Published: May 2013

The common octopus Octopus vulgarisCuvier, 1797 is the most fished cephalopod species along the Spanish coasts. Its catches are highly fluctuating due to the short life cycle of the species and to the annual variability of the recruitment pattern, strongly dependent on the environmental conditions affecting the eggs and paralarvae. This study examines the common octopus fishery, the catch composition, and the main features of the reproductive biology of this species in the Gulf of Alicante (Spanish Eastern coast, Western Mediterranean FAO division 37.1.1). The common octopus fishery was studied analysing the monthly landing and effort data by fishing gear from 1994 to 2005. Monthly samplings of the commercial O. vulgarislandings from trawlers and clay pots from January 2004 to December 2005 resulted in the measuring of 1833 specimens to enable analysis of the catch composition, and allowed the biological sampling of 1176 individuals to provide the reproductive parameters of the species in the study area. The length-weight relationship calculated for the species was BW = 0.51 * DML 2.87. The yearly sex ratios (males:females) were 1:1 (trawl, 2004), 1:0.74 (trawl, 2005), and 1:0.88 (clay pots, 2005). The size (dorsal mantle length, DML) at maturity of the species in the study area was 9.67 cm for males and 14.38 cm for females. The gonadosomatic index reached a peak between April and July for males and in July for females. The Fulton condition index was lower in both sexes between June and September, and for males in November-December, whereas for both sexes the values of the digestive gland index were at their maximum between June and December. The energy allocation between somatic and reproductive growth was investigated and the results suggested that the energy spent on reproduction mainly came from feeding, and not from energy stored in the mantle tissues or in the digestive gland
Storm surges in the Western Black Sea. Operational forecasting
Authors: MUNGOV G. , DANIEL P.
Published: May 2013

The frequency of the storm surges in the Black Sea is lower than that in other regions of the World Ocean but they cause significant damages as the magnitude of the sea level set-up is up to 7-8 times greater than that of other sea level variations. New methods and systems for storm surge forecasting and studying their statistical characteristics are absolutely necessary for the purposes of the coastal zone management. The operational forecasting storm surge model of Meteo-France was adopted for the Black Sea in accordance with the bilateral agreement between Meteo-France and NINMH. The model was verified using tide-gauge observations for the strongest storms observed along the Bulgarian coast over the last 10 years.
Recent findings of Ommastrephes bartramii (Cephalopoda: Ommastrephidae) in the eastern Mediterranean and the implication on its range expansion

Published: May 2013

The neon flying squid Ommastrephes bartramii is found circumglobally in subtropical, temperate waters and sustains important fisheries in the North Pacific, but it is rarely encountered in the Mediterranean Sea. During the last decade, and particularly since 2004, the frequency of its presence in the Aegean Sea and nearby regions has increased, raising a question about a change in the species distribution and abundance in this area. In this study, we reviewed the literature on O. bartramii findings in the Mediterranean Sea and present new data describing body and beak morphometry, diet and the maturity of specimens recently collected from the easternmost basins. According to data from the entire Mediterranean Sea, collected individuals reached 66 cm in mantle length (ML), wherein only females were larger than 32 cm in ML. An isometric growth in body weight (BW) was shown, whereas the lower beak rostral length (LRL) was allometrically positive in relation to the ML. Occasional catches by jigs during experimental cruises provided most of the individuals recorded in the period from 1982-1992. In contrast, the most recent records are primarily comprised of mature females collected on or near the shore in the eastern basin and of predominantly smaller individuals from the western basin caught by professional jigging fisheries. The distribution of the specimen recorded from the Aegean Sea indicates an association between the species distribution and the circulation of the warm Levantine Intermediate Water. The more frequent observations of moribund spawning females at the periphery of the Cretan Sea are indicative of a spawning ground at this area. The suspected recent increase of O. bartramii abundance in both the northeastern and northwestern basins might be due to the warming of upper sea layers, which has been observed since the mid-1980s and is considered to be the main factor driving the northward expansion of the warm-water species’ range within the Mediterranean Sea.
First occurrence of a Hymenosomatid crab Elamena mathoei (Desmarest, 1823) (Crustacea: Decapoda: Brachyura) in the Mediterranean Sea

