La langostilla de río o cangrejo rojo americano (Procambarus clarkii) es una especie invasora que altera los ecosistemas y la calidad del agua, pues es portadora de organismos dañinos para la salud y, además, desestabiliza estructuras al remover materiales cuando cava sus madrigueras. El objetivo del presente estudio fue estudiar aspectos poblacionales, morfométricos y dietarios de P. clarkii en la dársena de la planta Tibitoc. Se hicieron tres muestreos utilizando en cada uno 120 trampas de tipo Zreal y Accesotech, cebadas con comida de gato durante 24 horas. Los resultados sugieren que la densidad fue baja (300 ind/ha), aunque el potencial de invasión puede ser alto debido a que las hembras llevaban más de 500 huevos. La proporción de sexos fue 1:1, y las hembras presentaron diferentes estados de maduración, lo que indica desoves consecutivos, y tenían mayor tamaño y peso que los machos. Los datos morfométricos de los especímenes recolectados y sus rasgos reproductivos registraron valores menores a los reportados en la literatura, lo que sugiere que los requerimientos alimenticios no eran adecuados y, probablemente, no se daban todas las condiciones para el desarrollo de la población. La dieta estuvo constituida por detritus, material vegetal, algas, macroinvertebrados y peces, lo que concuerda con lo informado en otros estudios. El tiempo estimado de vida media de P. clarkii fue de 2,3 años. Para controlar la población de esta especie en la dársena de la planta Tibitoc, se recomiendan capturas pasivas anuales con trampas Accesotech (o de diseño parecido).

Marketing of cities and regions. Identity, Image, Communication
Effective urban and regional marketing focuses on key aspects related to local development, including the competition of cities and regions for investors, residents, workers and tourists. Improving the image and proper promotion of a place’s unique characteristics attracts investment and new residents, which has a positive impact on economic growth and quality of life. The book also discusses the importance of effective image management, internal communication with residents, active community engagement and the use of online and mobile tools. In addition to an overview of theoretical issues built based on a review of domestic (Polish) and foreign scientific literature, the book includes the results of a survey conducted by the BioStat office. The survey was carried out using the CAWI technique on a representative sample of Polish people. The overall objective was to examine the relationship between the socio-demographic characteristics of respondents and their place of residence and their responses to individual questions related to the main idea of the study. The monograph is divided into six chapters that focus on important issues related to the identity and image of cities and regions, information and communication with residents in the local government unit, and communication of municipal/city authorities with residents.

Authors: Jacome Monserrath , Campodónico Nicolás
Published: August 2024

El abuso sexual cometido en contra de niños y niñas es una de las tantas formas de maltrato infantil y vulneración de los derechos humanos. Principalmente suele llevarse a cabo por personas cercanas a los infantes como lo son familiares y/o cuidadores, situación que ejerce un impacto devastador en los menores, lo que hace necesaria la aplicación de tratamiento psicológico para prevenir trastornos y mejorar su bienestar. La terapia cognitivo conductual focalizada en el trauma (TF-CBT, por sus siglas en inglés) cuenta con estudios de eficacia en diferentes formas de maltrato infantil. Con estos antecedentes, en el presente artículo se realizará una revisión sistemática sobre la eficacia de dicha terapia en el tratamiento psicológico del abuso sexual infantil, publicados entre el 2000- 2022 en español e inglés, en las siguientes bases de datos: PubMed, Psycnet de la APA, Scielo y Dialnet. La revisión de los estudios presenta evidencia consistente de que la TF-CBT es eficaz para tratar sintomatología asociada al abuso sexual infantil. Se discuten las categorías recurrentes de la eficacia de la mencionada terapia y a partir de ello, se concluye que los estudios proporcionan evidencia sólida sobre la eficacia de la TF-CBT.

