Does belief have an aim?

The hypothesis that belief aims at the truth has been used to explain three features of belief: (1) the fact that correct beliefs are true beliefs, (2) the fact that rational beliefs are supported by the evidence and (3) the fact that we cannot form beliefs `at will. I argue that the truth-aim hypothesis cannot explain any of these facts. In this respect believing differs from guessing since the hypothesis that guessing aims at the truth can explain the three analogous features of guessing. I conclude that, unlike guessing, believing is not purposive in any interesting sense

A simple theory of promising

[FIRST PARAGRAPHS] Why do human beings make and accept promises? What human interest is served by this procedure? Many hold that promising serves what I shall call an information interest, an interest in information about what will happen. And they hold that human beings ought to keep their promises because breaches of promise threaten this interest. On this view human beings take promises seriously because we want correct information about how other human beings are going to act. Some such view is taken for granted by most philosophical accounts of promissory obligation. I agree that human beings do want such information and that they often get it by accepting promises. But I doubt that promising exists because it serves this information interest. I shall argue that promising exists because, at least when it comes to each other’s actions, human beings often have what might be called an authority interest: I often want it to be the case that I, rather than you, have the authority to determine what you do. If you promise me a lift home, this promise gives me the right to require you to drive me home; in that sense, it puts me in authority over you. So much is obvious. What I claim is that human beings often want such authority for its own sake (not just to facilitate prediction or co-ordination). I often have an interest in having the right to determine whether you’ll give me a lift, over and above any interest I have in knowing what you (or we) will actually do. And I claim that promising exists because it serves this authority interest

Traveling Yellow Peril: Race, Gender, and Empire in Japan's English Teaching Industry

Contemporary U.S. white migrants working in Japan long-term as English teachers find themselves in an increasingly precarious labor market. When reacting to industry flexibilization, the U.S. men I interviewed during two years of fieldwork in Nagoya regularly invoked Filipina competition as an impending threat to their livelihoods. Anxieties coalesced around the question of whether racialized postcolonial subjects can fully inhabit the category of "native English teacher." This essay combines Asian American, postcolonial, and transnational American Studies perspectives to situate these "nativist" logics within an historical trajectory of anti-Asian labor backlash in the United States and "benevolent assimilation" policies in the Philippines. These histories reappear within Japan's neoliberal labor regimes to position Filipina migrants as a feminized "yellow peril" menace to hegemonic white masculinities abroad. Extending Homi Bhabha's theories, the essay demonstrates how Filipina "colonial mimicry" undermines the embodied, linguistic authority of white "native" English teachers and becomes a discursive conduit for the transplantation into Japan of the "white male victim" figure commonly seen in domestic U.S. culture wars

Inquiry Teaching: It is Easier than You Think!

This article is a survey of the literature on inquiry teaching. Many teachers do not participate in inquiry teaching for various reasons. The following are the main reasons: it takes too much time; students do not learn what they need for the state test; and, the teachers do not know how to grade projects and presentations. These reasons sound like rhetoric from long ago, but it is very current. In this article, research is used to show that students who participate in inquiry learning or any type of problem-based education do much better than students who do not have that opportunity. The student participants not only have better grades, but they think on a higher level, become more civic minded, and are better problem solvers. Included in the article are four models which can be used to teach inquiry science, and two lesson plans with rubrics to help grade the inquiry STS lesson. The major point being made throughout is that there is an advantage to teaching students using inquiry. The only disadvantage is not giving the students the opportunity to use inquiry and to grow

The fundamental challenge: human and organisational factors in an ERP implementation

Organisations encounter obstacles when implementing ERP systems. This paper intends to explore some of the problems that occur throughout the implementation of an ERP system. Using a combination of the work of Markus et al (2001) and Kim et al (2005), a framework is constructed of Human and Organisational and Technical problems in ERP Implementations during the project phase. Drawing on empirical evidences from a UK furniture manufacturer, this study then discusses and analyses each problem identified in the framework and its affect on the implementation of their ERP system. The findings of this paper reveal that the fundamental challenge of ERP implementation is not technology but organisational and human problems, which, if not properly comprehended and addressed, can lead to ERP failure. Understanding that organisational and human issues are extremely important will encourage practitioners to address these problems and succeed in their ERP system implementations

The importance of a new product development (NPD) process: getting started.

