In Lake Baikal, the number, diversity, and structure of femtoplankton – bacteria passing through filters with a 0.2 μm pore size – were studied for the first time using a complex of methods. The bacterial abundance in the femtoplankton fraction was 7×104 cells/mL in the 0-50 m water layer, as measured by epifluorescence microscopy, and their contribution to the total bacterial number reached an average of 4.4%. High-throughput sequencing of 16S rRNA gene fragments revealed a significant genetic and taxonomic diversity of femtobacterioplankton in the pelagic and littoral zones of the lake. Dominant and minor phyla, orders, families, genera, and phylotypes of bacteria were identified in two fractions of Lake Baikal bacterioplankton: larger and smaller than 0.2 µm. We determined the contribution of ultra-small bacteria to the taxonomic composition of microbial communities in different parts of the lake. The microbiomes of bacterioplankton and femtobacterioplankton fractions differed significantly, and we described the peculiarities of ultramicrobacteria composition. The results demonstrated an important role of ultra-small bacteria in Lake Baikal’s ecosystem.

With the rapid development of microorganism biodiversity estimation and community profiling via DNA metabarcoding, there is a growing need to identify key stages affecting the results of experiment. In order to ensure high-quality reproducible results, all potential sources of bias should be explored. While bioinformatic pipelines can be often corrected and optimized to recalculate results, the initial steps of sample collection procedure, potentially influencing the downstream results of bacterial community profiling, are much harder to correct easily, without repeating the whole experiment. We examined the differences of the amplicon bacterial community profiles generated from aquatic microbial communities captured by polycarbonate (PC) and cellulose acetate (CA) filters. The microbial community profiles were shown to be significantly different by biodiversity. When using a PC-filters, alpha- and beta-diversity of communities were significantly higher. Differential abundance analysis showed enrichment of major cyanobacterial OTUs in CA-treated communities. Based on these results, the use of PC-filters is the most optimal for bacterial community profiling by metabarcoding of the 16S rRNA gene fragments.

The paper presents the results of a study of the reasons for the formation of biofilms during the purification of groundwater with use of natural sorbents. Analysis of the microbial complexes structure at different stages of water treatment showed that their numbers increased after filtration through a load with granular activated carbon. In some cases, it remained high in storage tanks containing purified water. In fact, at all stages of water treatment, representatives of Actinobacteria were found in the community structure, which formed biofilms in the technical system, as well as after 14 days of storage in bottled water. It was established that representatives of actinomycetes in the planktonic state formed flakes from mycelium, and on filter media they formed biofilms in the form of a complex structured community. Actinobacteria strains isolated from water and activated carbon biofilms differed in their cultural and morphological characteristics. However, they were characterized by a common ability to produce polymeric substances that formed a protective matrix and promoted cell adhesion to various substrates and surfaces. Scanning electron microscopy shown that sporulation promoted survival during all stages of groundwater treatment, including chlorination and ozonation.

CORRELATION AND REGRESSION ANALYSIS OF THE IMPACT OF ECONOMIC GLOBALIZATION ON THE DEVELOPMENT OF NATIONAL MARKETS
Authors: Флегантова Анна , Романюха Дар’я
Published: September 2024

The study of consequential relations between economic globalization and the number of subsidiaries of leading TNCs revealed that their development largely depends on the country's involvement in the globalized space. Correlation analysis confirmed the existence of a relationship between TNCs and GDP, which is the main macroeconomic indicator that reflects the participation of countries in export-import operations. Analysis by industry confirmed that economic globalization contributes to the growth of TNCs through increased GDP, regardless of the type of goods and services. On the contrary, TNCs can also have a positive impact on GDP, supporting the scale of economic globalization. Regression analysis and construction of regression models revealed the specifics of the impact of economic globalization on the development of TNCs in countries with different socio-economic conditions. This specificity consists in differences in the influence of one set of factors on the number of foreign branches of TNCs in countries with different levels of development. This confirms the controversy of the phenomenon of economic globalization and indicates that the growth of TNCs is possible only in countries with high indicators of economic globalization. The development of countries is asymmetric, so the spread of globalization processes is also uneven, which indicates the different response of economies to their influence.

Massive Transformative Purpose (MTP) as moderator in the relationship between Culture of Experimentation and Autonomy
Authors: Vizcaíno Antonio de Jesús , Aguilar Ruiz Alfredo
Published: September 2024

The present research seeks to measure the relationship between the culture of experimentation and autonomy and the relationship between both variables when moderated by the organization's massive transformative purpose (MTP). This quantitative and exploratory research was conducted through a questionnaire for decision-makers in 43 medium and large IT companies in Jalisco. The results reveal a significant positive relationship between the culture of experimentation and autonomy, corroborating the first hypothesis of this research. However, according to the analyses to calculate the degree of moderation of the massive transformation purpose variable (moderator variable) to adjust the relationship between the culture of experimentation and autonomy, the results showed that there are no significant relationships, which rejects the second hypothesis of this research.

