Authors: Simón Ramos Maria Guadalupe , Miguel Aguilar Moisés Ricardo
Published: September 2021

La escasa presencia de las mujeres en Olimpiadas de Matemáticas parece ser una constante en México, Latinoamérica e incluso en occidente. Esta situación se ha obviado, y hasta cierto modo naturalizado, por las instituciones y personas implicadas. Analizamos como esto se vive en el estado de Tamaulipas en México, enmarcada por las políticas públicas y la influencia de la Olimpiada propuesta por la Sociedad Matemática Mexicana. Describiremos las acciones que hemos llevado a cabo para fomentar la participación de más niñas, pero también para apoyar el desarrollo del potencial, motivación e intereses de quienes ya participan en ellas. Por medio de un análisis descriptivo de su trayectoria en el concurso encontramos que pesar de tener un alto desempeño, es muy poco probable que elijan una carrera relacionada con Matemáticas. Factores como el profesorado y la familia tienen una influencia importante, pero también la dinámica de este tipo de eventos.
Intertekstualnost i intermedijalnost internetskih medijskih sadržaja o virusu COVID-19
Authors: Tkalec Gordana , Kocijan Samanta
Published: September 2021

Mediji su 2020. godinu počeli različitim nagađanjima o proročanstvima o virusu COVID-19, najavljenima kroz film i roman pa čak i Bibliju. Nisu se libili poistovjetiti posljedice kuge s onima od virusa COVID-19 čime su potaknuli različite rasističke i ksenofobne ispade u komentarima čitatelja. U ovom radu je kroz aspekt intertekstualnosti i intermedijalnosti opisana situacija u svjetskom medijskom prostoru tijekom pandemije COVID-19. Intenzivno korištenje intertekstualnosti i intermedijalnosti uzrokovano je zadovoljavanjem potreba publike da kroz povezivanje poznatih i novih sadržaja smanji strah od nepoznatoga i familijarizira se s novim pojmovima i novim situacijama. Prevelika količina nepoznanica koja je postojala osobito početkom pandemije morala se nadomjestiti ranijim iskustvima kako bi publika lakše usvojila željene obrasce ponašanja. Nakon što su obrasci ponašanja usvojeni, počinju se koristiti i u komercijalne svrhe.

Authors: Vallejo Ruano Gustavo , Morcillo Losa José Alfonso
Published: September 2021

El objetivo del presente estudio fue analizar la posible relación entre un trabajo de fuerza y el aumento del rendimiento en futbolistas (medido a través del cambio de dirección, CDD) y en la prevención de lesiones. Para ello, se contó con una muestra de 16 futbolistas de alto nivel pertenecientes al Granada CF con experiencia en trabajo de fuerza. Se realizó un test para medir el CDD en diferentes angulaciones (90º, 120º y 180º) medido con células fotoeléctricas. También se registró la potencia en diferentes acciones (salida frontal, lateral y de espaldas en VersaPulley), y la fuerza en una prensa de piernas (medida a diferentes cargas). Además se realizó un seguimiento de las lesiones manifiestas los 3 años precedentes al proceso de intervención como durante el mismo, con una duración de 3 meses. Tras el periodo de intervención que consistió en un programa de fuerza con predominio excéntrico, se observó un aumento en los niveles de potencia/fuerza adquiridos. Además, se encontró una correlación positiva entre el trabajo de fuerza con predominio excéntrico y la mejora en acciones como el cambio de dirección. Por otro lado, el porcentaje lesivo global del equipo fue menor que antes del programa de intervención. Por tanto, la relación entre la fuerza con predominio excéntrico y el rendimiento en las acciones del fútbol fue positiva, de igual modo que con el porcentaje lesivo de los sujetos evaluados.

