Employment management system for universities based on improved decision tree
Authors: Li Jing , Ma Yongsheng 
Published: July 2024

Abstract
With the popularization of higher education, the number of students in colleges and universities is increasing, and how to timely cope with the various problems faced by students in employment has become a major problem faced by teachers in colleges and universities. Due to the low utilization rate of student information by the traditional employment management of college graduates, the quality of employment guidance services is not high. Therefore, to solve this problem, this study proposes a simplified, improved Iterative Dichotomizer 3 (ID3) based on the correlation coefficient, and the algorithm improves the information gain function and simplifies the information entropy formula. The experimental results show that the simplified modified ID3 based on correlation coefficients converges faster than the other two algorithms, starting to converge after only 17 iterations; the loss value is also smaller than the other algorithms, at around 0.12. Its minimum accuracy, precision, recall, and F1-measure for employment status prediction were 86.4, 76.8, 72.8, and 0.82%, respectively, all higher than the rest of the algorithms. The time complexity at a sample size of 80 is only 32 ms, which is lower than the rest of the algorithms. It can be seen that the simplified and improved ID3 based on correlation coefficients can accurately and efficiently perform predictive analysis of graduates’ employment status. The university employment management system proposed in the study has achieved efficient deep utilization of graduate information through ID3, providing assistance to university employment decision-makers and reference for employment guidance for university graduates.
Religiosität und Delinquenz unter christlichen und muslimischen Jugendlichen
Authors: Steinmann Jan-Philip 
Published: July 2024

Zusammenfassung
Der Beitrag untersucht den Zusammenhang zwischen Religiosität und Jugenddelinquenz für christliche und muslimische Jugendliche und hinterfragt die Annahme einer negativen linearen Verknüpfung beider Konstrukte aus früherer Forschung. Stattdessen wird vermutet, dass eine delinquenzreduzierende Wirkung von Religiosität nur bis zu einem gewissen Grad an Religiosität vorhanden ist und sich anschließend in eine delinquenzsteigernde Wirkung verkehren sollte, sodass insgesamt von einer u-förmigen Beziehung zwischen Religiosität und Jugenddelinquenz auszugehen ist. Zur Untermauerung dieser Vermutung werden theoretische Perspektiven vorgestellt, die einerseits eine delinquenzreduzierende (soziale Kontrolle, Lernprozesse, Umgang mit Belastungen) und andererseits eine delinquenzsteigernde Wirkung von Religiosität (Fundamentalismus, wahrgenommene Benachteiligung) plausibilisieren. Basierend auf einer Befragung von Jugendlichen der neunten Jahrgangsstufe an niedersächsischen Schulen aus dem Jahr 2022 wird das Vorliegen einer u-förmigen Beziehung zwischen Religiosität und Jugenddelinquenz überprüft. Empirisch zeigt sich, dass zwischen Religiosität und Gewaltdelikten eine kurvilineare, zwischen Religiosität und Eigentumsdelikten jedoch eine lineare Verknüpfung besteht. Diese Befunde gelten sowohl für christliche als auch muslimische Jugendliche. Abschließend werden die Verallgemeinerbarkeit der Ergebnisse sowie die Limitationen des Beitrags diskutiert.

RESEARCH STRATEGIES OF EXILED NARODNIKS IN THE SIBERIAN ETHNOGRAPHY IN THE SECOND HALF OF 19TH – EARLY 20TH CENTURY
Authors: Ледовских А.Ю. , Кебак Т.А. 
Published: July 2024

