Authors: Burrows Tracy , Findlay Naomi , Killen Chloe , Dempsey Shane , Hunter Sharyn , Chiarelli Pauline , Snodgrass Suzanne
Published: September 2021

This paper describes the development of a peer review of teaching model for the Faculty of Health at the University of Newcastle, Australia. The process involved using the nominal group technique to engage Faculty academic staff to consider seven key decision points that informed the development of the peer review of teaching model. Use of the consensus based nominal group technique established collegial discussion and networking among participants, and has expanded the discussion within the Faculty about peer review of teaching. Although the academics come from a diverse multi-school and multi-program Faculty, there was high levels of consensus on the structure and process of the developed peer review of teaching model.
Editorial 8.3
Authors: Lefoe Geraldine
Published: September 2021

Welcome to the third and final issue of Volume 8 of the Journal of University Teaching and Learning (JUTLP) in 2011. As the year draws to a close we are seeing some striking changes to the higher education sector internationally. In England budget cuts have seen the closure of the twenty-four Higher Education Academy subject centres at the same time as the establishment of student fees. In Australia the cap has been lifted across the board on the number of students that can be enrolled in universities with the resultant projected increased student numbers. The focus in Australia is on social inclusion yet in England the concern for the introduction of fees is just the opposite, these will be the very students who may now be excluded.
The changes in both countries see new measures of accountability and more complex regulations put in place. Will this cause people to rethink the way we teach and the way students learn? For the Higher Education Academy in the UK, new directions see the hosting of a summit on learning and teaching with a focus on flexible learning, an indicator of new directions for many institutions. In Australia, we see a renewed opportunity to investigate such changes through the opening of the Office of Learning and Teaching (OLT) and its role of recognising the importance of learning and teaching through grants and awards schemes. We hope in 2012 we’ll hear more from our authors about the impact of these transformations, as well as those changes occurring in other countries around the world, on teaching practice in our universities.
Helping university students to ‘read’ scholarly journal articles: the benefits of a structured and collaborative approach
Authors: Fujimoto Yuka , Hagel Pauline , Turner Paul , Kattiyapornpong Uraiporn , Zutshi Ambika
Published: September 2021

Academics often treat students’ discipline-specific literacy as unproblematic. In doing so they may underestimate the difficulties for university students as they move between subjects of study that may involve different disciplines, language genres and academic practices. This paper describes an initiative aimed at supporting students in reading academic articles in preparation for completing an essay for an assessment task. This initiative involved a structured and collaborative two-week tutorial exercise that provided students with practice in using a framework to extract the main ideas from academic readings. Students were surveyed after this exercise, and their reflections of its value are described in this paper. The findings of this study will inform further stages of the project which aim to develop and investigate practical ways to develop student’s academic literacy across several business disciplines.
Undergraduate Student Acceptance of a Unit Design for Developing Independent Learning Abilities
Authors: Zutshi Samar , Mitchell Matthew , Weaver Debbi
Published: September 2021

This paper describes a method intended to advance students along the path to independent learning. The method is consistent with the principles of enquiry-based Learning. It involves restructuring student contact class time into a single three-hour block, and dedicating the majority of this time to working in small research project groups. Non-punitive, formative feedback is provided continuously on student work through the semester. In order to gain insight into the student experience of the design, a qualitative study using focus groups was conducted across two consecutive semesters. Reflection on the teaching experience in light of the student responses provides insight into aspects that have worked well, particularly the nature and channels of support provided to students. Despite the students’ unfamiliarity with the unit design, the contact structure and the group work has been popular and has been perceived as contributing to the students’ learning experience. The levels of support and feedback made possible through the unit design have also been very positively viewed. However, interesting questions are also raised. The first is regarding the balance between encouraging independent learning and the provision of structure and support by staff. The second is related to going beyond student perceptions and reliably measuring changes in independent learning abilities.
Evaluation of the Effectiveness of Online Resources in Developing Student Critical Thinking: Review of Literature and Case Study of a Critical Thinking Online Site
Authors: Carmichael Erst , Farrell Helen
Published: September 2021

