No full textAssessing resilience in Collie: a case study in Western Australia
No full textResilience is a system’s ability to absorb or adapt to change without losing essential structures and functions. In a changing world, resilience assessment is a means of assessing the condition of complex ecological and social systems in the face of multiple trends and threats. This thesis examines the usefulness of resilience assessment as a policy tool when applied to communities that will be affected by policies to reduce greenhouse gas emissions, via a case study of Collie, Western Australia. A historical analysis shows that Collie’s coal industry is in the late conservation stage of an adaptive cycle and vulnerable to collapse. Current threats to the industry include climate change, greenhouse gas mitigation policies, competition from other energies, local air quality concerns, growing industrial demand for water and finite coal reserves. While some threats are volatile and therefore predictions are uncertain, these threats appear likely to push the industry into serious decline within the near to medium term (10–15 years). Collie has some capacity to adapt to such a transition, including moderate existing economic diversity and strong social capital but it appears that community awareness about the threats could be enhanced. In addition, there is evidence that perverse resilience influences energy policy in Western Australia, with persistent structures and functions that cause social and environmental harm. These are causing unequal flow of wealth and opportunity in Collie and are undermining its adaptive capacity. If new coal projects proceed, Collie will sacrifice important assets including water supplies, rivers, clean air, rural lifestyle, sense of place and heritage, along with future opportunities to diversify its economy. Alternatively, it could prepare now for inevitable transition. Resilience assessment is a useful tool for other communities that are likely to experience transition owing to climate change and resource depletion, including north-west WA towns that are also home to high greenhouse gas-intensity industries
WPA Interview - W. S. Collie and Mrs. R. L. James
No full textA transcript of a WPA interview by Chas R. Fuller with W. S. Collie and Mrs. R. L. James regarding a building at the intersection of Houston and Weatherford St in the 1930s. The building was originally owned by Mrs. James\u27 husband. It has been the offices of a number of business before being torn down in 1930 to make sure for a building that housed the Renfro Drug Store.https://mavmatrix.uta.edu/specialcollections_workprojectsadministration/1139/thumbnail.jp

Reproduktionsproblem hos border collie
No full textMålet för denna studie var att undersöka om det finns en underliggande reproduktionsproblematik hos rasen border collie idag som ej är känd. För första gången har tikars förlopp samt uppfödares beslut rapporterats in gällande parning, dräktighet samt valpning. Data har samlats in från 184 par-ningar och 173 kullar vilket har jämförts med andra raser samt officiella siffror från Svenska Kennel-klubben (SKK) gällande registrerade kullar och valpar hos border collie.
Valpningsfrekvensen för parade tikar var hög och dräktighetsförluster förekom hos 1,7 % av tikar som konstaterats dräktiga. Endast 4,9 % av tikar som parades blev ej dräktiga där ett samband kunde ses för antal parningar samt om uppfödare använt sig av progesteronprov eller ej. Majoriteten av kullarna föddes under vinterhalvåret där den totala valpdödligheten var signifikant högre än under sommarhalvåret. Den generella valpdödligheten för border collievalpar de första levnadsveckorna uppgick till 10,4 %, varav 5,3 % av valparna var dödfödda, där en signifikant skillnad även kunde ses hos tikar som vaccinerats för herpes. Herpesvaccinering tillämpades i 40 % av fallen vilket är en växande trend trots att herpesviruset ej kunnat kopplas till uteblivna dräktigheter, små kullar eller ökad valpdödlighet i denna studie. Tikarna valpade utan hjälp i 71 % av fallen men tikar som valpat med komplikationer tidigare i sitt liv löpte signifikant större risk för komplikationer även vid nästa valpning. Den genomsnittliga kullstorleken för border collien var 6,5 valpar per kull.
