Purpose The purpose of this paper is to analyse site managers’ ICT preferences for monitoring resource use in refurbishment projects. Design/methodology/approach Information and communication technologies (ICT) developments for the construction industry are increasing the scope for more efficient planning and monitoring of refurbishment projects. The analysis is based on the unified theory of acceptance and the use of technology model. After a short initial survey, a Swedish web/postal questionnaire has received 78 responses from refurbishment site managers, implying a 34 per cent response rate. Findings Managerial choices related to ICT depend more on perceived performance expectancy than on effort expectancy. Large projects and larger firms are associated with more extensive ICT use. Site managers see little need to link to refurbishment clients’ ICT systems. Performance expectancy and age are found to influence ICT choices. Practical implications Site managers play a crucial role in everyday use of ICT tools in the construction industry. The outcome of this investigation is useful for developing digital support, including applications of building information modelling, to improve refurbishment site practices. Originality/value Much has been written about ICT support for new construction practices, but not much attention has been paid to refurbishment site managers’ media choices.

Target Set

The scientific community is active in developing new models and methods to help reach the ambitious target set by UN SDGs7: universal access to electricity by 2030. Efficient planning of distribution networks is a complex and multivariate task, which is usually split into multiple subproblems to reduce the number of variables. The present work addresses the problem of optimal secondary substation siting, by means of different clustering techniques. In contrast with the majority of approaches found in the literature, which are devoted to the planning of MV grids in already electrified urban areas, this work focuses on greenfield planning in rural areas. K-means algorithm, hierarchical agglomerative clustering, and a method based on optimal weighted tree partitioning are adapted to the problem and run on two real case studies, with different population densities. The algorithms are compared in terms of different indicators useful to assess the feasibility of the solutions found. The algorithms have proven to be effective in addressing some of the crucial aspects of substations siting and to constitute relevant improvements to the classic K-means approach found in the literature. However, it is found that it is very challenging to conjugate an acceptable geographical span of the area served by a single substation with a substation power high enough to justify the installation when the load density is very low. In other words, well known standards adopted in industrialized countries do not fit with developing countries’ requirements.

AbstractPrototypes are an established tool for rapidly increasing learning, communication and decision making rationale for design projects. The proven success has spawned a litany of approaches and methods for building and planning the efficient planning and construction of prototypes. Translating these methods into simple usable tools to assist novice designers has generated broadly applicable canvases to support prototyping across the design process. Product Service System design has similarly introduced prototyping methods and tools into the process. Presently there is a lack of support for generating early phase tangible prototypes for functional PSS design aimed at more radically innovative solutions instead of currently dominant traditional products with traditional add-on services. This work explores the viability of utilizing existing prototyping support tools in the context of early PSS design through workshops with student designers and practitioners. The data from these workshops illuminates the alignments and misalignment gaps presented as guidelines to enable better support for early PSS designers.

The United States Army Research Institute of Environmental Medicine (USARIEM) celebrated its 50th anniversary on July 1, 2011. This article reviews its history, evolution, and transition of its research programs as well as its scientific and military accomplishments, emphasizing the past 25 yr. During the 1990s, USARIEM published a series of pocket guides providing guidance for sustaining Warfighter health and performance in Southwest Asia, Somalia, the former Republic of Yugoslavia, Rwanda, and Haiti. Issues identified during Operation Desert Storm elicited research that improved nutritional guidelines for protracted desert operations; safer use of nuclear, chemical, and biological protective clothing; equipment, development, and fielding of efficient microclimate cooling systems; and effective evaluation of pharmaceuticals to protect soldiers from chemical and biological threats. During the first decade of the 21st century, USARIEM and the Department of the Army published official medical/performance doctrines for operations in the heat and cold and at high altitude. The current Global War on Terrorism focused research to improve doctrines for hot, cold, and high-altitude operations, reduce musculoskeletal training injuries, provide improved field nutrition, more efficient planning for operational water requirements, and improve both military clothing and materiel. This article also describes the critically important interactions and communications between USARIEM and deployed units and the benefits to Warfighters from this association. This report presents USARIEM's unique and world-class facilities, organizational changes, scientific and support personnel, and major research accomplishments, including the publication of 2,200 scientific papers over the past 25 yr.

The Many

The Iraqi reality misses the foundations of good governance in Iraq, as well as the comprehensive development programs that produce economic and financial reforms, especially in the federal budget, which is characterized as a fragile, weak and vocal budget. Therefore, it came as a modest attempt to shed light on the justifications for achieving good and good governance and efficient planning for the federal budget in its expenditures and revenues. The public, which contributes to building the state and achieving sustainable development that helps solve the main community problems, reduce poverty indicators, reduce unemployment, provide housing and basic services for all components of Iraqi society, and one of the doors to good and rational governance is the efficient management of the federal budget in Iraq, which is represented by efficient planning for managing public money. And protecting it from corruption is in addition to the many problems that fiscal policy suffers from, including weak non-oil financial revenues and dependence on oil revenues, and the growing deficit in budget planning and reliance in particular on foreign debt in the face of the deficit, and solutions are not impossible but need a national administration to achieve them.

Insight Into

Abstract Spatial boundaries play an important role in defining spaces, structuring memory and supporting planning during navigation. Recent models of hierarchical route planning use boundaries to plan efficiently first across regions and then within regions. However, it remains unclear which structures (e.g. parks, rivers, major streets, etc.) will form salient boundaries in real-world cities. This study tested licensed London taxi drivers, who are unique in their ability to navigate London flexibly without physical navigation aids. They were asked to indicate streets they considered as boundaries for London districts or dividing areas. It was found that agreement on boundary streets varied considerably, from some boundaries providing almost no consensus to some boundaries consistently noted as boundaries. Examining the properties of the streets revealed that a key factor in the consistent boundaries was the near rectilinear nature of the designated region (e.g. Mayfair and Soho) and the distinctiveness of parks (e.g. Regent's Park). Surprisingly, the River Thames was not consistently considered as a boundary. These findings provide insight into types of environmental features that lead to the perception of explicit boundaries in large-scale urban space. Because route planning models assume that boundaries are used to segregate the space for efficient planning, these results help make predictions of the likely planning demands of different routes in such complex large-scale street networks. Such predictions could be used to highlight information used for navigation guidance applications to enable more efficient hierarchical planning and learning of large-scale environments.
