Effect of high resistive barrier on earthing system
Substation earthing provides a low impedance path and carries current into ground under normal and fault conditions without adversely affecting continuity of service. Under a fault condition, the ground voltage may rise to a level that may endanger the public outside the vicinity of the substation. In such a case a high resistive barrier can be inserted around the vicinity of the substation to reduce the surface potentials immediately beyond the barrier. In this paper the effect of barrier on the overall performance of the earthing system has been investigated experimentally and computationally based on an earthing system consisted of combined grid and rods in a water tank. The effect of the position and depth of the barrier to the resistance of the earthing system and surface potentials in and around the substation have been examined
Bobbles and values: An ethnography of de-bobbling garments in postsocialist urban Romania
Based on research on clothing consumption in a provincial Romanian town, this article focuses on bobbling (pilling) and on reflections on its appearances and progression. Bobbling is considered an index of a faulty or decaying materiality, and an index of usage and, possibly, carelessness and hardship. It limits an individual’s ability to project a desired self. It hints at an individual’s inability to present a renewed self. It not only disrupts a common process of value creation through the act of dressing, but also exposes a disputed process of value creation through the consumption of certain objects. It foregrounds a predisposition to equate the value of objects with the value of people. It affects a sense of self-worth. The author demonstrates that a preoccupation with bobbling reflects deeper concerns and frequent deliberations over value in postsocialist Romania

When do actively controlled visual events guide our attention?
Visual attention and action seem to be interdependent. In a recent study (Pilling & Barrett, 2017), participants performed a visual search task, searching for non-tilted target ellipses, periodically changing orientation from left to right, amongst left-or-right tilted distractor ellipses, also changing orientation. Participants were substantially better at locating the target during active-control trials in which they controlled the target’s orientation change, than in passive-control trials, where the change was computer controlled. However, it was unclear whether this action-control advantage only occurs under the specific conditions of the original study, where the rate at which distractors changed orientation was kept constant and the number of distractors (set size) varied. The present study identified whether this action-control advantage was more prominent under certain conditions by varying the rate at which distractors change orientation, whilst keeping set size constant, on participants’ attention to active and computer-controlled visual stimuli. The distractor orientation change occurred in a regular or random-change-pattern and target orientation change was participant or computer controlled. Twelve participants performed a visual search task on a computer. The search-displays consisted of 20 coloured ellipses (1 target and 19 distractors). During active- and passive-control trials, the target stimulus changed orientation horizontally/vertically, which participants had to report. The results showed participants were quicker at locating target stimuli in active-control trials, when distractors changed orientation at a slow or moderate rate. This was found regardless of change-pattern. The results demonstrate the importance of action-attention relationships, showing the limits of the conditions under which such effects are prevalent

Exploring roles and relationships in the production of the built environment
Given the number of different agencies and the complexity of institutional and professional relationships in the production, management and regulation of the built environment, many students entering built environment professions leave university education to take up work placements or employment without a sufficient understanding of the different actors and the formal and informal interactions and social relationships between them. Furthermore, destructive stereotypes may form during the educational process as students construct their own professional identity, in part learnt from their teachers and peers, and naturalised by the academic and professional institutions that form the context of their education – a process of enculturation termed ‘professional socialization’ by social scientists (Cuff, 1991: 118). These stereotypes may lead ultimately to inter-professional tensions and hostilities. Innovations in practice often involve challenges to established roles or joined-up thinking which breaches institutional structures, for all of which graduates may be ill-prepared
