Transforming Pedagogical Approaches Using Tangible User Interface Enabled Computer Assisted Learning
Authors: Istenic Starcic Andreja , Turk Žiga , Zajc Matej
Published: December 2015

Traditional computer assisted learning is influenced by novel user interfaces, such as tangible user interfaces, support cognitive processes and concept modelling, assisted by multiple representation. The manipulative properties of the tangible user interface’s physical manipulatives, for example, enhance passage between physical and virtual representations. It therefore provides a transition between stages in the reasoning process. In social modes of learning, physical manipulatives provide assistance in all social modes: individual, pairs, small groups and teacher up front. Computer supported collaborative learning is provided in the physical presence of learners manipulating on the same tabletop device. A systematic review of scientific articles applying qualitative and quantitative approaches was undertaken. The content analysis was conducted to examine pedagogical approaches based on the two models of Bruner (1966) and Gagné (1985).
Les séries qui nous quittent, les séries que nous quittons
Authors: Garcia Tristan
Published: December 2015

À partir de l’analyse de quelques séries interrompues avant leur terme, je propose une réflexion libre sur les œuvres télévisuelles mortes avant d’être finies. Le sentiment suscité alors chez le spectateur peut être rapproché de celui éprouvé lors d’une rupture amoureuse ou d’un deuil. En distinguant par une rapide phénoménologie de nos affects de spectateurs les séries qui nous quittent, les séries que nous quittons et les séries que nous accompagnons jusqu’à leur fin, je défends l’idée que l’expérience de l’amateur de séries télévisées s’apparente à celle d’une relation sentimentale, menacée sans cesse par la possibilité de la mort de l’autre, et j’avance l’hypothèse selon laquelle notre empathie pour les personnages de série serait en fait fondée sur notre empathie pour la forme fragile des séries elles-mêmes, qui nous promettent l’infini en s’exposant épisode après épisode et saison après saison à un arrêt brutal.
Échos lointains pour reprise dissonante : la série catalane Infidels
Authors: Houdiard Jennifer
Published: December 2015

La série Infidels (TV3, 2009-2011), diffusée sur la chaîne catalane ainsi que sur internet durant trois saisons, était attendue comme une sorte d’adaptation de séries « féminines » américaines telles que Sex and the City (HBO, 1998-2004) ou Desperate Housewives (ABC, 2004). Cependant, une fois les premiers épisodes diffusés, Infidels fut rapidement reconnue comme une production originale, à double titre. En effet, loin de se limiter à transposer au cadre barcelonais des fictions télévisées venues des États-Unis, les scénaristes ont réussi à concevoir une fiction « maison » de qualité, fidèle à l’esprit de la chaîne TV3 par son ancrage dans la re-création d’un contexte catalan identifiable comme réel et réaliste par le spectateur. Si des « clins d’œil » aux séries américaines citées plus haut ou à la série britannique Mistresses (BBC One, 2008-2010) sont aisément perceptibles, ils se limitent en général à un jeu sur l’intertextualité. Au-delà de l’originalité et de la « catalanité » d’Infidels, les journalistes et critiques ont célébré le traitement profondément novateur des figures féminines et, plus généralement, la remise en question encore inédite des clichés et des rôles traditionnels dévolus aux femmes ainsi qu’aux personnages féminins qui peuplent la grande majorité des fictions télévisées. Les cinq protagonistes de la série ont en commun l’infidélité sexuelle et sentimentale, il est vrai, mais à mesure que les épisodes s’enchaînent, la quête ontologique qui sous-tend la diégèse et lui sert de fil conducteur se révèle de plus en plus clairement : Paula, Lídia, Cruz, Joana et Arlet sont, finalement, infidèles aussi bien aux rôles de genre traditionnels qu’au modèle incarné par le nouvel « Éternel féminin » des médias de masse, et ce n’est qu’ainsi qu’elles peuvent devenir fidèles à elles-mêmes.
Continuité, canonicité et complétude dans Doctor Who
Authors: Favard Florent
Published: December 2015

Cet article explore le rapport complexe à la continuité qu’entretient la série britannique Doctor Who (BBC One, 1963-1989, 2005-), en se penchant sur sa multi-auctorialité d’un point de vue diachronique puis synchronique, et en détaillant un monde fictionnel dispersé sur de multiples supports suivant un processus qui ne se conforme pas à la définition stricte du transmedia storytelling. La période de production la plus récente du programme (depuis 2010) est aussi analysée, en ce qu’elle révèle une tension entre respect et reconfiguration de la continuité. Les degrés de canonicité des diverses œuvres liées à la série-mère, la réception par les publics et les processus de production du programme sont passés en revue afin de dresser le portrait le plus complet d’une œuvre transmédiatique qui trouve sa dynamique dans l’ellipse via le procédé de complétude rétroactive, dans un développement qui évoque le rhizome plutôt que l’arbre, et dans un renouvellement constant et fluide de ses enjeux esthétiques et économiques.
Religious aesthetics in Game of Thrones
Authors: Wells-Lassagne Shannon
Published: December 2015

George R.R. Martin’s series of novels A Song of Fire and Ice is notable for its world-building, particularly in regards to its representation of a fairly large variety of co-existing religions (though only three are given significant authorial attention). When adapting the novels to the small screen, shorthand for these different religions is almost purely visual: rituals are heightened, and imagery is emphasized. In this sense, the series subtly emphasizes the importance of ceremony and aesthetics in converting and sustaining their “flocks”: conversion is not based on ideology, since it remains rudimentary at best in the time allotted to this subject, but on theatrics. In so doing, Game of Thrones (HBO, 2011-) makes a statement, be it voluntary or not, on both religion and politics in contemporary American culture.

