Analysis of the Results of Using the Means of Organisation of Distance Learning when Training the Future Primary School Teachers under the Conditions of Quarantine
Authors: Sukhovirskyi Oleh V. , Liakhnovych Nina O.
Published: June 2021

The study analyses the results of using software and hardware during distance learning. The basis for the study was the Khmelnytskyi Humanitarian-Pedagogical Academy and the Municipal Institution of Higher Education “Mykhailo Hrushevskyi Barskyi HumanitarianPedagogical College”. A survey of students who studied computer science in the 1st and 2nd year of the specialty “Primary Education” was conducted. This allowed studying the attitude of the future primary school teachers towards different means of distance learning, determining the conditions for organising distance learning for students of both institutions, comparing the results of teaching computer science for the future primary school teachers by distance and conventional forms. It was found that most students are positive about the use of the platforms offered by the institution and consider their opportunities sufficient for their learning. Adaptation to the new platforms and tools took several weeks. The most popular among the tools were Google Classroom, blog, cloud documents, video tutorials on YouTube, online tests, and more. Quite a large number of students underestimate the effectiveness of video conferencing and prefer other types of electronic materials. However, when explaining new material, sounding presentations increases the level of knowledge acquisition. The main problems that students face during distance learning are the lack of access to computer devices and the Internet, as well as a considerable number of tasks in various disciplines, which causes overload and deterioration of both students’ well-being and the quality of their education. The study of students’ grades in the discipline “Computer Science” in 2019 and 2020 made it possible to compare the results at the beginning of quarantine and at the end of the semester. This approach allows determining the effectiveness of the use of distance learning. The results indicate that during the quarantine there was no considerable deterioration in student grades. Statistical analysis confirmed the identity of the results of semester control in groups that studied in the conventional and distance form

Authors: Fastivets Anna V.
Published: June 2021

Under conditions of considerable degradation of health of the nation, the problems of professional training of future physical therapy specialists at higher educational institutions become more topical. Therefore, the problem of developing the special educational conditions of training of future physical therapy specialists for the use of healthpreserving technologies does not lose its relevance. The purpose of the study is to analyse the key educational conditions of training of future physical therapy specialists for the use of health-preserving technologies. To meet the specified purpose the author used a complex of research methods, in particular, theoretical methods: analysis and synthesis of scientific and methodical literature, methodological documents; generalisation of the results of scientific research; synthesis of scientific theories, approaches and conceptions. Considering the current state of training of future physical therapists for the use of health technologies, it is established that the development of appropriate pedagogical conditions is promising. Among the latter, the author identified the following: stimulating interest in the study of health technologies by conducting tours and organising communication with well-known instructors during the educational process; development of the cognitive basis for the use of health technologies during interactive lectures, work in microgroups, solving situational problems, building schemes, individual, and group health programmes; practical use of available theoretical knowledge in the process of classroom (role-playing games, mutual learning with further analysis of video materials) and quasiprofessional (introduction of health technologies in educational practice) activities; introduction of an appropriate system for assessing the quality of training of future physical therapists for the use of health technologies in the educational process

Authors: Avunduk Yesim
Published: June 2021

This study aimed to determine the relationship between leisure satisfaction and social media addiction of university students. The study group of the research was formed by the voluntary participation of 193 students (133 male and 60 female), studying at the School of Physical Education and Sports of Istanbul Gelişim University. In addition to the personal information form, the “Leisure Satisfaction Scale (LSS)” developed by Beard and Raghep (1980) and adapted into Turkish by Gökçe and Orhan (2011), and the “Social Media Addiction Scale (SMAS)” developed by Bakır Ayğar and Uzun (2018) were used as data collection tools. After the data showed normal distribution in the Kolmogrov-Smirnov normality test, t-test, ANOVA and Pearson Correlation test were used in the analysis. The level of significance in the study was set at 0.05. In the research findings; gender and age groups of individuals affect their leisure time satisfaction levels; It has also been found that age groups affect social media addiction. As a result, it was determined that leisure satisfaction levels and social media addiction changed according to various variables of university students, and a negative significant relationship was found between leisure satisfaction and social media addiction.

