  • Within the overall transport process, attenuation processes may cause movement of the chemical to differ from that of the bulk flowing groundwater, for example dispersion, sorption and chemical or biological degradation of the chemical. Such attenuation processes potentially act to mitigate the impact of chemicals and are a function of both the specific chemical and geologic domain. Indeed, attenuation may vary significantly between individual chemicals and within different geological settings.

  • But, if recessions are different and shocks transmit both domestically and internationally in a time varying fashion, should not we employ a broader set of regressors -and potentially models -to better track this variability across time? For example, many recent approaches to forecasting consider pooling the individual forecasts stemming from a large number of models, each differing from the other as concerns for example the lag specification, the sample over which estimation is carried out, the number of variables included.

  • This report evaluates the responses of the United Nations to the questions of human cloning governance. The difference between reproductive human cloning and using of cloning technology for research is explained followed by an ethical analysis of cloning. Discussion of ethics at the UN level often brings to mind the notion of deep, profound, commonly held principles to guide human actions. While general ethical principles, such as the principle of doing no harm in medical practice, are widely respected, the question of what amounts to harm is less easily defi ned.

  • Insemination skills of 37 inseminators participating in AI programmes supported by the government, farmers’ cooperatives and Non-Governmental Organizations (NGOs) were evaluated during 11 December 2001 and 8 May 2002 in 4 batches. Individual inseminators were asked to thaw a straw of frozen semen. The thawing time adopted by the inseminators and the temperature of the water used were recorded. They were then asked to simulate an insemination by depositing gentian violet dye in the genital tracts removed from slaughtered cows.

  • Another critical barrier to access is discrimination by state laws or fertility clinics. Coverage in five of the states with insurance mandates 12 is only available to married couples, and four of these states 13 mandate use of the husband’s sperm, eliminating the possibility of donor sperm. Some fertility clinics only offer services to married couples as well. The American Society for Reproductive Medicine reports that fertility clinics vary in their willingness to treat single women, single men, lesbian couples, and gay male couples.

  • One focus of this monograph is on how human capital interacts with financial capital. Understanding this interaction helps us to create, manage, protect, bequest, and especially, appropriately consume our financial resources over our lifetimes. In particular, we propose ways to optimally manage our stock, bond, and so on, asset allocations with various types of insurance products. Along the way, we provide models that potentially enable individuals to customize their financial decision making to their own special circumstances....

  • Osteoporosis and fractures may increase due to hypoestrogenism in menopause and cytochrome P450 inducing AEDs. Recent studies suggest lower bone mineral density (BMD) in adults and children with epilepsy, irrespective of AED treatment. Both idiopathic epilepsy and symptomatic epilepsy are associated with reduced BMD, with the greatest reduction in symptomatic generalized epilepsy (Sheth & Hermann, 2008). However, the pathophysiological underlying mechanisms are far from understood and likely multifactorial.

  • Insurance companies are using social media to increase visibility, enhance familiarity, develop relationships and build trust. Perhaps, presently, the primary advantage of using social media is to generate exposure. Another key use of social media by the insurance industry is to provide customer service in order to build and maintain relationships with consumers (see Appendix D for examples). The insurance industry has built its foundation on networking and building a good reputation.

  • The prominence of private health insurance has been buttressed by government interventions directed at PHI markets in several OECD health systems, although the effectiveness of policies aimed at increasing market size and fostering outcome quality has differed widely. Australia, Ireland, the Netherlands, Germany, Switzerland and the United States have promoted and maintained a large and viable private health insurance market because policy makers have concluded that mixed public-private coverage systems can better deliver desired health policy and social outcomes.

  • Inadvertent fetal exposure to contraceptive hormones is common, with a USA study estimating that approximately 70 000 fetuses are exposed to oral contraceptives annually.23 Most of the data on fetal outcomes relate to COC. The CEU found no studies that specifically assessed exposure through quick starting contraception. Studies are often limited by their observational nature, potential confounding factors and small sample size. Reassuringly there have been no consistent findings of specific fetal abnormalities.

  • building raised beds. Raised beds have soil a few inches or more higher than the surrounding area, which provides extra rooting depth, and helps the soil drain and warm up in the spring. They’re typically 3 to 4 feet wide, with mulched paths in between, so you walk on the paths and don’t compact the soil in planting areas. Raised bed sides can be made with reused lumber, broken concrete or concrete blocks, recycled plastic lum- ber, or any non-toxic material. (Don’t use treated wood.) You can also make raised beds without sides. Dig a few inches of soil out of...

  • A mandate requiring all individuals to pur- chase health insurance would be an unprece- dented form of federal action. The government has never required people to buy any good or service as a condition of lawful residence in the United States. An individual mandate would have two features that, in combination, would make it unique. First, it would impose a duty on individuals as members of society. Second, it would require people to purchase a specific service that would be heavily regu- lated by the federal government.
