During May-October 2007, soil and root samples from 539 fields were collected from 11 monsoon rice varieties in 12 regions in Myanmar. All regions surveyed and 90% of fields sampled were infested with the rice root nematode Hirschmanniella oryzae. The average H. oryzae population was 10/100 mL soil and 419/20 g roots respectively. In 6.9% of the fields sampled 50 H. oryzae/g root were found. The average root population densities were the highest (640/20 g roots) in Taungpyan variety and the (...) lowest (155/20 g roots) in Immayebaw variety. The lowest soil and the second-lowest root populations of H. oryzae were observed in Shwethweyin which may indicate that this rice variety is less susceptible to H. oryzae. Among three cropping sequences, the highest frequency of occurrence (94%) was found in the rice-rice cropping sequence. Based on the prominence value (a combination of the frequency of occurrence and abundance) of H. oryzae, Hlaingtharyar was the most infested region where susceptible rice varieties are grown and rice-rice cropping sequence is practiced. The rice production in this region may be the most at risk of suffering important yield losses due to H. oryzae. (shrink)

In this paper, we devise a network that consists of argumentation schemes and critical questions that participants in debates can use to easily construct arguments that attack or support former arguments. As a prototype, we build a potential network of argumentation schemes and critical questions with a practical reasoning scheme at its center. The usefulness of a NASCQ in constructing and reconstructing complex arguments and in formal argumentation is also explored along with argumentation more broadly.

It is often necessary and reasonable to justify preferences before reasoning from them. Moreover, justifying a preference ordering is reduced to justifying the criterion that produces the ordering. This paper builds on the well-known ASPIC+ formalism to develop a model that integrates justifying qualitative preferences with reasoning from the justified preferences. We first introduce a notion of preference criterion in order to model the way in which preferences are justified by an argumentation framework. We also adapt the notion of argumentation (...) theory to build a sequence of argumentation frameworks, in which an argumentation framework justifies preferences that are to underlie the next framework. That is, in our formalism, preferences become not only an input of an argumentation framework, but also an output of it. This kind of input-output process can be applied in the further steps of argumentation. We also explore some interesting properties of our formalism. (shrink)

The aim of this paper is to critically review the traditional typology of argument macrostructures, particularly, the dichotomy between linked and convergent structure. We have found an argument structure that does not fall under one of those five traditional categories: basic, serial, divergent, linked and convergent. We show that the new argument structure, which we call the recursive structure, is not rare-earth, but ubiquitous in real argumentation. Then, we propose and justify a new approach to diagramming arguments of the structure. (...) The new argument structure is really new because arguments of the new structure are analyzed and evaluated differently from those of the other structures, especially from hybrid arguments considered in the literature. In light of the new argument structure, we present a hypothesis why assumptions and exceptions of a defeasible argument play different roles in dialectical settings. (shrink)

What signals do firms in emerging economies send to stakeholders when they adopt corporate social responsibility practices? We argue that in emerging economies, firms that adopt CSR practices positively signal investors that their firms have superior capabilities for filling institutional voids. From an institution-based view, we hypothesize that the institutional environment moderates the signaling effect of CSR on a firm’s financial performance. Based on a sample of firms from ten Asian emerging economies, we find a positive relationship between CSR practices (...) and financial performance. This positive relationship is stronger in the less developed capital market than in the more developed one. The financial benefits of CSR practices are also more salient in the low information diffusion market than in the high one. We emphasize that signaling theory and the institution-based view can jointly contribute to the CSR literature. (shrink)

Pylyshyn's effort in establishing the cognitive impenetrability of early vision is welcome. However, his view about the role of attention in early vision seems to be oversimplified. The allocation of focal attention manifests its effect among multiple stages in the early vision system, it is not just confined to the input and the output levels.

