Tool: An NDVI Analysis of the Sitakunda Botanical Garden and Ecopark in Chattogram, Bangladesh

Published: November 2021

Ecotourism, a sustainable form of tourism, is increasingly being viewed as a tool that can promote global biodiversity and forest conservation. This study explored the scope of ecotourism in forest conservation practices in the developing context by taking the Sitakunda Botanical Garden and Ecopark (SBGE), Bangladesh’s first ecopark established in 2000, as a case study. Using GIS and remote sensing technology, NDVI analysis revealed that, unlike the anticipated outcomes of the SBGE project, after a brief increase in vegetation coverage of 84.6% from 1995 to 2000, the vegetation coverage fell drastically from 2000 to 2015, wherein 33.4% of vegetation had been completely removed, and much of the dense and medium vegetation had been converted to sparse vegetation or other land uses. Anthropogenic activities, namely, unplanned urbanization, are suggested as the major contributors to this decline. From the period of 2015 to 2020, however, vegetation was seen to regenerate, potentially due to the decelerating urbanization or the possible manifestation of the ‘U’ shape relationship between the changes in vegetation and rates of urbanization. Sustainable land-use policies may help attain the targets of the project and lead the SBGE to emerge as a success story of the Bangladeshi ecotourism industry.

Using wastewater accumulating around rural waterpoints to irrigate community gardens, borehole-garden permaculture (BGP) presents a method of sustainable water management. BGP also presents public health benefits through the removal of stagnant water around boreholes, key Malaria breeding grounds, and through providing year-round food to supplement diets. By analysing a dataset of over 100,000 cases, this research examines the awareness and adoption of BGP across Malawi. Generalised linear models identified significant variables influencing BGP awareness and uptake revealing that socioeconomic, biophysical and waterpoint-specific variables influenced both the awareness and adoption of BGP. BGP had low uptake in Malawi with only 2.4% of communities surveyed practising BGP while 43.0% of communities were aware of BGP. Communities in areas with unreliable rainfall and high malaria susceptibility had low BGP awareness despite BGP being particularly beneficial to these communities. This work suggests that future work in the promotion of BGP should focus their efforts within these areas. Furthermore, this work highlights the value of community networks in knowledge sharing and suggests that such social capital could be further used by NGOs and the Government of Malawi in the promotion of BGP and other sustainable practices.
The Application of Mixed Smoothing Spline and Fourier Series Model in Nonparametric Regression

Published: November 2021

In daily life, mixed data patterns are often found, namely, those that change at a certain sub-interval or that follow a repeating pattern in a certain trend. To handle this kind of data, a mixed estimator of a Smoothing Spline and a Fourier Series has been developed. This paper describes a simulation study of the estimator in nonparametric regression and its implementation in the case of poor households. The minimum Generalized Cross Validation (GCV) was used in order to select the best model. The simulation study used generation data with a Uniform distribution and a random error with a symmetrical Normal distribution. The result of the simulation study shows that the larger the sample size n, the better the mixed estimator as a model of nonparametric regression for all variances. The smaller the variance, the better the model for all combinations of samples n. Very poor households are characterized predominantly in their consumption of carbohydrates compared to that of fat and protein. The results of this study suggest that the distribution of assistance to poor households is not the same, because in certain groups there are poor households that consume higher carbohydrates, and some households may consume higher fats.
Monitoring Potentially Toxic Element Pollution in Three Wheat-Grown Areas with a Long History of Industrial Activity and Assessment of Their Effect on Human Health in Central Greece
Authors: Thalassinos Georgios , Antoniadis Vasileios
Published: November 2021

