Background/Aim. Analyses of the cephalometric value of profile radiographs are very important for orthodontic diagnosis and planning of therapy. These values differ morphologically depending on ethnic and racial affiliation. The aim of this study was to confirm variations of cephalometric norms and the extent of their value and, according to them, confirm the harmony concept of craniofacial morphology among the young Serbian population in Kosovo and Metohija. Methods. This retrospective study comprised 183 profile radiograms of patients from Kosovo and Metohija, Serbia, aged 8?33, from which Class I was ascertained among 82 patients (53 female and 29 male). Five cephalometric angles were measured and analyzed. Pearson?s correlation coefficient was used to define the strength of correlation between the five variables. Bivariable linear regression was used to form harmonious combinations of individual values in the insight of craniofacial harmonious form. Multiple regression and standard error were used to form a harmonious schema. Results. Linear regression equations were used to define cephalometric floating norms. They helped us form a harmonious box and harmonious schema of craniofacial norms of the participants. The ex-tent of harmonious value for orthognathic profile of our examinees varies for sella nasion subspinale (SNA) angle from 78? to 81?, for sella nasion supramentale (SNB) angle from 75.1? to 78.1?, for maxillary line ? nasion sella line (NL-NSL) angle from 11.5? to 5.5?, for nasion sella basion (NSBa) angle from 134.7? to 125.8?, and for mandibulary line ? nasion sella line (ML-NSL) angle from 40.5? to 30.6?. Conclusion. Cephalometric floating norms that describe the individual craniofacial pattern among the young Serbian population in Kosovo and Metohija, determined and defined by five cephalometric variables, and presented in the form of a harmonious box and harmonious schema and can accurately determine the craniofacial pattern.
"In this Industry, You're No Longer Human": An Exploratory Study of Women's Experiences in Pornography Production in Sweden
Authors:   Talita, Sweden, Donevan Meghan
Published: May 2021

Despite being a global, billion-dollar industry, very little is known about the conditions women face within the pornography industry. The aim of this study was to explore women’s experiences in pornography production, with a particular focus on structural antecedents to entrance, coercion, and violence within the industry, as well as current needs and any barriers to exiting the industry. Semi-structured, in-depth interviews were conducted with nine women with experiences in pornography production in Sweden. Participants identified young age, financial insecurity, earlier exposure to sexualized violence, and poor mental health as typical antecedents to entering the pornography industry. Once in the industry, women risk manipulation and coercion by pornographers and porn buyers, making it difficult to maintain personal boundaries. Women are regularly harassed by porn buyers who send requests to purchase specific sexualized acts online or offline. The greater a woman’s vulnerability, the more difficult it is to resist pornographer’s and porn buyer’s demands. Experiences in prostitution and other forms of commercial sexualized exploitation are common. A significant barrier to exiting pornography production is the distress of having one’s pornographic images remain online indefinitely. In order to exit the pornography industry and access real alternatives, participants stressed the importance of vocational training, further education and psychosocial support. This study is an important step in elucidating the situation faced by women in pornography production. Further documentation of harms and assessment of needs is warranted for policymaking and the development of effective support services for this vulnerable population.

Cardanol-based novolac-type phenolic resin was synthesized with a mole ratio 1.0:0.5 of cardanol-to-formaldehyde using a dicarboxylic acid catalyst such as succinic acid. The cardanol-based novolac-type phenolic resin may further be modified by epoxidation with epichlorohydrin excess at 393 K in a basic medium to duplicate the performance of such phenolic-type novolacs. Carboxyl-terminated butadiene acrylonitrile copolymer (CTBN) has been studied by various researches with diglycidyl ether of bisphenol-A (DEGBA) epoxy resin and epoxidized phenolic novolac resins. The epoxidized novolac resin was blended with different weight ratios of carboxyl-terminated butadiene acrylonitrile copolymer (CTBN) and cured with a stoichiometric amount of polyamine curing agent. The formation of various products during the synthesis of cardanol-based novolac resin, epoxodized novolac resin and blending of epoxidized novolac resin with CTBN has been studied by Fourier-transform infrared (FTIR) spectroscopic analysis. Further, the products were confirmed by a proton nuclear magnetic resonance (1H-NMR) spectroscopic analysis. The number average molecular weight was determined by a gel permeation chromatography (GPC) analysis. The blend sample, having 15 wt % CTBN concentration showed minimum cure time and most thermally stable systems.

