In December 2021 a famous Greek TV and radio journalist and well-known anti-vaxxer, Yiorgos Tragkas, passed away due to Covid-19 complications. In the previous two decades, Tragkas had become a controversial figure, employing an anti-elite, pro-Russian and anti-Western narrative that fed into the country's underdog culture. His ethnocentric, populist, toxic tabloid journalism had been a popular genre in Greek political culture since the early 1980s. However, the debt and migration crises that shook Greece fuelled populist politics and a wave of misinformation.1 Tragkas jumped on the bandwagon of this new era by whitewashing the neo-Nazi Golden Dawn Party on national TV and by live appearances dressed up as a Second World War Nazi officer, with photos of Adolf Hitler and Angela Merkel on his desk.

There are no data about the prevalence of domestic violence during pregnancy in Greece. The purpose of this study is to determine the prevalence and the associated factors of domestic violence in a representative population of pregnant women in Greece. Five hundred and forty-six consecutive women, in outpatient clinics of two Public General Regional Hospitals in Athens, agreed to answer anonymously the Abuse Assessment Screen (AAS) questionnaire, translated into the Greek language. Five hundred and forty-six questionnaires were returned (100% response rate), revealing that the prevalence of domestic violence in pregnancy is 6%, with 3.4% of the sample having being abused since the beginning of pregnancy, mainly by their husband/partner. The factors associated with higher risk of abuse during pregnancy were nationality, socio-economic background, and educational level. Foreign women or women with a foreign partner, unemployed individuals, housewives, and university students faced a higher risk of being abused. A substantial age difference (≥10 years) in the couple, a history of abortions, and an undesired pregnancy also increased the risk of violence in pregnancy. These findings suggest that prenatal care is an important period for discussing abuse and, in the end, encouraging women to seek help.

A bstract We construct N = 4 D 2 , 1 ; α superconformal quantum mechanical system for any configuration of vectors forming a ∨-system. In the case of a Coxeter root system the bosonic potential of the supersymmetric Hamiltonian is the corresponding generalised Calogero-Moser potential. We also construct supersymmetric generalised trigonometric Calogero-Moser-Sutherland Hamiltonians for some root systems including BC N .

The transition period in football can negatively affect players’ fitness indicators. However, if appropriate training programs are implemented during this period, these effects can be reversed. The purpose of this study was to investigate the effect of a high-frequency exercise program during the transition period on aerobic capacity, isokinetic torque of the lower limbs, jumping ability, and body composition. The transition period was divided into two phases: the first phase lasted two weeks and involved complete rest from exercise, and the second phase lasted four weeks during which the players completed three aerobic-focused training sessions and two maximum strength training sessions per week. A total of 13 young football players (age 17.8 ± 0.7 years, height 1.78 ± 0.07 m, weight 70.3 ± 8.4 kg) participated in the study. A paired samples t-test was applied, and statistical significance was set at p < 0.05. The results showed that players improved their maximal oxygen uptake (VO2 max) after the program (p = 0.037, t = −2.348). The performance in countermovement jump performance and in the isokinetic torque of the right quadriceps showed a decline (p = 0.009, t = 3.112 & p = 0.004, t = 2.299, respectively), while no changes were observed in any other parameter (p > 0.05). The findings suggest that a program with these characteristics can counteract the negative effects typically observed during the transition period. Moreover, with specialized stimuli, improvement may also be observed during the transitional period.

We investigated competitive conditions in global value chains (GVCs) for a period of fifteen years (2000–2014), focusing on sector structure, countries’ dominance and diversification. For this purpose, we used data from the World Input–Output Database (WIOD) and examined GVCs as weighted directed networks, where countries are the nodes and value added flows are the edges. We compared the in-and out-weighted degree centralization of the sectoral GVC networks in order to detect the most centralized, on the import or export side, respectively (oligopsonies and oligopolies). Moreover, we examined the in- and out-weighted degree centrality and the in- and out-weight entropy in order to determine whether dominant countries are also diversified. The empirical results reveal that diversification (entropy) and dominance (degree) are not correlated. Dominant countries (rich) become more dominant (richer). Diversification is not conditioned by competitiveness.

Atrial tachycardias in young patients may portend ominous prognosis. We present the case of a 17‐year‐old male with atrial tachycardia and extensive low‐voltage areas in the right atrium, its treatment, and discuss potential diagnoses.

