Safety implications of higher levels of automated vehicles: a scoping review
No full textAutomated vehicles (AVs) promise to improve road safety, reduce traffic congestion and emissions, and enhance mobility. However, evidence regarding their safety benefits has not been systematically investigated and documented. In this study, we utilise a scoping review approach to investigate and synthesise the existing literature on higher levels of AVs’ safety implications. This aids future relevant studies by identifying the research gaps and reporting the methodological approaches used. The review focused not only on peer-reviewed articles but also on grey literature to provide a comprehensive overview of the current research state. In total, 5724 articles were identified, and 4167 records were screened after duplicates and dual publications removal, from which 27 were found eligible for review. Ultimately, 24 studies met all the inclusion criteria and were considered for the review. The reported evidence was focused on changes in road safety levels after the deployment of AVs in transport networks. The data was extracted and charted by one reviewer using tables to create a descriptive summary of the results and address the scoping review's questions and objectives. In general, the findings suggest that AVs hold the potential to improve the overall safety on roads, although the existing evidence is not mainly based on real data but assumptions regarding vehicles’ capabilities and behaviour. The limited number of studies and the fact that all of them were published or conducted after 2014 indicate that the research on AVs’ safety impacts is just emerging.Accepted Author ManuscriptTransport and Plannin
“Everything somewhere” or “something everywhere”: Examining the implications of automated vehicles’ deployment strategies
No full text“Everything somewhere” or “something everywhere” is the classic dilemma concerning the development and implementation of the future generation of vehicles, i.e., automated vehicles (AVs). Both strategies include diverse policy options that could significantly impact road networks’ planning, design, operation, and utilization. Until now, no significant research has been conducted concerning their implications. In this paper, we aim to examine how ready the current physical infrastructure is by identifying the requirements of each strategy and then applying them in a com-mon type of intersection. The study’s findings demonstrate that AVs’ performance can be affected by policy implementation decisions and adds further weight to the argument of AVs separation or no-separation from no-AVs traffic. Furthermore, the insignificant improvements in traffic performance imply the low readiness of the current road networks in urban areas to accommodate the new technology. This study contributes to determining that research on the readiness of the road infrastructure and the deployment of AVs in urban areas is inevitable. It also identifies that roads’ geometric design can dramatically affect AVs’ operation and the difficulties of implementing dedi-cated lanes in urban areas due to space availability.Transport and Plannin
University students perception of online education: Is engagement enough?
No full textBackground: Universities have halted non-essential services, with many restricting campus-based teaching, and continuing courses through online resources, including (controversially) lab-work. Such technologically enhanced approaches have been proven to have high levels of engagement among university students. Objective: This study focuses on the perception of quality of online learning by first-year university students, between two semesters, amidst the COVID-19 pandemic. Methods: A 24-item questionnaire was designed with Likert response scale. It consisted of general perception questions of academic life and questions specific to the quality of delivery of a specific class. Eighty one eligible students were asked to fill the same questionnaire for each semester. Students’ responses and their grades from the final exams in each semester were compared. Results: Out of 81 eligible students, 75.31% of students responded to the survey. They were less interested in their studies in the second “online” semester (p=0.05). Students expressed dissatisfaction with the quality of online classes (p=0.03). Academic life fulfillment was also affected (p=0.02). Students’ perception of the amount of free time they had between semesters did not change significantly (p=0.16). Students appeared dissatisfied with their active participation during the online class (p=0.007), even though they felt less stressed attending lectures from home (p=0.041). However, they found that workload was bearable and similar between semesters (p=0.83). Students also had significantly more trouble concentrating during online lectures (p<0.001). Students’ grades significantly improved by an average of 1.07 (out of 10) in the final exams at the end of the second semester (p<0.001). Conclusion: These unprecedented circumstances require innovation and cooperation on the part of university programs to maintain rigorous standards of higher education, taking into account students’ evolving perception and needs. © 2021 Apostolos Fyllos,, Asimakis Kanellopoulos, Pavlos Kitixis, Daniel-Valentin Cojocari, Alexandra Markou, Vasileios Raoulis, Nikolaos Strimpakos, Aristeidis Zibi
Greek Surgeon Pavlos Ioannou's Possible Influence on William Halsted's Famous Radical Mastectomy
No full textPavlos Ioannou performed an innovative surgical operation for breast cancer in Vienna University Hospital in 1861. A few years later, after his return to Greece, an operation performed on his closest friend's child, which led to fatal complications, led him to retire from surgical practice. William Halsted travelled to Europe in order to master European surgery, including at Vienna University, and about 20 years later he published his famous method for radical mastectomy, which appears to be identical to Ioannou's operation. This article debates whether Halsted studied Ioannou's method in the archives of Vienna University (and was encouraged by Ioannou's retirement to develop this technique), whether he learned about it through his peers, or whether this was simply a historical coincidence. © The Author(s) 2017
Case study of physiotherapy treatment of a patient with the diagnosis after anterior cruciate ligament surgery
Get PDFTitle: Case study of diagnosis of Anterior Cruciate Ligament surgery Author: Chartosias Pavlos Aim: In the thesis I will be analyzed the function and the mechanism of the knee joint, understanding the kinesiology relation with the Anterior Cruciate Ligament, focusing on the main principles and procedures of the therapy and rehabilitation after one day of surgery. Methods: The therapy included five meetings with the patient during two weeks of clinical practice. The patient had physiotherapy in the morning at the same time. The main goal for the first five days after surgery was to archive as bigger Range Of Motion was possible in the operated knee joint, remove the pain, strength and relax a group of muscles, mobilized any blocked joint and educate the patient how to use the crutches physiological and how can be independent as much possible. Results: Our therapeutic relation between me and the patient was perfect. After five days of therapy my patient archives 50 degrees flexion in the operated knee joint from 0 at the first day. Her doctor was very satisfy, that's why he indicated to her that she is able to go home after the fifth day of my therapy because my therapy was effectiveness and the results were positive. Key words: Anterior Cruciate Ligament, Range Of Motion, Post Isometric Relaxation,..
