De go Ivvár. Som om det var Iver Jåks
No full textDenne artikkelen tar utgangspunkt i en samling objekter som hovedsakelig ble samlet inn av den samiske kunstneren
Iver Jåks (1932–2007). Nordnorsk Kunstmuseum har som eier av disse objektene definert dem som ett verk i museets
samling og gjennom museets kuratoriske praksiser, til tross for at kunstneren ikke selv har satt de sammen eller tilvirket alle delene. Artikkelforfatteren fikk selv i oppdrag av museet å installere det angivelige kunstverket og inngår
dermed i de museale prosessene. Gjennom egen involvering skriver forfatteren frem museumsobjektets proveniens
og viser hvor komplekst kunstverk og museumssamlinger kan være.
This article takes a collection of objects by the Sámi artist Iver Jåks (1932–2007), owned by the Art Museum of Northern Norway, as a starting point. Although not all the objects are made by the artist, and he himself has not put
these parts together into a separate work of art, they have nevertheless been defined as an art piece by the museum’s
collection and through the museum’s curatorial practices. The author of the article was herself commissioned by
the museum to install the alleged work of art and is thus part of the museums processes. Through her own involvement, the author investigates these objects’ provenance and displays how complex works of art and museum collections can be
Drawing Sovereignty: The Museum Work of Sámi Artist Ánddir Ivvár Ivvár/Iver Jåks
No full textFrom the first part of the 1950s until the mid-1980s, the Sámi artist Ánddir Ivvár Ivvár/Iver Jåks (1932–2007) played an influential role in the making of exhibitions displaying Sámi culture and art, both in a Norwegian and Sámi museum context. This article examines Jåks museum work with a specific focus on his drawings of Sámi objects from museum collections, duodji in Northern Sámi. The author argues that Jåks’ methodological application of drawing contributed to the development of a visual imagery deeply rooted in a Sámi way of thinking, seeing, and doing. Consequently, the article shows that Jåks’ museum work can be read as an act of doing sovereignty through the act of drawing
Laser Powder Bed Fusion of ODS 14YWT from Gas Atomization Reaction Synthesis Precursor Powders
No full textLaser powder bed fusion (LPBF) additive manufacturing (AM) is a promising route for the fabrication of oxide dispersion strengthened (ODS) steels. In this study, 14YWT ferritic steel powders were produced by gas atomization reaction synthesis (GARS). The rapid solidification resulted in the formation of stable, Y-containing intermetallic Y2Fe17 on the interior of the powder and a stable Cr-rich oxide surface. The GARS powders were consolidated with LPBF. Process parameter maps identified a stable process window resulting in a relative density of 99.8%. Transmission electron microscopy and high-energy x-ray diffraction demonstrated that during LPBF, the stable phases in the powder dissociated in the liquid melt pool and reacted to form a high density (1.7 × 1020/m3) of homogeneously distributed Ti2Y2O7 pyrochlore dispersoids ranging from 17 to 57 nm. The use of GARS powder bypasses the mechanical alloying step typically required to produce ODS feedstock. Preliminary mechanical tests demonstrated an ultimate tensile and yield strength of 474 MPa and 312 MPa, respectively.This article is published as Saptarshi, Sourabh, Matthew DeJong, Christopher Rock, Iver Anderson, Ralph Napolitano, Jennifer Forrester, Saul Lapidus, Djamel Kaoumi, and Timothy Horn.

