Evidence of early tobacco in Northeastern North America?

While tobacco use was a widespread and important social practice among Native Americans during the Historic Period, the prehistoric origins of the practice are poorly understood. Smoking pipes significantly predate botanical evidence of tobacco in Eastern North America. A promising technique for addressing this problem is gas chromatography/mass spectroscopy (GC/MS) analysis to identify nicotine or related compounds in smoking pipe residues. GC/MS analysis of a smoking pipe dating to approximately 300 B.C. from the Boucher Site, a Middlesex-complex site from Vermont, has produced evidence of nicotine decay products. This is interpreted as evidence for an Early Woodland Period origin for tobacco use in Eastern North America. The cultural and chronological implications of this finding are discussed.     

Best practices for measuring community resources across Canada: A comparison of coding classifications

Social scientists, geographers, criminologists, and health scientists are often tasked with finding data to best capture the impact of “community context” on individual outcomes, including residential services, physical resources, and social institutions. One outlet for such data in Canada is Digital Map Technologies Inc. (DMTI) Spatial, which offers a national repository of over one million businesses and recreational points of interest. The database is generated through CanMap Streetfiles, which includes geocodes of each point's precise location. These data are available to researchers from their university data library and Esri Canada, but primarily available to private sector and government markets. That said, the goal of the current paper is to encourage researchers to access this rich yet under-utilized data source. Each service, business, or resource in the DMTI Spatial database is assigned to a respective category using Standard Industrial Classification codes and North American Industrial Classification System codes. It is not clear, however, which is the more reliable coding criteria. We provide an overview of our review of DMTI Spatial data and take-away suggestions for using this valuable resource for future research on meso-level residential markers.     

The Index of Economic Disparity: Measuring trends in economic disparity across Canadian Census Subdivisions and rural and urban communities

Territorial inequalities have long been a subject of study and concern in Canada. In the face of large structural changes such as industrial shifts and the decarbonization of our economies, there is an urgency to understand such inequalities and design effective policy interventions for those places facing persistent economic decline. This paper shares a novel composite index that measures economic disparity across Canadian Census Subdivisions (CSDs) using Census data from 2001 through 2016 and the 2011 National Household Survey. Named the “Index of Economic Disparity,” it is comprised of an equally weighted average of four sub-indices that assign percentile rankings for all CSDs based on whether they experience persistent and substantial decline in key economic areas: population, labour force outcomes, working-age share of population, and industrial diversity. The variation of outcomes across geographies—urban and rural—highlights the importance of place-based policies.     

Deterrence Theory and the Implementation of Speed Limits in the American States

Despite the ubiquitous nature of these policies, there is disagreement in the literature regarding the direction and size of the impact that speed limits have on traffic‐related fatalities. We argue in this paper that the mixed results in previous work may arise because these studies have missed an important component of the implementation of speed limit laws. More explicitly, they have failed to adequately control for the deterrent effect of enforcement and sanctions. We develop the argument that the observed impacts of speed limits will be overly large when the certainty and severity of punishment are not accounted for. We test this assertion in a cross‐sectional time series analysis of state‐level traffic fatalities from the years 1990–2006 and find that lower speeds do save a significant number of lives. Interestingly, we find that the impact is significantly overestimated for 65‐mph limits and significantly underestimated for 70‐mph limits when enforcement, penalties, and the interaction of the two are excluded. The results also suggest that fines have a rather modest impact on fatalities unless states employ a sufficient number of troopers to enforce posted limits. In addition to clarifying previous findings related to speed limit policy, therefore, the findings contribute to the general application of deterrence theory by empirically confirming that the importance of sanction severity is dependent on the perceived certainty of punishment.
