Aσύγχρονες ψηφιακές συζητήσεις στην εκπαιδευτική διαδικασία
Authors: Κεσσανίδης Στέλιος , Παπασταματίου Νίκος
Published: June 2016

Η τεχνολογία μπορεί να ενισχύσει τη διδακτική και μαθησιακή διαδικασία αν χρησιμοποιηθεί κατάλληλα. Μια μορφή τεχνολογίας στην οποία η εκπαιδευτική κοινότητα έχει δώσει δυσανάλογα μικρή σημασία είναι οι χώροι ασύγχρονων διαδικτυακών συζητήσεων. Τα δικτυακά forums (fora) είναι επίσης γνωστά σαν discussion boards ή message boards. Οι χώροι αυτοί επιτρέπουν στους χρήστες να αλληλεπιδρούν, να ανταλλάσσουν ιδέες, απόψεις και υλικό που σχετίζεται με ένα θέμα και το οποίο -με τη σειρά του- σχετίζεται με τη θεματική περιοχή του δικτυακού τόπου. Η μάθηση μέσα από τα διαδικτυακά forums είναι ένα σημαντικό εκπαιδευτικό εργαλείο. Εξετάζουμε τις εκπαιδευτικές-παιδαγωγικές δυνατότητες των forums καθώς και τα χαρακτηριστικά ενός καλού διαδικτυακού forum.

Στα πλαίσια της παρούσας έρευνας επιχειρείται η αξιολόγηση του προγράμματος εξ Αποστάσεως Εκπαίδευσης Εκπαιδευτών Ενηλίκων του Ινστιτούτου Διαρκούς Εκπαίδευσης Ενηλίκων (Ι.Δ.Ε.Κ.Ε) της Γενικής Γραμματείας Διά Βίου Μάθησης (Γ.Γ.ΔΒ.Μ). Το πρόγραμμα βασίζεται στη λειτουργία ενός συστήματος (πλατφόρμας) διαχείρισης μάθησης με ηλεκτρονικά μέσα (Learning Management System, LMS) το οποίο υποστηρίζεται από το Κέντρο Διά Βίου Μάθησης από Απόσταση (ΚΕ.Δ.Β.Μ.ΑΠ) του Ι.Δ.Ε.Κ.Ε. Με βασικό μεθοδολογικό εργαλείο ένα κατάλληλα δομημένο ανώνυμο ερωτηματολόγιο, απευθυνόμενο στους εκπαιδευόμενους που παρακολούθησαν το πρόγραμμα στην Περιφέρεια Κρήτης, επιχειρείται μια πρώτη συνοπτική αποτίμηση του προγράμματος. Ανάμεσα στα κυριότερα αποτελέσματα, αναδεικνύεται η θετική στάση των εκπαιδευομένων απέναντι στο πρόγραμμα. Θέση κλειδί φαίνεται να κατέχουν ο εκπαιδευτής καθώς και οι διά ζώσης εκπαιδευτικές συναντήσεις. Στα αρνητικά στοιχεία, οι εκπαιδευόμενοι επισημαίνουν αρκετά από τα μειονεκτήματα της πλατφόρμας, όπως η αδυναμία αποθήκευσης του πολυμεσικού υλικού και η αδυναμία έναρξης συζήτησης από τον εκπαιδευόμενο-χρήστη. Αρνητικά σχόλια εστιάστηκαν επίσης στην ασαφή διατύπωση των υποχρεωτικών εργασιών καθώς και στην ανεπάρκεια του παρεχόμενου ηλεκτρονικού υλικού για την εκπόνηση αυτών των εργασιών. Γενικότερα, το υπό  μελέτη πρόγραμμα, όπως και για κάθε πρόγραμμα επιμόρφωσης ενηλίκων, είναι σημαντικό να λαμβάνει υπόψη του τις βασικές αρχές της εκπαίδευσης ενηλίκων και την αυτοπροσδιοριζόμενη και ενεργό συμμετοχή τους στην αναγνώριση των εκπαιδευτικών αναγκών τους.

Σε ένα εκπαιδευτικό σχήμα εξ αποστάσεως εκπαίδευσης η διαδικασία της μάθησης και διδασκαλίας αποτελεί για το εκπαιδευόμενο μια «μοναχική» πορεία, καθώς ο παράγοντας «απόσταση» προκαλεί αντικειμενικά μια σειρά από δυσκολίες. Για αυτό το λόγο, επιβάλλεται ο σχεδιασμός ενός ποιοτικού διδακτικού υλικού που θέτει σε χρήση ευέλικτα εκπαιδευτικά εργαλεία ενεργητικής αλληλεπιδραστικής μάθησης, επιτρέποντας στο φοιτητή να μάθει αυτενεργώντας. Στην ανοικτή και εξ αποστάσεως εκπαίδευση το εκπαιδευτικό υλικό έχει καθοριστική σημασία τόσο στην εκπαιδευτική διεργασία όσο και στην ολοκλήρωση των σπουδών του φοιτητή. Αποτελεί τον κύριο φορέα της γνώσης και αναπληρώνει την απουσία του διδάσκοντα. Η κύρια μορφή του εκπαιδευτικού υλικού είναι το έντυπο υλικό. Όμως, τα τελευταία χρόνια αυτό συμπληρώνεται από μια μεγάλη ποικιλία οπτικοακουστικού και λογισμικού υλικού, το συμπληρωματικό υλικό.

