thin films were deposited by radio frequency magnetron sputtering on (100) Si. Rutherford backscattering spectrometry and x-ray reflectivity were used to establish the elemental composition, deposition rate, and mass density. Using the Debye model, the thermal conductivity is extracted from fitted phase velocities measured by surface Brillouin scattering. The low thermal conductivity is revealed to be suitable for Joule heating.

Authors: Imaki Masaharu , Tanaka Hisamichi , Hirosawa Kenichi , Yanagisawa Takayuki , Kameyama Shumpei
Published: August 2020

The 1.53-µm coherent differential absorption lidar (DIAL) is demonstrated for the simultaneous profiling of water vapor (H2O) density and wind speed. The optical setup is fiber-based. The wavelength locking circuit can achieve precise locking of 13.0 MHz by the combination of the line center locking to the hydrogen cyanide (HCN) absorption line and offset locking to the H2O absorption wavelength. The measurable range for the simultaneous profiling is up to 1.2 km. The DIAL-measured H2O density is compared with the one measured by an in-situ sensor. Qualitative good agreement is shown with the random error of 0.56 g/m3.

Authors: Tani Shuntaro , Aoyagi Yutsuki , Kobayashi Yohei
Published: August 2020

We propose a method to monitor the progress of laser processing using laser speckle patterns. Laser grooving and percussion drilling were performed using femtosecond laser pulses. The speckle patterns from a processing point were monitored with a high-speed camera and analyzed with a deep neural network. The deep neural network enabled us to extract multiple information from the speckle pattern without a need for analytical formulation. The trained neural network was able to predict the ablation depth with an uncertainty of 2 μm, as well as the material under processing, which will be useful for composite material processing.
Picometer wavefront sensing using the phase-contrast technique
Authors: Steeves John , Wallace J. Kent , Kettenbeil Christian , Jewell Jeffrey
Published: August 2020

Precision wavefront sensing and interferometry are essential in many
fields of industry and fundamental research. Characterization of
semiconductor devices, optics in lithography systems, and biologic
features of living cells all require measurement resolution at the
nanometer level. The field of high-contrast imaging in space-based
astronomy has pushed wavefront sensing requirements to a new regime
with current and future concepts requiring sensitivity on the order of
10 pm. Techniques to achieve this level of precision have been
demonstrated, but require large, expensive instrumentation with custom
light sources, and therefore do not provide a solution for in-space
operation. Here we demonstrate experimentally the ability to detect
picometer-level wavefront errors at spatial frequencies limited only
by the pixel count of the sampling detector using a simple,
inexpensive method. The system is based on the Zernike wavefront
sensor (ZWFS) that implements the phase-contrast technique whereby the
DC portion of an optical wavefront is phase-shifted with respect to
its higher spatial frequency components. In our demonstration, a
highly repeatable deformable mirror is used to introduce phase
variations into an optical path. We readily sense 60 pm RMS changes in
wavefront errors with the ZWFS system with measurement repeatability
on the order of 0.6 pm. This technique is an enabling technology for
future astronomy missions; however, there are widespread applications
to many other fields requiring high-precision interferometry.
Experimental observations of bright dissipative cavity solitons and their collapsed snaking in a Kerr resonator with normal dispersion driving
Authors: Li Zongda , Xu Yiqing , Coen Stéphane , Murdoch Stuart G. , Erkintalo Miro
Published: August 2020

