Pedagogy and Education against the Collision of Ethoses
Authors: Kwieciński Zbigniew
Published: October 2020

The essay proposes a way to search for common educational goals in a situation marked by deep political and worldview-related divisions in Polish society. It recalls Kazimierz Sośnicki’s concept of the “collision of ethoses” conceived in the 1930s, and the need to overcome shallow ‘ceremonialism’ in order to move towards a deeper experience of values, both spiritually and through altruistic actions.
Education for Humanity – as the Message of the Older Generation of Teachers – In the Light of their Memoirs 2016
Authors: Dróżka Wanda
Published: October 2020

The article attempts to familiarise the reader with the memoirs of teachers compiled as a result of the third edition of the National Competition for memoirs and other autobiographical statements under the title “Teacher’s message: Generations of Polish Teachers for the Future” (2014–2016). In the light of the preliminary analysis of the texts submitted, an outline emerges of the mission that teachers would see for themselves, for their successors, and for education of the 21st century. It is something significant: the mission of protecting humanity for future generations, for preserving the world, for the survival of spiritual values confronted with consumerism, cybertechnology, and scientific progress on the basis of genetics, computer science, etc. Education appears in the light of these diaries as a space and a way to reinforce humanity, which is threatened from different sides. There are two approaches here, two concepts of education and training, and of the teacher’s role in this work, the more conservative and the more liberal. In general, it is a question of rational citizenship, the rational use of subjectivity and autonomy, which is similar to M. Nussbaum’s concept of remedying the citizenship crisis. This mission of education requires reflective, subjective and autonomous teachers, using discursive reflexivity (thinking about their own thinking), with an analytical attitude, respecting the requirement of interdependence, understanding the contemporary world, themselves and others. In turn, what this requires from teachers is deep knowledge, thorough education, a high level of culture, and humanistic, subjective and reflective changes in their education and professional development.
Women’s Academic Careers – Entanglements and Inspirations
Authors: Zaworska-Nikoniuk Dorota
Published: October 2020

In the article “Women’s Academic Careers – Entanglements and Inspirations”, I write about the significant problem of the specificity of female careers related to gender and its stereotypical perception. The purpose of the research was to analyse the individual stages of women’s academic careers in the academic field of pedagogy (humanities and social sciences) in 2013–2019, based on the latest research reports (E. Kulczycki Report and the ‘Science in Poland’Report). The study uses data about pedagogy as a feminized discipline, in which the majority of academic staff are female. The main research question was: How do the individual stages of women’s academic careers in social sciences (especially pedagogy) progress, and what factors determine them? The research method used in this study was what is often referred to in colloquial language as “desk research”, i.e. reviewing and analysing scientific literature, analysing data sources, compiling them and mutual verification. The interpretative background of this research was an analysis of the mechanisms of gender inequalities at universities (related to the mechanisms of the labour market).

Authors: Twardowski Andrzej
Published: October 2020

In recent years, increasing attention has been devoted to developing pedagogical approaches that are appropriate in heterogeneous classrooms. Teachers working in inclusive classrooms must develop forms of student work that do not isolate and stigmatize learners with special educational needs. In the first part of the article, the author analyzes the origin and essence of the idea of inclusive education. In the second part of the article, three forms of work organization for students in inclusion classes are characterized: Peer Tutoring, Cooperative Learning and Multi-level Teaching.
The Image of the Kindergarten Teacher in the Israeli Media
Authors: Alezra Fani
Published: October 2020

Recognition of the importance of early childhood education is increasing. Many reports published in Israel and around the world deal with the powerful and critical impact of this era on individuals and society. In contrast, the professional image of the kindergarten teacher in Israel is seen as being as low-status as in many countries. This professional image influences the choice of teaching profession and the conditions of admission in teacher training colleges. The low-status image is influenced by many publications in the Israeli media. To say these publications are unflattering to the profession and to kindergarten teachers would be an understatement. In this article, I will try to answer the question: How is the kindergarten teacher’s image expressed in publications about kindergarten and kindergarten teachers in the media in Israel? The research tools are ten articles with the kindergarten tag on the news content sites Walla and Mako as of June 2019. The method chosen is content analysis, a research technique for objectively describing media content through which messages can be identified. In so doing, I will draw conclusions about what can be done to improve publications about the profession and at the same time to improve the image of the kindergarten teacher in society.