Στην παρούσα εργασία γίνεται μια προσπάθεια να αναδειχθούν οι απόψεις των ΣΕΠ και του ΔΕΠ της Θεματικής Ενότητας «Ανοικτή και εξ αποστάσεως Εκπαίδευση» και μιας Υποψήφιας Διδάκτωρ του Ελληνικού Ανοικτού Πανεπιστημίου για το πολυμορφικό ΕξΑΕ εκπαιδευτικό υλικό.

Σκοπός ήταν να διερευνήσει το σχεδιασμό και την ανάπτυξη ενός νέου πολυμορφικού ΕξΑΕ εκπαιδευτικού υλικού στην ΘΕ Αεξαε του ΕΑΠ. Στη μελέτη συμμετείχαν ο ΔΕΠ, πέντε ΣΕΠ της Θεματικής Ενότητας  για το Ακαδημαϊκό έτος 2009-2010 και μία υποψήφια διδάκτωρ του ΕΑΠ, ως συμμέτοχοι σε ατομικές συνεντεύξεις. Τα αποτελέσματα της έρευνας  δείχνουν την ανάγκη για άμεσο σχεδιασμό και δημιουργία πολυμορφικού ΕξΑΕ διδακτικού υλικού.
Business English and Business French:a comparative analysis of teaching strategies and firms' needs.
Authors: BENZO VERONICA , DI GREGORIO GIUSEPPINA
Published: June 2016

Following T. Dudley-Evans’ suggestions, in order to analyse languages for specific purposes, it is possible to argue that present teaching experience is characterized by certain common aspects, such as teachers’ insufficient extra-linguistic knowledge; lack of adequate teaching materials; learners’ different levels of linguistic competence and lack of motivation. Futhermore, Business Languages imply an additional aspect to be investigated, a sort of ‘side effect’: rapid changes in the market determine a necessity, that of naming new features and conditions, hence the question of word-formation and transparency arises. Moving from an analysis of language curricula at the University of Catania, Department of Business Economics, this paper will seek to explore adopted teaching methods in order to point out the importance of integrating language and content, as stated by Fortanet-Gómez and Räisänen. The study’s diachronic and synchronic evaluation of the applied approaches will lead to suggestions in the design of modules, taking into account the role played by both Business English and Business French, in terms of teaching implications and job opportunities. The main aim is to provide a potential answer to the following question: To what extent are companies aware of the need to invest in languages, intercultural and interpreting skills, and the management of linguistic diversity?

 
Monolingualism or multiple versions for Erasmus+ Guidelines? Incompatibilities and utopia.
Authors: HATZIDAKI ELISA
Published: June 2016

Since the ECSC Treaty signed in Paris in 1951, marking the beginning of the commun destiny of the first international integration organization until the most recent decisions, such as the single currency or the immigration policies, it is a matter of fact that European Union progresses only with harmonious dialogue and joint actions, built on mutual respect of others’ differences. Nowadays, in the rapidly changing societies, financial concurrence and geopolitical stakes together with arrogance, or dominance, often outweigh the plurilingual communication, thereby leading to worries about linguistic equality within the Union; hence, the subject of the present stydy. Communication in this polyglottic supranational union should be based on an equal pattern, without what the impact of English as lingua franca[1] may be contested and criticised. This combined with the fact that translations are not fully compatible with the English text, implies that European Union does not always resonate at the same frequencies.

Russia’s foreign language market and some innovative aspects of the university curricula
Authors: REINHOLD NATALYA
Published: June 2016

Basing herself on the local statistics, the author draws an outline of the current state of things in the Russian foreign language (FL) and translation/interpreting (T/I) job market. In particular, she focuses on the issue of compatibility of the market and business demands for the FL and T/I graduates with the respective degree programmes at the Russian institutions of higher learning. Her findings bring up a patchy picture of the state of things in tertiary education (e.g. the out-of-date curricula, the old-fashioned courses, etc. at some institutions, and the dynamic, progressive and innovative developments at other schools). It is on the latter that she focuses primarily. Her case study is the MBA programme in FL/TI, and Business, which was designed at the RSUH institute for the in-service continuing education.
Developing a foreign language policy in Greek higher education (HE): striving between Scylla and Charybdis.
Authors: TSELIGKA THEODORA
Published: June 2016

