Band structure tuning of g-C3N4 via sulfur doping for broadband near-infrared ultrafast photonic applications
Authors: Dong Li , Chu Hongwei , Xu Shiping , Li Ying , Zhao Shengzhi , Li Dechun
Published: November 2021

Graphitic carbon nitride (g-C3N4) featuring a stable heptazine ring structure and high polymerization degree, was indexed as a high thermochemical stability material, attracting rising research enthusiasm for diverse applications. However, the poor near-infrared (NIR) optical absorption and resulting limited NIR applications were pronounced for g-C3N4 due to its large bandgap of 2.7 eV. In the present work, sulfur-doping was manifested by first-principles calculations to introduce impurity level and result in anisotropic spin splitting in g-C3N4 for enhancing broadband nonlinear optical characteristics in NIR regime. The modified sulfur-doped g-C3N4 (S-C3N4) exhibited the maximum effective nonlinear absorption coefficient to be −0.82 cm/GW. Pulse duration within hundred nanoseconds was realized with high modulation stability employing S-C3N4 as saturable absorber in Q-switching operations. Moreover, broadband ultrafast photonics properties were successfully demonstrated in constructed ytterbium-doped and erbium-doped fiber lasers, generating highly stable dissipative soliton and traditional soliton mode-locking pulses. The presented S-C3N4 nanomaterial with remarkable nonlinear optical performances might explicitly boost the development and application of g-C3N4 materials in advanced optoelectronic and ultrafast photonic devices.

Approaches to the study of address in pluricentric languages: methodological reflections
Authors: Schüpbach Doris , Hajek John , Kretzenbacher Heinz L. , Norrby Catrin
Published: November 2021

While research on pluricentricity has traditionally focused on phonological, lexical and grammatical variation across national varieties, pluricentric languages also provide a rich laboratory for the exploration of pragmatic variation, and potentially new insights into the complexities of both pragmatics and pluricentricity. Pluricentric pragmatics remains a developing field and determining appropriate methodologies and strategies for data collection remains open to evaluation and assessment. Methodological considerations pertaining to address research in pluricentric languages are made from a range of perspectives, which are typically interconnected and will depend on the intended research focus. In this contribution we present a critical reflection on methodological aspects of pragmatic research, based on our own experiences investigating address in several pluricentric languages (in particular German and English). After a brief overview of the pluricentric languages considered and their address systems we provide an outline of the research projects reviewed. We then discuss in detail issues regarding data types and data collection (in particular questionnaires, interviews, focus groups and various online data) and consider further methodological aspects such as the choice of research framework, context and type of address investigated, quantitative and/or qualitative approaches taken and whether the research focus is on actual use, reported use and/or perceptions. We conclude with some suggestions for further research directions.
Croatia’s Knowledge Production on Kosovo around 1989
Authors: Janković Branimir
Published: November 2021

In socialist Yugoslavia in 1989 the extremely sensitive matter of Kosovo had an ambiguous effect on the League of Communists of Croatia, which was then still caught in the so-called “Croatian silence”. It did however provoke much turbulence in the Croatian media, which made pointed comments on the larger Yugoslav crisis, on the situation in Kosovo, and on the politics of Serbian president Slobodan Milošević. An intense dynamic could be also found in the field of knowledge production which encompassed scholars, historians, and intellectuals. Who produced knowledge about Kosovo? What were their political and intellectual agendas? How did they intervene in the dominant discourses and media coverage, what debates and reactions did they spark? Within the frames of the history of knowledge, the history of books and intellectual history, the author here assesses the works on Kosovo of a number of Croatian and Yugoslav intellectuals, chiefly Darko Hudelist and Branko Horvat.