Published: May 2021

In this paper, we study zealots' effects on social networks. Our social network is based on scale-free networks using Barabasi–Albert method and random networks using Erdős–Rényi method. We used a pre-studied modified Voter model that includes zealots, individuals who never change their opinions. We chose prominent individuals (i.e. hubs) as zealots. In this way we first chose important individuals with high degree (hubs); second, individuals with high closeness. And then examined the consensus time compared with that zealots are chosen as non-important individuals. We found that the time to get to the consensus state in social networks is the same for different numbers of zealots but with the same degrees of contamination with zealotry. For example, one zealot's effect with a degree of 64 is same to 8 zealots' effects with a degree of 8.

Trata-se de uma pesquisa-ação colaborativo-crítica desenvolvida em uma escola municipal de ensino fundamental de Vitória (Espírito Santo). A investigação é um desdobramento do projeto “Observatório Nacional de Educação Especial: estudo em rede nacional sobre as salas de recursos multifuncionais nas escolas comuns”, cujo objetivo foi promover formações continuadas com professores com ênfase na inclusão de estudantes público-alvo da educação especial nas escolas por meio de práticas pedagógicas inclusivas. Fundamenta-se nas concepções de Meirieu (2002, 2005), que defende a educação para todos e os investimentos na formação docente. Aplica, como procedimentos teórico-metodológicos, a observação do trabalho pedagógico no cotidiano escolar, os momentos de formação, a colaboração nas atividades de classe e as entrevistas semiestruturadas. Os dados, produzidos entre março e outubro de 2015, conduzem ao entendimento de que os momentos de formação continuada são espaços-tempos propícios para problematizar as práticas pedagógicas e o uso de laudos médicos como elementos que podem induzir à rotulação dos discentes como sujeitos não propensos à aprendizagem, culminando na negação do direito à educação. As formações desafiaram os professores à pesquisa, ao estudo, à desconstrução de verdades cristalizadas sobre os alunos e à busca por novas alternativas de ensinar a todos.
Value-added measures in higher education: a historical contextualization of Brazilian experiences
Authors: Duarte Couto Fernandes Vivian , José Miranda Gilberto , Alexander Nicola
Published: May 2021

School quality assessment has been the object of research of economists, educators, policymakers, and various stakeholders worldwide. In Brazil, the National Assessment System for Higher Education is an initiative that seeks to assess the country’s undergraduate programs, their faculty, and student achievement, as well as to provide quality indicators that account for the differences between them. One such indicator is the Indicator of Difference Between Observed and Expected Achievements (IDD), which measures the contribution of undergraduate programs to student achievement. Since 2006, policymakers have altered their estimation methodology, seeking to improve it as an accurate value-added measure. This research aims to discuss this change and its impacts on the ranking of undergraduate programs in Accounting in Brazil. A quantitative design was used to test four value-added models included in the historical records of the IDD and to identify the impact of these methodologies. The sample consisted of 30,668 students from 911 accounting schools. The results show that the current model is more accurate than the previous ones. However, both the literature and the findings indicate that the model could be improved by introducing explanatory variables for academic achievement that cannot be controlled by higher education institutions. The IDD is still unsuitable because it considers all institutions and all students equal.

Authors: Durmus Ensar , Guneysu Fatih
Published: May 2021

Aim: It is aimed to examine the status and demographic characteristics of COVID-19 Reverse Transcription Polymerase Chain Reaction (RTPCR) positive staff working in the hospital during the pandemic period. Material and methods: This is retrospective, descriptive research. All hospital personnel working at Sakarya Training and Research Hospital and tested positive for COVID-19 RT-PCR between 01/11/2020-30/11/2020 were included in the study. Results: During the study period, the number of hospital staff who tested positive for COVID-19 RTPCR was 340 people. Of the personnel, 228 (67.1%) were female, the mean age of all healthcare workers was 32.7 (± 8.3) years. The number of non-physician healthcare workers was 162 (47.6%), workers were 143 (42.1%), and physicians were 35 (10.3%). Among all hospital personnel, the COVID-19 RT-PCR test was positive in emergency room workers, with a maximum of 61 people (17.9%). It was followed by 43 (12.6%) people working in non-COVID clean wards. Conclusions: It would be beneficial for all staff working in the hospital during the pandemic to pay attention to apply personal protective equipment during their work, notwithstanding whether the COVID-19 patient is caring or not. Simultaneously, healthcare professionals should be careful about COVID-19 transmission in their social life outside of the hospital.

