This junior/senior level text is devoted to a study of first-order logic and its role in the foundations of mathematics: What is a proof? How can a proof be justified? To what extent can a proof be made a purely mechanical procedure? How much faith can we have in a proof that is so complex that no one can follow it through in a lifetime? The first substantial answers to these questions have only been obtained in this century. The most (...) striking results are contained in Goedel's work: First, it is possible to give a simple set of rules that suffice to carry out all mathematical proofs; but, second, these rules are necessarily incomplete - it is impossible, for example, to prove all true statements of arithmetic. The book begins with an introduction to first-order logic, Goedel's theorem, and model theory. A second part covers extensions of first-order logic and limitations of the formal methods. The book covers several advanced topics, not commonly treated in introductory texts, such as Trachtenbrot's undecidability theorem. Fraissé's elementary equivalence, and Lindstroem's theorem on the maximality of first-order logic. (shrink)

The debate about the differing philosophies of human-nature relationship is ongoing. Several studies discuss the need to develop and adopt a new environmental paradigm to replace the neoclassical economic paradigm predominant in Western societies. This issue has been discussed mainly at a societal level. Society or societies are, however, entities that consist of smaller particles. If a phenomenon is supposed to exist in an entity, signs of the phenomenon should also be found in its particles, business enterprises among others. This (...) paper examines a shift of a managerial paradigm in a business organization, since not only the actions of individuals and governments but also those of business enterprises account for the preservation of the natural environment. It studies empirically how a managerial paradigm can shift from “traditional managerial thinking” to ”environment-related management.” Two frameworks will be developed for this purpose. (shrink)

This article argues that previous research on the outcomes of corporate responsibility should be refined in two ways. First, although there is abundant research that addresses the link between corporate responsibility (CR) and financial performance, hardly any studies scrutinize whether the type of corporate responsibility makes a difference to this link. Second, while the majority of CR research conducted within business studies concentrates on the financial outcomes for the firm, the societal outcomes of CR are left largely unexplored. To tackle (...) these two deficiencies, this article extends the different conceptualizations of corporate responsibility and elaborates both the financial and the societal outcomes of different types of CR.

In Thomas Thomson's System of chemistry of 1802 Bergman and Scheele are actually considered as creators of the analytical concept of an element. With regard to this, a detailed investigation of the work of Bergman and Scheele shows that Thomson's statement contains mistakes as well as inadmissable simplifications and generalizations. It is correct, however, that Bergman in 1774–1777 specifically anticipated in essential aspects the analytical element concept proposed by Lavoisier in 1787–1789.

This is one of the most important books on quantum mechanics ever written for lay readers, in which an eminent physicist and successful science writer, Heinz Pagels, discusses and explains the core concepts of physics without resorting to complicated mathematics.

Der auf Kants kritischer Philosophie fußenden Philosophengeneration galt Herder als hoffnungslos anachronistischer, vorkritischer Philosoph, dessen Denken für das eigene philosophische Programm keine Relevanz zukomme. Das im folgenden dokumentierte Projekt geht demgegenüber von der Hypothese aus, daß Herder in die Vorgeschichte der Philosophie des deutschen Idealismus gehört, daß er Vorläufer und Weggenosse der nachkantischen Philosophengeneration war. Der vorliegende Band versammelt Arbeiten, die zur Begründung und Diskussion dieser Auffassung in unterschiedlicher Weise beitragen: es geht um die Konturierung der für diese Thematik relevanten (...) Aspekte von Herders eigenem Denken, um die Erschließung der gemeinsamen philosophischen und wissenschaftshistorischen Grundlagen des Herderschen Denkens und der Philosophie des deutschen Idealismus, nicht zuletzt geht es um die Erarbeitung der Rezeption von Herders Philosophie in der nachkantischen Philosophengeneration.

This article employs the concept of affective assemblage to discuss how fertility travelers make sense of their decision to travel to Spain for oöcyte donation. Motherhood is brought into being through racialized and gendered discourses on ova exchange; idealized and feminized Spanish donor bodies. In their accounts, fertility travelers employ a narrative in which oöcytes become necessary spare parts, yet also, exotic substances with temperament and racialized nationality as well as collective bodies – shaped by the recipient woman’s body, intent, (...) and desire. In this manner, kinship is created through shared blood and space, desire and intent while differences between recipients and donors are minimized. The directionality of desire, hope, and imagination has the effect of naturalizing transnational egg donation and transforming it into a shared western European femininity of sorts. (shrink)

Introduction: Emotional fluctuations and mood swings are common among adults with Attention Deficit/Hyperactivity Disorder. Here we investigated if these problems could be retrospectively traced back to childhood behavior.Methods: Adults with an ADHD diagnosis and a population-based control sample completed the Adult ADHD Self-report Scale, the Wender Utah Rating Scale and the Mood Disorder Questionnaire. All participants also provided self-reported information about co-existent psychiatric and somatic diseases, and demographic data. Reports on the MDQ were used to define subgroups with [MDQ] and (...) without [MDQ] life-time periods of emotional fluctuations and the WURS scale was used to retrospectively assess childhood ADHD related behaviors and symptoms.Results: 50.2% of the ADHD group and 5% of the controls were defined with emotional fluctuations [MDQ]. Childhood behavior ratings of “impulsivity,” “loosing of control,” and “trouble with authorities” independently predicted emotional fluctuations reported in adulthood via logistic regression analyses. Inclusion of these three items in a classification analysis gave an accuracy score around 70% in identifying each of the two MDQ categories in the ADHD group.Discussion: The strong association between self-reported features of emotional problems in childhood and in adulthood suggests a trajectory that should be detected and remediated at an early age. Future longitudinal studies should prioritize the examination of developmental mechanisms explaining the persistence of emotional problems from childhood into adulthood. (shrink)

Mario Bunge is an important philosopher of science. But he does not limit himself to using his “truth-technology” in his particular philosophical discipline. For decades, he has also endeavored to achieve an independent profile as a public intellectual on the basis of his wide-ranging competence. To this end, he authoritatively criticizes authors who market themselves to the public as anti-scientists or as pseudo-scientists. On his home continent of Latin America, Mario Bunge is regarded as a role model because he has (...) achieved international recognition like no other South American philosopher before him. (shrink)
