Venezuelai válság: az olajexport múltja és jövőbeli kilátásai
Authors: Füzesi Kitti
Published: March 2023

Venezuela tekintélyes nyersanyagtartalékokkal rendelkezik, ennélfogva – figyelembe véve Földünk továbbra is növekvő energiafogyasztását – a világpolitikában is fontos szerepet tölthetne be. A dél-amerikai ország gazdaságát teljes mértékben az olajiparra alapozta, emiatt a világpiaci árváltozások igen érzékenyen érintették. Az 1980-as évek végén nemzetközi hiteleket kellett felvennie, jelenleg pedig hiperinflációval, humanitárius válsággal küzd. Az egyre romló gazdasági helyzet az olajiparra is kihatott, az infrastruktúra állapota is rosszabbodott. A cikk bemutatja az olaj kitermelésének történetét és vizsgálja a jelenlegi válsághoz vezető okokat, a jövőbeni lehetőségeket.

Objectives: Children aged 10 to 12 years often show dangerous maneuvers during landing, which include increased knee valgus, placing them at higher risk of anterior cruciate ligament (ACL) injuries. The study aimed to investigate the relation of the trunk and hip kinematics with the peak knee abduction angle during single-leg landing among preadolescent female soccer players. Methods: Thirty-six preadolescent female soccer players aged 10 to 12 years attended the study. Participants did a static trial and after that performed landing trials. A single-leg landing was applied to assess the landing kinematics. A three-dimensional motion capture system was applied to analyze trunk, hip, and knee kinematics. Results: Pearson correlation coefficient demonstrated a significantly positive relationship between peak hip internal rotation angle (r=0.361) (P=0.03) and peak knee abduction angle. Furthermore, no significant relationship was identified between peak hip adduction (r=-0.102) (P=0.55), peak trunk rotation (r=0.239) (P=0.16), peak trunk lateral flexion (r=0.052) (P=0.76), and peak valgus knee. Discussion: Peak hip rotation angle was correlated with the valgus knee with a weak correlation value among preadolescent female soccer players. Future studies should consider kinematic risk factors related to ACL injuries in combination with neuromuscular control trunk and hip during more demanding tasks.

Objectives: In 1998, the Persian form of Language Assessment, Remediation, & Screening Procedure (P-LARSP) was introduced. However, this adapted version remained on library shelves and was not used by Iranian speech and language pathologists (SLPs). The present study aimed to explore the barriers to using P-LARSP, resolve the possible issues, and provide a preliminary grammatical sketch from typical children aged 2-5. Methods: The study started with two surveys in two different populations to find the possible barriers and then, continued with the cross-cultural adaptation of the LARSP through international guidelines (forward and backward translations, cognitive interviewing, and pretesting). Finally, by the new P-LARSP, 120 language samples obtained from children (aged 2-5) in a free-play context were analyzed and data were processed in SPSS software, version 21. Results: Our surveys showed that Iranian SLPs had little familiarity with the P-LARSP, and they found it unclear, and difficult to understand the framework. While most of the participants recognized the P-LARSP as a relevant framework to analyze language samples, few numbers of participants used the P-LARSP with clinical or research aims. Through cross-cultural adaptation, a simple, clear, relevant, comprehensive, and applicable Persian profile along with a published manual was obtained and introduced to the SLPs through social media, workshops, and national congresses. Quantitative and qualitative analysis of 120 language samples showed grammatical structures have significant changes by age in terms of numbers and varieties of clauses, phrases, inflectional morphemes, and general syntactic indices. Discussion: The present study revealed why the P-LARSP remained unknown. We removed the barriers by introducing a new version of P-LARSP fully in Persian and increasing its simplicity, clarity, and understandability with a proper manual. Introducing the new version through proper channels to the target population was another taken step to increase the familiarity of the Iranian SLPs. In addition, the preliminary data indicated that the new P-LARSP with its manual is applicable to the language samples taken from typically developing children.