Published: September 2021

O objetivo desta pesquisa é correlacionar a memória, a atenção e os riscos cardiovasculares de adolescentes atletas e atletas profissionais praticantes de basquetebol e comparar as variáveis analisadas entre categorias. Este foi um estudo transversal, com caráter quantitativo e descritivo. A população deste estudo foram os praticantes de basquetebol do Anápolis Basquete e da Associação Desportiva Vultures Anápolis, com total de 22 praticantes da modalidade, sendo 10 adolescentes da categoria sub-19 e 12 atletas profissionais. Foram analisados os riscos cardiovasculares a partir do peso, altura, circunferência da cintura, pressão arterial e cortisol. Para avaliar a memória e a atenção, foram utilizados três instrumentos: o Memo, que avaliou a memória recente, a atenção e a concentração; o Velotest, avaliou a atenção, a agilidade e a coordenação motora fina; o Stroop eletrônico que avaliou a atenção seletiva. Os resultados, comparando-se os dois grupos, apresentaram diferença significativa na idade e na atenção. Os adolescentes da sub-19 obtiveram maior média na atenção (18,92±1,08); porém, ao se comparar a idade com a atenção, obteve-se uma correlação negativa (r=-0,461). Concluiu-se que, ao correlacionar memória e atenção e comparar suas variáveis, os adolescentes atletas mais novos tiveram médias maiores em relação aos atletas profissionais. Quanto aos riscos cardiovasculares, os atletas profissionais tiveram níveis de cortisol menor que os adolescentes, ou seja, à medida que os adolescentes atletas ficam mais velhos ou mudam de categoria, eles aumentam o peso, a altura e o circunferência da cintura com uma diminuição na memória, atenção e no cortisol.

The reflections of this article goal at the professionalization of the teaching career, which is one of the objectives aimed at the quality of education. The current socio-economic dynamics and complexity require continuous adaptability from teachers. They are put in the situation to periodically develop their professional skills, in order to meet both the the updated students’ educational needs, as well as the scientific innovations that result from the research in various fields. An interesting aspect is related to the needs and challenges of teachers in conditions of pandemic coronavirus (SARS CoV-2). The new conditions have imposed the transition of pedagogical practice in the online environment, an alternative adopted in many teacher training programs. As this decision was considered better than a temporary withdrawal from practice, students and their mentors had to adapt. For the future we have another certainty, that the pandemic will not stop very soon. Otherwise, the future is a matter of probability. The topicality of the topic researched in this article lists the professional training, taking into account the endowment of teachers with the necessary skills so that they feel comfortable in all situations that may arise during their teaching activities. Dynamism, flexibility, receptivity to the new and critical reflection on curricular requirements and methodological approach define the modern teaching profession.
Using Kinetic Energy with Potential Energy When Determining Power During the Stair Climbing Test
Authors: Roush James , Heick John , Genovese Joseph , Kurashima Kyle , Yarrington Dallin
Published: September 2021

ABSTRACT Stair climbing is an important functional task that indicates independence, and generating power to climb stairs is a vital component of this task. Power during stair climbing is traditionally calculated using potential energy (PE), but it may be important to determine power expended using kinetic energy (KE). Purpose: The current study assessed power output for stair climbing with and without the inclusion of KE. Methods: Sixty participants (21-35 years) climbed a 12-step stairway with a 2-meter acceleration phase before the first step and a 2-meter deceleration phase after the last step. Participants completed 3 trials, and average time was used for calculating energy expended and power. Results: The mean difference between power from PE and total power was 6.16 W (SD = 2.50, t29 = 13.49, p < 0.001) for males and 64.76 W (SD = 2.90, t29 = 8.99, p < 0.001) for females. Agreement between power calculated from PE and total power was 0.99 (95% confidence interval = 0.98-1.0). Conclusion: Power calculated using PE and KE was significantly different from using PE alone, which may be clinically important. When conducting stair-climbing tests, both PE and KE may be necessary for the most accurate assessment of power.
Can the Forward-Step-Down Test Be Used Reliably in the Clinical Setting to Assess Movement Changes Resulting from Maximal Exertion? A Pilot Study
Authors: McCallister Erin , Flowers Daniel
Published: September 2021

