How to Collect your Water Sample and Interpret the Results for the Poultry Analytical Package

Rapidly growing birds may consume up to twice as much water as feed (Scantling and Watkins 2013), which means a plentiful supply of clean water is crucial for poultry health and productivity. To determine the quality of your poultry’s water resources, periodic sampling and analysis is needed. Analyzing water supplies can also be a crucial tool in identifying existing or potential challenges. The Arkansas Water Resources Center (AWRC) in cooperation with the UA Cooperative Extension Service offers several analytical packages to assess the quality of your water resources. This document is intended to provide guidance to poultry producers on collecting water samples for analysis and understanding the “Poultry Water Report Form” provided by the AWRC’s Water Quality Laboratory (Lab). The information contained within this fact sheet should be used as general guidance, and the reader is encouraged to seek advice from Extension specialists regarding the interpretation of individual reports and water testing results that may be of concern

From the Forest to the River: Citizens\u27 Views of Stakeholder Engagement

Since the early 1990s collaboration and consensus processes have become associated with success in the environmental policy and natural resource policy arenas. Interest in collaboration and consensus processes have emerged, in part, out of a frustration with more conventional efforts used to involve stakeholders, to work though conflicts, and to make decisions in the environmental and natural resource policy arenas. Collaboration and consensus processes, when designed well and applied appropriately, provide opportunities for meaningful stakeholder engagement. This essay features aspects of two government-led or agency-based (Koontz et al. 2004; Moore and Koontz 2003) planning efforts that consider collaboration and citizens/stakeholder engagement. Both projects, a forest management plan revision on the Allegheny National Forest in Pennsylvania, and a regional sediment management planning effort at the mouth of the Columbia River in the Pacific Northwest, have considered a Collaborative Learning (CL) approach (Daniels and Walker 2001) for stakeholder involvement. As part of these CL applications, citizens/stakeholders have been asked for their views of the kind of participation processes they value and how they prefer to be involved. This essay presents a summary of citizens\u27 ideas. In doing so, it addresses the question: How do stakeholders want to be engaged in agency-led planning efforts? Data reveal that stakeholders prefer active engagement, access to information and events, and clearly defined decision space. Prior to presenting the project data germane to this question, the paper highlights the trinity of voice and Collaborative Learning

Using a Diverse Seed Mix to Establish Native Plants on a Sonoran Desert Burn

Revegetating burned areas is a formidable challenge facing resource managers in southwestern United States arid lands. Natural revegetation of desert burns by native species may be slow, or dominated by exotic annual grasses that perpetuate a frequent-fire regime. Resource managers may have several reasons for actively revegetating burns with native species, such as for providing competition with exotic species, minimizing soil erosion and dust pollution, and improving aesthetics. The use of native species in revegetation has been limited by a lack of available seed and by findings that native desert species are difficult to establish (e.g., Bainbridge and Virginia 1990, Banjerjee et al. 2006). Seeding may be one of only a few feasible options for reintroducing propagules to large desert burns covering thousands of hectares. Our objective was to assess the outcome of a 28-species (all native) operational seeding project for revegetating a 2005 burn in the Arizona Upland Subdivision of the Sonoran Desert

Homogeneous Subgroups of Young Children with Autism Improve Phenotypic Characterization in the Study to Explore Early Development

The objective of this study was to identify homogenous classes of young children with autism spectrum disorder (ASD) to improve phenotypic characterization. Children were enrolled in the Study to Explore Early Development between 2 and 5 years of age. 707 children were classified with ASD after a comprehensive evaluation with strict diagnostic algorithms. Four classes of children with ASD were identified from latent class analysis: mild language delay with cognitive rigidity, mild language and motor delay with dysregulation, general developmental delay, and significant developmental delay with repetitive motor behaviors. We conclude that a four-class phenotypic model of children with ASD best describes our data and improves phenotypic characterization of young children with ASD. Implications for screening, diagnosis, and research are discussed

Neighborhood ethnic density and preterm birth across seven ethnic groups in New York City