This research focuses on understanding the factors influencing the acceptance of entomophagy in Morelia, Michoacán. The study involves a survey aimed at two distinct groups of young adults aged 18 to 29 (control and experimental), a demographic known for being open to evolving food preferences. The results revealed interesting differences in preferences between individuals who have and have not tried insect-based foods. Surprisingly, the price did not emerge as a dominant influencing factor. The study suggests entomophagy can be a viable and accepted dietary option when relevant information is easily accessible, potentially reducing neophobia levels.
Genetic adaptation to climate change: a systematic literature review identifies opportunities to strengthen empirical studies of wild populations

To understand to what extent evolution can contribute to bending the curve of ongoing biodiversity losses, we urgently need to characterize what determines the adaptive potential of populations. We argue that capitalising on existing examples of genetic adaptation to climate change provides the opportunities to fill this major knowledge gap. We performed a systematic literature review and obtained 40 empirical examples of species with direct evidence of wild populations undergoing genetic adaptation in response to climate change selection. Only two of these examples (crustacean Daphnia magna and plant Brassica rapa) presented robust evidence for genetic adaptation driven by climate change, using strong inference methods to show that (1) a phenotypic change over time occurred, (2) the phenotype has a genetic basis, (3) the fitness of the phenotype depends on a climatic variable, (4) climate change-induced selection occurred across generations, and (5) it was assessed to what extent the genetic change involved a response to selection compared to the contribution of other evolutionary processes. There thus are ample opportunities to strengthen the evidence base for these existing examples such that they can contribute to understanding when and how genetic adaptation to climate change can take place. Moreover, improving the spatial and temporal replication of these existing studies is highly needed to identify general principles across species and populations. Especially genomics studies using high-resolution temporal sampling provide important information about the process and rate of evolution, but the field currently lacks such high-resolution temporal genomics studies. We urge the field to capitalize on and strengthen these existing examples of genetic adaptation so that we can identify which drivers and constraints determine the likelihood and rate of evolutionary responses to climate change.

Forests play a crucial role in regulating the global climate. Yet, forests also influence the local climate conditions through biophysical processes that directly impact human wellbeing. With growing policy emphasis on these climate adaptation effects, we review the scale dependent impacts of forests on climate conditions and their implications for human wellbeing. Generally, existing forests buffer local temperatures, with warming effects in cold regions and cooling effects in hot regions. At a global scale, trees are more conducive to cooling in regions where dense forests would naturally exist. Additionally, forests generally reduce water runoff, which can reduce flooding in wet areas, but it can also limit water availability downstream, especially in drier regions. Together, these findings suggest that climate positive tree effects tend to be most frequent in regions where forests naturally occur, and highlight the growing consensus around the importance of natural forests for climate adaptation.

All aspects of human life have been influenced by digital transformation, which has become a global trend ( Bangsawan, 2023 ). In Indonesia, policies that can accelerate digital transformation can accelerate economic growth, especially in the creative economy sector. To accelerate the existing transformation, infrastructure, literacy and regulation are existing problems. faster digital transformation in the development of Indonesia's creative economy. Studies show that policies that encourage digital transformation can encourage the growth of the creative economy in Indonesia, but they need to be adapted to local conditions and followed by efforts to increase the accessibility of adequate infrastructure and technology. Efforts to address existing challenges, such as improving technological accessibility and adequate infrastructure, could be part of this. Therefore, to encourage and support creative economic growth through policy, industry players, government and society must work together. accelerate the digital transformation process.

Organizational Communication Based on Local Wisdom by the Tourism Awareness Group in the Management of Cireundeu Traditional Village
Authors: Simanjuntak Diana , Sunarja Darmawan
Published: September 2024

Visiting tourist villages has become an alternative tourism trend favored by both domestic and international tourists. This trend is driven by tourists’ desire to gain new experiences and discover unique and distinctive natural and cultural attractions. Cireundeu Traditional Village is an increasingly visited destination, especially by students, university students, and academics. The management of these tourist villages is based on community involvement, known as Community-Based Tourism (CBT), where the participation of the local community is essential. This research aims to explore and analyze how the organizational communication of the Pokdarwis (Tourism Awareness Group) is carried out with mentors, fellow administrators, and the community in the context of managing the Cireundeu Traditional Village. The research seeks to identify communication patterns, obstacles, and the effectiveness of the communication strategies implemented. This study uses a qualitative approach with a case study design. Data was collected through participatory observation and in-depth interviews with members of the Pokdarwis, mentors, administrators, and local community members. Data analysis was conducted thematically to identify key patterns and themes in organizational communication based on local wisdom. The results show that Pokdarwis’ organizational communication is mostly acquired autodidactically. They can effectively understand and implement organizational communication functions and flows based on local wisdom. The Pokdarwis can communicate vertically, horizontally, and diagonally with mentors, fellow administrators, and the community. They can also express ideas and views, inform, empathize, and coordinate in the management of the Cireundeu Traditional Village. The organizational communication behavior of the Pokdarwis is based on local wisdom communication traditions, which include the principles of mutual learning, caring, nurturing, and sharing. It also involves relational foundations such as compassion for others, respect for lineage, etiquette, courteous behavior, and self-control.
A Novel Path-Following Method for Time-Varying Optimizations with Optimal Parametric Functions

Published: September 2024

We address a broad category of nonlinear constrained optimization problems. We then reformulate it as a time-varying optimization using continuous-time parametric functions and derive a dynamical system to track the respective optimal solution. We then re-parameterize the dynamical system according to a linear combination of parametric functions. By applying the calculus of variations, we optimize these parametric functions to minimize the optimality distance. Consequently, we develop an iterative dynamic algorithm, termed as OP-TVO, to achieve efficient convergence to the solution. We compare the performance of the proposed algorithm with the prediction correction method (PCM) in terms of optimality and computational complexity. The results demonstrate that OP-TVO effectively competes with PCM for the given class of optimization problems, suggesting a promising alternative to PCM. This work also introduces a novel paradigm for solving parametric dynamic systems.
