Classical Perception

AbstractAn assessment is given as to the extent to which pure unitary evolution, as distinct from environmental decohering interaction, can provide the transition necessary for an observer to perceive quantum dynamics as classical. This has implications for the interpretation of quantum wavefunctions as a characteristic of ensembles or of single particles and the related question of wavefunction “collapse”. A brief historical overview is presented as well as recent emphasis on the role of the semi-classical “imaging theorem” in describing quantum to classical unitary evolution.

Small Metal Particles

The evolution of microstructures of 10- to 100-Å diameter particles of Rh and Pt on SiO2 and Al2O3 following treatment in reducing, oxidizing, and reacting conditions have been characterized by TEM. We are able to transfer particles repeatedly between microscope and a reactor furnace so that the structural evolution of single particles can be examined following treatments in gases at atmospheric pressure. We are especially interested in the role of Ce additives on noble metals such as Pt and Rh. These systems are crucial in the automotive catalytic converter, and rare earths can significantly modify catalytic properties in many reactions. In particular, we are concerned with the oxidation state of Ce and its role in formation of mixed oxides with metals or with the support. For this we employ EELS in TEM, a technique uniquely suited to detect chemical shifts with ∼30Å resolution.

Materialist Interpretation

The denial of the existence of contradiction is at the root of all idealism in epistemology and the cause for alienations.  This alienation has become a hindrance for the understanding of the nature and the historical evolution mathematics itself and its role as an instrument in the enquiry of the physical universe (1). A dialectical materialist approach incorporating  the role of the contradiction of the unity of the opposites, chance and necessity etc., can provide a proper understanding of the historical evolution of mathematics and  may ameliorate  the negative effect of the alienation in modern theoretical physics and cosmology. The dialectical view also offers a more plausible materialist interpretation of the bewildering wave-particle duality in quantum dynamics (2).

Sociocultural Systems

Although psychologists typically see creativity as an individual-level event, sociologists and cultural anthropologists are more likely to view it as a sociocultural phenomenon. This phenomenon takes place at the level of relatively large and enduring collectives, such as cultures, nations, and even whole civilizations. This chapter reviews the extensive research on such macro-level creativity. The review begins with a historical overview before turning to the cross-sectional research on the creative Ortgeist, a subject that encompasses the factors that influence the relative creativity of both preliterate cultures and entire modern nations. From there the chapter turns to role of the Zeitgeist in affecting the creativity of civilizations across time—the rise and fall of creative activity. This research examines both quantitative and qualitative causes that operate both short- and long-term.

History And Theory

This article argues for the importance of Bible translations through its historical achievements and theoretical frames of reference. The missionary expansion of Christianity owes its very being to translations. The early Christian communities knew the Bible through the LXX translations while churches today still continue to use various translations. Translations shape Scripture interpretations, especially when a given interpretation depends on a particular translation. A particular interpretation can also influence a given translation. The article shows how translation theories have been developed to clarify and how the transaction source-target is culturally handled. The articles discuss some of these “theoretical frames”, namely the functional equivalence, relevance, literary functional equivalence and intercultural mediation. By means of a historical overview and a reflection on Bible translation theories the article aims to focus on the role of Africa in translation history.

The Relationship

This chapter provides a historical overview of ambivalent encounters between Indonesia and the Arab world through findings that show the relationship between Indonesia and the Middle East. It recounts the Indonesians' earliest encounters with Arab traders in the seventh century, from confrontations with Indo Persian Sufi up to the current democratization process that have been marked by contradictory dynamics. It also explains how Arabs have been acknowledged as teachers of Islam and allies in the postcolonial nonbloc movement. The chapter describes the gloomy counterimage of the Arab world against which Indonesian officials and religious leaders drew the picture of a tolerant, pluralist Indonesian Islam. It mentions the key role of the mobility across the Indian Ocean in the formation of Islamic culture in Indonesia.

The Eu

The discussion thus far has focused on centralized and shared administration as ways in which EU policy is delivered. This chapter focuses on Comitology and the making of secondary norms, which normally take the form of rules. This cuts across the previous analysis, in the sense that rulemaking is a feature of both direct and shared administration. The structure of the discussion is as follows. It begins with analysis of the problem presented by rulemaking, and the necessity for any polity, including the EU, to administer an area through secondary norms of a legislative nature. This is followed by an historical overview of rulemaking in the EU and the role of Comitology therein. The focus then shifts to detailed evaluation of the approach to rulemaking in the Lisbon Treaty.

The Relationship

This chapter examines the relationship between democratization and the economy. It first provides an historical overview of the emergence of capitalist democracy before discussing some general problems of the relationship between democracy and capitalism, highlighting the main areas in which the two systems condition each other. It then considers the role of business in democratizing countries, and more specifically the role of business actors in the transition to democracy. It also explores the intricacies of combining major political and economic reforms. Some key points are emphasized; for example, capitalism focuses on property rights while democracy focuses on personal rights. Furthermore, capitalism produces inequality, which can both stimulate and hamper democratization.
