An Economic Evaluation of a Pest Management Control Program: "Outfox the Fox"
No full textFoxes are regarded as a serious pest of environmental and grazing systems in Australia. The fox is a recognised predator of native wildlife and has been a significant contributor to the population decline of many native mammal, bird and reptile species. There are also claims that foxes may account for up to 30% of lamb mortalities in some areas, while mortality due to predation of 2 to 5% is more likely in most regions. The ‘Outfox the Fox’ program was established by NSW Agriculture in conjunction with a number of Rural Land Protection Boards to achieve a more strategic and coordinated fox baiting program. This program relies on a community driven and integrated management approach to the problem. The main features are to synchronise baiting across landholders at least twice a year, undertake baiting during periods when the fox is most susceptible, regularly check and replace baits, and continue until the bait take declines. A stochastic economic surplus and benefit-cost analysis model was developed to evaluate this program. The change in annual economic surplus due to the ‘Outfox the Fox’ program was 9.8m and a mean benefit-cost ratio of 13.0:1. The stochastic analysis indicated that there was a very low probability of this program providing a negative economic return.benefit cost analysis, research evaluation, economic surplus, fox, Farm Management, Land Economics/Use, Livestock Production/Industries, Production Economics, Research and Development/Tech Change/Emerging Technologies, Q160,
Can the increase of Fox density explain the decrease in Lynx numbers at Doňana ?
No full textSome preliminary data are presented on the abundance, food habits and habitat use of Lynx and Fox in Doňana. The methods used were : scent-stations lines and faecal sample censues (Fox), radio tracking (Lynx) and faecal counts and analysis of droppings (both species). Foxes outnumber Lynx at Doñana, but the latter use the edge of the marshes (the most productive habitat in the area), more than foxes do. Food data reveal little dietary overlap : Lynx are food specialists (preying mainly on rabbits), whereas foxes are generalists. Common use of rabbits as prey during the Fox breeding season could indicate exploitative competition. Further data are however needed for a better understanding of this interaction. The increase in Fox numbers probably followed the decline of the Lynx population.Nous présentons des résultats préliminaires sur l’abondance, l’alimentation et l’utilisation de l’habitat par le Renard et le Lynx à Doňana. Les méthodes employées sont : comptage des stations de marquage olfactif et recensements des excréments pour les renards, radio-pistage pour les lynx et analyse des excréments pour les deux espèces. Les renards sont actuellement plus abondants que les lynx, mais ces derniers utilisent plus souvent le bord des marais, c’est-à-dire les plus riches biotopes. L’analyse de la nourriture montre que le chevauchement des régimes est faible : le Lynx est un spécialiste des lapins, tandis que le Renard est un généraliste. La prédation commune des lapins pendant l’élevage des jeunes peut laisser supposer une compétition interspécifique. On a besoin de plus de données pour comprendre les interactions entre Lynx et Renard, mais on peut imaginer que si ce dernier est abondant c’est surtout parce que le premier est devenu rare.Rau J.R., Beltran Juan F., Delibes Miguel.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Financial Summit: J.R. Briggs & Dave Briggs
No full textDave and J.R. Briggs speak on stewardship of finances.
Dave Briggs currently serves as the stewardship director at Central Christian Church of Arizona. Previously he served in a similar role at Willowcreek Church and prior to that was a finance manager for GE for 27 years. He has developed numerous financial seminars and classes and regularly speaks at churches and conferences around the country. Dave and his wife Debbie had two sons attend Taylor and served for three years on the Taylor Parents’ Cabinet.
J.R. Briggs wears a variety of ministry hats. On a local level, he serves as one of the pastors of The Renew Community. He is also the Founder and Director of Kairos Partnerships and Director of Leadership and Congregation Formation for the Ecclesia Network. He is a life coach, consultant, frequent speaker, and author of seven books. He and his wife Megan, along with their two sons Carter and Bennett, live in the Philadelphia area
Posterior cingulate neurometabolite profiles and clinical phenotype in frontotemporal dementia
No full textProton magnetic resonance spectroscopy was used to compare metabolite levels from a posterior cingulate voxel in a group of patients with 2 syndromic subtypes of frontotemporal dementia (n = 10) and an age and education-matched group with Alzheimer disease (n = 10). Overall, frontotemporal dementia was indistinguishable from Alzheimer disease, though differences in N-acetylaspartate emerged between patients with the SD and progressive nonfluent aphasia subtypes, attributable to 2 atypical results among the latter. Such values may index cases with atrophy in posterior cortical regions presenting with progressive nonfluent aphasi
The effect of turbulence on particle impaction om a cylinder in a cross flow
No full textParticle impaction on a cylinder in a cross flow is investigated with the use of Direct Numerical Simulations (DNS), with a focus on the effect of turbulence on the impaction efficiency. It is found that for particles with Stokes numbers in the boundary stopping mode there is up to ten times more front side impaction for turbulence with a large integral scale, than for a corresponding laminar flow. The back side impaction efficiency is also found to be influenced by the turbulence. The highest back side impaction efficiency is found for turbulence with small integral scales
