Introducing the Egypt Labor Market Panel Survey 2018
Authors: Krafft Caroline , Assaad Ragui , Rahman Khandker Wahedur
Published: September 2021

This paper introduces the 2018 wave of the Egypt Labor Market Panel Survey (ELMPS), previously fielded in 1998, 2006, and 2012. The ELMPS has already become the primary source of data for a large number of scholarly and policy studies on the labor market and human development issues in Egypt, and this new wave will further enhance its value as a critical data public good. This longitudinal survey is nationally representative, tracking both households and individuals over two decades. In this paper, we describe the key characteristics of the 2018 wave, including sampling, fielding, and questionnaire design. Changes in the collection of retrospective data starting in 2018 are discussed, and we demonstrate that they improved the data quality. We examine the patterns of attrition and present the construction of weights designed to correct for attrition, as well as to ensure that the sample remains nationally representative. We compare the ELMPS data with other Egyptian data sources, namely, the 2017 Census and various rounds of the Labor Force Survey (LFS). The data provide important new insights into Egypt's labor market, economy, and society.
Does Polish Post-Communist Cultural Burden Influence the Perception of Creative Identities?
Authors: Szostak Michał
Published: September 2021

Objective: Post-communist countries, affected by decades of one of the most repressive political systems, are perceived as a particular area of gaps in social capital. These gaps influence the whole spectrum of behaviors of individuals, groups, and society. Countries that changed their political system start a journey of external (economic, social) and internal (personal, interpersonal, group) changes. The post-communist burden determines human behavior, so leaders and managers should pay attention to these consequences. The research deals with the differences in perception of creative identities (a creator, artist, manager, entrepreneur, and leader) by Polish society compared to other countries without communist history.

Methodology: Quantitative research (n = 160) in the form of a survey among people from Poland and other countries. Verification of hypotheses by chisquare test of independence used (SPSS, MS Excel). Next, a qualitative analysis of discrepancies was undertaken (NVivo).

Findings: There are no statistical differences in the perception of creative identities of a creator, artist, manager, entrepreneur, and leader between citizens of Poland and citizens of other countries. The additional qualitative analysis exposed that differences in perception of the creative identities between investigated societies might have necessary consequences while managing or leading groups (and organizations) dominated by creative individuals. These differences are shown in detail, and links between our research results and the literature are built.

Value Added: It looks like a post-communist burden in current Poland has a minimal impact on the perception of creative individuals. Thus, it can be said that communism disappears from the social capital during one generation (ca. 30 years).

Recommendations: Further research exploring the perception of creative identities by different analogical groups of compared societies would be valuable.

Authors: Magbool Hassan M. , Zeyad Abdullah M.
Published: September 2021

The aim of this work involves studying the impact of varied types of steel fibers (SF) on the performance of self-compacting concrete (SCC), containing volcanic pumice powder (VPP). In this study, five types of steel fiber, which had a hooked end with two lengths of (SF1) and (SF3), flat end of length (SF2), in addition to the pointed end of (SF4) and (SF5) by 1% of volume fraction, were used. In addition, hybrid steel fiber (a mixture of all the steel fiber types) by 0.2% of volume fraction of concrete volume was used. Moreover, VPP was utilized by 30% cement mass as a substitute material for producing SCC. The impact of steel fiber properties in the shape of SF on the fresh concrete properties as slump flow and segregation were investigated. In addition to their influence on the compressive strength, split tensile strength, flexural strength, toughness, porosity, water absorption, and bulk density were examined. The results showed that SF led to decreasing the SCC fresh properties. Utilizing SF, on the other hand, improved the SCC hardened properties, as well as the toughness indices.

Authors: Dewi Winda Kusuma , Anam Choirul , Hidayanto Eko , Nitasari Arrum , Dougherty Geoff
Published: September 2021

Purpose: The aim of this work was to establish the relationships of patient size in terms of effective diameter (Deff) and water-equivalent diameter (Dw) with lateral (LAT) and anterior-posterior (AP) dimensions in order to predict the specific patient dose for thoracic, abdominal, and pelvic computed tomography (CT) examinations.