An inclusive vision of mathematics-- its beauty, its humanity, and its power to build virtues that help us all flourish. For mathematician Francis Su, a society without mathematical affection is like a city without museums. To miss out on mathematics is to live without experiencing some of humanity's most beautiful ideas. In this profound book, written for a diverse audience but especially for those disenchanted by their past experiences, an award-winning mathematician and educator weaves personal reflections, puzzles, and stories to (...) show how mathematics meets basic human desires and cultivates virtues essential for human flourishing. Readers will explore mathematical concepts-- and see how mathematical thinking can even fulfill such longings as for love, play, freedom, justice, and community. Some lessons come from those who have struggled, including philosopher Simone Weil, whose own mathematical contributions were overshadowed by her brother's, and Christopher Jackson, who discovered mathematics as an inmate in a federal prison. Christopher Jackson's letters to the author appear throughout the book and show how this intellectual pursuit can-- and must-- be open to all. (shrink)

This paper documents that business ethics has positive impacts upon the development of intellectual capital. Knowledge has become the most important asset of modern businesses, and this study argues that business ethics is associated with the development of intangible knowledge resources—intellectual capital. Businesses with ethical values at the core reinforce ethical conducts and successfully build trust with their various stakeholders, leading to the formation of an ethical and trustworthy corporate culture and a positive corporate environment. Thus, in this reasoning, an (...) ethical approach to business can encourage open communication, problems solving, knowledge sharing and creativity among employees to increase organisational capital; enhance interactions and relationships with suppliers, customers and other stakeholders to increase social capital; attract and retain good talent to increase human capital. Questionnaire survey is adopted as the research method with businesses in the electronic and information technology industries in Taiwan as sample. The results suggest that business ethics is associated with increased intellectual capital. Thus, this study demonstrates that the development of intellectual capital is in line with strengthened ethics. It contributes to the literature through combining research on business ethics with intellectual capital theories and extends the extant intellectual capital literature. (shrink)

Jaina philosophical treatise with a Sanskrit commentary of Hemacandra Sūri, 12th cent.

Dieses Buch verteidigt die These, dass bis auf leicht ausgrenzbare Ausnahmen die Ersetzung von Synonyma in einem Satz die Wahrheit oder Falschheit des Satzes nicht beeinflusst. Maik Sühr liefert eine sorgsame Formulierung der These, indem er sie aus dem im Allgemeinen akzeptierten Prinzip der Kompositionalität ableitet. Er konfrontiert sie im Anschluss mit zum Teil noch weithin unbekannten augenscheinlichen Gegenbeispielen und macht eine Reihe von neuen Vorschlägen, um diese zu entkräften. In diesem Zusammenhang setzt sich Sühr mit verschiedenen Themen innerhalb der (...) Sprachphilosophie und der Philosophie des Geistes auseinander. So bespricht er u.a. Freges Sinnhierarchie, kognitive Äquivalenz sowie verschiedene Aspekte der Semantik von Allquantifikationen und weil-Sätzen. Ferner nimmt er mit neuen Argumenten Stellung zur Debatte zwischen Externalisten und Internalisten in Bezug auf mentalen Gehalt und plädiert für eine grundsätzliche Unterscheidung zwischen semantischen und mentalen Gehalt. Im Schlussteil wendet er die Ersetzbarkeits-These auf das sogenannte Paradox der Analyse an. Im Zuge seiner kritischen Diskussion verschiedener Theorien über Begriffsanalysen entwickelt er dabei seine eigene Konzeption von Analysen als Erklärungen. (shrink)

Le problème de l’identité personnelle est une préoccupation essentielle des philosophes modernes depuis que la conscience est mise en scène philosophiquement. Cependant parmi eux il n’y en a pas beaucoup qui considèrent la mémoire comme le fondement de l’identité humaine, bien qu’aujourd’hui, et grâce aux neurosciences, on sache pourtant qu’elle joue un rôle capital. D’une manière générale, les empiristes s’y intéressent davantage que les rationnalistes. Ceux‐ci ayant comme idéal normatif les systèmes mathématiques ne pensent pas qu’elle puisse contribuer à élargir (...) nos connaissances du monde. C’est ce qui explique que le système des idées claires et distinctes chez Descartes, s’établit directement par la conscience présente. De son côté, l’empiriste sceptique Hume, bien qu’il ait souligné l’importance de la mémoire dans notre personnalité, n’a pas pu mettre en pleine lumière sa nature et son fonctionnement. L’esprit considéré comme l’ensemble des perceptions et des idées est loin de constituer l’identité de l’homme normal. On voit dans les théoriesbergsoniennes de la durée et de la mémoire une toute autre perspective qui fonde l’identité personnelle sur l’équilibre mental de la conscience présente et de l’inconscient, c’est‐à‐dire du moi superficiel et du moi profond.