Methods: This study is descriptive-correlational modeling with partial least squares. The statistical population included singleton children of the sixth grade of the elementary school in the 3rd District of Tehran in the academic year 2017-18. The sampling method was multi-stage sampling; eight schools (four all-boys and four all-girls) were randomly selected from all primary schools in the 3rd District of Tehran, then, a sixth-grade class was randomly selected in each school. The singleton students of those classes participated in the present study as the study sample. The sample size was 118 students (81 girls and 37 boys). The instruments of this research included the Persian forms of adaptive and aggressive assertiveness scales (AAA-S), the Baumrind parenting scale, Beck anxiety inventory (BAI), and Rosenberg self-esteem scale (RSES). To analyze the data, the SPSS software, version 26. Results: The results indicated that authoritative and permissive parenting styles had a significant effect on assertiveness among the parenting styles. The total effects indicated that authoritative and permissive parenting styles explained 0.22 and 0.20 of the variances of assertiveness. The results also showed that the authoritarian parenting style had no significant effect on assertiveness. Discussion: The suggested model was acceptably fit, according to the results of the study. Permissive and authoritative parenting styles had impact on assertiveness.

Objectives: As a major feature of the disease, motor-related complications, including loss of balance and reduced ability to walk were seen in multiple sclerosis (MS). The purpose of this study was to investigate the effect of core stability exercises and transcranial direct-current stimulation (tDCS) as a non-invasive brain stimulation on balance, walking capacity, and quality of life in patients with MS. Methods: In this randomized clinical trial study with a pretest-posttest design, 29 female patients with an Expanded Disability Status Scale (EDSS) of less than 4.5 (3.75±1.31) and a mean age of 38.36±7.99 years were purposefully selected from patients referring to MS society of Tehran during 2021 and then randomly assigned to the following three groups: core stability exercises, anodal tDCS, and sham. Variables, such as balance, walking capacity, and quality of life were measured before and after the interventions. Subjects in the core stability training group participated in core stability exercises for three weeks, and subjects in both sham and anodal tDCS groups received direct brain electrical stimulation for five sessions. Results: A significant improvement in balance and walking capacity were seen both in the anodal tDCS and the core stability training groups (P<0.05). Moreover, mobility was significantly changed in the tDCS group (P<0.05). However, no significant difference in the quality of life was seen between the groups. Discussion: Our findings indicate comparable effects of tDCS, and core stability training on balance and walking capacity in patients with MS. Therefore, in addition to exercises, tDCS can be considered a promising tool for the neurorehabilitation of patients with MS.

Objectives: Chronic low back pain (CLBP), along with physical limitations that affect the quality of life, is one of the most important problems in the health community. The pain causes a wide range of structural, functional, and neurological changes in the brain. However, these changes have not been well studied, as brain changes in other chronic pains. This study aimed to evaluate the changes in the electroencephalogram (EEG) of patients with nonspecific CLBP, and also to evaluate the effects of interferential current (IFC), as one of the common treatment methods in these patients, on the EEG. Methods: This randomized control trial was performed in the Physiotherapy Clinic of Rehabilitation Faculty of Tabriz University of Medical Sciences from July 2021 to February 2022. A total of 20 patients with nonspecific CLBP and 20 healthy individuals participated in this study. Healthy subjects were in the control group, and the patients were randomly divided into two groups: intervention and placebo. Participants’ EEG and pain intensity were recorded before and after one session of IFC. Results: The results of statistical analyses to compare the EEG of patients and healthy individuals did not show a significant difference between the two groups. The results of statistical tests to evaluate the effects of IFC on participants’ EEG showed a significant increase in alpha frequency in all three groups. In addition, a significant increase in theta frequency was recorded in the placebo group, and an increase in the beta frequency in the intervention group. Pain intensity showed a significant decrease only in the intervention group. Discussion: The results of this study suggest that changes in EEG in patients with low back pain may be related to the severity of pain and neurological involvement. In addition, the increased power of EEG following the application of IFC may be due to sensory stimulation of the skin surface.

