This article uses a well-defined setting to suggest an optimistic view about the distributional effects of immigration. Section 2 provides a general picture of the native-immigrant differences in labour force participation, unemployment, and occupational and educational attainment, taking skill levels and years since immigration into account. Section 3 investigates the inequality impact of immigration by summarizing the potential labour market impacts and the wage and employment consequences. Section 4 deals with the potentially slow integration of immigrants into the labour market (...) of the host country, as well as with the role that self-selection and selection through politically set admission rules can play for the performance in the labour market. It also considers cultural or ethnic identity as an independent factor potentially affecting economic success and discusses the consequences for inequality. Section 5 concludes. (shrink)

Foundations of Dialectical Psychology is a compilation of the writings of Klaus F. Riegel on dialectical psychology. The book presents chapters discussing such topics as the dialectics of human development; history of dialectical psychology; temporal organization of dialogues; and the analysis of the concept of crisis and its underlying philosophical model and ideology. Psychologists and students will find the book invaluable.

Vor dem Hintergrund einer weitreichenden Neuorientierung, die der praktischen Vernunft in der Methodologie , in der Sprachphilosophie und in der strukturalen Wissenschaftstheorie den Primat einräumt, werden die Aporien rationalistischdezisionistischer Konzeptionen deutlicher sichtbar. In diesem Papier wird der argumentative Ursprung von Feyerabends Kritik an Rationalität und Wissenschaft als auf einer - angesichts der 'praktischen Wende' der neueren Wissenschaftsphilosophie - überholten Wissenschaftsauffassung basierend analysiert. Feyerabends Zurückweisung der Wissenschaft erscheint dann weder als Konsequenz seiner Vernunftkritik noch als Bruch in seiner Argumentation; er vollstreckt (...) vielmehr die Gegenstandsverfehlung der methodologistischen Wissenschaftstheorie unverdeckt.

In many countries consumers have shown an increasing interest to the way in which food products are being produced. This study investigates Chinese consumers’ attitudes towards different pig production systems by means of a conjoint analysis. While there has been a range of studies on Western consumers’ attitudes to various forms of food production, little is known about the level of Chinese consumers’ attitudes. A cross-sectional survey was carried out with 472 participants in 6 Chinese cities. Results indicate that Chinese (...) consumers prefer industrial pig production systems, where traditional pig breeds are raised, over large-scale and small family farms. Farms with maximum attention to food safety, which furthermore can provide lean meat with consistent quality, are also preferred. Imported pig breeds and tasty but variable meat were rejected. A 3-cluster solution found that consumers from cluster 1 focus almost exclusively on the food safety aspect. Consumers from cluster 2 show weak overall attitudes to pig production systems in general. Cluster 3 stands out by being very positive about industrial, large-size farms and consistent quality. From a Chinese consumer’s perspective, the industrial approach seems to represent values such as achievement and evolution, as well as quality and safety, since pig production is moving away from low-cost, low-quality, and low-safety family-scale systems. A complex set of rural and environmental development, quality aspects, and food safety measures are challenges that must be met by the stakeholders of pig production systems in China. (shrink)

This 1999 volume takes a critical look at the current divide over immigration policies. It hopes to shed light on the debate by bringing together papers that investigate the link between trade and factor mobility, particularly labour migration, from theoretical and empirical perspectives. It examines the substitutability between trade and migration, the impact of regional integration on the location of economic activity, the role of public goods provisions, and the political economy of migration. Several papers quantify the link between trade, (...) trade policies, migration and income distribution in sending and receiving nations using econometric methods and general equilibrium simulations. Case studies of past and present migration episodes are also presented: the impact of NAFTA on migratory pressure and wage gaps; the trade-migration links between Eastern and Western Europe; and the historical experience with migration flows in the nineteenth century.

The aim of this thematically unified anthology is to track the history of epistemic logic, to consider some important applications of these logics of knowledge and belief in a variety of fields, and finally to discuss future directions of research with particular emphasis on 'active agenthood' and multi-modal systems. It is accessible to researchers and graduate students in philosophy, computer science, game theory, economics and related disciplines utilizing the means and methods of epistemic logic.

