Authors: Atkinson Justine , Bulbulia Firdoze
Published: June 2021

As a result of the global COVID-19 pandemic and resulting lockdowns across the world, digital access has become paramount, as most aspects of education have moved online. Drawing together five case studies located in South Africa, Argentina, the Netherlands, India and Ethiopia, this article assesses the role of film education during the COVID-19 pandemic, with a specific focus on the impacts of digital access. We examine multimodal forms of film education, and how these were used to inform, entertain and educate children during the crisis by the varying work undertaken by the organizations. Applying theories of intersectionality, we address the need for context-specific approaches to film education, focusing upon the impact that the societal and individual contexts had on the dissemination of film education in each country.

Published: June 2021

The present research focused on identifying the influence of cognitive processes in the creative lateral thinking of high school students. The work was developed under the positivist paradigm; it was classified as basic, of explanatory level, with quantitative approach, non-experimental design and cross-sectional. The sample, calculated through probabilistic sampling, consisted of 221 students. Two data collection instruments were used: the cognitive processes questionnaire and the lateral thinking questionnaire, which were subjected to content validity by expert judgment and reliability and internal consistency analysis by Cronbach's alpha, reaching values of 0.908 and 0.802, respectively. The analysis of verification by Spearman's rho obtained was 0.762, which determined the significant influence between cognitive processes and lateral thinking. It was concluded that, if procedures and actions that lead to the acquisition of knowledge in a constructive way and by discovery are practiced, creative and perceptive lateral thinking would be developed; then the individual would exhibit imagination and creative behaviors.
Atmospheric Emissions Effects and Mechanism
Authors: Abdullah Abdullah A.
Published: June 2021

Humanity's relationship with the environment is a delicate balance. Since the industrial revolution, the world's population has grown at an exponential rate, and this has a major environmental effect. Deforestation, pollution, and global climate change are just a few of the negative consequences of population and technological growth. Particulates, Sulphur dioxide (SO2), and nitrogen oxides (NOx) are the primary pollutants that harm our health. These contaminants may be directly emitted into the atmosphere (primary pollutants) or formed in the atmosphere from primary pollutants reacting (secondary pollutants. Tropospheric ozone is created When water reacts with volatile organic compounds (VOC) and nitrogen oxides (NOx) in the presence of sunlight, nitrogen dioxide is produced. is formed when NO is oxidized, as Sulphur dioxide or nitrogen oxides react with water, acid rain results. These contaminants have negative consequences for human health (low concentrations cause eye, nose, throat, and lung irritation) and the environment, as they contribute to acidification and eutrophication, as well as the formation of particulates and tropospheric ozone (photochemical smog). Electricity production and the combustion of fossil fuels in high-temperature manufacturing processes is the primary source of SO2 and NOx. Particulates are as a direct product of any type of industrial combustion or heating. Particulates and nitrogen oxides (NOx) are two types of contaminants. also linked to traffic and transportation. All these molecules of greenhouse gases that penetrate the atmosphere It's called atmospheric emissions. In order to meet the Paris Agreement's goal of maintaining a 1.5°C average global temperature increase, net CO2 emissions must reach zero by 2050, implying that the amount entering the atmosphere must exceed the amount absorbed by natural and technological sinks.

Published: June 2021

In the theoretical part, removal of direct yellow 8 (DY8) from water solution was accomplished using Bentonite Clay as an adsorbent. Under batch adsorption, the adsorption was observed as a function of contact time, adsorbent dosage, pH, and temperature. The equilibrium data were fitted with the Langmuir and Freundlich adsorption models, and the linear regression coefficient R2 was used to determine the best fitting isotherm model. thermodynamic parameters of the ongoing adsorption mechanism, such as Gibb's free energy, enthalpy, and entropy, have also been measured. The batch method was also used for the kinetic calculations, and the day's adsorption assumes first-order rate kinetics. The kinetic studies also show that the intraparticle diffusion process was active. Density Functional Theory (DFT) was used to study the dye structure with Gaussian 09 and predict the active site in a molecule using total electron density (TED) and electrostatic surface potential (ESP).

