Costs Associated With Mitigating Boxwood Blight During Nursery Production in the U.S.
Authors: Hall Charles R.
Published: December 2024

Three scenarios commonly used for nursery production of boxwood (Buxus L. spp., Buxaceae) in #3 containers [11 L (3 gal)] in the U.S. were modeled based on published best management practices and grower interviews. Detailed inventories of material inputs, equipment use, and labor were developed from the production protocols for each of those scenarios and a partial budgeting analysis was conducted to determine the impact of individual components on the economic costs of the finished shrubs at the nursery gate. The total variable costs of each plant from Scenario A (from propagation tray to #1 container to #3 container) were $8.98. Scenario B (propagation tray to the field and back to #3 container) resulted in variable costs of $9.19 and takes a year longer in production than the other two models. Scenario C (propagation tray to #1 container bumped up into a #2 container and finally to a #3 container) incurred variable costs of $11.26 per plant. Labor comprised the greatest share of variable costs in each of the three scenarios, while containers, transplants (including transplanting labor), irrigation, and fertilization inputs and associated activities accounted for the greatest portion of materials costs in each scenario. Pruning, assembling orders and loading trucks, applying plant protection products, and chlorination were other important components of variable costs of each scenario.

Published: December 2024

Vegetable, fruiting, and ornamental crops that utilize plugs for horticultural production have demonstrated better plant health, transplant establishment rate, and total yield. The APS Laboratory for Sustainable Agriculture investigated the quality of plugs prepared based on different commonly used growth mediums in comparison to soil plugs. We evaluated the growth of ‘Rex Butterhead’ lettuce (Latuca sativa L.) plugs with six different treatments: 1) rockwool, 2) Oasis® Horticube, 3) perlite 4) coco coir, 5) phenolic foam, and 6) peat pellets. The plants were then cultivated for 15 days in a controlled environment until two leaves after the cotyledon had developed. After 15 days, we collected data which included wet weight, dry weight, leaf area, nitrogen content, and chlorophyll concentration. In addition, we derived data including the Leaf Area Index (LAI) and Specific Leaf Area (SLA). A permutation MANOVA revealed a significant treatment effect on plug preparation (p < 0.01). Of all the treatments, we concluded that plugs grown in peat pellets produced the most viable plugs with the largest wet weight, dry weight, and total leaf area. Results from this study may inform growers about appropriate growth mediums for efficient plug production.

Authors: Jurczak Marlena Anna , Harasymiuk Jolanta , Szafranko Elżbieta
Published: December 2024

One of the most important things to do at the stage of preparing an investment process in the construction business is to develop a few possible solutions and then to choose the variant which best fulfils the expectations of various groups of stakeholders. Making a decision about which variant to select depends on how it satisfies a number of criteria, which in turn reflect the requirements set for the planned investment. The process analysing variant solutions employs multi-criteria analysis methods. In order to make analyses and to identify the importance of measurable and non-measurable criteria, surveys and interviews are carried out to acquire the information on the role of the previously defined criteria. Opinions given by experts tend to be divergent due to differences in education, professional background as well as various professional and private experiences. This article reviews data processing methods, and discusses an example of a procedure, which is part of a more extensive analysis of the route of a planned road. The case presented in this paper focuses on the evaluation of five criteria from the category ‘impact on the natural environment’, which are significant in such development projects. The calculations involved in this assessment proved to be time- and labour-consuming, while raising a number of doubts concerning the stage of data aggregation. Hence, the objective of this study has been to develop a method that will enable more efficient data processing while taking into account all assessments.

