Clinical Profiles of Thyroid Dermopathy: A Dermato-Endocrinological Perspective
Authors: Azeez Taoreed Adegoke , Egbu Ayobami Chioma
Published: January 2021

Thyroid disorders sometimes have extra-thyroidal manifestations. Hyperthyroidism is a clinical syndrome resulting from excessive secretion of thyroid hormones. The most common cause is Graves’ disease. About 0.5–4.3% of patients with Graves’ disease have an infiltrative dermopathy called thyroid dermopathy, which is due to excessive deposition of glycosaminoglycans from activated fibroblasts. Skin fibroblasts are activated by thyroid stimulating hormone receptor antibodies the whole process being initiated by T lymphocytes. Rarely, thyroid dermopathy is also found in other thyroid disorders such as Hashimoto thyroiditis. The diffuse non-pitting edema variant is the most common clinical presentation. Other variants include the nodular, plaque, mixed, and elephantiasis types. Usually, the main concerns of the patients are cosmetic, discomfort, and difficulty in wearing shoes. Thyroid dermopathy usually presents after the diagnosis of Graves’ disease, but it may also present together or sometime after this condition. Rarely, thyroid dermopathy presents before the diagnosis of Graves’ disease is made. Apart from the shin and feet, other sites that can be affected include the arms, forearms, back, thighs, pinna, and nose. The management is multidisciplinary, involving dermatologists and endocrinologists. Usually, controlling the thyroid dysfunction does not translate into regression of the skin lesions. However, many patients have their thyroid dermopathy regress spontaneously, while others usually require local therapy. Other therapeutic options include systemic therapy such as pentoxifylline, compressive physiotherapy, and surgery.
Trends in Oncology: an Updated Review of Minimally Invasive Surgery vs. Traditional Open Surgery
Authors: Lee Kyuwon , Wang Ahromi
Published: January 2021

Objective: To review the recent trends in methodology for the most frequent oncological surgeries. More specifically, this paper will compare the minimally invasive methods to the conventional open method. It aims to find out whether minimally invasive surgeries are feasible treatments for certain types of cancers.

Methods: A review of retrospective studies searched in PubMed, Cochrane Library etc. was used to identify the studies published on this topic within a period of 6 years. Oncologic outcomes, postoperative complications/outcomes, and intraoperative outcomes were the main variables in the comparison to the surgical methods under review.

Conclusion: Despite the recent controversy with minimally invasive surgery being contraindicated for cervical cancer, it is still an acceptable method for other types of common cancers. However, there are limitations to the approach, and the surgeon should make a prudent selection between minimally invasive and open surgery depending on the type of tumor and patient characteristics. Further studies, especially with randomized control trials, must be conducted.
Finite element simulation of the impedance response of a vascular segment as a function of changes in electrode configuration
Authors: Amini M. , Kalvøy H. , Martinsen Ø.G.
Published: January 2021

Monitoring a biological tissue as a three dimensional (3D) model is of high importance. Both the measurement technique and the measuring electrode play substantial roles in providing accurate 3D measurements. Bioimpedance spectroscopy has proven to be a noninvasive method providing the possibility of monitoring a 3D construct in a real time manner. On the other hand, advances in electrode fabrication has made it possible to use flexible electrodes with different configurations, which makes 3D measurements possible. However, designing an experimental measurement set-up for monitoring a 3D construct can be costly and time consuming and would require many tissue models. Finite element modeling methods provide a simple alternative for studying the performance of the electrode and the measurement set-up before starting with the experimental measurements. Therefore, in this study we employed the COMSOL Multiphysics finite element modeling method for simulating the effects of changing the electrode configuration on the impedance spectroscopy measurements of a venous segment. For this purpose, the simulations were performed for models with different electrode configurations. The simulation results provided us with the possibility of finding the optimal electrode configuration including the geometry, number and dimensions of the electrodes, which can be later employed in the experimental measurement set-up.
New Public Management as a Tool for Changes in Public Administration
Authors: Stroińska Ewa
Published: January 2021

Objective: The implementation of mechanisms stimulating marketization of the public sector is an elementary assumption of a modern public management system. The main goals of these processes are to increase efficiency, reduce bureaucracy, create a platform for cooperation between public and private entities, and extend decentralization. The set of rules practiced in modern local governments increasingly resembles a private enterprise managed by efficient managers. The traditional approach, which was only the administration process itself, is being replaced by a focus on economy, efficiency, quality, and effectiveness.

