Published: June 2016

Το Εργαστήριο Διαπολιτισμικών και Μεταναστευτικών Μελετών του Παιδαγωγικού Τμήματος Δημοτικής Εκπαίδευσης του Πανεπιστημίου Κρήτης υλοποιεί εδώ και δύο χρόνια το Έργο ΕΣΠΑ «Ελληνόγλωσση Πρωτοβάθμια και Δευτεροβάθμια Διαπολιτισμική Εκπαίδευση στη Διασπορά» με ιδιαίτερο στόχο την ανάπτυξη περιβάλλοντος ηλεκτρονικής μάθησης για την ελληνική γλώσσα και στοιχείων ιστορίας και πολιτισμού. Στο άρθρο αυτό παρουσιάζονται η στοχοθεσία και οι βασικοί άξονες υλοποίησης του προγράμματος, αφού πρώτα εκτεθούν οι συνθήκες που χαρακτηρίζουν την ελληνόγλωσση εκπαίδευση στο εξωτερικό.
Μελέτη Μέσων και Σχέσεων Επικοινωνίας στην Εκπαίδευση από Απόσταση με τη χρήση των Κοινωνικών Δικτύων
Authors: Μπαρμπόπουλος Γεώργιος
Published: June 2016

Η εργασία αυτή περιγράφει τα αποτελέσματα μιας μελέτης των τρόπων, με τους οποίους επικοινωνούν μεταξύ τους οι φοιτητές μιας τάξης, δηλαδή, των σχέσεων επικοινωνίας, που διαμορφώνουν στις αλληλεπιδράσεις τους, και των μέσων επικοινωνίας, που χρησιμοποιούν για τις επαφές τους. Πρόκειται για φοιτητές του Ελληνικού Ανοικτού Πανεπιστημίου (Ε.Α.Π.), ίδρυμα το οποίο προσφέρει τη δυνατότητα εξ αποστάσεως σπουδών μέσω υπολογιστών και άλλων μέσων επικοινωνίας, παράλληλα με σύντομες, εντατικές συναντήσεις στους χώρους του. Οι σχέσεις επικοινωνίας μεταξύ αυτών των φοιτητών, που μελετήσαμε, είναι τέσσερις: συνεργασίας, κοινωνικοποίησης, ανταλλαγής τεχνικής βοήθειας και συναισθηματικής στήριξης. Επιπλέον, τα μέσα επικοινωνίας, που θεωρήσαμε ότι χρησιμοποίησαν οι φοιτητές είναι κι αυτά τέσσερα: e-mail, IRC, τηλέφωνο και κατά πρόσωπο (face-to-face) επαφές. Το βασικό μεθοδολογικό εργαλείο της μελέτης μας είναι η θεωρία των κοινωνικών δικτύων, με τη βοήθεια της οποίας προσπαθούμε να αναπαραστήσουμε τα (κοινωνικά) δίκτυα, που συνδέουν μεταξύ-τους τους φοιτητές της τάξης, στις διάφορες χρονικές φάσεις, ως προς τις σχέσεις και τα μέσα επικοινωνίας, που αυτοί αναπτύσσουν και χρησιμοποιούν, αντίστοιχα.
Έτσι, έχουμε βρει ότι για την επικοινωνία των φοιτητών χρησιμοποιήθηκαν, πρωταρχικά, σχεδόν εξολοκλήρου το τηλέφωνο και, σε μικρότερο βαθμό, το ηλεκτρονικό ταχυδρομείο (e-mail). Όμως υπήρχαν ορισμένοι – αλλά λίγοι – φοιτητές, οι οποίοι έκαναν επίσης χρήση των συζητήσεων στο Διαδίκτυο μέσω του IRC. Επιπλέον, η κατά πρόσωπο επικοινωνία, που γινόταν μία φορά το μήνα στο χώρο του Ε.Α.Π., φαίνεται να είχε καταλυτική επίδραση στην ανάπτυξη της κοινωνικοποίησης και της συναισθηματικής στήριξης των φοιτητών. Αναφορικά τώρα με τις σχέσεις επικοινωνίας των φοιτητών, έχουμε βρει ότι οι μελετώμενες τέσσερις σχέσεις παρουσιάζουν μια μάλλον υψηλή ποικιλότητα στις εμφανίσεις τους. Ιδιαίτερα σημαντική, μεταξύ των σχέσεων αυτών, αναδεικνύεται η σχέση της συνεργασίας των φοιτητών έτσι ώστε οι άλλες τρεις σχέσεις (κοινωνικοποίησης, ανταλλαγής τεχνικής βοήθειας και συναισθηματικής στήριξης) να χρειάζεται να οικοδομηθούν πάνω σ’ αυτήν.