The present study analyses foreign language (FL) policy in Greek higher education (HE) taking into consideration the multiple interrelated factors that development and implementation of a successful FL policy hinges on. A brief overview is presented of European initiatives that have contributed significantly to the promotion of language learning, multilingualism and the harmonization of university language policies.  This was considered necessary so as to lay the context for the presentation of the practices documented in the Greek HE arena, with specific examples provided from Greek institutions.  To address the aims of this research project, the state legislation relevant to FL issues in HE is examined and discussed, as it unavoidably influences and mirrors observed trends and priorities in language education.  Finally, extensive data is analysed from five Greek HE institutions and their FL instructors, with regard to language practices implemented, programmes of study, instructors’ professional status, etc.  The results of this analysis show that great effort and extensive co-operation among all stakeholders is still required in devising a holistic FL policy in Greek HE, to which end this paper also offers some useful recommendations.

Genetic differentiation among Parastichopus regalis populations from Western Mediterranean Sea: potential effects of its fishery and current connectivity.
Authors: MAGGI C. , GONZÁLEZ-WANGÜEMERT M.
Published: June 2016

Parastichopus regalis (Cuvier, 1817) is the most expensive seafood product on the catalonian market (NE Spain), with prices around 130 €/Kg (fresh weight). Despite its ecological and economic importance, biological and genetic information on this sea cucumber species is scarce. We provided the first insight on the genetic structure of P. regalis using sequences of cytochrome oxidase I (COI) and 16S genes, as well as a morphological description of its populations. Individuals were collected in six locations along the Spanish Mediterranean coast, including an area under fishery pressure (Catalonia). We found high haplotype diversity and low nucleotide diversity for both genes, with higher levels of genetic diversity observed on COI gene. Population pairwise fixation index (FST), AMOVA and correspondence analysis (CA) based on COI, revealed significant genetic differentiation among some locations. However, further analysis using nuclear markers (e.g. microsatellites) would be necessary to corroborate these results. Moreover, the genetic and morphological data may indicate fishery effects on the Catalonian population with decrease of the size and weight average and lower genetic diversity compared to locations without fishery pressure. For an appropriate management of this species, we suggest: 1) an accurate assessment of the stocks status along the Spanish coasts; 2) the study of the reproductive cycle of this target species and the establishment of a closed fishery season according to it; 3) the founding of protected areas (i.e. not take zones) to conserve healthy populations and favour the recruitment on the nearby areas.

The Collective Article ‘New Mediterranean Biodiversity Records’ of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided in two parts, for records of alien and native species respectively. The new records of alien species include: the red alga Asparagopsis taxiformis (Crete and Lakonicos Gulf) (Greece); the red alga Grateloupia turuturu (along the Israeli Mediterranean shore); the mantis shrimp Clorida albolitura (Gulf of Antalya, Turkey); the mud crab Dyspanopeus sayi (Mar Piccolo of Taranto, Ionian Sea); the blue crab Callinectes sapidus (Chios Island, Greece); the isopod Paracerceis sculpta (northern Aegean Sea, Greece); the sea urchin Diadema setosum (Gökova Bay, Turkey); the molluscs Smaragdia souverbiana, Murex forskoehlii, Fusinus verrucosus, Circenita callipyga, and Aplysia dactylomela (Syria); the cephalaspidean mollusc Haminoea cyanomarginata (Baia di Puolo, Massa Lubrense, Campania, southern Italy); the topmouth gudgeon Pseudorasbora parva (Civitavecchia, Tyrrhenian Sea); the fangtooth moray Enchelycore anatine (Plemmirio marine reserve, Sicily); the silver-cheeked toadfish Lagocephalus sceleratus (Saros Bay, Turkey; and Ibiza channel, Spain); the Indo-Pacific ascidian Herdmania momusin Kastelorizo Island (Greece); and the foraminiferal Clavulina multicam erata (Saronikos Gulf, Greece). The record of L. sceleratus in Spain consists the deepest (350-400m depth) record of the species in the Mediterranean Sea. The new records of native species include: first record of the ctenophore Cestum veneris in Turkish marine waters; the presence of Holothuria tubulosa and Holothuria polii in the Bay of Igoumenitsa (Greece); the first recorded sighting of the bull ray Pteromylaeus bovinus in Maltese waters; and a new record of the fish Lobotes surinamensis from Maliakos Gulf.

Published: June 2016

Fish assemblage in a surf zone of the southern Tyrrhenian Sea was investigated for the first time. Samples were collected during four surveys by a modified beach-seine, from June 2005 to May 2006. Overall, 42 species belonging to 19 families were recorded. Among them, Sardina pilchardus showed the highest abundance values, while Mugilids (Oedalechilus labeo and Liza aurata) were the most frequently caught species. The fish community was dominated by pelagic and gregarious species using this habitat as a foraging ground and recruitment area. Juveniles and early adults made up the largest proportion of the ichthyofauna. Fishes inhabiting the surf zone were mainly strictly benthic invertebrate feeders and invertivorous/piscivorous fish; strictly planktivorous were represented by few species but strongly dominant in terms of catch per unit effort; strictly piscivorous fish were poorly represented. Fish composition varied over the study period with the greatest abundance in May and December, and the highest richness and diversity in October.