Mediterranean fauna is undergoing drastic modifications as a result of anthropogenic activities and global warming. The most important of these is the colonization of the Mediterranean Sea by alien species, many of them entering through the Suez Canal. While many of them are still confined to the Levant Basin, several have extended their distribution westwards to Tunisian waters. The presence of the Indo-west Pacific hymenosomatid crab Elamena mathoei on a rocky shore at Sidi Daoud, Cape Bon Peninsula, Tunisia, is the first Mediterranean record of this species. It is a testimony to the changes in the patterns of invasion in the Mediterranean Sea.
Development of sexual organs and fecundity in Octopus vulgaris Cuvier, 1797 from the Sardinian waters (Mediterranean Sea)

Published: May 2013

In this paper we report information about the sexual maturity process of 245 Octopus vulgaris specimens (75 females and 170 males) from the Mediterranean Sea. For both sexes, six stages of sexual maturity (immature, developing, maturing, mature, spawning, and spent) are identified on the basis of macroscopic and microscopic observations of the reproductive system and linked with some reproductive indices. A good correspondence between gonad appearance and its histological structure is observed, highlighting, in females, how oviducal gland morphology plays a crucial role in the macroscopic evaluation of maturity. The Gonadosomatic and Hayashi indices, in the two genders, and the Oviducal Gland index in females alone do not allow distinguishing all the stages in an irrefutable way. Data on the potential fecundity, oocyte and spermatophore size are reported and compared with literature. In addition, spermatophore components are also computed. The results reported in this paper lead to easy identification of the different phases of sexual maturation of O. vulgaris and could constitute an important tool for defining assessment models in view of sound management of this species.
Records of Polydora cornuta and Streblospio gynobranchiata (Annelida, Spionidae) from the Black Sea
Authors: RADASHEVSKY V.I. , SELIFONOVA Z.P.
Published: May 2013

Two spionid polychaetes, Polydora cornuta and Streblospio gynobranchiata, were identified in benthic samples collected in the northern Black Sea and adjacent waters. These species have earlier been classified as the worst invaders in soft bottom communities in the Mediterranean Sea. Polydora cornuta had been previously misidentified and widely reported from the Black Sea and the Sea of Azov as P. ciliata, P. ciliata limicola and P. limicola. Streblospio gynobranchiata is a new invader currently extending its distribution into the Mediterranean, Black and Caspian Seas. Morphology, diagnostic characters and biology of the species are discussed and the history of their records in the Mediterranean, Black and Caspian Seas and the Sea of Azov is reviewed.
"Protected" marine shelled molluscs: thriving in Greek seafood restaurants

International agreements as well as European and national legislation prohibit exploitation and trading of a number of edible marine shelled molluscs, due to either significant declines in their populations or destructive fishing practices. However, enforcement of existing legislation in Greece is ineffective and many populations of “protected” species continue to decline, mainly due to poaching. The extent of illegal trading of protected bivalves and gastropods in Greek seafood restaurants was investigated by interviewing owners or managers of 219 such restaurants in 92 localities. Interviews were based on questionnaires regarding the frequency of availability in the menus and the origin of twenty-one species or groups of species, among which eight are protected - illegally exploited. Forty-two percent of the surveyed restaurants were found to serve at least one of the protected ¬- illegally exploited species. Among the illegally traded species, Lithophaga lithophaga, Pecten jacobaeus, and Pinnanobilis were served in a relatively high proportion of the surveyed restaurants (22.8%, 19.2%, and 16.4% respectively), outrunning many commercial species. In many cases these species were always or often available (11.4%, 4.6% and 5.0% respectively). There was substantial spatial variation in the proportion of restaurants that illegally served protected species with differing patterns for each species; very high proportions of illegal trading were observed in some marine regions (e.g., date mussels were served in >65% of the seafood restaurants along the coastline of Evvoikos Gulf). In most cases the illegally traded species were of local origin, while there was no finding of illegally imported molluscs from other countries. The strategy for enforcement of existing legislation should be greatly improved otherwise protection of shelled molluscs will remain ineffective.
Temperature and salinity variability in the Greek Seas based on POSEIDON stations time series: preliminary results

