Published: June 2023

The digital era is exposing the media industry and the audience to a new phenomenon, it is convergence. Convergence becomes a real challenge have to be faced by the entire media industry, from global to local media industries. The convergence faced by local media is a bigger challenge due to limited financial and resources. Various studies show that adaptation is mostly done by utilizing platforms in new media to re-embrace segmentation and even add new audience segmentations. The forms of adaptation presented show the elements of branding media in it. According to Malmelin and Moisander (2014) there are five concepts of branding media that are often used, they are brand extension, brand as identity, brand as differentiation, brand as equity, and brand as a product. This article will show the side of branding media by the local Javanese language magazine "Panjebar Semangat" in the middle of adaptation efforts to convergence. The discussion will be related to the five concepts presented by Malmelin and Moisander (2014). The method used in this research is descriptive qualitative. Data collection was carried out by interview and observation on the Panjebar Semangat social media account. The results show that the branding media activities carried out by Panjebar Semangat are dominated by the concept of brand extension and brand as a product. The branding media can also give well benefit by local media with limited funding sources to optimize adaptation to convergence.

Published: June 2023

Palm oil liquid waste or waste processing CPO (Crude Palm Oil) commonly called CPO (Crude Palm Oil) trenches are very potential to be processed into biodiesel. At the moment, CPO (CPO trenches) processing waste is only considered as waste that pollutes the environment and is not of economic value. If left continuously, palm oil liquid waste that has a pH of 4.2 (acidic) will cause problems for the environment if disposed of directly. One form of utilization of CPO trenches that can be done is by converting it into biodiesel. The manufacture of biodiesel from CPO trenches uses transesterification reactions such as the manufacture of biodiesel in general, with pretreatment to lower the acid figures in the CPO trenches. Biodiesel was obtained later in the analysis of quality standards based on SNI 04-7182-2006 and obtained results that meet the requirements for four parameters, namely the content of FFA samples before the transesterification process is 1.82%. Tan biodiesel content of 0.3055 mg KOH/g. The content of free glycerol is 0.0198% and the total glycerol is 0.0884%.

Lo ilegible en las obras de Leónidas Lamborghini y Juan José Saer
Authors:   , Pastoriza Malena
Published: June 2023

Esta investigación se ha propuesto dar cuenta de lo ilegible en y de la literatura de Leónidas Lamborghini y Juan José Saer, en su vínculo con las escrituras críticas e historiográficas que la tomaron como objeto. La tesis parte de la identificación de una consonancia en el proceso de recepción de la literatura de Saer y Lamborghini: una primera etapa de ilegibilidad vinculable con cierto grado de novedad y singularidad de sus primeros textos, ajenos e incluso contrarios a las expectativas dominantes en esos años; y su contraste con un segundo momento, hacia comienzos de los ochenta aproximadamente, luego de más de dos décadas de producción y publicación ininterrumpidas, en que sus obras comienzan a ocupar un lugar central en el mapa de la literatura de la época, sus nombres son incluidos en los programas universitarios de literatura argentina y sus libros figuran entre los más leídos por sus contemporáneos. En este escenario, el objetivo de la investigación fue interrogar cómo el problema de lo ilegible en las obras de Saer y Lamborghini ha intervenido en los modos de concebir la relación entre los procedimientos formales de la literatura y el proceso histórico de su recepción en el contexto específico de la literatura argentina de las décadas del sesenta, setenta y ochenta. Es decir, sostenemos la productividad de no clausurar la pregunta por si la ilegibilidad es un rasgo literario o una figuración crítica, y apostamos, en cambio, por explorar la tensión que se establece entre ilegibilidad histórica e ilegibilidad retórica en las diversas perspectivas que han guiado la práctica crítica dedicada a las obras de Saer y Lamborghini.

Investigating Effects of Perceived Technology-enhanced Environment on Self-regulated Learning: Beyond P-values
Authors: Sui Chi-Jung , Yen Miao-Hsuan , Chang Chun-Yen
Published: June 2023

This study examined the effects of a technology-enhanced intervention on the self-regulation of 262 eighth-grade students, employing information and communication technology (ICT) and web-based self-assessment tools set against science learning. The data were analyzed using both maximum likelihood and Bayesian structural equation modeling to unravel the intricate relationships between self-regulation, self-efficacy, perceptions of ICT, and self-assessment tools. Our research findings underscored the direct and indirect impacts of self-efficacy, perceived ease of use, and perceived use of technology on self-regulation. The results revealed the predictive power of self-assessment tools in determining self-regulation outcomes, underlining the potential of technology-enhanced self-regulated learning environments. The study posited the necessity to transcend mere technology incorporation and to emphasize the inclusion of monitoring strategies explicitly designed to augment self-regulation. Interestingly, self-efficacy appeared to indirectly influence self-regulation outcomes through perceived the use of technology rather than direct influence. Analytically, this research indicated that Bayesian estimation could offer a more comprehensive insight into structural equation modeling by more accurately assessing our estimates' uncertainty. This research substantially contributes to comprehending the influence of technology-enhanced environments on students' self-regulated learning, stressing the importance of constructing practical tools explicitly designed to cultivate self-regulation.