Published: June 2021

The hydroxyapatite layer was deposited on the commercial magnesium alloy of AZ91 by electrophoretic deposition route, and the corrosion behavior of applied layers was studied by polarization and electrochemical impedance spectroscopy at the Simulated Body Fluid (SBF) solution. The best corrosion resistance improvement was obtained for the sample synthesized at 40 V within 4 minutes. Also, the morphology of coated samples was studied by atomic force microscopy (AFM) and the surface parameters were measured. It could be concluded that the calculated values for surface parameters including surface roughness, maximum peak height, maximum pit depth, and maximum peak have a meaningful relationship with corrosion resistance.
Airway Pressure Release Ventilation setting disagreements. A survey of clinicians
Authors: Randhawa Sandeep Randhawa , Sato Ryota , Daoud Ehab
Published: June 2021

Background: Airway pressure release ventilation has been available to clinicians for the last four decades. Unfortunately, its clinical value continues to be debatable. One of the many reasons responsible is the lack of consistency between its settings in clinical practice and research. We hypothesized that clinicians disagree on specific methods when establishing these parameters. Materials and Methods: A questionnaire-based survey was developed and sent to clinicians (critical care attending physician, critical care fellows in training and respiratory therapists) in about one hundred different academic hospitals with critical care training program. The survey consisted of ten questions including each of the four major APRV settings: T-High, T-Low, P-High, and P-Low. The survey was anonymous. Main results: Amongst the 187 respondents, there were significant disagreements between different categories of clinicians regarding methodology for establishing initial settings of APRV. However, when the responses were analyzed after sub-grouping based on categories of clinicians (Critical care attending physician vs critical care fellows vs respiratory therapists), no significant differences could be found. Conclusions: There is no agreement between different categories of clinicians when it comes to the methodology for establishing initial APRV settings. Our study highlights the need for larger clinical trials comparing different approaches to the same which could then be used for establishing scientific guidelines based on best evidence. Keywords: APRV, survey, T-High, T-Low, P-High, P-Low
Art as Expression of Emotion Explored in Anna Karenina
Authors: Oatley Keith , Jenkins Jennifer M.
Published: June 2021

Robin Collingwood proposed that works of art are expressions of artists’ emotions and that those who engage with them can become better able to understand emotions of their own. We apply this approach to Leo Tolstoy's Anna Karenina, thought by many to be the world's best novel. In this book, Tolstoy wrote of situations in ways that can evoke surprise. He showed its protagonists presenting themselves as if on a stage, but they are ambivalent: they ricochet between emotional states such as flaunting and attempts to avoid shame with the result that readers can experience what they would feel in the circumstances portrayed. This enablement of readers’ emotions may be as important as the depiction of character, which is often said to be the central feature of literary novels.
Methodological problems of interdisciplinary peace research
Authors:   Vasyl Stefanyk Precarpathian National University, Genyk Mykola
Published: June 2021