The antiplasmodium assay-guided investigation of the roots, stem bark, and leaves of Persea americana Mill. led to the isolation of a new fatty alcohol, perseatriol (1), along with six known compounds (2–7). Their structures were elucidated based on the analysis of their NMR and MS data. All crude extracts and fractions exhibited good antiplasmodial activity on Plasmoduim falciparum 3D7 with IC50 values ranging from 0.76 to 10.5 μg/mL; they also displayed cytotoxicity against HeLa cells with low selectivity indexes (SIs). A preliminary Plasmodium lactate dehydrogenase (pLDH) assay was also performed on the isolated compounds. 9,9′-Di-O-feruloyl-5,5′-dimethoxysecoisolariciresinol (4) turned out to be non-toxic and displayed the best activities on P. falciparum with an IC50 value of 0.05 μM, comparable to the reference drug chloroquine with an IC50 value of 0.03 μM. Furthermore, besides compound 4, this work reports the first isolation of lutein (2) and scopoletin (3) from P. americana. The crude extracts of roots, stem bark, and leaves of P. americana, their fractions and compounds completely suppressed the growth of P. falciparum. The observed activity supports the use of P. americana in folk medicine for the treatment of malaria.
Efecto del consumo de energía renovable en las emisiones de gases de efecto invernadero en países con ingresos bajos y altos
Authors: Hernández Pérez Jonathan
Published: November 2021

Las actividades humanas están aumentando las emisiones de gases de efecto invernadero (GEI) en el mundo, por lo que es necesario buscar alternativas para reducirlas. El presente trabajo tiene como objetivo determinar el efecto que tiene el uso de energías renovables y el crecimiento económico sobre las emisiones de GEI (de 1990 a 2012) en dos grupos de países, uno con ingreso per cápita bajo y otro con ingreso per cápita alto según la clasificación del Banco Mundial (BM), mediante un análisis de datos panel. Asimismo, se realizó una regresión por mínimos cuadrados ordinarios (MCO) del modelo para México y Alemania. Los resultados del análisis indican que un incremento del 1% en el consumo de energías renovables reducen las emisiones de gases de efecto invernadero 0.0294% en el grupo de países con ingresos altos y 0.0171% en el grupo de países con ingresos bajos. Además, cuando aumenta el 1% en el ingreso per cápita, aumentan las emisiones de gases de efecto invernadero en 3.5935% en los países con ingresos altos y 11.6974% en los países con ingreso bajos. De la misma manera, con el incremento del 1% en el consumo de energía renovable, las emisiones de GEI se reducen en 31 219.9 kt de CO2 en México y 18 160.0 kt de CO2 en Alemania. En conclusión, el consumo de energías renovables contribuye a mejorar la calidad ambiental al reducir el consumo de otras fuentes de energías no renovables.
Interactions among Economic Ideas, Policies and Experience - The Establishment of Inflation Targeting in Canada, 1991-2001
Authors: Laidler David
Published: November 2021

In Canada, targeting the inflation rate was intended as a temporary measure during a transition to price-level stability, but became a well-established monetary policy regime in its own right. This paper analyses the role of the interaction of economic ideas with the experience generated by their application to policy in bringing about this outcome. In the following account, changing beliefs about the stability or otherwise of ongoing inflation, the capacity of a flexible exchange rate to create a vicious circle of depreciation and rising domestic prices, are emphasised, while ideas about the natural unemployment rate and money growth in influencing economic outcomes are also discussed. Today’s standard theoretical approach to modelling inflation targeting arrived on the scene only as the Canadian regime was becoming well established.
Another Look at Devaluation and the Trade Balance in China
Authors: McGee Ethan , Upadhyaya Kamal P , Bhandari Rabindra N
Published: November 2021

This paper estimates the effect of Chinese Yuan devaluation on the trade balance of China.  For that a regression equation is developed in which domestic income, foreign income, domestic money supply, foreign money supply and real effective exchange rate are used as explanatory variable with trade balance as the dependent variable. In order to test the J-curve phenomenon the lagged values of exchange rata are also included.  Quarterly time series data from 1999 to 2016 are used.  Before estimating the model the time series properties of the data are diagnosed and an error correction model is developed and estimated.  The estimated results show that the contemporaneous effect of devaluation is positive, but the total effect is insignificant.  A J-curve pattern of adjustment of the trade balance is also detected.
A Pure Bureaucratic-Entrepreneurial Theory of Deposit Insurance Adoption
Authors: Chu Kam Hon
Published: November 2021