Narratives of Agency: Understanding the Refugee Experience through Paintings at the EU’s External Borders
Authors: Osso Berfin Nur
Published: August 2024

Despite a burgeoning interest in the “visual” in migration and border research, refugees’ own perspectives of how they represent their experiences of struggles with/against borders through paintings remain underinvestigated. This article seeks to fill this gap by providing a close and contextual understanding of refugees’ perceptions and their first-hand experiences of their struggles with borders with reference to critical border studies and visual approaches. Drawing on qualitative analysis of the paintings produced by en route refugee artists at the Hope Project on the Greek island of Lesvos, the article dissects the emerging visual narratives and practices. The article exposes three common narratives from the paintings regarding how the artists recount the perilous journeys of refugees from home toward the European Union, their everyday life constrained in Lesvos, and their future aspirations in a tide of freedom and uncertainty. These common narratives illustrate a sense of continuity between the past, present, and future of refugees’ migratory and life trajectories interrupted by the European border(ing) regime. As the article illustrates, the paintings reveal how refugees as socio-political agents challenge the state borders built against their mobilities and, in doing so, they also defy the symbolic borders fabricated against their identities.
Despite a burgeoning interest in “visual” migration and border research, refugees’ own representations of their experiences of struggles with/against borders through paintings remain underinvestigated. In this article, I provide a close and contextual understanding of refugee perceptions and their first-hand experiences of struggles with borders, while highlighting the political significance of refugee-produced artworks in borderlands. Inspired by critical border studies and visual approaches, I draw on qualitative analysis of 70 paintings produced by en route refugee artists at the Hope Project on the Greek island of Lesvos, dissecting the emerging visual narratives and refugees’ creative practices. Analysis exposes three common narrative themes of the paintings: the perilous journeys of refugees from their homes toward the European Union, their everyday life constrained in Lesvos, and their future aspirations in a tide of freedom and uncertainty. These themes illustrate a sense of continuity between the past, present, and future of refugee experience, interrupted by the European border(ing) regime. These narratives reveal that even seemingly depoliticized spaces, namely art workshops and paintings, can become hyper-politicized, recounting how refugees as socio-political agents challenge the state borders constructed to manage refugee mobility and defy the symbolic borders targeting their identity and political subjectivity.

Purpose. Consider a system of differential equations with delay, which models a fully connected chain of m + 1 neurons with delayed synoptic communication. For this fully connected system, construct periodic solutions in the form of discrete traveling waves. This means that all components are represented by the same periodic function u(t) with a shift that is a multiple of some parameter Δ (to be found). Methods. To search for the described solutions, in this work we move from the original system to an equation for an unknown function u(t), containing m ordered delays, differing with step Δ. It performs an exponential substitution (typical of equations of the Volterra type) in order to obtain a relay equation of a special form. Results. For the resulting equation, a parameter range is found in which it is possible to construct a periodic solution with period T depending on the parameter Δ. For the found period formula T = T(Δ), it is possible to prove the solvability of the period equation, that is, to prove the existence of non-zero parameters — integer p and real Δ — satisfying the equation (m + 1)Δ = pT(∆). The constructed function u(t) has a bursting effect. This means that u(t) has a period of n high spikes, followed by a period of low values. Conclusion. The existence of a suitable parameter Δ ensures the existence of a periodic solution in the form of a discrete traveling wave for the original system. Due to the choice of permutation, the coexistence of (m + 1)! periodic solutions is ensured.

Authors:   Leading Research Scientist of the Department of Scientific Support for International Cooperation of the Prosecutor›s Office and Comparative Law, Chaschina Irina V.
Published: August 2024

