The Israeli Law’s Attitude Towards Minors’ Rights of Participation in Making Decisions Relating to Them
Authors: Khawaly-Esawi Rita K
Published: December 2020

The purpose of the paper is to examine the attitude of Israeli law towards minors’ participation in making decisions relating to them. This right is expressed in the United Nations Convention on the Rights of the Child which has turned into an international document approved by nations all over the world. The minor’s right to participate in decisions relating to him is enshrined in Section 12 of the United Nations Convention on the Rights of the Child. It is possible to see that the convention recognized the dignity of the person and the human rights of the minor. However, it is willing to grant rights to minors taking into consideration their age and their different stages of development. Sometimes parents focus mainly on their own interest and rights, and thus find it hard to faithfully determine their children’s rights and protect their best interest. If a minor does not have the right to participate in legal proceedings relating to him, he might get hurt. The view which accepts the notion of independent representation of a minor stems from the concept that a minor has rights like adults, and those rights include one to independent representation. Such a right can be practiced when the minor himself, his guardian or lawyer, represents his interests independently from his parents. Israeli law generally does not provide minors with independent rights such as the right to be a part of decision making. However, it does provide minors with rights in specific cases which might be seen as necessary, and there is still considerable space for the personal worldview of the judge. In addition, Israeli law is yet to adequately define the exact role of the legal guardian representing a minor and his methods of operation, and nowadays this duty depends on the personality of a legal guardian and his approach to this duty.

Published: December 2020

This article deals with the issues of early motherhood. Early parenting is a critical event in the life of teenage girls. Teens are mentally and socially immature and unprepared to fulfill the role of mother. Besides minor mothers usually come from poor families, are pupils in primary or secondary schools, do not work, do not have a steady income and own apartment, and in this case remain under the custody care and educational institution. The article is an attempt to answer the question, as teenagers from disadvantaged groups, pupil of childcare centers and describe the experience of motherhood. What is surprising, despite initial concerns and difficulties in retrospect evaluate them as a gift and a blessing, a source of valuable life experience and even a protective factor against the occurrence of other problems care and education.
The Model of Professional Development School (PDS) as a Practice of Partnership University-Schools in Teacher Education: A Multi-year Evaluation Study in Israel
Authors: Bar Nava
Published: December 2020

The article presents in its first part the partnership model – PDS (Professional Development School) for teacher education that developed in the 1970s in the United States following criticism and re- search findings that indicated lack of satisfaction with the traditional teacher education programs. In its second part the article presents findings and discussion of a multi-year study conducted over seven years, from 2010 to 2016, in the first and up till now the only PDS partnership incorporated into teacher training program in research university in Israel. The multi-year study focused on stu- dent teachers’ evaluation of the contribution of the teacher training components of the university- school partnership model (PDS) to their learning of teaching: the practice teaching in the school and the school mentors; the groups of student colleagues as learning communities and their weekly meetings and the university coordinators. From the perception of the PDS partnership as a dynamic and developing process and from the approach of evidence-based practice, the importance of this multi year study lies in the identification of the essential strengths in the process of the practical experience expressed in the partnerships for their empowerment. In addition the importance of this research is in the identification of the essential weaknesses and challenges, for the purpose of en- quiry and learning in the learning communities who take part in the PDS partnerships, and the rais- ing of the necessary courses of action and changes. The importance of the research study in the in-ternational aspect lies in the presentation of an additional profile of partnership for the extension of the shared discussion about dilemmas and challenges that arise from the implementation of different partnerships in the training of teachers.
Dziecko w przestrzeniach języka ojczystego – wybrane aspekty
Authors: Kuszak Kinga
Published: December 2020