This paper addresses the gap in the scientific literature regarding construction cost estimates for the construction of underground metro stations. It provides preliminary cost estimation models using linear regression for use by the Greek underground metro public transport authority for planning future extensions to the Athens and Thessaloniki networks. At the same time, it contributes to the body of knowledge by proposing material quantity prediction models and presents a two-stage preliminary cost estimation model for the construction of civil engineering works of underground metro stations. Stage one uses the construction cost budgets of six metro stations in Greece to develop a multilinear regression equation for the prediction of the overall cost for construction of civil engineering works; stage two provides estimates of material quantities using linear regression, key quantity ratios, and artificial neural networks. The data analyzed are from the prior measurements of quantities for the construction of the Chaidari to Piraeus extension of the Athens Metro Line 3. After comparing the actual values of costs and quantities with the corresponding predictions, acceptable discrepancies are observed. All models provide estimates within ±25% discrepancies, which are acceptable at the conceptual planning phase in order to initiate project funding quests.

Background The optimal tumor-free margin width remains controversial and may be inappropriate to investigate without considering differences in the underlying tumor biology. Methods R1 resection was defined as margin clearance less than 1 mm. R0 resection was further divided into 3 groups: 1–4, 5–9, and ≥10 mm. The impact of margin width on overall survival (OS) relative to KRAS status [wild type (wt KRAS ) vs. mutated (mut KRAS )] was assessed. Results A total of 411 patients met inclusion criteria. Median patient age was 58 years (interquartile range, 49.7–66.7); most patients were male ( n  = 250; 60.8 %). With a median follow-up of 28.3 months, median and 5-year OS were 69.8 months and 55.1 %. Among patients with wt KRAS tumors, although margin clearance of 1–4 mm or more was associated with improved OS compared to R1 (all P  < 0.05), no difference in OS was observed when comparing margin clearance of 1–4 mm to the 5–9 mm and the ≥10 mm groups (all P  > 0.05). In contrast, among patients with mut KRAS tumors, all three groups of margin clearance (1–4, 5–9, and ≥10 mm) fared no better in terms of 5-year survival compared to R1 resection (all P  > 0.05). Conclusions While a 1–4 mm margin clearance in patients with wt KRAS tumors was associated with improved survival, wider resection width did not confer an additional survival benefit. In contrast, margin status—including a 1 cm margin—did not improve survival among patients with mut KRAS tumors.

This research investigates the impact of digital math serious educational games (SEGs) on enhancing math skills and motivation, specifically focusing on first-degree equations for students with learning difficulties. A comparative study was conducted among two groups of students with learning disabilities. One group engaged with the digital math serious educational game “Battleship”, while the other received traditional curriculum-based instruction. The study’s dual objectives were to assess the effectiveness of digital math SEGs in improving mathematical performance and to evaluate motivation levels. Additionally, gender differences in performance and motivation were examined to understand how SEGs impact boys and girls differently. Employing an empirical approach, a test comprising standard exercises on first-degree equations, typically encountered in seventh grade, was administered. The Motivated Strategies for Learning Questionnaire (MSLQ) was administered to measure motivation. The research sample consisted of 104 seventh-grade students with learning disabilities, aged 12–13 years, from four public schools in the northern sector of Attica, Greece. The sample was evenly divided into two groups of 52 students each. Data were analyzed using SPSS and Excel. Results indicated that students who engaged with the digital math SEG demonstrated significantly improved math performance compared to their peers who used the standard curriculum book. Interestingly, the control group, which used the standard curriculum book, reported higher levels of motivation, underscoring the complex interplay of motivational factors among students with learning disabilities. Furthermore, the analysis by gender revealed that both boys and girls benefited from SEGs in terms of performance. However, motivation levels were only slightly affected by gender, highlighting the potential of SEGs to support diverse learners.

In the present article, the vibration analysis of laminated composite plates strengthened with multi-walled carbon nanotubes (MWCNTs) is performed, employing the finite element method. Rule of mixtures and the Halpin–Tsai model are utilized to ascertain the elastic properties of the nanocomposite matrix. The effect of random orientation, the curved state, and the agglomeration of carbon nanotubes in the epoxy resin on mechanical properties is investigated. Classical lamination theory is also implemented to theoretically estimate the natural frequencies for validation purposes. Then, the natural frequencies of the laminated composite plates are determined by the numerical method for various parameters involved in the design process. The effect of MWCNTs’ inclusion on the natural frequencies of the carbon nanotube-based laminated plate, taking into account the reformed micromechanical Halpin–Tsai model, is finally investigated. The outcomes of the research are in compliance with experimental values and theoretical evidence available in the bibliography.
