The circumglobal deep-sea gelatinous giant octopod, Haliphron atlanticus, reaches 4 m in length and uses both benthic and pelagic habitats in the upper 3000 m of the ocean during different life history stages, but it is rarely observed due to the deep-depths where it typically lives. It has been collected in trawls and observed a few times near continental margins or islands and has been identified in the stomach contents of deep-diving predators such as sperm whales and blue sharks or detected as body fragments after predation events. An individual H. atlanticus (~1 m in total length) was video-recorded at 12:21 for about 3 minutes in front of the Shinkai 6500 submersible at 586–599 m (6.5°C, salinity 34.4) along the West Mariana Ridge. It made no escape attempt as the submersible approached and it moved slowly up or down in front of the submersible. It was over the outer seamount-slope (bottom depth ~3208 m) ~50 km west of seamounts (≥1529 m summits), but how it fits into the mesopelagic food web along the ridge is unclear. More information is needed to understand the role of H. atlanticus in oceanic food webs and if it typically lives along seamount ridges.

Abstract The Alpine and Corsican Schistes lustrés (SL) are nearly azoic Jurassic-Cretaceous metasediments often associated with ophiolites. They are derived from both the vanished Valais (N-Penninic) and Piemont-Ligurian (S-Penninic) oceans and from their continental margins. Their age is generally poorly known. Because of fossils discovered by Alb. Heim and by S. Franchi at the beginning of the 20th century, they were believed for a long time to be mostly Liassic in age. We know now that the major part of the SL is Cretaceous. Deep-sea sediments, and particularly the SL, are made up of a hemipelagic-pelagic background (HPB) associated with detrital components of local or distant origin. The nature of the HPB, mostly conditioned by Tethyan and worldwide events, is of great help as an at least rough stratigraphic marker ; in contrast, detrital material is not a reliable marker because it may occur at different times in different places. The HPB exhibits several successive, 10 to 40 m.y. long episodes which are either predominantly argillaceous (A) or calcareous (C). During the deposition of the Juras-sic-Cretaceous SL, seven episodes can be distinguished : C1, calcareous Liassic ; A1, marly Upper Liassic ; C2, calcareous latest Liassic and early Dogger ; A2, shaly or radiolaritic late Dogger-early Malm ; C3, calcareous late Malm ; A3 shaly or marly early Cretaceous ; C4 calcareous late Cretaceous. They can be recognized, each one by its prevailing lithology, and all together by their succession in order from C1 to C4. Nearly all of these subdivisions are here and there dated by rare fossils, which allow for a rough dating of the numerous azoic SL series. As they exhibit very different lithologies, from pelagic calcareous oozes to Black Shales and various kinds of flysch and other mass flow deposits, the SL cannot be considered as a specific, well-defined facies : they are not characteristic for a particular stage of the geodynamic evolution of the Alps. Finally, a possible influence of worldwide events is suggested. First, the role of the depth of the CCD, governed by early late Jurassic and early late Cretaceous biotic recoveries. Secondly, the correlation with first order eustatic events : transgressions on platforms seem to be roughly coeval with A episodes in the deep sea, regressions with C episodes.

Stomach contents were analysed from 23 cetaceans, including individuals of 12 species from the families Delphinidae, Physeteridae, Kogiidae and Ziphiidae, stranded between 1996 and 2006 in the Canary Islands. Cephalopod mandibles(beaks)were found in 21 stomachs and fish remains(otoliths and jaw bones)appeared in 4 stomachs. Two stomachs contained only eye lenses. Cephalopods eaten by dolphins were mainly from the families Ommastrephidae, Sepiidae and Enoploteuthidae, whereas whales had mainly taken specimens of the oceanic squid families Histiotheutidae and Cranchiidae. Fish remains included a pelagic species(i.e. garfish,Belone belone)in dolphin stomachs and bathypelagic(i.e. black scabbard fish,Aphanopus carbo, lantern fish,Lampadena luminosa)and demersal species(Lophiussp.)in a pygmy sperm whale(Kogia breviceps)stomach. Most of the prey species identified are not of commercial interest but one of the sperm whales(Physeter macrocephalus)contained a fishing hook among the stomach contents. Five(22%)of the cetaceans examined had also plastic debris in their stomachs, with big plastic items being taken by deep diving teuthophagous whales.

