Mer än bara konstnär? : Att närma sig en triangelkomposition i begrepp, förutsättning och realitet / More than just an artist? : To approach a triangle composition in concept, precondition and reality.

Björsson, Kerstin January 2008 (has links)
Syftet är att granska relationen mellan konstnären och marknaden. Flertalet frågor behandlas, såsom om konsten och konstnärer står inför ett paradigmskifte, varför det är fult att säga konst och pengar i samma mening och vad verksamma konstnärer tycker om situationen. Uppsatsen redogör för begreppet konstnär ur ett historisk och sociologiskt perspektiv. Förutsättningar för konstnären gås igenom med fokus på kulturpolitiken från 1974 tills idag, och marknaden. Fyra konstnärer har intervjuats för att skapa en bild av den realiteten som de verkar i, hur de ser på konstnärskapet och den bästa av världar. / The purpose is to study the relationship between the artist and the market. Several questions are dealt with, such as does art and artists stand before a paradigm shift, why's it a bad thing to mention art and money together and what do the working artist think about the situation. The thesis deals with concept of the artist from a historical and sociological point of view. Preconditions for artists are clarified with a focus on cultural policies from 1974 and onwards. Four artists have been interviewed to create a picture of the working reality, what they think about their artistry and what the best of worlds look like.

Fracture Resistance of Non-metallic Molar Crowns Manufactured with CEREC 3D

Madani, Dalia 06 April 2010 (has links)
Objectives: To compare fracture strength and fatigue resistance of ceramic (ProCAD, Ivoclar-Vivadent)(C) and resin composite (Paradigm MZ100, 3M/ ESPE)(R) crowns made with CEREC-3D. Methods: A prepared ivorine molar tooth was duplicated to produce 40 identical prepared specimens made of epoxy resin (Viade). Twenty (C) crowns and 20 (R) were cemented to their dies using resin cement. Ten of each group were subjected to compressive loading to fracture. The remaining 10 of each group were subjected to mechanical cyclic loading for 500,000 cycles. The survivors were subjected to compressive loading to fracture. Results: No significant difference in mean fracture load was found between the two materials. However, only 30% of the (C) crowns vs. 100% of the (R) crowns survived the cyclic loading test. Conclusions: (R) crowns demonstrated higher fatigue Resistance than (C) crowns in-vitro and might better resist cracking in-vivo.

Responses of bird communities inhabiting boreal plain riparian habitats to forestry and fire

Kardynal, Kevin John 31 October 2007
Worldwide, riparian areas are considered among the most biologically productive and species-rich habitats on the landscape and provide important breeding areas for many bird species. In the Boreal Plain ecozone of western Canada, forests adjacent to riparian areas are generally protected from forest harvesting through the retention of treed buffer strips. <p>Riparian buffer strips are expected to provide habitat for wildlife including many passerine bird species. Recently, non-conventional methods of riparian management have been implemented in parts of the Boreal Plain with the intent of aligning forestry more closely with natural disturbance processes. How bird communities associated with these management scenarios diverge from natural disturbances and how riparian birds interact with disturbances in the adjacent upland habitat are key questions in the conservation of boreal riparian bird communities. To answer these questions, I surveyed birds inhabiting riparian areas with adjacent naturally disturbed (burned) and harvested forest to determine how bird communities differ early (1-5 years) post-disturbance and, separately, in a before-and-after harvesting study. <p>Riparian species associated with burned merchantable shoreline forests and riparian areas included Common Yellowthroat (<i>Geothlypis trichas</i>) and Eastern Kingbird (<i>Tyrannus tyrannus</i>). Le Contes Sparrow (<i>Ammodramus leconteii</i>) was associated with burned riparian habitats adjacent to non-merchantable forests (e.g., bog, fen), while Alder Flycatcher (<i>Empidonax alnorum</i>) and Wilsons Warbler (<i>Wilsonia pusilla</i>) were indicative of harvested sites with larger buffers (30 m). Riparian species richness was highest in burned non-merchantable sites. Multivariate Redundancy Analysis of post-disturbance bird communities showed greater divergence in overall (riparian and upland) community composition than one with only riparian species. This suggests reduced sensitivity of riparian birds to disturbances in forested areas compared to upland bird communities. However, a higher natural range of variability was exhibited in riparian bird community composition in post-fire sites than in post-harvested sites. This emphasizes that forest management practices do not currently fully approximate natural disturbance for boreal riparian birds. <p>To assess the response of bird communities in riparian habitats to forestry, I studied bird communities one year (2004) prior to forest harvest and two years (2005 and 2006) after harvest. One of three treatments, 1) 5-35% retention (0 m buffer), 2) 35-75% retention (10 m buffer with variable retention in the next 30 m), 3) 75-100% retention (50 m buffer) and unharvested reference sites, was randomly assigned to 34 wetlands. Treatments were designed to represent buffer management strategies currently applied in the Boreal Plain. Eight of 22 species showed a significant response (p<0.1) to treatment, year or year*treatment effects including two riparian species, the Common Yellowthroat and Song Sparrow (<i>Melospiza melodia</i>) that increased in abundance in harvested sites. Overall pre-disturbance communities diverged (p<0.05) over the three-year study period as shown using Multiple-response Permutation Procedures (MRPP). However, riparian bird communities did not diverge from pre-disturbance or from reference sites providing further evidence that riparian bird communities are less impacted by forestry in the adjacent upland habitats than overall bird communities. Therefore, alternative forest harvesting methods should be explored that encompass landscape-scale management including total buffer removal to maximize conservation objectives for boreal forest bird communities while attempting to maintain natural disturbance processes.