Agricultural lands, especially those where wheat is cultivated, in the vicinity of intense anthropogenic activities may be laden with potentially toxic elements (PTEs), resulting in increased risk for human health. In this study we monitored three regions located in central Greece, currently cultivated with wheat: Domokos and Eretria, two areas with abandoned chromium mines, but never studied before, and the industrial area of Volos, near a major steel factory. All soils were alkaline with medium CaCO3 content. As expected, Cr was extremely high in the first two areas (705.2 in Eretria and 777.5 mg kg−1 in Domokos); Ni was also found elevated (1227 in Eretria, 1315 in Domokos and 257.6 mg kg−1 in the steel factory), while other harmful metals (Cd, Cu, Pb and Zn) were rather low. As a result, pollution load index, a cumulative index showing the contamination level of an area, was higher than 1.0 in all three areas (Eretria = 2.20, Domokos = 2.28, and steel factory = 1.61), indicating high contamination and anthropogenic inputs. As for the wheat parts (shoots and grains), they were found to have no elevated concentrations of any of the measured metals in all three study areas, probably due to the alkaline soil pH that decelerates metal mobility. This was also confirmed by the very low soil-to-plant transfer coefficient values for all metals. In assessing the possible risk concerning human health, we found that the soil-to-human pathway would induce no significant risk (exhibited by hazard index of less than 1.0), while the risk from grain-to-human resulted in considerable risk for human health in the steel factory of Volos (where HI > 1.0). Our findings suggest that rural areas never studied before with a history in some offensive anthropogenic activity can prove to be a contamination hotspot; we regard this study as a pivotal for similarly never-visited-before areas casually cultivated with wheat (or other important crops for human nutrition). We further recognize the need for a more in-depth study that would acknowledge the geochemical speciation of the studied metals and also monitor other important crops and their possible uptake of PTEs.

Cardiorenal syndrome (CRS) is described as primary dysfunction in the heart culminating in renal injury or vice versa. CRS can be classified into five groups, and uremic toxin (UT) accumulation is observed in all types of CRS. Protein-bound uremic toxin (PBUT) accumulation is responsible for permanent damage to the renal tissue, and mainly occurs in CRS types 3 and 4, thus compromising renal function directly leading to a reduction in the glomerular filtration rate (GFR) and/or subsequent proteinuria. With this decrease in GFR, patients may need renal replacement therapy (RRT), such as peritoneal dialysis (PD). PD is a high-quality and home-based dialysis therapy for patients with end-stage renal disease (ESRD) and is based on the semi-permeable characteristics of the peritoneum. These patients are exposed to factors which may cause several modifications on the peritoneal membrane. The presence of UT may harm the peritoneum membrane, which in turn can lead to the formation of extracellular vesicles (EVs). EVs are released by almost all cell types and contain lipids, nucleic acids, metabolites, membrane proteins, and cytosolic components from their cell origin. Our research group previously demonstrated that the EVs can be related to endothelial dysfunction and are formed when UTs are in contact with the endothelial monolayer. In this scenario, this review explores the mechanisms of EV formation in CRS, uremia, the peritoneum, and as potential biomarkers in peritoneal dialysis.

Tigawasa Village is one of the Old Villages or Bali Aga villages in Banjar District, Buleleng Regency, Bali which is the center of bamboo handicrafts. The local handicraft really needs development, one of the developments of the local handicrafts of Tigawasa Village, namely tourism village souvenir products. The development of local handicraft-based tourism village souvenirs is the beginning of increasing the value of local crafts in Tigawasa Village. This article describes the opportunities and challenges of developing local handicraft-based tourist village souvenirs in Tigawasa Village, which is the center of bamboo handicrafts in the Bali Aga village environment, Buleleng, Bali. The method used is a descriptive qualitative method which begins with data collection from interviews with several informants, filling out questionnaires by tourists visiting Tigawasa Village and also direct documentation to Tigawasa Village such as traditional houses and also to craftsmen in Tigawasa Village. The results show that local crafts have the opportunity to develop as souvenirs because the crafts produced are of good quality, besides that the tourism development component is also an opportunity in the development of these souvenirs such as tourists visiting Tigawasa Village will be invited to do weaving activities (something to do) with the woven results can be used as a souvenir to take home (something to buy). The results of the questionnaire also stated that 70% of tourists strongly agree with the existence of local handicraft-based tourism village souvenirs, and 30% agree and there are no opinions disagree and strongly disagree. The challenges faced related to the development of tourism village souvenirs include the limitations of existing bamboo sources so that craftsmen buy materials from outside the village so that additional capital is needed so that capital is also a challenge for Tigawasa Village crafts, lack of innovation from bamboo crafts, and lack of promotion. With the development of local handicraft-based souvenirs in Tigawasa Village can increase the selling value of local crafts, can make it a tourist attraction and as a memory for every tourist who comes to Tigawasa Tourism Village.
Excretion Patterns of Urinary Sediment and Supernatant Podocyte Biomarkers in Patients with CKD
Authors: Fukuda Akihiro , Minakawa Akihiro , Sato Yuji , Shibata Hirotaka , Hara Masanori , Fujimoto Shouichi
Published: November 2021

Background

Podocyte depletion causes glomerulosclerosis, and persistent podocyte loss drives progression to ESKD. Urinary sediment podocin (u-sed Pod) mRNA excretion and urinary supernatant podocalyxin (u-sup PCX) protein have been used to monitor disease activity in glomerular diseases. However, the differences in these markers among pathologies have not been investigated. We examined the roles of these markers in kidney diseases.