Published: June 2016

The aim of our paper is to discuss how the courses of English Language of the Department of Applied and Visual Arts of the School of Fine Arts and of the Departments of Mechanical Engineering, Informatics and Telecommunications Engineering of the School of Engineering of the University of Western Macedonia were taught during the academic year 2014-5 and how students reacted towards the teaching approaches that were adopted. For reasons of economy of space we present here only the experiment that was conducted in the School of Fine arts. These teaching methods we attempted to implement based on bibliographic research, both during the teaching sessions and in the final assessment, were a) translation and b) creative writing. On the one hand, we tried to familiarize students with the meaning and appropriate use of the terminology of their own scientific fields in both the English and the Greek language and on the other hand we attempted to stir their imagination and create an interest in writing. Our aim was to encourage them to produce their own texts by using knowledge from their own scientific field, express their thoughts, feel more confident when communicating in the foreign language and improve their language skills.

 
Foreign languages education in international literary festival tourism: the case of Festivaletteratura in Italy.
Authors: ROSSETTI GIULIA
Published: June 2016

Festivals have always represented a good opportunity on the economic front, but most importantly they have been perfect occasions for creating settings for social, cultural and inter-linguistic interaction. Nowadays, thanks to the globalisation process, intercultural and inter-lingual communications are increasingly important in the festivals domain, especially those focused on international literary events. According to the experiential learning theory, international book festivals can be environments for learning activities, and specifically for language development. Thus, these cultural events have provoked such questions as the following: attending international literary festivals can increase participants' language learning? In what ways do international literary festival managers invest in multilingual services in order to encourage language learning? This study aims to investigate if international literary festivals can develop adult visitors’ language learning, taking Festivaletteratura of Mantua (Italy) as a case study. Firstly, I shall present the importance of interlingual communication in festival tourism and the experiential learnign theory. Secondly, I will explore Festivaletteratura supply analysis, considering also its international projects as potential language training tools: Scritture Giovani and Vocabolario Europeo, and Festivaletteratura’s international connection with other partners: the Hay Festival and the Berlin Internationales Literaturfestival. Then, I will investigate the role of foreign languages in the demand analysis of the festival, according to the questionnaire survey among 300 adult attendees during the 2015 Festivaletteratura edition. Finally, I intend to argue that even if the festival might provide a setting for language learning with lots of international guests, due to its target, who is not familiar with foreign languages, it cannot be described as an example of language learning environment.

Survival strategies for teachers and researchers of ESP in economically challenging times
Authors: WILLIAMS CHRISTOPHER
Published: June 2016

I outline some of the challenges for teachers and researchers of ESP in this period of prolonged economic crisis from the perspective of someone who has taught English for law students and political science students for many years, is editor of the journal ESP Across Cultures, and is Head of the Language Centre of Foggia University. I focus on three issues: 1) teaching LSP at university level in a context of contradictory pressures coming from ministerial insistence on internationalization of Italian universities in an increasingly globalized world while drastically reducing funding at all levels; 2) research in ESP, where I outline the vibrancy of ESP studies despite the economic hardships, but I surmise that this is partly the result of a shift towards providing practical language skills for future professionals in line with the marketization of tertiary education; 3) the emerging role of CLIL (Content and Language Integrated Learning), where in Italy it is now law to provide part of secondary school tuition of a non-language subject in a foreign language: I outline the ways in which ESP and CLIL can mutually complement each other. I conclude by arguing that the future looks bright for ESP studies despite the economic crisis.

 
Oxygen consumption and nutrient fluxes in coastal marine sediments off the Mejerda River delta (Gulf of Tunis)
Authors: HELALI M. A. , ZAABOUB N. , OUESLATI W. , ADDED A. , ALEYA L.
Published: June 2016

The authors studied benthic flux of oxygen, alkalinity, and nutrients in situ at three points in the Mejerda River Delta at depths of 10m, 20m and 40m in March and August 2012. Three sedimentary cores were simultaneously drilled at the same locations to determine the diffusive flux of NO2-, NO3-, NH4+ and PO43- and to estimate diagenetic mechanisms occurring below the sediment-water interface. Photosynthesis was not sufficiently high during the day, and the oxygen consumption at sediment-water interface was about 1.7 to 10mmol/m²/day, essentially controlled by the degradation of organic matter and oxidation of reduced elements. Nitrate contents are relatively high in the sediment (above 140μM for NO3-)and their production is not always in conformity with the general scheme of early diagenesis, moreover, benthic flux between water and sediment are not clearly established. The diffusive flux of NH4+ and PO43- are always directed to the water column, at averages of 1.27μmol/m²/day for PO43- and 96.5μmol/m²/day for NH4+, complying with those measured by benthic chambers, but representing less than 30% of benthic fluxes for NH4+ and less than 5% for PO43-.
The use of Depletion Methods to assess Mediterranean cephalopod stocks under the current EU Data Collection Framework

