Abstract. During a disaster, the activity of the crowd represents a very valuable source of the on-the-ground conditions shared by the affected citizens. The approach, presented in the paper, explores the relationship between the spatial distribution of crowdsourced image posts and damaged buildings in order to understand the potential of modelling the spatial distribution of damaged buildings based on geolocated images. The posts related to the hurricane Michael that happened in the United States in October 2018, showing the building damage of Panama City, have been collected by NAPSG Foundation and GISCorps volunteers. The building damage assessment, based on the analysis of high-resolution post-event imagery, has been performed by FEMA. Exploring the two available independent point datasets, the spatial pattern of each individual dataset has been analysed and furthermore the spatial relationship between them has been explored. A set of spatial statistics has been performed with R software. For this purpose, the distance-based methods have been used, that consider the mutual position of points to describe the patterns. The results shown the spatial relationship between the crowdsourced photos and different damage types. Furthermore, potential of crowdsourced images for improving the awareness of the structural damage after the hurricane have been discussed.

Abstract. Just 4 days after the M = 7.1 earthquake on 12 January 2010, Haitians could send SMS messages about their location and urgent needs through the on-line mapping platform Ushahidi. This real-time crowdsourcing of crisis information provided direct support to key humanitarian resources on the ground, including Search and Rescue teams. In addition to its use as a knowledge base for rescue operations and aid provision, the spatial distribution of geolocated SMS messages may represent an early indicator on the spatial distribution and on the intensity of building damage. This work explores the relationship between the spatial patterns of SMS messages and building damage. The latter is derived from the detailed damage assessment of individual buildings interpreted in post-earthquake airborne photos. The interaction between SMS messages and building damage is studied by analyzing the spatial structure of the corresponding bivariate patterns. The analysis is performed through the implementation of cross Ripley's K-function which is suitable for characterizing the spatial structure of a bivariate pattern, and more precisely the spatial relationship between two types of point sets located in the same study area. The results show a strong attraction between the patterns exhibited by SMS messages and building damages. The interactions identified between the two patterns suggest that the geolocated SMS can be used as early indicators of the spatial distribution of building damage pattern. Accordingly, a statistical model has been developed to map the distribution of building damage from the geolocated SMS pattern. The study presented in this paper is the first attempt to derive quantitative estimates on the spatial patterns of novel crowdsourced information and correlate these to established methods in damage assessment using remote sensing data. The consequences of the study findings for rapid damage detection in post-emergency contexts are discussed.

The Relationship

While research has found that millions of children in the United States are exposed to their mothers being battered, and that many are themselves abused as well, little is known about the ways in which children are used by abusers to manipulate or harm their mothers. Anecdotal evidence suggests that perpetrators use children in a variety of ways to control and harm women; however, no studies to date have empirically examined the extent of this occurring. Therefore, the current study examined the extent to which survivors of abuse experienced this, as well as the conditions under which it occurred. Interviews were conducted with 156 women who had experienced recent intimate partner violence. Each of these women had at least one child between the ages of 5 and 12. Most women (88%) reported that their assailants had used their children against them in varying ways. Multiple variables were found to be related to this occurring, including the relationship between the assailant and the children, the extent of physical and emotional abuse used by the abuser against the woman, and the assailant's court-ordered visitation status. Findings point toward the complex situational conditions by which assailants use the children of their partners or ex-partners to continue the abuse, and the need for a great deal more research in this area.

The Relationship

The United States, Iran and the Bomb provides the first comprehensive analysis of the US-Iranian nuclear relationship from its origins through to the signing of the Joint Comprehensive Plan of Action (JCPOA) in 2015. Starting with the Nixon administration in the 1970s, it analyses the policies of successive US administrations toward the Iranian nuclear programme. Emphasizing the centrality of domestic politics to decision-making on both sides, it offers both an explanation of the evolution of the relationship and a critique of successive US administrations' efforts to halt the Iranian nuclear programme, with neither coercive measures nor inducements effectively applied. The book further argues that factional politics inside Iran played a crucial role in Iranian nuclear decision-making and that American policy tended to reinforce the position of Iranian hardliners and undermine that of those who were prepared to compromise on the nuclear issue. In the final chapter it demonstrates how President Obama's alterations to American strategy, accompanied by shifts in Iranian domestic politics, finally brought about the signing of the JCPOA in 2015.