Introduction: Visual assessment of lower extremity mechanics is used frequently in clinical practice, and objective scoring of the visual assessment is beneficial to improve objectivity of patient evaluation. In addition, lower extremity mechanics change with fatigue and these changes may increase the risk of lower extremity injury. The Forward-Step-Down Test (FSDT) is one such objective tool, but its ability to detect changes in movement quality in response to exertion are not known. Methods: This study utilized a repeated-measures design, where the participants were scored on the FSDT before performing the Bruce protocol for an exertion stimulus. The participants were re-scored on the FSDT at one, five, and ten minutes after completing the Bruce protocol. Results: Wilcoxon signed-rank tests showed a significant change in FSDT score between baseline and five minutes post-exertion (a< .017). Friedman’s ANOVA was non-significant across all four assessments. In addition, despite testing healthy young adults, 50% of participants scored as “poor” movement quality on the initial test. This number increased to 75% at significant five-minute post-exertion mark. Discussion: Median scores on the FSDT were significantly different at five minutes post-exertion. However, this statistically significant change is of questionable clinical relevance because the median score changed by 0.5. This small change from 3.5 to 4.0 may not represent a change in overall movement quality from “moderate” to “poor.” Results do indicate that the participants in this study overall had poorer than expected movement quality throughout the testing. These results suggest larger data collection and analysis may be warranted for this population and the general population prior to partaking in exercise. Conclusion: The FSDT detects changes in lower extremity mechanics five minutes following a single exertion stimulus. Participants’ scores returned to baseline by ten minutes post-exertion. The FSDT may be a viable tool to assess changes in lower extremity movement quality following a single bout of exertion, and may help determine when participants have recovered back to baseline movement quality.
The Effect of Case Presentation on Student Physical Therapists' Clinical Reasoning Hypotheses
Authors: LaRosa Nicholas , Dinsmore Daniel
Published: September 2021

Purpose: Clinical reasoning is an essential skill for Physical Therapists to develop for making sound decisions regarding patient care. Case-method teaching is an instructional strategy commonly implemented in physical therapy professional education programs for facilitating clinical reasoning skill acquisition. One advantage of case-method teaching is the various ways cases can be portrayed. The purpose of this study was to identify how a case is portrayed effects student thinking and their subsequent clinical decision making. Method: Third-year student physical therapists (n = 14) working in dyads clinically reasoned through a hypothetical musculoskeletal case presented via written case study or simulated patient experience. Talk aloud methodology via concurrent reports was implemented for data collection. Mann-Whitney U-tests followed by manual calculations of effect sizes were conducted for comparing hypothesis category generation between groups. Results: A total of 14 hypothesis categories were generated by the student dyads during the problem-solving sessions. Specifically, students generated more ideas regarding health condition, and contextual factors when thinking through a written case study whereas significantly more thoughts regarding symptom characteristics, client perspectives, and minimizing reasoning errors were generated during simulated patient experiences. Conclusion: When implementing case-method teaching, physical therapy academic educators need to be aware that the manner a case is portrayed affects the clinical judgements students generate and their learning of clinical reasoning. Future research should continue to investigate these effects and how they ultimately impact clinical practice.

En el ámbito hispanohablante, en muchos casos, existe una variación entre la terminología empleada en América y la terminología empleada en España. Lo mismo ocurre entre los diversos países que conforman América, entre los que se encuentra, por ejemplo, Perú, que cuenta con sus términos propios o peruanismos, que varían respecto de los términos empleados en España, y también del resto de países americanos. El objetivo del presente estudio, por consiguiente, es el de, por un lado, comparar un grupo de voces o expresiones utilizadas por los hablantes de Perú con sus equivalentes empleados por los hablantes de España y, por otro, confirmar el uso actual de estos peruanismos, para lo cual se han realizado consultas en el Corpus del Español del Siglo XXI (CORPES XXI). Los resultados obtenidos confirman que existe una variación léxico-morfológica entre el español de Perú y el de España, así como la pervivencia de la mayor parte de peruanismos recogidos en la presente investigación.

