Updating Data Semantics

This paper has three main goals. First, to motivate a puzzle about how ignorance-expressing terms like maybe and if interact: they iterate, and when they do they exhibit scopelessness. Second, to argue that there is an ambiguity in our theoretical toolbox, and that exposing that opens the door to a solution to the puzzle. And third, to explore the reach of that solution. Along the way, the paper highlights a number of pleasing properties of two elegant semantic theories, explores some meta-theoretic properties of dynamic notions of meaning, dips its toe into some hazardous waters, and offers characterization theorems for the space of meanings an indicative conditional can have

Radical Leadership in Post-Parojinog Ozamis Politics

The history of Philippine democracy is marked with the persistent existence of oppressive forces that subjugate the people. Oppression and corruption are the two historically rooted characteristics of Philippine politics. One of the many reasons for the proliferation of corruption and oppression is the existence of local warlords who impose their power over the masses. These political warlords immure the people by violence in order for them to remain in power. The oppressive structure of governance designed and imposed by these warlords became the mainstream structure of government. Democracy is no longer intended to secure the development of the people, but for the few who are in power. Ozamis city is not immune from such structural injustice; for decades the city was ruled by a family whose failure in running a democratic state is prevalent in the actual lives of the people in the city. Not until a radical shift of power was realized in the advent of a progressive leadership exhibited by Police Chief Inspector Jovie Espenido. Though his critics may brand his leadership as authoritarian, it will be argued that radical means are necessitated in order to restructure society and to redirect its course towards bettering the lives of the people. Disruption is needed not just to challenge the present state. It is intended to uproot the putrefied structure that has taken roots in the system in order to plant a new. This paper intends to philosophically assess Jovie Espinido’s leadership following Chantal Mouffe’s radical democracy paradigm

Forecasting in the light of Big Data

Predicting the future state of a system has always been a natural motivation for science and practical applications. Such a topic, beyond its obvious technical and societal relevance, is also interesting from a conceptual point of view. This owes to the fact that forecasting lends itself to two equally radical, yet opposite methodologies. A reductionist one, based on the first principles, and the naive inductivist one, based only on data. This latter view has recently gained some attention in response to the availability of unprecedented amounts of data and increasingly sophisticated algorithmic analytic techniques. The purpose of this note is to assess critically the role of big data in reshaping the key aspects of forecasting and in particular the claim that bigger data leads to better predictions. Drawing on the representative example of weather forecasts we argue that this is not generally the case. We conclude by suggesting that a clever and context-dependent compromise between modelling and quantitative analysis stands out as the best forecasting strategy, as anticipated nearly a century ago by Richardson and von Neumann

Problem-Solving Argumentative Patterns in Plenary Debates of the European Parliament

The aim of this paper is to describe the way in which argumentative patterns come into being in plenary debate over legislative issues in the European Parliament. What kind of argumentative patterns are to be expected within this macro context? It is shown that the argumentative patterns that come into being in legislative debate in the European Parliament depend for the most part on the problem-solving argumentation that is put forward in the opening speech by the rapporteur of the parliamentary committee report. This argumentation can be pragmatic problem-solving argumentation or complex problem-solving argumentation. The most important prototypical argumentative patterns are investigated in the argumentation put forward by the Members of parliament. This investigation is based on an inventory of the arguments that can in principle be used to support or attack the initial problem-solving argumentation put forward by the rapporteur

Trialing project-based learning in a new EAP ESP course: A collaborative reflective practice of three college English teachers

Currently in many Chinese universities, the traditional College English course is facing the risk of being ‘marginalized’, replaced or even removed, and many hours previously allocated to the course are now being taken by EAP or ESP. At X University in northern China, a curriculum reform as such is taking place, as a result of which a new course has been created called ‘xue ke’ English. Despite the fact that ‘xue ke’ means subject literally, the course designer has made it clear that subject content is not the target, nor is the course the same as EAP or ESP. This curriculum initiative, while possibly having been justified with a rationale of some kind (e.g. to meet with changing social and/or academic needs of students and/or institutions), this is posing a great challenge for, as well as considerable pressure on, a number of College English teachers who have taught this single course for almost their entire teaching career. In such a context, three teachers formed a peer support group in Semester One this year, to work collaboratively co-tackling the challenge, and they chose Project-Based Learning (PBL) for the new course. This presentation will report on the implementation of this project, including the overall designing, operational procedure, and the teachers’ reflections. Based on discussion, pre-agreement was reached on the purpose and manner of collaboration as offering peer support for more effective teaching and learning and fulfilling and pleasant professional development. A WeChat group was set up as the chief platform for messaging, idea-sharing, and resource-exchanging. Physical meetings were supplementary, with sound agenda but flexible time, and venues. Mosoteach cloud class (lan mo yun ban ke) was established as a tool for virtual learning, employed both in and after class. Discussions were held at the beginning of the semester which determined only brief outlines for PBL implementation and allowed space for everyone to autonomously explore in their own way. Constant further discussions followed, which generated a great deal of opportunities for peer learning and lesson plan modifications. A reflective journal, in a greater or lesser detailed manner, was also kept by each teacher to record the journey of the collaboration. At the end of the semester, it was commonly recognized that, although challenges existed, the collaboration was overall a success and they were all willing to continue with it and endeavor to refine it to be a more professional and productive approach

Historical objections against the number line

Historical studies on the development of mathematical concepts will help mathematics teachers to relate their students’ difficulties in understanding to conceptual problems in the history of mathematics. We argue that one popular tool for teaching about numbers, the number line, may not be fit for early teaching of operations involving negative numbers. Our arguments are drawn from the many discussions on negative numbers during the seventeenth and eighteenth centuries from philosophers and mathematicians such as Arnauld, Leibniz, Wallis, Euler and d’Alembert. Not only does division by negative numbers pose problems for the number line, but even the very idea of quantities smaller than nothing has been challenged. Drawing lessons from the history of mathematics, we argue for the introduction of negative numbers in education within the context of symbolic operations

Computational Visualistics: Dealing with Pictures in Computer Science

Building blocks from many disciplines have to be integrated into a general science of images. Computational visualistics has been formed as a contributing field embracing all aspects of dealing with images computationally. Two basic concepts of computer science are introduced. Applied to the concept "image", they determine the methodological core of computational visualistics. As the contribution of computer science to the subject of image theory, interactive pictures are examined. Finally, relations to other "image sciences" are sketched. * * * Bausteine vieler Disziplinen müssen in eine allgemeine Bildwissenschaft integriert werden. Als Beitrag aus der Informatik versteht sich die Computervisualistik, die alle Aspekte rechnergestützten Umgangs mit Bildern umfaßt. Zwei Grundbegriffe der Informatik werden vorgestellt und bestimmen, auf den Begriff "Bild" angewendet, den methodologischen Kern der Computervisualistik. Als Beitrag der Informatik zum Gegenstand der Bildtheorie werden interaktive Bilder betrachtet. Schließlich werden die Beziehungen zu anderen "Bildwissenschaften" kurz umrissen
