ASSESSMENT TOOLS IN TEACHING FOREIGN LANGUAGES FOR HIGHER EDUCATION: CHALLENGES OF GENERATION Z
Authors: Пупышева Мария Владимировна , Харитонова Мария Александровна
Published: June 2021

Обучение поколения Z в высшей школе должно быть адаптировано под его особенности, среди которых повышенная тревожность и отсутствие навыков долгосрочного прогнозирования. Данные черты снижают эффективность традиционного письменного контроля, уступая место более интерактивным игровым методам. Существуют инструменты, доказавшие свою эффективность для проведения текущего и промежуточного контроля, преимуществом которых является интуитивность их использования, а также сокращение времени подготовки и проверки работ обучающихся. Предлагаемые интерактивные инструменты контроля с использованием смартфона положительно сказываются на мотивации студентов, формируют правильное представление о собственном прогрессе и интегрируют цифровые технологии в учебный процесс, что само по себе уже является приоритетным направлением развития современной системы образования.

The article focuses on the effectiveness of traditional assessment tools applied in higher education for teaching generation Z, considering the fact that the new generation of students has its own characteristics, including increased anxiety and lack of long-term forecasting skills. These features, combined with the intuitive use of the Internet, reduce the effectiveness of traditional written tests, giving way to more interactive methods.
The authors suggest a number of modern tools suitable for the formative and summative assessment in both classroom and remote learning, highly demanded during the pandemic: Quizlet multimedia cards, Learningapps small interactive modules, the Edpuzzle platform for video files, online testing services of Kahoot! and Class Marker, as well as Mentimeter interactive presentations service. The indisputable advantage of the listed applications is their intuitiveness, and therefore they do not require long training for using them, and they also can reduce the time spent on the preparation and evaluation of students’ tests.
The proposed interactive assessment tools imply an active use of smartphones by students and have a positive effect on their motivation, help them form a proper idea of their own progress and integrate digital technologies into the educational process, which in itself is already a priority for the modern education system.

Authors: Егоров Константин Борисович , Захарова Вера Анатольевна
Published: June 2021

Дается независимая оценка преимуществам и недостаткам в формировании регулятивных умений младших школьников и умений самоорганизации учителей в дистанционном обучении в период пандемии в 2020 г. Экстренный переход на дистанционное обучение вызвал трудности в преподавании и учении. Во многом эти сложности обусловлены недостаточным уровнем регулятивных умений учеников и учителей.
Сопоставляются результаты двух эмпирических исследований, проведенных Пермским государственным гуманитарно-педагогическим университетом: диагностики регулятивных умений младших школьников в 2018–2021 гг. и оценки учителями начальных классов проблем самоорганизации в период дистанционного обучения в 2020 г. По итогам независимой оценки предложены рекомендации по развитию профессиональных компетенций учителей начальных классов.

The purpose of the article is an external evaluation of the advantages and disadvantages of the primary school students’ self-management skills and teachers’ self-management skills during the distance learning time of pandemic-2020.
The emergency transition to distance learning has caused difficulties in teaching and learning. Probably these difficulties are due to the insufficient level of students’ and teachers’ self-management skills.
Data includes the results of two empirical studies carried out by the Perm State Humanitarian Pedagogical University. First, results of diagnostics of the primary school students’ self-management skills in 2018–2021 years. Students of the 2nd, 3rd and 4th grades of Perm region schools participated in the diagnosis. Criterion-oriented diagnostics based on everyday situations in the logic of functional literacy assessment. Secondly, primary school teacher’s self-assessment of the problems of organizing distance learning during the pandemic-2020. A focus group of 79 primary school teachers took part in the semi-structured Internet survey.
The results of the study show that primary school teachers were not ready for distance teaching. The teachers’ work time has increased, caused by mastering distance tools and new conditions for self-regulation. The need of special attention for self-management students’ skills was identified. Certain students’ self-management skills were important for distance learning, such as planning, self-control and self-esteem, the choice of effective methods of action. The teacher’ training also is required to be focused on assessment skills, applying of automated control tools, developing of students’ self- and peer- assessment skills in a digital environment. Based on the results of an external evaluation, the authors suggest developing the primary school teachers’ professional competencies.