В статье рассматриваются исследовательские стратегии ссыльных народников, занимавшихся этнографическими проблемами в Сибири во второй половине XIX – начале XX в. На основе мемуарных текстов, переписки и материалов научных работ «невольных поселенцев» охарактеризована специфика постановки ими научных целей и задач. Особое внимание обращено на раскрытие мотивации, вовлекавшей ссыльных народников в изучение населения восточного региона, их теоретической и практической подготовки к научным исследованиям. Кроме того, затрагиваются особенности организации экспедиций с учетом ограниченности прав политических ссыльных, сложностей во взаимодействии с представителями имперской администрации на разных ее уровнях, освещаются трудности с публикацией народниками результатов своих научных исследований.
Ethnographic research in the Russian Empire experienced its heyday in the second half of the 19th century and the beginning of the 20th century, and multiple ethnographers emerged from among the exiled Narodniks during this rise. Their research activities attract special attention because of the contrast between their lack of specialized, and more often even complete higher education, and the successes in science that they managed to achieve. In recent years, the study of the experience of exiled Narodniks as ethnographers has intensified in the fields of intellectual history and the history of ethnography, but their research strategies have not yet become the subjects of special study. Turning to the texts of the memoirs of ethnographers-Narodniks and other political exiles, as well as their articles in specialized magazines and published correspondence, the present article tries to answer the question of how they solved their research tasks without the appropriate basic theoretical and practical training. Considering that the Narodniks were not professional researchers and were spontaneously involved in the study of the indigenous population, special attention is paid to their research motivation, which was not limited to the need to conduct at least some kind of intellectual activity in the conditions of the exile. The success of the “involuntary ethnographers” has led to the attention to the resources they had at the beginning of their research, including full everyday involvement in the life of Siberian indigenous people and knowledge of at least one local language. The authors focused on the transition from “spontaneous” to organized ethnographic research, the difficulties that arose at the stage of organizing the expeditions and the nuances associated with the processing and publication of the gathered materials.

Benih ikan baramundi Lates calcarifer diperoleh dari pemijahan alami dengan jumlah induk terbatas sehingga variabilitas pertumbuhan dan kelangsungan hidup antar-batch menjadi tinggi. Penelitian dilakukan untuk menganalisis pertumbuhan dan mengevaluasi variasi genetik ikan kakap putih populasi Australia, Situbondo dan Lampung hasil domestikasi dan dibudidaya di hatcheri skala rumah tangga (HSRT). Sebanyak 10 ekor ikan barramundi dari setiap populasi digunakan untuk analisis variabilitas genetik dengan dua lokus mikrosatelit, yaitu Lca21 dan Lca32. Selanjutnya, data mikrosatelit diolah menggunakan software genetic analysis in excel (GenAlEx 6.51b2). Hasil yang diperoleh menunjukkan bahwa pertumbuhan panjang dan bobot tubuh serta laju pertumbuhan spesifik ikan baramundi dari Australia lebih tinggi dibandingkan dari Situbondo dan Lampung (P<0,05); sedangkan ikan baramundi dari Situbondo dengan Lampung adalah sama (P>0,05). Jumlah alel setiap lokus ikan baramundi berkisar 2-8 alel dan heterozigositas tertinggi dimiliki oleh ikan barramundi asal Situbondo (0,85), diikuti Lampung (0,65) dan paling rendah dari Australia (0,54). Dari hasil riset tersebut dapat disimpulkan bahwa ketiga populasi ikan baramundi hasil domestikasi dan dipeliharan dalam sistem HSRT memenuhi kelayakan untuk digunakan untuk kegiatan hibridisasi atau membentuk populasi awal (sintetis). Barramundi seeds, Lates calcarifer are usually sourced from natural spawning using a limited number of broodstock. Therefore, the growth and survival rate of these seeds vary greatly between batches. The research was performed to determine the growth pattern and genetic variations of barramundi seed populations produced from domesticated broodstock sourced from Australia, Situbondo, and Lampung and reared in small-scale hatcheries. Ten individuals of barramundi from each population were used for microsatellite analysis using two microsatellite loci, namely: Lca 21 and Lca 32. The resulted microsatellite data was processed using the genetic analysis available in Excel software (GenAlEx 6.51b2). The results showed that the growth in length and body weight as well as the specific growth rate of barramundi seeds produced from Australia broodstock were higher than that of Situbondo and Lampung (P<0.05) while the later two were similar (P>0.05). The number of microsatellite alleles ranged from 2-8 and the highest heterozygosity was obtained by barramundi seeds produced by Situbondo (0.85), followed by Lampung (0.65), dan Australia (0.54) broodstock. From the results of the research, it can be concluded that the three populations of barramundi fish, which were domesticated and reared in the HSRT system, meet the criteria for use in hybridization program or for forming a synthetic population.