Methodology: The material was created based on the qualitative method in the form of secondary analysis of literature data. At the same time, it provides the theoretical background for conducted empirical research on changing the management system in public administration. The effect of further research explorations will be another material presented in the form of a research report

Value Added: The New Public Management (NPM) concept is based on changing the orientation of management of public organizations consisting in ceasing to apply the approach focusing only on procedures and rules of conduct related to expenditure, and implementing rules based on the analysis of the results related to expenditure incurred, adopting strategic orientation and introducing market mechanism for the process of providing public services (Zalewski, 2006, p. 74). The purpose of the article is to describe the New Public Management model, the implementation of which helps public institutions to respond to challenges posed by external and internal stakeholders.

Findings: The article presents the thesis that changes in public administration require the transformation of a management system characterized by entrepreneurship, the use of different business-oriented strategies for implementing effective actions.

Recommendations: The idea of New Public Management is to replace the bureaucratic administrative management model and to introduce a managerial model, i.e. the application in the public sector of the principles and solutions of management systems known and used in the business sector (Alford & Huges, 2008, pp. 130–148). This is caused by the increase in citizens’ expectations regarding the increase in the quality of service provision, while at the same time unwilling to raise taxes. To achieve this goal, NPM has introduced certain assumptions to help in effective management (Templatka, n.d.).

Authors: Sułkowski Łukasz , Dziedzic Justyna
Published: January 2021

Objective: The purpose of this article is to show the diversity of possibilities for interpreting identities in the context of the academic profession by showing the different dimensions of participation in the academic community and personality transformations associated with the capture of certain attitudes and behaviors of the scientists.

Methodology: The article is based on a critical analysis of the literature dealing with the sense of organizational identity in the scientific context. We expanded the characteristics associated with this issue to the recognitions arising from the complexity of participating in the life of science on many levels. The work provides an overview of the research approaches of potential detectable factors shaping the investigator’s personality in organizational terms. Provided a theoretical background on scientist identity in an organizational context in this paper provides the directions of the research that brings diagnosis in management sciences.

Findings: Scientist organizational identity is the concept that provides a few interpretational directions that can be explored in the management context. The empirical views on this subject provide two levels of meaning. On the first level, it raises questions about individual needs related, on the one hand, to the factors of participation in this profession’s life, like prestige, carrier, and power. On the other hand, the second level’s meaning is connected with the scientist’s personality and compatible with his professional choices like scientific orientation on life choices and creative disposition of high professionalism. The multi-mentality of participation, both physical, emotional, and life academism discourse, brings many recognitions of the concept of scientific organizational identity.

Value Added: Attention has been paid to the critical discourse on the theory of an organization’s influence on its scientific members’ identity. Also, an indication of the role of these processes in the power and hierarchy context. In the other context, we try to understand the role of individual human dispositions and professional socialization processes in the academic profession.

Recommendations: Scientists’ organizational identity is an interesting direction to explore, that brings many reflections about the influence that brings the academic profession area to scientific senses of being. These processes also influence factors like bureaucracy, hierarchy, career politics, evaluation processes, and academic organizational narratives.

Simulation of a Motor Vehicle’s Motion on the Basis of a Turning with the Steering Wheel Release
Authors: Zalewski Jarosław
Published: January 2021

In this paper, the selected phenomena related to a motor vehicle’s motion have been considered based on a computer simulation in MSC Adams/Car. The vehicle’s model performed a turning maneuver with the steering wheel release under different road conditions.

All simulations have been performed based on the sports two-seater vehicle’s model, at the initial speed of 70 km/h on the flat and randomly uneven road. This enabled us to observe the selected phenomena along the road long enough to relate them to different aspects of road traffic safety in unusual situations. For uneven road, the same profiles were assumed for the left and the right wheel of the vehicle, with two coefficient values determining the maximum height of these irregularities.

Authors: Fix Marieke , Ritzen Henk , Kuiper Wilmad , Pieters Jules
Published: January 2021

The present study researched teachers’ emotions related to their pedagogical work with disengaged students. The aim of the study was to investigate teachers’ emotions experienced during classroom practice and how emotions were related to their perceived well-being. Based on the literature, we assumed that teachers’ perceived well-being was affected by the emotions in their classroom practice through their feelings of autonomy, competence and relatedness. Data were collected using qualitative methods. In our results, we reported that teachers experienced mixed emotions elicited by interactions with students, student learning, colleagues and the programme. We determined the characteristics of classroom practices that contribute positively to teachers’ perceived well-being as well as characteristics that diminish teachers’ perceived well-being. Implications for practice are discussed.
Neoliberal discourses in Spanish for business: An ethnographic classroom study
Authors: Rubio Jesse W.
Published: January 2021