Published: June 2021

Рассматривается процесс становления педагогического сопровождения слепых учащихся с тяжелыми множественными нарушениями развития (на примере слепоглухих) в России и Сибири в период до революции 1917 г. и по настоящее время. Для понимания современного состояния проблемы обучения и педагогического сопровождения слепых учащихся с тяжелыми множественными нарушениями развития необходимо знать ее историю. Данное историко-педагогическое исследование позволяет проследить динамику становления специальных институтов в хронологическом порядке от зарождения до настоящего времени. Отмечено, что становление подобных учреждений состоялось на благотворительной основе без государственной финансовой поддержки. Показана роль Всероссийского общества слепых по организации трудоустройства слепых взрослых людей в 1930-е гг. и современное состояние реабилитационных центров. Рассмотрено возникновение научных школ и их роль в разработке содержания и методов обучения слепых и слепоглухих детей. Подчеркнуто, что интерес науки к обучению слепых зарождался очень медленно. Только к середине ХХ в. появилась сеть государственных специальных учреждений для слепых, слабослышащих и слепоглухих детей. Отмечены выдающиеся ученые и педагоги, оставившие значительный вклад в тифлопедагогике.

This article presents the process of development of pedagogical support of visually impaired learners with multiple severe developmental disorders (exemplified by deafblind learners), including visually impaired learners in Russia and Siberia, starting prior to the revolution of 1917 until the present day. Experience has proven it is essential to know the history of pedagogical support of visually impaired learners with multiple severe developmental disorders to gain a better understanding of the current status of the subject. This pedagogical research allows you to trace the dynamics of the formation of special institutions in chronological order from the beginning to the present time. The establishment of such institutions took place on charitable basis without state financial support. The role of the All-Russian Society of the Blind in organizing the employment of blind adults and current status of rehabilitation centers are shown.
The article considers the emergence of scientific schools and their role in the development of the content and methods of teaching blind and deafblind children. Pedagogical and typhlopedagogical developments that occurred many years ago leave a significant mark in science.
It is emphasized that the interest of science in teaching the blind was born very slowly. Only by the middle of the twentieth century a network of state special institutions for blind and deafblind children has appeared. Some prominent scientists and teachers who have made a valuable contribution to typhlopedagogy are noted.

Objective. This evidence report synthesizes the available evidence on radiation therapy for brain metastases. Data sources. We searched PubMed®, Embase®, Web of Science, Scopus, CINAHL®, clinicaltrials.gov, and published guidelines in July 2020; assessed independently submitted data; consulted with experts; and contacted authors. Review methods. The protocol was informed by Key Informants. The systematic review was supported by a Technical Expert Panel and is registered in PROSPERO (CRD42020168260). Two reviewers independently screened citations; data were abstracted by one reviewer and checked by an experienced reviewer. We included randomized controlled trials (RCTs) and large observational studies (for safety assessments), evaluating whole brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS) alone or in combination, as initial or postoperative treatment, with or without systemic therapy for adults with brain metastases due to non-small cell lung cancer, breast cancer, or melanoma. Results. In total, 97 studies, reported in 190 publications, were identified, but the number of analyses was limited due to different intervention and comparator combinations as well as insufficient reporting of outcome data. Risk of bias varied; 25 trials were terminated early, predominantly due to poor accrual. Most studies evaluated WBRT, alone or in combination with SRS, as initial treatment; 10 RCTs reported on post-surgical interventions. The combination treatment SRS plus WBRT compared to SRS alone or WBRT alone showed no statistically significant difference in overall survival (hazard ratio [HR], 1.09; confidence interval [CI], 0.69 to 1.73; 4 RCTs; low strength of evidence [SoE]) or death due to brain metastases (relative risk [RR], 0.93; CI, 0.48 to 1.81; 3 RCTs; low SoE). Radiation therapy after surgery did not improve overall survival compared with surgery alone (HR, 0.98; CI, 0.76 to 1.26; 5 RCTs; moderate SoE). Data for quality of life, functional status, and cognitive effects were insufficient to determine effects of WBRT, SRS, or post-surgical interventions. We did not find systematic differences across interventions in serious adverse events radiation necrosis, fatigue, or seizures (all low or moderate SoE). WBRT plus systemic therapy (RR, 1.44; CI, 1.03 to 2.00; 14 studies; moderate SoE) was associated with increased risks for vomiting compared to WBRT alone. Conclusion. Despite the substantial research literature on radiation therapy, comparative effectiveness information is limited. There is a need for more data on patient-relevant outcomes such as quality of life, functional status, and cognitive effects.