Methods: A total of 47 thoracic images, 79 abdominal images, and 50 pelvic images were analyzed in this study. The patient’s images were retrospectively collected from Dr. Kariadi and Kensaras Hospitals, Semarang, Indonesia. The slices measured were taken from the middle of the scan range. The calculations of patient sizes (LAT, AP, Deff, and Dw) were automatically performed by IndoseCT 20b software. Deff and Dw were plotted as functions of LAT, AP, and AP+LAT. In addition, Dw was plotted as a function of Deff.

Results: Strong correlations of Deff and Dw with LAT, AP, and AP+LAT were found. Stronger correlations were found in the Deff curves (R2 > 0.9) than in the Dw curves (R2 > 0.8). It was found that the average Deff was higher than the average Dw in the thoracic region, the average values were similar in the abdominal and pelvic regions.

Conclusion: The current study extended the study of the relationships between Deff and Dw and the basic geometric diameter LAT, AP, and AP+LAT beyond those previously reported by AAPM. We evaluated the relationships for three regions, i.e. thoracic, abdominal, and pelvic regions. Based on our findings, it was possible to estimate Deff and Dw from only the LAT or AP dimension.

Authors: Wysocka-Rabin Anna , Dobrzyńska Magdalena , Pasicz Katarzyna , Skrzyński Witold , Fabiszewska Ewa
Published: September 2021

Introduction: Advances in digital detector technology and methods of image presentation in digital mammography now offer the possibility of implementing mathematical assessment methods to quantitative image analysis. The aim of this work was to develop new software to simplify the application of the existing international standard for DQE in digital mammography and show in detail how it can be applied, using a Siemens Mammomat Inspiration as a model.

Material and methods: Consistent with the IEC standard a 2 mm Al filter at the tube exit and images in DICOM format as raw data, without applying any additional post-processing were used. Measurements were performed for W/Rh anode/filter combination and different tube voltage values (26 ÷ 34 kV) without any anti-scatter grid. To verify new software doses ranging from 20-600 µGy were used in measurements. Exposure (air kerma) was measured using a calibrated radiation meter (Piranha Black 457, RTI Electronics AB, Sweden). MTF was determined, using an edge test device constructed specifically for this work.

Results: It has been demonstrated that with the new software the DQE can be measured with the accuracy required by the international standard IEC 62220-1-2. DQE has been presented as a function of spatial frequency for W/Rh anode/filter combination and different tube voltage.

Conclusions: New software was used successfully to analyze image quality parameters for the Siemens Mammomat Inspiration detector. This was done on the basis of an internationally accepted methodology. In the next step, mammographs with different detector types can be compared.
The Church on the Hill in Schäßburg/Sighişoara. A Jewel of Architecture and Art-History on a Marginal Spiritual-Liturgical Existence
Authors: Fröhlich Hans Bruno
Published: September 2021

The Evangelical Church C. A. in Romania has an impressive treasure trove of churches of cultural and art-historical value in Transylvania. One of the most important sacred buildings is the Church on the Hill in Schäßburg/Sighisoara. But although it is a liturgically important space, it has served other purposes over and over again in the course of history. The fact that the Evangelical community became very small after 1989 brought with it the challenge of using this place of worship adequately. In the last few decades – i with the inclusion of the old town of Schäßburg on the list of UNESCO as a World Heritage Site – the Church on the Hill has become a tourist magnet. Culture lovers can listen to contemplative organ concerts. Due to the epidemiological situation, it now serves more and more liturgical purposes.

Authors: Karsou B. , Samara R.
Published: September 2021

This study investigated the role of endogenous Palestinian plant extracts in inducing wheat and barley resistance systems against loose smut disease with the aim to alternate the chemical pest control with natural fungicides. Twenty indigenous herbal plant extracts and essential oils were assessed for their biological and antifungal properties against Ustilago tritici and Ustilago nuda. Their potential role in inducing resistance pathways was studied on four different cultivars of wheat and barley. Two common enzyme indicators – guaiacol peroxidase (POX) and polyphenol oxidase (PPO) – are expressed in plants only after physical or chemical induction. The antifungal activity of the plant extracts was investigated in vitro. Totally 70 % of the plant extracts showed antifungal activity against Ustilago tritici and Ustilago nuda. Coridothyme extracts ranked first (61 %) in the fungal growth inhibition, followed by varthemia, salvia, ambrosia, artemisia, and lemon thyme. Some plant extracts significantly increased the POX and PPO effect compared to control for all the wheat and barley cultivars tested. The study revealed that oregano, clove or lavender and pomegranate, common yarrow or chamomile oil effectively induced the resistance indicator enzymes in wheat and barley.