Driven Kerr nonlinear optical resonators can sustain localized structures known as dissipative Kerr cavity solitons, which have recently attracted significant attention as the temporal counterparts of microresonator optical frequency combs. While conventional wisdom asserts that bright cavity solitons can only exist when driving in the region of anomalous dispersion, recent theoretical studies have predicted that higher-order dispersion can fundamentally alter the situation, enabling bright localized structures even under conditions of normal dispersion driving. Here we demonstrate a flexible optical fiber ring resonator platform that offers unprecedented control over dispersion conditions, and we report on the first experimental observations of bright localized structures that are fundamentally enabled by higher-order dispersion. In broad agreement with past theoretical predictions, we find that several distinct bright structures can coexist for the same parameters, and we observe experimental evidence of their collapsed snaking bifurcation structure. Our results also elucidate the physical mechanisms that underpin the bright structures, highlighting the key role of spectral recoil due to dispersive wave emission. In addition to enabling direct experimental verifications of a number of theoretical predictions, we show that the ability to judiciously control the dispersion conditions offers a novel route for ultrashort pulse generation: the bright structures circulating in our resonator correspond to pulses of light as short as 230 fs—the record for a passive all-fiber ring resonator. We envisage that our work will stimulate further fundamental studies on the impact of higher-order dispersion on Kerr cavity dynamics, as well as guide the development of novel ultrashort pulse sources and dispersion-engineered microresonator frequency combs.
Infrared nanospectroscopy and nanoimaging of individual cell membranes and microvesicles exposed to air
Authors: Eleonora Temperini Maria , Giliberti Valeria , Polito Raffaella , Baldassarre Leonetta , Ortolani Michele
Published: August 2020

We use mid-infrared laser absorption nanospectroscopy and nanoimaging, assisted by atomic force microscopy, to study individual hundred-nanometer-sized cell-membrane patches and microvesicles loaded with proteins. The patches and the microvesicles were sparsely deposited on flat gold surfaces and exposed to air for up to 48 hours. The viability of the transmembrane protein Channelrhodopsin, contained in individual membrane patches with lateral size of 500 nm and thickness of 7 nm, was verified by absorption-difference nanospectroscopy. The physical integrity of spherical microvesicles, produced by mouse cell cultures, of diameters distributed around 160 nm was observed by nanoimaging performed 24 hours after drop-casting. The protein cargo of an individual microvesicle was identified by the acquisition of the local infrared absorption spectrum both immediately after deposition and again 24 hours after deposition. The results suggest that infrared nanospectroscopy and nanoimaging may be regarded as potentially useful techniques to assess the stability of e.g. individual hundred-nanometer-sized virus particles deposited on solid surfaces exposed to air for many hours.
Estimating the Dimension of the Subfield Subcodes of Hermitian Codes
Authors: Nagy Gábor Péter , El Khalfaoui Sabira
Published: August 2020

In this paper, we study the behavior of the true dimension of the subfield subcodes of Hermitian codes. Our motivation is to use these classes of linear codes to improve the parameters of the McEliece cryptosystem, suchas key size and security level. The McEliece scheme is one of the promising alternative cryptographic schemes to the current public key schemes since in the last four decades, they resisted all known quantum computing attacks. By computing and analyzing a data collection of true dimensions of subfield subcodes, we concluded that they can be estimated by the extreme value distribution function.

A infecção hospitalar ocorre por meio da veiculação de microrganismos a um sítio de proliferação orgânico depois de 24 horas da internação hospitalar de um paciente de modo a gerar consequências patológicas e repercutir em um grave problema de saúde pública. O presente estudo objetivou identificar o perfil do conhecimento de enfermeiros assistenciais sobre ações de prevenção e controle de infecções hospitalares. Trata-se de um estudo descritivo, exploratório, com abordagem quantitativa, realizado com 23 enfermeiros assistenciais de um hospital universitário norte mineiro. Utilizou-se um questionário estruturado como instrumento de coleta de dados. O tratamento dos dados se deu por meio de epidemiologia descritiva com estatística não paramétrica. Observou-se prevalência de adultos jovens com idade entre 20–29 anos, do gênero feminino, apresentava pouca experiência no mercado de trabalho com tempo de atuação entre 0–4 anos. Quanto à participação em curso ou treinamento, 65,3% participou. Destes, 33,4% apresentava tempo de participação de 1–5 meses. Com relação à percepção sobre as infecções hospitalares, seus sítios de contaminação, as precauções padrão e suas vias de transmissibilidade, os participantes apresentaram uma média percentual de desconhecimento de 36,3% tornando-se insatisfatória. Portanto, evidenciou-se um baixo nível de conhecimento entre os enfermeiros sendo necessária a programação de novos treinamentos, cursos e disponibilização de educação continuada de modo a contribuir na adoção de medidas de prevenção e controle de infecções hospitalares.
Endoscopic Management of the Ascending Colon Perforation Secondary to a Rare-Earth Magnets Ingestion in a Pediatric Patient
Authors: Camacho-Gomez Sandra Mabel , Noel James Meredith , Noel Robert Adam
Published: August 2020

