Base change for ramified unitary groups:
The strongly ramified case
Authors: Blondel Corinne , Tam Geo Kam-Fai
Published: January 2021

We compute a special case of base change of certain supercuspidal representations from a
ramified unitary group to a general linear group, both defined over a p-adic field of odd residual characteristic. In this special case, we require the given supercuspidal representation to contain a skew maximal simple stratum, and the field datum of this stratum to be of maximal degree, tamely ramified over the base field, and quadratic ramified over its subfield fixed by the Galois involution that defines the unitary group. The base change of this supercuspidal representation is described by a canonical lifting of its underlying simple character, together with the base change of the level-zero component of its inducing cuspidal type, modified by a sign attached to a quadratic Gauss sum defined by the internal structure of the simple character. To obtain this result, we study the reducibility points of a parabolic induction and the corresponding module over the affine Hecke algebra, defined by the covering type over the product of types of the given supercuspidal representation and of a candidate of its base change.
Sustainable nanocomposite films based on SiO2 and biodegradable poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) for food packaging
Authors: Qiu Yujuan , Fu Jirui , Sun Binqing , Ma Xiaojun
Published: January 2021

Sustainable nanocomposites with transparent, biodegradable, and enhanced mechanical and barrier properties were prepared by the incorporation of SiO2 into poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) films and subsequent solvent casting. The crystallinity of composites could be increased by 67% with appropriate contents of SiO2, which proved that SiO2 were effective nucleating agents for PHBH. And it was worth mentioning that the contributions of SiO2 to the crystallization and thermal stability of composites are proved effectively by Avrami relationship and Horowitz and Metzger method. More importantly, compared with PHBH, it had not only an enhancement about 40% and 60% on the tensile strength and elastic modulus, respectively, but also half the reduction of the moisture and oxygen permeability which were much higher than the values of conventional plastics. The above, in conjunction with the low migration rate measured in food substitutes, illustrated unambiguously that the nanocomposites might be suitable for potential application in food packaging.

Studies of Penicillium species associated with blue mold disease of grapes and management through plant essential oils as non-hazardous botanical fungicides
Authors: Ghuffar Salman , Irshad Gulshan , Naz Farah , Khan Muhammad Azam
Published: January 2021

Blue mold caused by Penicillium species is a major fungal disease threatening the viticulture industry in Pakistan, responsible for deteriorating the quality of grapes during handling, transportation, and distribution. Identification-based approaches of Penicillium species provide a better strategy on accurate diagnosis and effective management. In this study, 13 isolates were recovered from symptomatic grape bunches at five main fruit markets of Rawalpindi district, Punjab province. Based on morphological data and multi-loci phylogenetic analysis, the isolates were identified as two distinct species viz. Penicillium expansum (eight isolates) and Penicillium crustosum (five isolates). Meanwhile, the pathogenicity test of Penicillium isolates presented by the inoculation of grape bunches showed various degrees of severity. For improving the fruit quality and eliminating the needs of synthetic fungicides, botanicals such as thyme (Thymus vulgaris L.), fennel (Foeniculum vulgare L.), garlic (Allium sativum L.), ginger (Zingiber officinale L.), and carum (Carum capticum L.) essential oils (EOs) at concentrations of 0.6, 0.9, 1.2, and 1.5 mg/mL were evaluated. In vitro studies indicated that thyme EO showed a highly significant reduction of fungal growth. Furthermore, the experiments related to reducing the decay development and average weight loss percentage of grapes revealed similar findings. Based on the results of this study, it is recommended that thyme EO can be used as an eco-friendly botanical fungicide against Penicillium spp. causing blue mold disease.
Attitudes of students at the faculty of Regional Development and International Studies toward plagiarism
Authors: Smolík Josef , Herbočková Lucie
Published: January 2021

This study aims to identify student attitudes to and perceptions of the topical phenomenon of plagiarism at the Faculty of Regional Development and International Studies at Mendel University in Brno, Czech Republic. The paper includes a theoretical framework describing plagiarism, academic ethics and provides a different perspective on plagiarism by many authors. Furthermore, the article presents a semi-structured questionnaire conducted in July 2018 with a sample of 235 respondents. The questionnaire was used in this research to explore students’ personal experiences, recommendations and other information relating to their attitudes to and perceptions of plagiarism. The results indicate that FRDIS students were familiar with the concept of plagiarism but not always able to clearly identify the correct answers. The recommendation for the Faculty, based on the data analysis, is to hold a tutorial on all the important aspects of plagiarism, such as citations, referencing, and common mistakes. This paper concludes that plagiarism can only be eliminated if it is tackled at the prevention phase, not merely through the use of warnings and threats.
Collective subjects and political mobilization in the public space: Towards a multitude capable of generating transformative practices
Authors: Belli Simone , Raventós Cristian López
Published: January 2021

