Published: April 2021

Abstract
In the 21st century, teachers’ learning is viewed through the lens of sustainable development as a holistic, transformative and collaborative learning process. Acknowledging that teacher professional development is a prerequisite for educational quality, it becomes necessary to look for professional development factors that could be relevant to sustainable professional development. The article explores factors of sustainable professional development of teachers based on data of TALIS 2018 from four Baltic countries (Estonia, Finland, Latvia, and Lithuania). The study also discusses distinct characteristics of teacher professional development in the analyzed countries. Although traditional forms and methods of professional development still prevail in all countries, teachers also learn through active cooperation. Finnish teachers, more often than teachers in the other countries, worked in teams and shared material, knowledge, etc. with each other; Estonian teachers, more so than teachers in the other countries, took part in long-term training; Latvian teachers were more likely than teachers in the other countries to observe other teachers’ classes and provide feedback. Lithuanian teachers were perhaps the most active in terms of learning, but young teachers with fewer years of service were more likely to engage in long-term and collaborative activities. Finally, the implications for further research are discussed.

Abstract

Introduction
Foot-and-mouth disease is a highly infectious viral disease affecting all cloven-footed domestic animals. The three foot-and-mouth disease virus (FMDV) serotypes A, O and SAT2 are at present the greatest threat to susceptible animals in Egypt. The aim of the present study was, for the host factors associated with different FMDV infections in cattle during the acute phase, to compare these factors’ influence on the expression of the IL-10, TLR-2, TNF-α, CXCL10, CD48, NFATC4 and IFNG inflammatory and immune-related genes.

Materials and methods
Vesicular fluid and epithelium samples were obtained from at least three infected cattle on the same affected farm during three different FMDV outbreaks and were used for serotyping of the virus and for expression analysis of host genes. A two-step RT-PCR was used for diagnosis of the virus with primers specific for each serotype.

Results
In quantitative PCR analysis, the expression patterns of TLR-2 and IFNG were prominent, while NFATC4 expression was absent in all FMDV-infected cattle. The highest expression of CD48 was associated with increased expression of other inflammatory and immune-related genes (IL-10, TLR-2, TNF-α and IFNG), which may be an indication of rapid virus clearance.

Conclusion
The use of vesicular fluid and epithelium for investigation of viral and immune-related gene expression levels in acute FMDV infection is possible. Host-dependent variation in the expression of the studied genes was observed in different FMDV serotype outbreaks.
Testing of pilot 2 m3 exposure chamber for formation of brochantite based patina on copper and copper alloys – objects of practical dimensions

Published: April 2021

Abstract
Formation of natural patina on copper and copper alloys objects takes tens of years. There are solutions for patination, which are used in restorers’ practice. However, these artificial patinas are usually based on nitrates, carbonates or chlorides. Patina based on brochantite is the most stable phase under atmospheric conditions. This type of patina was successfully formed in laboratory in a small exposure chamber with higher content of SO2. This work is next step of the experiment to make this method become more practicable. It started with construction 2 m3 exposure chamber and simulation of ideal conditions for patination process. The length of drying phase, homogeneity of conditions, pH of feeding water, colour of patina, placement of samples and final appearance were observed. The chamber construction allows to achieve ideal pH value of feeding water, samples surface became dry during the ventilation and temperature during condensation was stable at 40 °C. These conditions are ideal for patination process.

Abstract
The corrosion inhibition efficiency of the novel pyridine namely, 4-(Benzoimidazole-2-yl)pyridine has been studied for mild steel in a 1 M hydrochloric acid environment by utilizing gravimetrical techniques. The synthesized inhibitor exhibits a significant inhibitive efficiency of 93.8% at 0.005 M. The adsorption isotherm of the investigated inhibitor on mild steel surface obeys the Langmuir isotherm. Surface morphology investigated by utilizing scanning electron microscopy (SEM) demonstrates a smooth metal surface with the addition of 4-(Benzoimidazole-2-yl)pyridine in a hydrochloric acid environment. Quantum chemical calculations using density functional theory (DFT) have been used to investigate the molecular structure and behavior of 4-(Benzoimidazole-2-yl) pyridine as a corrosion inhibitor. Different parameters have been calculated using DFT, such as energies of highest occupied molecular orbital and lowest occupied molecular orbital (EHOMO and ELUMO), energy gap (∆E), and dipole moment (μ). These parameters were important to elucidate the behavior of the investigated molecule as a corrosion inhibitor in acidic solution and also suggest the mechanism of inhibition.