Published: May 2021

Introduction:
Thyroid carcinoma is the most common endocrine cancer. Some somatic mutations in genes (BRAF, NRAS and TERT) involved in key signaling pathways and genome stability have been recently identified to play an important role in its development. Very little research has been done on their frequency and clinical relevance in Bulgarian patients with papillary thyroid cancer (PTC). This study is focused on investigating somatic mutation frequency in Bulgarian patients with PTC and their association with clinicopathologic features.

Material and Methods:
The study included 50 PTC from Bulgarian patients analyzed for mutations in BRAF (V600E), NRAS (Q61K), single nucleotide polymorphism (SNP) rs2853669 and TERT (C228T and C250T) genes by Sanger sequencing. The results were interpreted using Benchling and SeqScape software, and statistical analysis performed with SPSS.

Results:
In the studied PTC group BRAF(V600E) and TERT (C228T) mutations were found with frequency of 24% and 2%, respectively. Co-occurrence of both mutations was found in 1 patient (2%). The mutations Q61K (NRAS), and C250T (TERT) were not detected. The SNP rs2853669 was found in 18 patients (52.9%). Correlation analysis with the clinical characteristics of the patients revealed statistically significant association with larger size of the tumor for BRAF(V600E) and smaller tumor size for rs2853669.

Conclusion:
In the present pilot study, we found that BRAF(V600E) and rs2853669 in TERT are common among PCT patients. While the presence of BRAF V600E mutation was associated with large tumors, the presence of rs2853669 in TERT was found in the majority of PCT below 2 cm. More extensive molecular genetic analysis of TERT, BRAF or RAS mutations in larger sample is needed to further elucidate the clinically important diagnostic and prognostic biomarkers for thyroid cancer.
Clinical Study of the Change of pH Level in the Supragingival Plaque in Children after Taking Homeopathic Remedies
Authors: Pomakova A. , Gateva N. , Hristov K.
Published: May 2021

Objective: There are numerous publications on the parameters of conventional medications, which contribute to their cariogenic and erosive potential. Little is known about the homeopathic remedies (HR) and the changes in the oral cavity they lead to, especially during childhood.

Material and methods: The study involved 25 children (5-9 years of age). It monitored the change in plaque pH level after intake of three frequently used homeopathic remedies in five consecutive weeks. The pH level values were measured after the administration of the remedies, without HR intake, and after rinsing with 10% sucrose solution. Five groups were formed – two controls and three groups with results from the tested HR.

Results: A drop in the plaque pH level was observed after intake of all HR and in all tested individuals. The biggest decrease was observed at the 15th minute for all HR. At the 30th minute the greatest decrease was observed with the second remedy, and at 60th minute – with the first and second.

Conclusions: A dramatic decrease in the plaque pH level was observed after intake of each studied remedy. In many cases the drop was below the critical value of pH = 5.5. The low plaque pH values were maintained even at the 60th minute after the start of the study.

Published: May 2021

This article sheds light on some features of ghrelin (GHR)- and tryptase (Try)-positive mast cells (MCs) distribution in human lung of preterm newborns with respiratory distress syndrome (RDS). GHR possessed anti-inflammatory activity and reliable therapeutic properties in some lung diseases. So far, GHR expression has been defined predominantly in neuroendocrine cells of bronchial mucosa in fetal and infant lungs. Lung tissue from 8 dead newborns with RDS were investigated immunohistochemically with anti-GHR and anti-Try antibodies. The number of GHR+ and Try+ MCs was determined in three locations –bronchi, bronchiole and in alveolar septa. MCs were more numerous around main bronchi with diminishing numbers around bronchiole and in alveolar septa. The number of MCs in the latter was increased in newborns with pneumonia. The number of GHR+ MCs in alveolar septa was lower in newborns with RDS as compared to newborns with RDS combined with pneumonia (2.83 ± 1.13 vs 4.81 ± 2.6, p < 0.001). The amount of Try+ MCs along bronchial wall was significantly more than GHR+ MCs in RDS newborns (6.97 ± 4.53 vs 3.85 ± 4.30, p = 0.001). It could be supposed that pulmonary MCs increased in newborn lungs in inflammatory process. MCs in human lung contained GHR peptide that had immunomodulatory function and participated in hormone regulation of inflammation.
Epidemiological Analysis of Leptospirosis in Bulgaria, 1999-2018
Authors: Angelova S. , Mitova Y. , Doycheva V.
Published: May 2021

Background: The aim of the study was to characterize the epidemic process of leptospirosis in Bulgaria.