During the last twenty years in Latin America, there has been a rise in governments drawn from self-defining progressive political currents. Consequently a revitalization is underway of the debate on the viability, pertinence, and characteristics of the welfare state in the twenty-first century. In this context, the present article explores emerging social practices that redefine the various senses of the public space; practices that go beyond nation states, situated in a global territoriality, articulating languages and eliciting emotions capable of producing new socialities. The multitude is discussed as a social subject capable of generating transformative practices. Specifically, the article analyzes the way in which the singularities of occupations raise further questions for nation states. The analysis focuses on global movements such as #Occupy camping out on squares.
The failure of the welfare ideology and system in Hong Kong: A historical perspective
Authors: Yu Andrew
Published: January 2021

At present, Hong Kong does not have a publicly-managed mandatory contributory retirement protection scheme. The Hong Kong Government launched a consultation on the universal pension scheme in 2015. The Government’s plan provoked many controversies and eventually failed. This paper will examine the problem of the welfare ideology and system in Hong Kong from a historical perspective, taking the universal pension scheme as an example. This paper argues that the reason for the failure of the universal pension scheme was that Hong Kong people do not have a complete sense of citizenship and hold a distorted welfare ideology for historical reasons. This paper is one of the first to offer some reflections on the question of poverty and lack of social justice from a historical perspective.

Generation of renewable energy sources and their interfacing to the main system has turn out to be most fascinating challenge. Renewable energy generation requires stable and reliable incorporation of energy to the low or medium voltage networks. This paper presents the microgrid modeling as an alternative and feasible power supply for Institute of Technology, Hawassa University, Ethiopia. This microgrid consists of a 60 kW photo voltaic (PV) and a 20 kW wind turbine (WT) system; that is linked to the electrical distribution system of the campus by a 3-phase pulse width modulation scheme based voltage source inverters (VSI) and supplying power to the university buildings. The main challenge in this work is related to the interconnection of microgrid with utility grid, using 3-phase VSI controller. The PV and WT of the microgrid are controlled in active and reactive power (PQ) control mode during grid connected operation and in voltage/frequency (V/F) control mode, when the microgrid is switched to the stand-alone operation. To demonstrate the feasibility of proposed microgrid model, MATLAB/Simulink software has been employed. The performance of fully functioning microgrid is analyzed and simulated for a number of operating conditions. Simulation results supported the usefulness of developed microgrid in both mode of operation.
Enhancement of system performance using STATCOM as dynamic compensator with squirrel cage induction generator (SCIG) based microgrid
Authors: Saxena Nitin Kumar , Kumar Ashwani , Gupta Varun
Published: January 2021

Value based services are the new emerging area in Indian Electricity Market. Technically, such value added services in the electricity market are known as Ancillary Services. Voltage Control Ancillary Service (VCAS) deals with local level voltage control problem of power sector. According to IEEE standards 1159:1995, 1250:2011, only ±5% voltage variation is allowed with almost 0 deviations in frequency (±0.03% maximum variation limit) to interconnect any new generating plant with a grid. The utilization of squirrel cage induction generators (SCIG) as wind operated micro grid may be in a fix without adequate availability of reactive power. Besides SCIG, load changes also cause voltage varying problems and so, this paper investigates how load change can be coped up with fast acting reactive power compensator for such arrangements. To demonstrate this real time Simulink models for fixed capacitor and STATCOM are developed using MATLAB software. The SCIG starting and load change conditions are tested with fixed capacitor, six and 12 pulse STATCOM as reactive power compensators. The SCIG performances in terms of rotor speed, voltage, and frequency control characteristics during starting of the machine as well as at the time of load perturbation are compared.
Teaching evidence-based practice piece by PEACE
Authors: Emich Cheryl
Published: January 2021