Published: June 2021

Myotis lavali is an insectivorous bat that occurs along the South American Dry Diagonal, extending from the Brazilian Caatinga southward to Paraguayan Alto Chaco. This species was described recently and there is little information about its biology. Herein, we describe the conventional karyotype from three males captured in an arboreal savanna from Vale do Jequitinhonha, State of Minas Gerais, Brazil. The diploid number (2n) and the fundamental number of autosomes (FNa) were 44 and 50, respectively. Its karyotype, in Giemsa staining, is similar to others described for Neotropical Myotis, and it is not useful to identify specimens.
A Scale for Quantifying Behavior Based on Aggressiveness in Bats
Authors: Teresa Shapiro Julie , A. Stanton Jr. Richard , A. McCleery Robert , Monadjem Ara
Published: June 2021

Behavior and personality play a crucial role in the evolution and ecology of animal species. We have limited knowledge of bat personality traits, partially due to the time, equipment, and facilities needed to measure them. To help fill this gap, we developed a scale for quantifying aggressiveness in bats that can be used during ordinary fieldwork and handling by researchers. This scale is based on observations of the following ecologically relevant and easily observed behaviors in wild-captured bats during routine handling: amount and intensity of physical struggling, teeth-baring, and biting. We then applied this scale to 35 wild-caught individual bats belonging to three different species or species groups (Chaerephon pumilus, n=29; Scotophilus dinganii, n=3; and pipistrelloid bats, n=3) and measured agreement between observers using intraclass correlation coefficients (ICCs). We found that agreement between observers was good to excellent. This scale of aggressiveness provides an important, practical tool for researchers to reliably quantify this personality trait in wild bats that requires no additional equipment and minimal additional handling time. Collecting data on aggressive behavior during handling has the potential to increase our understanding of both intra- and interspecific variation in aggressiveness in bats, as well as the influence of this trait on many aspects of bat ecology. Finally, collecting data using this scale can facilitate comparisons between studies and promote research at broader spatial and temporal scales than commonly used in behavioral ecology studies.
STEREOTIP TENTANG DIFABEL: SEBUAH PERSPEKTIF KOMUNIKASI LINTAS BUDAYA

Published: June 2021

This paper will describe the study of stereotypes in persons with disabilities, from the perspective of intercultural communication. During this time people with disabilities often get a bad stigma and are still underestimated as a party that needs to be pitied. For families, sometimes people with disabilities are considered a disgrace that needs to be covered up. The assumption that people with disabilities are different and even abnormal is shown as a form of negative perception that is nothing but part of the stereotype. Stereotype is not only from the labeling process of the community, but also the labeling process carried out by the diffable to himself who is aware of the disabilities that he has. Communication difficulties will arise from stereotyping, which generalizes people based on little information and shapes people's assumptions based on their membership in a group. In other words, stereotyping is the process of placing people into established categories, or judgments about people or objects based on appropriate categories, rather than on their individual characteristics. In the study of intercultural communication, stereotyping is the categorization of a group in general by ignoring individual differences. These groups include: racial groups, ethnic groups, the elderly, various professional occupations, or people with certain physical appearance. Stereotype does not view individuals in the group as unique people or individuals
Preparation and Role Performance of Heads of Secondary Schools in the Ashanti Region of Ghana: Lessons to Draw
Authors: Boadu Kankam
Published: June 2021

This study examined how Senior Secondary School heads were prepared for their roles and if their preparation have bearings on their role performance. The research design adopted for this study was descriptive survey. In all, a sample of 51 heads of Senior Secondary School in the Ashanti Region of Ghana were purposively selected and assessed. A 21-item questionnaire consisting of both open and close ended items was used. The data was analysed using percentages and chi-square. Analysis of the data showed that majority of the heads have not had any advanced preparation for their roles and that they faced challenges in their day to day performance of their roles. The recommendations made among other things are that there should be succession plan for prospective heads of institutions so that when they eventually assume heads positions, they are not found wanting.  More so, there should be manuals for heads of institutions to guide the newly appointed. Lastly, it is recommended that regular seminars and in-service training be organised for heads of institutions so that they share ideas and learn from best practices.
Reexamining Doctoral Education: A framework for Leadership in the Context of Practice
Authors: Aguloye Olajide
Published: June 2021

