Containing Violence in El Salvador: Community Organization,Transnational Networks and State–Society Relations

Extant research has analysed the impact of security policies, truces and informal agreements on both the dynamics and traits of organized violence in El Salvador. However, less is understood about variation in the levels of lethal violence across subnational units. This article contributes to filling this gap. Based on a case study of the municipality of Chalatenango, the analysis shows that community organization and translocal dynamics are crucial to explaining violence containment. Local communities have managed to control the levels of lethal violence and deter criminal actors amid a national context characterized by state neglect and chronic violence. Community organization is not territorially bound but extends across transnational networks. Migrants are a source of livelihoods for the local population; they also contribute to providing public goods and participate in local forms of organization. Transnational networks have forged a migration corridor that enables immigration to the United States. In addition, community organization informally contributes to the capacity of the local state to perform its functions, thereby shaping cooperative state–society relations. This analysis sheds new light on the conditions shaping the variation in levels of violence at the subnational level and local governance dynamics.     

The 1561 Earthquake(s) in Southern Italy: New Insights into a Complex Seismic Sequence

In the summer of 1561, a strong seismic sequence struck southern Italy, then the Spanish-ruled Kingdom of Naples. Both the Italian seismological tradition and the latest catalogues locate it in the Vallo di Diano (Diano Valley), a low-seismicity intermontane basin 100 km south-east of Naples. We explore the hypothesis that current perception of the 1561 earthquake is distorted by the nature of the historical dataset from which its parameters have been assessed, and which mostly derive from a single—albeit very detailed—primary source. We present and discuss several previously unconsidered original accounts. Our results cast doubts on the traditional interpretation of the earthquake, which could have been either one Vallo di Diano mainshock or several strong earthquakes within a time/space window compact enough for contemporary viewers to perceive them as one. Unquestionably, there is much more to the 1561 earthquake(s) than previously appeared. We hope that this groundbreaking effort will rekindle the interest of the seismological community in this seismic episode, our knowledge of which is still far from complete.     

Patterns of Cranial Trauma in a Prehistoric Population from Central California

Evidence of cranial trauma was investigated in a skeletal sample from the site CA-Ala-329 located on the eastern side of San Francisco Bay, Central California. The sample included 365 crania, including 134 adult males, 104 adult females, 22 adults of indeterminate sex and 105 subadults. Evidence of cranio-facial fracture was found in eight individuals, one of whom is an adolescent. Thus, the frequency in adult crania of traumatic injury is 7/260 (2.7 per cent). Of the seven individuals of known sex displaying such cranial trauma, all are male. The injuries are generally suggestive of some form of interpersonal aggression, with five healed vault fractures, one lesion with an embedded obsidian fragment (a probable projectile point) and two healed facial fractures. Further clear evidence of interpersonal aggression has been previously determined in this sample and has been reported at even higher levels elsewhere in California. © 1997 by John Wiley & Sons, Ltd.

Reconstructing Archaeological Networks with Structural Holes

Model-based reconstruction is an approach to infer network structures where they cannot be observed. For archaeological networks, several models based on assumptions concerning distance among sites, site size, or costs and benefits have been proposed to infer missing ties. Since these assumptions are formulated at a dyadic level, they do not provide means to express dependencies among ties and therefore include less plausible network scenarios. In this paper we investigate the use of network models that explicitly incorporate tie dependence. In particular, we consider exponential random graph models, and show how they can be applied to reconstruct networks coherent with Burt's arguments on closure and structural holes (Burt 2001). The approach is illustrated on data from the Middle Bronze Age in the Aegean.     

The impact of long-distance commuting on salaries and employment in host regions in Chile

Long-distance commuting (LDC) is an increasingly relevant strategy of labor mobility worldwide and is therefore key to understanding the structure and dynamics of labor markets. However, little is known about the effect that LDC has on the labor market equilibrium of host territories. This paper addresses this gap for the case of Chile. While LDC is a useful strategy for improving salary and employment on a national scale, our results show a negative effect for residents in host territories (on a local scale), particularly when LDC results in commuters with similar characteristics to residents competing for the same jobs.
