The simulation of industrial robot systems

This paper describes the GRASP computer aided design system for modelling and evaluating industrial robot workplaces. GRASP satisfies a range of simulation needs within the context of designing, implementing and operating industrial robotic systems. The GRASP software may be used to investigate robots operating by themselves or, more likely, as part of an integrated cell. Facilities within GRASP assist workplace layout, position and velocity evaluations, clash detection and co-ordination between items. A robot library exists and is being extended, and an embryo off-line programming facility has been used under restricted conditions. GRASP has been used to help solve a wide range of practical industrial robot problems and has proved itself technically, and also as an educational tool, by showing how a proposed system would operate. The paper describes the facilities within GRASP.     

More Like Us: The Effect of Immigrant Generation on College Success in Mathematics

This article investigates the impact of immigrant generation on students performance in college calculus courses and examines the extent to which the observed patterns corroborate or contradict various assimilation theories. It goes beyond past studies of the relationship between immigrant generation and mathematics achievement that focused primarily on middle and high school students and typically excluded foreign students. Our principal finding is that foreign students and the 1.25 generation earned the highest grades, on average, even after controlling for race/ethnicity and socioeconomic status. Our findings provide partial support for the immigrant advantage theory.     

A RESTRICTED MAXIMUM LIKELIHOOD PROCEDURE FOR ESTIMATING THE VARIANCE FUNCTION OF AN IMMUNOASSAY

Restricted maximum likelihood (REML) is a procedure for estimating a variance function in a heteroscedastic linear model. Although REML has been extended to non-linear models, the case in which the data are dominated by replicated observations with unknown values of the independent variable of interest, such as the concentration of a substance in a blood sample, has not been considered. We derive a REML procedure for an immunoassay and show that the resulting estimator is superior to those currently being used. Some interesting properties of the REML estimator are derived, and its relationship to other estimators is discussed.     

Role of Cognitive Styles in Business and Management: Reviewing 40 Years of Research

In line with increased attention on the application of cognitive approaches to industrial, work and organizational psychology, the last 40 years have witnessed a growing interest in application of the cognitive style construct to the field of business and management. The purpose of this paper is threefold. First, we wish to advance understanding of cognitive styles research by elucidating trends and perspectives related to business and management. Second, we identify gaps in the literature and promising areas of research that can be further developed. This is accomplished by means of a review of papers published between 1969 and 2009. Eight themes emerged from our analysis: (a) vocational and occupational issues; (b) national culture; (c) teamwork and interpersonal relationships; (d) learning; (e) decision making; (f) creativity, innovation and entrepreneurship; (g) sales and marketing; and (h) management information systems, information management and use. Third, we identify valid and reliable methods of assessment of cognitive style for use in business and management settings. Finally we draw a number of conclusions regarding the current state of cognitive styles research and promising directions for future research.     

Executive pay, tournaments and corporate performance in UK firms

This paper explores the relationship between executive pay and corporate performance. First, we focus on the pay-for-performance sensitivity (PPS), review recent evidence (mainly UK) and outline a methodology for calculating the PPS itself. Secondly, we review the evidence on tournament theory. Tournament models predict that career concerns generate incentives for executives and can explain observed variations in pay outcomes in the boardroom. Thirdly, we provide evidence on the distribution of the PPS for 532 executives within 100 large UK stock market companies for 1997. Unlike prior work, we include non-CEO executives in the analysis. We show that the PPS increases through organizational levels. Also the statistic is not constant across firms. Finally, we consider the relationship between corporate performance and incentives. We show, consistent with prior evidence, that there is a positive relationship between firm performance and the effective ownership of stock-based compensation by management.     

Beyond privacy: bodily integrity as an alternative framework for understanding non-consensual pornography

ABSTRACT

Activists and legal scholars seeking remedies to non-consensual pornography (known colloquially as ‘revenge porn’) have generally framed it as a violation of privacy; however, the concept of privacy a fraught history, linked to women’s exclusion from the public sphere, denial of their sexual expression, and impunity for abusers. I argue that the concept of body integrity better maps onto the experiences described by victims, who seldom distinguish between digital representations of their body and the body itself and who often liken non-consensual pornography to sexual assault. However, a feminist approach to bodily integrity (rather than one rooted in classical liberalism) is require in order to account for the disproportionately negative consequences non-consensual pornography has for women.