Based on Becker, Kane, Niskanen, and Peltzman’s ideas, we develop a model to explain why deposit insurance is adopted even though policymakers are aware of its pitfalls in both theory and practice. In our model, the regulator acts as both a bureaucrat and an entrepreneur to maximize his self-interest through administering a deposit insurance scheme. The theory postulates that adoption of deposit insurance is more likely under the following conditions: the scheme is (i) publicly administered and (ii) privately funded, with (iii) non-risk rated insurance premium and (iv) compulsory membership; and there is (v) a larger deposit market with (vi) at least two groups of banks (good vs. bad), (vii) lower government ownership of banks, and (viii) higher economic freedom, such that one group exerts its political influence and gains from deposit insurance. Empirically our theory is supported by the stylized facts, cross-country binary-choice regression results and a case study of Canada.
Can Dynamic Panel Data Explain the Finance-Growth Link? An Empirical Likelihood Approach
Authors: Oguzoglu Umut , Stengos Thanasis
Published: November 2021

The short run effect of the financial intermediary development on economic growth is analyzed using an unbalanced panel of 77 countries covering 35 years. Empirical Likelihood (EL) estimation is used and compared to more conventional GMM methods that weight moment conditions equally over the sample. However, if a part of the data is associated with only weak instruments, GMM estimators are subject to considerable small sample bias. EL appropriately re-weights the moment restrictions to deal with that problem. Using EL, we obtain more robust estimates of the effect of financial intermediation on economic growth than GMM.
The Effect of Emissions on U.S. State Total Factor Productivity Growth
Authors: Empora Neophyta , Mamuneas Theofanis
Published: November 2021

This paper investigates the effect of sulphur dioxide (SO2) and nitrogen oxide (NOx) emissions on the Total Factor Productivity (TFP) growth among 48 contiguous U.S. states, for the period 1965-2002. The relationship between TFP growth and emissions is examined using nonparametric econometric techniques that allow for the estimation of the elasticity of pollution for each state and each period and to account for possible nonlinearities in the data. The results indicate that both pollutants positively affect TFP growth. Moreover this effect is nonlinear. The average output elasticity for all states is 0.005 for SO2 and 0.04 for NOx emissions.

Asymmetry and Lilien’s Sectoral Shifts Hypothesis: A Quantile Regression Approach
Authors: Panagiotidis Theodore , Pelloni Gianluigi
Published: November 2021

This study revisits Lilien’s sectoral shifts hypothesis for the US. We employ quantile regression estimation in order to investigate the asymmetric nature of the relationship between sectoral employment and unemployment. Significant asymmetries emerge. Lilien’s dispersion index is significant only for relatively high levels of unemployment and becomes insignificant for lower levels suggesting that reallocation affects unemployment only when the latter is relative high. More job reallocation is associated with higher unemployment.
Business Cycle Dynamics of Economic Growth in the OECD Countries: Evidence from Markov-Switching Model
Authors: Singh Tarlok
Published: November 2021

This study estimates the Markov-switching model and examines the Keynesian business cycle dynamics ofeconomic growth for a comprehensive set of eight OECD countries. The estimated duration of regime one is (i)shorter for Denmark, Sweden and Switzerland, (ii) moderate for France and (iii) longer for Belgium, Spain andthe U.S. The persistence of regime two is observed to be (i) shorter for Belgium, Canada, Spain, Sweden andthe U.S., (ii) moderate for Denmark and France, and (iii) longer for Switzerland. The stylized evidence for thepersistence of a given state has important implications for Keynesian policy activism and the formulation ofmacroeconomic stabilization policies. The monetary and fiscal policies are used to reduce the amplitudes andtime-durations of the economic growth cycles and, thus, stabilise the output around its long-run natural ratelevel and the inflation around its target level. The short-run downward rigidities in prices in the goods marketsand in nominal wages in the factor markets tend to impinge upon the clearance of markets and the accelerationof economic growth during recessions, thereby leading to the pathologically longer durations of lower regimes.While the longer durations of upper regimes support the sustainability of the expansionary economic policies,the adequate precautions need to be taken for the inflationary implications of these policies.
Role of Focus and Managerial Ownership in Financial Performance of REITs: An Empirical Examination
Authors: Al-Shimmiri Turki Badi , Bhuyan Rafiqul , Sbeiti Wafaa
Published: November 2021