Authors: Krystosik Dorota
Published: December 2024

The paper focuses on presenting the methodology of testing corner joints along with the presentation of obtained results. The objective of the conducted research was to experimentally determine the behaviour of welded knees with slender webs under similar loading condition that occur in the knee joints of portal steel frames. Laboratory tests were carried out on a specially prepared testing stand. During the laboratory work, load tests were performed on three identical knees. The testing stand was equipped with measurement equipment, including two data acquisition systems: the SAD 256 for displacement and force sensors, and the Pontos/Aramis – a digital image correlation system. The first knee test served as a verification of the testing stand and the adopted data collection method. After implementing certain changes to the stand, the remaining load tests on the knees were conducted. Based on the conducted studies and data analysis, moment-rotation M–ϕ characteristics of the joints were determined, along with parameters such as initial stiffness S, elastic bending resistance Mel and ultimate bending resistance Mu.
Resistance and stiffness assessment of reinforced column base using the component method
Authors: Krystosik Przemysław
Published: December 2024

The article presents an algorithm for assessing the resistance and stiffness of a reinforced column base, which is based on the component method. The main part of the study formulates a mechanical model of the reinforced column bases, in the form of a stiffened base plate fixed to the concrete by eight anchor bolts. The adopted structural solution was analyzed using the component method for calculations. By referring to standard guidelines and existing literature, the mechanical properties, such as resistance and stiffness, of individual components of the column base are determined. Equivalent mechanical models were then formulated using equilibrium conditions and deflection compatibility, enabling the derivation of formulas for the bending resistance Mj .Rd and the initial stiffness Sj .ini of the entire column base. In the final part of the work, a comprehensive numerical example is provided to demonstrate the application of the presented method in calculations of the reinforced column bases.

Authors: Kostrzewa-Demczuk Paulina , Rogalska Magdalena
Published: December 2024

Effective planning is crucial in the construction sector to ensure projects are completed on time and on budget. However, the construction industry faces various challenges that can complicate the planning process. There are often delays, exceedances of the baseline and increases in investment costs. One planning method is Time Couplings Methods (TCM), which can be improved using predictive multivariate statistical model method (MMSM) construction process times and standard deviations. A new scheduling method in the probabilistic approach was developed – Probabilistic Time Couplings Method II (PTCM II). In PTCM II, the priority is to maintain the continuity of work on working sectors, because sector downtime is unfavorable and extends the investment implementation time. The work presents a case study and compares it with other planning methods and with the real time of the considered investment. he results clearly indicate that the developed methodology is correct, provides good mapping and can be successfully used in planning construction works.
How to achieve sustainable operation of transport infrastructure development: a case study of 30 transport infrastructure projects in China
Authors: Chen Jie , Ma Chongsen
Published: December 2024

Transport infrastructure projects are distinguished by their high levels of investment, lengthy construction periods, and reliance on government subsidies during operation. These factors have far-reaching impacts, not only on the sustainable operation and success of the projects themselves, but also on the orderly functioning of society and the sustainable development of the economy. As such, it is of paramount importance to thoroughly investigate the sustainable operation of transport infrastructure. This paper examines the impact of sustainable operation on transport infrastructure by analysing 30 projects in China’s transport infrastructure sector. The study employs the qualitative comparative analysis method. To achieve the aim of this paper, we identified five dimensions for assessing a project’s sustainability. These include the economic environment of the construction site, operational market demand, government support capacity, and enterprise management level. This analysis offers valuable guidance for future engineering projects. Finally, the study identified seven strategies for achieving sustainable operation of the project. The findings revealed that the economic development status, population size, and government subsidies of the construction site do not effectively promote sustainable operation of the project. Rather, they can hinder enterprises’ market competitiveness. The study’s results can assist decision-makers in determining the feasibility of implementing sustainable management practices in the new project. Examine the factors that influence the achievement of sustainable business while enhancing the operational efficiency of ongoing initiatives. This research aims to produce a valuable addition to risk assessments in sustainable operation research and the advancement of transportation infrastructure reduction.

