Critics of economic impact studies that purport to show that mega-events such as the Olympics bring large benefits to the communities "lucky" enough to host them frequently cite the use of inappropriate multipliers as a primary reason why these impact studies overstate the true economic gains to the hosts of ...

Sports betting and sports have always been strongly connected. Traditionally, these betting markets have been cleared by bookmakers, who accept bets on certain events. These bookmakers carry the risk of paying the amount wagered if the event occurs. Recently, a new type of betting market has appeared, so-called betting exchanges. ...

Home advantage in football varies over time. Existing theories of home advantage struggle to explain this time-series variation. We argue that the decline in home advantage in English football since the mid-1980s was partly caused by the advent of televised football. We argue that the increase in live television coverage ...

China spent far more on the 2008 Olympiad than any previous host country. A retrospective assessment of the benefits of the 2008 Games to the Chinese economy will not be possible for several years. We use an adaptation of event study methodology that has been employed by studies of previous ...

Nitrogen management in Western Australia (WA) and in cropping areas elsewhere in Australia assumes that soil contains negligible or no positive charge and is therefore unable to retain nitrate against leaching. The amount of water needed to displace nitrate is thus assumed to be the drainable volume of water held ...

Crop yield potential is a chief determinant of nutrient requirements, but there is little objective information available on the gains in profitability that can be made by accounting for the influences of soil type and season on yield potential when making fertiliser decisions. We conducted such an assessment using crop ...

Low soil moisture and phosphorus (P) deficiencies restrict grain production in south-eastern Australia. The effect of the soil moisture regime on the plant availability of P from fluid mono-ammonium phosphate (MAP) fertiliser was examined during vegetative growth of wheat and canola in P-responsive soils from the Wimmera, Mallee, and high ...

Root growth responses to separately placed of bands of N and P fertiliser were examined at the 3-leaf(GS13) and stem extension growth stages (GS30) for wheat (Triticum aestivum L. cv. Yitpi) growing in 2 major alkaline soil types from the rainfed (375-420 mm) grain production regions of south-eastern Australia. Intact ...

Crop yield and profitability in the dryland production systems of southern Australia are directly affected by the application of nitrogen (N) and phosphorus (P) fertilisers. How efficiently a crop utilises applied fertiliser is affected by several factors that interact in a complex way, including: nutrient mobility, soil type and soil ...

Abstract. Negative potassium (K) balances in all broadacre grain cropping systems in northern Australia are resulting in a decline in the plant-available reserves of K and necessitating a closer examination of strategies to detect and respond to developing K deficiency in clay soils. Grain growers on the Red Ferrosol soils ...

Phosphorus (P) and nitrogen (N) exports from cropping areas can be greater than those from uncropped areas. Conservation farming methods, involving minimal tillage and full stubble retention, offer significant benefits to grain cropping, but may increase nutrient concentrations in surface (i.e. 0-20 mm) soils, resulting in increased risks of nutrient ...

Major changes in tillage practices have occurred over the past 2 decades across the diverse range of soil types and rainfall zones that characterise cropping systems in southern Australia. However, there has been little corresponding change in the management of nutrients, especially phosphorus (P). This study investigated the effects of ...

Much of our knowledge of plant growth in response to soil nutrient supply comes from studies under homogeneous soil conditions. However, the adoption of reduced or nil tillage and shallow banding of fertilisers at the time of seeding causes spatially variable distribution and availability of soil nutrients in agricultural lands. ...

In the present paper, we review 4 topics that were identified through extensive consultation with stakeholders as issues of high impact and influence for the grains industry: improving soil testing and interpretation; role of fluid fertilisers in the Western Australian (WA) grains industry; using spatial and temporal information to improve ...

Marie Charlotte Carmichael Jones was a truly remarkable woman. In the face of enormous opposition and difficulties, she pioneered safe and effective birth control for women. She wrote the first popular book on this subject, which first appeared 90 years ago and which became an instant best seller. Marie was ...

Articular cartilage in adults has a poor ability to self-repair after injury. A variety of cartilage resurfacing techniques have the potential to improve the repair of cartilage defects and reduce the patient's disability. The most advanced of these techniques is autologous chondrocyte implantation. It promises to provide normal organogenesis leading ...