Published: June 2016

An oceanographic survey was carried out during the summer of 2009, from June 25 to July 3 in the Gulf of Gabes. The study area is characterized by a wide continental shelf.A plankton sampling scheme was carried out to study the structure of the larval fish assemblages that characterizes the surface mixed layer, and to assess the influence of the environmental parameters on their spatial distribution.A total of 36 taxa were identified, 3 classified to the level of genus, 5 to family and 28 to species. The majority of identified fish larvae belonged to demersal species, mainly picarel Spicara smaris (23.76% of the total larval fish abundance), followed by red mullet Mullus barbatus (14.92%) and several species of the Sparidae family (9.15%). Small pelagic species as Sardinella Sardinella aurita and European anchovy Engraulis encrasicolus were also abundant (27.75 %) and dominated the fish larvae community in offshore stations. Five large pelagic species were found among the larvae, including bullet tuna Auxis rochei, Atlantic black skipjack Euthynnus alletteratus, albacore Thunnus alalunga, swordfish Xiphias gladius and the highly migratory Atlantic bluefin tuna Thunnus thynnus. All these apex predator species appear in 38.5% of the sampling stations and contribute about 7.9% of the total larval catches. The larval fish assemblage of the Gulf of Gabes is predominantly composed of neritic species in correspondence with the shallow depths of the study area. Canonical Correspondence Analysis (CCA) showed that larval distributions were mainly conditioned by depth. However, other factors, like hydrographic processes, play also a very important role in shaping the spatial pattern of larval fish distribution.
Trawling disturbance effects on the trophic ecology of two co-generic Astropectinid species
Authors: MANGANO M. C. , KAISER M. J. , PORPORATO E. M.D. , LAMBERT G. I. , SPANÒ N.
Published: June 2016

Physical disturbance by trawling can have both negative and positive effects on populations of scavenging benthic organisms. In the present study the impact of fishing activity on feeding behaviour of the two Astropectinids, Astropecten bispinosus and A. irregularis, was assessed based on stomach contents analysis. The study was carried out along trawled seabed highlighting the positive response of the two facultative scavengers to carrion generated by trawl disturbance. Furthermore, there was greater food specialization in areas that were more heavily exploited by trawling. This specialisation could be linked to the availability of certain prey that results from the passage of fishing gears across the seabed. Interestingly, differences between the two species analysed have been highlighted in term of population dynamic, feeding rate, diet composition and diet diversity, testifying their capacity to coexist in the same fishing grounds.
Diets of peracarid crustaceans associated with the orange coral Astroides calycularis in southern Spain

Published: June 2016

The endangered and Mediterranean endemic orange coral (Astroides calycularis) hosts an important macrofaunal assemblage. The gut contents of the main peracarids associated with the orange coral were analysed. In total 161 specimens belonging to 11 species and 9 families were examined on the southern coast of the Iberian Peninsula. The gut content study was carried out introducing the specimens of each species in Hertwig’s liquid. The analysis revealed that the peracarid species associated with A. calycularis had different feeding strategies and their main food source was detritus. The results highlight that peracarids may depend on the host and the detritus that the coral produces.

Published: June 2016

In this study, Holothuria tubulosa Gmelin 1791 was investigated from April 2013 to March 2014 in the Dardanelles Strait, to outline the morphological characteristics, reproductive patterns and the relationship between population characteristics and environmental parameters. Between 15 and 30 individuals of this species were sampled monthly from three stations. There was a negative allometry between length and weight, being gutted weight the most reliable measurement for this species. Reproductive patterns of the species were identified the first time for Turkish coasts. By macroscopic examination of the gonads, smallest sizes (gutted length) were measured as 8.4 and 8.1 cm for female and male, respectively. Sex ratio was calculated as 1: 1.1 with differences between seasons. The reproduction of sea cucumbers occurred between August and September after Gonadosomatic Index (GSI) values reached their maximum in July. The species was found down to 10 m depth with a population density of 0.21 / m2, which was rather low compared to previously reported values for Mediterranean populations of this species. There was a high positive correlation between population density and GSI of the species. The highest population density was observed where the largest sea grass meadows are found.
Influence of phytoplankton taxonomic profile on the distribution of total and dissolved dimethylated sulphur (DMSx) species in the North Aegean Sea (Eastern Mediterranean)
Authors: MARA P. , PSARRA S. , TSELEPIDES A. , ELEFTHERIOU A. , MIHALOPOULOS N.
Published: June 2016

