It is commonly accepted that using any kind of art in the classroom enhances students' attitudes toward the material and the educational experience as well as their creative abilities, critical thinking skills, and capacity for creative learning. Children who participate in the creative process are better able to understand the world around them via the use of shape, form, space, and movement. Additionally, it inspires creativity and fosters the thrill of unrestricted expression while stimulating one's intellect, psychology, and imagination. It removes the fear of rejection, and promotes involvement, collaboration and sociability. The purpose of this work is to investigate what creativity is, how it connects to art, and to emphasize the value of fostering it in the classroom. When a person thinks outside the box, approaches new areas, and produces novel, exciting outcomes, that person is being creative. The person succeeds in overcoming the habits of habit, absolute logic, and societal pressures, as well as the fear of error and the insecurity of lack of aptitude. Divergent thinking suggests a mind that is active and capable of handling challenges. Therefore, the presence of creative people in contemporary cultures is seen as crucial and vital given the present economic, social, and political circumstances.

In this work we present an updated version of “Safe University”, a protocol aimed to ensure the safe operation of academic institutions during the SARS-CoV-2 pandemic. The protocol is detailed, addressing all aspects of the actions that are required, ranging from controlled access to the university premises and tracking of immunity status to air quality provisions and organization of classes and teaching methods and more. A step-by-step guide and a sample timeline are included, to facilitate practical implementation. The protocol was first developed in the summer of 2021, when the Delta variant had first emerged but not yet dominated, with the aim to support the operation of Greek universities at the beginning of the 2021–2022 academic year. Since then, it has been updated to reflect the evolution of the virus and the pandemic, as well as the developments in the relevant scientific knowledge and additional monitoring, safeguarding and treatment tools that humanity now possesses. It has also been given a more generic form, making it suitable and adjustable for other countries and cultural/political environments as well as other respiratory viruses. With some additional adjustments, it can also be suitable to deal with epidemics from non-respiratory viruses that may arise in the future.

Mass population movements have altered the epidemiology of tinea capitis (TC) in countries receiving refugees. Periodic monitoring of the local pathogen profiles may serve as a basis for both the selection of appropriate empirical antifungal therapy and the implementation of preventive actions. Therefore, we investigated the impact of an unprecedented immigration wave occurring in Greece since 2015 on the epidemiological trends of TC. All microbiologically confirmed TC cases diagnosed during the period 2012–2019 in a referral academic hospital for dermatological disorders in Athens, Greece, were retrospectively reviewed. A total of 583 patients were recorded, where 348 (60%) were male, 547 (94%) were children and 160 (27%) were immigrants from Balkan, Middle Eastern, Asian as well as African countries. The overall annual incidence of TC was 0.49, with a significant increase over the years (p = 0.007). M. canis was the predominant causative agent (74%), followed by T. violaceum (12%), T. tonsurans (7%) and other rare dermatophyte species (7%). M. canis prevalence decreased from 2014 to 2019 (84% to 67%, p = 0.021) in parallel with a three-fold increase in T. violaceum plus T. tonsurans rates (10% to 32%, p = 0.002). An increasing incidence of TC with a shift towards anthropophilic Trichophyton spp. in Greece could be linked to the immigration flows from different socioeconomic backgrounds.

Capturing the image of the shadow cast by the event horizon of an illuminated black hole is, at the most basic level, an experiment of extreme light deflection in a strongly curved spacetime. As such, the properties of an imaged shadow can be used to probe the general relativistic Kerr nature of astrophysical black holes. As an example of this prospect, it is commonly asserted that a shadow can test the validity of the theory's famous `no hair theorem' for the black hole's mass and spin multipole moments. In this paper, we assess this statement by calculating the shadow's equatorial radius in spacetimes with an arbitrary multipolar structure and within a slow rotation approximation. We find that when moments higher than the quadrupole are taken into account, the shadow acquires a high degree of degeneracy as a function of the deviation from the Kerr multipole moments. The results of our analysis suggest that dark objects with strongly non-Kerr multipolar structure could nevertheless produce a Kerr-like shadow with its characteristic quasi-circular shape., Accepted for publication as a Regular Article in Physical Review D

An inadequacy in sanitizing processes in a biopharmaceutical plant in Lanzhou, China, during July and August 2019, led to the aerosolization of Brucella that was subsequently spread through wind to nearby settlements and academic institutes, resulting in >10 000 human brucellosis cases, as of November 2020. The leak, possibly the largest laboratory accident in the history of infectious diseases, underlines the particular characteristics of Brucella that have made the pathogen a historical entity in biodefense research and a major cause of laboratory-associated infections. It further underlines the need for enhanced vigilance and strict regulatory interventions in similar facilities.