Theurgy in Dionysius the Areopagite
Get PDFThe present chapter aims at offering insights into Dionysius the Areopagite’s notion of theurgy, both with respect to the metaphysical principles that connect with “θεουργία” and the particular sacramental reality that emerges from it. Pavlos argues that despite the linguistic affinities and terminological appropriations - whether Iamblichean or Proclean - Dionysius’ premises on the matter remain radically different from that of Neoplatonism, both in terms of the sacramental tradition he recapitulates and the wider Christian metaphysical contours he adheres to. Of central importance in the argument is the striking fact that, throughout the Corpus Dionysiacum, “theurgy” is a term exclusively used by the author to refer to the works of Christ in His earthly historical presence, and to the whole divine providential, creative, sustaining, and divinising activity and work of God. Consequently, if for Dionysius a “theurgist” (θεουργός) could not be any human being, but only Christ Himself, the God-Man, Dionysian theurgy aims at the deification of man, which is nothing other than Christ-likeness

Get PDFSmall GTPases of the Rab family not only regulate target recognition in membrane traffic but also control other cellular functions such as cytoskeletal transport and autophagy. Here we show that Rab26 is specifically associated with clusters of synaptic vesicles in neurites. Overexpression of active but not of GDP-preferring Rab26 enhances vesicle clustering, which is particularly conspicuous for the EGFP-tagged variant, resulting in a massive accumulation of synaptic vesicles in neuronal somata without altering the distribution of other organelles. Both endogenous and induced clusters co-localize with autophagy-related proteins such as Atg16L1, LC3B and Rab33B but not with other organelles. Furthermore, Atg16L1 appears to be a direct effector of Rab26 and binds Rab26 in its GTP-bound form, albeit only with low affinity. We propose that Rab26 selectively directs synaptic and secretory vesicles into preautophagosomal structures, suggesting the presence of a novel pathway for degradation of synaptic vesicles
Democracy and taxation
Get PDFIn this paper, the author argues that democracies tend to positively affect the size and composition of tax revenues. His argument is based on the hypothesis that democracies can increase direct taxation, such as income taxes and capital taxes, due to increased compliance of taxpayers and also because there is a diffusion of tax measures between neighboring democratic/autocratic countries. The main theoretical hypothesis is then tested on a dataset that consists of 74 countries over the period 1993-2012. His main explanatory variable will be a dichotomous measure of democracy; but he alters his analysis from previous research by assuming that democracy or autocracy is not an exogenous variable. Instead the author follows the theory of Huntington (The third wave: Democratization in the late twentieth century (Vol. 4), 1991) and the methodology of Acemoglu et al. (Democracy does cause growth, 2014) about regional democratization waves. According to this theory, democratizations occur in regional waves; consequently diffusion of demand or discontent for a political system is easier to happen in neighboring countries due to socio-political and historical similarities. This measure shows him that demand or discontent for a given political system in a geographical area, can in turn influence the power of a country's political regime and subsequently that regime's effect on taxation. The author then uses a two stage least square (2SLS) fixed effects to test our hypothesis. The empirical findings suggest that regional waves of democratization have a positive and statistically significant correlation with democracy, and in turn democracy also has a positive effect on direct taxation as well as the ratio of direct to indirect taxation in the countries of his sample. This result remains the same when several robustness tests are used. Finally when examining the long-run effect of regional waves, the author does not find any evidence of a significant relationship between regional waves of democratization and a country's own regime; however democracy still has a positive effect on direct taxes and tax ratio
A positive deviance approach to eliminate wastes in business processes
No full text
Purpose
The purpose of this paper is to manifest a method that exploits process analytics to discover critical knowledge for a business process. This knowledge eventually answers to the question if process behavior can suggest which activities should be outsourced to get the performance improved.
Design/methodology/approach
The author linked waste sources to process behavioral patterns, and adopted the positive deviance paradigm to highlight compelling behaviors. Various analytic tools (generalized regression, clustering, etc.) were used to provide recommendations.
Findings
By outsourcing small parts of the process, significant process improvement is expected. Evidence-based process analytics can effectively support the relevant decisions.
Research limitations/implications
The author had no access to the relevant policy makers (process owners).
Originality/value
The author proposed an operationalization of concepts that connects process behavior to waste sources. The author presented the use of positive deviance as a guide for waste elimination projects.
