Sidelining the Hardliners: A 2 + 1 Solution for Israel‐Palestine

This article presents a modified two‐state solution to the Israeli‐Palestinian conflict. A “2 + 1 solution” would see the establishment of a State of Palestine in the West Bank whose constitution proscribes the participation in government of any party whose platform calls for the elimination of Israel; Gaza would accede upon the reform or demise of Hamas. Achieving a state in the West Bank should be the proximate, urgent goal of the Palestinian people. Ideologically motivated Israeli settlement of the West Bank continues apace and threatens the viability of a two‐state solution. Meanwhile, religiously motivated policies of colonization hide behind a security narrative conflating Hamas with Fatah and suggesting that the Palestinians pose an existential threat. The 2 + 1 solution, by excluding Hamas from a State of Palestine, directly addresses Israel's legitimate security concerns and thus carries the potential to lay bare the extent to which ideology informs Israeli policy. The approach also gives moderate Palestinians the opportunity to define the civic values and attributes of Palestinian national identity in a way that supports a lasting two‐state peace.     

An Improved Displacement-Based Adaptive Pushover Procedure for the Analysis of Frame Buildings

The main purpose of this article is to develop an alternative adaptive pushover method in which multiple inelastic response spectra proportional to the instantaneous ductility ratio of the structure are employed to reflect the actual energy dissipation characteristic of the structure at a given deformation level. Based on the proposed methodology, two load patterns are independently applied to the structure and the envelope of the demand values is computed. The obtained results demonstrate that the proposed method provides improved predictions of the peak interstory and total drift profiles of the structure.     

Predictive Tri-Linear Benchmark Curve for In-Plane Behavior of Adobe Walls

In the present study, numerical simulations are conducted to estimate the in-plane response of adobe walls subjected to pseudo-static cyclic loading based on the finite element code ABAQUS. The simplified micro-modeling approach is adopted and an interface model reported in ABAQUS material library is applied as material model for zero-thickness interface elements. The comparison between obtained results and field test data results in good agreement. Parametric studies are carried out to evaluate the effectiveness of independent parameters changes on response of adobe walls. It is noted that mechanical properties of joints and adobe units play an active role on in-plane behavior of walls. A tri-linear benchmark curve is proposed to predict the response of aforementioned walls. In this regard, a statistical study is performed to derive the predictive tri-linear benchmark curve. The regressive analysis on 59 numerical models resulted in proposing predictive models. Finally, by comparing tri-linear curves obtained from the regressive analysis, numerical analysis, and experimental study, appropriate accuracy of theoretical model can be found.     

Multi‐Domain User‐Generated Content Based Model to Enrich Road Network Data for Multi‐Criteria Route Planning

By utilizing today's web‐based technologies, people can act as sensors and share their perceptions, emotions and observations in a variety of data forms, such as images, videos, texts, Global Positioning System (GPS) trajectories and maps. These forms are collectively called user‐generated content (UGC). These data are in different domains and have a multi‐modality nature. Although recent efforts have probed the acquisition of local knowledge by using single‐domain UGC data in specific applications, such efforts have not thus far presented a model considering multi‐domain UGC specifically to enrich road network data. This article aims at presenting such a model wherein, with the help of each data domain of UGC, one aspect of people knowledge about the road segment is obtained. These different aspects of knowledge are integrated using a Skyline operator to support multi‐criteria route finding. We name this model ERSBU (enriching road segments based on UGC). In ERSBU, road segments are basic spatial units, and their subjective properties have been extracted by using available UGC. The scenic score for each road segment was computed by using geo‐tagged Panoramio photos. The accessibility level of each road segment to different facilities was calculated based on data captured from Wikimapia and OpenStreetMap. Moreover, for measuring the movement popularity of each road segment, Wikiloc and Everytrail GPS trajectories were utilized. For the implementation of the ERSBU model, Tehran region 6 was considered the case study area. The Evaluation of the results proved that road segments that achieved a high score based on knowledge extracted from UGC also mostly gained top scores by analyzing traditional maps. ERSBU allows users to accomplish more‐qualitative path finding by considering the multi‐view characteristics of road segments.     

Terror or Terrorism? The “Islamic State” Between State and Nonstate Violence

As a non‐state actor that claims its own territory, the “Islamic State” utilizes a spectrum of very different kinds of coercion and violence. Considering the group's aspirations to govern the territories controlled by it, any clear distinction between uses of force and coercion that states typically claim as their legitimate right, and implement terrorist non‐state violence, tends to blur right before our analytically‐focused eyes. This contribution discusses how the group challenges the distinction between “terror from above” and “terrorism from below” as well as the meaning of the dual character of Daesh's belief system between the ideological and the religious for Daesh's repertoire of violence.