Rare magnets (neodymium magnets) are high-powered magnets known to cause intestinal perforation if the intestinal mucosa is trapped in between 2 or several magnets. A bowel perforation in pediatric patients secondary to magnets is usually managed with a surgical intervention that might require enterectomy. We report a case of an 11-year-old boy who presented with abdominal pain and a finding on abdominal x-ray of radiopaque foreign bodies located in the ascending colon. He underwent colonoscopy with a finding of embedded magnets with a colonic perforation. The colonoscopy revealed embedded magnets in the colonic mucosa that were colonoscopically removed, and then, the perforated site was successfully managed with endoclipping of the perforation site in the ascending colon.
Doxycycline-Induced Autoimmune Hepatitis
Authors: Pan Jason Jeng , Promrat Kittichai
Published: August 2020

Doxycycline and minocycline are tetracyclines with the potential to cause hepatoxicity. Although autoimmune-like hepatitis from minocycline is well-described, doxycycline-induced autoimmune hepatitis (DIAH) has only been described once. We report a rare case of DIAH with elevated liver enzymes over 5 times the normal upper limit, elevated immunoglobulin G, and high titers of antismooth muscle antibody and antinuclear antibody. By stopping doxycycline, our patient's liver enzymes normalized and immunoglobulin G and autoantibody titers rapidly downtrended. As long-term doxycycline therapy becomes more prevalent to treat acne vulgaris and other skin conditions, DIAH may become more prevalent and recognized.

Published: August 2020

Better understanding of the range of opportunities that can be leveraged from the sustainable and inclusive management of sanitation services is required, alongside the evidence to support it. The Sustainable Development Goals (SDGs) provide a comprehensive framework for sustainable development broken down into 169 Targets articulated under 17 interconnected Goals. Based on a methodology developed at University College London (UCL), this study identifies linkages between sanitation and each of the 169 Targets on the basis of published evidence. We show that there are synergies between sanitation and 130 (77%) of the Targets and trade-offs for 28 (17%) of the Targets. With synergies with all the 17 Goals we identified 83 Targets (49%) that call for action in the sanitation sector. The results demonstrate the far-reaching benefits that can be unlocked from investment in sanitation, which extend beyond health and spread across sectors. This seeks to provide the evidence base to inform strategic investment in sanitation and particularly by integrating sanitation interventions into collaborative cross-sectoral development efforts. The research provides different stakeholders, including policymakers, funders, practitioners and researchers, with a framework that can be applied to context specific cases and projects. We propose a range of recommendations to policy-makers, practitioners, and researchers who seek to take this study further to support delivery of sustainable and inclusive sanitation services for all.
Hacia una comprensión fenomenológica del discurso literario
Authors: Rodríguez Vergara Mauricio
Published: August 2020

ESte artículo es una reflexión sobre algunos aspectos de la interpretación del texto literario. Bajo esta intención, es necesaria una metodología en la que esté involucrado el sujeto y su experiencia de vivida. Esto implica que antes que seguir unos parámetros fijos se le conceda al lector una forma de apropiarse del texto. De esta forma, es el sujeto quien, según su horizonte de experiencia, constituye el sentido del texto. Pero esto no quiere decir que la lectura esté al libre arbitrio del lector, pues obviamente éste deberá seguir ciertos lineamientos interpretativos proporcionados por el mismo autor. Para esto, el sujeto-lector tomará una actitud en la lengua que ponga entre paréntesis lo dicho por una 'ciencia' interpretativa y así se hallará ante el sentido de la obra literaria, la obra de arte o el texto filosófico. Precisamente , la actitud fenomenológica consiste en este poner entre paréntesis; desde esta actitud el lector aprende a ver un texto en su génesis, esto significa reconocer que dicho texto, en particular dicha obra literaria, le invita a poner en acción sus esquemas.