Development of Methodologies for the Analysis of the Efficiency of Flood Reduction Measures in the Rhine Basin on the Basis of Reference Floods
No full textAfter some years of extreme flooding in the 1990s extended efforts were made to improve flood protection by means of an integrated river basin management. Part of this strategy is the implementation of decentralised flood reduction measures (FRM). With this in mind, the CHR/IRMA-SPONGE Project DEFLOOD was initiated. By establishing a set of methodological tools this project aims at making a step further towards a quantitative hydrological evaluation of the effects of local FRM on flood generation in large river basins. The basin of the River Mosel and in particular, the basin of its tributary Saar served as case study area for testing the methodological approach. A framework for an integrated r iver basin modelling approach (FIRM \u96 Flood Reduction) based on generation of hydrometeorological reference conditions, precipitation-runoff modelling and flood routing procedures was set up. In this approach interfaces to incorporate the results of scenario calculations by meso-scale hydrological modelling are defined in order to study the downstream propagation of the effect of decentralised flood reduction measures including the potential retention along minor rivers in large rivers. Examples for scenario calculations are given. Based on the experience gained the strategy for the use of the methodological framework within the context of river basin management practice are identified. The application of the methodology requires a set of actions which has to be installed in the Rhine/Meuse basins. The recommendations suggest that - beside progress in hydrological modelling - a base of knowledge needs to be built up and administered which encompasses hydrologically relevant information on the actual state and prospected developments in the River Rhine basin. Furthermore, problem-oriented hydrological process studies in selected small scale river basins ought to be carried out. Based on these studies conceptual meso-scale modelling approaches can be improved and validated in terms of reducing the uncertainty factor, which is inherent in all scenario calculations.Irma-Spong
Viscosity-induced crossing of the phantom divide in the dark cosmic fluid
No full textChoosing various natural forms for the equation-of-state parameter w and the bulk viscosity ζ, we discuss how it is possible for a dark energy fluid to slide from the quintessence region across the divide w = −1 into the phantom region, and thus into a Big Rip future singularity. Different analytic forms for ζ, as powers of the scalar expansion, are suggested and compared with experiments.© 2013 Brevik.

Covariant Quantum Electrodynamics in Terms of a Possible Ether Flow
No full textThis paper from 1971 has a special history. At that time the present author was working with the covariant quantization procedure for an electromagnetic field in a dielectric medium. In such a theory, the commutator for the potentials contains the medium's four-velocity Vµ. What appeared to be a natural idea, was to suggest that Vµ is not only a formal remedy (as in the Gupta-Bleuler theory), but that it reflects a concept of deeper physical significance, namely the four-velocity of the all-pervading ether. The idea was actually related to that put forward by Dirac in 1951-1953, although there in a somewhat different context. This proposal was written up in a paper published in the archival series "Theoretical Physics Seminar in Trondheim", No. 4, 1971. Submitting afterwards the paper to Il Nuovo Cimento, I received a report from a referee stating that all mention of an ether was pure nonsense, far outside of any reasonable physics. So I gave the idea up at that time. Some years have however elapsed since then, and as we know the ether concept is at present often used in theoretical physics, commonly called the Einstein-Dirac ether. I was probably far ahead of my time. I am posting an extract of this old paper on the arXiv now, since I was recently recommended to do so. A link to the original paper is given
El cambio social
No full textThe concept of social change refers to alterations and modifications in the social behavior and the cultural values of determinated social systems and structures. In opposition to the so called social progress, social change has no teologic meaning. Social system means a structure of social processes and relations showing some regularity. The dichotomy between social statics (structures) and social dynamics (change) is therefore incorrect, because the first does not exist in reality. Cultural changes are but functions of the social changes. Among the functions which are contributions of a social system to the fundamental needs of its members to a more inclusive social system, the author distinguishes actual functions, latent or not evident functions and disfunctions (of negative effect). With regard to causation, the author points out MAV IVER\u27s classification into distributive, collective and conjunctural phenomena. To forecast and control socio-cultural phenomena, a scientific methods is necessary. After pointing out the conditions for a correct scientific methodology, the author explains the modern complementary and qualitative trends: typology, the same combined with psychology and cultural anthropology and the "functional process", which reduces social change to a manageable analytical process. Finally, he examines five basic aspects of the social change process: social deviations, innovations, the innovation valuating process the transition phase and the institutionalization processThe concept of social change refers to alterations and modifications in the social behavior and the cultural values of determinated social systems and structures.

Man in his native noblesse? : chivalry and the politics of the nobility in the tragedies of George Chapman
No full textIn this thesis I argue that the three plays under consideration - Bussy
D'Anbois, The Conspiracy and Tragedy of Charles Duke of Byron, and The
Revenge of Bussy D'Ambois - illustrate Chapman's concern with the role of
chivalry in England following the debacle of the Essex Rebel lion in 1601.
