This essay reviews the theoretical and empirical literature on quality disclosure and certification. After comparing quality disclosure with other quality assurance mechanisms and describing a brief history of quality disclosure, we address two sets of theoretical issues. First, why don't sellers voluntarily disclose through a process of “unraveling” and, given the lack of unraveling, is it desirable to mandate seller disclosure? Second, when we rely on certifiers to act as the intermediary of quality disclosure, do certifiers necessarily report unbiased and accurate information? We further review empirical evidence on these issues, with a particular focus on healthcare, education, and finance. The empirical review covers quality measurement, the effect of third-party disclosure on consumer choice and seller behavior, as well as the economics of certifiers. (JEL D18, K32, L15, M31)

Experimental Phonetics

The article dedicated to the memory of Ludmila Verbitskaya is concerned with the role of acoustic and perceptual research in the development of Lev Shcherba’s phonological theory. Of fundamental importance for this were the studies of the Laboratory of Experimental Phonetics of Leningrad University, conducted in the 1950–1970s, in which fundamental theoretical issues were inseparable from the problems of application. It is at this period that Verbitskaya’s early works were created, largely responsible for her reputation of an outstanding linguist. In 1965, she defended her Ph.D. dissertation Russian Speech Units vis-à-vis Аllophones and Phonemes (Lev Zinder, advisor), based on an extensive experimental study. Among other things, she challenged the dogma of the traditional phonological theory that speakers perceive only distinctive phonemic oppositions, by demonstrating the ability of the speakers of Russian to distinguish a greater variety of vowels than was normally supposed. It should be noted, however, that in Verbitskaya’s experiment, of all the allophones involved, the informants discerned only those responsible for providing the hardness-softness consonantal opposition. In this case, the informants not only perceived the differences, but were able to interpret them in accordance with the phonological system of the Russian language.

All the desired properties of cement primarily depend on the physicochemical characteristics of clinker from which the cement is produced. The mineralogical composition of the clinker forms the most important parameter influencing these properties.Optical microscopy provides reasonably accurate information pertaining to the thermal history of the clinker, while XRDA still remains the proven method of phase identification, and bulk chemical composition of the clinker can be readily obtained from XRFA. Nevertheless, all these microanalytical techniques are somewhat limited in their applications, and SEM/EDXA combination fills this gap uniquely by virtue of its high resolution imaging capability and possibility of instantaneous chemical analysis of individual phases.Inhomogeneities and impurities in the raw meal, influence of kiln conditions such as sintering and cooling rate being directly related to the microstructure can be effectively determined by SEM/EDXA. In addition, several physical characteristics of cement, such as rhcology, grindability and hydraulicity also depend on the clinker microstructure.

First Time

This given article reveals the topicality not only of destructive, but also of constructive, as well as hybrid conflicts. Practically it has been done for the first time. It also describes the history of the formation of both foreign and domestic social conflictology. At the same time, the chronology of the development of the latter is restored and presented objectively, in full, taking into account the contribution of those researchers who actually stood at its origins. The article deals with the essence of the socio-psychological approach to understanding conflicts. The subject of social conflictology includes the regularities of their occurrence and manifestation at various levels, spheres and conditions, including normal, complicated and extreme ones. Social conflictology includes the theory and practice of diagnosing, resolving, and resolving social conflicts. It analyzes the difficulties that occur in defining the concept, structure, dynamics, and classification of social conflicts. Therefore, it is no accident that the most important task is to create a full-fledged theory of social conflicts. Without this, it is impossible to talk about effective settlement and resolution of social conflicts. Social conflictology is an integral part of conflictology. There is still a lot of work to be done, both in theory and in application, for its complete design. At present, there is an urgent need to develop conflict-related competence not only of professionals, but also for various groups of the population.