Possibilities of using micronucleus analysis to detect gene mutations in animals
Authors: Novgorodova I. P.
Published: March 2023

Relevance. The main purpose of micronuclear analysis is to identify substances that cause cytotoxic damage and lead to the formation of micronuclei containing lagging fragments of chromosomes or whole chromosomes. For the study of chromosomal disorders, micronuclear analysis is now very often used, since it is quite easy to perform and does not require large costs.

Methods and results. Micronuclei are cytoplasmic chromatin-containing bodies formed when delayed in anaphase or telophase during cell division or fragmentation of the nucleus during apoptosis. The method of micronuclear analysis is used as a biomarker of chromosomal aberrations in the study of mutagenicity, as well as a marker of the development of oncological diseases. With quantitative changes in DNA in the cell, the formation of micronuclei occurs. It is their presence that is an indicator that the body was exposed to environmental pollution (pesticides, pesticides, radiation, heavy metals, etc.), leading to inflammatory and pathological processes. Recently, many studies have been conducted aimed at studying the influence of environmental factors on the genetic apparatus of the body. Under the influence of mutagens, micronuclei are formed in proliferating cells, the counting of which allows for the diagnosis of both genotoxic stress and genetic instability of the organism. To determine early genetic changes in humans and animals, sensitive and labor-intensive methods are needed, which can be attributed to micronuclear analysis. Recently, micronuclear analysis has become relevant for its use in the livestock sector, mainly in research aimed at quality control of livestock products used in the future for human nutrition.

Relevance. Hybridization of pigs is one of the main factors in the production of high-quality pork, since such animals combine the genotype of the grandparent and parent breeds and, due to the effect of heterosis, have a high growth rate, improved meat qualities compared to purebred ones. The paper presents an assessment of the reproductive qualities of large white sows and the productive qualities of young animals obtained as a result of industrial two-pedigree crossing.

Methods. To implement the scientific and economic experience, 3 groups of sows of pairs-analogues of the Large White breed from the Hypor company (KB Hypor) were formed. Sows of the 1st group were crossed with Landrace boars from PIC (Landrace Pic), 2nd – with Landrace boars from Genesus Genetics (Landrace Genesus), 3rd – with Landrace boars from Hypor (Landrace Hypor).

Results. According to the results of the research, it was found that the multiple pregnancy of sows in groups 1st and 2nd was higher by 7.7%, and the number of stillborn piglets, on the contrary, was lower by 0.6 heads than in group 3. The weight of the nest of piglets at birth in the 1st and 2nd experimental groups was higher by 9.9 and 6.1%, respectively, in comparison with analogues from the 3rd group. In the hybrid young animals obtained during the experiment, an increase in the absolute, average daily and relative gain in live weight was noted.
Search for additional variability in the herd of Holstein cows
Authors: Popov N. A.
Published: March 2023

Relevance. When breeding a large herd of the Holstein breed, the improvement of traits in the selection system is reflected, the integral basis (part of the basis) of which was belonging to the line. Against the background of a reduction in the number of lines, the selection of a limited number of sires related to each other into the herd, and the breeding of daughters from them by various types of rebounds, an increase in milk yield and mass fraction of protein (MPF) over three generations is reflected.

Methods. The indices of the genetic value of sires in the population were evaluated according to the author's method, while taking into account the indicators of mothers and peers of the same herd. Comparison of the levels of variability of milk productivity traits in terms of standard deviations (±s) in breeding groups.

Results. The relative increase in milk yield per generation for the highest lactations was 8.9–15.4% (P < 0.001), and MDL – 1.3–3.2% (P < 0.01). A comparison was made of groups of peer-daughters obtained by targeted selection of homo- and heterozygous fathers according to genetic markers of controlled EAB loci. Another aspect was the high standard deviation of milk yields in the group of daughters of homozygous fathers by 19% against the group of heterozygous, and among the crossed offspring – by 8.6% against intraline. It is assumed that this happened due to the introduction of new and rare alleles with sires into the herd.

