Forensic Fisheries Science: Literature Review and Research Suggestions

Recent years have seen a dramatic increase in litigation against the National Marine Fisheries Service, NOAA. Litigation may affect personnel throughout the agency, including scientists, whose work is often directly or indirectly influenced by complex legal requirements, but who may not be in a position to comment or engage in public dialogue. It may be helpful for scientists and other agency personnel to join the ongoing discussion in the legal community regarding the interface of science and law. This paper provides a starting point with a selected introduction to relevant legal literature in this area. It uses the phrase “forensic fisheries science” to describe the application of science to legal requirements in the fishery management context. It concludes with suggestions for future research that could assist NMFS scientists as they grapple with the challenge of using science to help the agency meet its complex legal requirements. Forensic: belonging to, used in, or suitable to courts of judicature or to public discussion and debate; argumentative, rhetorical; relating to or dealing with the application of scientific knowledge to legal problems (Merriam-Webster Online Dictionary

Shaping the criminal justice system: the role of those supported by Criminal Justice Service

In Scotland, the development and delivery ofpersonalised social work services has been part of a wider public service reform agenda, building on Changing lives: report of the 21st century review of social work (Scottish Executive, 2006). This agenda has focused on harnessing the strengths, predilections, networks and capacities of those supported by services, to inform the design and delivery of services. To date, the place of criminal justice in this reform agenda has received comparatively limited attention (Weaver, 2011). This Insight focuses on the issue of involving those who have offended in shaping the criminal justice system, exploring the different models of involvement, the effectiveness of different approaches and the implications for Criminal Justice Social Work services

Regulation of reactivated elongation in lysed cell models of teleost retinal cones by cAMP and calcium.

Teleost retinal cones elongate in the dark and contract in the light. In isolated retinas of the green sunfish Lepomis cyanellus, cone myoids undergo microtubule-dependent elongation from 5 to 45 micron. We have previously shown that cone contraction can be reactivated in motile models of cones lysed with Brij-58. Reactivated contraction is both actin and ATP dependent, activated by calcium, and inhibited by cAMP. We report here that we have obtained reactivated cone elongation in lysed models prepared by the same procedures. Reactivated elongation is ATP dependent, activated by cAMP, and inhibited by calcium. The rate of reactivated elongation is proportional to the cAMP concentration between 10 microM and 0.5 mM, but is constant between 10 microM and 1.0 mM Mg-ATP. No elongation occurs if cAMP or Mg-ATP concentration is less than or equal to 5 microM. Mg-ATP is required for both cAMP-dependent and cAMP-independent processes, suggesting that Mg-ATP is required both for a regulatory process entailing cAMP-dependent phosphorylation and for a force-producing process. Free calcium concentrations greater than or equal to 10(-7) reduce the elongation rate by 78% or more, completely inhibiting elongation at 10(-5) M. This inhibition is not due to competition from calcium-activated contraction. Cytochalasin D blocks reactivated contraction, but does not abolish calcium inhibition of reactivated elongation. Thus calcium directly affects the elongation mechanism. Calcium inhibition is calmodulin dependent. The calmodulin inhibitor trifluoperazine abolishes calcium inhibition of elongation. Furthermore, calcium blocks elongation only if present during the lysis step; subsequent calcium addition has no effect. However, if calcium plus exogenous calmodulin are subsequently added, elongation is again inhibited. Thus calcium inhibition appears to require a soluble calmodulin which is lost shortly after lysis

An Educational Pathway for Geriatric Home Caregivers

The establishment of a multi-tiered educational pathway for geriatric home caregivers would support efforts to meet the needs of an increasing number of community dwelling older adults who require assistance with activities of daily living, while generating a cadre of qualified employees for an expanding non-medical private home care market. An educational pathway for geriatric home caregivers would also standardize the training of home care assistants while providing these individuals access to routine, high quality continuing education opportunities and the potential for career advancement. This issue brief provides two model educational pathways toward becoming a Geriatric Home Caregiver

Leveraging University-School District Research Partnerships: Exploring the Longitudinal Effects of an Early Kindergarten Transition Program

With increasingly tight budgets, many public school districts lack research personnel to evaluate program efficacy or investigate best practices that raise student achievement. We highlight an example of a successful university-district partnership that offers district-driven research support while providing opportunities for practitioner-scholars to learn first-hand how to perform rigorous evaluation work. This article details the Early Kindergarten Transition program evaluation study conducted by a university-district partnership as well as testimony from district leadership on the utility of the research deliverables and long-term benefits of the research collaboration

Building an On-Ramp to Children's Health Coverage: A Report on California's Express Lane Eligibility Program

Documents the successes and current policy and procedural barriers to enrolling eligible but uninsured children through California's Express Lane Eligibility initiative, which has been piloted in 72 schools in five school districts across California

"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

Impact of Teat Order on Feed Consumption in Swine from Birth to Nursery

A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Overall, no effect of teat order was found on average daily gain, average daily feed intake, gain-to-feed ratio, or body weight among pigs from each section of the udder. Differences did occur during certain stages of nursery, which can be of economic importance to producers. No difference was seen in active or total ghrelin levels or the active-to-total ghrelin ratio in relation to teat order, although there were differences in active and total ghrelin concentrations among the sampling days. Further research should be carried out to investigate what factors would contribute to this data contradicting previous inferences about the relationship of teat order and feed consumption in pigs
