Marketing of craft producers
Authors: First Komen Ivana , Mijatović Matea
Published: July 2024

Craft producers often drive tourist and the overall economic development of small communities; therefore, their business success extends beyond their own benefit. This research was therefore driven by the idea to support craft producers in achieving market success. The purpose of the research was to understand how craft producers approach marketing and what their needs are in terms of marketing education. We approached the research by inquiring insights directly from craft producers interested to improve their marketing knowledge and collecting qualitative data by questionnaires with open-ended questions. The results show that surveyed craft producers give considerable thought to developing marketing mix elements; however, mostly miss to approach marketing strategically. At the same time, they believe that they should make a better use of the possibilities provided by the digital media. Considering these results, we recommend that marketing education for craft producers should focus on conceptualising marketing as a process of interconnected decisions that go beyond promotion, and that when approached strategically help to make day-to-day market-related decisions simpler and more efficient. We also recommend that such education include practical knowledge of essential digital marketing techniques. The originality of the research lies in reaching conclusions about the future educational needs of craft producers by not only directly asking interested individuals about their needs, but also by going beyond and analysing descriptions of their marketing activities to better understand the full scope of their educational needs.

Winged-bean meal can serve as a substitute for soybean meal in plant-based fish feed, despite its trypsin-inhibitor properties, which can be alleviated through heating processes. This study aimed to explore the potential of winged-bean meal subjected to different heating methods, namely oven (110 °C for 30 minutes) and autoclave (121 °C for 30 minutes), based on proximate analysis and trypsin activity. The study applied three treatments with four replications: oven heating (O), autoclave heating (A), and control (without heating, E). All data were analyzed using analysis of variance and Duncan’s multiple range test to determine the best treatment. Data were also compared to the nutrient requirements of several cultured freshwater fish in Indonesia. Heating treatments improved in vitro trypsin activity (1300 units/O and 1135 units/A vs. 835 units) but reduced protein (29.05±1.96%/A and 31.73±1.52%/O vs. 35.17±0.38%) and moisture contents. Additionally, the O treatment met the standards for aquafeed protein content (27-45%) and potentially fulfilled the protein requirements for catfish (25-40%), Nile tilapia (30-35%), and Java barb (30-32%). Therefore, oven heating presents a viable candidate as an alternative plant-based aquafeed ingredient. Nevertheless, the in vivo application of winged-bean meal as an aquafeed ingredient should be further evaluated to determine whether heating treatment effectively enhances digestive activity, nutrient retention, and growth performance in target fish species.
Features of the introduced species composition and state in the arboreta of Dzhanybek research station in the Northern Pre-Caspian Semi-Desert
Authors: Sizemskaya M. L. , Sapanov M. K.
Published: July 2024

The results of studying introduced species diversity and state under rainfed conditions at the Research station of the Institute of Forest Science of the Russian Academy of Sciences have been presented. The station is located in the clay semi-desert of the Northern Pre-Caspian region between the Volga and Ural rivers. The collections of two arboreta were examined. The first arboretum was established in 1953 on hydromorphic meadow-chestnut soils of large mesodepressions, and the second – in 1974 on solonetzic automorphic soils. The arboreta were originally established with an idea of complete elimination of irrigation. In recent decades, tending and silvicultural treatments were discontinued for a number of reasons. An annotated list of tree and shrub species includes 77 species belonging to 25 families and 44 genus. In the arboretum on the large mesodepression, the number of species surviving for more than half a century is 35% in relation to the number of “core” introduced species. Mostly, the species are represented by the families Rosaceae, Caprifoliaceae, Elaeagnaceae, Fagaceae, Fabacea, Oleaceae, Salicaceae, Sapindaceae, Ulmaceae. Some specimens older than 70 years are in satisfactory condition and produce viable volunteer regrowth. The main stages of their acclimatization, in relation to age, and changes in growing conditions, as affected by plants themselves as well as climate, are distinguished. In arboretum on solonetzic soils, the survival of species is 50%. The composition of tree and shrub vegetation of an unused pond, where spontaneous vegetation formed an intrazonal willow-oleaster-poplar community of quasi-riparian type, and of the overgrowing fallow land, where a specific “savannah-like” landscape was formed, have been studied. This allowed to identify the species whose life strategy contributes to their successful colonization of human-disturbed habitats and, in some cases, manifestation of the features of naturalization and invasiveness. The most promising species for landscaping, parks and other plantings in such harsh natural and climatic conditions were also determined.