Residential segregation limits non-white ethnic groups' access to white neighborhood resources, but may also reduce their exposure to discrimination and facilitate social support. We computed adjusted preterm birth risk differences (RDs) for seven ethnic groups comparing > 25% to ≤ 25% ethnic density neighborhoods using 1995–2003 New York City birth records and a spatial ethnic density measure. RDs ranged from −15.0 per 1000 (95% CI: −18.5, −11.4) for whites to 6.4 per 1000 (95% CI: 2.8, 9.9) for blacks, with Hispanic and Asian estimates falling in between but tending to be protective. Results suggest that ethnic density is uniquely harmful for non-Hispanic blacks

Black Preterm Birth Risk in Nonblack Neighborhoods: Effects of Hispanic, Asian, and Non-Hispanic White Ethnic Densities

Studies of ethnic density and health in the United States have documented poorer health outcomes in black compared to non-black neighborhoods, but few studies have considered the identities of the non-black populations

Mutation of CFAP57, a protein required for the asymmetric targeting of a subset of inner dynein arms in Chlamydomonas, causes primary ciliary dyskinesia

Primary ciliary dyskinesia (PCD) is characterized by chronic airway disease, reduced fertility, and randomization of the left/right body axis. It is caused by defects of motile cilia and sperm flagella. We screened a cohort of affected individuals that lack an obvious axonemal defect for pathogenic variants using whole exome capture, next generation sequencing, and bioinformatic analysis assuming an autosomal recessive trait. We identified one subject with an apparently homozygous nonsense variant [(c.1762C\u3eT), p.(Arg588*)] in the uncharacterized CFAP57 gene. Interestingly, the variant results in the skipping of exon 11 (58 amino acids), which may be due to disruption of an exonic splicing enhancer. In normal human nasal epithelial cells, CFAP57 localizes throughout the ciliary axoneme. Nasal cells from the PCD patient express a shorter, mutant version of CFAP57 and the protein is not incorporated into the axoneme. The missing 58 amino acids include portions of WD repeats that may be important for loading onto the intraflagellar transport (IFT) complexes for transport or docking onto the axoneme. A reduced beat frequency and an alteration in ciliary waveform was observed. Knockdown of CFAP57 in human tracheobronchial epithelial cells (hTECs) recapitulates these findings. Phylogenetic analysis showed that CFAP57 is highly conserved in organisms that assemble motile cilia. CFAP57 is allelic with the BOP2/IDA8/FAP57 gene identified previously in Chlamydomonas reinhardtii. Two independent, insertional fap57 Chlamydomonas mutant strains show reduced swimming velocity and altered waveforms. Tandem mass tag (TMT) mass spectroscopy shows that FAP57 is missing, and the g inner dyneins (DHC7 and DHC3) and the d inner dynein (DHC2) are reduced, but the FAP57 paralog FBB7 is increased. Together, our data identify a homozygous variant in CFAP57 that causes PCD that is likely due to a defect in the inner dynein arm assembly process

Genetic Determinism and the Innate-Acquired Distinction in Medicine

This article illustrates in which sense genetic determinism is still part of the contemporary interactionist consensus in medicine. Three dimensions of this consensus are discussed: kinds of causes, a continuum of traits ranging from monogenetic diseases to car accidents, and different kinds of determination due to different norms of reaction. On this basis, this article explicates in which sense the interactionist consensus presupposes the innate–acquired distinction. After a descriptive Part 1, Part 2 reviews why the innate–acquired distinction is under attack in contemporary philosophy of biology. Three arguments are then presented to provide a limited and pragmatic defense of the distinction: an epistemic, a conceptual, and a historical argument. If interpreted in a certain manner, and if the pragmatic goals of prevention and treatment (ideally specifying what medicine and health care is all about) are taken into account, then the innate–acquired distinction can be a useful epistemic tool. It can help, first, to understand that genetic determination does not mean fatalism, and, second, to maintain a system of checks and balances in the continuing nature–nurture debates