The increase in international tensions and the threat of global selfdestruction has determined the appearance of new interdisciplinary sciences aimed to investigate ways of contradictions resolving and raising the peace process’s effectiveness. Since the Second World War, issues of peace have become the object of study for several disciplines: polemology, eirenology, conflict resolution, and peace studies. They coexisted and rivalled in questions of methods and ways of cognition and achievement of peace. From 1960 to 1980, peace studies had been taking the first place. It had broadened and deepened the object and methods of peace research and been transformed into a separate interdisciplinary scientific field for studying and analyzing the preconditions for forging a lasting peace. Peace studies has combined conflict studies, development studies, philosophical-ethical reflections, historical context, and the international relations theory. Within peace research, two main schools have coalesced. The American traditional school (J. Burton) went in for peace keeping through predominantly analyzing international relations, arms control, disarmament, balance of power, and methods to establish peace „from the top”. The Scandinavian critical school (J. Galtung, B. V. A. Rolling, K. Boulding), based on updated social doctrine of the catholic church (the encyclicals of Pope John XXIII and Pope Paul VI), studied the underlying basis of conflict, having developed the theory of positive peace as a state of absence of not only direct but also of structural violence. Since the beginning of the 21st century, over 300 academic institutions and universities have been engaged in peace studies. Current peace research focuses on problems of global climate change, terrorism, sustainable development, failed states, and violation of human rights. At the same time, unsteady terminology is a significant problem of peace studies. R. Seidelman spoke about peace studies as a discipline in its infant stage. Evidently, a hybrid type of warfare, novel compound risks and threats to international security will promote the appearance of new directions of peace research. Key words: war, conflict, peace studies, peace research, peace process, conflict resolution, polemology.

Computing Competency for Civil Engineering Graduates: Recent Updates and Developments in Saudi Arabia and the US
Authors: Ahmed Danish , Nayeemuddin Mohammed , Ayadat Tahar , Asiz Andi
Published: June 2021

This paper discusses recent updates and developments of computing-based courses in the civil engineering discipline. Competency in computing is one of the most important capabilities for university graduates to obtain given the rapid development of computer technology in professional work. Civil engineering is no exception. In fact, many contemporary civil engineering projects require a high degree of computing skills, ranging from performing basic office work to programming for decision support system application in controlling flood water gates to executing construction automation via digital printing technology. However, the curriculum content for computing in civil engineering has been developmentally stagnant in the past several decades. This could be partly due to learning outcomes for civil engineering graduates, which do not explicitly mention a certain degree of achievement with respect to computing skills. Several computing-based courses offered in various civil engineering programs across Saudi Arabia and the US were examined, and their contents were compared to recent survey results administered by the American Society of Civil Engineering Technical Committee on Computing and Information Technology. The discussion is extended by examining technical courses offered in the Civil Engineering Program in Prince Mohammad Bin Fahd University with respect to computing skills. The outcomes of this study are expected to give input and suggestions for future upgrades of computing-based courses offered within the civil engineering curriculum.

Published: June 2021

Las personas con discapacidad intelectual y del desarrollo, particularmente las mujeres, son especialmente vulnerables a las situaciones de abuso sexual. El objetivo principal de esta revisión es examinar los estudios empíricos sobre la efectividad de programas de prevención del abuso sexual en esta población. Una búsqueda sistemática en PsycINFO, Web of Science y Psicodoc, identificó diez estudios publicados sobre el tema. Los resultados obtenidos muestran que la mayoría de los programas de prevención están basados en la adquisición de habilidades conductuales y que hay otros centrados en la educación sexual. Aunque existen datos que demuestran la efectividad, sobre todo, de los programas de habilidades, la mayoría de los estudios no ofrecen resultados robustos con los que juzgar la efectividad de estas intervenciones. Las conclusiones de la revisión se centran en la necesidad de aumentar la investigación sobre la población con discapacidad intelectual y del desarrollo, especialmente en mujeres y en el ámbito del abuso sexual.