Uppfödare använde sig av veterinärmedicinska hjälpmedel i 30 % av fallen för att hitta optimal parningstidpunkt. 72 % av uppfödarna använde sig av bilddiagnostik för att konstatera dräktighet eller räkna foster vilket är en viktig pusselbit för att påvisa fosterresorption samt abortering. Sammantaget visar studiens resultat att border colliens reproduktionsläge kan anses vara gott.The aim of this study was to investigate if there are any underlying reproductive difficulties within the border collie breed. For the first time the status of the bitches, and breeders’ decisions were recorded during mating, pregnancy and whelping. Data were collected for 184 matings and 173 litters, which were compared with data from other breeds and official numbers from the Swedish Kennel club (SKK) regarding registered litters and pups of the border collie breed.
The whelping rate for mated bitches was high: pregnancy losses occurred in 1.7% of bitches that were found to be pregnant. Only 4.9% of the mated bitches were not pregnant: an association could be seen between the number of matings made and whether or not the breeder tested the bitch´s serum progesterone level before mating. The majority of the litters were born during winter: puppy mortality was also higher in winter than during the summer. The total puppy mortality was 10.4%, with 5.3% of the pups being stillborn. The bitches whelped unaided in 71% of the cases but results indicate that bitches with a history of complications at earlier whelpings showed a greater risk of complications for their next whelping as well. The average litter size for the border collie was 6.5 pups, which was not affected by season. Season, however, and whether or not the bitches were vaccinated against herpes, affected puppy mortality. Herpes vaccination was performed in 40% of the bitches, increasing from previous years, even though no connection was found in this study that herpes infection was linked to non-pregnant bitches, small litters or an increased puppy mortality.
Breeders used veterinary medical aids such as analyzing serum progesterone levels before mating in 30% of the cases, to find the best breeding window of the bitch. In addition, 72% of the breeders used imaging diagnostics to confirm pregnancy or to count the number of pups before whelping, which is also important for confirming and diagnose embryonal resorption and abortion. Overall, the reproductive state of the border collie can be considered as good

No full textThe dog has evolved from the wolf which is the most common species among the predators. The domestication and selection have resulted in different breeds of dogs, which include changed characteristics and personalities. With time, dogs have become more common to have as a pet for different purposes. For example, for hunting, guarding or herding, to name a few. In addition, all dogs have a variety of conducts and needs. Shepherd dogs, such as the Border Collie, require daily mental and physical activation to remain satisfied. Over the years, the main activity for this breed has been herding, but today the Border Collie is used as a working dog, as well as within other types of activities and training.
Herding is a genetic behaviour in shepherd dogs. Besides genetics, research has showed that socialization, enriching experiences and environment also play a significant role in their behaviours. The aim with this study is to investigate if the Border Collie can be satisfied, healthy and a happy dog without herding. The result of this study revealed that most Border Collie owners walk their dogs two hours a day, 72% activate their dogs regularly through herding and 56% through obedience. Owners consider their dogs satisfied no matter if they allowed their dogs to herd or not. Both the owners who allowed their dogs to herd and those who did not, experienced behaviour problems with their dogs, for example, an excessive herding of cars, children and bikers.
18% of the owners who let their dogs perform herding, experienced one or more behaviour problems. At the same time, only 8% of the owners who did not let their dogs perform herding, experienced one or more behaviour problems in their dog. One of the most common behaviour problem reported by the owners who practiced herding, was that their dog had a strong urge to herd and a aggressive behaviour. Remaining owners who did not practice herding with their dogs, instead perceived fear to be the main behaviour problem their dog to have
State aid to investment and R&D
No full textThe prohibition of state aid to investment and R&D in an integrated market such as the European Community is analysed in a Cournot oligopoly model where firms undertake investment or R&D to reduce their costs. Both strategic and non-strategic investment and R&D are considered. Governments in the Member States give subsidies for investment and R&D, which are financed by distortionary taxation so the opportunity cost of government revenue exceeds unity. Prohibiting state aid to investment will always increase aggregate welfare. Prohibiting state aid to R&D will always increase aggregate welfare if spillovers from R&D are small. If spillovers from R&D are moderate then there exists a range of values for opportunity cost where governments give state aid and where the prohibition of state aid will increase aggregate welfare. Prohibiting state aid to R&D will reduce aggregate welfare if spillovers from R&D are large.State aid prohibition, Cournot oligopoly model, R&D spillovers, distortionary taxation, Collie, R&D, research and development