A Description of the Natural Place of Magic in Philosophy and Religious Studies

Williams, Damien P 22 April 2008 (has links)
The concept of magic is most often considered as a foil by scholars in the fields of philosophy and religious studies, or it is discussed as part of the investigation of “primitive” systems of belief and ritual. In this essay, magic is investigated as a system of inquiry and explanation unto itself, connected to but distinct from both philosophy and religious studies, and an argument is presented for understanding systems of magic as both natural and rational outgrowths of a particular perspective on reality.

Open innovation : What to open? What to close?

Mooyoung, Son, Dan, Zou January 2011 (has links)
Business management Paradigm is Changing. We used to have big, best, and fast and now it seems that we are having one more paradigm of “Open”. Chesbrough (2003) argued for cooperating between competitors or allies in his article “The era of open innovation”. (ChesbroughH.W, 2003) This research is about open innovation with customer participation. Many organizations built platform to motivate customers to participate the product development process. Hence, we selected three different types of platforms which are full-open, semi-open and closed platform for case study. To compare different perspective from organizations and customers, we will use both of case study of the organizations who opened competencies to the customers and survey of the customers who are creating derivative products. From that case-study and survey result, we aim to figure out what to open and what to close for the organizations that are implementing open innovation strategy. We will suggest a competency pyramid model that helps organizations to divide their competencies into two different sectors: open competency and closed competency. And finally, we will find out what factors are important to make a platform successful.

Urban Shrinkage in Liepāja : Awareness of population decline in the planning process

Kaugurs, Kristaps January 2011 (has links)
The aim of the study is to investigate the current state of awareness of urban shrinkage inLiepājaby the key actors involved in the planning process. Last couple of hundred years have brought many transformations in urbanity that was always accompanied by the growth of the population and expansion of the city. However, the new patterns of urban development emerged in the last decades all over the globe, causing cities to lose the inhabitants resulting in urban shrinkage.Liepāja, the third largest city inLatvia, has lost a quarter of its population in last two decades and the trend continues. The long-term municipal planning document is being presented during this research in a light of which the research question is asked: “What is the current state of awareness of urban shrinkage inLiepājaby the key actors?” Utilising Flyvbjerg’s phronetic form of inquiry in combination with case study and repeated semi-structured interviews, the dominant planning views related to urban shrinkage are sought and analysed. The research identifies three underlying causalities that shape the decisions in planning and leave formidable consequences for the future of the city. The causalities identified and discussed in this paper are (1) the planning legacy; (2) the misconception; and (3) the political sensitivity of the urban shrinkage.

Samspelet mellan finansiella rådgivare och kunder

Hansson, Sofia, Lövquist, Joanna January 2011 (has links)
Background: Previous studies focused on customer loyalty and customer satisfaction. But no studies focused on the interaction between the financial advisor and their client. Therefore we have chosen to focus on this knowledge gap.Purpose: The purpose of this thesis is to illustrate how the interaction between financial advisors and customers affect financial advisory in investment decision making.Method: The thesis philosophy was positivistic because patterns were found with help of a survey. Furthermore is the paper quantitative since the thesis is measurable and it try to explain the interaction between the financial advisors and the clients demographic characteristics and how it influence the financial advice Conclusion: The theories thin-slicing and similarity attraction paradigm may not apply to the interaction between financial advisor and client. / Bakgrund:  Tidigare studier fokuserar på kundnöjdhet och kundlojalitet. Däremot saknas studier kring samspelet mellan finansiell rådgivare och kund. Därför har vi valt att fokusera på denna kunskapslucka Syfte: Syftet med uppsatsen är att belysa hur samspelet mellan finansiella rådgivare och kunder påverkar den finansiella rådgivningen vid ett investeringsbeslut. Metod: Uppsatsen har positivistisk undersökningsfilosofi då mönster hittades med hjälp av en undersökning. Vidare är uppsatsen kvantitativ eftersom den är mätbar och att den har undersökt om det finns några samband mellan den finansiella rådgivarens och kundens demografiska egenskaper samt om dessa påverkar rådgivningen. Slutsats: Teorierna thin-slicing och similarity attraction paradigm kan inte tillämpas i samspelet mellan finansiella rådgivare och kunder.

Swedish FDI in Africa : Locational determinants of FDI from the perspective of the OLI paradigm

Hellqvist, Christian, Boman, Martin January 2012 (has links)
The global flows of foreign direct investment (FDI) to Africa have increased steadily in recent years but the research on what determines the location of these investments is scarce. Research focusing on FDI flows from small and open economies such as Sweden is even more uncommon. From the locational factors found in the OLI paradigm we developed a model that was tested on a dataset of 25 African countries over the period of 2007 to 2010. The model proved inadequate in explaining the African inward FDI flows from Sweden. However, it well explains the aggregated inward FDI flows from firms around the world to Africa. Our results implies that the locational determinants derived from the OLI paradigm are inadequate in explaining Swedish FDI flows to Africa and maybe even in explaining flows from a small and open economy to developing countries. The answer to the question of what locational determinants are important for Swedish companies investing in African countries should perhaps be sought for elsewhere.

Foreign Direct Investment In Africa : A Look Into FDI Determinants

Indopu, Kufamuyeke, Tagne Talla, Joseph January 2010 (has links)
Foreign Direct Investment is seen as a critical source of capital inflow and a stimulant of economic growth in many developing nations. It brings with it benefits such as job creation, technology and knowledge transfers just to mention a few. Thus many African countries are keen in finding ways of attracting FDI. The main objective of this paper is to empirically examine the determinants of foreign direct investment (FDI) by incorporating an econometric method based on cross-sectional data from 41 African countries over the period 2002-2007. More precisely, this research intends to answer the following question: what are the relevant determinants that promote FDI inflows in Africa? Among the several determinants of FDI, the finding suggests that market size and natural resource predominance are the main determinants of FDI into Africa.