A graduate's ability to be a critical thinker is expected by many employers; therefore development of students’ critical-thinking skills in higher education is important. There is also a perception that today’s students are technologically "savvy", and appreciate the inclusion of a technological approach to learning. However, the complexity of the concept of critical thinking and the assumptions about students’ technological skills are debatable issues that require clarification and evidence-based research in terms of teaching and learning. This paper reports on a case study of an online Blackboard site at the University of Western Sydney, where analysis of patterns of usage of the online site and qualitative analysis of student feedback provide evidence to support its effectiveness for encouraging students' critical thinking. There is potential to expand this into a more widely usable teaching and learning resource in the future, and for further research to explore the benefits for student learning.
Developing Animated Cartoons for Economic Teaching
Authors: Zhang Yu
Published: September 2021

Purpose – A picture is worth a thousand words. Multimedia teaching materials have been widely adopted by teachers in Physics, Biotechnology, Psychology, Religion, Analytical Science, and Economics nowadays. To assist with engaging students in their economic study, increase learning efficiency and understanding, solve misconception problems, encourage in class discussion, and increase final performance for students (especially for international students and RA students), some animations and cartoons are developed to explain basic economic concepts for both macroeconomic and microeconomic concepts, issues and events. Methodology – Two surveys were first conducted to collect first year and international students’ requirement and suggestions. Cartoons and animations were then designed and developed to solve the major misconception and misunderstanding problems facing first year students or international students in their economic studies. Qualitative interviews were conducted to collect feedbacks for the cartoons developed for this project from economic lecturers, tutors, students and other teachers and students without economic backgrounds. Learning efficiencies from animations and text materials are also compared by the length of learning time in this paper. Findings – Surveys in this study support the view that different students have different preferred learning methods. However, practice case studies are the preferred learning method for both first year university students and international students. The animated cartoons developed in this research received strong positive feedbacks from peer colleagues in Economics, teachers from other faculties, tutors in Economics, first year students, international students and RA students with dyslexic problems. Utilisation of these resources can improve learning efficiency, help students in their understanding and long-term memory of the subject, engage students in their studies, and increase interest in undertaking economic studies amongst all other students. Value – The results of this study could be used in any Economics subject, as well as for self-study by Economics students and others. As part of the Teaching and Learning Project, these materials are capable of being further used in mobile applications to assist in engaging students in their learning.
The effectiveness of oral presentation assessment in a Finance subject: An empirical examination
Authors: Bhati Shyam
Published: September 2021

The purpose of this paper is to study the effectiveness of oral presentation as an assessment tool in a Finance subject. Assessment data collected from a postgraduate Finance subject in an Australian university over a period of five years from 2005 to 2009 was analysed statistically to determine the relation between students’ performance in oral presentation and other forms of assessments. The sample consists of assessment records of 412 students and 98 group presentations. From the study of correlations between oral presentations and other assessments, it is concluded that students perform better in written assessments compared to oral assessment. The study of effect of gender on students’ performance leads to the conclusion that female students perform better than male students in all forms of assessments except oral presentations where male students perform better although difference between males and females in oral presentation is not very large. The study of students’ performance based on their nationality leads to the conclusion that domestic students perform better than international students in all forms of assessments. Based on the study of student’ performance in oral presentation, it is found that students did well in the development of content of presentations, quality of their analysis, group coordination and organisation of presentation. There is however a general tendency to treat group work as a sum of parts instead of treating the group work as a single task. This study is limited by the fact that effectiveness of oral presentation is studied in only one Finance subject. This study makes an original contribution to the literature as the effectiveness of oral assessment in Finance subject is being studied for the first time. The conclusions arrived in this paper have many implications for policies and practice of learning and teaching in Finance.
What constitutes effective feedback to postgraduate research students? The students’ perspective
Authors: East Martin , Bitchener John , Basturkmen Helen
Published: September 2021