Authors: Song Shijiu , Zhou Li
Published: December 2024

The energy consumption of air conditioning systems accounts for more than 50% of building energy consumption. The supercooled and overheated environment provided by intelligent buildings can bring a large amount of energy loss. How to create comfortable spaces with energy-saving goals is currently the focus of research. The aim of this study is to improve the accuracy of human thermal discomfort pose recognition algorithms. This study first extracts human key points on the ground of bone key points, then normalizes the data, and finally constructs a human thermal uncomfortable posture recognition algorithm on the ground of deep learning technology. The experiment showcases that in the training set, when the iteration number is 1500, the accuracy reaches its maximum value, which is 99.98%. In the test set, the accuracy reached its maximum value of 89.85% when the iteration number was 400. After classifying the dataset, the accuracy of the first type dataset reached 99.51%. The accuracy rate of the second type dataset is 98.56%, and the accuracy rate of the third type dataset is 98.95%. In the comparison of the four algorithms, the accuracy of the research algorithm is significantly higher than the other three algorithms, indicating that the research algorithm can accurately recognize the thermal uncomfortable posture of the human body. This research algorithm can timely and effectively identify the uncomfortable posture of the human body, thereby automatically adjusting indoor temperature and achieving energy conservation and emission reduction.
Impact coefficient of tied arch bridges considering heavy transport vehicles
Authors: He Shu-Qi , Li De-Jian
Published: December 2024

Analyzing the impact coefficient of tied arch bridges considering heavy transport vehicles is important for safety assessment. There are few studies on the vehicle-bridge coupled dynamic analysis involving heavy transport vehicles passing through bridges. In order to properly evaluate the impact coefficient of heavy transport vehicles passing through tied-arch bridges, this study takes an 80 m-span tied-arch bridge as an example. Based on the ANSYS platform, a vehicle-bridge coupling model under the load of low-speed heavy transport vehicles is established. By analyzing the vibration characteristics of the vehicle-bridge coupling system, the influence of vehicle speed and load on the impact coefficient of the bridge is discussed. The results show that even when the vehicle travels at a speed of 2 m/s under Class B roughness, the maximum impact coefficient reaches 0.061 when the vehicle is 4 m/s. When evaluating the passage of heavy transport vehicles over tied-arch bridges, the impact effect should be considered even at low speeds. The influence of vehicle load on the internal force impact coefficient of tied-arch bridges is greater than that of the displacement impact coefficient. When the vehicle load is large, the impact on the bridge is small, but an excessive increase in vehicle load will increase the burden on the bridge. A load of 400 t is considered a more ideal value.
The Role of Molybdenum in the Formation of the Microstructure and Properties of Al-Cu Alloys
Authors: Stąpór S. , Górny M. , Gondek Ł. , Gracz B. , Kawalec M.
Published: December 2024

The subject of the presented research is the influence of molybdenum on selected properties of alloys that are based on the Al-Cu system. It could be observed that the introduction of molybdenum to the multi-component alloy at levels of up to 0.5 wt.% showed increases in the degrees of undercooling ΔT along with the increasing contents of the introduced element. The addition of molybdenum contributed to the reduction of the size of the primary grains of the α(Al) phase. Molybdenum improved the strength of the alloy while achieving elongation at a significant level. This is an element that occurs in the alloy – both in the iron-manganese phases and in the segregates inside the grains. Most of the iron-manganese phases occurred in a more spheroidal form. Additionally, tests were carried out on higher molybdenum content in the alloy. The addition of the tested chemical element at a level of 1 wt.% caused the precipitation of the phases that contained molybdenum, which did not dissolve after heat treatment.
Introduction of Powder Fluxes in Rotary Degassing System Towards Intensifying Refining Process of Aluminium Alloys
Authors: Piękoś M. , Smorawiński Z.
Published: December 2024