MODIFIED PSO ALGORITHM WITH NON-LINEARLY DECREASING INERTIA WEIGHT
Authors: Grewal Rayaan
Published: September 2021

This paper proposes a modified particle swarm optimization method with non linearly decreasing inertia weight (MPSO-NDIW) and time varying acceleration coefficients. In this MPSO-NDIW method, proper control of the global exploration and local exploitation is done in finding the optimum solution efficiently. In the early stage, full range of search space is allowed for search by the PSO algorithm and in the later stages of search, fine tuning of solution is done so that the algorithm converges to the global optima efficiently .In velocity vector equation inertia weight and acceleration coefficients are non-linearly varied with iterations. To compare the performance of the MPSO-NDIW method with the other improved PSO, four well known benchmark test functions are used. The results reveal that MPSO-NDIW is a efficient technique and has better performance.

Multilevel analysis of risk factors associated with severe
underweight among children under 5 years: evidence
from the 2014 Ghana Demographic and Health Survey
Authors: Aheto Justice M K , Deda Ogum-Alangea
Published: September 2021

Background: Undernutrition among children <5yr. is a global public health problem, especially in developing countries like Ghana. Undernutrition increases the risk of child morbidity and mortality. There is paucity of data on household-level effects on severe underweight and associated factors.

Objective: The study investigated the risk factors associated with severe underweight among children < 5yr.in Ghana and examined unobserved differences across households based on the 2014 Ghana Demographic and Health surveys (GDHS) data.

Methods: Data from a population-based cross-sectional study was obtained from the 2014 Ghana Demographic and Health Survey. Data on 2720 children nested within 1972 households was extracted for analysis. Our regression analysis used data on 2716 children with complete data on the outcome and risk factors. Children with weight-for-age Z-score below -3 standard deviations were classified as severely underweight based on the 2006 WHO child growth standards. We applied random intercept multilevel logistic regression to examine whether severe underweight status in children differ across households while simultaneously identifying potential risk factors.

Results: A total of 2720 children had valid weight-for-age z-score and 53 (1.95%) of them were identified as severely underweight. In the univariate model, child level variables such as multiple birth [odds ratio (OR), 4.03;95%confidence interval (CI): 1.85-8.76]and child born average (OR, 2.17;95%CI: 1.09-4.32) or small (OR, 4.08; 95%CI: 2.01-8.28) in size at birth are associated with increased odds of severe underweight. Maternal/household level variables such as increase in number of children below 5 yr. (OR, 1.61; 95%CI: 1.28-2.04), poorest households (OR, 4.85; 95%CI: 1.14-20.59) and increase in number of births in last 5 yr. (OR, 1.80, 95%CI: 1.24-2.60) were associated with increased odds of severe underweight. Increase in maternal years of education (OR, 0.89; 95%CI: 0.83-0.95) was associated with reduced odds of severe underweight. In the multilevel logistic model, only type of birth (OR, 1.61;95%CI: 1.28-2.04), size of child (average: OR, 2.12;95%CI: 1.04-4.33; small: OR, 3.87;95%CI: 1.80-8.33) at birth, and maternal education (OR, 0.92;95%CI: 0.84-1.00) were independently associated with severe underweight. There were no significant residual household-level variations in severe underweight status.

Conclusion:
Our findings suggest that improving maternal education, socioeconomic conditions of families, and family planning are critical in addressing severe underweight

Authors: Nyarko Samuel , Kusi Anthony , Opoku - Mensah Kwabena
Published: September 2021

Background: In the year 2000, member states of the United Nations pledged to work towards a three-quarters reduction in the 1990 maternal mortality ratio by 2015 in line with Millenium. Development Goal 5, but this could not be achieved. This pledge became imperative given the high maternal mortality being recorded, especially among developing countries. The high maternal deaths in developing countries have been attributed partly to the lack of access to skilled birth attendants during delivery.

Objective: This study aimed to investigate factors that influence the utilization of health facility delivery services among pregnant women in the Jomoro District of the Western Region of Ghana.

Methods: The study used data from a cross-sectional survey among women aged 18 - 49 yr. living in the Jomoro District of Ghana and had given birth between 2012 and 2016 (n = 374). The study participants were randomly selected from women who attended child welfare clinics on clinic days with their babies in eighteen communities. The study used a structured questionnaire to solicit for information about the women’s demographic and socio-economic characteristics, community characteristics and health systems factors likely to influence their decision to seek skilled delivery care as well as their experiences relating to their last delivery. Bivariate analyses were performed between the primary dependent variable and background characteristics of the respondents. Factors influencing the choice of place of delivery were estimated by multiple logistic regression analysis. Data analysis was performed using STATA Statistical Software, Release 14.