The article discusses various spaces of children’s linguistic functioning and the wealth of linguistic experiences available in each of them. The author points to the fact that each of these spaces provides children with different vital experiences. The starting point for the reflections on the spaces of native language is Ferdinand de Saussure’s concept of speech as a human ability and language as a set of forms of speech uses. The term “linguistic space” and the criteria for determining a space were adopted from the works of Kwiryna Handke who emphasized that language, as an integral structural component of social space and the community that uses it, plays two roles in this space: it reflects the community’s perception of its surroundings and provides help and basic tool for shaping the space. Therefore, the forms of language use differ according to the spaces, situations and roles which one encounters. The next part of the paper presents selected vocabulary that children may potentially acquire in the following spaces: family, kindergarten (school), peer group, via Internet communication, as viewers of TV commercials and readers (recipients) of literature. The summary presents the spaces of children’s linguistic functioning in the form of a chart, taking into account the roles adopted by children in each space, places and situations distinctive of the space, as well as the words, expressions, and language tools typical for each space.
Kultura organizacyjna szkoły integracyjnej w zwierciadle kultury pogranicza
Authors: Zenon Gajdzica Zenon Gajdzica
Published: December 2020

The thesis is put forward in the presented article that the organizational specificity of integrated education creates a unique culture with some characteristics of typical borderland. Integrated school is a place where the dominating and the subordinated culture clash and/or collaborate. Depending on the precisely specified assumptions, beliefs, the recognized values and norms (consolidated within the institutional knowledge of a particular school), two different cultures of integrated school can be formed. These cultures are shaped by two types of social practices and two different models of the functioning of school. The study is aimed at a preliminary attempt to specify these models. They are assumed to comprise a set of notions which constitute analytical categories useful in describing the daily routine of school. Moreover, these models may become a tool for interpreting and understanding the states, processes and features of some elements of school and their interrelations.
Husserlowski świat życia codziennego i jego znaczenie pedagogiczne
Authors: Gara Jarosław
Published: December 2020

The world of everyday life was for Husserl the most original expression of the "radical beginning" of human experience and the accompanying senses and meanings. It is a world limited by time-space, one to which we all belong, together with our traditions, habits and interests. Whatever happens in the horizon of the world of everyday life thus relates to ourselves, because it is the world of the living organisms – and these can experience joy and fear, can work and rest, attack or flee, expect, await or desire something. In this sense, it is the world dialectically interpenetrating contradictions and aporias. It is a world where what is limited and unlimited, physical and spiritual, ordinary and extraordinary are intertwined, but also in an a priori manner are determined by the specific relationships between them. From this point of view, there are three basic general relationships which allow to classify and clarify the pedagogical principles: 1) what is infinite in the finite, 2) what is cultural in the natural, 3) what is extraordinary in the ordinary. Experiencing the world of everyday life remindsus, after all, that the infinite, the spiritual, the extraordinary is de facto encompassed by and found in what is finite, physical and ordinary.
W poszukiwaniu eklektycznego paradygmatu edukacji głuchych
Authors: Tomaszewski Piotr , Moroń Ewelina
Published: December 2020

In recent years, changes in the approach to deafness and, hence, in the education of the deaf and hard of hearing have been occurring around the world, including Poland. Deafness is increasingly perceived as a sociocultural phenomenon and not merely as a medical one, while sign language is seen as a natural language that can be used in deaf schools and by large numbers of d/Deaf people. Nevertheless, it seems at present that both deafness models are incompatible with each other for ideological reasons although they are concurrent, the medical model being dominant and the sociocultural one being alternative. For that reason, both the d/Deaf community and the deaf education still contend with significan problems related to the language policy, discrimination based on deafness (audism), sign language (linguicism), disability (ableism) or the specificityof conflictsamong the d/Deaf themselves (deafism).All this will be illustrated in this paper, along with suggested possible solutions.