Traditionally, doctorate in education is pitched on two platforms. The Doctor of Philosophy (Ph.D.) is pitched as belonging exclusively to the domain of research and scholarship, while the Doctor of Education (Ed.D.) is pitched as belonging to the domain of active professional practice. This distinction is dysfunctional to bridging the gap between research in the academe and research in professional practice. Research in the academe is often insular with theoretical intents and with outcomes that have limited utility for solving active problems of or in practice in education. This misguided distinction can be corrected through a new thinking of the educational purpose and outcome-expectations for Ph.D. and Ed.D. programs in education. Doctoral education, irrespective of nomenclature (Ph.D. or Ed.D.) should be envisioned as leadership platforms through which knowledge and practice is used seamlessly to continuously ignite innovation and transformation in education. This paper proposes a framework for reexamining doctoral education and their comparative relevance in solving problems of and in practice. The paper aims to position the two doctoral education pathways as platforms for developing leaders who promote the generation and application of knowledge on solutions to problems of and in practice. Author presents a conceptual model that explores the two doctoral pathways through the lens of application of knowledge, research, and practice. Further research is proposed on how doctoral education can enhance practice in educational leadership and foster continuous improvements in education.
effects of COVID-19 Pandemic on the Psyche and Productivity of Pharmaceutical Sales Workforce in an African Country; A descriptive case study
Authors: OAMEN Theophilus Ehidiamen
Published: June 2021

Pharmaceutical sales representatives are a pivotal workforce in the healthcare system. Due to the global impact of COVID-19, the impact on the psyche and morale of the pharmaceutical sales workforce has to be examined. The primary objective of the study was to assess the possible impact of the COVID-19 pandemic on the psyche and productivity of the pharmaceutical sales workforce in Nigeria. A questionnaire-guided cross-sectional survey was used to collect data from pharmaceutical sales personnel across the six geopolitical zones in Nigeria using purposive sampling. The final sample was 225. Statistical analysis was done using SPSS 25. Descriptive statistics such as mean, standard deviation were used for demographic data. Cluster analysis was used to identify key demographic predictors of importance. X2 test was used to test the association between the sociodemographic characteristics of respondents and work-attributes. The difference of means was determined with a t-test. Highest and lowest-ranked work-attributes were information provider (3.62±1.36), and involvement in COVID screening activities (1.80±1.20). Average daily work hours before and during COVID-19 lockdown (2.16±0.04 vs. 1.88±0.11, p<0.05)) were affected. Average sales were significantly affected (3.15±0.48 vs. 1.35±0.36, p<0.0001). Psychological states of Anxiety and Increased burden have a medium to high impact on the psyche of respondents. The study revealed an association of both extremes of pessimism and optimism with regards to Frustration state of mind. Study suggests an overall negative impact on pharmaceutical sales representatives’ psyche and productivity. Attention to sales workforce welfare is required to safeguard medicine supply.
Demonstrating the capacity of the National Advisory Committee on Immunization for timely responses to post-market vaccine monitoring signals: Canada’s experience with the live-attenuated influenza vaccine
Authors: Zhao Linlu , Young Kelsey , House Althea , Stirling Rob , Tunis Matthew
Published: June 2021

Over the last several years, the recommended use of the live-attenuated influenza vaccine (LAIV) for children has evolved in the United States (US) in response to evidence of a potential decrease in LAIV effectiveness based on post-market monitoring. These issues were not observed in Canada or elsewhere; consequently, recommendations from Canada’s National Advisory Committee on Immunization (NACI) and the US Advisory Committee on Immunization Practices (ACIP) on whether to use LAIV differed for two influenza seasons (2016–2017 and 2017–2018). This retrospective describes how NACI arrived at its recommendations in response to post-market signals of reduced LAIV performance from the US in 2013–2014 and again in 2015–2016. NACI’s experience with LAIV marks the first time in Canada where a preferential recommendation on the use of an influenza vaccine in a routine immunization program was reversed. This experience highlights the importance of ongoing post-market monitoring of vaccines, international collaboration and careful consideration of local context to inform vaccine recommendations. NACI’s capacity for timely responses to post-market vaccine performance signals will facilitate responsiveness to similar post-market monitoring signals from the coronavirus disease 2019 (COVID-19) vaccines.
Stare druki pochodzące z klasztorów skasowanych w Wielkopolsce w zbiorach Biblioteki Uniwersyteckiej w Warszawie
Authors: Czapnik Marianna
Published: June 2021