Material and methods: Data was collected from the National Centre for Public Health and Analysis official database of infectious diseases for the period 1999-2018 year. Graphical methods, absolute and relative values were applied when analyzing the data. A regression analysis was used to search for trends in incidence rate and mortality rate over a period of time.

Results: For the period 1999-2018, a total of 414 cases of leptospirosis were registered in Bulgaria, 35 of them were lethal. Incidence ranged from 0,10 per 100 000 population (2012, 2017 year) to 0,63 per 100 000 (1999 year). Using the regression analysis method a model p = 0,03 < 0,05 was constructed, which most adequately described the tendency of leptospirosis incidence rate in Bulgaria. Mortality rate was the highest in 2000 – 0,09 per 100 000 and was zero for six years of the survey period. An adequate model was developed p = 0,005 < 0,05, which showed the trend of leptospirosis mortality rate. The case-fatality rate was high and reached 27,27% in 2010. The highest incidence rate of leptospirosis was in the areas of Yambol and Shumen. Leptospirosis in Bulgaria had a seasonal trend. Risk factors for the disease were male gender and age over 55 years.

Conclusions: Global environmental changes, including extreme weather conditions, increase the threat of severe epidemics of leptospirosis worldwide. An unfavorable impact on the spread of leptospirosis is the intensive migration of the population and travel-associated cases. Modern control over leptospirosis should be constant, complex and ubiquitous. Therefore, leptospirosis in Bulgaria should not be underestimated.

Published: May 2021

Aim: To compare the level of diagnostic coincidence between classical (standard) method and VELscope and ViziLite Plus systems in the diagnosis of different oral lesions.

Material and methods: 184 oral lesions were examined using classical method, VELscope and ViziLite Plus systems, and after that underwent a pathohistological examination for diagnosis proof. The percentage of diagnostic coincidence for various types of lesions was analyzed for the three methods compared.

Results: The results demonstrated the highest coincidence rate for lesions diagnosed with VELscope – 35 (83.3%), followed by those with classical method – 80 (80.8%), and those with the application of ViziLite – 33 (76.7%). In premalignant and malignant lesions, the highest percentage of diagnostic coincidence was reported using the classical method – 14 (93.3%), for non-malignant lesions using VELscope – 28 (84.8%), for inflammatory and reactive lesions using VELscope – 14 (82.4%) and for lesions associated with general disease and systemic medication again using VELscope – 11 (91.7%).

Conclusion: Non-invasive methods, tested in the study, have different diagnostic properties when differentiating particular clinical types of lesions. They are highly sensitive to changes in the oral mucosa but the final diagnosis must always be proved with biopsy.
Algorithm-Based Advertising: Unintended Effects and the Tricky Business of Mitigating Adverse Outcomes
Authors: Lambrecht Anja , Tucker Catherine
Published: May 2021

Some algorithms may have similar discriminatory tendencies to humans. The presented study investigates gender bias in social media advertising in the context of STEM careers. Results suggest that advertising algorithms are not gender-biased as such, but that economic forces in the background might lead to unintended, uneven outcomes. Spillover effects across industries make reaching some consumer segments more likely than others. A gender-neutral strategy is less likely to reach women because women are more likely to react to advertising. Therefore, targeting them is more expensive and economic forces unintentionally favor men. One potential solution could be running separate campaigns for men and women to target both demographic groups equally. However, anti-discrimination legislation in many countries does not allow companies to target employment ads to only one gender. So ironically, laws that are designed to avoid discrimination actually rule out a fairly simple way to correct the bias in online targeting on Facebook and other platforms, illustrating further need for policy guidance in this area.
Metrics Gone Wrong: What Managers Can Learn from the 2016 US Presidential Election
Authors: Kübler Raoul , Pauwels Koen
Published: May 2021

In the 2016 presidential election, the vast majority of available polls showed a comfortable lead for Hillary Clinton throughout the whole race, but in the end, she lost. Campaign managers could have known better, if they had had a closer look at other data sources and variables that – like polls – show voter engagement and preferences. In the political arena, donations, media coverage, social media followership, engagement and sentiment may similarly indicate how well a candidate is doing, and most of these variables are available for free.