Teaching evidence-based practice (EBP) to nurse practitioner (NP) students creates a challenge. Practicing NPs are frequently called upon to develop EBP protocols and therefore, must be proficient in defining clinical problems, retrieving and appraising evidence, implementing protocols to change practice based on evidence, and evaluating the practice changes. A new faculty team integrated the constructivist approach using the PEACE framework to rebuild the EBP course. Course modules corresponded to each letter of the PEACE framework: problem identification, evidence retrieval, appraisal of evidence, changing practice or conducting more research, and evaluation. Students collaborated with a non-nursing professional as part of the college’s commitment to interprofessional learning. Following the PEACE framework, students created an evidence-based poster of a proposed clinical practice change. Feedback from faculty and students was positive. Areas for improvement included eliminating redundancy in module content, standardizing all grading rubrics, and adding more virtual sessions for student/faculty interaction.
A companding approach for PAPR suppression in OFDM based massive MIMO system
Authors: Yadav Ajay Kumar , Sahoo Pritam Keshari , Prajapati Yogendra Kumar
Published: January 2021

Orthogonal frequency division multiplexing (OFDM) based massive multiuser (MU) multiple input multiple output (MIMO) system is popularly known as high peak-to-average power ratio (PAPR) issue. The OFDM-based massive MIMO system exhibits large number of antennas at Base Station (BS) due to the use of large number of high-power amplifiers (HPA). High PAPR causes HPAs to work in a nonlinear region, and hardware cost of nonlinear HPAs are very high and also power inefficient. Hence, to tackle this problem, this manuscript suggests a novel scheme based on the joint MU precoding and PAPR minimization (PP) expressed as a convex optimization problem solved by steepest gradient descent (GD) with μ-law companding approach. Therefore, we develop a new scheme mentioned to as MU-PP-GDs with μ-law companding to minimize PAPR by compressing and enlarging of massive MIMO OFDM signals simultaneously. At CCDF = 10−3, the proposed scheme (MU-PP-GDs with μ-law companding for Iterations = 100) minimizes the PAPR to 3.70 dB which is better than that of MU-PP-GDs, (iteration = 100) as shown in simulation results.
Cape Town Gujarati and its relation to Gujarati dialectology: A study of retroflex boosting
Authors: Mesthrie Rajend , Chavda Vinu
Published: January 2021

This paper has two purposes. Firstly, it provides a bird’s eye view of the characteristics of a variety of Gujarati in diaspora, viz. that spoken in Cape Town, South Africa for almost 150 years. Secondly it focusses on one notable feature, viz. the prominence of retroflexes over dentals, and connects this with other dialects of Gujarati in India and with Western Indo-Aryan. We analyse the speech of 32 speakers born or brought up in South Africa, and resident in Cape Town. We show that Cape Town Gujarati retains the dialect variation of late nineteenth century Gujarati as identified by Grierson, Sir George A. 1908. Linguistic survey of India. Vol IX, part II: Indo-Aryan family, Central Group – Rajasthani and Gujarati. Delhi: Motilal Banarsidass. In particular, it resembles the Surti dialect, in keeping with the fact that the area around Surat district provided the bulk of migrants to Cape Town in the nineteenth and twentieth century. We then focus in detail on a prominent, but little-studied, phenomenon of Gujarati dialects: the variable occurrence of retroflex stops where Standard Gujarati has dentals [t̪ t̪h d̪ d̪h]. We demonstrate the considerable amount of such “retroflex boosting” in the Cape Town variety. We provide a detailed and replicable methodology from variationist sociolinguistics for studying this boosting that we believe illuminates the study of its occurrence in modern dialects in Gujarat.

LncRNA XIST regulates atherosclerosis progression in ox-LDL-induced HUVECs
Authors: Gao Hongmei , Guo Zhaohui
Published: January 2021