Published: March 2023

The article discusses various biopositive technologies for handling bituminous waste based on roofing materials after the loss of their operational properties. The processes occurring during the thermal destruction of such materials in synchronous thermal analysis with the study of degradation products are considered. The effectiveness of the use of plasma technologies in the treatment of bitumen - containing waste has been studied and it has been established that the ratio of the mass of waste material to solid residue ash reaches 400:1, thus the degree of processing is more than 99,7 %. The authors proposed an alternative technology that allows the use of bitumen contained in the waste of waterproofing materials as an organic raw material for further use in the construction industry. Considered is the chemical recovery of bitumen using various organic solvents, such as technical kerosene, carbon tetrachloride, chloroform and trichlorethylene. According to the calculated indices of correspondence of the chemical composition, it was established that carbon tetrachloride is the most effective solvent. The chemical composition of the bitumen extracted with this solvent is closest to the control sample taken without the participation of solvents.
THE INFLUENCE OF THE GEOLOGICAL STRUCTURE OF THE TERRITORY ON THE FLOODING OF BUILDING BASEMENTS
Authors: Gryaznova Elena М.
Published: March 2023

The article deals with the construction of buildings in relatively shallow pits (up to 5 m), passed in the connected soils of water - glacial deposits with layers of sand and gravel material. It is noted that the features of these soils include the possibility of forming a sporadically developed aquifer in them with a very low filtration coefficient (less than 0.01 m/day). Due to this circumstance, this horizon is not always fixed in engineering and geological surveys and, as a result, is not always taken into account in the design. Therefore, in order to save money during construction, they are usually limited to the device of waterproofing the walls of the basement, and bulk material is used as soils for backfilling the sinuses of the pit. Thus, in the buried sinuses of the pit, an environment capable of accumulating water is formed. With the gradual filling of this tank, in conditions of impossibility of diverting water into the soil mass of the base, due to the low filtration coefficient and when creating appropriate pressure gradients, as well as in the presence of possible defects in waterproofing, there are stable leaks in the basements of buildings already ready for use. The article deals with the occurrence of such situations on a number of examples of erected buildings. The main sources of water supply to the buried sinuses of the pit are indicated and a number of practical measures are given to avoid such situations in the future.
THE RESTRAINED EXPANSION STRAINS OF SELF-STRESSED CONCRETE WITH DISPERSE REINFORCEMENT PART 1. MODELING
Authors: Pavlova Inessa P. , Belkina Irina V.
Published: March 2023

The introduction discusses the use of self - stressing concrete in reinforced concrete structures. The object of study is fiber reinforced self - stressing concrete. The analysis of the existing experience of using it in structures with various reinforcing elements is carried out. Positive effects have been noted when fibers are added to self - stressing concrete. The relevance of the topic under study is substantiated. It is noted that the empirical approach to estimating restrained expansion strains is not universal, therefore, the main direction that allows one to proceed to predicting properties and minimizing possible experimental studies is analytical and mathematical modeling. The existing models based on the deformation approach are analyzed. The distinctive features of the models for each case of limitation are given. The preconditions and assumptions of the modified strains development model for the case of a triaxial (volumetric) constraint are formulated. A modified model is proposed for determining the restrained expansion stresses and strains of self - stressing fiber - reinforced concrete at the expansion stage. The proposed analytical model can be used in design, educational and research institutions.

Authors: Sebeshev Vladimir G. , Lyuft Nikita A. , Nikolskiy Anton V.
Published: March 2023

Structural mechanics methods were used for investigation the stability of flat trusses with rigid nodes, taking into account the simultaneous longitudinal - transverse bending of all rods as a result of the equilibrium forms bifurcation. The values of the reduced buckling length coefficients for compressed elements are obtained and systematized with varying of main parameters of the design models, namely their geometry, lattice types, loading schemes and rods stiffness’ ratios. The calculated values of the reduced length coefficients are compared with the recommended by the current standards for the design of steel structures. In a number of cases, significant discrepancies were revealed both in the direction of excessive stability margin and with a dangerous underestimation of the critical load parameter. The results indicate the expediency of changing the regulatory concept of truss’s stability calculations, with the transition from element - by - element verification to the analysis of the structure’s overall stability.