Published: June 2016

Fuelled by the raising importance of cephalopod fisheries in Europe, there have been demands from scientists and stakeholders for their assessment and management. However, little has been done to improve the data collection in order to analyse cephalopod populations under the EU Data Collection Framework (DCF). While the DCF allows member states to design flexible national sampling programmes, it establishes the minimum data requirements (MDR) each state is obliged to fulfil. In this study, it was investigated whether such MDR currently set by the DCF allow the application of depletion models (DMs) to assess European cephalopod stocks. Squid and cuttlefish fisheries from the western Mediterranean were used as a case study. This exercise sheds doubt on the suitability of the MDR to properly assess and manage cephalopod stocks by means of DMs. Owing to the high plasticity of life-history traits in cephalopod populations, biological parameters should be estimated during the actual depletion period of the fished stocks, in contrast with the triennial sampling established by the DCF. In order to accurately track the depletion event, the rapid growth rates of cephalopods implies that their populations should be monitored at shorter time scales (ideally weekly or biweekly) instead of quarterly as required by the DCF. These measures would not demand additional resources of the ongoing DCF, but a redistribution of sampling efforts during the depletion period. Such changes in the sampling scheme could be designed and undertaken by the member states or directly integrated as requirements.
Tracking the invasion of Hemiramphus far and Saurida undosquamis along the southern Mediterranean coasts: A Local Ecological Knowledge study

Published: June 2016

Local Ecological Knowledge of 92 professional fishers from Tunisia and Libya was used to investigate on the occurrence and establishment of the exotic Hemiramphus far and Saurida undosquamis along the southern Mediterranean coasts. According to fisherman’s knowledge, H. far and S. undosquamis appeared in Libya, in 1980 and 1989 respectively. In Tunisia these species were observed afterwards, in 2004 and 2007. Currently both H. far and S. undosquamis result to be well distributed and established, along the entire surveyed area, from Tubrouk (eastern Libya) to Tabarka (western Tunisia). A statistical analysis of the qualitative trends in abundance perceived by the respondents show that both species have significantly increased in abundance in Tunisia. In Libya an increase of the abundance of H. far was also apparent during the first decade of the 21st century but the current abundance of S. undosquamis resulted to be stable at the level of occasional captures. Given the lack of regular environmental monitoring programmes in the area, these findings provide information that could not have been obtained otherwise. Besides improving our understanding on the status and chronology of these invasions, this approach highlights the value of fisherman’s knowledge to reconstruct ecological process in the course of rapid historical modifications.
Seasonal and Interannual Variability of Water Exchange in the Strait of Istanbul
Authors: ALTIOK Η. , KAYIŞOĞLU M.
Published: June 2016

Temperature and salinity distribution and volume fluxes through the Strait of Istanbul were analysed using long-term monthly time series of temperature-salinity (1996-2010) and current profiles (1999-2010) collected at both ends of the strait. While annual cycle of the upper layer temperature, with minima in February and maxima in August, reflects the influence of air temperature with a near monthly phase shift, annual cycle of the upper layer salinity, with lowest values observed between April to September, is mostly affected by river discharge into the Western Black Sea. The seasonal variations of the lower layer temperature and salinity in the Strait of Istanbul are mostly influenced by flow blockages. Inversely proportional upper and lower layer volume fluxes indicate strong seasonal variations with minimum and maximum values in April and October, respectively. Annual average upper and lower layer volume fluxes calculated from the high resolution dataset are 404 km3 y-1 and 250 km3 y-1 at the north end, and 430 km3 y-1 and 245 km3 y-1 at the south end of the strait, respectively.

Published: June 2016

Human activities are increasingly impacting biodiversity. To improve conservation planning measures in an ecosystem-based management context, we need to explore how the effects of these activities interact with different biodiversity components. In this study, we used a semi-quantitative method to assess the cumulative impacts of human activities on three biodiversity components (species richness, phylogenetic diversity, and functional diversity) in Tunisia’s exclusive economic zone. For each of the nine activities considered, we developed an understanding of their effects from local studies and the expert opinion of stakeholders with country-specific experience. We mapped the cumulative effects and the three biodiversity components and then assessed the degree to which these elements overlapped using an overlap index. This is the first time such an assessment has been made for Tunisia’s marine ecosystems and our assessment highlight the inappropriateness of current conservation measures. The results of this study have specific application for the prioritization of future management actions.
Morphological and genetic barcoding study confirming the first Stegastes variabilis (Castelnau, 1855) report in the Mediterranean Sea
Authors: VELLA A. , AGIUS DARMANIN S. , VELLA N.
Published: June 2016