Beginning in the 1970s, education has responded to the rise of neoliberalism across macro-, meso-, and micro-level contexts through shifts in practice and structure. Meanwhile, language learning is often promoted as an instrument in job attainment and transnational business communication. For example, in language education, courses in language for specific purposes, whose ubiquity continues to increase, often reflect the market rationality embedded in contemporary education and support an instrumental orientation to language learning. This ethnographic study investigates the neoliberal discourses taken up by students and the instructor in a university-level Spanish for Business classroom. Drawing on triangulated data from classroom observations, field notes, informal interviews with students and the instructor, and a semi-formal interview with a focal student participant, the findings suggest that competition, compliance, and individualism were among the ideological discourses of the classroom. However, while societal and institutional discourses of neoliberalism were often interpellated, they were also resisted. Implications for praxis are also discussed.
Imagining a good citizen: The roles of a historical hero in Slovak pedagogical tradition
Authors: Otčenášová Slávka
Published: January 2021

Based on a diachronic case study of history textbooks used in Slovak primary and secondary schools since 1918, this article discusses the roles biographies of historical heroes can play in school education. The case study analyses history textbook narratives about the medieval ruler Svätopluk published during three different political regimes, tracing their heritage up to present-day history textbooks. The text argues that the presentation of Svätopluk’s qualities, talents and achievements has been used not only in depicting him as a representative of the community, and as a desired prototype of a good citizen, but also in the formation of negative stereotypes about the representatives of the Other. This excluded significant segments of pupils of certain national minorities from the mainstream narrative and labeled them as enemies. An examination of the images of Svätopluk in history textbooks confirmed that these were politically motivated and influenced by current ideologies. However, it also showed that 19th century Romanticist ideals, resulting in apologetic and nation defending narratives, remained an integral part of history textbooks throughout the 20th century, prevailing over the narratives offered by official contemporary historiography.
Alternative prey influence the predation of mosquito larvae by three water bug species (Heteroptera: Nepidae)
Authors: Saha Nabaneeta , Kundu Malini , Saha Goutam K. , Aditya Gautam
Published: January 2021

The indirect interactions among multiple prey sharing a common predator characterize apparent competition. In conservation biological control involving mosquitoes and controphic prey against generalist insect predators, apparent competition may be a crucial factor determining the extent of success. The possible influence of apparent competition on mosquito prey consumption by three water bugs (Heteroptera: Nepidae): Ranatra elongata, Ranatra filiformis, and Laccotrephes griseus was assessed under laboratory conditions. Tadpoles (Duttaphrynus melanostictus), chironomid larvae, snails (Racesina luteola) and fish fingerlings (Labeo rohita) were considered as alternative prey under two prey or multi prey conditions against instar IV larvae of Culex quinquefasciatus as target prey. Under two prey conditions all the predators exhibited a preference (significant Manly’s α) for mosquito larvae, against fish fingerlings by R. filiformis. In the presence of multiple prey, mosquito larvae were selected by the predators. Using the ratio of mosquito selectivity in two prey and multi-prey conditions as a measure of apparent competition, chironomid larvae had greatest effect in suppressing mosquito selectivity for R. elongata, and fish fingerlings for R. filiformis and L. griseus. It seems that the prey preference of R. elongata, R. filiformis and L. griseus may differentially evoke apparent competition among the prey. In the aquatic community where these predators and prey coexist, mosquito larvae may benefit from apparent competition that reduces their vulnerability to predators. The identity of the alternative prey appears to be an important factor for shielding the vulnerability of mosquito prey to the generalist insect predators.
Importance of environmental flows in the Wimmera catchment, Southeast Australia
Authors: Atazadeh Ehsan , Barton Andrew , Razeghi Jafar
Published: January 2021

In this paper the environment, climate, vegetation, indigenous and European settlement history, stream flow patterns, water quality and water resources development in western Victoria, Australia are studied. The last part of the paper focuses on the MacKenzie River, a tributary of the Wimmera River located on the northern slopes of the Grampians Ranges in western Victoria, Australia. Water release along the MacKenzie River was regulated to improve water quality, stream condition and river health especially in the downstream reaches. The upstream section tends to receive water most days of the year due to releases to secure the requirements of water supply for the city of Horsham and its recreational and conservation values, which is diverted into Mt Zero Channel. Below this the middle and downstream sections receive a more intermittent supply. Annually, a total of 10,000 dam3of water is released from Wartook Reservoir into the MacKenzie River. Of this volume, only about 4,000 dam3 was released explicitly for environmental purposes. The remaining 6,000 dam3was released to meet consumptive demands and to transfer water to downstream reservoirs. The empirical data and models showed the lower reaches of the river to be in poor condition under low flows, but this condition improved under flows of 35 dam3per day, as indicated. The results are presented to tailor discharge and duration of the river flows by amalgamation of consumptive and environmental flows to improve the condition of the stream, thereby supplementing the flows dedicated to environmental outcomes. Ultimately the findings can be used by management to configure consumptive flows that would enhance the ecological condition of the MacKenzie River.

