Abstract

Purpose

The purpose of this paper is to analyze surface deformations caused by shear and moment forces on tactile materials and present a method to detect and reduce the risk of slippage by controlling the normal force as measured by tactile sensor arrays.

Design/methodology/approach

A predictive model has been proposed which uses a basic method adapted to real applications in grasp optimization. Prevention of premature release with minimum prehension force is addressed without the need to measure the coefficient of friction between object and robot gripper. Predictive models have been used to develop a set of rules which predict the pre‐slip based on fluctuations in tactile signal data.

Findings

The tactile sensors can be used in a “nonlinear” manner during manipulation tasks. When the gripper finger first makes contact with an object, the stress distribution under the finger skin varies rapidly. Predictive models have been used to develop a set of rules which predict the pre‐slip based on fluctuations in tactile signal data. Pre‐slip at the contact area just prior to object movement produces rapid but detectable stress transients.

Originality/value

Tactile sensors do not measure stress generated by a contact with an object directly, but instead measure strain in an interposed compliant, polymeric medium intended for sensor protection and prehension assistance. Reliable detection of pre‐slip has hitherto eluded researchers using such tactile techniques.

Abstract

Purpose – Using Whitehead's notion of prehension in a critical reappraisal of phenomenology, a different kind of understanding of subjectification and objectification is being proposed in which subjectification is that which enables action as a multiplicity or virtuality, and objectification enables actuality.

Approach – A critical engagement with literature on objects, including Gabriel de Tarde, Alfred North Whitehead, Martin Heidegger and Graham Harman, is used to develop an original conception of objectification and subjectification. This is applied to debates about objectification in pornography.

Findings – This approach enables us to better understand the theoretical underpinnings of empirical philosophies such as Actor Network Theory in support of the argument that objects are capable of action. While subjectification is folded within the process of prehension as the opening of the virtual, it is logically possible to argue that objects are a matter of concern for ethics. This also means that in terms of the pornography debate, the pornographic object as such can be held accountable. We do not have to accept the instrumentalist argument that ‘what you do with it defines its ethics’.

Originality/value – The argument that objects are capable of action has thus far not been pursued in relation to questions of ethics as opposed to politics.

Abstract

Habraken points out that the architectural studio failed to bring students to basic questions in the architecture of everyday environments. Till criticizes that in a studio, it is only the professional value represented by the teachers that prevails. To investigate the reasons of the allegation, this paper introduces a learning model defined by David A. Kolb, in which a learning process consists of two dimensional movements: i.e., prehension (concrete experiences vs. abstract conceptualization) and transformation (reflection and experiment). The paper then inquires into Schön's observation in the studio learning mode characterized as reflection-in-action. It is found that this studio is mainly dealing with the transformation dimension, and prehension dimension is either suppressed or represented by the teacher's experiences and conceptions. The paper discovers that the cause of problems raised by Habraken and Till is the inherent lack of substance in the prehension dimension.

The paper assesses a studio programme in which the basic questions of built environment were systematically introduced. It analyzes the students' reactions and performance in line with students' learning styles found using Kolb's Learning Style Inventory (LSI). It suggests that the students' learning activities are more diversified than what Schön could perceive. There is a possibility to adapt students' personal experience and abstract conceptualization which may play into the studio. By enhancing diversity of learning styles rather than letting one's learning style (reflection-in-action) prevail, the studio may become a platform in which students may learn from each other.

Abstract

Using an industrial assembly robot to manipulate objects of significantly differing shapes is practically impossible without a universal prehension organ. Robot grippers of great simplicity and dependability are too specific to one particular geometry, whereas existing, complicated grippers, though more universal in nature, are, with only several exceptions, not designed for use in industrial surroundings, being products of prosthetics research or Artificial Intelligence programs Required gripping modes for multiple‐prehension grippers and resulting design constraints are discussed. A computerized optimisation technique for determining applicability of straight‐line‐producing four‐bar linkages is explained. A multiple‐prehension, three‐fingered gripper is proposed that, while being relatively robust, allows reliable gripping of many forms commonly found in light assembly operations.