This paper presents morphometric and genetic barcoding analyses of the first record of the Cocoa Damselfish, Stegastes variabilis in the Mediterranean Sea. A single specimen was captured from Senglea waterfront, Malta (Central Mediterranean) on the 15th of September 2013. The species is non-indigenous in the Mediterranean, as it is native to the tropical Western Atlantic. Apart from undertaking identification through meristics and morphometric measurements of the specimen, genetic analyss of the 3410 bp mtDNA genes were carried out to confirm the species' identity. The latter was useful given that the genus Stegastes is known to be composed of morphologically very similar species, with variable colour patterns.
Illegal immigration in the eastern Aegean Sea: a new source of marine litter
Authors: KATSANEVAKIS S.
Published: June 2016

The maritime area dominates the current increasing wave of illegal immigration to Europe. The Greek islands of the eastern Aegean Sea are the main entrance points of immigrants arriving from the coasts of Turkey. Immigration to the Greek islands is mainly conducted with inflatable boats, which are abandoned upon arrival along the coasts together with other items such as life-jackets, inflatable tubes, and clothing. This novel type of marine litter dominates many beaches and becomes increasingly abundant. Two beaches in Lesvos Island were surveyed for marine litter, and immigration-related items were found to account for more than 97% of marine litter by weight. Immigration-related littering adds pressure on marine biodiversity and the local economy, impacting the recreational value of beaches.
FEEDING HABITS AND HELMINTH PARASITES OF SARDINE (S. PILCHARDUS) AND ANCHOVY (E. ENCRASICOLUS) IN THE ADRIATIC SEA

Published: June 2016

We examined the stomach contents of two of the most economically and ecologically important small pelagic fish species, the sardine, Sardina pilchardus and the anchovy, Engraulis encrasicolus, obtained monthly from commercial purse-seine catches operating on Croatian fishing grounds during a one-year period (January–December, 2011). Both species generally showed a similar diet, with copepod and decapod larvae as dominant prey groups. The composition of anchovy and sardine stomach contents was not size- or sex-related, but throughout the year, a significant difference in diet composition was observed for each species as well as between species. Two gastrointerstinal helminths; the digenean Parahemiurus merus and nematode Hysterothylacium aduncum, were recorded during the stomach content analysis. Differences in population dynamics between the two parasites are congruent with differences in the prey composition of sardine and anchovy, reflecting fine-tuned interactions in the trophic web between parasites and intermediate or paratenic hosts included in the sardine and anchovy diet.
Ecosystem dynamics in the Liguro-Provençal Basin: the role of eddies in the biological production.

Published: June 2016

We study numerically the role of mesoscale structures in the Ligurian Sea (NW Mediterranean Sea) as a possible factor affecting the spatial distribution of the chlorophyll spring bloom. We use the Regional Ocean Modeling System (ROMS) configured for the NW Mediterranean Sea (ROMS_NWMed) and satellite derived Altimetric, Sea Surface Temperature and Chlorophyll concentration data, for years 2009 and 2010. Comparison of model output with satellite and in situ data shows agreement between numerical results and observations. There is a significant interannual variability in concentration and distribution of chlorophyll in the basin during the two years of the study. The ROMS_NWMed simulation reveals the formation of a number of mesoscale eddies along the Northern rim Current characterized by a long lifetime and closed streamlines. A significant higher number of eddies is found during the chlorophyll-rich year 2010. The high number of eddies, due to the “eddy pumping mechanism”, generate spatially and temporally localised fluxes of nutrient into the euphotic zone, thus contributing to the fertilization of the Ligurian Sea. Therefore, eddies in the Ligurian rim current can have important effects on the location of development of the main patch of chlorophyll spring bloom and consequently on the local ecosystem dynamics.