Authors: Arafani Adnan , Handrianto Ciptro , Uçar Ahmet Serhat , Karneli Yeni
Published: June 2021

The adolescent problems discussed in individual counselling sessions vary widely. The approach the counsellor uses has an effect on the way the problem is solved and the follow-up determines the recurrence of the same problem. The use of Rational Emotive Behavior Therapy focuses on aspects of irrational thinking as the root of individual problems. This article examines the case of a teenager and then determines the existing irrational thought patterns. This study uses a qualitative case study method by analyzing the counselling process. This study concluded that adolescents with emotional maturity tend to be potentially irrational by "demanding" and "awfulizing". This article recommends that educators outside of school and at school improve the rational thinking skills of adolescents through various awareness education.

Authors: Dasa Putri Lili
Published: June 2021

Excessive works and routines carried out either by children, adults, or parents can lead to boredom so that they need the means to make them fresh. Many things can be done to restore the spirit and make them refresh, starting from sports, recreation, and so on. Nowadays, car free day in several cities is getting attention in Indonesia. It is usually conducted on the weekend both in small cities and big cities. There are many things that can be done and enjoyed during the car free day, and all ages can enjoy it. A car free day can be a form of educational tourism because it provides many educational contents directly or indirectly. Besides, on the car free day, visitors can also enjoy a variety of local, national, and even international culinary delights. Besides being able to refresh, on a car free day, people can also get daily necessities because many sellers can be found there and sell various types of goods. Therefore, the car free day deserves to be an alternative for educational tourism for families.
Beyond Polaroid: Visual Rhetoric in Shaping Refugee’s Identity
Authors: John Donna
Published: June 2021

Photographs tend to have an ability to influence the collective consciousness of humanity. Sonja K. Foss, a rhetorical educator, opines that language is general while images are concrete and specific. Many a time, photographs have become spokespersons of the suffering and needy lot. Throughout its history, photography has created opinions, constructed realities of people and brought human tragedies to the forefront. The refugee crisis is in no way an exception. In fact, the conscience of the whole world in regard to the refugees was awakened by an appalling photograph of a three-year-old Syrian toddler, Aylan Kurdi, lying face-down into the sand. Such photographs, often symbolic and termed as visual rhetoric, slowly turned into stereotypes defining the refugee crisis. This paper discusses on how these visual narratives have shaped the identity of refugees and created various regimes of seeing.

Published: June 2021

The purpose of the study is to consider the legal regulation of railway freight transportation (on the example of Russia and some European countries), as well as study the peculiarities of criminal prosecution for disabling communication lines or transport on the example of the legislation of the Russian Federation. The leading method was the deductive. The method of systems analysis, the historical method, the method of induction, etc. were used. The study concludes that today, an increase in transport significantly increases the prevalence and danger of crimes that encroach on the functioning of transport that is safe for people and society. The chapter uniting these crimes is located in Section IX of the Criminal Code of the Russian Federation: “Crimes against Public Safety and Public Order”, placed in third place after the section on crimes against the person and in the economic sphere.
Research Ethics: A Perspective of South Asian Context
Authors:   Kathmandu University School of Education, Nepal, Dahal Bibek
Published: June 2021