The distribution of total and dissolved forms of DMSP and total DMSO was surveyed during two sampling cruises conducted in September 2003 and July 2004 in the North Aegean Sea. During the first cruise the surface concentrations of DMSPt, DMSPd and DMSOt in the coastal group of stations ranged from 20.92 to 23.71 nM, 15.46 to 15.53 nM and 14.90 to 18.73 nM respectively, while in the offshore group the mean concentrations were 27.41 nM (DMSPt) and 14.66 nM (DMSOt). Concerning the phytoplankton assemblage it was dominated by dinoflagellates. During the second cruise, the surface DMSPt, DMSPd and DMSOt concentrations in the coastal group were not significantly changed compared to the first cruise, while the offshore group presented more elevated values (DMSPt: 33.52 nM; DMSPd: 18.78 nM; DMSOt: 36.49 nM). Interestingly the vertical distribution and the phytoplankton abundance in this cruise were changed, with diatoms being the dominant group in the study area. On both cruises statistically significant correlations between small-sized dinoflagellates (≤ 20 μm) as well as coccolithophores and the concentrations of DMSx compounds obtained, suggesting the importance of the above phytoplankton groups in the production and distribution of the these sulphonic forms. At the same time, no significant correlations were observed between DMSx and diatom species. The strong correlation of DMSx species with the group of dinoflagellates coupled with their decorrelation with Chl-a may serve as indirect evidence of heterotrophic forms dominating dinoflagellate taxa thriving in the area during the stratified period.
Spatial and temporal distributions of the sponge fauna insouthern Italian lagoon systems

Published: June 2016

The present work focused on the taxonomic composition, spatial distributions, and temporal distributions of the sponge fauna from the main lagoon systems of southern Italy: Lesina, Varano, Taranto, Alimini, Faro, Ganzirri, Tindari and Marsala. Overall, 62 sponge species were recorded, belonging to the classes Demospongiae (52 species), Calcarea (8) and Homoscleromorpha (2). All the lagoon systems studied hosted sponges, even if with marked differences. Species richness varied from one (Lesina) to 45 (Marsala). A large number of the species recorded during this study (52%) was found only at a single site, whereas a species only (Halichondria (H.) panicea) was present in all the environments studied. Sponges colonised all available substrates. Salinity was the ecological factort hat best explained the spatial distribution of sponges, even though the wide heterogeneity of sponge assemblages, strongly suggests an important role of stochastic factors acting on pre- and post-settlement phases. Comparison of the present data with lists available from the literature shows that sponge assemblages from most of the studied lagoons were quite persistent. However, in some of the lagoons remarkable extinction processes, probably related to massive and prolonged anthropogenic pressures, have contributed to large changes in the sponge patterns.
MASSIVE FISH MORTALITY IN ISMARIDA LAKE, GREECE: IDENTIFICATION OF DRIVERS CONTRIBUTING TO THE FISH KILL EVENT
Authors: KOUTRAKIS E. , EMFIETZIS G. , SYLAIOS G. , ZOIDOU M. , KATSIAPI M. , MOUSTAKA-GOUNI M.
Published: June 2016

During the end of August 2013, a massive fish mortality occurred in Ismarida Lake, a small and shallow system of Northern Greece, where approximately 10-18 tons of euryhaline fish died. This study attempts to describe the event of this fish kill or Massive Fish Mortality (MFM) that occurred in Ismarida Lake during the night of August 28, 2013, and to identify the possible drivers that may have triggered this event. A combined hydrographic, ichthyological and phytoplankton survey were carried out along with a toxicological analysis. Finally, the study proposes both short-term and long-term measures for the management of both quality and quantity of the water (ground and surface) resources in the broader basin of Ismarida Lake.
Influence of Dardanelles outflow induced thermal fronts and winds on drifter trajectories in the Aegean Sea

Published: June 2016

The data provided by 12 drifters deployed in the Northern Aegean Sea in the vicinity of the Dardanelles Strait in August 2008 and February 2009 are used to explore the surface circulation of the basin and the connectivity to the Black Sea. The drifters were deployed within the Dardanelles outflow of waters of Black Sea origin in the Northeastern Aegean. Thanks to the particular choice of the drifter deployment positions, the data set provides a unique opportunity to observe the branching behaviour of the surface currents around Lemnos Island. Such pathways were notpossible to study with previous drifter deployments that were far from the Dardanelles Strait. In addition, the drifter tracks covered the Aegean basin quite thoroughly, mapping major circulation features and supporting the overall general circulation patterns described by previous observational and modelling studies. The collected data display cases in which drifters are driven by winds and thermal fronts. Wind products were used to estimate the influence of the atmospheric forcing on the drifter trajectories. Satellite sea surface temperature images were connected to the drifter tracks, demonstrating a high correlation between the remote and in situ observations. The waters of Black Sea origin were traced all the way to the Southern Aegean, establishing a strong connectivity link between the Aegean and Black Sea basins.
Climate change and Mediterranean seagrass meadows: a synopsis for environmental managers

