The value of native birds in New Zealand: Results of a Waikato Survey

Several New Zealand studies have placed a value on recreation. Very few have placed a value on native birdlife. In December 2007 and January 2008, we conducted a phone survey in the Waikato Region of New Zealand. 207 people answered 13 questions on native birds. 97% of respondents enjoy having birds in their area both listening and watching. The Tui is the most important bird respondents either see currently or would like to see. If there were a greater variety of bird types in their area, respondent well-being would increase significantly. Most respondents would be willing to pay an extra amount in their annual rates to support native bird projects within the Waikato Region

The value of native bird conservation: A New Zealand case study

During December 2007 and January 2008, telephone surveys were used to randomly sample Waikato, New Zealand residents. The purpose of the surveys was to determine whether respondents valued native bird conservation programmes in their area. We elicited the contingent valuation approach to determine the value in terms of their willingness-to-pay (WTP) to support regional conservation initiatives aimed at protecting, or restoring, native bird populations. Results indicated that local birdlife was regarded positively by residents and that they were in favour of local conservation and restoration initiatives. 86% of respondents were willing-to-pay an annual addition to their rates (taxes) to support these initiatives. Conservatively, the value of native bird conservation in the region was approximately $13 million (2008 NZ$). Willingness to support these initiatives depended strongly on income, ethnicity and age. The positive WTP for additional regional rates for local birdlife conservation suggests that there could potentially be an underinvestment in birdlife conservation in the Waikato region, and that regional bodies could draw upon local funding, as opposed to relying on central government funding, to support these initiatives

Innate and discretionary accruals quality and corporate governance

This paper extends previous research on the association between corporate governance mechanisms and accruals quality. We derive measures of the discretionary and innate components of accruals quality and regress them against corporate governance characteristics. For discretionary accruals, we find use of a Big 4 audit firm and a larger audit committee as the primary governance mechanisms associated with higher accruals quality. For innate accruals quality, we find that higher quality is associated with an independent board of directors, a larger, more independent and more active audit committee, and use of a Big 4 audit firm. Our findings suggest a stronger relation between sound governance mechanisms and innate accruals quality than discretionary accruals quality.Full Tex

A link between transcription fidelity and pausing in vivo

Pausing by RNA polymerase is a major mechanism that regulates transcription elongation but can cause conflicts with fellow RNA polymerases and other cellular machineries. Here, we summarize our recent finding that misincorporation could be a major source of transcription pausing in vivo, and discuss the role of misincorporation-induced pausing

Women on boards and greenhouse gas emission disclosures

We apply institutional and board capital theory to examine whether women on boards are associated with disclosure and quality of <i>corporate greenhouse gas</i> (GHG) emissions related reporting. We examine the research problem in Australia in a period when no requirements existed for listed companies to appoint female directors or to report GHG emissions. This environment allows us to examine the association between women on boards and GHG emissions related disclosure in annual and sustainability reports in a voluntary setting. We find that companies with multiple female directors make GHG emissions related disclosures that are of higher quality

Misincorporation by RNA polymerase is a major source of transcription pausingin vivo

The transcription error rate estimated from mistakes in end product RNAs is 10−3–10−5. We analyzed the fidelity of nascent RNAs from all actively transcribing elongation complexes (ECs) in Escherichia coli and Saccharomyces cerevisiae and found that 1–3% of all ECs in wild-type cells, and 5–7% of all ECs in cells lacking proofreading factors are, in fact, misincorporated complexes. With the exception of a number of sequence-dependent hotspots, most misincorporations are distributed relatively randomly. Misincorporation at hotspots does not appear to be stimulated by pausing. Since misincorporation leads to a strong pause of transcription due to backtracking, our findings indicate that misincorporation could be a major source of transcriptional pausing and lead to conflicts with other RNA polymerases and replication in bacteria and eukaryotes. This observation implies that physical resolution of misincorporated complexes may be the main function of the proofreading factors Gre and TFIIS. Although misincorporation mechanisms between bacteria and eukaryotes appear to be conserved, the results suggest the existence of a bacteria-specific mechanism(s) for reducing misincorporation in protein-coding regions. The links between transcription fidelity, human disease, and phenotypic variability in genetically-identical cells can be explained by the accumulation of misincorporated complexes, rather than mistakes in mature RNA

Field Guide to Nonindigenous Marine Fishes of Florida

The purpose of this field guide is to provide information on nonindigenous (i.e., non-native) fishes that have been observed in Florida’s marine waters. Introductions of non-native marine fishes into Florida’s waters could be intentional or unintentional, and are likely from a variety of sources, including aquarium releases, escape from aquaculture, loss due to extreme weather events (e.g., flooding from hurricanes), and possibly transfer with ballast water or hull-fouling. Presently the lionfishes (Pterois volitans and P. miles) are the only non-native marine fish species known to be established along the coast of Florida. All other marine fishes in this guide (except the euryhaline species, see below) have infrequent occurrences, occur singly or in small groups, and have not yet become self-sustaining populations. Aquarium releases are one of the major pathways whereby nonindigenous fishes gain access to new environments (Ruiz et al. 1997; Fuller et al. 1999). Most of the nonindigenous marine fishes found in Florida’s waters are thought to be aquarium fishes that either were illegally released into the ocean or escaped captivity (e.g., during severe storm/flooding events). Indeed, south Florida is a hotspot for nonindigenous marine aquarium fishes (Semmens et al. 2004). Increased public awareness of the problems caused by released or escaped aquarium fishes may aid in stemming the frequency of releases. For example, HabitattitudeTM (www.habitattitude.net) is a national public awareness and partnership campaign that encourages aquarists and water gardeners to prevent the release of unwanted aquarium plants, fish and other animals. It prompts hobbyists to adopt alternative actions when dealing with these aquatic plants and animals. (PDF file contains 133 pages.

Electric power scheduling: A distributed problem-solving approach

Space Station Freedom's power system, along with the spacecraft's other subsystems, needs to carefully conserve its resources and yet strive to maximize overall Station productivity. Due to Freedom's distributed design, each subsystem must work cooperatively within the Station community. There is a need for a scheduling tool which will preserve this distributed structure, allow each subsystem the latitude to satisfy its own constraints, and preserve individual value systems while maintaining Station-wide integrity. The value-driven free-market economic model is such a tool
