The Organization of Novaculite Tool Production: Quarry-Workshop Debitage Comparisons

Arkansas novaculite, outcropping in the Ouachita Mountains of Arkansas and Oklahoma, has been an important regional lithic resource for thousands of years. Because of the stone’s durability, by-products of past novaculite procurement and tool production and use activities litter the landscape in southwest Arkansas. Recent work situates novaculite quarries in the broader context of tool production and exchange systems. This article focuses on the organization of tool production, and explores analytical techniques that can be used to identify spatial separation of the lithic reduction process between quarry, workshop, and habitation sites

Effects of cyclic adenosine 3,5-monophosphate on photoreceptor disc shedding and retinomotor movement. Inhibition of rod shedding and stimulation of cone elongation.

As a test of the hypothesis that cyclic nucleotides play a role in the regulation of retinomotor movements and disc shedding in the photoreceptor-pigment epithelial complex, we have used an in vitro eyecup preparation that sustains both disc shedding and cone retinomotor movements, Eyecups were prepared in white light from animals in which both shedding and cone movement had been blocked by 4 d of constant-light treatment. In eyecups incubated for 3 h in light, disc shedding was negligible and cones remained in the light-adapted (contracted) position. In eyecups incubated in darkness, however, a massive shedding response (dominated by rod photoreceptors) was induced, and at the same time cone photoreceptors elongated to their dark-adapted position. In eyecups incubated in light dbcAMP promoted cone elongation and thus mimicked darkness; the dbcAMP effect was potentiated by the phosphodiesterase inhibitors papaverine and 3-isobutylmethylxanthine. In eyecups incubated in darkness, on the other hand, both phosphodiesterase inhibitors and dbcAMP reduced the phagosome content of the pigment epithelium. The effects of dbcAMP on the cone elongation and rod shedding appear to be specific in that dbcGMP, adenosine, and adenosine 5-monophosphate had no significant effect. Our results suggest that cAMP plays a role in the regulation of both retinomotor movements and disc shedding

The Dynamic Impact of Periodic Review on Women’s Rights

Human rights treaty bodies have been frequently criticized as useless and the regime’s self-reporting procedure widely viewed as a whitewash. Yet very little research explores what, if any, influence this periodic review process has on governments’ implementation of and compliance with treaty obligations. We argue oversight committees may play an important role in improving rights on the ground by providing information for international and primarily domestic audiences. This paper examines the cumulative effects on women’s rights of self-reporting and oversight review, using original data on the history of state reporting to and review by the Committee on the Elimination of Discrimination against Women (CmEDAW). Using a dynamic approach to study the effects of the periodic review process, we find that self-reporting has a significant positive effect on women’s rights. We explore three clusters of evidence for the domestic mobilization mechanism: information provision through domestic civil society organizations; publicity and critique through the domestic media; and parliamentary attention, debate, and implementation of recommendations. This is the first study to present positive evidence on the effects of self-reporting on rights and to describe the mechanisms that link Geneva bodies with local politics. Our findings challenge the received wisdom that the process of reporting to these treaty bodies is basically useless

Using the ICF and psychological models of behavior to predict mobility limitations

Aims to test the ability of a model that integrates the theory of planned behavior (TPB) into the International Classification of Functioning Disability and Health (ICF) to predict walking limitations in adults awaiting hip or knee replacement surgery. Study Design and Participants: Cross-sectional structural equation modeling study of activity limitations in 190 adults. Method: A postal questionnaire measuring the TPB, ICF and walking limitations. Results: The integrated model accounted for more variance in activity limitations (57%) than either the TPB or ICF alone. Control beliefs (TPB) significantly mediated the relationship between impairment (ICF) and activity limitations. Conclusions: The integrated model provides an interdisciplinary theoretical framework that identifies intervention targets to effect reductions in disability without the need for concomitant reductions in impairment

Evaluation of Disability Employment Policy Demonstration Programs

[Excerpt] Since 2001, the Office of Disability Employment Policy (ODEP) has awarded more than $65 million in grants, contracts, and cooperative agreements. Of this, more than$38 million has been awarded to projects under the ODEP Demonstration Program, with about 2 percent directed toward an independent evaluation. The ODEP Demonstration Program consists of a variety of initiatives targeted at both adults and youth with disabilities. All demonstration projects funded under these initiatives are expected to implement and evaluate methods for building the capacity of the workforce development system to better serve people with disabilities. ODEP contracted with Westat, a private research company, to conduct an independent evaluation of its demonstration program. The purpose of the independent evaluation is to provide ODEP with data and information about system change that can be used to assist policy development, decisions, and recommendations, as well as track progress in meeting ODEP’s goals under the Government Performance and Results Act (GPRA). The independent evaluation has three objectives: 1. To provide ODEP with reliable and valid indicators of program effectiveness; 2. To determine the extent to which each program priority area is effective in building workforce development system capacity; and 3. To document local, regional, and/or state systems change that supports program effectiveness. This paper summarizes the issues and accomplishments identified by the evaluation to date in the context of these three objectives

"Whose data is it anyway?" The implications of putting small area-level health and social data online

International audienceThe planetary exospheres are poorly known in their outer parts, since the neutral densities are low compared with the instruments detection capabilities. The exospheric models are thus often the main source of information at such high altitudes. We present a new way to take into account analytically the additional effect of the radiation pressure on planetary exospheres. In a series of papers, we present with an Hamiltonian approach the effect of the radiation pressure on dynamical trajectories, density profiles and escaping thermal flux. Our work is a generalization of the study by Bishop and Chamberlain (1989). In this second part of our work, we present here the density profiles of atomic Hydrogen in planetary exospheres subject to the radiation pressure. We first provide the altitude profiles of ballistic particles (the dominant exospheric population in most cases), which exhibit strong asymmetries that explain the known geotail phenomenon at Earth. The radiation pressure strongly enhances the densities compared with the pure gravity case (i.e. the Chamberlain profiles), in particular at noon and midnight. We finally show the existence of an exopause that appears naturally as the external limit for bounded particles, above which all particles are escaping
