Compare And Contrast

An important and underexamined topic in the growing literature on community-embedded organizing concerns situations in which dramatic shifts in the environment require the time-sensitive re-establishment of both communities and organizations to address urgent needs. We conduct a qualitative study of emergent community-organization trajectories in the aftermath of the 2010 Haiti earthquake and explore differences in the processes and interactions between emerging organizations and communities. Despite all organizations in our data facing the same external shock, they differed in how they interpreted the nature of crisis-induced voids, established boundaries to build and organize communities, and created connections to bind themselves to their communities. We compare and contrast these differences to reveal three trajectories of community-organization emergence, explain why these trajectories initially formed in the ways they did, and identify unique mechanisms that led to these trajectories’ divergence. Our findings contribute to the literature on community-embedded organizing by demonstrating how organizations re-establish communities while simultaneously emerging within those communities.

Abstract. This paper examines the ionospheric anomalies around the time of a strong earthquake (M = 7.0) which occurred in Haiti region (18.457° N, 72.533° W) on 12 January 2010. DEMETER satellite data have been used to study the plasma parameters variation during the Haiti earthquake. One day (11 January 2010) before the earthquake there is a significant enhancement of electron density and electron temperature near the epicenter. Decrease of electron temperature is observed few days after the earthquake. Anomalous plasma parameter variations are detected both in day and nighttimes before the quake. Statistical processing of the DEMETER data demonstrates that satellite data can play an important role for the study of precursory phenomena associated with earthquakes.

The Cost

Earthquake is one of the most devastating natural disasters that threaten human life. It is vital to retrieve the building damage status for planning rescue and reconstruction after an earthquake. In cases when the number of completely collapsed buildings is far less than intact or less-affected buildings (e.g., the 2010 Haiti earthquake), it is difficult for the classifier to learn the minority class samples, due to the imbalance learning problem. In this study, the convolutional neural network (CNN) was utilized to identify collapsed buildings from post-event satellite imagery with the proposed workflow. Producer accuracy (PA), user accuracy (UA), overall accuracy (OA), and Kappa were used as evaluation metrics. To overcome the imbalance problem, random over-sampling, random under-sampling, and cost-sensitive methods were tested on selected test A and test B regions. The results demonstrated that the building collapsed information can be retrieved by using post-event imagery. SqueezeNet performed well in classifying collapsed and non-collapsed buildings, and achieved an average OA of 78.6% for the two test regions. After balancing steps, the average Kappa value was improved from 41.6% to 44.8% with the cost-sensitive approach. Moreover, the cost-sensitive method showed a better performance on discriminating collapsed buildings, with a PA value of 51.2% for test A and 61.1% for test B. Therefore, a suitable balancing method should be considered when facing imbalance dataset to retrieve the distribution of collapsed buildings.