This paper presents and describes the research capabilities of a prototype experimental bench for realising the composite processing of liquid aluminium alloys by involving gas refining by rotary degassing technology and refining with salts (fluxes) in powder form. The constructed unit was installed in the Experimental Foundry of the Faculty of Foundry Engineering at AGH in the Department of Moulding Processes, Mould Technology, and Non-Ferrous Metals Foundry; it is an integral part of a thyristor-based medium-frequency induction furnace with a melting capacity of up to 60 kg for aluminium alloys. The new experimental bench performs barbotage refining using a rotating head with the possibility of alternating the introduction of refiners/modifiers in powder form. This method can be used in casting lines: continuous in reactors, or batch in ladles. The innovation of the design of the stand and the treatment of the liquid metal with powdered additives consists of dosing the refiner fluid deep into the metal bath through a channel that was made in the rotor axis and the head; this differs from conventional methods in the small amounts of introduced salts and, at the same time, in the very good metal-inert gas-salt homogeneity of the treated metal bath. This method of dosing the refining salts increases the efficiency of their use, reduces any losses, and limits the formation of post-refining slag (thus, minimising the negative environmental effect). The feedstock that was used for the test smelts consisted of recycled materials: aluminium 99.7 (in the form of wires of various cross-sections that were used in electrical engineering – so-called ‘SECTOR’), and the sub-eutectic AlSi7Mg0.3 alloy (in ingot form). The scope of the tests included verifying the technical solutions that were adopted for the dosing of the bulk materials in the form of a fluid, selecting the melting temperature, and dispersing (distributing) the materials in the bath via the rotor head. The results of the trials were reviewed in terms of the changes in the hydrogen content of the performed process and information on such powder-flux-introduction parameters as the type of the rotor head and the melting temperature of the powder flux. Preliminary trials showed that the performed complex refining (rotary degassing + refining with salts being blown as a fluid into the lower parts of the liquid metal) allowed us to reduce the hydrogen content to a level that could not be achieved by gas refining alone.
„Od zawsze chciałam coś robić” – ścieżki i motywacje młodych aktywistek i aktywistów w Polsce
Authors: Kajta Justyna , Barakeh Sylwia , Marczewski Paweł
Published: December 2024

Artykuł podejmuje tematykę społeczno-politycznego zaangażowania młodych ludzi w Polsce. Przyjmując za punkty wyjścia teoretyczne rozważania dotyczące takich pojęć, jak polityczne i obywatelskie zaangażowanie, oraz stan badań na temat motywacji do zaangażowania, autorzy koncentrują się na ścieżkach aktywistycznych młodych dorosłych: (1) w jakich okolicznościach rozpoczyna się i rozwija ich zaangażowanie; (2) co ich do niego motywuje – zarówno w pierwszym, jak i kolejnych etapach, oraz jak te motywacje zmieniają się w czasie. Artykuł opiera się na analizie 28 wywiadów z młodymi aktywistami i aktywistkami (18–24 lata) związanymi z co najmniej jednym z trzech obszarów zaangażowania: instytucjonalno-politycznym (polityczne młodzieżówki, partie polityczne, samorządy); społeczno-politycznym (ruchy i organizacje społeczne o ogólnopolskim oddziaływaniu) i społeczno-lokalnym (ochotnicza straż pożarna, lokalne organizacje pozarządowe działające na rzecz społeczności lokalnej).
Wytwarzanie oporu w ramach mobilizacji na rzecz praw kobiet
Authors: Krzemień Magdalena
Published: December 2024

Głównym celem tego artykułu jest analiza różnorodnych form wytwarzania oporu mających miejsce podczas Protestów Kobiet (2020–2023). Swoją refleksję osadzam w kontekście teorii oporu, materialności i wizualności. Przeanalizowałam 19 epizodyczno-narracyjnych wywiadów, które są częścią moich badań magisterskich. Korzystając z różnorodnych narzędzi teoretycznych i metodologicznych, poddaję wspomniane narracje ustrukturyzowanej analizie, a następnie opisowi. Uwagę koncentruję na eksplorowaniu różnorodnych sposobów podejmowanego zaangażowania przybierających różne od siebie kierunki (np. negacyjny, emancypacyjny). Zwracam również uwagę na rodzaje aktorów biorących udział w oporze – zarówno tych materialnych, jak i niematerialnych – oraz formujące się pomiędzy nimi relacje. Dzięki temu włączam w badanie oporu nie tylko perspektywę ludzi, ale również materialną soczewkę umożliwiającą rozszerzenie i ponowne podjęcie istniejących w literaturze antropocentrycznych analiz.
Widoczna i niewidoczna religia. Negocjowanie obecności religii w pracy zawodowej przez rzymskie katoliczki
Authors: Szwed Anna
Published: December 2024

