    Accretion onto Black Holes and Neutron Stars: Differences and Similarities

    Full text link
    Accreting black holes and neutron stars at luminosities above 0.01 of the critical Eddington luminosity have a lot of similarities, but also drastic differences in their radiation and power density spectra. The efficiency of energy release due to accretion onto a rotating neutron star usually is higher than in the case of a black hole. The theory of the spreading layer on the surface of an accreting neutron star is discussed. It predicts the appearance of two bright belts equidistant from the equator. This layer is unstable and its radiation flux must vary with high frequencies.Comment: 12 pages, 10 figures, invited talk, to appear in Proc. of ESO Workshop Held in Garching 6-8 Sept. 1999 in Honour of Riaccardo Giacconi (Springer, eds.

    Building on the system of reason provided for by the Greek philosopher and specifically Aristotle, St. Thomas Aquinas built a comprehensive system and theory of natural law which has lasted through the ages. The theory was further developed in the Middle Ages and in the Enlightenment Ages by many a prominent philosopher and economist and has been recognized in the Modern Age. The natural law-theory and system has been repeatedly applied to the spheres of economic thought and has produced many lasting contributions such as private property rights and individual rights. In recent times with the collapses of the financial system and rapid globalization, there has been a renewed interest in the application of natural law theory to economics to counter a certain anthropology and distortion of values created by a modern economic system of selfpreservation deriving its insights from the philosophies of Thomas Hobbes and Niccolo Machiavell

    E-commerce technology adoption framework by New Zealand small to medium size enterprises

    This paper attempts to highlight a framework for the adoption of electronic commerce (EC) technologies in New Zealand with specific interest in the small to medium-size enterprise (SME) sector of the economy. The main thrust of the research was to develop the framework for EC adoption by the New Zealand SMEs and hence study the accelerators and impediments to the adoption and diffusion of EC technologies. The paper shows how IS/IT adoption and diffusion theories and practicalities can be explored for developing the proposed EC adoption framework. It is argued that results from research case studies based on the framework are able to identify the factors influencing and leading to the adoption of e-commerce technologies by the New Zealand SMEs

    The purpose of this paper is to provide insights into how the proliferation of globalization has impacted labor markets both in a advanced industrialized nations and well as developing nations. Insightful analysis will be drawn from Oatley (2011) on division of labor, Jaumotte & Tytell (2007) on labor compensation, Hahn & Narjoko (2013) on the impact on South Asian Countries, Basu (2016) on wage as a share of GDP and Wallace, Gauchat & Fullerton (2011) on the impact of globalization and labor markets on inequality

    The purpose of this paper is to provide an analysis of the discipline of political economy, international political economy and their respective historical developments. The paper will then focus on globalization and evaluate the strength and weaknesses of the policy to globalize. Further analysis will be conducted to show the importance of the topic of globalization as it relates to public finance. Rosen & Gayer (2014), Sackery, Schneider & Knoedler (2016), Marlin-Bennett (2017), Ravenhill (2008) and Weingast & Witman (2006) will provide insights into the development of the discipline and its modus operendi. The historical development of the discipline will be provided for by Ingram (1915) and the aforementioned authors will also provide insights into the weakness and strengths of the policy to globalize. Garett & Mitchell (2001) and Kumar (2006) will provide additional insights into the importance of globalization as it pertains to public finance
