Ragweed as an Example of Worldwide Allergen Expansion

<p/> <p>Multiple factors are contributing to the expansion of ragweed on a worldwide scale. This review seeks to examine factors that may contribute to allergen expansion with reference to ragweed as a well-studied example. It is our hope that increased surveillance for new pollens in areas not previously affected and awareness of the influence the changing environment plays in allergic disease will lead to better outcomes in susceptible patients.</p

Religion and happiness: Consensus, contradictions,comments and concerns

The relationship between religion and happiness has been the focus of much research. The present review provides a critical examination of this research and, in particular, focuses on conceptual and methodological concerns. The majority of studies report a positive association between measures of religion and happiness; however, contradictory findings are common. This is exemplified in the literature that has systematically employed the Francis Scale of Attitude toward Christianity alongside two different measures of happiness among a variety of samples. Two opposing conclusions have found consistent support. Research with the Oxford Happiness Inventory has consistently found religiosity to be associated with happiness, while research employing the Depression–Happiness Scale has consistently found no association. It is argued that such contradictions may reflect both conceptual and methodological weaknesses in this literature