Validating the bigger picture with alternative data sources is not limited to politics. The latest marketing research shows that online-consumer-behavior metrics can enrich, and sometimes replace, traditional funnel metrics. Trusting a single ‘silver bullet’ metric does not just lead to surprises, it can also mislead managerial decision-making. Econometric models can help disentangle a complex web of dynamic interactions and show immediate and lagged effects of marketing or political events.
Instead of People Using Technology, Technology Is Using People
Authors: Rushkoff Douglas
Published: May 2021

The progress of artificial intelligence and new technologies triggers hot debates about the future of human life. While fans of the singularity say that artificial intelligence will become smarter than human beings and should take over the world, for others, such a vision is a sheer nightmare. Douglas Rushkoff is clearly part of the second group and takes a passionate pro-human stance. He explains why giving too much way to technologies is a mistake and why humans deserve a place in the digital future. Already today, technologies have a much stronger impact on our lives than most of us would believe. For him, being human is a team sport, and he asks for a more conscious use of technologies while keeping rapport with other people. To safeguard the humanness in a tech world, he advises to carefully select the values we embed in our algorithms. Rather than serving perpetual growth, technologies ought to help people reconnect with each other and their physical surroundings.
Young but not Naive: Leaders of Tomorrow Expect Limits to Digital Freedom to Preserve Freedom

Published: May 2021

In a recent survey, about 900 “Leaders of Tomorrow” from more than 90 countries all over the world shared their opinions about “the impact of new technologies on human freedom of choice.” They take a very clear stance against unlimited freedom of speech on the Internet. The majority thinks platforms that until now have often taken a “hands off” approach, rejecting content filtering by claiming they are “just the messenger,” should be obliged to prevent and censor hate speech and fake news on the Internet. Platforms are expected to work hand-in-hand with state institutions to better prevent online manipulation and abuse and to protect personal data. The Leaders of Tomorrow also advocate that personal data should be controlled by their owners when they are used by online platforms. Applications that lack transparency and cannot be influenced by the customer are met with the highest extent of objection.

Case and Challenges for Universally Subsidized Child Care in Canada
Authors: Daoyun Yang Cecilia
Published: May 2021

This presentation presents a case for universally subsidized childcare. It examines the need for change, gives an overview of the current options available to Canadian families, followed by an examination of alternative policies, costs and benefits of subsidized childcare, different modes of implementation, and costs and benefits of each mode of implementation. While there are many policies that can improve the lives of Canadian mothers’ and children for the better, few can deliver the widespread social and economic benefits that can be achieved through universally subsidized childcare. This presentation identifies many of the harms and difficulties regarding the implementation of such a program but still recommends it because the benefits are so immense.
Housing Issues On and Off First Nations Reserves in Canada
Authors: Rowe Ellen
Published: May 2021

This paper discusses the problems of the lack of certification of possession (property) and poor housing conditions within First Nation communities both on and off reserves in Canada. It argues that in the last 140 years, Indigenous peoples have become dependent on the resources provided by the Canadian government, as first agreed upon in the Indian Act of 1876. Investigating the causes, potentially including budgeting constraints or Department of Indigenous Affairs regulations will provide a clearer understanding to what are the factors causing the problems. There have been significant decreases in the amount of money given to reserve communities, which can be seen to have elevated homelessness and over-crowding in existing dwellings. As explained in the Senate Report of 2007, due to lack of housing, "16 or more members of the reserve can be found living under the same roof."[1] In this research essay, the Indian Act will be examined in order to determine what barriers exist, that continue to prevent communities on and off reserves from gaining the certification of possession in Canada and improving housing conditions. First Nations populations continue to rely on aspects of the Indian Act and any funds provided by the Federal Government, which continues to result in shortages of basic essentials such as housing. Even so, governmental policies and documents such as Senate reports or First Nations organizations remain useful in presenting new ideas for solving ramifications, across the country.

