  • Further, Fich and Shivdasani (2006) find that firms with a majority of their outside directors serving on three or more boards have lower profitability. Thus busy non- executive directors may be over-committed and therefore unable to fulfil the role of effective monitors. In addition, Vafeas (2003) reports that longer outside director tenure adversely affects firm performance. Hwang and Kim (2009) find that the existence of substantial social ties between outside directors and top management diminishes the effectiveness of the monitoring role of non-executive directors. ...

  • Eight different isomeric forms of vitamin E (4 tocopherols and 4 tocotrienols) have been found in nature. Tocotrienols (α, β, γ and δ) are identical in structure to tocopherols except for the degree of saturation in their side chain. However, α-tocopherol is considered to be the most active form of vitamin E in humans. It has been found that the concentrations of vitamin E isomers in human feces are higher than in plasma – possibly due to its limited absorption from the diet, suggesting that it could play a protective role against RONS produced in the GI tract (Halliwell...

  • Although we are primarily interested in the housing consumption of the elderly, we did not limit our analysis to the householders aged 62 and older. For comparison purposes, we looked at all householders. We did this by segregating the householder population into seven age cohorts. The number of age cohorts is large enough to let us capture changes in housing consumption over individuals’ lifecycle, without being overly burdensome on the analysis. The cohort widths have been defined such that they can mirror reasonable life bands.

  • The presence or lack of these five factors was the determinant of the role of religion in the given conflict. Due to the nature of this methodology these are debateable findings. For instance one leader may declare simply ‘May God bless us and watch over us’ whereas another may declare that ‘God calls us, his chosen people, to annihilate our enemies’. Both are employing a religious discourse yet there is clearly a difference in severity. Measuring this difference is...

  • The UK is an open economy and an active and successful international trader and investor. But the UK’s reliance on debt-financed consumer and government spending, and on the financial sector, has driven growing imbalances in the UK economy. According to the OECD, by 2007 the UK had the largest structural budget deficit in the G7 group of countries. The current account deficit was around 2¾% of GDP in 2007, a figure that was offset by a 2¼% surplus on trade in financial services.

  • However, there are patients with two negative biopsies who continue with a high suspicion of cancer, with a persistently elevated PSA or pre-malignant histology report such as prostate intraepithelial neoplasia grade 3 or atypical microacinar proliferation. The evidence suggests that cancers diagnosed with the third or fourth biopsy are those of low grade and volume (Djavan, 2001). The key question is how often is it justified to re-biopsy the patient that perhaps does not have a cancer that is life threatening.

  • An unusually large number of people sickened by a disease in a certain place and time is known as a ‘disease cluster’. Clusters of cancer, birth defects, and other chronic illnesses have sometimes been linked to chemicals or other toxic pollutants in local communities, although these links can be controversial. There is a need for better documentation and investigation of disease clusters to identify and address possible causes.

  • In the treatment of bone pain, the second step on the WHO analgesic ladder is commonly unhelpful, with inadequate pain relief or the development of undesirable/intolerable side-effects (Eisenberg, 2005). There is currently no place for interventional treatment on the ladder and the earlier recommendations of a fourth step of interventional management are not applied widely enough. The main principles of pain management, including the use of a biopsychosocial approach, should be applied, rather than simply following the WHO ladder.

  • But how “safe” is a savings account if you leave all of your money there for a long time, and the interest it earns doesn’t keep up with inflation? What if you save a dollar when it can buy a loaf of bread. But years later when you withdraw that dollar plus the interest you earned on it, it can only buy half a loaf? This is why many people put some of their money in savings, but look to investing so they can earn more over long periods of time, say three years or longer. Investing When you “invest,” you...

  • As the debate on the future of pain medicine unfolds, stakeholders at all levels are taking note of the exciting potential for an optimal system of pain care delivery. However, more delays in advancing the cause of pain medicine will place the United States further behind other countries, such as Australia and China, which have already recognized pain medicine as a medical specialty, and the European Union and Canada, which are also considering such a development.

Knowledge of how and why parasites vary to escape recognition by the immune system is central to vaccine design, the control of epidemics, and our fundamental understanding of parasite ecology and evolution. As the first comprehensive synthesis of parasite variation at the molecular, population, and evolutionary levels, this book is essential reading for students and researchers throughout biology and biomedicine....

  • An estimated 1.5 million deaths occur annually as a result of household air pollution from SFU mainly for cooking as well as winter season heating. The total disease burden, including morbidity, is estimated at 36 million DALYs (WHO 2007). 3 These deaths and DALYs arise mainly from acute lower respiratory infections (ALRI) in young children and chronic obstructive pulmonary disease (COPD) in adults, and to a lesser extent lung cancer. There is also moderate evidence of increased risk of asthma, cataracts and tuberculosis (Desai et al, 2004; Smith et al, 2004).

  • If the consumption of counterfeit goods is consistent with other forms of routine consumption practices, it is likely that they are purchased in everyday environments and situated within routine social contexts. Such a view is supported by the questionnaire data. Rather than being integrated into a subcultural technical elite, the most regular sites of purchase of counterfeit products were more mundane.

  • However, some focus group participants also found the use of electronic music “distracting.” Several students who disliked the use of DJ Spooky’s music accompanying Caligari noted being distracted by the modern drum loops and electronic sounds, claiming that they didn’t “suit” the film. Another student anonymously described having seen the film before, and feeling “far more removed from the film” because of the electronic music: “the experiment created an unconscious focus on where the film and the contemporary DJ track ‘synched’ up.