Long noncoding RNAs (lncRNAs) have been verified as vital regulators in human disease, including atherosclerosis. However, the precise role of X-inactive-specific transcript (XIST) in atherosclerosis remains unclear. The proliferation and apoptosis of human umbilical vein endothelial cells (HUVECs) exposed to low-density lipoprotein (ox-LDL) were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazol-3-ium bromide, and flow cytometry assays, correspondingly. The western blot assay was used to quantify protein expression. Lactate dehydrogenase activity and the concentrations of inflammatory factors were measured by matched kits. The real-time quantitative polymerase chain reaction (qPCR) was used to determine α-smooth muscle actin, smooth muscle protein 22-α, XIST, miR-98-5p, and pregnancy-associated plasma protein A (PAPPA) levels in HUVECs. The relationship among XIST, miR-98-5p, and PAPPA was analyzed by dual-luciferase reporter, RNA immunoprecipitation, and RNA pull-down assays. We found ox-LDL repressed proliferation and induced inflammation and apoptosis in HUVECs. Loss-of-functional experiment suggested that the downregulation of XIST overturned the ox-LDL-induced effects on HUVECs. Additionally, overexpression of miR-98-5p-induced effects on ox-LDL-stimulated HUVECs was abolished by upregulation of XIST. However, silencing of miR-98-5p strengthened the ox-LDL-induced effects on HUVECs by increasing expression of PAPPA. Mechanistically, XIST could regulate PAPPA expression in ox-LDL-induced HUVECs by sponging miR-98-5p, providing understanding for atherosclerosis.

Uranyl oxalate species in high ionic strength environments: stability constants for aqueous and solid uranyl oxalate complexes
Authors: Xiong Yongliang , Wang Yifeng
Published: January 2021

Uranyl ion, UO2
2+, and its aqueous complexes with organic and inorganic ligands can be the dominant species for uranium transport on the Earth surface or in a nuclear waste disposal system if an oxidizing condition is present. As an important biodegradation product, oxalate, C2O4
2−, is ubiquitous in natural environments and is known for its ability to complex with the uranyl ion. Oxalate can also form solid phases with uranyl ion in certain environments thus limiting uranium migration. Therefore, the determination of stability constants for aqueous and solid uranyl oxalate complexes is important not only to the understanding of uranium mobility in natural environments, but also to the performance assessment of nuclear waste disposal. Here we developed a thermodynamic model for the UO2
2+–Na+–H+–Cl––ClO4
––C2O4
2––NO3
––H2O system to ionic strength up to ∼11 mol•kg−1. We constrained the stability constants for UO2C2O4(aq) and UO2(C2O4)2
2− at infinite dilution based on our evaluation of the literature data over a wide range of ionic strengths up to ∼11 mol•kg−1. We also obtained the solubility constants at infinite dilution for solid uranyl oxalates, UO2C2O4•3H2O, based on the solubility data over a wide range of ionic strengths. The developed model will enable for the accurate stability assessment of oxalate complexes affecting uranium mobility under a wide range of conditions including those in deep geological repositories.

Accurate control of centrosome number is essential for proper chromosome segregation, and it is well established that centrosome abnormalities can trigger a p53‐dependent cell cycle arrest. Two new studies published in The EMBO Journal demonstrate how PIDD1 is recruited to centrosomes and that the localization of PIDD1 to distal appendages of centrosomes is required for PIDDosome activation at clustered supernumerary centrosomes.
La atenuante de reparación del daño como instrumento de la justicia restaurativa en la delincuencia socioeconómica
Authors: Cuenca Garcia Mª José
Published: January 2021

Debe saludarse como especialmente atinente la objetivación de la atenuante que tiene lugar con la aprobación del Código penal de 1995, por la que se destierra el requisito del arrepentimiento espontáneo, y se facilita su aplicación al reo, con independencia de cuál sean los motivos de su actuación. La contrapartida de esa objetivación radica en que la búsqueda a toda costa de la efectiva reparación del daño de la víctima podría provocar fricciones tanto con el ideal de la justicia restaurativa, como con los fines del Derecho penal.

Published: January 2021

The notion of quasiary relation which can be considered generalization of the notion of traditional n-ary relation is proposed. A number of algebras of quasiary relations is built and investigated. Alongside with conventional operations of union, intersection, and complement, special nominative operations of renomi-nation and quantification are defined for quasiary relations. The isomorphism between the algebra of quasiary relations and the first-order algebra of total single-valued quasiary predicates is proved. Al-gebras of bi-quasiary relations defined over sets of pairs of quasiary relations are built. The isomorphism between algebras of bi-quasiary relations and alge-bras of quasiary predicates is proved. The following subclasses of algebras of bi-quasiary relations are specified: alge-bras of partial single-valued (functional), total, total many-valued bi-quasiary relations. For all defined subclasses their counterparts of the classes of algebras of quasiary predicates are described. Also subalgebras of the algebra of bi-quasiary relations induced by upward closedness and downward closedness are investigated.