Published: May 2013

Temperature and salinity time series provided by three POSEIDON monitoring stations (buoys) are examined in order to study the seasonal and interannual variability of the water mass characteristics. The sites at Athos (North Aegean Sea), E1M3A (Central Cretan Sea) and Pylos (Eastern Ionian Sea) were chosen, as these buoys provide measurements at various depths, while they represent 3 major basins respectively. The study of the T and S characteristics reveals important seasonal changes and highlights the particular characteristics of each basin. Dense water production in the Northern Aegean is found to be hindered by the presence of the surface Black Sea Water (BSW) mass. On the other hand, the intermediate water mass in the Cretan Sea is shown to be ventilated during the winter season. A significant temperature and salinity increase has been monitored over both the Central Cretan and Eastern Ionian Seas starting from the middle of 2008 and 2009 respectively. This could possibly be attributed to changes in the intermediate water masses of the Eastern Mediterranean, without ruling out the possibility of water mass exchanges between the two basins.
First record of Pontian Monkey Goby, Neogobius fluviatilis (Pallas, 1814) in the Evros River (Greece); Is it an alien species?
Authors: ZOGARIS S. , APOSTOLOU A.
Published: May 2013

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.

The state-of-art on alien species in the Mediterranean Sea is presented, making distinctions among the four subregions defined in the EU Marine Strategy Framework Directive: (i) the Western Mediterranean Sea (WMED); (ii) the Central Mediterranean Sea (CMED); (iii) the Adriatic Sea (ADRIA); and (iv) the Eastern Mediterranean Sea (EMED). The updated checklist (December 2010) of marine alien species within each subregion, along with their acclimatization status and origin, is provided. A total of 955 alien species is known in the Mediterranean, the vast majority of them having being introduced in the EMED (718), less in the WMED (328) and CMED (267) and least in the Adriatic (171). Of these, 535 species (56%) are established in at least one area.Despite the collective effort of experts who attempted in this work, the number of introduced species remains probably underestimated. Excluding microalgae, for which knowledge is still insufficient, aliens have increased the total species richness of the Mediterranean Sea by 5.9%. This figure should not be directly read as an indication of higher biodiversity, as spreading of so many aliens within the basin is possibly causing biotic homogenization. Thermophilic species, i.e. Indo-Pacific, Indian Ocean, Red Sea, Tropical Atlantic, Tropical Pacific, and circum(sub)tropical, account for 88.4% of the introduced species in the EMED, 72.8% in the CMED, 59.3% in the WMED and 56.1% in the Adriatic. Cold water species, i.e. circumboreal, N Atlantic, and N Pacific, make up a small percentage of the introduced species, ranging between 4.2% and 21.6% and being more numerous in the Adriatic and less so in the EMED.Species that are classified as invasive or potentially invasive are 134 in the whole of the Mediterranean: 108 are present in the EMED, 76 in the CMED, 53 in the Adriatic and 64 in the WMED. The WMED hosts most invasive macrophytes, whereas the EMED has the lion’s share in polychaetes, crustaceans, molluscs and fish.
New records of the genus Pachygrapsus (Crustacea: Decapoda) from the central Mediterranean Sea with a review of its Mediterranean zoogeography

Published: May 2013

The occurrence of Pachygrapsus maurus and Pachygrapsus transversus is reported from the Maltese Islands for the first time on the basis of one specimen of P. maurus collected in 1990 and numerous recent specimens, and the distribution of the two species is mapped. The controversial presence of P. maurus in Italy is confirmed and two new sites for this species are reported, including the first for the mainland of Italy. The examination of the historical specimen of P. maurus from the Genova area revealed a misidentification of P. transversus; this record could be a result of ship-mediated transport. First notes on the habitat of P. maurus in the central Mediterranean Sea are given. Updated maps of the distribution of P. maurus and P. transversus in the Mediterranean are provided and the zoogeography of these species is revisited.
A 2-year intercomparison of the WAM-Cycle4 and the WAVEWATCH-III wave models implemented within the Mediterranean Sea