This study evaluates the spatial accessibility of playgrounds within the city of Kingston in relation to neighbourhood socioeconomic status and major city intersections. Using a geographical information system, all playgrounds within Kingston and the surrounding area were plotted. Constructing buffers to measure walking distance, major intersection distance and neighbourhood accessibility, nearest playground distance was found. Through introspective inquiry using the Seven C’s guide to young children’s outdoor play spaces, playgrounds were surveyed and scored based on relevant criteria. Scores were included to calculate buffer size as well as neighbourhood socioeconomic status. Quintiles (Q1-Q5) were also plotted on the map to ensure accurate representation of neighbourhoods based on the Canadian Marginalization Index. It was concluded that residential segregation disproportionately places lower scoring playgrounds in more impoverished neighbourhoods (Q4 & Q5) while high scoring playgrounds were almost always within middle to high income neighbourhoods (Q1-Q3). Using this information, further analysis is being conducted on children’s Right to the City as well as playground accessibility and unstructured play developmental benefits.
An Analysis of the F1 Phase in the Pigeon's Pecking Movement
Authors: Smail Lauren
Published: May 2021

During pecking, pigeons perform two distinct stop phases with their head, F1 and F2, which are hypothesized to represent respectively the pigeon’s decision to peck at a broad target area, and the calculation of finer details such as depth and size of a target. Our study was conducted to assess the function of these phases, with a focus on the decision making stop phase (F1).  Pigeons were trained with operant conditioning to distinguish between two circular white stimuli: one surrounded by a red square and the other by a yellow square. Once the pigeon reliably chose the correct coloured stimulus, we made them increasingly similar in colour. If the F1 phase represents the decision to peck, then as the stimuli become difficult to distinguish, F1 durations should increase.  The results show that pecking accuracy decreased as the two stimuli became more similar, allowing us to see that the decision had become more difficult for the bird. However, decision difficulty was unrelated to stop phase duration.  The current results do not confirm our hypothesis that the F1 phase is where the decision to peck occurs. However, these results are based on preliminary data from a small sample size, and as such we are limited in what we are able to conclude.  The decreased pecking accuracy as decision difficulty increased is promising, and while this pattern of increased difficulty was not exhibited in our F1 stop phase duration analyses, the trend may become pronounced as we continue to collect more data.

У статті розкрито загальні положення проблеми суїцидальної поведінки, виявлено основні причини виникнення та чинники перебігу суїцидальної поведінки підлітків, а також основні ознаки суїцидальних тенденцій неповнолітніх. На сьогоднішній день недостатньо визначеним є питання про те, зусиллями яких фахівців – педагогів, лікарів, психологів, соціальних педагогів, повинна проводитися робота з підлітками з профілактики та корекції суїцидальної поведінки, адже зусилля педагогів недостатні через їх низьку обізнаність у питаннях суїциду, а можливості медиків обмежені недостатністю навиків роботи з цією категорією дітей. Oхарактеризовано особливості соціально-педагогічної профілактики означеного негативного явища, в тому числі і суїцидальної поведінки в учнівському середовищі. Bизначено основні компоненти соціально-педагогічної профілактики, проаналізовано основні методи, форми, напрями соціально-педагогічної профілактики та корекції у діяльності соціального педагога та практичного психолога щодо запобігання проблеми самогубства у підлітковому віці.

Malaysian secondary schools are facing a shortage of male teachers. Almost 70% of the teaching profession is dominated by female teachers. There is an obvious gap in the reason why teaching is not preferred by the male gender. This study intends to find the determinants of career success among male teachers with the hope of revealing the career success factors that are associated with male teachers.  A survey was done among 140 male teachers in a secondary school in the state of Malacca, Malaysia. Results showed that 3 out of 5 of the determinants factors are significantly explaining career success among the teachers (Emotional Intelligence, Person-Job-Fit & Work-Life Balance) while two others are unable to explain the career success of the teachers (Career Adaptability & Career Commitment). The findings enable policymakers to prioritize and draft better career development plans for the teachers that focus on issues about the recruitment of more emotional intelligence teachers, optimize person-job-fit and designing jobs that emphasize work-life balance.