In this research, we examine the effect of focus and managerial ownership on the financial performance of REITs. Results demonstrate a positive relationship between focus and financial performance in this sector that are consistent with the findings in current literature. Impact of managerial ownership, however, seems weak on REITs performance. Our findings provide direct support for the convergence-of-interests hypothesis. We also examine the curvilinear relationship between firm performance and managerial ownership already documented in the literature. Our results show that this relation is not supported in the REITs sector. Our results do not support the entrenchment hypothesis.  In addition, when agency conflicts drive the increase in focus strategy is investigated, we find that the agency conflict explanation for increase in focus strategy is warranted.
About the Calculation of the Compliance Value and its Practical Relevance
Authors: Westhausen Hans-Ulrich
Published: November 2021

Corporate investment in compliance in general and compliance management systems (CMS) in particular, follow the cardinal management obligation to always obey the law (so-called “management duty to legality”). But does the compliance function as any other corporate investment really add value favoring all shareholders? The socially desired answer should be probably “yes”, but the business reality shows a different picture: the measurement of the compliance value is a “blind spot” in the scientific theory and research as well as in the corporate practice. This paper analyzes reasons for that “blind spot” and explores the systematization of the compliance value drivers setting up a practical model that monetarizes these effects as well as calculating the added value and ROI of compliance. The author concludes that this quantification is particularly relevant to practice, as the compliance function must be able to measure the quantified impact(s) of the compliance function in order to demonstrate its value to management, shareholders, as well as all interested parties, and to justify and strengthen its role increasing the effectiveness of the CMS as part of the company’s “second line of defense”.
On the History of Old Believer in Lithuania in 19th Century: Rimkai Old Believer Church Assembly in 1856 and its Resolutions
Authors: Morozova Nadežda
Published: November 2021

The history of Old Believers in Lithuania in the 19th century is insufficiently studied. Well, we know the main centers, events and names of the most important figures, the key moments in the history of the Old Believer society are identified. But there are any generalizing monographs in this field and now the main task is to accumulate empirical material and try to put them in a future common historical narrative.

The Old Believer community of Rimkai is one of the oldest in the central part of present-day Lithuania. In 1856 an Old Believers’ church assembly was held in the village of Rimkai. This assembly has so far been unknown in historiography, so this is the first time information about the meeting is being introduced into scientific circulation. The resolutions of the assembly are preserved in the only manuscript, which i s now held at the Russian State Library as part of E. V. Barsov’s collection no. 1025. The resolutions consist of 33 articles discussing the Old Believers’ iconolatry as well as regulation of ritual and everyday norms of behaviour applicable to both church leaders and ordinary parishioners. The documents were signed by 13 Old Believers’ spiritual fathers and monks from Lithuania and East Prussia.

This study contains a diplomatic edition of Rimkai resolutions too. The text of the document is supplemented by historical commentary and source analysis.
Mathematical Model of Determination and Analysis of Heat Exchange in Elements of Digital Technology Devices
Authors:   Lviv Polytechnic National University, Havrysh V.I.
Published: November 2021