In order to achieve a successful new product, and certainly the successful implementation of a new product into a company, it is necessary to have a structured and documented approach to New Product Development (NPD), therefore providing a clear roadmap for the development of new products. This review highlights the NPD process, from concept to consumer, and what the key success drivers are, such as; the quest for real product superiority and success, and the need for cross-functional teams; in order for a company to succeed and use new products as a source for competitive advantage

Teen Sexuality and Pregnancy in Nevada

We begin this report by examining recent data regarding the national and Nevada specific trends in teen sexuality and pregnancy and discuss the socioeconomic determinants and disparities in teen pregnancy. Next, we focus on the national and local policies and programs designed to reduce teen pregnancy and to promote health equity among teenage youth. We conclude with a survey of programs that provide housing, case management, mental health services, life skills, career counseling and teen parenting education in Las Vegas and in Henderson, NV. Appendix provides information about local and national community resources that readers can use to further their understanding of the issues raised in this chapter and learn more about the best practices designed to prevent teen pregnancies

Is E-learning replacing the traditional lecture?

Purpose – The purpose of this paper is to review some of the learning technologies associated with teaching and learning in Higher Education (HE). It looks at E-learning and Information Technology (IT) as tools for replacing the traditional learning experience in HE, i.e. the ‘chalk and talk’ lecture and seminar. HE is on the threshold of being transformed through the application of learning technologies. Are we on the brink of a new way of learning in HE after a tried and tested formula over eight hundred years? Design/methodology/approach – Adopting a case based approach, the fieldwork for this research took place at two UK Higher Education Institutes (HEI’s). A number of units that included IT based learning were identified. All units included a web site that was aimed at supporting students’ learning. The data was collected through unstructured discussion with the lecturer and a questionnaire to students. Findings – This paper considers and highlights the key findings from the sample linking them to the literature with the purpose of testing the aim/title of this paper. Evidence suggested the implications for HEI’s are they cannot assume that presenting new technologies automatically makes their institutions “youth friendly”; this new generation would like to see some concrete benefits of technology. Originality/value – From this small-scale investigation this paper attempts to investigate which direction the threshold may go. There has been eight hundred years of learning in the UK, is this generation wanting a new chapter. Evidence from this research suggests not, it will only play a bit part. They can help free up time in order to engage and support students in new and interesting ways

GraphBLAST: A High-Performance Linear Algebra-based Graph Framework on the GPU

High-performance implementations of graph algorithms are challenging to implement on new parallel hardware such as GPUs because of three challenges: (1) the difficulty of coming up with graph building blocks, (2) load imbalance on parallel hardware, and (3) graph problems having low arithmetic intensity. To address some of these challenges, GraphBLAS is an innovative, on-going effort by the graph analytics community to propose building blocks based on sparse linear algebra, which will allow graph algorithms to be expressed in a performant, succinct, composable and portable manner. In this paper, we examine the performance challenges of a linear-algebra-based approach to building graph frameworks and describe new design principles for overcoming these bottlenecks. Among the new design principles is exploiting input sparsity, which allows users to write graph algorithms without specifying push and pull direction. Exploiting output sparsity allows users to tell the backend which values of the output in a single vectorized computation they do not want computed. Load-balancing is an important feature for balancing work amongst parallel workers. We describe the important load-balancing features for handling graphs with different characteristics. The design principles described in this paper have been implemented in "GraphBLAST", the first high-performance linear algebra-based graph framework on NVIDIA GPUs that is open-source. The results show that on a single GPU, GraphBLAST has on average at least an order of magnitude speedup over previous GraphBLAS implementations SuiteSparse and GBTL, comparable performance to the fastest GPU hardwired primitives and shared-memory graph frameworks Ligra and Gunrock, and better performance than any other GPU graph framework, while offering a simpler and more concise programming model.Comment: 50 pages, 14 figures, 14 table

Scalable Breadth-First Search on a GPU Cluster

On a GPU cluster, the ratio of high computing power to communication bandwidth makes scaling breadth-first search (BFS) on a scale-free graph extremely challenging. By separating high and low out-degree vertices, we present an implementation with scalable computation and a model for scalable communication for BFS and direction-optimized BFS. Our communication model uses global reduction for high-degree vertices, and point-to-point transmission for low-degree vertices. Leveraging the characteristics of degree separation, we reduce the graph size to one third of the conventional edge list representation. With several other optimizations, we observe linear weak scaling as we increase the number of GPUs, and achieve 259.8 GTEPS on a scale-33 Graph500 RMAT graph with 124 GPUs on the latest CORAL early access system.Comment: 12 pages, 13 figures.