Artykuł koncentruje się wokół problematyki związków między religią a pracą. Wykorzystując ramę teoretyczną lived religion i odwołując się do wyników badań jakościowych, pokazuje, w jaki sposób wykształcone, zaangażowane religijnie, wielkomiejskie rzymskie katoliczki w Polsce negocjują obecność religii w pracy i jak widzą jej rolę w swojej aktywności zawodowej. Zjawiska te analizowane są z perspektywy intrapersonalnej, związanej z nadawanymi pracy znaczeniami, postrzeganiem jej jako źródła wsparcia i sprawstwa, oraz interpersonalnej, odnoszącej się do relacji ze współpracownikami. Zaprezentowana w artykule analiza pokazuje, że choć badane przez nas katoliczki otwarcie nie kwestionują sekularnego charakteru miejsca pracy, to na poziomie praktyk podział na to, co religijne i świeckie, jest podważany, a samo znaczenie tych dwóch wymiarów redefiniowane. Obecność religii w środowiskach pracy bardziej niż jako pewne status quo można zatem interpretować w kategoriach ukontekstowionego procesu uwidoczniania i uniewidoczniania religii.

In recent years, it has been realized that agriculture has become one of the economic sectors with a huge impact on the environment. Therefore, measures have been taken to reduce the negative impact of agricultural production on the environment. The use of biostimulants in agriculture, especially of plant origin, is part of this trend. However, obtaining suitable formulation of biostimulants requires the development of appropriate technologies for their production. Therefore, it was undertaken to investigate the possibility of using gliding arc cold plasma (GA) and low-pressure microwave (MW) discharges to produce water plant extracts with biostimulating potential. An increase in total polyphenol content and antioxidant activity was observed, indicating the high potential of using low-pressure microwave discharge to produce effective plant biostimulants. Also, low-pressure microwave discharge improved the extraction of elements such as Ca, K and Fe.

The growing concerns over antibiotic resistance and the need for safer alternatives in broiler production make exploring natural additives like plant extracts imperative to enhance broiler health and performance. This study evaluated the effect of aqueous bamboo leaf extract (BLE) in drinking water on broiler chickens’ performance, haematological indices, and blood oxidative status. Ninety-six Ross 308 one-day-old broilers were randomly assigned to four treatments: T1 (Control, ordinary water), T2 (antibiotics (Tetranor 5% at 5 g per litre of water)), T3 (50 ml BLE per litre of water) and T4 (100 ml BLE per litre of water), each with four replicates of six birds. Performance data were recorded weekly over 8 weeks, and blood samples were collected on day 56 for haematological and oxidative status analysis. Data were analysed using SAS (2000) with means separation via Tukey’s test. Results showed that broilers that consumed water containing 100ml/L BLE had the highest (p < 0.05) live weight (LW) of 1078.20 g and weight gain (WG) of 1029.19 g at the starter phase. At the finisher phase, broilers in the 100ml BLE group had the highest (p < 0.05) LW (2695.42 g) and zero mortality, whereas the control group recorded the lowest LW (1672.95 g). The feed conversion ratio (FCR) was improved (p < 0.05) in broilers that had access to water containing 100 ml/L BLE at both phases. Haematological analysis revealed increased (p < 0.05) packed cell volume and haemoglobin concentrations in the 100 ml/L BLE group. Oxidative stress markers showed lower (p < 0.05) malondialdehyde levels for broilers in the 100 ml/L BLE group than those in the control group. Superoxide dismutase was reduced (p < 0.05) for broilers given ordinary water and those given antibiotics but increased for broilers with 100 ml/L BLE. In conclusion, including BLE at 100 ml/L in drinking water enhanced weight gain, FCR, and survival rate while reducing oxidative stress, indicating a promising natural alternative for improving broiler health and performance.

Новые радиоуглеродные даты неолитических памятников Среднего Поволжья и Камско-Вятского междуречья
Authors: Андреев Константин Михайлович , Кулькова Марианна Алексеевна , Петрожицкий Алексей Валентинович
Published: December 2024