Published: May 2013

In this work we present the implementation of a wave forecast/hindcast system for the Mediterranean Sea at a 1/10º horizontal resolution and we show a first assessment of its performance by inter-comparing model results to observational data time series at selected points for the period 2000-2001. The system which is part of the POSEIDON-II operational system includes the WAM – Cycle4 and the WAVEWATCH-III wave forecast models (implemented within the same region) one way coupled with the non-hydrostatic version of the ETA atmospheric model which provides at 3-hour intervals the necessary wind velocity fields to the wave models. The same system but based on the WAM-Cycle4 wave model, has been used in the past for the production of the Aegean Sea wind and wave Atlas. Overall, the inter-comparison shows that both wave models are rather skilful in predicting the integral wave parameters with significant wave height skill scores in the range 0.85-0.90 and mean period scores in the range 0.77-0.83. It is also evident that WAM model has a tendency to overestimate mean wave periods while the opposite is true for WAVEWATCH-III model. Differences between the two models simulated spectra exist along the main passage of cyclonic systems over the Mediterranean Sea while in the wind seas dominated areas of the basin (the Aegean Sea for example) the two models show almost the same behavior.
Spatial and temporal variation of soft-bottom peracarid (Crustacea: Peracarida) infauna in the Canakkale Strait (Turkey)
Authors: ASLAN-CIHANGIR H. , PANCUCCI-PAPADOPOULOU M.A.
Published: May 2013

The biodiversity and distribution of soft-bottom peracarid crustaceans were analyzed in the south part of Canakkale Strait, a very important biological corridor between the Mediterranean and the Black Sea. Samples were collected seasonally from 11 coastal stations at depths ranging from 10 to 22 m. Moreover, qualitative samples were collected in summer from 7 stations (40 - 83 m depth) located in the middle part of the Strait. A total of 110 species were identified. Amphipods were the dominant group both in terms of species richness and abundance. Apocorophium acutum, Phtisica marina and Microdeutopus versiculatus were the most abundant species. A large number of rare species was recorded, leading to very low similarity values among stations. Six different feeding types were detected, with surface deposit feeders being the dominant one in the area. Significant differences in abundances and assemblage structure were detected along the eastern and western coasts of the Strait that could be attributed to food supply and sediment composition, depending on bottom current velocities. Possible relations of peracarids with the hydrological regime of the area are also discussed.

Catch and size selectivity of small-scale fishing gear for the smooth-hound shark Mustelus mustelus (Linnaeus, 1758) (Chondrichthyes: Triakidae) from the Aegean Turkish coast
Authors: CEYHAN T. , HEPKAFADAR O. , TOSUNOGLU Z.
Published: May 2013

Catch rate, CPUE, biomass ratios and size selectivity from traditional longline and trammel nets of Turkish coastal small-scale fisheries were investigated in order to describe the Smooth-hound shark (Mustelus mustelus) fishery. The SELECT method was used to estimate the selectivity parameters of a variety of models for the trammel nets inner panel of 150 and 170 mm mesh sizes. Catch composition and proportion of the species were significantly different in longline and trammel nets. While mean CPUE of longline was 119.2±14.3 kg/1000 hooks, these values for 150 and 170 mm trammel nets were 5.3±1.2 kg/1000 m of net and 12.7±3.9 kg/1000 m of net, respectively. Biomass ratios of the by catch to Smooth-hound catch were found to be 1:0.32 for 150 mm trammel net, 1:0.65 for longline and 1:0.73 for 170 mm trammel net. The estimated modal lengths and spreads were found to be 91.1 and 16.2 cm for 150 mm and 103.2 and 18.4 cm for 170 mm, respectively. The modal lengths of the species as well as the spread values increased with mesh size.
Synechococcus dynamics in the Levantine basin shelf waters (northeastern Mediterranean)
Authors: UYSAL Z. , KOKSALAN I.
Published: May 2013

The abundance of picoplanktonic marine cyanobacteria Synechococcus was measured at weekly intervals over a period of one year in the northern Levantine basin shelf waters. Synechococcuswas found more abundant during summer and early autumn and least during winter. Significant increases in abundances mostly occurred during very low nutrient concentrations either a week or two weeks after the nutrient enrichments. Cells were distributed homogenously in the water column due to intense mixing observed during winter. Despite the homogenous cell distribution attained during late autumn and winter, the magnitude of variation in cell abundances among depths was found greatest during August and September. Cell concentrations ranged from a minimum of 6.4 x 103 to a maximum of 9.2 x 104 cells ml-1 with an annual mean level of 2.5 x 104cells ml-1 at surface. Below the surface, it ranged from a minimum of 5.6 x 103 to a maximum of 8.0 x 104cells ml-1 with an annual mean level of 2.1 x 104 cells ml-1 at 25 m depth. Compared to surface and 25 m depth, lowest levels were attained at 50 m. At this depth, cell counts ranged from a minimum of 5.4 x 103to a maximum of 3.2 x 104 cells ml-1 with an annual mean level of 1.4 x 104 cells ml-1. Based on Pearson-product moment correlation analysis, a highly significant correlation between Synechococcusabundance and ambient temperature was observed.
Characteristics of Marine Recreational Fishing in the anakkale Strait (Turkey)
Authors: UNAL V. , ACARLI D. , GORDOA A.
Published: May 2013