Determination of digestive proteolytic profile in the larvae of Dyspessa palidata (Staudinger) (Lepidoptera: Cossidae)
Authors: Mardani-Talaee M. , Zibaee A.
Published: December 2015

Digestive proteolytic profile was determined in the larvae of Dyspessa palidata (Staudinger), which is the most important pest of Alliaceae in Europe and Iran. Compartmentalisation of the proteolytic activities by considering soluble and membrane-bound fractions revealed that soluble fractions of the whole midgut preparations had higher general proteolytic activity than membrane-bound fractions. Also, four proteolytic bands were observed in the soluble fraction of the total midgut preparation in electrophoresis. Compartmentalisation of the specific proteases revealed presence of trypsin, elastase, aminoand carboxy peptidases in posterior midgut but the highest activities of other proteases were found in anterior midgut. The highest activity of general protease was found at pHs of 6 and 8. Also, pH dependency of trypsin, chymotrypsin and elastase were found at values of 8, 7-8 and 9 but cathepsins had the optimal pH at 6. Exopeptidases showed the optimal value at pH of 7 although carboxypeptidase showed same activity at values of 6 and 7. The inhibitory concentrations 50% (IC50) of AEBSF.HCL on trypsin, chymotrypsin and elastase proteases were found to be 3.69, 3.31 and 4.09 mM, respectively. IC50 concentrations of TLCK, SBTI and TPCK significantly inhibited trypsin and chymotrypsin activities. IC50 of E-64 were 3.67 and 4.16 mM on cathepsin B and L but cystatin revealed 5.22 and 4.48 mM concentrations on cathepsin B and L, respectively. EDTA and phenathroline as metalloproteinase inhibitors had IC50 of 3.25 and 3.91 mM on general proteolytic activity. Results of the current study revealed larvae of D. palidata utilised different proteases to increase digestive efficiency when they fed on the host plants containing several toxic molecules.
Metamorphic and plutonic rocks of northernmost Ellesmere Island, Canadian Arctic Archipelago
Authors: Frisch T
Published: December 2015

Information obtained from reconnaissance mapping between Cape Aldrich and Phillips Inlet has resulted in an extension of previously defined limits of areas underlain by metamorphic and plutonic rocks in the Northern Ellesmere Fold Belt of the Franklinian
Geosyncline. Metamorphic rocks are most abundant between M'Clintock and Phillips Inlets; they occur in lesser amount between Cape Aldrich and M'Clintock Inlet. Amphibolite facies gneisses and schists tend to be restricted to the northernmost coasts, whereas greenschist facies rocks form extensive
terrains inland. Metamorphism appears to have been of Barrovian type and the highest grade exposed is that of the kyanite zone. Retrogressive metamorphism, promoted by cataclasis, was particularly pronounced in the Cape Columbia area. Three new K/ Ar age determinations on metamorphic rocks from the
Cape Columbia area yield Middle Ordovician to Early Devonian dates but field evidence indicates that at least part of the northern Ellesmere metamorphic complex is of preMiddle Ordovician age. Possible remobilization of metamorphic basement on Ayles Fiord in mid-Paleozoic time is suggested by a new
K/ Ar age determination. Plutonic activity appears to have been particularly active in Early Devonian time. A deformed, partly layered gabbro-peridotite body of tholeiitic affi nity has intruded metamorphic rocks at Cape Fanshawe Martin. A K/ Ar age determination on biotite from the intrusion
indicates 376 ± 16 m.y. as a minimum age of crystallization. Two alpine-type serpentinite massifs occur near the head of M'Clintock Inlet and were intruded by small felsic sheets and plugs, one of which has been dated (hornblende K/ Ar) at 390 ± 18 m.y. South of Cape Richards, a zoned
complex of alkalic syenite bordered by quartz monzonite has intruded pre-Middle Ordovician metamorphic rocks. A hornblende K/ Ar date of 390 ± 18 m.y. for the quartz monzonite probably gives a reliable minimum age of crystallizat ion. A granitic pluton (biotite K/ Ar age 345 ± 15 m.y.) at
the mouth of Phillips Inlet is bordered by a narrow, staurolite-kyanite-si llimanite-bearing contact aureole and is probably related to nearby smaller felsic plutons (biotite K/ Ar age : 325 ± 14 m.y.), which earlier have been interpreted to be mesozonal to epizonal intrusions emplaced during a
Middle Devonian to Mississippian orogeny.
The Arthropod Branchiocaris N. Gen., Middle Cambrian, Burgess Shale, British Columbia
Authors: Briggs D E G
Published: December 2015

A study of new specimens of the bivalved arthropod Protocaris preriosa Resser, 1929 from the Burgess Shale has added much information to the original description, and the species is removed to a new genus Bra11c/1iocaris. Prorocaris marshi Walcott, 1884 and
Dioxycaris arge11ra (Walcott, 1886) are also redescribed to facilitate comparison. The cephalic region of Bra11chiocaris preriosa bore a paired antenna anterior to a pair of stout appendages which may have been chelate. Suboval valves, the dorsal margin terminating anteriorly and posteriorly in a
small pointed process, covered the anterior of the body. The trunk included about 46 divisions followed by a telson bearing a pair of short pointed processes. The lamellate trunk appendages may have been biramous, with a short, segmented proximal element. The animal probably swam near the seabed by
metachronal movements of the lamellate appendages, which may also have functioned in respiration. B. pretiosa shows closest affinities to the branchiopod Crustacea among extant arthropods but is considered unlikely to represent a direct evolutionary predecessor of this group. The trunk of Protocaris
marshi included about 65 divisions; the tel son processes were elongate and curved. The appendages are unknown. The carapace of Dioxycaris arge11ta is similar in outline and size to that of Branchiocaris preliosa but the only known specimen is poorly preserved and lacks evidence of the soft-part
morphology.

