The separation wall, one of the largest civil engineering projects in Israel's history, has been criticized even by the U.S. administration, with Condoleezza Rice stating at the end of June 2003 that it ““arouses our [U.S.] deep concern”” and President Bush on 25 July calling it ““a problem”” and noting that ““it is very difficult to develop confidence between the Palestinians and Israel with a wall snaking through the West Bank.”” A number of reports have already been issued concerning the wall, including reports by B'Tselem (available at www.btselem.org), the UN Office for the Coordination of Humanitarian Affairs (available at www.palestinianaid.info), and the World Bank's Local Aid Coordination Committee (LACC; also available at www.palestinianaid.info). UNRWA's report focuses on the segment of the wall already completed and is based on field visits to the areas affected by the barriers, with a special emphasis on localities with registered refugees. Notes have been omitted due to space constraints. The full report is available online at www.un.org/unrwa.

AbstractStudying large-scale collaborative systems engineering projects across teams with differing intellectual property clearances, or healthcare solutions where sensitive patient data needs to be partially shared, or similar multi-user information systems over databases, all boils down to a common mathematical framework. Updateable views (lenses) and more generally bidirectional transformations are abstractions to study the challenge of exchanging information between participants with different read access privileges. The view provided to each participant must be different due to access control or other limitations, yet also consistent in a certain sense, to enable collaboration towards common goals. A collaboration system must apply bidirectional synchronization to ensure that after a participant modifies their view, the views of other participants are updated so that they are consistent again. While bidirectional transformations (synchronizations) have been extensively studied, there are new challenges that are unique to the multidirectional case. If complex consistency constraints have to be maintained, synchronizations that work fine in isolation may not compose well. We demonstrate and characterize a failure mode of the emergent behaviour, where a consistency restoration mechanism undoes the work of other participants. On the other end of the spectrum, we study the case where synchronizations work especially well together: we characterize very well-behaved multidirectional transformations, a non-trivial generalization from the bidirectional case. For the former challenge, we introduce a novel concept of controllability, while for the latter one, we propose a novel formal notion of faithful decomposition. Additionally, the paper proposes several novel properties of multidirectional transformations.

This paper presents a review of the existing models for the estimation of explosion-induced crushed and cracked zones. The control of these zones is of utmost importance in the rock explosion design, since it aims at optimizing the fragmentation and, as a result, minimizing the fine grain production and recovery cycle. Moreover, this optimization can reduce the damage beyond the set border and align the excavation plan with the geometric design. The models are categorized into three groups based on the approach, i.e., analytical, numerical, and experimental approaches, and for each group, the relevant studies are classified and presented in a comprehensive manner. More specifically, in the analytical methods, the assumptions and results are described and discussed in order to provide a useful reference to judge the applicability of each model. Considering the numerical models, all commonly-used algorithms along with the simulation details and the influential parameters are reported and discussed. Finally, considering the experimental models, the emphasis is given here on presenting the most practical and widely employed laboratory models. The empirical equations derived from the models and their applications are examined in detail. In the Discussion section, the most common methods are selected and used to estimate the damage size of 13 case study problems. The results are then utilized to compare the accuracy and applicability of each selected method. Furthermore, the probabilistic analysis of the explosion-induced failure is reviewed using several structural reliability models. The selection, classification, and discussion of the models presented in this paper can be used as a reference in real engineering projects.

Increasing traffic volume and insufficient road lanes often require municipal roads to be reconstructed and expanded. Where a road passes under a bridge, the reconstruction and expansion project will inevitably have an impact on the bridge. To evaluate the safety impact of road engineering projects on bridges, this paper evaluates the safety of the roads and ancillary facilities of highway bridges involved in municipal road engineering projects. Based on a comprehensive analysis of the safety factors of municipal roads undercrossing existing bridges, a fuzzy comprehensive analytic hierarchy process (AHP) evaluation method for the influence of road construction on the safety of existing bridges is proposed. First, AHP is used to select 11 evaluation factors. Second, the target layer, criterion layer, and index layer of evaluation factors are established, then a safety evaluation factor system is formed. The three-scale AHP model is used to determine the weight of assessment indexes. Third, through the fuzzy comprehensive AHP evaluation model, the fuzzy hierarchical comprehensive evaluation is carried out for the safety assessment index system. Finally, the fuzzy comprehensive evaluation method is applied to the engineering example of a municipal road undercrossing an existing expressway bridge. The comprehensive safety evaluation of the existing bridge reflects the practicability and feasibility of the method. It is expected that, with further development, the method will improve the decision-making process in bridge safety assessment systems.

AbstractIt is largely assumed that conceptual engineering is essentially about revising, introducing, or eliminating representational devices, in particular the intension and extension of words and concepts. However, tying conceptual engineering too closely to representations is risky. Not everyone endorses the notion of representation as theoretically helpful or even real. Not everyone thinks that concepts or meanings should be understood in terms of the notion of representation. Does this mean that conceptual engineering is not interesting or relevant for these skeptics? In this paper, I motivate and propose a non-representationalist construal of conceptual engineering. I argue that conceptual engineers can be understood as primarily engineering linguistic entitlements and commitments rather than representational devices. Note that this account is non-representationalist, but explicitly not anti-representationalist. Representations may play a significant role when it comes to justifying and completing commitment engineering projects.

Purpose Despite the advent of sophisticated control methods, there are still significant issues regarding late delivery of information technology projects. The purpose of this paper is to investigate the common causes of scheduling problems specifically in the information technology projects context. Design/methodology/approach Through a quantitative research, the importance of those causes, as well as the underpinning factors driving them, is explored. The causes are ranked according to their relative important index, and exploratory factor analysis is employed to reveal underlying dimensions (factors) of these causes. Findings From the analysis, four factors were extracted, namely, “Dataless Newbie,” “Technical Newbie,” “Pragmatic Futurist” and “Optimistic Politician.” These factors explain the different latent conditions that lead to scheduling problems in information technology projects. Practical implications The key contribution of this research is that it enlightens the latent conditions underpinning scheduling problems. Also, the evidence provides that schedule development for information technology projects is impacted by the same causes that impact engineering projects, and that applying a number of mitigation techniques widely used within the engineering area, such as reference class, would, no doubt, not only improve information technology schedules but also reduce the political pressures on the project manager. Originality/value This research provides a valuable insight into understanding the underlying factors for poor project estimation.
