Livability efforts in St Louis might benefit from recruiting additional for-profit partners that provide the network with new perspectives and needed resources, and from cultivating positive partnerships with government organizations that can assist with local policy development and enforcement.

Tobacco product displays are a pervasive presence in convenience stores, supermarkets, pharmacies, and other retailers nationwide. The influence that tobacco product displays have on purchases and tobacco product initiation, particularly on young people and other vulnerable populations, is well known. An objective measurement tool that is valid, reliable, and feasible to use is needed to assess product displays in the retail setting. This study reports on the relative accuracy of various tools that measure area and/or distance in photos and thus could be applied to product displays. We compare results of repeated trials using five tools. Three tools are smartphone apps that measure objects in photos taken on the device; these are narrowed down from a list of 284 candidate apps. Another tool uses photos taken with any device and calculates relative area via a built-in function in the Microsoft Office Suite. The fifth uses photos taken with the Narrative Clip, a “life-logging” wearable camera. To evaluate validity and reliability, we assess each instrument's measurements and calculate intra-class correlation coefficients. Mean differences between observed measurements (via tape measure) and those from the five tools range from just over one square foot to just over two square feet. Most instruments produce reliable estimates though some are sensitive to the size of the display. Results of this study indicate need for future research to test innovative measurement tools. This paper also solicits further discussion on how best to transform anecdotal knowledge of product displays as targeted and disproportionate marketing tactics into a scientific evidence base for public policy change.

The main aims of this article are threefold. It initially seeks to address two popular misconceptions frequently found in crusade histories and general histories of the Byzantine empire concerning the Turkish invasion and settlement of western Anatolia after the battle of Mantzikert in 1071. The article maintains that blurring the distinctions between the Seljuk Turks of R u m and the tribes of pastoral nomads or rather transhumants who came to be known as Türkmens or Turcomans is incorrect. The oft-repeated assumption that the Seljuk Turks of Baghdad oversaw the Turkish conquest of Anatolia is addressed when tracing the unstructured nature of the Turkish migration and the subsequent lack of unity amongst the invaders. After providing the context of the Turkish settlement in western Anatolia, the article throws new light on the relative ease with which the armies of the First Crusade traversed the Anatolian plateau and Byzantine forces compelled the speedy capitulation of Turkish towns and territories along the western coastal plains and river valleys of Anatolia in 1097 and 1098 respectively.