Purpose. In the establishment and development of international tax relations, a key role is played by cooperation between States in the field of taxation, one of the most popular forms of implementation of which is the exchange of tax information. This form of international cooperation in the tax sphere is provided by a number of international treaties. Based on their analysis, as well as the study of Russian and foreign experience of their application in the implementation of cooperation in the field of taxation in the modern international environment, there is an urgent need to improve the agreements in this area in terms of organizing the exchange of tax information between the competent authorities of foreign countries. Methodology: dialectical, formal-legal, normative methods, method of comparative jurisprudence. Conclusions. The current international environment has a significant impact on international relations, which further complicates the already difficult process of international cooperation in the field of taxation. The way out of this situation is to deepen and further develop cooperation with the states seeking to comply with the agreements concluded with the Russian Federation in the tax sphere and thereby fulfill their obligations, as well as in improving these international treaties in terms of forms of international cooperation in combating violations of tax laws. Scientific and practical relevance. The conducted research allows to focus attention on the problems arising in the implementation of international cooperation in combating violations of tax laws, and as a consequence, the need to solve them by improving the legal regulation of such cooperation. The conclusions of this study can be used when amending or preparing international agreements in the field of combating violations of tax laws, as well as applied in the educational process when training specialists in this area.

ON THE CONCEPTUAL FRAMEWORKS OF LEGALITY AND LAW AND ORDER: THE THEORETICAL AND LEGAL ASPECT
Authors:   Associate Professor of the Department of Fundamental Jurisprudence and International Law, Akhmatov Aleksey V.
Published: August 2024

The paper examines the correlation between legality and law and order as fundamental legal categories from a theoretical perspective. It is noted that the concepts of legality and law and order are dialectically paired interrelated categories within the legal system. A distinctive feature of law and order is that it is not contingent upon the perception of law as a complex system of social order. Rather, it is the result of the activity and efficiency of the state mechanism in a particular historical period of its development. This concept determines the evolution of the state and law. It is a defining characteristic of a specific phenomenon within the realm of legal life. The author of the work posits that the concepts of legality and law and order require a novel interpretation in light of the advent of the post-classical stage of science. The author's interpretation of the content of these categories is made clear.

Towards temperature uniformity control: a process conditions selection chart
Authors: Veronesi Paolo , Colombini Elena , Leonelli Cristina
Published: August 2024

Processing conditions applied during microwave-assisted processes severely affects the final result, be it the yield of a reaction product or the microstructure of a determined heat treatment. Numerical simulation can help gather a deeper insight into microwave assisted processes, and by developing processing map, it can help selecting the optimum conditions to achieve the desired result. In this contribution we present the development of a process conditions selection chart, which can be used as a guideline to perform microwave synthesis with temperature-related objectives, like reaching the conditions of maximum or minimum temperature distribution homogeneity. Multiphysics numerical simulation of microwave heating at 2450 MHz in a TM010 single mode applicator of a liquid load, cylindrically shaped, was conducted by FEM setting a three way coupling of the electromagnetic field, the velocity field in the load and the thermal field. Results allow drawing a process condition selection chart useful for the synthesis of inorganic nanopowders, like TiO2.
Al-Sc Alloy Production using Metal Ion Plasma
Authors: Satoshi Fujii , Jun Fukushima , Yuya Okawa , Tomoaki Miyazawa
Published: August 2024

In chemical reactions using microwave irradiation, local concentration of electric and magnetic fields between particles, such as catalysts and powders, increases the reaction rate and lowers the temperature of the reduction reaction of the entire sample. The concentration of electric and magnetic fields between solid particles and plasma is believed to cause such reactions. In high-temperature reactions between individual particles, plasmas are directly involved in and accelerate chemical reactions, whose reaction temperatures reportedly become lower than the reduction reaction temperatures under normal heating. Therefore, using a cylindrical cavity in the TM110 mode at 2.45 GHz with a strong magnetic field, a Mg plasma was generated from Mg rods, and ten pellets of the Φ13×5 mm sample mixed with scandium oxide and aluminum powder were placed in an induction coil at 13.56 MHz and were reduced at 700 °C for approximately 1 h, with a conversion rate of 42%. Despite the low conversion rate, scandium oxide was successfully reduced at a low temperature by Mg plasma and induction heating without necessitating the use of additional solvents. The low conversion rate was caused by an insufficient supply of Mg, which could be resolved by increasing the reaction time. This experiment confirmed that Mg ions contribute to the lower temperature of the reduction reaction and that the generation of a Mg plasma by microwaves and the heating of the reaction zone by radiofrequency bands offer the prospect of fabricating a system larger than that obtained using microwaves alone.