Detailed mineralogical and chemical analyses have been carried out on Lower Cretaceous shale of northeastern British Columbia in order to evaluate the degree of diagenesis, to differentiate and correlate zones within the thick shale sequences, and to assess
potential sediment sources.
Sedimentology of the Archean Yellowknife Supergroup at Yellowknife, District of Mackenzie
Authors: Henderson J B
Published: December 2015

At Yellowknife the Jackson Lake and Burwash Formations of the Yellowknife Supergroup represent contrasting sedimentary environments at the margin of an Archean basin in the Slave Structural Province. The Jackson Lake Formation, exposed on the west s ide of
Yellowknife Bay, consists of a local discontinuous basal conglomerate derived largely from the thick mafic volcanic sequence that it unconformably overlies. The remainder of the formation consists of approximately 1, OOO feet ( 300 metres) of cross bedded felsic volcanic lithic wackes with minor
thin beds or lenses of conglomerate also largely of silicic volcanic derivation. The formation is a terrestrial braided river deposit that is considered to be the basin margin equivalent of the Burwash Formation that occupies the main part of the basin. The Burwash Formation, exposed on the east s
ide of Yellowknife Bay, consists of approximately 15, OOO feet (4, 500 metres) of interbedded greywackes and mudstones and shows many of the features characteristic of turbidites. Analysis of the sedimentary structures indicate that the turbidites were derived from the west, possibly from an area
occupied by an extensive granitic terrain, and accumulated in depositional fan valleys on a submarine fan complex near the margin of a large sedimentary bas in. The high percentage of dominantly felsic volcanic rock fragments, together with abundant quartz and feldspar, and minor but ubiquitous
granitic rock fragments in the greywackes, indicates a mixed silicic volcanic and granitic provenance. The modal and chemical composition and volumetric abundance of these sediments indicates an extensive sialic crust prior to the accumulation of the Yellowknife Supergroup at
Yellowknife.
Devonian stratigraphy, west-central Ellesmere Island, Arctic Archipelago
Authors: Trettin H P
Published: December 2015

A Devonian succession in west-central Ellesmere Island, about 5.2 km (3.2 miles) thick, consists mainly of elastic sediments with lesser amounts of carbonates and small amounts of evaporites. The strata are assigned to the previously established Cape Phillips,
Imina, Eids, Vehdom Fiord, Blue Fiord, and Hecla Bay Formations, and to the newly erected Red Canyon River and Strathcona Fiord Formations. The Early Devonian record embraces adjacent parts of the Hazen Trough, a deep-· water basin characterized by starved-basin and flysch sedimentation, and of
the Franklinian miogeocline. A southeastward, cratonward advance of the Hazen Trough, which had commenced in Early Silurian time , continued into the earliest Devonian (early Lochkovian); subsequently, shore and shelf prograded in westward and southwestward directions . "Reefs" developed at shelf
margin in late Early Devonian (late Pragian and Zlichovian) time. Initial movements of the cratonic Bache Peninsula Arch in mid-Early Devonian (latest Pragian-early Zlichovian) time produced an unconformity in the central and eastern parts of the study area. Erosion was followed by alluvial
sedimentation, in turn succeeded by elastic, carbonate and evaporitic deposition in lagoonal settings. Strata of latest Early and earliest Middle Devonian (Dalejan and early Eifelian) age demonstrate the transformation of the miogeoclinal carbonate shelf into a fluvia l molasse basin. Fluvial
deposition, first (Eifelian and early Givetian) by southwestward- flowing meandering rivers and then by braided streams, continued until about e arly late Devonian (early Frasnian) time. Clastic deposits of earliest Devonian age were derived mainly from northerly sources (Pearya and possibly
northernmost parts of the Caledonian orogen), those of midEarly Devonian age from the cratonic Bache Peninsula Arch, and those of Middle to Late Devonian age from a variety of northerly to southeasterly sources. The source terrains consisted mostly of metamorphic-plutonic rocks of sialic
composition, but uplifted parts of the Hazen Trough were the source for chert conglomerate. The metamorphic sources of the lowermost Devonian strata were of greenschist facies and the source of younger strata was of amphibolite or higher grade.
Lower Devonian (Lochkovian) biostratigraphy and brachiopod faunas, Canadian Arctic Islands
Authors: Smith R E
Published: December 2015