Initial functions of lactoferrin were due to the fact that it is very similar to transferrin, iron binding protein, whose key role in providing iron to developing erythrocytes was already known. Iron is an extremely important element for the development of not only macroorganism, but also microorganisms. The aim of the study was to evaluate the antimicrobial efficacy of the use of various forms of lactoferrin in relation to experimentally modeled polyvid microbial consortia of an odontogenic nature. According to the results of the conducted studies, it was shown that this protein has a pronounced bacteriostatic effect, and has an inhibitory effect against various types of microorganisms with varying degrees of severity. Conclusion. All the samples under study have a clear bacteriostatic effect, and with an increase in the dose, signs of a bactericidal tendency are noted, which allows us to consider them as promising for the creation of dosage forms for dental practice.
On the exploitation of a population given by a system of linear equations with random parameters
Authors: Woldeab M.S. , Rodina L.I.
Published: June 2023

We consider a population whose dynamics in the absence of exploitation is given by a system of linear homogeneous differential equations, and some random shares of the resource of each species at fixed times, are extracted from this population. We assume that the harvesting process can be controlled in such a way as to limit the amount of the extracted resource in order to increase the size of the next harvesting. A method for harvesting a resource is described, in which the largest value of the average time benefit is reached with a probability of one, provided that the initial amount of the population is constantly maintained or periodically restored. The harvesting modes are also considered in which the average time benefit is infinite. To prove the main assertions, we use the corollary of the law of large numbers proved by A.N. Kolmogorov. The results on the optimal resource extraction for systems of linear difference equations, a particular case of which are Leslie and Lefkovich population dynamics models, are given.
Asymptotic expansion of the solution to an optimal control problem for a linear autonomous system with a terminal convex quality index depending on slow and fast variables
Authors: Danilin A.R. , Kovrizhnykh O.O.
Published: June 2023

In this paper, we investigate a problem of optimal control over a finite time interval for a linear autonomous system with slow and fast variables in the class of piecewise continuous controls with smooth geometric constraints in the form of a ball. We consider a terminal convex quality index that depends on slow and fast variables. We substantiate a limit relation for the vector determining the optimal control as the small parameter tends to zero. We refine the limit relation for the case of an indirect control problem with a terminal quality index, which is the sum of values of two strictly convex continuously differentiable functions, the first of which depends only on slow variables, and the second one depends only on fast variables and has a minimum at zero. In doing so, we show that the first component of the determining vector converges to the determining vector of the limit problem while the second component tends to zero. In the problem of indirect control of a system of material points in a medium with resistance, we obtain the complete asymptotics of the determining vector in powers of a small parameter.
Algorithms for constructing suboptimal coverings of plane figures with disks in the class of regular lattices
Authors: Lebedev P.D. , Kuvshinov O.A.
Published: June 2023

The problem of covering a compact planar set $M$ with a set of congruent disks is considered. It is assumed that the centers of the circles belong to some lattice. The criterion of optimality in one case is the minimum of the number of elements of the covering, and in the other case — the minimum of the Hausdorff deviation of the union of elements of the covering from the set $M$. To solve the problems, transformations of parallel transfer and rotation with the center at the origin can be applied to the lattice. Statements concerning sufficient conditions for sets of circles that provide solutions to the problems are proved. Numerical algorithms based on minimizing the Hausdorff deviation between two flat compacts are proposed. Solutions of a number of examples are given for various figures of $M$.
Differential game with “lifeline” for Pontryagin's control example
Authors: Samatov B.T. , Soyibboev U.B.
Published: June 2023

The main purpose of this work is to solve one of the main problems of Isaacs, i.e., a game with a “lifeline” for Pontryagin’s control example when both players have the same movement dynamics. To solve this problem, the pursuer is offered a strategy of parallel pursuit (briefly, $\Pi$-strategy), which ensures the fastest convergence of the players and the capture of the evader within a certain closed ball. In addition, for the differential game under consideration, an explicit analytical formula for the players' attainability domain is given and the main lemma is generalized (L.A. Petrosjan's lemma on monotonicity of the players' attainability domain with respect to embedding for a game of simple pursuit). Using this main lemma, we find conditions for the solvability of the game with a “lifeline” for Pontryagin's control example as well. For clarity, at the end of the work, examples are given for some special cases.
Tracking evolutionary dynamics within the fungal wheat pathogen "Zymoseptoria tritici"
Authors:   , Bellah Hadjer
Published: June 2023