W zasobach Biblioteki Uniwersyteckiej w Warszawie dotychczas zarejestrowano 3091 woluminów należących do historycznych wielkopolskich bibliotek klasztornych. W artykule omówiono poszczególne etapy napływu fragmentów kolekcji, które zasiliły zbiory biblioteczne warszawskiej książnicy uniwersyteckiej w początkowych latach XIX wieku. Pierwsze z nich pochodziły z biblioteki Liceum Warszawskiego (1806) i tzw. Biblioteki przy Sądzie Apelacyjnym (1810). Analiza znaków i zapisów własnościowych zachowanych egzemplarzy pozwala stwierdzić, że w obu bibliotekach znajdowały się księgi należące uprzednio do klasztorów cysterskich z Bledzewa, Obry, Paradyża i Wągrowca, benedyktynów z Lubinia oraz trynitarzy z Krotoszyna. Akt kasacyjny z 1819 roku spowodował napływ znacznych partii księgozbiorów z bibliotek jezuitów i kanoników regularnych laterańskich z Kalisza, cystersów z Lądu, kamedułów z Bieniszewa oraz paulinów z Brdowa i Wielgomłynów. W zbiorach Biblioteki Uniwersyteckiej w Warszawie znalazły się także woluminy z bibliotek jezuitów i karmelitów bosych z Poznania, włączone z fragmentami innych kolekcji lub w sposób dotychczas niewyjaśniony. Przedstawiono pokrótce zapisy i inne znaki własnościowe umożliwiające identyfikację egzemplarzy z wymienionych bibliotek: pieczątki, typowe zapiski klasztorne, nalepki z sygnaturami bibliotecznymi oraz charakterystyczne oznaczenia na grzbietach opraw.
Odkrywanie sensu życia w starości
Authors: Kluz Marek
Published: June 2021

Niniejsza publikacja ma na celu przybliżyć aktualny problem ludzi starszych, którzy w dobie dzisiejszych wynalazków i rozwoju techniki tracą swoją wartość i godność. Jednak ten stereotyp człowieka starego we współczesnym świecie jest błędny,  jako że sensu starości, przy głębszej refleksji, nie sposób przeoczyć. Dostrzegając jak wiele jest zagubionych osób starszych, którym trudno odnaleźć się w obecnej rzeczywistości, słuszne wydaje się ukazanie chrześcijańskiego sensu tego etapu życia. W punkcie wyjścia został przedstawiony obraz człowieka starego w Piśmie Świętym, jako zaprzeczenie współczesnym stereotypom. A ponieważ starość naznaczona jest cierpieniem i zbliża na spotkanie z Panem, dlatego ważnym aspektem było również ukazanie sensu cierpienia jako współuczestnictwa w męce, śmierci i zmartwychwstaniu Chrystusa, jak też drogi prowadzącej na spotkanie z Nim.

Authors: Jin Xuan , Wang Li , Yang Mingzhu
Published: June 2021

Purpose

This study was to explore the toxicological mechanisms by which PM2.5 causes lung dysfunction.

Methods

The expression of circ_0038467 and miR-138-1-3p in PM2.5-induced human bronchial epithelial cell line BEAS-2B was detected by RT-qPCR. The effects of circ_0038467 and miR-138-1-3p on proliferation, apoptosis, and inflammatory cytokines (IL-6 and IL-8) in PM2.5-induced BEAS-2B were determined using cell counting kit-8, flow cytometry, western blot, and enzyme-linked immunosorbent assay, respectively. The levels of nuclear factor kappa B (NF-κB) pathway-related protein were also analyzed by western blot. The binding interaction between circ_0038467 and miR-138-1-3p was confirmed by dual-luciferase reporter assay and RNA immunoprecipitation assay and pull-down assay.

Results

circ_0038467 expression was increased by PM2.5 treatment in BEAS-2B cells in time- and dose-dependent methods, and knockdown of circ_0038467 reversed PM2.5-triggered BEAS-2B cell death and inflammatory response. miR-138-1-3p was decreased by PM2.5 treatment, and restoration of miR-138-1-3p attenuated PM2.5-induced BEAS-2B cell injury. In a mechanical study, we found circ_0038467 directly bound to miR-138-1-3p, and further rescue experiments exhibited miR-138-1-3p inhibition partially overturned the regulatory functions of circ_0038467 knockdown in PM2.5-induced BEAS-2B cells.