This study first approaches the history of the observer’s gaze, that is, as observers, we are forming or constructing our way of visualizing moving images. Secondly, it reaffirms the importance and need of resistance of the teaching / learning of Art as a compulsory curricular component for high school. Finally, the third part reports an experience with video art production in a class of first year high school students, establishing an interrelationship between theory and practice, that is, we study video art content to reach the production of videos, aiming as a final result, the art videos created by the students of the Reference Center in Environmental Education Forest School Prof. Eidorfe Moreira High School. The first and second stages of this research share a theoretical part of the Master ‘s thesis, Making films on the Island: audiovisual production as an escape line in Cotijuba, periphery of Belem, completed in 2013.

This chapter surveys the history of classical Greek drama productions at the Department of Theatre Arts of Tel Aviv University as the basis for an exploration of the issue of theatre and art education. By analysing the students’ approach to classical Greek drama, we can see how they deal with the interpretative reading, translation, and performance of such texts on stage. We also see how the ancient works invite the students to delve more deeply into their distinctive content and forms; to draw links between theory and practice, and between text and context; to gain a deeper understanding of the issues of style and styling; and to engage in a richer experimentation with various aspects of stage performance—such as pronunciation, diction, voice, movement, music, and mise-en-scène.

This study reconstructs the connected history of socio-economic and intellectual practices related to property in seventeenth-century Bengal. From the perspective of socio-economic practices, this study is concerned with the legal transfer of immovable property between individuals. From the perspective of intellectual practice, this study is concerned with how property was understood as an analytical category that stood in a particular relation to an individual. Their connected history is examined by analysing socio-economic practices exemplified in a number of documents detailing the sale and donation of land and then situating these practices within the scholarly analysis of property undertaken by authors within the discipline of nyāya—the Sanskrit discipline dealing primarily with ontology and epistemology. In the first section of the essay, I undertake a detailed examination of available land documents in order to highlight particular conceptions of property. In the second section of the essay, I draw out theoretical issues examined in nyāya texts that relate directly to the concepts expressed in the land documents. In the third and final section of the essay, I discuss the shared language and shared concepts between the documents and nyāya texts. This last section also addresses how the nyāya analysis of property facilitates a better understanding of claims in the documents and what nyāya authors may have been doing in writing about property.

Major Discrepancy

AbstractDuring the 1980s, Julien Jalâl Ed-Dine Weiss, founder of the Al-Kindi ensemble of Aleppo, invented a qānūn in just intonation with which he attempted to solve a major discrepancy between the theory and practice of maqām-scales. Weiss objected to the introduction of Western standards, observing that they distort the significance of interval ratios and prevent a comparative understanding of the modal system as a transnational phenomenon. In the twentieth century, the implementation of equal-semitone temperament emerged simultaneously with a notable invasion of sociological criteria into musical inquiry. The polarity observed between westernisation and tradition can be seen most visibly in the present search for identity amongst Middle- and Near-Eastern musicians, but this schismogenic process can also be observed in the history of the Western avant-garde, where microtonal explorations have been halted in favour of extra-musical conceptuality. While cross-cultural musicians are faced with a new climate of distrust, it seems most likely that the principles that draw us apart may originate in the very patterns of thought in which our notion of culture operates. Weiss's tuning system may serve as a helpful tool to foster a new and universal epistemology of tone, bridging and transcending the apparent contradictions between the two spheres.

Abstract Over two decades ago, Korpi and Palme (1998) published one of the most influential papers in the history of social policy discipline, in which they put forward a “paradox of redistribution”: the more countries target welfare resources exclusively at the poor, the less redistribution is actually achieved and the less income inequality and poverty are reduced. The current paper provides a state-of-the-art review of empirical research into that paradox. More specifically, we break down the paradox into seven core assumptions, which together form a causal chain running from institutional design to redistributive outcomes. For each causal assumption, we offer a comprehensive and critical review of the relevant empirical literature, also including a broader range of studies that do not aim to address Korpi and Palme’s paradox per se, but are nevertheless informative about it.