Research ethics is concerned with ethical issues that can arise while conducting research. Social science research entails a combination of three equal entities: process, context and human agency. In each study, these entities demand rich interaction with each other. Generally, research ethics questions the interrelation between the research context and the human involvement established within that context. The research context and interaction between researcher and research participants lead to variations in the construction of knowledge, while research ethics plays a major role throughout all undertakings. In this narrative review paper, I have critically reflected my arguments on behalf of research ethics as a context-specific issue. I argued that the one-size-fits-all approach of research ethics is not viable by presenting ethical practices from the South Asian perspective. The paper is organized in three specific sections – ethical theories, research ethics and its contextual practices. Research ethics is very much a private affair and directly linked to the personal outlook of the researcher towards others. The ethical issue in research is not generic, but specific to the research context, i.e. the context of the research determines what form of behaviour is ethical and what is not. I explore the idea that the South Asian context may have its own system to conduct research ethically, as in euro-western and indigenous systems.

The article presents academics’ perceptions on research integrity and teaching integrity and ethics. The empirical basis of the article is a qualitative analysis of data based on open questions from two online surveys conducted among scientists, academic teachers and students. We point out two ways of defining scientific integrity: (1) as a common challenge for the academic community arising from the relationship between science and society; (2) as an individual choice and one’s capital in achieving scientific success. We describe the respondents’ views on the process of teaching integrity and ethics, rooted in a values-based approach to integrity. In this approach, teaching is open to the use of dialogical methods and takes into account the relative nature of the subjects being taught – research integrity and ethics. In our analyses, we focus on a positive approach to research integrity and show that it has great potential to raise the awareness of the scientific community about the principal values in science.
Los perros y su estrecho vínculo con las personas ¿Qué los hace únicos?
Authors: Barrera Gabriela , Bentosela Mariana
Published: June 2021

A lo largo de sus vidas los perros tienen la capacidad de formar fuertes vínculos afectivos con los humanos. Además de apegarse a sus cuidadores, pueden relacionarse de manera exitosa con personas desconocidas. Se han descrito una serie de características psicológicas generales de los perros que estarían en la base de este vínculo y que habrían posibilitado el desarrollo de complejas habilidades socio-cognitivas en los mismos. En el presente trabajo se describen y se analizan las evidencias con respecto a tres de esas capacidades generales: la sociabilidad, la docilidad y la habilidad de sincronización con las personas. Estas se han propuesto como factores importantes de selección durante el proceso de domesticación y mostraron además ser flexibles y modificarse durante la ontogenia. Se discuten diversos abordajes que permiten estudiar la importancia que tienen dichas características, junto a otros rasgos, para el desarrollo de un vínculo único entre perros y personas.

Authors: Seo Gang-Hoon , Itoh Munehiko , Li Zhonghui
Published: June 2021

For the last several decades, global airline alliances have ensured their market presence in the aviation industry. Scholars have focused on the effects of alliance affiliation for airlines and what the competitive advantages of alliances are. However, these issues have been discussed in relation to operational aspects. The quality of strategic communication can be an important factor in achieving a competitive advantage and realizing a differentiation strategy. This study assessed the differences in quality of strategic communication between the three leading alliance groups (oneworld, SkyTeam, and Star Alliance) and a non-alliance group. Comprehensive content analysis was implemented using the letters of chief executive officers (CEOs) of 46 airlines. We found that the non-alliance group has more ideal CEO letters than the alliance groups, and the main topics and quality of CEO letters of alliance group differed. This study provides a novel insight into the competitive advantage of global airline alliances.

Independent verification of treatment planning system calculations
Authors: Dąbrowska-Szewczyk Edyta , Zawadzka Anna , Brzozowska Beata , Walewska Agnieszka , Kukołowicz Paweł
Published: June 2021

Purpose

According to the available international recommendations, at least one independent verification of the calculations of number of monitor unit (MU) is required for every patient treated by teleradiotherapy. The aim of this study was to estimate the differences of dose distributions calculated with two treatment planning systems: Eclipse (Varian) and Oncentra MasterPlan (Elekta).