Results: About 61.0% (n= 228/374) of the women had their last delivery at a health facility while the remaining 38.8% (n= 145/374) delivered at home without skilled assistance. In multivariate analysis, women aged 25 – 29 yr. were less likely to have a skilled delivery (aOR, 0.40; 95% CI: 0.17 - 0.93). Also, professional women had 4.77 odds of having skilled delivery (aOR, 4.77; 95% CI: 1.53 - 14.93). Distance to the nearest health facility also had a statistically significant association with skilled delivery. Women living at 10 – 19 km to a health facility were less likely to have a skilled delivery (aOR, 0.56; 95% CI: 0.32 - 0.97). In addition, the presence of a midwife at a health facility increased the odds of skilled delivery among women (aOR, 4.59; 95% CI: 2.47 - 8.55).

Conclusion: Interventions aimed at increasing the uptake of delivery care services to achieve the SDG’s target on maternal mortality must consider improving the socio-economic wellbeing of women in addition to removing the physical and health system barriers impeding access and utilisation of delivery care services.

Authors: Kyei Mathew Y , Gjagbletey Robert , Klufio George O , Mensah James E , Toboh Bernard
Published: September 2021

Uretero-vesical anastomosis is the connection of the ureter to the urinary bladder at a new site to achieve unimpeded flow of urine from the ureters into the urinary bladder. A rare complication of this procedure is the development of stricture at the anastomotic site. This report is on a 62-yr. old female with one year history of left flank pain and a prior left uretero-vesical anastomosis done 14 years earlier. She had been managed for recurrent urinary tract infections, but the left flank pain was persistent. Abdominal and pelvic CT scan with intravenous urogram helped establish the diagnosis of uretero-vesical anastomotic stricture. This was successfully managed with endoscopic dilatation after retrograde placement of guide wire under fluoroscopy followed by serial dilation. In a patient presenting with flank pains after a previous uretero-vesical anastomosis, stricture at the anastomotic site is an important differential diagnosis. Endoscopic management is the preferred initial management which produces successful outcomes
AVERAGED CONTROLLABILITY OF THERMOELASTICITY EQUATIONS. AVERAGE STATE OF A RECTANGULAR PLATE
Authors: Jilavyan Samvel H. , Khurshudyan Asatur Zh.
Published: September 2021

The concept of averaged controllability has been introduced relatively recently aiming to analyse the controllability of systems or processes containing some important parameters that may affect the controllability in usual sense. The averaged controllability of various specific and abstract equations has been studied so far. Relatively little attention has been paid to averaged controllability of coupled systems. The averaged state of a thermoelastic rectangular plate is studied in this paper using the well-known Green's function approach. The aim of the paper is to provide a theoretical background for further exact and approximate controllability analysis of fully coupled thermoelasticity equations which will appear elsewhere.

Authors: Hall Janelle
Published: September 2021

Performance management frameworks in public educational institutions have not dealt with some of the challenges in creating an environment that reflects organizational commitment, sustainability, productivity, and retention among academic staff. The purpose of this article was to explore the experiences of people of color regarding the challenges they face involving the use of spiritual intelligence in the workplace. Gardner’s multiple intelligence theory served as the foundation for this article. The key research question focused on the perceptions of people of color working in nonprofit educational institutions regarding the role that spiritual intelligence played in their workplaces and career successes. Targeted research included face-to-face interviews with 10 participants older than 18 years old. Two findings revealed spiritual intelligence was viewed as an indirect tool used for career success and there are opportunities for human resources to promote spiritual intelligence to create a sustainable work environment to increase performance. I concluded that the results are useful for human resource management to implement programs for their employees to understand and apply their spiritual intelligence in the workplace environment.