Представлены возможности методов ИК-спектроскопии и ИК-микроскопии с преобразованием Фурье для структурно-группового и распределительного анализа образцов осадочных пород на примере нефтяных сланцев баженовской свиты Западно-Сибирского нефтегазоносного бассейна. Результаты рассмотрены в сочетании с комплексом методов, применяемых в геохимическом анализе пород: программируемым пиролизом по методике Рок-Эвал, рентгенофлуоресцентным анализом и элементным CHNS/O-анализом. Показано, что метод ИК-спектроскопии можно использовать для структурно-группового анализа и оценки содержания органического вещества непосредственно в нефтематеринских породах. В исследуемых образцах керогенонасыщенных пород баженовской свиты содержание органического вещества хорошо согласуется с результатами пиролиза, а содержание алифатических фрагментов превышает содержание ароматических в 2.0–2.3 раза, что соответствует преобразованному керогену II типа. Метод ИК-микроскопии с преобразованием Фурье, известный как удобный неразрушающий метод анализа, предоставляет также возможность распределительного анализа органического вещества по пришлифованной поверхности образца с использованием цветного площадного картирования. На примере образцов баженовской свиты продемонстрированы неоднородность состава пород и неравномерное распределение органического вещества нетрадиционных коллекторов, что позволят эффективно использовать метод ИК-микроскопии в комплексе с другими методами исследования нефтематеринских пород.

On the Pauzhetka geothermal field the mineral deposits which are formed, when dumping thermal water of separators of wells, are allocated. Compositions, structure and geochemical properties of this precipitation on pro-deleting and in vertical slits of “raincoats” are studied. It is established that they are put X-ray amorphous mordenite – opal mixes (in the beginning dumping of thermal waters), further precipitation becomes completely siliceous. The zeolitic component of mineral deposits defines their high sorption properties in the relation of Au, Ag, Hg, As, Rb, Sr, Ba, Cs, etc. elements; in a mordenitovy matrix sulfides of iron, silver, copper are formed. It is shown that the mineral deposits which are formed on the day surface of the Pauzhetka geothermal field are the indicator of alkaline mineral- and the ore-forming processes on the lower horizons of the Pauzhetka hydrothermal system.

Authors: Gliga Constantin I.
Published: July 2024

We can define a tax inspection as the procedure by which the competent tax authority orders a tax inspection of a taxpayer. The hypothesis considered in this material mainly concerns the period of time during which the tax inspection can be carried out and, more importantly, the consequences to which the tax authority is subject in the event of failure to comply with the mandatory legal provisions concerning the maximum period of time during which the tax inspection can be carried out, given that this procedure can be suspended at the request of the tax authority to obtain additional information necessary for the control activity. Thus, this paper will take as a starting point brief considerations on how to conduct this procedure, taking as a point of reference the legislation in force at the time, following mainly the method of calculating the maximum duration in which the tax authority can conduct this procedure and the consequences of non-compliance with mandatory relevant legal provisions.

Preparing Accounting Students for Careers Utilizing Data Analytics: Curriculum Innovation Steps and Challenges
Authors: Pan Kevin , Mazzei Matthew
Published: July 2024

Data analytics has become increasingly important in the accounting profession. To prepare accounting students for careers that require data analytic skills, accounting departments in institutions of higher education need to integrate data analytics into existing curricula. While the curriculum development process has been described extensively in prior literature, adding data analytics to accounting curriculum proves challenging for several reasons, including the complexity of the subject of data analytics, insufficient faculty resources, and the limited credit hours accounting students have available for new courses. In this paper, we describe our business school’s seven-step process of incorporating data analytics into the accounting curriculum. Since analytics learning objectives cannot be taught within the accounting curriculum by accounting faculty alone, this curriculum innovation required collaboration with other faculty. This analytics curriculum update required buy-in from various stakeholders, all done despite notoriously limited time and resources. We were able to see accounting students succeed in their internships and careers using analytics learned from this new curriculum. In addition to describing the steps, we discuss the challenges faced and lessons learned from integrating accounting and analytics education.