Conclusion

circ_0038467 provided a potential therapeutic strategy for future clinic intervention in air pollution-triggered lung dysfunction.
Security of the Middle East in Light of the Iranian Nuclear Deal
Authors: Maklad Hussein Talal
Published: June 2021

Iran’s nuclear issue is considered one of the factors that has shaped the regional dynamic in the Arab Gulf sub-region because it is a major factor that might affect the perception of the other side players in the region, international, and regional actors. This matter represents a challenge to the security of the Gulf States. This started to change after the signing of the nuclear deal known as the “Joint Comprehensive Plan of Action” (JCPOA), but then, upon the withdrawal of the Trump administration from this agreement in May 2018, regional alignments began to be reformed. It is within this context that this article tries to answer the following question: How does the American withdrawal from the JCPOA affect the stability in the region and change the stand of the Gulf countries and other regional states? This study is based on the following hypotheses. The withdrawal of the American administration from the nuclear deal, and its imposition of a “maximum pressure” policy, represented a turning point in the vision of the region and has again cast the shadow of the Cold War over the Gulf area. The American withdrawal from the nuclear deal is an independent variable, while the regional security system and the policy of the Gulf States toward this deal is the dependent variable.

Experimental investigation of cutting temperature and surface roughness for different cutting fluids during turning of Duplex stainless steel-2205 under minimum quantity lubrication technique
Authors: S T Prashantha Kumar , Prasada HP Thirtha
Published: June 2021

Duplex stainless steel (DSS)-2205 comes under hard to machine material owing to its inherent properties but more applications in severe working conditions hence, selection of turning process parameters and suitable cutting fluids of DSS-2205 is essential. In the present work, investigate the performance of Deionized water, neat cut oil, and emulsified fluid on cutting temperature and surface roughness during turning of duplex stainless steel-2205 under minimum quantity lubrication technique. Based on a face-centered composite design, 20 experiments were conducted with varying speed, feed, and depth of cut in three levels for three different fluids. Analysis of variance (ANOVA) is used to identify significant parameters that affect the response. Numerical optimization was carried out under Desirability Function Analysis (DFA) for cutting temperature during deionized water cutting fluid for surface roughness during emulsified cutting fluid. Depth of cut is the significant factor for cutting temperature contribution is 74.83% during Deionized water as a fluid, and feed is the significant factor for surface roughness contribution is 93.57% during emulsified fluid. The optimum cutting parameters were determined for speed (50m/min), feed (0.051mm/rev) and depth of cut (0.4mm). Experimental results revealed that Deionized water gives better results for reduced the cutting temperature and emulsified fluid for surface roughness reduction.
An experimental investigation on mechanical performances of 3D printed lightweight ABS pipes with different cellular wall thickness
Authors: Ergene Berkay , ŞEKEROĞLU İsmet , Bolat Çağın , Yalçın Bekir
Published: June 2021

In recent years, cellular structures have attracted great deal of attention of many researchers due to their unique properties like exhibiting high strength at low density and great energy absorption. Also, the applications of cellular structures (or lattice structures) such as wing airfoil, tire, fiber and implant, are mainly used in aerospace, automotive, textile and biomedical industries respectively. In this investigation, the idea of using cellular structures in pipes made of acrylonitrile butadiene styrene (ABS) material was focused on and four different pipe types were designed as honeycomb structure model, straight rib pattern model, hybrid version of the first two models and fully solid model. Subsequently, these models were 3D printed by using FDM method and these lightweight pipes were subjected to compression tests in order to obtain stress-strain curves of these structures. Mechanical properties of lightweight pipes like elasticity modulus, specific modulus, compressive strength, specific compressive strength, absorbed energy and specific absorbed energy were calculated and compared to each other. Moreover, deformation modes were recorded during all compression tests and reported as well. The results showed that pipe models including lattice wall thickness could be preferred for the applications which don’t require too high compressive strength and their specific energy absorption values were notably capable to compete with fully solid pipe structures. In particular, rib shape lattice structure had the highest elongation while the fully solid one possessed worst ductility. Lastly, it is pointed out that 3D printing method provides a great opportunity to have a foresight about production of uncommon parts by prototyping.
Refractory hypercalcaemia associated with disseminated Cryptococcus neoformans infection
Authors: Zhu Jasmine Jiang , Naughton William J , Hay Be Kim , Ensor Nicholas , Cheung Ada S
Published: June 2021

Hypercalcaemia is a very common endocrine condition, yet severe hypercalcaemia as a result of fungal infection is rarely described. There are have only been two reported cases in the literature of hypercalcaemia associated with Cryptococcus infection. Although the mechanism of hypercalcaemia in these infections is not clear, it has been suggested that it could be driven by the extra-renal production of 1-alpha-hydroxylase by macrophages in granulomas. We describe the case of a 55-year-old woman with a 1,25-OH D-mediated refractory hypercalcaemia in the context of a Cryptococcus neoformans infection. She required treatment with antifungals, pamidronate, calcitonin, denosumab and high-dose glucocorticoids. A disseminated fungal infection should be suspected in immunosuppressed individuals presenting with hypercalcaemia.

