Abstract

Tasks in automated manufacturing and assembly increasingly involve robot operations guided by vision systems. The traditional “look‐and‐move” approach to linking machine vision systems and robot manipulators which is generally used in these operations relies heavily on accurate camera to real‐world calibration processes and on highly accurate robot arms with well‐known kinematics. As a consequence, the cost of robot automation has not been justifiable in many applications. This article describes a novel real‐time vision control strategy giving “eye‐to‐hand co‐ordination” which offers good performance even in the presence of significant vision system miscalibrations and kinematic model parametric errors. This strategy offers the potential for low cost vision‐guided robots.

Abstract

Purpose

This narrative review explored the efficacy of school-based child sexual abuse prevention programmes between 1990 and 2002. There were 22 efficacy studies that met clear inclusion criteria. Results covered both methodological design and the range of outcome measures. Methodology was analysed through four dimensions (target population, prevention programme implementation, evaluation methodology and cost-effectiveness). Outcomes for children covered nine categories (knowledge, skills, emotion, perception of risk, touch discrimination, reported response to actual threat/abuse, disclosure, negative effects and maintenance of gains). The studies had many methodological limitations. Prevention programmes had a measure of effectiveness in increasing children ' s awareness of child sexual abuse as well as self-protective skills. Beyond minimal disclosure rates, there was no evidence to demonstrate that programmes protected children from intra-familial sexual abuse. For a small number of children prevention programmes produced minimal negative emotional effects. Recommendations for future research, policy and practice, include realistic outcomes for child participants and locating programmes within wider abuse prevention measures.

Abstract

A growing body of research outlines how to best facilitate and ensure methodological rigor when using dictionary-based computerized text analyses (DBCTA) in organizational research. However, these best practices are currently scattered across several methodological and empirical manuscripts, making it difficult for scholars new to the technique to implement DBCTA in their own research. To better equip researchers looking to leverage this technique, this methodological report consolidates current best practices for applying DBCTA into a single, practical guide. In doing so, we provide direction regarding how to make key design decisions and identify valuable resources to help researchers from the beginning of the research process through final publication. Consequently, we advance DBCTA methods research by providing a one-stop reference for novices and experts alike concerning current best practices and available resources.

Abstract

This paper addresses revolutionary changes in the education, fertility and market work of U.S. families formed in the 1870s–1920s: Fertility fell from 5.3 to 2.6; the graduation rate of their children increased from 7% to 50%; and the fraction of adulthood wives devoted to market-oriented work increased from 7% to 23% (by one measure).

These trends are addressed within a unified framework to examine the ability of several proposed mechanisms to quantitatively replicate these changes. Based on careful calibration, the choices of successive generations of representative husband-and-wife households over the quantity and quality of their children, household production, and the extent of mother’s involvement in market-oriented production are simulated.

Rising wages, declining mortality, a declining gender wage gap, and increased efficiency and public provision of schooling cannot, individually or in combination, reduce fertility or increase stocks of human capital to levels seen in the data. The best fit of the model to the data also involves: (1) a decreased tendency among parents to view potential earnings of children as the property of parents and (2) rising consumption shares per dependent child.

Greater attention should be given the determinants of parental control of the work and earnings of children for this period.

One contribution is the gathering of information and strategies necessary to establish an initial baseline, and the time paths for parameters and targets for this period beset with data limitations. A second contribution is identifying the contributions of various mechanisms toward reaching those calibration targets.

Abstract

This chapter explores the potential for and value of imagining a humanist paradigm for tourism studies. It explores how the idea of a “paradigm” in tourism can be conceptualized, arguing that dominant thoughtlines in other fields regarding the meaning of a paradigm are not sufficient for making sense of this idea in the context of tourism studies. The chapter introduces humanism as a philosophical position in the academy and as a lived cultural practice, explores examples of extant work in tourism studies that might be seen to provide the seeds of a humanist paradigm, and offers reflections on the value of imagining such a paradigm for our field.