Striving for a restitution of the former splendor? Reasons for municipal splits in Poland
Authors: Łukomska Julita 
Published: April 2021

Abstract
Shaping the administrative division of the country is influenced by various factors. Based on the analysis of 22 municipal divorces in Poland between 1995 and 2019 the article attempts to identify the determinant factors of these splits. The article examines environmental (economic or cultural) and political factors which may stimulate the fragmentation initiatives. The results indicate that in Poland cultural factors appear to be at least as important as economic ones. An argument of great significance in the process of a new municipality creation (both in the case of successful and unsuccessful splits) was the memory of the inhabitants about the time when they were operating as a separate municipality. In case of rural municipalities the existence of a second almost equally important population centre in the municipality was an important factor contributing to the municipal splits.

Published: April 2021

Abstract
The nature of urban and rural accidents has been different from each other in some of the factors and even the severity of damage rate, mayhem, and death. In this research, using statistical methods and binary logistic regression model, we have addressed to analyze important parameters such as age, gender, education level, the color of the pedestrian dress, season of accident, time of accident, the speed of the vehicle colliding with pedestrians and road surface conditions at the time of accident on the way of death (at the scene of the incident or in the hospital) pedestrians who have been traumatized. After the creation of the binary logistic regression model, it was determined that only the parameters of speed and the accident time have been significant in the level less than 5%. And other parameters such as age, gender, the season of accident occurrence, the color of the pedestrian dress, road surface conditions and education level had no significant effect in terms of statistical on the incidence of mortality arising from a pedestrian accident with the motor vehicle. The results revealed that by adopting decisions related to the traffic calming, attention to passages lighting and brightness the mortality rate of a pedestrian due to the urban accidents can be reduced.
The Presence of Real Reality: Six Theses on Dance Animateuring
Authors: Foster Raisa 
Published: April 2021

Abstract
Tanssi-innostaminen® (‘dance animateuring’ in English) is an artistic and pedagogical method, which I have developed in order to empower both individuals and communities. By dance animateuring I refer to dance/ movement based activity, in which everyone can find their own way of moving and expressing by movement, but also reflecting the self and its connections to the other and the whole world. In this paper I will argue the six theses that define my approach to contemporary art making in dance animateuring practice: 1) The dancer should never aim to produce something specific but only to be present. 2) The performance shows that everyone can dance. 3) The performance is born from action, not from an idea. 4) The performance is multisensory and multidisciplinary artwork. 5) The performance is incomplete and ambiguous. 6) The performance challenges the conventional ways of seeing the world and people.

Published: April 2021

Abstract
The relationship between health and physical activity is well documented through research, but we know less about the health effects of cultural activity. The background for this project is a passionate interest in dance in general and especially folk dance. Many questions have emerged such as: What do we know about the connection between dance and health? Can social dance promote health and prevent disease? This article will present folkdance in a physical, psychosocial and cultural view.
Democratic Bodies? Reflections on «Postmodern Dance» in the United States and Finland
Authors: Järvinen Hanna 
Published: April 2021

Abstract
By looking at how ’postmodern dance’ signifies in the dominant American and local Finnish contexts, I offer a critical reading of how the notion of ’democracy’ is intertwined with particular dancing bodies and ideas of nation and ethnicity. This requires a historical outline for how ’democracy’ entered the discourse of dance, and specifically, how its meaning has shifted in relation to the canon of the art form. Using the contrast between the hegemonic centre and what is constituted as a (geographic, linguistic, ethnic) periphery reveals how ’democracy’ is used in contemporary dance discourses to obfuscate power relations inherent to art and its institutions, especially in relation to the agency of dancers.
«Get in Your Theatres; the Street is Not Yours»: The Struggle for the Character of Public Space in Tunisia
Authors: Harrington Heather 
Published: April 2021