Authors: Garanina Zhanna G. , Andronova Natalia V.
Published: January 2021

Introduction. The article analyzes the problem of professional self-awareness, and the influence of this phenomenon on the process of personal and professional self-development of students.

A theoretical study of this problem has shown that professional self-awareness is one of the most important prerequisites for the self-development and self-improvement of university students. Materials and Methods. The article presents the results of an empirical study of the characteristics of self-awareness and self-development of students of the Mordovian State University. A set of methods was used: questionnaire “Ability for self-development” I. V. Zvereva, methodology “Readiness for self-knowledge and self-development” T. A. Ratanova, N. F. Shlyakhta, test “Determination of the level of development of reflexivity” by A. V. Karpov, “Questionnaire of self-attitude” by V. V. Stolin, S. R. Pantileev, methods of researching self-assessment by S. A. Budassi, test “Assessment of self-control in communication” by M. Snyder, questionnaire “The style of self-regulation of students’ behavior” by V. I. Morosanova. Results. Statistically significant correlations between the reflexive, affective and regulatory components of students’ self-awareness and the level of their personal and professional self-development were revealed. It has been found that a high level of development of students’ reflective qualities is associated with their desire for self-knowledge. The connection between self-regulation and readiness for self-knowledge and self-development determines the ability of students to carry out systematic and purposeful work on themselves. It is shown that students with high and above average levels of self-development are aware of the changes taking place in the structure of their personality in the process of vocational training. These students are characterized by higher indicators of reflexivity, self-attitude and self-esteem compared to students with low and below average levels of self-development. Discussion and Conclusion. The results obtained confirm the assumption that personal and professional self-development is conditioned by the students’ ability to reflect and realize their personal and professional qualities.

Тим паче повноцінні тваринні білки значно переважають рослинні за біологічною цінністю, краще збалансовані за амінокислотним складом, є добрими емульгаторами, дозволяють переробляти малоцінну жировмісну сировину, покращують консистенцію і пластичність фаршу, підвищують органолептичні властивості готових виробів, збільшують вихід, дозволяють суттєво знизити собівартість продукту. Аналіз останніх досліджень і публікацій свідчить про можливість використання білків м'яса птиці з різних анатомічних частин як гарного структуроутворювача та білкового наповнювача для ковбасного виробництва. Показані композиції, які були створені шляхом компонування тваринного і рослинного білку. Встановлена раціональна масова частка внесення добавки у співвідношенні 80:20 рослинного і тваринного білку відповідно, що дозволяє переробляти малоцінну сировину, покращує консистенцію, пластичність (в’язкість) фаршу, сприяє поліпшенню органолептичних властивостей готових виробів, збільшують вихід, дозволяють суттєво знизити собівартість продукту. Наведено результати впливу даних добавок на функціонально-технологічні властивості та органолептичні показники м'ясних виробів. Показано, що створення композицій шляхом компонування рослинного та тваринного білку у співвідношенні 80:20 має найкращу розчинність та водоутримуючу здатність. Для підтримання сталого pH середовища добавки (створенної композиції) використовували буферні розчини з рН 4,1 та рН 6,55.  Розглянуто питання практичного використання білків рослинного і тваринного походження у технологіях виробництва ковбасних виробів із м'яса птиці.
Three Unpublished Byzantine Lead Seals from Western Asia Minor (With an Appendix on an Amulet from Izmir)
Authors: Laflı Ergün , Buora Maurizio
Published: January 2021

This paper presents three formerly unpublished Byzantine lead seals and an amulet that were examined in the archaeological museum of Izmir (nos. 1, 3 and figs. 5a–b) and Akhisar (no. 2) in western Turkey. They date from the 7th to the 13th century AD. The seal of a Manuel apo hypaton (no. 1) reveals the relations between the court of Constantinople and the city of Smyrna in the 7th century AD. Another one of Ioannes hypatos spatharios (no. 2) comes from Akhisar (8th century AD). No. 3 is dated to the 11th and 12th centuries AD. A lead amulet at the appendix part (figs. 5a–b), which perhaps originates from the Early Byzantine period, bears the name of Sabaṓth.
Rights over “The Property of Another” (Iura in re aliena) in Byzantine and Mediaeval Serbian Law
Authors: Šarkić Srđan
Published: January 2021