Materials and methods

The analysis was performed for 280 three-dimensional conformal radiotherapy treatment (3D-CRT) plans with photon beams from Varian accelerators: CL 600C/D X6 MV (109 plans), CL 2300C/D X6 MV (43 plans), and CL 2300C/D X15 MV (128 plans). The mean doses in the planning target volume (PTV) and doses at the isocenter point obtained with Eclipse and Oncentra MasterPlan (OMP) were compared with Wilcoxon matched-pairs signed rank test. Additionally, the treatment planning system (TPS) calculations were compared with dosimetric measurements performed in the inhomogeneous phantom.

Results

Data were analysed for 6 MV plans and for 15 MV plans separately, independently of the treatment machine. The dose values calculated in Eclipse were significantly (p <0.001) higher compared to calculations of OMP system. The average difference of the mean dose to PTV was (1.4 ± 1.0)% for X6 MV and (2.5 ± 0.6)% for X15 MV. Average dose disparities at the isocenter point were (1.3 ± 1.9)% and (2.1 ± 1.0)% for X6 MV and X15 MV beams, respectively. The largest differences were observed in lungs, air cavities, and bone structures. Moreover the variation in dosimetric measurements was less as compared to Eclipse calculations.

Conclusions

OMP calculations were introduced as the independent MU verification tool with the first action level range equal to 3.5%.

Authors: Wang Yuan , Zhang Miao , Song Tong , Chang Zhenqi
Published: June 2021

A new kind of 125I seeds with a core-shell structure were synthesized by an easy assembling–disassembling coaxial capillaries microfluidic device. The dose distribution of a 125I brachytherapy source fabricated by arranging six 125I seeds collinearly within a cylindrical titanium capsule was simulated by modelling the source in a water phantom using Monte Carlo N-Particle Transport code. The influence of the motion and the core size of the 125I seeds on the dose distribution was also studied in this work.

Published: June 2021

Actinium-225 is used in nuclear medicine for the treatment of malignant tumours. It can be applied to produce Bi-213 in a reusable generator or can be used alone as an agent for radiation therapy, in particular for targeted alpha therapy. However, the availability of Ac-225 for worldwide use, particularly in low- and middle-income countries, is limited. We present a feasibility study employing GATE, an open-source Monte Carlo simulation toolkit, on the production of Ac-225 from a neutron generator. This work suggests that a design consisting of three concentric cylinders, the innermost a Cf-252 neutron source, the middle nickel cylinder acting as a proton-producing target and the outer cylinder a RaCl2 target may provide a feasible design outline for an Ac-225 generator.
Validation of transient time method to calibrate oil flow meters in closed conduits using 123I as the radiotracer
Authors: Gonçalves Eduardo R. , Brandão Luís E. B. , Braz Delson
Published: June 2021

To assure the credibility of commodity transfer operations in the oil and gas industry, calibrated flow meters are used to quantify the movement of fluids in the pipelines. The purpose of this paper is to validate the transient time method (TTM) to calibrate oil flow meters installed in restricted areas, using the 123I-labelled oil as a radiotracer. Traditionally, as proposed by the standard ISO 2975-7:1977 [1] for experiments in an aqueous medium, the TTM is employed by positioning two detectors at separate locations. However, in industrial plants, it is not always possible to install detectors at the distances recommended by the ISO 2975-7. The method proposed in this paper uses four scintillator detectors separated one from each other by 0.30 m and three injections containing 5.0 ml of 123I-labelled oil. The experiments were carried out in an oil flow rig with a turbulent flow profile. The results have reached an uncertainty which is lower than 1.0%.

Why is there an implementation gap in community energy planning?
Authors: Murphy Rose , Pardy Aaron , Braglewicz Morgan , Zuehlke Brett , Jaccard Mark
Published: June 2021

In community energy planning, a persistent disconnect has been observed between the targets and plans announced by local governments and the application of effective policy to reduce energy consumption and greenhouse gas (GHG) emissions. We use two methods to explore this implementation gap. First, we apply energy-economy modelling tools at the urban level to evaluate the effectiveness of various policy options available to local governments. Our case study for these exercises is the leading jurisdiction of Vancouver, British Columbia. Second, we report and analyze the results of a survey we administered to community energy practitioners in Canada. The modelling results point to jurisdictional reach as an important contributor to the implementation gap. We find that, while Vancouver can make significant progress by implementing policies that are clearly within its jurisdiction, the city is unlikely to meet its ambitious renewable energy and GHG emissions targets without the support of higher levels of government. The survey responses suggest that capacity limitations of local government also have a role in perpetuating the implementation gap.
An investigation into barriers to student engagement in Higher Education: Evidence supporting 'the psychosocial and academic trust alienation theory’
Authors:   Education Faculty, Manchester Metropolitan University, Manchester, UK, Jones Caroline Sarah
Published: June 2021