Published: August 2020

Food security and job creation are among the top priorities of the government of Eswatini. To address these priorities, the government have made substantial amount of investment to support the agricultural sector over the years. Regardless of these policy intervention, Eswatini is still an importer of food and unemployment remains substantial high. The study examined the influence of investment climate on productivity of food and beverages industries in Eswatini. Findings of this study will assist the government of Eswatini to design focused policy interventions in order to attract more local and foreign direct investment.A Cobb-Douglas production function for Eswatini of manufacturing industries was estimated using 2006 cross sectional data from the World Bank to produce a measure of TFP for each industry. In addition, an extended Cobb-Douglas production function was estimated with investment climate variables for selected manufacturing industries.The results showed that manufacturing industries in Eswatini are labour intensive and competition from informal sectors is the main obstacle faced by manufacturing industries in Eswatini. The findings of the study further reveals that an increase in corruption  cause a decrease in productivity. The study recommends investment in institutional reforms especially to fight against corruption and efficacy in the provision of public goods and services. It further recommends a resilient support and regulation of the informal sector.

The objective of this study is to examine the effect of entrepreneurial self efficacy on entrepreneurial success. 9,450 small and medium enterprises (SMEs) who are registered members of the National Association of Small and Medium Enterprises (NASME), National Association of Small Scale Industrialists (NASSI) and Association of Small Business Owners in Nigeria (ASBON) in Lagos State is the sample population. Probability sampling technique, specifically, proportionate stratified random sampling method was used to select samples from the sampling frame. The formula developed by the National Education Association (1960) was used to determine the sample size of 381 was used for this study. Primary data on the dependent variable (Entrepreneurial success) and independent variable (Entrepreneurial orientation) was collected using questionnaire as research instrument. Entrepreneurial self efficacy measures are optimism and overconfidence while measures for entrepreneurial success are profitability, market share, net asset growth, sales growth and government policies. The questionnaire was pretested by a pilot study of 50 selected SMEs. Data obtained from the pilot study was analyzed and based on the result, the questionnaire was slightly modified giving an overall Cronbach’s Alpha value of 0.853. The statistics of the model summary of the correlation co-efficient reveal that: R = .232 showing that the combined influence of the two predictor variables had a moderate positive relationship with entrepreneurial success. The coefficient of determination R square is .054 or 5.4%. This suggests that the combined influence of the predictor variables (optimism and overconfidence) explains 5.4% of the variations in entrepreneurial success of SMEs. The value of F (2,207) = 5.866, p <.05, shows that the combined effect of optimism and overconfidence was statistically significant in explaining changes in entrepreneurial success of SMEs in Lagos State. This is established by a p value of 0.003 which is less than the acceptance critical value of 0.05. The findings of the study reveal that entrepreneurs’ optimism had the highest influence on entrepreneurial success because the p value was 0.040 and then entrepreneurs’ overconfidence with 0.201. These findings may be of help to the owner/managers of SMEs to be more entrepreneurial optimistic in order for them to survive the intensely competitive market environment.
Non-performing loans in the hotel industry: The case of Greece
Authors: Dr. Kasimati Evangelia , Kapralou Nuriya , Kyriakopoulou Panagiota
Published: August 2020

Throughout the Greek economic crisis, the problem of rising stock of non-performing loans (NPLs)[1] gradually evolved into one of the most challenging structural deficiencies faced by the Greek banking sector. Despite outstanding performance of the Greek tourism sector, which over the last five years attracted record number of tourists each year, NPLs in the hotel sector remain widespread. The objective of this study is to identify macroeconomic factors and sector-specific characteristics, which led to NPL stock piling in Greek tourism sector. Our findings are supported by rare dataset on NPLs in Greek hospitality sector compiled from publicly available sources. We apply descriptive quantitative analysis to the data from the Bank of Greece, the Hellenic Statistical Authority and other official sources. We found that, despite the record performance of the Greek tourism sector, hotel loans are as problematic as loans issued to other sectors of the Greek economy. Our findings contribute to the NPL literature by providing valuable insights for the Greek hotel industry’s NPL stock, especially in view of the fact that such academic research has not been conducted before.