Plant pathogenic fungi are very widespread and can pose severe risks to global food production through single as well as mixed infection. Crop control is based on the use of synthetic chemicals and plant resistance breeding. However, fungal plant pathogens quickly overcome both strategies. During coinfections, plant pathogens can increase disease severity and change co-infecting genotypes virulence evolution. Hence, monitoring tools improving crop pathogen detection as well as understanding the impact of co-infection events on disease severity are lacking. Additionally, we still lack information on the genetic basis shaping virulence and fungicide resistance evolution over time. In this PhD thesis I focused on developing monitoring tool to track virulence and fungicide resistance evolution in the fungal wheat pathogen Zymoseptoria tritici using different molecular and genomic tools. Here I designed a microfluidics-based amplicon sequencing assay to multiplex several loci targeting virulence and fungicide resistance genes, and randomly selected genome-wide markers. More than hundred types of samples were used to assess the performance of our assay. This later allowed an accurate amplification of all designed loci and performed well regardless of the sample type. I also explored the outcomes of mixed interactions within and outside the plant host by using a large sample size to provide a deeper picture about the consequences of such interactions on disease severity as well as virulence and growth effects. I found that the growth kinetics and virulence in single interactions deviated from those seen during mixed interactions indicating competitive exclusion between conspecific strains. Additionally, the outcomes were divergent within and outside the plant host indicating that the plant immune system plays a key role in shaping the within-plant interaction outcomes and adds significant complexity. Finally, I used a data set of worldwide populations of Z. tritici to investigate transposable elements (TEs) located nearby important virulence and fungicide resistance genes allowing to retrace the evolutionary history of the pathogen worldwide as well as a better crop protection strategies. I identified a considerable number of TEs belonging to different families and superfamilies, I also detected recent insertions represented by unique insertions called singletons. Overall, this PhD thesis allows monitoring newly evolved Z. tritici genotypes and understanding the genetic basis mediating their adaptation to their hosts and environment. Besides, the thesis provides information about the consequences of mixed interactions on disease severity and how these can shape change in virulence and growth of plant pathogens.
Spatially balanced sampling, stratification and statistical matching
Authors:   , Jauslin Raphaël
Published: June 2023

In this thesis, we are interested in three fields of sampling theory. These three fields are spatial sampling, stratification and finally statistical matching. After the first chapter recapitulating the main notions of sampling theory, the thesis comprises two parts, each containing two chapters. The first part deals with spatial sampling. Particularly in the environmental sector, it is important to select a well-spread sample. The populations we study are often auto-correlated, i.e. two units close to each other share the same characteristics and should not be selected in the same sample. In the second chapter, we propose a method to select a very well-spread sample. The third chapter proposes a method to select a sample that is both spread on geographical coordinates and balanced on auxiliary variables. This method has the particularity of being sequential, which offers a wider scope of application, especially in very large datasets. The second part of the thesis discusses stratification and statistical matching. In a survey, the estimator is almost always improved by separating the population into subgroups when this information is available. These subgroups can be large or small depending on the characteristics of the variables that condition them. The fourth chapter proposes an algorithm for drawing a balanced sample in highly stratified populations. Finally, the fifth chapter discusses statistical matching, which consists in merging two surveys. We use the optimal transport problem to combine the two surveys into a pseudo-population that allows conclusions to be drawn on variables measured only in each of the respective surveys.

Netizens upload the keyword "Mixue" on Twitter, which can become an electronic word of mouth (E-WoM). E-WoM is one of the dominant factors influencing purchase demand for a product. Using the keyword "Mixue" to become a trending topic creates a communication network to disseminate information related or not to Mixue. This study aimed to determine the distribution of the "Mixue" network as a medium for electronic word of mouth using Social Network Analysis (SNA). The theory used is computer-mediated communication. The research method is quantitative with the SNA approach. Researchers crawled data on 10,000 tweets on December 27, 2022, when the keyword "Mixue" became a trending topic. The researcher used the application. The results showed that the "Mixue" communication network involved 7,702 actors and 8,391 conversations. @handokotjung became an important actor after posting a humorous tweet about Mixue's expansion in Indonesia. The tweet achieved 3.3 million views, 2,277 replies, 13.6K retweets, 2,682 excerpts retweeted, and 67.5K likes. The other actors also got into the conversation regarding Mixue. The perpetrators communicate with each other by replying, retweeting, retweeting quotes, or uploading their tweets, which can be electronic word-of-mouth (E-WoM) media accessed by anyone without exception. Mixue can use social media and impoertant actors to increase people's buying interest in Mixue