The economic and harvest impacts of Marine Recreational Fishing (MRF) in Çanakkale Strait were analysed along with fishing policy, sociology and habits of fishers. Data sources included field survey data carried out along the entire length of the Çanakkale strait and policy information gathered from published sources. MRF policy is commendable, even in the fishing tourism sector, and is better developed than that in many other European countries. In Çanakkale, 9.9% of the population is recreational fishers. Recreational fishers are typically men (90%), primarily those between the ages of 25 and 49 yrs. The occupation of the recreational fishers ranged from self-employed (28%), students (28%), retired persons (22%) and public employees (15%), to currently-unemployed persons (7%). An analysis of diel behaviour showed that most recreational fishers preferred fishing during the day (56.1%), while the evening was the next most preferred time for fishing (18%), followed by the night-time (9.8%), while a substantial number of recreational fishers (16.1%) reported that they fished at any time of day. The most popular type of fishing was shore-based (68%), followed by boat-based (21%), and underwater fishing (11%). The mean daily fishing times were 6.07 h d-1, 6.18 h d-1 4.75 d-1 for boat-based, underwater and shore-based fishing, respectively. Summer and autumn were the preferred seasons for shore-based and underwater fishing, while autumn and winter were preferred for boat-based fishing. The highest Catch per Unit Effort (CPUE) was observed for boat-based fishing (2.77 kg h-1), followed by underwater (0.97 kg h-1) and shore-based fishing (0.81 kg h-1). The catch composition included 51 species, though the catch composition of each fishing type was mostly comprised of only 3 or 4 species. The impact of the MRF harvest was high (30% of commercial fishing), particularly for bluefish (Pomatomus saltatrix) and picarel (Spicara smaris) species. The economic impact of MRF was highly negative. Several indicators including the following revealed a high percentage of trading catch (47%) being conducted under the guise of a recreational label: annual fishing intensity, total costs, target species, and sales. At present, it is evident that the highly developed recreational fishing policy in Turkey is not sufficient to ensure that recreational fishing is sustainable or to prevent fishing conflicts in Turkey. This study revealed the need for establishing monitoring, control and surveillance programs to ensure the sustainability of fish resources and fisheries including MRF.

Authors: SIMBOURA N. , KURT SAHIN G. , PANAGOULIA A. , KATSIARAS N.
Published: May 2013

This study reports four alien polychaete species new to the marine fauna of Greece. These species are -Pseudopolydora paucibranchiata (family Spionidae),Paraprionospio coora (family Spionidae), Marphysa disjuncta (family Eunicidae), and Chaetozone corona(family Cirratulidae). Another species of Chaetozone, though not an alien one, Chaetozone gibber is reported here from Greek waters. All of them have been currently reported from the coasts of Turkey (Aegean or Levantine Seas). Pseudopolydorapaucibranchiata and Marphysa disjuncta, probably introduced to the region through ballast waters, seem to have been well established in the Mediterranean Sea. Chaetozone corona and Paraprionospio coorawere considered to be cryptogenic. Pseudolydora paucibranchiata was found in great densities in a very disturbed site, confirming the opportunistic character of this species. Chaetozone corona and Chaetozonegibber showed a wider distribution pattern, though their abundance increased in disturbed sites.Marphysa disjuncta was found in disturbed as well as in undisturbed sites along the coasts of Greece.Paraprionospio coora shows a distribution pattern indicating an opportunistic character. These new findings increase the number of polychaete species from the Hellenic Seas to 777 species.