Published: December 2020

The category of trust has been considered in numerous philosophical, sociological, psychological, economic, legal, and educational deliberations. The issue of whether trust occurs in or is absent from human relationships has been widely discussed in the social discourse and has been a component of social capital of organisations.This paper reviews interdisciplinary literature to characterise and describe the phenomenon, identifying its dimensions, types, and patterns. It focuses on interpersonal trust as a factor characterising the functioning in organisations, also with reference to educational institutions. The author also identifiestrust in the context of helping relationships in which it is a component of the contractforming process between those who provide and those who use help, of establishing and developing relationships.
Rozwiązywa(nie) zadań tekstowych – stare wyzwania i nowe potrzeby edukacji wczesnoszkolnej
Authors: Nawolska Barbara , Żądło-Treder Joanna
Published: December 2020

Every human needs the ability to solve problems. In early childhood education, the development of this skill can and should be implemented by solving text tasks. Meanwhile, according to a variety of analyses, a significant number of students are unable to solve these tasks. This is most likely the result of insufficient mathematical competencies of teachers in early school education and related teaching errors, mainly involving calculating exercises and solving tasks according to patterns. At the same time, students who are in fact unable to solve tasks but only limit themselves to the use of learned patterns, in non-standard task situations (not practiced at school) do quite well.

RECONHECIMENTO: UMA FORMA DE JUSTIÇA OU DE AUTORREALIZAÇÃO?
Authors: Dos Santos Sergio Baptista
Published: December 2020

O objetivo deste artigo é analisar e comparar os modelos de reconhecimento dos filósofos Charles Taylor (1931), Axel Honneth (1949) e da cientista política Nancy Fraser (1947), a fim de avaliar os limites e as possibilidades de cada uma dessas visões sobre esse modelo de justiça. As lutas por reconhecimento, diferentemente das lutas por “redistribuição”, não têm como orientação normativa, em primeiro plano, a eliminação das desigualdades econômicas, mas o combate ao preconceito e a discriminação de determinados grupos e indivíduos, tendo em vista que a negação do reconhecimento causa danos subjetivos, constituindo-se numa forma eficaz de opressão. Para Fraser (2007), o reconhecimento concebido como autorrealização das identidades de indivíduos ou grupos tende a inviabilizar a construção de um paradigma de justiça que englobe, simultaneamente, reconhecimento e redistribuição. Por isso, elabora um modelo de reconhecimento que tende a promover a paridade participativa sem estar baseado na autorrealização. No entanto, contrariando Fraser (2007), apesar dos modelos de reconhecimento de Taylor (2000) e Honneth (2003) estarem baseados ao processo de formação das identidades, eles não são incompatíveis com luta por redistribuição.

Authors:   Institute of Europe, Russian Academy of Sciences, Nosov Mikhail
Published: December 2020

At present time, there are three main international integration projects actually operating in the Eurasian space ‒ the European Union (EU), the Eurasian Economic Union (EAEU) and the Chinese “Belt & Road Initiative” (BRI) project. All three differ in the time of their beginning, in economic and political possibilities, in methods of implementation and in its goals. All projects, one way or another, interact with each other in Eurasia with different intensity, potentially open up wide opportunities for them, but also create new problems. For Russia relations with China is one of the most important factors of its foreign policy and the Chinese project is a substantial part of it. The article examines the history of the Chinese project, the reasons for its occurrence, and the problems arising in bilateral and global relations in the context of Russia’s participation in it.

Published: December 2020

Magnesium alloy usage in manufacturing engineering components resulting in weight reduction and as a consequence, reduction in fuel and energy consumption. Magnesium has a relatively low density and roughly 30% lighter than aluminum. However, magnesium is considered to be difficult to deform because of the HCP structure. In this present work, the effect of semi-solid forming temperature and heat treatment on mechanical properties of Mg-Al-Zn were investigated. Mg-Al-Zn ingot was machined into a billet and formed with three different temperatures and underwent T4 heat-treatment process. To determine the mechanical properties and microstructure of the magnesium alloy, tensile and hardness test were performed and the result indicates that the highest average maximum tensile stress was achieved at 209 MPa at 530ºC after forming with T4 heat treatment and highest hardness value was at  21.44 HRB at 560ºC. On the other hand, effect of the forming temperature gives impact to the evolution of the microstructure from large grain size (as-cast) to the smaller grains size (0.00797mm2) forming at 560°C. This relate to the extensive dynamic recrystallization (DRX) occurs during forming and Mg-Al-Zn was sensitive with heat either direct or indirect heating method.
Numerical analysis on the use of multi-element blades in a horizontal-axis hydrokinetic turbine
Authors: Aguilar Jonathan , Velásquez Laura Isabel , Rubio Clemente Ainhoa , Chica Edwin
Published: December 2020