Many Western universities are experiencing considerable growth in the numbers of postgraduate research students, both local and international. This increase and diversification bring with them challenges for how to make these students’ research studies successful. In particular, what students may wish to receive by way of supervisor-student relationships, and feedback within those relationships, may differ from what supervisors give, thereby creating potential tensions in the relationship and hindering effective learning. This article looks at what research students report they receive by way of feedback from supervisors, and what they say they find most effective. Evidence from questionnaires (n = 53) and interviews (n = 22) is used to draw some conclusions about how effective feedback is conceptualised from the students’ perspective. Analysis includes similarities and differences in response for students who speak English as a first or additional language.
Impact of a College Freshman Social and Emotional Learning Curriculum on Student Learning Outcomes: An Exploratory Study
Authors: Wang Ning , Wilhite Stephen , Wyatt Jeannette , Young Thomas , Bloemker Geraldine , Wilhite Emily
Published: September 2021

This study investigates the impact of implementing a social and emotional learning curriculum for college freshmen on student learning outcomes, including social and emotional competence and academic performance. Through the use of a quasi-experimental design, the growth in social and emotional competence of students who participated in the social and emotional learning seminars is compared with that of students who were enrolled in other freshman seminars. This comparison is complemented by a qualitative analysis of students’ self-reflections in relation to specific dimensions of social and emotional competence. The results of this study suggest that exposure to a social and emotional learning curriculum during the first semester at college may contribute to the development of social and emotional competence in students. Because of the potential relationship of social and emotional competence to academic success, this study also reports a comparison of the grade point averages (GPAs) of students from the social and emotional seminars with the GPAs of students from the other freshman seminars, while controlling for other predictors of academic success. The results indicate that students exposed to the social and emotional learning curriculum had higher grades than other students across the four semesters following the completion of the seminar.
Using capstones to develop research skills and graduate capabilities: A case study from physiology
Authors: Julien Brianna , Lexis Louise , Schuijers Johannes , Samiric Tom , McDonald Stuart
Published: September 2021

In 2011, the Department of Human Biosciences introduced two physiology capstone subjects as part of the Design for Learning Project at La Trobe University. Consistent with the project, the aims of these subjects were to provide an effective culmination point for the Bachelor of Health Science course and to offer students orientation to opportunities for further study, employment and career development. The aim of this paper is to provide an overview of the skills-related assessment tasks of the newly introduced capstone program and an evaluation of the capstone program based on student performance and feedback scores in conjunction with staff perceptions. The skills-related assessment tasks were designed to facilitate the development of research skills and graduate capabilities such as writing, speaking, creative problem-solving, inquiry/research and team work. Student performance determined by mean scores on the skills-based assessment tasks ranged from A to C. Final grades were significantly higher (p < 0.01) in 2011 when compared with final grades in 2010 and 2009. Students reported that the skills-based assessments contributed to their learning and skill development and satisfaction level was high. Staff noted a higher degree of student-centred learning, a vastly increased workload and a greater need for infrastructure services and support staff. Universities and departments should therefore consider staff and resource requirements when implementing curriculum that has a student-centred approach. In conclusion, the revised curriculum successfully promoted the development of research skills and graduate capabilities, thereby leading to work-readiness and/or entry to graduate studies in the Health and Biological Sciences.

Authors: HANDA MAYARA
Published: September 2021

O presente artigo busca apresentar a Síndrome de Down (SD) pelo olhar da psicomotricidade. A psicomotricidade é uma ciência importante, porém ainda pouco conhecida para estimular e intervir no desenvolvimento global da criança (no caso em específico a criança com SD). Analisando livros e artigos referentes ao tema, buscam-se compreender os benefícios da psicomotricidade para a hipotonia do SD, os benefícios provindos da estimulação psicomotora. Além destes, será utilizado o subtema que corrobora com o pretendido, as bases psicomotoras. Apesar de não ser recente, a psicomotricidade nas escolas ainda é pouco propagada e poucas são as pesquisas que a norteiam, sendo notável a falta de artigos que abordem os benefícios da psicomotricidade ligado especificamente à pessoa com SD na prática escolar, o que demonstra a importância deste.