This synopsis focuses on the effects of climate change on Mediterranean seagrasses, and associated communities, and on the contribution of the main species, Posidonia oceanica, to the mitigation of climate change effects through its role of sequestering carbon dioxide. Whilst the regression of seagrass meadows is well documented, generally linked to anthropogenic pressures, global warming could be a cause of new significant regressions, notably linked to the introduction of exotic species, the rise of Sea-Surface Temperature (SST), and relative sea level. Seagrass communities could also be affected by climate change through the replacement of seagrass species having high structural complexity by species of lower complexity and even by opportunistic introduced species. Although it is currently very difficult to predict the consequences of these alterations and their cascade effects, two main conflicting trends in the functioning of seagrass ecosystems that could occur are acceleration of the herbivore pathway or of the detritivore pathway. The mean net primary production of the dominant species, Posidonia oceanica, is relatively high and can be estimated to range between 92.5 to 144.7 g C m-2 a-1. Around 27% of the total carbon fixed by this species enters the sedimentary pathway leading to formation, over millennia, of highly organic deposits rich in refractory carbon. At the Mediterranean scale, the sequestration rate might reach 1.09 Tg C a-1. The amount of this stored carbon is estimated to range from 71 to 273 kg C m-2, which when considered at the Mediterranean scale would represent 11 to 42% of the CO2 emissions produced by Mediterranean countries since the beginning of the Industrial Revolution. The greatest value of the P. oceanica ecosystem, in the context of mitigation of global climate change, is linked to this vast long-term carbon stock accumulated over the millennia, and therefore, efforts should be focused on preserving the meadows to keep this reservoir intact.

Published: June 2016

Production practices of IF (interstitial free) steel grades intended for the most qualitatively demanding automotive applications calls for their continuous optimization. Precise control of steelmaking operation conditions leads to a minimization of clogging issues during their casting, but is also related to surface quality imperfections of finished material. With the aim to study the impact of RH degasser practices on cleanliness of the IF steel grades, the influence of heat chemical reheating was verified. While detailed analyses confirmed overall worse results and a higher presence of specific nonmetallic particles on steel samples collected from such treated heats, the limited reheating practice did not seem detrimental.

Kumaun Himalaya is one of the unique systems rich in indigenous traditional knowledge and culturally strong. In the present study, qualitative and quantitative data were on agro-biodiversity through field and literature survey. Altogether, 160 plant species belonging to 117 genera and 57 families were recorded. In addition, a large number of land races, varieties and wild relatives are also being used. Cultivation of these crops is mainly of subsistence in nature rather than for commercial purposes. Due to a number of reasons, the area under traditional crops is declining in Kumaun Himalayan region but many of the crop varieties are still conserved because of their socio-cultural and religious values. The human population has increased over time forcing farmers to change their cropping patterns, for example, replacement of mixed cropping to mono-cropping and switching over to cash crops. This has adverse implications on traditional agro-biodiversity of the region. There are both local and global advantages in supporting a dynamic traditional system of agro-biodiversity management. Therefore, promotion and conservation of agro-biodiversity should be done through sustainable use and on- farm and off- farm management.

In a previous work, Lantana camara L. (lantana) plants grew in three different light environments after treatments with drenched-applied paclobutrazol to test their potential to give easthetically attractive products (small plants with increased flowering). Nevertheless, no information is known with regard to the bioclimatic conditions of the aforementioned light environments (0%, 28% and 66% shadings). Therefore, the present work determined their bioclimatic conditions in summer (hot period of the year) and especially August, with the use of a widely used index, the thermohygrometric index, in a glasshouse in Attica, Greece. Average thermohygrometric index values were used for the evaluation of bioclimatic conditions and the relative frequencies of the different classes of thermohygrometric index were calculated on a two-hour basis for each examined shading. From the results of this study, the environment with the full light regime (0% shading) provided less favorable bioclimatic conditions compared to other examined light regimes (28% and 66% shadings), during the daytime period (08:00-20:00 h). Between 28% and 66% shadings, more favorable bioclimatic conditions were established at 66% shading for the same period. The nighttime period (22:00-06:00 h) was characterized as more friendly, bioclimatically, compared to the respective daytime period, irrespective of the examined light regime. Among the three studied shadings in nighttime period, the more favorable bioclimatic conditions were noticed in the low light regime (66% shading). The less favorable bioclimatic conditions were detected at the plot with 28% shading, compared to other shadings at the aforementioned period. The findings of this study could be beneficial for the planning of the work in other plant cultivations inside a glasshouse the hot period of the year.