Abstract

In this study we consider the role of business management in delivering good in society, from the perspective of the philosophical work of Adam Smith, Karl Marx and Alfred North Whitehead. We find that Whitehead's process explanations of the nature of experience and consciousness articulate meaningfully with Smith's idea of ‘self-love’ and Marx's conceptualisation of ‘rich-experience’. As a result, we argue that business practice must reconnect with society in a more appropriate understanding of a good as something beyond a mere economic entity. Using principles of process thought, we make recommendations as to how this might be achieved in daily management practice.

Abstract

Piezoelectric actuators are well established for use in expensive optical equipment. Within the last decade, relatively inexpensive piezoelectric actuators have become established technology in pneumatic switching and the first piezoelectrically driven impactive robot grippers are just starting to emerge. Although this article concentrates largely on the use of piezoelectric actuators for use in robot gripping systems, the potential for applications outside this field is immense.

Abstract

Purpose

The purpose of this paper is to provide a coherent, comprehensive and complete philosophical framework that can not only validate but also guide the implementation of the organisational development strategies proposed in Presence: Exploring Profound Change in People, Organizations and Society.

Design/methodology/approach

First, the paper situates the processes presented in the text within the overall context of current organisational development theory. Then, since no current widely supported philosophical framework can provide validation and support to the fundamental assumptions inherent within the text's proposals, a new philosophical framework is described. Finally, the unique insights gained from this new philosophical framework are used to offer prerequisite considerations for employing the processes proposed here.

Findings

Unless explicit and individualised attention is directed to helping each employee first develop deeply self‐reflective processes, the organisational insights and practices, as presented in the work cited above, cannot be attained.

Practical implications

Through applying the theoretical insights gained from the particular philosophical framework presented herein, the paper provides very clear and specific guidelines for the professional development of employees so that they can act according to the precepts presented in the work cited above.

Originality/value

The paper provides a unique perspective on the key understandings presented in the work cited above. It also provides practical ways for successfully engendering these within an organisation's culture.

Abstract

The virtuous character and the ethical agent represent mutually inclusive terms, neither of which independently, in the Aristotelian tradition, is considered an innate quality. Virtues, if not innate, are contingent; but what makes each instantiation recognisably general? Normative ethics in this sense is a dynamic process and similarly process philosophy is based on the principle that existence is dynamic and that it should be the primary focus of any philosophical account of reality. I argue that the transformative process is equally as important as the end result of realising the virtuous dispositional traits. An important criticism of virtue ethics is the focus on character and not rules such as industry practices and codes found in the professions. The criticism however is less worrisome than usually accepted. The reasoning herein developed to overcome this criticism rests on the presupposition that no one exists in isolation and virtues are developed in a social context and not simply given. Using process philosophy as a methodological approach to examine virtue ethical agency and the transformative process involved in its realisation elicits insights that allow the conceptual development of a more robust account of virtue ethics. I extend this nuanced rendition, in ways already commenced by others, into areas of organisational, environmental and intergenerational ethics.

Abstract

This chapter proposes a conceptual synthesis able to think media and mediation through affect theory. Its objective is to expand our traditional conceptual frame with a new concept: immediation. Through its capacity to render the power of affect’s sociality, immediation enables us to better grasp the social life of affectivities underlying every media experience. William James defines “pure experience” as the “primal stuff of material in the world, a stuff of which everything is composed” (2003, p. 2). This is “relation,” understood as a passage where affective lines of creation come together as one “concrescence” (Whitehead, 1978). How does the binding of these affective variations occur, giving pure experience the power to express itself as an esthetic feeling? Alfred North Whitehead’s answer to this question revolves around his notion of “society” (1978). It points to a virtual society composed of affective forces. Considering that “pure experience” is a process, it would be reasonable to conceive of it as passing a threshold in its becoming. Clearly, this threshold is not fixed, but rather a “mobile differentiation” (Massumi, 2002, p. 34) – emerging from the internal cohesion of the event of experiencing an esthetic quality. It should thus be understood as a process of emergence (or an actualization of virtuality). Affective passages, events, processes of emergence, and intensities are pulsations of radical novelty. They consist in what qualitatively happens in experience: what emerges as an event. Consequently, what happens to the concepts of media and mediation if we think them through this conceptual lens?