hiS volume in the Synthese Library Series is the result of a conference T held at the University of Roskilde, Denmark, October 31st-November 1st, 1997. The aim was to provide a forum within which philosophers, math ematicians, logicians and historians of mathematics could exchange ideas pertaining to the historical and philosophical development of proof theory. Hence the conference was called Proof Theory: History and Philosophical Significance. To quote from the conference abstract: Proof theory was developed as part of Hilberts Programme. (...) According to Hilberts Programme one could provide mathematics with a firm and se cure foundation by formalizing all of mathematics and subsequently prove consistency of these formal systems by finitistic means. Hence proof theory was developed as a formal tool through which this goal should be fulfilled. It is well known that Hilbert's Programme in its original form was unfeasible mainly due to Gtldel's incompleteness theorems. Additionally it proved impossible to formalize all of mathematics and impossible to even prove the consistency of relatively simple formalized fragments of mathematics by finitistic methods. In spite of these problems, Gentzen showed that by extending Hilbert's proof theory it would be possible to prove the consistency of interesting formal systems, perhaps not by finitis tic methods but still by methods of minimal strength. This generalization of Hilbert's original programme has fueled modern proof theory which is a rich part of mathematical logic with many significant implications for the philosophy of mathematics.

This book sheds light on some recent discussions of the problems in probability theory and their history, analysing their philosophical and mathematical significance, and the role pf mathematical probability theory in other sciences.

In this volume specialists of medieval music and philosophy put the medieval 'musica' into the context of ideas and institutions in which it existed. The significance of 'musica' cannot be understood from a modern point of view since 'music' does not match the medieval 'musica'.

F. Rapp behauptet, daß die Methodologie der Falsifikation von allgemeinen Theorien faktisch einen Induktionsschluß voraussetzt und daher methodologische Symmetrie zwischen Verifikation und Falsifikation besteht. Rapps Argumentation beruht jedoch auf einer unhaltbaren Annahme über methodologische Prinzipien und forschungspraktisches Vorgehen.

Die von F. Rapp propagierte "starke Falsifikation" ist weder ein vertretbares noch ein in den empirischen Wissenschaften übliches Verfahren. Die gängigsten Verfahren zur Theorienmodifikation sind sogar mit der "starken Falsifikation" logisch unverträglich. Außerdem ist die "starke Falsifikation" häufig deshalb nicht anwendbar, weil wir bereits Instanzen kennen, welche die durch die "starke Falsifikation" zu erzielende Hypothese falsifizieren würden. Die "starke Falsifikation" schreibt ferner in manchen Fällen die Rückkehr zu bereits falsifizierten Hypothesen vor. Rapps Annahme, die Möglichkeit der wissenschaftlichen Prognose sei davon (...) abhängig, ob man das Verfahren der "starken Falsifikation" akzeptiert oder nicht, ist unhaltbar. (shrink)

There are reasons to endorse Krueger & Funder's (K&F's) critique, but also to disagree with their diagnosis. A “problem-seeking approach” is hardly the cause of imbalance and lack of theoretical integration. Precommitted, ideological theories afford a more appropriate explanation.

In this paper which consists of two parts (Teil I and Teil II) we champion Diophantus of Alexandria and Isabella BaÅ¡makova against Norbert Schappacher. In two publications ([Schappacher 1998a] and [Schappacher 1998b]) he puts forward inter alia two propositions: Questioning Diophantus’ originality he considers affirmatively the possibility that the Arithmetica are the joint work of a team of authors like Bourbaki. And he calls BaÅ¡makova’s claim (in [BaÅ¡makova 1972]) that Diophantus uses negative numbers, a nonsense , reproaching her for her (...) thoughtlessness . Teil I: First, we disprove Schappacher’s Bourbaki thesis. Second, we investigate the semantic meaning and historical significance of Diophantus’ keywords $ λvarepsilon tildeιψιζ and ὕπαρξιζ. Next, we discuss Schappacher’s epistemology of the history of mathematics and defend BaÅ¡makova’s methods. Finally we analyse in detail three problems from Diophantus’ Arithmetica (and their solutions) given by Thomas Heath and Helmuth Gericke as proof of the their claim that Diophantus did not use negative numbers. Teil II: In this Part, we give 33 places where Diophantus uses negative quantities as intermediate results; they appear as differences a − b of positive rational numbers, the subtrahend b being bigger than the minuend a; they each represent the (negative) basis ( πλvarepsilonυρacuteα ) of a square number ( τvarepsilonτρacuteαγω ν o ζ ), which is afterwards computed by the formula (a - b) 2 = a 2 + b 2 - 2ab $ . Finally, we report how the topic Diophantus and the negative numbers has been dealt with by translators and commentators from Maximus Planudes onwards. Und er kommt zu dem Ergebnis: ≪Nur ein Traum war das Erlebnis. Weil≫, so schlieβt er messerscharf, ≪nicht sein k a n n, was nicht sein d a r f.≫ CHRISTIAN MORGENSTERN: Palmstrm. (shrink)