Collections from measured sections of Lower Devonian, Lochkovian rocks from the Canadian Arctic Archipelago were examined with emphasis on the paleontology and paleoecology of the contained brachiopod faunas. The brachiopods offer a reliable basis for correlation
of Lochkovian strata in the Arctic but supplementary data from conodonts, fishes, graptolites, and trilobites are invaluable. The Lochkovian Arctic brachiopods are both numerous and diverse and possess a marked Old World provincial aspect. Correlative faunas are found in the Yukon Territory, Nevada,
Bohemia, Podolia, and the Urals. On Baillie Hamilton Island, Lochkovian strata exhibit a series of successive communities produced by an overall upward-shallowing trend which is a direct result of active tectonism of the Boothia Uplift. The communities from deepest to shallowest, in ascending order
are: Graptolite, Notoparmella-Arctispira, Iridistrophia-MesodouvillinaSchizophoria, Gypidula-Atrypa-Schizophoria, Coral, and Ostracode. Sections from Prince of Wales Island also show shallowing trends but sections are not as thick and community succession is not as well developed or evident as in
the rocks on Baillie Hamilton Island. The Boothia Uplift was dominant in controlling type and amount of sediment deposited during Lochkovian time in adjacent regions of the Arctic Islands. Carbonate rocks of that age are unusually thick because of Boothia-derived elastic influx. The uplift destroyed
the lagoonal, semi-restricted environment occupied by the Silurian Atrypella Community (Read Bay Formation) and initiated new environments favourable to the radically different Lochkovian communities. The carbonate rocks range from lime-mudstones to grainstones to dolomites. The environments of
deposition range from deep subtidal to intertidalsupratidal. New brachiopod taxa include: Isorthis bistria, Protocortezorthis quadriforma, Protocortezorthis carinatus, Dalejina devonensis, Schizophoria fossula fossula, Schizophoria fossula transversiforma, Schizophoria protonevadaensis, Gypidula
pelagica pyraforma, Gypidula dyerensis, Leptaena nassichuki, Iridistrophia johnsoni, Iridistrophia thorsteinssoni, Barbaestrophia bieleri, Mesodouvillina musculusvarius, Mesodouvillina tuberosa, Mesodouvillina equicosta, Asymmetrochonetes spinalonga n. gen., Machaeraria obesa, Ancillotoechia gutta
rotunda, Ancillotoechia magnaplica, Ancillotoechia plicaminor, "Tadschikia" crassiforma crassiforma, "Tadschikia" crassiforma producta, Linguopugnoides uyenoi, Notoparmella costalata, Arctispira canadensis n. gen., Coelospira exilicosta exilicosta, Coelospira exilicosta orbita, Cyrtina maclennani,
Acanthospirifer macdonaldi, and Acanthospirifer norfordi.
Lower Ordovician Trilobites from the Summerford Group at Virgin Arm, New World Island, Northeastern Newfoundland
Authors: Dean W T
Published: December 2015

Ordovician trilobites from Unit B, the third oldest of six units into which the Summerford Group on New World Island, northeastern Newfoundland, has been subdivided, occur in a volcanic terrain and include Geragnostus sp., Scotoharpes sp., Bergamia? sp.,
Paratretas pis terranovica gen. et sp. nov., Pseudosphaerexochus (s. 1.) sp., Encrinuroides hornei sp. nov., Ischyrophyma sp., odontopleurid gen. et sp. undetermined, Metopolichas cf. M. verrucosus (Eichwald) , Illaenus (s. l.) sp. and Annamitella? insulana sp. nov. The assemblage does not have an
exact counterpart elsewhere, but the b athyurid Annamitella? Indicates affinities with Lower Ordovician faunas in Maine, North Wales, Argentina, Vietnam and southern U.S. S. R. The Metopolichas indicates Balto-Scandinavian affinities and suggests that the age of the fauna is highest Arenig or lowest
Llanvirn Series, a conclusion generally supported by the remainder of the assemblage.
Middle silurian ludlovian and wenlockian sponges from Baillie-Hamilton and Cornwallis islands, Arctic Canada
Authors: Rigby J K , Chatterton B D E
Published: December 2015

The Silurian sponge fauna described here from Baillie-Hamilton and Cornwalls islands is one of the most diverse known from North America. The fossils are from Wenlockian-Ludlovian age deposits of the Cape Phillips Formation, which accumulated on the slope and in
the basin of the Franklinian Geosyncline. The Cape Phillips Formation consists of interbedded shale, calcareous shale, and limestone, and most of the fossils are found in allochthonous limestone beds, mass movements having transported much of the fossil material downslope. Silurian sponges described
here are representative of a distinct sponge biogeographic province that occurs north and northwest of a line along the Transcontinental Arch and contrasts with one to the southeast where sphaerocladine lithistid and heteractinid calcareous sponges are dominant. New genera within the demosponges
include the rhizomorine Parodospongia and the orchocladines Antrospongia and Cauliculospongia. New hexactinellid genera include Corticulospongia and Lumectospongia. New species described here include the rhizomorines Haplistion frustrum and Parodospongia euhydra and the extensive orchocladines
Antrospongia aberans, Aulocopium nana, Calycocoelia micropora, Cauliculospongia solida, Dunhillia fistulosa, D. megaporata, D. pluraliporosa, Patellispongia alternata, Perissocoelia (?) gelasinina, Perissocoelia (?) spinosa, Psarodictyum attenuatum, and Somersetella amplia. Astylospongiella (?)
lutera and Astylospongiella striola are the only new representatives of the Sphaerocladina. The hexactinellid Amphidiscosa are represented by Lumectospongia uncinata n. gen. et sp. and the Lyssacinosa by the new Corticulospongia floccosa n. gen. et sp. and Dictyospongia apache n. sp. Carpospongia
globosa (Eichwald, 1830) is reported here from North America for the first time. The broadly distributed Archaeoscyphia minganensis (Billings, 1859), Hindia sphaeroidalis (Duncan, 1879), and species of Patellispongia and Psarodictyum add "universal" elements to the
assemblage.
Walcott's lower cambrian olenellid trilobite collection 61k, Mount Robson area, Canadian Rocky Mountains
Authors: Fritz W H
Published: December 2015