Glass ionomer cements (GICs) are currently the first-choice materials in minimally invasive dentistry and are widely used in paediatric dentistry. The objective of this study was to evaluate the influence of viscosity and mixing on porosity and the relationship between the porosity and microhardness of GICs. Nine GICs were used: EQUIA® Forte Fil, Ionostar®Plus, 3MTMKetacTM Universal AplicapTM, Riva Light Cure HV®, Riva Silver®, Riva Protect®, VitremerTM, VitrebondTM Plus and Activa BioActive RestorativeTM. Samples were prepared from each material and images were obtained by scanning electron microscopy (SEM). Using software, the number and diameter of pores, area, and percentage of area they occupied were measured. After SEM analysis, the samples were used to make surface microhardness (SMH) measurements. Ionostar® Plus, EQUIA® Forte Fil and Riva Light Cure HV® had the highest number of pores. Riva Protect® had the largest pores and the highest percentage of pore-occupied area, while Activa BioActive RestorativeTM and VitrebondTM Plus had a smaller pore size and a smaller percentage by area. Riva Silver® and EQUIA® Forte Fil showed the highest microhardness values and VitrebondTM Plus and VitremerTM the lowest. In conclusion, when the cement viscosity is low, the type of mixture determines the degree of porosity, but has less influence when viscosity is high. There was no correlation between microhardness and the porosity of GICs.
Finding Our Way Home
Authors: Kirkland Sean D. ,   Philosophy Documentation Center
Published: June 2021

Situating the Philebus within the greater context of Plato’s late-period reconsideration of his own “theory of Ideas,” this essay offers a coordinated interpretation of two of the dialogue’s central passages—the discussion of the God-Given Method and that of the Fourfold Ontology. These passages prove to be interested not in Ideas apart from their material instantiations, as often seemed the case in the middle period dialogues, but in Ideas as they work on and even in materiality as such, producing an intelligible and even beautiful order in the sensible world. This entails, the essay suggests, something like a shift in the direction of Plato’s philosophical gaze and interest toward material being, and thereby a sort of return home to the embodied human condition.
Dignitas personae, HEK 293, and the COVID Vaccines
Authors: Moschella Melissa ,   The National Catholic Bioethics Center
Published: June 2021

Using cell lines like HEK 293 or their products—like many of the COVID-19 vaccines—involves no cooperation with evil strictly speaking, but it does involve appropriation of the benefits of past evil. Applying M. Cathleen Kaveny’s framework for assessing the permissibility of appropriating the benefits of evil, the duty to avoid using cell lines like HEK 293 or their products is weak and defeasible. Proper interpretation of Dignitas personae requires recognizing the crucial moral differences between the use of these cell lines—which does not perpetuate the injustice of abortion, imply approval of abortion, or involve significant risks of corrupting moral character or provoking scandal—and the direct use of fetal tissue or human embryos in research.
Reading Samaritanus bonus in Light of Magisterial Teaching and Recent Papal Writings
Authors: Coleman Gerald D. ,   The National Catholic Bioethics Center
Published: June 2021

On July 14, 2020, the Congregation for the Doctrine of the Faith (CDF) issued Samaritanus bonus (The Good Samaritan), beckoning the human family to take the Good Samaritan as the ideal in the care of all persons in critical and terminal phases of their lives. The import of this letter is understood best as seen through three prisms: (1) Fratelli tutti, the encyclical of Pope Francis signed at Assisi on October 3, 2020; (2) the Declaration on Euthanasia issued by the CDF in 1980; and (3) “the remarkable progressive development of biomedical technologies [which] has exponentially enlarged the clinical proficiency of diagnostic medicine in patient care and treatment [which] call for growth in moral discernment to avoid an unbalanced and dehumanizing use of the technologies especially in the critical or terminal stages of human life” (CDF, Declaration on Euthanasia, intro)

This system, termed the Risk Exploration System (“RES”), is a lean, flexible framework with three main activities: exploration of risk, communication of risk, and organizational support. The author demonstrates how the different stakeholders could engage in each of these three activities.
Genetic Genealogy and its Use in Criminal Investigations: Are We Heading Towards a Universal Genetic Database?
Authors: Plemel Emily
Published: June 2021