The purpose of this research was to examine the new concept of, ‘psychosocial and academic trust alienation theory’; the potential influence of self-concept, self-esteem and trust as barriers to student engagement. The study was conducted in a Higher Education University campus located within a 16-19 year old Further Education Institution.A constructivist epistemology, underpinned by symbolic interaction theory utilising a mixed methods approach formed the research design. The sample population were students enrolled at the participating institution and employed teaching staff. Quantitative surveys were completed by 39 students, supported by two qualitative staff focus groups and one qualitative student case study to examine an outlier result. Findings suggest 87% of the student participant sample aligned with the ‘psychosocial and academic trust alienation theory’. Barriers to student engagement were; specific classroom and assessment activities, relationships with teaching staff and peers, staff absences and staff turnover, all having a significant impact on students’ psychosocial and academic trust. The contribution of this research to the field of Higher Education is three-fold; firstly, findings support the ‘psychosocial and academic trust alienation theory’, secondly it provides insights into the psychological barriers to engagement for the Widening Participation student demographic, thirdly it proposes practical strategies for supporting Widening Participation students in Higher Education. Recommendations for practice include i) counselling, coaching and mentoring support from teaching staff, ii) initiatives to reduce staff turnover and sickness, iii) social pedagogical teaching approaches, iv) teacher training, and, v) peer based learning opportunities to cultivate communities of practice. These strategies could strengthen Widening Participation student’s psychosocial and academic trust, thus reducing barriers to student engagement in Higher Education, contributing to increased social mobility success rates in the United Kingdom and beyond.

Authors: Gadelrab Hesham F.
Published: June 2021

Introduction. The purpose of this study is double. First, to evaluate the factorial structure of Approaches and Study Skills Inventory for Students (ASSIST) as a measure of approaches to learning with bilingual Egyptian higher education students by testing the plausibility of reproducing its intended three-factor structure. Second, the study aimed at testing the predictive validity of ASSIST.Method. The sample of the study consisted of (n=516) college students from one international university in Egypt. To cross-validate the factor structure, the subjects were divided into two equal samples. Confirmatory factor analysis was used to test the structure of ASSIST.Results. The findings of this study confirmed the underlying constructs of three distinctive approaches to learning. ASSIST main scales and subscales’ scores showed appropriate internal consistency and predictive validity to academic achievement.Conclusion. It was concluded that ASSIST is a valid research tool for the assessment of approaches to learning, however caution should be taken with respect to the interpretation of particular subscales and possible sample effects.
Crip Collectivity Beyond Neoliberalism in Octavia Butler’s Parable of the Sower
Authors: Whatcott Jess
Published: June 2021

The importance of Octavia Butler’s 1993 novel Parable of the Sower continues to crystalize, as Butler’s prescient imagining of urban California torn apart by neoliberal divestment comes to fruition. Following in the space opened up by Black feminist scholarship on Butler, the present essay examines her relevance beyond literary and cultural studies. I argue that Parable is a Black feminist crip theorization of political economy that diagnoses the disabling conditions of precarity under neoliberalism and also prescribes collectivity for crip and mad survival. Neoliberalism describes a global stage of advanced capitalism wherein governments are both incentivized and disciplined into enforcing economic policies that include privatization, deregulation, and market liberalization. As Jodi Melamed defines it, neoliberalism requires a certain kind of political governance, that puts the interests of business over the well-being of people (2011). Neoliberal governance engenders what I call “disabling contradictions,” yet the blame for conditions of precarity is deflected onto bodyminds themselves. In Parable of the Sower, Butler theorizes these disabling contradictions of neoliberal governance under advanced capitalism, drawing into focus the political economic systems that cause suffering. Parable also depicts strategies for crip and mad survival that are made possible through the conscious creation of community and networks of solidarity that counter the neoliberal state’s devaluation of bodyminds. Gathering to read and discuss the novel, rather than a distraction from the crises, furthers the emergence of crip and mad collectivities. As such, it is an urgent and timely practice for building futures for crip and mad people.
The Myths of Haji Firuz
Authors: Baghoolizadeh Beeta
Published: June 2021