In 1913 Walcott described well preserved olenellid trilobites from the Mount Robson area that "make up a subfauna in the upper portion of the Lower Cambrian that has not been found elsewhere." Recent field studies indicate the "unique" 61k collection came from a
glacial moraine containing a mixture of fossils from the upper Nevadella Zone and lower Bonnia-Olene/lus Zone. The source horizons for most of the 61k taxa were found in nearby sections, permitting an enlarged description of the fossils and a presentation of their ranges. Below the productive 61k
source horizons are (in ascending order) Nevadia weeksi Walcott, Nevadia parvoconica sp. nov., and Nevadella mountjoyi sp. nov. First in the source horizons is Nevadella eucharis (Walcott) followed by Nevade/la perjecta (Walcott). Above N. perjecta is a narrow (0.3 m) interval containing the
boundary between the Nevadella and Bonnia-Olenellus zones. Found above the boundary interval is Mummaspis occidens (Walcott) gen. nov., followed by Olenellus truemani Walcott, Laudonia bispinata Harrington, Olenellus truncatooculatus sp. nov., and Mummaspis oblisooculatus gen. et sp. nov. Olenellus
mura/ensis sp. nov. was not found in outcrop, but is known to coexist with 0. truncatoocu/atus on some 61k slabs. It is presently only a guess that Laudonia amputata sp. nov. came from the productive interval. It was not found in outcrop and is not associated with other taxa on 61k slabs. Gabriellus
lanceatus gen. et sp. nov. occurs in the medial Bonnia-0/enellus Zone, well above the main producing horizons. Numerous locations in the North American Cordillera can be correlated with the beds containing the 61k taxa. The abrupt faunal change at the boundary between the Nevadella and
Bonnia-Olenellus zones is briefly discusse
Geology of the Lac Ghyvelde - Lac Long area, Labrador and Quebec
Authors: Thomas A , Culshaw N G , Currie K L
Published: December 2015

The Lac Ghyvelde-Lac Long area exposes mainly granulite-grade paragneiss, gabbro, anorthosite, and charnockite. The Wilson Lake block, the northern two-thirds of the area, grades from sillimanite-cordierite assemblages in the north to sillimanite-orthopyroxene in
the south. Sapphirine-bearing assemblages occur in both parts, and sapphirine-quartz assemblages occur in the southern part. Metamorphism and plutonism of Paleoproterozoic or Archean paragneisses of the Wilson Lake block occurred about 1650 Ma during the Labradorian orogeny. They have been variably,
but slightly, overprinted by Grenvillian (1200-1000 Ma) orogeny. Variably metamorphosed gabbro, anorthosite, and monzonite of the Atikonak River massif intrude the Wilson Lake block in the central part of the area. The massif consists of anorthosite suite rocks, probably of Labradorian age, intruded
by tholeiitic rocks about 1120 Ma. The deformed and metamorphosed Lac Long igneous suite, characterized by orthopyroxene-garnet-two feldspar assemblages, underlies the southern part of the area. This suite was emplaced at 1225 Ma and metamorphosed at 1008 Ma under amphibolite to granulite grade
conditions. The Lac Long lineament, a broad zone of cataclasis, crosses the area from east to west. At present it separates granulites of Labradorian age from those of Grenville age. It appears to be a major and persistent crustal break. The Lac Ghyvelde-Lac Long area exhibits deep crustal rocks
brought to shallower depth and imbricated northward during Grenvillian orogeny. In this region the orogeny affected crust already thickened and metamorphosed during the previous Labradorian event.
Middle carboniferous fusulinacean biostratigraphy, northern Ellesmere Island (Sverdrup Basin, Canadian Arctic Archipelago)
Authors: Groves J R , Nassichuk W W , Lin R , Pinard S
Published: December 2015

The Sverdrup Basin is an elongate pericratonic depression underlying much of the Canadian Arctic Archipelago. The oldest rocks in the basin, nonmarine marlstones that constitute the Viséan Emma Fiord Formation, occur in isolated structural depressions along
the southern margin and in the centre of the basin. The Borup Fiord Formation, consisting mainly of marine and nonmarine siliciclastics, was the first widespread sedimentary unit to be deposited following initial rifting and collapse of the basin. At its type section on northern Ellesmere Island,
the Borup Fiord Formation contains a thin marine limestone with biseriamminid and asteroarchaediscid foraminifers of Serpukhovian (Chesterian) age. This limestone is the only datable unit within the entire Borup Fiord Formation. Continued rifting and subsidence of the Sverdrup Basin led to
predominantly marine conditions, which are recorded at the basin margins by a thick succession of bioclastic limestone belonging to the Nansen Formation. The presence of primitive fusulinaceans from the lower several metres of the Nansen in its type area strongly suggests an early Bashkirian
(Morrowan) age. Erosional relief, coupled with biostratigraphic evidence, indicates an unconformable contact between the Borup Fiord and Nansen formations. Successively higher deposits within the lower 350 m of the Nansen are characterized by fusulinacean assemblages that range from Bashkirian
through early late Moscovian (early Desmoinesian) time. Fusulinaceans are particularly useful in correlating Middle Carboniferous strata in the Sverdrup Basin with standard reference sections in subArctic North America, Russia, and elsewhere in the Commonwealth of Independent States. The Nansen
contains species of primitive pseudostaffellins previously documented from the Bashkirian stratotype on the western slope of the south Urals. A lineage for the origin of the Fusulininae is tentatively proposed. Evolutionary inferences suggest that both pseudostaffellin and fusulinin clades arose in
early Bashkirian time from the splitting of plectostaffelloid stock. One new species, Plectostaffella reitlingeri Groves, is described.
Conodont biofacies of lower to lower middle ordovician megaconglomerates, Cow Head group, western Newfoundland
Authors: Pohler S M L
Published: December 2015