 

[1]The term ‘NPLs’ is used as a shorthand term to denote all Non-Performing Exposures (NPEs) (ECB, 2017).When a customer delays payment of a loan that is subject to a specific contract with a bank for more than a predetermined number of days then this is considered NPL. Depending on the country, bank, and applicable provisions, the number of days may refer to more than 30, 60 or 90 days (IMF, 2011). The European Supervisory Authorities consider a loan as non-performing when the borrower has been late for more than 90 days to pay the agreed installments to the financial institution that has contracted the contract. According to the European Central Bank (2016), loans repaid by the borrower within the agreed term are considered to be "serviced". Due to the fact that the definition of NPLs is based on a variety of different interpretations, the European Banking Authority attempted to give a single definition through the term ‘NPEs’. NPEs include not only loans but all debt instruments (loans, advances and debt securities) as well as off-balance sheet exposures. NPEs include either of the two criteria:

- Long-term openings that have exceeded the 90-day limit,

- "Uncertainty collection" exposures qualifying as non-serving, although they are either current or have a delay of less than 90 days.

Published: August 2020

The study of firms’ competitiveness has drawn so much attention among business practitioners and academic researchers in the last two decades as globalization came fully into limelight. However, in Nigeria, there are few empirical studies conducted to investigate the relationship between firms’ competitiveness and firm performance.

Thus, the main objective of this study was to provide further evidence on the effects of Firms’ Competitiveness (FC) on the performance of manufacturing firms in Nigeria. Ten large-scale quoted manufacturing firms were selected. The study relied on primary data which were obtained using structured questionnaire administered to 300 purposively selected respondents of the selected firms. The data collected was analysed using Chi-Square Analysis and correlation analysis as well as descriptive analysis in pursuance of the stated specific objectives of the study. The result showed that firms’ competitiveness had significant effects on the profitability and operational performance of the selected manufacturing firms.

Also, firms’ competitiveness had positive relationship with the level of competition of the firms. This study concluded that the practice of firms’ competitiveness is sine qua non in boosting firm performance in the manufacturing firms in Nigeria.
S. Industrial Clusters in Al-Hassan Industrial Estate Study in Economic Geography
Authors: Sababhi Safa
Published: August 2020

The industrial estates represent the most prominent forms of support provided by the state to the industrial sector by achieving external savings that support the establishment and continuation of industries. The successive Jordanian governments seek to support the industrial sector and provide it with all forms of incentives in order to improve the growth of the Jordanian economy and providing job opportunities. Therefore, they established (6) industrial estates distributed all over the Kingdom’s governorates. However, these industrial clusters are still working within the classic classical conception of clustering, as a place for grouping industries, and were unable to switch to the concept of industrial clusters resulting from interaction and integration between industries, while the industrial clusters turned to be a development strategy leading to the growth and development of industries. So, this study aimed to find out if the industries in the Industrial City of Al-Hassan Industrial Estate managed to shift from the traditional concept of clustering to the concept of cluster, and to know the reasons preventing this transformation. The study adopted the descriptive analytical approach and the qualitative analysis of the data collected through the study tool (the questionnaire). The study concluded that the industries in Al-Hassan Industrial Estate were unable to transform into a cluster based on interaction and exchange, and the interaction between factories and the local community represented by academic institutions is at its lowest levels. Therefore, the study recommends restructuring the industrial estates and technology areas in the Kingdom to shift from the traditional role of the industrial cluster to the modern concept.

The Covid-19 pandemic has negatively affected human life. Indonesia Government issued policy on SFH (Study from Home) to respond this situation. This research tried to find out the effectiveness of implementation of that policy on the students both in state and private Junior High Schools (SMP), Senior High Schools (SMA), and Vocational High Schools (SMK). Data was collected from the distributed closed-ended and open-ended questions to 180 students in City of Serang, Banten Province, Indonesia. The scores ranged from minimum 1.00 as Very Poor and 5.00 as Very Good. The implementation of SFH resulted Mean score 2.7911, which was in Fair category. The independent T-Test with probability value 0.05 showed that there were no differences on performances of the school groups, except between the Junior High School (SMP) and Senior High School (SMA) with Vocational High School (SMK). The dominant problems were less various learning design, non-interactive learning, too much assignment, less optimum learning on practical courses for students of Vocational School, less experienced teacher in distance learning, less assistance by parents, and cost for using social media. To sum up, distance-learning SFH was not effectively executed for there were technical problems related to the unpreparedness of the stakeholders, including the government. It is recommended that the implementation of SFH is made lesson learned as the input to design the education providence in new normal era including methods, management, and funding.