Published: September 2021

Indonesia does not guarantee legitimately English as a second language. However, numerous Indonesian schools officially teach English, including pesantren (Mawardi, Maulidiansyah, Kamal, Nasai, 2019). Historically, the pesantren is an Islamic educational institution that teaches students through classical Islamic books (Fadhilah, 2011). Now, pesantren has been teaching modern lessons, including foreign languages such as English (Tahir, 2015). This study was designed to investigate the pesantren's readiness for English programs. Data collection was done by interview, observation, and documentation. Participants are people who are closely related to the object of research. A total of two English language coordinators were interviewed to obtain data on the pesantren's readiness for the English programs. The researchers also did observation and documentation to obtain supporting data from the research objects. The findings reveal that the pesantren's readiness for English language programs is outstanding in terms of the kinds of English programs, teachers' contributions, supporting facilities, and the pesantren environment itself. These findings are in line with previous researchers' findings, such as Insan (2019), Yulistiya (2020), and Setiawati (2018), stating that there are excellent programs for the advancement of students a foreign language.

Published: September 2021

The objectives of this research were to find out the types of language learning strategies employed by higher and lower achieving students on speaking skill and to find out the impacts of language learning strategies employed by them. A questionnaire was used as the instrument of this study. The sample of this research were 82 students who were chosen based on the criteria: (1) the students already passed all the Speaking I to IV classes, (2) the students consist of higher achieving students (score ≥B) and lower achieving students (score ≤C), and (3) the students allowed the researcher to obtain their speaking scores. Thus, purposive sampling was used here. In this research, the researcher used Strategy Inventory for Language Learning (SILL) by Oxford (2003) to determine the students’ language learning strategy. The result revealed that the higher achieving students used memory, cognitive, compensation, metacognitive, affective, and social strategies in learning speaking. On the other hand, the lower achieving students generally did not use the learning strategies in their learning activities. Therefore, as the impact of this learning habit, they do not possess a good speaking ability and achieve low scores in speaking class.

Doctoral studies in the Czech Republic are highly individualized with little coursework outside the supervisor/supervisee dyad, and the PhD students are mandated to publish prior to the dissertation defense. This mandate is troublesome because writing development has been on the fringes of the Czech education culture. In addition, the publications often must be in English, and many doctoral students struggle with English. In this exploratory study, we examined how this mandate translates into practice, how doctoral students learn to meet the requirements and how university administrators/supervisors perceive doctoral writing development. To answer our questions, we interviewed 7 university administrators/dissertation supervisors and 7 doctoral students from various backgrounds and universities, looking for diverse views on the issue. Our analysis confirmed the formal status of supervisors as the key doctoral writing literacy brokers. While the supervisors acknowledged their role, they also tended to view doctoral writing as a matter of self-study and funding, thus indirectly emphasising the publication outcomes. In contrast, doctoral students called for structured support of their writing processes. We propose a systemic approach to introduce writing pedagogies into the Czech discourse. With this study we hope to contribute to research on doctoral writing for publication of EAL (English as an Additional Language) students in Central Europe.
Power, Politeness and Liquid Persona
Authors: Glimäng Malin
Published: September 2021

This article explores pre-service English teachers’ self-reflections as participants in online intercultural exchange (VE). The aim is twofold: to examine participants’ perceptions of intercultural experiences in response to VE; and, to understand whether and how teacher trainees gain pedagogical insights through self-reflection situated in a cross-cultural online project. The study draws upon two iterations of exploratory research in a VE-project carried out with two cohorts of student groups. The first cycle involved students in Indonesia and Sweden, and the second cycle, a three-way collaboration, involved students in Argentina, Poland and Sweden. This article focuses on the Swedish side and examines empirical data incorporating e-diaries and interviews. A qualitative transcript analysis generated three intersecting themes: language and power, politeness, and participation through digital tools. Two theoretical constructs provide the analytical lens: persona (Hinrichsen & Coombs, 2014) and liquid interculturality (Dervin & Dirba, 2006). The findings challenge fixed notions of identity and interculturality, showing how participants engage in negotiations and fluid constructions of persona in response to perceived expectations of their interlocutors. The findings also indicate affordances of VE as a lingua franca contact zone in developing pre-service English teachers’ self-awareness and pedagogical competences.
Relationen mellan lärares intentioner och deras respons till elever
Authors: Balan Andreia , Jönsson Anders
Published: September 2021