Bakteri Edwardsiella tarda yang menginfeksi ikan patin dapat menyebabkan kematian hingga 80%. Terong asam (Solanum ferox) mengandung senyawa antibakteri yang dapat menghambat pertumbuhan bakteri dan dapat membunuh bakteri penyebab infeksi. Tujuan penelitian adalah untuk mengetahui pengaruh ekstrak S. ferox terhadap respons imun ikan patin jambal (Pangasius djambal) serta memperoleh dosis optimum untuk penanggulangan bakteri E. tarda. Metode yang dilakukan adalah eksperimen dengan rancangan acak lengkap (RAL) dengan empat perlakuan dosis ekstrak terong asam (0, 300, 600, dan 900 ppm) serta kontrol (perendaman antibiotik komersial) dengan tiga ulangan. Ikan uji yang digunakan adalah ikan patin jambal berukuran 14-16 cm sebanyak 150 ekor. Perlakuan diberikan dengan perendaman ikan uji dalam larutan uji selama 7 hari. Parameter uji antara lain gejala klinis, total eritrosit, total leukosit, diferensial leukosit, aktivitas fagositosis, prevalensi, pertumbuhan bobot mutlak, dan kelangsungan hidup. Hasil penelitian menunjukkan bahwa perendaman ikan patin jambal dalam larutan ekstrak S. ferox meningkatkan respons imun ikan patin jambal yang terinfeksi E. tarda.. Hasil penelitian ini menyimpulkan bahwa ekstrak S. ferox dosis 600 ppm secara efektif meningkatkan aktifitas fagositosis yang kemudian mengoptimalkan respons imun dan profil darah ikan patin jambal. Infection of Edwardsiella tarda bacteria in farmed catfish could lead to mass mortality of up to 80% of the fish. Sour eggplant (Solanum ferox) contains antibacterial compounds which are capable of inhibiting the growth of bacteria and can kill infectious bacteria. The study aimed to determine the effect of S. ferox extract on the immune response of catfish (Pangasius djambal) and obtain its optimum dose to control the infection of E. tarda. The study used an experimental trial in which treatments were arranged in a completely randomized design (CRD) consisting of four treatment doses of sour eggplant extract (0, 300, 600, and 900 ppm) and control (immersion of commercial antibiotic) with three replicates. The test fish used were 150 catfish with a length of 14-16 cm. The treatments were applied by soaking the test fish in the test solutions for 7 days. The measured parameters included clinical symptoms, total erythrocytes, total leukocytes, leukocyte differential, phagocytic activity, prevalence, absolute weight growth, and survival. The results showed that the immersion of catfish in S. ferox extract solution increased the immune responses of catfish infected by E. tarda. The results of this study concluded that S. ferox extract at a dose of 600 ppm effectively increases phagocytic activity which then optimizes the immune response and blood profile of catfish.

Authors: Григорьева Ирина Андреевна , Видясова Людмила Александровна 
Published: July 2024

Статья посвящена наукометрическому анализу публикаций, охватывающих проблематику активного старения/долголетия, отложенного старения и здоровья пожилых людей. Целью работы является поиск новых исследовательских методов для изучения многофакторного и нелинейного характера старения, а также выявление связи тематической наполненности научных публикаций с ключевыми направлениями, заявленными в официальной повестке Мадридского международного плана по активному старению и Индексе активного старения. Утверждение концепции активного старения через мадридский план и последующие национальные планы активного старения / долголетия в ряде стран выступило важным нормативным ориентиром для жизни в позднем возрасте. Это не только способствовало политике длительной занятости пожилых, но и оказало важное влияние на изменение общественного восприятия старения, жизненной стратегии и самоидентификации пожилых. В России «Стратегия действий в интересах граждан старшего поколения в Российской Федерации до 2025 года», принятая в 2016 г. с «осторожными» формулировками, и Индекс активного долголетия (ИАД) стали важными шагами на пути адаптации к глобальным трендам в области старения. В статье анализируется предметное поле научных публикаций по теме активного и отложенного старения, а также поздней взрослости в контексте взаимосвязи с критериями ИАД. Результаты тематического картирования научных публикаций освещают как отечественный, так и зарубежный опыт исследований в этой области. Исследование выявило преобладание тем, связанных с разработкой критериев для оценки активного старения и долголетия, человеческого капитала, а также вопросов здоровья и использования сервисов здравоохранения. Также отмечается тенденция к медикализации исследований проблем старения и акцент на аналитических методах обработки больших данных.