We motivate the desire for self-driving and explain its potential and limitations, and explore the need for—and potential implementation of—morals, ethics, and other value systems as complementary “capabilities” to the Deep Technologies behind self-driving. We consider how the incorporation of such systems may drive or slow adoption of high automation within vehicles. First, we explore the role for morals, ethics, and other value systems in self-driving through a representative hypothetical dilemma faced by a self-driving car. Through the lens of engineering, we explain in simple terms common moral and ethical frameworks including utilitarianism, deontology, and virtue ethics before characterizing their relationship to the fundamental algorithms enabling self-driving. The concepts of behavior cloning, state-based modeling, and reinforcement learning are introduced, with some algorithms being more suitable for the implementation of value systems than others. We touch upon the contemporary cross-disciplinary landscape of morals and ethics in self-driving systems from a joint philosophical and technical perspective, and close with considerations for practitioners and the public, particularly as individuals may not appreciate the nuance and complexity of using imperfect information to navigate diverse scenarios and tough-to-quantify value systems, while “typical” software development reduces complex problems to black and white decision-making.

The linguistic and cultural diversity within the European Union has created new demands for multilingual European citizens. To meet the new requirements, it is necessary, educational strategies to be designed by those who actively involved in foreign language education in various countries in a new context, which will ensure the "productivity" of learning foreign languages in the implementation of foreign language education. This effort also includes this paper, which introduces the model of socio-cognitive learning theory in the context of the communicative approach to the teaching and learning of foreign languages. Especially in this case study, the teaching and learning of the idioms Used to and Would Idioms will be presented by using the Sosio-cognitive theory.

Nowadays, many organizations try to ensure the best result with the minimum necessary sources by following the practices of the propulsion of self-valuation throughout the European Foundation for Quality Management (EFQM) approach, within the frame of a Strategic Planning. The self-valuation criterions of the EFQM, can also be implemented in military units. The case of the EFQM self-valuation criterions’ implementation in a military Unit is examined in this study. It is tried a critical analysis of the case, by examining the following practice of its Commander within the context that his activities are emerged. Then, a particular proposal which concerns the implementation of the planning that follows the Johnson and Scholes (1993) model, is presented. The various manifestations and meanings of the self-valuation criterions and the useful tool of the Strategic Planning are revealed. Moreover, the characteristics of the leader-Commander are presented, so that the unit can meet the standards of the desired final state. The demand of active Commanders with vision, who can inspire the personnel by the proper guidance and the ability to convince them to follow the procedures, is the conclusion that comes out of the proposal. By carrying out a continuous self-valuation, within the frame of the EFQM criterions, and then, following the necessary actions, the improvement can be achieved. The personnel and the potential of its progress, the stuff maintenance, the facilities’ improvement, the exploration of the environment, in order recourses can be found, are the crucial factors so that actions can be taken over, which will targer to the exploitation of the unit’s potentials, the reduction of the threats and the weaknesses’ change into potentials. Commanding and leading skills are necessary with the simultaneous participation of all bodies in the various procedures. Yet, unpredictable situations, limitations and moral dilemmas may appear, making thus difficult Strategic Planning’s implementation.

Language is a multidimensional phenomenon in the context of which one might observe lingual differentiation resulting in the appearance of lingual varieties. Factors that can be attributed to the observed lingual differentiation are geographical area, social characteristics of the speakers, communicative situation and the contact / coexistence of languages. Members of each social class create a special cultural subsystem, which, of course, includes language. In addition, there is a direct and not accidental relationship between social stratification of the society and lingual diversity. Social networks with their parameters (density of population and variability), serve as factors influencing formation of language varieties. This article aims to highlight and explain the role of social class and social network in the formation of language varieties. Although the argumentation developed in this paper highlights the importance of two above mentioned factors in shaping lingual differentiation, they alone could not be the only interpretive tools of lingual diversity. Ways of how lingual differentiation happens, mutual impact between social lingual forms and idiolects, especially within certain geographical area, might be the subject for the further research.