Clasts from three conglomerate and megaconglomerate horizons in the Cow Head Group of western Newfoundland were sampled for conodonts to determine age and faunal composition. The Cow Head Group represents a fragment of the paleoslope of the Cambro-Ordovician
Iapetus Ocean that was thrust upon age-equivalent shelf strata of the Port-au-Port and St. George groups. Although shelf and slope facies are preserved in sequence, the record of shelf break and upper slope facies is only retained in clasts of the conglomerate units of the Cow Head Group. The Arenig
interval with the thickest conglomerate units was chosen for the study. Conodonts from the shelf edge and upper slope environment were compared and correlated with slope and shelf faunas. The 300 samples collected from limestone clasts yielded 12 492 well preserved conodonts with a low colour
alteration index of 1.5 to 2.0. Altogether 132 form- and multielement species were determined, and one new genus (Texania) and several new species (Texania heligma, T. teras, Prioniodus marginalis and P. serratus) were established. Conodont faunas from the shelf edge and upper slope derived clasts
contain elements of North Atlantic and Midcontinent aspect as well as endemic and cosmopolitan species. They range in age from late Canadian (Fauna D) to basal Whiterock (Fauna 1) of the North American Series and through the British Arenig Series (Paroistodus proteus Zone to earliest ?Eoplacognathus
suecicus Zone of Baltoscandia). Five different biofacies were found, beginning with the oldest Paroistodus- Drepanoistodus Biofacies, followed by the slightly younger Prioniodus-Texania Biofacies; both were found in clasts from Bed 10. Bed 12 yielded clasts with the older Oepikodus-Periodon
Biofacies and the younger Periodon-Texania Biofacies. Bed 14 clasts contained the Periodon-Parapanderodus Biofacies. The shelf break and upper slope environment was characterized by a distinct faunal realm whose composition was controlled by changes in the adjacent habitats of shelf and lower
slope.
Melville Island's salt-based fold belt, Arctic Canada

Melville Island extends across the Cambrian through Devonian Arctic Platform and Franklinian Mobile Belt, and unconformable post-Devonian cover of the Sverdrup Basin. A revised geological map and seismic profiles provide insight into bedrock geology to depths
exceeding 20 km. Possible Precambrian basement is identified at the deepest levels, as are three Proterozoic(?) seismic successions deformed and eroded prior to the Early(?) Cambrian. Cover includes a Cambrian(?) through Devonian shelf-margin wedge that increases in thickness northward to a maximum
exceeding 10 000 m. The overlying Devonian clastic wedge (3000�4600 m) represents the depositional record of the ancestral Ellesmerian Orogeny, southerly directed deformation that eventually produced the exposed salt-based fold belt and terminated lower Paleozoic sedimentation. The fold belt is
continuous downward with a bivergent, thrust-faulted interval with up to 15 per cent shortening, and a basal detachment at 5 km. Long-lived deep-seated thrusts and other faults terminate below the sub-salt décollement and lie within large anticlinoria near the present margin of the Sverdrup
Basin. Ellesmerian deformation continues to the west where style is apparently related to slip on a mid(?)-Cambrian detachment. Six additional Devonian and younger phases of deformation are recognized.
Commodities of economic interest on Melville Island include natural gas, oil sand deposits, coal, showings of copper, lead and zinc sulphides, native sulphur, phosphorite and extensive subsurface rock salt.
Biostratigraphy and systematics of Upper Carboniferous cerioid rugose corals, Ellesmere Island, Arctic Canada
Authors: Bamber E W , Fedorowski J
Published: December 2015

The rugose coral genera Petalaxis and Cystolonsdaleia occur at several stratigraphic levels in Moscovian to Gzhelian strata of the Sverdrup Basin. They are found in shelf carbonates of the middle and upper Canyon Fiord, lower Nansen and lower Belcher Channel
formations, and in correlative debris flow deposits and shallow water, reef-associated carbonates within the basinal Hare Fiord Formation. Lower to Upper Moscovian [Kashirian-lower(?) Podolskian] species include: Petalaxis crassicolumnus sp. nov., P. donbassicus Fomichev, P. ellesmerensis sp. nov.,
P. mcoyanus; (Milne Edwards and Haime), P. multilamellatus sp. nov., P. sp., and Cystolonsdaleia sp. Upper Moscovian (Podolskian-Myachkovian) strata have yielded the new species P. beauchampi, P. thorsteinssoni and C. arctica. These are succeeded by the Kasimovian species P. baculatus sp. nov. and
P. parvus sp. nov., and the Kasimovian or lower Gzhelian species P. sp. cf. P. elyensis (Wilson and Langenheim), C. carteri sp. nov. and C. sp. aff. C. carteri.
Petalaxis and Cystolonsdaleia have a broad geographic range in the Carboniferous of Europe, North America, Asia and North Africa. Several of the Ellesmere Island species are closely comparable to or identical with, corals of similar age from Spain (Cantabrian Mountains), Ukraine (Donets Basin),
Russia (Moscow Basin and the northern Ural Mountains), Spitsbergen and western U.S.A. (Nevada and California).
Skeletal features characterizing both Petalaxis and Cystolonsdaleia include four-layered corallite walls, biform tabularia, a variable, transeptal dissepimentarium, and variable axial structures containing median and lateral lamellae (new term) that originate as thickened, adaxial extensions of the
cardinal septum. Cystolonsdaleia is further distinguished by the addition to its axial structure of short series of axial tabellae, accompanied by periaxial cones (new term) incorporating elongated axial tabellae and elevated, vertically extended axial parts of tabulae.
Geology of the Keskarrah Bay area, District of Mackenzie, Northwest Territories
Authors: Henderson J B
Published: December 2015