In April 2018, Joseph DeAngelo also known as The Golden State Killer was caught and convicted. This was made possible by 40-year-old DNA evidence, genetic genealogy, and current information systems technology. This paper will discuss the history of genetic information such as DNA testing used in forensics, and consider information technologies effect on the future of criminal investigations. The main focus is genetic databases and their management. How will the management of these databases affect the public and law enforcement? Could a universal genetic database create solutions to the current criminal database systems, often critiqued for being discriminatory? How can we use genetic genealogy more efficiently to solve crimes?  The sources used for this exploration include companies such as GEDmatch, 23andME, and Ancestry; key players of the field such as Barbara Rae Venter and CeCe Moore; newspaper articles, statistics, and academic journals.
Saviours or Burdens? The Effects of Streaming Services on the Music Industry
Authors: Nicholson Robyn
Published: June 2021

This research essay provides an overview of streaming services and their effects on the music industry, and the tensions they have created between various stakeholders. The problem of the “end” of the music industry is addressed through discussing the transition of music from analog to digital, the history of music piracy, and the value of music as a commodity. Technological, institutional, and cultural tensions are highlighted, and revenue distribution is described and analyzed, as is the interplay of algorithmic and human curation of playlists. Legal issues are also raised involving the privacy of users and intellectual property rights of artists. A middle ground is sought, and possible solutions are proposed to reconcile these tensions, with the future of the music industry in mind.
Balancing Print and Electronic Collections in Public Libraries: Perspectives for a Changing World
Authors: Larose Cassandra
Published: June 2021

Public libraries are of vital importance to their communities, providing access to information, shelter, services, and serving as an anchor for economic and social growth. As public libraries adapt to an increasingly digital world, they must address the balance of print and electronic materials to ensure that users have access to what they want and need. While public libraries’ print collections are decreasing at a slower rate than those of their academic counterparts, they are also facing increasing pressure to offer materials electronically. Public libraries must address challenges in tracking usage statistics as well as their users’ attitudes towards ebooks and print materials. Resource issues must be addressed, including costs and staffing. An increased desire for flexible space within library branches may also be a consideration impacting print collections. In addressing issues of accessibility, both print and electronic materials may create barriers in some instances while increasing access in others. The closure of many public library spaces during the COVID-19 pandemic in 2020 has introduced new issues, including limitations to access of print materials, new ease of access to online materials, and additional resource limitations as libraries work with limited budgets and staff. While the shift to online services during the COVID-19 pandemic has likely sped up the transition to increasing availability of online resources in public libraries, an appetite for print materials remains.
Experimental Full Scale Study on Yacht Sails and Rig under Unsteady Sailing Conditions and Comparison to Fluid Structure Interaction Unsteady Models
Authors: Augier Benoît , Bot Patrick , Hauville Frederic
Published: June 2021

This work presents an experimental study on the aeroelastic wind/sails/rig interaction at full scale in real navigation conditions with the aim to give an experimental validation of unsteady Fluid Structure Interaction (FSI) models applied to yacht sails. An onboard instrumentation system has been developed on a J80 yacht to measure simultaneously and dynamically the navigation parameters, yacht motion, and sails flying shape and loads in the standing and running rigging. The first results recorded while sailing upwind in head waves are shown. Variations of the measured parameters are characterized and related to the yacht motion (trim mainly). Coherence between the different parameters is examined. In the system’s response to the dynamic forcing (pitching motion), we try to distinguish between the aerodynamic effect of varying apparent wind induced by the motion and the structural effect of varying stresses and strains due to the motion and inertia. The simulation results from the FSI model compare very well with the experimental data for steady sailing conditions. For the unsteady conditions obtained in head waves, the first results show a good agreement between measurements and simulation.