Spinal cord herniation following multilevel anterior cervical discectomy and fusion: A case report and literature review
Authors: Sinha Siddharth , George K. Joshi
Published: October 2020

Background:

Anterior cervical discectomy and fusion (ACDF) is one of the most commonly performed spinal operations. Spinal cord herniation following these procedures is rare, more typically being described as occurring posteriorly rather than following anterior corpectomy and fusion (e.g., reported in four corpectomy cases). Here, we describe a case in which spinal cord herniation was attributed to a three-level ACDF.

Case Description:

A 31-year-old male initially presented with a 1 year’s duration of increasing myelopathy attributed to MR documented three-level disc disease (C4-C7). He successfully underwent a three-level ACDF without complications/durotomy. One year later, he again presented, with myelopathy (i.e., recurrent neck pain and stiffness) newly attributed to MR documented anterolateral C4-C5 cord herniation. As he declined further surgery, he was treated medically (e.g., utilizing analgesia and physiotherapy) and was no worse 6 months later.

Conclusion:

The occurrence of spinal cord herniation through a prior ACDF defect must be considered when patients present with recurrent myelopathy following previous ACDF surgery.
Late-onset occlusion of the Monro foramina after endoscopic third ventriculostomy in adults: Case discussion and review of the literature
Authors: Fabbro Sara , Tuniz Francesco , Piccolo Daniele , Cramaro Antonio
Published: October 2020

Background:

Few cases of adult idiopathic occlusion of the foramen of Monro (AIOFM) are described in the literature. The diagnosis of AIOFM after an endoscopic procedure is even more infrequent.

Case Description:

We described the case of a 50-year-old woman who developed bilateral membranous occlusion of both Monro foramina 20 years after an endoscopic third ventriculostomy (ETV) for triventricular hydrocephalus due to an aqueductal stenosis. The patient underwent an endoscopic treatment (left foraminoplasty and septostomy) to check the patency of the stoma on the floor of the third ventricle. After the endoscopic procedure, the symptoms improved and the postoperative magnetic resonance imaging (MRI) demonstrated the resolution of the biventricular hydrocephalus.

Conclusion:

Bilateral occlusion of both FM with consequent bilateral lateral ventricles enlargement is an extremely rare condition, especially if we consider the cases of biventricular hydrocephalus after endoscopic procedures. In our opinion, an endoscopic approach should be attempted as first choice procedure, avoiding any intraventricular stent or shunt placement.
“Whiplash” cervical trauma with fracture and migration of carotid stent fragments
Authors: Silva Danilo Almeida , Aguiar Guilherme Brasileiro de , Jory Maurício , Conti Mario Luiz Marques , Veiga José Carlos Esteves
Published: October 2020

Background:

Angioplasty using a carotid stent is a treatment modality for carotid stenosis, with results similar to those obtained with endarterectomy, as demonstrated by important studies. The increasing use of this procedure has also led to a larger number of reports of complications, stent fractures among those. Stent fracture is a rare manifestation and hence needs further studying so that its actual prevalence can be determined, as well as its associated risk factors and proper clinical management. The current study reports the case of a patient who had previously undergone angioplasty with a carotid stent and, after an automobile accident, presented with a stent fracture and distal embolization of fragments thereof with neurological manifestation.

Case Description:

A male patient, 40 years old, presented with a history of previously stent carotid angioplasty. He had been involved in an automobile accident and suffered a stent fracture with distal fragment migration. As he was an asymptomatic patient (NIHSS 0, Rankin zero), we opted for a conservative treatment with oral anticoagulant.

Conclusion:

Angioplasty is an effective treatment for extracranial atherosclerosis and, albeit rare, stent fractures can result in the migration of fragments thereof. This occurrence should be suspected in patients who have sustained severe neck injuries due to sudden deceleration and may be associated with thromboembolism.
Charge-Transfer Intermediates in the Electrochemical Doping Mechanism of Conjugated Polymers
Authors: Bargigia Ilaria , Savagian Lisa R. , Österholm Anna M. , Reynolds John R. , Silva Carlos
Published: October 2020

In this work, we address the nature of electrochemically induced charged states in conjugated polymers, their evolution as a function of electrochemical potential, and their coupling to their local environment by means of transient absorption and Raman spectroscopies synergistically performed in situ throughout the electrochemical doping process. In particular, we investigate the fundamental mechanism of electrochemical doping in an oligoether-functionalized 3,4-propylenedioxythiophene (ProDOT) copolymer. The changes embedded in both linear and transient absorption features allow us to identify a precursor electronic state with charge-transfer (CT) character that precedes polaron formation and bulk electronic conductivity. This state is shown to contribute to the ultrafast quenching of both neutral molecular excitations and polarons. Raman spectra relate the electronic transition of this precursor state predominantly to the Cβ -Cβ stretching mode of the thiophene heterocycle. We characterize the coupling of the CT-like state with primary excitons and electrochemically induced charge separated states, providing insight into the energetic landscape of a heterogeneous polymer-electrolyte system and demonstrate how such coupling depends on environmental parameters, such as polymer structure, electrolyte composition, and environmental polarity.
Mechanisms for Flavin Mediated Oxidation: Hydride or Hydrogen-Atom Transfer?
Authors: Curtolo Felipe , Arantes Guilherme M.
Published: October 2020