За последние несколько лет авторами получено 30 новых радиоуглеродных дат по двенадцати стоянкам обозначенных в названии статьи регионов. Радиоуглеродный анализ проводился при помощи жидкостного сцинтилляционного метода и метода ускорительной масс-спектрометрии. Анализ осуществлялся по развалам или скоплениям керамики и каждое значение относится к строго определенному сосуду. Для лесостепного Поволжья получена серия из 15 датировок по слабо орнаментированной посуде и сосудам, украшенным прочерками, насечками или оттисками гребенчатого штампа. Большинство значений хорошо согласуется с массивом существующих дат для неолитических комплексов региона и укладывается в диапазон середины VI – середины V тыс. до н.э. С территории лесного Среднего Поволжья осуществлено датирование пяти образцов. Часть из них подтвердила ранее сделанные специалистами предположения, другие позволяют ставить вопрос о длительности бытования традиции изготовления неорнаментированной посуды в регионе. Впервые для Камско-Вятского междуречья по шести образцам нагара методом АМС получена группа из 10 дат. Результаты достаточно противоречивы. В ряде случаев, вероятно, они свидетельствуют о влиянии резервуарного эффекта, связанного с приготовлением рыбной пищи. В остальных дополняют имеющиеся немногочисленные датировки.
К вопросу о культурном статусе ранненеолитических памятников лесного Среднего Поволжья
Authors: Кудашов Александр Сергеевич
Published: December 2024

В представленной статье разбирается аспект о культурной принадлежности Марийских памятников, относимых исследователями к раннему неолиту. Проводится анализ имеющихся версий относительно происхождения традиции. Сравниваются и хронологически близкие комплексы, которые могли бы воздействовать на лесное Среднее Поволжье. Приводимые отличительные черты на памятниках Подонья, Приднепровья, Верхнего, а также Нижнего Поволжья не позволяют объединять их с материалами лесного Среднего Поволжья. Основным ранненеолитическим компонентом для сопоставления является керамика. Традиция ее изготовления и типологически и технологически близки к елшанскому ареалу гончарных навыков. При этом, отмечаемые в начальной стадии неолита интересуемого региона группы керамики, имея сходства с лесостепным Поволжьем, представляют собой неодинаковые комплексы. Если неорнаментированная посуда близка луговскому типу, то керамика, украшенные наколами находят аналогии в ранней средневолжской культуре. Найденный сосуд елшанского типа может характеризовать связь регионов и немногим более древнее вышеуказанных традиций. Все это позволяет выдвинуть предположение о включении Марийских ранненеолитических материалов в северную периферию поздней елшанской и ранней средневолжской культуры.

Статья посвящена развернутой характеристике волго-уральской культурной группы. Она занимала степи одноименного региона в финале средней бронзы, входит в блок посткатакомбных культурных образований и является неотъемлемой частью культурного круга Лола. Группа представлена подкурганными и грунтовыми захоронениями. Основными элементами ее наглядного образа являются адоративный обряд и ориентировки в южный сектор. Отдельный интерес представляет обрядовая группа, которую составляют погребения, совершенные в сидячей позе или ее имитации. В своем развитии группа прошла два этапа в пределах периода 2200–2000 CalBC. Своим происхождением волго-уральская культурная группа была связана с лолинской культурой, а ее историческая судьба тесно связана с формированием синташтинских древностей.

Published: December 2024

Objective: Showing the shortcomings of operational risk management in universities that inhibit the achievement of strategic objectives and organizational goals is the central objective of this research.
 
Method: To this end, a diagnosis of the current state of the associated variables was carried out in accounting and administration faculties in Mexico, Ecuador and Cuba.
 
Results and Discussion: Among the main findings, it is highlighted that the most affected dimension is the Strategic orientation design of the organization for risk management, although in general, none of the dimensions evaluated presents a favorable behavior, which indicates the need to apply risk management tools with a strategic and integrated approach and a greater follow-up of prevention plans to achieve a better correspondence between planning and control.
 
Originality/Value: This study contributes to the literature by providing a systematization of knowledge available in scientific literature on risk management in higher education institutions to subsequently verify the behavior of these variables in higher education institutions that operate in contexts as diverse and different as they belong to countries like Mexico, Ecuador and Cuba that respond to different socio-economic environments.

