First record of Pontian Monkey Goby, Neogobius fluviatilis (Pallas, 1814) in the Evros River (Greece); Is it an alien species?
The Pontian Monkey Goby,Neogobius fluviatilis (Pallas, 1814), was recorded for the first time in Greece in August 2011. Eight specimens were collected in the Greek-Turkish section of the Evros River, 65 kilometers upstream of its river-mouth. Although the species has been recently discovered in the Tundza, a tributary of the Evros in Bulgaria, it has never before been found in the Evros’ main stem. Although the lower Evros has been poorly researched by ichthyologists, it is unlikely that a conspicuous medium-sized fish would go unnoticed in this river; and, it is therefore suggested to be a probable alien. However, since the Evros basin has had geological connections to the Marmara Sea and Black Sea in the past and it is immediately adjacent to native populations of N. fluviatilis, the species status is categorized as questionable until genetic and morphological studies are completed
Παρέμβαση σε υπάρχον κτίριο- Οι εργασίες αποκατάστασης της Εθνικής Βιβλιοθήκης της Γαλλίας- Διαχείριση των κινδύνων του κτιρίου (αμίαντος, μόλυβδος).
139 σ.Την περίοδο από τον Μάρτιο του 2013 μέχρι τον Αύγουστο 2013 πραγματοποίησα την διπλωματική μου εργασία συμμετέχοντας στην ομάδα διαχείρισης έργου στα πλαίσια των εργασιών για την αποκατάσταση της Εθνικής βιβλιοθήκης της Γαλλίας (Quadrilatère Richelieu).
Η συμμετοχή σε ένα έργο αποκατάστασης είναι ιδιαίτερα ενδιαφέρουσα και ανταποδοτική. Ως μηχανικός στην ομάδα επίβλεψης του έργου, συμμετείχα στην διάγνωση και την πρόληψη των κινδύνων του χώρου του εργοταξίου, ειδικότερα στην παρουσία μολύβδου και αμιάντου.
Μέσα από διαφορετικές αποστολές που έφερα εις πέρας στα πλαίσια του έργου της αποκατάστασης της Εθνικής βιβλιοθήκης της Γαλλίας θα παρουσιάσω τα ζητήματα που αντιμετωπίστηκαν και τις λειτουργικές επιλογές που έγιναν.
Η εξεταστική επιτροπή αποτελούνταν από τους κ.James GILBERT, κ.Kimon Hadjibiro, κ.Tiziana Bardi και κ.Diana TraoréDuring the period from March 2013 to August 2013 I completed my thesis , integrating the project management team on the project of the Rehabilitation of the National Library of France (Quadilatère Richelieu).
Participating in a rehabilitation project is highly rewarding and formative itself. As assistant engineer in the prime contracting team, I participated in the diagnosis and prevention of hazards on site, especially connected to the presence of lead and asbestos.
Through the different missions I undertook joining the rehabilitation project of the “Richelieu Quadrilateral”, I will present the challenges faced and the operational choices taken.Ματθίλδη Α. Αποστόλο

Digital Creativity Support for Original Journalism
The decline in circulations and revenues resulting from the digitalization of news production and consumption has led to a crisis in journalism.Journalists have less time to research, investigate and write original stories, leading to problems for our democratic processes and holding the powerful to account. This paper reports the architecture, features and rationale for new digital creativity support designed to support journalists to discover more original angles onstories. It also summarises the evaluation of the tool’s use in 3 newsrooms
Evaluating The Importance Of Competencies Within Accounting Information Systems Curricula
In International Education Guideline No. 11, the International Federation of Accountants identified the essential information technology (IT) competencies, knowledge, and skills required for entry-level accounting positions. These IT competencies are classified into three categories: (1) IT concepts for business systems (nine competencies), (2) internal control in computer-based business systems (six competencies), and (3) the roles of the professional accountant in information systems (18 competencies classified into three subcategories). In this exploratory study, we surveyed accounting information systems educators about the relative importance of the IFAC competencies to prepare undergraduate students for entry-level accounting positions. The results provide accounting educators with an understanding of current practice regarding the relative emphasis placed on IT competencies in AIS courses. Using this information, the results may be used to guide the allocation of resources within the AIS curriculum
Parents just don't understand: Parent-offspring conflict over mate choice