The article is devoted to the analysis of the changes in economic and legal context for commercial application of intellectual property created under federal budgetary financing. Special attention is given to the role of the state and to comparison of key elements of mechanisms for commercial application of intellectual property that are currently under implementation in Russia and in the West. A number of practical suggestions are presented aimed at improving government stimuli to commercialization of intellectual property created at budgetary expense.

"Der Beitrag reevaluiert die «dogmatische Funktion», eine soziale Funktion, die mit biologischer und kultureller Reproduktion und folglich der Reproduktion des industriellen Systems zusammenhängt. Indem sie sich auf der Grenze zwischen Anthropologie und Rechtsgeschichte des Westens situiert, nimmt die Studie die psychoanalytische Frage nach der Rolle des Rechts im Verhalten des modernen Menschen erneut in den Blick. </br></br>This article reappraises the dogmatic function, a social function related to biological and cultural reproduction and consequently to the reproduction of the industrial system itself. On the borderline of anthropology and of the history of law – applied to the West – this study takes a new look at the question raised by psychoanalysis concerning the role of law in modern human behaviour.

On a warm summer afternoon in 1561, Calvin’s chief editor donned a heavy stole, thick robes, and a gleaming tiara and proceeded to strut and fret his hour upon the stage in a comedy of his own devising. For little more than a century, Christians in the West had celebrated on August 6th Christ’s Transfiguration as the son of God in shining robes. But on this Sunday in Geneva, the city council, consistory, and an audience fresh from having attended edifying sermons at morning service gathered to applaud the transfiguration of the learned Conrad Badius into the title role of ...

The “Orientalizing period” represents a scholarly designation used to describe the eighth and seventh centuries bce when regions in Greece, Italy, and farther west witnessed a flourishing of arts and cultures attributed to contact with cultural areas to the east—in particular that of the Phoenicians. This chapter surveys Orientalizing as an intellectual and historiographic concept and reconsiders the role of purportedly Phoenician arts within the existing scholarly narratives. The Orientalizing period should be understood as a construct of nineteenth- and twentieth-century scholarship that was structured around a false dichotomy between the Orient (the East) and the West. The designation “Phoenician” has a similarly complex historiographic past rooted in ancient Greek stereotyping that has profoundly shaped modern scholarly interpretations. This chapter argues that the luxury arts most often credited as agents of Orientalization—most prominent among them being carved ivories, decorated metal bowls, and engraved tridacna shells—cannot be exclusively associated with a Phoenician cultural origin, thus calling into question the primacy of the Phoenicians in Orientalizing processes. Each of these types of objects appears to have a much broader production sphere than is indicated by the attribute as Phoenician. In addition, the notion of unidirectional influences flowing from east to west is challenged, and instead concepts of connectivity and networking are proposed as more useful frameworks for approaching the problem of cultural relations during the early part of the first millennium bce.

This study is intended to describe the meaning of the architectural pattern and family relationship among Madurese society. There are three points that will be discussed in this article. The first, the meaning behind Madurese choice in building their home in tanian lanjang. The second, the vital role of kobhung on the pattern of tanian lanjang. The third, the metamorphosis of tanian lanjang: changable and unchangable pattern. To describe all of these aspects and to know what is really meant by Madurese society, it is extremely needed to be part of this society; living with them for a temporal time is a must. The result of this research consists of three important points. The first, the meaning of house building in tanian lanjang is to present the seniority of the inhabitants. The oldest always stays in the west position and the youngest always stay in the east position. A house also becomes a private place for women and kids. Women are also the inhabitants and the owners of houses. The second, kobhung has a vital role in tanian lanjang. It is used to become the centre of all activities done by men. The third, the existence of tongghuh and kobhung is one of unchangable pattern of tanian lanjang.