Benthic communities were studied twice (autumn and spring) in three Mediterranean coastal lagoons located in Greece (Logarou) and Italy (Cesine and Grado-Marano). The species composition and distribution, the community diversity, the species richness, the dominant taxa and their ecological identity, the benthic trophic and biomass size structure were investigated in these lagoons and the the results were correlated with environmental variables.The overall similarity based on species composition and abundance among lagoons was low due to differences in dominant environmental factors, whereas variations of community diversity and species richness were mainly related to the degree of marine influence, reflecting the natural structure. The benthic classification indices AMBI, M-AMBI, BENTIX, BO2A, ISD and ISS were applied to assess the ecological status of the lagoons studied. Results showed that the biotic indices AMBI, M-AMBI, BENTIX, and BO2A are not adequately efficient due to the natural dominance of tolerant and opportunistic species and the correlation of species diversity to natural stress. ISD and ISS on the other hand, based on size distribution frequencies and on size spectra sensitivity respectively, had a good discrimination power between impacted and unimpacted sites. Results indicate that alternatively to the species sensitivity, other traits of the communities as the biomass or size structure could be more robust, sensitive and effective in assessing the ecological quality in lagoons.
Settlement pattern of Posidonia oceanica epibionts along a gradient of ocean acidification: an approach with mimics

Published: June 2016

Effects of ocean acidification (OA on the colonization/settlement pattern of the epibiont community of the leaves and rhizomesof the Mediterranean seagrass,Posidoniaoceanica, have been studied at volcanic CO2vents off Ischia (Italy), using “mimics”as artificial substrates. The experiments were conducted in shallowPosidoniastands (2-3 m depth), in three stations on the northand three on the south sides of the study area, distributed along a pH gradient. At each station, 4 rhizome mimics and 6 artificialleaves were collected every three months (Sept 2009-Sept 2010). The epibionts on both leaf and rhizome mimics showed clearchanges along the pH gradient; coralline algae and calcareous invertebrates (bryozoans, serpulid polychaetes and barnacles) weredominant at control stations but progressively disappeared at the most acidified stations. In these extremely low pH sites theassemblage was dominated by filamentous algae and non calcareous taxa such as hydroids and tunicates. Settlement pattern onthe artificial leaves and rhizome mimics over time showed a consistent distribution pattern along the pH gradient and highlightedthe peak of recruitment of the various organisms in different periods according to their life history.Posidoniamimics at theacidified station showed a poor and very simplified assemblage where calcifying epibionts seemed less competitive for space. Thisprofound difference in epiphyte communities in low pH conditions suggests cascading effects on the food web of the meadow and,consequently, on the functioning of the system
First record of Calma gobioophaga Calado and Urgorri, 2002 (Gastropoda: Nudibranchia) in the Mediterranean Sea

Published: June 2016

Specimens of the nudibranch genus Calma were observed under stones at two Croatian localities while feeding on gobiid eggs. Some ambiguous morphological features compared with the original descriptions of the known species of the genus, C. glaucoides and C. gobioophaga, hampered an easy identification. Genetic data (COI and 16S sequences) confirmed the distinction between the two species of the genus Calma, and allowed to unambiguously identify the Croatian specimens as Calma gobioophaga. This is the first record of this species for the Mediterranean and extends remarkably its distribution range. Finally, the eggs fed by the Croatian specimens have been taxonomically identified by using the 12S rDNA marker as Gobius cobitis.
Concern about the spread of the invader seaweed Caulerpa taxifolia var. distichophylla (Chlorophyta: Caulerpales) towards the West Mediterranean

Published: June 2016

The new Australian alien seaweed Caulerpa taxifolia var. distichophylla, after being established along the Turkish Mediterranean coast in 2006, was recorded in Southern Sicily in 2007. Since then local fishermen claimed support to counteract the effects of entanglement of large amounts of the alien strain wrack in their trammel nets, causing the gear to become ineffective. The further northward and westward spread of the new alien strain is supposed to be limited by winter temperature. We present novel data confirming that the new alien strain is fully naturalized in Central Mediterranean and is expanding its range beyond such limit (i.e. the 15°C February isotherm), thus becoming potentially able to colonize the western basin. By means of a preliminary estimation of effects on native polychaete assemblages, and considering some peculiarities of Sicily (mostly linked to its geographical position in the Mediterranean Sea), the risk linked to the increasing range of distribution of the invasive algae is highlighted.

The Mediterranean basin is recognized as one of the most diverse regions on the planet, but is being threatened by overexploitation and habitat loss. Furthermore, the Strait of Gibraltar and adjacent Alboran Sea have been identified as representing an important habitat for many threatened or endangered species. In this context, one vehicle for marine conservation is the creation of marine protected sites, although Mediterranean Marine Protected Areas (MPAs) are neither large nor representative enough to form an effective network of protection. An inventory of the benthic communities and habitats of conservation interest has been carried out in Cap des Trois Fourches, an ecological and biogeographical site of interest. Univariate and multivariate analyses showed differences for marine communities among habitats and localities, indicating a great diversity in marine assemblages but an absence of a spatial gradient in marine α-diversity. The Trois Fourches area showed a high environmental quality and hosted several endangered species. Habitats of conservation concern, such as marine caves, seagrass meadows and coralligenous assemblages, were detected and studied. The scientific data recorded provide sound support for the establishment of a new MPA in Trois Fourches, taking into account that the findings match the scientific criteria required for declaration as a protected area. The benefits for connectivity at the Mediterranean scale and the local economy are discussed.
The non-indigenous Paranthura japonica Richardson, 1909 in the Mediterranean Sea: travelling with shellfish?