Methods

From January 2013 to March 2016, early morning urine samples were collected from 12 healthy controls and 172 patients with kidney disease (n=15 patients with minor glomerular abnormality with mild proteinuria and/or microscopic hematuria, n=15 with minimal change nephrotic syndrome [MCNS], n=15 with membranous nephropathy [MN], n=60 with IgA nephropathy [IgAN], n=19 with crescentic GN [Cres GN], n=10 with lupus nephritis [LN], and n=38 with other kidney diseases). We examined u-sed Pod mRNA excretion, u-sup PCX protein, and the urinary protein-creatinine ratio (u-PCR).

Results

u-sed Pod mRNA excretion was significantly correlated with u-sup PCX protein (r=0.37, P<0.001). Both u-sed Pod mRNA excretion and u-sup PCX protein were significantly correlated with u-PCR (r=0.53, P<0.001 and r=0.35, P<0.001, respectively). Interestingly, u-sed Pod mRNA excretion was significantly increased in proliferative-type GN—including IgAN with extracapillary proliferative lesions, Cres GN, and LN class IV—and significantly correlated with the rate of crescent formation, whereas u-sup PCX protein was significantly increased only in those with MN and subepithelial dense deposit–type LN compared with controls.

Conclusions

Higher u-sed Pod mRNA excretion and u-sup PCX protein were associated with proliferative-type GN, indicating podocyte detachment and subepithelial dense deposit–type GN, respectively. The results suggest that u-sed Pod mRNA excretion and u-sup PCX protein have usefulness for the diagnosis and measurement of disease activity with regard to glomerular diseases.

Published: November 2021

Background

AKI is a common sequela of infection with SARS-CoV-2 and contributes to the severity and mortality from COVID-19. Here, we tested the hypothesis that kidney alterations induced by COVID-19–associated AKI could be detected in cells collected from urine.

Methods

We performed single-cell RNA sequencing (scRNAseq) on cells recovered from the urine of eight hospitalized patients with COVID-19 with (n=5) or without AKI (n=3) as well as four patients with non–COVID-19 AKI (n=4) to assess differences in cellular composition and gene expression during AKI.

Results

Analysis of 30,076 cells revealed a diverse array of cell types, most of which were kidney, urothelial, and immune cells. Pathway analysis of tubular cells from patients with AKI showed enrichment of transcripts associated with damage-related pathways compared with those without AKI. ACE2 and TMPRSS2 expression was highest in urothelial cells among cell types recovered. Notably, in one patient, we detected SARS-CoV-2 viral RNA in urothelial cells. These same cells were enriched for transcripts associated with antiviral and anti-inflammatory pathways.

Conclusions

We successfully performed scRNAseq on urinary sediment from hospitalized patients with COVID-19 to noninvasively study cellular alterations associated with AKI and established a dataset that includes both injured and uninjured kidney cells. Additionally, we provide preliminary evidence of direct infection of urinary bladder cells by SARS-CoV-2. The urinary sediment contains a wealth of information and is a useful resource for studying the pathophysiology and cellular alterations that occur in kidney diseases.