Supreme Court Circular No. 3 of 2018 explains that cases of contested divorces that do not provide guarantees for the wife's rights after divorce are systematically Supreme Court Circular No. 3 of 2018 explains that cases of contested divorces that do not provide guarantees for the wife's rights after divorce are systematically confirmed by SEMA No. 2 of 2019, which explains the timing of alimony payments. In the Batusangkar Religious Court in 2022, there were five decisions on divorce cases challenging non-Nusyuz wives, but two decisions granted maintenance while three decisions did not grant them. Therefore, it is important to examine the legal considerations of judges when deciding divorce cases against non-Nusyuz wives and the considerations of judges when protecting the maintenance rights of non-Nusyuz wives at the Batusangkar Religious Court. The type of research is empirical legal research with a qualitative-descriptive approach. The judge's legal considerations in deciding contested divorce cases were that the fulfillment of the wife's post-divorce rights in the five contested divorce cases satisfied the formal and substantive legal aspects, although there were divergent opinions in the application of substantive law. The judge's consideration can be seen from the penalty paid before the defendant issued the divorce certificate and the defendant's financial ability, as well as the existence of a peace agreement between the plaintiff and the defendant. In cases where the payer of alimony is not determined for a wife who is not nusyuz after the divorce, the judge, on the other hand, takes into account that the defendant is financially unable, while in all cases the wording "can" is considered optional and is not interpreted as an optional imperative.

Implementing STAD cooperative learning model integrated interactive PhET simulation to enhance high school students’ learning outcomes: a case of momentum-impulse concepts
Authors: Aulia Ghiffary Zikry
Published: July 2024

This study aims to determine the effectiveness of STAD with the help of PhET interactive simulations in increasing student activity and learning outcomes and to find out the difference in improving student learning outcomes before and after the implementation of Student Team Achievement Division (STAD) cooperative learning with the help of PhET interactive simulations about momentum and impulse. This research was conducted because there are still many students who get unsatisfactory learning outcomes in physics subjects, because students think that physics subjects are difficult to understand. One of the reasons is that learning is dominated by the teacher so that students do not have the opportunity to exchange ideas. In addition, students need tools to get an overview of the material presented by the teacher. So that STAD learning with the help of interactive PhET simulation can help students to improve student learning outcomes. The research method used is a quasi-experimental design with a non-equivalent control group. Based on the Wilcoxon test, the Z value was obtained (Z=-2.532; p=0.11<0.05), the hypothesis was that there was a difference in the improvement of student learning outcomes between those using STAD learning with the help of PhET interactive simulation and conventional learning methods.

The level of understanding of students’ learning in studying physics material deserves attention so that things do not happen that are not in accordance with the realm of concepts set by experts. The concept of physics is indeed fun to learn but it is enough to make students feel difficult when learning every material concept. The cause is the abstract concept of physics and its complicated mathematical calculations, especially in the matter of momentum and impulses. Although several studies state that misconceptions in studying physics concepts can be overcome, they do not last long and will definitely happen again. Therefore, this study aims to identify misconceptions among high school students regarding the concept of momentum and impulse. The research method used is descriptive quantitative. The participants in this study were 37 students who were obtained using a purposive sampling technique. The instrument used is the Three-tier diagnostic test which is formulated based on the indicators contained in the school curriculum used. The research data were obtained from the results of an analysis of the answers and patterns of students’ answers on the three-tier diagnostic test items. The results of the study showed that it was identified that more than fifty percent of students had misconceptions.

Laboratory activities have the potential to enhance engagement through observation, experimentation, and active involvement. This study focuses on developing a solar cell experiment for junior high school students. The procedures involve measuring the dominant wavelength across various visible light spectrum and exploring the relationship between wavelength and the voltage and current output from a solar cell. The results indicate a negative correlation between wavelength and voltage/current. The highest recorded voltage and current, 1.75 V and 13.9 μA, respectively, were obtained at a wavelength of 400 nm. In contrast, the light with the highest wavelength, 650 nm, yielded the lowest recorded voltage and current, which were 1.43 V and 8.7 μA. Such laboratory activities can serve as valuable tools for teachers to impart the concept of wavelength and its real-world applications to students without the need for expensive or advance tools.