A simple, specific, accurate, precise and stability-indicating RP-HPLC method was developed and validated for the simultaneous estimation of metformin HCl and canagliflozin in pharmaceutical formulation. The method was developed using the Altima C8 column (150 ×4.6 mm, 0.5 μm) with a mobile phase consisting of acetonitrile and 0.1 % orthophosphoric acid in water (62:38 %V/V) with a flow rate of 1 mL/min. Detection was carried out at 254 nm using a PDA detector. The retention time for metformin HCl and canagliflozin was found to be 2.282 and 3.339 min, respectively. The proposed method was validated for linearity, range, accuracy, precision, robustness, LOD and LOQ. Linearity was observed over a concentration range 15-225 μg/mL for metformin HCl (r2 =0.9995) and 5-40 μg/mL for canagliflozin (r2 =0.9988). The % RSD for intraday and interday precision was found to be 0.13 and 0.20 for metformin HCl and 0.18 and 0.20 for canagliflozin. The LOD and LOQ were found to be 0.16 μg/mL and 0.54 μg/mL for metformin HCl and LOD and LOQ were found to be 0.05 and 0.21 μg/mL for canagliflozin. Metformin HCl and canagliflozin were subjected to stress conditions of degradation including acidic, alkaline, oxidative, thermal and photolysis.

Dear Reader, COVID-19 pandemic has affected the whole world in a way that is unprecedented. The origin of the SARS-CoV-2 and the true scale of number of cases and deaths in every country is debatable. Nevertheless, it is clear that the spread of the virus is continuing worldwide with a devastating effect on the global economy. The control of the pandemic was essentially by implementing strict measures such as social distancing, use of personal protective equipment, personal hygiene and sanitation. There were numerous occasions since the beginning of the pandemic when governments across the world had rejoiced that their measures to control the spread of the infections had worked. However, non-compliance of safety measures and new strains of the virus led to the rise of the next wave of infections.

Authors: Морозов Алексей Сергеевич , Хильман Дмитрий Вадимович
Published: September 2021

Предметом исследования являются правовые нормы уголовно-исполнительного законодательства, регулирующие вещные права лиц, отбывающих уголовные наказания в виде лишения свободы. Целью исследования является установление тождества и различия в правовом регулировании вещных прав осужденных, отбывающих наказание в исправительных учреждениях и воспитательных колониях. Основными методами исследования являются анализ и синтез, а также сравнительно-правовой метод. В результате исследования установлено, что, несмотря на общий правовой статус осужденных, отбывающих наказание в виде лишения свободы, правовое регулирование одних и тех же вещных прав в различных ведомственных актах существенно различается, что влечет множество пробелов в праве и правовых коллизий. К числу основных выводов по результатам исследования можно отнести то, что в воспитательных колониях разрешен оборот боеприпасов, летательных средств, зажигалок, алкогольной продукции (за исключением алкогольных напитков) и некоторые другие. Результаты исследования могут быть реализованы в правоприменительной практике сотрудников, исполняющих уголовные наказания в виде лишения свободы, а также в процессе профессиональной подготовки сотрудников уголовно-исполнительной системы.

The subject of the research is the legal norms of the criminal Executive legislation regulating the real rights of persons serving criminal sentences in the form of imprisonment. The aim of the study is to establish the identity and differences in the legal regulation of the real rights of convicts serving sentences in correctional colonies and educational colonies. The main research methods are analysis and synthesis, as well as comparative legal method. The study found that despite the General legal status of convicts serving a sentence of imprisonment, the legal regulation of the same real rights in different departmental acts differs significantly, which entails many gaps in the law and legal conflicts. The main conclusions of the study include the fact that in the educational colonies allowed the circulation of ammunition, aircraft, lighters, alcoholic beverages (except alcoholic beverages) and some others. The results of the study can be implemented in the law enforcement practice of employees executing criminal penalties in the form of imprisonment, as well as in the process of training of employees of the penitentiary system.
QUANTITATIVE DETERMINATION OF SULPHATE REDUCING BACTERIA AND HYDROGEN SULPHIDE IN HUMAN SALIVA
Authors: Shaqra Qasem M. Abu , Groom Rania M. Al , Al-Gabbiesh Ahmad
Published: September 2021