Formative feedback has the potential to support student learning and performance. However, teachers sometimes have difficulties realizing their intentions with formative feedback when responding to students’ questions or solutions. If the actual response provided does not agree with the teacher’s intentions, the formative potential may be diminished or lost. The purpose of this study is therefore to investigate whether teachers themselves are able to identify the correspondence between their stated intentions and their actual response to students. Four teachers participated in the study by responding to the mathematical reasoning performed by twelve students in grades 4-5 (the feedback situations were recorded) and then taking part in stimulated-recall interviews. The results show that the teachers were able to identify certain instances of correspondence, and/or differences, between their intentions and how they acted in the feedback situations. The differences identified by the teachers were justified based on the teachers’ individual beliefs – for instance, the belief that some mathematical methods belong to certain grade levels and should not be taught in advance – or on concerns about how the students would react.

В этом обзоре рассмотрено влияние различных типов промышленного загрязнения на макро- и микроморфологию хвои и листьев древесных растений. Выделены специфические и неспецифические реакции разных древесных видов как на один и тот же техногенный фактор, так и на разные виды воздействия, включая искусственную фумигацию и внесение токсикантов в среду. Показана относительная независимость адаптивных реакций в пределах листа и хвои, несмотря на единство и целостность этих органов. Обсуждаются причины данных поливариантных реакций, лежащие в основе адаптивного потенциала, принципа множественного обеспечения биологически необходимых функций для сохранения гомеостаза, толерантности видов к техногенезу.

This document is an output from the “Voices After Disaster: narratives and representation following the Kerala floods of August 2018” project supported by the University of East Anglia (UEA)’s GCRF QR funds. The project is carried out by researchers at UEA, the Indian Institute for Human Settlements (IIHS), the Indian Institute of Technology (IIT), Bombay, and Canalpy, Kerala. In this briefing, we provide an overview of some of the emerging narratives of recovery in Kerala and discuss their significance for post-disaster recovery policy and practice. A key part of the work was a review of reported recovery activities by government and NGOs, as well as accounts and reports of the disaster and subsequent activities in the media and other information sources. This was complemented by fieldwork on the ground in two districts, in which the teams conducted a total of 105 interviews and group discussions with a range of community members and other local stakeholders. We worked in Alleppey district, in the low-lying Kuttanad region, where extreme accumulation of floodwaters had been far in excess of the normal seasonal levels, and in Wayanad district, in the Western Ghats, where there had been a concentration of severe flash floods and landslides.
Demographics of the Sami population of Kolsky Uyezd in the late XVIII century (based on the statistical report of 1764)
Authors: Chaplygina Daria Aleksandrovna
Published: September 2021

The selected topic is at the intersection of such relevant trends of historical science as the history of popular sources, history of demographic processes of the Russian population, and regional history. The appeal to statistical data allows revealing various socioeconomic and demographic indicators, for example: the size and structure of the population, displacement of population, gender and age composition, matrimonial relations, as well as the regional peculiarities of demographic development. The subject of this research is the demographics of the Sami people of Kolksy Uyezd in the late XVIII century. The object of this research is the statistical report of 1764 compiled by order of the governor of Arkhangelsk E. A. Golovtsyn. The history of the Russian North overall and Kolsky Uyezd in particular is studied nonuniformily. The novelty of this article lies in the fact that in the Russian historiography there are no special research dedicated to the demographics of Kolsky Uyezd of that period. The statistical report of 1764 was introduced into the scientific discourse by S. A. Nikonov a short while ago. By giving a more detailed perspective on the subject matter, it draws interest in comparison with other sources used for studying the historical demographics of the region. The following conclusions were made: the main social institutions of the Sami people in the late XVIII century were “pogost” and “vezha”; vezha represented a collective that consisted of four or more families that usually were not blood-related; unlike other sources, statistical report of 1764 has records on the growing male population of the Sami population of Kolsky Uyezd; lineal consanguinity was a prevalent type of family, which included two generations.