При визначенні структури професійної компетентності вчителя Нової української школи ми виходили з того, що всі різновиди компетентностей, у тому числі й екологічна, є видовими поняттями по відношенню до родового поняття «компетентність», і мають однакову структуру, яка включає когнітивний, діяльнісний і особистісно-мотиваційний компоненти. Своєю чергою, компоненти екологічної компетентності майбутніх учителів Нової української школи розглянуто в пояснювально-аналітичному, прогностичному, процесуальному, діяльнісному і ціннісно-орієнтаційному аспектах. Для проведення експериментального дослідження з визначення сформованості екологічної компетентності майбутнього вчителя Нової української школи шляхом застосування в освітньому процесі системи практико зорієнтованих завдань і вправ екологічного спрямування обрано групи студентів третього і четвертого курсів денної форми навчання спеціальності 013 «Початкова освіта» Черкаського національного університету імені Богдана Хмельницького (усього близько 80 осіб). Застосовано такі методи дослідження, як тестування, самооцінювання, анкетування. Оцінювання проводилося в балах за шкалою від 1 до 10. За результатами дослідження, найкраще студентам третього курсу дається пояснення екологічних процесів у довкіллі, володіння екологічними поняттями і сучасними технологіями проведення еколого-просвітницької роботи. Натомість високих результатів у формуванні екологічної компетентності у студентів четвертого курсу досягнуто за іншими показниками: розуміння особистої відповідальності за екологічний стан довкілля; здатність передбачати екологічні зміни середовища при антропогенному втручанні; оволодіння методами проведення екологічних досліджень. Доцільність вибору в ході дослідження діяльнісного підходу підтверджено показниками процесуального (передбачає можливість знаходження процедури або способу діяльності, придатних для розв’язання екологічної проблеми) і діяльнісного (втілюється переважно в ході проектної та наукової діяльності) аспектів.
РЕТРОСПЕКТИВНИЙ АНАЛІЗ СТАНОВЛЕННЯ ТА РОЗВИТКУ ІНШОМОВНОЇ ОСВІТИ НА ПОЧАТКОВОМУ ЕТАПІ НАВЧАННЯ В ЗАКЛАДАХ ЗАГАЛЬНОЇ СЕРЕДНЬОЇ ОСВІТИ В УКРАЇНІ

У статті представлено аналіз історичних етапів становлення та розвитку іншомовної освіти на початковому ступені навчання в закладах загальної середньої освіти. Необхідність звернення до проблеми ретроспективного аналізу викликана процесами реформування та модернізації іншомовної підготовки учнів початкової школи, а також зростанням попиту на висококваліфікованих фахівців у сфері викладання іноземних мов. Ретроспективний аналіз ключових етапів розвитку дозволив виділити позитивні тенденції, які мають бути враховані у процесі підготовки майбутніх учителів іноземної мови в початковій школі. Джерельна база дослідження вміщує низку нормативно-правових та законодавчих документів, прийняття яких спричинило низку змін у іншомовній шкільній освіті та виступає критеріями виділення етапів розвитку іншомовної освіти у початковій ланці. Узагальнений аналіз досліджень вітчизняних науковців дозволив також окреслити особливості навчання іноземної мови в початковій школі в різні історичні періоди. Метою статті є проаналізувати період навчання іноземних мов в початковій школі в Україні від початку ХХ століття (1931 р.) по теперішній час, виділити етапи навчання іноземної мови на початковому етапу навчання в закладах загальної середньої освіти, окреслити позитивні тенденції, які мають бути враховані у процесі професійної підготовки майбутніх учителів іноземних мов у початковій школі. Автором визначено чотири етапи становлення та розвитку іншомовної освіти в початковій школі, а саме: перший етап – запровадження навчання іноземних мов в початковій школі та зародження методики навчання іноземної мови – який тривав із 1931 року по 1984 рік; другий етап тривав із 1984 року по 1991 рік – період проведення ключових реформ та запровадження інновацій у викладанні іноземних мов; третій етап (1991–2016 рр.) характеризувався орієнтацією на зарубіжний досвід викладання іноземних мов в практиці вітчизняної початкової школи; четвертий етап спричинений прийняттям Концепції «Нова українська школа» (2016 року по теперішній час) – комплексна реалізація компетентнісного навчання іноземних мов. Вивчення особливостей розвитку іншомовної освіти на різних історичних етапах дозволило визначити позитивні тенденції, які мають бути враховані у підготовці майбутніх учителів іноземної мови в початковій школі, зокрема: розроблення методичних основ підготовки вчителів іноземної мови для початкової школи; урахування іноземного досвіду навчання іноземних мов; запровадження інноваційних технологій та засобів навчання; надання переваги культурологічному підходу, що дозволяє сформувати систему соціокультурних знань учителів.
КУЛЬТУРНО МАРКОВАНА ЛЕКСИКА ЯК ЗАСІБ ОБ’ЄКТИВАЦІЇ КОНЦЕПТУ СТАТУС (на матеріалі британського художнього дискурсу)
Authors: Бєлова М. О.
Published: November 2021