Серед ключових факторів, які негативно впливають на процес іноземного інвестування виокремлено воєнні дії на території України, високий рівень інфляції, нестабільність фінансової системи та податкової системи. Досліджено розподіл прямих іноземних інвестицій в Україну за видами економічної діяльності, а також в регіональному розрізі. Встановлено, що за галузевою привабливістю нині пріоритетними сферами для інвестування є промисловість, сільське і лісове господарство, а також оптова та роздрібна торгівля. Значна увага зосереджена на змінах в структурі та обсягах прямих іноземних інвестицій, зумовлених введенням воєнного стану в Україні. Окреслено перспективи інвестиційної діяльності.

Published: March 2023

Sustainable accounting is a concern where demands on financial information become wider. The research aims to analyze the effect of EMA on the company's financial performance and working capital management (WCM) as a mediator. The data was obtained through a questionnaire survey of seventy eight respondents from textile manufacturing companies in Bogor Regency. The path analysis model is tested using Smart PLS. The results of the study found that EMA has a direct significant effect on financial performance and the role of working capital management as a mediator contributes to the indirect effect of EMA on financial performance. EMA information is critical in providing information that increases managers'

Teaching Emerging Technologies as Legal Systems: Proposals for a Changing Law School Curriculum
Authors: Graben Sari
Published: March 2023

In this article, I draft the outlines of a law school program that delivers a systemic approach to legal education with a technological focus. I explore the application of systemic learning through three teaching pillars: technology as part of the legal system, user based learning and innovation based learning. By placing these goals at the core of the curriculum, I expand upon the theoretical significance of technology to the construction of law and provide a framework for reorienting some part of legal education towards understanding the technological systems used to ‘produce’ law while teaching practice within it. 
Creating Indigenous Property: Power, Rights, and Relationships
Authors: Cameron Angela , Graben Sari , Napoleon Val
Published: March 2023

While colonial imposition of the Canadian legal order has undermined Indigenous law, creating gaps and sometimes distortions, Indigenous peoples have taken up the challenge of rebuilding their laws, governance, and economies. Indigenous conceptions of land and property are central to this project.

Creating Indigenous Property identifies how contemporary Indigenous conceptions of property are rooted in and informed by their societally specific norms, meanings, and ethics. Through detailed analysis, the authors illustrate that unexamined and unresolved contradictions between the historic and the present have created powerful competing versions of Indigenous law, legal authorities, and practices that reverberate through Indigenous communities. They have identified the contradictions and conflicts within Indigenous communities about relationships to land and non-human life forms, about responsibilities to one another, about environmental decisions, and about wealth distribution. Creating Indigenous Property contributes to identifying the way that Indigenous discourses, processes, and institutions can empower the use of Indigenous law.

The book explores different questions generated by these dynamics, including: Where is the public/private divide in Indigenous and Canadian law, and why should it matter? How do land and property shape local economies? Whose voices are heard in debates over property and why are certain voices missing? How does gender matter to the conceptualization of property and the Indigenous legal imagination? What is the role and promise of Indigenous law in negotiating new relationships between Indigenous peoples and Canada? In grappling with these questions, readers will join the authors in exploring the conditions under which Canadian and Indigenous legal orders can productively co-exist.
Aboriginal Title in Tsilhqot’in: Exploring the Public Power of Private Property at the Supreme Court of Canada
Authors: Graben Sari , Morey Christian
Published: March 2023

[From Introduction]: "The decision of the Supreme Court of Canada in Tsilhqot’in Nation v British Columbia was a watershed in Canadian jurisprudence. It recognized the Aboriginal title of the Tshilhqot’in First Nation on the basis of territorial usage and it ensured that the financial benefits of land and resources will flow to the Tsilhqot’in (rather than the Crown or third parties). The Court recognized that title holders enjoy all of the “incidents” normally associated with fee simple ownership, and limited the Crown’s interest in Indigenous lands to a residual form of title (with no beneficial interests). As a result, the Court has forwarded a conception of title that highlights the financial benefits of Aboriginal rights for Aboriginal peoples." 
Arctic Networks and Legal Interpretations of the UN Commission on the Limits of the Continental Shelf
Authors: Graben Sari , Harrison Peter
Published: March 2023