Flavins are versatile biological cofactors which catalyze proton-coupled electron transfers (PCET) with varying number and coupling of electrons. Flavin mediated oxidation of nicotinamide adenine dinucleotide (NADH) and of succinate, initial redox reactions in cellular respiration, were examined here with multiconfigurational quantum chemical calculations and a simple analysis of the wave-function proposed to quantify electron transfer along the proton reaction coordinate. The mechanism of NADH oxidation is a prototypical hydride transfer, with two electrons moving concerted with the proton to the same acceptor group. However, succinate oxidation depends on the elimination step and can proceed through the transfer of hydride or hydrogen-atom, with proton and electrons moving to different groups in both cases. These results help to determine the mechanism of fundamental but still debated biochemical reactions, and illustrate a new diagnostic tool for electron transfer that can be useful to characterize a broad class of PCET processes.

Chemoprevention of oral cancer using tretinoin biofilm- A review
Authors: Harini M  , Gheena S  , Gayathri R
Published: October 2020

Oral cancer is a major disease prevalent all over the world. Oral squamous cell carcinoma (OSCC) is a well-known disorder that accounts for more than 90% of all oral cancers. Five percent of all tumors occur in the head and neck, and approximately half of those occur specifically pertaining to the oral cavity. Tretinoin biofilm is a cost-effective alternative method used in the chemoprevention of oral cancer. All relevant search engines (google scholar, PubMed, etc.) searched for the literature pertaining to oral cancer, chemopreventive methods and the use of Tretinoin 'biofilm' in oral cancer prevention. The data was collected, and quality analysis of the collected data was done. The knowledge in the current point of time analysed and thus the consensus was established. Oral cancer has proved to be a major disease with major health issues leading to morbidity and mortality among the patients. The treatment for oral cancer is expensive and invasive and hence cannot be approached by everyone, leading to unfortunate consequences. This technique if successful, has the potential to be employed worldwide to treat oral cancer patients leading to the betterment of health and lifestyle.

Published: October 2020

Controversy exists as to the completion of endodontic procedures in a single visit or in multiple visits. Analyzing the frequency and distribution of single and multiple visit endodontics carried out based on demographic data can give us an insight towards the success of the treatment. This retrospective study aimed to analyse the frequency and distribution of maxillary teeth treated by single or multiple visit endodontics in an Indian population. Data for the study were collected retrospectively. Patient records of 86000 patients that reported to the institution between June 2019 and March 2020 were reviewed. Excel sheet tabulations were made involving age, gender, tooth number and number of visits. Descriptive statistics were applied using SPSS software. Association between each demographic data and the number of visits was analyzed by Chi-Square Test. A total of 4493 RCT procedures were done, of which 48.6% were single visit procedures and 51.4% were multi-visit procedures. The age group of 18-30 years (31.7%) and 31-40 years (29.3%) underwent the highest number of procedures, followed by 41-50 years (21%) and >50 years (18%). 51% 0f the procedures were done in males and 49% in females. Statistically, a significant association was observed between age, gender and tooth with a type of treatment (single or multiple visit endodontics), p<0.05. A statistically significant association between age, gender and tooth was observed with the type of treatment (single and multiple visit endodontics). Younger age group, males and maxillary central incisors showed the highest predilection to multi-visit endodontics. In general, more multi-visit procedures than single visit procedures were done in maxillary teeth.

Assignment of Morelet's crocodile Crocodylus moreletii individuals into size groups or classes based on ecological and morphological similarities has not yet been associated with species‐specific ontogeny related changes. Age or size of first reproductive behavior is not precisely known for C. moreletii, but differences in allometric patterns and relative cranial size between juveniles and adults might be used as an indicator of sexual maturity. In this study, a regression tree analysis was used to investigate the relationship between age and body size in 1266 crocodiles by using both simple and generalized linear models, with gender and origin (captivity or wild) as factors. Total length (TL), snout–vent length (SVL) and cranial length (CL) were used as predictor variables and the logarithm of body mass as the response variable. Four length intervals with well‐defined thresholds (514, 899 and 1497 mm of TL) were established using all three predictors (TL, SVL and CL). Relationship between SVL and TL was described, and a strong positive relationship (r2 = 0.98), unaffected by crocodile gender, was observed. The observed CL–TL and CL–SVL relationships were also positive but significantly different between males and females (p < 0.001) and length interval classes (p = 0.01). These results suggest that our estimated size thresholds seem to correspond to important ontogenetic changes in C. moreletii and that sexual maturity is closely related to size in this species, where sexual dimorphism in body length occurs, particularly in large individuals (size group IV).