Published: January 2021

This qualitative study was conducted to provide a model of managerial practical wisdom in public hospitals in order to define the components affecting managerial practical wisdom, development strategies and its results in hospitals based on interpretive paradigm using Grounded strategy and content analysis technique and based on paradigm model of Corbin and Strauss (2008). To this end, semi-structured interviews were conducted with 21 hospital managers, professors and experts in the field of health care management. The basic themes of the interviews during the data analysis and coding stage identify the central class, causal, contextual, intervening factors, strategies and consequences of managerial practical wisdom in the form of a paradigm model and finally to create Grounded theory about managerial practical wisdom in these hospitals. Accordingly, the dimensions and components of practical wisdom among the managers of the mentioned hospitals were cognitive abilities and managerial competencies, factors affecting its development including individual factors (personal experiences, personality pattern, and individual values) and organizational factors (spirituality at work, organizational values and organizational will).Moreover, the results of developing this type of wisdom among the mentioned managers can be categorized as individual results (mental and psychological well-being), organizational results (improving service quality, stakeholder satisfaction, organizational dynamism and agility, organizational vitality and organizational citizenship behaviors) and social outcomes (social capital development). These results can be used in the creation and development of quantitative tools for measuring managerial practical wisdom and as a qualitative complement in evaluating the quality of decisions among hospital managers.

Job stress and organizational citizenship behavior among university teachers within Bangladesh: mediating influence of occupational commitment
Authors: Amin Ruhul , Hossain Md. , Masud Abdullah
Published: January 2021

This study aims to explore the impact of job stress on organizational citizenship behavior (OCB) among university teachers in Bangladesh along with the mediating effect of occupational commitment (OC) on this relationship. An online questionnaire survey using the Google form was conducted to collect data from respondents. 244 valid samples were analyzed using bivariate correlation and regression analyses. The results of hierarchical regression analyses reveal that job stress is negatively and significantly linked to OC when controlling for demographic variables, such as age, gender, educational qualification, type of university, designation, and teaching experience; surprisingly, it has no significant effect on OCB. However, OC is positively related to OCB. Also, the OC has a full mediating influence on the linkage between job stress and OCB. With the support of mediation test, this study suggests OC as a personal resource and mechanism to better manage teacher job stress and improve OCB. Detailed implications and contributions have been discussed in the previous sections.

Authors: Mamcarczyk Mariola , Zieniuk Paweł
Published: January 2021

At present 177 thousand associations and 26 thousand foundations operate in Poland, which are involved in many different areas of public benefit activities and finance their activities from various sources. The paper presents the results of own studies carried out on a sample of 100 public benefit organisations conducting activity in the area of supporting and promoting physical education and sport. The main objective of the paper concerns presentation of the possibilities of acquiring funds by the organisations to carry out the statutory tasks associated with the development of sport and physical education and the structure of sources of financing this activity in practice of Polish foundations and associations. The paper analyses legal regulations and domestic and subject literature, presenting possible financing sources of activity of Polish organisations. The empirical studies were carried out based on analysis of the content of substantive reports of public benefit organisations. The verification of statistical hypotheses was carried out using the structure indicator test. The results of the conducted studies confirm the main hypothesis, according to which the public benefit organisations finance the activity promoting sport and physical education mainly from public sources, with the funds originating from the local government budgets playing the most important role. The paper also presents the results regarding the structure of the funds originating from private sources and the mechanism of 1% of personal income tax. The paper tackles the subject seldom discussed in the literature and can play a role in the discussion on the system of financing the public benefit activities given the dynamic development of non-government organisations sector.

