The adoption of market-based instruments for resource management: Three case studies

Market-based instruments (MBIs) for resource management create financial incentives for people and businesses to use resources more efficiently, within a regulatory context designed to ensure that ecological, social and cultural objectives are also met. Three case studies were done to identify factors influencing the adoption or rejection of market-based instruments in New Zealand. Case studies included Individual Transferable Quota (ITQ) for New Zealand's inshore fisheries, Transferable Water Permits (TWPs) in Tasman District and Waikato Region, and charges for occupation of coastal space at both the national and regional levels in New Zealand. This paper provides a summary of findings from these case studies. These include: MBIs are difficult to implement if they threaten the position of existing users. It is important to have clear objectives. Norms and values can be an obstacle to MBIs, especially where they help to protect the interests of key stakeholders, but value-based opposition can be overcome if practical concerns are addressed.market-based instruments, ITQ, transferable water permits, coastal occupation charges, Agribusiness, Agricultural and Food Policy, Consumer/Household Economics, Crop Production/Industries, Environmental Economics and Policy, Farm Management,

Coupled Fluids-Radiation Analysis of a High-Mass Mars Vehicle

The NEQAIR line-by-line radiation code has been incorporated into the DPLR Navier-Stokes flow solver such that the NEQAIR subroutines are now callable functions of DPLR. The coupled DPLR-NEQAIR code was applied to compute the convective and radiative heating rates over high-mass Mars entry vehicles. Two vehicle geometries were considered - a 15 m diameter 70-degree sphere cone configuration and a slender, mid-L/D vehicle with a diameter of 5 m called an Ellipsled. The entry masses ranged from 100 to 165 metric tons. Solutions were generated for entry velocities ranging from 6.5 to 9.1 km/s. The coupled fluids-radiation solutions were performed at the peak heating location along trajectories generated by the Traj trajectory analysis code. The impact of fluids-radiation coupling is a function of the level of radiative heating and the freestream density and velocity. For the high-mass Mars vehicles examined in this study, coupling effects were greatest for entry velocities above 8.5 km/s where the surface radiative heating was reduced by up 17%. Generally speaking, the Ellipsled geometry experiences a lower peak radiative heating rate but a higher peak turbulent convective heating rate than the MSL-based vehicle

Influence of Topping and Harvest Management on the Evaluation of Data From Burley Tobacco Variety Trials

Tobacco producers are always interested in new tobacco varieties, and are continually searching for the best variety. Producers receive information about varieties from a number of sources including; research and extension publications, county extension agents, neighbors, farm supply workers, and seed producers. To help producers evaluate varieties, county agents in cooperation with tobacco specialists conduct many burley tobacco variety trials at the county level

A proteomic approach to identify endosomal cargoes controlling cancer invasiveness

We have previously shown that Rab17 - a small GTPase associated with epithelial polarity - is specifically suppressed by ERK2 signalling to promote an invasive phenotype. However, the mechanisms through which Rab17 loss permits invasiveness, and the endosomal cargoes that are responsible for mediating this are not known. Using quantitative mass spectrometry-based proteomics, we have found that knockdown of Rab17 leads to highly selective reduction in the cellular levels of a v-SNARE (Vamp8). Moreover, proteomics and immunofluorescence indicate that Vamp-8 is associated with Rab17 at late endosomes. Reduced levels of Vamp8 promote transition between ductal carcinoma in situ (DCIS) and a more invasive phenotype. We developed an unbiased proteomic approach to elucidate the complement of receptors that redistributes between endosomes and the plasma membrane, and have pin-pointed neuropilin-2 (NRP2) as a key pro-invasive cargo of Rab17/Vamp8-regulated trafficking. Indeed, reduced Rab17 or Vamp8 levels lead to increased mobilisation of NRP2-containing late endosomes and upregulated cell surface expression of NRP2. Finally, we show that NRP2 is required for the basement membrane disruption which accompanies transition between DCIS and a more invasive phenotype

Functional analysis of a human A1 adenosine receptor/green fluorescent protein/Gi1α fusion protein following stable expression in CHO cells

AbstractFusion proteins between the human A1 adenosine receptor and the pertussis toxin resistant (Cys351Gly) mutant of the G-protein α subunit Gi1α (A1/Gi), and between the human A1 adenosine receptor, the Aequorea victoria green fluorescent protein (GFP) and Cys351Gly Gi1α (A1/GFP/Gi), were expressed in CHO cells. The agonist NECA caused a stimulation of [35S]GTPγS binding at both fusion proteins with similar concentration dependence as at the native receptor. However in the presence of pertussis toxin NECA stimulation of [35S]GTPγS binding was only seen at the A1/GFP/Gi fusion protein. The regulation of the adenylyl cyclase and MAP kinase effector systems by both fusion proteins was attenuated following pertussis toxin treatment. These studies demonstrate for the first time the characterisation of a fusion protein between a G-protein coupled receptor, GFP and a G-protein α subunit

Front End Planning of Railway Projects

ABSTRACT Infrastructure capital projects are at the center of efforts to invest in the recovery of the economy, both domestically and internationally, and are seen as a primary growth engine of the construction industry today. Sadly, many of these projects are unsuccessful due to poor early project planning. Front End Planning (FEP) is a critical process for uncovering project unknowns, while developing adequate scope definition and a structured approach for the project execution process. FEP assists in identifying and mitigating issues such as right-of-way concerns, utility adjustments, environmental hazards, logistic problems, permitting requirements and so on. This paper will outline research funded by the Construction Industry Institute (CII) focused on front end planning of infrastructure projects. This investigation, which includes input from domestic and foreign planning experts from over 30 organizations using as reference over 60 capital projects, provides an understanding of the critical issues that must be addressed during FEP of infrastructure projects, particularly as applied to rail projects. A new risk management tool for FEP, called the Project Definition Rating Index (PDRI) for Infrastructure Projects, will be shown. Critical success factors for FEP of railway and infrastructure projects will be shared, including key planning process steps, along with guidance to practitioners involved in planning these types of projects
