Authors: Zinchuk Tetyana , Kutsmus Nataliia , Prokopchuk Oksana , Kovalchuk Oleksandr , Usiuk Tetiana
Published: July 2021

The article is devoted to identifying the peculiarities of Ukraine's participation in international business and determining the prospects of strengthening the country's position under conditions of the new stage of global development. It is established that Ukraine's international trade activity's dynamics and trends coincide with world trade trends. However, its share in global exports remains negligible (less than 0.25%). On the world market, the country is traditionally positioned as resource-oriented, steadily increasing the volume of resources exports, including agricultural products. Instead, the dynamics of the Ukrainian economy transnationalization is low and does not coincide with the high rate of this process development at the world and developed countries level. Transnational companies also perceive Ukraine as a country with a strong resource base and a large internal market. The scientific novelty of the study is the identification of the level of Ukraine's integration into the system of international economic relations and argumentation of the reasons and results of disproportional participation of the country in international business at all stages of its development.
Antecedents of Trust in E-Government: Palestinian Citizens' Perspective
Authors: Alkhateeb Maan Ali , Abdalla Rania Ahmad
Published: July 2021

Many countries in the Middle East region are adopting the e-government portals to provide services to the citizens. Citizens should be satisfied with these portals and judge them as trustworthy in order to participate in the e-government activities as a primary stakeholder. This study aims to investigate the antecedents of trust in e-government in Palestine from citizens' perspective. The proposed model consisted of four main constructs including technical, governmental, risk factors, and propensity to trust in technology, in addition to five demographic characteristics (age, gender, educational level, income, and internet experience). A closed question questionnaire was designed to collect data, 340 valid questionnaires were retrieved. Simple and Multiple regression analysis were used to build an adequate model. Findings revealed that each construct has separately influenced trust level in e-government, but when combined together, technical and governmental factors have positive influence on citizens' trust level in e-government services, risk factors have a negative influence, whereas the influence of propensity to trust was eliminated. Surprisingly, demographic characteristics showed no statistically significant differences in the level of citizens' trust in e-government. These findings may help government official in improving e-government services by enhancing security measures adopted on the e-government portals thus encouraging citizens to use these services
Social Media Adoption and its Impact on SMEs Performance A Case Study of Palestine
Authors: Alkhateeb Maan Ali , Abdalla Rania Ahmad
Published: July 2021

Many small-medium size enterprises (SMEs) are adopting social media platforms to contact their potential customers and provide their services. The impact of this adoption on the SME's performance has been roughly examined by researchers in the Middle East region particularly Palestine. Constructs and variables of three models (TOE, TAM, TPB) were used as potential predictors of social media adoption including technological, organizational, environmental context, perceived ease of use, perceived usefulness, attitude toward technology, and capability to control technology. Furthermore, the influence of this adoption on SMEs performance was also tested. A closed question questionnaire was used to gather the data, and simple regression analysis was used to examine the hypotheses.  Findings revealed that all of the seven independent construct/variables except the technological context positively influence SME's adoption of social media, and social media adoption in turn positively influence SME's performance. The findings may be beneficial to SMEs's managers and the authorities as well to facilitate the use of social media by SMEs.

Published: July 2021

The article is devoted to determining the priority directions of local self-government bodies’ activity in the development of regions. Local self-government bodies are public entities that are empowered to deal with issues that are relevant to the well-being of the respective territorial community. Protecting the interests of the local community is a key objective of local self-government. The reform of local self-government in Ukraine is currently underway, the main purpose of which is decentralization of state power with the provision of territorial communities with resources and the mobilization of their internal reserves to provide the population with an adequate level of services. Such a goal could be achieved through effective local government action on regional development. The article analyzes the normative and legal support of the capacities of local self-government bodies to determine the priority opportunities for the development of regions and to provide support for such development. It is established that the local self-government bodies in determining the priority directions of development of the regions should take into account various factors such as: geographical, demographic, personnel, environmental, economic, historical and cultural. Attention is drawn to the need for a comprehensive approach to the analysis of such factors by local governments. The article analyzes a number of factors that have a negative impact on the current state of regional development. The directions of activity of local self-government bodies to avoid or minimize the consequences of such influence on the development of regions are suggested. It has been established that local governments can use tax, information, innovation and other measures of influence in order to stimulate priority directions of regional development. The emphasis is placed on the role of local authorities in the development of tourist attractiveness of regions, in particular in the field of international and interregional cooperation as a means of forming a positive image of the regions, providing information and financial support for the development of this area of regional development.