The Archean rocks of the area divide naturally into two domains representing contrasting structural levels, separated by a major ductile shear zone. The western domain consists mainly of granitoid rocks with large enclaves of complex orthogneisses representing
the oldest rocks in the area. The eastern domain is dominated by Yellowknife Supergroup supracrustal rocks. A thick basal sequence of pillowed and massive mafic volcanic rocks with minor, intermediate volcanic units mantles a high- level synvolcanic granite. Greywacke-mudstone turbidites of largely
granitoid provenance, containing varied proportions of iron carbonate-, oxide-, and silicate- dominated iron-formation, conformably overlie the mafic volcanic rocks. A small volcanic centre of felsic to intermediate composition within the turbidites is considered contemporaneous with them.
Unconformably overlying most of these rocks is a package of conglomerate, shallow-water sandstone, and turbidites representing a fan delta complex formed in response to early movement on what was to become the major ductile shear zone that separates the two domains. An extended record of
deformation includes events recorded in the orthogneisses that predate deposition of the Yellowknife Supergroup, a folding event involving the older members of the Yellowknife Supergroup, and a subsequent polyphase deformational history involving all parts of the Yellowknife Supergroup. Three
periods of metamorphism include the older, pre-Yellowknife Supergroup evolution of the orthogneisses, the prominent, late Archean, low- pressure series, lower-greenschist to upper-amphibolite metamorphism, and a low-grade Paleoproterozic metamorphism. Economic mineral occurrences include gold
associated with iron-formation and minor base-metal showings associated with mafic volcanic rocks.
Upper Jurassic (Oxfordian-Volgian) Foraminifera from the Husky Formation, Aklavik Range, District of Mackenzie, Northwest Territories
Authors: Hedinger A S
Published: December 2015

The Husky Formation on the western margin of the Beaufort-Mackenzie Basin consists of a predominantly argillaceous clastic succession ranging in age from Late Jurassic (Oxfordian) to Early Cretaceous (basal Berriasian). A section of the lower member at Martin
Creek in the Aklavik Range of the northern Richardson Mountains yielded an unusually rich and well preserved microfauna consisting of 143 species belonging to 49 genera (29 agglutinated and 20 calcareous) of foraminifers. Of these, 55 taxa are new or redefined. One new genus (Saturnella) is
proposed. The microfauna has a markedly Boreal aspect and is most closely comparable to coeval assemblages in the eastern Sverdrup Basin (Canadian Arctic Archipelago), western Siberia, and Svalbard.
Article Commentary: The Influence of Early Infant-Feeding Practices on the Intestinal Microbiome and Body Composition in Infants
Authors: O'Sullivan Aifric , Farver Marie , Smilowitz Jennifer T.
Published: December 2015

Despite many years of widespread international recommendations to support exclusive breastfeeding for the first six months of life, common hospital feeding and birthing practices do not coincide with the necessary steps to support exclusive breastfeeding. These common hospital practices can lead to the infant receiving formula in the first weeks of life despite mothers’ dedication to exclusively breastfeed. Consequently, these practices play a role in the alarmingly high rate of formula-feeding worldwide. Formula-feeding has been shown to alter the infant gut microbiome in favor of proinflammatory taxa and increase gut permeability and bacterial load. Furthermore, several studies have found that formula-feeding increases the risk of obesity in later childhood. While research has demonstrated differences in the intestinal microbiome and body growth between exclusively breast versus formula-fed infants, very little is known about the effects of introducing formula to breastfed infants either briefly or long term on these outcomes. Understanding the relationships between mixed-feeding practices and infant health outcomes is complicated by the lack of clarity in the definition of mixed-feeding as well as the terminology used to describe this type of feeding in the literature. In this commentary, we highlight the need for hospitals to embrace the 10 steps of the Baby Friendly Hospital Initiative developed by UNICEF and the WHO for successful breastfeeding. We present a paucity of studies that have focused on the effects of introducing formula to breastfed infants on the gut microbiome, gut health, growth, and body composition. We make the case for the need to conduct well-designed studies on mixed-feeding before we can truly answer the question: how does brief or long-term use of formula influence the health benefits of exclusive breastfeeding?
Real zeros of holomorphic Hecke cusp forms and sieving short intervals
Authors: Matomäki Kaisa
Published: December 2015

We study so-called real zeros of holomorphic Hecke cusp forms, that is, zeros on three geodesic segments on which the cusp form (or a multiple of it) takes real values. Ghosh and Sarnak, who were the first to study this problem, showed the existence of many such zeros if many short intervals contain numbers whose prime factors all belong to a certain subset of the primes.We prove new results concerning this sieving problem which leads to improved lower bounds for the number of real zeros.
The geometry of dented pentagram maps
Authors: Khesin Boris , Soloviev Fedor
Published: December 2015

We propose a new family of natural generalizations of the pentagram map from 2D to higher dimensions and prove their integrability on generic twisted and closed polygons. In dimension

d

there are

d–1

such generalizations called dented pentagram maps, and we describe their geometry, continuous limit, and Lax representations with a spectral parameter. We prove algebraic-geometric integrability of the dented pentagram maps in the 3D case and compare the dimensions of invariant tori for the dented maps with those for the higher pentagram maps constructed with the help of short diagonal hyperplanes. When restricted to corrugated polygons, the dented pentagram maps coincide with one another and with the corresponding corrugated pentagram map. Finally, we prove integrability for a variety of pentagram maps for generic and partially corrugated polygons in higher dimensions.
Quinto Curcio ante sus fuentes: el episodio de Alejandro y los escitas del Tanais
Authors: Ballesteros Pastor Luis
Published: December 2015