Published: June 2016

An anthurid isopod new to the Mediterranean Sea has recently been observed in samples from three localities of the Italian coast: the Lagoon of Venice (North Adriatic Sea), La Spezia (Ligurian Sea) and Olbia (Sardinia, Tyrrhenian Sea). The specimens collected showed strong affinity to a species originally described from the NW Pacific Ocean: Paranthura japonica Richardson, 1909. The comparison with specimens collected from the Bay of Arcachon (Atlantic coast of France), where P. japonica had been recently reported as non-indigenous, confirmed the identity of the species. This paper reports the most relevant morphological details of the Italian specimens, data on the current distribution of the species and a discussion on the pathways responsible for its introduction. The available data suggest that the presence of this Pacific isopod in several regions of coastal Europe might be due to a series of aquaculture-mediated introduction events that occurred during the last decades of the 1900s. Since then, established populations of P. japonica, probably misidentified, remained unnoticed for a long time.

Published: June 2016

The spatial distribution of Pinna nobilis densities have been analysed through a geostatistical approach in the MPA of Cabrera National Park, Balearic Islands (Spain), Western Mediterranean Sea. Regression kriging was used to model the effect of environmental variables on the density of living individuals of P. nobilis and generate a predictive map of its distribution within the MPA. The environmental variables considered for the model were: depth; slope; habitat type and heterogeneity; wave exposure; and MPA zoning. A total of 378 transects were randomly distributed with a total of 149,000 m2 surveyed at a depth range from 4.2 to 46 m. The recorded P. nobilis densities are among the highest in the Mediterranean Sea. With respect to the prediction model, results indicate that benthic habitats play a key role in the spatial distribution of P. nobilis, with higher densities in seagrass meadows of Posidonia oceanica. The fan mussel population density peaked at 9 m depth, decreasing with depth. Also, decreasing densities are expected with increasing exposure to waves. The predicted map shows some hotspots of density different in size and distributed along the MPA, and provides valuable information for the spatial conservation management of this species.

ANALYSIS OF DAMAGED TURBINE BLADES OF THE ENGINE MPM 20
Authors: Čerňan Jozef , Hocko Marián , Cúttová Miroslava , Semrád Karol
Published: June 2016

The objects of the investigation are damaged gas turbine blades of the MPM – 20 jet engine as a result of exceeding the temperature of the hot gases at the entrance of the gas turbine. On the damaged turbine blade metallographic-microscopic analysis was performed to identify aspects and consequences that accompanied the fracture. The research results showed phase changes in the structure as well as a significant oxidation along the grain boundaries, where cracks, leading to the destruction of the tip, were initiated. Toward the damage of the blades significantly contributed also the fact that higher temperatures cause higher thermal expansion and thus there was a clash of blades with an outer turbine casing. The subsequent mechanical deformation resulted in places of oxidized grains to cracking and a gradual detaching of the blade material in the form of partial fractures.
Revisiting the Small-Firm Effect on Entrepreneurship: Evidence from Firm Dissolutions
Authors: Kacperczyk Aleksandra , Marx Matt
Published: June 2016

Afrequent claim in the entrepreneurship literature is that employees learn to become entrepreneurs during paid employment. We revisit this mechanism in the context of the well-established finding that smaller firms generate higher rates of entrepreneurship. We propose a novel mechanism responsible for higher rates of entrepreneurship emanating from smaller firms: large firms might have a advantage over small firms in providing internal opportunities to retain entrepreneurial talent. We test this claim in a setting where firm dissolution extinguishes internal opportunities, using a new hand-collected data set of career histories in the automatic speech recognition (ASR) industry. For nondefunct firms, we replicate the “small-firm effect.” However, the small-firm effect no longer holds within the subsample of defunct firms: entrepreneurship rates among individuals present at firm dissolution are in fact higher for larger firms. Additional analyses indicate that this effect is unlikely to be driven by the early departure of higher-skilled workers who anticipate the firm’s demise. Finally, we find preliminary evidence consistent with the notion that large organizations may not only retain but also “mold” workers into entrepreneurs. More broadly, the study emphasizes the need to consider a novel mechanism responsible for transition into entrepreneurship—the role of opportunities available to employees in incumbent firms.