A mathematical model of heat exchange analysis between an isotropic two-layer plate heated by a point heat source concentrated on the conjugation surfaces of layers and the environment has been developed. To do this, using the theory of generalized functions, the coefficient of thermal conductivity of the materials of the plate layers is shown as a whole for the whole system. Given this, instead of two equations of thermal conductivity for each of the plate layers and the conditions of ideal thermal contact, one equation of thermal conductivity in generalized derivatives with singular coefficients is obtained between them. To solve the boundary value problem of thermal conductivity containing this equation and boundary conditions on the boundary surfaces of the plate, the integral Fourier transform was used and as a result an analytical solution of the problem in images was obtained. An inverse integral Fourier transform was applied to this solution, which made it possible to obtain the final analytical solution of the original problem. The obtained analytical solution is presented in the form of an improper convergent integral. According to Simpson's method, numerical values of this integral are obtained with a certain accuracy for given values of layer thickness, spatial coordinates, specific power of a point heat source, thermal conductivity of structural materials of the plate and heat transfer coefficient from the boundary surfaces of the plate. The material of the first layer of the plate is copper, and the second is aluminum. Computational programs have been developed to determine the numerical values of temperature in the given structure, as well as to analyze the heat exchange between the plate and the environment due to different temperature regimes due to heating the plate by a point heat source concentrated on the conjugation surfaces. Using these programs, graphs are shown that show the behavior of curves constructed using numerical values of the temperature distribution depending on the spatial coordinates. The obtained numerical values of temperature indicate the correspondence of the developed mathematical model of heat exchange analysis between a two-layer plate with a point heat source focused on the conjugation surfaces of the layersand the environment, the real physical process.

Published: November 2021

Gene stacking is the process of addition of two or more gene of interest into a single plant. The combination or stacking of different traits or genes in plants is rapidly gaining popularity in biotech crop production. The new evolved trait is known as stacked trait and the crop is known as biotech stacked or simply stacked. This can be accomplished in many ways, one of which is gene pyramiding. Biotech stacks give crops a larger genetic and agronomic boost, allowing them to perform better in challenging farming situations. Biotech stacks are designed to increase productivity by overcoming biotic and abiotic challenges like as insect pests, diseases, weeds, and environmental stress. This review will explain about the gene stacking principle, the need for biotech stacking, and the many gene stacking methods.
El taller literario como estrategia pedagógica en el aula.

Published: November 2021

El tema del presente artículo aborda al taller literario como dispositivo didáctico en la enseñanza de la literatura apoyado desde soportes teóricos y metodológicos suficientes que sustentan claramente su desarrollo en el aula. Se encuentran hallazgos en los que demuestran ciertas ambigüedades con respecto a las habilidades que fortalece el taller literario, así como el enfoque casi exclusivo a la lectura, suprimiendo en cierta medida los procesos de escritura creativa en relación con un marco metodológico implícito que debido a su informalidad no puede aportar al desarrollo del taller como dispositivo pedagógico organizado. Son múltiples las voces que se han pronunciado sobre el taller literario: algunos desde su experiencia en el desarrollo de estos espacios para la creación literaria; otros desde el taller de lectura literaria en ámbitos escolares formales; otros tantos, desde una mirada de la formación de escritores y el problema de la enseñabilidad de la literatura como carrera de formación profesional. Gianni Rodari (1973), Louise Rosenblatt (1978), Benigno Delmiro Coto (2001), y finalmente, Teresa Colomer (2001). Igualmente, otras propuestas como los talleres de escritura creativa de RELATA (2010), muestran formas de sistematización de la práctica artística literaria. Este trabajo dialoga desde perspectivas generando estrategias que unen al taller de creación literario y el taller pedagógico en el contexto de la Pedagogía de la Literatura.
A Comparative Investigation of the Mechanical Properties of Single and Bi Layer MoS2 Structures: Influences of Defect, Strain Rate and Temperature
Authors: ŞENTÜRK Ahmet Emin
Published: November 2021