Learning point

In immunocompromised patients with unexplained hypercalcaemia, fungal infections should be considered as the differential diagnoses;

Glucocorticoids may be considered to treat 1,25-OH D-driven hypercalcaemia; however, the benefits of lowering the calcium need to be balanced against the risk of exacerbating an underlying infection;

Fluconazole might be an effective therapy for both treatment of the hypercalcaemia by lowering 1,25-OH D levels as well as of the fungal infection.
Cabergoline reduces 3-methoxytyramine in a SDHC patient with metastatic paraganglioma and prolactinoma
Authors: Hussein Ziad , Korbonits Marta , Baldeweg Stephanie E , Chung Teng-Teng
Published: June 2021

We observed a novel therapeutic response with cabergoline in a male patient with a dopamine-secreting head and neck paraganglioma (HNPGL), macroprolactinoma and germline succinate dehydrogenase C mutation (SDHC). The macroprolactinoma was treated with cabergoline which gave an excellent response. He was found to have raised plasma 3-methoxytyramine of 1014 pmol/L (NR: 0–180 pmol/L); but it was unclear if this was a drug-induced phenomenon from dopamine agonist (DA) therapy. Cabergoline was stopped for 4 weeks and the 3-methoxytyramine level increased significantly to 2185 pmol/L, suggesting a biochemical response of his HNPGL. Subsequently, Gallium-68 Dotatate PET and MRI (Gallium-68 Dotatate PET/MRI) demonstrated a second lesion in the sacrum. Both the HNPGL and metastatic sacral deposit received external beam radiotherapy with a good biochemical and radiological response.

Conclusion

Our case report highlights the rare potential of germline SDHC mutations causing metastatic paraganglioma and concurrent pituitary tumours. Cabergoline treatment may lower elevated 3-methoxytyramine levels and, therefore, mask the biochemical evidence of metastatic disease but also may have therapeutic relevance in dopamine-secreting pheochromocytomas/paragangliomas (PPGLs).

Learning points

Several neuroendocrine tumours (NETs) express dopamine D2 and D4 receptors. In this case report, cabergoline significantly reduced plasma 3-methoxytyramine level in a patient with functional HNPGL. Cabergoline might have therapeutic relevance in dopamine-secreting PPGLs.

Paragangliomas associated with SDHC mutation classically present with asymptomatic non-functional HNPGL and have rare metastatic potential.

The association of pheochromocytoma or paraganglioma and pituitary adenoma is now a well-described rare association (<1%), designated as the three P association. While the three P association is most commonly seen with succinate dehydrogenase B and D mutations, it has also been described in patients with SDHA and SDHC mutations.

Cabergoline treatment may lower elevated 3-methoxytyramine levels and mask the biochemical evidence of metastatic disease. Regular functional imaging with Gallium-68 Dotatate PET/MRI provides better evidence of metastatic disease.

W niniejszej pracy przedstawiono problem zakażeń o etiologii grzybiczej w oddziałach zabiegowych. Opisano czynniki ryzyka związane z rodzajem zabiegu i stanem odporności pacjenta oraz metody diagnostyczne z uwzględnieniem możliwości ich wykorzystania w oddziale, a przede wszystkim z ich interpretacją. W artykule krótko scharakteryzowano strategie leczenia przeciwgrzybiczego, a także leki przeciwgrzybicze ze szczególnym podkreśleniem spektrum ich działania. Celem pracy było uświadomienie personelowi medycznemu pracującemu w oddziałach zabiegowych roli diagnostyki mikrobiologicznej/mikologicznej w szybkim diagnozowaniu inwazyjnej choroby grzybiczej, która zbyt późno rozpoznana i leczona jest obarczona wysoką śmiertelnością.
Saving Tendency of Developed and Developing European Countries