Published: August 2020

The researchers investigated the effects of Demonstrative and Guided Discovery teaching strategies on Senior Secondary School Two (2) students’ achievement in Oral English in Bayelsa State. A quasi-experimental design approach was adopted, using a sample of Sixty (60) students comprising of both male and female from Yenagoa Local Government Area of Bayelsa State. Data collated were analyzed using mean standard deviation and the Analysis of Covariance (ANCOVA). This research was guided by Four (4) research questions and hypothesis. The instrument used for data collection was the Oral English achievement test (OEAT), The instrument contained 25 multiple choice items marked over 100 which were standardized. KR20 was used to determine a reliability coefficient of 0.95. The test was based on human sound system. The result analyzed showed among others that there was a significant difference (P=0.000<0.05) between demonstrative and discovery, and demonstrative and conventional methods of teaching. On the other hand, no significant difference existed (p=0.314>0.05) between discovery and conventional method of teaching. The significance difference observed between the various teaching methods is indicative that the demonstrative method is the most effective in the teaching of Oral English. Some recommendations were made on enhancing Oral English language skill acquisition such as provision of e-learning facilities in schools, continuous education for Oral English teachers among others.
Livelihood Strategy Based On Assets As Efforts To Establish Scavenger Empowerment In Facing The Poverty Of Living In The City
Authors: Mahendrawati Ita Kusuma , Prasetijowati Tri
Published: August 2020

Surabaya as the second largest city in Indonesia has its large scale Final Disposal Site (FDS) in Njawar. There are quite a lot of scavengers in this area. They live in a village not far from the landfill site - FDS. Unfortunately, the Surabaya city government has already extended the waste management to the private sector leading to an impact on the income of the scavengers there. On the other hand, the human resources are very minimal. In responding such a situation, the scavengers apply the  livelihood  strategy to empower themselves to survive amid the urban poverty. This study aims to determine the livelihood strategy undertaken by the scavengers in building their empowerment in Surabaya landfill and some factors affecting it. The livelihood strategy  consists of  acquisition, allocation and social networking. Also  the community applies the livelihood strategy for the assets owned comprising of  physical, financial, social, waste, and spiritual assets,  In addition, the results of research indicated that work ethic, work motivation, the role of the collectors as mediators,  facilitators and  patrons have a significant influence on the livelihood strategies undertaken by the scavengers .

The job as a scavenger can be classified as a profession although  this type of profession has not been recognized by the state. Such a condition like this  leads to less government participation in the scavenging community. The result of the study recommended the involvement of the related agencies such as  Social Service, Office of Sanitation and Gardening, NGOs and Universities to  issue  a policy  to regulate all the necessary things in finding out the matters of the scavengers. The participation of the governments of the native cities of the scavengers is highly expected. Some employments are supposed to be provided by their hometown so as to reduce the flow of urbanization

The characteristics of Chinese cultural psychology, such as unremitting self-improvement, social commitment, people-oriented thoughts, collectivism, positive attribution and self-reflection, responsibility and dedication, etc, have provided spiritual support and inexhaustible power for China to overcome this disease. It is the reasons that we should further enhance our cultural confidence, vigorously carry forward and develop China's fine traditional culture, and actively carry out Chinese cultural psychological education.
Strategie chroniące ego – analiza motywacyjna na przykładzie self-handicapping i defensive pessimism
Authors: Więckowska Aleksandra
Published: August 2020