"Objectives: Sulphate Reducing Bacteria (SRB) are part of the normal oral microbiota. They have been frequently detected in the oral cavity of individuals with and without oral manifestations. The aim of this investigation was to determine possible correlation between SRB count and their activity in saliva versus some oral health manifestations.
Methods: A total of 64 saliva samples were collected from healthy individuals, and patients with several oral manifestations. Detection and count of SRB were performed using documented methods, while sulphide ion concentration which is the metabolic end product of these bacteria was measured using a silver electrode connected to a millivolt meter.
Results: SRB were detected in 35.9% of saliva samples investigated. Statistical significance was observed between the detection of these bacteria and various oral conditions. However, count of SRB and the sulphide ion concentration in the tested samples did not have significant correlation with the oral conditions considered.
Conclusion: The mere detection of SRB in saliva is of significance in the diagnoses of oral conditions. Enumeration of these bacteria and quantification of their metabolic end product in the same samples were not of diagnostic value."

Conservative Management of Placenta Previa-Accreta in a First Trimester Missed Abortion.
Authors: Holliday Nicolette P.
Published: September 2021

The incidence of placenta accreta has been increasing along with the incidence of caesarean sections. There have only been a few case reports of placenta accreta diagnosed in the first trimester, and none in association with a missed abortion in a woman without risk factors. At a routine prenatal visit, a 33 year old G2P0101 at 12+6 weeks had an ultrasound demonstrating a fetus with a crown-rump length of 8+0 weeks, no fetal heart tones, a placenta previa, and a morbidly adherent placenta. The patient requested conservative management to help preserve her fertility. Imaging demonstrated an anterior placenta previa with extension of the placenta past the inner endometrium into the superficial myometrium wall and the myometrium adjacent to the superior surface of the bladder. Consultation with Maternal Fetal Medicine (MFM) at another institution similarly demonstrated a suspicion of vascular invasion of the uterine wall with no increased vascularity extending to the maternal bladder using color flow Doppler. The opinion from this second MFM team recommended expectant management with serial beta-hCG, ultrasounds, and serial physician visits as well. Her beta-hCG levels declined serially from 55262 to 4874 mIU/mL over eight weeks. Her serial ultrasounds showed involution of the placenta and reasborption of the fetus during that time. After nine weeks of conservative management, the patient underwent an uncomplicated suction dilation and curettage. Postoperatively, the patient did well and did not have any complications. A first trimester missed abortion with a placenta previa and accreta can be managed conservatively in the attempt to preserve future fertility.

Message Security Using a Combination of Hill Cipher and RSA Algorithms
Authors: Santoso Yogi Suryo
Published: September 2021

The process of exchanging digital messages is increasingly being used due to its easy and practical use. But the process of exchanging digital messages is vulnerable to being tapped by unauthorized people. Cryptography is the study of mathematical techniques related to aspects of information security, such as data confidentiality, data validity, data integrity, and data authentication. With cryptography, the process of exchanging messages between two people can be done securely. Thus, cryptographic techniques are used to overcome security issues when exchanging messages. The methods used in this study are hybrid hill cipher and RSA cryptography. In this study it was shown that hybrid hill cipher cryptography with a 3x3 matrix key and RSA with a 512 bit key can overcome security issues when exchanging data so that messages sent cannot be read by unauthorized people.