Every year, around the arrival of the Spring equinox, Iranians in Iran and in diaspora will recognize a minstrel named Haji Firuz with his Nowruz jingle. The inclusion of Haji Firuz during Nowruz festivities has been questioned and challenged for decades; where some will point out his connections to anti-Blackness, others will defend Haji Firuz, arguing that his face is only covered in soot from fires also associated with the holiday. This article contextualizes these arguments as a part of a larger discourse of denying racism in Iran and, more poignantly, erasing Iran’s history of slavery altogether. This article addresses the consequences and pitfalls of defending Haji Firuz’s blackface performance, and its implications for the broader Iranian community.
An (Un)Marked Foreigner
Authors: Silverstein Shayna , Sprengel Darci
Published: June 2021

This essay negotiates the critical tension between race as an analytic and social construct by examining how race becomes socialized in and through the production and presentation of Arab culture in two ethnographic case studies: how Syrian musicians negotiate musical multiculturalism as they integrate into German society and how independent musicians in Egypt navigate the racialized entanglements of national and international security logics that privilege Western foreigners. Both these case studies center the “foreigner” subject as one who embodies proximity to white power and delimits the boundaries of such power. We argue that the category of foreigner is thus a racialized construct that not only complicates the Black–white binary of race relations but strategically evades explicit discourses and practices of racecraft that are violent, discriminatory, and exclusionary. By provincializing critical race theory through the particularities of Arab lived experience, we illustrate how local social categories are entangled with historic legacies of empire and contemporary global logics of racialized difference while remaining sensitive to how conceptions of difference exceed Euro-American categories of race. Our work therefore directs attention towards alternative enactments of racialization within the Global South.
Review of Bans, Walls, Raids, Sanctuary: Understanding U.S. Immigration for the Twenty-First Century by A. Naomi Paik (University of California Press)
Authors: Franks Travis
Published: June 2021

A. Naomi Paik’s Bans, Walls, Raids, Sanctuary responds to a trio of executive orders on immigration policy issued in the early days of Donald Trump’s presidency. Those orders sought to make good on campaign promises to further restrict immigration by banning citizens from Muslim-majority countries, allocating funds to expand a border wall between the US and Mexico, and ramping up home and workplace deportation raids by Immigration and Customs Enforcement (ICE). Paik delineates how these legal barriers came to be by locating them in relation to the nation’s formative immigration policies, backlash to the liberation movements of the 1960s and 1970s, and the global repercussions of neoliberalism. Highlighting the work of Indigenous activists, Paik eventually calls not only for the dramatic restructuring of the nation’s immigration system but also for the creation of a more just society based on relationships that reject the politics of inclusion and exclusion.
“A Program of Complete Disorder”
Authors: Athanasopoulos Charles
Published: June 2021

This essay examines the scholarship of revolutionary theorist Frantz Fanon and the debate surrounding his conception of decolonization and “new humanism.” Across a multitude of fields, Black and cultural studies among them, Fanon has been heralded as an iconic thinker who offers us a path toward an alternative humanity. Working against the grain of this popular form of Fanonism, I suggest that there is a Black iconoclasm—a deep desire to unsettle the very rendering of a systematic path toward decolonization—that pervades Fanonian thought. Accordingly, the essay examines and unsettles various forms of Fanonism by suggesting that their teleological narratives of redemption ultimately end up serving anti-Fanonian pursuits. Through an extended meditation on Fanon’s claim that decolonization is “a program of complete disorder,” I explore what it might mean to embrace a Black iconoclastic approach to Fanon and the pursuit of Black liberation.