In the previous literature studies, the saving condition is mainly examined focusing in Developing countries and Asian countries. The examination on the saving condition is crucial due to the linkages between saving accumulation and economic growth. The studies that focused in Developed countries are limited. This study extends the analysis by comparing the saving determination in Developed and Developing European countries and contributes to the literature of saving in two ways. First, the study compares the two panel groups, Developed and Developing European countries, which might reveal how economic development could affect the saving behavior. Second, the study considers the cross-section dependency effect in the panel data analysis by applying the testing (second-generation panel unit-root and cointegration tests) and the estimation approaches (Augmented Mean Group, AMG estimator). The study demonstrates that ignoring the cross-section dependency effect might lead to misleading results. Four determinants of savings are examined (GDP per capita, age dependency ratio on working group, inflation and government expenditure). Our results reveal the existence of cointegration and cross-section dependency in the saving relationship in both panel groups. Comparing the results across panel groups, it is observed that government expenditure is contributes to lower saving in both groups of countries with larger impact in the Developed European countries. On the other hand, GDP contributes to higher saving in both groups of countries. Inflation also leads to higher saving in the Developed group but not in the Developing group.   Age dependency ratio is not influential in the Developed group but might trigger lower saving in the Developing group.
Hat törvényhatósági jogú város székházépítési pályázata •

A magyar nagyvárosok városházái – amelyek többsége a magyar historizmus legszebb építészeti emlékei közé tartozik – jól reprezentálják azt a robbanásszerű polgárosodást és modernizációt, amely az Osztrák– Magyar Monarchia (1867) létrejöttével bekövetkező változások velejárója volt.

Tanulmányunkban a korszak építészeti tendenciáinak megismeréséhez kívánunk egy új szempontot adni: a nagy városházák térszervezetét vizsgáljuk meg a közigazgatási struktúra történeti alakulásának fényében. Ezzel az elemzéssel egyúttal az adminisztráció és az építészet sajátos viszonyrendszerét is megvilágítjuk.

A vizsgálat alapját a dualizmus korának magyar építészeti szaksajtójában közölt hat törvényhatósági jogú város részletesebb pályázati dokumentációja adja, amely látványosan tükrözi a korszak városháza- építészeti tendenciáit. Győr (1893–1894), Pécs (1902–1903), Marosvásárhely (1905), Szabadka (1906), Pozsony (1907) és Kolozsvár (1910) városi székházainak tervpályázati anyagát dolgoztuk fel, aminek köszönhetően a városháza mint jelentős közigazgatási épülettípust elemeztük az építészeti funkció és a hely igény relációjában. Így – a legnagyobb városházák pályázatain keresztül – a kor városházáinak mint adminisztratív épületeknek – ismert építészeti reprezentativitása mellett – alaprajzi rendszerükben, helyiség struktúrájukban megfigyelhető speciális vonásait rajzolhatjuk fel.

The city halls of the Hungarian large cities – most of which are among the most beautiful architectural monuments of Hungarian historicism – well represent the explosive civilization and modernization that accompanied the changes that took place with the establishment of the Austro–Hungarian Monarchy (1867).

In our study, we want to give a new perspective to get to know the architectural tendencies of the period: we examine the spatial organization of large city halls in the light of the historical development of the administrative structure. With this analysis, we also shed light on the specific system of relations between administration and architecture.

The study is based on the more detailed tender documentation of six cities with municipal rights published in the Hungarian architectural press of the age of dualism, which spectacularly reflects the city hall architectural tendencies of the period.

We wrote up the design competition material of the city headquarters of Győr (1893–1894), Pécs (1902– 1903), Târgu Mureş (1905), Subotica (1906), Bratislava (1907) and Cluj-Napoca (1910), thanks to which we analyzed the city hall as a significant administrative building type in relation to architectural function and space requirements. Thus, through the tenders of the largest city halls, we can draw the special features of the city halls of the age as administrative buildings, in addition to their well-known architectural representativeness, in their floor plan system and room structure.
DISCRIMINATIVE DICTIONARY PAIR LEARNING FOR IMAGE CLASSIFICATION

Published: June 2021

Dictionary learning (DL) for sparse coding has been widely applied in the field of computer vision. Many DL approaches have been developed recently to solve pattern classification problems and have achieved promising performance. In this paper, to improve the discriminability of the popular dictionary pair learning (DPL) algorithm, we propose a new method called discriminative dictionary pair learning (DDPL) for image classification. To achieve the goal of signal representation and discrimination, we impose the incoherence constraints on the synthesis dictionary and the low-rank regularization on the analysis dictionary. The DDPL method ensures that the learned dictionary has the powerful discriminative ability and the signals are more separable after coding. We evaluate the proposed method on benchmark image databases in comparison with existing DL methods. The experimental results demonstrate that our method outperforms many recently proposed dictionary learning approaches.
GRAPH BASED CLUSTERING WITH CONSTRAINTS AND ACTIVE LEARNING

