    During the period August 6-27, and November 18-20, 2003, archeologists from Geo-Marine Inc. (GMI), of Plano, Texas, conducted a pedestrian survey of a 51.5 km-long corridor for the proposed Southside Regional Water System in Marion, Harrison, Upshur, and Gregg counties, Texas. The proposed waterline is intended to draw water from Lake O The Pines in the Big Cypress drainage system and distribute it to various communities in both the Big Cypress and Little Cypress Creek basins in the aforementioned counties. Specifically, the pipeline will benefit the communities of Ore City, Old Diana, Diana, and James before the pipeline crosses Little Cypress Creek and winds southeastward to a booster pump station for further distribution to other communities through existing pipelines. During the survey, random shovel testing near the community of James found an isolated, expended chipped stone grubbing implement made of gray siltstone. Due to the scarcity of such tools, and the desire to call attention to the locus of this unusual item, the State Historic Preservation Office suggested that GMI assign the location an archeological site number, rather than retain it as an isolated occurrence. The purpose of this brief note is to discuss the find location, describe this relatively unusual artifact, and draw comparisons with similar implements

    A Social Network Perspective on Envy in Organizations

    This chapter seeks to examine the development and consequences of envy using a social networks perspective. The social network perspective considers that individuals are embedded in a web of relationships which significantly influence individual behavior (Borgatti, Mehra, Brass, & Labianca, 2009). Much of the activity that takes place inside an organization occurs within a structure of informal relationships. These relationships, although informal, often represent key communication-based interactions that allow employees to do their jobs. People often compare their levels of performance and awards attained to those of their coworkers. They gather this social comparison information through direct inquiry and third-party gossip. We argue that the content and structure of informal relationships will affect people’s access to and interpretation of social comparison information. We examine dyadic implications of social networks on the development and consequences of envy, such as the bonds that exist between potential enviers and the targets of their envy, the type and strength of the relationships and the frequency of interaction between the dyads. We also explore implications beyond the dyad - which can only be understood by considering the overall network structure in which employees are embedded - such as how the overall network structure creates a context within which interactions take place, how the relative positions of a potential envier and the target of envy within the network structure and their respective individual network characteristics impact the likelihood of comparison and the development of envy, and how the cognitions that employees have about workplace networks affect social comparison and the development of envy. Our goal is to open up a discussion about how social networks within organizations influence 1) social comparison processes, 2) the development of envy and the form it takes, and 3) the consequences of envy, with a specific focus on the behavior of the envier. Our hope is to inspire both envy researchers and social networks researchers to consider conducting empirical research at the intersection of social networks and envy, with the goal of improving our understanding of both

    Economic benefit of tuberculosis control

    Tuberculosis is the most important infectious cause of adult deaths after HIV/AIDS in low- and middle-income countries. This paper evaluates the economic benefits of extending the World Health Organization's DOTS Strategy (a multi-component approach that includes directly observed treatment, short course chemotherapy and several other components) as proposed in the Global Plan to Stop TB, 2006-2015. The authors use a model-based approach that combines epidemiological projections of averted mortality and economic benefits measured using value of statistical life for the Sub-Saharan Africa region and the 22 high-burden, tuberculosis-endemic countries in the world. The analysis finds that the economic benefits between 2006 and 2015 of sustaining DOTS at current levels relative to having no DOTS coverage are significantly greater than the costs in the 22 high-burden, tuberculosis-endemic countries and the Africa region. The marginal benefits of implementing the Global Plan to Stop TB relative to a no-DOTS scenario exceed the marginal costs by a factor of 15 in the 22 high-burden endemic countries, a factor of 9 (95% CI, 8-9) in the Africa region, and a factor of 9 (95% CI, 9-10) in the nine high-burden African countries. Uncertainty analysis shows that benefit-cost ratios of the Global Plan strategy relative to sustained DOTS were unambiguously greater than one in all nine high-burden countries in Africa and in Afghanistan, Pakistan, and Russia. Although HIV curtails the effect of the tuberculosis programs by lowering the life expectancy of those receiving treatment, the benefits of the Global Plan are greatest in African countries with high levels of HIV.Health Monitoring&Evaluation,Disease Control&Prevention,Population Policies,Health Systems Development&Reform,Poverty and Health