Vermicomposts have higher level of available nutrients like carbon nitrogen, phosphorous and potassium, calcium and magnesium derived from the wastes. The paper has attempted to evaluate for development of efficacy vermicompost by using three varieties of earthworms. The use of earthworms in the degradation of different types of wastes is continuing from the past so many years. These wastes include industrial, agricultural of plant debris and domestic waste papers and cattle dung. In this study three varieties of earthworms used such as Eisenia fetida, Eudrilus eugeniae and Perionyx excavates in the vermicomposting of plant debris, cattle dung and waste paper. As waste paper, cattle dung and plant debris are rich in carbon while deficient in nitrogen cow dung was mixed with it to make it suitable for three earthworms. A mixture of waste paper, plant debris and c dung in the ratio of 1:1:1 was found to be the best ratio than 3(paper waste): 2(cattle dung) and 5(plant debris). In 60 days time excellent quality and quantity of compost was produced by three earthworms. Physical and biochemical parameters were analyzed during this period of 60 days. Pre decomposition of 10 days and subsequent vermicomposting of 60 days indicates the role of this species in vermibiotechnology. Increase was found in all the parameters like, Total nitrogen (%), Available phosphorus (%) and Exchangeable potassium (%) while a decrease was found in pH and C:N ratio as the timing of vermicomposting increased from 0 days to 60 days.
Performance of Livestock Sector in India (With Reference to Bovine Population)
Authors: Reddy B , Ramappa P
Published: June 2016

Most of the farmers in India depend on agriculture and allied activities. The dairying has been playing a major role by providing livelihoods to the rural people. The objectives of the study are: to know the growth in the bovine population in India, analyse the trends in milk production and per capita availability of milk and analyse the share of livestock production in GDP. The study reveals that the percentage share of cows declined and that of buffaloes significantly increased. It is due to high price for buffalo milk. It is observed that the percentage of CB cattle in total cattle increased and that of indigenous cattle population declined. The per capita availability of milk increased from 130 grams per day in 1950 to 299 grams in 2012. The share of livestock sector in agriculture GDP also increased from 13.88% in 1980-81 to 29.20% in 2012-13. Among the top ten countries in the world India is in 2nd position in cow milk production. It is also evident that among the top ten countries India is in 1st position in buffalo milk production. It is observed that the milk yield per head is low in India. Hence there is need to raise the milk yield in order to enhance the per capita availability of milk and to meet the increasing demand. Measures must also be taken to protect the cattle and to increase their number.
Impact of marine mercury cycling on coastal atmospheric mercury concentrations in the North- and Baltic Sea region
Authors: Bieser Johannes , Schrum Corinna
Published: June 2016

The cycling of mercury between ocean and atmosphere is an important part of the global Hg cycle. Here we study the regional contribution of the air-sea exchange in the North- and Baltic Sea region. We use a newly developed coupled regional chemistry transport modeling (CTM) system to determine the flux between atmosphere and ocean based on the meteorological model COSMO-CLM, the ocean-ecosystem model ECOSMO, the atmospheric CTM CMAQ and a newly developed module for mercury partitioning and speciation in the ocean (MECOSMO). The model was evaluated using atmospheric observations of gaseous elemental mercury (GEM), surface concentrations of dissolved gaseous mercury (DGM), and air-sea flux (ASF) calculations based on observations made on seven cruises in the western and central Baltic Sea and three cruises in the North Sea performed between 1991 and 2006. It was shown that the model is in good agreement with observations: DGM (Normalized Mean Bias NMB=-0.27 N=413), ASF (NMB=-0.32, N=413), GEM (NMB=0.07, N=2359). Generally, the model was able to reproduce the seasonal DGM cycle with the best agreement during winter and autumn (NMBWinter=-0.26, NMBSpring=-0.41, NMBSummer=-0.29, NMBAutumn=-0.03). The modelled mercury evasion from the Baltic Sea ranged from 3400 to 4000 kg/a for the simulation period 1994–2007 which is on the lower end of previous estimates. Modelled atmospheric deposition, river inflow and air-sea exchange lead to an annual net Hg accumulation in the Baltic Sea of 500 to 1000 kg/a. For the North Sea the model calculates an annual mercury flux into the atmosphere between 5700 and 6000 kg/a.

The mercury flux from the ocean influenced coastal atmospheric mercury concentrations. Running CMAQ coupled with the ocean model lead to better agreement with GEM observations. Directly at the coast GEM concentrations could be increased by up to 10% on annual average and observed peaks could be reproduced much better. At stations 100km downwind the impact was still observable but reduced to 1–3%.

Published: June 2016

Objectives

Despite the fact that research fraud and misconduct are under scrutiny in the field of orthopaedic research, little systematic work has been done to uncover and characterise the underlying reasons for academic retractions in this field. The purpose of this study was to determine the rate of retractions and identify the reasons for retracted publications in the orthopaedic literature.

