Abstract

Several pick‐up devices have been proposed and invented for automated garment handling but a scientific understanding of picking up operation is incomplete. This paper is an extension of earlier studies into modelling the interaction of the performance of pinch gripper and the properties of flexible material (foam). Here, the relationship between the performance of pinch gripper (size and shape), external load, deformation and the properties fabric is investigated. The distributions of stress and strain within a fabric under differently shaped grippers (flat and curved) are revealed. The main factors affecting the first step of picking up action‐two pegs pushing down on the top of fabric are identified. Experiments have been carried out on single‐ and multi‐layer fabrics, and the accuracy of the models is demonstrated through comparison of the predicted results with the experimental data. This study is aimed towards optimisation of design of a gripper and providing knowledge for an intelligent grasping system of fabric handling.

Abstract

This paper takes as its starting point observations and concerns of quality assurance staff in UK HEIs about the use of computer‐assisted assessment (CAA) collected in the 1999 National Survey into CAA. The issues raised are grouped into three categories: pedagogical; operational; and institutional; and the quality assurance issues for each area are addressed. Emphasis is placed on the institutional management of CAA, the development of quality assurance regulations and protocols and the evaluation of CAA systems. The paper makes suggestions about the co‐ordination of CAA within an institution and speculates on the future developments in computerised assessments and the increased importance of ensuring quality.

Abstract

This chapter describes how conversational computer agents have been used in collaborative problem-solving environments. These agent-based systems are designed to (a) assess the students’ knowledge, skills, actions, and various other psychological states on the basis of the students’ actions and the conversational interactions, (b) generate discourse moves that are sensitive to the psychological states and the problem states, and (c) advance a solution to the problem. We describe how this was accomplished in the Programme for International Student Assessment (PISA) for Collaborative Problem Solving (CPS) in 2015. In the PISA CPS 2015 assessment, a single human test taker (15-year-old student) interacts with one, two, or three agents that stage a series of assessment episodes. This chapter proposes that this PISA framework could be extended to accommodate more open-ended natural language interaction for those languages that have developed technologies for automated computational linguistics and discourse. Two examples support this suggestion, with associated relevant empirical support. First, there is AutoTutor, an agent that collaboratively helps the student answer difficult questions and solve problems. Second, there is CPS in the context of a multi-party simulation called Land Science in which the system tracks progress and knowledge states of small groups of 3–4 students. Human mentors or computer agents prompt them to perform actions and exchange open-ended chat in a collaborative learning and problem-solving environment.

Abstract

Most citation analyses are based on references taken from two or three source journals. There are good theoretical reasons for believing that these may not be representative of all references. In the social science citation analyses carried out as part of the DISISS programme, references were collected from 140 journals, including forty‐seven drawn at random from a comprehensive list, and also from 148 monographs. Analyses of references drawn from high ranking and randomly selected journals showed differences in date distribution, forms of material cited and rank order of journals cited. Analyses of references drawn from journals and monographs showed differences, some of them large, in date distributions, forms of material cited, subject self‐citation and citations beyond the social sciences, and countries of publication cited. These differences may be peculiar to the social sciences, but any citation analyses that are based on only a limited number and type of sources without specific justification must be regarded with suspicion.

Abstract

Purpose

The study of nanoindentation as a reliable method to extract creep properties as well as for fundamental understanding of deformation mechanisms at small length scales is an open interesting field. The observed creep behavior is attributed to time-dependent plastic deformation based on loading rates. There is a lot of work in the field of nanoindentation in order to understand the dynamic effects on nanomechanical properties. The paper aims to discuss these issues.

Design/methodology/approach

The deformation mechanism is investigated under two experimental approaches (high and low loading rates, respectively) during nanoindentation. The effect of loading rate in the nanomechanical properties, during nanoindentation creep of zinc layer on hot dip galvanized (HDG) steel, is discussed through nanoindentation.

Findings

Analysis of this research effort is emphasized on nanoindentation stress exponent, a critical parameter for the life time and reliability of nano/micro-materials and systems. The corrosion resistance was studied by electrochemical impedance spectroscopy (EIS) and localized EIS.

Abstract

Purpose

The purpose of this paper is to propose a unified definition of integrated palliative care (IPC), and to identify the elements that facilitate or hinder implementation of an integrated palliative care system (IPCS).

Design/methodology/approach

A scoping review of the conceptualization and essential elements of IPC was undertaken, based on a search of the PubMed, Scopus and ISI Web of Science databases. The search identified 79 unduplicated articles; 43 articles were selected for content analysis.

Findings

IPC is coordinated and collaborative across different health organizations, levels of care and types of providers. Eight key elements facilitate implementation of an IPCS: coordination, early patient identification, patient-centered services, care continuity, provider education and training, a standard implementation model and screening tool, shared information technology system, and supportive policies and funding. These elements were plotted as a “Circle of Integrated Palliative Care System Elements.”

Practical implications

This paper offers researchers an inclusive definition of IPC and describes the essential elements of its successful implementation.

Originality/value

This study provides evidence from researchers on five continents, offering insights from multiple countries and cultures on the topic of IPC. The findings of this thematic analysis could assist international researchers aiming to develop a standard evaluative model or assess the level of integration in a health care system’s delivery of palliative care.

Abstract

An existing tension in sociological and criminological research with young people is the need to seek parental consent for research participation, while acknowledging that providing parents with descriptions of the research may put youth in precarious positions. This is particularly true when discussing sensitive topics such as interpersonal violence, gang involvement, and/or LGBTQ identity. One mechanism to maximize research participant protections while still preserving their privacy is to utilize independent youth advocates during the consent and research processes, sometimes by sampling with the assistance of youth-serving community agencies. Although such arrangements can be mutually beneficial for research participants, scholars, and the agencies themselves, concerns about strain on agency staff, ownership of data/results, how to engage in meaningful collaboration, conflicts of interest, funding, and other related issues also exist. This chapter draws from our recent investigation of the social worlds of urban LGBTQ youth to discuss the ethical and practical considerations of utilizing the assistance of youth advocates and community agencies. We also articulate how the case for utilizing youth advocates can be made to university Institutional Review Boards (IRBs) by directly citing the federal guidelines regarding research with minors.

Abstract

Purpose

This paper presents an experimental study of the influence of variables such as strain rate, the number of fabric plies, the type of fabric, the kinds of fibre and the shape of indenter on the indentation of fabric under differently shaped pinch gripper.

Design/methodology/approach

This experimental study will be approached from three different angles. It will look into an indenter pressing a sample with a much larger size, which is important in practice in the world of grasping by a pinch gripper. It will research a flat indenter, but also an indenter with a curved surface and will investigate fabric compression particularly with regard to the differences between single‐layer and multi‐layer stacks.

Findings

The type of fabric architecture and the kind of fibre have been proven to be important for the indentation. Even more important is the indenter geometry. Evidence collected to date suggests that the grasping action is more sensitive to indenter geometry. This leads to three possible approaches: close regulation of the materials and processes, handling processes to change in the material properties, and thirdly, intelligent systems which can learn from and adapt to each situation.

Research limitations/implications

This study suggests that a picking up operation should change in the material properties, that is, the operation should be controlled by using fabric characteristics as the control information in an intelligent environment.

Originality/value

Previous work on compression has been concentrated on an indenter with a size identical to a specimen, this study will look into an indenter pressing a sample with a much larger size. On compression, previous work has focused on single‐layer fabric compression by a flat indenter, but this research will not only research a flat indenter and single layers, but also an indenter with a curved surface, and multi‐layer stacks.