The United Nations Commission on the Limits of the Continental Shelf is expected to play an essential role in delineating the rights of the Arctic states to seabed resources in the Arctic Ocean. In this article, the authors look to the effect of scientific discourse on Commission authority. The authors argue that in addition to the conferral of its authority by the United Nations Convention on the Law of the Sea, the Commission draws its authority in the Arctic from the way its regulatory frameworks, aimed at containing or closing off disputes about jurisdiction and sovereign rights, correlate with discursive practices used by transnational networks to reach scientific agreement.
The Nisga’a Final Agreement: Negotiating Federalism
Authors: Graben Sari
Published: March 2023

The Nisga’a Nation, federal government and provincial government of British Columbia completed negotiation of the Nisga’a Final Agreement on 4 August 1998. Although the parties incorporated the language of nationhood, new relationships, and intergovernmental agreement, to many it remains unclear whether the Nisga’a Final Agreement creates a third order of Canadian government. This article wades into the debate on the third order and asks whether the treaty text supports a federal relationship. While it is clear that the type of federal relationship described by the Nisga’a Final Agreement is different from that of the provincial and federal governments, the treaty’s use of federalism’s foundational legal and political institutions supports understanding it as federal. Moreover, its reading as a federal document can find sufficient support in the jurisprudence on Aboriginal rights and Canadian constitutional law.  
Assessing Stakeholder Participation in Sub-Arctic Co-Management: Administrative Rulemaking and Private Agreements
Authors: Graben Sari
Published: March 2023

This paper argues that participatory governance initiatives like co-management can be made effective through agency rulemaking. Using the Mackenzie Valley Environmental Impact Review Board as a case study, this paper affirms that it is possible for marginalized stakeholders to participate in co-management and alter decision-making. By using its formal authority to generate rules that reflect community perspectives, this board contextualized environmental assessment in community-based perspectives. The study of participation presented here illustrates: 1) that a high level of agency support for community participation in rule-making can lead to rules which reflect community perspectives; and 2) that agency implementation of community perspectives has led to the increased use of stakeholder collaboration through private agreement. Nonetheless, the paper also addresses limitations on the ability to translate social needs into privately negotiated agreements where negotiations depart from highly commoditized terms. Consequently, this paper questions the use of negotiated agreements to meet the goals of stakeholder participation, as conceived by deliberative democratic strands of new governance.

 Dans cet article, l’auteure soutient que le pouvoir de règlementation d’un organisme peut rendre plus efficace de nouvelles initiatives en matière de gouvernance telles que la cogestion. Prenant l’Office d’examen des répercussions environnementales de la vallée du Mackenzie comme exemple, elle affirme que des parties prenantes marginalisées ont la possibilité de participer à de nouvelles modalités de gouvernance comme la cogestion et d’influer sur la prise de décision. En exerçant son pouvoir d’adopter des règles inspirées des valeurs communautaires, l’Office a procédé à une évaluation environnementale en tenant compte du contexte communautaire. L’étude de participation présentée ici démontre: 1) que, lorsqu’un organisme appuie fortement la participation de la collectivité à l’élaboration des règles, les règles adoptées peuvent davantage refléter les valeurs   communautaires; et 2) que l’adhésion de l’organisme aux valeurs communautaires favorise une plus grande collaboration entre les parties prenantes, grâce à la conclusion d’ententes privées. Quoi qu’il en soit, l’article révèle également que la capacité d’exprimer des besoins sociaux dans des ententes privées négociées est limitée. Lorsque les négociations dévient des termes hautement standardisés et tentent d’inclure différentes valeurs communautaires, la participation des parties prenantes est restreinte. L’article remet par conséquent en question l’utilisation d’ententes négociées pour atteindre les buts fixés en matière de participation des parties prenantes, telle que les conçoivent les courants de pensée s’appuyant sur la démocratie délibérative au regard de la nouvelle gouvernance