Methods

Two reviewers independently searched MEDLINE, EMBASE, and the Cochrane Library (1995 to current) using MeSH keyword headings and the ‘retracted’ filter. We also searched an independent website that reports and archives retracted scientific publications ( www.retractionwatch.com ). Two reviewers independently extracted data including reason for retraction, study type, journal impact factor, and country of origin.

Results

One hundred and ten retracted studies were included for data extraction. The retracted studies were published in journals with impact factors ranging from 0.000 (discontinued journals) to 13.262. In the 20-year search window, only 25 papers were retracted in the first ten years, with the remaining 85 papers retracted in the most recent decade. The most common reasons for retraction were fraudulent data (29), plagiarism (25) and duplicate publication (20). Retracted articles have been cited up to 165 times (median 6; interquartile range 2 to 19).

Conclusion

The rate of retractions in the orthopaedic literature is increasing, with the majority of retractions attributed to academic misconduct and fraud. Orthopaedic retractions originate from numerous journals and countries, indicating that misconduct issues are widespread. The results of this study highlight the need to address academic integrity when training the next generation of orthopaedic investigators. Cite this article: J. Yan, A. MacDonald, L-P. Baisi, N.

Biodiversitas 17: 515-522. The biomass of fishes was estimate in the Shadegan Wetland with Leslie model. Also the relationships between fish biomass and physic-chemical parameters of were studies. Sampling was carried out seasonally at five stations; include Atish, Khorosy, Mahshar, Rogbe, and Salmane from April 2013 to March 2014. During this study, 2795 specimens were measured and weighed. The highest fish biomass and lowest fish biomass were in springand winter seasons and Khorosy and Rogbe stations have highest and lowest fish biomass. The mean biomass of fish in four seasons Shadegan, 243Â±35 (kg/ha) and the amount of biomass in different seasons were not significantly different (P>0.05). Average values of water physicochemical parameters in different seasons were no significant (P>0.05), however average values of salinity stations were significant differences (P<0.05). Fish biomass regressions was estimated as Fish Biomass = 0.41 (temperature) 2.56. CCA ordination explained temperature, salinity, PH and DO, as the most important variables influencing the variation of fish composition in the Shadegan Wetland. Multi-layer artificial neural network showed four parameters (temperature, salinity, depth and DO) have the greatest impact on fish biomass.

Published: June 2016

BACKGROUND

The quantification of genomic chimerism is increasingly recognized for its clinical significance after transplantation. Before the measurement of chimerism, accurate genotyping of genetic polymorphisms for informative alleles that can distinguish donor DNA from recipient DNA is essential. The ease of allelic discrimination of small deletion and insertion polymorphisms (DIPs) makes DIPs attractive markers to track chimerism. Current methodologies for the genotyping of DIPs are largely based on “open-tube” approaches. “Closed-tube” approaches involving no or minimal post-PCR handling are preferred. We compared 3 distinct methodologies to determine an optimal platform for DIP genotyping.

METHODS

Genomic DNA from 19 normal individuals was genotyped for 6 small biallelic DIPs using high-resolution melting analysis (HRMA), probe-free droplet digital PCR (ddPCR), and microfluidic electrophoresis of PCR products. For HRMA, 3 different platforms were compared.

RESULTS

Our newly developed probe-free ddPCR approach allowed the genotype of each DIP to be determined by fluorescence intensity based on amplicon size. Microfluidic electrophoresis also allowed genotypes to be determined by amplicon size. HRMA assays allowed the genotype of each DIP to be determined by melting profile. Genotyping results were concordant between the 3 methodologies. HRMA was the most readily performed methodology and was robust across 3 separate HRMA-capable platforms.

CONCLUSIONS

We demonstrated the effectiveness of probe-free ddPCR to accurately genotype small biallelic DIPs. Nevertheless, HRMA proved to be the optimal approach for genotyping small DIPs because closed-tube approaches are preferred owing to rapid and less laborious workflows and least risk of PCR contamination.
Endogenous timing in a vertically differentiated mixed duopoly with Cournot competition
Authors: Feng Leidong , Gu Mengdi
Published: June 2016

This paper compares the equilibrium outcomes under simultaneous and sequential output setting in a mixed duopoly in a vertically differentiated market. When the timing of the output game is determined endogenously, it is shown that simultaneous play in the quality stage with the public firm acting as the high-quality producer and simultaneous play in the second period in the output stage turn out to be the unique subgame perfect Nash equilibrium, which contrasts with the endogenous timing in a purely private duopoly.