Traditionally, Vitamin D has been associated primarily with bone health, while further investigations revealed that a sufficient amount is important for many organ functions. Data of 314 individuals were obtained from Erbil governorate public and private hospitals from patients admitted to there for testing their level of Vitamin D and other tests according to their doctor’s prescription. The variable related to their lifestyle, metabolic syndrome, and hematology evaluations were obtained. The body mass index , number of sleeping hours, number of hours spent with electronic devices, serum lipid level anemia-related tests were measured. The results showed that serum 25(OH) Vitamin D levels in studied individuals were related to hyperlipidemia serum cholesterol measures. The level of Vitamin B12 and Iron status were lower in the Vitamin D deficiency (VDD) individuals. Mean platelet volume was higher in vitamin-deficient patients which induces the risk of cardiovascular (CV) diseases. This finding suggests the relation between VDD and metabolic syndrome, CV, and anemia-related measurement.

Published: September 2021

Mycelium-based composites result from the growth of filamentous fungi on organic materials such as agricultural waste streams, like sugarcane bagasse, sawdust, coffee husks, coconut mesocarp and cotton. The morphology, density, tensile, flexural and compression strength of mycocomposites change according to the type of substrate, fungal species and processing technique. The objective of this study was to evaluate the mechanical behaviour in compression of different mycelium-based materials changing the fungal species. Substrates were formulated with wood sawdust and coconut endocarp, coffee grounds and wheat bran and incubated with isolates of the fungi Pycnoporus sanguineus, Ganoderma applanattum and Hexagonia hydnoides. Pre-myceliated sterile substrates were placed in cylindrical molds and incubated at 25°C for 7 days. After this period, the composites obtained were subjected to a temperature of 80 °C for 12 hours to stop fungi further development. Mechanical tests showed the relationship between the fungi and the compressive resistance (10% strain) of resulting composites, according to ASTM D1621. The analyzes indicated that the use of Pycnoporus sanguineus fungusprovides a composite with greater resistance to compression, which suggests the application of this mycocomposite in packaging, since the primary requirement of such use is to protect the content against damage.

Duplex stainless steels are essential for many industries. Regularly used in highly aggressive environments, they often undergo a welding process, whether for joining components or repair operations. This process can modify the ferrite/austenite ratio and form secondary phases, impairing its properties. As a result, in some cases, it is recommended that post-welding heat treatment be carried out to restore the mechanical and metallurgical properties of the welded joint. In this work, the effect of solubilization heat treatment on the mechanical properties of duplex stainless steel welded joints by the autogenous Tungsten Inert Gas (TIG) process is studied. A systematic review was performed in the Scopus database to understand the effects of post-welding heat treatments on microstructure, hardness, tensile and impact behavior. Two solubilization temperatures were chosen through this review: 1050 °C and 1150 °C during 15 min. These thermal treatments were carried out in 3 tensile test specimens of each condition studied, including the welded joint without any heat treatment, called as-received condition. The heat treatments resulted in higher elongation and lower yield stress and stress strength. The one-way ANOVA showed no significant difference between yield strength, tensile strength and elongation between heat-treated conditions specimens. Although, the region where the specimens fractured varied. In the future, a microstructural characterization will be performed to understand the mechanical behavior observed

The impact of rapid prototyping on undergraduate engineering universities using a single machine or a wide variety of prototyping techniques is a lot discussed by many authors. In the past, manufacturing real models using a variety of model creation processes has enhanced graduate students' product design skills. The main advantage is the ability to verify different hypotheses research parameters and allow for improved project completion, reducing the costs of manufacturing instrumentation and test configurations, reducing the design-test-review cycle time, and presenting students with classes more practices and research problems. Thus, the experimental study through the reduced model of the rotor of a hydraulic turbine has its importance based on the fact that it is possible to analyze its behavior in the laboratory itself. The present work aimed to design, model and manufacture, through a 3D printer, a reduced model of the Pelton turbine rotor for didactic use. The turbine rotor was dimensioned based on the project input data such as: head drop, turbine power, engine speed, pressure coefficient and efficiency. The rotor disk diameter of 375.75 mm was obtained, where 25 shells will be assembled. The manufactured model will be printed to compose a didactic bench later built for use in practical classes. This bench will be a tool for experimental research studies, and also as a didactic resource in subjects such as fluid mechanics and flow machines, taught in the undergraduate course in Mechanical Engineering, as a way of internalizing the content learned in the classroom.