Published: June 2021

O morango (Fragaria × ananassa Duch) é uma fruta explorada em diversos produtos processados, tal como geleias, assim promovendo a acessibilidade ao consumo dessa fruta.  Neste trabalho objetivou-se avaliar a interferência de diferentes genótipos de morango no processamento e em características físico-químicas e sensoriais de geleias. Para isto, foram utilizadas as seleções CREA FRF LAM01, CREA FRF LAM18, CREA FRF PA109 e CREA FRF FC104 sob manejo orgânico. As geleias foram caracterizadas pela análise sensorial e determinação de acidez titulável, sólidos solúveis, ratio, pH, teor de compostos fenólicos totais e antocianinas totais. Sensorialmente não foram demonstradas diferenças significativas (p < 0,05) entre as geleias produzidas. Com relação a caracterização físico-química das amostras houve variação (p < 0,05)  entre a acidez titulável e teor de sólidos solúveis em algumas amostras, porém o cálculo do ratio mostra apenas a amostra CREA FRF PA 109 destacando-se das demais, com um ratio de 179,40 ± 0,44 e as demais em uma faixa de 147,75 a 159,78. O teor de compostos fenólicos totais e antocianinas totais se mostrou superior (p < 0,05) na amostra  CREA FRF LAM18, sendo 49,39 ± 3,88 e 2,38 ± 0,18, respectivamente. Com este estudo observa-se a aceitação não se alterando de acordo com o genótipo utilizado na produção de geleia, porém, houve variação nas características físico-químicas, podendo assim ser um indicativo para o produtor selecionar o melhor genótipo para o seu produto.

In this paper, we define new families of Generalized Fibonacci polynomials and Generalized Lucas polynomials and develop some elegant properties of these families. We also find the relationships between the family of the generalized k-Fibonacci polynomials and the known generalized Fibonacci polynomials. Furthermore, we find new generalizations of these families and the polynomials in matrix representation. Then we establish Cassini’s Identities for the families and their polynomials. Finally, we suggest avenues for further research.

An r-dynamic coloring of a graph G is a proper coloring of G such that every vertex in V(G) has neighbors in at least $\min\{d(v),r\}$ different color classes. The r-dynamic chromatic number of graph G denoted as $\chi_r (G)$, is the least k such that G has a coloring. In this paper we obtain the r-dynamic chromatic number of the central graph, middle graph, total graph, line graph, para-line graph and sub-division graph of the comb graph $P_n\odot K_1$ denoted by $C(P_n\odot K_1), M(P_n\odot K_1), T(P_n\odot K_1), L(P_n\odot K_1), P(P_n\odot K_1)$ and $S(P_n\odot K_1)$ respectively by finding the upper bound and lower bound for the r-dynamic chromatic number of the Comb graph.
Bi-unitary multiperfect numbers, V
Authors:   Faculty of Information Technology and Communication Sciences, Tampere University, Haukkanen Pentti , Sitaramaiah Varanasi
Published: June 2021

A divisor $d$ of a positive integer $n$ is called a unitary divisor if $\gcd(d, n/d)=1;$ and $d$ is called a bi-unitary divisor of $n$ if the greatest common unitary divisor of $d$ and $n/d$ is unity. The concept of a bi-unitary divisor is due to D. Surynarayana (1972). Let $\sig^{**}(n)$ denote the sum of the bi-unitary divisors of $n$. A positive integer $n$ is called a bi-unitary multiperfect number if $\sig^{**}(n)=kn$ for some $k\geq 3$. For $k=3$ we obtain the bi-unitary triperfect numbers. Peter Hagis (1987) proved that there are no odd bi-unitary multiperfect numbers. The present paper is part V in a series of papers on even bi-unitary multiperfect numbers. In parts I, II and III we determined all bi-unitary triperfect numbers of the form $n=2^{a}u$, where $1\leq a \leq 6$ and $u$ is odd. In parts IV(a-b) we solved partly the case $a=7$. In this paper we fix the case $a=8$. In fact, we show that $n=57657600=2^{8}.3^{2}.5^{2}.7.11.13$ is the only bi-unitary triperfect number of the present type.
Refined enumeration of 2-noncrossing trees
Authors:   Department of Pure and Applied Mathematics, Maseno University, Okoth Isaac Owino
Published: June 2021

A 2-noncrossing tree is a connected graph without cycles that can be drawn in the plane with its vertices on the boundary of circle such that the edges are straight line segments that do not cross and all the vertices are coloured black and white with no ascent (i, j), where i and j are black vertices, in a path from the root. In this paper, we use generating functions to prove a formula that counts 2-noncrossing trees with a black root to take into account the number of white vertices of indegree greater than zero and black vertices. Here, the edges of the 2-noncrossing trees are oriented from a vertex of lower label towards a vertex of higher label. The formula is a refinement of the formula for the number of 2-noncrossing trees that was obtained by Yan and Liu and later on generalized by Pang and Lv. As a consequence of the refinement, we find an equivalent refinement for 2-noncrossing trees with a white root, among other results.

