Heuristic decision making selection of drone models according to specified characteristics
Authors: Afonin V. V. , Nikulin V. V. 
Published: April 2024

Objective. The noticeable interest in aircraft such as drones for various purposes puts forward certain requirements for their characteristics. Characteristics can be divided into information technology and consumer characteristics from a financial point of view. At the same time, they have their own units of measurement. In this regard, the task of selecting and ranking drones according to some criterion or numerical metric arises. Considering that this problem is quite relevant, this paper considers a certain heuristic approach to sorting a sample of drones by the key of the proposed metric.Method. In the heuristic approach, there is a certain variability in determining the attractiveness of a particular drone in the opinion of the person making the decision to purchase or a specific choice from the existing line of drones available for review based on their characteristics.Result. It is proposed to identify several groups in the existing characteristics, heterogeneous in their properties, both obvious and intuitively created: “good”, “very good”, “less attractive”, “least attractive”. Assuming that several models of drones with the same characteristics are being considered, divided into the specified groups, numerical coefficients are introduced to form a metric by which a given line or selection of drones will be ranked according to the calculated metrics.Conclusion. The proposed heuristic algorithm is based on the transition to the reduced values of numerical characteristics relative to the maximum of each group of characteristics with the calculation of the arithmetic mean of the given values. Depending on the type of specified groups, the coefficients entered into consideration are added or subtracted from the difference between the current characteristic and its average or the difference between the average and the current characteristic. On this basis, metrics are calculated by which the given sample of drone models is ranked.

Abstract
Tourism livelihood has become an essential livelihood decision for people to get rid of poverty. Under the background of the internet era, it is of great significance to study how ethnic village farm households can participate in tourism livelihood with the help of information capacity. Applying the Resource Orchestration Theory and taking Guolan Yao Village in Jiangyong County of Hunan Province as an example, this paper uses binary logistic regression model and fuzzy set qualitative comparative analysis method to explore the mechanism of farm households’ information capacity affecting their tourism livelihood. The findings are as follows: Firstly, in addition to financial capital, other livelihood capital and information capacity have a significant impact on farm households’ participation in tourism livelihood. Secondly, when financial capital is lacking, farm households in ethnic villages with information capacity can unite with human capital, social capital, natural capital or physical capital to make up for the non-existent defect of financial capital and help realize tourism livelihood. Thirdly, when human capital is lacking, farm households in ethnic villages with information capacity can make up for the absence of human capital by combining natural capital, financial capital and social capital to help realize tourism livelihood.

Abstract
With the dynamic and complex changes in the farmers’ living environment and the vigorous development of entrepreneurial activities worldwide, farmer entrepreneurship is experiencing rapid growth. However, whether farmer entrepreneurship enhances the welfare of farmers’ families demands further scrutiny. Utilizing data from the Chinese Family Tracking Survey and drawing on Amartya Sen’s capability approach, this article formulates a farmer family welfare evaluation index system to comprehensively assess the impact of farmer entrepreneurship on farmer families. The research findings reveal the following: (1) Entrepreneurship contributes to enhancing the welfare of farmer families, with entrepreneurial farmer families experiencing higher welfare levels than their non-entrepreneurial counterparts. (2) Farmer entrepreneurship falls short of delivering complete welfare improvements to farmers’ families. While various welfare conditions, such as family economics, social security, living conditions, and psychological conditions, have improved after starting a business, health welfare has seen a decline. (3) Farmland transfer significantly influences the process of farmer entrepreneurship, directly fostering the family welfare of entrepreneurial farmers. (4) Farmers’ entrepreneurial behavior yields greater welfare benefits for the new generation, farmers with higher education levels, and those situated in the central region. Building on these findings, this study proposes relevant improvement suggestions to offer robust support for policy considerations.