The research aims to develop a controlling intangible assets model on secondary irrigation system management. The method used in this research consists of three stages: model development, collecting the data, and testing of models. Two stages were done in model development; the first stage was building the model of controlling intangible assets in irrigation system management using neuro-fuzzy system, which had three sub models: (i) knowledge management, (ii) intangible assets, and (iii) performance of irrigation system. The second stage was evaluating the model at Molek irrigation system in Malang, East Java. Data collection were done by questionnaire and interview on employees of Kepanjen Irrigation Office. Data analysis was done using Adaptive Neuro Fuzzy Inference System. The model was evaluated using correlation coefficient, Mean Absolute Percentage Error and Root Mean Square Error. The result indicated that the model of controlling intangible assets in irrigation system management could predict the intangible assets and performance of irrigation system. The model linked to knowledge management, intangible assets and performance of irrigation system. Knowledge management was described into four main components: (i) learning organization, (ii) principle of organization, (iii) policies and strategies of organization, and (iv) information and communication technology which control intangible assets on irrigation system. Intangible assets consist of moral intelligence, emotional intelligence, creative attitude, and institutional culture which controlling effectiveness of irrigation system. It can be concluded that the controlling model of intangible assets irrigation systems which built with the principles of neuro-fuzzy can predict the intangible assets and irrigation system performance

Chrysanthemum flowers are a main income source of surrounding communities of Hargobinangun. Hargobinangun became the main cut flower's supplier to the province of Yogyakarta before the Merapi’s eruption. However, due to the shortage of cut flower production, currently those have to be imported from other areas such as Cipanas, Pasuruan and Malang. One of the production’s obstacles is the environmental damage. Soil in planting area was covered by thick sand and volcanic ash from Mount Merapi eruption. Research and transfer of technology has been carried out by R & D team of Universities Pembangunan National “Veteran” Yogyakarta (UPNVY). The technologies of amelioran's addition to the soil in the disaster areas was using simple techniques, inexpensive and available materials from surrounding farmers site, such as manure, bamboo leaf litter and garden’s compost. The materials were initially fermented by using PGPR that were produced by R & D UPNVY. In addition, application of horticultural mineral oil (HMO) was performed to avoid white rust infection. The results showed the increase of soil fertility and plant growth significantly which is expressed by the increase of plant height, stem diameter, and leaf area after application of ameliorant. The quality of cut flowers also increased in the form of the increase of flower diameter, and numbers of ribbon flower. The application at the farm level showed that farmers have no difficulty in using Enkas, although it is still necessary to conduct further training and mentoring to increase the success rate.
Survey and Identification of Root-Knot Nematodes Associated with Brinjal Crops in Fatehabad, Agra
Authors: Yadav Bindhya , Kumar Sanoj
Published: June 2016

A survey was conducted over a period of one and half year to estimate the occurrence of root-knot nematode disease on brinjal crops in five selected localities in and around Fatehabad, Agra. Our survey indicates that brinjal crops grown in the selected localities were heavily infested with root-knot nematodes. Highest frequency of disease occurrence in which almost all the roots have knot-like appearance (>85%) was reported from Firozabad Road area. Other localities were also having the significant infestations and these were reported as 80%, 78%, 65%,62% respectively. To access the damage caused by root-knot nematodes in brinjal crop, Meloidogyne gall index and its egg-mass index were calculated and these were found in the range of 2-5. An increased gall index and egg-mass index point to heavy infection on selected crops. Sampled crop showed the significant presence of Meloidogyne javanica. However, there were other species of root-knot nematode as mixed population was also reported. Other species of the root-knot nematodes which were reported in this survey was M. incognita. This survey indicates that the M. javanica is a frequently occurring population in brinjal field infested with root-knot disease.

A Gene Selection Approach based on Clustering for Classification Tasks in Colon Cancer
Authors: Castellanos Garzón José Antonio , Ramos González Juan
Published: June 2016

Gene selection (GS) is an important research area in the analysis of DNA-microarray data, since it involves gene discovery meaningful for a particular target annotation or able to discriminate expression profiles of samples coming from different populations. In this context, a wide number of filter methods have been proposed in the literature to identify subsets of relevant genes in accordance with prefixed targets. Despite the fact that there is a wide number of proposals, the complexity imposed by this problem (GS) remains a challenge. Hence, this paper proposes a novel approach for gene selection by using cluster techniques and filter methods on the found groupings to achieve informative gene subsets. As a result of applying our methodology to Colon cancer data, we have identified the best informative gene subset between several one subsets. According to the above, the reached results have proven the reliability of the approach given in this paper.