Published: September 2021

For the first time, cuprous oxide nanocubes (Cu2O NCBs) were successfully combined with chitosan nanoparticles (CS NPs) to generate Cu2O NCBs/CS NPs composites material with highly optical property and photocatalytic activity using a simple and eco-friendly synthetic approach at room temperature for 30 min. The synthesized Cu2O NCBs NPs/CS NPs were determined characterizations by Ultraviolet-visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), X – ray Diffraction (XRD),  Transmission Electron Microscope (TEM) and Energy-dispersive X-ray spectroscopy (EDX). Results show that the Cu2O NCBs/CS NPs composites have an average particle size of ~3-5 nm; in which, Cu2O has the form of nanocubes (Cu2O NCBs) with size ~3-4 nm and chitosan nanoparticles with spherical shape (CS NPs) with size ~4-5 nm. In addition, the percent (%) composition of elements present in Cu2O NCBs/CS NPs composites material have been obtained respective: Cu (23.99%), O (38.18%), and C (33.61%). Moreover, Cu2O NCBs/CS NPs composites material was also investigated for photocatalytic activity applied in p-nitrophenol degradation. The obtained results showed that the catalytic capability of Cu2O NCBs/CS NPs for p-nitrophenol reduction reached the highest efficiency >55% in the treatment time of 25 min, and this efficiency was higher than that result of using ZnO@chitosan nanoparticles (ZnO@CS NPs) catalyst under the same conditions for comparison.
Selectividad étnica en el discurso migratorio de Vox: entre el pragmatismo y el esencialismo
Authors: Cheddadi El Haddad Zakariae , León Ranero José Manuel
Published: September 2021

La irrupción política del partido de derecha radical Vox en el sistema político español ha abierto nuevos espacios para la investigación académica, y uno de los más pertinentes es el estudio de su discurso migratorio. Partiendo de la hipótesis central de la existencia de un discurso diferenciado sobre la inmigración en función del origen étnico, el trabajo tiene como objetivo determinar su relevancia, orientación y argumentación. Para la realización de esta investigación, se ha optado por una metodología cualitativa a través de la aplicación del análisis de contenido y del método de la cadena causal a una muestra de fuentes documentales y audiovisuales. Los resultados de este estudio revelan que Vox utiliza un discurso de diferenciación étnica bimodal de naturaleza predominantemente identitaria, y que el origen étnico determina la interacción entre el mecanismo segregativo étnico y otros tipos de diferenciación presentes en la expresión pública del partido de derecha radical analizado.
Risk Perception and Coping Strategies among Direct Support Professionals in the Age of COVID-19.
Authors: LoPorto Johanna , Spina Kelly E
Published: September 2021

The spread of novel coronavirus (COVID-19) across the globe and its associated morbidity and mortality has impacted and challenged society in many ways, which resulted in adapting to a new way of life. One underrecognized and unaddressed area is the mental health of essential employees providing services to people with intellectual and developmental disabilities (IDD). Direct support professionals (DSPs) serve an important function in the daily supervision and care of clients with IDD. It is not clear, however, how these essential workers perceived their own risk of contracting COVID-19 while working during this pandemic. Our research presents results of a national survey of 478 DSPs that focused on perceptions of risk and ways of coping with COVID-19. Using an online survey, we examined DSPs’ perception of risk and on the emotional and problem-solving strategies they used to cope with the global crisis. We found that DSPs engaged in higher problem-focused strategies rather than emotion-focused strategies in coping with the virus. As such, we show that it is critical for IDD provider organizations to assess DSPs’ needs to provide coping supports during the age of COVID.
A FORGOTTEN HERO: JAN MORAWIŃSKI