Abstract
How people move and appear in public spaces is a reflection of the cultural, religious and socio-political forces in a society. This article, built on an earlier work titled ’Site-Specific Dance: Women in the Middle East’ (2016), addresses the ways in which dance in a public space can support the principles of freedom of expression and gender equality in Tunisia. I explore the character of public space before, during, and after the Arab Spring uprisings. Adopting an ethnographic and phenomenological approach, I focus on the efforts of two Tunisian dancers – Bahri Ben Yahmed (a dancer, choreographer and filmmaker based in Tunis, who has trained in ballet, modern dance and hip hop) and Ahmed Guerfel (a dancer based in Gabès, who has trained in hip hop) – to examine movement in a public space to address political issues facing the society. An analysis of data obtained from Yahmed and Guerfel, including structured interviews, videos, photos, articles and e-mail correspondence, supports the argument that dance performed in public spaces is more effective in shaping the politics of the society than dance performed on the proscenium stage. Definitions and properties of everyday choreography, site and the proscenium stage are analysed, along with examples of site-specific political protest choreography in Egypt, Turkey and Tunisia. I engage with the theories of social scientist Erving Goffman, which propose that a public space can serve as a stage, where people both embody politics and can embody a protest against those politics.
Job Burnout and Counterproductive Work Behaviour of the Jordanian Bank Employees
Authors: Lubbadeh Tareq 
Published: April 2021

Abstract

Background/Purpose: This study investigated the relationship between job burnout and counterproductive work behavior (CWB) among 307 employees drawn from various banks within Jordan. This study also examined the levels of job burnout and CWB with regard to gender, age, marital status, and education.

Methodology: For data collection, the convenience sampling method is utilized to survey frontline bank employees. The Oldenburg Burnout Inventory scale, which assesses exhaustion, disengagement, and the CWB scale from the Individual Work Performance Questionnaire (IWPQ), were used for data collection. The data were analyzed using the Statistical Package for Social Science 25.0.

Results: The study results suggest that there is a significant positive relationship between job burnout two dimensions and CWB. The research also shows that age, education, and marital status affect both job burnout and CWB. Nevertheless, gender was found to have a significant effect only on the disengagement dimension of job burnout. Further, the study implies that exhaustion and disengagement are vital predictors influencing CWB.

Conclusion: With regard to the results, the phenomena of job burnout provide the means that can provoke deviant behavior in the workplace.

Self-esteem of medical students and their attitudes towards the nurse profession
Authors: Gierszon Patrycja , Milanowska Joanna , Łopuszańska Urszula , Sidor Katarzyna , Paziewska Magdalena , Samardakiewicz Marzena 
Published: April 2021

Abstract

Introduction. The profession of a nurse is next to the medical profession, one of the pillars of medical care in Poland and in the world. In recent years, the need to see the importance of this profession and the responsibility associated with it, both by the public and the doctors, is increasingly underlined.

Aim. The research carried out is an attempt to answer the question, what attitudes towards nurses are shaped by future doctors already during the studies and what influence on students’ self-esteem on these attitudes.

Material and methods. The research was conducted among 89 students of the medical faculty, Medical University in Lublin in April 2018. A questionnaire of own authorship was used, constructed on the basis of descriptive research carried out by Maik M. et al and the Rosenberg Self-Assessment Questionnaire (SES). The obtained results were subjected to statistical analysis using the STATISTICA program, version 13.1.

Result. The vast majority of medical students (80%) believe that the role of a nurse is underestimated both in society and in the medical community. Students think that this work requires sacrifice and constant vigilance. Students who have encountered nursing staff notice symptoms of burnout in some of them, such as depersonalization of patients (56%). However, most of them (60%) think that this is ungrateful work and often interferes with family life. Students do not agree that the nurse should always be smiling and optimistic (75%). She values her features such as patience, good organization of time (86%) and ability to cooperate with doctors (91%). Most of students think that a nurse is a partner of a doctor (73%), while almost half (49%) of them see imperfections in cooperation both professional groups, resulting from the lack of mutual respect (64%). Students notice the commitment and hard work performed by nurses (70%), and also, although to a lesser extent, they appreciate their knowledge (56%).