The blades of a hydrokinetic turbine have a great impact on its performance due to they are the elements responsible for capturing the kinetic energy from water and transform it into rotational mechanical energy. In this work, numerical analyses on the performance of a multi-element blade section were developed. The lift and drag coefficients (CL and CD, respectively) of the hydrofoils with traditional and multi-element configurations were studied. For this purpose, 2D numerical analyses were conducted by using JavaFoil code. S805, S822, Eppler 420, Eppler 421, Eppler 422, Eppler 423, Eppler 857, Wortmann FX 74-CL5-140, Wortmann FX 74-CL5-140 MOD, Douglas/Liebeck LA203A, Selig S1210, Selig S1223 and UI-1720 profiles were tested. The results indicated that the Eppler 420 multi-element hydrofoil provided high efficiency to the turbine. This was attributed to its higher relationship between the maximum CL and CD (CLmax /CD), which was equal to 47.77, compared to that of the Selig S1223 profile (39.59) and other hydrofoils studied. Therefore, the final optimized blade section selected was an Eppler 420 multi-element hydrofoil with a flap chord length of 70% of that of the main profile. The hydrodynamic and structural designs of the optimized blade section were validated with detailed 3D numerical models, through ANSYs Fluent software. The fluid and structural domains were connected using one-way coupling. The influence of the blade geometry and the operational parameters on the stresses supported by the blades were found by analyzing the fluid-structure interaction. From the numerical analyses conducted, it was observed that the blades did not exhibit structural fails. In this regard, the multi-element hydrofoil might be used for the design of a horizontal-axis hydrokinetic turbine with a high efficiency.

Application of woven fabric kenaf fibers in production of polymeric composites (known as woven fabric kenaf reinforced composite (WKRP)) were readily available in the literatures due to excellent tensile strength and elongation at break. Nevertheless, there are less reported work and information regarding to performance of these materials in bolted joints problem. Bolted joints demonstrate complicated damage morphologies either net-tension, shear-out or bearing failure modes dependence upon combination arrays of lay-up/joint variables. XFEM approach has been reported in the literature, yet the agreements are limited to net-tension failure resulting from stress concentration problem. The aim of this paper to carry out strength prediction work of single-lap WKRP/aluminium bolted joints by using Hashin formulation within 3D finite element framework. Hashin formulation which based on ply-by-ply basis seen to perform better prediction to bearing failure modes. The material properties incorporated within Hashin formulation was taken from a single-ply of woven fabric. Strength prediction from Hashin formulation showed a difference of less than ±25% in net tension-bearing failure mode, but less good predictions (some lay-up showed discrepancies of 50%) in smaller W/d to give net-tension mode. Good prediction in net-tension-bearing failure were exhibited in Hashin formulation than XFEM approach as bearing failure is based on ply-by-ply basis due to fiber kinking and matrix compression.

Presence of fibers and fillers in a composite can be an efficient way to arrest crack either at macro or micro levels. In this work, woven jute and carbon fibers were arranged alternately in PLA (Polylactic Acid) nanocomposite. Graphene or nanoclay was embedded into PLA matrix to make polymer nanocomposite. Fiber reinforced polymer nanocomposites were prepared by varying the concentration of graphene or nanoclay in the PLA matrix and alternate woven jute/carbon fibers was then bind with the PLA nanocomposite. Influence of graphene or nanoclay concentration and presence of woven fibres in the composite was quantified by flexural analysis. Flexural strength and flexural modulus were found to increase at 3wt% of nanofiller concentration for both graphene/jute/PLA and nanoclay/jute/PLA nanocomposites with increment up to 37% and 31%, respectively. FTIR was used to determine the interaction between PLA and nanofillers. Morphology observation by Scanning Electron Microscopy (SEM) was done to investigate the fractured surface of the hybrid jute/carbon fibres reinforced PLA nanocomposite.
Using computational fluid dynamics to predict the erosion rates on the cyclones wall for coal boiler plant
Authors: Anindito B. , Nurtono T. , Winardi S.
Published: December 2020