Notes of a Curator at the National Museum
published in 1970 in the second volume of the book
Struggle for Cultural Goods is the only generally available
testimony to saving the Wilanów historic monuments by
Jan Morawiński, a forgotten hero from the times of WW II.
Additionally priceless because of Morawiński documenting
the looting of 137 paintings belonging to the pre-WW II
Branicki collection at Wilanów. The above-mentioned Notes
were published by the Państwowy Instytut Wydawniczy after
the manuscript kept in the private archive of the author’s
daughter Agnieszka Morawińska. The notes, however,
resemble pieces of paper torn from a notebook in which
an earlier chapter is missing. The missing chapter does exist,
yet for unknown reasons was omitted in the two-volume
Struggle for Cultural Goods. Warsaw 1939–1945 edited by
Prof. Stanisław Lorentz.
The present paper is based on Morawiński’s hand-written
testimony, supported by archival sources and recollections
of his colleagues from the National Museum in Warsaw
(MNW). From August 1939 to August 1944, Jan Morawiński,
together with others, was involved in saving precious museum
exhibits in the Museum building, but also throughout
Warsaw. He was involved in packing the historic monuments
into crates which were to help them survive the toughest
times, and he helped to put out fires at the Museum, risking
his own life. Moreover, he rescued the Royal Castle collections
during the hardest bombing of Warsaw, transporting
them to the storages in Warsaw’s Jerozolimskie Avenue. For
his dedication he was awarded the Virtuti Militari Cross of
the 5th class by Gen. Juliusz Rómmel.
After Warsaw’s surrender, he was assigned Head of
MNW’s storerooms and inventories: when Director Lorentz
was absent, he acted as his deputy. In the first period of
the Nazi occupation he courageously faced German officials.
Furthermore, he headed the clandestine action of inventorying
and documenting German destructions and plundering.
The knowledge amassed in this way was extremely helpful
in the restitution of the looted historic monuments, not only
museum ones. He also contributed to documenting the destruction
of the Warsaw Castle. Imprisoned by the Nazis, he
went through Gestapo’s hands at Daniłowiczowska Street
in Warsaw. Later on, he became manager of the Museum
of Old Warsaw in the Old Town, at the same time acting
as a guardian of the Wilanów collection. Following the defeat
of the Warsaw Uprising, he participated in the so-called
Pruszków Action in whose course he was badly injured.

Considering the planned amendments under the Financial Market Integrity Strengthening Act, the author first analyzes to what degree IFRS and reporting standards under the German Commercial Code grant managers discretion when preparing the annual and consolidated financial statements of a company. She then examines how to exercise such discretion in accordance with § 93 subsection 1 of the German Stock Corporation Act and to what extent accounting decisions are protected by the business judgment rule.

To embark on an anti-vectorial fight against mechanical vectors of animal trypanosomosis, investigations were undertaken in order to determine the abundance, species diversity and daily activity of tabanids in a cattle ranch in Gabon. The nzi and vavoua traps were used to catch tabanids in three divisions of this ranch. In this study, 616 tabanids were captured: 349 (56.66%) in Division 1, 226 (36.69%) in Division 2 and 41 (6.66%) in Division 3. In the first Division, T. taeniola was the most abundant species with an Apparent Density (ADT) of 2.2, followed by H. pluvialis (ADT = 1.05). In the second Division, H. pluvialis was most abundant with ADT of 1.6, followed by T. taeniola (ADT = 0.38). In the last Division, the most abundant species was H. pluvialis (ADT = 0.15). Comparing the relative abundance of catches with sites (Divisions), we realized that there was no statistically significant difference in catches with trapping sites. It was noticed that Division 3 recorded the highest diversity index values. We realized that the nzi trap recorded higher tabanid catches than the vavoua trap. The diurnal activity rhythm of the most frequent species encountered slightly differed with prospection sites.
Endogenous Enzymatic Antioxidant Defense and Pathologies
Authors: Eddaikra Atika , Eddaikra Naouel
Published: September 2021

Oxidative stress is an important component of various diseases. It manifests as an imbalance caused by an excessive production of reactive oxygen species (ROS) which are associated with a deficit of antioxidant activity. This deficit can be the consequence of genetic factors, environmental ones, metabolic imbalance, toxicity or direct attacks by the accumulation of free radicals. These can induce metabolic dysfunction affecting biological macromolecules in their structures or activities. From a physiological perspective, the neutralization of free radicals is ensured by enzymatic, antioxidant and non-enzymatic defense systems. In the present chapter, we will focus on the endogenous enzymatic antioxidant defense system such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPxs), thioredoxin (Trx) and paraxonase which play an important role in homeostatic redox balance. Also, we will review this set of antioxidants enzymes within different pathological states such as diabetes, cancer, autoimmune diseases, cardiovascular, Alzheimer’s, Parkinson’s or parasitic diseases such as Leishmaniasis and Malaria.
Biosynthesis and Regulation of Antioxidant Flavonolignans in Milk Thistle
Authors: Drouet Samantha , Hano Christophe
Published: September 2021