In traditional classrooms, where students are evaluated on the basis of their actions, poor performance is closely linked to the lack of ability. Many students often see failure as a threat to their positive self-image and instead of increasing efforts, apply various ego-protective strategies to shift attention from real or hypothesized lack of ability to other factors influencing unsatisfactory production. In both cases self-worth is protected. This paper aims at performing a motivational analysis of two such strategies, i.e. self-handicapping and defensive pessimism used by secondary school students in achievement context.
Rola ćwiczeń tłumaczeniowych na lekcjach języka obcego
Authors: Kubacki Artur Dariusz
Published: August 2020

The aim of the article is to present the role of translation exercises during foreign language lessons. On the basis of the questionnaire research conducted at a secondary school, the author tries to prove that those scholars who claim that translation exercises should not be used during foreign language lessons are wrong. Although the grammar translation method, which treated translation as a precondition for mastering a foreign language, was harshly criticised, it is now clear that the mother tongue – and hence translation – plays a significant part in the foreign language acquisition process. My empirical research also confirms that teachers often return to translation exercises during foreign language lessons.

Some of the solutions employed in the field of teaching languages for special purposes have turned out to be useful also in the field of general didactics, e.g. the task-oriented approach. What is particularly valuable in the legacy of teaching languages for special purposes is its eclectic nature, which gives one the possibility to choose and combine the best-tested methods depending on the individual characteristics of every learner. Such an undogmatic approach and search for the best possible technique, which takes into account individual characteristics of each student, appears to be a particularly valuable and enriching one in the days of certain reluctance towards an overtly rigidly defined concept of communicative approach in foreign language teaching.

Authors: Basch Corey H. , Hillyer Grace C. , Jaime Christie
Published: August 2020

Objectives

TikTok is a popular social media platform, especially among those who are 13–24 years of age. The purpose of this cross-sectional study was to describe the content of COVID-19 material on TikTok.

Methods

A total of 100 videos posted under the hashtag #Coronavirus were included in this study along with all (n=17) posts uploaded by the World Health Organization (WHO).

Results

Overall, these videos were viewed 1,194,081,700 times. The most commonly cited topics included anxiety (14.5%) with more than 190.6 million views and quarantine (10.3%) with 106.6 million views. Fewer than 10% of videos mentioned how the virus is transmitted, symptoms, and prevention. WHO videos more often focused on viral transmission and symptoms but covered these topics in fewer than 10% of the videos.

Conclusions

Although research suggests that cases of COVID-19 may be less severe in those under 18 years of age, social distancing remains paramount due to the possibility of transmission even in those with minimal or no symptoms. For young adults in particular, the WHO suggests staying connected through social media and making every attempt to stay positive. TikTok has the potential, not only to convey important health information, but to address these aspects of the COVID-19 pandemic as well.

Published: August 2020

Persuasive Weapons: WWI Propaganda Posters is an ongoing digital exhibition and collection hosted by the University of Alabama to commemorate the centennial anniversary of the Armistice signing. This collaborative project distinguishes itself from other publicly available collections by providing detailed compositional interpretations for each poster that situate the images historically and locate salient persuasive strategies. The following Report from the Field chronicles the project’s development, outlines the novel methodological approach, and presents select findings to elevate WWI in public memory, guide future research, and invite adoption of similar approaches to the curation of visual material.
“Unfortunately, Some Mistakes Were Made”
Authors: Salushchev Sergey , Yamboliev Kalina
Published: August 2020

This paper explores competing narratives of the Stalinist and Soviet past in the Republic of Georgia through examination of two public history sites: the Stalin Museum in Gori and the exhibit of the Soviet Occupation at the Georgian National Museum in Tbilisi. While the former remains a site of Stalin’s cult of personality, largely unaltered even during the “de-Stalinization” campaigns that unfolded in the decades following the dictator’s death in 1953, the latter fails to interrogate Stalin’s unambiguous role in the Bolsheviks’ 1921 invasion and political terror amidst its strong emphasis on the martyrs to the Soviet regime. Both museum sites, we argue, are invested in larger scale political and ideological contestations of Georgia’s past in relation to present concerns that anchor, on the one hand, on economic instability and, on the other, on political assertions of Georgian “Europeanness.” The sites raise important questions about the role museums play in the preservation of a contested past and in shaping divergent visions of national memory and identity.