A new lithostratigraphic framework and unified nomenclature for the Nsuze Group of the Nkandla sub-basin, southern Kaapvaal Craton, South Africa
Authors: Hicks N. , Gold D.J.C. , Ncume M. , Hoyer L.
Published: July 2021

During the early 20th century the term Insuzi Series, later reclassified as the Nsuze Group of the Pongola Supergroup, was proposed for a volcano-sedimentary succession exposed in the upper Nsuze River valley in central KwaZulu-Natal, South Africa. Subsequently, however, there has been little consensus on lithostratigraphic frameworks within the type area, and limited correlation with the exceptionally well-defined stratigraphy within the main Pongola basin. Recent mapping, combined with newly acquired high-resolution aeromagnetic data, satellite imagery, and available published geochronological data suggest that previously published schemes within the Nkandla sub-basin require revision. Utilising important regional marker units, as well as the stratigraphic positions of distinct sedimentary facies within the otherwise volcanic Nsuze Group, a working model is proposed. Lithostratigraphic units are well represented in the Mhlatuze and Nkandla inliers with examples from these areas given prominence. Where exposed, potential correlates within the Nsuze nappe complex are discussed. Within the proposed scheme the siliciclastic Mantonga Formation forms the base of the Nsuze Group, nonconformably overlying basement granitoids of the Kaapvaal Craton within the Mhaltuze Inlier. Mafic volcanics of the Nhlebela Formation overlie the Mantonga Formation in the inlier. These two lower units are, however, not exposed elsewhere in the sub-basin. The sedimentary White Mfolozi Formation forms the base of the succession in the Nkandla Inlier. Diamictites and stromatolite-bearing carbonate lithologies unique to this unit are utilised for regional third-order correlations with the type-area in the White Mfolozi Inlier. Mafic volcanics of the Agatha Formation overlie the White Mfolozi Formation in all exposures, but are most extensively developed within the Mdlelanga syncline of the Nkandla Inlier. Sedimentary and volcaniclastic lithologies of the Mkuzane Formation cap the Nsuze Group in the Mhlatuze and Nkandla inliers. Thickness of this formation is, however, highly variable having been subjected to pre-Vutshini Formation erosion. Through detailed reinterpretation of the stratigraphy of the Nkandla sub-basin we present a third order, (formation) scale, lithostratigraphic scheme encompassing all the formational units of the currently accepted stratigraphy within the main Pongola basin. This working model has the potential for lower-ranking units to be identified and be placed at their appropriate stratigraphic levels in future.

Published: July 2021

Objectives:

Peritoneal fluid cytology is done routinely in cases with serous carcinoma of ovary. However, morphologic features of borderline serous tumors (BSTs) of ovary in ascitic fluid have been rarely described. The aim of our study was to evaluate the morphologic features of BST with and without ascitic fluid involvement (BST+ and BST-, respectively) and compare with those of serous carcinomas, both in conventional and liquid-based cytology (LBC) smears.

Material and Methods:

Out of 30 BST cases reported in 3 years, seven cases had BST+. We compared the cytomorphology of seven cases of BST+, seven cases of BST-, and seven cases of serous adenocarcinoma with positive ascitic fluid cytology. Both conventional and LBC smears were studied in all cases and compared. Histopathology of omentum in these cases was also studied.

Results:

Most cases with BST+ had regular papillary fragment borders with nuclei showing mild-to-moderate pleomorphism, fine nuclear chromatin with small nucleoli as compared with serous carcinomas all of which had irregular borders with moderate-to-severe nuclear pleomorphism, coarse chromatin, and macronucleoli.