Published: May 2013

A fleet of 326 bottom trawlers operate in Greek Seas and their landings represent approximately 30% of the total fish production in Greece. In this study, otter trawl landings data were analyzed in order to identify potential métiers. Landings data between 2002 and 2006 were used, collected from 42 ports in the Aegean and East Ionian Sea. A three-step procedure was applied to identify potential métiers: the first step involved a factorial analysis of the log-transformed landings profiles, the second step a classification of the factorial coordinates, and the third step a further aggregation of clusters based on expert knowledge. In all, six potential métiers were identified in the Aegean Sea, and five in the Ionian Sea. The most important target species were European hake (Merluccius merluccius), deepwater pink shrimp (Parapenaeus longirostris), red mullet (Mullus barbatus), caramote prawn (Melicertus kerathurus), picarel (Spicara smaris), cephalopods, bogue (Boops boops), anglers (Lophiusspp.), and Norway lobster (Nephrops norvegicus). Otter trawls in Greece use more or less the same gear with minor modification, and métier selection is basically reflected as a choice of geographical sub-area and hauling depth. The limitations of using landings profiles to identify métiers and the need for further verification are discussed.
Analysis of seasonal growth through the application of a multiple linear regression model on data from tag-and-recapture experiments
Authors: STAMATOPOULOS C. , CADDY J.F.
Published: May 2013

When the Brody coefficient K is subject to temporal variation, data from tag-and-recapture experiments permit analysis of seasonal growth. Temporal values for K can be estimated without using a pre-determined oscillating function and the impact of seasonality on annual growth can be analyzed more realistically. The method is applicable to intra-annual intervals of single or multiple cohorts.
Delayed ejaculation and alexithymia: what is the relationship?

Delayed Ejaculation (DE) is probably the least studied and understood of the male sexual dysfunctions (MSD). There is still little unanimity concerning its psychological/interpersonal aetiology. Previous studies found that MSD are strongly related with alexithymia, a multifaceted personality construct that describes a disturbance in the regulation of emotions.The aim of this study was to investigate the presence of alexithymia in men with DE and correlate alexithymia levels with DE severity. According to specific features of the symptoms, we hypothesized that alexithymia would not be correlated with this specific sexual disorder.

54 outpatients with a diagnosis of DE assessed at the Institute of Clinical Sexology and the Urology Department of Sapienza, University in Rome were enrolled in the study. DE was diagnosed after a specialist examination and according to Diagnostic and Statistical Manual of Mental Disorders -IV-TR criteria. Participants were provided with the Toronto Alexithymia Scale (20 items; TAS-20), a self-measure of the Intravaginal Ejaculation Latency Time and an ad hoc questionnaire to collect anamnestic data.

9.3% of patients could be categorized as alexithymics, 9.3% of them as borderline, while 81.4% of the sample was found to be non-alexithymic. The overall average TAS-20 score was 45.46. Results show that alexithymia is correlated neither with the presence of DE nor with its severity, in contrast to other MSDs, where this condition was found in about 30% of patients.

The data presented suggest that DE, although not correlated to alexithymia, is probably related to other psychogenic features such as hypercontrol configuration. This paper can contribute to the understanding of DE, by excluding one of the possible etiological factors, previously found to be important in the onset and the maintenance of the other MSDs. More studies are needed in order to better understand DE and provide recommendations about treatment.
„Nie tak i tak dalej, ale tak i nie tak dalej…”, czyli o tym, czym jest nielogiczność
Authors: Wołk Mariola
Published: May 2013

“Nie tak i tak dalej, ale tak i nie tak dalej…” ‘Not this way and so on, but this way and not so on…’ – the issue of illogicality

The article discusses the linguistic unit coś jest nielogiczne (‘something is illogical’), aiming to provide a description of its meaning, and an explicative formula which consists of indefinable expressions of the natural language. The semantic description of the unit is influenced by the issue of its reference, which is two-fold: the unit can refer to what someone said, as well as to what someone did. In order to pinpoint the distinctive features of the given expression, which is what determines its distinguishability, it is compared to a semantically close predicate, nonsens (‘nonsense’). Conclusions that flow from the analysis of nonsens had to be verified after a comparison with those obtained from the analysis of illogicality.

