Abstract

In cost‐benefit analysis the test that is most commonly adopted in order to apply the compensation principle is the Kaldor‐Hicks test, which is also referred to as the strong compensation test. This seeks to determine whether, after a policy move has taken place and new relative prices have been established, the gainers could hypothetically compensate the losers and still be collectively better off than before. Attention is also paid, in theory but seldom in practice, to the possibility of a Scitovsky paradox. This would arise if the Kaldor‐Hicks criterion is satisfied for both the policy move itself and its reversal. The Scitovsky double test can then be introduced in order to reject a policy move which produces such a result. A move passes this test if it both satisfies the Kaldor‐Hicks criterion in the forward direction and does not satisfy it in reverse.

Abstract

The purpose of this note is to provide a short synthesis of what may be called the traditional models of peak‐load pricing developed by Boiteux (1949), Steiner (1957), Hirshleifer (1958) and Williamson (1966), and reviewed by Crew and Kleindorfer (1979). The elements of the analysis are familiar but all the main features and conclusions, hitherto arrived at by methods that differ slightly from one another, can be seen in one simple model. We will use here the example of a public electricity authority by way of illustration, assuming that the basic unit of electric power is 1 kilowatt (KW) and that the overall time cycle is 24 hours long. There is assumed to be a finite number of time periods within this cycle, each of which exhibits a distinct level of demand which is both constant over time and independent of the demand in every other period. Other main assumptions which are usual in this kind of analysis are mentioned below.

Abstract

Purpose — In this chapter a case will be made for the importance of measuring well-being in transport mobility research. A number of well-being measures and determinants of well-being will be presented in reference to the current project. This chapter will then conclude with some practical recommendations for transport mobility researchers wishing to include well-being measures in their future studies.

Methodology — Measurement methods associated with previous transport mobility and well-being research will be critically examined so that strengths and limitations can be identified. The measurement approach to well-being adopted for the current project will be presented and associated challenges experienced by the research team will then be discussed.

FindingsA review of the extant transport mobility research which includes an assessment of well-being shows that it is not uncommon for unstandardised measures of well-being to be adopted. In addition, exploration of relationships between transport mobility and well-being are often undertaken without any consideration of potential moderating or mediating factors. More work is needed to advance our knowledge of the transport mobility and well-being relationship and the underlying mechanisms driving this relationship. Research also needs to focus on undertaking longitudinal studies which will enable causation to be established.

Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

Purpose

The purpose of this paper is to achieve stable grasping and dexterous in-hand manipulation, the control of the multi-fingered robotic hand is a difficult problem as the hand has many degrees of freedom with various grasp configurations.

Design/methodology/approach

To achieve this goal, a novel object-level impedance control framework with optimized grasp force and grasp quality is proposed for multi-fingered robotic hand grasping and in-hand manipulation. The minimal grasp force optimization aims to achieve stable grasping satisfying friction cone constraint while keeping appropriate contact forces without damage to the object. With the optimized grasp quality function, optimal grasp quality can be obtained by dynamically sliding on the object from initial grasp configuration to final grasp configuration. By the proposed controller, the in-hand manipulation of the grasped object can be achieved with compliance to the environment force. The control performance of the closed-loop robotic system is guaranteed by appropriately choosing the design parameters as proved by a Lyapunove function.

Findings

Simulations are conducted to validate the efficiency and performance of the proposed controller with a three-fingered robotic hand.

Originality/value

This paper presents a method for robotic optimal grasping and in-hand manipulation with a compliant controller. It may inspire other related researchers and has great potential for practical usage in a widespread of robot applications.

Abstract

Purpose

The Affordable Care Act is transforming health care practice nationwide through emphasis on population health and prevention. Health care organizations are increasingly required to address population health needs. However, they may be ill equipped to answer that call.

Design/methodology/approach

This study identified ways that health care organizations might better integrate public and population health efforts to better respond to this new emphasis on population health. Employing semi-structured key informant interviews, barriers to and facilitators of integration were explored and implications for health care and public health leaders were developed.

Findings

Participants (n = 17) – including senior hospital executives, group practice administrators, and health department officials – identified strategies for health care and public health leaders to more effectively integrate in order to achieve better performance and population health gains. These strategies and their implications are discussed.

Originality/value

The results of this study provide important value to health care administrators leading efforts to integrate population and public health.