Wersologiczna redundancja w arabskiej nauce o wierszu
Authors: Siwiec Paweł
Published: December 2024

Arabska wersologia (ᶜarūḍ) narodziła się w Basrze w ósmym stuleciu. Jej twórca Al-Ḫaliīl ibn Aḥmad al-Farāhīdī był jednym z filarów tamtejszej szkoły gramatyków. Do pracy nad teorią wiersza przystąpił z właściwą dla owego środowiska uczonych analityczną drobiazgowością, obierając za przedmiot swojej analizy prozodyjnej materię tekstu pisanego. Niniejszy artykuł wykazuje, iż ubocznym efektem takiego podejścia jest redundancja w arabskim opisie struktury rytmicznej wiersza. Przedstawia też skalę tego zjawiska obecnego po dziś dzień w arabskiej wersologii.

Posługując się pytaniami podsuwanymi przez intymną i emocjonalną historię nauki, autor stara się usytuować dzieje nauki o wierszu poprzez przybliżenie osobistej perspektywy Mayenowej i jej współpracownic, wykorzystując jako materiał do analizy przede wszystkim archiwalną korespondencję oraz teksty wspomnieniowe. Z artykułu wyłaniają się dwie zasadnicze tezy. Pierwsza stanowi, iż uprawianie wersologii w PRL nie było wyborem ideologicznie obojętnym, ponadto z samej swej natury umożliwiało czynienie określonych aluzji politycznych. Druga teza jest natomiast taka, że zarówno specyfika prowadzonych badań, jak i styl wywodów były w przypadku Mayenowej i jej współpracownic koherentne względem przyswojonego przez nie modelu wychowania społeczno-kulturowego, etosu pracy, wyznawanych wartości i światopoglądów. Innymi słowy, to, że warszawska wersologia była po wojnie właśnie taka, jaka była, wynikało ze specyficznego splotu przyczyn biograficznych, historyczno-politycznych oraz społeczno-kulturowych.

The objective of this research is to ascertain the influence of consumer ethnocentrism and the perceived image of a country's products on the purchasing intentions of Indonesian consumers with respect to goods originating from China. The conceptual framework of the study was formulated on the premises of ethnocentrism theory, product image perceptions, and the determinants of consumer purchase intent. This research is a qualitative descriptive research using in-depth interviews with 10 informants. The results of the study reveal that consumer ethnocentrism is attached to the purchase of domestic goods with the assumption that the goods are of high quality and have very competitive price competition with foreign goods. In Indonesia, the people already have a stigma that goods originating from China are indeed cheap. The perception of product image plays a significant role in shaping the intention to purchase imported goods from China. Indonesian enterprises have the opportunity to harness consumer ethnocentrism by designing marketing strategies that foreground nationalistic aspects, highlighting the national identity and features of domestically sold products. These strategies can be deployed as overt messages to increase the efficiency of communication or to enhance the positioning of the company's image.

A study on the social status of indigenous women in Rangpur, Bangladesh
Authors: Mondol Beauty , Paul Basudev
Published: December 2024

Our society has not been able to break free from the subcontinent’s conservative patriarchy. There is a tendency to oppress women in society. For indigenous women, the situation is worse considering ethnicity, gender, religion, identity, and class. However, indigenous women in Bangladesh face numerous crises due to existing political, economic, and cultural barriers and inequalities. This study explored indigenous women’s social status in Bangladesh’s Rangpur region. This research followed the qualitative method to gather data in the field through FGD (Focus Group Discussions) and KID (Key Informant Interviews). The study’s findings show that lack of education, child marriage, prejudice, occupational oppression, insecurity, male superiority, the culture of forcing their decisions on women, and a lack of property rights are the most significant barriers to indigenous women’s growth in the Rangpur region. Furthermore, owing to the lack of adequate access to electricity, the internet, newspapers, and television in this region, they are deprived of the free flow of the media. As a result, women are unaware of various matters, such as government-allocated facilities, budget allocation, initiatives, work plans, and policies, making their challenges more visible. In the face of such multi-faceted problems in indigenous communities, the services and benefits of the government of Bangladesh, BRAC, Grameen Bank, CCDB, and World Vision are inadequate or absent in some areas; several NGOs, such as RDRS and Caritas, are just beginning. On the other hand, NGOs are more interested in microcredit practices than in developmental activities. The findings further show that the thinking and lifestyle of indigenous women of Rangpur region are improving through modernization. Many women from indigenous communities are now working as physicians, police officers, and teachers, while many are studying at colleges and universities.
Enhancing students' critical thinking skills through mobile technology: An analysis of problem-based learning implementation in heat material instruction