In this paper, the mechanical properties of single and bi layer molybdenum disulfide (MoS2) structures are investigated using uniaxial tensile molecular dynamics (MD) simulation. According to the results of MD simulations, these structures show superior mechanical properties (failure strain, ultimate tensile strength and Young’s modulus) for various applications of nanodevice. The mechanical properties of single and bi layer MoS2 structures are studied at four different temperatures between 300 K and 900 K and different strain rates from 107 s-1 to 109 s-1. As temperature increases up to 900 K, the mechanical properties of single and bi layer MoS2 structures gradually decrease, due to the high temprerature’s weakening eﬀect. Also, changing of temperatures shows more effect on the bi layer MoS2 structure than single layer MoS2 structure. Furthermore, MD results show that the mechanical properties of single and bi layer MoS2 structures demonstrate increasing trend when the strain rate increases. Different strain rates indicate similar effects on the mechanical properties of single and bi layer MoS2 structures. On the other hand, the mechanical properties of these structures are adversely affected by structural defects. Accordingly, the influences of two different S atom types vacancy defect on the mechanical properties of single and bi layer MoS2 structures are examined. When the vacancy defect concentrations in MoS2 structures increase, the mechanical properties of these structures decrease significantly. In addition, S atom bi vacancy defects type exerts more effect on the mechanical properties of single and bi layer MoS2 structures than S atom single vacancy defect type do by increasing concentration. Additionally, vacancy defects indicate more influence on the bi layer MoS2 structure than single layer MoS2 structure. Finally, the results of this study make them excellent candidate for nano-mechanical systems.

Authors: KÜLAHCI Meryem Burcu , ÇITAK Sumru , ŞAHİN Zehra
Published: November 2021

The aim of this study was to determine the multiple antibiotic resistance profiles of Enterococcus spp. isolated from the fermented meat products consumed in Ankara, Turkey. A total of 134 Enterococcus spp. were isolated and identified from 80 fermented meat samples. The highest prevalence of enterococci in the fermented food samples was found in sucuk (a Turkish fermented sausage) samples (50%), followed by sausage (25.4%), pastirma (a Turkish dry-cured meat product) (18.6%), and salami, respectively. Of a total of 134 Enterococcus isolates, 110 (82.1%) were found to be resistant to one or more of the antibiotics tested. Although the highest resistance rate was seen against rifampicin (73.2%), streptomycin (36.5%) and erythromycin (20.2%), 28 (20.9%) of Enterococcus isolates were resistant to multiple antibiotics. The presence of multiple antibiotic resistant Enterococcus in foods of animal origin raises alarm because of the risk of carrying these bacteria to humans via the food chain.
Problems of the Criminal Prosecution of Persons Who Committed Actions Constitution Implication in a Crime
Authors: Gotchina Larisa , Dvorzhitskaya Marina
Published: November 2021

The paper discusses highly latent actions constituting implication in a crime. The goal of this study is to identify the problems of criminally prosecuting persons who committed actions constituting implication in a crime, to qualify them and to develop recommendations for their elimination. Formal legal and comparative legal methods were used to obtain and process results relevant for the research, the statistical
method was used to collect and analyze data on the examined crimes, and the sociolo­gical one — to conduct a survey of experts. An analysis of criminal cases made it possible to state that the problem of criminally prosecuting persons who committed actions constituting implication in a crime is connected with the problems of their qualification, and with widening the institute of implication through failure to report a crime; this action is included in the Criminal Code of the Russian Federation in connection with the topical issues of terrorism threat, a growing number of terrorist crimes and the necessity to protect the society from them. The authors believe that it is reasonable to recognize 16 years old as the minimum age of criminal responsibility for failure to report a crime. It is proven that the criminal character of implication in a crime could be based not only on the guilty verdict for the main case, but also on other procedural acts. It is concluded that implication in a socially dangerous act is possible for a person who does not possess the attribute of a subject of a crime due to his/her mental incompetence, and is also possible for a crime committed in complicity. It is stated that concealment of a crime is constituted by actions to conceal the event of the main crime, its traces, the objects obtained through criminal means, or the person who committed the main crime. It can be committed not only through physical, but also through intellectual actions. The authors suggest differentiating between criminal liability for the concealment of grave and especially grave crimes. The analysis of judicial investigation practice made it possible to identify typical models of qualifying actions constituting implication in a crime, as well as psychological, moral, criminological and criminal law features of a person who conceals a crime or fails to report it. Based on the authors’ position, a formulation of the decree of the Plenary Session of the Supreme Court of the Russian Federation «On some issues of implication in a crime» is suggested.
Making Wine Without Grapes: The Case for Quality Teaching With Limited Resources
Authors: Matope Jasmine
Published: November 2021