On 17th November 2015, a strong earthquake affected the southern part of the Lefkada Island, Greece. After the earthquake extensive translational debris slides triggered cross most of west coast of the island in a distance of about 15 km. The majority of these slides concentrated at Egremni beach which is a famous touristic destination. The cliff is crossed by the Cephalonia Fault Zone and this is considered as a major factor provoking the steep slope, large-scale co-seismic and post-seismic mass wasting and disturbance of the forest of the cliff. Seven years after the 2015 event, the cliff remains at retreat due to limited forestation, seismicity and storms in the area. Monitoring of the cliff was performed between 2015 and 2021 including extensive field measurements, unmanned aerial vehicle (UAV) flight campaigns and a sediment trap. The high-resolution images acquired by the UAV were used for the creation of orthophoto maps and digital surface models (DSMs) of the cliff. The data indicates that Egremni cliff is slowly entering a stage of equilibrium due to climatic forcing, alongside minor seismicity and absence of forestation. Mass-wasting processes remained significant across the Lefkada west coast seven years after the 2015 earthquake sequence.

Congenital abnormalities of the Inferior Vena Cava (IVC) should be suspected in cases of Deep Venous Thrombosis (DVT), especially in young patients, with no other risk factors and apparent causes. Currently, there is no guidance regarding the management of such patients. We report a case of Iliofemoral vein thrombosis in a young patient with congenital absence of the IVC that was successfully treated with catheter-directed thrombolysis (CDT) and perform a systematic review of the literature to identify evidence about the epidemiology, clinical presentation, management, and prognosis of this rare cause of DVT. A total of 42 studies reporting on 56 cases were included in the review. The mean age of the patients at the presentation of their first DVT episode is 23.6 years, 83.9% of patients were males, conservative management with anticoagulation was used in 68% of the reported cases, and thrombolysis was used in 32% of the cases. Only 10.7% of patients presented with PE potentially justified by the abnormal anatomy of the deep veins which makes the propagation of thrombi into the pulmonary arteries less possible. Comparing the long-term outcomes of the two treatment groups; 42.3% of the patients treated conservatively vs 15.4% of the patients treated with thrombolysis developed chronic symptoms (residual heaviness, pain, swelling, and cramping). 11.5% of patients who received conservative treatment developed post-thrombotic syndrome. None of the patients treated with thrombolysis developed post-thrombotic syndrome. There were no procedure-related complications and thrombolysis was well tolerated by the entirety of the thrombolysis treatment group. Recurrence of DVT occurred in 13% of the patients treated conservatively and in 7.7% of patients treated with thrombolysis. Thrombus removal by means of thrombolysis is the recommended treatment and can offer excellent short and long-term results. Anticoagulation with NOACs may be prescribed for life to prevent recurrence or for at least 6 months and then reconsidered following further evaluation of patients' bleeding risk. It may be of value to organise an international registry for such patients. Guidelines issued by the relevant scientific societies will then be able to make a clear recommendation about the management of such patients.

We study variants of the local models constructed by the second author and Zhu and consider corresponding integral models of Shimura varieties of abelian type. We determine all cases of good, resp. of semi-stable, reduction under tame ramification hypotheses.

Language has generally been characterized as a tool of communication between people, the mean by which man expresses his feelings and thoughts. It has been the subject of research from various angles and methodological standards that largely reflect the variety of dimensions from which it can be studied but also the prevailing analysis trends. Language is also seen as a social process, as a way of creating interpersonal relationships and expressing emotions. Therefore, integrated language teaching takes into account the social character of the language and relies on it. The linguistic and cultural diversity within the European Union has created new demands for multilingual European citizens. To meet the new requirements, it is necessary, educational strategies to be designed by those who actively involved in foreign language education in various countries in a new context, which will ensure the “productivity” of learning foreign languages in the implementation of foreign language education. There is an urgent need to promote the process of communicative teaching, so that the student who learns the specific foreign language transmits his own concepts, in the cases, interacting and trying to adapt to the common knowledge and even the linguistic ability of a person that this language is his/her mother tongue. The approach to the service of the communicative type of teaching emphasizes the communicative function of the language and tries to create in the students the opportunities for functional use of the language code, similar to those they will encounter outside the classroom. Students need to connect with each other to build friendly relationships within the classroom that becomes a student community. This effort also includes this paper, which introduces the model of socio-cognitive learning theory in the context of the communicative approach to the teaching and learning of foreign languages.