In the industrial coal boiler, cyclone is used to separate the silica sands (as fluidizing medium) from the furnace combution gas. A gas-solid separation system with turbulent swirling flow that occurs in the cyclone will cause erosion on the cyclone wall. The erosion will cause a decrease in the cyclone performance and increase the maintenance cost. CFD simulation was conducted to predict this erosion using industrial cyclone in the coal boiler industry on its actual dimensions. The dimensions were 5120 mm in diameter and 13970 mm in height. It was performed using the Reynolds Stress Model (RSM) for turbulence flow in the gas phase and the Oka erosion model. The erosion rate on the cyclone wall was investigated at various gas inlet velocity and solid rate. The inlet velocities ranged from 6 to 8 m/s and the solid rates ranged from 30 to 40 kg/s with silica sands as solid particles (0.075 and 1.5 mm in diameter). At the selected local area, the results showed that the higher gas inlet velocity for the same solid rate would increase the erosion rate (about 25%). However, the higher solid rate for the same velocity will also increase the erosion rate on the cyclone wall (about 18%). These results indicate that cyclone wall errosion are significantly affected by inlet gas velocity.

The change of the spinal curvature in completing a variety of daily tasks is essential to independent living. There is still a lack of studies highlighting the lumbar segmental contribution during sit-to-stand (STS) and stand-to-flexion (STF) using non-invasive study. The purpose of this study is to compare the spine kinematics by defining lumbar as a single and multi-segmental during continuous daily motion in healthy Asian adults using a non-invasive approach. During STS, most subjects implemented kyphotic lumbar curve during the early stage of motion which revealed poor posture implementation and significant differences in the lumbar kinematics which were only noticeable at specific phases between both approaches. A significant difference in multi-segmental behaviour was observed only at the end of the motion. All three segments displayed different time responses during the transition from kyphotic to lordotic curve. Passive/delayed behavior within the lower lumbar segment was observed between 0-50% of motion completion. During STF, statistically significant differences were found between assuming lumbar as a single and multi-segment in all phases. This in vitro study identified characteristic motion patterns in the lumbar spine during daily motions. The results provided a clear description of the healthy spinal condition of adults and may serve to identify specific multi-segmental contribution.
eTep-retromuscular Repair for Ventral Hernia; a Technique Closest to Ideal
Authors: Mitevski Aleksandar , Markov Petar
Published: December 2020

Introduction. Ventral hernia represents a problem for the surgeon and patients alike. eTEP repair is a technique that is minimally invasive, provides lower overall complication rates, decreased wound complications and the recurrence rates and shortens the length of stay in the hospital. Case. We present a case of a 48 year old patient who was admitted to our hospital for elective treatment of recurrent umbilical hernia. The patient had umbilical hernia repair 4 years ago, suture repair without mesh placement was performed according to the information given by the patient. On inspection there is visible supraumbillical scar, 12 cm in length with hernia bulging under the scar which is partially reducible on pressure. Discussion. The eTEP technique is closest to ideal because the abdominal cavity is not penetrated, is lessening the risk of visceral lesions and trocar site hernias, allows local or regional anesthesia, gives unsurpassed views of inguinal region and hernias and reproduces the technique of Rives-Stoppa. In favor to overcome the limitations deriving from the limited surgical field and restricted port set up, this technique has been modified based on the normal anatomy of the abdominal wall naming it depen­dently of the extension of the dissection and the location of the hernia. Conclusion. The extended-TEP (e-TEP) technique is based on the anatomical principle that the extraperitoneal space can be reached from almost anywhere in the anterior abdominal wall. It provides the most of the benefits for the patients but also requires great surgical skill and understanding of the anatomy of the anterior abdominal wall.
Observaciones críticas acerca de «Natural Law and Natural Rights», de John Finnis
Authors: Martínez-Valls Néstor
Published: December 2020