This article illustrates the significant role that creative, conscientious, dedicated, motivated, and committed teachers play in guiding, directing, and developing students' thinking, perspectives, and future lives. It highlights the importance of teacher agency in connecting learning to students' lives. It argues that good teachers can employ pedagogical practices that are not dependent on the availability of resources. It employs Pierre Bourdieu's theories of capital, field, and habitus to show how teachers can develop students' dispositions, consciousness, perceptions, perspectives, and lives. It also uses Nancy Fraser's theory of social justice to show how teachers can develop in working-class students, the essential knowledge, skills, and understandings that enable them to compete on a par with middle-class students. It uses life course theory to understand how the participants' schooling experiences, relationships, interconnectedness, and transitions influenced their thinking, doing, and lives. It employs a qualitative paradigm to explore five students' and one teacher's notions of how teaching and learning practices assisted the students to overcome the issue of inadequate resources. To locate the participants' perspectives and to analyse how their schooling experiences in the period 1968-1990 influenced their lives, the article uses the life history technique. The findings of the research stress that it is the inventiveness, competence, and attitude of the teacher that are the defining factors in the provision of quality education-not merely the availability of material resources.
Teachers' Experiences in the Implementation of the Life Skills CAPS for Learners With Severe Intellectual Disability
Authors: Rens Julialet , Louw Hannelle
Published: November 2021

This article focuses on a participatory process where the experiences of teachers regarding the implementation of the life skills curriculum and assessment policy statement (CAPS) for learners with severe intellectual disabilities (SID) in schools for learners with special educational needs were investigated. This curriculum for learners with SID has been developed to be more effective in meeting the needs of these learners. The curriculum ensures that learners can meet the requirements of the national CAPS used in ordinary public schools at a reduced depth and width, or at a more functional level, in accordance with their cognitive abilities. Although a descriptive mixed research method was applied in the study, this article reports on the qualitative part of the research. In the qualitative phase, collages and arts-based discussions with core project groups were used to generate data. Four schools, 13 core project groups, and 51 participants (teachers) were involved in the research. The transcribed data from the core project group discussions were analysed using thematic analysis, and the themes that emerged were discussed by the participants. Based on the results of these qualitative arts-based discussions, the findings were used to create opportunities for the teachers to talk and work together to jointly develop a training manual for beginner teachers and to form a learning environment that would permit rich inquiry-based dialogue among the teachers.
INTERVENCIÓN EN EL CENTRO PENITENCIARIO DE SEVILLA, CON LAS PERSONAS QUE PRESENTAN UNA PD: TMG Y ADICCIONES
Authors: Vicente Bernal Julian , Yague Concha , Chica Carmen , Vidal Francisco
Published: November 2021

Objetivos: El programa PAIEM (programa de atención integral al enfermo mental) está orientado a las personas que ingresan en Centro Penitenciario con un TMG o TP grave, siendo su objetivo la detección, estabilidad psíquica, intervención individualizada y posterior integración social, conscientes de la vulnerabilidad que presentan estas personas y lo que representa el entorno penitenciario. Material y métodos: El Equipo PAIEM, se encuentra integrado por distintos profesionales: psicólogo/a, educador/a, sanitario/a, trabajador/a social, coordinadora del programa, subdirector de tratamiento y otras entidades que directamente desarrollen su actividad laboral con estos colectivo. En la actualidad se encuentran incorporados al programa 35 pacientes (todos ellos de Sevilla y provincia), distribuidos por distintos módulos del Centro Penitenciario ( 16 módulos y 2 enfermerías). En función del grado de autonomía y estabilidad psíquica, se les clasifica en 3 niveles de mayor a menor funcionalidad y estabilidad. El 90% de los pacientes incorporados al programa PAIEM presentan un diagnóstico de Patología Dual, que dificulta el abordaje. La intervención pretende atender las necesidades de este colectivo, contando (en teoría) con las unidades de gestión clínica de salud mental que atienden, en ambiente normalizado, a estos pacientes, con el objetivo de facilitar la comunicación entre administraciones y una reincorporación progresiva, planificada y normalizada. Resultados y Conclusiones: Nuestra intervención es muy limitada y sesgada. La dispersión modular de los pacientes, puede ser valorada a efectos de integración, pero su abordaje se hace complicado. La comunicación y transmisión de información, como por ejemplo informes y tratamiento, con las Unidades de Gestión Clínica de Salud Mental es prácticamente inexistente, así como la ausencia de sanitario especializado. El tratamiento del paciente que ingresa en un Centro Penitenciario, para ser efectivo, ha de ser integral; con la implicación de todos los agentes que de una u otra forma participamos en su intervención.
Revitalising South African City Centres Through ICT
Authors: Das Dillip Kumar
Published: November 2021