In some cases, when a person owned property, his rights over such property might be limited. The most important rights over another’s property, mentioned by Byzantine law and accepted in mediaeval Serbian legal sources are servitudes, pledge and emphyteusis. The rules on servitudes (δουλεία – rabota) penetrated in Serbian law at the beginning of 13th century, when Saint Sabba (Свети Сава) incorporated in his “Nomokanon” the whole Byzantine “Procheiron”. Its chapter XXXVIII, under the title “On novelties” (Περὶ καινοτομιῶν), contains different provisions, concerning the servitudes, mixed with administrative rules on building the new houses. That was the reason why Serbian translators of “Procheiron” entitled this chapter as “On building of new houses, reconstruction of the old and other things”. While the chapter XXXVIII of “Procheiron” contains 64 provisions, Matheas Blastares took in his “Syntagma” only 18, and created a short Chapter K-3 under the same title “On novelties” (“O novotvorenxhь” in Serbian translation). It contains, beside different decrees and prohibitions by administrative authorities, some urban servitudes, that could be changed by special agreements (συμφώνον – sьglasi«). Byzantine legal miscellanies always put together the rules on pledge in the same chapter with the provisions on loan, although modern legal science treats pledge as a part of the law of property and loan as a real contract and the part of the law of obligation. The chapter X of “Ecloga” has a title “On literal and unliteral loans and for them given pledges”; the chapter XVI of “Procheiron” is known under the title “On loan and pledge” and the chapter XXVIII of “Epanagoge” entitled “On loans and pledges”. For this reason, Matheas Blastares included the chapter Δ-2 under the title “On lenders, and loan, and pledges” in his “Syntagma”. Among Serbian legal sources, pledge was mentioned only in a few documents: these are so called “Justinian’s Law” (art. 26 and 27); King Milutin’s chrysobull, granted to the Hilandar’s pyrgos in Chrousija; King Dušan’s chrysobull, giving the church of Most Holy Virgin in Lipljan to the Hilandar’s pyrgos in Chrousija; and Dušan’s “Law Code” (art. 90). The chapter XV of the “Procheiron” has the title “On emphyteusis” and contains six provisions, speaking on emphyteusis of Church estates. Matheas Blastares introduced a short Chapter E-8, entitled “On emphyteusis” (“O nasa`denîi” in Serbian translation), in his “Syntagma”. Its chapter represents an interpretation of Justinian’s Novella CXX, chapters 2 and 8. In Serbian legal sources we can not find any information on emphyteusis.
Persian Immigrants in the Armed Forces of Early Byzantium
Authors: Nazarov Andrey
Published: January 2021

Introduction. The article is devoted to Persians who served in the Early Byzantine armed forces. Even during the Principate period, alae and cohortes which were originally recruited from Parthians were part of the Roman imperial army. Units from Persian defectors and prisoners were also created from the 4th to the 6th century.

Methods. Using tools of the positivist methodology makes it possible to provide a critical analysis of information from the sources. At the same time, the prosopographical method allows to study mechanisms of integration of immigrants from neighboring realms into the Early Byzantine society using examples of individual fates.

Analysis. According to “Notitia Dignitatum”, a significant part of military units of Persian origin served in eastern provinces of the empire. It is also known that cavalry vexillationes which consisted of immigrants from Iran were included in mobile armies. Some numeri with Persian prisoners were transferred to Italy in the 6th century. These units consisted mainly of heavily armed horsemen who were famous for eastern neighbors of Rome and Byzantium. In the framework of the presented article, the author refers to individual personalities who held commanding posts in the imperial armed forces. It is important to note that among them there were representatives of the Sasanian family. Ormizdas, the son of Hormizd II, Kavad, the grandson of Kavad I, and Khosrow II sought to find salvation from Iranian strifes at the court of the emperors. These individuals were considered as completely loyal to Byzantium candidates for the Shahanshah’s throne. However, only Khosrow II managed to return victorious to Iran in 591 with the support of eastern Roman emperor Maurice.

Results. The author concludes that military service was the main channel of integration into the society of the empire for Persian immigrants as well as other foreigners in the Late Antique period.
Material Culture of Byzantine Sugdeja in the 12th – Early 13th Centuries (To the Question of Chronological Indicators)
Authors: Maiko Vadim , Teslenko Irina
Published: January 2021

Introduction. The focus of this study is on the material culture of one of the major cities of south-eastern Taurika Sugdeja in the 12th and early 13th centuries, as well as archaeological sources that allow to highlight stratified archaeological complexes and horizons of that time. Special attention is paid to the justification of chronological indicators presented by household objects, decorations, objects of Christian cult and imported red clay glazed ceramics. The latter, based on modern chronological developments and the archaeological situation, is the most important indicator. It is common to combine this pottery into a group of Middle Byzantine Production (MBP).