The New Deal

De forma un tanto paradójica, a finales de los años treinta, las relaciones entre México y Estados Unidos sufrieron uno de los momentos de máxima tensión, para pasar, a continuación, a experimentar una notable mejoría, alcanzando el cénit en la alianza política y militar sellada durante la Segunda Guerra Mundial. El episodio catalizador de la tensión y posterior reconciliación fue, sin duda, el conflicto diplomático planteado tras la nacionalización petrolera de 1938. De entre los factores que propiciaron la solución pacífica y negociada al conflicto petrolero, el presente artículo se centra en analizar dos fenómenos del momento. En primer lugar, siguiendo un orden de relevancia, se examina el papel que tuvo la Guerra Civil Española. Aunque las posturas de ambos gobiernos ante el conflicto español fueron sustancialmente distintas, las interpretaciones y las lecciones sobre sus posibles consecuencias permitieron un mayor entendimiento entre los dos países vecinos. En segundo lugar, también se analizarán las afinidades ideológicas entre el New Deal y el cardenismo en el contexto de la crisis mundial económica y política de los años treinta, con el fin de entender su papel lubricante en las relaciones bilaterales de la época. Somewhat paradoxically, at the end of the 1930s, the relationship between Mexico and the United States experienced one of its tensest moments, after which it dramatically improved, reaching its zenith in the political and military alliance cemented during World War II. The catalyst for this tension and subsequent reconciliation was, without doubt, the diplomatic conflict that arose after the oil nationalization of 1938. Of the various factors that led to a peaceful negotiated solution to the oil conflict, this article focuses on analyzing two phenomena. Firstly—in order of importance—this article examines the role that the Spanish Civil War played. Although the positions of both governments in relation to the Spanish war were significantly different, the interpretations and lessons concerning potential consequences enabled a greater understanding between the two neighboring countries. Secondly, this article also analyzes the ideological affinities between the New Deal and Cardenismo in the context of the global economic and political crisis of the thirties, seeking to understand their role in facilitating bilateral relations during that period.

Freedom Struggles

George Floyd’s murder by police on 26 May 2020 set off a cycle of struggle that was notable for its size, intensity, and rate of diffusion. Starting in Minneapolis, the uprising quickly spread to dozens of other major cities and brought with it a repertoire that included riots, arson, and looting. In many places, these tactics coexisted with more familiar actions like public assemblies and mass marches; however, the inflection these tactics gave to the cycle of contention is not easily reconciled with the protest repertoire most frequently mobilized during movement campaigns in the United States today. This discrepancy has led to extensive commentary by scholars and movement participants, who have often weighed in by considering the moral and strategic efficacy of the chosen tactics. Such considerations should not be discounted. Nevertheless, I argue that both the dynamics of contention witnessed during the uprising and their ambivalent relationship to the established protest repertoire must first be understood in historical terms. By considering the relationship between violence, social movements, and Black freedom struggles in this way, I argue that scholars can develop a better understanding of current events while anticipating how the dynamics of contention are likely to develop going forward. Being attentive to these dynamics should in turn inform our research agendas, and it is with this aim in mind that I offer the following ten theses.

In the first half of the 19th century scientific philosophers in the United States, such as Emerson and Thoreau, began to pursue the relationship between man and nature. Painters from the Hudson River School discovered the rural spaces to the north of New York and began to celebrate the American landscape in their paintings. In many places at this time garden societies were founded, which generated widespread support for the creation of park enclosures While the first such were cemeteries with the character of parks, housing developments on the peripheries of towns were later set in generous park landscapes. However, the centres of the growing American cities also need green spaces and the so-called «park movement»reached a first high point with New York's Central Park. It was not only an experimental field for modern urban elements, but even today is a force of social cohesion.

The Relationship

This essay explores the evolving international relationship of the two national park agencies that in 1968 began to offer joint training classes for protected-area managers from around the world. Within the British settler societies that dominated nineteenth century park-making, the United States’ National Park Service (NPS) and Canada’s National Parks Branch were the most closely linked and most frequently cooperative. Contrary to campfire myths and nationalist narratives, however, the relationship was not a one-way flow of information and motivation from the US to Canada. Indeed, the latter boasted a park bureaucracy before the NPS was established. The relationship of the two nations’ park leaders in the half century leading up to 1968 demonstrates the complexity of defining the influences on park management and its diffusion from one country to another.