Published: December 2024

This study discusses the analysis of students' critical thinking skills profile and the implementation of PBL on heat material. This study aimed to determine the profile of students' critical thinking skills and the implementation of PBL on heat material at SMAN 1 Gondang. This study used pre-research with qualitative descriptive analysis with a sample of 91 SMA Negeri 1 Gondang students. Data collection techniques were written tests, student response questionnaires, and teacher interviews. The study found that students critical thinking skills were in a low category, and inference was the indicator of essential thinking skills with the lowest average. Teachers still used lecture methods and conventional teaching materials during learning, so it was necessary to apply a model, namely a problem-based learning model assisted by a 3D module, which was expected to improve critical thinking skills on heat material. Learning innovations need to be carried out to improve students' critical thinking skills, especially in physics learning, one of which is the application of Problem-Based Learning assisted by a 3D module.
Las armadas de los Habsburgo en Oriente (1565-1640). Socorro novohispano e industria naval filipina
Authors: Amaya Palacios Sebastian
Published: December 2024

Con la colonización castellana de Filipinas emergió una rica ruta mercantil entre Acapulco y Manila. Al ser un derrotero marítimo, requería una enorme industria naval a ambos lados del Pacífico para sustentar las embarcaciones que realizaban este tráfico. Este texto propone una lectura de la historia naval del Pacífico a partir de las dificultades que implicó la construcción de la armada de Legazpi, esfuerzos por crear guardacostas en Manila, e importancia de los socorros de plata mexicana y mano de obra filipina para asegurar los litorales de Hispanoasia. Se consultaron las misivas de gobernadores, cabildo y Audiencia de Manila rastreando alusiones a la proyección naval que los Austrias proyectaron en Oriente.

RESUMO – Este trabalho analisa como duas agências de checagem, Lupa e Aos Fatos, utilizaram-se de ferramentas de transparência pública na verificação de desinformação difundida digitalmente em 2022. Por meio de análise de conteúdo, identificou-se 63 checagens com ferramentas de transparência, o que representou menos de 7% do total das checagens realizadas (950). Contudo, tais ferramentas se mostraram decisivas para as verificações envolvendo assuntos, agentes e autoridades públicas. Discutimos as implicações desses resultados para o papel ocupado pelas agências de checagem no enfrentamento à desinformação e no seu apoio declarado à defesa da democracia brasileira.
ABSTRACT – This paper analyzes how two fact-checking agencies, Lupa and Aos Fatos, utilized public transparency tools in verifying misinformation spread digitally in 2022. Through content analysis, 63 checks were identified using transparency tools, which represented less than 7% of the total checks conducted (950). However, such tools proved decisive for verifications involving subjects, agents, and public authorities.

The Image of the Altai in A. I. Makarova-Mirskaya’s Short Stories for Children (“Alataiskie rasskazy” [“Altai Short Stories”], 1912)
Authors:   Institute of Philology of the Siberian Branch of the Russian Academy of Sciences Novosibirsk, Russian Federation, Nepomnyashchikh N.A.
Published: December 2024

A. I. Makarova-Mirskaya was one of the first writers to create the image of the Altai in children’s literature. In her short stories, Altai is pictured as a special place where Good triumphs
over Evil and paradisiacal nature shows all the beauty of God’s Creation. The Altai in her stories appears as a primordial land, not yet spoiled by man. Here the righteous religious men
live in harmony with the world around and with each other. The book is conceptually whole
and forms an idea that the Altai’s value is greater than the value of a just geographically remarkable place; it is a sacred and miraculous land. This idea has been further developed in
Russian literature and culture. The Altai short stories (1912) were one of the sources of this
tradition. Children in the book guide readers to miracles unnoticed by adults. Everything that
happens in the stories and all surroundings are shown through children’s eyes and perception.
The texts are intelligently complemented with the illustrations: G. I. Gurkin’s (Choros
Gurkin’s) drawings and photos taken by Makarova-Mirskaya herself. All components of the
book are devised to instill the idea of the Beautiful Altai, which is “a miracle itself”.