Tras seleccionar algunas tesis capitales de Natural Law and Natural Rights, de Finnis, se analiza críticamente la aceptación de la «ley de Hume» por parte del autor, y también, la separación resultante entre la razón práctica y la razón especulativa, la falta de distinción entre el nivel especulativo propio de la filosofía moral y el nivel práctico propio de la decisión individual, la tesis del conocimiento de la naturaleza humana a partir de los principios de la razón práctica, y el intento de reducir la naturaleza humana a la racionalidad, como fundamento de la ley natural; la insuficiente explicación de la obligación moral por las exigencias del bien común, y de la existencia de actos intrínsecamente malos, la negación de un único fin último para todos los hombres, la negación del carácter moral del primer principio de la razón práctica, y la reducción de la tesis del fundamento divino de la obligación moral a un mero voluntarismo.
El significado de «derecho» y el concepto de derecho
Authors: Rodríguez-Toubes-Muñiz Joaquín
Published: December 2020

John Finnis defiende en Natural Law and Natural Rights una investigación conceptual y práctica del derecho que identifique su caso central y rechaza los intentos de formular un concepto común a teorías jurídicas descriptivas rivales. Este estudio cuestiona ese enfoque metodológico y argumenta que formar un concepto neutral de derecho es un objetivo teórico sensato e importante; y que el significado común de la palabra «derecho» es un punto de partida viable para alcanzarlo. El método del caso central es inadecuado para una teoría jurídica descriptiva porque aplica una interpretación de dicha centralidad surgida de una concepción determinada del derecho; y excluye que pueda tener el valor negativo descrito por otras concepciones rivales. El método del caso central sería idóneo si el derecho fuera un fenómeno específico descrito y bautizado en el pasado y que es ahora la referencia precisa de «derecho». Pero la prevalencia de desacuerdos teóricos hace esta hipótesis inverosímil y sugiere que el derecho es lo que los grupos humanos han venido reconociendo como tal históricamente, tal como se refleja en el uso de la palabra «derecho» y de sus equivalentes.
Los derechos humanos y el bien común. Una aproximación desde John Finnis
Authors: Cruz-Ortiz-de-Landázuri Luis-María
Published: December 2020

En su libro Ley natural y derechos naturales, Finnis establece un diálogo entre dos perspectivas o visiones en torno a la fundamentación de los derechos humanos: la clásica, que pone el acento en lo que es debido en una relación de justicia, y la moderna, que se centra en las personas que se benefician de esa relación.

A partir de ese diálogo de tradiciones jurídicas Finnis intenta, por un lado, ofrecer una fundamentación objetiva de estos derechos, ya que los enraíza en aquellos bienes básicos que constituyen las dimensiones centrales del perfeccionamiento humano y no en las preferencias subjetivas. Por otro lado, en la medida en que la realización de esos bienes sólo es posible en el contexto de una comunidad política, necesitan de facultades jurídicas para exigir de los demás miembros la prestación de determinadas acciones y omisiones.

We report the large-scale synthesis of highly luminescent ZnSe nanocrystals (NCs) by a simple and low-cost hydrothermal method. XRD (X-ray Diffraction) and HR-TEM (High Resolution Transmission Microscopy) characterization studies confirmed the formation of as-synthesized ZnSe NCs in cubic structure. The optical property of ZnSe NCs were tunable via controlling the Zn:Se molar precursor ratio (0.5:1–1.5:1), reaction temperature (150–200 0C), and reaction time (5–30 h). The resulting ZnSe NCs with the Zn:Se precursor ratio of 1:1, hydrothermally treated at 190 0C for 20 h exhibited the highest photoluminescence quantum yield obtained by PL spectra with the 355 nm excitation. The current–voltage (I–V) characteristics of the ZnSe NCs show its promising application in the solid-state lighting.