Published: June 2021

During the past few years, semi-supervised clustering has emerged as a new interesting direction in machine learning research. In a semi-supervised clustering algorithm, the clustering results can be significantly improved by using side information, which is available or collected from users. There are two main kinds of side information that can be learned in semi-supervised clustering algorithms: the class labels - called seeds or the pairwise constraints. The first semi-supervised clustering was introduced in 2000, and since that, many algorithms have been presented in literature. However, it is not easy to use both types of side information in the same algorithm. To address the problem, this paper proposes a semi-supervised graph based clustering algorithm that tries to use seeds and constraints in the clustering process, called MCSSGC. Moreover, we introduces a simple but efficient active learning method to collect the constraints that can boost the performance of MCSSGC, named KMMFFQS. In order to verify effectiveness of the proposed algorithm, we conducted a series of experiments not only on real data sets from UCI, but also on a document data set applied in an Information Extraction of Vietnamese documents. These obtained results show that the proposed algorithm can significantly improve the clustering process compared to some recent algorithms.
ADALET AĞAOĞLU’NUN 12 MART DÖNEMİ ÖYKÜLERİNDE SUÇ KAVRAMI
Authors: DİCLE Esra
Published: June 2021

Adalet Ağaoğlu, özellikle 1970’lerde yazdığı öykü, tiyatro oyunu ve romanlarında, 12 Mart döneminin politik ortamına, psikolojik-fiziksel şiddet olaylarına, toplumsal çatışmaya, kutuplaşmaya, işkence gerçeğine, sosyalist öznenin bütün bunlar arasında yaşadığı suçluluk duygusuna, iç ve dış çelişkilere odaklanır. Adalet Ağaoğlu, bu dönemde yazdığı öykülerinde, suç olgusunu, kanunları belirleyenlerin meşruiyetini tartışmaya açar, kanunlar tarafından suçlu ilan edilenlerin masumiyetini sergiler. Bu dönemde yazdığı Yüksek Gerilim (1974) kitabında, 12 Mart dönemi askerî yönetimiyle devrimci aktivistler arasındaki çatışma yansıtılırken aynı zamanda kapitalist-burjuva devletinde işçi-emekçilerin yaşadığı ekonomik şiddet ve onları suça iten koşullar da ele alınır. Böylece hem politik hem adi suç tanımlamaları etrafında suç olgusunun sınıfsal bağlamı sorgulanır. Sessizliğin İlk Sesi (1978) öykü kitabındaysa, 12 Mart döneminin sıcak-çatışmalı ortamından uzaklaşılmasının da etkisiyle yazar, suç olgusunu daha örtük bir bağlamda, ağırlıklı olarak sivil yaşamdaki sınıf çatışmaları odağında ele alır. Bu yazıda, Adalet Ağaoğlu’nun iki öykü kitabında, suç konusuna hangi meseleler odağında yaklaştığını ele almaya çalışacağım.

L’objectif de notre intervention est de rendre compte de l’expérimentation du dispositif d’évaluation SELF FLE conçu dans le cadre du projet IDEFI Innovalangues. Cette expérimentation menée à l’université Ca’ Foscari de Venise en février 2019 concerne environ 100 étudiants répartis en deux groupes correspondant à deux cursus différents (Département d’économie et Département d’études de l’Asie et de l’Afrique Méditerranéenne). Notre intention est de dégager, à partir des résultats obtenus, un lien fort entre l’évaluation à visée diagnostique et formative et la prise en compte, dans les pratiques d’enseignement/apprentissage, de principes clés pouvant guider l’innovation, en tenant compte non seulement du seul niveau de compétence en langue des candidats, mais aussi des leurs profils langagiers (culture d’appartenance, vécu langagier, biographie). Nous entendons analyser les résultats obtenus dans le contexte universitaire italien en les comparant aux résultats obtenus lors des expérimentations effectuées en France, en dégageant des éléments saillants qui permettent d’envisager des innovations dans les pratiques.