The novel coronavirus causes varied symptomatology and several complications, among them, stand out those of the gastrointestinal tract. In order to discuss gastrointestinal complications in SARS-COV-2 infected patients and their outcomes, we’ve developed an integrative literature review, using Pubmed and BVS databases. The following descriptors were used: covid-19, Sars-cov-2, gastrointestinal Tract, and Complications. The selected studies presented patients with covid-19 and gastrointestinal complications. The majority of the 13 articles included were case reports, in Europe, mostly men at the age of 60 or more. As for complications, ischemia, gastrointestinal bleeding, and pneumatosis, arterial narrowing and thrombosis stands out. In diagnoses, commonly exam was the reverse polymerase-transcriptase chain reaction; treatment varied between conservative and surgical resection. It’s evident the importance of good practice, early diagnosis and treatments, avoiding at its most the worsening of the condition. However, whereas is such a recent subject matter, further studies need to be made.

Published: September 2021

China, Japan and Ayutthaya (Thailand) are three countries located in Asia - a cultural, civilized and economic center of the world in history and at present. In the 16th - 17th centuries, building diplomatic relations and implementing foreign policies with Southeast Asian countries were always the concern of major countries in the region, especially China and Japan. In the foreign policy of China and Japan, Ayutthaya was one of the countries that had an important position and brought many economic and political benefits. On the contrary, establishing a good relationship with a powerful country like China and a country with a developed maritime trade like Japan would benefit Ayutthaya in many ways in international relations, expanding its sphere of influence as well as economic and political development in the 16th and 17th centuries. The article delves into the policies of China and Japan towards Ayutthaya (16th - 17th centuries) in order to clarify the similarities and differences in the regional policies of two major countries as well as the role and position of Ayutthaya in Southeast Asia during the pre-modern centuries.

Published: September 2021

Objective: The purpose of study was to identify the knowledge, attitude and practice of prevention NSIs among nursing students in Henan province, China.
Methods: A cross-sectional study of 400 nursing students in 7 nursing education institutes in Henan province during June to July 2019 was performed. Structured questionnaires were used to assess participants' knowledge, attitudes and practices of prevention NSIs. Chi-square tests were used to assess correlations between variables. Multivariate regression analysis was used to test the factors related to prevention NSIs.
Results: It has shown that 67% of nursing students suffered at least one NSI during their internship. The most common cause of injury was the injection process, the venous catheter management process, and the disposing all kinds of needle waste process (p<0.05). Female students showed more than three times greater chance of intentionally breaking needle after injection (OR 2.50, 95%CI 1.03-6.08). Capping needles always used by two hand (OR 0.40, 95%CI 0.19-0.85) and separating the needle from the syringe by hand after injection (OR 0.23, 95%CI 0.16-0.57) were negatively related to bachelor students.
Conclusion: Nursing students show high prevalence of NSIs and lack of prevention knowledge, attitude, and practice. It’s necessary to develop and increase occupational safety protection courses and establish regulations for the prevention of NSIs.

Treatment-related mortality in children with acute lymphoblastic leukemia in a low-middle income country
Authors: Rahat-Ul-Ain  , Mahwish Faizan  , Wasila Shamim
Published: September 2021

Objective: To determine the proportion of treatment-related mortality (TRM) among mortalities of Pediatric Acute Lymphoblastic Leukemia (ALL), to identify probable causes and risk factors.
Methods: An observational; retrospective, cohort study. Pediatric patients of ALL who expired during treatment were enrolled. Death due to relapse and deaths before treatment were excluded. Retrospective data was collected from ward record and analyzed in SPSS 16.
Results: Total 247 patients of ALL expired while 144 patients were enrolled as per inclusion criteria. The proportion of TRM was 58.3%. Median age was 5 years. Male-to-female ratio was 1.3:1. Commonest cause of TRM was sepsis (n=126, 87.5%), followed by hemorrhagic complications (n=11, 7.6%), drug toxicity (n=4, 2.8%), tumor lysis syndrome (n=2, 1.4%) and thromboembolism (n=1, 0.7%). Significant factors associated with TRM were weight-for-age, immunophenotype, reason for admission and absolute neutrophil count.
Conclusion: Treatment-related mortality though potentially avoidable is still a major cause of death among pediatric patients of ALL in low-middle income countries. Sepsis is the most common cause and infection prevention and control is vital in improving survival. Best supportive care must be made available for the patients on induction chemotherapy, with concomitant malnutrition, high-risk immunophenotype and profound neutropenia.