Congenital heart defects (CHD) are the most common form of congenital malformations in children. Due to early diagnosis, rapid development of cardiac surgery technologies as well as successes in the care of severe patients after surgical correction of CHD, the survival and life expectancy of patients with CHD have significantly increased over the past decades. All this has led to the emergence of new population of patients with severe CHD and unique cardiac hemodynamics due to palliative intervention or multi-stage correction with large amount of exposure. Such patients have specific functional capabilities, special cardiopulmonary performance as well as the risk of serious adverse events (heart failure, life-threatening cardiac arrhythmias, sudden cardiac death and others).

The review presents generalized current understanding about the possibilities of a cardiorespiratory test in children with various CHD.

Do Double Taxation Avoidance Agreements Attract Foreign Direct Investment? The Case of Nepal
Authors: Chalise Bishal
Published: August 2024

Countries sign double taxation avoidance agreements (DTAs) to promote bilateral economic activities, and facilitate cross-border investment and capital transfer. Given the importance that countries place on DTAs to promote economic relations, this research aims to determine the impact of DTAs on foreign direct investment (FDI) in Nepal from 1990 to 2020. The research uses qualitative and quantitative approaches for the assessment. The paper estimates the average treatment effect of treatment using synthetic difference-in-difference (SDID) with a staggered adoption design. The design is appropriate for two key features in the given setting: (i) tax treaties are signed and come into effect at different times (years); and (ii) many countries without DTAs with Nepal have invested in the country. This can be used to construct the appropriate counterfactuals.
Crafting a Model for Taxing Digital Financial Services
Authors: Wales Christoher , Niesten Hannelore
Published: August 2024

The taxation of mobile money (MM) and other digital financial services (DFS) is a multifaceted and evolving issue. It has become a significant concern and source of controversy over the last decade. As yet, there is no universally accepted standard approach to taxing DFS, but the complexity of the issues underscores the need for a clear and holistic framework. While much has been written about tax and DFS, direct guidance to policy-makers is scarce; other than, perhaps, to avoid taxing them at all (GSMA 2023a, 2023b; Vodafone 2023). In this policy brief we aim to fill that gap, and offer some brief but specific thoughts about how a tax regime for DFS might be constructed, drawing on experience from the DIGITAX research programme. We do not claim that our model is comprehensive, or that the evidence base for it is complete, but we believe it is preferable to leaving a vacuum in policy guidance.

Phylogeographic structuring within recently diverged scorpion species, Euscorpius borovaglavaensis Tropea, 2015 (Scorpiones: Euscorpiidae) in Croatia, with the description of a new subspecies

The European scorpion Euscorpius borovaglavaensis Tropea, 2015 is a morphologically cryptic species that is distinguishable only with difficulty from E. tergestinus (C. L. Koch, 1837). It is distributed in the middle part of the Dinaric Alps chain and along part of the Eastern Adriatic coast, specifically, in Croatia (Middle Dalmatia, Lika karst upland), as well as in the southern part of Bosnia and Herzegovina. The new findings reported here have enhanced our knowledge of its geographic distribution in Croatia. Detailed morphological analyses highlighted the importance of carination in the ventral metasomal segments as morphological traits. Phylogenetic analyses, based on the mitochondrial cytochrome c oxidase subunit I (COI) gene, have revealed the existence of two distinct lineages. One of them, distributed in the northwestern part of the range, is described here as E. b. flavus n. ssp., while the nominal subspecies occurs in the southeastern part. A time-calibrated phylogenetic analysis has established their divergence around 0.9 million years ago, coinciding with the Mid-Pleistocene Transition (MPT) period. In contrast to the nominal subspecies, E. b. flavus n. ssp. exhibits significant phylogeographic structuring, indicating recent isolation events in multiple glacial microrefugia after the initial divergence, followed by a final Holocene dispersal in the northwestern direction deep between the mountain chains.