The realization of actions aimed at sustainable development is unquestionable. As the technological improvement increases every day, the possibility of reusing different wastes to replace the use of natural resources in the development of construction materials is growing, since the wastes and byproducts from other industries have a significant representation in the volume of solid waste generated in the country. Aiming at the need to reuse waste, this work aimed to develop a multi-purpose mortar for use in construction with waste glass industry, in order to replace part of the binder material (Portland cement) by waste glass in percentages of 0, 5, 15 and 20%. The methodology used consisted of the experimental program that consists of the characterization of the materials used for the production of the multiple-use mortar, as well as the execution of technological tests of mortars in the fresh and hardened states. According to the results, it was possible to observe that the analyses made both on the residue and on the properties of the fresh and hardened state of the mixture, it was possible to verify that the influence of the residue in the mixture presented in its composition a 68% concentration of silicon oxide (silica), one of the main components of cement. In view of the aspects analyzed, it was concluded that the mortar with the replacement of Portland cement by glass waste showed better results regarding the porosity of the mortar since the capillary water absorption coefficient was the lowest among all mortars.

Groundwater is an important source of supply, is available in almost all regions of the Earth, constituting an important natural resource. In addition, having knowledge of this resource in terms of quality and quantity is of paramount importance, as these waters are often used for human supply, for irrigation in rural areas and for industrial purposes. In this context, the North Fluminense region, especially the municipality of Campos dos Goytacazes, has been demanding more and more for the use of water resources, due to the population and business increase, motivated, above all, by the huge undertaking that is the Açu port complex, installed in the neighboring municipality, São João da Barra. This reality points to the relevance of developing work that will contribute to a better knowledge of groundwater. This research aims to contribute to a better knowledge of the water quality of the shallow free aquifers in the municipality of Campos dos Goytacazes. As for the methodology, the following steps will be carried out: collection of bibliographic and documentary data, such as conference proceedings, books, ordinance, laws, articles, theses, dissertations, and others; literature review; selection of physicochemical data from existing shallow wells; comparison of physical-chemical parameters with the maximum values allowed with Consolidation Ordinance Nº. 5 established by the Ministry of Health; map creation; and elaboration of table and graphs. It is expected with this research to produce and make available information that can contribute to the sustainable management of underground water resources in the municipality of Campos dos Goytacazes

With the popularization of internet access and smartphones, people spend much of their time accessing content through their cell phones. In this context, the way in which the individual interacts with organizations has also been changing significantly: the figure of the active consumer, who shares content and engages with brands, emerges. This work aimed to analyze different types of content as tools for engaging and creating an audience formed by engineering students. The initial stage of the methodology consisted of defining the target audience. After that, the brand was created, a logo was designed and the fonts and colors were chosen. After creating a page in a social network, different content creation strategies were adopted - varying parameters such as type, format and subject - to build an audience, and engagement metrics were evaluated - likes, comments, shares and "saves” – to see which are the most effective strategies for raising the number of followers. The chosen target audience was composed of young engineers and engineering students, under the age of 35, and the main channel chosen for sharing the content was Instagram. The characterization of the followers showed that most of them are between the 1st and 8th period of the engineering course, with the majority belonging to the mechanical engineering course (44%), followed by civil (22%) and production (11% ) engineering. The types of content that were most relevant, according to the engagement metrics, were: tips from courses, movies and books; curiosities; generic technical content and technical content for mechanical engineering, which may reflect the higher numbers of this course observed in followers. Furthermore, publications where the visual aspect presented a pattern, the authors showed themselves or that promoted some type of interaction with the public also obtained better results in general. Thus, it can be concluded that the best strategy for the growth of the page involved the creation of mixed content between tips for extracurricular activities, basic technical content and curiosities. The visual aspect and interaction with the public were also important.