Conclusion. Appreciation of the nurse’s role on the part of doctors seems to be particularly important due to the need for cooperation of medical staff. The quality of cooperation between the interdisciplinary team and, consequently, the quality of care and medical care depends to a large extent on the mutual respect, understanding and correct communication between these professional groups.
“Warn Them” or “Just Block Them”?: Investigating Privacy Concerns Among Older and Working Age Adults
Authors: Ray Hirak , Wolf Flynn , Kuber Ravi , Aviv Adam J. 
Published: April 2021

Abstract
Prior work suggests that older adults are less aware of potential digital privacy risks compared to younger groups. We seek to expand on these findings by using drawmetrics with 20 older adults (60+) to visualize their experiences with digital privacy via drawing sessions. We further compared older adults with 20 adults of working age (18-59) with the goal of identifying both overlapping concerns and key differences that may be missed when viewing each group in isolation. We extended our evaluation with a survey with questions and themes derived from open-coding of the drawn images and confirmed three key differences between the age groups. These include older adults perceiving a greater threat from using online banking and e-commerce compared to working age adults, older adults exhibiting greater levels of concern about global scale threats, and working age adults showing more privacy-related concern regarding social media. Our findings can be used to potentially tailor applications to better accommodate privacy concerns for older adults.
Website Fingerprinting in the Age of QUIC
Authors: Smith Jean-Pierre , Mittal Prateek , Perrig Adrian 
Published: April 2021

Abstract
With the meteoric rise of the QUIC protocol, the supremacy of TCP as the de facto transport protocol underlying web traffic will soon cease. HTTP/3, the next version of the HTTP protocol, will not support TCP. Current website-fingerprinting literature has ignored the introduction of this new protocol to all modern browsers. In this work, we investigate whether classifiers trained in the TCP setting generalise to QUIC traces, whether QUIC is inherently more difficult to fingerprint than TCP, how feature importance changes between these protocols, and how to jointly classify QUIC and TCP traces. Experiments using four state-of-theart website-fingerprinting classifiers and our combined QUIC-TCP dataset of ~117,000 traces show that while QUIC is not inherently more difficult to fingerprint than TCP, TCP-trained classifiers may fail to detect up to 96% of QUIC visits to monitored URLs. Furthermore, classifiers that take advantage of the common information between QUIC and TCP traces for the same URL may outperform ensembles of protocol-specific classifiers in limited data settings.
Defending Against Microphone-Based Attacks with Personalized Noise

Published: April 2021

AbstractVoice-activated commands have become a key feature of popular devices such as smartphones, home assistants, and wearables. For convenience, many people configure their devices to be ‘always on’ and listening for voice commands from the user using a trigger phrase such as “Hey Siri,” “Okay Google,” or “Alexa.” However, false positives for these triggers often result in privacy violations with conversations being inadvertently uploaded to the cloud. In addition, malware that can record one’s conversations remains a signifi-cant threat to privacy. Unlike with cameras, which people can physically obscure and be assured of their privacy, people do not have a way of knowing whether their microphone is indeed off and are left with no tangible defenses against voice based attacks. We envision a general-purpose physical defense that uses a speaker to inject specialized obfuscating ‘babble noise’ into the microphones of devices to protect against automated and human based attacks. We present a comprehensive study of how specially crafted, personalized ‘babble’ noise (‘MyBabble’) can be effective at moderate signal-to-noise ratios and can provide a viable defense against microphone based eavesdropping attacks.

AbstractIn this paper, we address the problem of privacy-preserving distributed learning and the evaluation of machine-learning models by analyzing it in the widespread MapReduce abstraction that we extend with privacy constraints. We designspindle(Scalable Privacy-preservINg Distributed LEarning), the first distributed and privacy-preserving system that covers the complete ML workflow by enabling the execution of a cooperative gradient-descent and the evaluation of the obtained model and by preserving data and model confidentiality in a passive-adversary model with up to N −1 colluding parties.spindleuses multiparty homomorphic encryption to execute parallel high-depth computations on encrypted data without significant overhead. We instantiatespindlefor the training and evaluation of generalized linear models on distributed datasets and show that it is able to accurately (on par with non-secure centrally-trained models) and efficiently (due to a multi-level parallelization of the computations) train models that require a high number of iterations on large input data with thousands of features, distributed among hundreds of data providers. For instance, it trains a logistic-regression model on a dataset of one million samples with 32 features distributed among 160 data providers in less than three minutes.