Mechanisms of Resistance to Quinolones and Epidemiological Significance of Salmonella spp.
Authors: Velhner Maja
Published: June 2016

Bacteria develop resistance to antimicrobial agents by a number of different mechanisms. The resistance to (fluoro)quinolones in Salmonella is of particular importance especially if therapy in humans is required. For decades there has been a significant interest in studying the biology of Salmonella because these bacteria are among the leading causes of foodborne illnesses around the globe. To this date, two main mechanisms of quinolone resistance have been established: alteration in the targets for quinolones, decreased accumulation inside bacteria due to impermeability of the membrane and/or an over expression of the efflux pump systems. Both of these mechanisms are chromosomally mediated. Furthermore, mobile elements have been described carrying the qnr gene which confers resistance to quinolones. The plasmid encoded QNR proteins belong to the pentapeptide repeat family of proteins. The plasmid mediated quinolone resistance (PMQR) is often associated with the resistance to beta lactam antibiotics. It was noticed that PMQR is backing up chromosomal mutations for quinolone resistance, hence becoming an important resistance mechanism worldwide. Even with our knowledge expanding over the years, it is not possible to predict how bacteria will respond in the future, if they are exposed to new external challenges. The possibility that they will find a way to survive by introducing new mutations or by exchanging mobile genetic elements and subsequently developing resistance to survive in the environment should not be underestimated.

Histopathological examination, grading, immunohistochemical staining and molecular genetic examinations are the proposed criteria that should be used for cutaneous mast cell tumors (CMCTs) classification. The presence of aberrant CD117 expression and mutations of the c-kit proto-oncogene could be an indicative parameter for final histological grading. Determination of the connection between the localization of KIT receptor expression and the histological grade of CMCTs without c-kit proto-oncogene mutations was the main goal of this study. The study included twenty four CMCTs and six control skin samples from 30 dogs of different ages, breed and sex. Formalinfixed and paraffin-embedded tissue samples were stained with hematoxylin-eosin and toluidine blue and immunohistochemically tested for CD117 expression. DNA was extracted from the same paraffin blocks and subsequent polymerase chain reaction amplification was performed using PE1 and PE2 primers. Degree of malignancy was determined based on the presence of mitotic figures, multinucleated cells, bizarre nuclei and karyomegaly in 10 high power fields. Based on histological features, fourteen of 24 CMCTs were of a high histological grade, while ten were classified as a lowgrade malignancy. CD117 cytoplasmic expression was observed in nine of fourteen high-grade malignancy CMCTs, which confirms the link between the aberrant CD117 expression and increased cell proliferation.
Stopping the “pendulum effect” in CLIL research: Finding the balance between Pollyanna and Scrooge
Authors: Pérez Cañado María Luisa
Published: June 2016

This article examines the appearance of the “pendulum effect” in the CLIL research arena and makes a case for a balanced, disinterested, and methodologically sound approach to continue driving the CLIL agenda forward. It is written as a response to the steady stream of criticism to which CLIL research has recently been subjected and which is primarily embodied by Bruton (Is CLIL so beneficial, or just selective? Re-evaluating some of the Research.System39. 523–532 (2011b), CLIL: Some of the reasons why... and why not.System41. 587–597 (2013), CLIL: Detail matters in the whole picture. More than a reply to J.

Within each one, it counters incorrect data and biased interpretations, updates obsolete information which renders certain arguments invalid, and identifies and provides solutions to the main caveats in the CLIL research hitherto conducted. The ultimate aim is to illustrate how we should neither harbor an excessively optimistic view on the way CLIL is playing out nor maintain an overly dismal outlook on the feasibility of its implementation, and to carve out a future research agenda in order to bring the pendulum to a standstill through solid, unskewed, and unbiased CLIL research.
Wozu dient der Monotheismus in der jüdischen Religion angesichts der Zehnfaltigkeitslehre der Kabbala
Authors: Grözinger Karl E.
Published: June 2016

Judaism is seen as the archetypal monotheistic religion. And yet, the history of the Jewish faith seems to contradict this view: there were other gods besides the God of Israel, later superior angels, Metatron; in speaking of a tenfold deity the Kabbala goes against the philosophical doctrine of oneness to which it also adheres. These seeming contradictions can only be explained if one considers that the various creeds of oneness stem from very different religious and philosophical ways of thinking and concerns, which do not always endeavour to describe God’s existence, but are rooted in a human longing for happiness, the wish to refer to a God, to liturgical accessibility etc. The creed of the one God is ontology for some, for others it is epistemology, liturgical performance, emotional expression or sociological or historical reflection. Monotheism figures in various »linguistic games« and with various meanings.
»… und seinem Köcher Anglis«
Authors: Keil Martha
Published: June 2016

No area of Christian-Jewish co-existence during the medieval Ashkenazi period produced more personal contacts than the business sphere. During loan transactions, Jews and Jewesses interacted with Christian men and women from all social classes, from rulers and nobility to townspeople, farmers, craftsmen, and servants. Therefore, German-Hebrew business contracts are not only material cultural goods in their own right, they also serve as media of cultural transfer and as a shared legal, linguistic, and general cultural zone between Jews and Christians in the field of economics and of business practices. This paper not only deals with legal and linguistic topics, but also with the rather hidden and neglected aspects of polemics and humour.