Previous research reveals that children and parents are not in complete agreement over which traits are most important for the mate of the child. Children tend to prefer traits that suggest genetic quality, whereas parents prefer characteristics that suggest high parental investment and cooperation with the ingroup. Using a sample of parents, mothers (n = 234) and fathers (n =240) the hypothesis was supported; parents perceived characteristics indicating a lack of genetic quality as being more unacceptable to the child, while characteristics indicating a lack of parental investment and cooperation with the ingroup were more unacceptable to themselves. Sex differences between mothers and fathers and sons and daughters were explored
Risk assessment of non-native fishes in the Balkans Region using FISK, the invasiveness screening tool for non-native freshwater fishes
A high level of freshwater fish endemism in the Balkans Region emphasizes the need for non-native species risk assessments to inform management and control measures, with pre-screening tools, such as the Fish Invasiveness Screening Kit (FISK) providing a useful first step. Applied to 43 non-native and translocated freshwater fishes in four Balkan countries, FISK reliably discriminated between invasive and non-invasive species, with a calibration threshold value of 9.5 distinguishing between species of medium and high risk sensu lato of becoming invasive. Twelve of the 43 species were assessed by scientists from two or more Balkan countries, and the remaining 31 species by a single assessor. Using the 9.5 threshold, three species were classed as low risk, 10 as medium risk, and 30 as high risk, with the latter category comprised of 26 moderately high risk, three high risk, and one very high risk species. Confidence levels in the assessments were relatively constant for all species, indicating concordance amongst assessors
Cardiorenal Syndrome: A Glimpse Into Some Intricate Interactions
It is well known that heart and kidney functions are interdependent; primary disorders of one organ have been shown to affect the other organ (organ cross-talk). Over the last decade, growing interest and attention has been drawn to this interaction; the term cardiorenal syndrome (CRS) has been coined and 5 types of CRS have been recognized, whereby a vicious cycle is proposed of acute or chronic dysfunction of either the kidney or the heart which can trigger and aggravate dysfunction of the other organ. This interrelation in which one system negatively influences the other system calls for a closer examination of its pathophysiology, a more systematic approach for the diagnosis and treatment of this syndrome, and more intensive investigation for potential preventive measures. An overview of these complex interactions is herein attempted
Peptidergic modulation of motor neuron output via CART signaling at C bouton synapses
Funding: This work was supported by the General Secretariat for Research and Technology (ARISTEIA II 4257, L.Z.), Fondation SANTE (L.Z.), a Marie Curie Re-Integration Grant (268323, L.Z.), the Hellenic Foundation for Research and Innovation (spinMNALS, 4013, L.Z.) and by a St. Andrews Restarting Research Fund (S.A.S. and G.B.M.). S.A.S. was funded by a Royal Society Newton International Fellowship (NIF/R1/180091) and a Natural Sciences and Engineering Research Council of Canada (NSERC) Postdoctoral Fellowship (NSERC-PDF-517295-2018) and M.M. by the National Scholarship Foundation (IKY).The intensity of muscle contraction, and therefore movement vigour, needs to be adaptable to enable complex motor behaviors. This can be achieved by adjusting the properties of motor neurons, which form the final common pathway for all motor output from the central nervous system. Here we identify novel roles for a neuropeptide, Cocaine and Amphetamine Regulated Transcript (CART), in the control of movement vigour. We reveal distinct, but parallel mechanisms by which CART and acetylcholine, both released at C bouton synapses on motor neurons, selectively amplify the output of subtypes of motor neurons that are recruited during intense movement. We find that mice with broad genetic deletion of CART or selective elimination of acetylcholine from C boutons exhibit deficits in behavioral tasks that require higher levels of motor output. Overall, these data uncover novel spinal modulatory mechanisms that control movement vigour to support movements that require a high degree of muscle force.Publisher PDFPeer reviewe