Mature fruits (achenes) of milk thistle (Silybum marianum (L.) Gaertner, Asteraceae) accumulate high amounts of silymarin, a complex mixture of bioactive antioxidant flavonolignans deriving from taxifolin. Their biological activities in relation with human health promotion and disease prevention have been well described. The conditions of their biosynthesis in planta, however, have long been elusive and thus tend to be a limiting factor for their future applications. Significant advances in understanding their biosynthesis and regulation have been made over the last decade and are outlined in the current chapter.
Non-Keplerian Orbits in Dark Matter
Authors: D. Morley Peter
Published: September 2021

This paper is concerned with the mathematical description of orbits that do not have a constant central gravitating mass. Instead, the attracting mass is a diffuse condensate, a situation which classical orbital dynamics has never encountered before. The famous Coma Cluster of Galaxies is embedded in Dark Matter. Condensed Neutrino Objects (CNO), which are stable assemblages of neutrinos and anti-neutrinos, are candidates for the Dark Matter. A CNO solution has been attained previously for the Coma Cluster, which allows mathematical modeling of galaxy orbital mechanics within Dark Matter, first reported here. For non-zero eccentricity galaxy orbits, each point along the trajectory sees a different gravitating central mass, akin to satellite orbits inside Earth. Mathematically, the galaxy orbits are non-Keplerian, spirographs.

Antiphospholipid syndrome which is also known as APS is an autoimmune disease which represents an acquired form of thrombophilia. The etiology of APS remains unknown. This disorder occurs when the immune system mistakenly attacks some of the normal human proteins and manifests itself as recurrent arterial or venous thrombosis and it could emerge after abortions or in recurrent pregnancy loss. In APS, the body produces the wrong antibodies against phospholipid-binding proteins, that is present in the blood and plays an important role in coagulation. Antibodies are specific proteins that usually target and neutralize the body’s invaders, such as viruses and bacteria. When antibodies attack phospholipid-binding proteins, blood clots abnormally. Specifically, it could cause blood clots in veins or arteries leading to stroke and various pregnancy complications such as: endometrial death, miscarriage, preeclampsia, intrauterine growth restriction and prematurity. APS is divided into primary and secondary, which is associated with autoimmune diseases and more often with systemic lupus erythematosus (SLE), while antibodies against cardiolipin are detected in many other conditions (infections, malignancies, drugs, etc.). The symptoms of APS, in addition to arterial and/or venous thrombosis and pregnancy complications, are multisystemic and the differential diagnosis of the primary APS from the secondary, in the context of SLE, is of particular clinical interest and is subject of this literature review.
Regional Anesthesia in the Prevention of Chronic Postoperative Pain
Authors: O. Lezcano Velazquez Brenda , A. Castorena Arellano Guillermo
Published: September 2021

Chronic postsurgical pain (CPSP) develops after a surgical procedure but increases its intensity and persists beyond the healing process without another cause to explain it. The incidence ranges from 5–85%, according to the type of surgery. Patients who develop CPSP may have a protracted ambulation, cardiac and pulmonary complications and increased morbidity and mortality. Several risk factors have been found related to the development of CPSP: female gender, young age, genetic predisposition, and psychosocial problems, hence prevention, early identification and treatment of these factors is essential. Several guidelines recommend the use of multimodal analgesia to treat postoperative pain, and the perioperative management seems to have a preventive role in the development of CPSP. Regional anesthesia (RA) either neuraxial or peripheral nerve blocks, by modulating signaling created by a surgical incision, play a key role in the prevention of CPSP. Local anesthetics have anti-inflammatory properties which decrease sensitization, reduce ectopic firing of neurons, cytokines expression and decrease neutrophil priming. RA reduces pain signals to the spinal cord and supraspinal and cortical nociceptive centers. RA along with other pharmacologic interventions can improve the CPSP as well as the physical and social functionality.