Ustalanie znaczeń symbolicznych w słowniku etnolingwistycznym
Authors: Niebrzegowska-Bartmińska Stanisława

Determination of meanings in an ethnolinguistic dictionary

The notion of symbol, though popular and commonly used, has not so far received a satisfactory operational definition, i.e. a methodology of description that would allow to assign specific symbolic meanings to images in a foreseeable, “controllable” way. This is revealed by the different symbolic meanings which dictionaries assign to the same images. The paper uses examples from the Lublin Słownik stereotypów i symboli ludowych ‘Dictionary of stereotypes and folk symbols’ to question the rules for determining symbolic meanings and the “linguistic and cultural proofs” connected with the assignment of those senses – the rules that link the sun with life, truth and perfection, fire with love and passion, light with the God and heaven, dew with life-giving force and male sperm, wind with life-giving spirit, rainbow with the sign of peace, &c. The article reveals that the symbolic sense is sometimes prompted by the etymology, metaphorical meanings, parallel constructions, equivalence, or may also result from the genre convention of the text (an erotic, a dream book, a wishing carol), or finally from the beliefs and practices of bearers of folk culture. Regardless of all those attempts at determining symbolic meanings, the formulation of such meanings remains a hypothesis of a kind. Texts, especially artistic ones (where also folk texts belong), contain an unclosed semantic potential and remain unsaid, open and susceptible to new symbolic readings.
Z przeszłości gwar Wielkopolski wschodniej

From the past of the dialects of eastern Greater Poland. Based on the acts of civil status from Golina and Kawnice of 1821

During the period of partitions, eastern Greater Poland was in a special situation. It was doubly a linguistic periphery, both with regard to the rest of the region and to the major centres of cultural life (Cracow and Warsaw). In the 19th c., the principle “we speak as we write, and we write as we speak” was in wide use, meaning that the manuscripts from those times can be used to analyze the non-normalized language. Based on this assumption, the article discusses acts of civil status from the year 1821 from Golina and Kawnice (Konin municipality).

Hiponimy miejsca w polskiej Słowosieci i amerykańskiej bazie WordNet
Authors: Dobrowolska Marta
Published: May 2013

Hyponyms of place in Polish and American wordnets

The aim of the paper is to compare the sets of hyponyms of place in Polish and American wordnets. Polish “Słowosieć” and American WordNet are thesauri which define the meaning of an individual lexeme by the lexical-semantic relations existing between this and other lexemes. The researched material consists of several thousand of synsets (sets of lexemes referring to a common concept) which have been linked by interlingual, lexical-semantic relations to the synsets of English lexemes in a process of mapping of a fragment of the Polish wordnet to the American database. An analysis of particular cases illustrates the basic issues concerning the procedure of mapping, first of all the problem of choosing a foreign synonym for the original word. It also shows the incompatibility of the corresponding fragments of the Polish and English lexical systems, which is usually not reflected in dictionaries and other glottodidactical publications. Differences between the structures of semantic trees of the two languages result partly from different assumptions made by the authors of both wordnets, and partly from language-specific factors, such as different word-formation systems or different ways in which some objects from the real world are conceptualized.
Comparison of CEDIA FK506 Assay With HPLC/MS/MS in a Large Cohort of Pediatric Patients
Authors: Lower Darla R. , Cropcho Lorna , Rosendorff Adam
Published: May 2013

FK506 (tacrolimus), a macrolide immunosuppressant, is widely used in pediatric transplant patients, but a relatively narrow therapeutic window in children vs adults requires close and accurate monitoring of whole blood FK506 levels. High-pressure liquid chromatography/tandem mass spectrometry (HPLC/MS/MS)–based assays have been viewed as the gold standard but are more time and labor intensive than cloned enzyme donor immunoassay (CEDIA). To analyze differences between the 2 assays, we assayed FK506 in 348 split samples simultaneously by both methods. A further 70 samples were stratified by organ transplantation type: cardiac (13%), renal (23%), small bowel (22%), or liver transplantation (42%). Results were analyzed using standard statistical techniques for method comparison. CEDIA overestimated the FK506 value relative to HPLC/MS/MS by more than 20% in 40% of cases (139/348), whereas CEDIA underestimated the FK506 value relative to HPLC/MS/MS by more than 20% in 13.5% of cases, for a total inaccuracy of 53% using a ±20% cutoff. Only 28% of samples (99/348) measured by CEDIA were within 10% of the value obtained by HPLC/MS/MS. Bland-Altman analysis showed a mean bias of 9.5% in favor of CEDIA over HPLC/MS/MS (95% confidence interval, 6.1%–12.9%). Positive bias was greatest for liver transplant and R2 values were lowest for intestinal transplant patients, indicating that HPLC/MS/MS may be a better option for this pediatric transplant subgroup.
Total synthesis of (+)-spirastrellolide A methyl ester: Challenges and discoveries
Authors: Paterson Ian , Maltas Philip , Anderson Edward A.
Published: May 2013