The majority of South African city centres are in a state of degeneration and need revitalising. The factors that contributed to the degeneration and how the integration of information and communications technology (ICT) can be used to revitalise them were examined in three South African city centres. The research was grounded in place theory. A survey method, including the Delphi technique, followed by factor analysis, and ordinal regression modelling was used to collect and analyse data. The findings indicated that enhancing accessibility and safety, social and community involvement, human experience, built-up environment, and vibrancy were the five major components which needed reinforcing to revitalise the city centres. However, ICT-linked strategies, including networking the areas with free Wi-Fi hotspots, creating places in which to congregate, providing digital screens, and installing cameras and remote monitoring, are expected to attract people and to facilitate accessing real-time information about different events, marketing, branding, and creating a unique image. Also, the use of ICT will assist in reducing criminal activities and dispel the fear of crime. The combined effect is likely to encourage people and businesses to return the city centres, making these areas vibrant and accessible.
Public Space at the “Palm of a Hand”: Perceptions of Urban Projects Through Digital Media
Authors: Ioannou Byron , Kalnis Gregoris , Nicolaou Lora
Published: November 2021

This article examines the interactions between digital and social media as the contemporary incubators of place perceptions and the critical debate of environmental quality. Digital and social media may change the way people live but not the way they use physical spaces. This indirect reading of place acts in terms of perceptual understanding in a number of ways, but, most importantly, it becomes fundamental in the “construction” of the sense of place. This is because it impacts on the way information is associated with reality or a contract of the reality which is generated through its “interference” with our intellectual and emotive understanding of place. At the same time, the politics of a new “sociality” contains participations and exclusions. The article adopts comparative case study research as the methodological approach for investigating notions of how urban space is perceived through the case study of Eleftheria Square in Nicosia, a controversial urban regeneration project that generated an extensive debate through digital and social media in Cyprus during the last two decades. It is an attempt of a parallel decoding of (i) a more formal or directive view through digital newspapers’ survey and (ii) an informal view through a Facebook group content analysis. Through the case study, the inefficiencies and potentialities of the new media tools in informing the wider public are clear by providing at the same time evidence of their priorities, preferences, and fears. The article comes to two basic conclusions: (i) the perceptions of urban projects through digital media are not static but fluent and constantly updated, usually turning positive as projects are completed and experienced; and (ii) the interactive and synchronous nature of social media provides a more accurate and updated picture of the society’s changing perceptions of public space.

Echocardiographic findings in pulmonary immaturity in premature infants
Authors: Kudris I. V.
Published: November 2021

The main cause of morbidity in preterm and premature infants remains pulmonary pathology. Among the features of the bronchopulmonary structures of premature and immature preterm infants is a lag in the development of the arterial network from the venous one. Small and medium arteries have narrow lumen and thick muscle mass. When the lungs are unfolded, an obstacle is created for rapid blood flow in the small circle of circulation, which results in delayed unfolding of the alveoli.
Doppler ultrasound in urology

Published: November 2021

Due to the rapid development of new computer technologies and their rapid introduction into the field of medical technology the diagnostic capabilities of ultrasound have significantly enriched and expanded. A new trend appeared - ultrasound angiography based on color Doppler mapping (CDM), three-dimensional reconstruction of vessels, use of echocontrast enhancement of Doppler signal and "second harmonic" energy. The new method of vascular studies was based on the physical phenomenon discovered in 1842 by the Austrian scientist Doppler and named after him in the world literature.