Conclusion:

A combination of cytoarchitectural and nuclear features can help in suspecting BST in ascitic fluid. Ascitic fluid cytology together with tissue histology can increase the rate of the detection of peritoneal implants.
Cervical spine computed tomography motion artifact mimicking spine injury in a patient with severe head injury
Authors: Okunlola Abiodun Idowu , Abiola Paul Olukayode , Babalola Olakunle Fatai , Achebe Chijioke Cosmas
Published: July 2021

Background:

Craniocervical CT scan is an essential part of the routine evaluation of patient with moderate and severe head injury to rule out associated cervical spine injury. Computed tomography motion artifacts can affect clinical decision making. The aim of this report is to emphasize that motion artifact still exists despite advance in technology and this can pose clinical challenge.

Case Description:

A 20-year-old man presented to our facility with severe head injury GCS 8. Craniocervical CT scan reported 75% C3 on C4 anterior subluxation and urgent spinal stabilization surgery was recommended. A static lateral cervical spine X-ray showed normal bony alignment. He was successfully managed and dynamic studies after recovery were normal.

Conclusion:

Cervical spine CT motion artifact can lead to unneeded surgery but routine clinical evaluation and cervical spine static and dynamic X-rays may be sufficient to resolve the puzzle.
An investigation of craniocervical stability post-condylectomy
Authors: Fiani Brian , Jarrah Ryan , Sarno Erika , Kondilis Athanasios , Pasko Kory , Musch Brian
Published: July 2021

Background:

Occipital condylectomy is often necessary to gain surgical access to various neurological pathologies. As the lateral limit of the craniovertebral junction (CVJ), partial condylectomy can lead to iatrogenic craniocervical instability. What was once considered an inoperable location is now the target of various complex neurosurgical procedures such as tumor resection and aneurysm clipping.

Methods:

In this study, we will review the anatomical structure of the CVJ and provide the first comprehensive assessment of studies investigating craniovertebral stability following condylectomy with the transcondylar surgical approaches. Furthermore, we discuss future considerations that must be evaluated to optimize the chances of preserving craniocervical stability postcondylectomy.

Results:

The current findings postulate upward of 75% of the occipital condyle can be resected without significantly affecting mobility of the CVJ. The current findings have only examined overall dimensions and have not established a significant correlation into how the shape of the occipital condyles can affect mobility. Occipitocervical fusion should only be considered after 50% condyle resection. In terms of indicators of anatomical stability, components of range of motion (ROM) such as the neutral zone (NZ) and the elastic zone (EZ) have been discussed as potential measures of craniocervical mobility. These components differ by the sense that the NZ has little ligament tension, whereas the EZ does represent ROM where ligaments experience tension. NZ is a more sensitive indicator of instability when measuring for instability postcondylectomy.

Conclusion:

Various transcondylar approaches have been developed to access this region including extreme-lateral and far-lateral condylectomy, with hopes of preserving as much of the condyle as possible and maintaining postoperative craniocervical stability.

Peristylus goodyeroides is a terestrial orchid that scattered around Southeast Asia. Morphological characters of P. goodyeroides can vary, depending on the ecological factors and habitat. Cytological characters in the form of chromosome configurations can be used as a taxonomic tool for the process of identifying and understanding variations in taxa. The purpose of this study was to determine the morphological characters and chromosome configuration of the P. goodyeroides from Curug Setawing, Kulonprogo. The method used was morphological characterization and plant chromosome preparation by squash method with the main steps of fixation, maceration, staining and observation. Data were analyzed with the help of Image raster 3, Corel Draw X7, and Microsoft Excel 2013. P. goodyeroides from Curug Setawing has the morphological characters of root tubers, cylindrical stems, ovate leaf shape, convolutive leaf arrangement and creamy white flowers. The orchid has a number of chromosomes 2n = 10 with a karyotype formula of 2n = 2x = 8m + 2t. Metacentric chromosomes are found on chromosomes 1-8 and telocentric chromosomes 9-10. The absolute arm length of the chromosomes has a range of 2.03-3.44 μm, the relative arm length of the chromosomes is 2.21-3.32 μm, the length of the p arm is 1.13-1.58 μm and the q arm is 1.23-2.12 μm.
Critical review on role of Microbiota transfer therapy in Autism spectrum disorder
Authors: Hemalakshmi R  , Pavithra Amritkumar
Published: July 2021