Abstract

Purpose

The science of Foresight differs from the commonplace notion of what a science is because it is a metadiscipline – a logical type of science higher than the logical type of disciplinary sciences. It is practical, uses transdisciplinary processes that combine scientific disciplines and often examines counterfactuals in a scientific manner. This study aims to demonstrate that Foresight is a science, by presenting a number of best practices and potential innovations in higher education that could facilitate obtaining skills for Foresight science.

Design/methodology/approach

The methods of scientific education that have served us well in the past are inadequate for metadisciplinary sciences such as Foresight. The paper discusses what metadisciplinarity is, using a variety of examples, and distinguishes it from disciplines and ways of crossing disciplinary boundaries. Understanding the essential characteristics of Foresight as a metadisciplinary science leads to identifying current best practices and possible educational innovations in undergraduate education that will facilitate obtaining Foresight skills. Throughout the paper, examples are drawn from the education and professional experience of the author in the USA and Europe.

Findings

This paper demonstrates that Foresight is a science and presents a number of best practices and potential innovations in higher education that could facilitate obtaining skills for Foresight science. It identifies barriers to those innovations and approaches to overcome them.

Originality/value

This viewpoint paper clarifies the meaning of the terms interdisciplinarity, transdisciplinarity and metadisciplinarity to identify the essential characteristics of Foresight as a science. Then, it identifies and advocates needed changes in North American higher education to provide earlier and more efficient opportunities for Foresight researchers and users to obtain the skills they need.

Abstract

Purpose

This study sought to understand which food allergen labeling systems (non-directive, semi-directive, and directive) were attended to and preferred by 34 participants with food hypersensitivity and their perceived corporate social responsibility (CSR) and behavioral intention towards a restaurant that identifies food allergens on menus.

Design/methodology/approach

This study used an online survey with open-ended and ranking questions, combined with eye-tracking technology, to explore participants' visual attention and design preferences regarding four menus. This study utilized one-way repeated measures analysis of variance (RM-ANOVA) and heat maps to analyze participants' menu-reading behaviors. A content analysis of survey responses and a ranking analysis of menus were conducted to understand the reasons behind consumers' preferred menu designs.

Findings

The advisory statement was not much attended to. Participants identified food allergen information significantly quicker with the directive labeling system (icons) than the other two systems, implying they were eye-catching. Semi-directive labeling system (red text) has lower visit count and was more preferred than two other systems; each labeling system has its strengths and limitations. Participants viewed restaurants that disclosed food allergen information on menus as socially responsible, and they would revisit those restaurants in the future.

Originality/value

This study was one of the first to explore, through use of eye-tracking technology, which food allergen labeling systems were attended to by consumers with food hypersensitivity. The use of triangulation methods strengthened the credibility of the results. The study provided empirical data to restauranteurs in the US on the values of food allergen identification on restaurant menus, although it is voluntary.

Abstract

Purpose

The purpose of this paper is to propose and evaluate the method for grasping a defined set of objects in an unstructured environment. To this end, the authors propose the method of integrating convolutional neural network (CNN)-based object detection and the category-free grasping method. The considered scenario is related to mobile manipulating platforms that move freely between workstations and manipulate defined objects. In this application, the robot is not positioned with respect to the table and manipulated objects. The robot detects objects in the environment and uses grasping methods to determine the reference pose of the gripper.

Design/methodology/approach

The authors implemented the whole pipeline which includes object detection, grasp planning and motion execution on the real robot. The selected grasping method uses raw depth images to find the configuration of the gripper. The authors compared the proposed approach with a representative grasping method that uses a 3D point cloud as an input to determine the grasp for the robotic arm equipped with a two-fingered gripper. To measure and compare the efficiency of these methods, the authors measured the success rate in various scenarios. Additionally, they evaluated the accuracy of object detection and pose estimation modules.

Findings

The performed experiments revealed that the CNN-based object detection and the category-free grasping methods can be integrated to obtain the system which allows grasping defined objects in the unstructured environment. The authors also identified the specific limitations of neural-based and point cloud-based methods. They show how the determined properties influence the performance of the whole system.

Research limitations/implications

The authors identified the limitations of the proposed methods and the improvements are envisioned as part of future research.

Practical implications

The evaluation of the grasping and object detection methods on the mobile manipulating robot may be useful for all researchers working on the autonomy of similar platforms in various applications.

Social implications

The proposed method increases the autonomy of robots in applications in the small industry which is related to repetitive tasks in a noisy and potentially risky environment. This allows reducing the human workload in these types of environments.

Originality/value

The main contribution of this research is the integration of the state-of-the-art methods for grasping objects with object detection methods and evaluation of the whole system on the industrial robot. Moreover, the properties of each subsystem are identified and measured.