Methods. The standard methods, which are usually involved for the study of archaeological materials, are used in the work: stratigraphic, typological, and comparative.

Analysis. The materials from decades of excavation in Sudak, which are stored in archives and museum repositories now, have been studied again. As a result, 5 sites with layers of the 12th – early / first half of the 13th centuries have been located in the different part of the medieval site, including the port area, as well as more than two dozen finds of the MBP were attributed.

Results. The newly obtained data allowed us to conclude that Sugdeja occupied a rather large area during the studied period and the city continued to maintain contacts with the Central Byzantine lands during all this time. Moreover, the findings of different stylistic and chronological types of ceramics indicate the presence of such contacts both during the reign of the Komnenoi and Angeloi, and after the conquest of Constantinople by the Latins in 1204.
O ódio na cultura e na clínica psicanalítica contemporâneas
Authors: Winograd Monah , Natale Rony
Published: January 2021

Neste artigo procuramos demonstrar como a agressividade foi considerada pela psicanálise desde os primeiros ensaios freudianos até a releitura de Lacan que, partindo de uma agressividade do sujeito dirigida ao outro semelhante, avança rumo à concepção do ódio ao Outro. Enfatizamos, quanto a isso, o último momento de seu ensino, no qual sobressai o conceito de Real, crucial para compreendermos a gênese do ódio na constituição subjetiva. Mostramos como tal referência passa a influenciar a maneira como a cultura - e sobretudo a clínica - são consideradas, convocando o sujeito a se haver com o Real da existência.
Moving beyond psychiatric diagnosis and the medical framework towards social recovery: an interview with Jim van Os
Authors: Zorzanelli Rafaela , Banzato Claudio E. M.
Published: January 2021

There is a growing realization in the field of psychiatry that we are unable to free ourselves of the constraints imposed by our concepts, as well as to move beyond them. Thus, the field demands not only more robust empirical evidence but also a more sophisticated conceptual framework, which would allow for critical and innovative thinking to conceive and to build better models of mental health care. In this spirit, we present a very thought-provoking interview with Dutch psychiatrist Jim van Os, encompassing biographical issues from his academic background as well as his ideas on recovery and the Dutch experience of the recovery colleges as a “shadow mental health system” in the Netherlands. Adopting a critical stance on psychiatric diagnosis and the validity of group-level comparisons in evidence-based psychiatry, and in line with the ideals of the recovery movement, van Os points out that the process of healing should surpass symptom reduction. For him, it should take into account the long-term process of developing resilience, learning to deal with suffering through interactions with other people, building up new perspectives, goals, and existential purposes. In other words, he emphasizes the idea of social recovery and favors the thought that mental health professionals should try to “help people to relate better to their mental variation and offer them ways of doing that differently.”
Trauma e testemunho em Ferenczi: uma análise de Vozes de Tchernóbil de Svetlana Aleksiévith
Authors: Baracat Juliana , Abrão Jorge Luis Ferreira , Martínez Viviana Carola Velasco
Published: January 2021

O artigo aborda as noções de trauma e testemunho elaborados por Sándor Ferenczi e os articula com o livro Svetlana Aleksiévitch acerca do desastre nuclear de Tchernóbil. Nosso objetivo foi demonstrar a validade das observações de Ferenczi em relação a um trauma coletivo, organizado em torno de três eixos: a dissimetria relacional, o processo de desmentido e o narcisismo ferido. Através da leitura do livro pode-se compreender como a escritora teve seu papel aproximado daquele designado por Ferenczi.
O ato fotográfico a partir do olhar
Authors: Anjos Patrick Werner dos , Ferreira Nadiá Paulo
Published: January 2021

O nosso objetivo é articular a fotografia com a diferença que Jacques Lacan apresenta, no Seminário 11. Os quatros conceitos fundamentais da psicanálise, entre o olho, o olhar e ser olhado. Dessa articulação nascem as questões: Até que ponto podemos confiar no caráter de evidência fidedigna da realidade na fotografia? Em um mundo dominado pelas imagens, qual o efeito que a fotografia provoca em nós como espectadores?