Autism spectrum disorder (ASD) is a developmental disorder that affects behaviour and communication. It can be diagnosed at any age, although the symptoms generally appear in the first two years of life. Autism is also known as a "spectrum" disorder because there is wide variation in the severity and type of patient experience. Intestinal dysbiosis remains a risk factor for several neuron-developmental disorders and physiological diseases such as ASD. The gut microbiome in human influence the total metabolomic profile and thus has an impact on the overall health of human. The brain-intestinal axis concept demonstrates the interaction between the brain and the diverse gut microbial population. Recent findings show that ASD symptoms in affected individuals are linked with the altered intestinal microbiome. The current treatment modality for the symptoms of ASD are limited to Applied Behaviour Analysis (ABA) and FDA approved medications like Risperidone and Aripiprazole. Individuals with ASD appear to be susceptible to adverse effects of these medications. Current accumulating studies indicate that Microbiota Transfer Therapy (MTT) is a promising technique for treating ASD. MTT involves in vitro batch culture of gut microbiota, which is viewed as a quick and accessible method. It has provided encouraging results by improving ASD-related gastrointestinal (GI) and behavioural symptoms in affected individuals. The present review focuses on the link between gut dysbiosis and ASD, analyses the available clinical studies related to various treatment options and describes the role of MTT as a promising therapy of bringing back the healthy gut microbiota composition in treating ASD.

Welcome Home, Prodigy
Authors: Stephens Murdoch
Published: July 2021

Drawing from the author’s childhood confusion over whether ‘prodigal’ means profligate or prodigious, this intervention anticipates the politicisation of returning New Zealand citizens. Written during lockdown, the intervention contrasts predictions of a great repatriation and pundits’ nationalistic revelling in the country’s success at containing the virus with the history of the ‘coming home’ essay and song. Stephen’s argues for a pre-consideration of the emotional states that might be provoked by the returnee. That pre-consideration is aimed at drawing the returnee into the collective, not for the sake of an enlarged spirit of the nation, but for the advancement of Left collective action.

Published: July 2021

O município de Minaçu, na região norte do estado de Goiás, difere de muitos municípios brasileiros pelas intensas alterações ocorridas em seu território. O município é conhecido como a capital brasileira do amianto, minério que deu origem a ocupação da região, cuja extração já dura seis décadas. Além das grandes cavas abertas pela atividade mineratória, o município ainda conta com duas usinas hidrelétricas, bem como parte de seus respectivos reservatórios, que cobrem boa parte de suas terras. O objetivo desse estudo foi analisar o uso e cobertura do solo entre os anos de 1988 e 2018 de Minaçu. Para tanto, foram empregados os dados de uso do solo do projeto MapBiomas, utilizados também para análise da conversão entre as classes do mapeamento do ano inicial para o final do período de análise. As classes menos expressivas para o período em análise foram área não vegetada, mineração, infraestrutura urbana e floresta plantada. As áreas de vegetação natural, como florestas e savana, foram convertidas para áreas de uso antrópico, principalmente pastagem, além de terem também as maiores áreas inundadas pelos dois reservatórios de usinas hidrelétricas presentes no município. Os dados utilizados possibilitaram um estudo eficiente e de baixo custo, que serve de base para uma maior compreensão da dinâmica do uso e cobertura, servindo ainda como base ao planejamento da ocupação sustentável do solo.

Se mencionan los intentos fallidos del ser humano conciente desde 1972 (la Declaración de Estocolmo) al tratar de buscar salidas a los problemas ambientales y enfatizan los intereses de los conglomerados superpoderosos como obstáculos al progreso del desarrollo sustentable. Se mencionan los indicadores de sustentabilidad y también los índices con énfasis sobre la estimación de los factores de educación, salud, pobreza, medioambiente e ecología. Se define el concepto de la biodiversidad y los modelos matemáticos de uso actual para su estimación.Key words: Development, ecology, economy, politics, socialAbstract. The basic philosophy, notions and concepts of sustainable development are laid out and the socioeconomic, political and ecological disasters that threaten the entire humanity are stressed. The huge differences among the developed, poor and developping countries are cotrasted. The failed intents of the conciencious man, since the Declaration of Stockholm (1972), in search of solutions to the environmental problems are pointed out, and the interests of the superpower conglomerates as a hinderance to the advancement of the sustainable development are mentioned. The indices of the sustainable development are mentioned with a particular emphasis on the estimation of some factors such as the education, health, poverty, the enviroment and the ecology.