The grey seal became locally extinct in the southern Baltic Sea, Danish Straits and Kattegat in the early 1900s after prolonged culling campaigns. Here, we combine national monitoring and anecdotal data from Denmark, Sweden, Germany and Poland to report on the grey seal's recolonisation of those areas and the initial reestablishment of breeding colonies. Grey seal occurrence has steadily increased since year 2003 as evidenced by the coordinated Baltic Sea moult censuses. At the first census in 2003, there were 146 grey seals along the southern Baltic coasts of Sweden and Denmark, ca 1% of the total Baltic Sea population count. Since 2015, this has increased to 2000–2600 grey seals, or ca 7% of the total population count. Since the local extinction, there have been sporadic breeding events in the 1940s on sea ice around Bornholm and in the 1980s and 1990s on haul‐outs in Kattegat. In 2003, the first two pups in the southern Baltic Sea were recorded at R⊘dsand, Denmark. This is to date the only site in the southern Baltic Sea with regular annual pupping since the recolonisation. Since 2000, there have also been sporadic breeding events in Danish Kattegat, southern Sweden, Poland and Germany. At R⊘dsand, there have been at least 3–10 pups recorded every year since initiation of monitoring in 2011, with an increasing tendency until 2017 with 10 pups counted, which subsequently decreased to 5–6 pups annually in 2018–2020. Compared to recolonising events in the Atlantic, the numbers of pups are low. This may be caused by differences in population dynamics, recolonisation distances, habitat and mortality and effects of rehabilitation programmes. It is likely that the breeding distribution will spread throughout the southern Baltic, Danish Straits and Kattegat if appropriate protection measures of seals and haul‐outs are installed.
A Conceptual Discussion of Rewriting as A Tool for the Translation(al) Turn
Authors: KIRAN Aysun
Published: October 2020

This article problematizes the strictly literary use of Andre Lefevere’s conceptualization of rewriting solely in the analysis of translated texts. It aims to discuss how the concept of rewriting can be deployed in the areas of research in social sciences and humanities outside literature and translation studies. To this end, the review first situates the concept of rewriting within the history of translation studies, and especially the emergence of the cultural turn. Subsequently, it delineates the defining aspects of Lefevere’s conceptualization of translation as a form of rewriting. While highlighting his contribution to a renewed understanding of the dynamics involved in the production of translated literature, this overview allows for elucidating the links between the notions of translation and adaptation through the frame of rewriting. In doing so, the article elaborates on the relevance of rewriting to the translation(al) turn by demonstrating its affinity with and divergence from the cultural turn. The Discussion and Conclusion section provides certain specific examples of how patronage can be applied to discuss the restraining or facilitating impact of a given political context on the production of film adaptations. Overall, this review proposes to consider the process of film production as one of rewriting in terms of the possible economic, ideological and status components involved therein. This conceptual discussion thus revisits the potential of rewriting as a methodological tool for a translation(al) turn in social sciences and humanities, which may develop avenues of collaboration between translation studies and other areas of interdisciplinary research.

The objectives of this research are to know the techniques used by the teacher in SLB Dharma Bhakti Dharma Pertiwi to teach English for speech impaired students, and to know how the techniques influence the students learning achievement. The research was done at SLB Dharma Bhakti Dharma Pertiwi in tenth and eleventh grade class in speech impaired class that consisted of 7 and 6 students. Data gathering was done by doing observation and interview to two teachers from ten and eleventh class. The results show that both teachers used mixed techniques in teaching English for speech impaired students. The teacher used some techniques like demonstration, repetition, and discussion. Demonstration can be done by showing pictures, using tools and touching the under part of the chin to teach pronunciation. Repetition can be done by repeating the words for many times to make the students remember. Discussion can be done by asking them questions to make the students active in the class. Some techniques were appropriate to improve students learning achievement but, there was a technique also that did not have a big impact in improving students learning achievement. By doing this research, it will help us to determine techniques in teaching speech impaired students. We know which technique that can help us to improve students learning achievement. It will help the students to get a better teaching learning process if we already know how to teach them.