Using the theory of Pell equation, we study the non-trivial positive integer solutions of the Diophantine equations $z^2=f(x)^2\pm f(x)f(y)+f(y)^2$ for certain polynomials f(x), which mean to construct integral triangles with two sides given by the values of polynomials f(x) and f(y) with the intersection angle $120^\circ$ or $60^\circ$.
The Reasonable Balancing of Rights and Interests at the Time of Pandemic
Authors: Scalia Francesco
Published: June 2021

This essay starts with the consideration that the precautionary measures adopted by the Italian legislator and the public administration to deal with the pandemic emergency, while highly restrictive of constitutional freedoms, were commonly deemed reasonable and proportionate. It then
continues with some recent rulings of the Italian Constitutional Court. The analysis aims to show that the balance of rights implemented by the legislator and judged by the Court is affected by the state of emergency: the state of emergency makes reasonable what, in ordinary conditions, would
have been absolutely disproportionate. Proportionality, in fact – which is necessarily inherent to precautionary approach – finds a different balance point according to the context in which the precautionary measures are adopted. In 2006, Italy adopted its pandemic plan, which
was never updated as was required in accordance with the WHO guidelines formulated in 2017 and 2018. Nevertheless, the essay points out that the precautionary principle must not only shape the answer to the state of emergency, but also affect its planning and prevention. Moreover, the findings
show there was no lack of emergency forecasts or of measures suitable for the pandemic purpose, and that Italy had failed to implement these measures. Therefore, in the long term, the measures adopted by the Italian legislature and the public administration have turned out to be completely
unreasonable.
Opinion Piece – Terrorism, Human Trafficking and Conflict-Related Sexual Violence: Examining the Nexus
Authors: Attah Christiana Ejura
Published: June 2021

Terrorism, a global phenomenon afflicting virtually all continents in the world, has heightened trafficking in human beings. The same applies to the upsurge in sexual violence, especially in places with noticeable terrorist activities or experiencing other forms of conflict. The need
to determine whether this upsurge has any connection with terrorism or the activities of terrorist groups has not attracted the requisite scholarly interest. Terrorist organisations rely on human trafficking for a variety of reasons, while the trafficked victims are exposed to sexual violence
at the hands of members of these organisations. It raises a very important question: Is there a connection between terrorism, human trafficking and sexual violence in areas prone to conflict? This opinion piece examined the nexus between terrorism, human trafficking and conflict-related sexual
violence and concludes that a strong nexus exists between terrorism, human trafficking and conflict-related sexual violence as terrorism and the activities of terror groups provide the enabling environment for human trafficking and sexual violence to thrive. Furthermore, human trafficking
and conflictrelated sexual violence are interconnected as the former supplies the persons who end up as victims of the latter.
Sexual Slavery and Members of a Terrorist Group – What is the Future of the 'Boko Haram' Trial at the International Criminal Court?
Authors: Chadimova Michala
Published: June 2021