Szemelvény a Bécsi Vételi Egyezmény alkalmazása köréből – tekintettel a magyar bíróságok legújabb esetjogára
Authors: Vadász Vanda
Published: September 2021

Jelen tanulmány az 1987. évi 20. törvényerejű rendelettel kihirdetett, az Egyesült Nemzeteknek az áruk nemzetközi adásvételi szerződéseiről szóló, Bécsben, az 1980. évi április hó 11. napján kelt Egyezmény legújabb bírósági gyakorlatát vizsgálja. A tanulmány kiterjed az Egyezmény személyi, tárgyi és területi hatályának elemzésére, a joghatóság megállapítása és az alkalmazás összefüggéseire, valamint a magyar rendes bíróságok előbbiekkel kapcsolatos legújabb gyakorlatára, figyelembe véve a hozzáférhető esetjogot.
Az Európai Bankunió reformja – a makroprudenciális felhatalmazások rendszerének újragondolása a kelet- és közép-európai országok szemszögéből
Authors: Mérő Katalin , Piroska Dóra
Published: September 2021

A szerzők cikkükben amellett érvelnek, hogy fontos az Európai Bankuniót (BU – a továbbiakban általában: Bankunió) vonzóbbá tenni a kelet-közép-európai országok számára. Ugyanis csak így lesz képes a Bankunió egyszerre növelni az egységes piac hatékonyságát és biztosítani egész Európa számára a pénzügyi stabilitást. Első lépésben a szerzők megmutatják, hogy miért nem vonzó jelenleg a Bankunió a kelet- és közép-európai országok számára. Áttekintve az európai bankszabályozás történetét, rámutatnak arra, hogy a szabályozás logikáját a válság előtt a szubszidiaritás elve és az európai szintű egységes szabályozás elve közötti kényes egyensúly jellemezte. Azt állítják, hogy a Bankunió nem ezt az elvet követi. A Bankunió központi elemévé váló makroprudenciális bankszabályozás példáján mutatják be, hogy az Egységes Felügyeleti Mechanizmus létrehozását és ezen belül a makroprudenciális mandátumok allokációját egy új logika: az euró megmentése és a szuverén és banki kockázatok között kialakult ördögi kör megtörésének igénye vezette. Ez a logika idegen a külföldi banktulajdon dominálta eurózónán kívül maradó kelet-európai országok számára. Vagyis, bár elismerik és hangsúlyozzák, hogy a válság óta a kelet- és közép-európai országok bankpolitikáját egy erőteljes banknacionalista vonulat jellemzi, itt amellett érvelnek, hogy a Bankunión való kívül maradásukat a Bankunió által megvalósított új szabályozási logika is indokolja. Kritikájukban ugyanis a korábbi bankszabályozási elv – a szubszidiaritás – hiányára mutatnak rá: kifogásolják a makroprudenciális kompetenciák és a makroprudenciális döntésekért viselt felelősség összhangjának hiányát. Ezért a szerzők olyan reformjavaslatokat fogalmaznak meg, amelyek képesek megszüntetni ezt az aszimmetriát. Teszik ezt azért, mert véleményük szerint a Bankunió ilyen irányú reformja hatékonyabbá és így előnyösebbé tenné azt minden uniós tagállam számára.
A CISG három dimenziója
Authors: Emery Cyril , Castellani Luca G.
Published: September 2021