Authors: Terekhina N.A. , Goryacheva O.G.
Published: January 2021

Oxidative stress is one of the most important mechanisms of cardiovascular diseases, especially in heart failure. Mitochondrial dysfunction and inflammation play a major role in formation of free radicals and antioxidants. The association between oxidative stress, telomere biology and cell senescence plays the key role in cardiovascular pathology development. The paper considers role of pro-oxidant and antioxidant enzymes in heart pathology development. Specifically, the role of such antioxidant enzymes as glutathione peroxidase 3, catalase, and superoxide dismutase is described. The role of gamma-glutamyl transferase is emphasized as its activity increases significantly in cases of heart failure, coronary heart disease, stroke, arterial hypertensions, and arrhythmias. This article is a literature review of the effect of such antioxidants as alpha-tocopherol, ubiquinone, uric acid, and triiodothyronine on development of heart failure and myocardial infarction. A decrease in triiodothyronine concentration is a risk factor for coronary heart disease. High uric acid values in patients with myocardial infarction upon admission to the hospital are associated with a high risk of sudden death. The influence of such minerals such as zinc, copper, magnesium, selenium, potassium, sodium, calcium, and iron on heart failure development has been analyzed. The role of ceruloplasmin as an independent predictor of acute and chronic cardiac disorders cardiac events, mortality, and bad prognosis in patients with heart failure and myocardial infarction is examined. The authors demonstrate the influence of inflammation on heart failure development as well as association of inflammation with oxidative stress.

Methicillin-resistant Staphylococcus aureus (MRSA) is a major multidrug-resistant nosocomial pathogen. This class of MRSA, first reported in the early 1960s and now termed healthcare-associated MRSA (HA-MRSA), was followed by a newer class of MRSA, community-associated MRSA (CA-MRSA). The unique feature of the initial CAMRSA included Panton-Valentine leukocidin (PVL), an abscess-associated toxin and also S. aureus spread factor. CA-MRSA usually causes skin and soft-tissue infections, but occasionally causes invasive infections, including (necrotizing) pneumonia, sometimes preceded by respiratory virus infections. The most successful CA-MRSA USA300 (ST8/SCCmecIVa) caused an epidemic in the United States. In Russia, we first detected PVL-positive CAMRSA (ST30/SCCmecIVc) in Vladivostok in 2006, but with no more PVL-positive MRSA isolation. However, we recently isolated four lineages of PVL-positive MRSA in Krasnoyarsk. Regarding chemotherapy against invasive MRSA infections, vancomycin still remains a gold standard, in addition to some other anti-MRSA agents such as teicoplanin, linezolid, and daptomycin. For resistance, vancomycin-resistant MRSA (VRSA) with MICs of ≥16 μg/mL appeared in patients, but cases are still limited. However, clinically, infections from strains with MICs of ≥1.5 μg/mL, even albeit with susceptible MICs (≤2 μg/mL), respond poorly to vancomycin. Some of those bacteria have been bacteriologically characterized as vancomycin-intermediate S. aureus (VISA) and heterogeneous VISA (hVISA), generally with HA-MRSA genetic backgrounds. The features of the above PVL-positive Krasnoyarsk MRSA include reduced susceptibility to vancomycin, which meets the criteria of hVISA. In this review, we discuss a possible new trend of PVL-positive hVISA, which may spread and threaten human health in community settings.
A tale of two cities: The comparative chrono-urbanism of Brno and Bratislava public transport systems

Time policies in urban environments are discussed in this article, including some difficulties in comparing such policies between cities and in an international comparison of urban times in general. In response to the need to systematise methodological approaches to the comparison of urban time policies, we offer a concrete solution in terms of a comparative chrono-urbanism. The main issues under consideration are the theoretical framings, systematic procedures and an empirical illustration comparing two urban times. The comparison serves as a tool for assessment, when one urban time becomes a criterion for another urban time. This approach is applied in the case of an international comparison of two similar cities – Brno (Czech Republic) and Bratislava (Slovak Republic). Their urban times are operationalised through the timetables of their public transport systems, the lines of which are conceived as the institutional carriers of urban time. Based on the analysis of timetables from 2016, we present a detailed description of urban times of Brno and Bratislava, as well as their comparison, which makes it possible to assess the time policies in both cities, as well as their implications for planning.

People with severe mental illness face a different ‘interventional’ landscape compared to some decades ago, when mental hospitals were dominant, in Sweden as well as in the rest of the Western world. The aim of the research reported in this article was to follow men and women diagnosed with psychosis for the first time over a 10-year period, and to explore what interventions they experienced. The interventions, here defined as “spheres”, were either community-based or institutional. A third sphere represents no interventions. Based on data from registers and using a time-geographic approach, the individuals were visualised as 10- year trajectories where their transitions between the different spheres were highlighted. The results show a great diversity of trajectories. Two main categories were detected: two-spheres (community-based and no interventions) and three-spheres (adding institutional interventions). One third of the population experienced only community-based interventions, with a higher proportion of men than women. Consequently, more women had institutional experience. Two sub-categories reveal trajectories not being in the interventional sphere in a stepwise manner before the 10th year, and long-term trajectories with interventions in the 10th year. The most common pattern was long-term trajectories, embracing about half of the population, while one-fifth left the institutional sphere before the 5th year.