Abstract

Emerging evidence suggests pericytes play a significant role in various lung diseases. However, characterizing pericytes remains challenging, impeding our understanding of their role in lung development and disease. Using single-cell RNA sequencing and DCM-time machine technology, we tracked the development of mouse pulmonary pericytes. Our study revealed the differentiation of perivascular progenitors into pericytes and vascular smooth muscle cells. Temporal analysis uncovered dynamic gene expression profiles during pericyte differentiation, highlighting pathways crucial for pulmonary vascular development. Further analysis showed intricate signaling interactions between pericyte progenitors and mature pericytes, and we validated Mcam as a bona fide pulmonary pericyte marker. These findings challenge conventional views on pericyte origin and underscore the importance of accurate pericyte identification in developmental and disease contexts. Overall, this study enhances our understanding of pulmonary pericyte ontogeny and differentiation, offering insights into their potential as therapeutic targets in pericyte-associated lung diseases.
A study on the influence of digital literacy on the participation of rural middle-aged and elderly people in digital life: Moderating Effect based on Intergenerational Support

Published: July 2024

Abstract

Based on the micro-survey data of 669 rural middle-aged and elderly people in Shandong Province, this paper explores the impact of digital literacy on the digital life participation of rural middle-aged and elderly people by constructing the evaluation index system of digital literacy, and further tests the moderating effect of intergenerational support on the relationship between digital literacy and digital life participation of rural middle-aged and elderly people. The study shows that the digital literacy and intergenerational support of the middle-aged and elderly people in rural areas are generally low, and the degree of digital life participation is low. Digital literacy has a significantly positive impact on the digital life participation of rural middle-aged and elderly people, and intergenerational support also has a positive impact on it, and intergenerational support has a positive moderating effect on the relationship between digital literacy and the digital life participation of rural middle-aged and elderly people. The impact of digital literacy and intergenerational support on digital life participation varies among different rural middle-aged and elderly groups. Among them, the younger the age, the higher the education level, the higher the personal income, and the occupation of the new agricultural business subject in rural middle-aged and elderly people, the greater the impact of digital literacy and intergenerational support on their digital life participation. Therefore, it puts forward some suggestions such as improving the digital education and cultivation system for the middle and old people, vigorously carrying out digital general education for the middle and old people, strengthening the intergenerational support for children, and promoting the transformation of digital life software for aging.
Plant Community Analysis in Embahasti Remnant Forest, Southern Tigray, Ethiopia
Authors: Gidey Mebrahtu Hishe 
Published: July 2024

Abstract

Tigray is one of the most environmentally degraded regions in Ethiopia left with remnant natural vegetation. The purpose of this study was to assess the plant communities of Embahasti remnant forest in southern Tigray, Ethiopia. Vegetation data were collected from 40 sample quadrates placed in transect lines, which were systematically laid. All vascular plant species including herbs, shrubs, lianas, and trees in each quadrat were recorded. Hierarchical cluster analysis and Canonical Correspondence analysis (CCA) performed that used for plant community analysis. Shannon-Wiener diversity Index was also computed for ecological data analysis. All the above analysis was performed using R 3.4.1 version software. A total of 74 plant species belonging 44 families were found in the study area; shrubs and trees (70.27%) species were dominant. Solanaceae, Fabaceae and Lamiaceae were the dominant families in terms of species. Three plant communities identified from the forest, namely Olea europaea subsp. Cuspidata – Juniperus procera, Myrsine africana – Erica arborea, Acacia abyssinica – Dodonea angustifolia. The highest Shannon-wiener diversity index was 3.26 while the least was 2.29 found in community one and three, respectively. Altitude, Slope, Grazing and human impacts are the factors influencing species distribution. It is, therefore, based on the results of this study, detailed ecological studies in relation to various environmental factors such as soil type and properties, ethnobotanical studies to explore indigenous knowledge on the diverse uses of plants, and sound management and monitoring as well as maintenance of biodiversity that promote sustainable use of the forest is recommended.
