Displacements of a miscible magnetic layer in a capillary tube under a moving ring‐shaped magnet are studied numerically. The magnet is adjusted dynamically to maintain a constant distance from the front mixing interface on the centerline. Control parameters, such as magnetic strength, effective viscosity variation due to magnetization, diffusion and the position of the magnet, are analyzed systematically. Motion of the magnetic layer is evaluated by two quantitative measurements, i.e. movement of center of gravity and spread of layer width. In general, the moving speed of the center of gravity depends only slightly on the magnetic strength, and is found slower at a higher viscosity ratio and a closer placement to the front interface as well if the magnet is placed amid the layer. A weaker spread occurs in situations of stronger magnetic strength, lower viscosity parameters and also placements near the rear interface. A multi‐front finger results if the magnet is positioned ahead of the front interface.

Location awareness is essential to decisions pertinent to tracking and progress reporting, as well as to safety in construction projects. However, these applications have been mostly limited to the outdoor environment, where satellites for positioning information are in view. Recent studies on indoor location sensing systems are now overcoming this limitation and offering significant potential on construction practices, and radio frequency identification (RFID) is the most widely utilised technology for such application. The purpose of this paper is to address a wide range of protocols that are vital for RFID deployment for indoor construction. The paper identifies deployment settings to provide data acquisition with higher accuracy for indoor location sensing in construction.

A computational platform was designed to assess and evaluate the most suitable condition related to deployment of reference tags in construction. In this platform, a number of protocols and parameters are presented and their performance is evaluated. The evaluation scenarios were performed on a construction facility in Montreal, as well as in a controlled lab environment. The computational platform used for the study comprises the use of passive reference RFID tags and K Nearest Neighbour algorithm (K‐NN) for course‐grained detection of target's location and its classification into pre‐defined zone areas.

The studies resulted in a number of observations, findings, and lessons learned for RFID deployment in construction. The results indicate that: the speed of the reader is in direct relationship with the detection error rate; zone configuration effectiveness is in direct relationship with the deployed RFID read‐range; error rate on the controlled environment is significantly lower than rates in construction site; and stationary reader performs better than moving reader.

The paper's findings are expected to be of considerable value to researchers and practitioners involved in the utilisation of RFID technology in construction. The paper provides a set of helpful protocols for the deployment of passive RFIDs for automated onsite management of construction operations.

Law and Film both enjoy the power to mediate the social imaginary. Here, we explore the resonance of this insight in the register of affect and intensity, movement, and change. This demands a different approach to doing theory. As Andrew (1976, pp. 66–67) argues, ‘film is not a product but an organically unfolding creative process in which the audience participates both emotionally and intellectually.’ Seeing a film is not just an exercise in imagining alternatives; it is an unfolding experience in time. It is an event shaded with particular embodied dimensions: one's heart races, pupils contract, skin shivers, muscles tense. Involuntary sensations of nausea or vertigo combine with cognitive responses to produce the lived experience of viewing a particular film that is incorporated into one's sensibility, sometimes very powerfully. It is not just that the mind has spent time in a darkened theatre. The body has also had an affect-laden auditory, visual, and tactile encounter. The affect-rooted experience of the film is a piece of the subject's past, its history, its self. This is another way to understand how film not only represents the world, but participates in its making.

IN a departure from usual practice this issue concentrates to a large extent upon a single subject — Mechanical Handling. It coincides with that industry's exhibition at Earls Court from the 9th to 19th of this month, to be opened by the Rt. Hon. Christopher Chataway, M.P., Minister for Industrial Development. In consequence it was necessary to defer some regular features for a time, for which we apologise.

The purpose of this paper is to examine what the term sustainable fashion means from the perspective of micro-organisations, experts, and consumers.

This research is qualitative in nature, utilising a multi-methods case study approach (semi-structured interviews, semiotics, questionnaires). Grounded analysis was applied to analyse the data.

Findings indicate that interpretation of sustainable fashion is context and person dependent. A matrix of key criteria provides the opportunity to find common elements.

Due to the nature of this research the sample size is limited and may not be generalised. Data were collected in the UK and are limited to a geographical region.

An important implication is that defining sustainable fashion is vital in order to avoid challenges, such as greenwashing, which were faced in other industries that have a longer history in sustainable practices. Micro-organisations should take advantage of identifying key sustainable fashion criteria, which will enable them to promote their fashion collections more effectively.

The criteria identified provide assurance for consumers that sustainable fashion is produced with social aspects in mind (fair wages, good working conditions).

The paper proposes a matrix that allows micro-organisations to clearly identify their collections as sustainable.

Based on research in Midland Bank plc, the importance of the “subjective”, “informal” and “political” aspects of the promotion process are highlighted. It is argued, and many graduates perceive, that the ability to get promoted is a quite separate ability from that required to do the job. The “soft” side of promotion, i.e. understanding “culture”, “labelling”, “cognisance”, “routes”, “sponsors” and so on, is the key to the management of the promotion process.

Gives a definition of merchandising explaining how and why it works effectively. Discusses its power and cost‐effectiveness as a means of ensuring a final pre‐purchase exposure of consumers to persuasive or informative material. Investigates five merchandising techniques: manipulation of store traffic flow; shelf positioning; allocation of limited shelf space between competing claims; use of point‐of‐sale material; and special displays. Shows how these can be used profitably by the retailer and wholesaler. Presents a ten‐part plan for an organized approach to merchandising.