Quinto Curcio encontró en sus fuentes un discurso en el que un escita censuraba a Alejandro, seguido de la réplica del rey. Curcio resumió drásticamente este segundo discurso para dar realce a la crítica al macedonio. Las palabras del escita tienen un sorprendente lenguaje retórico y ciertas alusiones tomadas de la literatura griega, además de posibles referencias indirectas a Calígula. Curcio dice seguir fielmente a su fuente para justificar estas incongruencias pero también para solapar las manipulaciones que él ha realizado con el fin de conseguir sus propios fines narrativos.
Antiguas comunidades judías en Macedonia, Tracia y Épiro Superior
Authors: Ovadiah Asher
Published: December 2015

Evidencias de carácter literario, epigráfico y arqueológico-arquitectónicas, atestiguan la existencia de comunidades judías en Macedonia, Tracia y Épiro Superior (hoy Albania) durante los períodos romano y bizantino temprano. Los Hechos de los Apostoles mencionan la presencia de comunidades judías, y sus sinagogas, en Filipos, Tesalónica y Verroia, en Macedonia. El descubrimiento de inscripciones griegas en Bizya (Tracia), en Tesalónica y Dión, y en la antigua sinagoga de Stobia, sugieren que dichas comunidades preservaron su independencia religiosa y gozaron de un seguro estatus social, económico y cultural. Una antigua tumba judía encontrada en Tesalónica, decorada con una menorah, la sinagoga de Claudius Tiberius Polycharmos en Stobia y la de Saranda (Épiro Superior), añaden pruebas arqueológico- arquitectónicas a las fuentes literarias. A pesar de que las fuentes literarias, los datos epigráficos y los hallazgos arqueológicos son relativamente escasos, parece que en estas regiones, y en otras de la Península Balcánica, existieron también otras comunidades judías.
Le “brigand lusitanien” reconsidéré. Analyse du problème de la terre chez Appien
Authors: Baray Luc
Published: December 2015

L’étude du “brigandage lusitanien” a donné lieu à une importante activité de recherche depuis la fin du XIXe siècle. Pour autant, et malgré une inflexion progressive de l’historiographie moderne vers une approche plus nuancée de l’origine du phénomène, le problème de la terre reste encore aujourd’hui au centre des préoccupations de nombre d’historiens et archéologiques. À partir d’une discussion serrée des principaux passages de Tite-Live, Diodore et surtout Appien, relatifs à la relation que d’aucuns ont voulu établir entre manque et/ou pauvreté de la terre et développement du brigandage chez les Lusitaniens, il est proposé une critique de l’interprétation socio-économique.
Εl voto de un soldado a Silvano – Zeus "Dalbenus"?
Authors: Perea Yébenes Sabino
Published: December 2015

Estudiamos una pieza inédita de una colección privada de Barcelona. Es una escultura votiva, ofrecida por un soldado. Representa al dios Silvano, si bien el nombre de este dios no aparece citado en la inscripción griega de la base, donde se indica que el voto va dirigido a Zeus Dalbenus. Este epíteto Dalbenos / Dalbenus es un hápax. Ofrecemos una lectura del texto e intentamos dar una respuesta a las “incongruencias” entre imagen y texto inscrito.
Ética do mediador social: questões críticas sobre a objectividade e a neutralidade
Authors: Pinto Albuquerque Cristina
Published: December 2015

A dimensão ética da mediação social e comunitária, quer numa ótica micro, quer numa abordagem macro constituir-se-á como o enfoque central do presente artigo. A compreensão dos eixos estru-turantes da relação, nomeadamente a objetivação de uma alteridade fundadora, bem como o debate crítico em torno da (im)possibilidade e/ou adequabilidade ético-moral da neutralidade do mediador, servirão de esteio analítico para a reflexão. Assim sendo, pretende-se que o debate se estruture em torno da complexidade e da reflexividade, inerentes ao processo e conteúdos da mediação e ao decorrente projeto éticoprofissional dos mediadores sociais, como sujeitos de desenvolvimento, justiça social e cidadania.
Impact of Organizational Commitment on Intention to Quit Among Psychaitric Nurses: Evidence from Pakistan
Authors: Yasmin Kashifa , Marzuki Prof. Dr. Najib Ahmad
Published: December 2015

Shortage of the nurses is an important issue in the developing and developed countries. The aim of this paper is to determine the impact of organizational commitment on intention to quit among psychiatric nurses. Based on the model of casual turnover this study assessed the direct effect of organizational commitment on nurse’s intention to quit. The cross sectional data was collected from three hundred five nurses of psychiatric hospitals in Punjab, Pakistan. Structural equation modeling was applied to achieve the objectives. The results revealed that affective commitment and normative commitment have significant impact while continuous commitment has not significant effect on nurse’s intention to quit.  So, the commitment of nurse to hospital goals, missions, and values is not enough to predict her intention to quit from job in the hospital. This study recommends that, the government and policy makers should look beyond forces in their internal and external environment, when considering how to reduce employee’s turnover intentions. This study recommends that future researchers should examine the impact of work environment on intention to quit though burnout as a unit variable. This study contributes socially and economically.