У роботі висвітлено особливості об’єктивації концепту СТАТУС за допомогою культурно маркованої лексики в британському художньому дискурсі. Зазначено, що в разі об’єктивації концепту в мові й мовленні він набуває статусу лексичного концепту. Лексикалізація концепту передбачає його об’єктивацію за допомогою лексичної системи мови, зокрема й культурно маркованої лексики (реалій, денотативно маркованої та конотативно маркованої фонової лексики), яка віддзеркалює культурну інформацію на різних рівнях структури концепту. У процесі дослідження виявлено типи культурно маркованої лексики, що залучаються для об’єктивації концепту СТАТУС у британському художньому дискурсі, встановлено, які ознаки концепту вони віддзеркалюють і яке місце в структурі концепту вони посідають
É proibido ser
Authors: Joia Cha Renato
Published: November 2021

O poeta é um ser singular. Ele guarda um poder tão incompreensível dentro de si, uma profusão tão imensurável de sentimentos, que quando extravasa, é como uma força da natureza, incontrolável, incontornável. Por isso, muitos poetas se perdem no caminho, preferindo esconder-se, ocultando seu “eu verdadeiro”, por temerem as consequências de liberarem tanta energia numa sociedade tão avessa àquilo que destoa. O “esconder a si” acaba se tornando uma defesa, uma forma de proteger os nervos expostos, a alma desencapsulada. Nossa sociedade teme as nossas verdades, teme a liberdade de sermos quem devemos e queremos ser. É proibido ser é mais do que um livro de poesias, é o momento de coragem de um ser que sai de seu casulo, que aprende a dizer ao mundo, em uma arte visceral, em versos e desenhos, quem é e quem pretende ser.

FRONTAL BONE ANATOMY OF TERATOPHONEUS CURRIEI (THEROPODA: TYRANNOSAURIDAE) FROM THE UPPER CRETACEOUS KAIPAROWITS FORMATION OF UTAH
Authors: YUN CHAN-GYU
Published: November 2021

A right frontal bone belonging to the tyrannosaurid theropod Teratophoneus curriei from the Campanian Kaiparowits Formation of Utah provides important anatomical information that is useful in understanding tyrannosaurid taxonomy and relationships. Many aspects of its anatomy indicate a subadult ontogenetic status of this individual, as they compare favorably with subadults of other tyrannosaurids such as Daspletosaurus torosus and Tyrannosaurus rex. This is consistent with the previous interpretation that this individual was subadult, based on different cranial bones such as lacrimal or maxilla. It is likely that a previous assessment of the body mass of this individual was underestimated, and it is presumed here that it was most likely around 1000 kg. This description of the frontal anatomy has several implications for previous works on tyrannosaurid cranial anatomy, and information that corrects aspects of our understanding on tyrannosaurid frontal anatomy is provided. Reanalysis of Nanuqsaurus hoglundi, a tyrannosaurid theropod that has similar frontal morphology with Teratophoneus curriei, implies that parts of its diagnosis are problematic and the proposed evidence for the supposed diminutive body size of this taxon is weak.
Globalización y Educación: repercusiones del fenómeno en los estudiantes y alternativas frente al mismo
Authors:   , Domench Ana Laura
Published: November 2021

El propósito de este estudio es analizar cómo repercute el fenómeno de la globalización en el marco de la educación e intentar determinar su influencia en la realidad universitaria. En la medida que el proceso de globalización se incrementó, algunos aspectos de la educación se vieron favorecidos o potenciados, mientras que en otros aspectos se perciben notorias deficiencias y falencias estructurales. En primer lugar, se analiza en el marco teórico las múltiples facetas del fenómeno de la globalización, luego, se intenta comprobar la siguiente hipótesis: “Los alumnos cursantes de distintas unidades académicas de la Universidad Nacional de La Plata relacionan la influencia del proceso de la globalización en su aprendizaje". Para demostrarlo, se realizó una investigación que, según el análisis y alcance de los resultados, podemos definirla por ser un estudio exploratorio, transversal, descriptivo y analítico.