Student metacognition only focuses on individuals, not yet associated with student positioning in the group. There are positioning groups whose roles change, so it is necessary to examine more deeply the characterization of students' metacognition in solving multiplication problems in group discussions in terms of student positioning. This study aims to describe students' metacognitive activities, students' roles during the discussion process, and students' metacognitive abilities related to students' roles during group discussions on multiplication material in mathematics of grade 6 students in one of the public elementary schools in Indonesia. Not only knowing the concept so that students can think critically and learn independently from students without teacher assistance, but also students must be trained in solving problems. This study used descriptive qualitative as the research method. It was found that awareness was mainly found in expert and facilitator positions, regulation was found in expert and facilitator students, and evaluation was found in all student roles. The metacognitive characteristics that emerged in group discussions were expert students as triggers (stimulus) and regulators (contribution), facilitator students as regulators (contribution) and followers (passive), and novice students as followers (passive).Metakognitif siswa hanya berfokus terhadap individu, belum dikaitkan dengan pemosisian siswa dalam kelompok. Ada kelompok pemosisian yang perannya berubah, sehingga perlu mengkaji lebih mendalam terkait karakterisasi metakognitif siswa dalam menyelesaikan masalah perkalian pada diskusi kelompok ditinjau dari pemosisian siswa. Penelitian ini bertujuan untuk mendeskripsikan aktivitas metakognitif siswa, peran siswa selama proses diskusi, dan kemampuan metakognitif siswa yang terkait dengan peran siswa selama diskusi kelompok pada materi perkalian matematika siswa kelas 6 di salah satu sekolah dasar negeri di Indonesia. Tidak hanya mengetahui konsep agar siswa dapat berpikir kritis dan belajar secara mandiri dari siswa tanpa bantuan guru, tetapi juga siswa harus dilatih dalam memecahkan masalah. Penelitian ini menggunakan deskriptif kualitatif sebagai metode penelitian. Ditemukan bahwa kesadaran terutama ditemukan pada posisi ahli dan fasilitator, regulasi ditemukan pada siswa ahli dan fasilitator, dan evaluasi ditemukan pada semua peran siswa. Karakteristik metakognitif yang muncul dalam diskusi kelompok adalah siswa ahli sebagai pemicu (stimulus) dan pengatur (kontribusi), siswa fasilitator sebagai pengatur (kontribusi) dan pengikut (pasif), dan siswa pemula sebagai pengikut (pasif).

Desa Medalsari memiliki potensi alam dan budaya yang merupakan modal untuk menjadi desa wisata. Upaya mengarah pada pembentukan desa wisata pernah terjadi, namun karena kualitas sumber daya manusia yang masih kurang dan diperparah oleh pandemi Covid-19 membuat belum bisa terwujud. Oleh karena itu, sebagai langkah awal tim Pengabdian Pada Masyarakat (PPM) melakukan program pengambangan toponimi sebagai daya dukung wisata di Desa Medalsari. Program tersebut dilaksanakan dalam dua kegiatan, yaitu penyuluhan mengenai toponimi sebagai refleksi budaya masyarakat Medalsari berdasarkan hasil penelitian yang dilakukan sebelumnya, dan workshop pengembangan toponimi melalui aplikasi Google Maps dan Local Guide. Program PPM ini diselenggarakan pada bulan Juni-Agustus 2022 dan dilakukan dalam 4 tahap yaitu seleksi lokasi, sosialisasi pemberdayaan masyarakat, proses pemberdayaan masyarakat, dan pemandirian masyarakat. Setelah mengikuti program PPM, para peserta mengungkapkan dengan antusias bahwa mereka lebih mengetahui asal-usul nama tempat di wilayah mereka karena beberapa nama tempat tidak diketahui asal-usulnya. Mereka pun lebih mengetahui Google Maps dan manfaatnya untuk menyimpan nama kampung masing-masing setelah mendaftar diri dalam aplikasi Local Guide. Pendampingan dan pembinaan dari akademisi sangat dibutuhkan masyarakat untuk mengembang desa dan meningkatkan taraf hidup masyarakatnya. Medalsari Village has natural and cultural potential which needs to be utilized to become a tourist village. Efforts to lead to the formation of a tourist village have occurred, but due to the lack of quality human resources and exacerbated by the Covid-19 pandemic, this has not been realized. Therefore, as a first step, the Community Service Team (PPM) carried out a toponymy development program as a tourism support in Medalsari Village. The program was implemented in two activities, namely counseling on toponymy as a reflection of the culture of the Medalsari community based on the results of previous research, and a toponymy development workshop through the Google Maps and Local Guide applications. The PPM program is held in June-August 2022 and is carried out in 4 stages, namely location selection, socialization of community empowerment, community empowerment process, and community self-reliance. After participating in the PPM program, the participants enthusiastically expressed that they know more about the origins of place names in their area because the origins of some place names are unknown. They also know more about Google Maps and its benefits for saving the names of their respective villages after registering in the Local Guide application. Assistance and guidance from academics is needed by the community to develop the village and improve the standard of living of the community.