My contention is that, for Chapman, the Essex Rebellion exposed the
fragility and the inconsistencies of Elizabethan chivalry and the political
threat represented by its preoccupation with martial values.
I suggest that in his plays, Chapman sets out to deconstruct the myth
of chivalry by exposing it as a romantic concept which is used by the
martial nobility as a means of Emphasizing their political rights. The
values of chivalry - prowess, honour, loyalty, generosity, courtesy and
independence - are shown, by the plays, to be incompatible with the
political ambitions of the nobility. By associating themselves with this
mythical concept of chivalry, political figures cane to identify their
factions with the values of chivalry. Chapman, I argue, shows haw the myth
is established and then exposes it for what it is, by portraying his
characters as unable to live up to their expected mythical ideals.
Chivalry is stripped of its mythical trappings and exposed as militaristic,
aggressive and politically motivated.
The thesis is divided into five chapters. In the first, I consider
Chapman alongside the Tacitean historians who were connected with the Essex
circle in the 1590s and show how, in The Conspiracy and Tragedy of Charles
Duke of Byron, the dramatist transformed the providentialist narrative of
his source into a play with Tacitean connotations, emphasizing the
relationship between chivalry and constitutional political theory. In the
second chapter I consider Chapman's interest in chivalry and discuss
generally the romantic concept of Elizabethan chivalry and its relationship
with the political concerns of the nobility. In Chapters Three to Five I
discuss Chapman's portrayal of chivalry and its political impliications
Ethical Dilemmas and Paradoxes in Assurance Practice: A New Approach that Acknowledges Compromise, Trust and Relationality
No full textAssurance of corporate sustainability reports relies on the idea of a third-party assuror who is independent and objective. The assurance approaches typically used by accountancy companies have been developed over many years and are supported by internal as well as external standards. With the help of these standards, the assuror provides credibility to the public statements of the companies through a thorough checking of statements, data and supporting systems. However, the orthodox approach overlooks or neglects the many paradoxes and dilemmas that are the daily experience of most assurors, e.g. what it means to be independent and objective while at the same time trying to develop a relation with the client. There has also been criticism of assurance, as currently practiced, as being too rigid, too predictable and providing too few benefits to the companies assured. In this thesis, the author explores why and how his own assurance practice differs from the more orthodox approach. This has led to the description of an alternative approach to assurance, called the ‘artist’ approach that takes the ethical dilemmas and paradoxes into account. The approach has been developed and described on the basis of the author’s own experiences using a critically reflexive methodology. The methodology builds on personal narratives and iterative feedback from fellow researchers and supervisors. The development of the ‘artist’ approach is based on: 1) a critical investigation into the idea of ‘compromise’, which leads to an alternative way of thinking about the practice of assurance; 2) a critical investigation into notions of trust and distrust, and power relations, and the effect of these on assurance work; and 3) a concept of ‘stumbling together’, which is built on relationality and ‘essential references’, where the assuror and the assuree are mutually exploring the territory. In the ‘artist’ approach, the values of independence and objectivity are compromised. The assuror actively strives to build personal trust based (at least in part) on technical kinship. Through this trust the power dynamics of the ‘insider’ and the ‘outsider’ are contained; indeed, the notion of ‘insider/outsider’ is forgotten in the moment. Independence has turned into interdependence, and objectivity into mutual engagement, where both assuror and assuree together might discover new issues not known to either of them before. In the orthodox approach, the assuree is ‘called to account’, whilst in the artist approach, the assuree is invited to ‘give an account’. This process of collaborative exploration allows the potential for radical new discoveries, for both assuror and assuree. The ‘artist’ approach as described here has affinities with complex responsive processes of relating as explained by Stacey. In the ‘artist’ approach, the craftsman approach is always paradoxically present at the same time, and the approach makes use of the same tools and the same framework as the craftsman approach. A wider understanding and application of the ‘artist’ approach can potentially lead to significant changes in the way assurors act, and hopefully to assurance results that are more relevant and useful