Palabras claves: Algoritmos genéticos, logística de ruteo, metaheuristicas, secuenciaciónResumen. En la solución de problemas combinatorios, es importante evaluar el costo-beneficio entre la obtención de soluciones de alta calidad en detrimento de los recursos computacionales requeridos. El problema planteado es para el ruteo de un vehículo con entrega y recolección de producto y con restricciones de ventana de horario. En la práctica, dicho problema requiere ser atendido con instancias de gran escala (nodos ≥100). Existe un fuerte porcentaje de ventanas de horario activas (≥90%) y con factores de amplitud ≥75%. El problema es NP-hard y por tal motivo la aplicación de un método de solución exacta para resolverlo en la práctica, está limitado por el tiempo requerido para la actividad de ruteo. Se propone un algoritmo genético especializado, el cual ofrece soluciones de buena calidad (% de optimalidad aceptables) y en tiempos de ejecución computacional que hacen útil su aplicación en la práctica de la logística. Para comprobar la eficacia de la propuesta algorítmica se desarrolla un diseño experimental el cual hará uso de las soluciones óptimas obtenidas mediante un algoritmo de ramificación y corte sin límite de tiempo. Los resultados son favorables.Key words: Genetic algorithms, routing logistics, metaheuristics, schedulingAbstract. In an attempt to sovle the combinatorics problems, it is important to evaluate the costbenefit ratio between obtaining solutions of high quality and the loss of the computational resources required. The problem presented is for the routing of a vehicle with pickup and delivery of products with time window constraints. This problem requires instances of great scale (nodes≥100). A strong active time window percentage exists (≥90%) with factors of amplitude ≥75%. The problem is NP-hard and hence, the application of an exact method of solution, is limited by the time frame required for routing activity. A specialized genetic algorithm is proposed, which offers solutions of high precision and in computational times that makes its practical application useful. An experimental design is developed with good results that makes use of optimum solutions obtained by means of branch and cut algorithm without time limit.

Published: July 2021

Abstract. Today protectionist actions have been highly adopted by the nations, that in order to cope with the constant crises that threaten to slow economic growth. The cancellation of trade agreements has led to a strategic management restructuring, which now seeks to minimize the negative effects. Mexico is not the exception, because last year suffered the imposition of a series of protectionist guidelines by Brazil and Argentina, which were intendedto reduce the number of exports that are made to these South American economies. This study intends to analyze the impact and strategic changes adopted by Mexico in the automotive industry as a result of these regulations. Using a method of analysis of quantitative and qualitative data is to estimate the damages to the sector as well as the measures taken by Mexico to decrease side effects.Keywords: automotive industry, international trade, institutions based view, protectionismResumen. La adopción de medidas proteccionistas en el ámbito de las relacionescomerciales ha ocasionado una reestructuración en la gestión estratégica, la cual ahora busca minimizar los efectos negativos en las economías. México no ha sido la excepción, debido a que el año pasado sufrió la imposición de una serie de lineamientos proteccionistas por parte de Brasil y Argentina, las cuales tenían como objetivo disminuir el número de exportaciones del sector automotriz que se realizan a dichas naciones sudamericanas. La presente investigación busca analizar el impacto en la balanza comercial y los cambios  estratégicos adoptados por México dentro de la industria automotriz como resultado de estas regulaciones. Se asume la hipótesis de la existencia de afectaciones dentro del sector, por lo que utilizando un método de análisis de datos estadísticos se busca medir el impacto de estas medidas en el desempeño comercial, así como las estrategias adoptadas por México para disminuir los efectos adversos.Palabras clave: comercio internacional, industria automotriz, proteccionismo, visión basada en las instituciones