Published: April 2024

Abstract
Honey bee workers (Apis mellifera L.) collect nectar, honeydew and pollen from plants in orderto provide the colony with, among others, carbohydrates and protein. Whenever these sources are unavailable in the environment, bees turn to alternatives. An example of this are fungi spores collected accidentally or on purpose. This last phenomenon is the aim of this study, in which we have shown that worker bees can collect willow rust (Melampsora spp.) spores. We observed as the bees obtained spores and placed them in pollen baskets. The presence of spores was demonstrated with the use of a scanning electron microscope (SEM). This observation indicates that the honey bee may use alternative sources as a potential supplement. There are few studies in this field and it requires a deeper analysis.
Forschungs-, Technologie- und Innovationspolitik muss die Entstehung kritischer Massen fördern
Authors: Schubert Torben , Kroll Henning , Blind Knut , Frietsch Rainer 
Published: April 2024

Abstract
Economic research emphasises the role of increasing returns to scale and critical mass in research and technology development. This suggests that countries benefit from specialising in certain technologies and can thereby bundle available resources. Using the example of the Exzellenzstrategie and the Zukunftsstrategie, we argue that German RTI policy lacks strategic prioritisation. The lack of focus implies that Germany spreads its resources too thinly over many technological alternatives and therefore fails to create critical mass within each of them. The guiding principles for a German RTI policy should focus on creating critical mass through specialisation..

Published: April 2024

Abstract
The year 2022 was characterised by extraordinary social and economic pressures. Russia’s war against Ukraine led to major energy policy and economic upheaval, high inflation and the challenge of taking in refugees from Ukraine. At the same time, the statutory minimum wage was increased twice in 2022 from 9.82 € to 10.45 € in July and to 12 € per hour in October. With regard to this significant increase in a difficult economic environment, many questions arise: How many and which firms were affected by the minimum wage increases in 2022? How severely were these establishments affected by the war in Ukraine? What are the challenges they are currently facing?

Authors: Al-Shebli Abdullah , Alhajri Thafar M 
Published: April 2024

Objective: This article was produced due to the ongoing debate about the protection of minority shareholders in listed companies. It details the challenges faced by minority shareholders and sets out the various methods scholars have identified that can be used to protect minority shareholders.
However, some lawmakers believe that cumulative voting is a substantial improvement in the methods commonly used to protect minority shareholders. The article considers what cumulative voting is, how it differs from straight voting rights and what benefits it provides, particularly for minority shareholders. Furthermore, the article considers the effectiveness of cumulative voting as a means of protecting minority shareholders from majority shareholders and delinquent boards of directors.

Method: In writing this article, the authors compared the approach used in various countries to protect minority shareholders. They analysed the information gathered in a comparative study process to ascertain the international best practice relating to protecting minority shareholders and cumulative voting rights. At the end of this process, the article concludes with a review of the international best practices and how these may be applied in Kuwait.

Result & Conclusion: After considering the theory behind cumulative voting and the application thereof, the conclusion reached is that cumulative voting does not adequately protect minority shareholders. Furthermore, the Kuwaiti legislature has not made cumulative voting mandatory and, as a result, few, if any, companies have adopted this method of voting.