Unemployment can occur due to imbalances in the labor market. This shows that the number of labor forces offered exceeds the number of labor forces requested. The purpose of the study is to analyze factors influencing the unemployment rate: a comparison among five ASEAN countries. This study used quantitative research.  The data collection method in this study is documentation with secondary data since the year 2000-2018. The hypothesis test in this study is done by using Regression analysis and ANOVA with single Classification followed by Post Hoc Analysis. Analysis results analyze factors influencing the unemployment rate: a comparison among ASEAN-5 countries is showed (F=4.599; p<0.002). There is a significant impact of wage, inflation, economic growth and education on unemployment in ASEAN countries. The result found that among the several factors that cause unemployment in a countries the most significant is inflation value is 0.003 < 0.05. While other factors such as wage, economic growth, and education affect but are not significant. Future research should add other variables affecting the unemployment rate.

This study aimed to assess whether there is influence between HDI, GRDP, Unemployment, Investment and Dummy (mainstay and not mainstay areas) on Poverty in Central Java. Based on data from BPS, poverty in Central Java Province in 2013-2018 are in number 2 after DI Yogyakarta in Java. This research use panel data with a Fixed Effect Model (FEM) approach. Sources of data obtained from the Central Statistics Agency and the Directorate General of Indonesian Financial Balance. The results showed that the variable HDI, GRDP and investment had a negative and significant effect on poverty in Central Java Province. While the Unemployment and Dummy variables (mainstay and non-mainstay areas) have a negative and not significant effect on poverty in Central Java Province. Simultaneously, shows that the overall independent variable can show its effect on poverty. The coefficient of determination R2 of 0.9899 which means 98.99 percent of poverty can be explained by the independent variable. While the remaining 1.01 percent is explained by variables outside the model.
PHYSIOTHERAPY FOR CONTROLLING THE COMPENSATORY MECHANISMS AFTER SURGICALLY TREATED COMPLEX ACETABULAR FRACTURES
Authors: Tasheva R.
Published: August 2020

The social relevance of the topic is the opportunity to prevent by physiotherapy the compensations that lead to complications which affect patients' daily lives. The purpose of this study is to present the physiotherapy to control the most common compensatory syndromes, namely "short leg", in patients after surgically treated complex acetabular fractures. METHOD Twenty two patients were operated on surgical stabilized method with reconstructive plates and screws from 2000 to 2019. Pelvis stabilization was achieved by physiotherapy modalities such as unilateral relaxation of hamstrings, erector spinae, multifidus and quadratus lumborum, and their contralateral stimulation. The patients were educated to control pelvis, to flex knee, to strike and rock the heel. RESULTS There were differences between greater trochanter-to-ankle and spina iliaca anterior superior-to-ankle measurements with average 1, 7 cm. Were found the unilateral shorten muscles. The results of the tests were negative at the end of the relative protection phase for 7 procedures. CONCLUSION The social importance of physiotherapy is not only to restore correct and optimal patients, but also to provide prevention of complications after surgically stabilized complex acetabular fractures through avoid the compensatory mechanisms as a “short leg” syndrome.

Published: August 2020

THE AIM OF THIS STUDY is to present the physiotherapy for overcoming the substitution movements and to restore the correct function in the phase of relative protection after surgical stabilized proximal tibia fracture. Material and method Seven patients after fracture in the proximal lateral compartment of the tibia (type b1 in AO classification) with an average age of 42, 9 years were treated. After surgery, an average of 30 days of the brace was used for relative protection. The aim of the physiotherapy was to overcome muscle imbalance to achieve proper movement in the respective planes. Emphasis on recovery was the proper weight bearing on the operated lower limb. RESULTS The results of the first recovery phase demonstrated very limited knee flexion in range of 22, 7º, and knee extension deficit in the range of -15º. After two weeks the results progressed to 115, 5º flexion and full restoration of the extension. Control of edema and hypotrophy of the thigh were proven by circumference. CONCLUSION The adequate physiotherapy provides overcoming of the substitution movements and to restore the correct knee function in the phase of relative protection after surgical stabilized fracture in the proximal tibia.