Harmincöt év elteltével a Nemzetközi Adásvételi Szerződésekről szóló Egyezmény (CISG) megalkotása után, az UNCITRAL felmérte annak alkalmazási tendenciáit. A gyakorlati tapasztalatok az Egyezmény három dimenziójára világítottak rá. Az első dimenzió a CISG jelenlegi helyzetét vizsgálja. Rámutatnak arra, hogy a nemzetközileg jelentős, nagyobb gazdaságnak számító államok széles körben fogadták már el a konvenciót, viszont néhány nagyobb gazdaság még hiányzik. A második dimenzió arra világít rá, hogy a CISG a regionális és a hazai adásvételi jogi tárgyú jogfejlesztésekre is ösztönző módon hat, továbbá az általános szerződési jog területén is modellként szolgál. A harmadik dimenzió pedig kiemeli, hogy a Vételi Egyezmény alkalmas a globális joganyaggá válásra. Ahhoz viszont, hogy nemzetek feletti joggá váljon, többet kell tenni a további országok által történő hivatalos elfogadás, a szélesebb körű alkalmazás és az egységes értelmezések elősegítése érdekében. Ennek egyik módja lehet egy, az adásvételi jogra összpontosító iránymutató dokumentum elkészítése, ami felölelné magát a Vételi Egyezményt és minden más, a nemzetközi adásvételre vonatkozó egységes szabályt is, valamint olyan témákat érintene, amelyek jogalkotók, bírák, választott bírák, ügyvédek és kereskedelmi cégek érdeklődésére egyaránt számot tartanak.
Hol volt, hol nem volt... Kínai tőkebefektetések Magyarországon és Kelet-Közép-Európában
Authors: Sass Magdolna
Published: September 2021

A cikk a szakirodalom eredményei alapján bemutatja, hogy a kínai külföldi közvetlentőke-befektetések és multinacionális vállalatok sajátosan viselkednek más országok külföldön befektető vállalataihoz képest. Ennek okát a kínai gazdasági modell sajátosságaival magyarázhatjuk, amelyben az állami-kormányzati beavatkozás a gazdaság minden szeletét áthatja. Jelezzük továbbá, hogy a kínai közvetlentőke-befektetések volumene és súlya nagyobb Európában és Kelet-Közép-Európában, mint azt az eddig elérhető adatok mutatták. A régió s azon belül is elsősorban Magyarország relatíve fontos célpont az Európai Unión belül a kínai tőke számára. Lakosságszámához vagy gazdasági erejéhez (GDP-jéhez) viszonyítva hazánk a kínai tőke fontos európai fogadó országai közé tartozik. A magyarországi kínai projektek jellemzői hasonlítanak a kínai külföldi közvetlentőke-befektetéseknek a szakirodalomban bemutatott általános sajátosságaihoz. Ezért – más fogadó országok tapasztalatai alapján – a fejlett országokból származó befektetésekhez hasonlítva kockázatosabbnak tekinthetők.
A termelési tényezők szerepe az európai járműipari értékláncban
Authors: Vakhal Péter
Published: September 2021

A nemzetközi értékláncokba beszállított hozzáadott érték nagysága az értékláncban elfoglalt pozíció függvénye. A cikkben a szerző azt vizsgálja, hogy milyen különbségek léteznek a különböző termelési fázisokra szakosodott iparágak között az európai járműiparban. Feltételezésünk szerint az alacsonyabb hozzáadott értéket beszállító iparágakban a munkaerő mint termelési tényező szerepe nagyobb, mint a tőkéé. Minél magasabb azonban az előállított hozzáadott érték, annál nagyobb szerep jut tárgyi eszközöknek és az immateriális javaknak. Az elemzés során a szerző úgy találta, hogy a tőke skálahozadéka egyértelműen pozitív kapcsolatba hozható az értékláncban elfoglalt pozícióval, míg a munka skálahozadéka jellemzően alacsonyabb, ha a beszállított hozzáadott érték magasabb.
The Adjudication Function of the Election Supervisory Body (ESB) in Realizing Election Justice
Authors: Raden Sahran
Published: September 2021

ESB's adjudication role and the nature of its presence in Indonesia's electoral justice system are the focus of this research. In a normative juridical approach and analytic descriptive, the researcher examines the legal norms in relevant laws and regulations to determine whether they have been violated. Indonesia's Election Supervisory Board (ESB) was created to ensure free and fair elections that adhere to democratic principles. The election adjudication function is attributable to Law Number 7 of 2017 concerning the ESB as an institution with the authority to resolve electoral process disputes. The existence of the ESB institution has made many positive contributions to the process of democracy development in Indonesia, the large number of violations originating from findings and reports handled by the ESB, is able to provide a deterrent effect for perpetrators of violations of laws and regulations, both election participants and election organizers.