This review focuses on recent synthetic efforts by our group towards spirastrellolide A methyl ester, a complex marine macrolide containing two spiroacetal ring systems that shows promising anticancer properties. The evolution of a flexible, modular strategy leading to the first total synthesis of (+)-spirastrellolide A methyl ester, and the associated challenges overcome, are highlighted, particularly in dealing with the initial structural ambiguities. This work enabled the development of an improved second-generation synthesis, which revealed a critical dependence of the key macrolactonization step on the nature of the protecting groups in the linker region between the spiroacetal motifs.

We have shown the application of the hybrid approach to design and rapidly generate a library of novel natural product-like compounds, which may have interesting biological features, using metathesis and/or cycloaddition reactions as key steps.
Copland in Argentina
Authors: Hess Carol A.
Published: May 2013

Perhaps more than any other US composer, Aaron Copland is associated with Pan Americanism, a contradictory and often unbalanced set of practices promoting North-South economic and affective ties since the nineteenth century. Copland visited Latin America on behalf of the US government four times over the course of his career. He also befriended and taught Latin American composers, wrote about Latin American music, and composed several Latin-American—themed works, including the well-known El salón México. Focusing on one such encounter—Copland's three visits to Argentina (1941, 1947, 1963)—this article examines in detail Latin American opinion on Copland's cultural diplomacy, thus challenging the prevalent one-sided and largely US perspective. My analysis of these Spanish-language sources yields new biographical data on Copland while questioning recent assessments of his Latin American experience. I also illuminate the composer's conflicted approach to modernism, intimately connected to his desire to communicate with a broad public and to assert national identity. The crisis of modernism not only played itself out in some surprising ways in Argentina but also informed Copland's profoundly antimodernist vision of Latin American music, one rooted in essentialism and folkloric nationalism and which ultimately prevailed in the United States throughout the late twentieth century.
Haydn's Solar Poetics
Authors: Sisman Elaine
Published: May 2013

The sun has long been a potent symbol of worldly power, mythological cosmology, Christian revelation, and philosophical enlightenment. To conjure with it musically is to open a vast field of the associative possibilities of illumination and its others: figures of emergence, ascension, power, fatal strength, attenuation, obscurity. In his symphonic trilogy on the times of the day—nos. 6 (Le matin), 7 (Le midi), and 8 (Le soir)—Haydn traces the diurnal movement of the sun across all three works in ways that reveal a sophisticated understanding of the sun's many cultural resonances. This opus constitutes, in effect, Haydn's debut at the Esterházy court in 1761, a year in which the Transit of Venus across the sun attracted local and global fascination and intense astronomic study. Beyond demonstrating his cultural range to the court, Haydn's focus on the sun's trajectory also helps to explain many of the puzzling musical features of the trilogy, especially the unusual slow movements. These works cast new light on Haydn's return to musical settings of the diurnal cycle at the dusk of his career, in The Creation (1798) and The Seasons (1801), and reflect the Enlightenment composer's engagement with multiple fields of knowledge and experience.
MOFIA: a chemoinformatic webserver for the prediction of CO2 adsorption in metal organic frameworks (MOF)
Authors: Fernandez Michael , Daff Tom D , Trefiak Nicholas R. , Woo Tom K.
Published: May 2013

Nanoporous metal-organic framework (MOF) materials are strong candidates for energy efficient carbon capture and storage (CCS) technologies. A total of ∼20,000 hypothetical MOFs were ab initio screened for CO2 adsorption using grand canonical Monte-Carlo (GCMC) simulations. Novel radial distribution function (RDF) scores were modified for periodic systems to predict the CO2 adsorption of MOFs using chemoinformatic models. The test set predictions yielded accuracies of 0.76 and 0.85 at 0.1 bar and 1 bar, respectively. The models were used to screen a large database for high performing MOFs and the top 100 structures were successfully validated by GCMC simulations. The chemoinformatic predictors of the CO2 adsorption of MOFs are available online at http://titan.chem.uottawa.ca/woolab/MOFIA/#carbondioxide.