Crimes committed by the members of Boko Haram in Nigeria are not only the subject of national trials but also of preliminary examination at the International Criminal Court (ICC). This article focuses on the sexual slavery perpetrated by Boko Haram, describes how the crimes are viewed
within the national Nigerian criminal process and addresses the possibility of prosecution of the crimes at the ICC.
 This article analyses the legal terminology used to describe the crimes connected to Boko Haram – enslavement, sexual slavery, human trafficking and terrorism
– and their interaction. While providing an overview of the ICC's current preliminary examination into the situation in Nigeria, this article discusses how the principle of complementarity is potentially holding the OTP back from the formal investigation.
 Furthermore, an overview
of cases at the ICC that have involved charges of sexual slavery or enslavement will be provided. By analysing the Court's findings in relation to elements of sexual slavery, this article provides an insightful view into the Court's rhetoric on this crime. Similarly, this article discusses
modes of liability that have been employed in the Katanga/Chui and Ntaganda cases and provides a learning opportunity for future cases of sexual slavery as both a crime against humanity (Article 7(1)(g) of the Rome Statute) and a war crime (Article 8(2)(e)(vi) of the Rome Statute; 8(2)(b)(xxii)
of the Rome Statute).
Intersectionality: Explaining SGBV Interlinked with Terrorism and Other International Crimes
Authors: Martin Ana
Published: June 2021

Sexual and gender-based violence (SGBV) is often intertwined with and nested within other violations of international criminal law (ICL) as part of a broader attack against a group. However, ICL is not giving enough visibility to this nexus of crimes rooted in the intersection of identities
and discrimination that underpins SGBV during conflict. Intersectionality is a concept originated in feminism and progressively recognized by international human rights law (IHRL). It posits that SGBV is caused by gender 'inextricably linked' with other identities and factors that result in
compounded discrimination and unique aggravated harms. Based on case studies, this paper argues that ICL should integrate an intersectional approach based on identity and discrimination to address the nexus between SGBV and broader international crimes. Intersectionality enables a better understanding
of the causes, harms, and gravity of SGBV, and it provides consistency with an IHRL interpretation. The article begins setting out the foundations of intersectionality in feminism and IHRL, and its applicability to ICL. It then applies intersectionality to two case studies that demonstrate
the interlink of SGBV with broader violations of ICL: The Revolutionary United Front Case (RUF) trial judgment of the Special Court for Sierra Leone (SCSL) concerning SGBV and the war crime committing acts of terrorism, and Al Hassan, prosecuted at the International Criminal Court (ICC), concerning
SGBV and the crime against humanity of persecution. It concludes with final remarks on why and how ICL would benefit from integrating an intersectional approach to SGBV.

Background

Hepatocellular carcinoma (HCC) with high heterogeneity is one of the most frequent malignant tumors throughout the world. However, there is no research to establish a ferroptosis-related lncRNAs (FRlncRNAs) signature for the patients with HCC. Therefore, this study was designed to establish a novel FRlncRNAs signature to predict the survival of patients with HCC.

Method

The expression profiles of lncRNAs were acquired from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. FRlncRNAs co-expressed with ferroptosis-related genes were utilized to establish a signature. Cox regression was used to construct a novel three FRlncRNAs signature in the TCGA cohort, which was verified in the GEO validation cohort.

Results

Three differently expressed FRlncRNAs significantly associated with prognosis of HCC were identified, which composed a novel FRlncRNAs signature. According to the FRlncRNAs signature, the patients with HCC could be divided into low- and high-risk groups. Patients with HCC in the high-risk group displayed shorter overall survival (OS) contrasted with those in the low-risk group (P < 0.001 in TCGA cohort and P = 0.045 in GEO cohort). This signature could serve as a significantly independent predictor in Cox regression (multivariate HR > 1, P < 0.001), which was verified to a certain extent in the GEO cohort (univariate HR > 1, P < 0.05). Meanwhile, it was also a useful tool in predicting survival among each stratum of gender, age, grade, stage, and etiology,etc. This signature was connected with immune cell infiltration (i.e., Macrophage, Myeloid dendritic cell, and Neutrophil cell, etc.) and immune checkpoint blockade targets (PD-1, CTLA-4, and TIM-3).

Conclusion

The three FRlncRNAs might be potential therapeutic targets for patients, and their signature could be utilized for prognostic prediction in HCC.
